SECTION 2.01.     FORM AND DATING.


(a)      GENERAL.


                  The Notes and the Trustee's certificate of authentication
         shall be substantially in the form of Exhibit A hereto, which is hereby
         incorporated by reference and expressly made a part of this Indenture.
         The Notes may have notations, legends or endorsements required by law,
         stock exchange rule, agreements to which the Company is subject, if
         any, or usage (provided that any such notation, legend or endorsement
         is in a form acceptable to the Company). The Company shall furnish any
         such legend not contained in Exhibit A to the Trustee in writing. Each
         Note shall be dated the date of its authentication. The Notes shall be
         in denominations of $1,000 and integral multiples thereof. The terms
         and provisions of the Notes set forth in Exhibit A are part of this
         Indenture and to the extent applicable, the Company and the Trustee, by
         their execution and delivery of this Indenture, expressly agree to such
         terms and provisions and to be bound thereby. However, to the extent
         any provision

                                       7
<PAGE>   12

         of any Note conflicts with the express provisions of this Indenture,
         the provisions of this Indenture shall govern and be controlling.

                  (b) GLOBAL NOTES.


                  The Notes are being offered and sold by the Company pursuant
         to the Purchase Agreement. The Notes shall be offered and sold
         primarily to Qualified Institutional Buyers ("QIBs") in reliance on
         Rule 144A under the Securities Act ("RULE 144A"), as provided in the
         Purchase Agreement. The Notes shall be issued initially in the form of
         one or more permanent Global Notes in definitive, fully registered form
         without interest coupons with the Global Notes Legend ("GLOBAL NOTES
         LEGEND") and Restricted Notes Legend ("RESTRICTED NOTES LEGEND") set
         forth in Exhibit A hereto ("RULE 144A GLOBAL NOTE"), which shall be
         deposited on behalf of the purchasers of the Notes represented thereby
         with the Trustee, as custodian for the Depositary, and registered in
         the name of the Depositary or a nominee of the Depositary, duly
         executed by the Company and authenticated by the Trustee as hereinafter
         provided. The aggregate principal amount of the Rule 144A Global Note
         may from time to time be increased or decreased by adjustments made on
         the records of the Trustee and the Depositary or its nominee as
         hereinafter provided.


                  Notes transferred in reliance on Regulation S under the
         Securities Act ("REGULATION S") as provided in Section 2.06(a)(ii) and
         (v) hereof, shall be issued in the form of one or more permanent Global
         Notes in definitive, fully registered form without interest coupons
         with the Global Notes Legend and Restricted Notes Legend set forth in
         Exhibit A hereto (the "REGULATION S GLOBAL NOTE"), which shall be
         deposited on behalf of the transferees of the Notes represented thereby
         with the Trustee, as custodian, for the Depositary, and registered in
         the name of the Depositary or the nominee of the Depositary for the
         accounts of designated agents holding on behalf of the Euroclear System
         ("EUROCLEAR") or Clearstream Banking ("CLEARSTREAM"), duly executed by
         the Company and authenticated by the Trustee as hereinafter provided.
         The aggregate principal of the Regulation S Global Note may from time
         to time be increased or decreased by adjustments made on the records of
         the Trustee and the Depositary or its nominee as hereinafter provided.


                  So long as any Global Note is outstanding, owners of
         beneficial interests therein may transfer their interests therein only
         in reliance on Regulation S or to QIBs in reliance on Rule 144A in
         accordance with Section 2.06.

                  (c) BOOK-ENTRY PROVISIONS.


                  This Section 2.01(c) shall apply only to the Rule 144A Global
         Note and the Regulation S Global Note issued in the form of one or more
         permanent Global Notes (collectively, the "GLOBAL NOTES") deposited
         with or on behalf of the Depositary.


                  The Company shall execute and the Trustee shall, in accordance
         with this Section 2.01(c), authenticate and deliver initially one or
         more Global Notes that (a) shall be registered in the name of the
         Depositary for such Global Note or Global Notes or the nominee

                                       8
<PAGE>   13

         of such Depositary and (b) shall be delivered by the Trustee to such
         Depositary or pursuant to such Depositary's instructions or held by the
         Trustee as custodian for the Depositary.


                  Members of, or participants in, the Depositary ("AGENT
         MEMBERS") shall have no rights under this Indenture with respect to any
         Global Note held on their behalf by the Depositary or by the Trustee as
         the custodian of the Depositary or under such Global Note, and the
         Depositary may be treated by the Company, the Trustee and any agent of
         the Company or the Trustee as the absolute owner of such Global Note
         for all purposes whatsoever. Notwithstanding the foregoing, nothing
         herein shall prevent the Company, the Trustee or any agent of the
         Company or the Trustee from giving effect to any written certification,
         proxy or other authorization furnished by the Depositary or impair, as
         between the Depositary and its Agent Members, the operation of
         customary practices of such Depositary governing the exercise of the
         rights of an owner of a beneficial interest in any Global Note.

                  (d) CERTIFICATED NOTES.


                  So long as the Depositary or its nominee is the registered
         owner of a Note, the Depositary or such nominee, as the case may be,
         will be considered the sole owner or Holder of the Notes represented by
         the Global Notes for all purposes under the Indenture. Except as
         provided below, owners of beneficial interests in a Global Note will
         not be entitled to have Notes represented by such Global Note
         registered in their names, will not receive or be entitled to receive
         physical delivery of certificated Notes, and will not be considered the
         owners or holders thereof under the Indenture for any purpose,
         including with respect to the giving of any directions, instructions or
         approvals to the Trustee thereunder.


                  Other than as set forth below in this Section, certificated
         Notes will be issued to owners of beneficial interests in Global Notes
         in exchange for their interests in Global Notes only if (1) the Company
         notifies the Trustee in writing that the Depositary is no longer
         willing or able to act as a depositary and the Company is unable to
         locate a qualified successor within 90 days, or (2) the Company, at its
         option, notifies the Trustee in writing that it elects to cause the
         issuance of Notes in definitive form under the Indenture. In either
         case, upon surrender by the Depositary of the Global Notes,
         certificated Notes will be issued to each Person that the Depositary
         identifies as the beneficial owner of the Notes represented by the
         Global Notes. In addition, the Company will issue certificated Notes in
         exchange for interests in Global Notes upon the request of an owner of
         such an interest if an Event of Default has occurred and is continuing,
         in which case, upon receipt of such request and necessary information
         from the Depositary in accordance with its procedures, the principal
         Registrar shall instruct the Depositary as to the corresponding
         reduction to be made in the principal amount of the relevant Global
         Note. Finally, at such time as all Global Notes cease to be outstanding
         pursuant to clause (1) or (2) above, certificated Notes may be issued
         in accordance with paragraphs (vi) and (vii) of Section 2.06(a). Upon
         any such issuance, the Trustee shall register such certificated Notes
         in the name of such Person or Persons (or the nominee of any thereof),
         and cause the same to be delivered thereto. All such certificated Notes
         shall bear the Restricted Notes Legend set forth in Exhibit A hereto
         (collectively with the Accredited Investor Restricted Notes defined
         below, the "RESTRICTED NOTES") unless otherwise provided in this
         Section 2.01(d) and Section 2.06(b) hereof.

<PAGE>   14

                  Notes offered and sold to "accredited investors" (as defined
         in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities
         Act), as provided in the Purchase Agreement, shall be issued in the
         form of one or more certificated Notes (subject to a minimum initial
         purchase amount of $100,000) in definitive, fully registered form
         without interest coupons with the Restricted Notes Legend set forth in
         Exhibit A hereto ("ACCREDITED INVESTOR RESTRICTED NOTES"), which shall
         be registered in the name of such Accredited Investor or its nominee,
         duly executed by the Company and authenticated by the Trustee as
         hereinafter provided. So long as Global Notes have not ceased to be
         outstanding pursuant to clause (1) or (2) in the immediately preceding
         paragraph above (and unless such Accredited Investor Restricted Notes
         have been exchanged for certificated Notes without a Restricted Notes
         Legend pursuant to the last paragraph in this Section, if applicable),
         such Accredited Investor Restricted Notes may only be transferred in
         reliance on Regulation S (pursuant to Section 2.06(a)(iv))or to QIBs in
         reliance on Rule 144A (pursuant to Section 2.06(a)(v)). After such time
         as Global Notes have ceased to be outstanding pursuant to clauses (1)
         or (2) in the immediately preceding paragraph, Accredited Investor
         Restricted Notes may be transferred to transferees who hold the
         transferred interests in the form of certificated Notes in accordance
         with Section 2.06(a)(vii) or Section 2.06(b).


                  Notwithstanding the foregoing, Notes offered and sold on the
         Issuance Date to "accredited investors" (as defined above) shall be
         issued initially in the form of one or more permanent Global Notes in
         definitive, fully registered form without interest coupons with the
         Global Notes Legend and Restrictive Notes Legend set forth in Exhibit A
         (the "Accredited Investor Global Note"), which shall be deposited on
         behalf of the purchasers of the Notes represented thereby with the
         Trustee, as custodian for the Depositary, and registered in the name of
         the Depositary or a nominee of the Depositary, duly executed by the
         Company and authenticated by the Trustee as hereinafter provided. Such
         Accredited Investor Global Note shall be deemed to be a Global Note for
         all purposes of this Indenture. Promptly after the Issuance Date, the
         Company shall cause the purchasers of the Accredited Investor Global
         Note to arrange with the Depositary for the exchange of such Accredited
         Investor Global Note for Accredited Investor Restricted Notes. Upon
         receipt by the principal Registrar of instructions from the Depositary
         directing the principal Registrar to authenticate and deliver one or
         more Accredited Investor Restricted Notes of the same aggregate
         principal amount as the beneficial interest in the Accredited Investor
         Global Note to be exchanged, such instructions to contain the name or
         names of the Holder or Holders of such Accredited Investor Restricted
         Note or Notes, the authorized denominations of the Accredited Investor
         Restricted Note or Notes to be so issued and appropriate delivery
         instructions, the principal Registrar will instruct the Depositary to
         reduce the Accredited Investor Global Note by the aggregate principal
         amount of the beneficial interest therein to be exchanged and to debit
         from the account of the Person making such exchange the beneficial
         interest in the Accredited Investor Global Note that is being
         exchanged, and concurrently with such reduction and debit the Company
         shall execute, and the Trustee shall authenticate and deliver, one or
         more Accredited Investor Restricted Notes of the same aggregate
         principal amount in accordance with the instructions referred to above.
         Certificated Notes may be issued as aforesaid notwithstanding any other
         provision of this Indenture to the contrary restricting the issuance of
         certificated Notes.

                  After a transfer of any Notes during the period of the
         effectiveness of a Shelf Registration Statement with respect to the
         Notes and pursuant thereto, all requirements for Restricted Notes
         Legends on such Notes will cease to apply; and, in this case a
         certificated Note without a Restricted Notes Legend will be available
         to the Holder of such Restricted Notes upon request (and surrender of
         such Note bearing the Restricted Notes Legend for cancellation). The
         Company shall give written notice to the Trustee, in the form of an
         Officer's Certificate, of the effectiveness of the Shelf Registration
         Statement, on which the Trustee and Registrant may rely.

SECTION 2.02.     EXECUTION AND AUTHENTICATION.


                  One Officer shall sign the Notes for the Company by manual or
         facsimile signature.


                  If an Officer whose signature is on a Note no longer holds
         that office at the time the Note is authenticated, the Note shall
         nevertheless be valid.


                  A Note shall not be valid until authenticated by the manual
         signature of an authorized officer of the Trustee. The signature shall
         be conclusive evidence that the Note has been authenticated under this
         Indenture.


                  The Trustee shall, upon a written order of the Company signed
         by an Officer, authenticate one or more Notes for original issue up to
         an aggregate principal amount stated in Section 6 of the Notes. The
         aggregate principal amount of Notes outstanding at any time may not
         exceed $300,000,000 except as provided in Section 2.07; provided that
         Notes in excess of $250,000,000 shall not be issued other than pursuant
         to the over-allotment option granted by the Company to the Initial
         Purchasers as provided in the Purchase Agreement. In the event thereof,
         the Company shall certify to the Trustee in an Officer's Certificate
         that such issuance is pursuant to such over-allotment option granted by
         the Initial Purchasers under the Purchase Agreement.


                  The Trustee may appoint an authenticating agent acceptable to
         the Company to authenticate Notes. An authenticating agent may
         authenticate Notes whenever the Trustee may do so. Each reference in
         this Indenture to authentication by the Trustee includes authentication
         by such agent. An authenticating agent has the same rights as an Agent
         to deal with Holders, the Company or an Affiliate.

SECTION 2.03.     REGISTRAR AND PAYING AGENT.


                  The Company shall maintain in the Borough of Manhattan, City
         of New York, State of New York, an office or agency where the Notes may
         be presented for registration of transfer or for exchange, payment and
         conversion (collectively, the "NEW YORK PRESENTING AGENT"). The Company
         initially designates STATE STREET BANK AND TRUST COMPANY, N.A., an
         affiliate of the Trustee, at its corporate trust offices in the Borough
         of Manhattan, City of New York, State of New York to act as New York
         Presenting Agent. The Trustee is initially appointed to act as Note
         registrar to maintain a register of transfers of the Notes (the "NOTE
         REGISTRAR") and to act as paying agent with respect to the Notes
         ("PAYING AGENT") and to act as agent for conversion of the Notes
         ("CONVERSION AGENT"). The Registrar shall keep a register of the Notes
         and of their transfer and exchange. The Company may

                                       11

         appoint one or more co-Registrars, one or more additional Paying Agents
         and one or more additional Conversion Agents in such other locations as
         it shall determine. The term "Registrar" includes any co-Registrar, the
         term "Paying Agent" includes any additional Paying Agent and the term
         "Conversion Agent" includes any additional conversion agent. The
         Company may change any Paying Agent, Registrar, New York Presenting
         Agent or Conversion Agent without prior notice to any Holder. The
         Company shall notify the Trustee of the name and address of any Agent
         not a party to this Indenture. If the Company fails to appoint or
         maintain another entity as Registrar, Paying Agent, New York Presenting
         Agent or Conversion Agent, the Trustee shall act as such. The Company
         or any of its Affiliates may act as Paying Agent, Registrar, New York
         Presenting Agent or Conversion Agent.

SECTION 2.04.     PAYING AGENT TO HOLD MONEY IN TRUST.


                  The Company shall require each Paying Agent other than the
         Trustee to agree in writing that the Paying Agent will hold in trust
         for the benefit of Holders or the Trustee all money held by the Paying
         Agent for the payment of principal or interest on the Notes, and will
         notify the Trustee of any default by the Company in making any such
         payment. While any such default continues, the Trustee may require a
         Paying Agent to pay all money held by it to the Trustee and to account
         for any money disbursed by it. The Company at any time may require a
         Paying Agent to pay all money held by it to the Trustee. Upon payment
         over to the Trustee, the Paying Agent (if other than the Company or an
         Affiliate of the Company) shall have no further liability for the
         money. If the Company or an Affiliate of the Company acts as Paying
         Agent, it shall segregate and hold in a separate trust fund for the
         benefit of the Holders all money held by it as Paying Agent.

SECTION 2.05.       HOLDER LISTS.


                  The Trustee shall preserve in as current a form as is
         reasonably practicable the most recent list available to it of the
         names and addresses of Holders. If the Trustee is not the Registrar,
         the Company shall furnish to the Trustee on or before each interest
         payment date and at such other times as the Trustee may request in
         writing a list in such form and as of such date as the Trustee may
         reasonably require of the names and addresses of Holders.

SECTION 2.06.     TRANSFER AND EXCHANGE.


                  Whenever Notes are presented to the Registrar or a
         co-Registrar with a request to register a transfer or to exchange them
         for an equal principal amount of Notes of other denominations, the
         Registrar shall register the transfer or make the exchange if its
         requirements for such transactions are met. To permit registrations of
         transfers and exchanges, the Company shall issue and the Trustee shall
         authenticate Notes at the Registrar's request. No service charge shall
         be made to a Holder for any registration of transfer or exchange
         (except as otherwise expressly permitted herein), but the Company may
         require payment of a sum sufficient to cover any transfer tax or
         similar governmental charge payable in connection therewith (other than
         any such transfer tax or similar governmental charge payable upon
         exchanges pursuant to Sections 2.10, 3.06 or 11.05 hereof).

         long as a Global Note remains outstanding and is held by or on behalf
         of the Depositary, transfers of a Global Note, in whole or in part, or
         of any beneficial interest therein, shall only be made in reliance on

         Section 2.01(b), Section 2.01(d), Section 2.06(a) and Section 2.06(b);
         provided, however, that beneficial interests in a Global Note may be
         transferred to Persons who take delivery thereof in the form of a
         beneficial interest in the same Global Note in accordance with the
         transfer restrictions set forth in the Restricted Notes Legend and
         under the heading "Notice to Investors" in the Company's Offering

                       legal opinions or other information as the Company may
                       reasonably require to confirm that such transfer is being
                       made pursuant to an exemption from, or in a transaction
                       not subject to, the registration requirements of the
                       Securities Act, then the principal Registrar will
                       instruct the Depositary to reduce or cause to be reduced
                       such Global Note by the aggregate principal amount of the
                       beneficial interest therein to be exchanged and to debit
                       or cause to be debited from the account of the Person
                       making such transfer the beneficial interest in the
                       Global Note that is being transferred, and concurrently
                       with such reduction and debit the Company shall execute,
                       and the Trustee shall authenticate and deliver, one or
                       more Restricted Notes of the same aggregate principal
                       amount in accordance with the instructions referred to
                       above. In the event that certificated Notes are issued in
                       place of beneficial interests in Global Notes pursuant to

                       Notes may be exchanged only in accordance with such
                       procedures as are substantially consistent with the
                       provisions of clauses (ii) and (iii) above (including the

                       such Notes other than in reliance on Regulation S or to
                       QIBs in reliance on Rule 144A in certificated form
                       pursuant to Section 2.01(d), if a Holder of a Restricted
                       Note wishes to transfer such Restricted Note to a Person
                       who is required to take delivery thereof in the form of a
                       Restricted Note, such Holder may, subject to the
                       restrictions on transfer set forth herein and in such
                       Restricted Note, cause the exchange of such Restricted

                       denomination or denominations and of the same aggregate
                       principal amount. Upon receipt by the principal Registrar

                       instructions to contain the name or authorized
                       denomination or denominations of the Restricted Notes to

                       certificate from the Holder of the Restricted Note to be
                       exchanged in the form of Exhibit D attached hereto, (4) a
                       certificate in the form of Exhibit E attached hereto
                       given by the Person acquiring the Restricted Notes for
                       which such interest is being exchanged, if such Person is
                       an "accredited investor" as defined and to the effect set
                       forth therein, and (5) such other certifications, legal
                       opinions or other information as the Company may

                       made pursuant to an exemption from, or in a transaction
                       not subject to, the registration requirements of the
                       Securities Act, then the Registrar shall cancel or cause
                       to be canceled such Restricted Note and concurrently
                       therewith, the Company shall execute, and the Trustee
                       shall authenticate and deliver, one or more Restricted
                       Notes of the same aggregate principal amount, in
                       accordance with the instructions referred to above.

                       (b) Upon any sale of a Note bearing the Restricted Notes
                    Legend (or any interest in a Global Note subject to the
                    Restricted Notes Legend) pursuant to Rule 144 under the
                    Securities Act or an effective registration statement under
                    the Securities Act:

                          (i) (A) in the case of any Note that is a certificated
                       Note or a beneficial interest in a Global Note, the
                       Registrar shall permit the Holder thereof to exchange
                       such Note or interest for a certificated Note or a
                       beneficial interest in a Global Note, as the case may be,
                       that does not bear or is subject to, as the case may be,
                       the legend set forth above and rescind any restriction on
                       the transfer of such Note or interest (1) in the case of
                       a sale or transfer pursuant to Rule 144 under the
                       Securities Act, upon delivery to the Company such
                       satisfactory evidence, which may include an opinion of
                       counsel licensed to practice law in the State of New
                       York, as may be reasonably required by the Company, that
                       neither the legend nor the restrictions on transfer set

                       forth therein are required to ensure that transfers
                       thereof comply with the provisions of Rule 144A, Rule
                       144, Regulation S or any other available exemption from
                       registration under the Securities Act or, with respect to
                       Restricted Notes, that such Notes are not "restricted"
                       within the meaning of Rule 144 under the Securities Act
                       or (2) in the case of a sale or transfer pursuant to an
                       effective registration statement under the Securities
                       Act; and

                          (ii) any Global Note shall not be subject to the
                       Restricted Notes Legend (such sales or transfers being
                       subject only to the provisions of Section 2.06(a)(i) and
                       Section 2.01(d)).


                  Upon provision of such satisfactory evidence, the Trustee, at
         the direction of the Company, shall authenticate and deliver Notes that
         do not bear the Restricted Notes Legend.

                  (c) Neither the Company nor the Trustee shall have any
         responsibility for any actions taken or not taken by the Depositary and
         the Company shall have no responsibility for any actions taken or not
         taken by the Trustee as agent or custodian of the Depositary.

                  (d) Notwithstanding anything contained herein to the contrary,
         neither the Trustee nor the Note Registrar shall be responsible for
         ascertaining whether any purchase or transfer complies with the
         registration provisions of or exemptions from the Securities Act, Rule
         144A, Rule 144, Regulation S, or any applicable state securities laws;
         provided, that if a certificate or other written representation is
         specifically required by the express terms of this Section 2.06 to be
         delivered to the Registrar or Trustee by a transferee of a Note prior
         to registration of such transfer, the Trustee or Note Registrar, as the
         case may be, shall be under a duty to receive and examine the same to
         determine whether it conforms on its face to the requirements of this
         Section 2.06.


                  (e) Transfers of any Notes in certificated form not bearing
         the Restricted Notes Legend shall not be subject to the restrictions
         and requirements set forth in Section 2.06(a)(vii).

                  (f) Any transfer or exchange of a Note in certificated form
         shall be accompanied by surrender of the certificated Note, endorsed or
         accompanied by an instrument of transfer acceptable to the Registrar,
         executed by the Holder or an attorney in fact acting on its behalf.

SECTION 2.07.     REPLACEMENT NOTES.


                  If the Holder of a Note claims that the Note has been lost,
         destroyed or wrongfully taken or if such Note is mutilated and is
         surrendered to the Trustee, the Company shall issue and the Trustee
         shall authenticate a replacement Note if the Trustee's and the
         Company's requirements are met. If required by the Trustee or the
         Company, an indemnity bond must be supplied by the Holder that is
         sufficient in the judgment of both to protect the Company, the Trustee,
         any Agent or any authenticating agent from any loss which any of them
         may suffer if a Note is replaced. The Company may charge for its
         expenses in replacing a Note.


                  In case any such mutilated, destroyed, lost or stolen Note has
         become or is about to become due and payable, or is about to be
         purchased by the Company pursuant to Article III

                                       17
<PAGE>   22
                  hereof, the Company in its discretion may, instead of issuing
                  a new Note, pay or purchase such Note, as the case may be.


                  Every replacement Note is an additional obligation of the
         Company and shall be entitled to all of the benefits of this Indenture
         equally and proportionately with all other Notes duly issued hereunder.

SECTION 2.08.     OUTSTANDING NOTES.


                  The Notes outstanding at any time are all the Notes
         authenticated by the Trustee except for those canceled by it, those
         delivered to it for cancellation, and those described in this Section
         as not outstanding.


                  If a Note is replaced, paid or purchased pursuant to Section
         2.07 hereof, it ceases to be outstanding unless the Trustee receives
         proof satisfactory to it that the replaced, paid or purchased Note is
         held by a bona fide purchaser.


                  If the principal amount of any Note is considered paid under
         Section 4.01 hereof, it ceases to be outstanding and interest on it
         ceases to accrue.


                  Except as set forth in Section 2.09 hereof, a Note does not
         cease to be outstanding because the Company or an Affiliate of the
         Company holds the Note.

SECTION 2.09.     TREASURY NOTES.


                  In determining whether the Holders of the required principal
         amount of Notes have concurred in any direction, waiver or consent,
         Notes owned by the Company or an Affiliate of the Company shall be
         considered as though they are not outstanding, except that for the
         purposes of determining whether the Trustee shall be protected in
         relying on any such direction, waiver or consent, only Notes that the
         Trustee knows are so owned shall be so disregarded.

SECTION 2.10.     TEMPORARY NOTES; GLOBAL NOTES.

                  (a) Until definitive Notes are ready for delivery, the Company
         may prepare and the Trustee shall authenticate temporary Notes.
         Temporary Notes shall be substantially in the form of definitive Notes
         but may have variations that the Company considers appropriate for
         temporary Notes. Without unreasonable delay, the Company shall prepare
         and the Trustee shall authenticate definitive Notes in exchange for
         temporary Notes. Holders of temporary Notes shall be entitled to all of
         the benefits of this Indenture.

                  (b) A Global Note deposited with the Depositary or with the
         Trustee as custodian for the Depositary pursuant to Section 2.01 shall
         be transferred to the beneficial owners thereof in the form of
         certificated Notes only (i) in accordance with Section 2.01(d), and
         (ii) provided that such transfer complies with the applicable
         provisions of Section 2.06(b).

                  (c) Any Global Note that is re-issued to the beneficial owners
         thereof in the form of certificated Notes pursuant to Section 2.01(d)
         and this Section 2.10 shall be surrendered by

                                       18
<PAGE>   23
         the Depositary to the Trustee to be so transferred without charge, and
         the Trustee shall authenticate and deliver, upon such transfer of each
         portion of such Global Note, an equal aggregate principal amount of
         Notes of authorized denominations in the form of certificated Notes.
         Any portion of a Global Note transferred pursuant to this Section 2.10
         shall be executed, authenticated and delivered as the Depositary shall
         direct. Any Note in the form of certificated Notes delivered in
         exchange for an interest in the Global Notes shall, except as otherwise
         provided by Section 2.06(c), bear the Restricted Notes Legend set forth
         in Exhibit A hereto.

                  (d) Upon the occurrence of any of the events set forth in
         Section 2.01(d) requiring the issuance of certificated Notes in place
         of all beneficial interests in Global Notes then outstanding, the
         Company will promptly make available to the Trustee a reasonable supply
         of certificated Notes in definitive, fully registered form without
         interest coupons.

SECTION 2.11.     CANCELLATION.


                  The Company at any time may deliver Notes to the Trustee for
         cancellation. The Registrar, Paying Agent and Conversion Agent shall
         forward to the Trustee any Notes surrendered to them for registration
         of transfer, exchange or payment. The Trustee shall promptly cancel all
         Notes surrendered for registration of transfer, exchange, payment,
         conversion, replacement or cancellation and shall dispose of canceled
         Notes as the Company directs. The Company may not issue new Notes to
         replace Notes that it has paid or that have been delivered to the
         Trustee for cancellation.

SECTION 2.12.     DEFAULTED INTEREST.


                  If the Company fails to make a payment of interest on the
         Notes, it shall pay such defaulted interest plus any interest payable
         on the defaulted interest, in any lawful manner. It may pay such
         defaulted interest, plus any such interest payable on it, to the
         Persons who are Holders on a subsequent special record date. The
         Company shall fix any such record date and payment date, provided that
         no such record date shall be less than 10 days prior to the related
         payment date for such defaulted interest. At least 15 days before any
         such record date, the Company shall mail to Holders a notice that
         states the special record date, the related payment date and amount of
         such interest to be paid.

SECTION 2.13.     CUSIP NUMBERS.


                  The Company in issuing the Notes may use "CUSIP" numbers (if
         then generally in use), and, if so, the Trustee shall use "CUSIP"
         numbers in notices of redemption and other notices as a convenience to
         holders of Notes; provided, that any such notice may state that no
         representation is made as to the correctness of such numbers either as
         printed on the Notes or as contained in any notice of a redemption or
         notice of a Purchase Offer and that reliance may be placed only on the
         other identification numbers printed on the Notes, and any redemption
         or Purchase Offer shall not be affected by any defect in or omission of
         such numbers. The Company will promptly notify the Trustee of any
         change in the "CUSIP" numbers.

                                   REDEMPTION

SECTION 3.01.    NOTICES TO TRUSTEE.


                  If the Company elects to redeem Notes pursuant to the optional
         redemption provisions of the Notes and Section 3.07 hereof, it shall
         notify the Trustee in writing of the redemption date and the principal
         amount of Notes to be redeemed. The Company shall give the notice
         provided for in this Section 3.01 at least 45 days before the
         redemption date, unless a shorter notice period shall be satisfactory
         to the Trustee. The Company may not give notice of any redemption if
         the Company has defaulted in payment of interest and the default is
         continuing.

SECTION 3.02.     SELECTION OF NOTES TO BE REDEEMED.


                  If less than all of the Notes are to be redeemed at any time,
         selection of Notes shall be made by the Trustee on a pro rata basis or
         by lot or by a method that complies with the requirements of any
         exchange on which the Notes are listed and that the Trustee considers
         fair and appropriate, provided that no Notes of $1,000 or less shall be
         redeemed in part. The Trustee shall make the selection not more than 60
         days and not less than 30 days before the redemption date from Notes
         outstanding not previously called for redemption. Notes and portions of
         Notes selected shall be in amounts of $1,000 or integral multiples of
         $1,000. Provisions of this Indenture that apply to Notes called for
         redemption also apply to portions of Notes called for redemption. The
         Trustee shall notify the Company promptly of the Notes or portions of
         Notes to be called for redemption.


                  If any Note selected for partial redemption is converted in
         part after such selection, the converted portion of such Note shall be
         deemed (so far as may be) to be the portion to be selected for
         redemption. The Notes (or portions thereof) so selected shall be deemed
         duly selected for redemption for all purposes hereunder,
         notwithstanding that any such Note is converted in whole or in part
         before the mailing of the notice of redemption. Upon any redemption of
         less than all the Notes, the Company and the Trustee may treat as
         outstanding any Notes surrendered for conversion during the period 15
         days next preceding the mailing of a notice of redemption and need not
         treat as outstanding any Note authenticated and delivered during such
         period in exchange for the unconverted portion of any Note converted in
         part during such period.

SECTION 3.03.     NOTICE OF REDEMPTION.


                  At least 30 days but not more than 60 days before a redemption
         date, the Company shall mail, by first class mail, a notice of
         redemption to each Holder whose Notes are to be redeemed at its
         registered address. The notice shall identify the Notes to be redeemed
         and shall state:

                  (a) the redemption date;

                  (b) the redemption price;

                                       20
<PAGE>   25

                  (c) if any Note is to be redeemed in part only, the portion of
         the principal amount thereof redeemed, and that, after the redemption

         having provided to the Trustee the requisite information therefor)
         shall send, by first class mail, a notice to each of the Holders, which
         shall govern the terms of the Purchase Offer and shall state:

                           (i) that the Purchase Offer is being made pursuant to

                  or accepted for payment will continue to accrue interest;

                           (iv) that, unless the Company defaults in the payment
                  of the purchase price, any Note or portion thereof accepted
                  for payment pursuant to the Purchase Offer will cease to
                  accrue interest after the Purchase Date;


                           (v) that Holders electing to have a Note or portion
                  thereof purchased pursuant to any Purchase Offer will be
                  required to surrender the Note, with the form entitled "Option
                  of Holder to Elect Purchase" on the reverse of the Note
                  completed, to the Company, a depositary, if appointed by the
                  Company, or a Paying Agent at the address specified in the
                  notice prior to the close of business on the third Business
                  Day preceding the Purchase Date;


                           (vi) that Holders will be entitled to withdraw their
                  election if the Company, depositary or Paying Agent, as the
                  case may be, receives, not later than the close of business on
                  the second Business Day preceding the Purchase Date, or such
                  longer period as may be required by law, a letter or a
                  telegram, telex or facsimile transmission (receipt of which is
                  confirmed and promptly followed by a letter) setting forth the
                  name of the Holder, the principal amount of the Note or
                  portion thereof the Holder delivered for purchase and a
                  statement that such Holder is withdrawing his election to have
                  the Note or portion thereof purchased;


                           (vii) that Holders whose Notes were purchased only in
                  part will be issued new Notes equal in principal amount to the
                  unpurchased portion of the Notes surrendered and


                           (viii) the "CUSIP" number of the Notes to be
                  purchased.


                         (f) On or prior to 1:00 pm (Boston time) on the
          Purchase Date, the Company shall irrevocably deposit with the Trustee
          or a Paying Agent in immediately available funds an amount equal to
          the Offer Amount to be held for payment in accordance with the terms
          of this Section 3.09. On the Purchase Date, the Company shall, to the
          extent lawful, (i) accept for payment the Notes or portions thereof
          properly tendered pursuant to the Purchase Offer, (ii) deliver or
          cause the Depositary or Paying Agent to deliver to the Trustee Notes
          so accepted and (iii) deliver to the Trustee an Officers' Certificate
          stating such Notes or portions thereof have been accepted for payment
          by the Company in accordance with the terms of this Section 3.09. The
          Depositary, the Paying Agent or the Company, as the case may be, shall
          promptly (but in any case not later than ten (10) calendar days after
          the Purchase Date) mail or deliver to each tendering Holder an amount
          equal to the purchase price of the Notes tendered by such Holder and
          accepted by the Company for purchase, and the Trustee shall promptly
          authenticate and mail or deliver to such Holders a new Note equal in
          principal amount to any unpurchased portion of the Note surrendered.
          Any Notes not so accepted shall be promptly mailed or delivered by or
          on behalf of the Company to the Holder thereof. The Company will
          publicly announce in a newspaper of general circulation the results of
          the Purchase Offer on or as soon as practicable after the Purchase
          Date.

         and interest on, the Notes on the dates and in the manner provided in
         the Notes. Principal, premium, if any, and interest shall be considered
         paid on the date due if the Paying Agent (other than the Company or an
         Affiliate of the Company) holds on that date money designated for and
         sufficient to pay all principal, premium, if any, and interest then
         due. To the extent lawful, the Company shall pay interest (including

         Notes, compounded semiannually; and (ii) overdue installments of
         interest (without regard to any applicable grace period) at the same

                  Whenever in this Indenture or the Notes there is mentioned, in
         any context, the payment of principal (and premium, if any), Offer
         Amount, interest or any other amount payable under or with respect to
         any Note, such mention shall be deemed to include mention of the
         payment of Special Interest provided for in Section 2 of the Notes to
         the extent that, in such context, Special Interest is, was or would be
         payable in respect thereof pursuant to the provisions of Section 2 of
         the Notes, and express mention of the payment of Special Interest (if
         applicable) in any provisions hereof shall not be construed as
         excluding Special Interest in those provisions hereof where such
         express mention is not made (if applicable).

SECTION 4.02      REPORTS.


                  Whether or not required by the rules and regulations of the
         SEC, so long as any Notes are outstanding, the Company shall file with

         quarterly and annual financial information required to be contained in
         a filing with the SEC on Forms 10-Q and 10-K, including a "Management's
         Discussion and Analysis of Results of Operations and Financial
         Condition" and, with respect to the annual information only, a report
         thereon by the Company's certified independent accountants, in each
         case, as required by the rules and regulations of the SEC as in effect
         on the Issuance Date. The Trustee shall be under no obligation or duty
         to review such reports, such delivery to it being for the purpose of
         having the same on file with the Trustee and available for examination.

SECTION 4.03.     COMPLIANCE CERTIFICATE.


                           The Company shall deliver to the Trustee, within 90
                  days after the end of each fiscal year of the Company, an

                  Company and its subsidiaries during the preceding fiscal year
                  has been made under the supervision of the signing Officers
                  with a view to determining whether the Company has kept,
                  observed, performed and fulfilled its obligations under, and
                  complied with the covenants and conditions contained in, this
                  Indenture, and further stating, as to each such Officer
                  signing such certificate, that to the best of his knowledge
                  the Company has kept, observed, performed and fulfilled each
                  and every covenant, and complied with the covenants and
                  conditions contained in this Indenture and is not in default
                  in the performance or observance of any of the terms,
                  provisions and conditions hereof (or, if a Default or Event of
                  Default shall have occurred, describing all such Defaults or
                  Events of Default of which he may have knowledge) and that to
                  the best of his knowledge no event has occurred and remains in
                  existence by reason of which payments on account of the
                  principal or of interest, if any, on the Notes are prohibited.
                  One of the Officers signing such Officers' Certificate shall
                  be either the Company's principal executive officer, principal
                  financial officer or principal accounting officer.


                           The Company will, so long as any of the Notes are
                  outstanding, deliver to the Trustee forthwith upon becoming
                  aware of any Default or Event of Default, an Officers'
                  Certificate specifying such Default or Event of Default.


                           Immediately upon the occurrence of any Registration
                  Default giving rise to Special Interest or the cure of any
                  such Registration Default, the Company shall give the Trustee
                  written notice thereof and of the event giving rise to such
                  Registration Default or the cure of any such Registration
                  Default (such notice to be contained in an Officers'
                  Certificate) and prior to receipt of such Officers'
                  Certificate the Trustee shall be entitled to assume that no
                  such Registration Default has occurred or been cured, as the
                  case may be.

SECTION 4.04.     STAY, EXTENSION AND USURY LAWS.


                           The Company covenants (to the extent that it may
                  lawfully do so) that it will not at any time insist upon,
                  plead, or in any manner whatsoever claim or take the benefit
                  or advantage of, any stay, extension or usury law wherever
                  enacted, now or at any time hereafter in force, which may
                  affect the covenants or the performance of this Indenture; and
                  the Company (to the extent it may lawfully do so) hereby
                  expressly waives all benefit or advantage of any such law, and
                  covenants that it will not, by resort to any such law, hinder,
                  delay or impede the execution of any power herein granted to
                  the Trustee, but will suffer and permit the execution of every
                  such power as though no such law had been enacted.

SECTION 4.05.     CORPORATE EXISTENCE.


                           Subject to Article VII hereof, to the extent
                  permitted by law the Company will do or cause to be done all
                  things necessary to preserve and keep in full force and effect
                  its corporate existence and the corporate, partnership or
                  other existence of each subsidiary of the Company in
                  accordance with the respective organizational documents of
                  each subsidiary and the rights (charter and statutory),
                  licenses and franchises of the Company; provided, however,
                  that the Company shall not be required to preserve any such
                  right, license or franchise, or the corporate, partnership or
                  other existence of any subsidiary, if the preservation thereof
                  is no

                  and its subsidiaries taken as a whole.

SECTION 4.06.     TAXES.


                           The Company shall, and shall cause each of its
                  subsidiaries to, pay prior to delinquency all material taxes,
                  assessments and governmental levies, except as contested in
                  good faith and by appropriate proceedings.

SECTION 4.07.     FUNDAMENTAL CHANGE.

                           (a) Upon the occurrence of a Fundamental Change, each
                  Holder of Notes shall have the right to require the Company to
                  repurchase all or any part (equal to $1,000 or an integral
                  multiple thereof) of such Holder's Notes pursuant to the
                  Purchase Offer at a purchase price equal to 100% of the
                  principal amount thereof plus accrued and unpaid interest to
                  the date of purchase (the "FUNDAMENTAL CHANGE PAYMENT").

                           (b) Within 25 days following any Fundamental Change,
                  the Company shall give written notice to the Trustee and shall
                  mail to each Holder the notice provided by Section 3.09(e).

SECTION 4.08.     LIMITATION ON STATUS AS INVESTMENT COMPANY.


                           The Company shall not, and shall not permit any
                  Subsidiary to, conduct its business in a fashion that would
                  cause the Company to be required to be registered as an
                  "investment company" (as that term is defined in the
                  Investment Company Act of 1940, as amended).

SECTION 4.09.     SPECIAL INTEREST.


                           If Special Interest is payable by the Company
                  pursuant to Section 2 of the Notes, the Company shall deliver
                  to the Trustee a certificate to that effect stating (i) the
                  amount of such Special Interest that is payable and (ii) the
                  date on which such Special Interest is payable. Unless and
                  until a Trust Officer of the Trustee receives such a
                  certificate, the Trustee may assume without inquiry that no
                  such Special Interest is payable. If the Company has paid
                  Special Interest directly to the persons entitled to it, the
                  Company shall deliver to the Trustee a certificate setting
                  forth the particulars of such payment.

         Date and prior to maturity at the Conversion Price then in effect,
         except that, with respect to any Note called for redemption, such
         conversion right shall terminate at the close of business on the
         Business Day immediately preceding the redemption date (unless the
         Company shall default in making the redemption payment when it becomes
         due, in which case the conversion right shall terminate



                                       26

         on the date such default is cured). The number of shares of Common
         Stock issuable upon conversion of a Note is determined by dividing the
         principal amount of such Note by the conversion price in effect on the
         Conversion Date (the "CONVERSION PRICE").


                  The initial Conversion Price is stated in Section 12 of the
         Notes and is subject to adjustment as provided in this Article V.


                  A Holder may convert a portion of a Note equal to any integral
         multiple of $1,000. Provisions of this Indenture that apply to
         conversion of all of a Note also apply to conversion of a portion of
         it.

SECTION 5.02.     CONVERSION PROCEDURE.


                  To convert a Note, a Holder must satisfy the requirements in
         Section 12 of the Notes. The date on which the Holder satisfies all of
         those requirements is the conversion date (the "CONVERSION DATE"). As
         soon as practicable after the Conversion Date, the Company shall
         deliver to the Holder through the Conversion Agent a certificate for
         the number of whole shares of Common Stock issuable upon the conversion
         and a check for any fractional share determined pursuant to Section
         5.03 hereof. The Person in whose name the certificate is registered
         shall become the stockholder of record on the Conversion Date and, as
         of such date, such Person's rights as a Holder of Notes hereunder shall
         cease (such Person's rights as a Holder of Transfer Restricted
         Securities, if any, under the Registration Rights Agreement, however,
         shall continue so long as such Person holds such Transfer Restricted
         Securities); provided, however, that no surrender of a Note on any date
         when the stock transfer books of the Company shall be closed shall be
         effective to constitute the Person entitled to receive the shares of
         Common Stock upon such conversion as the stockholder of record of such
         shares of Common Stock on such date, but such surrender shall be
         effective to constitute the Person entitled to receive such shares of
         Common Stock as the stockholder of record thereof for all purposes at
         the close of business on the next succeeding day on which such stock
         transfer books are open; provided further, however, that such
         conversion shall be at the Conversion Price in effect on the date that
         such Note shall have been surrendered for conversion, as if the stock
         transfer books of the Company had not been closed.


                  No payment or adjustment will be made for accrued and unpaid
         interest on a converted Note, but if any Holder surrenders a Note for
         conversion after the close of business on the record date for the
         payment of an installment of interest and prior to the opening of
         business on the next interest payment date, then, notwithstanding such
         conversion, the interest payable on such interest payment date shall be
         paid to the Holder of such Note on such record date. Any Notes that
         are, however, delivered to the Company for conversion after any record
         date but before the next interest payment date must, except as
         described in the next sentence, be accompanied by a payment equal to
         the interest payable on such interest payment date on the principal
         amount of convertible notes being converted. The payment to the Company
         described in the preceding sentence shall not be required if, during
         that period between a record date and the next interest payment date, a
         conversion occurs on or after the date that the Company has issued a
         redemption notice and prior to the date of redemption stated in such
         notice. If any Notes are converted after an interest payment date but
         on or before the next


                                       27
<PAGE>   32

         record date, no interest will be paid on those Notes. No fractional
         shares will be issued upon conversion, but a cash adjustment will be
         made for any fractional shares.


                  If a Holder converts more than one Note at the same time, the
         number of whole shares of Common Stock issuable upon the conversion
         shall be based on the total principal amount of Notes converted.


                  Upon surrender of a Note that is converted in part, the
         Trustee shall authenticate for the Holder a new Note equal in principal
         amount to the unconverted portion of the Note surrendered.

SECTION 5.03.     FRACTIONAL SHARES.


                  The Company will not issue fractional shares of Common Stock
         upon conversion of a Note. In lieu thereof, the Company will pay an
         amount in cash based upon the Daily Market Price of the Common Stock on
         the trading day prior to the date of conversion.

SECTION 5.04.     TAXES ON CONVERSION.


                  The issuance of certificates for shares of Common Stock upon
         the conversion of any Note shall be made without charge to the
         converting Holder for such certificates or for any tax in respect of
         the issuance of such certificates, and such certificates shall be
         issued in the respective names of, or in such names as may be directed
         by, the Holder or Holders of the converted Note; provided, however,
         that in the event that certificates for shares of Common Stock are to
         be issued in a name other than the name of the Holder of the Note
         converted, such Note, when surrendered for conversion, shall be
         accompanied by an instrument of transfer, in form satisfactory to the
         Company, duly executed by the registered Holder thereof or his duly
         authorized attorney; and provided further, however, that the Company
         shall not be required to pay any tax which may be payable in respect of
         any transfer involved in the issuance and delivery of any such
         certificates in a name other than that of the Holder of the converted
         Note, and the Company shall not be required to issue or deliver such
         certificates unless or until the Person or Persons requesting the
         issuance thereof shall have paid to the Company the amount of such tax
         or shall have established to the satisfaction of the Company that such
         tax has been paid or is not applicable.

SECTION 5.05.     COMPANY TO PROVIDE STOCK.


                  The Company shall at all times reserve and keep available,
         free from preemptive rights, out of its authorized but unissued Common
         Stock, solely for the purpose of issuance upon conversion of Notes as
         herein provided, a sufficient number of shares of Common Stock to
         permit the conversion of all outstanding Notes for shares of Common
         Stock. All shares of Common Stock which may be issued upon conversion
         of the Notes shall be duly authorized, validly issued, fully paid and
         nonassessable when so issued. Shares of Common Stock issuable upon
         conversion of a Restricted Note shall bear such restrictive legends as
         the Company shall provide in accordance with applicable law. If shares
         of Common Stock are to be issued upon conversion of a Restricted Note
         and they are to be registered in a name other than that of the holder
         of such Restricted Note, then the Person in whose name such shares of
         Common Stock are to be registered must deliver to the Trustee a
         certificate satisfactory to the



                                       28
<PAGE>   33

         Company and signed by such Person as to compliance with the
         restrictions on transfer contained in such restrictive legends.

SECTION 5.06.     ADJUSTMENT OF CONVERSION PRICE.


                  The Conversion Price shall be subject to adjustment from time
         to time as follows:

                  (a) In case the Company shall (1) pay a dividend in shares of
         Common Stock to holders of Common Stock, (2) make a distribution in
         shares of Common Stock to holders of Common Stock, (3) subdivide its
         outstanding shares of Common Stock into a greater number of shares of
         Common Stock or (4) combine its outstanding shares of Common Stock into
         a smaller number of shares of Common Stock, the Conversion Price in
         effect immediately prior to such action shall be adjusted so that the
         Holder of any Note thereafter surrendered for conversion shall be
         entitled to receive the number of shares of Common Stock which he would
         have owned immediately following such action had such Notes been
         converted immediately prior thereto. Any adjustment made pursuant to
         this subsection (a) shall become effective immediately after the record
         date in the case of a dividend or distribution and shall become
         effective immediately after the effective date in the case of a
         subdivision or combination.

                  (b) In case the Company shall issue rights or warrants to
         substantially all holders of Common Stock entitling them (for a period
         commencing no earlier than the record date for the determination of
         holders of Common Stock entitled to receive such rights or warrants and
         expiring not more than 45 days after such record date) to subscribe for
         or purchase shares of Common Stock (or securities convertible into
         Common Stock) at a price per share less than the current market price
         (as determined pursuant to subsection (f) below) of the Common Stock on
         such record date, the Conversion Price shall be adjusted so that the
         same shall equal the price determined by multiplying the Conversion
         Price in effect immediately prior to such record date by a fraction of
         which the numerator shall be the number of shares of Common Stock
         outstanding on such record date, plus the number of shares of Common
         Stock which the aggregate offering price of the offered shares of
         Common Stock (or the aggregate conversion price of the convertible
         securities so offered) would purchase at such current market price, and
         of which the denominator shall be the number of shares of Common Stock
         outstanding on such record date plus the number of additional shares of
         Common Stock offered (or into which the convertible securities so
         offered are convertible). Such adjustments shall become effective
         immediately after such record date.

                  (c) In case the Company shall distribute to all holders of
         Common Stock shares of capital stock of the Company other than Common
         Stock, evidences of indebtedness or other assets (other than cash
         dividends out of current or retained earnings), or shall distribute to
         substantially all holders of Common Stock rights or warrants to
         subscribe for securities (other than those referred to in subsection
         (b) above), then in each such case the Conversion Price shall be
         adjusted so that the same shall equal the price determined by
         multiplying the Conversion Price in effect immediately prior to the
         date of such distribution by a fraction of which the numerator shall be
         the current market price (determined as provided in subsection (f)
         below) of the Common Stock on the record date mentioned below less the
         then fair market value (as determined by the Board of Directors, whose
         determination shall be



                                       29
<PAGE>   34

         conclusive evidence of such fair market value and described in a Board
         Resolution) of the portion of the assets so distributed or of such
         subscription rights or warrants applicable to one share of Common
         Stock, and of which the denominator shall be such current market price
         of the Common Stock. Such adjustment shall become effective immediately
         after the record date for the determination of the holders of Common
         Stock entitled to receive such distribution. Notwithstanding the
         foregoing, in the event that the Company shall distribute rights or
         warrants (other than those referred to in subsection (b) above)
         ("RIGHTS") pro rata to holders of Common Stock, the Company may, in
         lieu of making any adjustment pursuant to this Section 5.06, make
         proper provision so that each Holder of a Note who converts such Note
         (or any portion thereof) after the record date for such distribution
         and prior to the expiration or redemption of the Rights shall be
         entitled to receive upon such conversion, in addition to the shares of
         Common Stock issuable upon such conversion (the "CONVERSION SHARES"), a
         number of Rights to be determined as follows: (i) if such conversion
         occurs on or prior to the date for the distribution to the holders of
         Rights of separate certificates evidencing such Rights (the
         "DISTRIBUTION DATE"), the same number of Rights to which a holder of a
         number of shares of Common Stock equal to the number of Conversion
         Shares is entitled at the time of such conversion in accordance with
         the terms and provisions of and applicable to the Rights; and (ii) if
         such conversion occurs after the Distribution Date, the same number of
         Rights to which a holder of the number of shares of Common Stock into
         which the principal amount of the Note so converted was convertible
         immediately prior to the Distribution Date would have been entitled on
         the Distribution Date in accordance with the terms and provisions of
         and applicable to the Rights.

                  (d) In case the Company shall, by dividend or otherwise, at
         any time distribute to all holders of its Common Stock cash (including
         any distributions of cash out of current or retained earnings of the
         Company but excluding any cash that is distributed as part of a
         distribution requiring a Conversion Price adjustment pursuant to
         paragraph (c) of this Section 5.06) in an aggregate amount that,
         together with the sum of (x) the aggregate amount of any other
         distributions to all holders of its Common Stock made in cash plus (y)
         all Excess Payments, in each case made within the 12 months preceding
         the date fixed for determining the stockholders entitled to such
         distribution (the "DISTRIBUTION RECORD DATE") and in respect of which
         no Conversion Price adjustment pursuant to paragraphs (c) or (e) of
         this Section 5.06 or this paragraph (d) has been made, exceeds 15% of
         the product of the current market price per share (determined as
         provided in paragraph (f) of this Section 5.06) of the Common Stock on
         the Distribution Record Date times the number of shares of Common Stock
         outstanding on the Distribution Record Date (excluding shares held in
         the treasury of the Company), the Conversion Price shall be reduced so
         that the same shall equal the price determined by multiplying such
         Conversion Price in effect immediately prior to the effectiveness of
         the Conversion Price reduction contemplated by this paragraph (d) by a
         fraction of which the numerator shall be the current market price per
         share (determined as provided in paragraph (f) of this Section 5.06) of
         the Common Stock on the Distribution Record Date less the amount of
         such cash and other consideration (including any Excess Payments) so
         distributed applicable to one share (based on the pro rata portion of
         the aggregate amount of such cash and other consideration (including
         any Excess Payments), divided by the shares of Common Stock outstanding
         on the Distribution Record Date) of Common Stock and the denominator
         shall be such current market price per share (determined as provided in
         paragraph (f) of this Section 5.06) of the Common Stock on the
         Distribution



                                       30
<PAGE>   35

         Record Date, such reduction to become effective immediately prior to
         the opening of business on the day following the Distribution Record
         Date.

                  (e) In case a tender offer or other negotiated transaction
         made by the Company or any Subsidiary for all or any portion of the
         Common Stock shall be consummated, if an Excess Payment is made in
         respect of such tender offer or other negotiated transaction and the
         amount of such Excess Payment, together with the sum of (x) the
         aggregate amount of all Excess Payments plus (y) the aggregate amount
         of all distributions to all holders of the Common Stock made in cash
         (specifically including distributions of cash out of retained
         earnings), in each case made within the 12 months preceding the date of
         payment of such current negotiated transaction consideration or
         expiration of such current tender offer, as the case may be (the
         "PURCHASE DATE"), and as to which no adjustment pursuant to paragraph
         (c) or paragraph (d) of this Section 5.06 or this paragraph (e) has
         been made, exceeds 15% of the product of the current market price per
         share (determined as provided in paragraph (f) of this Section 5.06) of
         the Common Stock on the Purchase Date times the number of shares of
         Common Stock outstanding (including any tendered shares but excluding
         any shares held in the treasury of the Company) on the Purchase Date,
         the Conversion Price shall be reduced so that the same shall equal the
         price determined by multiplying such Conversion Price in effect
         immediately prior to the effectiveness of the Conversion Price
         reduction contemplated by this paragraph (e) by a fraction of which the
         numerator shall be the current market price per share (determined as
         provided in paragraph (f) of this Section 5.06) of the Common Stock on
         the Purchase Date less the amount of such Excess Payments and such cash
         distributions, if any, applicable to one share (based on the pro rata
         portion of the aggregate amount of such Excess Payments and such cash
         distributions, divided by the shares of Common Stock outstanding on the
         Purchase Date) of Common Stock and the denominator shall be such
         current market price per share (determined as provided in paragraph (f)
         of this Section 5.06) of the Common Stock on the Purchase Date, such
         reduction to become effective immediately prior to the opening of
         business on the day following the Purchase Date.

                  (f) The current market price per share of Common Stock on any
         date shall be deemed to be the average of the Daily Market Prices for
         the shorter of (i) ten consecutive business days ending on the last
         full trading day on the exchange or market referred to in determining
         such Daily Market Prices prior to the time of determination or (ii) the
         period commencing on the date next succeeding the first public
         announcement of the issuance of such rights or such warrants or such
         other distribution or such negotiated transaction through such last
         full trading day on the exchange or market referred to in determining
         such Daily Market Prices prior to the time of determination.

                  (g) In any case in which this Section 5.06 shall require that
         an adjustment be made immediately following a record date, the Company
         may elect to defer (but only until five Business Days following the
         filing by the Company with the Trustee of the certificate described in
         Section 5.10 hereof) issuing to the Holder of any Note converted after
         such record date the shares of Common Stock and other Capital Stock of
         the Company issuable upon such conversion over and above the shares of
         Common Stock and other Capital Stock of the Company issuable upon such
         conversion only on the basis of the Conversion Price prior to
         adjustment; and, in lieu of the shares the issuance of which is so
         deferred, the Company shall



                                       31
<PAGE>   36

         issue or cause its transfer agents to issue due bills or other
         appropriate evidence of the right to receive such shares.

SECTION 5.07.     NO ADJUSTMENT.


                  No adjustment in the Conversion Price shall be required until
         cumulative adjustments amount to 1% or more of the Conversion Price as
         last adjusted; provided, however, that any adjustments which by reason
         of this Section 5.07 are not required to be made shall be carried
         forward and taken into account in any subsequent adjustment. All
         calculations under this Article V shall be made to the nearest cent or
         to the nearest one-hundredth of a share, as the case may be. No
         adjustment need be made for rights to purchase Common Stock pursuant to
         a Company plan for reinvestment of dividends or interest. No adjustment
         need be made for a change in the par value or no par value of the
         Common Stock.

SECTION 5.08.     OTHER ADJUSTMENTS.

                  (a) In the event that, as a result of an adjustment made
         pursuant to Section 5.06 hereof, the Holder of any Note thereafter
         surrendered for conversion shall become entitled to receive any shares
         of Capital Stock of the Company other than shares of its Common Stock,
         thereafter the Conversion Price of such other shares so receivable upon
         conversion of any Note shall be subject to adjustment from time to time
         in a manner and on terms as nearly equivalent as practicable to the
         provisions with respect to Common Stock contained in this Article V.

                  (b) In the event that shares of Common Stock are not delivered
         after the expiration of any of the rights or warrants referred to in
         Section 5.06(b) and Section 5.06(c) hereof, the Conversion Price shall
         be readjusted to the Conversion Price which would otherwise be in
         effect had the adjustment made upon the issuance of such rights or
         warrants been made on the basis of delivery of only the number of
         shares of Common Stock actually delivered.

SECTION 5.09.     ADJUSTMENTS FOR TAX PURPOSES.


                  The Company may make such reductions in the Conversion Price,
         in addition to those required by Section 5.06 hereof, as it determines
         to be advisable in order that any stock dividend, subdivision of
         shares, distribution or rights to purchase stock or securities or
         distribution of securities convertible into or exchangeable for stock
         made by the Company to its stockholders will not be taxable to the
         recipients thereof.

SECTION 5.10.     NOTICE OF ADJUSTMENT.


                  Whenever the Conversion Price is adjusted, the Company shall
         promptly mail to Holders at the addresses appearing on the Registrar's
         books a notice of the adjustment and file with the Trustee an Officers'
         Certificate briefly stating the facts requiring the adjustment and the
         manner of computing it. The certificate shall be conclusive evidence of
         the correctness of such adjustment. Unless and until a Trust Officer of
         the Trustee shall receive written notice of an adjustment of the
         Conversion Price, the Trustee may assume without inquiry that the
         Conversion Price has not been adjusted and that the last Conversion
         Price of which it has knowledge remains in effect.

SECTION 5.11.     NOTICE OF CERTAIN TRANSACTIONS.


                  In the event that:


                  (1) the Company takes any action which would require an
         adjustment in the Conversion Price;


                  (2) the Company takes any action that would require a
         supplemental indenture pursuant to Section 5.12; or


                  (3) there is a dissolution or liquidation of the Company;


         the Company shall mail to Holders at the addresses appearing on the
         Registrar's books and the Trustee a notice stating the proposed record
         or effective date, as the case may be, to permit a Holder of a Note to
         convert such Note into shares of Common Stock prior to the record date
         for or the effective date of the transaction in order to receive the
         rights, warrants, securities or assets which a Holder of shares of
         Common Stock on that date may receive. The Company shall mail the
         notice at least 15 days before such date; however, failure to mail such
         notice or any defect therein shall not affect the validity of any
         transaction referred to in clause (1), (2) or (3) of this Section 5.11.


SECTION 5.12.     EFFECT OF RECLASSIFICATIONS, CONSOLIDATIONS, MERGERS OR SALES
ON CONVERSION PRIVILEGE.


                  If any of the following shall occur, namely: (i) any
         reclassification or change of outstanding shares of Common Stock
         issuable upon conversion of Notes (other than a change in par value, or
         from par value to no par value, or from no par value to par value, or
         as a result of a subdivision or combination), (ii) any consolidation or
         merger to which the Company is a party other than a merger in which the
         Company is the continuing corporation and which does not result in any
         reclassification of, or change (other than a change in name, or par
         value, or from par value to no par value, or from no par value to par
         value or as a result of a subdivision or combination) in, outstanding
         shares of Common Stock or (iii) any sale or conveyance of all or
         substantially all of the property or business of the Company as an
         entirety, then the Company, or such successor or purchasing
         corporation, as the case may be, shall, as a condition precedent to
         such reclassification, change, consolidation, merger, sale or
         conveyance, execute and deliver to the Trustee a supplemental indenture
         in form reasonably satisfactory to the Trustee providing that the
         Holder of each Note then outstanding shall have the right to convert
         such Note into the kind and amount of shares of stock and other
         securities and property (including cash) receivable upon such
         reclassification, change, consolidation, merger, sale or conveyance by
         a holder of the number of shares of Common Stock deliverable upon
         conversion of such Note immediately prior to such reclassification,
         change, consolidation, merger, sale or conveyance. Such supplemental
         indenture shall provide for adjustments of the Conversion Price which
         shall be as nearly equivalent as may be practicable to the adjustments
         of the Conversion Price provided for in this Article V. The foregoing,
         however, shall not in any way affect the right a Holder of a Note may
         otherwise have, pursuant to clause (ii) of the last sentence of
         subsection (c) of Section 5.06 hereof, to receive Rights upon
         conversion of a Note. If in the case of any such consolidation, merger,
         sale or

                                       33
<PAGE>   38
         conveyance, the stock or other securities and property (including cash)
         receivable thereupon by a holder of Common Stock includes shares of
         stock or other securities and property of a corporation other than the
         successor or purchasing corporation, as the case may be, in such
         consolidation, merger, sale or conveyance, then such supplemental
         indenture shall also be executed by such other corporation and shall
         contain such additional provisions to protect the interests of the
         Holders of the Notes as the Board of Directors of the Company shall
         reasonably consider necessary by reason of the foregoing. The provision
         of this Section 5.12 shall similarly apply to successive
         consolidations, mergers, sales or conveyances.


                  In the event the Company shall execute a supplemental
         indenture pursuant to this Section 5.12, the Company shall promptly
         file with the Trustee an Officers' Certificate briefly stating the
         reasons therefor, the kind or amount of shares of stock or securities
         or property (including cash) receivable by Holders of the Notes upon
         the conversion of their Notes after any such reclassification, change,
         consolidation, merger, sale or conveyance and any adjustment to be made
         with respect thereto.

SECTION 5.13.     TRUSTEE'S DISCLAIMER.


                  The Trustee has no duty to determine when an adjustment under
         this Article V should be made, how it should be made or what such
         adjustment should be, but may accept as conclusive evidence of the
         correctness of any such adjustment, and shall be protected in relying
         upon the Officers' Certificate with respect thereto which the Company
         is obligated to file with the Trustee pursuant to Section 5.10 hereof.
         The Trustee makes no representation as to the validity or value of any
         securities or assets issued upon conversion of Notes, and the Trustee
         shall not be responsible for the Company's failure to comply with any
         provisions of this Article V.


                  The Trustee shall not be under any responsibility to determine
         the correctness of any provisions contained in any supplemental
         indenture executed pursuant to Section 5.12, but may accept as
         conclusive evidence of the correctness thereof, and shall be protected
         in relying upon, the Officers' Certificate with respect thereto which
         the Company is obligated to file with the Trustee pursuant to Section
         5.12 hereof.

                                   ARTICLE VI
                                  SUBORDINATION

SECTION 6.01.     AGREEMENT TO SUBORDINATE AND RANKING.


                  The Company, for itself and its successors, and each Holder,
         by its acceptance of Notes, agree that the payment of the principal of
         or interest on or any other amounts due on the Notes is subordinated in
         right of payment, to the extent and in the manner stated in this
         Article VI, to the prior payment in full of all existing and future
         Senior Debt. The Notes shall rank pari passu with, and shall not be
         senior in right of payment to such other Indebtedness of the Company
         whether outstanding on the date of this Indenture or hereafter created,
         incurred, issued or guaranteed by the Company, where the instrument
         creating or evidencing such Indebtedness expressly provides that such
         Indebtedness ranks pari passu with the Notes.

SECTION 6.02.     NO PAYMENT ON NOTES IF SENIOR DEBT IN DEFAULT.


                  Anything in this Indenture to the contrary notwithstanding, no
         payment on account of principal of or redemption of, interest on,
         Special Interest on, or other amounts due on the Notes, and no
         redemption, purchase, or other acquisition of the Notes, shall be made
         by or on behalf of the Company (i) unless full payment of amounts then
         due for principal and interest and of all other amounts then due on all
         Senior Debt has been made or duly provided for pursuant to the terms of
         the instrument governing such Senior Debt, (ii) if, at the time of such
         payment, redemption, purchase or other acquisition, or immediately
         after giving effect thereto, there shall exist under any Senior Debt,
         or any agreement pursuant to which any Senior Debt is issued, any
         Default, which Default shall have resulted in the full amount of such
         Senior Debt being declared due and payable or (iii) if, at the time of
         such payment, redemption, purchase or other acquisition, the Trustee
         shall have received written notice from any of the holders of
         Designated Senior Debt or such holder's representative (a "PAYMENT
         BLOCKAGE NOTICE") that there exists under such Designated Senior Debt,
         or any agreement pursuant to which such Designated Senior Debt is
         issued, any Default, permitting the holders thereof to declare any
         amounts of such Designated Senior Debt due and payable, but only for
         the period (the "PAYMENT BLOCKAGE PERIOD") commencing on the date of
         receipt of the Payment Blockage Notice and ending (unless earlier
         terminated by notice given to the Trustee by the holders of such
         Designated Senior Debt) on the earlier of (a) the date on which such
         Event of Default shall have been cured or waived or (b)180 days from
         the receipt of the Payment Blockage Notice. Upon termination of the
         Payment Blockage Period, payments on account of principal of or
         interest on the Notes (other than, subject to Section 6.03 hereof,
         amounts due and payable by reason of the acceleration of the maturity
         of the Notes) and redemptions, purchases or other acquisitions may be
         made by or on behalf of the Company. Notwithstanding anything herein to
         the contrary, (a) only one Payment Blockage Notice may be given during
         any period of 360 consecutive days with respect to the same Event of
         Default or any other Events of Default on the same issue of Designated
         Senior Debt existing or continuing at the time of such notice unless
         such Event of Default or such other Events of Default have been cured
         or waived for a period of not less than 90 consecutive days and (b) no
         new Payment Blockage Period may be commenced by the holder or holders
         of Designated Senior Debt or their representative or representatives
         during any period of 360 consecutive days unless all Events of Default
         which were the subject of the immediately preceding Payment Blockage
         Notice have been cured or waived.


                  In the event that, notwithstanding the provisions of this
         Section 6.02, payments are made by or on behalf of the Company in
         contravention of the provisions of this Section 6.02, such payments
         shall be held by the Trustee, any Paying Agent or the holders, as
         applicable, in trust for the benefit of, and shall be paid over to and
         delivered to, the holders of Senior Debt or their representative or the
         trustee under the indenture or other agreement (if any), pursuant to
         which any instruments evidencing any Senior Debt may have been issued
         (as to which the Trustee shall be entitled to request and rely upon
         written certification from such holders of Senior Debt or related
         trustees) for application to the payment of all Senior Debt ratably
         according to the aggregate amounts remaining unpaid to the extent
         necessary to pay all Senior Debt in full in accordance with the terms
         of such Senior Debt, after giving effect to any concurrent payment or
         distribution to or for the holders of Senior Debt.



                                       35
<PAGE>   40

                  The Company shall give prompt written notice to the Trustee
         and any Paying Agent of any default or event of default under any
         Senior Debt or under any agreement pursuant to which any Senior Debt
         may have been issued.

SECTION 6.03.     DISTRIBUTION ON ACCELERATION OF NOTES; DISSOLUTION AND
REORGANIZATION; SUBROGATION OF NOTES.

                  (a) If the Notes are declared due and payable because of the
         occurrence of an Event of Default, the Company or the Trustee shall
         give prompt written notice to the holders of all Senior Debt or to the
         trustee(s) for such Senior Debt (in each case to the extent known to
         the Trustee) of such acceleration. The Company may not pay the
         principal of or interest on or any other amounts due on the Notes until
         five days after such holders or trustee(s) of Senior Debt receive such
         notice and, thereafter, the Company may pay the principal of or
         interest on or any other amounts due on the Notes only if the
         provisions of this Article VI permit such payment.

                  (b) Upon (i) any acceleration of the principal amount due on
         the Notes because of an Event of Default or (ii) any distribution of
         assets of the Company upon any dissolution, winding up, liquidation or
         reorganization of the Company (whether in bankruptcy, insolvency or
         receivership proceedings or upon an assignment for the benefit of
         creditors or any other dissolution, winding up, liquidation or
         reorganization of the Company):

                           (1) the holders of all Senior Debt shall first be
                  entitled to receive payment in full of the principal thereof,
                  the interest thereon and any other amounts due thereon before
                  the Holders are entitled to receive payment on account of the
                  principal of or interest on or any other amounts due on the
                  Notes;

                           (2) any payment or distribution of assets of the
                  Company of any kind or character, whether in cash, property or
                  securities (other than securities of the Company as
                  reorganized or readjusted or securities of the Company or any
                  other corporation provided for by a plan of reorganization or
                  readjustment the payment of which is subordinate, at least to
                  the extent provided in this Article VI with respect to the
                  Notes, to the payment in full without diminution or
                  modification by such plan of all Senior Debt), to which the
                  Holders or the Trustee would be entitled except for the
                  provisions of this Article VI, shall be paid by the
                  liquidating trustee or agent or other Person making such a
                  payment or distribution, directly to the holders of Senior
                  Debt (or their representatives(s) or trustee(s) acting on
                  their behalf), ratably according to the aggregate amounts
                  remaining unpaid on account of the principal of or interest on
                  and other amounts due on the Senior Debt held or represented
                  by each, to the extent necessary to make payment in full of
                  all Senior Debt remaining unpaid, after giving effect to any
                  concurrent payment or distribution to the holders of such
                  Senior Debt; and

                           (3) in the event that, notwithstanding the foregoing,
                  any payment or distribution of assets of the Company of any
                  kind or character, whether in cash, property or securities
                  (other than securities of the Company as reorganized or
                  readjusted, or securities of the Company or any other
                  corporation provided for by a

<PAGE>   41

                  plan of reorganization or readjustment the payment of which is
                  subordinate, at least to the extent provided in this Article
                  VI with respect to the Notes, to the payment in full without
                  diminution or modification by such plan of Senior Debt), shall
                  be received by the Trustee or the Holders before all Senior
                  Debt is paid in full, such payment or distribution shall be
                  held in trust for the benefit of, and be paid over to upon
                  request by a holder of the Senior Debt, the holders of the
                  Senior Debt remaining unpaid (or their representatives) or
                  trustee(s) acting on their behalf, ratably as aforesaid, for
                  application to the payment of such Senior Debt until all such
                  Senior Debt shall have been paid in full, after giving effect
                  to any concurrent payment or distribution to the holders of
                  such Senior Debt. Subject to the payment in full of all Senior
                  Debt, the Holders shall be subrogated to the rights of the
                  holders of Senior Debt to receive payments or distributions of
                  cash, property or securities of the Company applicable to the
                  Senior Debt until the principal of and interest on the Notes
                  shall be paid in full and, for purposes of such subrogation,
                  no such payments or distributions to the holders of Senior
                  Debt of cash, property or securities which otherwise would
                  have been payable or distributable to Holders shall, as
                  between the Company, its creditors other than the holders of
                  Senior Debt, and the Holders, be deemed to be a payment by the
                  Company to or on account of the Senior Debt, it being
                  understood that the provisions of this Article VI are, and are
                  intended solely for the purpose of, defining the relative
                  rights of the Holders, on the one hand, and the holders of
                  Senior Debt, on the other hand.

                  Nothing contained in this Article VI or elsewhere in this
         Indenture or in the Notes is intended to or shall (i) impair, as
         between the Company and its creditors other than the holders of Senior
         Debt, the obligation of the Company, which is absolute and
         unconditional, to pay to the Holders the principal of and interest on
         the Notes as and when the same shall become due and payable in
         accordance with the terms of the Notes, or, (ii) affect the relative
         rights of the Holders and creditors of the Company other than holders
         of Senior Debt or, as between the Company and the Trustee, the
         obligations of the Company to the Trustee, or (iii) prevent the Trustee
         or the Holders from exercising all remedies otherwise permitted by
         applicable law upon default under this Indenture, subject to the
         rights, if any, under this Article VI of the holders of Senior Debt in
         respect of cash, property and securities of the Company received upon
         the exercise of any such remedy.


                  Upon distribution of assets of the Company referred to in this
         Article VI, the Trustee, subject to the provisions of Section 9.01
         hereof, and the Holders shall be entitled to rely upon a certificate of
         the liquidating trustee or agent or other Person making any
         distribution to the Trustee or to the Holders for the purpose of
         ascertaining the Persons entitled to participate in such distribution,
         the holders of the Senior Debt and other indebtedness of the Company,
         the amount thereof or payable thereon, the amount or amounts paid or
         distributed thereon and all other facts pertinent thereto or to this
         Article VI. The Trustee, however, shall not be deemed to owe any
         fiduciary duty to the holders of Senior Debt. Nothing contained in this
         Article VI or elsewhere in this Indenture, or in any of the Notes,
         shall prevent the good faith application by the Trustee of any moneys
         which were deposited with it hereunder, prior to its receipt of written
         notice of facts which would prohibit such application, for the purpose
         of the payment of or on account of the principal of or interest on, the
         Notes unless, prior to the date on which such application is made by
         the Trustee, the Trustee shall be charged with notice under Section
         6.03(d) hereof of the facts which would prohibit the making of such
         application.


                                       37
<PAGE>   42

                  (c) The provisions of this Article VI shall not be applicable
         to any cash, properties or securities received by the Trustee or by any
         Holder when received as a holder of Senior Debt and nothing in Section
         9.11 hereof or elsewhere in this Indenture shall deprive the Trustee or
         such Holder of any of its rights as such holder.

                  (d) The Company shall give prompt written notice to the
         Trustee of any fact known to the Company which would prohibit the
         making of any payment of money to or by the Trustee in respect of the
         Notes pursuant to the provisions of this Article VI. The Trustee,
         subject to the provisions of Section 9.01 hereof, shall be entitled to
         assume that no such fact exists unless the Company or any holder of
         Senior Debt or any trustee therefor has given such notice to the
         Trustee. Notwithstanding the provisions of this Article VI or any other
         provisions of this Indenture, the Trustee shall not be charged with
         knowledge of the existence of any fact which would prohibit the making
         of any payment of monies to or by the Trustee in respect of the Notes
         pursuant to the provisions in this Article VI, unless, and until three
         Business Days after, the Trustee shall have received written notice
         thereof from the Company or any holder or holders of Senior Debt or
         from any trustee therefor; and, prior to the receipt of any such
         written notice, the Trustee, subject to the provisions of Section 9.01
         hereof, shall be entitled in all respects conclusively to assume that
         no such facts exist; provided that if on a date not less than three
         Business Days immediately preceding the date upon which by the terms
         hereof any such monies may become payable for any purpose (including,
         without limitation, the principal of or interest on any Note), the
         Trustee shall not have received with respect to such monies the notice
         provided for in this Section 6.03(d), than anything herein contained to
         the contrary notwithstanding, the Trustee shall have full power and
         authority to receive such monies and to apply the same to the purpose
         for which they were received, and shall not be affected by any notice
         to the contrary which may be received by it on or after such prior
         date.


                  The Trustee shall be entitled to rely on the delivery to it of
         a written notice by a Person representing himself to be a holder of
         Senior Debt (or a trustee on behalf of such holder) to establish that
         such notice has been given by a holder of Senior Debt (or a trustee on
         behalf of any such holder or holders). In the event that the Trustee
         determines in good faith that further evidence is required with respect
         to the right of any Person as a holder of Senior Debt to participate in
         any payment or distribution pursuant to this Article VI, the Trustee
         may request such Person to furnish evidence to the reasonable
         satisfaction of the Trustee as to the amount of Senior Debt held by
         such Person, the extent to which such Person is entitled to participate
         in such payment or distribution and any other facts pertinent to the
         rights of such Person under this Article VI, and, if such evidence is
         not furnished, the Trustee may defer any payment to such Person pending
         judicial determination as to the right of such Person to receive such
         payment; nor shall the Trustee be charged with knowledge of the curing
         or waiving of any default of the character specified in Section 6.02
         hereof or that any event or any condition preventing any payment in
         respect of the Notes shall have ceased to exist, unless and until the
         Trustee shall have received an Officers' Certificate to such effect.

                  (e) The provisions of this Section 6.03 applicable to the
         Trustee shall also apply to any Paying Agent for the Company.

SECTION 6.04.     RELIANCE BY SENIOR DEBT ON SUBORDINATION PROVISIONS.



                                       38
<PAGE>   43

                  Each Holder of any Note by his acceptance thereof acknowledges
         and agrees that the foregoing subordination provisions are, and are
         intended to be, an inducement and a consideration for each holder of
         any Senior Debt, whether such Senior Debt was created or acquired
         before or after the issuance of the Notes, to acquire and continue to
         hold, or to continue to hold, such Senior Debt, and such holder of
         Senior Debt shall be deemed conclusively to have relied on such
         subordination provisions in acquiring and continuing to hold, or in
         continuing to hold, such Senior Debt. Notice of any default in the
         payment of any Senior Debt, except as expressly stated in this Article
         VI, and notice of acceptance of the provisions hereof are hereby
         expressly waived. Except as otherwise expressly provided herein, no
         waiver, forbearance or release by any holder of Senior Debt under such
         Senior Debt or under this Article VI shall constitute a release of any
         of the obligations or liabilities of the Trustee or Holders of the
         Notes provided in this Article VI.

SECTION 6.05.     NO WAIVER OF SUBORDINATION PROVISIONS.


                  Except as otherwise expressly provided herein, no right of any
         present or future holder of any Senior Debt to enforce subordination as
         herein provided shall at any time in any way be prejudiced or impaired
         by any act or failure to act on the part of the Company or by any act
         or failure to act, in good faith, by any such holder, or by any
         noncompliance by the Company with the terms, provisions and covenants
         of this Indenture, regardless of any knowledge thereof any such holder
         may have or be otherwise charged with.


                  Without in any way limiting the generality of the foregoing
         paragraph, the holders of Senior Debt may, at any time and from time to
         time, without the consent of, or notice to, the Trustee or the Holders
         of the Notes, without incurring responsibility to the Holders of the
         Notes and without impairing or releasing the subordination provided in
         this Article VI or the obligations hereunder of the Holders of the
         Notes to the holders of Senior Debt, do any one or more of the
         following: (i) change the manner, place or terms of payment of, or
         renew or alter, Senior Debt, or otherwise amend or supplement in any
         manner Senior Debt or any instrument evidencing the same or any
         agreement under which Senior Debt is outstanding; (ii) sell, exchange,
         release or otherwise dispose of any property pledged, mortgaged or
         otherwise securing Senior Debt; (iii) release any Person liable in any
         manner for the collection of Senior Debt; and (iv) exercise or refrain
         from exercising any rights against the Company or any other Person.

SECTION 6.06.     TRUSTEE'S RELATION TO SENIOR DEBT.


                  The Trustee in its individual capacity shall be entitled to
         all the rights set forth in this Article VI in respect of any Senior
         Debt at any time held by it, to the same extent as any holder of Senior
         Debt, and nothing in Section 9.11 hereof or elsewhere in this Indenture
         shall deprive the Trustee of any of its rights as such holder.


                  With respect to the holders of Senior Debt, the Trustee
         undertakes to perform or to observe only such of its covenants and
         obligation, as are specifically set forth in this Article VI, and no
         implied covenants or obligations with respect to the holders of Senior
         Debt shall be read into this Indenture against the Trustee. The Trustee
         shall not owe any fiduciary duty to the holders of Senior Debt but
         shall have only such obligations to such holders as are



                                       39

<PAGE>   44

         expressly set forth in this Article VI; and in no event shall the
         Trustee be liable to any such holders if it shall in good faith
         mistakenly pay over or distribute to Holders of the Notes or to the
         Company (or any other Person) amounts to which such holders of Senior
         Debt would be entitled under this Article.


                  Each Holder of a Note by his acceptance thereof authorizes and
         directs the Trustee on his behalf to take such action as may be
         necessary or appropriate to effectuate the subordination provided in
         this Article VI and appoints the Trustee his attorney-in-fact for any
         and all such purposes, including, in the event of any dissolution,
         winding up or liquidation or reorganization under any applicable
         bankruptcy law of the Company (whether in bankruptcy, insolvency or
         receivership proceedings or otherwise), the timely filing of a claim
         for the unpaid balance of such Holder's Notes in the form required in
         such proceedings and the causing of such claim to be approved. If the
         Trustee does not file a claim or proof of debt in the form required in
         such proceedings prior to 30 days before the expiration of the time to
         file such claims or proofs, then any Holder or holders of Senior Debt
         or their representative or representatives shall have the right to
         demand, sue for, collect, receive and receipt for the payments and
         distributions in respect of the Notes which are required to be paid or
         delivered to the holders of Senior Debt as provided in this Article VI
         and to file and prove all claims therefore and to take all such other
         action in the name of the holders or otherwise, as such holders of
         Senior Debt or representative thereof may determine to be necessary or
         appropriate for the enforcement of the provisions of this Article VI.

SECTION 6.07.     OTHER PROVISIONS SUBJECT HERETO.


                  Except as expressly stated in this Article VI, notwithstanding
         anything contained in this Indenture to the contrary, all the
         provisions of this Indenture and the Notes are subject to the
         provisions of this Article VI. However, nothing in this Article VI
         shall apply to or adversely affect the claims of, or payment, to, the
         Trustee pursuant to Section 9.07 hereof. Notwithstanding the foregoing,
         the failure to make a payment on account of principal of or interest on
         the Notes by reason of any provision of this Article VI shall not be
         construed as preventing the occurrence of an Event of Default under
         Section 8.01 hereof.

                                  ARTICLE VII
                                   SUCCESSORS

SECTION 7.01.     LIMITATION ON MERGER, SALE OR CONSOLIDATION.


                  The Company may not, directly or indirectly, consolidate with
         or merge with or into, or sell, lease or otherwise dispose of all or
         substantially all of its assets, on a consolidated basis, whether in a
         single transaction or a series of related transactions, to another
         person or group of affiliated persons, other than to its Wholly-Owned
         Subsidiaries, unless:

                  (a) either: (i) in the case of a merger or consolidation, the
         Company is the surviving entity; or (ii) the resulting, surviving or
         transferee entity is a corporation organized under the laws of the
         United States, any state thereof or the District of Columbia and
         expressly assumes by supplemental indenture all of the Company's
         obligations in connection with the Notes and the Indenture; and




                                       40
<PAGE>   45

                  (b) no Default or Event of Default shall exist immediately
         before or after giving effect on a pro forma basis to such transaction.


                  Upon any permitted consolidation or merger or any permitted
         sale, lease or other disposition of all or substantially all of the
         assets of the Company in accordance with the foregoing, the successor
         corporation formed by such consolidation or into which the Company is
         merged or to which such sale, lease or other disposition is made, shall
         succeed to, and be substituted for, and may exercise every right and
         power of, the Company under the Indenture with the same effect as if
         such successor corporation had been named therein in the same manner as
         the Company is named, and when a successor corporation duly assumes all
         of the obligations of the Company pursuant hereto and pursuant to the
         Notes, the Company will be released from its obligations under the
         Indenture and the Notes, except as to any obligations that arise from
         or as a result of such transaction.


                  For purposes of the foregoing, the transfer, by lease,
         assignment, sale or otherwise, of all or substantially all of the
         properties and assets of one or more Subsidiaries, which properties and
         assets, if held by the Company instead of such Subsidiary, would
         constitute all or substantially all of the Company's properties and
         assets, shall be deemed to be the transfer of all or substantially all
         of the Company's properties and assets. This Section 7.01 will not
         apply to a sale, assignment, transfer, conveyance or other disposition
         of assets between or among the Company and any of its Wholly-Owned
         Subsidiaries.

SECTION 7.02.     SUCCESSOR CORPORATION SUBSTITUTED.


                  Upon any consolidation or merger, or any sale, assignment,
         transfer, lease, conveyance or other disposition of all or
         substantially all of the assets of the Company undertaken in accordance
         with Section 7.01 hereof, the successor corporation formed by such
         consolidation or into or with which the Company is merged or to which
         such sale, assignment, transfer, lease, conveyance or other disposition
         is made shall succeed to, and be substituted for and may exercise every
         right and power of, the Company under this Indenture with the same
         effect as if such successor Person has been named as the Company
         herein.

                              DEFAULTS AND REMEDIES

SECTION 8.01.     EVENTS OF DEFAULT.


                  An "EVENT OF DEFAULT" occurs if:

                  (a) the Company defaults in the payment of interest on any
         Note when the same becomes due and payable and the Default continues
         for a period of 30 days after the date due and payable;

                  (b) the Company defaults in the payment of the principal of
         any Note when the same becomes due and payable at maturity, upon
         optional redemption, in connection with a Purchase Offer, upon
         declaration or otherwise;


                                       41
<PAGE>   46

                  (c) the Company fails to observe or perform for a period of 30
         days after notice any covenant or agreement contained in Sections 4.07
         and 7.01 hereof (other than, in the case of Section 4.07, a failure to
         purchase Notes in connection with a Purchase Offer) hereof;

                  (d) the Company fails to observe or perform any other covenant
         or agreement contained in this Indenture or the Notes, required by it
         to be performed and the failure continues for a period of 60 days after
         notice from the Trustee to the Company or from the Holders of 25% in
         aggregate principal amount of the then outstanding Notes to the Company
         and the Trustee stating that such notice is a "Notice of Default";

                  (e) the failure by the Company or any Significant Subsidiary
         to make any payment at final stated maturity, including any applicable
         grace period, in respect of its Indebtedness (other than non-recourse
         obligations) in an amount in excess of $15 million, and continuance of
         such failure for 30 days after written notice is given to the Company
         by the Trustee or to the Company and the Trustee by the Holders of at
         least 25% in aggregate principal amount of Notes outstanding.

                  (f) A default by the company or any Significant Subsidiary
         with respect to any of the Company's Indebtedness (other than
         non-recourse obligations), which default results in the acceleration of
         Indebtedness in an amount in excess of $15 million without such
         Indebtedness having been discharged or such acceleration having been
         rescinded or annulled for 30 days after written notice is given to the
         Company by the Trustee or to us and the Trustee by the Holders of at
         least 25% in aggregate principal amount or Notes outstanding.

                  (g) failure by the Company or any of its Subsidiaries that is
         a Significant Subsidiary or any group of two or more Subsidiaries that,
         taken as a whole, would constitute a Significant Subsidiary to pay
         final judgments for the payment of money (other than any judgment as to
         which a reputable insurance company has accepted liability subject to
         customary terms) aggregating in excess of $5.0 million, which judgments
         are not paid, discharged or stayed within 60 days after their entry;

                  (h) the Company or any of its Subsidiaries that is a
         Significant Subsidiary or any group of two or more Subsidiaries that,
         taken as a whole, would constitute a Significant Subsidiary pursuant to
         or within the meaning of any Bankruptcy Law:

                           (i) commences a voluntary case;

                           (ii) consents to the entry of an order for relief
                  against it in an involuntary case in which it is the debtor;

                           (iii) consents to the appointment of a Custodian of

                  become due; or

         (i) a court of competent jurisdiction enters an order or decree under
any Bankruptcy Law that:


                                       42

         Subsidiaries that is a Significant Subsidiary or any group of two or

         Significant Subsidiary in an involuntary case;

                  (ii) appoints a Custodian of the Company or any of its
         Subsidiaries that is a Significant Subsidiary or any group of two or

         Subsidiaries that is a Significant Subsidiary or any group of two or
         more Subsidiaries that, taken as a whole, would constitute a
         Significant Subsidiary, and the order or decree remains unstayed and in
         effect for 60 days.

         The term "BANKRUPTCY LAW" means Title 11, U.S. Code or any similar
Federal, state or foreign law for the relief of debtors or the protection of
creditors. The term "CUSTODIAN" means any receiver, trustee, assignee,
liquidator or similar official under any Bankruptcy Law.

SECTION 8.02.     ACCELERATION.


                  If an Event of Default (other than an Event of Default
         specified in clauses (g) or (h) of Section 8.01 hereof) occurs and is
         continuing, the Trustee by notice to the Company, or the Holders of at
         least 25% in principal amount of the then outstanding Notes by notice
         to the Company and the Trustee, may declare all the Notes to be due and
         payable. Upon such declaration, the principal of, premium, if any, and
         interest on the Notes shall be due and payable immediately. If an Event
         of Default specified in clause (g) or (h) of Section 8.01 hereof
         occurs, such an amount shall ipso facto become and be immediately due
         and payable without any declaration or other act on the part of the
         Trustee or any Holder.


                  If the Notes have been declared due and payable as a result of
         the acceleration of Indebtedness prior to its express maturity pursuant
         to Section 8.01(e)(ii), such declaration shall be automatically
         rescinded if the acceleration of such indebtedness has been rescinded
         or annulled within 30 days after such acceleration in accordance with
         the mortgage, indenture or instrument under which it was issued and if
         (i) the recission would not conflict with any judgment or decree of a
         court of competent jurisdiction and (ii) all existing Events of Default
         have been cured or waived except nonpayment of principal or interest on
         the Notes that has become due solely because of the acceleration of the
         Notes.


                  Except as otherwise provided in the immediately preceding
         paragraph, the Holders of a majority in principal amount of the then
         outstanding Notes by notice to the Trustee may rescind an acceleration
         and its consequences (i) if the recission would not conflict with any
         judgment or decree of a court of competent jurisdiction and (ii) if all
         existing Events of Default have been cured or waived except nonpayment
         of principal or interest on the Notes that has become due solely
         because of the acceleration of the Notes.

SECTION 8.03.     OTHER REMEDIES.


                                       43
<PAGE>   48

                  If an Event of Default occurs and is continuing, the Trustee
         may pursue any available remedy to collect the payment of principal or
         interest on the Notes or to enforce the performance of any provision of
         the Notes or this Indenture.


                  The Trustee may maintain a proceeding even if it does not
         possess any of the Notes or does not produce any of them in the
         proceeding. A delay or omission by the Trustee or any Holder in
         exercising any right or remedy accruing upon an Event of Default shall
         not impair the right or remedy or constitute a waiver of or
         acquiescence in the Event of Default. All remedies are cumulative to
         the extent permitted by law.

SECTION 8.04.     WAIVER OF PAST DEFAULTS.


                  The Holders of a majority in principal amount of the then
         outstanding Notes by notice to the Trustee may on behalf of all of the
         Holders of the Notes waive an existing Default or Event of Default and
         its consequences except a continuing Default or Event of Default in the
         payment of the principal of or interest on any Note. When a Default or
         Event of Default is waived, it is cured and ceases; but no such waiver
         shall extend to any subsequent or other Default or impair any right
         consequent thereon.

SECTION 8.05.     CONTROL BY MAJORITY.


                  The Holders of a majority in principal amount of the then
         outstanding Notes may direct the time, method and place of conducting
         any proceeding for any remedy available to the Trustee or exercising
         any trust or power conferred on it. However, the Trustee may refuse to
         follow any direction that conflicts with law or this Indenture, is
         unduly prejudicial to the rights of other Holders, or would involve the
         Trustee in personal liability.

SECTION 8.06.     LIMITATION ON SUITS.


                  A Holder may pursue a remedy with respect to this Indenture or
         the Notes only if:

                  (a) the Holder gives to the Trustee notice of a continuing
         Event of Default;

                  (b) the Holders of at least 25% in principal amount of the
         then outstanding Notes make a request to the Trustee to pursue the
         remedy;

                  (c) such Holder or Holders offer to the Trustee indemnity
         satisfactory to the Trustee against any loss, liability or expense;

                  (d) the Trustee does not comply with the request within 60
         days after receipt of the request and the offer of indemnity; and

                  (e) during such 60-day period the Holders of a majority in
         principal amount of the then outstanding Notes do not give the Trustee
         a direction inconsistent with the request.


                  A Holder may not use this Indenture to prejudice the rights of
         another Holder or to obtain a preference or priority over another
         Holder.

                                       44
<PAGE>   49

SECTION 8.07.     RIGHTS OF HOLDERS TO RECEIVE PAYMENT.


                  Notwithstanding any other provision of this Indenture, the
         right of any Holder of a Note to receive payment of principal, and
         interest on the Note, on or after the respective due dates expressed in
         the Note, or to bring suit for the enforcement of any such payment on
         or after such respective dates, shall not be impaired or affected
         without the consent of the Holder.

SECTION 8.08.     COLLECTION SUIT BY TRUSTEE.


                  If an Event of Default specified in Section 8.01(a) or (b),
         hereof occurs and is continuing, the Trustee may recover judgment in
         its own name and as trustee of an express trust against the Company for
         the whole amount of principal and interest remaining unpaid on the
         Notes and interest on overdue principal and interest and such further
         amount as shall be sufficient to cover the costs and, to the extent
         lawful, expenses of collection, including the reasonable compensation,
         expenses, disbursements and advances of the Trustee, its agents and
         counsel.

SECTION 8.09.     TRUSTEE MAY FILE PROOFS OF CLAIM.


                  The Trustee may file such proofs of claim and other papers or
         documents as may be necessary or advisable in order to have the claims
         of the Trustee and the Holders allowed in any judicial proceedings
         relative to the Company, its creditors or its property. Nothing
         contained herein shall be deemed to authorize the Trustee to authorize
         or consent to or accept or adopt on behalf of any Holder any plan of
         reorganization, arrangement, adjustment or composition affecting the
         Notes or the rights of any Holder thereof, or to authorize the Trustee
         to vote in respect of the claim of any Holder in any such proceeding.

SECTION 8.10.     PRIORITIES.


                  If the Trustee collects any money pursuant to this Article, it
         shall pay out the money in the following order:


                  First: to the Trustee for amounts due under Section 9.07
         hereof;


                  Second: to the holders of Senior Debt, if and to the extent
         required by Article VI;


                  Third: to Holders for amounts due and unpaid on the Notes for
         principal and interest (and Special Interest, if applicable), ratably,
         without preference or priority of any kind, according to the amounts
         due and payable on the Notes for principal and interest, respectively;
         and


                  Fourth: to the Company.


                  The Trustee may fix a record date and payment date for any
         payment to Holders made pursuant to this Section 8.10.

                  In any suit for the enforcement of any right or remedy under
         this Indenture or in any suit against the Trustee for any action taken
         or omitted by it as a Trustee, a court in its discretion may require
         the filing by any party litigant in the suit of an undertaking to pay
         the costs of the suit, and the court in its discretion may assess
         reasonable costs, including reasonable attorneys' fees, against any
         party litigant in the suit, having due regard to the merits and good
         faith of the claims or defenses made by the party litigant. This
         Section 8.11 does not apply to a suit by the Trustee, a suit by a
         Holder pursuant to Section 8.07 hereof, or a suit by Holders of more
         than 10% in principal amount of the then outstanding Notes.

                                   ARTICLE IX
                                     TRUSTEE

SECTION 9.01.     DUTIES OF TRUSTEE.

                  (a) If an Event of Default has occurred and is continuing, the
         Trustee shall exercise such of the rights and powers vested in it by
         this Indenture, and use the same degree of care and skill in their
         exercise, as a prudent man would exercise or use under the
         circumstances in the conduct of his own affairs.

                  (b) Except during the continuance of an Event of Default: (i)
         the Trustee need perform only those duties that are specifically set
         forth in this Indenture and no others and (ii) in the absence of bad
         faith on its part, the Trustee may conclusively rely, as to the truth
         of the statements and the correctness of the opinions expressed
         therein, upon certificates or opinions furnished to the Trustee and
         conforming to the requirements of this Indenture. However, the Trustee
         shall examine the certificates and opinions to determine whether or not
         they conform on their face to the requirements of this Indenture.

                  (c) The Trustee may not be relieved from liability for its own
         negligent action, its own negligent failure to act, or its own willful
         misconduct, except that: (i) this paragraph does not limit the effect
         of paragraph (b) of this Section 9.01; (ii) the Trustee shall not be
         liable for any error of judgment made in good faith by a Trust Officer,
         unless it is proved that the Trustee was negligent in ascertaining the
         pertinent facts and (iii) the Trustee shall not be liable with respect
         to any action it takes or omits to take in good faith in accordance
         with a direction received by it pursuant to Section 8.05 hereof.

                  (d) Every provision of this Indenture that in any way relates
         to the Trustee is subject to paragraphs (a), (b) and (c) of this
         Section 9.01.

                  (e) The Trustee may refuse to perform any duty or exercise any
         right or power (including, without limitation, as requested or directed
         by a Holder) unless it receives indemnity satisfactory to it against
         any loss, liability or expense.

                  (f) The Trustee shall not be liable for interest on any money
         received by it except as the Trustee may agree in writing with the
         Company. Money held in trust by the Trustee need not be segregated from
         other funds except to the extent required by law.

SECTION 9.02.     RIGHTS OF TRUSTEE.

                                       46
<PAGE>   51

                  (a) The Trustee may rely on any document believed by it to be
         genuine and to have been signed or presented by the proper Person. The
         Trustee need not investigate any fact or matter stated in the document.

                  (b) Before the Trustee acts or refrains from acting, it may
         require an Officers' Certificate or an Opinion of Counsel, or both. The
         Trustee shall not be liable for any action it takes or omits to take in
         good faith in reliance on such Officers' Certificate or Opinion of
         Counsel.

                  (c) The Trustee may act through agents and shall not be
         responsible for the misconduct or negligence of any agent appointed
         with due care.

                  (d) The Trustee shall not be liable for any action it takes or
         omits to take in good faith which it believes to be authorized or
         within its rights or powers.

                  (e) The Trustee shall not be charged with knowledge of any
         Event of Default under subsections (c), through (i) (and subsection (a)
         or (b) if the Trustee does not act as Paying Agent) of Section 8.01 or
         of the identity of any Significant Subsidiary or of any group of two or
         more Subsidiaries that, taken as a whole, would constitute a
         Significant Subsidiary unless either (1) a Trust Officer of the Trustee
         assigned to its corporate trust department shall have actual knowledge
         thereof, or (2) the Trustee shall have received written notice thereof
         in accordance with Section 12.02 hereof from the Company or any Holder.

                  (f) The grant of any permissive rights, power or authority
         hereunder to the Trustee shall not be construed to be a duty.

SECTION 9.03.     INDIVIDUAL RIGHTS OF TRUSTEE.


                  The Trustee in its individual or any other capacity may become
         the owner or pledgee of Notes and may otherwise deal with the Company
         or an Affiliate with the same rights it would have if it were not
         Trustee. Any Agent may do the same with like rights. However, the
         Trustee is subject to Sections 9.10 and 9.11 hereof.

SECTION 9.04.     TRUSTEE'S DISCLAIMER.


                  The Trustee makes no representation as to the validity or
         adequacy of this Indenture or the Notes, it shall not be accountable
         for the Company's use of the proceeds from the Notes, and it shall not
         be responsible for any statement of the Company in the Indenture or any
         statement in the Notes other than its authentication or for compliance
         by the Company with the Registration Rights Agreement.

SECTION 9.05.     NOTICE OF DEFAULTS.


                  If a Default or Event of Default occurs and is continuing and
         if it is known to the Trustee, the Trustee shall mail to Holders a
         notice of the Default or Event of Default within 90 days after it
         occurs. Except in the case of a Default or Event of Default in payment
         on any Note, the Trustee may withhold the notice if and so long as a
         committee of its Trust Officers in good faith determines that
         withholding the notice is in the interests of Holders.

                                       47
<PAGE>   52
SECTION 9.06.  REPORTS BY TRUSTEE TO HOLDERS.

                  Within 60 days after the reporting date stated in Section
         12.10, the Trustee shall mail to Holders a brief report dated as of
         such reporting date that complies with TIA Section 313(a) if and to the
         extent required by such Section 313(a). The Trustee also shall comply
         with TIA Section 313(b)(2). The Trustee shall also transmit by mail all
         reports as required by TIA Section 313(c).

                  A copy of each report at the time of its mailing to Holders
         shall be filed with the SEC and each stock exchange on which the Notes
         are listed. The Company shall notify the Trustee when the Notes are
         listed on any stock exchange.

SECTION 9.07.  COMPENSATION AND INDEMNITY.

                  The Company shall pay to the Trustee from time to time
         reasonable compensation for its services hereunder as to which the
         Company and the Trustee shall from time to time mutually agree in
         writing. The Trustee's compensation shall not be limited by any law on
         compensation of a trustee of an express trust. The Company shall
         reimburse the Trustee upon request for all reasonable disbursements,
         expenses and advances incurred or made by it. Such disbursements and
         expenses may include the reasonable disbursements, compensation and
         expenses of the Trustee's agents and counsel.

                  The Company shall indemnify the Trustee against any claims,
         demands, expenses (including but not limited to reasonable
         compensation, fees, disbursements and expenses of the Trustee's agents
         and counsel), losses, damages or liabilities incurred by it, except as
         set forth in the next paragraph, arising out of, related to, or in
         connection with the acceptance or administration of this trust and its
         rights or duties hereunder, including the reasonable costs and
         expenses, and the costs and expenses of enforcing this Indenture
         (including this Section 9.07) against the Company and of defending
         itself against any claim (whether asserted by the Company, or any
         Holder or any other person) or liability in connection with the
         exercise or performance of any of its powers or duties hereunder. The
         Trustee shall notify the Company promptly of any claim for which it may
         seek indemnity. The Company shall defend the claim and the Trustee
         shall cooperate in the defense. The Trustee may have separate counsel
         and the Company shall pay the reasonable fees, disbursements and
         expenses of such counsel. The Company need not pay for any settlement
         made without its consent, which consent shall not be unreasonably
         withheld.

                  The Company need not reimburse any expense or indemnify
         against any loss or liability incurred by the Trustee through the
         Trustee's negligence or bad faith.

                  To secure the Company's payment obligations in this Section
         9.07, the Trustee shall have a lien prior to the Notes on all money or
         property held or collected by the Trustee, except money or property
         held in trust to pay principal and interest on particular Notes.

                  Without prejudice to any other rights available to the Trustee
         under applicable law, when the Trustee incurs expenses or renders
         services after an Event of Default specified in Section 8.01(h) or (i)
         hereof occurs, the expenses and the compensation for the services are
         intended to constitute expenses of administration under any Bankruptcy
         Law.

                                       48
<PAGE>   53
                  All amounts owing to the Trustee under this Section 9.07 shall
         be payable by the Company in United States dollars.

SECTION 9.08.  REPLACEMENT OF TRUSTEE.

                  A resignation or removal of the Trustee and appointment of a
         successor Trustee shall become effective only upon the successor
         Trustee's acceptance of appointment as provided in this Section 9.08.

                  The Trustee may resign by so notifying the Company. The
         Holders of a majority in principal amount of the then outstanding Notes
         may remove the Trustee by so notifying the Trustee and the Company. The
         Company may remove the Trustee if:

                  (a) the Trustee fails to comply with Section 9.10 hereof,
         unless the Trustee's duty to resign is stayed as provided in TIA
         Section 310(b);

                  (b) the Trustee is adjudged a bankrupt or an insolvent or an
         order for relief is entered with respect to the Trustee under any
         Bankruptcy Law;

                  (c) a Custodian or public officer takes charge of the Trustee
         or its property; or

                  (d) the Trustee becomes incapable of acting.

                  If the Trustee resigns or is removed or if a vacancy exists in
         the office of Trustee for any reason, the Company shall promptly
         appoint a successor Trustee. Within one year after the successor
         Trustee takes office, the Holders of a majority in principal amount of
         the then outstanding Notes may appoint a successor Trustee to replace
         the successor Trustee appointed by the Company.

                  If a successor Trustee does not take office within 60 days
         after the retiring Trustee resigns or is removed, the retiring Trustee,
         the Company or the Holders of at least 10% in principal amount of the
         then outstanding Notes may petition any court of competent jurisdiction
         for the appointment of a successor Trustee.

                  If the Trustee fails to comply with Section 9.10 hereof,
         unless the Trustee's duty to resign is stayed as provided in TIA
         Section 310(b), any Holder who has been a bona fide Holder of a Note
         for at least six months may petition any court of competent
         jurisdiction for the removal of the Trustee and the appointment of a
         successor Trustee.

                  A successor Trustee shall deliver a written acceptance of its
         appointment to the retiring Trustee and to the Company. Thereupon the
         resignation or removal of the retiring Trustee shall become effective,
         and the successor Trustee shall have all the rights, powers and duties
         of the Trustee under this Indenture. The successor Trustee shall mail a
         notice of its succession to Holders. The retiring Trustee shall
         promptly transfer all property held by it as Trustee to the successor
         Trustee, subject to the lien provided for in Section 9.07 hereof.
         Notwithstanding replacement of the Trustee pursuant to this Section
         9.08 hereof, the Company's obligations under Section 9.07 hereof shall
         continue for the benefit of the retiring trustee with respect to
         expenses and liabilities incurred by it prior to such replacement.

SECTION 9.09.  SUCCESSOR TRUSTEE BY MERGER, ETC.

                  If the Trustee consolidates, merges or converts into, or
         transfers all or substantially all of its corporate trust business
         (including the administration of this Indenture) to, another
         corporation, the successor corporation without any further act shall be
         the successor Trustee.

SECTION 9.10.  ELIGIBILITY; DISQUALIFICATION.

                  This Indenture shall always have a Trustee who satisfies the
         requirements of TIA Section 310(a)(1) and (5). The Trustee shall always
         have a combined capital and surplus as stated in Section 12.10 hereof.
         The Trustee is subject to TIA Section 310(b).

SECTION 9.11.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

                  The Trustee is subject to TIA Section 311(a), excluding any
         creditor relationship listed in TIA Section 311(b). A Trustee who has
         resigned or been removed shall be subject to TIA Section 311(a) to the
         extent indicated therein.

SECTION 10.01.  TERMINATION OF COMPANY'S OBLIGATIONS.

                  This Indenture shall cease to be of further effect (except
         that the Company's obligations under Sections 9.07 and 10.02 hereof
         shall survive) when all outstanding Notes theretofore authenticated and
         issued have been delivered to the Trustee for cancellation and the
         Company has paid all sums payable hereunder.

SECTION 10.02.  REPAYMENT TO COMPANY.

                  The Trustee and the Paying Agent shall promptly pay to the
         Company upon request any excess money or securities held by them at any
         time.

                  The Trustee and the Paying Agent shall pay to the Company upon
         request any money held by them for the payment of principal or interest
         that remains unclaimed for two years after the date upon which such
         payment shall have become due (subject to the requirements of any
         abandoned property laws that may be applicable); provided, however,
         that the Company shall have first caused notice of such payment to the
         Company to be mailed to each Holder entitled thereto no less than 30
         days prior to such payment. After payment to the Company, the Trustee
         and the Paying Agent shall have no further liability with respect to
         such money and Holders entitled to the money must look to the Company
         for payment as general creditors unless any applicable abandoned
         property law designates another Person.

<PAGE>   55
                  The Company and the Trustee may amend or supplement this
Indenture or the Notes without the consent of any Holder:

                  (a) to cure any ambiguity, defect or inconsistency;

                  (b) to comply with Sections 5.12 and 7.01 hereof;

                  (c) to provide for uncertificated Notes in addition to or in
         place of certificated Notes;

                  (d) to make any change that provides additional rights or
         benefits to the Holders of the Notes;

                  (e) to make any change that does not adversely affect the
         interests hereunder of any Holder; or

                  (f) to qualify the Indenture under the TIA or to comply with
         the requirements of the SEC in order to maintain the qualification of
         the Indenture under the TIA.

SECTION 11.02.  WITH CONSENT OF HOLDERS.

                  Subject to Section 8.07 hereof, the Company and the Trustee
         may amend or supplement this Indenture or the Notes with the written
         consent of the Holders of at least a majority in principal amount of
         the then outstanding Notes. Subject to Sections 8.04 and 8.07 hereof,
         the Holders of a majority in principal amount of the Notes then
         outstanding may also waive compliance in a particular instance by the
         Company with any provision of this Indenture or the Notes. However,
         without the consent of each Holder affected, an amendment, supplement
         or waiver under this Section 11.02 may not:

                  (a) reduce the principal amount of Notes whose Holders must
         consent to an amendment, supplement or waiver;

                  (b) reduce the principal of or change the fixed maturity of
         any Note or alter the provisions of Section 7 of the Notes in a manner
         adverse to the Holders;

                  (c) reduce the rate of or change the time for payment or
         accrual of interest on any Note;

                  (d) waive a continuing default or Event of Default in the
         payment of the principal of or interest on any Note, except a
         rescission of acceleration of the Notes by the Holders of at least a
         majority in aggregate principal amount of the Notes and a waiver of the
         payment default that resulted from such acceleration;

                  (e) make any Note payable in money other than that stated in
         the Note;

                  (f) make any change in Section 8.04 or 8.07 hereof;

                  (g) waive a redemption payment with respect to any Note;

                  (i) modify Article V or VI in a manner adverse to the Holders
         of Notes; and

                  (j) make any change in the foregoing amendment and waiver
         provisions of this Article XI.

                  To secure a consent of the Holders under this Section 11.02,
         it shall not be necessary for the Holders to approve the particular
         form of any proposed amendment, supplement or waiver, but it shall be
         sufficient if such consent approves the substance thereof.

                  After an amendment, supplement or waiver under this Section
         11.02 becomes effective, the Company shall mail to Holders a notice
         briefly describing the amendment or waiver.

SECTION 11.03.  COMPLIANCE WITH TRUST INDENTURE ACT.

                  Every amendment to this Indenture or the Notes shall be set
         forth in a supplemental indenture that complies with the TIA as then in
         effect.

SECTION 11.04.  REVOCATION AND EFFECT OF CONSENTS.

                  Until an amendment, supplement or waiver becomes effective, a
         consent to it by a Holder of a Note is a continuing consent by the
         Holder and every subsequent Holder of a Note or portion of a Note that
         evidences the same debt as the consenting Holder's Note, even if
         notation of the consent is not made on any Note. However, any such
         Holder or subsequent Holder may revoke the consent as to his Note or
         portion of a Note if the Trustee receives the notice of revocation
         before the date on which the Trustee receives an Officers' Certificate
         certifying that the Holders of the requisite principal amount of Notes
         have consented to the amendment, supplement or waiver.

                  The Company may, but shall not be obligated to, fix a record
         date for the purpose of determining the Holders entitled to consent to
         any amendment, supplement or waiver. If a record date is fixed, then
         notwithstanding the provisions of the immediately preceding paragraph,
         those Persons who were Holders at such record date (or their duly
         designated proxies), and only those Persons, shall be entitled to
         consent to such amendment, supplement or waiver or to revoke any
         consent previously given, whether or not such Persons continue to be
         Holders after such record date. No consent shall be valid or effective
         for more than 90 days after such record date unless consents from
         Holders of the principal amount of Notes required hereunder for such
         amendment or waiver to be effective shall have also been given and not
         revoked within such 90-day period.

                  After an amendment, supplement or waiver becomes effective it
         shall bind every Holder, unless it is of the type described in any of
         clauses (a) through (j) of Section 11.02 hereof. In such case, the
         amendment or waiver shall bind each Holder who has consented to it and
         every subsequent Holder that evidences the same debt as the consenting
         Holder's Note.

SECTION 11.05.  NOTATION ON OR EXCHANGE OF NOTES.

                                       52
<PAGE>   57
                  The Trustee may place an appropriate notation about an
         amendment or waiver on any Note thereafter authenticated. The Company
         in exchange for all Notes may issue and the Trustee shall authenticate
         new Notes that reflect the amendment or waiver.

                  Failure to make such notation on a Note or to issue a new Note
         as aforesaid shall not affect the validity and effect of such amendment
         or waiver.

SECTION 11.06.  TRUSTEE PROTECTED.

                  The Trustee shall sign all supplemental indentures, except
         that the Trustee may, but need not, sign any supplemental indenture
         that adversely affects its rights, obligations or protections. Upon
         request by the Company to sign any amendment or supplement, the Trustee
         shall be entitled to request and receive from the Company, and to rely
         upon, an Opinion of Counsel and Officer's Certificate to the effect
         that such supplement or amendment is authorized or permitted under this
         Article XI.

                                   ARTICLE XII
                                  MISCELLANEOUS

SECTION 12.01.  TRUST INDENTURE ACT CONTROLS.

                  This Indenture is subject to the provisions of the TIA that
         are required to be incorporated into this Indenture (or, prior to the
         registration of the Notes pursuant to the Registration Rights
         Agreement, would be required to be incorporated into this Indenture if
         it were qualified under the TIA), and shall, to the extent applicable,
         be governed by such provisions. If any provision of this Indenture
         limits, qualifies, or conflicts with another provision which is
         required (or would be so required) to be incorporated in this Indenture
         by the TIA, the incorporated provision shall control.

SECTION 12.02.  NOTICES.

                  Any notice or communication by the Company or the Trustee to
         the other is duly given if in writing and delivered in Person or mailed
         by first class mail to the other's address stated in Section 12.10
         hereof. The Company or the Trustee by notice to the other may designate
         additional or different addresses for subsequent notices or
         communications.

                  Any notice or communication to a Holder shall be mailed by
         first class mail to his address shown on the register kept by the
         Registrar. Failure to mail a notice or communication to a Holder or any
         defect in it shall not affect its sufficiency with respect to other
         Holders.

                  If a notice or communication is mailed in the manner provided
         above within the time prescribed, it is duly given, whether or not the
         addressee receives it.

                  If the Company mails a notice or communication to Holders, it
         shall mail a copy to the Trustee and each Agent at the same time.

                  All other notices or communications shall be in writing.

                                       53
<PAGE>   58
                  In case by reason of the suspension of regular mail service,
         or by reason of any other cause, it shall be impossible to mail any
         notice as required by the Indenture, then such method of notification
         as shall be made with the approval of the Trustee shall constitute a
         sufficient mailing of such notice.

SECTION 12.03.  COMMUNICATION BY HOLDERS WITH OTHER HOLDERS.

                  Holders may communicate pursuant to TIA Section 312(b) with
         other Holders with respect to their rights under this Indenture or the
         Notes. The Company, the Trustee, the Registrar and anyone else shall
         have the protection of TIA Section 312(c).

SECTION 12.04.  CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT.

                  Upon any request or application by the Company to the Trustee
         to take any action under this Indenture, the Company shall furnish to
         the Trustee:

                  (a) an Officers' Certificate stating that, in the opinion of
         the signers, all conditions precedent, if any, provided for in this
         Indenture relating to the proposed action have been complied with; and

                  (b) an Opinion of Counsel stating that, in the opinion of such
         counsel, all such conditions precedent have been complied with.

SECTION 12.05.  STATEMENTS REQUIRED IN CERTIFICATE OR OPINION.

                  Each certificate or opinion with respect to compliance with a
         condition or covenant provided for in this Indenture (other than
         pursuant to Section 4.03) shall include:

                  (a) a statement that the Person signing such certificate or
         rendering such opinion has read such covenant or condition;

                  (b) a brief statement as to the nature and scope of the
         examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

                  (c) a statement that, in the opinion of such Person, such
         Person has made such examination or investigation as is necessary to
         enable such Person to express an informed opinion as to whether or not
         such covenant or condition has been complied with; and

                  (d) a statement as to whether or not, in the opinion of such
         Person, such condition or covenant has been complied with.

SECTION 12.06.  RULES BY TRUSTEE AND AGENTS.

                  The Trustee may make reasonable rules for action by, or a
         meeting of, Holders. The Registrar or Paying Agent may make reasonable
         rules and set reasonable requirements for its functions.

SECTION 12.07.  LEGAL HOLIDAYS.

                                       54
<PAGE>   59
                  A "LEGAL HOLIDAY" is a Saturday, a Sunday or a day on which
         banking institutions in the State of New York are not required to be
         open. If a payment date is a Legal Holiday at a place of payment,
         payment may be made at that place on the next succeeding day that is
         not a Legal Holiday, and no interest shall accrue for the intervening
         period. If any other operative date for purposes of this Indenture
         shall occur on a Legal Holiday then for all purposes the next
         succeeding day that is not a Legal Holiday shall be such operative
         date.

SECTION 12.08.  NO RECOURSE AGAINST OTHERS.

                  A director, officer, employee, incorporator or shareholder of
         the Company, as such, shall not have any liability for any Obligations
         of the Company under the Notes or this Indenture or for any claim based
         on, in respect of or by reason of such Obligations or their creation.
         Each Holder by accepting a Note waives and releases all such liability.
         The waiver and release are part of the consideration for the issue of
         the Notes.

SECTION 12.09.  COUNTERPARTS AND FACSIMILE SIGNATURES.

                  This Indenture may be executed by manual or facsimile
         signature in any number of counterparts and by the parties hereto in
         separate counterparts, each of which when so executed shall be deemed
         to be an original and all of which taken together shall constitute one
         and the same agreement.

SECTION 12.11.  GOVERNING LAW, SUBMISSION TO JURISDICTION.


                  THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN THIS
         INDENTURE AND THE NOTES, WITHOUT REGARD TO THE CONFLICT OF LAWS
         PROVISIONS THEREOF.

                  To the extent permitted by applicable law, the Company
         irrevocably submits to the nonexclusive jurisdiction of any federal or
         state court in the Borough of Manhattan, City and State of New York,
         United States of America, in any suit or proceeding based on or arising
         under this Indenture and the Notes and irrevocably agrees that all
         claims in respect of such suit or proceeding may be determined in any
         such court. The Company irrevocably and fully waives the defense of an
         inconvenient forum to the maintenance of such suit or proceeding. The
         Company hereby irrevocably designates and appoints CT Corporation
         System as the authorized agent of the Company upon whom process may be
         served in any such suit or proceeding (the "PROCESS AGENT"), it being
         understood that the designation and appointment of the Process Agent as
         such authorized agent shall become effective immediately without any
         further action on the part of the Company. The Company represents to
         the Trustee that it has notified the Process Agent of such designation
         and appointment and that the Process Agent has accepted the same. The
         Company hereby irrevocably authorizes and directs the Process Agent to
         accept such service. The Company further agrees that service of process
         upon the Process Agent shall be deemed in every respect effective
         service of process upon the Company in any such suit or proceeding.
         Nothing herein shall affect the right of the Trustee or any Holder to
         serve process in any other manner permitted by law. In the event that
         CT Corporation System ceases to be the Process Agent, the Company
         agrees that it will take any and all action, including the execution
         and filing of any and all such documents and instruments as may be
         necessary to validly designate and appoint an alternate agent as
         Process Agent, and to maintain such designation and appointment in full
         force and effect so long as the Company has any outstanding obligations
         under this Indenture or the Notes, on terms that are reasonably
         acceptable to the Trustee. To the extent that the Company has or
         hereafter may acquire any immunity from jurisdiction of any court or
         from any legal process (whether through service of notice, attachment
         prior to judgment, attachment in aid of execution, execution or
         otherwise) with respect to itself or its property, the Company hereby
         irrevocably waives such immunity in respect of its obligations
         hereunder and thereunder, to the extent permitted by law.

SECTION 12.12.  NO ADVERSE INTERPRETATION OF OTHER AGREEMENTS.

                  This Indenture may not be used to interpret another indenture,
         loan or debt agreement of the Company or an Affiliate. Any such
         indenture, loan or debt agreement may not be used to interpret this
         Indenture.

SECTION 12.13.  SUCCESSORS.

                  All agreements of the Company in this Indenture and the Notes
         shall bind its successor. All agreements of the Trustee in this
         Indenture shall bind its successor.

SECTION 12.14.  SEVERABILITY.

                  In case any provision in this Indenture or in the Notes shall
         be invalid, illegal or unenforceable, the validity, legality and
         enforceability of the remaining provisions shall not in any way be
         affected or impaired thereby.

SECTION 12.15.  TABLE OF CONTENTS, HEADINGS, ETC.

                  The Table of Contents, Cross-Reference Table, and headings of
         the Articles and Sections of this Indenture have been inserted for
         convenience of reference only, are not to be considered a part hereof,
         and shall in no way modify or restrict any of the terms or provisions
         hereof.

                 5 -1/2% CONVERTIBLE SUBORDINATED NOTE DUE 2007

                              RULE 144A GLOBAL NOTE

         1. INTEREST. AKAMAI TECHNOLOGIES, INC., a Delaware corporation (the
"COMPANY"), is the issuer of 5 -1/2% Convertible Subordinated Notes due 2007
(the "Notes"). The Notes will accrue interest at a rate of 5 -1/2% per annum.
The Company promises to pay interest on the Notes in cash semiannually on each
July 1 and January 1, commencing on January 1, 2001, to Holders of record on the
immediately preceding June 15 and December 15, respectively. Interest on the
Notes will accrue from the most recent date to which interest has been paid, or
if no interest has been paid, from June 20, 2000. Interest will be computed on
the basis of a 360-day year of twelve 30-day months. The Company will pay
interest on overdue principal at the interest rate borne by the Notes,
compounded semiannually, and, to the extent permitted by law, it shall pay
interest on overdue installments of interest (without regard to any applicable
grace period) at the same interest rate compounded semiannually.

         2. REGISTRATION RIGHTS. The holder of this Note (and the Common Stock
issuable upon conversion hereof) is entitled to the benefits of a Registration
Rights Agreement, dated as of June 20, 2000, among the Company and the Initial
Purchasers (the "REGISTRATION RIGHTS AGREEMENT"). Pursuant to the Registration
Rights Agreement the Company has agreed for the benefit of the holders of
Transfer Restricted Securities, that (i) it will, at its cost, within 90 days
after the closing of the sale of the Notes (the "CLOSING"), file a shelf
registration statement (the "SHELF REGISTRATION STATEMENT") with the Securities
and Exchange Commission (the "COMMISSION") with respect to resales of the Notes
and the Common Stock issuable upon conversion thereof, (ii) it will use its
reasonable best efforts to cause such Shelf Registration Statement to be
declared effective within 180 days after the Closing, and (iii) it will use its
reasonable best efforts to keep such Shelf Registration Statement continuously
effective under the Securities Act, subject to certain exceptions specified in
the Registration Rights Agreement, until the second anniversary of the date of
the Closing. If (a) the Company fails to file the Shelf Registration Statement
required by the Registration Rights Agreement on or before the date specified
above for such filing, (b) such Shelf Registration Statement is not declared
effective by the Commission on or prior to the date specified above for such
effectiveness, or (c) the Shelf Registration Statement is declared effective but
thereafter ceases to be effective or useable in connection with resales of
Transfer Restricted Securities during the periods specified in the Registration
Rights Agreement without being succeeded immediately by a post-effective
amendment to such Shelf Registration Statement that cures such failure and is
itself declared effective immediately (each such event referred to in clauses
(a) through (c) above a "REGISTRATION DEFAULT"), then the Company will pay
special interest to each Holder of Transfer Restricted Securities as described
below. Notwithstanding the foregoing, as set forth in the Registration Rights
Agreement, the Company will be permitted to suspend use of the prospectus that
is part of the Shelf Registration Statement during certain periods of time and
in certain circumstances relating to pending corporate developments and public
filings with the SEC and similar events, and such a suspension shall not be
deemed a Registration Default provided it does not last in excess of 60 days in
the aggregate during any 12-month period. With respect to the first 90-day
period immediately following the occurrence of a Registration Default, the
Company shall pay special interest to each Holder of Transfer Restricted
Securities in an amount equal to an increase in the annual interest rate on the
Notes of 0.25%

                                      A-5
<PAGE>   68
("SPECIAL INTEREST") and with respect to each subsequent 90-day period,
additional amounts equal to an increase in the annual interest rate on the Notes
of 0.25% until all Registration Defaults have been cured, up to a maximum
increase in the annual interest rate on the Notes equal to 1.0%. In the event
that this Note, or any portion thereof, shall have been converted into shares of
Common Stock pursuant to Section 12 hereof, the amount payable under this
Section 2 per share of Common Stock so converted shall be determined by dividing
(x) the amount that would have been payable hereunder on the aggregate principal
amount so converted by (y) the number of shares of Common Stock issued upon such
conversion. All accrued Special Interest shall be paid by the Company on each
Interest Payment Date for which Special Interest is owed to the holders of
Transfer Restricted Securities by wire transfer of immediately available funds
or by federal funds check. Following the cure of all Registration Defaults, the
application of Special Interest will cease. THE PROVISIONS OF THIS SECTION 2
SHALL SURVIVE ANY CONVERSION OF THE NOTES INTO SHARES OF COMMON STOCK PURSUANT
TO SECTION 12 HEREOF, AND MAY BE ENFORCED BY THE HOLDER OF COMMON STOCK ISSUED
UPON CONVERSION OF THIS NOTE.

         3. PAYMENTS. All payments made by the Company on this Note shall be
made without deduction or withholding for or on account of, any and all present
or future taxes, duties, assessments, or governmental charges of whatever nature
unless the deduction or withholding of such taxes, duties, assessments or
government charges is then required by law.

         4. METHOD OF PAYMENT. The Company will pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders of Notes
at the close of business on the record date for the next interest payment date
even though Notes are canceled after the record date and on or before the
interest payment date. Holders must surrender Notes to a Paying Agent to collect
principal and premium payments. The Company will pay principal, premium, if any,
interest, and Special Interest, if any, in money of the United States that at
the time of payment is legal tender for payment of public and private debts.
However, the Company may pay principal, premium, if any, interest and Special
Interest, if any, by check payable in such money. It may mail an interest or
Special Interest check to a Holder's registered address. Upon the request of a
Holder who holds an aggregate principal amount of at least $5.0 million,
principal, premium, if any, interest, and Special Interest, if any, shall be
paid by wire transfer of immediately available funds to an account previously
specified in writing by such Holder to the Company and the Trustee.

         5. PAYING AGENT, CONVERSION AGENT AND REGISTRAR. The Trustee will act
as Paying Agent, Conversion Agent and Registrar and will maintain an office or
agency in the City of New York, New York at which the notes may be presented for
payment, transfer or exchange. The Company may change any Paying Agent,
Conversion Agent or Registrar without prior notice. The Company or any of its
Affiliates may act in any such capacity.

         6. INDENTURE. The Company issued the Notes under an Indenture, dated as
of June 20, 2000 (the "INDENTURE"), between the Company and State Street Bank
and Trust Company, as Trustee. Capitalized terms herein are used as defined in
the Indenture unless otherwise defined herein. The terms of the Notes include
those stated in the Indenture and those made part of the Indenture by the Trust
Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the "TIA") as in
effect on the date of the Indenture. The Notes are subject to, and qualified by,
all such terms, certain of which are summarized hereon, and Holders are referred
to the Indenture and such Act for a statement of such terms. The Notes are
unsecured general obligations of the Company limited to

                                      A-6
<PAGE>   69
$300,000,000 in aggregate principal amount and subordinated in right of payment
to all existing and future Senior Debt of the Company.

         7. REDEMPTION. At any time on or after July 3, 2003 the Company may
redeem any portion of the Notes, in whole or in part, upon not less than 30 nor
more than 60 days' notice, at the redemption prices (expressed as percentages of
principal amount thereof), together with accrued and unpaid interest and Special
Interest thereon to, but excluding, the applicable redemption date. If redeemed
during the period beginning July 3, 2003 and ending on June 30, 2004, the
redemption price shall be 103.143%, and if redeemed during the 12-month period
commencing on July 1 of each of the following years, up to the maturity date the
redemption price shall be the corresponding percentage of principal set forth
below:

<TABLE>
<CAPTION>
         Period                                                              Redemption Price
         ------                                                              ----------------
<S>                                                                          <C>
         July 1, 2004 - June 30, 2005 .........................................  102.357%
         July 1, 2005 - June 30, 2006 .........................................  101.571%
         July 1, 2006 - June 30, 2007 .........................................  100.786%
         July 1, 2007 .........................................................  100.000%
</TABLE>

         In the event the Company redeems less than all of the outstanding
Notes, the Notes to be redeemed shall be selected by the Trustee in accordance
with Section 3.02 of the Indenture. In the event a portion of an outstanding
Note is selected for redemption and such Note is converted in part after such
selection, the converted portion of such Note shall be deemed (so far as may be)
to be the portion to be selected for redemption in accordance with Section 3.02
of the Indenture. The Company may not give notice of any redemption if the
Company has defaulted in payment of interest and the default is continuing.

         8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least
30 days but not more than 60 days before the redemption date to each Holder of
the Notes to be redeemed at his address of record. The Notes in denominations
larger than $1,000 may be redeemed in part but only in integral multiples of
$1,000. In the event of a redemption of less than all of the Notes, the Notes
will be chosen for redemption by the Trustee in accordance with the Indenture.
On and after the redemption date, interest ceases to accrue on the Notes or
portions of them called for redemption.

         If this Note is redeemed subsequent to a record date with respect to
any interest payment date specified above and on or prior to such interest
payment date, then any accrued interest will be paid to the Person in whose name
this Note is registered at the close of business on such record date.

         9. MANDATORY REDEMPTION. The Company will not be required to make
mandatory redemption or repurchase payments with respect to the Notes. There are
no sinking fund payments with respect to the Notes.

         10. REPURCHASE AT OPTION OF HOLDER. If there is a Fundamental Change,
the Company shall be required to offer to purchase on the Purchase Date all
outstanding Notes at a purchase price equal to 100% of the aggregate principal
amount thereof, plus accrued and unpaid interest and Special Interest, if any,
to the Purchase Date. Holders of Notes that are subject to an offer to purchase
will receive a Fundamental Change Offer from the Company in accordance with

                                      A-7
<PAGE>   70
Section 3.09 of the Indenture and may elect to have such Notes or portions
thereof in authorized denominations purchased by completing the form entitled
"Option of Holder to Elect Purchase" appearing below.

         11. SUBORDINATION. The payment of the principal of, interest on,
Special Interest or any other amounts due on the Notes is subordinated in right
of payment to all existing and future Senior Debt of the Company, as described
in the Indenture. Each Holder, by accepting a Note, agrees to such subordination
and authorizes and directs the Trustee on its behalf to take such action as may
be necessary or appropriate to effectuate the subordination so provided and
appoints the Trustee as its attorney-in-fact for such purpose.

         12. CONVERSION. The holder of any Note has the right, exercisable at
any time following the Issuance Date and prior to the close of business (New
York time) on the date of the Note's maturity, to convert the principal amount
thereof (or any portion thereof that is an integral multiple of $1,000) into
shares of Common Stock at the initial Conversion Price of $115.47 per share,
subject to adjustment under certain circumstances as set forth in the Indenture,
except that if a Note is called for redemption, the conversion right will
terminate at the close of business on the Business Day immediately preceding the
date fixed for redemption.

         To convert a Note, a holder must (1) complete and sign a conversion
notice substantially in the form set forth below, (2) surrender the Note to a
Conversion Agent, (3) furnish appropriate endorsements or transfer documents if
required by the Registrar or Conversion Agent and (4) pay any transfer or
similar tax, if required. No payment or adjustment will be made for accrued and
unpaid interest on a converted Note, but if any holder surrenders a Note for
conversion after the close of business on the record date for the payment of an
installment of interest and prior to the opening of business on the next
interest payment date, then, notwithstanding such conversion, the interest
payable on such interest payment date shall be paid to the holder of such Note
on such record date. Any Notes that are, however, delivered to the Company for
conversion after any record date but before the next interest payment date must,
except as described in the next sentence, be accompanied by a payment equal to
the interest payable on such interest payment date on the principal amount of
such Notes being converted. Payments to the Company described in the preceding
sentence shall not be required if, during that period between a record date and
the next interest payment date, a conversion occurs on or after the date that
the Company has issued a redemption notice and prior to the date of redemption
stated in such notice. If any Notes are converted after an interest payment date
but on or before the next record date, no interest will be paid on those Notes.
The number of shares issuable upon conversion of a Note is determined by
dividing the principal amount of the Note converted by the Conversion Price in
effect on the Conversion Date. No fractional shares will be issued upon
conversion but a cash adjustment will be made for any fractional interest.

         A note in respect of which a holder has delivered an "Option of Holder
to Elect Purchase" form appearing below exercising the option of such holder to
require the Company to purchase such Note may be converted only if the notice of
exercise is withdrawn as provided above and in accordance with the terms of the
Indenture. The above description of conversion of the Notes is qualified by
reference to, and is subject in its entirety by, the more complete description
thereof contained in the Indenture.

                                      A-8
<PAGE>   71
         13. DENOMINATIONS, TRANSFER, EXCHANGE. The notes are in registered
form, without coupons, in denominations of $1,000 and integral multiples of
$1,000. The transfer of Notes may be registered, and Notes may be exchanged, as
provided in the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
any taxes and fees required by law or permitted by the Indenture. The Registrar
need not exchange or register the transfer of any Note or portion of a Note
selected for redemption (except the unredeemed portion of any Note being
redeemed in part). Also, it need not exchange or register the transfer of any
Note for a period of 15 days before a selection of Notes to be redeemed.

         14. PERSONS DEEMED OWNERS. The registered Holder of a Note may be
treated as its owner for all purposes.

         15. UNCLAIMED MONEY. If money for the payment of principal or interest
remains unclaimed for two years, the Trustee and the Paying Agent shall pay the
money back to the Company at its written request. After that, Holders of Notes
entitled to the money must look to the Company for payment unless an abandoned
property law designates another Person and all liability of the Trustee and such
Paying Agent with respect to such money shall cease.

         16. DEFAULTS AND REMEDIES. The Notes shall have the Events of Default
set forth in Section 8.01 of the Indenture. Subject to certain limitations in
the Indenture, if an Event of Default occurs and is continuing, the Trustee by
notice to the Company or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes by notice to the Company and the Trustee
may declare all the Notes to be due and payable immediately, except that in the
case of an Event of Default arising from certain events of bankruptcy,
insolvency or reorganization, all unpaid principal and interest accrued on the
Notes shall become due and payable immediately without further action or notice.
The Holders of a majority in principal amount of the Notes then outstanding by
written notice to the Trustee may rescind an acceleration and its consequences
if the rescission would not conflict with any judgment or decree and if all
existing Events of Default have been cured or waived except nonpayment of
principal or interest that has become due solely because of the acceleration.
Holders may not enforce the Indenture or the Notes except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in principal
amount of the then outstanding Notes issued under the Indenture may direct the
Trustee in its exercise of any trust or power. The Company must furnish annually
compliance certificates to the Trustee. The above description of Events of
Default and remedies is qualified by reference, and subject in its entirety, to
the more complete description thereof contained in the Indenture.

         17. AMENDMENTS, SUPPLEMENTS AND WAIVERS. Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Notes (including consents obtained in connection with a tender offer or exchange
offer for Notes), and any existing default may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes. Without
the consent of any Holder, the Indenture or the Notes may be amended, among
other reasons, to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for assumption of the Company's obligations to Holders, to make any
change that does not adversely affect the rights of any Holder or to qualify the
Indenture under the TIA or to comply with the requirements of the SEC in order
to maintain the qualification of the Indenture under the TIA.

                                      A-9
<PAGE>   72
         18. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee, in its individual
or any other capacity may become the owner or pledgee of the Notes and may
otherwise deal with the Company or an Affiliate with the same rights it would
have, as if it were not Trustee, subject to certain limitations provided for in
the Indenture and in the TIA. Any Agent may do the same with like rights.

         19. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or shareholder of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture or
for any claim based on, in respect of or by reason of such obligations or their
creation. Each Holder of the Notes by accepting a Note waives and releases all
such liability. The waiver and release are part of the consideration for the
issue of the Notes.

         20. GOVERNING LAW. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL
GOVERN THE INDENTURE AND THE NOTES WITHOUT REGARD TO CONFLICT OF LAW PROVISIONS
THEREOF.

         21. AUTHENTICATION. The Notes shall not be valid until authenticated by
the manual signature of an authorized officer of the Trustee or an
authenticating agent.

         22. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and UGMA (= Uniform Gifts to
Minors Act).

         The Company will furnish to any Holder of the Notes upon written
request and without charge a copy of the Indenture. Request may be made to:

                 5 -1/2% CONVERTIBLE SUBORDINATED NOTE DUE 2007

                            REGULATION S GLOBAL NOTE

         1. INTEREST. AKAMAI TECHNOLOGIES, INC., a Delaware corporation (the
"COMPANY"), is the issuer of 5 -1/2% Convertible Subordinated Notes due 2007
(the "Notes"). The Notes will accrue interest at a rate of 5 -1/2% per annum.
The Company promises to pay interest on the Notes in cash semiannually on each
July 1 and January 1, commencing on January 1, 2001, to Holders of record on the
immediately preceding June 15 and December 15, respectively. Interest on the
Notes will accrue from the most recent date to which interest has been paid, or
if no interest has been paid, from June 20, 2000. Interest will be computed on
the basis of a 360-day year of twelve 30-day months. The Company will pay
interest on overdue principal at the interest rate borne by the Notes,
compounded semiannually, and, to the extent permitted by law, it shall pay
interest on overdue installments of interest (without regard to any applicable
grace period) at the same interest rate compounded semiannually.

         2. REGISTRATION RIGHTS. The holder of this Note (and the Common Stock
issuable upon conversion hereof) is entitled to the benefits of a Registration
Rights Agreement, dated as of June 20, 2000, among the Company and the Initial
Purchasers (the "REGISTRATION RIGHTS AGREEMENT"). Pursuant to the Registration
Rights Agreement the Company has agreed for the benefit of the holders of
Transfer Restricted Securities, that (i) it will, at its cost, within 90 days
after the closing of the sale of the Notes (the "CLOSING"), file a shelf
registration statement (the "SHELF REGISTRATION STATEMENT") with the Securities
and Exchange Commission (the "COMMISSION") with respect to resales of the Notes
and the Common Stock issuable upon conversion thereof, (ii) it will use its
reasonable best efforts to cause such Shelf Registration Statement to be
declared effective within 180 days after the Closing, and (iii) it will use its
reasonable best efforts to keep such Shelf Registration Statement continuously
effective under the Securities Act, subject to certain exceptions specified in
the Registration Rights Agreement, until the second anniversary of the date of
the Closing. If (a) the Company fails to file the Shelf Registration Statement
required by the Registration Rights Agreement on or before the date specified
above for such filing, (b) such Shelf Registration Statement is not declared
effective by the Commission on or prior to the date specified above for such
effectiveness, or (c) the Shelf Registration Statement is declared effective but
thereafter ceases to be effective or useable in connection with resales of
Transfer Restricted Securities during the periods specified in the Registration
Rights Agreement without being succeeded immediately by a post-effective
amendment to such Shelf Registration Statement that cures such failure and is
itself declared effective immediately (each such event referred to in clauses
(a) through (c) above a "REGISTRATION DEFAULT"), then the Company will pay
special interest to each Holder of Transfer Restricted Securities as described
below. Notwithstanding the foregoing, as set forth in the Registration Rights
Agreement, the Company will be permitted to suspend use of the prospectus that
is part of the Shelf Registration Statement during certain periods of time and
in certain circumstances relating to pending corporate developments and public
filings with the SEC and similar events, and such a suspension shall not be
deemed a Registration Default provided it does not last in excess of 60 days in
the aggregate during any 12-month period. With respect to the first 90-day
period immediately following the occurrence of a Registration Default, the
Company shall pay special interest to each Holder of Transfer Restricted
Securities in an amount equal to an increase in the annual interest rate on the
Notes of 0.25%

                                      A-20
<PAGE>   83
("SPECIAL INTEREST") and with respect to each subsequent 90-day period,
additional amounts equal to an increase in the annual interest rate on the Notes
of 0.25% until all Registration Defaults have been cured, up to a maximum
increase in the annual interest rate on the Notes equal to 1.0%. In the event
that this Note, or any portion thereof, shall have been converted into shares of
Common Stock pursuant to Section 12 hereof, the amount payable under this
Section 2 per share of Common Stock so converted shall be determined by dividing
(x) the amount that would have been payable hereunder on the aggregate principal
amount so converted by (y) the number of shares of Common Stock issued upon such
conversion. All accrued Special Interest shall be paid by the Company on each
Interest Payment Date for which Special Interest is owed to the holders of
Transfer Restricted Securities by wire transfer of immediately available funds
or by federal funds check. Following the cure of all Registration Defaults, the
application of Special Interest will cease. THE PROVISIONS OF THIS SECTION 2
SHALL SURVIVE ANY CONVERSION OF THE NOTES INTO SHARES OF COMMON STOCK PURSUANT
TO SECTION 12 HEREOF, AND MAY BE ENFORCED BY THE HOLDER OF COMMON STOCK ISSUED
UPON CONVERSION OF THIS NOTE.

         3. PAYMENTS. All payments made by the Company on this Note shall be
made without deduction or withholding for or on account of, any and all present
or future taxes, duties, assessments, or governmental charges of whatever nature
unless the deduction or withholding of such taxes, duties, assessments or
government charges is then required by law.

         4. METHOD OF PAYMENT. The Company will pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders of Notes
at the close of business on the record date for the next interest payment date
even though Notes are canceled after the record date and on or before the
interest payment date. Holders must surrender Notes to a Paying Agent to collect
principal and premium payments. The Company will pay principal, premium, if any,
interest, and Special Interest, if any, in money of the United States that at
the time of payment is legal tender for payment of public and private debts.
However, the Company may pay principal, premium, if any, interest and Special
Interest, if any, by check payable in such money. It may mail an interest or
Special Interest check to a Holder's registered address. Upon the request of a
Holder who holds an aggregate principal amount of at least $5.0 million,
principal, premium, if any, interest, and Special Interest, if any, shall be
paid by wire transfer of immediately available funds to an account previously
specified in writing by such Holder to the Company and the Trustee.

         5. PAYING AGENT, CONVERSION AGENT AND REGISTRAR. The Trustee will act
as Paying Agent, Conversion Agent and Registrar and will maintain an office or
agency in the City of New York, New York at which the notes may be presented for
payment, transfer or exchange. The Company may change any Paying Agent,
Conversion Agent or Registrar without prior notice. The Company or any of its
Affiliates may act in any such capacity.

         6. INDENTURE. The Company issued the Notes under an Indenture, dated as
of June 20, 2000 (the "INDENTURE"), between the Company and State Street Bank
and Trust Company, as Trustee. Capitalized terms herein are used as defined in
the Indenture unless otherwise defined herein. The terms of the Notes include
those stated in the Indenture and those made part of the Indenture by the Trust
Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the "TIA") as in
effect on the date of the Indenture. The Notes are subject to, and qualified by,
all such terms, certain of which are summarized hereon, and Holders are referred
to the Indenture and such Act for a statement of such terms. The Notes are
unsecured general obligations of the Company limited to

                                      A-21
<PAGE>   84
$300,000,000 in aggregate principal amount and subordinated in right of payment
to all existing and future Senior Debt of the Company.

7. REDEMPTION. At any time on or after July 3, 2003 the Company may redeem any
portion of the Notes, in whole or in part, upon not less than 30 nor more than
60 days' notice, at the redemption prices (expressed as percentages of principal
amount thereof), together with accrued and unpaid interest and Special Interest
thereon to, but excluding, the applicable redemption date. If redeemed during
the period beginning July 3, 2003 and ending on June 30, 2004, the redemption
price shall be 103.143%, and if redeemed during the 12-month period commencing
on July 1 of each of the following years, up to the maturity date the redemption
price shall be the corresponding percentage of principal set forth below:

<TABLE>
         Period                                                                 Redemption Price
         ------                                                                 ----------------
<S>                                                                                <C>
         July 1, 2004 - June 30, 2005. ..........................................  102.357%
         July 1, 2005 - June 30, 2006. ..........................................  101.571%
         July 1, 2006 - June 30, 2007. ..........................................  100.786%
         July 1, 2007 . .........................................................  100.000%
</TABLE>

         In the event the Company redeems less than all of the outstanding
Notes, the Notes to be redeemed shall be selected by the Trustee in accordance
with Section 3.02 of the Indenture. In the event a portion of an outstanding
Note is selected for redemption and such Note is converted in part after such
selection, the converted portion of such Note shall be deemed (so far as may be)
to be the portion to be selected for redemption in accordance with Section 3.02
of the Indenture. The Company may not give notice of any redemption if the
Company has defaulted in payment of interest and the default is continuing.

         8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least
30 days but not more than 60 days before the redemption date to each Holder of
the Notes to be redeemed at his address of record. The Notes in denominations
larger than $1,000 may be redeemed in part but only in integral multiples of
$1,000. In the event of a redemption of less than all of the Notes, the Notes
will be chosen for redemption by the Trustee in accordance with the Indenture.
On and after the redemption date, interest ceases to accrue on the Notes or
portions of them called for redemption.

         If this Note is redeemed subsequent to a record date with respect to
any interest payment date specified above and on or prior to such interest
payment date, then any accrued interest will be paid to the Person in whose name
this Note is registered at the close of business on such record date.

         9. MANDATORY REDEMPTION. The Company will not be required to make
mandatory redemption or repurchase payments with respect to the Notes. There are
no sinking fund payments with respect to the Notes.

         10. REPURCHASE AT OPTION OF HOLDER. If there is a Fundamental Change,
the Company shall be required to offer to purchase on the Purchase Date all
outstanding Notes at a purchase price equal to 100% of the aggregate principal
amount thereof, plus accrued and unpaid interest and Special Interest, if any,
to the Purchase Date. Holders of Notes that are subject to an offer to purchase
will receive a Fundamental Change Offer from the Company in accordance with

                                      A-22
<PAGE>   85
Section 3.09 of the Indenture and may elect to have such Notes or portions
thereof in authorized denominations purchased by completing the form entitled
"Option of Holder to Elect Purchase" appearing below.

         11. SUBORDINATION. The payment of the principal of, interest on,
Special Interest or any other amounts due on the Notes is subordinated in right
of payment to all existing and future Senior Debt of the Company, as described
in the Indenture. Each Holder, by accepting a Note, agrees to such subordination
and authorizes and directs the Trustee on its behalf to take such action as may
be necessary or appropriate to effectuate the subordination so provided and
appoints the Trustee as its attorney-in-fact for such purpose.

         12. CONVERSION. The holder of any Note has the right, exercisable at
any time following the Issuance Date and prior to the close of business (New
York time) on the date of the Note's maturity, to convert the principal amount
thereof (or any portion thereof that is an integral multiple of $1,000) into
shares of Common Stock at the initial Conversion Price of $115.47 per share,
subject to adjustment under certain circumstances as set forth in the Indenture,
except that if a Note is called for redemption, the conversion right will
terminate at the close of business on the Business Day immediately preceding the
date fixed for redemption.

         To convert a Note, a holder must (1) complete and sign a conversion
notice substantially in the form set forth below, (2) surrender the Note to a
Conversion Agent, (3) furnish appropriate endorsements or transfer documents if
required by the Registrar or Conversion Agent and (4) pay any transfer or
similar tax, if required. No payment or adjustment will be made for accrued and
unpaid interest on a converted Note, but if any holder surrenders a Note for
conversion after the close of business on the record date for the payment of an
installment of interest and prior to the opening of business on the next
interest payment date, then, notwithstanding such conversion, the interest
payable on such interest payment date shall be paid to the holder of such Note
on such record date. Any Notes that are, however, delivered to the Company for
conversion after any record date but before the next interest payment date must,
except as described in the next sentence, be accompanied by a payment equal to
the interest payable on such interest payment date on the principal amount of
such Notes being converted. Payments to the Company described in the preceding
sentence shall not be required if, during that period between a record date and
the next interest payment date, a conversion occurs on or after the date that
the Company has issued a redemption notice and prior to the date of redemption
stated in such notice. If any Notes are converted after an interest payment date
but on or before the next record date, no interest will be paid on those Notes.
The number of shares issuable upon conversion of a Note is determined by
dividing the principal amount of the Note converted by the Conversion Price in
effect on the Conversion Date. No fractional shares will be issued upon
conversion but a cash adjustment will be made for any fractional interest.

         A note in respect of which a holder has delivered an "Option of Holder
to Elect Purchase" form appearing below exercising the option of such holder to
require the Company to purchase such Note may be converted only if the notice of
exercise is withdrawn as provided above and in accordance with the terms of the
Indenture. The above description of conversion of the Notes is qualified by
reference to, and is subject in its entirety by, the more complete description
thereof contained in the Indenture.

         13. DENOMINATIONS, TRANSFER, EXCHANGE. The notes are in registered
form, without coupons, in denominations of $1,000 and integral multiples of
$1,000. The transfer of Notes may be registered, and Notes may be exchanged, as
provided in the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
any taxes and fees required by law or permitted by the Indenture. The Registrar
need not exchange or register the transfer of any Note or portion of a Note
selected for redemption (except the unredeemed portion of any Note being
redeemed in part). Also, it need not exchange or register the transfer of any
Note for a period of 15 days before a selection of Notes to be redeemed.

         14. PERSONS DEEMED OWNERS. The registered Holder of a Note may be
treated as its owner for all purposes.

         15. UNCLAIMED MONEY. If money for the payment of principal or interest
remains unclaimed for two years, the Trustee and the Paying Agent shall pay the
money back to the Company at its written request. After that, Holders of Notes
entitled to the money must look to the Company for payment unless an abandoned
property law designates another Person and all liability of the Trustee and such
Paying Agent with respect to such money shall cease.

         16. DEFAULTS AND REMEDIES. The Notes shall have the Events of Default
set forth in Section 8.01 of the Indenture. Subject to certain limitations in
the Indenture, if an Event of Default occurs and is continuing, the Trustee by
notice to the Company or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes by notice to the Company and the Trustee
may declare all the Notes to be due and payable immediately, except that in the
case of an Event of Default arising from certain events of bankruptcy,
insolvency or reorganization, all unpaid principal and interest accrued on the
Notes shall become due and payable immediately without further action or notice.
The Holders of a majority in principal amount of the Notes then outstanding by
written notice to the Trustee may rescind an acceleration and its consequences
if the rescission would not conflict with any judgment or decree and if all
existing Events of Default have been cured or waived except nonpayment of
principal or interest that has become due solely because of the acceleration.
Holders may not enforce the Indenture or the Notes except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in principal
amount of the then outstanding Notes issued under the Indenture may direct the
Trustee in its exercise of any trust or power. The Company must furnish annually
compliance certificates to the Trustee. The above description of Events of
Default and remedies is qualified by reference, and subject in its entirety, to
the more complete description thereof contained in the Indenture.

         17. AMENDMENTS, SUPPLEMENTS AND WAIVERS. Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Notes (including consents obtained in connection with a tender offer or exchange
offer for Notes), and any existing default may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes. Without
the consent of any Holder, the Indenture or the Notes may be amended, among
other reasons, to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for assumption of the Company's obligations to Holders, to make any
change that does not adversely affect the rights of any Holder or to qualify the
Indenture under the TIA or to comply with the requirements of the SEC in order
to maintain the qualification of the Indenture under the TIA.

         18. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee, in its individual
or any other capacity may become the owner or pledgee of the Notes and may
otherwise deal with the Company or an Affiliate with the same rights it would
have, as if it were not Trustee, subject to certain limitations provided for in
the Indenture and in the TIA. Any Agent may do the same with like rights.

         19. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or shareholder of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture or
for any claim based on, in respect of or by reason of such obligations or their
creation. Each Holder of the Notes by accepting a Note waives and releases all
such liability. The waiver and release are part of the consideration for the
issue of the Notes.

         20. GOVERNING LAW. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL
GOVERN THE INDENTURE AND THE NOTES WITHOUT REGARD TO CONFLICT OF LAW PROVISIONS
THEREOF.

         21. AUTHENTICATION. The Notes shall not be valid until authenticated by
the manual signature of an authorized officer of the Trustee or an
authenticating agent.

         22. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and UGMA (= Uniform Gifts to
Minors Act).

                  The Company will furnish to any Holder of the Notes upon
written request and without charge a copy of the Indenture. Request may be made

                 5-1/2% CONVERTIBLE SUBORDINATED NOTE DUE 2007

                         ACCREDITED INVESTOR GLOBAL NOTE

         1. INTEREST. AKAMAI TECHNOLOGIES, INC., a Delaware corporation (the
"COMPANY"), is the issuer of 5-1/2% Convertible Subordinated Notes due 2007
(the "Notes"). The Notes will accrue interest at a rate of 5-1/2% per annum.
The Company promises to pay interest on the Notes in cash semiannually on each
July 1 and January 1, commencing on January 1, 2001, to Holders of record on the
immediately preceding June 15 and December 15, respectively. Interest on the
Notes will accrue from the most recent date to which interest has been paid, or
if no interest has been paid, from June 20, 2000. Interest will be computed on
the basis of a 360-day year of twelve 30-day months. The Company will pay
interest on overdue principal at the interest rate borne by the Notes,
compounded semiannually, and, to the extent permitted by law, it shall pay
interest on overdue installments of interest (without regard to any applicable
grace period) at the same interest rate compounded semiannually.

         2. REGISTRATION RIGHTS. The holder of this Note (and the Common Stock
issuable upon conversion hereof) is entitled to the benefits of a Registration
Rights Agreement, dated as of June 20, 2000, among the Company and the Initial
Purchasers (the "REGISTRATION RIGHTS AGREEMENT"). Pursuant to the Registration
Rights Agreement the Company has agreed for the benefit of the holders of
Transfer Restricted Securities, that (i) it will, at its cost, within 90 days
after the closing of the sale of the Notes (the "CLOSING"), file a shelf
registration statement (the "SHELF REGISTRATION STATEMENT") with the Securities
and Exchange Commission (the "COMMISSION") with respect to resales of the Notes
and the Common Stock issuable upon conversion thereof, (ii) it will use its
reasonable best efforts to cause such Shelf Registration Statement to be
declared effective within 180 days after the Closing, and (iii) it will use its
reasonable best efforts to keep such Shelf Registration Statement continuously
effective under the Securities Act, subject to certain exceptions specified in
the Registration Rights Agreement, until the second anniversary of the date of
the Closing. If (a) the Company fails to file the Shelf Registration Statement
required by the Registration Rights Agreement on or before the date specified
above for such filing, (b) such Shelf Registration Statement is not declared
effective by the Commission on or prior to the date specified above for such
effectiveness, or (c) the Shelf Registration Statement is declared effective but
thereafter ceases to be effective or useable in connection with resales of
Transfer Restricted Securities during the periods specified in the Registration
Rights Agreement without being succeeded immediately by a post-effective
amendment to such Shelf Registration Statement that cures such failure and is
itself declared effective immediately (each such event referred to in clauses
(a) through (c) above a "REGISTRATION DEFAULT"), then the Company will pay
special interest to each Holder of Transfer Restricted Securities as described
below. Notwithstanding the foregoing, as set forth in the Registration Rights
Agreement, the Company will be permitted to suspend use of the prospectus that
is part of the Shelf Registration Statement during certain periods of time and
in certain circumstances relating to pending corporate developments and public
filings with the SEC and similar events, and such a suspension shall not be
deemed a Registration Default provided it does not last in excess of 60 days in
the aggregate during any 12-month period. With respect to the first 90-day
period immediately following the occurrence of a Registration Default, the
Company shall pay special interest to each Holder of Transfer Restricted
Securities in an amount equal to an increase in the annual interest rate on the
Notes of 0.25%

                                      A-35
<PAGE>   98
("SPECIAL INTEREST") and with respect to each subsequent 90-day period,
additional amounts equal to an increase in the annual interest rate on the Notes
of 0.25% until all Registration Defaults have been cured, up to a maximum
increase in the annual interest rate on the Notes equal to 1.0%. In the event
that this Note, or any portion thereof, shall have been converted into shares of
Common Stock pursuant to Section 12 hereof, the amount payable under this
Section 2 per share of Common Stock so converted shall be determined by dividing
(x) the amount that would have been payable hereunder on the aggregate principal
amount so converted by (y) the number of shares of Common Stock issued upon such
conversion. All accrued Special Interest shall be paid by the Company on each
Interest Payment Date for which Special Interest is owed to the holders of
Transfer Restricted Securities by wire transfer of immediately available funds
or by federal funds check. Following the cure of all Registration Defaults, the
application of Special Interest will cease. THE PROVISIONS OF THIS SECTION 2
SHALL SURVIVE ANY CONVERSION OF THE NOTES INTO SHARES OF COMMON STOCK PURSUANT
TO SECTION 12 HEREOF, AND MAY BE ENFORCED BY THE HOLDER OF COMMON STOCK ISSUED
UPON CONVERSION OF THIS NOTE.

3. PAYMENTS. All payments made by the Company on this Note shall be made without
deduction or withholding for or on account of, any and all present or future
taxes, duties, assessments, or governmental charges of whatever nature unless
the deduction or withholding of such taxes, duties, assessments or government
charges is then required by law.

4. METHOD OF PAYMENT. The Company will pay interest on the Notes (except
defaulted interest) to the Persons who are registered Holders of Notes at the
close of business on the record date for the next interest payment date even
though Notes are canceled after the record date and on or before the interest
payment date. Holders must surrender Notes to a Paying Agent to collect
principal and premium payments. The Company will pay principal, premium, if any,
interest, and Special Interest, if any, in money of the United States that at
the time of payment is legal tender for payment of public and private debts.
However, the Company may pay principal, premium, if any, interest and Special
Interest, if any, by check payable in such money. It may mail an interest or
Special Interest check to a Holder's registered address. Upon the request of a
Holder who holds an aggregate principal amount of at least $5.0 million,
principal, premium, if any, interest, and Special Interest, if any, shall be
paid by wire transfer of immediately available funds to an account previously
specified in writing by such Holder to the Company and the Trustee.

5. PAYING AGENT, CONVERSION AGENT AND REGISTRAR. The Trustee will act as Paying
Agent, Conversion Agent and Registrar and will maintain an office or agency in
the City of New York, New York at which the notes may be presented for payment,
transfer or exchange. The Company may change any Paying Agent, Conversion Agent
or Registrar without prior notice. The Company or any of its Affiliates may act
in any such capacity.

6. INDENTURE. The Company issued the Notes under an Indenture, dated as of June
20, 2000 (the "INDENTURE"), between the Company and State Street Bank and Trust
Company, as Trustee. Capitalized terms herein are used as defined in the
Indenture unless otherwise defined herein. The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by the Trust
Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the "TIA") as in
effect on the date of the Indenture. The Notes are subject to, and qualified by,
all such terms, certain of which are summarized hereon, and Holders are referred
to the Indenture and such Act for a statement of such terms. The Notes are
unsecured general obligations of the Company limited to

                                      A-36
<PAGE>   99
$300,000,000 in aggregate principal amount and subordinated in right of payment
to all existing and future Senior Debt of the Company.

7. REDEMPTION. At any time on or after July 3, 2003 the Company may redeem any
portion of the Notes, in whole or in part, upon not less than 30 nor more than
60 days' notice, at the redemption prices (expressed as percentages of principal
amount thereof), together with accrued and unpaid interest and Special Interest
thereon to, but excluding, the applicable redemption date. If redeemed during
the period beginning July 3, 2003 and ending on June 30, 2004, the redemption
price shall be 103.143%, and if redeemed during the 12-month period commencing
on July 1 of each of the following years, up to the maturity date the redemption
price shall be the corresponding percentage of principal set forth below:

<TABLE>

         Period                                                                 Redemption Price
         ------                                                                 ----------------
<S>                                                                             <C>
         July 1, 2004 - June 30, 2005 ............................................  102.357%
         July 1, 2005 - June 30, 2006 ............................................  101.571%
         July 1, 2006 - June 30, 2007 ............................................  100.786%
         July 1, 2007 ............................................................  100.000%
</TABLE>

         In the event the Company redeems less than all of the outstanding
Notes, the Notes to be redeemed shall be selected by the Trustee in accordance
with Section 3.02 of the Indenture. In the event a portion of an outstanding
Note is selected for redemption and such Note is converted in part after such
selection, the converted portion of such Note shall be deemed (so far as may be)
to be the portion to be selected for redemption in accordance with Section 3.02
of the Indenture. The Company may not give notice of any redemption if the
Company has defaulted in payment of interest and the default is continuing.

         8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least
30 days but not more than 60 days before the redemption date to each Holder of
the Notes to be redeemed at his address of record. The Notes in denominations
larger than $1,000 may be redeemed in part but only in integral multiples of
$1,000. In the event of a redemption of less than all of the Notes, the Notes
will be chosen for redemption by the Trustee in accordance with the Indenture.
On and after the redemption date, interest ceases to accrue on the Notes or
portions of them called for redemption.

         If this Note is redeemed subsequent to a record date with respect to
any interest payment date specified above and on or prior to such interest
payment date, then any accrued interest will be paid to the Person in whose name
this Note is registered at the close of business on such record date.

         9. MANDATORY REDEMPTION. The Company will not be required to make
mandatory redemption or repurchase payments with respect to the Notes. There are
no sinking fund payments with respect to the Notes.

         10. REPURCHASE AT OPTION OF HOLDER. If there is a Fundamental Change,
the Company shall be required to offer to purchase on the Purchase Date all
outstanding Notes at a purchase price equal to 100% of the aggregate principal
amount thereof, plus accrued and unpaid interest and Special Interest, if any,
to the Purchase Date. Holders of Notes that are subject to an offer to purchase
will receive a Fundamental Change Offer from the Company in accordance with

                                      A-37
<PAGE>   100
Section 3.09 of the Indenture and may elect to have such Notes or portions
thereof in authorized denominations purchased by completing the form entitled
"Option of Holder to Elect Purchase" appearing below.

         11. SUBORDINATION. The payment of the principal of, interest on,
Special Interest or any other amounts due on the Notes is subordinated in right
of payment to all existing and future Senior Debt of the Company, as described
in the Indenture. Each Holder, by accepting a Note, agrees to such subordination
and authorizes and directs the Trustee on its behalf to take such action as may
be necessary or appropriate to effectuate the subordination so provided and
appoints the Trustee as its attorney-in-fact for such purpose.

         12. CONVERSION. The holder of any Note has the right, exercisable at
any time following the Issuance Date and prior to the close of business (New
York time) on the date of the Note's maturity, to convert the principal amount
thereof (or any portion thereof that is an integral multiple of $1,000) into
shares of Common Stock at the initial Conversion Price of $115.47 per share,
subject to adjustment under certain circumstances as set forth in the Indenture,
except that if a Note is called for redemption, the conversion right will
terminate at the close of business on the Business Day immediately preceding the
date fixed for redemption.

         To convert a Note, a holder must (1) complete and sign a conversion
notice substantially in the form set forth below, (2) surrender the Note to a
Conversion Agent, (3) furnish appropriate endorsements or transfer documents if
required by the Registrar or Conversion Agent and (4) pay any transfer or
similar tax, if required. No payment or adjustment will be made for accrued and
unpaid interest on a converted Note, but if any holder surrenders a Note for
conversion after the close of business on the record date for the payment of an
installment of interest and prior to the opening of business on the next
interest payment date, then, notwithstanding such conversion, the interest
payable on such interest payment date shall be paid to the holder of such Note
on such record date. Any Notes that are, however, delivered to the Company for
conversion after any record date but before the next interest payment date must,
except as described in the next sentence, be accompanied by a payment equal to
the interest payable on such interest payment date on the principal amount of
such Notes being converted. Payments to the Company described in the preceding
sentence shall not be required if, during that period between a record date and
the next interest payment date, a conversion occurs on or after the date that
the Company has issued a redemption notice and prior to the date of redemption
stated in such notice. If any Notes are converted after an interest payment date
but on or before the next record date, no interest will be paid on those Notes.
The number of shares issuable upon conversion of a Note is determined by
dividing the principal amount of the Note converted by the Conversion Price in
effect on the Conversion Date. No fractional shares will be issued upon
conversion but a cash adjustment will be made for any fractional interest.

         A note in respect of which a holder has delivered an "Option of Holder
to Elect Purchase" form appearing below exercising the option of such holder to
require the Company to purchase such Note may be converted only if the notice of
exercise is withdrawn as provided above and in accordance with the terms of the
Indenture. The above description of conversion of the Notes is qualified by
reference to, and is subject in its entirety by, the more complete description
thereof contained in the Indenture.

                                      A-38
<PAGE>   101
         13. DENOMINATIONS, TRANSFER, EXCHANGE. The notes are in registered
form, without coupons, in denominations of $1,000 and integral multiples of
$1,000. The transfer of Notes may be registered, and Notes may be exchanged, as
provided in the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
any taxes and fees required by law or permitted by the Indenture. The Registrar
need not exchange or register the transfer of any Note or portion of a Note
selected for redemption (except the unredeemed portion of any Note being
redeemed in part). Also, it need not exchange or register the transfer of any
Note for a period of 15 days before a selection of Notes to be redeemed.

         14. PERSONS DEEMED OWNERS. The registered Holder of a Note may be
treated as its owner for all purposes.

         15. UNCLAIMED MONEY. If money for the payment of principal or interest
remains unclaimed for two years, the Trustee and the Paying Agent shall pay the
money back to the Company at its written request. After that, Holders of Notes
entitled to the money must look to the Company for payment unless an abandoned
property law designates another Person and all liability of the Trustee and such
Paying Agent with respect to such money shall cease.

         16. DEFAULTS AND REMEDIES. The Notes shall have the Events of Default
set forth in Section 8.01 of the Indenture. Subject to certain limitations in
the Indenture, if an Event of Default occurs and is continuing, the Trustee by
notice to the Company or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes by notice to the Company and the Trustee
may declare all the Notes to be due and payable immediately, except that in the
case of an Event of Default arising from certain events of bankruptcy,
insolvency or reorganization, all unpaid principal and interest accrued on the
Notes shall become due and payable immediately without further action or notice.
The Holders of a majority in principal amount of the Notes then outstanding by
written notice to the Trustee may rescind an acceleration and its consequences
if the rescission would not conflict with any judgment or decree and if all
existing Events of Default have been cured or waived except nonpayment of
principal or interest that has become due solely because of the acceleration.
Holders may not enforce the Indenture or the Notes except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in principal
amount of the then outstanding Notes issued under the Indenture may direct the
Trustee in its exercise of any trust or power. The Company must furnish annually
compliance certificates to the Trustee. The above description of Events of
Default and remedies is qualified by reference, and subject in its entirety, to
the more complete description thereof contained in the Indenture.

         17. AMENDMENTS, SUPPLEMENTS AND WAIVERS. Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Notes (including consents obtained in connection with a tender offer or exchange
offer for Notes), and any existing default may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes. Without
the consent of any Holder, the Indenture or the Notes may be amended, among
other reasons, to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for assumption of the Company's obligations to Holders, to make any
change that does not adversely affect the rights of any Holder or to qualify the
Indenture under the TIA or to comply with the requirements of the SEC in order
to maintain the qualification of the Indenture under the TIA.

                                      A-39
<PAGE>   102
         18. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee, in its individual
or any other capacity may become the owner or pledgee of the Notes and may
otherwise deal with the Company or an Affiliate with the same rights it would
have, as if it were not Trustee, subject to certain limitations provided for in
the Indenture and in the TIA. Any Agent may do the same with like rights.

         19. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or shareholder of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture or
for any claim based on, in respect of or by reason of such obligations or their
creation. Each Holder of the Notes by accepting a Note waives and releases all
such liability. The waiver and release are part of the consideration for the
issue of the Notes.

         20. GOVERNING LAW. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL
GOVERN THE INDENTURE AND THE NOTES WITHOUT REGARD TO CONFLICT OF LAW PROVISIONS
THEREOF.

         21. AUTHENTICATION. The Notes shall not be valid until authenticated by
the manual signature of an authorized officer of the Trustee or an
authenticating agent.

         22. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and UGMA (= Uniform Gifts to
Minors Act).

                  The Company will furnish to any Holder of the Notes upon
written request and without charge a copy of the Indenture. Request may be made

                 5 1/2% CONVERTIBLE SUBORDINATED NOTE DUE 2007

         1. INTEREST. AKAMAI TECHNOLOGIES, INC., a Delaware corporation (the
"COMPANY"), is the issuer of 5 1/2% Convertible Subordinated Notes due 2007 (the
"Notes"). The Notes will accrue interest at a rate of 5 1/2% per annum. The
Company promises to pay interest on the Notes in cash semiannually on each July
1 and January 1, commencing on January 1, 2001, to Holders of record on the
immediately preceding June 15 and December 15, respectively. Interest on the
Notes will accrue from the most recent date to which interest has been paid, or
if no interest has been paid, from June 20, 2000. Interest will be computed on
the basis of a 360-day year of twelve 30-day months. The Company will pay
interest on overdue principal at the interest rate borne by the Notes,
compounded semiannually, and, to the extent permitted by law, it shall pay
interest on overdue installments of interest (without regard to any applicable
grace period) at the same interest rate compounded semiannually.

         2. REGISTRATION RIGHTS. The holder of this Note (and the Common Stock
issuable upon conversion hereof) is entitled to the benefits of a Registration
Rights Agreement, dated as of June 20, 2000, among the Company and the Initial
Purchasers (the "REGISTRATION RIGHTS AGREEMENT"). Pursuant to the Registration
Rights Agreement the Company has agreed for the benefit of the holders of
Transfer Restricted Securities, that (i) it will, at its cost, within 90 days
after the closing of the sale of the Notes (the "CLOSING"), file a shelf
registration statement (the "SHELF REGISTRATION STATEMENT") with the Securities
and Exchange Commission (the "COMMISSION") with respect to resales of the Notes
and the Common Stock issuable upon conversion thereof, (ii) it will use its
reasonable best efforts to cause such Shelf Registration Statement to be
declared effective within 180 days after the Closing, and (iii) it will use its
reasonable best efforts to keep such Shelf Registration Statement continuously
effective under the Securities Act, subject to certain exceptions specified in
the Registration Rights Agreement, until the second anniversary of the date of
the Closing. If (a) the Company fails to file the Shelf Registration Statement
required by the Registration Rights Agreement on or before the date specified
above for such filing, (b) such Shelf Registration Statement is not declared
effective by the Commission on or prior to the date specified above for such
effectiveness, or (c) the Shelf Registration Statement is declared effective but
thereafter ceases to be effective or useable in connection with resales of
Transfer Restricted Securities during the periods specified in the Registration
Rights Agreement without being succeeded immediately by a post-effective
amendment to such Shelf Registration Statement that cures such failure and is
itself declared effective immediately (each such event referred to in clauses
(a) through (c) above a "REGISTRATION DEFAULT"), then the Company will pay
special interest to each Holder of Transfer Restricted Securities as described
below. Notwithstanding the foregoing, as set forth in the Registration Rights
Agreement, the Company will be permitted to suspend use of the prospectus that
is part of the Shelf Registration Statement during certain periods of time and
in certain circumstances relating to pending corporate developments and public
filings with the SEC and similar events, and such a suspension shall not be
deemed a Registration Default provided it does not last in excess of 60 days in
the aggregate during any 12-month period. With respect to the first 90-day
period immediately following the occurrence of a Registration Default, the
Company shall pay special interest to each Holder of Transfer Restricted
Securities in an amount equal to an increase in the annual interest rate on the
Notes of 0.25% ("SPECIAL INTEREST") and with respect to each subsequent 90-day
period, additional amounts

                                      A-50
<PAGE>   113
equal to an increase in the annual interest rate on the Notes of 0.25% until all
Registration Defaults have been cured, up to a maximum increase in the annual
interest rate on the Notes equal to 1.0%. In the event that this Note, or any
portion thereof, shall have been converted into shares of Common Stock pursuant
to Section 12 hereof, the amount payable under this Section 2 per share of
Common Stock so converted shall be determined by dividing (x) the amount that
would have been payable hereunder on the aggregate principal amount so converted
by (y) the number of shares of Common Stock issued upon such conversion. All
accrued Special Interest shall be paid by the Company on each Interest Payment
Date for which Special Interest is owed to the holders of Transfer Restricted
Securities by wire transfer of immediately available funds or by federal funds
check. Following the cure of all Registration Defaults, the application of
Special Interest will cease. THE PROVISIONS OF THIS SECTION 2 SHALL SURVIVE ANY
CONVERSION OF THE NOTES INTO SHARES OF COMMON STOCK PURSUANT TO SECTION 12
HEREOF, AND MAY BE ENFORCED BY THE HOLDER OF COMMON STOCK ISSUED UPON CONVERSION
OF THIS NOTE.

         3. PAYMENTS. All payments made by the Company on this Note shall be
made without deduction or withholding for or on account of, any and all present
or future taxes, duties, assessments, or governmental charges of whatever nature
unless the deduction or withholding of such taxes, duties, assessments or
government charges is then required by law.

         4. METHOD OF PAYMENT. The Company will pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders of Notes
at the close of business on the record date for the next interest payment date
even though Notes are canceled after the record date and on or before the
interest payment date. Holders must surrender Notes to a Paying Agent to collect
principal and premium payments. The Company will pay principal, premium, if any,
interest, and Special Interest, if any, in money of the United States that at
the time of payment is legal tender for payment of public and private debts.
However, the Company may pay principal, premium, if any, interest and Special
Interest, if any, by check payable in such money. It may mail an interest or
Special Interest check to a Holder's registered address. Upon the request of a
Holder who holds an aggregate principal amount of at least $5.0 million,
principal, premium, if any, interest, and Special Interest, if any, shall be
paid by wire transfer of immediately available funds to an account previously
specified in writing by such Holder to the Company and the Trustee.

         5. PAYING AGENT, CONVERSION AGENT AND REGISTRAR. The Trustee will act
as Paying Agent, Conversion Agent and Registrar and will maintain an office or
agency in the City of New York, New York at which the notes may be presented for
payment, transfer or exchange. The Company may change any Paying Agent,
Conversion Agent or Registrar without prior notice. The Company or any of its
Affiliates may act in any such capacity.

         6. INDENTURE. The Company issued the Notes under an Indenture, dated as
of June 20, 2000 (the "INDENTURE"), between the Company and State Street Bank
and Trust Company, as Trustee. Capitalized terms herein are used as defined in
the Indenture unless otherwise defined herein. The terms of the Notes include
those stated in the Indenture and those made part of the Indenture by the Trust
Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the "TIA") as in
effect on the date of the Indenture. The Notes are subject to, and qualified by,
all such terms, certain of which are summarized hereon, and Holders are referred
to the Indenture and such Act for a statement of such terms. The Notes are
unsecured general obligations of the Company limited to

                                      A-51
<PAGE>   114
$300,000,000 in aggregate principal amount and subordinated in right of payment
to all existing and future Senior Debt of the Company.

         7. REDEMPTION. At any time on or after July 3, 2003 the Company may
redeem any portion of the Notes, in whole or in part, upon not less than 30 nor
more than 60 days' notice, at the redemption prices (expressed as percentages of
principal amount thereof), together with accrued and unpaid interest and Special
Interest thereon to, but excluding, the applicable redemption date. If redeemed
during the period beginning July 3, 2003 and ending on June 30, 2004, the
redemption price shall be 103.143%, and if redeemed during the 12-month period
commencing on July 1 of each of the following years, up to the maturity date the
redemption price shall be the corresponding percentage of principal set forth
below:

<TABLE>

         Period                                                                 Redemption Price
         ------                                                                 ----------------
<S>                                                                             <C>
         July 1, 2004 - June 30, 2005 ...........................................  102.357%
         July 1, 2005 - June 30, 2006 ...........................................  101.571%
         July 1, 2006 - June 30, 2007 ...........................................  100.786%
         July 1, 2007 ...........................................................  100.000%
</TABLE>

         In the event the Company redeems less than all of the outstanding
Notes, the Notes to be redeemed shall be selected by the Trustee in accordance
with Section 3.02 of the Indenture. In the event a portion of an outstanding
Note is selected for redemption and such Note is converted in part after such
selection, the converted portion of such Note shall be deemed (so far as may be)
to be the portion to be selected for redemption in accordance with Section 3.02
of the Indenture. The Company may not give notice of any redemption if the
Company has defaulted in payment of interest and the default is continuing.

         8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least
30 days but not more than 60 days before the redemption date to each Holder of
the Notes to be redeemed at his address of record. The Notes in denominations
larger than $1,000 may be redeemed in part but only in integral multiples of
$1,000. In the event of a redemption of less than all of the Notes, the Notes
will be chosen for redemption by the Trustee in accordance with the Indenture.
On and after the redemption date, interest ceases to accrue on the Notes or
portions of them called for redemption.

         If this Note is redeemed subsequent to a record date with respect to
any interest payment date specified above and on or prior to such interest
payment date, then any accrued interest will be paid to the Person in whose name
this Note is registered at the close of business on such record date.

         9. MANDATORY REDEMPTION. The Company will not be required to make
mandatory redemption or repurchase payments with respect to the Notes. There are
no sinking fund payments with respect to the Notes.

         10. REPURCHASE AT OPTION OF HOLDER. If there is a Fundamental Change,
the Company shall be required to offer to purchase on the Purchase Date all
outstanding Notes at a purchase price equal to 100% of the aggregate principal
amount thereof, plus accrued and unpaid interest and Special Interest, if any,
to the Purchase Date. Holders of Notes that are subject to an offer to purchase
will receive a Fundamental Change Offer from the Company in accordance with

                                      A-52
<PAGE>   115
Section 3.09 of the Indenture and may elect to have such Notes or portions
thereof in authorized denominations purchased by completing the form entitled
"Option of Holder to Elect Purchase" appearing below.

         11. SUBORDINATION. The payment of the principal of, interest on,
Special Interest or any other amounts due on the Notes is subordinated in right
of payment to all existing and future Senior Debt of the Company, as described
in the Indenture. Each Holder, by accepting a Note, agrees to such subordination
and authorizes and directs the Trustee on its behalf to take such action as may
be necessary or appropriate to effectuate the subordination so provided and
appoints the Trustee as its attorney-in-fact for such purpose.

         12. CONVERSION. The holder of any Note has the right, exercisable at
any time following the Issuance Date and prior to the close of business (New
York time) on the date of the Note's maturity, to convert the principal amount
thereof (or any portion thereof that is an integral multiple of $1,000) into
shares of Common Stock at the initial Conversion Price of $115.47 per share,
subject to adjustment under certain circumstances as set forth in the Indenture,
except that if a Note is called for redemption, the conversion right will
terminate at the close of business on the Business Day immediately preceding the
date fixed for redemption.

         To convert a Note, a holder must (1) complete and sign a conversion
notice substantially in the form set forth below, (2) surrender the Note to a
Conversion Agent, (3) furnish appropriate endorsements or transfer documents if
required by the Registrar or Conversion Agent and (4) pay any transfer or
similar tax, if required. No payment or adjustment will be made for accrued and
unpaid interest on a converted Note, but if any holder surrenders a Note for
conversion after the close of business on the record date for the payment of an
installment of interest and prior to the opening of business on the next
interest payment date, then, notwithstanding such conversion, the interest
payable on such interest payment date shall be paid to the holder of such Note
on such record date. Any Notes that are, however, delivered to the Company for
conversion after any record date but before the next interest payment date must,
except as described in the next sentence, be accompanied by a payment equal to
the interest payable on such interest payment date on the principal amount of
such Notes being converted. Payments to the Company described in the preceding
sentence shall not be required if, during that period between a record date and
the next interest payment date, a conversion occurs on or after the date that
the Company has issued a redemption notice and prior to the date of redemption
stated in such notice. If any Notes are converted after an interest payment date
but on or before the next record date, no interest will be paid on those Notes.
The number of shares issuable upon conversion of a Note is determined by
dividing the principal amount of the Note converted by the Conversion Price in
effect on the Conversion Date. No fractional shares will be issued upon
conversion but a cash adjustment will be made for any fractional interest.

         A note in respect of which a holder has delivered an "Option of Holder
to Elect Purchase" form appearing below exercising the option of such holder to
require the Company to purchase such Note may be converted only if the notice of
exercise is withdrawn as provided above and in accordance with the terms of the
Indenture. The above description of conversion of the Notes is qualified by
reference to, and is subject in its entirety by, the more complete description
thereof contained in the Indenture.

                                      A-53
<PAGE>   116
         13. DENOMINATIONS, TRANSFER, EXCHANGE. The notes are in registered
form, without coupons, in denominations of $1,000 and integral multiples of
$1,000. The transfer of Notes may be registered, and Notes may be exchanged, as
provided in the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
any taxes and fees required by law or permitted by the Indenture. The Registrar
need not exchange or register the transfer of any Note or portion of a Note
selected for redemption (except the unredeemed portion of any Note being
redeemed in part). Also, it need not exchange or register the transfer of any
Note for a period of 15 days before a selection of Notes to be redeemed.

         14. PERSONS DEEMED OWNERS. The registered Holder of a Note may be
treated as its owner for all purposes.

         15. UNCLAIMED MONEY. If money for the payment of principal or interest
remains unclaimed for two years, the Trustee and the Paying Agent shall pay the
money back to the Company at its written request. After that, Holders of Notes
entitled to the money must look to the Company for payment unless an abandoned
property law designates another Person and all liability of the Trustee and such
Paying Agent with respect to such money shall cease.

         16. DEFAULTS AND REMEDIES. The Notes shall have the Events of Default
set forth in Section 8.01 of the Indenture. Subject to certain limitations in
the Indenture, if an Event of Default occurs and is continuing, the Trustee by
notice to the Company or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes by notice to the Company and the Trustee
may declare all the Notes to be due and payable immediately, except that in the
case of an Event of Default arising from certain events of bankruptcy,
insolvency or reorganization, all unpaid principal and interest accrued on the
Notes shall become due and payable immediately without further action or notice.
The Holders of a majority in principal amount of the Notes then outstanding by
written notice to the Trustee may rescind an acceleration and its consequences
if the rescission would not conflict with any judgment or decree and if all
existing Events of Default have been cured or waived except nonpayment of
principal or interest that has become due solely because of the acceleration.
Holders may not enforce the Indenture or the Notes except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in principal
amount of the then outstanding Notes issued under the Indenture may direct the
Trustee in its exercise of any trust or power. The Company must furnish annually
compliance certificates to the Trustee. The above description of Events of
Default and remedies is qualified by reference, and subject in its entirety, to
the more complete description thereof contained in the Indenture.

         17. AMENDMENTS, SUPPLEMENTS AND WAIVERS. Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Notes (including consents obtained in connection with a tender offer or exchange
offer for Notes), and any existing default may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes. Without
the consent of any Holder, the Indenture or the Notes may be amended, among
other reasons, to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for assumption of the Company's obligations to Holders, to make any
change that does not adversely affect the rights of any Holder or to qualify the
Indenture under the TIA or to comply with the requirements of the SEC in order
to maintain the qualification of the Indenture under the TIA.

                                      A-54
<PAGE>   117
         18. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee, in its individual
or any other capacity may become the owner or pledgee of the Notes and may
otherwise deal with the Company or an Affiliate with the same rights it would
have, as if it were not Trustee, subject to certain limitations provided for in
the Indenture and in the TIA. Any Agent may do the same with like rights.

         19. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or shareholder of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture or
for any claim based on, in respect of or by reason of such obligations or their
creation. Each Holder of the Notes by accepting a Note waives and releases all
such liability. The waiver and release are part of the consideration for the
issue of the Notes.

         20. GOVERNING LAW. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL
GOVERN THE INDENTURE AND THE NOTES WITHOUT REGARD TO CONFLICT OF LAW PROVISIONS
THEREOF.

         21. AUTHENTICATION. The Notes shall not be valid until authenticated by
the manual signature of an authorized officer of the Trustee or an
authenticating agent.

         22. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and UGMA (= Uniform Gifts to
Minors Act).

                  The Company will furnish to any Holder of the Notes upon
written request and without charge a copy of the Indenture. Request may be made

Akamai Technologies, Inc.

Ladies and Gentlemen:

         We are delivering this letter in connection with our acquisition of
5 1/2% Convertible Subordinated Notes due 2007 (the "Notes") of Akamai
Technologies, Inc., a Delaware corporation (the "Company"), as more fully
described in the Offering Memorandum (the "Offering Memorandum") relating to the
initial offering of the Notes.

         We hereby confirm that:

         (i) we are an "accredited investor" within the meaning of Rule 501(a)
(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act"), or an entity in which all of the equity owners are accredited
investors within the meaning of Rule 501(a) (1), (2), (3) or (7) under the
Securities Act (an "Institutional Accredited Investor");

         (ii) (A) any purchase of the Notes by us will be for our own account or
for the account of one or more other Institutional Accredited Investors or as
fiduciary for the account of one or more trusts, each of which is an "accredited
investor" within the meaning of Rule 501(a)(7) under the Securities Act and for
each of which we exercise sole investment discretion or (B) we are a "bank,"
within the meaning of Section 3 (a) (2) of the Securities Act, or a "savings and
loan association" or other institution described in Section 3(a)(5)(A) of the
Securities Act that is acquiring the Notes as fiduciary for the account of one
or more institutions for which we exercise sole investment discretion;

         (iii) in the event that we purchase any of the Notes, we will acquire
Notes having a minimum purchase price of not less than $100,000 for our own
account or for any separate account for which we are acting;

         (iv) we have such knowledge and experience in financial and business
matters that we are capable of evaluating the merits and risks of purchasing the
Notes;

         (v) we are not acquiring the Notes with a view to distribution thereof
or with any present intention of offering or selling any of the Notes, except
inside the United States in accordance

                                      E-1
<PAGE>   129
with Rule 144A under the Securities Act or outside the United States in
accordance with Regulation S under the Securities Act, as provided below,
provided that the disposition of our property and the property of any accounts
for which we are acting as fiduciary shall remain at all times within our
control; and

         (vi) we have received a copy of the Offering Memorandum relating to the
offering of the Notes and acknowledge that we have had access to such financial
and other information, and have been afforded the opportunity to ask such
questions of representatives of the Company and receive answers thereto, as we
deem necessary in connection with our decision to acquire the Notes.

         We understand that the Notes are being offered in a transaction not
involving any public offering within the United States within the meaning of the
Securities Act and that the Notes have not been registered under the Securities
Act, and we agree, on our own behalf and on behalf of each account for which we
acquire any Notes, that if in the future we decide to resell, pledge or
otherwise transfer such Notes, such Notes may be offered, resold, pledged or
otherwise transferred only: (a) to the Company or any of its subsidiaries, (b)
to a person whom the seller reasonably believes is a Qualified Institutional
Buyer or "QIB" (as defined in Rule 144A under the Securities Act) purchasing for
its own account or for the account of a QIB in a transaction meeting the
requirements of Rule 144A, (c) in an offshore transaction meeting the
requirements of Rule 904 of the Securities Act, (d) in a transaction meeting the
requirements of Rule 144 under the Securities Act, (e) to an Institutional
Accredited Investor that, prior to such transfer, furnishes the trustee a signed
letter containing certain representations and agreements relating to the
transfer of the Notes (in substantially this form) and, if such transfer is in
respect of an aggregate principal amount of Notes less than $100,000, an opinion
of counsel acceptable to the Company that such transfer is in compliance with
the Securities Act, (f) in accordance with another exemption from the
registration requirements of the Securities Act (and based upon an opinion of
counsel acceptable to the Company) or (g) pursuant to an effective registration
statement and, in each case, in accordance with the applicable securities laws
of any state of the United States, or any other applicable jurisdiction. We
understand that the registrar and transfer agent for the Notes will not be
required to accept for registration of transfer any Notes acquired by us, except
upon presentation of evidence satisfactory to the Company and the transfer agent
that the foregoing restrictions on transfer have been complied with. We further
understand that any Notes acquired by us will be in the form of definitive
physical certificates and will bear a legend reflecting the substance of this
paragraph.

         We acknowledge that the Company and others will rely upon our
confirmations, acknowledgments and agreements set forth herein, and we agree to
notify you promptly in writing if any of our representatives or warranties
herein ceases to be accurate and complete.
