In the event of any Liquidation, whether voluntary or involuntary, before any payment of cash or distribution of other property shall be made to the Series C Preferred Stockholders, Series E Preferred Stockholders or the Common Stockholders or any other class or series of stock ranking on Liquidation junior to the Series A Preferred Stock, the holders of Series A Preferred Stock shall be entitled to receive out of the assets of the Corporation legally available for distribution to its stockholders, pari passu with the rights of the Series B and Series D Preferred Stockholders, an amount per share equal to the Series A Preferred Original Purchase Price whether from capital, surplus or earnings, plus an amount equal to any accrued but unpaid cumulative dividends thereon and any declared but unpaid dividends thereon. 4. <PAGE> c.

For purposes of calculating the amount of any payment to be paid pursuant to this Section A.4(e) upon any such Liquidation, each share of Series A, Series B and Series D Preferred Stock shall be deemed to be that number of shares of Common Stock into which such share is then convertible, rounded to the nearest one-tenth of a share. 5. Merger, Consolidation, etc. a. In the event the Corporation intends to sell, lease or otherwise dispose of all or substantially all of the assets of the Corporation, effect any transaction or series of related transactions in which more than 50% of the voting power of the Corporation is transferred (other than in connection with a Public Offering), or merge or consolidate with or into any other corporation, corporations or other entity or entities (other than a merger or consolidation in which the Series Preferred Stockholders receive securities of the surviving corporation having substantially similar rights to the Series Preferred Stock and in which the stockholders of the Corporation immediately prior to such a transaction are holders of at least a majority of the voting securities of the surviving corporation immediately thereafter), then the Corporation shall give written notice to each Series Preferred Stockholder no less than 20 days prior to the closing of any such transaction notifying the Series Preferred Stockholders of the terms and timing of the closing of such transaction and of the rights of the Series Preferred Stockholders under Sections A.5(b), B.5(b), C.5(b), D.5(b) and E.5(b) hereof. b. Upon the affirmative vote of the holders of not less than 75% in voting power of all of the shares of Series Preferred Stock then outstanding, voting together as a separate class, made prior to the consummation of such transaction, the proceeds of or any property deliverable from such transaction shall be distributed among the holders of the Series Preferred Stock and the Common Stock according to the provisions of Sections A.4, B.4, C.4, D.4 and E.4 hereof as if such transaction were a Liquidation. c. The voting rights of the holders of Series Preferred Stock contained in Sections A.5(b), B.5(b), C.5(b), D.5(b) and E.5(b) hereof may be exercised at a special meeting of the holders of Series Preferred Stockholders called as provided in accordance with the By-laws of the Corporation or by written consent of the holders of Series Preferred Stock in lieu of a meeting. 6. Voting. a. General. In addition to the rights otherwise provided for herein or by law, the Series A Preferred Stockholders shall be entitled to vote, together with the Series B Preferred Stockholders, the Series C Preferred Stockholders, the Series D Preferred Stockholders, the Series E Preferred Stockholders and the Common Stockholders and any other class or series of stock then entitled to vote, as one class on all matters as to which Common Stockholders shall be entitled to vote, in the same manner and with the same effect as the Common Stockholders, except as otherwise required by the General Corporation Law. In any such vote, and in any vote or action of the Series A Preferred Stockholders voting together as a separate class or with the other holders of Series Preferred Stock as a separate class, each share of issued and outstanding Series A Preferred Stock shall entitle the holder thereof to one vote per 6. <PAGE> share for each share of Common Stock (including fractional shares) into which each share of Series A Preferred Stock is then convertible, rounded to the nearest one-tenth of a share. b. Election of Board of Directors. (i) In addition to the rights specified in Sections A.6(a), B.6(a), C.6(a) and D.6(a) hereof, the holders of a majority in voting power of the Series A, Series B, Series C and Series D Preferred Stock, voting together as a separate class or in such other manner as the holders of the Series A, Series B, Series C and Series D Preferred Stock shall agree among themselves in the Stockholders' Agreement, shall have the exclusive right to elect to the Board of Directors of the Corporation that number of directors which shall be equal to a majority of the total number of directors on the Board of Directors at any given time. In any election of Preferred Directors pursuant to this Section A.6(b) and Sections B.6(b), C.6(b) and D.6(b), each share of issued and outstanding Series A, Series B, Series C and Series D Preferred Stock shall entitle the holder thereof to the number of votes per share that equals the number of shares of Common Stock (including fractional shares) into which each such share is then convertible, rounded up to the nearest one-tenth of a share. The voting rights of the Series A, Series B, Series C and Series D Preferred Stockholders contained in this Section A.6(b) and Sections B.6(b), C.6(b) and D.6(b) may be exercised at a special meeting of the Series Preferred Stockholders called as provided in accordance with the By-laws of the Corporation, at any annual or special meeting of the Stockholders of the Corporation, or by written consent of the holders of Series Preferred Stock in lieu of a meeting. The Preferred Directors elected pursuant to this Section A.6(b) and Sections B.6(b), C.6(b) and D.6(b) shall serve from the date of their election and qualification until their successors have been duly elected and qualified. (ii) Notwithstanding anything to the contrary contained in Sections A.6(b)(i), B.6(b)(i), C.6(b)(i) and D.6(b)(i) hereof, if an Event of Noncompliance is declared in accordance with the Stockholders' Agreement, the Series A, Series B, Series C and Series D Preferred Stockholders, voting together as a separate class, shall have the right to elect all of the members of the Board of Directors of the Corporation.

Protective Provisions. So long as any Series Preferred Stock is outstanding, the Corporation shall not, without the written consent in lieu of a meeting, or the affirmative vote at a meeting called for such purpose, of the holders of shares representing at least 75% of the combined voting power of the issued and outstanding Series A, Series B, Series C, Series D and Series E Preferred Stock, voting together as a single class: (i) except for "Excluded Stock", authorize, issue or agree to authorize or issue any shares of capital stock of the Corporation, any right, warrant, or option to 7. <PAGE> receive any capital stock, or any security convertible into or exchangeable for capital stock or any capitalized lease with any equity feature with respect to the capital stock of the Corporation; (ii) change as a whole, by subdivision or combination in any manner, the number of shares of the Common Stock then outstanding into a different number of shares, with or without par value, without making the identical change as a whole in the number of shares of Series Preferred Stock then outstanding; (iii) amend, alter or repeal, in any manner whatsoever, the designations, powers, preferences, relative, participating, optional or other special rights, qualifications, limitations and restrictions of the Series Preferred Stock; (iv) sell, abandon, transfer, lease or otherwise dispose of all or substantially all of the properties or assets of the Corporation or any of its subsidiaries; (v) declare or pay any dividend (other than as required by Section A.3(d) hereof in respect of the Series A Preferred Stock, by Section B.3(d) hereof in respect of the Series B Preferred Stock and by Section D.3(d) hereof in respect of the Series D Preferred Stock) or make any distribution (whether in cash, shares of capital stock of the Corporation, or other property) on shares of its capital stock other than the Series Preferred Stock; (vi) merge or consolidate with or into, or permit any subsidiary of the Corporation to merge or consolidate with or into, any other corporation, corporations or other entity or entities, or effect any transaction or series of related transactions in which more than 50% of the voting power of the Corporation is transferred (other than in connection with a Public Offering); (vii) voluntarily dissolve, liquidate or wind-up or carry out any partial Liquidation or distribution or transaction in the nature of a partial Liquidation or distribution; (viii) increase the number of shares of any series of Preferred Stock of the Corporation authorized to be issued; (ix) reclassify any shares of the Corporation's capital stock as shares ranking senior to or on parity with the Series Preferred Stock with respect to rights on Liquidation, redemption or for the payment of any dividend or distribution other than in Liquidation; (x) amend, alter or repeal any provision of the Certificate of Incorporation of the Corporation; (xi) amend, alter or repeal any provisions of the By-laws of the Corporation so as to adversely affect the rights of the holders of the Series Preferred Stock; or (xii) directly or indirectly, redeem, purchase or otherwise acquire for value (including through an exchange), or set apart money or other property for any 8. <PAGE> mandatory purchase or other analogous fund for the redemption, purchase or acquisition of, any shares of Common Stock, except (a) pursuant to Sections A.8, B.8, C.8 and D.8 hereof, and (b) pursuant to any agreement approved by the Board of Directors with an officer, director, employee or consultant providing for the repurchase of any capital stock of the Corporation owned by such officer, director, employee or consultant at the option of the Corporation, which is either (A) set forth on Schedule 4.10 of the Series B Stock Purchase Agreement, or (B) issued pursuant to the Option Plan, as amended, the 1997 Equity Incentive Plan, or any other stock option plan of the Corporation or one or more amendments to the Option Plan, from and after May 13, 1996, approved by the Board of Directors and by the holders of 75% of the then issued and outstanding Series Preferred Stock, voting together as a separate class. In any vote or written consent in lieu of a meeting pursuant to this Section A.6(c) and Sections B.6(c), C.6(c), D.6(c) and E.6(c) hereof, each share of issued and outstanding Series Preferred Stock shall entitle the holder thereof to the number of votes per share that equals the number of shares of Common Stock (including fractional shares) into which each such share is then convertible, rounded to the nearest one-tenth of a share. 7. Conversion. a. Right to Convert. (i) Any Series A Preferred Stockholder shall have the right, at any time or from time to time, prior to the Closing Date to convert any or all of its shares of Series A Preferred Stock into that number of fully paid and nonassessable shares of Common Stock for each share of Series A Preferred Stock so converted equal to the quotient of the Series A Preferred Original Purchase Price divided by the Series A Preferred Conversion Price (as last adjusted and then in effect) rounded to the nearest one-tenth of a share. (ii) (a) Any Series A Preferred Stock that remains unconverted on the Closing Date shall be automatically converted without notice and without any action on the part of the holder thereof into shares of Common Stock on the Closing Date in accordance with the preceding sentence. After the Closing Date all rights of holders of shares of Series A Preferred Stock with respect to Series A Preferred Stock, except the right to receive shares of Common Stock in accordance with this Section A.7(a)(ii)(a) and any accrued but unpaid dividends and any declared but unpaid dividends as in accordance with Section A.7(a)(ii)(c) hereof, shall cease and the shares of Series A Preferred Stock shall no longer be deemed to be outstanding, whether or not the Corporation has received the certificates representing such shares. (b) The Corporation shall promptly send by first-class mail, postage prepaid, to each Series A Preferred Stockholder at such holder's address appearing on the Corporation's records a copy of (i) each registration statement filed by the Corporation under the Securities Act and each amendment thereof and each exhibit and schedule thereto and (ii) each order of the Securities and Exchange Commission declaring any such registration statement to be effective. 9. <PAGE> (c) Holders of Series A Preferred Stock converted into shares of Common Stock pursuant to this Section A.7 shall be entitled to payment of any accrued but unpaid cumulative dividend and any declared but unpaid dividends payable with respect to such shares of Series A Preferred Stock, up to and including the Conversion Date or the Closing Date, as the case may be. b. Mechanics of Conversion. (i) Any Series A Preferred Stockholder that exercises its right to convert its shares of Series A Preferred Stock into Common Stock shall deliver the Preferred Certificate, duly endorsed or assigned in blank to the Corporation, during regular business hours, at the office of the transfer agent of the Corporation, if any, at the principal place of business of the Corporation or at such other place as may be designated by the Corporation. (ii) Each Preferred Certificate shall be accompanied by written notice stating that such holder elects to convert such shares and stating the name or names (with address) in which the Common Certificate(s) are to be issued. Such conversion shall be deemed to have been effected on the date when the aforesaid delivery is made. (iii) As promptly as practicable thereafter, the Corporation shall issue and deliver to or upon the written order of such holder, at the place designated by such holder, the Common Certificate(s) for the number of full shares of Common Stock to which such holder is entitled and a cash payment for any fractional interest in a share of Common Stock, as provided in Section A.7(c) hereof, and for any accrued but unpaid cumulative dividends and any declared but unpaid dividends, payable with respect to the converted shares of Series A Preferred Stock, up to and including the Conversion Date or the Closing Date, as the case may be. (iv) The person in whose name each Common Certificate is to be issued shall be deemed to have become a stockholder of record of Common Stock on the Conversion Date or the Closing Date, as the case may be, unless the transfer books of the Corporation are closed on that date, in which event such holder shall be deemed to have become a stockholder of record on the next succeeding date on which the transfer books are open; provided, that the Series A Preferred Conversion Price shall be that in effect on the Conversion Date or the Closing Date, as the case may be. (v) Upon conversion of only a portion of the shares of Series A Preferred Stock covered by a Preferred Certificate, the Corporation, at its own expense, shall issue and deliver to or upon the written order of the holder of such Preferred Certificate, a new certificate representing the number of unconverted shares of Series A Preferred Stock from the Preferred Certificate so surrendered. c. Issuance of Common Stock on Conversion. (i) If a Series A Preferred Stockholder shall surrender more than one Preferred Certificate for conversion at any one time, the number of such shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Series A Preferred Stock so surrendered. 10. <PAGE> (ii) No fractional shares of Common Stock shall be issued upon conversion of shares of Series A Preferred Stock. The Corporation shall pay a cash adjustment for such fractional interest in an amount equal to the then Current Market Price of a share of Common Stock multiplied by such fractional interest. d. Conversion Price; Adjustment. The "Series A Preferred Conversion Price" with respect to the Series A Preferred Stock shall initially be equal to the Series A Preferred Original Purchase Price and shall be subject to adjustment from time to time as follows: (i) If the Corporation shall, at any time or from time to time after the Series A Preferred Original Issuance Date, make a Dilutive Issuance, the Series A Preferred Conversion Price in effect immediately prior to each such Dilutive Issuance shall automatically be lowered to a price (calculated to the nearest cent) determined by multiplying the Series A Preferred Conversion Price by a fraction, (A) the numerator of which shall be (1) the number of shares of Common Stock outstanding immediately prior to such issuance plus (2) the number of shares of Common Stock which the aggregate consideration received or to be received by the Corporation in such Dilutive Issuance so issued would purchase at the Series A Preferred Conversion Price; and (B) the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance plus the number of such additional shares of Common Stock so issued in such Dilutive Issuance; provided that, for the purpose of this Section A.7(d)(i), all shares of Common Stock issuable upon exercise or conversion of options or convertible securities outstanding immediately prior to such issuance (other than any additional shares of Common Stock issuable with respect to shares of Series Preferred Stock, convertible securities, or outstanding options, warrants or other rights for the purchase of shares of Common Stock or convertible securities, solely as a result of either (x) the Dilutive Issuance or (y) the adjustment of the Series A Preferred Conversion Price (or other conversion ratios applicable to other Series Preferred Stock and otherwise) resulting from the Dilutive Issuance) shall be deemed to be outstanding. For the purposes of any adjustment of the Series A Preferred Conversion Price pursuant to this Section A.7(d)(i), the following provisions shall be applicable: (a) In the case of the issuance of Common Stock in whole or in part for cash, the consideration shall be deemed to be the amount of cash paid therefor, plus the value of any property other than cash received by the Corporation as provided in Section A.7(d)(i)(b) hereof, less any discounts, commissions or other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with the issuance and sale thereof. (b) In the case of the issuance of Common Stock for consideration in whole or in part in property or consideration other than cash, the value of such property or consideration other than cash shall be deemed to be the fair market value thereof as determined in good faith by the Board of Directors of the Corporation, irrespective of any accounting treatment; provided, however, that such fair market value shall not exceed the aggregate Current Market Price of the shares of Common Stock being issued, less any cash consideration paid for such shares. 11. <PAGE> (c) In the case of the issuance of (I) options to purchase or rights to subscribe for Common Stock, (II) securities convertible into or exchangeable for Common Stock or (III) options to purchase or rights to subscribe for such convertible or exchangeable securities: (1) the aggregate maximum number of shares of Common Stock deliverable upon exercise of such options to purchase, or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in Sections A.7(d)(i)(a) and (b) hereof, if any, received by the Corporation upon the issuance of such options or rights plus the minimum purchase price provided in such options or rights for the Common Stock covered thereby; (2) the aggregate maximum number of shares of Common Stock deliverable upon conversion of, or in exchange for, any such convertible or exchangeable securities or upon the exercise of options to purchase, or rights to subscribe for, such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration received by the Corporation for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the additional consideration, if any, to be received by the Corporation upon the conversion or exchange of such securities or the exercise of any related options or rights (determined in the manner provided in Sections A.7(d)(i)(a) and (b) hereof); (3) if there is any decrease in the conversion or exercise price of, or any increase in the number of shares to be received upon exercise, conversion or exchange of any such options, rights or convertible or exchangeable securities (other than a change resulting from the antidilution provisions thereof), the Series A Preferred Conversion Price shall be automatically lowered to reflect such change; and (4) on the expiration of any right or option referred to in Sections A.7(d)(i)(c)(1) or (2) hereof or on the termination of any right to convert or exchange any convertible or exchangeable securities referred to in Section A.7(d)(i)(c)(2) hereof, the Series A Preferred Conversion Price then in effect shall thereupon be readjusted to the Series A Preferred Conversion Price as would have been in effect had the adjustment made upon the granting or issuance of such rights or options or convertible or exchangeable securities been made upon the basis of the issuance or sale of only the number of shares of Common Stock actually issued upon the exercise of such options or rights or upon the conversion or exchange of such convertible or exchangeable securities. (ii) If the Corporation shall at any time after the Series A Preferred Original Issuance Date fix a record date for the subdivision, split-up or stock dividend of shares of Common Stock, then, following the record date fixed for the determination of holders of Common Stock entitled to receive such subdivision, split-up or dividend (or the date of such subdivision, split-up or dividend, if no record date is fixed), the Series A Preferred Conversion Price shall be appropriately decreased so that the number of shares of Common 12. <PAGE> Stock issuable on conversion of each share of the Series A Preferred Stock shall be increased in proportion to such increase in outstanding shares. (iii) If, at any time after the Series A Preferred Original Issuance Date, the number of shares of Common Stock outstanding is decreased by a combination of the outstanding shares of Common Stock, then, following the record date fixed for such combination (or the date of such combination, if no record date is fixed), the Series A Preferred Conversion Price shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of Series A Preferred Stock shall be decreased in proportion to such decrease in outstanding shares. (iv) If, at any time after the Series A Preferred Original Issuance Date, an Extraordinary Transaction is consummated, the Series A Preferred Conversion Price with respect to the Series A Preferred Stock outstanding after the Extraordinary Transaction shall be adjusted to provide that the shares of Series A Preferred Stock outstanding immediately prior to the effectiveness of the Extraordinary Transaction shall be convertible into the kind and number of shares of stock or other securities or property of the Corporation or of the corporation resulting from or surviving such Extraordinary Transaction which the holder of the number of shares of Common Stock deliverable (immediately prior to the effectiveness of the Extraordinary Transaction) upon conversion of such Series A Preferred Stock would have been entitled to receive upon such Extraordinary Transaction. The provisions of this Section A.7(d)(iv) shall similarly apply to successive Extraordinary Transactions. (v) All calculations under this Section A.7(d) shall be made to the nearest one-tenth of a cent ($.001) or to the nearest one-tenth of a share, as the case may be. (vi) In any case in which the provisions of this Section A.7(d) shall require that an adjustment shall become effective immediately after a record date for an event, the Corporation may defer until the occurrence of that event (A) issuing to the holder of any share of Series A Preferred Stock converted after such record date and before the occurrence of such event the additional shares of capital stock issuable upon such conversion by reason of the adjustment required by such event over and above the shares of capital stock issuable upon such conversion before giving effect to such adjustment and (B) paying to such holder any amount in cash in lieu of a fractional share of capital stock pursuant to Section A.7(c) hereof; provided, however, that the Corporation shall deliver to such holder a due bill or other appropriate instrument evidencing such holder's right to receive such additional shares, in such case, upon the occurrence of the event requiring such adjustment. e. Notice of Adjustments. (i) Whenever the Series A Preferred Conversion Price shall be adjusted as provided in Section A.7(d) hereof, the Corporation shall file, at its principal office, at the office of the transfer agent for the Series A Preferred Stock, if any, or at such other place as may be designated by the Corporation, a statement, signed by its President and by its Chief Financial Officer, showing in detail the facts requiring such adjustment and the Series A Preferred Conversion Price that shall be in effect after such adjustment. The Corporation shall also cause a copy of such statement to be sent by first-class, certified mail, return receipt 13. <PAGE> requested, postage prepaid, to each Series A Preferred Stockholder at such holder's address appearing on the Corporation's records. Where appropriate, such copy may be given in advance and may be included as part of a notice required to be mailed under the provisions of Section A.7(e)(ii) hereof. (ii) In the event the Corporation shall propose to file a registration statement under the Securities Act for a Public Offering or to take any action of the types described in clauses (i), (ii), (iii) or (iv) of Section A.7(d) hereof, the Corporation shall give notice to each Series A Preferred Stockholder, in the manner set forth in Section A.7(e)(i) hereof, which shall specify the record date, if any, with respect to any such action and the date on which such action is to take place. The notice shall also set forth such facts as are reasonably necessary to indicate the effect of such action (to the extent such effect may be known at the date of such notice) on the Series A Preferred Conversion Price and the number, kind or class of shares or other securities or property which shall be deliverable or purchasable upon the occurrence of such action or deliverable upon conversion of shares of Series A Preferred Stock. In the case of any action which would require the fixing of a record date, such notice shall be given at least ten (10) days prior to the date so fixed, and in case of all other action, such notice shall be given at least fifteen (15) days prior to the taking of such proposed action. Failure to give notice under this Section A.7(e)(ii), or any defect therein, shall not affect the legality or validity of any such action. f. Transfer Taxes. The Corporation shall pay all documentary, stamp or other transactional taxes (excluding income taxes) attributable to the issuance or delivery of shares of capital stock of the Corporation upon conversion of any shares of Series A Preferred Stock; provided, however, that the Corporation shall not be required to pay any taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificate for such shares in a name other than that of the holder of the shares of Series A Preferred Stock in respect of which such shares are being issued. g. Reservation of Common Stock. The Corporation shall at all times reserve, free from preemptive rights, out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of Series A Preferred Stock, sufficient shares of Common Stock to provide for the conversion of all outstanding shares of Series A Preferred Stock. h. Status of Common Stock. All shares of Common Stock which may be issued in connection with the conversion provisions set forth herein will, upon issuance by the Corporation, be validly issued, fully paid and nonassessable, free from preemptive rights and free from all taxes, liens or charges with respect thereto created or imposed by the Corporation. 8. Redemption. a. On and after the Series B Preferred Fifth Anniversary Date or at any time if an Event of Noncompliance is declared in accordance with the Stockholders' Agreement, at the written request of the holders of shares representing not less than 75% of the combined voting power of the Series A, Series B, Series C and Series D Preferred Stock then 14. <PAGE> outstanding, voting together as a single class, made, from time to time, at any date on or after the Series B Preferred Fifth Anniversary Date or upon the declaration of an Event of Noncompliance, the Corporation shall redeem (unless otherwise prevented by law) all of the shares of Series A, Series B and Series D Preferred Stock, at a redemption price per share for each such series of Series Preferred Stock equal to (i) the Series A Preferred Original Purchase Price, the Series B Preferred Original Purchase Price or the Series D Preferred Original Purchase Price, as applicable, plus (ii) an amount equal to any accrued but unpaid cumulative dividends thereon and any declared but unpaid dividends thereof, and, then, all of the shares of Series C Preferred Stock, at a redemption price per share for such Series C Preferred Stock equal to (i) the Series C Preferred Original Purchase Price plus (ii) an amount equal to any accrued but unpaid dividends thereon and any declared but unpaid dividends thereon. For purposes of determining whether the requisite 75% of the holders of Series A, Series B, Series C and Series D Preferred Stock are participating in the Redemption Notice, each share of issued and outstanding Series A, Series B, Series C and Series D Preferred Stock shall entitle the holder thereof to one vote per share for each share of Common Stock (including fractional shares) into which each share of Series A, Series B, Series C and Series D Preferred Stock is then convertible, rounded to the nearest one-tenth of a share. b. On and after the Redemption Date, all rights of any Series A Preferred Stockholder with respect to the shares of Series A Preferred Stock redeemed on that Redemption Date, except the right to receive the Redemption Payment as provided herein, shall cease, and such shares shall no longer be deemed to be outstanding, whether or not the Corporation has received the certificates representing such shares, on the condition that the Corporation pays the Redemption Payment, or irrevocably deposits or sets aside cash in an amount equal to the Redemption Payment; provided, however, that if the Corporation defaults in the payment of the Redemption Payment, the rights of the holder with respect to such shares of Series A Preferred Stock shall continue until the Corporation cures such default. c. The Requesting Holders shall send their Redemption Notice pursuant to this Section A.8 by first-class, certified mail, return receipt requested, postage prepaid, to the Corporation at its principal place of business or to any transfer agent of the Corporation. The Corporation shall fix a date for redemption which shall not be more than 60 days after the receipt of Redemption Notices from the Requesting Holders. Not less than 45 days prior to the Redemption Date, written notice shall be mailed, first class postage prepaid, to each holder of record (at the close of business on the business day next preceding the day on which notice is given) of the Series A, Series B, Series C and Series D Preferred Stock, at the address last shown on the records of the Corporation for such holder or given by the holder to the Corporation for the purpose of notice, notifying such holder of the redemption to be effected, the Redemption Date fixed, the Redemption Payment, the place at which payment may be obtained and the date on which such holder's conversion rights as to such shares terminate and calling upon such holder to surrender to the Corporation, in the manner and at the place designated, such holder's certificate or certificates representing the shares to be redeemed. In the event of only a partial redemption of the outstanding shares of the Series A, Series B and Series D Preferred Stock entitled to redemption for any reason, the redemption of the Series A, Series B and Series D Preferred Stock shall be pro rata based upon the total amount that would be paid by the Corporation to each Series A, Series B and Series D Preferred Stockholder if all of the shares of Series A, Series B and Series D Preferred Stock were fully redeemed pursuant to Sections 15. <PAGE> A.8(a), B.8(a) and D.8(a) hereof. At any time on or after the Redemption Date, the holders of the Series A Preferred Stock shall be entitled to receive the Redemption Payment for each of the shares of Series A Preferred Stock held by such holder which are to be redeemed by the Corporation upon actual delivery to the Corporation or its transfer agent of the certificate(s) representing the shares to be redeemed. Upon redemption of only a portion of the number of shares covered by a Series A Preferred Stock certificate, the Corporation shall issue and deliver to or upon the written order of the holder of such Series A Preferred Stock certificate, at the expense of the Corporation, a new certificate covering the number of shares of Series A Preferred Stock being redeemed representing the unredeemed portion of the Series A Preferred Stock certificate, which new certificate shall entitle the holder thereof to all the rights, powers and privileges of a holder of such shares. d. Notwithstanding anything to the contrary contained in this Section A.8, the Corporation shall not be obligated to acquire any shares on any Redemption Date to the extent that the acquisition thereof would violate any law, statute, rule, regulation, policy or guideline promulgated by any federal, state, local or foreign governmental authority applicable to the Corporation, provided that the Corporation shall use all legally permissible methods in the reduction of capital and revaluation of assets, including appraisal, in order to obtain a legal source of funds with which to pay the Redemption Payment and shall acquire such shares as soon as permitted by applicable laws, statutes, rules, regulations, policies and guidelines. 9.

Whenever any dividend or other distribution is declared on any shares of Series B Preferred Stock, the Board of Directors shall simultaneously declare a dividend or distribution at the same percentage rate and in the same form on each other outstanding share of Series B Preferred Stock and each outstanding share of the Series A and Series D Preferred Stock, so that all outstanding shares of Series A, Series B and Series D Preferred Stock will participate equally with each other ratably per share. b. So long as any Series B Preferred Stock is outstanding the Corporation shall not declare or pay any dividend or make any distribution (whether in cash, shares of capital stock of the Corporation or other property) on shares of its Common Stock or any other class or series of stock ranking pari passu with or junior to the Series B Preferred Stock, unless prior thereto or simultaneously therewith (A) all dividends and distributions previously declared on the Series B Preferred Stock and (B) any cumulative dividends in accordance with Section B.3(d) hereof shall have been paid or the Corporation shall have irrevocably deposited or set aside cash or United States Obligations sufficient for the payment thereof. c. If the Board of Directors declares dividends or other distributions (other than on Liquidation) on the Common Stock or any other class or series of stock ranking pari passu with or junior to the Series B Preferred Stock in cash, property or securities (excluding Common Stock) of the Corporation (or subscription or other rights to purchase or acquire securities (excluding Common Stock) of the Corporation), the Board of Directors shall simultaneously declare a dividend or distribution on the same terms, at the same or equivalent rate, and in the same form on each share of Series B Preferred Stock, so that all outstanding shares of Series B Preferred Stock will participate ratably with the shares of Common Stock and the shares of each other class or series of stock ranking pari passu with or junior to the Series B Preferred Stock in such dividend or distribution. For purposes of determining its proportional share of the dividend or distribution, each share of the Series B Preferred Stock and any other applicable class or series of convertible securities shall be deemed to be that number of shares of Common Stock into which such share is then convertible, rounded to the nearest one-tenth of a share. d. From and after the Series A Preferred Fifth Anniversary Date and until the date of the consummation of the Corporation's first Public Offering, the Series B Preferred Stock will be entitled, pari passu with the Series A and Series D Preferred Stock, to dividends, to be paid quarterly, in cash or in kind at the discretion of the Board of Directors, at an annual rate of five percent (5%) of the Series B Preferred Original Purchase Price (or such greater amount of dividends as such Series B Preferred Stock would be entitled to if such Series B Preferred Stock were converted into Common Stock), as adjusted for any combinations or 17. <PAGE> divisions or similar recapitalizations affecting the Series B Preferred Stock after the Series B Preferred Original Issuance Date, payable on the first day of January, April, July and October (and any dividends payable to holders of Series B Preferred Stock which are not paid shall be cumulative). Upon conversion of any Series B Preferred Stock, all accrued but unpaid cumulative dividends and any declared but unpaid dividends shall be paid in cash, or in additional shares of Common Stock at the Series B Preferred Conversion Price then in effect in the discretion of the Board of Directors. Nothing in this Section B.3(d) shall be deemed to limit the rights of the Series B Preferred Stock under Sections B.3(b) and B.3(c) hereof. 4. Rights on Liquidation, Dissolution, Winding-Up. a. With respect to rights on Liquidation, the Series B Preferred Stock shall rank (x) pari passu with the Series A and Series D Preferred Stock, (y) senior and prior to the Series C Preferred Stock and Series E Preferred Stock (but only to the extent provided in this Section B.4) and (z) senior and prior to the Common Stock and to all other classes or series of stock issued by the Corporation, except in the case of a change in the relative ranking upon Liquidation of the Series A, Series B and Series D Preferred Stock, as otherwise approved by the affirmative vote or consent of the holders of 75% of the issued and outstanding shares of Series A, Series B and Series D Preferred Stock voting together. b. In the event of any Liquidation, whether voluntary or involuntary, before any payment of cash or distribution of other property shall be made to the Series C Preferred Stockholders, Series E Preferred Stockholders or the Common Stockholders or any other class or series of stock ranking on Liquidation junior to the Series B Preferred Stock, the holders of Series B Preferred Stock shall be entitled to receive out of the assets of the Corporation legally available for distribution to its stockholders, pari passu with the rights of the Series A and Series D Preferred Stockholders, an amount per share equal to the Series B Preferred Original Purchase Price whether from capital, surplus or earnings, plus an amount equal to any accrued but unpaid cumulative dividends thereon and any declared but unpaid dividends thereon. c. If, upon any Liquidation, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the Series B Preferred Stockholders the full amounts to which each of them shall be entitled pursuant to Section B.4(b) hereof and to pay to the Series A and Series D Preferred Stockholders the full amount to which each of them shall be entitled pursuant to Sections A.4(b) and D.4(b) hereof, then the Series A, Series B and Series D Preferred Stockholders shall share ratably in any distribution of assets according to the respective amounts which would be payable to them in respect of the shares of Series A, Series B or Series D Preferred Stock, as the case may be, held upon such distribution if all amounts payable on or with respect to such shares were paid in full pursuant to Sections A.4(b), B.4(b) and D.4(b) hereof. d. In the event of any Liquidation, after payment shall have been made to (i) the Series A, Series B and Series D Preferred Stockholders of the full amount to which they shall be entitled pursuant to Sections A.4(b), B.4(b) and D.4(b) hereof, respectively, and (ii) the Series C and Series E Preferred Stockholders of the full amount to which they shall be entitled pursuant to Section C.4(b) and E.4(b) hereof, respectively, with respect to each other 18. <PAGE> class or series of capital stock (other than the Series C Preferred Stock, Series E Preferred Stock and the Common Stock) ranking on Liquidation junior to such Series B Preferred Stock (in descending order of seniority), the Series A, Series B and Series D Preferred Stockholders, as a class shall be entitled to receive an amount equal (and in like kind) to the aggregate preferential amount fixed for each such junior class or series of capital stock, which amount shall be distributed ratably among the Series A Preferred Stockholders in an equal amount per share of the Series A Preferred Stock then outstanding, among the Series B Preferred Stockholders in an equal amount per share of the Series B Preferred Stock then outstanding and among the Series D Preferred Stockholders in an equal amount per share of the Series D Preferred Stock then outstanding. If, upon any Liquidation, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the Series A Preferred Stockholders, Series B Preferred Stockholders, the Series D Preferred Stockholders, and each class or series of capital stock (other than the Series C Preferred Stock, Series E Preferred Stock and the Common Stock) junior to the Series B Preferred Stock the full amounts to which they shall be entitled pursuant to the immediately preceding sentence, the Series A, Series B and Series D Preferred Stockholders shall be entitled to share ratably with each such other class or series of capital stock in any distribution of assets according to the respective preferential amounts fixed for the Series A Preferred Stock (pursuant to Section A.4(b) hereof), the Series B Preferred Stock (pursuant to Section B.4(b) hereof) and the Series D Preferred Stock (pursuant to Section D.4(b) hereof) and each such junior class or series of capital stock (pursuant to the applicable terms thereof), which would be payable in respect of the shares held by them upon such distribution if all such preferential amounts payable on or with respect to such shares were paid in full. e. In the event of any Liquidation, after payment shall have been made to the Series A Preferred Stockholders, the Series B Preferred Stockholders, the Series C Preferred Stockholders, Series D Preferred Stockholders and the Series E Preferred Stockholders of the full amount to which they shall be entitled as aforesaid, and after payment shall have made of the respective preferential amounts of all other classes and series of capital stock ranking senior to the Common Stock, the Series A, Series B and Series D Preferred Stockholders shall be entitled to share ratably (calculated with respect to such Series A, Series B and Series D Preferred Stock as provided in the next sentence) with the holders of Common Stock in all remaining assets of the Corporation available for distribution to its stockholders. For purposes of calculating the amount of any payment to be paid pursuant to this Section B.4(e) upon any such Liquidation, each share of Series A, Series B and Series D Preferred Stock shall be deemed to be that number of shares of Common Stock into which such share is then convertible, rounded to the nearest one-tenth of a share. 5. Merger, Consolidation, etc. a. In the event the Corporation intends to sell, lease or otherwise dispose of all or substantially all of the assets of the Corporation, effect any transaction or series of related transactions in which more than 50% of the voting power of the Corporation is transferred (other than in connection with a Public Offering), or merge or consolidate with or into any other corporation, corporations or other entity or entities (other than a merger or consolidation in which the Series Preferred Stockholders receive securities of the surviving corporation having substantially similar rights to the Series Preferred Stock and in which the stockholders of the Corporation immediately prior to such a transaction are holders of at least a 19. <PAGE> majority of the voting securities of the surviving corporation immediately thereafter), then the Corporation shall give written notice to each Series Preferred Stockholder no less than 20 days prior to the closing of any such transaction notifying the Series Preferred Stockholders of the terms and timing of the closing of such transaction and of the rights of the Series Preferred Stockholders under Sections A.5(b), B.5(b), C.5(b), D.5(b) and E.5(b) hereof. b. Upon the affirmative vote of the holders of not less than 75% in voting power of all of the shares of Series Preferred Stock then outstanding, voting together as a separate class, made prior to the consummation of such transaction, the proceeds of or any property deliverable from such transaction shall be distributed among the holders of the Series Preferred Stock and the Common Stock according to the provisions of Sections A.4, B.4, C.4, D.4 and E.4 hereof as if such transaction were a Liquidation. c. The voting rights of the holders of Series Preferred Stock contained in Sections A.5(b), B.5(b), C.5(b), D.5(b) and E.5(b) hereof may be exercised at a special meeting of the holders of Series Preferred Stockholders called as provided in accordance with the By-laws of the Corporation or by written consent of the holders of Series Preferred Stock in lieu of a meeting. 6. Voting. a. General. In addition to the rights otherwise provided for herein or by law, the Series B Preferred Stockholders shall be entitled to vote, together with the Series A Preferred Stockholders, the Series C Preferred Stockholders, the Series D Preferred Stockholders, the Series E Preferred Stockholders and the Common Stockholders and any other class or series of stock then entitled to vote, as one class on all matters as to which Common Stockholders shall be entitled to vote, in the same manner and with the same effect as the Common Stockholders, except as otherwise required by the General Corporation Law. In any such vote, and in any vote or action of the Series B Preferred Stockholders voting together as a separate class or with the other holders of Series Preferred Stock as a separate class, each share of issued and outstanding Series B Preferred Stock shall entitle the holder thereof to one vote per share for each share of Common Stock (including fractional shares) into which each share of Series B Preferred Stock is then convertible, rounded to the nearest one-tenth of a share. b. Election of Board of Directors. (i) In addition to the rights specified in Sections A.6(a), B.6(a), C.6(a) and D.6(a) hereof, the holders of a majority in voting power of the Series A, Series B, Series C and Series D Preferred Stock, voting together as a separate class or in such other manner as the holders of the Series A, Series B, Series C and Series D Preferred Stock shall agree among themselves in the Stockholders' Agreement, shall have the exclusive right to elect to the Board of Directors of the Corporation that number of directors which shall be equal to a majority of the total number of directors on the Board of Directors at any given time. In any election of Preferred Directors pursuant to this Section B.6(b) and Sections A.6(b), C.6(b) and D.6(b), each share of issued and outstanding Series A, Series B, Series C and Series D Preferred Stock shall entitle the holder thereof to the number of votes per share that equals the number of shares of Common Stock (including fractional shares) into which each such share is then 20. <PAGE> convertible, rounded up to the nearest one-tenth of a share. The voting rights of the Series A, Series B, Series C and Series D Preferred Stockholders contained in this Section B.6(b) and Sections A.6(b), C.6(b) and D.6(b) may be exercised at a special meeting of the Series Preferred Stockholders called as provided in accordance with the By-laws of the Corporation, at any annual or special meeting of the Stockholders of the Corporation, or by written consent of the holders of Series Preferred Stock in lieu of a meeting. The Preferred Directors elected pursuant to this Section B.6(b) and Sections A.6(b), C.6(b) and D.6(b) shall serve from the date of their election and qualification until their successors have been duly elected and qualified. (ii) Notwithstanding anything to the contrary contained in Sections A.6(b)(i), B.6(b)(i), C.6(b)(i) and D.6(b)(i) hereof, if an Event of Noncompliance is declared in accordance with the Stockholders' Agreement, the Series A, Series B, Series C and Series D Preferred Stockholders, voting together as a separate class, shall have the right to elect all of the members of the Board of Directors of the Corporation. (iii) A vacancy in the directorships to be elected pursuant to Sections A.6(b)(i)-(ii), B.6(b)(i)-(ii), C.6(b)(i)-(ii) and D.6(b)(i)-(ii) hereof (including any vacancy created on account of an increase in the number of directors on the Board of Directors) may be filled only by vote at a meeting called in accordance with the By-laws of the Corporation or written consent in lieu of a meeting in accordance with Sections A.6(b)(i), B.6(b)(i), C.6(b)(i) and D.6(b)(i) hereof or, with respect to a Preferred Director, as provided for in the Stockholders' Agreement. c. Protective Provisions. So long as any Series Preferred Stock is outstanding, the Corporation shall not, without the written consent in lieu of a meeting, or the affirmative vote at a meeting called for such purpose, of the holders of shares representing at least 75% of the combined voting power of the issued and outstanding Series A, Series B, Series C, Series D and Series E Preferred Stock, voting together as a single class: (i) except for "Excluded Stock", authorize, issue or agree to authorize or issue any shares of capital stock of the Corporation, any right, warrant, or option to receive any capital stock, or any security convertible into or exchangeable for capital stock or any capitalized lease with any equity feature with respect to the capital stock of the Corporation; (ii) change as a whole, by subdivision or combination in any manner, the number of shares of the Common Stock then outstanding into a different number of shares, with or without par value, without making the identical change as a whole in the number of shares of Series Preferred Stock then outstanding; (iii) amend, alter or repeal, in any manner whatsoever, the designations, powers, preferences, relative, participating, optional or other special rights, qualifications, limitations and restrictions of the Series Preferred Stock; (iv) sell, abandon, transfer, lease or otherwise dispose of all or substantially all of the properties or assets of the Corporation or any of its subsidiaries; (v) declare or pay any dividend (other than as required by Section A.3(d) hereof in respect of the Series A Preferred Stock, by Section B.3(d) hereof in 21. <PAGE> respect of the Series B Preferred Stock and by Section D.3(d) hereof in respect of the Series D Preferred Stock) or make any distribution (whether in cash, shares of capital stock of the Corporation, or other property) on shares of its capital stock other than the Series Preferred Stock; (vi) merge or consolidate with or into, or permit any subsidiary of the Corporation to merge or consolidate with or into, any other corporation, corporations or other entity or entities, or effect any transaction or series of related transactions in which more than 50% of the voting power of the Corporation is transferred (other than in connection with a Public Offering); (vii) voluntarily dissolve, liquidate or wind-up or carry out any partial Liquidation or distribution or transaction in the nature of a partial Liquidation or distribution; (viii) increase the number of shares of any series of Preferred Stock of the Corporation authorized to be issued; (ix) reclassify any shares of the Corporation's capital stock as shares ranking senior to or on parity with the Series Preferred Stock with respect to rights on Liquidation, redemption or for the payment of any dividend or distribution other than in Liquidation; (x) amend, alter or repeal any provision of the Certificate of Incorporation of the Corporation; (xi) amend, alter or repeal any provisions of the By-laws of the Corporation so as to adversely affect the rights of the holders of the Series Preferred Stock; or (xii) directly or indirectly, redeem, purchase or otherwise acquire for value (including through an exchange), or set apart money or other property for any mandatory purchase or other analogous fund for the redemption, purchase or acquisition of, any shares of Common Stock, except (a) pursuant to Sections A.8, B.8, C.8 and D.8 hereof, and (b) pursuant to any agreement approved by the Board of Directors with an officer, director, employee or consultant providing for the repurchase of any capital stock of the Corporation owned by such officer, director, employee or consultant at the option of the Corporation, which is either (A) set forth on Schedule 4.10 of the Series B Stock Purchase Agreement, or (B) issued pursuant to the Option Plan, as amended, the 1997 Equity Incentive Plan, or any other stock option plan of the Corporation or one or more amendments to the Option Plan, from and after May 13, 1996, approved by the Board of Directors and by the holders of 75% of the then issued and outstanding Series Preferred Stock, voting together as a separate class. In any vote or written consent in lieu of a meeting pursuant to this Section B.6(c) and Sections A.6(c), C.6(c), D.6(c) and E.6(c) hereof, each share of issued and outstanding Series Preferred Stock shall entitle the holder thereof to the number of votes per share that equals the number of shares of Common Stock (including fractional shares) into which each such share is then convertible, rounded to the nearest one-tenth of a share. 22. <PAGE> 7. Conversion. a. Right to Convert. (i) Any Series B Preferred Stockholder shall have the right, at any time or from time to time, prior to the Closing Date to convert any or all of its shares of Series B Preferred Stock into that number of fully paid and nonassessable shares of Common Stock for each share of Series B Preferred Stock so converted equal to the quotient of the Series B Preferred Original Purchase Price divided by the Series B Preferred Conversion Price (as last adjusted and then in effect) rounded to the nearest one-tenth of a share. (ii) (a) Any Series B Preferred Stock that remains unconverted on the Closing Date shall be automatically converted without notice and without any action on the part of the holder thereof into shares of Common Stock on the Closing Date in accordance with the preceding sentence. After the Closing Date all rights of holders of shares of Series B Preferred Stock with respect to Series B Preferred Stock, except the right to receive shares of Common Stock in accordance with this Section B.7(a)(ii)(a) and any accrued but unpaid dividends and any declared but unpaid dividends as in accordance with Section B.7(a)(ii)(c) hereof, shall cease and the shares of Series B Preferred Stock shall no longer be deemed to be outstanding, whether or not the Corporation has received the certificates representing such shares. (b) The Corporation shall promptly send by first-class mail, postage prepaid, to each Series B Preferred Stockholder at such holder's address appearing on the Corporation's records a copy of (i) each registration statement filed by the Corporation under the Securities Act and each amendment thereof and each exhibit and schedule thereto and (ii) each order of the Securities and Exchange Commission declaring any such registration statement to be effective. (c) Holders of Series B Preferred Stock converted into shares of Common Stock pursuant to this Section B.7 shall be entitled to payment of any accrued but unpaid cumulative dividend and any declared but unpaid dividends payable with respect to such shares of Series B Preferred Stock, up to and including the Conversion Date or the Closing Date, as the case may be. b. Mechanics of Conversion. (i) Any Series B Preferred Stockholder that exercises its right to convert its shares of Series B Preferred Stock into Common Stock shall deliver the Preferred Certificate, duly endorsed or assigned in blank to the Corporation, during regular business hours, at the office of the transfer agent of the Corporation, if any, at the principal place of business of the Corporation or at such other place as may be designated by the Corporation. (ii) Each Preferred Certificate shall be accompanied by written notice stating that such holder elects to convert such shares and stating the name or names (with address) in which the Common Certificate(s) are to be issued. Such conversion shall be deemed to have been effected on the date when the aforesaid delivery is made. 23. <PAGE> (iii) As promptly as practicable thereafter, the Corporation shall issue and deliver to or upon the written order of such holder, at the place designated by such holder, the Common Certificate(s) for the number of full shares of Common Stock to which such holder is entitled and a cash payment for any fractional interest in a share of Common Stock, as provided in Section B.7(c) hereof, and for any accrued but unpaid cumulative dividends and any declared but unpaid dividends, payable with respect to the converted shares of Series B Preferred Stock, up to and including the Conversion Date or the Closing Date, as the case may be. (iv) The person in whose name each Common Certificate is to be issued shall be deemed to have become a stockholder of record of Common Stock on the Conversion Date or the Closing Date, as the case may be, unless the transfer books of the Corporation are closed on that date, in which event such holder shall be deemed to have become a stockholder of record on the next succeeding date on which the transfer books are open; provided, that the Series B Preferred Conversion Price shall be that in effect on the Conversion Date or the Closing Date, as the case may be. (v) Upon conversion of only a portion of the shares of Series B Preferred Stock covered by a Preferred Certificate, the Corporation, at its own expense, shall issue and deliver to or upon the written order of the holder of such Preferred Certificate, a new certificate representing the number of unconverted shares of Series B Preferred Stock from the Preferred Certificate so surrendered. c. Issuance of Common Stock on Conversion. (i) If a Series B Preferred Stockholder shall surrender more than one Preferred Certificate for conversion at any one time, the number of such shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Series B Preferred Stock so surrendered. (ii) No fractional shares of Common Stock shall be issued upon conversion of shares of Series B Preferred Stock. The Corporation shall pay a cash adjustment for such fractional interest in an amount equal to the then Current Market Price of a share of Common Stock multiplied by such fractional interest. d. Conversion Price; Adjustment. The "Series B Preferred Conversion Price" with respect to the Series B Preferred Stock shall initially be equal to the Series B Preferred Original Purchase Price and shall be subject to adjustment from time to time as follows: (i) If the Corporation shall, at any time or from time to time after the Series B Preferred Original Issuance Date, make a Dilutive Issuance, the Series B Preferred Conversion Price in effect immediately prior to each such Dilutive Issuance shall automatically be lowered to a price (calculated to the nearest cent) determined by multiplying the Series B Preferred Conversion Price by a fraction, (A) the numerator of which shall be (1) the number of shares of Common Stock outstanding immediately prior to such issuance plus (2) the number of shares of Common Stock which the aggregate consideration received or to be received by the Corporation in such Dilutive Issuance so issued would purchase at the Series B Preferred 24. <PAGE> Conversion Price; and (B) the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance plus the number of such additional shares of Common Stock so issued in such Dilutive Issuance; provided that, for the purpose of this Section B.7(d)(i), all shares of Common Stock issuable upon exercise or conversion of options or convertible securities outstanding immediately prior to such issuance (other than any additional shares of Common Stock issuable with respect to shares of Series Preferred Stock, convertible securities, or outstanding options, warrants or other rights for the purchase of shares of Common Stock or convertible securities, solely as a result of either (x) the Dilutive Issuance or (y) the adjustment of the Series B Preferred Conversion Price (or other conversion ratios applicable to other Series Preferred Stock and otherwise) resulting from the Dilutive Issuance) shall be deemed to be outstanding. For the purposes of any adjustment of the Series B Preferred Conversion Price pursuant to this Section B.7(d)(i), the following provisions shall be applicable: (a) In the case of the issuance of Common Stock in whole or in part for cash, the consideration shall be deemed to be the amount of cash paid therefor, plus the value of any property other than cash received by the Corporation as provided in Section B.7(d)(i)(b) hereof, less any discounts, commissions or other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with the issuance and sale thereof. (b) In the case of the issuance of Common Stock for consideration in whole or in part in property or consideration other than cash, the value of such property or consideration other than cash shall be deemed to be the fair market value thereof as determined in good faith by the Board of Directors of the Corporation, irrespective of any accounting treatment; provided, however, that such fair market value shall not exceed the aggregate Current Market Price of the shares of Common Stock being issued, less any cash consideration paid for such shares. (c) In the case of the issuance of (I) options to purchase or rights to subscribe for Common Stock, (II) securities convertible into or exchangeable for Common Stock or (III) options to purchase or rights to subscribe for such convertible or exchangeable securities: (1) the aggregate maximum number of shares of Common Stock deliverable upon exercise of such options to purchase, or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in Sections B.7(d)(i)(a) and (b) hereof, if any, received by the Corporation upon the issuance of such options or rights plus the minimum purchase price provided in such options or rights for the Common Stock covered thereby; (2) the aggregate maximum number of shares of Common Stock deliverable upon conversion of, or in exchange for, any such convertible or exchangeable securities or upon the exercise of options to purchase, or rights to subscribe for, such convertible or exchangeable securities and subsequent conversion or exchange thereof shall 25. <PAGE> be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration received by the Corporation for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the additional consideration, if any, to be received by the Corporation upon the conversion or exchange of such securities or the exercise of any related options or rights (determined in the manner provided in Sections B.7(d)(i)(a) and (b) hereof); 3. if there is any decrease in the conversion or exercise price of, or any increase in the number of shares to be received upon exercise, conversion or exchange of any such options, rights or convertible or exchangeable securities (other than a change resulting from the antidilution provisions thereof), the Series B Preferred Conversion Price shall be automatically lowered to reflect such change; and 4. on the expiration of any right or option referred to in Sections B.7(d)(i)(c)(1) or (2) hereof or on the termination of any right to convert or exchange any convertible or exchangeable securities referred to in Section B.7(d)(i)(c)(2) hereof, the Series B Preferred Conversion Price then in effect shall thereupon be readjusted to the Series B Preferred Conversion Price as would have been in effect had the adjustment made upon the granting or issuance of such rights or options or convertible or exchangeable securities been made upon the basis of the issuance or sale of only the number of shares of Common Stock actually issued upon the exercise of such options or rights or upon the conversion or exchange of such convertible or exchangeable securities. (ii) If the Corporation shall at any time after the Series B Preferred Original Issuance Date fix a record date for the subdivision, split-up or stock dividend of shares of Common Stock, then, following the record date fixed for the determination of holders of Common Stock entitled to receive such subdivision, split-up or dividend (or the date of such subdivision, split-up or dividend, if no record date is fixed), the Series B Preferred Conversion Price shall be appropriately decreased so that the number of shares of Common Stock issuable on conversion of each share of the Series B Preferred Stock shall be increased in proportion to such increase in outstanding shares. (iii) If, at any time after the Series B Preferred Original Issuance Date, the number of shares of Common Stock outstanding is decreased by a combination of the outstanding shares of Common Stock, then, following the record date fixed for such combination (or the date of such combination, if no record date is fixed), the Series B Preferred Conversion Price shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of Series B Preferred Stock shall be decreased in proportion to such decrease in outstanding shares. (iv) If, at any time after the Series B Preferred Original Issuance Date, an Extraordinary Transaction is consummated, the Series B Preferred Conversion Price with respect to the Series B Preferred Stock outstanding after the Extraordinary Transaction shall be adjusted to provide that the shares of Series B Preferred Stock outstanding immediately prior to the effectiveness of the Extraordinary Transaction shall be convertible into the kind and number of shares of stock or other securities or property of the Corporation or of the corporation resulting from or surviving such Extraordinary Transaction which the holder of the 26. <PAGE> number of shares of Common Stock deliverable (immediately prior to the effectiveness of the Extraordinary Transaction) upon conversion of such Series B Preferred Stock would have been entitled to receive upon such Extraordinary Transaction. The provisions of this Section B.7(d)(iv) shall similarly apply to successive Extraordinary Transactions. (v) All calculations under this Section B.7(d) shall be made to the nearest one-tenth of a cent ($.001) or to the nearest one-tenth of a share, as the case may be. (vi) In any case in which the provisions of this Section B.7(d) shall require that an adjustment shall become effective immediately after a record date for an event, the Corporation may defer until the occurrence of that event (A) issuing to the holder of any share of Series B Preferred Stock converted after such record date and before the occurrence of such event the additional shares of capital stock issuable upon such conversion by reason of the adjustment required by such event over and above the shares of capital stock issuable upon such conversion before giving effect to such adjustment and (B) paying to such holder any amount in cash in lieu of a fractional share of capital stock pursuant to Section B.7(c) hereof; provided, however, that the Corporation shall deliver to such holder a due bill or other appropriate instrument evidencing such holder's right to receive such additional shares, in such case, upon the occurrence of the event requiring such adjustment. e. Notice of Adjustments. (i) Whenever the Series B Preferred Conversion Price shall be adjusted as provided in Section B.7(d) hereof, the Corporation shall file, at its principal office, at the office of the transfer agent for the Series B Preferred Stock, if any, or at such other place as may be designated by the Corporation, a statement, signed by its President and by its Chief Financial Officer, showing in detail the facts requiring such adjustment and the Series B Preferred Conversion Price that shall be in effect after such adjustment. The Corporation shall also cause a copy of such statement to be sent by first-class, certified mail, return receipt requested, postage prepaid, to each Series B Preferred Stockholder at such holder's address appearing on the Corporation's records. Where appropriate, such copy may be given in advance and may be included as part of a notice required to be mailed under the provisions of Section B.7(e)(ii) hereof. (ii) In the event the Corporation shall propose to file a registration statement under the Securities Act for a Public Offering or to take any action of the types described in clauses (i), (ii), (iii) or (iv) of Section B.7(d) hereof, the Corporation shall give notice to each Series B Preferred Stockholder, in the manner set forth in Section B.7(e)(i) hereof, which shall specify the record date, if any, with respect to any such action and the date on which such action is to take place. The notice shall also set forth such facts as are reasonably necessary to indicate the effect of such action (to the extent such effect may be known at the date of such notice) on the Series B Preferred Conversion Price and the number, kind or class of shares or other securities or property which shall be deliverable or purchasable upon the occurrence of such action or deliverable upon conversion of shares of Series B Preferred Stock. In the case of any action which would require the fixing of a record date, such notice shall be given at least ten (10) days prior to the date so fixed, and in case of all other action, such notice shall be given at least fifteen (15) days prior to the taking of such proposed action. Failure to give notice under 27. <PAGE> this Section B.7(e)(ii), or any defect therein, shall not affect the legality or validity of any such action. f. Transfer Taxes. The Corporation shall pay all documentary, stamp or other transactional taxes (excluding income taxes) attributable to the issuance or delivery of shares of capital stock of the Corporation upon conversion of any shares of Series B Preferred Stock; provided, however, that the Corporation shall not be required to pay any taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificate for such shares in a name other than that of the holder of the shares of Series B Preferred Stock in respect of which such shares are being issued. g. Reservation of Common Stock. The Corporation shall at all times reserve, free from preemptive rights, out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of Series B Preferred Stock, sufficient shares of Common Stock to provide for the conversion of all outstanding shares of Series B Preferred Stock. h. Status of Common Stock. All shares of Common Stock which may be issued in connection with the conversion provisions set forth herein will, upon issuance by the Corporation, be validly issued, fully paid and nonassessable, free from preemptive rights and free from all taxes, liens or charges with respect thereto created or imposed by the Corporation. 8. Redemption. a. On and after the Series B Preferred Fifth Anniversary Date or at any time if an Event of Noncompliance is declared in accordance with the Stockholders' Agreement, at the written request of the holders of shares representing not less than 75% of the combined voting power of the Series A, Series B, Series C and Series D Preferred Stock then outstanding, voting together as a single class, made, from time to time, at any date on or after the Series B Preferred Fifth Anniversary Date or upon the declaration of an Event of Noncompliance, the Corporation shall redeem (unless otherwise prevented by law) all of the shares of Series A, Series B and Series D Preferred Stock, at a redemption price per share for each such series of Series Preferred Stock equal to (i) the Series A Preferred Original Purchase Price, Series B Preferred Original Purchase Price or Series D Preferred Original Purchase Price, as applicable, plus (ii) an amount equal to any accrued but unpaid cumulative dividends thereon and any declared but unpaid dividends thereof, and, then, all of the shares of Series C Preferred Stock, at a redemption price per share for such Series C Preferred Stock equal to (i) the Series C Preferred Original Purchase Price plus (ii) an amount equal to any accrued but unpaid dividends thereon and any declared but unpaid dividends thereon. For purposes of determining whether the requisite 75% of the holders of Series A, Series B, Series C and Series D Preferred Stock are participating in the Redemption Notice, each share of issued and outstanding Series A, Series B, Series C and Series D Preferred Stock shall entitle the holder thereof to one vote per share for each share of Common Stock (including fractional shares) into which each share of Series A, Series B, Series C and Series D Preferred Stock is then convertible, rounded to the nearest one-tenth of a share. 28. <PAGE> b. On and after the Redemption Date, all rights of any Series B Preferred Stockholder with respect to the shares of Series B Preferred Stock redeemed on that Redemption Date, except the right to receive the Redemption Payment as provided herein, shall cease, and such shares shall no longer be deemed to be outstanding, whether or not the Corporation has received the certificates representing such shares, on the condition that the Corporation pays the Redemption Payment, or irrevocably deposits or sets aside cash in an amount equal to the Redemption Payment; provided, however, that if the Corporation defaults in the payment of the Redemption Payment, the rights of the holder with respect to such shares of Series B Preferred Stock shall continue until the Corporation cures such default. c. The Requesting Holders shall send their Redemption Notice pursuant to this Section B.8 by first-class, certified mail, return receipt requested, postage prepaid, to the Corporation at its principal place of business or to any transfer agent of the Corporation. The Corporation shall fix a date for redemption which shall not be more than 60 days after the receipt of Redemption Notices from the Requesting Holders. Not less than 45 days prior to the Redemption Date, written notice shall be mailed, first class postage prepaid, to each holder of record (at the close of business on the business day next preceding the day on which notice is given) of the Series A, Series B, Series C and Series D Preferred Stock, at the address last shown on the records of the Corporation for such holder or given by the holder to the Corporation for the purpose of notice, notifying such holder of the redemption to be effected, the Redemption Date fixed, the Redemption Payment, the place at which payment may be obtained and the date on which such holder's conversion rights as to such shares terminate and calling upon such holder to surrender to the Corporation, in the manner and at the place designated, such holder's certificate or certificates representing the shares to be redeemed. In the event of only a partial redemption of the outstanding shares of the Series A, Series B and Series D Preferred Stock entitled to redemption for any reason, the redemption of the Series A, Series B and Series D Preferred Stock shall be pro rata based upon the total amount that would be paid by the Corporation to each Series A, Series B and Series C Preferred Stockholder if all of the Series A, Series B and Series C Preferred Stock were fully redeemed pursuant to Sections A.8(a), B.8(a) and D.8(a) hereof. At any time on or after the Redemption Date, the holders of the Series B Preferred Stock shall be entitled to receive the Redemption Payment for each of the shares of Series B Preferred Stock held by such holder which are to be redeemed by the Corporation upon actual delivery to the Corporation or its transfer agent of the certificate(s) representing the shares to be redeemed. Upon redemption of only a portion of the number of shares covered by a Series B Preferred Stock certificate, the Corporation shall issue and deliver to or upon the written order of the holder of such Series B Preferred Stock certificate, at the expense of the Corporation, a new certificate covering the number of shares of Series B Preferred Stock being redeemed representing the unredeemed portion of the Series B Preferred Stock certificate, which new certificate shall entitle the holder thereof to all the rights, powers and privileges of a holder of such shares. d. Notwithstanding anything to the contrary contained in this Section B.8, the Corporation shall not be obligated to acquire any shares on any Redemption Date to the extent that the acquisition thereof would violate any law, statute, rule, regulation, policy or guideline promulgated by any federal, state, local or foreign governmental authority applicable to the Corporation, provided that the Corporation shall use all legally permissible methods in the reduction of capital and revaluation of assets, including appraisal, in order to obtain a legal 29. <PAGE> source of funds with which to pay the Redemption Payment and shall acquire such shares as soon as permitted by applicable laws, statutes, rules, regulations, policies and guidelines. 9. Miscellaneous. a. Shares of Series B Preferred Stock are not subject to or entitled to the benefit of a sinking fund. b. Redeemed shares of Series B Preferred Stock shall not be reissued but shall be retired. Upon the retirement of redeemed shares the capital of the Corporation shall be reduced. c.

Ranking. The Corporation's Series C Preferred Stock shall rank, as to dividends and upon redemption and Liquidation, (x) junior to the Series A, Series B and Series D Preferred Stock (but, with respect to Liquidation, only to the extent provided in Sections A.4, B.4, C.4, D.4 and E.4 hereof and with respect to redemption, only to the extent provided in Sections A.8, B.8, C.8 and D.8 hereof), (y) pari passu with the Series E Preferred Stock and (z) senior and prior to the Common Stock and to all other classes or series of stock issued by the Corporation. The Series C Preferred Stock shall have the following designations, powers, preferences, relative, participating, optional or other special rights, qualifications, limitations and restrictions: 3. Dividends. a. Dividends are payable on the Series C Preferred Stock, when, as and if declared by the Board of Directors. Whenever any dividend or other distribution is declared on any shares of Series C Preferred Stock, the Board of Directors shall simultaneously declare a dividend or distribution at the same percentage rate and in the same form on each other outstanding share of Series C and each outstanding share of Series E Preferred Stock, so that all outstanding shares of Series C and Series E Preferred Stock will participate equally with each other ratably per share. b. So long as any Series C Preferred Stock is outstanding the Corporation shall not declare or pay any dividend or make any distribution (whether in cash, shares of capital stock of the Corporation or other property) on shares of its Common Stock or any other class or series of stock ranking pari passu with or junior to the Series C Preferred Stock, unless prior thereto or simultaneously therewith all dividends and distributions previously 30. <PAGE> declared on the Series C Preferred Stock shall have been paid or the Corporation shall have irrevocably deposited or set aside cash or United States Obligations sufficient for the payment thereof. c. If the Board of Directors declares dividends or other distributions (other than (i) on Liquidation, (ii) on the Series A Preferred Stock pursuant to Section A.3(d) hereof, (iii) on the Series B Preferred Stock pursuant to Section B.3(d) hereof, or (iv) on the Series D Preferred Stock pursuant to Section D.3(d) hereof) on the Common Stock or any other class or series of stock ranking pari passu with or junior to the Series C Preferred Stock in cash, property or securities (excluding Common Stock) of the Corporation (or subscription or other rights to purchase or acquire securities (excluding Common Stock) of the Corporation), the Board of Directors shall simultaneously declare a dividend or distribution on the same terms, at the same or equivalent rate, and in the same form on each share of Series C Preferred Stock, so that all outstanding shares of Series C Preferred Stock will participate ratably with the Common Stock and each other class or series of stock ranking pari passu with or junior to the Series C Preferred Stock in such dividend or distribution. For purposes of determining its proportional share of the dividend or distribution, each share of the Series C Preferred Stock and any other applicable class or series of convertible securities shall be deemed to be that number of shares of Common Stock into which such share is then convertible, rounded to the nearest one-tenth of a share. 4. Rights on Liquidation, Dissolution, Winding-Up. a. With respect to rights on Liquidation, the Series C Preferred Stock shall rank (x) junior to the Series A, Series B and Series D Preferred Stock (but only to the extent provided in this Section C.4), (y) pari passu with the Series E Preferred Stock and (z) senior and prior to the Common Stock and to all other classes or series of stock issued by the Corporation. b. Subject to the holders of Series A Preferred Stock set forth in Section A.4 hereof, the holders of Series B Preferred Stock set forth in Section B.4 hereof and the holders of Series D Preferred Stock set forth in Section D.4 hereof, in the event of any Liquidation, whether voluntary or involuntary, before any payment of cash or distribution of other property shall be made to the Common Stockholders or any other class or series of stock ranking on Liquidation junior to the Series C Preferred Stock, the holders of Series C Preferred Stock shall be entitled to receive out of the assets of the Corporation legally available for distribution to its stockholders, pari passu with the rights of the Series E Stockholders, an amount per share equal to the Series C Preferred Liquidation Preference divided by the number of outstanding shares of Series C Preferred Stock whether from capital, surplus or earnings, plus an amount equal to any accrued but unpaid cumulative dividends thereon and any declared but unpaid dividends thereon. c. If, upon any Liquidation, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the Series C Preferred Stockholders the full amounts to which each of them shall be entitled pursuant to Section C.4(b) hereof and to pay the Series E Preferred Stockholders the full amount to which each of them shall be entitled pursuant to Section E.4(b) hereof, then the Series C and Series E Preferred Stockholders shall share ratably in any distribution of assets according to the respective amounts which would be 31. <PAGE> payable to them in respect of the shares of Series C or Series E Preferred Stock, as the case may be, held upon such distribution if all amounts payable on or with respect to such shares were paid in full pursuant to Sections C.4(b) and E.4(b) hereof. d. In the event of any Liquidation, the Series C Preferred Stock shall not be entitled to receive any payment of cash or distribution of property other than as expressly provided in this Section C.4. 5. Merger, Consolidation, etc. a. In the event the Corporation intends to sell, lease or otherwise dispose of all or substantially all of the assets of the Corporation, effect any transaction or series of related transactions in which more than 50% of the voting power of the Corporation is transferred (other than in connection with a Public Offering), or merge or consolidate with or into any other corporation, corporations or other entity or entities (other than a merger or consolidation in which the Series Preferred Stockholders receive securities of the surviving corporation having substantially similar rights to the Series Preferred Stock and in which the stockholders of the Corporation immediately prior to such a transaction are holders of at least a majority of the voting securities of the surviving corporation immediately thereafter), then the Corporation shall give written notice to each Series Preferred Stockholder no less than 20 days prior to the closing of any such transaction notifying the Series Preferred Stockholders of the terms and timing of the closing of such transaction and of the rights of the Series Preferred Stockholders under Sections A.5(b), B.5(b), C.5(b), D.5(b) and E.5(b) hereof. b. Upon the affirmative vote of the holders of not less than 75% in voting power of all of the shares of Series Preferred Stock then outstanding, voting together as a separate class, made prior to the consummation of such transaction, the proceeds of or any property deliverable from such transaction shall be distributed among the holders of the Series Preferred Stock and the Common Stock according to the provisions of Sections A.4, B.4, C.4, D.4 and E.4 hereof as if such transaction were a Liquidation. c. The voting rights of the holders of Series Preferred Stock contained in Sections A.5(b), B.5(b), C.5(b), D.5(b) and E.5(b) hereof may be exercised at a special meeting of the holders of Series Preferred Stockholders called as provided in accordance with the By-laws of the Corporation or by written consent of the holders of Series Preferred Stock in lieu of a meeting. 6. Voting. a. General. In addition to the rights otherwise provided for herein or by law, the Series C Preferred Stockholders shall be entitled to vote, together with the Series A Preferred Stockholders, the Series B Preferred Stockholders, the Series D Preferred Stockholders, the Series E Preferred Stockholders and the Common Stockholders and any other class or series of stock then entitled to vote, as one class on all matters as to which Common Stockholders shall be entitled to vote, in the same manner and with the same effect as the Common Stockholders, except as otherwise required by the General Corporation Law. In any such vote, and in any vote or action of the Series C Preferred Stockholders voting together as a 32. <PAGE> separate class or with the other holders of Series Preferred Stock as a separate class, each share of issued and outstanding Series C Preferred Stock shall entitle the holder thereof to one vote per share for each share of Common Stock (including fractional shares) into which each share of Series C Preferred Stock is then convertible, rounded to the nearest one-tenth of a share. b. Election of Board of Directors. (i) In addition to the rights specified in Sections A.6(a), B.6(a), C.6(a) and D.6(a) hereof, the holders of a majority in voting power of the Series A, Series B, Series C and Series D Preferred Stock, voting together as a separate class or in such other manner as the holders of the Series A, Series B, Series C and Series D Preferred Stock shall agree among themselves in the Stockholders' Agreement, shall have the exclusive right to elect to the Board of Directors of the Corporation that number of directors which shall be equal to a majority of the total number of directors on the Board of Directors at any given time. In any election of Preferred Directors pursuant to this Section C.6(b) and Sections A.6(b), B.6(b) and D.6(b), each share of issued and outstanding Series A, Series B, Series C and Series D Preferred Stock shall entitle the holder thereof to the number of votes per share that equals the number of shares of Common Stock (including fractional shares) into which each such share is then convertible, rounded up to the nearest one-tenth of a share. The voting rights of the Series A, Series B, Series C and Series D Preferred Stockholders contained in this Section C.6(b) and Sections A.6(b), B.6(b) and D.6(b) may be exercised at a special meeting of the Series Preferred Stockholders called as provided in accordance with the By-laws of the Corporation, at any annual or special meeting of the Stockholders of the Corporation, or by written consent of the holders of Series Preferred Stock in lieu of a meeting. The Preferred Directors elected pursuant to this Section C.6(b) and Sections A.6(b), B.6(b) and D.6(b) shall serve from the date of their election and qualification until their successors have been duly elected and qualified. (ii) Notwithstanding anything to the contrary contained in Sections A.6(b)(i), B.6(b)(i), C.6(b)(i) and D.6(b)(i) hereof, if an Event of Noncompliance is declared in accordance with the Stockholders' Agreement, the Series A, Series B, Series C and Series D Preferred Stockholders, voting together as a separate class, shall have the right to elect all of the members of the Board of Directors of the Corporation.

Protective Provisions. So long as any Series Preferred Stock is outstanding, the Corporation shall not, without the written consent in lieu of a meeting, or the affirmative vote at a meeting called for such purpose, of the holders of shares representing at least 75% of the combined voting power of the issued and outstanding Series A, Series B, Series C, Series D and Series E Preferred Stock, voting together as a single class: 33. <PAGE> (i) except for "Excluded Stock", authorize, issue or agree to authorize or issue any shares of capital stock of the Corporation, any right, warrant, or option to receive any capital stock, or any security convertible into or exchangeable for capital stock or any capitalized lease with any equity feature with respect to the capital stock of the Corporation; (ii) change as a whole, by subdivision or combination in any manner, the number of shares of the Common Stock then outstanding into a different number of shares, with or without par value, without making the identical change as a whole in the number of shares of Series Preferred Stock then outstanding; (iii) amend, alter or repeal, in any manner whatsoever, the designations, powers, preferences, relative, participating, optional or other special rights, qualifications, limitations and restrictions of the Series Preferred Stock; (iv) sell, abandon, transfer, lease or otherwise dispose of all or substantially all of the properties or assets of the Corporation or any of its subsidiaries; (v) declare or pay any dividend (other than as required by Section A.3(d) hereof in respect of the Series A Preferred Stock, by Section B.3(d) hereof in respect of the Series B Preferred Stock and by Section D.3(d) hereof in respect of the Series D Preferred Stock) or make any distribution (whether in cash, shares of capital stock of the Corporation, or other property) on shares of its capital stock other than the Series Preferred Stock; (vi) merge or consolidate with or into, or permit any subsidiary of the Corporation to merge or consolidate with or into, any other corporation, corporations or other entity or entities, or effect any transaction or series of related transactions in which more than 50% of the voting power of the Corporation is transferred (other than in connection with a Public Offering); (vii) voluntarily dissolve, liquidate or wind-up or carry out any partial Liquidation or distribution or transaction in the nature of a partial Liquidation or distribution; (viii) increase the number of shares of any series of Preferred Stock of the Corporation authorized to be issued; (ix) reclassify any shares of the Corporation's capital stock as shares ranking senior to or on parity with the Series Preferred Stock with respect to rights on Liquidation, redemption or for the payment of any dividend or distribution other than in Liquidation; (x) amend, alter or repeal any provision of the Certificate of Incorporation of the Corporation; (xi) amend, alter or repeal any provisions of the By-laws of the Corporation so as to adversely affect the rights of the holders of the Series Preferred Stock; or 34. <PAGE> (xii) directly or indirectly, redeem, purchase or otherwise acquire for value (including through an exchange), or set apart money or other property for any mandatory purchase or other analogous fund for the redemption, purchase or acquisition of, any shares of Common Stock, except (a) pursuant to Sections A.8, B.8, C.8 and D.8 hereof, and (b) pursuant to any agreement approved by the Board of Directors with an officer, director, employee or consultant providing for the repurchase of any capital stock of the Corporation owned by such officer, director, employee or consultant at the option of the Corporation, which is either (A) set forth on Schedule 4.10 of the Series B Stock Purchase Agreement, or (B) issued pursuant to the Option Plan, as amended prior to May 13, 1996, the 1997 Equity Incentive Plan, or any other stock option plan of the Corporation or one or more amendments to the Option Plan, from and after May 13, 1996, approved by the Board of Directors and by the holders of 75% of the then issued and outstanding Series Preferred Stock, voting together as a separate class. In any vote or written consent in lieu of a meeting pursuant to this Section C.6(c) and Sections A.6(c), B.6(c), D.6(c) and E.6(c) hereof, each share of issued and outstanding Series Preferred Stock shall entitle the holder thereof to the number of votes per share that equals the number of shares of Common Stock (including fractional shares) into which each such share is then convertible, rounded to the nearest one-tenth of a share. 7. Conversion. a. Right to Convert. (i) Any Series C Preferred Stockholder shall have the right, at any time or from time to time, prior to the Closing Date to convert any or all of its shares of Series C Preferred Stock into that number of fully paid and nonassessable shares of Common Stock for each share of Series C Preferred Stock so converted equal to the quotient of the Series C Preferred Original Purchase Price divided by the Series C Preferred Conversion Price (as last adjusted and then in effect) rounded to the nearest one-tenth of a share. (ii) (a) Any Series C Preferred Stock that remains unconverted on the Closing Date shall be automatically converted without notice and without any action on the part of the holder thereof into shares of Common Stock on the Closing Date in accordance with the preceding sentence. After the Closing Date all rights of holders of shares of Series C Preferred Stock with respect to Series C Preferred Stock, except the right to receive shares of Common Stock in accordance with this Section C.7(a)(ii)(a) and any accrued but unpaid dividends and any declared but unpaid dividends as in accordance with Section C.7(a)(ii)(c) hereof, shall cease and the shares of Series C Preferred Stock shall no longer be deemed to be outstanding, whether or not the Corporation has received the certificates representing such shares. (b) The Corporation shall promptly send by first-class mail, postage prepaid, to each Series C Preferred Stockholder at such holder's address appearing on the Corporation's records a copy of (i) each registration statement filed by the Corporation under the Securities Act and each amendment thereof and each exhibit and schedule thereto and (ii) each order of the Securities and Exchange Commission declaring any such registration statement to be effective. 35. <PAGE> (c) Holders of Series C Preferred Stock converted into shares of Common Stock pursuant to this Section C.7 shall be entitled to payment of any accrued but unpaid cumulative dividend and any declared but unpaid dividends payable with respect to such shares of Series C Preferred Stock, up to and including the Conversion Date or the Closing Date, as the case may be. b. Mechanics of Conversion. (i) Any Series C Preferred Stockholder that exercises its right to convert its shares of Series C Preferred Stock into Common Stock shall deliver the Preferred Certificate, duly endorsed or assigned in blank to the Corporation, during regular business hours, at the office of the transfer agent of the Corporation, if any, at the principal place of business of the Corporation or at such other place as may be designated by the Corporation. (ii) Each Preferred Certificate shall be accompanied by written notice stating that such holder elects to convert such shares and stating the name or names (with address) in which the Common Certificate(s) are to be issued. Such conversion shall be deemed to have been effected on the date when the aforesaid delivery is made. (iii) As promptly as practicable thereafter, the Corporation shall issue and deliver to or upon the written order of such holder, at the place designated by such holder, the Common Certificate(s) for the number of full shares of Common Stock to which such holder is entitled and a cash payment for any fractional interest in a share of Common Stock, as provided in Section C.7(c) hereof, and for any accrued but unpaid cumulative dividends and any declared but unpaid dividends, payable with respect to the converted shares of Series C Preferred Stock, up to and including the Conversion Date or the Closing Date, as the case may be. (iv) The person in whose name each Common Certificate is to be issued shall be deemed to have become a stockholder of record of Common Stock on the Conversion Date or the Closing Date, as the case may be, unless the transfer books of the Corporation are closed on that date, in which event such holder shall be deemed to have become a stockholder of record on the next succeeding date on which the transfer books are open; provided, that the Series C Preferred Conversion Price shall be that in effect on the Conversion Date or the Closing Date, as the case may be. (v) Upon conversion of only a portion of the shares of Series C Preferred Stock covered by a Preferred Certificate, the Corporation, at its own expense, shall issue and deliver to or upon the written order of the holder of such Preferred Certificate, a new certificate representing the number of unconverted shares of Series C Preferred Stock from the Preferred Certificate so surrendered. c. Issuance of Common Stock on Conversion. (i) If a Series C Preferred Stockholder shall surrender more than one Preferred Certificate for conversion at any one time, the number of such shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Series C Preferred Stock so surrendered. 36. <PAGE> (ii) No fractional shares of Common Stock shall be issued upon conversion of shares of Series C Preferred Stock. The Corporation shall pay a cash adjustment for such fractional interest in an amount equal to the then Current Market Price of a share of Common Stock multiplied by such fractional interest. (d) Conversion Price; Adjustment. The "Series C Preferred Conversion Price" with respect to the Series C Preferred Stock shall initially be equal to the Series C Preferred Original Purchase Price and shall be subject to adjustment from time to time as follows: (i) If the Corporation shall at any time after the Series C Preferred Original Issuance Date fix a record date for the subdivision, split- up or stock dividend of shares of Common Stock, then, following the record date fixed for the determination of holders of Common Stock entitled to receive such subdivision, split-up or dividend (or the date of such subdivision, split-up or dividend, if no record date is fixed), the Series C Preferred Conversion Price shall be appropriately decreased so that the number of shares of Common Stock issuable on conversion of each share of the Series C Preferred Stock shall be increased in proportion to such increase in outstanding shares. (ii) If, at any time after the Series C Preferred Original Issuance Date, the number of shares of Common Stock outstanding is decreased by a combination of the outstanding shares of Common Stock, then, following the record date fixed for such combination (or the date of such combination, if no record date is fixed), the Series C Preferred Conversion Price shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of Series C Preferred Stock shall be decreased in proportion to such decrease in outstanding shares. (iii) If, at any time after the Series C Preferred Original Issuance Date, an Extraordinary Transaction is consummated, the Series C Preferred Conversion Price with respect to the Series C Preferred Stock outstanding after the Extraordinary Transaction shall be adjusted to provide that the shares of Series C Preferred Stock outstanding immediately prior to the effectiveness of the Extraordinary Transaction shall be convertible into the kind and number of shares of stock or other securities or property of the Corporation or of the corporation resulting from or surviving such Extraordinary Transaction which the holder of the number of shares of Common Stock deliverable (immediately prior to the effectiveness of the Extraordinary Transaction) upon conversion of such Series C Preferred Stock would have been entitled to receive upon such Extraordinary Transaction. The provisions of this Section C.7(d)(iii) shall similarly apply to successive Extraordinary Transactions. (iv) All calculations under this Section C.7(d) shall be made to the nearest one-tenth of a cent ($.001) or to the nearest one-tenth of a share, as the case may be. (v) In any case in which the provisions of this Section C.7(d) shall require that an adjustment shall become effective immediately after a record date for an event, the Corporation may defer until the occurrence of that event (A) issuing to the holder of any share of Series C Preferred Stock converted after such record date and before the occurrence of such event the additional shares of capital stock issuable upon such conversion by reason of 37. <PAGE> the adjustment required by such event over and above the shares of capital stock issuable upon such conversion before giving effect to such adjustment and (B) paying to such holder any amount in cash in lieu of a fractional share of capital stock pursuant to Section C.7(c) hereof; provided, however, that the Corporation shall deliver to such holder a due bill or other appropriate instrument evidencing such holder's right to receive such additional shares, in such case, upon the occurrence of the event requiring such adjustment. e. Notice of Adjustments. (i) Whenever the Series C Preferred Conversion Price shall be adjusted as provided in Section C.7(d) hereof, the Corporation shall file, at its principal office, at the office of the transfer agent for the Series C Preferred Stock, if any, or at such other place as may be designated by the Corporation, a statement, signed by its President and by its Chief Financial Officer, showing in detail the facts requiring such adjustment and the Series C Preferred Conversion Price that shall be in effect after such adjustment. The Corporation shall also cause a copy of such statement to be sent by first-class, certified mail, return receipt requested, postage prepaid, to each Series C Preferred Stockholder at such holder's address appearing on the Corporation's records. Where appropriate, such copy may be given in advance and may be included as part of a notice required to be mailed under the provisions of Section C.7(e)(ii) hereof. (ii) In the event the Corporation shall propose to file a registration statement under the Securities Act for a Public Offering or to take any action of the types described in clauses (i), (ii) or (iii) of Section C.7(d) hereof, the Corporation shall give notice to each Series C Preferred Stockholder, in the manner set forth in Section C.7(e)(i) hereof, which shall specify the record date, if any, with respect to any such action and the date on which such action is to take place. The notice shall also set forth such facts as are reasonably necessary to indicate the effect of such action (to the extent such effect may be known at the date of such notice) on the Series C Preferred Conversion Price and the number, kind or class of shares or other securities or property which shall be deliverable or purchasable upon the occurrence of such action or deliverable upon conversion of shares of Series C Preferred Stock. In the case of any action which would require the fixing of a record date, such notice shall be given at least ten (10) days prior to the date so fixed, and in case of all other action, such notice shall be given at least fifteen (15) days prior to the taking of such proposed action. Failure to give notice under this Section C.7(e)(ii), or any defect therein, shall not affect the legality or validity of any such action. f. Transfer Taxes. The Corporation shall pay all documentary, stamp or other transactional taxes (excluding income taxes) attributable to the issuance or delivery of shares of capital stock of the Corporation upon conversion of any shares of Series C Preferred Stock; provided, however, that the Corporation shall not be required to pay any taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificate for such shares in a name other than that of the holder of the shares of Series C Preferred Stock in respect of which such shares are being issued. g. Reservation of Common Stock. The Corporation shall at all times reserve, free from preemptive rights, out of its authorized but unissued shares of Common 38. <PAGE> Stock, solely for the purpose of effecting the conversion of the shares of Series C Preferred Stock, sufficient shares of Common Stock to provide for the conversion of all outstanding shares of Series C Preferred Stock. h. Status of Common Stock. All shares of Common Stock which may be issued in connection with the conversion provisions set forth herein will, upon issuance by the Corporation, be validly issued, fully paid and nonassessable, free from preemptive rights and free from all taxes, liens or charges with respect thereto created or imposed by the Corporation. 8. Redemption. a. On and after the Series B Preferred Fifth Anniversary Date or at any time if an Event of Noncompliance is declared in accordance with the Stockholders' Agreement, at the written request of the holders of shares representing not less than 75% of the combined voting power of the Series A, Series B, Series C and Series D Preferred Stock then outstanding, voting together as a single class, made, from time to time, at any date on or after the Series B Preferred Fifth Anniversary Date or upon the declaration of an Event of Noncompliance, the Corporation shall redeem (unless otherwise prevented by law) all of the shares of Series A, Series B and Series D Preferred Stock, at a redemption price per share for each such series of Series Preferred Stock equal to (i) the Series A Preferred Original Purchase Price, Series B Preferred Original Purchase Price or the Series D Preferred Original Purchase Price, as applicable, plus (ii) an amount equal to any accrued but unpaid cumulative dividends thereon and any declared but unpaid dividends thereof, and, then, all of the shares of Series C Preferred Stock, at a redemption price per share for such Series C Preferred Stock equal to (i) the Series C Preferred Original Purchase Price plus (ii) an amount equal to any accrued but unpaid dividends thereon and any declared but unpaid dividends thereon. For purposes of determining whether the requisite 75% of the holders of Series A, Series B, Series C and Series D Preferred Stock are participating in the Redemption Notice, each share of issued and outstanding Series A, Series B, Series C and Series D Preferred Stock shall entitle the holder thereof to one vote per share for each share of Common Stock (including fractional shares) into which each share of Series A, Series B, Series C and Series D Preferred Stock is then convertible, rounded to the nearest one-tenth of a share. b. On and after the Redemption Date, all rights of any Series C Preferred Stockholder with respect to the shares of Series C Preferred Stock redeemed on that Redemption Date, except the right to receive the Redemption Payment as provided herein, shall cease, and such shares shall no longer be deemed to be outstanding, whether or not the Corporation has received the certificates representing such shares, on the condition that the Corporation pays the Redemption Payment, or irrevocably deposits or sets aside cash in an amount equal to the Redemption Payment; provided, however, that if the Corporation defaults in the payment of the Redemption Payment, the rights of the holder with respect to such shares of Series C Preferred Stock shall continue until the Corporation cures such default. c. The Requesting Holders shall send their Redemption Notice pursuant to this Section C.8 by first-class, certified mail, return receipt requested, postage prepaid, to the Corporation at its principal place of business or to any transfer agent of the 39. <PAGE> Corporation. The Corporation shall fix a date for redemption which shall not be more than 60 days after the receipt of Redemption Notices from the Requesting Holders. Not less than 45 days prior to the Redemption Date, written notice shall be mailed, first class postage prepaid, to each holder of record (at the close of business on the business day next preceding the day on which notice is given) of the Series A, Series B, Series C and Series D Preferred Stock, at the address last shown on the records of the Corporation for such holder or given by the holder to the Corporation for the purpose of notice, notifying such holder of the redemption to be effected, the Redemption Date fixed, the Redemption Payment, the place at which payment may be obtained and the date on which such holder's conversion rights as to such shares terminate and calling upon such holder to surrender to the Corporation, in the manner and at the place designated, such holder's certificate or certificates representing the shares to be redeemed. In the event of only a partial redemption of the outstanding shares of the Series C Preferred Stock entitled to redemption for any reason, the redemption of the Series C Preferred Stock shall be pro rata based upon the total amount that would be paid by the Corporation to each Series C Preferred Stockholder if all of the shares of the Series C Preferred Stock were fully redeemed pursuant to Section C.8(a) hereof. At any time on or after the Redemption Date, the holders of the Series C Preferred Stock shall be entitled to receive the Redemption Payment for each of the shares of Series C Preferred Stock held by such holder which are to be redeemed by the Corporation upon actual delivery to the Corporation or its transfer agent of the certificate(s) representing the shares to be redeemed. Upon redemption of only a portion of the number of shares covered by a Series C Preferred Stock certificate, the Corporation shall issue and deliver to or upon the written order of the holder of such Series C Preferred Stock certificate, at the expense of the Corporation, a new certificate covering the number of shares of Series C Preferred Stock being redeemed representing the unredeemed portion of the Series C Preferred Stock certificate, which new certificate shall entitle the holder thereof to all the rights, powers and privileges of a holder of such shares. d. Notwithstanding anything to the contrary contained in this Section C.8, the Corporation shall not be obligated to acquire any shares on any Redemption Date to the extent that the acquisition thereof would violate any law, statute, rule, regulation, policy or guideline promulgated by any federal, state, local or foreign governmental authority applicable to the Corporation, provided that the Corporation shall use all legally permissible methods in the reduction of capital and revaluation of assets, including appraisal, in order to obtain a legal source of funds with which to pay the Redemption Payment and shall acquire such shares as soon as permitted by applicable laws, statutes, rules, regulations, policies and guidelines. 9. Miscellaneous. a. Shares of Series C Preferred Stock are not subject to or entitled to the benefit of a sinking fund. b.

The Corporation's Series D Preferred Stock shall rank, as to dividends and upon redemption and Liquidation, (x) pari passu with the Series A and Series B Preferred Stock, (y) senior and prior to the Series C Preferred Stock and Series E Preferred Stock (but, with respect to Liquidation, only to the extent provided in Section D.4 hereof and with respect to redemption, only to the extent provided in Section D.8 hereof), and (z) senior and prior to the Common Stock and to all other classes or series of stock issued by the Corporation, except in the case of a change in the relative ranking of the Series A Preferred Stock, the Series B Preferred Stock and the Series D Preferred Stock, as otherwise approved by the affirmative vote or consent of the holders of 75% of the issued and outstanding shares of Series A, Series B and Series D Preferred Stock voting together. The Series D Preferred Stock shall have the following designations, powers, preferences, relative, participating, optional or other special rights, qualifications, limitations and restrictions: 3. Dividends. a. Dividends are payable on the Series D Preferred Stock, when, as and if declared by the Board of Directors. Whenever any dividend or other distribution is declared on any shares of Series D Preferred Stock, the Board of Directors shall simultaneously declare a dividend or distribution at the same percentage rate and in the same form on each other outstanding share of Series D Preferred Stock and each outstanding share of Series A and Series B Preferred Stock, so that all outstanding shares of Series A, Series B and Series D Preferred Stock will participate equally with each other ratably per share. b. So long as any Series D Preferred Stock is outstanding the Corporation shall not declare or pay any dividend or make any distribution (whether in cash, shares of capital stock of the Corporation or other property) on shares of its Common Stock or any other class or series of stock ranking pari passu with or junior to the Series D Preferred Stock, unless prior thereto or simultaneously therewith (A) all dividends and distributions previously declared on the Series D Preferred Stock and (B) any cumulative dividends in accordance with Section D.3(d) hereof shall have been paid or the Corporation shall have irrevocably deposited or set aside cash or United States Obligations sufficient for the payment thereof. c. If the Board of Directors declares dividends or other distributions (other than on Liquidation) on the Common Stock or any other class or series of stock ranking pari passu with or junior to the Series D Preferred Stock in cash, property or securities 41. <PAGE> excluding Common Stock) of the Corporation (or subscription or other rights to purchase or acquire securities (excluding Common Stock) of the Corporation), the Board of Directors shall simultaneously declare a dividend or distribution on the same terms, at the same or equivalent rate, and in the same form on each share of Series D Preferred Stock, so that all outstanding shares of Series D Preferred Stock will participate ratably with the shares of Common Stock and the shares of each other class or series of stock ranking pari passu with or junior to the Series D Preferred Stock in such dividend or distribution. For purposes of determining its proportional share of the dividend or distribution, each share of the Series D Preferred Stock and any other applicable class or series of convertible securities shall be deemed to be that number of shares of Common Stock into which such share is then convertible, rounded to the nearest one- tenth of a share. d. From and after the Series A Preferred Fifth Anniversary Date and until the date of the consummation of the Corporation's first Public Offering, the Series D Preferred Stock will be entitled, pari passu with the Series A and Series B Preferred Stock, to dividends, to be paid quarterly, in cash or in kind at the discretion of the Board of Directors, at an annual rate of five percent (5%) of the Series D Preferred Original Purchase Price (or such greater amount of dividends as such Series D Preferred Stock would be entitled to if such Series D Preferred Stock were converted into Common Stock), as adjusted for any combinations or divisions or similar recapitalizations affecting the Series D Preferred Stock after the Series D Preferred Original Issuance Date, payable on the first day of January, April, July and October (and any dividends payable to holders of Series D Preferred Stock which are not paid shall be cumulative). Upon conversion of any Series D Preferred Stock, all accrued but unpaid cumulative dividends and any declared but unpaid dividends shall be paid in cash, or in additional shares of Common Stock at the Series D Preferred Conversion Price then in effect in the discretion of the Board of Directors. Nothing in this Section D.3(d) shall be deemed to limit the rights of the Series D Preferred Stock under Sections D.3(b) and D.3(c) hereof. 4. Rights on Liquidation, Dissolution, Winding-Up. a. With respect to rights on Liquidation, the Series D Preferred Stock shall rank (x) pari passu with the Series A and Series B Preferred Stock, (y) senior and prior to the Series C Preferred Stock and Series E Preferred Stock (but only to the extent provided in this Section D.4) and (z) senior and prior to the Common Stock and to all other classes or series of stock issued by the Corporation, except in the case of a change in the relative ranking upon Liquidation of the Series A, Series B and Series D Preferred Stock, as otherwise approved by the affirmative vote or consent of the holders of 75% of the issued and outstanding shares of Series A, Series B and Series D Preferred Stock voting together. b. In the event of any Liquidation, whether voluntary or involuntary, before any payment of cash or distribution of other property shall be made to the Series C Preferred Stockholders, Series E Preferred Stockholders or the Common Stockholders or any other class or series of stock ranking on Liquidation junior to the Series D Preferred Stock, the holders of Series D Preferred Stock shall be entitled to receive out of the assets of the Corporation legally available for distribution to its stockholders, pari passu with the rights of the Series A and Series B Preferred Stockholders, an amount per share equal to the Series D Preferred Original Purchase Price whether from capital, surplus or earnings, plus an amount 42. <PAGE> equal to any accrued but unpaid cumulative dividends thereon and any declared but unpaid dividends thereon. c. If, upon any Liquidation, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the Series D Preferred Stockholders the full amounts to which each of them shall be entitled pursuant to Section D.4(b) hereof and to pay to the Series A and Series B Preferred Stockholders the full amount to which each of them shall be entitled pursuant to Sections A.4(b) and B.4(b) hereof, then the Series A, Series B and Series D Preferred Stockholders shall share ratably in any distribution of assets according to the respective amounts which would be payable to them in respect of the shares of Series A, Series B or Series D Preferred Stock, as the case may be, held upon such distribution if all amounts payable on or with respect to such shares were paid in full pursuant to Sections A.4(b), B.4(b) and D.4(b) hereof. d. In the event of any Liquidation, after payment shall have been made to (i) the Series A, Series B and Series D Preferred Stockholders of the full amount to which they shall be entitled pursuant to Sections A.4(b), B.4(b) and D.4(b) hereof, respectively, and (ii) the Series C and Series E Preferred Stockholders of the full amount to which they shall be entitled pursuant to Section C.4(b) and E.4(b) hereof, respectively, with respect to each other class or series of capital stock (other than the Series C Preferred Stock, Series E Preferred Stock and the Common Stock) ranking on Liquidation junior to such Series D Preferred Stock (in descending order of seniority), the Series A, Series B and Series D Preferred Stockholders, as a class, shall be entitled to receive an amount equal (and in like kind) to the aggregate preferential amount fixed for each such junior class or series of capital stock, which amount shall be distributed ratably among the Series A Preferred Stockholders in an equal amount per share of the Series A Preferred Stock then outstanding and among the Series B Preferred Stockholders in an equal amount per share of the Series B Preferred Stock then outstanding and among the Series D Preferred Stockholders in an equal amount per share of the Series D Preferred Stock then outstanding. If, upon any Liquidation, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the Series A Preferred Stockholders, the Series B Preferred Stockholders, the Series D Preferred Stockholders and each class or series of capital stock (other than the Series C Preferred Stock, and Series E Preferred Stock and the Common Stock) junior to the Series D Preferred Stock the full amounts to which they shall be entitled pursuant to the immediately preceding sentence, the Series A, Series B and Series D Preferred Stockholders shall be entitled to share ratably with each such other class or series of capital stock in any distribution of assets according to the respective preferential amounts fixed for the Series A Preferred Stock (pursuant to Section A.4(b) hereof), the Series B Preferred Stock (pursuant to Section B.4(b) hereof) and the Series D Preferred Stock (pursuant to Section D.4(b) hereof), and each such junior class or series of capital stock (pursuant to the applicable terms thereof), which would be payable in respect of the shares held by them upon such distribution if all such preferential amounts payable on or with respect to such shares were paid in full. e. In the event of any Liquidation, after payment shall have been made to the Series A Preferred Stockholders, the Series B Preferred Stockholders, the Series C Preferred Stockholders, Series D Preferred Stockholders and the Series E Preferred Stockholders of the full amount to which they shall be entitled as aforesaid, and after payment shall have made of the respective preferential amounts of all other classes and series of capital stock ranking 43. <PAGE> senior to the Common Stock, the Series A, Series B and Series D Preferred Stockholders shall be entitled to share ratably (calculated with respect to such Series A, Series B and Series D Preferred Stock as provided in the next sentence) with the holders of Common Stock in all remaining assets of the Corporation available for distribution to its stockholders. For purposes of calculating the amount of any payment to be paid pursuant to this Section D.4(e) upon any such Liquidation, each share of Series A, Series B and Series D Preferred Stock shall be deemed to be that number of shares of Common Stock into which such share is then convertible, rounded to the nearest one-tenth of a share. 5. Merger, Consolidation, etc. a. In the event the Corporation intends to sell, lease or otherwise dispose of all or substantially all of the assets of the Corporation, effect any transaction or series of related transactions in which more than 50% of the voting power of the Corporation is transferred (other than in connection with a Public Offering), or merge or consolidate with or into any other corporation, corporations or other entity or entities (other than a merger or consolidation in which the Series Preferred Stockholders receive securities of the surviving corporation having substantially similar rights to the Series Preferred Stock and in which the stockholders of the Corporation immediately prior to such a transaction are holders of at least a majority of the voting securities of the surviving corporation immediately thereafter), then the Corporation shall give written notice to each Series Preferred Stockholder no less than 20 days prior to the closing of any such transaction notifying the Series Preferred Stockholders of the terms and timing of the closing of such transaction and of the rights of the Series Preferred Stockholders under Sections A.5(b), B.5(b), C.5(b), D.5(b) and E.5(b) hereof. b. Upon the affirmative vote of the holders of not less than 75% in voting power of all of the shares of Series Preferred Stock then outstanding, voting together as a separate class, made prior to the consummation of such transaction, the proceeds of or any property deliverable from such transaction shall be distributed among the holders of the Series Preferred Stock and the Common Stock according to the provisions of Sections A.4, B.4, C.4, D.4 and E.4 hereof as if such transaction were a Liquidation. c. The voting rights of the holders of Series Preferred Stock contained in Sections A.5(b), B.5(b), C.5(b), D.5(b) and E.5(b) hereof may be exercised at a special meeting of the holders of Series Preferred Stockholders called as provided in accordance with the By-laws of the Corporation or by written consent of the holders of Series Preferred Stock in lieu of a meeting. 6. Voting. a. General. In addition to the rights otherwise provided for herein or by law, the Series D Preferred Stockholders shall be entitled to vote, together with the Series A Preferred Stockholders, the Series B Preferred Stockholders, the Series C Preferred Stockholders, the Series E Preferred Stockholders and the Common Stockholders and any other class or series of stock then entitled to vote, as one class on all matters as to which Common Stockholders shall be entitled to vote, in the same manner and with the same effect as the Common Stockholders, except as otherwise required by the General Corporation Law. In any such vote, and in any vote 44. <PAGE> or action of the Series D Preferred Stockholders voting together as a separate class or with the other holders of Series Preferred Stock as a separate class, each share of issued and outstanding Series D Preferred Stock shall entitle the holder thereof to one vote per share for each share of Common Stock (including fractional shares) into which each share of Series D Preferred Stock is then convertible, rounded to the nearest one-tenth of a share. b. Election of Board of Directors. (i) In addition to the rights specified in Sections A.6(a), B.6(a), C.6(a) and D.6(a) hereof, the holders of a majority in voting power of the Series A, Series B, Series C and Series D Preferred Stock, voting together as a separate class or in such other manner as the holders of the Series A, Series B, Series C and Series D Preferred Stock shall agree among themselves in the Stockholders' Agreement, shall have the exclusive right to elect to the Board of Directors of the Corporation that number of directors which shall be equal to a majority of the total number of directors on the Board of Directors at any given time. In any election of Preferred Directors pursuant to this Section D.6(b) and Sections A.6(b), B.6(b) and C.6(b), each share of issued and outstanding Series A, Series B, Series C and Series D Preferred Stock shall entitle the holder thereof to the number of votes per share that equals the number of shares of Common Stock (including fractional shares) into which each such share is then convertible, rounded up to the nearest one-tenth of a share. The voting rights of the Series A, Series B, Series C and Series D Preferred Stockholders contained in this Section D.6(b) and Sections A.6(b), B.6(b) and C.6(b) may be exercised at a special meeting of the Series Preferred Stockholders called as provided in accordance with the By-laws of the Corporation, at any annual or special meeting of the Stockholders of the Corporation, or by written consent of the holders of Series Preferred Stock in lieu of a meeting. The Preferred Directors elected pursuant to this Section D.6(b) and Sections A.6(b), B.6(b) and C.6(b) shall serve from the date of their election and qualification until their successors have been duly elected and qualified. (ii) Notwithstanding anything to the contrary contained in Sections A.6(b)(i), B.6(b)(i), C.6(b)(i) and D.6(b)(i) hereof, if an Event of Noncompliance is declared in accordance with the Stockholders' Agreement, the Series A, Series B, Series C and Series D Preferred Stockholders, voting together as a separate class, shall have the right to elect all of the members of the Board of Directors of the Corporation.

Conversion. a. Right to Convert. (i) Any Series D Preferred Stockholder shall have the right, at any time or from time to time, prior to the Closing Date to convert any or all of its shares of Series D Preferred Stock into that number of fully paid and nonassessable shares of Common Stock for each share of Series D Preferred Stock so converted equal to the quotient of the Series D Preferred Original Purchase Price divided by the Series D Preferred Conversion Price (as last adjusted and then in effect) rounded to the nearest one-tenth of a share. (ii) (a) Any Series D Preferred Stock that remains unconverted on the Closing Date shall be automatically converted without notice and without any action on the part of the holder thereof into shares of Common Stock on the Closing Date in accordance with the preceding sentence. After the Closing Date all rights of holders of shares of Series D Preferred Stock with respect to Series D Preferred Stock, except the right to receive shares of Common Stock in accordance with this Section D.7(a)(ii)(a) and any accrued but unpaid dividends and any declared but unpaid dividends as in accordance with Section D.7(a)(ii)(c) hereof, shall cease and the shares of Series D Preferred Stock shall no longer be deemed to be outstanding, whether or not the Corporation has received the certificates representing such shares. (b) The Corporation shall promptly send by first- class mail, postage prepaid, to each Series D Preferred Stockholder at such holder's address appearing on the Corporation's records a copy of (i) each registration statement filed by the Corporation under the Securities Act and each amendment thereof and each exhibit and schedule thereto and (ii) each order of the Securities and Exchange Commission declaring any such registration statement to be effective. 47. <PAGE> (c) Holders of Series D Preferred Stock converted into shares of Common Stock pursuant to this Section D.7 shall be entitled to payment of any accrued but unpaid cumulative dividend and any declared but unpaid dividends payable with respect to such shares of Series D Preferred Stock, up to and including the Conversion Date or the Closing Date, as the case may be. b. Mechanics of Conversion. (i) Any Series D Preferred Stockholder that exercises its right to convert its shares of Series D Preferred Stock into Common Stock shall deliver the Preferred Certificate, duly endorsed or assigned in blank to the Corporation, during regular business hours, at the office of the transfer agent of the Corporation, if any, at the principal place of business of the Corporation or at such other place as may be designated by the Corporation. (ii) Each Preferred Certificate shall be accompanied by written notice stating that such holder elects to convert such shares and stating the name or names (with address) in which the Common Certificate(s) are to be issued. Such conversion shall be deemed to have been effected on the date when the aforesaid delivery is made. (iii) As promptly as practicable thereafter, the Corporation shall issue and deliver to or upon the written order of such holder, at the place designated by such holder, the Common Certificate(s) for the number of full shares of Common Stock to which such holder is entitled and a cash payment for any fractional interest in a share of Common Stock, as provided in Section D.7(c) hereof, and for any accrued but unpaid cumulative dividends and any declared but unpaid dividends, payable with respect to the converted shares of Series D Preferred Stock, up to and including the Conversion Date or the Closing Date, as the case may be. (iv) The person in whose name each Common Certificate is to be issued shall be deemed to have become a stockholder of record of Common Stock on the Conversion Date or the Closing Date, as the case may be, unless the transfer books of the Corporation are closed on that date, in which event such holder shall be deemed to have become a stockholder of record on the next succeeding date on which the transfer books are open; provided, that the Series D Preferred Conversion Price shall be that in effect on the Conversion Date or the Closing Date, as the case may be. (v) Upon conversion of only a portion of the shares of Series D Preferred Stock covered by a Preferred Certificate, the Corporation, at its own expense, shall issue and deliver to or upon the written order of the holder of such Preferred Certificate, a new certificate representing the number of unconverted shares of Series D Preferred Stock from the Preferred Certificate so surrendered. c. Issuance of Common Stock on Conversion. (i) If a Series D Preferred Stockholder shall surrender more than one Preferred Certificate for conversion at any one time, the number of such shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Series D Preferred Stock so surrendered. 48. <PAGE> (ii) No fractional shares of Common Stock shall be issued upon conversion of shares of Series D Preferred Stock. The Corporation shall pay a cash adjustment for such fractional interest in an amount equal to the then Current Market Price of a share of Common Stock multiplied by such fractional interest. d. Conversion Price; Adjustment. The "Series D Preferred Conversion Price" with respect to the Series D Preferred Stock shall initially be equal to the Series D Preferred Original Purchase Price and shall be subject to adjustment from time to time as follows: (i) If the Corporation shall, at any time or from time to time after the Series D Preferred Original Issuance Date, make a Dilutive Issuance, the Series D Preferred Conversion Price in effect immediately prior to each such Dilutive Issuance shall automatically be lowered to a price (calculated to the nearest cent) determined by multiplying the Series D Preferred Conversion Price by a fraction, (A) the numerator of which shall be (1) the number of shares of Common Stock outstanding immediately prior to such issuance plus (2) the number of shares of Common Stock which the aggregate consideration received or to be received by the Corporation in such Dilutive Issuance so issued would purchase at the Series D Preferred Conversion Price; and (B) the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance plus the number of such additional shares of Common Stock so issued in such Dilutive Issuance; provided that, for the purpose of this Section D.7(d)(i), all shares of Common Stock issuable upon exercise or conversion of options or convertible securities outstanding immediately prior to such issuance (other than any additional shares of Common Stock issuable with respect to shares of Series Preferred Stock, convertible securities, or outstanding options, warrants or other rights for the purchase of shares of Common Stock or convertible securities, solely as a result of either (x) the Dilutive Issuance or (y) the adjustment of the Series D Preferred Conversion Price (or other conversion ratios applicable to other Series Preferred Stock and otherwise) resulting from the Dilutive Issuance) shall be deemed to be outstanding. For the purposes of any adjustment of the Series D Preferred Conversion Price pursuant to this Section D.7(d)(i), the following provisions shall be applicable: (a) In the case of the issuance of Common Stock in whole or in part for cash, the consideration shall be deemed to be the amount of cash paid therefor, plus the value of any property other than cash received by the Corporation as provided in Section D.7(d)(i)(b) hereof, less any discounts, commissions or other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with the issuance and sale thereof. (b) In the case of the issuance of Common Stock for consideration in whole or in part in property or consideration other than cash, the value of such property or consideration other than cash shall be deemed to be the fair market value thereof as determined in good faith by the Board of Directors of the Corporation, irrespective of any accounting treatment; provided, however, that such fair market value shall not exceed the aggregate Current Market Price of the shares of Common Stock being issued, less any cash consideration paid for such shares. 49. <PAGE> (c) In the case of the issuance of (I) options to purchase or rights to subscribe for Common Stock, (II) securities convertible into or exchangeable for Common Stock or (III) options to purchase or rights to subscribe for such convertible or exchangeable securities: (1) the aggregate maximum number of shares of Common Stock deliverable upon exercise of such options to purchase, or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in Sections D.7(d)(i)(a) and (b) hereof, if any, received by the Corporation upon the issuance of such options or rights plus the minimum purchase price provided in such options or rights for the Common Stock covered thereby; (2) the aggregate maximum number of shares of Common Stock deliverable upon conversion of, or in exchange for, any such convertible or exchangeable securities or upon the exercise of options to purchase, or rights to subscribe for, such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration received by the Corporation for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the additional consideration, if any, to be received by the Corporation upon the conversion or exchange of such securities or the exercise of any related options or rights (determined in the manner provided in Sections D.7(d)(i)(a) and (b) hereof); (3) if there is any decrease in the conversion or exercise price of, or any increase in the number of shares to be received upon exercise, conversion or exchange of any such options, rights or convertible or exchangeable securities (other than a change resulting from the antidilution provisions thereof), the Series D Preferred Conversion Price shall be automatically lowered to reflect such change; and (4) on the expiration of any right or option referred to in Sections D.7(d)(i)(c)(1) or (2) hereof or on the termination of any right to convert or exchange any convertible or exchangeable securities referred to in Section D.7(d)(i)(c)(2) hereof, the Series D Preferred Conversion Price then in effect shall thereupon be readjusted to the Series D Preferred Conversion Price as would have been in effect had the adjustment made upon the granting or issuance of such rights or options or convertible or exchangeable securities been made upon the basis of the issuance or sale of only the number of shares of Common Stock actually issued upon the exercise of such options or rights or upon the conversion or exchange of such convertible or exchangeable securities. (ii) If the Corporation shall at any time after the Series D Preferred Original Issuance Date fix a record date for the subdivision, split-up or stock dividend of shares of Common Stock, then, following the record date fixed for the determination of holders of Common Stock entitled to receive such subdivision, split-up or dividend (or the date of such subdivision, split-up or dividend, if no record date is fixed), the Series D Preferred Conversion Price shall be appropriately decreased so that the number of shares of Common 50. <PAGE> Stock issuable on conversion of each share of the Series A Preferred Stock shall be increased in proportion to such increase in outstanding shares. (iii) If, at any time after the Series D Preferred Original Issuance Date, the number of shares of Common Stock outstanding is decreased by a combination of the outstanding shares of Common Stock, then, following the record date fixed for such combination (or the date of such combination, if no record date is fixed), the Series D Preferred Conversion Price shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of Series D Preferred Stock shall be decreased in proportion to such decrease in outstanding shares. (iv) If, at any time after the Series D Preferred Original Issuance Date, an Extraordinary Transaction is consummated, the Series D Preferred Conversion Price with respect to the Series D Preferred Stock outstanding after the Extraordinary Transaction shall be adjusted to provide that the shares of Series D Preferred Stock outstanding immediately prior to the effectiveness of the Extraordinary Transaction shall be convertible into the kind and number of shares of stock or other securities or property of the Corporation or of the corporation resulting from or surviving such Extraordinary Transaction which the holder of the number of shares of Common Stock deliverable (immediately prior to the effectiveness of the Extraordinary Transaction) upon conversion of such Series D Preferred Stock would have been entitled to receive upon such Extraordinary Transaction. The provisions of this Section D.7(d)(iv) shall similarly apply to successive Extraordinary Transactions. (v) All calculations under this Section D.7(d) shall be made to the nearest one-tenth of a cent ($.001) or to the nearest one-tenth of a share, as the case may be. (vi) In any case in which the provisions of this Section D.7(d) shall require that an adjustment shall become effective immediately after a record date for an event, the Corporation may defer until the occurrence of that event (A) issuing to the holder of any share of Series D Preferred Stock converted after such record date and before the occurrence of such event the additional shares of capital stock issuable upon such conversion by reason of the adjustment required by such event over and above the shares of capital stock issuable upon such conversion before giving effect to such adjustment and (B) paying to such holder any amount in cash in lieu of a fractional share of capital stock pursuant to Section D.7(c) hereof; provided, however, that the Corporation shall deliver to such holder a due bill or other appropriate instrument evidencing such holder's right to receive such additional shares, in such case, upon the occurrence of the event requiring such adjustment. e. Notice of Adjustments. (i) Whenever the Series D Preferred Conversion Price shall be adjusted as provided in Section D.7(d) hereof, the Corporation shall file, at its principal office, at the office of the transfer agent for the Series D Preferred Stock, if any, or at such other place as may be designated by the Corporation, a statement, signed by its President and by its Chief Financial Officer, showing in detail the facts requiring such adjustment and the Series D Preferred Conversion Price that shall be in effect after such adjustment. The Corporation shall also cause a copy of such statement to be sent by first-class, certified mail, return receipt 51. <PAGE> requested, postage prepaid, to each Series D Preferred Stockholder at such holder's address appearing on the Corporation's records. Where appropriate, such copy may be given in advance and may be included as part of a notice required to be mailed under the provisions of Section D.7(e)(ii) hereof. (ii) In the event the Corporation shall propose to file a registration statement under the Securities Act for a Public Offering or to take any action of the types described in clauses (i), (ii), (iii) or (iv) of Section D.7(d) hereof, the Corporation shall give notice to each Series D Preferred Stockholder, in the manner set forth in Section D.7(e)(i) hereof, which shall specify the record date, if any, with respect to any such action and the date on which such action is to take place. The notice shall also set forth such facts as are reasonably necessary to indicate the effect of such action (to the extent such effect may be known at the date of such notice) on the Series D Preferred Conversion Price and the number, kind or class of shares or other securities or property which shall be deliverable or purchasable upon the occurrence of such action or deliverable upon conversion of shares of Series D Preferred Stock. In the case of any action which would require the fixing of a record date, such notice shall be given at least ten (10) days prior to the date so fixed, and in case of all other action, such notice shall be given at least fifteen (15) days prior to the taking of such proposed action. Failure to give notice under this Section D.7(e)(ii), or any defect therein, shall not affect the legality or validity of any such action. f. Transfer Taxes. The Corporation shall pay all documentary, stamp or other transactional taxes (excluding income taxes) attributable to the issuance or delivery of shares of capital stock of the Corporation upon conversion of any shares of Series D Preferred Stock; provided, however, that the Corporation shall not be required to pay any taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificate for such shares in a name other than that of the holder of the shares of Series D Preferred Stock in respect of which such shares are being issued. g. Reservation of Common Stock. The Corporation shall at all times reserve, free from preemptive rights, out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of Series D Preferred Stock, sufficient shares of Common Stock to provide for the conversion of all outstanding shares of Series D Preferred Stock. h. Status of Common Stock. All shares of Common Stock which may be issued in connection with the conversion provisions set forth herein will, upon issuance by the Corporation, be validly issued, fully paid and nonassessable, free from preemptive rights and free from all taxes, liens or charges with respect thereto created or imposed by the Corporation. 8. Redemption. a. On and after the Series B Preferred Fifth Anniversary Date or at any time if an Event of Noncompliance is declared in accordance with the Stockholders' Agreement, at the written request of the holders of shares representing not less than 75% of the combined voting power of the Series A, Series B, Series C and Series D Preferred Stock then 52. <PAGE> outstanding, voting together as a single class, made, from time to time, at any date on or after the Series B Preferred Fifth Anniversary Date or upon the declaration of an Event of Noncompliance, the Corporation shall redeem (unless otherwise prevented by law) all of the shares of Series A, Series B and Series D Preferred Stock, at a redemption price per share for each such series of Series Preferred Stock equal to (i) the Series A Preferred Original Purchase Price, the Series B Preferred Original Purchase Price or the Series D Preferred Original Purchase Price, as applicable, plus (ii) an amount equal to any accrued but unpaid cumulative dividends thereon and any declared but unpaid dividends thereof, and, then, all of the shares of Series C Preferred Stock, at a redemption price per share for such Series C Preferred Stock equal to (i) the Series C Preferred Original Purchase Price plus (ii) an amount equal to any accrued but unpaid dividends thereon and any declared but unpaid dividends thereon. For purposes of determining whether the requisite 75% of the holders of Series A, Series B, Series C and Series D Preferred Stock are participating in the Redemption Notice, each share of issued and outstanding Series A, Series B, Series C and Series D Preferred Stock shall entitle the holder thereof to one vote per share for each share of Common Stock (including fractional shares) into which each share of Series A, Series B, Series C and Series D Preferred Stock is then convertible, rounded to the nearest one-tenth of a share. b. On and after the Redemption Date, all rights of any Series D Preferred Stockholder with respect to the shares of Series D Preferred Stock redeemed on that Redemption Date, except the right to receive the Redemption Payment as provided herein, shall cease, and such shares shall no longer be deemed to be outstanding, whether or not the Corporation has received the certificates representing such shares, on the condition that the Corporation pays the Redemption Payment, or irrevocably deposits or sets aside cash in an amount equal to the Redemption Payment; provided, however, that if the Corporation defaults in the payment of the Redemption Payment, the rights of the holder with respect to such shares of Series D Preferred Stock shall continue until the Corporation cures such default. c. The Requesting Holders shall send their Redemption Notice pursuant to this Section D.8 by first-class, certified mail, return receipt requested, postage prepaid, to the Corporation at its principal place of business or to any transfer agent of the Corporation. The Corporation shall fix a date for redemption which shall not be more than 60 days after the receipt of Redemption Notices from the Requesting Holders. Not less than 45 days prior to the Redemption Date, written notice shall be mailed, first class postage prepaid, to each holder of record (at the close of business on the business day next preceding the day on which notice is given) of the Series A, Series B, Series C and Series D Preferred Stock, at the address last shown on the records of the Corporation for such holder or given by the holder to the Corporation for the purpose of notice, notifying such holder of the redemption to be effected, the Redemption Date fixed, the Redemption Payment, the place at which payment may be obtained and the date on which such holder's conversion rights as to such shares terminate and calling upon such holder to surrender to the Corporation, in the manner and at the place designated, such holder's certificate or certificates representing the shares to be redeemed. In the event of only a partial redemption of the outstanding shares of the Series A, Series B and Series D Preferred Stock entitled to redemption for any reason, the redemption of the Series A, Series B and Series D Preferred Stock shall be pro rata based upon the total amount that would be paid by the Corporation to each Series A, Series B and Series D Preferred Stockholder if all of the shares of Series A, Series B and Series D Preferred Stock were fully redeemed pursuant to Sections 53. <PAGE> A.8(a), B.8(a) and D.8(a) hereof. At any time on or after the Redemption Date, the holders of the Series D Preferred Stock shall be entitled to receive the Redemption Payment for each of the shares of Series D Preferred Stock held by such holder which are to be redeemed by the Corporation upon actual delivery to the Corporation or its transfer agent of the certificate(s) representing the shares to be redeemed. Upon redemption of only a portion of the number of shares covered by a Series D Preferred Stock certificate, the Corporation shall issue and deliver to or upon the written order of the holder of such Series D Preferred Stock certificate, at the expense of the Corporation, a new certificate covering the number of shares of Series D Preferred Stock being redeemed representing the unredeemed portion of the Series D Preferred Stock certificate, which new certificate shall entitle the holder thereof to all the rights, powers and privileges of a holder of such shares. d. Notwithstanding anything to the contrary contained in this Section D.8, the Corporation shall not be obligated to acquire any shares on any Redemption Date to the extent that the acquisition thereof would violate any law, statute, rule, regulation, policy or guideline promulgated by any federal, state, local or foreign governmental authority applicable to the Corporation, provided that the Corporation shall use all legally permissible methods in the reduction of capital and revaluation of assets, including appraisal, in order to obtain a legal source of funds with which to pay the Redemption Payment and shall acquire such shares as soon as permitted by applicable laws, statutes, rules, regulations, policies and guidelines. 9. Miscellaneous. a. Shares of Series D Preferred Stock are not subject to or entitled to the benefit of a sinking fund. b. Redeemed shares of Series D Preferred Stock shall not be reissued but shall be retired. Upon the retirement of redeemed shares the capital of the Corporation shall be reduced. c. The shares of the Series D Preferred Stock shall not have any preferences, voting powers or relative, participating, optional, preemptive or other special rights except as set forth above in this Seventh Restated Certificate of Incorporation of the Corporation. PART E. Series E Convertible Preferred Stock. 1. Terms. The number of shares, powers, terms, conditions, designations, preferences and privileges, relative, participating, optional and other special rights, and qualifications, limitations and restrictions, if any, of the Series E Preferred Stock shall be as set forth herein. 2. Ranking. The Corporation's Series E Preferred Stock shall rank, as to dividends and upon Liquidation, (x) junior to the Series A, Series B and Series D Preferred Stock (but, with respect to Liquidation, only to the extent provided in Sections A.4, B.4, C.4, D.4 and E.4 hereof), (y) pari passu with the Series C Preferred Stock and (z) senior and prior to the Common Stock and to all other classes or series of stock issued by the Corporation. The Series E Preferred Stock shall have the following designations, powers, preferences, relative, participating, optional or other special rights, qualifications, limitations and restrictions: 54. <PAGE> 3. Dividends. a. Dividends are payable on the Series E Preferred Stock, when, as and if declared by the Board of Directors. Whenever any dividend or other distribution is declared on any shares of Series E Preferred Stock, the Board of Directors shall simultaneously declare a dividend or distribution at the same percentage rate and in the same form on each other outstanding share of Series E and each outstanding share of Series C Preferred Stock, so that all outstanding shares of Series E and Series C Preferred Stock will participate equally with each other ratably per share. b. So long as any Series E Preferred Stock is outstanding the Corporation shall not declare or pay any dividend or make any distribution (whether in cash, shares of capital stock of the Corporation or other property) on shares of its Common Stock or any other class or series of stock ranking pari passu with or junior to the Series E Preferred Stock, unless prior thereto or simultaneously therewith all dividends and distributions previously declared on the Series E Preferred Stock shall have been paid or the Corporation shall have irrevocably deposited or set aside cash or United States Obligations sufficient for the payment thereof. c. If the Board of Directors declares dividends or other distributions (other than (i) on Liquidation, (ii) on the Series A Preferred Stock pursuant to Section A.3(d) hereof, (iii) on the Series B Preferred Stock pursuant to Section B.3(d) hereof, or (iv) on the Series D Preferred Stock pursuant to Section D.3(d) hereof) on the Common Stock or any other class or series of stock ranking pari passu with or junior to the Series E Preferred Stock in cash, property or securities (excluding Common Stock) of the Corporation (or subscription or other rights to purchase or acquire securities (excluding Common Stock) of the Corporation), the Board of Directors shall simultaneously declare a dividend or distribution on the same terms, at the same or equivalent rate, and in the same form on each share of Series E Preferred Stock, so that all outstanding shares of Series E Preferred Stock will participate ratably with the Common Stock and each other class or series of stock ranking pari passu with or junior to the Series E Preferred Stock in such dividend or distribution. For purposes of determining its proportional share of the dividend or distribution, each share of the Series E Preferred Stock and any other applicable class or series of convertible securities shall be deemed to be that number of shares of Common Stock into which such share is then convertible, rounded to the nearest one-tenth of a share. 4. Rights on Liquidation, Dissolution, Winding-Up. a. With respect to rights on Liquidation, the Series E Preferred Stock shall rank (x) junior to the Series A, Series B and Series D Preferred Stock (but only to the extent provided in this Section E.4), (y) pari passu with the Series C Preferred Stock and (z) senior and prior to the Common Stock and to all other classes or series of stock issued by the Corporation. b. Subject to the rights of the holders of Series A Preferred Stock set forth in Section A.4 hereof, the holders of Series B Preferred Stock set forth in Section B.4 hereof, the holders of Series C Preferred Stock set forth in Section C.4 hereof and the holders of Series D Preferred Stock set forth in Section D.4 hereof, in the event of any Liquidation, whether 55. <PAGE> voluntary or involuntary, before any payment of cash or distribution of other property shall be made to the Common Stockholders or any other class or series of stock ranking on Liquidation junior to the Series E Preferred Stock, the holders of Series E Preferred Stock shall be entitled to receive out of the assets of the Corporation legally available for distribution to its stockholders, pari passu with the rights of the Series C Stockholders, an amount per share equal to the Series E Preferred Liquidation Preference whether from capital, surplus or earnings, plus an amount equal to any accrued but unpaid cumulative dividends thereon and any declared but unpaid dividends thereon. c. If, upon any Liquidation, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the Series E Preferred Stockholders the full amounts to which each of them shall be entitled pursuant to Section E.4(b) hereof and to pay the Series C Preferred Stockholders the full amount to which each of them shall be entitled pursuant to Section C.4(b) hereof, then the Series E and Series C Preferred Stockholders shall share ratably in any distribution of assets according to the respective amounts which would be payable to them in respect of the shares of Series E or Series C Preferred Stock, as the case may be, held upon such distribution if all amounts payable on or with respect to such shares were paid in full pursuant to Sections E.4(b) and C.4(b) hereof. d. In the event of any Liquidation, the Series E Preferred Stock shall not be entitled to receive any payment of cash or distribution of property other than as expressly provided in this Section E.4. 5. Merger, Consolidation, etc. a. In the event the Corporation intends to sell, lease or otherwise dispose of all or substantially all of the assets of the Corporation, effect any transaction or series of related transactions in which more than 50% of the voting power of the Corporation is transferred (other than in connection with a Public Offering), or merge or consolidate with or into any other corporation, corporations or other entity or entities (other than a merger or consolidation in which the Series Preferred Stockholders receive securities of the surviving corporation having substantially similar rights to the Series Preferred Stock and in which the stockholders of the Corporation immediately prior to such a transaction are holders of at least a majority of the voting securities of the surviving corporation immediately thereafter), then the Corporation shall give written notice to each Series Preferred Stockholder no less than 20 days prior to the closing of any such transaction notifying the Series Preferred Stockholders of the terms and timing of the closing of such transaction and of the rights of the Series Preferred Stockholders under Sections A.5(b), B.5(b), C.5(b), D.5(b) and E.5(b) hereof. b. Upon the affirmative vote of the holders of not less than 75% in voting power of all of the shares of Series Preferred Stock then outstanding, voting together as a separate class, made prior to the consummation of such transaction, the proceeds of or any property deliverable from such transaction shall be distributed among the holders of the Series Preferred Stock and the Common Stock according to the provisions of Sections A.4, B.4, C.4, D.4 and E.4 hereof as if such transaction were a Liquidation. 56. <PAGE> c. The voting rights of the holders of Series Preferred Stock contained in Sections A.5(b), B.5(b), C.5(b), D.5(b) and E.5(b) hereof may be exercised at a special meeting of the holders of Series Preferred Stockholders called as provided in accordance with the By-laws of the Corporation or by written consent of the holders of Series Preferred Stock in lieu of a meeting. 6. Voting. a. General. In addition to the rights otherwise provided for herein or by law, except as provided in Section E.6(b) hereof, the Series E Preferred Stockholders shall be entitled to vote, together with the Series A Preferred Stockholders, the Series B Preferred Stockholders, the Series C Preferred Stockholders, the Series D Preferred Stockholders, the Series E Preferred Stockholders and the Common Stockholders and any other class or series of stock then entitled to vote, as one class on all matters as to which Common Stockholders shall be entitled to vote, in the same manner and with the same effect as the Common Stockholders, except as otherwise required by the General Corporation Law. In any such vote, and in any vote or action of the Series E Preferred Stockholders voting together as a separate class or with the other holders of Series Preferred Stock as a separate class, each share of issued and outstanding Series E Preferred Stock shall entitle the holder thereof to one vote per share for each share of Common Stock (including fractional shares) into which each share of Series E Preferred Stock is then convertible, rounded to the nearest one-tenth of a share. b. Election of Board of Directors. The Series E Preferred Stockholders shall not have any right to vote for the election of members to the Board of Directors of the Corporation. c. Protective Provisions. So long as any Series Preferred Stock is outstanding, the Corporation shall not, without the written consent in lieu of a meeting, or the affirmative vote at a meeting called for such purpose, of the holders of shares representing at least 75% of the combined voting power of the issued and outstanding Series A, Series B, Series C, Series D and Series E Preferred Stock, voting together as a single class: (i) except for "Excluded Stock", authorize, issue or agree to authorize or issue any shares of capital stock of the Corporation, any right, warrant, or option to receive any capital stock, or any security convertible into or exchangeable for capital stock or any capitalized lease with any equity feature with respect to the capital stock of the Corporation; (ii) change as a whole, by subdivision or combination in any manner, the number of shares of the Common Stock then outstanding into a different number of shares, with or without par value, without making the identical change as a whole in the number of shares of Series Preferred Stock then outstanding; (iii) amend, alter or repeal, in any manner whatsoever, the designations, powers, preferences, relative, participating, optional or other special rights, qualifications, limitations and restrictions of the Series Preferred Stock; (iv) sell, abandon, transfer, lease or otherwise dispose of all or substantially all of the properties or assets of the Corporation or any of its subsidiaries; 57. <PAGE> (v) declare or pay any dividend (other than as required by Section A.3(d) hereof in respect of the Series A Preferred Stock, by Section B.3(d) hereof in respect of the Series B Preferred Stock and by Section D.3(d) hereof in respect of the Series D Preferred Stock) or make any distribution (whether in cash, shares of capital stock of the Corporation, or other property) on shares of its capital stock other than the Series Preferred Stock; (vi) merge or consolidate with or into, or permit any subsidiary of the Corporation to merge or consolidate with or into, any other corporation, corporations or other entity or entities, or effect any transaction or series of related transactions in which more than 50% of the voting power of the Corporation is transferred (other than in connection with a Public Offering); (vii) voluntarily dissolve, liquidate or wind-up or carry out any partial Liquidation or distribution or transaction in the nature of a partial Liquidation or distribution; (viii) increase the number of shares of any series of Preferred Stock of the Corporation authorized to be issued; (ix) reclassify any shares of the Corporation's capital stock as shares ranking senior to or on parity with the Series Preferred Stock with respect to rights on Liquidation, redemption or for the payment of any dividend or distribution other than in Liquidation; (x) amend, alter or repeal any provision of the Certificate of Incorporation of the Corporation; (xi) amend, alter or repeal any provisions of the By-laws of the Corporation so as to adversely affect the rights of the holders of the Series Preferred Stock; or (xii) directly or indirectly, redeem, purchase or otherwise acquire for value (including through an exchange), or set apart money or other property for any mandatory purchase or other analogous fund for the redemption, purchase or acquisition of, any shares of Common Stock, except (a) pursuant to Sections A.8, B.8, C.8 and D.8 hereof, and (b) pursuant to any agreement approved by the Board of Directors with an officer, director, employee or consultant providing for the repurchase of any capital stock of the Corporation owned by such officer, director, employee or consultant at the option of the Corporation, which is either (A) set forth on Schedule 4.10 of the Series B Stock Purchase Agreement, or (B) issued pursuant to the Option Plan, as amended prior to May 13, 1996, the 1997 Equity Incentive Plan, or any other stock option plan of the Corporation or one or more amendments to the Option Plan, from and after May 13, 1996, approved by the Board of Directors and by the holders of 75% of the then issued and outstanding Series Preferred Stock, voting together as a separate class. In any vote or written consent in lieu of a meeting pursuant to this Section E.6(c) and Sections A.6(c), B.6(c), C.6(c) and D.6(c) hereof, each share of issued and outstanding Series Preferred Stock shall entitle the holder thereof to the number of votes per share that equals the number of 58. <PAGE> shares of Common Stock (including fractional shares) into which each such share is then convertible, rounded to the nearest one-tenth of a share. 7. Conversion. a. Right to Convert. (i) Any Series E Preferred Stockholder shall have the right, at any time or from time to time, prior to the Closing Date to convert any or all of its shares of Series E Preferred Stock into that number of fully paid and nonassessable shares of Common Stock for each share of Series E Preferred Stock so converted equal to the quotient of the Series E Preferred Original Purchase Price divided by the Series E Preferred Conversion Price (as last adjusted and then in effect) rounded to the nearest one-tenth of a share. (ii) (a) Any Series E Preferred Stock that remains unconverted on the Closing Date shall be automatically converted without notice and without any action on the part of the holder thereof into shares of Common Stock on the Closing Date in accordance with the preceding sentence. After the Closing Date all rights of holders of shares of Series E Preferred Stock with respect to Series E Preferred Stock, except the right to receive shares of Common Stock in accordance with this Section E.7(a)(ii)(a) and any accrued but unpaid dividends and any declared but unpaid dividends as in accordance with Section E.7(a)(ii)(c) hereof, shall cease and the shares of Series E Preferred Stock shall no longer be deemed to be outstanding, whether or not the Corporation has received the certificates representing such shares. (b) The Corporation shall promptly send by first- class mail, postage prepaid, to each Series E Preferred Stockholder at such holder's address appearing on the Corporation's records a copy of (i) each registration statement filed by the Corporation under the Securities Act and each amendment thereof and each exhibit and schedule thereto and (ii) each order of the Securities and Exchange Commission declaring any such registration statement to be effective. (c) Holders of Series E Preferred Stock converted into shares of Common Stock pursuant to this Section E.7 shall be entitled to payment of any accrued but unpaid cumulative dividend and any declared but unpaid dividends payable with respect to such shares of Series E Preferred Stock, up to and including the Conversion Date or the Closing Date, as the case may be. b. Mechanics of Conversion. (i) Any Series E Preferred Stockholder that exercises its right to convert its shares of Series E Preferred Stock into Common Stock shall deliver the Preferred Certificate, duly endorsed or assigned in blank to the Corporation, during regular business hours, at the office of the transfer agent of the Corporation, if any, at the principal place of business of the Corporation or at such other place as may be designated by the Corporation. (ii) Each Preferred Certificate shall be accompanied by written notice stating that such holder elects to convert such shares and stating the name or names (with 59. <PAGE> address) in which the Common Certificate(s) are to be issued. Such conversion shall be deemed to have been effected on the date when the aforesaid delivery is made. (iii) As promptly as practicable thereafter, the Corporation shall issue and deliver to or upon the written order of such holder, at the place designated by such holder, the Common Certificate(s) for the number of full shares of Common Stock to which such holder is entitled and a cash payment for any fractional interest in a share of Common Stock, as provided in Section E.7(c) hereof, and for any accrued but unpaid cumulative dividends and any declared but unpaid dividends, payable with respect to the converted shares of Series E Preferred Stock, up to and including the Conversion Date or the Closing Date, as the case may be. (iv) The person in whose name each Common Certificate is to be issued shall be deemed to have become a stockholder of record of Common Stock on the Conversion Date or the Closing Date, as the case may be, unless the transfer books of the Corporation are closed on that date, in which event such holder shall be deemed to have become a stockholder of record on the next succeeding date on which the transfer books are open; provided, that the Series E Preferred Conversion Price shall be that in effect on the Conversion Date or the Closing Date, as the case may be. (v) Upon conversion of only a portion of the shares of Series E Preferred Stock covered by a Preferred Certificate, the Corporation, at its own expense, shall issue and deliver to or upon the written order of the holder of such Preferred Certificate, a new certificate representing the number of unconverted shares of Series E Preferred Stock from the Preferred Certificate so surrendered. c. Issuance of Common Stock on Conversion. (i) If a Series E Preferred Stockholder shall surrender more than one Preferred Certificate for conversion at any one time, the number of such shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Series E Preferred Stock so surrendered. (ii) No fractional shares of Common Stock shall be issued upon conversion of shares of Series E Preferred Stock. The Corporation shall pay a cash adjustment for such fractional interest in an amount equal to the then Current Market Price of a share of Common Stock multiplied by such fractional interest. d. Conversion Price; Adjustment. The "Series E Preferred Conversion Price" with respect to the Series E Preferred Stock shall initially be equal to the Series E Preferred Original Purchase Price and shall be subject to adjustment from time to time as follows: (i) If the Corporation shall at any time after the Series E Preferred Original Issuance Date fix a record date for the subdivision, split- up or stock dividend of shares of Common Stock, then, following the record date fixed for the determination of holders of Common Stock entitled to receive such subdivision, split-up or dividend (or the date of such subdivision, split-up or dividend, if no record date is fixed), the Series E Preferred Conversion Price shall be appropriately decreased so that the number of shares of Common 60. <PAGE> Stock issuable on conversion of each share of the Series E Preferred Stock shall be increased in proportion to such increase in outstanding shares. (ii) If, at any time after the Series E Preferred Original Issuance Date, the number of shares of Common Stock outstanding is decreased by a combination of the outstanding shares of Common Stock, then, following the record date fixed for such combination (or the date of such combination, if no record date is fixed), the Series E Preferred Conversion Price shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of Series E Preferred Stock shall be decreased in proportion to such decrease in outstanding shares. (iii) If, at any time after the Series E Preferred Original Issuance Date, an Extraordinary Transaction is consummated, the Series E Preferred Conversion Price with respect to the Series E Preferred Stock outstanding after the Extraordinary Transaction shall be adjusted to provide that the shares of Series E Preferred Stock outstanding immediately prior to the effectiveness of the Extraordinary Transaction shall be convertible into the kind and number of shares of stock or other securities or property of the Corporation or of the corporation resulting from or surviving such Extraordinary Transaction which the holder of the number of shares of Common Stock deliverable (immediately prior to the effectiveness of the Extraordinary Transaction) upon conversion of such Series E Preferred Stock would have been entitled to receive upon such Extraordinary Transaction.

If the Company desires to purchase all of the remaining Offered Shares it shall seek the approval of the holders of at least 75% in interest of the Preferred Shares (excluding those Preferred Shares owned or held by the Selling Stockholder and any Tag-Along Stockholder pursuant to paragraph (j) below), voting together as a class. Upon obtaining the requisite approval from the Preferred Stockholders, the Company shall communicate in writing its acceptance to the Selling Stockholder and the other Stockholders, which Acceptance shall be delivered in person or mailed to the Selling Stockholder and the other Stockholders within thirty (30) days of the date the Offer was made. (f) Sale of the Offered Shares pursuant to this Section 3.4 shall be made at the offices of the Company no later than the thirtieth (30) day following the expiration of the 30-day 14. <PAGE> period after the Offer is made (or if such thirtieth (30) day is not a Business Day, then on the next succeeding Business Day). Such sales shall be effected by the Selling Stockholder's delivery to each Purchasing Stockholder or the Company, as the case may be, of a certificate or certificates evidencing the Offered Shares to be purchased by it or him, duly endorsed for transfer to the Purchasing Stockholder or the Company, as the case may be, which Offered Shares shall be delivered free and clear of all liens, charges, claims and encumbrances of any nature whatsoever, against payment to the Selling Stockholder of the purchase price therefor by the Purchasing Stockholder or Company, as the case may be. Payment for the Offered Shares shall be made as provided in the Offer or by wire transfer or certified check. (g) If the Purchasing Stockholders and the Company do not agree to purchase all of the Offered Shares, then the Offered Shares may be sold by the Selling Stockholder at any time within 120 days after the date the Offer was made. Any such sale shall be to the Proposed Transferee, at not less than the price and upon other terms and conditions, if any, not more favorable to the Proposed Transferee than those specified in the Offer. Any Offered Shares not sold within such 120-day period shall continue to be subject to the requirements of a prior offer pursuant to this Section 3.4. (h) If any Selling Stockholder becomes obligated to sell any Shares (a "Defaulting Stockholder") to the Company or any Purchasing Stockholder under this Agreement and fails to deliver such Shares in accordance with the terms of this Agreement, the Company or the Purchasing Stockholder, as the case may be, may, at its or his option, in addition to all other remedies it or he may have, send to the Defaulting Stockholder the purchase price for such Shares as is herein specified. Thereupon, the Company, upon written notice to the Defaulting Stockholder, if applicable, shall (x) cancel on its books the certificate or certificates representing the Shares to be sold and (y) issue, in lieu thereof, in the name of the Purchasing Stockholder, a new certificate or certificates representing such Shares, and thereupon all of the Defaulting Stockholder's rights in and to such Shares shall terminate, except for the right to receive payment of the purchase price therefor. (i) Notwithstanding anything herein to the contrary, the Selling Stockholder shall not be obligated to sell any Shares to the Company or the other Stockholders, and will be free to sell all of the Shares to the Proposed Transferee, if the Company and the Stockholders do not elect to buy all of the Shares specified in the Offer. (j) In lieu of exercising the Right of First Refusal, each of the other Stockholders (for the purposes of this paragraph, the "Tag-Along Stockholder") shall have the irrevocable right (the "Tag-Along Right") to require the Selling Stockholder to cause the Proposed Transferee to purchase from such Tag-Along Stockholder that number of Shares held by such Tag-Along Stockholder as is equal to the product of the Offered Shares, multiplied by a fraction, the numerator of which is the number of Shares held by such Tag-Along Stockholder and the denominator of which is the number of Shares owned by such Tag-Along Stockholder plus the sum of the number of Shares owned by the Selling Stockholder and all other Tag-Along Stockholders who are exercising their Tag- Along Rights (the "Tag-Along Shares"). The sale of the Offered Shares (as reduced by the Tag-Along Shares, the "Remaining Offered Shares") and the Tag- Along Shares shall be for the same consideration and otherwise on the same terms and conditions for all holders. The Tag-Along Right shall be exercised by a Tag- Along Stockholder 15. <PAGE> by notifying the Selling Stockholder and the Company in writing (the "Tag-Along Notice") within twenty (20) calendar days of receiving the Offer of his intention to sell his Tag-Along Shares. Failure by any Stockholder to deliver a Tag-Along Notice during such twenty (20) calendar day period shall be deemed to constitute the election of such Stockholder not to exercise his Tag-Along Rights. If the Proposed Transferee does not consummate the purchase of all of the Remaining Offered Shares and the Tag-Along Shares within 120 calendar days from the receipt by the Selling Stockholder of a Tag-Along Notice from each of the other Stockholders, the Offered Shares and Tag-Along Shares shall again become subject to the terms of this Section 3. 4. Rights to Purchase Additional Stock. (a) Except for Excluded Stock, the Covenant Preferred Stockholders shall have the right to subscribe to any and all issuances of Capital Stock of the Company ("Company Offered Shares"). Each Covenant Preferred Stockholder shall have the right to purchase that number of Company Offered Shares as shall be equal to the number of Company Offered Shares multiplied by a fraction, the numerator of which shall be the number of Shares then owned by such Covenant Preferred Stockholder and the denominator of which shall be the aggregate number of Shares then owned by all of the Covenant Preferred Stockholders (the "Fraction"). For purposes of calculating the Fraction, all issued and outstanding securities held by the Covenant Preferred Stockholders that are convertible into or exercisable or exchangeable for shares of Common Stock (including any issued and issuable Covenant Preferred Shares) or for any such convertible, exercisable or exchangeable securities, shall be treated as having been so converted, exercised or exchanged. (b) In the event the Company shall propose to issue Capital Stock except for Excluded Stock, the Company shall give written notice (the "Offer of Shares") to each Covenant Preferred Stockholder, which shall set forth the number and kind or class of shares of Capital Stock proposed to be issued, the terms and conditions thereof and the price therefor. Such notice shall be given at least twenty (20) days prior to the issuance of such Capital Stock. (c) The Offer of Shares by its terms shall remain open and irrevocable for a period of twenty (20) days from the date of its delivery to such Covenant Preferred Stockholder ("20-Day Period"). (d) Each Covenant Preferred Stockholder shall evidence its acceptance of the Offer of Shares by delivering a written notice ("Notice of Acceptance"), signed by the Covenant Preferred Stockholder, setting forth the number of Company Offered Shares which the Covenant Preferred Stockholder elects to purchase. The Notice of Acceptance must be delivered to the Company prior to the end of the 20-Day Period. (e) If the Covenant Preferred Stockholders do not tender Notices of Acceptance for all of the Company Offered Shares, the Company shall have ninety (90) days from the expiration of the 20-Day Period to sell all or any part of the Company Offered Shares refused by the Covenant Preferred Stockholders to any Person(s), but only upon terms and conditions which are in all material respects no more favorable to such other Person(s) than those set forth in the Offer of Shares. 16. <PAGE> (f) Upon the closing of the sale of Company Offered Shares to any third party (which shall include full payment of the purchase price to the Company), each Covenant Preferred Stockholder shall (i) purchase from the Company, and the Company shall issue and sell to such Covenant Preferred Stockholder, any Company Offered Shares for which such Covenant Preferred Stockholder tendered a Notice of Acceptance upon the terms specified in the Offer of Shares and (ii) execute and deliver an agreement restricting transfer of such Company Offered Shares substantially as set forth in Section 3 of this Agreement. (g) In each case, any Company Offered Shares not purchased either by the Covenant Preferred Stockholders or by any other Person in accordance with this Section 4 may not be sold or otherwise disposed of until they are again offered to the Covenant Preferred Stockholder under the procedures specified in this Section 4. (h) If the Capital Stock to be issued by the Company is to be issued pursuant to a Public Offering (i) notwithstanding the time periods set forth above, the Company may require that the Covenant Preferred Stockholders make an election to either (A) commit to purchase shares of Capital Stock from the Company at a price no higher than the public offering price at the closing of the Public Offering or (B) waive their rights to subscribe for additional shares of Common Stock to be issued in the Public Offering, (ii) the subscription right shall not be applicable to shares issuable if the underwriters exercise their over-allotment option; and (iii) the amount to be purchased pursuant to this Section 4(h) may be reduced if in the written opinion of the managing underwriters of the Public Offering, the purchase of such number of shares by the Covenant Preferred Stockholders would adversely impact the Public Offering. Such election shall be made sufficiently in advance of the filing of the registration statement relating to the Public Offering as shall be reasonably requested by the Company. (i) The rights provided by this Section 4 may be assigned by any Covenant Preferred Stockholder which is a limited partnership or a trust to any and all members of its Group, provided, that all such rights of any assignee to purchase Company Offered Shares will be subject to receipt of appropriate representations from such assignee as reasonably requested by the Company to ensure compliance with all applicable securities laws. 5.

If the holders of Registrable Securities who requested the registration of Registrable Securities engage one or more underwriters to distribute such Registrable Securities, the Company shall permit the managing underwriter(s) and counsel to the underwriter(s) at the Company's expense to visit and inspect any of the properties of the Company, examine its books, take copies and extracts therefrom and discuss the affairs, finances and accounts of the Company with its officers, employees and public accountants (and by this provision the Company hereby authorizes said accountants to discuss with such underwriter(s) and such counsel its affairs, finances and accounts), at reasonable times and upon reasonable notice, with or without a representative of the Company being present. The Company shall have the right to include in any registration of Registrable Securities required 30. <PAGE> pursuant to this Section 11.2 additional shares of its Common Stock to be issued by the Company ("Company Securities") or shares of Common Stock ("Third Party Registrable Securities") that have the benefit of duly exercised registration rights contractually binding on the Company, provided that if any Registrable Securities to be so registered for sale are to be distributed by or through underwriters, then all Registrable Securities to be so registered for sale and Company Securities and Third Party Registrable Securities, if any, shall be included in such underwriting on the same terms and provided, however, that if, in the written opinion of the managing underwriter(s), the total amount of such securities to be registered will exceed the maximum amount of the Company's securities which can be marketed (i) at a price reasonably related to their then current market value, or (ii) without otherwise materially and adversely affecting the entire offering, then the Company shall exclude from such underwriting (x) first, the maximum number of Company Securities and Third Party Registrable Securities as is necessary in the opinion of the managing underwriter(s) to reduce the size of the offering and (y) then, the minimum number of Registrable Securities, pro rata to the extent practicable, on the basis of the number of Registrable Securities requested to be registered among the participating holders of Registrable Securities, as is necessary to reduce the size of the offering. A registration that covers both Registrable Securities, Company Securities and Third Party Registrable Securities shall be deemed to have been requested pursuant to a Request for Registration pursuant to the applicable subsection Section 11.1 if the Registrable Securities of the type covered by such subsection constitute at least 50% of the total offering on the effective date of the registration statement but shall not be deemed to be one of the registrations referred to in the applicable subsection of Section 11.1 hereof if Registrable Securities of the type covered by such subsection constitute less than 50% of the total offering on the effective date of the registration statement. 11.3 "Piggyback" Registrations.

Upon the request of any holder of Registrable Securities given within twenty (20) days after the Company has given such notice, the Company will cause the Registrable Securities which the Company has been requested to register by such holder of Registrable Securities to be registered under the Securities Act, all to the extent requisite to permit the sale or other disposition by such holder of Registrable Securities of the Registrable Securities so registered. (b) If securities are to be registered for sale under a registration not initiated by a Request for Registration and are to be distributed by or through a firm of underwriters, then any Registrable Securities which the Company has been requested to register pursuant to clause (a) of this Section 11.3 shall also be included in such underwriting on the same terms as other securities of the same class as the Registrable Securities included in such underwriting, provided that if, in the written opinion of the managing underwriter(s), the total amount of such securities to be so registered, when added to the Registrable Securities and the securities held by holders of securities other than the Registrable Securities, if any, will exceed the maximum amount of the 31. <PAGE> Company's securities which can be marketed (i) at a price reasonably related to their then current market value, or (ii) without otherwise materially and adversely affecting the entire offering, then (subject to clause (d) of this Section 11.3) the Company shall exclude from such underwriting (x) first, the maximum number of securities, if any, other than Registrable Securities, being sold for the account of persons other than the Company as is necessary to reduce the size of the offering and (y) second, the minimum number of Registrable Securities, if any, as is necessary in the opinion of the managing underwriter(s) to reduce the size of the offering (any such reduction in Registrable Securities to be made pro rata to the extent practicable on the basis of the number of Registrable Securities requested to be registered among the participating holders of Registrable Securities). (c) If securities are to be registered for sale under a registration not initiated by a Request for Registration and are to be distributed for the account of holders of Third Party Registrable Securities or holders (other than the Company) of other securities of the Company other than Registrable Securities by or through a firm of underwriters of recognized standing under underwriting terms appropriate for such transaction, then any Registrable Securities which the Company has been requested to register pursuant to clause (a) of this Section 11.3 shall also be included in such underwriting on the same terms as other securities included in such underwriting, provided that if, in the written opinion of the managing underwriter or underwriters, the total amount of such securities to be so registered, when added to such Registrable Securities, will exceed the maximum amount of the Company's securities which can be marketed (i) at a price reasonably related to their then current market value, or (ii) without otherwise materially and adversely affecting the entire offering, then the Company shall exclude from such underwriting the number of Registrable Securities and other securities, pro rata to the extent practicable, on the basis of the number of securities requested to be registered, as is necessary in the opinion of the managing underwriter(s) to reduce the size of the offering. (d) Notwithstanding Section 11.3 (a) and (b), the Company shall not exclude more Registrable Securities from registration than is necessary to reduce the number of Registrable Securities to be registered to one-fifth of the total number of securities to be registered, provided, however, that the Company may exclude all Registrable Securities from registration in connection with the Company's Initial Public Offering in its sole discretion, whether or not such exclusion is required in the opinion of the managing underwriter(s). (e) Notwithstanding anything to the contrary contained herein, the provisions of clause (y) of Section 11.3(b) and the provisions of Section 11.3(d) limiting the amount of the Registrable Securities requested to be registered that may be excluded from such registration may be waived by the affirmative vote of holders of 50% of the Registrable Securities requested to be registered. If, by reason of the provisions of Section 11.3(b) or Section 11.3(d), in any public offering other than the Company's Initial Public Offering, more than 10% of the Registrable Securities requested to be registered are excluded from such registration statement, then, in each such case, the holders of the Registrable Securities shall be entitled to an additional demand registration pursuant to Section 11.1(e) and shall be entitled to an additional registration pursuant to Section 11.1 at the Company's expense, without reimbursement, in accordance with Section 11.6. 32. <PAGE> 11.4 Registrations on S-3. At such time as the Company shall have qualified for the use of Form S-3 (or any successor form promulgated under the Securities Act), each holder of Registrable Securities shall have the right to request in writing an unlimited number of registrations on Form S-3 (except that the holders of Series E Registrable Securities shall only have the right to request in writing three (3) registrations on Form S-3), provided that the Registrable Securities proposed to be included in each such registration statement have a proposed aggregate offering price of at least $500,000 and that no holder shall have a right to request that Registrable Securities be registered on Form S-3 during any calendar year if Registrable Securities of such holder were included in a registration statement on Form S-3 pursuant to a request made by such holder during such calendar year. Each such request by a holder shall: (a) specify the number of Registrable Securities which the holder intends to sell or dispose of, and (b) state the intended method by which the holder intends to sell or dispose of such Registrable Securities. Upon receipt of a request pursuant to this Section 11.4, the Company shall use its best efforts to effect such registration or registrations on Form S-3. 11.5 Company's Obligations in Registration. Whenever the Company is obligated to effect the registration of any Registrable Securities under the Securities Act, as expeditiously as possible the Company will use its best efforts to: (a) prepare and file with the Commission, a registration statement with respect to such Registrable Securities and cause such registration statement to become and remain effective, provided, that the Company shall not be required to keep such registration statement effective, or to prepare and file any amendments or supplements thereto, after the later of (i) the last business day of the ninth month following the date on which such registration statement becomes effective under the Securities Act or such longer period during which the holders of the Registrable Securities registered thereunder shall pay all expenses reasonably incurred to keep such registration statement effective with respect to any of the Registrable Securities so registered or (ii) the date on which all of the Registrable Securities registered pursuant to such registration statement have been sold;

provided, however, that the Company shall not be required to consent to general service of process for all purposes in any jurisdiction where it is not then subject to process, qualify to do business as a foreign corporation where it would not be otherwise required to qualify or submit to liability for state or local taxes where it is not otherwise liable for such taxes;

Each such holder of Registrable Securities will, if requested by the Company prior to the initial filing of any such registration statement, agree in writing, severally but not jointly, to indemnify and hold harmless the Company and each person which controls (within the meaning of the Securities Act) the Company and each other person (including underwriters) who participates in the offering of such 36. <PAGE> Registrable Securities against all losses, claims, damages and liabilities to which the Company or such controlling person or participating person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities arise out of or are based upon any untrue statement of any material fact contained, on the effective date thereof, in any registration statement under which such Registrable Securities were registered under the Securities Act, or in any preliminary prospectus or final prospectus contained therein, or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading, to the extent that any such loss, claim, damage or liability arises out of or is based upon any such statement or omission made in such registration statement, preliminary or final prospectus or amendment or supplement in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such holder of Registrable Securities and specifically stated to be for use in the preparation thereof. Each indemnified party shall cooperate with each indemnifying party in defending any loss, claim, damage, liability or proceeding. (a) Indemnification similar to that specified in the preceding clause of this Section 11.8 (with appropriate modifications) shall be given by the Company and, at the Company's request, each holder of Registrable Securities with respect to any registration or other qualification of securities under any state securities and "blue sky" laws. (b) If the indemnification provided for in clauses (a) and (b) of this Section 11.8 is unavailable or insufficient to hold harmless an indemnified party, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party referred to in clauses (a) and (b) of this Section 11.8 in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and the indemnified party on the other hand in connection with statements or omissions which resulted in losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statements or omissions. The parties agree that it would not be just and equitable if contributions pursuant to this clause were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this clause. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this clause shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any loss, claim, damage, liability or proceeding which is the subject of this clause. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. (c) Each indemnified party shall notify the indemnifying party in writing within ten (10) days after its receipt of notice of the commencement of any action against it in respect of which indemnity may be sought from the indemnifying party pursuant to this 37. <PAGE> Section 11.8. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party, the indemnifying party will be entitled to participate in the defense with counsel satisfactory to such indemnified party. Each indemnified party shall cooperate with each indemnifying party in defending any loss, claim, damage, liability or proceeding. (d) Notwithstanding clauses (a) through (c) of this Section 11.8, the aggregate amount which may be recovered by the Company, controlling persons of the Company or underwriters from each holder of Registrable Securities pursuant to the indemnification and contribution provided for in this Section 11.8 shall be limited to the total net proceeds for which the Registrable Securities were sold by such holder of Registrable Securities. (e) Notwithstanding any of the foregoing, if, in connection with an underwritten public offering of Registrable Securities, the Company, the selling stockholders and the underwriter(s) enter into an underwriting or purchase agreement relating to such offering which contains provisions covering indemnification and contribution among the parties, the indemnification and contribution provisions of this Section 11.8 shall be deemed inoperative for purposes of such offering. 12. Small Business Matters. 12.1 Generally: Certain SBIC Covenants. CIT/VC is a Small Business Investment Company ("SBIC") licensed by the United States Small Business Administration ("SBA"). In order for CIT/VC to acquire and hold the Series B Preferred Stock, it obtained from the Company certain representations and rights as set forth below. As a material inducement to CIT/VC to purchase the Series B Preferred Stock pursuant to the Series B Stock Purchase Agreement, the Company made, and hereby makes the following representations and warranties and agrees to comply with the following covenants: (a) Assuming that CIT/VC's investment in the Company satisfies the requirements of 13 C.F.R. (S)107.865(d), and has complied with the requirements of 13 C.F.R. (S)107.865(e), the Company, together with its "affiliates" (as that term is defined in 13 C.F.R. (S)121.103), is a "small business concern" within the meaning of the Small Business Investment Act of 1958, as amended ("SBIA"), and the regulations thereunder, including Title 13, Code of Federal Regulations, (S)121.301(c). The information set forth in the SBA Forms 480, 652 and Part A of Form 1031 regarding the Company and its affiliates, when it was delivered to CIT/VC at the closing of the sale of the Series B Preferred Stock under the Series B Stock Purchase Agreement, was accurate and complete. (b) The proceeds from the sale of the Series B Preferred Stock were or will be used by the Company to (1) finance working capital and other corporate needs and (2) pay expenses related to the transactions contemplated by the Series B Stock Purchase Agreement. No portion of such proceeds (i) were or will be used to provide capital to a corporation licensed under the SBIA, (ii) were or will be used to acquire farm land, (iii) were or will be used to fund production of a single item or defined limited number of items, generally over a defined production period, and such production constituted or will constitute the majority of the activities of the Company and its Subsidiaries (examples include motion pictures and electric generating 38. <PAGE> plants), or (iv) were or will be used for any purpose contrary to the public interest (including, but not limited to, activities which are in violation of law) or inconsistent with free competitive enterprise, in each case, within the meaning of 13 C.F.R. (S)107.720. (c) Neither the Company's nor any of its Subsidiaries' primary business activity involves, directly or indirectly, providing funds to others, the purchase or discounting of debt obligations, factoring or long-term leasing of equipment with no provision for maintenance or repair, and neither the Company nor any of its Subsidiaries is classified under Major Group 65 (Real Estate) of the SIC Manual. The assets of the business of the Company and its Subsidiaries (the "Business") will not be reduced or consumed, generally without replacement, as the life of the Business progresses, and the nature of the business does not require that a stream of cash payments be made to the Business' financing sources, on a basis associated with the continuing sale of assets (examples of such businesses would include real estate development projects and oil and gas wells). (See 13 C.F.R. 107.720) (d) The proceeds from the sale of the Series B Preferred Stock were not or will not be used substantially for a foreign operation. This subsection (d) does not prohibit such proceeds from being used to acquire foreign materials and equipment or foreign property rights for use or sale in the United States. 12.2 Regulatory Compliance Cooperation. (a) CIT/VC agrees to use commercially reasonable best efforts to avoid the occurrence of a Regulatory Problem. In the event that CIT/VC determines that it has a Regulatory Problem, the Company agrees to use commercially reasonable efforts to take all such actions as are reasonably requested by CIT/VC in order (A) to effectuate and facilitate any transfer by CIT/VC of any Securities of the Company then held by CIT/VC to any Person designated by CIT/VC (subject, however, to compliance with Section 3 of this Agreement), (B) to permit CIT/VC (or any Affiliate of CIT/VC) to exchange all or any portion of the voting Securities of the Company then held by such Person on a share-for-share basis for shares of a class of non-voting Securities of the Company, which non-voting Securities shall be identical in all respects to such voting Securities, except that such new Securities shall be non-voting and shall be convertible into voting Securities on such terms as are requested by CIT/VC in light of regulatory considerations then prevailing, and (C) to continue and preserve the respective allocation of the voting interests with respect to the Company arising out of CIT/VC's ownership of voting Securities of the Company and/or provided for in this Agreement before the transfers and amendments referred to above (including entering into such additional agreements as are requested by CIT/VC to permit any Person(s) designated by CIT/VC to exercise any voting power which is relinquished by CIT/VC upon any exchange of voting Securities for nonvoting Securities of the Company); and the Company shall enter into such additional agreements, adopt such amendments to this Agreement, the Company's Charter and the Company's By-laws and other relevant agreements and taking such additional actions, in each case as are reasonably requested by CIT/VC in order to effectuate the intent of the foregoing. If CIT/VC elects to transfer Securities of the Company to a Regulated Holder in order to avoid a Regulatory Problem, the Company shall enter into such agreements with such Regulated Holder as it may reasonably request in order to assist such Regulated Holder in complying with applicable laws, and regulations to which it is subject. Such agreements may include restrictions on the 39. <PAGE> redemption, repurchase or retirement of Securities of the Company that would result or be reasonably expected to result in such Regulated Holder holding more voting securities or total securities (equity and debt) than it is permitted to hold under such laws and regulations. (b) In the event CIT/VC has the right to acquire any of the Company's Securities from the Company or any other Person (as the result of Sections 3 or 4 of this Agreement or otherwise), at CIT/VC's request the Company will offer to sell to CIT/VC non-voting Securities (or, if the Company is not the proposed seller, will arrange for the exchange of any voting securities for non-voting securities immediately prior to or simultaneous with such sale) on the same terms as would have existed had CIT/VC acquired the Securities so offered and immediately requested their exchange for non-voting Securities pursuant to Section 12.1(a) above. (c) In the event that any Subsidiary of the Company ever offers to sell any of its Securities to CIT/VC, then the Company will cause such Subsidiary to enter into agreements with CIT/VC on substantially similar terms as this Section 12. 12.3 Information Rights and Related Covenants. (a) Promptly after the end of each fiscal year (but in any event prior to February 28 of each year), the Company shall provide to CIT/VC a written assessment, in form and substance satisfactory to CIT/VC, of the economic impact of CIT/VC's financing under the Series B Stock Purchase Agreement, specifying the full-time equivalent jobs created or retained, the impact of the financing on the consolidated revenues and profits of the Business and on taxes paid by the Business and its employees (See 13 C.F.R. 107.630(e)). (b) Upon the request of CIT/VC (or any Affiliate of CIT/VC to whom CIT/VC has Transferred any Securities of the Company), the Company will (A) provide to such Person such financial statements and other information as such Person may from time to time reasonably request for the purpose of assessing the Company's financial condition and (B) furnish to such Person all information reasonably requested by it in order for it to prepare and file SBA Form 468 and any other information reasonably requested or required by the SBA or any successor entity thereto. (c) The Company will at all times comply with the non-discrimination requirements of 13 C.F.R., Parts 112, 113 and 117. 12.4 Remedies. The Company understands that its violation of this Agreement may result in CIT/VC being required by the SBA to sell the Series B Preferred Stock, and such sale may be at depressed prices due to the circumstances and timing of the sale. Therefore, in addition to all other remedies available to CIT/VC for the Company's violation of this Agreement, the Company agrees that CIT/VC shall be entitled to seek specific enforcement or other equitable relief to prevent a violation by the Company of the terms of this Agreement, and the Company waives any requirement that CIT/VC posts any bond as a condition to seeking or obtaining equitable relief. CIT/VC acknowledges and agrees that the remedies available to CIT/VC for the Company's violation of this Agreement shall be limited to whatever equitable relief may be available (such as specific performance, injunctive relief and rescission), damages 40. <PAGE> resulting from CIT/VC being required to divest the Series B Preferred Stock and costs of enforcement. CIT/VC expressly waives any claims for damages resulting from any loss of, or restrictions imposed upon the use of, its SBIC license as a result of the Company's breach of Section 12 of this Agreement. 13. Duration of Agreement. The rights and obligations of each Stockholder, except the rights and obligations contained in Sections 3.1, 3.2, 3.3(c), 10, 11 and 12 hereof, and the covenants hereunder to that Stockholder shall terminate as to each Stockholder upon the closing of the Initial Public Offering by the Company. The obligations contained in Sections 8, 11 and 12 shall survive indefinitely until, by their respective terms, they are no longer applicable. 14. Additional Remedies. In case any one or more of the covenants and/or agreements set forth in this Agreement, the Series A Stock Purchase Agreement, the Series B Stock Purchase Agreement, the Series C Stock Purchase Agreement, the Series D Stock Purchase Agreement and/or the Series E Stock Purchase Agreement shall have been breached by any party hereto, the party or parties entitled to the benefit of such covenants or agreements may proceed to protect and enforce their rights either by proceeding in equity and/or by action at law, including, but not limited to, an action for damages as a result of any such breach; and/or an action for specific performance of any such covenant or agreement contained in this Agreement, the Series A Stock Purchase Agreement, the Series B Stock Purchase Agreement, the Series C Stock Purchase Agreement, the Series D Stock Purchase Agreement and/or the Series E Stock Purchase Agreement and/or a temporary or permanent injunction, in any case without showing any actual damage and without establishing, in the case of an equitable proceeding, that the remedy at law is inadequate. The rights, powers and remedies of the parties under this Agreement are cumulative and not exclusive of any other right, power or remedy which such parties may have under any other agreement or law. No single or partial assertion or exercise of any right, power or remedy of a party hereunder shall preclude any other or further assertion or exercise thereof. Any purported Transfer in violation of the provisions of this Agreement shall be void ab initio. 15. Successors and Assigns; Limitation on Assignment. Except as otherwise expressly provided herein, this Agreement shall bind and inure to the benefit of the Company, each of the Stockholders and the respective successors or heirs and personal representatives and permitted assigns of the Company and each of the Stockholders. Each Stockholder agrees further that, it shall not sell any Shares to any Person not a party to this Agreement unless such Person contemporaneously with such sale executes and delivers to the Company an agreement to be bound by the Stockholders' obligations hereunder, whereupon such Person shall have the same obligations as the Preferred Stockholders under this Agreement. The terms, representations, warranties and covenants contained in Sections 6 and 7 hereof shall be binding upon and shall inure to the benefit of and be enforceable by, the Preferred Stockholders and their respective successors, transferees and assignees, provided, that the rights granted to the Preferred Stockholders by Sections 6.3 and 6.4 may not be transferred or assigned to, and shall not inure to the benefit of, a successor, transferee or assignee of the Preferred Stockholders which is engaged in any business which directly competes with the Company in any line of business engaged in, or planned to be engaged in, by the Company. It is understood and agreed among the parties hereto that this Agreement and the representations, warranties, and covenants made herein are made expressly and solely for the benefit of the other party or parties hereto (or their respective 41. <PAGE> successors or permitted assigns), and that no other person shall be entitled or be deemed to be a third-party beneficiary of any party's rights under this Agreement. 16. Entire Agreement. This Agreement, the Series A Stock Purchase Agreement, the Series B Stock Purchase Agreement, the Series C Stock Purchase Agreement, the Series D Stock Purchase Agreement, the Series E Stock Purchase Agreement, the Charter and the By-Laws of the Company and each of the other documents delivered in connection with the sale by the Company of its Series E Preferred Stock pursuant to the Series E Stock Purchase Agreement contain the entire agreement among the parties with respect to the subject matter hereof and supersede all prior stockholders' agreements, including the Prior Stockholders' Agreement and the Original Stockholders' Agreement, and all other prior and contemporaneous arrangements or understandings with respect thereto. The parties hereto, including the Company and the holders of at least 75% in interest of the outstanding shares of Series A, B, C and D Preferred Stock, voting together as a class, hereby agree that all rights granted and covenants made under the Prior Stockholders' Agreement are hereby waived, released and terminated in their entirety and shall have no further force or effect whatsoever. The rights and covenants provided herein set forth the sole and entire agreement between the parties hereto with respect to the subject matter hereof. 17. Notices. All notices, requests, consents and other communications hereunder to any party shall be deemed to be sufficient if contained in a written instrument delivered in person, duly sent by first class registered or certified mail, postage prepaid, or telecopied or telexed, addressed or telecopied to such party at the address or telecopier number set forth below, or such other address or telecopier number as may hereafter be designated in writing by the addressee in a notice complying as to delivery with the terms of this Section 17; provided, however, that if the Stockholder is foreign, notice shall be sent by both air courier, and telecopied or telexed to such Stockholder: If to the Company: Diversa Corporation 10665 Sorrento Valley Road San Diego, CA 92121 Attention: Chief Executive Officer Telecopier No.: (619) 623-5180 with a copy to: Cooley Godward LLP 4365 Executive Drive, Suite 1100 San Diego, CA 92121 Telecopier: (619) 453-3555 Attention: M.
