                    Shares that is first filed pursuant to Rule 424(b)(7) under
                    the Securities Act, together with the Preliminary Prospectus
                    identified therein that such Term Sheet supplements;

                                       2
<PAGE>
 
hours prior to the First Closing Date (as defined below), with any transfer
taxes payable in connection with the transfer of the Firm Shares to the
Underwriters duly paid, against payment by or on behalf of the Underwriters to
the account of the Company of the aggregate Purchase Price therefor by wire
transfer in immediately available funds. Delivery or registry of and payment for
the Firm Shares shall be made at the offices of Wilson Sonsini Goodrich &
Rosati, P.C., 650 Page Mill Road, Palo Alto, California 94304 at 9:30 A.M., New
York City time, on the fourth full business day following the date of this
Agreement, or at such other place, time or date as the Representatives and the
Company may agree upon. Such time and date of delivery against payment are
herein referred to as the "First Closing Date", and the implementation of all
the actions described in this Section 2(a) is herein referred to as the "First
Closing".

          (b)  For the purpose of covering any over-allotments in connection
with the distribution and sale of the Firm Shares as contemplated by the
Prospectus, the Company and the Selling Stockholders hereby grant to the several
Underwriters an option to purchase, severally and not jointly, the Option
Shares. The purchase price to be paid for any Option Shares shall be the same as
the Purchase Price for the Firm Shares set forth above in paragraph (a) of this
Section 2. The option granted hereby may be exercised as to all or any part of
the Option Shares from time to time within thirty days after the date of the
Prospectus (or, if such 30th day shall be a Saturday or Sunday or a holiday, on
the next business day thereafter when the New York Stock Exchange and the Nasdaq
Stock Market's National Market (the "Nasdaq National Market") are open for
trading). The Underwriters shall not be under any obligation to purchase any of
the Option Shares prior to the exercise of such option. The Representatives may
from time to time exercise the option granted hereby by giving notice in writing
or by telephone (confirmed in writing) to the Company and the Selling
Stockholders setting forth the aggregate number of Option Shares as to which the
several Underwriters are then exercising the option and the date and time for
delivery or registry of and payment for such Option Shares. Any such date of
delivery or registry shall be determined by the Representatives but shall not be
earlier than two business days or later than five business days after such
exercise of the option and, in any event, shall not be earlier than the First
Closing Date. The time and date set forth in such notice, or such other time or
date as the Representatives, the Company and the Selling Stockholders may agree
upon or as the Representatives may determine pursuant to Section 2(a) hereof, is
herein called an "Option Closing Date" with respect to such Option Shares, and
the implementation of all the actions described in this Section 2(b) is herein
referred to as the "Option Closing". As used in this Agreement, the term
"Closing Date" means either the First Closing Date or any Option Closing Date,
as applicable, and the term "Closing" means either the First Closing or any
Option Closing, as applicable. If the option is exercised as to all or any
portion of the Option Shares, then either one or more certificates in definitive
form for such Option Shares shall be delivered or, if such Option Shares are to
be held through DTC, such Option Shares shall be registered and credited, on the
related Option Closing Date in the same manner, and upon the same terms and
conditions, set forth in paragraph (a) of this Section 2, except that reference
therein to the Firm Shares and the First Closing Date shall be deemed, for
purposes of this paragraph (b), to refer to such Option Shares and Option
Closing Date, respectively. Upon exercise of the option as provided herein, the
Company and the Selling Stockholders shall become obligated to sell to each of
the several Underwriters, and, on the basis of the representations, warranties,
agreements and covenants herein contained and subject to the terms and
conditions herein set forth, each of the Underwriters (severally and not
jointly) shall become obligated to purchase from the Company and the Selling
Stockholders, the same percentage of the total number

                                       3
<PAGE>
 
of the Option Shares as to which the several Underwriters are then exercising
the option as such Underwriter is obligated to purchase of the aggregate number
of Firm Shares, as adjusted by the Representatives in such manner as they deem
advisable to avoid fractional shares. In the event that the option is exercised
in part, the number of Option Shares to be sold by each of the Selling
Stockholders shall be, as nearly as practicable, in the same proportion to each
other as are the number of Option Shares to be sold by each Selling Stockholder
listed opposite their names on Schedule 2 hereto.

               (c)  The Company and the Selling Stockholders hereby acknowledge
that the payment of monies pursuant to Section 2(a) hereof (a "Payment") by or
on behalf of the Underwriters of the aggregate Purchase Price for any Shares
does not constitute closing of a purchase and sale of the Shares. Only execution
and delivery, by facsimile or otherwise, of a receipt for Shares by the
Underwriters indicates completion of the closing of a purchase of the Shares
from the Company and the Selling Stockholders. Furthermore, in the event that
the Underwriters make a Payment to the Company and the Selling Stockholders
prior to the completion of the closing of a purchase of Shares, the Company and
the Selling Stockholders hereby acknowledge that until the Underwriters execute
and deliver such receipt for the Shares, the Company and the Selling
Stockholders will not be entitled to the Payment and shall return the Payment to
the Underwriters as soon as practicable (by wire transfer of same-day funds)
upon demand. In the event that the closing of a purchase of Shares is not
completed and the Payment is not returned by the Company and the Selling
Stockholders to the Underwriters on the same day the Payment was received by the
Company and the Selling Stockholders, the Company and the Selling Stockholders
agree to pay to the Underwriters in respect of each day the Payment is not
returned by them, in same-day funds, interest on the amount of such Payment in
an amount representing the Underwriters' cost of financing as reasonably
determined by the Representatives, pro rata in proportion to the percentage of
                                   --- ----
such Payment received by each.

               (d)  It is understood that any of you, individually and not as
one of the Representatives, may (but shall not be obligated to) make Payment on
behalf of any Underwriter or Underwriters for any of the Shares to be purchased
by such Underwriter or Underwriters. No such Payment shall relieve such
Underwriter or Underwriters from any of its or their obligations hereunder.

Section 3.     Covenants.
               --------- 
               (a)  The Company covenants and agrees with the several

                    promptly as possible.  If required, the Company will file

                    thereof and any amendment or supplement thereto with the
                    Commission in the manner and within the time period required
                    by Rules 434 and 424(b) under the Securities Act.  During
                    any time when a prospectus relating to the Shares is
                    required to be

                                       4

                    referred to in the second sentence of Section 5(a)(i)
                    hereof) or any Rule 462(b) Registration Statement unless the
                    Representatives previously have been advised of, and
                    furnished with a copy within a reasonable period of time
                    prior to, the proposed filing and the Representatives shall
                    have given their consent to such filing.  The Company will
                    prepare and file with the Commission, in accordance with the
                    rules and regulations of the Commission, promptly upon

                    amendment thereto has been filed or declared effective or
                    the Prospectus or Term Sheet or any amendment or supplement

                    of the Original Registration Statement and each amendment

                    confirming orders that are expected to settle on the First
                    Closing Date.

                    (z)  advise the Representatives, promptly after receiving
                    notice or obtaining knowledge thereof, of (I) the issuance
                    by the Commission of any stop order suspending the

                    supplementing the Prospectus or for additional information.
                    The Company will use all reasonable efforts to prevent the
                    issuance of any such stop order and, if any such stop order
                    is issued, to obtain the withdrawal thereof as promptly as

             U.S. jurisdictions, and the Company shall maintain such
             qualifications in effect for so long as may be necessary in order
             to complete the placement of the Shares; provided, however, that
             the Company shall not be obliged to file any general consent to
             service of process or to qualify as a foreign corporation or as a
             securities dealer in any jurisdiction or to subject itself to

             it is not otherwise so subject.

             (iii)  If, at any time prior to the final date when a prospectus
             to the Shares is required to be delivered under the Securities Act,
             any event occurs as a result of which the Prospectus, as then
             amended or supplemented, would include any untrue statement of a
             material fact or omit to state any material fact necessary in order
             to make the statements therein, in the light of the circumstances
             under which they were made, not misleading, or if for any other
             reason it shall be necessary at any time to amend the Registration
             Statement or amend or supplement the Prospectus to comply with the
             Securities Act or the rules or regulations of the Commission

             amendment to the Registration Statement or amendment or supplement
             to the Prospectus which will correct such statement or omission or
             effect such compliance; and (y) supply any amended Registration
             Statement or amended or supplemented Prospectus to the Underwriters
             in such quantities as the Underwriters may reasonably request.

             (iv)   The Company will make generally available to its
             securityholders and to the Representatives as soon as practicable
             an earnings statement that satisfies the provisions of Section

             Representatives' sole judgment the market price of the Shares has
             been or is likely to be materially affected (regardless of whether
             such rumor, publication or event necessitates a supplement to or
             amendment of the Prospectus), the Company will, after notice from
             the Representatives advising the Company to the effect set forth
             above, forthwith prepare, consult with the Representatives

        (b)  Each Selling Stockholder agrees that:

             (i)    It will not, and no person acting on behalf of such Selling
             Stockholder will, directly or indirectly, (x) take any action

             itself, without the prior written consent of the Representatives on
             behalf of the

               ------------------------------   
           
               (a)  As a condition of the obligation of the Underwriters to
underwrite and purchase the Shares, the Company and, to the best of their
knowledge after careful review of this Agreement, the Registration Statement and
the Prospectus, the Selling Stockholders represent and warrant to, and agree
with, each of the several Underwriters as follows:

               Registration Statement and Prospectus

                    (i)  The Original Registration Statement, including the
               Preliminary Prospectus, has been filed by the Company with the
               Commission under the Securities Act, and one or more amendments
               to such Registration Statement may have been so filed. After the
               execution of this Agreement, the Company will file with the
               Commission either (x) if such Registration Statement, as it may
               have been amended, has been declared by the Commission to be
               effective under the Securities Act, either (I) if the Company
               relies on Rule 434 under the Securities Act, a Term Sheet
               relating to the Shares that shall identify the Preliminary
               Prospectus that it supplements containing such information as is
               required or permitted by Rules 434, 430A and 424(b) under the
               Securities Act or (II) if the Company does not rely on Rule 434
               under the Securities Act, a prospectus in the form most recently
               included in an amendment to such Registration Statement (or, if
               no such amendment shall have been filed, in such Registration
               Statement), with such changes or insertions as are required by
               Rule 430A under the Securities Act or permitted by Rule 424(b)
               under the Securities Act, and in the case of either clause (I) or
               (II) of this sentence, as have been provided to and approved by
               the Representatives prior to the execution of this Agreement, or
               (y) if such Registration Statement, as it may have been amended,
               has not been declared by the Commission to be effective under the
               Securities Act, an amendment to such Registration Statement,
               including a form of prospectus, a copy of which amendment has
               been furnished to and approved by the Representatives prior to
               the execution of this Agreement. The Company may also file a Rule
               462(b) Registration Statement with the Commission for the purpose
               of registering certain 

                                      10

               additional Shares, which registration shall be effective upon
               filing with the Commission.

                    (ii)  The Commission has not issued any order preventing or
               suspending the use of any Preliminary Prospectus. When any
               Preliminary Prospectus was filed with the Commission, it (x)
               contained all statements required to be stated therein in
               accordance with, and complied in all material respects with the
               requirements of, the Securities Act and the rules and regulations
               of the Commission thereunder and (y) did not include any untrue
               statement of a material fact or omit to state any material fact
               necessary in order to make the statements therein, in the light
               of the circumstances under which they were made, not misleading.
               When the Registration Statement or any amendment thereto was or
               is declared effective, it (I) contained or will contain all
               statements required to be stated therein in accordance with, and
               complied or will comply in all material respects with the
               requirements of, the Securities Act and the rules and regulations
               of the Commission thereunder and (II) did not or will not contain
               any untrue statement of a material fact or omit to state any
               material fact required to be stated therein or necessary to make
               the statements therein not misleading. When the Prospectus or any
               Term Sheet that is a part thereof or any amendment or supplement
               to the Prospectus is filed with the Commission pursuant to Rule
               424(b) (or, if the Prospectus or such amendment or supplement is
               not required to be so filed, when the Registration Statement or
               the amendment thereto containing the Prospectus or such amendment
               or supplement to the Prospectus was or is declared effective) and
               on the Closing Date, the Prospectus, as amended or supplemented
               at any such time, (A) contained or will contain all statements
               required to be stated therein in accordance with, and complied or
               will comply in all material respects with the requirements of,
               the Securities Act and the rules and regulations of the
               Commission thereunder and (B) did not or will not include any
               untrue statement of a material fact or omit to state any material
               fact necessary in order to make the statements therein, in the
               light of the circumstances under which they were made, not
               misleading. The foregoing provisions of this paragraph (ii) do
               not apply to statements or omissions made in any Preliminary
               Prospectus, the Registration Statement or any amendment thereto
               or the Prospectus or any amendment or supplement thereto in
               reliance upon and in conformity with written information
               furnished to the Company by any Underwriter through the
               Representatives specifically for use therein.

                    (iii) If the Company has elected to rely on Rule 462(b) and
               the Rule 462(b) Registration Statement is not effective, (x) the
               Company will file a Rule 462(b) Registration Statement in
               compliance with, and that is effective upon filing pursuant to,
               Rule 462(b) and (y) the Company has given irrevocable
               instructions for transmission of the applicable filing fee in
               connection with the filing of the Rule 462(b) Registration
               Statement, in compliance with Rule 111 under the Securities Act,
               or the Commission has received payment of such filing fee.

                    (iv)  If the Company has elected to rely on Rule 434 under
               the Securities Act, the Prospectus is not "materially different",
               as such term is used in Rule 434,

                                      11
<PAGE>
 
               from the prospectus included in the Registration Statement at the
               time of its effectiveness or an effective post-effective
               amendment thereto (including such information that is permitted
               to be omitted pursuant to Rule 430A under the Securities Act).

                    (v)    The Company has not distributed and, prior to the
               later of (x) any Closing Date and (y) the completion of the
               distribution of the Shares, will not distribute any offering
               material in connection with the Offering other than the
               Registration Statement or any amendment thereto, any Preliminary
               Prospectus or the Prospectus or any amendment or supplement
               thereto.

                    (vi)   Subsequent to the respective dates as of which
               information is given in the Registration Statement and the
               Prospectus, (x) the Company has not incurred any material
               liability or obligation, direct or contingent, nor entered into
               any material transaction not in the ordinary course of business;
               (y) the Company has not purchased any of its outstanding capital
               stock, nor declared, paid or otherwise made any dividend or
               distribution of any kind on its capital stock; and (z) there has
               not been any material change in the capital stock, short-term or
               long-term debt of the Company, except in each case as described
               in or contemplated by the Prospectus.

               capitalization as set forth in the Prospectus, and the Company
               has no subsidiaries. All of the issued shares of capital stock of
               the Company have been duly authorized and validly issued and are

               Shares have been duly authorized by all necessary corporate
               action of the Company and, after payment therefor in accordance
               herewith, will be validly issued, fully paid and nonassessable at
               the Closing Date. No holders of outstanding shares of capital
               stock of the Company are entitled as such to any preemptive or
               other rights to subscribe for any of the Shares, and no holder of
               securities of the Company has any right which has not been fully
               exercised or waived to require the Company to register the offer
               or sale of any securities owned by such holder under the
               Securities Act in the Offering contemplated by this Agreement.

                    (viii) Except as disclosed in the Prospectus, there are no

               convertible into or exchangeable for any capital stock of the
               Company, (y) warrants, rights or options to subscribe for or
               purchase from the Company any such capital stock or any such
               convertible or exchangeable securities or obligations, or (z)
               obligations of the Company to issue any shares of capital stock,
               any such convertible or exchangeable securities or obligations,
               or any such warrants, rights or options.

               other equity securities of any corporation or have any equity
               interest in any firm, partnership, association or other entity,
               except as described in or contemplated by the Prospectus.

          contemplated by the Prospectus.

          Taxes

               (xxiv)   The Company has filed all foreign, federal, state and
          local tax returns that are required to be filed or has requested
          extensions of the time for filing thereof (except in any case in which

          the Company) and has paid all taxes required to be paid by it and any
          other assessment, fine or penalty levied against it, to the extent
          that any of the foregoing is due and payable, except for any such

          Insurance

               (xxv)    The Company is insured by insurers of recognized

          the Prospectus; the Company has not been refused any insurance
          coverage sought or applied for; and the Company has no reason to
          believe that it will not be able to renew its existing insurance
          coverage as and when such coverage expires or to obtain similar
          coverage from similar insurers as may be necessary to continue its
          business at a cost that would not materially and adversely affect the
          condition (financial or otherwise), earnings, properties, business
          affairs or business prospects, net worth or results of operations of
          the Company, except as described in or contemplated by the Prospectus.

          Pension and Labor

               (xxvi)   The Company is in compliance in all material respects

          (as defined in ERISA) has occurred with respect to any "pension plan"
          (as defined in ERISA) for which the Company would have any liability;
          the Company has not incurred and does not expect to incur liability

          Internal Revenue Code of 1986, as amended, including the regulations
          and published interpretations thereunder (the "Code"); and each
          "pension plan" for which the Company would have any liability that is
          intended to be qualified under Section 401(a) of the Code is so
          qualified in all material respects and nothing has occurred, whether
          by action or by failure to act, which would cause the loss of such
          qualification.

          exists or is threatened or imminent that could have a materially

          compliance with all terms and conditions of any such permit, license
          or approval, except any such violation of law or regulation, failure
          to receive required permits, licenses or other approvals or failure to
          comply with the terms and conditions of such permits, licenses or

          in, or constitute a development involving a prospective materially
          adverse effect on or change in, the condition (financial or

          prospects, net worth or results of operations of the Company, except

Underwriters that:

               (i)    Such Selling Stockholder has full power to enter into this
          Agreement and to sell, assign, transfer and deliver to the
          Underwriters the Shares to be sold by such Selling Stockholder
          hereunder in accordance with the terms of this Agreement; and this
          Agreement has been duly executed and delivered by such Selling
          Stockholder.

               (ii)   Such Selling Stockholder has duly executed and delivered a
          power of attorney and custody agreement (with respect to such Selling
          Stockholder, the "Power-of-Attorney" and the "Custody Agreement",
          respectively), each in the form heretofore delivered to the
          Representatives, appointing Mark R. Templeton and Robert D. Selvi as
          such Selling Stockholder's attorneys-in-fact (the "Attorney-in-Fact")
          with authority to execute, deliver and perform this Agreement on
          behalf of such Selling Stockholder and appointing First National Bank
          of Boston, as custodian thereunder (the "Custodian"). Certificates in
          negotiable form, endorsed in blank or accompanied by blank stock
          powers duly executed, with signatures appropriately guaranteed,
          representing the Shares to be sold by such Selling Stockholder
          hereunder have been deposited with the Custodian pursuant to the
          Custody Agreement for the purpose of delivery pursuant to this
          Agreement. Such Selling Stockholder has full power to enter into the
          Custody Agreement and the Power-of-Attorney and to perform its
          obligations under the Custody Agreement. The Custody Agreement and the
          Power-of-Attorney have been duly executed and delivered by such
          Selling Stockholder and, assuming due authorization, execution and
          delivery by the Custodian, are the legal, valid, binding and
          enforceable instruments of such Selling Stockholder. Such Selling
          Stockholder agrees that each of the Shares represented by the
          certificates on deposit with the Custodian is subject to the interests
          of the Underwriters hereunder, that the arrangements made for such
          custody, the appointment of the Attorney-in-Fact and the right, power
          and authority of the Attorney-in-Fact to execute and deliver this
          Agreement, to agree on the price at which the Shares (including such
          Selling Stockholder's Shares) are to be sold to the Underwriters, and
          to carry out the terms of this Agreement, are to that extent
          irrevocable and that the obligations of such Selling Stockholder
          hereunder shall not be terminated, except as provided in this
          Agreement or the Custody Agreement, by any act of such Selling
          Stockholder, by operation of law or otherwise, whether in the case of
          any individual Selling Stockholder by the death or incapacity of such
          Selling 

                                      18

          Stockholder, in the case of a trust or estate by the death of the
          trustee or trustees or the executor or executors or the termination of
          such trust or estate, or in the case of a corporate or partnership
          Selling Stockholder by its liquidation or dissolution or by the
          occurrence of any other event. If any individual Selling Stockholder,
          trustee or executor should die or become incapacitated or any such
          trust should be terminated, or if any corporate or partnership Selling
          Stockholder shall liquidate or dissolve, or if any other event should
          occur, before the delivery of such Shares hereunder, the certificates
          for such Shares deposited with the Custodian shall be delivered by the
          Custodian in accordance with the respective terms and conditions of
          this Agreement as if such death, incapacity, termination, liquidation
          or dissolution or other event had not occurred, regardless of whether
          or not the Custodian or the Attorney-in-Fact shall have received
          notice thereof.

               (iii)  Such Selling Stockholder is the lawful owner of the Shares
          to be sold by such Selling Stockholder hereunder and upon sale and
          delivery of, and payment for, such Shares, as provided herein, such
          Selling Stockholder will convey good and marketable title to such
          Shares, free and clear of any security interests, liens, encumbrances,
          equities, claims or other defects.

               (iv)   Neither such Selling Stockholder nor any person acting on
          behalf of it has, directly or indirectly, (x) taken any action
          designed to cause or to result in, or that has constituted or which
          might reasonably be expected to constitute, the stabilization or
          manipulation of the price of any security of the Company to facilitate
          the sale or resale of the Shares or (y) since the filing of the
          Original Registration Statement (I) sold, bid for, purchased, or paid
          anyone any compensation for soliciting purchases of, the Shares or
          (II) paid or agreed to pay to any person any compensation for
          soliciting another to purchase any other securities of the Company
          (except for the sale of Shares by the Selling Stockholders under this
          Agreement).

               (v)    Such Selling Stockholder has carefully reviewed this
          Agreement, the Prospectus and the Registration Statement, and the
          information regarding such Selling Stockholder set forth therein under
          the caption "Principal Stockholders" is complete and accurate. All
          information furnished by or on behalf of such Selling Stockholder for
          use in the Registration Statement is, and on each Closing Date will
          be, true, correct, and complete, and does not, and on such Closing
          Date will not, contain any untrue statement of a material fact or omit
          to state any material fact necessary to make such information not
          misleading, and all information furnished in writing by or on behalf
          of such Selling Stockholder for use in the Prospectus is, and on such
          Closing Date will be, true, correct, and complete, and does not, and
          on such Closing Date will not, contain any untrue statement of a
          material fact or omit to state any material fact necessary to make
          such information not misleading in the light of the circumstances
          under which they were made.

               (vi)   The sale by such Selling Stockholder of Shares pursuant
          hereto is not prompted by any adverse information concerning the
          Company that is not set forth in the Registration Statement or the
          Prospectus.

               (vii)  The sale of the Shares to the Underwriters by such Selling
          Stockholder pursuant to this Agreement, the compliance by such Selling
          Stockholder with the other provisions of this Agreement, the Custody
          Agreement and the consummation of the other transactions herein
          contemplated do not (i) require the consent, approval, authorization,
          registration or qualification of or with any governmental authority,
          except such as have been obtained or made or such as may be required
          by state securities or Blue Sky laws of the various states of the
          United States of America or such other U.S. jurisdictions or by the
          NASD and, if the Registration Statement is not effective under the
          Securities Act as of the time of execution hereof, such as may be
          required (and shall be obtained as provided in this Agreement) under
          the Securities Act, or (ii) conflict with or result in a breach or
          violation of any of the terms and provisions of, or constitute a
          default under any indenture, mortgage, deed of trust, lease or other
          agreement or instrument to which such Selling Stockholder is a party
          or by which such Selling Stockholder or any of such Selling
          Stockholder's properties are bound, or any statute or any judgment,
          decree, order, rule or regulation of any court or other governmental
          authority or any arbitrator applicable to such Selling Stockholder.

               (viii) Such Selling Shareholder has not distributed and, prior to
          the later of (x) any Closing Date and (y) the completion of the
          distribution of the Shares, will not distribute any offering material
          in connection with the offering other than the Registration Statement
          or any amendment thereto, any Preliminary Prospectus or the Prospectus
          or any amendment or supplement thereto.

          (c)  The above representations and warranties shall be deemed to be
repeated at each Closing, and all references therein to the Shares and the
Closing Date shall be deemed to refer to the Firm Shares or the Option Shares
and the First Closing Date or the applicable Option Closing Date, each as
applicable.

Section 6. Indemnity.
           --------- 

           (a) The Company agrees to indemnify and hold harmless each
Underwriter and each person, if any, who controls any Underwriter within the
meaning of Section 15 of the Securities Act or Section 20 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), against any and all
losses, claims, damages or liabilities, joint or several, to which such
Underwriter or such controlling person may become subject under the Securities
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon:

               (i)  any untrue statement or alleged untrue statement made by the
               Company in Section 5 hereof,

               (ii) any untrue statement or alleged untrue statement of any
               material fact contained in the Registration Statement or any
               amendment thereto, any Preliminary Prospectus or the Prospectus
               or any amendment or supplement thereto, or

                                      20
<PAGE>
 
               (iii) the omission or alleged omission to state in the
               Registration Statement or any amendment thereto, any Preliminary
               Prospectus or the Prospectus or any amendment or supplement
               thereto a material fact required to be stated therein or
               necessary to make the statements therein not misleading,

and will reimburse, as incurred, each Underwriter and each such controlling
person for any legal or other costs or expenses reasonably incurred by such
Underwriter or such controlling person in connection with investigating,
defending against or appearing as a third-party witness in connection with any
such loss, claim, damage, liability or action; provided, however, that the
Company will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any untrue statement
or alleged untrue statement or omission or alleged omission made in the
Registration Statement or any amendment thereto, any Preliminary Prospectus, the
Prospectus or any amendment or supplement thereto in reliance upon and in
conformity with written information furnished to the Company by such Underwriter
through the Representatives specifically for use therein; and provided, further,
that the Company will not be liable to any Underwriter or any person controlling
such Underwriter with respect to any such untrue statement, alleged untrue
statement, omission or alleged omission made in any Preliminary Prospectus that
is corrected in the Prospectus or any amendment or supplement thereto if the
person asserting any such loss, claim, damage or liability purchased Shares from
such Underwriter but was not sent or given a copy of the Prospectus, as amended
or supplemented, in any case where such delivery of the Prospectus, as amended
or supplemented, was required by the Securities Act, unless such failure to
deliver the Prospectus, as amended or supplemented, was a result of
noncompliance by the Company with Section 3 hereof. The indemnity provided for
in this Section 6 shall be in addition to any liability which the Company may
otherwise have. The Company will not, without the prior written consent of the
Representatives, settle or compromise or consent to the entry of any judgment in
any pending or threatened claim, action, suit or proceeding in respect of which
indemnification may be sought hereunder (whether or not any such Representatives
or any person who controls any such Representatives is a party to such claim,
action, suit or proceeding), unless such settlement, compromise or consent
includes an unconditional release of all of the Underwriters and such
controlling persons from all liability arising out of such claim, action, suit
or proceeding.

          (b) Each of the Selling Stockholders severally and not jointly agrees
to indemnify and hold harmless each Underwriter and each person, if any, who
controls any Underwriter within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act, against any and all losses, claims, damages
or liabilities, joint or several, to which such Underwriter or such controlling
person may become subject under the Securities Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement made by
such Selling Stockholder in Section 5 hereof,

                                      21
<PAGE>
 
and will reimburse, as incurred, each Underwriter and each such controlling
person for any legal or other costs or expenses reasonably incurred by such
Underwriter or such controlling person in connection with investigating,
defending against or appearing as a third-party witness in connection with any
such loss, claim, damage, liability or action; provided, however, that such
Selling Stockholder will not be liable in any such case to the extent that any
such loss, claim, damage or liability arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
the Registration Statement or any amendment thereto, any Preliminary Prospectus,
the Prospectus or any amendment or supplement thereto in reliance upon and in
conformity with written information furnished to the Company by such Underwriter
through the Representatives specifically for use therein. Notwithstanding any
other provision of this paragraph (b), no Selling Stockholder shall be liable
for indemnification hereunder in an aggregate amount exceeding the net proceeds
(before deducting expenses) received by such Selling Stockholder in respect of
the Shares sold by such Selling Stockholder to the Underwriters pursuant to this
Agreement. The indemnity provided for in this Section 6 shall be in addition to
any liability which the Selling Stockholders may otherwise have. The Selling
Stockholders will not, without the prior written consent of the Representatives,
settle or compromise or consent to the entry of any judgment in any pending or
threatened claim, action, suit or proceeding in respect of which indemnification
may be sought hereunder (whether or not any such Representatives or any person
who controls any such Representatives is a party to such claim, action, suit or
proceeding), unless such settlement, compromise or consent includes an
unconditional release of all of the Underwriters and such controlling persons
from all liability arising out of such claim, action, suit or proceeding.

          (c)  Each Underwriter, severally and not jointly, agrees to indemnify
and hold harmless the Company, each of its directors, each of its officers who
signed the Registration Statement, each Selling Stockholder and each person, if
any, who controls the Company or such Selling Stockholder within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act against any
losses, claims, damages or liabilities to which the Company or any such director
or officer of the Company, such Selling Stockholder or any such controlling
person of the Company or such Selling Stockholder may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in the Registration Statement or any amendment thereto, any Preliminary
Prospectus or the Prospectus or any amendment or supplement thereto or (ii) the
omission or the alleged omission to state in the Registration Statement or any
amendment thereto, any Preliminary Prospectus or the Prospectus or any amendment
or supplement thereto a material fact required to be stated therein or necessary
to make the statements therein not misleading, in each case to the extent, but
only to the extent, that such untrue statement or alleged untrue statement or
omission or alleged omission was made in reliance upon and in conformity with
written information furnished to the Company by such Underwriter through the
Representatives specifically for use therein, and, subject to the limitation set
forth immediately preceding this clause, will reimburse, as incurred, any legal
or other expenses 

                                      22
<PAGE>
 
reasonably incurred by the Company or any such director, officer or controlling
person or such Selling Stockholder or controlling person of such Selling
Stockholder in connection with investigating, defending against or appearing as
a third-party witness in connection with any such loss, claim, damage, liability
or any action in respect thereof. The indemnity provided in this Section 6 will
be in addition to any liability which any Underwriter may otherwise have. The 
Underwriters will not, without the prior written consent of the Company, settle 
or compromise or consent to the entry of any judgment in any pending or
threatened claim, action, suit or proceeding in respect of which indemnification
may be sought hereunder (whether or not the Company or any person who controls
the Company is a party to such claim, action, suit or proceeding), unless such
settlement, compromise or consent includes an unconditional release of all of
the Company and such controlling persons from all liability arising out of such
claim, action, suit or proceeding. The remedies provided for in this Section 6
are not exclusive and shall not limit any rights or remedies which may otherwise
be available to any indemnified party at law or in equity.

          (d)  In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to paragraph (a), (b) or (c) of this Section 6, such person (for
purposes of this paragraph (d), the "indemnified party") shall, promptly after
receipt by such party of notice of the commencement of such action, notify the
person against whom such indemnity may be sought (for purposes of this paragraph
(d), the "indemnifying party"), but the omission so to notify the indemnifying
party will not relieve it from any liability which it may have to any
indemnified party otherwise than under this Section 6. In case any such action
is brought against any indemnified party, and it notifies the indemnifying party
of the commencement thereof, the indemnifying party will be entitled to
participate therein and, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party; provided, however, that if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be one or more legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnifying party shall not have the right to
direct the defense of such action on behalf of such indemnified party or parties
and such indemnified party or parties shall have the right to select separate
counsel to defend such action on behalf of such indemnified party or parties.
After notice from the indemnifying party to such indemnified party of its
election so to assume the defense of any such action and approval by such
indemnified party of counsel appointed to defend such action, the indemnifying
party will not be liable to such indemnified party under this Section 6 for any
legal or other expenses, other than reasonable costs of investigation,
subsequently incurred by such indemnified party in connection with the defense
thereof, unless (i) the indemnified party shall have employed separate counsel
in accordance with the proviso to the next preceding sentence (it being
understood, however, that in connection with such action the indemnifying party
shall not be liable for the expenses of more than one separate counsel (in
addition to local counsel) in any one action or separate but substantially
similar actions in the same jurisdiction arising out of the same general
allegations or circumstances, designated in writing by the Representatives in
the case of paragraph (a) or (b) of this Section 6, representing the indemnified
parties under such paragraph (a) or (b) who are parties to such action or
actions), or (ii) the indemnifying party does not promptly retain counsel
satisfactory to the indemnified party, or (iii) the indemnifying party has
authorized the employment of counsel for the indemnified party at the expense of
the indemnifying party. All fees and expenses reimbursed pursuant to this
paragraph (d) shall be reimbursed as they are incurred. After such notice from
the indemnifying party to such indemnified party, the indemnifying party will
not be liable for the costs and expenses of any settlement of such action
effected by such indemnified party without the consent of the indemnifying
party.

                                      23
<PAGE>
 
          (e)  In circumstances in which the indemnity agreement provided for in
the preceding paragraphs of this Section 6 is unavailable or insufficient, for
any reason, to hold harmless an indemnified party in respect of any losses,
claims, damages or liabilities (or actions in respect thereof), each
indemnifying party, in order to provide for just and equitable contribution,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect (i) the relative
benefits received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the Offering or (ii) if the allocation
provided by the foregoing clause (i) is not permitted by applicable law, not
only such relative benefits but also the relative fault of the indemnifying
party or parties on the one hand and the indemnified party on the other in
connection with the statements or omissions or alleged statements or omissions
that resulted in such losses, claims, damages or liabilities (or actions in
respect thereof), as well as any other relevant equitable considerations. The
relative benefits received by the Company and the Selling Stockholders on the
one hand and the Underwriters on the other shall be deemed to be in the same
proportion as the total proceeds from the Offering (before deducting expenses)
received by the Company and the Selling Stockholders bear to the total
underwriting discounts and commissions received by the Underwriters. The
relative fault of the parties 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 Company, the Selling Stockholders or the Underwriters, the
parties' relative intents, knowledge, access to information and opportunity to
correct or prevent such statement or omission, and any other equitable
considerations appropriate in the circumstances. The Company, the Selling
Stockholders and the Underwriters agree that it would not be equitable if the
amount of such contribution were determined by pro rata or per capita allocation
(even if the Underwriters were treated as one entity for such purpose) or by any
other method of allocation that does not take into account the equitable
considerations referred to above in this paragraph (e). Notwithstanding any
other provision of this paragraph (e), no Underwriter shall be obligated to make
contributions hereunder that in the aggregate exceed the total public offering
price of the Shares purchased by such Underwriter under this Agreement, less the
aggregate amount of any damages that such Underwriter has otherwise been
required to pay in respect of the same or any substantially similar claim, and
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. The Underwriters'
obligations to contribute hereunder are several in proportion to their
respective underwriting obligations and not joint, and contributions among
Underwriters shall be governed by the provisions of the Deutsche Morgan Grenfell
Inc. Master Agreement Among Underwriters. For purposes of this paragraph (e),
each person, if any, who controls an Underwriter within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act shall have the same
rights to contribution as such Underwriter, and each director of the Company,
each officer of the Company who signed the Registration Statement and each
person, if any, who controls the Company or any Selling Stockholder within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act,
shall have the same rights to contribution as the Company or such Selling
Stockholder, as the case may be.

Section 7.  Conditions Precedent.   The obligations of the several Underwriters
            --------------------
to purchase and pay for the Shares shall be subject, in the Representatives'
sole discretion, to the accuracy of the representations and warranties of the

amendment shall have been declared effective not later than 6:00 P.M. New York
City time on the date of determination of the public offering price, if such
determination occurred at or prior to 4:30 P.M. New York City time on such date,
or 12:00 Noon New York City time on the business day following the day on which
the public offering price was determined, if such determination occurred after
4:30 P.M. New York City time on such date, and (ii) if the Company has elected
to rely upon Rule 462(b), the Rule 462(b) Registration Statement shall have been
declared effective not later than the time confirmations are sent or given as
specified by Rule 462(b)(2), or such later time and date as shall have been
consented to by the Representatives; if required, the Prospectus or any Term
Sheet that constitutes a part thereof and any amendment or supplement thereto
shall have been filed with the Commission in the manner and within the time
period required by Rules 434 and 424(b) under the Securities Act; no stop order
suspending the effectiveness of the Registration Statement or any amendment
thereto shall have been issued, and no proceedings for that purpose shall have
been instituted or threatened or, to the knowledge of the Company or the
Representatives, shall be contemplated by the Commission; and the Company shall
have complied with any request of the Commission for additional information (to

          (b)  The Representatives shall have received a legal opinion from
Wilson Sonsini Goodrich & Rosati, Professional Corporation, counsel for the
Company, dated the Closing Date, to the effect that:

               (i)   the Registration Statement is effective under the
               Securities Act; any required filing of the Prospectus, or any
               Term Sheet that constitutes a part thereof, pursuant to Rules 434
               and 424(b) has been made in the manner and within the time period
               required by Rules 434 and 424(b); and no stop order suspending
               the effectiveness of the Registration Statement or any amendment
               thereto has been issued and, to the best knowledge of such
               counsel, no proceedings for that purpose are pending or
               threatened by the Commission;

               (ii)  the Original Registration Statement and each amendment
               thereto, any Rule 462(b) Registration Statement and the
               Prospectus (in each case, other than the financial statements,
               including the notes thereto, schedule and other financial
               information contained therein, as to which such counsel need
               express no opinion) comply as to form in all material respects
               with the applicable requirements of the Securities Act and the
               rules and regulations of the Commission thereunder;

               (iii) such counsel has no reason to believe that (in each case,
               other than the financial statements, including the notes thereto,
               schedule and other 

                                      25
<PAGE>
 
               financial information contained therein, as to which such counsel
               need express no opinion) (x) the Registration Statement, as of
               its effective date, contained any untrue statement of a material
               fact or omitted to state a material fact required to be stated
               therein or necessary to make the statements therein not
               misleading or (y) the Prospectus, as of its date or the date of
               such opinion, included or includes any untrue statement of a
               material fact or omitted or omits to state a material fact
               necessary in order to make the statements therein, in the light
               of the circumstances under which they were made, not misleading.

               (iv)  if the Company elects to rely on Rule 434 under the
               Securities Act, the Prospectus is not "materially different", as
               such term is used in Rule 434, from the prospectus included in
               the Registration Statement at the time of its effectiveness or an
               effective post-effective amendment thereto (including such
               information that is permitted to be omitted pursuant to Rule 430A
               under the Securities Act);

               (v)   the Company has an authorized, issued and outstanding
               capitalization as set forth in the Prospectus as of the dates
               stated therein; all of the issued shares of capital stock of the
               Company have been duly authorized and validly issued and are
               fully paid and nonassessable, have been issued in compliance with
               all applicable federal and state securities laws and were not
               issued in violation of or subject to any preemptive rights or
               other rights to subscribe for or purchase securities; the Shares
               have been duly authorized by all necessary corporate action of
               the Company and, when issued and delivered to and paid for by the
               Underwriters pursuant to this Agreement, will be validly issued,
               fully paid and nonassessable; no holders of outstanding shares of
               capital stock of the Company are entitled as such to any
               preemptive or other rights to subscribe for any of the Shares;
               and no holder of securities of the Company has any right which
               has not been fully exercised or waived to require the Company to

               as a corporation in good standing under the laws of its
               jurisdiction of incorporation and is duly qualified to transact
               business as a foreign corporation and is in good standing under
               the laws of all other jurisdictions where the ownership, leasing
               or operation of its properties or assets or the conduct of its
               business requires such qualification, except where the failure to
               be so qualified does not amount to a material liability or
               disability to the Company; the Company has full power and
               authority to own, lease and operate its properties and assets and
               conduct its business as described in the

               (viii) the statements set forth under the heading "Description
               of Capital Stock" in the Prospectus, insofar as such statements
               purport to summarize certain provisions of the capital stock of
               the Company, provide a fair summary of such provisions; and the
               statements set forth under the headings "Risk Factors--Dependence
               on Key Personnel," "--Certain Anti-Takeover Provisions," and
               "--Shares Eligible for Future Sale," "Management--Limitation on

               Arrangements," "Certain Transactions," "Principal Stockholders,"
               and "Shares Eligible for Future Sale" in the Prospectus, insofar
               as such statements constitute a summary of the legal matters,
               documents or proceedings referred to therein, have been reviewed
               by such counsel and fairly present the information called for
               with respect to such legal matters, documents and proceedings in
               all material respects as required by the Securities Act and the
               rules and regulations thereunder;

               (ix)   the execution and delivery of this Agreement have been
               duly authorized by all necessary corporate action of the Company
               and this Agreement has been duly executed and delivered by the
               Company;

               (x)    the issuance, offering and sale of the Shares to the
               Underwriters by the Company pursuant to this Agreement, the
               compliance by the Company with the other provisions of this
               Agreement and the consummation of the other transactions herein
               contemplated do not (x) require the consent, approval,
               authorization, registration or qualification of or with any
               governmental authority, except such as have been obtained or made
               (and specified in such opinion) or such as may be required by the
               securities or Blue Sky laws of the various states of the United
               States of America and other U.S. jurisdictions in connection with
               the offer and sale of the Shares by the Underwriters, or (y)
               conflict with or result in a breach or violation of any of the
               terms and provisions of, or constitute a default under (I) any
               indenture, mortgage, deed of trust, lease or other agreement or
               instrument, known to such counsel, to which the Company is a
               party or by which the Company or any of its properties is bound,
               and which is either required to be filed as an exhibit to the
               Registration Statement or is an agreement with a customer of the
               Company identified in the Prospectus, or (II) the charter
               documents or by-laws of the Company, or any statute or any
               judgment, decree, order, rule or regulation of any court or other
               governmental authority or any arbitrator known to such counsel
               and applicable to the Company;

<PAGE>
 
               (xi)   the Company is not an "investment company" and, after
               giving effect to the Offering and the application of the proceeds
               therefrom, will not be an "investment company", as such term is
               defined in the 1940 Act; and

               (xii)  such counsel does not know of any legal or governmental
               proceedings pending or threatened to which the Company is a party
               or to which the property of the Company is subject that are
               required to be described in the Registration Statement or the
               Prospectus and are not described therein or any statutes,
               regulations, contracts or other documents that are required to be
               described in the Registration Statement or the Prospectus or to
               be filed as exhibits to the Registration Statement that are not
               described therein or filed as required.

          In rendering any such opinion, such counsel may rely, as to matters of
fact, to the extent such counsel deems proper, on certificates of responsible
officers of the Company and public officials and, as to matters involving the
application of laws of any jurisdiction other than the States of Delaware and
California or the United States, to the extent satisfactory in form and scope to
counsel for the Underwriters, upon the opinion of local counsel. The foregoing
opinion shall also state that the Underwriters are justified in relying upon
such opinion of such local counsel, and copies of such opinion shall be
delivered to the Representatives and counsel for the Underwriters.

          References to the Registration Statement and the Prospectus in this
paragraph (b) shall include any amendment or supplement thereto at the date of
such opinion.  The opinions of issuer's counsel described herein shall be
rendered to the Underwriters at the request of the Company and shall so state
therein.

          (c)  The Representatives shall have received a legal opinion from
Wilson Sonsini Goodrich & Rosati, Professional Corporations, counsel for the
Selling Stockholders, dated the Closing Date, to the effect that:

               (i)    such Selling Stockholder has full power to enter into this
               Agreement, the Custody Agreement and the Power-of-Attorney and to
               sell, assign, transfer and deliver the Shares being sold by such
               Selling Stockholder hereunder in the manner provided in this
               Agreement and to perform its obligations under the Custody
               Agreement; this Agreement, the Custody Agreement and the 
               Power-of-Attorney have been duly executed and delivered by each
               Selling Stockholder; assuming due authorization, execution and
               delivery by the Custodian, the Custody Agreement and the 
               Power-of-Attorney are the legal, valid, binding and enforceable
               instruments of such Selling Stockholder, subject to applicable
               bankruptcy, insolvency and similar laws affecting creditors'
               rights generally and subject, as to enforceability, to general
               principles of equity (regardless of whether enforcement is sought
               in a proceeding in equity or at law);

               (ii)   the delivery by each Selling Stockholder to the several
               Underwriters of certificates for the Shares being sold hereunder
               by such Selling Stockholder against payment therefor as provided
               herein, will convey good 

                                      28
<PAGE>
 
               and marketable title to such Shares to the several Underwriters,
               free and clear of all security interests, liens, encumbrances,
               equities, claims or other defects;

               (iii)  the sale of the Shares to the Underwriters by such Selling
               Stockholder pursuant to this Agreement, the compliance by such
               Selling Stockholder with the other provisions of this Agreement
               and the Custody Agreement and the consummation of the other
               transactions herein contemplated do not (x) require the consent,
               approval, authorization, registration or qualification of or with
               any governmental authority, except such as have been obtained and
               such as may be required under state securities or Blue Sky laws,
               or (y) conflict with or result in a breach or violation of any of
               the terms and provisions of, or constitute a default under any
               indenture, mortgage, deed of trust, lease or other agreement or
               instrument to which, to the best of such counsel's knowledge,
               such Selling Stockholder is a party or by which such Selling
               Stockholder or any of such Selling Stockholder's properties are
               bound, or any statute, rule or regulation or, to the best of such
               counsel's knowledge, any judgment, decree, order of any court or
               other governmental authority or any arbitrator applicable to such
               Selling Stockholder.


          In rendering such opinion, such counsel may rely, as to matters of
fact, to the extent such counsel deems proper, on certificates of the Selling
Stockholders and public officials and, as to matters involving the application
of laws of any jurisdiction other than the State of California or the United
States, to the extent satisfactory in form and scope to counsel for the
Underwriters, upon the opinion of local counsel.  The foregoing opinion shall
also state that the Underwriters are justified in relying upon such opinion of
such local counsel, and copies of such opinion shall be delivered to the
Representatives and counsel for the Underwriters.

          References to the Registration Statement and the Prospectus in this
paragraph (c) shall include any amendment or supplement thereto at the date of
such opinion.

          (d)  The Representatives shall have received a legal opinion from
Fenwick & West LLP, counsel for the Underwriters, dated the Closing Date,
covering the issuance and sale of the Shares, the Registration Statement and the
Prospectus, and such other related matters as the Representatives may reasonably
require, and the Company shall have furnished to such counsel such documents as
they may reasonably request for the purpose of enabling them to pass upon such
matters.

          (e)  The Representatives shall have received from Coopers & Lybrand
L.L.P. a letter or letters dated, respectively, the date hereof and the Closing
Date, in form and substance satisfactory to the Representatives, to the effect
that:

               (i)    they are independent accountants with respect to the
               Company within the meaning of the Securities Act and the
               applicable rules and regulations thereunder;

               (ii)   in their opinion, the audited financial statements and
               schedule examined by them and included in the Registration
               Statement and the Prospectus comply in form in all material
               respects with the applicable 

                                      29
<PAGE>
 
               accounting requirements of the Securities Act and the related
               published rules and regulations;

               (iii)  on the basis of a reading of the latest available interim
               unaudited financial statements of the Company, carrying out
               certain specified procedures (which do not constitute an
               examination made in accordance with generally accepted auditing
               standards) that would not necessarily reveal matters of
               significance with respect to the comments set forth in this
               paragraph (iii), a reading of the minute books of the
               stockholders, the board of directors and any committees thereof
               of the Company, and inquiries of certain officials of the Company
               who have responsibility for financial and accounting matters,
               nothing came to their attention that caused them to believe that:

                      (x)     the unaudited financial statements of the Company
                      included in the Registration Statement and the Prospectus
                      do not comply in form in all material respects with the
                      applicable accounting requirements of the Securities Act
                      and the related published rules and regulations thereunder
                      or are not in conformity with GAAP applied on a basis
                      substantially consistent with that of the audited
                      financial statements included in the Registration
                      Statement and the Prospectus;

                      (y)     at a specific date not more than five business
                      days prior to the date of such letter, there were any
                      changes in the capital stock or long-term debt of the
                      Company or any decreases in net current assets or
                      stockholders' equity of the Company, in each case compared
                      with amounts shown on the December 31, 1997 balance sheet
                      included in the Registration Statement and the Prospectus,
                      or for the period from January 1, 1998 to such specified
                      date there were any decreases, as compared with a period
                      of comparable length commencing on October 1, 1997, in
                      revenue, net income before provision for income taxes or
                      total or per share amounts of net income of the Company,
                      except in all instances for changes, decreases or
                      increases set forth in such letter.

               (iv)   they have carried out certain specified procedures, not
               constituting an audit, with respect to certain amounts,
               percentages and financial information that are derived from the
               general accounting records of the Company and are included in the
               Registration Statement and the Prospectus under the captions
               "Prospectus Summary," "Risk Factors," "Use of Proceeds,"
               "Capitalization," "Dilution," "Selected Financial Data,"
               "Management's Discussion and Analysis of Financial Condition and
               Results of Operations," "Business," "Management," "Certain
               Transactions," "Principal Stockholders," "Description of Capital
               Stock," "Shares Eligible for Future Sales" and "Item 15. Recent
               Sales of Unregistered Securities" and in Exhibit 11.01 to the
               Registration Statement, and have compared such amounts,
               percentages and

                                      30
<PAGE>
 
               financial information with such records of the Company and with
               information derived from such records and have found them to be
               in agreement, excluding any questions of legal interpretation.

          In the event that the letters referred to above set forth any such
changes, decreases or increases, it shall be a further condition to the
obligations of the Underwriters that (I) such letters shall be accompanied by a
written explanation of the Company as to the significance thereof, unless the
Representatives deem such explanation unnecessary, and (II) such changes,
decreases or increases do not, in the sole judgment of the Representatives, make
it impractical or inadvisable to proceed with the purchase and delivery of the
Shares as contemplated by the Registration Statement, as amended as of the date
hereof.  References to the Registration Statement and the Prospectus in this
paragraph (e) with respect to either letter referred to above shall include any
amendment or supplement thereto at the date of such letter.

          (f)  The Company shall have furnished or caused to be furnished to the
Underwriters at the Closing a certificate of its President and Chief Executive
Officer and its Vice President, Finance and Chief Financial Officer satisfactory
to the Underwriters to the effect that:

               (i)    the representations and warranties of the Company in this
               Agreement are true and correct as if made on and as of the
               Closing Date; the Registration Statement, as amended as of the
               Closing Date, does not include any untrue statement of a material
               fact or omit to state any material fact necessary to make the
               statements therein not misleading, and the Prospectus, as amended
               or supplemented as of the Closing Date, does not include any
               untrue statement of a material fact or omit to state any material
               fact necessary in order to make the statements therein, in the
               light of the circumstances under which they were made, not
               misleading; and the Company has performed all covenants and
               agreements and satisfied all conditions on its part to be
               performed or satisfied at or prior to the Closing Date;

               (ii)   no stop order suspending the effectiveness of the
               Registration Statement or any amendment thereto has been issued,
               and no proceedings for that purpose have been instituted or
               threatened or, to the best of the Company's knowledge, are
               contemplated by the Commission; and

               (iii)  subsequent to the respective dates as of which information
               is given in the Registration Statement and the Prospectus, the
               Company has not sustained any material loss or interference with
               its business as described in the Prospectus or properties from
               fire, flood, hurricane, accident or other calamity, whether or
               not covered by insurance, or from any labor dispute or any legal
               or governmental proceeding, and there has not been any materially
               adverse change (including, without limitation, a change in
               management or control), or development involving a prospective
               materially adverse change, in the condition (financial or
               otherwise), management, earnings, properties, business affairs or
               business prospects, stockholders' equity, net worth or results of
               operations of the

                                      31

               Company, except in each case as described in or contemplated by
               the Prospectus (exclusive of any amendment or supplement
               thereto).

          (g)  The Representatives shall have received from each Selling
Stockholder a certificate, signed by such Selling Stockholder, dated the Closing
Date, to the effect that:

               (i)    the representations and warranties of such Selling
               Stockholder in this Agreement are true and correct as if made on
               and as of the Closing Date; 

               (ii)   the Registration Statement, as amended as of the Closing
               Date, does not include any untrue statement of a material fact or
               omit to state any material fact necessary to make the statements
               therein not misleading, and the Prospectus, as amended or
               supplemented as of the Closing Date, does not include any untrue
               statement of a material fact or omit to state any material fact
               necessary in order to make the statements therein, in the light
               of the circumstances under which they were made, not misleading;
               and

               (iii)  such Selling Stockholder has performed all covenants and
               agreements on its part to be performed or satisfied at or prior

Selling Stockholders.

          All opinions, certificates, letters and documents delivered pursuant

satisfactory in all material respects to the Representatives and counsel for the
Underwriters.  The Company and the Selling Stockholders shall furnish to the
Representatives such conformed copies of such opinions, certificates, letters
and documents in such quantities as the Representatives and counsel for the
Underwriters shall reasonably request.

          The respective obligations of the several Underwriters to purchase and
pay for any Shares shall be subject, in their discretion, to each of the
foregoing conditions to purchase the Shares, except that all references therein
to the Shares and the Closing Date shall be deemed to refer to the Firm Shares
or the Option Shares and the First Closing Date or the related Option Closing
Date, each as applicable.

Section 8.  Default of Underwriters.  If, at any Closing, any one or more of the
            -----------------------                                             
Underwriters shall fail or refuse to purchase Shares that it has or they have
agreed to purchase hereunder on such date, and the aggregate number of Shares
which such defaulting Underwriter or Underwriters agreed but failed or refused
to purchase is ten percent or less of the aggregate number of the Shares to be
purchased on such date, the other Underwriters may make arrangements
satisfactory to the Representatives for the purchase of such Shares by other
persons (who may include one or more of the non-defaulting Underwriters,
including the Representatives), but if no such arrangements are made by the
First Closing Date or the related Option Closing Date, as the case may be, the
other Underwriters shall be obligated severally in the proportions that the
number of Firm Shares set forth opposite their respective names in Schedule 1
hereto bears to the aggregate number of Firm Shares set forth opposite the names
of all such non-defaulting Underwriters, or in such other proportions as the
Representatives may specify, to purchase the Shares which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase on such
date.  If, at the First Closing, any Underwriter or Underwriters shall fail or
refuse to purchase Firm Shares and the aggregate number of Firm Shares with
respect to which such default occurs is more than ten per cent of the aggregate
number of Firm Shares to be purchased, and arrangements satisfactory to the
Representatives, the Company and the Selling Stockholders for the purchase of
such Firm Shares are not made within 36 hours after such default, this Agreement
shall terminate without liability on the part of any non-defaulting Underwriter,
the Company or any Selling Stockholder.  In any such case either the
Representatives or the Company shall have the right to postpone the Closing, but
in no event for longer than seven days, in order that the required changes, if
any, in the Registration Statement and in the Prospectus or in any other
documents or arrangements may be effected.  If, at any Option Closing, any
Underwriter or Underwriters shall fail or refuse to purchase Option Shares, the
non-defaulting Underwriters shall have the option to (i) terminate their
obligation hereunder to purchase 

                                      33
<PAGE>
 
Option Shares or (ii) purchase not less than the number of Option Shares that
such non-defaulting Underwriters would have been obligated to purchase in the
absence of such default. As used in this Agreement, the term "Underwriter"
includes any person substituted for an Underwriter under this Section 8. Any
action taken under this Section 8 shall not relieve any defaulting Underwriter
from liability in respect of any default of such Underwriter under this
Agreement.

Section 9.  Termination.  This Agreement shall be subject to termination in the
            -----------
sole discretion of the Representatives by notice to the Company and the Selling
Stockholders given prior to any Closing Date in the event that the Company or
any Selling Stockholder shall have failed, refused or been unable to perform all
obligations and satisfy all conditions on its part to be performed or satisfied
hereunder at or prior thereto or, if at or prior to any Closing Date, (a)
trading in securities generally on the New York Stock Exchange or the Nasdaq
National Market shall have been suspended or materially limited or minimum or
maximum prices shall have been established by or on, as the case may be, the
Commission or the New York Stock Exchange or the Nasdaq National Market; (b)
trading of any securities of the Company shall have been suspended on any
exchange or in any over-the-counter market; (c) a general moratorium on
commercial banking activities shall have been declared by Federal, New York
State or California authorities; (d) there shall have occurred (i) an outbreak
or escalation of hostilities between the United States and any foreign power,
(ii) an outbreak or escalation of any other insurrection or armed conflict
involving the United States, or (iii) any other calamity or crisis or materially
adverse change in general economic, political or financial conditions having an
effect on the U.S. financial markets that, in the sole judgment of the
Representatives, makes it impractical or inadvisable to proceed with the public
offering or the delivery of the Shares as contemplated by the Registration
Statement, as amended as of the date hereof; or (e) the Company shall have, in
the sole judgment of the Representatives, sustained any material loss or
interference with its business as described in the Prospectus or properties from
fire, flood, hurricane, accident or other calamity, whether or not covered by
insurance, or from any labor dispute or any legal or governmental proceeding, or
there shall have been any materially adverse change (including, without
limitation, a change in management or control), or constitute a development
involving a prospective materially adverse change, in the condition (financial
or otherwise), management, earnings, properties, business affairs or business
prospects, stockholders' equity, net worth or results of operations of the
Company, except in each case as described in or contemplated by the Prospectus
(exclusive of any amendment or supplement thereto). Termination of this
Agreement pursuant to this Section 9 shall be without liability of any party to
any other party except for the liability of the Company in relation to expenses
as provided in Sections 4 and 10 hereof, the liability of the Selling
Stockholders in relation to expenses as provided in Sections 4 and 10 hereof,
the indemnity provided in Section 6 hereof and any liability arising before or
in relation to such termination.

Section 10.  Reimbursement of Expenses.  If the sale of the Shares provided for
             -------------------------
herein is not consummated because any condition to the obligations of the
Underwriters set forth in Section 7 hereof is not satisfied or because of any
termination pursuant to Section 9 hereof (other than by reason of a default by
any of the Underwriters), the Company shall reimburse the Underwriters,
severally upon demand, for all out-of-pocket expenses (including fees and
disbursements of counsel) that shall have been incurred by them in connection
with the proposed purchase and sale of the Shares. If the Company is required to
make any payments to the Underwriters under this Section 10 because of any
Selling Stockholder's refusal, inability or failure to satisfy any condition

                                      34
<PAGE>
 
to the obligations of the Underwriters set forth in Section 7 hereof, such
defaulting Selling Stockholder, pro rata in proportion to the percentage of
                                --- ---- 
Shares to be sold by each, shall reimburse the Company on demand for all amounts
so paid.

Section 11.  Information Supplied by Underwriters.  The statements set forth in

relate to the Underwriters) constitute the only information furnished by any
