described in the Prospectus, the employment of each officer and employee of the
Company is terminable at the will of the Company.  To its knowledge, the Company

any term of any employment contract, proprietary information agreement or any
other agreement relating to the right of any such individual to be employed by,
or to contract with, the Company because of the nature of the business to be
conducted by the Company; and to the Company's knowledge, the continued
employment by the Company of its present employees, and the performance of the

such violation.  The Company has not received any notice alleging that any such
violation has occurred.  Except as described in the Prospectus, no employee of
the Company has been granted the right to continued employment by the Company or
to any other material compensation following termination of employment with the
Company.  The Company is not aware that any officer or employee, 

                                      5



or that any group of employees, intends to terminate their employment with 
the Company, nor does the Company have a present intention to terminate the 
employment of any of the foregoing.

corporation ("Imgis"), has been duly authorized by all necessary board of
directors and stockholder action on the part of the Company and Imgis and has
been duly executed and delivered by each of the parties thereto.  The execution
and delivery of the Plan of Merger and the consummation of the merger
contemplated thereby does not contravene any provision of applicable federal,  
Delaware corporate or California law or the certificate of incorporation or
bylaws of the Company or the certificate of incorporation or bylaws of Imgis,
or, to the knowledge of the Company, any judgment or decree of any governmental
body, agency or court having jurisdiction over the Company or Imgis, and no
consent, approval, authorization or order of or qualification with any
governmental body or agency is required for the performance by the Company and
Imgis of its obligations under the Plan of Merger except such as have been

trade journalist or publication to write or publish favorable information about
the Company or its products.

               (xxv)   To the Company's knowledge, after due investigation, each
of the Company's products will produce no material, logical or arithmetic
inconsistencies when dealing with leap years or dates beyond the year 1999. 
Without limiting the foregoing, to the Company's knowledge, the Company's
services will not materially impede the accurate processing of data, or cause
programming or processing errors resulting from the rollover of two-digit year
values to "00" on January 1, 2000.  The foregoing does not constitute a warranty
or representation that the Company's software will be capable of recording,
storing, processing, calculating and displaying correct calendar dates based on
software supplied by any party other than the Company, or that other Company's
software will properly interact with such third party software.

               (xxvi)  No consent, approval, authorization or order of any
federal, Delaware or California governmental agency or body is required on the
part of the Company for the consummation of the transactions contemplated
herein, except such as have been obtained under the Securities Act and such as
may be required under state securities or blue sky laws in connection with the
purchase and distribution of the Stock by the Underwriters.

     3.   PURCHASE OF THE STOCK BY THE UNDERWRITERS.

(a)  On the basis of the representations and warranties and subject to the terms
     and conditions herein set forth, the Company agrees to issue and sell
     _________ shares of the Underwritten Stock to the several Underwriters, and
     each of the Underwriters agrees to purchase from the Company the respective
     aggregate number of shares of Underwritten Stock set forth opposite its
     name in Schedule I.  The price at which such shares of Underwritten Stock
     shall be sold by the Company and purchased by the several Underwriters
     shall be $___ per share.  The obligation of each Underwriter to the Company
     shall be to purchase from the Company that number of shares of the
     Underwritten Stock set forth opposite the name of such Underwriter in
     Schedule I hereto.  In making this Agreement, each Underwriter is
     contracting severally and not jointly; except as provided in paragraphs (b)
     and (c) of this Section 3, the agreement of each Underwriter is to purchase
     only the respective number of shares of the Underwritten Stock specified in
     Schedule I.

(b)  If for any reason one or more of the Underwriters shall fail or refuse
     (otherwise than for a reason sufficient to justify the termination of this
     Agreement under the provisions of Section 8 or 9 hereof) to purchase and
     pay for the number of shares of the Stock agreed to be purchased by such
     Underwriter or Underwriters, the Company shall immediately give notice
     thereof to you, and the non-defaulting Underwriters shall have the right
     within 24 hours after the receipt by you of such notice to purchase, or
     procure one or more other Underwriters to purchase, in such proportions as
     may be agreed upon between you and such purchasing Underwriter or
     Underwriters and upon the terms herein set 

                                      6



     forth, all or any part of the shares of the Stock which such defaulting 
     Underwriter or Underwriters agreed to purchase.  If the non-defaulting 
     Underwriters fail so to make such arrangements with respect to all such 
     shares and portion, the number of shares of the Stock which each 
     non-defaulting Underwriter is otherwise obligated to purchase under this 
     Agreement shall be automatically increased on a pro rata basis to absorb 
     the remaining shares and portion which the defaulting Underwriter or 
     Underwriters agreed to purchase; PROVIDED, HOWEVER, that the 
     non-defaulting Underwriters shall not be obligated to purchase the 
     shares and portion which the defaulting Underwriter or Underwriters 
     agreed to purchase if the aggregate number of such shares of the Stock 
     exceeds 10% of the total number of shares of the Stock which all 
     Underwriters agreed to purchase hereunder.  If the total number of 
     shares of the Stock which the defaulting Underwriter or Underwriters 
     agreed to purchase shall not be purchased or absorbed in accordance with 
     the two preceding sentences, the Company shall have the right, within 24 
     hours next succeeding the 24-hour period above referred to, to make 
     arrangements with other underwriters or purchasers satisfactory to you 
     for purchase of such shares and portion on the terms herein set forth.  
     In any such case, either you or the Company shall have the right to 
     postpone the Closing Date determined as provided in Section 5 hereof for 
     not more than seven business days after the date originally fixed as the 
     Closing Date pursuant to said Section 5 in order that any necessary 
     changes in the Registration Statement, the Prospectus or any other 
     documents or arrangements may be made.  If neither the non-defaulting 
     Underwriters nor the Company shall make arrangements within the 24-hour 
     periods stated above for the purchase of all the shares of the Stock 
     which the defaulting Underwriter or Underwriters agreed to purchase 
     hereunder, this Agreement shall be terminated without further act or 
     deed and without any liability on the part of the Company to any 
     non-defaulting Underwriter and without any liability on the part of any 
     non-defaulting Underwriter to the Company. Nothing in this paragraph 
     (b), and no action taken hereunder, shall relieve any defaulting 
     Underwriter from liability in respect of any default of such Underwriter 
     under this Agreement.

(c)  On the basis of the representations, warranties and covenants herein
     contained, and subject to the terms and conditions herein set forth, the
     Company grants an option to the several Underwriters to purchase, severally
     and not jointly, up to _____________ shares in the aggregate of the Option
     Stock from the Company at the same price per share as the Underwriters
     shall pay for the Underwritten Stock.  Said option may be exercised only to
     cover over-allotments in the sale of the Underwritten Stock by the
     Underwriters and may be exercised in whole or in part at any time (but not
     more than once) on or before the thirtieth day after the date of this
     Agreement upon written or telegraphic notice by you to the Company setting
     forth the aggregate number of shares of the Option Stock as to which the
     several Underwriters are exercising the option.  Delivery of certificates
     for the shares of Option Stock, and payment therefor, shall be made as
     provided in Section 5 hereof.  The number of shares of the Option Stock to
     be purchased by each Underwriter shall be the same percentage of the total
     number of shares of the Option Stock to be purchased by the several
     Underwriters as such Underwriter is purchasing of the Underwritten Stock,
     as adjusted by you in such manner as you deem advisable to avoid fractional
     shares.

          4.   OFFERING BY UNDERWRITERS.

(a)  The terms of the initial public offering by the Underwriters of the Stock
     to be purchased by them shall be as set forth in the Prospectus.  The
     Underwriters may from time to time change the public offering price after
     the closing of the initial public offering and increase or decrease the
     concessions and discounts to dealers as they may determine.

(b)  The information set forth in the last paragraph on the front cover page and
     under "Underwriting" in the Registration Statement, any Preliminary
     Prospectus and the Prospectus relating to the Stock filed by the Company
     (insofar as such information relates to the Underwriters) constitutes the
     only information furnished by the Underwriters to the Company for inclusion
     in the Registration Statement, any Preliminary Prospectus, and the
     Prospectus, and you on behalf of the respective Underwriters represent and
     warrant to the Company that the statements made therein are correct.

          5.   DELIVERY OF AND PAYMENT FOR THE STOCK.

(a)  Delivery of certificates for the shares of the Underwritten Stock and the
     Option Stock (if the option granted by Section 3(c) hereof shall have been
     exercised not later than 7:00 A.M., San Francisco time, on the date two
     business 

                                      7



     days preceding the Closing Date), and payment therefor, shall be
     made at the office of Fenwick & West LLP, at 7:00 a.m., San Francisco time,
     on the fourth business day after the date of this Agreement, or at such
     time on such other day, not later than seven full business days after such
     fourth business day, as shall be agreed upon in writing by the Company and
     you.  The date and hour of such delivery and payment (which may be
     postponed as provided in Section 3(b) hereof) are herein called the Closing
     Date.

(b)  If the option granted by Section 3(c) hereof shall be exercised after
     7:00 a.m., San Francisco time, on the date two business days preceding the
     Closing Date, delivery of certificates for the shares of Option Stock, and
     payment therefor, shall be made at the office of Fenwick & West LLP, at
     7:00 a.m., San Francisco time, on the third business day after the exercise
     of such option.

(c)  Payment for the Stock purchased from the Company shall be made to the
     Company or its order by one or more certified or official bank check or
     checks in same day funds.   Such payment shall be made upon delivery of
     certificates for the Stock to you for the respective accounts of the
     several Underwriters against receipt therefor signed by you.  Certificates
     for the Stock to be delivered to you shall be registered in such name or
     names and shall be in such denominations as you may request at least one
     business day before the Closing Date, in the case of Underwritten Stock,
     and at least one business day prior to the purchase thereof, in the case of
     the Option Stock.  Such certificates will be made available to the
     Underwriters for inspection, checking and packaging at the offices of Lewco
     Securities Corporation, 2 Broadway, New York, New York 10004 on the
     business day prior to the Closing Date or, in the case of the Option Stock,
     by 3:00 p.m., New York time, on the business day preceding the date of
     purchase.

          It is understood that you, individually and not on behalf of the
     Underwriters, may (but shall not be obligated to) make payment to the
     Company for shares to be purchased by any Underwriter whose check shall not
     have been received by you on the Closing Date or any later date on which
     Option Stock is purchased for the account of such Underwriter.  Any such
     payment by you shall not relieve such Underwriter from any of its
     obligations hereunder.

          6.   FURTHER AGREEMENTS OF THE COMPANY.  The Company further covenants
     and agrees as follows:

(a)  The Company will (i) prepare and timely file with the Commission under Rule
     424(b) a Prospectus containing information previously omitted at the time
     of effectiveness of the Registration Statement in reliance on Rule 430A and
     (ii) not file any amendment to the Registration Statement or supplement to
     the Prospectus of which you shall not previously have been advised and
     furnished with a copy or to which you shall have reasonably objected in
     writing or which is not in compliance with the Securities Act or the rules
     and regulations of the Commission.

(b)  The Company will promptly notify each Underwriter in the event of (i) the
     request by the Commission for amendment of the Registration Statement or
     for supplement to the Prospectus or for any additional information, (ii)
     the issuance by the Commission of any stop order suspending the
     effectiveness of the Registration Statement, (iii) the institution or
     notice of intended institution by the Commission of any action or
     proceeding for that purpose, (iv) the receipt by the Company of any
     notification with respect to the suspension of the qualification of the
     Stock for sale in any jurisdiction, or (v) the receipt by the Company of
     notice of the initiation or threatening of any proceeding for such purpose.
     The Company will make every reasonable effort to prevent the issuance of
     such a stop order and, if such an order shall at any time be issued, to
     obtain the withdrawal thereof at the earliest possible moment.

(c)  The Company will (i) on or before the Closing Date, deliver to you a
     conformed copy of the Registration Statement as originally filed and of
     each amendment thereto filed prior to the time the Registration Statement
     becomes effective and, promptly upon the filing thereof, a conformed copy
     of each post-effective amendment, if any, to the Registration Statement
     (together with, in each case, all exhibits thereto unless previously
     furnished to you) and will also deliver to you, for distribution to the
     Underwriters, a sufficient number of additional conformed copies of each of
     the foregoing (but without exhibits) so that one copy of each may be
     distributed to each Underwriter, (ii) as promptly as possible deliver to
     you and send to the several Underwriters, at such office or offices as you
     may designate, as many copies of the Prospectus as you may reasonably
     request, and (iii) thereafter from time to time 

                                      8



     during the period in which a prospectus is required by law to be 
     delivered by an Underwriter or dealer, likewise send to the Underwriters 
     as many additional copies of the Prospectus and as many copies of any 
     supplement to the Prospectus and of any amended prospectus, filed by the 
     Company with the Commission, as you may reasonably request for the 
     purposes contemplated by the Securities Act.

(d)  If at any time during the period in which a prospectus is required by law
     to be delivered by an Underwriter or dealer any event relating to or
     affecting the Company, or of which the Company shall be advised in writing
     by you, shall occur as a result of which it is necessary, in the opinion of
     counsel for the Company or of counsel for the Underwriters, to supplement
     or amend the Prospectus in order to make the Prospectus not misleading in
     the light of the circumstances existing at the time it is delivered to a
     purchaser of the Stock, the Company will forthwith prepare and file with
     the Commission a supplement to the Prospectus or an amended prospectus so
     that the Prospectus as so supplemented or amended will not contain 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 existing at the time such Prospectus is delivered to such
     purchaser, not misleading.  If, after the initial public offering of the
     Stock by the Underwriters and during such period, the Underwriters shall
     propose to vary the terms of offering thereof by reason of changes in
     general market conditions or otherwise, you will advise the Company in
     writing of the proposed variation, and, if in the opinion either of counsel
     for the Company or of counsel for the Underwriters such proposed variation
     requires that the Prospectus be supplemented or amended, the Company will
     forthwith prepare and file with the Commission a supplement to the
     Prospectus or an amended prospectus setting forth such variation.  The
     Company authorizes the Underwriters and all dealers to whom any of the
     Stock may be sold by the several Underwriters to use the Prospectus, as
     from time to time amended or supplemented, in connection with the sale of
     the Stock in accordance with the applicable provisions of the Securities
     Act and the applicable rules and regulations thereunder for such period.

(e)  Prior to the filing thereof with the Commission, the Company will submit to
     you, for your information, a copy of any post-effective amendment to the
     Registration Statement and any supplement to the Prospectus or any amended
     prospectus proposed to be filed.

(f)  The Company will cooperate, when and as requested by you, in the
     qualification of the Stock for offer and sale under the securities or blue
     sky laws of such jurisdictions as you may designate and, during the period
     in which a prospectus is required by law to be delivered by an Underwriter
     or dealer, in keeping such qualifications in good standing under said
     securities or blue sky laws; PROVIDED, HOWEVER, that the Company shall not
     be obligated to file any general consent to service of process or to
     qualify as a foreign corporation in any jurisdiction in which it is not so
     qualified.  The Company will, from time to time, prepare and file such
     statements, reports, and other documents as are or may be required to
     continue such qualifications in effect for so long a period as you may
     reasonably request for distribution of the Stock.

(g)  During a period of five years commencing with the date hereof, the Company
     will furnish to you, and to each Underwriter who may so request in writing,
     copies of all periodic and special reports furnished to stockholders of the
     Company and of all information, documents and reports filed with the
     Commission.

(h)  Not later than the 45th day following the end of the fiscal quarter first
     occurring after the first anniversary of the Effective Date, the Company
     will make generally available to its security holders an earnings statement
     in accordance with Section 11(a) of the Securities Act and Rule 158
     thereunder.

(i)  The Company agrees to pay all costs and expenses incident to the
     performance of obligations under this Agreement, including all costs and
     expenses (excluding counsel fees for Underwriters) incident to (i) the
     preparation, printing and filing with the Commission and the National
     Association of Securities Dealers, Inc. ("NASD") of the Registration
     Statement, any Preliminary Prospectus and the Prospectus, (ii) the
     furnishing to the Underwriters of copies of any Preliminary Prospectus and
     of the several documents required by paragraph (c) of this Section 6 to be
     so furnished, (iii) the printing of this Agreement and related documents
     delivered to the Underwriters, (iv) the preparation, printing and filing of
     all supplements and amendments to the Prospectus referred to in
     paragraph (d) of this Section 6, (v) the furnishing to you and the
     Underwriters of the reports and information referred to in 

                                      9



     paragraph (g) of this Section 6 and (vi) the printing and issuance of 
     stock certificates, including the transfer agent's fees.

(j)  The Company agrees to reimburse you, for the account of the several
     Underwriters, for blue sky fees and related disbursements (including
     counsel fees and disbursements and cost of printing memoranda for the
     Underwriters) paid by or for the account of the Underwriters or their
     counsel in qualifying the Stock under state securities or blue sky laws and
     in the review of the offering by the National Association of Securities
     Dealers, Inc.

(k)  THE COMPANY HEREBY AGREES THAT, WITHOUT THE PRIOR WRITTEN CONSENT OF
     HAMBRECHT & QUIST LLC ON BEHALF OF THE UNDERWRITERS, THE COMPANY WILL NOT,
     FOR A PERIOD OF 180 DAYS FOLLOWING THE EFFECTIVE DATE, DIRECTLY OR
     INDIRECTLY, (i) SELL, OFFER, CONTRACT TO SELL, MAKE ANY SHORT SALE, PLEDGE,
     SELL ANY OPTION OR CONTRACT TO PURCHASE, PURCHASE ANY OPTION OR CONTRACT TO
     SELL, GRANT ANY OPTION, RIGHT OR WARRANT TO PURCHASE OR OTHERWISE TRANSFER
     OR DISPOSE OF ANY SHARES OF COMMON STOCK OR ANY SECURITIES CONVERTIBLE INTO
     OR EXCHANGEABLE OR EXERCISABLE FOR OR ANY RIGHTS TO PURCHASE OR ACQUIRE
     COMMON STOCK OR (ii) ENTER INTO ANY SWAP OR OTHER AGREEMENT THAT TRANSFERS,
     IN WHOLE OR IN PART, ANY OF THE ECONOMIC CONSEQUENCES OR OWNERSHIP OF
     COMMON STOCK, WHETHER ANY SUCH TRANSACTION DESCRIBED IN CLAUSE (i) OR (ii)
     ABOVE IS TO BE SETTLED BY DELIVERY OF COMMON STOCK OR SUCH OTHER
     SECURITIES, IN CASH OR OTHERWISE.  THE FOREGOING SENTENCE SHALL NOT APPLY
     TO (A) THE STOCK TO BE SOLD TO THE UNDERWRITERS PURSUANT TO THIS AGREEMENT,
     (B) SHARES OF COMMON STOCK ISSUED BY THE COMPANY UPON THE EXERCISE OF
     OPTIONS.

(l)  If at any time during the 25-day period after the Registration Statement
     becomes effective any rumor, publication or event relating to or affecting
     the Company shall occur as a result of which in your opinion the market
     price for the Stock 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
     written notice from you advising the Company to the effect set forth above,
     forthwith prepare, consult with you concerning the substance of, and
     disseminate a press release or other public statement, reasonably
     satisfactory to you, responding to or commenting on such rumor, publication
     or event.

(m)  The Company is familiar with the Investment Company Act of 1940, as
     amended, and has in the past conducted its affairs, and will in the future
     conduct its affairs, in such a manner to ensure that the Company was not
     and will not be an "investment company" or a company "controlled" by an
     "investment company" within the meaning of the Investment Company Act of
     1940, as amended, and the rules and regulations thereunder.

          7.   INDEMNIFICATION AND CONTRIBUTION.

(a)  Subject to the provisions of paragraph (f) of this Section 7, the Company
     agrees to indemnify and hold harmless each Underwriter and each person
     (including each partner or officer thereof) who controls any Underwriter
     within the meaning of Section 15 of the Securities Act from and against any
     and all losses, claims, damages or liabilities, joint or several, to which
     such indemnified parties or any of them may become subject under the
     Securities Act, the Securities Exchange Act of 1934, as amended (herein
     called the Exchange Act), or the common law or otherwise, and the Company
     agrees to reimburse each such Underwriter and controlling person for any
     legal or other expenses (including, except as otherwise hereinafter
     provided, reasonable fees and disbursements of counsel) incurred by the
     respective indemnified parties in connection with defending against any
     such losses, claims, damages or liabilities or in connection with any
     investigation or inquiry of, or other proceeding which may be brought
     against, the respective indemnified parties, in each case arising out of or
     based upon (i) any untrue statement or alleged untrue statement of a
     material fact contained in the Registration Statement (including the
     Prospectus as part thereof and any Rule 462(b) registration statement) or
     any post-effective amendment thereto (including any Rule 462(b)
     registration statement), or the omission or alleged omission to state
     therein a material fact required to be stated therein or necessary to make
     the statements therein not misleading, or (ii) any untrue statement or
     alleged untrue statement of a material fact contained in any Preliminary
     Prospectus or the Prospectus (as amended or as supplemented if the Company
     shall have filed with the Commission any amendment thereof or supplement
     thereto) or the omission or alleged omission to state therein a material
     fact necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; PROVIDED,
     HOWEVER, that (1) the indemnity agreements of the Company contained in this
     paragraph (a) shall not apply to any such losses, claims, damages,
     liabilities or 

                                      10



     expenses if such statement or omission was made in reliance
     upon and in conformity with information furnished as herein stated or
     otherwise furnished in writing to the Company by or on behalf of any
     Underwriter for use in any Preliminary Prospectus or the Registration
     Statement or the Prospectus or any such amendment thereof or supplement
     thereto, and (2) the indemnity agreement contained in this paragraph (a)
     with respect to any Preliminary Prospectus shall not inure to the benefit
     of any Underwriter from whom the person asserting any such losses, claims,
     damages, liabilities or expenses purchased the Stock which is the subject
     thereof (or to the benefit of any person controlling such Underwriter) if
     at or prior to the written confirmation of the sale of such Stock a copy of
     the Prospectus (or the Prospectus as amended or supplemented) was not sent
     or delivered to such person and the untrue statement or omission of a
     material fact contained in such Preliminary Prospectus was corrected in the
     Prospectus (or the Prospectus as amended or supplemented) unless the
     failure is the result of noncompliance by the Company with paragraph (c) of
     Section 6 hereof. The indemnity agreements of the Company contained in this
     paragraph (a) and the representations and warranties of the Company
     contained in Section 2 hereof shall remain operative and in full force and
     effect regardless of any investigation made by or on behalf of any
     indemnified party and shall survive the delivery of and payment for the
     Stock.

(b)  Each Underwriter severally agrees to indemnify and hold harmless the
     Company, each of its officers who signs the Registration Statement on his
     own behalf or pursuant to a power of attorney, each of its directors, each
     other Underwriter and each person (including each partner or officer
     thereof) who controls the Company or any such other Underwriter within the
     meaning of Section 15 of the Securities Act, from and against any and all
     losses, claims, damages or liabilities, joint or several, to which such
     indemnified parties or any of them may become subject under the Securities
     Act, the Exchange Act, or the common law or otherwise and to reimburse each
     of them for any legal or other expenses (including, except as otherwise
     hereinafter provided, reasonable fees and disbursements of counsel)
     incurred by the respective indemnified parties in connection with defending
     against any such losses, claims, damages or liabilities or in connection
     with any investigation or inquiry of, or other proceeding which may be
     brought against, the respective indemnified parties, in each case arising
     out of or based upon (i) any untrue statement or alleged untrue statement
     of a material fact contained in the Registration Statement (including the
     Prospectus as part thereof and any Rule 462(b) registration statement) or
     any post-effective amendment thereto (including any Rule 462(b)
     registration statement) or the omission or alleged omission to state
     therein a material fact required to be stated therein or necessary to make
     the statements therein not misleading or (ii) any untrue statement or
     alleged untrue statement of a material fact contained in the Prospectus (as
     amended or as supplemented if the Company shall have filed with the
     Commission any amendment thereof or supplement thereto) or the omission or
     alleged omission to state therein a material fact necessary in order to
     make the statements therein, in the light of the circumstances under which
     they were made, not misleading, if such statement or omission was made in
     reliance upon and in conformity with information furnished as herein stated
     or otherwise furnished in writing to the Company by or on behalf of such
     indemnifying Underwriter for use in the Registration Statement or the
     Prospectus or any such amendment thereof or supplement thereto.  The
     indemnity agreement of each Underwriter contained in this paragraph (b)
     shall remain operative and in full force and effect regardless of any
     investigation made by or on behalf of any indemnified party and shall
     survive the delivery of and payment for the Stock.

(c)  Each party indemnified under the provision of paragraphs (a) and (b) of
     this Section 7 agrees that, upon the service of a summons or other initial
     legal process upon it in any action or suit instituted against it or upon
     its receipt of written notification of the commencement of any
     investigation or inquiry of, or proceeding against, it in respect of which
     indemnity may be sought on account of any indemnity agreement contained in
     such paragraphs, it will promptly give written notice (herein called the
     Notice) of such service or notification to the party or parties from whom
     indemnification may be sought hereunder.  No indemnification provided for
     in such paragraphs shall be available to any party who shall fail so to
     give the Notice if the party to whom such Notice was not given was unaware
     of the action, suit, investigation, inquiry or proceeding to which the
     Notice would have related and was prejudiced by the failure to give the
     Notice, but the omission so to notify such indemnifying party or parties of
     any such service or notification shall not relieve such indemnifying party
     or parties from any liability which it or they may have to the indemnified
     party for contribution or otherwise than on account of such indemnity
     agreement.  Any indemnifying party shall be entitled at its own expense to
     participate in the defense of any action, suit or proceeding against, or
     investigation or inquiry of, an indemnified party.  Any indemnifying party
     shall be entitled, if it so elects within a reasonable time after receipt
     of the Notice by giving written notice (herein called the Notice of
     Defense) to the indemnified party, to assume (alone or in conjunction with
     any other indemnifying party or parties) the entire 

                                      11



     defense of such action, suit, investigation, inquiry or proceeding, in 
     which event such defense shall be conducted, at the expense of the 
     indemnifying party or parties, by counsel chosen by such indemnifying 
     party or parties and reasonably satisfactory to the indemnified party or 
     parties; PROVIDED, HOWEVER, that (i) if the indemnified party or parties 
     reasonably determine that there may be a conflict between the positions 
     of the indemnifying party or parties and of the indemnified party or 
     parties in conducting the defense of such action, suit, investigation, 
     inquiry or proceeding or that there may be legal defenses available to 
     such indemnified party or parties different from or in addition to those 
     available to the indemnifying party or parties, then counsel for the 
     indemnified party or parties shall be entitled to conduct the defense to 
     the extent reasonably determined by such counsel to be necessary to 
     protect the interests of the indemnified party or parties and (ii) in 
     any event, the indemnified party or parties shall be entitled to have 
     counsel chosen by such indemnified party or parties participate in, but 
     not conduct, the defense.  If, within a reasonable time after receipt of 
     the Notice, an indemnifying party gives a Notice of Defense and the 
     counsel chosen by the indemnifying party or parties is reasonably 
     satisfactory to the indemnified party or parties, the indemnifying party 
     or parties will not be liable under paragraphs (a) through (c) of this 
     Section 7 for any legal or other expenses subsequently incurred by the 
     indemnified party or parties in connection with the defense of the 
     action, suit, investigation, inquiry or proceeding, except that (A) the 
     indemnifying party or parties shall bear the legal and other expenses 
     incurred in connection with the conduct of the defense as referred to in 
     clause (i) of the proviso to the preceding sentence and (B) the 
     indemnifying party or parties shall bear such other expenses as it or 
     they have authorized to be incurred by the indemnified party or parties. 
     If, within a reasonable time after receipt of the Notice, no Notice of 
     Defense has been given, the indemnifying party or parties shall be 
     responsible for any legal or other expenses incurred by the indemnified 
     party or parties in connection with the defense of the action, suit, 
     investigation, inquiry or proceeding.

(d)  If the indemnification provided for in this Section 7 is unavailable or
     insufficient to hold harmless an indemnified party under paragraph (a) or
     (b) of this Section 7, then each indemnifying party, in lieu of
     indemnifying such indemnified party, shall contribute to the amount paid or
     payable by such indemnified party as a result of the losses, claims,
     damages or liabilities referred to in paragraph (a) or (b) of this Section
     7 (i) in such proportion as is appropriate to reflect the relative benefits
     received by each indemnifying party from the offering of the Stock or (ii)
     if the allocation provided by clause (i) above is not permitted by
     applicable law, in such proportion as is appropriate to reflect not only
     the relative benefits referred to in clause (i) above but also the relative
     fault of each indemnifying party in connection with the 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 on the one
     hand and the Underwriters on the other shall be deemed to be in the same
     respective proportions as the total net proceeds from the offering of the
     Stock received by the Company and the total underwriting discount received
     by the Underwriters, as set forth in the table on the cover page of the
     Prospectus, bear to the aggregate public offering price of the Stock.
     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 each indemnifying party and the parties' relative
     intent, knowledge, access to information and opportunity to correct or
     prevent such untrue statement or omission.  

          The parties agree that it would not be just and equitable if
     contributions pursuant to this paragraph (d) were to be determined by pro
     rata allocation (even if the Underwriters were treated as one entity for
     such purpose) or by any other method of allocation which does not take into
     account the equitable considerations referred to in the first sentence of
     this paragraph (d).  The amount paid by an indemnified party as a result of
     the losses, claims, damages or liabilities, or actions in respect thereof,
     referred to in the first sentence of this paragraph (d) shall be deemed to
     include any legal or other expenses reasonably incurred by such indemnified
     party in connection with investigation, preparing to defend or defending
     against any action or claim which is the subject of this paragraph (d).
     Notwithstanding the provisions of this paragraph (d), no Underwriter shall
     be required to contribute any amount in excess of the underwriting discount
     applicable to the Stock purchased by such Underwriter. 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 in this paragraph (d) to contribute are several in proportion
     to their respective underwriting obligations and not joint.  

                                      12



          Each party entitled to contribution agrees that upon the service of a
     summons or other initial legal process upon it in any action instituted
     against it in respect of which contribution may be sought, it will promptly
     give written notice of such service to the party or parties from whom
     contribution may be sought, but the omission so to notify such party or
     parties of any such service shall not relieve the party from whom
     contribution may be sought from any obligation it may have hereunder or
     otherwise (except as specifically provided in paragraph (c) of this
     Section 7).

(e)  The Company will not, without the prior written consent of each
     Underwriter, 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 such
     Underwriter or any person who controls such Underwriter within the meaning
     of Section 15 of the Securities Act or Section 20 of the Exchange Act is a
     party to such claim, action, suit or proceeding) unless such settlement,
     compromise or consent includes an unconditional release of such Underwriter
     and each such controlling person from all liability arising out of such
     claim, action, suit or proceeding. 

          8.   TERMINATION.  This Agreement may be terminated by you at any time
     prior to the Closing Date by giving written notice to the Company if after
     the date of this Agreement trading in the Common Stock shall have been
     suspended, or if there shall have occurred (i) the engagement in
     hostilities or an escalation of major hostilities by the United States or
     the declaration of war or a national emergency by the United States on or
     after the date hereof, (ii) any outbreak of hostilities or other national
     or international calamity or crisis or change in economic or political
     conditions if the effect of such outbreak, calamity, crisis or change in
     economic or political conditions in the financial markets of the United
     States would, in the Underwriters' reasonable judgment, make the offering
     or delivery of the Stock impracticable, (iii) suspension of trading in
     securities generally or a material adverse decline in value of securities
     generally on the New York Stock Exchange, the American Stock Exchange, or
     The Nasdaq Stock Market, or limitations on prices (other than limitations
     on hours or numbers of days of trading) for securities on either such
     exchange or system, (iv) the enactment, publication, decree or other
     promulgation of any federal or state statute, regulation, rule or order of,
     or commencement of any proceeding or investigation by, any court,
     legislative body, agency or other governmental authority which in the
     Underwriters' reasonable opinion materially and adversely affects or will
     materially and adversely affect the business or operations of the Company,
     (v) declaration of a banking moratorium by either federal or New York State
     authorities or (vi) the taking of any action by any federal, state or local
     government or agency in respect of its monetary or fiscal affairs which in
     the Underwriters' reasonable opinion has a material adverse effect on the
     securities markets in the United States.  If this Agreement shall be
     terminated pursuant to this Section 8, there shall be no liability of the
     Company to the Underwriters and no liability of the Underwriters to the
     Company; PROVIDED, HOWEVER, that in the event of any such termination the
     Company agrees to indemnify and hold harmless the Underwriters from all
     costs or expenses incident to the performance of the obligations of the
     Company under this Agreement, including all costs and expenses referred to
     in paragraphs (i) and (j) of Section 6 hereof.

          9.   CONDITIONS OF UNDERWRITERS' OBLIGATIONS.  The obligations of the
     several Underwriters to purchase and pay for the Stock shall be subject to
     the performance by the Company of all their respective obligations to be

     which Option Stock is to be purchased, as the case may be, and to the
     following further conditions:

(a)  The Registration Statement shall have become effective; and no stop order
     suspending the effectiveness thereof shall have been issued and no
     proceedings therefor shall be pending or threatened by the Commission.

(b)  The legality and sufficiency of the sale of the Stock hereunder and the
     validity and form of the certificates representing the Stock, all corporate
     proceedings and other legal matters incident to the foregoing, and the form
     of the Registration Statement and of the Prospectus (except as to the
     financial statements contained therein), shall have been approved at or
     prior to the Closing Date by Gunderson Dettmer Stough Villeneuve Franklin &
     Hachigian, LLP, counsel for the Underwriters.

(c)  You shall have received from Fenwick & West LLP, counsel for the Company,
     an opinion, addressed to the Underwriters and dated the Closing Date,
     covering the matters set forth in Annex A hereto, and if Option Stock is

                                      13



     purchased at any date after the Closing Date, an additional opinion from
     such counsel, addressed to the Underwriters and dated such later date,
     confirming that the statements expressed as of the Closing Date in such
     opinion remain valid as of such later date.

(d)  You shall be satisfied that (i) as of the Effective Date, the statements
     made in the Registration Statement and the Prospectus were true and correct
     and neither the Registration Statement nor the Prospectus omitted to state
     any material fact required to be stated therein or necessary in order to
     make the statements therein, respectively, not misleading, (ii) since the
     Effective Date, no event has occurred which should have been set forth in a
     supplement or amendment to the Prospectus which has not been set forth in
     such a supplement or amendment, (iii) since the respective dates as of
     which information is given in the Registration Statement in the form in
     which it originally became effective and the Prospectus contained therein,
     there has not been any material adverse change or any development involving
     a prospective material adverse change in or affecting the business,
     properties, financial condition or results of operations of the Company,
     whether or not arising from transactions in the ordinary course of
     business, and, since such dates, except in the ordinary course of business.
     The Company has not entered into any material transaction not referred to
     in the Registration Statement in the form in which it originally became
     effective and the Prospectus contained therein, (iv) the Company does not
     have any material contingent obligations which are not disclosed in the
     Registration Statement and the Prospectus, (v) there are not any pending or
     known threatened legal proceedings to which the Company is a party or of
     which property of the Company is the subject which are material and which
     are not disclosed in the Registration Statement and the Prospectus,
     (vi) there are not any franchises, contracts, leases or documents which are
     material which have not been filed as exhibits to the Registration
     Statement, (vii) the representations and warranties of the Company herein
     are true and correct in all material respects as of the Closing Date or any
     later date on which Option Stock is to be purchased, as the case may be,
     and (viii) there has not been any material change in the market for
     securities in general or in political, financial or economic conditions
     from those reasonably foreseeable as to render it impracticable in your
     reasonable judgment to make a public offering of the Stock, or a material
     adverse change in market levels for securities in general (or those of
     companies in particular) or financial or economic conditions which render
     it inadvisable to proceed.

(e)  You shall have received on the Closing Date and on any later date on which
     Option Stock is purchased a certificate, dated the Closing Date or such
     later date, as the case may be, and signed by the President and the Chief
     Financial Officer of the Company, stating that the respective signers of
     said certificate have carefully examined the Registration Statement in the
     form in which it originally became effective and the Prospectus contained
     therein and any supplements or amendments thereto, and that the statements
     included in clauses (i) through (vii) of paragraph (d) of this Section 9
     are true and correct.

(f)  You shall have received from Ernst & Young LLP a letter or letters
     addressed to the Underwriters and dated the Closing Date and any later date
     on which Option Stock is purchased, confirming that they are independent
     public accountants with respect to the Company within the meaning of the
     Securities Act and the applicable published rules and regulations
     thereunder and based upon the procedures described in their letter
     delivered to you concurrently with the execution of this Agreement (herein
     called the Original Letter), but carried out to a date not more than three
     business days prior to the Closing Date or such later date on which Option
     Stock is purchased (i) confirming, to the extent true, that the statements
     and conclusions set forth in the Original Letter are accurate as of the
     Closing Date or such later date, as the case may be, and (ii) setting forth
     any revisions and additions to the statements and conclusions set forth in
     the Original Letter which are necessary to reflect any changes in the facts
     described in the Original Letter since the date of the Original Letter or
     to reflect the availability of more recent financial statements, data or
     information.  The letters shall not disclose any change, or any development
     involving a prospective change, in or affecting the business or properties
     of the Company (or any of its subsidiaries) which, in your sole judgment,
     makes it impractical or inadvisable to proceed with the public offering of
     the Stock or the purchase of the Option Stock as contemplated by the
     Prospectus.

(g)  You shall have received from Ernst & Young LLP a letter stating that 
     their review of the Company's system of internal accounting controls, to 
     the extent they deemed necessary in establishing the scope of their 
     examination of the Company's financial statements as at March 31, 1999, 
     did not disclose any weakness in internal controls that they considered 
     to be material weaknesses.

                                      14



(h)  You shall have been furnished evidence in usual written or telegraphic form

     shall have been duly authorized for listing by the Nasdaq National Market
     upon official notice of issuance.

(j)  On or prior to the Closing Date, you shall have received from all
     stockholders agreements, in form reasonably satisfactory to Hambrecht &
     Quist LLC, stating that without the prior written consent of Hambrecht &
     Quist LLC on behalf of the Underwriters, that each such person or entity
     will not, for a period of 180 days following the commencement of the public
     offering of the Stock by the Underwriters, directly or indirectly, sell,
     lend, offer, contract to sell, transfer the economic risk of ownership in,
     make any short sale, pledge, or otherwise dispose of any shares of Common
     Stock of the Company acquired prior to the Effective Date, or any
     securities acquired prior to the Effective Date that are convertible into
     or exchangeable or exercisable for or any othre rights to purchase or
     acquire Common Stock of the Company. 

(k)  All the agreements, opinions, certificates and letters mentioned above or
     elsewhere in this Agreement shall be deemed to be in compliance with the
     provisions hereof only if Gunderson Dettmer Stough Villeneuve Franklin &

     comply in form and scope.

          In case any of the conditions specified in this Section 9 shall not be
     fulfilled, this Agreement may be terminated by you by giving notice to the
     Company.  Any such termination shall be without liability of the Company to
     the Underwriters and without liability of the Underwriters to the Company;
     PROVIDED, HOWEVER, that (i) in the event of such termination, the Company
     agrees to indemnify and hold harmless the Underwriters from all costs or
     expenses incident to the performance of the obligations of the Company
     under this Agreement, including all costs and expenses referred to in
     paragraphs (i) and (j) of Section 6 hereof, and (ii) if this Agreement is
     terminated by you because of any refusal, inability or failure on the part
     of the Company to perform any agreement herein, to fulfill any of the
     conditions herein, or to comply with any provision hereof other than by
     reason of a default by any of the Underwriters, the Company will reimburse
     the Underwriters severally upon demand for all out-of-pocket expenses
     (including reasonable fees and disbursements of counsel) that shall have
     been incurred by them in connection with the transactions contemplated
     hereby.

          10.  CONDITIONS OF THE OBLIGATION OF THE COMPANY.  The obligation of

     order suspending the effectiveness thereof shall be in effect and no
     proceedings therefor shall be pending or threatened by the Commission.

     notice to you. Any such termination shall be without liability of the
     Company to the Underwriters and without liability of the Underwriters to
     the Company; PROVIDED, HOWEVER, that in the event of any such termination
     the Company agrees to indemnify and hold harmless the Underwriters from all
     costs or expenses incident to the performance of the obligations of the
     Company under this Agreement, including all costs and expenses referred to
     in paragraphs (i) and (j) of Section 6 hereof.

          11.  REIMBURSEMENT OF CERTAIN EXPENSES.  In addition to its other

     and other expenses incurred in connection with investigating or defending
     any claim, action, investigation, inquiry or other proceeding arising out
     of or based upon any statement or omission, or any alleged statement or
     omission, described in paragraph (a) of Section 7 of this Agreement,
     notwithstanding the absence of a judicial determination as to the propriety
     and enforceability of the obligations under this Section 11 and the
     possibility that such payments might later be held to be improper;
     PROVIDED, HOWEVER, that (i) to the extent any such payment is ultimately
     held to be improper, the persons receiving such payments shall promptly
     refund them and (ii) such persons shall provide to the Company, upon
     request, reasonable assurances of their ability to effect any refund, when
     and if due.

                                      15

             MATTERS TO BE COVERED IN THE OPINION OF FENWICK & WEST LLP
                              COUNSEL FOR THE COMPANY


     (i)    The Company has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the State of Delaware, to our
knowledge is duly qualified to do business as a foreign corporation and in good
standing in each state of the United States of America in which its ownership or
leasing of property requires such qualification (except where the failure to be
so qualified would not have a material adverse effect on the business,
properties, financial condition or results of operations of the Company), and
has full corporate power and corporate authority to own or lease its properties
and conduct its current business as described in the Registration Statement; 

     (ii)   as of the closing of the sale of the Underwritten Stock and assuming
the filing of the Second Amended and Restated Certificate of Incorporation with
the Secretary of State of the State of Delaware, the authorized capital stock of
the Company consists of  5,000,000 shares of Preferred Stock, $0.001 pare value,
of which, to our knowledge, there are no shares outstanding, and 100,000,000
shares of Common Stock, $0.001 par value, of which, to our knowledge there are
outstanding _________________ shares (including the Underwritten Stock issued on
the date hereof); proper corporate proceedings have been taken validly to
authorize such authorized capital stock; all of the outstanding shares of such
capital stock (including the Underwritten Stock) have been duly and validly
issued and are fully paid and nonassessable; and, except as described in the
Prospectus, no preemptive rights of, or rights of refusal in favor of,
stockholders of the Company exist with respect to the Stock, or the issue and
sale thereof, pursuant to the First Amended and Restated Certificate of
Incorporation or Bylaws of the Company;

     (iii)  the Registration Statement has become effective under the Securities
Act and, to the best of such counsel's knowledge, no stop order suspending the
effectiveness of the Registration Statement or suspending or preventing the use
of the Prospectus is in effect and no proceedings for that purpose have been
instituted or are pending or contemplated by the Commission;

     (iv)   the Registration Statement and the Prospectus (except as to the
financial statements and schedules and other financial and statistical data
contained therein, as to which such counsel need express no opinion) comply as
to form in all material respects with the requirements of the Securities Act,
the Exchange Act and with the rules and regulations of the Commission
thereunder;

     (v)    the information required to be set forth in the Registration
Statement in answer to Items 9, 10 (insofar as it relates to such counsel) and
11(c) of Form S-1, to such counsel's knowledge, is accurately and adequately set
forth in the Registration Statement in all material respects or no response is
required with respect to such Items, and the description of the Company's stock
option plans and the options granted and which may be granted thereunder and the
options granted otherwise than under such plans set forth in the Prospectus, to

     Counsel rendering the foregoing opinion will also state that although such
counsel has not independently verified the accuracy or completeness of the
statements made in the Registration Statement or the Prospectus, such counsel
had no reason to believe that the Registration Statement (except as to the
financial statements and schedules and other financial and statistical data
contained or incorporated by reference therein, as to which such counsel need
not express any belief) at the 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 that the
Prospectus (except as to the financial statements and schedules and other
financial and statistical data contained or incorporated by reference therein,
as to which such counsel need not express any belief) as of its date or at the
Closing Date, contained or contains any untrue statement of a material fact or
omitted or omits to state any material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading; PROVIDED, HOWEVER, that none of the statements of belief in this
paragraph shall apply to statements in, or omissions from, the Registration
Statement or the Prospectus made in reliance upon and in conformity with
information herein or otherwise furnished in writing to the Company by or on
behalf of the Underwriters for use in the Registration Statement or the
Prospectus.

     Counsel rendering the foregoing opinion may rely as to questions of law not
involving the laws of the United States or of the State of California, upon
opinions of local counsel satisfactory in form and scope to counsel for the
Underwriters.  Copies of any opinions so relied upon shall be delivered to the
Representatives and to counsel for the Underwriters and the foregoing opinion
shall also state that counsel knows of no reason the Underwriters are not
entitled to rely upon the opinions of such local counsel.
