Ladies and Gentlemen:

         Cybermedia, Inc., a Delaware corporation (herein called the Company),
proposes to issue and sell * shares of its authorized but unissued Common Stock,
$.01 par value (herein called the Common Stock) (said * shares of Common Stock
being herein called the Underwritten Stock). The Company proposes to grant to
the Underwriters (as hereinafter defined) an option to purchase up to *
additional shares of Common Stock (herein called the Option Stock and with the
Underwritten Stock herein collectively called the Stock). The Common Stock is
more fully described in the Registration Statement and the Prospectus
hereinafter mentioned.

         The Company hereby confirms the agreements made with respect to the
purchase of the Stock by the several underwriters, for whom you are acting,
named in Schedule I hereto (herein collectively called the Underwriters, which
term shall also include any underwriter purchasing Stock pursuant to Section
3(b) hereof). YOU represent and warrant that you have been authorized by each of
the other Underwriters to enter into this Agreement on its behalf and to act for
it in the manner herein provided.

         1. REGISTRATION STATEMENT. The Company has filed with the Securities
and Exchange Commission (herein called the Commission) a registration statement
on Form S-1 (No. 333-____), including the related preliminary prospectus, for
the registration under the Securities Act of 1933, as amended (herein called the
Securities Act) of the Stock. Copies of such registration statement and of each
amendment thereto, if any, including the related preliminary prospectus (meeting
the requirements of Rule 430A of the rules and regulations of the Commission)
heretofore filed by the Company with the Commission have been delivered to you.

         The term Registration Statement as used in this Agreement shall mean
such registration statement, including all exhibits and financial statements,
all information omitted therefrom in reliance upon Rule 430A and contained in
the Prospectus referred to below, in the form in which it became effective, and
any registration statement filed pursuant to Rule 462(b) of the rules and
regulations of the Commission with respect to the Stock (herein called a Rule

    cover over-allotments.

registration statement), and, in the event of any amendment thereto after
the effective date of such registration statement (herein called the Effective
Date), shall also mean (from and after the effectiveness of such amendment) such
registration statement as so amended (including any Rule 462(b) registration
statement). The term Prospectus as used in this Agreement shall mean the
prospectus relating to the Stock first filed with the Commission pursuant to
Rule 424(b) and Rule 430A (or if no such filing is required, as included in the
Registration Statement) and, in the event of any supplement or amendment to such
prospectus after the Effective Date, shall also mean (from and after the filing
with the Commission of such supplement or the effectiveness of such amendment)
such prospectus as so supplemented or amended. The term Preliminary Prospectus
as used in this Agreement shall mean each preliminary prospectus included in
such registration statement prior to the time it becomes effective.

         The Registration Statement has been declared effective under the
Securities Act, and no post-effective amendment to the Registration Statement
has been filed as of the date of this Agreement. The Company has caused to be
delivered to you copies of each Preliminary Prospectus and has consented to the
use of such copies for the purposes permitted by the Securities Act.

         2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby
represents and warrants as follows:

                  (i) The Company has been duly incorporated and is validly

         described in the Registration Statement and the Prospectus and as being
         conducted, and is duly qualified as a foreign corporation and in good
         standing in all jurisdictions in which the character of the property
         owned or leased or the nature of the business transacted by it makes
         qualification necessary (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 its
         subsidiaries, taken as a whole).

                  (ii) Since the respective dates as of which information is
         given in the Registration Statement and the Prospectus, there has not
         been any materially adverse change in the business, properties,
         financial condition or results of operations of the Company, whether or
         not arising from transactions in the ordinary course of business, other
         than as set forth in the Registration Statement and the Prospectus, and
         since such dates, except in the ordinary course of business, the
         Company has not entered into any material transaction not referred to

         state any material fact required to be stated therein or necessary in
         order to make the statements therein not misleading; and, on the

         therein, in the light of the circumstances under which they were made,
         not misleading; provided, however, that none of the representations and
         warranties in this subparagraph (iii) 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

         Board of Directors of the Company will be required for the issuance and
         sale of the Stock as contemplated herein.

                  (v) Prior to the Closing Date the Stock to be issued and sold

         to all real property and good and marketable title to all personal
         property owned by it, in each case free and clear of all liens,
         encumbrances and defects except such as are described in the Prospectus
         or such as do not materially affect the value of such property and do
         not interfere with the use made and proposed to be made of such
         property by the Company; and any real property and buildings held under
         lease by the Company are held by it under valid, subsisting and
         enforceable leases with such exceptions as are not material and do not
         interfere with the use made and proposed to be made of such property
         and buildings by the Company.

                  (vii) The Company has an authorized capitalization as set
         forth in the Prospectus, and all of the issued shares of capital stock
         of the Company have been duly and validly authorized and issued, are
         fully paid and non-assessable and conform to the description of the
         Stock contained in the Prospectus.

                  (viii) The issue and sale of the Stock to be sold by the
         Company and the compliance by the Company with all of the provisions of
         this Agreement and the consummation of the transactions herein
         contemplated will not conflict with or result in a breach or violation
         of any of the terms or provisions of, or constitute a default under,
         any indenture, mortgage, deed of trust, loan agreement or other
         agreement or instrument to which the Company is a party or by which the
         Company is bound or to which any of the property or assets of the
         Company is subject, nor will such action result in any violation of the
         provisions of the Certificate of Incorporation or Bylaws of the Company
         or any statute or any order, rule or regulation of any court or
         governmental agency or body having jurisdiction over the Company or any
         of its properties; and no consent, approval, authorization, order,
         registration or qualification of or with any such court or governmental
         agency or body is required for the issue and sale of the Stock or the
         consummation by the Company of the transactions contemplated by this
         Agreement, except the registration under the Act of the Stock and such
         consents, approvals, authorizations, registrations or qualifications as
         may be required under state securities or Blue Sky laws in connection
         with the purchase and distribution of the Stock by the Underwriters.

                  (ix) The Company is not in violation of its Certificate of
         Incorporation or Bylaws or in default in the performance or observance
         of any material obligation, agreement, covenant or condition contained
         in any indenture, mortgage, deed of trust, loan agreement, lease or
         other agreement or instrument to which it is a party or by which it or
         any of its properties may be bound.

                  (x) The statements set forth in the Prospectus under the
         caption "Description of Capital Stock", insofar as they purport to
         constitute a summary of the terms of the Stock and under the caption
         "Underwriting", insofar as they purport to describe the provisions of
         the laws and documents referred to therein, are accurate, complete and
         fair.

                  (xi) Other than as set forth in the Prospectus, there are no
         legal or governmental proceedings pending to which the Company is a
         party or of which any property of the Company is the subject which, if
         determined adversely to the Company, would individually or in the
         aggregate have a material adverse effect on the current or future
         consolidated financial position, stockholders' equity or results of
         operations of the Company; and, to the best of the Company's knowledge,
         no such proceedings are threatened or contemplated by governmental
         authorities or threatened by others.

                  (xii) The Company is not and, after giving effect to the
         offering and sale of the Stock, will not be an "investment company" or
         an entity "controlled" by an "investment company", as such terms are

         disclosed in the Prospectus, the Company has not received any notice of
         infringement of or conflict with (and the Company does not know of any
         such infringement of or conflict with) asserted rights of others with
         respect to any patents, trademarks, service marks, trade names,
         copyrights, technology or know-how which, singly or in the aggregate,
         would result in any material adverse effect upon the Company; and,
         except as disclosed in the Prospectus, the Company's discoveries,
         inventions, products or processes referred to in the Prospectus do not,
         to the Company's knowledge, infringe or conflict with any right or
         patent of any third party or any discovery, invention, product or
         process which is the subject of a patent application filed by any third
         party known to the Company.

         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 1. 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. 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 1.

         (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 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

                                        4
   5
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 days preceding the Closing Date), and payment therefor, shall be made
at the office of ______________, at 7:00 a.m., San Francisco time, on the
fourth(2) 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 

- -------- 
(2) This assumes that the transaction will be priced after the close of market
    and that T+4 will apply to the transaction. If the pricing took place before
    or during market hours (which will generally not be the case), the closing
    would be three business days after pricing.

                                        5
   6
Stock, and payment therefor, shall be made at the office of ____________, 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 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 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 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 it 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 signed 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 signed 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 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.

   7
                  (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 (including, but not
         limited to, the Report on Form SR required by Rule 463 of the
         Commission under the Securities Act).

                  (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 II
         (a) of the Securities Act and Rule 158 thereunder.

                  (i) The Company agrees to pay all costs and expenses incident
         to the performance of its obligations under this Agreement, including
         all costs and expenses incident to (i) the preparation, printing and
         filing with the Commission and the National Association of Securities
         Dealers, Inc. 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

                                       7
   8
         in 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
         NASD.

                  (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 commencement
         of the public offering of the Stock by the Underwriters, 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 granted
         under the stock option plans of the Company (the "Option Plans") or
         upon the exercise of warrants outstanding as of the date hereof, all as
         described under the caption "Capitalization" in the Preliminary
         Prospectus, and (C) options to purchase Common Stock granted under the
         Option Plans.

                  (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.

         7.       INDEMNIFICATION AND CONTRIBUTION.

         (a) 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 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 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

                                        8
   9
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 provisions 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 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 

                                        9
   10
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 and the Underwriters 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.

         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 

                                       10
   11
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, The Nasdaq National 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 or 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 its obligations to be performed hereunder at
or prior to the Closing Date or any later date on 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 Brobeck,
         Phleger & Harrison LLP, counsel for the Underwriters.

                  (c) You shall have received from Wilson, Sonsini, Goodrich &
         Rosati, a Professional corporation, 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 purchased at any date after the Closing Date, additional opinions
         from such counsel, addressed to the Underwriters and dated such later
         date, confirming that the statements expressed as of the Closing Date
         in such opinions remain valid as of such later date.

                                       11
   12

                  (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 other documents which are required
         to be filed as exhibits to the Registration Statement which have not
         been filed as required, (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 KPMG Peat Marwick 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 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 KPMG Peat Marwick 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 December 31, 1995, did not disclose any weakness in
         internal controls that they considered to be material weaknesses.

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

                                       12
   13
         appropriate authorities of the several jurisdictions, or other evidence
         satisfactory to you, of the qualification referred to in paragraph (f)
         of Section 6 hereof.

                  (i) Prior to the Closing Date, the Stock to be issued and sold
         by the Company 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 directors, officers, and beneficial holders of more than 5% of
         the outstanding Common Stock 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,
         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, (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.

         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 Brobeck, Phleger & Harrison LLP, counsel for the
Underwriters, shall be satisfied that they 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.

be fulfilled, this Agreement may be terminated by the Company by giving 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.

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 

                                       13

respect to the provisions of Section 7 hereof, the several parties (in addition
to the Company and the several Underwriters) indemnified under the provisions of
said Section 7, and their respective personal representatives, successors and
assigns. Nothing in this Agreement is intended or shall be construed to give to
any other person, firm or corporation any legal or equitable remedy or claim
under or in respect of this Agreement or any provision herein contained. The

         jurisdiction of its incorporation, is duly qualified 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

         have a material adverse effect on the business, properties, financial
         condition or results of operations of the Company, and has full

         fully paid and nonassessable; and no preemptive rights of, or rights of

         make the statements therein, in light of the circumstances under which
         they were made, not misleading;
