Dear Sirs and Madams:

     COMPS.COM, Inc., a Delaware corporation (the "Company"), proposes to issue
and sell 3,800,000 shares  (the "Firm Shares") of its authorized but unissued

stockholders of the Company named in Schedule II hereto (collectively, the
"Selling Securityholders") propose to grant to the Underwriters (as defined

(the "Optional Shares" and, with the Firm Shares, collectively, the "Shares").
The Common Stock is more fully described in the Registration Statement and the
Prospectus hereinafter mentioned.  Christopher A. Crane is also hereinafter
referred to as the "Principal Securityholder."

     The Company and the Selling Securityholders severally hereby confirm the
agreements made with respect to the purchase of the Shares by the several
underwriters, for whom you are acting, named in Schedule I hereto (collectively,
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/ Plus an option to purchase from the Company up to 285,000 additional shares
and from the Selling Securityholders up to 285,000 additional shares to cover
over-allotments.

 
     Section 1.  Representations and Warranties of the Company and the Principal
Securityholder. The Company and the Principal Securityholder hereby represent
and warrant to the several Underwriters as of the date hereof and as of each
Closing Date (as defined below) that:

          (a) The Company has filed with the Securities and Exchange Commission
(the "Commission") a registration statement on Form S-1 (No. 333-72901),
including the related preliminary prospectus, for the registration under the
Securities Act of 1933, as amended (the "Securities Act") of the Shares.  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 shares (a "Rule 462(b)
registration statement"), and, in the event of any amendment thereto after the
effective date of such registration statement (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 Shares 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.

        (b) The Company has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the State of Delaware, has full
corporate power and authority to own or lease its properties and conduct its
business as 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, condition (financial or otherwise)
or results of operations of the Company.

                                       2

 
        (c) The Company does not own or control, directly or indirectly, any
corporation, association or other entity.  The Company is in possession of, and
operating in compliance with, all material authorizations, licenses, permits,
consents, certificates and orders material to the conduct of its respective
businesses as described in the Prospectus, all of which are valid and in full
force and effect.

        (d) 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, condition (financial or otherwise)
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 in the Registration Statement and the Prospectus.

        (e) The Registration Statement and the Prospectus comply, and on the
Closing Date (as hereinafter defined) and any later date on which Optional
Shares are to be purchased, the Prospectus will comply, in all material
respects, with the provisions of the Securities Act and the rules and
regulations of the Commission thereunder; on the Effective Date, the
Registration Statement did not contain any untrue statement of a material fact
and did not omit to state any material fact required to be stated therein or
necessary in order to make the statements therein not misleading; and, on the
Effective Date the Prospectus did not and, on the Closing Date and any later
date on which Optional Shares are to be purchased, 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 under
which they were made, not misleading; provided, however, that none of the
representations and warranties in this subparagraph (e) 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.

        (f) The Company has authorized and outstanding capital stock as set
forth under the heading "Capitalization" in the Prospectus.  The issued and
outstanding shares of Common Stock have been duly authorized and validly issued,
are fully paid and nonassessable, have been issued in compliance with all
federal and state securities laws, and were not issued in violation of or
subject to any preemptive rights or other rights to subscribe for or purchase
securities.  Except as disclosed in or contemplated by the Prospectus and the
financial statements of the Company and the related notes thereto included in
the Prospectus, the Company has no outstanding options to purchase, or any
preemptive rights or other rights to subscribe for or to purchase, any
securities or obligations convertible into, or any contracts or commitments to
issue or sell, shares of its capital stock or any such options, rights,
convertible securities or obligations.  The description of the Company's stock
option, stock bonus and other stock plans or arrangements, and the options or
other rights granted and exercised thereunder, set forth in the Prospectus
accurately and fairly presents the information required by the Securities Act
and the rules and regulations to be shown with respect to such plans,
arrangements, options and rights.

                                       3

 
        (g) The Shares are duly authorized, are (or, in the case of Shares to be
sold by the Company, will be, when issued and sold to the Underwriters as
provided herein) validly issued, fully paid and nonassessable and conform to the
description thereof in the Prospectus.  No further approval or authority of the
stockholders or the Board of Directors of the Company will be required for the
transfer and sale of the Shares to be sold by the Selling Stockholders or the
issuance and sale of the Shares to be sold by the Company as contemplated
herein.

        (h) The Shares are authorized for listing on the Nasdaq National Market
upon official notice of issuance.

        (i) The Shares to be sold by the Company will be sold free and clear of
any pledge, lien, security interest, encumbrance, claim or equitable interest,
and will conform to the description thereof contained in the Prospectus.  No
preemptive right, co-sale right, registration right, right of first refusal or
other similar right to subscribe for or purchase securities of the Company
exists with respect to the issuance and sale of the Shares by the Company
pursuant to this Agreement.  No stockholder of the Company has any right which
has not been waived, or complied with, to require the Company to register the
sale of any shares owned by such stockholder under the Securities Act in the
public offering contemplated by this Agreement.

        (j) The Company has full corporate power and authority to enter into
this Agreement and perform the transactions contemplated hereby.  This Agreement
has been duly authorized, executed and delivered by the Company and constitutes
a valid and binding obligation of the Company. The making and performance of
this Agreement by the Company and the consummation of the transactions
contemplated hereby (i) will not violate any provisions of the second restated
certificate of incorporation of the Company (the "Certificate of
Incorporation"), the restated bylaws of the Company (the "Bylaws") or other
organizational documents of the Company, and (ii) will not conflict with, result
in a material breach or violation of, or constitute, either by itself or upon
notice or the passage of time or both, a material default under (A) any
agreement, mortgage, deed of trust, lease, franchise, license, indenture, permit
or other instrument to which the Company is a party or by which the Company or
any of its properties may be bound or affected, or (B) any statute or any
authorization, judgment, decree, order, rule or regulation of any court or any
regulatory body, administrative agency or other governmental body applicable to
the Company or any of its properties. No consent, approval, authorization or
other order of any court, regulatory body, administrative agency or other
governmental body that has not already been obtained is required for the
execution and delivery of this Agreement or the consummation of the transactions
contemplated by this Agreement, except for compliance with the Securities Act,
the Blue Sky laws applicable to the public offering of the Common Shares by the
several Underwriters and the clearance of such offering with the NASD.

                                       4

 
        (k) The financial statements and schedules of the Company and REALBID,
LLC, a California limited liability company ("REALBID") and the related notes
thereto included in the Registration Statement and the Prospectus present fairly
the financial position of the Company and REALBID, respectively as of the
respective dates of such financial statements and schedules, and the results of
operations and cash flows of the Company and REALBID, respectively for the
respective periods covered thereby.  Such statements, schedules and related
notes have been prepared in accordance with generally accepted accounting
principles applied on a consistent basis throughout the periods specified, as
certified by the independent accountants named in subsection 10(g).  No other
financial statements or schedules are required to be included in the
Registration Statement.  The selected financial data set forth in the Prospectus
under the captions "Capitalization" and "Selected Financial Data" fairly present
the information set forth therein on the basis stated in the Registration
Statement.

        (l) The Company maintains a system of internal accounting controls
sufficient to provide reasonable assurances that (i) transactions are executed
in accordance with management's general or specific authorizations, (ii)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles and to
maintain accountability for assets, (iii) access to assets is permitted only in
accordance with management's general or specific authorization, and (iv) the

reasonable intervals and appropriate action is taken with respect to any
differences.  The representations and warranties given by the Company and its
officers to its independent public accountants for the purpose of supporting the
letters referred to in Section 10(f) are true and correct.

        (m) The Company is not (i) in violation or default of any provision of
its Certificate of Incorporation, Bylaws or other organizational documents, or
(ii) in a material breach of or default with respect to any provision of any
agreement, judgment, decree, order, mortgage, deed of trust, lease, franchise,
license, indenture, permit or other instrument to which it is a party or by
which it or any of its properties are bound; and there does not exist any state
of facts which, with notice or lapse of time or both would constitute such a
breach or default on the part of the Company.

        (n) There are no contracts or other documents required to be described
in the Registration Statement or to be filed as exhibits to the Registration
Statement by the Securities Act or by the Rules and Regulations which have not
been described or filed as required.  The contracts so described in the
Prospectus are in full force and effect on the date hereof.

        (o) Except as disclosed in the Prospectus, there are no legal or
governmental actions, suits or proceedings pending or, to the knowledge of the

is, to the knowledge of the Company or the Principal Securityholder, threatened
to be made the subject, which actions, suits or proceedings could, individually
or in the aggregate, prevent or adversely affect the transactions contemplated
by this Agreement or result in a material adverse change in the business,
properties, condition (financial or otherwise), or results of operations of the
Company; 

                                       5

 
and no labor disturbance by the employees of the Company exists or is imminent
which could materially adversely affect the business, properties, condition
(financial or otherwise), or results of operations of the Company. The Company
is not a party or subject to the provisions of any material injunction,
judgment, decree or order of any court, regulatory body, administrative agency
or other governmental body. Except as disclosed in the Prospectus, there are no
material legal or governmental actions, suits or proceedings pending or, to the
Company's or the Principal Securityholder's knowledge, threatened against any
executive officers or directors of the Company.

        (p) The Company has good and marketable title to all the properties and
assets reflected as owned in the financial statements hereinabove described (or
elsewhere in the Prospectus), subject to no lien, mortgage, pledge, charge or
encumbrance of any kind except (i) those, if any, reflected in such financial
statements (or elsewhere in the Prospectus), or (ii) those which are not
material in amount to the Company and do not adversely affect the use made and
proposed to be made of such property by the Company.  The Company holds its
leased properties under valid and binding leases.  Except as disclosed in the
Prospectus, the Company owns or leases all such properties as are necessary to
its operations as now conducted or as proposed to be conducted.

        (q) Since the respective dates as of which information is given in the
Registration Statement and Prospectus, and except as described in or
specifically contemplated by the Prospectus:  (i) the Company has not (A)
incurred any liabilities or obligations, indirect, direct or contingent, or (B)
entered into any oral or written agreement or other transaction, which in the

businesses or properties from fire, flood, windstorm, accident or other
calamity, whether or not covered by insurance;  (iii) the Company has not paid
or declared any dividends or other distributions with respect to its capital
stock and the Company is not in default in the payment of principal or interest
on any outstanding debt obligations;  (iv) there has not been any change in the
capital stock of the Company (other than upon the sale of the Shares hereunder
or upon the exercise of any options or warrants disclosed in the Prospectus);
(v) there has not been any material increase in the short- or long-term debt of
the Company; and (vi) there has not been any material adverse change or any
development involving or which may reasonably be expected to involve a
prospective material adverse change, in the business, condition (financial or
otherwise), properties, or results of operations of the Company.

        (r) The Company is conducting business in compliance with all applicable
laws, rules and regulations of the jurisdictions in which it is conducting
business,  except where the failure to be so in compliance would not have a
material adverse effect on the business, business prospects, properties,
condition (financial or otherwise) or results of operations of the Company.

        (s) The Company has filed all necessary federal, state and foreign
income and franchise tax returns, and all such tax returns are complete and
correct in all material respects, and the Company has not failed to pay any
taxes which were payable pursuant to said returns or any assessments with
respect thereto.  Neither the Company nor the Principal Securityholder has any
knowledge of any tax deficiency which has been or is likely to be threatened or
asserted against the 

                                       6

 
Company.

        (t) The Company has not distributed, and will not distribute prior to
the later to occur of (i) completion of the distribution of the Shares, or (ii)

directors' and officers' insurance, insurance covering real and personal
property owned or leased by the Company against theft, damage, destruction,
acts of vandalism and all other risks customarily insured against, all of which
insurance is in full force and effect.  The Company has not been refused any
insurance coverage sought or applied for, and the Company has no reason to
believe that it will not be able to renew its existing insurance coverage as and
when such coverage expires or to obtain similar coverage from similar insurers
as may be necessary to continue its business at a cost that would not materially
adversely affect the business, properties, condition (financial or otherwise) or
results of operations of the Company.

        (v) Neither the Company nor, to the best of the Company's or the
Principal Securityholder's knowledge, any of its employees or agents has at any
time during the last five years (i) made any unlawful contribution to any
candidate for foreign office, or failed to disclose fully any contribution in
violation of law, or (ii) made any payment to any foreign, federal or state
governmental officer or official or other person charged with similar public or
quasi-public duties, other than payments required or permitted by the laws of
the United States or any jurisdiction thereof.

        (w) The Company has not taken and will not take, directly or indirectly,

in stabilization or manipulation of the price of the Common Stock to facilitate

purchase or acquire, Common Stock (including, without limitation, Common Stock
which may be deemed to be beneficially owned in accordance with the rules and
regulations of the 

                                       7

 
Commission) other than the exercise or conversion of outstanding options,
warrants or convertible securities; or (ii) enter into any swap or other
agreement that transfers, in whole or in part, any of the economic consequences

        (aa) Except as specifically disclosed in the Prospectus, the Company has
sufficient trademarks, trade names, patent rights, copyrights, licenses,
approvals and governmental authorizations to conduct its businesses as now
conducted; the expiration of any trademarks, trade names, patent rights,
copyrights, licenses, approvals or governmental authorizations would not have a
material adverse effect on the business, properties, condition (financial or
otherwise) or results of operations of the Company; neither the Company nor the
Principal Securityholder has any knowledge of any infringement by the Company of
trademark, trade name rights, patent rights, copyrights, licenses, trade secret
or other similar rights of others; and no claims have been made or, to the
Company's or the Principal Securityholder's knowledge, are threatened against

        Section 2.  Representations and Warranties, and Covenants, of the
Selling Securityholders.

        Each of the Selling Securityholders, severally and not jointly,
represents and warrants and covenants to the several Underwriters as of the date
hereof and as of each date on which Optional Shares are purchased that:

        (a) Such Selling Securityholder has reviewed the representations and
warranties of the Company and, although such Selling Securityholder has not
independently verified the accuracy of such representations and warranties, such
Selling Securityholder has no reason to believe that such representations and
warranties of the Company contained in Section 1 are not true and correct in all
respects.

        (b) Such Selling Securityholder is the sole owner of the Shares to be
sold by such Selling Securityholder hereunder, free and clear of all liens,
encumbrances, equities, security interests and claims whatsoever, with full
right and authority to deliver the same hereunder, subject, in the case of each
Selling Securityholder, to the rights of _____________ , as Custodian (the
"Custodian"), and that upon the delivery of and payment for such Shares
hereunder, the several Underwriters will receive valid title thereto, free and
clear of all liens, encumbrances, equities, security interests and claims
whatsoever.

        (c) Certificates in negotiable form for the Shares to be sold by such
Selling Securityholder have been placed in custody under a Custody Agreement for
delivery under this Agreement with the Custodian; such Selling Securityholder
specifically agrees that the Shares represented by the certificates so held in
custody for such Selling Securityholder are subject to the interests of the
several Underwriters and the Company, that the arrangements made by such Selling
Securityholder for such custody, including the Power of Attorney provided for in
such Custody Agreement, are to that extent irrevocable, and that the obligations
of such Selling Securityholder shall not be terminated by any act of such
Selling Securityholder or by operation of law, whether by the death or
incapacity of such Selling Securityholder (or, in the case of a Selling
Securityholder that is not an individual, the dissolution or liquidation of such
Selling Securityholder) or the occurrence of any other event; if any such death,
incapacity, dissolution, liquidation or other such event should occur before the
delivery of such shares of the shares hereunder, certificates for the Shares
shall be delivered by the Custodian in accordance with the terms and conditions
of this Agreement as if such death, incapacity, dissolution, liquidation or
other event had not occurred, regardless of whether the Custodian shall have
received notice of such death, incapacity, dissolution, liquidation or other
event.

        (d) Such Selling Securityholder has reviewed the Registration Statement
and Prospectus and, although such Selling Securityholder has not independently
verified the accuracy or completeness of all the information contained therein,
nothing has come to the attention of such Selling Securityholder that would lead
such Selling Securityholder to believe that (i) on the Effective Date, the

                                       9

 
Registration Statement contained any untrue statement of a material fact or
omitted to state any material fact required to be stated therein or necessary in
order to make the statements therein not misleading; and, (ii) on the Effective
Date the Prospectus contained and, on the Closing Date and any later date on
which Optional Shares are to be purchased 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 the light of the circumstances under which
they were made, not misleading.

        (e) All information in the Registration Statement or the Prospectus, or
any amendment or supplement thereto, relating to such Selling Securityholder
which is set forth in the Prospectus under the caption "Management", "Certain
Relationships and Related Transactions" and "Principal and Selling
Stockholders," (the "Selling Securityholder Information") and all
representations and warranties of such Selling Securityholder in the Custody
Agreement are true and correct in all respects and do not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the information in the light of the
circumstances under which they were made not misleading. The sale of the Shares
by such Selling Securityholder pursuant hereto is not prompted by such Selling
Securityholder's knowledge of any material information concerning the Company
which is not set forth in the Prospectus.

        (f) Such Selling Securityholder has full power and authority to enter
into this Agreement and the Custody Agreement and perform the transactions
contemplated hereby and thereby.  This Agreement and the Custody Agreement have
been duly authorized, executed and delivered by or on behalf of such Selling
Securityholder and the form of such Securityholder Agreement has been delivered
to you.

        (g) The making and performance of this Agreement and the Custody
Agreement and the consummation of the transactions contemplated hereby and
thereby will not result in a breach or violation by such Selling Securityholder
of any of the terms or provisions of, or constitute a default by such Selling
Securityholder under, any indenture, mortgage, deed of trust, trust
(constructive or other), loan agreement, lease, franchise, license or other
agreement or instrument to which such Selling Securityholder is a party or by
which such Selling Securityholder or any of its properties is bound, any
statute, or any judgment, decree, order, rule or regulation of any court or
governmental agency or body applicable to such Selling Securityholder or any of
its properties.

        (h) Such Selling Securityholder has not taken and will not take,
directly or indirectly, any action designed to or that might reasonably be
expected to cause or result in stabilization or manipulation of the price of any
security of the Company to facilitate the sale or resale of the Shares.

        (i) Each of the Selling Securityholders agrees that during the period of
one hundred and eighty (180) days after the date of the Registration Statement
becomes effective, without the prior written consent of Volpe Brown Whelan &
Company, L.L.C., such Selling Securityholder will not (i) offer, sell, make any
short sale (including without limitation short against the box), pledge or
otherwise dispose of, directly or indirectly, any of the Company's Common Stock,
options to acquire Common Stock or securities convertible into or exchangeable
for or any other rights to purchase or acquire the Company's Common Stock
(including without limitation, Common Stock of the Company which may 

                                       10

 
be deemed to be beneficially owned in accordance with the rules and regulations
of the Commission) other than the exercise or conversion of outstanding options,
warrants or convertible securities 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 (i) or
(ii) is to be settled by delivery of Common Stock or such other securities, in
cash or otherwise; provided, however, that bona fide gift transactions and
transfers which will not result in any change in beneficial ownership may be
permitted if the transferee enters into a lock-up agreement in substantially the
same form covering the remainder of the lock-up period.

        Notwithstanding the foregoing, it is understood and agreed by the
parties hereto that nothing in this Section 2 shall, in any way, limit the
representations and warranties and covenants of the Principal Securityholder
contained in Section 1 of this Agreement.

        Section 3.  Purchase of the Shares 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
the Firm Shares to the several Underwriters and each of the Underwriters agrees
to purchase from the Company the respective aggregate number of Firm Shares set
forth opposite its name in Schedule I.  The price at which such Firm Shares
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 Firm Shares which represents the same
proportion of the total number of Firm Shares to be sold by the Company pursuant
to this Agreement as the number of Firm Shares set forth opposite the name of
such Underwriter in Schedule I hereto represents of the total number of shares
of the Firm Shares to be purchased by all Underwriters pursuant to this
Agreement, as adjusted by you in such manner as you deem advisable to avoid
fractional shares.  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 Firm Shares 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 9 or 10 hereof) to purchase and
pay for the number of Shares 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 Shares 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 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 portion 

                                       11

 
which the defaulting Underwriter or Underwriters agreed to purchase if the
aggregate number of such Shares exceeds 10% of the total number of Shares which
all Underwriters agreed to purchase hereunder. If the total number of Shares
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 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 of the Shares 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 or the Selling
Securityholders to any non-defaulting Underwriter and without any liability on
the part of any non-defaulting Underwriter to the Company or the Selling
Securityholders.  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
and the Selling Securityholders grant an option to the several Underwriters to
purchase, severally and not jointly, up to 570,000 Optional Shares from the
Company and the Selling Securityholders at the same price per share as the
Underwriters shall pay for the Firm Shares.  Said option may be exercised only
to cover over-allotments in the sale of the Firm Shares by the Underwriters and
may be exercised in whole or in part at any time 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 Optional Shares as to which
the several Underwriters are exercising the option.  Delivery of certificates
for the Optional Shares, and payment therefor, shall be made as provided in
Section 5 hereof.  The number of Optional Shares to be purchased by each
Underwriter shall be the same percentage of the total number of Optional Shares
to be purchased by the several Underwriters as such Underwriter is purchasing of
the Firm Shares, as adjusted by you in such manner as you deem advisable to
avoid fractional shares.

        Section 4.  Offering by Underwriters.

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

        (b) The third paragraph and the list of underwriters on page 61 and the
last two paragraphs on page 62 constitute 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.

                                       12

 
        Section 5.  Delivery of and Payment for the Shares.

        (a) Delivery of certificates for the Firm Shares and the Optional Shares
(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 Brobeck, Phleger & Harrison LLP, 550 West C Street, Suite 1300, San Diego,
California 92101, 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, the Selling Securityholders 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 Optional Shares, and
payment therefor, shall be made at the office of Brobeck, Phleger & Harrison
LLP, 550 West C Street, Suite 1300, San Diego, California 92101, at 7:00 a.m.,
San Francisco time, on the third business day after the exercise of such option.

        (c) Payment for the shares purchased from the Company shall be made to
the Company or its order, and payment for the shares purchased from the Selling
Securityholders shall be made, in the discretion of the Underwriters, to them or
to the Custodian, for the account of the Selling Securityholders, in each case
by (i) one or more certified or official bank check or checks in next day funds
or (ii) federal funds wire transfer.  Such payment shall be made upon delivery
of certificates for the shares to you for the respective accounts of the several
Underwriters (including without limitation by "full-fast" electronic transfer by
Depository Trust Company) against receipt therefor signed by you.  Certificates
for the shares 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 Firm Shares, and at least one business
day prior to the purchase thereof, in the case of the Optional Shares.  Such
certificates will be made available to the Underwriters for inspection, checking
and packaging at the offices of agent of Volpe Brown Whelan & Company's clearing
agent, Bear Sterns Securities Corp., on the business day prior to the Closing
Date or, in the case of the Optional Shares, 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
and the Selling Securityholders 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 Optional Shares are purchased for the account of such Underwriter.
Any such payment by you shall not relieve such Underwriter from any of its
obligations hereunder.

        Section 6.  Covenants of the Company and the Selling Securityholders.
The Company and each of the Selling Securityholders covenants and agrees as
follows:

                                       13

 
        (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
shares 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 and
the Selling Securityholders 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.

        (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 shares,
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 shares by the Underwriters and during such period, the
Underwriters shall 

                                       14

 
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 shares 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 shares 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 shares 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 shares.

        (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 disclosure 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 11(a) of the Securities Act and Rule 158 thereunder.

        (i) For a period of one year commencing with the date hereof, the
Company agrees, at the Company's expense, to cause the Company's regularly
engaged independent certified public accountant to review (but not audit) the
Company's financial statements in accordance with the procedures specified by
the American Institute of Certified Public Accountants for a review of interim
financial information as described in Statement on Auditing Standards No. 71
"Interim Financial Information" for each of the three fiscal quarters prior to
the announcement of quarterly financial information, the filing of the Company's
Quarterly Report on Form 10-Q with the Commission and the mailing of quarterly
financial information to stockholders of the Company.

                                       15

 
        (j) The Company and the Selling Securityholders jointly and severally
agree to pay all costs and expenses incident to the performance of their
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. ("NASD") of the Registration Statement,
any Preliminary Prospectus and the Prospectus, (ii) the furnishing to the
Underwriters and the persons designated by them 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 paragraph (g) of this Section 6,
(vi) the printing and issuance of stock certificates, including the transfer
agent's fees and (vii) the fees incurred in connection with the listing of the
shares on the Nasdaq National Market.  The Selling Securityholders will pay any
transfer taxes incident to the transfer to the Underwriters of the Shares being
sold by the Selling Securityholders.

        (k) The Company and the Selling Securityholders jointly and severally
agree 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 shares under state
securities or blue sky laws and in the review of the offering by the NASD.

        (l) The provisions of paragraphs (j) and (k) of this Section are
intended to relieve the Underwriters from the payment of the expenses and costs
which the Company and the Selling Securityholders hereby agree to pay and shall
not affect any agreement which the Company and the Selling Securityholders may
make, or may have made, for the sharing of any such expenses and costs.

        (m) The Company and each of the Selling Securityholders hereby agree
that, without the prior written consent of Volpe Brown Whelan & Company L.L.C.,
the Company or such Selling Securityholder, as the case may be, will not, for a
period of 180 days following the date the Registration Statement becomes
effective, (i) offer, sell, contract to sell, make any short sale (including
without limitation short against the box), pledge, or otherwise dispose of,
directly or indirectly, any shares of Common Stock or any options to acquire
shares of Common Stock or securities convertible into or exchangeable or
exercisable for or any other rights to purchase or acquire Common Stock
(including without limitation, Common Stock of the Company which may be deemed
to be beneficially owned in accordance with the rules and regulations of the
Commission) other than the exercise or conversion of outstanding options,
warrants or convertible securities 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; provided, however, that bona fide gift
transactions and transfers which will not result in any change in beneficial
ownership may be permitted if the transferee enters into a lock-up agreement in
substantially the same form covering the remainder of the lock-up period.  The
foregoing sentence shall not apply to (A) the shares to be sold 

                                       16

 
to the Underwriters pursuant to this Agreement, (B) shares of Common Stock
issuable by the Company upon the exercise of warrants outstanding on the date
hereof, (C) options to purchase Common Stock granted or to be granted under the
Company's stock option plans, as described under the caption "Capitalization"
and "Management - 1999 Stock Incentive Plan" in the Preliminary Prospectus, (D)
shares of Common Stock purchased pursuant to the 1999 Employee Stock Purchase
Plan and (E) those options to purchase Common Stock listed on Schedule IV
attached hereto.

        (n)  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 reasonable
opinion the market price for the shares has been or is likely to be materially
affected (regardless of whether such rumor, publication or event necessitates a
supplement to or amendment of the Prospectus), the Company will, after written
notice from you advising the Company to the effect set forth above, forthwith
consult with you concerning disseminating a press release or other  public
statement commenting on such rumor, publication or event.

        (o)  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.

        (p)  The Company agrees to maintain directors' and officers' insurance
in amounts customary for the size and nature of the Company's business for a
period of two years from the date of this Agreement.

        Section 7.  Indemnification and Contribution.

        (a) Subject to the provisions of paragraph (f) of this Section 7, the
Company and the Selling Securityholders jointly and severally 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 (the "Exchange Act"), or the common law or otherwise,
and the Company and the Selling Securityholders jointly and severally 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 

                                       17

 
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 and the Selling Securityholders 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 Underwriter for use in any Preliminary Prospectus
or the Registration Statement or the Prospectus or any such amendment thereof or
supplement thereto, (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 shares 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, and (3) each Selling
Securityholder, other than the Principal Securityholder, shall only be liable
under this paragraph with respect to (A) information pertaining to such Selling
Securityholder furnished by or on behalf of such Selling Securityholder
expressly for use in any Preliminary Prospectus or the Registration Statement or
the Prospectus or any such amendment thereof or supplement thereto (it being
understood and agreed that the only information furnished by or on behalf of
each Selling Securityholder is the Selling Securityholder Information) or (B)
facts that would constitute a breach of any representation or warranty of such
Selling Securityholder set forth in Section 2 hereof. The indemnity agreements
of the Company and the Selling Securityholders contained in this paragraph (a)
and the representations and warranties of the Company and the Selling
Securityholders contained in Sections 1 and 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
shares.

        (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, and the Selling Securityholders 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 

                                       18

 
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 shares.

        (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 (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 (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 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 

                                       19

 
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 shares 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 Selling Securityholders 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 shares received by the Company and the Selling
Securityholders 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 shares. 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 shares purchased by such

                                       20

 
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 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) Neither the Company nor the Selling Securityholders will, 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.

        (f) The liability of each Selling Securityholder, other than the
Principal Securityholder, under such Selling Securityholder's representations
and warranties contained in paragraph (a) of Section 2 hereof and under the
indemnity and reimbursement agreements contained in the provisions of this
Section 7 and Section 8 hereof shall be limited to an amount equal to the total
net proceeds (before deducting expenses) received by such  Selling
Securityholder from the Underwriters for the sale of the Optional Shares sold by
such Selling Securityholder under the Registration Statement.  The Company and
the Selling Securityholders may agree, as among themselves and without limiting
the rights of the Underwriters under this Agreement, as to the respective
amounts of such liability for which they each shall be responsible.

        Section 8.  Reimbursement of Certain Expenses.  In addition to their
other obligations under Section 7 of this Agreement (and subject, in the case of
a Selling Securityholder other than the Principal Securityholder, to the
provisions of paragraph (f) of Section 7), the Company and the Selling
Securityholders hereby jointly and severally agree to reimburse on a monthly
basis the Underwriters for all reasonable legal 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 8 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 

                                       21

 
refund, when and if due.

        Section 9.  Termination.  This Agreement may be terminated by you at any
time prior to the Closing Date by giving written notice to the Company and the
Selling Securityholders in accordance with Section 10, or 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 or the Company's industry sector would, in the Underwriters'
reasonable judgment, make the offering or delivery of the shares 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 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 9, there shall be no liability of the Company or the Selling
Securityholders to the Underwriters and no liability of the Underwriters to the
Company or the Selling Securityholders; provided, however, that in the event of
any such termination the Company and the Selling Securityholders agree to
indemnify and hold harmless the Underwriters from all costs or expenses incident
to the performance of the obligations of the Company and the Selling
Securityholders under this Agreement, including all costs and expenses referred
to in paragraphs (j) and (k) of Section 6 hereof.

        Section 10.  Conditions of Underwriters' Obligations.  The obligations
of the several Underwriters to purchase and pay for the shares shall be subject
to the performance by the Company and by the Selling Securityholders of all
their respective obligations to be performed hereunder at or prior to the
Closing Date or any later date on which Optional Shares are 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 shares hereunder and
the validity and form of the certificates representing the shares, all corporate
proceedings and other legal matters incident to the foregoing, and the form of
the Registration Statement and of the Prospectus (except as 

                                       22

 
to the financial statements contained therein), shall have been approved at or
prior to the Closing Date by Katten Muchin & Zavis, counsel for the
Underwriters.

        (c) You shall have received from Brobeck, Phleger & Harrison 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 Optional
Shares are 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.

        (d) If Optional Shares are purchased on the Closing Date, you shall have
received from Gray Cary Ware Freidenrich LLP, counsel for the Selling
Securityholders, an opinion, addressed to the Underwriters and dated the Closing
Date, covering the matters set forth in Annex B hereto, and if Optional Shares
are 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.

        (e) 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 Commission has not issued any order preventing or suspending the use of
the Prospectus or any Preliminary Prospectus filed as a part of the Registration
Statement or any amendment thereto; no stop order suspending the effectiveness
of the Registration Statement has been issued; and to the best knowledge of the
respective signers, no proceedings for that purpose have been instituted or are
pending or contemplated under the Securities Act;  (v) the Company does not have
any material contingent obligations which are not disclosed in the Registration
Statement and the Prospectus; (vi) 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; (vii) 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; and (viii)
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 Optional
Shares are to be purchased, as the case may be.

                                       23

 
        (f) You shall have received on the Closing Date and on any later date on
which Optional Shares are 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 (viii) of paragraph (e) of this Section 10 are true and
correct.

        (g) 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 Optional Shares are 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 (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 Optional Shares are 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 shares or
the purchase of the Optional Shares as contemplated by the Prospectus.

        (h) You shall have received from Ernst & Young LLP  (accountants) 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, 1998, did
not disclose any weakness in internal controls that they considered to be
material weaknesses.

        (i) You shall have been furnished evidence in usual written or
telegraphic form from the appropriate authorities of the several jurisdictions,
or other evidence satisfactory to you, of the qualification referred to in
paragraph (f) of Section 6 hereof.

        (j) Prior to the Closing Date, the shares 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.

directors, officers, and beneficial holders of the outstanding Common Stock,
other than those persons listed on Schedule III hereto, agreements, in form
reasonably satisfactory to Volpe Brown Whelan & Company, L.L.C., stating that
without the prior written consent of Volpe Brown Whelan & Company, L.L.C., such

                                       24

 
person or entity will not, for a period of 180 days following the date the
Registration Statement became effective (i) offer, sell, contract to sell, make
any short sale (including without limitation short against the box), pledge, or
otherwise dispose of, directly or indirectly, any shares of Common Stock or any
options to acquire shares of Common Stock or securities convertible into or
exchangeable or exercisable for or any other rights to purchase or acquire
Common Stock (including without limitation, Common Stock of the Company which
may be deemed to be beneficially owned in accordance with the rules and
regulations of the Commission) other than the exercise or conversion of
outstanding options, warrants or convertible securities 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; provided, however, that
bona fide gift transactions and transfers which will not result in any change in
beneficial ownership may be permitted if the transferee enters into a lock-up
agreement in substantially the same form covering the remainder of the lock-up
period.

        (l)  You shall have received from each Selling Securityholder a 
certificate, dated as of each date on which Optional Shares are purchased, to 
the effect that such Selling Securityholder has examined the Registration 
Statement, the Prospectus, any supplements to the Prospectus and this Agreement 
and that the representations and warranties of such Selling Securityholder are 
true and correct in all material respects on and as of each date on which 
Optional Shares are purchased with the same effect as if made on such date, and 
such Selling Securityholder has complied with the agreements and satisfied the 
conditions on its part to be performed or satisfied at or prior to such date.

        (m)  You shall have received from the Company and each Selling 
Securityholder such further information, certificates and documents as you may 
reasonably request.

        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 Katten Muchin & Zavis, counsel for the Underwriters,
shall be satisfied that they comply in form and scope.

        In case any of the conditions specified in this Section 10 shall not be
fulfilled, this Agreement may be terminated by you by giving notice to the
Company and to the Selling Securityholders.  Any such termination shall be
without liability of the Company or the Selling Securityholders to the
Underwriters and without liability of the Underwriters to the Company or the
Selling Securityholders; provided, however, that (i) in the event of such
termination, the Company and the Selling Securityholders agree to indemnify and
hold harmless the Underwriters from all costs or expenses incident to the
performance of the obligations of the Company and the Selling Securityholders
under this Agreement, including all costs and expenses referred to in paragraphs
(j) and (k) 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 or the
Selling Securityholders 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.

        Section 11.  Conditions of the Obligation of the Company and the Selling
Securityholders.  The obligation of the Company and the Selling Securityholders
to deliver the shares shall be subject to the conditions that (a) the
Registration Statement shall have become effective and (b) no stop order
suspending the effectiveness thereof shall be in effect and no proceedings
therefor shall be pending or threatened by the Commission.

        In case either of the conditions specified in this Section 11 shall not
be fulfilled, this Agreement may be terminated by the Company and the Selling
Securityholders by giving notice to you. Any such termination shall be without
liability of the Company and the Selling Securityholders to the Underwriters
and without liability of the Underwriters to the Company or the Selling

                                       25

 
Securityholders; provided, however, that in the event of any such termination
the Company and the Selling Securityholders jointly and severally agree to
indemnify and hold harmless the Underwriters from all costs or expenses incident
to the performance of the obligations of the Company and the Selling
Securityholders under this Agreement, including all costs and expenses referred
to in paragraphs (j) and (k) of Section 6 hereof.

        Section 12.  Persons Entitled to Benefit of Agreement.  This Agreement
shall inure to the benefit of the Company, the Selling Securityholders and the
several Underwriters and, with respect to the provisions of Section 7 hereof,
the several parties (in addition to the Company, the Selling Securityholders 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 term "successors and
assigns" as herein used shall not include any purchaser, as such purchaser, of
any of the shares from any of the several Underwriters.

warranties and covenants in this Agreement shall remain in full force and effect
regardless of (a) any termination of this Agreement, (b) any investigation made
by or on behalf of any Underwriter or controlling person thereof, or by or on
behalf of the Company or the Selling Securityholders or their respective
directors or officers, and (c) delivery and payment for the shares under this
Agreement; provided, however, that if this Agreement is terminated prior to the
Closing Date, the provisions of paragraphs (m) and (n) of Section 6 hereof
shall be of no further force or effect.


        Section 15.  Partial Unenforceability.  The invalidity or
unenforceability of any Section, paragraph or provision of this Agreement shall
not affect the validity or enforceability of any other Section, paragraph or
provision hereof.  If any Section, paragraph or provision of this Agreement is
for any reason determined to be invalid or unenforceable, there shall be deemed
to be made such minor changes (and only such minor changes) as are necessary to
make it valid and enforceable.


        Section 16.  Applicable Law.  This Agreement shall be governed by and
construed in 

                                       26

 
accordance with the internal laws (and not the laws pertaining to conflicts of
laws) of the State of California.


        Section 17.  General.  This Agreement constitutes the entire agreement
of the parties to this Agreement and supersedes all prior written or oral and
all contemporaneous oral agreements, understandings and negotiations with
respect to the subject matter hereof.  This Agreement may be executed in several
counterparts, each one of which shall be an original, and all of which shall
constitute one and the same document.

        In this Agreement, the masculine, feminine and neuter genders and the
singular and the plural include one another.  The section headings in this
Agreement are for the convenience of the parties only and will not affect the
construction or interpretation of this Agreement.  This Agreement may be amended
or modified, and the observance of any term of this Agreement may be waived,
only by a writing signed by the Company, the Selling Securityholders and you.

        Any person executing and delivering this Agreement as Attorney-in-fact
for the Selling Securityholders represents by so doing that he has been duly
appointed as Attorney-in-fact by such Selling Securityholder pursuant to a
validly existing and binding Power of Attorney which authorizes such Attorney-
in-fact to take such action.  Any action taken under this Agreement by any of
the Attorneys-in-fact will be binding on all of the Selling Securityholders.

                                       27
