                      INTERNATIONAL UNDERWRITING AGREEMENT

                                                            September ___, 1996

Goldman Sachs International,
Deutsche Morgan Grenfell/C.J. Lawrence Inc.
Robertson, Stephens & Company
   As representatives of the several Underwriters
   named in Schedule I hereto,
c/o Goldman Sachs International,
Peterborough Court,
133 Fleet Street,
London EC4A 2BB, England.

Ladies and Gentlemen:

         Infinity Financial Technology, Inc., a Delaware corporation (the
"Company"), proposes, subject to the terms and conditions stated herein, to
issue and sell to the Underwriters named in Schedule I hereto (the
"Underwriters") an aggregate of ............. shares and, at the election of the
Underwriters, up to .............. additional shares of Common Stock $0.001 par
value, ("Stock") of the Company and the stockholders of the Company named in
Schedule II hereto (the "Selling Stockholders") propose, subject to the terms
and conditions stated herein, to sell to the Underwriters an aggregate of .....
shares and, at the election of the Underwriters, up to ............ additional
shares of Stock. The aggregate of ................ shares to be sold by the
Company and the Selling Stockholders is herein called the "Firm Shares" and the
aggregate of ................ additional shares to be sold by the Company and
the Selling Stockholders is herein called the "Optional Shares". The Firm Shares
and the Optional Shares which the Underwriters elect to purchase pursuant to
Section 2 hereof are herein collectively called, the "Shares."

         It is understood and agreed to by all parties that the Company and the
Selling Stockholders are concurrently entering into an agreement, a copy of
which is attached hereto (the "U.S. Underwriting Agreement"), providing for the
sale by the Company and the Selling Stockholders of up to a total of ....shares
of Stock (the "U.S. Shares"), including the overallotment option thereunder,
through arrangements with certain underwriters in the United States (the "U.S.
Underwriters"), for whom Goldman, Sachs & 
   2
Co., Deutsche Morgan Grenfell/C.J. Lawrence Inc. and Robertson, Stephens &
Company are acting as representatives. Anything herein or therein to the
contrary notwithstanding, the respective closings under this Agreement and the
U.S. Underwriting Agreement are hereby expressly made conditional on one
another. The Underwriters hereunder and the U.S. Underwriters are simultaneously
entering into an Agreement between U.S. and International Underwriting
Syndicates (the "Agreement between Syndicates") which provides, among other
things, for the transfer of shares of Stock between the two syndicates and for
consultation by the Lead Managers hereunder with Goldman, Sachs & Co. prior to
exercising the rights of the Underwriters under Section 7 hereof. Two forms of
prospectus are to be used in connection with the offering and sale of shares of
Stock contemplated by the foregoing, one relating to the Shares hereunder and
the other relating to the U.S. Shares. The latter form of prospectus will be
identical to the former except for certain substitute pages as included in the
registration statement and amendments thereto as mentioned below. Except as used
in Sections 2, 3, 4, 9 and 11 herein, and except as context may otherwise
require, references hereinafter to the Shares shall include all of the shares of
Stock which may be sold pursuant to either this Agreement or the U.S.
Underwriting Agreement, and references herein to any prospectus whether in
preliminary or final form, and whether as amended or supplemented, shall include
both the U.S. and the international versions thereof.

         In addition, this Agreement incorporates by reference certain
provisions from the U.S. Underwriting Agreement (including the related
definitions of terms, which are also used elsewhere herein) and, for purposes of
applying the same, references (whether in these precise words or their
equivalent) in the incorporated provisions to the "Underwriters" shall be to the
Underwriters hereunder, to the "Shares" shall be to the Shares hereunder as just
defined, to "this Agreement" (meaning therein the U.S. Underwriting Agreement)
shall be to this Agreement (except where this Agreement is already referred to
or as the context may otherwise require) and to the representatives of the
Underwriters or to Goldman, Sachs & Co. shall be to the addressees of this
Agreement and to Goldman Sachs International ("GSI"), and, in general, all such
provisions and defined terms shall be applied mutatis mutandis as if the
incorporated provisions were set forth in full herein having regard to their
context in this Agreement as opposed to the U.S. Underwriting Agreement.

         1.       The Company and each of the several Selling Stockholders
hereby make to the Underwriters the same respective representations, warranties
and agreements as are set forth in Section 1 of the U.S. Underwriting Agreement,
which Section is incorporated herein by this reference.

         2.       Subject to the terms and conditions herein set forth, the
Company and each of the Selling Stockholders agree, severally and not jointly,
to sell to each of the Underwriters, and each of the Underwriters agrees,
severally and not jointly, to purchase from the Company and each of the Selling
Stockholders, at a purchase price per share of $............, the number of Firm
Shares (to be adjusted by you so as to eliminate fractional shares) determined
by multiplying the aggregate number of Firm Shares to be sold by the Company and
each of the Selling Stockholders as set forth opposite their respective names in
Schedule II hereto by a fraction, the numerator of which is the aggregate number
of Firm Shares to be purchased by such Underwriter as set forth opposite the
name of such Underwriter in Schedule I hereto and the 

                                      -2-
   3
denominator of which is the aggregate number of Firm Shares to be purchased by
all the Underwriters from the Company and all the Selling Stockholders hereunder
and (b) in the event and to the extent that the Underwriters shall exercise the
election to purchase Optional Shares as provided below, the Company and each of
the Selling Stockholders agree, severally and not jointly, to sell to each of
the Underwriters, and each of the Underwriters agrees, severally and not
jointly, to purchase from the Company and each of the Selling Stockholders, at
the purchase price per share set forth in this Section 2, that portion of the
number of Optional Shares as to which such election shall have been exercised
(to be adjusted by you so as to eliminate fractional shares) determined by
multiplying such number of Optional Shares by a fraction the numerator of which
is the maximum number of Optional Shares which such Underwriter is entitled to
purchase as set forth opposite the name of such Underwriter in Schedule I hereto
and the denominator of which is the maximum number of Optional Shares that all
of the Underwriters are entitled to purchase hereunder.

         The Company and the Selling Stockholders, as and to the extent
indicated in Schedule II hereto, hereby grant, severally and not jointly, to the
Underwriters the right to purchase at their election up to ...................
Optional Shares, at the purchase price per share set forth in the paragraph
above, for the sole purpose of covering overallotments in the sale of the Firm
Shares. Any such election to purchase Optional Shares shall be made in
proportion to the maximum number of Optional Shares to be sold by the Company
and each Selling Stockholder as set forth in Schedule II hereto initially with
respect to the Optional Shares to be sold by the Company and then among the
Selling Stockholders in proportion to the maximum number of Optional Shares to
be sold by each Selling Stockholder as set forth in Schedule II hereto. Any such
election to purchase Optional Shares may be exercised only by written notice
from you to the Company and the Attorneys-in-Fact, given within a period of 30
calendar days after the date of this Agreement and setting forth the aggregate
number of Optional Shares to be purchased and the date on which such Optional
Shares are to be delivered, as determined by you but in no event earlier than
the First Time of Delivery (as defined in Section 4 hereof) or, unless you, the
Company and the Attorneys-in-Fact otherwise agree in writing, earlier than two
or later than ten business days after the date of such notice.

         3. Upon the authorization by GSI of the release of the Firm Shares, the
several Underwriters propose to offer the Firm Shares for sale upon the terms
and conditions set forth in the Prospectus and in the forms of Agreement among
Underwriters (International Version) and Selling Agreements, which have been
previously submitted to the Company by you. Each Underwriter hereby makes to and
with the Company and the Selling Stockholders the representations and agreements
of such Underwriter as a member of the selling group contained in Sections 3(d)
and 3(e) of the form of Selling Agreements.

         4. (a) The Shares to be purchased by each Underwriter hereunder, in
         definitive form, and in such authorized denominations and registered in
         such names as Goldman, Sachs & Co. may request upon at least
         forty-eight hours' prior notice to the Company and the Selling
         Stockholders shall be delivered by or on behalf of the Company and the
         Selling Stockholders to Goldman, Sachs & Co., through the facilities of
         The Depository Trust Company ("DTC"), for the account of such
         Underwriter, against payment by or on behalf of such Underwriter of the

                                      -3-
   4
         purchase price therefor by certified or official bank check or checks,
         payable to the order of the Company and the Custodian each, as their
         interests may appear, in federal (same day) funds. The Company will
         cause the certificates representing the Shares to be made available for
         checking and packaging at least twenty-four hours prior to the Time of
         Delivery (as defined below) with respect thereto at the office of
         Goldman, Sachs & Co., 85 Broad Street, New York, New York 10004 (the
         "Designated Office"). The time and date of such delivery and payment
         shall be, with respect to the Firm Shares, 10:00 a.m., New York City
         time, on September ___, 1996 on such other time and date as Goldman,
         Sachs & Co., the Company and the Selling Stockholders may agree upon in
         writing, and, with respect to the Optional Shares, 10:00 a.m., New York
         time, on the date specified by Goldman, Sachs & Co. in the written
         notice given by Goldman, Sachs & Co. of the Underwriters' election to
         purchase such Optional Shares, or such other time and date as Goldman,
         Sachs & Co., the Company and the Selling Stockholders may agree upon in
         writing. Such time and date for delivery of the Firm Shares is herein
         called the "First Time of Delivery", such time and date for delivery of
         the Firm Optional Shares, if not the First Time of Delivery, is herein
         called the "Second Time of Delivery", and each such time and date for
         delivery is herein called a "Time of Delivery".

                 (b) The documents to be delivered at each Time of Delivery by
         or on behalf of the parties hereto pursuant to Section 7 of the U.S.
         Underwriting Agreement, including the cross-receipt for the Shares and
         any additional documents requested by the Underwriters pursuant to
         Section 7(l) of the U.S. Underwriting Agreement will be delivered at
         the offices of Morrisson & Foerster, 755 Page Mill Road, Palo Alto,
         California 94304 (the "Closing Location"), and the Shares will be
         delivered at the Designated Office, all at each Time of Delivery. A
         meeting will be held at the Closing Location at 7:00 p.m., New York
         City time, on the New York Business Day next preceding each Time of
         Delivery, at which meeting the final drafts of the documents to be
         delivered pursuant to the preceding sentence will be available for
         review by the parties hereto. For the purposes of this Section 4, "New
         York Business Day" shall mean each Monday, Tuesday, Wednesday, Thursday
         and Friday which is not a day on which banking institutions in New York
         are generally authorized or obligated by law or executive order to
         close.

         5. The Company hereby makes with the Underwriters the same agreements
as are set forth in Section 5 of the U.S. Underwriting Agreement, which Section
is incorporated herein by this reference.

         6. The Company, each of the Selling Stockholders, and the Underwriters
hereby agree with respect to certain expenses on the same terms as are set forth
in Section 6 of the U.S. Underwriting Agreement, which Section is incorporated
herein by this reference.

         7. Subject to the provisions of the Agreement between Syndicates, the
obligations of the Underwriters hereunder shall be subject, in their discretion,
at each Time of Delivery to the condition that all representations and
warranties and other statements of the Company, and the Selling Stockholders
herein are, at and as of such Time of Delivery, true and correct, the condition
that the Company and the Selling Stockholders shall have performed all of their
respective obligations hereunder 

                                      -4-
   5
theretofore to be performed, and additional conditions identical to those set
forth in Section 7 of the U.S. Underwriting Agreement, which Section is
incorporated herein by this reference.

         8. (a) The Company and each of the Selling Stockholders listed under
Part A of Schedule ll hereto, jointly and severally, will indemnify and hold
harmless each Underwriter against any losses, claims, damages or liabilities,
joint or several, to which such Underwriter may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and will reimburse each Underwriter for
any legal or other expenses reasonably incurred by such Underwriter in
connection with investigating or defending any such action or claim as such
expenses are incurred; provided, however, that the Company and such Selling
Stockholders shall not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
any Preliminary Prospectus, the Registration Statement or the Prospectus or any
such amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by any Underwriter through Goldman, Sachs &
Co. expressly for use therein and provided further that the liability of a
Selling Stockholder pursuant to this subsection (a) shall not exceed the product
of the number of Shares sold by such Selling Stockholder and the initial public
offering price of the Shares as set forth in the Prospectus.

         (b)      Each of the Selling Stockholders listed under Part B of
Schedule ll hereto will indemnify and hold harmless each Underwriter against any
losses, claims, damages or liabilities, joint or several, to which such
Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in any Preliminary Prospectus, the Registration Statement or
the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by such Selling
Stockholder expressly for use therein; and will reimburse each Underwriter for
any legal or other expenses reasonably incurred by such Underwriter in
connection with investigating or defending any such action or claim as such
expenses are incurred; provided, however, that such Selling Stockholder shall
not be liable in any such case to the extent that any such loss, claim, damage
or liability arises out of or is based upon an untrue statement or alleged
untrue statement or omission or alleged omission made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company by any Underwriter through Goldman, Sachs & Co.
expressly for use therein and provided further that the 

                                      -5-
   6
liability of a Selling Stockholder pursuant to this Subsection (b) shall not
exceed the product of the number of Shares sold by such Selling Stockholder and
the initial public offering price of the Shares as set forth in the Prospectus.

         (c)      Each Underwriter will indemnify and hold harmless the Company
and each Selling Stockholder against any losses, claims, damages or liabilities
to which the Company or such Selling Stockholder may become subject, under the
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon an untrue statement
or alleged untrue statement of a material fact contained in any Preliminary
Prospectus, the Registration Statement or the Prospectus, or any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through Goldman, Sachs & Co.
expressly for use therein; and will reimburse the Company and each Selling
Stockholder for any legal or other expenses reasonably incurred by the Company
or such Selling Stockholder in connection with investigating or defending any
such action or claim as such expenses are incurred.

        (d)      Promptly after receipt by an indemnified party under
subsection (a), (b) or (c) above of notice of the commencement of any action,
such indemnified party shall, if a claim in respect thereof is to be made
against an indemnifying party under such subsection, notify the indemnifying
party in writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (which shall not,
except with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party shall
not be liable to such indemnified party under such subsection for any legal
expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other
than reasonable costs of investigation. No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability arising out of such action or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act, by or
on behalf of any indemnified party.

         (e)      If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a), (b) or (c) 

                                      -6-
   7
above in respect of any losses, claims, damages or liabilities (or actions in
respect thereof) referred to therein, then each indemnifying party shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (or actions in respect thereof)
in such proportion as is appropriate to reflect the relative benefits received
by the Company and the Selling Stockholders on the one hand and the Underwriters
on the other from the offering of the Shares. If, however, the allocation
provided by the immediately preceding sentence is not permitted by applicable
law or if the indemnified party failed to give the notice required under
subsection (d) above, then each indemnifying party shall contribute to such
amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and the Selling Stockholders on the one hand and the
Underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by the Company and the Selling Stockholders on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering of the Shares purchased under this
Agreement (before deducting expenses) received by the Company and the Selling
Stockholders bear to the total underwriting discounts and commissions received
by the Underwriters with respect to the Shares purchased under this Agreement,
in each case as set forth in the table on the cover page of the Prospectus. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or the Selling Stockholders on the one hand or the Underwriters on the
other and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company, each
of the Selling Stockholders and the Underwriters agree that it would not be just
and equitable if contributions pursuant to this subsection (e) were 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 account
of the equitable considerations referred to above in this subsection (e). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this subsection (e) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (e), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Shares underwritten
by it and distributed to the public were offered to the public exceeds the
amount of any damages which such Underwriter has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The Underwriters'
obligations in this subsection (e) to contribute are several in proportion to
their respective underwriting obligations and not joint.

         (f)      The obligations of the Company and the Selling Stockholders
under this Section 8 shall be in addition to any liability which the Company and
the respective Selling Stockholders may otherwise have and shall extend, upon
the same terms and conditions, to each person, if any, who controls any
Underwriter within the 

                                      -7-
   8
meaning of the Act; and the obligations of the Underwriters under this Section 8
shall be in addition to any liability which the respective Underwriters may
otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company and to each person, if any, who controls the
Company or any Selling Stockholder within the meaning of the Act.

         9. (a) If any Underwriter shall default in its obligation to purchase
the Shares which it has agreed to purchase hereunder at a Time of Delivery, you
may in your discretion arrange for you or another party or other parties to
purchase such Shares on the terms contained herein. If within thirty-six hours
after such default by any Underwriter you do not arrange for the purchase of
such Shares, then the Company and the Selling Stockholders shall be entitled to
a further period of thirty-six hours within which to procure another party or
other parties satisfactory to you to purchase such Shares on such terms. In the
event that, within the respective prescribed periods, you notify the Company and
the Selling Stockholders that you have so arranged for the purchase of such
Shares, or the Company and the Selling Stockholders notify you that they have so
arranged for the purchase of such Shares, you or the Company and the Selling
Stockholders shall have the right to postpone such Time of Delivery for a period
of not more than seven days, in order to effect whatever changes may thereby be
made necessary in the Registration Statement or the Prospectus, or in any other
documents or arrangements, and the Company agrees to file promptly any
amendments to the Registration Statement or the Prospectus which in your opinion
may thereby be made necessary. The term "Underwriter" as used in this Agreement
shall include any person substituted under this Section with like effect as if
such person had originally been a party to this Agreement with respect to such
Shares.

         (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Stockholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased does not exceed one-eleventh of
the aggregate number of all the Shares to be purchased at such Time of Deliver,
then the Company and the Selling Stockholders shall have the right to require
each non-defaulting Underwriter to purchase the number of shares which such
Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

         (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Stockholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased exceeds one-eleventh of the
aggregate number of all the Shares to be purchased at such Time of Delivery, or
if the Company and the Selling Stockholders shall not exercise the right
described in subsection (b) above to require non-defaulting Underwriters to
purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement
(or, with respect to the Second Time of Delivery, the obligations of the
Underwriters to purchase and of the Company and the Selling Stockholders to sell
the Optional Shares) shall thereupon terminate, without liability on 

                                      -8-
   9
the part of any non-defaulting Underwriter or the Company or the Selling
Stockholders, except for the expenses to be borne by the Company and the Selling
Stockholders and the Underwriters as provided in Section 6 hereof and the
indemnity and contribution agreements in Section 8 hereof; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

         10. The respective indemnities, agreements, representations, warranties
and other statements of the Company, the Selling Stockholders and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, or the Company or any of the Selling Stockholders, or any officer
or director or controlling person of the Company or any controlling person of
any Selling Stockholders, and shall survive delivery of and payment for the
Shares.

         11. If this Agreement shall be terminated pursuant to Section 9 hereof,
neither the Company nor the Selling Stockholders shall then be under any
liability to any Underwriter except as provided in Section 6 and Section 8
hereof; but, if for any other reason, any Shares are not delivered by or on
behalf of the Company and the Selling Stockholders as provided herein, the
Company and each of the Selling Stockholders pro rata (based on the number of
Shares to be sold by the Company and such Selling Stockholder hereunder) will
reimburse the Underwriters through GSI for all out-of-pocket expenses approved
in writing by GSI, including fees and disbursements of counsel, reasonably
incurred by the Underwriters in making preparations for the purchase, sale and
delivery of the Shares not so delivered, but the Company and the Selling
Stockholders shall then be under no further liability to any Underwriter [in
respect of the Shares not so delivered except as provided in Sections 6 and 8
hereof.

         12. In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by GSI on on behalf of you as the representatives of the
Underwriters; and in all dealings with any Selling Stockholder hereunder, you
