Shares, the "Underwritten Shares") as set forth in Schedule II hereto, to the
several Underwriters listed in Schedule I hereto (the "Underwriters"), for whom
you are acting as representatives (the "Representatives"). In addition, for the
sole purpose of covering over-allotments in connection with the sale of the

at the option of the Underwriters, up to an additional 1,159,500 shares (the
"Option Shares") of Common Stock. The Underwritten Shares and the Option Shares
are herein referred to as the "Shares."

                  Science Applications International Corporation, a Delaware

                  The Company has prepared and filed with the Securities and
Exchange Commission (the "Commission") in accordance with the provisions of the
Securities Act of 1933, as amended, and the rules and regulations of the
Commission thereunder (collectively, the "Securities Act"), a registration
statement on Form S-3, including a prospectus, relating to the Shares. The
registration statement as amended at the time when it became or shall become
effective, including information (if any) deemed to be part of the registration
statement at the time of effectiveness pursuant to Rule 430A under the
Securities Act, is referred to in this Agreement as the "Registration
Statement," and the prospectus in the form first used to confirm sales of Shares
is referred to in this Agreement as the "Prospectus." If the Company has filed
an abbreviated registration statement pursuant to Rule 462(b) under the
Securities Act (the "Rule 462 Registration Statement"), then any reference
herein to the term "Registration Statement" shall be deemed to include such Rule
462 Registration Statement. Any reference in this Agreement to the Registration
Statement, any preliminary prospectus or the Prospectus shall be deemed to refer
to and include the documents incorporated by reference therein pursuant to Item
12 of Form S-3 under the Securities Act, as of the effective date of the
Registration Statement or the date of such preliminary prospectus or the
Prospectus, as the case may be, and any reference to "amend," "amendment" or
"supplement" with respect to the Registration Statement, any preliminary
prospectus or the Prospectus shall be deemed to refer to and include any
documents filed after such date under the Securities Exchange Act of 1934, as
amended, and the rules and regulations of the Commission thereunder
(collectively, the "Exchange Act") that are deemed to be incorporated by
reference therein.

                  1. The Company agrees to issue and sell the Company Shares and
each of the Selling Stockholders agrees, severally and not jointly, to sell the
Selling Stockholder Shares to the several Underwriters as hereinafter provided,
and each Underwriter, upon the basis of the representations and warranties
herein contained, but subject to the conditions hereinafter stated, agrees to
purchase, severally and not jointly, from each of the Company and each of the
Selling Stockholders at a purchase price per share of $   (the "Purchase Price")
the number of Underwritten Shares (to be adjusted by you so as to eliminate
fractional shares) determined by multiplying the aggregate number of
Underwritten Shares to be sold by the Company and by each of the Selling
Stockholders as set forth opposite their respective names under the heading
"Number of Underwritten Shares" in Schedule II hereto by a fraction, the
numerator of which is the aggregate number of Underwritten Shares to be
purchased by such Underwriter as set forth opposite the name of such Underwriter
in Schedule I hereto and the denominator of which is the aggregate number of
Underwritten Shares to be purchased by all the Underwriters from the Company and
all the Selling Stockholders hereunder.

                  In addition, the Company agrees to issue and sell the Option
Shares to the several Underwriters as hereinafter provided, and the
Underwriters, upon the basis of the
   3
                                      -3-


representations and warranties herein contained, but subject to the conditions
hereinafter stated, shall have the option to purchase, severally and not
jointly, from the Company at the Purchase Price that portion of the number of
Option 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 Option Shares by a fraction, the numerator of which is the
maximum number of Option 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 Option Shares which all of the
Underwriters are entitled to purchase hereunder, for the sole purpose of
covering over-allotments (if any) in the sale of Underwritten Shares by the
several Underwriters.

                  The Underwriters may exercise the option to purchase the
Option Shares at any time (but not more than once) on or before the thirtieth
day following the date of this Agreement, by written notice from the
Representatives to the Company. Such notice shall set forth the aggregate number
of Option Shares as to which the option is being exercised and the date and time
when the Option Shares are to be delivered and paid for, which may be the same
date and time as the Closing Date (as hereinafter defined) but shall not be
earlier than the Closing Date nor later than the tenth full Business Day (as
hereinafter defined) after the date of such notice (unless such time and date
are postponed in accordance with the provisions of Section 9 hereof). Any such
notice shall be given at least two Business Days prior to the date and time of
delivery specified therein.

                  On December 21, 1999, the Company approved a 2-for-1 stock
split of the shares of Common Stock, to be effected in the form of a stock
dividend on shares of Common Stock outstanding on a date after the Closing Date
as determined by a duly appointed committee of the Board of Directors of the
Company (the "Record Date"). The stock dividend will be distributed to
stockholders a date after the Record Date as determined by a duly appointed
committee of the Board of Directors of the Company (the "Distribution Date"). In
the event the Additional Closing Date (as defined below) is after the Record
Date, the Company shall issue to each Underwriter on the Additional Closing Date
the number of Option Shares to be purchased by such Underwriter as determined
above together with a "due bill" for an equal number of shares of Common Stock
to be issued by the Company on or after the Distribution Date in exchange for
such "due bill."

                  2. The Company and the Selling Stockholders understand that
the Underwriters intend (i) to make a public offering of the Shares as soon
after (A) the Registration Statement has become effective and (B) the parties
hereto have executed and delivered this Agreement as in the judgment of the
Representatives is advisable and (ii) initially to offer the Shares upon the
terms set forth in the Prospectus.

                  3. Payment for the Shares shall be made by wire transfer in
immediately available funds to the accounts specified by the Company, in the
case of the Company Shares, and to an account specified by the Principal
Stockholder and the Attorneys-in-Fact, in the case of the Selling Stockholder
Shares, to the Representatives on    , 2000, or at such other time on the same
or such other date, not later than the fifth Business Day thereafter, as the
Representatives, the Company, the Principal Stockholder and the
Attorneys-in-Fact may agree upon in writing, or to an account specified to the
Representatives by the Company, in the case of the Option Shares, on the date
and time specified by the Representatives in the written notice of the
Underwriters' election to purchase such Option Shares. The time and date of such
payment for the Underwritten Shares is referred to herein as the "Closing Date,"
and the time and date for such payment for the Option Shares, if other than the
Closing Date, are herein referred to as the "Additional Closing Date." As used
herein, the term "Business Day" means any day other than a day on which banks
are permitted or required to be closed in New York City.

                  Payment for the Shares to be purchased on the Closing Date or
the Additional Closing Date, as the case may be, shall be made against delivery
to the Representatives for the respective accounts of the several Underwriters
of the Shares to be purchased on such date registered in such names and in such
denominations as the Representatives shall request in writing not later than two
full Business Days prior to the Closing Date or the Additional Closing Date, as
the case may be, with any transfer taxes payable in connection with the transfer
to the Underwriters of the Company Shares and the Option Shares duly paid by the
Company and any transfer taxes payable in connection with the transfer to the
Underwriters of the Selling Stockholder Shares duly paid by the Selling
Stockholders. The certificates for the Shares will be made available for
inspection and packaging by the Representatives at the office of J.P. Morgan
Securities Inc. set forth above not later than 1:00 P.M., New York City time, on
the Business Day prior to the Closing Date or the Additional Closing Date, as
the case may be.

                  4. (A) The Company represents and warrants to each Underwriter
and the Selling Stockholders that:

                  (a) each preliminary prospectus filed as part of the

         representation and warranty shall not apply to any statements in, or

         material respects with the Securities Act and do not and will not, as
         of the applicable effective date as to the Registration Statement and
         any amendment thereto and as of the date of the Prospectus and any
         amendment or supplement thereto, contain any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading, and

         case may be, conformed in all material respects to the requirements of
         the Securities Act or the Exchange Act, as applicable, and none of such

         authorized, executed and delivered and constitute valid and binding
         instruments enforceable in accordance with their terms subject, as to
         enforcement, to bankruptcy, insolvency, reorganization and other laws

         confidential information, databases, computer applications, programs
         and other software and other intellectual property (collectively, the

         Prospectus, the Company has no knowledge of infringement of or conflict
         with asserted rights of others with respect to any Intellectual
         Property, except for notices the content of which if accurate would not
         have a Material Adverse Effect;

                  (w) there are no existing or, to the knowledge of the Company,
         threatened labor disputes with the employees of the Company or any of

         contaminants ("Environmental Laws"), (ii) have received all permits,
         licenses or other approvals required of it under applicable
         Environmental Laws to conduct its businesses and (iii) are in
         compliance with all terms and conditions of any such permit, license or

         failure to receive required permits, licenses or other approvals or
         failure to comply with the terms and conditions of such permits,
         licenses or approvals would not, singly or in the aggregate, have a

         3(3) of the Employee Retirement Income Security Act of 1974, as amended
         ("ERISA"), that is maintained, administered or contributed to by the
         Company or any of its affiliates for employees or former employees of
         the Company and its affiliates has been maintained in material
         compliance with its terms and the requirements of any applicable
         statutes, orders, rules and regulations, including but not limited to
         ERISA and the Internal Revenue Code of 1986, as amended ("Code"). No
         prohibited transaction, within the meaning of Section 406 of ERISA or
         Section 4975 of the Code, has occurred with respect to any such plan
         excluding transactions effected pursuant to a statutory or

         "accumulated
   11
                                      -11-


         funding deficiency," as defined in Section 412 of the Code, has been
         incurred, whether or not waived, and the fair market value of the
         assets of each such plan (excluding for these purposes accrued but
         unpaid contributions) exceed the present value of all benefits accrued
         under such plan determined using reasonable actuarial assumptions.

                  (B) The Principal Stockholder hereby represents and warrants
to each of the Underwriters, the Company and the Management Stockholders that:

                  (a) the Principal Stockholder has been duly incorporated and
         is validly existing as a corporation in good standing under the laws of
         the State of Delaware;

                  (b) the Principal Stockholder has good and marketable title to
         all the Shares to be sold by the Principal Stockholder hereunder, in
         each case free and clear of all liens, encumbrances, equities, security
         interests and claims whatsoever, with full right and authority to
         deliver the same hereunder, and upon the delivery of and payment for
         such Shares hereunder, the several Underwriters will receive good and
         marketable title thereto, free and clear of all liens, encumbrances,
         equities, security interests or claims whatsoever;

                  (c) the Principal Stockholder has not taken nor will it take,
         directly or indirectly, any action which is designed to, or that might
         reasonably be expected to, cause or result in stabilization or
         manipulation of the price of the Common Stock;

                  (d) the Principal Stockholder has no actual knowledge that the
         representations and warranties of the Company contained in Section 4(A)
         of this Agreement are not true and correct, is familiar with the
         Registration Statement and has no knowledge of any material fact,
         condition or information not disclosed in the Registration Statement
         which has had or may have a Material Adverse Effect; the sale of the
         Shares by the Principal Stockholder pursuant to this Agreement is not
         prompted by any information concerning the Company which is not set
         forth in the Registration Statement; and the information pertaining to
         such Principal Stockholder under the caption "Selling Stockholders" in
         the Prospectus is complete and accurate in all material respects;

                  (e) the Registration Statement and the Prospectus (as amended
         or supplemented) comply, or will comply, as the case may be, in all
         material respects with the Securities Act and do not and will not, as
         of the applicable effective date of the Registration Statement and any
         amendment thereto and as of the date of the Prospectus and any
         amendment or supplement thereto, contain any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary
   12
                                      -12-


         to make the statements therein not misleading, and the Prospectus, as
         amended or supplemented, if applicable, at the Closing Date or
         Additional Closing Date, as the case may be, will not contain any
         untrue statement of a material fact or omit to state a material fact
         necessary to make the statements therein, in light of the circumstances
         under which they were made, not misleading, except that the foregoing
         representations and warranties shall not apply to statements or
         omissions in the Registration Statement or the Prospectus made in
         reliance upon and in conformity with information furnished to the
         Company in writing by or on behalf of the Underwriters through the
         Representatives expressly for use therein;

                  (f) this Agreement has been duly authorized, executed and
         delivered by the Principal Stockholder; and

                  (g) the sale of the Shares by the Principal Stockholder
         hereunder, the compliance by the Principal Stockholder with all of the
         provisions of this Agreement and the consummation of the transactions
         contemplated herein will not conflict with or result in a breach or
         violation of any of the terms or provisions of, or constitute a default
         under (in each case material to the Principal Stockholder and its
         subsidiaries, considered as a whole), any indenture, mortgage, deed of
         trust, loan agreement, lease or other agreement or instrument to which
         the Principal Stockholder is a party or by which the Principal
         Stockholder is bound or to which any of the property or assets of the
         Principal Stockholder is subject, nor will such action result in any
         violation of the provisions of the certificate of incorporation or
         by-laws of the Principal Stockholder, nor will such action result in
         any violation (in each case material to the Principal Stockholder and
         its subsidiaries, considered as a whole) of any applicable statute or
         any applicable order, rule or regulation of any court or governmental
         agency or body having jurisdiction over the Principal Stockholder or
         any of its properties; no consent, approval, authorization, order,
         registration or qualification of or with any such court or governmental
         agency or body is required for the sale of the Shares or the
         consummation by the Principal Stockholder of the transactions
         contemplated by this Agreement, except such consents, approvals,
         authorizations, orders, licenses, registrations or qualifications as
         have been obtained or made under the Securities Act or the Exchange Act
         and as may be required under state securities or blue sky laws in
         connection with the purchase and distribution of the Shares by the
         Underwriters; the Principal Stockholder has full right, power and
         authority to enter into this Agreement and to sell, assign, transfer
         and deliver the Shares to be sold by it; each agreement between the
         Company and the Principal Stockholder referred to in the Prospectus has
         been duly executed and delivered by the Principal Stockholder and
         constitutes a valid and binding obligation of the Principal Stockholder
         enforceable against the Principal Stockholder in accordance with its
         terms.

         necessary for the execution and delivery by such Management Stockholder
         of this Agreement and the Power of Attorney (the "Power of Attorney")
         and the Custody Agreement (the "Custody Agreement") hereinafter
         referred to, and for the sale and delivery of the Shares to be sold by
         such Management Stockholder hereunder, have been obtained; and such
         Management Stockholder has full right, power and authority to enter
         into this Agreement, the Power of Attorney and the Custody Agreement
         and to sell, assign, transfer and deliver the Shares to be sold by such

         delivered by such Management Stockholder;

                  (b) the sale of the Shares to be sold by such Management
         Stockholder hereunder and the compliance by such Management Stockholder

         and therein contemplated will not conflict with or result in a breach
         or violation of any of the terms or provisions of, or constitute a
         default under, any statute or any indenture, mortgage, deed of trust,
         loan agreement or other agreement or instrument to which such
         Management Stockholder is a party or by which such Management
         Stockholder is bound or to which any of the property or assets of such
         Management Stockholder is subject, nor will such action result in any
         violation of any statute or any order, rule or regulation of any court
         or governmental agency or body having jurisdiction over such Management
         Stockholder or the property of such Management Stockholder;

                  (c) such Management Stockholder has good and valid title to
         the Shares to be sold at the Closing Date by such Management
         Stockholder hereunder (other than the Shares to be issued upon exercise
         of Options), free and clear of all liens, encumbrances, equities or
         adverse claims; such Management Stockholder will have, immediately
         prior to the Closing Date, assuming due issuance of any Shares to be
         issued upon exercise of Options, good and valid title to the Shares to
         be sold at the Closing Date by such Management Stockholder, free and
         clear of all liens, encumbrances, equities or adverse claims; and, upon
         delivery of the certificates representing such Shares and payment
         therefor pursuant hereto, good and valid title to such Shares, free and
         clear of all liens, encumbrances, equities, security interests or
         claims, will pass to the several Underwriters;

                  (d) such Management Stockholder has not taken nor will such
         Management Stockholder take, directly or indirectly, any action which
         is designed to, or that
   14
                                      -14-


         might reasonably be expected to cause or result in stabilization or
         manipulation of the price of the Common Stock;

                  (e) the information pertaining to such Management Stockholder
         under the caption "Selling Stockholders" in the Prospectus is complete
         and accurate in all material respects;

                  (f) when the Registration Statement becomes effective and at
         all times subsequent thereto through the latest of the Closing Date,
         the Additional Closing Date or the termination of the offering of the
         Shares, such parts of the Registration Statement and Prospectus, and
         any supplements or amendments thereto, as they relate to such
         Management Stockholder will not contain an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading; and

                  (g) the lock-up letter previously delivered to the
         Underwriters by such Management Stockholder is in full force and effect
         on the date of this Agreement.

                  (D) Robert J. Korzeniewski (the "Senior Management
Stockholder") represents and warrants to each of the Underwriters that such
Senior Management Stockholder has no reason to believe that the representations
and warranties of the Company contained in Section 4(A) of this Agreement are
not true and correct in all material respects.

                  Each of the Management Stockholders severally represents and
warrants to each of the Underwriters that certificates in negotiable form
representing all of the Shares to be sold by such Management Stockholders
hereunder, other than any such Shares to be issued upon the exercise of Options,
have been, and each of the Management Stockholders who is selling Shares upon
the exercise of Options to each of the Underwriters represents and warrants that
duly completed and executed irrevocable Option exercise notices, in the forms
specified by the relevant Option Agreement, with respect to all of the Shares to
be sold by such Management Stockholder to each of the Underwriters hereunder
have been, placed in custody under a Custody Agreement relating to such Shares,
in the form heretofore furnished to you, duly executed and delivered by such
Management Stockholder to the Company, as custodian (the "Custodian"), and that
such Management Stockholder has duly executed and delivered Powers of Attorney,
in the form heretofore furnished to you, appointing the person or persons
indicated in such Power of Attorney, and each of them, as such Management
Stockholder's Attorneys-in-Fact (the "Attorneys-in-Fact" or any one of them the
"Attorney-in Fact") with authority to execute and deliver this Agreement on
behalf of such Management Stockholder, to determine the purchase price to be
paid by the Underwriters to the Management Stockholders as provided herein, to
authorize the delivery of the Shares to be sold by such Management Stockholder
hereunder, to effect (if applicable) the
   15
                                      -15-


exercise of the Options to be exercised with respect to the Shares to be sold by
such Management Stockholder hereunder and otherwise to act on behalf of such
Management Stockholder in connection with the transactions contemplated by this
Agreement and the Custody Agreement.

                  Each of the Management Stockholders specifically agrees that
the Shares represented by the certificates or the irrevocable Option exercise
notice, in either case held in custody for such Management Stockholder under the
Custody Agreement, are subject to the interests of the Underwriters hereunder,
and that the arrangements made by such Management Stockholder for such custody,
and the appointment by such Management Stockholder of the Attorneys-in-Fact by
the Power of Attorney, are to that extent irrevocable. Each of the Management
Stockholders specifically agrees that the obligations of such Management
Stockholder hereunder shall not be terminated by operation of law, whether by
the death or incapacity of any individual Management Stockholder, or, in the
case of an estate or trust, by the death or incapacity of any executor or
trustee or the termination of such estate or trust, or in the case of a
partnership or corporation, by the dissolution of such partnership or
corporation, or by the occurrence of any other event. If any individual
Management Stockholder or any such executor or trustee should die or become
incapacitated, or if any such estate or trust should be terminated, or if any
such partnership or corporation should be dissolved, or if any other such event
should occur, before the delivery of the Shares by it hereunder, certificates
representing such Shares shall be delivered by or on behalf of such Management
Stockholder in accordance with their terms and conditions of this Agreement and
the Custody Agreement, and actions taken by the Attorneys-in-Fact pursuant to
the Powers of Attorney shall be as valid as if such death, incapacity,
termination, dissolution or other event had not occurred, regardless of whether
or not the Custodian, the Attorneys-in-Fact, or any of them, shall have received
notice of such death, incapacity, termination, dissolution or other event.

                  5. (A) The Company covenants and agrees with each of the
several Underwriters as follows:

                  (a) to use its best efforts to cause the Registration
         Statement to become effective at the earliest possible time and, if
         required, to file the final Prospectus with the Commission within the
         time periods specified by Rule 424(b) and Rule 430A under the
         Securities Act and to file promptly all reports and any definitive
         proxy or information statements required to be filed by the Company
         with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of
         the Exchange Act subsequent to the date of the Prospectus and for so
         long as the delivery of a prospectus is required in connection with the
         offering or sale of the Shares; and to furnish copies of the Prospectus
         to the Underwriters in New York City prior to 10:00 a.m., New York City

         on the Business Day next succeeding the date of this Agreement in such
         quantities as the Representatives may reasonably request;

         Representatives seven signed copies of the Registration Statement (as
         originally filed) and each amendment thereto, in each case including
         exhibits and documents incorporated by reference therein, and to each
         other Underwriter a conformed copy of the Registration Statement (as
         originally filed) and each amendment thereto, in each case without
         exhibits but including the documents incorporated by reference therein
         and, during the period in which a prospectus is required by law to be
         delivered by an Underwriter or a dealer, to each of the Underwriters as
         many copies of the Prospectus (including all amendments and supplements
         thereto) and documents incorporated by reference therein as the
         Representatives may reasonably request for the purposes contemplated by
         the Securities Act;

                  (c) before filing any amendment or supplement to the
         Registration Statement or the Prospectus, whether before or after the
         time the Registration Statement becomes effective, to furnish to the
         Representatives a copy of the proposed amendment or supplement for
         review and not to file any such proposed amendment or supplement to
         which the Representatives reasonably object;

                  (d) to advise the Representatives promptly, and to confirm
         such advice in writing (i) when the Registration Statement has become
         effective, (ii) when any amendment to the Registration Statement has
         been filed or becomes effective, (iii) when any supplement to the
         Prospectus or any amended Prospectus has been filed and to furnish the
         Representatives with copies thereof, (iv) of any request by the
         Commission for any amendment to the Registration Statement or any
         amendment or supplement to the Prospectus or for any additional
         information, (v) of the issuance by the Commission of any stop order
         suspending the effectiveness of the Registration Statement or of any
         order preventing or suspending the use of any preliminary prospectus or
         the Prospectus or the initiation or threatening of any proceeding for
         that purpose, (vi) of the occurrence of any event, within the period
         referenced in paragraph (e) below, as a result of which the Prospectus
         as then amended or supplemented would include an 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 when the
         Prospectus is delivered to a purchaser, not misleading, and (vii) of
         the receipt by the Company of any notification with respect to any
         suspension of the qualification of the Shares for offer and sale in any
         jurisdiction or the initiation or threatening of any proceeding for
         such purpose; and to use its best efforts to prevent the issuance of
         any such stop order, or of any order preventing or suspending the use
         of any preliminary prospectus or the Prospectus, or of any order
   17
                                      -17-


         suspending any such qualification of the shares, or notification of any
         such order thereof and, if issued, to obtain as soon as possible the
         withdrawal thereof;

                  (e) if, during such period of time after the first date of the
         public offering of the Shares as in the opinion of counsel for the
         Underwriters a prospectus relating to the Shares is required by law to
         be delivered in connection with sales by the Underwriters or any
         dealer, any event shall occur as a result of which it is necessary to
         amend or supplement the Prospectus in order to make the statements
         therein, in light of the circumstances when the Prospectus is delivered
         to a purchaser, not misleading, or if it is necessary to amend or
         supplement the Prospectus to comply with law, forthwith to prepare and
         furnish, at the expense of the Company, to the Underwriters and to the
         dealers (whose names and addresses the Representatives will furnish to
         the Company) to which Shares may have been sold by the Representatives
         on behalf of the Underwriters and to any other dealers upon request,
         such amendments or supplements to the Prospectus as may be necessary so
         that the statements in the Prospectus as so amended or supplemented
         will not, in the light of the circumstances when the Prospectus is
         delivered to a purchaser, be misleading or so that the Prospectus will
         comply with law;

                  (f) to endeavor to qualify the Shares for offer and sale under
         the securities or blue sky laws of such jurisdictions as the
         Representatives shall reasonably request and to continue such

                  been duly authorized, executed and delivered by each
                  Management Stockholder and constitute valid and binding
                  agreements of each Management Stockholder in accordance with
                  their terms; the Attorneys-in-Fact have been duly authorized
                  by the Management Stockholders to execute and deliver on their
                  behalf this Agreement and any other document necessary or
                  desirable in connection with the transactions contemplated
                  hereby and to deliver the Shares to be sold by the Management
                  Stockholders and receive payment therefor pursuant hereto;

                           (xii) each of the intercompany agreements referred to
                  in the Prospectus has been duly authorized, executed and
                  delivered by the Company and the Principal Stockholder;

                           (xiii) the execution, delivery and performance by the
                  Company and the Selling Stockholders of the Underwriting
                  Agreement, the sale by the Selling Stockholders of the
                  Underwritten Shares and the issuance and sale by the Company
                  of the Company Shares and the Option Shares, each as
                  contemplated by the Underwriting Agreement, have been duly
                  authorized on the part of the Company and each of the Selling
                  Stockholders and will not conflict with, or result in a breach
                  of, the Certificate of Incorporation or Bylaws of the Company
                  or the Principal Stockholder or any agreement (including,
                  without limitation, the Cooperative Agreement) or instrument
                  known to such counsel to which the Company or any Selling
                  Stockholder is a party or any applicable law or regulation, or
                  so far as is known to such counsel, any order, writ,
                  injunction or decree, or any jurisdiction, court or
                  governmental instrumentality;

                           (xiv) all holders of securities of the Company having
                  rights to the registration of shares of Common Stock, or other
                  securities, because of the filing of the Registration
                  Statement by the Company have waived such rights or such
                  rights have expired by reason of lapse of time following
                  notification of the Company's intent to file the Registration
                  Statement;

                           (xv) no consent, approval, authorization or order of
                  any court or governmental agency or body is required for the
                  consummation of the transac-
   25
                                      -25-


                  tions contemplated in the Underwriting Agreement, except such
                  as have been obtained under the Securities Act and such as may
                  be required under state securities or blue sky laws in
                  connection with the purchase and distribution of the Shares by
                  the Underwriters;

                           (xvi) each Selling Stockholder is the sole registered
                  owner of the Shares to be sold by such Selling Stockholder
                  under the Underwriting Agreement; the Principal Stockholder
                  has full corporate power, right and authority to sell the
                  Shares sold by it; and

                           (xvii) good and marketable title to the Shares sold
                  by each Selling Stockholder under the Underwriting Agreement,
                  free and clear of all liens, encumbrances, equities, security
                  interests and claims, has been transferred to the
                  Underwriters, who have severally purchased such Shares under
                  the Underwriting Agreement, assuming for the purpose of this
                  opinion that the Underwriters purchased the same in good faith
                  without notice of any adverse claims.

                  In rendering such opinions, such counsel may rely (A) as to
         matters involving the application of laws other than the laws of the
         United States and the States of New York, Delaware and California, to
         the extent such counsel deems proper and to the extent specified in
         such opinion, if at all, upon an opinion or opinions (in form and
         substance reasonably satisfactory to Underwriters' counsel) of other
         counsel reasonably acceptable to the Underwriters' counsel, familiar
         with the applicable laws; (B) as to matters of fact, to the extent such
         counsel deems proper, on certificates of responsible officers of the
         Company and certificates or other written statements of officials of
         jurisdictions having custody of documents respecting the corporate
         existence or good standing of the Company. The opinion of such counsel
         for the Company shall state that the opinion of any such other counsel
         upon which they relied is in form satisfactory to such counsel and, in
         such counsel's opinion, the Underwriters and they are justified in
         relying thereon. With respect to the matters to be covered in
         subparagraph (vi) above counsel may state their opinion and belief is
         based upon their participation in the preparation of the Registration
         Statement and the Prospectus and any amendment or supplement thereto
         (other than the documents incorporated by reference therein) and review
         and discussion of the contents thereof (including the documents
         incorporated by reference therein) but is without independent check or
         verification except as specified.

                  The opinion of Pillsbury, Madison & Sutro LLP described above
         shall be rendered to the Underwriters at the request of the Company and
         shall so state therein.

                  (g) on the date hereof and the effective date of the most
         recently filed post-effective amendment filed on or subsequent to the
         date hereof to the Registration Statement and also on the Closing Date
         or Additional Closing Date, as the case may be, PricewaterhouseCoopers
         shall have furnished to you letters, dated the respective dates of
         delivery thereof, in form and substance satisfactory to you, containing
         statements and information of the type customarily included in
         accountants' "comfort letters" to underwriters with respect to the
         financial statements and certain financial information contained or
         incorporated by reference in the Registration Statement and the
         Prospectus;

                  (h) the Representatives shall have received on and as of the
         Closing Date or Additional Closing Date, as the case may be, an opinion
         of Cahill Gordon & Reindel, counsel to the Underwriters, with respect
         to the due authorization and valid issuance of the Shares, the
         Registration Statement, the Prospectus and other related matters as the
         Representatives may reasonably request, and such counsel shall have
         received such papers and information as they may reasonably request to
         enable them to pass upon such matters;

                  (i) the Shares to be delivered on the Closing Date or
         Additional Closing Date, as the case may be, shall have been approved
         for listing on the Nasdaq National Market, subject to official notice
         of issuance;

                  (j) on or prior to the Closing Date or Additional Closing
         Date, as the case may be, the Company and the Selling Stockholders
         shall have furnished to the Representatives such further certificates
         and documents as the Representatives shall reasonably request; and

                  (k) the lock-up agreements of each of the Company's executive
         officers and directors, delivered to you on or before the date hereof,
         shall be in full force and effect on the Closing Date or Additional
         Closing Date, as the case may be.

                  7. Each of the Company, the Principal Stockholder and the
Senior Management Stockholder agrees, jointly and severally, to indemnify and
hold harmless each Underwriter and each person, if any, who controls any
Underwriter within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act, from and against any and all losses, claims,
damages and liabilities (including, without limitation, the legal fees and other
expenses incurred in connection with any suit, action or proceeding or any claim
asserted) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement or the Prospectus (as
amended or supplemented if the Company shall have furnished any amendments or
supplements thereto) or any preliminary prospectus, or caused by any omission or
alleged omission to state therein a material

   27
                                      -27-



fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as such losses, claims, damages or liabilities
are caused by any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with information relating to
any Underwriter furnished to the Company in writing by such Underwriter through
the Representatives expressly for use therein; provided, however, that the
obligations of each of the Principal Stockholder and the Senior Management
Stockholder under the foregoing indemnity shall not exceed the net proceeds
received by such Selling Stockholder from the sale of Shares sold by such
Selling Stockholder hereunder (which net proceeds shall not include the
Underwriters' discount and, in the event the Senior Management Stockholder sells
Shares upon the exercise of Options, shall not include the amount remitted to
the Company to effect the exercise thereof); and provided, further, that the
foregoing indemnity shall not inure to the benefit of any Underwriter from whom
the person asserting such losses, claims, damages, liabilities and judgments
purchased Shares, or any person controlling such Underwriter, if a copy of the
Prospectus (including any amendment or supplement thereto) was not sent or given
by or on behalf of such Underwriter to such person at or prior to the written
confirmation of the sale of the Shares to such person, and if the Prospectus
(including any amendment or supplement thereto) would have cured the defect
giving rise to such losses, claims, damages, liabilities or judgments, unless
such failure to deliver a copy of the Prospectus was a result of the failure of
the Company to provide as many copies of such Prospectus as such Underwriter may
reasonably request in a timely manner.

                  Each of Craig I. Fields and Jonathan W. Emery (together, the
"Other Management Stockholders") agrees, severally and not jointly, to indemnify
and hold harmless each Underwriter and each person, if any, who controls any
Underwriter within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act to the same extent as the foregoing indemnity
from the Company, the Principal Stockholders and the Senior Management
Stockholder to each Underwriter, but only with reference to information
furnished to the Company in writing by or on behalf of such Other Management
Stockholder expressly for use in the Registration Statement, the Prospectus, any
amendment and supplement thereto, or any preliminary prospectus; provided,
however, that the obligations of each of the Other Management Stockholders under
the foregoing indemnity shall not exceed the net proceeds received by such Other
Management Stockholder from the sale of Shares sold by such Other Management
Stockholder hereunder (which net proceeds shall not include the Underwriters'
discount and, in the case of an Other Management Stockholder who sells Shares
upon the exercise of Options, shall not include the amount remitted to the
Company to effect the exercise thereof).

                  Each Underwriter agrees, severally and not jointly, to
indemnify and hold harmless the Company, its directors, its officers who sign
the Registration Statement and each person who controls the Company within the
meaning of Section 15 of the Securities
   28
                                      -28-


Act and Section 20 of the Exchange Act and each of the Selling Stockholders to
the same extent as the foregoing indemnities from the Company and the Selling
Stockholders to each Underwriter, but only with reference to information
furnished to the Company in writing by or on behalf of the Underwriters through
the Representatives expressly for use in the Registration Statement, the
Prospectus, any amendment or supplement thereto, or any preliminary prospectus.

                  If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any person in respect of which indemnity may be sought pursuant to the preceding
paragraphs of this Section 7, such person (the "Indemnified Person") shall
promptly notify the person or persons against whom such indemnity may be sought
(each an "Indemnifying Person") in writing, and such Indemnifying Persons, upon
request of the Indemnified Person, shall retain counsel reasonably satisfactory
to the Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Persons may designate in such proceeding and shall pay the fees and
expenses of such counsel related to such proceeding. In any such proceeding, any
Indemnified Person shall have the right to retain its own counsel, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Person
and not the Indemnifying Persons unless (i) the Indemnifying Persons and the
Indemnified Person shall have mutually agreed to the contrary, (ii) the
Indemnifying Persons has failed within a reasonable time to retain counsel
reasonably satisfactory to the Indemnified Person or (iii) the named parties in
any such proceeding (including any impleaded parties) include both an
Indemnifying Person and the Indemnified Person and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that no Indemnifying Person
shall, in connection with any proceeding or related proceeding in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all Indemnified Persons, and that all
such fees and expenses shall be reimbursed as they are incurred. Any such
separate firm for the Underwriters and such control persons of Underwriters
shall be designated in writing by J.P. Morgan Securities Inc. and any such
separate firm for the Company, its directors, its officers who sign the
Registration Statement and such control persons of the Company shall be
designated in writing by the Company and any such separate firm for the Selling
Stockholders shall be designated in writing by the Attorney-in-Fact. No
Indemnifying Person shall be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, each Indemnifying Person agrees to
indemnify any Indemnified Person from and against any loss or liability by
reason of such settlement or judgment. Notwithstanding the foregoing sentence,
if at any time an Indemnified Person shall have requested an Indemnifying Person
to reimburse the Indemnified Person for fees and expenses of counsel as
contemplated by the second and third sentences of this paragraph, such
Indemnifying Person agrees that it shall be liable for any set-
   29
                                      -29-


tlement of any proceeding effected without its written consent if (i) such
settlement is entered into more than 30 days after receipt by such Indemnifying
Person of the aforesaid request and (ii) such Indemnifying Person shall not have
reimbursed the Indemnified Person in accordance with such request prior to the
date of such settlement. No Indemnifying Person shall, without the prior written
consent of the Indemnified Person, effect any settlement of any pending or
threatened proceeding in respect of which any Indemnified Person is or could
have been a party and indemnity could have been sought hereunder by such
Indemnified Person, unless such settlement includes an unconditional release of
such Indemnified Person from all liability on claims that are the subject matter
of such proceeding.

                  If the indemnification provided for in the first four
paragraphs of this Section 7 is unavailable to an Indemnified Person or
insufficient in respect of any losses, claims, damages or liabilities referred
to therein, then each Indemnifying Person under such paragraph, in lieu of
indemnifying such Indemnified Person thereunder, shall contribute to the amount
paid or payable by such Indemnified Person as a result of such losses, claims,
damages or liabilities (i) 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 hand 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
the Company and the Selling Stockholders on the one hand and the Underwriters on
the other hand in connection with the statements or omissions that resulted in
such losses, claims, damages or liabilities, 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 hand
shall be deemed to be in the same respective proportions as the net proceeds
from the offering (before deducting expenses) received by the Company and the
Selling Stockholders and the total underwriting discounts and the commissions
received by the Underwriters, in each case as set forth in the table on the
cover of the Prospectus, bear to the aggregate public offering price of the
Shares. The relative fault of the Company and the Selling Stockholders on the
one hand and the Underwriters on the other hand 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 and the Selling Stockholders and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

                  The Company, the Selling Stockholders and the Underwriters
agree that it would not be just and equitable if contribution pursuant to this
Section 7 were determined by pro rata allocation (even if the Selling
Stockholders or the Underwriters were treated as one entity for such purposes)
or by any other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph.
   30
                                      -30-


The amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses incurred by such Indemnified Person in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7, (i) in no event shall an
Underwriter 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 that
such Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission and (ii) in no event
shall a Selling Stockholder be required to contribute any amount in excess of
the amount by which the net proceeds received by it through the sale of its
shares to the Underwriters exceeds the amount of any damages that such Selling
Stockholder has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission (which net proceeds, in
the case of a Management Stockholder who sell Shares upon the exercise of
Options, shall not include the amount remitted to the Company to effect the
exercise thereof). No person guilty of fraudulent misrepresentation (within the
meaning of Section ll(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute pursuant to this
Section 7 are several in proportion to the respective number of Shares set forth
opposite their names in Schedule I hereto, and not joint.

                  The remedies provided for in this Section 7 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any indemnified party at law or in equity.

                  The indemnity and contribution agreements contained in this
Section 7 and the representations and warranties of the Company and the Selling
Stockholders set forth in this Agreement shall remain operative and in full
force and effect regardless of (i) any termination of this Agreement, (ii) any
investigation made by or on behalf of any Underwriter or any person controlling
any Underwriter or by or on behalf of the Company, its officers or directors or
any other person controlling the Company or the Selling Stockholders and (iii)
acceptance of and payment for any of the Shares.

                  8. Notwithstanding anything herein contained, this Agreement
(or the obligations of the several Underwriters with respect to the Option
Shares) may be terminated in the absolute discretion of the Representatives, by
notice given to the Company and the Selling Stockholders, if after the execution
and delivery of this Agreement and prior to the Closing Date (or, in the case of
the Option Shares, to the Company prior to the Additional Closing Date) (i)
trading generally shall have been suspended or materially limited on or by, as
the case may be, any of the New York Stock Exchange or the American Stock
Exchange, the National Association of Securities Dealers, Inc., the Chicago
Board Options Exchange,
   31
                                      -31-


the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of
any securities of or guaranteed by the Company shall have been suspended on any
exchange or in any over-the-counter market, (iii) a general moratorium on
commercial banking activities in New York shall have been declared by either
Federal or New York State authorities, or (iv) there shall have occurred any
outbreak or escalation of hostilities or any change in financial markets or any
calamity or crisis that, in the judgment of the Representatives, is material and
adverse and which, in the judgment of the Representatives, makes it
impracticable to market the Shares being delivered at the Closing Date or the
Additional Closing Date, as the case may be, on the terms and in the manner
contemplated in the Prospectus.

                  9. This Agreement shall become effective upon the later of (x)
execution and delivery hereof by the parties hereto and (y) release of
notification of the effectiveness of the Registration Statement (or, if
applicable, any post-effective amendment) by the Commission.

                  If on the Closing Date or the Additional Closing Date, as the
case may be, any one or more of the Underwriters shall fail or refuse to
purchase Shares which it or they have agreed to purchase hereunder on such date,
and the aggregate number of Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase is not more than one-tenth
of the aggregate number of Shares to be purchased on such date, the other
Underwriters shall be obligated severally in the proportions that the number of
Shares set forth opposite their respective names in Schedule I bears to the
aggregate number of Underwritten Shares set forth opposite the names of all such
non-defaulting Underwriters, or in such other proportions as the Representatives
may specify, to purchase the Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date; provided
that in no event shall the number of Shares that any Underwriter has agreed to
purchase pursuant to Section 1 be increased pursuant to this Section 9 by an
amount in excess of one-ninth of such number of Shares without the written
consent of such Underwriter. If on the Closing Date or the Additional Closing
Date, as the case may be, any Underwriter or Underwriters shall fail or refuse
to purchase Shares which it or they have agreed to purchase hereunder on such
date, and the aggregate number of Shares with respect to which such default
occurs is more than one-tenth of the aggregate number of Shares to be purchased
on such date, and arrangements satisfactory to the Representatives, the Company
and the Selling Stockholders for the purchase of such Shares are not made within
36 hours after such default, this Agreement (or the obligations of the several
Underwriters to purchase the Option Shares, as the case may be, failing such
arrangements satisfactory to the Representatives and the Company) shall
terminate without liability on the part of any non-defaulting Underwriter, the
Company or the Selling Stockholders. In any such case either you, the Company or
the Selling Stockholders shall have the right to postpone the Closing Date (or,
in the case of the Option Shares, either you, the Company or the Company shall
have the right to postpone the Additional Closing Date), but in no event for
   32
                                      -32-



longer than seven days, in order that the required changes, if any, in the
Registration Statement and in the Prospectus or in any other documents or
arrangements may be effected. Any action taken under this paragraph shall not
relieve any defaulting Underwriter from liability in respect of any default of
such Underwriter under this Agreement.

                  10. If this Agreement shall be terminated by the Underwriters,
or any of them, because of any failure or refusal on the part of the Company or
the Selling Stockholders to comply with the terms or to fulfill any of the
conditions of this Agreement, or if for any reason any of the Company or the
Selling Stockholders shall be unable to perform its obligations under this
Agreement or any condition of the Underwriters' obligations cannot be fulfilled,
the Company and the Selling Stockholders agree to reimburse the Underwriters or
such Underwriters as have so terminated this Agreement with respect to
themselves, severally, for all out-of-pocket expenses (including the fees and
expenses of its counsel) reasonably incurred by the Underwriter in connection
with this Agreement or the offering contemplated hereunder.

                  11. This Agreement shall inure to the benefit of and be
binding upon the Company, the Selling Stockholders and the Underwriters any
controlling persons referred to herein and their respective successors and
assigns. Nothing expressed or mentioned in this Agreement is intended or shall
be construed to give any other person, firm or corporation any legal or
equitable right, remedy or claim under or in respect of this Agreement or any
provision herein contained. No purchaser of Shares from any Underwriter shall be
deemed to be a successor by reason merely of such purchase.

                  12. Any action by the Underwriters hereunder may be taken by
the Representatives jointly or by J.P. Morgan Securities Inc. alone on behalf of
the Underwriters, and any such action taken by the Representatives jointly or by
J.P. Morgan Securities Inc. alone shall be binding upon the Underwriters. All
notices and other communications hereunder shall be in writing and shall be
deemed to have been duly given if mailed or transmitted by any standard form of
telecommunication. Notices to the Underwriters shall be given to the
Representatives, c/o J.P. Morgan Securities Inc., 60 Wall Street, New York, New
