SoundView Technology Group
 As Representatives of the Several Underwriters,
  c/o Credit Suisse First Boston Corporation,
       Eleven Madison Avenue,
       New York, N.Y. 10010-3629

Dear Sirs:

     1.  Introductory. InterTrust Technologies Corporation, a Delaware
corporation ("Company"), proposes to issue and sell shares ("Firm Securities")
of its Common Stock, $0.001 par value ("Securities"), and also proposes to issue
and sell to the Underwriters, at the option of the Underwriters, an aggregate of
not more than additional shares ("Optional Securities") of its Securities as set
forth below. The Firm Securities and the Optional Securities are herein
collectively called the "Offered Securities". As part of the offering
contemplated by this Agreement, Salomon Smith Barney (the "Designated
Underwriter") has agreed to reserve out of the Firm Securities set forth
opposite its name on Schedule A to this Agreement, up to shares, for sale to the
Company's employees, officers and directors and other parties associated with
the Company (collectively, "Participants"), as set forth in the Prospectus (as
defined herein) under the heading "Underwriting" (the "Directed Share Program").
The Firm Securities to be sold by the Designated Underwriter pursuant to the
Directed Share Program (the "Directed Shares") will be sold by the Designated
Underwriter pursuant to this Agreement at the public offering price. Any
Directed Shares not orally confirmed for purchase by a Participant by the end of
the business day on which this Agreement is executed will be offered to the
public by the Designated Underwriter as set forth in the Prospectus. The Company
hereby agrees with the several Underwriters named in Schedule A hereto
("Underwriters") as follows:

     2.  Representations and Warranties of the Company. The Company represents
and warrants to, and agrees with, the several Underwriters that:

         (a)  A registration statement (No. 333-84033) relating to the Offered
     Securities, including a form of prospectus, has been filed with the
     Securities and Exchange Commission ("Commission") and either (i) has been
     declared effective under the Securities Act of 1933 ("Act") and is not
     proposed to be amended or (ii) is proposed to be amended by amendment or
     post-effective

                                       1


     amendment. If such registration statement ("initial registration
     statement") has been declared effective, either (i) an additional
     registration statement ("additional registration statement") relating to
     the Offered Securities may have been filed with the Commission pursuant to
     Rule 462(b) ("Rule 462(b)") under the Act and, if so filed, has become
     effective upon filing pursuant to such Rule and the Offered Securities all
     have been duly registered under the Act pursuant to the initial
     registration statement and, if applicable, the additional registration
     statement or (ii) such an additional registration statement is proposed to
     be filed with the Commission pursuant to Rule 462(b) and will become
     effective upon filing pursuant to such Rule and upon such filing the
     Offered Securities will all have been duly registered under the Act
     pursuant to the initial registration statement and such additional
     registration statement. If the Company does not propose to amend the
     initial registration statement or if an additional registration statement
     has been filed and the Company does not propose to amend it, and if any
     post-effective amendment to either such registration statement has been
     filed with the Commission prior to the execution and delivery of this
     Agreement, the most recent amendment (if any) to each such registration
     statement has been declared effective by the Commission or has become
     effective upon filing pursuant to Rule 462(c) ("Rule 462(c)") under the Act
     or, in the case of the additional registration statement, Rule 462(b). For
     purposes of this Agreement, "Effective Time" with respect to the initial
     registration statement or, if filed prior to the execution and delivery of
     this Agreement, the additional registration statement means (i) if the
     Company has advised the Representatives that it does not propose to amend
     such registration statement, the date and time as of which such
     registration statement, or the most recent post-effective amendment thereto
     (if any) filed prior to the execution and delivery of this Agreement, was
     declared effective by the Commission or has become effective upon filing
     pursuant to Rule 462(c), or (ii) if the Company has advised the
     Representatives that it proposes to file an amendment or post-effective
     amendment to such registration statement, the date and time as of which
     such registration statement, as amended by such amendment or post-effective
     amendment, as the case may be, is declared effective by the Commission. If
     an additional registration statement has not been filed prior to the
     execution and delivery of this Agreement but the Company has advised the
     Representatives that it proposes to file one, "Effective Time" with respect
     to such additional registration statement means the date and time as of
     which such registration statement is filed and becomes effective pursuant
     to Rule 462(b). "Effective Date" with respect to the initial registration
     statement or the additional registration statement (if any) means the date
     of the Effective Time thereof. The initial registration statement, as
     amended at its Effective Time, including all information contained in the
     additional registration statement (if any) and deemed to be a part of the
     initial registration statement as of the Effective Time of the additional
     registration statement pursuant to the General Instructions of the Form on
     which it is filed and including all information (if any) deemed to be a
     part of the initial registration statement as of its Effective Time
     pursuant to Rule 430A(b) ("Rule 430A(b)") under the Act, is hereinafter
     referred to as the "Initial Registration Statement". The additional
     registration statement, as amended at its Effective Time, including the
     contents of the initial registration statement incorporated by reference
     therein and including all information (if any) deemed to be a part of the
     additional registration statement as of its Effective Time pursuant to Rule
     430A(b), is hereinafter referred to as the "Additional Registration
     Statement". The Initial Registration Statement and the Additional
     Registration Statement are herein referred to collectively as the
     "Registration Statements" and individually as a "Registration Statement".
     The form of prospectus relating to the Offered Securities, as first filed
     with the Commission pursuant to and in accordance with Rule 424(b) ("Rule
     424(b)") under the Act or (if no such filing is required) as included in a
     Registration Statement, is hereinafter referred to as the "Prospectus". No
     document has been or will be prepared or distributed in reliance on Rule
     434 under the Act.

         (b)  If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement: (i) on the Effective
     Date of the Initial Registration Statement, the Initial Registration
     Statement conformed in all respects to the requirements of the Act and the
     rules

                                       2


     and regulations of the Commission ("Rules and Regulations") and did not
     include 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, (ii) on the Effective Date of the
     Additional Registration Statement (if any), each Registration Statement
     conformed, or will conform, in all respects to the requirements of the Act
     and the Rules and Regulations and did not include, or will not include, any
     untrue statement of a material fact and did not omit, or will not omit, to
     state any material fact required to be stated therein or necessary to make
     the statements therein not misleading and (iii) on the date of this
     Agreement, the Initial Registration Statement and, if the Effective Time of
     the Additional Registration Statement is prior to the execution and
     delivery of this Agreement, the Additional Registration Statement each
     conforms, and at the time of filing of the Prospectus pursuant to Rule
     424(b) or (if no such filing is required) at the Effective Date of the
     Additional Registration Statement in which the Prospectus is included, each
     Registration Statement and the Prospectus will conform, in all respects to
     the requirements of the Act and the Rules and Regulations, and neither of
     such documents includes, or will include, any untrue statement of a
     material fact or omits, or will omit, to state any material fact required
     to be stated therein or necessary to make the statements therein not
     misleading. If the Effective Time of the Initial Registration Statement is
     subsequent to the execution and delivery of this Agreement: on the
     Effective Date of the Initial Registration Statement, the Initial
     Registration Statement and the Prospectus will conform in all respects to
     the requirements of the Act and the Rules and Regulations, neither of such
     documents will include any untrue statement of a material fact or will omit
     to state any material fact required to be stated therein or necessary to
     make the statements therein not misleading, and no Additional Registration
     Statement has been or will be filed. The two preceding sentences do not
     apply to statements in or omissions from a Registration Statement or the
     Prospectus based upon written information furnished to the Company by any
     Underwriter through the Representatives specifically for use therein, it
     being understood and agreed that the only such information is that
     described as such in Section 7(b) hereof.

         (c)  The Company has been duly incorporated and is an existing
     corporation in good standing under the laws of the State of Delaware, with
     power and authority (corporate and other) to own its properties and conduct
     its business as described in the Prospectus; and the Company is duly
     qualified to do business as a foreign corporation in good standing in all
     other jurisdictions in which its ownership or lease of property or the
     conduct of its business requires such qualification and where failure to be
     so qualified would have a material adverse effect on the condition
     (financial or other), business, properties or results of operations of the
     Company and its subsidiaries taken as a whole (a "Material Adverse
     Effect").

         (d)  Each subsidiary of the Company has been duly incorporated and is
     an existing corporation in good standing under the laws of the jurisdiction
     of its incorporation, with power and authority (corporate and other) to own
     its properties and conduct its business as described in the Prospectus; and
     each subsidiary of the Company is duly qualified to do business as a
     foreign corporation in good standing in all other jurisdictions in which
     its ownership or lease of property or the conduct of its business requires
     such qualification and where failure to be so qualified would not have a
     Material Adverse Effect; all of the issued and outstanding capital stock of
     each subsidiary of the Company has been duly authorized and validly issued
     and is fully paid and nonassessable; and the capital stock of each
     subsidiary owned by the Company, directly or through subsidiaries, is owned
     free from liens, encumbrances and defects.

         (e)  The Offered Securities and all other outstanding shares of capital
     stock of the Company have been duly authorized; all outstanding shares of
     capital stock of the Company are, and, when the Offered Securities have

     Closing Date (as defined below), such Offered Securities will have been,
     validly issued, fully paid and nonassessable and will conform to the
     description thereof contained in the Prospectus; and the

                                       3


     stockholders of the Company have no preemptive rights with respect to the
     Securities which have not been waived or terminated on or prior to the
     Closing Date.

         (f)  Except as disclosed in the Prospectus, there are no contracts,
     agreements or understandings between the Company and any person that would
     give rise to a valid claim against the Company or any Underwriter for a
     brokerage commission, finder's fee or other like payment in connection with
     this offering.

         (g)  Except as disclosed in the Prospectus, there are no contracts,
     agreements or understandings between the Company and any person granting
     such person the right to require the Company to file a registration
     statement under the Act with respect to any securities of the Company owned
     or to be owned by such person or to require the Company to include such
     securities in the securities registered pursuant to a Registration
     Statement or in any securities being registered pursuant to any other
     registration statement filed by the Company under the Act.

         (h)  The Offered Securities have been approved for listing on the The
     Nasdaq Stock Market's National Market subject to notice of issuance.

     consummation of the transactions contemplated by this Agreement in
     connection with the issuance and sale of the Offered Securities by the
     Company, except such as have been obtained and made under the Act and such
     as may be required under state securities laws.

         (j)  The execution, delivery and performance of this Agreement, and the
     issuance and sale of the Offered Securities will not result in a breach or
     violation of any of the terms and provisions of, or constitute a default
     under, (i) any statute, any rule, regulation or order of any governmental
     agency or body or any court, domestic or foreign, having jurisdiction over
     the Company or any subsidiary of the Company or any of their properties, or
     (ii) any agreement or instrument to which the Company or any such
     subsidiary is a party or by which the Company or any such subsidiary is

     contemplated by this Agreement.

         (k)  This Agreement has been duly authorized, executed and delivered by
     the Company.

         (l)  Except as disclosed in the Prospectus, the Company and its
     subsidiaries have good and marketable title to all real properties and all
     other properties and assets owned by them, in each case free from liens,

     materially interfere with the use made or to be made thereof by them; and
     except as disclosed in the Prospectus, the Company and its subsidiaries
     hold any leased real or personal property under valid and enforceable
     leases with no exceptions that would materially interfere with the use made
     or to be made thereof by them.

         (m)  The Company and its subsidiaries possess adequate certificates,
     authorities or permits issued by appropriate governmental agencies or
     bodies necessary to conduct the business now operated by them and have not
     received any notice of proceedings relating to the revocation or
     modification of any such certificate, authority or permit that, if
     determined adversely to the Company or any of its subsidiaries, would
     individually or in the aggregate have a Material Adverse Effect.

                                       4


         (n)  No labor dispute with the employees of the Company or any
     subsidiary exists or, to the knowledge of the Company, is imminent that
     might have a Material Adverse Effect.

         (o)  The Company and its subsidiaries own, possess or can acquire on
     reasonable terms, adequate trademarks, trade names and other rights to
     inventions, know-how, patents, copyrights, confidential information and
     other intellectual property (collectively, "intellectual property rights")
     necessary to conduct the business now operated by them, or presently
     employed by them, and have not received any notice of infringement of or
     conflict with asserted rights of others with respect to any intellectual
     property rights that, if determined adversely to the Company or any of its
     subsidiaries, would individually or in the aggregate have a Material
     Adverse Effect.

         (p)  Except as disclosed in the Prospectus, neither the Company nor any
     of its subsidiaries is in violation of any statute, any rule, regulation,
     decision or order of any governmental agency or body or any court, domestic
     or foreign, relating to the use, disposal or release of hazardous or toxic
     substances or relating to the protection or restoration of the environment
     or human exposure to hazardous or toxic substances  (collectively,
     "environmental laws"), owns or operates any real property contaminated with
     any substance that is subject to any environmental laws, is liable for any
     off-site disposal or contamination pursuant to any environmental laws, or
     is subject to any claim relating to any environmental laws, which
     violation, contamination, liability or claim would individually or in the
     aggregate have a Material Adverse Effect; and the Company is not aware of
     any pending investigation which might lead to such a claim.

         (q)  Except as disclosed in the Prospectus, there are no pending
     actions, suits or proceedings against or affecting the Company, any of its
     subsidiaries or any of their respective properties that, if determined
     adversely to the Company or any of its subsidiaries, would individually or
     in the aggregate have a Material Adverse Effect, or would materially and
     adversely affect the ability of the Company to perform its obligations
     under this Agreement, or which are otherwise material in the context of the
     sale of the Offered Securities; and no such actions, suits or proceedings

     and the Prospectus present fairly the financial position of the Company and
     its consolidated subsidiaries as of the dates shown and their results of
     operations and cash flows for the periods shown, and, except as otherwise

     United States applied on a consistent basis and the schedules included in
     each Registration Statement present fairly the information required to be
     stated therein.

         (s)  Except as disclosed in the Prospectus, since the date of the

         (u)  Furthermore, the Company represents and warrants to the
     Underwriters that (i) the Registration Statement, the Prospectus and any
     preliminary prospectus comply, and any further amendments or supplements
     thereto will comply, with any applicable laws or regulations of foreign

                                       5


     jurisdictions in which the Prospectus or any preliminary prospectus, as
     amended or supplemented, if applicable, are distributed in connection with
     the Directed Share Program, and that (ii) no authorization, approval,
     consent, license, order, registration or qualification of or with any
     government, governmental instrumentality or court, other than such as have
     been obtained, is necessary under the securities law and regulations of
     foreign jurisdictions in which the Directed Shares are offered outside the
     United States.

         (v)  The Company has not offered, or caused the Underwriters to offer,
     any offered Securities to any person pursuant to the Directed Share Program
     with the specific intent to unlawfully influence (i) a customer or supplier
     of the Company to alter the customer's or supplier's level or type of
     business with the Company or (ii) a trade journalist or publication to
     write or publish favorable information about the Company or its products.


     3.  Purchase, Sale and Delivery of Offered Securities.  On the basis of the
representations, warranties and agreements herein contained, but subject to the
terms and conditions herein set forth, the Company agrees to sell to the
Underwriters, and the Underwriters agree, severally and not jointly, to purchase
from the Company, at a purchase price of $           per share, the respective
numbers of Firm Securities set forth opposite the names of the Underwriters in
Schedule A hereto.

     The Company will deliver the Firm Securities to the Representatives for the
accounts of the Underwriters, against payment of the purchase price in Federal
(same day) funds by official bank check or checks or wire transfer to an account
at a bank acceptable to Credit Suisse First Boston Corporation ("CSFBC") drawn
to the order of the Company at the office of Gunderson, Dettmer, Stough,
Villeneuve, Franklin & Hachigian, LLP ("Gunderson Detmer"), 155 Constitution
Drive, Menlo Park, California 94025, at      A.M., New York time, on
, or at such other time not later than seven full business days thereafter as
CSFBC and the Company determine, such time being herein referred to as the
"First Closing Date". For purposes of Rule 15c6-1 under the Securities Exchange
Act of 1934, the First Closing Date (if later than the otherwise applicable
settlement date) shall be the settlement date for payment of funds and delivery
of securities for all the Offered Securities sold pursuant to the offering. The
certificates for the Firm Securities so to be delivered will be in definitive
form, in such denominations and registered in such names as CSFBC requests and
will be made available for checking and packaging at the above office of
at least 24 hours prior to the First Closing Date.

     In addition, upon written notice from CSFBC given to the Company from time
to time not more than 30 days subsequent to the date of the Prospectus, the
Underwriters may purchase all or less than all of the Optional Securities at the
purchase price per share to be paid for the Firm Securities. The Company agrees
to sell to the Underwriters the number of Optional Securities specified in such
notice and the Underwriters agree, severally and not jointly, to purchase such
Optional Securities. Such Optional Securities shall be purchased for the account
of each Underwriter in the same proportion as the number of Firm Securities set
forth opposite such Underwriter's name bears to the total number of Firm
Securities (subject to adjustment by CSFBC to eliminate fractions) and may be
purchased by the Underwriters only for the purpose of covering over-allotments
made in connection with the sale of the Firm Securities. No Optional Securities
shall be sold or delivered unless the Firm Securities previously have been, or
simultaneously are, sold and delivered. The right to purchase the Optional
Securities or any portion thereof may be exercised from time to time and to the
extent not previously exercised may be surrendered and terminated at any time
upon notice by CSFBC to the Company.

     Each time for the delivery of and payment for the Optional Securities,
being herein referred to as an "Optional Closing Date", which may be the First
Closing Date (the First Closing Date and each Optional Closing Date, if any,
being sometimes referred to as a "Closing Date"), shall be determined by CSFBC
but shall be not later than five full business days after written notice of
election to purchase

                                       6


Optional Securities is given. The Company will deliver the Optional Securities
being purchased on each Optional Closing Date to the Representatives for the
accounts of the several Underwriters, against payment of the purchase price
therefor in Federal (same day) funds by official bank check or checks or wire
transfer to an account at a bank acceptable to CSFBC drawn to the order of the
Company, at the above office of Gunderson Detmer. The certificates for the
Optional Securities being purchased on each Optional Closing Date will be in
definitive form, in such denominations and registered in such names as CSFBC
requests upon reasonable notice prior to such Optional Closing Date and will be
made available for checking and packaging at the above office of
at a reasonable time in advance of such Optional Closing Date.

     4.  Offering by Underwriters.  It is understood that the several
Underwriters propose to offer the Offered Securities for sale to the public as
set forth in the Prospectus.

     5.  Certain Agreements of the Company. The Company agrees with the several
Underwriters that:

         (a)  If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement, the Company will
     file the Prospectus with the Commission pursuant to and in accordance with
     subparagraph (1) (or, if applicable and if consented to by CSFBC,
     subparagraph (4)) of Rule 424(b) not later than the earlier of (A) the
     second business day following the execution and delivery of this Agreement
     or (B) the fifteenth business day after the Effective Date of the Initial
     Registration Statement.

     The Company will advise CSFBC promptly of any such filing pursuant to Rule
     424(b). If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement and an additional
     registration statement is necessary to register a portion of the Offered
     Securities under the Act but the Effective Time thereof has not occurred as
     of such execution and delivery, the Company will file the additional
     registration statement or, if filed, will file a post-effective amendment
     thereto with the Commission pursuant to and in accordance with Rule 462(b)
     on or prior to 10:00 P.M., New York time, on the date of this Agreement or,
     if earlier, on or prior to the time the Prospectus is printed and
     distributed to any Underwriter, or will make such filing at such later date
     as shall have been consented to by CSFBC.

         (b)  The Company will advise CSFBC promptly of any proposal to amend or
     supplement the initial or any additional registration statement as filed or
     the related prospectus or the Initial Registration Statement, the
     Additional Registration Statement (if any) or the Prospectus and will not
     effect such amendment or supplementation without CSFBC's consent; and the
     Company will also advise CSFBC promptly of the effectiveness of each
     Registration Statement (if its Effective Time is subsequent to the
     execution and delivery of this Agreement) and of any amendment or
     supplementation of a Registration Statement or the Prospectus and of the
     institution by the Commission of any stop order proceedings in respect of a
     Registration Statement and will use its best efforts to prevent the
     issuance of any such stop order and to obtain as soon as possible its
     lifting, if issued.

         (c)  If, at any time when a prospectus relating to the Offered
     Securities is required to be delivered under the Act in connection with
     sales by any Underwriter or dealer, any event occurs 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
     to make the statements therein, in the light of the circumstances under
     which they were made, not misleading, or if it is necessary at any time to
     amend the Prospectus to comply with the Act, the Company will promptly
     notify CSFBC of such event and will promptly prepare and file with the
     Commission, at its own expense, an amendment or supplement which will
     correct such statement or omission or an amendment which will effect such
     compliance. Neither CSFBC's consent to, nor the Underwriters'

                                       7


     delivery of, any such amendment or supplement shall constitute a waiver of
     any of the conditions set forth in Section 6.

         (d)  As soon as practicable, but not later than the Availability Date
     (as defined below), the Company will make generally available to its
     securityholders an earnings statement covering a period of at least 12
     months beginning after the Effective Date of the Initial Registration
     Statement (or, if later, the Effective Date of the Additional Registration
     Statement) which will satisfy the provisions of Section 11(a) of the Act.
     For the purpose of the preceding sentence, "Availability Date" means the
     45th day after the end of the fourth fiscal quarter following the fiscal
     quarter that includes such Effective Date, except that, if such fourth
     fiscal quarter is the last quarter of the Company's fiscal year,
     "Availability Date" means the 90th day after the end of such fourth fiscal
     quarter.

         (e)  The Company will furnish to the Representatives copies of each
     Registration Statement (five of which will be signed and will include all
     exhibits), each related preliminary prospectus, and, so long as a
     prospectus relating to the Offered Securities is required to be delivered
     under the Act in connection with sales by any Underwriter or dealer, the
     Prospectus and all amendments and supplements to such documents, in each
     case in such quantities as CSFBC reasonably requests. The Prospectus shall
     be so furnished on or prior to 3:00 P.M., New York time, on the business
     day following the later of the execution and delivery of this Agreement or
     the Effective Time of the Initial Registration Statement. All other
     documents shall be so furnished as soon as available. The Company will pay
     the expenses of printing and distributing to the Underwriters all such
     documents.

         (f)  The Company will arrange for the qualification of the Offered
     Securities for sale under the laws of such jurisdictions as CSFBC
     designates and will continue such qualifications in effect so long as
     required for the distribution; provided, however, that the Company will not
     be required to arrange for the qualification of the Offered Securities in
     any jurisdiction in which the Company would, as a result of such
     qualification, be required to qualify to do business as a foreign
     corporation or to execute a general consent to service of process effecting
     such qualification.

         (g)  During the period of five years hereafter, the Company will
     furnish to the Representatives and, upon request, to each of the other
     Underwriters, as soon as practicable after the end of each fiscal year, a
     copy of its annual report to stockholders for such year; and the Company
     will furnish to the Representatives (i) as soon as available, a copy of
     each report and any definitive proxy statement of the Company filed with
     the Commission under the Securities Exchange Act of 1934 or mailed to
     stockholders, and (ii) from time to time, such other information concerning
     the Company as CSFBC may reasonably request.

         (h)  The Company will pay all expenses incident to the performance of
     its obligations under this Agreement, for any filing fees and other
     expenses (including fees and disbursements of counsel) incurred in
     connection with qualification of the Offered Securities for sale under the
     laws of such jurisdictions as CSFBC designates and the printing of
     memoranda relating thereto, for the filing fee incident to, and the
     reasonable fees and disbursements of counsel to the Underwriters in
     connection with, the review by the National Association of Securities
     Dealers, Inc. of the Offered Securities, for any travel expenses of the
     Company's officers and employees and any other expenses of the Company in
     connection with attending or hosting meetings with prospective purchasers
     of the Offered Securities (except as otherwise agreed in writing) and for
     expenses incurred in distributing preliminary prospectuses and the
     Prospectus (including any amendments and supplements thereto) to the
     Underwriters.

                                       8


         (i)  For a period of 180 days after the date of the initial public
     offering of the Offered Securities, the Company will not offer, sell,
     contract to sell, pledge or otherwise dispose of, directly or indirectly,
     or file with the Commission a registration statement under the Act relating
     to, any additional shares of its Securities or securities convertible into
     or exchangeable or exercisable for any shares of its Securities, or
     publicly disclose the intention to make any such offer, sale, pledge,
     disposition or filing, without the prior written consent of CSFBC except
     issuances of Securities pursuant to the conversion or exchange of
     convertible or exchangeable securities or the exercise of warrants or
     options, in each case outstanding on the date hereof, grants of employee
     and director stock options or employee stock purchases pursuant to the
     terms of plans in effect on the date hereof or issuances of Securities
     pursuant to the exercise of such options.

         (j)  The Company agrees to use reasonable best efforts to cause all
     directors, officers, and stockholders to agree that, without the prior
     written consent of CSFBC on behalf of the Underwriters, such person or
     entity will not, for a period of 180 days following the commencement of the
     public offering of the Offered Securities by the Underwriters, directly or
     indirectly, sale, make any short sale of, grant any option for the purchase
     of, or otherwise transfer or dispose of, any of such Securities, or any
     such securities convertible into or exercisable or exchangeable for
     Securities.

         (k)  The Company agrees to use reasonable best efforts to cause each
     person who acquires Securities of the Company pursuant to the exercise of
     any option, including but not limited to options granted under the
     Company's 1992 Stock Plan, 1995 Stock Plan, 1999 Equity Incentive Plan,
     1999 Non-Employee Directors Option Plan and 1999 Employee Stock Purchase
     Plan to sign an agreement that restricts such person from selling, making
     any short sale of, granting any option for the purchase of, or otherwise
     transferring or disposing of, any of such Securities, or any such
     securities convertible into or exercisable or exchangeable for Securities,
     for a period of 180 days after the date of the Prospectus without the prior
     written consent of CSFBC; and the Company will issue and impose a stop-
     transfer instruction with the Company's transfer agent in order to enforce
     the foregoing lock-up agreements.

         (l)  The Company will (i) use reasonable best efforts to enforce the
     terms of each agreement described in paragraphs (j) and (k) of this Section
     5 and each other similar "lock-up" and "market standoff" provision
     contained in any agreement pursuant to which any Securities have been
     acquired from the Company (each a "Lock-up Agreement"), and (ii) issue
     stop-transfer instructions to the transfer agent for the Securities with
     respect to any transaction or contemplated transaction that would
     constitute a breach or a default under the applicable Lock-up Agreement. In
     addition, except with the prior written consent of CSFBC, the Company
     agrees (i) not to amend or terminate, or waive any right under, any Lock-up
     Agreement, or take any other action that would directly or indirectly have
     the same effect as an amendment or termination, or waiver of any right
     under any Lock-up Agreement, that would permit any holder of Securities, or
     any securities convertible into, or exercisable or exchangeable for,
     Securities, to make any short sale of, grant any option for the purchase
     of, or otherwise transfer or dispose of, any such Securities or other
     securities, prior to the expiration of the 180 days after the date of the
     Prospectus and (ii) not to consent to any sale, short sale, grant of an
     option for the purchase of, or other disposition or transfer of shares of
     Securities, or securities convertible into or exercisable or exchangeable
     for Securities, subject to a Lock-up Agreement.

         (m)  In connection with the Directed Share Program, the Company will
     ensure that the Directed Shares will be restricted to the extent required
     by the National Association of Securities Dealers, Inc. (the "NASD") or the
     NASD rules from sale, transfer, assignment, pledge or hypothecation for a
     period of three months following the date of the effectiveness of the
     Registration Statement.  The Designated Underwriter will notify the Company
     as to which

                                       9


     Participants will need to be so restricted. The Company will
     direct the transfer agent to place stop transfer restrictions upon such
     securities for such period of time.

         (n)  The Company will pay all fees and disbursements of counsel
     incurred by the Underwriters in connection with the Directed Shares Program
     and stamp duties, similar taxes or duties or other taxes, if any, incurred
     by the underwriters in connection with the Directed Share Program.

         Furthermore, the Company covenants with the Underwriters that the
     Company will comply with all applicable securities and other applicable
     laws, rules and regulations in each foreign jurisdiction in which the
     Directed Shares are offered in connection with the Directed Share Program.

     6.  Conditions of the Obligations of the Underwriters. The obligations of
the several Underwriters to purchase and pay for the Firm Securities on the
First Closing Date and the Optional Securities to be purchased on each Optional
Closing Date will be subject to the accuracy of the representations and
warranties on the part of the Company herein, to the accuracy of the statements
of Company officers made pursuant to the provisions hereof, to the performance
by the Company of its obligations hereunder and to the following additional
conditions precedent:

         (a)  The Representatives shall have received a letter, dated the date
     of delivery thereof (which, if the Effective Time of the Initial
     Registration Statement is prior to the execution and delivery of this
     Agreement, shall be on or prior to the date of this Agreement or, if the
     Effective Time of the Initial Registration Statement is subsequent to the
     execution and delivery of this Agreement, shall be prior to the filing of
     the amendment or post-effective amendment to the registration statement to
     be filed shortly prior to such Effective Time), of Ernst & Young LLP
     confirming that they are independent public accountants within the meaning
     of the Act and the applicable published Rules and Regulations thereunder
     and stating to the effect that:

              (i)   in their opinion the financial statements and schedules
          examined by them and included in the Registration Statements comply as
          to form in all material respects with the applicable accounting
          requirements of the Act and the related published Rules and
          Regulations;

              (ii)  they have performed the procedures specified by the American
          Institute of Certified Public Accountants for a review of interim
          financial information as described in Statement of Auditing Standards
          No. 71, Interim Financial Information, on the unaudited financial
          statements included in the Registration Statements;

              (iii) on the basis of the review referred to in clause (ii) above,
          a reading of the latest available interim financial statements of the
          Company, inquiries of officials of the Company who have responsibility
          for financial and accounting matters and other specified procedures,
          nothing came to their attention that caused them to believe that:

                    (A) the unaudited financial statements included in the
               Registration Statements do not comply as to form in all material
               respects with the applicable accounting requirements of the Act
               and the related published Rules and Regulations or any material
               modifications should be made to such unaudited financial
               statements for them to be in conformity with generally accepted
               accounting principles;

                    (B) at the date of the latest available balance sheet read
               by such accountants, or at a subsequent specified date not more
               than three business days

                                       10


               prior to the date of such letter, there was any change in the
               capital stock or any increase in short-term indebtedness or long-
               term debt of the Company and its consolidated subsidiaries or, at
               the date of the latest available balance sheet read by such
               accountants, there was any decrease in consolidated total current
               assets or net assets, as compared with amounts shown on the
               latest balance sheet included in the Prospectus; or

                    (C) for the period from the closing date of the latest
               income statement included in the Prospectus to the closing date
               of the latest available income statement read by such accountants
               there were any decreases, as compared with the corresponding
               period of the previous year and with the period of corresponding
               length ended the date of the latest income statement included in
               the Prospectus, in consolidated total revenues or any increase in
               loss from operations or any increase in the total or per share
               amounts of consolidated net loss.

          except in all cases set forth in clauses (B) and (C) above for
          changes, increases or decreases which the Prospectus discloses have
          occurred or may occur or which are described in such letter; and

          (iv) they have compared specified dollar amounts (or percentages
          derived from such dollar amounts) and other financial information
          contained in the Registration Statements (in each case to the extent
          that such dollar amounts, percentages and other financial information
          are derived from the general accounting records of the Company and its
          subsidiaries subject to the internal controls of the Company's
          accounting system or are derived directly from such records by
          analysis or computation) with the results obtained from inquiries, a
          reading of such general accounting records and other procedures
          specified in such letter and have found such dollar amounts,
          percentages and other financial information to be in agreement with
          such results, except as otherwise specified in such letter.

     For purposes of this subsection, (i) if the Effective Time of the Initial
     Registration Statement is subsequent to the execution and delivery of this
     Agreement, "Registration Statements" shall mean the initial registration
     statement as proposed to be amended by the amendment or post-effective
     amendment to be filed shortly prior to its Effective Time, (ii) if the
     Effective Time of the Initial Registration Statement is prior to the
     execution and delivery of this Agreement but the Effective Time of the
     Additional Registration is subsequent to such execution and delivery,
     "Registration Statements" shall mean the Initial Registration Statement and
     the additional registration statement as proposed to be filed or as
     proposed to be amended by the post-effective amendment to be filed shortly
     prior to its Effective Time, and (iii) "Prospectus" shall mean the
     prospectus included in the Registration Statements.

          (b)  If the Effective Time of the Initial Registration Statement is
     not prior to the execution and delivery of this Agreement, such Effective
     Time shall have occurred not later than 10:00 P.M., New York time, on the
     date of this Agreement or such later date as shall have been consented to
     by CSFBC. If the Effective Time of the Additional Registration Statement
     (if any) is not prior to the execution and delivery of this Agreement, such
     Effective Time shall have occurred not later than 10:00 P.M., New York
     time, on the date of this Agreement or, if earlier, the time the Prospectus
     is printed and distributed to any Underwriter, or shall have occurred at
     such later date as shall have been consented to by CSFBC. If the Effective
     Time of the Initial Registration Statement is prior to the execution and
     delivery of this Agreement, the Prospectus shall have been filed with the
     Commission in accordance with the Rules and Regulations and Section 5(a) of
     this Agreement. Prior to such Closing Date, no stop order suspending the
     effectiveness of a Registration Statement

                                       11


     shall have been issued and no proceedings for that purpose shall have been
     instituted or, to the knowledge of the Company or the Representatives,
     shall be contemplated by the Commission.

          (c)  Subsequent to the execution and delivery of this Agreement, there
     shall not have occurred (i) any change, or any development or event
     involving a prospective change, in the condition (financial or other),
     business, properties or results of operations of the Company and its
     subsidiaries taken as one enterprise which, in the judgment of a majority
     in interest of the Underwriters including the Representatives, is material
     and adverse and makes it impractical or inadvisable to proceed with
     completion of the public offering or the sale of and payment for the
     Offered Securities; (ii) any material suspension or material limitation of
     trading in securities generally on the New York Stock Exchange or any
     setting of minimum prices for trading on such exchange, or any suspension
     of trading of any securities of the Company on any exchange or in the over-
     the-counter market; (iii) any banking moratorium declared by U.S. Federal
     or New York authorities; or (iv) any outbreak or escalation of major
     hostilities in which the United States is involved, any declaration of war
     by Congress or any other substantial national or international calamity or
     emergency if, in the judgment of a majority in interest of the Underwriters
     including the Representatives, the effect of any such outbreak, escalation,
     declaration, calamity or emergency makes it impractical or inadvisable to
     proceed with completion of the public offering or the sale of and payment
     for the Offered Securities.

          (d)  The Representatives shall have received an opinion, dated such
     Closing Date, of Gunderson, Dettmer, Stough, Villeneuve, Franklin &
     Hachigian, LLP, counsel for the Company, to the effect that:

               (i)   The Company has been duly incorporated and is an existing
          corporation in good standing under the laws of the State of Delaware,
          with corporate power and authority to own its properties and conduct
          its business as described in the Prospectus; and the Company is duly
          qualified to do business as a foreign corporation in good standing in
          all other jurisdictions in which its ownership or lease of property or
          the conduct of its business requires such qualification;

               (ii)  The Offered Securities delivered on such Closing Date and
          all other outstanding shares of the Common Stock of the Company have
          been duly authorized and validly issued, are fully paid and
          nonassessable and conform to the description thereof contained in the
          Prospectus; and the stockholders of the Company have no preemptive
          rights with respect to the Securities;

               (iii) Except as disclosed in the Prospectus, there are no
          contracts, agreements or understandings known to such counsel between
          the Company and any person granting such person the right to require
          the Company to file a registration statement under the Act with
          respect to any securities of the Company owned or to be owned by such
          person or to require the Company to include such securities in the
          securities registered pursuant to the Registration Statement or in any
          securities being registered pursuant to any other registration
          statement filed by the Company under the Act;

               (iv)  The Company is not and, after giving effect to the offering
          and sale of the Offered Securities and the application of the proceeds
          thereof as described in the Prospectus, will not be an "investment
          company" as defined in the Investment Company Act of 1940;

               (v)   No consent, approval, authorization or order of, or filing
          with, any governmental agency or body or any court is required for the
          consummation of the

                                       12


          transactions contemplated by this Agreement in connection with the
          issuance or sale of the Offered Securities by the Company, except such
          as have been obtained and made under the Act and such as may be
          required under state securities laws;

               (vi)   The execution, delivery and performance of this Agreement
          and the issuance and sale of the Offered Securities will not result in
          a breach or violation of any of the terms and provisions of, or
          constitute a default under, any statute, any rule, regulation or order
          of any governmental agency or body or any court having jurisdiction
          over the Company or any subsidiary of the Company or any of their
          properties, or any agreement or instrument to which the Company or any
          such subsidiary is a party or by which the Company or any such
          subsidiary is bound or to which any of the properties of the Company
          or any such subsidiary is subject, or the charter or by-laws of the
          Company or any such subsidiary, and the Company has full power and
          authority to authorize, issue and sell the Offered Securities as
          contemplated by this Agreement;

               (vii)  The Initial Registration Statement was declared effective
          under the Act as of the date and time specified in such opinion, the
          Additional Registration Statement (if any) was filed and became
          effective under the Act as of the date and time (if determinable)
          specified in such opinion, the Prospectus either was filed with the
          Commission pursuant to the subparagraph of Rule 424(b) specified in
          such opinion on the date specified therein or was included in the
          Initial Registration Statement or the Additional Registration
          Statement (as the case may be), and, to the best of the knowledge of
          such counsel, no stop order suspending the effectiveness of a
          Registration Statement or any part thereof has been issued and no
          proceedings for that purpose have been instituted or are pending or
          contemplated under the Act, and each Registration Statement and the
          Prospectus, and each amendment or supplement thereto, as of their
          respective effective or issue dates, complied as to form in all
          material respects with the requirements of the Act and the Rules and
          Regulations;

               (viii) The statements set forth under the heading "Description of
          Capital Stock" in the Prospectus, insofar as such statements purport
          to summarize certain provisions of the capital stock of the Company,
          provide an accurate and fair summary of such provisions; the
          statements set forth under the headings "Management--Employment
          Benefit Plans," "Management--Change in Control Agreements," and
          "Shares Eligible for Future Sale" in the Prospectus, insofar as such
          statements constitute a summary of legal matters, documents or
          proceedings referred to therein, have been reviewed by such counsel
          and accurately and fairly present the information called for with
          respect to such legal matters, documents and proceedings as required
          by the Act and the rules and regulations thereunder; and the
          descriptions in the Registration Statement and Prospectus of statutes,
          legal and governmental proceedings and contracts and other documents
          are accurate and fairly present the information required to be shown;
          and

               (ix)   This Agreement has been duly authorized, executed and
          delivered by the Company.

     Such opinion shall also contain a statement to the effect that such counsel
     participated in meetings at which representatives of the Underwriters,
     their legal counsel, and the Company were present, and based on such
     meetings, such counsel has no reason to believe that any part of a
     Registration Statement or any amendment thereto, as of its effective date
     or as of such Closing Date, contained any

                                       13


     untrue statement of a material fact or omitted to state any material fact
     required to be stated therein or necessary to make the statements therein
     not misleading or that the Prospectus or any amendment or supplement
     thereto, as of its issue date or as of such Closing Date, contained any
     untrue statement of a material fact or omitted to state any material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; and such counsel
     do not know of any legal or governmental proceedings required to be
     described in a Registration Statement or the Prospectus which are not
     described as required, or of any contracts or documents of a character
     required to be described in a Registration Statement or to be filed as
     exhibits to a Registration Statement which are not described and filed as
     required; it being understood that such counsel expresses no statement as
     to the financial statements and the notes thereto, financial schedules,
     other financial data and statistical data derived therefrom.

          (e)  The Representatives shall have received from Fenwick & West LLP,
     counsel for the Underwriters, such opinion or opinions, dated such Closing
     Date, with respect to the incorporation of the Company, the validity of the
     Offered Securities delivered on such Closing Date, the Registration
     Statements, the Prospectus and other related matters as the Representatives
     may require, and the Company shall have furnished to such counsel such
     documents as they request for the purpose of enabling them to pass upon
     such matters.

          (f)  The Representatives shall have received a certificate, dated such
     Closing Date, of the President or any Vice President and a principal
     financial or accounting officer of the Company in which such officers, to
     the best of their knowledge after reasonable investigation, shall state
     that: the representations and warranties of the Company in this Agreement
     are true and correct; the Company has complied with all agreements and
     satisfied all conditions on its part to be performed or satisfied hereunder
     at or prior to such Closing Date; no stop order suspending the
     effectiveness of any Registration Statement has been issued and no
     proceedings for that purpose have been instituted or are contemplated by
     the Commission; the Additional Registration Statement (if any) satisfying
     the requirements of subparagraphs (1) and (3) of Rule 462(b) was filed
     pursuant to Rule 462(b), including payment of the applicable filing fee in
     accordance with Rule 111(a) or (b) under the Act, prior to the time the
     Prospectus was printed and distributed to any Underwriter; and, subsequent
     to the date of the most recent financial statements in the Prospectus,
     there has been no material adverse change, nor any development or event
     involving a prospective material adverse change, in the condition
     (financial or other), business, properties or results of operations of the
     Company and its subsidiaries taken as a whole except as set forth in or
     contemplated by the Prospectus or as described in such certificate.

          (g)  The Representatives shall have received a letter, dated such
     Closing Date, of Ernst & Young LLP which meets the requirements of
     subsection (a) of this Section, except that the specified date referred to
     in such subsection will be a date not more than three days prior to such
     Closing Date for the purposes of this subsection.

          (h)  The Representatives shall have received an opinion, dated such
     Closing Date, of Finnegan and Henderson, intellectual property counsel for
     the Company, to the effect that:

               (i)  Such counsel are familiar with the technology used by the
          Company in its business and the manner of its use thereof and have
          read the Registration Statements and the Prospectus, including
          particularly the portions of the Registration Statements and the
          Prospectus referring to patents, trade secrets, trademarks, service
          marks or other proprietary information or materials;

               (ii) The Company is listed in the records of the United States
          Patent and Trademark Office as the holder of record of the patents
          listed on a schedule to such opinion (the "Patents") and each of the
          applications listed on a schedule to such opinion (the
          "Applications"). To the knowledge of such counsel, there are no claims
          of third parties to any ownership interest or lien with respect to any
          of the Patents or Applications.

                                       14


          Such counsel is not aware of any material defect in form in the
          preparation or filing of the Applications on behalf of the Company. To
          the knowledge of such counsel, the Applications are being pursued by
          the Company. To the knowledge of such counsel, the Company owns as its
          sole property the Patents and pending Applications;

               (iii) The Company is listed in the records of the appropriate
          foreign offices as the sole holder of record of the foreign patents
          listed on a schedule to such opinion (the "Foreign Patents") and each
          of the applications listed on a schedule to such opinion (the "Foreign
          Applications"). Such counsel knows of no claims of third parties to
          any ownership interest or lien with respect to the Foreign Patents or
          Foreign Applications. Such counsel is not aware of any material defect
          of form in the preparation or filing of the Foreign Applications on
          behalf of the Company. To the knowledge of such counsel, the Foreign
          Applications are being pursued by the Company. To the knowledge of
          such counsel, the Company owns as its sole property the Foreign
          Patents and pending Foreign Applications;

               (iv)  Such counsel knows of no reason why the Patents or Foreign
          Patents are not valid as issued.  Such counsel has no knowledge of any
          reason why any patent to be issued as a result of any Application or
          Foreign Application would not be valid or would not afford the Company
          useful patent protection with respect thereto;

               (v)   As to the statements under the captions "Risk Factors--We
          and our licensees may be found to infringe proprietary rights of
          others, resulting in litigation, redesign expenses, or costly
          licenses.", "Risk Factors--Protection of our intellectual property is
          limited and efforts to protect our intellectual property may be
          inadequate, time consuming, and expensive." and "Business--
          Intellectual Property," nothing has come to the attention of such
          counsel which caused them to believe that the above-mentioned sections
          of any Registration Statement or any amendment thereto, as of its
          effective date or as of such Closing Date, contained any untrue
          statement of a material fact or omitted to state any material fact
          required to be stated therein or necessary to make the statements
          therein not misleading or that the Prospectus or any amendment or
          supplement thereto, as of its issue date or as of the Closing Date or
          any Optional Closing Date, contained any untrue statement of a
          material fact or omitted to state any material fact necessary in order
          to make the statements therein, in the light of the circumstances
          under which they were made, not misleading, or at the Closing Date or
          any Optional Closing Date, the above-mentioned sections in the
          Prospectus or any amendment or supplement thereto contained any untrue
          statement of a material fact or omitted to state a material fact
          required to be stated therein or necessary to make the statements
          therein, in light of the circumstances under which they were made, not
          misleading; and

               (vi)  Such counsel knows of no material action, suit, claim or
          proceeding relating to patents, patent rights or licenses, trademarks
          or trademark rights, copyrights, collaborative research, licenses or
          royalty arrangements or agreements or trade secrets, know-how or
          proprietary techniques, including processes and substances, owned by
          or affecting the business or operations of the Company which are
          pending or threatened against the Company or any of its officers or
          directors.

The Company will furnish the Representatives with such conformed copies of such
opinions, certificates, letters and documents as the Representatives reasonably
request.  CSFBC may in its sole discretion waive on behalf of the Underwriters
compliance with any conditions to the obligations of the Underwriters hereunder,
whether in respect of an Optional Closing Date or otherwise.

                                       15


     7.  Indemnification and Contribution.  (a)  The Company will indemnify and
hold harmless each Underwriter, its partners, directors and officers and each
person, if any, who controls such Underwriter within the meaning of Section 15
of the Act, 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 any untrue statement or alleged
untrue statement of any material fact contained in any Registration Statement,
the Prospectus, or any amendment or supplement thereto, or any related
preliminary prospectus, 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 loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that the Company will 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 in or omission or alleged omission from
any of such documents in reliance upon and in conformity with written
information furnished to the Company by any Underwriter through the
Representatives specifically for use therein, it being understood and agreed
that the only such information furnished by any Underwriter consists of the
information described as such in subsection (b) below.


     The Company agrees to indemnify and hold harmless the Designated
Underwriter and each person, if any, who controls the Designated Underwriter
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act (the "Designated Entities"), from and against any and all
losses, claims, damages and liabilities (including, without limitation, any
legal or other expenses reasonably incurred in connection with defending or
investigating any such action or claim) (i) caused by any untrue statement or
alleged untrue statement of a material fact contained in any material prepared
by or with the consent of the Company for distribution to Participants in
connection with the Directed Share Program or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading; (ii) caused by the
failure of any Participant to pay for and accept delivery of Directed Shares
that the Participant agreed to purchase; or (iii) related to, arising out of, or
in connection with the Directed Share Program, other than losses, claims,
damages or liabilities (or expenses relating thereto) that are finally
judicially determined to have resulted from the bad faith or gross negligence of
the Designated Entities.

     (b)  Each Underwriter will severally and not jointly indemnify and hold
harmless the Company, its directors and officers and each person, if any who
controls the Company within the meaning of Section 15 of the Act, against any
losses, claims, damages or liabilities to which the Company 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 any
untrue statement or alleged untrue statement of any material fact contained in
any Registration Statement, the Prospectus, or any amendment or supplement
thereto, or any related preliminary prospectus, or arise out of or are based
upon the omission or the 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 reliance upon and in conformity with written information furnished to the
Company by such Underwriter through the Representatives specifically for use
therein, and will reimburse any legal or other expenses reasonably incurred by
the Company in connection with investigating or defending any such loss, claim,
damage, liability or action as such expenses are incurred, it being understood
and agreed that the only such information furnished by any Underwriter consists
of the following information in the Prospectus furnished on behalf of each
Underwriter:  the concession and reallowance figures appearing in the
paragraph under the caption "Underwriting" and the information contained in the
paragraph under the caption "Underwriting."

     (c)  Promptly after receipt by an indemnified party under this Section of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against

                                       16


the indemnifying party under subsection (a) or (b) above, notify the
indemnifying party of the commencement thereof; but the omission so to notify
the indemnifying party will not relieve it from any liability which it may have
to any indemnified party otherwise than under subsection (a) or (b) above. In
case any such action is brought against any indemnified party and it notifies
the indemnifying party of the commencement thereof, the indemnifying party will
be entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (who 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 will
not be liable to such indemnified party under this Section for any legal or
other expenses subsequently incurred by such indemnified party in connection
with the defense thereof other than reasonable costs of investigation.
Notwithstanding anything contained herein to the contrary, if indemnity may be
sought pursuant to the last paragraph in Section 7 (a) hereof in respect of such
action or proceeding, then in addition to such separate firm for the indemnified
parties, the indemnifying party shall be liable for the reasonable fees and
expenses of not more than one separate firm (in addition to any local counsel)
for the Designated Underwriter for the defense of any losses, claims, damages
and liabilities arising out of the Directed Share Program, and all persons, if
any, who control the Designated Underwriter within the meaning of either Section
15 of the Act of Section 20 of the Exchange Act. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened action in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party unless such settlement (i) includes
an unconditional release of such indemnified party from all liability on any
claims that are the subject matter of such action 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 an indemnified party.

     (d)  If the indemnification provided for in this Section is unavailable or
insufficient to hold harmless an indemnified party under subsection (a) or (b)
above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in subsection (a) or (b) above (i) in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and the Underwriters on the other from the offering of the Securities
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 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 as well as any other relevant equitable considerations. The relative
benefits received by the Company on the one hand and the Underwriters on the
other shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting expenses) received by the Company bear to
the total underwriting discounts and commissions received by the Underwriters.
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 Underwriters and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The amount paid by an indemnified party as a
result of the losses, claims, damages or liabilities referred to in the first
sentence of this subsection (d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any action or claim which is the subject of this
subsection (d). Notwithstanding the provisions of this subsection (d), no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Securities 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 (d) to contribute are several in proportion to their respective
underwriting obligations and not joint.

                                       17


     (e)  The obligations of the Company under this Section shall be in addition
to any liability which the Company may otherwise have and shall extend, upon the
same terms and conditions, to each person, if any, who controls any Underwriter
within the meaning of the Act; and the obligations of the Underwriters under
this Section 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 director of the Company, to each officer of the Company who
has signed a Registration Statement and to each person, if any, who controls the
Company within the meaning of the Act.

     8.  Default of Underwriters.  If any Underwriter or Underwriters default in
their obligations to purchase Offered Securities hereunder on either the First
or any Optional Closing Date and the aggregate number of shares of Offered
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase does not exceed 10% of the total number of shares of Offered Securities
that the Underwriters are obligated to purchase on such Closing Date, CSFBC may
make arrangements satisfactory to the Company for the purchase of such Offered
Securities by other persons, including any of the Underwriters, but if no such
arrangements are made by such Closing Date, the non-defaulting Underwriters
shall be obligated severally, in proportion to their respective commitments
hereunder, to purchase the Offered Securities that such defaulting Underwriters
agreed but failed to purchase on such Closing Date. If any Underwriter or
Underwriters so default and the aggregate number of shares of Offered Securities
with respect to which such default or defaults occur exceeds 10% of the total
number of shares of Offered Securities that the Underwriters are obligated to
purchase on such Closing Date and arrangements satisfactory to CSFBC and the
Company for the purchase of such Offered Securities by other persons are not
made within 36 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting Underwriter or the Company, except
as provided in Section 9 (provided that if such default occurs with respect to
Optional Securities after the First Closing Date, this Agreement will not
terminate as to the Firm Securities or any Optional Securities purchased prior
to such termination). As used in this Agreement, the term "Underwriter" includes
any person substituted for an Underwriter under this Section. Nothing herein
will relieve a defaulting Underwriter from liability for its default.

     9.  Survival of Certain Representations and Obligations.  The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the several Underwriters set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation, or statement as to the results thereof, made by or on behalf
of any Underwriter, the Company or any of their respective representatives,
officers or directors or any controlling person, and will survive delivery of
and payment for the Offered Securities. If this Agreement is terminated pursuant
to Section 8 or if for any reason the purchase of the Offered Securities by the
Underwriters is not consummated, the Company shall remain responsible for the
expenses to be paid or reimbursed by it pursuant to Section 5 and the respective
obligations of the Company and the Underwriters pursuant to Section 7 shall
remain in effect, and if any Offered Securities have been purchased hereunder
the representations and warranties in Section 2 and all obligations under
Section 5 shall also remain in effect. If the purchase of the Offered Securities
by the Underwriters is not consummated for any reason other than solely because
of the termination of this Agreement pursuant to Section 8 or the occurrence of
any event specified in clause (iii), (iv) or (v) of Section 6(c), the Company
will reimburse the Underwriters for all out-of-pocket expenses (including fees
and disbursements of counsel) reasonably incurred by them in connection with the
offering of the Offered Securities.

     10. Notices. All communications hereunder will be in writing and, if sent
to the Underwriters, will be mailed, delivered or telegraphed and confirmed to
the Representatives c/o Credit Suisse First Boston Corporation, Eleven Madison
Avenue, New York, N.Y. 10010-3629, Attention: Investment Banking Department--

however, that any notice to an Underwriter pursuant to Section 7 will be mailed,
delivered or telegraphed and confirmed to such Underwriter.

     11.  Successors. This Agreement will inure to the benefit of and be binding
upon the parties hereto and their respective successors and the officers and
directors and controlling persons referred to in Section 7, and no other person
will have any right or obligation hereunder.

     12.  Representation of Underwriters.  The Representatives will act for the
several Underwriters in connection with this financing, and any action under
this Agreement taken by the Representatives jointly or by CSFBC will be binding
upon all the Underwriters.

     13.  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

     14.  Applicable Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York, without regard to principles
of conflicts of laws.

     The Company hereby submits to the non-exclusive jurisdiction of the Federal
and state courts in the Borough of Manhattan in The City of New York in any suit
or proceeding arising out of or relating to this Agreement or the transactions
contemplated hereby.

                                       19


  If the foregoing is in accordance with the Representatives' understanding of
our agreement, kindly sign and return to the Company one of the counterparts
hereof, whereupon it will become a binding agreement between the Company and the
several Underwriters in accordance with its terms.

                                     Very truly yours,

                                     INTERTRUST TECHNOLOGIES CORPORATION
