                                    RECITALS

A. Sublandlord and Moffett Park Drive LLC, a California limited liability

agreement dated September 11, 2000, a First Amendment to Lease dated January 12,
2001, and a Second Amendment to Lease dated October 31, 2002 (collectively,
"Master Lease").

B. Subtenant and Sublandlord entered into an Amended and Restated Sublease dated
June 28, 2001 ("Sublease"), under which Sublandlord sublets to Subtenant the
building described in the Master Lease as Building 1 and the third and fourth
floors of the building described in the Master Lease as Building 4 (the

"Furniture Agreement"); (ii) a Work Letter Agreement dated June 28, 2001; (iii)
a Consent to Sublease dated August 3, 2001 (the "Master Landlord's Consent");

(collectively, the "Cafeteria Agreement"); (v) a Fitness Center Access Agreement

connection with the Furniture Agreement, Subtenant has caused Wells Fargo Bank

and Subtenant amended and modified the Amended and Restated Sublease, terminated
the Furniture Agreement and took certain actions regarding the Building Four L/C
and Furniture L/C to Wells Fargo Bank. Sublandlord and Subtenant now desire to

F. Sublandlord and Subtenant now desire to amend and modify the Sublease, to
terminate the Furniture Agreement, and to take certain actions regarding the
Building Four L/C and Furniture L/C to Wells Fargo Bank, all as set forth in
this First Amendment.



                                    AGREEMENT

For and in consideration of the foregoing recitals and the respective
undertakings of the parties, and other good and valuable consideration, the
receipt and adequacy of which are acknowledged, Sublandlord and Subtenant hereby
agree as follows:

1. CAPITALIZED TERMS. Each capitalized term used in this First Amendment shall
have the meaning ascribed to it in the Sublease, unless such term is otherwise
defined in this First Amendment.

2. REDUCTION OF PREMISES. A portion of the Premises consists of the third and
fourth floors of Building 4 ("Reduction Space") Subtenant has not occupied the
Reduction Space. Sublandlord is currently negotiating a sublease with Motorola,
Inc. ("Motorola Sublease") for the Reduction Space. Effective as of the
commencement date of the Motorola Sublease ("Reduction Effective Date"), the
Reduction Space shall no longer be part of the Premises. As used in this First
Amendment, the "commencement date of the Motorola Sublease" shall be deemed to
occur on the first date that Motorola is allowed by Sublandlord to occupy the
Reduction Space under the Motorola Sublease for cabling, installation of
furniture, fixtures, or equipment, tenant improvement work, move-in, or any
other purpose.

As of the Reduction Effective Date, the Reduction Space shall be deemed
surrendered by Subtenant to Sublandlord, the Sublease shall be deemed terminated
with respect to the Reduction Space, and the Premises, as defined in the
Sublease, shall no longer include the Reduction Space. Notwithstanding the
foregoing, if Subtenant's representations contained in Paragraph 9(E) herein
shall be materially false or misleading, Sublandlord shall have the right to
declare this Amendment null and void and to reinstate the Sublease with respect
to the Reduction Space in addition to, and not in lieu of, any other rights or
remedies available to Sublandlord. In the event that the Reduction Effective
Date has not occurred by November 30, 2004, either party may terminate this
Amendment by written notice to the other party no later than December 15, 2004.

Notwithstanding anything in this First Amendment to the contrary, Subtenant
shall remain liable for all of its obligations as Subtenant under the Sublease
with respect to the Reduction Space arising prior to the Reduction Effective
Date, and Sublandlord shall remain liable for all of its obligations as
Sublandlord under the Sublease with respect to the Reduction Space arising prior
to the Reduction Effective Date.

3. BASE RENT. Subject to the express terms hereof, effective as of the Reduction
Effective Date, the schedule of Base Rent contained in paragraph 11 of the Basic
Sublease Information in the Sublease is deleted in its entirety, and the
following is substituted therefor:

Base Rent for the calendar month during which the Reduction Effective Date
occurs shall be prorated based on the actual number of days in that month.



4. OPTION TERM BASE RENT. In the event Subtenant validly exercises its option to
extend the term of the Sublease as provided in Section 39 of the Sublease, the
Base Rent for the Option Term shall be as follows:



Period                $/month/SF      SF        $/month

5. SUBTENANT'S SHARE. As a result of the reduction in the Premises, Subtenant's
Share shall be proportionately reduced. Section 12 of the Basic Sublease
Information is therefore deleted in its entirety, and the following is
substituted therefor:

"12. Subtenant's Share: 24.45% (total), comprised of: 6.00% (1st floor of
                                                      Building One)

Notwithstanding anything in this First Amendment to the contrary, Subtenant
shall remain liable for all year-end adjustments with respect to Subtenant's
Share applicable to the Reduction Space for that portion of the calendar year
preceding the Reduction Effective Date. Such adjustments shall be paid at a
time, in a manner and otherwise in accordance with the terms of the Sublease,
unless otherwise specified herein.

6. FURNITURE RENTAL AGREEMENT. Under the Furniture Agreement, Subtenant is
renting from Sublandlord certain furniture ("Furniture") located in the
Reduction Space. The parties hereby agree that effective as of the Reduction
Effective Date, the Furniture Agreement shall be terminated. Effective as of the
Reduction Effective Date, the security interest in the Furniture granted by
Sublandlord to Subtenant under the Furniture Agreement shall terminate and be of
no further force or effect. Subtenant hereby authorizes Sublandlord to file a
UCC Financing Statement Amendment, terminating Subtenant's security interest in
the Furniture ("UCC Termination Statement"), with the California Secretary of
State and the Santa Clara County Recorder, as appropriate, immediately following
the Reduction Effective Date. In the event this First Amendment is terminated
for any reason without the reduction in the Premises contemplated herein
becoming effective, Sublandlord agrees it shall not file or record the UCC
Termination Statement.

Within three (3) business days following Sublandlord's receipt of the
Termination Fee described below, Sublandlord shall return the original Furniture

by cashier's or certified check or by wire transfer of immediately available
funds to an account designated by Sublandlord within three (3) days following
the Reduction Effective Date.

8. AS IS ACCEPTANCE. Sublandlord acknowledges that Sublandlord has had an
opportunity to inspect the Reduction Space and the furniture covered by the
Furniture Agreement, and that both are in good condition and repair, free of
damage, loss or deterioration. Sublandlord therefore hereby accepts the same in
their present condition and configuration. Effective as of the date of this
First Amendment, and continuing until the earlier of (i) the Reduction Effective
Date and (ii) the date this First Amendment is terminated for any reason without
the reduction in the Premises contemplated herein becoming effective, Subtenant
shall have no access to and shall not use the Reduction Space or the Furniture.

9. SUBLEASE SECURITY DEPOSIT; BUILDING FOUR LETTER OF CREDIT. Effective as of
the Reduction Effective Date, the Security Deposit required under Paragraph 4 of
the Sublease shall be reduced to Six Million Six Hundred Thousand Dollars
($6,600,000), subject to further reduction during the term of the Sublease if
the financial milestones and other requirements of Paragraph 4 of the Sublease
are fully satisfied, however, that in no event shall the amount of the Security
Deposit be less than (i) $1,692,552.71 during the Original Term, and (ii)
$2,164,818.90 during the Option Period.

Within three (3) business days following Sublandlord's receipt of the

10. CAFETERIA AGREEMENT. The Cafeteria Agreement shall continue in full force
and effect after the Reduction Effective Date; provided, however, that effective
as of the Reduction Effective Date, Section 1.a. of Exhibit C shall no longer
apply, and Sections 1.b. and 1.c. of Exhibit C shall be amended in their
entirety to read as follows:

      "b. 3rd Party Monthly Operating Loss and Profit Sharing:

      Interwoven shall be responsible for and shall pay to Ariba fifty percent
      (50%) of any and all monthly operating loss sustained by the Cafeteria
      Operator during the Term after any such monthly operating loss is first
      reduced by the amount of such loss payable by other subtenants of the
      Project.

      Interwoven shall receive from Ariba fifty percent (50%) of any and all
      monthly operating profit earned by the Cafeteria Operator during the Term
      after any such monthly operating profit is first reduced by the amount of
      such profit payable to other subtenants of the Project.

      c. Operating Expenses:

      Interwoven shall be responsible for and shall pay to Ariba a monthly fee
      in an amount equal to the "Subtenant's Share" or twenty-four and

      Cafeteria."

Following the Reduction Effective Date, Subtenant's Share shall be determined in
accordance with Section 5 of this First Amendment.

11. RATIFICATION OF SUBLEASE AND RELATED AGREEMENTS. Subject to the express
recitals and provisions of this First Amendment, Subtenant and Sublandlord
acknowledge and agree that the Sublease and the Related Documents are in full
force and effect (as they relate to the portion of the Premises remaining after
deletion of the Reduction Space), and have not been amended, modified, or
assigned, either orally or in writing. Subtenant represents and warrants to
Sublandlord that Subtenant has no present claim, offset or defense under the
Sublease or the Related
