interest; (g) to file, in its sole discretion, one or more financing or
continuation statements and amendments thereto, relative to any of the

                                   ---------

                    INTELLECTUAL PROPERTY SECURITY AGREEMENT

     This Intellectual Property Security Agreement is entered into as of October
28, 1998, by and between SILICON VALLEY BANK ("Bank") and CROSSWORLDS SOFTWARE,
INC. ("Grantor").

                                   RECITALS
                                   --------

     A.   Bank has agreed to make certain advances of money and to extend
certain financial accommodation to Grantor (the "Loans") in the amounts and
manner set forth in that certain Loan and Security Agreement dated as of
December 10, 1996, as amended from time to time, including, without limitation,
the First Amendment to Loan and Security Agreement, dated as of September 29,
1997, and the Second Amendment to Loan and Security Agreement, dated as of
October 28, 1998 (as the same may be amended, modified or supplemented from time
to time, the "Loan Agreement"; capitalized terms used herein are used as defined
in the Loan Agreement). Bank is willing to make the Loans to Grantor, but only
upon the condition, among others, that Grantor shall grant to Bank a security
interest in certain Copyrights, Trademarks and Patents to secure the obligations
of Grantor under the Loan Agreement.

     B.   Pursuant to the terms of the Loan Agreement, Grantor has granted to
Bank a security interest in all of Grantor's right, title and interest, whether
presently existing or hereafter acquired, in, to and under all of the
Collateral.

     NOW, THEREFORE, for good and valuable consideration, receipt of which is
hereby acknowledged, and intending to be legally bound, as collateral security
for the prompt and complete payment when due of its obligations under the Loan
Agreement, Grantor hereby represents, warrants, covenants and agrees as follows:

                                   AGREEMENT
                                   ---------

     To secure its obligations under the Loan Agreement, Grantor grants and
pledges to Bank a security interest in all of Grantor's right, title and
interest in, to and under its Intellectual Property Collateral (including
without limitation those Copyrights, Patents and Trademarks listed on Schedules
A, B and C hereto), and including without limitation all proceeds thereof (such
as, by way of example but not by way of limitation, license royalties and
proceeds of infringement suits), the right to sue for past, present and future
infringements, all rights corresponding thereto throughout the world and all re-
issues, divisions continuations, renewals, extensions and continuations-in-part
thereof.

     This security interest is granted in conjunction with the security interest
granted to Bank under the Loan Agreement. The rights and remedies of Bank with
respect to the security interest granted hereby are in addition to those set
forth in the Loan Agreement and the other Loan Documents, and those which are
now or hereafter available to Bank as a matter of law or equity. Each right,
power and remedy of Bank provided for herein or in the Loan Agreement or any of
the Loan Documents, or now or hereafter existing at law or in equity shall be
cumulative and concurrent and shall be in addition to every right, power or
remedy provided for herein and the exercise by Bank of any one or more of the
rights, powers or remedies provided for in this Intellectual Property Security
Agreement, the Loan Agreement or any of the other Loan Documents, or now or
hereafter existing at law or in equity, shall not preclude the simultaneous or
later exercise by any person, including Bank, of any or all other rights, powers
or remedies.

     Notwithstanding the foregoing, the filing on the Patents, Copyrights and
Trademarks described on Schedules A, B and C hereto, is solely for the purpose
of perfecting a security interest in the accounts receivable with respect to
such Intellectual Property Collateral.

     Notwithstanding the foregoing, the term "Intellectual Property Collateral"
shall not include any general intangibles or contracts of Borrower (whether
owned or held as licensee or lessee, or otherwise) to the extent that (i) such
general intangibles are not assignable or capable of being encumbered as a
matter of law or under the terms of the license, lease or other agreement
applicable thereto (but solely to the extent that such restriction shall be
enforceable under applicable law) without the consent of the licensor or

                                       1
<PAGE>

lessor thereof or other applicable party thereto and (ii) such consent has not
been obtained; provided, however, that the foregoing grant of security interest
               --------  -------
shall extend to, and the term "Intellectual Property Collateral" shall include,
(A) any general intangible which is an Account or a proceed of, or otherwise
related to the enforcement or collection of, any Account or goods which are the
subject of any Account, and (B) any and all proceeds of any general intangibles
which are otherwise excluded to the extent that the assignment or encumbrance of
such proceeds is not so restricted, and (C) upon obtaining the consent of any
such licensor, lessor or other applicable party with respect to any such
otherwise excluded general intangibles, such general intangibles as well as any
and all proceeds thereof that might theretofore have been excluded from such
grant of a security interest and the term "Intellectual Property Collateral".

     IN WITNESS WHEREOF, the parties have cause this Intellectual Property
Security Agreement to be duly executed by its officers thereunto duly authorized
as of the first date written above.

                          LOAN MODIFICATION AGREEMENT

     This Loan Modification Agreement is entered into as of September 21, 1999,
by and between Crossworlds Software, Inc. ("Borrower") and Silicon Valley Bank
("Bank").

1.   DESCRIPTION OF EXISTING INDEBTEDNESS:  Among other indebtedness which may
     ------------------------------------
be owing by Borrower to Bank, Borrower is indebted to Bank pursuant to, among
other documents, a Loan and Security Agreement, dated December 10, 1996, as may
be amended from time to time, (the "Loan Agreement"). The Loan Agreement
provided for, among other things, a Revolving Committed Line in the original
principal amount of One Million Five Hundred Thousand Dollars ($1,500,000). The
Loan Agreement was amended pursuant to, among other documents, a Second
Amendment to Loan and Security Agreement, dated October 28, 1998 pursuant to
which, among other things, the Revolving Committed Line was amended to Ten
Million Dollars ($10,000,000). Defined terms used but not otherwise defined
herein shall have the same meanings as in the Loan Agreement.

Hereinafter, all indebtedness owing by Borrower to Bank shall be referred to as
the "Indebtedness."

2.   DESCRIPTION OF COLLATERAL AND GUARANTIES.  Repayment of the Indebtedness is
     ----------------------------------------
secured by the Collateral as described in the Loan Agreement and in that certain
Intellectual Property Security Agreement, dated October 28, 1998, by and between
Borrower and Bank.

Hereinafter, the above-described security documents and guaranties, together
with all other documents securing repayment of the Indebtedness shall be
referred to as the "Security Documents". Hereinafter, the Security Documents,
together with all other documents evidencing or securing the Indebtedness shall
be referred to as the "Existing Loan Documents".

3.   DESCRIPTION OF CHANGE IN TERMS.
     ------------------------------

     A.   Modification(s) to Loan Agreement.
          ----------------------------------

          1.   The term "Borrowing Base" as defined in Section 2.1.3 entitled
               "Revolving Facility" is hereby amended to read as follows:

               For purposes of this Agreement, "Borrowing Base" shall mean an
               amount equal to sixty percent (60%) of Eligible Accounts.

          2.   Notwithstanding the terms and conditions contained in item "(1)"
               under Section 2.2(a) entitled "Interest Rate", effective as of
               August 9, 1999, all Revolving Advances shall bear interest, on
               the average Daily Balance thereof, at a rate equal to one and
               one-tenth percentage point (1.10) above the Prime Rate, until
               such time as Bank receives evidence that Borrower is in receipt
               of new equity in an amount not less than $12,000,000 at which
               time all Revolving Advances shall bear interest, on the average
               Daily Balance thereof, at a rate equal to one-tenth of one
               percentage point (0.10) above the Prime Rate, beginning the first
               day of the month following Bank's receipt of such evidence of
               Borrower's receipt of new equity.

          3.   Effective as of month ending August 31, 1999, the financial
               covenants under Section 6.8 entitled "Quick Ratio" and Section
               6.10 entitled "Tangible Net Worth" shall be measured as of the
               last day of each month (rather than each fiscal quarter).

4.   CONSISTENT CHANGES.  The Existing Loan Documents are hereby amended
     ------------------
wherever necessary to reflect the changes described above.
<PAGE>

5.   NO DEFENSES OF BORROWER.  Borrower (and each guarantor and pledgor signing
     -----------------------
below) agrees that, as of the date hereof, it has no defenses against the
obligations to pay any amounts under the Indebtedness.

6.   CONTINUING VALIDITY.  Borrower (and each guarantor and pledgor signing
     -------------------
below) understands and agrees that in modifying the existing Indebtedness, Bank
is relying upon Borrower's representations, warranties, and agreements, as set
forth in the Existing Loan Documents. Except as expressly modified pursuant to
this Loan Modification Agreement, the terms of the Existing Loan Documents
remain unchanged and in full force and effect. Bank's agreement to modifications
to the existing Indebtedness pursuant to this Loan Modification Agreement in no
way shall obligate Bank to make any future modifications to the Indebtedness.
Nothing in this Loan Modification Agreement shall constitute a satisfaction of
the Indebtedness. It is the intention of Bank and Borrower to retain as liable
parties all makers and endorsers of Existing Loan Documents, unless the party is
expressly released by Bank in writing. No maker, endorser, or guarantor will be
released by virtue of this Loan Modification Agreement. The terms of this
paragraph apply not only to this Loan Modification Agreement, but also to all
subsequent loan modification agreements.

     This Loan Modification Agreement is executed as of the date first written
above.
