                  6.    Section 6.6 of the Loan Agreement is hereby amended and
restated in its entirety to read as follows:

                  6.6   Deposit and Investment Accounts.

            Borrower will maintain its primary depository and operating accounts
      with Bank and all of its investment accounts with SVB Asset Management,
      which investment accounts are hereby pledged to Bank to secure the
      Obligations (and shall be subject to a control agreement in form and
      substance satisfactory to Bank).

                  7.    Section 6.10 of the Loan Agreement is hereby amended and
restated in its entirety to read as follows:

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.

      8.    CONDITIONS. The effectiveness of this Loan Modification Agreement is
conditioned upon the receipt by Bank of a fully executed copy of this Loan
Modification Agreement.

                                       2.

Dear Jeff:

This letter sets forth the substance of the separation agreement (the
"Agreement") that Vitria Technology, Inc. (the "Company") is offering to you to
aid in your employment transition.

      1.    SEPARATION DATE AND TRANSITION PERIOD. Your last day of employment
with the Company will be June 30, 2004, (the "Separation Date"). During the
period beginning on the date this Agreement becomes effective until the
Separation Date (the "Transition Period"), you will continue to serve as the
Chief Financial Officer of the Company. You will continue to devote your full
work efforts to the Company and will exercise your best professional efforts to
perform your current duties and to transition your duties to a new Chief
Financial Officer. During the Transition Period, you will receive your current
salary and benefits, your unvested stock options will continue to vest, and all
other terms and conditions of your employment will apply (including your
obligation to abide by Vitria's policies and procedures).

      2.    ACCRUED SALARY AND PAID TIME OFF. On the Separation Date, the
Company will pay you all accrued salary, and all accrued and unused vacation
earned through the Separation Date, subject to standard payroll deductions and
withholdings. You are entitled to these payments by law.

      3.    SEVERANCE PAYMENTS. Although the Company has no obligation to do so,
if you sign this Agreement and allow it to become effective, and if on the
Separation Date you sign the Separation Date Release attached hereto as Exhibit
A and allow it to become effective, then within ten (10) business days after the
Separation Date, the Company will pay you, as severance, the equivalent of
twelve (12) months of your current base salary payable in equal monthly
installments over a twelve (12) month period, subject to standard payroll
deductions and withholdings.

      4.    HEALTH INSURANCE. To the extent provided by federal COBRA law and
the Company's current group health insurance policies, you are eligible to
continue your current health insurance benefits at your own expense. Later, you
may be able to convert to an individual policy through the provider of the
Company's health insurance. If you timely elect coverage under

                                                                  April 27, 2004

COBRA and comply with all of your obligations under this Agreement, then the
Company will pay the premiums necessary to continue your current health
insurance benefits for twelve (12) months following the Separation Date.

      5.    STOCK OPTIONS. Your stock options will be treated as follows.

            a.    93,750 OPTIONS GRANTED ON MARCH 3, 2003. You were granted
93,750 stock options on March 3, 2003. Vesting of your stock options from this
grant will cease as of the Separation Date, at which time you will have vested
in 23,437 options from this grant. As further consideration for this Agreement,
the Company will accelerate the vesting of the remaining 70,313 unvested options
from this grant such that the total amount of 93,750 options shall be deemed
vested as of the Separation Date. Except as modified herein, your right to
exercise any vested shares, and all other rights and obligations with respect to
these options, will be as set forth in your stock option agreement(s), grant
notice(s) and applicable plan documents.

            b.    50,000 OPTIONS GRANTED ON AUGUST 26, 2003. You were granted
50,000 stock options on August 26, 2003. Vesting of your stock options from this
grant will cease as of the Effective Date of this Agreement (as defined in
Paragraph 14 herein). You further agree as part of this Agreement to waive any
and all rights you may have to exercise any vested options from this grant, and
agree not to attempt to exercise any of these options from the date you sign
this Agreement until the Effective Date. Except as modified in this Paragraph
5(b), all other rights and obligations with respect to these options will be as
set forth in your stock option agreement(s), grant notice(s) and applicable plan
documents.

            c.    156,250 OPTIONS GRANTED ON AUGUST 26, 2003. You were granted

5(c), all other rights and obligations with respect to these options will be as
set forth in your stock option agreement(s), grant notice(s) and applicable plan
documents.

      6.    OTHER COMPENSATION OR BENEFITS. You acknowledge that, except as
expressly provided in this Agreement, you will not receive any additional
compensation, severance or benefits after the Separation Date, with the sole
exception of any benefit the right to which has vested under the express terms
of a Company benefit plan document.

      7.    EXPENSE REIMBURSEMENTS. You agree that, within thirty (30) days of
the Separation Date, you will submit a documented expense reimbursement
statement reflecting all business expenses you incurred through the Separation
Date, if any, for which you seek reimbursement. The Company will reimburse you
for these expenses pursuant to its regular business practice.

and officers) agree not to disparage the other party, and the other party's
officers, directors, employees, shareholders and agents, in any manner likely to
be harmful to them or their business, business reputation or personal
reputation; provided that both you and the Company may respond accurately and
fully to any question, inquiry or request for information when required by legal
process. You also agree that you will not voluntarily assist any person in
bringing or pursuing legal action against the Company, its agents, successors,
representatives, employees and related and/or affiliated companies based on

      12.   RELEASE. In exchange for the severance benefits set forth in

federal, state, and local statutory claims, including claims for discrimination,
harassment, retaliation, attorneys' fees, or other claims arising under the
federal Civil Rights Act of 1964 (as amended), the federal Americans with
Disabilities Act of 1990, the federal Age Discrimination in Employment Act of
1967 (as amended) ("ADEA"), the California Fair Employment and Housing Act, and
the California Labor Code.

      13.   WAIVER OF UNKNOWN CLAIMS. In giving this release, which includes
claims that may be unknown to you at present, you acknowledge that you have read
and understand Section 1542 of the California Civil Code which reads as follows:
"A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR
SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF
KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR." You
expressly waive and relinquish all rights and benefits under that section and
any law of any jurisdiction of similar effect with respect to your release of
claims herein.

      14.   ADEA WAIVER. You hereby acknowledge that you are knowingly and
voluntarily waiving and releasing any rights you may have under the ADEA, and
that the consideration given for the foregoing waiver is in addition to anything
of value to which you were already entitled. You have been advised by this
writing, as required by the ADEA that: (a) your waiver and release do not apply
to any claims that may arise after your signing of this Agreement; (b) you
should consult with an attorney prior to executing this release; (c) you have
twenty-one (21) days within which to consider this release (although you may

between you and the Company with regard to this subject matter. It is entered
into without reliance on any promise or representation, written or oral, other
than those expressly contained herein, and it supersedes any other such promises
or representations. This Agreement may not be modified or amended except in a
writing signed by both you and a duly authorized officer of the Company. This
Agreement will bind the heirs, personal representatives, successors and assigns
of both you and the Company, and inure to the benefit of both you and the
Company, their heirs, successors and assigns. The failure to enforce any breach
of this Agreement shall not be deemed to be a waiver of any other or subsequent
breach. For purposes of construing this Agreement, any ambiguities shall not be
construed against either party as the drafter. If any provision of this
Agreement is determined to be invalid or unenforceable, in whole or in part,
this determination will not affect any other provision of this Agreement and the
provision in question will be modified by the court so as to be rendered
enforceable in a manner consistent with the intent of the parties insofar as
possible. This Agreement will be deemed to have been entered into and will be
construed and enforced in accordance with the laws of the State of California as
applied to contracts made and to be performed entirely within California. This
Agreement may be executed in counterparts which shall be deemed to be part of
one original, and facsimile signatures shall be equivalent to original
signatures.

If this Agreement is acceptable to you, please sign below and return the
original to me.
