         accordance with the requirements and specifications set forth in the

         applicable requirements, specifications, schedules, outputs, and other
         services associated with the Deliverables and the Services. The parties
         also intend to discuss certain additional work efforts in the future

         Statements of Work. Although the parties agree to consider additional
         work efforts, there is no assurance that additional Statements of Work
         will be authorized or agreed upon.

2.2      Requested Changes.

                  will supply a Change Request to ChiLin. A Change Request must

                  Vitria supplies a Change Request, at ChiLin's cost, ChiLin
                  shall conduct an analysis of the impact of the request on the
                  price, schedule, Deliverables and/or Services of the relevant
                  Statement of Work and submit a written summary to Vitria for
                  approval. ChiLin reserves the right, for a significant work
                  effort associated in an impact analysis for a change request,
                  to charge Vitria on a time and materials basis, using the time
                  and materials services rates specified in the Statement of
                  Work to which the Change Request applies, or as otherwise
                  mutually agreed by Vitria and ChiLin. Any impact analysis work
                  to be charged to Vitria shall require prior approval from
                  Vitria; such approval shall not be unreasonably withheld. The
                  authority to authorize any impact analysis work must come, in
                  writing, from Vitria's VP of Customer Services and Engineering
                  Operations (or other designated executive officer), otherwise,
                  no such charges will be honored.

         2.2.2    Once the impact analysis of a Change Request has been
                  completed, it shall be submitted in writing to Vitria
                  management for approval. Change Requests shall only be acted
                  upon once they have been agreed and duly authorized in writing
                  by both ChiLin and Vitria. Neither party will have any
                  obligation to execute a Change Request.

2.3      The parties will discuss progress made on the Deliverables and issues
         that may arise with respect to the Services during the status meetings
         as required under a Statement of Work. Either party will notify the

         Deliverables or the Services.

                  otherwise infringe Vitria's intellectual property rights when
                  disclosed by ChiLin, (ii) was in the rightful possession of

                  of this Agreement, (iii) is disclosed as a matter of right by
                  a third party after the execution of this Agreement.

         10.1.2   ChiLin warrants that all employees, independent contractors
                  and consultants of ChiLin having access to any Vitria
                  Confidential Information, or who may reasonably be anticipated
                  to be exposed to any Vitria Confidential Information, have
                  entered into, or will enter into prior to providing Services,
                  a confidentiality agreement which contains, at a minimum, the
                  substance of the preceding paragraph, as well as an
                  acknowledgment providing coverage that (a) Vitria owns the
                  Vitria Products, the Deliverables, the Vitria Modifications
                  and the Vitria Materials, and (b) they assign all their rights

                  created. At the request of Vitria, ChiLin shall provide copies
                  of such agreements to Vitria.

         10.1.3   In the event of a breach of this Section 10.1, money damages
                  will not be an adequate remedy, and therefore, in addition to
                  any other legal or equitable remedies, Vitria shall be
                  entitled to seek an injunction or other equitable relief
                  against such breach without necessity of posting bond or

                  independent contractors and consultants shall use the same
                  degree of care as Vitria uses to protect its own confidential
                  information of a similar nature, but in no event less than
                  reasonable care, to avoid disclosure of ChiLin Confidential
                  Information. The foregoing obligation of nondisclosure shall
                  not apply to information which: (i) was already publicly known
                  or was independently developed when disclosed by ChiLin, (ii)
                  was in the rightful possession of Vitria at the time of

                  minimum, the substance of the preceding paragraph. At the
                  request of ChiLin, Vitria shall provide copies of such
                  agreements to ChiLin.

         10.2.3   In the event of a breach of this Section 10.2, money damages
                  will not be an adequate remedy, and therefore, in addition to
                  any other legal or equitable remedies, ChiLin shall be
                  entitled to seek an

                                                                    Page 8 of 15

         worked up to the point of termination with respect to each Statement of
         Work, Notwithstanding anything to the contrary in the preceding
         sentence, the amounts due from Vitria to ChiLin for early termination
         of a Statement of Work whose costs are based solely on a time and
         materials basis shall be calculated as the actual time and material
         expended as of the date of such termination. No Acceptance Testing will
         be required beyond the date of the written notice of termination.

13.3     Without prejudice to any rights either party may have under this
         Agreement or in law, equity or otherwise, either party shall have the
         right to terminate this Agreement if the other party defaults in the
         performance of any of its obligations or breaches any term, provision,
         warranty, or representation under this Agreement and fails to correct
         the Default or to commence any and all steps reasonably necessary to
         cure such Default within thirty (30) days of receipt of written notice
         of such default by the non-defaulting party.

13.4     Should either party become the subject of any proceeding under
         provincial, state or federal law for due relief of debtors or otherwise
         become insolvent or bankrupt or make an assignment for the benefit of
         creditors, the other party may, in addition to any other right or
         remedy it may have, terminate this Agreement without liability to the
         non-defaulting party upon written notice; provided, however, that
         neither party shall be deemed in default for delays due to causes
         beyond its reasonable control.

13.5     Upon termination of this Agreement, ChiLin shall thereafter cease to
         use (i) any Vitria software provided under this Agreement and (ii) any
         copies of the Deliverables, and shall delete such Deliverables and
         Vitria software from its library, and shall return to Vitria or destroy
         all copies of such Deliverables, and shall notify Vitria in writing
         that this has been done; provided, however, that notwithstanding the
         foregoing, ChiLin shall be entitled to retain a single copy of the
         Deliverables and Vitria software for archival, maintenance and support
         purposes, and not for enhancement or development.

13.6     The provisions of Sections 9 (Ownership), 10 (Nondisclosure), 11
         (Warranty/Indemnification), 12 (Limitation of Liability), 13 (Term and
         Termination) and 14 (Miscellaneous) shall survive termination of this
         Agreement.

         incorporated into this Agreement. This Agreement may be executed in any
         number of counterparts and/or duplicate originals.

                                                                   Page 12 of 15

14.2     Assignment. ChiLin may not assign this Agreement without the prior
         written consent of Vitria. Any purported assignment in contravention of
         this section is null and void. A transfer of a controlling interest in
         the equity of ChiLin shall be deemed an assignment for purposes of this
         subsection. Subject to the foregoing, this Agreement will bind and
         inure to the benefit of any successors or assigns.

14.3     Attorneys' Fees. The prevailing party in any suit under this Agreement
         shall recover all costs, expenses and reasonable attorney fees incurred
         in such action.

14.4     Controversies. Before either party commences any action against the
         other party, it shall give written notice to the other party of its
         intention to file a claim, and the senior management of the parties
         then shall meet in good faith to resolve the dispute.

14.5     Definitions and Section Headings. Singular terms shall be construed as
         plural, and vice versa, where the context requires. Section headings
         are a matter of convenience and shall not be considered part of this
         Agreement.

14.6     Entire Agreement. This Agreement is the complete and exclusive
         statement of the understandings of the parties, and it supersedes and
         merges all prior proposals and understandings, whether oral or written,
         relating to the subject matter of this Agreement. This Agreement may
         not be modified except in writing, signed by an officer of Vitria and a
         duly authorized representative of ChiLin, and expressly referring to
         this Agreement. This Agreement takes precedence over any purchase order
         issued by either party, which may accepted by the other party for
         administrative convenience only.

14.7     Export. The parties shall comply with the Export Laws. Neither party
         will export or re-export directly or indirectly (including via remote
         access) any part of the Deliverables, Vitria Owned Technology, Vitria
         Owned Modifications, ChiLin Technology, ChiLin Owned Modifications or
         any Confidential Information to any country for which a validated
         license is required under the Export Laws without first obtaining a
         validated license.

14.8     Force Majeure. Neither party will be responsible for failure of
         performance, other than for an obligation to pay money, due to causes
         beyond its control, including, without limitation, acts of God or
         nature; labor disputes; sovereign acts of any federal, state or foreign
         government; or shortage of materials.

14.9     Governing Law. This Agreement shall be governed by and construed in
         accordance with the laws of the State of California, but without giving
         any effect to the choice of law principles thereunder.

14.10    Independent Contractors; Nonexclusive. Vitria and ChiLin are
         independent contractors and will so represent themselves in all
         regards. Neither party may bind the other in any way. Nothing in this
         Agreement will be construed to make either party the agent or legal
         representative of the other or to make the parties partners or joint
         venturers.

14.11    Notices. All notices, consents and approvals under this Agreement must
         be delivered in writing by courier, or by certified or registered mail
         (postage prepaid and return receipt requested), to the other party at
         the address set forth beneath such party's signature, and will be
         effective upon receipt or three (3) business days after being deposited
         in the mail as required above, whichever occurs sooner. Either party
         may change its address by giving notice of the new address to the other
         party.

                                                                   Page 13 of 15

14.12    Severability. If any provision of this Agreement is found by a court of
         competent jurisdiction to be invalid or unenforceable, the remainder of
         the Agreement shall continue in full force and effect. However, should
         either party reasonably conclude that a provision held to be invalid or
         unenforceable was a material inducement to its entering into this
         Agreement, and the loss of that provision has deprived it of the
         benefit of the bargain reached upon execution of this Agreement, then
         that party may, upon 10 days prior written notice, terminate this
         Agreement.

14.13    Waiver. The waiver of one breach or default shall not constitute the
         waiver of any subsequent breach or default, and shall not act to amend
         or negate the rights of any party.

                                                                   Page 14 of 15

DELIVERED VIA E-MAIL

December 10, 2003

Mr. James Guthrie
Vitria Technologies, Inc.
945 Stewart Street
Sunnyvale, CA 94085

Dear Jim:

We are delighted to offer you the position of Senior Vice President, Engineering
at Vitria Technology, Inc. (the "Company", "Vitria") reporting to the Chief
Executive Officer (CEO). Your anticipated start date is Monday, January 5, 2004.

Your annual base salary will be $275,000. You will be paid bi-monthly at a rate
of $11,458.34 payable on the 15th and 30th/31st of each month. In addition, you
will be eligible for an (annualized) target bonus at 50% of your base salary.
The target bonus will be paid annually based upon the 2004 Executive
Compensation Plan to be approved by the Compensation Committee.

Annual Base Salary:    $275,000
Annual Bonus Target:   $137,500

50% of your 2004 target bonus will be guaranteed in the amount of $68,750.00.
The remaining 50% of your target bonus will be based on the 2004 Executive Bonus
Plan to be approved by the Compensation Committee. You will receive a sign-on
bonus of $75,000 less statutory withholdings provided you start on or before
January 5, 2004. You agree that this amount will be repaid to Vitria in full, if
you resign or are terminated for "cause" within the first 12 months of your
employment with Vitria. The sign-on bonus will be paid on the January 30th, 2004
payroll.

If your employment with the Vitria is terminated by the Company "Without Cause"
or if you resign, "With Good Reason" not in connection with a "Change of
Control", you shall be entitled to receive a one time lump sum payment equal to
twelve (12) months of Base Salary (subject to applicable tax withholding)
following the termination date.

DEFINED TERMS:

Cause

         (a) theft; a material act of dishonesty or fraud; intentional
falsification of any employment or Company records; or the commission of any
criminal act which impairs your ability to perform appropriate employment duties
for the Company;

         (b) improper disclosure or use of the Company's confidential, business
or proprietary information;

         (c) conviction (including any plea of guilty or nolo contendere) for a
crime involving moral turpitude causing material harm to the reputation and
standing of the Company, as determined by the Company in its sole discretion;

         (d) gross negligence or willful misconduct in the performance of your
assigned duties; or

<PAGE>

         (e) repeated failure to perform job responsibilities in accordance with
written instructions from the CEO.

Without Cause. For all purposes under this Agreement, a termination of the
employment by the Company "Without Cause" shall mean a termination by the
Company in the absence of "Cause", as defined above, but in no event shall the
term "Without Cause" include a termination as a result of death or disability.

With Good Reason. For all purposes under this Agreement, "With Good Reason" for
resignation will exist if you resign from employment within 60 days after the
occurrence, without your written consent, of any of the following: (i) any
material reduction in your Base Salary or Target Bonus; (ii) any material
reduction in your benefits; (iii) a change in your position with the Company or
a successor company that materially reduces your stature (see attached Job
Description); or (iv) a material breach by the Company of its obligations under
this Agreement, that is not corrected within thirty (30) days following written
notice thereof to the Company by you, such notice to state with specificity the
nature of the failure; provided that if such failure cannot reasonably be
corrected within thirty (30) days of written notice thereof, correction shall be
commenced by the Company within such period and may be corrected within a
reasonable period thereafter.

Vitria will recommend to the Compensation Committee of the Board of Directors
that you be granted under its Equity Incentive Plan, an option to purchase
275,000 shares of Common Stock (the "Option"), at an exercise price equal to the
fair market value established by the Compensation Committee on the date of grant
which shall be as soon as reasonably practicable following your start date. Such
Option shares shall vest 25% after twelve months of continuous service with the
remaining amount vesting, in equal installments at the end of each calendar
month, over the following thirty-six months.

It is agreed by both parties that you will be covered by the terms of the
company's Board-approved Change of Control agreement for executives of the
Company as approved and adopted by the Board of Directors. See the attached "Key
Employee Retention and Severance Plan" adopted January 22, 2002.

As a Vitria employee, you will be expected to abide by Vitria's policies and
procedures, and sign and comply with the Proprietary Information and Inventions
Agreement. Your employment at Vitria Technology is at will, that is, not for a
specified term. This means that either you or Vitria may terminate your
employment at any time for any reason, with or without cause or advance notice.

All new employees must pass an employment verification procedure before they are
permitted to work. This procedure has been established by Vitria and requires
every individual to provide satisfactory evidence of his/her identity and legal
authority to work in the United States within twenty-four (24) hours of his/her
start date. Upon acceptance of this offer, we will forward you an Employment
Eligibility Verification Form indicating the types of acceptable documentation.
Please bring the appropriate document(s) with you on your first day of work.

<PAGE>

This letter, the Proprietary Information and Inventions Agreement, and the Key
Employee Retention and Severance Plan, constitute the entire and final agreement
between you and Vitria regarding your employment and supersede any other
agreements, representations or promises. You understand that this agreement
cannot be changed or amended except in writing signed by you and by an
authorized company representative.

We are looking forward to having you join the team. Please sign below to
indicate your acceptance of this offer. This offer expires Friday, December 12,
2003.

Sincerely yours,

   /s/ Gary S. Velasquez
