January 8th 2004

Mr. Paul Albright

Dear Paul:

I am pleased to offer you, subject to Informatica Board approval, the position
of Executive Vice President and Chief Marketing Officer with Informatica
Corporation. In this capacity you will report to Gaurav Dhillon, CEO, and work
to help Informatica be successful in powering business insight for global
organizations.

The components of your package include:

An annual base salary of $250,000.
Annual bonus of $125,000 based on the terms of the executive bonus program
(which pays out against achievement of corporate financial targets). Annual
commission of $25,000 based on achievement of global bookings targets (to be set
each fiscal year).

Your annualized on target earnings are $400,000.

In addition, you will be granted 425,000 new hire stock options, subject to
approval by the Board of Directors. The option price will be the closing market
price of the stock on the first day of employment with Informatica. In the event
that your first day of employment occurs on a day that the markets are closed,
your option price will be the closing market price of the stock on the first
trading day following your start date. Vesting begins as of your hire date and
continues over a four-year period.

In the event that there is a change in control where Informatica is not the
surviving entity and where (i) a substantially similar position is not available
or is not offered to you, (ii) there is a material adverse change in your
position, causing such position to be of significantly less stature or of
significantly less responsibility, (iii) there is a reduction of more than ten
percent (10%) of your base compensation, unless in connection with similar
decreases of other similarly situated executives of the Company, or (iv) you are
asked and refuse to relocate to a facility or location more than fifty (50)
miles from the Company's current location, and you cease to be an employee, you
will be eligible for a severance package and acceleration of stock option
vesting, as detailed below:

         If such change of control and termination of your employment occurs
     within the first six months of your employment with Informatica, you will
     receive a lump-sum payment equal to your gross base salary for the period
<PAGE>

     beginning on your termination date and ending on the date that would have
     marked your first anniversary with Informatica. . In addition, for that
     same period, all of your outstanding Informatica employee stock options
     shall, on the date of your termination, have their vesting accelerated. For
     example, if any triggering event shall occur in month three (3) of your
     employment with Informatica, you will receive a lump-sum payment equal to
     nine (9) months' gross salary (less applicable withholdings) and the
     vesting on your outstanding stock options shall accelerate as to nine (9)
     months additional vesting.

         If such change of control and termination of your employment occurs
     after the first six months of your employment, you will receive a lump-sum
     payment equal to your gross base salary for a period equal to six (6)
     months as well as accelerated vesting of your outstanding employee stock
     options for a six (6) month period.

"Change of Control" shall mean the consummation of one of the following:

(i) the acquisition of a majority of the outstanding voting stock of the Company
by any third party who is not an affiliate of the Company pursuant to a tender
offer validly made under any federal or state law (other than a tender offer by
the Company).

(ii) a merger, consolidation or other reorganization of the Company (other than
a reincorporation of the Company), if after giving effect to such merger,
consolidation or other reorganization of the Company, the shareholders of the
Company immediately prior to such merger, consolidation or other reorganization
do not represent a majority in interest of the holders of voting securities (on
a fully diluted basis) with the ordinary voting power to elect directors of the
surviving entity after such merger, consolidation or other reorganization or

(iii) the sale of all or substantially all of the assets of the Company to a
third party who is not an affiliate of the Company.

You will also be eligible for standard company benefits. These benefits will be
available to you on your date of hire and include medical, dental and life as
well as eligibility to participate in the Company's 401(k) and Employee Stock
Purchase plans. Additionally, as an executive officer and Section 16 officer of
Informatica, you will be covered under the company's director and officer
liability insurance policy.

Your start date will be January 31 2004, or sooner.

After reading this letter and the enclosed Informatica Proprietary Agreement,
please indicate your acceptance of these employment terms by signing both
documents. Please

<PAGE>

return this letter and the agreement to our office. The offer and the agreement
enclosed herewith are valid through January 9th 2004 after which time this offer
shall lapse.

California is an employment at will state. As such, your employment is at the
mutual consent of both you and the Company and you are free to resign at any
time, just as Informatica is free to terminate your employment at any time, with
or without cause and with or without notice.

This offer is contingent upon your ability to provide identification as proof of
your right to work in the United States. We are required by law to view your
identification and complete the appropriate documentation for our records. It is
mandatory for you to present this identification within 3 working days of your
hire date. Failure to do so can result in a delay in your ability to begin work.

Please contact the Benefits Department on your first day of employment to
schedule a benefits orientation. (650-385-5209 or 650-385-5535)

Please confirm your agreed upon hire date by indicating it here: 1/16/04

Please mail the acceptance letter in the enclosed envelope to Informatica,
attention: Employment Department, 2100 Seaport Boulevard, Redwood City CA 94063
or you can fax a copy to 650-385-4131.

I look forward to working with you in the future and, on behalf of the Company
and its employees, extend a warm welcome to you.

Sincerely,

/s/ Earl Fry for Gaurav Dhillon

December 27, 2003

JoMei Chang
Vitria Technologies, Inc.
945 Stewart Street
Sunnyvale, CA 94085

Dear JoMei:

We appreciate your long service as a founder, executive, and employee of Vitria
Technology, Inc. (the "Company"). This letter sets forth the substance of the
separation agreement (the "Agreement") that the Company is offering to you.

         1.       RESIGNATION. You hereby resign, and the Company hereby accepts
your resignation, from any and all employment positions that you currently hold
with the Company, effective as of December 31, 2003 (the "Separation Date").

         2.       CHAIRMAN POSITION. Notwithstanding your resignation of
employment, you will continue to serve as Chairman of the Company's Board of
Directors (the "Board"), serving at the discretion of the Board of Directors. In
your role as Chairman, you will not have any operational or management
responsibilities on behalf of the Company. Your duties as Chairman will consist
of presiding over Board and shareholder meetings, such other duties as are
consistent with the Company's Bylaws, and such other duties as may be designated
to you from time to time by the Board. You also agree that you will have no
access to, or involvement in, the Company's decisions and actions concerning its
agreements, relationship or other activities involving ChiLin LLC ("ChiLin"),
any related entity, or any other entity for which you are an officer or
director, and that you will recuse yourself from any discussions or decisions
involving ChiLin or such other entities. Nothing in this Agreement shall affect
your rights, duties and responsibilities as a director of the Company.

         3.       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.

         4.       SEVERANCE PAYMENTS. Although the Company has no obligation to
do so, if you sign this Agreement and allow the release contained herein to
become effective, then the Company will make a one-time, lump sum severance
payment to you in an amount equal to $328,125, which was the amount of your
annual salary while you served as Chief Executive Officer. This severance
payment will be subject to standard payroll deductions and withholdings and will
be paid by the Company within ten (10) days after the Effective Date (as defined
in paragraph 18).

<PAGE>

         5.       STOCK.

                  (A)      2003 OPTION. On August 26, 2003, you were granted an
option to purchase 50,000 shares of stock (the "First Option") and an option to
purchase 250,000 shares of stock (the "Second Option"). On the Separation Date,
the Company will accelerate the vesting of the First Option and Second Option
such that a total of 50,000 shares subject to the First Option and 225,000
shares subject to the Second Option will each become vested and immediately
exercisable. In addition, the vesting terms of the Second Option shall be
modified to provide that so long as you continue to serve as a member of the
Company's Board of Directors, the Second Option will continue to vest at the
rate of 695 shares per month for an additional 36 months. Except as provided
herein, the First Option and Second Option will continue to be governed in all
respects by the terms of the applicable stock option plan documents and the
stock option agreement between you and the Company.

                  (B)      OTHER OPTIONS. During your employment, you were also
granted the following options: (1) an option to purchase 375,000 shares on July
12, 1999 (of which 331,250 shares are currently vested); (2) an option to
purchase 50,000 shares on July 12, 1999 (of which 44,166 shares are currently
vested); (3) an option to purchase 300,000 shares on November 5, 2001 (of which
143,750 shares are currently vested); and (4) an option to purchase 250 shares
on June 7, 2002 (of which 250 shares are currently vested) (collectively, the
"Additional Options"). On the Separation Date, the Company will accelerate the
vesting of all of the Additional Options such that all of the unvested shares
subject to the Additional Options will each become vested and immediately
exercisable. Your rights to exercise any of the shares subject to the Additional
Options will be as provided in the applicable stock option agreement and stock
option plan documents, which provide that such options continue to be
exercisable so long as you are a member of the Board of Directors. Other than
the First Option, the Second Option and the Additional Options, you agree you
have no other options or other rights to purchase capital stock of the Company.
Each of the option share amounts in this paragraph 5 reflect the 4:1 reverse
stock split effective in 2003.

                  (c)      Consistent with the Company's stock option plans, the
Company confirms that the period during which you remain a director of the
Company will be considered a continuation of "employment" for purposes of
exercising all stock options.

         6.       HEALTH INSURANCE. The Company will provide you with your
existing group health insurance coverage, at the Company's expense, for a period
of one year following the Separation Date. Thereafter, 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.

         7.       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 (including an
bonus or pro rata portion of a bonus), in your capacity as an employee of the
Company, with the sole exception of any benefit the right to which has vested
(or will become vested as set forth herein) under the express terms of a Company
benefit plan document or any benefit that you receive in connection with your
service

                                       2
<PAGE>

as a director of the Company. In particular, but without limitation, following
the Separation Date, the Company will no longer pay for an automobile for your
use and you will no longer have an office, assistant or access to other Company
resources, other than as provided to other members of the Board of Directors..
You will be entitled to continued access to your Vitria email account for a
transition period from the Separation Date through March 31, 2004; provided that
during such period such email account shall only be used for matters related to
your activities as Chairman and as a director and for directing persons to a new
email address for your other activities.

         8.       EXPENSE REIMBURSEMENTS. You agree that, within thirty (30)
days of the Effective 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. You will also be
reimbursed pursuant to the Company's regular business practice for any business
expenses (including travel expenses) incurred by you following the Separation
Date in connection with business projects as to which the Company requests your
assistance.

         9.       PROPRIETARY INFORMATION. You hereby acknowledge your
continuing obligation not to use or disclose any of the Company's confidential
or proprietary information without the Company's express authorization.

         10.      RETURN OF COMPANY PROPERTY. By the Effective Date, to the
extent specifically requested by the Company, you agree to return to the Company
documents and other Company property. You are entitled to retain any Company
property and documents necessary for you to fulfill your obligations to the
Company as a member of the Board. You will be afforded a period of 30 days from
the Separation Date to remove your personal items from the Company's offices.

         11.      CONFIDENTIALITY. The provisions of this Agreement will be held
in strictest confidence by you and the Company and will not be publicized or
disclosed in any manner whatsoever; provided, however, that: (a) you may
disclose this Agreement in confidence to your immediate family; (b) the parties
may disclose this Agreement in confidence to their respective attorneys,
accountants, auditors, tax preparers, and financial advisors; (c) the Company
may disclose terms of this Agreement as deemed necessary in its judgment in
accordance with required or appropriate corporate reporting and disclosure
guidelines, after consultation with you as to the nature of any such disclosure;
and (d) the parties may disclose this Agreement insofar as such disclosure may
be necessary to enforce its terms or as otherwise required by law. In
particular, and without limitation, you agree not to disclose the terms of this
Agreement to any current or former Company employee other than your immediate
family.

         12.      INDEMNIFICATION. Nothing herein is intended to reduce or
affect any rights to indemnification that you may have pursuant to your
indemnification agreement with the Company dated as of July 20, 1999, the
Company's Certificate of Incorporation and Bylaws, or by law.

         13.      NONDISPARAGEMENT. Both you and the Company (through its
directors and officers) agree not to disparage the other party, and the other
party's officers, directors,

                                       3

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 or pursuant to
applicable regulatory (e.g., SEC, NASD) obligations.

         14.      COMPANY RELEASE. In exchange for the benefits received
hereunder by the Company to which the Company would not otherwise be entitled,
the Company and its predecessors, successors, parent and subsidiary entities,
affiliates and assigns hereby generally and completely releases you from any and
all claims, liabilities and obligations, both known and unknown, that arise out

<PAGE>

         17.      WAIVER OF UNKNOWN CLAIMS. Except as to claims which have not
been released by the Company as provided herein, the Company and you expressly
waive and relinquish all rights and benefits under California Civil Code section
1542, which provides: "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." Except as to claims which have not been released by the
Company as provided herein, the Company and you expressly waive and relinquish
all rights and benefits under that section and any law of any jurisdiction of
similar effect with respect to the release of claims herein, including but not

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.
