   Your main terms and conditions are set out in this document. These, and the

April 9, 2001

Jay Shiveley

Dear Jay:

This letter sets forth the substance of the agreement (the "Agreement") between
Vitria Technology, Inc. (the "Company") and you in connection with your
potential service as a part-time employee.

SUSPENSION DATE.  Your last day of full-time work with the Company as Senior
---------------
Vice President of Sales was February 26, 2001 (the "Suspension Date").  From the
Suspension Date until the Effective Date (as defined below under the ADEA Waiver
heading), you have been and will remain an employee of the Company on an unpaid
leave of absence (the "Leave Period").  During the Leave Period, except to the
extent specified in this Agreement (and in that case only if the Agreement
becomes effective), you will not receive any salary, you will not accrue any
vacation benefits or other paid time off, and the vesting of any stock options,
or lapse of any Company repurchase right on purchased stock, will be suspended.
If the Effective Date does not occur prior to April 21, 2001, then unless
otherwise elected at the sole discretion of the Company, your employment will be
considered to have terminated effective as of February 26, 2001, and you will
not receive any of the benefits set forth below.  In addition, if you do not
accept this Agreement, the Company will exercise its repurchase right with
respect to any Company shares that you obtained via an early exercise provision.
During the Leave Period, you will not be required, nor are you authorized, to
conduct any activities on behalf of the Company except as specifically requested
by the Company.

CONTINUED BENEFITS.  In consideration for signing this Agreement and subject to
------------------
your continued compliance with its terms, the Company agrees to provide you with
the following benefits:

 .  From February 26, 2001 until the earlier of June 26, 2001, or termination of
   your employment, you will receive salary, for part-time service, of a total
   amount of $33,000, less standard deductions and withholdings (the "Part-Time
   Employment Period"). This amount will be paid on the Company's normal payroll
   dates (twice a month) on 8 gross payments (i.e., prior to standard deductions
   and withholdings) of $4,125 each. Within 10 days after the Effective Date,
   the Company will pay you the payments which would have been due by the
   Effective Date if this Agreement had been signed and had become effective on
   February 26, 2001 (assuming an April 21, 2001 Effective Date and payment
   date, you would receive $16,500 (prior to standard deductions and
   withholdings) for the first 4 payments).

 .  The Company will continue to retain you on the Company's medical, dental,
   vision, and life insurance plans, at no cost to you, during the Part-Time
   Employment Period. Thereafter, you and your dependents may elect continued
   coverage under COBRA.
<PAGE>

 .  Upon the Effective Date, you will continue to vest (pursuant to the vesting
   schedule set forth herein) in 100,000 shares of Company stock pursuant to
   your option grant number 21 dated October 20, 1997 (the "Continued Option").
   The Continued Option will vest at a rate of 25,000 shares per month at the
   end of each full month of service during the Part-Time Employment Period;
   provided, however, that if the Effective Date occurs prior to or on April 21,
   2001, you will vest on the Effective Date in 25,000 shares of the Continued
   Option and (assuming continued employment) you will vest in an additional
   25,000 shares on April 30, 2001. You will not sell, transfer or otherwise
   dispose of the 100,000 shares acquired under the Continued Option until
   February 27, 2002 ("lock-up agreement"). The Company may impose an
   appropriate legend on any stock certificate evidencing those shares, and may
   give its transfer agent stop transfer restrictions to enforce this lock-up
   agreement. The Company will remove the legends and stop transfer restrictions
   on or before February 26, 2002 so that you could sell those shares on or
   after February 27, 2002 without obtaining instructions from the Company to
   its transfer agent or an opinion of counsel. Upon termination of the Part-
   Time Employment Period, the Company shall cancel any options of the Continued
   Option that remain unvested. You may exercise the Continued Option until 90
   days after termination of the Part-Time Employment Period (assuming
   employment through June 26, 2001, the last day for exercise would be
   September 24, 2001).

 .  With the exception of the 100,000 shares from Grant No. 21 (described in the
   preceding paragraph), you acknowledge that your previous option grants (Grant
   Nos. 21, 129 and 320) terminated vesting as of the Suspension Date and are
   not subject to any additional vesting. You further acknowledge that under
   Grants Nos. 21, 129 and 320, you had vested in 460,000 shares as of the
   Suspension Date.

 .  Notwithstanding your obligation to return Company property (as set forth
   below), you may retain the Company-provided Palm Pilot; provided, however,
   that you agree to delete from the Palm Pilot all contact information for
   Company employees and all other Company proprietary information. You further
   agree that the Company proprietary information previously provided to you for
   use on your Palm Pilot will not be used for business purposes or for
   activities that would be competitive with the activities of the Company.

 .  You and the Company disagree as to the amount, if any, owed to you for your
   2000 and 2001 incentive compensation. You and the Company have mutually
   agreed that if you sign this Agreement, the Company will pay you a lump sum
   payment of $137,000, less standard deductions and withholdings, in full
   satisfaction of the amount, if any, owed for your 2000 and 2001 incentive
   compensation. This payment will be paid within ten (10) days of the Effective
   Date.

 .  You will receive a lump sum payment of $67,000, less standard deductions and
   withholdings, on February 28, 2002 if: (i) you are in material compliance
   with your obligations to the Company as set forth in this Agreement, your
   Employment Agreement dated August 18, 1997, and your Employee Proprietary
   Information and Inventions Agreement dated August 18, 1997; and (ii) you
   execute an additional release in the form attached as Exhibit B. You will be
   deemed to have materially complied with the obligations in clause (i) unless:
   (A) the Company has given notice of a material breach of those obligations
   within 10 days after an officer of the Company becomes aware of facts which
   reasonably would constitute a material breach of
<PAGE>

those obligations; and (B) either the asserted breach cannot be cured or you do
not cure the asserted breach within 10 days after you receive the notice.

CONTINUED EMPLOYMENT.  During the Part-Time Employment Period, you will continue
--------------------
as a part-time employee of the Company, but will no longer be in the position of
Vice President of Sales and you will not be considered to be an officer of the
Company.  During this period, you will provide all necessary assistance to, and
cooperation with the Company and you will undertake such assignments as may be
requested by an officer of the Company from time to time in writing ("Work
Assignments"); provided, that in no event shall you be required to provide
services to the Company in excess of twenty (20) hours during any week.  During
the Part-Time Employment Period, the Company may terminate your employment for
any material breach of the terms of this Agreement (including Exhibits A, B and
C).  In order to terminate your employment for material breach, (A) the Company
must have given you notice of a material breach of those obligations within 10
days after any officer of the Company becomes aware of facts which reasonably
would constitute a material breach of those obligations; and (B) either the
asserted breach cannot be cured or you do not cure the asserted breach within 10
days after you receive the notice.

ADEA WAIVER.  In accordance with the Age Discrimination in Employment Act (the
-----------
"ADEA"), you have had a period of 21 days in which to consider the terms of this
Agreement and 7 days, after signing this Agreement, in which you may choose to
revoke your acceptance of its terms.  You are advised to consult an attorney
before waiving any rights that you may have under the ADEA. Eight days after
both parties have signed this Agreement (the "Effective Date"), its terms will
automatically become effective unless you have revoked your acceptance of the
terms of this Agreement between the date you and the Company sign this letter
and the Effective Date.

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 Suspension Date.

EXPENSE REIMBURSEMENTS.  You agree that you have submitted your final documented
----------------------
expense reimbursement claim form to myself, reflecting all business expenses you
incurred through the Suspension Date.  The Company will reimburse you for these
expenses pursuant to its regular business practice.  Following the Suspension
Date, you will not be reimbursed for any expenses incurred on behalf of the
Company, except as specifically agreed in writing in connection with any Work
Assignment.

RETURN OF COMPANY PROPERTY.  With the exception of the Company-provided Palm
--------------------------
Pilot (as described above), you agree to return to the Company on or prior to
the Effective Date, all Company property which you have had in your possession
at any time, including, but not limited to, Company files, notes, drawings,

positioning materials, customer information, contract information, financial
information, specifications, computer-recorded information, tangible property

------------------------
employee of the Company after the Suspension Date, other than as provided in
writing in connection with a Work Assignment.  You hereby agree not to represent

including any employee of the Company, unless authorized by the Company, in
writing, to do so.

PROPRIETARY INFORMATION OBLIGATIONS.  Both during and after the term of your
-----------------------------------
employment, you will refrain from any use or disclosure of the Company's
proprietary or confidential information or materials, and you acknowledge that
