EXHIBIT 99.2
VOTING AGREEMENT
----------------
THIS VOTING AGREEMENT is dated as of May 20, 2000 (this "Agreement"), among
---------
Active Software, Inc., a Delaware corporation (the "Company"), and each other
-------
party who is a signatory hereto (each a "Stockholder" and collectively the
-----------
"Stockholders"). Capitalized words not otherwise defined in this Agreement
------------
shall have the meaning set forth in the Merger Agreement.
WHEREAS, each Stockholder desires that, the Company, Parent and Merger Sub
enter into an Agreement and Plan of Merger dated as of the date hereof (as the
same may be amended or supplemented, the "Merger Agreement"), pursuant to which
----------------
it is intended that the Company shall merge with Merger Sub ("Merger");
------
WHEREAS, as of the date hereof, each Stockholder is beneficial owner of,
and has the right to vote and dispose of the number of shares of Parent Common
Stock which is set forth opposite such Stockholder's name in Schedule A hereto;
----------
WHEREAS, as the Company has solicited proxies from the individuals and
entities as indicated on Schedule A hereto; and
----------
WHEREAS, each Stockholder is executing this Agreement as an inducement to
the Company to enter into and execute the Merger Agreement;
NOW, THEREFORE, in consideration of the execution and delivery by the
Company of the Merger Agreement and the representations, warranties, covenants,
conditions and agreements contained herein and therein, the parties agree as
follows:
Section 1. Representations and Warranties of Stockholders. Each
----------------------------------------------
Stockholder, severally, and not jointly, represents, warrants and covenants to
the Company as of the date of this Agreement, as follows:
(a) Stockholder is the record holder and/or beneficial owner of the
number of shares of Parent Common Stock set forth opposite such
Stockholder's name in Schedule A hereto, as such Schedule is amended or
----------
modified pursuant to Section 5 hereof (the "Stockholder's Shares" or
--------- --------------------
"Shares"). Except for the Stockholder's Shares, Stockholder is not the
------
record or beneficial owner of any other shares of Parent Common Stock.
(b) This Agreement has been duly authorized, executed and delivered
by the Stockholder and, assuming due execution and delivery of this
Agreement by the other parties hereto, shall constitute the legal, valid
and binding obligation of the Stockholder, enforceable against the
Stockholder in accordance with its terms (except as enforceability
<PAGE>
may be limited by applicable bankruptcy, insolvency, moratorium or similar
laws affecting creditors' rights generally or by principles governing the
availability of equitable remedies). Neither the execution and delivery of
this Agreement nor the performance by the Stockholder of this Agreement
will result in a violation of, or a default under, or conflict with, any
contract, trust, commitment, agreement, understanding, arrangement or
restriction of any kind to which the Stockholder is a party or bound or to
which the Stockholder's Shares are subject. No trust of which the
Stockholder is a trustee requires the consent of any beneficiary to the
execution and delivery of this Agreement or to the consummation of the
transactions contemplated hereby. If the Stockholder is married and the
Stockholder's Shares constitute community property, this Agreement has been
duly authorized, executed and delivered by, and constitutes a valid and
binding agreement of, the Stockholder's spouse, enforceable against such
person in accordance with its terms (except as enforceability may be
limited by applicable bankruptcy, insolvency, moratorium or similar laws
affecting creditors' rights generally or by principles governing the
availability of equitable remedies). The execution and delivery of the
Agreement by the Stockholder and performance of this Agreement will not
violate, or require any consent, approval, or notice under, any provision
of any judgment, order, decree, statute, law, rule or regulation applicable
to the Stockholder or the Stockholder's Shares.
(c) The Stockholder understands and acknowledges that the Company is
entering into the Merger Agreement in reliance upon the Stockholder's
execution and delivery of this Agreement.
(d) Each Stockholder is acting individually and not part of a "group"
in Section 13(d) of the Exchange Act.
Section 2. Representations and Warranties of the Company. The Company
---------------------------------------------
represents, warrants and covenants to each Stockholder, as of the date of this
Agreement, as follows:
(a) This Agreement and the Merger Agreement have been duly and
validly executed and delivered by the Company, as applicable, and assuming
due execution and delivery of this Agreement by the other parties thereto,
shall constitute the legal, valid and binding obligation of the Company, as
applicable, enforceable in accordance with their terms, except as
enforceability may be limited by bankruptcy and other similar laws and
general principles of equity. Neither the execution and delivery of this
Agreement or the Merger Agreement nor the consummation of the Merger or the
transactions contemplated hereby will result in the violation of, or a
default under, or conflict with, any contract, trust, commitment,
agreement, understanding, arrangement or restriction of any kind to which
the Company is a party or bound. Execution and delivery by the Company of
this Agreement and the Merger Agreement and performance of the transactions
contemplated thereby will not violate or require any consent, approval,
notice under any provision of any judgment, order, decree, statute, law,
rule or regulation applicable to the Company, except for (i) applicable
requirements, if any, of the
<PAGE>
Exchange Act, the Securities Act, the Blue Sky Laws and the HSR Act, in
each case, including rules and regulations promulgated thereunder and (ii)
the Certificate of Merger.
(b) The Company understands and acknowledge that each Stockholder is
entering into this Agreement in reliance upon the covenant and agreement of
the Company to perform their respective covenants and obligations under the
Merger Agreement in accordance with its terms.

----------------
and not jointly, that it shall, and shall cause the holder of record of any
Shares beneficially owned by such Stockholder on any applicable record date and

any written consent of the holders of Parent Common Stock, (a) if a meeting is

purposes of establishing a quorum, and (b) vote or consent (or cause to be voted
or consented), in person or by proxy, all Shares, and any other voting
securities of the Company (whether acquired heretofore or hereafter) that are
beneficially owned or held of record by such Stockholder or as to which such
Stockholder has, directly or indirectly, the right to vote or direct the voting,
in favor of the issuance of shares of Parent Common Stock in connection with the
Merger.

hereby consents to the entry of stop transfer instructions by the Parent of
any transfer of such Stockholder's Shares, unless such transfer is made in
compliance with this Agreement.
