    The Board has determined that Mr. Shanahan qualifies as an "audit committee

Commission.

DIRECTOR NOMINATION

    CRITERIA FOR BOARD MEMBERSHIP. In selecting candidates for appointment or
re-election to the Board, the nominating committee (the "Nominating Committee")
considers the appropriate balance of experience, skills and characteristics
required of the Board of Directors, and seeks to insure that at least a majority
of the directors are independent under the rules of the Nasdaq Stock Market,
that members of the Company's audit committee meet the financial literacy and
sophistication requirements under the rules of the Nasdaq Stock Market and at
least one of them qualifies as an "audit committee financial expert" under the
rules of the Securities and Exchange Commission. Nominees for director are
selected on the basis of their depth and breadth of experience, integrity,
ability to make independent analytical inquiries, understanding of the Company's
business environment, and willingness to devote adequate time to Board duties.

    STOCKHOLDER NOMINEES. The Nominating Committee will consider written
proposals from stockholders for nominees for director. Any such nominations
should be submitted to the Nominating Committee c/o the Secretary of the Company
and should include the following information: (a) all information relating to
such nominee that is required to be disclosed pursuant to Regulation 14A under
the Securities Exchange Act of 1934 (including such person's written consent to
being named in the proxy statement as a nominee and to serving as a director if
elected); (b) the names and addresses of the stockholders making the nomination
and the number of shares of the Company's Common Stock which are owned
beneficially and of record by such stockholders; and (c) appropriate
biographical information and a statement as to the qualification of the nominee,
and should be submitted in the time frame described in the Bylaws of the
Company.

    PROCESS FOR IDENTIFYING AND EVALUATING NOMINEES. The Nominating Committee
believes the Company is well-served by its current directors. In the ordinary
course, absent special circumstances or a material change in the criteria for

                                       3


Board membership, the Nominating Committee will renominate incumbent directors
who continue to be qualified for Board service and are willing to continue as
directors. If an incumbent director is not standing for re-election, or if a
vacancy on the Board occurs between annual stockholder meetings, the Nominating
Committee will seek out potential candidates for Board appointment who meet the
criteria for selection as a nominee and have the specific qualities or skills
being sought. Director candidates will be selected based on input from members
of the Board, senior management of the Company and, if the Nominating Committee
deems appropriate, a third-party search firm. The Nominating Committee will
evaluate each candidate's qualifications and check relevant references; in
addition, such candidates will be interviewed by at least one member of the
Nominating Committee. Candidates meriting serious consideration will meet with
all members of the Board. Based on this input, the Nominating Committee will
evaluate which of the prospective candidates is qualified to serve as a director
and whether the committee should recommend to the Board that this candidate be
appointed to fill a current vacancy on the Board, or presented for the approval
of the stockholders, as appropriate.

    The Company has never received a proposal from a stockholder to nominate a
director. Although the Nominating Committee has not adopted a formal policy with
respect to stockholder nominees, the committee expects that the evaluation
process for a stockholder nominee would be similar to the process outlined
above.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

    Section 16(a) of the Exchange Act requires the Company's directors,
executive officers and persons who own more than 10% of the Company's Common
Stock (collectively, "Reporting Persons") to file with the Securities and
Exchange Commission initial reports of ownership and changes in ownership of the
Company's Common Stock. Reporting Persons are required by SEC regulations to
furnish the Company with copies of all Section 16(a) reports they file. To the
Company's knowledge, based solely on its review of the copies of such reports
received or written representations from certain Reporting Persons that no
reports were required, the Company believes that during the year ended December
31, 2003 all Reporting Persons complied with all applicable filing requirements.

CODE OF ETHICS

    Persistence has adopted a code of ethics that applies to all officers and
employees, including its principal executive officer, principal financial
officer and controller. This code of ethics is included as Exhibit 14.1 to the
Annual Report and available upon request to Persistence Software, Inc., 1720

(1)   The potential realizable value illustrates a value that might be realized
      upon exercise of the options immediately prior to the expiration of their
      terms, assuming the specified compounded rates of appreciation of the
      market price per share from the date of grant to the end of the option
      term, less the exercise price. Actual gains, if any, on stock option
      exercise are dependent upon a number of factors, including the future
      performance of the Common Stock and the timing of option exercises, as
      well as the optionees' continued employment throughout the vesting period.
      There can be no assurance that the amounts reflected in this table will be
      achieved.
(2)   The Company granted stock options representing 241,100 shares to employees
      in 2003. All grants were made under the 1997 Stock Plan.
(3)   The exercise price may be paid in cash, in shares of Common Stock valued
      at fair market value on the exercise date or through a cashless exercise
      procedure involving a same-day sale of the purchased shares.
(4)   This option vests at the rate of 1/4th of the total number of shares on
      the first anniversary of April 1, 2004, the vesting commencement date, and
      1/48th of the total shares on each monthly anniversary of the vesting
      commencement date thereafter.
(5)   This option vests at the rate of 1/2 of the total number of shares on the
      first anniversary of December 18, 2004, the vesting commencement date, and
      1/24th of the total shares on each monthly anniversary of the vesting
      commencement date thereafter.
(6)   This option vests at the rate of 1/4th of the total number of shares on
      the first anniversary of December 18, 2004, the vesting commencement date,
      and 1/48th of the total shares on each monthly anniversary of the vesting
      commencement date thereafter.

COMPENSATION OF DIRECTORS

    Directors do not currently receive cash compensation for their services as

2,000 shares of Common Stock (the "First Option") on the date of his or her
election or appointment to the Board of Directors, (ii) an additional option to
purchase 2,000 shares of Common Stock (the "Second Option") on the one year
anniversary of his or her election or appointment as a director, and (iii) an
additional option (each, a "Subsequent Option") to purchase 1,000 shares of
Common Stock on the first day of each fiscal year after the date of grant of the
Second Option. All such options granted to Preexisting Outside Directors and New
Outside Directors are fully vested at the date of the grant, have an exercise

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND
RELATED STOCKHOLDER MATTERS

COMMON STOCK OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

    The following table sets forth information that has been provided to the
Company with respect to beneficial ownership of shares of the Company's Common
Stock as of February 29, 2004 for (i) each person who is known by the Company to
own beneficially five percent or more of the outstanding shares of Common Stock,
(ii) each director of the Company, (iii) each of the Named Executive Officers,
and (iv) all directors and executive officers of the Company as a group. The
applicable percentage of ownership for each stockholder is based on 2,713,918
shares of Common Stock outstanding as of February 29, 2004, in each case
together with applicable options for that stockholder. Shares of Common Stock
issuable upon exercise of options and other rights beneficially owned that are
exercisable on or before April 29, 2004 are deemed outstanding for the purpose
of computing the percentage ownership of the person holding those options and
other rights but are not deemed outstanding for computing the percentage
ownership of any other person.

    Except as otherwise noted, the address of each person listed in the table is
c/o Persistence Software, Inc., 1720 South Amphlett Boulevard, Third Floor, San
Mateo, California, 94402. Beneficial ownership is determined in accordance with
the rules of the Securities and Exchange Commission and is based on the
individual's ability to exercise voting and investment power with respect to
shares. To our knowledge, except under applicable community property laws or as
otherwise indicated, the persons named in the table have sole voting and sole
investment control with respect to all shares beneficially owned.
