                         COMMON STOCK PURCHASE AGREEMENT


         This Common Stock Purchase Agreement (the "AGREEMENT") is entered into
as of this 26th day of November, 2002 (the "EFFECTIVE DATE") by and between
Persistence Software, Inc., a Delaware corporation (the "COMPANY"), and the
entities listed on SCHEDULE A hereto (each a "PURCHASER" and collectively the
"PURCHASERS").

                                    SECTION 1

                        SALE OF COMMON STOCK AND WARRANT
                        --------------------------------

         1.1 SALE OF COMMON STOCK. Subject to the terms and conditions hereof,
on the Closing Date (as defined below), the Company will issue and sell to each
Purchaser, and each Purchaser will purchase from the Company, that portion of
the Purchased Shares (as defined below) set forth opposite each such Purchaser's
name on SCHEDULE A attached hereto at the Stock Purchase Price (as defined
below). The term "PURCHASED SHARES" shall mean Three Million Seven Hundred Fifty
Eight Thousand Six Hundred Ninety Two (3,758,692) shares of Common Stock, par
value $0.001 per share, of the Company. The aggregate Stock Purchase Price is
Two Million Dollars ($2,000,000) or $0.5321 per share.

         1.2 ISSUANCE OF WARRANT. Subject to the terms and conditions hereof, on
the Closing Date, the Company will issue a warrant to purchase that portion of
the Warrant Shares (as defined below) of the Company (the "WARRANT"), in
substantially the form attached as EXHIBIT A hereto, to each Purchaser as set
forth opposite each such Purchaser's name on SCHEDULE A attached hereto at the
Stock Purchase Price (as defined below). The exercise price per Warrant Share
shall be $0.75 (subject to adjustment for stock splits, stock dividends and the
like and as otherwise provided in the Registration Statement of even date
herewith). The aggregate purchase price of the Warrants shall be $100 (the
"WARRANT PURCHASE PRICE" and together with the Stock Purchase Price, the
"PURCHASE PRICE"). The Purchased Shares and the Warrant Shares are sometimes
referred to herein as the "SECURITIES".

         (a) The aggregate number of Warrant Shares is One Million Two Hundred
Five Thousand One Hundred Thirty (1,205,130) shares of Common Stock of the
Company (subject to adjustment for stock splits, stock dividends and the like).

         (b) For avoidance of doubt, the formula for calculating the number of
Warrant Shares was intended to ensure that the sum of (1) the total number of
shares of Common Stock to be issued to the Purchasers at the Closing (including
the number of shares of Common Stock issuable upon exercise of the Warrants) and
(2) the aggregate number of shares of Common Stock of the Company which all of
the Purchasers may be deemed to beneficially own (as determined in accordance
with the rules of the Securities and Exchange Commission) immediately prior to
the Closing Date is equal to 19.9% of the sum of (x) the number of shares of
Common Stock of the Company issued and outstanding as of October 31, 2002 and
(y) the total number of shares of Common Stock to be issued to the Purchasers at
the Closing (including the number of shares of Common Stock issuable upon
exercise of the Warrants).



         1.3 CLOSING DATE. The closing (the "CLOSING") of the purchase and sale
of the Purchased Shares and the Warrant shall be held at the offices of Venture
Law Group, 2775 Sand Hill Road, Menlo Park, California at 1:45 p.m. on November
26, 2002, or at such other time and place upon which the Company and the
Purchasers shall mutually agree (the date of the Closing is hereinafter referred
to as the "CLOSING DATE").

         1.4 DELIVERY. At the Closing, the Company will deliver to each
Purchaser (i) a binding and irrevocable instruction letter to the Company's
transfer agent (U.S. Stock Transfer Corporation) instructing the transfer agent
to issue a stock certificate to such Purchaser representing the Purchased Shares
and (ii) the Warrant, against payment of the Purchase Price, by wire transfer of
immediately available funds.

         1.5 LEGEND. The certificate or certificates for the Securities (and any
securities issued in respect of or exchange for the Securities) shall be subject
to a legend or legends restricting transfer under the Securities Act of 1933, as
amended (the "SECURITIES ACT") and referring to restrictions on transfer herein,

UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH
RULE 144 OR RULE 701 UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION OF
COUNSEL FOR THE COMPANY STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR
HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY
REQUIREMENTS OF SUCH ACT.

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE HELD BY AN AFFILIATE

PURSUANT TO AN EFFECTIVE REGISTRATION RELATED THERETO OR IN COMPLIANCE WITH RULE
144 OR ITS SUCCESSOR OR PURSUANT TO AN OPINION OF COUNSEL THAT SUCH REGISTRATION
IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.

         The legends set forth above shall be removed and the Company shall
issue a certificate without such legends to the holder of any of the Securities
upon which it is stamped, if (a) the sale of such Security is registered under
the Securities Act, or (b) in connection with the resale of such Security, such
holder provides the Company with an opinion of counsel reasonably acceptable to
the Company, in form, substance and scope customary for opinions of counsel in
comparable transactions, to the effect that a public sale or transfer of such
Security may be made without registration under the Securities Act, or (c) the
Security can be sold to the public pursuant to Rule 144 under the Securities Act
("RULE 144") and a registered broker-dealer provides to the Company a customary

reasonable assurances that such Security can be sold under Rule 144(k) of. Each

Company's 1999 Directors' Stock Option Plan, options to purchase 148,000 shares

warrants, conversion privileges or other contractual rights presently
outstanding to purchase or otherwise acquire any shares of the Company's capital
stock or other securities other than pursuant to the Company's 1994 Stock

other equitable remedies, and to limitations of public policy as they may apply
to the indemnification and contribution obligations pursuant to Section 1.7 of

forward-looking statement was made at the time with a reasonable basis and in
good faith. Any statements made in any such SEC Documents that are or were
required to be updated or amended under applicable law have been so updated or

financial condition or operations of the Company; provided, however that changes

intention of selling or otherwise distributing any of the Securities. Purchaser

of debtors and rules of law governing specific performance, injunctive relief or
other equitable remedies, and to limitations of public policy. The execution and
delivery of the Transaction Documents do not, and the consummation of the
transactions contemplated hereby and thereby will not, conflict with or result
in any violation of any obligation under any judgment, order, decree, statute,
law, ordinance, rule or regulation applicable to the Purchaser.

         3.4 GOVERNMENT CONSENTS, ETC. No consent, approval or authorization of
or designation, declaration or filing with any governmental authority on the

filings required the Exchange Act.

                      POST-CLOSING COVENANTS OF THE COMPANY
                      -------------------------------------

         6.1 ELECTION OF DIRECTOR. For so long as the Purchasers beneficially
own at least 11% of the issued and outstanding stock of the Company, the
Purchasers shall have right to designate one member of the Board of Directors of
the Company (the "PURCHASER DESIGNEE") (and to fill the vacancy of such member
in the event of the resignation, death or removal of such member). The Purchaser
Designee shall be required to complete a questionnaire in the same form as has
been executed by all other directors for the Company. Subject to the fiduciary
obligations of the Board of Directors to the Company's stockholders based on
advice of legal counsel and the directors' review and approval (not to be
unreasonably withheld) of such questionnaire and any other relevant information,
in each case as applied on a consistent basis to each other director, the
Company shall (i) nominate and recommend in the Company's proxy statement the
Purchaser Designee as a Class III director of the Company's Board of Directors
at each meeting of stockholders of the Company where the class of which the
Purchaser Designee is a member is up for election, and (ii) in the event that
the Purchaser Designee shall resign or be removed as a director for any reason
during the period that this Section 6.1 is in effect, fill the vacancy resulting
thereby with a Purchaser Designee. The Company shall provide all rights and
benefits of indemnity to each Purchaser Designee as are provided to other
outside directors of the Company. In the event of any business conflict of
interest between the Purchaser Designee and another director or proposed
director, the Board shall favor retaining the Purchaser Designee over such other
director, and in any event if the Board of Directors does not approve a
particular individual as the Purchaser Designee for the slate of Class III
directors as a result of the process described in the second sentence of this
paragraph, then the Purchasers shall designate a different Purchaser Designee,
whom shall be subject to the same review and approval process.

         6.2 CURRENT REPORT. As soon as reasonably practicable but in no event
later than November 27, 2002, the Company shall file with the SEC on Form 8-K, a
pro forma balance sheet (reflecting the effect of this Agreement and the
transactions contemplated hereby) for the period ended September 30, 2002, that
shows compliance with the Nasdaq stockholders equity listing requirements.

         6.3 GOOD STANDING CERTIFICATES. The Company is currently not in good
standing as a foreign corporation in Texas. The Company shall deliver to the
Purchasers within five (5) business days after Closing a good standing
certificate (with regard to both corporate status and franchise taxes) from the
relevant authority in the State of Texas.
