The Glenn A. Chalker Revocable Trust
   Dated June 15, 1993                                             June 14, 2001
Attn:  Glenn A. Chalker, Trustee

Dear Mr. Chalker:

         This Letter Agreement will reflect our understanding that you have
agreed to loan Heartsoft, Inc. (the "Company" or "Heartsoft") an additional
$50,000 (the "Additional Loan") by amending and restating that certain
Convertible Promissory Note by and between the Company and The Glenn A.
Chalker Revocable Trust Dated June 15, 1993 ("Chalker") dated January 24, 2001
in principal amount of $250,000 ("Convertible Note") and the related Security
Agreement by and between the Company and Chalker of even date ("Security
Agreement"). In order to induce Chalker to make the Additional Loan, subject
to the terms of this Letter Agreement, the Company agrees to issue to Chalker
100,000 shares of common stock (the "Additional Shares"), par value $0.0005
per share, of the Company (the "Issuance"), as provided below.

         The Additional Loan and the Issuance will be made in accordance with
the following terms and conditions:

         1.       Chalker shall delivered to the Company a check in the amount
of $50,000. On receipt in full of the foregoing, the Company shall issue and
deliver a certificate representing the Additional Shares to Chalker.

         2.       Upon and simultaneously with the deliveries described in
paragraph 1 above, the Convertible Note and the Security Agreement shall be
deemed to be amended and restated, without further action of the parties, in
the forms attached to this Letter Agreement.

         3.       To induce the Company to amend and restate the Convertible
Note and the Security Agreement and to issue the Additional Shares, Chalker
hereby represents and warrants to the Company that:

                  (a) this Agreement, when executed and delivered by Chalker,
         will constitute a legal, valid and binding obligation enforceable
         against Chalker in accordance with its terms;

<Page>

                  (b) the Additional Shares are being acquired by Chalker for
         investment purposes only, for the account of Chalker and not with the
         view to any distribution thereof;

                  (c) Chalker is an "accredited investor" as that term is
         defined in the Act; and

                  (d) Chalker is aware that the Additional Shares have not been
         registered under the Securities Act of 1933 (the "Act") and its ability
         to sell or dispose of the Additional Shares will be restricted. Chalker
         is subscribing for the Additional Shares with full knowledge of such
         limitation. Chalker acknowledges that it is aware that the Additional
         Shares may not be resold or offered by it for sale in the absence of:
         (i) an effective registration statement under the Act covering the
         Additional Shares; or (ii) an opinion of counsel satisfactory to the
         Company that registration under the Act is not necessary. Chalker
         consents to the placing of a restrictive legend on the Additional
         Shares indicating that the Additional Shares have not been registered
         under the Act, and Chalker understands that the Company will notify its
         transfer agent that the Additional Shares are so restricted.

         4.       Chalker acknowledges that:

                  (a) Chalker has been provided and has read the following
         documents:

                           (i) Annual Reports on Form 10-KSB dated July 14, 2000
                  and September 28, 2000, containing audited financial
                  statements for the fiscal years ending March 31, 2000 and June
                  30, 2000;

                           (ii) Quarterly Report on Form 10-QSB dated November
                  14, 2000, containing unaudited interim financial statements
                  for the period ending September 30, 2000;

                           (iii) Quarterly Report on Form 10-QSB dated February
                  14, 2001 containing unaudited interim financial statements for
                  the period ending December 31, 2000; and

                           (iv) Quarterly Report on Form 10-QSB dated May 15,
                  2001 containing unaudited interim financial statements for the
                  period ending March 31, 2001.

                  (b) Chalker has been provided opportunities to ask questions
         of representatives of the Company regarding the risks and merits of his
         purchase hereunder and to obtain any additional information necessary
         to verify the accuracy of the information contained in the
         above-mentioned documents and to obtain non-confidential public
         information about the Company, its operations and prospects from the
         time of such documents through the date hereof. Upon the basis of
         Chalker reading the above mentioned documents and Chalker's discussion
         with representatives of the Company, Chalker possesses sufficient
         information to understand the risk and merits associated with his
         purchase hereunder and to verify the accuracy of information received;
         provided,

                                        2

         however, that the foregoing shall not in any way waive, prejudice or
         otherwise adversely affect Chalker's right to rely on the Company's
         representations and warranties contained herein or otherwise given in
         connection with the purchase of the Convertible Note and the Additional
         Shares.

         power and authority to enter into this Agreement and to perform its
         obligations under this Agreement.

                  (b) The Additional Shares, when issued and delivered pursuant
         to terms of this Agreement, will be duly authorized, validly issued,
         fully paid and nonassessable.

                  (c) This Agreement and the issuance of the Additional Shares
         contemplated hereby have been duly authorized by all necessary action
