                  WHEREAS, on January 14, 2000 the Agreement whereby the Company
issued and sold to Wolfpack and Wolfpack purchased and acquired One Hundred
Fifty Thousand (150,000) shares (the "Shares") of the authorized but unissued
common stock, $.001 par value per share (the "Common Stock") of the Company

Agreement, the Company conducted a 10:1 forward stock split (the "Stock
Split")of its common stock;

amendment, by both the Company and the Purchaser, or, in the case of a waiver,
by the party against whom enforcement of any such waiver is sought. No waiver of
any default with respect to any provision, condition or requirement of this
Agreement shall be deemed to be a continuing waiver in the future or a waiver of
any other provision, condition or requirement hereof, nor shall any delay or
omission of either party to exercise any right hereunder in any manner impair
the exercise of any such right accruing to it thereafter.

         Section 3.5. Headings.  The headings herein are for convenience only,
                      --------
do not constitute a part of this Agreement and shall not be deemed to limit or

by ant party without the prior written consent of all the parties hereto. This

under this Agreement.

                      ----------------------------

and assigns and is not for the benefit of, nor may any provision hereof be
enforced by, any other person.

                      -------------
governed by and construed and enforced in accordance with the internal laws of

                                       -----------
covenants of the parties contained in Article IV, the default and remedies
                                      ----------
contained in Article V and this Article IX shall survive the Closing (or any
             ---------          ----------
earlier termination of this Agreement).


         Section 3.10. Counterpart Signatures. This Agreement may be executed in
                       ----------------------
two or more counterparts, all of which when taken together shall be considered
one and the same agreement and shall become effective when counterparts have
been signed by each party and delivered to the other party, it being understood
that both parties need not sign the same counterpart. In the event that any
signature is delivered by facsimile transmission, such signature shall create a
valid and binding


                                       4
<PAGE>

obligation of the party executing (or on whose behalf such signature is
executed) the same with the same force and effect as if such facsimile signature
page were an original thereof.

         Section 3.11.  Publicity. The Company and the Purchaser shall consult
                        ---------
with each other in issuing any press releases or otherwise making public

party shall issue any such press release or otherwise make any such public
statement without the prior written consent of the other, which consent shall
not be unreasonably withheld or delayed.

         Section 3.12.  Severability. In case any one or more of the provisions
                        ------------
of this Agreement shall be invalid or unenforceable in any respect, the validity
and enforceability of the remaining terms and provisions of this Agreement shall
not in any way be affecting or impaired thereby and the parties will attempt to
agree upon a valid and enforceable provision which shall be a reasonable
substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.

         Section 3.13. Remedies. In addition to being entitled to exercise all
                       --------
rights provided herein or granted by law, including recovery of damages, the
Purchaser will be entitled to specific performance of the obligations of the
Company under this Agreement and the Company will be entitled to specific
performance of the obligations of the Purchaser hereunder with respect to the
subsequent transfer of Shares. Each of the Company and the Purchaser agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of any breach of its obligations described in the foregoing sentence and
hereby agrees to waive in any action for specific performance of any such
obligation the defense that a remedy at law would be adequate.
