     WHEREAS, the Company desires to obtain Consultant's consulting services in
connection with the Consultant's identification and introduction of a suitable
public company (the "Public Company") to the Company and assistance in closing a
reverse merger transaction (the "Merger") between the Company and such Public
Company and the other matters as set forth in this Agreement; and

     WHEREAS, Consultant desires to provide such services to the Company
directly for a fee that will compensate Consultant for time spent for services
rendered and costs advanced by Consultant as contemplated in this Agreement.

     NOW, THEREFORE, in consideration of the foregoing and of the mutual
promises and conditions hereinafter set forth, the parties agree as follows:

     1. RETENTION OF CONSULTANT. The Company hereby engages and retains

Consultant believes would be suitable for the Company to effect a Merger with;

     3. PAYMENT FOR SERVICES. The Company shall pay Consultant for the services
rendered hereunder by issuing Consultant 225 restricted shares of its Common

Shares shall be deemed to be $9,000, or $40 per share.

          3.1 The Shares will vest in Consultant and the Company will transfer

          3.2 The issuance of the Shares shall be deemed full and complete
consideration for the services to be rendered by Consultant under this
Agreement. The Company will reimburse Consultant for all direct expenses
incurred by Consultant in performing such services. Consultant shall obtain the
approval of the Company prior to incurring any expenses. Consultant will tender
requests for reimbursement to the Company and the Company will make the
reimbursement to Consultant within ten (10) days after its receipt of written
notification.

     4. CONSULTANT'S TIME COMMITMENT; NON-EXCLUSIVE AGREEMENT. Consultant shall
devote such time as reasonably requested by the Company for consultation, advice

a consultant or otherwise other than Consultant to render services similar or
dissimilar in nature to those rendered or to be rendered by Consultant under
this Agreement.

that of Consultant acting as an independent contractor. The parties acknowledge
and agree that Consultant shall have no authority to, and shall not, bind the

providing legal or accounting services or services as a broker/dealer and such
services must be obtained by the Company from other parties.

     6. NONDISCLOSURE OF CONFIDENTIAL INFORMATION. Consultant shall maintain as
secret and confidential all valuable information heretofore or hereafter
acquired, developed or used by the Company relating to its business, operations,
employees and customers that may give the Company a competitive advantage in its
industry (all such information is hereinafter referred to as "Confidential
Information"). The parties recognize that, by reason of Consultant's duties
under this Agreement, Consultant may acquire Confidential Information.
Consultant recognizes that all such Confidential Information is the property of
the Company. During the term of Consultant's engagement by the Company,
Consultant shall exercise all due and diligent precautions to protect the
integrity of any or all of the Company's documents containing Confidential
Information. In consideration of the Company entering into this Agreement,
Consultant shall not, directly or indirectly, use, publish, disseminate or
otherwise disclose any Confidential Information obtained during Consultant's
engagement by the Company without the prior written consent of the Company. The
parties agree that this Paragraph 6 shall survive the termination of this
Agreement.

     7. COMMUNICATIONS WITH CONSULTANT. Consultant will not independently
conduct a due diligence review of the Company and will, to a great extent, be
relying upon information provided by the Company in rendering services under
this Agreement.

     8. NONCIRUMVENTION. The Company shall pay Consultant the compensation set
forth in this Agreement if, after the termination of the Agreement, it enters
into a Merger or other transaction with any of such Public Companies to whom
Consultant, directly or indirectly through a third party, has introduced the
Company during the term of this Agreement

     9. EXCULPATION OF LIABILITY AND INDEMNIFICATION. All decisions with respect

file a registration statement with the Securities and Exchange Commission in the
United States relating to an offering for its own account or the account of
others under the Securities Act of 1933, as amended, of any of its equity
securities, then the Company shall offer send to Consultant a written notice of

Consultant shall so request in writing, the Company will include in such
registration statement any or all of the Shares that Consultant requested to be
