ARTICLE 1

REPURCHASE OF SHARES

1.1                               Purchase and Sale.  At the Closing, the Shareholder shall sell, convey and deliver to Parent the Shares, free and clear of any and all claims, liens, pledges, options, charges, security interests, encumbrances or other rights of third parties, and Parent shall purchase and accept such Shares from the Shareholder for $0.0001 per share, or an aggregate purchase price of Eleven Thousand Nine Hundred Ninety-seven and 98/100 ($11,997.98) (the “Purchase Price”).

1.2                               Closing; Delivery.  The closing of the purchase and sale of the Shares pursuant to this Agreement (the “Closing”) shall occur immediately after the Effective Time (as defined in the Merger Agreement) (i.e., immediately after the time of the closing of the Merger).  At the Closing, (i) the Shareholder shall deliver to Parent the Shares in certificate form, and (ii) Parent shall deliver the Purchase Price to the Shareholder, by check or wire transfer, as designated by the Shareholder. Each of Parent’s and the Shareholder’s obligation to consummate the transactions contemplated hereby at the Closing is independent, absolute and irrevocable and not subject to any condition precedent.  Upon the consummation of the Closing, the Shares shall be canceled and returned to the authorized but unissued shares of the Company.

ARTICLE 2

REPRESENTATIONS AND WARRANTIES OF THE SHAREHOLDER

In connection with the purchase and sale of the Shares, the Shareholder makes the following representations and warranties for the benefit of Parent:

2.1                               Authorization.  The Shareholder has the legal capacity and full power and authority to execute and deliver this Agreement and to perform the Shareholder’s obligations hereunder, and has taken or shall take, as applicable, all actions necessary in order to execute, deliver and perform this Agreement and to consummate the transactions contemplated by this Agreement.

2.2                               Due Execution and Delivery.  The Shareholder represents that this Agreement has been duly executed and delivered by her and constitutes the legal, valid and binding obligation of the Shareholder enforceable in accordance with the terms hereof (subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles).

2.3                               Title to Shares.  The Shareholder owns all right, title and interest (legal and beneficial) in and to the Shares, free and clear of all Liens other than restrictions under federal and state securities laws; provided that none of such restrictions under federal or state securities laws in any manner restrict or otherwise impede the Shareholder’s ability to sell the Shares to Parent as contemplated hereby.  Upon delivery of the Shares to Parent and payment to the Shareholder of the Purchase Price, Parent will acquire good, valid and marketable title to such Shares free and clear of all Liens other than (i) restrictions under federal and state securities laws, and (ii) any Liens created by Parent.  For the purposes of this Agreement, “Lien” shall mean any lien, pledge, claim, security interest, encumbrance, charge, restriction or limitation of any kind, whether arising by agreement, operation of law or otherwise.  The Shares represent approximately 86.96% of the outstanding shares of capital stock in Parent, on a fully-diluted basis, as calculated immediately prior to the closing of the Merger Agreement.

2.4                               No Conflicts.  The execution and delivery of this Agreement and the performance by the Shareholder hereunder does not and will not result in the breach or violation of any of the terms or provisions of, or constitute a default under, or accelerate the performance required by the terms of any indenture, mortgage, deed of trust, loan agreement or any other agreement or instrument to which she is a party or by which she is bound, nor will any such action result in any violation of the provisions of, or in any way conflict with, any law, statute or other legal requirement or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Shareholder or her property.

2.5                               Litigation.  There is not pending, threatened in writing or, to the Shareholder’s knowledge, otherwise threatened against the Shareholder (or any affiliate or related person thereof) any action, suit or proceeding at law or in equity before any court, tribunal, governmental body, agency or official or any arbitrator relating to the Shares or that might affect the legality, validity or enforceability against the Shareholder of this Agreement or the Shareholder’s ability to perform her obligations hereunder.  There is no lawsuit, proceeding or investigation pending or threatened against the Shareholder that would, if adversely determined, prevent or delay the consummation of the transactions contemplated hereby.

2.6                               Information Regarding the Shares.  The Shareholder has been furnished with such documents, materials and information as the Shareholder deems necessary or appropriate for evaluating the financial condition of Parent, including information regarding the Merger and a copy of the Merger Agreement, and has had the opportunity to ask questions of, and receive answers from, the officers of Parent, concerning Parent and the terms and conditions of the Merger.  The Shareholder acknowledges and explicitly agrees that although she has received certain information from Parent as to its financial condition and other matters and the Merger, the Shareholder understands that, upon completion of the Merger, the Shares will be worth more than the Purchase Price to be paid to the Shareholder but that the Shareholder is desirous for her own reasons to pursue the sale of the Shares at the Purchase Price to be paid to Shareholder by Parent. Further, the Shareholder acknowledges that, in the months following the

2

Merger, Parent may attempt to consummate a public offering, which public offering may be at a price substantially higher than the price per share of the Shares.

2.7                               No Broker.  The Shareholder has not, directly or indirectly, dealt with anyone acting in the capacity of a finder or broker, nor has the Shareholder incurred any obligations for any finder’s or broker’s fee or commission, in connection with the transactions contemplated by this Agreement.

ARTICLE 3

3.2                               Due Execution and Delivery.  Parent represents that this Agreement has been duly executed and delivered by it and constitutes the legal, valid and binding obligation of Parent enforceable in accordance with the terms hereof (subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles).
