The obligation of the Lender to make the Loan is subject to the due execution and delivery by the Borrower (or the Borrower causing the due execution and delivery) to the Lender of each of the following (all documents to be in form and substance satisfactory to the Lender):

i. This Agreement, the Bridge Note and each other instrument, agreement and document to be executed and/or delivered pursuant to this Agreement and/or the instruments, agreements and documents referred to in this Agreement.

A certified copy of the resolutions of the Board of Directors (or if the Board of Directors takes action by unanimous written consent, a copy of such unanimous written consent containing all of the signatures of the members of the Board of Directors) of the Borrower, dated as of the Closing Date, authorizing the execution, delivery and performance of the Bridge Loan Documents.

b. Absence of Certain Events. The occurrence of a Material Adverse Effect (as defined below) shall not have occurred or be occurring as of the Closing Date.

4. Representations and Warranties of the Borrower. To induce the Lender to make the Loan, the Borrower hereby represents and warrants to the Lender that at and as of the date hereof:

a. The Borrower has been duly incorporated and validly exists and is in good standing under the laws of the state of Nevada, with full corporate power and authority to own, lease and operate its properties and to conduct its business as currently conducted. The Borrower is duly qualified as a foreign entity to do business and is in good standing in every jurisdiction in which its ownership of property or the nature of the business conducted by it makes such qualification necessary and where the failure so to qualify would have a Material Adverse Effect. “Material Adverse Effect” means any material adverse effect on the ability of the Borrower to perform its obligations hereunder or under the Bridge Loan Documents or on the business, operations, properties or financial condition of the Borrower.

b. Each of the Bridge Loan Documents has been duly authorized, validly executed and delivered on behalf of the Borrower and is a valid and binding obligation of the Borrower enforceable against the Borrower in accordance with its terms, subject to limitations on enforcement by general principles of equity and by bankruptcy or other laws affecting the enforcement of creditors’ rights generally, and the Borrower has full power and authority to execute and deliver this Agreement and the Bridge Loan Documents and to perform its obligations hereunder and there under.

c. The execution, delivery and performance of this Agreement and the Bridge Loan Documents will not (i) conflict with or result in a breach of or a default under any of the terms or provisions of (A) the Borrower’s articles of incorporation or by-laws, or (B) any material provision of any indenture, mortgage, deed of trust or other material agreement or instrument to which the Borrower is a party or by which it or any of its material properties or assets is bound, (ii) result in a violation of any material provision of any law, statute, rule, regulation, or any existing applicable decree, judgment or order by any court, Federal or state regulatory body, administrative agency, or other governmental body having jurisdiction over the Borrower, or any of its material properties or assets or (iii) result in the creation or imposition of any material lien, charge or encumbrance upon any material property or assets of the Borrower or any of its subsidiaries pursuant to the terms of any agreement or instrument to which any of them is a party or by which any of them may be bound or to which any of their property or any of them is subject, except, in the cases of (i), (ii) and (iii) above, as would not have a Material Adverse Effect.

d. No consent, approval or authorization of or designation, declaration or filing with any governmental authority on the part of the Borrower is required in connection with the valid execution and delivery of this Agreement or the Bridge Loan Documents.

5. Miscellaneous.

a. The representations and warranties of the Borrower contained herein shall not survive the Closing Date.

b. This Agreement shall be governed by and construed in accordance with the laws of the State of Nevada without giving effect to conflicts of laws principles that would result in the application of the substantive laws of another jurisdiction. This Agreement shall not be interpreted or construed with any presumption against the party causing this Agreement to be drafted.

c. The Bank and Borrower agree to submit to binding arbitration by the American Arbitration Association (the "AAA") of all claims, disputes and controversies (whether in tort, contract, or otherwise, except "core proceedings" under the U.S. Bankruptcy Code) arising between themselves and their respective employees, officers, directors, attorneys and other agents, which relate in any way without limitation to existing and future loans and extensions of credit or requests for additional credit, including by way of example but not by way of limitation the negotiation, collateralization, administration, repayment, modification, default, termination and enforcement of such loans or extensions of credit. Arbitration under this Agreement will be governed by the Federal Arbitration Act and proceed in Virginia in accordance with AAA Rules. Arbitration will be conducted before a single neutral arbitrator selected in accordance with AAA Rules and who shall be an attorney who has practiced commercial law for at least ten years. The arbitrator will determine whether an issue is arbitratable and will give effect to applicable statutes of limitation. Judgment upon the arbitrator's award may be entered in any court having jurisdiction. The arbitrator has the discretion to decide, upon documents only or with a hearing, any motion to dismiss for failure to state a claim or any motion for summary judgment. The institution and maintenance of an action for judicial relief or for any provisional or ancillary remedy shall not constitute a waiver of the right of any party, including the plaintiff, to submit the controversy or claim to arbitration if any other party contests such action for judicial relief. Each request for an extension and all other discovery disputes will be determined by the arbitrator upon a showing that the request is essential for the party's presentation and that no alternative means for obtaining information are available during the initial discovery period. This Agreement does not limit the right of either party to a) foreclose against real or personal property collateral; b) exercise self-help remedies such as setoff or repossession; c) obtain provisional remedies such as replevin, injunctive relief, attachment or the appointment of a receiver during the pendency or before or after any arbitration proceeding; or d) obtain a cognovit judgment, if available. These exceptions do not constitute a waiver of the right or obligation of either party to submit any dispute to arbitration, including those arising from the exercise of these remedies.

d. Any forbearance, failure, or delay by the Lender in exercising any right, power, or remedy shall not preclude the further exercise thereof, and all of the Lender’s rights, powers, and remedies shall continue in full force and effect until specifically waived in writing by the Lender.

e. This Agreement may be executed in two or more counterparts, all of which 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.

f. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement.

g. If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement or the validity or enforceability of this Agreement in any other jurisdiction.

h. This Agreement, the Bridge Note and the instruments referenced herein contain the entire understanding of the parties with respect to the matters covered herein and therein. No provision of this Agreement may be waived or amended other than by an instrument in writing signed by the party to be charged with enforcement.

i. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and assigns. The Borrower shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Lender. Notwithstanding the foregoing, the Lender may assign its rights hereunder to any other person or entity without the consent of the Borrower.

j. This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other person.

k. All remedies of the Lender under this Agreement, the Bridge Note and the other Bridge Loan Documents (i) are cumulative and concurrent, (ii) may be exercised independently, successively or together with other lenders against the Borrower, (iii) shall not be exhausted by any exercise thereof, but may be exercised as often as occasion therefore may occur, and (iv) shall not be construed to be waived or released by the Lender’s delay in exercising, or failure to exercise, them or any of them at any time it may be entitled to do so.

l. All notices required hereunder shall be made in accordance with Section 10 of the Bridge Note.

m. By executing the appropriate signature line below, the Borrower, intending to be legally bound hereby, agrees to the terms and conditions of this Agreement as of the date hereof.

Very truly yours,
