President

Ladies and Gentlemen:

Reference is made to that certain Loan Agreement, dated as of the date hereof and executed simultaneously herewith, between Varitek Industries, Inc., a Texas corporation (“Varitek”), and Cislunar Networks Corp., a Delaware corporation (“Cislunar”) (the “Loan Agreement”) pursuant to which Varitek shall make a term loan to Cislunar in the aggregate amount of $389,674.62 (the “Loan”) in response to Cislunar’s need for immediate financial assistance.

Option to Acquire Assets

During the course of Varitek’s discussions with Cislunar concerning Cislunar’s financial difficulties, the parties hereto discussed the possibility of Varitek acquiring all of the assets of Cislunar, including, without limitation, the assets set forth on Appendix A attached hereto (collectively, the “Assets”). As further consideration for Varitek entering into the Loan Agreement and the agreements, instruments and documents related thereto, Cislunar hereby grants to Varitek the exclusive option (the “Option”) to acquire the Assets within six (6) months from the date hereof (the “Option Period”) for a purchase price equal to (x) $389,674.62 less (y) all amounts outstanding on the Loan (including principal and interest) at the time of such acquisition (the “Outstanding Loan Amount”). In the event Varitek exercises the Option, such acquisition shall constitute full payment and satisfaction of the Outstanding Loan Amount.

Due Diligence

The parties hereto agree that Varitek and its agents and representatives shall be given access to the books and records and employees of Cislunar as provided herein from the date hereof through the end of the Option Period to allow Varitek to determine the viability and advisability of exercising the Option. Cislunar shall (a) give Varitek and Varitek’s counsel, accountants, engineers, agents and other representatives, including environmental consultants, reasonable access during normal business hours to the Assets, Cislunar’s employees and Cislunar’s books and records, in order that Varitek may have full opportunity to make, at

The rights of Varitek pursuant to this letter agreement shall not be exercised in such a manner as to interfere unreasonably with the business or operations of Cislunar.

Please indicate your acceptance of this letter agreement by signing the enclosed copy of this letter agreement and returning it to us. By so doing, you will be deemed to have agreed as follows:

A. You shall be bound by terms of the letter agreement; and

B. You will provide sufficient information, complete and correct in all material respects and in form and substance reasonably acceptable to Varitek, reasonably requested by Varitek in connection with its due diligence investigation of Cislunar.

This letter agreement may be executed in one or more counterparts, each of which shall be deemed an original and all of which together shall constitute one and the same instrument.

Very truly yours,
