                NOW THEREFORE, each Shareholder agrees as follows:

1.             Lock Up.  Except as permitted in Section 2 below, for a period of 180 days from the first day that shares of GlobalSCAPE, Inc. common stock are first quoted on the OTCBB the Shareholders shall not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any shares of Common Stock or securities convertible into or exchangeable or exercisable for any shares of Common Stock, enter into a transaction which would have the same effect, or enter into swap, hedge or other arrangement that transfers, in whole or part, any of the economic consequences of ownership of the Common Stock, whether any such transaction is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement.

2.             Permitted Transfers.  Section 1 shall not apply to:

1

a)                the pledge by a Shareholder of shares of Common Stock to a financial institution in connection with a bona fide financing transaction, provided that the financial institution is subject to the terms of this Agreement;

b)               transfers of shares of Common Stock to immediate family members or trusts for the benefit of such family members, provided such transferee is subject to the terms of this Agreement;

c)                sales made as part of a “cashless exercise” of an option issued pursuant to the GlobalSCAPE, Inc. 1998 Stock Option Plan or the GlobalSCAPE, Inc. 2000 Stock Option Plan;

d)               transfers which would be exempt from the registration requirements of Section 5 of the Securities Act by virtue of the exemption provided by Section 4(2) of the Securities Act if the transferor were the issuer of common stock, provided that the transferee is subject to the terms of this Agreement; or

; provided, however, that no Shareholder may sell shares in a manner not permitted, or in an amount not permitted, by law, including the rules applicable to “affiliates” under SEC Rule 144, despite the availability of a permitted transfer under this Section 2.

3.             Stop Transfer Instructions.  Each Shareholder will agree to the entry of stop transfer instructions with the Company’s transfer agent against the transfer of the securities held by such Shareholder except in compliance with the foregoing restrictions.  Promptly upon execution of this Agreement, each shareholder who holds shares of Common Stock in the name of a brokerage firm or other representative shall cause the shares to be transferred into the name of the Shareholder.

4.             Headings.  Headings and captions are for convenience only and are not to be used in the interpretation of this Agreement.

8.             Severability.  If any provision of this Agreement shall be adjudged by any court of competent jurisdiction to be unenforceable or invalid, that provision shall be limited or

2

eliminated to the minimum extent necessary so that this Agreement shall otherwise remain in full force and effect and enforceable.

9.             Waiver.  No failure to exercise or delay in exercising any right under this Agreement will operate as a waiver of that right, nor will any single or partial exercise of any right or power preclude further exercise of that right or any other right.

11.          Null and Void.  If shares of Common Stock do not begin to be quoted on the OTCBB by March 15, 2002, this Agreement shall be null and void.

12.          Counterparts.  This Agreement may be signed in multiple counterparts, which together will be deemed an original.  This Agreement shall be binding upon any signing Shareholder notwithstanding the failure of any other Shareholder to sign.
