Inc., a Virginia corporation (the "Company").

                                    RECITALS

         A.   Concurrently with the execution of this Agreement, Precision
Funding, LLC ("Precision Funding"), Arthur C. Kellar ("Kellar"), Desarollo and
the Company are entering into an Exchange Agreement (the "Exchange Agreement")
that provides, among other things, for the contribution of certain debentures
held by Precision Funding and Kellar in exchange for the issuance by the Company
of certain equity consideration consisting of common stock, preferred stock and
warrants (the "Exchange Equity Consideration").

         B.   The Company's Articles of Incorporation currently do not provide
for a sufficient number of authorized but unissued shares of capital stock to
issue the common stock and common stock issuable upon exercise of the warrants
comprising the Exchange Equity Consideration.

         C.   Pursuant to the Exchange Agreement, the Company has agreed to
submit to its shareholders at its 2002 Annual Meeting of Shareholders (the
"Meeting") a proposal (the "Proposal") to amend the Company's Articles of
Incorporation to increase the number of its authorized but unissued shares of
capital stock from 20,000,000 to 40,000,000, including 39,000,000 shares of
common stock and 1,000,000 shares of preferred stock.

         D.   The Shareholders are or will become as of the date hereof the
beneficial owners (as defined in Rule 13d-3 under the Securities Exchange Act of
1934, as amended (the "Exchange Act")) of the number of outstanding shares of
capital stock of the Company indicated on Annex 1 to this Agreement.

         E.   As a material inducement to enter into the Exchange Agreement,
Precision Funding, Desarollo, Kellar and the Company desire each of the
Shareholders to agree, and in consideration for good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, each of the
Shareholders is willing to agree, to vote the Shares and New Shares (each as
defined below) in favor of approval of the Proposal at the Meeting and at any
subsequent shareholders' meeting at which a similar proposal is submitted for
shareholder approval held within two years from the date hereof (a "Subsequent
Meeting").

              1.1  Agreement to Vote Shares. During the term of this Agreement,

              (a)  in favor of approval of the Proposal or any similar proposal,
including all actions contemplated thereby and all actions necessary or

              1.3  Definition. For purposes of this Agreement, "Shares" shall
mean all issued and outstanding shares of capital stock of the Company of which
a Shareholder is the beneficial owner or over which a Shareholder has voting
control, including any securities convertible into or exercisable or
exchangeable for shares of the Company's capital stock, all as set forth on
Annex 1 attached hereto.

              1.4  Additional Purchases. Each Shareholder agrees that any shares
of capital stock of the Company that such Shareholder purchases, or with respect
to which such Shareholder otherwise acquires beneficial ownership or voting
control after the execution of this Agreement and prior to the date of
termination of this Agreement ("New Shares"), shall be subject to the terms and
conditions of this Agreement to the same extent as if they constituted Shares.

              1.5  Transfer and Encumbrance. During the term of this Agreement,
each Shareholder agrees not to transfer, sell, exchange, pledge, gift, or
otherwise dispose of or encumber (collectively, "Transfer") record ownership or
beneficial ownership, or both, of any of the Shares or any New Shares or to
discuss, negotiate, or make any offer or agreement relating thereto; provided,
however, the foregoing restriction on Transfers shall not apply to any Shares or
New Shares owned or controlled by Kellar or Desarollo if the Proposal is not
approved by the Company's shareholders at the Meeting.
