Article II The Transferred Shares and the Repurchased Shares Section 2.01. Transferred Shares. At the Closing, BTG shall transfer to GTSI, at no cost to GTSI, the Transferred Shares, free and clear of all Liens, by delivering to GTSI certificates representing the Transferred Shares duly endorsed for transfer in blank or with assignment separate from certificates duly endorsed, with all necessary transfer tax stamps, if any, affixed or provided for. Section 2.02. Repurchased Shares. At the Closing, (a) BTG shall sell to GTSI, and GTSI shall purchase from BTG, the Repurchased Shares, free and clear of all Liens, by delivering to GTSI certificates representing the Repurchased Shares duly endorsed for transfer in blank or with assignment separate from certificates duly endorsed, with all necessary transfer tax stamps, if any, affixed or provided for, and (b) in payment therefor, GTSI shall deliver the GTSI Note to BTG. Article III The Optioned Shares Section 3.01. Repurchase Option. (a) BTG hereby grants to GTSI the exclusive option (the "Repurchase Option") to purchase all or any part of the Optioned Shares for a per share price (the "Option Price") of $5.25 at any time or from time to time until the fifth anniversary of the Closing (the "Option Period") by delivery of written notice to BTG specifying the number of Optioned Shares being purchased and the date, no more than 10 days after such notice, on which payment therefor will be made. The closing on the purchase and sale of such Optioned Shares shall be held at GTSI's principal office on the date specified in such notice. At such closing, certificates representing the Optioned Shares to be sold shall be delivered to GTSI, duly endorsed for transfer in blank or with assignment separate from certificates duly endorsed, with all necessary transfer tax stamps, if any, affixed or provided for, against delivery of payment in immediately available funds or a promissory note, as provided below, of an amount equal to the product of the number of Optioned Shares being purchased and the Option Price. All Optioned Shares purchased pursuant to the Repurchase Option shall be delivered by BTG to GTSI free and clear of all Liens. Payment by GTSI upon exercise of the Repurchase Option shall be in immediately available funds unless notice of exercise of the Repurchase Option is delivered to BTG on or before December 31, 1999, in which case payment in connection with such notice may be made, in GTSI's discretion, either in immediately available funds or by the delivery of a promissory note substantially in the form of Exhibit 2 hereto, the terms of which (depending on the number of Optioned Shares purchased) shall be as set forth on Exhibit 3 hereto. (b) If after the Closing the number of shares of Common Stock represented by the original number of Optioned Shares is increased or decreased as a result of any increase or decrease in the number of issued shares of Common Stock resulting from the declaration of a dividend or the making of a distribution on the outstanding Common Stock, the subdivision or reclassification of the outstanding Common Stock into a greater number of shares or the combination or reclassification of the outstanding Common Stock into a smaller number of shares, the Option Price shall be adjusted by multiplying the Option Price in effect immediately prior to such adjustment by a fraction, the numerator of which shall be the number of Optioned Shares issuable upon the exercise of the Repurchase Option immediately prior to such adjustment, and the denominator of which shall be the number of Optioned Shares issuable upon the exercise of the Repurchase Option immediately thereafter. (c) The parties agree that, effective as of the Closing, Section 2.02 of the Standstill Agreement shall be amended to delete clauses (b) and (d) therefrom, so that transfers described therein will thereafter require the prior written consent of GTSI duly authorized by a majority of the members of the GTSI Board. (d) BTG agrees to provide written notification to GTSI of BTG's bona fide intention to dispose of or otherwise transfer any GTSI Shares pursuant to Section 2.02(c) of the Standstill Agreement no less than 10 business days prior to the intended disposition or transfer. GTSI shall have the absolute right, but not the obligation, in its sole discretion to exercise the Repurchase Option at any time prior to the date of such intended disposition with respect to any Repurchase Shares covered by such notification. (e) BTG agrees that it shall be a condition to any permitted Transfer (as defined in the Standstill Agreement) under Section 2.02(a) or (e) of the Standstill Agreement that the transferee agree in writing to be bound by the terms of the Repurchase Option. (f) Subject to the terms and conditions of this Section 2.02(f), the parties agree that BTG may solicit a bona fide, third party buyer ("Prospective Buyer") for all or part of the Optioned Shares. If BTG delivers a written notice to GTSI identifying the Prospective Buyer, the number of Optioned Shares proposed to be purchased by the Prospective Buyer, and the proposed price, terms of sale and closing date, accompanied by a copy of the written offer (the "Offer") signed by the Prospective Buyer with respect to such proposed purchase, GTSI shall have the right, but not the obligation, in its sole discretion, and the Offer must so reflect, to exercise the Repurchase Option with respect to the Optioned Shares which are the subject of the Offer and immediately thereafter to sell such Optioned Shares to the Prospective Buyer on the same terms and conditions as are set forth in the Offer. Closing on the purchase of the Optioned Shares by GTSI shall be held in accordance with the provisions set forth in Section 3.01(a) and closing on the sale of such Optioned Shares to the Prospective Buyer shall be held at the same location immediately thereafter. If GTSI exercises the Repurchase Option and sells the Optioned Shares to the Prospective Buyer in accordance with this Section 3.01(f), the payment from BTG to GTSI under Section 3.02(a) shall not be required with respect to such transaction. GTSI agrees to consider in good faith any Offer properly delivered to it hereunder, subject to its absolute discretion to reject any such Offer. If GTSI rejects an Offer, BTG must retain the Optioned Shares in accordance with the terms of this Agreement. Section 3.02. Sale of Optioned Shares by BTG. (a) If BTG sells during the Option Period any of the Optioned Shares as permitted under the Standstill Agreement, BTG agrees as a condition to any such sale to pay to GTSI concurrently with or prior to such sale an amount in cash equal to the product of the number of Optioned Shares being sold and $0.50 (the "Per Share Price"). (b) If after the Closing the number of shares of Common Stock represented by the original number of Optioned Shares is increased or decreased as a result of any increase or decrease in the number of issued shares of Common Stock resulting from the declaration of a dividend or the making of a distribution on the outstanding Common Stock, the subdivision or reclassification of the outstanding Common Stock into a greater number of shares or the combination or reclassification of the outstanding Common Stock into a smaller number of shares, the Per Share Price shall be adjusted by multiplying the Per Share Price in effect immediately prior to such adjustment by a fraction, the numerator of which shall be the number of Optioned Shares issuable upon the exercise of the Repurchase Option immediately prior to such adjustment, and the denominator of which shall be the number of Optioned Shares issuable upon the exercise of the Repurchase Option immediately thereafter. Section 3.03. Stock Legend. On the date of the Closing, BTG shall cause the certificates evidencing the Optioned Shares to be tendered to GTSI's transfer agent, First Union National Bank, which shall issue to BTG stock certificates of the same denomination in exchange therefor bearing the following modified legends: "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER ANY APPLICABLE STATE SECURITIES LAW AND MAY NOT BE TRANSFERRED EXCEPT UPON DELIVERY TO THE CORPORATION OF AN OPINION OF COUNSEL SATISFACTORY IN FORM AND SUBSTANCE TO IT THAT SUCH TRANSFER WILL NOT VIOLATE THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE SECURITIES LAW.
