For purposes of this Section 3.5, such Transfer Notice shall constitute a "First Offer Notice," and the Restricted Securities subject to such ------------------- Transfer Notice shall comprise the "Offered Shares." -------------- (c) Within ten Washington, D.C. business days after the delivery of the First Offer Notice by the Section 3.5 Seller to each First Offeree, each First Offeree may, by notice in writing to the Company and the Section 3.5 Seller, elect to purchase all or any portion of the Offered Shares at the price and on the terms set forth in the First Offer Notice (the "First Offer Price"). ----------------- If the First Offerees in the aggregate elect to purchase more than the total number of Offered Shares then available for purchase, the right to purchase such Offered Shares shall be allocated to each such First Offeree first in proportion to (i) the record ownership of shares of Common Stock (including for purposes of this Section 3.5(c) all Common Stock issuable pursuant to the Series A Shares and the Warrants on an as-converted basis) of such First Offeree relative to (ii) the aggregate number of shares of Common Stock held of record by all First Offerees (including for purposes of this Section 3.5(c) all Common Stock issuable pursuant to the Series A Shares and the Warrants on an as-converted basis) and, in the event any Offered Shares are unallocated following the foregoing allocation, such unallocated Offered Shares shall be allocated to each such First Offeree in proportion to (x) the number of Offered Shares such First Offeree originally elected to purchase relative to (y) the aggregate number of Offered Shares all such First Offerees originally elected to purchase; provided, however, that in no event shall such allocation result in any First Offeree being required to purchase in the aggregate more Offered Shares than such First Offeree originally elected to purchase.

(e) In the event any Offered Shares remain unpurchased following the termination of the ten business day period referred to in Section 3.5(d) above, then the Section 3.5 Seller shall have 120 days following the termination of such ten business day period within which to consummate the sale of all of the remaining Offered Shares to a Third Party at a price per share in cash equal to or greater than the First Offer Price and on other terms no more favorable to the Purchaser than as set forth in the First Offer Notice. In the event the proposed purchase price of a Third Party for the remaining Offered Shares is less than the First Offer Price, the Section 3.5 Seller shall not Transfer any of such remaining Offered Shares at such lower price (the "Reoffer Price") ------------- unless the Section 3.5 Seller shall have first re-offered such remaining Offered Shares to each of the First Offerees by giving written notice (the "Reoffer ------- Notice") to each First Offeree advising such First Offeree of the Section 3.5 ------ Seller's intention to sell such remaining Offered Shares at the Reoffer Price.

If such sale to a Third Party is not consummated within such 120-day period (or, if later, within 30 days after such Reoffer Notice), <PAGE> such Section 3.5 Seller may not Tranfer any Restricted Securities for a period of 90 days pursuant to this Section 3.5, and thereafter only after complying with the provisions of this Section 3.5. No Transfer to a Third Party pursuant to this Section 3.5(e) shall be permitted (and any such Transfer shall be void and of no effect) unless and until such Third Party shall agree in writing, in form and substance satisfactory to the Company, to become bound, and becomes bound, by all the terms of this Agreement. 3.6. CLOSING; DELIVERIES. ------------------- (a) The closing of the purchase of any Offered Shares pursuant to Section 3.5 shall take place at the principal office of the Company on the tenth Washington, D.C. business day after the expiration of the last notice period applicable to such purchase. At such closing, each purchaser of Offered Shares shall deliver to the Section 3.5 Seller, against delivery of certificates representing the Offered Shares being acquired by such purchaser, a certified check or checks in an amount equal to the product of (i) the number of Offered Shares being purchased by such purchaser and (ii) the First Offer Price or the Reoffer Price, as the case may be. (b) Notwithstanding anything to the contrary contained in this Section 3.6, the Company shall not be obligated to purchase any Offered Shares it has elected to purchase under Section 3.5 hereof to the extent that the purchase thereof would violate any law or statute or any order, writ, injunction, decree, judgment, rule, regulation, policy or guideline promulgated, or judgment entered, by any federal, state, local or foreign court of governmental authority applicable to the Company or any of its subsidiaries. (c) In the event the Company is not obligated to purchase all or any portion of the Offered Shares it has elected to purchase under Section 3.5 above by reason of paragraph (b) above, the Company shall promptly deliver written notice to the Section 3.5 Seller which notice shall specify the number of Offered Shares that the Company is not obligated to purchase. For a period of 60 days following the receipt of such notice, the Section 3.5 Seller may sell such unpurchased Offered Shares to any other First Offeree approved by the Board of Directors upon the same terms and subject to the same conditions which would apply to a purchase of such Offered Shares by the Company. In the event the Section 3.5 Seller shall fail to consummate such a sale with respect to all such unpurchased Offered Shares within such 60-day period, the Company shall purchase such number of unpurchased Offered Shares that it is permitted to purchase under paragraph (b) above and the Company shall designate one or more Stockholders or Third Parties as the purchaser or purchasers of such remaining Offered Shares and, in the event the Company shall fail to designate such a purchaser or purchasers, the Section 3.5 Seller may sell any remaining unpurchased Offered Shares (i) to any Stockholder or (ii) to a Third Party without complying with the provisions of Section 3.5 above. No such Transfer shall be permitted (and any such Transfer shall be void and of no effect) unless and until (i) the requirements of Section 3.3 are satisfied and (ii) if such Transfer is to a Third Party, such Third Party shall agree in writing, in form and substance satisfactory to the Company, to become bound, and becomes bound, by all the terms of the Agreement. 3.7 PROHIBITED TRANSFERS. Notwithstanding any other provision of this -------------------- Section 3, no Stockholder shall Transfer any Restricted Securities in a Transfer subject to this Section 3 either <PAGE> (a) to any person that is a direct or indirect competitor of the Company without the prior written consent of the Company, which may be granted or withheld in the absolute discretion of the Company or (b) for a period of three years from the date of this Agreement, except pursuant to a Permitted Transfer. 3.8 TERMINATION OF SECTION 3 PROVISIONS.

In case the Company shall receive from ------------------------ Initiating Holders a written request that the Company effect any registration, qualification or compliance with respect to not less than that number of shares of Registrable Securities which would result in an anticipated aggregate offering price, net of underwriting discounts and commissions, greater than $2,000,000, the Company will: <PAGE> (i) promptly give written notice of the proposed registration, qualification or compliance to all other Holders; and (ii) as soon as practicable, use its commercially reasonable efforts to effect such registration, qualification or compliance (including, without limitation, appropriate qualification under applicable blue sky or other state securities laws and appropriate compliance with applicable regulations issued under the Securities Act and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request received by the Company within 20 days after receipt of such written notice from the Company; Provided, however, that the Company shall not be obligated to take any action to effect any such registration, qualification or compliance pursuant to this Section 5.1: (A) in any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, qualification or compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; (B) prior to six months after the effective date of the Company's first registered public offering of its Common Stock; (C) during the period starting with the date 60 days prior to the Company's estimated date of filing of, and ending on the date six months immediately following the effective date of, any registration statement pertaining to securities of the Company (other than a registration of securities in a Commission Rule 145 transaction or with respect to an employee benefit plan), provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective; (D) after the Company has effected three such registrations pursuant to this Section 5.1(a), and such registrations have been declared or ordered effective; or (E) if the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors it would be seriously detrimental to the Company or its stockholders for a registration statement to be filed in the near future (in which case the Company's obligation to use its best efforts to register, qualify or comply under this Section 5.1 shall be deferred for a period not to exceed 120 days from the date of receipt of written request from the Initiating Holders; provided, however, that the Company may not exercise this deferral right more than once per 12-month period). (b) Underwriting. In the event that a registration pursuant to this ------------ Section 5.1 is for a registered public offering involving an underwriting, the Company shall so advise the Holders as part of the notice given pursuant to Section 5.1(a)(i). In such event, the <PAGE> right of any Holder to registration pursuant to Section 5.1(b) shall be conditioned upon such Holder's participation in the underwriting arrangements required by this Section 5.1, and the inclusion of such Holder's Registrable Securities in the underwriting to the extent requested shall be limited to the extent provided herein. The Company shall (together with all Holders proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by a majority in interest of the Initiating Holders, but subject to the Company's reasonable approval. Notwithstanding any other provision of this Section 5.1, if the managing underwriter advises the Initiating Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise all holders of Registrable Securities and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among all Holders in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by such Holders at the time of filing the registration statement. No Registrable Securities excluded from the underwriting by reason of the underwriter's marketing limitation shall be included in such registration. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest 100 shares. Prior to excluding any Registrable Securities from any underwriting pursuant to this paragraph, the Company shall exclude from such underwriting all securities that are not Registrable Securities. If any Holder of Registrable Securities disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company, the managing underwriter and the Initiating Holders. The Registrable Securities and/or other securities so withdrawn shall also be withdrawn from registration, and such Registrable Securities shall not be transferred in a public distribution prior to 180 days after the effective date of such registration, or such other shorter period of time as the underwriters may require. 5.2 COMPANY REGISTRATION. -------------------- (a) Notice of Registration.

If the registration of which the Company gives ------------ notice is for a registered public offering involving an underwriting, the Company shall so advise the Holders <PAGE> as a part of the written notice given pursuant to Section 5.2(a)(i).

All Piggyback Holders proposing to distribute their securities through such underwriting shall (together with the Company and the other holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by the Company. Notwithstanding any other provision of this Section 5.2, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the managing underwriter and the Company may reduce the Registrable Securities to be included in such registration to the extent the underwriters deem necessary; provided, however, that any Registrable Securities held by the Piggyback Holders proposed to be included in the registration and underwriting shall be reduced to zero prior to any reductions with respect to Registrable Securities held by any other Holders. The Company shall so advise all Holders and other holders distributing their securities through such underwriting and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among all the Holders in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by such Holder at the time of filing the Registration Statement. To facilitate the allocation of shares in accordance with the above provisions, the Company may round the number of shares allocated to any Holder or holder to the nearest 100 shares. If any Holder disapproves of the terms of any such underwriting, he may elect to withdraw therefrom by written notice to the Company and the managing underwriter.
