From and after the termination of the voting rights set forth in this Section 1, the Board shall be elected by the holders of a majority of the shares of Common Stock owned by the Owners, to the extent applicable, at the time of such determination.

     Section 2. Transfer Provisions.

     (a) General Rights. In addition to any restrictions on the Transfer of Owner Shares that are imposed under applicable securities laws, no Owner shall Transfer or Pledge (as defined in Section 3 below) all or any part of his Owner Shares without the prior written consent of Yorktown and the holders of a majority of the shares of Common Stock then outstanding, unless in accordance with this Section 2.

     (b) Right of First Refusal and Tag-Along Right. No Owner shall have the right to effect any Transfer of his/its Owner Shares (other than as provided in subsection (c) of this Section 2) unless the Owner proposing to Transfer such Owner Shares (the “Selling Owner”) provides written notice to the other Owners (a “Transfer Notice”) of such desire, identifying the number of such Selling Owner’s Owner Shares that the Selling Owner proposes to Transfer (the “Disposition Shares”) together with the Offered Price (as defined below), and such Selling Owner complies with the Right of First Refusal of clause (i) and the Tag-Along requirements of clause (ii) below.

          (i) Right of First Refusal. The Company shall have a right of first refusal (the “Company’s Right of First Refusal”) to purchase all or any portion of the Disposition Shares, if the Company gives written notice of the exercise of such right to the Selling Owner within 20 days (the “Company’s Refusal Period”) from the receipt of the Transfer Notice. If the Company does not intend to exercise the Company’s Right of First Refusal in full or if the Company is not lawfully able to repurchase all of the Disposition Shares, the Company will send written notice thereof (the “Company’s Expiration Notice”) to the Selling Owner and to each other Owner at least 10 days before the expiration of the Company’s Refusal Period. If the Company does not purchase all of the Disposition Shares pursuant to the Company’s Right of First Refusal, the non-selling Owners (the “Non-Selling Owners”) shall have a right of second refusal (the “Owners’ Right of Second Refusal”) to purchase the remaining Disposition Shares (the “Remaining Disposition Shares”) by giving written notice of the exercise of such right to the Selling Owner and the Company within 20 days from receipt of the Company’s Expiration Notice. Each Non-Selling Owner shall have the right to purchase such Owner’s Proportionate Share (based upon the group of Non-Selling Owners) of the Remaining Disposition Shares. If any Non-Selling Owner elects not to purchase his or its Proportionate Share of the Remaining Disposition Shares, the other Non-Selling Owners may purchase their respective Proportionate Share (based on the group of the other Non-Selling Owners) of such Remaining Disposition Shares, and so on for any unpurchased Remaining Disposition Shares, until no Non-Selling Owner desires to purchase any more Remaining Disposition Shares. The purchase price for the Disposition Shares to be purchased by the Company upon exercise of the Company’s Right of First Refusal or the Non-Selling Owners upon exercise of the Owners’ Right of Second Refusal will be the bona fide cash price (or the fair market value of any non-cash consideration as determined in good faith by the Board) per share for which the Selling Owner proposes to transfer such Disposition Shares to the Proposed Purchaser(s) (as defined below) (the “Offered Price”) (subject to any rights the Company may have under any other agreement to purchase all or some of such Disposition Shares at a lower price), and will be payable within 30 days after the date of the Company’s Expiration Notice. Payment of the purchase price will be made, at the option of the Company, or each of the Non-Selling Owners, as applicable, (a) in cash (by cashier’s check), (b) by wire transfer of immediately available funds to the Selling Owner, or (c) by any combination of the foregoing.

          (ii) Tag-Along Rights. If the Company and the non-Selling Owners do not exercise their respective refusal rights to purchase all of the Disposition Shares, the Selling Owner shall cause the Person (as defined in Section 3 below) or group that proposes to acquire the Disposition Shares remaining after the exercise of such rights (the “Proposed Purchaser”) to offer in writing (the “Purchase Offer”) to the other Owners (each recipient is referred to as a “Tag-Along Owner”) to purchase a Proportionate Share (as defined in Section 3 below) of the remaining balance of such Shares. Any such purchase shall be made in accordance with the following:

               (A) the purchase from each Tag-Along Owner shall be made at the highest price per share and on such other terms and conditions as the Proposed Purchaser has offered to purchase Disposition Shares from the Selling Owner;

               (B) each Tag-Along Owner shall have no more than 20 days from the receipt of the Purchase Offer in which to accept such Purchase Offer, in whole or in part;

               (C) to the extent that a Tag-Along Owner accepts such Purchase Offer, the number of Owner Shares to be sold to the Proposed Purchaser by the Selling Owner shall be reduced; and

               (D) the closing of such purchase shall occur within 30 days after such acceptance or at such other time as the Selling Owner, the accepting Tag-Along Owners and the Proposed Purchaser may agree.

     (c) Excluded Affiliate Transfers. The provisions of this Section 2 do not apply to any Transfer by an Owner of his Owner Shares in an Excluded Affiliate Transfer (as defined in Section 3 below).

     (d) Termination. This Section 2 shall terminate upon the earlier of any one or more of the following: (i) the first date on which the Owners collectively do not own at least 50% of the equity interests in the Company or in any successor or assignee resulting from the consolidation, merger or sale of all or substantially all of the assets of the Company; (ii) the adjudication of the Company as a bankrupt, the execution by the Company of an assignment for the benefit of creditors or the appointment of a receiver of the Company; (iii) the voluntary or involuntary dissolution of the Company; (iv) when there is otherwise only one surviving Owner as a party to this Agreement; (v) the date on which the Company completes the initial sale of its shares of Common Stock to the public by filing a registration statement on Form S-1 or such other form under the 1933 Act, as amended; or (vi) the tenth (10^th) anniversary of the date hereof. The Company and the Owners each covenant and agree to enter into, and to use their commercially reasonable efforts to cause any successor or assignee of the Company described in clause (i) of this subsection to enter into, an agreement substantially similar to this Agreement if the Owners collectively own at least 50% of the equity interests in such successor or assignee.

     (e) Compliance with Securities Laws. Anything in this Agreement to the contrary notwithstanding, no Transfer or Pledge of capital stock of the Company otherwise permitted or required by this Agreement shall be made unless such Transfer or Pledge is in compliance with federal and state securities laws, including without limitation the 1933 Act and the rules and

regulations thereunder. If any such Transfer or Pledge is made pursuant to an exemption from such laws, rules and regulations, such Transfer or Pledge shall be made only upon the stockholder first having delivered to the Company a favorable written opinion of counsel, reasonably satisfactory in form and substance to the Company, to the effect that the proposed sale or transfer is exempt from registration under the 1933 Act and any applicable state securities laws; provided, however, that no such opinion of counsel shall be required for (i) an Excluded Affiliate Transfer by a stockholder if, in each case, the transferee agrees in writing to be subject to the terms and conditions hereof to the same extent as if such transferee were an original stockholder hereunder, or (ii) a sale duly made in compliance with Rule 144 promulgated under the 1933 Act, or any successor or analogous rule to Rule 144, or if the stockholder would be permitted to transfer the securities pursuant to paragraph (k) of Rule 144 (it being agreed that the Company shall have the right to receive evidence satisfactory to it regarding compliance with such rule or any successor or analogous rule prior to the registration of any such transfer), or (iii) a Transfer or Pledge pursuant to an effective registration statement.

Section 6. Right of First Offer on Subsequent Issuances.

     (a) General. Each Owner owning 10,000 or more shares of Common Stock or Preferred Stock has the right to purchase up to such Owner’s Pro Rata Share (as defined below) of any “New Securities” (as defined in Section 6(b)) that the Company may from time to time issue after the date of this Agreement.

     (b) New Securities. “New Securities” shall mean any Common Stock or Preferred Stock of the Company, whether now authorized or not, and rights, options or warrants to purchase such Common Stock or Preferred Stock, and securities of any type whatsoever that are, or may become, convertible or exchangeable into such Common Stock or Preferred Stock; provided, however, that the term “New Securities” does not include:

     (i) the issuance of any Common Stock, Preferred Stock or other forms of equity compensation to Employees approved by the Board;

     (ii) Company Securities issued as consideration to the sellers in connection with an acquisition by the Company in a bona fide arms length transaction, the terms of which have been approved by the Board;

     (iii) Company Securities issued in connection with any issuance of debt by the Company, the terms of which have been approved by the Board;

     (iv) Company Securities issued upon the exercise or conversion of any Company Securities issued in compliance with this Section 6;

     (v) Company Securities offered to the public pursuant to a registration statement filed under the 1933 Act, including without limitation pursuant to a Qualified Public Offering; and

     (vi) Company Securities issued as a dividend or upon any split or other pro-rata subdivision or combination of the Company Securities.

     (c) Procedures. In the event that the Company proposes to undertake an issuance of New Securities, it shall give to each Owner written notice of its intention to issue New Securities (the “Rights Notice”), describing the type of New Securities and the price and the general terms upon which the Company proposes to issue such New Securities. Each Owner shall have 15 days from the date of receipt of any such Rights Notice to agree in writing to purchase up to such Owner’s Pro Rata Share of such New Securities in cash for the price and upon the general terms specified in the Rights Notice by giving written notice to the Company and stating therein the quantity of New Securities to be purchased (not to exceed such Owner’s Pro Rata Share). If any Owner fails to so agree in writing within such 15-day period to purchase such Owner’s full Pro Rata Share of an offering of New Securities (a “Nonpurchasing Holder”), then such Nonpurchasing Holder shall forfeit the right hereunder to purchase that part of his Pro Rata Share of such New Securities that he did not so agree to purchase and the Company shall promptly give each Owner who has timely agreed to purchase his full Pro Rata Share of such offering of New Securities (a “Purchasing Holder”) written notice of the failure of any Nonpurchasing Holder to purchase such Nonpurchasing Holder’s full Pro Rata Share of such offering of New Securities (the “Overallotment Notice”). Each Purchasing Holder shall have a right of overallotment such that such Purchasing Holder may agree to purchase a portion of the Nonpurchasing Holders’ unpurchased Pro Rata Shares of such offering on a pro rata basis according to the relative Pro Rata Shares of the Purchasing Holders, at any time within 15 days after receiving the Overallotment Notice.

     (d) Failure to Exercise. In the event that the Owners fail to exercise in full the right of first offer within such 15 plus 15 day period, then the Company shall have 45 days thereafter to sell the New Securities with respect to which the Owners’ rights of first offer hereunder were not exercised, at a price and upon general terms not more favorable to the purchasers thereof than specified in the Company’s Rights Notice to the Owners. In the event that the Company has not issued and sold the New Securities within such 45 day period, then the Company shall not thereafter issue or sell any New Securities without again first offering such New Securities to the Owners pursuant to this Section 6.

     (e) Termination. This right of first offer under this Section 6 shall terminate upon (i) the date on which the Company completes the initial sale of its shares of Common Stock to the public by filing a registration statement on Form S-1 or such other form under the 1933 Act, as amended, (ii) the sale of all or substantially all the assets of the Company or (iii) an acquisition of the Company by another corporation or entity by sale of capital stock, consolidation, merger or other reorganization in which the holders of the Company’s outstanding voting stock immediately prior to such transaction own, immediately after such transaction, securities representing less than 50% of the voting power of the corporation or other entity surviving such transaction.

     (f) Waiver. Any provision of this Section 6 may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), upon the written consent of both (i) a majority in interest of the shares of Common Stock held by Owners and (ii) Yorktown. Any amendment or waiver effected in accordance with this Section 6(f) shall be binding upon each Owner and the Company.

     Section 7. Reports.

     (a) Within 45 days after the end of each fiscal quarter, the Management Owners shall furnish to each Owner a consolidated unaudited balance sheet of the Company and its Subsidiaries as of the end of such fiscal quarter and the related income statement, statement of stockholders equity and statement of cash flows for such fiscal quarter prepared in accordance with generally accepted accounting principles, consistently applied, except that footnotes and year-end adjusting entries shall not be required.

     (b) Within 120 days after the end of each fiscal year, the Management Owners shall furnish to each Owner a consolidated balance sheet of the Company and its Subsidiaries as of the end of such fiscal year and the related income statement, statement of stockholders equity and statement of cash flows for such fiscal year prepared in accordance with generally accepted accounting principles, consistently applied and as reviewed by (and together with the report of their review of) the Company’s auditors who shall be selected from among the nationally recognized accounting firms.

     (c) Within 30 days before the end of each fiscal year, the Board shall attempt to approve an Annual Budget for the succeeding year. On or prior to October 31 of each fiscal year, the President of the Company shall prepare and submit to the members of the Board a proposed Annual Budget for the next fiscal year. It is contemplated that the budget shall, as a separate line item, specify (without limitation) (i) each category of the general and administrative expenses of the Company, (ii) the compensation for each key employee of the Company, and (iii) the capital expenditures for the Company. As soon as practicable after any proposed Annual Budget is submitted to the Board, the Board shall approve or disapprove such Annual Budget. If the proposed Annual Budget is approved by the Board, then such proposed Annual Budget shall constitute the Company’s approved Annual Budget, subject to amendment from time to time. If the budget is not so approved, the members of the Board shall use their best efforts to resolve any questions with respect to revisions to the proposed Annual Budget. In the event that the Board is unable to reach an agreement with respect to an Annual Budget for a fiscal year prior to the commencement thereof, the Company shall continue to manage, maintain, supervise and direct its business in accordance with

the most recently approved budget until a new Annual Budget is approved by the Board.

     (d) Within 10 days after the occurrence of any material event, the Management Owners shall furnish notice of such event to the Owners together with a summary describing the nature of the event and its known or anticipated impact on the Company and its Subsidiaries.

     (e) The Company shall furnish such other information to the Owners as such Owners or their advisors may reasonably request concerning the financial condition of the Company.

     Section 8. Termination. This Agreement shall terminate upon the termination of Section 1, Section 2 and Section 6.

     Section 9. Miscellaneous.
