3. TRANSFER OF STOCK.

(a) Resale of Securities. No Investor shall Transfer any Units other than in accordance with the provisions of this Section 3 and in accordance with the provisions of the Operating Agreement. Any Transfer or purported Transfer made in violation of this Section 3 or the Operating Agreement shall be null and void and of no effect.

(b) Rights of First Refusal.

(i) Limitations on Transfer. Neither Spencer, Buckman, the Management Investors nor the Additional Investors shall Transfer any of the Units Owned by them unless Spencer, Buckman, the Management Investors or the Additional Investors, as the case may be, desiring to make the Transfer (hereinafter referred to as the "Transferor") shall have first made an offer to sell to the Company and then to the Institutional Investors as contemplated by this Section 3(b), and such offers shall not have been accepted.

(ii) Offer by Transferor. Copies of the Transferor's offer shall be given to the Company and the Institutional Investors and shall consist of an offer to sell to the Company or, failing its

election to purchase, then to the Institutional Investors, all of the Units then proposed to be Transferred by the Transferor (the "Subject Units") pursuant to a bona fide offer of a third party, to which copies shall be attached a statement of intention to Transfer to such third party, the name and address of the prospective third party transferee, the number of Subject Units involved in the proposed Transfer, and the terms of such Transfer.

(iii) Acceptance of Offer.

(A) Within twenty (20) days after the receipt of the offer described in Section 3(b)(ii) (such 20-day period, the "Company Option Period"), the Company may, at its option, elect to purchase all, but not less than all, of the Subject Units. The Company shall give notice of its intention to exercise, or that it does not intend to exercise, its option hereunder, to the Transferor and to each Institutional Investor within the Company Option Period. Failure by the Company to give notice of its intention to exercise its option hereunder within the Company Option Period shall be deemed an election not to exercise such option.

(B) In the event that the Company does not exercise its option to purchase all of the Subject Units within the Company Option Period or the Company revokes its election to purchase the Subject Units in accordance with Section 3(b)(v), the Transferor shall deliver to the Institutional Investors a written notice to the effect that the Company did not exercise its option to purchase or that the Company revoked its election to purchase all of the Subject Units, as the case may be. In such event, the Institutional Investors may purchase all, but not less than all, of the remaining Subject Units by giving written notice thereof to the Transferor and to the Company within twenty (20) days after receipt of written notice from the Transferor described in the immediately preceding sentence (such 20-day period, the "Institutional Investor Option Period"). Any Institutional Investor that fails to give such notice to the Transferor and to the Company within such Institutional Investor Option Period shall be deemed to have waived its rights under this Section 3(b) with respect to the proposed Transfer. The Institutional Investors shall purchase the Subject Units pro rata among themselves (based on the number of Units then Owned by each Institutional Investor calculated as of the date of commencement of the Institutional Investor Option Period) or as they shall otherwise agree upon among themselves.

(C) In either event, the notice required to be given by the purchasing party (the "Purchaser") shall specify a date for the closing of the purchase which shall not be more than thirty (30) days after the date of the giving of such notice.

(iv) Purchase Price. The purchase price per share for the Subject Units shall be the price per share offered to be paid by the prospective transferee described in the offer, which price shall be paid in cash or, if so provided in the offer of the prospective transferee, cash plus deferred payments of cash in the same proportions, and with the same terms of deferred payment as therein set forth.

(v) Consideration Other Than Cash. If the offer of the Subject Units under this Section 3(b) is for consideration other than cash or cash plus deferred payments of cash, then the Purchaser shall pay the cash equivalent of such other consideration. If the Transferor and the Purchaser cannot agree on the amount of such cash equivalent within ten (10) days after the beginning of the Company Option Period or the Institutional Investor Option Period, as the case may be, any of such parties may, by three (3) days' written notice to the other, initiate appraisal proceedings under Section 3(b)(vi) for determination of the cash equivalent. The Company Option Period and the Institutional Investor Option Period, as applicable, shall automatically be extended during the period in which an appraisal is conducted pursuant to Section 3(b)(vi) below. The Purchaser may give written notice to the Transferor revoking an election to purchase the Subject Units within ten (10) days after determination of the appraised value, if it chooses not to purchase the Subject

Units. An appraisal conducted during the Company Option Period shall not be binding on the Institutional Investors and such Institutional Investors shall have the right (which shall be determined by the approval of the electing Institutional Investors holding a majority of the Common Units Owned by such electing Institutional Investors), but not the obligation, to conduct a separate appraisal in the event the Company revokes its election to purchase the Subject Units after determination of the appraised value.

(vi) Appraisal Procedure. If any party shall initiate an appraisal procedure to determine the amount of the cash equivalent of any consideration for the Subject Units under Section 3(b)(v), then the Transferor, on the one hand, and the Purchaser, on the other hand, shall each promptly appoint as an appraiser an individual who shall be a member of a nationally-recognized investment banking firm. Each appraiser shall, within thirty (30) days of appointment, separately investigate the value of the consideration for the Subject Units as of the proposed Transfer date and shall submit a notice of an appraisal of that value to each party. Each appraiser shall be instructed to determine such value without regard to income tax consequences to the Transferor as a result of receiving cash rather than other consideration. If the appraised values of such consideration (the "Earlier Appraisals") vary by less than ten percent (10%) measured from the lower appraisal, the average of the two appraisals on a per share basis shall be controlling as the amount of the cash equivalent. If the appraised values vary by more than ten percent (10%), measured from the lower appraisal, the appraisers, within ten (10) days of the submission of the last appraisal, shall appoint a third appraiser who shall be a member of a nationally recognized investment banking firm. The third appraiser shall, within thirty (30) days of his appointment, appraise the value of the consideration for the Subject Units (without regard to the income tax consequences to the Transferor as a result of receiving cash rather than other consideration) as of the proposed Transfer date and submit notice of his appraisal to each party. The value determined by the third appraiser shall be controlling as to the amount of the cash equivalent unless the value is greater than the two Earlier Appraisals, in which case the higher of the two Earlier Appraisals will control, and unless that value is lower than the two Earlier Appraisals, in which case the lower of the two Earlier Appraisals will control. If any party fails to appoint an appraiser or if one of the two initial appraisers fails after appointment to submit his appraisal within the required period, the appraisal submitted by the remaining appraiser shall be controlling. The Transferor and the Purchaser shall each bear the cost of its respective appointed appraiser. The cost of the third appraisal shall be shared one-half by the Transferor and one-half by the Purchaser.

(vii) Closing of Purchase. The closing of the purchase shall take place at the office of the Company or such other location as shall be mutually agreeable and the purchase price, to the extent comprised of cash, shall be paid at the closing, and cash equivalents and documents evidencing any deferred payments of cash permitted pursuant to Section 3(b)(iv) above shall be delivered at the closing. At the closing, the Transferor shall deliver to the Purchaser the certificates evidencing the Subject Units, if any, to be conveyed, free and clear of any and all liens and encumbrances, duly endorsed and in negotiable form with all the requisite documentary stamps affixed thereto.

(viii) Release from Restriction; Termination of Rights. If the offer to sell is neither accepted by the Company nor fully accepted by the Institutional Investors, the Transferor may make a bona fide Transfer to the prospective transferee named in the statement attached to the offer in accordance with the agreed upon terms of such Transfer, provided that (A) such Transfer shall be made only in strict accordance with the terms set forth in the written notice delivered to the Company and the Institutional Investors pursuant to Section 3(b)(ii) hereof and (B) the transferee agrees, in writing (by executing a Joinder Agreement), to be bound by the provisions of this Agreement and the Operating Agreement in the same manner as the Transferor. If the Transferor shall fail to make such Transfer within sixty (60) days following the expiration of the Company

Option Period or the Institutional Investor Option Period, as applicable, or, in the event the Institutional Investors revoke their election to purchase the Subject Units pursuant to Section 3(b)(v), within sixty (60) days of the date of such notice of revocation, such Subject Units shall again become subject to all the restrictions of this Section 3.

(ix) Limitations. The provisions of this Section 3(b) shall not apply to (i) sales by Tag-Along Investors (as defined below) pursuant to Section 3(c) hereof, or (ii) sales by Investors pursuant to Section 3(d) hereof (Drag-Along Rights) or (iii) Transfers to Permitted Transferees or to the Company.

(x) Operating Agreement Obligations. A Transfer pursuant to this Section 3(b) shall not be valid unless the transferee delivers to the Company an executed copy of the Joinder Agreement.

(i) In the event that the Investors Owning a majority of the Units (the "Majority Holders") intend to Transfer all of their Units (other than Transfers to any Permitted Transferee or to the Company) in a single transaction or a series of related transactions (the "Selling Investors"), such Selling Investors' shall notify the other Investors (the "Tag-Along Investors"), in writing, of such proposed Transfer and its terms and conditions. Within ten (10) business days of the date of such notice, each other Tag-Along Investor shall notify the Selling Investors if it elects to participate in such Transfer. Any Tag-Along Investor that fails to notify the Selling Investors within such ten (10) business day period shall be deemed to have waived its rights under this Section 3(c) with respect to the proposed Transfer. Each Tag-Along Investor that so notifies the Selling Investors shall have the right to sell, at the same price and on the same terms and conditions as the Selling Investors, an amount of Units equal to the Units the third party actually proposes to purchase multiplied by a fraction, the numerator of which shall be the number of Units Owned by such Tag-Along Investor and the denominator of which shall be the aggregate number of Units Owned by the Selling Holders and each Tag-Along Investor exercising its rights under this Section 3(c). Notwithstanding the foregoing, in the event the Selling Investor is selling only Preferred Units, holders of the Common Units shall not have the right to sell Common Units pursuant to this Section 3(c).

(ii) Notwithstanding anything contained in this Section 3(c), in the event that all or a portion of the purchase price consists of securities and the sale of such securities to the Tag-Along Investors would require either a registration under the Securities Act or the preparation of a disclosure document pursuant to Regulation D under the Securities Act or a similar provision of any state securities law, then, at the option of the Selling Investor, any one or more of the Tag-Along Investors may receive, in lieu of such securities, the fair market value of such securities in cash, as determined in good faith by the Board.

(d) Drag Along Right.

(i) If at any time and from time to time after the date of this Agreement, the Majority Holders wish to (i) Transfer in a bona fide arms' length sale all of their Units to any Person or Persons who are not Affiliates of the Company or any of the Majority Holders or (ii) approve any merger of the Company with or into any other Person who is not an Affiliate of the Company or the Majority Holders, or (iii) approve any sale of all or substantially all of the Company's assets to any Person or Persons who are not Affiliates of the Company or any of the Majority Holders (for purposes of this Section 3(d), such Person or Persons shall be referred to as the "Proposed Transferee"), the Majority Holders shall have the right (for purposes of Section 3(d), the "Drag-Along Right") to (x) in the case of a Transfer of the type referred to in clause (i), require each Investor to sell to the Proposed Transferee all Units (including any warrants or options to acquire Units) then Owned by such Investor for the same per Unit consideration as proposed to be received by the Majority Holders (less, in the case of options or warrants, the exercise price for

such options or warrants), or (y) in the case of a merger or sale of assets referred to in clauses (ii) or (iii) above, require each other Investor to vote all Units then Owned by such other Investor in favor of such transaction. Each Investor agrees to take all steps necessary to enable him or it to comply with the provisions of this Section 3(d) to facilitate the Majority Holder's exercise of a Drag-Along Right.

(ii) To exercise a Drag-Along Right, the Majority Holders shall give each Investor a written notice (for purposes of this Section 3(d), a "Drag-AIong Notice") containing (1) the name and address of the Proposed Transferee and (2) the proposed purchase price, terms of payment and other material terms and conditions of the Proposed Transferee's offer. Each Investor shall thereafter be obligated to sell its Units (including any warrants or options Owned by such Investor) to the Proposed Transferee or vote its Units in favor of the proposed transaction, as the case may be; provided that the sale to the Proposed Transferee or the merger or sale of assets, as applicable, is consummated within ninety (90) days of delivery of the Drag-Along Notice. If the sale to the Proposed Transferee or the merger or asset sale is not consummated within such 90-day period, then each Investor shall no longer be obligated to sell such Investor's Units or vote (or, having voted such Units in favor of such merger or sale of assets, such Investor may revoke such vote) for such merger or assets sale pursuant to that specific Drag-Along Right but shall remain subject to the provisions of this Section 3(d).

(iii) Notwithstanding anything contained in this Section 3(d), in the event that all or a portion of the purchase price consists of securities and the sale of such securities to the Investors would require either a registration under the Securities Act or the preparation of a disclosure document pursuant to Regulation D under the Securities Act or a similar provision of any state securities law, then, at the option of the Majority Holders, the Investors may receive, in lieu of such securities, the fair market value of such securities in cash, as determined in good faith by the Board.
