EXHIBIT 10.1 EXECUTION COPY VMC HOLDING CORPORATION STOCKHOLDERS' AGREEMENT This Agreement is executed as of the 28th day of April, 2005 (the "EFFECTIVE DATE"), by and among VMC Holding Corporation, a Delaware corporation (the "COMPANY"), Transportation Resource Partners, LP ("TRP"), United Auto Group, Inc. ("UAG"), Penske Truck Leasing Co., L.P. ("PTL"), and Opus Ventures General Partner Limited ("OPUS" and collectively with TRP, UAG and PTL, the "INITIAL INVESTORS," and each a "INITIAL INVESTOR") (each, together with any transferee of their respecting Shares that is permitted hereunder, a "STOCKHOLDER" and collectively, the "STOCKHOLDERS"). WHEREAS, the Company has 10,000 shares of authorized capital stock (these shares together with any other class or series of common or preferred stock that may be authorized, designated or issued by the Company from time to time, the "SHARES"); WHEREAS, the Shares currently consist of: 10,000 Shares of Common Stock (the "COMMON SHARES"), of which 5,000 are issued and outstanding; WHEREAS, the Stockholders are the collective holders of all issued and outstanding Shares; and WHEREAS, the Stockholders desire to provide for the ongoing management of the Company in accordance with the wishes of the Stockholders, for certain restrictions on the transfer of Shares, and otherwise to establish their relationship as Stockholders and their and the Company's rights and obligations with respect to the Shares. NOW, THEREFORE, in consideration of the mutual agreements contained herein and for other valuable consideration, and intending to be legally bound, the parties hereby agree as follows: ARTICLE 1. ELECTION OF DIRECTORS 1.1 COMPOSITION OF BOARD; VOTING AGREEMENT. Subject to the terms of this Agreement, the Board of Directors of the Company shall have four members. TRP shall have the right to designate two directors, UAG shall have the right to designate one director, and Laurence Vaughan shall have the right to serve as a director. Each of the Stockholders shall vote all Shares held by it (including any Shares that may be hereafter acquired and Shares, if any, in respect of which that Stockholder has been granted a proxy) at any meeting of the Stockholders of the Company called and held for that purpose, and shall sign any consent of Stockholders presented for that purpose, for the election as a director of the Company of each of the following persons: A. Each of the two persons designated by TRP; B. The person designated by UAG; and C. Laurence Vaughan, subject to the limitations set forth below. The right of each of TRP and UAG to designate one or more directors set forth above shall terminate at the time that the relevant Stockholder (together with its Controlled Affiliates as defined below) holds of record less than 10% of the issued and outstanding Common Shares and shall not thereafter be restored by any subsequent acquisition of Common Shares, except that (subject to the second succeeding paragraph below) if a Stockholder whose rights to nominate a director have lapsed, subsequently acquires all of the Common Shares held by another Stockholder having a right to nominate a director at the time of transfer, the transferee of such Shares shall acquire also that right. Subject to the next succeeding paragraph below, if the rights of any Stockholder to designate a director under this SECTION 1.1 cease, in accordance with the terms of these Sections, the director that that Stockholder had a right to designate shall be nominated by the Company's Board of Directors and elected by the affirmative vote of a majority of the then outstanding Common Shares voting as a single class. Any Stockholder that loses its right to appoint one or more directors pursuant to this SECTION 1.1, due to holding of record less than 10% of the issued and outstanding Common Shares, shall have the right to appoint one observer (without participation or voting rights of any kind) to all Board meetings as long as such Stockholder holds of record 5% of the issued and outstanding Common Shares, after which the right to appoint an observer shall cease. So long as PTL holds of record at least 5% of the issued and outstanding Common Shares it shall have the right to appoint one observer (without participation or voting rights of any kind) to all Board meetings. The rights of Laurence Vaughan to serve as a director pursuant to this SECTION 1.1 are personal to him. Thus, these rights do not transfer with any Transfer of Shares permitted hereunder held by Opus or that he may acquire, notwithstanding any other provision of this Agreement, and lapse upon the first to occur of (A) his death, (B) his disability, or (C) him (and his Controlled Affiliates, including Opus) ceasing to hold of record a majority of the Shares originally issued to Opus. If Laurence Vaughan's rights to serve as a director lapse as provided herein, the Board of Directors of the Company, except as otherwise permitted in SECTION 2.1B, shall consist of three directors, two of whom shall be designated by TRP pursuant to SECTION 1.1A and one of whom shall be designated by UAG pursuant to SECTION 1.1B. 1.2 TRANSFERABILITY. Any person's right to designate a director (or appoint an observer) under SECTION 1.1 may be transferred only in connection with a transfer of all of the Common Shares then held by the person having that right, except that Laurence Vaughan's right to serve as a director may not be transferred. 1.3 REMOVAL OF DIRECTORS. The directors designated (or observers appointed) pursuant to SECTION 1.1 may be removed with or without cause by, and only by, the affirmative vote of a majority of the Common Shares entitled to vote for their election, given either at a special meeting of the holders of such Shares duly called for that purpose, or by written consent of those holders in accordance with Delaware law. -2- ARTICLE 2. CERTAIN COMPANY ACTIONS REQUIRING SPECIAL APPROVAL; CERTAIN AGREEMENTS 2.1 SPECIAL APPROVAL RIGHTS. In addition to any requirements that may from time to time be imposed under the Company's Certificate of Incorporation or Bylaws or under applicable law, each of the following actions shall require special approval as set forth below: A. UAG. The following actions shall require the approval of the director nominated by UAG, and, if requested by that director, the approval of a majority of the then outstanding Common Shares now held by UAG, voting as a single class by written consent or at a special meeting called for that purpose in accordance with Delaware law: (i) Any material change to the Company's Certificate of Incorporation or Bylaws, without regard as to whether the change would otherwise require the approval of the Company's Stockholders; (ii) The declaration or payment by the Company of any dividend or distribution on its Common Shares other than a distribution payable solely in cash or Common Shares ratably to all holders of Common Shares; (iii) The redemption, acquisition, or purchase ("REPURCHASE") by the Company of any Shares of its capital stock or any options, warrants, or rights exercisable for or convertible into such Shares, other than redemptions, purchases, or acquisitions effected pursuant to the terms of issuance of such Shares or other securities or rights, and approved at the time of such issuance by UAG; (iv) Any acquisition of or investment in any person that in the reasonable business judgment of UAG competes, directly or indirectly, with the business of UAG as at the date of investment or acquisition or that could reasonably be expected to impair UAG's business relationships with original equipment manufacturers; (v) The guarantee by the Company of the obligations of any person other than a wholly-owned direct or indirect subsidiary outside the ordinary course of the business; (vi) Except in accordance with a divestiture otherwise specifically contemplated by ARTICLE 4 of this Agreement, the divestiture by the Company of any material business unit; (vii) Any transaction or series of related transactions (including, without limitation, the sale, purchase, exchange, or lease of assets, property, or services) with any affiliate (other than a wholly-owned direct or indirect subsidiary or UAG) unless (x) such transaction or series of related transactions is on terms that are no less favorable to the Company or its subsidiary, as applicable, than would be available in a comparable transaction in arm's-length dealings with an unrelated third party and (y) such transaction or series of related transactions involves payments of not more than $100,000 in the aggregate; provided, however, that this restriction shall not apply to the payment of reasonable and customary fees to directors of the Company or its subsidiaries; to the Company's employee compensation and other benefit arrangements, or to payments, or services -3- provided, under the Management Agreement among the Company, PTL, Transportation Resource Advisors, LLC, UAG and Opus dated as of the date hereof; and (viii) The execution of any agreement or the adoption by the Company of any resolution to do any of the foregoing unless such agreement or resolution is expressly conditioned on receipt of the requisite approval. The rights of UAG under this SECTION 2.1A are not transferable. B. UAG and TRP. The expansion or contraction of the Board of Directors to a number above four or, if the rights of Laurence Vaughan to serve as a director lapse, below three, shall require the approval of the directors nominated by each of UAG and TRP, and if requested by any of those directors, the approval of the majority of the outstanding Common Shares then held by them, voting as separate classes by written consent or at a special meeting called for that purpose in accordance with Delaware law. 2.2 CERTAIN SECURITY ISSUANCES. If TRP, in its reasonable business judgment, concludes that it is necessary for the Company to raise additional equity capital in order for the Company to avoid a covenant default under its then principal credit facility or to comply with legal regulations applicable to it, then each of the directors and Stockholders shall vote to approve such issuance and take such other actions, such as approving an amendment to the Company's Certificate of Incorporation to increase or change its authorized capital to effect the offering, as may be reasonably necessary to effectuate the offering; provided that the securities offered are offered at fair market value, as determined in accordance with reasonable procedures and methods established by the Board of Directors, and each Stockholder is offered the pre-emptive rights provided for in this Agreement. 2.3 CERTAIN DEFINITIONS AND CLARIFICATIONS.

ARTICLE 3. PRE-EMPTIVE AND RELATED RIGHTS 3.1 GRANT OF RIGHTS. If the Company hereafter proposes to issue or sell any Equity Securities (other than (A) as a dividend payable solely and ratably in Common Stock on its outstanding shares of Common Stock, (B) in connection with an acquisition, or (C) pursuant to an Option Plan), the Company shall first offer to each of the Stockholders a portion of the number or amount of such securities proposed to be so sold equal to the product of (x) the number of Shares or amount proposed to be so issued and sold (on an as converted basis, if applicable) multiplied by (y) a fraction, the numerator of which is the number of issued and outstanding Shares then owned by such Stockholder prior to such issuance and the denominator of which is the total number of issued and outstanding Shares then issued and outstanding and held by persons having pre-emptive and related rights under this SECTION 3.1, for the same price and upon the same terms and conditions as the securities are being offered in such transaction. 3.2 PROCEDURES. A. If, in accordance with this ARTICLE 3, the Company determines to issue additional Equity Securities, it shall cause an officer to give each Stockholder having pre-emptive and related rights hereunder notice, specifying in reasonable detail the nature and type of securities being offered and the price at which they are being offered, at least twenty-one (21) days before issuing any such securities. Within twenty (20) days of the receipt of that notice, each Stockholder shall have the right, by giving notice to the designated officer, but not the obligation, to purchase the securities being offered as provided herein. B. Any Stockholder desiring to exercise its pre-emptive and related rights hereunder must give to the Company written notice of its election to purchase up to a specified number of the securities proposed to be offered by the close of business on the twentieth day after the notice required by SECTION 3.2 was given to it. Such response shall set forth the Stockholder's acceptance of the offer and designate a number of Shares (or, if applicable, a value of securities) to be purchased by such Stockholder, which number may be fewer than, equal to, or more than the number of Shares that such Stockholder has a right to purchase under SECTION 3.1. If any Stockholder does not elect to purchase all of the offered Equity Securities that it has right to purchase under SECTION 3.1, the securities remaining shall be allocated to each other electing Stockholder in one or more successive allocations, up to the number or amount of securities specified in the election, pro rata, in the same proportion as the total number of Common Shares -5- held by that electing Stockholder bears to the total number of issued and outstanding Shares held by all electing Stockholders electing to purchase more than the maximum number of shares that they are entitled to purchase. C. Not later than ten (10) days after the date on which this offer of rights expires, the Company shall notify each electing Stockholder of the time and place of closing, the number or amount of securities allotted to it, and the purchase price therefor, whereupon each such electing stockholder shall become legally obligated to purchase such securities at the price and on the terms offered. D. Following the expiration of the offer and the giving of the notice required by SECTION 3.2A, the Company may thereafter offer and sell any of the Equity Securities not purchased by the Stockholders for a period of one hundred twenty (120) days on the terms and conditions set forth in the original notice to the Stockholders. Any of the Equity Securities not sold during that period may not thereafter be sold without first complying with the requirements of this ARTICLE 3. ARTICLE 4. PROVISIONS RESTRICTING AND RELATING TO THE TRANSFER OF SHARES 4.1 GENERAL RESTRICTION ON TRANSFER. In addition to any other restriction under applicable federal or state securities laws, no Stockholder shall transfer, give, donate, pledge, hypothecate, or otherwise encumber, alienate, or dispose of (or agree to do any of the foregoing) ("TRANSFER") to any person, whether voluntarily or by operation of law (subject to ARTICLE 5), any Shares now held or hereafter acquired by such Stockholder, except for Permitted Transfers under SECTION 4.2 or sales made in accordance with the terms and conditions hereafter set forth in this Agreement. Notwithstanding any other provision of this Agreement, no Stockholder will, except by operation of law, Transfer any Shares of Common Stock that it may hold prior to the second annual anniversary of the Effective Date. 4.2 PERMITTED TRANSFERS. Subject to all provisions of this ARTICLE 4 relevant to the Transfer, any Stockholder may Transfer Shares held by it to a Controlled Affiliate or to the Company. Any person to whom Shares held by a Stockholder are transferred in accordance with this SECTION 4.2 is hereinafter referred to as a "PERMITTED TRANSFEREE." The Transfer to a Permitted Transferee shall activate only SECTIONS 4.7 and 4.8 of this ARTICLE 4. 4.3 RIGHTS OF FIRST OFFER. A. Subject to the terms and conditions specified in this SECTION 4.3, and applicable securities laws, in the event any Stockholder proposes to offer or sell any Shares other than to a Permitted Transferee or other than in a transaction to which SECTION 4.4 applies, the selling Stockholder shall no less than thirty (30) days prior to effecting such sale make an offer of such Shares to each of the Initial Investors in accordance with the following provisions of this SECTION 4.3. An Initial Investor shall be entitled to apportion the right of first offer hereby granted it among itself and its Controlled Affiliates in such proportions as it deems appropriate. -6- B. The selling Stockholder shall deliver a notice (the "Offer Notice") to each of the Initial Investors stating (i) its bona fide intention to offer such Shares, and (ii) the number of such Shares to be offered and the terms and price on which they will be offered. C. By written notification received by the Company, within twenty (20) calendar days after mailing of the Offer Notice, each of the Initial Investors may elect to purchase or obtain, at the price, if any, and on the terms specified in the Offer Notice (if a price is specified), up to that portion of such Shares which equals the proportion that the number of Shares of issued and outstanding Common Stock, then held, by such Initial Investor bears to the total number of Shares of issued and outstanding Common Stock of the Company then held by all Initial Investors. The selling Stockholder shall promptly, in writing, inform each Initial Investor that elects to purchase all the Shares available to it (each, a "FULLY-EXERCISING INVESTOR") of any other Initial Investor's willingness or failure to do likewise. During the ten (10) day period commencing after receipt of such information, each Fully-Exercising Investor shall be entitled to obtain that portion of the Shares for which Initial Investors were entitled to subscribe but which were not subscribed for by the Initial Investors which is equal to the proportion that the number of Shares of Common Stock issued and then held, by such Fully-Exercising Investor bears to the total number of shares of Common Stock issued and held by all Fully-Exercising Investors who wish to purchase such unsubscribed shares. D. If all the Shares referred to in the Offer Notice are not elected to be purchased or obtained on the terms set forth in the Offer Notice, the selling Stockholder may, during the one hundred twenty (120) day period following the expiration of the period provided in SECTION 4.3C hereof, offer all of the Shares to any person or persons at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Offer Notice. If the Seller does not enter into an agreement for the sale of these Shares within such period, or if such agreement is not consummated within thirty (30) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such Shares shall not be offered unless first reoffered to the Initial Investors in accordance with this SECTION 4.3. E. The provisions of this SECTION 4.3 shall not apply to any sale effected pursuant to SECTIONS 4.4 OR 4.6 hereof. 4.4 TRP TAKE-ALONG RIGHTS. A. Subject to the rights of UAG in SECTION 4.4D, if at any time after the fourth annual anniversary of the effective date of this Agreement, TRP wishes to sell all, but not less than all, of the Shares then held by it in one transaction or a series of similar transactions (a "CONTROL TRANSACTION"), TRP may in its sole discretion, require each other Stockholder (in such capacity, a "TAKE-ALONG STOCKHOLDER") to sell all (but not less than all) of the Shares then held by it to such purchaser in accordance with this SECTION 4.4; provided that such Take-Along Stockholder shall only be required to sell its Shares at the same price per Share and upon substantially the same terms as TRP. B. If TRP elects to exercise its Take-Along Right in connection with a Control Transaction, it shall deliver a notice to each Take-Along Stockholder and to the Company, setting -7- forth the terms of the Control Transaction (including the proposed closing date for its consummation, which shall not be fewer than sixty (60) days after the effective date of such notice) and all documents required to be executed by each Take-Along Stockholder to consummate that Control Transaction. Each Take-Along Stockholder shall deliver to TRP at least seven (7) days prior to the proposed closing date, all documents previously furnished to the Take-Along Stockholder for execution in connection with the Control Transaction. If any Take-Along Stockholder fails to deliver these documents and the transaction is subsequently consummated, the Company shall cause its books and records to show that the Shares represented by the defaulting Stockholder are bound by the provisions of this section and that Shares held by it shall be transferred only to the third party who purchased the Shares in the Control Transaction. C. TRP shall have one hundred eighty (180) days from the date of its notice referred to above to consummate any Control Transaction and, promptly after such consummation, shall notify the Company and each Take-Along Stockholder to that effect and furnish evidence of the sale (including the time of sale) and of the terms thereof as any Take-Along Stockholder may reasonably request. TRP shall also cause to be remitted to each Take-Along Stockholder the proceeds of the sale attributable to the sale of that Take-Along Stockholder's Shares not later than the second business day following the sale (subject to any agreed holdbacks or escrows in connection with such sale. If any Control Transaction is not consummated prior to the expiration of the one hundred eighty (180) day period referred to in this section, TRP may not thereafter consummate the proposed Control Transaction and shall return to each Take-Along Stockholder all documents previously delivered to TRP in connection with that Control Transaction. D. TRP shall notify UAG not less than thirty (30) days prior to any anticipated exercise of its rights under this SECTION 4.4. Within such thirty (30) day period, UAG shall have the right to make an offer, which must remain open for not less than thirty (30) days, to purchase all, but not less than all, of the Company's outstanding Shares by giving notice to TRP, which notice shall include the price (the "UAG OFFER PRICE") and other material terms of such offer. If such offer is accepted by TRP while the offer is open, TRP and the other Stockholders shall sell their respective Shares to UAG, and UAG shall purchase all of such Shares, at the UAG Offer Price and on the other terms and conditions set forth in UAG's notice. The mechanics regarding sale, closing procedures and other matters (including as to escrows, holdbacks, and the delivery of purchase price and Shares to be sold) set forth in SECTIONS 4.4B AND 4.4C shall be applicable to the UAG purchase. If UAG does not exercise its right to make an offer to purchase (or affirmatively declines to make such an offer) within the thirty (30) day period specified above, or if TRP does not accept UAG's offer to purchase Shares, TRP may thereafter for a period of one hundred and eighty (180) days sell the Shares and exercise its rights under the terms hereof, provided however, that prior to any sale under this SECTION 4.4 at a price below the UAG Offer Price or on terms materially less favorable to TRP than those set forth in the UAG Offer, TRP shall again comply with the terms of this SECTION 4.4D. E. Notwithstanding anything in this SECTION 4.4 to the contrary, (i) there shall be no liability on the part of TRP to any Stockholder if any sale of Shares pursuant to this SECTION 4.4 is not consummated for whatever reason, and (ii) there shall be no liability on the part of UAG to any Stockholder, except for its failure to comply with the terms of its offer (if any) under SECTION -8- 4.4D. It is understood that TRP, in its sole discretion, shall determine whether to effect a sale of Shares to any person pursuant this SECTION 4.4. F. If the provisions of both this SECTION 4.4 and SECTION 4.6 apply to a transaction, the provisions of SECTION 4.6 shall govern. 4.5 OTHER STOCKHOLDER TAG-ALONG RIGHTS. A. If at any time, any Stockholder wishes to sell all but not less than all, of the Shares then held by it to any person (other than a sale by TRP to UAG pursuant to SECTION 4.4D above), then each other Stockholder (in such capacity, a "TAG-ALONG STOCKHOLDER") may, in its discretion, require the selling Stockholder to sell all of such Tag-Along Stockholder's Shares pursuant to such sale at the same price and substantially upon the same terms as the selling Stockholder proposes to sell its Shares. B. If at any time, any Stockholder (in such capacity, the "SELLING STOCKHOLDER") wishes to sell less than all of the Shares then held by it to any person, then each Tag-Along Stockholder may, in its discretion, require the Selling Stockholder to sell a portion of such Tag-Along Stockholder's Shares pursuant to such sale at the same price and substantially upon the same terms as the Selling Stockholder proposes to sell its Shares. In connection with such sale, each Tag-Along Stockholder shall have the right to sell up to that number of Shares (such Tag-Along Stockholder's "INCLUDED AMOUNT") equal to the product of X multiplied by Y, where: X = the total number of Shares proposed to be sold by the Selling Stockholder, and Y = a fraction, the numerator of which is the number of Shares owned by such Tag-Along Stockholder and the denominator of which is the number of Shares owned by all Tag-Along Stockholders who wish to participate in the sale of shares pursuant to this SECTION 4.5B plus the total number of Shares owned by the Selling Stockholder. C. In connection with a sale under this SECTION 4.5, the Selling Stockholder shall deliver a written notice to each other Stockholder and the Company (i) setting forth the terms of any sales to which this Section applies, (ii) offering such other Stockholder the right (the "TAG-ALONG RIGHT") to have such Stockholder's Shares included in such sale in accordance with SECTION 4.5A OR B above, and (iii) specifying the number of Shares equal to such Tag-Along Stockholder's Included Amount (which in the case of a sale of all of the Shares under SECTION 4.5A shall be all of such Tag-Along Stockholder's Shares) with respect to such sale, together with all documents required to be executed by such Tag-Along Stockholder in order to include such Tag-Along Stockholder's Shares in such sale. If any Tag-Along Stockholder exercises its Tag-Along Right in connection with any sale, such Tag-Along Stockholder shall deliver to the Selling Stockholder, prior to the expiration of the thirty (30) day period commencing on the date of the Selling Stockholder's notice, the certificate or certificates representing the number of Shares such Tag-Along Stockholder desires to include in such sale (which number may be less than such Tag-Along Stockholder's Included Amount with respect to a sale under SECTION 4.5B only), duly -9- endorsed, together with all documents previously furnished to such Tag-Along Stockholder for execution in connection with such sale. Delivery by any Tag-Along Stockholder of such certificate or certificates representing Shares and such other documents shall constitute an irrevocable exercise by the Tag-Along Stockholder of its Tag-Along Right with respect to such sale. To the extent any Tag-Along Stockholder exercises its Tag-Along Right with respect to a sale under SECTION 4.5B, the number of Shares proposed to be sold by the Selling Stockholder Seller pursuant to such sale shall be correspondingly reduced. D. The Selling Stockholder shall have up to one hundred eighty (180) days from the date of its notice referred to in SECTION 4.5C above to consummate any sale and, promptly after such consummation, shall notify the Company and each Tag-Along Stockholder to that effect and shall furnish evidence of such sale (including the time of sale) and of the terms thereof as the Company or such Tag-Along Stockholder may reasonably request. No later than the fifth day following such sale, the Selling Stockholder shall cause to be remitted (subject to any escrows or agreed holdbacks) to each Tag-Along Stockholder the proceeds of such sale attributable to the sale of such Tag-Along Stockholder's Shares. If any such sale is not consummated prior to the expiration of the 180-day period referred to in this SECTION 4.5D, the Selling Stockholder may not consummate such sale unless the Selling Stockholder again provides the Tag-Along Rights contemplated above to the other Stockholders and shall return to each Tag-Along Stockholder all certificates representing Shares that such Tag-Along Stockholder previously delivered to the Selling Stockholder in connection with such sale. E. Notwithstanding anything in this SECTION 4.5 to the contrary, there shall be no liability on the part of any Selling Stockholder to any Stockholder if any sale of Shares pursuant to this SECTION 4.5 is not consummated for whatever reason. It is understood that each Selling Stockholder, in its sole discretion, shall determine whether to effect a sale of Shares to any person pursuant this SECTION 4.5. F. If the provisions of both this SECTION 4.5 and SECTION 4.6 apply, SECTION 4.6 shall control. 4.6 DRAG-ALONG RIGHTS. Notwithstanding any other provision of this ARTICLE 4, if TRP and UAG together agree to Transfer for value all, but not less than all, of the Shares then held by them, or if the Board of Directors approves a sale of substantially all of the assets of the Company (which approval may only be granted in accordance with Article 2 hereof, then each Stockholder will consent to and raise no objections against the sale (the "APPROVED COMPANY SALE"). If the Approved Company Sale is structured as a sale of assets, a merger or a consolidation, then each Stockholder shall vote for, consent to, and waive any dissenters' or similar rights in connection with that sale, merger, or consolidation. If the Approved Company Sale is structured as a Transfer of Shares, then each Stockholder shall be obligated to sell all of its Shares and to participate in the Approved Company Sale and otherwise to take all necessary action to cause the Company and the Stockholders to consummate the Approved Company Sale, so long as all Stockholders receive the same consideration per Share on the same terms and conditions. 4.7 COOPERATION. The Company and the Stockholders shall use their respective commercially reasonable best efforts to aid in the consummation of any Control Transition or -10- Approved Company Sale, and in connection therewith, shall execute and deliver if so required a purchase agreement pursuant to which each Stockholder will severally (but not jointly) make representations and warranties relating to its ownership of and title to the Shares and provide indemnification in respect of such representations or warranties; provided that the sole source for payment of any such indemnity will be funds from the net proceeds otherwise distributed to the Stockholders. All Stockholders will bear their respective share of the costs of any actual or proposed Approved Company Sale to the extent such costs are incurred for the benefit of all Stockholders and not otherwise paid by the Company or the acquiring party. Costs incurred by Stockholders for their own behalf will not be considered costs of the Approved Company Sale; provided, that in any event, the Company will pay the reasonable attorneys' fees of one counsel chosen by the Stockholders to represent their interests. 4.8 OBLIGATIONS UPON TRANSFER. No Transfer (which, as used in this Agreement, shall include Transfers to Permitted Transferees) of any Shares permitted under this Agreement shall be effective unless the Company shall have received the favorable opinion of legal counsel of the Company or of other legal counsel acceptable to the Company to the effect that such Transfer is made in compliance with or is exempt from applicable securities laws. No Transfer of any Shares shall relieve the transferor from any of its obligations to the Company hereunder except to the extent that such obligations are assumed by the transferee in a legally valid and binding agreement and such transferee has complied with all provisions of this SECTION 4.8. All Transfers shall be by instrument in form and substance satisfactory to the Company's Board of Directors and shall include (A) a written, legally binding agreement of the transferee accepting all of the terms and conditions of this Agreement and an executed counterpart of this Agreement, as then in effect; (B) suitable representations by the transferee, including a representation by the transferee that such Transfer was made in accordance with all applicable laws and regulations and covering such other matters as the Company's Board of Directors may reasonably require; and (C) all such other instruments and agreements as the Company's Board of Directors may reasonably deem to be necessary or desirable to effectuate such Transfer. 4.9 INVALID TRANSFERS. Any purported Transfer of Shares not in accordance with the provisions of this Agreement shall be void and ineffective and shall not operate to Transfer any interest or title in such Shares to the purported transferee. The Company shall not cause or permit any Transfer of any Shares to be registered on its books unless such Transfer is made in accordance with the terms of this Agreement. The Company shall be protected in relying on the record of Stockholders maintained by it or on its behalf for all purposes, notwithstanding any notice of any purported Transfer to the contrary. 4.10 RIGHTS TO SEEK A SALE. Each of UAG and PTL shall have the right, at any time after the fourth anniversary of the Effective Date of this Agreement, to require TRP to use commercially reasonable best efforts to identify a purchaser for TRP's Shares and, in connection therewith, to exercise its rights pursuant to SECTION 4.4 in the event a sale of TRP's interests results. Notwithstanding the foregoing sentence, TRP shall not be required to sell its Shares and neither UAG nor PTL shall have the rights provided for in SECTION 4.3 or 4.4C in connection with any such sale. -11- ARTICLE 5. RIGHTS TO PURCHASE 5.1 RIGHT TO PURCHASE. The Company and each Initial Investor shall have the rights set forth below to purchase all, but not less than all, of the Shares held by any Stockholder (which for the purposes of this ARTICLE 5 shall include any Shares acquired by the Stockholder or his or her personal representative prior to the closing of a purchase by the Company or the other Stockholders and after the date of the event giving rise to the rights to purchase) in accordance with the provisions of this ARTICLE 5. A. If Shares owned by any Stockholder shall become subject to sale or other Transfer by reason of (i) bankruptcy or insolvency proceedings, whether voluntary or involuntary, (ii) attachment or garnishment; (iii) divorce; or (iv) distraint, levy, execution or other involuntary transfer (other than in accordance with the laws of descent and distribution), then such Stockholder or his or her personal representative shall give the Company written notice thereof promptly upon the occurrence of such event, stating the terms of such proposed Transfer, the identity of the proposed transferee, the price or consideration, if any, for which the Shares are proposed to be transferred, and the number of Shares and type and number of other interest to be Transferred. Upon receipt of such notice, or, failing such receipt, when the Company otherwise obtains actual knowledge of such Transfer, the Company shall have the right to purchase from the Stockholder, his or her personal representative, and the transferee, and, upon exercise of this option, the Stockholder, his or her personal representative, and the transferee shall be obligated to sell, all of the Shares owned by such persons and acquired from the Stockholder immediately prior to the occurrence of such event (or subsequently acquired as provided above), as shall be specified in the notice of exercise, for the price and upon such terms as set forth in SECTION 5.1A. If any Shares held by a Stockholder or his or her personal representative are transferred by operation of law (e.g., in the event of the bankruptcy or death or disability of a Stockholder or the attachment or garnishment of Shares), the transferee shall receive such Shares subject to the provisions of this Agreement, including, but not limited to, the rights granted to the Company and the other Stockholders to acquire such Shares. B. Fair market value shall be determined in good faith by the Board of Directors and promptly communicated to all Stockholders; provided that if the Stockholder whose Shares are to be purchasable for fair market value believes that the value determined by the Board is less than the actual value of the Shares, such Stockholder shall be entitled to request a valuation by an appraiser or investment banker reasonably acceptable to both that Stockholder and the Board of Directors, and the fair market value as determined by that appraiser or investment banker shall be final and binding on parties as the fair market value for the Shares. Any request for such an evaluation must be made within ten (10) days after notice of the Board of Directors' determination of fair market value has been delivered to the Selling Stockholder, and any valuation shall be made within thirty (30) days of the date on which it is requested, promptly communicated to the Company and to all Stockholders. Within ten (10) business days after the completion of any such valuation, the Company and any Stockholder shall have the right to revoke any exercise of its right to purchase such Shares (if made previously) by delivering written notice of revocation to the Selling Stockholder and all other Stockholders and the Company. The fees and expenses of any valuation pursuant to the preceding section shall be borne equally by the Company and the Selling -12- Stockholder requesting it, unless the appraisal indicates that the fair market value of the Shares is greater than 125% of the initial fair market value established by the Board of Directors, in which case the Company shall pay the cost of the appraisal, or if the fair market value determined by the appraisal is less than 75% of the initial fair market value as established by the Board, the Stockholder requesting that appraisal shall pay its entire cost. The Company shall immediately notify each Initial Investor when any right to purchase Shares arises pursuant to SECTION 5.1 and shall keep the Initial Investors fully and timely apprised of any decision that it may make to exercise or not exercise its right to purchase Shares (subject, in each case to required approvals under Article 2 hereof). If the Company does not exercise its right to purchase all Shares that it is entitled to purchase, the Initial Investors shall have the right to purchase any such Shares not purchased by the Company in a manner and proportion that fairly reflects their then ownership interest in the Shares pursuant to procedures established by the Board of Directors. If the Company and/or the Initial Investors do not together exercise their right to purchase all Shares held by the Selling Stockholder, or his estate, as applicable, within the specified time periods, that option shall terminate and the Shares proposed to be transferred may be transferred. 5.2 EXERCISE; TIMING. The purchase option arising pursuant to SECTION 5.1 must be exercised by the Company (or the Stockholders) by giving written notice to the Stockholder (or his or her personal representative, if applicable) within thirty (30) days after the right to purchase has accrued under SECTION 5.1. 5.3 CLOSING; CONSIDERATION TO BE PAID. A. At closing of any sale pursuant to this ARTICLE 5, the selling Stockholder or his or her personal representative (as applicable) shall deliver the Share certificates that are the subject of the sale free and clear of all liens, restrictions and encumbrances (except those arising from this Agreement), duly endorsed, and (if required by the Purchaser) with signature guaranteed, and accompanied by all documents necessary to effect such transfer. In consideration therefor, the purchaser(s) shall pay the purchase price. B. If at the date of closing the seller has any outstanding monetary obligation to the Company or to another purchaser, the Company and any such purchaser shall have the right to set-off any such obligations against the purchase price to be paid to the Seller by it, and that purchase price shall be reduced accordingly. The calculation of such setoff and the identification and amount of the obligation shall be given to the seller in a notice not less than five (5) days prior to the Closing. ARTICLE 6. MISCELLANEOUS. 6.1 REGISTRATION RIGHTS. Immediately prior to the closing of the Company's first firm commitment underwritten public offering of its Common Stock registered under the Securities Act -13- of 1933, as amended, the Company and each Stockholder shall enter into a Registration Rights Agreement providing, among other things, that commencing one hundred eighty (180) days after the completion of that public offering, each Stockholder and any group of Stockholders holding 15% or more of the Company's then outstanding Common Stock shall have the right to multiple "demand" registrations of their Common Stock on Form S-3 or a successor form thereto which permits incorporation by reference in, at the election of the Stockholders exercising registration rights, an underwritten public offering, or at their election, on a shelf registration statement. In addition, the Stockholders shall have the right under the Registration Rights Agreement to three (3) piggyback registrations, subject to customary cutbacks and other provisions. In connection with any registration, the Company shall agree to use its commercially reasonable best efforts to file, cause the registration statement to become effective, and cause the registration statement to remain effective in each case promptly. The selling Stockholders shall be responsible for paying, in connection with any registration, federal and state registration fees attributable to their shares, costs and expenses of any counsel retained to represent them as contrasted with the Company, underwriting discounts attributable to their Shares, and, in the case of an underwritten offering, printing and similar costs associated with the preparation and distribution of the registration statement and related prospectus. The Registration Rights Agreement shall include customary terms relating to the accuracy of information provided by the Company and the selling Stockholders, blackout periods, suspension of the prospectus upon notice from the Company, and indemnification by the Company and the selling Stockholders. 6.2 "MARKET STAND-OFF" AGREEMENT. In the event of the Company's first firm commitment underwritten public offering of its common stock registered under the Securities Act of 1933, as amended, each Stockholder hereby agrees that such Stockholder shall not sell or otherwise transfer or dispose of any Company securities held by such Stockholder (other than those included in the registration relating to such offering) for a period specified by the representative of the underwriters of the common stock being sold in such offering, which period shall not exceed one hundred eighty (180) days following the effective date of the registration statement of the Company filed under the Securities Act of 1933, as amended, relating to such offering. In furtherance of the foregoing, (A) each Stockholder agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter(s) which are consistent with the foregoing or which are necessary to give further effect thereto, and (B) the Company is authorized to impose stop-transfer instructions with respect to the securities subject to the foregoing restriction until the end of the applicable period. 6.3 EQUITABLE RELIEF. The parties acknowledge that the Shares are unique, and that any violation of this Agreement cannot be compensated for in damages alone. Therefore, in addition to all of the other remedies which may be available under applicable law, any party hereto shall have the right to equitable relief, including, without limitation, the right to enforce specifically the terms of this Agreement by obtaining injunctive relief against any actual or threatened violation or non-performance hereof. 6.4 GOVERNING LAW. This Agreement will be governed by and construed in accordance with the internal laws of the State of Delaware (and United States federal law, to the extent applicable) without giving effect to principles of conflicts of law. -14- 6.5 NOTICES.

A. Each and every dispute, difference, controversy or claim, whether based on contract, tort, common law, statute or equity (a "DISPUTE") arising out of or in connection with or related or incidental to, or question occurring under this Agreement shall be finally settled in accordance with the JAMS Comprehensive Arbitration Rules and Procedures (the "RULES") by a single arbitrator selected by mutual agreement of the parties to the Dispute within ten (10) days of receipt of a notice of arbitration of a Dispute or, if the parties fail to select an arbitrator by mutual agreement within such ten (10) day period, by JAMS in accordance with its Rules and this SECTION 6.5. Any arbitrator selected by JAMS shall be an attorney or retired judge experienced in corporate transactions. Arbitration of a Dispute shall be commenced by notice provided in accordance with this Agreement and the Rules. Each party to any arbitration proceeding hereunder -16- shall bear its own expenses in connection with such arbitration, including those of attorneys and experts, and each party thereto shall bear an equal percentage of the costs of the arbitrator and arbitration proceeding, e.g., the arbitration facilities and transcript. Failure to pay the fees of JAMS and the arbitrator when due shall constitute a separate breach of this Agreement for which the damages shall be awarded by the arbitrator and shall consist of the reasonable attorneys fees and costs incurred to obtain payment of such fees. The award of the arbitrator shall be rendered in the form of a reasoned award and shall be in writing. The arbitrator appointed pursuant to this SECTION 6.5, rather than a court, shall determine any and all challenges and disputes with respect to the arbitrability of a Dispute and the scope of the arbitration obligation under this Agreement. Furthermore, the arbitrator shall, rather than a court, determine all challenges to the enforceability of this Agreement and the obligation to arbitrate a Dispute. B. The location of all arbitration shall be Detroit, Michigan or any other place mutually agreed to by the parties to the arbitration proceeding. However, the arbitrator may hold an arbitration hearing at any location in or outside the State of New York when necessary to obtain the testimony or documents of third parties. C. The parties hereby exclude any right of appeal to any court on the merits of the Dispute. The provisions of this SECTION 6.5 may be enforced in any court having jurisdiction over the award or any of the parties or any of their respective assets, and judgment on the award (including without limitation equitable relief required for enforcement of the award) may be entered in any such court. D. The arbitration of Disputes under this SECTION 6.5 shall be governed, construed and enforced solely pursuant to the United States Arbitration Act, 9 U.S.C. Section 1 et seq. The arbitration laws of the states shall not apply. The law governing all substantive matters pertaining to his Agreement shall be that set forth in SECTION 4.2, above. 6.8 COUNTERPARTS. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original as against any party whose signature appears thereon, and all of which shall together constitute one and the same instrument. This Agreement shall become binding when one or more counterparts hereof, individually or taken together, shall bear the signature of the Company and all of the Stockholders. An executed counterpart of this Agreement and all amendments hereto shall be kept at the principal office of the Company and shall be made available for inspection by any interested party during regular business hours. 6.9 ASSIGNMENTS AND TRANSFERS. A. Subject to the restrictions on Transfer set forth herein and SECTION 6.12 hereof, this Agreement shall be binding upon and inure to the benefit of the respective parties hereto, and their personal representatives, estates, successors, and assigns, including any transferee of the Shares subject to this Agreement. As a condition to any sale of Equity Securities, the purchaser thereof shall agree to be bound by the terms hereof and any transfer or issuance not in compliance with this SECTION 6.9 shall be given the effect set forth in SECTION 4.9 hereof. -17- B. Subject to the limitations set forth in SECTIONS 1.1, 1.2 AND 2.1A, to the extent an Initial Investor or a transferee thereof has rights under SECTION 1.1, 2.1B, 2.2, 4.3. 4.4. OR 4.6 or ARTICLE 5 of this Agreement at the time of transfer, such rights may be transferred (and not retained) to any purchaser permitted hereunder of all, but not less than all, of the outstanding Shares then held by such Stockholder. C. The rights under SECTIONS 2.1A AND 4.10 are not transferable. D. The rights of any Initial Investor or its permitted successor under ARTICLES 1, 2, AND 5, and under SECTIONS 4.3 AND 4.4 shall lapse if such Stockholder ceases to hold of record at least 5% of the issued and outstanding Common Shares. 6.10 SEVERABILITY. If any provision of this Agreement is held to be invalid or unenforceable by any judgment of a tribunal of competent jurisdiction, it shall to that extent be omitted, but the remainder of this Agreement shall not be affected by such judgment, and the Agreement shall be carried out as nearly as possible according to its original terms and intent. In particular, if the provisions relating to Transfers of Shares in ARTICLE 5 are determined to constitute an impermissible restriction on transfer, the Company shall have the right to purchase such Shares upon thirty (30) days notice at the purchase price set forth in ARTICLE 5. 6.11 ENTIRE AGREEMENT; AMENDMENT. This Agreement represents the entire agreement and understanding of the parties with respect to the subject matter hereof and supersedes all prior written or oral agreements, representations and understandings relating to the subject matter hereof. This Agreement may be amended or modified at any time by the affirmative vote at a meeting duly called for that purpose of a majority of the Shares then outstanding voting as separate classes. 6.12 TERMINATION. This Agreement shall terminate upon the affirmative agreement of each of the Initial Investors. This Agreement, if not previously terminated, shall expire upon (x) the effective date of the first registration statement filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended, in connection with the initial firm commitment, underwritten public offering of the Company's common stock, (y) the sale to a third party of all of the outstanding Shares held by the Stockholders, or (z) a merger or combination of the Company with or into another company in which the Shares do not constitute a majority of the voting securities in the surviving corporation. 6.13 REPRESENTATIONS. Each of the Stockholders represents to the Company and to each other Stockholder that he is the sole record and beneficial owner of the number of Shares set forth next to his name on Schedule A and no other person has any right, title, or interest in or to the Shares which such schedule indicates that he owns. All such Shares are held by him free and clear of any liens, encumbrances, equities, options, or rights of another whatsoever. 6.14 SPOUSAL CONSENT. By signing this Agreement, each spouse of a Stockholder who is an individual consents to the execution and delivery hereof by his or her spouse, becomes a party to this Agreement, acknowledges that this Agreement restricts and limits certain rights he or she may have in securities of the Company and hereby agrees and consents to such limitations and restrictions. -18- 6.15 PRONOUNS. As used in this Agreement, the pronouns "it" and "its" shall mean, when referring to an individual, him, her, his, or hers (as applicable). 6.16 ISSUANCE OF ADDITIONAL SECURITIES. If the Company issues or agrees to issue any Preferred Stock or any Equity Security other than Common Stock or options to purchase Common Stock under an Option Plan, each Stockholder shall execute and deliver an amendment to this Agreement providing that all of its provisions other than those of ARTICLE 1 shall be applicable to such additional securities. In addition, if the Company adopts an Option Plan, and any person acquires shares of Common Stock or other equity Securities of the Company pursuant to it, such person as a condition of acquiring such shares or securities shall be required to join in this Agreement by executing an addendum hereunder; and, to the extent necessary, this Agreement shall be appropriately amended to reflect the terms and conditions under which such securities are issued.
