Each other Stockholder shall then have the right and option, for a period of twenty (20) days after the expiration of the 10-day period provided above, (x) to accept in writing all or any of his or its Proportionate Percentage of the Stockholders Shares so offered and not accepted by the Company at the purchase price and on the terms stated in the Notice of Offer and (y) to offer, in any written notice of acceptance, to purchase any Stockholder Shares not accepted by the other Stockholders pursuant to this sentence, in which case the Stockholder Shares not accepted by the other Stockholders shall be deemed, on the same terms and conditions, to be re-offered from time to time during such 20-day period to and accepted by the other Stockholders who exercised their option under this clause (y), PRO RATA in accordance with their respective Proportionate Percentages (computed without including the Stockholders who have not exercised their option to purchase Stockholder Shares under this clause (y)), until all such Stockholder Shares are fully subscribed or until all such other Stockholders have subscribed for all such offered Stockholder Shares which they desire to purchase. (c) Transfers of Stockholder Shares under the terms of this SECTION 2.4 shall be made at the offices of the Company on a mutually satisfactory Business Day within fifteen (15) days after the later of (i) expiration of the Offer Period and (ii) the satisfaction of any governmental approval or filing requirements, if any.

(d) If the Offerees shall not have accepted all of the Stockholder Shares offered for sale pursuant to the Notice of Offer, then the Offeror may Transfer to the Proposed Transferee that number of the Stockholder Shares not accepted by the Offerees in accordance with the terms set forth in the Notice of Offer, at any time within ninety (90) days after the expiration of the First Refusal Offer required by SECTION 2.4(a). Any such Transfer shall be in compliance with SECTION 2.2 and SECTION 2.3. In the event the Stockholder Shares are not Transferred by the Offeror to the Proposed Transferee on such terms during such 90-day period, the restrictions of this SECTION 2.4 shall again become applicable to any Transfer of Stockholder Shares by the Offeror. -11- <Page> 2.5 REQUIRED SALE IN CONNECTION WITH A SALE OF THE COMPANY.

Subject to the further provisions of this SECTION 2.5, if the Board and the Requisite Holders approve a Sale of the Company (an "APPROVED SALE"), each Stockholder shall consent to and raise no objections against the Approved Sale, and if the Approved Sale is structured as a sale of the issued and outstanding capital stock of the Company (whether by merger, recapitalization, consolidation or sale or Transfer of Stockholder Shares, other Securities or otherwise), then each Stockholder shall waive any dissenters rights, appraisal rights or similar rights in connection with such Sale of the Company and each Stockholder shall agree to sell his or its Stockholder Shares on the terms and conditions approved by the Board. Each Stockholder shall take all necessary and desirable actions in connection with the consummation of the Approved Sale, including the execution of such agreements and instruments and other actions necessary to provide the representations, warranties, indemnities, covenants, conditions, escrow agreement and other provisions and agreements relating to such Approved Sale. Each Stockholder hereby grants an irrevocable power of attorney and proxy to the Chairman of the Board of the Company to take all necessary actions and execute and deliver all documents deemed by such Person to be necessary or desirable to effectuate the terms of this SECTION 2.5, such power of attorney and proxy only to be exercisable in the event that such Stockholder fails for any reason to take any of the foregoing actions after reasonable notice thereof. The restrictions on Transfers of Stockholder Shares set forth in SECTIONS 2.1, 2.2, 2.3 and 2.4 shall not apply in connection with an Approved Sale. Notwithstanding anything to the contrary contained herein, a Sale of the Company that is not approved by all of the Investor Directors shall not be deemed to be an "Approved Sale." (b) PROCEDURE. The Company shall deliver written notice to each Stockholder setting forth in reasonable detail the terms (including price, time and form of payment) of any Approved Sale (the "DRAG NOTICE"). Within ten (10) days following receipt of the Drag Notice, each Stockholder shall deliver to the Company written notice (in form and substance reasonably satisfactory to the Company) setting forth such holders' agreement to consent to and raise no objections against, or impediments to, the Approved Sale (including, waiving all dissenter's and similar rights) and (ii) if the Approved Sale is structured as a sale of stock, to sell its Stockholder Shares on the terms and conditions set forth in the Drag Notice. (c) CONDITIONS TO OBLIGATION. The obligations of the Stockholders to participate in any Approved Sale pursuant to this SECTION 2.5 are subject to the satisfaction of the following conditions: (i) subject to SECTION 2.5(c)(iii), upon the consummation of the Approved Sale (or as promptly thereafter as practical in the case of certain options to purchase Stock, pursuant to outstanding option agreements), all of the Stockholders shall receive the same proportion of the aggregate consideration from such Approved Sale that such holder would have received if such aggregate consideration had been distributed by the Company in complete liquidation pursuant to the rights and preferences set forth in the Restated Certificate as in effect immediately prior to such Approved Sale (giving effect to applicable orders of priority and the exercise price of all warrants and options); -12- <Page> (ii) if any Stockholders are given an option as to the form and amount of consideration to be received with respect to shares in a class, all holders of shares of such class will be given the same option; (iii) all holders of then-currently exercisable or convertible Common Stock Equivalents will be given an opportunity to either (A) exercise or convert such rights prior to the consummation of an Approved Sale (but only to the extent such Common Stock Equivalents are then vested or would be vested on an accelerated basis upon such sale pursuant to the terms thereof) and participate in such sale as Stockholders or (B) upon the consummation of the Approved Sale, receive in exchange for such currently exercisable or convertible Common Stock Equivalents consideration equal to the product of (x) the same amount of consideration per Stockholder Share (of the same class as that for which the Common Stock Equivalent is exercisable or convertible) received by the holders of such class of capital stock in connection with the Approved Sale (less the exercise or conversion price per Common Stock Equivalent) and (y) the number of Common Stock Equivalents (but only to the extent such Common Stock Equivalents are then vested or would vest upon an accelerated basis upon such sale pursuant to the terms thereof); (iv) no Stockholder shall be obligated to pay more than his or its PRO RATA share (based upon the number of Common Stock Equivalents held by such Stockholder) of reasonable expenses incurred in connection with a consummated Approved Sale to the extent such expenses are incurred for the benefit of all Stockholders and are not otherwise paid by the Company or the acquiring party (expenses incurred by or on behalf of a Stockholder for its or his sole benefit not being considered expenses incurred for the benefit of all Stockholders); and (v) in the event that the Stockholders are required to provide any representations, warranties or indemnities in connection with an Approved Sale (other than representations, warranties and indemnities on a several basis concerning each Stockholder's valid ownership of his or its Stockholder Shares, free of all liens and encumbrances, enforceability and each Stockholder's authority, power, and right to enter into and consummate agreements relating to such Approved Sale without violating applicable law, its organizational documents or any other agreement to which it is a party), then each Stockholder shall not be liable for more than his or its PRO RATA share (based upon the number of Common Stock Equivalents held by such Stockholder) of any liability for misrepresentation or indemnity (except in respect of such several representations and warranties) and such liability shall not exceed the total purchase price received by such Stockholder (net of broker fees) from such purchaser for such Stockholder's Stockholder Shares and/or Common Stock Equivalents (including the exercise price thereof), and, to the extent that an indemnification, purchase price adjustment, or similar escrow has been established, such liability shall be satisfied solely out of any funds escrowed for such purposes prior to recourse against such Stockholder. (d) CONSULTATION WITH MANAGEMENT STOCKHOLDERS. Prior to the Company or the Requisite Holders, as applicable, executing a binding commitment for any Approved Sale (a "COMMITMENT"), the Investor Stockholders shall consult with the Requisite Management Holders -13- <Page> regarding the terms and conditions of such Approved Sale at least thirty (30) days prior to executing a Commitment. In addition, in the event of an Approved Sale whereby the form of consideration includes securities, the Investor Stockholders will use their reasonable, good faith efforts to structure such Approved Sale in a manner so that the Management Stockholders will receive securities having the same relative economic interest and rights as the Stockholder Shares held by such Management Stockholders immediately before the consummation of such Approved Sale; PROVIDED, HOWEVER, that the Investor Stockholders shall not have any obligation hereunder if such structure would result in less consideration or a greater detrimental economic effect to the Investor Stockholders than would otherwise be the case immediately prior to the consummation of any Approved Sale. 2.6 REPURCHASE RIGHT OF THE COMPANY. (a) If a Management Stockholder's employment with the Company is terminated for any reason or for no reason, the Company or its designee shall have the right (but not the obligation), upon delivery of a Repurchase Notice to such Management Stockholder, to repurchase from such Management Stockholder (and each of his Permitted Transferees) all or any part of the Stockholder Shares owned by such Management Stockholder (and each of his Permitted Transferees) at any time. The price per Stockholder Share to be paid by the Company shall be (i) in the event of a termination of such Management Stockholder's employment with the Company or any Subsidiary due to his death or disability or by the Company or such Subsidiary without Cause, the Fair Market Value as of the last day of the calendar month ending on, or immediately before, the date the Management Stockholders' employment with the Company is so terminated or (ii) in the event of a termination of such Management Stockholders' employment with the Company or any Subsidiary by the Company or such Subsidiary with Cause or upon the Management Stockholder's resignation, the lesser of the Original Cost and the Fair Market Value thereof as of the date of such termination. For purposes of this SECTION 2.6 only, the "Original Cost" of any share of the Company's Series B Preferred Stock, $0.001 par value per share, shall include that amount equal to the product of (X) the Original Cost of one share of Common Stock and (Y) the Participation Component Shares (as such term is defined in the Restated Certificate). The purchase price to be paid by the Company for any repurchase of Stockholder Shares pursuant to this SECTION 2.6 shall be paid in cash; PROVIDED, HOWEVER, that, if the Management Stockholder is terminated by the Company or such Subsidiary with Cause or resigns, the Company shall have the option to pay the purchase price as follows: (i) 33.333% of the purchase price in cash; PROVIDED FURTHER, HOWEVER, that the Company shall not be obligated to pay more than that which is permitted under the Credit Agreement, in which case such portion that is not permitted to be paid in cash shall be payable as provided in paragraph (ii) below; PROVIDED FURTHER, that the permitted amount referred to in the immediately preceding provision shall be reduced by an amount equal to the sum of all amounts paid or payable within the fiscal year in which such purchase is consummated in satisfaction of obligations owing pursuant to any notes issued, or to be issued in connection with the subject purchase of Stockholder Shares, pursuant to clause (ii) below; and (ii) the remaining portion of the purchase price in the form of a non-negotiable promissory note payable to the order of the Management Stockholder, which -14- <Page> note shall be (A) dated the date of the closing of such sale, bearing interest at the prime rate reported by J.P. Morgan Chase Bank, N.A. in the Wall Street Journal as of such closing date, (B) payable in three equal annual installments of principal and interest accrued thereon payable on an anniversary of the date of the note; PROVIDED, HOWEVER, that the aggregate amount required to be paid from time to time by the Company with respect to all of the outstanding notes issued pursuant to this SECTION 2.6(a)(ii) shall not exceed the amounts then permitted by the Credit Agreement or any covenant under any other financing document of the Company or its Subsidiaries (or any successor facility or facilities which contains restrictions on the payment of such notes which are not more restrictive than those currently contained in the Credit Agreement or such other document), and if such Credit Agreement or such other document does not permit the payment of all amounts payable in a fiscal year with respect to such notes, the amount permitted to be paid shall be allocated among such notes PRO RATA based upon the outstanding principal balances of such notes, (C) prepayable at any time without premium, such prepayments to be applied to payments of principal and then interest next due and (D) subordinated to any funded indebtedness of the Company and its Subsidiaries. (b) The purchasers of any Stockholder Shares pursuant to this SECTION 2.6 will be entitled to require all of the sellers of Stockholder Shares to provide representations and warranties from such seller regarding (i) such seller's power, authority and legal capacity to enter into such sale and to transfer valid right, title and interest in such Stockholder Shares, (ii) such seller's ownership of such Stockholder Shares and the absence of any liens, pledges, and other encumbrances on such Stockholder Shares and (iii) the absence of any violation, default, or acceleration of any agreement or instrument pursuant to which such seller or the assets of such seller are bound as the result of such sale. (c) If the Company or any of its designees elect to exercise the repurchase rights pursuant to this SECTION 2.6 and any seller fails to promptly deliver all of such Stockholder Shares in accordance with the terms hereof, then the purchaser of such Stockholder Shares hereunder may, at its option, in addition to all other remedies it may have, deposit the purchase price in an escrow account administered by an independent third party (to be held for the benefit of and payment over to such seller in accordance herewith), whereupon the Company shall by written notice to such seller (i) cancel on the Company's books the certificate(s) representing such Stockholder Shares registered in the name of such seller and (ii) issue to the purchaser, in lieu thereof, new certificate(s) representing such Stockholder Shares registered in the purchaser's name, and all of the seller's right, title, and interest in and to such Stockholder Shares shall terminate in all respects without any action on the part of such seller. (d) Anything contained in this Agreement to the contrary notwithstanding, all repurchases of Stockholder Shares by the Company or its designees pursuant to this SECTION 2.6 shall be subject to applicable restrictions contained in federal law, the law of any other applicable jurisdiction and in the Company's debt and equity financing agreements, including the Credit Agreement. Anything contained in this Agreement to the contrary notwithstanding, if any such restrictions prohibit or otherwise delay the repurchase of Stockholder Shares or any payment of money in connection therewith pursuant to this SECTION 2.6 which the Company is otherwise entitled or required to make, the Company or its designees may make such repurchases or such -15- <Page> payments as soon as it is permitted to do so under such restrictions. The restrictions on Transfers of Stockholder Shares set forth in SECTIONS 2.3, 2.4 and 2.7 shall not apply in connection with any Transfer in connection with this SECTION 2.6. (e) If Stockholder Shares are repurchased pursuant to this SECTION 2.6, then the sellers and the purchasers thereof and their respective successors, assigns and representatives shall take all steps necessary or desirable to obtain, at their sole cost and expense, all required third-party, governmental and regulatory consents and approvals (including any actions required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended) and shall take all other actions necessary or desirable to facilitate consummation of such repurchase in a timely manner. 2.7 RIGHT OF FIRST OFFER.

To the extent that MQ Holdings has not Transferred such Stockholder Shares within the Unlimited Transfer Period, MQ Holdings shall again comply with the provisions of this SECTION 2.7 prior to Transferring such Stockholder Shares that were not so Transferred; PROVIDED, HOWEVER, if such ROFO Transfer Notice was given in connection with, or in contemplation of, an Approved Sale, this last sentence of this clause (iii) shall be inapplicable and MQ Holdings shall be entitled to Transfer such Stockholder Shares without regard to this SECTION 2.7 for a period of three hundred and sixty-five (365) days following a Management Stockholders' Rejection (PROVIDED, that MQ Holdings shall be deemed to have satisfied the requirements of this proviso to this clause (iii) if MQ Holdings has entered into definitive documentation or is otherwise engaged in good faith negotiations in connection with such Transfer within such 365-day -16- <Page> period notwithstanding that the actual Transfer of such Stockholder Shares occurs after the expiration of such period); (iv) in the event that the Management Stockholders inform MQ Holdings in writing that they intend to purchase such Stockholder Shares (the "MANAGEMENT STOCKHOLDERS' OFFER"), the Management Stockholders shall indicate to MQ Holdings the per share price, in cash, they are willing to pay for such Stockholder Shares (the "MANAGEMENT STOCKHOLDERS AMOUNT") and evidence satisfactory to MQ Holdings of the source of financings of such purchase price and such Management Stockholders' Offer shall be irrevocable for ten (10) Business Days; (v) if MQ Holdings accepts the Management Stockholders' Offer, the Management Stockholders and MQ Holdings shall complete the Transfer of such Stockholders' Shares within five (5) Business Days after the later of (A) thirty (30) Business Days from the date of delivery of such acceptance by MQ Holdings to the Management Stockholders and (B) the satisfaction of any governmental approval or filing requirements, if any; and (vi) if MQ Holdings rejects the Management Stockholders' Offer, for a period of ninety (90) Business Days from the date of delivery of such rejection by MQ Holdings to the Management Stockholders (the "LIMITED TRANSFER PERIOD"), MQ Holdings shall be able to Transfer such Stockholder Shares, free and clear of the restrictions set forth in this SECTION 2.7, but subject to SECTION 2.3, to any other Person for a per share price that is not less than the Management Stockholders' Amount; PROVIDED, HOWEVER, that if such Transfer is in connection with an Approved Sale, such Limited Transfer Period shall be 180 Business Days.

In addition to any other restrictions on the Transfer of any Stockholder Shares contained in this Agreement, the Stockholders shall not Transfer any Restricted Securities except in compliance with the conditions specified in this ARTICLE V. 5.2 RESTRICTIVE LEGENDS. Each certificate for the Restricted Securities shall (unless otherwise provided by the provisions of SECTION 5.4) be stamped or otherwise imprinted with a legend in substantially the following terms: "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES OR BLUE SKY LAWS. THESE SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT OR LAWS." 5.3 NOTICE OF TRANSFER. The holder of any Restricted Securities, by his or its acceptance or purchase thereof, agrees, prior to any Transfer of any such Restricted Securities (except pursuant to an effective Registration Statement), to give written notice to the Company of such holder's intention to effect such Transfer and agrees to comply in all other respects with the provisions of this ARTICLE V and ARTICLE II. Each such notice shall describe the manner and circumstances of the proposed Transfer and, unless waived by the Company, shall be accompanied by the written opinion, addressed to the Company, of counsel for the holder of such Restricted Securities (which counsel shall be reasonably satisfactory to the Company), stating that in the opinion of such counsel (which opinion shall be reasonably satisfactory to the Company) such proposed Transfer does not involve a transaction requiring registration of such Restricted Securities under the Securities Act; PROVIDED, HOWEVER, that no such opinion of counsel shall be required in connection with any such Transfer to an Affiliate of such holder or to an "accredited investor" (as such term is defined in Rule 501 promulgated under the Securities Act) upon receipt by the Company of reasonably satisfactory evidence of such transferee's status as such. Subject to complying with the other applicable provisions hereof, such holder of Restricted Securities shall be entitled to consummate such Transfer in accordance with the terms of the notice delivered by him or it to the Company if -22- <Page> the Company does not reasonably object (on the basis that such Transfer violates the provisions of this ARTICLE V) to such Transfer within five (5) days after the delivery of such notice. Each certificate or other instrument evidencing the Restricted Securities issued upon the Transfer of any Restricted Securities (and each certificate or other instrument evidencing any untransferred balance of such Restricted Securities) shall bear the legend set forth in SECTION 5.2) unless (i) in such opinion of such counsel registration of future transfer is not required by the applicable provisions of the Securities Act or (ii) the Company shall have waived the requirement of such legend. 5.4 REMOVAL OF LEGENDS, ETC. Notwithstanding the foregoing provisions of this ARTICLE V, the restrictions imposed by SECTIONS 5.1, 5.2 and 5.3 upon the transferability of any Restricted Securities shall cease and terminate when (a) such Restricted Securities are sold or otherwise disposed of in accordance with the intended method of disposition by the seller or sellers thereof set forth in a Registration Statement or are sold or otherwise disposed of in a transaction contemplated by SECTION 5.3 which does not require that the Restricted Securities transferred bear the legend set forth in SECTION 5.2, or (b) the holder of such Restricted Securities has met the requirement of Transfer of such Restricted Securities pursuant to subparagraph (k) of Rule 144. Whenever the restrictions imposed by SECTIONS 5.1, 5.2 and 5.3 shall terminate, as herein provided, the holder of any Restricted Securities shall be entitled to receive from the Company, without expense, a new certificate not bearing the restrictive legend set forth in SECTION 5.2 and not containing any other reference to the restrictions imposed by SECTIONS 5.1, 5.2 and 5.3. 5.5 ADDITIONAL LEGEND. (a) Each certificate evidencing Stockholder Shares and each certificate issued in exchange for or upon the Transfer of any Stockholder Shares (if such shares remain Stockholder Shares as defined herein after such Transfer) shall be stamped or otherwise imprinted with a legend in substantially the following form: "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A STOCKHOLDERS' AGREEMENT DATED AS OF AUGUST [_], 2002 (AS THE SAME MAY FROM TIME TO TIME BE AMENDED, RESTATED, SUPPLEMENTED OR OTHERWISE MODIFIED IN ACCORDANCE WITH THE TERMS THEREOF, THE "AGREEMENT"), AMONG THE ISSUER OF SUCH SECURITIES (THE "COMPANY") AND CERTAIN OF THE COMPANY'S Stockholders. THE TERMS OF THE AGREEMENT INCLUDE, AMONG OTHER THINGS, RESTRICTIONS ON TRANSFERS. A COPY OF THE AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST."

Except as expressly set forth herein, the provisions of this Agreement may only be amended, modified or waived with the prior written consent of (a) the Company and (b) the Requisite Holders; PROVIDED, HOWEVER, that (i) any such amendment, modification, or waiver that would adversely affect the rights hereunder of any Stockholder, in its capacity as a Stockholder of a particular class (i.e., Investor Stockholders and Management Stockholders), without similarly affecting the rights hereunder of all Stockholders of the same class, in their capacities as Stockholders of such class, shall not be effective as to such Stockholder without his or its prior written consent, (ii) any such amendment, modification or waiver that would adversely affect the rights hereunder of any particular class of Stockholders, in their capacities as members of such class, without similarly affecting the rights hereunder of all other classes of Stockholders, shall not be effective as to such class of Stockholders without the prior written consent of the Stockholders of such class holding in the aggregate in excess of fifty percent (50%) of the Stockholder Shares held by such Stockholders as members of such class, (iii) any such amendment, modification, or waiver that would adversely affect the rights hereunder of JPMP Global Investors shall not be effective without its prior written consent, and (iv) SCHEDULE I to this Agreement shall be deemed to be automatically amended from time to time to reflect Transfers of Securities made in compliance with ARTICLE II and ARTICLE V without requiring the consent of any party, and the Company will, from time to time, distribute to the Stockholders a revised SCHEDULE I to reflect any such changes. 6.2 WAIVER. No course of dealing between the Company and the Stockholders (or any of them) or any delay in exercising any rights hereunder will operate as a waiver of any rights of any party to this Agreement. The failure of any party to enforce any of the provisions of this Agreement will in no way be construed as a waiver of such provisions and will not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms ARTICLE VII TERMINATION The provisions of this Agreement, except as otherwise expressly provided herein, shall terminate upon the first to occur of (a) the twentieth anniversary of the date hereof, (b) the dissolution, liquidation or winding-up of the Company, (c) the Sale of the Company, (d) the consummation of a Qualified Public Offering or (e) the approval of such termination by (i) the Company, (ii) the Requisite Holders and (iii) the Requisite Management Stockholders. Anything contained herein to the contrary notwithstanding, as to any particular Stockholder, this Agreement shall no longer be binding or of further force or effect as to such Stockholder, except as otherwise expressly provided herein, as of the date such Stockholder has Transferred all of -24- <Page> such Stockholder's interest in the Stockholder Shares and the Transferees of such Stockholder Shares have, if required by SECTION 2.2(b) hereof, executed Joinder Agreements. ARTICLE VIII MISCELLANEOUS 8.1 SEVERABILITY. It is the desire and intent of the parties hereto that the provisions of this Agreement be enforced to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of this Agreement shall be adjudicated by a court of competent jurisdiction to be invalid, prohibited or unenforceable for any reason, such provision, as to such jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. 8.2 ENTIRE AGREEMENT. This Agreement and the other Documents or agreements referred to herein and to be executed and delivered in connection herewith embody the entire agreement and understanding among the parties hereto with respect to the subject matter hereof and thereof and supersede and preempt any and all prior and contemporaneous understandings, agreements, arrangements or representations by or among the parties, written or oral, which may relate to the subject matter hereof or thereof in any way. Other than this Agreement, the other Documents and the other agreements or instruments referred to herein and to be executed and delivered in connection herewith, there are no other agreements continuing in effect relating to the subject matter hereof, including preemptive rights, rights of first refusal, voting of capital stock of the Company or election of members of the Board. 8.3 INDEPENDENCE OF AGREEMENTS, COVENANTS, REPRESENTATIONS AND WARRANTIES. All agreements and covenants hereunder shall be given independent effect so that if a certain action or condition constitutes a default under a certain agreement or covenant, the fact that such action or condition is permitted by another agreement or covenant shall not affect the occurrence of such default, unless expressly permitted under an exception to such initial agreement or covenant. In addition, all representations and warranties hereunder shall be given independent effect so that if a particular representation or warranty proves to be incorrect or is breached, the fact that another representation or warranty concerning the same or similar subject matter is correct or is not breached will not affect the incorrectness of or a breach of a representation and warranty hereunder. The exhibits and schedules attached hereto are hereby made part of this Agreement in all respects. -25- <Page> 8.4 SUCCESSORS AND ASSIGNS. Except as otherwise provided herein, this Agreement will bind and inure to the benefit of and be enforceable by the Company and its successors and assigns and the Stockholders and any subsequent holders of Stockholder Shares and the respective successors and assigns of each of them, so long as they hold Stockholder Shares. None of the provisions hereof shall create, or be construed or deemed to create, any right to employment in favor of any Person by the Company or any of its Subsidiaries. 8.5 COUNTERPARTS; FACSIMILE SIGNATURES; VALIDITY. This Agreement may be executed in any number of counterparts, and each such counterpart hereof shall be deemed to be an original instrument, but all such counterparts together shall constitute but one agreement. Facsimile counterpart signatures to this Agreement shall be acceptable and binding. The failure of any Stockholder to execute this agreement does not make it invalid as against any other Stockholder. 8.6 REMEDIES. (a) Each Stockholder shall have all rights and remedies reserved for such Stockholder pursuant to this Agreement and all of the rights which such Stockholder has under any law or equity. Any Person having any rights under any provision of this Agreement will be entitled to enforce such rights specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law or equity. (b) The parties hereto agree that if any parties seek to resolve any dispute arising under this Agreement pursuant to a legal proceeding, the prevailing parties to such proceeding shall be entitled to receive reasonable fees and expenses (including reasonable attorneys' fees and expenses) incurred in connection with such proceedings. (c) It is acknowledged that it will be impossible to measure in money the damages that would be suffered by any party hereto if any Person also party hereto fails to comply with any of the obligations imposed on it upon them in this Agreement or in the Restated Certificate or By-laws and that in the event of any such failure, the aggrieved party will be irreparably damaged and will not have an adequate remedy at law. Any such aggrieved party shall, therefore, be entitled to equitable relief, including specific performance, to enforce such obligations, and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law. 8.7 NOTICES. All notices, claims, requests, demands or other communications which are required or otherwise delivered hereunder shall be deemed to be sufficient and duly given if contained in a written instrument (a) personally delivered or sent by facsimile, (b) sent by nationally-recognized overnight courier guaranteeing next Business Day delivery or (c) sent by first class registered or certified mail, postage prepaid, return receipt requested, addressed as follows: -26- <Page> (a) if to the Company, to: MQ Associates, Inc. c/o J.P.

EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT. 8.10 MEDIATION; CONSENT TO JURISDICTION. (a) Except as provided herein, no civil action with respect to any dispute, claim or controversy arising out of this Agreement may be commenced until the matter has been submitted to JAMS, or its successor, for mediation. Any party hereto may commence mediation by providing to JAMS and the other parties a written request for mediation, setting forth the subject of the dispute and the relief requested. The parties will cooperate with JAMS and with one another in selecting a mediator from JAMS' panel of neutrals, and in scheduling the mediation proceedings. The parties' covenant that they will participate in the mediation in good faith. Subject to SECTION 8.6(b), each party shall pay it own attorneys' fees, costs and expenses in connection with the mediation and share equally in the fees and expenses charged by JAMS. All offers, promises, conduct and statements, whether oral or written, made in the course of the mediation by any of the parties, their agents, employees, experts and attorneys, and by the mediator and any JAMS employees, are confidential, privileged and inadmissible for any purpose, including impeachment, in any litigation or other proceeding involving the parties, PROVIDED that evidence that is otherwise admissible or discoverable shall not be rendered inadmissible or non-discoverable as a result of its use in the mediation. Either party may seek equitable relief prior to the mediation to preserve the status quo pending the completion of that process. Except for such an action to obtain equitable relief, neither party may commence a civil action with respect to the matters submitted to mediation until after the completion of the initial mediation session, or 60 days after the date of filing the written request for mediation, whichever occurs first. Mediation may continue after the commencement of a civil action, if the parties so desire. (b) Each of the parties hereto irrevocably submits to the non-exclusive jurisdiction of (a) the Supreme Court of the State of New York, New York County and (b) the United States District Court for the Southern District of New York, for the purposes of any suit, action or other proceeding arising out of this Agreement or the transactions contemplated hereby. Each of the -28- <Page> parties hereto further agrees that service of any process, summons, notice or document by U.S. registered mail to such party's respective address set forth in SECTION 8.7 shall be effective service of process for any action, suit or proceeding in the State of New York with respect to any matters to which it has submitted to jurisdiction in this SECTION 8.10(b). Each of the parties hereto irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby and thereby in (a) the Supreme Court of the State of New York, New York County or (b) the United States District Court for the Southern District of New York, and hereby and thereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. 8.11 FURTHER ASSURANCES. Each party hereto shall do and perform or cause to be done and performed all such further acts and things and shall execute and deliver all such other agreements, certificates, instruments, and documents as any other party hereto reasonably may request in order to carry out the provisions of this Agreement, the Documents and the consummation of the transactions contemplated hereby. 8.12 CONFLICTING AGREEMENTS. No Stockholder shall maintain or otherwise enter into any stockholder agreements or arrangements of any kind with any Person with respect to any Stockholder Shares on terms inconsistent with the provisions of this Agreement (whether or not such agreements or arrangements are with other Stockholders or with Persons that are not parties to this Agreement), including agreements or arrangements with respect to the acquisition or disposition of Stockholder Shares in a manner which is inconsistent with this Agreement. 8.13 THIRD PARTY RELIANCE. Anything contained herein to the contrary notwithstanding, except for SECTION 4.4 hereof the covenants of the Company contained in this Agreement (a) are being given by the Company as an inducement to the Stockholders to enter into this Agreement and the other Documents (and the Company acknowledges that the Stockholders have expressly relied thereon) and (b) are solely for the benefit of the Stockholders.
