ARTICLE IV

RIGHTS OF CERTAIN SHAREHOLDERS

                    SECTION 4.01. Rights of First Offer. (a) At any time or from time to time prior to a Qualifying Public Equity Offering, in the event that a Shareholder (other than Sponsor and its Affiliates) desires to Transfer all or part of its Common Stock (such shares being the “Offered Shares” and such proposed Shareholder transferor being the “Offeror”), other than pursuant to Section 3.02(a), 3.02(d), 4.02 or 4.03 of this Agreement, such Shareholder shall give prompt written notice (an “Investor’s Notice”) of its desire to sell the Offered Shares to the Company and Sponsor. The Investor’s Notice shall identify (x) the number of Offered Shares and (y) all other material terms and conditions of the proposed Transfer including the purchase price and the form of the consideration.

                    (b) The Company shall have the right, but not the obligation, to purchase all, but not less than all, the Offered Shares (the “First Option”) on the same terms and conditions as set forth in the Investor’s Notice, which option shall be exercised by delivering to such Shareholder irrevocable written notice of its commitment to purchase the Offered Shares within fifteen (15) business days after receipt of the Investor’s Notice (the “Company Option Period”). Failure by the Company to give such notice within such fifteen (15) business day period shall be deemed an election by the Company not to purchase the Offered Shares.

                    (c) In the event that the Company decides not to purchase the Offered Shares pursuant to Section 4.01(b), then Sponsor shall have the right, but not the obligation, to purchase all, but not less than all, the Offered Shares (the “Second Option”) on the same terms and conditions as set forth in the Investor’s Notice, which option shall be exercised by delivering to such Shareholder irrevocable written notice of its commitment to purchase the Offered Shares within ten (10) business days after the termination of the Company Option Period (the “Sponsor Option Period”); provided that Sponsor may, at its sole option, but subject to following the procedures of the next sentence (if applicable), assign its rights to purchase Offered Shares pursuant to this Section 4.01 to another Shareholder or a Permitted Transferee of

Sponsor (such person an “Assignee”). If a proposed Assignee is a Shareholder (other than an Affiliate of Sponsor) as of the date of the Investor’s Notice, then Sponsor shall offer each Shareholder (other than the Offeror, but including the proposed Assignee) the right, but not the obligation, to purchase not less than its percentage equivalent of a fraction, the numerator of which is the number of such Shareholder’s shares of Common Stock and the denominator of which is the aggregate number of all shares of Common Stock owned by Shareholders (other than the Offeror) each as of the date of the Investor’s Notice, of the Offered Shares on the same terms and conditions as set forth in the Investor’s Notice. Nothing shall preclude Sponsor from retaining its relative share of the Offered Shares if it so elects. Failure by Sponsor or its Assignee to give such notice within such ten (10) business day period shall be deemed an election by Sponsor or its Assignee not to purchase the Offered Shares.

                    In the event that a Heartland Entity (other than the Company and its subsidiaries) acquires shares of Common Stock (or the existing warrant therefor) from MCLLC (but not any transferee thereof other than a Direct Permitted Transferee of MCLLC), it shall promptly give written notice thereof to each Shareholder (other than MCLLC and its Direct Permitted Transferees) (each an “Offeree” and collectively the “Offerees”), and each Offeree shall have the right, but not the obligation, to purchase from such Heartland Entity not less than the percentage equivalent of a fraction, the numerator of which is the number of shares of such Offeree’s Common Stock and the denominator of which is the total number of shares of Common Stock owned by Offerees and the Heartland Entities immediately before such Heartland Entity acquired such Common Stock (or the existing Warrant therefor) from MCLLC or a Direct Permitted Transferee thereof, of such Common Stock at the same price as paid by the applicable Heartland Entity. Nothing herein shall preclude any Heartland Entity from retaining or receiving its relative share of the Common Stock (or the existing warrant therefor) acquired from MCLLC or a Direct Permitted Transferee thereof. Each Shareholder’s right to purchase Common Stock pursuant to this paragraph shall be for ten (10) business days after the notice referred to earlier in this paragraph is given by such Heartland Entity.

                    (d) Delivery of written notice by the Company, Sponsor or its Assignee accepting the First Option or the Second Option, as the case may be, shall constitute a contract between the Company, Sponsor or its Assignee, on the one hand, and such Shareholder on the other hand, for the purchase and sale of the Offered Shares on the terms and conditions set forth in the Investor’s Notice. The purchase of any Offered Shares pursuant to the exercise of the First Option or the Second Option, as the case may be, shall be completed not later than forty-five (45) days following receipt of the Investor’s Notice with respect to the Offered Shares, subject to receipt of any required material third-party or governmental approvals, compliance with applicable laws and the absence of any injunction or similar legal order preventing such transaction (collectively, the “Conditions”) in which case the purchase of the Offered Shares shall be delayed pending the satisfaction of the Conditions up to an additional thirty (30) days. As a condition to entering into the contract referred to above, the Company,

Sponsor and its Assignee will agree to use commercially reasonable efforts to satisfy the Conditions as soon as possible. In the event that neither the First Option nor the Second Option is exercised, the Shareholder shall have the right for a period of seventy-five (75) days after the termination of the Sponsor Option Period to Transfer (the “Investor Sale”) the Offered Shares at a price not less than ninety percent (90%) of the price contained in, and otherwise on terms and conditions no less favorable to such Shareholder than those set forth in, the Investor’s Notice, except that the purchase of the Offered Shares may be delayed up to an additional thirty (30) days pending satisfaction of the Conditions; provided that the Transferee agrees to execute a Joinder Agreement. If the Investor Sale is not consummated pursuant to the terms of the immediately preceding sentence, the Shareholder will not effect Transfer of any of the Offered Shares without commencing de novo the procedures set forth in this Section 4.01.

                    SECTION 4.02. Tag-Along Rights. (a) If, at any time or from time to time prior to a Qualifying Public Equity Offering, Sponsor or any of its Affiliates (but not including Metaldyne or any of its subsidiaries or the Company and any of its Subsidiaries) (the “Sponsor Transferor”) proposes to Transfer any shares of Common Stock to a Person (the “Purchaser”), other than pursuant to Section 3.02(a), 3.02(d), 5.01 or 5.02 or in a circumstance where all of the shares owned by all the Shareholders are being purchased pursuant to Section 4.03, the Sponsor Transferor shall give written notice (a “Transfer Notice”) of such proposed Transfer to the Shareholders at least fifteen (15) days prior to the consummation of such proposed Transfer, setting forth (A) the total number of shares of Common Stock offered to be Transferred to Purchaser, (B) the consideration to be received for such shares of Common Stock by the Sponsor Transferor, (C) the identity of the Purchaser(s), (D) any other material terms and conditions of the proposed Transfer, (E) the expected date of the proposed Transfer and (F) that each such Shareholder shall have the right (the “Tag-Along Right”) to elect to sell up to its Pro Rata Portion of such shares of Common Stock to be Transferred to Purchaser. If any portion of the consideration contained in the Transfer Notice includes consideration other than cash, the Sponsor Transferor shall provide the Shareholders with a summary of a valuation study, if any, that the Sponsor Transferor has prepared concerning such consideration, but the Sponsor Transferor shall have no liability to any Shareholder with respect to any such summary or study and no obligation to undertake any such valuation. Notwithstanding the first sentence of this Section 4.02(a), MCLLC and each Shareholder will have a Tag-Along Right in connection with Transfers of shares of Common Stock by the Sponsor Transferor to a Permitted Transferee (other than an Affiliate of the Sponsor Transferor) when the Sponsor Transferor Transfers shares of Common Stock to such Person at a price per share (as adjusted for Adjustments) that is greater than the price per share (as adjusted for Adjustments) paid for such shares by the Sponsor Transferor.

                    (b) Upon delivery of a Transfer Notice, each Shareholder has the option, but not the obligation, to sell up to the Pro Rata Portion of its shares of Common Stock at the same price per share of Common Stock and pursuant to the same terms and conditions with

respect to payment for the shares of Common Stock as agreed to by the Sponsor Transferor, by sending written notice to the Sponsor Transferor within ten (10) days of the date of the Transfer Notice, indicating its election to sell up to the Pro Rata Portion of its shares of Common Stock in the same transaction. To the extent that elections pursuant to this Section 4.02(b) are not made with respect to any shares of Common Stock included in a Transfer Notice within such 10-day period, then the Sponsor Transferor shall re-offer to Shareholders who have elected to sell their Pro Rata Portion (the “Tag-Along Shareholders”) for one additional three day period, the right to sell such additional number of shares as will result in the Tag-Along Shareholders being able to sell their pro rata share of such remaining shares of Common Stock, based upon all the shares of Common Stock being sold by all the Tag Along Shareholders (not including the remaining shares). For a sixty (60) day period following such ten (10) day period (which period may be extended an additional thirty (30) days in order to satisfy the Conditions), each Tag-Along Shareholder shall be permitted to sell to the Purchaser(s) on the terms and conditions set forth in the Transfer Notice that amount of its shares of Common Stock as to which it has made its election and the Sponsor Transferor shall be permitted to concurrently sell the balance of the shares of Common Stock that are the subject of the Transfer Notice that are not sold by the Tag-Along Shareholders.

                    (c) The provisions of Sections 4.02(a) and (b) shall not apply to any Transfer or series of Transfers by Sponsor of shares of Common Stock to one or more Persons other than Permitted Transferees (x) which are effected in order to comply with the preemptive rights provisions of Section 4.05 of the Metaldyne Shareholders Agreement with respect to Sponsor’s investment in the Company pursuant to the TriMas Purchase Agreement or (y) which are effected within one year of the date hereof at a price per share of not greater than $20.00 per share (as adjusted for Adjustments); provided that, after giving effect to any such Transfer referred to in this clause (y), Sponsor would own, together with its Affiliates (not including Metaldyne and its subsidiaries), thirty percent (30%) or more of the outstanding shares of Common Stock.

                    (d) Each Tag-Along Shareholder shall not be required to make representations and warranties in connection with such sale other than customary representations and warranties with respect to (i) such Shareholder’s due organization, power and authority, (ii) such Shareholder’s ownership of the shares of Common Stock and ability to freely convey such shares of Common Stock without liens or encumbrances, (iii) customary representations regarding non-contravention of such Shareholder’s charter, bylaws or other organizational documents or material agreements of such Tag-Along Shareholder and (iv) the enforceable nature of such Tag-Along Shareholder’s obligations under the documents for such sale to which it is a party (collectively, the “Shareholder Representations”). No Tag-Along Shareholder shall be liable in respect of any indemnification provided in connection with a sale of Common Stock pursuant to this Section 4.02 (a “Tag-Along Sale”), (with respect to such Shareholder’s Shareholder Representations) in excess of the consideration received by such

Tag-Along Shareholder in such Tag-Along Sale and no Tag-Along Shareholder shall be required to participate in any escrow relating to such Tag-Along Sale in excess of such Tag-Along Shareholder’s participation in the Tag-Along Sale.

                    (e) In the event that no Shareholder elects to sell shares of Common Stock pursuant to this Section 4.02, Sponsor and/or its Affiliates (as the case may be) shall have the right for a period of seventy-five (75) days (which period may be extended by an additional thirty (30) days to satisfy the Conditions) after the expiration of the 10-day period referred to in Section 4.02(b) to Transfer the Shares subject to the Transfer Notice to the Purchaser at a price not greater than the price contained in, and otherwise on terms and conditions no more favorable to Sponsor and/or such Affiliates than those set forth in, the Transfer Notice; it being agreed that, after the end of the 75-day period referred to in this Section 4.02(e) (including any permitted extension thereof), Sponsor and/or such Affiliates will not effect any transaction in any shares of Common Stock that are the subject of the Transfer Notice without commencing de novo the procedures set forth in this Section 4.02.

                    SECTION 4.03. Drag-Along Rights. If at any time prior to a Qualifying Public Equity Offering, Sponsor and its Affiliates intend to effect a Substantial Change of Control, Sponsor shall have the right to require the other Shareholders (the “Drag-Along Shareholders”) to sell the same percentage of Common Stock held by them relative to such Shareholder’s ownership of Common Stock as Sponsor and its Affiliates are selling in such transaction in connection with such Substantial Change of Control; to vote such Common Stock, whether by proxy, voting agreement or otherwise in favor of the transactions constituting a Substantial Change of Control; to waive their appraisal or dissenters’ rights with respect to such transaction; or otherwise participate in such Substantial Change of Control and each other Shareholder agrees to take any and all reasonably necessary action in furtherance of the foregoing; provided that (a) the consideration to be received by the other Shareholders shall be for the same type and amount per share of consideration received by Sponsor, and (b) after giving effect to such transaction, Sponsor and its Direct Permitted Transferees shall have sold the same percentage of their holdings of Common Stock as sold by the Drag-Along Shareholders; provided, however, that MCLLC and its Direct Permitted Transferees will not be obligated to participate in such transaction if the consideration per share in such transaction is less than $20.00 per share (as adjusted for Adjustments) of the Common Stock, and provided, further, that if Sponsor and its Affiliates are selling all of their shares of Common Stock in connection with such Substantial Change of Control, the Drag- Along Shareholders will be required to sell all of their shares pursuant to this Section 4.03. In connection with the sale of their shares of Common Stock pursuant to this Section 4.03, the Drag-Along Shareholders shall not be required to make any representations and warranties other than the Shareholder Representations. In addition, no Drag-Along Shareholder shall be liable in respect of any indemnification in connection with a transaction effected pursuant to this Section 4.03 (a “Drag-Along Transaction”) (with respect to such Shareholder’s Shareholder Representations) in

excess of the consideration received by such Drag-Along Shareholder in such Drag-Along Transaction and no such Drag-Along Shareholder shall be required to participate in any escrow relating to such Drag-Along Transaction in excess of the amount of Common Stock such Drag-Along Shareholder is required to sell pursuant to this Section 4.03.

                    SECTION 4.04. Information. (a) Prior to the occurrence of an Initial Public Offering, the Company shall deliver to each Shareholder

                    (b) In the case of any Shareholder (other than MCLLC) prior to the occurrence of a Qualifying Public Equity Offering, and for so long as such Shareholder owns

twenty-five percent (25%) or more of the number of shares of Common Stock (as adjusted for Adjustments) owned by such Shareholder as of the date of the amendment and restatement hereof or in the case of MCLLC, for so long as MCLLC retains a number of shares of Common Stock equal to at least twenty-five percent (25%) of the number of shares of Common Stock (as adjusted for Adjustments) owned by MCLLC immediately following the Transactions, the Company shall deliver to each such Shareholder and MCLLC

          (1) the information and reports provided pursuant to Sections 4.04(a)(1) and (2);

          (2) monthly “flash reports” utilized by the Company in its own management containing summarized, abbreviated data with respect to income statement amounts, balance sheet data and cash flows to the extent available; and

          (3) such other information concerning the condition or operations, financial or otherwise, of the Company and its subsidiaries as a Shareholder may, from time to time, reasonably request.

                    (c) The rights to receive the information set forth in subsections (1) and (2) of paragraph (a) shall be assignable to Transferees of Common Stock and Permitted Transferees that become Shareholders. The rights to receive the information set forth in subsections (2) and (3) of paragraph (b) shall be assignable to a Transferee that acquires from MCLLC at least fifty percent (50%) of the shares of Common Stock owned by MCLLC as of the date hereof (as adjusted for Adjustments).

                    (d) Prior to the occurrence of a Qualifying Public Equity Offering, and for so long as a Shareholder owns twenty-five percent (25%) or more of the number of shares of Common Stock (as adjusted for Adjustments) owned by such Shareholder on date of the amendment and restatement hereof, Representatives of such Shareholder shall be provided with a reasonable opportunity to discuss the business and affairs of the Company with the Company’s senior managers, directors, officers and senior employees upon reasonable advance notice during normal business hours; provided that such Company representatives shall be available to such Shareholder for an annual meeting with senior management at which the following year’s budget is presented and to MCLLC for quarterly meetings at which the most recent quarterly results are discussed.

                    (e) Each Shareholder hereby agrees that neither it nor its Representatives will disclose to any third party any information provided to it or its Representatives by the Company hereunder which is not generally available to the public, except with the prior express approval of the Company or as may be required by applicable law; it being understood that nothing in this Section 4.04(f) will restrict the ability of a Shareholder to disclose certain

information to its investors in accordance with its governing documents; provided that such investors agree to be bound by the confidentiality provisions of this Agreement.

                    (f) Notwithstanding the above, access to highly confidential proprietary information and facilities need not be provided by the Company, nor shall the Company be required to provide information to any Shareholder that is a competitor or reasonably likely to become a competitor of the Company or any of its subsidiaries; it being understood that the Shareholders and parties to the Metaldyne Shareholder’s Agreement existing as of the date hereof are not competitors.

                    SECTION 4.05. Preemptive Rights. (a) Prior to the occurrence of an Initial Public Offering, the Company hereby grants and hereby agrees to cause each Significant Subsidiary of the Company to grant to each Shareholder the right to purchase up to such Shareholder’s Proportionate Percentage (as hereinafter defined) of any future Eligible Offering (as hereinafter defined). For purposes of this Section 4.05, the following terms shall have the meanings set forth below.

          “Proportionate Percentage” means, with respect to any Shareholder as of any given date with respect to an Eligible Offering, the number (expressed as a percentage) obtained by dividing (A) the number of shares of Common Stock owned by such Shareholder as of such date by (B) the total number of shares of Common Stock held by all Shareholders.

          “Eligible Offering” means an offer by the Company or a Significant Subsidiary of the Company to sell to any Person or Persons for cash, any Capital Stock of the Company or a Significant Subsidiary, other than an offering by the Company or a Significant Subsidiary of the Company:

          (i) of Common Stock in an underwritten public offering (a “Public Offering”) registered under the 1933 Act or pursuant to a Rule 144A offering under the 1933 Act;

          (ii) of Common Stock issued upon the exercise of options, warrants or convertible securities outstanding as of the date hereof;

          (iii) of Common Stock or options to purchase shares of Common Stock in connection with or pursuant to any stock option, stock purchase plan or agreement or other benefit plans approved by the Board of Directors of the Company to full-time employees, officers, directors, consultants and/or advisors to the Company or its subsidiaries (excluding employees of Sponsor);

          (iv) of Common Stock issued in connection with restricted stock awards;

          (v) of Capital Stock of the Company issued as consideration to any seller in connection with the acquisition by the Company or any subsidiary of the Company of the assets of any Person in any transaction approved by the Board of Directors of the Company;

          (vi) of Capital Stock of the Company issued as an inducement in connection with any debt financing of the Company, subject to terms and conditions approved by the Board of Directors of the Company;

          (vii) of Capital Stock of a Significant Subsidiary of the Company in connection with any sale of control of such Significant Subsidiary to, or any joint venture between such Significant Subsidiary and a third party that is not a financial sponsor or investor, which sale or joint venture is approved by the Board of the Directors of the Company; and

          (viii) of director qualifying or similar shares of a Significant Subsidiary.

                    For purposes of this Section 4.05 only, “Capital Stock” means any and all shares of common stock or options, warrants or similar instruments or any other securities convertible or exchangeable or exercisable therefor (collectively, “Equity Interests”) or any equity security linked to or offered or sold in connection with any Equity Interests of such Person or any of its Significant Subsidiaries, as the case may be.

                    (b) The Company shall, before any securities are issued pursuant to an Eligible Offering, give written notice (a “Preemptive Notice”) thereof to each Shareholder that is entitled to preemptive rights hereunder. Such notice shall specify the security or securities proposed to be issued, the proposed date of issuance, the consideration that the Company or such Significant Subsidiary intends to receive therefor and all other material terms and conditions of such proposed issuance. For a period of ten (10) days following the date of such notice, each such Shareholder shall be entitled, by written notice to the Company, to elect to purchase all or part of such Shareholder’s Proportionate Percentage of the securities being sold in the Eligible Offering. To the extent that elections pursuant to this Section 4.05(b) shall not be made with respect to any shares of Capital Stock included in a Preemptive Notice within such 10-day period, then the Company shall re-offer to Shareholders who have elected to purchase their Proportionate Percentage (the “Preemptive Shareholders”) for one additional three-day period, the right to purchase any part of the shares of Capital Stock not purchased by other Shareholders (the “Section 4.05 Remaining Shares”) pursuant to this Section 4.05 which is equal to the product obtained by multiplying (i) the number of Section 4.05 Remaining Shares

-20-

by (ii) a fraction, the numerator of which is the number of shares of Common Stock then owned by any such Preemptive Shareholder and the denominator of which is the aggregate number of shares owned by all Preemptive Shareholders. To the extent that elections pursuant to this Section 4.05(b) shall not be made with respect to any securities included in an Eligible Offering within such ten (10) day period, then the Company or such Significant Subsidiary, as the case may be, shall not be obligated to issue to such Shareholder such securities for which such Shareholder has elected not to purchase. To the extent that there are securities that have not been purchased pursuant to this Section 4.05, then the Company or such Significant Subsidiary, as the case may be, may issue such securities, but only for consideration not less than, and otherwise on no less favorable terms to the Company or such Significant Subsidiary, as the case may be, than, those set forth in the Preemptive Notice and only within thirty (30) days after the end of such ten (10) day period. In the event that any such offer is accepted by any such Shareholder or Shareholders, the Company or such Significant Subsidiary, as the case may be, shall sell to such Shareholder or Shareholders, and such Shareholder or Shareholders shall purchase from the Company or such Significant Subsidiary, as the case may be, for the consideration and on the terms set forth in the notice as aforesaid, the securities that such Shareholder or Shareholders shall have elected to purchase within ten (10) days of such Shareholder’s election to purchase such Proportionate Percentage (subject to delay for an additional thirty days for satisfaction of the Conditions).

                    (c) The Company may comply with any applicable securities laws before issuing any shares of Capital Stock pursuant to this Section 4.05 and shall not be in violation of the provisions hereof by reason of such compliance; provided it is using commercially reasonable efforts to so comply.

                    SECTION 4.06. Board of Directors. (a) At each annual or special stockholders meeting called for the election of directors, and whenever the Shareholders of the Company act by written consent with respect to the election of directors, each Shareholder agrees to vote or otherwise give such Shareholder’s consent in respect of all shares of the Capital Stock of the Company (whether now owned or hereafter acquired) owned by such Shareholder, and take all other appropriate action and the Company shall take all necessary and desirable actions within its control in order to cause:

          (i) an amendment to the Bylaws of the Company to provide that the authorized number of directors on the Board of Directors of the Company shall be as recommended by the Sponsor in its sole discretion; provided such number not be less than the number of directors needed to satisfy MCLLC’s right to a director under Section 4.06(a)(ii)(2) and CSFB Plan Partner’s right to a director under Section 4.06(a)(ii)(3);

          (ii) the election to the Board of Directors of

	(1)		such number of directors as shall constitute a majority of the Board of Directors as designated by Heartland Industrial Partners, L.P.;
	(2)		one director designated by MCLLC; provided that upon MCLLC and its subsidiaries ceasing to own at least 20% of the outstanding shares of Common Stock owned by MCLLC immediately following the Transactions (as adjusted for Adjustments), MCLLC shall no longer have the right to designate one director to the Board of Directors of the Company; and
	(3)		one director designated by the CSFB Plan Partner (as defined in the Metaldyne Shareholders Agreement) for so long as CSFB Plan Partner has the right under the Metaldyne Shareholders Agreement to appoint a director to the Board of Directors of Metaldyne; provided, that upon MCLLC and its subsidiaries ceasing to own at least 20% of the outstanding shares of Common Stock owned by MCLLC immediately following the Transactions (as adjusted for Adjustments), CSFB Plan Partner shall no longer have the right to designate one director to the Board of Directors of the Company;

all of which persons shall hold office subject to their earlier removal in accordance with clause (iii) below, the Bylaws of the Company and applicable corporate law, until their respective successors shall have been elected and shall have qualified;

          (iii) the removal from the Board of Directors (with or without cause) of any director elected in accordance with clause (ii) above upon the written request of the Shareholders that designated such director; and

          (iv) upon any vacancy in the Board of Directors as a result of any individual designated as provided in clause (ii) above ceasing to be a member of the Board of Directors whether by resignation or otherwise, the election to the Board of Directors as promptly as possible of an individual designated by the Shareholders that designated such individual; provided that MCLLC and CSFB Plan Partner will consult with Sponsor prior to designating a replacement.

                    (b) The parties hereto agree to cause the Company’s Board of Directors to appoint at least one MCLLC Director to each decision-making committee of the Board and to cause at least one MCLLC Director to be nominated to the board of each subsidiary of the

Company to the extent the composition of such boards is substantially identical to the composition of the Company’s Board of Directors.

                    (c) The Company agrees to provide customary directors’ liability insurance.

                    (d) For so long as MCLLC owns at least 20% of the shares of Common Stock owned by MCLLC immediately following the Transactions (as adjusted for Adjustments), the Company shall not (a) make any material amendments or changes to its certificate of incorporation or bylaws without MCLLC’s prior written consent (which consent shall not be unreasonably withheld) or (b) liquidate, dissolve or wind-up its affairs without MCLLC’s prior written consent (which consent shall not be unreasonably withheld).

                    SECTION 4.07. Transaction with Affiliates. Without the consent of Shareholders (other than Sponsor and its Affiliates) owning a majority of the shares of Common Stock held by such Persons, for so long as Sponsor directly or indirectly beneficially owns thirty-five percent (35%) or more of the outstanding shares of Common Stock, the Company and its subsidiaries will not enter into, or suffer to exist, any transaction with Sponsor or any of its Affiliates (excluding Metaldyne and its subsidiaries) involving payments or other consideration in excess of $1.0 million. The foregoing restrictions will not apply to (a) the payment of annual monitoring fees to Sponsor in an amount not to exceed $4.0 million plus reimbursement of out-of-pocket expenses incurred by Sponsor in connection with the advisory services provided to the Company for the first year after the date hereof; (b) the payment to Sponsor of advisory fees and out-of-pocket expense reimbursement in connection with an acquisition, divestiture or financing by the Company or any of its subsidiaries (but excluding sales and purchases of personal property in the ordinary course of business) provided that such fees shall be in an amount equal to 1% of the aggregate value of such transaction; (c) fees payable to Sponsor in connection with the Transactions and reimbursement of out-of-pocket expenses incurred by Sponsor in connection with the Transactions; (d) transactions involving the sale, purchase or lease of goods or services in the ordinary course of business and on an arm’s-length basis between or among the Company or any of its subsidiaries and portfolio companies of Sponsor; (e) transactions between or among the Company or any of its subsidiaries; (f) issuances of Capital Stock to Sponsor and its Affiliates pursuant to, and in compliance with, Section 4.05; (g) transactions approved by the disinterested members of the Board of Directors of the Company (it being understood that a disinterested board member is one who does not have a direct or indirect material interest in the transaction to be voted on); (h) transactions pursuant to or contemplated by the TriMas Purchase Agreement; and (i) any transaction as to which the Company has received an opinion from an independent investment banking or other qualified firm that the transaction is fair to the Company from a financial point of view; provided that such firm shall be selected by the chief executive officer of MCLLC. Notwithstanding the foregoing, the benefits of this Section 4.07 shall terminate

upon MCLLC and its subsidiaries ceasing to own at least 20% of the shares of Common Stock owned by MCLLC immediately following the Transactions (as adjusted for Adjustments).

ARTICLE V

REGISTRATION RIGHTS

                    SECTION 5.01. Company Registration.

                    (a) Right to Piggyback on Registration of Stock. Subject to Section 5.01(c), if at any time or from time to time the Company proposes to register the Common Stock under the 1933 Act in connection with a public offering of such Common Stock on any form other than Form S-4 or Form S-8 or any similar successor forms or another form used for a purpose similar to the intended use for such forms (a “Piggyback Registration”), whether for its own account or for the account of one or more shareholders of the Company, the Company shall each such time promptly give each Shareholder written notice of such determination; provided, however, that such notice of a Piggyback Registration shall be given at least ten (10) business days prior to the earlier of the anticipated effective date of such Piggyback Registration or (y) the commencement of formal selling efforts by any underwriter in the case of an underwritten offering. Upon the written request of any Shareholder (the “Piggyback Holder”) given within eight (8) business days after the providing of any such notice by the Company, the Company shall use its best efforts to cause to be registered under the 1933 Act all of the Registrable Securities held by such Shareholder that the Shareholder has requested to be registered; provided, however, that if, at any time after giving written notice of its intention to register any securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration of such securities, the Company may, at its election, give written notice of such determination to each Piggyback Holder and (i) in the case of a determination not to register, shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not from any obligation of the Company to pay the registration expenses in connection therewith); and (ii) in the case of a determination to delay registering, shall be permitted to delay registering any Registrable Securities for the same period as the delay in registering such other securities. No registration effected under this Section 5.01 shall relieve the Company of its obligation to effect any registration upon demand under Section 5.02. The registration rights contained in Section 5.01 may be assigned to any Transferee or Permitted Transferee.

                    (b) Selection of Underwriters. If any Piggyback Registration involves an underwritten offering, the Company shall have sole discretion in the selection of any underwriter or underwriters to manage such Piggyback Registration.

                    (c) Priority on Piggyback Registrations. In the event that the Piggyback Registration includes an underwritten offering, the Company shall so advise the Shareholders as part of the written notice given pursuant to Section 5.01(a) and the registration rights provided in Section 5.01(a) shall be subject to the condition that if the managing underwriter or underwriters of a Piggyback Registration advise the Company in writing (a copy of which shall be provided to the applicable Shareholders) that in its opinion the number of Registrable Securities proposed to be sold in such Piggyback Registration exceeds the number which can be sold, and would materially adversely affect the price at which the Registrable Securities are to be sold, in such offering, the Company (or the Shareholders, as the case may be) will include in such registration only the number of Registrable Securities which, in the opinion of such underwriter or underwriters can be sold in such offering without such material adverse effect. The Registrable Securities so included in such Piggyback Registration shall be apportioned (i) first, either (x) subject to the rights of MCLLC set forth in the proviso to this Section 5.01(c), in a case including a primary registration on behalf of the Company, to any shares of Common Stock that the Company proposes to sell, or (y) in the case of a secondary registration on behalf of any person exercising demand registration rights, pro rata among the Holders on the basis of the number of shares of Common Stock to be registered pursuant to such demand registration (except to the extent otherwise provided in Section 5.02), (ii) second, shares held by MCLLC (in the event MCLLC ceases to be a Holder), (iii) third, pro rata among the Shareholders (other than MCLLC), if any, not included under clause (i) and (iv) fourth, pro rata among other shares included in such Piggyback Registration, in each case according to the total number of shares of the Common Stock requested for inclusion by said selling stockholders, or in such other proportions as shall mutually be agreed to among such selling stockholders; provided, however that, in the event of any primary registration on behalf of the Company, 50% of the Registrable Securities to be apportioned to the Piggyback Holders shall be apportioned to MCLLC to the extent MCLLC is a Piggyback Holder.

                    SECTION 5.02.Demand Registration Rights.

                    (a) Right to Demand. At any time after a Triggering Event, the Demand Holders may, individually or collectively, (x) make a written request, which request will specify the aggregate number of Registrable Securities to be registered and will also specify the intended methods of disposition thereof (the “Request Notice”) to the Company for registration with the Commission under and in accordance with the provisions of the 1933 Act of all or part of the Registrable Securities then owned by Demand Holders (a “Secondary Demand Registration”) or (y) make a written request, requesting that the Company register shares of Common Stock on a primary basis and consummate an Initial Public Offering (the “IPO Primary Demand” and together with the Secondary Demand Registration, a “Demand Registration”); provided that the Company may, if its Board of Directors so determines in the exercise of its reasonable, good faith judgment that due to a pending or contemplated acquisition or disposition or public offering or other material event involving the Company it would be in-

advisable to effect such Demand Registration at such time, the Company may, upon providing the Demand Holders written notice (the “Delay Notice”), defer, postpone or suspend such Demand Registration for a single period with respect to such Demand Registration not to exceed one hundred thirty-five (135) days. Upon receipt by the Company of a request (a “Demand Request”) to effect a Demand Registration the Company will within 10 business days after the receipt of such notice, notify each other Demand Holder of such request and such other Demand Holder(s) shall have the option to include its Registrable Securities in such Demand Registration pursuant to this Section 5.02. Subject to Section 5.02(g), the Company will register all other Registrable Securities which the Company has been requested to register by such other Demand Holders which still have the right to make a Request Notice pursuant to Section 5.02 hereof (each an “Incidental Demand Holder”) pursuant to this Section 5.02 by written request given to the Company by such holders within eight (8) business days after the giving of such written notice by the Company to such other Demand Holders. The Company shall not be obligated to maintain a registration statement pursuant to a Demand Registration effective for more than (x) ninety (90) days or (y) such shorter period when all of the Registrable Securities covered by such registration statement have been sold pursuant thereto (the “Effectiveness Period”). Notwithstanding the foregoing, the Company shall not be obligated to effect more than one Demand Registration in any 180-day period. Upon any such request for a Demand Registration, the Company will deliver any notices required by Section 5.01 and 5.02 and thereupon the Company will, subject to Section 5.01(c) and 5.02(f) hereof use its best efforts to effect the prompt registration under the 1933 Act of;

          (i) the Registrable Securities which the Company has been so requested to register by Demand Holders as contained in the Request Notice, and

          (ii) all other Registrable Securities which the Company has been requested to register by the Piggyback Holders and Incidental Demand Holders,

all to the extent required to permit the disposition of the Registrable Securities so to be registered in accordance with the intended method or methods of disposition of each seller of such Registrable Securities.

                    (b) Demand Conditions. Notwithstanding anything herein to the contrary, a Demand Holder will not be permitted to deliver a Request Notice prior to a Qualifying Public Equity Offering unless the Request Notice relates to an underwritten public offering. Such Demand Holder and the Company shall consult with one another and a nationally recognized investment banking firm selected by the Company to determine whether or not the most probable price to public for an initial public offering of Common Stock would be a per share price (the “Target Price”) that is in excess of $20.00 per share (as adjusted by the Adjustments). The Company shall not be obligated to proceed if the price to public is expected to be or is

less than the Target Price. All of the requirements referred to herein for a Request Notice prior to a Qualifying Public Equity Offering are referred to as the “Demand Conditions”.

                    (c) Number of Demand Registrations. The Company shall not be required to prepare and file a registration statement pursuant to this Section 5.02 if the Request Notice relates to shares of Common Stock held by such Demand Holder having a value of less than $40,000,000. In addition, the Company will not be required to effect more than three registrations pursuant to this Section 5.02 on behalf of MCLLC and its Direct Permitted Transferees provided, that MCLLC shall be afforded an additional Demand Registration if it has made an IPO Primary Demand. Sponsor and its Affiliates will be entitled to an unlimited number of Demand Registrations. It is hereby acknowledged and agreed by the parties that any Registrable Securities included in a registration statement on behalf of an Incidental Demand Holder will not count as a Demand Registration for such Incidental Demand Holder. In connection with a Demand Registration by more than one Demand Holder or by a Demand Holder and Incidental Demand Holders, such Demand Holders and Incidental Demand Holders shall elect one such Holder to act as representative (the “DH Representative”) in connection with such Demand Registration and the Company shall only be obligated to communicate with such DH Representative in connection with such Demand Registration. The Holders shall give the DH Representative any and all necessary powers of attorneys needed for the DH Representative to act on their behalf.

                    (d) Revocation. Holders of a majority in number of the Registrable Securities to be included in a registration statement pursuant to this Section 5.02 may, at any time prior to the effective date of the registration statement relating to such Demand Registration, acting through their DH Representative revoke such request by providing a written notice thereof to the Company. The Holders of Registrable Securities who revoke such request shall reimburse the Company for all its expenses incurred in the preparation, filing and processing of the registration statement. If pursuant to the terms of this Section 5.02(d), the Holders reimburse the Company for its reasonable expenses incurred in the preparation, filing and processing of any registration statement requested and subsequently revoked by such Holders, the attempted registration by such requested and subsequently revoked registration statement shall not be deemed to be a Demand Registration. Notwithstanding the foregoing, the Holders of a majority in number of the Registrable Securities to be included in a registration statement pursuant to this Section 5.02 may, at any time within five days after receipt of any Delay Notice acting through their DH Representative revoke such request by providing written notice thereof to the Company and the attempted Demand Registration shall not be deemed to be a Demand Registration, notwithstanding that such Holders shall not reimburse the Company for any expenses incurred in the preparation, filing and processing of any Registration Statement.

                    (e) Effective Registration. A registration will not count as a Demand Registration (i) if a Demand Holder determines in its good faith judgment to withdraw the pro-

posed registration of any Registrable Securities requested to be registered by such Demand Holder (x) due to marketing or regulatory reasons subject to such Holder reimbursing the Company for its expenses in accordance with Section 5.02(d) above, or (y) due to a material adverse change in the Company (other than as a result of any action by such Demand Holder); (ii) if such registration is interfered with by any stop order, injunction or other order or requirement of the Commission or other governmental agency or court for any reason (other than as a result of any action by the Holder) and the Company fails to promptly have such stop order, injunction or other order or requirement removed, withdrawn or resolved to the Holder’s satisfaction; or (iii) the conditions to closing specified in the underwriting agreement or purchase agreement entered into in connection with the registration relating to any such demand are not satisfied (other than as a result of a default or breach thereunder by the relevant Holder).

                    (f) Selection of Underwriters. If any of the Registrable Securities covered by a Demand Registration are to be sold in an underwritten offering, the Company will have the right to select the managing underwriter(s) to administer the offering.

                    (g) Priority on Demand Registrations. If the managing underwriter or underwriters of a Secondary Demand Registration advise the Company in writing that in its or their opinion the number of Registrable Securities proposed to be sold in such Secondary Demand Registration exceeds the number which can be sold, or adversely affects the price at which the Registrable Securities are to be sold, in such offering (the “Underwriter Cutback”), the Company will include in such registration only the number of Registrable Securities which, in the opinion of such underwriter or underwriters, can be sold in such offering without such material adverse effect. To the extent such Secondary Demand Registration includes Registrable Securities of more than one Holder, the Registrable Securities so included in such Secondary Demand Registration shall be apportioned (i) first, pro rata among the Demand Holders and any Incidental Demand Holders based upon the number of shares of Common Stock owned by each such Holder at the date of determination and (ii) second, pro rata among other shares of Common Stock included in such Secondary Demand Registration; provided, however that after an Initial Public Offering if MCLLC is a Demand Holder with respect to such Secondary Demand Registration, then MCLLC will be able to include in such registration in priority (such priority, the “MCLLC Priority”) to all Shareholders as many Registrable Securities as possible subject to the Underwriter Cutback.

                    (h) Assignability of Demand Registration Rights. The rights offered a Shareholder pursuant to Section 5.02 are only assignable to a Direct Permitted Transferee.

                    (i) Company Preemption Right. Notwithstanding anything herein to the contrary, if at any time a Holder shall request a Secondary Demand Registration, the Company may elect at that time to effect an underwritten primary offering by the Company (in which

case the applicable demand will not count as a Demand Registration) if, in the good faith judgment of the Company’s Board of Directors, it would be in the best interests of the Company to access the public market to raise equity capital in order to (i) finance an acquisition or investment or (ii) enhance the Company’s capital structure, liquidity or financial position. If the Company elects to effect a primary registration after receiving such a request for a Secondary Demand Registration, the Company will give prompt written notice (and in any event within 45 days after receiving such a request for a Demand Registration) to all Holders of its intention to effect such a registration and shall afford the Holders rights to Piggyback Registration in accordance with Section 5.01 hereof.

                    SECTION 5.03. Registration Procedures. It shall be a condition precedent to the obligations of the Company and any underwriter or underwriters to take any action pursuant to this Article V that the Shareholders requesting inclusion in any Piggyback Registration or Demand Registration (a “Registration”) shall furnish to the Company such information regarding them, the Registrable Securities held by them, the intended method of disposition of such Registrable Securities, and such agreements regarding indemnification, disposition of such securities and other matters referred to in this Article V as the Company shall reasonably request and as shall be required in connection with the action to be taken by the Company. With respect to any Registration which includes Registrable Securities held by a Shareholder, the Company will, subject to Sections 5.01 and 5.02 promptly:

          (a) Prepare and file with the Commission a registration statement on the appropriate form prescribed by the Commission and use its best efforts to cause such registration statement to become effective as soon as practicable thereafter; provided that the Company shall not be obligated to maintain such registration effective for a period longer than the Effectiveness Period; provided further that before filing a registration statement or prospectus or any amendments or supplements thereto, including documents incorporated by reference after the initial filing of the registration statement, the Company will furnish to the holders of the Registrable Securities covered by such registration statement and the underwriter or underwriters, if any, copies of or drafts of all such documents proposed to be filed, including documents incorporated by reference in the Prospectus and, if required by such holders, the exhibits incorporated by reference, at least three (3) business days prior thereto, which documents will be subject to the reasonable review of such holders and underwriters. Holders of Registrable Securities covered by such registration statement will have the opportunity to object to any information pertaining to such holders that is contained therein and the Company will make the corrections reasonably requested by such holders with respect to such information prior to filing any registration statement or amendment thereto or any prospectus or any supplement thereto; provided, however, that the Company will not file any registration statement or amendment thereto or any prospectus or any supplement thereto or any documents required to be incorporated by reference therein to

which holders of a majority of the Registrable Securities covered by such registration statement or the underwriters, if any, shall reasonably object;

          (b) Prepare and file with the Commission such amendments and post-effective amendments to such registration statement and any documents required to be incorporated by reference therein as may be necessary to keep the registration statement effective for a period of not less than the Effectiveness Period (but not prior to the expiration of the time period referred to in Section 4(3) of the 1933 Act and Rule 174 thereunder, if applicable); cause the prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the 1933 Act; and comply with the provisions of the 1933 Act applicable to it with respect to the disposition of all Registrable Securities covered by such registration statement during the applicable period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement or supplement to the prospectus;

          (c) Furnish to such Shareholder, without charge, such number of conformed copies of the registration statement and any post-effective amendment thereto, as such Shareholder may reasonably request, and such number of copies of the prospectus (including each preliminary prospectus) and any amendments or supplements thereto, and any documents incorporated by reference therein as the Shareholder or underwriter or underwriters, if any, may request in order to facilitate the disposition of the securities being sold by the Shareholder (it being understood that the Company consents to the use of the prospectus and any amendment or supplement thereto by the Shareholder covered by the registration statement and the underwriter or underwriters, if any, in connection with the offering and sale of the securities covered by the prospectus or any amendments or supplements thereto);

          (d) Notify such Shareholder, at any time when a prospectus relating thereto is required to be delivered under the 1933 Act, when the Company becomes aware of the happening of any event as a result of which the prospectus included in such registration statement (as then in effect) contains any untrue statement of material fact or omits to state a material fact necessary to make the statements therein (in the case of the prospectus or any preliminary prospectus, in light of the circumstances under which they were made) not misleading and, as promptly as practicable thereafter, prepare and file with the Commission and furnish a supplement or amendment to such prospectus so that, as thereafter delivered to the investors of such securities, such prospectus will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

          (e) In the case of an underwritten offering, enter into such customary agreements (including underwriting agreements in customary form) and make members of senior management of the Company available on a basis reasonably requested by the underwriters to participate in, “road show” and other customary marketing activities (including one-on-one meetings with prospective purchasers of the Registrable Securities) and cause to be delivered to the underwriters reasonable opinions of counsel to the Company in customary form, covering such matters as are customarily covered by opinions for an underwritten public offering as the underwriters may reasonably request and addressed to the underwriters;

          (f) Make available, for inspection by any seller of Registrable Securities, any underwriter participating in any disposition pursuant to a registration statement, and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent that are necessary to be reviewed by such person in connection with the preparation of such registration statement;

          (g) If requested, cause to be delivered, immediately prior to the effectiveness of the registration statement (and, in the case of an underwritten offering, at the time of delivery of any Registrable Securities sold pursuant thereto), letters from the Company’s independent certified public accountants addressed to each selling Shareholder (unless such selling Shareholder does not provide to such accountants the appropriate representation letter required by rules governing the accounting profession) and each underwriter, if any, stating that such accountants are independent public accountants within the meaning of the 1933 Act and the applicable rules and regulations adopted by the Commission thereunder, and otherwise in customary form and covering such financial and accounting matters as are customarily covered by letters of the independent certified public accountants delivered in connection with primary or secondary underwritten public offerings, as the case may be;

          (h) Provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of the registration statement;

          (i) Use its best efforts to cause all securities included in such registration statement to be listed, by the date of the first sale of securities pursuant to such registration statement, on any national securities exchange, quotation system or other market on which the Common Stock is then listed or proposed to be listed by the Company, if any;

          (j) Make generally available to its security holders an earnings statement, which need not be audited, satisfying the provisions of Section 11(a) of the 1933 Act as soon as reasonably practicable after the end of the twelve (12)-month period beginning with the first month of the Company’s first fiscal quarter commencing after the effective date of the registration statement, which statement shall cover said twelve (12)-month period;

          (k) After the filing of a registration statement, (i) promptly notify each Shareholder holding Registrable Securities covered by such registration statement of any stop order issued or, to the Company’s knowledge, threatened by the Commission and of the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction and (ii) take all reasonable actions to obtain the withdrawal of any order suspending the effectiveness of the registration statement or the qualification of any Registrable Securities at the earliest possible moment; (l) Subject to the time limitations specified in paragraph (b) above, if requested by the managing underwriter or underwriters or such Shareholder, promptly incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or underwriters or the Shareholder reasonably requests to be included therein, including, without limitation, with respect to the number of shares being sold by the Shareholder to such underwriter or underwriters, the purchase price being paid therefor by such underwriter or underwriters and with respect to any term of the underwritten offering of the securities to be sold in such offering; and make all required filings of such prospectus supplement or post-effective amendment as soon as practicable after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment;

          (l) Subject to the time limitations specified in paragraph (b) above, if requested by the managing underwriter or underwriters or such Shareholder, promptly incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or underwriters or the Shareholder reasonably requests to be included therein, including, without limitation, with respect to the number of shares being sold by the Shareholder to such underwriter or underwriters, the purchase price being paid therefor by such underwriter or underwriters and with respect to any term of the underwritten offering of the securities to be sold in such offering; and make all required filings of such prospectus supplement or post-effective amendment as soon as practicable after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment;

          (m) As promptly as practicable after filing with the Commission of any document which is incorporated by reference into a registration statement, deliver a copy of such document to such Shareholder;

          (n) On or prior to the date on which the registration statement is declared effective, use its best efforts to register or qualify, and cooperate with such Shareholder, the underwriter or underwriters, if any, and their counsel in connection with the registration or qualification of, the securities covered by the registration statement for offer and sale under the securities or blue sky laws of each state and other jurisdiction of the United States as the Shareholder or managing underwriter or underwriters, if any, requests in writing, to use its best efforts to keep each such registration or qualification effective, including through new filings, or amendments or renewals, during the Effectiveness Period and do any and all other acts or things necessary or advisable to

enable the disposition in all such jurisdictions of the Registrable Securities covered by the applicable registration statement; provided that the Company will not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject;

          (o) Cooperate with such Shareholder and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing securities to be sold under the registration statement, and enable such securities to be in such denominations and registered in such names as the Shareholder or the managing underwriter or underwriters, if any, may request, as applicable; and

          (p) Use its best efforts to cause the securities covered by the registration statement to be registered with or approved by such other governmental agencies, authorities or self-regulatory bodies within the United States as may be necessary to enable the seller or sellers thereof or the underwriter or underwriters, if any, to consummate the disposition of such Registrable Securities.

                    At all times after an Initial Public Offering, the Company shall file all reports required to be filed by it under the 1933 Act and the 1934 Act and the rules and regulations adopted by the Commission thereunder, and take such further action as any Shareholders may reasonably request, all to the extent required to enable such Shareholders to be eligible to sell Registrable Securities pursuant to Rule 144 of the 1933 Act (or any similar rule then in effect).

                    The Shareholders, upon receipt of any notice from the Company of the happening of any event of the kind described in subsection (d) of this Section 5.03, will forthwith discontinue disposition of the securities until the Shareholders’ receipt of the copies of the supplemented or amended prospectus contemplated by subsection (d) of this Section 5.03 or until it is advised in writing (the “Advice”) by the Company that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings which are incorporated by reference in the prospectus, and, if so directed by the Company, each Shareholder will, or will request the managing underwriter or underwriters, if any, to, deliver, to the Company (at the Company’s expense) all copies, other than permanent file copies then in such Shareholder’s possession, of the prospectus covering such securities current at the time of receipt of such notice. In the event the Company shall give any such notice, the time periods mentioned in subsections (a), (b) and (n) of this Section 5.03 shall be extended by the number of days during the period from and including any date of the giving of such notice to and including the date when each seller of securities covered by such registration statement shall

have received the copies of the supplemented or amended prospectus contemplated by subsection (d) of this Section 5.03 hereof or the Advice.

                    SECTION 5.04. Registration Expenses. (a) Subject to Section 5.02(d), in the case of any Registration, the Company shall bear all expenses incident to the Company’s performance of or compliance with Sections 5.01, 5.02 and 5.03 of this Agreement, including, without limitation, all Commission and stock exchange or National Association of Securities Dealers, Inc. registration and filing fees and expenses, fees and expenses of compliance with securities or blue sky laws (including, without limitation, reasonable fees and disbursements of counsel in connection with blue sky qualifications of the Registrable Securities), rating agency fees, printing expenses, messenger, telephone and delivery expenses, fees and disbursements of counsel for the Company and all independent certified public accountants and any fees and disbursements of underwriters customarily paid by issuers or sellers of securities (but not including any underwriting discounts or commissions, or transfer taxes, if any, attributable to the sale of Registrable Securities by a Piggyback Holder or Holder or fees and expenses of more than one counsel representing the Shareholders selling Registrable Securities under such Registration).

                    (b) In connection with each registration initiated hereunder (whether a Demand Registration or a Piggyback Registration), the Company shall reimburse the holders of Registrable Securities covered by such registration or sale for the reasonable fees and disbursements of one law firm chosen by the holders of a majority of the number of shares of Registrable Securities included in such registration.

                    (c) The obligation of the Company to bear the expenses described in Section 5.04(a) and to reimburse the holders for the expenses described in Section 5.04(b) shall apply irrespective of whether a registration, once properly demanded, if applicable, becomes effective, is withdrawn or suspended, or is converted to another form of registration and irrespective of when any of the foregoing shall occur; provided, however, that the expenses for any registration statement withdrawn pursuant to 5.02(d) prior to its effectiveness at the request of a Holder (unless withdrawn following and due to a Delay Notice), any registration statement withdrawn solely at the request of a Holder, or any supplements or amendments to a registration statement or prospectus resulting from a misstatement furnished to the Company by a Holder, shall be borne by such Holder.

                    SECTION 5.05.Indemnification.

                    (a) Indemnification by the Company. The Company agrees to indemnify and hold harmless each Shareholder, its officers, directors, Affiliates and agents and each Person who controls (within the meaning of the 1933 Act or the 1934 Act) the Shareholder, including, without limitation any general partner or manager of any thereof, against all losses, claims, damages, liabilities and expenses (including reasonable counsel fees and disburse-

ments) arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any registration statement, prospectus or preliminary prospectus, or any amendment thereof or supplement thereto, in which such Shareholder participates in an offering of Registrable Securities or in any document incorporated by reference therein or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus or any preliminary prospectus, in light of the circumstances under which they were made) not misleading, except insofar as the same are made in reliance on and in conformity with any information with respect to such Shareholder furnished in writing to the Company by such Shareholder expressly for use therein; provided, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Shareholder from whom the Person asserting such loss, claim, damage or liability purchased the securities if it is determined that such loss, claim, damage or liability was caused by such Shareholder’s failure to deliver to such Shareholder’s immediate purchaser a current copy of the prospectus (if the current copy of the prospectus was required by applicable law to be so delivered) after the Company has furnished such Shareholder with a sufficient number of copies of such prospectus. The Company will also indemnify underwriters (as such term is defined in the 1933 Act), their officers and directors and each Person who controls such underwriters (within the meaning of the 1933 Act) to the same extent as provided above with respect to the indemnification of the Shareholders.

                    (b) Indemnification by the Shareholders. In connection with any registration statement in which a Shareholder is participating, each such Shareholder will furnish to the Company in writing such information and affidavits with respect to such Shareholder as the Company reasonably requests for use in connection with any registration statement or prospectus covering the Registrable Securities of such Shareholder and to the extent permitted by law agrees to indemnify and hold harmless the Company, its directors, officers and agents and each Person who controls (within the meaning of the 1933 Act or the 1934 Act) the Company, against any losses, claims, damages, liabilities and expenses arising out of or based upon any untrue statement of a material fact or any omission to state a material fact required to be stated therein or necessary to make the statements in the registration statement or prospectus or preliminary prospectus (in the case of the prospectus or preliminary prospectus, in light of the circumstances under which they were made) not misleading, to the extent, but only to the extent, that such untrue statement or omission is made in reliance on and in conformity with the information or affidavit with respect to such Shareholder so furnished in writing by such Shareholder expressly for use in the registration statement or prospectus; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Shareholders and the liability of each such Shareholder shall be in proportion to and limited to the net amount received by such Shareholder from the sale of Registrable Securities pursuant to such registration statement in accordance with the terms of this Agreement. The indemnity agreement contained in this Section 5.05 shall not apply to amounts paid in settlement of any such

loss, claim, damage, liability, action or proceeding if such settlement is effected without the consent of such Shareholder (which consent shall not be unreasonably withheld or delayed). The Company and the holders of the Registrable Securities hereby acknowledge and agree that, unless otherwise expressly agreed to in writing by such holders, the only information furnished or to be furnished to the Company for use in any registration statement or prospectus relating to the Registrable Securities or in any amendment, supplement or preliminary materials associated therewith are statements specifically relating to (a) transactions or the relationship between such holder and its Affiliates, on the one hand, and the Company, on the other hand, (b) the beneficial ownership of shares of Common Stock by such holder and its Affiliates, (c) the name and address of such holder and (d) any additional information about such holder or the plan of distribution (other than for an underwritten offering) required by law or regulation to be disclosed in any such document.

                    (c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder will (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest may exist between such indemnified and indemnifying parties with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. The failure to so notify the indemnifying party shall not relieve the indemnifying party from any liability hereunder with respect to the action, except to the extent that such indemnifying party is materially prejudiced by the failure to give such notice; provided, however, that any such failure shall not relieve the indemnifying party from any other liability which it may have to any other party. No indemnifying party in the defense of any such claim or litigation, shall, except with the consent of such indemnified party, which consent shall not be unreasonably withheld, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party there may be one or more legal or equitable defenses available to such indemnified party which are in addition to or may conflict with those available to any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the reasonable fees and expenses of such additional counsel or counsels; provided, however, that such number of additional counsel must be reasonably acceptable to the indemnifying party.

                    (d) Contribution. If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) of this Section 5.05 is unavailable to an indemnified party as contemplated by the preceding paragraphs (a) and (b) of this Section 5.05, then the indemnify-

ing party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect not only the relative benefits received by the indemnified party and the indemnifying party, but also the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. In no event shall the liability of any selling Shareholder be greater in amount than the amount of net proceeds received by such Shareholder upon such sale or the amount for which such indemnifying party would have been obligated to pay by way of indemnification if the indemnification provided in paragraph (b) of this Section 5.05 had been available.

                    SECTION 5.06. 1934 Act Reports. The Company agrees that at all times after it has filed a registration statement pursuant to the requirements of the 1933 Act relating to any class of equity securities of the Company, it will use its best efforts to file in a timely manner all reports required to be filed by it pursuant to the 1934 Act to the extent the Company is required to file such reports. Notwithstanding the foregoing, the Company may deregister any class of its equity securities under Section 12 of the 1934 Act or suspend its duty to file reports with respect to any class of its securities pursuant to Section 15(d) of the 1934 Act if it is then permitted to do so pursuant to the 1934 Act and rules and regulations thereunder.

                    SECTION 5.07. Holdback Agreements. (a) Whenever the Company proposes to register any of its equity securities under the 1933 Act for its own account (other than on Form S-4 or S-8 or any similar successor form or another form used for a purpose similar to the intended use of such forms) or is required to use its best efforts to effect the registration of any Registrable Securities under the 1933 Act pursuant to Section 5.01 or 5.02, each holder of Registrable Securities agrees by acquisition of such Registrable Securities not to effect any sale or distribution, including any sale pursuant to Rule 144 under the 1933 Act, or to request registration under Section 5.02 of any Registrable Securities within 10 days prior to and 90 days (unless advised by the managing underwriter that a longer period, not to exceed 180 days, is required, or such shorter period as the managing underwriter for any underwritten offering may agree) after the effective date of the registration statement relating to such registration, except as part of such registration or unless in the case of a private sale or distribution, the transferee agrees in writing to be subject to this Section 5.07. If requested by such managing underwriter, each holder of Registrable Securities agrees to execute a holdback agreement, in customary form, consistent with the terms of this Section 5.07(a). Notwithstanding the foregoing, no Shareholder will be restricted from selling any Registrable Securities if such Shareholder and its Affiliates beneficially own a number of shares of Common Stock as of such date of determination equal to less than five percent (5%) of the outstanding Common Stock.

                    (b) The Company agrees not to effect any sale or distribution of any of its equity securities or securities convertible into or exchangeable or exercisable for any of such

securities within the 10 days prior to and during the 90 days (unless advised by the managing underwriter that a longer period, not to exceed 180 days, is required, or such shorter period as the managing underwriter for any underwritten offering may agree) beginning on the effective date of any underwritten Demand Registration or any underwritten Piggyback Registration (except as part of such underwritten registration or pursuant to registrations on Form S-8 or S-4 or any successor forms thereto), except that such restriction shall not prohibit (i) grants of employee stock options or other issuances of Capital Stock pursuant to the terms of a Company employee benefit plan, issuances by the Company of Capital Stock pursuant to the exercise of such options or the exercise of any other employee stock options outstanding on the date hereof, (ii) the Company from issuing shares of Capital Stock in private placements pursuant to Section 4(2) of the 1933 Act or in connection with a strategic alliance, or (iii) the Company from publicly announcing its intention to issue, or actually issuing, shares of Capital Stock to shareholders of another entity as consideration for the Company’s acquisition of, or merger with, such entity. In addition, upon the request of the managing underwriter, the Company shall use its best efforts to cause each holder of its equity securities or any securities convertible into or exchangeable or exercisable for any of such securities whether outstanding on the date of this Agreement or issued at any time after the date of this Agreement (other than any such securities acquired in a public offering), to agree not to effect any such public sale or distribution of such securities during such period, except as part of any such registration if permitted, and to cause each such holder to enter into a similar agreement to such effect with the Company.

                    SECTION 5.08. Participation in Registrations. No Shareholder may participate in any Registration hereunder which is underwritten unless such Shareholder (a) agrees to sell its securities on the basis provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements, and (b) completes and executes all questionnaires, powers of attorney, underwriting agreements and other documents customarily required under the terms of such underwriting arrangements.

                    SECTION 5.09. Remedies. Each Shareholder shall have the right and remedy to have the provisions of Sections 5.01 and 5.02 specifically enforced by any court having jurisdiction in the event that the Company materially breaches such provisions, and the Company shall reimburse such Shareholder for the reasonable costs of and expenses for counsel for such Shareholder incurred in connection with such proceeding.

                    SECTION 5.10. Other Registration Rights.

                    SECTION 6.13. ERISA Matters. The Company agrees to give Sponsor certain board observation rights and consultation rights to the extent Sponsor does not have the ability to designate a Person to the Board of Directors of the Company and failure to have such board observation rights and consultation rights would cause Sponsor to have an ERISA Problem. For purposes of this Section 6.13, “ERISA Problem” means that the assets of Sponsor and its Affiliates would be considered “Plan Assets” within the meaning of 29 CFR 2510.3-101 due to the fact that Sponsor and its Affiliates do not have such rights.

                    SECTION 6.14. Regulatory Cooperation.

Such reasonable action to be taken may include the Company’s authorization of one or more new classes of non-voting common stock that is otherwise substantially identical to the Common Stock then owned by such Shareholder and the amendment of the Company’s certificate of incorporation or any other documents or instruments executed in connection with the shares held by such Shareholder. Such Shareholder shall give written notice to the Company and the other Shareholders of any such determination and the actions necessary to comply with such Regulatory Requirement, and the Company and such other Shareholders shall take all reasonably necessary steps to comply with such determination as expeditiously as possible.

                    SECTION 6.15. Publicity. None of the parties hereto shall issue any press release or make any public disclosure regarding the transactions contemplated hereby unless such press release or public disclosure shall be approved by those parties mentioned in such press release or public disclosure in advance. Notwithstanding the foregoing, each of the parties hereto may, in documents required to be filed by it with the Commission or other regulatory bodies, make such statements with respect to the transactions contemplated hereby as each may be advised by counsel is legally necessary or advisable, and may make such disclosure as it is advised by its counsel is required by law.

                    SECTION 6.16. MCLLC Securities. Notwithstanding clause (iii) of the definition of “Permitted Transferee”, MCLLC or any controlled Affiliate of MCLLC (including any wholly-owned subsidiary of MCLLC) may issue any security (the “Convertible Security”) which is convertible or exchangeable into the Common Stock, provided that concurrently with such issuance the recipient of such Convertible Security executes a Joinder Agreement agreeing to be bound by the terms of this Shareholders Agreement as a Shareholder to the extent that the Convertible Security is converted or exchanged into the Common Stock and agrees that no subsequent Transfers of such Convertible Security shall be effected unless such subsequent transferee executes a Joinder Agreement agreeing to be bound by the terms of this Shareholders Agreement as a Shareholder to the extent that the Convertible Security is converted or exchanged into the Common Stock.
