REGISTRATION RIGHTS

2.1 Investor Request for Registration.

(a) If, at any time after the expiration of six months following a Qualified IPO, the Company shall receive a written request from the Investors holding a majority of the Registrable Securities that the Company file a registration statement under the Securities Act covering the registration of Registrable Securities where the anticipated aggregate offering price, before deduction of underwriting discounts and commissions, of Registrable Securities to be sold by such Investors is at least $5,000,000, then the Company shall, within 10 days of the receipt thereof, give written notice of such request to all Investors and shall, subject to the limitations of subsection 2.1(b), use its commercially reasonable efforts to effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities which the Investors request to be registered within 20 days of the mailing of such notice by the Company in accordance with Section 6.7 hereof.

(b) If the Investors initiating the registration request hereunder (“Initiating Investors”) intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 2.1 and the Company shall include such information in the written notice referred to in subsection 2.1(a). The underwriter will be selected by a majority in interest of the Initiating Investors and shall be reasonably acceptable to the Company. In such event, the right of any Investor to include such Investor’s Registrable Securities in such registration shall be conditioned upon such Investor’s participation in such underwriting and the inclusion of such Investor’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Investors and such Investor) to the extent provided herein. All Investors proposing to distribute their securities through such underwriting shall (together with the Company as provided in Section 2.4(e)) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of this Section 2.1, if the underwriter advises the Initiating Investors in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Initiating Investors shall so advise all Investors of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated among all Investors thereof, including the Initiating Investors, in proportion (as nearly as practicable) to the amount of Registrable Securities of the Company owned by each Investor; provided, however, that the

number of Registrable Securities to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting.

(c) Notwithstanding the foregoing, if the Company shall furnish to the Initiating Investors a certificate signed by the President of the Company stating that, in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such registration statement to be filed or become effective at such time, the Company shall have the right to defer such filing for a period of not more than 90 days after receipt of the request of the Initiating Investors; provided, however, that the Company may not utilize this right more than once in any twelve-month period.

(d) In addition, the Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to this Section 2.1:

(i) If the Company delivers in good faith a written notice to the Initiating Investors within 10 days after receipt of the registration request from the Initiating Investors that the Company intends to file a registration statement for a public offering, then during the period commencing with the date of the giving of such notice, and ending 90 days thereafter;

(ii) During the period ending 180 days after the effective date of any registration statement pertaining to a public offering of the Company’s Common Stock; or

(iii) After the Company has effected two registrations pursuant to this Section 2.1 and such registrations have been declared effective.

(e) The Company shall provide notice to the Investors in the event that it intends to permit securities that are not Registrable Securities to be included in any registration statement filed pursuant to this Section 2.1. If, in respect of any underwritten offering pursuant to this Section 2.1, the underwriter advises the Investors that marketing factors require a limitation of the amount of securities to be underwritten, the number of Registrable Securities to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting.

(f) The Investors holding a majority of Registrable Securities may, at any time prior to the effective date of any registration statement, revoke such request by providing a written notice to the Company revoking such request. Any request made pursuant to this Section 2.1 so withdrawn shall not be counted for purposes of determining the number of requests for registration to which the holders of Registrable Securities are entitled pursuant to this Section 2, so long as the revoking Investors pay the Company’s reasonable expenses in connection with the preparation of such abandoned registration.

2.2 Company Registration.

(a) If (but without any obligation to do so) the Company proposes to register (including for this purpose a registration effected by the Company for securityholders other than the Investors) any of its equity securities under the Securities Act in connection with the public offering of such securities solely for cash (other than a registration statement on Form S-4 or S-8

or any successor forms thereto, any registration statement filed in connection with an exchange offer of securities solely to the Company’s existing security holders, or any registration statement filed in connection with a Qualified IPO (as to which Section 2.2(b) hereof shall govern)), the Company shall, at such time, promptly give each Investor written notice of such registration. Upon the written request of each Investor given within 20 days after mailing of such notice by the Company in accordance with Section 6.7 hereof, the Company shall, subject to the provisions of Section 2.7, use its commercially reasonable efforts to cause to be registered under the Securities Act all of the Registrable Securities that each such Investor has requested to be registered.

(b) If (but without any obligation to do so) the Company proposes to register its Common Stock under the Securities Act in order to effect a Qualified IPO, the Company shall, at least 30 days prior to the filing of any registration statement related to such Qualified IPO, give each Investor written notice of such registration. Upon the written request of any Investor given within 15 days after mailing of such notice by the Company in accordance with Section 6.7 hereof, the Company shall include in the Qualified IPO all of the Common Stock into which the Preferred Stock of such Investor indicated in such Investor’s written request is convertible at the occurrence of the Qualified IPO, on the same terms, including underwriting arrangements, as shares of Common Stock sold by the Company in the Qualified IPO are so included. The foregoing shall not limit the Company’s ability to abandon any proposed Qualified IPO at any time prior to the consummation thereof.

2.3 Form S-3 Registration.

(a) If, at any time after the expiration of six months following the initial public offering of the Company’s Common Stock, the Company shall receive a written request from any Investor or Investors that the Company file a registration on Form S-3 for a public offering of Registrable Securities, the Company will:

(i) promptly give written notice of the proposed registration to all other Investors; and

(ii) as soon as practicable, use its commercially reasonable efforts to effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Investors’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Investor or Investors joining such request as are specified in a written request given within 15 days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance, pursuant to this Section 2.3: (A) if Form S-3 is not available for such offering by the Investors; (B) if the Investors, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public (before deduction of any underwriters’ discounts or commissions) of less than $3,000,000; (C) if the Company shall furnish to the Investors a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such Form S-3 Registration to be effected at

such time, in which event the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than 90 days after receipt of the request of the Investor or Investors under this Section 2.3; provided, however, that the Company shall not utilize this right more than once in any twelve month period; (D) at any time that the Company has effected two registrations pursuant to this Section 2.3 in the preceding twelve month period and such registrations have been declared effective; or (E) if the Company delivers in good faith a written notice to the Investors requesting registration pursuant to this Section 2.3 within 10 days after receipt of such request that the Company intends to file a registration statement for a public offering, during the period commencing with the date of giving such notice and ending 90 days thereafter.

(b) Subject to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request of the Investors. Registrations effected pursuant to this Section 2.3 shall not be counted as demands for registration or registrations effected pursuant to Section 2.1.

(c) The Company shall provide notice to the Investors in the event that it intends to permit securities that are not Registrable Securities to be included in any registration statement filed pursuant to this Section 2.3. If, in respect of any underwritten offering pursuant to this Section 2.3, the underwriter advises the Investors that marketing factors require a limitation of the amount of securities to be underwritten, the number of Registrable Securities to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting.

(d) The Investors holding a majority of Registrable Securities may, at any time prior to the effective date of any registration statement, revoke such request by providing a written notice to the Company revoking such request, so long as the revoking Investors pay the Company’s reasonable expenses in connection with the preparation of such abandoned registration.

2.7 Underwriting Requirements.

(a) In connection with any offering involving an underwriting of shares of the Company’s capital stock (other than a Qualified IPO), the Company shall not be required under Section 2.2(a) to include any of the Investors’ Registrable Securities in such underwriting unless they accept the terms of the underwriting (which terms shall be reasonable and customary as to

the selling stockholders in such offering) as agreed upon between the Company and the underwriters selected by it (or by other persons entitled to select the underwriters), and then only in such quantity as the underwriters determine in their sole discretion will not jeopardize the success of the offering by the Company. If the total amount of securities, including Registrable Securities, requested by stockholders to be included in such offering (other than a Qualified IPO) exceeds the amount of securities sold by parties other than the Company that the underwriters determine in their sole discretion is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters determine in their sole discretion will not jeopardize the success of the offering (the securities so included to be apportioned pro rata among the selling stockholders according to the total amount of securities entitled to be included therein owned by each selling stockholder or in such other proportions as shall mutually be agreed to by such selling stockholders); provided, however, that the number of Registrable Securities to be included in any such underwriting shall not be reduced unless all securities that are not (i) Registrable Securities, (ii) owned by holders who exercised a right to request the registration in which the Investors are joining or (iii) offered by the Company are first entirely excluded from the underwriting. Notwithstanding the foregoing, in no event shall the amount of Registrable Securities held by all Investors included in the offering be reduced below 25% of the total number of securities included in such offering unless such offering is the Company’s initial public offering and such offering is not a Qualified IPO.

(b) In connection with a Qualified IPO, the Company shall not be required under Section 2.2(b) to include any of the Investors’ Common Stock in such underwriting unless they accept the terms of the underwriting (which terms shall be customary and reasonable as to the selling stockholders in the Qualified IPO) as agreed upon between the Company and the underwriters selected by it.

2.8 Indemnification.

(a) The Company will indemnify each Investor, each of its officers, directors and partners, members, stockholders, employees, agents (including such Investor’s legal counsel and independent accountants), and each person controlling such Investor within the meaning of Section 15 of the Securities Act, with respect to which registration, qualification or compliance has been effected pursuant to this Agreement, and each underwriter, if any, and each person who controls any underwriter within the meaning of Section 15 of the Securities Act, against all expenses, claims, losses, damages and liabilities (or actions in respect thereof, including any of the foregoing incurred in settlement of any litigation, arising out of or based on (i) any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or (ii) any violation by the Company of any rule or regulation promulgated under the Securities Act applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance and will reimburse each such Investor, each of its officers, directors and partners, members, stockholders, employees, agents and such Investor’s legal counsel and independent

accountants, and each person controlling such Investor, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action; provided that the Company will not be liable (a) to such Investor in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Investor and stated to be specifically for use therein, (b) to such Investor in respect of a sale of Registrable Securities by such Investor pursuant to a Shelf Registration, to the extent such claim, loss, damage, liability or expense arises out of or is based on the failure of such Investor to effectively cause the prospectus delivery requirement of the Securities Act to be satisfied, provided that the Company has complied with its obligations under Section 2.4(d) of this Agreement, or (c) to such underwriter in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such underwriter and stated to be specifically for use therein.

(b) Each Investor will, severally and not jointly, if Registrable Securities held by such Investor are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Company, each of its directors and officers, stockholders, employees and agents (including its legal counsel and independent accountants), each underwriter, if any, of the Company’s securities covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, and each other such Investor, each of its officers and directors and each person controlling such Investor within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, arising out of or based on the following (a “Violation”): (1) any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Investor and stated to be specifically for use therein, or (2) solely in respect of Registrable Securities sold by an Investor pursuant to a Shelf Registration, any failure by such Investor to effectively cause the prospectus delivery requirement of the Securities Act to be satisfied, provided that the Company has complied with its obligations under Section 2.4(d) of this Agreement. In the event of a Violation, such Investor will reimburse the Company, such Investors, such directors, officers, stockholders, employees and agents (including its legal counsel and independent accountants), underwriters or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action for which such Investor is obligated to provide indemnification pursuant to the foregoing; provided, however, that the obligations of such Investor under this Section 2.8(b) shall be limited to an amount

equal to the net proceeds (after expenses, discounts and commissions) received by such Investor holding Registrable Securities sold in the registered offering in which such Violation arose.

(c) Each party entitled to indemnification under this Section 2.8 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld), and the Indemnified Party may participate in such defense at such party’s expense; and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement, except to the extent, but only to the extent, that the Indemnifying Party’s ability to defend against such claim or litigation is materially adversely affected as a result of such failure to give notice. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, 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 to such claim or litigation.

(d) If the indemnification provided for in paragraphs (a) and (b) of this Section 2.8 is unavailable or insufficient to hold harmless an Indemnified Party under such paragraphs in respect of any losses, claims, damages or liabilities or actions in respect thereof referred to therein, then each Indemnifying Party shall in lieu of indemnifying such Indemnified Party contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages, liabilities or actions in such proportion as appropriate to reflect the relative fault of the Indemnifying Party, on the one hand, and the Indemnified Party, on the other, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or actions as well as any other relevant equitable considerations, including the failure to give any notice under paragraph (c) of this Section 2.8. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact relates to information supplied by the Indemnifying Party, on the one hand, or the Indemnified Party, on the other hand, and to the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Investors holding Registrable Securities participating in the relevant offering agree that it would not be just and equitable if contributions pursuant to this paragraph were determined by pro rata allocation (even if all of the Investors holding Registrable Securities participating in the relevant offering were treated as one entity for such purpose) or by any other method of allocation which did not take account of the equitable considerations referred to above in this paragraph. The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages, liabilities or action in respect thereof, referred to above in this paragraph, shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this paragraph, an Investor selling Registrable Securities shall not be required to contribute any amount in excess of the net proceeds (after expenses, discounts and commissions) received by such Investor selling Registrable Securities sold as contemplated herein. No person guilty of fraudulent misrepresentations (within the meaning of Section 11(f)

of the Securities Act), shall be entitled to contribution from any person who is not guilty of such fraudulent misrepresentation.

(e) The indemnification of underwriters provided for in this Section 2.8 shall be on such other terms and conditions as are at the time customary and reasonably required by such underwriters. In that event the indemnification of the Investors holding Registrable Securities in such underwriting shall at the sellers’ request be modified to conform to such terms and conditions.

2.9 Reports Under Securities Laws.

With a view to making available to the Investors the benefits of Rule 144 promulgated by the SEC under the Securities Act and any other rule or regulation of the SEC that may at any time permit an Investor to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to:

2.11 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of the Investors holding at least 66²/3% of the outstanding Registrable Securities, enter into any agreement with any holder or prospective holder of any securities of the Company other than a Permitted Holder that would grant such holder “piggyback” registration rights that would reduce the number of Registrable Securities includable by the Investors in a Company registration pursuant to Section 2.2(a) hereof.

5.2 Tag-Along Rights.

those regarding ownership of the shares being Transferred, authorization, good standing, no conflict with constituent documents and use of brokers.

This Agreement sets forth the entire understanding and agreement between the parties with respect to the transactions contemplated herein and supersedes and replaces any prior understanding, agreement or statement of intent, in each case written or oral, of any kind and every nature with respect hereto.

The waiver by any party hereto of a breach of any provision of this Agreement shall not operate or be construed as a further or continuing waiver of such breach or as a waiver of any other or subsequent breach. Except as otherwise expressly provided herein,

no failure on the part of any party to exercise, and no delay in exercising, any right, power or remedy hereunder, or otherwise available in respect hereof at law or in equity, shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof or the exercise of any other right, power or remedy.

The Company has not entered, and shall not enter, into any agreement with respect to any of its securities that is inconsistent with the rights granted to the Investors or holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof.

Each party hereto irrevocably agrees that any proceeding with respect to this Agreement or for recognition and enforcement of any judgment in respect thereof brought by the other party hereto or its successors or assigns, may be brought and determined in the Supreme Court of the State of New York in New York County or in the United States District Court for the Southern District of New York, and each party hereto hereby irrevocably submits with regard to any such Proceeding for itself and in respect to its properties, generally and unconditionally, to the exclusive jurisdiction of the aforesaid courts, provided, however, that such consent to jurisdiction is solely for the purpose referred to in this Section 6.10 and shall not be deemed to be a general submission to the jurisdiction of said courts or in the State of New York other than for such purpose.

6.11 Waiver of Jury Trial. To the extent not prohibited by applicable law that cannot be waived, each party hereto waives, and covenants that such party will not assert (whether as plaintiff, defendant or otherwise), any right to trial by jury in any forum in respect of any issue, claim or proceeding arising out of this agreement or the subject matter hereof or in any way connected with the dealings of any party hereto in connection with any of the above, in each case whether now existing or hereafter arising and whether in contract, tort or otherwise. Any party hereto may file an original counterpart or a copy of this Section 6.11 with any court as written evidence of the consent of the parties hereto the waiver of their rights to trial by jury.

6.12 Specific Performance.

Any such party shall, therefore, be entitled (in addition to any other remedy to which such party may be entitled at law or in equity) to injunctive relief, including specific performance, to enforce such obligations, without the posting of any bond, 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.

If no Default or Event of Default has occurred and is continuing or would occur as a result thereof, the prohibitions set forth above are subject to the following exceptions: (a) Restricted Investments acquired by the Company in connection with any Asset Sale consummated in accordance with Section 4, hereof, to the extent such Investments are permitted under such covenant, provided, however, that such Restricted Investments shall be excluded in the calculation of the amount of Restricted Payments previously made for purposes of clause (3) of the preceding paragraph; (b) any purchase or redemption of Equity Interests or Subordinated Indebtedness made by exchange for, or out of the proceeds of the substantially concurrent sale of, Equity Interests of the Company (other than Redeemable Stock and other than Equity Interests issued or sold to a Subsidiary or an employee stock ownership plan), provided, however, that (x) such purchase or redemption shall be excluded in the calculation of the amount of Restricted Payments previously made for purposes of clause (3) of the preceding paragraph and (y) the Net Cash Proceeds from such sale shall be excluded for purposes of clause 3(ii) of the preceding paragraph to the extent utilized for purposes of such purchase or redemption; (c) any purchase or redemption of Subordinated Indebtedness of the Company made by exchange for, or out of the proceeds of the substantially concurrent sale of, Subordinated Indebtedness of the Company or any Restricted Subsidiary that is permitted to be issued pursuant to the provisions of Section 3 hereof, provided, however, that such purchase or redemption shall be excluded in the calculation of the amount of Restricted Payments previously made for purposes of clause (3) of the preceding paragraph; and (d) the purchase of Capital Stock held by employees of the Company or any Subsidiary pursuant to any employee stock ownership plan thereof upon the termination, retirement or death of any such employee in accordance with the provisions of any such plan in an amount not greater than $2,000,000 in any calendar year, provided, however, that any such purchase shall be included in the calculation of the amount of Restricted Payments previously made for purposes of clause (3) of the preceding paragraph.

C-28

Market Value of the Equity Interests or other assets being so distributed at the time of such distribution over the consideration, if any, received therefor.

(3) Limitations on Indebtedness.

The Company shall not, and shall not permit the Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become liable with respect to or become responsible for the payment of, contingently or otherwise (“incur”), any Indebtedness (including any Acquired Indebtedness); provided, however, that the Company or a Guarantor, may incur Indebtedness if at the time of such incurrence and after giving pro forma effect thereto, the Company’s Interest Coverage Ratio for the most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such Indebtedness is incurred, calculated on a pro forma basis as if such Indebtedness was incurred on the first day of such four full fiscal quarter period, would be at least 2.0 to 1.0.

Notwithstanding the foregoing, the limitations of this Section 3 shall not apply to the incurrence of Permitted Indebtedness.

4. Limitations on Asset Sales.

The Company shall not, and shall not permit any Restricted Subsidiary to, make any Asset Sale (other than to the Company or a Guarantor (other than a Foreign Subsidiary of the Company) that is party to the Collateral Documents) unless (i) the Company or such Restricted Subsidiary receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets sold or otherwise disposed of, and (a) in the case of an Asset Sale with respect to assets or property that do not constitute Collateral, at least 75% of the consideration received by the Company or such Restricted Subsidiary from such Asset Sale is in the form of cash or Cash Equivalents or (b) in the case of an Asset Sale with respect to assets or property that constitute Collateral, (1) at least 75% of the consideration received by the Company or such Restricted Subsidiary is in the form of cash, Cash Equivalents or Specified Collateral Assets that become subject to a first priority perfected security interest in favor of the Collateral Agent, on behalf of the Holders, in the manner provided in the Collateral Documents, or any combination thereof and (2) no more than 25% of the consideration received is in the form of Qualified Consideration that becomes subject, upon receipt by the Company or such Restricted Subsidiary and assignment and delivery to the Collateral Agent, to a first priority perfected security interest in favor of the Collateral Agent, on behalf of the Holders, in the manner provided in the Collateral Documents, and (ii) the Net Proceeds received by the Company or such Restricted Subsidiary from such Asset Sale are applied in accordance with the following paragraphs; provided, that for purposes of this Section 4 and any other covenant that requires compliance with this Section 4, the Company shall cause any Designated Unrestricted Subsidiary that consummates an Asset Sale to comply with this Section 4 and the Indenture as though such Designated Unrestricted Subsidiary was a Restricted Subsidiary for purposes of this clause (a) of this Section 4.

(b) In the event of an Asset Sale permitted by clause (a) with respect to assets or property that do not constitute Collateral, if all or a portion of the Net Proceeds of such Asset Sale are not required to be applied to repay permanently any Senior Indebtedness of the Company then outstanding as required by the terms thereof, or the Company determines not to apply such Net Proceeds to the permanent prepayment of any Senior Indebtedness outstanding or

C-29

if no such Senior Indebtedness is then outstanding, then the Company may within 365 days of the Asset Sale, invest the Net Proceeds in the Company or one or more Restricted Subsidiaries. The amount of such Net Proceeds neither used to permanently repay or prepay Senior Indebtedness nor used or invested as set forth in this clause (b) constitutes “Non-Collateral Excess Proceeds.”

(c) When the aggregate amount of Non-Collateral Excess Proceeds from one or more of such Asset Sales equals $10,000,000 or more, the Company shall apply 100% of such Non-Collateral Excess Proceeds within 365 days subsequent to the consummation of such Asset Sale that resulted in the Non-Collateral Excess Proceeds equaling $10,000,000 or more to the purchase of Securities tendered to the Company for purchase at a price equal to 100% of the principal amount thereof, plus accrued interest, if any, and any other amounts due, if any, to the date of purchase pursuant to an offer to purchase made by the Company (a “Non-Collateral Asset Sale Offer”) with respect to the Securities. Any Non-Collateral Asset Sale Offer may include a pro rata offer under similar circumstances to purchase other Senior Indebtedness requiring a similar offer. Any Non-Collateral Asset Sale Offer shall be made substantially in accordance with the procedures described under Section 1109 of the Indenture. Until such time as the Net Proceeds from any Asset Sale with respect to assets or property that do not constitute Collateral are applied in accordance with this Section 4, such Net Proceeds shall be segregated from the other assets of the Company and the Subsidiaries and invested in cash or Cash Equivalents, except that the Company or any Restricted Subsidiary may use any Net Proceeds pending the utilization thereof in the manner (and within the time period) described above, to repay revolving loans (under the Credit Agreements or otherwise) without a permanent reduction of the commitment thereunder.

(d) The Company shall cause a notice of any Non-Collateral Asset Sale Offer to be mailed to the Holders at their registered addresses not less than 30 days nor more than 60 days before the purchase date. Such notice shall contain all instructions and materials necessary to enable Holders to tender their Securities to the Company. Upon receiving notice of a Non-Collateral Asset Sale Offer, Holders may elect to tender their Securities in whole or in part in integral multiples of $1,000 in exchange for cash. To the extent that Holders properly tender Securities in an amount exceeding the Non-Collateral Asset Sale Offer, Securities of tendering Holders will be repurchased on a pro rata basis (based on amounts tendered). To the extent that Holders properly tender Securities in an amount less than the Non-Collateral Asset Sale Offer, any Non-Collateral Excess Proceeds remaining after the completion of the purchase of such tendered Securities may be used by the Company for any purpose not otherwise prohibited by the Indenture or the Collateral Documents. Upon completion of the purchase of all the Securities tendered pursuant to a Non-Collateral Asset Sale Offer (if any), the amount of Non-Collateral Excess Proceeds, if any, shall be reset at zero.

(e) In the event of an Asset Sale permitted by clause (a) of this Section 4 with respect to assets or property that constitute Collateral, upon consummation of any such Asset Sale the Company will apply, or cause the applicable Restricted Subsidiary to apply, the Net Proceeds relating to such Asset Sale within 365 days of such Asset Sale to make an investment in Specified Collateral Assets of the Company or one or more Guarantors; provided, that the Company or a Guarantor, as the case may be, shall own such Specified Collateral Assets, and shall, subject only to Permitted Liens, cause such assets to be subject to a first priority perfected

C-30

Lien under the Collateral Documents. The amount of such Net Proceeds not used or invested as set forth in this clause (e) constitutes “Collateral Excess Proceeds.”

(f) When the aggregate amount of Collateral Excess Proceeds from one or more of such Asset Sales with respect to assets or property that constitute Collateral equals $3,000,000 or more, the Company shall apply 100% of such Collateral Excess Proceeds within 365 days subsequent to the consummation of such Asset Sale that resulted in the Collateral Excess Proceeds equaling $3,000,000 or more to the purchase of Securities tendered to the Company for purchase at a price equal to 100% of the principal amount thereof, plus accrued interest, if any, and any other amounts due, if any, to the date of purchase pursuant to an offer to purchase made by the Company (a “Collateral Asset Sale Offer”) with respect to the Securities. Any Collateral Asset Sale Offer shall be made substantially in accordance with the procedures described under Section 1109 of the Indenture.

(g) Until such time as the Net Proceeds from any such Asset Sale from assets or property that constitute Collateral are applied in accordance with this Section 4, whether before or after the 365 day period referred to in the preceding paragraphs, such Net Proceeds (together with any investment in cash or Cash Equivalents therefrom) shall be segregated from the other assets of the Company or any of its Subsidiaries and shall be held in the Collateral Account.

(h) The Company shall cause a notice of any Collateral Asset Sale Offer to be mailed to the Holders at their registered addresses not less than 30 days nor more than 60 days before the purchase date. Such notice shall contain all instructions and materials necessary to enable Holders to tender their Securities to the Company. Upon receiving notice of a Collateral Asset Sale Offer, Holders may elect to tender their Securities in whole or in part in integral multiples of $1,000 in exchange for cash. To the extent that Holders properly tender Securities in an amount exceeding the Collateral Asset Sale Offer, Securities of tendering Holders shall be repurchased on a pro rata basis (based on amounts tendered). To the extent that Holders properly tender Securities in an amount less than the Collateral Asset Sale Offer, any Collateral Excess Proceeds remaining after the completion of the purchase of such tendered Securities may be used by the Company for any purpose not otherwise prohibited by the Indenture or the Collateral Documents. Upon completion of the purchase of all the Securities tendered pursuant to a Collateral Asset Sale Offer (if any), the amount of Collateral Excess Proceeds, if any, shall be reset at zero.

(i) In the event the Company is required to make an Asset Sale Offer at a time when the Company is prohibited from making such an Asset Sale Offer, the Company shall, on or prior to the date that the Company is required to make an Asset Sale Offer, (i) seek the consent of its lenders to repurchase Securities pursuant to such an Asset Sale Offer or (ii) refinance the Indebtedness that prohibits such Asset Sale Offer; provided, however, that the failure to make or consummate such Asset Sale Offer as provided herein shall constitute an Event of Default.

(j) The Company shall comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act, any other tender offer rules under the

C-31

Exchange Act and other securities laws or regulations in connection with any offer to repurchase and the repurchase of the Securities as described above.

(k) The Company shall not, and shall not permit any of the Restricted Subsidiaries to, create or permit to exist or become effective any consensual restriction (other than restrictions not more restrictive taken as a whole (as determined in good faith by the chief financial officer of the Company) than those in effect under (i) Existing Indebtedness and (ii) Indebtedness under the Credit Agreements) that would materially impair the ability of the Company to comply with the provisions of this Section 4.

(l) Notwithstanding anything herein to the contrary, neither the Company nor any Restricted Subsidiary shall be permitted to make an investment in any Specified Collateral Assets in accordance with the foregoing paragraphs of this Section 4, unless the conditions set forth in Section 5.12(e) of the Security Agreement shall have been satisfied.
