TO EACH PURCHASER LISTED ON THE ATTACHED SCHEDULE A WHO IS A SIGNATORY HERETO (COLLECTIVELY WITH THEIR RESPECTIVE SUCCESSORS AND ASSIGNS, THE “PURCHASERS”):

Ladies and Gentlemen:

THIS SENIOR SECURED NOTE AND WARRANT PURCHASE AGREEMENT (this “Agreement”) is hereby entered into by and among the Purchasers, ORTHOVITA, INC., a Pennsylvania corporation (the “Company”), and LB I Group Inc., a Delaware corporation, as Collateral Agent, with reference to the following (and with the definitions of terms set forth in Schedule B being applicable hereto):

The Company has requested that the Purchasers provide the Company with a $45,000,000 senior secured note purchase facility, the proceeds of which are to be used by the Company to effect the RST I Royalty Repurchase, to repay all amounts owed under the GECC Financing and other Indebtedness of the Credit Parties, to expand the Company’s sales force, to develop and, from time to time, to acquire new products, and for other general business purposes of the Company, including capital expenditures.

The Purchasers are willing to do so, subject to the terms and conditions hereof.

NOW THEREFORE, the Purchasers, the Company, and the Collateral Agent hereby agree as follows:

SECTION 1. AUTHORIZATION, SALE AND ISSUANCE OF NOTES AND WARRANTS.

Section 1.1 Authorization.

(a) The Company has authorized the issue and sale of $45,000,000 aggregate principal amount of its 10% Senior Secured Notes (the “Notes”, such term to include any such notes issued in substitution therefor pursuant to Section 11 of this Agreement) due July 30, 2012. The Notes shall be substantially in the form set forth on Exhibit A.

(b) The Company has further authorized the issuance and sale to each Purchaser of Warrants (the “Warrants”, such term to include any such warrants issued in substitution therefor pursuant to the terms thereof) to purchase Common Stock, par value $0.01 per share, of the Company (“Common Stock”), each substantially in the form set forth in Exhibit B.

Section 1.2 Sale and Purchase of the Notes and Warrants; Additional Advances. Subject to the terms and conditions of this Agreement:

(a) The Company hereby agrees to issue and sell to each Purchaser, and each Purchaser agrees, severally, to purchase from the Company (such transaction, the “Initial Issuance”), a Note, containing the same terms and conditions as set forth in the form of

note attached hereto as Exhibit A, in the aggregate principal amount equal to the Commitment of such Purchaser at a purchase price of 25/45^thsof the aggregate principal amount of such Note (the “Purchase Price”). The aggregate amount of the Commitments on the Agreement Date is $45,000,000.

(b) As further consideration for the purchase of the Notes by the Purchasers pursuant to Section 1.2(a), the Company agrees to issue and deliver to each Purchaser a Warrant to purchase up to that number of shares of Common Stock set forth opposite such Purchaser’s name on Schedule A.

(c) On each Additional Advance Date occurring during the period from and including the Closing to but excluding January 27, 2010, each Purchaser agrees, at the request of the Company, to make additional advances under the Note held by such Purchaser (each such advance, an “Additional Advance”), in an aggregate principal amount that, together with all other Loans of such Purchaser, will not exceed the Commitment of such Purchaser at such time.

(d) Each Purchaser’s obligation hereunder is several and not joint with the other Purchasers’ obligations such that no Purchaser shall have any obligation or liability to any Person for the performance or nonperformance by any other Purchaser hereunder.

(e) The Company and each Purchaser hereby acknowledge and agree that the Notes and Warrants issued in accordance with this Agreement constitute an “investment unit” for the purposes of Section 1273(c)(2)(A) of the Code. In accordance with Sections 1273(c)(2)(A) and 1273(b)(2) of the Code, the issue price of the investment unit is 100% of the aggregate principal amount of the Notes set forth opposite each such Purchaser’s name on Schedule A. Allocating that issue price between the Note and Warrant based on their relative fair market values, as required by Section 1273(c)(2)(B) of the Code and Treasury Regulation Section 1.1273-2(h)(1), results in (i) the Notes having an issue price of 90.9% of the aggregate principal amount of such Note and (ii) the Warrant having a Purchase Price of 9.1% of the aggregate principal amount of such Notes. Additional Advances evidenced by such Notes and Warrants exercisable in connection therewith shall be allocated in the same manner. The Company and each Purchaser agrees to prepare their respective federal income tax returns in a manner consistent with the foregoing agreement.

Section 1.3 Closing of the Initial Issuance. The Initial Issuance and the issuance of the Warrants shall occur at a closing (the “Closing”) at the offices of Pillsbury ▇▇▇▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇ LLP, at 10:00 a.m. local time on July 30, 2007, or on such other Business Day thereafter as may be agreed upon by the Company and all of the Purchasers. At the Closing:

(a) The Company will deliver to, or at the direction of, each Purchaser the Note to be purchased thereby, which shall be dated the date of the Closing and registered in such Purchaser’s name, against delivery by such Purchaser to the Company of the amount of the Purchase Price therefor.

(b) The Company will deliver to, or at the direction of, each Purchaser a Warrant, which shall be dated the date of the Closing and registered in the name of such Purchaser, evidencing the right of such Purchaser to purchase up to that number of shares of Common Stock set forth opposite such Purchaser’s name on Schedule A.

Section 1.4 Additional Advances. The Company shall give each Purchaser notice (which shall be irrevocable) no later than ten (10) Business Days before the requested date of each Additional Advance (each such date, an “Additional Advance Date”). Each such notice shall be in the form of Exhibit 1.4 and shall specify: (i) the requested Additional Advance Date, which shall be a Business Day; (ii) the aggregate amount of the Additional Advances to be made on such Additional Advance Date, which amount shall be not less than the lesser of $5,000,000 and the aggregate amount of the unused Commitments; and (iii) the Purchaser’s ratable share of such aggregate amount, based upon the relationship that such Purchaser’s Commitment bears to the total amount of the Commitments, in each case on such Additional Advance Date. Not later than 12:00 a.m. (New York time) on each Additional Advance Date, each Purchaser shall disburse to the Company, in immediately available funds, such Purchaser’s ratable share of the total amount of the Additional Advances to be made on such date in accordance with such notice.

Section 1.5 Evidence of Loans. Each Purchaser’s Loans and the Company’s obligation to repay such Loans, with interest in accordance with the terms of this Agreement, shall be evidenced by this Agreement, the records of, and the Notes held by, such Purchaser. The records of each Purchaser and any notations by such Purchaser on any Note regarding payments made on account of the principal thereof, in absence of manifest error, shall be conclusive and binding; provided that in no event shall (i) the failure by a Purchaser to make any such notation, or (ii) any manifest error therein obligate the Company to pay any amounts in excess of amounts otherwise payable hereunder or under such Note.

Section 1.6 Payment Terms of the Notes. The Notes shall bear interest, in the amounts and payable at the times set forth therein, and shall be due and payable in full on the Maturity Date or as otherwise provided for under this Agreement without defense, set off or counterclaim of any sort. All payments required to be made under the Notes shall be made in the manner and to the account of each Purchaser as set forth in the Notes.

Section 1.7 Reduction of Commitments. The Company shall give prompt notice to the Purchasers if, at any time during the period from and including the Closing to but excluding January 27, 2010, the Company determines that it does not intend to request any Additional Advances, whereupon the Commitments shall be reduced to the outstanding principal amount of the Loans. The Commitments shall automatically be reduced to the outstanding principal amount of the Loans on the date of, and after giving effect to, any prepayment of the Loans pursuant to Section 6.2.

Section 1.8 Pro Rata Treatment. Except to the extent otherwise provided herein, (a) Loans shall be made by the Purchasers pro rata in accordance with their respective Commitments, (b) each reduction in the Commitments shall be made pro rata in accordance with the respective amounts thereof, and (c) each payment of the principal of, or interest on, the Notes shall be made for the account of the Purchasers pro rata in accordance with their respective amounts thereof then due and payable.

Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in Section 3 of ERISA), and no event, transaction or condition has occurred or exists that could reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition of any Lien on any of the rights, properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Code, other than such liabilities or Liens as could not reasonably be expected to be, individually or in the aggregate, Material.

No Credit Party is in default and no waiver of default is currently in effect, in the payment of any principal or interest on any Indebtedness of such Credit Party and no event or condition exists with respect to any Indebtedness of such Credit Party that would permit (or that with notice or the lapse of

time, or both, would permit) one or more Persons to cause such Indebtedness to become due and payable before its stated maturity or before its regularly scheduled dates of payment.

(b) Except as disclosed in Schedule 3.15(b), no Credit Party has agreed or consented to cause or permit in the future (upon the happening of a contingency or otherwise) any of its property, whether now owned or hereafter acquired, to be subject to a Lien other than Permitted Liens.

Section 3.16 Foreign Assets Control Regulations, Etc. Neither the sale of the Notes by the Company hereunder nor its use of the proceeds thereof will violate the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating thereto. Without limiting the foregoing, neither the Company nor any of its Subsidiaries (a) is or will become a blocked person described in Section 1 of Executive Order 13224 of September 23, 2001 Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten to Commit, or Support Terrorism (66 Fed.

Section 3.17 Status under Certain Statutes. No Credit Party is an “investment company” registered or required to be registered subject to regulation under the Investment Company Act of 1940, as amended, or is subject to regulation under the Public Utility Holding Company Act of 1935, as amended, or the Federal Power Act, as amended.

(b) the Company has no knowledge of any facts which would give rise to any claim, public or private, of violation of Environmental Laws or damage to the environment emanating from, occurring on or in any way related to real properties now or formerly owned, leased or operated by any Credit Party or to other assets of the Credit Parties or their use, except, in each case, such as would not reasonably be expected to result in a Materially Adverse Effect;

(c) no Credit Party has stored any Hazardous Materials on real properties now or formerly owned, leased or operated by any of them or has disposed of any Hazardous Materials in a manner contrary to any Environmental Laws in each case in any manner that could reasonably be expected to result in a Materially Adverse Effect; and

(d) all buildings on all real properties now owned, leased or operated by any Credit Party are in compliance with applicable Environmental Laws, except where failure to comply could not reasonably be expected to result in a Materially Adverse Effect.

Section 3.19 Solvency. As of the date of this Agreement, at the Closing, both before and after giving effect to the Closing Date Transactions, and at the time of each Additional Advance, each Credit Party: (a) owns assets the fair saleable value of which are (i) greater than the total amount of its liabilities (including contingent liabilities) and (ii) greater than the amount that will be required to pay its probable liabilities as they mature; (b) has capital that is not unreasonably small in relation to its businesses as presently conducted or any undertaken transaction; and (c) does not intend to incur and does not believe that it will incur debts beyond its ability to pay such debts as they become due. For purposes of this Section 3.19, in computing the amount of contingent liabilities of any Credit Party at any time, it is intended that such liabilities will be computed at the amount which, in light of all facts and circumstances existing at such time, represents the amount that reasonably can be expected to become an actual matured liability of such Credit Party.

Section 3.20 Status of Security Interest. The Collateral Documents create in favor of the Collateral Agent a legal, valid and enforceable security interest in the Collateral.

SECTION 4. REPRESENTATIONS OF THE PURCHASERS.

Section 4.1 Representations to the Company. Each Purchaser represents and warrants to the Company, severally and not jointly, with respect to its purchase of its Note and Warrant as follows:

(a) Such Purchaser is purchasing the Note and Warrant for investment for Purchaser’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act. Such Purchaser is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act, and, in any case, has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of purchasing such Note and Warrant. Such Purchaser has not been formed for the purpose of investing such Note and Warrant.

(b) Such Purchaser understands that the Note and Warrant that such Purchaser is purchasing have not been registered under the Securities Act by reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of such Purchaser’s investment intent as expressed herein.

(c) Such Purchaser further acknowledges and understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available and the Securities may be imprinted with a legend indicating such restrictions on the transferability thereof.

(d) Such Purchaser understands that the Securities are presently characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations, such securities may be resold without registration under the Securities Act only in certain limited circumstances. In this connection, such Purchaser represents that it is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

(e) Such Purchaser represents that at least one of the following statements is an accurate representation as to each source of funds (a “Source”) to be used by such Purchaser to pay the Purchase Price of the Notes to be purchased by such Purchaser hereunder:

(i) if such Purchaser is an insurance company, the Source does not include assets allocated to any separate account maintained by such company in which any employee benefit plan (or its related trust) has any interest, other than a separate account that is maintained solely in connection with such company’s fixed contractual obligations under which the amounts payable, or credited, to such plan and to any participant or beneficiary of such plan (including any annuitant) are not affected in any manner by the investment performance of the separate account; or

(ii) the Source is either (i) an insurance company pooled separate account, within the meaning of Prohibited Transaction Exemption (“PTE”) 90-1 (issued January 29, 1990), or (ii) a bank collective investment fund, within the meaning of the PTE 91-38 (issued July 12, 1991) and, except as such Purchaser has disclosed to the Company in writing pursuant to this paragraph (b), no employee benefit plan or group of plans maintained by the same employer or employee organization beneficially owns more than 10% of all assets allocated to such pooled separate account or collective investment fund; or

(iii) the Source constitutes assets of an “investment fund” (within the meaning of Part V of the QPAM Exemption) managed by a “qualified professional asset manager” or “QPAM” (within the meaning of Part V of the QPAM Exemption), no employee benefit plan’s assets that are included in such investment fund, when combined with the assets of all other employee benefit plans established or maintained by the same employer or by an affiliate (within the meaning of Section V(c)(1) of the QPAM Exemption) of such employer or by the same employee organization and managed by such QPAM, exceed 20% of the total client assets managed by such QPAM, the conditions of Part I(c) and (g) of the QPAM Exemption are satisfied, neither the QPAM nor a person controlling or

controlled by the QPAM (applying the definition of “control” in Section V(e) of the QPAM Exemption) owns a 10% or more interest in the Company and (x) the identity of such QPAM and (y) the names of all employee benefit plans whose assets are included in such investment fund have been disclosed to the Company in writing pursuant to this paragraph (iii); or

(iv) the Source is a governmental plan; or

(v) the Source is one or more employee benefit plans, or a separate account or trust fund comprised of one or more employee benefit plans, each of which has been identified to the Company in writing pursuant to this paragraph (v); or

(vi) the Source does not include assets of any employee benefit plan, other than a plan exempt from the coverage of ERISA.

As used in this Section 4.1, the terms “employee benefit plan,” “governmental plan,” “party in interest” and “separate account” shall have the respective meanings assigned to such terms in Section 3 of ERISA.

Section 4.2 Exculpation of the Purchasers. Each Purchaser acknowledges that it is not relying upon any Person (including the Collateral Agent or any other Purchaser), other than the Credit Parties and their respective officers (acting in their respective capacities as representatives of the Credit Parties), in deciding to invest and in making its investment in the purchase of the Notes and Warrants. Each Purchaser agrees that none of the Collateral Agent, any other Purchaser, or any of their respective controlling Persons, officers, directors, partners, agents or employees shall be liable to such Purchaser for any losses incurred by such Purchaser in connection with its purchase of the Notes and Warrants.

SECTION 6. PREPAYMENT OF THE NOTES.

Section 6.1 Required Prepayments. In addition to paying the remaining outstanding principal amount and the interest due on the Notes on the Maturity Date or upon acceleration of the Notes pursuant to Section 10, if a Mandatory Prepayment Event occurs, the Company agrees as follows: Promptly upon the consummation of such Mandatory Prepayment Event, the Company shall give the Purchasers written notice of such Mandatory Prepayment Event with a description in reasonable detail of such Mandatory Prepayment Event including, the calculation of the Net Proceeds received in connection therewith and, for each Purchaser, the amount of such Purchaser’s Pro Rata Portion of such Net Proceeds and the Make-Whole Amount. The Net Proceeds and the Make-Whole Amount received by the Company or any of its Subsidiaries in connection with such Mandatory Prepayment Event shall be forthwith applied to the outstanding principal balance of the Notes.

Section 6.2 Optional Prepayments with Make-Whole Amount. The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of the Notes, in a minimum amount not less than $2,000,000 and in increments of at least $1,000,000 in excess of such minimum, in the case of a partial prepayment, at 100% of the principal amount so prepaid, together with interest accrued thereon to the date of such prepayment, plus the Make-Whole Amount, if any, determined for the prepayment date with respect to such principal amount. The Company will give each Purchaser written notice of each optional prepayment under this Section 6.2 not less than five (5) days prior to the date fixed for such prepayment. Each such notice shall specify such date, the aggregate principal amount of the Notes to be prepaid on such date, the principal amount of each Note held by such Purchaser to be prepaid, and the interest and Make-Whole Amount, if any, to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of the Senior Financial Officer specifying the computation of the Make-Whole Amount due in connection with such prepayment and setting forth the details of such computation.

From and after such prepayment date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

SECTION 7. AFFIRMATIVE COVENANTS.

The Company covenants, jointly and severally, that so long as any of the Notes are outstanding and the Commitments have not been terminated:

Section 7.1 Compliance with Law. The Company will, and will cause each of its Subsidiaries to, comply with all Applicable Laws to which each of them is subject, including, without limitation, Environmental Laws, and to obtain and maintain in effect all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations could not, individually or in the aggregate, reasonably be expected to have a Materially Adverse Effect.

Section 7.2 Insurance. The Company will, and will cause each of its Subsidiaries to, maintain, with financially sound insurers, insurance with respect to their respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and self insurance, if adequate reserves are maintained with respect thereto) as is customary in the case of similarly situated entities of established reputations engaged in the same or a similar business and similarly situated. The Collateral Agent shall be named as “Purchaser’s loss payee” on all insurance policies relating to any Collateral and as “additional insured” under all liability policies (except Directors’ and Officers’ Insurance, automobile insurance, workers’ compensation, fiduciary liability and employment practices), in each case pursuant to appropriate endorsements in form and substance reasonably satisfactory to the Collateral Agent.

Section 7.3 Maintenance of Properties. The Company will, and will cause each of its Subsidiaries to, maintain and keep, or cause to be maintained and kept, their respective properties in good repair, working order and condition (other than ordinary wear and tear), so that the business carried on in connection therewith may be properly conducted at all times, except where the failure to maintain or keep, or the discontinuance of the operation of, such properties could not reasonably be expected to have a Materially Adverse Effect.

Section 7.4 Payment of Taxes and Claims. The Company will, and will cause each of its Subsidiaries to, file all tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes,

assessments, governmental charges, or levies imposed on them or any of their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent and all claims for which sums have become due and payable that have or might become a Lien (other than Liens permitted by Section 8.3) on properties or assets of the Company or any Subsidiary; provided that neither the Company nor any Subsidiary need pay any such tax or assessment or charge or claim if the amount, applicability or validity thereof is contested by the Company or such Subsidiary on a timely basis in good faith and in appropriate proceedings, and the Company or a Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Company or such Subsidiary.

Section 7.5 Corporate Existence, Etc. Subject to Section 8.2, the Company will, and will cause each of its Subsidiaries to, and the Company will, and will cause each Subsidiary to, at all times preserve and keep in full force and effect its corporate existence and the corporate existence of each of such Subsidiary and all rights and franchises of the Company and such Subsidiaries, and engage only in businesses in substantially the same fields as the businesses conducted on the Agreement Date.

Section 7.6 Minimum Cash Balance. The Company will at all times maintain a minimum cash balance at least equal to 25% of the then outstanding principal amount on the Notes (such amount, the “Minimum Required Amount”) in a separate interest-bearing deposit or other similar demand investment account that is pledged to the Collateral Agent for the benefit of the Purchasers as collateral security for the prompt and full payment of the Notes and which such account is subject to a control account agreement, in form and substance reasonably satisfactory to the Collateral Agent, between the applicable financial intermediary where such account is held and the Collateral Agent (such account, the “Cash Maintenance Account”). Until exercise by the Collateral Agent of its control rights as hereinafter provided, the Company shall have the right to withdraw amounts from the Cash Maintenance Account without the consent of the Collateral Agent. If at any time the cash balance in the Cash Maintenance Account falls below an amount equal to 40% of the outstanding principal amount on the Notes at such time, then, within five Business Days thereafter, the Company shall provide to, and maintain in favor of, the Collateral Agent for the benefit of the Purchasers, one or more direct pay letters of credit (such letters of credit, “Collateral L/Cs”) having at all times an aggregate stated amount at least equal to the Minimum Required Amount. The Collateral L/Cs shall be in form and substance, and issued by commercial banks located in the United States, satisfactory to the Collateral Agent. Without limiting the foregoing, each Collateral L/C shall (i) have a tenor of at least 364 days and (ii) shall provide that it may not be terminated without the consent of the Collateral Agent and that it may been drawn by the Collateral Agent upon certification that such drawing is permitted under this Section 7.6 or if such Collateral L/C has not been extended within thirty days of its expiry date. In the event that the Purchaser fails to provide or maintain Collateral L/Cs as required hereunder, or during the occurrence of a Default, the Collateral Agent may exercise its control rights over the Cash Maintenance Account and/or draw under any Collateral L/Cs and apply the proceeds thereof in accordance with the applicable provisions of the Collateral Documents. Delivery and maintenance of Collateral L/Cs complying with the terms of this Section 7.6 shall be in lieu of, and deemed to satisfy the requirements of the first sentence hereof. If, after delivery and maintenance by the Company of Collateral L/Cs at all times in compliance with this Section 7.6, (y) the cash balance in the Cash Maintenance Account is restored to an amount greater than or equal to the Minimum Required Amount and

such amount is maintained for a period of 30 consecutive days, and (z) no Default shall have occurred or been continuing during such 30 day period, then the Collateral Agent shall consent to the termination of the Collateral L/Cs, and the rights and obligations of the Company and the Collateral Agent under this Section 7.6 shall be restored as if cash in the Minimum Required Amount were at all times maintained in the Cash Maintenance Account.

Section 7.7 Subsidiary Documentation. Except for the transaction described in and permitted under Section 8.5(c), in connection with and within five Business Days of the creation, acquisition and/or capitalization by the Company or any Subsidiary of the Company of a new Subsidiary (a “New Subsidiary”) on or after the Agreement Date, the Company will, and will cause each of its Subsidiaries to, and the Company will, and will cause each Subsidiary to, satisfy the following requirements:

(a) If an Event of Default with respect to the Company described in paragraph (g) or (h) of Section 9 (other than an Event of Default described in clause (i) of paragraph (g) or described in clause (vi) of paragraph (g) by virtue of the fact that such clause encompasses clause (i) of paragraph (g)) has occurred, all the Notes then outstanding shall automatically become immediately due and payable.

(b) If any Event of Default other than those set forth in Section 10.1(a) has occurred and is continuing, the Super-Majority Purchasers may at any time at its or their option, by notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable.

otherwise.

SECTION 18. CONFIDENTIAL INFORMATION.

For the purposes of this Section 18, “Confidential Information” means information delivered to a Purchaser by or on behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise obtained pursuant to this Agreement, including without limitation, any information obtained pursuant to any inspection performed by the Collateral Agent or any Purchaser pursuant to Section 5.3, that is proprietary in nature; provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser without restriction prior to the time of such disclosure as evidenced by its written records, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any Person acting on its behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or any Subsidiary in a manner that does not, and is not alleged by the Company to, violate any Applicable Law or any other agreement applicable to such information, or (d) constitutes financial statements delivered to a Purchaser under Section 5.1 that are otherwise publicly available, except in the case of clause (a), (b), or (c), to the extent such information came from a source known to such Purchaser to be bound by an obligation of confidentiality to the Company as any of its Subsidiaries.

SECTION 19. THE COLLATERAL AGENT.

Section 19.1 Appointment; Nature of Relationship. LB I Group Inc. is appointed by the Purchasers as the Collateral Agent hereunder and under each of the other Related Documents, and each of the Purchasers irrevocably authorizes the Collateral Agent (for so long as the Collateral Agent remains in such capacity under this Agreement) to act as the contractual representative of such Purchaser with only the rights and duties expressly set forth herein and in the other Related Documents. The Collateral Agent agrees to act as such contractual representative upon the express conditions contained in this Section 19. Notwithstanding the use of the defined term “Collateral Agent” it is expressly understood and agreed that the Collateral Agent shall not have any fiduciary responsibilities to any Purchaser by reason of this Agreement and that the Collateral Agent is merely acting as the representative of the Purchasers with only those duties as are expressly set forth in this Agreement and the other Related Documents. In its capacity as the Purchasers’ contractual representative, the Collateral Agent (i) does not assume any fiduciary duties to any of the Purchasers, (ii) is a “representative” of the Purchasers within the meaning of Section 9-511 of the UCC and (iii) is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the other Related Documents. Each of the Purchasers agrees to assert no claim against the Collateral Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Purchaser waives.

Section 19.2 Powers. The Collateral Agent shall have and may exercise such powers under the Related Documents as are specifically delegated to the Collateral Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Collateral Agent shall have no implied duties or fiduciary duties to the Purchasers, or any

obligation to the Purchasers to take any action hereunder or under any of the other Related Documents except any action specifically provided by the Related Documents required to be taken by the Collateral Agent.

Section 19.3 General Immunity. Neither the Collateral Agent nor any of its directors, officers, agents or employees shall be liable to the Company, any Subsidiary or Affiliate of the Company, or any Purchaser for any action taken or omitted to be taken by it or them hereunder or under any other Related Documents or in connection herewith or therewith except to the extent such action or inaction is found in a final judgment by a court of competent jurisdiction to have arisen solely from (i) the gross negligence or willful misconduct of such Person or (ii) breach of contract by such Person with respect to the Related Documents.

Section 19.4 No Responsibility for Loans, Creditworthiness, Collateral, Recitals, Etc. Neither the Collateral Agent nor any of its directors, officers, Collateral Agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify (i) any statement, warranty or representation made in connection with any Related Document or any borrowing hereunder; (ii) the performance or observance of any of the covenants or agreements of any obligor under any Related Document; (iii) the satisfaction of any condition specified in Section 2, except receipt of items required to be delivered solely to the Collateral Agent; (iv) the existence or possible existence of any Default; or (v) the validity, effectiveness or genuineness of any Related Document or any other instrument or writing furnished in connection therewith. The Collateral Agent shall not be responsible to any Purchaser for any recitals, statements, representations or warranties herein or in any of the other Related Documents, for the perfection or priority of any of the Liens on any of the Collateral, or for the execution, effectiveness, genuineness, validity, legality, enforceability, collectibility, or sufficiency of this Agreement or any of the other Related Documents or the transactions contemplated thereby, or for the financial condition of any guarantor of any or all of the Obligations, the Company or any of its Subsidiaries.

Section 19.5 Action on Instructions of Purchasers. The Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Related Document in accordance with written instructions signed by the Super-Majority Purchasers (or any other percentage of Purchasers specified to be the applicable percentage in this Agreement or any other Related Document to act on specified matters), and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Purchasers and on all holders of Notes. The Collateral Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Related Document unless it shall first be indemnified to its satisfaction by the Purchasers pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action.

Section 19.6 Employment of Collateral Agents and Counsel. The Collateral Agent may execute any of its duties as the Collateral Agent hereunder and under any other Related Document by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Purchasers, except as to money or securities received by it or its authorized agents. The Collateral Agent shall be entitled to advice of counsel concerning the contractual arrangement between the Collateral Agent and the Purchasers and all matters pertaining to the Collateral Agent’s duties hereunder and under any other Related Document.

Section 19.7 Reliance on Documents; Counsel. The Collateral Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and, in respect to legal matters, upon the opinion of counsel selected by the Collateral Agent, which counsel may be employees of the Collateral Agent.

Section 19.8 The Collateral Agent’s Reimbursement and Indemnification. The Purchasers agree to reimburse and indemnify the Collateral Agent ratably in proportion to the principal amount of their respective Notes outstanding from time to time (i) for any amounts not reimbursed by the Company for which the Collateral Agent is entitled to reimbursement under the Related Documents, (ii) for any other expenses incurred by the Collateral Agent on behalf of the Purchasers, in connection with the preparation, execution, delivery, administration and enforcement of the Related Documents and (iii) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Collateral Agent in any way relating to or arising out of the Related Documents or any other document delivered in connection therewith or the transactions contemplated thereby, or the enforcement of any of the terms thereof or of any such other documents, provided that no Purchaser shall be liable for any of the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by a court of competent jurisdiction to have arisen solely from the gross negligence or willful misconduct of the Collateral Agent.

Section 19.9 Rights as a Purchaser. With respect to its Notes, the Collateral Agent shall have the same rights and powers hereunder and under any other Related Document as any Purchaser and may exercise the same as though it were not the Collateral Agent, and the term “Purchaser” or “Purchasers” shall, unless the context otherwise indicates, include the Collateral Agent in its individual capacity.

Section 19.10 Successor Collateral Agent. The Collateral Agent may resign at any time by written notice to the Purchasers and the Credit Parties, and the Collateral Agent may be removed at any time with or without cause by written notice received by the Collateral Agent from the Super-Majority Purchasers. Upon any such resignation or removal, the Super-Majority Purchasers shall have the right to appoint, on behalf of the Credit Parties and the Purchasers, a successor Collateral Agent. If no successor Collateral Agent shall have been so appointed by the Super-Majority Purchasers and shall have accepted such appointment within thirty days after the retiring Collateral Agent’s giving notice of resignation, then the retiring Collateral Agent may appoint, on behalf of the Credit Parties and the Purchasers, a successor Collateral Agent. Notwithstanding anything herein to the contrary, so long as no Default has occurred and is continuing, each such successor Collateral Agent shall be subject to approval by the Credit Parties, which approval shall not be unreasonably withheld. Upon the acceptance of any appointment as the Collateral Agent hereunder by a successor Collateral Agent, such successor Collateral Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent, and the retiring Collateral Agent shall be discharged from its duties and obligations hereunder and under the other Related Documents. After any retiring Collateral Agent’s resignation hereunder as Collateral Agent, the provisions of this Section 19 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Collateral Agent hereunder and under the other Related Documents.

Section 19.11 Collateral Documents.

(a) Each Purchaser authorizes the Collateral Agent to enter into the Collateral Documents to which it is a party and to take all action contemplated by such documents. Each Purchaser agrees that no holder of the Notes (other than the Collateral Agent) shall have the right individually to seek to realize upon the security granted by any Collateral Document, it being understood and agreed that such rights and remedies may be exercised solely by the Collateral Agent for the benefit of the Purchasers upon the terms of the Collateral Documents.

(b) In the event that any Collateral is hereafter pledged by any Person as collateral security for the Obligations, the Collateral Agent is hereby authorized to execute and deliver on behalf of the Purchasers any Related Documents necessary or appropriate to grant and perfect a Lien on such Collateral in favor of the Collateral Agent on behalf of the Purchasers.

(c) The Purchasers hereby authorize the Collateral Agent, at its option and in its discretion, to (y) release any Lien granted to or held by the Collateral Agent upon any Collateral and/or (z) release any guarantor from its obligations under any Guaranty (i) upon the satisfaction of all of the Obligations at any time arising under or in respect of this Agreement or the Related Documents or the transactions contemplated hereby or thereby; (ii) in connection with any transaction permitted by, but only in accordance with, the terms of the applicable Related Document; or (iii) in connection with any transaction approved, authorized or ratified in writing by the Super-Majority Purchasers, unless such release is required to be approved by all of the Purchasers hereunder. Upon request by the Collateral Agent at any time, the Purchasers will confirm in writing the Collateral Agent’s authority to release particular types or items of Collateral pursuant to this Section 19.11.

(d) Upon any sale or transfer of assets constituting Collateral which is permitted pursuant to the terms of any Related Document, or consented to in writing by the Super-Majority Purchasers, the Collateral Agent shall (and is hereby irrevocably authorized by the Purchasers to) execute such documents as may be necessary to evidence the release of the Liens granted to the Collateral Agent for the benefit of the Purchasers herein or pursuant hereto upon the Collateral that was sold or transferred; provided, however, that (i) the Collateral Agent shall not be required to execute any such document on terms which, in the Collateral Agent’s reasonable opinion, would expose the Collateral Agent to liability or create any obligation or entail any consequence other than the release of such Liens without recourse or warranty, and (ii) such release shall not in any manner discharge, affect or impair the Obligations or any Liens upon (or obligations of the Company or any of its Subsidiaries in respect of) all interests retained by the Company or any of its Subsidiaries, including (without limitation) the proceeds of the sale, all of which shall continue to constitute part of the Collateral.

SECTION 20. MISCELLANEOUS.

Section 20.5 Construction. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.

Section 20.6 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

Nothing herein shall affect the right of the Agent, any Bank or any other Indemnified Person to serve process in any other manner permitted by law or shall limit the right of the Agent, any Bank or any other Indemnified Person to bring proceedings against the Borrower in the courts of any other jurisdiction. Any judicial proceeding by the Borrower against the Agent or any Bank involving any Related Document Related Claim shall be brought only in a court located in, in the case of the Agent, the City and State of New York and, in the case of a Bank, the jurisdiction in which such Bank’s principal United States office is located. THE BORROWER, THE AGENT AND EACH BANK HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING ANY RELATED DOCUMENT RELATED CLAIM.

Section 20.9 Waiver of Jury Trial. The Company irrevocably waives, to the fullest extent permitted by law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or any other Related Document or the transactions contemplated thereby.

Section 20.10 Indemnity.

If the undertaking to indemnify, pay and hold harmless set forth in the preceding sentence may be unenforceable because it violates of any law or public policy, the Company shall contribute the maximum portion which it is permitted to pay and satisfy under Applicable Law, to the payment and satisfaction of all Related Document Related Claims incurred by the Indemnitees. This Section 20.9 shall survive the full payment of the Obligations and the termination of the Commitments or any other Related Document.

Section 20.11 LIMITATION OF LIABILITY. NO PURCHASER OR ANY OTHER INDEMNIFIED PERSON SHALL HAVE ANY LIABILITY WITH RESPECT TO, AND THE COMPANY HEREBY WAIVES, RELEASES AND AGREES NOT TO SUE FOR, ANY SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES SUFFERED BY THE COMPANY IN CONNECTION WITH ANY RELATED DOCUMENT RELATED CLAIM.
