The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of the Company and no other corporate proceedings on the part of the Company are necessary to authorize this Agreement or to consummate the transactions contemplated hereby. Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will (i) result in any violation of any provision of the Certificate of Incorporation or By-laws of the Company, or (ii) result in any violation of any loan or credit agreement, note, mortgage, indenture, lease, or other agreement, obligation, instrument, permit, concession, franchise, license, judgment, order, decree, statute, law, ordinance, rule or regulation applicable to Company or its properties or assets which violation, in the case of clause (ii), individually or in the aggregate, would reasonably be expected to be material to the Company.

(c) The Company hereby appoints the Rights Agent to act as rights agent for the Company in accordance with the express terms and conditions set forth in this Agreement, and the Rights Agent hereby accepts such appointment.

2.2 Nontransferable. The CVRs may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than through a Permitted Transfer. Any purported transfer of a CVR other than in a Permitted Transfer shall be null and void ab initio.

2.3 No Certificate; Registration; Registration of Transfer; Change of Address.

(a) The CVRs will be issued in book-entry form only and will not be evidenced by a certificate or other instrument.

(b) The Rights Agent will keep a register (the “CVR Register”) for the registration of the CVRs. The Rights Agent is hereby initially appointed “CVR Registrar” for the purpose of registering the CVRs and Permitted Transfers of the CVRs as herein provided. Upon any change in the identity of the Rights Agent, the successor Rights Agent will automatically also become the successor CVR Registrar.

(c) Subject to the restrictions on transferability set forth in Section 2.2, every request made to transfer a CVR must be in writing and accompanied by a written instrument or instruments of transfer and any other requested documentation in a form reasonably satisfactory to the Company and the CVR Registrar, duly executed by the registered Holder or Holders thereof or by the duly appointed legal representative thereof or by a duly authorized attorney, including the evidence of authority of the party presenting the CVR for transfer which authority may include if applicable a signature guarantee from an eligible guarantor institution participating in a signature guarantee program approved by the Securities Transfer Association.

Upon receipt of such written notice, the CVR Registrar shall, subject to its reasonable determination that the transfer instrument is in proper form notify the Company that it has received such written notice. Upon receipt of such notice from the CVR Registrar, the Company shall determine whether the transfer otherwise complies with the other terms and conditions of this Agreement (including the provisions of Section 2.2), and if the Company determines that it does so comply, the Company shall instruct the CVR Registrar in writing to register the transfer of the CVRs in the CVR Register and notify the Company of the same. All duly transferred CVRs registered in the CVR Register will be the valid obligations of the Company, evidencing the same right and will entitle the transferee to the same benefits and rights under this Agreement as those previously held by the transferor. No transfer of a CVR will be valid until registered in the CVR Register, and any transfer not duly registered in the CVR Register will be void and invalid. All costs and expenses related to any transfer or assignment of the CVRs (including the cost of any transfer tax) will be the responsibility of the transferor.

(d) A Holder (or an authorized representative thereof) may make a request to the CVR Registrar to change such Holder’s address of record in the CVR Register. Upon receipt of such request, the CVR Registrar will promptly record the change of address in the CVR Register.

Until such Reporting Certificate is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that no event has occurred that would require a CVR Payment.

If the Holder Representative timely delivers to the Company an Objection Notice, the Company and the Holder Representative shall attempt in good faith to resolve such matters within thirty (30) days after receipt of the same by the Company, and if unable to do so, the Company and the Holder Representative shall resolve any unresolved disputed in accordance with Section 8.11, which decision will be final and binding on the parties, absent manifest error. The Company shall, within ten (10) Business Days following the final determination of the Initial CVR Payment Amount or any CVR Payment Adjustment Amount, as applicable, pay such Initial CVR Payment Amount or CVR Payment Adjustment Amount to the Rights Agent (for the account of the Holders) by wire transfer of immediately available funds to such account as may be designated by the Rights Agent, and deliver a letter of instruction and other relevant information reasonably required by the Rights Agent.

To the extent that amounts are so withheld or paid over to or deposited with the relevant governmental entity, such withheld amounts will be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made. The Company will provide written withholding and payment instructions to the Rights Agent from time to time as applicable, and upon request of the Rights Agent, and the Rights Agent shall be fully protected and shall incur no liability in relying on such instructions. The Rights Agent shall have the right to withhold payment to a Holder if such Holder has not provided an IRS Form W-9 or other applicable Tax form to avoid or reduce such withholding amounts.

(g) Subject to prior execution and delivery by the Holder Representative of a reasonable and customary confidentiality and market stand-off agreement, the Company shall provide the Holder Representative with reasonable access during normal business hours and upon reasonable advance request to the books and records of the Company to the extent necessary to verify whether a CVR Transaction occurred prior to the CVR Expiration Date or the Company’s calculation of the Initial CVR Payment Amount or any CVR Payment Adjustment Amount, as applicable; it being understood that the Holder Representative’s rights under this Section 2.4(g) shall terminate upon the later of (i) the CVR Expiration Date or (ii) thirty (30) days after the delivery to the Holder Representative of a Reporting Certificate.

(a) The CVRs will not have any voting or dividend rights, and interest will not accrue on any amounts payable on the CVRs to any Holder.

6.1 Effect of Merger or Consolidation.

(a) Except as contemplated by the Acquisition, the Company will not consolidate with or merge into any other Person or sell, transfer or otherwise convey all or substantially all of its assets, in one or a series of related transactions, to any Person, unless:

(i) the Person formed by such consolidation or into which the Company is merged or the Person that acquires by sale, transfer or other conveyance, all or substantially all of the assets of the Company (the “Surviving Person”) expressly assumes payment (if and to the extent required hereunder) of amounts on all the CVRs and the performance of every duty and covenant of this Agreement on the part of the Company to be performed or observed; and

(ii) the Company has delivered to the Holder Representative and the Rights Agent an Officer’s Certificate, stating that such consolidation, merger, conveyance, transfer or lease complies with this Article VI and that all conditions precedent herein provided for relating to such transaction have been complied with.

(b) In connection with a Change of Control, the Company will have the right, but not the obligation, in its sole discretion, to redeem all, but not less than all of the outstanding CVRs, at any time from and after the public announcement of such Change of Control and ending on the thirtieth (30th) day following the consummation of the Change of Control for an aggregate redemption amount equal to the Target Payment Amount. In the event that the Company wishes to exercise its right pursuant to this Section 6.1(b), the Company shall provide a written notice of redemption (a “Redemption Notice”) to the Rights Agent and the Holder Representative, which Redemption Notice shall specify the date fixed for the redemption of the outstanding CVRs which date shall be not less than ten (10) Business Days nor more than twenty (20) Business Days following the delivery of the Redemption Notice to the Rights Agent and the Holder Representative (such date, the “Redemption Date”).

The Rights Agent shall pay to each Holder, such Holder’s pro rata share of the Target Payment Amount pursuant to the payment procedures specified in Section 2.4(d) and subject to Section 2.4(f), Section 2.4(h), and Section 2.4(i).

In all questions arising under this Agreement, the Holder Representative may rely on the advice of outside counsel, and the Holder Representative will not be liable to any Holder for anything done, omitted or suffered in good faith by Holder Representative based on such advice.

(c) The Holders will severally (on a pro rata basis, based on the number of CVRs held by each Holder), but not jointly, indemnify the Holder Representative and hold the Holder Representative harmless against any loss, liability or expense incurred without gross negligence, bad faith or willful misconduct on the part of the Holder Representative and arising out of or in connection with the acceptance or administration of the Holder Representative’s duties hereunder, including the reasonable fees and expenses of any legal counsel or other advisors reasonably retained by the Holder Representative, to the extent not reimbursed by the Company pursuant to Section 7.2(d).

Notice and a copy of the written consent appointing such Person must be delivered to the Company and the Rights Agent not less than ten (10) days prior to such appointment. Such appointment will be effective upon the later of the date indicated in the consent or the date ten (10) days after such consent is received by the Company and the Rights Agent.

7.4 Grant of Authority.

The provisions of this Article VII will be binding upon the executors, heirs, legal representatives, successors and assigns of each Holder, and any references in this Agreement to any Holder or the Holders will mean and include the successors to such Holder’s rights hereunder, whether pursuant to testamentary disposition, the laws of descent and distribution or otherwise.

Confidential Information constitutes trade secrets and is of great value to the owner (or its Affiliates). Confidential Information shall not include any information that is: (a) already known to the other party or its Affiliates at the time of the disclosure, provided that such prior knowledge can be substantiated by the written records of such party; (b) publicly known at the time of the disclosure or becomes publicly known through no wrongful act or failure of the other party; (c) subsequently disclosed to the other party or its Affiliates on a non-confidential basis by a third party not having a confidential relationship with the owner and which rightfully acquired such information; or (d) independently developed by one party without access to the Confidential Information of the other, provided that such independent development can be substantiated by the written records of such party. This Agreement, including all of its terms and conditions, will not be deemed to be Confidential Information and may be publicly disclosed by the Company; provided, that the fee schedule shall be considered Confidential Information.

(b) All Confidential Information of a party will be held in confidence by the other party with at least the same degree of care as such party protects its own confidential or proprietary information of like kind and import, but not less than a reasonable degree of care. Neither party will disclose in any manner Confidential Information of the other party in any form to any person or entity without the other party’s prior consent. However, each party may disclose relevant aspects of the other party’s Confidential Information to its officers, Affiliates, agents, subcontractors and employees to the extent reasonably necessary to perform its duties and obligations under this Agreement. Without limiting the foregoing, each party will implement such physical and other security measures and controls designed to protect (a) the security and confidentiality of Confidential Information; (b) against any threats or hazards to the security and integrity of Confidential Information; and (c) against any unauthorized access to or use of Confidential Information. To the extent that a party delegates any duties and responsibilities under this Agreement to an agent or other subcontractor, the party ensures that such agent and subcontractor are contractually bound to confidentiality terms consistent with the terms of this Section 8.12.

(c) In the event that any requests or demands are made for the disclosure of Confidential Information, other than requests to Rights Agent for stockholder records pursuant to standard subpoenas from state or federal government authorities (e.g., divorce and criminal actions), the party receiving such request will promptly notify the other party to secure instructions from an authorized officer of such party as to such request and to enable the other party the opportunity to obtain a protective order or other confidential treatment, unless such notification is otherwise prohibited by law or court order. Each party expressly reserves the right, however, to disclose Confidential Information to any person whenever it is advised by counsel that it may be held liable for the failure to disclose such Confidential Information or if required by law or court order
