(2) Each Tagging Stockholder will be responsible for funding its proportionate share of any escrow arrangements in connection with the Proposed Sale and for its proportionate share of any withdrawals therefrom, including without limitation any such withdrawals that are made with respect to claims arising out of agreements, covenants, representations, warranties or other provisions relating the Proposed Sale that were made by the Tagging Stockholder. 6 (3) Each Tagging Stockholder will be responsible for its proportionate share of the reasonable fees, commissions and other out-of-pocket expenses (collectively, "COSTS") of the Proposed Sale to the extent not paid or reimbursed by the Company, the Proposed Transferee or another Person (other than the Selling Stockholder); PROVIDED that the Proposed Sale is consummated and the liability for such Costs shall not exceed the total purchase price received by such stockholder for such shares. The Selling Stockholder shall be entitled to estimate the Tagging Stockholders' proportionate share of such Costs and to withhold such amounts from payments to be made to the Tagging Stockholder at the time of closing of such Proposed Sale; PROVIDED that (i) such estimate shall not preclude the Selling Stockholder from recovering additional amounts from the Tagging Stockholder in respect of such Tagging Stockholder's proportionate share of such Costs and (ii) the Selling Stockholder shall reimburse the Tagging Stockholder to the extent actual amounts are ultimately less than the estimated amounts or any such amounts are paid by the Company, the Proposed Transferee or another Person (other than the Selling Stockholder).

If any holders of Company Capital Stock and Warrants are given an option as to the form and amount of consideration to be received, all holders of Company Capital Stock and Warrants shall be given the same option. In the event that any of the terms and/or conditions set forth in the notice are thereafter amended in any respect, the Selling Stockholder shall also give written notice of the amended terms and conditions of the Proposed Sale to the Company, and each Tagging Stockholder shall be permitted to cancel its exercise of its rights under this Section III upon delivery of written notice to the Company to such effect and shall be released from its obligation hereunder. Upon its receipt of any such notice or amended notice, the Company shall promptly, but in all events within three (3) Business Days of its receipt thereof, forward copies thereof to each of the Tagging Stockholders. The Selling Stockholder will deliver or cause to be delivered to each Tagging Stockholder copies of all transaction documents relating to the Proposed Sale promptly as the same become available.

The Tagging Stockholders will be entitled under this Section III to Transfer to the Proposed 7 Transferee the number of shares of Company Capital Stock and Warrants calculated in accordance with Section III(1).

The consummation of such proposed disposition shall be subject to the sole discretion of the Selling Stockholder, who shall have no liability or obligation whatsoever to any Tagging Stockholder participating therein other than to obtain for such Tagging Stockholder the same terms and conditions as those of the Selling Stockholder. Upon the consummation of any such sale, the Company (i) shall transfer to the Proposed Transferee a stock certificate or certificates representing the number of shares of Company Capital Stock and Warrants to be disposed of by any Tagging Stockholders and (ii) shall promptly thereafter remit to each Tagging Stockholder (i) that portion of the proceeds of the disposition to which such Tagging Stockholder is entitled by reason of such participation and (ii) a stock certificate representing any balance of shares of Company Capital Stock and Warrants that were not so disposed of (or all shares of Company Capital Stock and Warrants, in the event the proposed disposition is not consummated). (6) If any Tagging Stockholder exercises its rights under this Section III, the closing of the purchase of the Company Capital Stock and Warrants with respect to which such rights have been exercised will take place concurrently with the closing of the sale of the Selling Stockholder's Company Capital Stock and Warrants to the Proposed Transferee. If by the end of ninety (90) days following the date of delivery of the notice of the Proposed Sale provided by the Company pursuant to Section III(4), the Selling Stockholder and the Proposed Transferee have not completed the Proposed Sale, each Tagging Stockholder shall be released from its obligations under this Section III, and the Tag-Along Notices shall be null and void, and it shall be necessary for the terms of this Section III to be separately complied with in order to consummate such Proposed Sale pursuant to this Section III. SECTION IV. DRAG-ALONG RIGHTS. (1) So long as this Agreement remains in effect, if WCAS or any of its Designated Affiliates (collectively, the "DRAGGING STOCKHOLDER") receives an offer from a Person other than any of their Designated Affiliates (a "THIRD PARTY") to purchase (in a transaction of a type referred to in the first sentence of Section III(1)) at least a majority of the shares of Company Capital Stock then outstanding and such offer is accepted by the Dragging Stockholder, then each Schedule I Purchaser (other than WCAS), FFT Purchaser and each of their Permitted Transferees (collectively, the "DRAG-ALONG STOCKHOLDERS") hereby agrees that, if requested by the Dragging Stockholder, it will Transfer to such Third Party, subject to the other provisions of this Section IV, on the terms of the offer so accepted by the Dragging Stockholder, including, without limitation, time of payment, form and choice of consideration and adjustments to purchase price, 8 the number of shares of Company Capital Stock and Warrants equal to the number of shares of Company Capital Stock and Warrants owned by it multiplied by the percentage of the then outstanding shares of Company Capital Stock and Warrants to which the Third Party offer is applicable.

The Drag-Along Notice will set forth the number of shares of Company Capital Stock and Warrants proposed to be so Transferred, the name of the proposed Transferee or acquiring Person, the proposed amount and form of consideration (and if such consideration consists in part or in whole of property other than cash, the Dragging Stockholder will provide such information, to the extent reasonably available to the Dragging Stockholder, relating to such non-cash consideration as the Drag-Along Stockholders together may reasonably request in order to evaluate such non-cash consideration), the number of shares of Company Capital Stock and Warrants sought and the other terms and conditions of the offer. If any holders of Company Capital Stock and/or Warrants are given an option as to the form and amount of consideration to be received, all holders of Company Capital Stock and/or Warrants shall be given the same option. Each Drag-Along Stockholder (x) shall agree to the same covenants with respect to such Drag-Along Stockholders, as appropriate, as the Dragging Stockholder agrees to in connection with the Section IV Transfer; PROVIDED, HOWEVER, that the aggregate amount of liability of such Drag-Along Stockholder with respect to such covenants shall not exceed the proceeds to such Drag-Along Stockholder in connection with the Section IV Transfer and (y) shall make such representations and warranties concerning its title to the shares of Company Capital Stock and/or Warrants to be sold in connection with the Section IV Transfer and its authority to enter into and consummate the Section IV Transfer as the Dragging Stockholder makes, but shall not be required to make any other representations and warranties or indemnities other than in respect of its own representations and warranties. If a Dragging Stockholder does not request that the Drag-Along Stockholders participate in a Section IV Transfer, then each Stockholder shall have the right to participate in such proposed transfer in accordance with its rights under Section III above. (3) Each Drag-Along Stockholder will be responsible for funding its proportionate share of any escrow arrangements in connection with the Section IV Transfer and for its proportionate share of any withdrawals therefrom, including without limitation any such withdrawals that are made with respect to claims arising out of agreements, covenants, representations, warranties or other provisions relating the Section IV Transfer that were made by the Drag-Along Stockholder. (4) Each Drag-Along Stockholder will be responsible for its proportionate share of the Costs of the Section IV Transfer to the extent not paid or reimbursed by the 9 Company, the Third Party or another Person (other than the Dragging Stockholder); PROVIDED that such Section IV Transfer is consummated and the liability for such Costs shall not exceed the total purchase price received by such Drag-Along Stockholder for such shares and/or Warrants. The Dragging Stockholder shall be entitled to estimate the Drag-Along Stockholders' proportionate share of such Costs and to withhold such amounts from payments to be made to the Drag-Along Stockholder at the time of closing of the Section IV Transfer; PROVIDED that (i) such estimate shall not preclude the Dragging Stockholder from recovering additional amounts from the Drag-Along Stockholder in respect of such Drag-Along Stockholder's proportionate share of such Costs and (ii) the Dragging Stockholder shall reimburse the Drag-Along Stockholder to the extent actual amounts are ultimately less than the estimated amounts or any such amounts are paid by the Company, the Third Party or another Person (other than the Dragging Stockholder). If the Section IV Transfer is not consummated within 180 days from the date of the Drag-Along Notice, the Dragging Stockholder must deliver another Drag-Along Notice in order to exercise its rights under this Section IV with respect to such Section IV Transfer.

(6) The proceeds from such Section IV Transfer (and, in the case of a sale of less than all of the outstanding shares of Company Capital Stock and Warrants, the number of shares and Warrants to be sold by each Stockholder) shall be allocated among the Stockholders on a PRO RATA basis, based on the number of shares of Company Capital Stock and Warrants (treating all "in the money" options and warrants as the number of shares of Company Common Stock issuable upon the exercise thereof, less such number of shares of Company Common Stock and Warrants the aggregate fair market value of which (based on the value attributed in such sale) would be required to pay the aggregate exercise price therefor, and treating any shares of convertible preferred stock or debt of the Company on an "as-converted" basis) then held by each Stockholder.

To the extent that elections pursuant to this Section VI(2) shall not be made with respect to any securities included in an Eligible Offering within such 15-day period, then the Company may issue such securities, but only for consideration not less than, and otherwise on no less favorable terms to the Company than, those set forth in the Company's notice and only within 60 days after the end of such 15-day period.

(2) WCAS, FFT and their Designated Affiliates (the "OFFEREES") shall have the right, exercisable upon written notice to the Seller within 15 days after receipt of any Notice of Desire to Sell (the "OFFER NOTICE"), to offer to purchase any or all Subject Shares proposed to be sold by the Seller at a purchase price equal to the proposed purchase price specified in the Notice of Desire to Sell if so specified, or as proposed in the Offer Notice if not specified in the Notice of Desire to Sell, and otherwise on the terms and conditions specified in the Notice of Desire to Sell to the extent so specified and any additional terms and conditions proposed in the Offer Notice (collectively, including with respect to purchase price, the "OFFER TERMS"). Each Offer Notice shall state the number of shares to be purchased by the Offerees delivering such Offer Notice (the "PURCHASING STOCKHOLDERS") and that the Purchasing Stockholders will purchase such 12 shares within 45 days thereafter (or such longer period as is necessary to obtain any necessary consents or approvals or to otherwise comply with applicable law). In the event that more than one Person exercises its right to offer to purchase pursuant to this paragraph (2), the allocation among such Purchasing Stockholders of any shares actually sold pursuant to this paragraph (2) shall be as agreed by such Purchasing Stockholders; PROVIDED, HOWEVER, if the number of shares that the Purchasing Stockholders offer to purchase exceeds the number of Subject Shares and the Purchasing Stockholders do not agree on the allocation of the Subject Shares prior to the expiration of the 15-day period specified in this paragraph (2) then the Subject Shares shall be allocated ratably between Purchasing Stockholders based on the number of shares of Company Capital Stock owned by such Purchasing Stockholder on the date of such Offer Notice out of the total outstanding shares of Company Capital Stock on that date owned by all of the Purchasing Stockholders; PROVIDED FURTHER that any such Subject Shares allocated to the FFT Purchasers may be allocated among the FFT Purchasers as such parties may agree. (3) If the Offerees deliver, within the period specified in paragraph (2) above, an Offer Notice with respect to Subject Shares, the Seller shall sell such Subject Shares to such Purchasing Stockholders on the Offer Terms within the 45-day period specified in paragraph (2) above (or such longer period as is necessary to obtain any necessary consents or approvals or to otherwise comply with applicable law). Following the period specified in paragraph (2) above, the Seller may (subject to any other applicable restrictions hereunder) transfer such Subject Shares with respect to which no Offer Notice was received to any third party; PROVIDED that the Seller may not sell such shares with respect to which no Offer Notice was received to such third party on material terms that are the same as or more favorable, in the aggregate, to such third party than the material terms set forth in the Offer Terms, in the aggregate. Any such sale with respect to which definitive documentation is not entered into within 60 days after the expiration of the period specified in paragraph (2) above, or which is not consummated within 60 days of the execution of such definitive documentation (or such longer period as is necessary to obtain any necessary consents or approvals or to otherwise comply with applicable law) shall again be subject to the requirements of this Section VII. SECTION VIII. FINANCIAL AND OTHER INFORMATION; CONFIDENTIALITY. (1) Until the earlier of (i) the date of the first occurrence of a Public Offering and (ii) the date on which any Stockholder no longer holds at least 25% of the Company Capital Stock (including for purposes hereof any shares of Company Common Stock obtained through the conversion of such Stockholders' shares of Company Class A Common Stock) held by such Stockholder as of the Effective Date, the Company shall furnish to such Stockholder: (a) within 95 days after the end of each fiscal year of the Company, a consolidated balance sheet of the Company and its subsidiaries as of the end of such fiscal year and the related consolidated statements of operations, changes in stockholders' equity and consolidated statement of cash flows of the Company and its subsidiaries for the fiscal year then ended, together with supporting notes thereto, certified without 13 qualification as to scope of audit by a firm of independent certified public accountants of recognized national standing selected by the Board; (b) within 50 days after the end of each quarter in each fiscal year (other than the last quarter in each fiscal year), a consolidated balance sheet of the Company and its subsidiaries and the related consolidated statements of operations, changes in stockholders' equity and consolidated statement of cash flows of the Company and its subsidiaries for the quarter then ended, unaudited but certified by the principal financial officer of the Company, such balance sheet to be as of the end of such quarter and such statements of operations, changes in stockholders' equity and consolidated statement of cash flows to be for such quarter and for the period from the beginning of the fiscal year to the end of such quarter, in each case subject to normal year-end adjustments; (c) within 35 days after the end of each month in each fiscal year, a consolidated balance sheet of the Company and its subsidiaries and the related consolidated statement of operations for the month then ended, unaudited but certified by the principal financial officer of the Company, such balance sheet to be as of the end of such month and such statement of operations to be for such month and for the period from the beginning of the fiscal year to the end of such month, in each case subject to normal year-end adjustments; (d) as soon as practicable after the receipt thereof, the Company's annual budget; (e) as soon as practicable after the receipt thereof, a copy of any other financial information contained in the Company's monthly management reports to the extent such information is available; (f) promptly upon filing, copies of all registration statements, prospectuses, periodic reports and other documents filed by the Company with the Commission; (g) reasonable access during business hours to the books, records and properties of the Company and a reasonable opportunity to discuss the business and affairs of the Company with the Company's management; and (h) promptly, from time to time, such other information regarding the operations, business, affairs and financial condition of the Company or any subsidiary as such Stockholder may reasonably request; PROVIDED that each such Stockholder shall cause all Confidential Information relating to the Company to be held in strict confidence in accordance with the provisions of this Section VIII. After any Stockholder no longer holds 25% of the Company Capital Stock and or Warrants held by such Stockholder on the date hereof, but before the first occurrence of a Public Offering, the 14 Company shall only be obligated pursuant to this Section VIII(1) to furnish to such Stockholder one annual report per year containing at least the information described in (a) above. (2) Each Stockholder and Permitted Transferee agrees that it will not use at any time any Confidential Information (as defined below) of which any such Stockholder or any Permitted Transferee is or becomes aware except in connection with its investment in the Company. (3) Each Stockholder and Permitted Transferee further agrees that the Confidential Information will be kept strictly confidential and will not be disclosed by it or its Representatives (as defined below), except (i) as required by applicable law, regulation or legal process or in response to any inquiry from a regulatory authority having jurisdiction over such Stockholder, and only after compliance with Section VIII(4); PROVIDED that this clause (i) may not be relied upon to the extent any action is taken by a Stockholder or Permitted Transferee which requires such disclosure and, but for such action, such disclosure would not have been required) and (ii) that it may disclose the Confidential Information or portions thereof to those of its officers, employees, directors and representatives of its legal, accounting and financial advisors (the persons to whom such disclosure is permissible being "REPRESENTATIVES") who need to know such information in connection with the investment by the Stockholder and the Permitted Transferees in the Company; PROVIDED that such Representatives (x) are informed of the confidential and proprietary nature of the Confidential Information and (y) agree to be bound by and perform the provisions of this Section VIII. Each Stockholder agrees to be responsible for any breach of this Section VIII by its Representatives other than those Representatives who after the date hereof execute a separate confidentiality agreement with the Company (it being understood that such responsibility shall be in addition to and not by way of limitation of any right or remedy the Company may have against such Representatives with respect to any such breach). (4) If any Stockholder, Permitted Transferee or Representative becomes legally compelled (including by deposition, interrogatory, request for documents, subpoena, civil investigative demand or similar process) to disclose any of the Confidential Information, such Stockholder, Permitted Transferee or Representative shall provide the Company with prompt and, if legally permissible, prior written notice of such requirement to disclose such Confidential Information. Upon receipt of such notice, the Company may seek a protective order or other appropriate remedy. If such protective order or other remedy is not obtained, such Stockholder, Permitted Transferee or Representative agrees to disclose only that portion of the Confidential Information which is legally required to be disclosed and to take all reasonable steps to preserve the confidentiality of the Confidential Information; PROVIDED that the Stockholder is not required to incur any costs in connection therewith. In addition, such Stockholder, Permitted Transferee and Representative will not oppose any action (and will, if and to the extent requested by the Company and is legally permitted to do so, cooperate with and assist the Company, at the Company's expense and on a reasonable basis, in any reasonable action) by the Company to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Confidential Information. 15 (5) "CONFIDENTIAL INFORMATION" means oral and written information concerning the Company and its subsidiaries furnished to any Stockholder or Permitted Transferee by or on behalf of the Company (irrespective of the form of communication and whether such information is so furnished before, on or after the date hereof), and all analyses, compilations, data, studies, notes, interpretations, memoranda or other documents prepared by any Stockholder or Permitted Transferee or any Representative containing or based in whole or in part on any such furnished information. The term "Confidential Information" does not include any information which (i) at the time of disclosure or thereafter is generally available to the public (other than as a result of a disclosure directly or indirectly by any Stockholder, Permitted Transferee or Representative in violation hereof), (ii) is or becomes available to any Stockholder or Permitted Transferee on a nonconfidential basis from a source other than the Company or its advisors, provided that such source was not known by the Stockholders or Permitted Transferees to be prohibited from disclosing such information to it by a legal, contractual or fiduciary obligation owed to the Company or (iii) is already in the possession of any Stockholder or Permitted Transferee (other than information furnished by or on behalf of the Company). (6) Until the earlier to occur of (i) the tenth anniversary of the date of this Agreement and (ii) the date of first occurrence of a Public Offering, the Company shall allow non-voting observers (the "BOARD OBSERVERS" and each a "BOARD OBSERVER"), appointed as set forth in this Section VIII(6), to attend each and every meeting of the Board. During such period, (i) A.S.F. Co-Investment Partners, L.P. shall have the right to appoint one Board Observer and (ii) each of California Public Employees' Retirement System, California Teachers' Retirement System, Chase Equity Partners III, L.P., GS Private Equity Partners III, L.P., on behalf of itself and the other Affiliates of Goldman, Sachs & Co., and BT Capital Investors, L.P. shall have the right, on a rotating annual basis, to appoint the other Board Observers for a one year term. California Public Employees' Retirement System and California Teachers' Retirement System shall appoint the first two of such Board Observers to serve one-year terms. GS Private Equity Partners III, L.P., on behalf of itself and the other Affiliates of Goldman, Sachs & Co. that are parties hereto, Chase Capital Partners and BT Capital Investors, L.P. shall appoint the next three of such Board Observers to serve one-year terms following the expiration of the previous Board Observers' terms. It is understood that the number of Board Observers appointed pursuant to clause (ii) above shall alternate between two and three each year. The appointment and removal of each Board Observer shall be by written notice from the appropriate Stockholder to the Company and shall take effect upon the delivery of written notice thereof at the Company's registered office. Each Board Observer and each Stockholder that has the right to appoint a Board Observer shall receive copies of all notices, minutes, consents, and other materials that the Company provides to the members of the Board, PROVIDED, HOWEVER, that the Company reserves the right to exclude any of the Board Observers from access to any meeting or any materials if it is reasonably believed, upon advice of counsel, that such exclusion is necessary to preserve any privilege or to protect confidential information. Except to the extent so excluded, the Board Observers may participate in discussions of any and all matters brought before any meeting it attends as a non-voting observer. 16 SECTION IX. DURATION OF AGREEMENT. This Agreement (other than the provisions of Section VIII(2), VIII(3), VIII(4) and VIII(5)) shall terminate upon the earlier to occur of (1) the tenth anniversary of the Effective Date and (2) the consummation of (x) one or more Public Offerings by the Company of Common Stock having an aggregate offering price to the public of not less than $100,000,000, or (y) the sale, transfer or other disposition (including a distribution by a limited partnership to its partners) by the Schedule I Purchasers to persons or entities not required to become parties hereto of at least 75% of the shares of Company Common Stock held by the Schedule I Purchasers on the Effective Date. SECTION X. REGULATORY COMPLIANCE. (a) Regulatory Compliance Cooperation. (i) In the event that a Regulated Holder reasonably determines that it has a Regulatory Problem, the Company agrees to take all such actions as are reasonably requested by such Regulated Holder in order (A) to effectuate and facilitate any transfer by the Regulated Holder of any securities of the Company then held by the Regulated Holder to any Person designated by the Regulated Holder, (B) to permit the Regulated Holder (or any of its Affiliates) to exchange all or any portion of the voting Securities then held by such Person on a share-for-share basis for shares of a class of non-voting Securities of the Company, which non-voting Securities shall be identical in all respects to such voting Securities, except that such new Securities shall be non-voting and shall be convertible into voting Securities on such terms as are requested by the Regulated Holder and reasonably acceptable to the Company in light of regulatory considerations then prevailing, and (C) to continue and preserve the respective allocation of the voting interests with respect to the Company arising out of the Regulated Holder's ownership of voting Securities and/or provided for in this Agreement before the transfers and amendments referred to above (including entering into such additional agreements as are requested by the Regulated Holder to permit any Person(s) designated by the Regulated Holder to exercise any voting power which is relinquished by the Regulated Holder upon any exchange of voting Securities for non-voting Securities of the Company). If the Regulated Holder elects to transfer Securities of the Company to another Regulated Holder in order to avoid a Regulatory Problem, the Company and such other Regulated Holder shall enter into such mutually acceptable agreements as such other Regulated Holder may reasonably request in order to assist such Regulated Holder in complying with applicable laws and regulations to which it is subject. Such agreements may include restrictions on the redemption, repurchase or retirement of Securities of the Company that would result or be reasonably expected to result in such Regulated Holder's holding more voting securities or total securities (equity and debt) than it is permitted to hold under such laws and regulations. 17 (ii) In the event a Regulated Holder has the right to acquire any of the Company's securities from the Company or any other Person (as the result of a preemptive offer, pro rata offer or otherwise), and a Regulated Holder reasonably determines that it has a Regulatory Problem, at the Regulated Holder's request the Company will offer to sell to the Regulated Holder non-voting securities (or, if the Company is not the proposed seller, will arrange for the exchange of any voting securities for non-voting securities immediately prior to or simultaneous with such sale) on the same terms as would have existed had the Regulated Holder acquired the securities so offered and immediately requested their exchange for non-voting securities pursuant to subsection (i) above. (iii) In the event that any Affiliate of the Company ever offers to issue any of its Securities to the Regulated Holder, then the Company will cause such Affiliate to enter into agreements with the Regulated Holder substantially similar to this Section X. (b) DEFINITIONS. (i) "Regulated Holder" means any holder of the Company's Securities that is (or that is a subsidiary of a bank holding company that is) subject to the various provisions of Regulation Y of the Board of Governors of the Federal Reserve Systems, 12 C.F.R., Part 225 (or any successor to Regulation Y). (ii) "Regulatory Problem" means (i) any set of facts or circumstances wherein it has been asserted by any governmental regulatory agency (or Investor believes that there is a significant risk of such assertion) that such Person (or any bank holding company that controls such Person) is not entitled to hold, or exercise any material right with respect to, all or any portion of the Securities of the Company which such Person holds or (ii) when such Person and its Affiliates would own, control or have power (including voting rights) over a greater quantity of Securities of the Company than is permitted under any law or regulation or any requirement of any governmental authority applicable to such Person or to which such Person is subject. SECTION XI. REPRESENTATIONS AND WARRANTIES BY THE STOCKHOLDERS. Each Stockholder, severally and not jointly, represents and warrants to the Company and the other Stockholders as follows: (a) The execution, delivery and performance of this Agreement by such Stockholder will not violate any provision of applicable law, any order of any court or other agency of government, or any provision of any indenture, agreement or other instrument to which such Stockholder or any of his, her or its properties or assets is bound, or conflict with, result in a breach of or constitute (with due notice or lapse of time or both) a default under any such indenture, agreement or other instrument. 18 (b) This Agreement has been duly executed and delivered by such Stockholder, and when executed by the other parties hereto will constitute the legal, valid and binding obligation of such Stockholder, enforceable in accordance with its terms. SECTION XII. REPRESENTATIONS AND WARRANTIES BY THE COMPANY.

(b) This Agreement has been duly executed and delivered by the Company, and when executed by the other parties hereto will constitute the legal, valid and binding obligation of the Company, enforceable in accordance with its terms.
