6.        (a) Each of the Company and each Selling Stockholder, severally and not jointly, represents and agrees that, without your prior consent, it has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Act;

(b)      The Underwriter represents and agrees that, without the prior consent of the Company, it has not made and will not make any offer relating to the Shares that would constitute a free writing prospectus;

(d)      The Company has complied and will comply in all material respects with the requirements of Rule 433 under the Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending; and the Company represents that it has satisfied and agrees that it will satisfy the conditions under Rule 433 under the Act to avoid a requirement to file with the Commission any electronic road shows;

(e)      The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Pricing Prospectus or the Prospectus, or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, the Company will give prompt notice thereof to you and, if requested by you, will prepare and furnish without charge to the Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, that this representation and warranty shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with the Underwriter Information.

7.        (a) The Company covenants and agrees with the Underwriter that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the registration of the Shares under the Act and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus and the Prospectus, including any amendments and supplements thereto, and the mailing and delivering of copies thereof to the Underwriter and dealers; (ii) the cost of printing or producing this Agreement, the Blue Sky Memorandum, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Shares; (iii) all expenses incurred in connection with the qualification of the Shares for offering and sale under state securities laws as provided in Section 5(c) hereof, including the fees and disbursements of counsel for the Underwriter in connection with such qualification and in connection with the Blue Sky survey up to a maximum of $7,500; (iv) all fees and expenses in connection with listing the Shares on the Exchange and the filing fees incident to, and the reasonable and incurred fees and disbursements of counsel for the Underwriter in connection with any required review by FINRA of the terms of the sale of the Shares; (v) the cost and charges of any transfer agent or registrar; (vi) the costs and expenses of the Company relating to presentations or meetings undertaken in connection with the marketing of the offering and sale of the Shares to prospective investors and the Underwriter’s sales force, including, without limitation, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations, travel, lodging and other expenses incurred by the officers of the Company and any such consultants, and the cost of any aircraft chartered in connection with the road show; (vii) fees and expenses for one counsel to the Selling Stockholders; and (viii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section.

8.        The obligations of the Underwriter hereunder, as to the Shares to be delivered at the Time of Delivery, shall be subject, in its discretion, to the condition that all representations and warranties and other statements of the Company and the Selling Stockholders herein are, at and as of the Time of Delivery, true and correct, the condition that the Company and the Selling Stockholders shall have performed all of its and their obligations hereunder theretofore to be performed, and the following additional conditions:

(i)         (A) The Company and its Significant Subsidiaries, taken as a whole, shall not have sustained since the date of the latest audited financial statements included or incorporated by reference in the Pricing Prospectus any loss or interference with their business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, in each case otherwise than as set forth or contemplated in the Pricing Prospectus, and (B) since the respective dates as of which information is given in the Pricing Prospectus there shall not have been any change in the capital stock, total debt or long-term debt of the Company or any of its subsidiaries or any change, or any development involving a prospective change, in or affecting the business, management, financial position or results of operations of the Company and its subsidiaries, taken as a whole, otherwise than as set forth or contemplated in the Pricing Prospectus, the effect of which, in any such case described in clause (A) or (B), is in your judgment so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares being delivered at the Time of Delivery on the terms and in the manner contemplated in the Prospectus;

(j)         On or after the Applicable Time, if the Company has debt securities that are accorded a rating by any “nationally recognized statistical rating organization”, as that term is defined by the Commission under Section 3 of the Exchange Act, (i) no downgrading shall have occurred in any such rating and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any such debt securities;

9.        (a) The Company will (i) indemnify and hold harmless the Underwriter and the Selling Stockholders against any losses, claims, damages or liabilities, joint or several, to which the Underwriter or Selling Stockholders may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof): (x) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (y) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and (ii) reimburse the Underwriter or each Selling Stockholder for any legal or other expenses reasonably incurred and documented by the Underwriter or such Selling Stockholder in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with the Underwriter Information or the Selling Stockholder Information.

(b)      Each of the Selling Stockholders, severally and not jointly, will (i) indemnify and hold harmless the Underwriter against any losses, claims, damages or liabilities, joint or several, to which the Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof): (x) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (y) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus, was made in reliance upon and in conformity with

17

Selling Stockholder Information; and (ii) reimburse the Underwriter for any legal or other expenses reasonably incurred and documented by the Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the liability of such Selling Stockholder pursuant to this subsection 9(b) and the contribution by such Selling Stockholder under subsection 9(e) shall not exceed the net proceeds (after deducting underwriting discounts and commissions, but without deducting expenses of the Company or the Selling Stockholders) received by such Selling Stockholder from the sale of the Shares sold by such Selling Stockholder hereunder (the “Selling Stockholder Net Proceeds”).

(c)      The Underwriter will (i) indemnify and hold harmless the Company and each Selling Stockholder against any losses, claims, damages or liabilities to which the Company or such Selling Stockholder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof): (x) arise out of or are based on an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (y) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, was made in reliance upon and in conformity with the Underwriter Information; and (ii) reimburse the Company and each Selling Stockholder for any legal or other expenses reasonably incurred and documented by the Company or such Selling Stockholder in connection with investigating or defending any such action or claim as such expenses are incurred.

(d)      Promptly after receipt by an indemnified party under subsection (a), (b) or (c) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection.  In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnified party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation.  No indemnifying party shall, without the written consent of the indemnified party effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or

18

claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(e)      If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders, on the one hand, and the Underwriter, on the other, from the offering of the Shares.  If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (d) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Stockholders, on the one hand, and the Underwriter, on the other, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations.  The relative benefits received by the Company or the Selling Stockholders, on the one hand, and the Underwriter, on the other, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Selling Stockholders bear to the total underwriting discounts and commissions received by the Underwriter, in each case as set forth on the cover page of the Prospectus.  The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Stockholders, on the one hand, or the Underwriter, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The Company, each of the Selling Stockholders and the Underwriter agree that it would not be just and equitable if contributions pursuant to this subsection (e) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (e).  The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred and documented by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this subsection (e), (i) the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and (ii) the contribution by any Selling Stockholder pursuant to this Section 9(e) and the liability of such Selling Stockholder under Section 9(b) shall not exceed the Selling Stockholder Net Proceeds. Each Selling Stockholder’s obligations to contribute under this Section 9(e) are several and limited in the manner and to the extent set forth in Section 9(b) above.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f)       The obligations of the Company and the Selling Stockholders under this Section 9 shall be in addition to any liability which the Company and the respective Selling Stockholders may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Underwriter within the meaning of the Act and each broker-dealer affiliate of the

Underwriter; and the obligations of the Underwriter under this Section 9 shall be in addition to any liability which the Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company or any Selling Stockholder within the meaning of the Act.

10.     The respective indemnities, agreements, representations, warranties and other statements of the Company, the Selling Stockholders and the Underwriter, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of the Underwriter or any controlling person of the Underwriter, or the Company or any officer or director or controlling person of the Company, or any Selling Stockholder or any controlling person of any Selling Stockholder, and shall survive delivery of and payment for the Shares.

11.     If any Shares are not delivered by or on behalf of any of the Selling Stockholders (each, a “Non-Delivering Selling Stockholder”) as provided herein, the Company will reimburse the Underwriter for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriter in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company and the Non-Delivering Selling Stockholders shall then be under no further liability to the Underwriter in respect of the Shares not so delivered except as provided in Sections 7 and 9 hereof.

12.     All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriter shall be delivered or sent by nationally recognized overnight courier, mail or facsimile transmission to the Underwriter at J.P. Morgan Securities LLC, 383 Madison Avenue, New York, New York 10179, Attention: Equity Syndicate Desk (4th Floor), facsimile number: (212) 622-8358; if to any Selling Stockholder shall be delivered or sent by nationally recognized overnight courier, mail or facsimile transmission to counsel for such Selling Stockholder at its address set forth in Schedule I hereto; and if to the Company shall be delivered or sent by nationally recognized overnight courier, mail or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Chief Legal Officer, with a copy to Proskauer Rose LLP, 2049 Century Park East, Suite 3200, Los Angeles, California 90025, facsimile number: (310) 557-2193, attention: Philippa M. Bond. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriter is required to obtain, verify and record information that identifies its clients, including the Company, which information may include the name and address of its clients, as well as other information that will allow the Underwriter to properly identify its clients.

13.     This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriter, the Company and the Selling Stockholders and, to the extent provided in Sections 9 and 10 hereof, the officers and directors of the Company and each person who controls the Company, any Selling Stockholder or the Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement.  No purchaser of any of the Shares from the Underwriter shall be deemed a successor or assign by reason merely of such purchase.

14.     Time shall be of the essence of this Agreement.  As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

15.     Each of the Company and each Selling Stockholder acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Company and the Selling Stockholders, on the one hand, and the

20

Underwriter, on the other, (ii) in connection therewith and with the process leading to such transaction the Underwriter is acting solely as a principal and not the agent or fiduciary of the Company or any Selling Stockholder, (iii) the Underwriter has not assumed an advisory or fiduciary responsibility in favor of the Company or any Selling Stockholder with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether the Underwriter has advised or is currently advising the Company or any Selling Stockholder on other matters) or any other obligation to the Company or to any Selling Stockholder except the obligations expressly set forth in this Agreement and (iv) it has consulted its own legal and financial advisors to the extent it deemed appropriate.  Each of the Company and each Selling Stockholder agrees that it will not claim that the Underwriter has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company or such Selling Stockholder, respectively, in connection with such transaction or the process leading thereto.

16.    This Agreement supersedes all prior agreements and understandings (whether written or oral) between either the Company or any of the Selling Stockholders, on the one hand, and the Underwriter, on the other hand, with respect to the subject matter hereof.

17.    THIS AGREEMENT AND ANY MATTERS RELATED TO THIS TRANSACTION SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF NEW YORK.  The Company agrees that any suit or proceeding arising in respect of this agreement or your engagement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in the City and County of New York, and the Company agrees to submit to the jurisdiction of, and to venue in, such courts.

18.    Each of the Company, the Selling Stockholders and the Underwriter hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

19.    This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

20.    Notwithstanding anything herein to the contrary, the Company and the Selling Stockholders are authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company and the Selling Stockholders relating to that treatment and structure, without the Underwriter imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

21.    If any term or other provision of this Agreement shall be held invalid, illegal or unenforceable, the validity, legality or enforceability of the other provisions of this Agreement shall not be affected thereby, and there shall be deemed substituted for the provision at issue a valid, legal and enforceable provision as similar as possible to the provision at issue.

22.    Except as otherwise expressly provided herein, the provisions of this Agreement may be amended or waived at any time only by the written agreement of the parties hereto. Any waiver,

21

permit, consent or approval of any kind or character on the part of any such holders of any provision or condition of this Agreement must be made in writing and shall be effective only to the extent specifically set forth in writing. The failure of any party hereto to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, nor in any way to affect the validity of this Agreement or any part hereof or the right of any party thereafter to enforce each and every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach.

If the foregoing is in accordance with your understanding, please sign and return to us four counterparts hereof, and upon the acceptance hereof by you, this letter and such acceptance hereof shall constitute a binding agreement among the Underwriter, the Company and each of the Selling Stockholders.
