Promptly from time to time to take such action as you may reasonably request to qualify the Securities and the shares of Class A Common Stock issuable upon conversion of the Securities for offering and sale under the securities laws of such jurisdictions as you may reasonably request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Securities, provided that in connection therewith the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction or to subject itself to taxation for doing business in any jurisdiction;

To furnish the Purchasers with electronic copies of the Preliminary Offering Memorandum and written and electronic copies of the Offering Memorandum and any amendment or supplement thereto in such quantities as you may reasonably request, and if, at any time prior to the completion of the distribution of the Securities by the Purchasers, any event shall have occurred as a result of which the Offering Memorandum as then amended or supplemented 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 when such Offering Memorandum is delivered, not misleading, or, if for any other reason it shall be necessary during such same period to amend or supplement the Offering Memorandum, to notify you and upon your request to prepare and furnish without charge to each Purchaser and to any dealer in securities as many written and electronic copies as you may from time to time reasonably request of an amended Offering Memorandum or a supplement to the Offering Memorandum which will correct such statement or omission or effect such compliance;

At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, for the benefit of holders from time to time of Securities, to furnish at its expense, upon request, to holders of Securities and prospective purchasers of Securities information (the “Additional Issuer Information”) satisfying the requirements of subsection (d)(4)(i) of Rule 144A under the Act;

For so long as the Company is subject to the reporting requirements of either Section 13 or 15(d) of the Exchange Act, to furnish to the holders of the Securities as soon as practicable after the end of each fiscal year, unless such information is otherwise publicly available on ▇▇▇▇▇, an annual report (including a balance sheet and statements of income, stockholders’ equity and cash flows of the Company and its consolidated subsidiaries certified by independent public accountants) and, as soon as practicable after the end of each of the first three quarters of each fiscal year (beginning with the fiscal quarter ending after the date of the Offering Memorandum), to make available to its stockholders consolidated summary financial information of the Company and its subsidiaries for such quarter in reasonable detail;

During the period of one year after such Time of Delivery, the Company will not, and will not permit any of its “affiliates” (as defined in Rule 144 under the Act) to, resell any of the Securities which constitute “restricted securities” under Rule 144 that have been reacquired by any of them (other than pursuant to a registration statement that has been declared effective under the Act);

To use the net proceeds received by the Company from the sale of the Securities pursuant to this Agreement substantially in the manner specified in the Pricing Disclosure Package under the caption “Use of Proceeds”;

To reserve and keep available at all times, free of preemptive rights, a number of shares of Class A Common Stock equal to the Maximum Number of Underlying Securities for the purpose of enabling the Company to satisfy any obligations to issue shares of its Class A Common Stock upon conversion of the Securities; and

To use its best efforts to have approved for listing on the New York Stock Exchange, subject to notice of issuance, a number of shares of Class A Common Stock equal to the Maximum Number of Underlying Securities.

(i)     The Company represents and agrees that, without the prior consent of the Representatives and their affiliates and any other person acting on its or their behalf (other than the Purchasers, as to which no statement is given) (x) it has not made and will not make any offer relating to the Securities that, if the offering of the Securities contemplated by this Agreement were conducted as a public offering pursuant to a registration statement filed under the Act with the Commission, would constitute an “issuer free writing prospectus,” as defined in Rule 433 under the Act (any such offer is hereinafter referred to as a “Company Supplemental Disclosure Document”) and (y) it has not solicited and will not solicit offers for, and have not offered or sold and will not offer or sell, the Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D other than any such solicitation listed on Schedule II(d) (each such solicitation, a “Permitted General Solicitation”; each written general solicitation document listed on Schedule II(d), a “Permitted General Solicitation Material”);

Unless otherwise agreed in writing by the Company and the Representatives (notwithstanding Section 17 hereof), the Company covenants and agrees with the several Purchasers 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 issue of the Securities and the shares of Class A Common Stock issuable upon conversion of the Securities and all other expenses in connection with the preparation, printing, reproduction and filing of the Preliminary Offering Memorandum and the Offering Memorandum and any amendments and supplements thereto and the mailing and delivering of copies thereof to the Purchasers and dealers; (ii) the cost of printing or producing any Agreement among Purchasers, this Agreement, the Indenture, the Capped Call Confirmations, the Securities, the Blue Sky Memorandum, closing documents (including any compilations thereof), Permitted General Solicitation Materials and any other documents in connection with the offering, purchase, sale and delivery of the Securities; (iii) all fees and expenses in connection with listing of the shares of Class A Common Stock issuable upon conversion of the Securities on the New York Stock Exchange; (iv) all expenses in

(i) Neither the Company nor any of its subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Pricing Disclosure Package any loss or interference with the business of the Company and its Subsidiaries, taken as a whole, 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, otherwise than as set forth or contemplated in the Pricing Disclosure Package, and (ii) since the respective dates as of which information is given in the Pricing Disclosure Package there shall not have been any change in the capital stock (other than as a result of (A) the issuance of shares of Common Stock upon the exercise of an option or warrant, the

On or after the Applicable Time (i) no downgrading shall have occurred in the rating accorded the Company’s debt securities by any “nationally recognized statistical rating organization”, as that term is defined by the Commission in Section 3(a)(62) of the Exchange Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s debt securities;

On or after the Applicable Time there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange or on the NASDAQ Global Market; (ii) a suspension or material limitation in trading in the Company’s securities on the New York Stock Exchange; (iii) a general moratorium on commercial banking activities declared by either Federal or New York State or the Commonwealth of Massachusetts authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war; or (v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in your judgment makes it impracticable or inadvisable to proceed with the offering or the delivery of the Securities being delivered at such Time of Delivery on the terms and in the manner contemplated in the Pricing Disclosure Package and the Offering Memorandum;

A number of shares of Class A Common Stock equal to the Maximum Number of Underlying Securities shall have been approved for listing on the New York Stock Exchange, subject to official notice of issuance;

The Company shall have obtained and delivered to the Purchasers executed copies of an agreement from each of the Company’s directors, executive officers and other securityholders listed on Schedule III hereto, in form and substance satisfactory to you, to the effect set forth on Annex III hereto;

The Purchasers shall have received an executed original copy of the Indenture;

(a) The Company will indemnify and hold harmless each Purchaser against any losses, claims, damages or liabilities, joint or several, to which such Purchaser may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Memorandum, the Pricing Offering Memorandum, the Pricing Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto, any Company Supplemental Disclosure Document, or any Permitted General Solicitation Material 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 not misleading, and will reimburse each Purchaser for any legal or other expenses reasonably incurred by such Purchaser 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 any Preliminary Offering Memorandum, the Pricing Offering Memorandum, the Pricing Disclosure Package, the Offering Memorandum or any such amendment or supplement, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material, in reliance upon and in conformity with written information furnished to the Company by any Purchaser through the Representatives expressly for use therein, which information is limited to the information set forth in Section 9(f).

Each Purchaser, severally and not jointly, will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Memorandum, the Pricing Offering Memorandum, the Pricing Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto, any Company Supplemental Disclosure Document, or any Permitted General Solicitation Material or arise out of or are based upon the omission or alleged omission to state therein a material fact or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Offering Memorandum, the Pricing Offering Memorandum, the Pricing Disclosure Package, the Offering Memorandum or any such amendment or supplement, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material, in reliance upon and in conformity with written information furnished to the Company by such Purchaser through the Representatives expressly for use therein, which information is limited to the information set forth in Section 9(f); and each Purchaser will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

Promptly after receipt by an indemnified party under subsection (a) or (b) 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 so 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 satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying 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 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.

If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) 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 on the one hand and the Purchasers on the other from the offering of the Securities. 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 (c) 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 on the one hand and the Purchasers 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 on the one hand and the Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (net of underwriting discounts and commissions but before deducting any other expenses) received by the Company bear to the total underwriting discounts and commissions received by the Purchasers, in each case as set forth in the Offering Memorandum. 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

The obligations of the Company under this Section 9 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of each Purchaser and each person, if any, who controls any Purchaser within the meaning of the Act and each broker-dealer affiliate of any Purchaser; and the obligations of the Purchasers under this Section 9 shall be in addition to any liability which the respective Purchasers 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 within the meaning of the Act.

The Purchasers severally confirm and the Company acknowledges and agrees that the statements appearing in the seventh paragraph, the third and fourth sentences of the eighth paragraph, ninth paragraph, second sentence of the tenth paragraph, sixteenth paragraph, seventeenth paragraph and nineteenth paragraph under the caption “Plan of Distribution” in the Pricing Disclosure Package and the Offering Memorandum constitute the only information concerning the Purchasers furnished in writing to the Company by or on behalf of the Purchasers expressly for use in any Preliminary Offering Memorandum, the Pricing Offering Memorandum, the Pricing Disclosure Package, the Offering Memorandum or any amendment or supplement thereto, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material.

If any Purchaser shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder at a Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Purchaser you do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Securities on such terms. In the event that, within the respective prescribed

If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Purchaser or Purchasers by you and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities to be purchased at such Time of Delivery, then the Company shall have the right to require each non-defaulting Purchaser to purchase the principal amount of Securities which such Purchaser agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Purchaser to purchase its pro rata share (based on the principal amount of Securities which such Purchaser agreed to purchase hereunder) of the Securities of such defaulting Purchaser or Purchasers for which such arrangements have not been made; but nothing herein shall relieve a defaulting Purchaser from liability for its default.

If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Purchaser or Purchasers by you and the Company as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities to be purchased at such Time of Delivery, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Purchasers to purchase Securities of a defaulting Purchaser or Purchasers, then this Agreement (or, with respect to a Second Time of Delivery, the obligations of the Purchasers to purchase and of the Company to sell the Option Securities) shall thereupon terminate, without liability on the part of any non-defaulting Purchaser or the Company, except for the expenses to be borne by the Company and the Purchasers as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Purchaser from liability for its default.

The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Purchasers, 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 any Purchaser or any controlling person of any Purchaser, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities.

If this Agreement shall be terminated pursuant to Section 10 hereof, the Company shall not then be under any liability to any Purchaser except as provided in Sections 7 and 9 hereof; but, if for any other reason, the Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Purchasers through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Purchasers in making preparations for the purchase, sale and delivery of the not so delivered Securities, but the Company shall then be under no further liability to any Purchaser except as provided in Sections 7 and 9 hereof.

In all dealings hereunder, you shall act on behalf of each of the Purchasers, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Purchaser made or given by you jointly or by the Representatives on behalf of you as the representatives.

This Agreement shall be binding upon, and inure solely to the benefit of, the Purchasers, the Company and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the Company or any Purchaser and each person who controls the Company or any Purchaser, 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 Securities from any Purchaser shall be deemed a successor or assign by reason merely of such purchase.

Time shall be of the essence of this Agreement.

The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the several Purchasers, on the other, (ii) in connection therewith and with the process leading to such transaction each Purchaser is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Purchaser has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Purchaser has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Purchaser, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Purchasers, or any of them, with respect to the subject matter hereof except as otherwise expressly set forth herein.

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 our 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.

The Company and each of the Purchasers hereby irrevocably waives, 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.

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 respective counterparts shall together constitute one and the same instrument.

Notwithstanding anything herein to the contrary, the Company (and the Company’s employees, representatives, and other agents) are authorized to disclose to any and all persons, the 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 relating to that treatment and structure, without the Purchasers’ 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 treatment” means U.S. federal and state income tax treatment, and “tax structure” is limited to any facts that may be relevant to that treatment.
