Dear Sirs,

The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the transaction entered into between us on the Trade Date specified below (the “Transaction”). This Confirmation constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below.

Each party further agrees that this Confirmation together with the Agreement evidence a complete binding agreement between Party A and Party B as to the subject matter and terms of the Transaction to which this Confirmation relates, and shall supersede all prior or contemporaneous written or oral communications with respect thereto. This Confirmation shall supplement, form a part of, and be subject to an agreement in the form of the 2002 ISDA Master Agreement (the “Agreement”) as if Party A and Party B had executed an agreement in such form on the Trade Date (but without any Schedule except for the election of the laws of the State of New York as the governing law), provided that the word “first” shall be replaced with the word “third” each time it occurs in Section 5(a)(i) of the Agreement. In the event of any inconsistency between provisions of that Agreement and this Confirmation, this Confirmation will prevail for the purpose of the Transaction to which this Confirmation relates. The parties hereby agree that no Transaction other than the Transaction to which this Confirmation relates shall be governed by the Agreement. For purposes of the 2002 Definitions, the Transaction is a Share Forward Transaction.

Party A and Party B each represents to the other that it has entered into the Transaction in reliance upon such tax, accounting, regulatory, legal, and financial advice as it deems necessary and not upon any view expressed by the other.

Party B’s obligations hereunder shall be subject to the condition precedent that Party A and each Affiliate of Party A that is an Underwriter (as such term is defined in the Underwriting Agreement) shall have performed, on or prior to the Effective Date, all of the obligations required to be performed by it prior to the Effective Date under the Underwriting Agreement.

Representations and Agreements of the Parties:

Additional Representations, Warranties and Agreements of Party B: Party B hereby represents and warrants to, and agrees with, Party A as of the date hereof that:

10

11

Covenant of Party B:

Subject to the provisions of “Private Placement Procedures” below, the parties acknowledge and agree that any Shares delivered by Party B to Party A on any Settlement Date will be newly issued Shares and when delivered by Party A (or an Affiliate of Party A) to securities lenders from whom Party A (or an Affiliate of Party A) borrowed Shares in connection with hedging its exposure to the Transaction will be freely saleable without further registration or other restrictions under the Securities Act, in the hands of those securities lenders, irrespective of whether such stock loan is effected by Party A or an Affiliate of Party A (provided that such Shares may be subject to resale restrictions if the status of any such securities lender would cause any such resale restrictions to apply by virtue of its share ownership in Party B, status as an “Affiliate” of Party B or otherwise). Accordingly, subject to the provisions of “Private Placement Procedures” below, Party B agrees that the Shares that it delivers to Party A on each Settlement Date will not bear a restrictive legend and that such Shares will be deposited in, and the delivery thereof shall be effected through the facilities of, the Clearance System.

12

Covenants of Party A:

Insolvency Filing:

Notwithstanding anything to the contrary herein, in the Agreement or in the Definitions, upon any Insolvency Filing in respect of the Issuer, the Transaction shall automatically terminate on the date thereof without further liability of either party to this Confirmation to the other party (except for any liability in respect of any breach of representation or covenant by a party under this Confirmation prior to the date of such Insolvency Filing).

The parties hereto agree and acknowledge that (1) at any point prior to any Insolvency Filing in respect of the Issuer, Party B shall have the unilateral right to elect Physical Settlement of the Transaction pursuant to the provisions set forth above under the heading “Settlement Terms”; and (2) the Transaction shall automatically terminate on the date of any Insolvency Filing pursuant to the provisions set forth in the immediately preceding paragraph solely to the extent that Party B failed to elect Physical Settlement of the Transaction pursuant to the provisions set forth above under the heading “Settlement Terms” prior to the relevant Insolvency Filing.

Extraordinary Dividends:

If an ex-dividend date for an Extraordinary Dividend occurs on or after the Trade Date and on or prior to the Maturity Date (or, if later, the last date on which Shares are delivered by Party B to Party A in settlement of the Transaction), Party B shall pay an amount, as determined by the Calculation Agent, in cash equal to the product of such Extraordinary Dividend and the Base Amount to Party A on the earlier of (i) the date on which such Extraordinary Dividend is paid by the Issuer to holders of record of the Shares or (ii) the Maturity Date. “Extraordinary Dividend” means the per Share amount of any cash dividend or distribution declared by the Issuer with respect to the Shares that is specified by the board of directors of the Issuer as an “extraordinary” dividend.

Acceleration Events:

The following events shall each constitute an “Acceleration Event”:

13

For purposes of clause (e) above, the “Share Amount” as of any day is the number of Shares that Party A and any of its Affiliates and any person whose ownership position would be aggregated with that of Party A, including any “group” (within the meaning of Section 13 of the Exchange Act) of which Party A is or may be deemed to be a part (Party A or any such person or group, a “Party A Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Party B that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership of under any Applicable Restriction, as determined by Party A in its good faith reasonable discretion. The “Post-Effective Limit” means a number of Shares equal to (x) the minimum number of Shares that would give rise to reporting or registration obligations (other than any filing under Section 13 of the Exchange Act and the rules and regulations thereunder, in each case, as in effect on the Trade Date) or other requirements (including obtaining prior approval from any person or entity) of a Party A Person,

14

or would result in an adverse effect on a Party A Person, under any Applicable Restriction, as determined by Party A in its good faith reasonable discretion (it being understood that reporting obligations under Section 13 or Section 16 of the Exchange Act and the rules and regulations thereunder, in each case, as in effect on the Trade Date, will not be deemed to have an adverse effect), minus (y) 1% of the number of Shares outstanding.

Materially Increased Costs:

Upon the occurrence of any Change in Law specified in clause (Y) of the definition thereof, Party A and Party B agree to negotiate in good faith for at least five Exchange Business Days (the “Amendment Period”) to amend this Confirmation to take account of the resulting “materially increased cost” as such phrase is used in clause (Y) of the definition of “Change in Law.” Such amendment may, if agreed by Party A and Party B, result in a Change in Law to which an Acceleration Event applies. If, after negotiating in good faith during the Amendment Period to so amend this Confirmation, Party A and Party B are unable to agree upon such an amendment, the relevant Change in Law specified in clause (Y) of the definition thereof shall constitute an Acceleration Event, notwithstanding any language in clause (d) under the heading “Acceleration Events” above to the contrary. The Calculation Agent may, in connection with a Termination Settlement following such Acceleration Event, reduce the Forward Price to compensate Party A for any “materially increased costs” incurred during the Amendment Period. Any Change in Law that results in Party A (or an Affiliate of Party A) incurring a Stock Loan Fee to hedge its exposure to the Transaction that is equal to or less than a rate equal to 200 basis points per annum shall not constitute a “materially increased cost” for purposes of clause (Y) of the definition of “Change in Law” (but may, for the avoidance of doubt, result in a reduction to the Forward Price pursuant to the provisions opposite the caption “Additional Adjustment” above).

Termination Settlement:

Upon the occurrence of any Acceleration Event, Party A shall have the right to designate, upon at least one Scheduled Trading Day’s notice, any Scheduled Trading Day following such occurrence to be a Settlement Date hereunder (a “Termination Settlement Date”) to which Physical Settlement shall apply, and to select the number of Settlement Shares relating to such Termination Settlement Date; provided that (i) in the case of an Acceleration Event arising out of an Ownership Event, the number of Settlement Shares so designated by Party A shall not exceed the number of Shares necessary to reduce the Share Amount to the Post-Effective Limit and (ii) in the case of an Acceleration Event arising out of a Stock Borrow Event, the number of Settlement Shares so designated by Party A shall not exceed the number of Shares as to which such Stock Borrow Event exists. If, upon designation of a Termination Settlement Date by Party A pursuant to the preceding sentence, Party B fails to deliver the Settlement Shares relating to such Termination Settlement Date when due or otherwise fails to perform obligations within its control in respect of the Transaction, it shall be an Event of Default with respect to Party B and Section 6 of the Agreement shall apply. If an Acceleration Event occurs during an Unwind Period relating to a number of Settlement Shares to which Cash Settlement or Net Share Settlement applies, then on the Termination Settlement Date relating to such Acceleration Event, notwithstanding any election to the contrary by Party B, Cash Settlement or Net Share Settlement shall apply to the portion of the Settlement Shares relating to such Unwind Period as to which Party A has unwound its hedge and Physical Settlement shall apply in respect of (x) the remainder (if any) of such Settlement Shares and (y) the Settlement Shares designated by Party A in respect of such Termination Settlement Date.

15

Private Placement Procedures:

Notwithstanding anything to the contrary contained in Section 9.11 of the 2002 Definitions, if Party B is unable to comply with the provisions of “Covenant of Party B” above because of a change in law or a change in the policy of the Securities and Exchange Commission or its staff, or Party A otherwise determines that in its reasonable opinion based on the advice of counsel any Settlement Shares to be delivered to Party A by Party B may not be freely returned by Party A or its Affiliates to securities lenders as described under “Covenant of Party B” above, then delivery of any such Settlement Shares (the “Restricted Shares”) shall be effected pursuant to Annex A hereto, unless waived by Party A; provided that Party A may not otherwise determine that the Settlement Shares are Restricted Shares based solely upon Party A not having borrowed and sold a number of Shares equal to the Base Amount on or before the Effective Date pursuant to the Registration Statement (as defined in the Underwriting Agreement) with delivery of the Prospectus (as defined in the Underwriting Agreement) if there has been no change in law or a change in the policy of the Securities and Exchange Commission or its staff.

Rule 10b5-1:

It is the intent of Party A and Party B that following any election of Cash Settlement or Net Share Settlement by Party B, the purchase of Shares by Party A during any Unwind Period comply with the requirements of Rule 10b5-1(c)(1)(i)(B) of the Exchange Act and that this Confirmation shall be interpreted to comply with the requirements of Rule 10b5-1(c).

Party B acknowledges that (i) during any Unwind Period Party B does not have, and shall not attempt to exercise, any influence over how, when or whether to effect purchases of Shares by Party A (or its agent or Affiliate) in connection with this Confirmation and (ii) Party B is entering into the Agreement and this Confirmation in good faith and not as part of a plan or scheme to evade compliance with federal securities laws including, without limitation, Rule 10b-5 promulgated under the Exchange Act.

Party B hereby agrees with Party A that during any Unwind Period Party B shall not communicate, directly or indirectly, any Material Non-Public Information (as defined herein) to any employee of Party A, other than Eric Natelson, Joseph Stoots, Theodore Finkelstein, Adrien Gotti, Yin Wu or any other designee confirmed in writing by Party A. For purposes of the Transaction, “Material Non-Public Information” means information relating to Party B or the Shares that (a) has not been widely disseminated by wire service, in one or more newspapers of general circulation, by communication from Party B to its shareholders or in a press release, contained in a public filing made by Party B with the Securities and Exchange Commission or otherwise disseminated in a manner permitted by the rules and regulations of the Securities and Exchange Commission and (b) a reasonable investor might consider to be of importance in making an investment decision to buy, sell or hold Shares. For the avoidance of doubt and solely by way of illustration, information should be presumed “material” if it relates to such matters as dividend increases or decreases, earnings estimates, changes in previously released earnings estimates, significant expansion or curtailment of operations, a significant increase or decline of orders, significant merger or acquisition proposals or agreements, significant new products or discoveries, extraordinary borrowing, major litigation, liquidity problems, extraordinary management developments, purchase or sale of substantial assets, or other similar information.

Maximum Share Delivery:

Notwithstanding any other provision of this Confirmation, in no event will Party B be required to deliver on any Settlement Date, whether pursuant to Physical Settlement, Net Share Settlement, Termination Settlement or any Private Placement Settlement, more than a number of Shares equal to 150% of the initial Base Amount to Party A, subject to reduction by the amount of any Shares delivered by Party B on any prior Settlement Date.

16

Transfer and Assignment:

Party A may assign or transfer any of its rights or delegate any of its duties hereunder to any Affiliate of Party A that has a long-term issuer rating or a rating for its long term, unsecured and unsubordinated indebtedness that is equal to or better than Party A’s credit rating at the time of such assignment or transfer so long as (a) such assignee or transferee is organized under the laws of the United States or any State thereof; (b) Party B will not be required to pay to such assignee or transferee an amount in respect of an Indemnifiable Tax under Section 2(d)(i)(4) of the Agreement greater than the amount in respect of which Party B would have been required to pay Party A in the absence of such assignment or transfer; (c) Party B will not receive a payment from which an amount has been withheld or deducted on account of a Tax under Section 2(d)(i) of the Agreement in excess of that which Party A would have been required to so withhold or deduct in the absence of such assignment or transfer, unless Party A would be required to pay to Party B amounts under Section 2(d)(i)(4) of the Agreement in respect of such Tax; and (d) no Event of Default, Potential Event of Default, Termination Event, Potential Adjustment Event or Acceleration Event will occur as a result of such assignment or transfer. Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Party A to purchase, sell, receive or deliver any Shares or other securities to or from Party B, Party A may designate any of its Affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform Party A’s obligations in respect of the Transaction and any such designee may assume such obligations. Party A shall be discharged of its obligations to Party B to the extent of any such performance.

Indemnity:

Party B agrees to indemnify Party A and its Affiliates and their respective directors, officers, agents and controlling parties (Party A and each such Affiliate or person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities, joint and several, incurred by or asserted against such Indemnified Party arising out of, in connection with, or relating to, any breach of any covenant or representation made by Party B in this Confirmation or the Agreement and will reimburse any Indemnified Party for all reasonable documented expenses (including reasonable documented legal fees and expenses) in connection with the investigation of, preparation for, or defense of any pending or threatened claim or any action or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto, but only to the extent that the relevant loss, claim, damage, liability or expense is found in a final and nonappealable judgment by a court of competent jurisdiction to have resulted from such breach. Party B will not be liable under this Indemnity paragraph to the extent that any loss, claim, damage, liability or expense is found in a final and nonappealable judgment by a court to have resulted from Party A’s gross negligence, fraud, willful misconduct or breach of this Confirmation or the Agreement.

17

No Collateral or Setoff:

Notwithstanding Section 6(f) or any other provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Party B hereunder are not secured by any collateral. Obligations under the Transaction shall not be set off against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and no other obligations of the parties shall be set off against obligations under the Transaction, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and each party hereby waives any such right of setoff. In calculating any amounts under Section 6(e) of the Agreement, notwithstanding anything to the contrary in the Agreement, (a) separate amounts shall be calculated as set forth in such Section 6(e) with respect to (i) the Transaction and (ii) all other Transactions, and (b) such separate amounts shall be payable pursuant to Section 6(d)(ii) of the Agreement.

Status of Claims in Bankruptcy:

Party A acknowledges and agrees that this confirmation is not intended to convey to Party A rights with respect to the transactions contemplated hereby that are senior to the claims of common stockholders in any U.S. bankruptcy proceedings of Party B; provided, however, that nothing herein shall limit or shall be deemed to limit Party A’s right to pursue remedies in the event of a breach by Party B of its obligations and agreements with respect to this Confirmation and the Agreement; and provided further, that nothing herein shall limit or shall be deemed to limit Party A’s rights in respect of any transaction other than the Transaction.

Limit on Beneficial Ownership:

Notwithstanding any other provisions hereof, Party A shall not be entitled to take delivery of any Shares deliverable hereunder (whether in connection with the purchase of Shares on any Settlement Date or any Termination Settlement Date, any Private Placement Settlement or otherwise) to the extent (but only to the extent) that, after such receipt of any Shares hereunder, and after taking into account any Shares or any other class of voting securities of Party B concurrently deliverable to Party A pursuant to the Base Confirmation, (i) the Share Amount would exceed the Post-Effective Limit or (ii) the Section 16 Percentage would exceed 7.5%. Any purported delivery hereunder shall be void and have no effect to the extent (but only to the extent) that, after such delivery, and after taking into account any Shares or any other class of voting securities of Party B concurrently deliverable to Party A pursuant to the Base Confirmation, (i) the Share Amount would exceed the Post-Effective Limit or (ii) the Section 16 Percentage would exceed 7.5%. If any delivery owed to Party A hereunder is not made, in whole or in part, as a result of this provision, Party B’s obligation to make such delivery shall not be extinguished and Party B shall make such delivery as promptly as practicable after, but in no event later than one Exchange Business Day after, Party A gives notice to Party B that, after such delivery, and after taking into account any Shares or any other class of voting securities of Party B concurrently deliverable to Party A pursuant to the Base Confirmation, (i) the Share Amount would not exceed the Post-Effective Limit and (ii) the Section 16 Percentage would not exceed 7.5%. The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Party A and any of its Affiliates or any other person subject to aggregation with Party A for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Party A is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the

18

equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day.

In addition, notwithstanding anything herein to the contrary, if any delivery owed to Party A hereunder is not made, in whole or in part, as a result of the immediately preceding paragraph, Party A shall be permitted to make any payment due in respect of such Shares to Party B in two or more tranches that correspond in amount to the number of Shares delivered by Party B to Party A pursuant to the immediately preceding paragraph.

Wall Street Transparency and Accountability Act:

In connection with Section 739 of the Wall Street Transparency and Accountability Act of 2010 (the “WSTAA”), the parties hereby agree that neither the enactment of the WSTAA or any regulation under the WSTAA, nor any requirement under the WSTAA or an amendment made by the WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the 2002 Definitions incorporated herein, or the Agreement (including, but not limited to, rights arising from any Acceleration Event or Illegality (as defined in the Agreement)).
