The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time which may be made in connection with the offering and distribution of the Initial Securities upon notice by the Representatives to the Company and the Forward Sellers setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (an “Option Closing Date”) shall be determined by the Representatives, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Date, as hereinafter defined. Following delivery of a notice of exercise of the option to purchase additional shares by the Representatives to the Company and the Forward Sellers, the Company may, in its sole discretion, within one business day after such notice is given, execute and deliver to the Forward Sellers additional forward agreements, between the Company and the Forward Sellers (“Additional Forward Agreements”), providing for the forward sale by the Company of a number of shares of Common Stock equal to the aggregate number of Option Securities being purchased pursuant to the exercise of the option to purchase additional shares.

If the option is exercised as to all or any portion of the Option Securities, and the Company executes and delivers to the Forward Sellers Additional Forward Agreements, each of the Underwriters, acting severally and not jointly, will purchase from the Forward Sellers that proportion of the total number of Option Securities then being purchased which the number of

(d) Standby Option Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Underwriter, and each Underwriter, severally and not jointly, agrees to purchase from the Company the number of Standby Option Securities, if any, that bears the same proportion of the total number of Standby Option Securities then being purchased as the number of Initial Securities set forth in Exhibit 1 hereto opposite the name of such Underwriter bears to the total number of Initial Securities set forth in Exhibit 1 hereto; at the price per share set forth in subsection (b) of this Section 1, plus any additional number of Standby Option Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 9 hereof, subject in each case to such adjustments as the Representatives in their discretion shall make to eliminate any sales or purchases of fractional shares; provided, however, that the purchase price per share for any Standby Option Securities shall be reduced by an amount per share equal to any dividends or distributions declared by the Company and payable on the Initial Securities but not payable on the Option Securities (the “Standby Option Securities Purchase Price”).

(e) Failure to Borrow.

In connection with such issuance and sale by the Company, the Company and the Representatives shall have the right to postpone the Closing Date for a period not exceeding two business days in order to effect any required changes in any documents or arrangements. The shares of Common Stock sold by the Company to the Underwriters pursuant to this subsection (e) in lieu of Borrowed Initial Securities are referred to herein as the “Standby Initial Securities.”

(f) Failure to Borrow Option Securities.

6. Free Writing Prospectuses:

(a) The Company represents and agrees that, without the prior consent of the Representatives and the Forward Sellers, it has not made and will not make any offer relating to the Securities that would constitute a “free writing prospectus” as defined in Rule 405 under the Act, other than a Permitted Free Writing Prospectus and Limited Use Free Writing Prospectus; each Underwriter, severally and not jointly, represents and agrees

that, without the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Securities that would constitute a “free writing prospectus,” as defined in Rule 405 under the Act, other than a Permitted Free Writing Prospectus or Limited Use Free Writing Prospectus; any such free writing prospectus the use of which has been consented to by the Company and the Representatives is listed in Exhibit 2 hereto and herein called a “Permitted Free Writing Prospectus.”

(c) The Company and each Underwriter agree that if at any time following issuance of a Permitted Free Writing Prospectus, Limited Use Free Writing Prospectus or Written Testing-the-Waters Communication any event occurred or occurs as a result of which such Permitted Free Writing Prospectus, Limited Use Free Writing Prospectus or Written Testing-the-Waters Communication would conflict in any material respect with the information in the Registration Statement, the Pricing Prospectus or the Prospectus or include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, then (i) the party that first becomes aware of the foregoing will give prompt notice thereof to the Representatives and/ or the Company, as applicable, and, (ii) if requested by the Representatives or the Company, as applicable, the Company will prepare and furnish without charge a free writing prospectus or other document which will correct such conflict, statement or omission.

(e) Each Underwriter represents and agrees that any Testing-the-Waters Communications undertaken by it were with entities that such Underwriter reasonably believes are qualified institutional buyers as defined in Rule 144A under the Act or institutions that are accredited investors as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7), (a)(8), (a)(9), (a)(12) or (a)(13) under the Act.

Each Underwriter warrants and represents that the information furnished in writing to the Company through the Representatives for use in the Registration Statement, in the Basic Prospectus, in any Permitted Free Writing Prospectus, Limited Use Free Writing Prospectus, in the Prospectus, or in the Prospectus as amended

The warranties and representations of each Underwriter contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the Company or other person and shall survive the delivery of and payment for the Securities hereunder.

(b) Forward Sellers. Each Forward Seller represents and warrants to, and agrees with, each Underwriter and the Company, on the date of this Agreement, at the Closing Date and as of each Option Closing Date (in the case of a sale of Securities pursuant to Section 3(c) hereof) that:

(1) This Agreement has been duly authorized, executed and delivered by the Forward Sellers and, at the relevant Closing Date or Option Closing Date, the Forward Sellers shall have the full right, power and authority to sell, transfer and deliver the Borrowed Securities, as the case may be, to the extent that it is required to transfer such Borrowed Securities hereunder;

(2) The Forward Agreements and the Additional Forward Agreements (if any), as applicable, have been duly authorized, executed and delivered by the Forward Sellers and constitute valid and binding agreements of the Forward Sellers, enforceable against the Forward Sellers in accordance with their terms, except to the extent that enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws affecting the enforcement of creditors’ rights generally or by equitable principles relating to enforceability; and

(3) The Forward Sellers will, at the relevant Closing Date or Option Closing Date, have the free and unqualified right to transfer any Borrowed Securities, as the case may be, to the extent that it is required to transfer such Borrowed Securities hereunder, free and clear of any security interest, mortgage, pledge, lien, charge, claim, equity or encumbrance of any kind; and upon delivery of such Borrowed Securities and payment of the purchase price therefor as herein contemplated, assuming each of the Underwriters has no notice of any adverse claim, each of the Underwriters will have the free and unqualified right to transfer any such Borrowed Securities purchased by it from the Forward Sellers, free and clear of any security interest, mortgage, pledge, lien, charge, claim, equity or encumbrance of any kind.

8. Indemnification and Contribution:

(a) To the extent permitted by law, the Company agrees to indemnify and hold harmless each Underwriter and each Forward Seller, each of their respective affiliates participating in the offering of the Securities, and the employees, agents, officers and directors and each person, if any, who controls an Underwriter or any Forward Seller within the meaning of Section 15 of the Act, against any and all losses, claims, damages or liabilities, joint or several, to which an Underwriter or Forward Seller, they or any of you or them may

become subject under the Act or otherwise, and to reimburse the Underwriters, the Forward Sellers, they or any of you or them, for any legal or other expenses incurred by you or them in connection with defending any action, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any alleged untrue statement or untrue statement of a material fact contained in the Registration Statement, in the Basic Prospectus (if used prior to the effective date of this Agreement), in the Pricing Prospectus, in any Permitted Free Writing Prospectus or Limited Use Free Writing Prospectus, in any “issuer free writing prospectus” (as defined in Rule 433 under the Act), any Testing-the-Waters Communication or in the Prospectus, or if the Company shall furnish or cause to be furnished to the Underwriters any amendments or any supplements to the Pricing Prospectus or the Prospectus, in the Pricing Prospectus or the Prospectus as so amended or supplemented except to the extent that such amendments or supplements relate solely to securities other than the Securities (provided that if such Prospectus or such Prospectus, as amended or supplemented, is used after the period of time referred to in Section 4(b) hereof, it shall contain such amendments or supplements as the Company deems necessary to comply with Section 10(a) of the Act), or arise out of or are based upon any alleged omission or omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any such alleged untrue statement or omission, or untrue statement or omission which was made in the Registration Statement, in the Basic Prospectus, in the Pricing Prospectus, in any Permitted Free Writing Prospectus or Limited Use Free Writing Prospectus, “issuer free writing prospectus” (as defined in Rule 433 under the Act), any Testing-the-Waters Communication or in the Prospectus, or in the Prospectus as so amended or supplemented, in reliance upon and in conformity with information furnished in writing to the Company by or through the Representatives expressly for use therein. Each Underwriter and Forward Seller agrees promptly after its receipt of written notice of the commencement of any action in respect to which indemnity from the Company on account of its agreement contained in this Section 8(a) may be sought by any such Underwriter or Forward Seller, or by any person controlling any such Underwriter or Forward Seller, to notify the Company in writing of the commencement thereof, but the omission so to notify the Company of any such action shall not release the Company from any liability which it may have to an Underwriter, Forward Seller or to such controlling person otherwise than on account of the indemnity agreement contained in this Section 8(a). In case any such action shall be brought against an Underwriter, Forward Seller or any such controlling person and an Underwriter or Forward Seller shall notify the Company of the commencement thereof, as above provided, the Company shall be entitled to participate in, and, to the extent that it shall wish, including the selection of counsel (such counsel to be reasonably acceptable to the indemnified party), to direct the defense thereof at its own expense. In case the Company elects to direct such defense and select such counsel (hereinafter, Company’s counsel), an Underwriter, Forward Seller or any controlling person shall have the right to employ its own counsel, but, in any such case, the fees and expenses of such counsel shall be at such Underwriter’s, Forward Seller’s or controlling person’s expense unless (i) the Company has agreed in writing to pay such fees and expenses or (ii) the named parties to any such action (including any impleaded parties) include both an Underwriter, Forward Seller or any controlling person and the Company and such Underwriter, Forward Seller or any controlling person shall have been advised by its counsel that a conflict of interest between the Company and such Underwriter,

Forward Seller or any controlling person may arise (and the Company’s counsel shall have concurred in good faith with such advice) and for this reason it is not desirable for the Company’s counsel to represent both the indemnifying party and the indemnified party (it being understood, however, that the Company shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys for the Underwriters, Forward Sellers or any controlling person (plus any local counsel retained by the Underwriters, Forward Sellers or any controlling person in their reasonable judgment), which firm (or firms) shall be designated in writing by the Underwriters, Forward Sellers or any controlling person).

(b) Each Underwriter agrees, to the extent permitted by law, severally and not jointly, to indemnify, hold harmless and reimburse the Company, its respective directors and such of their officers as shall have signed the Registration Statement, the Forward Sellers, and each person, if any, who controls the Company or the Forward Sellers within the meaning of Section 15 of the Act, to the same extent and upon the same terms as the indemnity agreement of the Company set forth in Section 8(a) hereof, but only with respect to untrue statements or alleged untrue statements or omissions or alleged omissions made in the Registration Statement, or in the Basic Prospectus (if used prior to the effective date of this Agreement), or in the Pricing Prospectus, or in any Permitted Free Writing Prospectus or Limited Use Free Writing Prospectus, any Testing-the-Waters Communication, or in the Prospectus, or in the Prospectus as so amended or supplemented, in reliance upon and in conformity with information furnished in writing to the Company by the Representatives on behalf of such Underwriter expressly for use therein. Each of the Company and each Forward Seller agrees promptly after the receipt by it of written notice of the commencement of any action in respect to which indemnity from an Underwriter on account of an its agreement contained in this Section 8(b) may be sought by the Company, the Forward Sellers or by any person controlling the Company or one or more Forward Seller, as the case may be, to notify such Underwriter in writing of the commencement thereof, but the Company’s or Forward Seller’s omission so to notify such Underwriter of any such action shall not release it from any liability which it may have to the Company, the Forward Seller or to such controlling person otherwise than on account of the indemnity agreement contained in this Section 8(b).

(c) If recovery is not available or insufficient to hold the indemnified party harmless under Section 8(a) or Section 8(b) hereof for any reason other than as specified therein, the indemnified party shall be entitled to contribution for any and all losses, claims, damages, liabilities and expenses for which such indemnification is so unavailable or insufficient under this Section 8(c). In determining the amount of contribution to which such indemnified party is entitled, there shall be considered the portion of the proceeds of the offering of the Securities realized by the Company on the one hand (which proceeds shall include the proceeds to be received by the Company pursuant to the Forward Agreements and any Additional Forward Agreements, assuming, in each case, Physical Settlement (as defined therein) on the Effective Date (as defined therein)) and the Underwriters or the Forward Sellers on the other hand, the relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and any equitable

considerations appropriate under the circumstances. The Company, the Forward Sellers and the Underwriters agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation (even if the Underwriters were treated as one entity for such purpose) without reference to the considerations called for in the previous sentence. No Underwriter or any person controlling such Underwriter shall be obligated to contribute any amount or amounts hereunder which in the aggregate exceeds the total price of the Securities purchased by such Underwriter under this Agreement, less the aggregate amount of any damages which such Underwriter and its controlling persons have otherwise been required to pay in respect of the same claim or any substantially similar claim and no Forward Seller shall be obligated to contribute any amount in excess of the aggregate Spread under the relevant Forward Agreement or Additional Forward Agreement, as the case may be, net of any costs associated therewith, as reasonably determined by such Forward Seller. 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. An Underwriter’s and a Forward Seller’s respective obligations to contribute under this Section 8 is in proportion to its purchase obligation and not joint with any other Underwriter or Forward Seller.

(d) No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 8 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding 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 such indemnified party.

(e) In no event shall any indemnifying party have any liability or responsibility in respect of the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim effected without its prior written consent.

The agreements contained in this Section 8 hereof shall remain in full force and effect regardless of any investigation made by or on behalf of any person, and shall survive the delivery of and payment for the Securities hereunder.

9. Default of Underwriters: If any Underwriter under this Agreement shall fail or refuse (otherwise than for some reason sufficient to justify, in accordance with the terms hereof, the cancellation or termination of its obligations hereunder) to purchase and pay for the number of Securities which it has agreed to purchase and pay for hereunder, and the aggregate number of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of Securities, the other Underwriters shall be obligated severally in the proportions which the amounts of Securities set forth opposite their names in Exhibit 1 hereto bear to the aggregate number of Securities set forth opposite the names of all such

non-defaulting Underwriters, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on the terms set forth herein; provided that in no event shall the number of Securities which any Underwriter has agreed to purchase pursuant to Section 1 hereof be increased pursuant to this Section 9 by an amount in excess of one-ninth of such number of Securities without the written consent of such Underwriter. In the event of any such purchase, (a) the non-defaulting Underwriters or the Company shall have the right to fix as a postponed Closing Date a date not exceeding four full business days after the date specified in Section 2 and (b) the respective number of Securities to be purchased by the non-defaulting Underwriters shall be taken as the basis of their respective underwriting obligations for all purposes of this Agreement. If any Underwriter or Underwriters shall fail or refuse to purchase Securities and the aggregate number of Securities with respect to which such default occurs is more than one-tenth of the aggregate number of Securities then this Agreement shall terminate without liability on the part of any non-defaulting Underwriter; provided, however, that the non-defaulting Underwriters may agree, in their sole discretion, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on the terms set forth herein. In the event of any such termination, the Company shall not be under any liability to any Underwriter (except to the extent, if any, provided in Section 4(i) hereof), nor shall any Underwriter (other than an Underwriter who shall have failed or refused to purchase the Securities without some reason sufficient to justify, in accordance with the terms hereof, its termination of its obligations hereunder) be under any liability to the Company or any other Underwriter.

Nothing herein contained shall release any defaulting Underwriter from its liability to the Company or any non-defaulting Underwriter for damages occasioned by its default hereunder.

10. Termination of Agreement by the Underwriters: This Agreement may be terminated at any time prior to the Closing Date by the Representatives if, after the execution and delivery of this Agreement and prior to the Closing Date or the Option Closing Date, as applicable, in the Representatives’ reasonable judgment, the Underwriters’ ability to market the Securities shall have been materially adversely affected because:

(i)

trading in securities on the Nasdaq Global Select Market shall have been generally suspended by the Commission or by the Nasdaq Global Select Market or trading in the securities of the Company shall have been suspended by the Nasdaq Global Select Market, or

(ii)

there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other national or international calamity or crisis, or

(iii)

a general banking moratorium shall have been declared by Federal or New York State authorities.

If the Representatives elects to terminate this Agreement, as provided in this Section 10, the Representatives will promptly notify the Company and the Forward Sellers by telephone or by telex or facsimile transmission, confirmed in writing. If this Agreement shall not be carried out by any Underwriter for any reason permitted hereunder, or if the sale of the Securities to the Underwriters as

herein contemplated shall not be carried out because the Company is not able to comply with the terms hereof, the Company shall not be under any obligation under this Agreement and shall not be liable to any Underwriter or Forward Seller or to any member of any selling group for the loss of anticipated profits from the transactions contemplated by this Agreement (except that the Company shall remain liable to the extent provided in Sections 4(h), 4(i) and 8 hereof) and the Underwriters and Forward Sellers shall be under no liability to the Company nor be under any liability under this Agreement to one another.
