As used herein, “Forward Agreements” means each of (a) the letter agreement dated the date hereof between the Company and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. International plc (the “MS Forward Counterparty”), acting through ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ as agent, and (b) the letter agreement dated the date hereof between the Company and ▇▇▇▇▇▇▇, Sachs (the “GS Forward Counterparty” and, together with the MS Forward Counterparty, the “Forward Counterparties”), in each case each relating to the forward sale by the Company, subject to the Company’s right to elect Physical Settlement, Cash Settlement or

Net Share Settlement (as each such term is defined in the relevant Forward Agreement), of a number of shares of common stock, par value $0.10 per share, of the Company (“Common Stock”) equal to the number of shares of Common Stock to be sold by the Forward Counterparty’s affiliated Forward Seller pursuant to this Agreement. The shares of Common Stock to be borrowed and sold by the Forward Sellers to the Underwriters as set forth in Schedule I are referred to as the “Firm Shares.” The Firm Shares of Common Stock to be purchased by the Underwriters and all or any part of the Additional Shares as set forth in Schedule I are hereinafter called, collectively, the “Shares.”

▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and ▇▇▇▇▇▇▇, ▇▇▇▇▇ are acting as representatives (the “Representatives”) of the several Underwriters in connection with the offering and sale of the Shares.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement, including a prospectus, (the file number of which is set forth in Schedule I hereto) on Form S-3, relating to the securities (the “Shelf Securities”), including the Shares, to be issued from time to time by the Company. The registration statement as amended to the date of this Agreement, including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A, 430B or 430C under the Securities Act of 1933, as amended (the “Securities Act”), is hereinafter referred to as the “Registration Statement”, and the related prospectus covering the Shelf Securities dated November 12, 2008 in the form first used to confirm sales of the Shares (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act) is hereinafter referred to as the “Basic Prospectus.” The Basic Prospectus, as supplemented by the prospectus supplement specifically relating to the Shares in the form first used to confirm sales of the Shares (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act) is hereinafter referred to as the “Prospectus,” and the term “preliminary prospectus” means any preliminary form of the Prospectus. For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act and “Time of Sale Prospectus” means the Basic Prospectus together with the free writing prospectuses, if any, each identified in Schedule I hereto. As used herein, the terms “Registration Statement,” “Basic Prospectus,” “preliminary prospectus,” “Time of Sale Prospectus” and “Prospectus” shall in each case include the documents, if any, incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act. If the Company has filed an abbreviated registration statement to register additional shares of Common Stock pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration

Any free writing prospectus that the Company is required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or behalf of or used or referred to by the Company complies or will comply in all material respects with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder.

(b) The applicable Forward Agreement has been duly authorized, executed and delivered by the Forward Counterparty that is an affiliate of such Forward Seller and constitutes a valid and binding agreement of such Forward Counterparty, enforceable against such Forward Counterparty in accordance with its terms, except to the extent that enforceability thereof may be limited by the Enforceability Exceptions.

3. Agreements to Sell and Purchase.

(a) (i) On the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, each Forward Seller and the Company (with respect to any Shares sold pursuant to Section 12 hereof), severally and not jointly, hereby agrees to sell to the several Underwriters, and each Underwriter, agrees, severally and not jointly, to purchase from each Forward Seller and the Company (with respect to any Shares sold pursuant to Section 12 hereof) the respective numbers of Firm Shares set forth opposite its name in Schedule II-A hereto at the purchase price set forth in Schedule I hereto (the “Purchase Price”).

(ii) The Underwriters shall have the right to purchase, pursuant to clause (A) or clause (B) below, as applicable, severally and not jointly, up to the number of Additional Shares set forth in Schedule I hereto at the Purchase Price less an amount per share equal to any dividends or distributions declared by the Company and payable on the Firm Shares but not payable on such Additional Shares (such reduced Purchase Price, the “Option Purchase Price”). The Representatives may exercise this right on behalf of the Underwriters in whole or in part by giving written notice not later than thirty (30) days after the date of the Prospectus. Any exercise notice shall specify the aggregate number of Additional Shares to be purchased by the Underwriters and the date on which such shares are to be purchased (the “Option Closing Date”). The Option Closing Date must be at least two business days after the written notice is given and may not be earlier than the closing date for the Firm Shares nor later than ten business days after the date of such notice. Following delivery of an exercise notice:

(A) The Company may, in its sole judgment, within one business day after such notice is given, execute and deliver to the applicable Forward Seller an additional forward agreement in the form attached hereto as Annex B with each Forward Counterparty (each such agreement, an “Additional Forward Agreement”) with respect to a number of Additional Shares which bears the same ratio to the aggregate number of Additional Shares being purchased as the number of Additional Forward Shares set forth opposite the name of such Forward Counterparty’s affiliated Forward Seller in Schedule II-B bears to the total number of Additional Forward Shares (subject to such adjustments to eliminate fractional shares as the Representatives may determine). Upon execution and delivery of an Additional Forward Agreement, the applicable Forward Counterparty shall promptly execute and deliver such Additional Forward Agreement to the Company, and upon such execution and delivery, and on the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, the affiliated Forward Seller and the Company (with respect to any Shares sold pursuant to Section 12 hereof), severally and not jointly, hereby agrees to sell to the several Underwriters, and each Underwriter, agrees, severally and not jointly, to purchase from such Forward Seller and the Company (with respect to any Shares sold pursuant to Section 12 hereof) such Additional Shares at the Option Purchase Price.

(B) To the extent the Company does not timely execute and deliver one or both of the Additional Forward Agreements pursuant clause (A) above, then on the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company hereby agrees to sell to the several Underwriters the number of Additional Shares underlying the Additional Forward Sale Agreement(s)

that were not so executed and delivered, and each Underwriter, agrees, severally and not jointly, to purchase from the Company such number of Additional Shares at the Option Purchase Price.

(iii) Additional Shares may be purchased as provided in Section 5 hereof solely for the purpose of covering over-allotments made in connection with the offering of the Firm Shares. On the Option Closing Date, each Underwriter agrees, severally and not jointly, to purchase from the Company or the Forward Sellers, as applicable, the number of Additional Shares (subject to such adjustments to eliminate fractional shares as the Representatives may determine) that bears the same proportion to the total number of Additional Shares as the number of Firm Shares set forth opposite its name in Schedule II-A hereto (or such number increased as set forth in Section 11 hereof) bears to the total number of Firm Shares.

(b) If all of the conditions to effectiveness set forth in Section 3 of the Forward Agreements are not satisfied on or prior to the Closing Date, each Forward Seller, individually, in its sole judgment, may choose not to borrow and deliver for sale the Firm Shares. In addition, in the event that, in the commercially reasonable judgment of a Forward Counterparty, its affiliated Forward Seller is unable to borrow and deliver for sale under this Agreement all of the Firm Shares deliverable by such Forward Seller or if, in such Forward Counterparty’s commercially reasonable judgment, its affiliated Forward Seller would entail a stock loan cost in excess of a rate equal to 200 basis points per annum, then such Forward Seller shall only be required to deliver for sale the aggregate number of shares of Common Stock that such Forward Seller is able to so borrow at or below such cost.

(c) To the extent that the Company has entered into an Additional Forward Agreement with a Forward Counterparty pursuant to Section 3(a)(ii)(A), if (i) the representations and warranties of the Company contained in Section 1 hereto are not true and correct as of the Option Closing Date, (ii) the Company has not performed all of the additional obligations required to be performed by it under this Agreement on or prior to the Option Closing Date and (iii) the conditions set forth in Section 6 hereto have not been satisfied (clauses (i)–(iii), together, the “Option Conditions”), then the affiliated Forward Seller, in its sole judgment, may choose not to borrow and deliver for sale the Additional Shares underlying such Additional Forward Agreement. In addition, in the event that, in the commercially reasonable judgment of such Forward Counterparty, its affiliated Forward Seller is unable to borrow and deliver for sale under this Agreement all of the Additional Shares underlying such Additional Forward Agreement or if, in such Forward Counterparty’s commercially reasonable judgment, its affiliated Forward Seller would entail a stock loan cost in excess of a rate equal to 200 basis points per annum, then such Forward Seller shall only be

required to deliver for sale the aggregate number of shares of Common Stock that such Forward Seller is able to so borrow at or below such cost.

(d) If a Forward Seller (i) does not, pursuant to Section 3(b), borrow and deliver for sale the total number of Firm Shares set forth opposite its name in Schedule I hereto or (ii) to the extent that its affiliated Forward Counterparty has entered into an Additional Forward Agreement with the Company pursuant to Section 3(a)(ii)(A), does not, pursuant to Section 3(c), borrow and deliver for sale the total number of Additional Shares underlying such Additional Forward Agreement, the Forward Seller will use its commercially reasonable efforts to notify the Company no later than 5:00 p.m., New York City time, on the first business day prior to the Closing Date or the Option Closing Date, as the case may be.

4. Public Offering. The Company and each Forward Seller are advised by the Representatives that the Underwriters propose to make a public offering of their respective portions of the Shares as soon after the Registration Statement and this Agreement have become effective as in the judgment of the Representatives is advisable. The Company and each Forward Seller are further advised by the Representatives that the Shares are to be offered to the public upon the terms set forth in the Prospectus.

5. Payment and Delivery. Payment for the Firm Shares shall be made to each Forward Seller (or, in the case of delivery by the Company in accordance with Section 12, to the Company) in Federal or other funds immediately available in New York City on the closing date and time set forth in Schedule I hereto, or at such other time on the same or such other date, not later than the fifth business day thereafter, as may be designated in writing by the Representatives.

The foregoing sentence shall not apply to (a) the Shares to be sold hereunder and under the Forward Agreements and any Additional Forward Agreements, (b) the grant or issuance by the Company of employee or director stock options or restricted stock in the ordinary course of business pursuant to plans currently in existence, which plans have been disclosed in writing the Underwriters prior to the date hereof or (c) the issuance by the Company of any shares of Common Stock upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof.

8. Covenants of the Underwriters. Each Underwriter severally covenants with the Company that it has not and will not take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

9. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless, without duplication, each Underwriter, each Forward Seller and each Forward Counterparty, each person, if any, who controls such Underwriter, Forward Seller or Forward Counterparty within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of such Underwriter, Forward Seller or Forward Counterparty within the meaning of Rule 405 under the Securities Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged 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 or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter, Forward Seller or Forward Counterparty furnished to the Company

in writing by such Underwriter, Forward Seller or Forward Counterparty through the Representatives expressly for use therein.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, each Forward Seller and each Forward Counterparty and their respective officers, directors, employees, agents and representatives, each person, if any, who controls any Forward Seller or Forward Counterparty within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter, Forward Seller or Forward Counterparty through the Representatives expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus or the Prospectus or any amendment or supplement thereto, it being understood that the only such information furnished by the Underwriters, the Forward Seller and the Forward Counterparties consists of the following: the language contained in the first full paragraph under the caption “Underwriting—Discounts and commissions” in the Time of Sale Prospectus.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 9(a) or 9(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonable fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be

reimbursed as they are incurred. Any such firm for any Underwriter, Forward Seller or Forward Counterparty, their respective officers, directors, employees, agents and representatives, any control persons of such Underwriter, Forward Seller or Forward Counterparty within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and any affiliate of such Underwriter Forward Seller or Forward Counterparty within the meaning of Rule 405 under the Securities Act, shall be designated in writing by the Representatives authorized to appoint counsel under this Section set forth in Schedule I hereto, and any such firm for the Company shall be designated in writing by the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than thirty (30) days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) To the extent the indemnification provided for in Section 9(a) or 9(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other hand from the offering of the Shares (ii) if the allocation provided by clause 9(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 9(d)(i) above but also the relative fault of the indemnifying party on the one hand and of the indemnified party on the other hand in connection with the statements or omissions that resulted in such losses,

claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company (which benefits shall include the proceeds that would be received by the Company upon Physical Settlement (as such term is defined in the Forward Agreements or the Additional Forward Agreements, as applicable) of the Forward Agreements and any Additional Forward Agreements on the Closing Date or the Option Closing Date, as applicable), the Forward Sellers and the Underwriters in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company (which benefits shall include the proceeds that would be received by the Company upon Physical Settlement (as such term is defined in the Forward Agreements or the Additional Forward Agreements, as applicable) of the Forward Agreements and any Additional Forward Agreements on the Closing Date or the Option Closing Date, as applicable), the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover of the Prospectus, and the spread received by the Forward Sellers, net of any costs associated therewith, as reasonably determined by the Forward Counterparties, bear to the aggregate initial public offering price of the Shares set forth in the Prospectus. The relative fault of the Company, the Forward Sellers and the Underwriters 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, the Forward Sellers or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

(e) The Company, the Forward Sellers and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters, on the one hand, or the Forward Sellers, on the other, were treated as a single entity, respectively, for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 9(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 9(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, no Underwriter shall 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 that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission; and, no Forward Seller

shall be required to contribute any amount in excess of the amount by which the spread received by the Forward Sellers, net of any costs associated therewith, as reasonably determined by the Forward Counterparties, exceeds the amount of any damages that such Forward Seller has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 9 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, Forward Seller or Forward Counterparty or any person controlling any Underwriter, Forward Seller or Forward Counterparty or any affiliate of any Underwriter, Forward Seller or Forward Counterparty or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

10. Termination. The Underwriters may terminate this Agreement by notice given by the Representatives to the Company and each Forward Seller, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, the NASDAQ Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade or other relevant exchanges, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the judgment of the Representatives, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

11. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule II-A bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 11 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Firm Shares are not made within thirty-six (36) hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case any of the Representatives, the Company or each Forward Seller shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on the Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on the Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on the Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If (i) this Agreement shall be terminated by the Underwriters, or any of them, pursuant to Section 10(ii), (ii) the Company fails or refuses to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company is unable to perform its obligations under this Agreement, or (iii) the Underwriters decline to purchase the Shares for any reason permitted under this Agreement other than due to a termination pursuant to Section 10(i), Section

Section 10(iii), Section 10(iv), Section 10(v) or the immediately preceding paragraph, the Company will reimburse the Underwriters and the Forward Sellers (without duplication) or such Underwriters and Forward Sellers as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters and Forward Sellers in connection with this Agreement or the offering contemplated hereunder.

12. Additional Issuance and Sale by the Company. (a) In the event that (i) all of the conditions to effectiveness set forth in Section 3 of the applicable Forward Agreement are not satisfied on or prior to the Closing Date or, in respect of any Additional Forward Agreement entered into pursuant to Section 3(a)(ii)(A), all the Option Conditions are not satisfied on the Option Closing Date, as the case may be, and a Forward Seller elects, pursuant to Section 3(b) or Section 3(c), not to deliver the Firm Shares or the Additional Shares, as applicable, or (ii) in the commercially reasonable judgment of a Forward Counterparty, its affiliated Forward Seller is unable to borrow and deliver for sale under this Agreement all of the Firm Shares or Additional Shares deliverable by such Forward Seller hereunder or if, in the Forward Counterparty’s commercially reasonable judgment, its affiliated Forward Seller would entail a stock loan cost in excess of a rate equal to 200 basis points per annum to borrow all of the Firm Shares and Additional Shares deliverable by such Forward Seller hereunder, the Company shall issue and sell in whole but not in part a number of shares of Common Stock equal to the number of shares that such Forward Seller does not deliver. The Representatives shall have the right to postpone the Closing Date or the Option Closing Date, as the case may be, for a period not exceeding one (1) business day in order to effect any required changes in any documents or arrangements.

(b) A Forward Seller shall have no liability whatsoever for any Shares it does not deliver to the Underwriters or any other party if such Forward Seller (i) elects, pursuant to Section 3(b) or Section 3(c) not to deliver Shares because all of the conditions to effectiveness set forth in Section 3 of the applicable Forward Agreement or the Option Conditions, as applicable, have not been satisfied or (ii) is unable to borrow and deliver for sale under this Agreement all of the Shares it is required to deliver hereunder or if, in the affiliated Forward Counterparty’s commercially reasonable judgment, it would entail a stock loan cost in excess of a rate equal to 200 basis points per annum to borrow all of the Firm Shares or Additional Shares, as the case may be, deliverable by such Forward Seller hereunder.

13. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the

extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company and the Underwriters with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) The Company acknowledges that in connection with the offering of the Shares: (i) the Underwriters, the Forward Sellers and the Forward Counterparties have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Underwriters, the Forward Sellers and the Forward Counterparties owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters, the Forward Sellers and the Forward Counterparties may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters, the Forward Sellers and the Forward Counterparties arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

14. Counterparts. This Agreement may be signed in two or more counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

15. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

16. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

17. Notices. All communications hereunder shall be in writing and effective only upon receipt. Notice to the Underwriters and each Forward Seller shall be delivered, mailed or sent to the Representatives at the address set forth in Schedule I hereto; and if to the Company shall be delivered, mailed or sent to the address set forth in Schedule I hereto.

If the foregoing is in accordance with your understanding, please indicate your acceptance of this Agreement by signing in the space provided below.

As Representatives of

the several Underwriters named

in Schedule I to the Underwriting Agreement

referred to below

Ladies and Gentlemen:

The undersigned understands that ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated (“▇▇▇▇▇▇ ▇▇▇▇▇▇▇”) and ▇▇▇▇▇▇▇, Sachs & Co. (“▇▇▇▇▇▇▇ ▇▇▇▇▇”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, Inc., a Delaware corporation (the “Company”), in connection with the letter agreement to be entered into between the Company and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. International plc, acting through ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ as agent and the letter agreement to be entered into between the Company and ▇▇▇▇▇▇▇ Sachs, providing for the public offering (the “Public Offering”) by the several Underwriters, including ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and ▇▇▇▇▇▇▇ ▇▇▇▇▇ (the “Underwriters”), of shares of the Common Stock, par value $0.10 per share of the Company (the “Common Stock”).

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and ▇▇▇▇▇▇▇ ▇▇▇▇▇ on behalf of the Underwriters, the undersigned will not, during the period commencing on the date hereof and ending 90 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be voluntarily made in

connection with subsequent sales of Common Stock or other securities acquired in such open market transactions, (b) transfers of shares of Common Stock or any security convertible into Common Stock as a bona fide gift; provided that in the case of any transfer pursuant to clause (b), (i) each donee shall sign and deliver a lock-up letter substantially in the form of this letter and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the restricted period referred to in the foregoing sentence, (c) transfers of shares of Common Stock or any security convertible into Common Stock on death, by will or intestacy, (d) dispositions to the undersigned’s immediate family or to any trust, partnership or other entity for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned or which entities are wholly owned by the undersigned; provided that in the case of any transfer or distribution pursuant to clause (d), (i) each transferee shall sign and deliver a lock-up letter substantially in the form of this letter and (ii) no filing under Section 16(a) reporting a reduction in beneficial ownership of shares of Common Stock shall be required or shall be voluntarily made during the restricted period referred to in the foregoing sentence, (e) the exercise of any stock options on a “cashless” or “net exercise” basis; provided that the shares of Common Stock acquired upon such exercise shall be subject to the restrictions set forth herein, (f) transfers or sales by the undersigned and all other persons subject to a lock-up letter entered into in connection with the Public Offering of up to an aggregate of 500,000 shares of Common Stock or any security convertible into Common Stock pursuant to any contract, instruction or plan complying with Rule 10b5-1 under the Exchange Act (a “10b5-1 Plan”) that has been entered into prior to the date of this agreement or (g) the entry by the undersigned into a new 10b5-1 Plan after the date of this agreement (a “New 10b5-1 Plan”); provided that any such New 10b5-1 Plan does not permit transfers or sales of Common Stock, and no transfers or sales of Common Stock pursuant to such plan occur, prior to the expiration of the restricted period.

In addition, the undersigned agrees that, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and ▇▇▇▇▇▇▇ ▇▇▇▇▇ on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 90 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

The undersigned understands that the Company and the Underwriters are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

If (i) the Public Offering has not been consummated by June 30, 2009 or (ii) the Underwriting Agreement is terminated pursuant to its terms, this agreement shall automatically terminate and the undersigned shall be released from its obligations hereunder.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an

Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

Very truly yours,

ANNEX A-1

OPINION OF ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP,

COUNSEL FOR THE COMPANY

1. The Company is a corporation under the general corporation law of the State of Delaware (“DGCL”) with corporate power and authority to own its properties and to conduct its business as described in the Registration Statement, the Preliminary Prospectus and the Prospectus. With your consent, based solely on certificates from public officials, we confirm that the Company is validly existing and in good standing under the laws of the State of Delaware and is qualified to do business in the following States: California, Florida, Kentucky and Minnesota.

2. The execution, delivery and performance of the Underwriting Agreement have been duly authorized by all necessary corporate action of the Company, and the Underwriting Agreement has been duly executed and delivered by the Company.

3. Each of the Forward Agreements has been duly authorized by all necessary corporate action of the Company, has been duly executed and delivered by the Company, and is the legally valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and equitable principles of general applicability.

4. The Shares, if any, to be issued and sold by the Company to the Underwriter pursuant to the Underwriting Agreement have been duly authorized by all necessary corporate action of the Company and, if issued to and paid for by you in accordance with the terms of the Underwriting Agreement, will be validly issued, fully paid and nonassessable and free of preemptive rights on the date hereof arising from the Company’s certificate of incorporation and bylaws

5. The Shares, if any, to be issued and sold by the Company to the Forward Counterparties pursuant to the Forward Agreements have been duly authorized by all necessary corporate action of the Company and, if issued to and paid for by the Forward Counterparties in accordance with the terms of the Forward Agreements, will be validly issued, fully paid and nonassessable and free of preemptive rights on the date hereof arising from the Company’s certificate of incorporation and bylaws.

6. The Registration Statement has become effective under the Act. With your consent, based solely on a telephonic confirmation by a member of the Staff of the Commission on May [ ], 2009, we confirm that no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceedings therefor have been initiated by the Commission. The Preliminary Prospectus has been filed in accordance with Rule 424(b) under the Act, the Prospectus has been filed in accordance with Rule 424(b) and 430B under the Act, and the specified issuer free writing prospectuses have been filed in accordance with Rule 433(d) under the Act.

7. The Registration Statement as of the date of the Prospectus, including the information deemed to be a part thereof pursuant to Rule 430B under the Act, and the

Prospectus, as of its date, each appeared on their face to be appropriately responsive in all material respects to the applicable form requirements for registration statements on Form S-3 under the Act and the rules and regulations of the Commission thereunder; it being understood, however, that we express no view with respect to Regulation S-T or the financial statements, schedules, other financial data included in, incorporated by reference in, or omitted from, the Registration Statement or the Prospectus. For purposes of this paragraph, we have assumed that the statements made in the Registration Statement and the Prospectus are correct and complete.

8. The statements in the Preliminary Prospectus under the caption “Description of Common Stock,” insofar as they purport to constitute a summary of the terms of the Shares (other than the number of shares outstanding), are accurate descriptions or summaries in all material respects.

9. The execution and delivery of the Underwriting Agreement, the Forward Agreements and the issuance and sale of the Shares by the Company pursuant to the Forward Agreements do not on the date hereof:

(i) violate the Company’s certificate of incorporation or bylaws; or

(ii) result in the breach of or a default under any of the agreements identified as an exhibit to such opinion or court or other governmental orders, writs, judgments or decrees specifically directed to the Company that were identified to us by an officer of the Company as material to the Company; or

(iii) violate any federal statute, rule or regulation or provision of the DGCL applicable to the Company; or

(iv) require any consents, approvals or authorizations to be obtained by the Company from, or any registrations, declarations or filings to be made by the Company with, any governmental authority under any federal statute, rule or regulation or provision of the DGCL applicable to the Company on or prior to the date hereof that have not been obtained or made.

We express no opinion as to federal or state securities laws, tax laws, antitrust or trade regulation laws, insolvency or fraudulent transfer laws, antifraud laws, the Bank Holding Company Act and other bank regulations, compliance with fiduciary duty requirements, margin regulations, NYSE or FINRA rules, pension and employee benefit laws, usury laws and environmental laws (without limiting other laws excluded by customary practice).

10. The Company is not, and immediately after giving effect to the sale of the Shares in accordance with the Underwriting Agreement and the application of the proceeds as described in the Prospectus under the caption “Use of Proceeds,” will not be required to be, registered as an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

11. Based on such facts and subject to the qualifications, assumptions and limitations set forth herein and in the Preliminary Prospectus and the Prospectus, we hereby confirm that the statements in the Preliminary Prospectus and the Prospectus under the caption “Material U.S. Federal Income Tax Consequences for non-U.S. Holders of Our Common Stock,”

insofar as such statements purport to constitute summaries of United States federal income tax law and regulations or legal conclusions with respect thereto, constitute accurate summaries of the matters described therein in all material respects.

In addition, such counsel shall provide a statement to the effect that such counsel has participated in conferences and telephone conversations with officers and other representatives of the Company, the independent public accountants for the Company and representatives of the Underwriters, during which the contents of the Registration Statement, the Preliminary Prospectus, any specified issuer free writing prospectus and the Prospectus (and portions of certain of the documents incorporated therein) and related matters were discussed and, although such counsel is not passing upon, and does not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, the Preliminary Prospectus, any specified issuer free writing prospectus, the Prospectus or the documents incorporated therein and has not made any independent check or verification thereof, during the course of such participation, no facts came to such counsel’s attention that caused them to believe that:

(i) the Registration Statement, as of the date of the Prospectus, including the information deemed to be a part of the Registration Statement pursuant to Rule 430B under the Act (together with the documents incorporated therein), contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, not misleading;

(ii) the Preliminary Prospectus, as of the Time of Sale (together with the documents incorporated therein at that date and any specified issuer free writing prospectus) contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; or

(iii) the Prospectus, as of its date or as of the Time of Sale (together with the documents incorporated therein at that date), contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that such counsel expresses no belief with respect to the financial statements, schedules or other financial data included or incorporated by reference in, or omitted from, the Registration Statement, the Preliminary Prospectus, any specified issuer free writing prospectus, the Prospectus, the documents incorporated by reference therein or any Form T-1.

ANNEX A-2

OPINION OF ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇,

GENERAL COUNSEL FOR THE COMPANY

After due inquiry, such counsel does not know of any legal or governmental proceedings pending or threatened to which the Company or any of its subsidiaries is a party or to which any of the properties of the Company or any of its subsidiaries is subject other than proceedings fairly summarized in all material respects in the Time of Sale Prospectus and proceedings which such counsel believes are not likely to have a material adverse effect on the Company and its subsidiaries, taken as a whole, or on the power or ability of the Company to perform its obligations under the Underwriting Agreement or the Forward Agreements, or to consummate the transactions contemplated by the Time of Sale Prospectus.

ANNEX A-3

IN-HOUSE INTELLECTUAL PROPERTY OPINION

A. To my knowledge, the Company owns or possesses, or can acquire on reasonable terms, all material intellectual property currently employed by it in connection with the business now operated by it, and the Company has not received any notice of infringement of, or conflict with, asserted rights of others with respect to any of the foregoing that, singly or in the aggregate, would reasonably be expected to have a material adverse effect on the Company and its subsidiaries, taken as a whole.

B. To my knowledge, no third party is infringing or misappropriating any intellectual property right owned or licensed by the Company or its subsidiaries except as would not, singly or in the aggregate, reasonably be expected to have a material adverse effect on the Company and its subsidiaries, taken as a whole.
