Section 3.               Covenants and Agreements. The Company covenants and agrees with the Underwriters that:

(a)           The Company will:

(i)            file, if required, the Prospectus and any amendment or supplement thereto with the Commission in the manner and within the time period required by Rule 424(b) under the Securities Act. During any time when a prospectus relating to the Securities is required to be delivered under the Securities Act, the Company (x) will comply with all requirements imposed upon it by the Securities Act, the Exchange Act and the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and the respective rules and regulations of the Commission thereunder to the extent necessary to permit the continuance of sales of or dealings in the Securities in accordance with the provisions hereof and of the Prospectus, as then amended or supplemented, and (y) will not file with the Commission the Base Prospectus or any amendment or supplement to such Base Prospectus (including the Prospectus or any Preliminary Prospectus), any amendment to the Registration Statement or any Free Writing Prospectus unless the Underwriters previously have been advised of, and furnished with a copy within a reasonable period of time prior to, the proposed filing and the Underwriters shall have given their consent to such filing, which shall not be unreasonably withheld. The Company will prepare and file with the Commission, in accordance with the rules and regulations of the Commission, promptly upon request by the Underwriters or counsel for the Underwriters, any amendments to the Registration Statement or amendments or supplements to the Prospectus that may be necessary or advisable, in the reasonable judgment of the Underwriters or their counsel, in connection with the distribution of the Securities by the Underwriters. The Company will advise the Underwriters, promptly after receiving notice thereof, of the time when the Registration Statement or any amendment thereto has been filed or become effective or the Prospectus or any amendment or supplement thereto has been filed and will provide evidence satisfactory to the Underwriters of each such filing or effectiveness.

4

(ii)           without charge, provide (y) to the Underwriters and to their counsel, an executed and a conformed copy of the Original Registration Statement and each amendment thereto or any Rule 462(b) Registration Statement (in each case including exhibits thereto) and (z) so long as a prospectus relating to the Securities is required to be delivered under the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Prospectus, the Prospectus and each Issuer Free Writing Prospectus or any amendment or supplement thereto as the Underwriters may reasonably request.

(iii)          advise the Underwriters, promptly after receiving notice or obtaining knowledge thereof, of (w) the issuance by the Commission of any stop order suspending the effectiveness of the Original Registration Statement or any amendment thereto or any order preventing or suspending the use of any Preliminary Prospectus or the Prospectus or any Free Writing Prospectus or any amendment or supplement thereto, (x) the suspension of the qualification of the Securities for offering or sale in any jurisdiction, (y) the institution, threatening or contemplation of any proceeding for any purpose identified in the preceding clause (w) or (x), or (z) any request made by the Commission for amending the Original Registration Statement, for amending or supplementing the Prospectus or for additional information. The Company will use its best efforts to prevent the issuance of any such stop order and, if any such stop order is issued, to obtain the withdrawal thereof as promptly as possible.

(b)           The Company will cooperate with the Underwriters in qualifying the Securities for offering and sale in each jurisdiction as the Underwriters shall designate including, but not limited to, pursuant to applicable state securities (“Blue Sky”) laws of certain states of the United States of America or other U.S. jurisdictions, and the Company shall maintain such qualifications in effect for so long as may be necessary in order to complete the placement of the Securities; provided, however, that the Company shall not be obliged to file any general consent to service of process or to qualify as a foreign corporation or as a securities dealer in any jurisdiction or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(c)           The Company agrees that, unless it obtains the prior written consent of each Underwriter, and each Underwriter, severally and not jointly, agrees with the Company that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a Free Writing Prospectus required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule III hereto, any electronic road show and term sheets relating to the Securities containing customary transaction announcement or pricing information. Any such Free Writing Prospectus consented to by the

5

Representatives or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.”  The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping. For the avoidance of doubt, Underwriter Free Writing Prospectuses that are not required to be filed by the Company with the Commission or retained by the Company under Rule 433 are permitted hereby.

(d)           If, at any time prior to the final date when a prospectus relating to the Securities is required to be delivered under the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Prospectus, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if for any other reason it shall be necessary at any time to amend the Registration Statement or amend or supplement the Prospectus to comply with the Securities Act, the Exchange Act or the Trust Indenture Act or the respective rules or regulations of the Commission thereunder or applicable law, the Company will promptly notify the Underwriters thereof and will promptly, at its own expense, but subject to the second sentence of Section 3(a)(i) hereof: (x) prepare and file with the Commission an amendment to the Registration Statement or amendment or supplement to the Prospectus which will correct such statement or omission or effect such compliance; and (y) supply any amended Registration Statement or amended or supplemented Prospectus to the Underwriters in such quantities as the Underwriters may reasonably request. If  there occurs an event or development as a result of which the Disclosure Package would include an untrue statement of material fact or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will notify promptly the Underwriters so that any use of the Disclosure Package may cease until it is amended or supplemented. The foregoing two sentences do not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company by any Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 11 hereof.

6

(g)           Neither the Company nor any of its affiliates, nor any person acting on behalf of any of them will, directly or indirectly, (i) take any action designed to cause or to result in, or that has constituted or which might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities or (ii) (x) sell, bid for, purchase, or pay anyone any compensation for soliciting purchases of, the Securities or (y) pay or agree to pay to any person any compensation for soliciting another to purchase any other securities of the Company.

(h)           During a period of 30 days from the date of the Prospectus, the Company will not, without the prior written consent of the Representatives, (i) directly or indirectly, 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 or otherwise transfer or dispose of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or file any registration statement under the Securities Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Stock, whether any such swap or transaction described in clause (i) or (ii) 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) any shares of Common Stock issued by the Company upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof and referred to in the Prospectus, (B) any shares of Common Stock issued or options to purchase Common Stock granted pursuant to employee benefit plans or employment agreements of the Company approved by the Board of Directors of the Company, (C) any shares of Common Stock issued pursuant to any non-employee dividend reinvestment plan or (D) any shares of Common Stock issued in mergers, acquisitions or other business combination transactions. Notwithstanding the foregoing, if (1) during the last 17 days of the 30-day restricted period the Company issues an earnings release or material news or a material event relating to the Company occurs; or (b) prior to the expiration of the 30 day restricted period, the Company announces that it will release earnings results during the 16 day period beginning on the last day of the 30 day period, the restrictions imposed by this agreement shall continue to apply until the expiration of the 18 day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. The Company shall promptly notify the Representatives and each person subject to the 30 day restricted period pursuant to a lock-up agreement described in Section 7(i) hereof of any earnings release, news or event that may give rise to an extension of the initial 30 day restricted period.

Section 4.               Expenses. The Company shall bear and pay all costs and expenses incurred incident to the performance of its obligations under this Agreement, whether or not the transactions contemplated herein are consummated or this Agreement is terminated pursuant to Section 8 hereof, including: (i) fees and expenses of preparation, issuance and delivery of this Agreement to the Underwriters and of the Indenture; (ii) the fees and expenses of its counsel, accountants and any other experts or advisors retained by the Company; (ii) fees and expenses incurred in connection with the registration of the Securities under the Securities Act and the

(x)                                 The Company meets the requirements for use of Form S-3 under the Securities Act and has filed with the Commission the Original Registration Statement (the file number of which is set forth in Schedule II hereto) on such Form, including a Base Prospectus, for registration under the Act of the offering and sale of the Securities, one or more amendments to such Registration Statement may have been so filed, and the Company has used a Preliminary Prospectus. Such Registration Statement, as so amended, became effective immediately upon filing thereof.

After the execution of this Agreement, the Company will file with the Commission pursuant to Rules 415 and 424(b)(2) or (5) a final supplement to the Base Prospectus included in such Registration Statement

8

relating to the Securities and the offering thereof, with such information as is required or permitted by the Securities Act and as has been provided to and approved by the Underwriters prior to the date hereof or, to the extent not completed at the date hereof, containing only such specific additional information and other changes (beyond that contained in the Base Prospectus and any Preliminary Prospectus) as the Company has advised you, prior to the date hereof, will be included or made therein.

(y)                               The Company meets the requirements for the use of Form S-3 under the Securities Act and has filed with the Commission the Original Registration Statement (the file number of which is set forth in Schedule II hereto) on such Form, including a Base Prospectus, for registration under the Securities Act of the offering and sale of the Securities, and one or more amendments to such Registration Statement, including a Preliminary Prospectus, may have been so filed. After the execution of this Agreement, the Company will file with the Commission a final prospectus supplement to the Base Prospectus in the form most recently included in an amendment to such Registration Statement (or, if no such amendment shall have been filed, in such Registration Statement), with such changes or insertions as are required by Rule 430A under the Securities Act or permitted by Rule 424(b) under the Securities Act, and as have been provided to and approved by the Underwriters prior to the execution of this Agreement.

(ii)           The Commission has not issued any order preventing or suspending the use of any Preliminary Prospectus or Issuer Free Writing Prospectus.

When the Prospectus or any amendment or supplement to the Prospectus is filed with the Commission pursuant to Rule 424(b) (or, if the Prospectus or such amendment or supplement is not required to be so filed, when the Registration Statement or the amendment thereto containing the Prospectus or such amendment or supplement to the Prospectus became effective) and on its date and on the Closing Date, the Prospectus, as amended or supplemented at any such time, (A) complied as to form or will comply in all material respects with the requirements of, the Securities Act, the Exchange Act, the Trust Indenture Act and the respective rules and regulations of the Commission thereunder and (B) did not or will not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which

9

they were made, not misleading. When the Registration Statement or any amendment thereto was effective and on the Closing Date, the Indenture did or will comply in all material respects with the requirements of the Trust Indenture Act and the rules and regulations of the Commission thereunder. The foregoing provisions of this paragraph (ii) do not apply to (1) that part of the Registration Statement which shall constitute the Statement of Eligibility and Qualification (Form T-1) under the Trust Indenture Act of the Trustee or (2) statements or omissions made in any Preliminary Prospectus, the Registration Statement or any amendment thereto or the Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by the Underwriters specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriters consists of the information described as such in Section 11 hereof.

(iii)          The Disclosure Package as of the Execution Time does not contain any 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 under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company by any Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 11 hereof.

(iv)          At the earliest time that (i) the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2)) of the Securities and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii)), the Company was not and is not an Ineligible Issuer (as defined in Rule 405), without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company be considered an Ineligible Issuer.

(v)           Each Issuer Free Writing Prospectus, if any, does not include any information that conflicts with the information contained in the Registration Statement, including any document incorporated therein and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. If there occurs an event or development as a result of which the Disclosure Package would include an untrue statement of material fact or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will notify promptly the Underwriters so that any use of the Disclosure Package may cease until it is amended or supplemented. The foregoing two sentences do not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company by any Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 11 hereof.

(ix)           Each document, if any, filed or to be filed pursuant to the Exchange Act and incorporated by reference in either the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) complied or will comply when so filed in all material respects with the Exchange Act and the applicable rules and regulations thereunder.

(x)            At the date hereof the Company is a “well-known seasoned issuer” as defined in Rule 405, including not having been and not being an “ineligible issuer” as defined in Rule 405.

Market manipulation

Taxes

(xxxiv)     The Company has filed all foreign, federal, state and local tax returns that are required to be filed or has requested extensions thereof (except in any case in which the failure so to file would not have a materially adverse effect on the Company and its subsidiaries, taken as a whole) and has paid all taxes required to be paid by it and any other assessment, fine or penalty levied against it (except in any case in which the failure to so pay would not have a Material Adverse Effect), to the extent that any of the foregoing is due and payable, except for any such assessment, fine or penalty that is currently being contested in good faith or as described in or contemplated by the Prospectus.

Section 6.               Indemnity.

(a)           The Company agrees to indemnify and hold harmless the Underwriters and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which any Underwriter or such controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon:

19

(i)            any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement or any amendment thereto, the Base Prospectus, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act or any amendment or supplement thereto, or

(ii)           the omission or alleged omission to state in the Registration Statement or any amendment thereto, the Base Prospectus, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act or any amendment or supplement thereto a material fact required to be stated therein or necessary to make the statements therein not misleading,

and will reimburse, as incurred, the Underwriters and each such controlling person for any legal or other costs or expenses reasonably incurred by the Underwriters or such controlling person in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement or any amendment thereto, the Base Prospectus, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by the Underwriters through the Representatives specifically for use therein. The indemnity provided for in this Section 6 shall be in addition to any liability that the Company may otherwise have. The Company will not, without the prior written consent of the Underwriters, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not the Underwriters or any person who controls the Underwriters is a party to such claim, action, suit or proceeding), unless such settlement, compromise or consent (A) includes an unconditional release of the Underwriters and such controlling persons from all liability arising out of such claim, action, suit or proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of the Underwriters or such controlling persons.

(b)           Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Company or any such director, officer or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement or any amendment thereto, the Base Prospectus, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement thereto or (ii) the omission or the alleged omission to state in the Registration Statement or any amendment thereto, the Base Prospectus any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus or

20

any amendment or supplement thereto a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by the Underwriters through the Representatives specifically for use therein, and, subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any legal or other expenses reasonably incurred by the Company or any such director, officer or controlling person in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or any action in respect thereof.

(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 paragraph (a) or (b) of this Section 6, such person (for purposes of this Section 6, the “indemnified party”) shall, promptly after receipt by such party of notice of the commencement of such action, notify the person against whom such indemnity may be sought (for purposes of this Section 6, the “indemnifying party”), but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise under paragraph (a) or (b) of this Section 6. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party; provided, however, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be one or more legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense of any such action and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 6 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated in writing by the Underwriters in the case of paragraph (a) of this Section 6, representing the indemnified parties under such paragraph (a) who are parties to such action or actions), or (ii) the indemnifying party does not promptly retain counsel satisfactory to the indemnified party, or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party. All fees and expenses reimbursed pursuant to this paragraph (c) shall be reimbursed as they are incurred. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be

21

liable for the costs and expenses of any settlement of such action effected by such indemnified party without the consent of the indemnifying party.

(d)           In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 6 is unavailable or insufficient, for any reason, to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the Offering or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and any Underwriter on the other shall be deemed to be in the same proportion as the total proceeds from the Offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by such Underwriter. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or such Underwriter, the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission, and any other equitable considerations appropriate in the circumstances. The Company 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 or by any other method of allocation that does not take into account the equitable considerations referred to above in this paragraph (d). Notwithstanding any other provision of this paragraph (d), no Underwriter shall be obligated to make contributions hereunder that in the aggregate exceed the total public offering price of the Securities purchased by such Underwriter under this Agreement, less the aggregate amount of any damages that such Underwriter has otherwise been required to pay in respect of the same or any substantially similar claim, and 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 Underwriters’ obligations to contribute pursuant to this paragraph (d) are several and not joint. For purposes of this paragraph (d), each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Underwriters, and each director of the Company, each officer of the Company who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company.

(e)           The remedies provided for in this Section 6 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.

22

Section 9.           Default by an Underwriter.    If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Firm Securities set forth opposite their names in Schedule I hereto bears to the aggregate amount of Firm Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the total aggregate amount of Securities set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date or Option Closing Date, as applicable, shall be postponed for such period, not exceeding five business days, as the nondefaulting Underwriters shall determine in order that the required changes in the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company or any nondefaulting Underwriter for damages occasioned by its default hereunder.

Section 10.         Reimbursement of Expenses.   If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 7 hereof is not satisfied or because of any termination pursuant to Section 8 hereof (other than by reason of a default by the Underwriters), the Company shall reimburse the Underwriters, upon demand, for all out-of-pocket expenses (including fees and disbursements of counsel) that shall have been incurred by it in connection with the proposed purchase and sale of the Securities.

Ladies and Gentlemen:

The undersigned understands that Citigroup Global Markets Inc. and ▇.▇. ▇▇▇▇▇▇ Securities Inc., as representatives of the several Underwriters (as defined below) (collectively, the “Representatives”), propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with iStar Financial Inc., a Maryland corporation (the “Company”), providing for the public offering (the “Public Offering”) by the several underwriters listed therein (the “Underwriters”), of notes convertible into shares (the “Shares”) of its Common Stock, par value $0.001 per share (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 the Representatives on behalf of the Underwriters, the undersigned will not, during the period commencing on the date hereof and ending 30 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 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 transactions relating to (a) shares of Common Stock or other securities acquired in open market transactions after the date of the final Prospectus related to the Public Offering, or (b) (i) transfers of shares of Common Stock or any security convertible into Common Stock by gift, will or intestacy, (ii) transfers of shares of Common Stock or any security convertible into Common Stock made by distribution to partners, members, shareholders, family members or a trust of the undersigned; provided, however, that in the case of a transfer pursuant to clause (b) above, it shall be a condition to the transfer that the transferee shall sign and deliver a lock-up letter substantially in the form of this letter. In addition,

notwithstanding the foregoing, the undersigned may offer, sell, pledge, contract to sell, (including any short sale), grant any option to purchase or otherwise dispose of any shares of Common Stock pursuant to any existing plans under Rule 10b5-1 of the Securities Exchange Act of 1934. 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.

Notwithstanding the foregoing, if (a) during the last 17 days of the 30-day restricted period the Company issues an earnings release or material news or a material event relating to the Company occurs; or (b) prior to the expiration of the 30-day restricted period, the Company announces that it will release earnings results during the 16 day period beginning on the last day of the 30 day period, the restrictions referred to above shall continue to apply until the expiration of the 18 day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

The undersigned hereby acknowledges that the Company will agree in the Underwriting Agreement to provide written notice of any event that would result in an extension of the 30-day restricted period pursuant to the previous paragraph to the undersigned and agrees that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned hereby further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this letter during the period from the date of this letter to and including the 34th day following the expiration of the 30-day restricted period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the 30-day restricted period (as such may have been extended pursuant to the previous paragraph) has expired.

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.

Whether or not the Public Offering actually occur depends on a number of factors, including market conditions. The 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.
