It is understood that, subject to the conditions hereinafter stated, an aggregate of 6,000,000 shares of Common Stock (the "Firm Securities") will be sold to the several Underwriters named in Schedule I hereto (the "Underwriters") in connection with the public offering (the "Offering") and sale of such Firm Securities. Morgan Stanley & Co. LLC shall act as the representative (the "Representative") of the several Underwriters. In addition, as set forth below, the Company proposes to issue and sell to the Underwriters, upon the terms and conditions set forth in Section 3 hereof, an aggregate of up to 900,000 additional shares of Common Stock (the "Optional Securities"). The Firm Securities and the Optional Securities are hereinafter referred to as the "Securities."

This is to confirm the agreement concerning the purchase of the Securities from the Company by the Underwriters.

The Company has prepared and filed with the Securities and Exchange Commission (the "Commission") an "automatic shelf registration statement," as defined under Rule 405 ("Rule 405") under the Securities Act of 1933, as amended (the "Securities Act"), on Form S-3 (File No. 333-224469), covering the public offering and sale of certain securities of the Company, including the Securities, under the Securities Act and the rules and regulations promulgated thereunder (the "Securities Act Regulations"), which automatic shelf registration statement became effective under Rule 462(e) of the Securities Act Regulations ("Rule 462(e)"). The "Registration Statement," as of any time, means such registration statement as amended by any post-effective amendments thereto at such time, including the exhibits and any schedules thereto at such time, the documents incorporated or deemed to be incorporated by reference therein at such time pursuant to Item 12 of Form S-3 under the Securities Act and the documents otherwise deemed to be a part thereof as of such time pursuant to Rule 430B of the Securities Act Regulations ("Rule 430B"); provided, however, that the "Registration Statement" without reference to a time means such registration statement as amended by any post-effective amendments thereto as of the time of the first contract of sale for the Securities, which time shall be considered the "new effective date" of the Registration Statement with respect to the Securities within the meaning of paragraph (f)(2) of Rule 430B ("Rule 430B(f)(2)"), including the exhibits and schedules thereto at such time, the documents incorporated or deemed to be incorporated by reference therein at such time pursuant to Item 12 of Form S-3 under the Securities Act and the documents otherwise deemed to be a part thereof as of such time pursuant to Rule 430B. The base prospectus filed as part of such automatic shelf

registration statement, including the documents incorporated or deemed incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, is referred to herein as the "Base Prospectus". Each preliminary prospectus supplement to the Base Prospectus (including the Base Prospectus as so supplemented), that describes the Securities and the offering thereof, that omitted the Rule 430B Information and that was used prior to the filing of the final prospectus supplement referred to in the following sentence is herein called a "Preliminary Prospectus." Promptly after execution and delivery of this Agreement, the Company will prepare and file with the Commission a final prospectus supplement to the Base Prospectus relating to the Securities and the offering thereof in accordance with the provisions Rule 430B and Rule 424(b) of the Securities Act Regulations. Such final form of prospectus supplement (including the Base Prospectus as so supplemented), in the form filed with the Commission pursuant to Rule 424(b) is herein called the "Prospectus." Any reference herein to the Base Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to refer to include the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act as of the date of such prospectus. For purposes of this Agreement, all references to the Registration Statement, any Preliminary Prospectus or the Prospectus or any amendment or supplement thereto shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (or any successor system) ("EDGAR").

The aggregate of all pending legal or governmental proceedings to which the Company or any of its subsidiaries are a party or of which any of their respective properties, assets or operations are the subject which are not described in the Registration Statement, the General Disclosure Package and the Prospectus, including ordinary routine litigation incidental to the business, would not, singly or in the aggregate, result in a Material Adverse Effect.

The Company and its subsidiaries own or have a valid right to access and use all computer systems, networks, hardware, software, databases, websites and equipment used to process, store, maintain and operate data, information and functions used in connection with the business of the Company and its subsidiaries (the "Company IT Systems").

(z)Accounting Controls and Disclosure Controls. The Company and each of its subsidiaries maintain effective internal control over financial reporting (as defined under Rule 13-a15 and Rule 15d-15 of the Exchange Act Regulations) and a system of internal accounting controls sufficient to provide reasonable assurances that: (A) transactions are executed in accordance with management's general or specific authorization; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain accountability for assets; (C) access to assets is permitted only in accordance with management's general or specific authorization; (D) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences; and (E) the interactive data in eXtensible Business Reporting Language incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus fairly presents the required information and is prepared in accordance with the Commission's rules and guidelines applicable thereto.

No "reportable event" (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any "employee benefit plan" established or maintained by the Company, or any of its ERISA Affiliates.

The Company shall use its best efforts to prevent the issuance of any such stop order or prevention or suspension of such use. If the Commission shall enter any such stop order or order or notice of prevention or suspension at any time, the Company will use its best efforts to obtain the lifting of such order at the earliest possible moment, or will file a new registration statement and use its best efforts to have such new registration statement declared effective as soon as practicable.

the circumstances under which they were made or then prevailing, as the case may be, misleading or so that the Registration Statement or the Prospectus, as amended or supplemented, will comply with law.

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as required by this Agreement, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any time prior to, the First Closing Date or the Option Closing Date, as the case may be, by the Representative. Any such cancellation shall be without liability of the Underwriters to the Company. Notice of such cancellation shall be given to the Company in writing, or by telegraph or telephone and confirmed in writing.

7.Indemnification and Contribution.

(a)The Company agrees to indemnify, defend and hold harmless each Underwriter and any person who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the respective directors, officers, employees, agents and affiliates of each Underwriter from and against any loss, expense, liability, damage or claim (including the reasonable cost of investigation) which, jointly or

severally, any such Underwriter or controlling person may incur under the Securities Act, the Exchange Act or otherwise, insofar as such loss, expense, liability, damage or claim arises out of or is based upon (A) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereof), the General Disclosure Package, any Issuer Free Writing Prospectus or the Prospectus (the term Prospectus for the purpose of this Section being deemed to include the Base Prospectus included in the Registration Statement at the time it became effective and the Prospectus, all as amended or supplemented by the Company), (B) any omission or alleged omission to state a material fact required to be stated in any such Registration Statement, or necessary to make the statements made therein not misleading, (C) any omission or alleged omission from the General Disclosure Package, any Issuer Free Writing Prospectus, Base Prospectus or Prospectus of a material fact necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading; except only insofar as any such loss, expense, liability, damage or claim arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission of a material fact contained in and in conformity with information furnished in writing by the Underwriters through the Representative to the Company expressly for use in such Registration Statement, General Disclosure Package, Issuer Free Writing Prospectus, Base Prospectus or Prospectus.  The indemnity agreement set forth in this Section 7(a) shall be in addition to any liability which the Company or the Manager may otherwise have.

(b)Each Underwriter agrees, severally and not jointly, to indemnify, defend and hold harmless the Company, and its respective directors, officers that signed the Registration Statement, and any person who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, expense, liability, damage or claim (including the reasonable cost of investigation) which the Company or any such person may incur under the Securities Act, the Exchange Act or otherwise, insofar as such loss, expense, liability, damage or claim arises out of or is based upon (A) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereof), the General Disclosure Package, any Issuer Free Writing Prospectus, Base Prospectus, Prospectus or Prospectus, (B) any omission or alleged omission to state a material fact required to be stated in any such Registration Statement, or necessary to make the statements made therein not misleading, or (C) any omission or alleged omission from the General Disclosure Package, any such Issuer Free Writing Prospectus, Base Prospectus or Prospectus of a material fact necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading, but in each case only insofar as such untrue statement or alleged untrue statement or omission or alleged omission was made in such Registration Statement, General Disclosure Package, Issuer Free Writing Prospectus, Base Prospectus or Prospectus in reliance upon and in conformity with information furnished in writing by the Underwriters through the Representative to the Company expressly for use therein; and to reimburse the Company or any such director, officer, employee or controlling person for any legal and other expense reasonably incurred by the Company or any such director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The indemnity agreement set forth in this Section 7(b) shall be in addition to any liabilities that each Underwriter may otherwise have.

(c)Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of any claim or the commencement of any action or proceeding (including any governmental investigation), the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the claim or the commencement of that action; the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party for contribution or otherwise than under such subsection. If any such claim, action or proceeding shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party and shall pay as incurred the 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 at its own expense.  Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event  (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel,  (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 or (iii) the

indemnifying party shall have failed to assume the defense and employ counsel acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action.  Such firm shall be designated in writing by you in the case of parties indemnified pursuant to Section 7(a) and by the Company in the case of parties indemnified pursuant to Section 7(b).  If any settlement of any proceeding is effected with the written consent of the indemnifying party 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.  The indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding,  in form and substance reasonably satisfactory to such indemnified party and (ii) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d)If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under subsections (a) and (b) of this Section 7 in respect of any losses, expenses, liabilities, damages or claims referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, expenses, liabilities, damages or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities or (ii) if (but only if) the allocation provided by clause (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 (i) above but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, expenses, liabilities, damages or claims, as well as any other relevant equitable considerations.  The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company, on the one hand, bear to the underwriting discounts and commissions received by the Underwriters, on the other hand.  The relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company, on the one hand, or by the Underwriters, on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The amount paid or payable by a party as a result of the losses, claims, damages and liabilities referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any claim or action.

(e)The Company, on the one hand, and the Underwriters, on the other hand, agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in subsection (d)(i) and, if applicable (ii), above.  Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Securities purchased by such Underwriter.  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 Section 7 are several in proportion to their respective underwriting commitments and not joint. 

8.Substitution of Underwriters. If any Underwriter defaults in its obligation to purchase the number of Securities which it has agreed to purchase under this Agreement, the non-defaulting Underwriters shall be obligated to purchase (in the respective proportions which the number of Securities set forth opposite the name of each non-defaulting Underwriter in Schedule I hereto bears to the total number of Securities set forth opposite the names of all the non-defaulting Underwriters in Schedule I hereto) the Securities which the defaulting Underwriter agreed but failed to purchase; except that the non-defaulting Underwriters shall not be obligated to purchase any of the Securities if the total number of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase exceeds 10% of the total number of Firm Securities, and any non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of Securities set forth opposite its name in Schedule I hereto purchasable by it pursuant to the terms of Section 4 hereof. If the foregoing maximums are exceeded, (i) the non-defaulting Underwriters, and any other underwriters satisfactory to the Representative who so agree, shall have the right, but shall not be obligated, to purchase (in such proportions as may be agreed upon among them) all the Securities. If the non-defaulting Underwriters or the other underwriters satisfactory to the Representative do not elect to purchase the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company except for the payment of expenses to be borne by the Company and the Underwriters as provided in Section 5 hereof and the indemnity and contribution agreements of the Company and the Underwriters contained in Section 7 hereof.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have for damages caused by its default. If the other underwriters satisfactory to the Representative are obligated or agree to purchase the Securities of a defaulting Underwriter, either the Representative or the Company may postpone the First Closing Date for up to five full Business Days in order to effect any changes that may be necessary in the Registration Statement, the General Disclosure Package or the Prospectus or in any other document or agreement, and to file promptly any amendments or any supplements to the Registration Statement or the General Disclosure Package or the Prospectus which in the Representative' opinion may thereby be made necessary.

9.Effective Time and Termination.

(a)This Agreement shall become effective at the date and time this Agreement is executed and delivered to the parties hereto. Until this Agreement is effective, it may be terminated by the Company or by the Representative by giving notice as hereinafter provided to the Representative or by the Representative by giving notice as hereinafter provided to the Company, except that the provisions of Sections 6(q) and 7 hereof shall at all times be effective. For the purpose of this Section, the Securities shall be deemed to have been released for sale to the public upon release by the Representative of an electronic communication authorizing commencement of the offering the Securities for sale by the Underwriters or other securities dealers.

(b)This Agreement may be terminated by the Representative by giving notice as hereinafter provided to the Company, if (i) the Company shall have failed, refused or been unable, at or prior to each Closing Date, as applicable, to perform any agreement on its part to be performed hereunder unless the failure to perform any agreement is due to the default or omission by any Underwriter, (ii) any other condition of the obligations of the Underwriters hereunder is not fulfilled; (iii) trading in securities generally on the NYSE or Nasdaq shall have been suspended or minimum or maximum prices shall have been established on either of such exchanges or such market by the Commission or by such exchange or other regulatory body or governmental authority having jurisdiction; (iv) trading or quotation in any of the Company's securities shall have been suspended or limited by the Commission or by the NYSE or Nasdaq or other regulatory body of governmental authority having jurisdiction; (v) a general banking moratorium shall have been declared by Federal or state authorities; (vi) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred; (vii) there shall have been any material adverse change in general economic, political or financial conditions or if the effect of international conditions on the financial markets in the United States shall be such as, in the Representative's judgment, makes it inadvisable to proceed with the delivery of the Securities; or (viii) any attack on, outbreak or escalation of hostilities, declaration of war or act of terrorism involving the United States or any other national or international calamity or emergency if, in the Representative's judgment, the effect of any such attack, outbreak, escalation, declaration, act, calamity or emergency makes it impractical or inadvisable to proceed with the completion of the public offering or the delivery of the Securities. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Company or any Underwriter, except as otherwise provided in 7 hereof.

Any notice referred to above may be given at the address specified in Section 11 hereof in writing or by telegraph or telephone, and if by telegraph or telephone, shall be immediately confirmed in writing.

(c)This Agreement may also be terminated as provided in Section 8 hereof.

10.Survival of Indemnities, Contribution, Warranties and Representations. All representations, warranties, and agreements of the Company, Manager and the Underwriters herein or in certificates delivered pursuant hereto, and the agreements of the several Underwriters, the Company and the Manager contained in Section 7 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person thereof, or the Company or any of its officers, directors, or controlling persons, and shall survive delivery of, and payment for, the Securities to and by the Underwriters hereunder.
