In addition to the foregoing, and as a condition to the Underwriters' purchase of Firm Shares from the Company pursuant to the preceding sentence, the Adviser agrees to pay the Underwriters an amount equal to $0.33 per shares (which represents the additional underwriting commissions that are being borne by the Adviser), to an account designated in writing by the Representatives.

(b) (i) The Selling Stockholder agrees to instruct the Company to issue and sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Selling Stockholder, at a purchase price per share of $13.87 (which reflects $14.30 per share (the public offering price) less $0.43 per share, which are the underwriting discounts and commissions that are being borne by the Selling Stockholder), the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereto, and (ii) in the event and to the extent that the Underwriters shall exercise the election to purchase Optional Shares as provided below, the Selling Stockholder agrees to sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Selling Stockholder, at a purchase price per share of $13.87, that portion of the number of Optional Shares as to which such election shall have been exercised (to be adjusted by you so as to eliminate fractional shares) determined by multiplying such number of Optional Shares by a fraction, the numerator of which is the maximum number of Optional Shares which such Underwriter is entitled to purchase as set forth opposite the name of such Underwriter in Schedule I hereto and the denominator of which is the maximum number of Optional Shares that all of the Underwriters are entitled to purchase hereunder.

(c) The Selling Stockholder hereby grants to the Underwriters the right to purchase at their election up to 900,000 Optional Shares, at the purchase price per share set forth in the paragraph above, for the sole purpose of covering sales of shares in excess of the number of Firm Shares, provided that the purchase price per Optional Share shall be reduced by an amount per share equal to any dividends or distributions declared by the Company and payable on the Firm Shares but not payable on the Optional Shares. Any such election to purchase Optional Shares may be exercised only by written notice from you to the Company and the Selling Stockholder, given within a period of 30 calendar days after the date of this Agreement, setting forth the aggregate number of Optional Shares to be purchased and the date on which such Optional Shares are to be delivered, as determined by you but in no event earlier than the First Time of Delivery (as defined in Section 6 hereof) or, unless you, the Company and the Selling Stockholder otherwise agree in writing, earlier than two or later than ten business days after the date of such notice.

The Company and the Selling Stockholder will cause the certificates representing the Shares to be made available for checking and packaging at least twenty-four hours prior to the Time of Delivery (as defined below) with respect thereto at the office of DTC or its designated custodian (the "Designated Office").

(g) On or after the Applicable Time, to the extent any of the NMF Funds have rated debt securities, (i) no downgrading shall have occurred in the rating accorded any of the NMF Funds' debt securities by any "nationally recognized statistical rating organization," as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of any of the NMF Funds' debt securities;

12. Indemnification.

(a) Each of the NMF Funds, jointly and severally, will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Additional Disclosure Item, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that none of the NMF Funds shall be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Additional Disclosure Item in reliance upon and in conformity with written information furnished to any of the NMF Funds by any Underwriter through the Representatives expressly for use therein.

(b) The Adviser and the Administrator, jointly and severally, will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Additional Disclosure Item, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred, provided, however, that the Adviser or the Administrator shall 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 an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Additional Disclosure Item in reliance upon and in conformity with written information furnished to any of the NMF Funds, the Adviser or the Administrator by any Underwriter through the Representatives expressly for use therein.

(c) The Selling Stockholder will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein 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 the Registration Statement, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by such Selling Stockholder expressly for use therein; and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that such Selling Stockholder shall 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 an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Pricing Prospectus or the Prospectus or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by any Underwriter through Goldman, Sachs & Co., Wells Fargo Securities, LLC and Morgan Stanley & Co. LLC expressly for use therein; provided further, that the liability of the Selling Stockholder under this subsection shall be limited to an amount equal to the aggregate net proceeds after underwriting commissions and discounts, but before expenses, to the Selling Stockholder from the sale of Shares sold by the Selling Stockholder hereunder.

(d) Each Underwriter, severally and not jointly, will indemnify and hold harmless each of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder against any losses, claims, damages or liabilities to which any of NMF Funds, the Adviser, the Administrator or the Selling Stockholder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Additional Disclosure Item, or arise out of or are based upon the omission or alleged omission to state therein 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 the Registration Statement, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Additional Disclosure Item, in reliance upon and in conformity with written information furnished to any of the NMF Funds, the Adviser, the Administrator or the Selling Stockholder by such Underwriter through the Representatives expressly for use therein; and will reimburse any of the NMF Funds, the Adviser, the Administrator or the Selling Stockholder for any legal or other expenses reasonably incurred by any of the NMF Funds, the Adviser, the Administrator or the Selling Stockholder in connection with investigating or defending any such action or claim as such expenses are incurred. Each of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder acknowledge that (i) the second and third sentences of the fifth paragraph related to concessions and reallowances and (ii) the eleventh, twelfth and thirteenth paragraphs related to stabilization, syndicate covering transactions and penalty bids under the heading "Underwriting" in the Registration Statement, the Pricing Prospectus or the Prospectus constitute the only information furnished in writing by or on behalf of the Underwriters

specifically for inclusion in the Registration Statement, the Pricing Prospectus or the Prospectus.

(e) Promptly after receipt by an indemnified party under subsection (a), (b), (c) or (d) above of notice of the commencement of any action, such 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 commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party under such subsection, except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(f) If the indemnification provided for in this Section 12 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a), (b), (c) or (d) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein but is otherwise applicable in accordance with its terms, then each indemnifying party 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 the relative benefits received by the NMF Funds, the Adviser, the Administrator and the Selling Stockholder on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (e) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder on the one hand and the Underwriters on the other in connection with the statements or omissions which 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 NMF Funds, the Adviser, the Administrator and the Selling Stockholder on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault 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 NMF Funds, the Adviser, the Administrator or the Selling Stockholder on the one hand or the Underwriters on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The NMF Funds, the Adviser, the Administrator and the Selling Stockholder and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (f) 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 above in this subsection (f). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (f) shall be deemed to include 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 subsection (f), 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 which such Underwriter 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations in this subsection (f) to contribute are several in proportion to their respective underwriting obligations and not joint.

(g) The obligations of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder under this Section 12 shall be in addition to any liability which each of the NMF Funds, the Adviser, the Administrator or the Selling Stockholder may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 12 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of each of the NMF Funds (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company or NMF LLC), the Adviser, the Administrator or the Selling Stockholder and to each person, if any, who controls any of the NMF Funds, the Adviser, the Administrator or the Selling Stockholder within the meaning of the Act. No party shall be entitled to indemnification under this Section 12 if such indemnification of such party would violate Section 17(i) of the Investment Company Act.

13. (a) If any Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder at a Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Shares, then the Company and the Selling Stockholder shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Shares on such terms. In the event that, within the respective prescribed periods, you notify the Company and the Selling Stockholder that you have so arranged for the purchase of such Shares, or the Company or Selling Stockholder notifies you that it has so arranged for the purchase of such Shares, you, the Company or the Selling Stockholder shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in your opinion may thereby be

made necessary. The term "Underwriter" as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Company and the Selling Stockholder as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, then the Selling Stockholder shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Company and the Selling Stockholder as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, or if the Selling Stockholder shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Second Time of Delivery, the obligations of the Underwriters to purchase and of the Selling Stockholder to sell the Optional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company, the Selling Stockholder and the Underwriters as provided in Section 10 hereof and the indemnity and contribution agreements in Section 12 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

14. The respective indemnities, agreements, representations, warranties and other statements of each of the NMF Funds, the Adviser, the Administrator, the Selling Stockholder and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or any of the NMF Funds, or the Selling Stockholder, or any officer or director or controlling person of any of the NMF Funds, or any controlling person of the Selling Stockholder, and shall survive delivery of and payment for the Shares.

15. If this Agreement shall be terminated pursuant to Section 13 hereof, each of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder shall not then be under any liability to any Underwriter except as provided in Sections 10 and 12, hereof; provided, if for any other reason, other than the occurrence of an event provided in Section 11(h) hereof, any Shares are not delivered by or on behalf of the Company as provided herein, each of the NMF Funds, jointly and severally, will reimburse the Underwriters through you for their allocable portion of all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered by the NMF Funds, but each of the NMF Funds shall then be under no further liability to any Underwriter except as provided in Sections 10 and 12 hereof; provided, further, if for any other reason, other than the occurrence of an event provided in Section 11(h) hereof, any Shares are not delivered by or on behalf of the Selling Stockholder as provided herein, the Selling Stockholder will reimburse the Underwriters through you for its allocable portion of all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel,

reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered by the Selling Stockholder, but the Selling Stockholder shall then be under no further liability to any Underwriter, except as provided in Sections 10 and 12 hereof.

16. In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by you jointly or by Goldman, Sachs & Co., Wells Fargo Securities, LLC or Morgan Stanley & Co. LLC on behalf of you as the representatives.

All statements, requests, notices and agreements hereunder shall be in writing, and:

(i) if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to you as the Representatives in care of Goldman, Sachs & Co., 200 West Street, New York, New York 10282, Attention: Registration Department; Wells Fargo Securities, LLC, 375 Park Avenue, New York, New York 10152, Attention: Equity Syndicate Department; and Morgan Stanley & Co. LLC, 1585 Broadway, New York, New York 10036, Attention: Equity Syndicate Desk, with a copy to Legal Department; provided, however, that any notice to an Underwriter pursuant to Section 12(e) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters' Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company by you upon request; provided, however, that notices under Section 8 shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to you as the Representatives at Goldman, Sachs & Co., 200 West Street, New York, New York 10282, Attention: Control Department; Wells Fargo Securities, LLC, 375 Park Avenue, New York, New York 10152, Attention: Equity Syndicate Department; and Morgan Stanley & Co. LLC, 1585 Broadway, New York, New York 10036, Attention: Equity Syndicate Desk, with a copy to Legal Department;

(ii) if to any of the NMF Funds, the Adviser or the Administrator shall be delivered or sent by mail, telex or facsimile transmission to New Mountain Finance Corporation, 787 Seventh Avenue, 48th Floor, New York, New York 10019, Attention: Robert Hamwee, with a copy to Steven B. Boehm c/o Sutherland Asbill & Brennan LLP, 700 Sixth Street, NW, Suite 700, Washington, D.C. 20001; and

(iii) if to the Selling Stockholder, shall be delivered or sent by mail, telex or facsimile transmission to New Mountain Finance AIV Holdings Corporation, 787 Seventh Avenue, 48th Floor, New York, New York 10019, Attention: Robert Hamwee, with a copy to Steven B. Boehm, c/o Sutherland Ashbill & Brennan LLP, 700 Sixth Street, NW, Suite 700, Washington, D.C. 20001.

Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including any of the NMF Funds and the Selling Stockholder, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

17. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, each of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder and, to the extent provided in Sections 12 and 14 hereof, the officers and directors of each of the NMF Funds and each person who controls any of the NMF Funds, the Selling Stockholder or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of

any of the Shares from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

18. Time shall be of the essence of this Agreement. As used herein, the term "business day" shall mean any day when the Commission's office in Washington, D.C. is open for business.

19. Each of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder hereby acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement is an arm's-length commercial transaction between the Company and the Selling Stockholder on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor any of the NMF Funds, the Adviser, the Administrator or the Selling Stockholder with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising any of the NMF Funds or the Selling Stockholder on other matters) or any other obligation to any of the NMF Funds, the Adviser, the Administrator or the Selling Stockholder except the obligations expressly set forth in this Agreement and (iv) each of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder has consulted its own legal and financial advisors to the extent it deemed appropriate. Each of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to any of the NMF Funds, the Adviser, the Administrator or the Selling Stockholder in connection with such transaction or the process leading thereto.

20. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the NMF Funds, the Adviser, the Administrator and the Selling Stockholder on the one hand and the Underwriters on the other, or any of them, with respect to the subject matter hereof.

21. THIS AGREEMENT AND ANY MATTERS RELATED TO THIS TRANSACTION SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF NEW YORK.

22. Each of the NMF Funds, the Adviser, the Administrator, the Selling Stockholder and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

23. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

24. Notwithstanding anything herein to the contrary, each of the NMF Funds and the Selling Stockholder is authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to any of the NMF Funds and the Selling Stockholder relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, "tax structure" is limited to any facts that may be relevant to that treatment.

25. Except as set forth below, no claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement (a "Claim") may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and each of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder each consents to the jurisdiction of such courts and personal service with respect thereto. Each of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder each hereby consents to personal jurisdiction, service and venue in any court in which any Claim arising out of or in any way relating to this Agreement is brought by any third party against any Underwriter or any indemnified party. Each Underwriter and each of the NMF Funds (each on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates), the Adviser, the Administrator and the Selling Stockholder (each on its behalf and, to the extent permitted by applicable law, on behalf of its members and affiliates) each waive all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. Each of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder each agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon each of the NMF Funds, the Adviser, the Administrator and the Selling Stockholder and may be enforced in any other courts to the jurisdiction of which any of the NMF Funds, the Adviser, the Administrator or the Selling Stockholder each is or may be subject, by suit upon such judgment.
