Ladies and Gentlemen:

Nuveen Municipal High Income Opportunity Fund 2, a Massachusetts business trust (the “Fund”) and its investment adviser, Nuveen Asset Management, a Delaware corporation (the “Investment Adviser” or “Nuveen”), confirm their agreement with ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Co., ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated (“▇▇▇▇▇▇▇ ▇▇▇▇▇”), and each of the other Underwriters named in Schedule A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom ▇▇▇▇▇▇▇ ▇▇▇▇▇, and [other co-managers] are acting as representatives (in such capacity, the “Representatives”), with respect to the issue and sale by the Fund and the purchase by the Underwriters, acting severally and not jointly, of the respective number of common shares of beneficial interest, par value $0.01 per share, of the Fund (“Common Shares”) set forth in said Schedule A, and with respect to the grant by the Fund to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of [•] additional Common Shares for the sole purpose of covering overallotments, if any. The aforesaid [•]Common Shares (the “Initial Securities”) to be purchased by the Underwriters and all or any part of the [•] Common Shares subject to the option described in Section 2(b) hereof (the “Option Securities”) are hereinafter called, collectively, the “Securities.”

The Fund understands that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Fund has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form N-2 (No. 333-146117 and No. 811-22123) covering the registration of the Securities under the Securities Act of 1933, as amended (the “1933 Act”), including the related preliminary prospectus or prospectuses, and a notification on Form N-8A of registration of the Fund as an investment company under the Investment Company Act of 1940, as amended (the “1940 Act”), and the rules and regulations of the Commission under the 1933 Act and the 1940 Act (the “Rules and Regulations”). Promptly after execution and delivery of this Agreement, the Fund will prepare and file a prospectus in accordance with the provisions of Rule 430A (“Rule 430A”) of the Rules and Regulations and paragraph (c) or (h) of Rule 497 (“Rule 497”) of the Rules and Regulations. The information included in any such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective pursuant to paragraph (b) of Rule 430A is referred to as “Rule 430A Information.” Each prospectus used before such registration statement became effective, and any prospectus that omitted the Rule 430A Information that was used after such effectiveness and prior to the execution and delivery of this Agreement, including in each case any statement of additional information incorporated therein by reference, is herein called a “preliminary prospectus.” Such registration statement, including the exhibits thereto and schedules thereto at the time it became effective and including the Rule 430A Information is herein called the “Registration Statement.” Any registration statement filed pursuant to Rule 462(b) of the Rules and Regulations is herein referred to as the “Rule 462(b) Registration Statement,” and after such filing the term “Registration Statement” shall include the Rule 462(b) Registration Statement. The final prospectus in the form first filed under paragraph (c) or (h) of Rule 497 and furnished to the Underwriters for use in connection with the offering of the Securities, including the statement of additional information incorporated therein by reference, is herein called the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus or the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“▇▇▇▇▇”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, any preliminary prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in the Registration Statement, any preliminary prospectus or the Prospectus, as the case may be.

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Fund and the Investment Adviser. The Fund and the Investment Adviser jointly and severally represent and warrant to each Underwriter as of the date hereof, as of the Applicable Time referred to in Section 1(a)(i) hereof, as of the Closing Time referred to in Section 2(c) hereof, and as of each Date of Delivery (if any) referred to in Section 2(b) hereof, and agree with each Underwriter, as follows:

instituted or are pending or, to the knowledge of the Fund or the Investment Adviser, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with.

At the respective times the Registration Statement, any Rule 462(b) Registration Statement and any post-effective amendments thereto became effective and at the Closing Time (and, if any Option Securities are purchased, at the Date of Delivery), the Registration Statement, the Rule 462(b) Registration Statement, the notification on Form N-8A and any amendments and supplements thereto complied and will comply in all material respects with the requirements of the 1933 Act, the 1940 Act and the Rules and Regulations and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. Neither the Prospectus nor any amendments or supplements thereto, on the respective date of the Prospectus or any such amendment or supplement and at the Closing Time (and, if any Option Securities are purchased, at the Date of Delivery), included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Each preliminary prospectus and the prospectus filed as part of the effective Registration Statement or as part of any amendment thereto, or filed pursuant to Rule 497 under the 1933 Act, complied when so filed in all material respects with the Rules and Regulations and each preliminary prospectus and the Prospectus delivered to the Underwriters for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

Fund of its obligations hereunder).

All sales material complied and will comply in all material respects with the applicable requirements of the 1933 Act, the 1940 Act and the Rules and Regulations and the rules and interpretations of the NASD.

Assuming due authorization, execution and delivery by the other parties thereto, each such Agreement constitutes a valid and binding agreement of the Fund, enforceable in accordance with its terms, except as affected by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws, whether statutory or decisional, relating to or affecting creditors’ rights generally, general equitable principles (whether considered in a proceeding in equity or at law) and an implied covenant of good faith and fair dealing and except as rights to indemnification or contribution thereunder may be limited by federal or state laws.

(a) Initial Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Fund agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Fund, at the price per share set forth in Schedule B, the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter, plus any additional number of Initial Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof.

If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter bears to the total number of Initial Securities, subject in each case to such adjustments as ▇▇▇▇▇▇▇ ▇▇▇▇▇ in its discretion shall make to eliminate any sales or purchases of a fractional number of Option Securities plus any additional number of Option Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof.

(Eastern time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by the Representatives and the Fund (such time and date of payment and delivery being herein called “Closing Time”).

In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, payment of the purchase price for, and delivery of certificates, if any, for, such Option Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Representatives and the Fund, on each Date of Delivery as specified in the notice from the Representatives to the Fund.

Payment shall be made to the Fund by wire transfer of immediately available funds to a bank account designated by the Fund, against delivery to the Representatives for the respective accounts of the Underwriters of certificates, if any, for the Securities to be purchased by them. It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase. ▇▇▇▇▇▇▇ ▇▇▇▇▇, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

(d) Denominations; Registration. Certificates for the Initial Securities and the Option Securities, if any, shall be in such denominations and registered in such names as the Representatives may request in writing at least one full business day before the Closing Time or the relevant Date of Delivery, as the case may be. The certificates, if any, for the Initial Securities and the Option Securities, if any, will be made available for examination and packaging by the Representatives in the City of New York not later than 10:00 A.M. (Eastern time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be.

SECTION 3. Covenants.

The Fund and the Investment Adviser, jointly and severally, covenant with each Underwriter as follows:

(a) Compliance with Securities Regulations and Commission Requests. The Fund, subject to Section 3(b), will comply with the requirements of Rule 430A and will notify the Representatives immediately, and confirm the notice in writing, (i) when any post-effective amendment to the Registration

Statement shall become effective, or any supplement to the Prospectus or any amended Prospectus shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or any document incorporated by reference therein or for additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes or of any examination pursuant to Section 8(e) of the 1933 Act concerning the Registration Statement and (v) if the Fund becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Securities. The Fund will promptly effect the filings necessary pursuant to Rule 497 and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 497 was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Fund will make every reasonable effort to prevent the issuance of any stop order, or order of suspension or revocation of registration pursuant to Section 8(e) of the 1940 Act, and, if any such stop order or order of suspension or revocation of registration is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments. The Fund will give the Representatives notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b)) or any amendment, supplement or revision to either the prospectus included in the Registration Statement at the time it became effective or to the Prospectus, and will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object.

(c) Delivery of Registration Statements. The Fund has furnished or will deliver to the Representatives and counsel to the Underwriters, without charge, a signed copy of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein) and a signed copy of all consents and certificates of experts, and will also deliver to the Representatives, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits) for each of the Underwriters. The copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(d) Delivery of Prospectuses. The Fund has delivered to each Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter reasonably requested, and the Fund hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Fund will furnish to each Underwriter, without charge, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such number of copies of the Prospectus (as amended or supplemented) as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(e) Continued Compliance with Securities Laws. If at any time when the Prospectus (as amended or supplemented) is required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Fund, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall

be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the Rules and Regulations, the Fund will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Fund will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request. If at any time following issuance of a Rule 482 Statement, there occurred or occurs an event or development as a result of which such Rule 482 Statement included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in light of the circumstances, prevailing at that subsequent time, not misleading, the Fund will promptly notify ▇▇▇▇▇▇▇ ▇▇▇▇▇ and will promptly amend or supplement, at its own expense, such Rule 482 Statement to eliminate or correct such conflict.

(f) Blue Sky Qualifications. The Fund will use its best efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions of the United States as the Representatives may designate and to maintain such qualifications in effect for a period of not less than one year from the later of the effective date of the Registration Statement and any Rule 462(b) Registration Statement; provided, however, that the Fund shall not be obligated to file any general consent to service of process or to qualify as a foreign entity or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Securities have been so qualified, the Fund will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for a period of not less than one year from the effective date of the Registration Statement and any Rule 462(b) Registration Statement.

(g) Rule 158. The Fund will make generally available to its securityholders as soon as practicable an earnings statement, if applicable, for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(h) Use of Proceeds. The Fund will use the net proceeds received by it from the sale of the Securities substantially in the manner specified in the Prospectus under “Use of Proceeds.”

(i) Listing. The Fund will use its reasonable best efforts to cause the Securities to be duly authorized for listing by the NYSE, prior to the date the Securities are issued.

(j) Restriction on Sale of Securities. During a period of 180 days from the date of the Prospectus, the Fund will not, without the prior written consent of ▇▇▇▇▇▇▇ ▇▇▇▇▇, (A) directly or indirectly, offer, pledge, sell, contract to sell, sell any option, rights or warrant to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of Common Shares or any securities convertible into or exercisable or exchangeable for Common Shares or file any registration statement under the 1933 Act with respect to any of the foregoing or (B) 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 Shares, whether any such swap or transaction described in clause (A) or (B) above is to be settled by delivery of Common Shares or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (1) the Securities to be sold hereunder or (2) Common Shares issued or, for avoidance of doubt, purchased in the open market pursuant to any dividend reinvestment plan.

(k) Reporting Requirements. The Fund, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, will file all documents required to be filed with the Commission pursuant to the 1940 Act and the 1934 Act within the time periods required by the 1940 Act and the Rules and Regulations and the 1934 Act and the rules and regulations of the Commission thereunder, respectively.

(l) Subchapter M. The Fund will use its best efforts to comply with the requirements of Subchapter M of the Code to qualify as a regulated investment company under the Code.

(m) No Manipulation of Market for Securities. The Fund will not (a) take, directly or indirectly, any action designed to cause or to result in, or that might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Fund to facilitate the sale or resale of the Securities in violation of federal or state securities laws, and (b) except for share repurchases permitted in accordance with applicable laws and purchases of Securities in the open market pursuant to the Fund’s dividend reinvestment plan, until the Closing Date, or the Date of Delivery, if any, (i) sell, bid for or purchase the Securities or pay any person any compensation for soliciting purchases of the Securities or (ii) pay or agree to pay to any person any compensation for soliciting another to purchase any other securities of the Fund.

(n) Rule 462(b) Registration Statement. If the Fund elects to rely upon Rule 462(b), the Fund shall file a Rule 462(b) Registration Statement with the Commission in compliance with Rule 462(b) by 10:00 P.M., Washington, D.C. time, on the date of this Agreement, and the Fund shall at the time of filing either pay to the Commission the filing fee for the Rule 462(b) Registration Statement or give irrevocable instructions for the payment of such fee pursuant to Rule 111(b) under the 1933 Act.

SECTION 6. Indemnification.

(a) Indemnification of Underwriters. The Fund and the Investment Adviser, jointly and severally, agree to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430A Information, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, any Rule 482 Statement or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(e) below) any such settlement is effected with the written consent of the Fund; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by ▇▇▇▇▇▇▇ ▇▇▇▇▇), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Fund or the Investment Adviser by any Underwriter through ▇▇▇▇▇▇▇ ▇▇▇▇▇ expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information, or any preliminary prospectus, any Rule 482 Statement or the Prospectus (or any amendment or supplement thereto); provided, further, that the indemnity agreement contained in this Section 6 shall not inure to the benefit of any Underwriter from whom the person asserting any loss, claim, damage or liability purchased the Securities, if it is shown that a copy of the Prospectus, as then amended or supplemented, which would have cured any defect giving arise to such loss, claim, damage or liability was not sent or delivered to such person by or on behalf of such Underwriter, if required by law to be so delivered to, at or prior to the confirmation of the sale of such Securities to such person and such Prospectus, amendments and supplements have been provided by the Fund to the Underwriters in the requisite quantity and on a timely basis to permit proper delivery.

(b) Indemnification of the Fund, the Investment Adviser, Trustees, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Fund and the Investment Adviser, their respective trustees, directors and shareholders, each of the Fund’s officers who signed the Registration Statement, and each person, if any, who controls the Fund or the Investment Adviser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information, or any preliminary prospectus, any Rule 482 Statement or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Fund or the Investment Adviser by such Underwriter through ▇▇▇▇▇▇▇ ▇▇▇▇▇ expressly for use therein.

(c) Indemnification for Marketing Materials. In addition to the foregoing indemnification, the Fund and the Investment Adviser also, jointly and severally, agree to indemnify and hold harmless

each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 6(a), as limited by the proviso set forth therein, with respect to any sales material.

(d) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by ▇▇▇▇▇▇▇ ▇▇▇▇▇, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Fund and the Investment Adviser. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(e) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) (through, if applicable, the provisions of Section 6(b)) effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution.

If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then, in lieu of indemnifying such indemnified party, each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Fund or the Investment Adviser on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 Fund and the Investment Adviser on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Fund and the Investment Adviser on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Fund and the total underwriting discount received by the Underwriters (whether from the Fund or otherwise), in each case as set forth on the cover of the Prospectus.

The relative fault of the Fund and the Investment Adviser on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Fund or the Investment Adviser or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Fund, the Investment Adviser and the Underwriters 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 above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities 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 any 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 ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each trustee and shareholder of the Fund and each director of the Investment Adviser, respectively, each officer of the Fund who signed the Registration Statement, and each person, if any, who controls the Fund or the Investment Adviser, within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Fund and the Investment Adviser, respectively. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery.

All representations, warranties and covenants contained in this Agreement or in certificates of officers of the Fund or the Investment Adviser submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Fund or the Investment Adviser, and shall survive delivery of the Securities to the Underwriters.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Fund, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus or the General Disclosure Package, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Fund or the Investment Adviser, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in the Common Shares of the Fund has been suspended or materially limited by the Commission or the NYSE, or if trading generally on the American Stock Exchange or the NYSE or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the NASD or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (iv) if a banking moratorium has been declared by either Federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the Underwriters.

If one or more of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase and of the Fund to sell the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Fund to sell the relevant Option Securities, as the case may be, either the Representatives or the Fund shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any

required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

SECTION 11. Notices.

All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to the Representatives, c/o Merrill ▇▇▇▇▇ & Co., ▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, attention of Equity Capital Markets; and notices to the Fund or Nuveen shall be directed to Nuveen Asset Management, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇ ▇. Berkshire.

SECTION 12. Parties.

This Agreement shall each inure to the benefit of and be binding upon the Underwriters, the Fund, the Investment Adviser and their respective partners and successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Fund, the Investment Adviser and their respective successors and the controlling persons and officers, trustees, shareholders and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Fund, the Investment Adviser and their respective partners and successors, and said controlling persons and officers, trustees, shareholders and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 13. NO ADVISORY OR FIDUCIARY RELATIONSHIP.

The Fund acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Fund, on the one hand, and the several Underwriters, on the other hand, (ii) in connection with the offering contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Fund or its shareholders, creditors, employees or any other party, (iii) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Fund with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Fund on other matters) and no Underwriter has any obligation to the Fund with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (iv) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Fund, and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Fund has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 14. GOVERNING LAW AND TIME.

THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SAID STATE. UNLESS OTHERWISE EXPLICITLY PROVIDED, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 15. Disclaimer of Liability of Trustees and Beneficiaries.

A copy of the Agreement and Declaration of Trust of the Fund is on file with the Secretary of State of The Commonwealth of Massachusetts, and notice hereby is given that this Agreement is executed on behalf of the Fund by an officer or trustee of the Fund in his or her capacity as an officer or trustee of the Fund and not individually and that the obligations under or arising out of this Agreement are not binding upon any of the trustees, officers or shareholders individually but are binding only upon the assets and properties of the Fund.

The Article and Section headings herein are for convenience only and shall not affect the construction hereof.
