If such fee is an "other distribution" pursuant to the Articles Supplementary, such fee shall be paid pursuant to and in accordance with the Articles Supplementary, including Section 2.2(c) of the Articles Supplementary. Notwithstanding the foregoing, in no event shall (i) the fee payable pursuant to this Section 2.4 hereunder for any Week plus the Applicable Spread on the 2018 VMTP Shares for such Week exceed an amount (exclusive of any Additional Amount Payment) equal to the product of (x) 15%, times (y) the aggregate average daily Liquidation Preference of the 2018 VMTP Shares held by such Purchaser during such Week or portion thereof, times (z) the quotient of the number of days in such Week or portion thereof divided by the number of calendar days in the year in which such Week or portion thereof occurs; (ii) the fee payable pursuant to this Section 2.4 for any Week plus the amount of dividends payable at the Dividend Rate for the 2018 VMTP Shares for such Week exceed an amount equal to the product of (aa) 15%, times (bb) the aggregate average daily Liquidation Preference of the 2018 VMTP Shares held by such Purchaser during such Week or portion thereof, times (cc) the quotient of the number of days in such Week or portion thereof divided by the number of calendar days in the year in which such Week or portion thereof occurs; or (iii) the Issuer be required to calculate or pay a fee in respect of more than one Failure in any Week.

7.2	No Waivers

(a)

The obligations of the Issuer hereunder shall not in any way be modified or limited by reference to any other document, instrument or agreement (including, without limitation, the 2018 VMTP Shares or any other Related Document). The rights of each Purchaser hereunder are separate from and in addition to any rights that any Holder or Designated Owner of any 2018 VMTP Share may have under the terms of such 2018 VMTP Share or any Related Document or otherwise.

(b)

No failure or delay by the Issuer or either Purchaser in exercising any right, power or privilege hereunder or under the 2018 VMTP Shares shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. No failure or delay by the Issuer or either Purchaser in exercising any right, power or privilege under or in respect of the 2018 VMTP Shares or any other Related Document shall affect the rights, powers or privileges of the Issuer or either Purchaser hereunder or shall operate as a limitation or waiver thereof. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

7.3	Expenses and Indemnification

(a)

The Issuer shall upon demand either, as each Purchaser may require, pay in the first instance or reimburse such Purchaser (to the extent that payments for the following items are not made under the other provisions hereof) for all reasonable out-of-pocket expenses (including reasonable fees and costs of outside counsel, and reasonable consulting, accounting, appraisal, investment banking, and similar professional fees and charges) incurred by such Purchaser in connection with the enforcement of or preservation of rights under this Agreement. The Issuer shall not be responsible under this Section 7.3(a) for the fees and costs of more than one law firm in any one jurisdiction with respect to any one proceeding or set of related proceedings for such Purchaser, unless such Purchaser shall have reasonably concluded that there are legal defenses available to it that are different from or additional to those available to the Issuer.

(b)

The Issuer agrees to indemnify and hold harmless each Purchaser and each other Indemnified Person of such Purchaser from and against any losses, claims, damages, liabilities and reasonable out-of-pocket expenses incurred by them (including reasonable fees and disbursements of outside counsel) that are related to or arise out of (i) any material misstatements or any material statements omitted to be made in the Information Statement (including any documents incorporated by reference therein) or (ii) any claim by any third party relating to the offering or sale of the 2018 VMTP Shares by the Issuer or the holding of the 2018 VMTP Shares by such Purchaser (A) that such Purchaser aided and abetted a breach of a fiduciary duty by the Issuer or any director or officer of the Issuer or (B) arising from any act by the Issuer or any director or officer of the Issuer (excluding in any such case clauses (i) or (ii), claims, losses, liabilities or expenses arising out of or resulting from the gross negligence or willful misconduct of any Indemnified Person as determined by a court of competent jurisdiction, and any consequential, special or punitive damages or losses consisting of trading losses, speculative losses, loss of profit or loss of business opportunity).

(c)

The indemnifying party also agrees that if any indemnification sought by an Indemnified Person pursuant to this Agreement is unavailable or insufficient, for any reason, to hold harmless the Indemnified Persons of such other party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), then the indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, liabilities, damages and expenses (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the Issuer on the one hand and the Purchasers on the other hand from the actual or proposed transactions giving rise to or contemplated by this Agreement or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the Issuer on the one hand and the Purchasers on the other, in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages, liabilities or expenses (or actions in respect thereof), as well as any other relevant equitable considerations; provided that in any event the aggregate contribution of each Purchaser and their Indemnified Persons to all losses, claims, damages, liabilities and expenses with respect to which contributions are available hereunder will not exceed the amount of dividends actually received by such Purchaser from the Issuer pursuant to the proposed transactions giving rise to this Agreement. For purposes of determining the relative benefits to the Issuer on the one hand, and the Purchasers on the other, under the proposed transactions giving rise to or contemplated by this Agreement, such benefits shall be deemed to be in the same proportion as (i) the total value received or proposed to be received by the Issuer pursuant to the transactions, whether or not consummated bears to (ii) the dividends and Optional Redemption Premium paid by the Issuer to such Purchaser in connection with the proposed transactions giving rise to or contemplated by this Agreement. The relative fault of the parties shall be determined by reference to, among other things, whether the actions taken or omitted to be taken in connection with the proposed transactions contemplated by this Agreement (including any misstatement of a material fact or the omission to state a material fact) relates to information supplied by the Issuer on the one hand, or the Purchasers on the other, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action, misstatement or alleged omission, and any other equitable considerations appropriate in the circumstances. No person found liable for a fraudulent misrepresentation shall be entitled to contribution from any person who is not also found liable for such fraudulent misrepresentation. The indemnity, reimbursement and contribution obligations under this Agreement shall be in addition to any rights that any Indemnified Person may have at common law or otherwise.

(d)

If any action, suit, proceeding or investigation is commenced, as to which an Indemnified Person proposes to demand indemnification, it shall notify the indemnifying party with reasonable promptness; provided, however, that any failure by such Indemnified Person to notify the indemnifying party shall not relieve the indemnifying party from its obligations hereunder (except to the extent that the indemnifying party is materially prejudiced by such failure to promptly notify). The indemnifying party shall be entitled to assume the defense of any such action, suit, proceeding or investigation, including the employment of counsel reasonably satisfactory to the Indemnified Person. The Indemnified Person shall have the right to counsel of its own choice to represent it, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the indemnifying party has failed promptly to assume the defense and employ counsel reasonably satisfactory to the Indemnified Person in accordance with the preceding sentence or (ii) the Indemnified Person shall have been advised by counsel that there exist actual or potential conflicting interests between the indemnifying party and such Indemnified Person, including situations in which one or more legal defenses may be available to such Indemnified Person that are different from or additional to those available to the indemnifying party; provided, however, that the indemnifying party shall not, in connection with any one such action or proceeding or separate but substantially similar actions or proceedings arising out of the same general allegations be liable for fees and expenses of more than one separate firm of attorneys at any time for all Indemnified Persons of such other party; and such counsel shall, to the extent consistent with its professional responsibilities, cooperate with the indemnifying party and any counsel designated by the indemnifying party.

Each party further agrees that it will not, without the prior written consent of the other parties (the consent of a party shall not be required to the extent such party is neither requesting indemnification nor being requested to provide indemnification), settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not any Indemnified Person is an actual or potential party to such claim, action, suit or proceeding) unless such settlement, compromise or consent includes an unconditional release of each other Indemnified Person from all liability and obligations arising therefrom. The Issuer further agrees that neither of the Purchasers, nor any of their affiliates, nor any directors, officers, partners, employees, agents, representatives or control persons of either Purchaser or any of its affiliates shall have any liability to the Issuer arising out of or in connection with the proposed transactions giving rise to or contemplated by this Agreement except for such liability for losses, claims, damages, liabilities or expenses to the extent they have resulted from the Purchasers' or their affiliates' gross negligence or willful misconduct. No Indemnified Person shall be responsible or liable to the indemnifying party or any other person for consequential, special or punitive damages which may be alleged as a result of this Agreement.

(e)	Nothing in this Section 7.3 is intended to limit any party's obligations contained in other parts of this Agreement or the 2018 VMTP Shares.

7.4	Amendments and Waivers

Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Issuer and the Purchasers; provided, that the Issuer shall not make or agree to any amendment or waiver to the Charter or the Articles Supplementary that affects any preference, right or power of the 2018 VMTP Shares or the Holders or Designated Owners thereof except as permitted under the Charter or the Articles Supplementary.

7.5	Successors and Assigns

The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Neither the Issuer nor either Purchaser may assign or otherwise transfer any of its rights or obligations under this Agreement without the prior written consent of the other party (other than by operation of law), except that (i) any transferee satisfying the requirements set forth in Section 2.1 and which has executed and delivered to the Issuer the transferee certificate attached as Exhibit C shall, prior to registration of any 2018 VMTP Shares under the Securities Act, have the rights set forth in Section 6.17 and Section 7.15 and shall, so long as such transferee has provided a means for the Issuer to transmit such information electronically to it, be entitled to receive the information delivered pursuant to Sections 6.1(o) and 6.1(p) and such transferees shall be deemed a party to this Agreement for purposes of Sections 6.1(o), 6.1(p) and the confidentiality provisions herein as specified in the transferee certificate and (ii) each Purchaser may assign its rights or obligations to any affiliate of such Purchaser or any tender option bond trust (or other similar investment vehicles) in which such Purchaser or an affiliate of such Purchaser retains the entire residual interest. Any assignment without such prior written consent shall be void.

7.6	Term of this Agreement

This Agreement shall terminate on the earlier of (i) the registration of any Outstanding 2018 VMTP Shares under the Securities Act and (ii) payment in full of all amounts then due and owing to either Purchaser hereunder and under the 2018 VMTP Shares; and notwithstanding any termination of this Agreement, Section 7.3, Section 7.7, Section 7.8, Section 7.10, Section 7.11, the second sentence of Section 7.12, and Section 7.13 (for a period of two years after the termination of this Agreement) shall remain in full force and effect.

7.8	Waiver of Jury Trial

The Issuer and each Purchaser hereby waive trial by jury in any action, proceeding or counterclaim brought by either of the parties hereto against any other on any matters whatsoever arising out of or in any way connected with this Agreement.

7.9	Counterparts

This Agreement may be signed in counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Any counterpart or other signature delivered by facsimile or by electronic mail shall be deemed for all purposes as being a good and valid execution and delivery of this Agreement by that party.

7.10	Beneficiaries

This Agreement is not intended and shall not be construed to confer upon any Person other than the parties hereto and their successors and permitted assigns any rights or remedies hereunder.

7.11	Entire Agreement

Except as set forth in Section 7.5, this Agreement shall constitute the entire agreement and understanding between the parties hereto with respect to the matters set forth herein and shall supersede any and all prior agreements and understandings relating to the subject matter hereof.

7.12	Relationship to the Articles Supplementary

The Issuer and each Purchaser agree that the representations, warranties, covenants and agreements contained in this Agreement are in addition to the terms and provisions set forth in the Articles Supplementary. As between the Issuer and each Purchaser, the Issuer and each Purchaser agree that Section 2.10(d) of the Articles Supplementary shall have no effect for so long as none of the 2018 VMTP Shares have been registered under the Securities Act.

7.13	Confidentiality

Any information delivered by a party to this Agreement to any other party pursuant to this Agreement, including, without limitation, pursuant to Section 6.1 in the case of the Issuer (collectively, the "Information"), shall not be disclosed by such other party (or its employees, representatives or agents) to any person or entity (except as required by law or to such of its agents and advisors as need to know and agree to be bound by the provisions of this paragraph) or used by such other party for any purpose other than as contemplated by this Agreement without the prior written consent of the party delivering the Information.

The obligations of confidentiality set out in the preceding paragraph do not extend to Information that is or becomes available to the public or is or becomes available to the party receiving the Information on a non-confidential basis or is disclosed to Holders or Designated Owners or potential Holders or Designated Owners, in each case in their capacity as such, in the offering documents of the Issuer, in notices to Holders or Designated Owners pursuant to one or more of the Related Documents or pursuant to the Issuer's or each Purchaser's informational obligations under Rule 144A(d)(4) or other reporting obligation of the Securities and Exchange Commission; or is required or requested to be disclosed (i) by a regulatory agency or in connection with an examination of either party or its representatives by regulatory authorities, (ii) pursuant to subpoena or other court process, (iii) at the express direction of any other authorized government agency, (iv) to its independent attorneys or auditors, (v) as required by any NRSRO, (vi) as otherwise required by law or regulation, (vii) otherwise in connection with the enforcement of this Agreement, (viii) in connection with the exercise of any remedies hereunder or in any suit, action or proceeding relating to this Agreement and the enforcement of rights hereunder, (ix) by a prospective purchaser of the 2018 VMTP Shares that is (a) a transferee that would be permitted pursuant to Section 2.1(b) of this Agreement and (b) aware of the confidentiality provisions of this Section 7.13 and is subject to an agreement with the transferor containing provisions substantially similar thereto and that states that the Issuer is an express third party beneficiary thereof, (x) subject to an agreement containing provisions substantially similar to those of this Section 7.13, or (xi) subject to an agreement containing provisions substantially similar to those of this Section 7.13 and with the prior written consent of the other party to this Agreement, which consent shall not be unreasonably withheld, to any actual or prospective counterparty in any swap or derivative transactions. For the avoidance of doubt, references in this Section 7.13 to "regulatory agency," "regulatory authorities," "government agency" and "law or regulation" shall be deemed to include the Internal Revenue Service and state taxation authorities.

7.14	Severability

In case any provision of this Agreement shall be invalid, illegal, or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby so long as the intent of the Parties to this Agreement shall be preserved.

7.15	Consent Rights of the Majority Participants to Certain Actions.

For so long as none of the 2018 VMTP Shares have been registered under the Securities Act, without the affirmative vote or consent of the Majority Participants, neither the Issuer nor the Board of Directors will take or authorize the taking of any of the actions set forth under clauses (a) through (e) of this Section 7.15:

(a)	The termination by the Issuer of any Rating Agency or the selection of any Other Rating Agency, either in replacement for a Rating Agency or as an additional Rating Agency with respect to the 2018 VMTP Shares.

(b)

The Issuer issuing or suffering to exist any "senior security" (as defined in the 1940 Act as of the date hereof, but not including a Derivative Contract, or, in the event such definition shall be amended, with such changes to the definition thereof as consented to by the Majority Participants) other than the 2018 VMTP Shares issued and sold pursuant to this Agreement or indebtedness for borrowed money of the Issuer, except (i) borrowings for temporary purposes in an amount not to exceed 5% of the assets of the Issuer, which borrowings are repaid within 60 days, (ii) the issuance of senior securities or the incurrence of indebtedness for borrowed money, the proceeds of which will be used for the redemption or repurchase of the 2018 VMTP Shares and costs incurred in connection therewith, (iii) the Issuer's previously issued and outstanding APS and Original VMTP Shares, and (iv) as may be otherwise approved or consented to by the Majority Participants, provided that if any such "senior security" is created or incurred by the Issuer it shall not require the approval of the Majority Participants if the Issuer redeems, retires or terminates such "senior security" or otherwise cures such non-compliance within five Business Days of receiving notice of the existence thereof.

(c)

The Issuer (i) creating or incurring or suffering to be incurred or to exist any lien on any other funds, accounts or other property held under the Charter or the Articles Supplementary, except as permitted by the Charter or the Articles Supplementary or (ii) except for any lien for the benefit of the Custodian of the Issuer on the assets of the Issuer held by such Custodian, pledging any portfolio security to secure any senior securities or other liabilities to be incurred by the Issuer (including under any tender option bond trust of which the residual floating rate trust certificates will be owned by the Issuer) unless the securities pledged pursuant to all such pledges or other security arrangements are valued for purposes of such security arrangements in an aggregate amount not less than 70% of their aggregate market value (determined by an independent third party pricing service) for purposes of determining the value of the collateral required to be posted or otherwise provided under all such security arrangements; provided, that the required collateral value under such security arrangements shall not exceed the market value of the exposure of each secured party to the credit of the Issuer; and provided further, that it shall not require the approval of the Majority Participants if any pledge or security interest in violation of the preceding sentence is created or incurred by the Issuer and the Issuer cures such violation within five Business Days of receiving notice of the existence thereof.

(d)

Approval of any amendment, alteration or repeal of any provision of the Charter or the Articles Supplementary, whether by merger, consolidation or otherwise, that would affect any preference, right or power of the 2018 VMTP Shares differentially from the rights of the holders of the Common Shares; or

(e)

Approval of any action to be taken pursuant to Sections 2.5(g) of the Articles Supplementary (other than the issuance of additional series of Variable Rate MuniFund Term Preferred Shares or other Preferred Shares, the proceeds of which will be used for the redemption or repurchase of the 2018 VMTP Shares and costs incurred in connection therewith).

In addition, if the Board of Directors shall designate a replacement to the S&P Weekly High Grade Municipal Index pursuant to the definition of SIFMA Municipal Swap Index contained in the Articles Supplementary, the Issuer shall notify the Holders of the 2018 VMTP Shares within five Business Days of such designation, and if within 30 days of such notice the Majority Participants shall have objected in writing to the designated replacement, the Board of Directors shall designate a replacement to such index as agreed to between the Issuer and the Majority Participants. In such event, the replacement index initially approved by the Board of Directors shall be the index in effect for purposes of the Articles Supplementary until a new index has been approved by the Issuer and the Majority Participants.

ELIGIBLE ASSETS

On the Effective Date and at all times thereafter:

1. All assets in the Issuer consist of "Eligible Assets", defined to consist only of the following as of the time of investment:

A. Debt obligations

"Municipal securities", defined as obligations of a State, the District of Columbia, a U.S. territory, or a political subdivision thereof and including general obligations, limited obligation bonds, revenue bonds, and obligations that satisfy the requirements of section 142(b)(1) of the Internal Revenue Code of 1986 issued by or on behalf of any State, the District of Columbia, any U.S. territory or any political subdivision thereof, including any municipal corporate instrumentality of 1 or more States, or any public agency or authority of any State, the District of Columbia, any U.S. territory or any political subdivision thereof. The purchase of any municipal security will be based upon the Investment Adviser's assessment of an asset's relative value in terms of current yield, price, credit quality, and future prospects; and the Investment Adviser will monitor the creditworthiness of the Issuer's portfolio investments and analyze economic, political and demographic trends affecting the markets for such assets. Eligible Assets shall include any municipal securities that at the time of purchase are paying scheduled principal and interest or if at the time of purchase are in payment default, then in the sole judgment of the Investment Adviser are expected to produce payments of principal and interest whose present value exceeds the purchase price.

ii.	Debt obligations of the United States.

iii.	Debt obligations issued, insured, or guaranteed by a department or an agency of the U.S. Government, if the obligation, insurance, or guarantee commits the full faith and credit of the United States for the repayment of the obligation.

iv.	Debt obligations of the Washington Metropolitan Area Transit Authority guaranteed by the Secretary of Transportation under Section 9 of the National Capital Transportation Act of 1969.

v.	Debt obligations of the Federal Home Loan Banks.

vi.	Debt obligations, participations or other instruments of or issued by the Federal National Mortgage Association or the Government National Mortgage Association.

vii.	Debt obligations which are or ever have been sold by the Federal Home Loan Mortgage Corporation pursuant to sections 305 or 306 of the Federal Home Loan Mortgage Corporation Act.

viii.

Debt obligations of any agency named in 12 U.S.C. § 24(Seventh) as eligible to issue obligations that a national bank may underwrite, deal in, purchase and sell for the bank's own account, including qualified Canadian government obligations.

ix.	Debt obligations of issuers other than those specified in (i) through (viii) above that are "investment grade" and that are "marketable." For these purposes, an obligation is:

(aa) "marketable" if:

●	it is registered under the Securities Act;

●	it is offered and sold pursuant to Securities and Exchange Commission Rule 144A; 17 CFR 230.144A; or

●	it can be sold with reasonable promptness at a price that corresponds reasonably to its fair value; and

(bb) "investment grade" if:

●	the obligor had adequate capacity to meet financial commitments under the security for the projected life of the asset or exposure, which capacity is presumed if the risk of default by the obligor is low and the full and timely repayment of principal and interest is expected.

Certificates or other securities evidencing ownership interests in a municipal bond trust structure (generally referred to as a tender option bond structure) that invests in (a) debt obligations of the types described in (i) above or (b) depository receipts reflecting ownership interests in accounts holding debt obligations of the types described in (i) above.

xi.	The bonds, notes and other debt securities referenced in (A) above shall be defined as Eligible Assets. An asset shall not lose its status as an Eligible Asset solely by virtue of the fact that:

●	it provides for repayment of principal and interest in any form including fixed and floating rate, zero interest, capital appreciation, discount, leases, and payment in kind; or

●	it is for long-term or short-term financing purposes.

B. Derivatives

i.	Interest rate derivatives;

ii.	Swaps, futures, forwards, structured notes, options and swaptions related to Eligible Assets or on an index related to Eligible Assets; or

iii.	Credit default swaps.

C. Other Assets

Shares of other investment companies (open- or closed-end funds and ETFs) the assets of which consist entirely of Eligible Assets based on the Investment Adviser's assessment of the assets of each such investment company taking into account the investment company's most recent publicly available schedule of investments and publicly disclosed investment policies.

ii.

Cash.

iii.	Repurchase agreements on assets described in A above.

iv.

Taxable fixed-income securities, for the purpose of acquiring control of an issuer whose municipal bonds (a) the Issuer already owns and (b) have deteriorated or are expected shortly to deteriorate that such investment should enable the Issuer to better maximize its existing investment in such issuer, provided that the Issuer may invest no more than 0.5% of its total assets in such securities.

D. Other assets, upon written agreement of all Holders of the 2018 VMTP Shares ("Holders") that such assets are eligible for purchase by the Holder.

2. The Investment Adviser has instituted policies and procedures that it believes are sufficient to ensure that the Issuer and it comply with the representations, warranties and covenants contained in this Exhibit to the Agreement.

3. The Issuer will, upon request, provide each Holder and their internal and external auditors and inspectors as such Holder may from time to time designate, with all reasonable assistance and access to information and records of the Issuer relevant to the Issuer's compliance with and performance of the representations, warranties and covenants contained in this Exhibit to the Agreement, but only for the purposes of internal and external audit.

Capitalized terms used but not defined herein shall have the meanings given them in the Purchase Agreement.

In connection with the proposed sale by the Transferor of _______________ 2018 VMTP Shares (the "Transferred Shares") to the undersigned transferee (the "Transferee"), the undersigned agrees and acknowledges, on its own behalf, and makes the representations and warranties, on its own behalf, as set forth in this certificate (this "Transferee Certificate") to the Fund and the Transferor:

1. The Transferee certifies to one of the following (check a box):

q it is a "qualified institutional buyer" (a "QIB") (as defined in Rule 144A under the Securities Act or any successor provision) ("Rule 144A") that is (a) a registered closed-end management investment company, the shares of which are traded on a national securities exchange, or registered open-end management investment company, in either case, that (X) is either sponsored or managed by an entity listed on Schedule 2 to the Purchase Agreement or any other entity that is controlled by, controlling or under common control with an entity listed on Schedule 2 to the Purchase Agreement and (Y) invests primarily in municipal obligations (each, a "Registered Investment Company"); (b) bank or entity that is a 100% direct or indirect subsidiary of a bank's publicly traded parent holding company (collectively, "Banks"); or (c) an insurance company, in each case, pursuant to Rule 144A or another available exemption from registration under the U.S. Securities Act of 1933, as amended (the "Securities Act"), in a manner not involving any public offering within the meaning of Section 4(a)(2) of the Securities Act;

q it is a tender option bond trust (or other similar investment vehicles) in which all investors are QIBs that are Registered Investment Companies, Banks or insurance companies (or, in the case of a tender option bond trust (or other similar investment vehicles) in which the Holder or an affiliate of the Holder retains a residual interest); or

q is a person which the Fund has consented in writing to permit to be the holder of the Transferred Shares.

2. The Transferee certifies that it (check a box):

q is not an AllianceBernstein Person that after such sale and transfer, would own more than 20% of the Outstanding 2018 VMTP Shares; or

q is an AllianceBernstein Person that after such sale and transfer, would own more than 20% of the Outstanding 2018 VMTP Shares and it has received the prior written consent of each of the Fund and the holder(s) of more than 50% of the outstanding 2018 VMTP Shares to invest in those shares.

3. The Transferee understands and acknowledges that the Transferred Shares are "restricted securities" and have not been registered under the Securities Act or any other applicable securities law, are being offered for sale pursuant to Rule 144A of the Securities Act or another available exemption from registration under the Securities Act, in a manner not involving any public offering with the meaning of Section 4(a)(2) of the Securities Act, and may not be offered, sold or otherwise transferred except in compliance with the registration requirements of the Securities Act or any other applicable securities law, pursuant to an exemption therefrom or in a transaction not subject thereto and in each case in compliance with the conditions for transfer set forth in this Transferee Certificate.

4. The Transferee is purchasing the Transferred Shares for its own account for investment, and not with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act, subject to any requirements of law that the disposition of its property be at all times within its or their control and subject to its or their ability to resell such securities pursuant to Rule 144A or any exemption from registration available under the Securities Act.

5. The Transferee agrees on its own behalf and on behalf of each subsequent holder or owner of the Transferred Shares by its acceptance thereof will agree to sell, transfer or otherwise dispose of the Transferred Shares only in whole shares and only to (1)(i) to Persons that it reasonably believes are QIBs that are (a) registered closed-end management investment companies, the shares of which are traded on a national securities exchange, and registered open-end management investment companies, in each case, that (X) are either sponsored or managed by an entity listed on Schedule 2 to the Purchase Agreement or any other entity that is controlled by, controlling or under common control with an entity listed on Schedule 2 to the Purchase Agreement and (Y) invest primarily in municipal obligations (each, a "Registered Investment Company"); (b) banks or entities that are 100% direct or indirect subsidiaries of banks' publicly traded parent holding companies (collectively, "Banks"); or (c) insurance companies, in each case, pursuant to Rule 144A or another available exemption from registration under the Securities Act, in a manner not involving any public offering within the meaning of Section 4(a)(2) of the Securities Act, (ii) to tender option bond trusts (or other similar investment vehicles) in which all investors are Persons that the Transferor reasonably believes are QIBs that are Registered Investment Companies, Banks or insurance companies (or, in the case of a tender option bond trust (or other similar investment vehicles) in which the Holder or an affiliate of the Holder retains a residual interest), or (iii) to other investors with the prior written consent of the Issuer and (2) unless the prior written consent of each of the Issuer and the Majority Participants has been obtained, not to AllianceBernstein Persons if such AllianceBernstein Persons would, after such sale and transfer, own more than 20% of the Outstanding 2018 VMTP Shares.

6. The Transferee acknowledges that the 2018 VMTP Shares were issued in book-entry form and are represented by one global certificate and that the global certificate representing the 2018 VMTP Shares (unless sold to the public in an underwritten offering of the 2018 VMTP Shares pursuant to a registration statement filed under the Securities Act) contains a legend substantially to the following effect:

THE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAW. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION.

THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF AGREES TO SELL, TRANSFER OR OTHERWISE DISPOSE OF SUCH SECURITY ONLY IN WHOLE SHARES AND ONLY (1)(I) TO PERSONS THAT IT REASONABLY BELIEVES ARE QUALIFIED INSTITUTIONAL BUYERS ("QIBS") THAT ARE (A) REGISTERED CLOSED-END MANAGEMENT INVESTMENT COMPANIES, THE SHARES OF WHICH ARE TRADED ON A NATIONAL SECURITIES EXCHANGE, AND REGISTERED OPEN-END MANAGEMENT INVESTMENT COMPANIES, IN EACH CASE, THAT (X) ARE EITHER SPONSORED OR MANAGED BY AN ENTITY LISTED ON SCHEDULE 2 TO THE PURCHASE AGREEMENT OR ANY OTHER ENTITY THAT IS CONTROLLED BY, CONTROLLING OR UNDER COMMON CONTROL WITH AN ENTITY LISTED ON SCHEDULE 2 TO THE PURCHASE AGREEMENT AND (Y) INVEST PRIMARILY IN MUNICIPAL OBLIGATIONS (EACH, A "REGISTERED INVESTMENT COMPANY"); (B) BANKS OR ENTITIES THAT ARE 100% DIRECT OR INDIRECT SUBSIDIARIES OF BANKS' PUBLICLY TRADED PARENT HOLDING COMPANIES (COLLECTIVELY, "BANKS"); OR (C) INSURANCE COMPANIES, IN EACH CASE, PURSUANT TO RULE 144A OR ANOTHER AVAILABLE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT, IN A MANNER NOT INVOLVING ANY PUBLIC OFFERING WITHIN THE MEANING OF SECTION 4(a)(2) OF THE SECURITIES ACT, (II) TO TENDER OPTION BOND TRUSTS (OR OTHER SIMILAR INVESTMENT VEHICLES) IN WHICH ALL INVESTORS ARE PERSONS THAT THE HOLDER REASONABLY BELIEVES ARE QIBS THAT ARE REGISTERED INVESTMENT COMPANIES, BANKS OR INSURANCE COMPANIES (OR, IN THE CASE OF A TENDER OPTION BOND TRUST (OR OTHER SIMILAR INVESTMENT VEHICLES) IN WHICH THE HOLDER OR AN AFFILIATE OF THE HOLDER RETAINS A RESIDUAL INTEREST), OR (III) TO OTHER INVESTORS WITH THE PRIOR WRITTEN CONSENT OF THE FUND AND (2) UNLESS THE PRIOR WRITTEN CONSENT OF EACH OF THE FUND AND THE MAJORITY PARTICIPANTS HAS BEEN OBTAINED, NOT TO ALLIANCEBERNSTEIN PERSONS IF SUCH ALLIANCEBERNSTEIN PERSONS WOULD, AFTER SUCH SALE AND TRANSFER, OWN MORE THAN 20% OF THE OUTSTANDING 2018 VMTP SHARES.

ANY TRANSFER IN VIOLATION OF THE FOREGOING TRANSFER RESTRICTIONS WILL BE VOID AB INITIO AND ANY TRANSFEREE OF 2018 VMTP SHARES TRANSFERRED IN VIOLATION OF THE FOREGOING RESTRICTIONS SHALL BE DEEMED TO AGREE TO HOLD ALL PAYMENTS IT RECEIVED ON ANY IMPROPERLY TRANSFERRED 2018 VMTP SHARES IN TRUST FOR THE BENEFIT OF THE TRANSFEROR OF SUCH 2018 VMTP SHARES.

7. The Transferee has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Transferred Shares, and has so evaluated the merits and risks of such investment. The Transferee is able to bear the economic risk of an investment in the Transferred Shares and, at the present time, is able to afford a complete loss of such investment.

8. The Transferee is not purchasing the Transferred Shares as a result of any advertisement, article, notice or other communication regarding the Transferred Shares published in, nor was it offered the Transferred Shares by, any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or, to its knowledge, any other general solicitation or general advertisement.

9. Other than consummating the purchase of the Transferred Shares, the Transferee has not directly or indirectly, nor has any person acting on behalf of or pursuant to any understanding with the Transferee, executed any other purchases of securities of the Fund which may be integrated with the proposed purchase of the Transferred Shares by the Transferee.
