(b) Selection of Underwriter in Demand Registration. The Fund shall (together with all Holders proposing to distribute their securities through the underwriting) enter into an underwriting agreement in customary form for an underwritten offering of preferred stock made solely by selling shareholders (the “Underwriting Agreement”) with the underwriter or, if more than one, the lead underwriter acting as the representative of the underwriters (the “Underwriters’ Representative”) selected for the underwriting by the Holders of a majority of the Registrable Securities proposed to be underwritten and with the consent of the Fund, such consent not to be unreasonably withheld. The Underwriting Agreement shall provide that in connection with the distribution of Registrable Securities pursuant to the underwriting, no purchaser (other than any underwriters acting as initial purchasers in the underwriting) shall be permitted to acquire more than 25% of the Outstanding VMTP Preferred Shares from the underwriters.

(c) Marketing Limitation in Demand Registration. Notwithstanding any other provision of this Section 3, in the event the Underwriters’ Representative advises the Fund in writing that market factors (including, without limitation, the aggregate number of VMTP Preferred Shares requested to be Registered, the general condition of the market, and the status of the Persons proposing to sell securities pursuant to the Registration) require a limitation of the number of shares to be underwritten, then the Fund shall so advise the Designated Representative, and, if the Fund chooses to proceed with the Registration, the number of shares of Registrable Securities that may be included in the Registration and underwriting shall be allocated among all Holders of such Registrable Securities on a pro rata basis based on the number of Registrable Securities requested to be included in the Registration by all such selling Holders (including the Shareholder), provided, however, that the number of Registrable Securities to be included in any such underwriting held by Holders shall not be reduced unless all other Registrable Securities of the Fund, its Affiliates and BlackRock Persons, other than any account or Person that is an Affiliate of the Fund or a BlackRock Person solely because the Investment Adviser or its Affiliate is the investment adviser, manager, general partner of or otherwise exercises discretionary authority or control over such account or Person, are first entirely excluded from the underwriting. Unless the prior written consent of the Person holding a majority of the Registrable Securities to be included in the underwriting has been obtained, the number of the Registrable Securities included in any such underwriting shall not be reduced to less than 90% of the numbers of the Registrable Securities requested to be included. Any Registrable Securities or other securities excluded from the underwriting by reason of this Section 3.3(c) shall be withdrawn from the Registration. To facilitate the allocation of shares in accordance with the foregoing, the underwriters may round the number of shares allocated to any Holder to the nearest one share.

(d) Right of Withdrawal in Demand Registration. If any Holder of Registrable Securities (other than the Shareholder) desires, such Holder may elect to withdraw its Registrable Securities from sale thereunder in accordance with the Underwriting Agreement.

4. Expenses of Registration. All Registration Expenses incurred in connection with a Registration pursuant to Section 3.1 of this Agreement shall be split equally among the Fund and the Holders of Registrable Securities that are to be Registered; provided, that in the event of an Aborted Registration the Fund shall be obligated to pay 100% of any Registration Expenses incurred in connection with a subsequent Registration pursuant to Section 3.1 of this Agreement.

5. Assignability of Registration Rights; Termination of Registration Rights; Limitation on Subsequent Registration Rights

7. Indemnification.

7.1. Fund’s Indemnification of Holders. The Fund agrees to indemnify and hold harmless each Holder Indemnified Person from and against any losses, claims, damages, liabilities or expenses incurred by them (including reasonable fees and disbursements of outside counsel) which are related to or arise out of any untrue or alleged untrue statement of a material fact contained in a Registration Statement, any Prospectus or in any amendment or supplement thereto, or arise out of or relate to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except insofar as such loss, claim, damage, liability or expense arises out of or is based upon (a) any untrue statement or allegedly untrue statement or omission or alleged omission made in such Registration Statement, Prospectus or supplement thereto in reliance upon and in conformity with information furnished in writing to the Fund by the underwriter or any Holder expressly for use therein, or (b) the use of a Registration Statement or Prospectus during a period when the Designated Representative has been notified that a stop order has been issued in respect thereof or any proceeding for that purpose has been initiated, or the use of a Registration Statement or Prospectus has been suspended by the Fund pursuant to the terms of this Agreement. The foregoing indemnity shall not inure to the benefit of any Holder Indemnified Person from whom the person asserting losses, claims, damages, liabilities or expenses purchased Registrable Securities, if a copy of the Prospectus (as then amended or supplemented if the Fund shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Holder Indemnified Person to such person, if required by law so to have been delivered at or prior to the written confirmation of the sale of Registrable Securities to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such losses, claims, damages, liabilities or expenses, unless such failure is the result of noncompliance by the Fund with Section 6(b) of this Agreement.

7.2. Holders’ Indemnification of the Fund. Each Holder will, with respect to a Registration Statement where Registrable Securities were registered under the Securities Act, indemnify and hold harmless the Fund, each of the Fund’s directors and officers, and each other person, if any, who controls the Fund (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) (each, a “Fund Indemnified Persons”), against any losses, claims, damages, liabilities or expenses, whether joint or several, insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or allegedly untrue statement of a material fact contained in a Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any Prospectus or supplement thereto contained in such Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or the alleged omission to state a material fact required to be stated therein or necessary to make the statement therein not misleading, if the statement or omission was made in reliance upon and in conformity with information furnished in writing to the Fund by the Holder expressly for use therein. Each Holder’s indemnification obligations hereunder shall be limited to the amount of any net proceeds actually received by such Holder.

- 11 -

7.3. Indemnification Procedure. If any action, suit, proceeding or investigation shall be brought or asserted against any indemnified person, such indemnified person shall, if a claim in respect thereof is to be made against any indemnifying person under this Section 7, notify the indemnifying person in writing with reasonable promptness. The failure to deliver written notice to the indemnifying person within a reasonable time of the commencement of any such action, if materially prejudicial to its ability to defend such action, shall relieve such indemnifying person of any liability to the indemnified party under this Section 7, but the omission so to deliver written notice to the indemnifying person shall not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 7. The indemnifying person 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 separate 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 person 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 person 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 person.

The indemnifying person shall not be liable for any settlement of any such Proceeding effected without its prior written consent. The indemnifying person will not, without the prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, of the indemnified persons, 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 by the indemnified persons hereunder (whether or not the indemnifying 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 indemnified person from all liability and obligations arising therefrom.

7.4. Contribution. To the extent that the indemnification sought by indemnified persons pursuant to this Agreement is unavailable to an indemnified person or insufficient in respect of any losses, claims, damages or liabilities (or actions in respect thereof), then the indemnifying person, in order to provide for just and equitable contribution and in lieu of indemnifying such indemnified person, shall contribute to the amount paid or payable by such indemnified persons as a result of such losses, claims, liabilities, damages and expenses (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the indemnifying person on the one hand and the indemnified person(s) on the other, as well as any other relevant equitable considerations. 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.

- 12 -

7.5. No Limitations. Nothing in this Section 7 is intended to limit any party’s obligations contained in other parts of this Agreement or the VMTP Preferred Shares, provided that no amount shall be reimbursed twice in any event.

7.6. Conflicts. Notwithstanding the foregoing, to the extent that provisions on indemnification and contribution contained in the Underwriting Agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the Underwriting Agreement shall control.

8. Miscellaneous.

8.1. Governing Law. This Agreement shall be construed in accordance with and governed by the domestic law of the State of New York.

THE PARTIES HERETO HEREBY SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF THE FEDERAL AND NEW YORK STATE COURTS LOCATED IN THE CITY OF NEW YORK IN CONNECTION WITH ANY DISPUTE RELATED TO THIS AGREEMENT OR ANY MATTERS CONTEMPLATED HEREBY.

8.2. No Waivers. No failure or delay by the Fund or the Shareholder in exercising any right, power or privilege hereunder or under the VMTP Preferred 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 Fund or the Shareholder in exercising any right, power or privilege under or in respect of the VMTP Preferred Shares shall affect the rights, powers or privileges of the Fund or the Shareholder 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.

8.3. Specific Performance. Each Party hereby acknowledges that the remedies at law of the other Party for a breach or threatened breach of this Agreement would be inadequate and, in recognition of this fact, any Party, without posting any bond, and in addition to all other remedies that may be available, shall be entitled to seek equitable relief in the form of specific performance, injunctions or any other equitable remedy.

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

8.5. Counterparts and Facsimile Execution.
