3.1. Request for Registration. If the Fund receives from the Majority Holders (referred to as the "Initiating Holder(s)") a request in writing that the Fund effect any Registration with respect to the Registrable Securities, subject to the terms of this Agreement, the Fund shall (i) within ten (10) days of receipt of such written request, give written notice of the proposed Registration to all other Holders, and (ii) as soon as practicable, use its commercially reasonable best efforts to file a Registration Statement with respect to those Registrable Securities ("Demand Registration") which the Fund has been so requested to register, together with all other Registrable Securities which the Fund has been requested to register by Holders thereof by written request given to the Fund within fifteen (15) days after receiving written notice from the Fund, subject to the limitations of this Section 3. The Fund shall not be obligated to take any action to effect any Registration pursuant to this Section 3.1 after the Fund has effected one Registration pursuant to this Section 3.1 and such Registration has been declared or ordered effective (and has not been subject to a "stop order" of the Commission). The substantive provisions of Section 3.3 shall be applicable to any Registration initiated under this Section 3.1.

3.2. Right of Deferral. Notwithstanding the foregoing, the Fund shall not be obligated to file a Registration Statement pursuant to this Section 3 or take any action pursuant to Section 6 if the Fund furnishes to those Holders a certificate signed by the president or chairman of the Board of the Fund stating that in the good faith judgment of the Board it would be materially detrimental to the Fund or its shareholders for a Registration Statement to be filed in the near future. In such event, the Fund's obligation to use its commercially reasonable best efforts to file a Registration Statement shall be deferred for a period not to exceed 90 days from the receipt of the request to file the registration by that Holder; provided, that the Fund shall not exercise the right to delay a request contained in this Section 3.2 more than once in any 12 month period, and provided further, that during such 90 day period, the Fund shall not file a Registration Statement with respect to any preferred shares of the Fund except as otherwise may be agreed in writing by the Parties; and provided further, that notwithstanding anything to the contrary contained herein, the Fund shall not be required to file a Registration Statement at any time when the Fund reasonably believes upon the advice of counsel that doing so would violate applicable law or the rules and regulations of the Securities and Exchange Commission or other regulatory entity.

3.3. Underwriting in Demand Registration.

(a) Notice of Underwriting. If the Initiating Holder(s) intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Fund as a part of their request made pursuant to this Section 3, and the Fund shall include that information in the written notice referred to in Section 3.1 of this Agreement. The right of any Holder to have their Registrable Securities included in a Registration pursuant to this Section 3 shall be conditioned upon such Holder's agreement to participate in the underwriting and the inclusion of that Holder's Registrable Securities in the underwriting to the extent provided herein.

(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 made solely by selling shareholders 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 Initiating Holder and with the consent of the Fund, not to be unreasonably withheld.

(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 RVMTP Shares requested to be Registered, the general condition of the market, and/or 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 all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and 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 Initiating Holder(s)); 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 securities of the Fund, its Affiliates and PIMCO Persons are first entirely excluded from the underwriting. Unless the prior written consent of the Majority Holders has been obtained, the number of the Registrable Securities included in any such underwriting shall not be reduced to less than 90% of the number 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 Fund or 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 Initiating Holder(s)) disapproves of the terms of the underwriting, such Holder may elect to withdraw therefrom by written notice to the Fund and the Underwriters' Representative proposing to distribute their securities through the underwriting, delivered at least twenty (20) days prior to the effective date of the Registration Statement. If any Initiating Holder elects to withdraw, such withdrawal shall be conditioned on the payment by such withdrawing Initiating Holder to the Fund of the Registration Expenses incurred in connection with such withdrawal (which Registration Expenses are to be calculated on a per share basis according to the total Registration Expenses then incurred and the total number of Registrable Securities and, once calculated, such allocation of the Registration Expenses to the withdrawal to be made proportionally based on the number of withdrawn securities to the total number of Registrable Securities). Such payment obligation shall be allocated severally among the withdrawing Initiating Holders (such allocation to be made proportionally among the withdrawing Initiating Holders based on the number of withdrawn securities held by each of such holders and the total number of withdrawn securities held by all withdrawing Initiating Holders), and the payment shall be made within thirty (30) days after the delivery to the withdrawing Initiating Holders of an invoice stating such Registration Expense in reasonable detail. The securities so withdrawn shall also be withdrawn from the Registration Statement.

4. Expenses of Registration. All Registration Expenses incurred in connection with any Registration pursuant to Section 3.1 shall be borne by the Fund.

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

5.1. Assignability of Registration Rights. Except as provided in Section 8.11, no Party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the written consent of the other Party to this Agreement.

5.2. Termination of Registration Rights. The rights to cause the Fund to register Registrable Securities granted under Section 3 of this Agreement and to receive notices pursuant to Section 3 of this Agreement, shall terminate on the earliest of (i) the date that is twelve (12) months prior to the then current Term Redemption Date or Early Term Redemption Date (each as defined in the Statement), (ii) a notice of redemption having been issued by the Fund under the Statement for the redemption of all of the Registrable Securities unless a Redemption Default (as defined in the Statement) has occurred and remains outstanding, or the repurchase by the Fund (including by exchange of securities) and cancellation of all of the Registrable Securities and (iii) the date a Demand Registration has been effected and the Registrable Securities have been sold or otherwise disposed of in accordance with the plan of distribution set forth in the Registration Statement and Prospectus relating thereto or all Holders have withdrawn from the Demand Registration.

If any action, suit, proceeding or investigation shall be brought or asserted against any Person entitled to indemnity hereunder (the "Indemnified Party"), such Indemnified Party shall notify the Person from whom indemnity is sought (the "Indemnifying Party") in writing with reasonable promptness; provided, however, that any failure by an Indemnified Party 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 Party. The Indemnified Party 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 Party unless (i) the Indemnifying Party has failed promptly to assume the defense and employ counsel reasonably satisfactory to the Indemnified Party in accordance with the preceding sentence or (ii) the Indemnified Party shall have been advised by counsel that there exist actual or potential conflicting interests between the Indemnifying Party and such Indemnified Party, including situations in which one or more legal defenses may be available to such Indemnified Party 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 Parties of the 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.

The Indemnifying Party shall not be liable for any settlement of any such action, suit, proceeding or investigation effected without its written consent, which consent shall not be unreasonably withheld, conditioned or delayed. No Indemnifying Party will, without the prior written consent of the Indemnified Party, settle or compromise or consent to the entry of any judgment in any pending or threatened action, suit, proceeding or investigation in respect of which indemnification may be sought by the Indemnified Party hereunder (whether or not any Indemnified Party is an actual or potential party to such action, suit, proceeding or investigation) unless such settlement, compromise or consent includes an unconditional release of each Indemnified Party from all liability and obligations arising therefrom.

7.4. Contribution. Each Indemnifying Party also agrees that if any indemnification sought by an Indemnified Party pursuant to this Agreement is unavailable or insufficient, for any reason, to hold harmless the Indemnified 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 Party 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 Fund on the one hand and the Holders 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. 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 Fund on the one hand, or the Holder 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. In no event shall the liability of any selling Holder under this Section 7.4 be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such contribution obligation, except in the case of fraud or willful misconduct. The indemnity, reimbursement and contribution obligations under this Agreement shall be in addition to any rights that any Indemnified Party may have at common law or otherwise.

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 RVMTP 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.

(a)

The obligations of the Fund and the Shareholder and its Permitted Transferees hereunder shall not in any way be modified or limited by reference to any other document, instrument or agreement (including, without limitation, the RVMTP Shares). The rights of the Shareholder hereunder are separate from and in addition to any rights that any Holder of any RVMTP Share may have under the terms of such RVMTP Share or otherwise.

(b)

No failure or delay by the Fund or the Shareholder in exercising any right, power or privilege hereunder or under the RVMTP Shares or any other agreement 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 RVMTP Shares or any other agreement 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 Parties 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 Trial. 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. 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 electronic mail shall be deemed for all purposes as being a good and valid execution and delivery of this Agreement by that Party. Moreover, the parties hereto further acknowledge and agree that this Agreement may be signed and/or transmitted by e-mail or a .pdf document or using electronic signature technology (e.g., via DocuSign, Adobesign, or other electronic signature technology), and that such signed electronic record shall be valid and as effective to bind the Party so signing as a paper copy bearing such Party’s handwritten signature. The parties further consent and agree that (i) to the extent a Party signs this Agreement using electronic signature technology, by clicking "SIGN", such Party is signing this Agreement electronically; and (ii) the electronic signatures appearing on this Agreement shall be treated, for purposes of validity, enforceability and admissibility, the same as handwritten signatures.

Any assignment without such prior written consent shall be void.

8.12. Transfers to TOBs.

8.13. Effectiveness of this Agreement. This Agreement shall be effective as of the Effective Date and the rights and obligations of the Parties contained herein in each case shall be binding as of the Effective Date.

8.14. No Individual Liability.

In accordance with the Agreement and Declaration of Trust of the Fund, no trustee, shareholder, officer, employee or agent of the Fund shall be held to any personal liability, nor shall resort be had to their private property for the satisfaction of any obligation or claim or otherwise under this Agreement, and the Fund shall be solely liable therefor and all parties hereto shall look solely to the Fund's property for the payment of any claim, or the performance of any obligation, hereunder.
