TENDER OFFER AND STANDSTILL AGREEMENT

This Agreement (“Agreement”) is made and entered into as of the 18th day of September, 2014, by and among PIMCO Income Strategy Fund (“PFL”), PIMCO Income Strategy Fund II (“PFN” and, together with PFL, each a “Fund” and, collectively, the “Funds”), Allianz Global Investors Fund Management LLC (“AGIFM”), Pacific Investment Management Company LLC (“PIMCO” and, together with PFL, PFN and AGIFM, the “Fund Parties”) and Brigade Capital Management, LP (“Brigade Capital”), Brigade Leveraged Capital Structures Fund Ltd. (“Brigade Fund”) and Donald E. Morgan, III (“Morgan” and, together with Brigade Capital and Brigade Fund, the “Brigade Parties”).

WHEREAS, the Brigade Parties and their affiliates (together, “Brigade”) are substantial holders of auction rate preferred shares (“ARPS”) issued by PFL and PFN, each a closed-end investment company registered under the Investment Company Act of 1940 for which AGIFM served as investment manager and PIMCO served as sub-adviser for periods prior to the close of business on September 5, 2014 and for which PIMCO currently serves as investment manager;

WHEREAS, the Brigade Parties have engaged in discussions with the Fund Parties regarding the Brigade Parties’ proposal that the Funds pursue leverage alternatives for the outstanding ARPS of the Funds, including a proposal that each Fund conduct an issuer tender offer for its ARPS, and in that connection entered into a letter agreement dated May 8, 2014, as amended on May 29, 2014, regarding confidentiality obligations with respect to the discussions (together, the “Discussions”);

WHEREAS, Alan Miller and Marti Murray (the “Brigade Trustees”) have each been elected to the Boards of Trustees of PFL and PFN (each, a “Board”) by ARPS holders voting as a separate class at the nomination of Brigade for terms corresponding with the Funds’ Bylaws;

WHEREAS, the Fund Parties and the Brigade Parties have entered into a separate letter agreement dated August 20, 2014 (the “Confidentiality Letter Agreement”) regarding confidentiality obligations with respect to a continuation of the Discussions;

WHEREAS, the parties wish to resolve various matters associated with the Discussions, the Brigade Trustees, former Trustees of the Funds nominated by Brigade and Brigade’s holdings of the Funds’ ARPS.

NOW, THEREFORE, in consideration of the mutual promises and covenants contained in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

1.     Tender Offers. With respect to each Fund, subject to satisfaction of Section 2(a) below, the Fund Parties (each Fund with respect to itself only) agree to conduct a tender offer by the Fund for 100% of its issued and outstanding ARPS at a price equal to 90% of the $25,000 per share liquidation preference of the ARPS (i.e., a tender offer of $22,500 per ARPS share), plus one non-transferrable contingent payment right, which represents the contractual right to receive the consideration (if any becomes payable) described in the following paragraph, scheduled to expire as of the close of the New York Stock Exchange on October 31, 2014 (such date, as it

may be extended in accordance with the terms of the Tender Offers, the “Expiration Date”), subject only to substantially the same conditions as are set forth in Appendix A hereto (the “Tender Offers”), which conditions do not include any minimum level of participation in the Tender Offer by ARPS holders of the Fund. Each Fund (with respect to itself only) hereby agrees that if, as of the Expiration Date of its Tender Offer, all of such conditions are satisfied, it shall accept for payment all ARPS properly tendered pursuant to its Tender Offer.

In addition, subject to satisfaction of Section 2(a) below, with respect to each Fund, the Fund Parties (each Fund with respect to itself only) agree that, if a Fund completes its Tender Offer and subsequently completes an additional tender offer for its ARPS or a voluntary redemption of its ARPS pursuant to Section 11.4(a)(i) of the Fund’s Bylaws (as opposed to and not including a mandatory ARPS redemption pursuant to Section 11.4(a)(ii) of the Fund’s Bylaws) (collectively such an additional ARPS tender offer or voluntary redemption of ARPS being referred to herein as a “Voluntary Redemption”) during the period of three-hundred and sixty-five (365) calendar days beginning with the Expiration Date of the Fund’s Tender Offer (such 365 calendar day period is referred to herein as such Fund’s “Subsequent Year”) and such subsequent Voluntary Redemption is for a tender offer or redemption price per ARPS share that is greater than the price per ARPS share paid in the Fund’s Tender Offer (the amount of such price differential per ARPS share, the “Additional Amount”), the Fund will pay to Brigade and any other ARPS holder who has tendered and received payment for ARPS in the Fund’s Tender Offer an additional payment equal to (i) the number of ARPS so tendered by such holder in the Tender Offer multiplied by (ii) the Additional Amount. Payment of the Additional Amount per ARPS share shall be made within thirty (30) days of the event that gave rise to such payment.

For purposes of this Agreement, the date upon which a Fund “completes,” “completed” or the “completion of” a tender offer or redemption for its ARPS means the date upon which the Fund makes payment for all validly tendered ARPS that have been accepted for payment in such tender offer or for all ARPS that have been redeemed pursuant to a redemption. For the sake of clarity, a Fund’s Tender Offer shall be deemed “completed” for purposes of this Agreement on the date upon which a Fund makes payment for all validly tendered ARPS that have been accepted for payment in such Tender Offer, and such Tender Offer shall not be integrated with or deemed to continue in the event that the Fund engages in a subsequent Voluntary Redemption and/or is required to make a payment of an Additional Amount with respect to such Tender Offer pursuant to the immediately preceding paragraph. In this regard, a Fund’s Subsequent Year (which shall begin on the Expiration Date of such Fund’s Tender Offer) shall not be extended for any reason and shall not relate to or recommence in connection with a subsequent Voluntary Redemption or other tender offer or redemption conducted by the Fund.

2.     Agreements and Obligations of the Brigade Parties. The Brigade Parties hereby agree and undertake that:

(a)     As a condition to the Fund Parties’ obligations in Section 1, the Brigade Parties shall recommend, and each Brigade Trustee shall have delivered on or prior to the date of this Agreement, his or her resignation as a Trustee of PFL and PFN, with such resignation to be conditioned upon and to take effect as of the completion of the particular Fund’s Tender Offer.

(b)     With respect to each Fund, if a Tender Offer is conducted by the Fund, Brigade

shall tender one-hundred percent (100%) of its holdings in ARPS of the Fund, such that Brigade would have no holdings in the Fund’s ARPS following completion of the Fund’s Tender Offer.

(c)     The Brigade Parties shall, for a period of three (3) years from and after the date that a Fund’s Tender Offer is completed, (i) refrain from directly or indirectly making or supporting any shareholder proposals concerning the Funds including, without limitation, any nomination of a candidate for Trustee of the Funds, (ii) vote in accordance with the applicable Board’s and management’s recommendations on any matters affecting the Funds (except as noted below in the proviso to subparagraph (d)(ii), which shall apply to the Brigade Parties’ obligations with respect to the Funds in this subparagraph (c)(ii)), (iii) refrain from directly or indirectly soliciting or encouraging others to vote against the applicable Board’s and management’s recommendations on any matters affecting the Funds; and (iv) refrain from directly or indirectly proposing, or making any filing with respect to, any form of business combination, restructuring, recapitalization, dissolution or similar transaction involving the Funds, including, without limitation, a merger, tender or exchange offer, open-ending, share repurchase or liquidation of a Fund’s assets.

(d)     The Brigade Parties shall, for a period of three (3) years from and after the date that a Fund’s Tender Offer is completed, (i) refrain from directly or indirectly making or supporting any shareholder proposals concerning any other existing or future investment company advised, sub-advised, distributed or sponsored by AGIFM, PIMCO or their affiliates (“Other Allianz or PIMCO Funds”) including, without limitation, any nomination of a candidate for trustee or director of the Other Allianz or PIMCO Funds, (ii) vote in accordance with the applicable board of trustees/directors’ (or similar body, a “board”) and management’s recommendations on any matters affecting Other Allianz or PIMCO Funds; provided that the Brigade Parties shall not be so obligated if (x) the Brigade Parties determine that the applicable board’s or management’s recommendation would be contrary to a previously established policy adopted by the Brigade Parties not solely relating to the Other Allianz or PIMCO Funds, (y) the Brigade Parties determine that the fiduciary duties owed by the Brigade Parties to the beneficial owners of the equity securities of the Other Allianz or PIMCO Funds over which the Brigade Parties have voting authority would require the Brigade Parties to vote in a manner that differs from the applicable board’s or management’s recommendation, or (z) the Brigade Parties do not have voting authority over the equity securities of the Other Allianz or PIMCO Funds held by the Brigade Parties, (iii) refrain from directly or indirectly soliciting or encouraging others to vote against the applicable board’s and management’s recommendations on any matters affecting Other Allianz or PIMCO Funds; and (iv) refrain from directly or indirectly proposing, or making any filing with respect to, any form of business combination, restructuring, recapitalization, dissolution or similar transaction involving Other Allianz or PIMCO Funds, including, without limitation, a merger, tender or exchange offer, open-ending, share repurchase or liquidation of the assets of Other Allianz or PIMCO Funds. Notwithstanding the foregoing, the defined term “Other Allianz or PIMCO Funds” as used in this Section 2(d) shall not include PIMCO Corporate & Income Opportunity Fund (“PTY”) and, accordingly, this Section 2(d) shall not be applicable to PTY, or to PIMCO solely in its capacity as investment manager to PTY, in any respect.

(a)     Subject to and upon completion of the Tender Offers, each of the Brigade Parties, on behalf of itself, its heirs, beneficiaries, administrators, personal representatives, successors, assigns, parents, subsidiaries, shareholders, affiliates, and predecessors, as applicable, in exchange for the agreements and other consideration in this Agreement, (i) does hereby compromise, settle, and absolutely, unconditionally, and fully release and forever discharge each of the Fund Parties and their current and former respective successors, subsidiaries, affiliates, employees, officers, directors, trustees, managers, investors and shareholders, and each of their respective attorneys, administrators, personal representatives, insurers and assigns (together, the “Released Fund Parties”) of and from any and all claims, demands, debts, liens, obligations, fees and expenses (including attorneys’ fees and expenses related to any previously completed or ongoing litigation involving the parties), harm, injuries, liabilities, cause or causes of action, whether known or unknown, claimed or alleged, asserted or unasserted, either at law or in equity, whether statutory, in contract or in tort, of any kind or character which it has, or owns, or may now or in the future have or own for any claims arising out of or relating in any way to the Discussions, the Brigade Trustees or former Trustees of the Funds nominated by Brigade or their nominations or elections, the Tender Offers or Brigade’s acquisition of, transactions in, ownership of or holdings in the Funds’ ARPS and (ii) acknowledges and agrees that it will not now or in the future bring any claim, action, lawsuit, arbitration proceeding or other form of action against any of the Released Fund Parties, directly or indirectly, arising out of or in any way connected with any claim or potential claim released under this Agreement as referenced in sub-paragraph 3(a)(i) above, and that this Agreement is a bar to any such claim, action, lawsuit, proceeding or other form of action.

(b)     Subject to and upon completion of the Tender Offers, each of the Fund Parties, on behalf of itself, its heirs, beneficiaries, administrators, personal representatives, successors, assigns, parents, subsidiaries, shareholders, affiliates, and predecessors, as applicable, in exchange for the agreements and other consideration in this Agreement, (i) does hereby compromise, settle, and absolutely, unconditionally, and fully release and forever discharge each of the Brigade Parties and their current and former respective successors, subsidiaries, affiliates, employees, officers, directors, trustees, managers, investors and shareholders, the individuals nominated in the past by Brigade for election to the Boards, and each of their respective attorneys, administrators, personal representatives, insurers and assigns (together, the “Released Brigade Parties”) of and from any and all claims, demands, debts, liens, obligations, fees and expenses (including attorneys’ fees and expenses related to any previously completed or ongoing litigation involving the parties), harm, injuries, liabilities, cause or causes of action, whether known or unknown, claimed or alleged, asserted or unasserted, either at law or in equity, whether statutory, in contract or in tort, of any kind or character which it has, or owns, or may now or in the future have or own for any claims arising out of or relating in any way to the Discussions, the Brigade Trustees or former Trustees of the Funds nominated by Brigade or their nominations or elections, the Tender Offers or Brigade’s acquisition of, transactions in, ownership of or holdings in the Funds’ ARPS and (ii) acknowledges and agrees that it will not now or in the future bring any claim, action, lawsuit, arbitration proceeding or other form of action against any of the Released Brigade Parties, directly or indirectly, arising out of or in any way connected with any claim or potential claim released under this Agreement as referenced in sub-paragraph 3(b)(i) above, and that this Agreement is a bar to any such claim, action, lawsuit, proceeding or other

form of action.

(c)     For the avoidance of doubt, the provisions of Section 3(a) and Section 3(b) shall not apply to PTY, or to PIMCO solely in its current capacity as investment manager of PTY or to AGIFM and PIMCO solely in their former capacities as investment manager and sub-adviser, respectively, to PTY.

(d)     The Brigade Parties and the Fund Parties acknowledge and agree that the releases and covenants provided in this Section 3 are in no way an admission or acknowledgment of any liabilities, claims or causes of action that one party may have against the other.

(e)     The provisions of Section 3(a) and Section 3(b) shall not be deemed to preclude any claim by any party hereto alleging a breach of the terms of this Agreement.

4.     No Disparagement. For a period of three (3) years from and after the date of this Agreement, the Brigade Parties, on the one hand, and the Fund Parties, on the other hand, shall refrain from directly or indirectly disparaging, impugning, or taking any action reasonably likely to damage the reputation of the other party or its employees or affiliates or the current and former Trustees or officers of the Funds with respect to the subject matter of the Discussions, the Brigade Trustees or former Trustees of the Funds nominated by Brigade or their nominations or elections, the Tender Offers or Brigade’s holdings in the Funds’ ARPS, including relating to prior discussions, actions and communications regarding leverage alternatives, prior litigation and related outcomes, the subject matter of proxy contests and Fund governance, management, performance, compliance and related topics. The foregoing shall not apply to any compelled testimony or production of information, either by legal process, subpoena, or as part of a response to a request for information from any governmental authority with jurisdiction over the party from whom information is sought. For the avoidance of doubt, the provisions of this Section 4 shall not apply to PTY, or to PIMCO solely in its current capacity as investment manager of PTY or to AGIFM and PIMCO solely in their former capacities as investment manager and sub-adviser, respectively, to PTY.

5.     Injunctive Relief. Each party acknowledges that a breach of its obligations under this Agreement may result in irreparable harm to the other party for which monetary damages will not be sufficient. Each party hereto agrees that, in the event of a breach or threatened breach by the other party of its obligations under this Agreement, the non-breaching party shall be entitled, in addition to its other rights and remedies hereunder or at law, to injunctive or other equitable relief, and such further relief as may be proper from a court of competent jurisdiction, including specific performance of the obligations set forth in Section 2 of this Agreement.

6.     Confidentiality. The Brigade Parties and the Fund Parties hereby agree to and do hereby extend the term of the Confidentiality Letter Agreement and their respective obligations thereunder in accordance with Section 7 hereof; provided that the Fund Parties may disclose the subject matter of the Tender Offers to third parties, including to other holders of the Funds’ ARPS and to service providers and agents who may be engaged to assist in conducting the Tender Offers, before the Tender Offers are publicly announced. For the avoidance of doubt, the Fund Parties acknowledge that the Brigade Parties will be required to file a copy of this Agreement on an amendment to Schedule 13D, and the Brigade Parties acknowledge that the

Funds will be required to file a copy of this Agreement with their respective Form TO filings in connection with the Tender Offers.

7.     Term. This Agreement shall terminate on the earlier of (i) September 30, 2014, if the Funds have not on or before that date commenced the Tender Offers, (ii) the close of the New York Stock Exchange on the business day next following the Expiration Date, if the Funds have not accepted validly tendered ARPS for purchase pursuant to the Tender Offers by such time and (iii) the date of completion of the Tender Offers. In the case of termination of this Agreement pursuant to Section 7(i) and Section 7(ii), all provisions of this Agreement shall terminate and have no further force or effect upon such termination, except that the confidentiality obligations of the parties under Section 6 hereof and the Confidentiality Letter Agreement shall survive the termination of this Agreement. In the case of termination of this Agreement pursuant to Section 7(iii), the obligations of the parties under Sections 1, 2, 3, 4, 5, 6 and 8 hereof shall survive the termination of this Agreement.

8.     Non-Binding Discussions Regarding PTY. One or more of the Brigade Parties is currently a holder of ARPS issued by PTY. PIMCO and the Brigade Parties agree to engage in non-binding discussions regarding possible leverage alternatives for the outstanding ARPS of PTY (the “PTY Discussions”) during a two-month period, which two-month period will commence with the date of this Agreement (the “PTY Discussions Period”), it being understood that PIMCO will be under no obligation to take any action, including to recommend any such leverage alternatives to PTY or PTY’s Board of Trustees, as a result of such PTY Discussions. For purposes of clarity, none of PIMCO, PTY or PTY’s Board of Trustees, on the one hand, or the Brigade Parties, on the other hand, shall be obligated in any way by such PTY Discussions, and the PTY Discussions are not intended to, and they will not, create any fiduciary or other special duties or obligations between the parties hereto; any binding agreement or obligation related to PTY subsequently agreed to between PIMCO and PTY on the one hand, and such Brigade Parties, on the other hand, must be in the form of a separate duly executed written agreement (a “PTY Agreement”). Without limiting the generality of the foregoing, each of the parties hereto agrees on behalf of itself and its affiliates not to institute or maintain any claim, action, lawsuit, arbitration proceeding or other form of action which seeks to establish, or which is otherwise based upon an assertion, that any contractual relationship exists with respect to PTY as a consequence of the PTY Discussions, except pursuant to a PTY Agreement, if negotiated, duly executed and delivered by the parties. The Brigade Parties acknowledge that any PTY Agreement would require the approval of the PTY’s Board of Trustees. Prior to the commencement of the PTY Discussions Period, PIMCO and the Brigade Parties shall enter into a separate confidentiality agreement with respect to the PTY Discussions that is mutually acceptable to PIMCO and the Brigade Parties, which will be coterminous with the PTY Discussions Period and the terms of which will be substantively similar to the Confidentiality Letter Agreement.

9.     Miscellaneous.

Any notices or other communications required or permitted hereunder will be deemed to have been properly given and delivered if in writing by such party or its legal representative and delivered personally or sent by facsimile, e-mail or other electronic communication, or by a nationally recognized overnight courier service guaranteeing overnight

(c)     Agreement Separable. If any provision hereof is for any reason unenforceable or inapplicable, the other provisions hereof will remain in full force and effect in the same manner as if such unenforceable or inapplicable provision had never been contained herein.

The parties agree that any of them may file a copy of this Section 9(e) with any court as written evidence of the knowing, voluntary and bargained-for agreement between the parties each irrevocably to waive its right to trial by jury in any proceeding whatsoever between them relating to this Agreement, which will instead be tried in a court of competent jurisdiction by a judge sitting without a jury.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above, and each party represents and acknowledges that it possesses the requisite authority to execute this Agreement.

APPENDIX A
