FORM OF DISTRIBUTION AGREEMENT

This DISTRIBUTION AGREEMENT (this “Agreement”) made as of February 24, 2025 by and between Calamos Convertible Opportunities and Income Fund, a Delaware statutory trust (the “Fund”), and Foreside Fund Services, LLC, a Delaware limited liability company (the “Distributor”).

WITNESSETH:

WHEREAS, the Fund is registered under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder (collectively called the “Investment Company Act”), as a diversified, closed-end, management investment company; and

WHEREAS, the Fund has filed a registration statement on Form N-2 pursuant to the Investment Company Act and the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively called the “Securities Act”), to register common shares of beneficial interest, no par value per share, of the Fund (the “Common Shares”), which may be issued and sold from time to time through various specified transactions, including at-the-market (“ATM”) offerings pursuant to Rule 415 under the Securities Act; and

WHEREAS, the Distributor is registered as a broker-dealer under the provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the “Exchange Act”), and is a member in good standing of the Financial Industry Regulatory Authority, Inc. (“FINRA”); and

WHEREAS, the Fund and the Distributor wish to enter into an agreement with each other with respect to ATM offerings, from time to time, of the Common Shares.

NOW THEREFORE, the parties agree as follows:

Section 1. Appointment of the Distributor; ATM Offerings.

(a) Subject to the terms and conditions of this Agreement, the Fund hereby appoints the Distributor as its principal underwriter and placement agent for up to 17,435,035 Common Shares of the Fund to be offered pursuant to the Registration Statement (as defined herein) through ATM offerings from time to time (the “Shares”) and the Fund agrees that it will issue such Shares as the Distributor may sell. The Distributor agrees to enter into sub-placement agent agreements with selected dealers, each of whom shall be registered as a broker-dealer under the provisions of the Exchange Act and a member in good standing of FINRA who will use reasonable efforts to identify opportunities for the sale of Shares (each, a “sub-placement agent”), but neither the Distributor nor any sub-placement agent is obligated to sell any specific number of the Shares (though the Distributor will only be authorized to sell on any Offering Date, subject to the terms and conditions contained herein, the maximum number of Shares agreed to with the Fund pursuant to Section 1(d) hereof). The Distributor will not purchase any Shares for its own account. The Shares will only be sold on such days as shall be agreed to by the Distributor and the Fund (each, an “Offering Date”). The Distributor hereby accepts such appointment.

(b) The Distributor acknowledges that Shares will be offered and sold only as set forth from time to time in the Registration Statement including, without limitation, pricing of Shares, handling of investor funds and payment of sales commissions.

(c) The Fund may suspend or terminate any ATM offering of its Shares at any time. Upon notice to the Distributor of the terms of such suspension or termination, the Distributor shall suspend the ATM offering of Shares in accordance with such terms until the Fund notifies the Distributor that such ATM offering may be resumed; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Shares sold hereunder prior to the giving of such notice.

(d) The price per Share shall be determined by the Fund together with the Distributor or any sub-placement agent by reference to trades in the Common Shares on the primary exchange for the Common Shares. In no event shall the price per Share be less than the then current net asset value per Common Share (which net asset value shall be determined as of a time within forty-eight hours, excluding Sundays and holidays, next preceding the time of such determination) plus the per Share amount of the commission to be paid to the Distributor (the “Minimum Price”). The Fund may establish a minimum sales price per Share on any Offering Date in excess of the Minimum Price (the “Minimum Sales Price”), and the Fund shall communicate such Minimum Sales Price to the Distributor. The Fund shall have sole discretion to establish a Minimum Sales Price for any Offering Date and may consider, among other factors, the degree to which the market price per Common Share exceeds the Fund’s net asset value per Common Share, and the amount of assets the Fund desires to raise through ATM offerings. The Distributor shall suspend the sale of Shares if the per share price of the Shares is less than the Minimum Price or the Minimum Sales Price. The Distributor or any sub-placement agent shall, together with the Fund, determine the maximum number of Shares to be sold through the Distributor or through such sub-placement agent for any Offering Date, and the Distributor or such sub-placement agent shall not be authorized to sell Shares on any Offering Date in excess of such maximum.

(e) The Distributor will confirm to the Fund, following the close of trading on the Fund’s primary exchange on each Offering Date for the Shares, the number of Shares sold through the Distributor and through any sub-placement agent, the time of sale, the gross sales price per Share and the compensation payable to the Distributor and such sub-placement agent, or to which the Distributor and such sub-placement agent are entitled with respect to such sales. The Fund reserves the right to reject any order in whole or in part.

(f) Settlement for sales of the Shares pursuant to this Section 1 will occur on the business day following the date on which such sales are made (each such day, a “Settlement Date”), unless otherwise agreed to in writing by the parties hereto. On each Settlement Date, the Shares sold through the Distributor and through any sub-placement agent for settlement on such date shall be delivered by the Fund at the Distributor’s request to such sub-placement agent’s account at The Depository Trust Company through its Deposit and Withdrawal at Custodian System or by such other means of delivery as may be mutually agreed upon by the parties, against payment of the gross sales proceeds for the sale of such Shares, less the sales commission to be paid to the Distributor and such sub-placement agent.

(g) In selling Shares, the Distributor shall act solely as an agent of the Fund and not as principal.

Section 2. Representations and Warranties by the Fund. The Fund represents, warrants to and agrees with the Distributor, as of the date hereof and as of each Offering Date and Settlement Date, that:

(a) An “automatic shelf registration statement” as defined in Rule 405 under the Securities Act on Form N-2 (File No. 333-[______] and 811-21080) (the “Registration Statement”) (i) has been prepared by the Fund in conformity with the requirements of the Securities Act and the Investment Company Act in all material respects; and (ii) has been filed with the U.S. Securities and Exchange Commission (the “Commission”) under the Securities Act and the Investment Company Act; the Registration Statement sets forth the terms of the offering, sale and plan of distribution of the Shares and contains additional information concerning the Fund and its business; no notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act has been received by the Fund; the Registration Statement, including any amendments thereto, became effective upon filing; no stop order of the Commission preventing or suspending the use of the Basic Prospectus (as defined herein), the Prospectus Supplement (as defined herein) or the Prospectus (as defined herein), or the effectiveness of the Registration Statement, has been issued, and no proceedings for such purpose have been instituted or, to the Fund’s knowledge, have been threatened by the Commission. Except where the context otherwise requires, “Registration Statement,” as used herein, means, collectively, the various parts of the Registration Statement, as amended at the time of effectiveness for purposes of Section 11 of the Securities Act (the “Effective Time”), as such section applies to the Distributor, including (1) all documents filed as a part thereof or incorporated or deemed to be incorporated by reference therein, (2) any information contained or incorporated by reference in a prospectus filed with the Commission pursuant to Rule 424 under the Securities Act, to the extent such information is deemed pursuant to Rule 430B or Rule 430C under the Securities Act to be part of the Registration Statement at the Effective Time, and (3) any registration statement filed to register the offer and sale of Shares pursuant to Rule 462(b) under the Securities Act, “Basic Prospectus,” as used herein, means the final prospectus filed as part of the Registration Statement, including the related statement of additional information, together with any amendments or supplements thereto as of the date of this Agreement. Except where the context otherwise requires, “Prospectus Supplement,” as used herein, means the final prospectus supplement, including the related statement of additional information, relating to the Shares, filed by the Fund with the Commission pursuant to Rule 424 under the Securities Act, in the form furnished by the Fund to the Distributor in connection with the offering of the Shares. Except where the context otherwise requires, “Prospectus,” as used herein, means the Prospectus Supplement and the then-issued Issuer Free Writing Prospectus(es) (as defined below) together with the Basic Prospectus attached to or used with the Prospectus Supplement. “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 under the Securities Act, relating to the Shares, including without limitation any “free writing prospectus” (as defined in Rule 405 under the Securities Act) that (1) is required to be filed with the Commission by the Fund, (2) is a “road show” that is a “written communication” within the meaning of Rule 433(d)(8)(i) under the Securities Act whether or not required to be filed with the Commission, or (3) is exempt from filing pursuant to Rule 433(d)(5)(i) under the Securities Act because it contains a description of the Shares or of the offering that does not reflect the final terms, in each case in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Fund’s records pursuant to Rule 433(g) under the Securities Act. Any reference herein to the Registration Statement, the Basic Prospectus, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus shall be deemed to refer to and include the documents, if any, incorporated by reference, or deemed to be incorporated by reference, therein.

2

(b) The Fund is duly registered under the Investment Company Act as a closed-end management investment company. A notification of registration of the Fund as an investment company under the Investment Company Act on Form N-8A (the “Investment Company Act Notification”) has been prepared by the Fund in conformity with the Investment Company Act and has been filed with the Commission and, at the time of filing thereof and at the time of filing any amendment or supplement thereto, conformed in all material respects with all applicable provisions of the Investment Company Act. The Fund has not received any notice in writing from the Commission pursuant to Section 8(e) of the Investment Company Act with respect to the Investment Company Act Notification or the Registration Statement (or any amendment or supplement to either of them). No person is serving or acting as an officer, trustee or investment adviser of the Fund except in accordance with the provisions of the Investment Company Act, provided that for purposes of the foregoing representation with respect to officers and trustees, the Fund shall be entitled to rely on representations from such officers and trustees.

(c) The Registration Statement, the Investment Company Act Notification, the Prospectus and any Issuer Free Writing Prospectus, as from time to time amended or supplemented, each complied when it became effective or was filed (as the case may be), complies as of the date hereof and, as amended or supplemented, will comply, at each time of purchase of Shares in connection with each ATM offering, and at all times during which a prospectus is required by the Securities Act to be delivered in connection with any sale of Shares, in all material respects, with the requirements of the Securities Act and the Investment Company Act; the Registration Statement did not, as of the Effective Time, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; at no time during the period that begins on the earlier of the date of the Basic Prospectus and the date the Basic Prospectus was filed with the Commission and ends at the later of each time of purchase of Shares in connection with each ATM offering, and the end of the period during which a prospectus is required by the Securities Act to be delivered in connection with any sale of Shares did or will the Prospectus, as from time to time amended or supplemented, include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; each Issuer Free Writing Prospectus, as of its issue date, as of each time of purchase of Shares in connection with each ATM offering and during the period that begins on the earlier of the date of the Basic Prospectus and the date the Basic Prospectus was filed with the Commission and ends at the later of each time of purchase of Shares in connection with each ATM offering, and the end of the period during which a prospectus is required by the Securities Act to be delivered in connection with any sale of Shares, did not and will not include any information that conflicts with the information contained in the Registration Statement or the Prospectus, including any incorporated document deemed to be a part thereof that has not been superseded or modified; provided, however, that the Fund does not make any representation or warranty with respect to any statement contained in the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus in reliance upon and in conformity with information furnished in writing by the Distributor or any sub-placement agents, or on the Distributor’s or any sub-placement agent’s behalf, to the Fund expressly for use in the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus (the “Agent Provided Information”).

(d) The financial statements incorporated by reference in the Registration Statement or the Prospectus, together with the related notes and schedules, present fairly in all material respects the financial position of the Fund as of the dates indicated and the results of operations, cash flows and changes in shareholders’ equity of the Fund for the periods specified and have been prepared in compliance in all material respects with the requirements of the Securities Act, the Investment Company Act and the Exchange Act, and in conformity in all material respects with U.S. generally accepted accounting principles applied on a consistent basis during the periods involved; the other financial and statistical data contained or incorporated by reference in the Registration Statement or the Prospectus are accurately and fairly presented, in all material respects, and prepared on a basis consistent with the financial statements and books and records of the Fund in all material respects; there are no financial statements that are required to be included or incorporated by reference in the Registration Statement, the Basic Prospectus or the Prospectus by the Securities Act, the Investment Company Act or the Exchange Act that are not included or incorporated by reference as required; and the Fund does not have any material liabilities or obligations, direct or contingent (including any off-balance sheet obligations), not described in the Registration Statement (excluding the exhibits thereto).

The Fund is duly qualified to do business as a foreign entity and is in good standing in each jurisdiction where the conduct of its business requires such qualification, except where the failure to be so qualified and in good standing would not, individually or in the aggregate, have a material adverse effect on the business, properties, financial condition or results of operations of the Fund.

The Shares will be duly listed, and admitted and authorized for trading, subject to official notice of issuance, on the Stock Exchange.

(i) No approval, authorization, consent or order of or filing with any federal, state, local or foreign governmental or regulatory commission, board, body, authority or agency, or of or with any self-regulatory organization or other non-governmental regulatory authority (including, without limitation, the Stock Exchange), or approval of the shareholders of the Fund that has not already been obtained, is required in connection with the issuance and sale of the Shares or the consummation by the Fund of the transactions contemplated hereby, other than (i) the registration of the Shares under the Securities Act, which has been effected, (ii) the listing of the Shares with the Stock Exchange, upon official notice of issuance, (iii) any necessary qualification under the securities or blue sky laws of the various jurisdictions in which the Shares are being offered by the Fund or (iv) any necessary qualification pursuant to the rules of FINRA.

(b) For purposes of the ATM offering of Shares, the Fund will furnish to the Distributor and any sub-placement agents copies of its most recent amendment to its Registration Statement, its most recent Prospectus and all amendments and supplements thereto, and other documentation the Distributor may reasonably request for use in the ATM offering of Shares, including without limitation, and to the extent applicable, a No Objections Letter from FINRA, which the Fund procured. The Distributor and the sub-placement agents are authorized to furnish to prospective investors only such information concerning the Fund and the ATM offering as may be contained in the Registration Statement, the Prospectus, the Fund’s publicly available formation documents, or any other documents (including sales material), that are expressly approved by the Fund for such purpose.

Any such qualification may be withheld, terminated or withdrawn by the Fund at any time in its discretion. The expense of qualification and maintenance of qualification shall be borne by the Fund.

Section 4. Duties of the Distributor.

(a) The Distributor shall use its best efforts to perform its duties hereunder. The services of the Distributor to the Fund hereunder are not to be deemed exclusive and nothing herein contained shall prevent the Distributor from entering into like arrangements with other investment companies so long as the performance of its obligations with respect to the Fund hereunder is not impaired thereby.

(b) In performing its duties hereunder, the Distributor shall comply with the requirements of all applicable laws relating to the sale of securities in all material respects.

Such sub-placement agents shall sell Shares only at market prices subject to the Minimum Price and the Minimum Sales Price. This Agreement shall not be construed as authorizing any dealer or other person to accept orders for sale on the Fund’s behalf or to otherwise act as the Fund’s agent for any purpose. The Distributor shall not be responsible for the acts of other dealers or agents except as and to the extent that they shall be acting for the Distributor or under the Distributor’s direction or authority.

Section 8. Limitation of Liability; Indemnification.

(a) The Distributor shall not be liable for any error of judgment or mistake of law or for any loss suffered by the Fund in connection with the matters to which this Agreement relates, except a loss resulting from willful misfeasance, bad faith or gross negligence on its part in the performance of its duties or from reckless disregard by it of its obligations and duties under this Agreement. The Distributor shall not be liable for any damages arising out of any action or omission to act by any prior service provider of the Fund or for any failure to discover any such error or omission (provided that this sentence shall not apply where the Distributor was the prior service provider). Notwithstanding anything in this Agreement to the contrary, the Distributor shall not be liable for damages occurring directly or indirectly by reason of circumstances beyond its reasonable control.

(b) The Fund agrees that it will indemnify, defend and hold harmless the Distributor, its several officers, and directors, and any person who controls the Distributor within the meaning of Section 15 of the Securities Act, from and against any losses, claims, damages or liabilities, joint or several, to which the Distributor, its several officers, and directors, and any person who controls the Distributor within the meaning of Section 15 of the Securities Act, may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) (i) arise out of, or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus, or any Issuer Free Writing Prospectus or in any application or other document executed by or on behalf of the Fund or are based upon information furnished by or on behalf of the Fund filed in any state in order to qualify the Shares under the securities or blue sky laws thereof (“Blue Sky Application”) or arise out of, or are based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) arise out of, or are based upon, any breach of the representations, warranties or covenants of the Fund contained in this Agreement; provided, however, that the Fund shall not be liable in any case to the extent that such loss, claim, damage or liability arises out of, or is based upon, any untrue statement, alleged untrue statement, or omission or alleged omission made in the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or any Blue Sky Application with respect to the Fund in reliance upon and in conformity with any Agent Provided Information, or arising out of the failure of the Distributor or any sub-placement agent to deliver a current Prospectus.

7

(c) The Distributor will indemnify and hold harmless the Fund and its several officers and trustees, and any person who controls the Fund within the meaning of Section 15 of the Securities Act, from and against any losses, claims, damages or liabilities, joint or several, to which any of them may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or any Blue Sky Application, or arise out of, or are based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, which statement or omission was made in reliance upon and in conformity with information furnished in writing to the Fund or any of its several officers by or on behalf of the Distributor specifically for inclusion therein, and will reimburse the Fund and its several officers, trustees and such controlling persons for any legal or other expenses reasonably incurred by any of them in investigating, defending or preparing to defend any such action, proceeding or claim.

(d) An indemnified person under this Section 8 (the “Indemnified Party”) shall give written notice to the other party (the “Indemnifying Party”) of any loss, damage, expense, liability or claim in respect of which the Indemnifying Party has a duty to indemnify such Indemnified Party under Section 8(b) or (c) hereof (a “Claim”), specifying in reasonable detail the nature of the loss, damage, expense, liability or claim for which indemnification is sought, except that any delay or failure so to notify such Indemnifying Party shall only relieve such Indemnifying Party of its obligations hereunder to the extent, if at all, that such Indemnifying Party is actually prejudiced by reason of such delay or failure.

(e) If a Claim results from any action, suit or proceeding brought or asserted against an Indemnified Party, the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses. The Indemnified Party shall have the right to employ separate counsel in such action, suit or proceeding and participate in such defense thereof, but the fees and expenses of such separate counsel shall be at the expense of the Indemnified Party unless (i) the Indemnifying Party has agreed in writing to pay such fees and expenses, (ii) the Indemnifying Party has failed within a reasonable time to assume the defense and employ counsel or (iii) the named parties to any such action, suit or proceeding (including any impleaded parties) include both such Indemnified Party and Indemnifying Party and such Indemnified Party shall have been advised by its counsel that representation of such Indemnified Party and Indemnifying Party by the same counsel would be inappropriate under applicable standards of professional conduct (whether or not such representation by the same counsel has been proposed) due to actual or potential differing interests between the Indemnifying Party and the Indemnified Party (in which case the Indemnifying Party shall not have the right to assume the defense of such action, suit or proceeding on behalf of such Indemnified Party). It is understood, however, that the Indemnifying Party shall, in connection with any one action, suit or proceeding or separate but substantially similar or related actions, suits or proceedings in the same jurisdiction arising out of the same general allegations or circumstances be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such Indemnified Parties not having actual or potential differing interests with the Indemnifying Party or among themselves, which firm shall be designated in writing by an authorized representative of such parties and that all such fees and expenses shall be reimbursed promptly as they are incurred. The Indemnifying Party shall not be liable for any settlement of any such action, suit or proceeding effected without its written consent, but if settled with such written consent or if there be a final judgment for the plaintiff in any such action, suit or proceeding, the Indemnifying Party agrees to indemnify and hold harmless any Indemnified Party from and against any loss, liability, damage or expense by reason by such settlement or judgment.

(f) With respect to any Claim not within Section 8(e) hereof, the Indemnifying Party shall have twenty (20) days from receipt of notice from the Indemnified Party of such Claim within which to respond thereto. If the Indemnifying Party does not respond within such twenty-day period, it shall be deemed to have accepted responsibility to make payment and shall have no further right to contest the validity of such Claim. If the Indemnifying Party notifies the Indemnified Party within such twenty-day period that it rejects such Claim in whole or in part, the Indemnified Party shall be free to pursue such remedies as may be available to the Indemnified Party under applicable law.

(g) If the indemnification provided for in this Section 8 is unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, damages, expenses, liabilities or claims in such proportion as is appropriate to reflect (i) the relative benefits received by the Indemnified Party, on the one hand, and the Indemnifying Party, on the other hand, from the offering of the Shares; or (ii) if, but only if, the allocation provided for in clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Indemnified Party, on the one hand, and of the Indemnifying Party, on the other, in connection with any statements or omissions or other matters which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative fault of the parties hereto shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by such party, on one hand, or by the other party, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party hereto as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 8(g). No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(h) Notwithstanding any other provisions in this Section 8, no party shall be entitled to indemnification or contribution under this Agreement against any loss, claim, liability, expense or damage arising by reason of such person’s willful misfeasance, bad faith or gross negligence in the performance of its duties hereunder or by reason of such person’s reckless disregard of such person’s obligations and duties thereunder.

(i) The indemnity and contribution agreements contained in this Section 8 and the covenants, warranties and representations of the parties contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the Fund, its, trustees or officers or any person (including each officer or trustee of such person) who controls the Fund within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or by or on behalf of the Distributor, its directors or officers or any person who controls the Distributor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Shares.

(j) IN NO EVENT WILL ANY PARTY TO THIS AGREEMENT BE LIABLE TO ANY OTHER PERSON OR ANY THIRD PARTY FOR ANY CONSEQUENTIAL, INCIDENTAL, SPECIAL OR INDIRECT DAMAGES (INCLUDING BUT NOT LIMITED TO LOST PROFITS), EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES.

Section 9. Duration and Termination of this Agreement.

(a) This Agreement may be terminated at any time, without the payment of any penalty, by the Fund or by the Distributor, on five (5) days’ written notice to the other party.

(b) Unless earlier terminated pursuant to Section 9(a) hereof, this Agreement shall automatically terminate upon the issuance and sale of all of the Shares through the Distributor or any sub-placement agents on the terms and subject to the conditions set forth herein.

(c) This Agreement shall remain in full force and effect unless terminated pursuant to Sections (9)(a) or 9(b) hereof.

(d) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the other party. If such termination shall occur prior to the Settlement Date for any sale of Shares, such Shares shall settle in accordance with the provisions of this Agreement.

Section 10. Amendments of this Agreement. This Agreement may be amended by the parties only pursuant to a written instrument executed by the Fund and the Distributor.

Section 11. Governing Law. This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement, directly or indirectly, shall be governed by, and construed in accordance with, the internal laws of the State of New York. To the extent that the applicable law of the State of New York, or any of the provisions herein, conflict with the applicable provisions of the Investment Company Act, the latter shall control.

Section 12. Waiver of Jury Trial. EACH OF THE FUND (ON ITS BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS AFFILIATES) AND THE DISTRIBUTOR (ON ITS BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS MEMBERS AND AFFILIATES) WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) IN ANY WAY ARISING OUT OF OR RELATING TO THIS AGREEMENT.

Section 13. Miscellaneous.

(a) The captions in this Agreement are included for convenience of reference only and in no way define or delimit any of the provisions hereof or otherwise affect their construction or effect.

(b) This Agreement constitutes the entire agreement and supersedes all other prior and contemporaneous agreements and undertakings, both written and oral, among the parties hereto with regard to the subject matter hereof, including the Distribution Agreement between the parties dated March 1, 2022. If any provision of this Agreement shall be held or made invalid by a court decision, statute, rule or otherwise, the remainder of this Agreement shall not be affected thereby.

(c) This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns and the officers, and directors, trustees, and controlling persons referred to in Section 8 hereof. Neither party may assign its rights or obligations under this Agreement without the prior written consent of the other party.

(d) The parties acknowledge and agree that all share related numbers contained in this Agreement shall be adjusted to take into account any stock split, stock dividend or similar event effected with respect to the Shares.

(e) The terms “affiliated person” and “interested person,” when used in this Agreement, shall have the respective meanings specified in the Investment Company Act.

Section 14. Proprietary and Confidential Information. The Distributor agrees on behalf of itself and its employees to treat confidentially and as proprietary information of the Fund all records and other information relative to the Fund and prior, present or potential shareholders, and not to use such records and information for any purpose other than performance of its responsibilities and duties hereunder, except after prior notification to and approval in writing by the Fund, which approval shall not be unreasonably withheld and shall not be required where the Distributor may be exposed to civil or criminal contempt proceedings for failure to comply, when requested to divulge such information by duly constituted authorities, or when so requested by the Fund. The provisions of this Section 14 shall survive termination of this Agreement.

Notwithstanding anything in this Agreement to the contrary, each party hereto agrees that: (i) any Nonpublic Personal Information, as defined under Section 248.3(t) of Regulation S-P (“Regulation S-P”), promulgated under the Gramm-Leach-Bliley Act (the “Act”), disclosed by a party hereunder is for the specific purpose of permitting the other party to perform the services set forth in this Agreement, and (ii) with respect to such information, each party will comply with Regulation S-P and the Act and will not disclose any Nonpublic Personal Information received in connection with this Agreement to any other party, except to the extent as necessary to carry out the services set forth in this Agreement or as otherwise permitted by Regulation S-P or the Act.
