DISTRIBUTION AGREEMENT

This DISTRIBUTION AGREEMENT (this "Agreement") made as of December 29, 2021 by and between the RiverNorth/DoubleLine Strategic Opportunity Fund, Inc., a Maryland corporation (the "Fund"), and ALPS Distributors, Inc., a Colorado corporation (the "Distributor").

WITNESSETH:

WHEREAS, the Fund is registered under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder (collectively, 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 (File No. 333-260203 and 811-23166) (the "Registration Statement") pursuant to the Investment Company Act and the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the "Securities Act"), to register common shares of beneficial interest, $0.0001 par value, 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(a)(4) 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 a distribution agreement with each other with respect to ATM offerings, from time to time, of the Common Shares.

WHEREAS the Fund is managed by the Fund’s investment adviser, RiverNorth Capital Management, LLC (“Adviser”) and sub-advised by the Fund’s subadviser, DoubleLine Capital LP (“Subadviser”).

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 10,000,000 Common Shares of the Fund to be offered pursuant to the Registration Statement 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 (“Sub-Placement Agent Agreements”), 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 (as defined below) 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 second business day following the date on which such sales are made (each such day, a "Settlement Date"). 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)       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; (ii) has been filed with the U.S. Securities and Exchange Commission (the "Commission") under the Securities Act and the Investment Company Act; and (iii) heretofore became, and is, effective; 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 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.

(e)       As of the date of this Agreement, the Fund has an authorized and outstanding capitalization as set forth in the Registration Statement, the Basic Prospectus and the Prospectus and, with respect to any issuance and sale under this Agreement, the Fund shall have as of the date of the most recent amendment or supplement to the Registration Statement or Prospectus, an authorized and outstanding capitalization as set forth in the Registration Statement and the Prospectus; all of the issued and outstanding Common Shares have been duly authorized and validly issued and are fully paid and non-assessable, have been issued in material compliance with all applicable securities laws and were not issued in violation of any preemptive right, resale right, right of first refusal or similar right.

(f)       The Fund has been duly formed, has legal existence as a corporation and is in good standing under the laws of Maryland, with full power and authority to own, lease and operate and conduct its business as described in the Registration Statement, the Basic Prospectus and the Prospectus and to issue, sell and deliver the Shares as contemplated herein. 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.

Section 3. Duties of the Fund.

(a)       The Fund shall take, from time to time, but subject always to any necessary approval of the Board or of its shareholders, all necessary action to fix the number of authorized Common Shares, to the end that the Fund will have a number of authorized but unissued Common Shares at least equal to the number of Common Shares available for sale pursuant to this Agreement.

(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. 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.

(c)       The Fund shall furnish to the Distributor copies of all financial statements of the Fund which the Distributor may reasonably request for use in connection with its duties hereunder, and this shall include, upon request by the Distributor, one certified copy of all financial statements prepared for the Fund by independent public accountants.

(d)       The Fund shall use its best efforts to qualify and maintain, to the extent required by applicable law, the qualification of Shares for sale under the securities laws of such jurisdictions as the Distributor and the Fund may approve, provided that the Fund shall not be required in connection therewith to qualify as a foreign corporation or dealer in securities or to file a general consent to service of process in any jurisdiction or meet any other requirement in connection with this Section 3(d) deemed by the Fund to be unduly burdensome. 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. The Distributor shall furnish such information and other material relating to its affairs and activities as may be required by the Fund in connection with such qualification.

(e)       The Fund will furnish, in reasonable quantities upon request by the Distributor, copies of its annual and semi-annual reports.

(f)       The Fund will furnish the Distributor with such other documents as it may reasonably require, from time to time, for the purpose of enabling it to perform its duties as contemplated by this Agreement.

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. Neither the Distributor nor any sub-placement agent having an agreement to offer and sell Shares pursuant to Section 5 hereof nor any other person is authorized by the Fund to give any information or to make any representations, other than those contained in its Registration Statement, Prospectus and any sales literature specifically approved for such use by the Fund.

(c)       The Distributor shall review and file with FINRA as applicable, all sales literature (advertisements, brochures and shareholder communications) prepared in connection with the ATM offerings for the Fund.

(d)       The Distributor agrees to supply the following additional services, either on its own or in conjunction with the Fund’s other service providers, including but not limited to the Adviser or Subadviser, together with such other services as set forth throughout this Agreement:

For the avoidance of doubt, the Distributor shall not sell any shares of the Fund directly to any investors.

(e)       The Distributor shall report to the Board at least quarterly, or more frequently, as requested by the Board, regarding: (i) the nature of the services provided by the Distributor hereunder; (ii) the amount of compensation sub-placement agents, if any, are entitled to retain or be paid by the Distributor; and (iii) the aggregate amount of underwriting compensation paid by the Fund to the Distributor in respect of the ATM offerings of Shares.

(f)       The Distributor represents and warrants to the Fund that it has all necessary licenses to perform the services contemplated hereunder and will perform such services in compliance with all applicable rules and regulations.

Section 5. Agreements with Sub-Placement Agents.

(a)       The Distributor may enter into Sub-Placement Agent Agreements, on such terms and conditions as the Distributor determines are not inconsistent with this Agreement, with sub-placement agents to act as the Distributor's agents to effect the sale of the Shares in the ATM offerings. 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.

(b)       The Distributor shall offer and sell Shares only through such sub-placement agents who are acting as brokers or dealers who are registered as broker-dealers under the provisions of the Exchange Act and members in good standing of FINRA and who agree to abide by the rules of FINRA.

(c)       The Distributor shall obtain assurance, reasonably satisfactory to the Fund, from any sub-placement agents which it engages of the compliance by such sub-placement agents with the terms of this Agreement, applicable federal and state securities laws and the rules of FINRA.

Section 6. Sales Commission; Compensation.

(a)       The Fund shall pay the Distributor an amount equal to 1.00% of the gross sales price per Share of the Shares sold.

(b)       The Distributor shall pay to the sub-placement agents the sub-placement agent commissions agreed to between the Distributor and such sub-placement agents, or may authorize such sub-placement agents to retain such sub-placement agent commissions from the gross sales proceeds from the sale of such Shares, which shall be payable from the commissions payable to the Distributor under Section 6(a) hereof.

(c)       The Fund hereby represents and warrants to the Distributor that (i) the terms of this Agreement, (ii) the fees and expenses associated with this Agreement, and (iii) any benefits accruing to the Distributor or to the Adviser, the Subadviser or sponsor or another affiliate of the Fund in connection with this Agreement, which the Fund has agreed to pay, including but not limited to any fee waivers, conversion cost reimbursements, up-front payments, signing payments or periodic payments relating to this Agreement have been fully disclosed to the Board and that, if required by applicable law, the Board has approved or will approve the terms of this Agreement, any such fees and expenses, and any such benefits.

Section 7. Payment of Expenses.

(a)       The Fund shall bear all of its own costs and expenses, including fees and disbursements of its counsel and auditors, in connection with the preparation of its Prospectus, Statement of Additional Information, if any, the preparation and filing of any required registration statements under the Securities Act and/or the Investment Company Act, and all amendments and supplements thereto, and in connection with any fees and expenses incurred with respect to any filing requirements of FINRA and preparing and mailing annual and interim reports and proxy materials to shareholders (including but not limited to the expense of setting in type any such Registration Statement, Prospectus, interim reports or proxy materials).

(b)       The Fund shall bear any cost and expenses of qualification of the Shares for sale pursuant to this Agreement.

(c)       The Distributor shall bear all expenses incurred by it in connection with its duties and activities under this Agreement, including the compensation of sub-placement agents for sales of the Fund's Shares, provided that it shall pay such sub-placement agents only for so long as and to the extent that it receives such compensation from the Fund, and fees and expenses of Distributor's counsel (except for any FINRA filing fees or "blue sky" fees paid on behalf of the Fund or the Distributor by such counsel).

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 Prospectuses 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 or any Blue Sky Application with respect to the Fund in reliance upon and in conformity with any information furnished in writing by the Distributor, or on the Distributor's behalf, to the Fund expressly for use in the Registration Statement or the Prospectus, or arising out of the failure of the Distributor to deliver a current Prospectus.

(c)       The Distributor will indemnify and hold harmless the Fund and its several officers and Directors, 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 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, Directors 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)       At the request and direction of the Fund, the Distributor enters into Sub-Placement Agent Agreements. The Distributor will not be obligated to make payments to any such Sub-Placement Agent unless the Distributor has received an authorized payment from the Fund. In addition, to the extent that the Distributor is requested or required by the Fund to enter into Sub-Placement Agent Agreements, the Distributor and each of its affiliates, members, shareholders, directors, officers, partners, employees, agents, successors or assigns (“Distributor Associates”) shall not be liable to the Fund for any action or inaction of any Distributor Associate except to the extent of direct Losses¹ finally determined by a court of competent jurisdiction to have resulted solely from the gross negligence, willful misconduct or fraud of the Distributor in the performance of the Distributor’s duties, obligations, representations, warranties or indemnities under a Sub-Placement Agent Agreement. Under no circumstances shall Distributor Associates be liable for Losses that are indirect, special, incidental, consequential, punitive, exemplary or enhanced or that represent lost profits, opportunity costs or diminution of value. The Fund shall indemnify, defend and hold harmless Distributor Associates from and against Losses (including legal fees and costs to enforce this provision) that Distributor Associates suffer, incur, or pay as a result of any third-party claim or claim among the parties arising out of the subject matter of or otherwise in any way related to a Sub-Placement Agent Agreement (“Claims”). Any expenses (including legal fees and costs) incurred by Distributor Associates in defending or responding to any Claims (or in enforcing this provision) shall be paid by the Fund on a quarterly basis prior to the final disposition of such matter upon receipt by the Fund of an undertaking by the Distributor to repay such amount if it shall be determined that a Distributor Associate is not entitled to be indemnified. Notwithstanding the foregoing, nothing contained in this paragraph or elsewhere in this Agreement shall constitute a waiver by the Fund of any of its legal rights available under U.S. federal securities laws or any other laws whose applicability is not permitted to be contractually waived.

(e)       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.

(f)       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.

(g)       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.

(h)       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.

(j)       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, Directors or officers or any person (including each officer or Director 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.

(k)       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.

(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.

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.

SUB-PLACEMENT AGENT AGREEMENT
ALPS Distributors, Inc.

1290 Broadway, Suite 1000

Denver, CO 80203

December 29, 2021

UBS Securities LLC
1285 Avenue of the Americas
New York, New York 10019

Ladies and Gentlemen:

From time to time ALPS Distributors, Inc. (the "Distributor", "we" or "us") will act as manager of registered at-the-market offerings by RiverNorth/DoubleLine Strategic Opportunity Fund, Inc., a Maryland corporation (the "Fund"), of up to 10,000,000 shares (the "Shares") of beneficial interest, $0.0001 par value, of the Fund (the "Common Shares"). In the case of such offerings, the Fund has agreed with the Distributor to issue and sell through the Distributor, as sales agent, the Shares (the "Distribution Agreement").

We hereby agree to retain UBS Securities LLC (the "Agent" or "you") as a sub-placement agent with respect to the offerings of the Shares to be issued and sold by the Fund (the "Offerings") as the Fund and the Distributor may indicate from time to time, and you agree to act in such capacity, all upon, and subject to, the terms and conditions set forth below:

SECTION 1. Description of Offerings.

(a)       The Shares are to be sold on a daily basis or otherwise as shall be determined by the Fund together with the Distributor or the Agent on any day (each, an "Offering Date") that is a trading day for the exchange on which the Fund's Shares are listed and primarily trade (the "Stock Exchange") (other than a day on which the Stock Exchange is scheduled to close prior to its regular weekday closing time). Promptly after the Fund together with the Distributor or the Agent have determined the maximum amount of the Shares to be distributed by the Distributor for any Offering Date, which shall not in any event exceed the amount available for issuance under the currently effective Registration Statement (as defined herein) (the "Maximum Daily Amount"), and the minimum price per Share below which the Shares may not be sold by the Agent on any Offering Date (the "Minimum Daily Price"), the Distributor and/or the Fund’s investment adviser, RiverNorth Capital Management, LLC, or subadviser, DoubleLine Capital LP, shall advise the Agent of the Maximum Daily Amount and the Minimum Daily Price. Subject to the terms and conditions hereof, the Agent shall use its reasonable best efforts to sell all of the Shares designated in accordance with the plan of distribution set forth in the Prospectus Supplement (as defined herein); provided, however, that in no event shall the Agent sell Shares in excess of the Maximum Daily Amount or for a price per Share below the Minimum Daily Price. The gross sales price of the Shares sold under this Section 1(a) shall be the market price at which the Agent sells such Shares.

(b)       Notwithstanding the foregoing, the Distributor or the Fund may instruct the Agent by telephone (confirmed promptly by e-mail or other electronic means) of a revised Minimum Daily Price and/or a revised Maximum Daily Amount and the Agent shall not sell Shares for a price per Share below such revised Minimum Daily Price, or in a quantity in excess of such revised Maximum Daily Amount, after the giving of such notice. In addition, the Distributor or the Fund may, upon notice to the Agent by telephone (confirmed promptly by e-mail or other electronic means), suspend the offering of the Shares at any time; 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.

(c)       The Agent agrees not to make any sales of the Shares pursuant to this Section 1, other than through transactions for which compliance with Rule 153 under the Securities Act of 1933, as amended (the "Securities Act"), will satisfy the prospectus delivery requirements of Section 5(b)(2) of the Securities Act.

(d)       The compensation to the Agent, as a sub-placement agent for each sale of the Shares pursuant to this Section 1, shall be the Applicable Selling Agent Commission (as set forth on the Addendum hereto) with respect to the Shares sold, multiplied by the Gross Sales Proceeds (as defined in the Addendum attached hereto) (the "Agent Compensation"), as further described in the Addendum to this Sub-Placement Agent Agreement (the "Agreement"). The Agent shall not be responsible for any fees imposed by any governmental or self-regulatory organization on the Fund or the Distributor in respect of such sales. The Distributor may pay the Agent Compensation to the Agent, or may authorize the Agent to retain the Agent Compensation from the Gross Sales Proceeds. The Agent Compensation shall be payable solely out of the compensation the Distributor receives from the Fund pursuant to the Distribution Agreement (the "Related Compensation"). Notwithstanding anything to the contrary in any other provision of this Agreement (or, for the avoidance of doubt, in the Addendum hereto), the Distributor shall have no obligation to pay any portion of the Agent Compensation to the Agent, or authorize the retention by the Agent of any portion of the Agent Compensation from the Gross Sales Proceeds, until the Distributor receives at least an equivalent amount of Related Compensation, and the Distributor's obligation to the Agent for the Agent Compensation is limited solely to amounts payable out of the Related Compensation.

(e)       The Agent shall provide written confirmation to the Distributor following the close of trading on the Stock Exchange on each Offering Date setting forth for each sale the number of Shares sold, the time of sale, the Gross Sales Price (as defined in the Addendum attached hereto) per Share, and the compensation that the Agent is owed with respect to such sales.

(f)       Settlement for sales of the Shares pursuant to this Section 1 will occur on the second business day following the date on which such sales are made (each such day, a "Settlement Date"). On each Settlement Date, the Shares sold through the Agent for settlement on such date shall be delivered by the Fund at the request of the Distributor to the Agent against payment of (i) the Gross Sales Proceeds for the sale of such Shares or (ii) to the extent authorized by the Distributor, the Gross Sales Proceeds, less the Related Compensation. If the Agent is authorized by the Distributor to retain the Agent Compensation from the Gross Sales Proceeds for the sale of the Shares, then the Agent shall (i) pay to the Distributor an amount equal to the Related Compensation minus the Agent Compensation in same day funds delivered to the account(s) designated by the Distributor and (ii) remit to the Fund the Gross Sales Proceeds, less the Related Compensation. If the Distributor shall default on its obligation to deliver the Shares on any Settlement Date, subject to the terms of Section 5 herein, the Distributor shall (A) hold the Agent harmless against any reasonable loss, claim or damage arising from or as a result of such default by the Distributor and (B) pay the Agent any commission to which it would otherwise be entitled absent such default. If the Agent breaches this Agreement by failing to deliver proceeds on any Settlement Date for the Shares delivered by the Distributor, subject to the terms of Section 5 herein, the Agent shall (A) hold the Distributor harmless against any reasonable loss, claim or damage arising from or as a result of such default by the Agent, (B) deliver such proceeds to the Distributor as soon as practicable and (C) pay the Distributor interest based on the effective overnight Federal Funds rate.

(g)       In connection with this Agreement and the Offerings, the Distributor shall, no more than once per calendar quarter in which the Fund and the Distributor have requested, or anticipate requesting, that the Agent sell Shares pursuant to an Offering, provide to the Agent such certificates and other documents, in any case, as the Agent may reasonably request upon reasonable notice (but in no event upon notice of less than five business days) relating to authorization, capacity, enforceability and compliance matters. Any such certifications shall be made as of the end of the calendar quarter immediately preceding the calendar quarter in which such request by the Agent is made.

(h)       In connection with this Agreement and the Offerings, the Agent will promptly notify the Distributor of any material non-confidential claim or complaint, any material enforcement action or other material proceeding by a regulatory authority with respect to the Fund, the Shares or the Offerings against or directed at or to the Agent or its principals, affiliates, officers, directors, employees or agents, or any person who controls the Agent, within the meaning of Section 15 of the Securities Act.

(i)       In connection with this Agreement and the Offerings, the Agent will promptly notify the Distributor of any examination by any regulatory agency or self-regulatory organization that has resulted in a material compliance deficiency in connection with the Offerings.

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, and (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 to be part of the registration statement at the Effective Time.

This Agreement has been duly authorized, executed and delivered by the Agent. Assuming due authorization, execution and delivery by the Distributor, this Agreement constitutes a valid and binding agreement of the Agent and is enforceable against the Agent in accordance with its terms, except as the enforceability hereof and thereof may be limited by applicable bankruptcy, insolvency, reorganization and similar laws affecting creditors' rights generally and moratorium laws in effect from time to time and by equitable principles restricting the availability of equitable remedies.

(a)       The Agent hereby confirms that it is actually engaged in the investment banking and securities business and is a member in good standing with FINRA and hereby agrees that it will undertake to comply with all applicable FINRA rules (as amended from time to time, including without limitation, any successor provision) in connection with acting as sub-placement agent for the sale of the Shares. The Agent further agrees that in acting as sub-placement agent for the sale of the Shares, it will comply with all applicable laws, rules and regulations, including the applicable provisions of the Securities Act and the Exchange Act, the applicable rules and regulations of the Commission thereunder, and the applicable rules and regulations of any state or any securities exchange or self-regulatory organization having jurisdiction over the relevant Offering.

(b)       The Agent hereby agrees that in acting as sub-placement agent for the sale of the Shares, it will not use, authorize use of, refer to, or participate in the planning for use of any written communication (as defined in Rule 405 under the Securities Act) concerning any Offering, other than the Prospectus. The Agent further agrees that in acting as sub-placement agent for the sale of the Shares, it is not authorized by the Distributor or the Fund or any other seller of the Shares offered pursuant to the Prospectus to give any information or to make any representation not contained in the Prospectus in connection with the sale of such Shares.

(c)       The Distributor shall not be under any obligation to the Agent except for obligations assumed hereunder or in writing by the Distributor in connection with any Offering. Nothing contained herein or in any communication in writing from us shall constitute the Distributor and the Agent an association or partners with one another. If such parties should be deemed to constitute a partnership for Federal income tax purposes, then the Agent elects to be excluded from the application of Subchapter K, Chapter 1, Subtitle A of the Internal Revenue Code of 1986 and agrees not to take any position inconsistent with that election. The Agent authorizes the Distributor, in its discretion, to execute and file on its behalf such evidence of that election as may be required by the Internal Revenue Service. In connection with any Offering, each party shall be liable for its proportionate amount of any tax, claim, demand or liability that may be asserted against it alone, based upon the claim that either of them constitutes an association, an unincorporated business or other entity, including, in each case, its proportionate amount of any expense incurred in defending against any such tax, claim, demand or liability.

(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 effected with respect to the Shares.

(e)       The Agent shall at all times comply with the offering requirements as set forth herein and under the heading "Plan of Distribution" in the Prospectus.

SECTION 5. Indemnification and Contribution.

(a)       The Distributor agrees to indemnify, defend and hold harmless the Agent, its partners, directors and officers, and any person who controls the Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any reasonable loss, damage, expense, liability or claim (including the reasonable cost of investigation) which the Agent or any such person may incur under the Securities Act, the 1940 Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim (or any actions or proceedings in respect thereof) arises out of or is based upon (i) any material breach of any representation, warranty, covenant or agreement of the Distributor contained in this Agreement, (ii) any material violation by the Distributor of any law, rule or regulation (including any rule of any self-regulatory organization) applicable to the Offerings, or (iii) any untrue statement or alleged untrue statement of a material fact appearing in the Registration Statement or Prospectus or omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading, except to the extent such statements were included in the Registration Statement or Prospectus in reliance upon and in conformity with the Agent Provided Information.

(b)       The Agent agrees to indemnify, defend and hold harmless the Distributor, the Fund, their partners, directors and officers, and any person who controls the Distributor or the Fund within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which the Distributor, the Fund or any such other person may incur under the Securities Act, the 1940 Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim (or any actions or proceedings in respect thereof) arises out of or is based upon (i) any material breach of any representation, warranty, covenant or agreement of the Agent contained in this Agreement or (ii) any material violation by the Agent of any law, rule or regulation (including any rule of any self-regulatory organization), or (iii) any untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement or the Prospectus in reliance upon and in conformity with the Agent Provided Information.

(c)       An indemnified person under Section 5 of this Agreement (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 5(a) or (b) of this Agreement (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.

(d)       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.

(e)       With respect to any Claim not within Paragraph (d) of Section 5 hereof, the Indemnifying Party shall have 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.

(f)       If the indemnification provided for in this Section 5 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 benefits received by the Distributor, on the one hand, and the Agent, on the other, shall be deemed to be in the same respective proportions as the total compensation received by the Distributor from sales of the Shares bears to the total compensation received by the Agent from sales of the Shares. 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 5 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 subsection (f). 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. Notwithstanding the foregoing provisions of this subsection (f), the Agent shall not be required to contribute any amount in excess of the commissions received by it under this Agreement.

(g)       The indemnity and contribution agreements contained in this Section 5 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 Agent, its partners, directors or officers or any person (including each partner, officer or director of such person) who controls the Agent 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.

(h)       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 6. Termination.

(a)       This Agreement shall continue in full force and effect until terminated by either party, including by written instruction by the Fund to the Distributor, by five days' written notice to the other party; provided, that if this Agreement has become effective with respect to any Offering pursuant to this Agreement, this Agreement may not be terminated by either party with respect to such Offering.

(b)       This Agreement shall remain in full force and effect unless terminated pursuant to Section 6(a) hereof or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement shall in all cases be deemed to provide that Section 5 shall remain in full force and effect.

(c)       Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that in any event such termination shall not be effective until any earlier than the close of business on the fifth day after receipt of such notice by the Distributor or the Agent, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of the Shares, such sale shall settle in accordance with the provisions of Section 1 of this Agreement.

SECTION 7. Notices. Except as otherwise herein provided, all statements, requests, notices and agreements under this Agreement shall be in and delivered by hand, overnight courier, mail or email and shall be sufficient in all respects if delivered or sent to:
