Item 30. Indemnification

Our charter, as amended, provides for indemnification for persons who are or were a director, officer or employee of CSWC or CSMC against any and all judgments, penalties (including excise and similar taxes), fines, settlements and reasonable expenses actually incurred by such person in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative or investigative, any appeal in such action, suit or proceeding, and any inquiry or investigation that could lead to such action, suit or proceeding, on account of such person’s service as a director officer or employee of CSWC or CSMC, or service at the request of CSWC or CSMC as a director, officer, partner, venturer, proprietor, trustee, employee, agent or similar functionary of another foreign or domestic corporation, partnership, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise all to the fullest extent permitted by Texas law. The charter provides that we must not provide indemnification to the extent not prohibited by the 1940 Act. In accordance with the 1940 Act, the Registrant will not indemnify any person for any liability to which such person would be subject by reason of such person’s willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office.

Texas law requires a corporation to indemnify a director or officer against reasonable expenses actually incurred by him or her in connection with a threatened, pending, or completed action or other proceeding in which he or she is a named defendant or respondent because he or she is or was a director or officer if he or she has been wholly successful, on the merits or otherwise, in the defense of the action or proceeding. Texas law permits a corporation to indemnify a director or former director against judgments and expenses reasonably and actually incurred by the person in connection with a proceeding if the person (i) acted in good faith, (ii) reasonably believed, in the case of conduct in the person’s official capacity, that the person’s conduct was in the corporation’s best interests, and otherwise, that the person’s conduct was not opposed to the corporation’s best interests, and (iii) in the case of a criminal proceeding, did not have a reasonable cause to believe the person’s conduct was unlawful. If, however, the person is found liable to the corporation, or is found liable on the basis that such person received an improper personal benefit, then indemnification under Texas law is limited to the reimbursement of reasonable expenses actually incurred, and no indemnification will be available if the person is found liable for (i) willful or intentional misconduct in the performance of the person’s duty to the corporation, (ii) breach of the person’s duty of loyalty owed to the corporation, or (iii) an act or omission not committed in good faith that constitutes a breach of a duty owed by the person to the corporation. In addition, Texas law permits a corporation to advance reasonable expenses to a director or officer upon the corporation’s receipt of (a) a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation and (b) a written undertaking by him or her or on his or her behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the standard of conduct was not met.

C-5

Our charter authorizes us to purchase or maintain insurance against any liability asserted against a director, officer or employee of the Company. We have obtained primary and excess insurance policies insuring our directors and officers against certain liabilities they may incur in their capacity as directors and officers. Under such policies, the insurer, on our behalf, may also pay amounts for which we have granted indemnification to the directors or officers.

Ladies and Gentlemen:

Capital Southwest Corporation, a Texas corporation (the “Company”), proposes to issue and sell a minimum of 0 shares and a maximum of 600,000 shares of the Company’s common stock, par value $0.25 per share (“Common Stock”) and Sanders Morris Harris LLC, a Texas limited liability company (the “Underwriter”), proposes to sell on a “best efforts” basis an aggregate of up to 600,000 shares of Common Stock (collectively, the “Shares”) to investors deemed acceptable by the Company (the “Investors”) in a public offering pursuant to the Securities Act of 1933, as amended. The Underwriter has agreed to act, on a best efforts basis only, as the Underwriter in connection with the offering and sale of the Shares (the “Offering”).

The Company confirms its agreement with the Underwriter as follows:

SECTION 1. Agreement to Act on a Best Efforts Basis. On the basis of the representations, warranties and agreements of the Company herein contained and subject to all the terms and conditions of this Agreement, the Underwriter agrees to act on a best efforts, min/max basis only, in connection with the issuance and sale by the Company of the Shares to the Investors. Under no circumstances will the Underwriter be obligated to underwrite or purchase any of the Shares for their respective accounts or otherwise provide any financing. Upon the Closing (as defined below) of the Offering, the Underwriter shall purchase the Shares, if any, from the Company at a price of $18.90 per Share (the “Company Price”) and the Underwriter shall sell the Shares to Investors at a price of $19.26 per Share (the “Investor Price”). The difference between the Investor Price and the Company Price of $0.36 per Share shall be considered the Underwriter’s Discount.

SECTION 2. Delivery and Payment. The Offering shall close on October 4, 2018 (the “Closing Date”) at 10 a.m., CDT. On the Closing Date, the Underwriter shall deliver, in immediately available funds, an amount equal to $18.90 per share, multiplied by the number of Shares sold in the “best efforts” offering to the Company, up to an aggregate amount of 600,000 Shares.

SECTION 3. Representations and Warranties of the Company.

The Company represents, warrants and covenants to the Underwriter as follows:

(a) The Company has filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the “Securities Act”), with the Securities and Exchange Commission (the “Commission”) a registration statement on Form N-2 (File No. 333-220385), including a base prospectus, relating to the Common Stock, including the Shares to be issued by the Company. The Company has prepared a prospectus supplement specifically relating to the Shares (the “Prospectus Supplement”) to the base prospectus included as part of such registration statement. The Company will furnish to Underwriter, for use by the Underwriter, copies

1

of the prospectus included as part of such registration statement, as supplemented by the Prospectus Supplement, relating to the Shares. Except where the context otherwise requires, such registration statement, as amended when it became effective, including all documents filed as part thereof, and including any information contained in a Prospectus (as defined below) subsequently filed with the Commission pursuant to Rule 497 under the Securities Act or deemed to be a part of such registration statement pursuant to Rule 430C of the Securities Act, is herein called the “Registration Statement.” The base prospectus, included in the Registration Statement, as it may be supplemented by the Prospectus Supplement, in the form in which such prospectus and/or Prospectus Supplement have most recently been filed by the Company with the Commission pursuant to Rule 497 under the Securities Act is herein called the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement and the Prospectus shall be deemed to include any amendment or supplement thereto that has been filed with the Commission pursuant to EDGAR. (b) The Registration Statement has been filed with the Commission in accordance with the Securities Act; no stop order of the Commission preventing or suspending the qualification or use of the Prospectus, or any amendment thereto, has been issued, and no proceedings for such purpose have been instituted, or, to the Company’s knowledge, are contemplated by the Commission.

(c) The Registration Statement, at the time it became effective, conformed in all material respects to the requirements of the Securities Act.

(d) The Registration Statement, at the time it became effective, did not 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.

(e) The Prospectus did not, as of its date, 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, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representation or warranty with respect to the statements contained therein as provided by the Underwriter in Section 8(c).

(f) As of the date hereof, the Company is duly organized and validly existing as a corporation in good standing under the laws of the State of Texas. The Company has full power and authority to conduct all the activities conducted by it, to own and lease all the assets owned and leased by it and to conduct its business as presently conducted and as described in the Prospectus Statement and the Prospectus. The Company is duly licensed or qualified to do business and in good standing as a foreign organization in all jurisdictions in which the nature of the activities conducted by it or the character of the assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so qualified or in good standing or have such power or authority would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on or affecting the business, prospects, properties, management, financial position, stockholders’ equity, or results of operations of the Company and its Subsidiaries taken as a whole (a “Material Adverse Effect”). Complete and correct copies of the certificate of incorporation and of the bylaws of the Company and all amendments thereto have been made available to the Underwriter, and no changes therein will be made subsequent to the date hereof and prior to the Closing Date.

(g) The Company has no subsidiaries, nor does it own a controlling interest in any entity other than those entities set forth on under Item 28 of the Registration Statement (each a “Subsidiary” and collectively the “Subsidiaries”). Each Subsidiary has been duly organized and is validly existing and in good standing under the laws of its jurisdiction of formation. Each Subsidiary is duly qualified and in good standing as a foreign company in each jurisdiction in which the character or location of its properties (owned, leased or licensed) or the nature or conduct of its business makes such qualification necessary, except for those failures to be so qualified or in good standing

2

which would not be reasonably expected to have a Material Adverse Effect. All of the shares of issued capital stock of each corporate subsidiary, and all of the share capital, membership interests and/or equity interests of each subsidiary that is not a corporation, have been duly authorized and validly issued, are fully paid and non-assessable and are owned directly or indirectly by the Company, free and clear of any lien, encumbrance, claim, security interest, restriction on transfer, shareholders’ agreement, proxy, voting trust or other defect of title whatsoever.

(h) The Company is organized in, and its principal place of business is in, the United States.

(i) The Company is a closed-end, non-diversified management investment company and has duly filed a notification on Form N-54A of election to be regulated as a BDC (the “1940 Act Notification”) under the Investment Company Act of 1940, as amended (the “1940 Act”), with the Commission and is eligible to make such an election. The Company has not filed with the Commission any notice of withdrawal of the 1940 Act Notification pursuant to Section 54(c) of the 1940 Act; the 1940 Act Notification remains in full force and effect, and, to the Company’s knowledge, no order of suspension or revocation of such election under the 1940 Act has been issued or proceedings therefore initiated or threatened by the Commission. The operations of the Company are in compliance in all material respects with the applicable provisions of the 1940 Act and the rules and regulations thereunder.

(j) The Company is not a “foreign private issuer,” as such term is defined in Rule 405 under the Securities Act.

(k) The Company has full legal right, power and authority to enter into this Agreement and perform the transactions contemplated hereby and thereby. This Agreement has been authorized and validly executed and delivered by the Company and is a legal, valid and binding agreement of the Company enforceable against the Company in accordance with its terms, subject to the effect of applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally and equitable principles of general applicability.

The holders of the Shares will not be subject to personal liability by reason of being such holders. The Shares, when issued, will conform to the description thereof set forth in the Prospectus in all material respects.

(m) The financial statements and the related notes included in the Prospectus present fairly, in all material respects, the financial condition of the Company and its Subsidiaries as of the dates thereof and the results of operations and cash flows at the dates and for the periods covered thereby in conformity with United States generally accepted accounting principles (“GAAP”), except as may be stated in the related notes thereto.

The Company shall indemnify and hold harmless the Underwriter, its affiliates and its directors, officers, members, employees and agents and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Securities Act of or Section 20 of the Exchange Act (collectively the “Underwriter Indemnified Parties,” and each a “Underwriter Indemnified Party”) against any loss, claim, damage, expense or liability whatsoever (or any action, investigation or proceeding in respect thereof), to which such Underwriter Indemnified Party may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, expense, liability, action, investigation or proceeding arises out of or is based upon (A) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus or any amendment or supplement thereto, (B) the omission or alleged omission to state in the Registration Statement or the Prospectus, or in any amendment or supplement thereto, a material fact required to be stated therein or necessary to make the statements therein not misleading or (C) any breach of the representations and warranties of the Company contained herein or failure of the Company to perform its obligations hereunder or pursuant to any law, any act or failure to act, or any alleged act or failure to act, by the Underwriter in connection with, or relating in any manner to, this Agreement, the Shares or this offering, and which is included as part of or referred to in any loss, claim, damage, expense, liability, action, investigation or proceeding arising out of or based upon matters covered by subclause (A), (B) or (C) above of this Section 8(a) (provided that the Company shall not be liable in the case of any matter covered by this subclause (C) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, expense or liability resulted directly from any such act or failure to act undertaken or omitted to be taken by the Underwriter through its gross negligence or willful misconduct), and shall reimburse the Underwriter Indemnified Party promptly upon demand for any legal fees or other expenses reasonably incurred by that Underwriter Indemnified Party in connection with investigating, or preparing to defend, or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding, as such fees and expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, expense or liability arises out of or is based upon an untrue statement in, or omission from the Registration Statement or the Prospectus, or any such amendment or supplement

13

thereto, made in reliance upon and in conformity with written information furnished to the Company, if any, by or through the Underwriter expressly for use therein. This indemnity agreement is not exclusive and will be in addition to any liability, which the Company might otherwise have and shall not limit any rights or remedies which may otherwise be available at law or in equity to each Underwriter Indemnified Party.

(b) Indemnification by the Underwriter. The Underwriter shall indemnify and hold harmless the Company and the Company’s directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively the “Company Indemnified Parties” and each a “Company Indemnified Party”) against any loss, claim, damage, expense or liability whatsoever (or any action, investigation or proceeding in respect thereof), to which such Company Indemnified Party may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, expense, liability, action, investigation or proceeding arises out of or is based upon (i) any untrue statement of a material fact contained in the Registration Statement or the Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use, or (ii) the omission to state in the Registration Statement or the Prospectus, or any amendment or supplement thereto, a material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or omission was made in reliance upon and in conformity with written information furnished to the Company, if any, by or through the Underwriter expressly for use therein, and shall reimburse the Company for any legal or other expenses reasonably incurred by such party in connection with investigating or preparing to defend or defending against or appearing as third party witness in connection with any such loss, claim, damage, liability, action, investigation or proceeding, as such fees and expenses are incurred.

(c) Procedure. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify such indemnifying party in writing of the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially adversely prejudiced by such failure; and, provided, further, that the failure to notify an indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense of such action with counsel reasonably satisfactory to the indemnified party (which counsel shall not, except with the written consent of the indemnified party, be counsel to the indemnifying party). After notice from the indemnifying party to the indemnified party of its election to assume the defense of such action, except as provided herein, the indemnifying party shall not be liable to the indemnified party under Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense of such action other than reasonable costs of investigation; provided, however, that any indemnified party shall have the right to employ separate counsel in any such action and to participate in the defense of such action but the fees and expenses of such counsel (other than reasonable costs of investigation) shall be at the expense of such indemnified party unless (i) the employment thereof has been specifically authorized in writing by the Company in the case of a claim for indemnification under 8(a), (ii) such indemnified party shall have been advised by its counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party has failed to assume the defense of such action and employ counsel reasonably

14

satisfactory to the indemnified party within a reasonable period of time after notice of the commencement of the action or the indemnifying party does not diligently defend the action after assumption of the defense, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of (or, in the case of a failure to diligently defend the action after assumption of the defense, to continue to defend) such action on behalf of such indemnified party and the indemnifying party shall be responsible for legal or other expenses subsequently incurred by such indemnified party in connection with the defense of such action; provided, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any time any such indemnified party (in addition to any local counsel), which firm shall be designated in writing by the Underwriter if the indemnified party under this Section 8 is an Underwriter Indemnified Party, by the Company if an indemnified party under this Section 8 is a Company Indemnified Party. Subject to this Section 8, the amount payable by an indemnifying party under Section 8 shall include, but not be limited to, (x) reasonable legal fees and expenses of counsel to the indemnified party and any other expenses in investigating, or preparing to defend or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection with, any action, investigation, proceeding or claim, and (y) all amounts paid in settlement of any of the foregoing. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of judgment with respect to any pending or threatened action or any claim whatsoever, in respect of which indemnification or contribution could be sought under this Section 8 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party in form and substance reasonably satisfactory to such indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. Subject to the provisions of the following sentence, no indemnifying party shall be liable for settlement of any pending or threatened action or any claim whatsoever that is effected without its written consent (which consent shall not be unreasonably withheld or delayed), but if settled with its written consent, if its consent has been unreasonably withheld or delayed or if there be a judgment for the plaintiff in any such matter, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, if at any time an indemnified party shall have requested that an indemnifying party reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated herein effected without its written consent if (i) such settlement is entered into more than forty-five (45) days after receipt by such indemnifying party of the request for reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least thirty (30) days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(d) Contribution. If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid, payable or otherwise incurred by such indemnified party as a result of such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof), as incurred, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other hand from the offering of the Shares, or (ii) if the allocation provided by clause

15

(i) of this Section 8(d) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) of this Section 8(d) but also the relative fault of the Company on the one hand and the Underwriter on the other with respect to the statements, omissions, acts or failures to act which resulted in such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof) as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other with respect to such offering shall be deemed to be in the same proportion as the total proceeds from the offering of the Shares purchased by investors as contemplated by this Agreement (before deducting expenses) received by the Company bear to the total underwriting commissions received by the Underwriter in connection with the Offering, as set forth in the table on the cover page of the Prospectus. The relative fault of the Company on the one hand and the Underwriter on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriter on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement, omission, act or failure to act. The Company and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 8(d) be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage, expense, liability, action, investigation or proceeding referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing to defend or defending against or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding. Notwithstanding the provisions of this Section 8(d), the Underwriter shall not be required to contribute any amount in excess of the total commission received in cash by the Underwriter in connection with the Offering less the amount of any damages that the Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement, omission or alleged omission, act or alleged act or failure to act or alleged failure to act. 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.

(e) Notwithstanding any other provision of this Section 8, no party shall be entitled to indemnification and contribution under this Agreement in violation of Section 17(i) of the 1940 Act.

SECTION 9. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated either party hereto with prior written notice to the other party.

SECTION 10. No Advisory or Fiduciary Responsibility. The Company agrees that the Underwriter is acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Shares contemplated hereby. Additionally, the Underwriter is not advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether the Underwriter has advised or is advising the Company on other matters). The Company has conferred with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriter shall have no responsibility or liability to the Company or any other person with respect thereto. The Underwriter advises that it and its affiliates are engaged in a broad range of securities and financial services and that it or its affiliates may have business relationships or enter into contractual relationships with purchasers or potential purchasers of the Company’s securities. Any review by the Underwriter of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriter and shall not be on behalf of, or for the benefit of, the Company.

16

SECTION 11. Entire Agreement. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriter, solely with respect to the offering contemplated by this Agreement.

SECTION 12. Representations and Indemnities to Survive Delivery; Third Party Beneficiaries. The respective indemnities, agreements, representations, warranties and other statements of the Company, of its officers, and of the Underwriter set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriter or the Company or any of its or their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Shares sold hereunder and any termination of this Agreement. Each Investor shall be a third party beneficiary with respect to the representations, warranties, covenants and agreements of the Company set forth herein.

(g) The undersigned understands and agrees that if at any time it is discovered that any of the foregoing representations set forth in Sections 4(e) and (f) above are incorrect, or if otherwise required by applicable law or regulation related to money laundering and similar activities, the Company may, in its sole discretion, undertake appropriate actions to ensure compliance with applicable law or regulation, including but not limited to freezing, segregating or requiring the undersigned to sell such undersigned’s Shares.

(j) The undersigned acknowledges that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), the Company is required to obtain, verify and record information that identifies the undersigned, which information includes the name and address of the undersigned and other information that will allow the Company to identify the undersigned in accordance with the Patriot Act. Accordingly, the Company may request information from the undersigned that will help the Company to identify the undersigned (and in the case of subscribers that are entities, the undersigned’s beneficial owners), including without limitation the Company’s physical address, tax identification number, organizational documents, certificate of good standing, license to do business, or any other information that the Company deems necessary. The undersigned agrees to provide to the Company any additional information regarding the undersigned that the Company deems necessary or appropriate to ensure compliance with the Patriot Act, or any successor law, whether now or in the future.

Ladies and Gentlemen:

We have acted as counsel to Capital Southwest Corporation, a Texas corporation (the “Company”), in connection with the preparation and filing by the Company with the Securities and Exchange Commission (the “Commission”) of a registration statement on Form N-2 on July 13, 2018 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”), with respect to the offer, issuance and sale from time to time pursuant to Rule 415 under the Securities Act of up to $500,000,000 in aggregate of the following securities (the “Securities”):

The Registration Statement provides that the Securities may be issued from time to time in amounts, at prices, and on terms to be set forth in one or more supplements to the final prospectus included in the Registration Statement at the time it becomes effective.

This opinion letter is rendered in connection with the issuance and sale of (i) 100,000 shares of Common Stock in a direct registered offering (the “DRO Shares”), as described in the prospectus supplement, dated as of October 2, 2018 (the “ DRO Prospectus Supplement”), filed with the Commission pursuant to Rule 497 under the Securities Act and (ii) 600,000 shares of Common Stock in a “best efforts” underwritten offering (the “Underwritten Shares” and, together with the DRO Shares, the “Shares”), as described in the prospectus supplement, dated as of October 2, 2018 (the “ Underwritten Offering Prospectus Supplement”), filed with the Commission pursuant to Rule 497 under the Securities Act. The DRO Shares are being sold by the Company pursuant to certain subscription agreements, each dated as of October 2, 2018 (collectively, the “Subscription Agreements”), by and among the Company and the institutional investors named therein, and the Underwritten Shares are being sold by the Company pursuant to an underwriting agreement, dated as of October 2, 2018, by and between the Company and Sanders Morris Harris LLC (the “Underwriting Agreement”).

As counsel to the Company, we have participated in the preparation of the Registration Statement, the DRO Prospectus Supplement and the Underwritten Offering Prospectus Supplement and have examined the originals or copies, certified or otherwise identified to our satisfaction as being true copies, of the following:

With respect to such examination and our opinion expressed herein, we have assumed, without any independent investigation or verification, (i) the genuineness of all signatures on all documents submitted to us for examination, (ii) the legal capacity of all natural persons, (iii) the authenticity of all documents submitted to us as originals, (iv) the conformity to original documents of all documents submitted to us as conformed or reproduced copies and the authenticity of the originals of such copied documents, and (v) that all certificates issued by public officials have been properly issued. We also have assumed without independent investigation or verification the accuracy and completeness of all corporate records made available to us by the Company.

As to certain matters of fact relevant to the opinions in this opinion letter, we have relied upon certificates of public officials (which we have assumed remain accurate as of the date of this opinion) and upon certificates of officers of the Company. We have not independently established the facts, or in the case of certificates of public officials, the other statements, so relied upon.

This opinion letter is limited to the effect of the Texas Business Organizations Code, as in effect on the date hereof, and we express no opinion as to the applicability or effect of any other laws of the State of Texas or the laws of any other jurisdictions. Without limiting the preceding sentence, we express no opinion as to any state securities or broker-dealer laws or regulations thereunder relating to the offer, issuance and sale of the Shares. This opinion letter has been prepared, and should be interpreted, in accordance with customary practice followed in the preparation of opinion letters by lawyers who regularly give, and such customary practice followed by lawyers who on behalf of their clients regularly advise opinion recipients regarding, opinion letters of this kind.

On the basis of and subject to the foregoing, and in reliance thereon, and subject to the limitations and qualifications set forth in this opinion letter, we are of the opinion that the Shares have been duly authorized for issuance and, when issued and paid for in accordance with the terms and conditions of the Subscription Agreements or the Underwriting Agreement, as applicable, will be validly issued, fully paid and nonassessable.

The opinions expressed in this opinion letter (i) are strictly limited to the matters stated in this opinion letter, and without limiting the foregoing, no other opinions are to be implied and (ii) are only as of the date of this opinion letter, and we are under no obligation, and do not undertake, to advise the addressee of this opinion letter or any other person or entity either of any change of law or fact that occurs, or of any fact that comes to our attention, after the date of this opinion letter, even though such change or such fact may affect the legal analysis or a legal conclusion in this opinion letter.
