CODE OF BUSINESS CONDUCT AND ETHICS

Introduction

        Ethics are important to Main Street Capital Corporation ("Main Street" or the "Company") and to its management. Main Street is committed to the highest ethical standards and to conducting its business with the highest level of integrity. This code of business conduct and ethics (the "Code") has been adopted by Main Street in order to establish applicable policies, guidelines, and procedures that promote ethical practices and conduct by Main Street and all its employees, officers, and directors.

        All officers, directors and employees of Main Street are responsible for maintaining this level of integrity and for complying with the policies contained in this Code. If you have a question or concern about what is proper conduct for you or anyone else, please raise these concerns with any member of management, or follow the procedures outlined in applicable sections of this Code.

Purpose of the Code

        This Code is intended to:

•

help you recognize ethical issues and take the appropriate steps to resolve these issues;



•

deter ethical violations and avoid any abuse of position of trust and responsibility;



•

maintain confidentiality of our business activities;



•

assist you in complying with applicable securities laws;



•

assist you in reporting any unethical or illegal conduct; and



•

reaffirm and promote our commitment to a corporate culture that values honesty and accountability.

        All employees, as a condition of employment or continued employment, will acknowledge in writing that they have received a copy of this Code, read it, and understand that the Code contains our expectations regarding their conduct. All employees will receive any updates and updated versions of this Code and will be required to read and acknowledge such updates.

Conflicts of Interest

        You must avoid any conflict, or the appearance of a conflict, between your personal interests and our interests. A conflict exists when your personal interest in any way interferes with our interests, or when you take any action or have any interest that may make it difficult for you to perform your job objectively and effectively. For example, a conflict of interest probably exists if:

•

you cause us to enter into business relationships with you or a member of your family, or invest in companies affiliated with you or a member of your family;



•

you use any non-public information about us, our customers or our other business partners for your personal gain, or the gain of a member of your family; or



•

you use or communicate confidential information obtained in the course of your work for your or another's personal benefit.

Corporate Opportunities

        Each of us has a duty to advance the legitimate interests of Main Street when the opportunity to do so presents itself. Therefore, you may not:

•

take for yourself personally opportunities, including investment opportunities, discovered through the use of your position with us, or through the use of our property or information;



•

use our property, information, or position for your personal gain or the gain of a family member; or



•

compete, or prepare to compete, with us.

Confidentiality

        You must not disclose confidential information regarding us, our affiliates, our lenders, our clients, or our other business partners, unless disclosure is authorized or required by law. Confidential information includes all non-public information that might be harmful to, or useful to the competitors of, Main Street, our affiliates, our lenders, our clients, or our other business partners. Even after you leave Main Street, this obligation continues until the information becomes publicly available.

Fair Dealing

        You must endeavor to deal fairly with our customers, suppliers and business partners, or any other companies or individuals with whom we do business or come into contact with, including fellow employees and our competitors. You must not take unfair advantage of these or other parties by means of:

•

manipulation;



•

concealment;



•

abuse of privileged information;



•

misrepresentation of material facts; or



•

any other unfair-dealing practice.

Protection and Proper Use of Company Assets

        Our assets are to be used only for legitimate business purposes. You should protect our assets and ensure that they are used efficiently.

        Incidental personal use of telephones, fax machines, copy machines, personal computers and similar equipment is generally allowed if there is no significant added cost to us, it does not interfere with your work duties, and is not related to an illegal activity or to any outside business.

Compliance with Applicable Laws, Rules and Regulations

        Each of us has a duty to comply with all laws, rules and regulations that apply to our business. Highlighted below are some of the key compliance guidelines that must be followed.

•

Insider trading.  It is against the law to buy or sell securities using material information that is not available to the public. Individuals who give this "inside" information to others may be liable to the same extent as the individuals who trade while in possession of such information. You must not trade in our securities, or the securities of our affiliates, our lenders, our clients, or our other business partners while in the possession of "inside" information. All employees are required to be familiar and comply with our Insider Trading Policy and Procedures.

•

"Whistleblower" protections.  It is against the law to discharge, demote, suspend, threaten, harass, or discriminate in any manner against an employee who provides information or otherwise assists in investigations or proceedings relating to violations of federal securities laws or other federal laws prohibiting fraud against shareholders. You must not discriminate in any way against an employee who engages in these "whistleblower" activities.



•

Investment Company Act requirements.  A separate code of ethics has been established to comply with the Investment Company Act of 1940 and is applicable to those persons designated in such code.



•

Document Retention.  You must adhere to appropriate procedures governing the retention and destruction of records consistent with applicable laws, regulations and our policies. You may not destroy, alter or falsify any document that may be relevant to a threatened or pending lawsuit or governmental investigation.

        Please talk to our Chief Compliance Officer if you have any questions about how to comply with the above regulations and other laws, rules and regulations.

        In addition, we expect you to comply with all of our policies and procedures that apply to you. We may modify or update our policies and procedures in the future, and may adopt new policies and procedures from time to time. You are also expected to observe the terms of any confidentiality agreement, employment agreement or other similar agreement that applies to you.

Equal Opportunity, Harassment

        We are committed to providing equal opportunity in all of our employment practices including selection, hiring, promotion, transfer, and compensation of all qualified applicants and employees without regard to race, color, sex or gender, sexual orientation, religion, age, national origin, handicap, disability, citizenship status, or any other status protected by law. With this in mind, there are certain behaviors that will not be tolerated. These include harassment, violence, intimidation, and discrimination of any kind involving race, color, religion, gender, sexual orientation, age, national origin, citizenship status, handicap, disability, marital status, or any other status protected by law.

Political Activities

        Main Street encourages its employees to be actively involved in the civic affairs of the communities in which they live. When speaking on public issues, however, employees should do so only as individual citizens of the community and must be careful not to create the impression that they are acting for, or representing the views of, Main Street. Additionally, Main Street and its employees are prohibited from making any contribution or giving a gift to a state or local political candidate, official, party or organization that would be prohibited by applicable law. In order for the Company to determine whether a gift or political contribution may be prohibited, employees are required to provide advance notice to the Chief Compliance Officer in advance of a proposed contribution.

        The Chief Compliance Officer retains discretion to monitor all business activities between the Company and the provider or recipient of any gift or political contribution in connection with this policy. Any questions regarding this policy or the application of this policy should be directed to the Chief Compliance Officer or Chief Executive Officer.

Loans

        No employee may borrow funds from or become indebted to any person, business or company having business dealings or a relationship with Main Street, except with respect to customary personal loans (e.g., home mortgage loans, automobile loans, lines of credit, etc.), unless the arrangement is disclosed in writing and receives prior written approval from the Chief Compliance Officer of the

3

Company. No employee may use the Company's name, position in a particular market or goodwill to receive any benefit on loan transactions without the prior express written consent of the Chief Compliance Officer of the Company.

Accuracy of Company Records

        We require honest and accurate recording and reporting of information in order to make responsible business decisions. This includes such data as quality, safety, and personnel records, as well as financial records.

        All financial books, records and accounts must accurately reflect transactions and events, and conform both to required accounting principles and to our system of internal controls. No false or artificial entries may be made.

Retaining Business Communications

        The law requires us to maintain certain types of corporate records, usually for specified periods of time. Failure to retain those records for those minimum periods could subject us to penalties and fines, cause the loss of rights, obstruct justice, place us in contempt of court, or seriously disadvantage us in litigation.

        From time to time we establish retention or destruction policies in order to ensure legal compliance. We expect you to fully comply with any published records retention or destruction policies, provided that you should note the following exception: If you believe, or we inform you, that our records are relevant to any litigation or governmental action, or any potential litigation or action, then you must preserve those records until we determine the records are no longer needed. This exception supersedes any previously or subsequently established destruction policies for those records. If you believe that this exception may apply, or have any questions regarding the possible applicability of that exception, please contact our Chief Compliance Officer.

Media Relations

        We must speak with a unified voice in all dealings with the press and other media. As a result, our Chief Executive Officer, President, Chief Operating Officer, Chief Financial Officer or other designated persons will serve as our contact persons for media seeking information about Main Street. Any requests from the media must be referred to our Chief Executive Officer, President, Chief Operating Officer, Chief Financial Officer or other designated persons.

Intellectual Property Information

        Information generated in our business is a valuable asset. Protecting this information plays an important role in our growth and ability to compete. Such information includes business and research plans; objectives and strategies; trade secrets; unpublished financial information; salary and benefits data; lender and other business partner lists. Employees who have access to our intellectual property information are obligated to safeguard it from unauthorized access and:

        All reports will be investigated and whenever possible, requests for confidentiality shall be honored. And, while anonymous reports will be accepted, please understand that anonymity may hinder or impede the investigation of a report. All cases of questionable activity or improper actions will be reviewed for appropriate action, discipline or corrective actions. Whenever possible, we will keep confidential the identity of employees, officers or directors who are accused of violations, unless or until it has been determined that a violation has occurred.

        There will be no reprisal, retaliation or adverse action taken against any employee who, in good faith, reports or assists in the investigation of, a violation or suspected violation, or who makes an inquiry about the appropriateness of an anticipated or actual course of action.

        In the case of a confidential, anonymous submission, employees should set forth their concerns in writing and forward them in a sealed envelope to the Chairperson of the Audit Committee, in care of our Chief Compliance Officer, such envelope to be labeled with a legend such as: "To be opened by the Audit Committee only."
