If the enclosed proxy card is properly executed and returned in time to be voted at the Annual Meeting, the Shares represented thereby will be voted in accordance with the instructions marked thereon. Unless instructions to the contrary are marked thereon, a properly executed proxy will be voted “FOR” the election of the nominees for Trustee named in this Proxy Statement.  Any shareholder of record who has given a proxy has the right to revoke it at any time prior to its exercise either by attending the Annual Meeting and voting his or her Shares in person, by submitting a letter of revocation or by a later-dated proxy delivered to the Secretary of the Fund at 100 Wall Street, 11th Floor, New York, NY 10005 before the Annual Meeting or at the Annual Meeting. Broker-dealers and other nominees holding shares of the Fund in “street name” for the benefit of their customers and clients will request the instructions of such customers and clients on how to vote their shares on

1

each Proposal before the Annual Meeting.  A signed voting instruction card or other authorization by a beneficial owner of the Fund’s Shares that does not specify how the beneficial owner’s Shares should be voted will be deemed an instruction to vote “FOR” the election of the nominees for Trustee named in this Proxy Statement.  Beneficial owners should consult their broker or other nominees for instructions as to how to revoke any voting instructions.

The presence at the Annual Meeting, in person or by proxy, of holders of record of at least 33 1/3% of the outstanding Shares entitled to vote constitutes a quorum for the transaction of business (a “Quorum”) at the Annual Meeting. In the event that a Quorum is not present at the Meeting, or in the event that a Quorum is present but sufficient votes to approve any of the proposals are not received, the Chairman, the Trustees (or their designees) or a majority of the votes properly cast upon the question of adjourning a meeting, either in person or by proxy, of the Annual Meeting may adjourn the Annual Meeting without notice, other than announcement at the Annual Meeting, to a date not more than 120 calendar days after the original date of the Annual Meeting. If the adjournment is for more than 120 calendar days from the original date of the Annual Meeting or a new record date is fixed for the adjourned meeting, notice of any such adjourned meeting will be given to each shareholder of record entitled to vote at the adjourned meeting. A shareholder vote may be taken on a proposal in the Proxy Statement prior to any such adjournment if sufficient votes have been received for approval of such proposal.

The Fund has one class of capital stock consisting of common shares, par value $0.001 per Share. Each Share is entitled to one vote at the Annual Meeting with respect to each matter to be voted on, with pro rata voting rights for any fractional Shares. No Shares have cumulative voting rights with respect to the election of Trustees. Trustees are elected by the affirmative vote of the holders of a majority of the Shares outstanding and entitled to vote, assuming a quorum is present at the Annual Meeting.  On the record date, April 5, 2018 (the “Record Date”), 7,418,989.602 Shares of the Fund were issued and outstanding.

To the knowledge of the Fund, the following shareholder(s) or “group,” as that term is defined in Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), are beneficial owners of more than 5% of the outstanding Shares as of April 5, 2018 based on public filings and/or information provided by such persons.

(1)               The Charger Corporation (“Charger”) is the General Partner of both First Trust Portfolios L.P. (“FTP”) and First Trust Advisors L.P. (“FTA”). FTP acts as sponsor of certain unit investment trusts which hold Shares of the Fund.  FTA, an affiliate of FTP, acts as portfolio supervisor of the unit investment trusts sponsored by FTP. Information shown was obtained from a Schedule 13G/A filed by FTP, FTA and Charger with the SEC on January 11, 2018 reporting share ownership as of December 31, 2017.  Based on that filing, FTP, FTA and Charger do not have sole or shared voting power, but do have the shared power to dispose or direct the disposition of 1,562,196 Shares.

(2)               Advisors Asset Management, Inc. (“Advisors”) is sponsor of several unit investment trusts which hold Shares of the Fund. Information shown was obtained from a Schedule 13G/A filed by Advisors with the SEC on February 1, 2018 reporting share ownership as of December 31, 2017.  Based on that filing, Advisors maintains the sole power to vote 609,440 Shares and the sole power to dispose or direct the disposition of 744,891 Shares.

The following table sets forth the dollar range of equity securities in the Fund beneficially owned by each Trustee and executive officer as of the Record Date.  As of that date, the Fund’s Trustees and executive officers, as a group, owned less than 1% of the Fund’s outstanding Shares. The fund complex consists of the Fund and the Eagle Growth and Income Opportunities Fund (“EGIF”), a closed-end fund registered under the Investment Company Act of 1940, as amended (the “1940 Act”).  EGIF commenced operations in June 2015.

PROPOSAL 1: ELECTION OF TRUSTEES

The Board currently consists of five Trustees, four of whom are not “interested persons” (as that term is defined in the 1940 Act) of the Fund (the “Independent Trustees”).  The Trustees are divided into three classes and are elected for staggered terms of three years each, with a term of office of each class of Trustees expiring at the third annual meeting of shareholders after the election of such class of Trustees.  Each Trustee will hold office for the term to which he or she is elected and until his or her successor is duly elected and qualified.

The classes of Trustees are indicated below:

Nominees to Serve Until 2021 Annual Meeting

Joseph L. Morea

Michael Perino

Trustees Serving Until 2019 Annual Meeting

Ronald J. Burton

Steven A. Baffico

Trustee Serving Until 2020 Annual Meeting

Laurie Hesslein

THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE ELECTION OF THE NOMINEES NAMED IN THIS PROXY STATEMENT.

Messrs. Morea and Perino, each a Class I Trustee of the Fund, have each been nominated to serve for a three-year term to expire at the Fund’s 2021 Annual Meeting and when his successor is duly elected and qualified.  Each of Messrs. Morea and Perino has consented to continue to serve as a Trustee if elected at the Annual Meeting.

All properly executed proxies will be voted (unless such authority has been withheld in the proxy or revoked as described herein) “FOR” the nominees named in this Proxy Statement.  The Board knows of no reason why either of the nominees will be unable to serve, but in the event of any such unavailability, the proxies received will be voted for such substitute nominee or nominees as the Board may recommend.

Information About Each Trustee’s and Each Nominee’s Experience, Qualifications, Attributes or Skills

Certain biographical and other information relating to the Trustees and nominees, including their year of birth, positions with the Fund, principal occupations and other board memberships for the past five years are shown below.

(1)         The business address of each Trustee is care of THL Credit Senior Loan Fund at 100 Wall Street, New York, NY 10005.

(2)         “Independent Trustees” are Trustees who are not “interested persons” (as such term is defined in the 1940 Act) of the Fund.

(3)         “Interested Trustees” are “interested persons” (as such term is defined in the 1940 Act) of the Fund.  Mr. Baffico is considered an “interested person” because of his affiliation with the Adviser.

(4)         Nominee for election. If elected, his term will expire at the 2021 Annual Meeting and when his successor is duly elected and qualifies.

(5)         The fund complex consists of the Fund and EGIF.

(6)         This column only includes directorships of companies required to report to the SEC under the 1934 Act (i.e., public companies) or other investment companies registered under the 1940 Act held by the Trustee.

Additional information about each Trustee follows that describes some of the specific experiences, qualifications, attributes or skills that each Trustee possesses which the Board believes has prepared him or her to be an effective Trustee.  The Board believes that the significance of each Trustee’s experience, qualifications, attributes or skills is an individual matter (meaning that experience that is important for one Trustee may not have the same value for another) and that these factors are best evaluated at the Board level, with no single Trustee, or particular factor, being indicative of Board effectiveness.  However, the Board believes that Trustees need to have the ability to critically review, evaluate, question and discuss information

5

provided to them, and to interact effectively with Fund management, service providers and counsel, in order to exercise effective business judgment in the performance of their duties.  Experience relevant to having this ability may be achieved through a Trustee’s educational background; business, professional training or practice (e.g., accounting, finance or law); public service or academic positions; experience from service as a board member or as an executive of investment funds, public companies or significant private or not-for-profit entities or other organizations; and/or other life experiences.  To assist them in evaluating matters under federal and state law, the Independent Trustees are counseled by their own independent legal counsel, who participates in Board meetings and interacts with the Adviser, and also may benefit from information provided by the Fund’s counsel; both counsel to the Independent Trustees and the Fund have significant experience advising funds and fund board members.  The Board and its committees have the ability to engage other experts as appropriate.  The Board evaluates its performance on an annual basis.

Board Composition and Leadership Structure

The 1940 Act requires that at least 40% of the Trustees be Independent Trustees. Currently, four of the five Trustees are Independent Trustees.  The Independent Trustees exercise their informed business judgment to appoint an individual of their choosing to serve as Chairman, regardless of whether the Trustee happens to be independent or a member of management.  The Board has concluded that its current leadership structure, in which the Chairman of the Board is an Independent Trustee and not affiliated with the Adviser, is appropriate and in the best interest of shareholders. In light of the services provided to the Fund daily by the Adviser and the responsibilities of the Adviser to the Fund, the Board believes it appropriate and in the best interest of shareholders to have a separate President who is an active Adviser employee.

Board’s Oversight Role

The Board’s primary role is oversight of the management of the Fund.  As is the case with virtually all investment companies, service providers to the Fund, primarily the Adviser, THL Credit Advisors LLC, the Fund’s sub-adviser (the “Sub-Adviser”), and affiliates of the Adviser, have responsibility for the day-to-day management of the Fund, which includes responsibility for risk management (including management of investment performance and investment risk, valuation risk, issuer and counterparty credit risk, compliance risk and operational risk).  As part of its oversight, the Board, acting at its scheduled meetings, regularly interacts with and receives reports from senior personnel of the Adviser and the Sub-Adviser.  The Board’s Audit Committee (which consists of all of the Independent Trustees) meets regularly, and between meetings the Audit Committee Chair has access to the Fund’s independent registered public accounting firm and to the Fund’s Treasurer.  The Board also receives periodic presentations from senior personnel of the Adviser, the Sub-Adviser, or their affiliates regarding risk management, as well as periodic presentations regarding specific operational, compliance or investment areas, such as personal trading, valuation, credit and investment research.  The Adviser, the Sub-Adviser and other service providers have adopted a variety of policies, procedures and controls designed to address the Fund’s particular risks.  However, it is not possible to eliminate, or even to mitigate, all of the risks applicable to the Fund.  The Board receives reports from Fund counsel and the Independent Trustees’ own independent legal counsel regarding regulatory, compliance and governance matters.  The Board’s oversight role does not make the Board a guarantor of Fund investments or of Fund activities or the activities of any of the Fund’s service providers.

Compensation of Trustees and Executive Officers

During the fiscal year ended December 31, 2017, the Board held five (5) meetings for TSLF and five (5) meetings for EGIF.  Each Trustee of the Fund attended all of the meetings of the Board and of any Committee of which he was a member. The compensation paid by the Fund to the Independent Trustees for the fiscal year ended December 31, 2017 is set forth below.  No compensation is paid by the Fund to the Interested Trustee or officers of the Fund.

(1)         The fund complex consists of the Fund and EGIF.

(2)         Ms. Hesslein began serving as a Trustee effective March 29, 2017.

The fund complex reimbursed the Independent Trustees a total of $560.52 for out-of-pocket expenses incurred in attending the Board and Committee meetings, as applicable, for the period ended December 31, 2017.

Executive Officers of the Fund

The following table provides information concerning each of the executive officers of the Fund, including their year of birth, positions with the Fund and principal occupations for the past five years.

(1)         The business address of each officer, with the exception of Mr. Huntington and Ms. Dotolo, is care of THL Credit Senior Loan Fund at 100 Wall Street, New York, NY 10005.  Mr. Huntington and Ms. Dotolo are employees of Foreside Fund Officer Services, LLC, and each has a business address of 10 High Street Suite 302, Boston, MA 02110.

(2)         Elected by, and serves at the pleasure of, the Board.

Audit Committee

The Board has an Audit Committee comprised of each of the Fund’s Independent Trustees, each of whom is also “independent” as defined under the listing standards of the New York Stock Exchange (“NYSE”). Ms. Hesslein was appointed to the Audit Committee effective March 29, 2017. Mr. Morea simultaneously serves on the audit committees of more than three public companies, and the Board has determined that his simultaneous service on the audit committees of other public companies does not impair his ability to effectively serve on the Audit Committee. During the Fund’s fiscal year ended December 31, 2017, the Audit Committee held three (3) joint committee meetings on behalf of TSLF and EGIF.  The functions of the Audit Committee are to (a) assist the Board in its oversight of (i) the integrity of the financial statements of the Fund; (ii) the independent registered public accounting firm’s (the “Independent Auditor”) qualifications and independence; (iii) the performance of the Fund’s Independent Auditor; and (iv) the compliance by the Fund with legal and regulatory requirements and (b) prepare an audit committee report as required by Regulation S-K under the 1934 Act. The Audit Committee Charter, which describes the Audit Committee’s purpose and duties, is available at HTTP://FWCAPITALADVISORS.COM/TSLF.  This reference to the website does not incorporate the content of the website into this Proxy Statement.

Audit Committee Report

The Audit Committee oversees the Fund’s financial reporting process on behalf of the Board.  Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal control over financial reporting.  In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed with management the audited financial statements in the Fund’s Annual Report for the fiscal year ended December 31, 2017.

The Audit Committee reviewed with the Independent Auditor, which is responsible for expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, its judgments as to the quality, not just the acceptability, of the Fund’s accounting principles and such other matters as are required to be discussed with the committee under the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”).  In addition, the Audit Committee has discussed with the Independent Auditor the Independent Auditor’s independence from management and the Fund, including the Independent Auditor’s letter and the matters in the written disclosures required by the PCAOB provided to the Audit Committee.

The members of the Audit Committee are not, and do not represent themselves to be, professionally engaged in the practice of auditing or accounting and are not employed by the Fund for accounting, financial management, or internal control purposes. Accordingly, the Audit Committee’s oversight does not provide an independent basis to determine that management has maintained appropriate accounting and/or financial reporting principles and policies, or internal controls and procedures, designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committee’s considerations and discussions referred to above do not guarantee that the audit of the Fund’s financial statements has been carried out in accordance with the standards of the PCAOB or that the financial statements are presented in accordance with generally accepted accounting principles (United States).

Based on its consideration of the audited financial statements and the discussions referred to above with management and the Independent Auditor, and subject to the limitations on the responsibilities and role of the Audit Committee set forth in the Audit Committee Charter and those discussed above, the Audit Committee recommended to the Fund’s Board of Trustees that the Fund’s audited financial statements be included in the Fund’s Annual Report for the fiscal year ended December 31, 2017.

This report was submitted by the Audit Committee of the Fund’s Board

Nominating and Governance Committee

The Board has a Nominating and Governance Committee comprised of each of the Fund’s Independent Trustees. Ms. Hesslein was appointed to the Nominating and Governance Committee effective March 29, 2017. The Nominating and Governance Committee of the Fund met once during the fiscal year ended December 31, 2017. The functions of the Nominating and Governance Committee include identifying, selecting or recommending qualified nominees to be elected to the Board at the annual meetings of shareholders (consistent with criteria approved by the Board); identifying, selecting or recommending qualified nominees to fill any vacancies on the Board or a committee thereof (consistent with criteria approved by the Board); overseeing the evaluation of the Board; and undertaking such other duties and responsibilities as may from time to time be delegated by the Board to the Nominating and Governance Committee.  The Nominating and Governance Committee charter is available at HTTP://FWCAPITALADVISORS.COM/TSLF.  This reference to the website does not incorporate the content of the website into this Proxy Statement.

The Nominating and Governance Committee has not established any specific minimum qualifications that must be met for the Committee to consider a nominee. In nominating candidates, including candidates recommended by shareholders as provided below, the Nominating and Governance Committee will take into consideration such factors as it deems appropriate, including, to the extent required, compliance with the independence and other applicable requirements of the federal securities laws, the listing standards of the NYSE and any other applicable laws, rules or regulations; a candidate’s experiences, qualifications, attributes or skills described above under “Information About Each Trustee’s and Each Nominee’s Experience, Qualifications, Attributes or Skills”; and personal and professional integrity, character, time availability in light of other commitments, dedication and conflicts of interest.  The Fund’s Nominating and Governance Committee may consider whether a potential nominee’s professional experience, education, skills, and other individual qualities and attributes, including gender, race or national origin, would provide beneficial diversity of skills, experience or perspective to the Board’s membership and collective attributes. Such considerations will vary based on the Board’s existing membership and other factors, such as the strength of a potential nominee’s overall qualifications relative to diversity considerations. The Fund’s Nominating and Governance Committee will consider Trustee candidates recommended by shareholders and submitted in accordance with applicable law and procedures as described in this Proxy Statement (see “Submission of Shareholder Proposals” below).

Other Board-Related Matters

Shareholders who wish to send communications to the Board should send them to the Secretary of the THL Credit Senior Loan Fund at 100 Wall Street, New York, NY 10005. All such communications will be directed to the Board’s attention.

The Fund does not have a formal policy regarding Trustee attendance at the annual meetings of shareholders.

REQUIRED VOTE

Provided a Quorum is present, the election of each of Messrs. Morea and Perino as a Trustee (Proposal 1) requires the affirmative vote of the holders of a majority of the outstanding Shares entitled to vote.

For purposes of electing each of Messrs. Morea and Perino as a Trustee, neither abstentions nor broker-non votes will be counted as votes cast. Broker non-votes (which are treated as shares present but not entitled to vote)  will have no effect on Proposal 1. Abstentions (which are treated as shares present and entitled to vote) will have the same effect as a vote “against” Proposal 1.

ADDITIONAL INFORMATION

Independent Registered Public Accounting Firm

RSM US LLP (“RSM”), 80 City Square, Boston, MA, 02129, has been selected to serve as the Fund’s independent registered public accounting firm for the Fund’s fiscal year ending December 31, 2018. A representative of RSM will not be present at the Annual Meeting, but will be available by telephone to respond to appropriate questions and will have an opportunity to make a statement, if the representative desires.

Set forth in the table below are the audit fees and non-audit related fees billed to the Fund by RSM for professional services for the fiscal years ended December 31, 2016 and 2017.

* “Tax Fees” are those fees related to RSM’s tax consulting services, including primarily the review of the Fund’s income tax returns.

** “All Other Fees” include the aggregate fees billed for products and services provided by RSM, other than the reported services.

The Fund’s Audit Committee Charter requires that the Audit Committee pre-approve all audit and non-audit services to be provided by RSM to the Fund, and all non-audit services to be provided by RSM to the Fund’s Adviser and Sub-Adviser and any entity controlling, controlled by or under common control with the Fund’s Adviser (“Affiliates”) that provides on-going services to the Fund, if the engagement relates directly to the operations and financial reporting of the Fund. Alternatively, the Audit Committee has delegated authority to one of its members to pre-approve such services, subject to subsequent reporting to the Audit Committee. All of the audit and non-audit services described above for which RSM billed the Fund fees for the fiscal years specified above were pre-approved by the Fund’s Audit Committee, as required.

The aggregate non-audit fees billed by RSM for services rendered to the Fund and rendered to the Adviser or its Affiliates that provide ongoing services to the Fund for the fiscal years ended December 31, 2017 and 2016 were $38,750 and $55,750, respectively.

Investment Adviser, Sub-Adviser and Administrator

Four Wood Capital Advisors, LLC serves as the Fund’s investment adviser. The principal executive office of the Adviser is 100 Wall Street, 11th Floor, New York, NY 10005.

THL Credit Advisors LLC serves as the Fund’s investment sub-adviser pursuant to a Subadvisory Agreement between the Adviser and the Sub-Adviser.  The principal executive office of the Sub-Adviser is 100 Federal Street, 31st Floor, Boston, MA 02110.

The Bank of New York Mellon, located at 101 Barclay Street, New York, NY 10026, serves as administrator to the Fund.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the 1934 Act and Section 30(h) of the 1940 Act require the Fund’s Trustees and executive officers, certain persons affiliated with the Fund and persons who beneficially own more than 10% of a registered class of the Fund’s

11

securities to file reports of ownership and changes of ownership with the SEC. Trustees, officers and greater-than-10% shareholders are required by SEC regulations to furnish the Fund with copies of such forms they file. Based solely upon its review of the copies of such forms received by it and representations from certain of such persons, the Fund believes that during the Fund’s fiscal year ended December 31, 2017, all such filing requirements applicable to such persons were met, except that, due to administrative oversight, one late Form 3 filing was made for Ms. Hesslein.
