may be amended from time to time (hereinafter referred to each as a Fund and together as the Funds), and Hennessy Advisors, Inc., a California corporation (the Adviser).

RECITALS

WHEREAS, the Trust is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the Act), as an open-end management investment company; and

WHEREAS, the Trust desires to retain the Adviser, which is an investment adviser registered under the Investment Advisers Act of
1940, as amended, as the investment adviser to the Funds.

AGREEMENT

NOW,THEREFORE, the Trust and the Adviser do mutually promise and agree as follows:



|1. | Employment. The Trust hereby employs the Adviser to manage the investment and reinvestment of the assets of each Fund for the period and on the terms set forth
in this Agreement. The Adviser hereby accepts such employment for the compensation herein provided and agrees during such period to render the services and to assume the obligations herein set forth.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2. | Authority of the Adviser. The Adviser shall supervise and manage the investment portfolio of each Fund, and, subject to such policies as the trustees of the
Trust may determine, direct the purchase and sale of investment securities in the day to day management of each Fund. The Adviser shall for all purposes herein be deemed to be an independent contractor and shall, unless otherwise expressly provided
or authorized, have no authority to act for or represent the Trust or any Fund in any way or otherwise be deemed an agent of the Trust or any Fund. However, one or more shareholders, officers, directors or employees of the Adviser may serve as
trustees and/or officers of the Trust, but without compensation or reimbursement of expenses for such services from the Trust. Nothing herein contained shall be deemed to require the Trust to take any action contrary to its Agreement and Declaration
of Trust, as it may be amended from time to time, or any applicable statute or regulation, or to relieve or deprive the trustees of the Trust of their responsibility for, and control of, the affairs of the Trust.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3. | Use of Sub-Advisers. All services to be furnished by the Adviser under this Agreement may be furnished through the medium of any managers, officers or employees
of the Adviser or through such other parties (including, without limitation, a sub-adviser) as the Adviser may determine from time to time. Each sub-advisory agreement may provide that the applicable sub-adviser, subject to the control and
supervision of the Trusts Board of Trustees and the Adviser, shall have full investment discretion for the applicable Fund, shall make all determinations with respect to the investment of such Funds assets assigned to it and the purchase
and sale of portfolio securities with those assets, and shall take such steps as may be necessary to implement its investment decisions. Any delegation of duties pursuant to this paragraph shall comply with any applicable provisions of
Section 15 of the Act, except to the extent permitted by any exemptive order of the Securities and Exchange Commission or similar relief. The Adviser shall not be responsible or liable for the investment merits of any decision by a sub-adviser
to purchase, hold or sell a security for the applicable Funds portfolio; provided, however, that this provision shall not limit the Advisers obligation as a fiduciary to supervise each Funds investment program and the activities of
sub-advisers.

|5. | Compensation of the Adviser. For the services and facilities to be rendered, the Trust through each Fund shall pay to the Adviser an advisory fee, paid monthly,
based on the average daily net assets of the Fund, as determined by valuations made as of the close of each business day of the month. The advisory fee payable by each Fund is set forth on Schedule A hereto. For any month in which this Agreement is
not in effect for the entire month, such fee shall be reduced proportionately on the basis of the number of calendar days during which it is in effect and the fee computed upon the average daily net assets of the business days during which it is so
in effect.

|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7. | Exclusivity. The services of the Adviser to the Trust hereunder are not to be deemed exclusive and the Adviser shall be free to furnish similar services to
others as long as the services hereunder are not impaired thereby. Although the Adviser has permitted and is permitting the Trust and one or more Funds to use the name Hennessy, it is understood and agreed that the Adviser reserves the
right to use and to permit other persons, firms or corporations, including investment companies, to use such name, and that the Trust and the Funds will not use such name if the Adviser ceases to be each Funds sole investment adviser (not
including any sub-advisers engaged pursuant to Paragraph 3). During the period that this Agreement is in effect, the Adviser shall be each Funds sole investment adviser (not including any sub-advisers engaged pursuant to Paragraph 3).

|8. | Liability. In the absence of willful misfeasance, bad faith, gross negligence or reckless disregard of obligations or duties hereunder on the part of the

purchase, holding or sale of any security.

indirectly suffer or incur as a result of a material breach by the Adviser of its standard of care set forth in Paragraph 8. The Trust, on behalf of each Fund, agrees to indemnify the Adviser with respect to any loss, liability, judgment, cost or
penalty which the Adviser may directly or indirectly suffer or incur in any way arising out of the performance of its duties under this Agreement, except to the extent that such loss, liability, judgment, cost or penalty was a result of a material
breach by the Adviser of its standard of care set forth in Paragraph 8.

|10. | Brokerage Commissions. The Adviser, subject to the control and direction of the trustees of the Trust, shall have authority and discretion to select brokers and
dealers to execute portfolio transactions for each Fund and for the selection of the markets on or in which the transactions will be executed. The Adviser may cause each Fund to pay a broker-dealer which provides brokerage or research services, as
such services are defined in Section 28(e) of the Securities Exchange Act of 1934 (the Exchange Act), to the Adviser a commission for effecting a securities transaction in excess of the amount another broker-dealer would have
charged for effecting such transaction, if the Adviser determines in good faith that such amount of commission is reasonable in relation to the value of brokerage and research services provided by the executing broker-dealer viewed in terms of
either that particular transaction or the Advisers overall responsibilities with respect to the accounts as to which the Adviser exercises investment discretion (as defined in Section 3(a)(35) of the Exchange Act). The Adviser shall
provide such reports as the trustees of the Trust may reasonably request with respect to each Funds brokerage commissions, the manner in which that brokerage was allocated and brokerage and research services received.

|11. | Code of Ethics. The Adviser has adopted a written code of ethics complying with the requirements of Rule 17j-1 under the Act and has provided the Trust with a
copy of the code of ethics and evidence of its adoption. Upon written request of the Trust, the Adviser shall permit the Trust to examine any reports required to be made by the Adviser pursuant to Rule 17j-1 under the Act, to the extent such reports
are not required, pursuant to Rule 17j-1, to be made to the Trust.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|12. | Amendments. This Agreement may be amended by the mutual consent of the parties; provided, however, that in no event may it be amended without the approval of the

|13. | Termination. This Agreement may be terminated at any time with respect to a Fund, without the payment of any penalty, by the trustees of the Trust or by a vote
of the majority of the outstanding voting securities of that Fund, as defined in the Act, upon giving sixty (60) days written notice to the Adviser. This Agreement may be terminated by the Adviser at any time upon the giving of sixty
(60) days written notice to the Trust. This Agreement shall terminate automatically in the event of its assignment (as defined in Section 2(a)(4) of the Act). Subject to prior termination as hereinbefore provided, this Agreement
shall continue in effect for two (2) years from the date hereof and indefinitely thereafter, but only so long as the continuance after such two (2) year period is specifically approved annually by (i) the trustees of the Trust or by

(60) days thereafter.
