(“Sub-Adviser”). 
 RECITALS 

WHEREAS, Manager is registered as an investment adviser under the Investment Advisers Act of 1940, as amended (the “Advisers
Act”); 
 WHEREAS, Manager has entered into an Investment Advisory Agreement, dated as of October 26, 2018 (the
“Advisory Agreement”), with Hennessy Funds Trust (the “Trust”), an investment company registered under the Investment Company Act of 1940, as amended (the “Investment Company Act”); 

WHEREAS, Sub-Adviser is registered as an investment adviser under the Advisers Act; 

WHEREAS, Manager desires to retain Sub-Adviser to render investment advisory and other services to the
funds specified in Schedule A hereto, as amended from time to time, each a series of the Trust (each a “Fund” and together, the “Funds”), in the manner and on the terms hereinafter set forth; 

WHEREAS, Manager has the authority, subject to the approval of the Trustees of the Trust (the “Trustees”), and, if required
under the Investment Company Act, the shareholders of each Fund, to select one or more sub-advisers for each Fund; and 

WHEREAS, Sub-Adviser is willing to furnish such services to Manager and each Fund. 

AGREEMENT 
 NOW,
THEREFORE, Manager and Sub-Adviser agree as follows: 
  

	1.	 APPOINTMENT OF SUB-ADVISER 

Manager hereby appoints Sub-Adviser to act as a sub-adviser for
each Fund for the period and on the terms and conditions of this Agreement. 
  

	2.	 ACCEPTANCE OF APPOINTMENT 

A. Sub-Adviser accepts that appointment and agrees to render the services herein set forth, for the
compensation herein provided. 

 B. The assets of each Fund will be maintained in the custody of a custodian (who shall be
identified by Manager in writing). Sub-Adviser will not have custody of any securities, cash, or other assets of any Fund and will not be liable for any loss resulting from any act or omission of the custodian
other than acts or omissions arising in reasonable reliance on instructions of Sub-Adviser. The custodian will be responsible for the custody, receipt, and delivery of securities and other assets of each Fund,
and Sub-Adviser shall have no authority responsibility or obligation with respect to the custody receipt or delivery of securities or other assets of any Fund. The Fund shall be responsible for all custodial
arrangements, including the payment of all fees and charges to the custodian. 
  

	3.	 SERVICES TO BE RENDERED BY SUB-ADVISER TO THE TRUST

 A. As sub-adviser to each Fund,
Sub-Adviser will coordinate the investment and reinvestment of the assets of the Fund and determine the composition of the assets of the Fund, in accordance with the terms of this Agreement, the Fund’s
Prospectus and the Fund’s Statement of Additional Information (the “SAI”) (as each may be updated or amended, from time to time) and subject to the direction, supervision, and control of Manager and the Trustees. Prior to the
commencement of Sub-Adviser’s services hereunder, Manager shall provide Sub-Adviser with current copies of each Fund’s Prospectus and SAI. Manager undertakes
to provide Sub-Adviser with copies or other written notice of any amendments, modifications, or supplements to each Fund’s Prospectus and SAI and Sub-Adviser will
not need to comply until a copy has been provided to Sub-Adviser. 
 B. Sub-Adviser may place orders for the execution of transactions with or through such brokers, dealers or banks as Sub-Adviser may select and, subject to Section 28(e) of
the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and other applicable law, may pay commissions on transactions in excess of the amount of commissions another broker or dealer would have charged. Sub-Adviser will seek best execution under the circumstances of the particular transaction taking into consideration the full range and quality of a broker’s services in placing brokerage including, among other
things, the value of research provided as well as execution capability, commission rate, financial responsibility, and responsiveness to Sub-Adviser (the determinative factor is not the lowest possible
commission cost, but whether the transaction represents the best qualitative execution for a Fund). In no event shall Sub-Adviser be under any duty to obtain the lowest commission or best net price for a Fund
on any particular transaction. Sub-Adviser is not under any duty to execute transactions for a Fund before or after transactions for other like accounts managed by
Sub-Adviser. Sub-Adviser may aggregate sales and purchase orders of securities or derivatives held in a Fund with similar orders being made simultaneously for other
portfolios managed by Sub-Adviser if, in Sub-Adviser’s reasonable judgment, such aggregation shall result in an overall economic benefit to the Fund. Manager
understands and agrees that when such aggregation does occur the actual prices obtained will be averaged and the applicable Fund will be deemed to have purchased or sold its proportionate share of the securities involved at such average price.
Notwithstanding the foregoing, Sub-Adviser will not effect any transaction with a broker or dealer that is an “affiliated person” (as defined under the Investment Company Act) of Sub-Adviser or Manager without the prior approval of Manager. Manager shall provide Sub-Adviser with a list of brokers or dealers that are affiliated persons of Manager. 

C. Manager understands and agrees and has advised the Trustees that Sub-Adviser performs investment
management services for various clients and may take action with respect to any of its other clients that may differ from action taken or from the timing or nature of action taken by Sub-Adviser for a Fund. Sub-Adviser’s authority hereunder shall not be impaired because of the fact that it may effect transactions with respect to securities for its own account, or for other accounts that it manages, that are
identical or similar to securities to which it may effect transactions for a Fund at the same or similar times. 

 D. Sub-Adviser will provide Manager with copies of Sub-Adviser’s current policies and procedures that relate to Sub-Adviser’s duties described in this Agreement adopted in accordance with Rule 206(4)-7 under the Advisers Act. To the extent a Fund is required by the Investment Company Act to adopt any such policy or procedure, Manager will submit such policy or procedure to the Trustees for
adoption by each of the Funds, with such modifications or additions thereto as the Trustees may recommend. Sub-Adviser’s Chief Compliance Officer shall provide to Manager’s Chief Compliance Officer
or his or her delegate the following: 
 (i) a report of any material changes to
Sub-Adviser’s policies and procedures described in Section 3(D) above on a quarterly basis; 

(ii) a report of any “material compliance matters,” as defined by
Rule 38a-1 under the Investment Company Act, that have occurred in connection with Sub-Adviser’s policies and procedures on a quarterly basis; 

(iii) a summary of Sub-Adviser’s Chief Compliance Officer’s report
identifying the material compliance matters relevant to the Funds with respect to the annual review of Sub-Adviser’s policies and procedures pursuant to
Rule 206(4)-7 under the Advisers Act; and 
 (iv) an annual certification
regarding Sub-Adviser’s compliance with Rule 206(4)-7 under the Advisers Act and Section 38a-1 of the Investment
Company Act, as well as the foregoing subparagraphs (i) through (iii). 
 E. Sub-Adviser will
maintain and preserve all accounts, books, and records with respect to each Fund as are required of an investment adviser of a registered investment company pursuant to the Investment Company Act and the Advisers Act and the rules thereunder and
shall file with the Securities and Exchange Commission (“SEC”) all forms pursuant to Sections 13(d), 13(f), and 13(g) of the Exchange Act, with respect to its duties as are set forth herein. 

F. Sub-Adviser shall reasonably cooperate with Manager and/or the Trust in responding to any
regulatory or compliance examinations or inspections (including any information requests) relating to the Trust, a Fund or Manager brought by any governmental or regulatory authorities. 

G. Sub-Adviser will, unless and until otherwise directed by Manager, exercise all rights of security
holders with respect to securities held by each Fund; provided that Sub-Adviser will not be responsible for any other corporate actions relating to the securities in which assets of the Fund’s investment
portfolio are invested, including administrative filings, such as proofs or claims in class actions. 
 H.
Sub-Adviser, in connection with its rights and duties with respect to the Funds and the Trust shall use the care, skill, prudence and diligence under the circumstances then prevailing that a prudent person
acting in a like capacity and familiar with such matters would use in the conduct of an enterprise of a like character and with like aims. 

	4.	 COMPENSATION OF SUB-ADVISER 

As compensation for providing services in accordance with this Agreement, Manager will pay Sub-Adviser
those fees as set forth in Schedule A, calculated based on the relevant Fund’s average daily net assets and payable monthly. Manager and Sub-Adviser agree that all fees shall become due and owing to Sub-Adviser promptly after the termination date of Sub-Adviser with respect to any Fund and that the amount of such fees shall be calculated by treating the termination date
as the next fee computation date. The annual base fee will be prorated for such fees owed through the termination date. 
  

	5.	 REPRESENTATIONS OF MANAGER 

Manager represents, warrants, and agrees that: 

A. Manager has been duly authorized by the Trustees to delegate to Sub-Adviser the provision of
investment services to each Fund as contemplated hereby. 
 B. The Trust has adopted a written code of ethics complying with the
requirements of Rule 17j-1 under the Investment Company Act and will provide Sub-Adviser with a copy of such code of ethics. 

C. Manager (i) is registered as an investment adviser under the Advisers Act and will continue to be so registered for so long as this
Agreement remains in effect, (ii) is not prohibited by the Investment Company Act, the Advisers Act, or other law, regulation, or order from performing the services contemplated by this Agreement, (iii) has met and will seek to continue to
meet for so long as this Agreement is in effect, any other applicable federal or state requirements, or the applicable requirements of any regulatory or industry self-regulatory agency necessary to be met in order to perform the services
contemplated by this Agreement, (iv) has the full power and authority to enter into and perform the services contemplated by this Agreement, and (v) will promptly notify Sub-Adviser of the occurrence
of any event that would disqualify Manager from serving as investment manager of an investment company pursuant to Section 9(a) of the Investment Company Act or otherwise. 

 

	6.	 REPRESENTATIONS OF SUB-ADVISER

A. Sub-Adviser (i) is registered as an investment adviser under the Advisers Act and will continue

to be met in order to perform the services contemplated by this Agreement, (iv) has the full power and authority to enter into and perform the services contemplated by this Agreement, and (v) will promptly notify Manager of the occurrence

 B. Sub-Adviser has adopted a written code of ethics
complying with the requirements of Rule 17j-1 under the Investment Company Act and Rule 204A-1 under the Advisers Act and will provide Manager with a copy of
such code of ethics. 
 C. Sub-Adviser agrees to maintain an appropriate level of errors and
omissions or professional liability insurance coverage. 
 D. Sub-Adviser will promptly notify
Manager of (i) any change in its governing documents, which if implemented would mean that it would be unable to perform its obligations hereunder, or (ii) its knowledge that any of the warranties or representations given in this Agreement
is incorrect or would be incorrect if given at the time concerned. 
 E. Sub-Adviser will, to the
extent required under applicable regulatory requirements, disclose to Manager (i) any financial condition that is likely to impair its ability to meet its contractual commitments hereunder, (ii) any legal or disciplinary event that is

Sub-Adviser’s ownership structure. 
  

	7.	 NON-EXCLUSIVITY 

The services of Sub-Adviser to Manager, the Funds, and the Trust are not to be deemed to be exclusive,
and Sub-Adviser shall be free to render investment advisory or other services to others and to engage in other activities. It is understood and agreed that the directors, officers, and employees of Sub-Adviser are not prohibited from engaging in any other business activity or from rendering services to any other person, or from serving as partners, officers, directors, trustees, or employees of any other firm
or corporation. 
  

	8.	 SUPPLEMENTAL ARRANGEMENTS 

Sub-Adviser may from time to time employ or associate itself with any person it believes to be
particularly suited to assist it in providing the services to be performed by Sub-Adviser hereunder; provided that no such person shall perform any services with respect to the Funds that would constitute an
assignment or require a written advisory agreement pursuant to the Investment Company Act. Any compensation payable to such persons shall be the sole responsibility of Sub-Adviser, and neither Manager nor the Trust shall have any obligations with
respect thereto or otherwise arising under this Agreement. 
  

	9.	 DURATION OF AGREEMENT 

This Agreement shall become effective upon the date first above written, provided that this Agreement shall not take effect with respect to a
Fund unless it has first been approved (i) by a vote of a majority of those trustees of the Trust who are not “interested persons” (as defined in the Investment Company Act) of any party to this Agreement (“Independent
Trustees”), cast in person at a meeting called for the purpose of voting on such approval, and (ii) by vote of a majority of the outstanding voting securities (as defined in the Investment Company Act) of the Fund or as permitted by Rule 2a-6 of the Investment Company Act. This Agreement shall continue in effect for a period more than two years from the date of its execution only so long as such continuance is specifically approved at
least annually by the Trustees; provided that in such event such continuance shall also be approved by the vote of a majority of the Independent Trustees cast in person at a meeting called for the purpose of voting on such approval. 

	10.	 TERMINATION OF AGREEMENT 

This Agreement may be terminated with respect to any Fund at any time, without the payment of any penalty, by a vote of the majority of the
Trustees, by the vote of a majority of the outstanding voting securities of such Fund, or by Manager on 60 days’ prior written notice to Sub-Adviser (and to Manager, as appropriate). In addition, this
Agreement may be terminated with respect to any Fund by Sub-Adviser upon 60 days’ prior written notice to Manager. This Agreement will automatically terminate, without the payment of any penalty, in the
event the Advisory Agreement is assigned (as defined in the Investment Company Act) or terminates for any other reason. This Agreement will also terminate upon written notice to the other party that the other party is in material breach of this
Agreement, unless the breaching party cures such breach to the reasonable satisfaction of the party alleging the breach within 30 days after written notice. Any “assignment” (as that term is defined in the Investment Company Act) of this
Agreement will result in automatic termination of this Agreement. Sub-Adviser will promptly notify the Trust and Manager of any such assignment and of any changes in key personnel who are either the portfolio
manager(s) of the Funds named in the Prospectus and/or SAI or senior management of Sub-Adviser, in each case prior to or promptly after such change. Sub-Adviser agrees
to bear all reasonable legal, printing, mailing, proxy, and related expenses of the Trust and Manager, if any, arising out of an assignment of this Agreement by Sub-Adviser. 

 

	11.	 AMENDMENTS TO THE AGREEMENT 

This Agreement may be amended by the parties with respect to any Fund only by written agreement. It is understood that certain material
amendments may require approval of a Fund’s shareholders. Additional Funds may be added to Schedule A by written agreement of Manager and Sub-Adviser. 

 

	12.	 ASSIGNMENT 

Sub-Adviser shall not assign this Agreement. Any assignment (as that term is defined in the Investment
Company Act) of this Agreement shall result in the automatic termination of this Agreement, as provided in Section 10 hereof. Notwithstanding the foregoing, no assignment shall be deemed to result from any changes in the directors, officers, or
employees of such Sub-Adviser except as may be provided to the contrary in the Investment Company Act or the rules or regulations thereunder.

All notices required to be given pursuant to this Agreement shall be delivered or mailed to the address listed below of each applicable party

	14.	 SEVERABILITY AND SURVIVAL 

Should any portion of this Agreement for any reason be held to be void in law or in equity, this Agreement shall be construed, insofar as is
possible, as if such portion had never been contained herein. Section 15, Section 16, and Section 17 shall survive the termination of this Agreement. 
  

	15.	 GOVERNING LAW AND LANGUAGE 

The provisions of this Agreement shall be construed and interpreted in accordance with the laws of the State of Delaware, or any of the
applicable provisions of the Investment Company Act. To the extent that the laws of the State of Delaware or any of the provisions in this Agreement conflict with applicable provisions of the Investment Company Act, the latter shall control. 

 

	16.	 INTERPRETATION 

Any question of interpretation of any term or provision of this Agreement having a counterpart in or otherwise derived from a term or provision
of the Investment Company Act shall be resolved by reference to such term or provision of the Investment Company Act and to interpretations thereof, if any, by the United States courts or, in the absence of any controlling decision of any such
court, by rules, regulations, or orders of the SEC validly issued pursuant to the Investment Company Act. Specifically, the terms “vote of a majority of the outstanding voting securities,” “interested persons,”
“assignment,” and “affiliated persons” as used herein shall have the meanings assigned to them by Section 2(a) of the Investment Company Act. In addition, where the effect of a requirement of the Investment Company Act
reflected in any provision of this Agreement is relaxed by a rule, regulation, or order of the SEC, whether of special or of general application, such provision shall be deemed to incorporate the effect of such rule, regulation, or order. 

	17.	 CONFIDENTIALITY 

Each party shall treat as confidential all Confidential Information (as that term is defined below) of the other and use such information only
in furtherance of the purposes of this Agreement. Each party shall limit access to the Confidential Information to its affiliates, employees, consultants, auditors, and regulators who reasonably require access to such Confidential Information and
shall otherwise maintain policies and procedures designed to prevent disclosure of the Confidential Information. For purposes of this Agreement, Confidential Information shall include all non-public business
and financial information, methods, plans, techniques, processes, documents, and trade secrets of a party. Confidential Information shall not include anything that (i) is or lawfully becomes in the public domain, other than as a result of a
breach of an obligation hereunder, (ii) is furnished to the applicable party by a third party having a lawful right to do so, or (iii) was known to the applicable party at the time of the disclosure. 

In accordance with Regulation S-P, if non-public personal
information regarding any party’s customers or consumers is disclosed to the other party in connection with this Agreement, the other party receiving such information will not disclose or use that information other than as necessary to carry
out the purposes of this Agreement. 
  

	18.	 USE OF NAME 

During the term of this Agreement, Manager shall have permission to use Sub-Adviser’s name in the
offering and marketing of any Fund, and agree to furnish Sub-Adviser, for its prior approval (such approval not to be unreasonably withheld), all prospectuses, brochures, advertisements, promotional materials,
web based information, proxy statements, shareholder reports, and other similar informational materials that are to be made available to shareholders of a Fund or to the public and that refer to Sub-Adviser in
any way. Sub-Adviser agrees that Manager may request that Sub-Adviser approve use of a certain type of marketing material, and that Manager need not provide for approval
each additional piece of marketing material that is substantially the same type. 
  

	19.	 LIMITATION OF LIABILITY 

Sub-Adviser is hereby expressly put on notice of the limitation of shareholder liability as set forth
in the Trust’s Declaration of Trust and agrees that obligations, if any, assumed by the Trust pursuant to this Agreement shall be limited in all cases to the Trust and its assets, and if the liability relates to one or more series, the
obligations hereunder shall be limited to the respective assets of the Fund. Sub-Adviser further agrees that it shall not seek satisfaction of any such obligation from the shareholders or any individual
shareholder of the Fund(s), nor from the Trustees or any individual Trustee. The assets of a Fund shall be available only to satisfy the liabilities and obligations of that Fund, and not the liabilities or obligations of any other Fund. The
obligations of each of the Funds under this agreement are several and not joint, and are included together in this Agreement solely for the sake of convenience. 

 Sub-Adviser shall not be liable for, and Manager
will not take any action against Sub-Adviser or hold Sub-Adviser liable for, any error of judgment or mistake of law or for any loss suffered by the Funds (including,
without limitation, by reason of the purchase, sale or retention of any security) in connection with the performance of Sub-Adviser’s duties under this Agreement, except for a loss resulting from willful
misfeasance, bad faith, or gross negligence on the part of Sub-Adviser in the performance of its duties under this Agreement, or by reason of its reckless disregard of its obligations and duties under this
Agreement. 
  

	20.	 AUTHORITY TO EXECUTE TRANSACTION DOCUMENTS 

Subject to any other written instructions of Manager or the Trust, Sub-Adviser is hereby appointed
agent and attorney-in-fact for the limited purposes of executing, on behalf of each Fund specified on Schedule A hereto, the following: account documentation,
transaction term sheets and confirmations, certifications regarding the Fund’s status as an accredited investor, qualified institutional buyer, or qualified purchaser, and certifications regarding other factual matters as may be requested by
brokers, dealers, or counterparties in connection with its management of the Fund’s assets. However, nothing in this section shall be construed as imposing a duty on Sub-Adviser to act in its capacity as attorney-in-fact for a Fund. Any person dealing with Sub-Adviser in its capacity as attorney-in-fact hereunder for a Fund is hereby expressly put on notice that Sub-Adviser is acting solely in the capacity as an agent of the Fund and that any such
person must look solely to the Fund for enforcement of any claim against Fund, as Sub-Adviser assumes no personal liability to such person whatsoever for obligations of the Fund entered into by Sub-Adviser in its capacity as attorney-in-fact for the Fund. 

 

	21.	 CYBERSECURITY AND BUSINESS CONTINUITY 

Sub-Adviser shall establish, implement, and maintain documented procedures to ensure the appropriate
identification, monitoring, detection, and mitigation of information technology related risks of Sub-Adviser as they affect the Funds on an ongoing basis. Specifically,
Sub-Adviser shall take the following actions: (1) implement documented cybersecurity procedures to identify threats and to prevent and detect security events and incidents and put in place safeguards to
protect all information and data relating to the Funds against unauthorized access or use by a third party or misuse, damage, or destruction by any person; (2) ensure that appropriate information technology and cyber risk assessments are
conducted at regular intervals; (3) ensure that the effectiveness of its information technology systems, controls, and cybersecurity arrangements are reviewed and tested on a periodic basis, and, where weaknesses are identified as part of this
review process, remediate such weaknesses in a timely manner; (4) provide all relevant information relating to its information technology risk management and cybersecurity procedures as may be reasonably requested by the Trustees from time to
time and, upon request, make a presentation to the Trustees on such procedures; (5) ensure that training on cybersecurity awareness is delivered to its employees on a periodic basis; (6) put in place a documented cybersecurity incident
response and recovery plan that sets down the actions Sub-Adviser will take during and after a cybersecurity incident; (7) document and implement a business continuity plan that enables Sub-Adviser to maintain business operations and services impacting the Funds in the event of a disruption; (8) document and implement an adequate and appropriate disaster recovery plan that enables it to
recover from and resume provision of services to the Funds on a timely basis in the event of a disaster or emergency situation; and (9) promptly notify the Trustees when Sub-Adviser becomes aware of any
(a) failure or significant malfunction of any hardware or software used by Sub-Adviser that would impact the provision of services to the Funds, (b) loss of data relating to the Funds by Sub-Adviser, or (c) action taken through the use of computer networks that results in an actual or potential adverse effect on Sub-Adviser’s information system or
data residing on that system. 

	22.	 ENTIRE AGREEMENT 

This Agreement contains the entire understanding and agreement of the parties with respect to each Fund. 

 

	23.	 HEADINGS 

The headings in the sections of this Agreement are inserted for convenience of reference only and shall not constitute a part hereof.
