McMurray, PA 15317

Dear Timothy,

As previously discussed and publicly disclosed, your employment with CNX
Resources Corporation (the “Company”) will terminate effective December 31, 2019
(unless you earlier voluntarily terminate your employment with the Company or
you are earlier terminated by the Company “for cause”) (the earliest of such
dates being the “Termination Date”). As of the Termination Date, you are no
longer expected or required to provide any services to the Company, except as
provided in this agreement. Further, you agree that, effective as of the
Termination Date, you hereby resign from all other positions you hold as an
officer or director of the Company or any of its subsidiaries and affiliates.
Prior to the Termination Date you shall continue to be employed as an Executive
Vice President of the Company. In such capacity, you shall have such
responsibilities, powers and duties as may from time to time be prescribed by
the Chief Executive Officer or the Board of Directors, consistent with the role
of Executive Vice President, which may include: (i) the orderly transition of
the responsibilities and duties of the chief operating officer to the new chief
operating officer, (ii) maintaining and transitioning to the new chief operating
officer customer, commercial, financial, shareholder and other relationships
which are important to the Company, and (iii) providing advice and guidance to
the new chief operating officer, as requested by the new chief operating
officer. You shall devote as much of your working time and efforts to the
business and affairs of the Company and its subsidiaries as is necessary to
effectively carry out the foregoing duties and responsibilities. You shall not
directly or indirectly render any services of a business, commercial or
professional nature to any other person or organization, whether for
compensation or otherwise, without the prior written consent of the Company;
provided, however, that nothing in this agreement shall preclude you from
managing your personal investments and serving as a director of a not-for-profit
organization. In consideration for the foregoing, you will receive the
following:
1.
Ongoing Wages: Your wages based on your current salary for your employment up to
the Termination Date will be paid to you in accordance with the normal payroll
practices of the Company.

2.
Benefits: You shall be entitled to participate in all employee benefit plans
made available by the Company to its employees upon the terms and subject to the
conditions set forth in the applicable plan or arrangement up to the Termination
Date.

3.
Expenses: The Company shall reimburse you for all reasonable expense incurred by
you in the course of performing your duties up to the Termination Date, subject
to the Company’s requirements with respect to reporting and documentation of
expenses.

--------------------------------------------------------------------------------

At the Termination Date, as a consequence of the termination of your employment,
you are entitled to receive the following:
1.
Final Wages: Your wages for your work through your Termination Date already have
been paid to you or will be paid to you on the next payroll date when those
wages would otherwise be due.

2.
Accrued and Unused Vacation: The Company already has or will pay you for unused
vacation time for 2019 as of the Termination Date (less applicable withholdings
and deductions) on the next payroll date.

We remind you that, after the Termination Date, you continue to be bound by the
Company’s policies and your contractual commitments regarding the protection of
confidential business information, which of course are subject to any laws that
require or permit disclosure of such confidential information.
In addition to the compensation and benefits described above, in recognition of
your years of service to the Company and (i) provided that you do not
voluntarily terminate your employment by the Company prior to December 31, 2019;
(ii) provided that you are not terminated by the Company “for cause” prior to
December 31, 2019; and (iii) provided that you have delivered a signed Release
of claims (“Release No. 2”), substantially similar to the Release set forth
below and otherwise reasonably satisfactory to the Company’s General Counsel
within 21 days after the Termination Date and not revoked such Release No. 2
within the seven-day revocation period provided for in Release No. 2, the
Company will provide the following additional compensation and benefits (the
“Severance Payment and Benefits”) to you:
1.
Severance Payment: The Company will pay you a lump sum payment of $100,000 (less
applicable withholdings and deductions) on the first regular payroll date
following the Termination Date and your execution and return of the referenced
Release No. 2 and your non-revocation of such Release No. 2 during the seven-day
Revocation Period described below.

2.
Unemployment: The Company will not object to any application that you might make
for unemployment benefits. Your eligibility for such benefits will be determined
solely by the state where such an application for unemployment is filed.

3.
Non-Compete: Notwithstanding anything to the contrary contained herein or in any
other Company document or otherwise, you will not be precluded from working for
a competitor of the Company and its affiliates and subsidiaries.

Release No. 1

No. 1), as described herein, you shall release CNX, and all of its affiliated
companies, direct and indirect parents, subsidiaries, affiliates, successors,

former shareholders, partners, principals, members, directors, officers, agents,
employees, employee benefit plans, trustees, insurers and all others acting in
concert with them (collectively, the “Released Persons”), from any and all

--------------------------------------------------------------------------------

jurisdiction over any charge, complaint, proceeding, or action involving claims
released in this agreement, you agree that you will not accept, recover, or
receive any monetary damages or other relief from or in connection with that
charge, complaint, or proceeding. You agree that if a court of competent
jurisdiction determines that you are to be awarded damages under the WARN Act or
any other federal or state law, those damages would be offset by an amount equal
to your above severance payment minus $500. You also agree that you have not
assigned or transferred to another person or entity any interest in any of the
above stated claims.
You have certain rights that are not released by signing this letter agreement,
which includes this Release No. 1. Such Release No. 1 does not affect the
following: any rights or claims that may arise after the date this letter
agreement is executed; your right to enforce the Company’s obligations under
this agreement; any rights you may have to vested CNX Companies’ pension or
retirement benefits that you are entitled to on the date of execution of this
agreement and/or the Release by you; your right to receive workers’ compensation
benefits; your right to file a charge or complaint with any appropriate federal,
state, or local agency, such as the United States Equal Employment Opportunity
Commission; your right

--------------------------------------------------------------------------------

to participate in or cooperate with any such charge or complaint procedure; and
any right that cannot be waived as a matter of law. Any other claim you have or
might have is, however, released by such Release No. 1.
By signing this letter agreement, which includes this Release No. 1, you are
also representing and agreeing that, except for wages to be paid to you
regardless of whether you sign this letter agreement, as described herein, and
the Severance Payment and Benefits to be paid under the terms of this agreement,
you have been paid in full for all other wages and benefits to which you are
entitled.
***
You and the Company agree that certain materials, including, but not limited to,
information, data and other materials relating to customers, development
programs, costs, marketing, trading, investment, sales activities, promotion
credit and financial data, manufacturing processes, financial methods, plans or
the business and affairs of the Company and its affiliates, constitute
proprietary confidential information and trade secrets. Accordingly, you will
not at any time during or after your employment with the Company disclose or use
for your own benefit or purposes or the benefit or purposes of any Person, other
than the Company and any of its affiliates, any proprietary confidential
information or trade secrets. The foregoing obligations imposed by this
paragraph will not apply (i) in the course of the business of and for the
benefit of the Company, (ii) if such information has become, through no fault of
yours, generally known to the public, or (iii) if you are required by law to
make disclosure (after giving the Company notice and an opportunity to contest
such requirement). You agree that upon the Termination Date, you will
immediately return to the Company all memoranda, books, paper, plans,
information, letters and other data, and all copies thereof or therefrom, which
in any way relate to the business of the Company and its affiliates. You further
agree that you will not retain or use for your account at any time any trade
names, trademark or other proprietary business designation used or owned in
connection with the business of the Company or any of its Affiliates.
The Company agrees that if you are made a party, or are threatened to be made a
party, to any action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that you are or were a
director, officer or employee of the Company or are or were serving at the
request of the Company as a director, officer, member, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
including service with respect to employee benefit plans, you shall be
indemnified and held harmless by the Company to the fullest extent permitted or
authorized by applicable law and the Company’s certificate of incorporation or
bylaws, against all cost, expense, liability and loss (including, without
limitation, attorney’s fees, judgments, fines, ERISA excise taxes or penalties
and amounts paid or to be paid in settlement) reasonably incurred or suffered by
you in connection therewith, and such indemnification shall continue as to you
even if you have ceased to be a director, member, employee or agent of the
Company or other entity and shall inure to the benefit of your heirs, executors
and administrators.
The provisions of this letter agreement may be amended or waived only by a
written agreement executed and delivered by the Company and you. No other course
of dealing between the parties to this agreement or any delay in exercising any
rights hereunder will operate as a waiver of any rights of any such parties.
Notwithstanding the foregoing or any provisions of this letter agreement to the
contrary, the Company may at any time, with your consent, modify or amend any
provision of this agreement or take any other action, to the extent necessary or
advisable to ensure that this letter agreement complies with or is exempt from
Section 409A of the Internal Revenue Code of 1986, as amended, (the “Code”) and
that

--------------------------------------------------------------------------------

any payments or benefits under this agreement are not subject to interest and
penalties under Section 409A of the Code.
All covenants and agreements contained in this letter agreement by or on behalf
of any of the parties hereto will bind and inure to the benefit of the
respective heirs, successors and assigns of the parties hereto whether so
expressed or not, provided that you may not assign your rights or delegate your
obligations under this agreement without the written consent of the Company and
the Company may assign this agreement only to a successor to all or
substantially all of its assets.
If any dispute arises with regard to the interpretation and/or performance of
this letter agreement or Release No.1, as set forth above, or any of the
provisions contained therein, the parties agree to attempt to resolve the
dispute by telephone conference with a mediator jointly selected by the parties.
If the parties cannot resolve the dispute by such telephone conference, then the
parties agree to schedule and conduct a half-day mediation within thirty (30)
days of notice of the dispute and to share equally the costs of such mediation.
If a party refuses to mediate, then such party thereby waives any claim for and
recovery of attorneys’ fees or costs incurred in any litigation brought
regarding this agreement. Otherwise, if the parties are unable to resolve their
dispute by mediation, then the prevailing party or parties in any resulting
litigation shall be entitled to recover reasonable attorneys’ fees, costs and
expenses, including the costs of mediation. This agreement may be executed
simultaneously in two or more counterparts, any one of which need not contain
the signatures of more than one party, but all of which counterparts taken
together will constitute one and the same agreement. The descriptive headings of
this agreement are inserted for convenience only and do not constitute a part of
this agreement.
The Company may withhold from any amounts payable under this letter agreement
such federal, state, local or foreign taxes as shall be required to be withheld
pursuant to any applicable law or regulation.
This letter agreement shall become effective on the date set forth below. On and
after the effective date, this letter agreement constitutes the entire agreement
among the parties and supersedes any prior understandings, agreements or
representations by or among the parties, written or oral, that may have related
in any way to the subject matter hereof.
ALL QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY AND INTERPRETATION OF THIS
AGREEMENT WILL BE GOVERNED BY THE INTERNAL LAW OF PENNSYLVANIA, WITHOUT REGARD
TO PRINCIPLES OF CONFLICT OF LAWS.

agreement to consider the terms of this agreement as proposed by the Company,
including the terms of Release No. 1, as set forth herein. Any modification to
these proposed terms, whether material or immaterial, does not restart the
running of the 21-day period.
If you decide to sign this letter agreement, and thereby accept the terms of
this agreement, you may then revoke your acceptance of it up to seven days after
signing it (“Revocation Period 1”), by notifying me in writing before the
expiration of Revocation Period 1. This agreement will not become effective
until the expiration of Revocation Period 1; provided, however, that the
Company’s obligation to pay the Severance Payment and Benefits will not become
effective until the expiration of Revocation Period 2, as defined herein. On the
Termination Date, the referenced Release No. 2, as described above, will be
provided to you and if you decide to sign Release No. 2, and thereby accept the
terms of Release No. 2, you may then revoke your acceptance of it up to seven
(7) days after signing it (“Revocation Period 2”), by notifying me in writing
before the expiration of Revocation Period 2. Release No. 2 and

--------------------------------------------------------------------------------

the Company’s obligation to pay the Severance Payment and Benefits will not
become effective until the expiration of Revocation Period 2.
