Date; and
(b)    a prorated Bonus for calendar year 2019, if any, of 83.29% (representing

Bonus, payable no later than March 15, 2020.
4.    Equity Awards.

whatsoever which you, or your heirs, executors, administrators and assigns have,
or may hereafter have, against the Released Parties arising out of or by reason
of any cause, matter or thing whatsoever, whether known or unknown, from the
beginning of the world to the date hereof, including without limitation the
Employment Agreement, any and all matters relating to your employment by any
NexTier Entity and the termination thereof, your compensation and employee
benefits as an employee of any NexTier Entity, your severance benefits from any
NexTier Entity, and all matters arising under any federal, state or local

including, but not limited to, claims arising under the Age Discrimination in
Employment Act of 1967, 29 U.S.C. § 621 et seq., Title VII of the Civil Rights
Act of 1964, 42 U.S.C. § 2000 et seq., the Americans with Disabilities Act of

of 1974, 29 U.S.C. § 1001 et seq., all as amended (the foregoing referred to
herein as the “General Release”). Notwithstanding the foregoing, nothing in this
Letter will: (i) affect any vested employee benefits to which you may be
entitled under any existing employee benefit plans of a NexTier Entity, (ii)
affect your equity interests in NexTier or in Keane Investor Holdings LLC, (iii)
affect your indemnification rights under NexTier’s corporate governing documents
or affect any of your indemnification and related rights under the

8.    No Pending or Future Claims. You will not bring any legal action against
any of the Released Parties for any claim waived and released under the General
Release. You represent and warrant that (a) no such claim has been filed to date
and (b) you have not assigned, transferred or purported to assign or transfer
any claim against the Released Parties.
9.    Continuing Obligations. You represent and warrant that you have complied
with and agree to continue to comply with your ongoing obligations under Section
7 of the Employment Agreement, which include, but are not limited to,
obligations regarding confidentiality, cooperation, non-solicitation or hire,
non-competition, property and nondisparagement, which are incorporated into this
Letter by reference.
10.    Return of NexTier Property. You agree that you have returned to NexTier
all property (including property purchased or paid for by NexTier in your
possession, custody or control) which belongs to NexTier, including any keys,
access cards, computers, cellphones, pagers or other equipment, and any NexTier
records, files, data and documents (whether on a work or personal computer, in
electronic format or otherwise, unaltered and unmodified, and whether
confidential in nature or not). You will immediately, upon request, report to
NexTier any passwords for your computer or other access codes for anything
associated with your employment with NexTier.
11.    Remedy for Breach; Reformation and Severability. You acknowledge and
agree that your breach or threatened breach of Section 9 of this Letter will
result in irreparable and continuing damage to the NexTier Entities for which
there may be no adequate remedy at law and that the NexTier Entities will be
entitled to seek equitable relief, including specific performance and injunctive
relief as remedies for any such breach or threatened or attempted breach,
without requiring the posting of a bond. You hereby consent to the grant of an
injunction (temporary or otherwise) against you or the entry of any other court
order against you prohibiting and enjoining you from violating, or directing you
to comply with, any provision of Section 9 of this Letter. You also agree that
such remedies will be in addition to any and all remedies, including damages,
available to the NexTier Entities against you for such breaches or threatened or
attempted breaches. In addition, without limiting the NexTier Entities’ remedies
for any breach of any restriction on you set forth in Section 7 of the
Employment Agreement (as incorporated herein pursuant to Section 9 of this
Letter), except as required by law, you will not be entitled to the Severance
Payments if you have breached the covenants applicable to you contained in
Section 7 of the Employment Agreement, you will immediately return to NexTier
any portion of the Severance Payments previously received by you upon such a
breach and, in the event of such breach, NexTier will have no obligation to pay
any portion of the Severance Payments that remains payable by NexTier under
Section 2 of this Letter. In case any provision of Section 9 of this Letter is
declared by a court of competent jurisdiction to be invalid, illegal or
unenforceable as written, you and NexTier agree that the court will modify and
reform such provision to permit enforcement to the greatest extent possible
permitted by law. If any term, provision, covenant or restriction of this
Letter, or any part thereof, is held by a court of competent jurisdiction of any
foreign, federal, state, county or local government, or any other governmental,
regulatory or administrative agency or authority to be invalid, void,
unenforceable or against public policy for any reason, then the remainder of the
terms, provisions, covenants and restrictions of this Letter will remain in full
force and effect and will in no way be affected, impaired or invalidated.
12.    Miscellaneous.
(a)    You acknowledge that you are not otherwise entitled to receive the
Severance Payments from NexTier by virtue of your employment with any NexTier
Entity or for any other reason.
(b)    You represent and warrant that you fully understand the terms of this
Letter and that you knowingly and voluntarily, of your own free will without any
duress, being fully informed and after due deliberation, accept its terms and
sign the same as your own free act. You further represent and warrant that,
except as set forth herein, no promises or inducements for this Letter have been
made, and you are entering into this Letter without reliance upon any statement
or representation by any of the Released Parties or any other person, concerning
any fact material hereto. You understand that as a result of your execution of
this Letter, you will not have the right to assert that NexTier unlawfully
terminated your employment or violated any rights in connection with your
employment or service.
(c)    You represent and warrant that you have no claims against the Released
Parties related to sexual harassment or sexual abuse.
13.    Effective Date of General Release.
(a)    The General Release is valid only if this Letter is signed by you and
returned to NexTier on or within twenty-two (22) calendar days of the date you
first receive this Letter. You acknowledge that NexTier has provided you with at
least twenty-one (21) calendar days from the date upon which this Letter is
first delivered to you within which to consider the terms and effect of the
General Release. If you elect to execute this Letter before the expiration of
the twenty-one (21) day period, you acknowledge that you have chosen, of your
own free will without any duress, to waive your right to the full twenty-one
(21) day period. You acknowledge and agree that any changes to this Letter from
the time it was first offered to you, whether material or immaterial, do not
restart the running of the twenty-one (21) day period.
(b)    You have seven (7) calendar days following the date you sign this Letter
during which to revoke the General Release, by notifying in writing Kevin M.
McDonald, Executive Vice President, Chief Administrative Officer, General
Counsel and Secretary of NexTier at the address for NexTier provided in Section
22. Provided you do not revoke the General Release, the General Release will
become effective on the eighth (8th) day following NexTier’s receipt of the
valid Letter signed by you. NexTier’s obligation to provide the Severance
Payments will automatically terminate if you revoke the General Release.
(c)    NexTier hereby advises you to consult with an attorney prior to signing
this Letter.
14.    Notice of Rights and Exceptions.
(a)    You understands that nothing contained in this Letter limits your ability
to file a charge or complaint with the Equal Employment Opportunity Commission,
the National Labor Relations Board, the Occupational Safety and Health
Administration, the Securities and Exchange Commission or any other federal,
state or local governmental agency or commission (“Government Agencies”). You
further understand that this Letter does not limit your ability to communicate
with any Government Agencies, including to report possible violations of federal
law or regulation, or making other disclosures that are protected under the
whistleblower provisions of federal law or regulation, or otherwise to
participate in any investigation or proceeding that may be conducted by any
Government Agency, including providing documents or other information, without
notice to NexTier. This Letter does not limit your right to receive an award for
information provided to any Government Agencies.
(b)    You will not be criminally or civilly liable under any federal or state
trade secret law for the disclosure of a trade secret that (i) is made (A) in
confidence to a federal, state or local government official, either directly or
indirectly, or to an attorney; and (B) solely for the purpose of reporting or
investigating a suspected violation of law; or (ii) is made in a complaint or
other document filed in a lawsuit or other proceeding, if such filing is made
under seal.
15.    Non-Admission; Inadmissibility. This Letter does not constitute an
admission by NexTier or any other Released Party that any action it took with
respect to you was wrongful, unlawful or in violation of any local, state or
federal act, statute or constitution, or susceptible of inflicting any damages
or injury on you, and NexTier specifically denies any such wrongdoing or
violation. This Letter’s execution and implementation may not be used as
evidence, and will not be admissible in a subsequent proceeding of any kind,
except one alleging a breach of this Letter.
16.    Entire Agreement. This Letter, including provisions of the Employment
Agreement incorporated herein by reference, constitutes the entire understanding
between the parties, and except as set forth herein, supersedes any and all
prior agreements or understandings between the parties with respect to the
subject matter hereof. Notwithstanding the foregoing (a) your awards pursuant
the Equity Plan will continue to be governed by the terms of the Equity Plan and
accompanying award agreements, and (b) this Agreement does not affect your
indemnification rights under NexTier’s corporate governing documents or any of
your indemnification and related rights under the indemnification Agreement
between you and Keane Group, Inc., dated as of January 9, 2017.
17.    Amendments and Waivers. No provisions of this Letter may be amended,
modified, waived or discharged except as agreed to in writing by the parties
hereto. The failure of a party to insist upon strict adherence to any term or
provision of this Letter on any occasion will not be considered a waiver thereof
or deprive that party of the right thereafter to insist upon strict adherence to
that term or provision or any other term of this Letter.
18.    Construction. Neither this Letter nor any provision hereof will be
construed against either of the parties on the basis of whether either of the
parties had a greater role in drafting it than the other party.
19.    Severability. If any provision of this Letter is found to be invalid or
unenforceable for any reason whatsoever, the remainder of this Letter will
remain in effect.
20.    Governing Law and Venue. This Letter will be governed by and construed in
accordance with the laws of Texas, without regard to any choice of law
provisions thereof. The parties acknowledge and agree that any claims, disputes
or controversies between the parties relating to or arising out of this Letter
will be resolved in accordance with Section 9.5(b) of the Employment Agreement,
which is incorporated into this Letter by reference.
21.    Section 409A. For purposes of Section 409A of the Internal Revenue Code
(“Section 409A”), your right to receive any installment payments will be treated
as a right to receive a series of separate and distinct payments. The parties
intend that you will have a “separation from service” from NexTier on the
Separation Date. You acknowledge that you are a “specified employee.” With
respect to any amounts that are payable to you under Section 3(a) of this Letter
(i) during the six (6) month period following the Separation Date, (ii)
constitute “nonqualified deferred compensation” under Section 409A, and (iii)
are payable as a result of your separation from service, then payment of such
amounts will be delayed until the first business day that is at least seven (7)
months following the Separation Date (or, if earlier, your death).
Notwithstanding the foregoing, you agree that each installment paid to you
pursuant to Section 3(a) of this Letter during the six (6) month period
following the Separation Date does not constitute “nonqualified deferred
compensation” pursuant to Treas. Reg. § 1.409A-1(b)(4) and Treas. Reg. §
1.409A-1(b)(9)(iii).
22.    Notices. Any notice or other communication required or which may be given
hereunder will be in writing and will be delivered personally, sent by facsimile
transmission or sent by certified, registered or express mail, postage prepaid
or overnight mail and will be deemed given when so delivered personally, or sent

of its terms, will be binding upon their representatives, heirs, executors,
administrators, successors and assigns.
