         so long as such changes are similarly applicable to executive employees
         generally.

ARTICLE 5: EFFECT OF TERMINATION ON COMPENSATION; ADDITIONAL PAYMENTS

         5.1 TERMINATION OTHER THAN AN INVOLUNTARY TERMINATION. If Executive's
employment hereunder shall terminate upon expiration of the term provided in
Section 3.1 hereof because either party has provided the notice contemplated in
such paragraph, or if Executive's employment hereunder shall terminate for any
other reason except those described in Sections 5.2 and 5.3, then all
compensation and all benefits to Executive hereunder shall continue to be
provided until the date of such termination of employment and such compensation
and benefits shall terminate contemporaneously with such termination of
employment.

         5.2 INVOLUNTARY TERMINATION OTHER THAN DURING A CHANGE OF CONTROL
PERIOD. Subject to the provisions of Section 5.6 hereof, if Executive's
employment by Company or any subsidiary thereof or successor thereto shall be
subject to an Involuntary Termination which occurs prior to a Change of Control
or after the expiration of a Change of Control Period, then Company shall, as
additional compensation for services rendered to Company (including its
subsidiaries), pay to Executive the following amounts and take the following
actions after the last day of Executive's employment with Company:

                  (a) Pay Executive the Monthly Severance Amount on the first
         day of each month throughout the Severance Period; provided, however,
         that if commencement of such payments would cause any part of the
         Monthly Severance Amount to be subject to additional taxes and interest
         under Section 409A of the Code, then the payment of the Monthly
         Severance Amount shall be deferred to the earliest date upon which such
         payments can commence without being subject to such additional taxes
         and interest and the first payment of the Monthly Severance Amount
         shall include all amounts that would have been paid prior to the date
         of such payment but for the deferral required pursuant to this
         sentence.

                  (b) During the portion, if any, of the Severance Period that
         Executive is eligible to elect and elects to continue coverage for
         himself and his eligible dependents under Company's group health plans
         under the Consolidated Omnibus Budget Reconciliation Act of 1985, as
         amended, and/or Sections 601 through 608 of the Employee Retirement
         Income Security Act of 1974, as amended, Company shall promptly
         reimburse Executive on a monthly basis for the difference between the
         amount Executive pays to effect and continue such coverage and the
         employee contribution amount that active senior executive employees of
         Company pay for the same or similar coverage under Company's group
         health plans.

         5.3 INVOLUNTARY TERMINATION DURING A CHANGE OF CONTROL PERIOD. Subject
to the provisions of Section 5.6 hereof, if Executive's employment by Company or
any subsidiary thereof or successor thereto shall be subject to an Involuntary
Termination during a Change of Control Period, then Company shall, as additional
compensation for services rendered to Company (including its subsidiaries), pay
to Executive the following amounts and take the following actions after the last
day of Executive's employment with Company:



                                       8
<PAGE>


                  (a) Pay Executive a lump sum cash payment in an amount equal
         to the Severance Amount on or before the fifth day after the last day
         of Executive's employment with Company; provided, however, that if the
         lump sum cash payment would be subject to additional taxes and interest
         under Section 409A of the Code, then payment of the lump sum cash
         payment shall be deferred to the earliest date upon which such amount
         can be paid without being subject to such additional taxes and
         interest.

                  (b) Cause any and all outstanding options to purchase common
         stock of Company held by Executive to become immediately exercisable in
         full and cause Executive's accrued benefits under any and all
         nonqualified deferred compensation plans sponsored by Company to become
         immediately nonforfeitable.

                  (c) Cause Executive and those of his dependents (including his
         spouse) who were covered under Company's medical and dental benefit
         plans on the day prior to Executive's Involuntary Termination to
         continue to be covered under such plans (or to receive equivalent
         benefits) throughout the Severance Period at no greater cost to
         Executive than that applicable to a similarly situated Company
         executive who has not terminated employment; provided, however, that
         (i) such coverage shall terminate if and to the extent Executive
         becomes eligible to receive medical and dental coverage from a
         subsequent employer (and any such eligibility shall be promptly
         reported to Company by Executive), (ii) if Executive (and/or his
         spouse) would have been entitled to retiree medical and/or dental
         coverage under Company's plans had he voluntarily retired on the date
         of such Involuntary Termination, then such coverages shall be continued
         as provided under such plans, and (iii) such coverage to Executive (or
         the receipt of equivalent benefits) shall be provided under one or more
         insurance policies so that reimbursement or payment of benefits to
         Executive thereunder shall not result in taxable income to Executive
         (or, if any such reimbursement or payment of benefits is taxable, then
         Company shall pay to Executive an amount as shall be required to hold
         Executive harmless from any additional tax liability resulting from the
         failure by Company to so provide insurance policies so that
         reimbursement or payment of benefits to Executive thereunder shall not
         result in taxable income to Executive).

         5.4 INTEREST ON LATE PAYMENTS. If any payment provided for in Section
5.2 or Section 5.3 hereof is not made when due, then Company shall pay to
Executive interest on the amount payable from the date that such payment should
have been made under such Section until such payment is made, which interest
shall be calculated at 2% plus the prime or base rate of interest announced by
JPMorgan Chase Bank (or any successor thereto) at its principal office in New
York, and shall change when and as any such change in such prime or base rate
shall be announced by such bank.

         5.5 PARACHUTE PAYMENTS. Notwithstanding anything to the contrary in
this Agreement, if Executive is a "disqualified individual" (as defined in
Section 280G(c) of the Code), and the benefits provided for in this Article,
together with any other payments and benefits which Executive has the right to
receive from Company and its Affiliates, would constitute a "parachute payment"
(as defined in Section 280G(b)(2) of the Code), then the benefits provided
hereunder (beginning with any benefit to be paid in cash hereunder) shall be
either (1) reduced (but not below zero) so that the present value of such total
amounts and



                                       9
<PAGE>


benefits received by Executive from Company will be one dollar ($1.00) less than
three times Executive's "base amount" (as defined in Section 280G(b)(3) of the
Code) and so that no portion of such amounts and benefits received by Executive
shall be subject to the excise tax imposed by Section 4999 of the Code or (2)
paid in full, whichever produces the better net after-tax position to Executive
(taking into account any applicable excise tax under Section 4999 of the Code
and any other applicable taxes). The determination as to whether any such
reduction in the amount of the benefits provided hereunder is necessary shall be
made by the Compensation Committee in good faith. If a reduced cash payment is
made and through error or otherwise that payment, when aggregated with other
payments and benefits from Company (or its Affiliates) used in determining if a
"parachute payment" exists, exceeds one dollar ($1.00) less than three times
Executive's base amount, then Executive shall immediately repay such excess to
Company upon notification that an overpayment has been made. Nothing in this
Section 5.5 shall require Company to be responsible for, or have any liability
or obligation with respect to, Executive's excise tax liabilities under Section
4999 of the Code.

         5.6 RELEASE AND FULL SETTLEMENT. As a condition to the receipt of any
severance compensation and benefits under this Agreement, Executive will enter
into and deliver to the Company a separate full release and waiver substantially
in the form attached hereto as Exhibit A (with such changes to such form as the
Company may reasonably require to reflect the circumstances relating to the
termination of Executive's employment and/or changes in applicable law).
Notwithstanding anything to the contrary in this Agreement, severance
compensation and other benefits will not be payable by the Company unless and
until the release has been executed by Executive, has not been revoked and is no
longer subject to revocation by Executive.

         5.7 LIQUIDATED DAMAGES. In light of the difficulties in estimating the
damages for an early termination of Executive's employment under this Agreement,
Company and Executive hereby agree that the payments, if any, to be received by
Executive pursuant to this Article 5 shall be received by Executive as
liquidated damages.

         5.8 OTHER BENEFITS. This Agreement governs the rights and obligations
of Executive and Company with respect to Executive's base salary and certain
perquisites of employment. Except as expressly provided herein, Executive's
rights and obligations both during the term of his employment and thereafter
with respect to stock options, restricted stock, incentive and deferred
compensation, life insurance policies insuring the life of Executive, and other
benefits under the plans and programs maintained by Company shall be governed by
the separate agreements, plans, and other documents and instruments governing
such matters.

ARTICLE 6: NON-SOLICITATION OBLIGATIONS

         6.1 GENERAL. As part of the consideration for Company's employment of
Executive and the compensation and benefits that may be paid to Executive
hereunder; to protect the trade secrets and confidential information of Company
or its Affiliates that will in the future be disclosed or entrusted to
Executive, the business good will of Company or its Affiliates that will in the
future be developed in Executive, or the business opportunities that will in the
future be disclosed or entrusted to Executive by Company or its Affiliates; and
as an additional incentive for Company to enter into this Agreement, Company and
Executive agree to the provisions of



                                       10
<PAGE>


this Article 6. Executive agrees that during his employment with Company and for
a period of two (2) years following the termination of Executive's employment
with Company for any reason (the "Non-Solicitation Period"), Executive shall
not:

                  (a) directly or indirectly, either as principal, agent,
         independent contractor, consultant, director, officer, employee,
         employer, advisor, stockholder, partner or in any other individual or
         representative capacity whatsoever, either for his own benefit or for
         the benefit of any other person or entity either (i) hire, contract or
         solicit, or attempt any of the foregoing, with respect to hiring any
         employee of Company or its Affiliates, or (ii) induce or otherwise
         counsel, advise, or encourage any employee of Company or its Affiliates
         to leave the employment of Company or its affiliates;

                  (b) directly or indirectly, either as principal, agent,
         independent contractor, consultant, director, officer, employee,
         employer, advisor, stockholder, partner or in any other individual or
         representative capacity whatsoever, either for his own benefit or for
         the benefit of any other person or entity call upon, solicit, divert,
         or take away any customer or vendor of Company or its Affiliates with
         whom Executive dealt, directly or indirectly, during his engagement
         with Company or its Affiliates, in connection with any business in any
         of the business territories in which Company is presently or from
         time-to-time conducting business that either conducts a business
         substantially similar to that conducted by Company or its Affiliates or
         provides or sells a service or product that is the same, substantially
         similar to or otherwise competitive with the products and services
         provided or sold by Company or its Affiliates (a "COMPETITIVE
         OPERATION"); or

                  (c) call upon any prospective acquisition candidate on
         Executive's own behalf or on behalf of any Competitive Operation, which
         candidate is a Competitive Operation or which candidate was, to
         Executive's knowledge after due inquiry, either called upon by Company
         or for which Company or any of its Affiliates made an acquisition
         analysis, for the purpose of acquiring such entity.

         6.2 NON-DISPARAGEMENT. During Executive's employment with Company and
following any termination of employment with Company, each of Company and
Executive agree not to disparage, either orally or in writing, the other, or any
of the business, products, services or practices of the Company, or any of their
directors, officers, agents, representatives, stockholders, employees or
Affiliates.

         6.3 REMEDIES. Executive acknowledges that money damages would not be
sufficient remedy for any breach of this Article 6 by Executive, and Company or
its Affiliates shall be entitled to enforce the provisions of this Article 6 by
terminating payments then owing to Executive under this Agreement or otherwise
and to specific performance and injunctive relief as remedies for such breach or
any threatened breach. Such remedies shall not be deemed the exclusive remedies
for a breach of this Article 6 but shall be in addition to all remedies
available at law or in equity, including the recovery of damages from Executive
and his agents.

6.4 REFORMATION. Company and Executive agree that the foregoing restrictions are
reasonable under the circumstances and that any breach of the covenants
contained in this Article 6 would cause irreparable injury to Company. Executive
understands that the foregoing



                                       11
<PAGE>


restrictions may limit Executive's ability to engage in certain businesses
anywhere in the United States during the Non-Solicitation Period but
acknowledges that Executive will receive sufficiently high remuneration and
other benefits from Company to justify such restriction. Further, Executive
acknowledges that his skills are such that he can be gainfully employed in
non-competitive employment, and that the agreement not to solicit will in no way
prevent him from earning a living. Nevertheless, if any of the aforesaid
restrictions are found by a court of competent jurisdiction to be unreasonable,
overly broad as to geographic area or time, or otherwise unenforceable, the
parties intend for the restrictions therein set forth to be modified by the
court making such determination so as to be reasonable and enforceable and, as
so modified, to be fully enforced. By agreeing to this contractual modification
prospectively at this time, Company and Executive intend to make this provision
enforceable under the law or laws of all applicable States so that the entire
agreement not to solicit and this Agreement as prospectively modified shall
remain in full force and effect and shall not be rendered void or illegal. Such
modification shall not affect the payments made to Executive under this
Agreement.

ARTICLE 7: MISCELLANEOUS

         7.1 INDEMNIFICATION. If Executive shall obtain any money judgment or
otherwise prevail with respect to any litigation brought by Executive or Company
to enforce or interpret any provision contained herein, Company, to the fullest
extent permitted by applicable law, hereby indemnifies Executive for his
reasonable attorneys' fees and disbursements incurred in such litigation and
hereby agrees (i) to pay in full all such fees and disbursements and (ii) to pay
prejudgment interest on any money judgment obtained by Executive from the
earliest date that payment to him should have been made under this Agreement
until such judgment shall have been paid in full, which interest shall be
calculated at 2% plus the prime or base rate of interest announced by JPMorgan
Chase Bank (or any successor thereto) at its principal office in New York, and
shall change when and as any such change in such prime or base rate shall be
announced by such bank.

         7.2 PAYMENT OBLIGATIONS ABSOLUTE. Company's obligation to pay (or cause
one of its subsidiaries to pay) Executive the amounts and to make the
arrangements provided herein shall be absolute and unconditional and shall not
be affected by any circumstances, including, without limitation, any set-off,
counterclaim, recoupment, defense, or other right which Company (including its
subsidiaries) may have against him or anyone else. All amounts payable by
Company (including its subsidiaries hereunder) shall be paid without notice or
demand. Executive shall not be obligated to seek other employment in mitigation
of the amounts payable or arrangements made under any provision of this
Agreement, and, except as provided in Section 5.3(c) hereof, the obtaining of
any such other employment shall in no event effect any reduction of Company's
obligations to make (or cause to be made) the payments and arrangements required
to be made under this Agreement.

         7.3 NOTICES. For purposes of this Agreement, notices and all other
communications provided for herein shall be in writing and shall be deemed to

                                RELEASE AGREEMENT


         This Release Agreement (this "Agreement") constitutes the release
referred to in that certain Employment Agreement (the "Employment Agreement")
dated as of August 3, 2005, by and between Tom Stoelk ("Executive") and Superior
Well Services, Inc. (the "Company").

For good and valuable consideration, including the Company's provision of
certain payments and benefits to Executive in accordance with Section 5.2 or 5.3
of the Employment Agreement, Executive hereby releases, discharges and forever
acquits the Company, its Affiliates and the past, present and future
stockholders, members, partners, directors, managers, employees, agents,
attorneys, heirs, legal representatives, successors and assigns of the
foregoing, in their personal and representative capacities (collectively, the
"Company Parties"), from liability for, and hereby waives, any and all claims,
damages, or causes of action of any kind related to Executive's employment with
any Company Party, the termination of such employment, and any other acts or
omissions related to any matter on or prior to the date of this Agreement
including without limitation any alleged violation through the date of this
Agreement of: (i) the Age Discrimination in Employment Act of 1967, as amended;
(ii) Title VII of the Civil Rights Act of 1964, as amended; (iii) the Civil
Rights Act of 1991; (iv) Section 1981 through 1988 of Title 42 of the United
States Code, as amended; (v) the Employee Retirement Income Security Act of

and (xxii) any claim for compensation or benefits of any kind not expressly set
forth in the Employment Agreement or any such incentive equity or stock option
agreement (collectively, the "Released Claims"). This Agreement is not intended
to indicate that any such claims exist or that, if they do exist, they are
meritorious. Rather, Executive is simply agreeing that, in exchange for the
consideration recited in the first sentence of this paragraph, any and all
potential claims of this nature that Executive may have against the Company
Parties, regardless of whether they actually exist, are expressly settled,
compromised, and waived. By signing this Agreement, Executive is bound by it.
Anyone who succeeds to Executive's rights and responsibilities, such as heirs or
the executor of Executive's estate, is also bound by this Agreement. This
release also applies to any claims brought by any person or agency or class



                                       15
<PAGE>


action under which Executive may have a right or benefit. THIS RELEASE INCLUDES
MATTERS ATTRIBUTABLE TO THE SOLE OR PARTIAL NEGLIGENCE (WHETHER GROSS OR SIMPLE)
OR OTHER FAULT, INCLUDING STRICT LIABILITY, OF ANY OF THE COMPANY PARTIES.

         Executive affirms that he has not filed, caused to be filed, and
presently is not a party to, any claim, complaint, or action against Employer in
any forum or form. Executive further affirms that he has been paid and/or has
received all leave (paid or unpaid), compensation, wages, bonuses, commissions,
and/or benefits to which he may be entitled and that no other leave (paid or
unpaid), compensation, wages, bonuses, commissions, and/or benefits are due to
him, except as provided in the Employment Agreement. Executive furthermore
affirms that he has no known workplace injuries or occupational diseases and has
been provided and/or has not been denied any leave requested under the Family
and Medical Leave Act of 1993. Executive agrees not to bring or join any lawsuit
against any of the Company Parties in any court relating to any of the Released
Claims. Executive represents that Executive has not brought or joined any
lawsuit or filed any charge or claim against any of the Company Parties in any
court or before any government agency and has made no assignment of any rights
Executive has asserted or may have against any of the Company Parties to any
person or entity, in each case, with respect to any Released Claims. If
Executive brings or joins any lawsuit against any of the Company Parties in any
court (except as necessary to protect Executive's rights under this release or
with respect to Executive's entry into this release) relating to any of the
Released Claims, and Executive is the prevailing party in such lawsuit,
Executive shall be obligated to return to the Company all amounts paid to
Executive under this release, to the extent permitted under applicable law and
ordered by the court. Further, if Executive violates the covenant not to sue set
forth in this paragraph, Executive shall be required to pay all costs and
expenses (including the reasonable fees of counsel, related disbursements of
counsel and court costs) incurred by any Company Party to defend such lawsuit or
other claim.

         Agreement before the execution and delivery hereof to the Company;

                  (c) Executive has been and hereby is advised in writing that
         Executive may, at Executive's option, discuss this Agreement with an
         attorney of Executive's choice and that Executive has had adequate
         opportunity to do so; and

                  (d) Executive fully understands the final and binding effect
         of this Agreement; the only promises made to Executive to sign this
         Agreement are those stated in the Employment Agreement and herein; and
         Executive is signing this Agreement voluntarily and of Executive's own
         free will, and that Executive understands and agrees to each of the
         terms of this Agreement.
