FORM OF 
 INDEMNIFICATION
AGREEMENT 
 THIS INDEMNIFICATION AGREEMENT (the “Agreement”) is made and entered into as of
                    , 2016 by and between Mammoth Energy Services, Inc., a Delaware corporation (the “Company”), and
                     (“Indemnitee”). 

WITNESSETH THAT: 
 WHEREAS,
highly competent persons have become more reluctant to serve as directors or officers or in other capacities for corporations unless they are provided with insurance or indemnification that adequately protects them from the inordinate risk of claims
and actions against them arising out of their service to and activities on behalf of such corporations; 
 WHEREAS, the Board of Directors
of the Company (the “Board”) has determined that the increased difficulty in attracting and retaining such persons is detrimental to the best interests of the Company and that the Company should act to assure such persons
that there will be increased certainty of such protection in the future; 
 WHEREAS, the Board has determined that, in order to attract and
retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. 

WHEREAS, the Amended and Restated Certificate of Incorporation of the Company (the “Certificate of Incorporation”) and
the Bylaws of the Company (as amended, the “Bylaws”), provide for the indemnification of the directors and officers of the Company, as well as persons serving in various other capacities, to the fullest extent permitted by
law, and state that these indemnification provisions are in addition to any other rights to which an indemnitee may be entitled under any other agreement; 

WHEREAS, Indemnitee does not regard the protections available under the Bylaws and the Company’s insurance as adequate in the present
circumstances, and may not be willing to serve or continue to serve as an officer or director of the Company and its subsidiaries without adequate protection, and the Company desires Indemnitee to serve in such capacity; 

WHEREAS, it is reasonable, prudent and necessary for the Company to contractually obligate itself to indemnify, and to advance expenses on
behalf of, Indemnitee to the fullest extent permitted by applicable law so that Indemnitee will serve or continue to serve the Company and its subsidiaries free from undue concern that they will not be so indemnified; 

WHEREAS, Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company and its
subsidiaries on the condition that Indemnitee be so indemnified; and 
 WHEREAS, this Agreement is a supplement to and in furtherance of the
Bylaws and Certificate of Incorporation of the Company and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 

 NOW, THEREFORE, in consideration of Indemnitee’s agreement to serve or continue to serve as
an officer and/or director of the Company or its subsidiaries from and after the date hereof, the parties hereto agree as follows: 
 1.
Indemnity of Indemnitee. The Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest extent permitted by law, as such may be amended from time to time. In furtherance of the foregoing indemnification, and without
limiting the generality thereof: 
 (a) Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall
be entitled to the rights of indemnification provided in this Section 1(a) if, by reason of Indemnitee’s Covered Status (as hereinafter defined), Indemnitee is, or is threatened to be made, a party to or participant in
any Proceeding (as hereinafter defined) other than a Proceeding by or in the right of the Company, which is governed by Section 1(b). Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses (as
hereinafter defined), judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee, or on Indemnitee’s behalf, in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee
acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, as applicable, and with respect to any criminal Proceeding, had no reasonable cause to believe the Indemnitee’s
conduct was unlawful. 
 (b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of
indemnification provided in this Section 1(b) if, by reason of Indemnitee’s Covered Status, Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the
Company. Pursuant to this Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee, or on Indemnitee’s behalf, in connection with such Proceeding if
Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, if applicable law so provides, no indemnification against such Expenses shall be made in
respect of any claim, issue or matter in such Proceeding as to which Indemnitee shall have been adjudged to be liable to the Company, unless and to the extent that the Court of Chancery of the State of Delaware shall determine that such
indemnification may be made. 
 (c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding
any other provision of this Agreement, to the extent that Indemnitee is, by reason of Indemnitee’s Covered Status, a party to and is successful, on the merits or otherwise, in any Proceeding, Indemnitee shall be indemnified to the maximum
extent permitted by law, as such may be amended from time to time, against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. If Indemnitee is not wholly successful in such
Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or
on Indemnitee’s behalf in connection with each successfully resolved claim, issue or matter. For purposes of this Section 1(c) and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal,
with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 

  
 2 

 (d) Indemnification of Appointing Stockholder. If (i) Indemnitee is or was
affiliated with one or more entities that has invested in the Company (each, an “Appointing Stockholder”), and (ii) the Appointing Stockholder is, or is threatened to be made, a party to or a participant in any Proceeding
relating to or arising by reason of Appointing Stockholder’s position as a stockholder of, or lender to, the Company, or Appointing Stockholder’s appointment of or affiliation with Indemnitee or any other director, including without
limitation any alleged misappropriation of a Company asset or corporate opportunity, any claim of misappropriation or infringement of intellectual property relating to the Company, any alleged false or misleading statement or omission made by the
Company (or on its behalf) or its employees or agents, or any allegation of inappropriate control or influence over the Company or its Board members, officers, equity holders or debt holders, then the Appointing Stockholder will be entitled to
indemnification hereunder for Expenses to the same extent as Indemnitee, and the terms of this Agreement as they relate to procedures for indemnification of Indemnitee and advancement of Expenses shall apply to any such indemnification of Appointing
Stockholder. The rights provided to the Appointing Stockholder under this Section 1(c) shall (i) be suspended during any period during which the Appointing Stockholder does not have a representative on the Company’s Board and (ii)
terminate on an initial public offering of the Company’s Common Stock; provided, however, that in the event of any such suspension or termination, the Appointing Stockholder’s rights to indemnification will not be suspended or terminated
with respect to any Proceeding based in whole or in part on facts and circumstances occurring at any time prior to such suspension or termination regardless of whether the Proceeding arises before or after such suspension or termination. The Company
and Indemnitee agree that the Appointing Stockholder is an express third party beneficiary of the terms of this Section 1(c). 
 2.
Additional Indemnity. In addition to, and without regard to any limitations on, the indemnification provided for in Section 1, the Company shall and hereby does indemnify and hold harmless Indemnitee against all Expenses,
judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf if, by reason of Indemnitee’s Covered Status, Indemnitee is, or is threatened to be made, a party to or
participant in any Proceeding (including a Proceeding by or in the right of the Company), including, without limitation, all liability arising out of the negligence or active or passive wrongdoing of Indemnitee. The only limitation that shall
exist upon the Company’s obligations pursuant to this Agreement shall be that the Company shall not be obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in
Sections 6 and 7) to be unlawful. 
 3. Contribution. 

(a) Whether or not the indemnification provided in Sections 1 and 2 is available, in respect of any Proceeding in which the
Company is jointly liable with Indemnitee (or would be if joined in such Proceeding), the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such Proceeding without requiring Indemnitee to contribute to such
payment and the Company hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Company shall not enter into any settlement of any Proceeding in which the Company is jointly liable with Indemnitee (or would
be if joined in such Proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee. 

  
 3 

 (b) Without diminishing or impairing the obligations of the Company set forth in Section
3(a), if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding), the
Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company and all officers,
directors or employees of the Company or the Covered Entities other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such Proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction or
events from which such Proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the Company and all
officers, directors or employees of the Company or the Covered Entities other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such Proceeding), on the one hand, and Indemnitee, on the other hand, in connection with
the transaction or events that resulted in such Expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which applicable law may require to be considered. The relative fault of the Company and all
officers, directors or employees of the Company or the Covered Entities, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such Proceeding), on the one hand, and Indemnitee, on the other hand, shall be
determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary and the degree to which their conduct is
active or passive. 
 (c) The Company hereby agrees to fully indemnify and hold Indemnitee harmless from any claims of contribution which
may be brought by officers, directors or employees of the Company or the Covered Entities, other than Indemnitee, who may be jointly liable with Indemnitee. 

(d) To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to
Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for
Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits
received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and the directors, officers, employees and agents of the Company or the Covered
Entities) and Indemnitee in connection with such event(s) and/or transaction(s). 
 4. Indemnification for Expenses of a
Witness. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of Indemnitee’s Covered Status, a witness, or is made (or asked) to respond to discovery requests, in any Proceeding to which
Indemnitee is not a party, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 

5. Advancement of Expenses. Notwithstanding any other provision of this Agreement, the Company shall advance all Expenses incurred
by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Covered Status within 30 days after 

  
 4 

 
the receipt by the Company of a statement or statements from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such
Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee and shall include or be preceded or accompanied by a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it
shall ultimately be determined that Indemnitee is not entitled to be indemnified against such Expenses. Any advances and undertakings to repay pursuant to this Section 5 shall be unsecured and interest free. 

6. Procedures and Presumptions for Determination of Entitlement to Indemnification. It is the intent of this Agreement to secure
for Indemnitee rights of indemnity that are as favorable as may be permitted under the Bylaws or the General Corporation Law of the State of Delaware and public policy of the State of Delaware. Accordingly, the parties agree that the following
procedures and presumptions shall apply in the event of any question as to whether Indemnitee is entitled to indemnification under this Agreement: 

(a) To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith
such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification. The Secretary of the Company shall, promptly upon receipt
of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. Notwithstanding the foregoing, any failure of Indemnitee to provide such a request to the Company, or to provide such a request in
a timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee unless, and to the extent that, such failure actually and materially prejudices the interests of the Company. 

(b) Upon written request by Indemnitee for indemnification pursuant to the first sentence of Section 6(a), a determination with
respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following five methods, which, except for the fourth method in the event of a Change of Control as defined in Section 13, shall be at the
election of the Board: (1) by a majority vote of the Disinterested Directors, even though less than a quorum, (2) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a
quorum, (3) if there are no Disinterested Directors or if the Disinterested Directors so direct, by Independent Counsel (as hereinafter defined) in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee, (4) in the
event of a Change of Control, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee or (5) if so directed by the Board, by the stockholders of the Company. 

(c) If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 6(b), the
Independent Counsel shall be selected as provided in this Section 6(c). The Independent Counsel shall be selected by the Board, and the Company shall give written notice to Indemnitee advising Indemnitee of the identity of the
Independent Counsel so selected. Indemnitee may, within 10 days after such written notice of selection shall have been given, deliver to the Company a written objection to such selection; provided, however, that such objection may be asserted
only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 13, and the objection shall set forth with particularity the factual basis of
such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If 

  
 5 

 
such written objection is made and substantiated, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that
such objection is without merit. If, within 20 days after submission by Indemnitee of a written request for indemnification pursuant to Section 6(a), no Independent Counsel shall have been selected and not objected to, either the Company
or Indemnitee may petition the Court of Chancery of the State of Delaware or other court of competent jurisdiction for resolution of any objection which shall have been made by Indemnitee to the Company’s selection of Independent Counsel and/or
for the appointment as Independent Counsel of a person selected by the court or by such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent
Counsel under Section 6(b). The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to Section 6(b), and the Company shall pay
all reasonable fees and expenses incident to the procedures of this Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed. 

(d) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such
determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing
evidence. Neither the failure of the Company (including the Disinterested Directors, a committee of such directors or Independent Counsel) to have made a determination, prior to the commencement of any action pursuant to this Agreement, that
indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by the Disinterested Directors, a committee of such directors or Independent Counsel)
that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(e) Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the
Enterprise (as hereinafter defined), including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or
records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Enterprise. In addition, the knowledge and/or actions, or failure to act, of
any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. Whether or not the foregoing provisions of this Section 6(e) are
satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. Anyone seeking to overcome this
presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 
 (f) If the person, persons or
entity empowered or selected under Section 6 to determine whether Indemnitee is entitled to indemnification shall not have made a determination within 60 days after receipt by the Company of the request therefor, the requisite determination
of entitlement to indemnification shall be deemed to have been made and Indemnitee shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make
Indemnitee’s statement not 

  
 6 

 
materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day period may be
extended for a reasonable time, not to exceed an additional 30 days, if the person, persons or entity making such determination with respect to entitlement to indemnification in good faith requires such additional time to obtain or evaluate
documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 6(f) shall not apply if the determination of entitlement to indemnification is to be made by the stockholders pursuant to
Section 6(b) of this Agreement and if (A) within 15 days after receipt by the Company of the request for such determination, the Board or the Disinterested Directors, if appropriate, resolve to submit such determination to the stockholders
for their consideration at an annual meeting thereof to be held within 75 days after such receipt and such determination is made thereat, or (B) a special meeting of stockholders is called within 15 days after such receipt for the purpose of making
such determination, such meeting is held for such purpose within 60 days after having been so called and such determination is made thereat. 

(g) Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to
indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee
and reasonably necessary to such determination. Any Independent Counsel or member of the Board shall act reasonably and in good faith in making a determination regarding the Indemnitee’s entitlement to indemnification under this
Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the
determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 

(h) The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a party to avoid
expense, delay, distraction, disruption and uncertainty. In the event that any Proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without limitation, settlement of
such Proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise in such Proceeding. Anyone seeking to overcome this presumption shall have the burden
of proof and the burden of persuasion by clear and convincing evidence. 
 (i) The termination of any Proceeding or of any claim, issue or
matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to
indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, or, with respect to any criminal Proceeding, that
Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful.

 7. Remedies of Indemnitee. 

(a) In the event that (i) a determination is made pursuant to Section 6 that Indemnitee is not entitled to indemnification under this
Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to indemnification is made pursuant to Section 6(b) within 90 days after receipt by the
Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to this Agreement within 10 days after receipt by the Company of a written request therefor or (v) payment of indemnification is not made within 10
days after a determination has been made that Indemnitee is entitled to indemnification or such determination is deemed to have been made pursuant to Section 6, Indemnitee shall be entitled to an adjudication in an appropriate court of the
State of Delaware, or in any other court of competent jurisdiction, of Indemnitee’s entitlement to such indemnification. Indemnitee shall commence such proceeding seeking an adjudication within 180 days following the date on which
Indemnitee first has the right to commence such proceeding pursuant to this Section 7(a). The Company shall not oppose Indemnitee’s right to seek any such adjudication. 

(b) In the event that a determination shall have been made pursuant to Section 6(b) that Indemnitee is not entitled to
indemnification, any judicial proceeding commenced pursuant to this Section 7 shall be conducted in all respects as a de novo trial on the merits, and Indemnitee shall not be prejudiced by reason of the adverse determination under Section
6(b). 
 (c) If a determination shall have been made pursuant to Section 6(b) that Indemnitee is entitled to indemnification,
the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this Section 7, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make
Indemnitee’s misstatement not materially misleading in connection with the application for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d) In the event that Indemnitee, pursuant to this Section 7, seeks a judicial adjudication of Indemnitee’s rights under, or to
recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies maintained by the Company, the Company shall pay on Indemnitee’s behalf, in advance, any and all expenses (of
the types described in the definition of “Expenses” in Section 13 of this Agreement) actually and reasonably incurred by Indemnitee in such judicial adjudication, regardless of whether Indemnitee ultimately is determined to be
entitled to such indemnification, advancement of expenses or insurance recovery. 
 (e) The Company shall be precluded from asserting in
any judicial proceeding commenced pursuant to this Section 7 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all the provisions
of this Agreement. The Company shall indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within 10 days after receipt by the Company of a written request therefore) advance, to the extent not prohibited by
applicable law, such expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advancement of Expenses from the Company under this Agreement or under any directors’ and
officers’ liability insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be. 

  
 8 

 (f) Notwithstanding anything in this Agreement to the contrary, no determination as to
entitlement to indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding. 
 8.
Non-Exclusivity; Survival of Rights; Insurance; Subrogation; Primacy of Indemnification. 
 (a) The rights of indemnification as
provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, under the Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders, a
resolution of the Board or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee
in Indemnitee’s Covered Status prior to such amendment, alteration or repeal. To the extent that an amendment or modification of the Certificate of Incorporation or Bylaws, whether by law, amendment or otherwise, or an amendment to
Delaware law permits greater indemnification than would be afforded currently under the Certificate of Incorporation, the Bylaws and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater
benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 

(b) To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers,
employees, agents or fiduciaries of the Company or the Covered Entities, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any director, officer,
employee, agent or fiduciary under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has directors’ and officers’ liability insurance in effect, the Company shall
give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of the Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies. 
 (c)
Except as provided in Section 8(f), in the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee who shall execute all papers required and take
all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 

(d) Except as provided in Section 8(f), the Company shall not be liable under this Agreement to make any payment of amounts otherwise
indemnifiable hereunder (or for which advancement is provided hereunder) if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 

  
 9 

 (e) Except as provided in Section 8(f), the Company’s obligation to indemnify or
advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be
reduced by any amount Indemnitee has actually received as indemnification or advancement of Expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. 

(f) Notwithstanding anything set forth to the contrary in this Agreement including, without limitation, Sections 8(c), 8(d) and
8(e) above, the Company hereby acknowledges and agrees that in the event the Indemnitee has certain rights to indemnification, advancement of expenses and/or insurance provided by the Original Stockholder Indemnitors, (i) the Company is the
indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Original Stockholder Indemnitors to advance Expenses or to provide indemnification for the same Expenses or Losses, as defined in Section
13, incurred by Indemnitee are secondary), (ii) the Company shall be required to advance the full amount of Expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses and Losses as required by the terms of this
Agreement and the Certificate of Incorporation or the Bylaws (or any other agreement between the Company and Indemnitee), without regard to any rights such Indemnitee may have against the Original Stockholder Indemnitors, and (iii) the Company
irrevocably waives, relinquishes and releases the Original Stockholder Indemnitors from any and all claims against the Original Stockholder Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company
further agrees that no advancement or payment by the Original Stockholder Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Original
Stockholder Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Original
Stockholder Indemnitors are express third party beneficiaries of the terms of this Section 8. 
 9. Exception to Right of
Indemnification. Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnity in connection with any claim made against Indemnitee: 

(a) for which payment has actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except
with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision, provided, that the foregoing shall not affect the rights of Indemnitee or the Original Stockholder Indemnitors set forth in Section
8(f); or 
 (b) for (i) an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of
the Company within the meaning of Section 16(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or similar provisions of state statutory law or common law or (ii) any reimbursement of the Company
by Indemnitee of any bonus or other incentive-based or equity-based compensation or of any profits realized by Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such reimbursements
that arise from an accounting restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002, as amended (the “Sarbanes-Oxley Act”), or the payment to the Company of profits arising from the
purchase and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act); or

 (c) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee,
including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board authorized the Proceeding (or any such part of any Proceeding)
prior to its initiation or (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law. 

10. Duration of Agreement. All agreements and obligations of the Company contained herein shall continue for so long as Indemnitee
may have any liability or potential liability by virtue of serving as an officer or director of the Company or the Covered Entities and shall continue thereafter so long as Indemnitee shall be subject to any Proceeding (or any proceeding commenced
under Section 7) by reason of Indemnitee’s Covered Status, whether or not Indemnitee is acting or serving in any such capacity at the time any liability or Expense is incurred for which indemnification can be provided under this
Agreement. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation or otherwise to
all or substantially all of the business or assets of the Company), assigns, spouses, heirs, executors and personal and legal representatives. 

11. Security. To the extent requested by Indemnitee and approved by the Board, the Company may at any time and from time to time

prior written consent of Indemnitee.

order to induce Indemnitee to serve as an officer or director of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as an officer or director of the Company. 

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in furtherance of the Certificate of Incorporation,
the Bylaws and applicable law, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 

(c) The Company shall not seek from a court, or agree to, a “bar order” which would have the effect of prohibiting or limiting the
Indemnitee’s rights to receive advancement of Expenses under this Agreement.

invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other provision. Further, the invalidity or unenforceability of any provision hereof as to either Indemnitee or Appointing
Stockholder shall in no way affect the validity or enforceability of any provision hereof as to the other. Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee indemnification rights to the
fullest extent permitted by applicable laws. In the event any provision hereof conflicts with any applicable law, such provision shall be deemed modified, consistent with the aforementioned intent, to the extent necessary to resolve such
conflict.

Section 8. Miscellaneous. 

8.1. Except as expressly provided in this Amendment, (i) the Credit Agreement shall continue in full force and effect, and (ii) the
terms and conditions of the Credit Agreement are expressly incorporated herein and ratified and confirmed in all respects. This Amendment is not intended to be or to create, nor shall it be construed as, a novation or an accord and satisfaction.
From and after the First Amendment Effective Date, references to the Credit Agreement in each Other Document shall be references to the Amended Credit Agreement. The Lenders party hereto hereby direct and instruct Administrative Agent to execute and
deliver this Amendment and all documents to be executed in connection herewith, and to induce Administrative Agent to execute and deliver this Amendment and the other applicable documents, each Lender ratifies and confirms its obligations under, and
the immunities and exculpatory provisions accruing to the Agent under, the terms of the Credit Agreement and the Other Documents and agrees that, as of the First Amendment Effective Date, such obligations, immunities and other provisions are without
setoff, counterclaim, defense or recoupment. This Amendment shall constitute an Other Document. 
 8.2. Each Borrower hereby ratifies and
confirms the Liens and security interests granted under the Credit Agreement and the Other Documents and further ratifies and agrees that such Liens and security interests secure all obligations and indebtedness now, hereafter or from time to time
made by, owing to or arising in favor of the Agent or Lenders pursuant to the Credit Agreement and the Other Documents (as now, hereafter or from time to time amended). 

8.3. This Amendment constitutes the entire agreement among the parties hereto with respect to the subject matter hereof. Neither this
Amendment nor any provision hereof may be changed, waived, discharged, modified or terminated orally, but only by an instrument in writing signed by the parties required to be a party thereto pursuant to the Credit Agreement.

 8.4. This Amendment may be executed in any number of counterparts (including by facsimile or as
a .pdf attachment), and by the different parties hereto on the same or separate counterparts, each of which shall be deemed to be an original instrument but all of which together shall constitute one and the same agreement. 

8.5. If any term or provision of this Amendment is adjudicated to be invalid under applicable laws or regulations, such provision shall be
inapplicable to the extent of such invalidity without affecting the validity or enforceability of the remainder of this Amendment which shall be given effect so far as possible. 

8.6. THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AMENDMENT SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH THE CHOICE OF LAW PROVISIONS SET FORTH IN THE CREDIT AGREEMENT AND SHALL BE SUBJECT TO ANY WAIVER OF JURY TRIAL (OR IF APPLICABLE, THE JUDICIAL REFEREE PROVISIONS) AND NOTICE PROVISIONS OF THE CREDIT AGREEMENT. 

8.7. This Amendment shall be binding upon and inure to the benefit of each Borrower, the Agent and Lenders and their respective successors
and assigns, except that, other than as permitted under Section 7.1 of the Credit Agreement, no Borrower shall have the right to assign any rights hereunder or any interest herein without the Agent’s and the required Lenders’ prior
written consent. Except as provided in the preceding sentence and except as to the ability of the Releasees to rely upon Section 9 hereof (with each being an intended third-party beneficiary of the applicable provisions), no Person shall
be entitled to any third-party beneficiary status or other rights under this Amendment. 
 Section 9. General Release; Covenant
not to Sue. 
 9.1. In consideration of, among other things, Agent’s and the Lenders’ execution and delivery of this
Amendment, each Borrower, on behalf of itself and its respective agents, representatives, officers, directors, advisors, employees, subsidiaries, affiliates, successors and assigns (collectively, “Releasors”), hereby forever waives,
releases and discharges, to the fullest extent permitted by law, each Releasee (as hereinafter defined) from any and all claims (including, without limitation, crossclaims, counterclaims, rights of set-off and recoupment), actions, causes of action,
suits, debts, accounts, interests, liens, promises, warranties, damages and consequential damages, demands, agreements, bonds, bills, specialties, covenants, controversies, variances, trespasses, judgments, executions, costs, expenses or claims
whatsoever (collectively, the “Claims”), that such Releasor now has, of whatsoever nature and kind, whether known or unknown, now existing, whether arising at law or in equity, against any or all of any Agent or any or all of the
Lenders in any capacity and their respective affiliates, subsidiaries, shareholders and “controlling persons” (within the meaning of the federal securities laws), and their respective successors and assigns and each and all of the
officers, directors, employees, agents, attorneys and other representatives of each of the foregoing (collectively, the “Releasees”), based in whole or in part on facts, whether or not now known, existing on or before the date
hereof, that relate to, arise out of or otherwise are in connection with: (i) the Credit Agreement and any or all Other Documents or transactions contemplated thereby or any actions or omissions in connection therewith, (ii) any aspect of
the dealings or relationships between or among the Borrowers, on the one hand, and any or all of the Releasees, on the other hand, relating to any or all of the documents, transactions, actions or omissions referenced in clause (i) hereof, or
(iii) any aspect of the dealings or relationships between or among any or all of Releasors, on the one hand, and the Releasees, on the other hand, but only to the extent such dealings or relationships relate to any or all of the documents,
transactions, actions or omissions referenced in clause (i) hereof. In entering into this Amendment, each

Borrower consulted with, and has been represented by, legal counsel and expressly disclaims any reliance on any representations, acts or omissions by any of the Releasees and hereby agrees and
acknowledges that the validity and effectiveness of the releases set forth above do not depend in any way on any such representations, acts and/or omissions or the accuracy, completeness or validity hereof. The provisions of this
Section 9 shall survive the termination of this Amendment, the Credit Agreement, the Other Documents and payment in full of the Obligations. 

9.2. Each Borrower, on behalf of itself and its successors, assigns, and other legal representatives, hereby absolutely, unconditionally and
irrevocably, covenants and agrees with and in favor of each Releasee that it will not sue (at law, in equity, in any regulatory proceeding or otherwise) any Releasee on the basis of any Claim released, remised and discharged by the Borrowers
pursuant to Section 9.1 hereof. If any Borrower or any of their respective successors, assigns or other legal representatives violates the foregoing covenant, each Borrower, each for itself and its successors, assigns and legal
representatives, agrees to pay, in addition to such other damages as any Releasee may sustain as a result of such violation, all reasonable and documented attorneys’ fees and costs incurred by any Releasee as a result of such violation. 

9.3. The foregoing release shall apply to all unknown or unanticipated results of any events occurring prior to the time this Amendment is
signed, as well as those known or anticipated. Each Borrower understands that the facts in respect of which the foregoing release is given may hereafter turn out to be different from the facts now known or believed to be true. Each Borrower hereby
accepts and assumes the risk that those facts may ultimately be found to be different, and agrees that the foregoing Release shall be in all respects effective, and not subject to termination or rescission by virtue of any such factual differences.

such financial statements, certificates and/or other information, at which time the rate will be adjusted based upon the Excess Availability reflected in such statements. Any increase in interest rates payable by Borrowers under this Agreement and
the Other Documents pursuant to the provisions of the foregoing sentence shall be in addition to and independent of any increase in such interest rates resulting from the occurrence of any Event of Default (including, if applicable, any Event of

[Mammoth] Credit Agreement 

 If, as a result of any restatement of, or other adjustment to, the financial statements of
Borrowers on a Consolidated Basis or for any other reason, Agent reasonably determines that (a) the Excess Availability as previously calculated as of any applicable date for any applicable period was inaccurate, and (b) a proper
calculation of the Excess Availability for any such period would have resulted in different pricing for such period, then (i) if the proper calculation of the Excess Availability would have resulted in a higher interest rate for such period,
automatically and immediately without the necessity of any demand or notice by Agent or any other affirmative act of any party, the interest accrued on the applicable outstanding Advances for such period under the provisions of this Agreement and
the Other Documents shall be deemed to be retroactively increased by, and Borrowers shall be obligated to immediately pay to Agent for the ratable benefit of Lenders an amount equal to the excess of the amount of interest that should have been paid
for such period over the amount of interest actually paid for such period; and (ii) if the proper calculation of the Excess Availability would have resulted in a lower interest rate for such period, then the interest accrued on the applicable
outstanding Advances for such period under the provisions of this Agreement and the Other Documents shall be deemed to remain unchanged, and Agent and Lenders shall have no obligation to repay interest to the Borrowers; provided, that, if as a
result of any restatement or other event or other determination by Agent a proper calculation of the Excess Availability would have resulted in a higher interest rate for one or more periods and a lower interest rate for one or more other periods
(due to the shifting of income or expenses from one period to another period or any other reason), then the amount payable by Borrowers pursuant to clause (i) above shall be based upon the excess, if any, of the amount of interest that should
have been paid for all applicable periods over the amounts of interest actually paid for such periods. 
 “Application
Date” shall have the meaning set forth in Section 2.8(b) hereof. 
 “Approved Electronic
Communication” shall mean each notice, demand, communication, information, document and other material transmitted, posted or otherwise made or communicated by e-mail, E-Fax, the StuckyNet

	II.	ADVANCES, PAYMENTS. 

 2.1. Revolving Advances. 

(a) Amount of Revolving Advances. Subject to the terms and conditions set forth in this Agreement specifically including
Section 2.1(a) below regarding Sand Tiger and Section 2.1(b), each Lender, severally and not jointly, will make Revolving Advances to Borrowers in aggregate amounts outstanding at any time equal to such Lender’s
Commitment Percentage of the lesser of (x) the Maximum Revolving Advance Amount, less the outstanding amount of Swing Loans, less the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit or (y) an amount
equal to the sum of: 
 (i) up to eighty-five percent (85%) (the “Receivables Advance Rate”) of Eligible Receivables,
plus 
 (ii) up to the lesser of (A) up to eighty-five percent (85%), subject to the provisions of Section 2.1(b), of
Eligible Unbilled Receivables or (B) $10,000,000 (“Unbilled Receivables Advance Rate”); plus 
 (iii) up to
the lesser of (A) up to seventy-five percent (75%), subject to the provisions of Section 2.1(b) hereof (the “Sand Inventory Advance Rate”), of the value of Eligible Inventory, (B) up to eighty-five percent
(85%), subject to the provisions of Section 2.1(b) hereof (the “NOLV Advance Rate”), of the net orderly liquidation value percentage (as evidenced by the most recent appraisal accepted by Agent in its Permitted
Discretion, each, an “NOLV Appraisal”) of Eligible Inventory, or (C) $10,000,000 less amounts included in the calculation of the Formula Amount attributable to clause iv below; plus 

  
 49 

[Mammoth] Credit Agreement 

 (iv) the lowest of (A) the Sand Inventory Advance Rate of the value of Eligible In-Transit
Inventory, (B) the NOLV Advance Rate of the net orderly liquidation value percentage (as evidenced by the most recent NOLV Appraisal) of Eligible In-Transit Inventory or (C) $10,000,000 less amounts included in the calculation of the
Formula Amount attributable to clause iii above; plus 
 (v) up to the least of (A) up to eighty percent (80%) (the
“Equipment Advance Rate”, and together with the Receivables Advance Rate, the Sand Inventory Advance Rate, the NOLV Advance Rate, the Equipment Advance Rate
and the Unbilled Receivables Advance Rate, the “Advance Rates”) of the appraised net orderly liquidation value percentage of Eligible Equipment as set forth in the NOLV
Appraisal most recently accepted by Agent, (B) the Eligible Equipment Sublimit or (C) up to eighty percent (80%) of the Maximum Revolving Advance Amount; minus 

(vi) the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit, minus 

(vii) such reserves as Agent may reasonably deem proper and necessary from time to time in the exercise of its Permitted Discretion,
including in respect of Priority Payables relating to Sand Tiger. 
 The amount derived from the sum of (x) Sections
2.1(a)(y)(i), (ii), (iii), (iv) and (v) minus (y) Sections 2.1 (a)(y)(vi) and (vii) at any time and from time to time shall be referred to as the “Formula
Amount”. Notwithstanding the foregoing, the parties agree that not more than $15,000,000 of the proceeds of direct Revolving Advances may be made available and remain outstanding on any day during the Term to Sand Tiger and which value of

(collectively, the “Revolving Credit Note”) substantially in the form attached hereto as Exhibit 2.1(a). Notwithstanding anything to the contrary contained in the foregoing or otherwise in this Agreement, the outstanding
aggregate principal amount of Swing Loans and the Revolving Advances at any one time outstanding shall not exceed an amount equal to the lesser of (i) the Maximum Revolving Advance Amount less the Maximum Undrawn Amount of all outstanding
Letters of Credit or (ii) the Formula Amount. 
 (b) Discretionary Rights. The Advance Rates may be increased or decreased by
Agent at any time and from time to time in the exercise of its Permitted Discretion. Each Borrower consents to any such increases or decreases and acknowledges that decreasing the Advance Rates or increasing or imposing reserves may limit or
restrict Advances requested by Borrowing Agent. Prior to the occurrence and continuance of an Event of Default or Default, Agent shall give Borrowing Agent five (5) days prior written notice of its intention to decrease the Advance Rates. The
rights of Agent under this subsection are subject to the provisions of Section 16.2(b). 

  
 50 

[Mammoth] Credit Agreement 

 2.2. Procedures for Requesting Revolving Advances; Procedures for Selection of Applicable
Interest Rates for All Advances. 
 (a) Borrowing Agent on behalf of any Borrower may notify Agent prior to 1:00 p.m. on a Business Day
of a Borrower’s request to incur, on that day, a Revolving Advance hereunder. Should any amount required to be paid as interest hereunder, or as fees or other charges under this Agreement or any other agreement with Agent or Lenders, or with
respect to any other Obligation under this Agreement, become due, same shall be deemed a request for a Revolving Advance maintained as a Domestic Rate Loan as of the date such payment is due, in the amount required to pay in full such interest, fee,
charge or Obligation, and such request shall be irrevocable. 
 (b) Notwithstanding the provisions of subsection (a) above, in the
event any Borrower desires to obtain a LIBOR Rate Loan for any Advance (other than a Swing Loan), Borrowing Agent shall give Agent written notice by no later than 1:00 p.m. on the day which is three (3) Business Days prior to the date such
LIBOR Rate Loan is to be borrowed, specifying (i) the date of the proposed borrowing (which shall be a Business Day), (ii) the type of borrowing and the amount of such Advance to be borrowed, which amount shall be in a minimum amount of
$500,000 and in integral multiples of $100,000 thereafter, and (iii) the duration of the first Interest Period therefor. Interest Periods for LIBOR Rate Loans shall be for one (1), two (2), three (3) or six (6) months; provided that,
if an Interest Period would end on a day that is not a Business Day, it shall end on the next succeeding Business Day unless such day falls in the next succeeding calendar month in which case the Interest Period shall end on the next preceding
Business Day. No LIBOR Rate Loan shall be made available to any Borrower during the continuance of a Default or an Event of Default. After giving effect to each requested LIBOR Rate Loan, including those which are converted from a Domestic Rate Loan
under Section 2.2(e), there shall not be outstanding more than six (6) LIBOR Rate Loans, in the aggregate. 
 (c) Each
Period of a LIBOR Rate Loan shall commence on the date such LIBOR Rate Loan is made and shall end on such date as Borrowing Agent may elect as set forth in subsection (b)(iii) above, provided that the exact length of each Interest Period
shall be determined in accordance with the practice of the interbank market for offshore Dollar deposits and no Interest Period shall end after the last day of the Term. 

(d) Borrowing Agent shall elect the initial Interest Period applicable to a LIBOR Rate Loan by its notice of borrowing given to Agent pursuant
to Section 2.2(b) or by its notice of conversion given to Agent pursuant to Section 2.2(e), as the case may be. Borrowing Agent shall elect the duration of each succeeding Interest Period by giving irrevocable written notice to Agent of
such duration not later than 1:00 p.m. on the day which is three (3) Business Days prior to the last day of the then current Interest Period applicable to such LIBOR Rate Loan. If Agent does not receive timely notice of the Interest Period
elected by Borrowing Agent, Borrowing Agent shall be deemed to have elected to convert such LIBOR Rate Loan to a Domestic Rate Loan subject to Section 2.2(e) below. 

(e) Provided that no Default or Event of Default shall have occurred and be continuing, Borrowing Agent may, on the last Business Day of the
then current Interest Period applicable to any outstanding LIBOR Rate Loan, or on any Business Day with respect to Domestic Rate Loans, convert any such loan into a loan of another type in the same aggregate principal amount provided that any
conversion of a LIBOR Rate Loan shall be made only on the last Business Day of the then current Interest Period applicable to such LIBOR Rate Loan. If 

  
 51 

[Mammoth] Credit Agreement 

 
Borrowing Agent desires to convert a loan, Borrowing Agent shall give Agent written notice by no later than 1:00 p.m. (i) on the day which is three (3) Business Days prior to the date
on which such conversion is to occur with respect to a conversion from a Domestic Rate Loan to a LIBOR Rate Loan, or (ii) on the day which is one (1) Business Day prior to the date on which such conversion is to occur (which date shall be
the last Business Day of the Interest Period for the applicable LIBOR Rate Loan) with respect to a conversion from a LIBOR Rate Loan to a Domestic Rate Loan, specifying, in each case, the date of such conversion, the loans to be converted and if the
conversion is to a LIBOR Rate Loan, the duration of the first Interest Period therefor. 
 (f) At its option and upon written notice given
prior to 1:00 p.m. at least three (3) Business Days prior to the date of such prepayment, any Borrower (other than Sand Tiger) may, subject to Section 2.2(g) hereof, prepay the LIBOR Rate Loans in whole at any time or in part from time to
time with accrued interest on the principal being prepaid to the date of such repayment. Such Borrower shall specify the date of prepayment of Advances which are LIBOR Rate Loans and the amount of such prepayment. In the event that any prepayment of
a LIBOR Rate Loan is required or permitted on a date other than the last Business Day of the then current Interest Period with respect thereto, such Borrower shall indemnify Agent and Lenders therefor in accordance with Section 2.2(g) hereof.

 (g) Each Borrower (other than Sand Tiger) shall indemnify Agent and Lenders and hold Agent and Lenders harmless from and against any and
all losses or expenses that Agent and Lenders may sustain or incur as a consequence of any prepayment, conversion of or any default by any Borrower (other than Sand Tiger) in the payment of the principal of or interest on any LIBOR Rate Loan or
failure by any such Borrower to complete a borrowing of, a prepayment of or conversion of or to a LIBOR Rate Loan after notice thereof has been given, including, but not limited to, any interest payable by Agent or Lenders to lenders of funds
obtained by it in order to make or maintain its LIBOR Rate Loans hereunder. A certificate as to any additional amounts payable pursuant to the foregoing sentence submitted by Agent or any Lender to Borrowing Agent shall be conclusive absent manifest
error. 
 (h) Notwithstanding any other provision hereof, if any Applicable Law, treaty, regulation or directive, or any change therein or
in the interpretation or application thereof, including without limitation any Change in Law, shall make it unlawful for Lenders or any Lender (for purposes of this subsection (h), the term “Lender” shall include any Lender and the
office or branch where any Lender or any Person controlling such Lender makes or maintains any LIBOR Rate Loans) to make or maintain its LIBOR Rate Loans, the obligation of Lenders (or such affected Lender) to make LIBOR Rate Loans hereunder shall
forthwith be cancelled and Borrowers shall, if any affected LIBOR Rate Loans are then outstanding, promptly upon request from Agent, either pay all such affected LIBOR Rate Loans or convert such affected LIBOR Rate Loans into loans of another type.
If any such payment or conversion of any LIBOR Rate Loan is made on a day that is not the last day of the Interest Period applicable to such LIBOR Rate Loan, Borrowers shall pay Agent, upon Agent’s request, such amount or amounts set forth in
clause (g) above. A certificate as to any additional amounts payable pursuant to the foregoing sentence submitted by Lenders to Borrowing Agent shall be conclusive absent manifest error. 

  
 52 

[Mammoth] Credit Agreement 

 2.3. [Reserved]  

2.4. Swing Loans. 
 (a)
Subject to the terms and conditions set forth in this Agreement, and in order to minimize the transfer of funds between Lenders and Agent for administrative convenience, Agent, Lenders holding Commitments and Swing Loan Lender agree that in order to
facilitate the administration of this Agreement, Swing Loan Lender may, at its election and option made in its sole discretion cancelable at any time for any reason whatsoever, make swing loan advances (“Swing Loans”) available to
Borrowers as provided for in this Section 2.4 at any time or from time to time after the date hereof to, but not including, the expiration of the Term, in an aggregate principal amount up to but not in excess of the Maximum Swing Loan Advance
Amount, provided that the outstanding aggregate principal amount of Swing Loans and the Revolving Advances at any one time outstanding shall not exceed an amount equal to the lesser of (i) the Maximum Revolving Advance Amount less the Maximum
Undrawn Amount of all outstanding Letters of Credit or (ii) the Formula Amount and shall be subject to the sublimits in Section 2.1(a). All Swing Loans shall be Domestic Rate Loans only. Borrowers may borrow (at the option and
election of Swing Loan Lender), repay and reborrow (at the option and election of Swing Loan Lender) Swing Loans and Swing Loan Lender may make Swing Loans as provided in this Section 2.4 during the period between Settlement Dates. All Swing
Loans shall be evidenced by a secured promissory note (the “Swing Loan Note”) substantially in the form attached hereto as Exhibit 2.4(a). Swing Loan Lender’s agreement to make Swing Loans under this Agreement is cancelable at
any time for any reason whatsoever and the making of Swing Loans by Swing Loan Lender from time to time shall not create any duty or obligation, or establish any course of conduct, pursuant to which Swing Loan Lender shall thereafter be obligated to
make Swing Loans in the future 
 (b) Upon either (i) any request by Borrowing Agent for a Revolving Advance made pursuant to
Section 2.2(a) hereof or (ii) the occurrence of any deemed request by Borrowers for a Revolving Advance pursuant to the provisions of the last sentence of Section 2.2(a) hereof, Swing Loan Lender may elect, in its sole discretion, to
have such request or deemed request treated as a request for a Swing Loan, and may advance same day funds to Borrowers as a Swing Loan; provided that notwithstanding anything to the contrary provided for herein, Swing Loan Lender may not make Swing
Loan Advances if Swing Loan Lender has been notified by Agent or by Required Lenders that one or more of the applicable conditions set forth in Section 8.2 of this Agreement have not been satisfied or the Commitments have been terminated for
any reason. 
 (c) Upon the making of a Swing Loan (whether before or after the occurrence of a Default or an Event of Default and
regardless of whether a Settlement has been requested with respect to such Swing Loan), each Lender holding a Commitment shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from Swing Loan
Lender, without recourse or warranty, an undivided interest and participation in such Swing Loan in proportion to its Commitment Percentage. Swing Loan Lender or Agent may, at any time, require the Lenders holding Commitments to fund such
participations by means of a Settlement as provided for in Section 2.6(d) below. From and after the date, if any, on which any Lender holding a Commitment is required to fund, and funds, its participation in any Swing Loans purchased hereunder,
Agent shall promptly distribute to such Lender its Commitment Percentage of all 

  
 53 

[Mammoth] Credit Agreement 

 
payments of principal and interest and all proceeds of Collateral received by Agent in respect of such Swing Loan; provided that no Lender holding a Commitment shall be obligated in any event to
make Revolving Advances in an amount in excess of its Commitment Amount minus its Participation Commitment (taking into account any reallocations under Section 2.22) of the Maximum Undrawn Amount of all outstanding Letters of Credit. 

2.5. Disbursement of Advance Proceeds. All Advances shall be disbursed from whichever office or other place Agent may designate from
time to time and, together with any and all other Obligations of Borrowers to Agent or Lenders, shall be charged to Borrowers’ Account or Sand Tiger’s Account, as applicable, on Agent’s books. The proceeds of each Revolving Advance or
Swing Loan requested by Borrowing Agent on behalf of any Borrower or deemed to have been requested by any Borrower under Sections 2.2(a), 2.6(b) or 2.14 hereof shall, (i) with respect to requested Revolving Advances, to the extent Lenders make
such Revolving Advances in accordance with Section 2.2(a), 2.6(b) or 2.14 hereof, and with respect to Swing Loans made upon any request by Borrowing Agent for a Revolving Advance to the extent Swing Loan Lender makes such Swing Loan in
accordance with Section 2.4(b) hereof, be made available to the applicable Borrower on the day so requested by way of credit to such Borrower’s operating account at PNC, or such other bank as Borrowing Agent may designate following
notification to Agent, in immediately available federal funds or other immediately available funds or, (ii) with respect to Revolving Advances deemed to have been requested by any Borrower or Swing Loans made upon any deemed request for a
Revolving Advance by any Borrower, be disbursed to Agent to be applied to the outstanding Obligations giving rise to such deemed request. During the Term, Borrowers may use the Revolving Advances and Swing Loans by borrowing, prepaying and
reborrowing, all in accordance with the terms and conditions hereof. 
 2.6. Making and Settlement of Advances. 

(a) Each borrowing of Revolving Advances shall be advanced according to the applicable Commitment Percentages of Lenders holding the
Commitments (subject to any contrary terms of Section 2.22). Each borrowing of Swing Loans shall be advanced by Swing Loan Lender alone. 

(b) Promptly after receipt by Agent of a request or a deemed request for a Revolving Advance pursuant to Section 2.2(a) and, with respect
to Revolving Advances, to the extent Agent elects not to provide a Swing Loan or the making of a Swing Loan would result in the aggregate amount of all outstanding Swing Loans exceeding the maximum amount permitted in Section 2.4(a), Agent
shall notify Lenders holding the Commitments of its receipt of such request specifying the information provided by Borrowing Agent and the apportionment among Lenders of the requested Revolving Advance as determined by Agent in accordance with the
terms hereof. Each Lender shall remit the principal amount of each Revolving Advance to Agent such that Agent is able to, and Agent shall, to the extent the applicable Lenders have made funds available to it for such purpose and subject to
Section 8.2, fund such Revolving Advance to Borrowers in U.S. Dollars and immediately available funds at the Payment Office prior to the close of business, on the applicable borrowing date; provided that if any applicable Lender fails to
remit such funds to Agent in a timely manner, Agent may elect in its sole discretion to fund with its own funds the Revolving Advance of such Lender on such borrowing date, and such Lender shall be subject to the repayment obligation in
Section 2.6(c) hereof. 

  
 54 

[Mammoth] Credit Agreement 

 (c) Unless Agent shall have been notified by telephone, confirmed in writing, by any Lender
holding a Commitment that such Lender will not make the amount which would constitute its applicable Commitment Percentage of the requested Revolving Advance available to Agent, Agent may (but shall not be obligated to) assume that such Lender has
made such amount available to Agent on such date in accordance with Section 2.6(b) and may, in reliance upon such assumption, make available to Borrowers a corresponding amount. Agent will promptly notify Borrowing Agent of its receipt of any
such notice from a Lender. In such event, if a Lender has not in fact made its applicable Commitment Percentage of the requested Revolving Advance available to Agent, then the applicable Lender and Borrowers severally agree to pay to Agent on demand
such corresponding amount with interest thereon, for each day from and including the date such amount is made available to Borrowers through but excluding the date of payment to Agent, at (i) in the case of a payment to be made by such Lender,
the greater of (A) (x) the daily average Federal Funds Effective Rate (computed on the basis of a year of 360 days) during such period as quoted by Agent, times (y) such amount or (B) a rate determined by Agent in accordance with
banking industry rules on interbank compensation, and (ii) in the case of a payment to be made by Borrowers, the Revolving Interest Rate for Revolving Advances that are Domestic Rate Loans. If such Lender pays its share of the applicable
Revolving Advance to Agent, then the amount so paid shall constitute such Lender’s Revolving Advance. Any payment by Borrowers shall be without prejudice to any claim Borrowers may have against a Lender holding a Commitment that shall have
failed to make such payment to Agent. A certificate of Agent submitted to any Lender or Borrowers with respect to any amounts owing under this paragraph (c) shall be conclusive, in the absence of manifest error. 

(d) Agent, on behalf of Swing Loan Lender, shall demand settlement (a “Settlement”) of all or any Swing Loans with Lenders
holding the Commitments on at least a weekly basis, or on any more frequent date that Agent elects or that Swing Loan Lender at its option exercisable for any reason whatsoever may request, by notifying Lenders holding the Commitments of such
requested Settlement by facsimile, telephonic or electronic transmission no later than 3:00 p.m. on the date of such requested Settlement (the “Settlement Date”). Subject to any contrary provisions of Section 2.22, each Lender
holding a Commitment shall transfer the amount of such Lender’s Commitment Percentage of the outstanding principal amount (plus interest accrued thereon to the extent requested by Agent) of the applicable Swing Loan with respect to which
Settlement is requested by Agent, to such account of Agent as Agent may designate not later than 5:00 p.m. on such Settlement Date if requested by Agent by 3:00 p.m., otherwise not later than 5:00 p.m. on the next Business Day. Settlements may occur
at any time notwithstanding that the conditions precedent to making Revolving Advances set forth in Section 8.2 have not been satisfied or the Commitments shall have otherwise been terminated at such time. All amounts so transferred to Agent
shall be applied against the amount of outstanding Swing Loans and, when so applied shall constitute Revolving Advances of such Lenders accruing interest as Domestic Rate Loans. If any such amount is not transferred to Agent by any Lender holding a
Commitment on such Settlement Date, Agent shall be entitled to recover such amount on demand from such Lender together with interest thereon as specified in Section 2.6(c). 

(e) If any Lender or Participant (a “Benefited Lender”) shall at any time receive any payment of all or part of its Advances,
or interest thereon, or receive any Collateral in respect thereof (whether voluntarily or involuntarily or by set-off) in a greater proportion than any such 

  
 55 

[Mammoth] Credit Agreement 

 
payment to and Collateral received by any other Lender, if any, in respect of such other Lender’s Advances, or interest thereon, and such greater proportionate payment or receipt of
Collateral is not expressly permitted hereunder, such Benefited Lender shall purchase for cash from the other Lenders a participation in such portion of each such other Lender’s Advances, or shall provide such other Lender with the benefits of
any such Collateral, or the proceeds thereof, as shall be necessary to cause such Benefited Lender to share the excess payment or benefits of such Collateral or proceeds ratably with each of the other Lenders; provided, however, that if all or any
portion of such excess payment or benefits is thereafter recovered from such Benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. Each Borrower
consents to the foregoing and agrees, to the extent it may effectively do so under Applicable Law, that each Lender so purchasing a portion of another Lender’s Advances may exercise all rights of payment (including rights of set-off) with
respect to such portion as fully as if such Lender were the direct holder of such portion, and the obligations owing to each such purchasing Lender in respect of such participation and such purchased portion of any other Lender’s Advances shall
be part of the Obligations secured by the Collateral, and the obligations owing to each such purchasing Lender in respect of such participation and such purchased portion of any other Lender’s Advances shall be part of the Obligations secured
by the Collateral. 
 2.7. Maximum Advances. The aggregate balance of Revolving Advances plus Swing Loans outstanding at any time
shall not exceed the lesser of (a) the Maximum Revolving Advance Amount less the aggregate Maximum Undrawn Amount of all issued and outstanding Letters of Credit or (b) the Formula Amount. 

2.8. Manner and Repayment of Advances. 

(a) The Revolving Advances and Swing Loans shall be due and payable in full on the last day of the Term subject to earlier prepayment as herein
provided. Notwithstanding the foregoing, all Advances shall be subject to earlier repayment upon (x) acceleration upon the occurrence and continuance of an Event of Default under this Agreement or (y) termination of this Agreement by the
Borrowing Agent. Each payment (including each prepayment) by any Borrower (other than Sand Tiger) on account of the principal of and interest on the Advances shall be applied, first to the outstanding Swing Loans and next, pro rata according to the
applicable Commitment Percentages of Lenders, to the outstanding Advances (subject to any contrary provisions of Section 2.22). Each payment (including each prepayment) by Sand Tiger on account of the principal of and interest on the Advances
in respect of Sand Tiger shall be applied, first to the outstanding Swing Loans made in respect of Sand Tiger and next, pro rata according to the applicable Commitment Percentages of Lenders, to the outstanding Advances made in respect of Sand Tiger
(subject to any contrary provisions of Section 2.22). 
 (b) Each Borrower recognizes that the amounts evidenced by checks,
notes, drafts or any other items of payment relating to and/or proceeds of Collateral may not be collectible by Agent on the date received by Agent. Agent shall conditionally credit Borrowers’ Account for each item of payment on the next
Business Day after the Business Day on which such item of payment is received by Agent (and the Business Day on which each such item of payment is so credited shall be referred to, with respect to such item, as the “Application
Date”). Agent is not, however, required to credit the applicable Borrowers’ Account for the amount of any item of 

  
 56 

[Mammoth] Credit Agreement 

 
payment which is unsatisfactory to Agent and Agent may charge Borrowers’ Account for the amount of any item of payment which is returned, for any reason whatsoever, to Agent unpaid. Subject
to the foregoing, Borrowers agree that for purposes of computing the interest charges under this Agreement, each item of payment received by Agent shall be deemed applied by Agent on account of the Obligations on its respective Application Date. All
proceeds received by Agent during a Trigger Period shall be applied to the Obligations in accordance with Section 4.8(h). 
 (c)
All payments of principal, interest and other amounts payable hereunder, or under any of the Other Documents shall be made to Agent at the Payment Office not later than 1:00 p.m. on the due date therefor in Dollars in federal funds or other funds
immediately available to Agent. Agent shall have the right to effectuate payment of any and all Obligations due and owing hereunder by charging the applicable Borrowers’ Account or by making Advances as provided in Section 2.2 hereof. 

(d) Except as expressly provided herein, all payments (including prepayments) to be made by any Borrower on account of principal, interest,
fees and other amounts payable hereunder shall be made without deduction, setoff or counterclaim and shall be made to Agent on behalf of Lenders to the Payment Office, in each case on or prior to 1:00 p.m., in Dollars and in immediately available
funds. 
 2.9. Repayment of Excess Advances. If at any time the aggregate balance of outstanding Revolving Advances, Swing Loans,
and/or Advances taken as a whole exceeds the maximum amount of such type of Advances and/or Advances taken as a whole (as applicable) permitted hereunder, such excess Advances shall be immediately due and payable without the necessity of any demand,
at the Payment Office, whether or not a Default or an Event of Default has occurred. 
 2.10. Statement of Account. Agent shall
maintain, in accordance with its customary procedures, loan accounts (“Borrowers’ Accounts”), one in the names of Borrowers other than Sand Tiger and one in the name of Sand Tiger for loans made to it, in which shall be
recorded the date and amount of each Advance made by Agent or Lenders and the date and amount of each payment in respect thereof; provided, however, the failure by Agent to record the date and amount of any Advance shall not adversely affect Agent
or any Lender. Each month, Agent shall send to Borrowing Agent a statement showing the accounting for the Advances made, payments made or credited in respect thereof, and other transactions between Agent, Lenders and Borrowers during such month. The
monthly statements shall be deemed correct and binding upon Borrowers in the absence of manifest error and shall constitute an account stated between Lenders and Borrowers unless Agent receives a written statement of Borrowers’ specific
exceptions thereto within thirty (30) days after such statement is received by Borrowing Agent. The records of Agent with respect to the Borrowers’ Accounts shall be conclusive evidence absent manifest error of the amounts of Advances and
other charges thereto and of payments applicable thereto. 
 2.11. Letters of Credit. 

(a) Subject to the terms and conditions hereof, Issuer shall issue or cause the issuance of standby and/or trade letters of credit denominated
in Dollars (“Letters of Credit”) for the account of any Borrower except to the extent that the issuance thereof would then cause the 

  
 57 

[Mammoth] Credit Agreement 

 
sum of (i) the outstanding Revolving Advances plus (ii) the outstanding Swing Loans, plus (iii) the Maximum Undrawn Amount of all outstanding Letters of Credit, plus (iv) the
Maximum Undrawn Amount of the Letter of Credit to be issued to exceed the lesser of (x) the Maximum Revolving Advance Amount or (y) the Formula Amount (calculated without giving effect to the deductions provided for in
Section 2.1(a)(y)(vi)). The Maximum Undrawn Amount of all outstanding Letters of Credit shall not exceed in the aggregate at any time the Letter of Credit Sublimit. All disbursements or payments related to Letters of Credit shall be
deemed to be Domestic Rate Loans consisting of Revolving Advances and shall bear interest at the Revolving Interest Rate for Domestic Rate Loans. Letters of Credit that have not been drawn upon shall not bear interest (but fees shall accrue in
respect of outstanding Letters of Credit as provided in Section 3.2 hereof). 
 (b) Notwithstanding any provision of this Agreement,
Issuer shall not be under any obligation to issue any Letter of Credit if (i) any order, judgment or decree of any Governmental Body or arbitrator shall by its terms purport to enjoin or restrain Issuer from issuing any Letter of Credit, or any
Law applicable to Issuer or any request or directive (whether or not having the force of law) from any Governmental Body with jurisdiction over Issuer shall prohibit, or request that Issuer refrain from, the issuance of letters of credit generally
or the Letter of Credit in particular or shall impose upon Issuer with respect to the Letter of Credit any restriction, reserve or capital requirement (for which Issuer is not otherwise compensated hereunder) not in effect on the date of this
Agreement, or shall impose upon Issuer any unreimbursed loss, cost or expense which was not applicable on the date of this Agreement, and which Issuer in good faith deems material to it, or (ii) the issuance of the Letter of Credit would
violate one or more policies of Issuer applicable to letters of credit generally. 
 2.12. Issuance of Letters of Credit. 

(a) Borrowing Agent, on behalf of any Borrower, may request Issuer to issue or cause the issuance of a Letter of Credit by delivering to
Issuer, with a copy to Agent at the Payment Office, prior to 1:00 p.m., at least five (5) Business Days prior to the proposed date of issuance, such Issuer’s form of Letter of Credit Application (the “Letter of Credit
Application”) completed to the satisfaction of Agent and Issuer; and, such other certificates, documents and other papers and information as Agent or Issuer may reasonably request. Issuer shall not issue any requested Letter of Credit if
such Issuer has received notice from Agent or any Lender that one or more of the applicable conditions set forth in Section 8.2 of this Agreement have not been satisfied or the commitments of Lenders to make Revolving Advances hereunder have
been terminated for any reason. 
 (b) Each Letter of Credit shall, among other things, (i) provide for the payment of sight drafts,
other written demands for payment, or acceptances of usance drafts when presented for honor thereunder in accordance with the terms thereof and when accompanied by the documents described therein and (ii) have an expiry date not later than
twelve (12) months after such Letter of Credit’s date of issuance and any automatic renewals thereof and in no event later than the last day of the Term. Each standby Letter of Credit shall be subject either to the Uniform Customs and
Practice for Documentary Credits as most recently published by the International Chamber of Commerce at the time a Letter of Credit is issued (the “UCP”) or the International Standby Practices (ISP98-International Chamber of
Commerce Publication Number 590) (the “ISP98 Rules”), or any subsequent revision thereof at the time a standby Letter of Credit is issued, 

  
 58 

[Mammoth] Credit Agreement 

 
as determined by Issuer, and each trade Letter of Credit shall be subject to the UCP. In addition, no trade Letter of Credit may permit the presentation of an ocean bill of lading that includes a
condition that the original bill of lading is not required to claim the goods shipped thereunder. 
 (c) Agent shall use its reasonable
efforts to notify Lenders of the request by Borrowing Agent for a Letter of Credit hereunder. 
 2.13. Requirements For Issuance of
Letters of Credit. 
 (a) Borrowing Agent shall authorize and direct any Issuer to name the applicable Borrower as the
“Applicant” or “Account Party” of each Letter of Credit. If Agent is not the Issuer of any Letter of Credit, Borrowing Agent shall authorize and direct the Issuer to deliver to Agent all instruments, documents, and other writings
and property received by the Issuer pursuant to the Letter of Credit and to accept and rely upon Agent’s instructions and agreements with respect to all matters arising in connection with the Letter of Credit or the application therefor. 

(b) In connection with all trade Letters of Credit issued or caused to be issued by Issuer under this Agreement, each Borrower hereby appoints
Issuer, or its designee, as its attorney, with full power and authority if an Event of Default shall have occurred and continues: (i) to sign and/or endorse such Borrower’s name upon any warehouse or other receipts, and acceptances;
(ii) to sign such Borrower’s name on bills of lading; (iii) to clear Inventory through the United States of America Customs Department or Canada Border Services Agency, as applicable, (“Customs”) in the name of such
Borrower or Issuer or Issuer’s designee, and to sign and deliver to Customs officials powers of attorney in the name of such Borrower for such purpose; and (iv) to complete in such Borrower’s name or Issuer’s, or in the name of
Issuer’s designee, any order, sale or transaction, obtain the necessary documents in connection therewith, and collect the proceeds thereof. Neither Agent, Issuer nor their attorneys will be liable for any acts or omissions nor for any error of
judgment or mistakes of fact or law, except for Agent’s, Issuer’s or their respective attorney’s gross negligence or willful misconduct. This power, being coupled with an interest, is irrevocable as long as any Letters of Credit
remain outstanding. 
 2.14. Disbursements, Reimbursement. 

(a) Immediately upon the issuance of each Letter of Credit, each Lender holding a Commitment shall be deemed to, and hereby irrevocably and
unconditionally agrees to, purchase from Issuer a participation in each Letter of Credit and each drawing thereunder in an amount equal to such Lender’s Commitment Percentage of the Maximum Undrawn Amount of such Letter of Credit (as in effect
from time to time) and the amount of such drawing, respectively. 
 (b) In the event of any request for a drawing under a Letter of Credit
by the beneficiary or transferee thereof, Issuer will promptly notify Agent and Borrowing Agent. Regardless of whether Borrowing Agent shall have received such notice, Borrowers shall reimburse (such obligation to reimburse Issuer shall sometimes be
referred to as a “Reimbursement Obligation”) Issuer prior to 12:00 Noon, on each date that an amount is paid by Issuer under any Letter of Credit (each such date, a “Drawing Date”) in an amount equal to the amount
so paid by Issuer. In the event Borrowers fail to reimburse Issuer for the full amount of 

  
 59 

[Mammoth] Credit Agreement 

 
any drawing under any Letter of Credit by 12:00 Noon, on the Drawing Date, Issuer will promptly notify Agent and each Lender holding a Commitment thereof, and Borrowers shall be automatically
deemed to have requested that a Revolving Advance maintained as a Domestic Rate Loan be made by Lenders to be disbursed on the Drawing Date under such Letter of Credit, and Lenders holding the Commitments shall be unconditionally obligated to fund
such Revolving Advance (all whether or not the conditions specified in Section 8.2 are then satisfied or the commitments of Lenders to make Revolving Advances hereunder have been terminated for any reason) as provided for in
Section 2.14(c) immediately below. Any notice given by Issuer pursuant to this Section 2.14(b) may be oral if promptly confirmed in writing; provided that the lack of such a confirmation shall not affect the conclusiveness or binding
effect of such notice. 
 (c) Each Lender holding a Commitment shall upon any notice pursuant to Section 2.14(b) make available to
Issuer through Agent at the Payment Office an amount in immediately available funds equal to its Commitment Percentage (subject to any contrary provisions of Section 2.22) of the amount of the drawing, whereupon the participating Lenders shall
(subject to Section 2.14(d)) each be deemed to have made a Revolving Advance maintained as a Domestic Rate Loan to Borrowers in that amount. If any Lender holding a Commitment so notified fails to make available to Agent, for the benefit of
Issuer, the amount of such Lender’s Commitment Percentage of such amount by 2:00 p.m. on the Drawing Date, then interest shall accrue on such Lender’s obligation to make such payment, from the Drawing Date to the date on which such Lender
makes such payment (i) at a rate per annum equal to the Federal Funds Effective Rate during the first three (3) days following the Drawing Date and (ii) at a rate per annum equal to the rate applicable to Revolving Advances maintained
as a Domestic Rate Loan on and after the fourth day following the Drawing Date. Agent and Issuer will promptly give notice of the occurrence of the Drawing Date, but failure of Agent or Issuer to give any such notice on the Drawing Date or in
sufficient time to enable any Lender holding a Commitment to effect such payment on such date shall not relieve such Lender from its obligations under this Section 2.14(c), provided that such Lender shall not be obligated to pay interest as
provided in Section 2.14(c)(i) and (ii) until and commencing from the date of receipt of notice from Agent or Issuer of a drawing. 

(d) With respect to any unreimbursed drawing that is not converted into a Revolving Advance maintained as a Domestic Rate Loan to Borrowers in
whole or in part as contemplated by Section 2.14(b), because of Borrowers’ failure to satisfy the conditions set forth in Section 8.2 hereof (other than any notice requirements) or for any other reason, Borrowers shall be deemed to
have incurred from Agent, subject to Section 16.19, a borrowing (each a “Letter of Credit Borrowing”) in the amount of such drawing. Such Letter of Credit Borrowing shall be due and payable on demand (together with
interest) and shall bear interest at the rate per annum applicable to a Revolving Advance maintained as a Domestic Rate Loan. Each applicable Lender’s payment to Agent pursuant to Section 2.14(c) shall be deemed to be a payment in respect
of its participation in such Letter of Credit Borrowing and shall constitute a “Participation Advance” from such Lender in satisfaction of its Participation Commitment in respect of the applicable Letter of Credit under this
Section 2.14. 
 (e) Each applicable Lender’s Participation Commitment in respect of the Letters of Credit shall continue until
the last to occur of any of the following events: (x) Issuer ceases to be obligated to issue or cause to be issued Letters of Credit hereunder; (y) no Letter of Credit issued or created hereunder remains outstanding and uncancelled; and
(z) all Persons (other than Borrowers) have been fully reimbursed for all payments made under or relating to Letters of Credit. 

  
 60 

[Mammoth] Credit Agreement 

 2.15. Repayment of Participation Advances. 

(a) Upon (and only upon) receipt by Agent for the account of Issuer of immediately available funds from Borrowers (i) in reimbursement of
any payment made by Issuer or Agent under the Letter of Credit with respect to which any Lender has made a Participation Advance to Agent, or (ii) in payment of interest on such a payment made by Issuer or Agent under such a Letter of Credit,
Agent will pay to each Lender holding a Commitment, in the same funds as those received by Agent, the amount of such Lender’s Commitment Percentage of such funds, except Agent shall retain the amount of the Commitment Percentage of such funds
of any Lender holding a Commitment that did not make a Participation Advance in respect of such payment by Agent (and, to the extent that any of the other Lender(s) holding the Commitment have funded any portion such Defaulting Lender’s
Participation Advance in accordance with the provisions of Section 2.22, Agent will pay over to such Non-Defaulting Lenders a pro rata portion of the funds so withheld from such Defaulting Lender). 

(b) If Issuer or Agent is required at any time to return to any Borrower, or to a trustee, receiver, liquidator, monitor, custodian, or any
official in any insolvency proceeding, any portion of the payments made by Borrowers to Issuer or Agent pursuant to Section 2.15(a) in reimbursement of a payment made under the Letter of Credit or interest or fee thereon, each applicable Lender
shall, on demand of Agent, forthwith return to Issuer or Agent the amount of its Commitment Percentage of any amounts so returned by Issuer or Agent plus interest at the Federal Funds Effective Rate. 

2.16. Documentation. Each Borrower agrees to be bound by the terms of the Letter of Credit Application and by Issuer’s
interpretations of any Letter of Credit issued on behalf of such Borrower and by Issuer’s written regulations and customary practices relating to letters of credit, though Issuer’s interpretations may be different from such Borrower’s
own. In the event of a conflict between the Letter of Credit Application and this Agreement, this Agreement shall govern. It is understood and agreed that, except in the case of gross negligence or willful misconduct (as determined by a court of
competent jurisdiction in a final non-appealable judgment), Issuer shall not be liable for any error, negligence and/or mistakes, whether of omission or commission, in following Borrowing Agent’s or any Borrower’s instructions or those
contained in the Letters of Credit or any modifications, amendments or supplements thereto. 
 2.17. Determination to Honor Drawing
Request. In determining whether to honor any request for drawing under any Letter of Credit by the beneficiary thereof, Issuer shall be responsible only to determine that the documents and certificates required to be delivered under such Letter
of Credit have been delivered and that they comply on their face with the requirements of such Letter of Credit and that any other drawing condition appearing on the face of such Letter of Credit has been satisfied in the manner so set forth. 

2.18. Nature of Participation and Reimbursement Obligations. The obligation of each Lender holding a Commitment in accordance with this
Agreement to make the Revolving 

  
 61 

[Mammoth] Credit Agreement 

 
Advances or Participation Advances as a result of a drawing under a Letter of Credit, and the obligations of Borrowers to reimburse Issuer upon a draw under a Letter of Credit, shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Section 2.18 under all circumstances, including the following circumstances: 

(i) any set-off, counterclaim, recoupment, defense or other right which such Lender or any Borrower, as the case may be, may have against

 (ii) the failure of any
Borrower or any other Person to comply, in connection with a Letter of Credit Borrowing, with the conditions set forth in this Agreement for the making of a Revolving Advance, it being acknowledged that such conditions are not required for the
making of a Letter of Credit Borrowing and the obligation of Lenders to make Participation Advances under Section 2.14; 
 (iii) any
lack of validity or enforceability of any Letter of Credit; 
 (iv) any claim of breach of warranty that might be made by any Borrower,
Agent, Issuer or any Lender against the beneficiary of a Letter of Credit, or the existence of any claim, set-off, recoupment, counterclaim, cross-claim, defense or other right which any Borrower, Agent, Issuer or any Lender may have at any time
against a beneficiary, any successor beneficiary or any transferee of any Letter of Credit or assignee of the proceeds thereof (or any Persons for whom any such transferee or assignee may be acting), Issuer, Agent or any Lender or any other Person,
whether in connection with this Agreement, the transactions contemplated herein or any unrelated transaction (including any underlying transaction between any Borrower or any Subsidiaries of such Borrower and the beneficiary for which any Letter of
Credit was procured); 
 (v) the lack of power or authority of any signer of (or any defect in or forgery of any signature or endorsement
on) or the form of or lack of validity, accuracy, enforceability or genuineness of any draft, demand, instrument, certificate or other document presented under or in connection with any Letter of Credit, or any fraud or alleged fraud in connection
with any Letter of Credit, or the transport of any property or provision of services relating to a Letter of Credit, in each case even if Issuer or any of Issuer’s Affiliates has been notified thereof; 

(vi) payment by Issuer under any Letter of Credit against presentation of a demand, draft or certificate or other document which is forged or
does not fully comply with the terms of such Letter of Credit (provided that the foregoing shall not excuse Issuer from any obligation under the terms of any applicable Letter of Credit to require the presentation of documents that on their face
appear to satisfy any applicable requirements for drawing under such Letter of Credit prior to honoring or paying any such draw); 
 (vii)
the solvency of, or any acts or omissions by, any beneficiary of any Letter of Credit, or any other Person having a role in any transaction or obligation relating to a Letter of Credit, or the existence, nature, quality, quantity, condition, value
or other characteristic of any property or services relating to a Letter of Credit; 

  
 62 

[Mammoth] Credit Agreement 

 (viii) any failure by Issuer or any of Issuer’s Affiliates to issue any Letter of Credit in
the form requested by Borrowing Agent, unless Agent and Issuer have each received written notice from Borrowing Agent of such failure within three (3) Business Days after Issuer shall have furnished Agent and Borrowing Agent a copy of such
Letter of Credit and such error is material and no drawing has been made thereon prior to receipt of such notice; 
 (ix) the occurrence of
any Material Adverse Effect; 
 (x) any breach of this Agreement or any Other Document by any party thereto; 

(xi) the occurrence or continuance of an insolvency proceeding with respect to any Borrower or any Guarantor; 

(xii) the fact that a Default or an Event of Default shall have occurred and be continuing; and 

(xiii) the fact that the Term shall have expired or this Agreement or the obligations of Lenders to make Advances have been terminated. 

2.19. Liability for Acts and Omissions. 

(a) As between Borrowers and Issuer, Swing Loan Lender, Agent and Lenders, each Borrower assumes all risks of the acts and omissions of, or
misuse of the Letters of Credit by, the respective beneficiaries of such Letters of Credit, other than the gross negligence or willful misconduct of the Agent as determined by a final and non-appealable judgment of a court of competent jurisdiction.
In furtherance and not in limitation of the foregoing, Issuer shall not be responsible for: (i) the form, validity, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for an issuance
of any such Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged (even if Issuer or any of its Affiliates shall have been notified thereof); (ii) the validity or
sufficiency of any instrument transferring or assigning or purporting to transfer or assign any such Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any
reason; (iii) the failure of the beneficiary of any such Letter of Credit, or any other party to which such Letter of Credit may be transferred, to comply fully with any conditions required in order to draw upon such Letter of Credit or any
other claim of any Borrower against any beneficiary of such Letter of Credit, or any such transferee, or any dispute between or among any Borrower and any beneficiary of any Letter of Credit or any such transferee; (iv) errors, omissions,
interruptions or delays in transmission or delivery of any messages, by mail, cable, facsimile, telex or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the
transmission or otherwise of any document required in order to make a drawing under any such Letter of Credit or of the proceeds thereof; (vii) the misapplication by the beneficiary of any such Letter of Credit of the proceeds of any drawing
under such Letter of Credit; or (viii) any consequences arising from causes beyond the control of Issuer, including any Governmental Acts, and none of the above shall affect or impair, or prevent the vesting of, any of Issuer’s rights or
powers hereunder. Nothing in the preceding sentence shall relieve Issuer from liability for Issuer’s gross negligence or willful 

  
 63 

[Mammoth] Credit Agreement 

 
misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment) in connection with actions or omissions described in such clauses (i) through
(viii) of such sentence. In no event shall Issuer or Issuer’s Affiliates be liable to any Borrower for any indirect, consequential, incidental, punitive, exemplary or special damages or expenses (including without limitation
attorneys’ fees), or for any damages resulting from any change in the value of any property relating to a Letter of Credit. 
 (b)
Without limiting the generality of the foregoing, Issuer and each of its Affiliates: (i) may rely on any oral or other communication believed in good faith by Issuer or such Affiliate to have been authorized or given by or on behalf of the
applicant for a Letter of Credit; (ii) may honor any presentation if the documents presented appear on their face substantially to comply with the terms and conditions of the relevant Letter of Credit; (iii) may honor a previously
dishonored presentation under a Letter of Credit, whether such dishonor was pursuant to a court order, to settle or compromise any claim of wrongful dishonor, or otherwise, and shall be entitled to reimbursement to the same extent as if such
presentation had initially been honored, together with any interest paid by Issuer or its Affiliates; (iv) may honor any drawing that is payable upon presentation of a statement advising negotiation or payment, upon receipt of such statement
(even if such statement indicates that a draft or other document is being delivered separately), and shall not be liable for any failure of any such draft or other document to arrive, or to conform in any way with the relevant Letter of Credit;
(v) may pay any paying or negotiating bank claiming that it rightfully honored under the laws or practices of the place where such bank is located; and (vi) may settle or adjust any claim or demand made on Issuer or its Affiliate in any
way related to any order issued at the applicant’s request to an air carrier, a letter of guarantee or of indemnity issued to a steamship agent or carrier or any document or instrument of like import (each an “Order”) and honor
any drawing in connection with any Letter of Credit that is the subject of such Order, notwithstanding that any drafts or other documents presented in connection with such Letter of Credit fail to conform in any way with such Letter of Credit. 

(c) In furtherance and extension and not in limitation of the specific provisions set forth above, any action taken or omitted by Issuer under
or in connection with the Letters of Credit issued by it or any documents and certificates delivered thereunder, if taken or omitted in good faith and without gross negligence (as determined by a court of competent jurisdiction in a final
non-appealable judgment), shall not put Issuer under any resulting liability to any Borrower, Agent or any Lender. 
 2.20. Mandatory
Prepayments. 
 (a) Subject to Section 7.1 hereof, when any Borrower sells or otherwise disposes of any Collateral other than
Inventory in the ordinary course of business or as otherwise permitted under this Agreement, each applicable Borrower shall repay the Advances made for its benefit and/or made directly or indirectly to it in an amount equal to the net proceeds of
such sale (i.e., gross proceeds less the reasonable direct costs of such sales or other dispositions) if such net proceeds are in excess of $1,000,000, such repayments to be made promptly but in no event more than one (1) Business Day following
receipt of such net proceeds, and until the date of payment, such proceeds shall be and shall be deemed to be held in trust exclusively for Agent. The foregoing shall not be deemed to be implied consent to any such sale otherwise prohibited by the
terms and conditions hereof. Such repayments shall be applied to the remaining Advances made 

  
 64 

[Mammoth] Credit Agreement 

 
for its benefit and/or made directly or indirectly to it (including cash collateralization of all Obligations relating to any outstanding Letters of Credit (issued in the case of Sand Tiger on
its behalf only) in accordance with the provisions of Section 3.2(b); provided however that if no Default or Event of Default has occurred and is continuing, such repayments shall be applied to cash collateralize any Obligations related to
outstanding Letters of Credit last) in such order as Agent may determine, subject to Borrowers’ ability to reborrow Revolving Advances in accordance with the terms hereof or (ii) if the Collateral disposed of is equipment other than as set
forth in (i) above or other Collateral, to the remaining Advances made for its benefit and/or made directly or indirectly to it (including cash collateralization of all Obligations relating to any outstanding Letters of Credit in accordance
with the provisions of Section 3.2(b), provided however that if no Default or Event of Default has occurred and is continuing, such repayments shall be applied to cash collateralize any Obligations related to outstanding Letters of Credit last)
in such order as Agent may determine, subject to Borrowers’ ability to reborrow Revolving Advances in accordance with the terms hereof. Any such repayment shall not reduce the Maximum Revolving Advance Amount. 

(b) Upon the consummation of any Qualifiedthe Closing Date IPO, each applicable Borrower shall repay the Advances made for its
benefit and/or made directly or indirectly to it in an amount necessary to cause Borrowers’ Excess Availability to at least equal to $75,000,000 after giving effect to
such repaymentequal to the lesser of (i) the net proceeds of the Closing Date IPO and (ii) an amount
necessary to cause the complete repayment of all outstanding Revolving Advances as of such date, such repayments to be made promptly but in no event more than one (1) Business Day following
receipt of such net proceeds, and until the date of payment, such proceeds shall be held in trust for Agent. Any such repayment shall not reduce the Maximum Revolving Advance Amount. 

(c) During any Trigger Period, in the event of any issuance or other incurrence of Indebtedness (other than Indebtedness described in
clause (i) of the definition of Permitted Indebtedness) by Borrowers, each applicable Borrower shall, no later than one (1) Business Day after the receipt by Borrowers of the cash proceeds from any such issuance or incurrence of
Indebtedness, repay the Advances made for its benefit and/or made directly or indirectly to it in an amount equal to one hundred percent (100%) of such cash proceeds of such incurrence or issuance of Indebtedness. Any such repayment shall not
reduce the Maximum Revolving Advance Amount. 
 (d) During any Trigger Period, all proceeds received by Borrowers or Agent (i) under
any insurance policy on account of damage or destruction of any assets or property of any Borrowers, or (ii) as a result of any taking or condemnation of any assets or property shall be applied in accordance with Section 6.6 hereof.

 2.21. Use of Proceeds. 

(a) Borrowers shall apply the proceeds of Advances to (i) repay existing indebtedness of the Borrowers on the Closing Date, (ii) pay
fees and expenses relating to the Transactions, and (iii) provide for the Borrowers’ general business purposes, including working capital requirements, making Capital Expenditures, making Permitted Acquisitions, making debt payments (but
not prepayments on debt other than Advances) when due and making distributions and dividends, in each case, to the extent not prohibited under this Agreement. 

  
 65 

[Mammoth] Credit Agreement 

 (b) Without limiting the generality of Section 2.21(a) above, neither the Borrowers,
the Guarantors nor any other Person which may in the future become party to this Agreement or the Other Documents as a Borrower or Guarantor, intends to use nor shall they use any portion of the proceeds of the Advances, directly or indirectly, for
any purpose in violation of Applicable Law. 
 2.22. Defaulting Lender. 

(a) Notwithstanding anything to the contrary contained herein, in the event any Lender is a Defaulting Lender, all rights and obligations
hereunder of such Defaulting Lender and of the other parties hereto shall be modified to the extent of the express provisions of this Section 2.22 so long as such Lender is a Defaulting Lender. 

(b) (i) except as otherwise expressly provided for in this Section 2.22, Revolving Advances shall be made pro rata from Lenders holding
Commitments which are not Defaulting Lenders based on their respective Commitment Percentages, and no Commitment Percentage of any Lender or any pro rata share of any Revolving Advances required to be advanced by any Lender shall be increased as a
result of any Lender being a Defaulting Lender. Amounts received in respect of principal of any type of Revolving Advances shall be applied to reduce such type of Revolving Advances of each Lender (other than any Defaulting Lender) holding a
Commitment in accordance with their Commitment Percentages; provided, that, Agent shall not be obligated to transfer to a Defaulting Lender any payments received by Agent for Defaulting Lender’s benefit, nor shall a Defaulting Lender be
entitled to the sharing of any payments hereunder (including any principal, interest or fees). Amounts payable to a Defaulting Lender shall instead be paid to or retained by Agent. Agent may hold and, in its discretion, re-lend to a Borrower the
amount of such payments received or retained by it for the account of such Defaulting Lender. 
 (ii) fees pursuant to Section 3.3
hereof shall cease to accrue in favor of such Defaulting Lender. 
 (iii) if any Swing Loans are outstanding or any Letters of Credit (or
drawings under any Letter of Credit for which Issuer has not been reimbursed) are outstanding or exist at the time any such Lender holding a Commitment becomes a Defaulting Lender, then: 

(A) Defaulting Lender’s Participation Commitment in the outstanding Swing Loans and of the Maximum Undrawn Amount of all outstanding
Letters of Credit shall be reallocated among Non-Defaulting Lenders holding Commitments in proportion to the respective Commitment Percentages of such Non-Defaulting Lenders to the extent (but only to the extent) that (x) such reallocation does
not cause the aggregate sum of outstanding Revolving Advances made by any such Non-Defaulting Lender holding a Commitment plus such Lender’s reallocated Participation Commitment in the outstanding Swing Loans plus such Lender’s reallocated
Participation Commitment in the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit to exceed the Commitment Amount of any such Non-Defaulting Lender, and (y) no Default or Event of Default has occurred and is continuing at
such time; 

  
 66 

[Mammoth] Credit Agreement 

 (B) if the reallocation described in clause (A) above cannot, or can only partially, be
effected, Borrowers shall within one Business Day following notice by Agent (x) first, prepay any outstanding Swing Loans that cannot be reallocated, and (y) second, cash collateralize for the benefit of Issuer, Borrowers’ obligations
corresponding to such Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit (after giving effect to any partial reallocation pursuant to clause (A) above) in accordance with Section 3.2(b)
for so long as such Obligations are outstanding; 
 (C) if Borrowers cash collateralize any portion of such Defaulting Lender’s
Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit pursuant to clause (B) above, Borrowers shall not be required to pay any fees to such Defaulting Lender pursuant to Section 3.2(a) with respect to such
Defaulting Lender’s Commitment Percentage of Maximum Undrawn Amount of all Letters of Credit during the period such Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit are cash
collateralized; 
 (D) if Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit is
reallocated pursuant to clause (A) above, then the fees payable to Lenders holding Commitments pursuant to Section 3.2(a) shall be adjusted and reallocated to Non-Defaulting Lenders holding Commitments in accordance with such reallocation;
and 
 (E) if all or any portion of such Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of
Credit is neither reallocated nor cash collateralized pursuant to clauses (A) or (B) above, then, without prejudice to any rights or remedies of Issuer or any other Lender hereunder, all Letter of Credit Fees payable under
Section 3.2(a) with respect to such Defaulting Lender’s Commitment Percentage of the Maximum Undrawn Amount of all Letters of Credit shall be payable to the Issuer (and not to such Defaulting Lender) until (and then only to the extent
that) such Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit is reallocated and/or cash collateralized; and 

(iv) so long as any Lender holding a Commitment is a Defaulting Lender, Swing Loan Lender shall not be required to fund any Swing Loans and
Issuer shall not be required to issue, amend or increase any Letter of Credit, unless such Issuer is satisfied that the related exposure and Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit and
all Swing Loans (after giving effect to any such issuance, amendment, increase or funding) will be fully allocated to Non-Defaulting Lenders holding Commitments and/or cash collateral for such Letters of Credit will be provided by Borrowers in
accordance with clause (A) and (B) above, and participating interests in any newly made Swing Loan or any newly issued or increased Letter of Credit shall be allocated among Non-Defaulting Lenders in a manner consistent with
Section 2.22(b)(iii)(A) above (and such Defaulting Lender shall not participate therein). 
 (c) A Defaulting Lender shall not be
entitled to give instructions to Agent or to approve, disapprove, consent to or vote on any matters relating to this Agreement and the Other Documents, and all amendments, waivers and other modifications of this Agreement and the Other Documents may
be made without regard to a Defaulting Lender and, for purposes of the definition 

  
 67 

[Mammoth] Credit Agreement 

 
of “Required Lenders”, a Defaulting Lender shall not be deemed to be a Lender, to have any outstanding Advances or a Commitment Percentage provided, that this clause (c) shall not
apply to the vote of a Defaulting Lender in the case of an amendment, waiver or other modification described in clauses (i) or (ii) of Section 16.2(b). 

(d) Other than as expressly set forth in this Section 2.22, the rights and obligations of a Defaulting Lender (including the obligation
to indemnify Agent) and the other parties hereto shall remain unchanged. Nothing in this Section 2.22 shall be deemed to release any Defaulting Lender from its obligations under this Agreement and the Other Documents, shall alter such
obligations, shall operate as a waiver of any default by such Defaulting Lender hereunder, or shall prejudice any rights which any Borrower, Agent or any Lender may have against any Defaulting Lender as a result of any default by such Defaulting
Lender hereunder. 
 (e) In the event that Agent, Borrowers, Swing Loan Lender and Issuer agree in writing that a Defaulting Lender has
adequately remedied all matters that caused such Lender to be a Defaulting Lender, then Agent will so notify the parties hereto, and, if such cured Defaulting Lender is a Lender holding a Commitment, then Participation Commitments of Lenders holding
Commitments (including such cured Defaulting Lender) of the Swing Loans and Maximum Undrawn Amount of all outstanding Letters of Credit shall be reallocated to reflect the inclusion of such Lender’s Commitment, and on such date such Lender
shall purchase at par such of the Revolving Advances of the other Lenders as Agent shall determine may be necessary in order for such Lender to hold such Revolving Advances in accordance with its Commitment Percentage. 

(f) If Swing Loan Lender or Issuer has a good faith belief that any Lender holding a Commitment has defaulted in fulfilling its obligations
under one or more other agreements in which such Lender commits to extend credit, Swing Loan Lender shall not be required to fund any Swing Loans and Issuer shall not be required to issue, amend or increase any Letter of Credit, unless Swing Loan
Lender or Issuer, as the case may be, shall have entered into arrangements with Borrowers or such Lender, satisfactory to Swing Loan Lender or Issuer, as the case may be, to defease any risk to it in respect of such Lender hereunder. 

2.23. Payment of Obligations. Agent may charge to Borrowers’ Account or Sand Tiger’s Account, as applicable, a Revolving
Advance or, at the discretion of Swing Loan Lender, as a Swing Loan (i) all payments with respect to any of the Obligations or Obligations of Sand Tiger, as applicable, required hereunder (including without limitation principal payments,
payments of interest, payments of Letter of Credit Fees and all other fees provided for hereunder and payments under Sections 16.5 and 16.9) as and when each such payment shall become due and payable (whether as regularly scheduled, upon or after
acceleration, upon maturity or otherwise), (ii) without limiting the generality of the foregoing clause (i), (a) all amounts expended by Agent or any Lender pursuant to Sections 4.2 or 4.3 hereof and (b) all respective expenses which
Agent incurs in connection with the forwarding of Advance proceeds and the establishment and maintenance of any Blocked Accounts or Depository Accounts as provided for in Section 4.8(h), and (iii) any sums expended by Agent or any Lender
due to any Borrower’s failure to perform or comply with its obligations under this Agreement or any Other Document including any Borrower’s obligations under Sections 3.3, 3.4, 4.3, 4.6, 6.4, 6.6, 6.7 and 6.8 hereof, and all amounts so
charged shall be added to the Obligations or Obligations of Sand Tiger, as applicable, and shall be secured by the Collateral securing the applicable Obligations. To the extent 

  
 68 

[Mammoth] Credit Agreement 

 
Revolving Advances are not actually funded by the other Lenders in respect of any such amounts so charged, all such amounts so charged shall be deemed to be Revolving Advances made by and owing
to Agent and Agent shall be entitled to all rights (including accrual of interest) and remedies of a Lender under this Agreement and the Other Documents with respect to such Revolving Advances. 

2.24. Increase in Maximum Revolving Advance Amount. 

(a) Borrowers may request that the Maximum Revolving Advance Amount be increased by (1) one or more of the current Lenders increasing
their Commitment Amount (any current Lender which elects to increase its Commitment Amount shall be referred to as an “Increasing Lender”) or (2) one or more new lenders (each a “New Lender”) joining this
Agreement and providing a Commitment Amount hereunder, subject to the following terms and conditions: 
 (i) No current Lender shall be
obligated to increase its Commitment Amount and any increase in the Commitment Amount by any current Lender shall be in the sole discretion of such current Lender; 

(ii) There shall exist no Event of Default or Default on the effective date of such increase after giving effect to such increase; 

(iii) After giving effect to such increase, the Maximum Revolving Advance Amount shall not exceed $250,000,000; 

(iv) Borrowers may not request an increase in the Maximum Revolving Advance Amount under this Section 2.24 more than three
(3) times during the Term, and no single such increase in the Maximum Revolving Advance Amount shall be for an amount less than $20,000,000, and all such increases in the Maximum Revolving Advance Amount shall not exceed $80,000,000 in the
aggregate; 
 (v) Borrowers shall deliver to Agent on or before the effective date of such increase the following documents in form and
substance satisfactory to Agent: (1) certifications of their corporate secretaries with attached resolutions certifying that the increase in the Commitment Amounts has been approved by such Borrowers, (2) certificate dated as of the
effective date of such increase certifying that no Default or Event of Default shall have occurred and be continuing and certifying that the representations and warranties made by each Borrower herein and in the Other Documents are true and correct
in all material respects (or, if such representation and warranty is, by its terms, limited by materiality (including a Material Adverse Effect), then such representation and warranty shall be true in all respects) on and as of such date as if made
on and as of such date (except to the extent any such representation or warranty specifically relates to a certain prior date), (3) such other agreements, instruments and information (including supplements or modifications to this Agreement
and/or the Other Documents executed by Borrowers as Agent reasonably deems necessary in order to document the increase to the Maximum Revolving Advance Amount and to protect, preserve and continue the perfection and priority of the liens, security
interests, rights and remedies of Agent and Lenders hereunder and under the Other Documents in light of such increase, and (4) an opinion of 

  
 69 

[Mammoth] Credit Agreement 

 
counsel in form and substance satisfactory to Agent which shall cover such matters related to such increase as Agent may reasonably require and each Borrower hereby authorizes and directs such
counsel to deliver such opinions to Agent and Lenders; 
 (vi) Borrowers shall execute and deliver (1) to each Increasing Lender a
replacement Note or Notes reflecting the new amount of such Increasing Lender’s Commitment Amount after giving effect to the increase (and the prior Note or Notes issued to such Increasing Lender shall be deemed to be cancelled) and (2) to
each New Lender a Note or Notes reflecting the amount of such New Lender’s Commitment Amount; 
 (vii) Any New Lender shall be subject
to the reasonable satisfaction of the Agent; 
 (viii) Each Increasing Lender shall confirm its agreement to increase its Commitment Amount
pursuant to an acknowledgement in a form reasonably acceptable to Agent, signed by it and each Borrower and delivered to Agent at least five (5) days before the effective date of such increase; and 

(ix) Each New Lender shall execute a lender joinder in substantially the form of Exhibit 2.24 pursuant to which such New Lender shall
join and become a party to this Agreement and the Other Documents with a Commitment Amount as set forth in such lender joinder. 
 (b) On
the effective date of such increase, (i) Borrowers shall repay all Revolving Advances then outstanding, subject to Borrowers’ obligations under Sections 3.7, 3.9, or 3.10; provided that subject to the other conditions
of this Agreement, the Borrowing Agent may request new Revolving Advances on such date and (ii) the Commitment Percentages of Lenders holding a Commitment (including each Increasing Lender and/or New Lender) shall be recalculated such that each
such Lender’s Commitment Percentage is equal to (x) the Commitment Amount of such Lender divided by (y) the aggregate of the Commitment Amounts of all Lenders. Each Lender shall participate in any new Revolving Advances made on
or after such date in accordance with its Commitment Percentage after giving effect to the increase in the Maximum Revolving Advance Amount and recalculation of the Commitment Percentages contemplated by this Section 2.24. 

(c) On the effective date of such increase, each Increasing Lender shall be deemed to have purchased an additional/increased participation in,
and each New Lender will be deemed to have purchased a new participation in, each then outstanding Letter of Credit and each drawing thereunder and each then outstanding Swing Loan in an amount equal to such Lender’s Commitment Percentage (as
calculated pursuant to Section 2.24(b) above) of the Maximum Undrawn Amount of each such Letter of Credit (as in effect from time to time) and the amount of each drawing and of each such Swing Loan, respectively. As necessary to effectuate the
foregoing, each existing Lender holding a Commitment Percentage that is not an Increasing Lender shall be deemed to have sold to each applicable Increasing Lender and/or New Lender, as necessary, a portion of such existing Lender’s
participations in such outstanding Letters of Credit and drawings and such outstanding Swing Loans such that, after giving effect to all such purchases and sales, each Lender holding a Commitment (including each Increasing Lender and/or New

  
 70 

[Mammoth] Credit Agreement 

 
Lender) shall hold a participation in all Letters of Credit (and drawings thereunder) and all Swing Loans in accordance with their respective Commitment Percentages (as calculated pursuant to
Section 2.24(b) above). 
 (d) On the effective date of such increase, Borrowers shall pay all reasonable out-of-pocket costs and
expenses incurred by Agent and by each Increasing Lender and New Lender in connection with the negotiations regarding, and the preparation, negotiation, execution and delivery of all agreements and instruments executed and delivered by any of Agent,
Borrowers and/or Increasing Lenders and New Lenders in connection with, such increase (including all fees for any supplemental or additional public filings of any Other Documents necessary to protect, preserve and continue the perfection and
priority of the liens, security interests, rights and remedies of Agent and Lenders hereunder and under the Other Documents in light of such increase). 

(e) Each of the parties hereto hereby agrees that, upon the effectiveness of any increase to the Commitments provided for under this
Section 2.24, this Agreement shall be amended to the extent (but only to the extent) necessary to reflect the existence of such increase and the Advances provided for in connection therewith, and any such amendment may, without the consent of
the other Lenders, effect such amendments to this Agreement and the Other Documents as may be necessary or appropriate, in the reasonable opinion of the Agent and Borrowers, to effectuate the provisions of this Section 2.24 and, for the
avoidance of doubt, this Section 2.24(e) shall supersede any contrary provisions in Section 16.2. 
 2.25. Reduction of Maximum
Revolving Advance Amount. Borrowing Agent may no more than once during each period of twelve months, on at least three (3) Business Days’ prior written notice received by Agent (which shall promptly advise each Lender thereof)
permanently reduce the Maximum Revolving Advance Amount, minimum increments of $10,000,000 to an amount not less than the amount of the then outstanding Advances. All reductions of the Maximum Revolving Advance Amount shall be applied ratably among
the Lenders according to their respective Commitment Amounts. For the avoidance of doubt, voluntary prepayments on the unutilized portion of the Maximum Revolving Advance Amount coupled with any permanent reduction of the Maximum Revolving Advance
Amount effected pursuant to the immediately preceding sentence will be subject to (x) payment of (i) if such permanent reduction is effective prior to the first anniversary of the Closing Date, fees contemplated in Section 13.1
hereof and (ii) breakage costs in the case of a prepayment of LIBOR Rate Loans other than on the last day of the relevant Interest Period, and (y) any other provisions contained in this Agreement. 

 

	III.	INTEREST AND FEES. 

 3.1. Interest. Interest on Advances shall be payable in arrears on
the first day of each month with respect to Domestic Rate Loans and, with respect to LIBOR Rate Loans, at (a) the end of each Interest Period or (b) for LIBOR Rate Loans with an interest period in excess of three months, at the end of each
three month period during such Interest Period, provided further that all accrued and unpaid interest shall be due and payable at the end of the Term. Interest charges shall be computed on the actual principal amount of Advances outstanding during
the month at a rate per annum equal to (i) with respect to Revolving Advances, the Revolving Interest Rate and (ii) with respect to Swing Loans, the Revolving Interest Rate for Domestic Rate Loans. Except as

  
 71 

[Mammoth] Credit Agreement 

 
expressly provided otherwise in this Agreement, any Obligations other than the Advances that are not paid when due shall accrue interest at the Revolving Interest Rate for Domestic Rate Loans,
subject to the provision of the final sentence of this Section 3.1 regarding the Default Rate. Whenever, subsequent to the date of this Agreement, the Alternate Base Rate is increased or decreased, the Revolving Interest Rate for Domestic Rate
Loans shall be similarly changed without notice or demand of any kind by an amount equal to the amount of such change in the Alternate Base Rate during the time such change or changes remain in effect. The LIBOR Rate shall be adjusted with respect
to LIBOR Rate Loans without notice or demand of any kind on the effective date of any change in the Reserve Percentage as of such effective date. Upon and after the occurrence of an Event of Default, and during the continuation thereof, at the
option of Agent or at the direction of Required Lenders (or, in the case of any Event of Default under Section 10.7, immediately and automatically upon the occurrence of any such Event of Default without the requirement of any affirmative
action by any party), the Obligations shall bear interest at the applicable Revolving Interest Rate plus two percent (2%) per annum (the “Default Rate”). 

3.2. Letter of Credit Fees. 

(a) Each applicable Borrower shall pay (x) to Agent, for the ratable benefit of Lenders holding Commitments, fees for each Letter of
Credit for the period from and excluding the date of issuance of same to and including the date of expiration or termination, equal to the average daily face amount of each outstanding Letter of Credit multiplied by the Applicable Margin for
Revolving Advances consisting of LIBOR Rate Loans, such fees to be calculated on the basis of a 360-day year for the actual number of days elapsed and to be payable quarterly in arrears on the first day of each calendar quarter and on the last day
of the Term, and (y) to Issuer, a fronting fee of one quarter of one percent (0.25%) per annum times the average daily face amount of each outstanding Letter of Credit for the period from and excluding the date of issuance of same to and
including the date of expiration or termination, to be payable quarterly in arrears on the first day of each calendar quarter and on the last day of the Term. (all of the foregoing fees, the “Letter of Credit Fees”). In addition,
Borrowers shall pay to Agent, for the benefit of Issuer, any and all applicable administrative, issuance, amendment, payment and negotiation charges with respect to Letters of Credit and all fees and expenses as agreed upon by Issuer and the
Borrowing Agent in connection with any Letter of Credit, including in connection with the opening, amendment or renewal of any such Letter of Credit and any acceptances created thereunder, all such charges, fees and expenses, if any, to be payable
on demand. All such charges shall be deemed earned in full on the date when the same are due and payable hereunder and shall not be subject to rebate or pro-ration upon the termination of this Agreement for any reason. Any such charge in effect at
the time of a particular transaction shall be the charge for that transaction, notwithstanding any subsequent change in Issuer’s prevailing charges for that type of transaction. Upon and after the occurrence of an Event of Default, and during
the continuation thereof, at the option of Agent or at the direction of Required Lenders (or, in the case of any Event of Default under Section 10.7, immediately and automatically upon the occurrence of any such Event of Default without the
requirement of any affirmative action by any party), the Letter of Credit Fees described in clause (x) of this Section 3.2(a) shall be increased by an additional two percent (2.0%) per annum. 

(b) At any time following the occurrence and during the continuance of an Event of Default, at the option of Agent or at the direction of
Required Lenders (or, in the case of 

  
 72 

[Mammoth] Credit Agreement 

 
any Event of Default under Section 10.7, immediately and automatically upon the occurrence of such Event of Default, without the requirement of any affirmative action by any party), or upon
the expiration of the Term or any other termination of this Agreement (and also, if applicable, in connection with any mandatory prepayment under Section 2.20), Borrowers will cause cash to be deposited and maintained in an account with Agent,
as cash collateral, in an amount equal to one hundred and five percent (105%) of the Maximum Undrawn Amount of their respective outstanding Letters of Credit, and each Borrower hereby irrevocably authorizes Agent, in its discretion, on such
Borrower’s behalf and in such Borrower’s name, to open such an account and to make and maintain deposits therein, or in an account opened by such Borrower, in the amounts required to be made by such Borrower, out of the proceeds of
Receivables or other Collateral or out of any other funds of such Borrower coming into any Lender’s possession at any time. Agent may, in its discretion, invest such cash collateral (less applicable reserves) in such short-term money-market
items as to which Agent and such Borrower mutually agree (or, in the absence of such agreement, as Agent may reasonably select) and the net return on such investments shall be credited to such account and constitute additional cash collateral, or
Agent may (notwithstanding the foregoing) establish the account provided for under this Section 3.2(b) as a non-interest bearing account and in such case Agent shall have no obligation (and Borrowers hereby waive any claim) under Article 9 of
the Uniform Commercial Code or PPSA or under any other Applicable Law to pay interest on such cash collateral being held by Agent. No Borrower may withdraw amounts credited to any such account except upon the occurrence of all of the following:
(x) payment and performance in full of all Obligations; (y) expiration of all Letters of Credit; and (z) termination of this Agreement. Borrowers hereby assign, pledge and grant to Agent, for its benefit and the ratable benefit of
Issuer, Lenders and each other Secured Party, a continuing security interest in and to and Lien on any such cash collateral and any right, title and interest of Borrowers in any deposit account, securities account or investment account into which
such cash collateral may be deposited from time to time to secure the Obligations or Sand Tiger’s Obligations, as applicable, specifically including all Obligations with respect to any Letters of Credit. Borrowers agree that upon the coming due
of any Reimbursement Obligations (or any other Obligations, including Obligations for Letter of Credit Fees) with respect to the Letters of Credit, Agent may, subject to Section 16.19, use such cash collateral to pay and satisfy such
Obligations. 
 3.3. Facility Fee. If, for any calendar quarter during the Term, the average daily unpaid balance of the sum of
Revolving Advances (for purposes of this computation, Swing Loans shall be deemed to be Revolving Advances made by PNC as a Lender) plus Swing Loans plus the Maximum Undrawn Amount of all outstanding Letters of Credit for each day of
such calendar quarter does not equal the Maximum Revolving Advance Amount, then Borrowers shall pay to Agent, for the ratable benefit of Lenders holding the Commitments based on their Commitment Percentages, a fee at a rate equal to three-eighths of
one percent (0.375%) per annum on the amount by which the Maximum Revolving Advance Amount exceeds such average daily unpaid balance (the “Facility Fee”). Such Facility Fee shall be payable to Agent in arrears on the first day of
each calendar quarter with respect to the previous calendar quarter. 
 3.4. Fee Letter. 

(a) Borrowers (other than Sand Tiger) shall pay the amounts required to be paid in the Fee Letter in the manner and at the times required by
the Fee Letter. 

  
 73 

[Mammoth] Credit Agreement 

 (b) All of the fees and reasonable out-of-pocket costs and expenses of any appraisals conducted
pursuant to Section 4.7 hereof shall be paid for when due, in full and without deduction, off-set or counterclaim by Borrowers. 
 3.5.
Computation of Interest and. Interest and fees hereunder shall be computed on the basis of a year of 365 days or 366 days, as applicable (360 days with respect to LIBOR Rate Loans), with respect to Base Rate Loans and for the actual number of
days elapsed. If any payment to be made hereunder becomes due and payable on a day other than a Business Day, the due date thereof shall be extended to the next succeeding Business Day and interest thereon shall be payable at the Revolving Interest
Rate for Domestic Rate Loans during such extension. For purposes of the Interest Act (Canada): (i) whenever any interest or fee under this Agreement is calculated on the basis of a period of time other than a calendar year, such rate used in
such calculation, when expressed as an annual rate, is equivalent to (x) such rate, multiplied by (y) the actual number of days in the calendar year in which the period for which such interest or fee is calculated ends, and divided by
(z) the number of days in such period of time; (ii) the principle of deemed reinvestment of interest shall not apply to any interest calculation under this Agreement; and (iii) the rates of interest stipulated in this Agreement are
intended to be nominal rates and not effective rates or yields. 
 3.6. Maximum Charges. In no event whatsoever shall interest and
other charges charged hereunder exceed the highest rate permissible under Applicable Law. In the event interest and other charges as computed hereunder would otherwise exceed the highest rate permitted under Applicable Law: (i) the interest
rates hereunder will be reduced to the maximum rate permitted under Applicable Law; (ii) such excess amount shall be first applied to any unpaid principal balance owed by Borrowers; and (iii) if the then remaining excess amount is greater
than the previously unpaid principal balance, Lenders shall promptly refund such excess amount to Borrowers and the provisions hereof shall be deemed amended to provide for such permissible rate. Notwithstanding anything to the contrary contained in
this Agreement or in any Other Document, all agreements which either now are or which shall become agreements among Credit Parties, Agent and Lenders are hereby limited so that in no contingency or event whatsoever shall the total liability for
payments in the nature of interest, additional interest and other charges exceed the applicable limits imposed by any applicable usury laws. If any payments in the nature of interest, additional interest and other charges made under this Agreement
or any Other Document are held to be in excess of the limits imposed by any applicable usury laws, it is agreed that any such amount held to be in excess shall be considered payment of principal hereunder, and the indebtedness evidenced hereby shall
be reduced by such amount so that the total liability for payments in the nature of interest, additional interest and other charges shall not exceed the applicable limits imposed by any applicable usury laws, in compliance with the desires of Credit
Parties and Agent. The foregoing provisions shall never be superseded or waived and shall control every other provision of this Agreement or any Other Document and all agreements among Borrowers and Agent and Lenders, or their respective successors
and assigns. If the applicable state or federal law is amended in the future to allow a greater rate of interest to be charged under this Agreement than is presently allowed by applicable state or federal law, then the limitation of interest
hereunder shall be increased to the maximum rate of interest allowed by applicable state or federal law as amended, which increase shall be effective hereunder on the effective date of such amendment, and all interest charges owing to Lender by
reason thereof shall be payable in 

  
 74 

[Mammoth] Credit Agreement 

 
accordance with Section 3.1 of this Agreement. If by operation of this provision, Borrowers would be entitled to a refund of interest paid pursuant to this Agreement, each Lender
agrees that it shall pay to Borrowers upon Agent’s request such Lender’s Commitment Percentage, of such interest to be refunded, as determined by Agent. If any provision of this Agreement or Other Documents would oblige any Borrower to
make any payment of interest or other amount payable to any Lender in an amount or calculated at a rate which would be prohibited by law or would result in a receipt by that Lender of “interest” at a “criminal rate” (as such
terms are construed under the Criminal Code (Canada)), then, notwithstanding such provision, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would
not be so prohibited by Applicable Law or so result in a receipt by that Lender of “interest” at a “criminal rate”, such adjustment to be effected, to the extent necessary (but only to the extent necessary), as follows: first, by
reducing the amount or rate of interest, and, thereafter, by reducing any fees, commissions, costs, expenses, premiums and other amounts required to be paid to the affected Lender which would constitute interest for purposes of section 347 of the
Criminal Code (Canada). 
 3.7. Increased Costs. In the event that any Applicable Law or any Change in Law or compliance by any
Lender (for purposes of this Section 3.7, the term “Lender” shall include Agent, Swing Loan Lender, any Issuer or Lender and any corporation or bank controlling Agent, Swing Loan Lender, any Lender or Issuer and the office or branch
where Agent, Swing Loan Lender, any Lender or Issuer (as so defined) makes or maintains any LIBOR Rate Loans) with any request or directive (whether or not having the force of law) from any central bank or other financial, monetary or other
authority, shall: 
 (a) subject Agent, Swing Loan Lender, any Lender or Issuer to any tax of any kind whatsoever with respect to this
Agreement, any Letter of Credit, any participation in a Letter of Credit or any LIBOR Rate Loan, or change the basis of taxation of payments to Agent, Swing Loan Lender, such Lender or Issuer in respect thereof (except for Indemnified Taxes or Other
Taxes covered by Section 3.10 and the imposition of, or any change in the rate of, any Excluded Tax payable by Agent, Swing Loan Lender, such Lender or the Issuer); 

(b) impose, modify or deem applicable any reserve, special deposit, assessment, special deposit, compulsory loan, insurance charge or similar
requirement against assets held by, or deposits in or for the account of, advances or loans by, or other credit extended by, any office of Agent, Swing Loan Lender, Issuer or any Lender, including pursuant to Regulation D of the Board of Governors
of the Federal Reserve System; or 
 (c) impose on Agent, Swing Loan Lender, any Lender or Issuer or the London interbank LIBOR market any
other condition, loss or expense (other than Taxes) affecting this Agreement or any Other Document or any Advance made by any Lender, or any Letter of Credit or participation therein; 

and the result of any of the foregoing is to increase the cost to Agent, Swing Loan Lender, any Lender or Issuer of making, converting to,
continuing, renewing or maintaining its Advances hereunder or to reduce the amount of any payment (whether of principal, interest or otherwise) in respect of any of the Advances, then, in any case Borrowers shall promptly pay Agent, Swing Loan
Lender, such Lender or Issuer, upon its demand, such additional amount as will compensate 

  
 75 

[Mammoth] Credit Agreement 

 
Agent, Swing Loan Lender or such Lender or Issuer for such additional cost or such reduction, as the case may be, provided that the foregoing shall not apply to increased costs which are
reflected in the LIBOR Rate, as the case may be (provided, that Sand Tiger shall only be liable for any such costs or expenses attributable to Sand Tiger’s Obligations). Agent, Swing Loan Lender, such Lender or Issuer shall certify the amount
of such additional cost or reduced amount to Borrowing Agent within three hundred sixty (360) days of the occurrence thereof, and such certification shall be conclusive absent manifest error. 

3.8. Basis For Determining Interest Rate Inadequate or Unfair. In the event that Agent or any Lender shall have determined that: 

(a) reasonable means do not exist for ascertaining the LIBOR Rate applicable pursuant to Section 2.2 hereof for any Interest Period; or

 (b) Dollar deposits in the relevant amount and for the relevant maturity are not available in the London interbank LIBOR market, with
respect to an outstanding LIBOR Rate Loan, a proposed LIBOR Rate Loan, or a proposed conversion of a Domestic Rate Loan into a LIBOR Rate Loan; or 

(c) the making, maintenance or funding of any LIBOR Rate Loan has been made impracticable or unlawful by compliance by Agent or such Lender in
good faith with any Applicable Law or any interpretation or application thereof by any Governmental Body or with any request or directive of any such Governmental Body (whether or not having the force of law), 

then Agent shall give Borrowing Agent prompt written or telephonic notice of such determination. If such notice is given, (i) any such
requested LIBOR Rate Loan shall be made as a Domestic Rate Loan, unless Borrowing Agent shall notify Agent no later than 1:00 p.m. two (2) Business Days prior to the date of such proposed borrowing, that its request for such borrowing shall be
cancelled or made as an unaffected type of LIBOR Rate Loan, (ii) any Domestic Rate Loan or LIBOR Rate Loan which was to have been converted to an affected type of LIBOR Rate Loan shall be continued as or converted into a Domestic Rate Loan, or,
if Borrowing Agent shall notify Agent, no later than 1:00 p.m. two (2) Business Days prior to the proposed conversion, shall be maintained as an unaffected type of LIBOR Rate Loan, and (iii) any outstanding affected LIBOR Rate Loans shall
be converted into a Domestic Rate Loan, or, if Borrowing Agent shall notify Agent, no later than 1:00 p.m. two (2) Business Days prior to the last Business Day of the then current Interest Period applicable to such affected LIBOR Rate Loan,
shall be converted into an unaffected type of LIBOR Rate Loan, on the last Business Day of the then current Interest Period for such affected LIBOR Rate Loans (or sooner, if any Lender cannot continue to lawfully maintain such affected LIBOR Rate
Loan). Until such notice has been withdrawn, Lenders shall have no obligation to make an affected type of LIBOR Rate Loan or maintain outstanding affected LIBOR Rate Loans and no Borrower shall have the right to convert a Domestic Rate Loan or an
unaffected type of LIBOR Rate Loan into an affected type of LIBOR Rate Loan. 
 3.9. Capital Adequacy. 

(a) In the event that Agent, Swing Loan Lender or any Lender shall have determined that any Applicable Law or guideline regarding capital
adequacy or liquidity 

  
 76 

[Mammoth] Credit Agreement 

 
requirements, or any Change in Law or any change in the interpretation or administration thereof by any Governmental Body, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by Agent, Swing Loan Lender, Issuer or any Lender (for purposes of this Section 3.9, the term “Lender” shall include Agent, Swing Loan Lender, Issuer or any Lender and any corporation or bank
controlling Agent, Swing Loan Lender or any Lender and the office or branch where Agent, Swing Loan Lender or any Lender (as so defined) makes or maintains any LIBOR Rate Loans) with any request or directive regarding capital adequacy or liquidity
requirements (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on Agent within three hundred sixty (360) days after such request or
directive, Swing Loan Lender or any Lender’s capital as a consequence of its obligations hereunder (including the making of any Swing Loans) to a level below that which Agent, Swing Loan Lender or such Lender could have achieved but for such
adoption, change or compliance (taking into consideration Agent’s, Swing Loan Lender’s and each Lender’s policies with respect to capital adequacy), then, from time to time, Borrowers shall pay upon demand to Agent, Swing Loan Lender
or such Lender such additional amount or amounts as will compensate Agent, Swing Loan Lender or such Lender for such reduction (provided, that Sand Tiger shall only be liable for any such amounts attributable to Sand Tiger’s Obligations). In
determining such amount or amounts, Agent, Swing Loan Lender or such Lender may use any reasonable averaging or attribution methods. The protection of this Section 3.9 shall be available to Agent, Swing Loan Lender and each Lender regardless of
any possible contention of invalidity or inapplicability with respect to the Applicable Law, rule, regulation, guideline or condition. 

(b) A certificate of Agent, Swing Loan Lender or such Lender setting forth such amount or amounts as shall be necessary to compensate Agent,
Swing Loan Lender or such Lender with respect to Section 3.9(a) hereof when delivered to Borrowing Agent shall be conclusive absent manifest error. 

3.10. Taxes. 
 (a) Any and
all payments by or on account of any Obligations hereunder or under any Other Document shall be made free and clear of and without reduction or withholding for any Taxes except to the extent required by Applicable Law; provided that if the
Borrowers shall be required by Applicable Law to deduct any Taxes from such payments, then (i) if such Taxes are Indemnified Taxes, the sum payable shall be increased as necessary so that after making all required deductions for Indemnified
Taxes (including deductions for Indemnified Taxes applicable to additional sums payable under this Section 3.10) the Recipient receives an amount equal to the sum it would have received had no such deductions for Indemnified Taxes been made,
(ii) the Borrowers or other applicable withholding agent shall make such deductions and (iii) the Borrowers or other applicable withholding agent shall timely pay the full amount deducted to the relevant Governmental Body in accordance
with Applicable Law.

interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Body. A certificate as to the amount of such
payment or liability delivered to the Borrowers by any Recipient (with a copy to Agent) shall be conclusive absent manifest error (provided, Sand Tiger shall only be liable for any such Taxes attributable to Sand Tiger’s Obligations). 

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by any Borrower to a Governmental Body, the Borrowers shall

judgment it is required to do so under the due diligence requirements imposed upon a withholding agent under § 1.1441-7(b) of the United States Income Tax Regulations or other Applicable Law. Further, Agent is indemnified under §
1.1461-1(e) of the United States Income Tax Regulations against any claims and demands of any Recipient for the amount of any Tax it deducts and withholds in accordance with regulations under § 1441 of the Code. In addition, any Recipient, if

valid (2) originals of an IRS Form W-9 or any other form prescribed by Applicable Law certifying that such Recipient is exempt from United States federal backup withholding tax. 

(f) If a payment made to a Recipient under this Agreement or any Other Document would be subject to U.S. Federal withholding Tax imposed by
FATCA if such Person fails to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Recipient shall deliver to the Agent (in the case of Swing Loan
Lender, a Lender, Participant or Issuer) and the Borrowers (i) a certification signed by the chief financial officer, principal accounting officer, treasurer or controller of such Person, and (i) such documentation prescribed by applicable
law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such other documentation reasonably requested by the Agent or any Borrower sufficient for Agent and the Borrowers to comply with their obligations under FATCA and to

 (d) If Agent, Swing Loan Lender, a Lender, a Participant or Issuer determines, in its
sole discretion, that it has received a refund of any Indemnified Taxes or Other Taxes as to which it has been indemnified by Borrowers or with respect to which Borrowers have paid additional amounts pursuant to this Section, it shall pay to
Borrowers an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by Borrowers under this Section with respect to the Indemnified Taxes or Other Taxes giving rise to such refund); net of all
out-of-pocket expenses of the Agent, Swing Loan Lender, such Lender, Participant, or the Issuer, as the case may be, and without interest (other than any interest paid by the relevant Governmental Body with respect to such refund), provided that
Borrowers, upon the request of Agent, Swing Loan Lender, such Lender, Participant, or Issuer, agrees to repay the amount paid over to Borrowers (plus any penalties, interest or other charges imposed by the relevant Governmental Body) to Agent, Swing
Loan Lender, such Lender, Participant or the Issuer in the event Agent, Swing Loan Lender, such Lender, Participant or the Issuer is required to repay such refund to such Governmental Body. This Section shall not be construed to require Agent, Swing
Loan Lender, any Lender, Participant, or Issuer to make available its tax returns (or any other information relating to its taxes that it deems confidential) to Borrowers or any other Person. 

3.11. Replacement of Lenders. If any Lender (an “Affected Lender”) (a) makes demand upon Borrowers for (or if
Borrowers are otherwise required to pay) amounts pursuant to Section 3.7, 3.9 or 3.10 hereof, (b) is unable to make or maintain LIBOR Rate Loans as a result of a condition described in Section 2.2(h) hereof, (c) is a Defaulting
Lender, or (d) denies any consent requested by the Agent pursuant to Section 16.2(b) hereof, Borrowers may, within forty-five (45) days of receipt of such demand, notice (or the occurrence of such other event causing Borrowers to be
required to pay such compensation or causing Section 2.2(h) hereof to be applicable), or such Lender becoming a Defaulting Lender or denial of a request by the Agent pursuant to Section 16.2(b) hereof, as the case may be, by notice (a
“Replacement Notice”) in writing to the Agent and such Affected Lender (i) request the Affected Lender to cooperate with Borrowers in obtaining a replacement Lender satisfactory to the Agent and Borrowers (the
“Replacement Lender”); (ii) request the non-Affected Lenders to acquire and assume all of the Affected Lender’s Advances and its Commitment Percentage, as provided herein, but none of such Lenders shall be under any
obligation to do so; or (iii) propose a Replacement Lender subject to approval by the Agent in its good faith business judgment; provided, (x) in the case of any such replacement resulting from a claim for compensation under
Section 3.7, 3.9 or 3.10 hereof, such replacement will result in a reduction of such compensation from the Replacement Lender at the time of such replacement; and (y) such replacement does not conflict with applicable
law. If any satisfactory Replacement Lender shall be obtained, and/or if any one or more of the non-Affected Lenders shall agree to acquire and assume all of the Affected Lender’s Advances and its Commitment Percentage, then such Affected
Lender shall assign, in accordance with Section 16.3 hereof, all of its Advances and its Commitment Percentage, and other rights and obligations under this Loan Agreement and the Other Documents to such Replacement Lender or non-Affected
Lenders, as the case may be, in exchange for payment of the principal amount so assigned and all interest and fees accrued on the amount so assigned, plus all other Obligations then due and payable to the Affected Lender. If any

  
 80 

[Mammoth] Credit Agreement 

 
Affected Lender does not execute an assignment in accordance with Section 16.3 within five (5) Business Days after receipt of notice to do so by Agent or Borrowing Agent, then Agent
shall be entitled (but not obligated) to execute such assignment on behalf of such Affected Lender, which shall be effective for purposes of Section 16.3 and this Agreement.

this Agreement and the Other Documents, Agent’s security interests in the Collateral shall continue in full force and effect except to the extent released pursuant to the terms of this Agreement. Each Borrower shall use all commercially
reasonable efforts to defend Agent’s interests in the Collateral against any and all Persons whatsoever. At any time following demand by Agent for payment of all Obligations after the occurrence of and during the continuance of an Event of
Default, Agent shall have the right to take possession of the indicia of the Collateral and the Collateral in whatever physical form contained, including: labels, stationery, documents, instruments and advertising materials. If Agent exercises this
right to take possession of the Collateral, after the occurrence of and during the continuance of an Event of Default, Borrowers shall, upon demand, assemble it in the best manner possible and make it available to Agent at a place reasonably
convenient to Agent. In addition, with respect to all Collateral, Agent and Lenders shall be entitled to all of the rights and remedies set forth herein and further provided by the Uniform Commercial Code, PPSA or other Applicable Law. Each Borrower
shall, and Agent may, at its option after the occurrence and during the continuance of an Event of Default, instruct all suppliers, carriers, forwarders, warehousers or others receiving or holding cash, checks, Inventory, documents or instruments in
which Agent holds a security interest to deliver same to Agent and/or subject to Agent’s order and if they shall come into any Borrower’s possession, they, and each of them, shall be held by such Borrower in trust as Agent’s trustee,

identified by Borrowers to be included in the calculation of the Formula Amount. Absent the occurrence and continuance of an Event of Default at such time, Agent shall consult with Borrowers as to the identity of any such firm. In the event the
value of Borrowers’ Inventory or Eligible Equipment, as so determined pursuant to such appraisal, is less than anticipated by Agent or Lenders, such that the Revolving Advances are in excess of such Advances permitted hereunder, then, promptly
upon Agent’s demand for same, Borrowers shall make mandatory prepayments of the then outstanding Revolving Advances so as to eliminate the excess Advances.

(a) Nature of Receivables. Each of the Receivables at any time reported to Agent (whether pursuant to Section 9.2 or
otherwise) shall, except as noted therein, be a bona fide and valid account representing a bona fide indebtedness incurred by the Customer therein named, for a fixed sum (subject to customary discounts or reductions permitted in the ordinary course

Indebtedness. 
 (e) At any time following the occurrence, and during the continuance of, an Event of Default or a Default, Agent shall have
the right to send notice of the assignment of, and Agent’s security interest in and Lien on, the Receivables to any and all Customers or any third party holding or otherwise concerned with any of the Collateral. At any time after the occurrence
and during the continuance of an Event of Default, Agent shall have the sole right to collect the Receivables, take possession of the Collateral, or both. Agent’s actual collection expenses, including, but not limited to, stationery and

Receivables, upon and during the continuance of an Event of Default; (iii) to send verifications of Receivables to any Customer (provided, that, so long as no Event of Default has occurred and is continuing, Agent shall only conduct
verifications of Receivables over the phone with participation from Borrowers or with Borrowers being present); (iv) to sign such Borrower’s name on any documents or instruments deemed necessary or appropriate by Agent to preserve,
protect, or perfect Agent’s interest in the Collateral and to file same upon and during the continuance of an Event of Default; (v) to demand payment of the Receivables upon and during the continuance of an Event of Default; (vi) to
enforce payment of the Receivables by legal proceedings or otherwise upon and during the continuance of an Event of Default; (vii) to exercise all of such Borrower’s rights and remedies with respect to the collection of the Receivables and

omission or commission nor for any error of judgment or mistake of fact or of law, unless constituting willful misconduct or gross negligence (as determined by a court of competent jurisdiction in a final non-appealable judgment); this power being
coupled with an interest is irrevocable while any of the Obligations remain unpaid. Agent shall have the right at any time following the occurrence and during the continuation of an Event of Default, to change the address for delivery of mail
addressed to any Borrower to such address as Agent may designate and to receive, open and dispose of all mail addressed to any Borrower. 

(g) No Liability. Neither Agent nor any Lender shall, under any circumstances or in any event whatsoever, have any liability for any
error or omission or delay of any kind occurring in the settlement, collection or payment of any of the Receivables or any instrument received in payment thereof, or for any damage resulting therefrom, except for the gross negligence or willful
misconduct of the Agent as determined by a final and non-appealable judgment of a court of competent jurisdiction. Following the occurrence and during the continuance of an Event of Default, Agent may, without notice or consent from any Borrower,

Adverse Effect (except to the extent any separate provision of this Agreement shall expressly require compliance with any particular Applicable Law(s) pursuant to another standard). Each Borrower may, however, contest or dispute any Applicable Laws
in any reasonable manner, provided that any related Lien is inchoate or stayed and sufficient reserves are established to the reasonable satisfaction of Agent to protect Agent’s Lien on or security interest in the Collateral. 

6.2. Conduct of Business and Maintenance of Existence and Assets. (a) Conduct continuously and operate actively its business
according to good business practices and maintain all of its properties useful or necessary in its business in good working order and condition (reasonable wear and tear excepted and except as may be disposed of in accordance with the terms of this
Agreement), including all Intellectual Property necessary for the Borrowers’ business and take all actions necessary to enforce and protect the validity of any intellectual property right or other right included in the Collateral; (b) keep
in full force and effect its existence and comply in all material respects with the laws and regulations governing the conduct of its business where the failure to do so could reasonably be expected to have a Material Adverse Effect; and
(c) make all such reports and pay all such franchise and other taxes and license fees and do all such other acts and things as may be lawfully required to maintain its rights, licenses, leases, powers and franchises under the laws of the United
States or any political subdivision thereof where the failure to do so could reasonably be expected to have a Material Adverse Effect. 

6.3. Books and Records. Keep proper books of record and account in which full, true and correct entries will be made of all dealings or
transactions of or in relation to its business and affairs (including without limitation accruals for taxes, assessments, Charges, levies and claims, allowances against doubtful Receivables and accruals for depreciation, obsolescence or amortization
of assets), all in accordance with, or as required by, GAAP consistently applied in the opinion of such independent public accountant as shall then be regularly engaged by Borrowers. 

6.4. Payment of Taxes; Priority Payables. Pay, when due, all Priority Payables and all taxes, assessments and other Charges
lawfully levied or assessed upon such Borrower or any of the Collateral, including real and personal property taxes, municipal and business taxes, assessments and charges and all franchise, income, employment, social security benefits, withholding,
and sales taxes except to the extent any such tax is being contested in good faith. If any tax by any Governmental Body is or may be imposed on or as a result of any transaction between any Borrower and Agent or any Lender which Agent or any Lender
may be required to withhold or pay or if any taxes, assessments, or other Charges remain unpaid after the date fixed for their payment, or if any claim shall be made which, in Agent’s or any Lender’s opinion, may possibly create a valid
Lien on the Collateral, Agent may without notice to Borrowers pay the taxes, assessments or other Charges and each Borrower hereby indemnifies and holds Agent and each Lender harmless in respect thereof. Agent will not pay any taxes, assessments or
Charges to the extent that any 

  
 97 

[Mammoth] Credit Agreement 

 
applicable Borrower has Properly Contested those taxes, assessments or Charges. The amount of any payment by Agent under this Section 6.4 shall be charged to Borrowers’ Account as a
Revolving Advance maintained as a Domestic Rate Loan and added to the Obligations and, until Borrowers shall furnish Agent with an indemnity therefor (or supply Agent with evidence satisfactory to Agent that due provision for the payment thereof has
been made), Agent may hold without interest any balance standing to Borrowers’ credit and Agent shall retain its security interest in and Lien on any and all Collateral held by Agent. 

6.5. Financial Covenants. 

(a) Interest Coverage Ratio. Cause to be maintained as of the last day of each fiscal quarter beginning with the fiscal quarter ending
December 31, 2014, for the four fiscal quarter period then ending, an Interest Coverage Ratio of not less than 3.00 to 1.00, measured as of the last day of the most recently ended fiscal quarter for the twelve month period then ended. 

(b) Leverage Ratio. Maintain as of the last day of each fiscal quarter, for the four fiscal quarter period then ending beginning with
the fiscal quarter ending December 31, 2014, a ratio of Funded Debt to EBITDA (the “Leverage Ratio”) of not greater than 4.0 to 1.00; provided, however, that Borrowers shall maintain a ratio of Funded Debt to
EBITDA of not greater than 4.25 to 1.00 as of the end of each of the two fiscal quarters following any Permitted Acquisition, in each case, for the four fiscal quarters then
ending.(c) Minimum Excess Availability. At all times prior to the Qualified IPO, Borrowers shall maintain Excess Availability of not less than the greater of
(i) $10,000,000 or (ii) 6.7% of the Maximum Revolving Advance Amount. 

6.6. Insurance. 
 (a) (i)
Keep all its insurable properties and properties in which such Borrower has an interest insured against the hazards of fire, flood, sprinkler leakage, those hazards covered by extended coverage insurance and such other hazards, and for such amounts,
as is customary in the case of the Borrower’s properties or companies engaged in businesses similar to such Borrower’s including business interruption insurance; (ii) maintain a bond in such amounts as is customary in the case of
companies engaged in businesses similar to such Borrower insuring against larceny, embezzlement or other criminal misappropriation of insured’s officers and employees who may either singly or jointly with others at any time have access to the
assets or funds of such Borrower either directly or through authority to draw upon such funds or to direct generally the disposition of such assets; (iii) maintain public and product liability insurance against claims for personal injury, death
or property damage suffered by others as is customary in the case of the Borrower’s properties or companies engaged in businesses similar to such Borrower’s; (iv) maintain all such worker’s compensation or similar insurance as
may be required under the laws of any state or jurisdiction in which such Borrower is engaged in business; (v) furnish Agent with (A) copies of all policies and evidence of the maintenance of such policies by the renewal thereof at least
thirty (30) days before any expiration date, and (B) appropriate loss payable endorsements in form and substance satisfactory to Agent, naming Agent as an additional insured and mortgagee and/or lender loss payee (as applicable) as its
interests may appear with respect to all insurance coverage referred to in clauses (i), and (iii) above, and providing (I) that, during any Trigger Period, all proceeds thereunder shall be payable to Agent, (II) no such insurance shall be
affected 

  
 98 

[Mammoth] Credit Agreement 

 
by any act or neglect of the insured or owner of the property described in such policy, and (III) that such policy and loss payable clauses may not be cancelled, amended or terminated unless at
least thirty (30) days prior written notice is given to Agent (or in the case of non-payment, at least ten (10) days prior written notice). In the event of any loss thereunder, during any Trigger Period, the carriers named therein hereby
are directed by Agent and the applicable Borrower to make payment for such loss to Agent and not to such Borrower and Agent jointly. If any insurance losses are paid by check, draft or other instrument payable to any Borrower and Agent jointly,
Agent may endorse such Borrower’s name thereon and do such other things as Agent may deem advisable to reduce the same to cash. 
 (b)
Each Borrower shall take all actions required under the Flood Laws and/or requested by Agent to assist in ensuring that each Lender is in compliance with the Flood Laws applicable to the Collateral, including, but not limited to, providing Agent
with the address and/or GPS coordinates of each structure on any real property that will be subject to a mortgage in favor of Agent, for the benefit of Lenders, and, to the extent required, obtaining flood insurance for such property, structures and
contents prior to such property, structures and contents becoming Collateral, and thereafter maintaining such flood insurance in full force and effect for so long as required by the Flood Laws. 

(c) Agent is hereby authorized to adjust and compromise claims under insurance coverage referred to in Sections 6.6(a)(i) and (iii) and
6.6(b) above. During any Trigger Period, all loss recoveries shall be payable to Agent and all loss recoveries received by Agent under any such insurance may be applied to the Obligations, in such order as Agent in its sole discretion shall
determine. Any surplus shall be paid by Agent to Borrowers or applied as may be otherwise required by law. During any Trigger Period, any deficiency thereon shall be paid by Borrowers to Agent, on demand. Anything hereinabove to the contrary
notwithstanding, and subject to the fulfillment of the conditions set forth below, Agent shall remit to Borrowing Agent insurance proceeds received by Agent during any calendar year under insurance policies procured and maintained by Borrowers which
insure Borrowers’ insurable properties to the extent such insurance proceeds do not exceed $10,000,000 in the aggregate during such calendar year or $1,000,000 per occurrence. In the event the amount of insurance proceeds received by Agent for
any occurrence exceeds $1,000,000, then Agent shall not be obligated to remit the insurance proceeds to Borrowing Agent unless Borrowing Agent shall provide Agent with evidence reasonably satisfactory to Agent that the insurance proceeds will be
used by Borrowers to repair, replace or restore the insured property which was the subject of the insurable loss. In the event Borrowing Agent has previously received (or, after giving effect to any proposed remittance by Agent to Borrowing Agent
would receive) insurance proceeds which equal or exceed $10,000,000 in the aggregate during any calendar year, then Agent may, in its sole discretion, either remit the insurance proceeds to Borrowing Agent upon Borrowing Agent providing Agent with
evidence reasonably satisfactory to Agent that the insurance proceeds will be used by Borrowers to repair, replace or restore the insured property which was the subject of the insurable loss, or apply the proceeds to the Obligations, as aforesaid.
The agreement of Agent to remit insurance proceeds in the manner above provided shall be subject in each instance to satisfaction of each of the following conditions: (x) No Event of Default or Default shall then have occurred and be
continuing, (y) Borrowers shall use such insurance proceeds promptly to repair, replace or restore the insurable property which was the subject of the insurable loss and for no other purpose, and (z) such

  
 99 

[Mammoth] Credit Agreement 

 
remittances shall be made under such procedures as Agent may establish. If any Borrower fails to obtain insurance as hereinabove provided, or to keep the same in force, Agent, if Agent so elects,
may obtain such insurance and pay the premium therefor on behalf of such Borrower, which payments shall be charged to Borrowers’ Account or Sand Tiger’s Account, as applicable, and constitute part of the obligations. 

6.7. Payment of Indebtedness and Leasehold Obligations. Pay, discharge or otherwise satisfy (i) at or before maturity (subject,
where applicable, to specified grace periods) all its Indebtedness, except when the failure to do so could not reasonably be expected to have a Material Adverse Effect or when the amount or validity thereof is currently being Properly Contested,
subject at all times to any applicable subordination arrangement in favor of Lenders and (ii) when due its rental obligations under all leases under which it is a tenant, and shall otherwise comply, in all material respects, with all other
terms of such leases and keep them in full force and effect. 
 6.8. Environmental Matters. 

(a) Use commercially reasonable efforts to ensure that the Real Property and all operations and businesses conducted thereon are in material
compliance and remain in material compliance with all Environmental Laws and it shall manage any and all Hazardous Substances on any Real Property in material compliance with Environmental Laws. 

(b) Establish and maintain an environmental management and compliance system to assure and monitor continued compliance with all applicable
Environmental Laws which system shall include periodic environmental compliance audits to be conducted by knowledgeable environmental professionals. All potential violations and violations of Environmental Laws shall be reviewed with legal counsel
to determine any required reporting to applicable Governmental Bodies and any required corrective actions to address such potential violations or violations. 

(c) Respond promptly to any Hazardous Discharge or Environmental Complaint known to a Borrower and take all necessary action in order to
safeguard the health of any Person and to avoid subjecting a material portion of the Collateral or Real Property to any Lien. If any Borrower shall fail to respond promptly to any Hazardous Discharge or Environmental Complaint or any Borrower shall
fail to comply with any of the requirements of any Environmental Laws, and such failure results in an Event of Default, Agent on behalf of Lenders may, but without the obligation to do so, for the sole purpose of protecting Agent’s interest in
the Collateral: (i) give such notices or (ii) enter onto the Real Property (or authorize third parties to enter onto the Real Property) and take such actions as Agent (or such third parties as directed by Agent) deem reasonably necessary,
to remediate, remove, mitigate or otherwise manage with any such Hazardous Discharge or Environmental Complaint. All reasonable out-of-pocket costs and expenses incurred by Agent and Lenders (or such third parties) in the exercise of any such
rights, including any sums paid in connection with any judicial or administrative investigation or proceedings, fines and penalties, together with interest thereon from the date expended at the Default Rate for Domestic Rate Loans constituting
Revolving Advances shall be paid upon demand by Borrowers (other than Sand Tiger) or Sand Tiger, as applicable, and until paid shall be added to and become a part of the Obligations secured by the Liens created by the terms of this Agreement or any
other agreement between Agent, any Lender and any Borrower.

[Mammoth] Credit Agreement 

 (d) Promptly upon the written reasonable request of Agent from time to time, Borrowers shall
provide Agent, at Borrowers’ expense once every three (3) years (or at any time following the occurrence of and during the continuance of an Event of Default or if there exists any known Hazardous Discharge or Environmental Complaint),
with an environmental site assessment or environmental compliance audit report prepared by an environmental engineering firm acceptable in the reasonable opinion of Agent, to assess with a reasonable degree of certainty the existence of a Hazardous
Discharge and the potential costs in connection with abatement, remediation and removal of any Hazardous Substances found on, under, at or within the Real Property. Any report or investigation of such Hazardous Discharge proposed and acceptable to
the responsible Governmental Body shall be acceptable to Agent. If such estimates, individually or in the aggregate, exceed $500,000, Agent shall have the right to require Borrowers to post a bond, letter of credit or other security reasonably
satisfactory to Agent to secure payment of these costs and expenses.

Non-Qualifying Party (it being understood and agreed that this guarantee is a guaranty of payment and not of collection), and (b) undertakes to provide such funds or other support as may be
needed from time to time by any Non-Qualifying Party to honor all of such Non-Qualifying Party’s obligations under this Agreement or any Other Document in respect of Swap Obligations (provided, however,

6.16. Negative Pledge Agreements. Borrowers shall deliver a Negative Pledge Agreement with respect to each parcel of Real Property
which is not included in the Collateral as of the Closing Date and, upon the occurrence of a Default or an Event of Default, at Agent’s request, Borrowers shall execute such security agreements as are necessary under law or otherwise requested

	XI.	LENDERS’ RIGHTS AND REMEDIES AFTER DEFAULT. 

 11.1. Rights and Remedies. 

(a) Upon the occurrence and continuance of: (i) an Event of Default pursuant to Section 10.7 all Obligations shall be immediately due
and payable and this Agreement and the obligation of Lenders to make Advances shall be deemed terminated; and, (ii) any of the other Events of Default and at any time thereafter, at the option of Required Lenders all Obligations shall be
immediately due and payable and Lenders shall have the right to terminate this Agreement and to terminate the obligation of Lenders to make Advances; and (iii) a filing of a petition against any Borrower in any involuntary case under any state
or federal bankruptcy laws, all Obligations shall be immediately due and payable and the obligation of Lenders to make Advances hereunder shall be terminated other than as may be required by an appropriate order of the bankruptcy court having
jurisdiction over such Borrower. Upon the occurrence and during the continuation of any Event of Default, subject to Applicable Law, Agent shall have the right to exercise any and all rights and remedies provided for herein, under the Other
Documents, under the Uniform Commercial Code, PPSA and at law or equity generally, including the right to foreclose the security interests granted herein and to realize upon any Collateral by any available judicial procedure and/or to take
possession of and sell any or all of the Collateral with or without judicial process. Agent may enter any of any Borrower’s premises or other premises without legal process and without incurring liability to any Borrower therefor, and Agent may
thereupon, or at any time thereafter, in its discretion without notice or demand, take the Collateral and remove the same to such place as Agent may deem advisable and Agent may require Borrowers to make the Collateral available to Agent at a
convenient place. With or without having the Collateral at the time or place of sale, Agent may sell the Collateral, or any part thereof, at public or private sale, at any time or place, in one or more sales, at such price or prices, and upon such
terms, either for cash, credit or future delivery, as Agent may elect. Except as to that part of the Collateral which is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, Agent shall give
Borrowers reasonable notification of such sale or sales, it being agreed that in all events written notice mailed to Borrowing Agent at least ten (10) days prior to such sale or sales is reasonable notification. At any public sale Agent or any
Lender may bid for and become the purchaser, and Agent, any Lender or any other purchaser at any such sale thereafter shall hold the Collateral sold absolutely free from any claim or right of whatsoever kind, including any equity of redemption and
all such claims, rights and equities are hereby expressly waived and released by each Borrower. In connection with the exercise of the foregoing remedies, including the sale of Inventory, Agent is granted a perpetual nonrevocable, royalty free,
nonexclusive license and Agent is granted permission to use all of each Borrower’s (a) trademarks, trade styles, trade names, trade name applications, domain names, domain name applications, patents, patent applications, copyrights,
service marks, licenses, franchises and other proprietary rights which are used or useful in connection with Inventory for the purpose of marketing, advertising for sale and selling or otherwise disposing of such Inventory and (b) Equipment for
the purpose of completing the manufacture of unfinished goods. The cash proceeds realized from the sale of any Collateral shall be applied to the Obligations in the order set forth in Section 11.5 hereof unless required otherwise by Applicable
Law. Noncash proceeds will only be applied to the Obligations as they are converted into cash. If any deficiency shall arise, Borrowers shall remain liable to Agent and Lenders therefor. 

  
 120 

[Mammoth] Credit Agreement 

 (b) To the extent that Applicable Law imposes duties on Agent to exercise remedies in a
commercially reasonable manner, each Borrower acknowledges and agrees that it is not commercially unreasonable for Agent: (i) to fail to incur expenses reasonably deemed significant by Agent to prepare Collateral for disposition or otherwise to
complete raw material or work in process into finished goods or other finished products for disposition; (ii) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to
fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of; (iii) to fail to exercise collection remedies against Customers or other Persons obligated on Collateral or to
remove Liens on or any adverse claims against Collateral; (iv) to exercise collection remedies against Customers and other Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists;
(v) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature; (vi) to contact other Persons, whether or not in the same business as any Borrower,
for expressions of interest in acquiring all or any portion of such Collateral; (vii) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature;
(viii) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets;
(ix) to dispose of assets in wholesale rather than retail markets; (x) to disclaim disposition warranties, such as title, possession or quiet enjoyment, (xi) to purchase insurance or credit enhancements to insure Agent against risks
of loss, collection or disposition of Collateral or to provide to Agent a guaranteed return from the collection or disposition of Collateral; or (xii) to the extent deemed appropriate by the Agent, to obtain the services of other brokers,
investment bankers, consultants and other professionals to assist Agent in the collection or disposition of any of the Collateral. Each Borrower acknowledges that the purpose of this Section 11.1(b) is to provide non-exhaustive indications of
what actions or omissions by Agent would not be commercially unreasonable in Agent’s exercise of remedies against the Collateral and that other actions or omissions by Agent shall not be deemed commercially unreasonable solely on account of not
being indicated in this Section 11.1(b). Without limitation upon the foregoing, nothing contained in this Section 11.1(b) shall be construed to grant any rights to any Borrower or to impose any duties on Agent that would not have been
granted or imposed by this Agreement or by Applicable Law in the absence of this Section 11.1(b). 
 (c) Upon the occurrence of an
Event of Default which is continuing, Agent may seek the appointment of a receiver, receiver-manager, monitor or keeper (a “Receiver”) under the laws of Canada or any Province thereof including to take possession of all or any
portion of the Collateral of Credit Parties or to operate same and, to the maximum extent permitted by law, may seek the appointment of such a receiver without the requirement of prior notice or a hearing. Any such Receiver shall, so far as concerns
responsibility for his/her acts, be deemed agent of Credit Parties and not Agent and the Lenders, and Agent and the Lenders shall not be in any way responsible for any misconduct, negligence or non-feasance on the part of any such Receiver, his/her
servants or employees. Subject to the provisions of the instrument appointing him/her, any such Receiver shall have power to take possession of Collateral of the Credit Parties, to preserve Collateral of the Credit Parties or its value, to carry on
or concur in carrying on all or any part of the business of the Credit Parties and to sell, lease, license or otherwise dispose of or concur in selling, leasing, licensing or otherwise disposing of Collateral of the Credit Parties. To facilitate

  
 121 

[Mammoth] Credit Agreement 

 
the foregoing powers, any such Receiver may, to the exclusion of all others, including the Credit Parties, enter upon, use and occupy all premises owned or occupied by the Credit Parties wherein
Collateral of the Credit Parties may be situated, maintain Collateral of the Credit Parties upon such premises, borrow money on a secured or unsecured basis and use Collateral of the Credit Parties directly in carrying on the Credit Parties’
business or as security for loans or advances to enable the Receiver to carry on the Credit Parties’ business or otherwise, as such Receiver shall, in its discretion, determine. Except as may be otherwise directed by Agent, all money received
from time to time by such Receiver in carrying out his/her appointment shall be received in trust for and paid over to Agent. Every such Receiver may, in the discretion of Agent, be vested with all or any of the rights and powers of Agent and the
Lenders. Agent may, either directly or through its nominees, exercise any or all powers and rights given to a Receiver by virtue of the foregoing provisions of this paragraph. 

11.2. Agent’s Discretion. Agent shall have the right in its sole discretion to determine which rights, Liens, security interests
or remedies Agent may at any time pursue, relinquish, subordinate, or modify, which procedures, timing and methodologies to employ, and what any other action to take with respect to any or all of the Collateral and in what order, thereto and such
determination will not in any way modify or affect any of Agent’s or Lenders’ rights hereunder as against Borrowers or each other. 

11.3. Setoff. 
 (a)
Subject to Section 14.13, in addition to any other rights which Agent or any Lender may have under Applicable Law, upon the occurrence and during the continuance of an Event of Default hereunder, Agent and such Lender shall have a right,
immediately and without notice of any kind, to apply any Borrower’s or Sand Tiger’s (as applicable) property held by Agent and such Lender or any of their Affiliates to reduce the Obligations or Sand Tiger’s Obligations, in the case
of Sand Tiger, and to exercise any and all rights of setoff which may be available to Agent and such Lender with respect to any deposits held by Agent or such Lender. 

(b) If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of any of
the Advances made by it resulting in such Lender’s receiving payment of a proportion of the aggregate amount of such Advances, greater than its pro rata share thereof as provided herein, then the Lender receiving such greater
proportion shall (a) notify the Agent in writing of such fact, and (b) purchase (for cash at face value) a pro rata portion of the outstanding Advances (and participation interests in Letters of Credit) of each of the other Lenders (and
such Lenders hereby agree to sell and to take all such further action to effectuate such sale) such that each Lender shall hold its pro rata share of the outstanding Advances (and participation interests) after giving effect to such purchase. 

(c) Each Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable Law, that any Lender acquiring
a participation pursuant to the foregoing arrangements may exercise against such Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such
participation. 

  
 122 

[Mammoth] Credit Agreement 

 11.4. Rights and Remedies not Exclusive. The enumeration of the foregoing rights and
remedies is not intended to be exhaustive and the exercise of any rights or remedy shall not preclude the exercise of any other right or remedies provided for herein or otherwise provided by law, all of which shall be cumulative and not alternative.

 11.5. Allocation of Payments After Event of Default. Notwithstanding any other provisions of this Agreement to the contrary, after
the occurrence and during the continuance of an Event of Default, all amounts collected or received by Agent on account of the Obligations (including without limitation any amounts on account of any of Cash Management Liabilities or Hedge
Liabilities), or in respect of the Collateral may, at Agent’s discretion, be paid over or delivered as follows: 
 FIRST, to the
payment of all reasonable out-of-pocket costs and expenses (including reasonable attorneys’ fees) of Agent in connection with enforcing its rights and the rights of Lenders under this Agreement and the Other Documents, and any Out-of-Formula

 FOURTH, to the

 FIFTH, to the payment of the outstanding

 SIXTH, to the payment of all Obligations arising under this Agreement and
the Other Documents consisting of accrued fees and interest (other than interest in respect of Swing Loans paid pursuant to clause FOURTH above); 

SEVENTH, to the payment of the outstanding principal amount of the Obligations (other than principal in respect of Swing Loans paid pursuant
to clause FIFTH above) arising under this Agreement (other than Cash Management Liabilities and Hedge Liabilities) (including the payment or cash collateralization of any outstanding Letters of Credit in accordance with Section 3.2(b) hereof).

 EIGHTH, to all other Obligations arising under this Agreement (other than Cash Management Liabilities and Hedge Liabilities) which shall
have become due and payable (hereunder, under the Other Documents or otherwise) and not repaid pursuant to clauses “FIRST” through “SEVENTH” above; 

  
 123 

[Mammoth] Credit Agreement 

 NINTH, to any Cash Management Liabilities and Hedge Liabilities which shall have become due and

 TENTH, to all other
Obligations which shall have become due and payable and not repaid pursuant to clauses “FIRST” through “NINTH”; and

In carrying out the foregoing, (i) amounts received shall be applied in the numerical order provided until exhausted prior to application
to the next succeeding category; (ii) each of the Lenders shall receive (so long as it is not a Defaulting Lender) an amount equal to its pro rata share (based on the proportion that the then outstanding Advances held by such Lender bears to
the aggregate then outstanding Advances) of amounts available to be applied pursuant to clauses “SIXTH”, “SEVENTH”, “EIGHTH” and “TENTH” above; and, with respect to clause “NINTH” above, an amount
equal to its pro rata share (based on the proportion that the then outstanding Cash Management Liabilities and Hedge Liabilities held by such Lender bears to the aggregate then outstanding Cash Management Liabilities and Hedge Liabilities; and
(iii) notwithstanding anything to the contrary in this Section 11.5, no Swap Obligations of any Non-Qualifying Party shall be paid with amounts received from such Non-Qualifying Party under its Guaranty (including sums received as a result
of the exercise of remedies with respect to such Guaranty) or from the proceeds of such Non-Qualifying Party’s Collateral if such Swap Obligations would constitute Excluded Hedge Liabilities, provided, however, that to the extent possible
appropriate adjustments shall be made with respect to payments and/or the proceeds of Collateral from other Borrowers and/or Guarantors that are Eligible Contract Participants with respect to such Swap Obligations to preserve the allocation to
Obligations otherwise set forth above in this Section 11.5; and (iv) to the extent that any amounts available for distribution pursuant to clause “SEVENTH” above are attributable to the issued but undrawn amount of outstanding
Letters of Credit, such amounts shall be held by Agent as cash collateral for the Letters of Credit pursuant to Section 3.2(b) hereof and applied (A) first, to reimburse Issuer from time to time for any drawings under such Letters of
Credit and (B) then, following the expiration of all Letters of Credit, to all other obligations of the types described in clauses “SEVENTH,” “EIGHTH”, “NINTH”, and “TENTH” above in the manner provided in

 124 

[Mammoth] Credit Agreement

ACTION OR CAUSE OF ACTION (A) ARISING UNDER THIS AGREEMENT, ANY OTHER DOCUMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR (B) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE

	XIII.	EFFECTIVE DATE AND TERMINATION. 

 13.1. Term. This Agreement, which shall inure to the
benefit of and shall be binding upon the respective successors and permitted assigns of each Borrower, Agent and each Lender, shall become effective on the date hereof and shall continue in full force and effect until November 25, 2019 (the
“Term”) unless sooner terminated as herein provided. Borrowers may terminate this Agreement at any time upon five (5) Business Days prior written notice to Agent upon payment in full of the Obligations (other than contingent
indemnity claims not yet asserted or threatened). Each notice delivered by the Borrowing Agent under this Section 13.1 may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be
revoked by the Borrowers (by notice to the Agent on or prior to the specified effective date) if such condition is not satisfied. In the event that the Maximum Revolving Advance Amount (whether voluntarily or involuntarily) is permanently reduced or
terminated on or prior to the date immediately preceding the first anniversary of the Closing Date, Borrowers (other than Sand Tiger) shall concurrently pay to the Agent, for the benefit of Lenders on a pro rata basis, a termination or reduction fee
in an amount equal to one percent (1%) of the amount that the Maximum Revolving Advance Amount is so reduced or terminated below $170,000,000.

transactions entered into, rights or interests created and Obligations have been fully and indefeasibly paid, disposed of, concluded or liquidated. The security interests, Liens and rights granted to Agent and Lenders hereunder and the financing
statements filed hereunder shall continue in full force and effect, 

  
 125 

[Mammoth] Credit Agreement 

 
notwithstanding the termination of this Agreement or the fact that Borrowers’ Accounts may from time to time be temporarily in a zero or credit position, until all of the Obligations of each
Borrower have been indefeasibly paid and performed in full after the termination of this Agreement or each Borrower has furnished Agent and Lenders with an indemnification satisfactory to Agent and Lenders with respect thereto. Accordingly, each
Borrower waives any rights which it may have under the Uniform Commercial Code or PPSA to demand the filing of termination statements with respect to the Collateral, and Agent shall not be required to send such termination statements to each
Borrower, or to file them with any filing office, unless and until this Agreement shall have been terminated in accordance with its terms and all Obligations have been indefeasibly paid in full in immediately available funds. All representations,
warranties, covenants, waivers and agreements contained herein shall survive termination hereof until all Obligations are indefeasibly paid and performed in full. 
  

	XIV.	REGARDING AGENT. 

 14.1. Appointment. Each Lender hereby designates PNC to act as Agent
for such Lender under this Agreement and the Other Documents. Each Lender hereby irrevocably authorizes Agent to take such action on its behalf under the provisions of this Agreement and the Other Documents and to exercise such powers and to perform
such duties hereunder and thereunder as are specifically delegated to or required of Agent by the terms hereof and thereof and such other powers as are reasonably incidental thereto and Agent shall hold all Collateral, payments of principal and
interest, fees (except the fees set forth in Sections 2.8(b) and the Fee Letter), charges and collections received pursuant to this Agreement, for the ratable benefit of Lenders. Agent may perform any of its duties hereunder by or through its
agents or employees. As to any matters not expressly provided for by this Agreement (including collection of the Note) Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting
(and shall be fully protected in so acting or refraining from acting) upon the instructions of Required Lenders, and such instructions shall be binding; provided, however, that Agent shall not be required to take any action which, in Agent’s
discretion, exposes Agent to liability or which is contrary to this Agreement or the Other Documents or Applicable Law unless Agent is furnished with an indemnification reasonably satisfactory to Agent with respect thereto. 

14.2. Nature of Duties. Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and the Other
Documents. Neither Agent nor any of its officers, directors, employees or agents shall be (i) liable for any action taken or omitted by them as such hereunder or in connection herewith, unless caused by their gross (not mere) negligence or
willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment), or (ii) responsible in any manner for any recitals, statements, representations or warranties made by any Borrower or any officer
thereof contained in this Agreement, or in any of the Other Documents or in any certificate, report, statement or other document referred to or provided for in, or received by Agent under or in connection with, this Agreement or any of the Other
Documents or for the value, validity, effectiveness, genuineness, due execution, enforceability or sufficiency of this Agreement, or any of the Other Documents or for any failure of any Borrower to perform its obligations hereunder or under any
Other Document. Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any of the

  
 126 

[Mammoth] Credit Agreement 

 
Other Documents, or to inspect the properties, books or records of any Borrower. The duties of Agent as respects the Advances to Borrowers shall be mechanical and administrative in nature; Agent
shall not have by reason of this Agreement a fiduciary relationship in respect of any Lender; and nothing in this Agreement, expressed or implied, is intended to or shall be so construed as to impose upon Agent any obligations in respect of this
Agreement or the transactions described herein except as expressly set forth herein. 
 Without limiting the foregoing, the Agent shall not
be required to act hereunder or to advance its own funds or otherwise incur any financial liability in the performance of its duties or the exercise of its rights hereunder and under any Other Document, and shall in all cases be fully justified in
failing or refusing to act hereunder unless it shall receive further assurances to its satisfaction from the Lenders of their indemnification obligations under and in accordance with the provisions of Section 14.7 against any and all liability
and expense that may be incurred by it by reason of taking or continuing to take or refraining from taking any such action. The Agent shall be fully justified in requesting direction from the Required Lenders in the event this Agreement or any Other
Document is silent or vague with respect to Agent’s duties, rights or obligations. The Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders or (ii) in the
absence of its own gross negligence or willful misconduct, as determined by a court of competent jurisdiction in a final and non-appealable decision. In no instance shall the Agent have any liability for special, consequential or indirect damages or
penalties (including lost profits) even if it has been advised of the likelihood of the same. Without prejudice to the generality of the foregoing, the Agent shall not be liable for any damage or loss resulting from or caused by events or
circumstances beyond the Agent’s reasonable control, including nationalization, expropriation, currency restrictions, the interruption, disruption or suspension of the normal procedures and practices of any securities market, power, mechanical,
communications or other technological failures or interruptions, computer viruses or the like, acts of war or terrorism, riots, revolution, acts of God, work stoppages, strikes, national disasters of any kind, or other similar events or acts. 

14.3. Lack of Reliance on Agent. Independently and without reliance upon Agent or any other Lender, each Lender has made and shall
continue to make (i) its own independent investigation of the financial condition and affairs of each Credit Party in connection with the making and the continuance of the Advances hereunder and the taking or not taking of any action in
connection herewith, and (ii) its own appraisal of the creditworthiness of each Credit Party. Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with
respect thereto, whether coming into its possession before making of the Advances or at any time or times thereafter except as shall be provided by any Credit Party pursuant to the terms hereof. Agent shall not be responsible to any Lender for any
recitals, statements, information, representations or warranties herein or in any agreement, document, certificate or a statement delivered in connection with or for the execution, effectiveness, genuineness, validity, enforceability,
collectability, sufficiency or value of this Agreement or any Other Document or any other instrument or document furnished pursuant hereto or thereto, or of the financial condition of any Credit Party, or be required to make any inquiry concerning
either the performance or observance of any of the terms, provisions or conditions of this Agreement, the Note, the Other Documents or the financial condition of any Borrower, or the existence of any Event of Default or any Default.

[Mammoth] Credit Agreement 

 14.4. Resignation of Agent; Successor Agent. Agent may resign on sixty (60) days
written notice to each Lender and Borrowing Agent and upon such resignation, Required Lenders will promptly designate a successor Agent reasonably satisfactory to Borrowers (provided that no such approval by Borrowers shall be required (i) in
any case where the successor Agent is one of the Lenders or (ii) after the occurrence and during the continuance of any Event of Default). Any such successor Agent shall succeed to the rights, powers and duties of Agent, and shall in particular
succeed to all of Agent’s right, title and interest in and to all of the Liens in the Collateral securing the Obligations created hereunder or any Other Document (including the Pledge Agreement and all account control agreements), and the term
“Agent” shall mean such successor agent effective upon its appointment, and the former Agent’s rights, powers and duties as Agent shall be terminated, without any other or further act or deed on the part of such former Agent. However,
notwithstanding the foregoing, if at the time of the effectiveness of the new Agent’s appointment, any further actions need to be taken in order to provide for the legally binding and valid transfer of any Liens in the Collateral from former
Agent to new Agent and/or for the perfection of any Liens in the Collateral as held by new Agent or it is otherwise not then possible for new Agent to become the holder of a fully valid, enforceable and perfected Lien as to any of the Collateral,
former Agent shall continue to hold such Liens solely as agent for perfection of such Liens on behalf of new Agent until such time as new Agent can obtain a fully valid, enforceable and perfected Lien on all Collateral, provided that Agent shall not
be required to or have any liability or responsibility to take any further actions after such date as such agent for perfection to continue the perfection of any such Liens (other than to forego from taking any affirmative action to release any such
Liens). After any Agent’s resignation as Agent, the provisions of this Article XIV, and any indemnification rights under this Agreement, including without limitation, rights arising under Section 16.5 hereof, shall inure to its benefit as
to any actions taken or omitted to be taken by it while it was Agent under this Agreement (and in the event resigning Agent continues to hold any Liens pursuant to the provisions of the immediately preceding sentence, the provisions of this Article
XIV and any indemnification rights under this Agreement, including without limitation, rights arising under Section 16.5 hereof, shall inure to its benefit as to any actions taken or omitted to be taken by it in connection with such Liens).

 14.5. Certain Rights of Agent. If Agent shall request instructions from Lenders with respect to any act or action (including
failure to act) in connection with this Agreement or any Other Document, Agent shall be entitled to refrain from such act or taking such action unless and until Agent shall have received instructions from Required Lenders; and Agent shall not incur
liability to any Person by reason of so refraining. Without limiting the foregoing, Lenders shall not have any right of action whatsoever against Agent as a result of its acting or refraining from acting hereunder in accordance with the instructions
of Required Lenders. 
 14.6. Reliance. Agent shall be entitled to rely, and shall be fully protected in relying, upon any note,
writing, resolution, notice, statement, certificate, telex, teletype or telecopier message, cablegram, order or other document or telephone message believed by it to be genuine and correct and to have been signed, sent or made by the proper person
or entity, and, with respect to all legal matters pertaining to this Agreement and the Other Documents and its duties hereunder, upon advice of counsel selected by it. Agent may employ agents and attorneys-in-fact and shall not be liable for the
acts, omissions, negligence or misconduct of any such agents or attorneys-in-fact selected by Agent with reasonable care. In determining compliance with any 

  
 128 

[Mammoth] Credit Agreement 

 
condition hereunder, the Agent shall be entitled to receive, and shall not incur any liability for relying upon, a certificate of an Authorized Officer or an opinion of counsel or both certifying
as to compliance with such condition. The Agent may consult with legal counsel (who may be counsel for the Credit Parties or any Lender), independent accountants and other experts selected by it, and shall not be liable for any action taken or not
taken by it in accordance with the advice of any such counsel, accountants or experts. 
 14.7. Notice of Default. Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder or under the Other Documents, unless Agent has received notice from a Lender or Borrowing Agent referring to this Agreement or the Other Documents,
describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that Agent receives such a notice, Agent shall give notice thereof to Lenders. Agent shall take such action with respect to
such Default or Event of Default as shall be reasonably directed by Required Lenders; provided, that, unless and until Agent shall have received such directions, Agent may (but shall not be obligated to) take such action, or refrain from taking such
action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of Lenders. 
 14.8.
Indemnification. To the extent Agent is not reimbursed and indemnified by Borrowers, each Lender will reimburse and indemnify Agent in proportion to its respective portion of the outstanding Advances and its respective Participation
Commitments in the outstanding Letters of Credit and outstanding Swing Loans (or, if no Advances are outstanding, pro rata according to the percentage that its Commitment Amount constitutes of the total aggregate Commitment Amounts), from and
against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against Agent in performing its
duties hereunder, or in any way relating to or arising out of this Agreement or any Other Document; provided that Lenders shall not be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from Agent’s gross (not mere) negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment). 

14.9. Agent in its Individual Capacity. With respect to the obligation of Agent to lend under this Agreement, the Advances made by it
shall have the same rights and powers hereunder as any other Lender and as if it were not performing the duties as Agent specified herein; and the term “Lender” or any similar term shall, unless the context clearly otherwise indicates,
include Agent in its individual capacity as a Lender. Agent may engage in business with any Borrower as if it were not performing the duties specified herein, and may accept fees and other consideration from any Borrower for services in connection
with this Agreement or otherwise without having to account for the same to Lenders. 
 14.10. Delivery of Documents. To the extent
Agent receives financial statements required under Sections 9.7, 9.8, 9.9, 9.12 and 9.13 or Borrowing Base Certificates from any Borrower pursuant to the terms of this Agreement which any Borrower is not obligated to deliver to each Lender, Agent
will promptly furnish such documents and information to Lenders. 

  
 129 

[Mammoth] Credit Agreement 

 14.11. Borrowers’ Undertaking to Agent. Without prejudice to their respective
obligations to Lenders under the other provisions of this Agreement, each Borrower hereby undertakes with Agent to pay to Agent from time to time on demand all amounts from time to time due and payable by it for the account of Agent or Lenders or
any of them pursuant to this Agreement to the extent not already paid. Any payment made pursuant to any such demand shall pro tanto satisfy the relevant Borrower’s obligations to make payments for the account of Lenders or the relevant one or
more of them pursuant to this Agreement. 
 14.12. No Reliance on Agent’s Customer Identification Program. To the extent the
Advances or this Agreement is, or becomes, syndicated in cooperation with other Lenders, each Lender acknowledges and agrees that neither such Lender, nor any of its Affiliates, participants or assignees, may rely on Agent to carry out such
Lender’s, Affiliate’s, participant’s or assignee’s customer identification program, or other obligations required or imposed under or pursuant to the USA PATRIOT Act or the regulations thereunder, including the regulations
contained in 31 CFR 103.121 (as hereafter amended or replaced, the “CIP Regulations”), or any other Anti-Terrorism Law, including any programs involving any of the following items relating to
or in connection with any of Borrowers, their Affiliates or their agents, the Other Documents or the transactions hereunder or contemplated hereby: (i) any identity verification procedures, (ii) any recordkeeping, (iii) comparisons
with government lists, (iv) customer notices or (v) other procedures required under the CIP Regulations or such Anti-Terrorism Laws. 

14.13. Other Agreements. Each of the Lenders agrees that it shall not, without the express consent of Agent, and that it shall, to the
extent it is lawfully entitled to do so, upon the request of Agent, set off against the Obligations, any amounts owing by such Lender to any Borrower or any deposit accounts of any Borrower now or hereafter maintained with such Lender. Anything in
this Agreement to the contrary notwithstanding, each of the Lenders further agrees that it shall not, unless specifically requested to do so by Agent, take any action to protect or enforce its rights arising out of this Agreement or the Other
Documents, it being the intent of Lenders that any such action to protect or enforce rights under this Agreement and the Other Documents shall be taken in concert and at the direction or with the consent of Agent or Required Lenders. 

 

	XV.	BORROWING AGENCY. 

 15.1. Borrowing Agency Provisions. 

(a) Each Borrower hereby irrevocably designates Borrowing Agent to be its attorney and agent and in such capacity to (i) borrow,
(ii) request advances, (iii) request the issuance of Letters of Credit, (iv) sign and endorse notes, (v) execute and deliver all instruments, documents, applications, security agreements, reimbursement agreements and letter of
credit agreements for Letters of Credit and all other certificates, notice, writings and further assurances now or hereafter required hereunder, (vi) make elections regarding interest rates, (vii) give instructions regarding Letters of
Credit and agree with Issuer upon any amendment, extension or renewal of any Letter of Credit and (viii) otherwise take action under and in connection with this Agreement and the Other Documents, all on behalf of and in the name such Borrower
or Borrowers, and hereby authorizes Agent to pay over or credit all loan proceeds hereunder in accordance with the request of Borrowing Agent. 

  
 130 

[Mammoth] Credit Agreement 

 (b) The handling of this credit facility as a co-borrowing facility with a borrowing agent in the
manner set forth in this Agreement is solely as an accommodation to Borrowers and at their request. Neither Agent nor any Lender shall incur liability to Borrowers as a result thereof. To induce Agent and Lenders to do so and in consideration
thereof, each Borrower hereby indemnifies Agent and each Lender and holds Agent and each Lender harmless from and against any and all liabilities, expenses, losses, damages and claims of damage or injury asserted against Agent or any Lender by any
Person arising from or incurred by reason of the handling of the financing arrangements of Borrowers as provided herein, reliance by Agent or any Lender on any request or instruction from Borrowing Agent or any other action taken by Agent or any
Lender with respect to this Section 15.1 except due to willful misconduct or gross (not mere) negligence by the indemnified party (as determined by a court of competent jurisdiction in a final and non-appealable judgment), and except that, Sand
Tiger shall only be liable for the Sand Tiger Obligations. 
 (c) All Obligations shall be joint and several (provided, Sand Tiger
shall only be liable for the Sand Tiger Obligations), and each Borrower shall make payment upon the maturity of the Obligations by acceleration or otherwise, and such obligation and liability on the part of each Borrower shall in no way be affected
by any extensions, renewals and forbearance granted by Agent or any Lender to any Borrower, failure of Agent or any Lender to give any Borrower notice of borrowing or any other notice, any failure of Agent or any Lender to pursue or preserve its
rights against any Borrower, the release by Agent or any Lender of any Collateral now or thereafter acquired from any Borrower, and such agreement by each Borrower to pay upon any notice issued pursuant thereto is unconditional and unaffected by
prior recourse by Agent or any Lender to the other Borrowers or any Collateral for such Borrower’s Obligations or the lack thereof. Each Borrower waives all suretyship defenses. 

15.2. Waiver of Subrogation. Each Borrower expressly waives any and all rights of subrogation, reimbursement, indemnity, exoneration,
contribution of any other claim which such Borrower may now or hereafter have against any other Borrower or any other Person directly or contingently liable for the Obligations hereunder, or against or with respect to any other Borrowers’
property (including, without limitation, any property which is Collateral for the Obligations), arising from the existence or performance of this Agreement, until termination of this Agreement and repayment in full of the Obligations (other than
contingent indemnification obligations in respect of which no assertion of liability has been made). 
 15.3. Common Enterprise. The
successful operation and condition of each of the Borrowers (other than Sand Tiger) is dependent on the continued successful performance of the functions of the group of Borrowers as a whole and the successful operation of each Borrower is dependent
on the successful performance and operation of each other Borrower. Each of the Borrowers expects to derive benefit (and its board of directors or other governing body has determined that it may reasonably be expected to derive benefit), directly
and indirectly, from successful operations of Holdings and each of the other Borrowers. Each Borrower expects to derive benefit (and the boards of directors or other governing body of each such Borrower have determined that it may reasonably be
expected to derive benefit), directly and indirectly, from the credit extended by the Lenders to the Borrowers hereunder, both in their separate capacities and as members of the group of companies. Each Borrower has determined that execution,
delivery, and performance of this Agreement and any Other Documents to be executed by such Borrower is within its corporate purpose, will be of direct and indirect benefit to such Borrower, and is in its best interest.

[Mammoth] Credit Agreement 

	XVI.	MISCELLANEOUS. 

 16.1. Governing Law. This Agreement and each Other Document (unless and
except to the extent expressly provided otherwise in any such Other Document), and all matters relating hereto or thereto or arising herefrom or therefrom (whether arising under contract law, tort law or otherwise) shall, in accordance with
Section 5-1401 of the General Obligations Law of the State of New York, be governed by and construed in accordance with the laws of the State of New York applied to contracts to be performed wholly within the State of New York. Any judicial
proceeding brought by or against any Borrower with respect to any of the Obligations, this Agreement, the Other Documents or any related agreement may be brought in any court of competent jurisdiction in the State of New York, United States of
America, and, by execution and delivery of this Agreement, each Borrower accepts for itself and in connection with its properties, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts, and irrevocably agrees to be
bound by any judgment rendered thereby in connection with this Agreement, but with respect to Sand Tiger only, the Agent and Lenders shall not be precluded from initiating any proceeding against it in the courts of the Province of Alberta, Canada in
their sole discretion. Each Borrower hereby waives personal service of any and all process upon it and consents that all such service of process may be made by certified or registered mail (return receipt requested) directed to Borrowing Agent at
its address set forth in Section 16.6 and service so made shall be deemed completed five (5) days after the same shall have been so deposited in the mails of the United States of America, or, at Agent’s option, by service upon
Borrowing Agent which each Borrower irrevocably appoints as such Borrower’s Agent for the purpose of accepting service within the State of New York. Nothing herein shall affect the right to serve process in any manner permitted by law or shall
limit the right of Agent or any Lender to bring proceedings against any Borrower in the courts of any other jurisdiction. Each Borrower waives any objection to jurisdiction and venue of any action instituted hereunder and shall not assert any
defense based on lack of jurisdiction or venue or based upon forum non conveniens. Each Borrower waives the right to remove any judicial proceeding brought against such Borrower in any state court to any federal court. Any judicial proceeding by any
Borrower against Agent or any Lender involving, directly or indirectly, any matter or claim in any way arising out of, related to or connected with this Agreement or any related agreement, shall be brought only in a federal or state court located in
the County of New York, State of New York (or, with respect to Sand Tiger) the Province of Alberta. 
 16.2. Entire Understanding.

 (a) THIS AGREEMENT AND THE DOCUMENTS EXECUTED CONCURRENTLY HEREWITH CONTAIN THE ENTIRE UNDERSTANDING BETWEEN EACH BORROWER, AGENT AND EACH

 132 

[Mammoth] Credit Agreement 

 
AGENT’S AND EACH LENDER’S RESPECTIVE OFFICERS. Neither this Agreement nor any portion or provisions hereof may be changed, modified, amended, waived, supplemented, discharged, cancelled
or terminated orally or by any course of dealing, or in any manner other than by an agreement in writing, signed by the party to be charged. Notwithstanding the foregoing, Agent may modify this Agreement or any of the Other Documents for the
purposes of completing missing content or correcting erroneous content of an administrative nature, without the need for a written amendment, provided that the Agent shall send a copy of any such modification to the Borrowers and each Lender (which
copy may be provided by electronic mail). Each Borrower acknowledges that it has been advised by counsel in connection with the execution of this Agreement and Other Documents and is not relying upon oral representations or statements inconsistent
with the terms and provisions of this Agreement. 
 (b) Required Lenders, Agent with the consent in writing of Required Lenders, and
Borrowers may, subject to the provisions of this Section 16.2(b), from time to time enter into written supplemental agreements to this Agreement or the Other Documents (other than with respect to Cash Management Products and Services and
Lender-Provided Hedges, other similar agreements or the Fee Letter, which shall require only the consent of the parties thereto) executed by the applicable Credit Parties, for the purpose of adding or deleting any provisions or otherwise changing,
varying or waiving in any manner the rights of Lenders, Agent or Borrowers thereunder or the conditions, provisions or terms thereof or waiving any Event of Default thereunder, but only to the extent specified in such written agreements; provided,
however, that no such supplemental agreement shall: 
 (i) increase the Commitment Percentage, or the maximum dollar amount of the
Commitment Amount of any Lender without the consent of such Lender directly affected thereby; 
 (ii) whether or not any Advances are
outstanding, extend the Term or the time for payment of principal or interest of any Advance (excluding the due date of any mandatory prepayment of an Advance), or any fee payable to any Lender, or reduce the principal amount of or the rate of
interest borne by any Advances or reduce any fee payable to any Lender, without the consent of each Lender directly affected thereby (except that Required Lenders may elect to waive or rescind any imposition of the Default Rate under
Section 3.1 or of default rates of Letter of Credit fees under Section 3.2 (unless imposed by Agent)); 
 (iii) except in
connection with any increase pursuant to Section 2.24 hereof, increase the Maximum Revolving Advance Amount without the consent of each Lender directly affected thereby; 

(iv) alter the definition of the term Required Lenders or Supermajority Lenders or alter, amend or modify this Section 16.2(b) without
the consent of all Lenders; 
 (v) alter, amend or modify the provisions of Section 11.5 without the consent of all Lenders directly

 133 

[Mammoth] Credit Agreement 

 (vii) change the rights and duties of Agent without the consent of Supermajority Lenders; 

(viii) subject to clauses (e) and (f) below, voluntarily permit any Revolving Advance (inclusive of amounts outstanding pursuant to
clause (f) below) to be made if after giving effect thereto the total of Revolving Advances outstanding hereunder would exceed the Formula Amount for more than thirty (30) consecutive Business Days or exceed the lesser of
(x) one hundred and ten percent (110%) of the Formula Amount or (y) the Maximum Revolving Advance Amount, in each case, without the consent of each Lender directly affected thereby; 

(ix) increase the Advance Rates above the Advance Rates in effect on the Closing Date without the consent of Supermajority Lenders; 

(x) modify the definitions of Eligible Receivables, Eligible Equipment, Eligible Inventory, Eligible In-Transit Inventory, Eligible Unbilled
Receivables, Eligible Equipment Sublimit, Letter of Credit Sublimit or the Maximum Swing Loan Advance Amount in effect on the Closing Date without the consent of Supermajority Lenders; 

(xi) release any Guarantor or Borrower without the consent of all Lenders; or 

(xii) increase the amount of proceeds of direct Revolving Advances that may be made available, and remain outstanding on any day, to Sand
Tiger without the consent of each Lender directly affected thereby. 
 (c) Any such supplemental agreement shall apply equally to each
Lender and shall be binding upon Borrowers, Lenders and Agent and all future holders of the Obligations. In the case of any waiver, Borrowers, Agent and Lenders shall be restored to their former positions and rights, and any Event of Default waived
shall be deemed to be cured and not continuing, but no waiver of a specific Event of Default shall extend to any subsequent Event of Default (whether or not the subsequent Event of Default is the same as the Event of Default which was waived), or
impair any right consequent thereon. 
 (d) In the event that Agent requests the consent of a Lender pursuant to this Section 16.2 and
such consent is denied, then Agent may, at its option, require such Lender to assign its interest in the Advances to Agent or to another Lender or to any other Person designated by Agent (the “Designated Lender”), for a price equal
to (i) the then outstanding principal amount thereof plus (ii) accrued and unpaid interest and fees due such Lender, which interest and fees shall be paid when collected from Borrowers. In the event Agent elects to require any Lender to
assign its interest to Agent or to the Designated Lender, Agent will so notify such Lender in writing within forty five (45) days following such Lender’s denial, and such Lender will assign its interest to Agent or the Designated Lender no
later than five (5) days following receipt of such notice pursuant to a Commitment Transfer Supplement executed by such Lender, Agent or the Designated Lender, as appropriate, and Agent. 

  
 134 

[Mammoth] Credit Agreement 

 (e) Notwithstanding (i) the existence of a Default or an Event of Default, (ii) that
any of the other applicable conditions precedent set forth in Section 8.2 hereof have not been satisfied or (iii) any other provision of this Agreement, Agent may at its discretion and without the consent of the Required Lenders,
voluntarily permit the outstanding Revolving Advances at any time to exceed the Formula Amount by up to ten percent (10%) of the Formula Amount for up to thirty (30) consecutive Business Days (the “Out-of-Formula Loans”);
provided, that, such outstanding Advances do not exceed the Maximum Revolving Advance Amount. If Agent is willing in its sole and absolute discretion to make such Out-of-Formula Loans, Lenders holding the Commitments shall be obligated to
fund such Out-of-Formula Loans in accordance with their respective Commitment Percentages, and such Out-of-Formula Loans shall be payable on demand and shall bear interest at the Default Rate for Revolving Advances consisting of Domestic Rate Loans;
provided that, if Agent does permit Out-of-Formula Loans, neither Agent nor Lenders shall be deemed thereby to have changed the limits of Section 2.1(a) nor shall any Lender be obligated to fund Revolving Advances in excess of its
Commitment Amount. For purposes of this paragraph, the discretion granted to Agent hereunder shall not preclude involuntary overadvances that may result from time to time due to the fact that the Formula Amount was unintentionally exceeded for any
reason, including, but not limited to, Collateral previously deemed to be either “Eligible Receivables”, “Eligible Equipment”, “Eligible Inventory”, “Eligible In-Transit Inventory” or “Eligible Unbilled
Receivables”, as applicable, becomes ineligible, collections of Receivables applied to reduce outstanding Revolving Advances are thereafter returned for insufficient funds or overadvances are made to protect or preserve the Collateral. In the
event Agent involuntarily permits the outstanding Revolving Advances to exceed the Formula Amount by more than ten percent (10%), Agent shall use its efforts to have Borrowers decrease such excess in as expeditious a manner as is practicable under
the circumstances and not inconsistent with the reason for such excess. Revolving Advances made after Agent has determined the existence of involuntary overadvances shall be deemed to be involuntary overadvances and shall be decreased in accordance
with the preceding sentence. To the extent any Out-of-Formula Loans are not actually funded by the other Lenders as provided for in this Section 16.2(e), Agent may elect in its discretion to fund such Out-of-Formula Loans and any such
Out-of-Formula Loans so funded by Agent shall be deemed to be Revolving Advances made by and owing to Agent, and Agent shall be entitled to all rights (including accrual of interest) and remedies of a Lender holding a Commitment under this Agreement
and the Other Documents with respect to such Revolving Advances. 
 (f) In addition to (and not in substitution of) the discretionary
Revolving Advances permitted above in Section 16.2, the Agent is hereby authorized by Borrowers and the Lenders, at any time in the Agent’s sole discretion, regardless of (i) the existence of a Default or an Event of Default,
(ii) whether any of the other applicable conditions precedent set forth in Section 8.2 hereof have not been satisfied or the commitments of Lenders to make Revolving Advances hereunder have been terminated for any reason, or (iii) any
other contrary provision of this Agreement, to make Revolving Advances (“Protective Advances”) to Borrowers, subject to Section 2.1(a), on behalf of the Lenders which Agent, in its reasonable business judgment, deems
necessary or desirable (a) to preserve or protect the Collateral, or any portion thereof, (b) to enhance the likelihood of, or maximize the amount of, repayment of the Advances and other Obligations, or (c) to pay any other amount
chargeable to Borrowers pursuant to the terms of this Agreement; provided, that the Protective Advances made hereunder shall not exceed, in the 

  
 135 

[Mammoth] Credit Agreement 

 
aggregate, 10% of the Maximum Revolving Advance Amount; and provided further that at any time after giving effect to any such Protective Advances, the outstanding Revolving Advances, Swing
Loans Maximum Undrawn Amount of all outstanding Letters of Credit do not exceed the Maximum Revolving Advance Amount. The Lenders holding the Commitments shall be obligated to fund such Protective Advances and effect a settlement with Agent
therefore upon demand of Agent in accordance with their respective Commitment Percentages. To the extent any Protective Advances are not actually funded by the other Lenders as provided for in this Section 16.2(f), any such Protective Advances
funded by Agent shall be deemed to be Revolving Advances made by and owing to Agent, and Agent shall be entitled to all rights (including accrual of interest) and remedies of a Lender holding a Commitment under this Agreement and the Other Documents
with respect to such Revolving Advances. 
 16.3. Successors and Assigns; Participations; New Lenders. 

(a) This Agreement shall be binding upon and inure to the benefit of each Borrower, Agent, each Lender, all future holders of the Obligations
and their respective successors and permitted assigns, except that Borrowers may not assign or transfer any of their rights or obligations under this Agreement without the prior written consent of Agent and each Lender. 

(b) Each Borrower acknowledges that in the regular course of commercial banking business one or more Lenders may at any time and from time to
time sell participating interests in the Advances (other than Swing Loans) to other financial institutions (each such transferee or purchaser of a participating interest, a “Participant”). Each Participant may exercise all rights of
payment (including rights of set-off to the extent permitted by Applicable Law) with respect to the portion of such Advances (other than Swing Loans) held by it or other Obligations payable hereunder as fully as if such Participant were the direct
holder thereof provided that Borrowers shall not be required to pay to any Participant more than the amount which it would have been required to pay to Lender which granted an interest in its Advances or other Obligations payable hereunder to such
Participant had such Lender retained such interest in the Advances hereunder or other Obligations payable hereunder and in no event shall Borrowers be required to pay any such amount arising from the same circumstances and with respect to the same
Advances or other Obligations payable hereunder to both such Lender and such Participant. Each Participant shall have the benefits of Section 3.10 hereof to the extent it complies with the provisions thereof. Each Borrower hereby grants to any
Participant a continuing security interest in any deposits, moneys or other property actually or constructively held by such Participant as security for the Participant’s interest in the Advances. No Lenders shall transfer, grant or sell any
participation under which the participant shall have the right to approve any amendment or waiver of this Agreement except to the extent such amendment or waiver would require the approval of all Lenders pursuant to Section 16.2(b). Each Lender
that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each
Participant’s interest in the Advances or other obligations under this Agreement and the Other Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of
the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under this Agreement or any Other Document) to any
Person except to the 

  
 136 

[Mammoth] Credit Agreement 

 
extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States
Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes
of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Agent (in its capacity as Agent) shall have no responsibility for maintaining a Participant Register. 

(c) Any Lender, with the consent of Agent and so long as no Event of Default then exists, Borrowing Agent (other than with respect to any
sale, assignment or transfer from any Lender to any Affiliate of such Lender or to any other Lender or any other Lender’s Affiliates), which shall not be unreasonably withheld, conditioned or delayed, may sell, assign or transfer all or any
part of its rights and obligations under or relating to Revolving Advances (other than Swing Loans) under this Agreement and the Other Documents to one or more additional banks or financial institutions and one or more additional banks or financial
institutions may commit to make Advances hereunder (each a “Purchasing Lender”), in minimum amounts of not less than $5,000,000, pursuant to a Commitment Transfer Supplement, executed by a Purchasing Lender, the transferor Lender,
and Agent and delivered to Agent for recording. Upon such execution, delivery, acceptance and recording, from and after the transfer effective date determined pursuant to such Commitment Transfer Supplement, (i) Purchasing Lender thereunder
shall be a party hereto and, to the extent provided in such Commitment Transfer Supplement, have the rights and obligations of a Lender thereunder with a Commitment Percentage as set forth therein, and (ii) the transferor Lender thereunder
shall, to the extent provided in such Commitment Transfer Supplement, be released from its obligations under this Agreement, the Commitment Transfer Supplement creating a novation for that purpose. Such Commitment Transfer Supplement shall be deemed
to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing Lender and the resulting adjustment of the Commitment Percentages arising from the purchase by such Purchasing Lender of all or a
portion of the rights and obligations of such transferor Lender under this Agreement and the Other Documents. Each Borrower hereby consents to the addition of such Purchasing Lender and the resulting adjustment of the Commitment Percentages arising
from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement and the Other Documents. Borrowers shall execute and deliver such further documents and do such further acts
and things in order to effectuate the foregoing. 
 (d) Any Lender, with the consent of Agent which shall not be unreasonably withheld or
delayed, may directly or indirectly sell, assign or transfer all or any portion of its rights and obligations under or relating to Revolving Advances under this Agreement and the Other Documents to an entity, whether a corporation, partnership,
trust, limited liability company or other entity that (i) is engaged in making, purchasing, holding or otherwise investing in bank loans and similar extensions of credit in the ordinary course of its business and (ii) is administered,
serviced or managed by the assigning Lender or an Affiliate of such Lender (a “Purchasing CLO” and together with each Participant and Purchasing Lender, each a “Transferee” and collectively the
“Transferees”), pursuant to a Commitment Transfer Supplement modified as appropriate to reflect the interest being assigned (“Modified Commitment Transfer Supplement”), executed by any intermediate purchaser, the
Purchasing CLO, the transferor Lender, and Agent as appropriate 

  
 137 

[Mammoth] Credit Agreement 

 
and delivered to Agent for recording. Upon such execution and delivery, from and after the transfer effective date determined pursuant to such Modified Commitment Transfer Supplement,
(i) Purchasing CLO thereunder shall be a party hereto and, to the extent provided in such Modified Commitment Transfer Supplement, have the rights and obligations of a Lender thereunder and (ii) the transferor Lender thereunder shall, to
the extent provided in such Modified Commitment Transfer Supplement, be released from its obligations under this Agreement, the Modified Commitment Transfer Supplement creating a novation for that purpose. Such Modified Commitment Transfer
Supplement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing CLO. Each Borrower hereby consents to the addition of such Purchasing CLO. Borrowers shall execute and
deliver such further documents and do such further acts and things in order to effectuate the foregoing. 
 (e) Agent shall maintain at its
address a copy of each Commitment Transfer Supplement and Modified Commitment Transfer Supplement delivered to it and a register (the “Register”) for the recordation of the names and addresses of each Lender and the outstanding
principal, accrued and unpaid interest and other fees due hereunder. The entries in the Register shall be conclusive, in the absence of manifest error, and each Borrower, Agent and Lenders may treat each Person whose name is recorded in the Register
as the owner of the Advance recorded therein for the purposes of this Agreement. The Register shall be available for inspection by any Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice. Agent shall
receive a fee in the amount of $3,500 payable by the applicable Purchasing Lender and/or Purchasing CLO upon the effective date of each transfer or assignment (other than to an intermediate purchaser) to such Purchasing Lender and/or Purchasing CLO.

in such Lender’s possession concerning such Borrower which has been delivered to such Lender by or on behalf of such Borrower pursuant to this Agreement or in connection with such Lender’s credit evaluation of such Borrower;
provided that the Transferee or prospective Transferee agrees to be bound by a non-disclosure agreement approved by Borrowers pursuant to which Borrowers are third party beneficiaries. 

(g) Notwithstanding anything to the contrary in this Section 16.3: (i) no sale, transfer or assignment of all or any portion of any
Lender’s rights and obligations under or relating to Loans under this Agreement shall be made to any Credit Party or any of their respective Affiliates. 

16.4. Application of Payments. Subject to application of payments and proceeds in accordance with Section 11.5, Agent shall have
the continuing and exclusive right to apply or reverse and re-apply any payment and any and all proceeds of Collateral to any portion of the Obligations or Sand Tiger’s Obligations, as applicable. To the extent that any Borrower makes a payment
or Agent or any Lender receives any payment or proceeds of the Collateral for any Borrower’s benefit, which are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in
possession, receiver, custodian or any other party under any bankruptcy law, common law or equitable cause, then, to such extent, the Obligations or part thereof intended to be satisfied shall be revived and continue as if such payment or proceeds
had not been received by Agent or such Lender.

rights and remedies of Agent, Issuer or any Lender under the Agreement and the Other Documents, (e) any threatened or actual imposition of fines or penalties, or disgorgement of benefits, for violation of any Anti-Terrorism Law by any Credit
Party, any Affiliate or Subsidiary of any Credit Party, (f) any claim, litigation, proceeding or investigation instituted or conducted by any Governmental Body or instrumentality or any other Person with respect to any aspect of, or any

and whether or not any Indemnified Party is a party thereto and (g) arising from or incurred by reason of the handling of the financing arrangements of Borrowers as provided in Section 15.1, reliance by Agent or any Lender on any request
or instruction from Borrowing Agent or any other action taken by Agent or any Lender with respect to Section 15.1; provided, however, notwithstanding anything in this Section 16.5, to the contrary, no Credit Party shall be
required to indemnify any Indemnified Party for any Claim which, in each case is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from (x) such Indemnified Party’s own gross negligence or
willful misconduct or that of its respective Affiliates or each of their respective officers, directors, employees, advisors and agents, (y) a claim brought by Borrower against an Indemnified Party for breach, in bad faith, of such Indemnified

in a final non-appealable judgment by a court of competent jurisdiction, (i) the Agent’s or its Affiliates’ respective capacities in connection with this Agreement or in fulfilling their roles as Agent, arranger or bookrunner or
(ii) any action or inaction of a Credit Party, any of its Subsidiaries or Affiliates. Without limiting the generality of any of the foregoing (but subject to clauses (x)-(z) above), each Credit Party shall defend, protect, indemnify, pay
and save harmless each Indemnified Party from (A) any Claims which may be imposed on, incurred by, or asserted against any Indemnified Party arising out of or in any way relating to or as a consequence, direct or indirect, of the issuance of

any Hazardous Substances affecting the Real Property (whether or not the same originates or emerges from the Real Property or any contiguous real estate), including any Claims consisting of or relating to the imposition or assertion of any Lien on
any of the Real Property under any Environmental Laws and any loss of value of the Real Property as a result of the foregoing except to the extent such loss, liability, damage and expense is attributable to any Hazardous Discharge resulting from
actions on the part of Agent or any Lender. The Credit Parties’ obligations under this Section 16.5 shall arise upon the discovery of the presence of any Hazardous Substances in reportable quantities at the Real Property, whether or not
any federal, state, or local environmental agency has taken or threatened any action in connection with the presence of any Hazardous Substances, in each such case except to the extent that any of the foregoing arises out of the gross negligence or
willful misconduct of the Indemnified Party (as determined by a court of competent jurisdiction in a final and non-appealable judgment). Without limiting the generality of the foregoing (but subject to clauses (x)-(z) above), this indemnity
shall extend to any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever (including reasonable fees and disbursements of counsel) asserted against or
incurred by any of the Indemnified Parties by any Person under any Environmental Laws or similar laws by reason of any Borrower’s or any other Person’s failure to comply with laws applicable to solid or hazardous waste materials, including
Hazardous Substances and Hazardous Waste, or other Toxic Substances. No Indemnified Person shall be liable for any damage arising from the use by others of information relating to the Credit Parties obtained through electronic, telecommunications or
other information systems, except to the extent such damages are found by a final, non-appealable judgment of a court to arise from the gross negligence or willful misconduct of such Indemnified Person. This Section 16.5 shall not apply to
Taxes. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, THIS INDEMNITY SHALL EXTEND TO ANY LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER
(INCLUDING FEES AND DISBURSEMENTS OF COUNSEL) ASSERTED AGAINST OR INCURRED BY ANY OF THE INDEMNIFIED PARTIES BY ANY PERSON UNDER ANY ENVIRONMENTAL LAWS OR SIMILAR LAWS BY REASON OF ANY BORROWER’S OR ANY OTHER PERSON’S FAILURE TO COMPLY

LENDERS, BUT INCLUDING ANY INTANGIBLES TAXES, STAMP TAX, RECORDING TAX OR FRANCHISE TAX) SHALL BE PAYABLE BY AGENT, LENDERS OR BORROWERS ON ACCOUNT OF THE EXECUTION OR DELIVERY OF THIS AGREEMENT, OR THE EXECUTION, DELIVERY, ISSUANCE OR RECORDING OF
ANY OF THE OTHER DOCUMENTS, OR THE CREATION OR REPAYMENT OF ANY OF THE OBLIGATIONS HEREUNDER, BY REASON OF ANY APPLICABLE LAW NOW OR HEREAFTER IN EFFECT, BORROWERS WILL PAY (OR WILL PROMPTLY REIMBURSE AGENT AND LENDERS FOR PAYMENT OF) ALL SUCH

 16.7. Survival. The obligations of Borrowers under Sections 2.2(g), 2.2(h), 3.7, 3.8, 3.9,
3.10, 16.5 and 16.9 and the obligations of Lenders under Sections 2.2, 2.15(b), 2.16, 2.18, 2.19, 14.8 and 16.5 , shall survive termination of this Agreement and the Other Documents and payment in full of the Obligations. 

16.8. Severability. If any part of this Agreement is contrary to, prohibited by, or deemed invalid under Applicable Laws, such
provision shall be inapplicable and deemed omitted to the extent so contrary, prohibited or invalid, but the remainder hereof shall not be invalidated thereby and shall be given effect so far as possible. 

16.9. Expenses. All documented out-of-pocket costs and expenses including attorneys’ fees (which in the case of clauses
(b) and (e) shall be reasonable and which in each case below, includes including the costs and disbursements of one (1) lead counsel for Agent and Lenders and one (1) additional local counsel in each applicable jurisdiction)
incurred by Agent on its behalf or on behalf of Lenders (a) in all efforts made to enforce payment of any Obligation or effect collection of any Collateral or enforcement of this Agreement or any of the Other Documents, (b) in connection
with the entering into, syndication, modification, amendment and administration of this Agreement or any of the Other Documents or any consents or waivers hereunder or thereunder and all related agreements, documents and instruments, (c) in

Other Document, whether through judicial proceedings or otherwise, (d) in defending or prosecuting any actions or proceedings arising out of or relating to Agent’s or any Lender’s transactions with any Credit Party or any other
creditor of a Credit Party, (e) in connection with any advice given to Agent or any Lender with respect to its rights and obligations under this Agreement and the Other Documents, may be charged to Borrowers’ Accounts or Sand Tiger’s
Accounts, as applicable and shall be part of the Obligations or (f) without limiting the foregoing, in ensuring compliance with Article IV and Section 6.6. 

16.10. Injunctive Relief. Each Borrower recognizes that, in the event any Borrower fails to perform, observe or discharge any of its
obligations or liabilities under this Agreement, or threatens to fail to perform, observe or discharge such obligations or liabilities, any remedy at law may prove to be inadequate relief to Lenders; therefore, Agent, if Agent so requests, shall be
entitled to temporary and permanent injunctive relief in any such case without the necessity of proving that actual damages are not an adequate remedy. 

16.11. Consequential Damages. Neither Agent nor any Lender, nor any agent or attorney for any of them, shall be liable to any Credit

result of any transaction contemplated under this Agreement or any Other Document.

provisions of this Agreement shall supersede such agreements. 
 16.16. Publicity. Each Borrower and each Lender hereby authorizes
Agent to make appropriate announcements of the financial arrangement entered into among Borrowers, Agent and Lenders, including announcements which are commonly known as tombstones, in such publications and to such selected parties as Agent shall in

Lender, provide all documentation and other information that Agent or such Lender reasonably requests in order to comply with its ongoing obligations under applicable “know your customer” and anti-money-laundering rules and regulations,
including the PATRIOT Act.

 145 

[Mammoth] Credit Agreement 

 16.19. Concerning Joint and Several Liability of Borrowers. 

(a) Each of Borrowers (other than Sand Tiger) is accepting joint and several liability hereunder in consideration of the financial
accommodations to be provided by Lenders under this Agreement, for the mutual benefit, directly and indirectly, of each of Borrowers and in consideration of the undertakings of each of Borrowers (other than Sand Tiger) to accept joint and several
liability for the obligations of each of them; provided, however, Sand Tiger shall only be liable for the Sand Tiger Obligations. 

(b) Each of Borrowers jointly and severally hereby irrevocably and unconditionally accepts, not merely as a surety but also as a co-debtor and
primary obligor, joint and several liability with the other Borrowers with respect to the payment and performance of all of the Obligations, it being the intention of the parties hereto that all the Obligations shall be the joint and several
obligations of each of Borrowers without preferences or distinction among them; provided, however, Sand Tiger shall only be liable for the Sand Tiger Obligations. 

(c) If and to the extent that any of the Borrowers shall fail to make any payment with respect to any of the Obligations as and when due or to
perform any of the Obligations in accordance with the terms thereof, then in each such event, the other Borrowers will make such payment with respect to, or perform, such Obligation; provided, however, that Sand Tiger’s liability
shall be limited to Sand Tiger’s Obligations. 
 (d) The obligations of each Borrower under the provisions of this Section 16.19
constitute full recourse obligations of such Borrower, enforceable against it to the full extent of its properties and assets, irrespective of the validity, regularity or enforceability of this Agreement or any other circumstances whatsoever. 

(e) Except as otherwise expressly provided herein, each Borrower hereby waives notice of acceptance of its joint and several liability, notice
of any Advance made under this Agreement, notice of occurrence of any Event of Default, or of any demand for any payment under this Agreement (except as otherwise provided herein), notice of any action at any time taken or omitted by any Lender
under or in respect of any of the Obligations, any requirement of diligence and, generally, all demands, notices and other formalities of every kind in connection with this Agreement. Each Borrower hereby assents to, and waives notice of, any
extension or postponement of the time for the payment of any of the Obligations, the acceptance of any partial payment thereon, any waiver, consent or other action or acquiescence by any Lender at any time or times in respect of any default by any
Borrower in the performance or satisfaction of any term, covenant, condition or provision of this Agreement, any and all other indulgences whatsoever by any Lender in respect of any of the Obligations, and the taking, addition, substitution or
release, in whole or in part, at any time or times, of any security for any of the Obligations or in part, at any time or times, of any security for any of the Obligations or the addition, substitution or release, in whole or in part, of any
Borrower. Without limiting the generality of the foregoing, each Borrower assents to any other action or delay in acting or failure to act on the part of any Lender, including, without limitation, any failure strictly or diligently to assert any
right or to pursue any remedy or to comply fully with the applicable laws or regulations thereunder which might, but for the provisions of this Section 16.19, afford grounds for terminating, discharging or relieving such Borrower, in whole or
in part, from any of its obligations under this Section 16.19, it being the intention of each Borrower that, so long as any of the Obligations remain unsatisfied, the obligations of such Borrower under this Section 16.19 shall not be
discharged except by 

  
 146 

[Mammoth] Credit Agreement 

 
performance and then only to the extent of such performance or except as otherwise agreed in writing in accordance with Section 16.2. The Obligations of each Borrower under this
Section 16.19 shall not be diminished or rendered unenforceable by any winding up, reorganization, arrangement, liquidation, reconstruction or similar proceeding with respect to any Borrower or any Lender. The joint and several liability of
Borrowers hereunder shall continue in full force and effect notwithstanding any absorption, merger, amalgamation or any other change whatsoever in the name, membership, constitution or place of formation of any Borrower or any Lender. 

(f) The provisions of this Section 16.19 are made for the benefit of the Lenders and their respective successors and assigns, and may be
enforced by any such Person from time to time against any of the Borrowers as often as occasion therefor may arise and without requirement on the part of any Lender first to marshal any of its claims or to exercise any of its rights against any of
the other Borrowers or to exhaust any remedies available to it against any of the other Borrowers or to resort to any other source or means of obtaining payment of any of the Obligations or to elect any other remedy. The provisions of this
Section 16.19 shall remain in effect until all the Obligations shall have been paid in full or otherwise fully satisfied. If at any time, any payment, or any part thereof, made in respect of any of the Obligations, is rescinded or must
otherwise be restored or returned by any Lender upon the insolvency, bankruptcy or reorganization of any of the Borrowers, or otherwise, the provisions of this Section 16.19 will forthwith be reinstated in effect, as though such payment had not
been made. 
 (g) Notwithstanding any provision to the contrary contained herein or in any other of the Other Documents, to the extent the
joint obligations of a Borrower shall be adjudicated to be invalid or unenforceable for any reason (including, without limitation, because of any applicable state or federal law relating to fraudulent conveyances or transfers) then the obligations
of each Borrower hereunder shall be limited to the maximum amount that is permissible under Applicable Law (whether federal or state and including, without limitation, any federal or state bankruptcy laws). 

(h) Borrowers hereby agree, as among themselves, that if any Borrower shall become an Excess Funding Borrower (as defined below), each other
Borrower shall, on demand of such Excess Funding Borrower (but subject to the next sentence hereof and to subsection (B) below), pay to such Excess Funding Borrower an amount equal to such Borrower’s Pro Rata Share (as defined below and
determined, for this purpose, without reference to the properties, assets, liabilities and debts of such Excess Funding Borrower) of such Excess Payment (as defined below). The payment obligation of any Borrower to any Excess Funding Borrower under
this Section 16.19(h) shall be subordinate and subject in right of payment to the prior payment in full of the Obligations of such Borrower under the other provisions of this Agreement, and such Excess Funding Borrower shall not exercise any
right or remedy with respect to such excess until payment and satisfaction in full of all of such Obligations. For purposes hereof, (i) “Excess Funding Borrower” shall mean, in respect of any Obligations arising under the other
provisions of this Agreement (hereafter, the “Joint Obligations”), a Borrower that has paid an amount in excess of its Pro Rata Share of the Joint Obligations; (ii) “Excess Payment” shall mean, in respect of any Joint
Obligations, the amount paid by an Excess Funding Borrower in excess of its Pro Rata Share of such Joint Obligations; and (iii) “Pro Rata Share”, for the purposes of this Section 16.19(h), shall mean, for any Borrower, the ratio
(expressed as a percentage) of (A) the amount by which the 

  
 147 

[Mammoth] Credit Agreement 

 
aggregate present fair salable value of all of its assets and properties exceeds the amount of all debts and liabilities of such Borrower (including contingent, subordinated, unmatured, and

pursuant to the Proceeds of Crime Money Laundering and Terrorist Financing Act (Canada) and other applicable anti-money laundering, anti-terrorist financing, government sanction and “know your client” laws, under the laws of Canada
(collectively, including any guidelines or orders thereunder, “AML Legislation”), Agent and Lenders may be required to obtain, verify and record information regarding each Borrower, its respective directors, authorized signing
officers, direct or indirect shareholders or other Persons in control of such Borrower, and the transactions contemplated hereby. Borrowing Agent shall promptly provide all such information, including supporting documentation and other evidence, as
may be reasonably requested by any Lender or Agent, or any prospective assign or participant of a Lender or Agent, necessary in order to comply with any applicable AML Legislation, whether now or hereafter in existence. 

If Agent has ascertained the identity of any Borrower or any authorized signatories of any Borrower for the purposes of applicable AML

signatory in doing so. 

16.22. Acknowledgment and

ownership in such EEA Financial Institution, its parent entity, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with
respect to any such liability under this Agreement or any Other Document; or (iii) the variation of the terms of such liability in connection with the exercise of the Write-Down and Conversion powers of any EEA Resolution Authority.

[        ] [    ], 20[    ], that to the best of my knowledge in my capacity as Chief Financial Officer and not in my individual capacity: 

I am the duly elected, qualified and acting Authorized Officer of the Borrowers. Each Borrower is a limited partnership, corporation, or limited liability
company duly formed, existing, and in good standing under the laws of the State of Delaware. 
 I am familiar with all of the business and financial
affairs of each Borrower, including, without limiting the generality of the foregoing, all of the matters hereinafter described.

 [MAMMOTH]
FORM OF FINANCIAL CONDITION CERTIFICATE 

 
as agent for itself and the other Lenders (PNC, together with its successors and assigns in such capacity, “Agent”), pursuant to the terms of that certain Revolving Credit and
Security Agreement, dated as of November 25, 2014, by and among each Borrower, Agent and Lenders party thereto (as amended, amended and restated, modified, supplemented, extended, joined and/or restated from time to time, the “Credit
Agreement”), for the purpose of inducing Agent and Lenders, now and from time to time hereafter, to advance monies and extend credit and other financial accommodations to the Borrowers pursuant to the Credit Agreement and the Other
Documents (as defined in the Credit Agreement) now and from time to time hereafter executed by the Borrowers and delivered to Agent and Lenders (all hereinafter collectively referred to as the “Loan Documents”). I understand that
you are relying on this Financial Condition Certificate. All capitalized terms used and not otherwise defined herein shall have the meanings ascribed to them in the Credit Agreement. 

I have reviewed the following and am fully familiar with the process pursuant to which they were generated: 

Pro Forma Balance Sheet of Mammoth and its subsidiaries, reflecting the consummation of the Transactions, attached hereto as Exhibit A (the
“Balance Sheet”). 
 The cash flow projections of Mammoth and its subsidiaries for the five year period following the Closing Date
(on a monthly basis for the first twelve months) and their projected balance sheets as of the Closing Date, attached hereto as Exhibit B (“Cash Flow Projections”). 

The Balance Sheet fairly reflects the combined financial condition of Mammoth and its subsidiaries as of the Closing Date after giving
effect to the Transactions, and has been prepared in accordance with GAAP, consistently applied, except as otherwise indicated therein and subject to normal year end audit adjustments and the absence of footnotes and other presentation items. The
Cash Flow Projections are based upon good faith estimates and stated assumptions believed to be reasonable and fair the date hereof made in light of conditions and facts now known and, as of the date hereof, reflect good faith, reasonable and fair
estimates of the information projected for the periods set forth therein; it being understood that (i) actual results may vary from such projections and that such variances may be material and (ii) no representation is made with respect to
information of an industry specific or general economic nature. 
 Taking into account rights of contribution and subrogation under Applicable Laws,
(x) each Credit Party is, and after giving effect to the Transactions, each Borrower will be solvent, able to pay its debts as they mature, has, and after giving effect to the Transactions, will have capital sufficient to carry on its business
and all businesses in which it is about to engage and (y) the fair present saleable value of its assets, calculated on a going concern basis, is in excess of the amount of its liabilities and will continue to be in excess of the amount of its
liabilities. All material undisputed debts owing to third parties by any Borrower are current and not past due. 

  
 [MAMMOTH]
FORM OF FINANCIAL CONDITION CERTIFICATE 

 The Credit Agreement and the Other Documents were and will be executed and delivered by Borrowers (to the
extent such Borrower is a party to such Other Documents) to Agent and Lenders in good faith and in exchange for reasonably equivalent value and fair consideration. 

I have reviewed the relevant terms of the Credit Agreement and any Other Document executed as of the date hereof by any Borrower and have made or have
caused to be made under my supervision a review of the transactions and conditions of the Borrowers from the beginning of the accounting period covered by the documents set forth in Paragraph 4 hereof to the date of this Certificate and that
such review has not disclosed the existence during such period of any condition or event which constitutes or would constitute a Default or Event of Default.

 IN WITNESS WHEREOF, each of the undersigned has executed this Certificate as of the date first
