(d) Upon receipt of an Incremental Borrowing Request Notice described in Section 2.02(b), the Administrative Agent

(e) Not later than (i) in the case of the Borrowing of New Loans, 12:00 noon (Central time) on the Effective Date, each Lender shall make
available a Loan in the amount of its New Commitment, or (ii) in the case of a Borrowing of Incremental Loans, 12:00 noon (Central time) on the date of such Borrowing, each Lender shall make available the amount of its requested Incremental

 Section 2.04. Interest Rates; Payments. 

(a) The principal amount of the Loans outstanding from day to day shall bear interest (computed on the basis of actual days elapsed in a 365
or 366 day year, as applicable) at a rate per annum equal to the lesser of (x) the sum of (i) LIBO Rate plus (ii) 8.5% (the sum of clauses (i) and (ii), the “Required Cash Interest”) plus (iii)
1.0% (such 1.0%, the “PIK Interest”) and (y) the Highest Lawful Rate, in either case, payable in arrears on each Quarterly Payment Date and on the Maturity Date, of which rate for all such dates other than the Maturity
Date all but the PIK Interest shall be paid in cash (with the remaining PIK Interest paid in kind). All PIK Interest will be capitalized by increasing the outstanding principal amount of the Loans on the relevant Quarterly Payment Date by the amount
of PIK Interest payable on such date (including, with respect to the first Quarterly Payment Date after the Effective Date, accrued and unpaid PIK Interest on the Existing Loans outstanding under the Existing Credit Agreement on the Effective Date).
The Borrower shall pay to the Administrative Agent for the accounts of each respective Lender all Required Cash Interest due on a Quarterly Payment Date on such date (including, with respect to the first Quarterly Payment Date after the Effective
Date, accrued and unpaid interest on the Existing Loans outstanding under the Existing Credit Agreement on the Effective Date). Unless the context otherwise requires, for all purposes hereof, references to the “outstanding principal
amount” or the “principal amount outstanding” of the Loans includes any PIK Interest so capitalized and added to the principal amount of the Loans from the date on which such interest has been so added. Notwithstanding the foregoing
provisions of this subsection, however, without the consent of the Required Lenders, during the continuance of an Event of Default all interest must be paid in cash. 

(b) If, on the first anniversary of the Effective Date, the 4 MM Condition is satisfied, then the Required Cash Interest payable at the
Quarterly Payment Date for the next full quarterly interest period after such date and at all times thereafter will be reduced by 1.0%. 

(c) If, at any time on or after the first anniversary of the Effective Date, (i) the Consolidated Leverage Ratio is less than 2.00:1.00
for the Reference Period ending as of the last day of the most recent fiscal year of the Borrower and (ii) the 4 MM Condition is satisfied, then the Required Cash Interest payable at the Quarterly Payment Date for the next full quarterly
interest period after such date and at all times thereafter will be reduced by 0.5%. For the avoidance of doubt, the reduction in Required Cash Interest set forth in Section 2.04(b) and this
Section 2.04(c) are additive, meaning that if the conditions in both Section 2.04(b) and this Section 2.04(c) are satisfied, the Required Cash Interest payable would be
reduced by an aggregate of 1.5% on the Quarterly Payment Date for the next full quarterly interest period after such date and at all times thereafter. 

(d) Notwithstanding anything to the contrary set forth in Section 2.04(a), upon the occurrence and during the
continuance of an Event of Default, the Indebtedness (whether or not accelerated) shall bear interest (including post-petition interest in any proceeding under Debtor Relief Laws, whether or not allowed in such a proceeding), at a rate per annum
equal to 

  
 35 

 
the lesser of (i) the sum of (A) the rate provided for in Section 2.04(a) plus (B) 2.0% per annum and (ii) the Highest Lawful Rate. Interest payable as
provided in this Section shall be payable in cash from time to time on demand. Payment or acceptance of the increased rates of interest provided for in this Section is not a permitted alternative to timely payment and shall not constitute a waiver
of any Event of Default or otherwise prejudice or limit any rights or remedies of the Administrative Agent or any Lender. 
 (e)
Notwithstanding the foregoing, if at any time the rate of interest calculated hereunder (as used in this sub-section, the “contract rate”) is limited to the Highest Lawful Rate, any subsequent
reductions in the contract rate shall not reduce the rate of interest on the Loans below the Highest Lawful Rate until the total amount of interest accrued equals the amount of interest which would have accrued if the contract rate had at all times
been in effect. In the event that at maturity (stated or by acceleration), or at final payment of any Loan, the total amount of interest paid or accrued on such Loan is less than the amount of interest which would have accrued if the contract rate
had at all times been in effect with respect thereto, then at such time, to the extent permitted by Law, the Borrower shall pay to the holder of such Loan an amount equal to the difference between (i) the lesser of the amount of interest which
would have accrued if the contract rate had at all times been in effect and the amount of interest which would have accrued if the Highest Lawful Rate had at all times been in effect, and (ii) the amount of interest actually paid on such Loan.

 Section 2.05. Mandatory Termination of Commitments; Maturity. 

(a) The New Commitment of each Lender shall terminate immediately after the funding of its New Loan on the Effective Date. The Incremental
Commitment of each Lender shall terminate on the Incremental Commitment Expiration Date; provided that, on the date of each Borrowing of Incremental Loans, the portion of the Incremental Commitments being funded pursuant to such Borrowing
shall terminate immediately after the funding of such Incremental Loans. 
 (b) The outstanding principal balance of the Loans, all accrued
but unpaid interest thereon, and all other Indebtedness shall be due and payable in full on the Maturity Date.

by the Borrower hereunder not later than 12:00 p.m. (Eastern time) on the date when due, in funds immediately available to the Administrative Agent at its address set forth herein. Administrative Agent will promptly (and if such payment is received
by Administrative Agent by 12:00 p.m. (Eastern time), and otherwise if reasonably possible, on the same Business Day) distribute to each Lender its proportionate share or, in the case of any fee, other appropriate share of each such payment received
by Administrative Agent for the account of Lenders. Whenever any payment of principal of, or interest on, any Loans shall be due on a day which is not a Business Day, the date for payment thereof shall be extended to the next succeeding Business
Day. If the date for any payment of principal is extended by operation of Law or otherwise, interest thereon shall be payable for such extended time. All amounts payable by the Borrower under the Loan Documents (whether principal, interest, fees,
expenses, or otherwise) shall be paid in full, without set-off or counterclaim. Amounts repaid on account of the Loans may not be reborrowed. 

  
 36 

 (b) Prior to the occurrence of an Event of Default, all principal payments received by Lenders
with respect to the Loans shall be applied to the Loans of each Lender ratably in accordance with the amounts thereof. 
 (c) After the
occurrence of an Event of Default, all amounts collected or received by Administrative Agent or any Lender from any Loan Party or in respect of any of the assets of any Loan Party shall be applied in the following order: 

(i) first, to the payment of all fees, indemnities, expenses and other amounts payable to the Administrative Agent
(including fees, expenses, and disbursements of counsel to the Administrative Agent) and all amounts due the Administrative Agent under Section 12.03; 

(ii) second, to the payment of all fees, indemnities, expenses and other amounts (other than principal and interest)
payable to Lenders (including fees, expenses, and disbursements of counsel to Lenders) ratably among them in proportion to the respective amounts described in this clause second payable to them; 

(iii) third, to the reimbursement of any advances made by Lenders to effect performance of any unperformed covenants of
any Loan Party under any of the Loan Documents; 
 (iv) fourth, to (A) accrued and unpaid interest on the Loans
and (B) unpaid principal of the Loans, ratably among the Lenders in proportion to the respective amounts described in this clause fourth payable to them; and 

(v) last, the balance, if any, after all of the Indebtedness has been indefeasibly paid in full, to the Borrower or as
otherwise required by Law. 
 Section 2.07. Fees. The Borrower shall pay to the Administrative Agent for its own account
(a) on the Effective Date, (i) a structuring fee of $1,700,000, (ii) an amendment fee of $925,000 and (iii) an arranger fee of $425,000, (b) in the event that Borrower fails to borrow the entire amount of the Incremental Loans

Agreement (commencing with March 1, 2018), an annual administration fee of $50,000. 
 Section 2.08. OID. The Borrower and
the Lenders intend that (i) the Loan is debt for federal income Tax purposes, (ii) the Loan issued to the Lenders constitute a single debt instrument for purposes of Sections 1271 through 1275 of the Internal Revenue Code and the Treasury
Regulations thereunder (pursuant to Treasury Regulations Section 1.1275-2(c)), (iii) such debt instrument shall be treated as issued with original issue discount (“OID”), (iv) to
the 

  
 37 

 
extent permissible and in accordance with applicable law, such debt instrument shall be treated as described in Treasury Regulations Section 1.1272-1(c) and therefore treated as governed by

Regulations Section 1.1275-4, (v) any calculation by the Borrower regarding the amount of OID for any accrual period on the Loan shall be subject to the review and comment of the Administrative Agent, and

accordance with the preceding clause (v)). The inclusion of this Section 2.08 is not an admission by any Lender that it is subject to United States taxation. 

ARTICLE III

 Section 3.01. Repayment of Indebtedness. 

(a) On each Quarterly Payment Date, commencing with the Quarterly Payment Date on June 1, 2018 and ending on the last Quarterly Payment

 Section 3.02. Mandatory Prepayments. 

(a) Unless the Administrative Agent shall otherwise agree, if (i) any Debt (excluding any Debt permitted pursuant to
Section 9.03) shall be incurred by the Borrower or any Subsidiary, or (ii) any Asset Sale shall occur, then within five (5) Business Days after the date of such incurrence or Asset Sale, the Borrower shall prepay
the principal amount of the Loans in an amount equal to the amount of the Net Cash Proceeds of such incurrence or Asset Sale; provided, however, that, upon written notice by the Borrower to the Administrative Agent not less than five
(5) Business Days after the date of receipt of any Net Cash Proceeds, such proceeds may be retained by the Borrower and its Subsidiaries (and be excluded from the prepayment requirements of this clause) if (w) the Borrower informs the
Administrative Agent in such notice of its good faith intention to apply (or cause one or more of its Subsidiaries to apply) such Net Cash Proceeds to the acquisition of other Property or, in the case of Net Cash Proceeds as a result of a Recovery
Event, to use such Net Cash Proceeds to repair the affected assets of Borrower or any Subsidiary, (x) within 180 days following the receipt of such Net Cash Proceeds, such proceeds are either applied to such acquisition or repair or the
Borrower or a Loan Party has entered into a bona fide binding contract not prohibited by this Agreement committing to make the acquisition or repair with a Person other than a Loan Party or any Affiliate of a Loan Party and such Net Cash Proceeds
are subsequently applied in accordance with such contract within ninety (90) days after the date such agreement is entered into, (y) if such proceeds are not applied to such acquisition or repair in accordance with the foregoing, the
Borrower shall prepay the principal amount of the Loans in an amount equal to the amount of such proceeds not so applied and (z) in the case of Net Cash Proceeds received as a result of an Asset Sale, such proceeds being applied or committed to
an acquisition do not exceed $5,000,000 during any period of twelve (12) consecutive calendar months. The provisions of this Section 3.02(a) do not constitute a consent to the incurrence of any Debt or any Asset Sale
not otherwise permitted by the terms hereof. 
 (b) Unless the Administrative Agent shall otherwise agree, if on any date any Loan Party
shall receive a Purchase Price Refund which yields aggregate proceeds to any Loan Party or any of its Subsidiaries in excess of $3,000,000, then, not less than five (5) Business Days after the date of receipt by such Person of such Purchase
Price Refund, the Borrower shall prepay the principal amount of the Loans in an amount equal to the amount of such Purchase Price Refund. The provisions of this Section 3.02 do not constitute a consent to the consummation
of any disposition of Property or series of related dispositions of Property not permitted by the terms of this Agreement. 
 (c) Upon the
occurrence of a Change in Control, the Borrower shall immediately prepay the outstanding principal amount of the Loans. 
 (d) Each
prepayment of the Loans pursuant to this Section 3.02 shall be applied in accordance with Section 2.06 and shall be accompanied by payment of accrued interest to the Prepayment Date on the
principal amount prepaid. 
 Section 3.03. Voluntary Prepayments. 

(a) The Borrower may, subject to Section 3.03(b) and the other provisions of this Agreement, upon not less than
fifteen (15) Business Days’ advance notice to the Administrative Agent (who shall promptly notify each Lender), prepay the principal of the Loans in whole or in part. Any partial prepayment shall be in a minimum amount of $1,000,000 and
shall be in an integral multiple of $500,000. 

  
 39 

 (b) Subject to prior notice in accordance with Section 3.03(a), the
Borrower may prepay the Loans at any time, and any prepayment made pursuant to Section 3.03(a) shall be made together with the Applicable Premium; provided, however, that, for the avoidance of doubt, the continuation of the
Existing Loans as Loans hereunder as of the Effective Date shall not constitute a prepayment of the Existing Loans. 
 (c) Each repayment
pursuant to this Section 3.03 shall be made, together with accrued interest to the date of payment, as set forth in Section 2.06. 

ARTICLE IV 
 PAYMENTS;
PRO RATA TREATMENT; SHARING OF SET-OFFS 
 Section 4.01. Payments Generally; Pro Rata
Treatment; Sharing of Set-offs. 
 (a) Payments by the Borrower. The Borrower shall make
each payment required to be made by it hereunder (whether of principal, interest, fees, or of amounts payable under Section 5.01, Section 5.02 or otherwise) prior to 12:00 p.m., Central time, on
the date when due, in immediately available funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully earned and shall not be refundable under any circumstances.
Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to
the Administrative Agent at its offices specified in Section 12.01, except that payments pursuant to Section 5.01, Section 5.02 and Section 12.03
shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment
hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such
extension. All payments hereunder shall be made in dollars. 
 (b) Application of Insufficient Payments. If at any time insufficient
funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably
among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the
amount of principal then due to such parties. 
 (c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of, or interest on, any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its
Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at 

  
 40 

 
face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate
amount of principal of and accrued interest on their respective Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be
rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this Section 4.01(c) shall not be construed to apply to any payment made by the Borrower pursuant
to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any
Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply). The 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 the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a
direct creditor of the Borrower in the amount of such participation. 
 Section 4.02. Presumption of Payment by the Borrower.
Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders that the Borrower will not make such payment, the Administrative
Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders, as the case may be, the amount due. In such event, if the Borrower has not in fact
made such payment, then each of the Lenders, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such
amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the rate then applicable to the Loans, determined as if any PIK Interest were payable in cash. 

Section 4.03. Disposition of Proceeds. The Mortgages contain an assignment by the Loan Parties that are party thereto unto and in
favor of the Administrative Agent, for the benefit of the Secured Parties, of all of such Loan Parties’ interest in and to production and all proceeds attributable thereto which may be produced from or allocated to the Mortgaged Property. The
Security Instruments further provide in general for the application of such proceeds to the satisfaction of the Indebtedness and other obligations described therein and secured thereby. Notwithstanding the assignment contained in such Security
Instruments, until the occurrence of an Event of Default, (a) the Administrative Agent and the Lenders agree that they will neither notify the purchaser or purchasers of such production nor take any other action to cause such proceeds to be
remitted to the Administrative Agent or the Lenders, but the Administrative Agent and the Lenders will instead permit such proceeds to be paid to the applicable Loan Parties and the Lessor and (b) the Lenders hereby authorize the Administrative
Agent to take such actions as may be necessary to cause such proceeds to be paid to the applicable Loan Parties and the Lessor.

 ARTICLE V 

INCREASED COSTS; TAXES; ILLEGALITY 

Section 5.01. Increased Costs. 

(a) Changes in Law. If any Change in Law shall: 

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or
for the account of, or credit extended by, any Lender; or 
 (ii) impose on any Lender any other condition affecting this
Agreement or Loans made by such Lender; 
 and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any
Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise), then the Borrower will pay to such Lender such additional
amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered. 
 (b) Capital
Requirements. If any Lender determines that any Change in Law regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding
company, if any, as a consequence of this Agreement or the Loans made by such Lender to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such
Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy or liquidity), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such
Lender or such Lender’s holding company for any such reduction suffered. 
 (c) Certificates. As promptly as practical, after a
Lender obtains knowledge of the facts that entitle it to compensation under this Section 5.01, but in any event within ninety (90) days after such Lender acquires such knowledge, such Lender shall provide Borrower with
a certificate which identifies the factual basis for its claim, the amount or amounts that such Lender has reasonably determined will compensate hereunder, and the manner in which such amount or amounts have been calculated. Any Lender claiming
additional compensation under this Section 5.01 shall use reasonable efforts (consistent with legal and regulatory restrictions) to reduce or eliminate any such additional compensation which may thereafter accrue and which
efforts would not, in the sole discretion of such Lender, be otherwise. A certificate setting forth the basis for determining such amounts necessary to compensate such Lender (including the calculations used to arrive at such additional amounts and
the assumptions on which such calculations were based), submitted to the Borrower by the Administrative Agent, shall be conclusive evidence, absent manifest error, of the correctness of such amount. The Borrower shall pay such Lender the amount
shown as due on any such certificate within 20 Business Days after receipt thereof. 
 (d) Effect of Failure or Delay in Requesting
Compensation. Failure or delay on the part of any Lender to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s right to demand such compensation; provided that
the Borrower shall not be required to compensate a Lender pursuant to this Section 5.01 for any increased costs or reductions incurred more than 180 days prior to the date that such Lender notifies the Borrower of the
Change in Law giving rise to such increased costs or reductions and 

  
 42 

 
of such Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof. 

Section 5.02. Taxes. 

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower or any Guarantor under any Loan
Document shall be made free and clear of and without deduction or withholding for any Taxes, including any Indemnified Taxes or Other Taxes; provided that if the Borrower or any Guarantor shall be required under applicable law to deduct any
Taxes from such payments, then (i) if such Taxes are an Indemnified Tax or Other Taxes, the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable
under this Section 5.02(a)), the Administrative Agent or Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower or such Guarantor
shall make such deductions and (iii) the Borrower or such Guarantor shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. 

(b) Payment of Other Taxes by the Borrower. The Borrower shall timely pay any Other Taxes to the relevant Governmental Authority in
accordance with applicable law. 
 (c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent and
each Lender within 10 Business Days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes payable or paid by the Administrative Agent, or such Lender, as the case may be, on or with respect to any payment by or
on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 5.02) and any penalties, 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 Authority. A certificate of the Administrative Agent or a
Lender as to the amount of such payment or liability under this Section 5.02 shall be delivered to the Borrower and shall be conclusive absent manifest error; provided that the Borrower shall not have any obligation
to indemnify the Administrative Agent or such Lender for any amounts paid by the Administrative Agent or such Lender under this Section 5.02 more than two years prior to the date the Administrative Agent or such Lender
notifies the Borrower of the amount of such payment. 
 (d) Indemnification by the Lenders. Each Lender shall severally indemnify the
Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and
without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 12.04(c) relating to the maintenance of a Participant Register
and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or
not such Taxes were correctly or legally 

  
 43 

 
imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive
absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any
other source against any amount due to the Administrative Agent under this paragraph (d). 
 (e) Evidence of Payments. As soon as
practicable after any payment of Taxes by the Borrower or a Guarantor to a Governmental Authority pursuant to this Section 5.02, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 

(f) Status of Lenders. 

(i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any
Loan Document shall deliver to the Withholding Agent, at the time or times reasonably requested by the Withholding Agent, such properly completed and executed documentation reasonably requested by the Withholding Agent as will permit such payments
to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Withholding Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the
Withholding Agent as will enable the Withholding Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the
completion, execution and submission of such documentation (other than such documentation set forth in Section 5.02(f)(ii)(A) and (ii)(B) and Section 5.02(g) below) shall not be required if
in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. 

(ii) Without limiting the generality of the foregoing, in the event that the Borrower is a “United States person” as
defined in Section 7701(a)(30) of the Code, 
 (A) any Lender that is a “United States person” as defined in
Section 7701(a)(3) of the Code shall deliver to the Withholding Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Withholding Agent),
executed originals of IRS Form W-9 certifying that such Lender is exempt from United States federal backup withholding Tax; 

  
 44 

 (B) any Foreign Lender shall, to the extent it is legally entitled to do so,
deliver to the Withholding Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable
request of the Withholding Agent), whichever of the following is applicable: 
 (1) in the case of a Foreign Lender claiming
the benefits of an income Tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of the applicable IRS Form W-8 establishing
an exemption from, or reduction of, United States federal withholding Tax pursuant to the “interest” article of such Tax treaty and (y) with respect to any other applicable payments under any Loan Document, the applicable IRS Form W-8 establishing an exemption from, or reduction of, United States federal withholding Tax pursuant to the “business profits” or “other income” article of such Tax treaty; 

(2) executed originals of IRS Form W-8ECI; 

(3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of
the Code, (x) a certificate substantially in the form of Exhibit F-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a
“10 percent equityholder” of the Borrower within the meaning of Section 871(h)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (together with any certificate
substantially in the form of Exhibit F-2, F-3, or F-4, a “U.S. Tax Compliance
Certificate”) and (y) executed originals of IRS Form W-8BEN-E; or 

(4) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form
W-8IMY, accompanied by the applicable IRS Form W-8 or IRS Form W-9, and/or other certification documents from each beneficial
owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance
Certificate substantially in the form of Exhibit F-4 on behalf of each such direct and indirect partner; and 

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Withholding Agent (in such number
of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Withholding Agent), executed originals
of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in United States federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to
permit the Withholding Agent to determine the withholding or deduction required to be made. 

  
 45 

 Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or
inaccurate in any respect, it shall update such form or certification or promptly notify the Withholding Agent in writing of its legal inability to do so. 

(g) FATCA. If a payment made to a Lender under this Agreement would be subject to United States Federal withholding Tax imposed by
FATCA if such Lender 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 Lender shall deliver to the Withholding Agent, at the time or
times prescribed by law and at such time or times reasonably requested by the Withholding Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation
reasonably requested by the Withholding Agent as may be necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that such Lender has complied with such Lender’s obligations under FATCA and to determine the
amount to deduct and withhold from such payment. Solely for purposes of this Section 5.02(g), “FATCA” shall include any amendments made to FATCA after the date of this Agreement. 

(h) Survival. Each party’s obligations under this Section 5.02 shall survive the resignation or
replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document. 

Section 5.03. Mitigation Obligations. Each Lender may make any Loans to the Borrower through any Lending Office, provided
that the exercise of this option shall not affect the obligation of the Borrower to repay Loans in accordance with the terms of this Agreement. If any Lender requests compensation under Section 5.01, or if the Borrower
is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.02, then such Lender shall use reasonable efforts to designate a different Lending
Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the reasonable judgment of such Lender, such designation or assignment (i) would
eliminate or reduce amounts payable pursuant to Section 5.01 or Section 5.02, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and
would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. 

Section 5.04. Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any
Lender or its applicable Lending Office to honor its obligation to make or maintain Loans, then such Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Loans shall be
suspended (the “Affected Loans”) until such time as such Lender may again make and maintain such Loans.

Loan Party is a party has been duly executed and delivered by such Loan Party and constitutes a legal, valid and binding obligation of such Loan Party, enforceable in accordance with its terms, subject to applicable Debtor Relief Laws and subject to
general principles of equity, regardless of whether considered in a proceeding in equity or at law. 
 Section 7.03. Approvals; No
Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority or any other third Person (including equityholders, members, partners or any class of
directors or managers, whether interested or disinterested, of the Borrower or any other Person), nor is any such consent, approval, registration, filing or other action necessary for the validity or enforceability of any Loan Document or the
consummation of the transactions contemplated thereby, except such as have been obtained or made and are in full force and effect other than (i) the recording and filing of the Security Instruments as required by this Agreement and

creation or imposition of any Lien on any material Property of any Loan Party (other than the Liens created by the Loan Documents).

Governmental Authority pending against or, to the knowledge of the Borrower, threatened against or affecting any Loan Party or the Lessor (i) not fully covered by insurance (except for normal deductibles) as to which there is a reasonable
possibility of an adverse determination that, if adversely determined, could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect, (ii) that involve any Loan Document or the Transactions or
(iii) that could impair the consummation of the Transactions. 
 (b) Since the date of this Agreement, there has been no change in the
status of the matters disclosed in Schedule 7.05 that, individually or in the aggregate, has resulted in a Material Adverse Effect.

Borrower, none of such Properties are adversely affected by any material Release or threatened Release of a Hazardous Material originating or emanating from any other real property;

operations and businesses of any of the Loan Parties’ Properties that could reasonably be expected to form the basis for a claim for damages or compensation; and

its Property and the conduct of its business. 
 (b) None of the Loan Parties is in default nor has any event or circumstance occurred

Section 7.09. Taxes. Each of the Loan Parties has timely filed or caused to be filed all Tax returns and reports required by
applicable law to have been filed, where such Tax returns accurately reflect in all material respects all liabilities for Taxes of the Loan Parties for the periods covered thereby, and has paid or caused to be paid all Taxes required to have been
paid by it, except Taxes that are being contested in good faith by appropriate proceedings and for which the Borrower or such other Loan Party, as applicable, has set aside on its books adequate reserves in accordance with GAAP. The charges,
accruals and reserves on the books of the Loan Parties in respect of Taxes and other governmental charges are, in the reasonable opinion of the Borrower, adequate. No Tax Lien has been filed and, to the knowledge of the Borrower, no claim is being
asserted with respect to any such Tax or other such governmental charge. 
 Section 7.10. ERISA. 

(a) Each Plan is in compliance in all respects with the applicable provisions of ERISA, the Code and other applicable laws, except for such
noncompliance as could not reasonably be expected, either individually or in the aggregate, to result in a Material Adverse Effect; and each Plan that is intended to be a qualified plan under Section 401(a) of the Code has received a favorable
determination letter from the IRS to the effect that the form of such Plan is qualified under Section 401(a) of the Code and the trust related thereto has been determined by the IRS to be exempt from Federal income tax under Section 501(a)
of the Code, or an application for such a letter is currently being processed by the IRS, and, to the knowledge of the Borrower, nothing has occurred that would prevent or cause the loss of such tax-qualified
status. 
 (b) Other than routine claims for benefits, there are no pending or, to the knowledge of the Borrower, threatened claims, actions
or lawsuits, or action by any Governmental Authority, with respect to any Plan that, either individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect. To the knowledge of the Borrower, there has been no
“prohibited transaction” (as defined in Section 406 of ERISA or Section 4975 of the Code) or violation of the fiduciary responsibility rules with respect to any Plan that, either individually or in the aggregate, has had or could
reasonably be expected to have a Material Adverse Effect. 

  
 55 

 (c) Except as could not reasonably be expected, either individually or in the aggregate, to have
a Material Adverse Effect, no ERISA Event has occurred, and none of the Borrower, any Loan Party, nor any ERISA Affiliate is aware of any fact, event or circumstance that, either individually or in the aggregate, could reasonably be expected to
constitute or result in an ERISA Event with respect to any Pension Plan or Multiemployer Plan. 
 (d) Except as could not reasonably be
expected, either individually or in the aggregate, to have a Material Adverse Effect, full payment when due has been made of all amounts which the Borrower, each other Loan Party or any ERISA Affiliate is required, under the terms of each Plan,
Pension Plan, Multiemployer Plan or applicable law, to have paid as contributions to such Plan, Pension Plan or Multiemployer Plan as of the date hereof. 

(e) None of the Loan Parties nor any ERISA Affiliate sponsors, maintains, or contributes to an employee welfare benefit plan, as defined in
Section 3(1) of ERISA, including, without limitation, any such plan maintained to provide benefits to former employees of such entities (other than in accordance with Section 4980B of the Code or any similar State law), that may not be
terminated by the Borrower, any other Loan Party or any ERISA Affiliate in its sole discretion at any time without any material liability. 

(f) The present value of all accrued benefit liabilities (as defined in Section 4001(a)(16) of ERISA) under each Pension Plan (based on
those assumptions used to fund such Pension Plan) did not, as of the last annual valuation date prior to the date on which this representation is made or deemed made, exceed the value of the assets of such Pension Plan allocable to such accrued
benefits by a material amount (any such excess, “Unfunded Pension Liabilities”). As of the most recent valuation date for each Multiemployer Plan, the potential liability of the Borrower, any Loan Party or any ERISA Affiliate
for a complete withdrawal from such Multiemployer Plan (within the meaning of Section 4203 of ERISA), when aggregated with such potential liability for a complete withdrawal from all Multiemployer Plans, is zero. 

Section 7.11. Disclosure; No Material Misstatements. The Borrower has disclosed to the Administrative Agent and the Lenders all
agreements, instruments and corporate or other restrictions to which any Loan Party is subject, and all other matters known to it, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. None of
the reports, financial statements, certificates or other information furnished by or on behalf of the Loan Parties to the Administrative Agent or any Lender or any of their Affiliates in connection with the negotiation of this Agreement or any other
Loan Document or delivered hereunder or under any other Loan Document (as modified or supplemented by other information so furnished) contains any material misstatement of fact or omits to state any material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not misleading; provided that, with respect to projected financial information, the Borrower represents only that such information was prepared in good faith based upon
assumptions believed to be reasonable at the time. There is no fact peculiar to the Loan Parties which could reasonably be expected to have a Material Adverse Effect or in the future is reasonably likely to have a Material Adverse Effect and which
has not been set forth in 

  
 56 

 
this Agreement or the Loan Documents or the other documents, certificates and statements furnished to the Administrative Agent or the Lenders by or on behalf of the Loan Parties prior to, or on,
the date hereof in connection with the transactions contemplated hereby. There are no statements or conclusions in any Reserve Report which are based upon or include misleading information or fail to take into account material information regarding
the matters reported therein, it being understood that projections concerning volumes attributable to the Sand Properties of the Borrower and the other Loan Parties and production and cost estimates contained in each Reserve Report are necessarily
based upon professional opinions, estimates and projections and that the Borrower and the other Loan Parties do not warrant that such opinions, estimates and projections will ultimately prove to have been accurate. 

Section 7.12. Insurance. The Loan Parties have (a) all insurance policies sufficient for the compliance by each of them with
all material Governmental Requirements and all material agreements and (b) insurance coverage in at least amounts and against such risk (including, without limitation, public liability) that are usually insured against by companies similarly
situated and engaged in the same or a similar business for the assets and operations of the Loan Parties. The Administrative Agent and the Lenders have been named as additional insureds in respect of such liability insurance policies and the
Administrative Agent has been named as loss payee with respect to Property loss insurance. 
 Section 7.13. Restriction on
Liens. None of the Borrower and its Subsidiaries is a party to any material agreement or arrangement, or subject to any order, judgment, writ or decree, which either restricts or purports to restrict its ability to grant Liens to the
Administrative Agent and the Secured Parties on or in respect of its Properties to secure the Indebtedness, except for (a) restrictions in the Revolving Credit Agreement and the Intercreditor Agreement with respect to granting Liens of higher
or equal priority to the Liens securing the RCA Obligations and (b) with respect to the Logistics Subsidiary Guarantors, restrictions or conditions imposed by any agreement relating to secured Indebtedness permitted by
Section 9.03(c) if such restrictions or conditions apply only to the property or assets securing such Indebtedness. 

Section 7.14. Subsidiaries and Capitalization. 

(a) Except as set forth on Schedule 7.14(a) or as disclosed in writing to the Administrative Agent (which shall promptly furnish a copy
to the Lenders), which shall be a supplement to Schedule 7.14(a), the Borrower has no Subsidiaries and the Borrower has no Foreign Subsidiaries. 

(b) Schedule 7.14(b) lists the owners of all authorized and outstanding Equity Interests of each Loan Party, including options and
other equity equivalents of each Loan Party, together with the amount and percentage of such Equity Interests held by each such owner. All of the outstanding Equity Interests of each Loan Party are validly issued and free and clear of any and all
Liens (other than Liens in favor of Administrative Agent pursuant to the Instruments and Permitted Liens). 
 (c) Except as set forth on
Schedule 7.14(c), there (i) are no outstanding or (ii) any present plans to issue any shares of capital stock or other Equity Interests, securities, rights, warrants or options convertible or exchangeable into or exercisable for any
shares of capital 

  
 57 

 
stock or other Equity Interests, stock appreciation rights or phantom stock of any Loan Party; provided, however, nothing contained in this Section 7.14
shall restrict any Loan Party from granting equity options to its managers or directors in accordance with this Agreement or pursuant to Lender’s prior written consent. Except as set forth on Schedule 7.14(c), no Loan Party is under any
obligation, contingent or otherwise, to redeem or otherwise acquire any shares of its capital stock or other Equity Interests or any securities, rights or options to acquire such capital stock, Equity Interests, stock appreciation rights or phantom
stock. Except as contemplated by the Organizational Documents of the Loan Parties in effect as of the date hereof and the Loan Documents, there are no agreements between any Persons, equityholders, or managers or directors of any Loan Party with
respect to the voting or transfer of any Equity Interests of a Loan Party owned by such parties or with respect to any other aspect of their affairs concerning any Loan Party other than those set forth on Schedule 7.14(c), none of which
conflict with the primary rights granted to the Administrative Agent or any Lender in the Loan Documents or any related agreements executed simultaneously herewith. 

(d) Except as set forth on Schedule 7.14(d), there are no statutory or contractual shareholders’ preemptive rights with respect to
the Equity Interests of any Loan Party. No Loan Party has violated any applicable federal or state securities laws in connection with the offer, sale or issuance of any of its Equity Interests. Except as set forth on Schedule 7.14(d), there
are no agreements granting registration rights to any Person with respect to any Equity Interests of a Loan Party, none of which conflict with the primary rights granted to the Administrative Agent or any Lender in the Loan Documents or any related
agreements executed simultaneously herewith. 
 Section 7.15. Location of Business and Offices. The Borrower’s jurisdiction
of organization is Delaware; the name of the Borrower as listed in the public records of its jurisdiction of organization is VPROP Operating, LLC; and the organizational identification number of the Borrower in its jurisdiction of organization is

business and chief executive offices are located at the address specified in Section 12.01 (or as set forth in a notice delivered pursuant to Section 8.01(l) and

the location of its principal place of business and chief executive office is stated on Schedule 7.14 (or as set forth in a notice delivered pursuant to Section 8.01(l)). 

Section 7.16. Properties; Titles, Etc. 

(a) The Loan Parties have Marketable Title to the Sand Properties evaluated in the most recently delivered Reserve Report and each of the Loan
Parties has good title to all its material personal Properties, in each case, free and clear of all Liens except Liens permitted by Section 9.04. After giving full effect to the Excepted Liens, the Loan Party specified as
the owner owns the net interests in production attributable to the Sand Interests as reflected in the most recently delivered Reserve Report, and the ownership of such Properties shall not in any material respect obligate such Loan Party to bear the
costs and expenses relating to the maintenance, development and operations of each such Property in an amount in excess of the 

  
 58 

 
working interest of each Property set forth in the most recently delivered Reserve Report that is not offset by a corresponding proportionate increase in the Borrower’s or such other Loan
Party’s net revenue interest in such Property. 
 (b) All material leases and agreements necessary for the conduct of the business of
the Loan Parties are valid and subsisting, in full force and effect, and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such leases or
agreements. 
 (c) The rights and Properties presently owned, leased or licensed by each Loan Party including, without limitation, all
easements and rights of way, include all rights and Properties necessary to permit each Loan Party to conduct its business in all material respects in the same manner as its business has been conducted prior to the date hereof. 

(d) All of the Properties of the Loan Parties which are reasonably necessary for the operation of their businesses are in good working
condition and are maintained in accordance with prudent business standards. 
 (e) Each Loan Party owns, or is licensed to use, all
trademarks, trade names, copyrights, patents and other intellectual Property material to its business, and the use thereof by the Borrower and such other Loan Parties does not infringe upon the rights of any other Person, except for any such
infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. The Loan Parties either own or have valid licenses or other rights to use all databases, geological data, geophysical
data, engineering data, seismic data, maps, interpretations and other technical information used in their businesses as presently conducted, subject to the limitations contained in the agreements governing the use of the same, which limitations are
customary for companies engaged in the business of the exploration and production of Finished Sand Inventory and other minerals. 

Section 7.17. Maintenance of Properties. The Sand Properties of the Loan Parties have been maintained, operated and developed in a
good and workmanlike manner and in material conformity with all Governmental Requirements and in material conformity with the provisions of all leases, subleases or other contracts comprising a part of the Sand Interests and other contracts and
agreements forming a part of the Sand Properties of Vista Sand and the other Loan Parties. Specifically in connection with the foregoing, Vista Sand has complied in all material respects with the Sand Hill Lease, the Lonestar Prop 50 Lease, the

such time as the Administrative Agent shall have consented to such revised plan in the exercise of its reasonable discretion, which consent shall not be unreasonably withheld, delayed or conditioned. The Administrative Agent shall use reasonable
efforts to respond to any such request within ten (10) Business Days after submission by the Borrower. 
 Section 8.17. Non-voting Observer. The Administrative Agent may in its discretion from time to time designate an employee or advisor to act as its non-voting representative (the

Parties or any Indebtedness of such Loan Parties, (ii) no such Observer shall be entitled to vote on any matter presented to such Managing Bodies of such Loan Parties, (iii) each Observer shall agree to maintain the confidentiality of all
information so provided in accordance with the terms of Section 12.11, (iv) such Observer shall not constitute a member of the Managing Body, (v) the Observer shall not actively engage in discussions at the meetings of

Loan Party’s Managing Body or its counsel, (A) access to such information or attendance at such meeting will adversely affect the attorney-client privilege between any Loan Party and its counsel, (B) access to such information or
attendance at such meeting will result in disclosure of trade secrets or conflict with other business purposes, (C) the Administrative Agent or any Lender would have a material conflict of interest with respect to such information or

shall, give timely advance notice to such Observer of all meetings of its Managing Body or any committees thereof and all proposals to such body for action without a board meeting, and any materials withheld in accordance with the proviso above,
allow such Observer to attend such meetings and, subject to the limitations described above, provide such Observer with copies of all written materials distributed to such managing body in connection with such meetings or proposals for action
without a meeting. The Observer must disclose to such Loan Parties all employment, consulting, directorship, advisory, investment and other similar relationships he or she may have with the Administrative Agent, or any Lender. If the Loan Parties

the continued service of a person as the Observer, in which case, the Administrative Agent may designate another person as a replacement.

 ARTICLE XI 

THE ADMINISTRATIVE AGENT 

Section 11.01. Appointment and Authority. 

(a) Each of the Lenders hereby irrevocably appoints ARCC to act on its behalf as the Administrative Agent hereunder and under the other Loan
Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably
incidental thereto. The provisions of this Article XI are solely for the benefit of the Administrative Agent and the Lenders, and neither the Borrower nor any other Loan Party shall have rights as a third party beneficiary of any of such
provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied
(or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties. 

(b) The Administrative Agent shall also act as the “collateral agent” under the Loan Documents, and each of the Lenders
hereby irrevocably appoints and authorizes the Administrative Agent to act as the agent of such Lender for purposes of acquiring, holding and enforcing any and all Liens on Mortgaged Property granted by the Borrower, the Guarantors and the Lessor to
secure any of the Indebtedness, together with such powers and discretion as are reasonably incidental thereto. In this connection, the Administrative Agent, as “collateral agent” and any co-agents, sub-agents and attorneys-in-fact appointed by the Administrative Agent pursuant to Section 11.05 for purposes
of holding or enforcing any Lien on the Mortgaged Property (or any portion thereof) granted under the Security Instruments, or for exercising any rights and remedies thereunder at the direction of the Administrative Agent), shall be entitled to the
benefits of all provisions of this Article XI and Article XII (including Section 12.03(c)), as though such co-agents, sub-agents
and attorneys-in-fact were the “collateral agent” under the Loan Documents) as if set forth in full herein with respect thereto. 

Section 11.02. Rights as a Lender. The Person serving as the Administrative Agent hereunder shall have the same rights and powers
in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context
otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other
advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

 Section 11.03. Exculpatory Provisions. The Administrative Agent shall not have any duties or obligations except those
expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent: 

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing; 

  
 90 

 (b) shall not have any duty to take any discretionary action or exercise any discretionary
powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of
the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the
Administrative Agent to liability or that is contrary to any Loan Document or applicable law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law; and 

(c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for
the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity. 

(d) 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 such
other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 10.02 and
Section 12.02) or (ii) in the absence of its own gross negligence or willful misconduct, as determined by a court of competent jurisdiction by a final and nonappealable judgment. The Administrative Agent shall be
deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent by the Borrower or a Lender. 

(e) shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or
in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of
any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other
agreement, instrument or document, or the creation, perfection or priority of any Lien purported to be created by the Security Instruments, (v) the value or the sufficiency of any Mortgaged Property, or (v) the satisfaction of any
condition set forth in Article VI or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. 

Section 11.04. Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and
to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any
liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent may presume that such condition is
satisfactory to such Lender unless the Administrative Agent shall have received notice to the contrary from such Lender prior to the making of such Loan. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower),
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. 

  
 91 

 Section 11.05. Delegation of Duties. The Administrative Agent may perform any and all
of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such
sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of
the credit facilities provided for herein as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the
extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such
sub-agents. 
 Section 11.06. Resignation of Administrative Agent. 

(a) The Administrative Agent may at any time give notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice
of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If
no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation, (or such earlier day as shall be
agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may (but shall not be obligated to) on behalf of the Lenders, appoint a successor Administrative Agent meeting the
qualifications set forth above. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date. 

(b) With effect from the Resignation Effective Date (1) the retiring Administrative Agent shall be discharged from its duties and
obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lenders under any of the Loan Documents, the retiring Administrative Agent shall continue
to hold such collateral security until such time as a successor Administrative Agent is appointed) and (2) except for any indemnity payments or other amounts then owed to the retiring Administrative Agent, all payments, communications and
determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon
the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Administrative Agent (other than as provided
in Section 12.05 with respect to Section 5.02 and other than any rights to indemnity payments or other amounts owed to the retiring Administrative Agent as of the Resignation Effective Date), and
the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already 

  
 92 

 
discharged therefrom as provided above in this Section 11.06). The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to
its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article shall continue in effect for the
benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent
was acting as Administrative Agent. 
 Section 11.07. Non-Reliance on Administrative Agent,
Administrative Agent and Other Lenders. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made
its own credit analysis and decision to enter into this Agreement. Each such Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking any action under this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder. The
Administrative Agent shall not be required to keep itself informed as to the performance or observance by the Borrower or any of the other Loan Parties of this Agreement, the Loan Documents or any other document referred to or provided for herein or
to inspect the Properties or books of the Borrower or the other Loan Parties. Each party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein.

 Section 11.08. Administrative Agent May File Proofs of Claim; Credit Bidding. In case of the pendency of any proceeding under
any Debtor Relief Law or any other judicial proceeding relative to any Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and
irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise: 

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other
Indebtedness that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under Section 12.03) allowed in such judicial
proceeding; and 
 (b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the
same; 
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby
authorized by each Lender to make such payments to the Administrative Agent and, if the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable
compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 12.03. 

  
 93 

 Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or
consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Indebtedness or the rights of any Lender to authorize the Administrative Agent to vote in respect of the claim of
any Lender or in any such proceeding. 
 The Secured Parties hereby irrevocably authorize the Administrative Agent, at the direction of the
Required Lenders, to credit bid all or any portion of the Indebtedness (including accepting some or all of the Mortgaged Property in satisfaction of some or all of the Indebtedness pursuant to a deed in lieu of foreclosure or otherwise) and in such
manner purchase (either directly or through one or more acquisition vehicles) all or any portion of the Mortgaged Property (a) at any sale thereof conducted under the provisions of the Bankruptcy Code of the United States, including under
Sections 363, 1123 or 1129 of the Bankruptcy Code of the United States, or any similar laws in any other jurisdictions to which a Loan Party is subject, (b) at any other sale or foreclosure or acceptance of collateral in lieu of debt conducted
by (or with the consent or at the direction of) the Administrative Agent (whether by judicial action or otherwise) in accordance with any applicable law. In connection with any such credit bid and purchase, the Indebtedness owed to the Secured
Parties shall be entitled to be, and shall be, credit bid on a ratable basis (with Indebtedness with respect to contingent or unliquidated claims receiving contingent interests in the acquired assets on a ratable basis that would vest upon the
liquidation of such claims in an amount proportional to the liquidated portion of the contingent claim amount used in allocating the contingent interests) in the asset or assets so purchased (or in the Equity Interests or debt instruments of the
acquisition vehicle or vehicles that are used to consummate such purchase). In connection with any such bid (i) the Administrative Agent shall be authorized to form one or more acquisition vehicles to make a bid, (ii) to adopt documents
providing for the governance of the acquisition vehicle or vehicles (provided that any actions by the Administrative Agent with respect to such acquisition vehicle or vehicles, including any disposition of the assets or Equity Interests
thereof shall be governed, directly or indirectly, by the vote of the Required Lenders, irrespective of the termination of this Agreement and without giving effect to the limitations on actions by the Required Lenders contained in
Section 12.02(b), (iii) the Administrative Agent shall be authorized to assign the relevant Indebtedness to any such acquisition vehicle pro rata by the Lenders, as a result of which each of the Lenders shall be deemed to
have received a pro rata portion of any Equity Interests and/or debt instruments issued by such an acquisition vehicle on account of the assignment of the Indebtedness to be credit bid, all without the need for any Secured Party or acquisition
vehicle to take any further action, and (iv) to the extent that Indebtedness that is assigned to an acquisition vehicle is not used to acquire Mortgaged Property for any reason (as a result of another bid being higher or better, because the
amount of Indebtedness assigned to the acquisition vehicle exceeds the amount of debt credit bid by the acquisition vehicle or otherwise), such Indebtedness shall automatically be reassigned to the Lenders pro rata and the Equity Interests and/or
debt instruments issued by any acquisition vehicle on account of the Indebtedness that had been assigned to the acquisition vehicle shall automatically be cancelled, without the need for any Secured Party or any acquisition vehicle to take any
further action. 

  
 94 

 Section 11.09. Collateral and Guaranty Matters. Without limiting the provision of
Section 11.10, the Lenders irrevocably authorize the Administrative Agent, at its option and in its discretion: 

(a) to release any Lien on any Property granted to or held by the Administrative Agent under any Loan Document (i) upon termination of
the Commitments and payment in full of all Indebtedness, (ii) that is sold or otherwise disposed of or to be sold or otherwise disposed of as part of or in connection with any sale or other disposition permitted hereunder or under any other
Loan Document to a Person that is not the Borrower or a Guarantor, or (iii) if approved, authorized or ratified in writing in accordance with Section 12.02; and 

(b) to subordinate any Lien on any property granted to or held by the Administrative Agent under any Loan Document to the holder of any Lien
on such property that is permitted by Section 9.04(d). 
 Upon request by the Administrative Agent at any time,
the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its obligations under the Guaranty Agreement
pursuant to this Section 11.09. In each case as specified in this Section 11.09, the Administrative Agent will, at the Borrower’s expense, execute and deliver to the Borrower, Guarantors or
Lessor, as applicable, such documents as such Person may reasonably request to evidence the release of such item of Property or Mortgaged Property from the assignment and security interest granted under the Security Instruments or to subordinate its
interest in such item, or to release such Guarantor from its obligations under the Guaranty Agreement, in each case in accordance with the terms of the Loan Documents and this Section 11.09. 

The Administrative Agent shall not be responsible for or have a duty to ascertain or inquire into any representation or warranty regarding the
existence, value or collectability of the Mortgaged Property, the existence, priority or perfection of the Administrative Agent’s Lien thereon, or any certificate prepared by the Borrower, any Guarantor or the Lessor in connection therewith,
nor shall the Administrative Agent be responsible or liable to the Lenders for any failure to monitor or maintain any portion of the Mortgaged Property. 

Section 11.10. Action by Administrative Agent. The Administrative Agent shall have no duty to take any discretionary action or
exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise in writing as directed by the Required Lenders (or such
other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) and in all cases the Administrative Agent shall be fully justified in failing or refusing to take any
discretionary action or exercise any discretionary power hereunder or under any other Loan Documents unless it shall (a) receive written instructions from the Required Lenders or the Lenders, as applicable, (or such other number or percentage
of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) specifying the action to be taken and (b) be indemnified to its satisfaction by the Lenders against any and all
liability and expenses which may be incurred by it by reason of taking or continuing to take any 

  
 95 

 
such action. The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent shall be binding on all of the Lenders. If a Default has occurred
and is continuing, then the Administrative Agent shall take such action with respect to such Default as shall be directed by the Required Lenders, provided that, unless and until the Administrative Agent shall have received such directions,
the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall the
Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, the Loan Documents or applicable law. The Administrative Agent shall not be liable to any Lender
for any action taken or not taken by it with the consent or at the request of the Required Lenders or the Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in
Section 12.02), and otherwise the Administrative Agent shall not be liable for any action taken or not taken by it hereunder or under any other Loan Document or under any other document or instrument referred to or provided
for herein or therein or in connection herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE, except for its own gross negligence or willful misconduct.

 Section 12.02. Waivers; Amendments. 

(a) No failure on the part of the Administrative Agent, any other Agent or any Lender to exercise and no delay in exercising, and no course of
dealing with respect to, any right, power or privilege, or any abandonment or discontinuance of steps to enforce such right, power or privilege, under any of the Loan Documents shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege under any of the Loan Documents preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of the Administrative Agent, any other Agent and
the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any
departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by Section 12.02(b), and then such waiver or consent shall be effective only in the specific instance and for the
purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any other Agent, any Lender may have had notice or
knowledge of such Default at the time. 
 (b) Subject to the last sentence of the definition of “LIBO Rate”, neither this
Agreement nor any provision hereof nor any other Loan Document nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the
Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal
amount of any Loan or reduce the rate of interest thereon, or reduce any fees payable hereunder, or reduce any other Indebtedness hereunder or under any other Loan Document, without the written consent of each Lender affected thereby,
(iii) postpone the scheduled date of payment or prepayment of the principal amount of any Loan, or any interest thereon, or any fees payable hereunder, or any other Indebtedness hereunder or under any other Loan Document, or reduce the amount
of, waive or excuse any such payment, or postpone or extend the Maturity Date, without the written consent of each Lender affected thereby, (iv) change Section 4.01(b) or Section 4.01(c) in a
manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) waive or amend Article 6, Section 8.14 or Section 10.02(c) or
change the definition of the terms “Domestic Subsidiary,” “Foreign Subsidiary,” or “Subsidiary,” without the written consent of each Lender, (vi) waive or amend Section 11.10 without the
written consent of each Lender affected thereby, (vii) release any Guarantor (except as set forth in the Guaranty Agreement), 

  
 97 

 
release all or substantially all of the collateral, without the written consent of each Lender, or (viii) change any of the provisions of this Section 12.02(b) or
any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant any consent hereunder or any other Loan Documents,
without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or any other Agent hereunder or under any other Loan Document without
the prior written consent of the Administrative Agent or such other Agent, as the case may be. Notwithstanding the foregoing, any supplement to Schedule 7.14 (Loan Parties and Subsidiaries) shall be effective simply by delivering to the
Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders. 

Section 12.03. Expenses, Indemnity; Damage Waiver. 

(a) The Borrower shall pay (i) all reasonable and documented
out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including, without limitation, the reasonable and documented fees, charges and
disbursements of counsel and other outside consultants for the Administrative Agent, the reasonable and documented travel, photocopy, mailing, courier, telephone and other similar expenses, including all Syndtrak (or similar service) expenses, and
the reasonable and documented cost of environmental assessments and audits and surveys and appraisals, in connection with the syndication of the credit facilities provided for herein, the preparation, negotiation, execution, delivery and
administration (both before and after the execution hereof and including advice of counsel to the Administrative Agent as to the rights and duties of the Administrative Agent and the Lenders with respect thereto) of this Agreement, the Intercreditor
Agreement, the Subordination Agreement and the other Loan Documents and any amendments, modifications or waivers of or consents related to the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be
consummated), (ii) all reasonable and documented costs, expenses, Taxes, assessments and other charges incurred by the Administrative Agent or any Lender in connection with any filing, registration, recording or perfection of any security interest
contemplated by this Agreement or any Security Instrument or any other document referred to therein and (iii) if a Default has occurred, all documented
out-of-pocket expenses incurred by the Administrative Agent or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent or
any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement or any other Loan Document, including its rights under this Section 12.03, or in connection with the Loans made,
including, without limitation, all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans; provided that
all Lenders shall be represented by the same legal counsel (which may be a law firm engaged by the Lenders or attorneys employed by a Lender or a combination of the foregoing) selected by the Lenders; provided, that if such legal counsel
determines in good faith that representing all such Lenders would or could result in a conflict of interest under Laws or ethical principles applicable to such legal counsel or that a defense or counterclaim is available to a Lender that is not
available to all such Lenders, then to the extent reasonably necessary to avoid such a conflict of interest or to permit unqualified assertion of such a defense or counterclaim, each affected Lender shall be entitled to separate representation by
legal counsel selected by that Lender and reasonably acceptable to Borrower; and provided further that the Administrative Agent shall at all times be entitled to representation by separate legal counsel (which may be a law firm or attorneys
employed by the Administrative Agent or a combination of the foregoing). 

  
 98 

 (b) THE BORROWER SHALL INDEMNIFY THE ADMINISTRATIVE AGENT AND EACH LENDER, AND EACH RELATED PARTY
OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING CALLED AN “INDEMNITEE”) AGAINST, AND DEFEND AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, PENALTIES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE
REASONABLE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (i) THE EXECUTION OR DELIVERY OF THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY OR THEREBY, THE PERFORMANCE BY THE PARTIES HERETO OR THE PARTIES TO ANY OTHER LOAN DOCUMENT OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS
CONTEMPLATED HEREBY OR BY ANY OTHER LOAN DOCUMENT (PROVIDED THAT THE INDEMNIFICATION IN THIS CLAUSE (i) SHALL NOT EXTEND TO DISPUTES SOLELY BETWEEN OR AMONG THE ADMINISTRATIVE AGENT, THE LENDERS OR THEIR RESPECTIVE AFFILIATES), (ii) THE
FAILURE OF THE BORROWER OR ANY OTHER LOAN PARTY TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS AGREEMENT, OR WITH ANY GOVERNMENTAL REQUIREMENT, (iii) ANY INACCURACY OF ANY REPRESENTATION OR ANY BREACH OF ANY WARRANTY OR COVENANT
OF THE BORROWER OR ANY GUARANTOR SET FORTH IN ANY OF THE LOAN DOCUMENTS OR ANY INSTRUMENTS, DOCUMENTS OR CERTIFICATIONS DELIVERED IN CONNECTION THEREWITH, (iv) ANY LOAN OR THE USE OF THE PROCEEDS THEREFROM, (v) ANY OTHER ASPECT OF THE LOAN
DOCUMENTS, (vi) THE OPERATIONS OF THE BUSINESS OF THE BORROWER AND THE OTHER LOAN PARTIES BY THE BORROWER AND THE OTHER LOAN PARTIES, (vii) ANY ASSERTION THAT THE LENDERS WERE NOT ENTITLED TO RECEIVE THE PROCEEDS RECEIVED PURSUANT TO THE
SECURITY INSTRUMENTS, (viii) ANY ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY OTHER LOAN PARTY REGARDING ANY OF THEIR PROPERTIES OR OPERATIONS, INCLUDING, THE PRESENCE, GENERATION, STORAGE, RELEASE, THREATENED RELEASE, USE, TRANSPORT,
DISPOSAL, ARRANGEMENT FOR DISPOSAL OR TREATMENT OF HAZARDOUS MATERIALS ON OR AT ANY OF THEIR PROPERTIES OR AT ANY OTHER PROPERTY TO WHICH HAZARDOUS MATERIALS GENERATED BY THE BORROWER, ANY OTHER LOAN PARTY OR THEIR OPERATIONS WERE OR ARE SENT FOR
DISPOSAL, (ix) THE BREACH OR NON-COMPLIANCE BY THE BORROWER OR ANY OTHER LOAN PARTY WITH ANY ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY OTHER LOAN PARTY, (x) THE PAST OWNERSHIP BY THE
BORROWER OR ANY OTHER LOAN PARTY OF ANY OF THEIR PROPERTIES OR PAST ACTIVITY ON ANY OF THEIR PROPERTIES WHICH, THOUGH LAWFUL AND FULLY PERMISSIBLE AT THE TIME, COULD RESULT IN PRESENT LIABILITY, (xi) THE PRESENCE, USE, RELEASE, STORAGE,
TREATMENT, DISPOSAL, GENERATION, THREATENED RELEASE, TRANSPORT, ARRANGEMENT FOR TRANSPORT OR ARRANGEMENT FOR DISPOSAL OF HAZARDOUS MATERIALS ON OR AT ANY OF 

  
 99 

 
THE PROPERTIES OWNED OR OPERATED BY THE BORROWER OR ANY OTHER LOAN PARTY, OR ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY THE
BORROWER OR ANY OF THE OTHER LOAN PARTIES OR AT ANY OTHER PROPERTY TO WHICH HAZARDOUS MATERIALS GENERATED BY THE BORROWER, ANY OTHER LOAN PARTY OR THEIR OPERATIONS WERE OR ARE SENT FOR DISPOSAL, (xii) ANY ENVIRONMENTAL LIABILITY RELATED IN ANY
WAY TO THE BORROWER OR ANY OF THE OTHER LOAN PARTIES, OR (xiii) ANY OTHER ENVIRONMENTAL, HEALTH OR SAFETY CONDITION IN CONNECTION WITH THE LOAN DOCUMENTS, OR (xiv) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING
RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, AND SUCH INDEMNITY SHALL EXTEND TO EACH INDEMNITEE NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE
OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION INCLUDING, WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF THE
INDEMNITEES OR BY REASON OF STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNITEES; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES
OR RELATED EXPENSES (A) ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE OR (B) ARE IN RESPECT OF ANY PROPERTY FOR
ANY OCCURRENCE ARISING FROM THE ACTS OR OMISSIONS OF THE ADMINISTRATIVE AGENT OR ANY LENDER DURING THE PERIOD AFTER WHICH SUCH PERSON, ITS SUCCESSORS OR ASSIGNS HAVE OBTAINED TITLE AND POSSESSION OF SUCH PROPERTY BY FORECLOSURE OR DEED IN LIEU OF
FORECLOSURE; BUT EXCLUDING ANY OCCURRENCE REGARDING ANY VIOLATION OF ENVIRONMENTAL LAW FIRST OCCURRING BEFORE SUCH PERIOD AND ANY HAZARDOUS MATERIAL OR ENVIRONMENTAL CONDITION FIRST PRESENT ON THE PROPERTY BEFORE SUCH PERIOD. 

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent under
Section 12.03(a) or (b), each Lender severally agrees to pay to the Administrative Agent such Lender’s ratable share, based on the aggregate Commitments (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the
Administrative Agent in its capacity as such. 
 (d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby
waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other
Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or the use of the proceeds thereof. 

  
 100 

 (e) All amounts due under this Section 12.03 shall be payable not later
than 10 Business Days after written demand therefor accompanied by appropriate documentation thereof. 
 Section 12.04. Successors
and Assigns. 
 (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby, except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or
transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section 12.04. Nothing in
this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants (to the extent provided in
Section 12.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders and their respective successors and assigns permitted hereby) any legal or
equitable right, remedy or claim under or by reason of this Agreement. 
 (b) Subject to the conditions set forth in
Section 12.04(b)(i), any Lender may assign to one or more Persons all or a portion of its interests, rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing
to it), with notice to the Borrower (failure to provide or delay in providing such notice shall not invalidate such assignment). 

(i) Assignments shall be subject to the following additional conditions: 

(A) the Borrower shall have consented to such assignment, such consent not to be unreasonably withheld, conditioned or delayed;
provided that no such consent of the Borrower shall be required if (1) an Event of Default has occurred and is continuing or (2) such assignment is to an Eligible Assignee; 

(B) except in the case of (1) an assignment to an assignee that is a Lender immediately prior to giving effect to such
assignment or an Affiliate of a Lender or (2) an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment
(determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Borrower and the Administrative Agent otherwise consent,
provided that no such consent of the Borrower shall be required if the assignee is an Eligible Assignee or if an Event of Default has occurred and is continuing; 

  
 101 

 (C) each partial assignment shall be made as an assignment of a proportionate
part of all the assigning Lender’s rights and obligations under this Agreement; 
 (D) the parties to each assignment
shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; 

(E) the assignee, if it shall not already be a Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire; and 
 (F) in no event may any Lender assign all or a portion of its rights and obligations under this
Agreement to the Borrower, any Affiliate of the Borrower or a natural person. 
 (ii) Subject to
Section 12.04(b)(iii) and the acceptance and recording thereof, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the
interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released
from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to
be entitled to the benefits of Section 5.01, Section 5.02 and Section 12.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that
does not comply with this Section 12.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with
Section 12.04(c). 
 (iii) The Administrative Agent, acting solely for this purpose as an agent of
the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans owing
to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders may treat each
Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any
Lender, at any reasonable time and from time to time upon reasonable prior notice. In connection with any changes to the Register, if necessary, the Administrative Agent will reflect the revisions on Annex I and forward a copy of such revised
Annex I to the Borrower and each Lender. For the avoidance of doubt, the foregoing provisions are intended to comply with the registration requirements in United States Treasury Regulations
Section 5f.103-1(c), or any successor provisions thereof, so that any payments made on a Loan or Note are considered to be paid on a debt instrument issued in “registered form” pursuant to such
regulations, and all parties hereto shall construe the provisions of this Credit Agreement to ensure that the Loans or Notes will be considered to have been so issued. 

  
 102 

 (iv) Upon its receipt of a duly completed Assignment and Assumption executed by
an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire and applicable tax forms (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in
Section 12.04(b) and any written consent to such assignment required by Section 12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained
therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 12.04(b). 

(c) (1) Any Lender may, without the consent of the Borrower, sell participations to one or more banks or other Person (other than the
Borrower, any Affiliate of the Borrower or a natural person) (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans
owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations,
(C) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement, and (D) if the Participant or,
if the Participant is a partnership, one or more direct or indirect partners of such Participant are claiming the portfolio interest exemption, such Participant may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-2 or Exhibit F-3, as applicable. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the
sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver described in the proviso to Section 12.02 that affects such Participant. In addition such agreement must provide that the Participant be bound by the provisions of
Section 12.03. Subject to Section 12.04(c)(i), the Borrower agrees that each Participant shall be entitled to the benefits of Section 5.01, and
Section 5.02 (in each case, without duplication of any benefits afforded the Lender granting such participation) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to
Section 12.04(b). Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, 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 Loans or other obligations under the Loan 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 any Loan Document) to
any Person except to the 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 

  
 103 

 
notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a
Participant Register. For the avoidance of doubt, the foregoing provisions are intended to comply with the registration requirements in United States Treasury Regulations Section 5f.103-1(c), or any
successor provisions thereof, so that any payments made on a Participant’s interest are considered to be paid on a debt instrument issued in “registered form” pursuant to such regulations, and all parties hereto shall construe (and
shall cause any participants to construe) the provisions of this Credit Agreement to ensure that any participant’s interest will be considered to have been so issued. 

(i) A Participant shall not be entitled to receive any greater payment under Section 5.01 or
Section 5.02 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the
Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.02 unless the Borrower is notified of the participation sold to such
Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 5.02(f) as though it were a Lender. 

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure
obligations of such Lender, including, without limitation, any pledge or assignment to secure obligations to a Federal Reserve Bank or other central bank, and this Section 12.04 shall not apply to any such pledge or
assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

 (e) Notwithstanding any other provisions of this Section 12.04, no transfer or assignment of the interests or
obligations of any Lender or any grant of participations therein shall be permitted if such transfer, assignment or grant would require the Borrower and the Guarantors to file a registration statement with the SEC or to qualify the Loans under the
“Blue Sky” laws of any state. 
 Section 12.05. Survival; Revival; Reinstatement. 

(a) All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments
delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any
Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time
any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid and so long as the
Commitments have not expired or terminated. The provisions of Section 5.01 (subject to Section 5.01(d)), Section 5.02 (subject to the proviso in the last sentence of
Section 5.02(c)) and Section 12.03 (for a period of two years after the Maturity 

  
 104 

 
Date) and Article XI shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or
termination of the Commitments or the termination of this Agreement, any other Loan Document or any provision hereof or thereof; provided that any time limitation on the survival of any provision hereunder shall be tolled for any claims filed
prior to the expiration of such time limitation until two months after final, non-appealable adjudication of any such claim. 

(b) To the extent that any payments on the Indebtedness or proceeds of any collateral are subsequently invalidated, declared to be fraudulent
or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Indebtedness so satisfied shall be revived and
continue as if such payment or proceeds had not been received and the Administrative Agent’s and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and each Loan Document shall continue in full force
and effect. In such event, each Loan Document shall be automatically reinstated and the Borrower shall take such action as may be reasonably requested by the Administrative Agent and the Lenders to effect such reinstatement. 

Section 12.06. Counterparts; Integration; Effectiveness. 

(a) This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute
an original, but all of which when taken together shall constitute a single contract. 
 (b) This Agreement, the other Loan Documents and
any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof and thereof. 
 (c) THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES. 
 (d) Except as provided in Section 6.01, this Agreement shall become effective when it shall have
been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic transmission (e.g. .pdf) shall be effective as delivery of a
manually executed counterpart of this Agreement. 
 Section 12.07. Severability. Any provision of this Agreement or any other
Loan Document held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and
enforceability of the remaining provisions hereof or thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. 

  
 105 

 Section 12.08. Right of Setoff. If an Event of Default shall have occurred and be
continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final)
at any time held and other obligations (of whatsoever kind) at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower or any other Loan Party against any of and all the obligations of the Borrower or any other
Loan Party owed to such Lender now or hereafter existing under this Agreement or any other Loan Document, irrespective of whether or not such Lender shall have made any demand under this Agreement or any other Loan Document and although such
obligations may be unmatured. The rights of each Lender under this Section 12.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender or its Affiliates may have. 

Section 12.09. GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS. 

(a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

 (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS SHALL BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE
UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, IN EITHER CASE LOCATED IN NEW YORK COUNTY, NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PARTY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN
RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF
FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES NOT
PRECLUDE A PARTY FROM OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT OTHERWISE HAVING JURISDICTION. 
 (c) EACH PARTY IRREVOCABLY
CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT THE ADDRESS SPECIFIED IN
Section 12.01 OR SUCH OTHER ADDRESS AS IS SPECIFIED PURSUANT TO Section 12.01 (OR ITS ASSIGNMENT AND ASSUMPTION), SUCH SERVICE TO BECOME EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING. NOTHING
HEREIN SHALL AFFECT THE RIGHT OF A PARTY OR ANY HOLDER OF A LOAN TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANOTHER PARTY IN ANY OTHER JURISDICTION. 

  
 106 

 (d) EACH PARTY HEREBY (i) IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN; (ii) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY
HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (iii) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL
FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (iv) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT,
THE LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS Section 12.09. 

Section 12.10. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only,
are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement. 

Section 12.11. Confidentiality. Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the
Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, partners, funding sources, administrators, employees and agents, including accountants, legal counsel and other
advisors and sub-advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information
confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process; provided that, subject to the Borrower’s obligation to
reimburse expenses under Section 12.03, it shall use commercially reasonable efforts to seek to obtain confidential treatment of such Information; provided further, that it shall not be liable for failure to obtain
such confidential treatment, (d) to any other party to this Agreement or any other Loan Document, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to
this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section 12.11, to (i) any
assignee of or Participant or investor in, or any prospective assignee of or Participant or investor in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any Swap
Agreement relating to the Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this
Section 12.11 or (ii) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this Section 

  
 107 

 
12.11, “Information” means all information received from the Borrower or any other Loan Party relating to the Borrower or any other Loan Party and their businesses,
other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by the Borrower or any other Loan Party; provided that, in the case of information received from the
Borrower or any other Loan Party after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this
Section 12.11 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own
confidential information. Notwithstanding anything herein to the contrary, “Information” shall not include, and the Borrower, the other Loan Parties, the Administrative Agent, each Lender and the respective Affiliates of each of the
foregoing (and the respective partners, directors, officers, employees, agents, advisors and other representatives of the aforementioned Persons), and any other party, may disclose to any and all Persons, without limitation of any kind (a) any
information with respect to the United States federal and state income tax treatment of the transactions contemplated hereby and any facts that may be relevant to understanding the United States federal or state income tax treatment of such
transactions (“tax structure”), which facts shall not include for this purpose the names of the parties or any other person named herein, or information that would permit identification of the parties or such other persons,
or any pricing terms or other nonpublic business or financial information that is unrelated to such tax treatment or tax structure, and (b) all materials of any kind (including opinions or other tax analyses) that are provided to the Borrower,
the Administrative Agent or such Lender relating to such tax treatment or tax structure. 
 Section 12.12. Interest Rate
Limitation. It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it
(including the laws of the United States of America, the State of Texas or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding
anything to the contrary in any of the Loan Documents or any agreement entered into in connection with or as security for the Loans, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable
to any Lender that is contracted for, taken, reserved, charged or received by such Lender under any of the Loan Documents or agreements or otherwise in connection with the Loans shall under no circumstances exceed the maximum amount allowed by such
applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or
would thereby be paid in full, refunded by such Lender to the Borrower); and (ii) in the event that the maturity of the Loans is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement
or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and excess
interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the
Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the 

  
 108 

 
Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be
amortized, prorated, allocated and spread throughout the stated term of the Loans until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at
any time and from time to time (A) the amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 12.12 and (B) in respect
of any subsequent interest computation period the amount of interest otherwise payable to such Lender would be less than the amount of interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the amount of
interest payable to such Lender in respect of such subsequent interest computation period shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the
total amount of interest which would have been payable to such Lender if the total amount of interest had been computed without giving effect to this Section 12.12. To the extent that Chapter 303 of the Texas Finance Code
is relevant for the purpose of determining the Highest Lawful Rate applicable to a Lender, such Lender elects to determine the applicable rate ceiling under such Chapter by the weekly ceiling from time to time in effect. Chapter 346 of the Texas
Finance Code does not apply to the Borrower’s obligations hereunder. 
 Section 12.13. EXCULPATION PROVISIONS. EACH OF THE
PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ
THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS
EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR
ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.” 

Section 12.14. No Third Party Beneficiaries. This Agreement, the other Loan Documents, and the agreement of the Lenders to make
Loans are solely for the benefit of the Borrower, and no other Person (including, without limitation, any other Loan Party, any obligor, contractor, subcontractor, supplier or materialsman) shall have any rights, claims, remedies or privileges
hereunder or under any other Loan Document against the Administrative Agent or any Lender for any reason whatsoever. Except as specified in Section 11.10 and Section 12.03, there are no third party
beneficiaries. 

  
 109 

 Section 12.15. USA Patriot Act Notice. Each Lender hereby notifies the Borrower that
pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information
that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act. 

Section 12.16. No Advisory or Fiduciary Responsibility. In connection with all aspects of each transaction contemplated hereby
(including in connection with any amendment, waiver or other modification hereof or of any other Loan Document), the Borrower acknowledges and agrees, and acknowledges its Subsidiaries’ understanding, that: (a)(i) no fiduciary, advisory or
agency relationship between the Borrower and its Subsidiaries and the Administrative Agent or any Lender is intended to be or has been created in respect of the transactions contemplated hereby or by the other Loan Documents, irrespective of whether
the Administrative Agent or any Lender has advised or is advising the Borrower or any Subsidiary on other matters; (ii) the arranging and other services regarding this Agreement provided by the Administrative Agent and the Lenders are arm’s-length commercial transactions between the Borrower and its Subsidiaries, on the one hand, and the Administrative Agent and the Lenders, on the other hand; (iii) the Borrower has consulted its own
legal, accounting, regulatory and tax advisors to the extent that it has deemed appropriate; and (iv) the Borrower is capable of evaluating, and understands and accepts, the terms, risks and conditions of the transactions contemplated hereby
and by the other Loan Documents; and (b)(i) the Administrative Agent and the Lenders each is and has been acting solely as a principal and, except as expressly agreed in writing by the relevant parties, has not been, is not, and will not be acting
as an advisor, agent or fiduciary for the Borrower or any of its Subsidiaries, or any other Person; (ii) none of the Administrative Agent nor the Lenders has any obligation to the Borrower or any of its Subsidiaries with respect to the
transactions contemplated hereby except those obligations expressly set forth herein and in the other Loan Documents; and (iii) the Administrative Agent and the Lenders and their respective Affiliates may be engaged, for their own accounts or
the accounts of customers, in a broad range of transactions that involve interests that differ from those of the Borrower and its Subsidiaries, and none of the Administrative Agent nor the Lenders has any obligation to disclose any of such interests
to the Borrower or its Subsidiaries. To the fullest extent permitted by law, the Borrower hereby waives and releases any claims that it may have against the Administrative Agent and the Lenders with respect to any breach or alleged breach of agency
or fiduciary duty in connection with any aspect of any transaction contemplated hereby. 
 Section 12.17. Electronic Execution of
Assignments and Certain Other Documents. The words “execution,” “execute,” “signed,” “signature,” and words of like import in or related to any document to be signed in connection with this Agreement and
the transactions contemplated hereby (including without limitation Assignment and Assumptions, Borrowing Request Notices, amendments, waivers and consents) shall be deemed to include electronic signatures, the electronic matching of assignment terms
and contract formations on electronic platforms approved by the Administrative Agent, or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the
use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and
Records Act, or any 

  
 110 

 
other similar state laws based on the Uniform Electronic Transactions Act; provided that notwithstanding anything contained herein to the contrary the Administrative Agent is under no
obligation to agree to accept electronic signatures in any form or in any format unless expressly agreed to by the Administrative Agent pursuant to procedures approved by it. 

Section 12.18. Intercreditor Agreement. The Lenders acknowledge the obligations of the Loan Parties under the RCA Loan Documents,
which are secured by Liens on assets of the Loan Parties, and that the relative Lien priorities and other creditor rights of the secured parties thereunder and the Secured Parties are as set forth in the Intercreditor Agreement. Each Lender hereby
acknowledges that it has received a copy of the Intercreditor Agreement and hereby (a) irrevocably consents to the subordination and equalization, as applicable, of the Liens on the collateral on the terms set forth in the Intercreditor
Agreement, (b) agrees that such Lender will be bound by the provisions of each Intercreditor Agreement as if it were a signatory thereto and will take no actions contrary to the provisions of such Intercreditor Agreement and (c) agrees
that such Lender shall not have any right of action whatsoever against the Administrative Agent as a result of any action taken by the Administrative Agent pursuant to this Section or in accordance with the terms of the Intercreditor Agreement. Each
Lender hereby further irrevocably authorizes and directs the Administrative Agent (i) to take such actions as shall be required to release Liens on the Collateral in accordance with the terms of the Intercreditor Agreement and (ii) to
enter into such amendments, supplements or other modifications to the Intercreditor Agreement in connection with any extension, renewal, refinancing or replacement of any secured indebtedness as are reasonably acceptable to the Administrative Agent
to give effect thereto, in each case on behalf of such Lender and without any further consent, authorization or other action by such Lender. The Administrative Agent shall have the benefit of the provisions of Article XI with respect to all
actions taken by it pursuant to this Section or in accordance with the terms of the Intercreditor Agreement to the full extent thereof. 

Section 12.19. Effect of Amendment and Restatement. 

(a) The parties hereto agree that: 

(i) on the Effective Date, the Indebtedness (as defined herein) represents, among other things, the amendment, consolidation,
and modification of the “Indebtedness” (as defined in the Existing Credit Agreement), as assumed by the Borrower; 

(ii) Parent, the Borrower, the other Loan Parties, the Administrative Agent and the Lenders acknowledge that, effective as of
the Effective Date, all interest, fees, expenses and other “Indebtedness” (as defined in the Existing Credit Agreement) that remain unpaid and outstanding as of the Effective Date will be assumed by the Borrower and remain outstanding and
payable under this Agreement and the other Loan Documents. The Borrower acknowledges that all Indebtedness outstanding as of the Effective Date constitutes valid and binding obligations of the Borrower without offset, counterclaim, defense, or
recoupment of any kind, except as enforcement may be limited by equitable principles or by bankruptcy, insolvency, reorganization, moratorium, or similar laws relating to or limiting creditor’s rights generally; 

  
 111 

 (iii) on the Effective Date, the Existing Credit Agreement will be amended and
restated in its entirety by this Agreement and the Existing Credit Agreement will thereafter be of no further force and effect, but this Agreement does not, and is not in any way intended to, constitute a novation of the obligations and liabilities
existing under the Existing Credit Agreement or to evidence payment of all or any portion of such obligations and liabilities; and 

(iv) the terms and conditions of this Agreement and the Administrative Agent’s and the Lenders’ rights and remedies
under this Agreement and the other Loan Documents apply to all of the “Indebtedness” (as defined in the Existing Credit Agreement) incurred under the Existing Credit Agreement that is continued under this Agreement; 

(b) Each Loan Party hereby reaffirms the Liens granted pursuant to the Security Instruments to the Administrative Agent for the benefit of the
Secured Parties, which Liens will continue in full force and effect during the term of this Agreement and any renewals thereof and will continue to secure the Indebtedness. 

(c) On and after the Effective Date, (i) all references to the Existing Credit Agreement in the Loan Documents (other than this
Agreement) will be deemed to refer to the Existing Credit Agreement as amended and restated by this Agreement; (ii) all references to any section (or subsection) of the Existing Credit Agreement in any Loan Document (but not in this Agreement)
will be deemed amended, mutatis mutandis, to refer to the corresponding provisions of this Agreement; and (iii) except as the context otherwise requires, on or after the Effective Date all references in this Agreement to this Agreement
(including for purposes of indemnification and reimbursement of fees) will be deemed to be references to the Existing Credit Agreement as amended and restated by this Agreement. 

(d) The amendment and restatement effected by this Agreement is limited as written and is not a consent to any other amendment, restatement,
or waiver or other modification, whether or not similar, and, except as expressly provided in this Agreement or in any other Loan Document, all terms and conditions of the Loan Documents remain in full force and effect unless otherwise specifically
amended by this Agreement or by any other Loan Document. 
 Section 12.20. Cashless Settlement. 

(a) Notwithstanding anything to the contrary contained in this Agreement, any Lender may exchange, continue, or rollover all or a portion of
its Loans or Commitments in connection with any refinancing, extension, loan modification, or similar transaction permitted by this Agreement pursuant to a cashless settlement mechanism approved by the Borrower, Administrative Agent, and such
Lender.

Execution Version 

AMENDED AND RESTATED GUARANTY AGREEMENT 

THIS AMENDED AND RESTATED GUARANTY AGREEMENT (as it may be amended, restated, amended and restated, supplemented or modified from time
to time, this “Guaranty”) is dated as of November 9, 2017, by each of the undersigned identified on the signature pages hereto as guarantors (together with any other entity that may become a party hereto as provided
herein, each a “Guarantor”, and collectively, the “Guarantors”), in favor of ARES CAPITAL CORPORATION in its capacity as administrative agent (the “Administrative
Agent”), each of the other Secured Parties and each of their successors and assigns as permitted pursuant to the Credit Agreement (as defined below) (the Administrative Agent, the other Secured Parties, and their successors and assigns,
collectively, the “Beneficiaries”). 
 PRELIMINARY STATEMENTS 

A. Lonestar Prospects, Ltd., a Texas limited partnership doing business as Vista Sand (“Vista Sand”), the lenders
party thereto, and the Administrative Agent, entered into that certain Senior Secured Credit Agreement dated as of March 1, 2017 (as amended, restated, amended and restated, supplemented or otherwise modified from time to time prior to the date
hereof, the “Existing Credit Agreement”). In connection with the Existing Credit Agreement, certain of Vista Sand’s subsidiaries executed that certain Guaranty Agreement dated as of March 1, 2017 (as amended,
restated, amended and restated, supplemented or otherwise modified from time to time prior to the date hereof, the “Existing Guaranty Agreement”) to guarantee the payment of the Indebtedness under the Existing Credit
Agreement and the other Loan Documents (as defined in the Existing Credit Agreement). 
 B. On even date herewith, VPROP Operating, LLC, a
Delaware limited liability company (the “Borrower”), assumed the obligations of Vista Sand under the Existing Credit Agreement and executed an Amended and Restated Senior Secured Credit Agreement (as amended, restated, amended and
restated, replaced, supplemented or otherwise modified from time to time, the “Credit Agreement”) by and among the Borrower, the Administrative Agent, the Persons party thereto as “lenders” (the
“Lenders”) and the other parties thereto, pursuant to which the Lenders agreed to amend and restate the terms of the Existing Credit Agreement and make certain extensions of credit to the Borrower for the purposes set forth
therein. Capitalized terms used but not defined herein have the respective meanings given to them in the Credit Agreement. 
 C. The parties
hereto desire to amend and restate the Existing Guarantee Agreement on the terms set forth in this Agreement in order to guarantee the Indebtedness under the Credit Agreement and the other Loan Documents (as defined in the Credit Agreement), as
provided herein. 
 D. The Lenders have required, as a condition to extending credit under the Credit Agreement, that each Guarantor execute
and deliver this Guaranty to guarantee the payment of the Indebtedness. 
 E. Each Guarantor has determined that valuable benefits will be
derived by it as a result of the Credit Agreement and the extension of credit made (and to be made) by the Lenders thereunder. 
 F. Each
Guarantor has further determined that the benefits accruing to it from the Credit Agreement exceed such Guarantor’s anticipated liability under this Guaranty. 

 Accordingly, for valuable consideration, the receipt and sufficiency of which are hereby
acknowledged and confessed, each Guarantor hereby covenants and agrees as follows: 
 1. Each Guarantor hereby, jointly and severally,
absolutely, irrevocably and unconditionally guarantees the prompt, complete and full payment when due, no matter how such shall become due, of the Indebtedness. 

2. Each Guarantor covenants that, so long as any Lender has any Commitment under the Credit Agreement or any Indebtedness remains outstanding
under the Credit Agreement or any other Loan Document, it will fully comply with the conditions, covenants, and agreements set forth in the Credit Agreement which are applicable to such Guarantor or which restricts such Guarantor from taking, or
requires such Guarantor to take, certain actions. Notwithstanding any contrary provision in this Guaranty, each Guarantor’s maximum liability under this Guaranty is limited, to the extent, if any, required so that its liability is not subject
to avoidance under applicable Debtor Relief Laws. 
 3. If any Guarantor is or becomes liable for any Indebtedness owing by any Loan Party
to any Beneficiary by endorsement or otherwise than under this Guaranty, such liability shall not be in any manner impaired or affected hereby, and the rights of Beneficiaries hereunder shall be cumulative of any and all other rights that
Beneficiaries may ever have against Guarantor. The exercise by any Beneficiary of any right or remedy hereunder or under any other instrument, at law or in equity, shall not preclude the concurrent or subsequent exercise of any other right or
remedy. 
 4. All obligations of each Guarantor hereunder, shall be absolute, irrevocable, unconditional and continuing irrespective of, and
each Guarantor hereby knowingly waives any defense arising out of: 
 (a) any extension, renewal, settlement, compromise,
waiver or release in respect of any of the Indebtedness, by operation of law or otherwise, or any obligation of any other guarantor of any of the Indebtedness, or any default, failure or delay, willful or otherwise, in the payment or performance of
the Indebtedness; 
 (b) any lack of validity or enforceability relating to or against the Borrower, any other Loan Party or
any other guarantor of any of the Indebtedness, for any reason related to the Credit Agreement, any other Loan Document or any other agreement or instrument governing or evidencing any Indebtedness, or any Governmental Requirements purporting to
prohibit the payment by the Borrower, any other Loan Party or any other guarantor of the Indebtedness of the principal of or interest on the Indebtedness; 

(c) any modification or amendment of or supplement to the Credit Agreement or any other Loan Document; 

(d) any change in the time, manner or place of payment of, or in any other term of, all or any part of the Indebtedness, or any
other amendment or waiver of or any consent to any departure from the Credit Agreement, any other Loan Document or any other agreement or instrument governing or evidencing any Indebtedness, including any increase or decrease in the amount of the
Commitments or Loans or the rate of interest thereon; 
 (e) any release, nonperfection or invalidity of any direct or
indirect security for any obligation of any Loan Party under the Credit Agreement or any other Loan Document or any obligations of any other guarantor of any of the Indebtedness, any amendment or waiver of, or consent to departure from, any other
guaranty or support document, any exchange, release or non-perfection of any direct or indirect security for any obligation of any Loan Party under the Credit 

  
 2 

 
Agreement or any other Loan Document, for all or any of the Loan Documents or Indebtedness, or any action or failure to act, including choice of remedies, manner of sale or use of proceeds, by
the Administrative Agent, any Lender or any other Person with respect to any collateral securing all or any part of the Indebtedness; 

(f) any change in the corporate existence, structure or ownership of the Borrower, any other Loan Party or any other guarantor
of any of the Indebtedness, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Borrower, any other Loan Party or any other guarantor of the Indebtedness, or any of their assets or any resulting release or
discharge of any obligation of the Borrower, any other Loan Party or any other guarantor of any of the Indebtedness; 
 (g)
any present or future law, regulation, decree or order of any jurisdiction (whether of right or in fact) or of any Governmental Authority thereof or any other event purporting to reduce, amend, restructure or otherwise affect any term of any Loan
Document or Indebtedness; 
 (h) any other setoff, defense or counterclaim whatsoever (in any case, whether based on
contract, tort or any other theory) with respect to the Credit Agreement, any other Loan Document, any other agreement or instrument or the transactions contemplated thereby which might constitute a legal or equitable defense available to, or
discharge of, the Borrower or any Guarantor; or 
 (i) any other act or omission to act or delay of any kind by the Borrower,
any other Loan Party, any other guarantor of the Indebtedness, the Administrative Agent, any Lender or any other Person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable
discharge of any Guarantor’s obligations hereunder, including any failure by a Loan Party to execute this Guaranty. 
 5. In the event
of default by the Borrower or any other Loan Party in payment of the Indebtedness, or any part thereof, when such Indebtedness becomes due, either by its terms or as the result of the exercise of any power to accelerate, each Guarantor shall, on
demand, and without further notice of dishonor and without any notice having been given to such Guarantor previous to such demand of the acceptance by Beneficiaries of this Guaranty, and without any notice having been given to such Guarantor
previous to such demand of the creating or incurring of such Indebtedness, pay the amount due thereon to Beneficiaries at the Administrative Agent’s office as set forth in the Credit Agreement. It shall not be necessary for any Beneficiary, in
order to enforce such payment by any Guarantor, first, to institute suit or exhaust its remedies against the Borrower, any other Guarantor or others liable on such Indebtedness, to have the Borrower joined with any Guarantor in any suit brought
under this Guaranty or to enforce its rights against any security which shall ever have been given to secure such Indebtedness; provided, however, that in the event any Beneficiary elects to enforce and/or exercise any remedies it may
possess with respect to any security for the Indebtedness prior to demanding payment from any Guarantor, such Guarantor shall nevertheless be obligated hereunder for any and all sums still owing to Beneficiaries on the Indebtedness and not repaid or
recovered incident to the exercise of such remedies. 
 6. Notice to any Guarantor of the acceptance of this Guaranty and of the making,
renewing or assignment of the Indebtedness and each item thereof, are hereby expressly and knowingly waived by each Guarantor. 
 7. Each
payment on the Indebtedness shall be deemed to have been made by the Borrower unless express written notice is given to the Administrative Agent at the time of such payment that such payment is made by a Guarantor as specified in such notice. 

  
 3 

 8. If all or any part of the Indebtedness at any time is secured, each Guarantor agrees that the
Administrative Agent and/or Lenders may at any time and from time to time, in their discretion and with or without valuable consideration, allow substitution or withdrawal of collateral or other security and release collateral or other security or
compromise or settle any amount due or owing under the Credit Agreement, or amend or modify in whole or in part the Credit Agreement or any Loan Document executed in connection with same without impairing or diminishing the Indebtedness of each
Guarantor hereunder. Each Guarantor further agrees that if any Loan Party executes, in favor of any Beneficiary, any collateral agreement, mortgage or other security instrument, the exercise by such Beneficiary of any right or remedy thereby
conferred on such Beneficiary shall be wholly discretionary with such Beneficiary, and that the exercise or failure to exercise any such right or remedy shall in no way impair or diminish the obligation of each Guarantor hereunder. Each Guarantor
further agrees that the Administrative Agent and the other Beneficiaries shall not be liable for their failure to use diligence in the collection of the Indebtedness or in preserving the liability of any person liable for the Indebtedness, and each
Guarantor hereby waives presentment for payment and notice of nonpayment, dishonor or protest (including, notice of acceleration), and diligence in bringing suits against any Person liable on the Indebtedness, or any part thereof. 

9. Each Guarantor agrees that Beneficiaries, in their discretion, may (i) bring suit against all guarantors (including, without
limitation, each Guarantor hereunder) of the Indebtedness jointly and severally or against any one or more of them, (ii) compound or settle with any one or more of such guarantors for such consideration as Beneficiaries may deem proper, and
(iii) release one or more of such guarantors from liability hereunder, and that no such action shall impair the rights of Beneficiaries to collect the Indebtedness (or the unpaid balance thereof) from other such guarantors of the Indebtedness,
or any of them, not so sued, settled with or released. Each Guarantor agrees, however, that nothing contained in this paragraph, and no action by Beneficiaries permitted under this paragraph, shall in any way affect or impair the rights or
obligations of such guarantors among themselves. 
 10. The representations and warranties in the Credit Agreement, to the extent applicable
to such Guarantor, are incorporated herein by reference, the same as if stated verbatim herein as representations and warranties made by each Guarantor, and each Guarantor, jointly and severally, represents and warrants that each of such
representations and warranties are true and correct (which representations and warranties shall be deemed to have been renewed at the time of any Incremental Loan under the Credit Agreement) in all material respects, except that (x) to the
extent that such representations and warranties are expressly limited to an earlier date, such representations and warranties shall continue to be true and correct in all material respects as of such specified earlier date and (y) to the extent
that any such representation and warranty is qualified by materiality, such representation and warranty (as so qualified) shall continue to be true and correct in all respects. Each Guarantor further represents and warrants to each Beneficiary that
(i) such Guarantor is a corporation, limited liability company or limited partnership, as applicable, duly organized and validly existing under the laws of the jurisdiction of its incorporation or formation; (ii) such Guarantor possesses
all requisite authority and power to authorize, execute, deliver and comply with the terms of this Guaranty; (iii) this Guaranty has been duly authorized and approved by all necessary action on the part of such Guarantor and constitutes a
legal, valid and binding obligation of such Guarantor enforceable in accordance with its terms, except as (a) the enforcement thereof may be limited by applicable Debtor Relief Laws, and (b) the availability of remedies may be limited by
equitable principles of general applicability; (iv) the execution, delivery and compliance by such Guarantor with this Guaranty does not violate any agreement, instrument, Governmental Requirement, regulation or order applicable to such
Guarantor; (v) no approval or consent of any person or entity, including but not limited to any court or governmental authority, or any filing or registration of any kind is required for the authorization, execution, delivery or compliance by
such Guarantor with this Guaranty which has not been obtained; and (vi) such Guarantor has (a) executed and delivered this Guaranty without reliance on the Administrative Agent or any Lender or any information

  
 4 

 
received from the Administrative Agent or any Lender and based upon such documents and information it deems appropriate, made an independent investigation of the transactions contemplated hereby
and the Borrower, the Borrower’s business, assets, operations, prospects and condition, financial or otherwise, and any circumstances which may bear upon such transactions, the Borrower or the obligations and risks undertaken herein with
respect to the Indebtedness; (b) adequate means to obtain from the Borrower on a continuing basis information concerning the Borrower; (c) full and complete access to the Loan Documents and any other documents executed in connection with
the Loan Documents; and (d) not relied and will not rely upon any representations or warranties of the Administrative Agent or any Lender not embodied herein or any acts heretofore or hereafter taken by the Administrative Agent or any Lender
(including but not limited to any review by the Administrative Agent or any Lender of the affairs of the Borrower). 
 11. Each Guarantor
covenants and agrees that until the Indebtedness is paid and performed in full, except as otherwise provided in the Credit Agreement or unless Lenders give their prior written consent to any deviation therefrom, it will (i) at all times
maintain its existence and authority to transact business in any state or jurisdiction where such Guarantor has material assets and operations, (ii) promptly deliver to the Administrative Agent such information respecting its business affairs,
assets and liabilities as any Beneficiary may reasonably request, and (iii) duly and punctually observe and perform all covenants applicable to such Guarantor under the Credit Agreement and the other Loan Documents. 

12. This Guaranty is for the benefit of the Secured Parties, their successors and assigns, and in the event of an assignment by any Secured
Party (or its successors or assigns) of the Indebtedness, or any part thereof, in accordance with Section 12.04(b) of the Credit Agreement, the rights and benefits hereunder, to the extent applicable to the Indebtedness so
assigned, may be transferred with such Indebtedness. This Guaranty is binding upon each Guarantor and its successors and assigns except that no Guarantor may assign or otherwise transfer any of its obligations hereunder without the prior written
consent of each Secured Party. 
 13. No modification, consent, amendment or waiver of any provision of this Guaranty, nor consent to any
departure by any Guarantor therefrom, shall be effective unless the same shall be in writing and signed by the Administrative Agent with requisite Lender approval as required under the Credit Agreement, and then shall be effective only in the
specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall, of itself, entitle such Guarantor to any other or further notice or demand in similar or other circumstances. No delay or omission by
the Beneficiaries in exercising any power or right hereunder shall impair any such right or power or be construed as a waiver thereof or any acquiescence therein, nor shall any single or partial exercise of any such power preclude other or further
exercise thereof, or the exercise of any other right or power hereunder. All rights and remedies of the Beneficiaries hereunder are cumulative of each other and of every other right or remedy which the Beneficiaries may otherwise have at law or in
equity or under any other contract or document, and the exercise of one or more rights or remedies shall not prejudice or impair the concurrent or subsequent exercise of other rights or remedies. 

14. No provision herein or in any promissory note, instrument or any other Loan Document executed by the Borrower or any Guarantor evidencing
the Indebtedness shall require the payment or permit the collection of interest in excess of the Highest Lawful Rate. If any excess of interest in such respect is provided for herein or in any such promissory note, instrument, or any other Loan
Document, the provisions of this paragraph shall govern, and neither the Borrower nor any Guarantor shall be obligated to pay the amount of such interest to the extent that it is in excess of the Highest Lawful Rate. The intention of the parties
being to conform strictly to any applicable federal or state usury laws now in force, all promissory notes, instruments and other Loan Documents executed by the Borrower or any Guarantor evidencing the Indebtedness shall be held subject to reduction
to the amount allowed under said usury laws as now or hereafter construed by the courts having jurisdiction. 

  
 5 

 15. If any Guarantor should breach or fail to perform any provision of this Guaranty, each
Guarantor agrees to pay Beneficiaries all reasonable costs and expenses (including court costs and reasonable attorneys’ fees) incurred by Beneficiaries in the enforcement hereof and the collection of guaranteed amounts. 

16. (a) The liability of each Guarantor under this Guaranty shall in no manner be impaired, affected or released by the insolvency,
bankruptcy, making of an assignment for the benefit of creditors, arrangement, compensation, composition or readjustment of any Loan Party, or any proceeding affecting the status, existence or assets of any Loan Party or other similar proceedings
instituted by or against any Loan Party and affecting the assets of any other Loan Party. 
 (b) Each Guarantor acknowledges
and agrees that any interest on any portion of the Indebtedness which accrues after the commencement of any proceeding referred to in clause (a) above (or, if interest on any portion of the Indebtedness ceases to
accrue by operation of law by reason of the commencement of said proceeding, such interest as would have accrued on such portion of the Indebtedness if said proceedings had not been commenced) shall be included in the Indebtedness, and no Loan Party
shall be relieved of any portion of such Indebtedness on account of such proceeding. Each Guarantor will, to the extent not prohibited by law from doing so, permit any trustee in bankruptcy, receiver, debtor in possession, assignee for the benefit
of creditors or similar person to pay Beneficiaries or the Administrative Agent, or allow the claim of Beneficiaries or the Administrative Agent in respect of, any such interest accruing after the date on which such proceeding is commenced. 

(c) In the event that all or any portion of the Indebtedness is paid by any Loan Party, the obligations of each Guarantor
hereunder shall continue and remain in full force and effect or be reinstated, as the case may be, in the event that all or any part of such payment(s) are rescinded or recovered directly or indirectly from the Administrative Agent or any other
Beneficiary as a preference, fraudulent transfer or otherwise, and any such payments which are so rescinded or recovered shall constitute Indebtedness for all purposes under this Guaranty. 

17. Each Guarantor understands and agrees that any amounts of any Guarantor on account with any Secured Party may, if an Event of Default has
occurred and is continuing, be offset to satisfy the obligations of such Guarantor hereunder. 
 18. Each Guarantor hereby subordinates and
makes inferior any and all indebtedness now or at any time hereafter owed by any Loan Party to such Guarantor to the Indebtedness evidenced by the Credit Agreement and the other Loan Documents and agrees if an Event of Default shall have occurred
and be continuing, not to permit any Loan Party to repay, or to accept payment from any Loan Party of, such indebtedness or any part thereof without the prior written consent of Required Lenders. Each Guarantor further agrees that if the
Administrative Agent or any Beneficiary so requests, such indebtedness of the Borrower to such Guarantor shall be collected, enforced and received by such Guarantor as trustee for the Administrative Agent (for the benefit of the Secured Parties)
and, while an Event of Default is continuing, shall be paid over to the Administrative Agent (for the benefit of the Secured Parties) on account of the Indebtedness but without reducing or affecting in any manner the liability of such Guarantor
under the other provisions of this Guaranty. 

  
 6 

 19. Each Guarantor hereby agrees that, to the extent that any Guarantor shall have paid more than
its proportionate share (calculated on the basis of the maximum liability of a Guarantor as determined under Paragraph 2, relative to the maximum liability of all Guarantors, as so determined) of any payment made hereunder, such
Guarantor shall be entitled to seek and receive contribution from and against any other Guarantor hereunder which has not paid its proportionate share of such payment. Each Guarantor’s right of contribution shall be subject to the terms and
conditions of Paragraph 2, Paragraph 18 and Paragraph 20. The provisions of this Paragraph 19 shall in no respect limit the obligations and liabilities of any Guarantor to the Secured Parties,
and each Guarantor shall remain liable to the Secured Parties for the full amount guaranteed by such Guarantor hereunder. 
 20.
Notwithstanding any payment made by any Guarantor hereunder or any set-off or application of funds of any Guarantor by any Secured Party, no Guarantor shall be entitled to be subrogated to any of the rights of
any Secured Party against the Borrower or any Guarantor or any collateral security or guaranty or right of offset held by any Secured Party for the payment of the Indebtedness, nor shall any Guarantor seek or be entitled to seek any indemnity,
exoneration, participation, contribution or reimbursement from the Borrower or any Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Secured Parties by the Loan Parties on account of the Indebtedness
are paid in full and the Commitments are terminated. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Indebtedness shall not have been paid in full, such amount shall be held by such
Guarantor in trust for the Administrative Agent (for the benefit of the Secured Parties), segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Administrative Agent (for the benefit
of the Secured Parties) in the exact form received by such Guarantor (duly endorsed by such Guarantor to the Administrative Agent, if required), to be applied against the Indebtedness whether matured or unmatured. 

21. As of the date hereof, the fair saleable value of the Property of each Guarantor is greater than the total amount of liabilities
(including contingent and unliquidated liabilities) of such Guarantor, and each Guarantor is able to pay all of its liabilities as such liabilities mature and each Guarantor does not have unreasonably small capital within the meaning of
Section 548, Title 11, United States Code, as amended. In computing the amount of contingent or liquidated liabilities, such liabilities have been computed at the amount which, in light of all the facts and circumstances
existing as of the date hereof, represents the amount that can reasonably be expected to become an actual or matured liability. 
 22. If
any provision of this Guaranty is held to be illegal, invalid, or unenforceable in any jurisdiction, such provision shall be fully severable, and for purposes of such jurisdiction only, this Guaranty shall be construed and enforced as if such
illegal, invalid, or unenforceable provision had never comprised a part hereof, and in all cases the remaining provisions hereof shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or
by its severance herefrom. Furthermore, in lieu of such illegal, invalid, or unenforceable provision there shall be added automatically as a part of this Guaranty a provision as similar in terms to such illegal, invalid, or unenforceable provision
as may be possible, and be legal, valid and enforceable. 
 23. (a) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY OR ANY
OTHER LOAN DOCUMENT SHALL BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, IN EITHER CASE LOCATED IN NEW YORK COUNTY, NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS
AGREEMENT, EACH GUARANTOR HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH GUARANTOR HEREBY IRREVOCABLY WAIVES ANY OBJECTION,
INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW 

  
 7 

 
OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND
DOES NOT PRECLUDE ANY BENEFICIARY FROM OBTAINING JURISDICTION OVER ANY GUARANTOR IN ANY COURT OTHERWISE HAVING JURISDICTION. 

(b) EACH GUARANTOR IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR
PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT, c/o VPROP Operating, LLC, 4413 Carey Street, Fort Worth, Texas 76119, Attention: Martin Robinson, Facsimile No.[###-###-####], SUCH
SERVICE TO BECOME EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF ANY BENEFICIARY TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANY
GUARANTOR IN ANY OTHER JURISDICTION. 
 (c) To the extent that any Guarantor has or hereafter may acquire any immunity from
jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, such Guarantor hereby irrevocably
waives such immunity in respect of its obligations under this Guaranty and the other Loan Documents. 
 24. THIS GUARANTY AND THE OTHER LOAN
DOCUMENTS COLLECTIVELY REPRESENT THE FINAL AGREEMENT BY EACH GUARANTOR REGARDING THE MATTERS SET FORTH HEREIN AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE BENEFICIARIES AND ANY GUARANTOR.
THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE BENEFICIARIES AND ANY GUARANTOR. 
 25. EACH GUARANTOR, FOR ITSELF, ITS SUCCESSORS AND
