Notwithstanding any judgment in a currency (“Judgment Currency”) other than the Agreement Currency, a Borrower shall discharge its

​

obligation in respect of any sum due under a Loan Document only if, on the Business Day following receipt by Agent of payment in the Judgment Currency, Agent can use the amount paid to purchase the sum originally due in the Agreement Currency. If the purchased amount is less than the sum originally due, such Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify Agent and Lenders against such loss. If the purchased amount is greater than the sum originally due, Agent shall return the excess amount to such Borrower (or to the Person legally entitled thereto).

. All computations of interest for U.S. Base Rate Loans (including pursuant to clause (c) of the definition of U.S. Base Rate) shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed.  All other computations of interest, as well as fees and other charges calculated on a per annum basis, shall be computed for the actual days elapsed, based on a year of 360 days. Each determination by Agent of any interest, fee, interest rate or amounts payable hereunder shall be final, conclusive and binding for all purposes, absent manifest error. All fees shall be fully earned when due and shall not be subject to rebate, refund or proration. All fees payable under Section 3.2 are compensation for services and are not, and shall not be deemed to be, interest or any other charge for the use, forbearance or detention of money. A certificate as to amounts payable by any Borrower under Section 3.4, 3.6, 3.7, 3.9 or 5.8 that is submitted to Borrower Agent by Agent or the affected Lender shall be final, conclusive and binding for all purposes, absent manifest error, and Borrowers shall pay such amounts to the appropriate party within 10 days following receipt of the certificate.

. Obligors shall pay all Claims promptly upon written request (including by email), subject to Section 14.2.

Obligors acknowledge that

​

counsel may provide Agent with a benefit (such as a discount, credit or accommodation for other matters) based on counsel’s overall relationship with Agent, including fees paid hereunder. If, for any reason (including inaccurate information in Borrower Materials), it is determined that a higher Applicable Margin should have applied to a period than was actually applied, then the proper margin shall be applied retroactively and Borrower(s) of each affected Borrower Group shall immediately pay to Agent, for the ratable benefit of Lenders, an amount equal to the difference between the amount of interest and fees that would have accrued using the proper margin and the amount actually paid. All amounts payable by Obligors under this Section shall be due within five days of written demand therefor (including by email).

. If any Lender determines that any Applicable Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund Loans whose interest is determined by reference to a Relevant Rate, or any Governmental Authority has imposed material restrictions on the authority of such Lender to determine or charge interest rates based on a Relevant Rate or to purchase or sell, or take deposits of, any Agreed Currency in the applicable intrabank market, then, on notice thereof by such Lender to Agent, any obligation of such Lender to make or continue such Relevant Rate Loans or to convert Base Rate Loans to Relevant Rate Loans shall be suspended until such Lender notifies Agent that the circumstances giving rise to such determination no longer exist. Upon delivery of such notice, (a) U.S. Borrowers shall, in the case of all U.S. Loans bearing interest based on the Relevant Rate, prepay or, if applicable, convert all such Relevant Rate Loans of such Lender to U.S. Base Rate Loans, in each case, immediately, or on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Relevant Rate Loans to such day, and (b) U.K. Borrowers shall, in the case of all U.K. Loans bearing interest based on a Relevant Rate, prepay all such Relevant Rate Loans, in each case, immediately or on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Relevant Rate Loans to such day. Upon any such prepayment or conversion, Borrowers shall also pay accrued interest on the amount so prepaid or converted.

​

then, on a date and time determined by Agent (any such date, “Term SOFR Replacement Date”), which date shall be at the end of an Interest Period or on the relevant interest payment date, as applicable, for interest calculated and, solely with respect to clause (b) above, no later than the Term SOFR Scheduled Unavailability Date, Term SOFR will be replaced hereunder and under any other applicable Loan Document with Daily Simple SOFR plus the SOFR Adjustment, for any payment period for interest calculated that can be determined by Agent, in each case, without any amendment to, or further action or consent of any other party to, any Loan Document (“Term SOFR Successor Rate”).  If the Term SOFR Successor Rate is Daily Simple SOFR plus the SOFR Adjustment, all interest will be payable on a monthly basis.

Notwithstanding anything to the contrary herein, (x) if Agent determines that Daily Simple SOFR is not available on or prior to the Term SOFR Replacement Date or (y) if the events or circumstances of the type described in clauses (a) or (b) above have occurred with respect to the Term SOFR Successor Rate then in effect, then in each case, Agent and Borrower Agents may amend this Agreement solely for the purpose of replacing Term SOFR or any then current Term SOFR Successor Rate in accordance with this Section at the end of any Interest Period, relevant interest payment date or payment period for interest calculated, as applicable, with an alternative benchmark rate giving due consideration to any evolving or then existing convention for such alternative benchmarks in similar U.S. dollar denominated syndicated credit facilities syndicated and agented in the U.S.  and, in each case, including any mathematical or other adjustments to such benchmark giving due consideration to any evolving or then existing convention for such

​

benchmarks in similar U.S. dollar denominated credit facilities syndicated and agented in the U.S., which adjustment or method for calculating such adjustment shall be published on an information service selected by Agent from time to time in its reasonable discretion and may be periodically updated. For the avoidance of doubt, any such proposed rate and adjustments shall constitute a Term SOFR Successor Rate. Any such amendment shall become effective at 5:00 p.m. on the fifth Business Day after Agent shall have posted such proposed amendment to all Lenders and Borrower Agents unless, prior to such time, Lenders comprising the Required Lenders have delivered to Agent written notice that such Required Lenders object to such amendment.

Agent will promptly (in one or more notices) notify the Borrower Agents and each Lender of the implementation of any Term SOFR Successor Rate.  Any Term SOFR Successor Rate shall be applied in a manner consistent with market practice; provided, that to the extent such market practice is not administratively feasible for Agent, such Term SOFR Successor Rate shall be applied in a manner as otherwise reasonably determined by Agent.  Notwithstanding anything else herein, if at any time any Term SOFR Successor Rate as so determined would otherwise be less than zero, the Term SOFR Successor Rate will be deemed to be zero for the purposes of this Agreement and the other Loan Documents.

Thereafter, (x) the obligation of the Lenders to make or maintain such Loans in the affected currencies, as applicable, or to convert U.K. Base Rate Loans to Relevant Rate Loans, shall be suspended in each case to the extent of the affected Relevant Rate Loans or Interest Period or determination date(s), as applicable, and (y) in the event of a determination described in the preceding sentence with respect to any component of the U.K. Base Rate, the utilization of such component in determining the U.K. Base Rate shall be suspended, in each case until Agent (or, in the case of a determination by the Required Lenders described in clause (ii) of this Section 3.6.3(a), until Agent upon instruction of the Required Lenders) revokes such notice.

​

Upon receipt of such notice, (i) the U.K. Borrowers may revoke any pending request for a Borrowing of, or conversion to Relevant Rate Loans, or Borrowing of, or continuation of Relevant Rate Loans to the extent of the affected Alternative Currency or Interest Period or determination date(s), as applicable or, failing that, will be deemed to have converted such request into a request for a Borrowing of U.K. Base Rate Loans denominated in Dollars in the Dollar Equivalent of the amount specified therein and (ii) any outstanding affected Relevant Rate Loans, at the U.K. Borrower Agent’s election, shall either (A) be converted into a Borrowing of U.K. Base Rate Loans denominated in Dollars in the Dollar Equivalent of the amount of such outstanding Relevant Rate Loan immediately at the end of the applicable Interest Period or (B) be prepaid in full immediately at the end of the applicable Interest Period; provided that if no election is made by the U.K. Borrower Agent by the last day of the current Interest Period, the U.K. Borrower Agent shall be deemed to have elected clause (A) above.

or if the events or circumstances of the type described in Section 3.6.3(b)(i), (ii) or (iii) have occurred with respect to the Alternative Currency Successor Rate then in effect, then, Agent and the U.K. Borrower Agent may amend this Agreement solely for the purpose of replacing the Relevant Rate for an Alternative Currency or any then current Alternative Currency Successor Rate for an Alternative Currency in accordance with this Section 3.6.3 with an alternative benchmark rate giving due consideration to any evolving or then existing convention for similar credit facilities syndicated and agented in the U.S. and

​

denominated in such Alternative Currency for such alternative benchmarks, and, in each case, including any mathematical or other adjustments to such benchmark giving due consideration to any evolving or then existing convention for similar credit facilities syndicated and agented in the U.S. and denominated in such Alternative Currency for such benchmarks, which adjustment or method for calculating such adjustment shall be published on an information service as selected by Agent from time to time in its reasonable discretion and may be periodically updated (and any such proposed rate, including for the avoidance of doubt, any adjustment thereto, an “Alternative Currency Successor Rate”), and any such amendment shall become effective at 5:00 p.m. on the fifth Business Day after Agent shall have posted such proposed amendment to all Lenders and the U.K. Borrower Agent unless, prior to such time, Lenders comprising the Required Lenders have delivered to Agent written notice that such Required Lenders object to such amendment.

Agent will promptly (in one or more notices) notify the U.K. Borrower Agent and each Lender of the implementation of any Alternative Currency Successor Rate.

Any Alternative Currency Successor Rate shall be applied in a manner consistent with market practice; provided that to the extent such market practice is not administratively feasible for Agent, such Alternative Currency Successor Rate shall be applied in a manner as otherwise reasonably determined by Agent.

Notwithstanding anything else herein, if at any time any Alternative Currency Successor Rate as so determined would otherwise be less than zero, the Alternative Currency Successor Rate will be deemed to be zero for the purposes of this Agreement and the other Loan Documents.

In connection with the implementation of an Alternative Currency Successor Rate, Agent will have the right to make Alternative Currency Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Alternative Currency Conforming Changes will become effective without any further action or consent of any other party to this Agreement; provided that, with respect to any such amendment effected, Agent shall post each such amendment implementing such Alternative Currency Conforming Changes to the U.K. Borrower Agent and the Lenders reasonably promptly after such amendment becomes effective.

​

and the result thereof shall be to increase the cost to a Lender of making or maintaining any Loan or its Commitment, or converting to or continuing any interest option for a Loan, or to increase the cost to a Lender or Issuing Bank of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by a Lender or Issuing Bank hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or Issuing Bank, Borrowers will pay to it such additional amount(s) as will compensate it for the additional costs incurred or reduction suffered.  Such Lender or Issuing Bank shall deliver to Borrowers the certificate contemplated by Section 3.3.

. If any Lender gives a notice under Section 3.5 or requests compensation under Section 3.7, or if any Borrower is required to pay any Indemnified Taxes or additional amounts with respect to a Lender under Section 5.8, then at the request of Borrower Agent, such Lender shall use reasonable efforts to designate or assign its obligations hereunder to a different Lending Office, if, in the judgment of such Lender, such designation or assignment would eliminate the need for such notice or reduce amounts payable or to be withheld in the future, would not subject the Lender to any unreimbursed cost or expense, and would not otherwise be disadvantageous to it or unlawful. Borrowers of each affected Borrower Group shall pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

​

. If for any reason (a) any Borrowing, conversion or continuation of a Term SOFR Loan does not occur on the date specified therefor in a Notice of Borrowing or Notice of Conversion/Continuation (whether or not withdrawn but other than in respect of a Defaulting Lender), (b) any repayment or conversion of a Term SOFR Loan occurs on a day other than the end of its Interest Period or tenor, (c) Borrowers of any Borrower Group fail to repay a Term SOFR Loan when required, or (d) a Lender (other than a Defaulting Lender) is required to assign a Term SOFR Loan prior to the end of its Interest Period or tenor pursuant to Section 13.4, then Borrowers of such Borrower Group shall pay to Agent its customary administrative charge and to each Lender all losses, expenses and fees arising from redeployment of funds or termination of match funding.

. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by Applicable Law (“maximum rate”). If Agent or any Lender shall receive interest in an amount that exceeds the maximum rate, the excess interest shall be applied to the principal of the Obligations of the Borrower Group to which such excess interest relates or, if it exceeds such unpaid principal, refunded to such Borrower Group. In determining whether the interest contracted for, charged or received by Agent or a Lender exceeds the maximum rate, such Person may, to the extent permitted by Applicable Law, (a) characterize any payment that is not principal as an expense, fee or premium rather than interest; (b) exclude voluntary prepayments and the effects thereof; and (c) amortize, prorate, allocate and spread (in equal or unequal parts) the total amount of interest throughout the contemplated term of the Obligations hereunder.

​

​

​

. Notwithstanding anything herein to the contrary:

​

. Each Borrowing of Term SOFR Loans when made shall be in a minimum amount of $1,000,000, plus an increment of $100,000 in excess thereof. No more than six Borrowings of Term SOFR Loans may be outstanding at any time, and all Term SOFR Loans having the same length and beginning date of their Interest Periods shall be aggregated together and considered one Borrowing for this purpose. Upon determining Term SOFR for any Interest Period requested by Borrowers, Agent shall promptly notify Borrowers thereof by telephone or electronically and, if requested by Borrowers, shall confirm any telephonic notice in writing.

. Each U.S. Borrower hereby designates Helix (“U.S. Borrower Agent”), and each U.K. Borrower hereby designates Well Ops U.K. (“U.K. Borrower Agent”), as its representative and agent for all purposes under the Loan Documents, including requests for and receipt of Loans and Letters of Credit, designation of interest rates, delivery or receipt of Communications, delivery of Borrower Materials, payment of Obligations, requests for waivers, amendments or other accommodations, actions under the Loan Documents (including in respect of compliance with covenants), and all other dealings with Agent, Issuing Bank or any Lender. Each Borrower Agent hereby accepts such appointment. Agent and Lenders shall be entitled to rely upon any Communication (including any notice of borrowing) delivered by or to a Borrower Agent on behalf of any Borrower. Each of Agent, Issuing Bank and Lenders shall have the right, in its discretion, to deal exclusively with any Borrower Agent for all purposes under the Loan Documents. Each Obligor agrees that any Communication, delivery, action, omission or undertaking by a Borrower Agent shall be binding upon and enforceable against such Obligor.

. The Loans, LC Obligations and other Obligations constitute one general obligation of Borrowers, jointly and severally, and are secured by Agent’s Lien on all Collateral; provided, that Agent and each Lender shall be deemed to be a creditor of, and the holder of a separate claim against, each Borrower to the extent of any Obligations jointly or severally owed by such Borrower.

. On the effective date of the termination of all Commitments, the Obligations shall be immediately due and payable, and each Secured Bank Product Provider may terminate its Bank Products. Until Full Payment of the Obligations, all undertakings of Obligors contained in the Loan Documents shall continue, and Agent shall retain its Liens in the Collateral and all of its rights and remedies under the Loan Documents. Agent shall not be required to terminate its Liens unless it receives Cash Collateral or a written agreement, in each case satisfactory to it, protecting Agent and Lenders from dishonor or return of any Payment Item previously applied to the Obligations. Sections 2.2, 3.4, 3.6, 3.7, 3.9, 4.1.3(c), 5.4, 5.8, 5.9, Section 12, 14.2, this Section, and each indemnity or waiver given by an Obligor or Lender in any Loan Document, shall survive any assignment by

​

Agent, Issuing Bank or any Lender of rights or obligations hereunder, termination of any Commitment, and any repayment, satisfaction, discharge or Full Payment of any Obligations.

. All payments of Obligations shall be made in the applicable Agreed Currency, without offset, counterclaim or defense of any kind, free and clear of (and without deduction for) any Taxes, and in immediately available funds, not later than 12:00 noon (Local Time) on the due date. Any payment after such time shall be deemed made on the next Business Day. Any payment of a Term SOFR Loan prior to the end of its Interest Period shall be accompanied by all amounts due under Sections 3.1.1(c) and 3.9. Agent shall have the continuing, exclusive right to apply and reapply payments and proceeds of Collateral against the Obligations, at Agent’s discretion, but whenever possible any prepayment shall be applied to Base Rate Loans before Term SOFR Loans.

. Loans may be prepaid from time to time, without penalty or premium, pursuant to a Notice of Prepayment to Agent, delivered concurrently with prepayment of a Swingline Loan and at least two Business Days prior to prepayment of other Loans; provided, that no such notice shall be required for payments applied pursuant to Section 5.6 (subject to Section 3.9). All U.S. Loans shall be due and payable in full on the U.S. Commitment Termination Date and all U.K. Loans shall be due and payable in full on the U.K. Commitment Termination Date, in each case, unless payment is sooner required hereunder, and any Overadvance or Protective Advance shall be due and payable as provided in Sections 2.1.5 and 2.1.6. If any Disposition by Obligors includes Accounts, Obligors shall apply Net Proceeds to repay Loans equal to the greater of (a) the net book value (or fair market value, if higher) of such Accounts, or (b) the reduction in Borrowing Base resulting from the disposition.

. Obligations other than Loans, including LC Obligations and Claims, shall be paid by Obligors as provided in the Loan Documents or, if no payment date is specified, on demand.

. None of Agent or Lenders shall be under any obligation to marshal any assets in favor of any Obligor or against any Obligations. If any payment by or on behalf of Obligors is made to Agent, Issuing Bank or any Lender, or if Agent, Issuing Bank or any Lender exercises a right of setoff, and any of such payment or setoff is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by Agent, Issuing Bank or a Lender in its discretion) to be repaid to a trustee, receiver or any other Person, then the Obligation originally intended to be satisfied, and all Liens, rights and remedies relating thereto, shall be revived and continued in full force and effect as if such payment or setoff had not occurred.

​

Amounts shall be applied to payment of each category of Obligations only after Full Payment of amounts payable from time to time under all preceding categories. If amounts are insufficient to satisfy a category, they shall be paid ratably among outstanding Obligations in the category. Monies and proceeds obtained from an Obligor shall not be applied to its Excluded Swap Obligations, but appropriate adjustments shall be made with respect to amounts obtained from other Obligors to preserve the allocations in each category. Agent shall have no obligation to calculate the amount of any Secured Bank Product Obligation and may request a reasonably detailed calculation thereof from a Secured Bank Product Provider. If the provider fails to deliver

​

the calculation within five days following request, Agent may assume the amount is zero. The allocations in this Section are solely to determine the priorities among Secured Parties and may be changed by agreement of affected Secured Parties without the consent of any Obligor. This Section is not for the benefit of or enforceable by any Obligor, and no Obligor has any right to direct the application of payments or Collateral proceeds subject to this Section.

. The ledger balance in the U.S. Dominion Account of the U.S. Domiciled Obligors as of the end of a Business Day shall be applied to the U.S. Facility Obligations at the beginning of the next Business Day, during any Dominion Trigger Period. Subject to Section 10.1.13, the ledger balance in any U.K. Dominion Account of the U.K. Borrowers as of the end of a Business Day shall be applied to the U.K. Facility Obligations whether or not a Dominion Trigger Period exists. Any resulting credit balance shall not accrue interest in favor of Borrowers and shall be made available to Borrowers as long as no Event of Default exists, including by way of transfer to an operating account of the applicable Borrowers upon request.

. Agent shall maintain, in accordance with its customary practices, loan account(s) evidencing the Debt of Borrowers within each Borrower Group hereunder. Any failure of Agent to record anything in a loan account, or any error in doing so, shall not limit or otherwise affect the obligation of Borrowers to pay any amount owing hereunder. Entries in a loan account shall, absent manifest error, be presumptive evidence of the information contained therein. If information in a loan account is provided to or inspected by or on behalf of a Borrower, the information shall be conclusive and binding on Borrowers for all purposes absent manifest error, except to the extent Borrower Agent notifies Agent in writing within 30 days of specific information subject to dispute.

​

​

​

​

and having done so, that Lender shall be under no obligation pursuant to Section 5.8.6(b) above.

and in each case, the U.K. Borrower has notified that Lender in writing, that Lender and the U.K. Borrower shall co-operate in completing any additional procedural formalities necessary for that U.K. Borrower to obtain authorization to make that payment without a Tax Deduction.

​

​

If a New Lender fails to indicate its status in accordance with this Section 5.9.1(b), then such New Lender shall be treated for the purposes of this Agreement (including by each U.K. Borrower) as if it is not a U.K. Qualifying Lender until such time as it notifies the Agent which category of U.K. Qualifying Lender applies (and the Agent, upon receipt of such notification, shall inform the U.K. Borrower Agent).  For the avoidance of doubt, the documentation which a Lender executes on becoming a party to this Agreement as a Lender shall not be invalidated by any failure of a New Lender to comply with this Section 5.9.1(b).

​

​

​

​

​

The above limitation shall not apply to any amounts borrowed by, or made available to, in any form whatsoever, the Luxembourg Guarantor or any of its direct or indirect present or future subsidiaries under any Loan Document.

. In addition to the conditions set forth in Section 6.2, Lenders shall not be required to fund the initial requested Loan or otherwise make the initial extension of credit to Borrowers hereunder, until the date (“Closing Date”) that each of the following conditions has been satisfied or waived:

​

​

. Agent, Issuing Bank and Lenders shall not be required to make any credit extension hereunder (including funding any Loan, arranging any Letter of Credit, or granting any other accommodation to or for the benefit of any Obligor), if the following conditions are not satisfied on such date and upon giving effect thereto:

Each request (or deemed request) by a Borrower for any credit extension shall constitute a representation by Obligors that the foregoing conditions are satisfied on the date of such request and on the date of the credit extension.

​

. To secure the prompt payment and performance of the Obligations, each U.S. Domiciled Obligor hereby grants to Agent, for the benefit of Secured Parties, a continuing Lien on all of the following Property of such U.S. Domiciled Obligor, whether now owned or hereafter acquired, and wherever located:

provided, that in no event shall the above-described Property include any Excluded Property; provided, further, that Excluded Property shall not include any proceeds, products, substitutions

​

or replacements of Excluded Property, including monies due or to become due to a U.S. Domiciled Obligor (unless such proceeds, products, substitutions or replacements would otherwise constitute Excluded Property).  

To the extent that any of the above-described Property is not subject to the UCC, each U.S. Domiciled Obligor hereby pledges and collaterally assigns all of such U.S. Domiciled Obligor’s right, title, and interest in and to such Property, whether now owned or hereafter acquired, to Agent for the benefit of the Secured Parties to secure the payment and performance of the Obligations to the full extent that such a pledge and collateral assignment is possible under the relevant law and provided that such pledge is without prejudice to any rights charged, pledged or assigned pursuant to any U.K. Security Document.
