 ARTICLE II

  
 THE REVOLVING
CREDIT FACILITY 
  
 Section
2.1. The Revolving Credit Commitments. On the terms and subject to the conditions contained in this Agreement, each Lender severally agrees to make loans (each, a “Revolving Loan”) to each Borrower from time to
time on any Business Day during the period from the Effective Date until the Revolving Credit Termination Date in an aggregate amount not to exceed at any time outstanding for all such loans by such Lender such Lender’s Revolving Credit
Commitment; provided, however, that at any time no Lender shall be obligated to make a Revolving Loan to any Borrower (i) in excess of such Lender’s Ratable Portion of the Available Credit of such Borrower at such time and (ii) to
the extent that the aggregate Revolving Credit Outstandings, after giving effect to such Revolving Loans, would exceed the Maximum Credit in effect at such time. Within the limits of each Lender’s Revolving Credit Commitment, amounts of
Revolving Loans repaid may be reborrowed under this Section 2.1. 
  
 Section 2.2. Borrowing Procedures. 
  
 (a)
Each Borrowing shall be made on notice given by any Borrower to the Administrative Agent not later than 11:00 A.M. (New York City time) (i) one Business Day, in the case of a Borrowing of Base Rate Loans and (ii) three Business Days, in the case of
a Borrowing of Eurodollar Rate Loans, prior to the date of the proposed Borrowing; provided, however, in respect of Revolving Loans made on the Effective Date (x) the Notice of Borrowing (as defined below) in respect thereof may be given by
11:00 A.M. (New York City time) on the Effective Date and (y) such Revolving Loans shall be made as Base Rate Loans and thereafter 

  

 37 








 
may be converted to Eurodollar Rate Loans pursuant to Section 2.11. Each such notice shall be in substantially the form of Exhibit C (a
“Notice of Borrowing”), specifying (A) the proposed Borrower, (B) the date of such proposed Borrowing, (C) the amount of such Borrower’s Available Credit (in respect of which the Borrowing Base component thereof may be
calculated by reference to the Borrowing Base Certificate most recently delivered to the Administrative Agent hereunder), (D) the amount of the Revolving Loans then outstanding to each Borrower, (E) the aggregate amount of such proposed Borrowing,
(F) whether any portion of the proposed Borrowing will be of Base Rate Loans or Eurodollar Rate Loans and (G) the initial Interest Period or Periods for any such Eurodollar Rate Loans, if applicable. The Revolving Loans shall be made as Base Rate
Loans unless (subject to Section 2.14) the Notice of Borrowing specifies that all or a portion thereof shall be Eurodollar Rate Loans. Each Borrowing, or portion thereof, which is a Eurodollar Rate Loan shall be in an aggregate amount of not
less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof. In the event that a Borrower requests a Base Rate Loan in an amount of less than $5,000,000 the Administrative Agent may (at its option) require such Borrowing, or the
relevant portion thereof, to be made as a Swing Loan; provided, however, that to do so would not conflict with the provisions of Section 2.3. 
  
 (b) The Administrative Agent shall give to each Lender prompt notice of the Administrative Agent’s receipt of a Notice of Borrowing and, if
Eurodollar Rate Loans are properly requested in such Notice of Borrowing, the applicable interest rate determined pursuant to Section 2.14(a). Each Lender shall, before 11:00 A.M. (New York City time) on the date of the proposed Borrowing,
make available to the Administrative Agent at its address referred to in Section 11.8, in immediately available funds, such Lender’s Ratable Portion of such proposed Borrowing. After the Administrative Agent’s receipt of such funds
and upon fulfillment of the applicable conditions set forth in Sections 3.1 and 3.2, the Administrative Agent will make such funds available to the relevant Borrower in such Borrower’s Disbursement Account. 
  
 (c) Unless the Administrative Agent shall have received notice from any
Lender prior to the date of any proposed Borrowing that such Lender will not make available to the Administrative Agent such Lender’s Ratable Portion of such Borrowing, the Administrative Agent may assume that such Lender has made such Ratable
Portion available to the Administrative Agent on the date of such Borrowing in accordance with this Section 2.2 and the Administrative Agent may, in reliance upon such assumption, make available to the applicable Borrower on such date a
corresponding amount. If and to the extent that such Lender shall not have so made such Ratable Portion available to the Administrative Agent, such Lender and the applicable Borrower severally agree to repay to the Administrative Agent forthwith on
demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the applicable Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the
applicable Borrower, the interest rate applicable at the time to the Loans comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate for the first Business Day and thereafter at the interest rate applicable at the time to
the Loans comprising such Borrowing. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Loan as part of such Borrowing for purposes of this Agreement. If the
applicable Borrower shall repay to the Administrative Agent such corresponding amount, such payment shall not relieve such Lender of any obligation it may have hereunder to such Borrower. 
  
 (d) The failure of any Lender to make a Revolving Loan or any payment required by it on the date specified (a
“Non-Funding Lender”), including any payment in respect 

  

 38 








 
of its participation in Swing Loans and Letter of Credit Obligations, shall not relieve any other Lender of its obligations to make such Loan or payment on
such date but no such other Lender shall be responsible for the failure of any Non-Funding Lender to make a Revolving Loan or payment required under this Agreement. 
  
 (e) On the Effective Date, (i) all Revolving Loans under the Existing Credit Agreement shall be deemed to be Revolving Loans
outstanding under this Agreement, (ii) the Revolving Credit Commitments shall be permanently reduced from $175,000,000 to $150,000,000, (iii) that portion of the Revolving Credit Commitments of the Existing Lenders that are not party to this
Agreement shall be deemed to be assigned to the Lenders party to this Agreement, and each such Existing Lender shall cease to be a party to this Agreement, (iv) the Revolving Credit Commitment of each Lender party to the Existing Credit Agreement
that is a party to this Agreement shall be adjusted from such Lender’s revolving credit commitment under the Existing Credit Agreement to the amount set forth opposite such Lender’s name under the heading “Revolving Credit
Commitment” on Schedule I and (v) each Lender whose Ratable Portion of the Revolving Loans outstanding on the Effective Date exceeds the amount of the Revolving Loans held by it on such date shall purchase Revolving Loans from such other
Lenders such that after giving effect to such purchase, each Lender shall hold Revolving Loans equal to its Ratable Portion of the Revolving Loans outstanding on such date. 
  
 Section 2.3. Swing Loans. 
  
 (a) On the terms and subject to the conditions contained in this Agreement, the Swing Loan Lender may in its sole discretion
make loans (each, a “Swing Loan”) otherwise available to any Borrower under the Revolving Credit Facility from time to time on any Business Day during the period from the Effective Date until the Revolving Credit Termination Date in
an aggregate amount at any time outstanding at any time not to exceed the lesser of (i) $15,000,000 and (ii) the Swing Loan Lender’s Ratable Portion of the amount by which the Maximum Credit exceeds the Revolving Credit Outstandings at such
time; provided, however, that no Swing Loan may be made that, after giving effect thereto, would result in a Borrowing Base Deficiency. The Swing Loan Lender shall be entitled to rely on the most recent Borrowing Base Certificate
delivered to the Administrative Agent. Each Swing Loan shall be a Base Rate Loan and (subject to Sections 2.6 and 2.9) shall be repaid upon any Borrowing of a Revolving Loan or from time to time at the discretion of the Swing Loan
Lender but in any event no later than the Scheduled Termination Date. Within the limits set forth in the first sentence of this Section 2.3(a), amounts of Swing Loans repaid may be reborrowed under this Section 2.3(a). 
  
 (b) In order to request a Swing Loan, the relevant Borrower shall telecopy to
the Swing Loan Lender a duly completed request setting forth the requested amount and date of the Swing Loan (a “Swing Loan Request”), to be received by the Swing Loan Lender not later than 1:00 p.m. (New York City time) on the day
of the proposed Borrowing. Subject to the terms of this Agreement, the Swing Loan Lender shall make its Swing Loan available to the Borrower on the date of the relevant Swing Loan Request. The Swing Loan Lender shall not make any Swing Loan in the
period commencing on the first Business Day after it receives written notice from any Lender that one or more of the conditions precedent contained in Section 3.2 shall not on such date be satisfied, and ending when such conditions are
satisfied. The Swing Loan Lender shall not otherwise be required to determine that, or take notice whether, the conditions precedent set forth in Section 3.2 hereof have been satisfied in connection with the making of any Swing Loan.

  

 39 








 (c) The Swing Loan Lender may demand at any time that each Lender pay to the Swing Loan Lender (for its
account), in the manner provided in subsection (d) below, such Lender’s Ratable Portion of all or a portion of the outstanding Swing Loans, which demand shall be in writing and shall specify the outstanding principal amount of Swing
Loans demanded to be paid. 
  
 (d) Each demand referred to in
clause (c) above to each Lender shall be accompanied by a statement prepared by the Swing Loan Lender specifying the amount of each Lender’s Ratable Portion of the aggregate principal amount of the Swing Loans stated to be outstanding in
such notice or demanded to be paid pursuant to such demand, and, notwithstanding whether or not the conditions precedent set forth in Section 3.2 shall have been satisfied (which conditions precedent the Lenders for this purpose hereby
irrevocably waive), each Lender shall, before 11:00 a.m. (New York City time) on the Business Day next succeeding the date of such Lender’s receipt of such written statement, make available to the Swing Loan Lender, in immediately available
funds, for the account of the Swing Loan Lender, the amount specified in such statement. Upon such payment by a Lender, such Lender shall, except as provided in clause (f) below, be deemed to have made a Revolving Loan to the applicable
Borrower. The Swing Loan Lender shall use such funds to repay the Swing Loans owing to it. To the extent that any Lender fails to make such payment available to the Swing Loan Lender, the applicable Borrower shall repay such Swing Loan on demand.

  
 (e) Upon the occurrence of a Default under Section
9.1(g), each Lender shall acquire, without recourse or warranty, an undivided participation in each Swing Loan otherwise required to be repaid by such Lender pursuant to clause (d) above, which participation shall be in a principal amount
equal to such Lender’s Ratable Portion of such Swing Loan, by paying to the Swing Loan Lender on the date on which such Lender would otherwise have been required to make a payment in respect of such Swing Loan pursuant to clause (d)
above, in immediately available funds, an amount equal to such Lender’s Ratable Portion of such Swing Loan. If such amount is not in fact made available by such Lender to the Swing Loan Lender on such date, the Swing Loan Lender shall be
entitled to recover such amount on demand from such Lender together with interest accrued from such date at the Federal Funds Rate for the first Business Day after such payment was due and thereafter at the rate of interest then applicable to Base
Rate Loans. 
  
 (f) From and after the date on which any Lender is
deemed to have made a Revolving Loan pursuant to clause (d) above with respect to any Swing Loan or purchases an undivided participation interest in a Swing Loan pursuant to clause (e) above, the Swing Loan Lender shall promptly
distribute to such Lender such Lender’s Ratable Portion of all payments of principal of and interest received by the Swing Loan Lender on account of such Swing Loan other than those received from a Lender pursuant to clause (d) or
(e) above. 
  

 40 








 Section 2.4. Letters of Credit. 
  
 (a) On the terms and subject to the conditions contained in this Agreement,
each Issuer agrees to issue one or more Letters of Credit at the request of any Borrower for the account of such Borrower from time to time during the period commencing on the Effective Date and ending on the earlier of the Revolving Credit
Termination Date and 30 days prior to the Scheduled Termination Date; provided, however, that no Issuer shall be under any obligation to issue any Letter of Credit if: 
  
 (i) any order, judgment or decree of any Governmental Authority or arbitrator shall purport by its terms to
enjoin or restrain such Issuer from issuing such Letter of Credit or any Requirement of Law applicable to such Issuer or any request or directive (whether or not having the force of law but in relation with which such Issuer customarily complies)
from any Governmental Authority with jurisdiction over such Issuer shall prohibit, or request that such Issuer refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon such Issuer with
respect to such Letter of Credit any restriction or reserve or capital requirement (for which such Issuer is not otherwise compensated) not in effect on the date of this Agreement or result in any unreimbursed loss, cost or expense which was not
applicable, in effect or known to such Issuer as of the date of this Agreement and which such Issuer in good faith deems material to it; 
  
 (ii) such Issuer shall have received written notice from the Administrative Agent, any Lender or the applicable Borrower, on or prior to
the requested date of issuance of such Letter of Credit, that one or more of the applicable conditions contained in Sections 3.1 and 3.2 is not then satisfied; 
  
 (iii) after giving effect to the issuance of such Letter of Credit, (A) the aggregate Revolving Credit
Outstandings would exceed the Maximum Credit in effect at such time or (B) a Borrowing Base Deficiency would result with respect to any Borrower; 
  
 (iv) after giving effect to the issuance of such Letter of Credit, the sum of (i) the Letter of Credit Undrawn Amounts at such time and
(ii) the Reimbursement Obligations at such time exceeds $50,000,000 (the “Letter of Credit Sublimit”); or 
  
 (v) any fees due in connection with a requested issuance have not been paid. 
  
 None of the Lenders (other than the Issuers in their capacity as such) shall have any obligation to issue any Letter of Credit. 

 
 (b) In no event shall the expiration date of any Letter of Credit be more
than one year after the date of issuance thereof; provided, however, that (i) any Letter of Credit with a one-year term may provide for the renewal thereof for additional one-year periods and (ii) by not later than the Revolving Credit
Termination Date each Borrower shall provide cash collateral in respect of any outstanding Letters of Credit issued for its account at such date in accordance with Section 9.3. 
  
 (c) In connection with the issuance of each Letter of Credit, the applicable Borrower shall give the relevant Issuer and the
Administrative Agent at least two Business Days’ prior written notice (a “Letter of Credit Request”), in substantially the form of Exhibit D (or in such other written or electronic form as is acceptable to the Issuer),
of the requested issuance of such Letter of Credit. Such notice shall be irrevocable and shall specify the applicable Borrower, the Issuer of such Letter of Credit, the stated amount of the Letter of Credit requested, the date of issuance of such
requested Letter of Credit (which day shall be a Business Day), the date on which such Letter of Credit is to expire (which date shall be a Business Day), and the Person for whose benefit the requested Letter of Credit is to be issued. Such notice,
to be effective, must be 

  

 41 








 
received by the relevant Issuer and the Administrative Agent not later than 11:00 A.M. (New York City time) on the second Business Day prior to the requested
issuance of such Letter of Credit. 
  
 (d) Subject to the
satisfaction of the conditions set forth in this Section 2.4, the relevant Issuer shall, on the requested date, issue a Letter of Credit on behalf of any Borrower in accordance with such Issuer’s usual and customary business practices.
No Issuer shall issue any Letter of Credit in the period commencing on the first Business Day after it receives written notice from any Lender that one or more of the conditions precedent contained in Section 3.2 shall not on such date be
satisfied, and ending when such conditions are satisfied. The relevant Issuer shall not otherwise be required to determine that, or take notice whether, the conditions precedent set forth in Section 3.2 have been satisfied in connection with
the issuance of any Letter of Credit. 
  
 (e) If requested by the
relevant Issuer, prior to the issuance of each Letter of Credit by such Issuer, and as a condition of such issuance and of the participation of each Lender in the Letter of Credit Obligations arising with respect thereto, the applicable Borrower
shall have delivered to such Issuer a letter of credit reimbursement agreement, in such form as the Issuer may employ in its ordinary course of business for its own account (a “Letter of Credit Reimbursement Agreement”), signed by
the applicable Borrower, and such other documents or items as may be required pursuant to the terms thereof. In the event of any conflict between the terms of any Letter of Credit Reimbursement Agreement and this Agreement, the terms of this
Agreement shall govern. 
  
 (f) Each Issuer shall: 
  
 (i) give the Administrative Agent written notice (or notice
by telephone, confirmed promptly thereafter in writing, which may be by telecopier) of the issuance or renewal of a Letter of Credit issued by it, of all drawings under a Letter of Credit issued by it and the payment (or the failure to pay when due)
by the applicable Borrower of any Reimbursement Obligation when due (which notice the Administrative Agent shall promptly transmit by telecopy or similar transmission to each Lender). 
  
 (ii) upon the request of any Lender, furnish to such Lender copies of any Letter of Credit Reimbursement
Agreement to which such Issuer is a party and such other documentation as may reasonably be requested by such Lender; and 
  
 (iii) no later than the first Business Day following the last day of each calendar month, provide to the Administrative Agent (and the
Administrative Agent shall provide a copy to each Lender requesting the same) and the Borrowers separate schedules for Documentary and Standby Letters of Credit issued by it, in form and substance reasonably satisfactory to the Administrative Agent,
setting forth the aggregate Letter of Credit Obligations outstanding at the end of each month and any information requested by the Borrowers or the Administrative Agent relating thereto. 
  
 (g) Immediately upon the issuance by an Issuer of a Letter of Credit in accordance with the terms and conditions of this
Agreement, such Issuer shall be deemed to have sold and transferred to each Lender, and each Lender shall be deemed irrevocably and unconditionally to have purchased and received from such Issuer, without recourse or warranty, an undivided interest
and participation, to the extent of such Lender’s Ratable Portion of the 

  

 42 








 
Revolving Credit Commitments, in such Letter of Credit and the obligations of the Borrowers with respect thereto (including all Letter of Credit Obligations
with respect thereto) and any security therefor and guaranty pertaining thereto. 
  
 (h) Each Borrower agrees to pay to the Issuer of any Letter of Credit the amount of all Reimbursement Obligations owing to such Issuer under any Letter of Credit issued for its account when such amounts are due and
payable, irrespective of any claim, set-off, defense or other right which such Borrower may have at any time against such Issuer or any other Person. In the event that any Issuer makes any payment under any Letter of Credit and such Borrower shall
not have repaid such amount to such Issuer pursuant to this clause (h) above or such payment is rescinded or set aside for any reason, such Reimbursement Obligation shall be payable on demand with interest thereon computed from the date on
which such Reimbursement Obligation arose to the date of repayment in full at the rate of interest applicable to past due Revolving Loans bearing interest at a rate based on the Base Rate during such period, and such Issuer shall promptly notify the
Administrative Agent, which shall promptly notify each Lender of such failure, and each Lender shall promptly and unconditionally pay to the Administrative Agent for the account of such Issuer the amount of such Lender’s Ratable Portion of such
payment in Dollars and in immediately available funds. If the Administrative Agent so notifies such Lender prior to 11:00 A.M. (New York City time) on any Business Day, such Lender shall make available to the Administrative Agent for the account of
such Issuer its Ratable Portion of the amount of such payment on such Business Day in immediately available funds. Upon such payment by a Lender, such Lender shall, except during the continuance of a Default or Event of Default under Section
9.1(g) and notwithstanding whether or not the conditions precedent set forth in Section 3.2 shall have been satisfied (which conditions precedent the Lenders hereby irrevocably waive) be deemed to have made a Revolving Loan to the
applicable Borrower in the principal amount of such payment. Whenever any Issuer receives from a Borrower a payment of a Reimbursement Obligation as to which the Administrative Agent has received for the account of such Issuer any payment from a
Lender pursuant to this clause (h) above, such Issuer shall pay to the Administrative Agent and the Administrative Agent shall promptly pay to each Lender, in immediately available funds, an amount equal to such Lender’s Ratable Portion
of the amount of such payment adjusted, if necessary, to reflect the respective amounts the Lenders have paid in respect of such Reimbursement Obligation. 
  
 (i) Each Borrower’s obligation to pay each Reimbursement Obligation and the obligations of the Lenders to make payments to the Administrative Agent
for the account of the Issuers with respect to Letters of Credit shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, under any and all circumstances whatsoever, including
the occurrence of any Default or Event of Default, and irrespective of: 
  
 (i) any lack of validity or enforceability of any Letter of Credit or any Loan Document, or any term or provision therein; 
  
 (ii) any amendment or waiver of or any consent to departure from all or any of the provisions of any Letter of Credit or any Loan
Document; 
  
 (iii) the existence of any claim,
set off, defense or other right that any Borrower, any Loan Party, or other party guaranteeing, or otherwise obligated with, such Borrower, any Subsidiary or other Affiliate thereof or any other Person may at any time have against the beneficiary
under any Letter of Credit, Issuer, the Administrative Agent 

  

 43 








 
or any Lender or any other Person, whether in connection with this Agreement, any other Loan Document or any other related or unrelated agreement or
transaction; 
  
 (iv) any draft or other document
presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; 
  
 (v) payment by the Issuer under a Letter of Credit against presentation of a draft or other document that
does not comply with the terms of such Letter of Credit; and 
  
 (vi) any other act or omission to act or delay of any kind of the Issuer, the Lenders, the Administrative Agent or any other Person or any other event or circumstance whatsoever, whether or not similar to any of the
foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of any Borrower’s obligations hereunder. 
  
 Any action taken or omitted to be taken by the relevant Issuer under or in connection with any Letter of Credit, if taken or omitted in the absence of gross negligence or
willful misconduct, shall not put such Issuer under any resulting liability to any Borrower or any Lender. In determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof, the Issuer may accept
documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary and, in making any payment under any Letter of Credit the Issuer may rely exclusively on
the documents presented to it under such Letter of Credit as to any and all matters set forth therein, including reliance on the amount of any draft presented under such Letter of Credit, whether or not the amount due to the beneficiary thereunder
equals the amount of such draft and whether or not any document presented pursuant to such Letter of Credit proves to be insufficient in any respect, if such document on its face appears to be in order, and whether or not any other statement or any
other document presented pursuant to such Letter of Credit proves to be forged or invalid or any statement therein proves to be inaccurate or untrue in any respect whatsoever and any noncompliance in any immaterial respect of the documents presented
under such Letter of Credit with the terms thereof shall, in each case, be deemed not to constitute willful misconduct or gross negligence of the Issuer. 
  
 (j) If and to the extent such Lender shall not have so made its Ratable Portion of the amount of the payment required by clause (i) above available
to the Administrative Agent for the account of such Issuer, such Lender agrees to pay to the Administrative Agent for the account of such Issuer forthwith on demand such amount together with interest thereon, for the first Business Day after payment
was first due at the Federal Funds Rate, and thereafter until such amount is repaid to the Administrative Agent for the account of such Issuer, at the rate per annum applicable to Base Rate Loans under the Revolving Credit Facility. The failure of
any Lender to make available to the Administrative Agent for the account of such Issuer its Ratable Portion of any such payment shall not relieve any other Lender of its obligation hereunder to make available to the Administrative Agent for the
account of such Issuer its Ratable Portion of any payment on the date such payment is to be made, but no Lender shall be responsible for the failure of any other Lender to make available to the Administrative Agent for the account of the Issuer such
other Lender’s Ratable Portion of any such payment. 
  

 44 








 Section 2.5. Reduction and Termination of the Revolving Credit Commitments. The
Borrowers may upon at least three Business Days’ prior notice to the Administrative Agent, terminate in whole or reduce in part ratably the unused portions of the respective Revolving Credit Commitments of the Lenders; provided,
however, that each partial reduction shall be in the aggregate amount of not less than $10,000,000 or an integral multiple of $5,000,000 in excess thereof. 
  

Section 2.6. Repayment of Loans. Each Borrower shall repay the entire unpaid principal amount of its Revolving Loans on the
Scheduled Termination Date. 
  
 Section 2.7. Evidence of
Debt, Obligations of Borrowers. 
  
 (a) Each Lender shall
maintain in accordance with its usual practice an account or accounts evidencing Indebtedness of each Borrower to such Lender resulting from each Loan of such Lender from time to time, including the amounts of principal and interest payable and paid
to such Lender from time to time under this Agreement. 
  
 (b) The
Administrative Agent shall maintain accounts in accordance with its usual practice in which it will record (i) the amount of each Loan made and, if a Eurodollar Rate Loan, the Interest Period applicable thereto, (ii) the amount of any principal or
interest due and payable by each Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder from each Borrower and each Lender’s share thereof, if applicable. 
  
 (c) The entries made in the accounts maintained pursuant to clauses
(a) and (b) of this Section 2.7 shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations recorded therein; provided, however, that the failure of
any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrowers to repay the Loans in accordance with their terms. 
  
 (d) Notwithstanding any other provision of the Agreement, in the event that
any Lender requests that any Borrower execute and deliver a promissory note or notes payable to such Lender in order to evidence the Indebtedness owing to such Lender by such Borrower hereunder, each such Borrower will promptly execute and deliver a
Note or Notes to such Lender evidencing any Revolving Loans of such Lender, substantially in the form of Exhibit B, and the interests evidenced by such note or notes shall at all times (including after assignment of all or part of such
interests) be evidenced by one or more Notes payable to the order of the payee named therein; provided, however, that Terra UK shall not be required to execute and deliver any promissory note or notes hereunder and that each Existing Lender
that was issued a Note previously shall be issued a new Note to reflect the amendment and restatement of the Existing Credit Agreement and any change in the Revolving Credit Commitments of such Existing Lender. 
  
 (e) Without affecting any guaranty or collateral obligation of any Borrower
or other Loan Party under any Loan Document, each Borrower is severally liable in respect of its Obligations hereunder (in respect of principal and interest only) and, as a Borrower, is not obligated in such capacity to repay any Loan (or pay
interest thereon) of another Borrower hereunder. All other Obligations of the Borrowers hereunder are joint and several.

 Section 2.8. Optional Prepayments. The Borrowers may (in addition to the obligations
under Section 2.9(e)), upon, (i) in respect of Swing Loans, same day notice, (ii) in respect of Base Rate Loans, at least one Business Day’s prior notice, and (iii) in respect of Eurodollar Rate Loans, at least four Business Days’
prior notice, to the Administrative Agent, stating the proposed date and aggregate principal amount of the prepayment, prepay the outstanding principal amount of the Revolving Loans in whole or in part; provided, however, that if any
prepayment of any Eurodollar Rate Loan is made by any Borrower other than on the last day of an Interest Period for such Loan, such Borrower shall also pay any amounts owing pursuant to Section 2.14(e); and, provided, further,
that each partial prepayment (other than in respect of Swing Loans or as required under Section 2.9) shall be in an aggregate principal amount not less than $5,000,000 or integral multiples of $1,000,000 in excess thereof. Upon the giving of
such notice of prepayment, the principal amount of Loans specified to be prepaid shall become due and payable on the date specified for such prepayment. 
  
 Section 2.9. Mandatory Prepayments. 
  
 (a) Upon receipt by Terra Industries, the Borrowers or any of their respective Subsidiaries of Net Cash Proceeds (other than, with respect to MCC and its
Subsidiaries to the extent that (x) the administrative agent and the lenders under the MCC Credit Agreement have a first priority Lien on and right to such Net Cash Proceeds pursuant to the MCC Intercreditor Agreements and (y) such Net Cash Proceeds
are used to prepay the MCC Credit Agreement) arising (i) from an Asset Sale or a Debt Issuance, each Borrower shall immediately prepay its Loans (or provide cash collateral in respect of Letters of Credit) such that the aggregate amount of all such
payments is equal to 100% of such Net Cash Proceeds, (ii) from an Equity Issuance each Borrower shall immediately prepay its Loans (or provide cash collateral in respect of Letters of Credit) such that the aggregate amount of all such payments is
equal to 50% of such Net Cash Proceeds, or (iii) from an insured loss or casualty event (being, other than proceeds in respect of business interruption, “Insurance Proceeds”), each Borrower shall immediately prepay its Loans (or
provide cash collateral in respect of Letters of Credit) such that the aggregate amount of all such payments is equal to 100% of such Net Cash Proceeds; provided, however, any Insurance Proceeds (which do not exceed $20,000,000 in
respect of any single loss or event) may (provided, and for so long as, no Default or Event of Default shall have occurred and be continuing), at the request of the Borrowers, be applied in replacing or reinstating the affected assets; provided
further that (A) such Net Cash Proceeds are so applied (or contractually committed to be so applied) within 360 days (the “Reinstatement Date”) following the occurrence of the event giving rise to such Net Cash Proceeds, (B)
such Net Cash Proceeds are deposited in a Cash Collateral Account maintained with, and subject to a perfected first priority Lien in favor of, the Administrative Agent (which cash collateral may be included in the calculation of relevant Borrowing
Base pending its application hereunder) and (notwithstanding Section 11.1(a)(ix)) any Net Cash Proceeds deposited in such account for such purpose may not subsequently be withdrawn without the approval of the Administrative Agent and (C) any
such Net Cash Proceeds or any portion thereof not applied in replacement or reinstatement of the affected assets (x) by the Reinstatement Date or (y) at any time during the continuance of a Default or Event of Default at any time prior to the
Reinstatement Date, shall be applied as mandatory prepayment of the Loans (or as cash collateral in respect of Letters of Credit) at such time. Any such mandatory prepayment shall be applied in accordance with Section 2.9(c) below.

  
 (b) Any prepayments made by the Borrowers required to be
applied in accordance with this Section 2.9 shall be applied as follows: first, to repay the outstanding 

  

 46 








 
principal balance of the Swing Loans until such Swing Loans shall have been repaid in full; second, to repay the outstanding principal balance of the
Revolving Loans until such Revolving Loans shall have been paid in full; and then, to provide cash collateral for any Letter of Credit Obligations in the manner set forth in Section 9.3 until all such Letter of Credit Obligations have
been fully cash collateralized in the manner set forth therein. 
  
 (c) If at any time, either (i) the aggregate principal amount of Revolving Credit Outstandings exceeds the Maximum Credit at such time or (ii) a Borrowing Base Deficiency exists in respect of any Borrower, each Borrower shall forthwith (or
if such Borrowing Base Deficiency has occurred through Accounts which were previously classified as Eligible Receivables being reclassified as ineligible, in which case upon the expiration of two Business Days during which such Borrowing Base
Deficiency remains continuing) prepay its Swing Loans first and then its Revolving Loans then outstanding such that the aggregate amount of all such payments is equal to such excess or otherwise sufficient to eliminate such deficiency. If any such
excess or deficiency remains after repayment in full of the aggregate outstanding Swing Loans and Revolving Loans, each Borrower shall provide cash collateral for its Letter of Credit Obligations in the manner set forth in Section 9.3 to the
extent required to eliminate such excess or deficiency. 
  
 (d)
Each Borrower agrees that all available funds (others than those funds representing Net Cash Proceeds which are to be otherwise applied pursuant to this Section 2.9) in a Cash Collateral Account of such Borrower shall (subject, in the case of
Terra UK, to Section 7.12(d)(iii)) be applied on a daily basis; first to repay the outstanding principal amount of its Swing Loans until its Swing Loans shall have been repaid in full; second to repay the outstanding principal
balance of its Revolving Loans until its Revolving Loans shall have been repaid in full; and third to any other Obligations then due and payable. If there are no Loans outstanding and no other Obligations are then due and payable, then the
funds in such Cash Collateral Account shall be retained in such Cash Collateral Account, or (if required by the Administrative Agent) transferred to the L/C Cash Collateral Account, to cash collateralize the Letter of Credit Obligations then
outstanding and any contingent obligations which such Borrower may have under any Guaranty); provided, however, that (subject to the consent of the Administrative Agent in accordance with Section 7.12(d)(iii) in respect of Terra
UK) if on any Business Day after giving effect to the foregoing applications any funds are on deposit in its Cash Collateral Account and no Default or Event of Default shall have occurred and be continuing, the applicable Borrower may direct the
Administrative Agent to (and the Administrative Agent shall) disburse such funds to such Borrower’s Disbursement Account. 
  
 Section 2.10. Interest. 
  
 (a) Rate of Interest. All Loans and the outstanding amount of all other Obligations shall bear interest, in the case of Loans, on the unpaid
principal amount thereof from the date such Loans are made and, in the case of such other Obligations, from the date such other Obligations are due and payable until, in all cases, paid in full, except as otherwise provided in Section
2.10(c), as follows: 
  
 (i) if a Base Rate
Loan or such other Obligation, at a rate per annum equal to the sum of (A) the Base Rate as in effect from time to time, plus (B) the Applicable Margin; and 
  

 47 








 (ii) if a Eurodollar Rate Loan, at a rate per annum equal to the sum of (A) the
Eurodollar Rate determined for the applicable Interest Period, plus (B) the Applicable Margin in effect from time to time during such Eurodollar Interest Period. 
  
 (b) Interest Payments. (i) Interest accrued on each Base Rate Loan (including Swing Loans) shall be payable in
arrears (A) on the first day of each calendar month, commencing on the first such day following the making of such Base Rate Loan, and (B) if not previously paid in full, at maturity (whether by acceleration or otherwise) of such Base Rate Loan;
(ii) interest accrued on each Eurodollar Rate Loan shall be payable in arrears (A) on the last day of each Interest Period applicable to such Loan and, in respect of any Interest Period of six months’ duration, on the day which is three months
following commencement of such Interest Period and also on the last day of such Interest Period, (B) upon the payment or prepayment thereof in full or in part, and (C) if not previously paid in full, at maturity (whether by acceleration or
otherwise) of such Eurodollar Rate Loan; and (iii) interest accrued on the amount of all other Obligations shall be payable on demand from and after the time such Obligation, becomes due and payable (whether by acceleration or otherwise).

  
 (c) Default Interest. Notwithstanding the rates of
interest specified in Section 2.10(a) or elsewhere herein, effective immediately upon the occurrence of an Event of Default, and for as long thereafter as such Event of Default shall be continuing, the principal balance of all Loans and the
amount of all other Obligations shall bear interest at a rate which is two percent per annum in excess of the rate of interest applicable to such Obligations from time to time. 
  
 Section 2.11. Conversion/Continuation Option. 
  
 (a) The Borrowers may elect (i) at any time to convert Base Rate Loans (other than Swing Loans) or any portion thereof to
Eurodollar Rate Loans, or (ii) at the end of any applicable Interest Period, to convert Eurodollar Rate Loans or any portion thereof into Base Rate Loans or to continue such Eurodollar Rate Loans or any portion thereof for an additional Interest
Period; provided, however, that the aggregate amount of the Eurodollar Loans for each Interest Period complies with the provisions of Section 2.2(a). Each conversion or continuation shall be allocated among the Loans of each Lender in
accordance with its Ratable Portion. Each such election shall be in substantially the form of Exhibit F hereto (a “Notice of Conversion or Continuation”) and shall be made by giving the Administrative Agent at least three
Business Days’ prior written notice specifying (A) the amount and type of Loan being converted or continued, (B) in the case of a conversion to or a continuation of Eurodollar Rate Loans, the applicable Interest Period, and (C) in the case of a
conversion, the date of conversion (which date shall be a Business Day and, if a conversion from Eurodollar Rate Loans, shall also be the last day of the applicable Interest Period). 
  
 (b) The Administrative Agent shall promptly notify each Lender of its receipt of a Notice of Conversion or Continuation and
of the options selected therein. Notwithstanding the foregoing, no conversion in whole or in part of Base Rate Loans to Eurodollar Rate Loans, and no continuation in whole or in part of Eurodollar Rate Loans upon the expiration of any applicable
Interest Period, shall be permitted at any time at which (i) a Default or an Event of Default shall have occurred and be continuing or (ii) the continuation of, or conversion into, would violate any of the provisions of Section 2.14. If,
within the time period required under the terms of this Section 2.11, the Administrative Agent does not receive a Notice 

  

 48 








 
of Conversion or Continuation from any Borrower containing a permitted election to continue any Eurodollar Rate Loans for an additional Interest Period or to
convert any such Loans, then, upon the expiration of the applicable Interest Period, such Loans will be automatically converted to Base Rate Loans. Each Notice of Conversion or Continuation shall be irrevocable. 
  
 Section 2.12. Fees. 
  
 (a) Unused Commitment Fee. The Borrowers agree to pay to each Lender a
commitment fee on the actual amount by which the Revolving Credit Commitment of such Lender exceeds the sum of (i) such Lender’s Ratable Portion of the outstanding Revolving Loans and outstanding Letter of Credit Obligations and (ii) the
outstanding portion of any Swing Loans made by such Lender (the “Unused Commitment Fee”) on each day from the date hereof until the Revolving Credit Termination Date equal to 0.50% per annum, payable in arrears (x) on the first day
of each calendar month, commencing on the first such day following the date of this Agreement and (y) on the Revolving Credit Termination Date. 
  
 (b) Letter of Credit Fees. The Borrowers agree to pay the following amounts with respect to Letters of Credit issued by any Issuer: 
  
 (i) to the Administrative Agent for the account of each
Issuer of a Letter of Credit, with respect to each Letter of Credit issued by such Issuer, an issuance fee equal to 0.50% per annum of the maximum amount available from time to time to be drawn under such Letter of Credit, payable in arrears (A) on
the first day of each calendar month, commencing on the first such day following the issuance of such Letter of Credit and (B) on the Revolving Credit Termination Date; 
  
 (ii) to the Administrative Agent for the ratable benefit of the Lenders, with respect to each Letter of
Credit, a fee accruing at a rate per annum equal to the Applicable Margin for Revolving Loans that are Eurodollar Rate Loans of the maximum amount available from time to time to be drawn under such Letter of Credit, payable in arrears (A) on the
first day of each calendar month commencing on the first such day following the issuance of such Letter of Credit and (B) on the Revolving Credit Termination Date; provided, however that during the continuance of an Event of Default, such fee
shall be increased by two percent per annum and shall be payable on demand; and 
  
 (iii) to the Issuer of any Letter of Credit, with respect to the issuance, amendment or transfer of each Letter of Credit and each drawing
made thereunder, documentary and processing charges in accordance with such Issuer’s standard schedule for such charges in effect at the time of issuance, amendment, transfer or drawing, as the case may be. 
  
 (c) Additional Fees. The Borrowers have agreed to pay to the Lenders,
the Administrative Agent and the Arranger additional fees, the amount and dates of payment of which are embodied in the Fee Letter. Any cash management fees payable by or on behalf of any Loan Party shall be payable irrespective of whether accounts
are opened in the name of any Loan Party or by the Administrative Agent or any of its Affiliates in its name in respect of any Loan Party. 
  

 49 








 Section 2.13. Payments and Computations; Protective Advances. 
  
 (a) The Borrowers shall make each payment hereunder (including fees and
expenses) not later than 11:00 A.M. (New York City time) (provided, however, that repayments of Swing Loans shall be made not later than 4:00 P.M. (New York City time)) on the day when due, in Dollars, to the Administrative Agent at its
address referred to in Section 11.8 in immediately available funds without set-off or counterclaim. The Administrative Agent will promptly thereafter cause to be distributed immediately available funds relating to the payment of principal or
interest or fees to the Lenders, in accordance with the application of payments set forth in clauses (e) and (f) of this Section 2.13, as applicable, for the account of their respective Applicable Lending Offices;
provided, however, that amounts payable pursuant to Section 2.14(c), 2.14(e), 2.15 or 2.16 shall be paid only to the affected Lender or Lenders and amounts payable with respect to Swing Loans shall be paid
only to the Swing Loan Lender. Payments received by the Administrative Agent after 11:00 A.M. (New York City time) shall be deemed to be received on the next Business Day. 
  
 (b) All computations of interest and fees shall be made by the Administrative Agent on the basis of a year of 360 days, in
each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest and fees are payable. Each determination by the Administrative Agent of an interest rate hereunder shall be
conclusive and binding for all purposes, absent manifest error. 
  
 (c) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of
payment of interest or fees, as the case may be; provided, however, that if such extension would cause payment of interest on or principal of any Eurodollar Rate Loan to be made in the next calendar month, such payment shall be made on
the immediately preceding Business Day. All repayments of any Revolving Loans shall be applied first to repay such Loans outstanding as Base Rate Loans and then to repay such Loans outstanding as Eurodollar Rate Loans with those Eurodollar Rate
Loans which have earlier expiring Eurodollar Interest Periods being repaid prior to those which have later expiring Eurodollar Interest Periods. 
  
 (d) Unless the Administrative Agent shall have received notice from the Borrowers to the Lenders prior to the date on which any payment is due hereunder
that the Borrowers will not make such payment in full, the Administrative Agent may assume that the Borrowers have made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption,
cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Borrowers shall not have made such payment in full to the Administrative Agent, each Lender shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon at the Federal Funds Rate, for the first Business Day, and, thereafter, at the rate applicable to Base Rate Loans, for each day from the
date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent. 
  
 (e) Subject to the provisions of clause (f) of this Section 2.13 and (except as otherwise provided in Section 2.9), all payments and
any other amounts received by the Administrative Agent from or for the benefit of any Borrower shall be applied first, to pay 

  

 50 








 
principal of and interest on any portion of the Loans which the Administrative Agent may have advanced to such Borrower pursuant to the express provisions of
this Agreement on behalf of any Lender, for which the Administrative Agent has not then been reimbursed by such Lender or such Borrower; second, to pay all other Obligations owing by such Borrower then due and payable; and third, as
such Borrower so designate. Payments in respect of Swing Loans received by the Administrative Agent shall be distributed to the Swing Loan Lender; payments in respect of Revolving Loans received by the Administrative Agent shall be distributed to
each Lender in accordance with such Lender’s Ratable Portion of the Revolving Credit Commitments; and all payments of fees and all other payments in respect of any other Obligation shall be allocated among such of the Lenders and Issuers as are
entitled thereto, and, if to the Lenders, in proportion to their respective Ratable Portions. 
  
 (f) After the occurrence and during the continuance of an Event of Default, each Borrower hereby irrevocably waives the right to direct the application of any and all payments in respect of the Obligations owing by
such Borrower and any proceeds of Collateral of such Borrower, and agrees that the Administrative Agent may, and shall upon either (A) the written direction of the Requisite Lenders or (B) the acceleration of the Obligations pursuant to Section
9.2, apply all payments in respect of any Obligations and all funds on deposit in any Cash Collateral Account (including all proceeds arising in connection with a Reinstatement Date that are held in the Cash Collateral Account pending
application of such proceeds as specified in Section 2.9(a)) and all other proceeds of Collateral in the following order: 
  
 (i) first, to pay interest on and then principal of any portion of the Revolving Loans which the Administrative Agent may have
advanced on behalf of any Lender for which the Administrative Agent has not then been reimbursed by such Lender or the Borrowers;  
  
 (ii) second, to pay interest on and then principal of any Swing Loan; 
  
 (iii) third, to pay Obligations in respect of any
expense reimbursements or indemnities then due the Administrative Agent; 
  
 (iv) fourth, to pay Obligations in respect of any expense reimbursements or indemnities then due to the Lenders and the Issuers; 
  
 (v) fifth, to pay Obligations in respect of any fees then due to the Administrative Agent, the
Lenders and the Issuers; 
  
 (vi) sixth,
to pay interest then due and payable in respect of the Revolving Loans and Reimbursement Obligations; 
  
 (vii) seventh, to pay or prepay principal payments on the Revolving Loans and Reimbursement Obligations and to provide cash
collateral for outstanding Letter of Credit Undrawn Amounts in the manner described in Section 9.3, and to pay Obligations owing to the Administrative Agent with respect to cash management services in connection with Approved Deposit
Accounts, Cash Collateral Accounts, and any other collection, disbursement or payroll account, ratably to the aggregate principal amount of such Revolving Loans, Reimbursement Obligations and Letter of Credit Undrawn Amounts and amounts due in
respect of such cash management services; 
  

 51 








 (viii) eighth, to the ratable payment of all Obligations owing to any Lender or
any Affiliate of a Lender with respect to Hedging Contracts; and 
  
 (ix) ninth, to the ratable payment of all other Obligations; 
  
 provided, however, that if sufficient funds are not available to fund all payments to be made in respect of any of the Obligations described in any of the foregoing clauses first through
eighth, the available funds being applied with respect to any such Obligations (unless otherwise specified in such clause) shall be allocated to the payment of such Obligations ratably, based on the proportion of the Administrative
Agent’s and each Lender’s or Issuer’s interest in the aggregate outstanding Obligations described in such clauses. The order of priority set forth in clauses first through eighth of this Section 2.13(f) may at any
time and from time to time be changed by the agreement of the Requisite Lenders without necessity of notice to or consent of or approval by the Borrower, any Secured Party that is not a Lender or Issuer, or any other Person. The order of priority
set forth in clauses first through fifth of this Section 2.13(f) may be changed only with the prior written consent of the Administrative Agent in addition to the Requisite Lenders. 
  
 (g) All payments of Reimbursement Obligations, interest, fees, expenses and
other sums due and payable in respect of the Loans of any Borrower and all expenses, disbursements and advances incurred by the Administrative Agent pursuant to the Loan Documents after the occurrence and during the continuance of an Event of
Default which the Administrative Agent, in its sole discretion, deems necessary or desirable to preserve or protect the Collateral of such Borrower or any portion thereof or to enhance the likelihood or maximize the amount of repayment of the
Obligations owing by such Borrower may, at the option of the Administrative Agent, be paid from the proceeds of Swing Loans or Revolving Loans. Each Borrower hereby authorizes the Swing Loan Lender to make Swing Loans pursuant to Section
2.3(a) and the Lenders to make Revolving Loans pursuant to Section 2.2(a), from time to time in the Swing Loan Lender’s or such Lender’s discretion, which are in the amounts of any and all principal payable with respect to the
interest, fees, expenses and other sums payable in respect of the Loans of such Borrower, and further authorizes the Administrative Agent to give the Lenders notice of any Borrowing with respect to such Loans and to distribute the proceeds of such
Loans to pay such amounts. Each Borrower agrees that all such Loans so made shall be deemed to have been requested by it, as applicable, (irrespective of the satisfaction of the conditions in Section 3.2, which conditions the Lenders
irrevocably waive) and directs that all proceeds thereof shall be used to pay such amounts. 
  
 Section 2.14. Special Provisions Governing Eurodollar Rate Loans. 
  
 (a) Determination of Interest Rate. The Eurodollar Rate for each Interest Period for Eurodollar Rate Loans shall be determined by the
Administrative Agent pursuant to the procedures set forth in the definition of “Eurodollar Rate.” The Administrative Agent’s determination shall be presumed to be correct, absent manifest error, and shall be binding on the
Borrowers. 
  
 (b) Interest Rate Unascertainable, Inadequate or
Unfair. In the event that: (i) the Administrative Agent reasonably determines that adequate and fair means do not exist for ascertaining the applicable interest rates by reference to which the Eurodollar Rate then being determined is to be
fixed; or (ii) the Requisite Lenders notify the Administrative Agent that the Eurodollar Rate for any Interest Period will not adequately reflect the cost to the Lenders of making or maintaining such Loans for such Interest Period, the
Administrative Agent shall 

  

 52 








 
forthwith so notify the Borrowers and the Lenders, whereupon each Eurodollar Loan will automatically, on the last day of the current Interest Period for such
Loan, convert into a Base Rate Loan and the obligations of the Lenders to make Eurodollar Rate Loans or to convert Base Rate Loans into Eurodollar Rate Loans shall be suspended until the Administrative Agent shall notify the Borrowers that the
Requisite Lenders have determined that the circumstances causing such suspension no longer exist. 
  
 (c) Increased Costs. If at any time any Lender shall reasonably determine that the introduction of or any change (where such introduction or change
occurs after the date of this Agreement) in or in the interpretation of any law, treaty or governmental rule, regulation or order (other than any change by way of imposition or increase of reserve requirements included in determining the Eurodollar
Rate Reserve Percentage and other than any change in the rate of tax on, or determined by reference to, the net income or profits of such Lender (including franchise taxes) or capital of such Lender) or the compliance by such Lender with any
guideline, request or directive (where such guideline, request or directive is issued after the date of this Agreement) from any central bank or other Governmental Authority (whether or not having the force of law but in relation to which such
Lender customarily complies), there shall be any increase in the cost to such Lender of agreeing to make or making, funding or maintaining any Eurodollar Rate Loans made to any Borrower, then such Borrower shall from time to time, upon demand by
such Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost. A certificate as to the amount of
such increased cost, submitted to the applicable Borrower and the Administrative Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest error. 
  
 (d) Illegality. Notwithstanding any other provision of this Agreement, if any Lender determines that the introduction
of or any change in or in the interpretation of any law, treaty or governmental rule, regulation or order after the date of this Agreement shall make it unlawful, or any central bank or other Governmental Authority shall assert that it is unlawful,
for any Lender or its Eurodollar Lending Office to make Eurodollar Rate Loans or to continue to fund or maintain Eurodollar Rate Loans, then, on notice thereof and demand therefor by such Lender to the Borrowers through the Administrative Agent, (i)
the obligation of such Lender to make or to continue Eurodollar Rate Loans and to convert Base Rate Loans into Eurodollar Rate Loans shall be suspended, and each such Lender shall make a Base Rate Loan as part of any requested Borrowing of
Eurodollar Rate Loans and (ii) if the affected Eurodollar Rate Loans are then outstanding, each applicable Borrower shall immediately (or, if lawful to do so, on the last day of the current Interest Period relating thereto) convert each such Loan
into a Base Rate Loan. If at any time after a Lender gives notice under this Section 2.14(d) such Lender determines that it may lawfully make Eurodollar Rate Loans, such Lender shall promptly give notice of that determination to the
applicable Borrower and the Administrative Agent, and the Administrative Agent shall promptly transmit the notice to each other Lender. Each Borrower’s right to request, and such Lender’s obligation, if any, to make Eurodollar Rate Loans
shall thereupon be restored. 
  
 (e) Breakage Costs. In
addition to all amounts required to be paid by the Borrowers pursuant to Section 2.10, each Borrower shall compensate each Lender, upon demand, for all losses, expenses and liabilities (including any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by such Lender to fund or maintain such Lender’s Eurodollar Rate Loans to such Borrower but excluding any loss of the Applicable Margin on the relevant Loans) which that Lender may
sustain (i) if for any reason 

  

 53 








 
(other than under Section 2.14(b)) a proposed Borrowing, conversion into or continuation of Eurodollar Rate Loans does not occur on a date specified
therefor in a Notice of Borrowing or a Notice of Conversion or Continuation given by such Borrower or in a telephonic request by it for borrowing or conversion or continuation or a successive Interest Period does not commence after notice therefor
is given pursuant to Section 2.11, (ii) if for any reason any Eurodollar Rate Loan is prepaid (including mandatorily pursuant to Section 2.9) on a date which is not the last day of the applicable Interest Period, (iii) as a consequence
of a required conversion of a Eurodollar Rate Loan to a Base Rate Loan as a result of any of the events indicated in Section 2.14(d), or (iv) as a consequence of any failure by a Borrower to repay Eurodollar Rate Loans when required by the
terms hereof. The Lender making demand for such compensation shall deliver to the applicable Borrower concurrently with such demand a written statement as to such losses, expenses and liabilities, and this statement shall be conclusive as to the
amount of compensation due to that Lender, absent manifest error. 
  
 (f) Excluded Period. No Lender or Issuer shall be entitled to make a claim under Clauses 2.14(c), 2.15 or 2.16 unless it has notified the Administrative Agent of its intention to make such claim within 180 days
of such Lender or Issuer becoming aware of the circumstances giving rise to such claim. 
  
 Section 2.15. Capital Adequacy. If at any time any Lender reasonably determines that (a) the adoption of or any change in or in the interpretation of any law, treaty or governmental rule,
regulation or order after the date of this Agreement regarding capital adequacy, (b) compliance with any such law, treaty, rule, regulation, or order, or (c) compliance with any guideline or request or directive issued after the date hereof from any
central bank or other Governmental Authority (whether or not having the force of law) shall have the effect of reducing the rate of return on such Lender’s (or any corporation controlling such Lender’s) capital as a consequence of its
obligations hereunder or under or in respect of any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change, compliance or interpretation, then, upon demand from time to time by
such Lender (with a copy of such demand to the Administrative Agent), the applicable Borrower shall pay to the Administrative Agent for the account of such Lender, from time to time as specified by such Lender, additional amounts sufficient to
compensate such Lender for such reduction. A certificate as to such amounts submitted to the applicable Borrower and the Administrative Agent by such Lender shall be conclusive and binding for all purposes absent manifest error. 
  
 Section 2.16. Taxes. 
  
 (a) Subject to Section 2.16(f) below, any and all payments by the
Borrowers under each Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding (i) in the
case of each Lender and the Administrative Agent (A) taxes imposed on or measured by its net income, and franchise taxes imposed on it, by the jurisdiction (or any political subdivision thereof) under the laws of which such Lender or the
Administrative Agent (as the case may be) is organized or in which it maintains any office or operations and (B) any United States withholding taxes payable with respect to payments under the Loan Documents under laws (including any statute, treaty
or regulation) in effect on the Initial Closing Date (or, in the case of an Eligible Assignee, the date of the Assignment and Acceptance) applicable to such Lender or the Administrative Agent, as the case may be, but not excluding any United States
withholding payable as a result of any change in such laws occurring after the 

  

 54 








 
Initial Closing Date (or the date of such Assignment and Acceptance) (but excluding taxes set forth in clause (A) above) and (ii) in the case of each Lender,
taxes imposed on or measured by its net income, and franchise taxes imposed on it, by the jurisdiction in which such Lender’s Applicable Lending Office is located (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings
and liabilities being hereinafter referred to as “Taxes”). If any Taxes shall be required by law to be deducted from or in respect of any sum payable by any Borrower under any Loan Document to any Lender or the Administrative Agent
(i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.16) such Lender or the Administrative Agent (as the case
may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall make such deductions, (iii) such Borrower shall pay the full amount deducted to the relevant taxing authority or other
authority in accordance with applicable law, and (iv) such Borrower shall deliver to the Administrative Agent evidence of such payment. 
  
 (b) In addition, each Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar
levies of the United States or any political subdivision thereof or any applicable foreign jurisdiction, and all liabilities with respect thereto, which arise from any payment made by such Borrower or any of its Subsidiaries under any Loan Document
or from the execution, delivery or registration of, or otherwise with respect to, any Loan Document (collectively, “Other Taxes”). 
  
 (c) Each Borrower will indemnify each Lender and the Administrative Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes
imposed by any jurisdiction on amounts payable under this Section 2.16) paid by such Lender or the Administrative Agent (as the case may be) and any liability (including for penalties, interest and expenses) arising therefrom or with respect
thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This indemnification shall be made within 30 days from the date such Lender or the Administrative Agent (as the case may be) makes written demand therefor.

or ECI as appropriate including any required certifications) or other applicable form, certificate or document prescribed by the IRS certifying as to such Non-U.S. Lender’s entitlement to such exemption from United States withholding tax with
respect to all payments to be made to such Non-U.S. Lender under the Loan Documents. Unless the Borrowers and the Administrative Agent have received forms or other documents satisfactory to them indicating that payments under any Loan Document to or
for a Non-U.S. 

  

 55 








 
Lender are not subject to United States withholding tax, the Borrowers or the Administrative Agent shall withhold taxes from such payments at the applicable
statutory rate. 
  
 (g) Any Lender claiming any additional amounts
payable pursuant to this Section 2.16 shall use its reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Applicable Lending Office if the making of such a change
would avoid the need for, or reduce the amount of, any such additional amounts which would be payable or may thereafter accrue and would not, in the sole determination of such Lender, be otherwise disadvantageous to such Lender. If any Lender is
not, with reasonable efforts, able to change the jurisdiction of its Applicable Lending Office in accordance with this Section 2.16(g), then such Lender shall use its reasonable efforts to complete such tax forms and make such filings as
would avoid the need for, or reduce the amount of, any such additional amounts which would be payable or may thereafter accrue; provided, however, that completion of such forms and making of such filings would not in the sole
discretion of such Lender be disadvantageous to it. 
  
 (h) (i) As
at the date of this Agreement, the Administrative Agent and each Lender represents and warrants to the Loan Parties that (to the extent that any payments are to be made to it hereunder by Terra UK) it is a Qualifying Lender, (ii) if a Lender ceases
to be a Qualifying Lender (except as a result of the introduction of, change in, or change in the interpretation, administration or application of, any law or regulation or any practice or concession of the United Kingdom Inland Revenue occurring
after the date of this Agreement) or any transfer, sale, negotiation or assignment is made pursuant to Section 11.2 to a non-Qualifying Lender, then the Loan Parties shall not be liable to pay any amount under Section 2.16(a) in excess
of the amount which it would have been obliged to pay if that Lender had remained a Qualifying Lender. Each Lender shall notify the Administrative Agent who in turn shall notify Terra Capital as soon as reasonably practicable after it becomes aware
that it has ceased to be a Qualifying Lender. 
  
 Section 2.17.
Substitution of Lenders. In the event that (a) (i) any Lender makes a claim under Section 2.14 (c) or Section 2.15, or (ii) it becomes illegal for any Lender to continue to fund or make any Eurodollar Rate Loan
and such Lender notifies the Borrowers pursuant to Section 2.14(d), or (iii) the Borrowers are required to make any payment pursuant to Section 2.16 that is attributable to any Lender, or (iv) any Lender is a Non-Funding Lender, (b) in
the case of clause (a)(i) above, as a consequence of increased costs in respect of which such claim is made, the effective rate of interest payable to such Lender under this Agreement with respect to its Loans materially exceeds the effective
average annual rate of interest payable to the Requisite Lenders under this Agreement and (c) Lenders holding at least 75% of the Revolving Credit Commitments are not subject to such increased costs or illegality, payment or proceedings (any such
Lender, an “Affected Lender”), the Borrowers may substitute another financial institution for such Affected Lender hereunder, upon reasonable prior written notice (which written notice must be given within 90 days following the
occurrence of any of the events described in clauses (a)(i), (ii), (iii) or (iv)) by the Borrowers to the Administrative Agent and the Affected Lender that the Borrowers intend to make such substitution, which substitute
financial institution must be an Eligible Assignee and, if not a Lender, reasonably acceptable to the Administrative Agent; provided, however, that if more than one Lender claims increased costs, illegality or right to payment arising
from the same act or condition and such claims are received by the Borrowers within 30 days of each other then the Borrowers may substitute all, but not (except to the extent the Borrowers have already substituted one of such Affected Lenders before
the Borrowers’ 

  

 56 








 
receipt of the other Affected Lenders’ claim) less than all, Lenders making such claims. In the event that the proposed substitute financial institution
or other entity is reasonably acceptable to the Administrative Agent and the written notice was properly issued under this Section 2.17, the Affected Lender shall sell and the substitute financial institution or other entity shall purchase,
pursuant to an Assignment and Acceptance, all rights and claims of such Affected Lender under the Loan Documents and the substitute financial institution or other entity shall assume and the Affected Lender shall be relieved of its Revolving Credit
Commitments and all other prior unperformed obligations of the Affected Lender under the Loan Documents (other than in respect of any damages (other than exemplary or punitive damages, to the extent permitted by applicable law) in respect of any
such unperformed obligations). Upon the effectiveness of such sale, purchase and assumption (which, in any event shall be conditioned upon the payment in full by the Borrowers to the Affected Lender in cash of all fees, unreimbursed costs and
expenses and indemnities accrued and unpaid through such effective date), the substitute financial institution or other entity shall become a “Lender” hereunder for all purposes of this Agreement having a Revolving Credit Commitment
(if applicable) in the amount of such Affected Lender’s Revolving Credit Commitment assumed by it and such Revolving Credit Commitment (if applicable) of the Affected Lender shall be terminated, provided that all indemnities under the Loan
Documents shall continue in favor of such Affected Lender. 
  
 Section 2.18. Assignment and Assumption of certain Commitments prior to the Effective Date. Pursuant to an Assignment and Acceptance effective immediately prior to the Effective Date, PNC Business Credit
(“PNC”) has sold and assigned to CUSA, and CUSA has purchased and assumed from PNC, all of PNC’s Revolving Credit Commitments and related rights and obligations under the Existing Credit Agreement (the “PNC
Interest”). Effective immediately upon the Effective Date, CUSA is hereby deemed to have sold and assigned to the other Lenders party hereto, and the Lenders are hereby deemed to have purchased and assumed from CUSA, a portion of the PNC
Interest, in each case to the extent necessary such that each Lender’s Revolving Credit Commitment on the Effective Date shall be as set forth on Schedule I with respect to such Lender.

$5,000,000 or more; 
  
 (e) any proposed acquisition of stock,
assets or real estate, or any proposed leasing of property, or any other action by any Loan Party or any of its Subsidiaries the consequences of which in the aggregate have a reasonable likelihood of subjecting the Loan Parties collectively to

or more; and 
  
 (g) upon written request by the Administrative
Agent or by any Lender through the Administrative Agent, following (i) the acquisition by a Loan Party or its Subsidiary of a fee interest in any Real Property, (ii) the occurrence of a Default or Event of Default pursuant to Section 7.10 or

environmental consulting firm reasonably acceptable to the Administrative Agent providing, as appropriate in the circumstances, an assessment of the status of any Environmental Liabilities and Costs and other environmental, health or safety
compliance, hazard or liability issue arising in relation thereto, which assessment shall be reasonable in scope in light of the circumstances, perceived risks and the facts known at the time. Without limiting the foregoing, if the Administrative
Agent determines at any time that a material risk exists that any such report will not be provided within a reasonable time following such request the Administrative Agent may retain an environmental consulting firm to prepare such report at the

Business Day if requested more frequently) executed by a Responsible Officer of each Borrower together with reasonably detailed supporting information and documentation acceptable to the Administrative Agent. The Administrative Agent shall make
reasonable efforts to furnish to the Lenders a copy of each Borrowing Base Certificate following receipt thereof from the Borrowers; provided, however, that failure to furnish such a copy will not give rise to a claim or remedy by the
Lenders against the Administrative Agent.

 77 








 
other documents and the identity of all Account Debtors in respect of Accounts referred to therein.

connection therewith. 
  
 Section 6.12. Other
Information. The Borrowers will provide the Administrative Agent or any Lender with such other information respecting the business, properties, condition, financial or otherwise, or operations of Terra Industries or any of its Subsidiaries

insurance as may be reasonably requested by the Requisite Lenders and the Administrative Agent (as a result of any report delivered pursuant to Section 6.8 or the Lenders or Administrative Agent becoming aware of any fact or circumstances
following the Initial Closing Date which would indicate that it would be prudent and consistent with industry practice for such additional insurance to be obtained), and, in any event, all insurance required by any Collateral Documents and (ii)

or the obligations under any Guaranty of such Obligations), provided, however, this clause (B) shall not apply to any Stock issued by MCHI to the extent that, and for so long as, a grant of a security interest in such Stock
(“Restricted Stock”) is prohibited by any Requirement of Law of a Governmental Authority, requires a consent not obtained of any Governmental Authority pursuant to such Requirement of Law or is prohibited by, or constitutes a breach
or default under or results in the termination of or requires any consent which has not been obtained under, any contract, license, agreement, instrument or other document evidencing or giving rise to such Stock or any applicable shareholder or
similar agreement, except to the extent that (x) such Requirement of Law or the term in such contract, license, agreement, instrument or other document or shareholder or similar agreement providing for such prohibition, breach, default or
termination or requiring such consent is ineffective under applicable law, (y) the required consent has been obtained, is no longer required or the required consent is from a Loan Party or one of its Subsidiaries, or (z) any such term in such
contract, license, agreement, instrument or other document or shareholder or similar agreement providing for such prohibition, breach, default or termination or requiring such consent was entered into by Terra Industries or its Subsidiaries after
the date hereof, and (ii) deliver to the Administrative Agent the certificates (if any) representing such Stock and Stock Equivalents and other debt Securities, together with (A) in the case of such certificated Stock and Stock Equivalents, undated
stock powers endorsed in blank, and (B) in the case of such certificated debt Securities, endorsed in blank, in each case executed and delivered by a Responsible Officer of the Borrower or such Subsidiary, as the case may be, (iii) cause such new
Material Subsidiary (other than MCHI and its Subsidiaries) (A) to become a party to a Guaranty and (B) to take such actions necessary or advisable to grant to the Administrative Agent for the benefit of the Secured Parties a perfected security
interest in the Collateral described in the Collateral Documents with respect to such new Material Subsidiary, including the filing of Uniform Commercial Code financing statements in such jurisdictions as may be required by the Collateral Documents
or by law or as may be reasonably requested by the Administrative Agent and (iv) if requested by the Administrative Agent, deliver to the Administrative Agent legal opinions relating to the matters described above, which opinions shall be in form
and substance, and from counsel, reasonably satisfactory to the Agent; provided, further, that such new Material Subsidiary (other than MCHI), if not a Domestic Subsidiary, shall only be required to guarantee and secure the Obligations
of Terra UK. 
  
 (b) Not later than the date which is 30 days
after the Effective Date (or such later date as the Administrative Agent may agree to in its sole discretion), Terra Industries and its Subsidiaries shall ensure that MCHI shall have executed and delivered to the Administrative Agent a guaranty of
the Obligations in form and substance satisfactory to the Administrative Agent, together with one or more legal opinions from counsel to the Loan Parties, and in form and substance, satisfactory to the Administrative Agent; provided, however,
that such guaranty shall contain payment subordination, standstill and turnover provisions in favor of the

 (c) Terra Industries and its Subsidiaries shall ensure that with respect to
the Ammonium Nitrate Hedging Agreement, any gas Hedging Contract and any other Hedging Contract nominated by the Administrative Agent, all payments to Terra Industries or its Subsidiaries thereunder by the applicable counterparty thereto shall be
made directly to a Cash Collateral Account or Approved Deposit Account (approved for such purpose by the Administrative Agent) and an irrevocable instruction (in form and substance satisfactory to the Administrative Agent) shall have been given by
Terra Industries or its relevant Subsidiary to such counterparty to make payments thereunder to such Cash Collateral Account or Approved Deposit Account. 
  
 (d) Promptly upon the reasonable request by the Administrative Agent, each of Terra Industries and the Borrowers shall, and shall ensure that each of its
Subsidiaries shall, take such action as the Administrative Agent may request (including the execution, amendment, delivery, filing and registration of any Loan Document or other document, certificate, agreement or instrument) in order to correct any
material defect or error which may be discovered which impairs, or may fail to provide, the intended legality, effectiveness, accuracy, perfection or priority of any Loan Document.

through or under any Loan Party shall have any control over the use of, or any right to effect a withdrawal from, any Cash Collateral Account or the US Concentration Account; provided, however, that at such times as an Account
Triggering Event shall not have occurred and be continuing in respect of any Loan Party, each of Terra UK and Terra Canada may by written notice instruct the Administrative Agent to make payments from its Cash Collateral Account to its Disbursement
Account subject to and in accordance with the provisions of clauses (d)(ii) and (iii) below. All amounts in the Cash Collateral Accounts of Terra Capital, MCC and (for Dollar denominated receivables) Terra Canada shall be
applied by the Administrative Agent as specified in clause(d)(i) below. 
  
 (c) Each Borrower and Terra Canada shall instruct its Account Debtors in respect of the Collateral to mail their remittances to a Lockbox and such Loan Party shall take all steps necessary or desirable, in the
Administrative Agent’s sole discretion, to cause such Account Debtors to mail their remittances to such Lockbox. Each Borrower and Terra Canada shall mail to its Lockbox any remittances from such Account Debtors received directly by it as soon
as possible (but in any event no later than the Business Day immediately following receipt). 
  

 82 








 (d) Notwithstanding Section 11.1(a)(ix), each Borrower shall, and shall cause Terra Canada to,
maintain a cash management system acceptable to the Administrative Agent including one or more Lockboxes as follows:

Agent within two Business Days of the deposit of any proceeds of Collateral in the US Concentration Account which portion of such proceeds is owned by Terra Capital, MCC or, if applicable, Terra Canada. All funds on deposit in the Cash Collateral
Accounts in respect of Terra Capital and MCC shall be applied in the manner specified in Section 2.9(e) and in respect of Terra Canada shall be applied as specified in clause (d)(ii)below. 
  
 (ii) In the case of Terra Canada, such cash management
system shall provide for (A) all funds received by it (other than funds constituting Senior Secured Note Collateral) to be deposited in a Lockbox or Approved Deposit Account covered by a Deposit Account Control Agreement located in New York (in
respect of US Dollar denominated account receivables) and in Sarnia, Ontario (in respect of all other account receivables), (B) daily deposit of remittances received in each Lockbox to each corresponding Approved Deposit Account, (C) daily sweeping
of the funds in the New York Approved Deposit Account to the US Concentration Account and (D) upon receipt of notice from Terra Capital (as provided in clause (d)(i) above, but subject to the last sentence of this clause (d)(ii)),
allocation and transfer of such amounts owned by Terra Canada in the US Concentration Account to a Disbursement Account of Terra Canada or as Terra Canada may otherwise instruct the Administrative Agent. Terra Canada shall notify the Administrative
Agent within two Business Days of the deposit of any proceeds of Collateral in either of the Approved Deposit Accounts. As long as no Account Triggering Event in respect of Terra Canada has occurred and is continuing, all funds on deposit in the
Lockbox or in the Approved Deposit Account of Terra Canada or in the US Concentration Account (to the extent owned by it) shall, upon written notice from Terra Canada to the Administrative Agent, be transferred to a Disbursement Account of Terra
Canada or as Terra Canada may otherwise direct. Upon and during the continuance of an Account Triggering Event in respect of Terra Canada, no amount in the Lockbox or Approved Deposit Account of Terra Canada or in the US Concentration Account (to
the extent owned by it) may be withdrawn therefrom without the approval of the Administrative Agent.

respect of Terra UK has occurred and is continuing or otherwise at the discretion of the Administrative Agent), be either: (X) applied in the manner specified in Section 2.9(e); (Y) retained in the Approved Deposit Account or (Z) if the
Administrative Agent consents (such consent not to be unreasonably withheld) following a written request of Terra UK to the Administrative Agent, be transferred to a Disbursement Account of Terra UK. Upon and during the continuance of an Account
Triggering Event in respect of Terra UK, no amount may be withdrawn from Terra UK’s Approved Deposit Account without the approval of the Administrative Agent and all funds on deposit therein shall be applied in the manner specified in
Section 2.9(e). 
  
 (e) Each Borrower and Terra Canada shall,
not later than the Effective Date (or such later date as shall be acceptable to the Administrative Agent in its sole discretion), deliver to the Administrative Agent the Deposit Account Control Agreements, covering such accounts (other than accounts
constituting Senior Secured Note Collateral) as the Administrative Agent shall direct, each duly executed by each party thereto. 
  
 (f) Any Loan Party may deposit any cash and Cash Equivalents held by it, which are not required to be applied in any other manner under the Loan Documents
or the Senior Secured Note Documents, into such collateral account as may be approved by the Administrative Agent for the purpose of including such cash or Cash Equivalents in the calculation of a Borrowing Base. The Administrative Agent shall have
a perfected first priority lien over any such account and (notwithstanding Section 11.1(a)(ix)) any cash or Cash Equivalents deposited in such account for such purpose may not subsequently be withdrawn by a Loan Party without the approval of
the Administrative Agent. 
  
 (g) The Administrative Agent may
convert into Dollars any amount not denominated in Dollars which is deposited in any Cash Collateral Account or which is otherwise received by it from or for the account of any Loan Party (which pursuant to the Loan Documents is to be applied to the
payment of the Obligations) and each Borrower hereby agrees to indemnify the Administrative Agent and each other Indemnitee (as defined in Section 11.4(a)) from and against any loss, liability, cost or expense incurred by it in connection
with such conversion and any Indemnitee entering into any currency exchange contract in the ordinary course of business for such purpose. 
  
 (h) None of Terra Industries or its Subsidiaries shall, following and during the continuance of an Account Triggering Event, a Default or Event of
Default, maintain cash or Cash Equivalents (other than in respect of those funds referred to in Section 8.3(j)) in aggregate in excess of $3,000,000 outside of those accounts which are Approved Deposit Accounts, the US Concentration Account,
Cash Collateral Accounts or accounts in which funds constituting Senior Secured Note Collateral are deposited or maintained including, without limitation, the Collateral Account (as defined in the Senior Secured Note Indenture). 
  
 Notwithstanding the foregoing, each Loan Party (other than MCC and its Subsidiaries) hereby
acknowledges that all the accounts and the cash management system set forth above have been established by the Loan Parties, as applicable, in favor of the Administrative Agent.

(p) an “Event of Default” shall have occurred and be continuing, as such term is defined in the TNLP Credit Agreement. 
  
 Section 9.2. Remedies. During the continuance of any

amounts and Obligations payable under this Agreement to be forthwith due and payable, whereupon the Loans, all such interest and all such amounts and Obligations shall become and be forthwith due and payable, without presentment, demand, protest or
further notice of any kind, all of which are hereby expressly waived by the Borrower; provided, however, that upon the occurrence of the Event of Default specified in Section 9.1(g) above (except to the extent that such Event of
Default has occurred in respect of Terra Industries and/or Terra Capital Holdings), (A) the Revolving Credit Commitments of each Lender to make Revolving Loans and of each Lender and Issuer to issue or participate in Letters of Credit shall
automatically be terminated and (B) the Loans, all such interest and all such amounts and Obligations shall automatically become and be due and payable, without presentment, demand, protest or any notice of any kind, all of which are hereby
expressly waived by the Borrowers. In addition to the remedies set forth above, the Administrative Agent may instruct the Administrative Agent, on behalf of the Secured Parties, to exercise any remedies provided for by the Collateral Documents in
accordance with the terms thereof or any other remedies provided by applicable law. 
  
 Section 9.3. Actions in Respect of Letters of Credit. Upon the Revolving Credit Termination Date or as required by Section 2.9, the Borrowers shall pay to the Administrative Agent in
immediately available funds at the Administrative Agent’s office referred to in Section 11.8, for deposit in a cash collateral account (the “L/C Cash Collateral Account”) to be maintained with and in the name of the
Administrative Agent on behalf of the Lenders at such place as shall be designated by the Administrative Agent, an amount equal to (a) 110% of the sum of all outstanding Letter of Credit Obligations which are denominated in Dollars and (b) 125% of
the sum of all outstanding Letter of Credit Obligations (if any) which are denominated in currencies other than Dollars. The Administrative Agent may, from time to time after funds are deposited in the L/C Cash Collateral Account, apply funds then
held in the L/C Cash Collateral Account to the payment of any amounts, in accordance with Section 2.13(f), as shall have become or shall become due and payable by the Borrowers to the Issuers or the Lenders in respect of the Letter of Credit
Obligations. The Administrative Agent shall promptly give written notice of any such application; provided, however, that the failure to give such written notice shall not invalidate any such application. Neither the Borrowers nor any
Person claiming on behalf of or through the Borrowers shall have any right to withdraw any of the funds held in the L/C Cash Collateral Account at any time prior to the termination of all outstanding 

  

 98 








 
Letters of Credit and the payment in full of all then outstanding and payable monetary Obligations.

termination of the Revolving Credit Commitments and/or acceleration of the maturity of the Loans, the Borrowers shall pay all arrears of interest and all payments on account of principal of the Loans and Reimbursement Obligations which shall have
become due otherwise than by acceleration (with interest on principal and, to the extent permitted by law, on overdue interest, at the rates specified herein) and all Events of Default and Defaults (other than non-payment of principal of and accrued
interest on the Loans due and payable solely by virtue of acceleration) shall be remedied or waived pursuant to Section 11.1, then upon the written consent of the Requisite Lenders and written notice to the Borrowers, the termination of the
Revolving Credit Commitments and/or the acceleration and their consequences may be rescinded and annulled; but such action shall not affect any subsequent Event of Default or Default or impair any right or remedy consequent thereon. The provisions
of the preceding sentence are intended merely to bind the Lenders and the Issuers to a decision which may be made at the election of the Requisite Lenders; they are not intended to benefit the Borrowers and do not give the Borrowers the right to
require the Lenders to rescind or annul any acceleration hereunder, even if the conditions set forth herein are met.

Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to the Administrative Agent under such agreements and to exercise such powers as are reasonably
incidental thereto. Without limitation of the foregoing, each Lender and each Issuer hereby authorizes the Administrative Agent to execute and deliver, and to perform its obligations under each of the Loan Documents to which the Administrative Agent
is a party and to exercise all rights, powers and remedies that the Administrative Agent may have under such Loan Documents and recognizes that under the Collateral Documents the Administrative Agent is acting as agent for the Secured Parties.

  
 (b) As to any matters not expressly provided for by this
Agreement and the other Loan Documents (including enforcement or collection), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully
protected in so acting or refraining from acting) upon the instructions of the Requisite Lenders, and such instructions shall be binding upon all Lenders and each Issuer; provided, however, that the Administrative Agent shall not be
required to take any action which (i) the Administrative Agent in good faith believes exposes it to personal liability unless the Administrative Agent receives an indemnification satisfactory to it from the Lenders and the Issuers with respect to
such action or (ii) is contrary to this Agreement or applicable law. The Administrative Agent agrees to give to each Lender and each Issuer prompt notice of each notice given to it by any Loan Party pursuant to the terms of this Agreement or the
other Loan Documents. 
  

 99 








 (c) In performing its functions and duties hereunder and under the other Loan Documents, the
Administrative Agent is acting solely on behalf of the Lenders and the Issuers and its duties are entirely administrative in nature. The Administrative Agent does not assume and shall not be deemed to have assumed any obligation other than as
expressly set forth herein and in the other Loan Documents or any other relationship as the agent, fiduciary or trustee of or for any Lender, Issuer or holder of any other Obligation. The Administrative Agent may perform any of its duties under any
of the Loan Documents by or through its agents or employees.

of the terms, covenants or conditions of this Agreement or any of the other Loan Documents or the financial condition of any Loan Party, or the existence or possible existence of any Default or Event of Default; (f) shall not be responsible to any
Lender or Issuer for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any of the other Loan Documents or any other instrument or document furnished pursuant hereto or thereto; and (g)

genuine and signed or sent by the proper party or parties. 
  
 Section 10.3. The Administrative Agent Individually. With respect to its Ratable Portion, CUSA shall have and may exercise the same rights and powers hereunder and is subject to the same obligations and
liabilities as and to the extent set forth herein for any other Lender. The terms “Lenders,” or “Requisite Lenders” or any similar terms shall, unless the context clearly otherwise indicates, include the
Administrative Agent in its individual capacity as a Lender or as one of the Requisite Lenders. CUSA and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of banking, trust or other business with any Loan Party
as if it were not acting as the Administrative Agent. 
  
 Section 10.4. Lender Credit Decision. Each Lender and each Issuer acknowledges that it shall, independently and without reliance upon the Administrative Agent or its Affiliates or any other Lender conduct its own
independent investigation of the financial condition and affairs of the Borrower and each other Loan Party in connection with the making and continuance of the Loans and with the issuance of the Letters of Credit. Each Lender and each Issuer also
acknowledges that it will, independently and without reliance upon the Administrative Agent or its Affiliates or any other Lender and based on such documents and 

  

 100 








 
information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and other
Loan Documents. 
  
 Section 10.5.
Indemnification. Each Lender agrees to indemnify the Administrative Agent and each of its Affiliates, and each of their respective directors, officers, employees, agents and advisors (to the extent not reimbursed by the Borrowers),
from and against such Lender’s aggregate Ratable Portion of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements (including fees and disbursements of legal counsel) of
any kind or nature whatsoever which may be imposed on, incurred by, or asserted against, the Administrative Agent or any of its Affiliates, directors, officers, employees, agents and advisors in any way relating to or arising out of this Agreement
or the other Loan Documents or any action taken or omitted by the Administrative Agent under this Agreement or the other Loan Documents; provided, however, that no Lender shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s or such Affiliate’s gross negligence or willful misconduct. Without limitation of the foregoing,
each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including fees and disbursements of legal counsel) incurred by the Administrative Agent in connection with the
preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of its rights or responsibilities under, this Agreement or the
other Loan Documents, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrowers or another Loan Party. 
  
 Section 10.6. Successor Administrative Agent. (a) Subject to clause (b) below, the Administrative Agent may resign at any time
by giving written notice thereof to the Lenders and the Borrowers. Upon any such resignation, the Requisite Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed
by the Requisite Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a
successor Administrative Agent selected from among the Lenders. Each such appointment shall be subject to the prior written approval of the Borrowers (which approval may not be unreasonably withheld and shall not be required upon the occurrence and
during the continuance of an Event of Default); (b) Notwithstanding clause (a) above, the Administrative Agent may at any time appoint any Affiliate (or Affiliates) of the Administrative Agent each as (i) a successor Administrative Agent in
the event that the Administrative Agent wishes to retire as Administrative Agent or (ii) (in connection with the performance and exercise of its rights and obligations under the Loan Documents) as co-Administrative Agent, which appointment and (if
relevant) resignation shall be effective upon the Administrative Agent giving written notice thereof to the Lenders and the Borrowers. Any such appointment and/or resignation under this clause (b) shall not require the consent of any Lender
or Borrower. (c) Upon the acceptance of any appointment as Administrative Agent by a successor Administrative Agent or co-Administrative Agent pursuant to clauses (a) or (b) above, each such successor Administrative Agent shall succeed
to, and each such co-Administrative Agent shall accede to, and become vested with all the rights, powers, privileges and duties of the retiring or remaining Administrative Agent, and in the case of a retiring Administrative Agent, such
Administrative Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the retiring 

  

 101 








 
Administrative Agent shall continue to have the benefit of this Article X as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement and the other Loan Documents. 
  
 Section 10.7. Concerning the Collateral and the Collateral Documents. 
  
 (a) Each Lender and each Issuer agrees that any action taken by the Administrative Agent or the Requisite Lenders (or, where required by the express terms of this Agreement, a greater or different proportion or
combination of the Lenders) in accordance with the provisions of this Agreement or of the other Loan Documents, and the exercise by the Administrative Agent or the Requisite Lenders (or, where so required, such greater or different proportion or
combination) of the powers set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders, Issuers and other Secured Parties. Without limiting the generality
of the foregoing, the Administrative Agent shall have the sole and exclusive right and authority to (i) act as the disbursing and collecting agent for the Lenders and the Issuers with respect to all payments and collections arising in connection
herewith and with the Collateral Documents; (ii) execute and deliver the Senior Secured Note Intercreditor Agreement, the Senior Second Lien Note Intercreditor Agreement and each MCC Intercreditor Agreement and each Loan Document and accept delivery
of each such agreement delivered by Terra Industries or any of its Subsidiaries; (iii) manage, supervise and otherwise deal with the Collateral; (iv) take such action as is necessary or desirable to maintain the perfection and priority of the

Lender or such Issuer. 
  
 (c) Each of the Lenders and the Issuers
hereby directs, in accordance with the terms hereof, the Administrative Agent to release or instruct the Administrative Agent to release (or, in the case of clause (ii) below, release or subordinate) any Lien held by the Administrative Agent
for the benefit of the Lenders and the Issuers: 
  
 (i) against all of the Collateral, upon termination of the Revolving Credit Commitments and payment and satisfaction in full of all Loans, Reimbursement Obligations and all other Obligations which have matured and which the Administrative
Agent has been notified in writing are then due and payable (and, in respect of contingent Letter of Credit Obligations, with respect to which cash collateral has been deposited or a back-up letter of credit has been issued, in either case on terms
satisfactory to the Administrative Agent and the applicable Issuers); 
  
 (ii) against any assets that are subject to a Lien permitted by Section 8.2(d) or (e); 
  

 102 








 (iii) against any part of the Collateral sold or disposed of by a Loan Party if such sale
or disposition is permitted by this Agreement (or permitted pursuant to a waiver or consent of a transaction otherwise prohibited by this Agreement) or, if not pursuant to such sale or disposition, if such release is consented to by (A) all of the
Lenders, if the Collateral subject to such release is a substantial portion of all the Collateral, or (B) the Requisite Lenders, in all other cases; 
  
 (iv) against any cash collateral to the extent permitted under Section 7.12 or Section 2.9; and 
  
 (v) as of the Effective Date, against any collateral, but
only to the extent such collateral constitutes Senior Secured Note Collateral. 
  
 Each of the Lenders and the Issuers hereby directs the Administrative Agent to instruct the Administrative Agent to execute and deliver or file such termination and partial release statements and do such other things as are necessary to
release Liens to be released pursuant to this Section 10.7 promptly upon the effectiveness of any such release. 
  
 Section 10.8. Collateral Matters Relating to Related Obligations. The benefit of the Loan Documents and of the provisions of this
Agreement relating to the Collateral shall extend to and be available in respect of any Obligation which arises under any Hedging Contract or which is otherwise owed to Persons other than the Administrative Agent, the Arranger, the Lenders and the
Issuers (collectively, “Related Obligations”) solely on the condition and understanding, as among the Administrative Agent and all Secured Parties, that (i) the Related Obligations shall be entitled to the benefit of the Loan
Documents and the Collateral to the extent expressly set forth in this Agreement and the other Loan Documents and to such extent the Administrative Agent shall hold, and have the right and power to act with respect to, the Guaranty and the
Collateral on behalf of and as agent for the holders of the Related Obligations but the Administrative Agent is otherwise acting solely as agent for the Lenders and the Issuers and shall have no fiduciary duty, duty of loyalty, duty of care, duty of
disclosure or other obligation whatsoever to any holder of Related Obligations; (ii) all matters, acts and omissions relating in any manner to the Guaranty, the Collateral, or the omission, creation, perfection, priority, abandonment or release of
any Lien, shall be governed solely by the provisions of this Agreement, the Senior Secured Note Intercreditor Agreement and the other Loan Documents and no separate Lien, right, power or remedy shall arise or exist in favor of any Secured Party
under any separate instrument or agreement or in respect of any Related Obligation; and (iii) each Secured Party shall be bound by all actions taken or omitted, in accordance with the provisions of this Agreement, the Senior Secured Note
Intercreditor Agreement and the other Loan Documents, by the Administrative Agent and the Requisite Lenders (or, where required by the express terms of this Agreement, a greater or different proportion or combination of the Lenders), each of whom
shall be entitled to act at its sole discretion and exclusively in its own interest given its own Revolving Credit Commitments and its own interest in the Loans, Letter of Credit Obligations and other Obligations to it arising under this Agreement
or the other Loan Documents, without any duty or liability to any other Secured Party or as to any Related Obligation and without regard to whether any Related Obligation remains outstanding or is deprived of the benefit of the Collateral or becomes
unsecured or is otherwise affected or put in jeopardy thereby; and (iv) no holder of Related Obligations and no other Secured Party (except the Administrative Agent, the Arranger, the Lenders and the Issuers, to the extent set forth in this
Agreement) shall have any right to be notified of, or to direct, require 

  

 103 








 
or be heard with respect to, any action taken or omitted in respect of the Collateral or under this Agreement, the Senior Secured Note Intercreditor
Agreement or the Loan Documents; and (v) no holder of any Related Obligation shall exercise any right of setoff, banker’s lien or similar right except as expressly provided in Section 11.6.

the Person (except in its capacity as a Lender or Issuer) designated as the Arranger shall have no liability hereunder.

shall cause each Subsidiary Guarantor to agree, that the Administrative Agent may, but shall not be obligated to, make the Approved Electronic Communications available to the Lenders and Issuers by posting such Approved Electronic Communications on

 (b) Although the Approved Electronic Platform and its primary web portal are secured with generally-applicable security procedures and policies
implemented or modified by the Administrative Agent from time to time (including, as of the Effective Date, a dual firewall and a User ID/Password Authorization System) and the Approved Electronic Platform is secured through a single-user-per-deal
authorization method whereby each user may access the Approved Electronic Platform only on a deal-by-deal basis, each of the Lenders, the Issuers, Terra Industries, Terra Capital Holdings and the Borrowers acknowledges and agrees, and the Borrowers
shall cause each Subsidiary Guarantor to acknowledge and agree, that the distribution of material through an electronic medium is not necessarily secure and that there are confidentiality and other risks associated with such distribution. In
consideration for the convenience and other benefits afforded by such distribution and for the other consideration provided hereunder, the receipt and sufficiency of which is hereby acknowledged, each of the Lenders, the Issuers, Terra Industries,
Terra Capital Holdings and the Borrowers hereby approves, and the Borrowers shall cause each Subsidiary Guarantor to approve, distribution of the Approved Electronic Communications through the Approved Electronic Platform and understands and
assumes, and the Borrower shall cause each Subsidiary Guarantor to understand and assume, the risks of such distribution (except as otherwise set forth in Section 11.5(Limitation of Liability) hereunder). 
  
 (c) THE APPROVED ELECTRONIC
COMMUNICATIONS AND THE APPROVED ELECTRONIC PLATFORM ARE PROVIDED “AS IS”
AND “AS AVAILABLE”. NONE OF THE ADMINISTRATIVE AGENT OR ANY OF
ITS AFFILIATES OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
ADVISORS OR REPRESENTATIVES (THE “AGENT AFFILIATES”) WARRANT THE ACCURACY, ADEQUACY
OR COMPLETENESS OF THE APPROVED ELECTRONIC COMMUNICATIONS AND THE APPROVED
ELECTRONIC PLATFORM AND EACH EXPRESSLY DISCLAIMS LIABILITY FOR ERRORS OR OMISSIONS
IN THE APPROVED ELECTRONIC COMMUNICATIONS AND THE APPROVED ELECTRONIC PLATFORM
EXCEPT AS OTHERWISE SET FORTH IN SECTION 11.5 HEREUNDER. NO WARRANTY OF
ANY KIND, EXPRESS, IMPLIED OR STATUTORY (INCLUDING, WITHOUT LIMITATION, ANY WARRANTY
OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD
PARTY RIGHTS OR FREEDOM

FROM VIRUSES OR OTHER CODE DEFECTS) IS
MADE BY THE AGENT AFFILIATES IN CONNECTION WITH THE APPROVED ELECTRONIC

Terra Industries, Terra Capital Holdings and the Borrowers agree, and the Borrowers shall cause each Subsidiary Guarantor to agree, that the Administrative Agent may, but (except as may be required by applicable law) shall not be obligated to, store
the Approved Electronic Communications on the Approved Electronic Platform in accordance with the Administrative Agent’s generally-applicable document retention procedures and policies.

 MISCELLANEOUS 
  
 Section 11.1. Amendments, Waivers, Etc. 
  
 (a) No amendment or waiver of any provision of this Agreement or any other
Loan Document nor consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be in writing and signed by the Requisite Lenders, and then any such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given; provided, however, that no amendment, waiver or consent shall, unless in writing and signed by the relevant Lenders referred to below, in addition to the Requisite
Lenders, do any of the following: 
  
 (i) waive
any of the conditions specified in Section 3.1 (without the consent of all Lenders) or 3.2 (without the consent of all Lenders) except with respect to a condition based upon another provision hereof, the waiver of which requires only
the concurrence of the Requisite Lenders; 
  
 (ii) increase the Revolving Credit Commitment of any Lender or subject any Lender to any additional obligations (without the consent of each such Lender); 
  
 (iii) extend the scheduled final maturity of any Loan owing to any Lender, or waive, reduce or postpone any

such Lender (without the consent of such Lender); 
  
 (iv) reduce the principal amount of any Loan or Reimbursement Obligation owing to any Lender (other than by the payment or prepayment thereof) (without the consent of such Lender);

Obligations owing to any Lender or any fee payable hereunder to such Lender (without the consent of such Lender); 
  

 105 








 (vi) postpone any scheduled date fixed for payment of such interest or fees to such
Lender (without the consent of such Lender); 
  
 (vii) change the percentage of aggregate Revolving Credit Commitments or unpaid principal amount of the Loans or the number or percentage of Lenders which shall be required for the Lenders or any of them to take any action hereunder
(without the consent of each Lender);

 (ix) (without limiting Section 7.12) release a substantial portion of Collateral except as otherwise provided in Section
10.7(c) or release any Borrower or Guarantor from its obligations under this Agreement or its Guaranty, as applicable, except in connection with sale or other disposition permitted by this Agreement (or permitted pursuant to a waiver or consent

rights or duties of the Administrative Agent under this Agreement or the other Loan Documents. 
  
 (b) The Administrative Agent may, but shall have no obligation to, with the written concurrence of any Lender, execute amendments, modifications, waivers or consents on behalf of that Lender. Any waiver or consent
shall be effective only in the specific instance and for the specific purpose for which it was given. No notice to or demand on the Borrowers in any case shall entitle the Borrowers to any other or further notice or demand in similar or other
circumstances. 
  
 (c) In connection with any proposed amendment,
modification, waiver or termination (a “Proposed Change”) requiring the consent of all Lenders in addition to the Requisite Lenders, the consent of Requisite Lenders is obtained, but the consent of other Lenders whose consent is
required is not obtained (any such Lender whose consent is not obtained as described in this Section 11.1 being referred to as a “Non-Consenting Lender”), then, so long as the Lender that is acting as the Administrative Agent
is not a Non-Consenting Lender, at the Borrower’s request, the Administrative Agent or an Eligible Assignee that is acceptable to the Administrative Agent shall have the right with the Administrative Agent’s consent and in the
Administrative Agent’s sole discretion (but shall have no obligation) to purchase from such Non-Consenting Lender, and such Non-Consenting Lender agrees that it shall, upon the Administrative Agent’s request, sell and assign to the Lender
that is acting as the Administrative Agent or such Eligible Assignee, all of the Revolving Credit Commitments and Revolving Credit Outstandings of such Non-Consenting Lender for an amount equal to the principal balance of all Revolving Loans held by
the Non-Consenting Lender and all accrued interest and fees with respect thereto through the date of sale, such purchase and sale to be consummated pursuant to an executed Assignment and Acceptance.

 (a) Each Lender may sell, transfer, negotiate or assign to one or more
Eligible Assignees all or a portion of its rights and obligations hereunder (including all of its rights and obligations with respect to the Revolving Loans, the Swing Loans and the Letters of Credit); provided, however, that (i) if
any such assignment shall be of the assigning Lender’s Revolving Credit Outstandings and Revolving Credit Commitment, such assignment shall cover the same percentage of such Lender’s Revolving Credit Outstandings and Revolving Credit
Commitment and (ii) the aggregate amount being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event (if less than the Assignor’s entire
interest) be less than (in the case of (in aggregate) the Revolving Credit Outstandings (and/or the Revolving Credit Commitments)) $5,000,000 or an integral multiple of $1,000,000 in excess thereof, except, in either case, (A) with the consent of
Terra Capital and the Administrative Agent or (B) if such assignment is being made to a Lender or an Affiliate or Approved Fund of such Lender, and (iii) if such Eligible Assignee is not, prior to the date of such assignment, a Lender or an
Affiliate or Approved Fund of a Lender, such assignment shall be subject to the prior consent of the Administrative Agent and Terra Capital (which consent shall not be unreasonably withheld or delayed); provided, however, that,
notwithstanding any other provision of this Section 11.2, the consent of the Borrowers shall not be required for any assignment which occurs when any Event of Default shall have occurred and be continuing. 
  
 (b) The parties to each assignment shall execute and deliver to the
Administrative Agent, for its acceptance and recording, an Assignment and Acceptance, together with any Note (if the assigning Lender’s Loans are evidenced by a Note) subject to such assignment. Upon such execution, delivery, acceptance and
recording and the receipt by the Administrative Agent from the assignee of an assignment fee in the amount of $3,500 from and after the effective date specified in such Assignment and Acceptance, (i) the assignee thereunder shall become a party
hereto and, to the extent that rights and obligations under the Loan Documents have been assigned to such assignee pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender, and if such Lender were an Issuer, of such
Issuer hereunder and thereunder, and (ii) the assignor thereunder shall, to the extent that rights and obligations under this Agreement have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (except those which
survive the payment in full of the Obligations) and be released from its obligations to the extent corresponding thereto under the Loan Documents, other than those relating to events or circumstances occurring prior to such assignment (and, in the
case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under the Loan Documents, such Lender shall cease to be a party hereto). 
  
 (c) The Administrative Agent shall maintain at its address referred to in
Section 11.8 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recording of the names and addresses of the Lenders and the Revolving Credit Commitments of and principal amount of the Loans and
Letter of Credit Obligations owing to each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Loan Parties, the Administrative
Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender for all purposes of this Agreement. The Register shall be available for inspection by the 

  

 107 








 
Borrower, the Administrative Agent or any Lender at any reasonable time and from time to time upon reasonable prior notice. 
  
 (d) Upon its receipt of an Assignment and Acceptance executed by an assigning
Lender and an assignee, the Administrative Agent shall, if such Assignment and Acceptance has been completed, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice
thereof to the Borrowers. Within five Business Days after its receipt of such notice, the Borrowers, at their own expense, shall, if requested by such assignee, execute and deliver to the Administrative Agent, new Notes to the order of such assignee
in an amount equal to the Revolving Credit Commitments assumed by it pursuant to such Assignment and Acceptance and, if the assigning Lender has surrendered any Note for exchange in connection with the assignment and has retained Revolving Credit
Commitments hereunder, new Notes to the order of the assigning Lender in an amount equal to the Revolving Credit Commitments retained by it hereunder. Such new Notes shall be dated the same date as the surrendered Notes and be in substantially the
form of Exhibit B. 
  
 (e) In addition to the other
assignment rights provided in this Section 11.2, each Lender may assign, as collateral or otherwise, any of its rights under this Agreement (including rights to payments of principal or interest on the Loans) to (i) any Federal Reserve Bank
pursuant to Regulation A of the Federal Reserve Board without notice to or consent of the Borrowers or the Administrative Agent and (ii) any trustee for the benefit of the holders of such Lender’s Securities; provided, however,
that no such assignment shall release the assigning Lender from any of its obligations hereunder. 
  
 (f) Each Lender may sell participations to one or more Persons in or to all or a portion of its rights and obligations under the Loan Documents (including
all its rights and obligations with respect to the Revolving Loans and Letters of Credit). The terms of such participation shall not, in any event, require the participant’s consent to any amendments, waivers or other modifications of any
provision of any Loan Documents, the consent to any departure by any Loan Party therefrom, or to the exercising or refraining from exercising any powers or rights which such Lender may have under or in respect of the Loan Documents (including the
right to enforce the obligations of the Loan Parties), except if any such amendment, waiver or other modification or consent would (i) reduce the amount, or postpone any date fixed for, any amount (whether of principal, interest or fees) payable to
such participant under the Loan Documents, to which such participant would otherwise be entitled under such participation or (ii) result in the release of all or substantially all of the Collateral other than in accordance with Section
10.7(c). In the event of the sale of any participation by any Lender, (A) such Lender’s obligations under the Loan Documents shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties for the performance of
such obligations, (C) such Lender shall remain the holder of such Obligations for all purposes of this Agreement, and (D) 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. Each participant shall be entitled to the benefits of Sections 2.14(c), 2.14(e), 2.15 and 2.16 as if it were a Lender; provided,
however, that anything herein to the contrary notwithstanding, the Borrower shall not, at any time, be obligated to pay to any participant of any interest of any Lender, under Section 2.14(c), 2.14(e), 2.15 or 2.16,
any sum in excess of the sum which the Borrowers would have been obligated to pay to such Lender in respect of such interest had such participation not been sold. 
  

 108 








 (g) Any Issuer may at any time assign its rights and obligations hereunder to any other Lender by an
instrument in form and substance satisfactory to the Borrowers, the Administrative Agent, such Issuer and such Lender. If any Issuer ceases to be a Lender hereunder by virtue of any assignment made pursuant to this Section 11.2, then, as of
the effective date of such cessation, such Issuer’s obligations to issue Letters of Credit pursuant to Section 2.4 shall terminate and such Issuer shall be an Issuer hereunder only with respect to outstanding Letters of Credit issued
prior to such date. 
  
 Section 11.3. Costs and
Expenses. 
  
 (a) Each Borrower agrees upon demand to pay,
or reimburse the Administrative Agent for, all of the Administrative Agent’s reasonable internal and external audit, legal, appraisal, valuation, filing, document duplication and reproduction and investigation expenses and for all other
reasonable and documented out-of-pocket costs and expenses of every type and nature (including, without limitation, the reasonable and documented fees, expenses and disbursements of the Administrative Agent’s New York and English counsel, Weil,
Gotshal & Manges LLP and additional local legal counsel, auditors, accountants, appraisers, printers, insurance and environmental advisers, and other consultants and agents) reasonably incurred by the Administrative Agent in connection with (i)
the Administrative Agent’s audit and investigation of Terra Industries and its Subsidiaries in connection with the preparation, negotiation and execution of the Loan Documents and the Administrative Agent’s periodic audits of Terra
Industries and its Subsidiaries, as the case may be; (ii) the preparation, negotiation, execution and interpretation of this Agreement (including, without limitation, the satisfaction or attempted satisfaction of any of the conditions set forth in
Article III), the Loan Documents and any proposal letter or commitment letter issued in connection therewith and the making of the Loans hereunder; (iii) the creation, perfection or protection of the Liens under the Loan Documents (including,
without limitation, any reasonable and documented fees and expenses for local counsel in various jurisdictions); (iv) the ongoing administration of this Agreement and the Loans, including consultation with attorneys in connection therewith and with
respect to the Administrative Agent’s rights and responsibilities hereunder and under the other Loan Documents; (v) the protection, collection or enforcement of any of the Obligations or the enforcement of any of the Loan Documents; (vi) the
commencement, defense or intervention in any court proceeding relating in any way to the Obligations, any Loan Party, any of Terra Industries’ Subsidiaries, this Agreement or any of the other Loan Documents; (vii) the response to, and
preparation for, any subpoena or request for document production with which the Administrative Agent is served or deposition or other proceeding in which the Administrative Agent is called to testify, in each case, relating in any way to the
Obligations, any Loan Party, any of Terra Industries’ Subsidiaries, this Agreement or any of the other Loan Documents; and (viii) any amendments, consents, waivers, assignments, restatements, or supplements to any of the Loan Documents and the
preparation, negotiation, and execution of the same. 
  
 (b) Each
Borrower further agrees to pay or reimburse the Administrative Agent and each of the Lenders and Issuers upon demand for all reasonable and documented out-of-pocket costs and expenses, including, without limitation, reasonable attorneys’ fees
(including allocated costs of internal counsel and costs of settlement), incurred by the Administrative Agent, such Lenders or Issuers (i) in enforcing any Loan Document or Obligation or any security therefor or exercising or enforcing any other
right or remedy available by reason of an Event of Default; (ii) in connection with any refinancing or restructuring of the credit arrangements provided hereunder in the nature of a “work-out” or in any insolvency or bankruptcy
proceeding; 

  

 109 








 
(iii) in commencing, defending or intervening in any litigation or in filing a petition, complaint, answer, motion or other pleadings in any legal proceeding
relating to the Obligations, any Loan Party, any of Terra Industries’ Subsidiaries and related to or arising out of the transactions contemplated hereby or by any of the other Loan Documents; and (iv) in taking any other action in or with
respect to any suit or proceeding (bankruptcy or otherwise) described in clauses (i) through (iii) above. 
  
 Section 11.4. Indemnities. 
  
 (a) Each Borrower agrees to indemnify and hold harmless the Administrative Agent, each Lender and each Issuer and each of their respective Affiliates, and
each of the directors, officers, employees, agents, representatives, attorneys, consultants and advisors of or to any of the foregoing (including those retained in connection with the satisfaction or attempted satisfaction of any of the conditions
set forth in Article III) (each such Person being an “Indemnitee”) from and against any and all claims, damages, liabilities, obligations, losses, penalties, actions, judgments, suits, costs, disbursements and expenses of any
kind or nature (including reasonable and documented fees and disbursements of counsel to any such Indemnitee, but excluding taxes (other than those covenanted to be paid by the Borrowers under this Agreement) imposed on or measured by the
Indemnitee’s net income and franchise taxes, imposed on it, by the jurisdiction (or any political subdivision thereof) under the laws of which such Indemnitee is organized or in which its principal office or Applicable Lending Office is
located) which may be imposed on, incurred by or asserted against any such Indemnitee in connection with or arising out of any investigation, litigation or proceeding, whether or not any such Indemnitee is a party thereto, whether direct, indirect,
or consequential and whether based on any federal, state or local law or other statutory regulation, securities or commercial law or regulation, or under common law or in equity, or in contract, tort or otherwise, relating to or arising out of this
Agreement, any other Loan Document, any Obligation, any Letter of Credit, or any act, event or transaction related or attendant to any thereof, or the use or intended use of the proceeds of the Loans or Letters of Credit or in connection with any
investigation of any potential matter covered hereby (collectively, the “Indemnified Matters”). Without limiting the foregoing, Indemnified Matters include (i) all Environmental Liabilities and Costs arising from or connected with
the past, present or future operations of Terra Industries or any of its Subsidiaries involving any property subject to a Collateral Document, or damage to real or personal property or natural resources or harm or injury alleged to have resulted
from any Release of Contaminants on, upon or into such property or any contiguous real estate; (ii) any costs or liabilities incurred in connection with any Remedial Action concerning Terra Industries or any of its Subsidiaries; (iii) any costs or
liabilities incurred in connection with any Environmental Lien in respect of any assets or properties of Terra Industries and its Subsidiaries; (iv) any costs or liabilities incurred in connection with any other matter (concerning Terra Industries
or any of its Subsidiaries) under any Environmental Law, including CERCLA and applicable state property transfer laws, whether, with respect to any of such matters, such Indemnitee is a mortgagee pursuant to any leasehold mortgage, a mortgagee in
possession, the successor in interest to Terra Industries or any of its Subsidiaries, or the owner, lessee or operator of any property of Terra Industries or any of its Subsidiaries by virtue of foreclosure, except, with respect to those matters
referred to in clauses (i), (ii), (iii) and (iv) above, to the extent incurred following (A) foreclosure by the Administrative Agent, any Lender or any Issuer, or the Administrative Agent, any Lender or any Issuer having
become the successor in interest to Terra Industries or any of its Subsidiaries, and (B) attributable solely to acts of the Administrative Agent, such Lender or such Issuer or any agent on behalf of the Administrative Agent, such Lender or such
Issuer; provided, however, that 

  

 110 








 
the Borrowers shall not have any obligation under this Section 11.4 to an Indemnitee with respect to any Indemnified Matter caused by or resulting
from the gross negligence or willful misconduct of that Indemnitee, as determined by a court of competent jurisdiction in a final non-appealable judgment or order. 
  
 (b) Each Borrower shall indemnify the Administrative Agent, the Lenders and each Issuer for, and hold the Administrative
Agent, the Lenders and each Issuer harmless from and against, any and all claims for brokerage commissions, fees and other compensation made against the Administrative Agent, the Lenders and the Issuers for any broker, finder or consultant with
respect to any agreement, arrangement or understanding made by or on behalf of any Loan Party or any of its Subsidiaries in connection with the transactions contemplated by this Agreement. 
  
 (c) Each Borrower agrees that any indemnification or other protection
provided to any Indemnitee pursuant to this Agreement (including pursuant to this Section 11.4) or any other Loan Document shall (i) survive payment in full of the Obligations and (ii) inure to the benefit of any Person who was at any time an
Indemnitee under this Agreement or any other Loan Document. 
  
 Section 11.5. Limitation of Liability. 
  
 (a) Each Borrower agrees that no Indemnitee shall (except for breach by such Indemnitee of its obligations under this Agreement and the other Loan Documents) have any liability (whether direct or indirect, in contract, tort or otherwise) to
any Loan Party or any of their respective Subsidiaries or any of their respective equity holders or creditors for or in connection with the transactions contemplated hereby and in the other Loan Documents and the MCC Acquisition Documents, except to
the extent such liability is found in a final judgment by a court of competent jurisdiction to have resulted from such Indemnitee’s gross negligence or willful misconduct. In no event, however, shall any Indemnitee be liable on any
theory of liability for any special, indirect, consequential or punitive damages and each of Terra Industries and each Borrower hereby waives, releases and agrees (for itself and on behalf of its Subsidiaries) not to sue upon any such claim for any
special indirect, consequential or punitive damages, whether or not accrued and whether or not known or suspected to exist in its favor. 
  
 (b) IN NO EVENT SHALL ANY AGENT AFFILIATE
HAVE ANY LIABILITY TO ANY LOAN PARTY, LENDER, ISSUER OR ANY OTHER
PERSON FOR DAMAGES OF ANY KIND, INCLUDING DIRECT OR INDIRECT, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT OR
CONTRACT OR OTHERWISE) ARISING OUT OF ANY LOAN PARTY OR ANY AGENT
AFFILIATE’S TRANSMISSION OF APPROVED ELECTRONIC COMMUNICATIONS THROUGH THE INTERNET
OR ANY USE OF THE APPROVED ELECTRONIC PLATFORM, EXCEPT TO THE EXTENT
SUCH LIABILITY OF ANY AGENT AFFILIATE IS FOUND IN A FINAL
NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE
RESULTED FROM SUCH AGENT AFFILIATE’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

  
 Section 11.6. Right of Set-off. Upon the
occurrence and during the continuance of any Event of Default each Lender and each Affiliate of a Lender 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 

  

 111 








 
held and other indebtedness at any time owing by such Lender or its Affiliates to or for the credit or the account of any Borrower against any and all of the
Obligations now or hereafter existing 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. Each Lender agrees promptly to notify the applicable Borrower
after any such set-off and application made by such Lender or its Affiliates; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender under this
Section 11.6 are in addition to the other rights and remedies (including other rights of set-off) which such Lender may have. 
  
 Section 11.7. Sharing of Payments, Etc. 
  
 (a) If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off or otherwise) on account of the
Revolving Loans made by it (other than pursuant to Section 2.14, 2.15 or 2.16) in excess of its Ratable Portion under the Revolving Credit Facility, in respect of payments obtained by the Lenders, on account of such Obligations,
such Lender (a “Purchasing Lender”) shall forthwith purchase from the other Lenders (each, a “Selling Lender”) such participations in their Loans or other Obligations as shall be necessary to cause such Purchasing
Lender to share the excess payment ratably with each of them. 
  
 (b) If all or any portion of any payment received by a Purchasing Lender is thereafter recovered from such Purchasing Lender, such purchase from each Selling Lender shall be rescinded and such Selling Lender shall repay to the Purchasing
Lender the purchase price to the extent of such recovery together with an amount equal to such Selling Lender’s ratable share (according to the proportion of (i) the amount of such Selling Lender’s required repayment to (ii) the total
amount so recovered from the Purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. 
  
 (c) Each Borrower agrees that any Purchasing Lender so purchasing a participation from a Selling Lender pursuant to this
Section 11.7 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount
of such participation.

any other Loan Document providing for the delivery of, any Approved Electronic Communication by any other means, the Loan Parties shall deliver all Approved Electronic Communications to the Administrative Agent by properly transmitting such Approved
Electronic Communications electronically (in a format reasonably acceptable to the Administrative Agent) to oploanswebadmin@citigroup.com or such other electronic mail address (or similar means of electronic delivery) as the Administrative Agent may
notify the Borrower. Nothing in this clause (c) shall prejudice the right of the Administrative 

  

 114 








 
Agent or any Lender or Issuer to deliver any Approved Electronic Communication to any Loan Party in any manner authorized in this Agreement. 
  
 Section 11.9. No Waiver; Remedies. No failure on the
part of any Lender, Issuer or the Administrative Agent to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise
thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law. 
  
 Section 11.10. Binding Effect. This Agreement shall become effective on the Effective Date and thereafter this Agreement shall be
binding upon and inure to the benefit of the Borrowers, the Administrative Agent and each Lender and their respective successors and assigns, except that the Borrowers shall not have the right to assign its rights hereunder or any interest herein
without the prior written consent of the Lenders. On the Effective Date, the Existing Credit Agreement shall be amended and restated in its entirety by this Agreement and the Existing Credit Agreement shall thereafter be of no further force and
effect except as to evidence the incurrence by the Borrowers’ of the Obligations thereunder, as to evidence the representations and warranties made by the Borrowers prior to the Effective Date and as to evidence any failure to comply with the
covenants contained in such Existing Credit Agreement occurring prior to the Effective Date. The terms and conditions of this Agreement and the Administrative Agent’s, the Lenders’ and the Issuers’ rights and remedies under this
Agreement and the other Loan Documents, shall apply to all of the Obligations incurred under the Existing Credit Agreement and the Notes issued as of April 7, 2000. It is expressly understood and agreed by the parties hereto that this Agreement is
in no way intended to constitute a novation of the obligations and liabilities existing under the Existing Credit Agreement or evidence payment of all or any of such obligations and liabilities. Other than with respect to Liens on the assets of the
Loan Parties constituting Senior Secured Note Collateral, each Borrower party to the Existing Credit Agreement reaffirms the Liens granted to the Administrative Agent for the benefit of the Lenders and the Issuers pursuant to each of the Loan
Documents executed by such Borrower, which Liens shall continue in full force and effect during the term of this Agreement and any renewals thereof and shall continue to secure the Obligations identified in such Loan Documents. All references to the
Existing Credit Agreement (or to any amendment or any amendment and restatement thereof) in the Loan Documents shall be deemed to refer to this Agreement. 
  
 Section 11.11. Governing Law. This Agreement and the rights and obligations of the parties hereto shall be governed by, and construed
and interpreted in accordance with, the law of the State of New York. 
  
 Section 11.12. Submission to Jurisdiction; Service of Process. 
  
 (a) Any legal action or proceeding with respect to this Agreement or any other Loan Document may 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, and, by execution and delivery of this Agreement, each Borrower hereby accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of the aforesaid courts. The parties hereto hereby irrevocably waive any
objection, including any objection to the laying of venue or based on the grounds of forum non conveniens, which any of them may now or hereafter have to the bringing of any such action or proceeding in such respective
jurisdictions. 
  

 115 








 (b) Terra UK hereby irrevocably designates, appoints and empowers Terra Industries (the “Process
Agent”), in the case of any suit, action or proceeding brought in the United States of America as its designee, appointee and agent to receive, accept and acknowledge for and on its behalf, and in respect of its property, service of any and
all legal process, summons, notices and documents that may be served in any action or proceeding arising out of or in connection with this Agreement or any Loan Document. Such service may be made by mailing (by registered or certified mail, postage
prepaid) or delivering a copy of such process to Terra UK in care of the Process Agent at the Process Agent’s above address, and Terra UK hereby irrevocably authorizes and directs the Process Agent to accept such service on its behalf. As an
alternative method of service, Terra UK irrevocably consents to the service of any and all process in any such action or proceeding by the mailing (by registered or certified mail, postage prepaid) of copies of such process to the Process Agent or
Terra UK at its address specified in Section 11.8. The Borrower agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Terra Capital hereby irrevocably consents to the service of any and all legal process, summons, notices and documents in any suit, action or proceeding brought in the United States of America arising out of or in connection with
this Agreement or any of the other Loan Documents by the mailing (by registered or certified mail, postage prepaid) or delivering of a copy of such process to such Borrower at its address specified in Section 11.8. Each such Borrower agrees
that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. 
  
 (c) Nothing contained in this Section 11.12 shall affect the right of the Administrative Agent or any Lender to serve
process in any other manner permitted by law or commence legal proceedings or otherwise proceed against the Borrower or any other Loan Party in any other jurisdiction. 
  
 (d) If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder in Dollars into
another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase Dollars
with such other currency at the spot rate of exchange quoted by the Administrative Agent at 11:00 a.m. (New York time) on the Business Day preceding that on which final judgment is given, for the purchase of Dollars, for delivery two Business Days
thereafter. 
  
 Section 11.13. Waiver of Jury Trial.
EACH OF THE ADMINISTRATIVE AGENT, THE LENDERS, THE ISSUERS AND THE
BORROWER IRREVOCABLY WAIVES TRIAL BY JURY IN ANY ACTION OR PROCEEDING
WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT. 
  
 Section 11.14. No Immunity. To the extent that Terra UK
may be or become entitled, in any jurisdiction in which judicial proceedings may at any time be commenced with respect to this Agreement or any other Loan Document, to claim for itself or its properties or revenues any immunity from suit, court
jurisdiction, attachment prior to judgment, attachment in aid of execution of a judgment, execution of a judgment or from any other legal process or remedy relating to its respective obligations under this Agreement or any other Loan Document, and
to the extent that in any such jurisdiction there may be attributed such an immunity (whether 

  

 116 








 
or not claimed), Terra UK hereby irrevocably agrees not to claim and hereby irrevocably waives such immunity to the fullest extent permitted by the laws of
such jurisdiction. 
  
 Section 11.15. Judgment
Currency. This is an international loan transaction in which the specification of Dollars is of the essence, and Dollars shall in each instance be the currency of account and payment in all instances. A payment obligation in Dollars
hereunder shall not be discharged by an amount paid in another currency (the “Other Currency”), whether pursuant to any judgment expressed in or converted into any Other Currency or in another place except to the extent that such
tender or recovery results in the effective receipt by the Lenders of the full amount of Dollars payable to the Administrative Agent and the Lenders under this Agreement. If for the purpose of obtaining judgment in any court it is necessary to
convert a sum due hereunder in Dollars into the Other Currency, the rate of exchange that shall be applied shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase U.S. Dollars in New York, New York
with the Other Currency on the Business Day next preceding the day on which such judgment is rendered. The obligation of Terra UK in respect of any such sum due from it to the Administrative Agent and the Lenders hereunder or under any other Loan
Document shall, notwithstanding the rate of exchange actually applied in rendering such judgment, be discharged only to the extent that on the Business Day following receipt by the Administrative Agent or any Lender of any sum adjudged to be due
hereunder in the Other Currency the Administrative Agent may in accordance with normal banking procedures purchase Dollars with the amount of the judgment currency so adjudged to be due; and the Borrower hereby, as a separate obligation and
notwithstanding any such judgment, agrees to indemnify the Administrative Agent and the Lenders against, and to pay the Administrative Agent and Lenders on demand, in Dollars, the amount (if any) by which the sum originally due to the Administrative
Agent and the Lenders in Dollars hereunder exceeds the amount of the Other Currency so purchased. 
  
 Section 11.16. Marshaling; Payments Set Aside. None of the Administrative Agent, any Lender or any Issuer shall be under any
obligation to marshal any assets in favor of the Borrowers or any other party or any other Lender which does not have an equivalent interest in the Revolving Credit Facility or against or in payment of any or all of the Obligations. To the extent
that the Borrowers make a payment or payments to the Administrative Agent, the Lenders or the Issuers or any of such Persons receives payment from the proceeds of the Collateral or exercise their rights of setoff, and such payment or payments or the
proceeds of such enforcement or setoff or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, receiver or any other party, then to the extent of such recovery,
the obligation or part thereof originally intended to be satisfied, and all Liens, right and remedies therefor, shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not
occurred. 
  
 Section 11.17. Section Titles.
The Section titles contained in this Agreement are and shall be without substantive meaning or content of any kind whatsoever and are not a part of the agreement between the parties hereto. 
  
 Section 11.18. Execution in Counterparts. This Agreement
may be executed in any number of counterparts and by different parties in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Signature
pages may be detached from multiple separate 

  

 117 








 
counterparts and attached to a single counterpart so that all signature pages are attached to the same document. 
  
 Section 11.19. Entire Agreement. This Agreement,
together with all of the other Loan Documents and all certificates and documents delivered hereunder or thereunder, embodies the entire agreement of the parties and supersedes all prior agreements and understandings relating to the subject matter
hereof. 
  
 Section 11.20. Confidentiality.
Each Lender and the Administrative Agent (a) agrees to keep information obtained by it pursuant hereto and the other Loan Documents confidential in accordance with such Lender’s or the Administrative Agent’s, as the case may be, customary
practices and (b) agrees that it will only use such information in connection with the transactions contemplated by this Agreement and not disclose any of such information other than (i) to such Lender’s or the Administrative Agent’s, as
the case may be, employees, representatives and agents who are or are expected to be involved in the evaluation of such information in connection with the transactions contemplated by this Agreement and who are advised of the confidential nature of
such information, (ii) to the extent such information presently is or hereafter becomes available to such Lender or the Administrative Agent, as the case may be, on a non-confidential basis from a source other than the Borrowers, (iii) to the extent
disclosure is required by law, regulation or judicial order or requested or required by bank regulators or auditors, or (iv) to assignees or participants or potential assignees or participants who agree to be bound by the provisions of this
Section 11.20. 
  
 Section 11.21. Refund of Tax
Credits. If: 
  
 (a) Terra UK makes a payment under
Section 2.16(a) (a “Tax Payment”) in respect of a payment to a Lender or the Administrative Agent under this agreement; and 
  
 (b) that Lender or the Administrative Agent determines in its discretion that it has obtained a refund of tax or obtained and used a credit against tax on
its overall net income (a “Tax Credit”) which that Lender or as appropriate the Administrative Agent in its discretion is able to identify as attributable to that Tax Payment, 
  
 then if it can do so without any adverse consequences for that Lender or if applicable the
Administrative Agent, that Lender or if applicable the Administrative Agent shall reimburse Terra UK such amount as that Lender or if applicable the Administrative Agent determines to be such proportion of that Tax Credit as will leave that Lender
or if applicable the Administrative Agent (after that reimbursement) in no better or worse position in respect of its overall tax liabilities than it would have been in if no Tax Payment had been required. A Lender or where applicable the
Administrative Agent shall have an absolute discretion as to whether to claim any Tax Credit (and, if it does claim, the extent order and manner in which it does so). Neither the Lender nor the Administrative Agent should be obliged to disclose any
of its tax affairs or computations to Terra UK or any other Loan Party.
