Within the foregoing limits, the Borrower may borrow, prepay and reborrow Revolving Loans in accordance with the provisions hereof. The principal amount outstanding of all Revolving Loans shall mature and be due and payable, together with all
accrued and unpaid interest thereon, on the Termination Date.

 Section 2.02 Making the Loans. 
  
 (a) Each Borrowing shall be made on written notice given by the Borrower to the Agent not later than (i) 12:00 Noon (New
York City time) on the date of the Borrowing in the case of a Borrowing consisting of Base Rate Loans and (ii) 12:00 Noon (New York City time) on the third Business Day prior to the date of the Borrowing in the case of a Borrowing consisting of
Eurodollar Rate Loans. Each such notice of a Borrowing (a “Notice of Borrowing”) shall be in the form of Exhibit 2.02 and shall specify (A) the date of such Borrowing, (B) the number of Borrowings and the Type, Class and aggregate
principal amount of Loans comprising each Borrowing and (C) in the case of a Borrowing comprised of Eurodollar Rate Loans, the initial Interest Period for each such Loan. Each Notice of Borrowing shall be irrevocable and binding on the Borrower. The
Agent shall promptly deliver notice of each Borrowing to each Lender. 
  
 (b) Each Lender shall, before (i) 2:00 P.M. (New York City time) on the date of a Borrowing consisting of Base Rate Loans and (ii) 12:00 Noon (New York City time) on the date of a Borrowing consisting of Eurodollar Rate Loans, make
available for the account of its applicable Lending Office to the Agent at the Agent’s Office, in immediately available funds, such Lender’s Revolving Share or Term Share, as applicable, of such Borrowing. After the Agent’s receipt of
such funds and, upon fulfillment of the applicable conditions set forth in Article IV, the Agent shall make such funds available to the Borrower’s account at the Agent’s Office or as otherwise designated in the Notice of Borrowing. In the
case of any Borrowing consisting of Base Rate Loans, the Agent will not be required to make funds so available until 3:00 P.M. (New York City time) on the date of such Borrowing. 
  
 (c) Unless the Agent has received written notice from a Lender prior to (i) 1:00 P.M. (New York City time) on the date of
any Borrowing consisting of Base Rate Loans and (ii) 11:00 A.M. (New York City time) on the date of any Borrowing consisting of Eurodollar Rate Loans that such Lender will not make available to the Agent such Lender’s Revolving Share or Term
Share, as applicable, of such Borrowing, the Agent may assume such Lender has made such portion available to the Agent on the date of such Borrowing in accordance with Section 2.02(b) and the Agent in its sole discretion may, in reliance on such
assumption, make available to the Borrower on such date a corresponding amount on behalf of such Lender. If and to the extent that such Lender shall not have so made its Revolving Share or Term Share, as applicable, of a Borrowing available to the
Agent, such Lender and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such
amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Loans comprising such Borrowing, and (ii) in the case of such Lender, the Federal Funds Rate until (and including) the third Business Day
after demand is made and thereafter at the Base Rate. If such Lender shall repay to the 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
Borrower shall repay to the Agent such corresponding amount, the Borrower shall have no liability with respect to losses, costs or expenses otherwise compensable under Section 3.04 in connection therewith. 
  
 (d) The obligations of the Lenders to make Loans to the Borrower pursuant to
this Agreement are several and not joint or joint and several, and the failure of any Lender to make 

  

 -28- 

 
the Loan to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Loan on the date of
such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Loan to be made by such other Lender on the date of any Borrowing. 
  
 Section 2.03 Letters of Credit. 
  
 (a) Each Issuer agrees, on the terms and conditions hereinafter set forth, to issue, extend and renew Letters of Credit from
time to time on any Business Day during the period from the date of this Agreement to but not including the tenth (10th) day prior to the Termination Date, in such form as may be requested by the Borrower and agreed to by such Issuer, which agreement shall not be unreasonably withheld; provided, however, the Issuers shall have no
obligation to, and shall not, issue any Letter of Credit in excess of the Available Revolving Credit. No Lender other than the Issuers has any obligation to issue any Letter of Credit. On the Closing Date, the Existing Letters of Credit shall
automatically and without further action on the part of the Borrower become Letters of Credit under this Agreement, and such Letters of Credit shall be deemed to have been issued by Credit Suisse First Boston, as the Issuer, on the Closing Date for
purposes of this Agreement and shall be subject to all the terms, provisions, and requirements of this Agreement relating to Letters of Credit issued hereunder. 
  

(b) Each Letter of Credit shall be denominated in Dollars and in no event shall the expiry date of any Letter of Credit extend beyond five (5) Business
Days prior to the Termination Date. Any extension of any expiry date or renewal of a Letter of Credit shall constitute an “issuance” of such Letter of Credit for all purposes of this Agreement. 
  
 (c) In addition to the terms and conditions of this Agreement, each Letter of
Credit shall be issued pursuant to and the Issuer of each such Letter of Credit shall be entitled to the benefits of the applicable Letter of Credit Reimbursement Agreement. 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 control to the extent of any such conflict. 
  
 (d) Each issuance of a Letter of Credit other than the deemed issuance described in the last sentence of Section 2.03(a) shall be made on notice given by
the Borrower to the Agent and the Issuer of such Letter of Credit not later than 12:00 Noon (New York City time) three (3) Business Days prior to the date of the proposed issuance of such Letter of Credit. Each such notice (a “Letter of
Credit Request”) shall be in the form of Exhibit 2.03(d), shall be irrevocable and shall specify (i) the stated amount of the Letter of Credit, (ii) the date of issuance of such Letter of Credit, (iii) the expiry date of such Letter of
Credit, (iv) the beneficiary of such Letter of Credit and (v) such other terms reasonably satisfactory to the Issuer of such Letter of Credit as to enable such Issuer to issue such Letter of Credit consistent with the reasonable requirements of the
beneficiary thereof. The Agent shall promptly deliver notice of each issuance of a Letter of Credit to each Lender; if a Lender requests in writing a copy of the Letter of Credit Request corresponding to such issuance, then the Agent shall provide
such Lender with a copy of such Letter of Credit Request. On the Business Day prior to the date on which such Letter of Credit is to be issued, upon the request of the Issuer of such Letter of Credit, the Agent shall confirm to such Issuer that the
applicable conditions in Article IV have been satisfied as of such date. 
  

 -29- 

 (e) Subject to the terms and conditions of this Section 2.03 and satisfaction of the conditions set forth
in Article IV, the Issuer of such Letter of Credit shall on the date requested in the Letter of Credit Request issue a Letter of Credit for the account of the Borrower in accordance with such Issuer’s usual and customary business practices and
confirm to the Agent and each Lender that such Letter of Credit has been issued. Each Lender and the Borrower hereby acknowledge that each Letter of Credit issued by an Issuer pursuant to this Agreement is issued by such Issuer on behalf of all
Lenders at the time of such issuance. Immediately upon the issuance of a Letter of Credit, including the deemed issuance described in the last sentence of Section 2.03(a), the applicable Issuer shall be deemed to have sold and transferred to each
such Lender, and each such Lender shall be deemed to have irrevocably and unconditionally purchased and received from such Issuer, without recourse or warranty, an undivided interest and participation, to the extent of such Lender’s Revolving
Share thereof, in such Letter of Credit and the obligations of the Borrower with respect thereto and any security therefor and any guaranty pertaining thereto at any time existing. 
  
 (f) Each Issuer shall promptly notify (i) the Agent, who will promptly notify each Lender, of such Issuer’s receipt of
a draw request under any Letter of Credit, stating the amount of each Lender’s Revolving Share of such draw request and the date on which such request will be honored and (ii) the Borrower of the amount of such draw request and the date on
which such request will be honored. Any failure of such Issuer to give or any delay in such Issuer’s giving any such notice shall not release or diminish the obligations of the Borrower, the Agent or the Lenders in respect thereof. In
determining whether to pay under any Letter of Credit, such Issuer shall have no obligation to the Agent or to any Lender other than to confirm that any documents required to be delivered under such Letter of Credit have been delivered and that they
appear to comply on their face with the requirements of such Letter of Credit. IN THE ABSENCE OF GROSS NEGLIGENCE OR WILLFUL MISCONDUCT ON THE PART OF SUCH ISSUER, SUCH ISSUER SHALL HAVE NO LIABILITY TO THE AGENT OR ANY LENDER FOR ANY ACTION TAKEN
OR OMITTED TO BE TAKEN BY IT UNDER OR IN CONNECTION WITH ANY LETTER OF CREDIT, INCLUDING ANY SUCH ACTION NEGLIGENTLY TAKEN OR NEGLIGENTLY OMITTED TO BE TAKEN BY IT. 
  
 (g) The Borrower shall pay (either from the proceeds of a Borrowing or otherwise) to each Issuer on demand at such
Issuer’s Office in Dollars in immediately available funds the amount of all Reimbursement Obligations owing to such Issuer under any Letter of Credit, together with interest thereon at a rate of interest equal to the Base Rate in effect from
time to time for each day from, and including, the date of payment by such Issuer of the applicable draw request under such Letter of Credit to, but excluding, the date of payment in full to such Issuer of such Reimbursement Obligations,
irrespective of any claim, setoff, defense or other right which the Borrower may have at any time against such Issuer or any other Person. In the event that an Issuer makes any payment under any Letter of Credit and the Borrower shall not have
repaid such amount to such Issuer when due, such Issuer shall promptly notify the Agent, which shall promptly notify each Lender of such failure, and, subject to Section 2.03(e), each Lender shall promptly and unconditionally pay to the Agent for
the account of such Issuer the amount of such Lender’s Revolving Share of such payment, in Dollars in immediately available funds on the Business Day the Agent so notifies such Lender if such notice is given prior to 12:00 Noon (New York City
time) or, if such notice is given after 12:00 Noon (New York City time), such Lender shall make its Revolving Share of such payment available to the Agent prior to 12:00 Noon 

  

 -30- 

 
(New York City time) on the next succeeding Business Day. The Agent shall promptly pay to such Issuer such amounts received by it from each Lender. All such
payments by such Lenders shall constitute Base Rate Loans made by such Lenders to the Borrower pursuant to Section 2.01 (irrespective of the satisfaction of the conditions in Article IV, which are irrevocably waived) and the Reimbursement
Obligations with respect to which such Loans were made shall thereupon be paid to the extent of such payments; provided, however, if pursuant to any Governmental Requirement, such payment made by any Lender is not permitted to be made
as a Loan, such Reimbursement Obligation shall be reinstated and not so reduced by the amount of such payment and such Lender’s participations therein pursuant to Section 2.03(e) similarly shall be reinstated to such amount. 
  
 (h) If and to the extent any Lender shall not make such Lender’s
Revolving Share of any Reimbursement Obligations available to the Agent for the account of any Issuer when due in accordance with Section 2.03(g), such Lender agrees to pay interest on such unpaid amount for the account of such Issuer for each day
from the date such payment is due until the date such amount is paid in full to the Agent for the account of such Issuer at the Federal Funds Rate until (and including) the third Business Day after the date due and thereafter at the Base Rate. The
obligations of the Lenders under this Section 2.03 are several and not joint or joint and several, and the failure of any Lender to make available to the Agent for the account of any Issuer its Revolving Share of any Reimbursement Obligations when
due in accordance with Section 2.03(g) shall not relieve any other Lender of its obligation hereunder to make its Revolving Share of such Reimbursement Obligations so available when so due, but no Lender shall be responsible for the failure of any
other Lender to make such other Lender’s Revolving Share of such Reimbursement Obligations so available when so due. 
  

	 	(i)     (i)	Whenever any Issuer receives a payment of a Reimbursement Obligation from or on behalf of the Borrower as to which the Agent has received for the account of such Issuer any payment
from a Lender pursuant to Section 2.03(g), such Issuer shall pay to the Agent and the Agent shall promptly pay to such Lender, which payment shall be deemed a payment by the Borrower hereunder, an amount equal to such Lender’s Revolving Share
of such payment from or on behalf of the Borrower. 

  

	 	(ii)	If any payment by or on behalf of the Borrower and received by any Issuer with respect to any Letter of Credit is rescinded or must otherwise be returned by such Issuer for any
reason and such Issuer has paid to the Agent for the account of any Lender any portion thereof, then the provisions of Section 2.03(g) shall apply as if such rescission constituted a failure of the Borrower to pay, when due to such Issuer,
Reimbursement Obligations equal to such rescinded amount. 

  
 (j) Each Lender, upon the demand of any Issuer, shall reimburse such Issuer, to the extent such Issuer has not been reimbursed by the Borrower after demand therefor, for the reasonable costs and expenses (including reasonable
attorneys’ fees) incurred by such Issuer in connection with the collection of amounts due under, and the preservation and enforcement of any rights conferred by, any Letter of Credit or the performance of such Issuer’s obligations under
this Agreement in respect thereof, to the extent of such Lender’s Revolving Share of the 

  

 -31- 

 
amount of such costs and expenses. Such Issuer shall refund any costs and expenses reimbursed by such Lender that are subsequently recovered from the
Borrower in an amount equal to such Lender’s Revolving Share thereof. 
  
 (k) The obligation of each Lender to make available to any Issuer the amounts set forth in this Section 2.03 shall be absolute, unconditional and irrevocable under any and all circumstances, shall be made without
reduction for any set-off, counterclaim or other deduction of any nature whatsoever, may not be terminated, suspended or delayed for any reason whatsoever, shall not be subject to any qualification or exception and shall be made in accordance with
the terms and conditions of this Agreement under all circumstances, including, without limitation, any of the following circumstances: 
  

	 	(i)	any lack of validity or enforceability of this Agreement or any of the other Loan Documents; 

  

	 	(ii)	the existence of any claim, setoff, defense or other right which the Borrower may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of
Credit (or any Person for whom any such transferee may be acting), the Agent, any Issuer, any Lender or any other Person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated
transactions (including any underlying transaction between the Borrower and the beneficiary named in any such Letter of Credit); 

  

	 	(iii)	any draft, certificate or any other document presented under any 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; 

  

	 	(iv)	the surrender or impairment of any security for the performance or observance of any of the terms of any of the Loan Documents; and 

  

	 	(v)	the occurrence of any Default. 

  

	 	(l)      (i)	If at any time the publicly traded unsecured long-term debt securities of an Issuer (or of any bank holding company of which such Issuer is a subsidiary) or its equivalent is rated
less than A- (or the equivalent rating then in effect) by S&P or A3 (or the equivalent rating then in effect) by Moody’s, then the Borrower may, at its option, request that a new Issuer be appointed, which shall be a Lender reasonably
acceptable to the Agent, the Required Lenders and the Borrower (which acceptance shall not be unreasonably withheld) that has (or whose bank holding company has) such a rating. If the Borrower makes such a request, the Agent shall promptly appoint
such a replacement Issuer. 

  

	 	(ii)	 Subject to the appointment and acceptance of a successor Issuer as provided below, such Issuer may resign at any time by giving notice thereof to the Agent, the
Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders may, with the consent of 

  

 -32- 

	 	 
the Borrower (which consent shall not be unreasonably withheld), appoint any Eligible Assignee as the successor Issuer provided that it meets the
qualifications set forth in Section 2.03(l)(i). If no successor to such Issuer is so appointed by the Required Lenders and accepts such appointment within 30 days after the retiring Issuer’s giving of notice of resignation, then the retiring
Issuer may, on behalf of the Lenders and with the consent of the Borrower (which consent shall not be unreasonably withheld), appoint any Eligible Assignee as the successor Issuer, provided that it meets the qualifications set forth in
Section 2.03(l)(i). 

  

	 	(iii)	The acceptance of any appointment as an Issuer hereunder by a successor Issuer shall be evidenced by an agreement entered into by such successor, in a form satisfactory to the
Borrower and the Agent, and from and after the effective date of such agreement, such successor Issuer shall thereupon succeed to and become vested with all the rights, powers, privileges, duties and obligations of the removed or retiring Issuer
with respect to Letters of Credit to be issued from and after such effective date, and the removed or retiring Issuer shall be discharged from its duties and obligations as Issuer under the Loan Documents with respect to Letters of Credit to be
issued from and after such effective date. On such effective date, the Borrower shall pay all accrued and unpaid fees owed under any Loan Document to the removed or retired Issuer for acting in its capacity as an Issuer. After any retiring
Issuer’s resignation or removal as Issuer, the provisions of this Section 2.03 shall continue in effect for such Person’s benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Issuer.

  
 Section 2.04 Reduction or Termination of
Commitments. 
  
 (a) Voluntary Reduction or
Termination. The Borrower shall have the right, subject to the terms and conditions set forth in Section 3.02, on at least three Business Days’ notice to the Agent to terminate in whole or, from time to time, reduce ratably in part the
unused portion of the Total Revolving Commitment without penalty or premium; provided that each partial reduction of the Total Revolving Commitment shall be in an aggregate amount equal to the lesser of (a) $5,000,000 or an integral multiple
of $1,000,000 in excess thereof or (b) the entire unused portion of the Total Revolving Commitment. Upon receipt of any such notice, the Agent shall promptly notify each Lender of the contents thereof and the amount to which such Lender’s
Commitment is to be reduced. For purposes of this Section 2.04, the unused portion of the Total Revolving Commitment at any time is the amount equal to the Available Revolving Credit at that time. 
  
 (b) Automatic Termination. The Commitments shall be reduced to zero
and terminate on June 10, 2004 if the initial borrowing and the making of the Term Loans has not occurred on or before June 10, 2004. 
  
 (c) No Reinstatement. No termination or partial reduction of the Total Revolving Commitment or the Total Term Commitment pursuant to this Section
2.04 may be reinstated. 
  

 -33- 

 Section 2.05 Fees. 
  
 (a) Commitment Fees. The Borrower agrees to pay, without duplication, to the Agent, for the account of each Lender, a
commitment fee on such Lender’s Revolving Share of the average daily unused Available Revolving Credit from the Closing Date or the date such Lender becomes a Lender pursuant to an Assignment Agreement until the Termination Date at the rate of
0.50% per annum, calculated on the basis of a 360-day year for the actual number of days elapsed, payable in arrears on each Interest Payment Date for Base Rate Loans, on the date of any reduction of such Lender’s Commitment (to the extent
accrued and unpaid on the amount of such reduction) and on the Termination Date. 
  
 (b) Letter of Credit Fees. The Borrower shall pay (i) to the Agent, for the ratable account of the Lenders, a letter of credit fee on the Letter of Credit Undrawn Amount for each day at the rate per annum equal
to the Applicable Letter of Credit Fee Percentage in effect on such day, calculated on the basis of a 360-day year, payable in arrears on each Interest Payment Date for Base Rate Loans and on the date any Letter of Credit is cancelled or expires to
the extent accrued and unpaid on the amount subject to such cancellation or expiration and (ii) each Issuer a fronting fee for each Letter of Credit issued by such Issuer as separately agreed in writing between such Issuer and the Borrower.

  
 (c) Administrative Fee. The Borrower agrees to pay,
without duplication, to the Agent, for its own account and for account of the Issuers and/or Lenders, as applicable, an administrative fee in the amount separately agreed to in writing on the Closing Date and on each anniversary of the Closing Date.

  
 Section 2.06 Interest; Determination and Protection;
Illegality. 
  
 (a) Rates. Each Loan shall bear
interest at the rates set forth below, and the Borrower shall pay interest on the unpaid principal amount of each Loan made by each Lender from the date of such Loan until such principal amount shall be paid in full at the times and at the rates per
annum set forth below: 
  

	 	(i)	Base Rate Loans. During such periods as such Loan is a Base Rate Loan, a rate per annum equal at all times to the Adjusted Base Rate in effect from time to time and payable
on (A) each Interest Payment Date, commencing June 30, 2004, and (B) the Termination Date. 

  

	 	(ii)	Eurodollar Rate Loans. During such periods as such Loan is a Eurodollar Rate Loan, a rate per annum equal at all times during each Interest Period for such Loan to the
Adjusted Eurodollar Rate for such Interest Period, payable on (A) the last day of such Interest Period and, in the case of a Eurodollar Rate Loan having an Interest Period longer than three months, on the three-month anniversary of the first day of
such Interest Period and (B) the Termination Date. 

  

	 	(iii)	 Default Rate. After the occurrence of any Event of Default specified in Section 8.01(a) and consisting of the failure of the Borrower to pay any principal of
any Note or interest thereon or any Reimbursement Obligation 

  

 -34- 

	 	 
and during the continuance thereof, automatically and without any action by the Agent, any Issuer or any Lender, to the extent permitted by applicable law,
the outstanding Secured Obligations shall bear interest at a rate per annum equal to the Default Rate. Such interest shall be payable on demand and accrue until the earliest of (A) the waiver of such Event of Default by the Required Lenders or the
cure of such Event of Default, (B) agreement by the Required Lenders to rescind the charging of interest at the Default Rate or (C) payment in full of the Secured Obligations and termination of the Total Revolving Commitment.

  
 (b) Interest Rate Determination and
Protection; Illegality. 
  

	 	(i)	The Adjusted Eurodollar Rate for each Eurodollar Rate Loan specified in a Notice of Borrowing or a Notice of Conversion shall be determined by the Agent two Business Days before the
first day of the Interest Period applicable for such Loan. The Agent shall give prompt notice to the Borrower and the Lenders of the applicable Adjusted Eurodollar Rate determined by the Agent for purposes of Section 2.06(a)(ii), and each such
determination by the Agent shall be conclusive, absent manifest error. If for any reason the Agent is unable to determine the Adjusted Eurodollar Rate for any Eurodollar Rate Loan, the Agent shall so notify the Borrower and the Lenders, whereupon:

  

	 	(A)	such Loan will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Loan (or if such Loan is then a Base Rate Loan, will continue
as a Base Rate Loan); and 

  

	 	(B)	the obligation of the Lenders to make, or to Convert Loans into, Eurodollar Rate Loans shall be suspended until the Agent notifies the Borrower and the Lenders that the
circumstances causing such suspension no longer exist. 

  

	 	(ii)	If, with respect to any Eurodollar Rate Loans, any Lender reasonably determines that the Adjusted Eurodollar Rate for any Interest Period for such Loans will not adequately reflect
the cost to such Lender of making, funding or maintaining its Eurodollar Rate Loans for such Interest Period, such Lender shall forthwith so notify the Borrower and the Agent, whereupon: 

  

	 	(A)	each Eurodollar Rate Loan of such Lender that has been affected will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Loan; and

  

	 	(B)	 the obligation of such Lender to make, or to Convert Loans into, Eurodollar Rate Loans shall be suspended until such Lender shall 

  

 -35- 

	 	 
notify the Borrower and the Agent that the circumstances causing such suspension no longer exist. 

  

	 	(iii)	If the Borrower shall fail to deliver to the Agent a Notice of Conversion in accordance with Section 2.07 to select the duration of any Interest Period for the principal amount
outstanding under any Eurodollar Rate Loan prior to the last day of the Interest Period applicable to such Loan, such Loan will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Loan.

  

	 	(iv)	Notwithstanding any other provision of this Agreement, if any Lender shall notify the Agent and the Borrower that the introduction of, any change in the interpretation of, or any
change in, any Governmental Requirement after the date hereof makes it unlawful, or any central lender or comparable agency or other Governmental Authority asserts after the date hereof that it is unlawful, for any such Lender or its Eurodollar
Lending Office to perform its obligations hereunder to make Eurodollar Rate Loans or to fund or maintain Eurodollar Rate Loans hereunder, 

  

	 	(A)	the obligation of such Lender to make, or to Convert Loans into, Eurodollar Rate Loans shall be suspended until such Lender shall notify the Borrower and the Agent that the
circumstances causing such suspension no longer exist, and 

  

	 	(B)	each Eurodollar Rate Loan of such Lender then outstanding shall be Converted automatically into a Base Rate Loan effective on the Agent’s receipt of such notification or, if
lawful as determined by such Lender in good faith, on the last day of the Interest Period then currently applicable to such Eurodollar Rate Loan, as the case may be. 

  

	 	(v)	Each Lender will promptly notify the Borrower of any event occurring after the date of this Agreement which will cause the Adjusted Eurodollar Rate not to adequately reflect such
Lender’s costs or which makes it unlawful for such Lender to make or maintain Eurodollar Rate Loans, and will designate a different Lending Office if such designation will avoid such inadequacy or unlawfulness and will not, in the judgment of
such Lender, be otherwise disadvantageous to such Lender. 

  
 Section 2.07 Voluntary Interest Period Conversion. 
  
 (a) The Borrower may on any Business Day, on notice (“Notice of Conversion”) given by the Borrower to the Agent not later than 12:00 Noon (New York City time) (a) on the third Business Day prior to
the date of the proposed Conversion of Loans into Eurodollar Rate Loans or (b) prior to the date of the proposed Conversion of Eurodollar Rate Loans to Base Rate Loans and subject to the provisions of Section 2.06 and the provisions of Sections 4.04
and 4.05, Convert all Loans of one Type comprising the same Borrowing or Borrowings into Loans of 

  

 -36- 

 
another Type or Convert all Eurodollar Rate Loans comprising the same Borrowing or Borrowings into Eurodollar Rate Loans having a different Interest Period;
provided, however, that any Conversion of any Eurodollar Rate Loans into Base Rate Loans and of any Eurodollar Rate Loans into Eurodollar Rate Loans having a different Interest Period shall be made on, and only on, the last day of an
Interest Period for such Eurodollar Rate Loans. Each such Notice of Conversion shall specify therein the requested (i) date of such Conversion, (ii) the Loans to be Converted and (iii) if such Conversion is into Loans constituting Eurodollar Rate
Loans or Eurodollar Rate Loans having a different Interest Period, the duration of the Interest Period for each such Loan. Each Notice of Conversion shall be irrevocable and binding on the Borrower. The Agent shall promptly deliver notice of each
Conversion to each Lender. 
  
 (b) Each Conversion shall be in an
aggregate amount not less than $1,000,000 or an integral multiple of $100,000 in excess thereof. 
  
 Section 2.08 Accordion Provision. Subject to the following conditions, the Borrower shall have the right, without the consent of the Lenders, to
increase the Revolving Commitments and the Term Loans by not more than an aggregate $50,000,000 from time to time by adding to this Agreement one or more lenders who are Eligible Assignees (who shall, upon completion of the requirements stated in
this Section 2.08, constitute Lenders hereunder), or by allowing one or more Lenders to increase their Commitments hereunder. Any increase is subject to the conditions that (a) no Default or Event of Default exists at the time thereof or would be
caused thereby, (b) no Lender’s Revolving Commitment or Term Loans shall be increased without the consent of such Lender, (c) on the effective date of any such increase of the Revolving Commitments, if any, either there shall be no Revolving
Loans outstanding or there shall have been arrangements satisfactory to the Agent made to prepay all outstanding Revolving Loans, together with accrued interest thereon and any amounts payable pursuant to Section 3.04, (d) the Borrower shall have
delivered any evidence of authority for the increase, including customary legal opinions, as the Agent may reasonably request, and (e) the minimum amount of such increase shall be $25,000,000. Any prepayment made by the Borrower in accordance with
the preceding clause (c) may be made with the proceeds of Revolving Loans made by all the Lenders in connection with an increase in the Revolving Commitments simultaneously with the prepayment. The Borrower shall give the Agent five Business
Days’ notice of the Borrower’s intention to increase the Revolving Commitments or the Term Loans pursuant to this Section 2.08. Such notice shall specify each new lender and each Lender agreeing to increase its Revolving Commitment or Term
Loan, if any, the changes in amounts of Revolving Commitments and Term Loans that will result, the date on which such addition or change is to occur (which shall be a Business Day), and such other information as is reasonably requested by the Agent.
Each new lender agreeing to be added to this Agreement, and each Lender agreeing to increase its Revolving Commitment or its Term Loans, shall execute and deliver to the Agent a New Lender Agreement in substantially the form of Exhibit 2.08-1 or an
Accordion Agreement in substantially the form of Exhibit 2.08-2, pursuant to which it becomes a party hereto or increases its Revolving Commitment or Term Loans, as the case may be. In addition, an authorized officer of the Borrower shall execute
and deliver a Revolving Note or Term Note in the principal amount of the Revolving Commitment and Term Loans of each new lender, or a replacement Revolving Note or Term Note in exchange for the Note so replaced in the principal amount of the

 PAYMENTS, PREPAYMENTS, INCREASED COSTS AND TAXES 
  
 Section 3.01 Payments and Computations. 
  
 (a) Except as otherwise specified in Section 2.03 with respect to payments to
the Issuers of Reimbursement Obligations, the Borrower shall make each payment under this Agreement and under the Notes not later than 12:00 Noon (New York City time) on the day when due in Dollars to the Agent at the Agent’s Office in
immediately available funds. Each payment by the Borrower shall be made without set-off, counterclaim or other deduction whatsoever. The Agent will promptly thereafter cause to be distributed (i) like funds relating to the payment of principal or
interest or fees payable to the Lenders (to the extent received by the Agent), in each case to each Lender for the account of its applicable Lending Office, (A) first, ratably according to the amount of interest which is then due and payable to the
Lenders, (B) second, ratably according to the amount of principal which is due and payable to the Lenders and (C) third, ratably according to the amount of fees which then due and payable to the Lenders and (ii) like funds relating to the payment of
any other amount payable to any Lender (to the extent received by the Agent) to such Lender for the account of its Lending Office; and in all cases, the funds distributed shall be applied in accordance with the terms of this Agreement. Fees payable
pursuant to Section 2.05 to a Lender are for the account of such Lender’s Lending Office as such Lender shall designate by notice to the Agent. 
  
 (b) Whenever any payment hereunder or under the Notes 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, unless the next succeeding Business Day falls in a different fiscal quarter, in which case such payment shall be made on the next preceding Business Day. Any such extension of time for payment shall be included in the
computation of interest and fees payable in connection therewith. 
  
 (c) All computations of interest hereunder based on the Base Rate shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, for each day that the Prime Rate is the basis for such computation, and on the basis
of a year of 360 days for each day that the Federal Funds Rate is the basis for such computation, and all computations of interest hereunder based on the Adjusted Eurodollar Rate shall be made by the 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 is payable. Each 

  

 -38- 

 
determination by the Agent of an interest rate hereunder shall be conclusive, absent manifest error. 
  
 (d) Unless the Agent shall have received notice from the Borrower prior to
the date on which any payment is due to the Lenders that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the 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 Borrower shall not have so made such payment in full to the Agent, each Lender shall repay to the Agent
forthwith on demand such amount distributed to such Lender, together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Agent, at the Federal Funds Rate
until (and including) the third Business Day after demand is made and thereafter at the Base Rate. 
  
 (e) Subject to Section 3.03, payments of Loans shall be applied first to pay Base Rate Loans and then to pay Eurodollar Rate Loans in the order that the
Interest Periods for such Eurodollar Rate Loans end. All amounts shall be paid on the date specified therefor, whether or not such payment would require a payment of any Eurodollar Rate Loans prior to the last day of the applicable Interest Periods
therefor or would result in losses, costs or expenses compensable under Section 3.04. 
  
 Section 3.02 Mandatory Prepayments; Amortization. 
  
 (a) Permitted Replacement Debt. The Borrower shall, within one Business Day after receipt of the Net Proceeds by the Borrower or any of its
Subsidiaries from Permitted Replacement Debt, prepay the Loans comprising the same Borrowings in an aggregate principal amount equal to 100% of the Net Proceeds, together with accrued and unpaid interest to the date of such prepayment on the
principal amount paid. Each such prepayment shall be applied first to the Term Loans on a pro rata basis to the remaining installments thereof and second to permanently reduce ratably the Total Revolving Commitment by the amount of
such prepayment; provided, however, that in no event shall the prepayment of Revolving Loans in accordance with this Section 3.02 reduce the Total Revolving Commitment below the aggregate amount of Letter of Credit Obligations. No
reduction of the Total Revolving Commitment pursuant to this Section 3.02(a) may be reinstated. 
  
 (b) Asset Sales; Equity Issuances. 
  

	 	(i)	The Borrower shall, within one Business Day after receipt by the Borrower or any Subsidiary Guarantor, (A) of any Insurance Proceeds or condemnation proceeds required under Section
7.04 to be used to prepay the Term Loans or (B) of the Net Proceeds of any Equity Issuance, prepay the Term Loans in an aggregate principal amount equal to 100% of the proceeds (in the case of clause (A) above) and 50% of the Net Proceeds (in the
case of clause (B) above). 

  

	 	(ii)	 Within 360 days after the receipt by the Borrower or any Subsidiary Guarantor of any Net Proceeds from an Asset Sale, the Borrower shall 

  

 -39- 

	 	 
apply such Net Proceeds to the extent such Net Proceeds exceed $10,000,000, at its option: 

  

	 	(A)	to prepay Term Loans; or 

  

	 	(B)	to acquire a controlling interest or a joint venture interest (to the extent otherwise permitted by this Agreement) in another business or, to make a capital expenditure or
acquisition of other Property or equipment, in each case, in a business permitted under Section 7.15 (or enter into a binding commitment for any such expenditure or acquisition); provided that such binding commitment shall be treated as a permitted
application of Net Proceeds from the date of such commitment until and only until the earlier of (x) the date on which such expenditure or acquisition is consummated and (y) the 180th day following the expiration of the aforementioned 360-day
period. If the expenditure or acquisition contemplated by such binding commitment is not consummated on or before such 180th day and the Borrower shall not have applied such Net Proceeds pursuant to clause (A) above on or before such 180th day, such
commitment shall be deemed not to have been a permitted application of Net Proceeds at any time. 

  

	 	(iii)	Pending the final application of any such Net Proceeds, the Company (A) shall temporarily reduce the revolving Indebtedness under the Loans or invest such Net Proceeds in any manner
that is not prohibited by this Agreement and (B) shall not distribute such Net Proceeds to its Partners. 

  

	 	(iv)	Each such prepayment (in an aggregate amount not to exceed the Net Proceeds) shall be made together with accrued and unpaid interest to the date of such prepayment on the principal
amount paid and shall be applied pro rata basis to the remaining installments of the Term Loans. 

  
 (c) Other Mandatory Prepayments. If at any time the aggregate outstanding principal amount of the Revolving Loans and the Letter of Credit
Obligations exceeds the Total Revolving Commitment then in effect, then the Borrower shall immediately pay to the Revolving Agent for the ratable account of the Revolving Lenders the amount of such excess, together with accrued and unpaid interest
to the date of such prepayment on the principal amount prepaid. Such payment shall first be applied to any outstanding Revolving Loans, and then be held by the Agent as cash collateral for the Letter of Credit Obligations. 
  
 (d) Amortization of Term Loans. The Term Loans shall be repaid in
equal quarterly installments in amount equal to 0.25% of the original principal amount of the Term Loans (as it may be increased under Section 2.08) on March 31, June 30, September 30, and December 31 of each year beginning with September 30, 2004
and a final installment equal to the outstanding principal amount of the Term Loans on the Termination Date. 
  

 -40- 

 Section 3.03 Voluntary Prepayments. The Borrower may, on at least one Business Day’s notice
to the Agent, stating the proposed date and aggregate principal amount of the prepayment and the Type and Class of Loans to be prepaid, prepay, without premium or penalty, the outstanding principal amounts of such Loans comprising part of the same
Borrowing in whole or ratably in part, together with accrued and unpaid interest to the date of such prepayment on the principal amount prepaid. Such notice shall be irrevocable and the payment amount specified in such notice shall be due and
payable on the prepayment date described in such notice, together with accrued and unpaid interest on the amount prepaid. Partial prepayments of Loans shall be in an aggregate principal amount equal to the lesser of (a) $1,000,000 or an integral
multiple of $100,000 in excess thereof and (b) the aggregate outstanding principal amount of such Loans. Each prepayment of Term Loans shall be applied to future scheduled amortization pro rata to the remaining installments of the Term Loan.

  
 Section 3.04 Funding Losses Relating to Eurodollar Rate
Loans. 
  
 (a) If any payment of principal of, or any
Conversion of, any Eurodollar Rate Loan is made other than on the last day of an Interest Period relating to such Loan, as a result of a payment pursuant to Section 2.03(j), 3.02 or 3.03, a Conversion pursuant to Section 2.06(b)(ii) or 2.07, an
acceleration of the maturity of any Note in accordance with the terms hereof, or for any other reason, the Borrower shall, upon demand by any Lender, pay to such Lender at its Eurodollar Lending Office any amounts required to compensate such Lender
for any losses or reasonable expenses which it may actually incur by reason of the liquidation or reemployment of the amounts so prepaid or of deposits or other funds acquired by such Lender to fund or maintain such Loan. In any such case, such loss
and reasonable expense shall be equal to the sum, without duplication of amounts, of (i) the costs and expenses incurred (other than loss of the Applicable Margin) in connection with, or by reason of, any such event and (ii) an amount equal to the
excess, if any, as reasonably determined by such Lender of (A) the amount of interest which would have accrued on the amount so paid or accelerated for the period from the date of such payment or acceleration to the last day of the Interest Period
for such Loan at the Adjusted Eurodollar Rate (minus the Applicable Margin) applicable to such Loan over (B) the amount of interest, as reasonably determined by such Lender, which would have accrued to such Lender on such amount by placing such
amount on deposit for a comparable period with prime banks in the London interbank market. 
  
 (b) The Borrower shall indemnify each Lender against any loss or reasonable expense incurred by such Lender as a result of (i) any failure by the Borrower to fulfill on the date of any proposed Borrowing of or
Conversion into a Eurodollar Rate Loan the applicable conditions set forth in Article IV or (ii) any failure by the Borrower to make a Borrowing of or Conversion into a Eurodollar Rate Loan after the Borrower has given a notice requesting the same
in accordance with the provisions hereof. In any such case, such loss and reasonable expense shall be equal to the sum, without duplication of amounts, of (i) the costs and expenses incurred (other than loss of the Applicable Margin) by such Lender
by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to effect or maintain such Eurodollar Rate Loan in connection with, or by reason of, any such event and (ii) an amount equal to the excess, if any, as
reasonably determined by such Lender of (A) the amount of interest which would have accrued on the amount of the Eurodollar Rate Loan that was to have been made or into which another Loan was to have been Converted for the period from the date such
Borrowing or 

  

 -41- 

 
Conversion was to have been made to the last day of the Interest Period for such Loan that would have commenced on such date at the Adjusted Eurodollar Rate
(minus the Applicable Margin) applicable to such Loan over (B) the amount of interest, as reasonably determined by such Lender, which would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with
prime banks in the London interbank market. 
  
 (c) Any Lender
demanding payment pursuant to this Section 3.04 shall deliver to the Borrower a statement reasonably setting forth the amount and manner of determining the loss or expense for which such demand is made, which statement shall be conclusive, absent
manifest error. 
  
 Section 3.05 Increased Costs; Capital
Adequacy. 
  
 (a) If after the date of this Agreement
any change in any applicable Governmental Requirement (including, without limitation, the adoption of any new Governmental Requirement) or in the interpretation or administration thereof by any central bank or comparable agency or any other
Governmental Authority charged with the interpretation or administration thereof (whether or not having the force of law) shall impose, modify or deem applicable any reserve, special deposit or similar requirement against Property of, deposits with
or for the account of or credit extended by any Lender or any Issuer (except any such reserve requirement that is reflected in the Eurodollar Rate Reserve Percentage), or shall impose on such Lender or such Issuer or the London interbank market any
other condition affecting this Agreement or Eurodollar Rate Loans made by such Lender or any Letter of Credit or participation therein, and the result of any of the foregoing shall be to increase the cost to such Lender or such Issuer of making or
maintaining any Eurodollar Rate Loan or increase the cost to such Lender or such Issuer of issuing or maintaining any Letter of Credit, paying or funding any draw request thereunder or purchasing or maintaining a participation therein, or to reduce
the amount of any sum received or receivable by such Lender hereunder or such Issuer hereunder or under any Letter of Credit Reimbursement Agreement (whether of principal, interest, fees or otherwise) by an amount reasonably determined by such
Lender or such Issuer to be material, then the Borrower will pay to such Lender or such Issuer, as the case may be, following receipt of a notice from such Lender or such Issuer, as the case may be, to such effect, such additional amount or amounts
as will compensate such Lender or such Issuer, as the case may be, for such additional costs incurred or reduction suffered. 
  
 (b) If any Lender or any Issuer shall have determined that (i) the adoption after the date of this Agreement of any Governmental Requirement, guideline or
directive regarding capital adequacy, (ii) any change after the date of this Agreement in any such Governmental Requirement, guideline or directive or in the interpretation or administration thereof after the date of this Agreement by any central
bank or comparable agency or any other Governmental Authority charged with the interpretation or administration thereof or (iii) compliance by any Lender (or any lending office of such Lender) or any Issuer or any Lender’s or any Issuer’s
holding company with any request or directive regarding capital adequacy issued after the date of this Agreement under any Governmental Requirement or guideline (whether or not having the force of law) of any Governmental Authority has or would have
the effect of reducing the rate of return on such Lender’s or such Issuer’s capital or on the capital of such Lender’s or such Issuer’s holding company, if any, as a consequence of this Agreement, the Commitment of such 

  

 -42- 

 
Lender or the Loans made by such Lender or participations in Letters of Credit purchased by such Lender pursuant hereto or the Letters of Credit issued by
such Issuer pursuant hereto to a level below that which such Lender or such Issuer or such Lender’s or such Issuer’s holding company could have achieved but for such applicability, adoption, change or compliance (taking into consideration
such Lender’s or such Issuer’s policies and the policies of such Lender’s or such Issuer’s holding company with respect to capital adequacy) by an amount reasonably determined by such Lender or such Issuer to be material, then
from time to time the Borrower will pay to such Lender or such Issuer, as the case may be, following receipt of a notice from such Lender or such Issuer, as the case may be, to such effect, such additional amount or amounts as shall compensate such
Lender or such Issuer or such Lender’s or such Issuer’s holding company for any such reduction suffered. 
  
 (c) Any Issuer or any Lender requiring payment under this Section 3.05 shall deliver to the Borrower a statement reasonably setting forth the amount and
manner of determination thereof, which statement shall be conclusive, absent manifest error. 
  
 (d) Each Lender will promptly notify the Borrower of any event occurring after the date of this Agreement of which it has knowledge which will entitle such Lender to compensation pursuant to this Section 3.05 and will
designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Lender, be otherwise disadvantageous to such Lender.

Lender, such Issuer or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted

 (c) The Borrower shall indemnify each Lender, each Issuer and the Agent for the full amount of Taxes and Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section
3.06) paid by such Lender, such Issuer or the Agent (as the case may be) and all liabilities (including penalties, additions to tax, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes

any Secured Obligation from any account located outside the United States or any such payment is made by a payor that is not a United States Person and if no Taxes are payable in respect of such payment, the Borrower shall furnish to the applicable
Lenders, the Issuers, and the Agent a certificate from each appropriate taxing authority, or an opinion of counsel acceptable to the Agent, in either case stating that such payment is exempt from or not subject to Taxes. For purposes of this Section

Lending Office under this Agreement free from withholding of United States federal income tax; 

  

	 	(iii)	it shall, before or promptly after the occurrence of any event (including the passing of time, but excluding any event mentioned in clause (ii) above) requiring a change in the most
recent forms or form previously delivered by such Lender pursuant to this Section 3.06(e) and if the delivery of the same be lawful, deliver to the Borrower through the Agent, with a copy to the Agent, two accurate and complete original signed
copies of Form 4224 or Form 1001, as applicable, or a Form W-8 in replacement for the forms or form previously delivered by such Lender; and

be required from time to time by any applicable Governmental Requirement, treaty, rule or regulation in order to establish such Lender’s tax status for withholding purposes. 

  
 (f) The obligations of the Borrower contained in this Section 3.06 shall
survive the termination of this Agreement and the payment in full of the Secured Obligations. 
  
 Section 3.07 Substitution of Lender. If (a) the obligation of any Lender to make or Convert Loans into Eurodollar Rate Loans has been suspended pursuant to Section 2.06(b), (b) any Lender has demanded
compensation under Section 3.05 or (c) any Lender has notified the Borrower that it is not capable of receiving payments without deduction or withholding pursuant to Section 3.06, the Borrower may replace such Lender by designating in a notice given
to the Agent an Eligible Assignee to replace such Lender, which Eligible Assignee, if not already a Lender, shall be subject to the approval of the Issuers and Agent, which approval shall not be unreasonably withheld. If the Borrower so designates
an Eligible Assignee, then the Agent shall give notice thereof to the Lender to be replaced, and thereupon, such Lender shall promptly consummate an assignment of such Lender’s Commitment, Loans, Notes, participations in Letters of Credit and
other rights and obligations hereunder relative to the Commitment of such Lender to such Eligible Assignee in accordance with Section 10.06. For purposes of Section 3.04(a), a Lender consummating an assignment pursuant to this Section 3.07 shall be

partnership or a foreign corporation, as the case may be, in good standing, when applicable, in each jurisdiction in which it owns or leases Property or proposes to own or lease Property or in which the carrying on of its business as now conducted

delivered by the Borrower and are, or when so delivered will be, the legal, valid and binding obligations of the Borrower, enforceable against the Borrower in accordance with their respective terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). The execution,
delivery and performance in accordance with their respective terms by the Borrower of the Loan Documents to which it is a party, and the incurrence of Indebtedness and other Secured Obligations pursuant thereto, do not and will not (a) violate,

with all Governmental Requirements applicable to it or any of its Property, including, without limitation, all applicable Governmental Requirements under ERISA and Environmental Laws, except for such noncompliances by the Borrower and the Subsidiary
Guarantors that individually or in the aggregate could not reasonably be expected to have a Material Adverse Effect. Each of the Borrower and its Subsidiary Guarantors has no knowledge of any condition, event, circumstance, act or omission that
could reasonably be expected to form the basis of any Litigation regarding noncompliance with or cleanup responsibility under Environmental Laws, which, if such condition, event, circumstance, act, or omission is true and remains unremedied, could

as are required by GAAP or (b) Taxes, other than Federal Taxes and Taxes payable to Alabama and Texas Governmental Authorities, to which this clause (b) does not relate, the nonpayment of which individually or in the aggregate could not reasonably

(other than required insurance premiums, all of which that have become due have been paid) has been incurred and not satisfied in full by the Borrower or any ERISA Affiliate of the Borrower with respect to any Benefit Plan; and no event or condition
has occurred, or is reasonably expected to occur, which presents a material risk of the termination of any Benefit Plan under circumstances which could result in a material liability to the Borrower, directly or indirectly or as a result of the
liability of a current or former ERISA Affiliate of the Borrower; provided, however, for purposes of this Section 5.09(a), a liability shall be considered material at any time

used by Lyondell immediately prior to July 1, 1993, and as the same have been used by the Borrower immediately prior to the date of this Agreement and as they are intended as of the date of this Agreement to be used by the Borrower after such date
in the operation of the Refinery in a manner consistent with the Borrower’s past practices, and any defect in title to any portion of the Company Pipelines and the Easements will not or could not reasonably be expected to have a Material
Adverse Effect. In each case, free and clear of all Liens except for Permitted Liens, the Borrower has good and valid title to all its other tangible Property that individually or in the aggregate are Material, and each Subsidiary Guarantor has good
and valid title to all its tangible Property that individually or in the aggregate with the tangible Property purported to be owned by all Subsidiary Guarantors are Material. All Property consisting of leases of Property by the Borrower and the
Subsidiary Guarantors which individually or in the aggregate are Material are valid and subsisting and in full force and effect, the Borrower and the Subsidiary Guarantors enjoy the quiet and undisturbed possession of such leased Property and no
default exists under such leases, except for such lack of such enjoyment and defaults that individually or in the aggregate could not reasonably be expected to have a Material Adverse Effect. 
  
 Section 5.11 Labor Matters. There are no strikes, work stoppages,
slowdowns or lockouts pending or, to the knowledge of the Borrower, threatened against or involving the Borrower or any Subsidiary Guarantor, other than those that individually or in the aggregate could not reasonably be expected to have a Material

 Section 5.13 Use of Proceeds. The Borrower will use (a) the proceeds
of the Revolving Loans solely for working capital and general business purposes (including, in relation to the initial Borrowing of the Revolving Loans hereunder, to refinance Indebtedness of the Borrower outstanding under the Existing Revolving
Credit Agreement) and (b) request the issuance of 

  

 -56- 

 
Letters of Credit consistent with such purposes. None of the proceeds of the Loans will be used to purchase or carry (or refinance any borrowing the proceeds
of which were used to purchase or carry) any “margin stock” within the meaning of Regulation T, U or X. Neither the Borrower nor any Subsidiary owns any margin stock. The Borrower does not intend to apply, nor will it apply, any part of
the proceeds of any Loan in any manner or to any purpose that is unlawful or would involve a violation of any Governmental Requirement relating to the use of funds applicable to the Borrower or the transactions contemplated by the Loan Documents,

with the filing of UCC financing statements in the offices set forth on Schedule 5.15, creates an Acceptable Security Interest in the Collateral described in such Security Document. No filings, recordings, Governmental Approvals, registrations, or
third party consents are required in order to perfect an Acceptable Security Interest in the Collateral granted under any Security Document except for filings or recordings which are the subject of arrangements, satisfactory to the Collateral Agent,
for filing or recording on or promptly after the date hereof. Such Collateral constitutes and includes all Property of the Borrower other than Excluded Property. There are no material prohibitions on the pledge of the Collateral. 
  
 Section 5.16 Perfection of Collateral. All executed originals of each
promissory note or similar instrument that constitutes or evidences Collateral either (a) are in the possession of the Borrower, or (b) have been delivered to the Collateral Agent, or (c) if possession thereof is through a third party custodian
other than the Collateral Agent, either (i) the Borrower and the Collateral Agent have received a written acknowledgment from such custodian that such custodian is holding the promissory note or similar instrument, as applicable, that constitute or
evidence the Collateral solely on behalf of and for the benefit of the Collateral Agent, acting for the benefit of the Secured Parties, or (ii) the Borrower and the Collateral Agent have received a written acknowledgement from such custodian that
such custodian is acting solely as agent of the Collateral Agent. The Lenders, the Issuers, the Agent, and the Collateral Agent agree that the Borrower is not required to perfect the security interest of the Collateral Agent on Titled Vehicles,
deposit accounts, securities accounts, or other money now or hereafter owned by the Borrower, notwithstanding anything herein or in the Security Agreements to the contrary, and each representation and warranty, covenant, or other provision in this
Agreement relating to the Titled Vehicles, deposit accounts, securities accounts, or other money shall be modified by this sentence as though fully set forth therein and made a part thereof. 
  
 Section 5.17 Priority of Liens on Collateral. The Borrower has not
authorized the filing of and has no knowledge of any financing statements against the Borrower that includes a description of any part of the Collateral other than any financing statement relating to the Liens granted to the Collateral Agent for the
benefit of the Secured Parties under the Security

Person other than the Collateral Agent, for the benefit of the Secured Parties.

 CERTAIN COVENANTS 
  
 So long as any of the Revolving Commitments remain in effect and until

each jurisdiction in which its ownership or lease of properties or its transaction of business requires it to be registered, qualified or licensed, except to the extent that failures to be so registered, qualified or licensed individually or in the

its business or the ownership of its Property, except to the extent that the failure to keep and maintain such rights, franchises, licenses, permits, and privileges individually or in the aggregate by the Borrower and all Subsidiary Guarantors could
not reasonably be expected to have a Material Adverse Effect. 
  
 (b) The Borrower shall and shall cause each Subsidiary Guarantor to maintain and preserve all of its tangible personal Property, owned or leased, that is necessary or useful in the conduct of its business in good repair, working order and
condition, ordinary wear and tear excepted; provided, however, that no item of tangible personal Property need be so maintained and preserved if the failure to so maintain and preserve such item individually or in the aggregate with

 (c) The Borrower shall and shall cause each Subsidiary Guarantor to maintain and protect its ownership of or rights to use
all Intellectual Property owned or used by it in the conduct of its business as now conducted and proposed to be conducted, in each case free of all claims and infringements known to the Borrower, except for such failure so to maintain and protect

aggregate could not reasonably be expected to have a Material Adverse Effect. 
  
 (b) The Borrower shall and shall cause each Subsidiary Guarantor to maintain a policy which, in the reasonable business judgment of the Borrower, is reasonably designed to promote and monitor continued compliance by

supplies or otherwise that, if unpaid, might give rise to a Lien (other than a Permitted Lien) on such Property or any part thereof; provided, however, that such payment and discharge by such Person shall not be required with respect
to any such Tax or claim so long as the failure to make such payment and effect such discharge, together with all other failures then and theretofore permitted by this clause, could not reasonably be expected to have a Material Adverse Effect.

with financially sound and reputable insurance companies or associations, insurance with the same policy limits, coverage provisions, deductibles, co-insurance limits, waiting periods, and other requirements as contained within the policies the
Borrower maintained on the Closing Date, including, without limitation, public liability insurance, property insurance against loss or damage to its Property, and business interruption insurance; provided that Borrower and its Subsidiary
Guarantors may make changes to the insurance that existed on the Closing Date that cause (i) reductions in policy limits, (ii) decreases in coverage provisions, (iii) increases in deductibles or co-insurance limits, (iv) increases in waiting
periods, or (v) material changes to any other provision, so long as any such change remains consistent with coverage provisions, deductibles, co-insurance limits, waiting periods, and other provisions that a prudently operated chemical or refining
company with a single plant location financed with secured debt would maintain, as determined by a nationally recognized insurance broker or consultant (which may be the Borrower’s insurance broker or consultant). The Borrower shall cause the

the Collateral Agent of property Insurance Proceeds and proceeds from condemnation in excess of $50,000,000, for which all necessary repairs and replacements to such affected Collateral affected by such event could reasonably be expected to be
substantially completed within nine (9) months (or such longer period as reasonably may be required, not to exceed fifteen (15) months) following such event then, so long as no Event of Default shall have occurred and be continuing, Borrower or such
Subsidiary Guarantor shall diligently proceed within such time periods to effect the repair or restoration of such affected Collateral as may be reasonably necessary to continue or resume operating the Refinery in the ordinary course of business,
and all property Insurance Proceeds and proceeds from condemnation received by the Borrower, such Subsidiary Guarantor, or the Collateral Agent as a result of such event shall be applied, to the extent necessary, in payment for such repairs to and
replacement of such affected Collateral or, to the extent the costs of such repairs and replacements shall have been paid by the Borrower or one of its Subsidiary Guarantors, to reimburse such Person. If such repairs and replacements could not
reasonably be made within the time period required in the preceding sentence, then all property Insurance Proceeds or condemnation proceeds received in connection with such event shall be applied to repay the Secured Obligations in accordance with

Subsidiary Guarantor to use any proceeds that are subject to this Section 7.04(c)(i) for reinvestment in Property for any of the lubes, aromatics or refining businesses of the Borrower, or in the case of proceeds received in respect of the Property
of such Subsidiary Guarantor, the business of the Borrower or such Subsidiary Guarantor. 

  

	 	(ii)	 If an event which gives rise to the receipt of Insurance Proceeds or condemnation proceeds by the Borrower, any Subsidiary Guarantor, or the Collateral Agent causes
an Event of Default, or if Insurance Proceeds or condemnation proceeds are received during the existence and continuation of an Event of Default, all Insurance Proceeds or condemnation proceeds received by the Borrower, any of its Subsidiary

preserve, protect or validate any Liens granted pursuant to the Security Documents on any Collateral or to enable the Collateral Agent to exercise and enforce its rights under any Security Document with respect to such Liens (including seeking all
applicable regulatory authorizations to facilitate any foreclosure on Collateral) and (b) promptly upon request by the Collateral Agent, or any Lender through the Agent, correct, and cause each of its Subsidiary Guarantors promptly to correct, any

 Section 8.02 Remedies.
During the continuance of any Event of Default (other than one specified in Section 8.01(e)), the Agent, on notice to the Borrower, may (but shall not be obligated to), and if so directed by the Required Lenders shall, do any or all of the
following: (a) declare, in whole or, from time to time, in part, the Secured Obligations to be, and the Secured Obligations shall thereupon and to that extent become, due and payable; (b) demand that the Borrower deliver cash collateral to the Agent
in an amount equal to the aggregate amount of the then Letter of Credit Undrawn Amount to be held in accordance with Section 8.04, whereupon the Borrower shall be obligated to deliver such cash collateral immediately; and (c) terminate, in whole or,
from time to time, in part, the Commitments (other than the Commitments to make Loans pursuant to the second and last sentences of Section 2.03(g)); provided, however, that during the continuance of an Event of Default specified in
Section 8.01(l), the Agent shall not be entitled to declare, in whole or in any part, the Secured Obligations to be due and payable, or to exercise any of the other rights or remedies set forth in this Section 8.02, solely by reason of such
continuance, and none of the Agent, any Issuer or any Lender shall be entitled to exercise any of its rights or remedies under Section 8.05 or 10.02(c) or the proviso to the second sentence of Section 6.03 solely by reason of such continuance,
unless and until the date (the “Supply Termination Date”), if any, the Borrower receives a written notice of termination of the Crude Supply Agreement by the “Supplier” (as defined in the Crude Supply Agreement) pursuant
to Section 3.2(c)(iv) or (v) of the Crude Supply Agreement, as applicable, by reason of the occurrence of such Event of Default; and provided, further, that any Event of Default specified in Section 8.01(l) which occurs shall
automatically be cured and no longer continuing upon the earlier to occur prior to the Supply Termination Date, if any, applicable thereto of (i) receipt by the Borrower of written evidence reasonably satisfactory to the Required Lenders of such
Supplier’s waiver of its right to terminate the Crude Supply Agreement pursuant to Section 3.2(c)(iv) or (v) thereof, as applicable, by reason of the occurrence of such Event of Default or (ii) the passage of the 90-day period provided under
such Section 3.2(c)(iv) or (v), as applicable, without such Supplier’s having delivered such Supplier’s notice of termination of the Crude Supply Agreement by reason of the occurrence of such Event of Default. Upon the occurrence of an
Event of Default specified in Section 8.01(e), automatically and without any notice to the Borrower, (a) the principal of and accrued and unpaid interest on the Notes and all other Secured Obligations then owing under the Loan Documents shall be due
and payable and (b) the Commitments (other than the Commitments to make Loans pursuant to the second and last sentences of Section 2.03(g)) shall terminate. Presentment, demand, protest, notice of protest, notice of default, notice of dishonor,
notice of intent to accelerate and all other notices of any kind (other than the notice provided for in the first sentence of this Section 8.02) are hereby expressly waived by the Borrower. 
  

 -75- 

 Section 8.03 Application of Proceeds. During the continuance of any Event of Default, (X) all
payments in respect of the Secured Obligations received by the Agent may, and shall on the acceleration of the Secured Obligations pursuant to Section 8.01(e), and (Y) all proceeds of any sale of, or other realization upon, all or any part of the
Collateral shall, be applied by the Agent as follows: 
  
 (a)
first, to pay (i) interest on and the principal of any portion of any Loan which the Agent has advanced on behalf of any Lender and (ii) any amount in respect of a drawing under a Letter of Credit which the Issuer has paid, in either case, for which
the Agent or such Issuer has not then been reimbursed by any Lender or the Borrower; 
  
 (b) second, to pay Secured Obligations in respect of any fees, expense reimbursements or indemnities then due to the Agent, the Collateral Agent, or the Issuers; 
  
 (c) third, to pay Secured Obligations in respect of any expense
reimbursements or indemnities then due to the Lenders; 
  
 (d)
fourth, to pay interest, commitment fees, letter of credit fees, and other fees due in respect of the Loans; 
  
 (e) fifth, to pay or prepay principal outstanding on the Loans; 
  

(f) sixth, to pay all Secured Obligations owed to Lenders in respect of any Hedging Arrangements respecting the Loans; 
  
 (g) seventh, to pay all other Secured Obligations; and 
  
 (h) eighth, any excess shall be paid to the Borrower. 
  
 The Borrower shall remain liable to the Agent, the Collateral Agent, the Issuers, and the
Lenders, the deficiency. If the Agent has funds available to apply to a portion of, but not all of, one of the amounts described in clauses (a) through (g) above, then the Agent shall apply such funds to the applicable parties in proportion to the
amounts to which such parties would have been entitled if the entire amount described in any such clause had been available. 
  
 Section 8.04 Cash Collateral. If cash collateralization of any Letter of Credit Obligations is required pursuant to any provision of any of the
Loan Documents, including, without limitation, Section 8.02, then such cash collateralization shall be made by deposit by the Borrower of Dollars in immediately available funds, in the amount of such required cash collateralization, into a
non-interest bearing cash collateral account at the Agent’s Office, which account shall be under the sole dominion and control of the Collateral Agent and is hereby pledged to the Collateral Agent for the benefit of itself, the Agent, the
Issuers and the Lenders as security for the payment of any Letter of Credit Obligations and any other Secured Obligations that may become payable under any Loan Documents. Funds deposited in such account shall (a) automatically be applied by the
Agent to reimburse the Issuers for all Reimbursement Obligations the Borrower has not paid, and thereafter (b) may be applied by the Agent against the Letter of Credit Obligations as they become due or, if the maturity of the Loans has been
accelerated, against payment of any other Secured Obligations under the Loan Documents as 

  

 -76- 

 
such amounts become due. Any funds remaining in such account when all Letter of Credit Obligations and all other Secured Obligations payable under the Loan
Documents have been paid shall be promptly remitted to the Borrower. 
  
 Section 8.05 Set-Off; Suspension of Payment and Performance. The Agent, each Issuer and each Lender are hereby authorized by the Borrower, to the extent permitted under Governmental Requirements, at any time and from time to time,
without notice, during any Event of Default, to set-off against, and to appropriate and apply to the payment of, the Secured Obligations owing to such Person (whether matured or unmatured, fixed or contingent or liquidated or unliquidated and
including amounts to which such Person is entitled with respect to Letter of Credit Obligations), any and all liabilities owing by such Person to the Borrower (whether payable in Dollars or any other currency, whether matured or unmatured and, in
the case of liabilities that are deposits, whether general or special, time or demand and however evidenced and whether maintained at a branch or office located within or without the United States). The rights of the Agent, each Issuer and each
Lender under this Section 8.05 are in addition to and cumulative of all other rights and remedies (including, without limitation, rights pursuant to any banker’s lien) which such Person may have. 
  
 Section 8.06 Sharing of Recoveries. The Agent, each Issuer and each
Lender agrees that if, for any reason (whether voluntary, involuntary, through the exercise of any right of set-off or otherwise), such Person receives payment of a proportion of the aggregate amount of Secured Obligations due and payable to it
hereunder that is greater than its allocable share thereof, then the Person receiving such proportionately greater payment shall purchase participations (which it shall be deemed to have done simultaneously upon the receipt of such payment) in the
rights of the applicable Persons hereunder so that all such recoveries with respect to the Secured Obligations (net of costs of collection) shall be properly allocated among the Persons entitled to the same; provided, however, that if
all or part of such proportionately greater payment received by the purchasing Person is thereafter recovered by or on behalf of the Borrower from such Person, such purchases shall be rescinded and the purchase prices paid for such participations
shall be returned to such Person to the extent of such recovery, but without interest (unless the purchasing Person is required to pay interest on the amount recovered to the Person recovering such amount, in which case the selling Lender shall be
required to pay interest at a like rate). The Borrower expressly consents to the foregoing arrangements and agrees that any holder of a participation in any rights hereunder so purchased or acquired pursuant to this Section 8.06 shall, with respect
to such participation, to the extent permitted under Governmental Requirements, be entitled to all of the rights of a Lender and may exercise any and all rights of set-off with respect to such participation as fully as though the Borrower were
directly indebted to the holder of such participation for Secured Obligations in the amount of such participation. 
  
 ARTICLE IX 
  
 THE AGENT 
  
 Section 9.01 Appointment and
Powers. 
  
 (a) Each Lender hereby irrevocably appoints and
authorizes the Agent to act as the agent for such Lender under this Agreement with such powers as are delegated to the Agent by the 

  

 -77- 

 
terms thereof, together with such other powers as are reasonably incidental thereto. The Agent’s duties shall be purely ministerial and the Agent shall
have no duties or responsibilities except those expressly set forth herein. The Agent shall not be required under any circumstances to take any action that, in its judgment, (a) is contrary to any provision of the Loan Documents or Governmental
Requirements or (b) would expose it to any liability or expense against which it has not been indemnified to its satisfaction. The Agent, by reason of its serving as an agent, shall not be a trustee or other fiduciary for any Lender.

  
 (b) Each Lender, each Issuer, and the Agent hereby irrevocably
appoint and authorize the Collateral Agent to act as the collateral agent for such Lender, Issuer, or Agent under this Agreement with such powers as are delegated to the Collateral Agent by the terms thereof, together with such other powers as are
reasonably incidental thereto. The Collateral Agent’s duties shall be purely ministerial and the Collateral Agent shall have no duties or responsibilities except those expressly set forth herein and in the Security Documents. The Collateral
Agent shall not be required under any circumstances to take any action that, in its judgment, (a) is contrary to any provision of the Loan Documents or Governmental Requirements or (b) would expose it to any liability or expense against which it has
not been indemnified to its satisfaction. The Collateral Agent, by reason of its serving as a collateral agent, shall not be a trustee or other fiduciary for any Lender, Issuer, or Agent. 
  
 Section 9.02 Limitation on Agent’s Liability. Neither the Agent nor any of its directors, officers, employees or
agents shall be liable or responsible to any Issuer or any Lender for any action taken or omitted to be taken by them under or in connection with the Loan Documents, except for its or their own gross negligence or willful misconduct. The Agent shall
not be responsible to any Issuer or any Lender for (a) any recitals, statements, representations or warranties contained in the Loan Documents or in any certificate or other document referred to or provided for in, or received by any Issuer or any
Lender under, the Loan Documents, (b) the validity, effectiveness or enforceability of the Loan Documents or any such certificate or other document or (c) any failure by the Borrower to perform any of its obligations under the Loan Documents. The
Agent may employ agents and attorneys-in-fact and shall not be responsible to any Issuer or any Lender for the negligence or misconduct of any such agents or attorneys-in-fact so long as the Agent was not grossly negligent in selecting or directing
such agents or attorneys-in-fact. The Agent shall be entitled to rely upon any certification, notice or other communication (including any thereof by telephone, telex, telecopier, telegram or cable) believed by it to be genuine and correct and to
have been signed or given by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants or other experts selected in good faith by the Agent. As to any matters not expressly provided for by
the Loan Documents, the Agent shall in all cases be fully protected as to the Issuers and the Lenders in acting, or in refraining from acting, under the Loan Documents in accordance with instructions signed by the Required Lenders, and such
instructions of the Required Lenders and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders. 
  
 Section 9.03 Defaults. The Agent shall not be deemed to have knowledge of the occurrence of a Default unless the Agent has received notice from a
Lender, an Issuer or the Borrower specifying such Default and stating that such notice is a “Notice of Default.” If the Agent receives such a notice of the occurrence of a Default, then the Agent shall give prompt 

  

 -78- 

 
notice thereof to the Lenders and the Issuers. In the event of any Default, the Agent shall take such action with respect to such Default as shall be
directed by the Required Lenders. Unless and until the Agent has received such directions, in the event of any Default, the Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default
as it deems advisable in the best interests of the Lenders. 
  
 Section 9.04 Rights as a Lender. The Agent shall, in its capacity as a Lender, have the same rights and powers under the Loan Documents as any other Lender and may exercise the same as though it were not acting as the Agent, and the
term “Lender” or “Lenders” shall include such Person in its individual capacity. Each Person acting as the Agent and its Affiliates may (without having to account therefor to any Lender) accept deposits from, lend money to and
generally engage in any kind of banking, trust or other business with the Borrower, the Subsidiary Guarantors and the Borrower’s Affiliates as if it were not acting as the Agent, and such Person and its Affiliates may accept fees and other
consideration from the Borrower, the Subsidiary Guarantors and the Borrower’s Affiliates for services in connection with the Loan Documents or otherwise without having to account for the same to the Lenders. 
  
 Section 9.05 Indemnification. The Lenders agree to indemnify the Agent
or the Collateral Agent (to the extent not reimbursed by the Borrower under the Loan Documents), ratably in proportion to their respective Pro Rata Shares, for any and all liabilities, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind and nature whatsoever that may be imposed on, incurred by or asserted against the Agent in its capacity as agent or the Collateral Agent in its capacity as collateral agent (including, without limitation, the
costs and expenses that the Borrower is obligated to pay under the Loan Documents) in any way connected with, relating to or arising out of the Loan Documents or any other documents contemplated thereby or referred to therein or the transactions
contemplated thereby or the enforcement of any of the terms thereof or of any such other documents, provided that no Lender shall be liable for any of the foregoing to the extent they arise from gross negligence or willful misconduct by the Agent or
the Collateral Agent. The obligations of the Lenders under this Section 9.05 shall survive the termination of this Agreement and the payment in full of the Secured Obligations. 
  
 Section 9.06 Non-Reliance on Agent and Other Lenders. Each Lender agrees that it has made and will continue to make,
independently and without reliance on the Agent or any other Lender, and based on such documents and information as it deems appropriate, its own credit analysis of the Borrower and the Subsidiary Guarantors, and its own decision to enter into the
Loan Documents and to take or refrain from taking any action in connection therewith. The Agent shall not be required to keep itself informed as to the performance or observance by the Borrower of the Loan Documents or any other document referred to
or provided for therein or to inspect the properties or books of the Borrower or any Subsidiary Guarantor. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders and the Issuers by the Agent
under the Loan Documents, the Agent shall have no obligation to provide any Lender or any Issuer with any information concerning the business, status or condition of the Borrower or any Subsidiary Guarantor or the Loan Documents which may come into
the possession of the Agent or any of its Affiliates.

 Section 9.07 Resignation of the Agent and Collateral Agent. 
  
 (a) Resignation of the Agent. Subject to the appointment and
acceptance of a successor Agent as provided below, the Agent may resign at any time by giving notice thereof to the Lenders, the Issuers and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders may, with, if no Event of
Default exists, the consent of the Borrower (which consent shall not be unreasonably withheld), appoint any Eligible Assignee as the successor Agent. If no successor Agent is so appointed by the Required Lenders and accepts such appointment within
30 days after the resigning Agent’s giving of notice of resignation, then the resigning Agent may, on behalf of the Lenders and with the consent of the Borrower (which consent shall not be unreasonably withheld), appoint any Eligible Assignee
as the successor Agent. Effective on the acceptance by any Person of its appointment as a successor Agent, such Person shall succeed to and become vested with all the rights, powers, privileges, duties and obligations of the resigning Agent and the
resigning Agent shall be discharged from its duties and obligations as Agent under the Loan Documents. After any resigning Agent’s resignation as Agent, the provisions of this Article IX shall continue in effect for its benefit in respect of
any actions taken or omitted to be taken by it while it was acting as the Agent. The Lenders, the Agent, and the Borrower agree that (i) if the Agent is removed or replaced as Agent, by resignation or otherwise, under this Agreement, then the entity
being removed or replaced as Agent will simultaneously resign as Collateral Agent, and (ii) no successor Agent will be appointed or accepted under this Agreement unless such party shall simultaneously be appointed or accepted as Collateral Agent and
shall agree to such simultaneous appointment or acceptance as Collateral Agent. 
  
 (b) Resignation of the Collateral Agent. Subject to the appointment and acceptance of a successor Collateral Agent as provided below, the Collateral Agent may resign at any time by giving notice thereof to the
Secured Parties and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders may, with the consent of the Borrower (which consent shall not be unreasonably withheld), appoint any Eligible Assignee as the successor
Collateral Agent. If no successor Collateral Agent is so appointed by the Required Lenders and accepts such appointment within 30 days after the resigning Collateral Agent’s giving of notice of resignation, then the resigning Collateral Agent
may, on behalf of the Secured Parties and with the consent of the Borrower (which consent shall not be unreasonably withheld), appoint any Eligible Assignee as the successor Collateral Agent. Effective on the acceptance by any Person of its
appointment as a successor Collateral Agent, such Person shall succeed to and become vested with all the rights, powers, privileges, duties and obligations of the resigning Collateral Agent and the resigning Collateral Agent shall be discharged from
its duties and obligations as Collateral Agent under the Loan Documents. After any resigning Collateral Agent’s resignation as Collateral Agent, the provisions of this Article IX shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as the Collateral Agent. The Lenders, the Agent, the Collateral Agent, the Issuers, and the Borrower agree that (i) if the Collateral Agent is removed or replaced as Collateral Agent, by
resignation or otherwise, under this Agreement, then the entity being removed or replaced as Collateral Agent will simultaneously resign as Agent, and (ii) no successor Collateral Agent will be appointed or accepted under this Agreement unless such
party shall simultaneously be appointed or accepted as Agent and shall agree to such simultaneous appointment or acceptance as Agent.

Section 10.05, all of the Lenders). 
  
 (b) (i) The Lenders, the
Issuers, the Agent, and the Collateral Agent agree with the Borrower that upon payment in full of all principal of, and interest on, the Loans and all other accrued and payable Secured Obligations and termination of the Commitments and all Letters
of Credit, at the Borrower’s expense, the Collateral Agent shall promptly take all actions and execute and cause or authorize to be filed or recorded all releases, agreements, documents, or instruments (and file terminations of financing
statements and/or record releases of any Mortgages) as necessary or reasonably appropriate to fully and finally release all Liens held by it in favor of the Secured Parties on all Collateral and to otherwise evidence the termination of all Loan

finally release all Liens held by it in favor of the Secured Parties on any part of the Collateral that is sold, assigned, or disposed of as permitted in Section 7.09.

Issuers, and the Lenders under the Loan Documents shall be in addition to all of their other rights and remedies under the Loan Documents and Governmental Requirements, including, without limitation, the Fraudulent Conveyance Act of Delaware, and
nothing in the Loan Documents shall be construed as limiting any such rights or remedies. 
  
 Section 10.04 Confidentiality. 
  
 (a) The Agent, each Issuer and each Lender each agrees that (i) it and its Representatives will keep confidential all non-public information concerning the Borrower or the Partners which 

  

 -85- 

 
is furnished to it by or on behalf of the Borrower, the Partners or any of their respective Representatives (“Confidential Information”)
and, except with the specific prior written consent of the Borrower or as otherwise expressly permitted by the terms of this Section 10.04, will not disclose any Confidential Information, (ii) it and its Representatives will not use Confidential
Information except for the purposes of this Agreement and the Loans, Letters of Credit or other extensions of credit contemplated hereby, (iii) all recipients of Confidential Information will be informed of the confidential nature of the
Confidential Information and instructed not to make use of the Confidential Information in a manner inconsistent herewith, (iv) it and its Representatives will not make available any Confidential Information to other Persons for use or copying and
(v) prior to its disclosure of Confidential Information to any of its Outside Representatives, such Outside Representative shall have executed and delivered a written confidentiality agreement for the Borrower’s benefit substantially in the
form of Exhibit 10.04(c)-3 in respect of the Confidential Information, an executed original of which it will provide promptly to the Borrower. Each of the Agent, each Issuer and each Lender further agrees that in all events (i) the Crude Supply
Agreement and the Supplemental Supply Agreement shall be Confidential Information, (ii) no copies may be made of either such agreement and (iii) any inspection of either such agreement will be restricted to a limited number of its Representatives
and to the premises of the Borrower or the Agent. 
  
 (b) The term
“Confidential Information” does not include information that any Receiving Party can show (i) has become generally available to the public other than as a result of disclosure or other fault by a Receiving Party or its Representatives or
(ii) (A) was already in the possession of a Receiving Party or its Representatives prior to its disclosure to such Person by the Borrower, a Partner or any of their respective Representatives or (B) became available to the Receiving Party or its
Representatives, in each case under this clause (ii), free of any restrictions as to its disclosure and from a source, other than the Borrower, the Partners or any of their respective Representatives, which to the knowledge of the Receiving Party or
the relevant Representative was not then prohibited from transmitting the information to the Receiving Party or its Representatives by a contractual, legal, fiduciary or other obligation. 
  
 (c) Each of the Agent, each Issuer and each Lender also agrees to disclose Confidential Information only to (i) its
Representatives requiring such material for the purpose of administering this Agreement and the transactions contemplated hereby, and (ii) all or any of the Agent, the Issuers, the Lenders, any Prospective Assignees and Prospective Participants;
provided, however, that prior to such disclosure to any Prospective Assignee or Prospective Participant, a Representative of such Prospective Assignee or Prospective Participant shall have executed and delivered a written
confidentiality agreement for the Borrower’s benefit substantially in the form of Exhibit 10.04(c)-1 (in the case of any Prospective Assignee) or Exhibit 10.04(c)-2 (in the case of any Prospective Participant) in respect of the Confidential
Information on behalf of such Eligible Assignee, and prior to such disclosure to any Outside Representative of such Eligible Assignee, such Outside Representative shall have executed and delivered a written confidentiality agreement for the
Borrower’s benefit substantially in the form of Exhibit 10.04(c)-3 in respect of the Confidential Information, and each Lender agrees to provide promptly to the Borrower an executed original of each such confidentiality agreement entered into
by its Prospective Assignee or Prospective Participant, as the case may be, and such Person’s Outside Representative, if any. 
  

 -86- 

 (d) The foregoing will not prohibit the disclosure of any Confidential Information by the Agent, any
Issuer or any Lender if and to the extent that (i) such disclosure may be required by any Governmental Authority having regulatory authority over it, or (ii) it or any of its Representatives may become legally compelled by court order, subpoena or
summons, or by deposition, interrogatory, request for documents or otherwise in connection with Litigation, or by similar legal process, including, without limitation, a civil investigative demand having the same force and effect as a subpoena.
However, in any event described in clause (ii) above, the Agent, each Issuer and each Lender each agrees that it or its Representatives, as the case may be, prior to such disclosure will endeavor in good faith (except to the extent prohibited by any
Governmental Requirement from doing so) to provide the Borrower with prompt notice of such request so that the Borrower may seek an appropriate protective order or other appropriate remedy or waive compliance with the provisions of this Section
10.04(d). In the event that such protective order or other remedy is not obtained, or that the Borrower grants such a waiver hereunder, the Agent, each Issuer and each Lender or its Representatives, as the case may be, will in all events endeavor in
good faith to obtain reliable assurance that confidential treatment will be accorded any Confidential Information so furnished. 
  
 (e) The Agent, each Issuer and each Lender will only be responsible for any breach of this Agreement by it or its Representatives, other than its Outside
Representatives who have executed and delivered a written confidentiality agreement in accordance with this Section 10.04. 
  
 (f) No failure or delay by the Borrower in exercising any right, power or privilege under this Section 10.04 shall operate as a waiver thereof, nor shall
any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege under this Section 10.04. 
  
 Section 10.05 Amendments; Waivers. Any term, covenant, agreement or condition of this Agreement or the Notes may be
amended, and any right thereunder may be waived, if, but only if, such amendment or waiver is in writing and is signed by the Required Lenders and, if the rights and duties of the Agent or an Issuer are affected thereby, by the Agent or such Issuer,
as the case may be, and by the Borrower; provided, however, that no such amendment or waiver shall be effective, unless in writing and signed by each Lender affected thereby, to the extent it (a) changes the several nature or the
amount (except pursuant to Section 2.04) or extends the term of such Lender’s Commitment, (b) reduces the principal of or the rate of interest on the Loans, Reimbursement Obligations or Notes, the amount of such Lender’s participation in
any Letter of Credit or any fees payable pursuant to any Loan Document, (c) postpones any date fixed for, or reduces the amount of, any mandatory payment or prepayment of principal of or interest on the Loans, Notes, Reimbursement Obligations, or
participations in Letters of Credit or any fees payable pursuant to any Loan Document, (d) waives any condition precedent to the initial Loans or Letters of Credit, (e) waives the payment of any amounts payable to any Lender pursuant to Section
3.04, 3.05 or 3.06, (f) waives or amends Section 8.03 or 8.06, this Section 10.05, Section 10.13, or the definition of “Required Lenders”, or (g) releases Collateral with a book value of greater than or equal to $100,000,000, other than as
contemplated in Section 9.10(b)(i). Unless otherwise specified in such waiver, a waiver of any right under any Loan Document shall be effective only in the specific instance and for the specific purpose for which it is given. No election not to
exercise, failure to exercise or delay in exercising any right, nor any course of dealing or performance, shall operate as a waiver of any right of the Agent, any Issuer 

  

 -87- 

 
or any Lender under the Loan Documents or Governmental Requirements, 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 of the Agent, any Issuer or any Lender under the Loan Documents or Governmental Requirements. 
  
 Section 10.06 Assignments and Participations. 
  
 (a) Assignments. Each Lender may from time to time, in accordance with applicable Governmental Requirements, assign any or all of its rights and
obligations under the Loan Documents to one or more Eligible Assignees; provided, however, that no such assignment shall be effective unless and until: (i) the Borrower shall have received prior notice of such assignment; (ii) except
in the case of an assignment to a Lender, (A) with respect to an assignment by a Revolving Lender, the Agent, the Issuers and, so long as no Default shall have occurred and be continuing at the time of effectiveness of such assignment, the Borrower
shall have given their written consent to such assignment (which consent in each case shall not be unreasonably withheld or delayed), and (B) with respect to an assignment by a Term Lender, unless the assignment is to an Approved Fund, the Agent
shall have given its written consent to such assignment (which consent shall not be unreasonably withheld or delayed); (iii) in the case of an assignment by a Revolving Lender, the Agent and the Issuers shall have given their written consent to such
assignment, (iv) except in the case of an assignment to a Lender or an Affiliate of a Lender, the amount of the Term Loan or the amount of the Revolving Commitment of the assigning Lender subject to each such assignment (determined as of the date
the Assignment Agreement respecting such assignment is delivered to the Agent) shall not be less than $1,000,000 with respect to any Term Loan and $5,000,000 with respect to any Revolving Commitment (treating related Approved Funds as one assignee
for purposes of each such minimum); (v) the parties to each such assignment shall have executed and delivered to the Agent an Assignment Agreement (such Assignment Agreement to be (A) electronically executed and delivered to the Agent via an
electronic settlement system then acceptable to the Agent, which shall initially be the settlement system of ClearPar, LLC or (B) manually executed and delivered together with a processing and recordation fee of $3,000; provided that no such
fee shall be payable if the assignment is to an Affiliate of such Lender and only one such fee is payable in connection with simultaneous assignments to or by two or more related Approved Funds), (vi) the assignee, if it shall not be a Lender
immediately prior to the assignment, shall deliver to the Agent an administrative questionnaire and applicable tax form(s). Upon acceptance and recording pursuant to Section 10.06(c), from and after the effective date specified in each Assignment
Agreement, (i) the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment Agreement, have the rights and obligations of a Lender under this Agreement and (ii) the assigning Lender thereunder shall,
to the extent of the interest assigned by such Assignment Agreement, be released from its obligations under this Agreement (and, in the case of an Assignment Agreement covering all or the remaining portion of an assigning Lender’s rights and
obligations under this Agreement, such Lender shall cease to be a party hereto, but shall continue to be entitled to the benefits of Sections 3.04, 3.05, 3.06 and 10.02, as well as to amounts accrued for its account pursuant to Section 2.05 or any
other Loan Document and not yet paid). 
  
 (b)
Maintenance of Register. The Agent shall maintain at one of its offices in The City of New York a copy of each Assignment Agreement delivered to it and a register for the 

  

 -88- 

 
recordation of the names and addresses of the Lenders (including those becoming Lenders pursuant to an Assignment Agreement), and the Commitments of,
principal amount of the Loans owing to and Letter of Credit Obligations of, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive and the Borrower, the Agent,
the Issuers and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available
for inspection by the Borrower, any Issuer and any Lender, at any reasonable time and from time to time upon reasonable prior notice. 
  
 (c) Acceptance and Recordation of Assignments. On its receipt of a duly completed Assignment Agreement executed by an assigning Lender and an
assignee and, to the extent applicable, the assignment fee referred to in Section 10.06(a) above and the written consent of the Agent and the Issuers to such assignment, the Agent shall (i) accept such Assignment Agreement, (ii) record the
information contained therein in the Register and (iii) give prompt notice thereof to the Lenders and the Issuers. No assignment shall be effective unless it has been recorded in the Register as provided in this Section 10.06(c). On acceptance and
recording pursuant to this Section 10.06(c) of any such assignment by a Lender, the Borrower shall, against receipt of the existing Note or Notes, as the case may be, of the assignor Lender, issue a new Note or Notes, as the case may be, to the
assignee Lender and, in the case of a partial assignment, to the assignor Lender, appropriately reflecting such assignment. 
  
 (d) Assignments to Federal Reserve Banks and Others. Nothing in this Section 10.06 shall limit the right of any Lender to assign its interest in
its Loans and Note or Notes, as the case may be, to a Federal Reserve Bank as collateral security under Regulation A of the Board of Governors of the Federal Reserve System, but no such assignment shall release such Lender from its obligations
hereunder. Any Lender which is a fund may pledge all or any portion of its Notes or Loans to its trustee or to a collateral agent or to another creditor providing credit or credit support to such Lender in support of its obligations to such trustee,
such collateral agent or a holder of, or any other representative of a holder of, such obligations, or such other creditor, as the case may be, but no such pledge shall release such Lender from any of its obligations hereunder or substitute any such
pledgee as a Lender. 
  
 (e) Participations. Subject to
Sections 10.04 and 10.06(f), each Lender may from time to time, in accordance with applicable Governmental Requirements, sell or otherwise grant participations in any or all of its rights and obligations under the Loan Documents without the consent
of the Borrower, the Agent, the Issuers or any other Lender; provided, however, that no Lender shall sell any such participation, or permit the resale or transfer of any such participation, to any Person other than a financial
institution meeting the requirement of Eligible Assignee. No sale by a Lender of any participation shall relieve such Lender of any of its obligations hereunder. 
  
 (f) Rights of Participants. Each participation agreement shall provide that the Lender that has sold or granted the
participation shall retain the sole right to take or refrain from taking any action under the Loan Documents, except that such participation agreement may provide that such Lender shall not, without the consent of the participant, agree to any
amendment or waiver that would have the effect of (i) increasing the Commitment of such Lender, (ii) extending the 

  

 -89- 

 
Termination Date, (iii) reducing the principal on the Loans, to the extent that the participant would be affected thereby, (iv) reducing the rate of interest
on the Loans or Notes, to the extent that the participant would be affected thereby or (v) reducing the amount of such Lender’s participation in any fees payable pursuant to Section 2.05, to the extent that the participant would be affected
thereby. All amounts payable to any Lender under Section 3.04, 3.05 or 3.06 shall be determined as if such Lender has not sold any participations. 
  
 (g) Lender Representation. Each Lender party to this Agreement on the Closing Date hereby represents, and each Person that becomes a Lender
pursuant to an Assignment Agreement will represent, and shall be deemed to have represented on becoming a party to this Agreement, that it is in fact, otherwise than by reason of being a Lender, an Eligible Assignee and will make or acquire Loans
hereunder for its own account in the ordinary course of its business.

reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in Section 10.06, any SPC may: (A) with notice to, but
without the prior written consent of, the Borrower and the Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Lender or to any Eligible Assignee (consented to by the Agent)
providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans; and (B) disclose: (I) any Confidential Information on the terms set out in Section 10.04; and (II) on a confidential basis
any other non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC.
