	3)	In connection with the Upgradation, Salix and Glenmark are, simultaneously with their entry into this Agreement, amending and restating the Supply Agreement to reflect
new and amended terms upon which Glenmark will supply Compound to Salix (the “Amendment and Restatement”); 

  

	4)	The Upgradation at the new facility is specifically for the manufacture of Compound which will be manufactured by Glenmark, to the extent of Salix’s requirements,
exclusively for Salix; 

  

	5)	In view of the substantial investments being made by Glenmark towards the Upgradation [*] the Compound and/or product containing the Compound as an active ingredient

and undertakes to procure from Glenmark, in accordance with and subject to the terms and provisions of the Amendment and Restatement, such amounts of Compound as are contemplated by Section 2.1(b) of the Amendment and Restatement.

  

	3.	Salix further agrees to pay Glenmark, within [*] ([*]) days of signing of this Agreement, an amount of fifteen million United States dollars ($15,000,000) as an advance

	4.	The Advance shall be charged by Glenmark to the extent of three million United States dollars ($3,000,000) on each of the first through fifth anniversaries of the date
of this Agreement to reduce the amount of the installment then required to be paid by Salix in respect of the Commitment Fee under Section 2.8(e) of the Amendment and Restatement, such that on the fifth anniversary of the date of this Agreement

 [*] Confidential treatment requested. 

  
 2 

	5.	Glenmark shall use commercially reasonable efforts to perform the Upgradation. In the event that the Parties agree that Glenmark has failed to undertake commercially
reasonable efforts to perform the Upgradation within a period of [*] from the date of this Agreement, or any further extension mutually agreed by the Parties, then the Parties will work towards remedying/curing the situation. In the event that any
failure by Glenmark to use commercially reasonable efforts to perform the Upgradation has not been remedied/cured in a reasonable time, then Salix shall be entitled to a return of the Advance minus the amounts spent by Glenmark up to that time in
the Upgradation. Should the Parties be unable to agree whether Glenmark has undertaken commercially reasonable efforts to perform the Upgradation and/or whether the situation has been remedied/cured in a reasonable time, then either Party may bring
an action to resolve the dispute in accordance with Section 9.7 of the Amendment and Restatement. 

  

	6.	In the event that Salix terminates the Amendment and Restatement other than pursuant to Section 7.2(c)(i) thereof or Glenmark terminates the Amendment and
Restatement pursuant to Section 7.2(c)(i) thereof, then the balance of the Advance then lying with Glenmark shall stand forfeited. 

  

	7.	It is clarified that the Commitment Fee shall be exclusive and in addition to the Purchase Price (as defined in the Amendment and Restatement) payable by Salix to
Glenmark under the Amendment and Restatement for the Compound supplied by Glenmark to Salix. 

  

	8.	The Parties agree that Sections 3, 4, 5, and 6 of this Agreement shall govern in the event of a conflict between the provisions of this Agreement and any provision in
the Amendment and Restatement. 

  

	9.	Recitals hereinabove shall constitute an integral part of this Agreement. 

  

	10.	Neither of the Parties hereto may assign this Agreement or any of its rights and obligations hereunder except in connection with an assignment of the Amendment and
Restatement pursuant to Section 9.10 thereof. 

  

	11.	No failure or delay on the part of a Party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of
any right or remedy hereunder preclude any other or a future exercise thereof or the exercise of any other right or remedy granted hereby or by law. 

  

	12.	If any provision of this Agreement is held to be invalid or unenforceable for any reason, it shall be adjusted rather than voided, if possible, in order to achieve the
intent of the Parties to the fullest extent possible. In any event, all other provisions of this Agreement shall be deemed valid and enforceable to the fullest extent possible. 

 

	13.	This Agreement, together with the Amendment and Restatement, constitutes the entire agreement and understanding between the Parties concerning the subject matter hereof
and supersedes all prior discussions, agreements and negotiations between them as to the subject matter hereof.

 NOW, THEREFORE, for and in consideration of the mutual covenants and
agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged and confessed, Borrower, the Guarantors, Administrative Agent and the Lenders hereby agree as follows: 

SECTION 1. Amendments to Credit Agreement. Subject to the satisfaction or waiver in writing of each condition precedent set forth in
Section 4 hereof, and in reliance on the representations, warranties, covenants and agreements contained in this Amendment, the Credit Agreement shall be amended in the manner provided in this Section 1.

hereby are amended and restated in their respective entireties to read as follows: 
 “Aggregate
Commitment” means, at any time, the sum of the Commitments of all the Lenders at such time, as such amount may be reduced or increased from time to time pursuant to Section 2.02 or Section 2.03; provided that such amount

 1.3 Schedules. Schedule 2.01 of the Credit Agreement shall be and it hereby is amended and
restated in its entirety and replaced with Schedule 2.01 attached hereto. 
 SECTION 2. Redetermined Borrowing Base.
This Amendment shall constitute notice of a Scheduled Redetermination of the Borrowing Base pursuant to Section 3.04 of the Credit Agreement, and Administrative Agent, the Lenders, Borrower and the Guarantors hereby acknowledge that
effective as of the date of this Amendment, the Borrowing Base is $1,600,000,000 and such redetermined Borrowing Base shall remain in effect until the earlier of (a) the next Redetermination of the Borrowing Base or (b) the date such
Borrowing Base is otherwise reduced pursuant to the terms of the Credit Agreement. 
 SECTION 3. New Lenders, Departing Lenders and
Reallocation and Increase of Commitments. The Lenders have agreed among themselves to reallocate their respective Commitments, and to, among other things, (a) permit one or more of the Lenders to increase their respective Commitments
under the Credit Agreement (each, an “Increasing Lender”), and (b) allow certain financial institutions identified by J.P. Morgan Securities LLC (“J.P. Morgan”), in its capacity as a Co-Lead Arranger, in
consultation with Borrower, to become a party to the Credit Agreement as a Lender (each, a “New Lender”) by acquiring an interest in the Aggregate Commitment. In addition, The Royal Bank of Scotland plc (the “Departing
Lender”) desires to assign all of its rights and obligations as a Lender under the Credit Agreement to the other Lenders and to no longer be a party to the Credit Agreement. Each of Administrative Agent and Borrower hereby consent to

respect to such reallocation. Administrative Agent hereby waives the $3,500 processing and recordation fee set forth in Section 11.04(b)(ii)(C) of the Credit Agreement with respect to the assignments and reallocations contemplated by this
Section 3. The increase in each Increasing Lender’s Commitment and the acquisition by each New Lender of an interest in the Aggregate Commitment shall be deemed to have been consummated pursuant to the terms of the Lender
Certificate attached as Exhibit F to the Credit Agreement as if such Increasing Lender or New Lender, as the case may be, had executed a Lender Certificate with respect to such increase or acquisition. To the extent requested by any Lender,
including the Departing Lender, and in accordance with Section 2.17 of the Credit Agreement, Borrower shall pay to such Lender, within the time period prescribed by Section 2.17 of the Credit Agreement, any amounts required to be paid by
Borrower under Section 2.17 of the Credit Agreement in the event the payment of any principal of any Eurodollar Loan or the conversion of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto is required in
