Item 1.01 Entry into a Material Definitive Agreement.

On July 12, 2022, Westlake Chemical OpCo LP (“OpCo”), a subsidiary of Westlake Chemical Partners LP (the “Partnership”), entered into the Second Amendment (the “OpCo Revolver Amendment”) to the Amended and Restated Senior Unsecured Revolving Credit Agreement (as so amended, the “OpCo Revolver”) with a wholly owned subsidiary of Westlake Corporation (together with its subsidiaries other than OpCo and the Partnership, “Westlake”). The OpCo Revolver Amendment, among other things, extends the maturity date to July 12, 2027 and provides for the replacement of London Interbank Offered Rate (“LIBOR”) with Secured Overnight Financing Rate, as administered by the Federal Reserve Bank of New York (“SOFR”). Borrowings under the OpCo Revolver will now bear interest at a variable rate of either (a) SOFR plus the Applicable Margin (as defined in the OpCo Revolver) plus a 0.10% credit spread adjustment or, if SOFR is no longer available, (b) the Alternate Base Rate plus the Applicable Margin minus 1.0%. The Applicable Margin under the OpCo Revolver is 1.75%.

The OpCo Revolver is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference. The foregoing summary does not purport to be complete and is qualified in its entirety by reference to the full text of the OpCo Revolver.

On July 12, 2022, the Partnership entered into the Fourth Amendment (the “MLP Revolver Amendment”) to the Senior Unsecured Revolving Credit Agreement (as so amended, the “MLP Revolver”) with Westlake. The MLP Revolver Amendment, among other things, extends the maturity date to July 12, 2027 and provides for the replacement of LIBOR with SOFR. Borrowings under the MLP Revolver will now bear interest at a variable rate of either (a) SOFR plus the Applicable Margin (as defined in the MLP Revolver) plus a 0.10% credit spread adjustment or, if SOFR is no longer available, (b) the Alternate Base Rate plus the Applicable Margin minus 1.0%. The Applicable Margin under the MLP Revolver varies between 1.75% and 2.75%, depending on the Partnership’s Consolidated Leverage Ratio.

The MLP Revolver is filed as Exhibit 10.2 to this Current Report on Form 8-K and is incorporated herein by reference. The foregoing summary does not purport to be complete and is qualified in its entirety by reference to the full text of the MLP Revolver.

TO

AMENDED AND RESTATED SENIOR UNSECURED REVOLVING CREDIT AGREEMENT

This SECOND AMENDMENT TO AMENDED AND RESTATED SENIOR UNSECURED REVOLVING CREDIT AGREEMENT (this “Amendment”) is made and entered into as of July 12, 2022, by and among WESTLAKE CHEMICAL OPCO LP, a Delaware limited partnership (“Borrower”), as borrower, WESTLAKE POLYMERS LLC, a Delaware limited liability as administrative agent (the “Agent”), and the lenders party thereto (the “Lenders”).

W I T N E S S E T H

WHEREAS, the Borrower, the Agent and the Lenders entered into that certain Amended and Restated Senior Unsecured Revolving Credit Agreement, dated as of June 1, 2017, as amended by the First Amendment thereto, dated as of September 25, 2018 (as so amended, the “Credit Agreement”), pursuant to which the Lenders have made certain financial accommodations available to the Borrower; and

WHEREAS, the Lenders desire to make certain modifications to the Credit Agreement, including to extend the maturity date thereof, as more fully set forth herein.

NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein, and subject to the terms and conditions herein set forth, the parties hereby agree as follows:

DEFINITIONS

Unless otherwise defined herein, including in the text of the preamble and recitals hereto, all capitalized terms used herein shall have the respective meanings given to such terms in Section 1.1 of the Credit Agreement, as amended hereby.

The rules of interpretation set forth in Sections 1.2 and 1.3 of the Credit Agreement shall apply to this Amendment in all respects.

AMENDMENT

Article I of the Credit Agreement is hereby amended by inserting the following defined terms, in each case in their proper alphabetical order:

“ABR Loan” shall mean any Loan bearing interest at a rate determined by reference to the Alternate Base Rate in accordance with the provisions of Section 1.4.

“Alternate Base Rate” shall mean the greater of (a) the rate of interest per annum last quoted by The Wall Street Journal as the “prime rate” for U.S. Dollar loans in the United States for such day (or, if no longer quoted by The Wall Street Journal, such other national publication selected by the Lender in consultation with the Borrower) (the “Prime Rate”), and (b) the Federal Funds Effective Rate plus 0.50% per annum. Any change in the Alternate Base Rate due to a change in the Prime Rate or the Federal Funds Effective Rate shall be effective from and including the date of such change in the Prime Rate or the Federal Funds Effective Rate, respectively.

“Credit Spread Adjustment” shall mean 0.10%.

“Federal Funds Effective Rate” shall mean, for any day, the weighted average (rounded upward, if necessary, to the next 1/100 of 1%) of the rates on overnight Federal funds transactions with members of the Federal Reserve System, as published on the next succeeding Business Day by the Federal Reserve Bank of New York, or, if such rate is not so published for any day which is a Business Day, the average (rounded upward, if necessary, to the next 1/100 of 1%) of the quotations for the day of such transactions received by the Lender from three Federal funds brokers of recognized standing selected by it.

“Prime Rate” shall have the meaning assigned to such term in clause (a) of the definition of “Alternate Base Rate”.

“SOFR” shall mean, a rate equal to the three-month secured overnight financing rate as administered by the SOFR Administrator, in each case as of the date that is two (2) Business Days before the first day of each Interest Period.

“SOFR Administrator” shall mean the Federal Reserve Bank of New York (or a successor administrator of the secured overnight financing rate).

“SOFR Loan” shall mean any Loan bearing interest at a rate determined by reference to SOFR.

“SOFR Scheduled Unavailability Date” shall have the meaning assigned to such term in Section 1.4.

“SOFR Screen Rate” shall have the meaning assigned to such term in Section 1.4.

“SOFR Successor Rate” shall have the meaning assigned to such term in Section 1.4.

“SOFR Successor Rate Conforming Changes” shall mean, with respect to any proposed SOFR Successor Rate, any conforming changes to this Agreement, including changes to Loan Interest Rate, Interest Period, timing and frequency of determining rates and payments of interest and other administrative matters as may be appropriate, in the Lender’s reasonable discretion, to reflect the adoption of such SOFR Successor Rate and to permit its administration in a manner substantially consistent with market practice (or, if the Lender reasonably determines that adoption of any portion of such market practice is not administratively feasible or that no market practice for the administration of such SOFR Successor Rate exists, in such other manner of administration as the Lender reasonably determines in consultation with the Borrower). Such changes shall provide that the SOFR Successor Rate cannot be less than zero for purposes of this Agreement.

Article I of the Credit Agreement is hereby further amended by deleting the defined term “LIBOR”.

Article I of the Credit Agreement is hereby further amended by amending and restating the following defined terms, in each case by deleting the original definition in its entirety and replacing it with the amended definition stated herein:

“Applicable Margin” shall mean 1.75% per annum.

“Loan Interest Rate” shall mean, (a) with respect to any SOFR Loan, SOFR in effect from time to time (as the same may vary from Interest Period to Interest Period) plus the Applicable Margin for the Loan Interest Rate (as set forth in, and determined in accordance with, the definition of “Applicable Margin”) plus the Credit Spread Adjustment, or (b) with respect to any ABR Loan, the Alternate Base Rate plus the Applicable Margin for the Loan Interest Rate (as set forth in, and determined in accordance with, the definition of “Applicable Margin”) minus 1% per annum.

“Maturity Date” shall mean July 12, 2027.

Article I of the Credit Agreement is hereby further amended by inserting the following Section 1.4:

Section 1.4 SOFR Amendment. Notwithstanding anything to the contrary in this Agreement or any other Loan Document, if the Lender or the Borrower determines that:

(a) adequate and reasonable means do not exist for ascertaining SOFR for any applicable interest period because the SOFR quote on the applicable screen page (or other source) used to determine SOFR (“SOFR Screen Rate”) is not available or published on a current basis and such circumstances are unlikely to be temporary;

(b) the administrator of the SOFR Screen Rate or a Governmental Authority having jurisdiction over the Lender has made a public statement identifying a specific date (“SOFR Scheduled Unavailability Date”) after which SOFR or the SOFR Screen Rate will no longer be available or used for determining the interest rate of loans; or

(c) syndicated credit facilities then currently being executed generally, or syndicated credit facilities that include language similar to that contained in this Section are generally being amended to, incorporate or adopt a new benchmark interest rate to replace SOFR;

then, reasonably promptly after such determination, the Lender and the Borrower may amend this Agreement to replace SOFR with an alternate benchmark rate (including any mathematical or other adjustments to the benchmark (if any) incorporated therein), giving due consideration to any evolving or then existing convention for similar Dollar denominated syndicated credit facilities for such alternative benchmarks (“SOFR Successor Rate”), together with any proposed SOFR Successor Rate Conforming Changes and the amendment shall be immediately effective.

If no SOFR Successor Rate has been determined and the circumstances under clause (a) above exist or the SOFR Scheduled Unavailability Date has occurred, the Lender will promptly notify the Borrower. Thereafter, (i) the obligation of the Lender to make or maintain SOFR Loans shall be suspended (to the extent of the affected SOFR Loans or Interest Periods); provided that any request for a Loan by the Borrower thereafter shall be deemed to be a request for an ABR Loan, (ii) the SOFR component shall no longer be used in determining the Loan Interest Rate, and (iii) all outstanding borrowings shall be converted to ABR Loans. Upon receipt of such notice, the Borrower may revoke any pending request for funding of a SOFR Loan (to the extent of the affected SOFR Loans or Interest Periods); provided that if such request is not revoked within 1 Business Day, such request will be deemed to be a request for an ABR Loan.

The first sentence of Section 2.7 of the Credit Agreement is hereby amended and restated as follows:

All computations of interest (a) with respect to any SOFR Loan, shall be made by the Lender on the basis of a year of 360 days, or (b) with respect to any ABR Loan, shall be made by the Lender on the basis of a year of 365 days or 366 days, as the case may be.

EFFECTIVENESS

This Amendment shall become effective upon the execution and delivery of this Amendment by the Borrower and the Lenders.

MISCELLANEOUS

Full Force and Effect. Except as specifically amended hereby, all of the terms and conditions of the Credit Agreement are unaffected and shall continue to be in full force and effect and shall be binding on the parties hereto in accordance with their respective terms. Each reference to the Credit Agreement therein or in any other agreement, document or instrument executed and delivered pursuant to the Credit Agreement shall mean and constitute a reference to the Credit Agreement as amended hereby. Except as specifically set forth in this Amendment, nothing in this Amendment shall be construed as modifying any other term or condition of the Credit Agreement or operate as a waiver of, or in prejudice to, any right, power or remedy of the Lender under the Credit Agreement, any applicable law or any existing or future Default or Event of Default.

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

Counterparts. This Amendment may be executed in any number of counterparts, each of which shall be enforceable against the party executing such counterpart, and all of which together shall constitute one instrument. Each counterpart may be delivered in original, facsimile or electronic (e.g., “.pdf”) form.
