shall include the feminine and masculine wherever appropriate. 
 The sale of the Securities to the Initial Purchaser will be made without
registration of the Securities under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the “Securities Act”), in reliance upon exemptions from the registration requirements of the Securities Act.

 In connection with the sale of the Securities, the Company has prepared a preliminary offering memorandum, dated October 9, 2021 (as
amended or supplemented at the date thereof, including any and all exhibits thereto and any information incorporated by reference therein, the “Preliminary Memorandum”), and a final offering memorandum, dated October 12, 2021 (as
amended or supplemented at the Execution Time (as defined below), including any and all exhibits thereto and any information incorporated by reference therein, the “Final Memorandum”). Each of the Preliminary Memorandum and the Final
Memorandum sets forth certain information concerning the Company and the Securities. The Company hereby confirms that it has authorized the use of the Disclosure Package (as defined below), the Preliminary Memorandum and the Final Memorandum, and
any amendment or supplement thereto, in connection with the offer and sale of the Securities by the Initial Purchaser. Unless stated to the contrary, any references herein to the terms “amend”, “amendment” or
“supplement” with respect to the Disclosure Package, the Preliminary Memorandum and the Final Memorandum shall be deemed to refer to and include any information filed under the Exchange Act (as defined below) subsequent to the Execution

Preliminary Memorandum, as amended or supplemented at the date and time that this Agreement is executed and delivered by the parties hereto (the “Execution Time”), (ii) the final term sheet prepared pursuant to Section 5(b) hereto and
in the form attached as Schedule II hereto and (iii) any writings in addition to the Preliminary Memorandum that the parties expressly agree in writing to treat as part of the Disclosure Package (“Issuer Written Information”). 

The net proceeds from the offering of the Securities will be used to repurchase outstanding shares of common stock, par value $0.01 per
share, of the Company (“Common Stock”). Pending the execution of share repurchases, the Company intends to invest the proceeds from the offering in cash and/or invest in short- and long-term marketable securities.

provided, however, that prior to the completion of the distribution of the Securities by the Initial Purchaser (as defined by the opinion of counsel (including internal counsel) to the Initial Purchaser), the Company shall ensure that
no document be filed under the Exchange Act that is incorporated by reference in the Disclosure Package or the Final Memorandum unless, prior to such proposed filing, the Company has provided the Initial Purchaser with a copy of such document for
their review and the Initial Purchaser has not reasonably objected to the filing of such document. The Company will promptly advise the Initial Purchaser when any document filed under the Exchange Act that is incorporated by reference in the
Disclosure Package of the Final Memorandum shall have been filed with the Securities and Exchange Commission (the “Commission”). 

(d) If at any time prior to the completion of the sale of the Securities by the Initial Purchaser, any event occurs as a result of which the
Disclosure Package or the Final Memorandum, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under

 (f) The Company will arrange, if necessary, for the qualification
of the Securities for sale by the Initial Purchaser under the laws of such jurisdictions as the Initial Purchaser may designate (including certain provinces of Canada) and will maintain such qualifications in effect so long as required for the sale
of the Securities; provided that in no event shall the Company be obligated to (i) qualify to do business in any jurisdiction where it is not now so qualified, (ii) subject itself to taxation in any jurisdiction where it is not
presently so subject or (iii) take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject. The Company will
promptly advise the Initial Purchaser of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such
purpose. 
 (g) The Company will not, and will not permit any of its Affiliates to, resell any Securities that have been acquired by any of

General Solicitation with respect to the offer or sale of the Securities, other than any General Solicitation in respect of which the Initial Purchaser has given its prior written consent; provided that the prior written consent of the
Initial Purchaser shall be deemed to have been given in respect of the General Solicitation included in Schedule III hereto. 
 (k) For so
long as any of the Securities are outstanding and are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, the Company, during any period in which it is not subject to and in compliance with
Section 13 or 15(d) of the Exchange Act, will provide to each holder of such restricted securities and to each prospective purchaser (as designated by such holder) of such restricted securities, upon the request of such holder or prospective
purchaser, any information required to be provided by Rule 144A(d)(4) under the Securities Act. This covenant is intended to be for the benefit of the holders, and the prospective purchasers designated by such holders, from time to time of such

exchangeable for the Series A Preferred Shares or such other securities), other than pursuant to the offering. 
 (p) The Company will not
take, directly or indirectly, any action designed to, or that has constituted or that might reasonably be expected to, cause or result, under the Exchange Act or otherwise, in stabilization or manipulation of the price of any security of the Company
to facilitate the sale or resale of the Securities. 
 (q) So long as any of the Securities are outstanding, the Company will, furnish at its
expense to the Initial Purchaser and, upon request, to the holders of the Securities and prospective purchasers of the Securities, the information required by Rule 144A(d)(4) under the Securities Act (if any). 

(r) The Company shall comply with all applicable securities and other laws, rules and regulations, including, without limitation, the
Sarbanes-Oxley Act, and shall cause its directors and officers, in their respective capacities as such, to comply with such laws, rules and regulations, including, without limitation, the provisions of the Sarbanes-Oxley Act. 

(s) The Company will apply the net proceeds from the sale of the Securities to be sold by it in the offering hereunder substantially in
accordance with the description set forth in the Disclosure Package and the Final Memorandum under the caption “Use of Proceeds.”

6. Conditions to the Obligations of the Initial Purchaser. The obligations of the Initial Purchaser to purchase the Securities shall be
subject to the accuracy of the representations and warranties of the Company contained herein at the Execution Time and the Closing Date, to the accuracy of the statements of the Company made in any certificates delivered pursuant to the provisions
hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions:

as the Initial Purchaser may reasonably require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters. 

(d) The Company shall have furnished to the Initial Purchaser a certificate of the Company, signed by (x) the chief executive officer of
the Company and (y) the principal financial or accounting officer of the Company, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Disclosure Package and the Final Memorandum and any
supplements or amendments thereto and this Agreement and that: 

  
 -17- 












 (i) the representations and warranties of the Company in this Agreement are
true and correct on and as of the Closing Date with the same effect as if made on the Closing Date, and the Company have complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied hereunder at or prior
to the Closing Date; and 
 (ii) since the date of the most recent financial statements included in the Disclosure Package
and the Final Memorandum (exclusive of any amendment or supplement thereto), there has been no material adverse change in the condition (financial or otherwise), prospects, business or properties of the Company and its subsidiaries, taken as a
whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto), the effect
of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Initial Purchaser, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Securities as
contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto). 
 (g) The Securities
shall be eligible for clearance and settlement through The Depository Trust Company.

 7. Reimbursement of Expenses.
If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchaser set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof
or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by the Initial Purchaser, the Company will reimburse the Initial
Purchaser on demand for all reasonable and documented expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities. 

8. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless the Initial Purchaser, the directors,
officers, employees, Affiliates and agents of the Initial Purchaser and each person who controls the Initial Purchaser within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities,
joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or
liabilities or actions in respect thereof arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Final Memorandum, any Issuer Written Information, any General
Solicitation, any document listed on Schedule IV hereto or any other written information used by or on behalf of the Company in connection with the offer or sale of the Securities, or in any amendment or supplement thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact required to be stated therein or 

  
 -19- 












 
necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any
legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent
that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Memorandum, the Final Memorandum, or in any amendment thereof
or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Initial Purchaser through the Initial Purchaser specifically for inclusion therein. This indemnity agreement will be
in addition to any liability that the Company may otherwise have. 
 (b) The Initial Purchaser agrees to indemnify and hold harmless the
Company and its directors and officers, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity to the Initial Purchaser, but only with reference to
written information relating to the Initial Purchaser furnished to the Company by or on behalf of the Initial Purchaser specifically for inclusion in the Preliminary Memorandum or the Final Memorandum (or in any amendment or supplement thereto).
This indemnity agreement will be in addition to any liability that the Initial Purchaser may otherwise have. The Company acknowledges that (i) the statements set forth in the last paragraph of the cover page regarding delivery of the
Securities and (ii) under the heading “Plan of Distribution”, the eighth and ninth paragraphs related to covering and stabilizing transactions in the Preliminary Memorandum and the Final Memorandum constitute the only
information furnished in writing by or on behalf of the Initial Purchaser for inclusion in the Preliminary Memorandum or the Final Memorandum or in any amendment or supplement thereto. 

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified
party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will
not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and
(ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to
appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party
shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided,
however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the
indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the
indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or 

  
 -20- 












 
potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded upon the advice of
counsel that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel
reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened
claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or
consent: (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a
failure to act, by or on behalf of any indemnified party. 
 (d) In the event that the indemnity provided in paragraph (a) or
(b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Initial Purchaser agree to contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, damage, liability or action) (collectively “Losses”) to which the Company and the Initial Purchaser may be subject in such
proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and by the Initial Purchaser, on the other, from the offering of the Securities. If the allocation provided by the immediately preceding sentence
is unavailable for any reason, the Company and the Initial Purchaser shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, on the one hand, and the Initial
Purchaser, on the other, in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from
the offering (before deducting expenses) received by the Company, and benefits received by the Initial Purchaser shall be deemed to be equal to the total purchase discounts and commissions set forth in this Agreement. Relative fault shall be
determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company, on the one hand, or the
Initial Purchaser, on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Initial Purchaser agree that it would not be
just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), in no
event shall the Initial Purchaser be required to contribute any amount in excess of the amount by which the total purchase discounts and commissions received by the Initial Purchaser with respect to the offering of the Securities exceeds the amount
of any damages that the Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from 

  
 -21- 












 
any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls the Initial Purchaser within the meaning of either the Securities
Act or the Exchange Act and each director, officer, employee, Affiliate and agent of the Initial Purchaser shall have the same rights to contribution as the Initial Purchaser, and each person who controls the Company within the meaning of either the
Securities Act or the Exchange Act and each officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d). 

9. Termination. This Agreement shall be subject to termination in the absolute discretion of the Initial Purchaser, by notice given to
the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading of the Common Stock shall have been suspended on the New York Stock Exchange or any other United States national securities exchange;
(ii) trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such exchange; (iii) a banking moratorium shall have been declared either by U.S.
federal or New York State authorities; (iv) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services; or (v) there shall have occurred any outbreak or escalation of
hostilities, declaration by the United States of a national emergency or war or other calamity or crisis, in each case, the effect of which on financial markets is such as to make it, in the sole judgment of the Initial Purchaser impractical or
inadvisable to proceed with the offering, sale or delivery of the Securities as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto). 

10. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements
of the Company and its officers and of the Initial Purchaser set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Initial Purchaser or the Company or any of
the indemnified persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement. 

11. Notices. All communications hereunder will be in writing and effective only on receipt. Notices to the Initial Purchaser shall be
given to Goldman Sachs & Co. LLC, 200 West Street, New York, New York 10282, Attention: Registration Department. Notices to the Company, will be mailed, delivered or telefaxed to 972-556-6119 and confirmed to it at 6555 Sierra Drive, Irving, Texas 75039, attention of the Legal Department. 

12. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and
the indemnified persons referred to in Section 8 hereof and their respective successors, and, except as expressly set forth in Section 5(k) hereof, no other person will have any right or obligation hereunder. 

13. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the
Initial Purchaser, or any of them, with respect to the subject matter hereof. 

  
 -22- 












 14. Applicable Law. This Agreement, and any claim, controversy or dispute arising
under or related to this Agreement, will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

 EXHIBIT A-1 

OPINION AND DISCLOSURE LETTER OF 

SIDLEY AUSTIN LLP 











 Based on and subject to the foregoing and the other limitations, qualifications, exceptions
and assumptions set forth herein, we are of the opinion that: 
 (i) The Company is a corporation validly existing and in
good standing under the laws of the State of Delaware. The Company has the corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Disclosure Package (as defined below) and the Offering
Memorandum and to execute, deliver and perform its obligations under the Purchase Agreement. 
 The Purchase Agreement has
been duly authorized, executed and delivered by the Company. 
 The Shares have been duly authorized by the Company and, when
issued and paid for in accordance with the Purchase Agreement, will be validly issued, fully paid and nonassessable, and the issuance of such Shares is not subject to preemptive rights of any security holder of the Company arising by operation of
the DGCL as currently in effect or by operation of the restated certificate or bylaws of the Company as currently in effect. 

No consent, approval, authorization or other order of any federal regulatory body, federal administrative agency or other
federal governmental body of the United States of America under Applicable Laws for the execution and delivery by the Company of the Purchase Agreement, as applicable, and the offer and sale of the Shares to the Initial Purchaser as contemplated by
the Purchase Agreement. 
 The execution and delivery by the Company of the Purchase Agreement, and the offer and sale of the
Shares to the Initial Purchaser pursuant to the Purchase Agreement, do not (a) violate the restated certificate or bylaws of the Company, (b) result in any breach of, or constitute a default under, any of the agreements or instruments
listed on Schedule I hereto or (c) result in a violation by the Company of any of the terms and provisions of any Applicable Laws. 

The statements in the Preliminary Offering Memorandum and the Offering Memorandum under the caption “Description of Series
A Preferred Shares,” to the extent that such statements purport to describe certain provisions of the Company’s restated certificate or the Certificate of Designations, accurately describe such provisions in all material respects. 

Assuming (A) the accuracy and performance of, and compliance with, the representations, warranties and agreements of the
Company and the Initial Purchaser set forth in the Purchase Agreement and (B) the accuracy and performance of, and compliance with, the representations, warranties and agreements of each of the persons to whom the Initial Purchaser initially
offers, resells or otherwise transfers the Shares as set forth in the Offering Memorandum under the caption “Notice to Investors,” it is not necessary, in connection with the sale of the Shares to the Initial Purchaser under the
Purchase Agreement or in connection with the initial resale of the Shares by the Initial Purchaser, in each case in the manner contemplated by the Purchase Agreement and the Offering Memorandum, to register the Shares under the 1933 Act, it being
understood that we express no opinion as to any subsequent resale or other transfer of any Shares. 











 The Company is not and, after giving effect to the offering and sale of the
Shares and the application of the proceeds thereof as described in the Offering Memorandum, will not be required to be registered as an “investment company” as defined in the 1940 Act. 











 EXHIBIT A-2 

OPINION OF 

VINSON & ELKINS LLP 











 Based on such facts and subject to the qualifications, assumptions and limitations set forth
herein and in the Preliminary Memorandum and Final Memorandum, we hereby confirm that the statements in the Preliminary Memorandum and Final Memorandum under the caption “Certain United States Federal Income Tax Considerations,” insofar as
such statements purport to constitute summaries of United States federal income tax law and regulations or legal conclusions with respect thereto, have been reviewed by us and are accurate in all material respects. 











 EXHIBIT B 

OPINION OF VISTRA CORP. 

GENERAL COUNSEL 











 Based on and subject to the foregoing and the other limitations, qualifications, exceptions
and assumptions set forth herein, I am of the opinion that the Company has an authorized capitalization as set forth in the Preliminary Offering Memorandum and the Offering Memorandum under the heading “Capitalization” and all of the
outstanding shares of capital stock or other equity interests of each of the Company’s subsidiaries have been duly and validly authorized and issued and, in the case of capital stock, are fully paid and
non-assessable. I am also of the opinion that there is no pending or, to my knowledge, threatened action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator
involving the Company or any of its subsidiaries or its or their property that is not adequately disclosed in the Preliminary Offering Memorandum and Offering Memorandum, except in each case for such proceedings that, if the subject of an
unfavorable decision, ruling or finding would not singly or in the aggregate, have a Material Adverse Effect as such term is defined in the Purchase Agreement.
