“Initial Purchasers”), for whom you (the “Representative”) are acting as representative, $400,000,000 principal amount of its 9.250% Senior Notes due 2026 (the “Notes”). 

The Securities (as defined below) are to be issued under an indenture (the “Initial Indenture”), to be dated as of August 10,
2021, between the Escrow Issuer and Citibank, N.A., as trustee (the “Trustee”). On the Effective Date (as defined below), (i) Penn Virginia Holdings, LLC, a limited liability company organized under the laws of Delaware (the
“Company”) and an indirect, wholly owned subsidiary of Penn Virginia Corporation, a Virginia corporation (the “Parent”), will merge with the Escrow Issuer, with the Company surviving and assuming the obligations of the Escrow
Issuer under the Initial Indenture, (ii) the Company, the Guarantors (as defined below) and the Trustee will enter into a supplemental indenture (the “Supplemental Indenture”) pursuant to which the Guarantors will fully and
unconditionally guarantee obligations under the Notes and the Indenture and (iii) the Company will succeed to the Escrow Issuer’s obligations under the Notes and the Initial Indenture by operation of law. To the extent there are no
additional parties listed on Schedule I other than you, the term “Representative” as used herein shall mean you as the Initial Purchasers, and the terms “Representative” and “Initial Purchasers” shall mean either
the singular or plural as the context requires. The use of the neuter in this purchase agreement (this “Agreement”) shall include the feminine and masculine wherever appropriate. 

 For the purposes of this Agreement, the term (a) “Indenture” shall mean

entities identified on Schedule IV hereto; (c) “Lonestar Guarantors” shall mean each of Lonestar Resources US Inc., a Delaware corporation (“Lonestar”), and its subsidiaries required to become guarantors of the Notes in
accordance with the provisions of the Indenture upon the consummation of the Acquisition (as defined below); and (d) “Guarantors” shall mean all of the Company Guarantors and the Lonestar Guarantors. 

The Notes will be fully and unconditionally guaranteed on a senior unsecured basis (the “Guarantees” and, together with the Notes,
the “Securities”) as to the payment of principal and interest jointly and severally by the Guarantors as of and from the Effective Date. The Escrow Issuer, the Company and the Guarantors are herein collectively referred to as the
“Penn Virginia Parties.” 
 The sale of the Securities to the Initial Purchasers 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. 

Pursuant to the agreement and plan of merger (together with all exhibits, annexes, schedules and other disclosure letters thereto,
collectively, as modified, amended, supplemented, consented to or waived, the “Merger Agreement”) dated as of July 10, 2021, as may be amended from time to time, by and between Parent and Lonestar, Upsilon Merger Sub Inc., a wholly
owned, direct subsidiary of the Company, will merge with and into Lonestar, with Lonestar continuing as the surviving corporation, which merger will immediately be followed by the merger of Lonestar with and into Penn Virginia Merger Sub LLC, a
wholly owned, direct subsidiary of Holdings, with Penn Virginia Merger Sub LLC continuing as the surviving entity (the “Acquisition”). 

Subject to the last sentence of this paragraph, on the Closing Date (as defined below), the Escrow Issuer will enter into an escrow agreement,
dated as of the Closing Date (the “Escrow Agreement”), among the Escrow Issuer, Citibank, N.A., as escrow agent (in such capacity, the “Escrow Agent”) and the Trustee, in connection with the gross proceeds of the Notes offering
and an additional amount in an aggregate amount sufficient to fund a special mandatory redemption of the Notes being deposited into an escrow account (the “Escrow Account”) held by the Escrow Agent. If (i) the Acquisition has not been
completed on or prior to November 26, 2021 (the “Outside Date”) or (ii) at any time prior to the Outside Date, the Merger Agreement has been validly terminated (or the Company has decided that it will not pursue the consummation
of the Acquisition or that the consummation of the Acquisition cannot or is not reasonably likely to be satisfied by such date), the Company will be required to redeem all of the Notes at a redemption price (the “Special Mandatory Redemption
Price”) equal to 100% of the principal amount of the notes, plus accrued and unpaid interest to, but excluding, the special mandatory redemption date (the “Special Mandatory Redemption”), in accordance with the terms of the Indenture.
If all of the conditions set forth in the Escrow Agreement are satisfied on or prior to the Outside Date, the funds held in the Escrow Account will be released to, or at the order of the Escrow Issuer released to, the Company, other than the portion
of such

Acquisition being referred to herein as the “Effective Date”), in accordance with the terms of the Escrow Agreement.

individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to have a Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum
(exclusive of any amendment or supplement thereto). 
 (ff)    All royalties, rentals, deposits and other amounts owed
under the oil and gas leases constituting the oil and gas properties of the Escrow Issuer, the Company and their respective subsidiaries have been properly and timely paid (other than amounts held in suspense accounts pending routine payments or
related to disputes about the proper identification of royalty owners), except in any such case, where the failure to properly or timely pay such amounts would not reasonably be expected to have a Material Adverse Effect. No material amount of
proceeds from the sale or production attributable to the oil and gas properties of the Escrow Issuer, the Company and their respective subsidiaries are currently being held in suspense by any purchaser thereof, except where such amounts due would
not reasonably be expected to have a Material Adverse Effect. 

  
 11 

 (gg)    Except as disclosed in the Disclosure Package and the Final
Memorandum, the Escrow Issuer, the Company and each of their respective subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with
management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability; (iii) access to assets is
permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to
any differences. Since the date of the latest audited financial statements included in the Disclosure Package and the Final Memorandum, the Escrow Issuer’s, the Company’s and their respective subsidiaries’ internal controls
over financial reporting are effective and the Escrow Issuer, the Company and their respective subsidiaries are not aware of any material weakness in their internal control over financial reporting. 

(hh)    The Escrow Issuer, the Company and their respective subsidiaries are (i) in compliance with any and all
applicable laws and regulations relating to the protection of human health and safety (as it relates to human exposure to hazardous or toxic substances or wastes, pollutants or contaminants), the environment or hazardous or toxic substances or
wastes, pollutants or contaminants (“Environmental Laws”); (ii) have received and are in compliance with all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses;
and (iii) have not received notice of any actual or potential liability under any Environmental Law, except where such non-compliance with Environmental Laws, failure to receive required permits, licenses
or other approvals, or liability would not, individually or in the aggregate, have a Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement
thereto). Except as set forth in the Disclosure Package and the Final Memorandum, or with respect to which the Company does not reasonably expect to incur or be subject to any material liability, none of the Escrow Issuer, the Company or any of
their respective subsidiaries has been named as a “potentially responsible party” under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended. 

(ii)     In the ordinary course of its business, the Penn Virginia Parties and their respective subsidiaries
periodically review the effect of applicable Environmental Laws on the business, operations and properties of the Escrow Issuer, the Company and their respective subsidiaries, in the course of which it identifies and evaluates associated costs and
liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with applicable Environmental Laws, or any permit, license or
approval required under Environmental Laws, any related constraints on operating activities and any potential liabilities to third parties); on the basis of such review, the Penn Virginia Parties and their respective subsidiaries reasonably
concluded that such associated costs and liabilities would not, individually or in the aggregate, have a Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment
or supplement thereto). 
 (jj)    Except as would not reasonably be expected to have a Material Adverse Effect,
(i) the minimum funding standard under Section 302 of the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder 

  
 12 

 
(“ERISA”), has been satisfied by each “pension plan” (as defined in Section 3(2) of ERISA) which has been established or maintained by the Company and/or one or more of
its subsidiaries that is subject to such minimum funding standards, and the trust forming part of each such plan which is intended to be qualified under Section 401 of the Internal Revenue Code of 1986, as amended, and the regulations
promulgated thereunder is so qualified; (ii) each of the Escrow Issuer, the Company and their respective subsidiaries has fulfilled its obligations, if any, under Section 515 of ERISA; (iii) none of the Escrow Issuer, the Company or
any of their respective subsidiaries maintains or is required to contribute to a “welfare plan” (as defined in Section 3(1) of ERISA) which provides retiree or other post-employment welfare benefits or insurance coverage (other than
“continuation coverage” (as defined in Section 602 of ERISA) or severance benefits); (iv) each pension plan and welfare plan established or maintained by the Company and/or one or more of its subsidiaries is in compliance in all
material respects with the currently applicable provisions of ERISA; and (v) none of the Escrow Issuer, the Company or any of their respective subsidiaries has incurred or could reasonably be expected to incur any withdrawal liability under
Section 4201 of ERISA, any liability under Section 4062, 4063, or 4064 of ERISA, or any other liability under Title IV of ERISA. 

(kk)    The operations of the Escrow Issuer, the Company and their respective subsidiaries are and have been conducted at
all times in compliance with applicable financial recordkeeping and reporting requirements and the money laundering statutes and the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered
or enforced by any governmental agency (collectively, the “Money Laundering Laws”), and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Escrow Issuer, the
Company or any of their respective subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Escrow Issuer, the Company and the Guarantors, threatened. 

(ll)    None of the Escrow Issuer, the Company or any of their respective subsidiaries nor, to the knowledge of the Escrow
Issuer, the Company and the Guarantors, any director, officer, agent, employee or Affiliate or any of its subsidiaries (i) is, or is controlled or 50% or more owned in the aggregate by or is acting on behalf of, one or more individuals or
entities that are currently the subject of any sanctions administered or enforced by the United States (including any administered or enforced by the Office of Foreign Assets Control of the U.S. Department of the Treasury, the U.S. Department of
State or the Bureau of Industry and Security of the U.S. Department of Commerce), the United Nations Security Council, the European Union, a member state of the European Union (including sanctions administered or enforced by Her Majesty’s

resident in a country or territory that is, or whose government is, the subject of Sanctions that broadly prohibit dealings with that country or territory (collectively, “Sanctioned Countries” and each, a “Sanctioned Country”) or
(iii) will, directly or indirectly, use the proceeds of this offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other individual or entity in any manner (x) to fund or
facilitate any activities of or business with any individual or entity that, at the time of such funding or facilitation, is the subject or target of Sanctions, or is in a Sanctioned Country or (y) that would result in a violation of any
Sanctions by, or could result in the imposition of Sanctions against, any individual or entity (including any individual or entity 

  
 13 

 
participating in the offering, whether as underwriter, initial purchaser, advisor, investor or otherwise); provided, however, that none of the Penn Virginia Parties makes any
representation hereunder as to the ultimate uses of cash that may be made by any lender under the Company’s revolving credit facility or secured term loan or Lonestar’s revolving credit facility or secured term loan that receives payment
from the Company as described in the Disclosure Package and the Final Memorandum under the heading “Use of Proceeds.” 

(mm)    None of the Escrow Issuer, the Company or any of their respective subsidiaries has engaged in any dealings or
transactions with or for the benefit of a Sanctioned Person, or with or in a Sanctioned Country, in the preceding three years, nor does the Escrow Issuer, the Company or any of their respective subsidiaries have any plans to engage in dealings or
transactions with or for the benefit of a Sanctioned Person, or with or in a Sanctioned Country.  
 (nn)    None
of the Escrow Issuer, the Company or any of their respective subsidiaries nor, to the knowledge of the Escrow Issuer, the Company and the Guarantors, any director, officer, agent, employee, Affiliate or other person acting on behalf of the Escrow
Issuer, the Company or any of their respective subsidiaries is aware of or has taken any action, directly or indirectly, that could result in a violation or a sanction for violation by such persons of the Foreign Corrupt Practices Act of 1977 or the
U.K. Bribery Act 2010, each as may be amended, or similar law of any other relevant jurisdiction, or the rules or regulations thereunder; and the Escrow Issuer, the Company and their respective subsidiaries have instituted and maintain policies and
procedures to ensure compliance therewith. No part of the proceeds of the offering will be used, directly or indirectly, in violation of the Foreign Corrupt Practices Act of 1977 or the U.K. Bribery Act 2010, each as may be amended, or similar law
of any other relevant jurisdiction, or the rules or regulations thereunder; provided, however, that none of the Penn Virginia Parties makes any representation hereunder as to the ultimate uses of cash that may be made by any lender
under the Company’s revolving credit facility or secured term loan or Lonestar’s revolving credit facility or secured term loan that receives payment from the Company as described in the Disclosure Package and the Final Memorandum under
the heading “Use of Proceeds.” 
 (oo)     Except as disclosed in the Preliminary Memorandum and the
Final Memorandum, the Company (i) does not have any material lending or other relationship with any Initial Purchaser or Affiliate of any Initial Purchaser and (ii) does not intend to use any of the proceeds from the sale of the Securities
hereunder to repay any outstanding debt owed to any Affiliate of any Initial Purchaser. 
 (pp)    Each of the Escrow
Issuer, the Company and the Guarantors is, and immediately after the Closing Date will be, Solvent. As used herein, the term “Solvent” means, with respect to any person on a particular date, that on such date (i) the fair market value
of the assets of such person is greater than the total amount of liabilities (including contingent liabilities) of such person, (ii) the present fair salable value of the assets of such person is greater than the amount that will be required to
pay the probable liabilities of such person on its debts as they become absolute and matured, (iii) such person is able to realize upon its assets and pay its debts and other liabilities, including contingent obligations, as they mature and
(iv) such person does not have unreasonably small capital. 

  
 14 

 (qq)    The Merger Agreement has been duly authorized, executed and
delivered by the Parent and Lonestar, and is a valid and binding agreement of the Parent and Lonestar, enforceable in accordance with its terms. The Parent has not received any notice of termination of the Merger Agreement from Lonestar. To the
knowledge of the Company and the Company Guarantors, the representations and warranties of Lonestar in the Merger Agreement are true and correct in all material respects, and the Parent has no reason to believe that the Parent’s, and has not
received notice from Lonestar that Lonestar’s, conditions to the closing of the acquisition transactions contemplated by the Merger Agreement will not be satisfied within the timeframe contemplated therein. 

(rr)     If executed and delivered in accordance with the terms of this Agreement on the Closing Date, the provisions of
the Escrow Agreement will be effective to create a valid and enforceable first-priority security interest in favor of the Trustee for the benefit of the Trustee and the holders of the Notes in the right, title and interest of the Escrow Issuer in
the Escrow Account. 
 Any certificate signed by any officer of the Escrow Issuer, the Company or the Guarantors and delivered to the
Representative or counsel for the Initial Purchasers in connection with the offering of the Securities shall be deemed a representation and warranty by the Escrow Issuer, the Company or the Guarantors (as applicable), as to matters covered thereby,
to each Initial Purchaser. 
 2.    Purchase and Sale. On the basis of the representations, warranties, agreements and
covenants herein contained and subject to the terms and conditions herein set forth, the Escrow Issuer agrees to issue and sell to the Initial Purchasers, and the Initial Purchasers, acting severally and not jointly, agree to purchase the Notes in
the respective amounts set forth on Schedule 1 hereto from the Escrow Issuer at 99.018% of their principal amount. The Notes will be delivered on the Closing Date to the Initial Purchasers, or the Trustee as custodian for the Depository Trust
Company (“DTC”), as applicable, against the irrevocable release of a wire transfer of immediately available funds into the Escrow Account by the Initial Purchasers of $396,072,000, being the sum of (i) $389,282,000 which amount represents
the cash proceeds from the Notes offering net of the Purchasers’ Commission payable to the Initial Purchasers in connection with the Notes plus (ii) $6,790,000 (the “Purchasers’ Commission”), which amount represents 100% of the
aggregate fees payable to the Initial Purchasers in connection with the sale of the Notes, which Purchasers’ Commission shall be earned on the Closing Date following the issuance and sale of the Notes pursuant to the terms hereof and payable on
the Effective Date. 
 3.    Delivery and Payment. 

(a)    On the Closing Date, the Escrow Issuer (or one of its affiliates) will deposit in the Escrow Account an amount of
cash equal to the accrued and unpaid interest on the Notes from and including the Closing Date through but excluding the date that is three Business Days after the Outside Date and will cause DTC to credit the Notes to the account of the Initial
Purchasers at DTC. 

  
 15 

 (b)    Delivery of and payment for the Securities shall be made at 10:00
A.M., New York City time, on August 10, 2021, or at such time on such later date not more than three Business Days (as defined below) after the foregoing date as the Representative shall designate, which date and time may be postponed by
agreement between the Representative and the Escrow Issuer or as provided in Section 9 hereof (such date and time of delivery and payment for the Securities being herein called the “Closing Date”). As used herein, “Business
Day” shall mean any day other than a Saturday, a Sunday or a legal holiday or a day on which banking institutions or trust companies are authorized or obligated by law to close in The City of New York. Delivery of the Securities shall be made
to the Representative for the respective accounts of the several Initial Purchasers against payment by the several Initial Purchasers through the Representative of the purchase price thereof to or upon the order of the Company by wire transfer
payable in same-day funds to the account specified by the Company. Delivery of the Securities shall be made through the facilities of DTC unless the Representative shall otherwise instruct. Upon satisfaction
of the Escrow Conditions on the Effective Date, as compensation for the services rendered by the Initial Purchasers to the Escrow Issuer in respect of the issuance and sale of the Notes, the Company agrees to pay the Initial Purchasers the
Purchasers’ Commission, with such Purchasers’ Commission to be paid directly to the Representatives on behalf of the Initial Purchasers by the Escrow Agent on the Effective Date. In the event a Special Mandatory Redemption occurs, the
Initial Purchasers will not be entitled to receive the Purchasers’ Commission; however, the Escrow Issuer and the Company shall nonetheless pay or reimburse all costs and expenses of the Initial Purchasers or otherwise that the Escrow Issuer,
the Company and the Guarantors have agreed to pay including but not limited to costs and expenses pursuant to Section 7 hereof and the reasonable fees and expenses of the Initial Purchasers’ outside legal counsel; provided such
reimbursable expenses shall not exceed $250,000. 
 4.    Offering by Initial Purchasers. (a) Each Initial
Purchaser acknowledges that the Securities have not been and will not be registered under the Securities Act and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons, except pursuant to an
exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. 
 (b)    Each
Initial Purchaser, severally and not jointly, represents and warrants to and agrees with the Penn Virginia Parties that: 

(i)    it has not offered or sold, and will not offer or sell, any Securities within the United States or

 16

Section 4(b)(i)(A), it has taken or will take reasonable steps to ensure that the purchaser of such Securities is aware that such sale is being made in reliance on Rule 144A; 

(iii)    neither it, nor any of its Affiliates nor any person acting on its or their behalf has engaged or
will engage in any directed selling efforts (within the meaning of Regulation S) with respect to the Securities; 

(iv)    it is an “accredited investor” (as defined in Rule 501(a) of Regulation D); 

(v)    it has complied and will comply with the offering restrictions requirement of Regulation S;

 (vi)    at or prior to the confirmation of sale of Securities (other than a sale of Securities

(within the meaning of Regulation S) a confirmation or notice to substantially the following effect: 
 “The Securities covered hereby
have not been registered under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the “Securities Act”) and may not be offered or sold within the United States or to, or for the account or benefit
of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the commencement of the offering and the date of closing of the offering, except in either case in accordance with Regulation
S or Rule 144A under the Securities Act. Additional restrictions on the offer and sale of the Securities are described in the offering memorandum for the Securities. Terms used in this paragraph have the meanings given to them by Regulation
S.”; 
 (vii)    it acknowledges that additional restrictions on the offer and sale of the
Securities are described in the Disclosure Package and the Final Memorandum; and 
 (viii)    it
acknowledges and agrees that the Company and, for purposes of the “no registration” opinions to be delivered to the Initial Purchasers pursuant to Sections 6(a) and 6(b), counsel for the Company and counsel for the Initial Purchasers,
respectively, may rely upon the accuracy of the representations and warranties of the Initial Purchasers, and compliance by the Initial Purchasers with their agreements, contained in paragraphs (a) and (b) above, and each Initial Purchaser
hereby consents to such reliance. 

  
 17 

 5.    Agreements. Each Penn Virginia Party, jointly and
severally, and, upon execution and delivery of the Joinder Agreement by any Lonestar Guarantor, each such Lonestar Guarantor, agrees with each Initial Purchaser that: 

(a)    The Escrow Issuer and the Company will furnish to each Initial Purchaser and to counsel for the Initial Purchasers,
without charge, during the period referred to in Section 5(c) below, as many copies of the materials contained in the Disclosure Package and the Final Memorandum and any amendments and supplements thereto as they may reasonably request. 

(b)    The Escrow Issuer and the Company will prepare a final term sheet, containing solely a description of final terms
of the Securities and the offering thereof, in the form approved by you and attached as Schedule II hereto. 

(c)    The Escrow Issuer and the Company will not amend or supplement the Disclosure Package or the Final Memorandum,
other than by filing documents under the Exchange Act that are incorporated by reference therein, without the prior written consent of the Representative, which consent shall not be unreasonably withheld; provided, however, that prior
to the completion of the distribution of the Securities by the Initial Purchasers (as defined by the Initial Purchasers), the Escrow Agent and the Company will not file any document under the Exchange Act that is incorporated by reference in the
Disclosure Package or the Final Memorandum unless, prior to such proposed filing, the Escrow Agent and the Company have furnished the Representative with a copy of such document for their review and the Representatives have not reasonably objected
to the filing of such document. The Escrow Agent and the Company will promptly advise the Representatives when any document filed under the Exchange Act that is incorporated by reference in the Disclosure Package or the Final Memorandum shall have
been filed with the Commission (as defined below).  
 (d)    If at any time prior to the completion of the sale
of the Securities by the Initial Purchasers (as determined by the Representative), 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 in order to make the statements therein, in the light of the circumstances under which they were made or the circumstances then prevailing, not misleading, or if it should be necessary to
amend or supplement the Disclosure Package or the Final Memorandum to comply with applicable law, the Escrow Issuer and the Company will promptly (i) notify the Representative of any such event; (ii) subject to the requirements of
Section 5(c), prepare an amendment or supplement that will correct such statement or omission or effect such compliance; and (iii) supply any supplemented or amended Disclosure Package or Final Memorandum to the several Initial Purchasers
and counsel for the Initial Purchasers without charge in such quantities as they may reasonably request. 

(e)    Without the prior written consent of the Representative, none of the Penn Virginia Parties has given and will not
give to any prospective purchaser of the Securities any written information concerning the offering of the Securities other than materials contained in the Disclosure Package, the Final Memorandum or any other offering materials prepared by or with
the prior written consent of the Representative. 

  
 18 

 (f)    The Escrow Issuer and the Company will arrange, if necessary, for
the qualification of the Securities for sale by the Initial Purchasers under the laws of such jurisdictions as the Representative may designate (including Japan and 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 Escrow Issuer and the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to 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 Escrow Issuer and the Company will promptly advise the Representative of the receipt
by any Penn Virginia Party 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)    During the period of one year after the Closing Date, the Penn Virginia Parties will not, and will not permit any
of their Affiliates to, resell any Securities that have been acquired by any of them, except for Securities purchased by the Penn Virginia Parties or any of their Affiliates and resold in a transaction registered under the Securities Act. 

(h)    None of the Penn Virginia Parties, their Affiliates or any person acting on their behalf will, directly or
indirectly, make offers or sales of any security, or solicit offers to buy any security, under circumstances that would require the registration of the Securities under the Securities Act. 

(i)    None of the Penn Virginia Parties, their Affiliates or any person acting on their behalf will engage in any
directed selling efforts (within the meaning of Regulation S) with respect to the Securities; 
 (j)    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 Escrow Issuer and 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 or it is not exempt from such reporting requirements pursuant to and in compliance with Rule 12g3-2(b) under 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 restricted securities. 

(k)    The Penn Virginia Parties will cooperate with the Representative and use their best efforts to permit the
Securities to be eligible for clearance and settlement through DTC.

extent applicable, a legend in substantially the form as contained in “Transfer Restrictions” in the Preliminary Memorandum and the Final Memorandum for the time period and upon the other terms stated therein. 

(m)    The Penn Virginia Parties will not for a period of 90 days following the Execution Time, without the prior written
consent of BofA Securities, Inc. (“BofA”) offer, sell, contract to sell, pledge, otherwise dispose of, or enter into any transaction which is designed to, 

  
 19 

 
or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by any Penn Virginia Party or
any Affiliate of any Penn Virginia Party or any person in privity with any Penn Virginia Party or any Affiliate of any Penn Virginia Party, directly or indirectly, or announce the offering, of any debt securities issued or guaranteed by any Penn
Virginia Party (other than the Securities). 
 (n)    No Penn Virginia Party will 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. 
 (o)    The Escrow Issuer and the Company will, for a period of twelve months following the
Execution Time, furnish to the Representative (i) all reports or other communications (financial or other) generally made available to its shareholders, and deliver such reports and communications to the Representative as soon as they are
available, unless such documents are furnished to or filed with the Securities and Exchange Commission (the “Commission”) or any securities exchange on which any class of securities of the Company is listed and generally made available to
the public and (ii) such additional information concerning the business and financial condition of the Company as the Representative may from time to time reasonably request (such statements to be on a consolidated basis to the extent the
accounts of the Penn Virginia Parties are consolidated in reports furnished to its shareholders). 
 (p)    The Escrow
Issuer, the Company and their respective subsidiaries will comply with all applicable securities and other laws, rules and regulations, including, without limitation, the Sarbanes-Oxley Act, and use its best efforts to cause the Company’s
directors and officers, in their capacities as such, to comply with such laws, rules and regulations, including, without limitation, the provisions of the Sarbanes-Oxley Act.

included or incorporated by reference 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, earnings,
business or properties of the Escrow Issuer, the Company, the Guarantors and their respective 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). 
 (d)    At the
Execution Time and at the Closing Date, the Escrow Issuer and the Company shall have requested and caused each of Grant Thornton LLP and BDO to furnish to the Representative letters, dated respectively as of the Execution Time and as of the Closing
Date, in form and substance satisfactory to the Representative, containing statements and information of the type customarily included in accountants’ “comfort letters” to initial purchasers with respect to the financial statements
and certain financial information contained in each of the Disclosure Package and the Final Memorandum; provided that each of the letter delivered on the Closing Date shall use a “cut-off”
date no more than three Business Days prior to such Closing Date. 
 (e)    Subsequent to the Execution Time or, if
earlier, the dates as of which information is given in the Disclosure Package (exclusive of any amendment or supplement thereto) and the Final Memorandum (exclusive of any amendment or supplement thereto), there shall not have been (i) any
change specified in the letter or letters referred to in paragraph (d) of this Section 6; or (ii) any material adverse change, or any development involving a prospective material change, in or affecting the condition (financial or
otherwise), prospects, earnings, business or properties of the Escrow Issuer, the Company, the Guarantors and their respective 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), the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the
Representative, 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). 

  
 22 

 (f)    At the Execution Time and at the Closing Date, the Escrow Issuer
and the Company shall have requested and caused each of D&M and WVG, independent petroleum engineers, to furnish to the Representative letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance
satisfactory to the Representative, covering the oil and gas reserves information included or incorporated by reference in the Disclosure Package and the Final Memorandum and other customary matters; provided that each of the letter delivered
on the Closing Date shall use a “cut-off” date no more than three Business Days prior to such Closing Date. 

(g)    On the Closing Date, the Escrow Issuer and the Company shall have furnished to the Representative a certificate,
dated the Closing Date and addressed to the Initial Purchasers, of the Parent’s chief financial officer with respect to certain financial data contained in the Disclosure Package and the Final Memorandum, providing “management
comfort” with respect to such information, in form and substance reasonably satisfactory to the Representative. 

(h)    The Securities shall be eligible for clearance and settlement through DTC. 

(i)    The Representative shall have received on and as of the Closing Date, reasonably satisfactory evidence of the good
standings of the Penn Virginia Parties in their respective jurisdictions of organization or formation, as applicable, and their good standings (where such designation is applicable) as foreign entities in such other jurisdictions as the
Representative may reasonably request. 
 (j)    Prior to the Closing Date, the Penn Virginia Parties shall have
furnished to the Representative such further information, certificates and documents as the Representative may reasonably request. 

(k)    The Escrow Issuer, the Trustee and the Escrow Agent shall have executed the Escrow Agreement and the Representative
shall have received executed copies thereof. The Escrow Agent shall have established the Escrow Account and shall have provided to the Representative evidence thereof reasonably satisfactory to the Representative. All other actions to be taken under
the Escrow Agreement by the Escrow Issuer as of the Closing Date in order to effect the escrow arrangements contemplated by the Disclosure Package (including, without limitation, the deposit of cash into the Escrow Account in accordance with the
Escrow Agreement) shall have been taken. 
 If any of the conditions specified in this Section 6 shall not have been fulfilled when and
as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representative and counsel for the Initial Purchasers, this
Agreement and all obligations of the Initial Purchasers hereunder may be cancelled at, or at any time prior to, the Closing Date by the Representative. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile
confirmed in writing. 
 The documents required to be delivered by this Section 6 will be delivered to counsel for the Initial
Purchasers on the Closing Date. All opinions, letters, certificates and evidence mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably
satisfactory to counsel for the Initial Purchasers. 

  
 23 

 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 Purchasers set forth in Section 6 hereof is not satisfied or because of any refusal, inability or failure on the part of any Penn Virginia Party to
perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Initial Purchasers, the Penn Virginia Parties will, jointly and severally, reimburse the Initial Purchasers severally through BofA 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) Each Penn Virginia Party, jointly and severally, agrees to
indemnify and hold harmless each Initial Purchaser, the directors, officers, employees, Affiliates and agents of each Initial Purchaser and each person who controls any 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 or any other written information used by or on behalf of the Penn Virginia Parties 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 necessary in order 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 Penn Virginia Parties 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 or the Final Memorandum, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with information furnished to the Escrow Issuer and the Company in writing by any
Initial Purchaser through the Representative expressly for use in the Preliminary Memorandum or the Final Memorandum or amendment or supplement thereto, as the case may be, and such written information shall consist solely of (i) the statements
set forth in the last paragraph of the cover page and (ii), under the heading “Plan of Distribution”, the ninth and tenth paragraphs in the Preliminary Memorandum and the
Final Memorandum (the “Offering Memorandum Disclosures”) furnished to the Penn Virginia Parties by or on behalf of any Initial Purchaser through the Representative specifically for inclusion therein. This indemnity agreement will be in
addition to any liability that the Penn Virginia Parties may otherwise have. 
 (b)    Each Initial Purchaser severally,
and not jointly, agrees to indemnify and hold harmless each Penn Virginia Party, each of their respective directors, each of their respective officers, and each person who controls any Penn Virginia Party within the meaning of either the

  
 24 

 
Securities Act or the Exchange Act, to the same extent as the foregoing indemnity to each Initial Purchaser, but only with reference to written information relating to such Initial Purchaser
furnished to the Penn Virginia Parties by or on behalf of such Initial Purchaser through the Representative 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 any Initial Purchaser may otherwise have. The Escrow Issuer, the Company and each of the Guarantors acknowledges that the Offering Memorandum Disclosures constitute the only information furnished
in writing by or on behalf of the Initial Purchasers 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 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 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 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 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. 

  
 25 

 (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 Penn Virginia Parties and the Initial Purchasers severally 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 Penn Virginia Parties and one or more of
the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Penn Virginia Parties on the one hand and by the Initial Purchasers on the other from the offering of the Securities. If the
allocation provided by the immediately preceding sentence is unavailable for any reason, the Penn Virginia Parties and the Initial Purchasers severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits
but also the relative fault of the Penn Virginia Parties on the one hand and the Initial Purchasers 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 Penn Virginia Parties shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Initial Purchasers shall be deemed to be equal to the
total purchase discounts and commissions. 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 Purchasers 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 Purchasers 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 any Initial Purchaser be required to contribute any amount in excess of the amount by which the total purchase discounts and commissions received by such Initial Purchaser with
respect to the offering of the Securities exceeds the amount of any damages that such 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 any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to
contribute pursuant to this Section 8 are several, and not joint, in proportion to their respective commitments as set forth opposite their names in Schedule I. For purposes of this Section 8, each person who controls an Initial Purchaser
within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee, Affiliate and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls
the Penn Virginia Parties within the meaning of either the Securities Act or the Exchange Act and each officer and director of the Penn Virginia Parties shall have the same rights to contribution as the Penn Virginia Parties, subject in each case to
the applicable terms and conditions of this paragraph (d). 
 9.    Default by an Initial Purchaser. If any
one or more Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations
under this Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set 

  
 26 

 
forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities
which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser or Initial
Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any
obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser or the Penn Virginia Parties,
except as provided in Section 11. In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representative shall
determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Penn
Virginia Parties or any nondefaulting Initial Purchaser for damages occasioned by its default hereunder. 

10.    Termination. This Agreement shall be subject to termination in the absolute discretion of the
Representative, 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 in securities generally on the Nasdaq Global Select Market shall have been suspended or limited or
minimum prices shall have been established on such exchange; (ii) a banking moratorium shall have been declared either by U.S. federal or New York State authorities; (iii) there shall have occurred a material disruption in commercial
banking or securities settlement or clearance services; or (iv) 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 the effect
of which on financial markets is such as to make it, in the sole judgment of the Representative, 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). 
 11.    Representations and Indemnities to Survive. The
respective agreements, representations, warranties, indemnities and other statements of the Penn Virginia Parties or their respective officers and of the Initial Purchasers 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 Purchasers or the Penn Virginia Parties 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. 

12.    Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the
Representative, will be mailed or delivered to BofA Securities, Inc., 1540 Broadway, 26th Floor, New York, NY 10036, Attention: High Yield Legal Department, Facsimile: 212-901-7897; or, if sent to the Company, will be mailed or delivered to 16285 Park Ten Place, Suite 500, Houston Texas 77084, attention of Katherine Ryan, Vice President,
Chief Legal Counsel and Corporate Secretary. 
 13.    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. 

  
 27 

 14.    Recognition of the U.S. Special Resolution Regimes.
(a) In the event that any Initial Purchaser that is a Covered Entity (as defined below) becomes subject to a proceeding under a U.S. Special Resolution Regime (as defined below), the transfer from such Initial Purchaser of this Agreement, and
any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the
laws of the United States or a state of the United States. 
 (b)    In the event that any Initial Purchaser that is a
Covered Entity or a BHC Act Affiliate (as defined below) of such Initial Purchaser becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Initial Purchaser are
permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States. 

As used in this Section 14, “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be
interpreted in accordance with, 12 U.S.C. § 1841(k); “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b),
(ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b) or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R.
§ 382.2(b); “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable; and “U.S. Special Resolution Regime” means
each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder. 

15.    Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral)
between the Penn Virginia Parties and the Initial Purchasers, or any of them, with respect to the subject matter hereof. 

16.    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. 

17.    Waiver of Jury Trial. Each Penn Virginia Party hereby irrevocably waives, to the fullest extent permitted by
applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. 

18.    No Fiduciary Duty. Each Penn Virginia Party hereby acknowledges that (a) the purchase and sale of the
Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Penn Virginia Parties, on the one hand, and the Initial Purchasers and any Affiliate through which it may be
acting, on the other, (b) the Initial Purchasers are acting as 

  
 28 

 
principal and not as an agent or fiduciary of the Penn Virginia Parties and (c) the Penn Virginia Parties’ engagement of the Initial Purchasers in connection with the offering and the
process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, each Penn Virginia Party agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of
whether any of the Initial Purchasers has advised or is currently advising such Penn Virginia Party on related or other matters). Each Penn Virginia Party agrees that they will not claim that the Initial Purchasers have rendered advisory services of
any nature or respect, or owe an agency, fiduciary or similar duty to the Penn Virginia Parties, in connection with such transaction or the process leading thereto. 

19.    Waiver of Tax Confidentiality. Notwithstanding anything herein to the contrary, purchasers of the Securities
(and each employee, representative or other agent of a purchaser) may disclose to any and all persons, without limitation of any kind, the U.S. tax treatment and U.S. tax structure of any transaction contemplated herein and all materials of any kind
(including opinions or other tax analyses) that are provided to the purchasers of the Securities relating to such U.S. tax treatment and U.S. tax structure, other than any information for which nondisclosure is reasonably necessary in order to
comply with applicable securities laws. 
 20.    Counterparts. This Agreement may be signed in one or more
counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile or other electronic
transmission (i.e., a “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart thereof. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition
herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation
of this Agreement. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Agreement or any document to be signed in connection with this Agreement shall be
deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a
paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means. 

21.    Headings. The section headings used herein are for convenience only and shall not affect the construction
hereof. 
 22.    Compliance with USA PATRIOT Act. In accordance with the requirements of the USA PATRIOT Act
(Title III of Pub. L. 107-56 (signed into law on October 26, 2001)), the Initial Purchasers are required to obtain, verify and record information that identifies its clients, including the Escrow Issuer,
the Company and the Guarantors, which information may include the name and address of its clients, as well as other information that will allow the Initial Purchasers to properly identify its clients. 

If the foregoing is in accordance with your understanding of our agreement, please sign and return to us the enclosed duplicate hereof,
whereupon this letter and your acceptance shall represent a binding agreement among the Penn Virginia Parties and the several Initial Purchasers.

Sheet 
 Term Sheet dated July 27, 2021 to the Preliminary Offering Memorandum dated July 26, 2021. This Term Sheet is
qualified in its entirety by reference to the Preliminary Offering Memorandum. The information in this Term Sheet supplements the Preliminary Offering Memorandum and supersedes the information in the Preliminary Offering Memorandum to the extent it
is inconsistent with the information in the Preliminary Offering Memorandum. Capitalized terms used in this Term Sheet but not defined have the meanings given to them in the Preliminary Offering Memorandum. 

 

			
	Issuer	  	Penn Virginia Escrow LLC, to be merged with and into Penn Virginia Holdings, LLC on the Escrow Release Date
		
	Guarantors	  	Prior to the Escrow Release Date, the notes will not be guaranteed. From and after the Escrow Release Date and upon the consummation of the Escrow Merger, all of the Issuer’s restricted subsidiaries that guarantee indebtedness

	Trade Date	  	July 27, 2021
		
	Settlement Date	  	August 10, 2021 (T+10). We expect that delivery of the notes will be made against payment therefor on or about August 10, 2021, which is ten business days following the date of pricing of the notes. This settlement cycle
is referred to as “T+10.” Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days, unless the
parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of the offering memorandum or the next seven succeeding business days will be required, by virtue of the fact that the notes initially
will settle T+10, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement.

The following changes shall be made to clause (22) under the definition of “Permitted Liens”: 

“(22)     any Lien renewing, extending, refinancing or refunding a Lien permitted by clauses
(1)(2) through (21) above; provided that (a) the principal amount of the Indebtedness secured by such Lien is not increased except by an amount equal to a reasonable premium or other reasonable amount
paid, and fees and expenses reasonably incurred, in connection therewith and by an amount equal to any existing commitments unutilized thereunder and (b) no assets encumbered by any such Lien other than the assets permitted to be encumbered

SECURED CONVERTIBLE PROMISSORY NOTE

  

	US $XXX,XXX.XX

	 
	 	Fort Lauderdale, Florida

 

FOR
VALUE RECEIVED, Veritas Farms, Inc. with a current principal office address of 1512 E Broward Blvd, Suite 300, Fort Lauderdale, Florida
33301 (the “Maker”), agrees and promises to pay to the order of the ________________, its successors and/or assigns (the “Holder”)
at the Holder’s address, or such other place as designated in writing by the Holder of this Secured Convertible Promissory Note
(“Promissory Note”), the principal sum of XXX Dollars (US $XXX,XXX.XX) (“Principal”), with interest (“Interest”)
at a rate of 8% per annum. All unpaid Principal, together with any then unpaid and accrued Interest and other amounts payable hereunder,
shall be due and payable if not converted pursuant to the terms and conditions of this Promissory Note on the earlier of (i) _________,
or (ii) following an Event of Default (as defined below) (such date, the “Maturity Date”). All
payments due hereunder shall be paid in lawful money of the United States of America which shall be legal tender in payment of all debts,
in immediately available funds, without offset, deduction or recoupment. Any payment by check or draft shall be subject to the condition
that any receipt issued therefore shall be ineffective unless the amount due is actually received by the Holder. Each payment shall be
applied first to the payment of all costs, fees and expenses incurred by or payable to the Holder in connection with the collection or
enforcement of this Promissory Note; second, to the payment of all accrued and unpaid Interest hereunder; and third, to the payment of
the unpaid Principal amount.

 

The proceeds of this Promissory
Note shall be used by the Maker only for the purpose of funding Maker’s accounts payable liabilities and for working capital.

 

As collateral security for payment
of the obligations under this Promissory Note, the Maker and the Holder have agreed that all obligations hereunder will be secured by
all the assets of the Maker, and Maker hereby grants to Holder a security interest and lien in all of Maker's assets, wherever located,
whether tangible or intangible, now existing, or hereafter acquired.

 

Optional Conversion. Prior to
the Maker closing a financing through the sale and issuance of the Company’s equity securities, debt, convertible debt, a combination
of the foregoing or otherwise (“Conversion Securities”), on or prior to the Due Date, (the “Financing”), the Holder
shall have the right, in its sole discretion, to convert (A) all or a partial amount of the Principal, and (B) all or a partial amount
of the accrued but unpaid Interest thereon through and as of the date of the closing of the Financing, into the identical Conversion Securities
issued at such Financing .

 

Mechanics of Conversion. On the
date fixed for the closing of the Financing and conversion hereunder in accordance with the foregoing provisions (the “Conversion
Date”), in the event the Holder determines to convert all or a partial amount of the Principal and or accrued but unpaid Interest
into the Financing, the Holder shall surrender this Promissory Note for cancellation at the principal office address of the Maker and
if less than all of the Principal and accrued but unpaid Interest is converted, the Company shall issue a new promissory note to the Holder
evidencing the balance of the Promissory Note.. Following the surrender of this Promissory Note for conversion, the Maker shall deliver
or cause to be delivered to the Holder the Conversion Securities on the Conversion Date issuable upon the conversion of this Promissory
Note in accordance with the provisions hereof, and in the event the Holder converts all of the Principal and accrued but unpaid Interest
into the Financing, this Promissory Note shall be deemed fully paid.

 

This Promissory Note may be prepaid
at any time prior to the Due Date.

 

    1 

     

    

 

The occurrence of any of the following
shall constitute an “Event of Default” under this Promissory Note (each, an “Event of Default”): (a) Maker shall
fail to pay any Principal or Interest when due and payable hereunder; or (b) Maker shall fail to deliver the Conversion Securities in
accordance with the terms hereof; or (c) a receiver, trustee or other similar official shall be appointed over Maker; or (d) Maker shall
make a general assignment for the benefit of creditors; or (e) Maker shall file a petition for relief under any bankruptcy, insolvency
or similar law; or (f) an involuntary proceeding shall be commenced or filed against Maker; or (g) Maker shall default or otherwise fail
to observe or perform any covenant, obligation, condition or agreement of Maker contained herein; or (h) any representation, warranty
or other statement made or furnished by or on behalf of Maker to Holder herein shall be false, incorrect, incomplete or misleading; or
(i) any lawsuit, money judgment, writ or similar process shall be entered or filed against Maker or any subsidiary of Maker or any of
its property or other assets for more than $100,000.00, unless otherwise consented to by Holder.

 

While an Event of Default exists,
the Maker hereby promises to pay Interest on the unpaid balance of this Promissory Note then outstanding at the rate representing eighteen
percent (18%) per annum or the highest rate allowed by law, whichever is lower, from the date of the Event of Default to until and including
the date actually paid. It is the intent of parties hereto that in no event shall the amount of Interest due or payment in the nature
of interest payable hereunder exceed the maximum rate of interest allowed by applicable law, as amended from time to time, and in the
event any such payment is paid by the Maker or received by Holder, then such excess sum shall be credited as a prepayment of principal,
unless the Maker shall notify the Holder, in writing, that the Maker elects to have such excess sum returned forthwith.

 

This Promissory Note shall
not be modified except by an instrument in writing signed by the party against whom enforcements of such modification is sought. This
Promissory Note shall be governed and construed in accordance with the laws of the State of Florida, without regard to conflict of laws
or principles thereof. Any suit or proceeding relating to this Promissory Note shall be brought or instituted only in a court of competent
jurisdiction in Broward County, Florida. No waiver by the Holder of any default hereunder shall be deemed to constitute a waiver of any
subsequent default. No exercise of any right or remedy hereunder shall preclude the exercise of any other right or remedy. The Maker agrees
to pay or reimburse the Holder for all costs and expenses of enforcing and preserving its rights under this Promissory Note or any document
or instrument executed in connection herewith (including reasonable attorneys’ fees and costs, whether in or out of court, in original
or appellate proceedings or in bankruptcy).

The Maker and all others who may
become liable for the payment hereof jointly and severally: (a) waive presentment for payment, demand, notice of demand, notice of non-payment
or dishonor, protest and notice of protest of this Promissory Note, and all other notices in connection with the delivery, acceptance,
performance, default, or enforcement of the payment of this Promissory Note, (b) consent to all extensions of time, renewals, postponements
of time of payment of this Promissory Note, waivers or other modifications hereof from time to time prior to or after the Maturity Date
hereof, whether by acceleration or in due course, without notice, consent or consideration to any of the foregoing, (c) agree to any substitution,
exchange, addition or release of any party or person primarily or secondarily liable hereon, and (d) agree that, notwithstanding the occurrence
of any of the foregoing (except by the express written release by Holder), the Maker shall be and remain directly and primarily liable
for all sums due under this Promissory Note.

 

All issue taxes, documentary stamp
taxes, or other taxes (if any) required by law at any time to be affixed to this Promissory Note shall be paid by the Maker. The Maker
agrees to indemnify and hold the Holder, its affiliates, successors and assigns harmless from and against the aggregate of all expenses,
losses, costs, deficiencies, liabilities, penalties, fines, fees and damages (including related reasonable counsel and paralegal fees
and expenses) incurred or suffered by the Holder arising out of or resulting from the Maker’s failure to pay such documentary stamp
or other tax.

 

    2 

     

    

 

IN
WITNESS WHEREOF, the Maker has duly executed this Promissory Note as of the day and year first above written.
