LLC, a Delaware limited liability company (the “Company”) and, solely for purposes of Section 5, Prometheus PubCo Inc., a Delaware corporation (to be renamed Presidio Production Company prior to the Effective Date) (“Parent”).

WHEREAS, upon the closing of the transactions contemplated by the BCA (the “Closing”), the Company will become a wholly owned subsidiary of Parent; and

WHEREAS, as of the Closing (the “Effective Date”), the Company desires to continue to employ Executive and Executive desires to continue to be employed by the Company on the terms and conditions set forth in this Agreement.

NOW, THEREFORE, for good and valuable consideration, including but not limited to Executive’s continued access to, use and training relating to the Company’s Confidential and Proprietary Information and trade secrets, including key information about and goodwill in, the Company’s customers, clients and employees, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Employment Term. The Company hereby agrees to continue to employ Executive, and Executive hereby agrees to continue to be employed by the Company, upon the terms and conditions contained in this Agreement. The period during which Executive is employed with the Company pursuant to this Agreement shall commence on the Effective Date and continue until terminated pursuant to Section 8 of this Agreement (such period of employment, the “Term”). Notwithstanding anything herein to the contrary, in the event the BCA is terminated or the Closing does not occur, this Agreement shall be void ab initio and of no force and effect.

2. Employment Duties.

Executive shall report directly to the Co-Chief Executive Officers of the Company. Executive shall devote Executive’s full working time, attention and best efforts to perform Executive’s duties hereunder in a capacity and in a manner consistent with Executive’s position for the Company. For the avoidance of doubt, this Section 2 shall not be interpreted as prohibiting Executive from (i) managing Executive’s personal investments, (ii) engaging in charitable or civic activities and (iii) participating on boards of directors or similar bodies of non- profit organizations, in each case of (i) – (iii), so long as such activities do not, individually or in the aggregate, (a) materially interfere with the performance of Executive’s duties and responsibilities hereunder, (b) create a fiduciary conflict, or (c) result in a violation of Section 13 of this Agreement or any other restrictive covenant agreement between the Company or any of its Affiliates and Executive. To the extent requested by Parent, Executive shall also serve as an executive officer and/or board member of the board of directors (or similar governing body) of any entity that directly, or indirectly through one or more intermediaries, controls, is controlled by, or is under common control with, the Company (each, an “Affiliate”) without any additional compensation paid therefor. Executive shall work remotely, provided, that, from time to time Executive may be required to report to the Company’s offices in Fort Worth, Texas, as reasonably required to perform Executive’s duties (the “Work Location Arrangement”).

4. Annual Performance Bonus. Beginning in calendar year 2026, for each calendar year during the Term, Executive shall be eligible to earn an annual cash bonus (the “Annual Bonus”) with a target Annual Bonus of 80% of Base Salary (the “Target Bonus”), subject to upward adjustment, as determined by the Board; provided, that, for calendar year 2026, Executive’s Annual Bonus shall be not less than the Target Bonus (without proration). The Annual Bonus shall be based upon the achievement of performance goals to be determined in the Board’s discretion, after consultation with the Chief Executive Officer(s) of the Company (the “CEO(s)”) at the beginning of each calendar year. The Annual Bonus, if any, shall be paid to Executive in the calendar year immediately following the year to which it relates, but no later than March 15th of such year, subject to Executive’s continued employment on the final day of the calendar year to which such Annual Bonus relates, except as otherwise provided in Section 9. Executive’s annual bonus in respect of calendar year 2025 (if any) shall be paid in accordance with the BCA.

5. Equity Incentive Awards. Executive will participate in and be granted awards under the Parent 2025 Equity Incentive Plan (the “Equity Plan”), to be effective as of the effective date of Parent’s Form S-8 (the “S-8 Effective Date”). As of the Closing (but effective as of the S-8 Effective Date), Executive shall receive an incentive equity award of 264,000 restricted stock units, pursuant to the Restricted Stock Unit Award Agreement attached hereto as Exhibit A. Beginning in calendar year 2027 and in each calendar year thereafter during the Term, no later than June 30th of such year, Executive shall be granted one or more equity incentive awards (the “Annual Equity Award”) under the Equity Plan (provided Executive remains employed with the Company on the applicable grant date) with a target grant date fair market value equal to three (3) times Executive’s Base Salary (the “Target Award Value”), with such actual grant date fair market value subject to the discretion of the Board (or compensation committee thereof); provided that, the Annual Equity Award granted in calendar year 2027 shall have a grant date fair market value at least equal to the Target Award Value. Annual Equity Awards shall have such terms and conditions as determined by the Board (or compensation committee thereof), including any performance-vesting conditions; provided, that, such terms shall be substantially similar to the terms and conditions provided to similarly situated executives of the Company.

Nothing in this Section 14 shall limit Executive’s right to make Permitted Disclosures as provided in Section 13(b) above.

15. Injunctive Relief and Specific Performance. Executive understands and agrees that Executive’s covenants under Sections 11, 13 and 14 are special and unique and that the Company and its Affiliates may suffer irreparable harm if Executive breaches any of Sections 11, 13, or 14 because monetary damages would be inadequate to compensate the Company and its Affiliates for the breach of any of these sections. Accordingly, Executive acknowledges and agrees that the Company shall, in addition to any other remedies available to the Company at law or in equity, be entitled to specific performance and injunctive or other equitable relief by a federal or state court in Delaware to enforce the provisions of Sections 11, 13 and/or 14 without the necessity of posting a bond or proving actual damages, without liability should such relief be denied, modified or vacated, and to obtain attorney’s fees in respect of the foregoing if the Company prevails in any such action or proceeding. Additionally, in the event of a breach or threatened breach by Executive of Section 13, in addition to all other available legal and equitable rights and remedies, the Company shall have the right to cease making, and to seek repayment of, payments, if any, made or being made pursuant to Section 9(b)(ii) or Section 9(b)(iii) hereunder. Executive also recognizes that the territorial, time and scope limitations set forth in Section 13 are reasonable and are properly required for the protection of the Company and its Affiliates, and in the event that a court of competent jurisdiction deems any territorial, time or scope limitation in this Agreement to be unreasonable, the Company and Executive agree, and Executive submits, to the reduction of any or all of said territorial, time or scope limitations to such an area, period or scope as said court shall deem reasonable under the circumstances.

If to Executive: At Executive’s home address as then shown in the Company’s personnel records,

or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt.

(b) This Agreement is personal to Executive and shall not be assigned by Executive. Any purported assignment by Executive shall be null and void from the initial date of the purported assignment. The Company may assign this Agreement to any successor or assign (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company or to an affiliate, and Executive hereby explicitly consents to such assignment. This Agreement shall inure to the benefit of the Company and its successors and assigns.

(c) This Agreement contains the entire agreement between the parties with respect to the subject matter hereof and supersedes all other agreements, term sheets, offer letters, and drafts thereof, oral or written, between the parties hereto with respect to the subject matter hereof, including, without limitation, the Employment Agreement, dated July 28, 2025, by and between Executive and the Company (the “Prior Agreement”); provided, however, that except for the Prior Agreement, the provisions of this Agreement are in addition to and complement (and do not replace or supersede) any other written agreement(s) or parts thereof between Executive and the Company or any of its Affiliates that create restrictions on Executive with respect to confidentiality, non-disclosure, non-competition, non-solicitation or non-disparagement. No promises, statements, understandings, representations or warranties of any kind, whether oral or in writing, express or implied, have been made to Executive by any person or entity to induce Executive to enter into this Agreement other than the express terms set forth herein, and Executive is not relying upon any promises, statements, understandings, representations, or warranties other than those expressly set forth in this Agreement.

12

(d) No change or modification of this Agreement shall be valid unless the same shall be in writing and signed by all of the parties hereto. No waiver of any provisions of this Agreement shall be valid unless in writing and signed by the party charged with the waiver. No waiver of any of the provisions of this Agreement shall be deemed, or shall constitute, a waiver of any other provision, whether or not similar, nor shall any waiver constitute a continuing waiver, unless so provided in the waiver.

(e) If any provisions of this Agreement (or portions thereof) shall, for any reason, be held invalid or unenforceable, such provisions (or portions thereof) shall be ineffective only to the extent of such invalidity or unenforceability, and the remaining provisions of this Agreement (or portions thereof) shall nevertheless be valid, enforceable and of full force and effect. If any court of competent jurisdiction finds that any restriction contained in this Agreement is invalid or unenforceable, then the parties hereto agree that such invalid or unenforceable restriction shall be deemed modified so that it shall be valid and enforceable to the greatest extent permissible under law, and if such restriction cannot be modified so as to make it enforceable or valid, such finding shall not affect the enforceability or validity of any of the other restrictions contained herein.

(f) This Agreement may be executed in two or more identical counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party. In the event that any signature is delivered by facsimile transmission or by an e-mail which contains a portable document format (.pdf) file of an executed signature page, such signature page shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof.

(g) The section or paragraph headings or titles herein are for convenience of reference only and shall not be deemed a part of this Agreement. The parties have jointly participated in the drafting of this Agreement, and the rule of construction that a contract shall be construed against the drafter shall not be applied. The terms “including,” “includes,” “include” and words of like import shall be construed broadly as if followed by the words “without limitation.” The terms “herein,” “hereunder,” “hereof” and words of like import refer to this entire Agreement instead of just the provision in which they are found.

(h) Notwithstanding anything to the contrary in this Agreement:

(i) The parties agree that this Agreement shall be interpreted to comply with or be exempt from Section 409A of the Code and the regulations and authoritative guidance promulgated thereunder to the extent applicable (collectively “Section 409A”), and all provisions of this Agreement shall be construed in a manner consistent with the requirements for avoiding taxes or penalties under Section 409A. Except when resulting from the Company’s material negligence, in no event whatsoever will the Company, any of its Affiliates, or any of their respective directors, officers, agents, attorneys, employees, executives, shareholders, investors, members, managers, trustees, fiduciaries, representatives, principals, accountants, insurers, successors or assigns be liable for any additional tax, interest or penalties that may be imposed on Executive under Section 409A or any damages for failing to comply with Section 409A.

13

(ii) A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits considered “nonqualified deferred compensation” under Section 409A upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Section 409A, and for purposes of any such provision of this Agreement, references to a “resignation,” “termination,” “terminate,” “termination of employment” or like terms shall mean separation from service. If any payment, compensation or other benefit provided to Executive in connection with the termination of Executive’s employment is determined, in whole or in part, to constitute “nonqualified deferred compensation” within the meaning of Section 409A and Executive is a specified employee as defined in Section 409A(2)(B)(i) of the Code, no part of such payments shall be paid before the day that is six months plus one day after the date of termination or, if earlier, ten business days following Executive’s death (the “New Payment Date”). The aggregate of any payments that otherwise would have been paid to Executive during the period between the date of termination and the New Payment Date shall be paid to Executive in a lump sum on such New Payment Date. Thereafter, any payments that remain outstanding as of the day immediately following the New Payment Date shall be paid without delay over the time period originally scheduled, in accordance with the terms of this Agreement.

(iii) All reimbursements for costs and expenses under this Agreement shall be paid in no event later than the end of the calendar year following the calendar year in which Executive incurs such expense. With regard to any provision herein that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by Section 409A, (i) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (ii) the amount of expenses eligible for reimbursements or in-kind, benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in- kind benefits to be provided in any other taxable year.

(iv) If under this Agreement, an amount is paid in two or more installments, for purposes of Section 409A, each installment shall be treated as a separate payment. Whenever a payment under this Agreement specifies a payment period with reference to a number of days (e.g., “payment shall be made within thirty days following the date of termination”), the actual date of payment within the specified period shall be within the sole discretion of the Company.

(v) This Agreement will be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule. AS A SPECIFICALLY BARGAINED INDUCEMENT FOR EACH OF THE PARTIES TO ENTER INTO THIS AGREEMENT (EACH PARTY HAVING HAD OPPORTUNITY TO CONSULT COUNSEL), EACH PARTY EXPRESSLY WAIVES THE RIGHT TO TRIAL BY JURY IN ANY PROCEEDING RELATING TO OR ARISING IN ANY WAY FROM THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED IN THIS AGREEMENT.

14

(vi) Executive hereby represents and warrants to the Company that (i) the execution, delivery and performance of this Agreement by Executive do not and shall not conflict with, breach, violate or cause a default under any contract, agreement, instrument, order, judgment or decree to which Executive is a party or by which he/she is bound, (ii) Executive is not a party to or bound by any employment agreement, noncompete agreement or confidentiality agreement with any other person or entity and (iii) upon the execution and delivery of this Agreement by the Company, this Agreement shall be the valid and binding obligation of Executive on and after the Effective Date, enforceable in accordance with its terms. Executive hereby acknowledges and represents that he has had the opportunity to consult with independent legal counsel or other advisor of Executive’s choice and has done so regarding Executive’s rights and obligations under this Agreement, that Executive is entering into this Agreement knowingly, voluntarily, and of Executive’s own free will, that Executive is relying on Executive’s own judgment in doing so, and that Executive fully understands the terms and conditions contained herein.

(vii) The Company shall have the right to withhold from any amount payable hereunder any Federal, state and local taxes in order for the Company to satisfy any withholding tax obligation it may have under any applicable law or regulation.

(viii) Parent and its Affiliates shall be third-party beneficiaries of Executive’s covenants and obligations under Section 13 hereof and shall be entitled to enforce such obligations as if a party hereto.

(ix) The covenants and obligations of the Company under Sections 9, 14, 15 and 16 hereof, and the covenants and obligations of Executive under Sections 9, 11, 12, 13, 14, 15 and 16 hereof, shall continue and survive termination of Executive’s employment or any termination of this Agreement.

Exhibit A

RESTRICTED STOCK UNIT AWARD AGREEMENT

THIS AWARD AGREEMENT (this “Agreement”) is entered into as of [_____]1 (the “Agreement Date”) by and between Presidio Production Company, a Delaware corporation (the “Company”), and John Brawley (the “Participant”), pursuant to the terms and conditions of the Presidio Production Company 2025 Equity Incentive Plan (the “Plan”). Capitalized terms not otherwise defined in this Agreement shall have the meanings ascribed to such terms in the Plan.

WHEREAS, the Company has adopted the Plan, which is incorporated herein by reference and made part of this Agreement;

WHEREAS, the Committee has the authority under the Plan to grant Awards to eligible service providers of the Company and its subsidiaries (collectively, the “Company Group”); and

WHEREAS, the Committee has determined that it would be in the best interests of the Company and its stockholders to grant the Award provided for herein to the Participant pursuant to the Plan and this Agreement.

NOW THEREFORE, in consideration of the mutual convents hereinafter set forth, the Company and the Participant agree as follows:

1) Award. Subject to the terms and conditions set forth in the Plan and this Agreement, as of the effective date of the Company’s Form S-8 with respect to the Plan, the Company shall grant the Participant 264,000 Restricted Stock Units (the “RSUs”).

2) Vesting. The RSUs shall vest in substantially equal annual installments on each of the first three (3) anniversaries of the Agreement Date, subject to the Participant’s continued Service on the applicable vesting date, such that one-hundred percent (100%) of the RSUs shall be vested on the third anniversary of the Agreement Date. Any portion of the RSUs that have vested, as set forth in this Section 2, shall be settled within thirty (30) days following the applicable vesting date.

3) Termination. Except as otherwise provided in the Participant’s employment agreement with the Company, upon the termination of the Participant’s Service for any reason, any RSUs that have not vested as of such termination shall be forfeited immediately, automatically and without consideration (unless the Committee, in its sole discretion, determines otherwise).

4) Settlement. Upon settlement of the RSUs, the Company shall deliver to the Participant, for each vested RSU, one share of Common Stock, subject to any terms and conditions set forth in the Plan or imposed by the Committee. No fractional shares of Common Stock shall be delivered and any fractions shall be rounded down.

1 | To be the closing date of the transactions contemplated by the BCA.

5) Dividend Equivalent Rights. If the Company declares and pays a dividend with respect to shares of Common Stock (the dividend paid with respect to a share of Common Stock, the “Dividend Amount”), each outstanding RSU shall be credited with the Dividend Amount (the “Dividend Equivalent”), which Dividend Equivalent shall be paid to the Participant in cash at the same time the Dividend Amounts are paid to holders of shares of Common Stock.

6) Successors and Assigns; No Third Party Beneficiaries. Unless otherwise determined by the Committee, the Participant shall not be permitted to transfer or assign this Agreement or the RSUs, except as expressly permitted under the Plan. The Company may assign this Agreement to an entity controlled by or under common control with the Company or to an entity that acquires all or substantially all of the business, equity or assets of the Company. The provisions of this Agreement shall inure to the benefit of, and be binding upon, the Company Group and its successors and assigns and upon the Participant and the Participant’s heirs, successors, legal representatives and permitted assigns. Nothing in this Agreement, express or implied, is intended to confer on any person other than the Company Group and the Participant, and their respective heirs, successors, legal representatives and permitted assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement.

7) Withholding. As a condition to the granting of the RSUs, the Participant acknowledges and agrees that the Participant is responsible for the payment of income and employment taxes (and any other taxes) payable in connection with the vesting and/or settlement of the RSUs. The Company Group shall have the power and the right to deduct or withhold automatically from any payment or shares of Common Stock deliverable under this Agreement, or require the Participant to remit to the Company Group, the minimum statutory amount to satisfy federal, state, and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of this Agreement (the “Minimum Withholding”) in a form that is reasonably acceptable to the Company (as determined by the Company in its sole discretion). Notwithstanding the foregoing, with respect to any taxes that the Company Group is required to withhold in connection with the vesting and/or settlement of the RSUs, the Company Group shall deduct or withhold automatically from any shares of Common Stock deliverable under this Agreement the number of shares of Common Stock having a fair market value equal to the Minimum Withholding with respect to such taxable event, which retained shares of Common Stock shall fund the payment of such taxes by the Company on the Participant’s behalf.

8) No Rights to Continued Service. The granting of the RSUs shall impose no obligation on any member of the Company Group to continue the Service of the Participant and shall not interfere in any way with the right of any member of the Company Group to terminate such Service.

9) Governing Law; Jurisdiction. This Agreement, and all claims or causes of action or other matters that may be based upon, arise out of or relate to this Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, excluding any conflict or choice of law rule or principle that might otherwise refer construction or interpretation thereof to the substantive laws of another jurisdiction. The Participant irrevocably waives any objection which it may have to the laying of venue of the aforesaid actions or proceedings arising out of or in connection with this Agreement in the courts of the State of Delaware and further irrevocably waives and agrees not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum. The Participant agrees that service of process upon the Participant in any action shall be effective if notice is delivered to the address or facsimile of the Participant set forth on the books of the Company or any other address or facsimile number as the Participant may hereafter specify for such purpose to the Company.

10) WAIVER OF JURY TRIAL. IF PERMITTED BY APPLICABLE LAW, EACH PARTY HERETO IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING (INCLUDING COUNTERCLAIMS) RELATING TO OR ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE TRANSACTIONS OR RELATIONSHIPS HEREBY CONTEMPLATED OR OTHERWISE IN CONNECTION WITH THE ENFORCEMENT OF ANY RIGHTS OR OBLIGATIONS HEREUNDER.

11) Compliance with Section 409A of the Code. Notwithstanding any other provision of this Agreement to the contrary, the Company intends that the RSUs satisfy an exemption from, or comply with, the requirements of Section 409A of the Code (“Section 409A”). This Agreement shall be interpreted in accordance with that intent, such that there are no adverse tax consequences, interest or penalties under Section 409A as a result of the RSUs. In no event whatsoever will any member of the Company Group or any of their respective directors, officers, agents, attorneys, employees, shareholders, investors, managers, fiduciaries, successors or assigns be liable for any additional tax, interest or penalties that may be imposed on the Participant under Section 409A or any damages for failing to comply with Section 409A.

12) No Guarantees Regarding Tax Treatment. The Participant (or the Participant’s beneficiaries) shall be responsible for all taxes with respect to the RSUs. The Board and the Company make no guarantees regarding the tax treatment of the RSUs. Neither the Board nor the Company has any obligation to take any action to prevent the assessment of any tax under Section 409A or Section 457A of the Code or otherwise.

13) Notices. Any notice required or permitted under this Agreement shall be deemed given when delivered personally, or when deposited in the regular mail, postage prepaid, addressed, as appropriate, to the Participant at the last address specified in the Participant’s employment records (or such other address as the Participant may designate in writing to the Company), or to the Company’s headquarters, Attention: General Counsel, or such other address as the Company may designate in writing to the Participant.

14) No Effect on Compensation. The amount of any compensation the Participant receives pursuant to this Agreement shall not constitute includable compensation for purposes of determining the amount of benefits to which the Participant is entitled to under any other compensation or benefit plan or program of the Company Group, including, without limitation, under any pension or severance benefits plan, except to the extent specifically provided by the terms of any such plan or as otherwise expressly required under applicable law.

15) Failure to Enforce Not a Waiver. The failure of the Company to enforce at any time any provision of this Agreement shall in no way be construed to be a waiver of such provision or of any other provision hereof.

16) Recoupment/Clawback. Notwithstanding any other provision in the Plan or this Agreement to the contrary, any amounts paid (in cash or non-cash) to the Participant under this Agreement that are subject to recovery under any current or future law, government regulation, stock exchange listing requirement, or policy of the Company Group (“Company Policy”), will be recouped and recovered by the Company pursuant to such law, government regulation, stock exchange listing requirement, or Company Policy unless such Company Policy violates the laws of the State of Delaware.

17) Amendments. Subject to the terms of the Plan, the Board may amend, alter, suspend, discontinue or terminate this Agreement, the Plan, or any portion thereof at any time, in its sole discretion; provided, that no action taken by the Board shall adversely affect in any material respect any rights granted to the Participant under this Agreement (other than as the Board deems necessary to comply with applicable law) without the Participant’s written consent. No amendment or modification of any term of this Agreement shall be effective unless signed in writing by or on behalf of the Company and, if required, the Participant, and made in accordance with the terms of the Plan.

18) Severability. The provisions of this Agreement are severable and the invalidity of any one or more provisions shall not affect the validity of any other provision. In the event that a court of competent jurisdiction shall determine that any provision of this Agreement or the application thereof is unenforceable in whole or in part because of the duration or scope thereof, the parties hereto agree that said court in making such determination shall have the power to reduce the duration and scope of such provision to the extent necessary to make it enforceable, and that the Agreement in its reduced form shall be valid and enforceable to the full extent permitted by law.

19) Entire Agreement. This Agreement and the Plan constitute the entire agreement and understanding among the parties hereto in respect of the subject matter hereof and supersede all prior and contemporaneous arrangements, agreements and understandings, whether oral or written and whether express or implied, and whether in term sheets, presentations or otherwise, among the parties hereto, or between any of them, with respect to the subject matter hereof.

20) Authority. The Committee has complete authority and discretion to determine Awards, and to interpret and construe the terms of the Plan and this Agreement. The determination of the Committee as to any matter relating to the interpretation or construction of the Plan or this Agreement shall be final, binding and conclusive on all parties.

21) Rights as a Stockholder. The Participant shall have no rights as a stockholder of the Company with respect to any shares of Common Stock underlying or relating to any Award until the Common Stock is issued to the Participant, as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company.

22) Signature in Counterparts. This Agreement may be signed in counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Facsimile and pdf e-mail signatures shall have the same legal effect as manual signatures.

23) Electronic Delivery. The Company may, in its sole discretion, decide to deliver this Agreement by electronic means. The Participant hereby consents to receive this Agreement by electronic delivery and agrees to sign this Agreement by acknowledgment through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

Exhibit B

GENERAL RELEASE

I, [EXECUTIVE], in consideration of and subject to the performance by Presidio Employee Co. LLC (the “Company”), of its obligations under Section 9(a) of the Employment Agreement, dated as of August 5, 2025, between the undersigned and the Company (the “Agreement”), do hereby release and forever discharge as of the date hereof the Company and its subsidiaries, parents, investors, and Affiliates and all present, former and future members, managers, directors, officers, employees, agents, attorneys, representatives, trustees, employee benefit plans (including any administrators or fiduciaries of such plans), shareholders, lenders, creditors, predecessors, successors and assigns of the Company and its subsidiaries and Affiliates, each individually and in their representative capacities, and its and their respective direct or indirect owners (collectively, including the Company, the “Released Parties”) to the extent provided below (this “General Release”). The Released Parties are intended to be third-party beneficiaries of this General Release, and this General Release may be enforced by each of them in accordance with the terms hereof in respect of the rights granted to such Released Parties hereunder. Terms used herein but not otherwise defined shall have the meanings given to them in the Agreement.

| 1. | I understand that any payments or benefits paid or granted to me under Section 9(a) of the Agreement represent, in part, consideration for signing this General Release and are not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive the payments and benefits specified in Section 9(a) of the Agreement unless I execute this General Release and do not revoke this General Release within the time period permitted hereafter. Such payments and benefits will not be considered compensation for purposes of any employee benefit plan, program, policy or arrangement maintained or hereafter established by the Company or its Affiliates.

| 2. | Except as provided in paragraphs 4 and 5 below and except for the provisions of the Agreement which expressly survive the termination of my employment with the Company, I hereby knowingly and voluntarily, unconditionally and irrevocably, (for myself, my spouse, my heirs, executors, administrators, beneficiaries, representatives, successors and assigns (collectively, the “Releasing Parties”)) release and forever discharge the Company and the other Released Parties from any and all claims, suits, controversies, actions, agreements, contracts, grievances, causes of action, claims, cross-claims, counter-claims, demands, debts, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys’ fees, expenses, judgments, liabilities, losses, obligations, rights or suits of any nature whatsoever in law and in equity, both past and present (through the date that this General Release is signed by me), in any jurisdiction, and whether known or unknown, suspected, or claimed against the Company or any of the Released Parties which the Releasing Parties had, have or may have against each and all of the Released Parties, by reason of any actual or alleged act, event, occurrence, omission, practice or other matter whatsoever from the beginning of time up to and including the date that I sign this General Release (except as otherwise expressly set forth in this Agreement). These claims include, but are not limited to: (a) any and all claims for compensation, wages, commissions, bonuses, stock options, deferred compensation, other monetary or equitable relief, vacation, personal or sick time, other fringe benefits, or attorney’s fees; (b) any and all claims based on violations of Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1866 and 1871, the Civil Rights Act of 1991, the Americans with Disabilities Act, the Age Discrimination in Employment Act, the National Labor Relations Act, the Employee Retirement Income Security Act, the Family and Medical Leave Act, the Equal Pay Act, the Older Worker’s Benefit Protection Act, Title 42 U.S.C. § 1981, the Worker Adjustment Retraining and Notification Act, the Occupational Safety and Health Act, the Pregnancy Discrimination Act, the Rehabilitation Act, the Immigration Reform and Control Act, the Consolidated Omnibus Budget Reconciliation Act, the Sarbanes-Oxley Act, Sections 748 (h)(i), 922 (h)(i) and 1057 of the Dodd-Frank Act, the Internal Revenue Code, any applicable Executive Order Programs, the Fair Labor Standards Act, and claims for employment discrimination, harassment, retaliation, wrongful discharge, or breach of public policy; (c) any and all claims under the any and all claims under Texas statutory or common law, including but not limited to claims brought under the Texas Commission on Human Rights Act and the Texas Labor Code, including the Texas Payday Act, the Texas Anti-Retaliation Act, Chapter 21 of the Texas Labor Code, and the Texas Whistleblower Act, (d) any and all claims or causes of action arising under any tort, any equitable theory, any express or implied contract, promissory estoppel, fraud, defamation, emotional distress, infliction of emotional harm, invasion of privacy rights, misrepresentation, or any whistleblower law (all of the foregoing collectively referred to herein as the “Claims”). I intend the release set forth above to be as broad and comprehensive as possible so that the Released Parties shall never be liable, directly or indirectly, to me for any claims, demands, actions, or causes of action of whatsoever nature or character released herein (except as otherwise expressly set forth in this Agreement). This release specifically does not apply to any claims that may arise after its execution.

| 3. | I represent that I have made no assignment or transfer of any right, claim, demand, cause of action, or other matter covered by paragraph 2 above.

| 4. | I acknowledge and agree that my separation from employment with the Company in compliance with the terms of the Agreement shall not serve as the basis for any claim or action (including, without limitation, any claim under the ADEA).

| 5. | I agree that I hereby waive all rights to sue (other than a suit solely seeking to challenge the enforceability of this General Release under the ADEA) or obtain equitable, remedial or punitive relief from any or all Released Parties of any kind whatsoever in respect of any Claim, including, without limitation, reinstatement, back pay, front pay, and any form of injunctive relief. Notwithstanding the above, I further acknowledge that I am not waiving and am not being required to waive any right that cannot be waived under law, including the right to file an administrative charge or participate in an administrative investigation or proceeding; provided, that I disclaim and hereby waive any right to share or participate in any monetary award or personal relief resulting from the prosecution of such charge or investigation or proceeding. Additionally, I am not waiving (i) any rights to any payments, benefits or reimbursements due to me under the Agreement or any equity or other award agreement referred to in the Agreement or otherwise; (ii) any rights to any vested benefits due to me under any employee benefit plans sponsored or maintained by the Company; (iii) any of my rights under [any equity related documents or incentive plans]; (iv) any claim relating to directors’ and officers’ liability insurance coverage or any right of indemnification under the Company’s organizational documents or otherwise; or (v) my ability to pursue workers’ compensation or unemployment benefits.

| 6. | In signing this General Release, I acknowledge and intend that it shall be effective as a bar to each and every one of the Claims hereinabove mentioned or implied. I expressly consent that this General Release shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims (notwithstanding any state or local statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Claims hereinabove mentioned or implied. I acknowledge and agree that this waiver is an essential and material term of this General Release and that without such waiver the Company would not have agreed to the terms of the Agreement. I further agree that in the event the Releasing Parties should bring a Claim seeking damages against the Company, or in the event the Releasing Parties should seek to recover against the Company in any Claim brought by a governmental agency on my behalf, this General Release shall serve as a complete bar and defense to such Claims to the maximum extent permitted by law. I further agree that I am not aware of any pending claim of the type described in paragraph 2 above as of the execution of this General Release.

| 7. | I agree that neither this General Release, nor the furnishing of the consideration for this General Release, shall be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct.

| 8. | I agree that if the Releasing Parties violate this General Release by suing the Company or the other Released Parties, I will pay all costs and expenses of defending against the suit incurred by the Released Parties (other than a suit solely seeking to challenge the enforceability of this General Release under the ADEA), including reasonable attorneys’ fees.

| 9. | I agree that this General Release and the Agreement are confidential and agree not to disclose any information regarding the terms of this General Release or the Agreement, except to my immediate family and any tax, legal or other counsel I have consulted regarding the meaning or effect hereof or as required by law, and I will instruct each of the foregoing not to disclose the same to anyone.

| 10. | Nothing contained in this General Release limits my ability to file a charge or complaint with the Equal Employment Opportunity Commission, the Department of Justice, the Securities and Exchange Commission, Congress, and any agency Inspector General or any other federal, state or local governmental agency or commission (“Government Agencies”). Further, this Agreement does not limit my ability to communicate with any Government Agencies or otherwise participate in any investigation or preceding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. This Agreement does not limit my right to receive an award from a Government Agency for information provided to any Government Agencies. However, I agree that I have waived any right to recover monetary damages or other personal relief, where such rights can be lawfully waived, from the Releases in any action filed by me or by anyone else on my behalf.

| 11. | I acknowledge that I have been notified, in accordance with the Defend Trade Secrets Act of 2016, that I will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or any such disclosure that is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. If I file a lawsuit for retaliation against a Released Party for reporting a suspected violation of law, I may disclose such Released Party’s trade secrets to my attorney and use the trade secret information in the court proceeding if I file any document containing the trade secret under seal, and do not disclose the trade secret, except pursuant to court order.

| 12. | I represent that I am not aware of any claim by the Releasing Parties against the Company or any of the Released Parties, including the claims that are released by this General Release. I acknowledge that, although I may hereafter discover claims or facts in addition to or different than those which I now know or believe to exist with respect to the subject matter of the release set forth in paragraph 2 above and which, if known or suspected at the time of entering into this General Release, may have materially affected this General Release and my decision to enter into it, I intend to provide a complete waiver and release of all Claims based on any facts and circumstances, whether known or unknown, up to and including the date that I sign this General Release.

| 13. | I acknowledge and agree that I am owed no further compensation or benefits arising out of or related to my employment with the Company, other than my right, if I execute this General Release, to the payments set forth in Section 9 of the Agreement or any equity or incentive award agreement to which I am a party and subject to the terms and conditions set forth therein. Notwithstanding anything in this General Release to the contrary, this General Release shall not relinquish, diminish, or in any way affect any rights or claims arising out of any breach by the Company of Section 9 of the Agreement or [any equity or incentive award agreement] to which I am a party after the date hereof.

| 14. | Whenever possible, each provision of this General Release shall be interpreted in, such manner as to be effective and valid under applicable law, but if any provision of this General Release is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, (i) such provision shall be modified to make it valid, legal and enforceable to the maximum extent permitted by law or (ii) if such provision cannot be modified to make it valid, legal and enforceable, such invalidity, illegality or unenforceability shall not affect any other provision or any other jurisdiction, but this General Release shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. I acknowledge and agree that each of the terms, conditions and covenants to which I am subject in this General Release shall be construed for all purposes to be separate and independent from any other terms, conditions and covenants of any of the Released Parties, whether in this Agreement or otherwise, and the existence of any claim by me against the Company or any of the other Released Parties under the Agreement or otherwise, will not excuse my breach of any of the terms, conditions or other covenants contained in this General Release.
