I. Purpose and Background
A. Purpose
The purpose of this memorandum is to provide the Calderwood & Harkness LLP ("C&H") engagement team with a comprehensive map of all advisors currently retained or expected to be retained by Dunmore Energy Holdings Ltd. ("DEH") and its affiliates in connection with the proposed transfer of Production Tax Credits ("PTCs") generated by the Ridgeway Wind Project (as defined below) pursuant to section 6418 of the Internal Revenue Code of 1986, as amended (the "Code" or "IRC"). This memorandum identifies each advisor's role, scope of engagement, key deliverables, and anticipated coordination points with C&H. It further maps the dependencies among the various advisor work streams and proposes a timeline for the scoping phase of C&H's engagement. The goal is to ensure that the engagement team has a clear and unified understanding of who is doing what, where responsibilities overlap, and how the various work products interrelate — thereby minimizing the risk of duplicative effort, inadvertent gaps in coverage, or miscommunication during a transaction of this complexity.
B. Client and Affiliates
The client is Dunmore Energy Holdings Ltd. ("DEH"), an exempted limited company organized under the laws of the Cayman Islands, registered with the Cayman Islands Registrar of Companies under registry number CR-284319. DEH maintains its registered office and principal place of business at 4th Floor, Harbour Place, 103 South Church Street, George Town, Grand Cayman KY1-1002. DEH is a privately held company; Callum Dunmore serves as Chairman of the board and holds an approximately 68% majority equity interest.
DEH's U.S. operations are conducted through Dunmore Renewables Inc. ("DRI"), a Delaware corporation, file number 7491826, headquartered at 900 Bridger Boulevard, Suite 410, Billings, Montana 59101. DRI serves as the direct parent and sole member of the project-level entity described below.
The project company and credit generator is Ridgeway Wind Energy LLC ("RWE" or the "Project Company"), a Delaware limited liability company, file number 7603517. RWE is a disregarded entity for U.S. federal income tax purposes, with DRI as its sole member. RWE owns and operates the Ridgeway Wind Project.
C. The Project
The Ridgeway Wind Project (the "Project") is a 250-megawatt (MW) onshore wind energy generation facility situated on approximately 28,000 acres of leased ranchland located approximately 14 miles northeast of Miles City, Custer County, Montana. The Project consists of 83 wind turbine generators, each with a rated capacity of 3.0 MW, plus one 1.0 MW backup unit, for a total nameplate capacity of 250 MW. Construction of the Project commenced on April 6, 2023, and the Project achieved commercial operations ("COD") on November 14, 2025. The total project cost was approximately $412 million.
The Project's energy output is contracted under a 20-year fixed-price power purchase agreement at $38.50/MWh with Great Plains Municipal Power Authority, and the Project is interconnected to the Midcontinent Independent System Operator ("MISO") grid under a Generator Interconnection Agreement with NorthStar Transmission Holdings LLC (MISO Queue Position J-1147). Construction and term financing was provided by Redstone Capital Bank, N.A. under a Credit Agreement dated March 28, 2023, with an original construction-to-term loan commitment of $288,400,000 (representing approximately 70% of total project cost), of which approximately $271,600,000 in principal remains outstanding as of March 1, 2026.
D. The Proposed Transaction
DEH proposes, through its wholly owned subsidiary chain (DRI as sole member of RWE), to effect a direct transfer election under IRC § 6418 with respect to the PTCs generated by the Project. The prospective buyer of the transferred credits is Pinnacle Atlantic Partners LP ("Pinnacle"), a Delaware limited partnership, file number 7255043, headquartered at 277 Park Row, 18th Floor, New York, New York 10172. Pinnacle is a diversified financial services holding company with a well-established § 6418 credit acquisition program.
The proposed transfer price is $0.92 per $1.00 of credit, representing an 8% discount to face value. Based on an estimated Year 1 PTC of $25,295,655, the estimated Year 1 transfer consideration would be approximately $23,271,803. Over the anticipated 10-year PTC eligibility period (TY2025 through TY2034), the estimated aggregate transfer consideration is approximately $232,760,000, subject to annual true-up based on actual energy production and applicable credit rates.
E. Status of C&H Engagement
The C&H engagement was opened on March 9, 2026, and is currently in the prospective scoping phase. The scoping-phase fee estimate, as communicated to the client, is in the range of $85,000 to $125,000. Should the engagement expand to include the negotiation and execution of definitive transaction documents, the potential full-transaction fee estimate is in the range of $350,000 to $500,000. The engagement letter was executed by Marcus Petrov on behalf of DEH.

IV. Grayson Birch & Co. LLP — Independent Tax Advisor
A. Entity Information
Grayson Birch & Co. LLP 1700 K Street NW, Suite 900 Washington, DC 20006
Grayson Birch & Co. LLP ("Grayson Birch") serves as the independent tax advisor retained by DEH to provide technical tax analysis and support in connection with the PTC eligibility, credit computation, IRS registration, and related matters for the Ridgeway Wind Project.
B. Lead Contact
Howard Ellison, Partner, National Tax — Renewable Energy. Mr. Ellison leads Grayson Birch's engagement and serves as the firm's primary relationship partner for DEH on this matter.
C. Scope of Engagement
Grayson Birch's scope of engagement encompasses the following areas:
1. PTC Eligibility Memorandum. Grayson Birch will prepare a comprehensive memorandum confirming that Ridgeway Wind Energy LLC qualifies as an eligible taxpayer to generate PTCs under IRC § 45 and is eligible to make a transfer election under IRC § 6418. This memorandum will address the threshold requirements for PTC eligibility, including the "beginning of construction" safe harbor (construction start date of April 6, 2023), the placed-in-service requirement (COD of November 14, 2025), and the applicable provisions governing the generation of PTCs by a disregarded entity whose regarded owner (DRI) is a U.S. corporation.
2. Credit Rate Analysis. Grayson Birch will verify the applicable credit rate for the PTCs generated by the Project, including:
(a) The base credit rate of $0.0055 per kilowatt-hour, as adjusted for inflation for calendar year 2025;
(b) The 5x bonus credit multiplier applicable to facilities that satisfy the prevailing wage and apprenticeship requirements under IRC § 45(b)(6), yielding a base credit rate (after multiplier) of $0.0275 per kWh (inflation-adjusted);
(c) The 10% energy community bonus credit adder under IRC § 45(b)(11)(B), based on the eligibility of Custer County, Montana as a census tract with historical fossil fuel employment meeting the statutory threshold, yielding an additional $0.00275 per kWh; and
(d) The resulting effective credit rate of $0.03025 per kWh for the initial credit year, subject to annual inflation adjustments.
3. Cost Segregation Analysis. Grayson Birch will conduct a cost segregation analysis for the Ridgeway Wind Project based on the total project cost of approximately $412 million. While the cost segregation analysis is principally relevant to DRI's own tax position (depreciation and cost recovery), it may also be relevant to the buyer's diligence in connection with the § 6418 transfer.
4. IRS Pre-Filing Registration. Grayson Birch will manage the IRS pre-filing registration process under Treas. Reg. § 1.6418-4 via the IRS Energy Credits Online portal. Registration for TY2025 is currently pending. The procurement of a valid registration number is a prerequisite to completing the transfer election, as the transfer is not valid unless the eligible taxpayer has obtained a registration number with respect to each applicable tax credit and provided it to the transferee taxpayer.
5. Recapture Risk Analysis. Grayson Birch will analyze the substantive tax risks of PTC recapture or disallowance under IRC § 45, including the events or circumstances that could trigger a credit reduction or clawback, the applicable recapture period, and the quantum of potential recapture exposure.
6. Tax Treatment of Transfer Consideration. Grayson Birch will confirm that, under IRC § 6418(b), the transfer consideration paid by the buyer is not includible in the gross income of the seller/transferor and is treated as a non-taxable adjustment to the tax liability of the buyer/transferee.
7. Annual PTC Computation Support. Grayson Birch will provide annual computation support for the PTC amount for each taxable year during the 10-year credit period (TY2025 through TY2034). The estimated Year 1 PTC computation is as follows:
• Nameplate capacity: 250 MW
• Hours per year: 8,760
• P50 net capacity factor: 38.2%
• Annual generation: 250,000 kW × 8,760 hrs × 0.382 = 836,220,000 kWh
• Effective credit rate: $0.03025/kWh
• Estimated Year 1 PTC: 836,220,000 kWh × $0.03025/kWh = $25,295,655
D. Key Deliverables
1. PTC eligibility and transfer election memorandum
2. Cost segregation study report
3. IRS registration filing support and procurement of registration number for TY2025
4. Annual credit calculation certification for each taxable year TY2025 through TY2034
E. Coordination with C&H
The coordination between C&H and Grayson Birch is among the most critical interrelationships in this transaction, as both firms will be providing overlapping but distinct tax-related analysis. The following coordination points have been identified:
1. Introduction and Initial Contact. C&H is to request an introduction to Howard Ellison through Marcus Petrov, per Sylvia Hartwell's email of March 10, 2026. An initial coordination call between C&H and Grayson Birch should be scheduled during the week of March 18, 2026 to delineate scope and establish working protocols.
2. Reliance on Grayson Birch Analysis. C&H's structuring memorandum will rely on Grayson Birch's PTC eligibility analysis as the authoritative source for credit computation inputs, bonus credit qualification determinations, and technical eligibility conclusions. C&H will not independently replicate Grayson Birch's technical tax eligibility analysis but will instead cross-reference and incorporate Grayson Birch's conclusions as inputs to C&H's legal structuring analysis.
3. Delineation of Overlapping Scope. The division of labor between the two firms should be clearly understood by both engagement teams:
(a) C&H leads on: legal structuring of the § 6418 transfer, negotiation and drafting of the Transfer Agreement and all ancillary documentation, lender consent analysis and negotiation, escrow agreement drafting, and coordination with counterparty counsel (HL&S).
(b) Grayson Birch leads on: technical tax eligibility analysis under IRC § 45, credit rate computation and verification (including bonus credit qualification under prevailing wage/apprenticeship and energy community provisions), IRS registration process under Treas. Reg. § 1.6418-4, cost segregation study, and annual credit calculation certification.
4. Review of Draft PTC Eligibility Memo. Grayson Birch has agreed (or is expected to agree) to provide a draft of the PTC eligibility memorandum to C&H for review prior to finalization. C&H's review will focus on ensuring that the eligibility conclusions support the legal positions to be taken in the Transfer Agreement and that the memorandum adequately addresses issues that may arise in negotiations with Pinnacle and HL&S.
5. Coordination on Recapture Risk. The recapture risk analysis involves both substantive tax analysis and contractual risk allocation. Grayson Birch will address the substantive tax recapture triggers and the quantum of potential recapture exposure, while C&H will address the contractual allocation of recapture risk between seller and buyer in the Transfer Agreement, including indemnification provisions, the 15% holdback mechanics, and the insurance backstop.
6. Cayman-to-U.S. Entity Chain Issues. The fact that DEH is a Cayman Islands exempted limited company raises potential withholding or tax characterization issues with respect to the flow of transfer consideration from Pinnacle to RWE and upstream through DRI to DEH. C&H and Grayson Birch will need to coordinate their respective analyses of these issues. Specifically, C&H will need Grayson Birch's guidance on whether the § 6418 transfer consideration, which is not gross income to the seller, could nonetheless give rise to withholding obligations or other tax consequences at any point in the entity chain from RWE to DRI to DEH.
V. Meridian Technical Advisors LLC — Independent Engineer
A. Entity Information
Meridian Technical Advisors LLC 555 Capitol Mall, Suite 1200 Sacramento, California 95814
Meridian Technical Advisors LLC ("Meridian") serves as the independent engineer retained by DEH to provide technical engineering analysis, energy production estimates, and project certification services for the Ridgeway Wind Project.
B. Lead Contact
Dr. Paul Marlowe Commerce Bank, PE. Dr. Marlowe Commerce Bank is a licensed professional engineer and leads Meridian's engagement with DEH for the Ridgeway Wind Project.
C. Scope of Engagement
Meridian's scope encompasses the following:
1. Energy Production Estimate. Meridian has prepared (or is in the process of finalizing) an Independent Engineer's Report establishing the expected annual energy production of the Project. The key parameters of the energy production estimate are as follows:
• Nameplate capacity: 250 MW (83 turbines × 3.0 MW rated capacity, plus one 1.0 MW backup unit)
• P50 net capacity factor ("NCF"): 38.2%
• Estimated annual generation at P50: 836,220,000 kWh
The P50 estimate represents the level of annual energy production that has a 50% probability of being exceeded in any given year. The Independent Engineer's Report will also include P75 and P90 estimates for risk-adjusted production scenarios, which may be relevant to Pinnacle's diligence and the annual true-up mechanics of the Transfer Agreement.
2. Turbine Performance Report. Meridian will provide a turbine performance assessment evaluating the operational performance of the 83 primary turbine generators and the backup unit, including availability statistics, performance curves, and any material deficiencies or warranty claims.
3. COD Certification. Meridian will issue (or has issued) a COD Certificate confirming the commercial operations date of November 14, 2025. This certification is critical for establishing the beginning of the 10-year PTC eligibility period.
4. Construction Start Certification. Meridian will also confirm or has confirmed the construction start date of April 6, 2023, which is relevant to the "beginning of construction" safe harbor under IRC § 45.
D. Key Deliverables
1. Independent Engineer's Report (energy production estimate, including P50, P75, and P90 scenarios)
2. COD Certificate (confirming commercial operations date of November 14, 2025)
3. Turbine performance assessment
E. Coordination with C&H
1. Document Request. C&H is to request copies of all Meridian reports through Marcus Petrov and Angela Whitfield, per Sylvia Hartwell's document request email of March 10, 2026. The engagement team should follow up promptly if these reports have not been received by the week of March 25, 2026.
2. Input to Economic Model. Meridian's energy production estimate is a foundational input to Garrett Simmons' PTC Credit Calculation and Transfer Economics Model. Specifically, the P50 annual generation figure of 836,220,000 kWh, when multiplied by the effective credit rate of $0.03025/kWh (as determined by Grayson Birch), yields the estimated Year 1 PTC of $25,295,655. This estimate in turn drives the estimated Year 1 transfer consideration of $23,271,803 (at a $0.92/$1.00 transfer price) and the estimated Year 1 holdback of $3,490,770 (15% of transfer consideration).
3. COD Certification — PTC Eligibility Period. Meridian's COD certification establishing November 14, 2025 as the commercial operations date is critical for determining the commencement and duration of the 10-year PTC eligibility period (TY2025 through TY2034). This certification will be relied upon by Grayson Birch in its PTC eligibility memorandum and will be a key diligence deliverable for Pinnacle and HL&S.
4. Buyer Diligence. The Meridian Independent Engineer's Report will be one of the most important diligence deliverables requested by Pinnacle Atlantic Partners LP and its counsel HL&S. As a sophisticated credit buyer with approximately $1.2 billion in prior credit purchases, Pinnacle will almost certainly require access to the full Meridian report, including all underlying assumptions, data sets, and sensitivity analyses.
5. Reliance Letter. C&H will need to review Meridian's reliance letter and the scope of reliance permissions extended to the buyer. It is standard market practice in § 6418 transfer transactions for the buyer to require a reliance letter from the seller's independent engineer, permitting the buyer to rely on the Independent Engineer's Report for purposes of its own investment analysis and credit underwriting. C&H should coordinate with Meridian and the client to ensure that the scope of reliance permissions is acceptable and does not expose DEH or Meridian to unintended liability.
VI. Corbin Hale & Associates Inc. — Insurance Broker
A. Entity Information
Corbin Hale & Associates Inc. 200 South Wacker Drive, Suite 2800 Chicago, Illinois 60606
Corbin Hale & Associates Inc. ("Corbin Hale") serves as the insurance broker retained by DEH to advise on and broker the placement of tax credit recapture insurance for the Ridgeway Wind PTC transfer transaction.
B. Lead Contact
Steven Rask. Mr. Rask leads the Corbin Hale team advising DEH on insurance matters related to the proposed transaction.
C. Scope of Engagement
1. Brokering Tax Credit Recapture Insurance. Corbin Hale is responsible for sourcing and placing a tax credit recapture insurance policy with Northfield Specialty Insurance Co. (80 Pine Street, New York, New York 10005). This policy is intended to backstop DEH's (and RWE's) recapture and disallowance indemnification obligations to Pinnacle under the Transfer Agreement. In the event that the PTCs transferred to Pinnacle are subsequently recaptured or disallowed by the Internal Revenue Service, the insurance policy would respond to cover a portion or all of the resulting loss, thereby providing an additional layer of credit support beyond the 15% indemnity holdback.
2. Advising on Transfer Indemnity Insurance Coverage. Corbin Hale will advise DEH on the scope, limits, exclusions, and premium of the proposed insurance coverage, including the specific risks to be insured (recapture events, credit disallowance events, prevailing wage and apprenticeship compliance failures, energy community disqualification), the policy limits relative to the indemnification obligations in the Transfer Agreement, and the cost-effectiveness of the coverage.
3. Evaluating Buyer-Side Insurance. Corbin Hale will evaluate whether Pinnacle may require buyer-side insurance as an additional or alternative credit support mechanism. In some § 6418 transfer transactions, the buyer independently procures its own recapture insurance as a supplement to the seller's indemnification obligations. Corbin Hale will advise DEH on whether such a structure is being contemplated by Pinnacle and, if so, how the seller-side and buyer-side policies should be coordinated.
D. Key Deliverables
1. Insurance market summary and preliminary indication of terms from Northfield Specialty Insurance Co.
2. Draft insurance specifications and coverage outline
3. Final bound policy (if the transaction proceeds to the definitive documentation stage)
E. Coordination with C&H
1. Defining Indemnification Scope. C&H will be responsible for defining the scope of the indemnification obligations in the Transfer Agreement that the insurance policy must backstop. This scope definition will be a critical input to Corbin Hale's and Northfield's underwriting process. The indemnification obligations are expected to cover, at a minimum: (a) PTC recapture events under IRC § 45, (b) credit disallowance events resulting from seller misrepresentations or failure to satisfy eligibility requirements, (c) prevailing wage and apprenticeship compliance failures that result in loss of the 5x bonus credit multiplier, and (d) energy community disqualification events that result in loss of the 10% bonus credit adder.
2. Policy Form Review. C&H will review the insurance policy form once it is available from Northfield, to ensure that the policy terms align with the indemnification provisions of the Transfer Agreement. Key areas of review will include the definitions of covered events, the policy limits relative to the indemnification cap, the treatment of the holdback as a first-loss layer, and any exclusions that could create gaps in coverage.
3. Holdback and Insurance Coordination. C&H will coordinate with Steven Rask and Corbin Hale on the interplay between the insurance coverage and the 15% indemnity holdback. Pinnacle's indicative term sheet contemplates that the recapture insurance from Northfield will serve as a backstop to the indemnity holdback (estimated at $3,490,770 for Year 1, to be deposited with Commonwealth Fiduciary Trust Company). The precise mechanics of this backstop — including whether insurance responds only after the holdback is exhausted, or whether the holdback and insurance respond concurrently — will be a key negotiation point.
4. Indemnification Cap Negotiation. The scope and limits of the insurance coverage will directly influence C&H's negotiation position on capping the seller's total indemnification exposure under the Transfer Agreement. If robust insurance coverage is available at acceptable premium levels, DEH may be able to negotiate a lower overall indemnification cap or a shorter survival period for indemnification obligations.
VII. Northfield Specialty Insurance Co. — Tax Credit Recapture Insurer
A. Entity Information
Northfield Specialty Insurance Co. 80 Pine Street New York, New York 10005
Northfield Specialty Insurance Co. ("Northfield") is the prospective provider of the tax credit recapture insurance policy for the Ridgeway Wind PTC transfer transaction. Northfield is being engaged by DEH through Corbin Hale & Associates Inc. as insurance broker.
B. Lead Contact
To be assigned. Corbin Hale is managing the initial relationship with Northfield, and a designated underwriter or coverage counsel has not yet been identified. C&H anticipates that a lead contact will be assigned once the underwriting process begins in earnest, which is expected to occur in mid-April 2026.
C. Role and Scope
Northfield's role is to issue a tax credit recapture insurance policy covering the risk of PTC recapture or disallowance with respect to the PTCs transferred by RWE to Pinnacle under the IRC § 6418 transfer election. The policy is intended to cover events under IRC § 45 that would trigger a credit reduction or clawback, including but not limited to:
(a) Recapture events arising from changes in the ownership, use, or operational status of the Project during the PTC eligibility period;
(b) Credit disallowance events arising from a determination by the IRS that RWE or the Project did not satisfy one or more eligibility requirements for the generation of PTCs;
(c) Loss of the 5x bonus credit multiplier due to failure to satisfy prevailing wage and apprenticeship requirements under IRC § 45(b)(6); and
(d) Loss of the 10% energy community bonus credit adder due to disqualification of the Project's location under IRC § 45(b)(11)(B).
The policy will serve as additional credit support complementing the 15% indemnity holdback escrowed at Commonwealth Fiduciary Trust Company. It is expected that the policy will be structured as an excess layer above the holdback, although the precise layering will be subject to negotiation.
D. Coordination with C&H
1. Policy Form Review. C&H will review and comment on the insurance policy form once it is available from Northfield. The review will focus on ensuring that the policy definitions, triggers, exclusions, and payment mechanics are fully consistent with the indemnification provisions of the Transfer Agreement.
2. Alignment with Transfer Agreement. C&H will ensure that the insurance policy coordinates with the indemnification cap, holdback release mechanics, and definitions of "disallowance events" in the Transfer Agreement. Any discrepancies between the policy language and the Transfer Agreement language could create gaps in coverage or unintended exposure for the seller.
3. Underwriting Disclosures and Privilege. The Northfield underwriting process may require disclosure of Grayson Birch's PTC eligibility memorandum, Meridian's Independent Engineer's Report, and potentially other materials that may be subject to attorney-client privilege or work product protection. C&H will manage privilege and reliance considerations in connection with any such disclosures, including evaluating whether disclosures to Northfield waive any applicable privilege and, if so, whether appropriate confidentiality or non-waiver agreements should be put in place.
VIII. Commonwealth Fiduciary Trust Company — Escrow Agent
A. Entity Information
Commonwealth Fiduciary Trust Company One Liberty Place 1650 Market Street, Suite 3600 Philadelphia, Pennsylvania 19103
Commonwealth Fiduciary Trust Company ("Commonwealth Fiduciary") is the prospective escrow agent for the indemnity holdback in connection with the Ridgeway Wind PTC transfer transaction.
B. Lead Contact
To be assigned. Commonwealth Fiduciary's designated account officer has not yet been identified. Garrett Simmons will serve as the primary C&H contact for Commonwealth Fiduciary once the engagement progresses to the escrow agreement negotiation stage.
C. Retention Structure
Commonwealth Fiduciary is anticipated to be jointly appointed by Ridgeway Wind Energy LLC (as seller/transferor) and Pinnacle Atlantic Partners LP (as buyer/transferee). Joint appointment is standard practice for escrow agents in § 6418 transfer transactions, as the escrow agent must take instructions from both parties under specified circumstances.
D. Scope of Engagement
1. Holdback Deposits. Commonwealth Fiduciary will hold 15% of each annual transfer consideration payment in an escrow account. Based on the estimated Year 1 transfer consideration of $23,271,803, the Year 1 holdback deposit would be $3,490,770. The holdback amount for subsequent years will be determined based on actual PTC generation and the applicable transfer price.
2. Release Period. Each holdback deposit is subject to a 36-month release period commencing from the date of each deposit. Amounts not subject to pending claims will be released to the seller upon expiration of the 36-month period.
3. Release and Disbursement Mechanics. The specific release and disbursement mechanics will be set forth in the Escrow Agreement, which is to be negotiated among the parties. These mechanics are expected to include provisions for: (a) scheduled release of unclaimed holdback amounts after the 36-month release period, (b) procedures for submission and resolution of claims by the buyer against holdback amounts, (c) procedures for disbursement of holdback amounts to the buyer in satisfaction of valid claims, and (d) dispute resolution procedures for contested claims.
4. Claims Resolution. The Escrow Agreement will include provisions governing the resolution of claims against holdback amounts, including notice requirements, cure periods, and the circumstances under which the escrow agent is authorized to disburse funds to the buyer without the seller's consent.
E. Key Deliverables
1. Escrow Agreement (to be drafted and negotiated by C&H on behalf of DEH/Ridgeway Wind if the engagement expands to the full transaction phase)
2. Periodic escrow account statements reflecting deposits, releases, claims, and balances
F. Coordination with C&H
1. Escrow Agreement Drafting. C&H will be responsible for drafting or negotiating the Escrow Agreement on behalf of DEH and RWE. The Escrow Agreement will need to be coordinated with the Transfer Agreement, as the holdback and release mechanics in the Escrow Agreement must be fully consistent with the indemnification and holdback provisions of the Transfer Agreement.
2. Conforming Standard Terms. Commonwealth Fiduciary is expected to propose its standard form escrow terms as a starting point for negotiation. C&H will review these standard terms and negotiate any amendments necessary to conform the escrow terms to the holdback and release mechanics agreed upon by the parties in the Transfer Agreement.
3. Coordination with Counterparty Counsel. The Escrow Agreement will be a tri-party document among the seller (RWE), the buyer (Pinnacle), and the escrow agent (Commonwealth Fiduciary). C&H will coordinate with Hargrove, Liddell & Strauss LLP on the buyer's requirements for the Escrow Agreement, including the joint escrow instructions that will govern the escrow agent's actions.
4. Capacity and Fee Schedule. C&H should confirm, as an early action item, that Commonwealth Fiduciary has the capacity to serve as escrow agent for a transaction of this size and duration, and should obtain Commonwealth Fiduciary's fee schedule for the engagement team's review and the client's approval.
IX. Counterparty Counsel — Hargrove, Liddell & Strauss LLP
A. Entity Information
Hargrove, Liddell & Strauss LLP 400 Lexington Avenue, Suite 3200 New York, New York 10170
Hargrove, Liddell & Strauss LLP ("HL&S") serves as outside legal counsel to Pinnacle Atlantic Partners LP in connection with the proposed IRC § 6418 PTC transfer transaction.
B. Key Personnel
C. Client — Pinnacle Atlantic Partners LP
Pinnacle Atlantic Partners LP ("Pinnacle") is a Delaware limited partnership, file number 7255043, headquartered at 277 Park Row, 18th Floor, New York, New York 10172. Pinnacle is a diversified financial services holding company with an average annual federal income tax liability of approximately $480 million (based on a three-year average). Pinnacle has an active IRC § 6418 credit acquisition program and has completed approximately $1.2 billion in prior credit purchases across solar, wind, and battery storage projects. Pinnacle's experience and sophistication as a repeat buyer in the § 6418 market is a significant factor in the proposed transaction, as it suggests that Pinnacle and HL&S will have well-developed views on transaction structure, diligence requirements, and documentation standards.
The key Pinnacle contacts for this transaction are:
• Diana Calloway, Managing Partner
• Jonathan Frey, Head of Tax Credit Investments
• Priya Sandoval, SVP, Structuring
D. Role in the Transaction
HL&S serves as outside counsel to Pinnacle in its capacity as the prospective buyer of PTCs in the proposed § 6418 transfer. HL&S is responsible for advising Pinnacle on all legal and tax aspects of the credit acquisition, including negotiation and drafting of the Transfer Agreement (from the buyer's perspective), delivery of a tax opinion to Pinnacle on credit transferability and usability, and review of seller diligence materials.
E. Anticipated HL&S Deliverables to Pinnacle
1. Transfer Agreement. HL&S is expected to prepare or provide Pinnacle's preferred form of Transfer Agreement. C&H has inquired, via Robert Jansen's email of March 18, 2026 to Catherine Yoon, whether Pinnacle has a preferred form. Given Pinnacle's extensive track record in the § 6418 market ($1.2 billion in prior purchases), it is likely that Pinnacle and HL&S have a well-developed buyer-form Transfer Agreement that they will seek to use as the starting point for negotiation.
2. Tax Opinion to Pinnacle. HL&S will provide a tax opinion to Pinnacle confirming that the transferred PTCs are valid and usable by Pinnacle as a credit against its federal income tax liability, and that the transfer consideration is treated as a non-taxable adjustment to Pinnacle's tax liability under IRC § 6418(b).
