Business Description: Penterra Pharmaceuticals Corp. is a mid-cap specialty pharmaceutical company headquartered in Princeton, New Jersey. Penterra maintains a commercial portfolio of twelve (12) marketed products spanning the oncology, immunology, and rare disease therapeutic areas. The company has historically derived a significant portion of its revenue from its oncology franchise, supported by a growing immunology portfolio. Penterra's research and development efforts have been principally directed toward immuno-oncology, where the company has invested substantial capital in building an internal pipeline of novel therapeutic candidates. Notably, Penterra's immuno-oncology pipeline experienced a material setback in November 2023, when the company announced a Phase III futility analysis for its lead internal candidate, PPC-0921, a programmed death-ligand 1 (PD-L1) inhibitor being evaluated in combination therapy for advanced non-small cell lung cancer. The failure of PPC-0921 created a significant gap in Penterra's late-stage oncology pipeline and has been identified by Penterra's management and board of directors as a strategic imperative requiring prompt remediation through external business development activities. The proposed acquisition of Veridian Biosciences, Inc. described in this memorandum represents Penterra's primary strategic response to this pipeline shortfall.

Penterra is an existing client of the firm. Calderwood & Harkness LLP has previously represented Penterra in connection with various corporate and securities matters, including its 2021 public offering of 5.00% Senior Notes due 2031 and its 2022 acquisition of certain commercial assets from Helios Therapeutics, Inc. The firm's prior representations of Penterra are reflected on the firm's client database, and no adverse issues or concerns have been identified in connection with the proposed new engagement.

2. Matter Description

2.1 Nature of Matter

This matter involves the proposed acquisition by Penterra Pharmaceuticals Corp. ("Penterra" or the "Buyer") of one hundred percent (100%) of the outstanding capital stock of Veridian Biosciences, Inc. ("Veridian" or the "Target"), a privately held clinical-stage biotechnology company. The transaction is anticipated to be structured as an all-cash stock purchase, pursuant to which Penterra (or a wholly owned subsidiary of Penterra formed for the purpose of the acquisition) will acquire all issued and outstanding shares of common stock and preferred stock of Veridian from the existing stockholders of Veridian (collectively, the "Sellers").

2.2 Transaction Type

Stock Purchase (all-cash consideration). No stock-for-stock exchange, merger structure, or tender offer is currently contemplated, although the final structure remains subject to further analysis and negotiation.

2.3 Anticipated Purchase Price

The anticipated aggregate purchase price for 100% of the outstanding capital stock of Veridian is approximately $850 million to $950 million, based on preliminary discussions between the parties and their respective financial advisors. The final purchase price remains subject to negotiation and is expected to be determined following the completion of due diligence, valuation analysis by Penterra's financial advisor, Garrison Zanthor & Co., LLC, and arm's-length negotiations with the Sellers and their advisors. The purchase price may include customary adjustments for cash, indebtedness, working capital, and transaction expenses at closing, as well as potential contingent consideration (e.g., milestone-based earnout payments tied to regulatory or commercial achievements), the inclusion and structure of which are currently under discussion.

2.4 Target Company Information

Full Legal Name: Veridian Biosciences, Inc.

Short Name / Abbreviations: Veridian; VBI

Entity Type: Corporation, incorporated in the State of Delaware; privately held

Employer Identification Number (EIN): 84-2193047

Principal Office:

550 Gateway Drive Cambridge, Massachusetts 02142

Delaware Registered Agent:

Tidewater Registered Agents LLC 838 Walker Road, Suite 21-2 Dover, Delaware 19904

Key Management:

• Dr. Julian Marek, Chief Executive Officer & Co-Founder

• Dr. Priya Chandrasekaran, Chief Scientific Officer & Co-Founder

• Steven R. Kessler, Chief Financial Officer

• Rachel Stein-Goldberg, General Counsel

Background: Veridian Biosciences, Inc. was founded in 2016 by Dr. Julian Marek and Dr. Priya Chandrasekaran, both of whom are leading researchers in the field of bispecific antibody therapeutics. Veridian is a clinical-stage biotechnology company focused on the development of immuno-oncology therapeutics leveraging its proprietary T-cell engager platform, known as "VeriTCE." The VeriTCE platform is designed to generate bispecific antibodies capable of simultaneously engaging tumor-associated antigens and T-cell surface receptors, thereby redirecting the patient's own immune cells to selectively target and destroy cancer cells.

Veridian's lead product candidate is VRD-4187, a bispecific T-cell engager targeting DLL3-expressing tumors, with a principal focus on the treatment of small cell lung cancer ("SCLC"). VRD-4187 is currently being evaluated in a multi-center, open-label Phase II clinical trial (IND 154832; ClinicalTrials.gov Identifier: NCT05837291). Preliminary Phase I/Ib data presented at the American Society of Clinical Oncology (ASCO) Annual Meeting in June 2023 demonstrated encouraging signs of clinical activity, including a confirmed objective response rate (ORR) of approximately 34% in heavily pre-treated SCLC patients, with a manageable safety profile. These data constitute a significant component of the Target's current valuation.

Veridian has no product revenue to date. The company has been funded entirely through venture capital and growth equity financing, having raised approximately $420 million in aggregate across four rounds of equity financing (Series A through Series D). As of the most recent available information, Veridian employs approximately 148 full-time employees, the majority of whom are engaged in research and development, clinical operations, and regulatory affairs at its Cambridge, Massachusetts headquarters.

2.5 Strategic Rationale

The proposed acquisition of Veridian is intended to serve as a critical strategic initiative for Penterra in the wake of the Phase III futility analysis for PPC-0921 announced in November 2023. The failure of PPC-0921 eliminated Penterra's most advanced internal immuno-oncology candidate and created a significant gap in the company's late-stage development pipeline. Penterra's board of directors and senior management team have determined that the acquisition of an externally developed clinical-stage asset with strong proof-of-concept data represents the most efficient path to rebuilding the company's oncology pipeline and sustaining its competitive position in the immuno-oncology therapeutic area. The VRD-4187 candidate and the underlying VeriTCE platform technology are viewed as highly complementary to Penterra's existing commercial capabilities in oncology and its established relationships with key oncology investigators and treatment centers.

2.6 Board Authorization

On February 12, 2024, the Board of Directors of Penterra Pharmaceuticals Corp. authorized the exploration and pursuit of the proposed acquisition of Veridian Biosciences, Inc., including the engagement of outside legal counsel and financial advisors to conduct due diligence, negotiate the terms of a potential transaction, and take all actions reasonably necessary to advance the proposed acquisition. A copy of the relevant board resolution is maintained in the client file.

Advising on any other regulatory approvals or notifications that may be required under applicable federal, state, or foreign law.

9. Anticipated Timeline and Key Milestones

The following is a preliminary timeline for the proposed transaction, based on current expectations and subject to change as negotiations progress:

This timeline is preliminary and aspirational. The actual sequence and timing of events will depend on a number of factors, including the pace and results of due diligence, the status and progress of negotiations with the Sellers and their advisors, the timing and outcome of regulatory filings and reviews, and the availability and terms of acquisition financing. The engagement team will provide periodic updates to the client and to the firm's management as the transaction progresses.

10. Special Considerations / Key Issues Flagged

The following special considerations and key issues have been identified in connection with the proposed transaction and are flagged for the attention of the New Matters Committee:

10.1 Clinical-Stage Target with No Product Revenue

Veridian Biosciences, Inc. is a clinical-stage biotechnology company with no product revenue. The entire valuation of the Target is predicated on the clinical and commercial potential of its lead product candidate, VRD-4187, and the underlying VeriTCE platform technology. This presents heightened transaction risk relative to acquisitions of revenue-generating targets. The negotiation of the material adverse effect ("MAE") definition and the related closing conditions in the Stock Purchase Agreement will be a critical area of focus. In particular, the MAE definition and any carve-outs thereto must be carefully structured to address the inherent risks associated with a clinical-stage asset, including the risk of adverse clinical trial outcomes, unexpected safety signals, changes in the competitive landscape, and adverse FDA regulatory actions (including clinical holds, requests for additional studies, or refusals to file) occurring between signing and closing. The engagement team will work closely with Penterra's management, financial advisors, and scientific consultants to ensure that the contractual protections appropriately reflect the risk profile of the transaction.

10.2 Section 382 NOL Limitations

Veridian has accumulated significant net operating loss ("NOL") carryforwards, estimated at approximately $312 million as of December 31, 2023. These NOLs represent a potentially valuable tax asset for Penterra post-acquisition, to the extent they can be utilized to offset future taxable income. However, the utilization of Veridian's NOLs is subject to limitation under Internal Revenue Code Section 382, which imposes an annual limitation on the use of NOL carryforwards following an "ownership change" (generally defined as a greater than 50-percentage-point increase in stock ownership by one or more five-percent shareholders over a rolling three-year period). Given the multiple rounds of venture and growth equity financing completed by Veridian (Series A through Series D), particularly the Series C round completed in the third quarter of 2020, it is possible that one or more prior ownership changes have already occurred, which would have resulted in pre-existing Section 382 limitations on a portion of Veridian's NOLs. Due diligence will need to include a thorough Section 382 study analyzing all historical changes in Veridian's equity ownership and determining whether any prior ownership changes have occurred and, if so, the applicable annual limitation amounts. Leonard Cross (Tax Partner) will lead this workstream and advise on the implications for the overall transaction value and structure.

10.3 Transaction Structure and Tax Considerations

The transaction is currently anticipated to be structured as an all-cash stock purchase. No election under Section 338(h)(10) of the Internal Revenue Code is currently contemplated. A Section 338(h)(10) election, which would treat the stock purchase as an asset purchase for federal income tax purposes, would ordinarily be considered in the context of an acquisition of a C corporation in order to achieve a stepped-up tax basis in the Target's assets. However, given Veridian's significant NOL profile, a Section 338(h)(10) election could potentially trigger a substantial deemed gain at the Target level, consuming a meaningful portion of the NOLs without a corresponding tax benefit and potentially resulting in adverse tax consequences for the Sellers. Leonard Cross will advise on the optimal tax structuring of the transaction, including the analysis of Section 338(h)(10), Section 336(e), and any alternative structures that may be beneficial from a tax perspective.

10.4 Acquisition Financing

Penterra had approximately $2.1 billion in cash and cash equivalents on hand as of its most recently reported fiscal quarter. While Penterra has sufficient balance sheet liquidity to fund a significant portion of the anticipated purchase price from existing cash resources, it is expected that Penterra will seek partial acquisition financing in the form of a committed term loan facility to fund a portion of the purchase price and preserve financial flexibility. Preliminary discussions are underway with Summit Ridge Capital Partners, LP, as described in Section 8.8 above. The engagement team will review and advise on the terms of any commitment letter and credit agreement to ensure consistency with the definitive acquisition agreement, including any financing conditions, "SunGard" conditionality provisions, and cooperation covenants.

10.5 No-Shop Provision

The Stock Purchase Agreement is anticipated to include a no-shop covenant restricting Veridian and the Sellers from soliciting, initiating, encouraging, or entering into discussions or negotiations with third parties regarding alternative acquisition proposals during the period between signing and closing. The no-shop covenant is expected to include a limited fiduciary-out permitting the Veridian board of directors to consider and respond to unsolicited superior proposals, subject to customary procedural requirements (including notice and matching rights in favor of Penterra) and the payment of a termination fee in the event that the Veridian board elects to terminate the agreement to accept a superior proposal. The terms of the no-shop covenant, the fiduciary-out exceptions, and the termination fee will be key points of negotiation.

10.6 Indemnification and Representation and Warranty Insurance

The transaction is expected to include a contractual indemnification framework pursuant to which the Sellers will provide customary indemnification to Penterra for breaches of representations and warranties, breaches of covenants, and certain specified liabilities. In addition, it is anticipated that Penterra will procure a buyer-side representation and warranty ("R&W") insurance policy to supplement the contractual indemnification from the Sellers. R&W insurance is commonly utilized in private target acquisitions to bridge the gap between the buyer's indemnification requirements and the sellers' willingness to accept post-closing indemnification exposure, and its use is expected to facilitate negotiations regarding indemnification caps, baskets, survival periods, and other limitations. As noted in Section 8.4 above, Prescott Whitfield Insurance Brokers, Inc. is anticipated to be engaged to broker the R&W insurance placement.

10.7 Regulatory Considerations

The proposed transaction will require a pre-merger notification filing under the HSR Act, given that the anticipated purchase price exceeds the applicable notification thresholds. Stonebridge HSW Antitrust Advisors LLP has been engaged to advise on the HSR filing and antitrust clearance strategy. Based on a preliminary assessment of the parties' respective product portfolios and market positions, the transaction is not expected to raise significant antitrust concerns; however, a definitive antitrust risk assessment will be conducted following the completion of due diligence.

In addition, the FDA regulatory status of VRD-4187 will be closely monitored during the interim period between signing and closing. Veridian's Investigational New Drug application (IND 154832) and the ongoing Phase II clinical trial (ClinicalTrials.gov Identifier: NCT05837291) are subject to ongoing FDA oversight, and any adverse regulatory action by the FDA (including, but not limited to, a clinical hold, a refusal to file, or a request for additional clinical data) during the interim period could have a material impact on the value of the Target and the desirability of consummating the transaction. The Stock Purchase Agreement will need to include appropriate interim operating covenants and closing conditions to address these risks.

11. Document Retention and Filing

All documents, correspondence, memoranda, notes, emails, and other materials generated or received in connection with this matter shall be filed under Matter No. 1018-00008 in accordance with the firm's document retention and records management policies.

All electronic files related to this matter shall be maintained on the firm's secure document management system ("DMS") and shall be subject to the firm's information security policies and access controls. Access to the matter files shall be restricted to members of the engagement team and such other firm personnel as may be authorized by the Responsible Partner or the Office of the General Counsel.

Physical documents, to the extent any are generated or received, shall be stored in the firm's secure records storage facilities and catalogued in accordance with the firm's records management procedures.

The engagement team is reminded that all documents and communications related to this matter may be subject to the attorney-client privilege and/or the work product doctrine, and that appropriate steps should be taken to preserve and protect these privileges at all times.
