Business Combination Agreement

General Description of the Business Combination Agreement

On June 10, 2026, Copley Acquisition Corp, a Cayman Islands exempted company (“Copley” or “SPAC”), entered into a Business Combination Agreement (the “Business Combination Agreement”) with Ignite Proteomics, LLC, a Delaware limited liability company “Ignite” or the “Company”), Ignite Proteomics Holdings, Inc., a Delaware corporation (“Pubco”), Ignite Merger Sub I Inc., a Delaware corporation and a wholly-owned subsidiary of Pubco (“SPAC Merger Sub”), and Ignite Merger Sub II LLC, a Delaware limited liability company and a wholly-owned subsidiary of Pubco (“Company Merger Sub” and together with SPAC Merger Sub, the “Merger Subs”, and the Merger Subs collectively with Pubco and SPAC, the “SPAC Parties”), Jeffrey M. Busch, solely in his capacity as the Seller Representative, and Chibo Tang, solely in his capacity as the SPAC Representative. Terms used but not defined herein shall have the meanings defined in the Business Combination Agreement.

Pursuant to the Business Combination Agreement and subject to the terms and conditions set forth therein, (i) prior to the closing (the “Closing”, and the date and time of the Closing, the “Closing Date”) of the transactions contemplated by the Business Combination Agreement (the “Transactions”), SPAC shall transfer by way of continuation out of the Cayman Islands and into the State of Delaware, so as to re-domicile as and become a Delaware corporation pursuant to the Cayman Islands Companies Act (as revised) and the applicable provisions of the Delaware General Corporation Law (the “Conversion”), (ii) following the Conversion and on the Closing Date, (A) SPAC Merger Sub will merge with and into Copley, with Copley continuing as the surviving entity (the “SPAC Merger”) and, as a result of which, each issued and outstanding security of Copley immediately prior to the effective time of the SPAC Merger shall no longer be outstanding and shall automatically be cancelled in exchange for which the security holders of Copley shall receive substantially equivalent securities of Pubco, and (B) Company Merger Sub will merge with and into Ignite, with Ignite continuing as the surviving entity (the “Company Merger,” and together with the SPAC Merger, the “Mergers”), and as a result of which each issued and outstanding membership interest of Ignite immediately prior to the effective time of the Company Merger shall no longer be outstanding and shall automatically be cancelled in exchange for which the holders of such membership interests shall receive shares of common stock, par value $0.0001 per share, of Pubco (“Pubco Common Stock”). As a result of the Mergers and the other Transactions, Copley and Ignite will become wholly-owned subsidiaries of Pubco, all upon the terms and subject to the conditions set forth in the Business Combination Agreement, and Pubco will become a publicly traded company.

At the effective time of the Mergers (the “Effective Time”), by virtue of the SPAC Merger and following the Conversion, each issued and outstanding share of SPAC common stock (other than treasury shares) shall be converted automatically into the right to receive one share of Pubco Common Stock, each issued and outstanding SPAC Public Warrant shall be converted into one Pubco Public Warrant and each issued and outstanding SPAC Private Warrant shall be converted into one Pubco Private Warrant, in each case having substantially the same terms and conditions as the applicable SPAC warrant, except that such warrants shall represent the right to acquire shares of Pubco Common Stock in lieu of shares of SPAC common stock.

Additionally, at the Effective Time, by virtue of the Company Merger, each membership interest of Ignite issued and outstanding immediately prior to the Effective Time (other than any excluded interests) will be cancelled and cease to exist in exchange for the right to receive shares of Pubco Common Stock comprising the Merger Consideration (as defined below). Any outstanding convertible securities of Ignite, if not exercised or converted prior to the Effective Time, shall be cancelled, retired and terminated and cease to represent a right to acquire membership interests of Ignite.

Consideration

The aggregate consideration to be paid to holders of Ignite’s membership interests as of the Effective Time (collectively, the “Sellers”) pursuant to the Company Merger shall consist of a number of newly issued shares of Pubco Common Stock equal to One Hundred and Fifty Million U.S. Dollars ($150,000,000) divided by Ten U.S. Dollars ($10.00) (the “Merger Consideration”). At the Effective Time, each Seller’s membership interests issued and outstanding as of immediately prior to the Effective Time shall be automatically cancelled and extinguished and converted into the right to receive such Seller’s percentage of the Merger Consideration in the form of Pubco Common Stock; provided, however, that Ignite may elect, in its sole discretion, prior to the Effective Time to receive in lieu of all or any number of shares of Pubco Common Stock issuable as Merger Consideration the same number of Pubco Common Stock Equivalents.

Additionally, at the Closing, Pubco shall pay to Copley Acquisition Sponsors Limited, a British Virgin Islands company limited by shares (the “Sponsor Payment Recipient”), in cash by wire transfer of immediately available funds, an amount equal to Four Million U.S. Dollars ($4,000,000). The Sponsor Payment Recipient is distinct from Copley Acquisition Sponsors, LLC, the “Sponsor” party to the Insider Letter Amendment described below.

Representations and Warranties

The Business Combination Agreement contains representations and warranties that are reasonably customary for similar transactions that are made by the parties as of the date of the Business Combination Agreement, or other specified dates, solely for the benefit of certain of the parties to the Business Combination Agreement, and in certain cases are subject to specified exceptions and materiality, Material Adverse Effect (as defined below), knowledge and other qualifications contained in the Business Combination Agreement or in information provided pursuant to certain disclosure schedules to the Business Combination Agreement. “Material Adverse Effect” means, with respect to any specified person or entity, any fact, event, occurrence, change or effect that has had or would reasonably be expected to have, individually or in the aggregate, a material adverse effect upon the business, assets, liabilities, results of operations, prospects or condition (financial or otherwise) of such person or entity and its subsidiaries, taken as a whole, or the ability of such person or entity or any of its subsidiaries on a timely basis to consummate the transactions contemplated by the Business Combination Agreement or the ancillary documents to which it is a party or bound or to perform its obligations thereunder, in each case subject to certain customary exceptions.

No Survival

The representations and warranties of the parties contained in the Business Combination Agreement terminate as of, and do not survive, the Closing, and there are no indemnification rights for another party’s breach. The covenants and agreements of the parties contained in the Business Combination Agreement do not survive the Closing, except those covenants and agreements to be performed after the Closing, which covenants and agreements will survive until fully performed.

Covenants of the Parties

Each party to the Business Combination Agreement has agreed to use its commercially reasonable efforts, and to cooperate fully with one another, to consummate the Transactions. The Business Combination Agreement also contains certain customary covenants by each of the parties that apply during the period between the signing of the Business Combination Agreement and the earlier of the Closing or the termination of the Business Combination Agreement (the “Interim Period”), including (i) the provision of access to the applicable party’s properties, books and personnel; (ii) the operation of the parties’ respective businesses in the ordinary course of business; (iii) the current and timely filing of Copley’s public filings; (iv) no insider trading; (v) notifications to the other parties of certain breaches, consent requirements and other matters; (vi) obtaining third party and regulatory approvals; (vii) tax matters; (viii) further assurances; (ix) public announcements; (x) confidentiality; and other covenants. The Business Combination Agreement also contains certain customary post-Closing covenants, including, without limitation, in regard to (1) tax matters; (2) the maintenance of books and records; (3) the indemnification of directors and officers; and (4) the use of proceeds from Copley’s trust account. Additionally:

Each of Copley and Ignite will not solicit or enter into a competing alternative transaction, in accordance with customary terms and provisions set forth in the Business Combination Agreement.

Copley will not approve, endorse or recommend, or publicly propose to approve, endorse or recommend, any Acquisition Proposal (as defined in the Business Combination Agreement), or otherwise change, withdraw, withhold, qualify or modify its recommendation to its shareholders for approval of the Business Combination Agreement and the Transactions (a “Change in Recommendation”); provided, however, that if at any time prior to (but not after) obtaining the approval of Copley’s shareholders, the Copley board of directors determines in good faith, in response to an Intervening Event (as defined in the Business Combination Agreement) after consultation with its outside legal counsel, that the failure to make a Change in Recommendation would be a breach of its fiduciary duties under applicable law, then the board may make a Change in Recommendation, provided that Copley delivers, pursuant to procedures set forth in the Business Combination Agreement, written notice advising Ignite that the Copley board of directors proposes to take such action and containing the material facts underlying the board’s determination. If requested by Ignite, Copley will use its reasonable best efforts to engage in good faith negotiations with Ignite to make adjustments in the terms and conditions of the Business Combination Agreement that obviate the need for a Change in Recommendation.

Ignite will deliver to Copley audited consolidated financial statements of Ignite certified as audited in accordance with GAAP and the standards of the PCAOB by a -PCAOB-qualified auditor, accompanied by an unqualified opinion of the auditor thereon (collectively, the “Audited Financials”), as soon as reasonably practicable after the date of the Business Combination Agreement but no later than ten (10) Business Days from the date of the Business Combination Agreement (the “Audit Delivery Date”). In addition, during the Interim Period, Ignite will deliver to Copley unaudited quarterly and annual financial information through the Closing Date.

Copley, Ignite and Pubco will, as promptly as practicable after the date of the Business Combination Agreement, prepare and file with the U.S. Securities and Exchange Commission (the “SEC”), a registration statement on Form S-4 (as amended, the “Registration Statement”) in connection with the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the securities of Pubco to be issued pursuant to the Transactions, and containing a proxy statement/prospectus for the solicitation of proxies from Copley shareholders to approve the Business Combination Agreement, the Transactions and related matters at an extraordinary general meeting of Copley’s shareholders, and providing Copley’s public shareholders with an opportunity to request redemption of their public shares in connection with the Transactions, as required by Copley’s amended and restated memorandum and articles of association and Copley’s initial public offering prospectus (the “Redemption”).

Promptly after the Registration Statement has become effective and been distributed by Pubco, Ignite will call a meeting of its members or obtain written consent in order to obtain the requisite vote of the holders of Ignite’s membership interests to approve the Business Combination Agreement and each of the ancillary documents to which Ignite is or is required to be a party or bound and the consummation of the transactions contemplated thereby (the “Required Company Member Approval”) and to take all other actions necessary or advisable to secure the Required Company Member Approval, including enforcing the Seller Support Agreements (as described below). At the request of Copley, Ignite shall make the members of its management reasonably available to participate in management presentations, “road shows,” rating agency presentations, meetings with financing sources and similar events in connection with obtaining the approval of Copley’s shareholders, any “share recycling” efforts by Copley and the obtaining of any debt or equity financing, ratings or governmental or other third-party approvals.

The parties shall take all action necessary so that, effective at the Closing, the post-Closing board of directors of Pubco will consist of seven (7) individuals, designated by Ignite, at least four (4) of whom shall be required to qualify as independent directors under the rules of the New York Stock Exchange LLC (the “NYSE”), and one (1) of whom shall be the chief executive officer of Ignite. The parties shall also take all action necessary so that the individuals serving as the chief executive officer and chief financial officer, respectively, of Pubco immediately after the Closing will be the same individuals (in the same office) as that of Ignite immediately prior to the Closing (unless, at its sole discretion, Ignite desires to appoint another qualified person to either such role, in which case, such other person(s) identified by Ignite shall serve in such role or roles).

During the Interim Period, (i) Copley shall use its best efforts to obtain up to Twenty Million U.S. Dollars ($20,000,000) in Transaction Financing, and (ii) Ignite shall use its best efforts to obtain up to Ten Million U.S. Dollars ($10,000,000) in Transaction Financing. “Transaction Financing” means a capital raising transaction in connection with the Transactions structured as one or a combination of common equity, preferred equity, convertible equity or debt, non-redemption or backstop arrangements with respect to the trust account, a committed equity facility, debt facility, and/or other sources of cash or cash equivalents, in each case, whether such investment is into Copley, Ignite or Pubco.

The parties agree that, after taking into account any payments made in connection with the Redemption, funds in Copley’s trust account and any proceeds from any Transaction Financing will be used first to pay Copley’s accrued and unpaid expenses, Copley’s deferred expenses, including deferred initial public offering expenses and legal fees, loans owed by Copley to the Sponsor for expenses, administrative costs and Extension Expenses, and any other unpaid expenses of Ignite as of the Closing, with any remaining cash to be used for working capital and general corporate purposes of Pubco and the surviving subsidiaries.

Conditions to Closing

The obligations of the parties to consummate the Transactions are subject to various conditions, including the following mutual conditions of the parties, unless waived: (i) the approval of the Business Combination Agreement and the Transactions and related matters by the requisite vote of each of Copley’s shareholders and Ignite’s members; (ii) the expiration or termination of any waiting period applicable to the consummation of the Business Combination Agreement under any antitrust laws; (iii) obtaining material regulatory approvals; (iv) obtaining or making the Consents required to be obtained from or made with third Persons; (v) no law or order preventing or prohibiting the Transactions; (vi) appointment of the Post-Closing Pubco Board consistent with the requirements of the Business Combination Agreement; (vii) the effectiveness of the Registration Statement; (viii) the Conversion shall have been consummated; (ix) Pubco shall have amended and restated its certificate of incorporation in a form satisfactory to Copley and Ignite; (x) shares of Pubco Common Stock and Pubco Public Warrants shall have been approved for listing on the NYSE upon the Closing; and (xi) Pubco shall have adopted, on or prior to the Closing, an equity incentive plan in a form satisfactory to Copley and Ignite, and which will provide for awards for a number of shares of Pubco Common Stock equal to fifteen percent (15%) of the aggregate number of shares of Pubco Common Stock issued and outstanding immediately after the Closing.

In addition, unless waived by Ignite, the obligations of Ignite to consummate the Transactions are subject to the satisfaction of the following closing conditions, in addition to customary certificates and other closing deliveries: (i) the representations of Copley relating to organization and standing, authorization, non-contravention, capitalization (other than the first sentence of such representation in the Business Combination Agreement) and finders and brokers being true and correct in all material respects on and as of the date of the Business Combination Agreement and as of the Closing Date; (ii) the representations and warranties of Copley set forth in the first sentence of the capitalization representation being true and correct in all respects (except for de minimis inaccuracies) on and as of the date of the Business Combination Agreement and as of the Closing Date; (iii) all other representations and warranties of Copley being true and correct (without giving effect to any limitations as to “materiality” or any similar limitation set forth herein) in all respects on and as of the date of the Business Combination Agreement and as of the Closing Date, as though made on and as of the Closing Date, except where the failure of such representations and warranties to be true and correct, individually and in the aggregate has not had a Material Adverse Effect on Copley; (iv) the SPAC Parties having performed in all material respects their obligations and complied in all material respects with the covenants and agreements under the Business Combination Agreement required to be performed or complied with by them on or prior to the Closing Date; (v) the Insider Letter Amendment (as defined below), the Amended Registration Rights Agreement and the Sponsor Letter being in full force and effect as of the Closing; and (vi) the sum of (A) the aggregate cash proceeds available for release from the trust account (after giving effect to the completion and payment of the Redemption), plus (B) the net proceeds of any Transaction Financings conducted by Copley, shall equal or exceed Fifteen Million U.S. Dollars ($15,000,000) (the “SPAC Minimum Cash Condition”).

Unless waived by Copley, the obligations of Copley to consummate the Transactions are subject to the satisfaction of the following closing conditions, in addition to customary certificates and other closing deliveries: (i) the representations of Ignite relating to organization and standing, authorization, non-contravention, capitalization (other than the first sentence of such representation in the Business Combination Agreement) and finders and brokers being true and correct (without giving effect to any limitation as to “materiality” set forth therein) in all material respects on and as of the date of the Business Combination Agreement and as of the Closing Date; (ii) the representations and warranties set forth in the first sentence of the capitalization representation being true and correct in all respects on and as of the date of the Business Combination Agreement and as of the Closing Date; (iii) all other representations and warranties of Ignite being true and correct (without giving effect to any limitation as to “materiality” or “Material Adverse Effect” or any similar limitation set forth herein) in all respects on and as of the date of the Business Combination Agreement and on and as of the Closing Date, except where the failure of such representations and warranties to be true and correct, individually and in the aggregate has not had a Material Adverse Effect; (iv) Ignite having performed in all material respects all of its obligations and complied in all material respects with all of its agreements and covenants under the Business Combination Agreement required to be performed or complied with on or prior the Closing Date; (v) absence of any Material Adverse Effect with respect to the Target Companies since the date of the Business Combination Agreement; (vi) each Non-Competition Agreement, each Lock-Up Agreement, the Insider Letter Amendment, the Seller Support Agreement and the Amended Registration Rights Agreement being in full force and effect as of the Closing; (vii) Copley and Pubco having received employment agreements, in each case effective as of the Closing, in form and substance acceptable to Copley, between certain employees and Pubco or a subsidiary, and each such employment agreement duly executed by the parties thereto; and (viii) the sum of net proceeds of any Transaction Financings conducted by Ignite shall equal or exceed Seven Million Five Hundred Thousand U.S. Dollars ($7,500,000) (the “Company Minimum Cash Condition”).

The Business Combination Agreement may also be terminated under certain other customary and limited circumstances at any time prior to the Closing, including, among other reasons: (i) by mutual written consent of Copley and Ignite; (ii) by written notice by either Copley or Ignite to the other if a governmental authority of competent jurisdiction shall have issued an order or taken any other action permanently restraining, enjoining or otherwise prohibiting the Transactions, and such order or other action has become final and non-appealable; (iii) by Ignite for Copley’s uncured material breach of the Business Combination Agreement, such that the related closing condition would not be met; (iv) by Copley for Ignite’s uncured material breach of the Business Combination Agreement, such that the related closing condition would not be met; (v) by Copley, if there shall have been a Material Adverse Effect on Ignite and its subsidiaries following the date of the Business Combination Agreement which is uncured and continuing; (vi) by written notice by either Copley or Ignite, if Copley holds its extraordinary general meeting to approve the Business Combination Agreement and the Transactions, and such approval is not obtained; and (vii) by written notice from Copley to Ignite if Ignite has not delivered the Audited Financials on or before the Audit Delivery Date.

Simultaneously with the execution of the Business Combination Agreement, holders of membership interests of Ignite holding interests sufficient to approve the adoption of the Business Combination Agreement and approve the Company Merger and the other transactions contemplated by the Business Combination Agreement (the “Holders”) entered into support agreements (each, a “Seller Support Agreement”), pursuant to which, among other things, each Holder agreed to vote its membership interests of Ignite (the “Membership Interests”) in favor of the adoption of the Business Combination Agreement, the ancillary documents, the approval of the Transactions and any amendments to Ignite’s organizational documents in connection therewith and against any competing acquisition proposal or alternative transaction. Each Holder also granted an irrevocable proxy to Copley with respect to voting on matters related to approval of the Business Combination Agreement and Transactions.

A copy of the form of the Seller Support Agreement is attached as Exhibit 10.1 hereto and is incorporated herein by reference.

Insider Letter Amendment

Simultaneously with the execution of the Business Combination Agreement, Copley, Pubco, Ignite, Copley Acquisition Sponsors, LLC (the “Sponsor”) and Copley’s directors and officers entered into an amendment (the “Insider Letter Amendment”) to the letter agreement that was entered into in connection with Copley’s initial public offering (the “Insider Letter”) to (i) add Pubco and Ignite as parties to the Insider Letter, (ii) revise the terms of the Insider Letter to reflect the Transactions, including the issuance of Pubco securities in exchange for Copley securities, and have Pubco assume and be assigned the rights and obligations of Copley under the Insider Letter, and (iii) amend the terms of the lock-up such that the Founder Shares lock-up period will expire upon the earlier of (A) 90 days following the consummation of the Business Combination or (B) the date on which Pubco completes a liquidation, merger, share exchanges, reorganization or other similar transaction that results in all of Pubco’s shareholders having the right to exchange their shares for cash, securities or other property, subject to and contingent upon the Closing. A copy of the Insider Letter Amendment is attached as Exhibit 10.2 hereto and is incorporated herein by reference.

Non-Competition and Non-Solicitation Agreement

At or prior to the Effective Date (as defined in the Business Combination Agreement), Copley, Pubco and Ignite are expected to enter into a Non-Competition and Non-Solicitation Agreement in favor of Pubco and Ignite with Jeffrey M. Busch, effective as of the Closing, which will provide for a restricted period from the Closing until the third anniversary of the Closing Date. The Non-Competition and Non-Solicitation Agreement is also a condition to Copley’s obligations to consummate the Transactions.

Lock-Up Agreements

At or prior to the Effective Date (as defined in the Business Combination Agreement), the Sellers and the directors and officers of Ignite are expected to enter into Lock-Up Agreements in form and substance reasonably satisfactory to Copley and Ignite, each to be effective as of the Closing for 90 days following the consummation of the Business Combination.

Side Letter and Guaranty Agreement

Simultaneously with the execution of the Business Combination Agreement, Aditxt Inc., a Delaware corporation and direct parent of Ignite (the “Guarantor”), and Copley entered into a Side Letter and Guaranty Agreement (the “Guaranty”), pursuant to which the Guarantor absolutely, unconditionally and irrevocably guarantees to Copley, as primary obligor and not merely as surety, the full, complete and punctual payment, performance and discharge of each obligation of Ignite arising under or in connection with the Business Combination Agreement and the ancillary documents to which Ignite is a party, including specified expenses, indebtedness-related obligations, covenants and other monetary and performance obligations. The Guaranty is in addition to, and does not limit, modify or supersede, any obligation of Ignite under the Business Combination Agreement. A copy of the Guaranty is attached as Exhibit 10.3 hereto and is incorporated herein by reference.

The Business Combination Agreement and other agreements described above have been included to provide investors with information regarding their respective terms. They are not intended to provide any other factual information about Copley, Ignite, or the other parties thereto. In particular, the assertions embodied in the representations and warranties in the Business Combination Agreement were made as of a specified date, are modified or qualified by information in one or more confidential disclosure schedules prepared in connection with the execution and delivery of the Business Combination Agreement, may be subject to a contractual standard of materiality different from what might be viewed as material to investors, or may have been used for the purpose of allocating risk between the parties. Accordingly, the representations and warranties in the Business Combination Agreement are not necessarily characterizations of the actual state of facts about Copley, Ignite or the other parties thereto at the time they were made or otherwise and should only be read in conjunction with the other information that Copley makes publicly available in reports, statements and other documents filed with the SEC. Copley and Ignite investors and securityholders are not third-party beneficiaries under the Business Combination Agreement and should not rely on the representations, warranties, covenants and agreements, or any descriptions thereof, as characterizations of the actual state of facts or condition of any party to the Business Combination Agreement.
