(ii) Except as otherwise specified in this Agreement, if a replacement director (a “Replacement Director”) is appointed to the Board pursuant to this Section 1(f), all reference in this Agreement to the term “New Director” will include such Replacement Director, as applicable.

If the Nominating Committee does not accept a substitute person recommended by the Constellation Parties as a Replacement Director, then the Constellation Parties will have the right to recommend additional substitute person(s) whose appointment will be subject to the Nominating Committee recommending such person in accordance with the procedures described in this Section 1(f). Upon the recommendation of a candidate for Replacement Director by the Nominating Committee, the Board shall review and vote on the appointment of such candidate to the Board no later than five Business Days after the Nominating Committee’s recommendation of such candidate; provided, that if the Board does not approve and appoint such candidate for Replacement Director to the Board (such approval not to be unreasonably withheld), the Parties shall continue to follow the procedures described in this Section 1(f)(iv) until a Replacement Director is approved and appointed to the Board.

3. Information Sharing with Approved Constellation Persons.

(a) Non-Disclosure. Except as set forth in Section 3(b), the New Director hereby agrees that all Confidential Information shall not be disclosed to any Third Party and shall not be used for any purpose other than in connection with (i) the New Director’s duties as a director of the Company and (ii) evaluating or monitoring the Constellation Parties’ investment in the Company.

(b) Permitted Disclosures.

(i) Notwithstanding the foregoing and subject to Section 3(d), the New Director may, if such person wishes to do so, provide Confidential Information to Approved Constellation Persons; provided, however, that the Constellation Parties shall (A) inform each Approved Constellation Person of the confidential nature of the Confidential Information and (B) cause each Approved Constellation Person not to disclose any Confidential Information to any Person other than to Approved Constellation Persons in accordance with this Section 3 and not to use any Confidential Information other than in connection with (x) the New Director’s duties as a director of the Company and (y) evaluating or monitoring the Constellation Parties’ investment in the Company. The Constellation Parties shall be jointly and severally responsible for any breach of this Section 3 by an Approved Constellation Person or any other Person who receives Confidential Information from the New Director hereunder.

(ii) If the Constellation Parties or any Approved Constellation Person is (A) legally compelled, by deposition, interrogatory, request for documents, subpoena, civil investigation, demand, order or similar process, to disclose any Confidential Information or (B) determines (on the advice of legal counsel) that it is required by law or regulation to disclose any Confidential Information, prior to making such disclosure, the Constellation Parties must, to the extent practicable and legally permissible, (x) promptly notify the Company of the circumstances surrounding such requirement or request and (y) reasonably cooperate with the Company, at the Company’s sole expense, in any reasonable attempt it may make to obtain a protective order, other appropriate remedy, or an appropriate assurance that confidential treatment will be afforded to its Confidential Information. If a protective order or other appropriate remedy or assurance is not obtained, the Constellation Parties agree to only disclose (or cause to be disclosed, as applicable) that portion of the Confidential Information that is legally required to be disclosed (on the advice of legal counsel). Notwithstanding anything to the contrary in this Agreement, Confidential Information may be disclosed in response to a routine audit, examination or request from a regulatory or self-regulatory authority or bank examiner, without providing notice or otherwise having to comply with any of the foregoing provisions of this Section 3(b)(ii), so long as such audit, examination or request is not directed at the Company or the Confidential Information. For the purposes of this Agreement, the Constellation Parties agree that none of them shall be deemed to be legally required to disclose any Confidential Information solely by virtue of

the fact that, absent such disclosure, the Constellation Parties, any of their respective Affiliates or any Group of which any Constellation Party is a member (1) would be prohibited from purchasing, selling or engaging in derivative or other voluntary transactions with respect to the securities of the Company or any Debt Instruments of the Company or (2) would be unable to file any proxy materials or tender or exchange offer materials in compliance with Section 14 of the Exchange Act or the rules promulgated thereunder. Neither the Constellation Parties nor any of their respective Affiliates or any Group of which any Constellation Party is a member will file any Schedule 13D or other filing pursuant to applicable securities laws, or otherwise make any public statement, disclosing any of the Confidential Information.

(iii) Each Constellation Party hereby acknowledges that it is aware, and shall advise each of the Approved Constellation Persons who receive Confidential Information pursuant to this Section 3(b), that (A) the Confidential Information being furnished to the Approved Constellation Persons may contain material, non-public information concerning the Company and (B) the United States securities laws, including Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder prohibit any Person that has received from an issuer material, non-public information from purchasing or selling securities of such issuer or from communicating such information to any other Person under circumstances in which it is reasonably foreseeable that such Person is likely to purchase or sell such securities. During the Specified Period, the Company shall provide the Constellation Parties with at least two Business Days’ advance written notice of each opening and expiration of each blackout period, and the Constellation Parties shall not purchase or sell, directly or indirectly, any securities of the Company during any blackout periods applicable to all directors under the Company’s ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ policy, as amended from time to time.

(c) Return/Destruction. Following the expiration of the Specified Period, upon written request of the Company, the Constellation Parties agree to (and agree to cause the Approved Constellation Persons to, if applicable) (i) promptly (and in any event within ten Business Days of such expiration) return or destroy, in the Company’s sole discretion (and upon request by the Company, confirm in writing such return or destruction to the Company) all Confidential Information of the Company and its Affiliates in their possession (including, for the avoidance of doubt, that portion of any documents, materials and other items that contain Confidential Information), (ii) not to retain any copies, extracts or other reproductions in whole or in part, mechanical or electronic, of such written material, and (iii) to destroy all computer records, documents, memoranda, notes and other writings prepared by the New Director or an Approved Constellation Person that contain the Confidential Information of the Company or any of its Affiliates; provided, however, that Constellation Software and the Approved Constellation Persons shall be entitled to retain copies of all such Confidential Information in restricted access legal files or pursuant to automatic electronic archiving and back-up procedures or pursuant to Constellation Software’s document retention policies; provided, that the Constellation Parties and the Approved Constellation Persons shall be subject to the confidentiality obligations of this Section 3 with respect to such retained Confidential Information for the period set forth in Section 3(f).

(d) Potential Conflicts of Interest.

(i) It is understood and agreed that the Company may, in its sole discretion, from time to time, on the advice of legal counsel, determine that disclosure of certain of its competitively sensitive Confidential Information by the New Director to Constellation Software or the Approved Constellation Persons can reasonably be expected to have adverse consequences to its business or under applicable law. In each such case, the Company may cause, in its sole discretion, (A) such competitively sensitive Confidential Information to be made available by the New Director to Constellation Software or the Approved Constellation Persons only in accordance with additional procedures mutually agreed by the New Director, and the Company in writing to permit disclosure of such competitively sensitive Confidential Information in an appropriate manner, or (B) the New Director to withhold sharing such competitively sensitive Confidential Information with Constellation Software or the Approved Constellation Persons, and the New Director shall not share such competitively sensitive Confidential Information with Constellation Software or such Approved Constellation Persons. Notwithstanding anything in this Agreement to the contrary, the New Director shall not utilize the Company’s competitively sensitive Confidential Information in providing guidance to or acting on behalf of Constellation Software, its Affiliates or the Approved Constellation Persons in a manner that is detrimental to the Company. For purposes of this Section 3(d), “competitively sensitive Confidential Information” shall mean any non-public information the disclosure of which would reasonably be expected to (x) lessen competition or (y) violate applicable competition/anti-trust laws, including information concerning or reflecting (1) the Company’s current or future prices, pricing plans or pricing strategies (including per-product margins, discounts, rebates and other price terms) of the Company’s products and services or future product plans, (2) detailed sales by customer or customer contract terms, (3) detailed purchases by vendor or vendor contract terms, (4) detailed individual employee compensation and benefits, (5) material non-public information on trademarks, patents, trade secrets, and research and development, (6) the Company’s strategy or business plans to compete with any Scheduled Entity, or (7) the Company’s strategy or potential strategy with respect to any contemplated transaction, collaboration or investment involving any Scheduled Entity.

(ii) The Constellation Parties agree that the Board or any committee thereof, for the purposes of fulfilling the discharge of its fiduciary duties upon the advice of its legal counsel, may, upon the advice of its legal counsel, in its sole discretion, recuse the New Director from any Board or committee meeting (or applicable portion thereof) at which the Board or any such committee is evaluating and/or taking action with respect to (A) the exercise of any of the Company’s rights or enforcement of any of the obligations under this Agreement, (B) any transaction or investment with, by or proposed by (i) the Constellation Parties, their Affiliates or Associates involving the Company or (ii) any Scheduled Entity, or (C) any other business activities, in each case, that the Company determines upon the advice of its legal counsel, would create a conflict of interest for the New Director. The Board or such committee, as applicable, may withhold from the New Director any material distributed to the directors solely to the extent it directly relates to the subject matter giving rise to that recusal under clauses (A), (B) or (C) above.

(iii) Constellation Software shall provide the Company with written notice within five Business Days of the date on which any Constellation Party or any Affiliate thereof enters into a Competitive Transaction. The Company agrees that is shall, and shall cause its Representatives to, keep such information strictly confidential unless and until such time as it is publicly disclosed by any Constellation Party or Affiliate thereof.

(e) Privileged Information. Notwithstanding anything to the contrary contained in this Agreement, the Company shall be permitted to cause the New Director to withhold sharing any Confidential Information with Constellation Software or the Approved Constellation Persons, and the New Director shall not share such Confidential Information, as is reasonably determined by the Company upon the advice of legal counsel to be necessary to protect the Company’s attorney-client or other legal and professional privileges.

(f) Survival. Subject to Section 3(c), the confidentiality, use and other obligations under this Section 3 shall terminate 18 months after the expiration of the Specified Period; provided, that Constellation Software shall, and shall cause any Approved Constellation Persons in possession of Confidential Information to, maintain in accordance with the confidentiality obligations set forth herein any Confidential Information constituting trade secrets for such longer time as such information constitutes a “trade secret” of the Company or any of its subsidiaries, joint ventures or other Affiliates, as defined under 18 U.S.C. § 1839(3); provided, that the Company shall identify any such information that constitutes a “trade secret” as defined under 18 U.S.C. § 1839(3) when sharing such information with the New Director.

4. Public Announcement. Not later than 10:00 p.m. Eastern Time on March 5, 2026, the Company shall issue a press release in the form attached to this Agreement as Exhibit A (the “Press Release”). The Company shall file with the SEC a Current Report on Form 8-K disclosing its entry into this Agreement and including a copy of this Agreement and the Press Release as exhibits thereto. The Company shall provide the Constellation Parties and their counsel with a copy of such Form 8-K prior to its filing with the SEC and shall consider any timely comments of the Constellation Parties and their Representatives. The Company acknowledges and agrees that the Constellation Parties may file this Agreement as an exhibit to a Schedule 13D or any amendment thereto, as applicable, disclosing their entry into this Agreement and including a copy of this Agreement and the Press Release as exhibits thereto (such Schedule 13D or amendment thereto disclosing the entry into this Agreement, the “Constellation 13D”). The Company shall be given a reasonable opportunity to review and comment on the Constellation 13D during the Specified Period, and the Constellation Parties shall consider any timely comments of the Company and their Representatives. Neither of the Company or any of its Affiliates nor the Constellation Parties or any of their Affiliates shall make any public statement regarding the subject matter of this Agreement, this Agreement or the matters set forth in the Press Release prior to the issuance of the Press Release without the prior written consent of the other party.

8. Specific Performance; Remedies; Venue; Waiver of Jury Trial.

(a) The Company and the Constellation Parties acknowledge and agree that irreparable injury to the other party hereto would occur in the event any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that such injury would not be adequately compensable by the remedies available at law (including the payment of money damages). It is accordingly agreed that the Company and the Constellation Parties will be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to seek to enforce specifically the terms and provisions of this Agreement, in addition to any other remedy to which they are entitled at law or in equity. Furthermore, the Company and each Constellation Party agrees: (1) the non-breaching party will be entitled to injunctive and other equitable relief to prevent any such breach, without proof of actual damages; and (2) the breaching party will not plead in defense thereto that there would be an adequate remedy at law.

(b) This Agreement, and all disputes, claims, actions, suits or proceedings based upon, arising out of or related to this Agreement or the transactions contemplated hereby, shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflicts of law rules or principles that would result in the application of the law of any other state or jurisdiction.

(c) In the event any dispute arises out of or relates to this Agreement or the transactions contemplated hereby, the Company and each Constellation Party (i) irrevocably and unconditionally submits to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (the “Chancery Court”) (or, only if the Chancery Court declines to accept jurisdiction over a particular matter, the other state or federal courts located in the State of Delaware), (ii) agrees that it will not attempt to deny or defeat such jurisdiction by motion or other request for leave from any such courts, (iii) agrees that any actions or proceedings arising in connection with this Agreement or the transactions contemplated by this Agreement shall be brought, tried, and determined only in such courts, (iv) waives any claim of improper venue or any claim that those courts are an inconvenient forum and (v) agrees that it will not bring any action relating to this Agreement or the transactions contemplated hereunder in any court other than the aforesaid courts. The parties to this Agreement agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 7 or in such other manner as may be permitted by applicable law as sufficient service of process, shall be valid and sufficient service thereof.

(d) EACH OF THE PARTIES, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH COUNSEL, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY RELATED INSTRUMENT OR AGREEMENT, OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREBY, OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTIONS OF ANY OF THEM. NO PARTY HERETO SHALL SEEK TO CONSOLIDATE, BY COUNTERCLAIM OR OTHERWISE, ANY ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED.

9. Affiliate Breaches. Each of the Constellation Parties agrees to cause its and their Affiliates and Representatives to comply with the terms of this Agreement applicable to such Affiliates and Representatives, respectively, and shall be responsible for any breach of the terms of this Agreement applicable to such Affiliates or Representatives, respectively. A breach of the terms of this Agreement applicable to an Affiliate or Representative of any Constellation Party, if such Affiliate or Representative is not a party hereto, shall be deemed to occur if such Affiliate or Representative engages in conduct that would constitute a breach of the terms of this Agreement applicable to such Affiliate or Representative, respectively, if such Affiliate or Representative were a party hereto.

10. Severability. If at any time subsequent to the Effective Date, any provision of this Agreement is held by any court of competent jurisdiction to be illegal, void or unenforceable, such provision will be of no force and effect, but the illegality or unenforceability of such provision will have no effect upon the legality or enforceability of any other provision of this Agreement.

11. Termination. This Agreement will terminate upon the expiration of the Specified Period. Upon such termination, this Agreement shall have no further force and effect. Notwithstanding the foregoing, Sections 3 and 7 to 18 shall survive termination of this Agreement, and no termination of this Agreement shall relieve any party of liability for any breach of this Agreement arising prior to such termination.

12. Expenses. All fees, costs and expenses incurred in connection with this Agreement and all matters related to this Agreement will be paid by the party incurring such fees, costs or expenses.

13. Counterparts. This Agreement may be executed in one or more counterparts, including via electronic signature (which shall, for the avoidance of doubt, include via DocuSign or similar platform), each of which will be deemed to be an original copy of this Agreement.

14. No Third-Party Beneficiaries; Successors and Assigns. This Agreement is solely for the benefit of the Company and the Constellation Parties and is not enforceable by any other Persons. No party to this Agreement may assign its rights or delegate its obligations under this Agreement without the prior written consent of the other parties. Subject to the foregoing, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by and against the permitted successors and assigns of each of the Company and the Constellation Parties.

15. No Waiver. No failure or delay by any party in exercising any right or remedy hereunder will operate as a waiver thereof, nor will any single or partial waiver thereof preclude any other or further exercise thereof or the exercise of any other right or remedy hereunder. The failure of a party to insist upon strict adherence to any term of this Agreement on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement.

16. Entire Understanding; Amendment. This Agreement contains the entire understanding of the parties with respect to the subject matter hereof and supersedes any and all prior and contemporaneous agreements, memoranda, arrangements and understandings, both written and oral, between the parties, or any of them, with respect to the subject matter of this Agreement. This Agreement may be amended only by an agreement in writing executed by the Company and the Constellation Parties.

17. Interpretation and Construction.

Each party and its counsel cooperated and participated in the drafting and preparation of this Agreement and the documents referred to herein, and all drafts relating thereto exchanged among the parties will be deemed the work product of all of the parties and may not be construed against any party by reason of its drafting or preparation. Accordingly, any rule of law or any legal decision that would require interpretation of any ambiguities in this Agreement against any party that drafted or prepared it is of no application and is hereby expressly waived by the Company and each Constellation Party, and any controversy over interpretations of this Agreement will be decided without regard to events of drafting or preparation.
