# CONFIDENTIALITY AGREEMENT

May 12, 2025

In connection with W.K.S. Restaurant Corporation's (collectively, "you" or "your") consideration of a possible negotiated acquisition (the "Transaction") of El Pollo Loco Holdings, Inc., a Delaware corporation (collectively with its subsidiaries, the "Company," "we" or "us"), you have requested certain information regarding the Company. In consideration of, and as a condition to, such information being made available to you and your Representatives (as defined below), you agree to, and to cause your Representatives to, treat, or cause to be treated, all Evaluation Material (as defined below) in accordance with the provisions of this letter agreement (this "Agreement"), and to take or abstain from taking the other actions hereinafter set forth.

1. Certain Definitions. For purposes of this Agreement, (i) "Evaluation Material" shall mean any and all information (whether oral, written, visual or electronic, and whether or not identified as being proprietary and/or confidential) concerning the Company or its affiliates or franchisees that is furnished or otherwise made available or provided to you or any of your Representatives by or on behalf of the Company or any of its Representatives, including, without limitation, information regarding facilities, sales figures, profit or loss figures, customer, client and supplier information, information relating to the Company, its franchisees or their respective businesses (including, without limitation, technical, business, financial, customer development plans, compilations, trade secrets, know-how, designs and strategies), the Company's business policies or practices, notes, analyses, compilations, summaries, data, studies, interpretations, forecasts, records, memoranda, information received from others that the Company is obligated to treat as confidential, and other documents and information prepared by you or your Representatives, or otherwise on your or their behalf, to the extent that they contain, reflect, summarize, or are based, in whole or in part, on any such information, (ii) the term "Representatives" means, as to any party, such party's affiliates (excluding portfolio companies) and its and their respective directors, officers, employees, agents, advisors, consultants, persons listed on Exhibit A and controlling persons of the foregoing, provided, as applied to you, without the Company's prior written consent (such consent not to be unreasonably withheld), the term "Representative" shall not include (x) any actual or potential debt or equity financing source, (y) other than the persons listed on Exhibit A, any actual or potential co-investor, co-bidder or person acting as a principal with you in connection with the Transaction (or any of their respective representatives or advisors), (excluding any person listed on Exhibit A) or (z) your portfolio companies (whether or not you control or own the majority of the equity securities of any such portfolio company), (iii) the term "person" shall be interpreted broadly to include, without limitation, any corporation, company, joint venture, partnership, trust, association, entity, individual, governmental authority (or any department, agency or political subdivision thereof) group (as such term is used in Rule 13d-5(b)(1) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")) or other entity, (iv) the term "affiliate" shall have the meaning ascribed to such term in Rule 12b-2 of the Exchange Act, provided, that, with respect to you,

Docusign Envelope ID: 025D855F-7097-490B-8C07-4A54BA66D2EC

"affiliates" shall include portfolio companies, whether or not you control or own the majority of the equity securities of any such portfolio company, (v) the term "beneficial owner" or similar terms such as "beneficially" or "beneficial ownership" shall have the meaning ascribed to such terms in Rule 13d-3 and Rule 13d-5 under the Exchange Act, and (vi) the term "control" or similar terms such as "controlled by" shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of a person, whether through the ownership of voting securities, by contract or otherwise.

Notwithstanding the foregoing, the term "Evaluation Material" does not include information that (i) is already in your or your Representative's possession (as can be confirmed by your or such Representative's records and files) and was received on a non-confidential basis from a source other than the Company or its Representatives (provided that such source was reasonably believed by you or such Representative not to be bound by a confidentiality obligation to the Company or any other person), (ii) is or becomes generally available to the public other than as a result of a direct or indirect disclosure by you or your Representatives in violation of this Agreement or other obligation of confidentiality to the Company, (iii) becomes available to you or your Representatives on a non-confidential basis from a source other than the Company or its Representatives (provided that such source was reasonably believed by you or such Representative not to be bound by a confidentiality obligation to the Company or any other person) or (iv) is demonstrated by you or your Representatives to have been independently developed by you or your Representatives without use of, reference to or reliance on, any Evaluation Material or any information from a source bound by a confidentiality obligation to the Company with respect to such information.

2. Use and Disclosure of Evaluation Material. You and your Representatives (a) shall use the Evaluation Material and the Transaction Information solely for the purpose of evaluating, negotiating and, if applicable, consummating, the Transaction in accordance with the terms of this Agreement and (b) shall keep the Evaluation Material and the Transaction Information strictly confidential and shall not, without the Company's prior written consent, disclose Evaluation Material or Transaction Information to any other person in any manner whatsoever, in whole or in part, except as permitted by Section 6 and except that the Evaluation Material may be disclosed to your Representatives to the extent that they need to know such information for the purpose of assisting you in evaluating, negotiating and, if applicable, consummating the Transaction if prior to such disclosure your Representatives are informed of the confidential nature of the Evaluation Material and the Transaction Information and agree to be bound by the terms of this Agreement to the same extent as if they were parties hereto. You agree to undertake all reasonable security precautions, at least as great as the precautions you take to protect your own confidential information that you do not desire to disclose or disseminate, to safeguard and protect the confidentiality of the Evaluation Material and the Transaction Information, and you will not otherwise use the Evaluation Material for your benefit or the benefit of others. You shall be responsible for any breach or threatened breach of this Agreement by any of your Representatives including, without limitation, any actions or inactions by your Representatives that would constitute a breach or threatened breach of this Agreement if such Representatives were parties hereto

Docusign Envelope ID: 025D855F-7097-490B-8C07-4A54BA66D2EC

or any breach or threatened breach of any instructions or directions given by you to your Representatives pursuant to the terms of this Agreement, and you shall take all reasonable measures to restrain your Representatives from any such breach or threatened breach, provided that you will not be responsible for any Representative that has entered into a confidentiality agreement directly with the Company.

3. **Competitively Sensitive Information.** It is understood and agreed that the Company may, from time to time, determine that disclosure of certain of its competitively sensitive Evaluation Material to you and/or certain of your Representatives may be inappropriate, in which case such competitively sensitive Evaluation Material may, at the Company's discretion, be made available to you or your Representatives only in accordance with additional procedures mutually agreed by the parties in writing to permit disclosure of such competitively sensitive Evaluation Material in an appropriate manner.

4. **No Discussions with Third Persons.** You agree that neither you nor any of your affiliates or any of your or their Representatives acting on your or their behalf shall enter into any exclusivity, lock-up, dry-up or other agreement, arrangement or understanding, whether written or oral, that may reasonably be expected to restrict, limit or otherwise impair the ability of any person or any of its affiliates to serve as a financing source for, or to be a co-investor, co-bidder or otherwise act as a principal with, any other person in a transaction with or involving the Company. You hereby represent and warrant that as of the date hereof, neither you nor any of your affiliates or Representatives acting on your or their behalf have, directly or indirectly, had any joint or co-bidding discussions or negotiations with any persons other than solely between and among you and your Representatives regarding the Transaction or entered into any agreement, arrangement or understanding, whether written or oral, with any other person relating to debt or equity financing of the Transaction or such other person acting as a co-bidder, co-investor, or principal with you in connection with the Transaction.

5. **Transaction Information.** Without the Company's prior written consent, except as required by law or permitted by Section 6, you shall and shall instruct your Representatives not to disclose to any person that Evaluation Material has been furnished or made available to you or your Representatives or that you or your Representatives have requested, received or reviewed any portion thereof, the existence or contents of this Agreement, that you or the Company are considering the Transaction, that investigation, discussions or negotiations are taking place or have taken place concerning the Transaction, any of the terms, conditions or other facts or information with respect to the Transaction or such investigation, discussions or negotiations, including, without limitation, the status, the identity of the parties thereto or termination thereof (collectively, the "Transaction Information"). Similarly, without your prior written consent, neither the Company nor any of its Representatives, including, for the avoidance of doubt, Jefferies LLC ("Jefferies") will disclose your identity or any terms or conditions of a potential transaction with you to any other person, including any prospective acquirer of, or investor in, the Company.

6. **Compelled Disclosure.** In the event that you or any of your Representatives are required by a governmental authority to disclose all or any part of the Evaluation

Docusign Envelope ID: 025D855F-7097-490B-8C07-4A54BA66D2EC

Material or the Transaction Information pursuant to oral questions, interrogatories, requests for information or documents, civil investigative demand, the terms of a subpoena or order issued by a court or other governmental body or similar legal process pursuant to applicable law or regulation, you shall, unless prohibited by law, (a) promptly (and in any event prior to any disclosure) notify the Company in writing of the existence, terms and circumstances surrounding such requirement (including a copy thereof), (b) cooperate with the Company to take legally available steps to resist or narrow such requirement and obtain an appropriate protective order or other remedy and (c) if disclosure of such information is required, disclose only the portion of such information that you are or such Representative is advised by outside legal counsel is legally required to be disclosed and, in such event, will exercise reasonable efforts to obtain an order or other reliable assurance that confidential treatment shall be accorded to such information and will otherwise give the Company written notice (unless prohibited by law) of such required disclosure as far in advance as reasonably practicable. For the avoidance of doubt, it is understood and agreed that you shall not be deemed to be legally required to disclose any Evaluation Material or Transaction Information solely by virtue of the fact that, absent such disclosure, you would be prohibited from purchasing, selling or engaging in derivative or other voluntary transactions with respect to the securities of the Company or that you 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.

7. Standstill. You represent and warrant to the Company that, as of the date hereof, you and your affiliates do not own (whether beneficially, constructively or synthetically through any derivative, hedging or trading position) any securities of the Company or Derivative Securities (as defined below), except for those securities listed on Exhibit B. You agree that, for a period of twelve (12) months after the date hereof (the "Standstill Period"), you will not (and will cause your affiliates and any person acting on behalf of, or in concert with, you or any of your affiliates not to), directly or indirectly:

(a) acquire, offer or propose (except as permitted under clause (d) of this Section 7) to acquire, solicit an offer to sell or agree to acquire, directly or indirectly, alone or in concert with others, by purchase or otherwise, (i) any economic interest in, or any direct or indirect right to direct the voting or disposition of any securities of the Company, whether or not any of the foregoing would give rise to beneficial ownership (as such term is used in Rule 13d-3 and Rule 13d-5 under the Exchange Act), (ii) any other direct or indirect interest in any securities of the Company or any direct or indirect rights, warrants or options to acquire, or securities convertible into or exchangeable for, any securities of the Company, (iii) any contracts or rights in any way related to the acquisition or price of securities or interests of the Company (whether beneficially, constructively or synthetically through any derivative or trading position or otherwise) (each of clauses (ii) and (iii), "Derivative Securities") or (iv) any indebtedness of the Company;

(b) make, or in any way participate in, directly or indirectly, alone or in concert with others, any "solicitation" of "proxies" (as such terms are used in the proxy

Docusign Envelope ID: 025D855F-7097-490B-8C07-4A54BA66D2EC

rules of the Securities and Exchange Commission promulgated pursuant to Section 14 of the Exchange Act) or seek to advise or influence in any manner whatsoever any Person with respect to the voting of any securities of the Company, or seek the consent of any Person with respect to any securities or interests of the Company;

(c) form, join or any way participate in a "group" within the meaning of Section 13(d)(3) of the Exchange Act with respect to any voting securities of the Company or otherwise in connection with any of the actions prohibited by this Section 7;

(d) make any public announcement with respect to, or solicit or submit a proposal for, or offer of, any merger, consolidation, business combination, tender or exchange offer, recapitalization, reorganization, purchase or other similar extraordinary transaction involving, the Company or its securities or interests, except a nonpublic proposal to the Company's board of directors that would not reasonably be expected to require the Company or any other Person to make any public announcement or other disclosure with respect thereto;

(e) otherwise seek, alone or in concert with others, to control, change or influence the management, board of directors or policies of the Company or nominate any Person as a director, or convene a meeting of the shareholders of the Company or propose any matter to be voted upon by the shareholders of the Company;

(f) make any request or proposal to amend, waive or terminate any provision of this Section 7, contest the validity or enforceability of this Agreement or seek a release of the restrictions contained herein (whether by legal action or otherwise);

(g) announce an intention to do, or enter into any arrangement or understanding or discussions with any other Person(s) to do, any of the actions restricted or prohibited by this Section 7; or

(h) take any action that could result in the Company having to make a public announcement regarding any of the matters referred to in this Section 7.

Notwithstanding anything to the contrary in this Section 7, nothing in this Agreement shall prevent you and your affiliates from (i) making any offer or entering into any transaction with respect to, or otherwise consummating, any transaction with the Company in the ordinary course of business via license, franchise, development, consultancy, collaboration, joint venture arrangement or the parties' on-going business relationships, (ii) making passive investments by a pension or employee benefit plan or trust for your and your affiliates' employees so long as such investments (including trading) are directed by independent trustees or administrators who have not received and do not have access to Evaluation Material or Transaction Information and such investments do not require you or your affiliates to file a Schedule 13D or 13G with the SEC with respect to the Company's

Docusign Envelope ID: 025D855F-7097-490B-8C07-4A54BA66D2EC

securities, or (iii) purchasing securities of the Company resulting in ownership of up to five percent (5%), in the aggregate, of the outstanding securities of the Company.

Notwithstanding anything to the contrary in this Agreement, (A) any action or statement by you or any of your Representatives taken after expiration or termination of the Standstill Period that would have been restricted by this Section 7 if such action or statement had been taken before expiration or termination of the Standstill Period shall not be, and shall be deemed not to be breach of this Agreement, subject to compliance with the other restrictions contained in this Agreement and (B) in the event you or any of your affiliates makes an offer with respect to a Transaction after expiration or termination of the Standstill Period, you and your affiliates may, in connection therewith, make disclosures of Evaluation Material to the extent that that such disclosure is in compliance with Section 6, provided you shall provide the Company with reasonable notice (which shall not be less than 24 hours' advance notice), including the draft of such disclosure, prior to the disclosure thereof.

8. Non-Solicitation; Non-Hire. You hereby agree that, for a period of eighteen (18) months after the date hereof, without obtaining the prior written consent of the Company, neither you nor any of your affiliates nor any of your or their Representatives acting on your or their behalf will, directly or indirectly, solicit, or cause to be solicited (or otherwise encourage any other person to solicit), for employment, independent contracting or consulting arrangements, or employ or engage, or cause to be employed or engaged (or otherwise encourage any other Person to employ or engage), whether on a full-time, part-time, independent contracting, consulting or other basis, any officer or employee of the Company at the general manager level or above; provided, however, that you shall not be prohibited from (a) soliciting for employment any person through bona fide general solicitations, including through recruiting firms (provided that such general solicitation is not specifically targeted at directors, officers or employees of the Company) and (b) soliciting for employment or employing any person who has been terminated by the Company at least six (6) months prior to commencement of any solicitation or employment discussions (so long as such person was not otherwise solicited in violation of this Agreement). Further, you agree that you and your Representatives acting on your behalf will not, without the prior written consent of the board of directors of the Company, engage in discussions with management or the officers of the Company regarding the terms of their compensation or any post-Transaction employment or equity participation as part of, or in connection with or after a potential Transaction.

Docusign Envelope ID: 025D855F-7097-490B-8C07-4A54BA66D2EC

so requests in writing at any time, you shall (and shall cause your Representatives to) promptly (and in no event later than ten (10) business days following such notice or request) either (at your sole election and expense) (a) deliver to the Company all of the Evaluation Material in your possession or in the possession of any of your Representatives or (b) destroy all Evaluation Material in your possession or in the possession of any of your Representatives (such delivery or destruction to be certified in writing by you), it being understood that neither you nor your Representatives shall be required to erase (but neither you nor your Representatives may use) electronically stored Evaluation Material that has been saved to a back-up file in accordance with applicable law or your or your Representatives' applicable bona fide document retention policies adopted for purposes of compliance with such laws so long as such Evaluation Material is not accessed by you or your Representatives other than in accordance with Section 6; provided that any such retained Evaluation Material shall remain subject to the terms of this Agreement for so long as you or your Representatives retain such Evaluation Material. You hereby acknowledge that all Evaluation Material is and shall remain the property of the Company.

10. Trading Restrictions. You hereby acknowledge that you are aware, and that you will advise your Representatives who are informed as to the matters which are the subject of this Agreement, that (i) the Evaluation Material being furnished to you and the Transaction Information contains or may itself be material, non-public information about the Company and (ii) the United States securities laws, including Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder, prohibit any person who is in possession of material, non-public information concerning securities of an issuer 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.

11. No Obligation, Representation or Warranty. The Company shall not be obligated to furnish or otherwise make available any Evaluation Material that it determines in its sole discretion not to disclose. You understand that neither the Company nor any of its Representatives has made or makes any express or implied representation or warranty as to the accuracy or completeness of the Evaluation Material or any other information provided to you or your Representatives in connection with this Agreement and that, except as may be provided in a Definitive Agreement (as defined below) when, as and if executed, nothing contained in any discussions between you or any of your Representatives and the Company or any of its Representatives shall be deemed to constitute an express or implied representation or warranty. You agree that neither the Company nor its Representatives shall have (and the Company and its Representatives hereby expressly disclaim) any liability

Docusign Envelope ID: 025D855F-7097-490B-8C07-4A54BA66D2EC

to you or any other person (including your Representatives) resulting from the use or content of the Evaluation Material or any other information provided to you or your Representatives in connection with this Agreement or from any action taken or any inaction occurring in reliance on such Evaluation Material or information, except as may be included in (and in accordance with the terms and conditions of) any Definitive Agreement when, as and if executed. You agree that unless and until a definitive written agreement between you and the Company providing for a Transaction (a "Definitive Agreement"), if any, has been executed and except for the matters set forth herein, neither you nor the Company will be under any legal obligation with respect to a Transaction by virtue of this Agreement or any written or oral expression with respect to such Transaction by any of their respective Representatives.

The Company and its Representatives are free, in their sole discretion, to determine (i) to conduct or not conduct any process for the Transaction or any other transaction involving the Company (including negotiating with any of the other prospective parties thereto and entering into a definitive written agreement providing for a transaction involving the Company without prior notice to you or any other person) or to determine not to proceed with any transaction (whether involving you or any other person); (ii) to provide or not provide Evaluation Material to you or your Representatives under this Agreement (or to determine that certain Evaluation Material shall only be disclosed to certain Representatives (and not others) or otherwise generally subject to special procedures or restrictions that do not otherwise apply generally to other Evaluation Material); (iii) to reject any and all proposals made by you or any of your Representatives with regard to the Transaction; and (iv) to terminate discussions and negotiations at any time for any reason or no reason. No representation or warranty (whether express or implied) has been made by the Company or any of its Representatives with respect to the proposed process or the manner in which the proposed process is conducted, and you hereby disclaim any such representation or warranty. Any procedures relating to any process for the Transaction or any other transaction may be changed at any time without notice to you or any other person. You agree that none of the Company or any of its Representatives has any legal, fiduciary or other duty to you with respect to the manner in which the proposed process is conducted. You agree that neither the Company nor any of its subsidiaries has granted you or any of your Representatives any license, copyright, or similar right with respect to any of the Evaluation Material or any other information provided to you or any of your Representatives by the Company or its Representatives.

12. Term. Except as otherwise provided in this Agreement, the term of this Agreement shall terminate and the terms and conditions shall cease to have force and effect on the earlier of (a) two (2) years from the date hereof and (b) consummation of the Transaction; provided that such termination shall not relieve you or your Representatives of your or their respective responsibilities in respect of any breach of this Agreement prior to

Docusign Envelope ID: 025D855F-7097-490B-8C07-4A54BA66D2EC

such termination; provided, further, that in the case of trade secrets, the term of this Agreement shall be the maximum period permitted by law.

Each party agrees not to commence any action, suit or proceeding relating thereto except in the courts described above in Delaware, other than actions in any court of competent jurisdiction to enforce any judgment, decree or award rendered by any such court in Delaware as described herein. Each party hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any action or proceeding arising out of or relating to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the courts in Delaware as described herein for any reason; (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise); and (c) that (i) the suit, action or proceeding in any such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper, or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. EACH PARTY AND EACH OF ITS REPRESENTATIVES BOUND TO THE TERMS HEREOF HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY AND ALL RIGHTS TO A JURY TRIAL IN RESPECT OF ANY CLAIM OR CAUSE OF ACTION IN ANY COURT IN ANY JURISDICTION BASED UPON OR ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY AMENDMENT HEREOF.

course of business unrelated to the Transaction, so long as no Evaluation Material or Transaction Information is disclosed in connection therewith.

## 18. Miscellaneous.

(a) It is further understood and agreed that no failure or delay by either party in exercising any right, power or privilege under this Agreement or failure by a party to insist on strict performance of its obligations hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any right, power or privilege hereunder. Any waiver by either party hereto of a breach of any provision of this Agreement shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Agreement. This Agreement represents the entire understanding of the parties with respect to the matters referred to in this Agreement and supersedes all prior and contemporaneous understandings, written or oral, between the parties with respect to such matters.

(b) In the event there is any conflict or inconsistency between this Agreement and the terms and conditions of any electronic data room now or hereafter applicable to you or your Representatives with respect to Evaluation Material provided to you or your Representatives hereunder, the terms and conditions of this Agreement shall govern and constitute the terms and conditions with respect to the access of such Evaluation Material by you or you Representatives in any such electronic data room.

(c) Each party acknowledges that the other party would be immediately and irreparably injured by any actual or threatened breach of this Agreement by such party or its Representatives, and that money damages are an inadequate remedy for any actual or threatened breach of this Agreement because of the difficulty of ascertaining the amount of damage that will be suffered by non-breaching party in the event of a breach of this Agreement. Therefore, each party agrees, on behalf of itself and its Representatives, that both parties shall be entitled to seek specific performance of this Agreement and injunctive or other equitable relief as a remedy for any such breach or threatened breach, and further waive any requirement for proving actual damages or the securing or posting of any bond in connection with any such remedy. Such remedy shall not be deemed to be the exclusive remedy for any such breach of this Agreement, but shall be in addition to all other remedies available at law or equity to the non-breaching party.

(d) The provisions of this Agreement shall be severable in the event that any of the provisions hereof are held by a court of competent jurisdiction to be invalid, void or otherwise unenforceable. It is hereby stipulated and declared to be the intention of the parties that they would have executed the Agreement had the terms, provisions, covenants, and restrictions which may be hereafter declared invalid, void, or unenforceable not initially been included herein. If a court of competent jurisdiction determines that any restriction or portion thereof is overly restrictive and unenforceable, the court may reduce or modify such restriction to those which it deems reasonable and enforceable under the circumstances, and the parties agree to request the court to exercise such power, and, as so reduced or modified, the parties hereto agree that the restrictions contained herein shall remain in full force and effect, shall be enforceable, and shall be enforced.

(e) Any assignment, in whole or in part, of this Agreement (or any of the rights and obligations herein) by a party without the prior written consent of the other party hereto shall be void, provided, the Company may, without your consent, assign this Agreement to an affiliate or a successor-in-interest in connection with a merger, reorganization, sale of all or substantially all of its assets or similar business combination transaction. Any provision of this Agreement may be waived by the party entitled to the benefit thereof, if in writing and signed by the party entitled to the benefit thereof. This Agreement may be executed by manual, facsimile or electronic signature in one or more counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same instrument.

You hereby confirm that you have all requisite power and authority, including any necessary approval by your governing body, to execute and deliver this Agreement and to perform your obligations hereunder.

**(b) Name of Issuer:**
El Pollo Loco Holdings, Inc.

**(c) Address of Issuer's Principal Executive Offices:**
3535 Harbor Blvd., Suite 100, Costa Mesa, CA, 92626

This Schedule 13D represents Amendment No. 1 to the Schedule 13D filed by CSIP VI Corporation Acquisitions, LP, CSFC Financing I, LLC, CSFC Management Company, LLC, CapitalSpring Finance Company, LLC, and Richard Fitzgerald (the "CapitalSpring Reporting Persons") on May 29, 2025, and an initial filing on Schedule 13D for the WKS Reporting Persons (as defined in Item 2(a) hereof).

**Item 4. Purpose of Transaction**

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

As previously disclosed, on May 21, 2025, CapitalSpring entered into a Confidentiality Agreement with the Issuer. Also on May 21, 2025, WKS Corporation entered into a substantially similar confidentiality agreement with the Issuer (the "WKS Confidentiality Agreement"), a copy of which is attached hereto as Exhibit 4 and incorporated by reference into this Item 4. Representatives of CapitalSpring have continued to engage in discussions with the Issuer's management and other third parties, including WKS Corporation, with regard to a potential extraordinary transaction involving the Issuer and other third parties, with which CapitalSpring and WKS Corporation may participate, together or separately, as investors, financing sources, or otherwise. There is no assurance that any such transaction will develop or materialize, or if it does, as to its timing or whether the Reporting Persons will participate.

The Reporting Persons expect to continuously review their investment in the Issuer. Except as indicated herein, no Reporting Person, as a stockholder of the Issuer, has any plans or proposals that relates or would result in any of the transactions or other matters specified in clauses (a) though (j) of Item 4 of Schedule 13D. Each Reporting Person may, at any time and from time to time, review or reconsider its or his position and/or change its or his purpose and/or formulate plans or proposals with respect thereto.

The information set forth in Item 2(c) and Item 4 of this Amendment No. 1 to Schedule 13D is incorporated into this Item 5(a) by reference. The CapitalSpring Reporting Persons and the WKS Reporting Persons, if aggregated together, hold approximately 1,662,520 Shares, representing approximately 5.5% of the outstanding Shares. The filing of this Schedule 13D shall not be construed as an admission that the Reporting Persons are, for purposes of the Exchange Act, the beneficial owners of any of the securities reported herein or that they are members of a "group." The Reporting Persons expressly disclaim the existence of, or membership in, a "group" within the meaning of Section 13(d)(3) of the Act and Rule 13d-5(b) thereunder consisting of the CapitalSpring Reporting Persons and the WKS Reporting Persons, and the CapitalSpring Reporting Persons disclaim beneficial ownership with respect to any Shares beneficially owned by the WKS Persons, and the WKS Reporting Persons disclaim beneficial ownership of the shares beneficially owned by the CapitalSpring Reporting Persons, and neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by any Reporting Person that it is the beneficial owner of any of the shares of common stock referred to herein for purposes of Section 13(d) of the Act, or for any other purpose.

**(b)**
See rows (7) through (10) of the cover page to this Schedule 13D for the number of Shares as to which each Reporting Person has the sole or shared power to vote or direct the vote and sole or shared power to dispose or to direct the disposition.
