ITEM 1.01 Entry into a Material Definitive Agreement

On, April 7, 2026, Catalyst Bancorp, Inc., a Louisiana corporation ("Catalyst Bancorp"), and Catalyst Bank, a federally-chartered savings bank and wholly-owned subsidiary of Catalyst Bancorp, entered into an Agreement and Plan of Share Exchange and Merger (the “Merger Agreement”) with Lakeside Bancshares, Inc., a Louisiana corporation ("Lakeside Bancshares"), and Lakeside Bank, a Louisiana banking corporation and the wholly-owned subsidiary of Lakeside Bancshares. The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, Catalyst Bancorp will acquire shares of Lakeside Bancshares by exchange (“Share Exchange”) of cash for outstanding Lakeside Bancshares common stock (“Lakeside Common Stock”), followed immediately by the merger of Lakeside Bancshares into Catalyst Bancorp and Lakeside Bank into Catalyst Bank (“Mergers”), with Catalyst Bancorp and Catalyst Bank continuing as the surviving entities of the Mergers. Subject to the terms and conditions of the Merger Agreement, which has been unanimously approved by the Boards of Directors of Catalyst Bancorp and Lakeside Bancshares, upon completion of the Mergers, shareholders of Lakeside Bancshares (other than holders of Dissenting Shares, as such term is defined in the Merger Agreement) will receive $19.58 in cash for each outstanding share of Lakeside Bancshares common stock, or $41.1 million in aggregate, subject to adjustment under certain circumstances.

The Merger Agreement contains customary representations and warranties from both Catalyst Bancorp and Lakeside Bancshares, and each have agreed to customary covenants, including, among others, covenants relating to: (1) the conduct of Lakeside Bancshares’ business during the interim period between the execution of the Merger Agreement and the completion of the Mergers; (2) Lakeside Bancshares’ obligation to convene and hold a meeting of its shareholders to consider and vote upon the approval of the Mergers, the Merger Agreement and the other transactions contemplated by it; and (3) subject to certain exceptions, the recommendation by the Board of Directors of Lakeside Bancshares in favor of the approval by its shareholders of the Mergers, the Merger Agreement and the other transactions contemplated it. Lakeside Bancshares has also agreed not to (1) solicit proposals relating to alternative business combination transactions or (2) subject to certain exceptions, enter into any discussions, or enter into any agreement, concerning, or provide confidential information in connection with, any proposals for alternative business combination transactions.

Concurrently with the execution of the Merger Agreement, each director of Lakeside Bancshares and Lakeside Bank owning or controlling shares of Lakeside Common Stock, in their respective capacities as shareholders or beneficial owners of common stock of the company, entered into Support Agreements with Catalyst Bancorp under which they agreed to vote their shares of Lakeside Bancshares in favor of the Mergers and to take certain other actions that would support the completion of the Mergers. The form of Support Agreement is attached to the Merger Agreement as Exhibit A-1 thereto.

In addition, each director of Lakeside Bancshares and Lakeside Bank owning or controlling shares of Lakeside Common Stock, in their respective capacities as shareholders or beneficial owners of common stock of the company, entered into Restrictive Covenant Agreements with Catalyst Bancorp under which they agreed to not compete with Catalyst Bancorp following closing, among other things. The form of Restrictive Covenant Agreement is attached the Merger Agreement as Exhibit A-2 thereto.

Completion of the Merger is subject to certain customary conditions, including, among others, (1) approval of the Merger Agreement by the requisite vote of the shareholders of Lakeside Bancshares; (2) receipt of required regulatory approvals; and (3) the absence of any injunction, order or other legal restraint prohibiting the completion of the Merger. Each party’s obligation to complete the Merger is also subject to certain additional customary conditions, including (1) subject to certain exceptions, the accuracy of the representations and warranties of the other party and (2) performance in all material respects by the other party of its obligations under the Merger Agreement. Subject to the receipt of all required approvals and the satisfaction of all other conditions, the Merger is expected to be completed in the third quarter of 2026.

The foregoing description of the Mergers and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto and is incorporated herein by reference.

ITEM 7.01 Regulation FD Disclosure

ITEM 8.01 Other Events

Forward-Looking Statements

This Current Report contains, and the officers and directors of Catalyst Bancorp and its subsidiary may from time to time make, forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, which are typically identified bywords or phrases such as “may,” “will,” “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “target,” “forecast,” and other words and terms of similar meaning. Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties.

Catalyst Bancorp cautions readers that any forward-looking statement is not a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking statements. Such forward-looking statements include but are not limited to statements about the benefits of the proposed merger involving Catalyst Bancorp and Lakeside Bancshares and their subsidiaries, including future financial and operating results; statements about Catalyst Bancorp’s plans, objectives, expectations and intentions; statements about the expected timing of completion of the proposed merger; and other statements that are not historical facts. Important factors that could cause actual results to differ materially from those indicated by such forward-looking statements include risks and uncertainties relating to: (i) the ability to obtain the requisite shareholder approvals; (ii) the risk that Catalyst Bancorp may be unable to obtain governmental and regulatory approvals required to consummate the proposed merger, or required governmental and regulatory approvals may delay the merger or result in the imposition of conditions that could cause the parties to abandon the merger; (iii) the risk that a condition to closing may not be satisfied; (iv) the timing to consummate the proposed merger; (v) the risk that the businesses will not be integrated successfully; (vi) the risk that the cost savings and any other synergies from the proposed merger may not be fully realized or may take longer to realize than expected; (vii) disruption from the proposed merger making it more difficult to maintain relationships with customers, employees or vendors; (viii) the diversion of management time on merger-related issues; and (ix) other factors which Catalyst Bancorp discusses or refers to in its reports (such as the Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-k) and other subsequent filings with the SEC, which are available on Catalyst’s website or at the SEC’s website at www.sec.gov.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on any forward-looking statement as a prediction of future events. Any forward-looking statement speaks only as of the date on which it is made, and except as required by law, Catalyst Bancorp expressly disclaims any obligation to update its forward-looking statements whether as a result of new information, future events or otherwise. All subsequent written and oral forward-looking statements concerning the proposed transaction or other matters attributable to Catalyst Bancorp or any person acting on its behalf are expressly qualified in their entirety by the cautionary statements above.

Opelousas, Louisiana – Catalyst Bancorp, Inc. (Nasdaq: “CLST”) (“Catalyst”), the parent company for Catalyst Bank (www.catalystbank.com), and Lakeside Bancshares, Inc. (OTC Markets: “LKSB”) (“Lakeside”), the parent company for Lakeside Bank, announced today the signing of a definitive Agreement and Plan of Share Exchange and Merger (the "Merger Agreement") under which Catalyst will acquire Lakeside in an all-cash transaction. The Merger Agreement also provides that Lakeside will be merged with and into Catalyst, with Catalyst surviving, and that Lakeside Bank will be merged with and into Catalyst Bank, with Catalyst Bank surviving. Once the transaction closes, Lakeside’s shareholders (other than dissenting shares) will receive $19.58 per share in cash, or $41.1 million in aggregate, subject to adjustment under certain circumstances.

“Lakeside Bank has built a tremendous reputation across Southwest Louisiana,” said Joe Zanco, President and CEO of Catalyst Bank. "Bringing our organizations together allows us to build on that strong foundation. We look forward to working with the team at Lakeside to enhance our collective investment in growing the region’s economy.”

“This transaction more than doubles the size of our company,” continued Mr. Zanco, “and significantly enhances our earnings and future growth potential. Our leadership team’s merger experience positions us to immediately play offense in adding customers in Southwest Louisiana.”

Lakeside operates four (4) branch locations in Calcasieu Parish. As of December 31, 2025, Lakeside had assets of $385.7 million, $236.3 million in loans and $287.5 million in deposits.

“Our decision to join forces with Catalyst Bank comes from a place of strength and long-term vision,” said Roy Raftery, President and CEO of Lakeside Bank. “This partnership allows us to preserve the relationships and community focus that define our bank while gaining the scale, technology, and resources needed to serve our customers even better in the years ahead.”

The Merger Agreement was unanimously approved by the boards of directors of both companies. The transaction is expected to close in the third quarter of 2026, subject to customary closing conditions, including regulatory approvals and Lakeside shareholder approval.

Catalyst anticipates the transaction will be over 180% accretive to earnings per share once cost savings are fully realized and accretive to tangible book value per share within 3 years of closing. Following the Merger, Catalyst Bank’s capital position is expected to remain strong with leverage and total risk-based capital ratios of approximately 10.4% and 15.4%, respectively. No additional capital will be needed by Catalyst to complete the transaction.

other words and terms of similar meaning. Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties. Catalyst

Important Information and Disclaimers

Trademark and Tradenames; Industry and Market Data

This Presentation includes trademarks, tradenames and service marks that are the property of other organizations. Solely for convenience, trademarks and tradenames may appear

without the ® and symbols, but those references are not intended to indicate, in any way, that Catalyst will not assert, to the fullest extent under applicable law, its rights or that the

applicable owner will not assert its rights, to these trademarks and tradenames. The market data and certain other statistical information included in this Presentation are based on a

variety of sources, including independent industry publications, government publications and other published independent sources. Some data is also based on Catalyst’s good faith

estimates, which have been derived from management’s knowledge and experience in the industry in which Catalyst operates. Although Catalyst has not independently verified the

accuracy or completeness of the third-party information included in this Presentation, based on management’s knowledge and experience, Catalyst believes that these third-party sources

are reliable and that the third-party information is accurate and complete. However, such data involves risks and uncertainties and is subject to change based on various factors.

Pro Forma Financial Information

The pro forma financial and other information included in this Presentation is based on management’s good faith estimates and assumptions as of the date hereof. However, Catalyst

will not finalize the purchase price allocation, the final assessment of fair values of assets and liabilities, and actual transaction expenses until the proposed acquisition of Lakeside

Bancshares, Inc. has been completed. Differences between these preliminary estimates and the final acquisition accounting will occur and these differences could have a material

impact. In addition, the pro forma information included in this Presentation is for illustrative and informational purposes only and is not necessarily indicative of what the combined

company’s financial position would have been had the acquisition been completed as of the dates indicated or the future financial position of the combined company, assuming such

acquisition is completed.

Non-GAAP Financial Measures

This Presentation contains certain financial information determined by methods other than in accordance with generally accepted accounting principles in the United States of America

(“GAAP”). These measures and ratios include “tangible common equity” and “tangible book value.” Management believes these non-GAAP financial measures provide information useful

to investors in understanding Catalyst’s financial results, and that its presentation, together with the accompanying reconciliations, provide a more complete understanding of factors and

trends affecting Catalyst’s business and allows investors to view performance in a manner similar to management, the entire financial services sector, bank stock analysts and bank

regulators. These non-GAAP measures are intended to supplement, not substitute for, comparable GAAP measures. Because non-GAAP financial measures are not standardized, it may

not be possible to compare these financial measures with other companies’ non-GAAP financial measures having the same or similar names. A reconciliation of the non-GAAP financial

measures disclosed in this Presentation are included in the Appendix.

Nothing contained in this presentation is or will be deemed to be, or construed as, any advice or recommendation to the recipient or any third parties as to whether or not such parties

should enter into any transaction(s), make any investment, or take any investment, accounting, or corporate action in connection therewith. The delivery of this presentation will not, under

any circumstances, create any implication that there has been no change in the affairs of Catalyst after the date hereof, and Catalyst assumes no obligation to update such information,

except to the extent required by applicable law.

AGREEMENT AND PLAN OF SHARE EXCHANGE AND MERGER

This AGREEMENT AND PLAN OF SHARE EXCHANGE AND MERGER, dated as of April 7, 2026 (this “Agreement”), is made by and between Lakeside Bancshares, Inc., a Louisiana corporation (“LBI”), and Lakeside Bank, a Louisiana banking corporation (“Lakeside”), on the one hand, and Catalyst Bancorp, Inc., a Louisiana corporation (“CBI”), and Catalyst Bank, a federally-chartered savings bank (“Catalyst”), on the other hand.

RECITALS:

WHEREAS, the boards of directors of CBI and LBI each have approved, and deem it advisable and in the best interests of their respective corporations and shareholders to consummate the strategic business combination transaction provided for herein in which LBI will, subject to the terms and conditions set forth herein, be acquired by CBI by statutory share exchange (the “Share Exchange”) and then immediately thereafter merge with and into CBI (the “Corporate Merger”), with CBI as the surviving corporation (hereinafter sometimes referred to in such capacity as the “Surviving Corporation”) in the Corporate Merger;

WHEREAS, the boards of directors of Catalyst and Lakeside each have approved, and deem it advisable and in the best interests of their respective corporations and respective sole shareholders to consummate the strategic business combination transaction provided for herein in which Lakeside will, subject to the terms and conditions set forth herein, merge with and into Catalyst (the “Bank Merger”), with Catalyst as the surviving banking corporation (hereinafter sometimes referred to in such capacity as the “Surviving Bank”) in the Bank Merger;

WHEREAS, for U.S. federal income tax purposes, the parties intend (1) that the Share Exchange will be treated as if holders of shares of LBI Common Stock (as defined in Section 2.3 herein) sold their interests therein solely in exchange for cash in a taxable stock sale by such holders of shares of LBI Common Stock to CBI for federal and, if applicable, state and local income Tax purposes, (2) that the Corporate Merger will qualify as a “complete liquidation” of LBI with and into CBI within the meaning of Section 332 of the Internal Revenue Code of 1986, as amended (the “Code”), (3) that the Bank Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code (such intent, collectively, the “Intended Tax Treatment”), and (4) for this Agreement to be, and this Agreement is adopted as, a “plan of liquidation” for purposes of Section 332 of the Code with respect to the Corporate Merger and a “plan of reorganization” for purposes of Sections 354 and 361 of the Code with respect to the Bank Merger;

WHEREAS, as a material inducement and as additional consideration to CBI to enter into this Agreement, (i) each director of LBI and Lakeside owning shares of LBI Common Stock has entered into a shareholder support agreement with CBI dated as of the date hereof, the form of which is attached hereto as Exhibit A-1 (each a “Shareholder Support Agreement” and, collectively, the “Shareholder Support Agreements”), pursuant to which each such person has agreed, among other things, to vote all shares of LBI Common Stock owned by such person and which such person has the power to vote in favor of the approval of this Agreement and the transactions contemplated hereby, upon the terms and subject to the conditions set forth in this Agreement, and to refrain from transfers of any such shares of LBI Common Stock prior to the closing of the Share Exchange (the “Closing”), and (ii) non-employee directors of LBI and

#111281803v9

Lakeside have entered into a Restrictive Covenant Agreement with CBI dated as of the date hereof to be effective as of the Effective Time, the form of which is attached hereto as Exhibit A-2; and

WHEREAS, the parties desire to make certain representations, warranties, covenants and agreements in connection with the Share Exchange, Corporate Merger and Bank Merger and also to prescribe certain conditions to the Share Exchange, Corporate Merger and Bank Merger;

NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained herein, and intending to be legally bound hereby, the parties agree as follows:

ARTICLE I.

THE SHARE EXCHANGE AND MERGERS

1.1The Share Exchange.

(a)Share Exchange. At the Effective Time, CBI will acquire all of the outstanding shares of LBI Common Stock, in exchange for the Share Exchange Consideration defined in Article 2 below, pursuant to the provisions of this Agreement, the Share Exchange Agreement in substantially the form of Exhibit B hereto (the “Share Exchange Agreement”) and the provisions of and with the effect provided in La. Rev. Stat. § 12:1-1101, et seq. For U.S. federal income tax purposes, the Share Exchange is intended be treated as if holders of shares of LBI Common Stock sold their interests therein for cash.

(b)Effect of Share Exchange. Upon consummation of the Share Exchange as of the Effective Time, all of the issued and outstanding shares of LBI Common Stock shall be owned by CBI, but the separate corporate existence of LBI shall not cease until after the completion of the Corporate Merger, which is more fully described below. Until completion of the Corporate Merger, all of the assets and property of every kind and character, real, personal and mixed, tangible and intangible, choses in action, rights, and credits owned by LBI, or which would inure to it, shall remain owned by LBI, even though LBI at that time, and until the completion of the Corporate Merger, will be a wholly owned subsidiary of CBI.

1.2The Mergers.

(a)Subject to the terms and conditions of this Agreement and the Corporate Merger Agreement in substantially the form of Exhibit C hereto (the “Corporate Merger Agreement”), in accordance with the Louisiana Business Corporation Act (“LBCA”), immediately following the Share Exchange, LBI shall merge with and into CBI. CBI shall be the Surviving Corporation in the Corporate Merger, and shall continue its corporate existence under the laws of the State of Louisiana. Upon consummation of the Corporate Merger, the separate corporate existence of LBI shall terminate.

(b)Subject to the terms and conditions of this Agreement and the Bank Merger Agreement in substantially the form of Exhibit D hereto (the “Bank Merger Agreement”), in accordance with 12 U.S.C. § 1828(c), 12 U.S.C. § 1464, 12 C.F.R § 5.33, and La. Rev. Stat. § 6:351, et seq., as amended, immediately following the Corporate Merger, Lakeside shall merge with and into Catalyst. Catalyst shall be the Surviving Bank in the Bank Merger and shall continue

#111281803v9

its corporate existence under the laws of the United States of America. Upon consummation of the Bank Merger, the separate corporate existence of Lakeside shall terminate.

1.3Effective Time.

(a)The Share Exchange shall become effective on such date and at such time as set forth in the Articles of Share Exchange (the “Articles of Share Exchange”) that shall be filed with the Secretary of State of Louisiana (the “Louisiana Secretary”) on the Closing Date; provided, that the parties shall cause the Share Exchange to be effective no later than the day immediately following the day on which the Closing occurs (referred to in this Agreement as the “Closing Date.”). The “Effective Time” shall be the date and time when the Share Exchange becomes effective, as set forth in the Articles of Share Exchange.

(b)The Corporate Merger shall become effective on such date and at such time as set forth in the articles of merger of CBI and LBI (the “Articles of Merger”) that shall be filed with the Louisiana Secretary on the Closing Date; provided, that the parties shall cause the Corporate Merger to be effective immediately following the Effective Time.

(c)The Bank Merger shall become effective immediately following the Corporate Merger and as set forth in the Certificate of Merger Approval issued by the Office of the Comptroller of the Currency (the “OCC”) and the Louisiana Office of Financial Institutions (“OFI”) based on articles of merger of Catalyst and Lakeside filed with the OCC and the OFI and the Louisiana Secretary, as necessary (collectively, and together with such other documents and certificates as are necessary to effectuate the Bank Merger, the “Bank Merger Certificates”).

1.4Effects of the Corporate Merger and Bank Merger. At and after the Effective Time, the Corporate Merger shall have the effects set forth in La. Rev. Stat. § 12:1-1107. At and after the effective time of the Bank Merger, the Bank Merger shall have the effects set forth in 12 U.S.C. § 1828(c), 12 C.F.R. § 5.33 and La. Rev. Stat. § 6:355.

1.5Restructuring the Merger. Notwithstanding any other provision in this Agreement, the Parties may, upon mutual written agreement, restructure the Share Exchange and Mergers; provided, however, that the Share Exchange Consideration (as defined below) shall remain the same in kind and in time received and such restructuring shall not (i) materially impair or delay the consummation of the Share Exchange, (ii) require resubmission to LBI’s shareholders for approval, (iii) require resubmission to regulatory authorities for approval or be likely to delay, jeopardize receipt of, or impose a Burdensome Condition upon any required regulatory approvals, or (iv) result in any material adverse U.S. federal or state income Tax consequences to LBI’s shareholders as a result of such modification.

1.6Conversion of LBI Common Stock. The following shall occur, subject to the provisions of this Agreement, at the Effective Time, by virtue of the Share Exchange and without any action on the part of LBI, CBI or the holder of any of the following securities.

(a)Subject to Sections 1.6(b) and 1.6(d) hereof, each share of LBI Common Stock outstanding immediately prior to the Effective Time (other than (i) the shares that are cancelled pursuant to Section 1.6(c) and (ii) the shares with respect to which the holders thereof

#111281803v9

have perfected dissenters’ rights under La. Rev. Stat. § 12:1-1301, et seq. (“Part 13”) of the LBCA (the “Dissenting Shares”)), shall automatically be converted at the Effective Time into the right to receive such holder’s pro-rata share of Forty-One Million Eighty-One Thousand Four Hundred Forty Four and 14/100 Dollars ($41,081,444.14) in cash, calculated based on the total number of issued and outstanding shares of LBI Common Stock immediately before the Share Exchange, as may be adjusted by Section 1.6(b) (“Share Exchange Consideration”).

(b)In the event that, prior to Closing, the participation by Lakeside in the asset that is the subject of the legal proceeding disclosed in Section 4.9 of the LBI Disclosure Schedules (“Adjusting Asset”) is liquidated, through settlement with the lead lender or otherwise, so that Lakeside receives cash in exchange for its interest in the Adjusting Asset, the Share Exchange Consideration shall be increased on a tax adjusted basis by an amount equal to fifty cents ($0.50) for each one dollar ($1.00) of cash collected by Lakeside in satisfaction of the Adjusting Asset that exceeds One Million Dollars ($1,000,000), with no additional increase required for a recovery of Two Million Sixty-Three Dollars ($2,063,000) or more on the Adjusting Asset. For purpose of the tax-adjusted calculation, a tax rate of 21% shall be used. By way of example, should Lakeside liquidate the Adjusting Asset for $1.5 million prior to Closing, the Share Exchange Consideration shall be increased by $197,500 (i.e., 0.50 x $500,000 x (1.00 - 0.21)).

(c)All shares of LBI Common Stock issued and outstanding immediately prior to the Effective Time that are owned by CBI, LBI, Lakeside or any of their respective Subsidiaries (other than (i) shares of LBI Common Stock held in trust accounts, managed accounts and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties and (ii) shares of LBI Common Stock held, directly or indirectly, by CBI or LBI in respect of a debt previously contracted) shall be cancelled and shall cease to exist and no Share Exchange Consideration shall be delivered in exchange therefor.

(d)No Dissenting Shares shall be converted in the Merger. All such shares shall be canceled and the holders thereof shall thereafter have only such rights as are granted to dissenting shareholders under Part 13 of the LBCA; provided, however, that if any such shareholder fails to perfect his or her rights as a dissenting shareholder with respect to his or her Dissenting Shares in accordance with Part 13 of the LBCA or withdraws or loses such holder’s dissenter’s rights, such shares held by such shareholder shall be treated the same as all other holders of LBI Common Stock who at the Effective Time held LBI Common Stock.

1.7CBI Capital Stock. At and after the Effective Time, each share of authorized capital stock of CBI issued and outstanding (“CBI Capital Stock”) immediately prior to the Effective Time shall remain issued and outstanding and shall not be affected by the Share Exchange or Corporate Merger.

1.8Articles of Surviving Corporation and Surviving Bank. At the Effective Time and upon the consummation of the Corporate Merger, the articles of incorporation of CBI, as in effect immediately prior to the Effective Time (the “CBI Articles”), shall be the articles of incorporation of the Surviving Corporation until thereafter amended in accordance with applicable law. At the effective time of the Bank Merger, the charter of association of Catalyst, as in effect immediately prior to the Effective Time, shall be the charter of association of the Surviving Bank (“Catalyst Articles”) until thereafter amended in accordance with applicable law.

#111281803v9

1.9Bylaws of Surviving Corporation and Surviving Bank. At the Effective Time and upon the consummation of the Corporate Merger, the bylaws of CBI, as in effect immediately prior to the Effective Time (the “CBI Bylaws”), shall be the bylaws of the Surviving Corporation until thereafter amended in accordance with applicable law. At the effective time of the Bank Merger, the bylaws of Catalyst, as in effect immediately prior to the Effective Time (“Catalyst Bylaws”), shall be the bylaws of the Surviving Bank until thereafter amended in accordance with applicable law.

1.10Tax Consequences. From and after the date of this Agreement and until the Closing, each party hereto shall use its reasonable best efforts to cause the transactions contemplated by this Agreement to be treated in accordance with the Intended Tax Treatment, and no party shall take any contrary position absent a contrary final determination by a Governmental Entity (within the meaning of Section 1313 of the code or any analogous provision of state or local Tax law).

ARTICLE II.

DELIVERY OF SHARE EXCHANGE CONSIDERATION

2.1Deposit of Share Exchange Consideration. At or prior to the Closing, CBI shall deposit, or shall cause to be deposited, with Catalyst Bank or a reputable third-party exchange agent engaged by Catalyst Bank (the “Exchange Agent”), for the benefit of the holders of shares of LBI Common Stock, for exchange in accordance with this Article II, cash equal to the Share Exchange Consideration (such aggregate cash being hereinafter referred to as the “Exchange Fund”), to be paid pursuant to Section 1.6 in exchange for shares of LBI Common Stock outstanding as of immediately prior to the Effective Time.

2.2Delivery of Share Exchange Consideration.

(a)As soon as practicable, but in no event later than ten (10) business days prior to the Effective Time, CBI shall cause the Exchange Agent to mail to the former record holders of shares of LBI Common Stock issued and outstanding immediately prior to the Effective Time that have been converted into the right to receive a pro-rata portion of the Share Exchange Consideration pursuant to Section 1.6 (other than Dissenting Shares): (i) a letter of transmittal in customary form as reasonably agreed by the parties hereto which shall specify that delivery shall be effected, and risk of loss of and title shall pass, only upon delivery to the Exchange Agent of certificates or other official documentation evidencing such shares of LBI Common Stock (“Certificates,” or “Certificate” in the singular) and (ii) instructions for use in effecting the surrender to the Exchange Agent of Certificates for pro-rata portion of the Share Exchange Consideration due to such holders of shares of LBI Common Stock. Upon proper surrender of a Certificate or Certificates to the Exchange Agent for exchange and cancellation, together with such letter of transmittal duly executed and completed in accordance with the instructions thereto and any other documents reasonably required by the Exchange Agent (“Transmittal Materials”), the holder of such Certificate or Certificates shall be entitled to receive in exchange therefor the pro-rata portion of Share Exchange Consideration that such holder of the Certificates shall have become entitled pursuant to the provisions of Article I and the Certificate or Certificates so surrendered shall forthwith be cancelled. With respect to Certificate(s) and Transmittal Materials received by the Exchange Agent at least five (5) business days before the Effective Time, on the

#111281803v9

Closing Date, and with respect to others, upon the later of (i) the Effective Time and (ii) five (5) business days after receipt by the Exchange Agent, on behalf of CBI, shall deliver the pro-rata portion of Share Exchange Consideration to each such holder in exchange for each such share of LBI Common Stock. No interest will be paid or accrued on the Share Exchange Consideration. Holders of record of shares of LBI Common Stock who hold such shares as nominees, trustees or in other representative capacities may submit multiple letters of transmittal, provided that such representative certifies that each such letter of transmittal covers all the shares of LBI Common Stock held by such representative for a particular beneficial owner. Each Certificate so surrendered and all Transmittal Materials shall be duly completed and endorsed as the Exchange Agent may reasonably require. The Exchange Agent shall not be obligated to deliver the pro-rata portion of the Share Exchange Consideration to which any former holder of shares of LBI Common Stock is entitled as a result of the Share Exchange until such holder surrenders his, her or its Certificate(s) (or affidavits of loss in lieu of such Certificate(s)) for exchange as provided in this Section 2.2. After the Effective Time, each Certificate shall be deemed for all corporate purposes to evidence only the right of the holder thereof to receive a pro-rata portion of the Share Exchange Consideration in exchange for each such share as provided in this Article II.

(b)If any portion of the Share Exchange Consideration is to be paid to someone other than to whom the Certificate or Certificates surrendered in exchange therefor is or are registered, it shall be a condition to such payment that the Certificate or Certificates so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such payment shall first pay to the Exchange Agent in advance any transfer or other Taxes required by reason of such payment to anyone other than the registered holder of the Certificate or Certificates surrendered, or required for any other reason, or shall establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(c)After the Effective Time, there shall be no transfers on the stock transfer books of LBI of the shares of LBI Common Stock that were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for the pro-rata portion of the Share Exchange Consideration due to the record holder or holders of the Certificates at the Effective Time.

(d)Notwithstanding anything to the contrary set forth in this Agreement, Dissenting Shares of LBI Common Stock issued and outstanding immediately prior to the Effective Time and held by a holder who has properly exercised and maintained appraisal rights in respect of such shares in accordance with Part 13 of the LBCA and did not vote for the adoption of this Agreement shall not be converted into a right to receive a pro-rata portion of the Share Exchange Consideration but instead shall be entitled to payment of such consideration as may be determined to be due in accordance with Part 13 of the LBCA; provided, however, that if, after the Effective Time, such holder fails to perfect, withdraws or otherwise loses such holder’s right to appraisal pursuant to Part 13 of the LBCA, or if a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Part 13 of the LBCA, such shares of LBI Common Stock shall be treated as if they had been converted as of the Effective Time into the right to receive a pro-rata portion of the Share Exchange Consideration in accordance with Section 1.6, without interest thereon, upon surrender of such shares of LBI Common Stock. LBI shall give

#111281803v9

prompt notice to CBI of any demands received by LBI for appraisal, of any withdrawals of such demands and of any other instruments served pursuant to the LBCA and received by LBI relating to Part 13 of the LBCA. LBI and CBI shall consult regarding all negotiations and proceedings with respect to such demands, and LBI shall not settle or compromise any such demands without CBI's prior written consent (not to be unreasonably withheld, conditioned or delayed). CBI will pay any holder of Dissenting Shares the payment of such consideration as may be determined to be due in accordance with Part 13 of the LBCA. Prior to the Effective Time, LBI shall not, without the prior written consent of CBI, make any payment with respect to, or settle or compromise or offer to settle or compromise or otherwise negotiate, any such demand, or agree to do any of the foregoing.

(e)Any portion of the Exchange Fund that remains unclaimed by the holders of shares of LBI Common Stock as of the first anniversary of the Effective Time shall be delivered to CBI. Any former holders of shares of LBI Common Stock who have not theretofore complied with this Article II shall thereafter look only to CBI for payment of the Share Exchange Consideration in respect of each share of LBI Common Stock such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of LBI, its Subsidiaries, CBI, Catalyst, the Exchange Agent or any other person shall be liable to any former holder of shares of LBI Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws. Any Share Exchange Consideration remaining unclaimed as of a date which is immediately prior to the time when such amounts would otherwise escheat to or become property of any Governmental Entity shall, to the extent permitted by applicable law, become property of CBI free and clear of any claims or interest of any person or entity otherwise entitled thereto.

(f)In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if, with respect to an individual person, such Certificates represent portions of the Exchange Fund in an aggregate amount equal to or greater than $50,000 and reasonably required by CBI, the posting by such person of a bond in such amount as CBI may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent, or if the Share Exchange Consideration payable with respect to such Certificate has been returned to CBI pursuant to Section 2.2(e), CBI, will issue the related pro-rata portion of the Share Exchange Consideration in exchange for such lost, stolen or destroyed Certificate.

(g)The payment of any income, transfer, documentary, sales, use, stamp, registration, value added and other Taxes and fees (including any penalties and interest) incurred solely by a holder of shares of LBI Common Stock in connection with the Share Exchange or the other transactions contemplated by this Agreement, and the filing of any related return, declaration, report, claim for refund, or information return or statement relating to Taxes, including any schedule or attachment thereto, and including any amendment thereof (each such document, a “Tax Return”) and other documentation with respect to such Taxes and fees, shall be the sole responsibility of such holder.

(h)From and after the Effective Time, the holders of Certificate(s) shall cease to have any rights with respect to the shares of LBI Common Stock represented thereby except as

#111281803v9

provided in this Agreement or by applicable law. All rights to receive the Share Exchange Consideration issued upon conversion of the shares of LBI Common Stock pursuant to this Article II shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of LBI Common Stock.

(i)The Exchange Agent shall invest the cash balances in the Exchange Fund in a demand deposit account or as directed by CBI. Any interest and other income resulting from such investment shall be the sole and exclusive property of CBI and shall be paid to CBI (or the Surviving Corporation) upon termination of the Exchange Fund pursuant to Section 2.2(e).

2.3Bank Merger. At the effective time of the Bank Merger, each share of common stock, $1.00 par value per share, of Lakeside (the “Lakeside Common Stock”) issued and outstanding immediately prior to the effective time of the Bank Merger shall automatically be canceled and there shall be no conversion or exchange of, or consideration paid or issued for, such Lakeside Common Stock. The certificate(s) for such Lakeside Common Stock shall be surrendered and canceled. All of the shares of Catalyst issued and outstanding immediately prior to the effective time of the Bank Merger shall remain issued and outstanding after the effective time of the Bank Merger and shall be unaffected by the Bank Merger.

2.4Withholding. Each of CBI, Catalyst, LBI, Lakeside, the Surviving Corporation and the Surviving Bank is entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of shares of LBI Common Stock such amounts as may be required to be deducted or withheld therefrom under the Code, or any provision of state, local or foreign Tax law or under any other applicable legal requirement. To the extent such amounts are so deducted or withheld and remitted to the appropriate Governmental Entities, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid. The parties hereto shall reasonably cooperate in good faith to reduce or eliminate any such deduction or withholding to the extent permissible under applicable law.

LBI and each of its Subsidiaries have good title to all material assets and properties, whether real or personal, tangible or intangible, reflected in LBI’s consolidated unaudited balance sheet as of December 31, 2025, or acquired subsequent thereto (except for such assets and properties that have been disposed of for fair value in the ordinary course of business since December 31, 2025), free from any Liens except for Permitted Liens.

#111281803v9

any such violation, misappropriation, dilution or infringement.

(b)LBI and Lakeside have in place commercially reasonable data protection and privacy policies and procedures to protect, safeguard and maintain the confidentiality, integrity and security of (i) LBI’s and Lakeside’s information technology systems, Software owned or purported to be owned by LBI and Lakeside (“LBI-Owned Software”), and (ii) all information, data and transactions stored or contained therein or transmitted thereby, including personally identifiable information, financial information, and credit card data (as such information or terms are defined and/or regulated under applicable laws, statutes, orders, rules, regulations, policies, agreements, and guidelines of any Governmental Entity or Regulatory Agency) (the “LBI Data”), against any unauthorized or improper use, access, transmittal, interruption, modification or corruption, except where the failure to have in place such policies and procedures has not had and would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on LBI. LBI and Lakeside are in compliance with applicable confidentiality and data security laws, statutes, orders, rules, regulations, policies, agreements, and guidelines of any Governmental Entity or Regulatory Agency, and all industry standards applicable to the LBI Data, including card association rules and the payment card industry data security standards, except where such failure to be in compliance has not had and would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on LBI. Except as previously disclosed to CBI, to the knowledge of LBI, there currently are not any, and since January 1, 2023, have not been any unauthorized access to or breaches of the security of (i) any of LBI’s and Lakeside’s information technology systems, including the LBI-Owned Software; or (ii) LBI Data or any other such information collected, maintained or stored by or on behalf of LBI and Lakeside (or any unlawful acquisition, use, loss, destruction, compromise or disclosure thereof).

4.21Investment Securities; BOLI.

(a)Each of LBI and its Subsidiaries has good title to all securities and commodities owned by it in all material respects (except those sold under repurchase agreements), free and clear of any Lien (including any restriction, contractual or statutory, that would impair the

#111281803v9

ability of LBI or its Subsidiaries to freely dispose of such investment security at any time), except for investments classified as held to maturity as prescribed under the Financial Accounting Standards Board Accounting Standards Codification 320 and to the extent such securities or commodities are pledged in the ordinary course of business to secure obligations of LBI or its Subsidiaries. Such securities and commodities are valued on the books of LBI in accordance with GAAP in all material respects. LBI and its Subsidiaries and their respective businesses employ investment, securities, commodities, risk management and other policies, practices and procedures that are prudent and reasonable in the context of such businesses. Prior to the date of this Agreement, LBI has made available to CBI the material terms of such policies, practices and procedures.

The value of such BOLI is and has been fairly and accurately reflected in all material respects in the most recent balance sheet included in the financial statements of LBI, in accordance with GAAP. All BOLI is owned solely by LBI, Lakeside or another Subsidiary of LBI, and no other person has any ownership claims with respect to such BOLI or proceeds of insurance derived therefrom and there is no split dollar or similar benefit under such BOLI unless otherwise indicated on Section 4.21(b) of the LBI Disclosure Schedule. Neither LBI nor any of its Subsidiaries has any outstanding borrowings secured in whole or part by its BOLI.

4.22Regulatory Capitalization. LBI is “well-capitalized,” as such term is defined in the rules and regulations promulgated by the FRB. Lakeside is “well-capitalized,” as such term is defined in the rules and regulations promulgated by the OCC.

No material collateral has been released with respect to any LBI Loan unless approved by Lakeside and documented in its files.

its properties, books, contracts, commitments, personnel, information technology systems and records and each shall reasonably cooperate with CBI in preparing to execute after the Effective Time conversion or consolidation of systems and business operations generally (including by entering into customary confidentiality, non-disclosure and similar agreements with such service providers and/or the other party), and, during such period, during normal business hours and in a manner so as not to interfere with normal business operations, each of LBI and Lakeside shall, and shall cause its respective Subsidiaries to, make available to CBI (i) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal securities laws or federal or state banking laws (other than reports or documents which it or any of its Subsidiaries is not permitted to disclose under applicable law) and (ii) all other information concerning its and its Subsidiaries’ business, properties and personnel as CBI may reasonably request. Neither LBI nor any of its respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of LBI’s customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will attempt to obtain waivers or make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b)The Confidentiality Agreement, dated as of January 21, 2026, entered into by and between CBI and LBI (the “Confidentiality Agreement”) will remain in full force and effect following the date of this Agreement, whether or not the Share Exchange, Corporate Merger or Bank Merger occurs, in accordance with the terms thereof, and each of CBI, Catalyst, and LBI and Lakeside shall hold all information furnished by or on behalf of the other party or any of such party’s Subsidiaries or representatives pursuant to this Agreement in confidence to the extent required by, and in accordance with, the provisions of the Confidentiality Agreement.

6.3Requisite Shareholder Approval; LBI Adverse Recommendation Change; Right to Match.

(a)As soon as reasonably practicable, LBI shall take, in accordance with applicable law, the LBI Articles and the LBI Bylaws, all action necessary to duly call, convene and hold a meeting of the shareholders of LBI (including any adjournments, the “LBI Shareholders’ Meeting”). Subject to the remainder of this Section 6.3, LBI and its board of directors shall recommend that LBI’s shareholders approve this Agreement and the transactions contemplated hereby (and shall include such recommendations in the Proxy Statement), and LBI and its board of directors shall otherwise use its reasonable efforts to obtain from the shareholders of LBI the Requisite LBI Approval. Except as expressly permitted by this Section 6.3, and after compliance with this Agreement, neither the board of directors of LBI nor any committee thereof shall (i) withhold, withdraw, amend, modify or qualify (or propose publicly to do any of the foregoing) in a manner adverse in any respect to the interests of CBI, its recommendation that

#111281803v9

LBI’s shareholders approve this Agreement and the transactions contemplated hereby or take any action or make any statement in connection with the LBI Shareholders’ Meeting inconsistent with such recommendation or approval or (ii) approve or recommend (or publicly propose to approve or recommend) any Acquisition Proposal (a “LBI Adverse Recommendation Change”). For purposes hereof, an LBI Adverse Recommendation Change shall include any failure by LBI’s board of directors to recommend against an Acquisition Proposal. Notwithstanding the foregoing or anything to the contrary contained herein, subject to Section 6.10 and Article VIII, at any time prior to, but not after, obtaining the Requisite LBI Approval, if the board of directors of LBI, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisor, determines in good faith that it would be reasonably likely to result in a violation of its fiduciary duties under applicable law to continue to recommend this Agreement, then the board of directors of LBI may modify or qualify its recommendation or effect an LBI Adverse Recommendation Change, and in submitting this Agreement to its shareholders, the board of directors of LBI may submit this Agreement to its shareholders without recommendation or with such modified or qualified recommendation (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), in which event the board of directors of LBI may communicate the basis for its lack of a recommendation or such modified or qualified recommendation to its shareholders in the Proxy Statement or an appropriate amendment or supplement thereto; provided, that LBI and its board of directors may not take any actions under this sentence unless (i) LBI shall have complied in all respects with this Section 6.3 and with Section 6.10 and (ii) the following requirements are met:

(A)LBI gives CBI at least five (5) business days’ prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action (including, in the event such action is taken by the board of directors of LBI in response to an Acquisition Proposal with respect to LBI, the latest material terms and conditions and the identity of the third party in any such Acquisition Proposal, or any amendment or modification thereof, or describe in reasonable detail such other event or circumstances if not in response to an Acquisition Proposal with respect to LBI);

(B)in the event such action is taken by the board of directors of LBI in response to an Acquisition Proposal with respect to LBI, LBI’s board of directors, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisor, determines in good faith that such Acquisition Proposal is a Superior Proposal that has not been withdrawn and continues to be a Superior Proposal after taking into account all adjustments to the terms of this Agreement that may be offered by CBI under this Section 6.3;

(C)during such notice period and any additional notice periods, LBI has negotiated, and has caused its Representatives to negotiate, in good faith with CBI to the extent CBI wishes to negotiate (and nothing herein shall create or imply that CBI has any obligation to so negotiate) to enable CBI to propose revisions to the terms of this Agreement that obviate the need of LBI’s board of directors to effect a LBI Adverse Recommendation Change, including, in the case of a Superior Proposal, by proposing such terms so as to make such Superior Proposal no longer a Superior Proposal; and

(D)at the end of such notice period, the board of directors of LBI takes into account any amendment or modification to this Agreement proposed by CBI and after

#111281803v9

receiving the advice of its outside counsel and, with respect to financial matters, its financial advisor, determines in good faith that the Acquisition Proposal continues to constitute a Superior Proposal and that it would nevertheless be reasonably likely to result in a violation of its fiduciary duties under applicable law to continue to recommend this Agreement.

Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.3 and will require a new notice period as referred to in this Section 6.3; provided, that with respect to any such amendment, the applicable notice period in this Section 6.3 shall be five (5) business days.

(b)LBI shall adjourn or postpone the LBI Shareholders’ Meeting if (i) as of the time for which such meeting is originally scheduled there are insufficient shares of LBI Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or (ii) on the date of such meeting LBI has not received proxies representing a sufficient number of shares necessary to obtain the Requisite LBI Approval; provided, that LBI shall not be required to adjourn or postpone the LBI Shareholders’ Meeting more than one (1) time.

6.4Legal Conditions to Transactions. Subject in all respects to Sections 6.1 and 6.3, LBI and CBI shall, and shall cause their respective Subsidiaries to, use their reasonable best efforts (a) to take, or cause to be taken, all actions reasonably necessary, proper or advisable to comply promptly with all legal requirements that may be imposed on such party or its Subsidiaries with respect to the Share Exchange, the Corporate Merger and the Bank Merger and, subject to the conditions set forth in Article VII hereof, to consummate the transactions contemplated by this Agreement, and (b) to obtain (and to cooperate with the other parties to obtain) any material consent, authorization, order or approval of, or any exemption by, any Governmental Entity or Regulatory Agency without the imposition of any Burdensome Condition and any other third party that is required to be obtained by CBI, LBI or their respective Subsidiaries in connection with the Share Exchange, the Corporate Merger, the Bank Merger and the other transactions contemplated by this Agreement.

6.5Employee Benefit Plans and Employee Matters; Existing Agreements.

(a)CBI and its Subsidiaries shall recognize all services of the employees of LBI, Lakeside and their Subsidiaries who continue to be employed by CBI or a Subsidiary thereof immediately following the Effective Time (“Continuing Employees”) (i) for purposes of eligibility and vesting under each employee benefit plan, program or arrangement established or maintained for employees of CBI or any of its Subsidiaries and (ii) for purposes of benefits accrual under any such plans, program or arrangements that provide for seniority-based severance, paid-time off or vacation pay; provided, however, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits. Such service also shall also be recognized for purposes of satisfying any waiting periods, evidence of insurability requirements, or the application of any preexisting condition limitations. Each benefit plan, program or arrangement of CBI or its Subsidiaries shall waive pre-existing condition limitations to the same extent waived under a corresponding LBI Benefit Plan. To the extent practicable, Continuing Employees shall be given credit for amounts paid under a LBI Benefit Plan for purposes of

#111281803v9

applying deductibles, copayments and out-of-pocket maximums as though such amounts had been paid in accordance with the terms and conditions of the corresponding CBI plan.

(b)CBI hereby acknowledges that a “change in control” (or similar phrase) within the meaning of the LBI Benefit Plans shall occur at the Effective Time.

(c)LBI shall make, or cause its Subsidiaries to make, all contributions due to the Lakeside 401(k) Profit Sharing Plan (the “Lakeside 401(k) Plan”) prior to the Effective Time. After the Effective Time, CBI may, in its discretion and at its option either (i) continue to maintain the Lakeside 401(k) Plan, (ii) merge the Lakeside 401(k) Plan with another tax-qualified plan maintained by CBI or Catalyst, or (iii) terminate the Lakeside 401(k) Plan, unless such termination would result in any Continuing Employee becoming ineligible to immediately participate in any tax-qualified plan maintained by CBI or Catalyst. Alternatively, if requested by CBI prior to the closing, LBI and/or Lakeside shall take all steps necessary to terminate the Lakeside 401(k) Plan prior to the Effective Time including, but not limited to, (i) adopting written resolutions, approved in advance in writing by CBI and its legal counsel, (certified copies of which will be provided to CBI at or before Closing) to terminate the Lakeside 401(k) Plan and fully vest all participants in their benefits thereunder, such termination and vesting to be effective as of the day immediately prior to the Effective Time, (ii) amend the Lakeside 401(k) Plan, as necessary, to accomplish the termination, to bring the Lakeside 401(k) Plan into compliance with all applicable laws including, but not limited to, the Setting Every Community up for Retirement Enhancement Act of 2019 and the Secure 2.0 Act of 2022, effective as to the Lakeside 401(k) Plan, and (iii) delivering, prior to the Closing, notice of the Lakeside 401(k) Plan termination to any trustees and custodians of the Lakeside 401(k) Plan’s assets and to the participants, beneficiaries and any alternative payees under the Lakeside 401(k) Plan. The Continuing Employees who have met the eligibility requirements shall be eligible to participate, effective as of the first business day immediately following the Closing Date, in the Catalyst 401(k) Plan (the “Catalyst 401(k) Plan”). CBI and LBI shall take and/or shall cause their Subsidiaries to take any and all actions as may be required, including amendments to the Lakeside 401(k) Plan and/or Catalyst 401(k) Plan, to permit each Continuing Employee who is a participant in the Lakeside 401(k) Plan and who is employed in a position eligible for participation in the Catalyst Plan and has met the eligibility requirements thereof to be eligible to commence participation in the Catalyst 401(k) Plan as of the first business day immediately following the Closing Date.

(d)Prior to the Effective Time, LBI shall, and shall cause each of its Subsidiaries to, adopt written resolutions, approved in advance in writing by CBI and its legal counsel, (a certified copy of which shall be delivered to CBI prior to or at the Closing) to terminate and liquidate in accordance with Treas. Reg. § 1.409A-3(j)(4)(ix)(B) (i) the provisions of any employment agreement entered into by LBI or its Subsidiaries constituting a “nonqualified deferred compensation plan” within the meaning of Section 409A(d)(1) of the Code, (ii) each LBI Deferred Compensation Plan, and (iii) each other agreement entered into between LBI or a LBI Subsidiary and any employee, director, officer, consultant, independent contractor or other individual which constitutes a nonqualified deferred compensation plan within the meaning of Section 409A(d)(1) of the Code set forth in Section 6.5(d) of the LBI Disclosure Schedule, all such terminations and liquidations to be effective immediately before the Effective Time and intended to be made in full compliance with Section 409A of the Code.

#111281803v9

(e)Nothing in this Agreement shall confer upon any employee, officer, director or consultant of LBI or any of its Subsidiaries or affiliates any right to continue in the employ or service of CBI, the Surviving Corporation, LBI, or any Subsidiary or affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Corporation, LBI, CBI or any Subsidiary or affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of LBI or any of its Subsidiaries or affiliates at any time for any reason whatsoever, with or without cause. Nothing in this Agreement shall be deemed to (i) establish, amend, or modify any LBI Benefit Plan, CBI Benefit Plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of CBI, the Surviving Corporation or any of its Subsidiaries or affiliates to amend, modify or terminate any particular LBI Benefit Plan, CBI Benefit Plan or any other benefit or employment plan, program, agreement or arrangement after the Effective Time. Without limiting the generality of and subject to Section 9.13, nothing in this Agreement, express or implied, is intended to or shall confer upon any person, including any current or former employee, officer, director or consultant of LBI or any of its Subsidiaries or affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. Except as otherwise provided below, Lakeside employees not offered a position with Catalyst, or who are terminated by Catalyst (without cause) within six (6) months following the Effective Time, will receive severance pay at a rate of two (2) weeks’ base pay for each year of service with Lakeside, with a minimum of four (4) weeks of severance pay for each such employee and a maximum of twenty-four (24) weeks of severance pay. Such severance payment will be made in a single lump sum within thirty (30) days after such employee’s general release (and the expiration of any related revocation period) in favor of CBI, Catalyst, LBI, Lakeside, and their respective affiliates, officers, directors and employees becomes effective and irrevocable, provided that the general release must become effective and irrevocable no later than sixty (60) days following such employee’s termination date. If such sixty (60) day period spans two calendar years, the payment will in all events be made in the second calendar year. Notwithstanding the foregoing, no officer or employee of LBI or Lakeside is, or shall be, entitled to receive severance payments that are in addition to payments made under (i) an employment or severance agreement; (ii) a retention or change of control plan or agreement; (iii) this Section 6.5; or (iv) any other similar program or arrangement.

6.6Indemnification; Directors’ and Officers’ Insurance.

(a)In the event of any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, including, without limitation, any such claim, action, suit, proceeding or investigation in which any individual who is now, or has been at any time prior to the date of this Agreement, or who becomes prior to the Effective Time, a director, LLC manager or officer of LBI or any of its Subsidiaries, or who is or was serving at the request of LBI or any of its Subsidiaries as a director, LLC manager, officer or agent of another person (the “Indemnified Parties”), is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that such person is or was a director, LLC manager, or officer of LBI or any of its Subsidiaries or any of their predecessors or is or was serving at the request of LBI or any of its Subsidiaries or any of their predecessors as a director, LLC manager, officer or agent of another person or (ii) this Agreement or any of the transactions contemplated hereby, whether in any case asserted or arising before or after the Effective Time, the parties hereto agree to cooperate and use their best efforts to defend against and respond thereto as provided in this Section 6.6(a). From and after the Effective Time, the Surviving Corporation

#111281803v9

shall indemnify, defend and hold harmless, to the same extent as the Indemnified Parties would have been indemnified under the LBI Articles and LBI Bylaws or any Subsidiary of LBI as such documents were in effect on the date of this Agreement as if the Indemnified Parties were officers or directors of LBI or any such Subsidiary at all relevant times (except that no indemnity shall be provided by CBI hereunder with respect to any claim arising solely and exclusively on account of an Indemnified Party’s service as an officer or director of another for-profit entity that is unrelated to LBI or its Subsidiaries), each such Indemnified Party against any losses, claims, damages, liabilities, costs, expenses (including reasonable attorney’s fees and court costs and expenses in advance of the final disposition of any claim, action, suit, proceeding or investigation to each Indemnified Party upon receipt of an undertaking (in reasonable and customary form) to repay such advances if it is ultimately determined that such Indemnified Party is not entitled to indemnification hereunder), judgments, fines and amounts paid in settlement in connection with any such threatened or actual claim, action, suit, proceeding or investigation. Amounts otherwise required to be paid by CBI to the Indemnified Parties pursuant to this Section 6.6(a) shall be reduced by any amounts that such Indemnified Parties actually recover from any third party, net of all costs and expenses incurred in obtaining such recovery. This indemnity shall be provided for four (4) years following the Effective Time; or if there shall be any proceeding pending or threatened on the third anniversary of the Effective Time, such indemnity shall continue in full force and effect until such pending or threatened proceeding is finally resolved.

(b)LBI, in consultation with CBI, shall obtain at or prior to the Effective Time, a four-year “tail” policy under LBI’s existing directors’ and officers’ and, if applicable, fiduciary liability insurance policy providing the same coverage and amounts, containing terms and conditions which are no less advantageous to the insured with respect to claims against the then-present and former officers and directors of LBI and its Subsidiaries arising from facts or events which occurred at or before the Effective Time.

(c)In the event the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties or assets to any person, then, and in each such case, the Surviving Corporation shall cause proper provision to be made so that the successors and assigns of the Surviving Corporation will expressly assume the obligations set forth in this Section 6.6 in a writing delivered to the Indemnified Parties after the closing of such transaction.

(d)The provisions of this Section 6.6 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives.

6.7Additional Agreements. If at any time after the Effective Time the Surviving Corporation shall consider that any further assignments or assurances in law or any other acts are necessary or desirable to carry out the purposes of this Agreement, LBI and its proper officers and directors shall be deemed to have granted to the Surviving Corporation an irrevocable power of attorney to execute and deliver all such proper deeds, assignments and assurances in law and to do all acts necessary or proper to vest, perfect or confirm title to and possession of such rights, properties and assets in the Surviving Corporation and otherwise to carry out the purposes of this

#111281803v9

Agreement; and the officers and directors of the Surviving Corporation are fully authorized in the name of LBI or otherwise to take any and all such actions after the Effective Time.

6.8Current Information. During the period from the date hereof to the Effective Time, the parties will cause one or more of each of their designated representatives to confer on a monthly or more frequent basis with representatives of the other party regarding each of its business, operations, assets, liabilities, condition (financial or otherwise), results of operations or matters relating to the completion of the transactions contemplated hereby. Without limiting the generality of the foregoing, (i) in such conferences with representatives of CBI the designated representative(s) of LBI and Lakeside shall provide updates with respect to loan charge-offs and sales of other real estate owned and the status of any efforts to sell any Special Asset since the last conference, (ii) within ten (10) days after the end of each calendar month, LBI shall provide CBI with (A) an unaudited consolidated balance sheet as of the end of such month, together with unaudited consolidated statements of income, shareholders’ equity and cash flows for the month and year-to-date period, which unaudited consolidated financial statements will be prepared in accordance with GAAP and will fairly present, in all material respects, the financial position of LBI at the respective dates thereof and the results of LBI’s operations and cash flows for the periods indicated therein, subject to the omission of footnotes and normal and year-end audit adjustments as permitted by GAAP so long as none of which adjustments, to the extent they relate to LBI’s or Lakeside’s capital ratios, will be material, and (B) a schedule of loans charged-off during such month and other real estate owned sold during such month. Within five (5) business days after filing, each party shall provide the other party a copy of all reports, forms, correspondence, registrations and statements, together with any amendments thereto, that the party files during the period from the date of this Agreement to the Effective Time with the Louisiana Secretary, the OCC, the OFI, the FRB and any other federal or state Governmental Entity having jurisdiction over that party, other than any portions of material filed that contain confidential supervisory information or other information filed under a claim of confidentiality and, in each case, subject to applicable laws relating to the exchange of information. Each party acknowledges and agrees that nothing in this Agreement, including this Section 6.8, shall require any party to provide confidential supervisory information to any other party.

6.9Advice of Changes. LBI and CBI shall promptly advise the other of any fact, change, event or circumstance known to it (i) that has had or is reasonably likely to have a Material Adverse Effect on it or (ii) which it believes would or would be reasonably likely to cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein or that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article VII; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under this Agreement; provided, further, that a failure to comply with this Section 6.9 shall not constitute the failure of any condition set forth in Sections 7.2 or 7.3 to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case unless the underlying breach would independently result in the failure of a condition set forth in Sections 7.2 or 7.3 to be satisfied.

6.10Non-Solicitation; Acquisition Proposals.

#111281803v9

(a)Upon the execution of this Agreement, LBI shall, and shall cause its Subsidiaries, affiliates, directors, officers, employees, agents and representatives (including any investment banker, financial advisor, attorney, accountant or other representative retained by LBI or any of its affiliates (each a “Representative”), to immediately cease and terminate any and all existing discussions, negotiations or activities with any other parties conducted heretofore (whether currently ongoing or not) with respect to the possibility or consideration of any Acquisition Proposal. Upon the request by CBI, LBI shall request the return and/or destruction (at the recipient’s option) of all confidential information provided to any such person. Except as otherwise provided in Section 6.10(b), from the date of this Agreement through the Effective Time, LBI shall not, shall cause each of its Subsidiaries not to, and shall not authorize or permit any of its Representatives to, directly or indirectly, (i) solicit, initiate, knowingly facilitate or knowingly encourage (including by way of furnishing information or assistance), or take any other action designed to solicit, initiate, knowingly facilitate or encourage any inquiries or the making of any proposal that constitutes, or is reasonably likely to lead to, any Acquisition Proposal with respect to LBI, (ii) participate in any discussions, negotiations or other communications regarding any Acquisition Proposal with respect to LBI, (iii) except pursuant to Section 6.3 in connection with making a LBI Adverse Recommendation Change, make or authorize any statement, recommendation or solicitation in support of any Acquisition Proposal with respect to LBI, or (iv) provide any confidential or nonpublic information or data to any person relating to an Acquisition Proposal with respect to LBI. LBI agrees that it will take the necessary steps to inform its Representatives of the obligations undertaken in this Section 6.10.

(b)

(i)Notwithstanding the foregoing Section 6.10(a), but subject to compliance with Section 6.3 and this Section 6.10, prior to the receipt the Requisite LBI Approval (but not after), LBI may and may permit its Subsidiaries and its Subsidiaries’ Representatives to engage in discussions and negotiations with, or provide any nonpublic information or data to, any person in response to an unsolicited bona fide written Acquisition Proposal with respect to LBI by such person (that did not result from a breach of this Section 6.10) made after the date of this Agreement to the extent that (x) LBI’s board of directors determines in good faith that the Acquisition Proposal constitutes or is reasonably likely to result in a Superior Proposal and (y) LBI’s board of directors determines in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its financial advisors) that failure to take such actions would be reasonably likely to result in a violation of its fiduciary duties under applicable law; provided, however, that, prior to providing any nonpublic information permitted to be provided pursuant to the foregoing, LBI shall have provided notice to CBI of its intention to provide such information, and shall have provided such information to CBI, and shall have entered into a confidentiality agreement with such third party on terms no less favorable to it than the Confidentiality Agreement, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with such party or prohibit disclosure to CBI of the terms and conditions of any Acquisition Proposal.

(ii)LBI shall promptly (but in no event later than forty-eight (48) hours) notify CBI after receipt of any Acquisition Proposal, any request for nonpublic information relating to LBI or any of its Subsidiaries that would reasonably be expected to lead to an Acquisition Proposal, or any inquiry from any person seeking to have discussions, negotiations or

#111281803v9

other communications relating to a possible Acquisition Proposal. Such notice shall, if made orally, be confirmed in writing, and shall indicate the identity of the person making the Acquisition Proposal, inquiry or request and the material terms and conditions of any inquiries, requests, proposals or offers (including a copy thereof if in writing and any related documentation or correspondence). LBI shall also promptly, and in any event within twenty-four (24) hours, notify CBI if it enters into discussions or negotiations or engages in other communications concerning any Acquisition Proposal or provides nonpublic information or data to any person in accordance with this Section 6.10(b) and keep CBI informed of the status and terms of any such proposals, offers, discussions or negotiations on a reasonably current basis in the event of any material changes in the status or terms of any such proposal, offer, discussion or negotiation, including by providing a copy of all material documentation or correspondence relating thereto. If LBI elects to make an LBI Adverse Recommendation Change, then LBI shall comply with Section 6.3(a). LBI shall not release any third party from or waive any provisions of, and shall use its reasonable best efforts to enforce, any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party as of the date hereof in accordance with the terms thereof.

(c)Unless this Agreement has been terminated in accordance with its terms, LBI shall not, and shall cause its Subsidiaries and use its reasonable best efforts to cause its and their officers, directors, managers, agents, advisors and Representatives not to on its or any of its Subsidiaries’ or affiliates’ behalf, enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, or other agreement (other than a confidentiality agreement referred to and entered into in accordance with Section 6.10(b)) relating to any Acquisition Proposal.

(d)For purposes of this Agreement, the term “Acquisition Proposal” means any proposal, offer, third party indication of interest, inquiry, filing of any regulatory application or notice (whether in draft or final form) or disclosure of an intention to do any of the foregoing from any third party relating to any (x) direct or indirect acquisition or purchase of more than 20% of the consolidated assets of LBI or more than 20% of any class of equity or voting securities of LBI, or any of LBI’s Subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of LBI, (y) tender offer (including a self-tender) or exchange offer that, if consummated, would result in such third party beneficially owning more than 20% of any class of equity or voting securities of LBI, or any of LBI’s Subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of LBI or (z) merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or similar transaction involving LBI or any of its Subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of LBI (other than, in the case of this clause (z) any such transaction pursuant to which the shareholders of LBI immediately preceding such transaction would continue to hold 80% or more of the equity or voting interests in the surviving or resulting entity of such transaction (or, if applicable, the ultimate parent thereof)), in each case other than the transactions contemplated by this Agreement. For purposes of this Agreement, the term “Superior Proposal” means an unsolicited bona fide written Acquisition Proposal that is received by LBI and that LBI’s board of directors, respectively, concludes in good faith, after consultation with its outside legal counsel and financial advisor, taking into account all legal, financial, regulatory and other aspects of such Acquisition Proposal and the person making such Acquisition Proposal (including any applicable termination fees, expense reimbursement provisions and conditions to consummation) that LBI’s board of

#111281803v9

directors deems relevant as well as the terms and conditions of this Agreement (as it may be proposed to be amended by CBI), is (i) more favorable to the shareholders of LBI from a financial point of view than the transactions contemplated by this Agreement, and (ii) reasonably capable of being completed on the terms proposed; provided that, for purposes of this definition of Superior Proposal, the term Acquisition Proposal shall have the meaning assigned to such term in the paragraph immediately above except that the reference to “20% or more” in the definition of Acquisition Proposal shall be deemed to be a reference to “50% or more.”

6.11No Control of Other Party’s Business. Nothing contained in this Agreement shall give CBI, directly or indirectly, the right to control or direct the operations of LBI or its Subsidiaries prior to the Effective Time, and nothing contained in this Agreement shall give LBI, directly or indirectly, the right to control or direct the operations of CBI or its Subsidiaries prior to the Effective Time. Prior to the Effective Time, each of CBI and LBI shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations. Subject to the foregoing, LBI and Lakeside shall cooperate with CBI and Catalyst in connection with planning for the efficient and orderly combination of the parties and the operation of the Surviving Bank after the Bank Merger, and in preparing for the consolidation of appropriate operating functions to be effective on the Closing Date or such later date as CBI may decide. LBI shall take, and shall use its commercially reasonable efforts to cause its data processing consultants and software providers to take, any action CBI may reasonably request prior to the Effective Time to facilitate the combination of the operations of Lakeside with Catalyst. Without limiting the foregoing, LBI shall provide office space and support services (and other reasonably requested support and assistance) in connection with the foregoing, but only to the extent the provision of such services does not unreasonably interfere with the normal operations of LBI.

6.12Adoption of Accounting Policies. As soon as practicable after the satisfaction or waiver of all conditions to the Closing set forth in Article VII and at such time as consummation of the transactions contemplated by this Agreement seems reasonably assured and in any event prior to the Effective Time (unless this Agreement is terminated pursuant to Article VIII), LBI and Lakeside shall take any and all necessary or appropriate actions to adopt all CBI accounting procedures and policies (including those policies pertaining to charged-off and non-accrual assets); provided, however, that no such action taken by LBI or Lakeside at the request of CBI pursuant to this section shall be deemed to be, or be deemed to cause, a breach of any representation or warranty made by LBI or Lakeside herein.

6.13Change of Method. Notwithstanding anything to the contrary contained in this Agreement, before the Effective Time, CBI may at any time change the method of effecting the business combination contemplated by this Agreement if and to the extent that it deems such a change to be necessary, appropriate or desirable; provided, however, that no such change shall (i) alter or change the amount or kind of Share Exchange Consideration received by holders of shares of LBI Common Stock, (ii) adversely affect the federal income tax consequences of the Share Exchange, the Corporate Merger or the Bank Merger to (A) holders of shares of LBI Common Stock as a result of receiving the Share Exchange Consideration or (B) CBI or holders of CBI Common Stock or (iii) materially impede or delay consummation of the transactions contemplated by this Agreement in a timely manner. In the event CBI elects to make such a change, the parties agree to execute appropriate documents to reflect the change.

#111281803v9

6.14Takeover Statutes. None of CBI, LBI or their respective boards of directors shall take any action that would cause any Takeover Statute to become applicable to this Agreement, the Share Exchange, the Corporate Merger, the Bank Merger or any of the other transactions contemplated hereby, and each shall take all necessary steps to exempt (or ensure the continued exemption of) the Share Exchange, the Corporate Merger, the Bank Merger and the other transactions contemplated hereby from any applicable Takeover Statute now or hereafter in effect. If any Takeover Statute may become, or may purport to be, applicable to the transactions contemplated hereby, each party and the members of their respective boards of directors will grant such approvals and take such actions as are necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any Takeover Statute on any of the transactions contemplated by this Agreement, including, if necessary, challenging the validity or applicability of any such Takeover Statute.

6.15Shareholder Litigation. LBI shall provide CBI the opportunity to participate in the defense or settlement of any shareholder litigation against LBI and/or its directors relating to the transactions contemplated by this Agreement throughout the course of any such litigation, and CBI shall in good faith consider the recommendations of LBI regarding such litigation. LBI shall not settle any shareholder litigation without CBI’s prior written consent (such consent not to be unreasonably withheld or delayed).

6.16Officer Agreements. Both CBI and LBI shall take such actions as are reasonably necessary to terminate, effective immediately prior to the Effective Time, any agreements between LBI and/or Lakeside and their respective executives, each of which are set forth in Section 6.16 of the LBI Disclosure Schedules. The termination and liquidation of such agreements shall be made consistent with the provisions of Section 409A of the Code for termination and liquidation of a plan in connection with a change in control event under Section 409A of the Code, so as to avoid any additional tax, interest or penalties in connection with the termination and liquidation of such agreements.

6.17Section 280G Matters. Concurrent with the execution of this Agreement and as a condition thereof, Roy M. Raftery, Jr., shall execute an amendment to his existing Change in Control Agreement dated June 21, 2021, in the form attached to this Agreement as Exhibit E so that (i) LBI and it’s successors will not be responsible for any “Gross-Up Payment” related to an excise tax imposed by Section 4999 of the Code, and (ii) the payment he receives in satisfaction of the obligations of LBI and Lakeside thereunder will be reduced to the maximum amount that can be paid without triggering or resulting in any payment, including, without limitation, any “excess parachute payment” as defined in Section 280G of the Code, that could be disallowed as a deduction or result in the payment of excise taxes under Section 280G or 162(m) of the Code. Notwithstanding the foregoing, prior to the Closing Date, LBI and CBI shall work together in good faith to implement mutually satisfactory arrangements such that the Share Exchange will not trigger or result in any payment, including, without limitation, any “excess parachute payment” as defined in Section 280G of the Code, that could be disallowed as a deduction or result in the payment of excise taxes under Section 280G or 162(m) of the Code, including but not limited to relying on a report of an independent valuation appraiser that all or any portion of such payments or benefits constitute “reasonable compensation” as described in Treasury Regulations Section 1.280G-1, Q&A 42 or conducting a vote of LBI shareholders to approve any such payment (a

#111281803v9

“280G Remedy”). Any 280G Remedy shall be subject to CBI’s review and approval with such approval not to be unreasonably withheld.

TERMINATION AND AMENDMENT

8.1Termination. This Agreement may be terminated at any time prior to the Effective Time, whether before or after approval of this Agreement by the shareholders of LBI:

(a)by mutual consent of CBI and LBI in a written instrument, if the board of directors of each so determines;

(b)by either CBI (on behalf of itself and Catalyst) or LBI (on behalf of itself and Lakeside) (i) twenty (20) or more days after the date upon which any application for a Requisite

#111281803v9

Regulatory Approval has been denied or withdrawn at the request of the applicable Governmental Entity or Regulatory Agency, unless within such 20-day period a petition for rehearing or an amended application is filed or noticed, or (ii) twenty (20) or more days after any petition for rehearing or amended application filed pursuant to clause (i) is denied; provided, however, that no party hereto shall have the right to terminate this Agreement pursuant to Section 8.1(b)(i) or Section 8.1(b)(ii) if such denial or request or recommendation for withdrawal shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements of such party set forth in this Agreement; and in each case the time period for appeals and requests for reconsideration has run, or (iii) if any Governmental Entity or Regulatory Agency that must grant a Requisite Regulatory Approval has denied approval of the Share Exchange, the Corporate Merger or the Bank Merger and such denial has become final and nonappealable or any Governmental Entity or Regulatory Agency of competent jurisdiction shall have issued a final nonappealable order, injunction or decree permanently enjoining or otherwise prohibiting or making illegal the consummation of the Share Exchange, the Corporate Merger or the Bank Merger, unless the failure to obtain a Requisite Regulatory Approval shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements of such party set forth herein;

(c)by either CBI (on behalf of itself and Catalyst) or LBI (on behalf of itself and Lakeside) if (i) the Share Exchange shall not have been consummated on or before December 31, 2026 (the “Termination Date”), unless any Requisite Regulatory Approval is pending and has not been finally resolved, in which event such date shall be automatically extended to March 31, 2027, or (ii) if a vote of the shareholders of LBI is taken and LBI fails to obtain the Requisite LBI Approval; provided, that the failure of the Closing to occur by such date or the failure to obtain the Requisite LBI Approval shall not be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements of such party set forth herein;

(d)by either CBI (on behalf of itself and Catalyst) or LBI (on behalf of itself and Lakeside) (provided, that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein) if there shall have been a breach of any of the covenants or agreements or any of the representations or warranties (or any such representation or warranty shall cease to be true) set forth in this Agreement on the part of LBI, in the case of a termination by CBI, or CBI, in the case of a termination by LBI, which breach or failure to be true, either individually or in the aggregate with all other breaches by such party (or failures of such representations or warranties to be true), would constitute, if occurring or continuing on the Closing Date, the failure of a condition set forth in Section 7.2, in the case of a termination by LBI, or Section 7.3, in the case of a termination by CBI, and which is not cured by the earlier of the Termination Date and thirty (30) days following written notice to LBI, in the case of a termination by CBI, or CBI, in the case of a termination by LBI, or by its nature or timing cannot be cured during such period;

(e)by CBI (on behalf of itself and Catalyst), if (i) prior to such time as the Requisite LBI Approval is obtained, LBI or its board of directors (A) makes a LBI Adverse Recommendation Change (or publicly discloses its intention to do so) or otherwise submits this Agreement to its shareholders without a recommendation for approval, or recommends (or publicly discloses its intention to do so) to its shareholders an Acquisition Proposal other than the Share Exchange or if LBI, its Subsidiaries or its Representatives otherwise breaches, in any material

#111281803v9

respect, its obligations under Section 6.10 of this Agreement, or (B) materially breaches its obligations under Section 6.3 or Section 6.10, or (ii) a tender offer or exchange offer for more than 20% of the outstanding shares of LBI Common Stock is commenced (other than by CBI or a Subsidiary thereof), and the board of directors of LBI recommends that the shareholders of LBI tender their shares in such tender offer or exchange offer or otherwise fails to recommend that such shareholders reject such tender offer or exchange offer within the ten (10) business day period specified in Rule 14e-2(a) under the Exchange Act;

(f)by CBI (on behalf of itself and Catalyst), if holders of more than 5% of the shares of LBI Common Stock outstanding at any time prior to the Closing Date exercise their dissenters rights pursuant to Chapter 23 of the LBCA; or

(g)by LBI (on behalf of itself and Lakeside), at any time prior to the receipt of the Requisite LBI Approval, for the purpose of entering into a definitive agreement with respect to a Superior Proposal, provided, that LBI and its Subsidiaries and Representatives have not breached any of their obligations under Sections 6.3 or 6.10 of this Agreement; and, provided, further, that any such purported termination pursuant to this Section 8.1(g) shall be void and of no force or effect unless LBI has paid the Termination Fee in accordance with Section 8.3.

The party desiring to terminate this Agreement pursuant to clause (b), (c), (d), (e), (f), (g), or (h) of this Section 8.1 shall give written notice of such termination to the other party in accordance with Section 9.4, specifying the provision or provisions hereof pursuant to which such termination is effected.

8.2Effect of Termination. In the event of termination of this Agreement by either CBI or LBI as provided in Section 8.1, this Agreement shall forthwith become void and have no effect, and none of CBI, LBI, any of their respective Subsidiaries or any of the officers or directors of any of them shall have any liability of any nature whatsoever hereunder, or in connection with the transactions contemplated hereby, except that (i) Section 6.2(b), this Section 8.2, Section 8.3 and Article IX (other than Section 9.1) shall survive any termination of this Agreement, and (ii) notwithstanding anything to the contrary contained in this Agreement, neither CBI nor LBI shall be relieved or released from any liabilities or damages (which, in the case of LBI, shall include the loss to the holders of LBI Common Stock of the economic benefits of the transactions contemplated hereby, including the loss of the premium offered to the holders of LBI Common Stock, it being understood that LBI shall be entitled to pursue damages for such losses and to enforce the right to recover such losses on behalf of its shareholders in its sole and absolute discretion, and any amounts received by LBI in connection therewith may be retained by LBI) arising out of its fraud or willful and material breach of any provision of this Agreement.

8.3Termination Fee.

(a)In the event that after the date of this Agreement and prior to the termination of this Agreement a non-solicited bona fide Acquisition Proposal with respect to LBI shall have been made known to senior management of LBI or shall have been made directly to its shareholders generally or any person reasonably qualified to consummate an Acquisition Proposal shall have publicly announced (and not irrevocably withdrawn at least five (5) business days prior to the LBI Shareholders’ Meeting) an Acquisition Proposal with respect to LBI and (x) thereafter

#111281803v9

(A) this Agreement is terminated by either CBI or LBI pursuant to Section 8.1(c) without the Requisite LBI Approval having been obtained, (B) this Agreement is terminated by CBI pursuant to Sections 8.1(e), or (C) this Agreement is terminated by LBI pursuant to Section 8.1(g) and (y) prior to the date that is twelve (12) months after the date of such termination, LBI enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal with respect to LBI (whether or not the same Acquisition Proposal as that referred to above), then LBI shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay CBI, by wire transfer of same day funds, a fee equal to $1,650,000 (the “Termination Fee”); provided, that for purposes of this Section 8.3, all references in the definition of Acquisition Proposal to “20%” shall instead refer to “50%.”

(b)In the event this Agreement is terminated by CBI pursuant to Section 8.1(e) or by LBI pursuant to Section 8.1(g), then concurrently with such termination if terminated by LBI, or within two (2) business days after termination if terminated by CBI, LBI shall pay CBI, by wire transfer of same day funds, the Termination Fee, and such termination shall not be deemed effective hereunder until payment by the terminating party of such fee.

(c)Notwithstanding anything to the contrary herein, but without limiting the right of any party to recover liabilities or damages in accordance with Section 8.2, the maximum aggregate amount of fees payable by LBI under this Section 8.3 shall be equal to the Termination Fee, and in no event shall LBI be required to pay the Termination Fee more than once.

(d)Each party acknowledges that the agreements contained in this Section 8.3 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, CBI would not enter into this Agreement; accordingly, if LBI fails to pay promptly the Termination Fee pursuant to this Section 8.3 and, in order to obtain such payment, CBI commences a suit which results in a judgment against LBI for the fee set forth in this Section 8.3, LBI shall pay CBI its costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of the fee at a rate per annum equal to the effective federal funds rate on the date such payment was required to be made.

(e)The parties agree that the payment of the Termination Fee shall be the sole and exclusive remedy available to CBI and Catalyst with respect to this Agreement in the event any such payment becomes due and payable and is paid, and, upon payment of the Termination Fee, LBI and Lakeside (and LBI’s and Lakeside’s affiliates and its and their respective directors, officers, employees, shareholders and representatives) shall have no further liability to CBI and Catalyst under this Agreement; provided, however, that LBI and Lakeside shall not be relieved or released from any liabilities or damages arising out of their willful and material breach of this Agreement; provided, further, that the aggregate amount of any damages determined by a court to be payable by LBI and Lakeside pursuant to the foregoing proviso shall be reduced by the amount of any Termination Fee previously paid to CBI pursuant to this Section 8.3.

9.5Interpretation. The parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement. When a reference is made in this Agreement to Articles, Sections, Exhibits or Schedules, such reference shall be to an Article or Section of or Exhibit or Schedule to this Agreement, unless otherwise indicated. The LBI Disclosure Schedule and each other Exhibit and Schedule hereto shall be deemed part of this Agreement and included in any reference to this Agreement. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” References to “the date hereof” shall mean the date of this Agreement. Whenever the singular or plural form of any word is used in this Agreement, such word shall encompass both the singular and plural form of such word. All references to any period of days shall be deemed to be the relevant number of calendar days unless otherwise specified. As used in this Agreement, (i) the “knowledge” of LBI means the actual knowledge of the senior executive officers of LBI and Lakeside (i.e., the executive vice president level and above) and all facts of which any such person or persons would reasonably be expected to know in the normal course of exercising his or her duties based on applicable title or position, and the “knowledge” of CBI means the actual knowledge of the senior executive officers of CBI and Catalyst (i.e., the senior executive vice president level and above) and all facts of which any such person or persons would reasonably be expected to know in the normal course of exercising his or her duties based on applicable title or position; (ii) “business day” means any day other than a Saturday, a Sunday or a day on which banks in Opelousas, Louisiana, are closed as authorized by law or executive order; (iii) the term “person” means any individual, corporation (including not-for-profit), general or limited partnership, limited liability company, joint venture, estate, trust, association, organization, Governmental Entity or other entity of any kind or nature; and (iv) an “affiliate” of a specified person is any person that directly or indirectly controls, is controlled by, or is under common control with, such specified person. Any document or item will be deemed “delivered,” “provided” or “made available” to a party within the meaning of this Agreement if such document or item is (i) made available to such party specifically for review in person by the other party or its representatives, (ii) contained and accessible to such party for a continuous period of at least four (4) days immediately prior to the execution of this Agreement (if to be delivered, provided or made available prior to the date hereof) or the Closing Date (if to be delivered, provided or made available prior to Closing) in the electronic data room established in connection with the transactions contemplated hereby to which CBI and its designated representatives had access rights during such period, or (iii) filed by CBI with the SEC and publicly available on EDGAR at least forty-eight (48) hours immediately prior to the execution of this Agreement (if to be delivered, provided or made available prior to the date hereof) or the Closing Date (if to be delivered, provided or made available prior to Closing). All references to “dollars” or “$” in this Agreement are to United States dollars.

The parties intend that each representation, warranty and covenant contained herein shall have independent significance. If any party has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or

#111281803v9

covenant relating to the same subject matter (regardless of the relative levels of specificity) that the party has not breached shall not detract from or mitigate the fact that the party is in breach of the first representation, warranty or covenant. Further, it is understood and agreed that the specification of any dollar amount in the representations and warranties contained in this Agreement or the inclusion of any specific item in the LBI Disclosure Schedule is not intended to imply that such amounts or higher or lower amounts, or the items so included or other items, are or are not material or would have a Material Adverse Effect on LBI or CBI, as the case may be, and neither party shall use the fact of the setting of such amounts or the fact of the inclusion of any such item in the LBI Disclosure Schedule in any dispute or controversy between the parties as to whether any obligation, item or matter not described in this Agreement or included in the LBI Disclosure Schedule is or is not material for purposes of this Agreement.

9.6Amendment. Subject to compliance with applicable law, this Agreement may be amended by the parties hereto at any time prior to the Effective Time, whether before or after the approval of the transactions contemplated by this Agreement by the shareholders of LBI; provided, however, that after any approval of the transactions contemplated by this Agreement by the shareholders of LBI, there may not be, without further approval of such shareholders, any amendment of this Agreement that (i) reduces the amount or changes the form of consideration to be received by LBI shareholders, (ii) materially adversely affects the rights of LBI shareholders, or (iii) otherwise requires further approval under applicable law. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

9.7Extension; Waiver.

Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

9.8Counterparts. This Agreement may be executed in counterparts, all of which shall be considered one and the same agreement, and shall become effective when counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart.

9.9Entire Agreement. This Agreement (including the documents and the instruments referred to herein and all schedules, exhibits, and disclosure schedules attached hereto or delivered in connection herewith) together with the Confidentiality Agreement, the Share Exchange Agreement, the Corporate Merger Agreement and the Bank Merger Agreement constitute the

By execution and delivery of this Agreement, the parties hereby accept for themselves, and in respect of their property, generally and unconditionally, the jurisdiction and venue of the aforesaid courts and waive any objection to the laying of venue on the grounds of a lack of jurisdiction or forum non conveniens which they may now or hereafter have to the bringing or maintaining of any such action or proceeding in such jurisdiction, and agree that service of process upon any party in any such action or proceeding will be effective if notice is given in accordance with Section 9.4.

9.11Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY ACKNOWLEDGES THAT IT HAS HAD THE OPPORTUNITY TO CONSULT WITH COUNSEL REGARDING THIS JURY TRIAL WAIVER AND THAT THIS WAIVER IS A MATERIAL INDUCEMENT FOR THE OTHER PARTIES TO ENTER INTO THIS AGREEMENT.

Notwithstanding the foregoing, LBI and CBI shall each cooperate fully in disclosing and providing all information required for public disclosure of this Agreement or the

#111281803v9

transactions contemplated hereby in accordance with applicable securities laws or the rules of OTCQX or NASDAQ.

9.13Assignment; Third Party Beneficiaries. Neither this Agreement nor any of the rights, interests or obligations of the parties hereto shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other parties hereto. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns. Any purported assignment in contravention hereof shall be null and void. Except for (i) as otherwise specifically provided in Section 6.5, (ii) the rights of Indemnified Parties under Section 6.6, and (iii) from and after the Effective Time, but only if the Effective Time shall occur, the rights of holders of shares of LBI Common Stock to receive the Share Exchange Consideration as provided in Article II, this Agreement (including the documents and instruments referred to herein) is not intended to confer upon any person other than the parties hereto any rights or remedies hereunder. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance herewith without notice or liability to any other person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, persons other than the parties hereto may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

9.14Severability. Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or portion of any provision in such jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction such that the invalid, illegal or unenforceable provision or portion thereof shall be interpreted to be only so broad as is enforceable.

9.15Delivery by Facsimile or Electronic Transmission. This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments or waivers hereto or thereto, to the extent signed and delivered by means of a facsimile machine or by e-mail delivery of a “.pdf” format data file, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine or e-mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment or waiver hereto or other such instrument or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense to the formation of a contract, and each party hereto forever waives any such defense.

Form of Shareholder Support Agreement

The undersigned shareholder of Lakeside Bancshares, Inc. (“LBI”), in consideration of the benefits to be derived by LBI and its shareholders and the undersigned shareholder pursuant to an Agreement and Plan of Share Exchange and Merger dated April 7, 2026 (the “Agreement”) by and between LBI, Catalyst Bancorp, Inc. (“Corporation”), Lakeside Bank (“Lakeside”), and Catalyst Bank (“Catalyst”) (the defined terms in which are used herein as defined therein) and the expenses to be incurred by Corporation and Catalyst in connection therewith, hereby agrees with Corporation as follows:

1.Such shareholder, acting solely in such shareholder’s capacity as such, agrees and undertakes to vote or cause to be voted all shares of LBI Common Stock as to which such shareholder has voting power at any meeting or meetings (including any and all adjournments thereof) before which the Agreement or any similar agreement may come for consideration by LBI shareholders, in favor of the approval of the Agreement, the Share Exchange Agreement, the Corporate Merger Agreement, and the Bank Merger Agreement, and against any similar agreement, unless Corporation or Catalyst is then in breach or default in any material respect with respect to any covenant, representation or warranty as to them contained in the Agreement to an extent that would permit LBI and Lakeside to terminate the Agreement pursuant to Section 8.1(d) of the Agreement. Such shareholder further agrees not to transfer any of the shares of LBI Common Stock over which such shareholder has dispositive power or grant any proxy thereto (except any such proxy approved by Corporation) until the earlier of the Effective Time or the date that the Agreement has been terminated pursuant to its provisions, except (i) for transfers by operation of law, (ii) for transfers to immediate family members or trusts for the benefit of the shareholder or immediate family members, and (iii) for transfers in connection with which the transferee shall agree in writing with Corporation to be bound by this Shareholder Support Agreement as fully as the undersigned. In the case of any transfer described in (i) or (ii), the provisions of this Shareholder Support Agreement are intended to be binding upon and to inure to the benefit of such transferee, and such transferee shall be bound thereby.

2.The provisions of this Shareholder Support Agreement shall be enforceable through an action by Corporation for damages at law or a suit for specific performance or other appropriate equitable relief, the signatory shareholder acknowledging that remedies at law for breach or default under this Shareholder Support Agreement are inadequate. Notwithstanding the foregoing, the shareholder shall have the right to contest the adequacy of legal remedies and Corporation's entitlement to equitable relief.

All provisions hereof shall survive the Effective Time of the Share Exchange and well as the effective times of the Corporate Merger and the Bank Merger.

AMENDMENT TO

CHANGE IN CONTROL AGREEMENT

THIS AMENDMENT TO CHANGE IN CONTROL AGREEMENT (“Amendment”) is made as of April __, 2026, by and among LAKESIDE BANK, a Louisiana state-chartered bank ("Bank" or “Company”), and Roy M. Raftery, jr. (the “Employee”), a resident of the State of Louisiana.

W I T N E S S E T H:

WHEREAS, the Employee currently serves as the President and CEO of Lakeside Bancshares, Inc., a Louisiana Corporation (“Corporation”) and its wholly owned subsidiary, Bank; and

WHEREAS, Corporation and Catalyst Bancorp, Inc., a Louisiana Corporation (“CBI”), and their respective subsidiaries, Bank and Catalyst Bank, a federal savings association that has elected to be treated as a covered savings association under Section 5 of the Home Owners’ Loan Act (“Catalyst”) are parties to an Agreement and Plan of Share Exchange and Merger, dated simultaneously herewith (the “Definitive Agreement”), whereby CBI will acquire Corporation (and thus indirectly Bank) and Corporation and Bank will be merged with and into CBI and Catalyst and, thereafter, CBI and Catalyst will continue to operate the business formerly conducted by Corporation and Bank; and

WHEREAS, as a condition of and inducement to CBI and Catalyst entering into the Definitive Agreement, the Employee has agreed to enter into this Amendment to Employee’s existing Change in Control Agreement with Bank dated June 21, 2021 (“CIC Agreement”); and

NOW, THEREFORE, in consideration of the provisions of the Definitive Agreement and this Amendment, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Bank and the Employee agree as follows:

1.Removal of Certain Additional Payments by Bank. Section 2 of the CIC Agreement shall be deleted in its entirety.

2.Net Payment/Cut-Back. Section 4 of the CIC Agreement shall be deleted in its entirety and replaced with the following language:

“The parties intend that the payments provided for herein are reasonable compensation for the Employee's services to the Company and shall not constitute ‘parachute payments’ within the meaning of Section 280G of the Internal Revenue Code (the “Code”) and any regulations thereunder. Notwithstanding any other provision of this Agreement, if any payment or benefit to be paid or provided to Employee, whether pursuant to this Agreement or otherwise, would constitute a ‘parachute payment’ within the meaning of Section 280G of the Code, such payments and benefits shall be reduced to an amount, the aggregate value of which is $1.00 less than an amount equal to three (3) times the Employee’s ‘base amount,’

E-2

#111281803v9

as determined in accordance with Section 280G of the Code. The reduction shall be made from the amount of the payment under this Agreement.”

3.Taxes. Employee acknowledges and agrees that the cut-back gross cash payment amount will be reduced by all applicable federal and state income and payroll taxes that the Bank is required to withhold to arrive at a net cash payment to be made to Employee under the CIC Agreement.

3.Full Settlement. Employee hereby agrees to accept the cut-back total payment under this Amendment to the CIC Agreement in full satisfaction of the cash payment due from Bank under his CIC Agreement and hereby releases Bank and its affiliates and successors, including, but not limited to Corporation, CBI and Catalyst, from any and all liability under said CIC Agreement, other than the obligation for said cut-back payment in accordance with the provisions of this Amendment.

4.Choice of Law and Forum. The parties agree that in any action brought to enforce the terms of the Agreement, Louisiana law shall be applicable.

5.Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the successors and assigns of Bank and Employee’s beneficiaries and heirs at law.

6.Entire Agreement; Modification. The CIC Agreement, as modified by this Amendment, contains the entire agreement of the parties and supersedes all promises, understandings or agreements, either oral or written, between the parties, and may not be modified except in writing and signed by the parties. Except as stated herein, the provisions of the CIC Agreement shall continue unchanged and in full force and effect, and the terms of the CIC Agreement are hereby ratified and approved as amended herein.

7.Severability. If any provision of this Amendment is declared invalid or unenforceable by a court of competent jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of any other provisions of this Amendment and the CIC Agreement and the remaining provisions of this Amendment and the CIC Agreement shall remain in full force and effect.

8.Terms not Defined. The Parties agree that the capitalized terms used herein that are not otherwise defined herein shall be deemed to have the definition assigned to such terms in the CIC Agreement.

9.Counterparts. This Amendment may be executed in multiple counterparts, each of which shall constitute an original.
