THE MERGER

Section 1.01 Terms of the Merger. Subject to the terms and conditions of this Agreement, at the Effective Time, ESSA shall merge with and into CNB, and CNB shall be the surviving entity (hereinafter sometimes referred to as the “Surviving Corporation”). Immediately thereafter, pursuant to the Plan of Bank Merger described in the following sentence, ESSA Bank shall merge with and into CNB Bank, and CNB Bank shall be the surviving entity (hereinafter sometimes referred to as the “Surviving Bank”) and shall continue to be governed by the laws of the Commonwealth of Pennsylvania. As soon as practicable after the execution of this Agreement, CNB will cause CNB Bank to, and ESSA will cause ESSA Bank to, execute and deliver a Plan of Bank Merger substantially in the form attached to this Agreement as Exhibit C. As part of the Merger, shares of ESSA Stock shall, at the Effective Time, be converted into the right to receive the Merger Consideration pursuant to the terms of Article II.

Section 1.02 Tax Consequences. It is intended that the Merger shall constitute a reorganization within the meaning of Section 368(a) of the Code, and that this Agreement shall constitute a “plan of reorganization” as that term is used in Sections 354, 361 and 368 of the Code. From and after the date of this Agreement and until the Closing, each party hereto shall use its reasonable best efforts to cause the Merger to qualify, and will not knowingly take any action, cause any action to be taken, fail to take any action or cause any action to fail to be taken, which action or failure to act would reasonably be expected to prevent the Merger from qualifying as a reorganization under Section 368(a) of the Code. CNB and ESSA each hereby agree to deliver a certificate substantially in compliance with IRS-published advance ruling guidelines, with customary exceptions and modifications thereto, to enable its counsel to deliver the legal opinions contemplated by Section 6.01(e).

Section 1.07 Effective Date and Effective Time; Closing.

(a) Subject to the terms and conditions of this Agreement, CNB will make all such filings as may be required by applicable laws and regulations to consummate the Merger. On the Closing Date, which shall take place not more than three (3) Business Days following the receipt of all necessary regulatory, governmental and shareholder approvals and consents and the expiration of all statutory waiting periods in respect thereof and the satisfaction or waiver of all of the conditions to the consummation of the Merger specified in Article VI of this Agreement (other than the delivery of certificates and other instruments and documents to be delivered at the Closing), or on such other date as the parties shall mutually agree to, CNB and ESSA shall file a statement of merger with the Department of State of the Commonwealth of Pennsylvania in accordance with the BCL. The

3

effective date of such filings is herein called the “Effective Date,” and the “Effective Time” of the Merger shall be as specified in such filing.

(b) The closing (the “Closing”) shall take place remotely via the electronic exchange of documents and signatures immediately prior to the Effective Time at 10:00 a.m., Eastern time, or in person at the principal offices of Hogan Lovells US LLP in Washington, D.C., or such other place, at such other time, or on such other date as the parties may mutually agree upon (such date, the “Closing Date”). At the Closing, there shall be delivered to CNB and ESSA the certificates and other documents required to be delivered under Article VI hereof.

Section 1.08 Alternative Structure. CNB may, at any time prior to the Effective Time, change the method of effecting the combination of CNB and ESSA, and CNB Bank and ESSA Bank, respectively, (including the provisions of this Article I) if and to the extent it deems such change to be reasonably necessary, appropriate or desirable; provided, however, that no such change shall (a) alter or change the Merger Consideration; (b) adversely affect the tax treatment of ESSA’s shareholders pursuant to this Agreement; (c) adversely affect the tax treatment of CNB or ESSA pursuant to this Agreement; or (d) be reasonably likely to materially impede or delay consummation of the transactions contemplated by this Agreement. In the event CNB makes such a change, ESSA agrees to execute an appropriate amendment to this Agreement in order to reflect such change.

Section 1.09 Additional Actions. If, at any time after the Effective Time, CNB shall consider or be advised that any further deeds, documents, assignments or assurances in law or any other acts are necessary or desirable to (a) vest, perfect or confirm, of record or otherwise, in CNB its right, title or interest in, to or under any of the rights, properties or assets of ESSA or ESSA Bank, or (b) otherwise carry out the purposes of this Agreement, ESSA, ESSA Bank and their respective officers and directors shall be deemed to have granted to CNB an irrevocable power of attorney to execute and deliver, in such official corporate capacities, all such deeds, assignments or assurances in law or any other acts as are necessary or desirable to (i) vest, perfect or confirm, of record or otherwise, in CNB or CNB Bank its right, title or interest in, to or under any of the rights, properties or assets of ESSA or ESSA Bank or (ii) otherwise carry out the purposes of this Agreement, and the officers and directors of CNB or CNB Bank are authorized in the name of ESSA or ESSA Bank or otherwise to take any and all such action.

Section 1.10 Absence of Control.

ARTICLE II

CONSIDERATION; EXCHANGE PROCEDURES

Section 2.01 Merger Consideration.

(a) Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of any Person:

(i) Each share of CNB Stock that is issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding following the Effective Time and shall be unchanged by the Merger.

(ii) Each share of ESSA Stock issued and outstanding immediately prior to the Effective Time (other than shares of ESSA Stock to be cancelled pursuant to Section 2.01(b) or shares of ESSA Restricted Stock, which shall instead be subject to the treatment set forth in Section 2.07(a)) shall become and be converted into the right to receive 0.8547 (the “Exchange Ratio”) shares of CNB Stock (the “Merger Consideration”).

4

(b) At the Effective Time, all shares of ESSA Stock that are owned by ESSA as treasury stock and all shares of ESSA Stock that are owned directly or indirectly by CNB or ESSA, including any shares of ESSA Stock held by CNB or ESSA or any of their respective Subsidiaries in respect of a debt previously contracted, other than shares that are held by CNB or ESSA, if any, in a fiduciary capacity, shall be canceled and shall cease to exist and no Merger Consideration shall be delivered in exchange therefor. All shares of CNB Stock that are owned by ESSA shall become treasury stock of CNB.

Section 2.02 Rights as Shareholders; Stock Transfers. All shares of ESSA Stock, when converted as provided in Section 2.01(a)(ii), shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each certificate previously evidencing such shares of ESSA Stock (each, a “Certificate”, it being understood that any reference herein to “Certificate” shall be deemed to include reference to book-entry account statements relating to the ownership of shares of ESSA Stock) shall thereafter represent only the right to receive for each such share of ESSA Stock, the Merger Consideration and, if applicable, any cash in lieu of fractional shares of CNB Stock in accordance with Section 2.03(f). At the Effective Time, holders of ESSA Stock shall cease to be, and shall have no rights as, shareholders of ESSA other than the right to receive the Merger Consideration and cash in lieu of fractional shares of CNB Stock as provided under this Article II. After the Effective Time, there shall be no transfers of shares of ESSA Stock on the stock transfer books of ESSA.

Section 2.03 Exchange Procedures.

(a) If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name a Certificate surrendered pursuant to Section 2.03(c) is registered, it shall be a condition to such payment that such Certificate shall be properly endorsed or otherwise be in proper form for transfer, as applicable, and the Person requesting such payment shall inform the Exchange Agent, pursuant to an agreement entered into prior to Closing, whether any transfer or other similar Taxes are required as a result of such payment to a Person other than the registered holder of such Certificate, or establish to the reasonable satisfaction of the Exchange Agent that such Taxes are not payable. If such transfer or other similar Taxes are payable pursuant to the preceding sentence, then the Exchange Agent shall withhold and deduct from the Merger Consideration (including cash in lieu of fractional shares of CNB Stock) otherwise payable pursuant to this Agreement to the designated Person other than the registered holder, such amounts as the Exchange Agent determines are necessary based on the information supplied by the registered holder. The Exchange Agent (or, subsequent to the twelve (12) month anniversary of the Effective Time, CNB) shall be entitled to deduct and withhold from the Merger Consideration (including cash in lieu of fractional shares of CNB Stock) otherwise payable pursuant to this Agreement to any holder of ESSA Stock such amounts as the Exchange Agent or CNB, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign Tax law, with respect to the making of such payment. To the extent that any amounts are withheld by the Exchange Agent or CNB, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of ESSA Stock in respect of whom such deduction and withholding was made by the Exchange Agent or CNB, as the case may be.

(b) At least one (1) Business Day prior to the Effective Time, CNB shall deposit, or shall cause to be deposited, with the Exchange Agent, for the benefit of the holders of ESSA Stock pursuant to this Article II (i) certificates, or at CNB’s option, evidence of shares in book-entry form, representing the shares of CNB Stock, sufficient to pay the aggregate Merger Consideration required pursuant to this Article II, and (ii) an aggregate amount of cash sufficient to pay the estimated amount of cash to be paid in lieu of fractional shares of CNB Stock, each to be given to the holders of ESSA Stock in exchange for Certificates pursuant to this Article II. Until the twelve (12) month anniversary of the Effective Time, CNB shall make available on a timely basis or cause to be made available to the Exchange Agent the following: (i) certificates, or at CNB’s option, evidence of shares in book-entry form, representing the shares of CNB Stock, sufficient to pay the aggregate Merger Consideration required pursuant to this Article II, and (ii) an aggregate amount of cash sufficient to pay the estimated amount of cash to be paid in lieu of fractional shares of CNB Stock, each to be given to the holders of

5

ESSA Stock in exchange for Certificates pursuant to this Article II. Upon such twelve (12) month anniversary, any such cash or certificates remaining in the possession of the Exchange Agent, together with any earnings in respect thereof, shall be delivered to CNB. Any holder of Certificates who has not theretofore exchanged his or her Certificates for the Merger Consideration pursuant to this Article II or who has not theretofore submitted a letter of transmittal, if required, shall thereafter be entitled to look exclusively to CNB, and only as a general creditor thereof, for the Merger Consideration, as applicable, to which he or she may be entitled upon exchange of such Certificates pursuant to this Article II. If outstanding Certificates are not surrendered, or the payment for the Certificates is not claimed prior to the date on which such payment would otherwise escheat to or become the property of any Governmental Authority, the unclaimed items shall, to the extent permitted by abandoned property and any other applicable law, become the property of CNB (and to the extent not in its possession shall be delivered to it), free and clear of all Liens of any Person previously entitled to such property. Neither the Exchange Agent nor any of the parties hereto shall be liable to any holder of ESSA Stock represented by any Certificate for any consideration paid to a public official pursuant to applicable abandoned property, escheat or similar laws. CNB and the Exchange Agent shall be entitled to rely upon the stock transfer books of ESSA to establish the identity of those Persons entitled to receive the Merger Consideration, which books shall be conclusive with respect thereto.

(c) Promptly after the Effective Time but no later than five (5) business days after the Closing Date, CNB shall cause the Exchange Agent to mail or deliver to each Person who was, immediately prior to the Effective Time, a holder of record of ESSA Stock a notice advising such holders of the effectiveness of the Merger, including a letter of transmittal in a form reasonably satisfactory to CNB and ESSA containing instructions for use in effecting the surrender of Certificates in exchange for the Merger Consideration which shall specify that delivery shall be effected, and risk of loss and title to Certificates shall pass, only upon with respect to shares evidenced by Certificates, proper delivery to the Exchange Agent of such Certificates and the transmittal materials, duly, completely and validly executed in accordance with the instructions thereto. Upon surrender to the Exchange Agent of a Certificate for cancellation together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, the holder of such Certificate shall promptly be provided in exchange therefor, but in no event later than five (5) Business Days after due surrender, (x) a certificate, or at the election of CNB, a statement reflecting shares issued in book-entry form, representing the number of whole shares of CNB Stock that such holder is entitled pursuant to this Article II, and (y) a check in the amount equal to the sum of (A) any cash in lieu of fractional shares pursuant to Section 2.03(f) and (B) any dividends or other distributions that such holder is entitled pursuant to Section 2.03(e), and the Certificate so surrendered shall forthwith be canceled. No interest will accrue or be paid with respect to any property to be delivered upon surrender of Certificates.

(d) 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 required by CNB or the Exchange Agent, the posting by such Person of a bond in customary amount as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, CNB shall cause the Exchange Agent to issue the Merger Consideration deliverable to such Person, and any cash, unpaid dividends or other distributions that would be payable or deliverable to such Person, in respect of the shares of ESSA Stock represented by such lost, stolen or destroyed Certificate.

(e) No dividends or other distributions with respect to CNB Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of CNB Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to subsection (f) below, and all such dividends, other distributions and cash in lieu of fractional shares of CNB Stock shall be paid by CNB to the Exchange Agent, in each case until the surrender of such Certificate in accordance with this Section 2.03. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Certificate there shall be paid to the holder of the whole shares of CNB Stock issued in exchange therefor, without interest, (i) at the time of such surrender, in addition to the Merger Consideration, the amount of dividends or other distributions with a record date after the Effective Time

6

theretofore paid with respect to such whole shares of CNB Stock and the amount of any cash payable in lieu of a fractional share of CNB Stock to which such holder is entitled pursuant to subsection (f), and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of CNB Stock. CNB shall make available to the Exchange Agent cash for these purposes, if necessary.

(f) Notwithstanding any other provision hereof, no fractional shares of CNB Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger; no dividend or distribution by CNB shall relate to such fractional share interests; and such fractional share interests will not entitle the owner thereof to vote or to any other rights as a stockholder of CNB. In lieu of any such fractional shares, CNB shall pay to each holder of a fractional share of CNB Stock an amount of cash (without interest) determined by multiplying the fractional share interest to which such holder would otherwise be entitled by the average of the daily closing prices during the regular session of CNB Stock as reported on NASDAQ for the five (5) consecutive trading days ending on the third (3rd) Business Day immediately prior to the Closing Date, rounded to the nearest whole cent (the “CNB Measurement Price”).

(g) CNB, in the exercise of its reasonable discretion, shall have the right to make all determinations, not inconsistent with the terms of this Agreement, governing (i) the issuance and delivery of shares of CNB Stock into which shares of ESSA Stock are converted in the Merger and (ii) the method of payment of cash in lieu of fractional shares of CNB Stock.

Section 2.04 Anti-Dilution Provisions. In the event CNB or ESSA changes (or establishes a record date for changing) the number of, or provides for the exchange of, shares of CNB Stock or ESSA Stock issued and outstanding prior to the Effective Time as a result of a stock split, stock dividend, recapitalization, reclassification, or similar transaction with respect to the outstanding CNB Stock or ESSA Stock and the record date therefor shall be prior to the Effective Time, the Exchange Ratio shall be proportionately and appropriately adjusted; provided, however, that, for the avoidance of doubt, no such adjustment shall be made with regard to CNB Stock if (a) CNB issues additional shares of CNB Stock and receives consideration for such shares in a bona fide third party transaction, (b) CNB issues additional shares of CNB Stock under the CNB Financial Corporation 2019 Omnibus Incentive Plan, or (c) CNB issues employee, director or other key service provider stock grants or similar equity awards or shares of CNB Stock upon the exercise or settlement thereof.

Section 2.05 Reservation of Shares. Effective upon the date of this Agreement, CNB shall reserve for issuance a sufficient number of shares of CNB Stock for the purpose of issuing shares of CNB Stock to ESSA shareholders in accordance with this Article II.

Section 2.06 Listing of Additional Shares. Prior to the Effective Time, CNB shall notify NASDAQ of the additional shares of CNB Stock to be issued by CNB in exchange for the shares of ESSA Stock.

Section 2.07 Treatment of Equity Awards and Cash-Settled Awards.

(a) Treatment of Restricted Stock Awards. Immediately prior to the Effective Time, any vesting or other forfeiture restrictions on each share of ESSA Stock subject to a substantial risk of forfeiture (“ESSA Restricted Stock”) outstanding as of immediately prior to the Effective Time shall, automatically and without any required action on the part of the holder thereof, accelerate in full and fully vest and shall be converted into, and become exchanged for the Merger Consideration within five (5) Business Days after the Effective Time, less applicable Taxes required to be withheld, if any, with respect to such vesting, and shall be treated as an issued and outstanding share of ESSA Stock for the purposes of this Agreement. For the avoidance of doubt, CNB shall not assume any ESSA Restricted Stock.

(b) Treatment of Performance Based Cash-Settled Awards. Immediately prior to the Effective Time, any vesting or other forfeiture restrictions applicable to each outstanding performance-based cash settled award

7

(“ESSA Cash-Settled Award”) outstanding as of immediately prior to the Effective Time shall, automatically and without any required action on the part of the holder thereof, accelerate in full and fully vest, with any applicable performance-based vesting condition to be deemed achieved at the greater of the target level of performance or actual annualized performance measured as of the most recent completed fiscal quarter, and shall be paid in cash within five (5) Business Days after the Effective Time, less applicable Taxes required to be withheld, if any, with respect to such vesting and payment.

(c) Additional Actions. Prior to the Effective Time, ESSA shall take all actions that may be necessary or required (under any ESSA Equity Plan, any applicable law, the applicable award agreements or otherwise) (i) to effectuate the provisions of this Section 2.07, (ii) to terminate each ESSA Equity Plan as of the Effective Time without any further obligation or liability, and (iii) to ensure that, from and after the Effective Time, holders of ESSA Restricted Stock and ESSA Cash-Settled Awards, as applicable, shall have no rights with respect thereto other than those rights specifically provided in this Section 2.07.

(d) Subject to Section 5.11(e), neither the ESSA Board nor any committee thereof shall (i) withdraw, qualify, amend, modify or withhold, or propose to withdraw, qualify, amend, modify or withhold, in a manner adverse to CNB in connection with the transactions contemplated by this Agreement (including the Merger), the ESSA Recommendation, fail to reaffirm the ESSA Recommendation within five (5) Business Days following a request by CNB, or make any statement, announcement or release, in connection with the ESSA Meeting or otherwise, inconsistent with the ESSA Recommendation (it being understood that taking a neutral position or no position with respect to an Acquisition Proposal shall be considered an adverse modification of the ESSA Recommendation); (ii) approve or recommend, or propose to approve or recommend, any Acquisition Proposal; or (iii) enter into (or cause ESSA to enter into) any letter of intent, agreement in principle, acquisition agreement or other agreement (A) related to any Acquisition Transaction (other than a confidentiality agreement entered into in accordance with the provisions of Section 5.11(b)) or (B) requiring ESSA to abandon, terminate or fail to consummate the Merger or any other transaction contemplated by this Agreement.

(e) Notwithstanding anything to the contrary set forth in this Agreement, prior to the ESSA Meeting, the ESSA Board may withdraw, qualify, amend or modify the ESSA Recommendation in connection therewith (an “ESSA Subsequent Determination”) and/or terminate this Agreement pursuant to Section 7.01(g)(ii) after the fourth (4th) Business Day following CNB’s receipt of a written notice (the “Notice of Superior Proposal”) from ESSA advising CNB that the ESSA Board intends to determine that a bona fide unsolicited written Acquisition Proposal that it received (that did not result from a breach of this Section 5.11) constitutes a Superior Proposal if, but only if, (i) the ESSA Board has reasonably determined in good faith, after consultation with outside legal counsel, that it is required to take such actions to comply with its fiduciary duties under applicable law, (ii) during the three (3) Business Day period after receipt of the Notice of Superior Proposal by CNB (the “Notice Period”), ESSA and the ESSA Board shall have cooperated and negotiated in good faith with CNB to make such adjustments, modifications or amendments to the terms and conditions of this Agreement as would enable ESSA to proceed with the ESSA Recommendation without an ESSA Subsequent Determination; provided, however, that CNB shall not have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of this Agreement, and (iii) at the end of the Notice Period, after taking into account any such adjusted, modified or amended terms as may have been proposed by CNB since its receipt of such Notice of Superior Proposal, the ESSA Board in good faith makes the determination (A) in clause (i) of this Section 5.11(e) and (B) that such Acquisition Proposal constitutes a Superior Proposal. In the event of any material revisions to the Superior Proposal, ESSA shall be required to deliver a new Notice of Superior Proposal to CNB and again comply with the requirements of this Section 5.11(e), except that the Notice Period shall be reduced to two (2) Business Days. In addition to the foregoing, the ESSA Board shall not submit to the vote of its stockholders any Acquisition Proposal other than the Merger at the ESSA Meeting.

(f) Nothing contained in this Section 5.11 shall prohibit ESSA or the ESSA Board from complying with ESSA’s obligations required under Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or from making any legally required disclosure to ESSA’s shareholders; provided, however, that any such disclosure relating to an Acquisition Proposal shall be deemed a change in the ESSA Recommendation unless it is limited to

40

a stop, look and listen communication or the ESSA Board reaffirms the ESSA Recommendation in such disclosure.

Section 5.12 Certain Policies. Prior to the Effective Date, ESSA shall, consistent with GAAP and applicable banking laws and regulations, modify or change its loan, OREO, accrual, reserve, tax, litigation and real estate valuation policies and practices (including loan classifications and levels of reserves) so as to be applied on a basis that is consistent with that of CNB; provided, however, that ESSA shall not be obligated to take any action pursuant to this Section 5.12 unless and until all Regulatory Approvals have been obtained and CNB acknowledges in writing, and ESSA is satisfied, that all conditions to ESSA’s obligation to consummate the Merger have been satisfied and that CNB shall consummate the Merger in accordance with the terms of this Agreement, and further provided that in any event, no accrual or reserve made by ESSA pursuant to this Section 5.12 or the consequences resulting therefrom shall constitute or be deemed to be a breach, violation of or failure to satisfy any representation, warranty, covenant, agreement, condition or other provision of this Agreement or otherwise be considered in determining whether any such breach, violation or failure to satisfy shall have occurred. The recording of any such adjustments shall not be deemed to imply any misstatement of previously furnished financial statements or information and shall not be construed as concurrence of ESSA or its management with any such adjustments, nor any admission that the previously furnished financial statements or information did not fully comply in all respects with GAAP or regulatory requirements.

Section 5.13 Indemnification.

(a) From and after the Effective Time, CNB (the “Indemnifying Party”) shall indemnify and hold harmless each present and former director and officer of ESSA or ESSA Bank, as applicable, determined as of the Effective Time (the “Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, amounts paid in settlement, fines, penalties, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, and whether formal or informal (each, a “Proceeding”) arising out of matters existing or occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, arising in whole or in part out of or pertaining to the fact that he or she was a director or officer of ESSA or ESSA Bank or is or was serving at the request of ESSA or ESSA Bank as a director, officer, employee or other agent of any other organization or in any capacity with respect to any employee benefit plan of ESSA or ESSA Bank, including without limitation matters related to the negotiation, execution and performance of this Agreement or any of the transactions contemplated hereby, to the fullest extent which such Indemnified Parties would be entitled under the BCL or the Articles of Incorporation and the Bylaws of ESSA or ESSA Bank as in effect on the date hereof (subject to change as required by law), including with respect to the advancement of expenses. Notwithstanding any other provision of this Section 5.13, the Indemnifying Party shall advance all reasonable costs, expenses and fees (including reasonable attorneys’ fees) incurred by or on behalf of an Indemnified Party in connection with any Proceeding within thirty (30) days after the receipt by the Indemnifying Party of a statement or statements from the Indemnified Party requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall be made in good faith and shall reasonably evidence the costs, expenses and fees incurred by the Indemnified Party (which shall include invoices in connection with such costs, fees and expenses but, in the case of invoices in connection with legal services, any references to legal work performed or to expenditure made that would cause the Indemnified Party to waive any privilege or protection accorded by applicable law shall not be included with the invoice), and shall include or be preceded or accompanied by a written undertaking by or on behalf of the Indemnified Party to repay any costs, expenses or fees advanced if it shall ultimately be determined that the Indemnified Party is not entitled to be indemnified against such costs, expenses or fees. Any advances and undertakings to repay pursuant to this Section 5.13 shall be unsecured and interest free and made without regard to the Indemnified Party’s ability to repay such advances or ultimate entitlement to indemnification.

(b) Any Indemnified Party wishing to claim indemnification under this Section 5.13, upon learning of any such Proceeding, shall promptly notify the Indemnifying Party, but the failure to so notify shall not relieve the

41

Indemnifying Party of any liability it may have to such Indemnified Party except to the extent that such failure does actually prejudice the Indemnifying Party. In the event of any such Proceeding (whether arising before or after the Effective Time), (i) the Indemnifying Party shall have the right to assume the defense thereof with counsel which is reasonably satisfactory to the Indemnified Party and the Indemnifying Party shall not be liable to such Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that if the Indemnifying Party elects not to assume such defense or counsel for the Indemnified Parties advises that there are issues which raise actual or potential conflicts of interest between the Indemnifying Party and the Indemnified Parties, the Indemnified Parties may retain counsel which is reasonably satisfactory to the Indemnifying Party, and the Indemnifying Party shall pay, promptly as statements therefor are received, the reasonable fees and expenses of such counsel for the Indemnified Parties (which may not exceed one firm in any jurisdiction unless counsel for the Indemnified Parties advises that there are issues that raise conflicts of interest between the Indemnified Parties), (ii) the Indemnified Parties will reasonably cooperate in the defense of any such matter, (iii) the Indemnifying Party shall not be liable for any settlement effected without its prior written consent and (iv) the Indemnifying Party shall have no obligation hereunder in the event that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable laws and regulations or by a final non-appealable adjudication of an applicable federal or state banking agency or a court of competent jurisdiction.

(c) Prior to the Effective Time, CNB shall purchase an extended reporting period endorsement under ESSA’s existing directors’ and officers’ liability insurance coverage for ESSA’s directors and officers in a form acceptable to ESSA which shall provide such directors and officers with coverage for six years following the Effective Time for claims made against such directors and officers arising from any act, error or omission by such directors and officers existing or occurring at or prior to the Effective Time of not less than the existing coverage under, and have other terms at least as favorable to, the directors and officers than the directors’ and officers’ liability insurance coverage presently maintained by ESSA (provided that CNB may substitute therefor policies which are not materially less advantageous than such policy or single premium tail coverage with policy limits equal to ESSA’s existing coverage limits), so long as the aggregate cost is not more than 250% of the annual premium currently paid by ESSA for such insurance (the “Premium Limit”). In the event that the Premium Limit is insufficient for such coverage, CNB shall use its reasonable best efforts to purchase such lesser coverage as may be obtained with such amount.

(d) The rights of indemnification and advancement as provided by this Section 5.13 shall not be deemed exclusive of any other rights to which the Indemnified Party may at any time be entitled under the Articles of Incorporation and the Bylaws of ESSA or as provided in applicable law as in effect on the date hereof (subject to change as required by law), any agreement, a vote of stockholders, a resolution of directors of ESSA, or otherwise. In the event that an Indemnified Party, pursuant to this Section 5.13, seeks an adjudication of such person’s rights under, or to recover damages for breach of, this Section 5.13, or to recover under any directors’ and officers’ liability insurance coverage maintained by ESSA or CNB, the Indemnifying Party shall pay on such Indemnified Party’s behalf, any and all reasonable costs, expenses and fees (including reasonable attorneys’ fees ) incurred by such Indemnified Party in such judicial adjudication, to the fullest extent permitted by law, only to the extent that the Indemnified Party prevails in such judicial adjudication.

(e) If CNB or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger, or shall transfer all or substantially all of its assets to any other entity, then and in each case, proper provision shall be made so that the successors and assigns of CNB shall assume the obligations set forth in this Section 5.13.

Section 5.14 Employees; Benefit Plans.

(a) Following the Closing Date and except to the extent an alternative treatment is set forth in this Section 5.14, CNB may choose to maintain any or all of the ESSA Benefit Plans in its sole discretion, and ESSA and ESSA Bank shall cooperate with CNB and CNB Bank in order to effect any plan terminations to be made as

42

of the Effective Time as set forth in this Section 5.14 and in accordance with the terms of the applicable ESSA Benefit Plans and applicable law. For the period commencing at the Effective Time and ending twelve (12) months after the Effective Time (or until the applicable Continuing Employee’s earlier termination of employment), CNB shall provide, or cause to be provided, to each employee of ESSA Bank who continues with the Surviving Bank as of the Closing Date (a “Continuing Employee”) (i) a base salary or a base rate of pay at least equal to the base salary or base rate of pay provided to such Continuing Employee by ESSA Bank as immediately prior to the Effective Time, and (ii) other benefits (other than severance or termination pay in order to avoid a duplication of benefits, if applicable) substantially comparable in the aggregate to the benefits provided to similarly situated employees of CNB or any Subsidiary of CNB. For any ESSA Benefit Plan terminated for which there is a comparable CNB Benefit Plan of general applicability, CNB shall take all commercially reasonable action so that Continuing Employees shall be entitled to participate in such CNB Benefit Plan to the same extent as similarly-situated employees CNB (it being understood that inclusion of the employees of ESSA and ESSA Bank in the CNB Benefit Plans may occur at different times with respect to different plans). CNB shall cause each CNB Benefit Plan in which Continuing Employees are eligible to participate to take into account for purposes of eligibility and vesting under the CNB Benefit Plans (but not for purposes of benefit accrual) the service of such employees with ESSA or ESSA Bank to the same extent as such service was credited for such purpose by ESSA or ESSA Bank; provided, however, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits or retroactive application. Nothing herein shall limit the ability of CNB or CNB Bank to amend or terminate any of the ESSA Benefit Plans or CNB Benefit Plans in accordance with their terms at any time. Following the Closing Date, CNB shall honor, in accordance with ESSA’s policies and procedures in effect as of the date hereof, any employee expense reimbursement obligations of ESSA for out-of-pocket expenses incurred during the calendar year in which the Closing occurs by any Continuing Employee and all accrued but unused vacation credited to any Continuing Employee under ESSA Benefit Plans.

(b) Without limiting the generality of Section 5.14(a), prior to the Closing Date, if requested by CNB in writing not less than thirty (30) days prior to the Closing Date, ESSA or ESSA Bank, as applicable, shall take all actions necessary to cease contributions to and terminate each ESSA Benefit Plan that is intended to qualify under Code Section 401(k) (each, an “ESSA 401(k) Plan”), and to adopt written resolutions, the form and substance of which shall be reasonably satisfactory to CNB, to terminate such ESSA 401(k) Plan; provided, however, that such termination may be made contingent upon the consummation of the transactions contemplated by this Agreement. In such event, CNB shall take any and all actions as may be required to permit Continuing Employees to participate in a CNB Benefit Plan that is intended to qualify under Code Section 401(k) (a “CNB 401(k) Plan”) immediately following the Closing Date and to permit Continuing Employees to roll over their account balances in the ESSA 401(k) Plan, including any participant loans under the ESSA 401(k) Plan, into the CNB 401(k) Plan. If requested by CNB in writing at any time following the date of this Agreement, ESSA or ESSA Bank, as applicable, shall initiate the process to terminate its tax-qualified defined benefit pension plan, with such termination effective as soon as practicable after the Effective Time, and ESSA shall keep CNB informed regarding the progress and status of the termination process.

(c) If employees of ESSA or ESSA Bank become eligible to participate in a medical, dental, vision, prescription drug, disability plan or life insurance plan of CNB or CNB Bank upon termination of such plan of ESSA or ESSA Bank, CNB or CNB Bank shall use commercially reasonable efforts to cause each such plan to (i) waive any preexisting condition limitations to the extent such conditions are covered under the applicable CNB Benefit Plan, (ii) provide credit under such plans for any deductible, co-payment and out-of-pocket expenses incurred by the employees and their beneficiaries during the portion of the calendar year that includes the Closing and prior to such participation and (iii) waive any waiting period limitation, actively-at-work requirement or evidence of insurability requirement which would otherwise be applicable to such employee on or after the Effective Time, in each case to the extent such employee had satisfied any similar limitation or requirement under an analogous ESSA Benefit Plan prior to the Effective Time; provided, however, that CNB shall not cause any coverage of a Continuing Employee or such Continuing Employee’s dependents to terminate under any ESSA Benefit Plan which is a group health plan prior to the time such Continuing Employees or such

43

Continuing Employee’s dependents, as applicable, have been offered participation in the group health plans common to all employees of CNB and their dependents, except in the case of a termination of employment or other service.

(d) From and after the Effective Time, CNB agrees to honor all obligations under the employment agreements, change in control agreements, supplemental executive retirement plans, split dollar life insurance and similar arrangements as set forth on ESSA Disclosure Schedule 5.14(d), in each case in accordance with their terms. ESSA Disclosure Schedule 5.14(d) sets forth the names of all participants, the value of each participant’s account balance and the amount of each lump sum or installment payment under each applicable non-qualified deferred compensation plan.

(e) Subject to the occurrence of the Closing, the ESSA Bank ESOP shall be terminated by ESSA Bank no later than the fifth (5^th) Business Day prior to the Closing Date. In connection with the termination of the ESSA Bank ESOP, all plan accounts shall be fully vested, all outstanding indebtedness of the ESSA Bank ESOP shall be repaid by delivering a sufficient number of unallocated shares of ESSA Stock to ESSA, at least five (5) Business Days prior to the Effective Time, all remaining shares of ESSA Stock held by the ESSA Bank ESOP shall be converted into the right to receive the Merger Consideration, and the balance of the unallocated shares and any other unallocated assets remaining in the ESSA Bank ESOP after repayment of the ESSA Bank ESOP loan shall be allocated as earnings to the accounts of the ESSA Bank ESOP participants who are employed as of the date of termination of the ESSA Bank ESOP based on their account balances under the ESSA Bank ESOP as of the date of termination of the ESSA Bank ESOP and distributed to ESSA Bank ESOP participants after the receipt of a favorable determination letter from the IRS, except for distributions required by law, which, for purposes of clarity, includes certain terminations of employment. Prior to the Effective Time, ESSA Bank shall take all such actions as are necessary (determined in consultation with CNB) to submit the application for favorable determination letter in advance of the Effective Time. ESSA Bank will adopt such amendments to the ESSA Bank ESOP to effect the provisions of this Section 5.14(e). Promptly following the receipt of a favorable determination letter from the IRS regarding the qualified status of the ESSA Bank ESOP upon its termination, the account balances in the ESSA Bank ESOP shall either be distributed to participants and beneficiaries or transferred to an eligible tax-qualified retirement plan or individual retirement account as a participant or beneficiary may direct; provided, however, that nothing contained herein shall delay the distribution or transfer of account balances in the ESSA Bank ESOP in the ordinary course for reasons other than the termination of such plan. Prior to the Closing Date, ESSA Bank shall provide CNB with the final documentation evidencing that the actions contemplated herein have been effectuated. Notwithstanding anything herein to the contrary, ESSA Bank shall continue to accrue and make contributions to the ESSA Bank ESOP trust from the date of this Agreement through the termination date of the ESSA Bank ESOP in an amount sufficient (but not to exceed) the loan payments which become due in the ordinary course on the outstanding loans to the ESSA Bank ESOP prior to the termination of the ESSA Bank ESOP and shall make a pro-rated payment on the ESSA Bank ESOP loan for the 2025 plan year through and including the end of the calendar quarter immediately preceding the Closing, prior to the termination of the ESSA Bank ESOP.

(f) CNB agrees to pay to each employee of ESSA or ESSA Bank that is not covered by a written employment or severance agreement and is terminated by CNB, CNB Bank or any of their Subsidiaries, without cause, within six (6) months following the Effective Time, a severance payment equal to two (2) weeks of his or her then current base salary multiplied by the number of total completed years of service (a partial year of service of three months or more shall be counted as a completed year of service), with ESSA or ESSA Bank; provided, however, that the minimum severance payment shall equal not less than four (4) weeks of his or her base salary and the maximum severance payment shall not exceed twenty-six (26) weeks of his or her base salary; and provided further, that such employee enters into and does not revoke a release of claims in a form reasonably satisfactory to CNB and that such employee does not voluntarily leave employment with ESSA or ESSA Bank prior to the Effective Time.

(g) To the extent necessary, CNB and ESSA may provide a retention pool in an aggregate amount up to $250,000 as mutually agreed by CNB and ESSA to enable CNB and ESSA to provide retention incentives to

44

certain employees of ESSA or ESSA Bank who are not covered by a written employment agreement or change in control agreement, the recipients and individual amounts to be determined by CNB, in its sole discretion, in consultation with and upon the recommendation of ESSA’s chief executive officer. Such retention incentives will be in addition to, and not in lieu of, any severance payment, including the amount that may be paid pursuant to Section 5.14(f). Such designated employees will enter into retention agreements to be provided by CNB.

(h) CNB and ESSA will enter into a settlement agreement and a non-competition agreement with the individuals named in ESSA Disclosure Schedule 5.14(h) and in the form set forth in ESSA Disclosure Schedule 5.14(h), and which will be signed and dated by the parties on the same date this Agreement is executed.

(i) Nothing contained in this Agreement, expressed or implied, shall (i) give any person, other than the parties hereto, any rights or remedies of any nature whatsoever, including any right to continued employment or service, under or by reason of this Section 5.14, (ii) cause any third party beneficiary rights in any current or former employee, director, other individual service provider of ESSA or any of its Subsidiaries to enforce the provisions of this Section 5.14 or any other matter related thereto, or (iii) be construed as an amendment to any ESSA Benefit Plan, CNB Benefit Plan, or other employee benefit plan of CNB, CNB Bank, ESSA or any of their respective Affiliates, or be construed to prohibit the amendment or termination of any such plan.

(j) Prior to making any broad-based communications to the ESSA Employees pertaining to compensation or benefits matters that are affected by the transactions contemplated by this Agreement, ESSA and ESSA Bank shall (i) provide CNB and CNB Bank with a copy or written summary of the intended communication, (ii) give CNB and CNB Bank a reasonable period of time to review and comment on the intended communication and (iii) consider any such comments in good faith.

(k) If requested by CNB, ESSA shall take all such actions as CNB may request in order to fully and timely comply with any and all requirements of the WARN Act, including providing notices to employees of ESSA or any Subsidiary of ESSA.

Section 5.15 Notification of Certain Changes. Each of CNB and ESSA shall promptly advise the other party of any change or event having, or which could be reasonably expected to have, a Material Adverse Effect on it or which it believes would, or which could reasonably be expected to, cause or constitute a material breach of any of its representations, warranties or covenants contained herein. From time to time prior to the Effective Time, but no more frequently than monthly (and no later than the date prior to the Closing Date), each party will supplement or amend its Disclosure Schedules delivered in connection with the execution of this Agreement to reflect any matter which, if existing, occurring or known at the date of this Agreement, would have been required to be set forth or described in such Disclosure Schedules or which is necessary to correct any information in such Disclosure Schedules which has been rendered inaccurate thereby. No supplement or amendment to such Disclosure Schedules shall have any effect for the purpose of determining the accuracy of the representations and warranties of the parties contained in Article III and Article IV in order to determine the fulfillment of the conditions set forth in Section 6.02(a) or Section 6.03(a) hereof, as the case may be, or the compliance by ESSA or CNB, as the case may be, with the respective covenants and agreements of such parties contained herein.

Section 5.16 Current Information. During the period from the date of this Agreement to the Effective Time, ESSA will cause one or more of its designated representatives to confer on a regular and frequent basis with representatives of CNB and to report the general status of the ongoing operations of ESSA. Without limiting the foregoing, ESSA agrees to provide CNB a copy of each report filed by ESSA with a Governmental Authority within one (1) Business Day following the filing thereof (except as to reports filed with the SEC on the Edgar system).

Section 5.17 Board Packages. ESSA shall distribute a copy of each ESSA Board package, including the agenda and any draft minutes, to CNB at the same time and in the same manner in which it distributes a copy of such packages to the ESSA Board; provided, however, that ESSA shall not be required to copy CNB on any

45

documents that disclose confidential discussions of this Agreement or the transactions contemplated hereby or any third party proposal to acquire control of ESSA or any other matter that the ESSA Board has been advised of by counsel that such distribution to CNB may violate a confidentiality obligation, any material legal privilege or fiduciary duty or any law or regulation.

Section 5.18 Transition; Informational Systems Conversion. From and after the date hereof, CNB and ESSA shall each use their reasonable best efforts to facilitate the integration of ESSA with the business of CNB following consummation of the transactions contemplated by this Agreement, and shall meet on a regular basis to discuss and plan for the conversion of ESSA’s data processing and related electronic informational systems (the “Informational Systems Conversion”) to those used by CNB and its Subsidiaries, which planning shall include, but not be limited to: (a) discussion of ESSA’s third-party service provider arrangements; (b) non-renewal of personal property leases and software licenses used by ESSA in connection with its systems operations; (c) retention of outside consultants and additional employees to assist with the conversion; (d) outsourcing, as appropriate, of proprietary or self-provided system services; and (e) any other actions necessary and appropriate to facilitate the conversion, as soon as practicable following the Effective Time. If this Agreement is terminated by CNB and/or ESSA in accordance with Section 7.01(a), Section 7.01(c), or Section 7.01(f), or by ESSA only in accordance with Section 7.01(d) or Section 7.01(e), CNB shall pay to ESSA all reasonable fees, expenses or charges related to reversing the Informational Systems Conversion within ten (10) Business Days of ESSA providing CNB written evidence of such fees, expenses or charges.

Section 5.19 Intentionally Omitted.

Section 5.20 Section 16 Matters. Prior to the Effective Time, each of the ESSA Board and the CNB Board, or a committee of non-employee directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall take all such reasonable action as may be required to cause to be exempt from liability pursuant to Rule 16b-3 under the Exchange Act, to the fullest extent permitted by applicable law, any acquisitions or dispositions of shares of ESSA Stock and CNB Stock (including derivative securities with respect to such shares) that are treated as acquisitions or dispositions under such rule and result from the transactions contemplated by this Agreement by officers and directors of ESSA subject to the reporting requirements of Section 16(a) of the Exchange Act or by each individual who is reasonably expected to become subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to CNB immediately after the Effective Time.

Promptly following the Effective Time, CNB Bank shall invite up to twelve (12) directors of ESSA who are serving in such capacity immediately prior to the Effective Time, other than the New Board Members, or other market business and community leaders as recommended by the ESSA Chief Executive Officer and approved by CNB, to join a newly formed ESSA Bank Division Advisory Board of CNB Bank; provided that any director or officer of ESSA invited to join the ESSA Bank Division Advisory Board must meet the applicable qualifications of such advisory board in order to join.

Section 5.22 Community Matters. CNB agrees to support ESSA’s and ESSA Bank’s current and pending community matters support commitments and after the Effective Time shall provide annual community support in ESSA’s and ESSA Bank’s current market areas in an amount equal to or greater than the level of support provided by ESSA and/or ESSA Bank as of the date hereof, as set forth on ESSA Disclosure Schedule 5.22.

All Regulatory Approvals shall have been obtained and shall remain in full force and effect, any requirements contained in the Regulatory Approvals to be completed on or before the Closing Date shall have been completed, and all statutory waiting periods in respect thereof shall have expired or been terminated. No Regulatory Approvals referred to in this Section 6.01(a) shall contain any condition, restriction or requirement which the CNB Board, on the one hand, or the ESSA Board, on the other hand, reasonably determines in good faith would, individually or in the aggregate, materially reduce the benefits of the Merger to such a degree that CNB, on the one hand, or ESSA, on the other hand, would not have entered into this Agreement had such condition, restriction or requirement been known at the date hereof.

(b) Merger Registration Statement Effective. The Merger Registration Statement shall have been declared effective by the SEC and no stop order with respect thereto shall be in effect.

(c) NASDAQ Listing. The shares of CNB Stock issuable pursuant to this Agreement shall have been approved for listing on NASDAQ, subject to official notice of issuance.

(d) No Injunctions or Restraints; Illegality. No judgment, order, injunction or decree issued by any court or agency of competent jurisdiction or other legal restraint or prohibition preventing the consummation of any of the transactions contemplated by this Agreement shall be in effect.

(e) Tax Opinions. CNB shall have received a letter setting forth the written opinion of Hogan Lovells US LLP (or such other counsel reasonably acceptable to ESSA) in and form and substance reasonably satisfactory to CNB, dated as of the Closing Date, and ESSA shall have received a letter setting forth the written opinion of Luse Gorman, PC (or such other counsel reasonably acceptable to CNB) in form and substance reasonably satisfactory to ESSA, dated as of the Closing Date, in each case substantially to the effect that, on the basis of the facts, representations and assumptions set forth in such letter, the Merger will constitute a tax free reorganization described in Section 368(a) of the Code.

NOW, THEREFORE, in consideration of the promises, representations, warranties and agreements contained herein, and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

Section 1. Agreement to Vote Shares. Shareholder agrees that, while this Agreement is in effect, at any meeting of shareholders of ESSA, however called, or at any adjournment thereof, or in any other circumstances in which Shareholder is entitled to vote, consent or give any other approval, except as otherwise agreed to in writing in advance by CNB, Shareholder shall:

Section 2. No Transfers. While this Agreement is in effect, Shareholder agrees not to, directly or indirectly, sell, transfer, pledge, assign or otherwise dispose of, or enter into any contract, option, commitment or other arrangement or understanding with respect to the sale, transfer, pledge, assignment or other disposition of, any of the Shares, except the following transfers shall be permitted: (a) transfers by will or operation of law, in which case this Agreement shall bind the transferee, (b) transfers pursuant to any pledge agreement, subject to the pledgee agreeing in writing to be bound by the terms of this Agreement, (c) transfers in connection with estate and tax planning purposes, including transfers to relatives, trusts and charitable organizations, subject to the transferee agreeing in writing to be bound by the terms of this Agreement, (d) surrendering Shares to ESSA in

Any transfer or other disposition in violation of the terms of this Section 2 shall be null and void.

Section 3. Representations and Warranties of Shareholder. Shareholder represents and warrants to and agrees with CNB as follows:

Section 4. Irrevocable Proxy. Subject to the last sentence of this Section 4, by execution of this Agreement, Shareholder does hereby appoint CNB with full power of substitution and resubstitution, as Shareholder’s true and lawful attorney and irrevocable proxy, to the full extent of Shareholder’s rights with respect to the Shares, to vote, if Shareholder is unable to perform his, her or its obligations under this Agreement, each of such Shares that Shareholder shall be entitled to so vote with respect to the matters set forth in Section 1 hereof at any meeting of the shareholders of ESSA, and at any adjournment or postponement thereof, and in connection with any action of the shareholders of ESSA taken by written consent.

Shareholder acknowledges that it will be impossible to measure in money the damage to CNB if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, CNB will not have an adequate remedy at law or in equity. Accordingly, Shareholder agrees that injunctive relief or other equitable remedy, in addition to remedies at law or in damages, is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that CNB has an adequate remedy at law.

Upon any such termination, no party shall have any further obligations or liabilities hereunder; provided, however, such termination shall not relieve any party from liability for any willful breach of this Agreement prior to such termination.

Section 8. Entire Agreement; Amendments. This Agreement supersedes all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof. This Agreement may not be amended, supplemented or modified, and no provisions hereof may be modified or waived, except by an instrument in writing signed by each party hereto. No waiver of any provisions hereof by either party shall be deemed a waiver of any other provisions hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

Section 9. Severability. In the event that any one or more provisions of this Agreement shall for any reason be held invalid, illegal or unenforceable in any respect, by any court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement and the parties shall use their reasonable efforts to substitute a valid, legal and enforceable provision which, insofar as practical, implements the purposes and intents of this Agreement.

Section 10. Capacity as Shareholder. The covenants contained herein shall apply to Shareholder solely in his or her capacity as a shareholder of ESSA, and no covenant contained herein shall apply to Shareholder in his or her capacity as a director, officer or employee of ESSA or in any other capacity. Nothing contained in this Agreement shall be deemed to apply to, or limit in any manner, the obligations of Shareholder to comply with his or her fiduciary duties as a director or officer, as applicable, of ESSA.

Section 11. Governing Law. This Agreement shall be governed by, and interpreted in accordance with, the laws of Commonwealth of Pennsylvania, without regard for conflict of law provisions.

Section 12. Notice.

Olson (the “Executive”), ESSA Bancorp, Inc., a Pennsylvania corporation (“ESSA”), CNB Financial Corporation, a Pennsylvania corporation (the “Company”), and ESSA Bank & Trust, a wholly-owned subsidiary of ESSA (“ESSA Bank”).

WITNESSETH:

WHEREAS, concurrently with the execution of this Agreement, CNB Financial Corporation, a Pennsylvania Corporation, CNB Bank, a Pennsylvania-chartered nonmember bank and wholly-owned subsidiary of CNB Financial Corporation, ESSA Bancorp, Inc. a Pennsylvania Corporation, and ESSA Bank & Trust, a Pennsylvania-chartered stock savings bank and wholly-owned subsidiary of ESSA Bancorp, Inc., are entering into an Agreement and Plan of Merger, dated as of January 9, 2025 (the “Merger Agreement”), and all capitalized terms not defined herein shall have the meaning set forth in the Merger Agreement; and

WHEREAS, the Company, ESSA, ESSA Bank and the Executive desire to enter into this Agreement, which shall supersede in its entirety the Amended and Restated Employment Agreement by and among ESSA, ESSA Bank and the Executive, dated April 23, 2013 (the “Employment Agreement”), effective immediately prior to the Effective Time of the Merger, and in lieu of any rights and payments and benefits under the Employment Agreement, the Executive shall be entitled to the rights and payments set forth herein.

NOW THEREFORE, in consideration of the foregoing and other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the Executive, the Company, ESSA and ESSA Bank agree as follows:

1. Cancellation of Employment Agreement. Effective as of the Effective Time of the Merger, the Employment Agreement shall be cancelled in its entirety and the parties thereto shall have no further rights or obligations thereunder. In the event that the Merger Agreement is terminated or otherwise cancelled, this Agreement will be null and void ab initio, and the Employment Agreement will remain in full force and effect in accordance with its terms.

2. Cash Payment. Provided the Executive has remained employed with ESSA and ESSA Bank to and including the Closing Date and provided that the Executive has executed the release substantially in the form attached hereto as Exhibit A at least seven (7) days prior to the Closing Date (and any revocation period has elapsed), in exchange for the termination of the Employment Agreement and in accordance with Section 4 of the Employment Agreement, and in further consideration for the post-employment restrictions in Section 5 of this Agreement, ESSA Bank shall, or shall cause an affiliate to, pay to the Executive a lump-sum cash amount equal to an estimated $3,723,972, less applicable tax withholdings (the “Cash Payment”). For the avoidance of doubt, the Cash Payment includes amounts satisfying the obligation to provide the benefits coverage set forth in Section 4(d) of the Employment Agreement. The amount of the Cash Payment will be recalculated to reflect the updated actuarial value for the additional years of service under the ESSA Bank and Trust Pension Plan (the “Pension Plan”) as of the Closing Date as if the Pension Plan were no longer frozen to benefit accruals. The Cash Payment shall be paid to the Executive on or immediately prior to the Closing Date. The Cash Payment shall be further reduced pursuant to Section 6 of this Agreement as may be needed.

3. Termination of Employment. Without further action by either party, the Executive’s employment shall automatically terminate on the two (2) week anniversary of the Closing Date.

4. Complete Satisfaction. The Executive agrees that the full payment of the Cash Payment, as determined in accordance with Section 2 of this Agreement, shall be in complete satisfaction of all rights to payments due to Executive under the Employment Agreement.

5. Non-Competition and Non-Solicitation Restrictions.

(a) In exchange for the payment of the Cash Payment, the Executive hereby covenants and agrees that, for a period of two years following his termination of employment with ESSA and ESSA Bank, he shall not, without the written consent of ESSA or ESSA Bank, either directly or indirectly:

(i) solicit, offer employment to, or take any other action intended (or that a reasonable person acting in like circumstances would expect) to have the effect of causing any officer or employee of ESSA or ESSA Bank or any of its affiliates to terminate his or her employment and accept employment or become affiliated with, or provide services for compensation in any capacity whatsoever to, any business whatsoever that competes with the business of ESSA, ESSA Bank, or any of their affiliates or has headquarters or offices within 50 miles of the locations in which ESSA, ESSA Bank or their affiliates have business operations or has filed an application for regulatory approval to establish an office;

(ii) become an officer, employee, consultant, director, independent contractor, agent, sole proprietor, joint venturer, greater than 5% equity-owner or stockholder, partner or trustee of any savings bank, savings and loan association, savings and loan holding company, credit union, bank or bank holding company, insurance company or agency, any mortgage or loan broker or any other entity competing with ESSA, ESSA Bank or their affiliates in the same geographic locations where ESSA, ESSA Bank or their affiliates have material business interests; or

(iii) solicit, provide any information, advice or recommendation or take any other action intended (or that a reasonable person acting in like circumstances would expect) to have the effect of causing any customer of the ESSA, ESSA Bank or their affiliates to terminate an existing business or commercial relationship with ESSA, ESSA Bank or their affiliates.

(b) Executive shall, upon reasonable notice, furnish such information and assistance to the Employer and/or its affiliates, as may reasonably be required by the Employer and/or its affiliates, in connection with any litigation in which it or any of its subsidiaries or affiliates is, or may become, a party; provided, however, that Executive shall not be required to provide information or assistance with respect to any litigation between the Executive and the Employer, or any of its affiliates.

6. Section 280G Cut-Back. Notwithstanding anything in this Agreement to the contrary, if the Cash Payment contained in Section 2 of this Agreement provided for in this Agreement, together with any other payments which the Executive has the right to receive from ESSA, ESSA Bank, and the Company, or any corporation which is a member of an “affiliated group” (as defined in IRC Section 1504(a), without regard to IRC Section 1504(b)) of which ESSA, ESSA Bank, and the Company is a member, would constitute an “excess parachute payment” (as defined in IRC Section 280G(b)(2)), payments pursuant to this Agreement shall be reduced to the extent necessary to ensure that no portion of such payments will be subject to the excise tax imposed by IRC Section 4999. Any determination required under this Section 6 shall be made by ESSA, ESSA Bank, and the Company and their respective tax advisors, whose determination shall be conclusive and binding upon the Executive.

7. IRC Section 409A Compliance. The intent of the parties is that payments under this Agreement either be exempt from or comply with Section 409A of the IRC and the Treasury Regulations and guidance promulgated thereunder and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith.

9. Effectiveness. Notwithstanding anything to the contrary contained herein, this Agreement shall be subject to consummation of the Merger in accordance with the terms of the Merger Agreement, as the same may be amended by the parties thereto in accordance with its terms.

Exhibit A

General Release of Claims

I understand that if I execute this General Release of Claims (this “Release”) and allow it to become effective, and otherwise comply with the terms of the Settlement and Non-Competition Agreement to which this Release is attached (the “Settlement Agreement”), ESSA Bank & Trust (“ESSA Bank”), a wholly-owned subsidiary of ESSA Bancorp, Inc. (“ESSA”) will pay me (or cause me to be paid) the Cash Payment as defined in the Settlement Agreement. Capitalized terms not defined herein shall be defined as in the Settlement Agreement. In consideration of the Cash Payment, I agree to the following:

On behalf of myself and my representatives, agents, heirs, executors, administrators, successors and assigns, I release and forever discharge the Company, ESSA, and ESSA Bank and each of their respective past, present, or future parents, subsidiaries, affiliates, and related entities, and all of their respective predecessors, successors, assigns, representatives, agents, counsel, insurers, members, officers, trustees, directors and employees (whether past, present or future) (all of the foregoing collectively, are referred to as the “Releasees”) from any and all claims, complaints, causes of action, demands, damages and suits that I have or may have for any reason whatsoever, in law or in equity, against any one or more of the Releasees arising out of or in connection with any event, transaction or matter occurring or existing on or before the date I execute this Release, whether based upon statutory claim, common law, contract (including but not limited to the Employment Agreement and any other employment-related agreement), tort, public policy or other basis, whether known or unknown, direct or indirect, absolute or contingent, including without limitation any claims arising under or related to any federal, state, local or other law or ordinance concerning civil rights, discrimination, retaliation, labor, employment or other matter, any claims related to my employment and any claims for attorneys’ fees, wages, salary, severance, bonus(es), compensation, other sums of money or payments, leave, benefits or any other obligation or liability whatsoever. I acknowledge that whether or not I execute this Release, the Company, ESSA and ESSA Bank have each paid me all compensation owed to me through the date I sign this Release other than the Cash Payment. I acknowledge and agree that the Cash Payment is sufficient consideration for the Release and I am not entitled to the Cash Payment if I do not sign the Release or allow it to become effective.

I understand that this is a GENERAL RELEASE and intend that it shall discharge the Releasees to the maximum extent permitted by law. For example, this Release waives any claims under the Age Discrimination in Employment Act, the Older Workers Benefit Protection Act, Title VI of the Civil Rights Act, Title VII of the Civil Rights Act, Title IX of the Civil Rights Act, the Equal Pay Act, the Americans with Disabilities Act, the Rehabilitation Act, the Civil Rights Act of 1866, the Family and Medical Leave Act, the Employee Retirement Income Security Act, the National Labor Relations Act, the Pennsylvania Human Relations Act, the Pennsylvania Whistleblower Act, all as amended, and any similar state, county or city ordinances. I represent that I have not filed, and agree not to file, any lawsuit or other action seeking monetary or other relief for me based on any claims lawfully released in this Agreement.

6

This Release does not limit any right to the extent it cannot be limited by private agreement. For example, this Release does not prohibit me from challenging its validity, or seeking unemployment compensation or workers’ compensation benefits, or from filing a charge with, providing information to, or participating in an investigation or proceeding conducted by a government agency (such as the Equal Employment Opportunity Commission or the U.S. Securities and Exchange Commission) authorized to enforce laws against unlawful conduct, but it does prohibit me from seeking, recovering, or accepting monetary payments or individual relief for me connected to any such agency or other action related to claims that are lawfully released in this Release. To the maximum extent permitted by law, I waive any and all rights to recover and will not accept, any monetary or other relief for me concerning the claims lawfully released in this Agreement.

(i) solicit, offer employment to, or take any other action intended (or that a reasonable person acting in like circumstances would expect) to have the effect of causing any officer or employee of ESSA or ESSA Bank or any of its affiliates to terminate his or her employment and accept employment or become affiliated with, or provide services for compensation in any capacity whatsoever to, any business whatsoever that competes with the business of ESSA, ESSA Bank, or any of their affiliates or has headquarters or offices within 50 miles of the locations in which ESSA, ESSA Bank or their affiliates have business operations or has filed an application for regulatory approval to establish an office;

(ii) become an officer, employee, consultant, director, independent contractor, agent, sole proprietor, joint venturer, greater than 5% equity-owner or stockholder, partner or trustee of any savings bank, savings and loan association, savings and loan holding company, credit union, bank or bank holding company, insurance company or agency, any mortgage or loan broker or any other entity competing with ESSA, ESSA Bank or their affiliates in the same geographic locations where ESSA, ESSA Bank or their affiliates have material business interests; or

(b) Executive shall, upon reasonable notice, furnish such information and assistance to the Employer and/or its affiliates, as may reasonably be required by the Employer and/or its affiliates, in connection with any litigation in which it or any of its subsidiaries or affiliates is, or may become, a party; provided, however, that Executive shall not be required to provide information or assistance with respect to any litigation between the Executive and the Employer, or any of its affiliates.

Any determination required under this Section 6 shall be made by ESSA, ESSA Bank, and the Company and their respective tax advisors, whose determination shall be conclusive and binding upon the Executive.

7. IRC Section 409A Compliance. The intent of the parties is that payments under this Agreement either be exempt from or comply with Section 409A of the IRC and the Treasury Regulations and guidance promulgated thereunder and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. A termination of employment, as used in this Agreement, shall mean a Separation from Service within the meaning of Section 409A of the IRC.

Exhibit A

General Release of Claims

I understand that if I execute this General Release of Claims (this “Release”) and allow it to become effective, and otherwise comply with the terms of the Settlement and Non-Competition Agreement to which this Release is attached (the “Settlement Agreement”), ESSA Bank & Trust (“ESSA Bank”), a wholly-owned subsidiary of ESSA Bancorp, Inc. (“ESSA”) will pay me (or cause me to be paid) the Cash Payment as defined in the Settlement Agreement. Capitalized terms not defined herein shall be defined as in the Settlement Agreement. In consideration of the Cash Payment, I agree to the following:

On behalf of myself and my representatives, agents, heirs, executors, administrators, successors and assigns, I release and forever discharge the Company, ESSA, and ESSA Bank and each of their respective past, present, or future parents, subsidiaries, affiliates, and related entities, and all of their respective predecessors, successors, assigns, representatives, agents, counsel, insurers, members, officers, trustees, directors and employees (whether past, present or future) (all of the foregoing collectively, are referred to as the “Releasees”) from any and all claims, complaints, causes of action, demands, damages and suits that I have or may have for any reason whatsoever, in law or in equity, against any one or more of the Releasees arising out of or in connection with any event, transaction or matter occurring or existing on or before the date I execute this Release, whether based upon statutory claim, common law, contract (including but not limited to the Employment Agreement and any other employment-related agreement), tort, public policy or other basis, whether known or unknown, direct or indirect, absolute or contingent, including without limitation any claims arising under or related to any federal, state, local or other law or ordinance concerning civil rights, discrimination, retaliation, labor, employment or other matter, any claims related to my employment and any claims for attorneys’ fees, wages, salary, severance, bonus(es), compensation, other sums of money or payments, leave, benefits or any other obligation or liability whatsoever. I acknowledge that whether or not I execute this Release, the Company, ESSA and ESSA Bank have each paid me all compensation owed to me through the date I sign this Release other than the Cash Payment. I acknowledge and agree that the Cash Payment is sufficient consideration for the Release and I am not entitled to the Cash Payment if I do not sign the Release or allow it to become effective.

I understand that this is a GENERAL RELEASE and intend that it shall discharge the Releasees to the maximum extent permitted by law. For example, this Release waives any claims under the Age Discrimination in Employment Act, the Older Workers Benefit Protection Act, Title VI of the Civil Rights Act, Title VII of the Civil Rights Act, Title IX of the Civil Rights Act, the Equal Pay Act, the Americans with Disabilities Act, the Rehabilitation Act, the Civil Rights Act of 1866, the Family and Medical Leave Act, the Employee Retirement Income Security Act, the National Labor Relations Act, the Pennsylvania Human Relations Act, the Pennsylvania Whistleblower Act, all as amended, and any similar state, county or city ordinances. I represent that I have not filed, and agree not to file, any lawsuit or other action seeking monetary or other relief for me based on any claims lawfully released in this Agreement.

6

This Release does not limit any right to the extent it cannot be limited by private agreement. For example, this Release does not prohibit me from challenging its validity, or seeking unemployment compensation or workers’ compensation benefits, or from filing a charge with, providing information to, or participating in an investigation or proceeding conducted by a government agency (such as the Equal Employment Opportunity Commission or the U.S. Securities and Exchange Commission) authorized to enforce laws against unlawful conduct, but it does prohibit me from seeking, recovering, or accepting monetary payments or individual relief for me connected to any such agency or other action related to claims that are lawfully released in this Release. To the maximum extent permitted by law, I waive any and all rights to recover and will not accept, any monetary or other relief for me concerning the claims lawfully released in this Agreement.

This Release is governed by and construed in accordance with the laws of the Commonwealth of Pennsylvania without regard to its conflict of laws provisions.

I acknowledge that I have been given at least forty-five (45) calendar days from the date I received this Release to consider, execute, and return it to Tom Grayuski, Senior Vice President, Chief Human Resources Officer at ESSA Bank & Trust, 200 Palmer Street, Stroudsburg, PA 18360, and that I must sign it as of the eighth (8^th) day prior to the Closing Date, which is currently anticipated to be [INSERT] (the “Required Execution Date”). I will be provided with the final Required Execution Date once the Closing Date is finalized and at least ten days prior to the Closing Date. I acknowledge that I am advised herein to consult an attorney about this Release prior to executing it. I acknowledge and fully understand that I am not entitled to Cash Payment from the Company unless I sign this Release as of the Required Execution Date, provided that this Release is provided to me at least ten days prior to the Closing Date, and I do not revoke this Release. For a period of seven (7) calendar days following my execution of this Release, I may revoke this Release by delivering a written notice of such revocation to Tom Grayuski, Senior Vice President, Chief Human Resources Officer at ESSA Bank & Trust, 200 Palmer Street, Stroudsburg, PA 18360 , whose contact information is listed above, in which case this Release shall be null and void and of no force or effect on either me or the Company, and I will not receive any Cash Payment. This Release will not become effective or enforceable, and I will not be eligible to receive the Cash Payment, until this seven (7) day revocation period expires without me revoking this Release (the next day after such period expires is the “Effective Date”). I also acknowledge that a) the Required Execution Date is at least forty-five (45) days following my receipt of this Release and b) I have also received an “Age Discrimination in Employment Act Disclosure,” attached as Exhibit I, that contains information regarding (i) any class, unit, or group of individuals covered by the Company’s reduction-in-force program that includes my termination of employment (the “Program”), any eligibility factors for the Program, and any time limits applicable to the Program; and (ii) the job titles and ages of all individuals selected for the Program, and the ages of all individuals in the same job classification or organizational unit who are not selected for the Program.

7

I acknowledge that at the time I sign this Release, I have returned or will return upon my termination date, to the Company all of its equipment, property, and files in my possession, custody, or control, including but not limited to all files and documents (whether in paper or other tangible form, or in electronic form), provided that I may retain my own personal compensation, financial, and benefits information.

By signing this Release, I acknowledge that I have had the opportunity to consult with an attorney should I choose to do so, that I fully understand the terms of this Release and that I voluntarily agree to them without coercion, duress, or undue influence. If I agree to the terms of this Release, I will return the executed Release to Tom Grayuski, Senior Vice President, Chief Human Resources Officer at ESSA Bank & Trust as described above.

The combined company is expected to have approximately $8 billion in total assets, $7 billion in total deposits, and $6 billion in total loans.

The transaction consideration is all common stock and is presently valued at approximately $214 million in the aggregate, or approximately $21.10 per ESSA share, based upon the 10-day volume weighted average stock price (VWAP) of $24.69 for CNB common stock as of January 8, 2025.

ESSA shareholders will receive 0.8547 shares of CNB common stock for each outstanding share of ESSA common stock.

Headquartered in Stroudsburg, PA, ESSA operates 20 community offices throughout the Lehigh Valley, Greater Pocono, Scranton/Wilkes-Barre, and suburban Philadelphia areas. Following completion of the merger, ESSA Bank & Trust will operate as ESSA Bank, a division of CNB Bank (“ESSA Bank” or “ESSA division”), operating within its existing geographic footprint. CNB anticipates accelerating growth in the greater Lehigh Valley and Scranton/Wilkes-Barre markets utilizing its commercial-oriented playbook and expanding fee-based business lines, bolstering its presence across Pennsylvania.

Olson, current President, CEO, and Director of ESSA, Robert C. Selig Jr., current Chairman of the Board of ESSA, and Daniel J.

“We are excited to partner with ESSA which shares such a strong banking tradition with CNB. This combination aligns two high performing banks with an exceptional commitment to client-focused services for its customers and financial support to sustain the economic vitality of the communities in which they operate,” announced Michael D. Peduzzi, President and CEO of CNB. “There are many similarities between the markets of ESSA and our existing CNB locations, as well as with our personal approach to banking. We understand the needs of the commercial, retail, and wealth management customers in these markets and look forward to providing the ESSA division with the support and assistance they need to continue to grow and thrive.”

Mr. Olson added, “CNB is a powerful partner for our bank that closely mirrors our culture and values, making the transaction a natural fit. CNB’s multi-state, multi-brand business model fosters our entrepreneurial spirit, and continues our commitment and presence in eastern Pennsylvania. Leveraging CNB’s infrastructure and robust capital position, suite of banking products, and combined larger lending limit, will further enhance our community banking model, and continue to serve our new and existing customers extremely well.”
