(INCLUDING WAIVER OF CLAIMS UNDER THE AGE

DISCRIMINATION IN EMPLOYMENT ACT OF 1967, AS AMENDED)

This Confidential Separation Agreement and General Release (“Release Agreement”) is entered into on the first date set forth below by and among Robert M. Garst (hereinafter referred to as “Executive”), Riverview Financial Corporation (“Corporation”) and Riverview Bank (hereinafter referred to as the “Bank”), collectively referred to as the “Parties.”

BACKGROUND

Executive is party to the “Second Amended and Restated Executive Employment Agreement,” dated January 24, 2012 (the “Employment Agreement) with and among the Corporation and the Bank, pursuant to which Executive has been employed by the Bank in the position of Chief Executive Officer. The Parties have agreed that Executive’s employment with the Bank will be terminated in accordance with Section V(4) of the Employment Agreement, effective June 30, 2015 (the “Effective Date”). Pursuant to this Release Agreement, the Bank will provide Executive with separation and severance payments and benefits to which Executive would not otherwise be entitled. In exchange, Executive has agreed to a release of all claims that he may have against the Corporation and the Bank and the Releasees as defined in Paragraph 3, below.

NOW THEREFORE, in consideration of the mutual promises contained herein, and the releases, warranties and representations of Executive, the Parties, intending to be legally bound, AGREE as follows:

1. Payments and Benefits.

a. Separation Payment. Effective as of the Effective Date, Executive’s employment with the Bank as Chief Executive Officer will end pursuant to Section V(4) of the Employment Agreement. Executive shall receive a separation payment in the amount of One Million, Four Hundred Ten Thousand Dollars and No Cents ($1,410,000.00), less applicable taxes and withholdings (the “Separation Payment”), payable in twenty-four (24) equal monthly installments of Fifty-Eight Thousand Seven Hundred Fifty Dollars and No Cents ($58,750.00), less applicable taxes and withholdings, commencing on the Bank’s first normal pay date for executives following both the expiration of the seven day revocation period set forth in Paragraph 6(d), below, and the Effective Date of Executive’s termination.

b. Additional Severance Payment. The Bank agrees to pay Executive an additional severance payment in the amount of One Hundred Thousand Dollars and No Cents ($100,000.00) (the “Severance Payment”), less applicable taxes and withholdings, as a gross-up payment to offset certain anticipated income tax consequences that may be incurred by Executive as a result of the Separation Payment. The Severance Payment shall be payable in twenty-four (24) equal monthly installments of Four Thousand One Hundred Sixty-Six Dollars and Sixty-Six Cents ($4,166.66), less applicable taxes and withholdings, commencing on the

1

Bank’s first normal pay date for executives following both the expiration of the seven day revocation period set forth in Paragraph 6(d), below and the Effective Date of Executive’s termination.

c. The Separation and Severance Payments and benefits described in this Paragraph 1 shall only be offered and made if (i) Executive signs this Release Agreement and does not revoke this Release Agreement within the time period set forth under Paragraph 6(d), below, (ii) Executive cooperates in the Transition and Consultation outlined in Paragraph 4(c), below, and (iii) Executive complies with the other provisions of this Release Agreement.

d. Payment for Accrued Unused Paid Time Off. The Bank agrees to pay Executive for any accrued but unused paid time off through and ending the Effective Date.

e. Stock Options. The Bank agrees that Executive shall retain all stock options vested as of the Effective Date in accordance with the terms of the Amended and Restated 2009 Stock Option Plan of Riverview Financial Corporation (the “Plan”) and the Grants of Stock Options to Executive. In addition, Executive will continue to serve the Bank in the capacity of “Director Emeritus.” The Bank further agrees that in such capacity, Executive shall retain all currently unvested stock options awarded under the Plan and all Grants of Stock Options. Notwithstanding anything to the contrary contained in the Grants of Stock Options to Executive from the Corporation, the vesting schedule and the exercise rights under the Grants of Stock Options to Executive shall continue as if Executive’s employment had not been terminated on the Effective Date, and as if Executive had remained an employee of the Bank and the Company. A summary of Executive’s vested and unvested stock options as of June 30, 2015, is attached as Exhibit A. Following Executive’s termination from employment, Executive shall not be entitled to any additional award of stock options under the Plan.

f. Disability or Death. Executive’s disability or death following Executive’s termination of employment shall not affect Executive’s right, or if applicable, the right of Executive’s beneficiaries, to receive the Separation and Severance Payments and benefits described in this Release Agreement. In the event of Executive’s death following the Effective Date of his termination of employment, Executive’s beneficiaries, if any, shall be entitled to receive the balance of payments due, if any, under this Paragraph 1.

g. Bank Provided Automobile. The Bank shall, within thirty (30) days of the Effective Date of Executive’s termination of employment, transfer and deliver the title to the Bank automobile which the Executive uses at the time of the Effective Date into the Executive’s name, such that the automobile shall become the property of the Executive. The Bank shall provide Executive with an IRS Form 1099 for the assessed value of the automobile. Executive is responsible for assuming any and all costs and expenses associated with ownership of the Bank automobile and the transfer of the automobile into his name, including the cost of transfer of title, tags, registration and insurance.

2. Adequate Consideration. Executive agrees that (i) the consideration and payments made to him by the Bank pursuant to this Release Agreement represent the sole and

2

exclusive payments and undertakings to be provided to him; (ii) said payments include any and all outstanding and accrued compensation, wages, and benefits that may be due and owing Executive; (iii) that neither the Bank nor the Corporation have any further obligation to provide Executive with any compensation of any sort, or any non-monetary or monetary benefits in addition to that which is set forth in Paragraph 1, above; and (iv) the aforementioned Separation and Severance Payments and other benefits are in excess of what Executive otherwise would have been entitled to and constitute good and sufficient consideration for this Release Agreement.

3. Release and Waiver.

a. For and in consideration of the Bank’s and the Corporation’s promise to cause the payments and benefits to be made as set forth in Paragraph 1, above, Executive does hereby REMISE, RELEASE AND FOREVER DISCHARGE Riverview Financial Corporation, Riverview Bank, and their respective parent corporations, subsidiaries and affiliates, and all of the foregoing’s respective directors, officers, shareholders, employees, representatives, agents, attorneys, insurers, successors and assigns (“Releasees”) of and from any and all manner of actions and causes of action, suits, debts, liabilities, losses, damages, claims and demands whatsoever (which are otherwise subject to waiver) that Executive had, has or may have against any of the Releasees, whether sounding in contract, any form of tort or otherwise; whether at law or in equity; whether known or unknown; from prior to the commencement of Executive’s employment with any of the Releasees to the date of this Release Agreement.

Executive has been advised to consult with an attorney before signing this Release Agreement waiving his rights under the ADEA. Executive has had the opportunity to review this Release Agreement for twenty-one (21) days prior to signing it.
