Risks Relating to the Coronavirus (COVID-19) Outbreak In March 2020, the World Health Organization declared the coronavirus (COVID-19) outbreak a pandemic and the United States declared a national emergency. Global and national health concerns relating to the coronavirus outbreak have been weighing on the local, national and global economic environments, and the outbreak has significantly increased economic uncertainty. The outbreak has resulted in authorities implementing numerous measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter in place orders, and business shutdowns. These measures have not only negatively impacted consumer and business spending habits, they have also adversely impacted and may further impact VABK and FBSS's workforces and operations and the operations of their customers, vendors and business partners. These measures may remain in place for a significant period of time and they are likely to continue to adversely affect the businesses, results of operations and financial condition of VABK and FBSS. The bank regulatory agencies and various governmental authorities are urging financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations because of the effects of COVID-19. Loan forbearances and other measures have been and will continue to be taken to assist affected customers and businesses, which may have an adverse impact on results of operations and financial condition. VABK's and FBSS's loans to particular businesses, such as restaurants, hotels and contractors, as well as to people working in those industries, may be particularly subject to adverse developments. Disruptions to customers could result in increased delinquencies, defaults, foreclosures and losses on loans, negatively impact regional economic conditions, result in declines in local loan demand, liquidity of loan guarantors, loan collateral (particularly in real estate), loan originations and deposit availability. The spread of the coronavirus has also caused VABK and FBSS to modify their business practices (including employee travel, employee work locations, and cancellation of physical participation in meetings, events and conferences), and VABK and FBSS may take further actions as may be required by government authorities or that they determine are in the best interests of their employees, customers and business partners. There is no certainty that such measures will be sufficient to mitigate the risks posed by the virus or otherwise be satisfactory to government authorities. The extent to which the coronavirus outbreak impacts VABK's and FBSS's business, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration and spread of the outbreak, its severity, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. Even after the coronavirus outbreak has subsided, VABK and FBSS may continue to experience materially adverse impacts to their businesses as a result of its economic impact, including any recession that has occurred or may occur in the future. There are no comparable recent events which may provide guidance as to the effect of the spread of the coronavirus and a global pandemic, and, as a result, the ultimate impact of the coronavirus outbreak or a similar health epidemic is highly uncertain and subject to change. The full extent of the impact on VABK's and FBSS's businesses, operations or the economy as a whole is not yet known. However, the effects could have a material impact on results of operations, and VABK and FBSS will continue to monitor the coronavirus situation closely.

Legal Disclaimer Cautionary Note Regarding Forward-Looking Statements This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to, statements about (i) the benefits of a merger between VABK and FBSS, including future financial and operating results, cost savings, enhancements to revenue and accretion to reported earnings that may be realized from the merger; (ii) VABK’s and FBSS’s plans, objectives, expectations and intentions and other statements contained in this presentation that are not historical facts; and (iii) other statements identified by words such as “may”, “assumes”, “approximately”, “will”, “expects”, “anticipates”, “intends”, “plans”, “believes”, “seeks”, “estimates”, “targets”, “projects”, or words of similar meaning generally intended to identify forward-looking statements. These forward- looking statements are based upon the current beliefs and expectations of the respective management of VABK and FBSS and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond the control of VABK and FBSS. In addition, these forward-looking statements are subject to various risks, uncertainties and assumptions with respect to future business strategies and decisions that are subject to change and difficult to predict with regard to timing, extent, likelihood and degree of occurrence. As a result, actual results may differ materially from the anticipated results discussed in these forward-looking statements because of possible uncertainties. The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements: (1) the businesses of VABK and FBSS may not be combined successfully, or such combination may take longer, be more difficult, time-consuming or costly to accomplish than expected; (2) the expected growth opportunities or cost savings from the merger may not be fully realized or may take longer to realize than expected; (3) deposit attrition, operating costs, customer losses and business disruption following the merger, including adverse effects on relationships with employees and customers, may be greater than expected; (4) the regulatory approvals required for the merger may not be obtained on the proposed terms or on the anticipated schedule; (5) the shareholders of VABK or FBSS may fail to approve the merger; (6) economic, legislative or regulatory changes, including changes in accounting standards, may adversely affect the businesses in which VABK and FBSS are engaged; (7) the interest rate environment may further compress margins and adversely affect net interest income; (8) results may be adversely affected by continued diversification of assets and adverse changes to credit quality; (9) competition from other financial services companies in VABK’s and FBSS’s markets could adversely affect operations; (10) an economic slowdown could adversely affect credit quality and loan originations; (11) the COVID-19 pandemic is adversely affecting VABK, FBSS, and their respective customers, employees and third-party service providers; the adverse impacts of the pandemic on their respective business, financial position, operations and prospects have been material, and it is not possible to accurately predict the extent, severity or duration of the pandemic or when normal economic and operation conditions will return; and (12) other factors that may affect future results of VABK and FBSS, including: changes in asset quality and credit risk; the inability to sustain revenue and earnings growth; changes in interest rates and capital markets; inflation; customer borrowing, repayment, investment and deposit practices; the impact, extent and timing of technological changes; capital management activities; and other actions of the bank regulatory agencies and legislative and regulatory actions and reforms. Additional factors that could cause actual results to differ materially from those expressed in the forward-looking statements are discussed in VABK’s and FBSS’s reports (such as Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K) filed with the SEC and available on the SEC’s Internet site (http://www.sec.gov). Risks Related to the SBA PPP Loan Program VABK and FBSS are participating lenders in the Paycheck Protection Program (“PPP”), a loan program administered through the Small Business Administration (“SBA”), which was created to help eligible businesses, organizations and self-employed persons fund their operational costs during the COVID-19 pandemic. Under this program, the SBA guarantees 100% of the amounts loaned under the PPP. VABK and FBSS may be exposed to credit risk on PPP loans if a determination is made by the SBA that there is a deficiency in the manner in which the loan was originated, funded, or serviced. If a deficiency is identified, the SBA may deny its liability under the guaranty, reduce the amount of the guaranty, or, if it has already paid under the guaranty, seek recovery of any loss related to the deficiency. Financial institutions have experienced litigation related to their process and procedures used in processing applications for the PPP. If VABK or FBSS were to be subject to any such litigation, such litigation could have a material adverse impact on the companies' businesses, financial conditions and results of operations. VABK and FBSS caution that the foregoing list of factors is not exclusive. All subsequent written and oral forward-looking statements concerning the proposed transaction or other matters attributable to VABK or FBSS or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above. VABK and FBSS do not undertake any obligation to update any forward-looking statement to reflect circumstances or events that occur after the date the forward-looking statements are made.
