Presidio was a full-service California state-chartered commercial bank headquartered in San Francisco with branches in Palo Alto, San Francisco, San Mateo, San Rafael, and Walnut Creek, California. The Presidio acquisition went a considerable way towards accomplishing Heritage’s strategic objective of a market footprint that fully surrounds the San Francisco Bay Area. The Walnut Creek Branches of Heritage and Presidio were consolidated in the Q1/2020 and the San Mateo branches of Heritage and Presidio are planned for consolidation in Q3/2020.

Coronavirus (COVID-19) ▪ The State of California and 7 Bay Area counties which account for all of the Bank’s market footprint, remains under a “Shelter-in-Place” order through at least May 31, 2020. Statewide initial jobless claims totaled over 4.2 million during the 8 weeks ending May 9, 2020. Since March 15, 2020, management has taken a number of steps to help protect the safety and well-being of our customers, employees and communities. ▪ ▪ ▪ ▪ Approximately 75% of staff working remotely. Established social distancing protocols within our bank premises and branches for both employees and customers. All branches remain open to serve our customers and communities but with reduced hours (10am-4pm), “Maximum Two Clients at a Time” entry and “Marked 6 Foot Spacing” to ensure “Social Distancing”. In compliance with Health Directives, all branch personnel (and customers, if required), have been supplied with masks, gloves and sanitizer. Increased compensation for personnel whose roles require that they serve customers in a branch. ▪ ▪ ▪ ▪ Following the passage of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) in March 2020, the Bank immediately participated in the Small Business Administration (“SBA”) Paycheck Protection Program (“PPP”). ▪As of May 14, 2020, the Bank had processed 1,435 PPP loan applications and outstanding PPP loan balances were approximately $325 million. In keeping with guidance from regulators, and in response to customer’s needs, the Bank is actively working with COVID-19 affected borrowers to defer their payments and interest: ▪As of May 14, 2020, we had received 384 payment deferral requests. The net amount of potential deferrals approved or in process was $222 million, or 8.9%, of our loan portfolio.

Adoption of CECL ▪ In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, a methodology that reflects the current expected credit losses (“CECL”) for the life-of-loan, and requires consideration of a broader range of reasonable and supportable information to estimate future credit loss estimates including an estimate of expected credit losses for held-to-maturity debt securities. The Company adopted Topic 326 on January 1, 2020. The following table shows the results of adopting CECL for the first quarter of 2020: ▪ (i n $000’s ) Allowance for loan losses at December 31, 2019 Day 1 adjust ment impact of adopt ing T opic 326 Net (charge-offs) during t he period Impact of port folio changes during t he period Impact of CECL economic forecast and assumpt ion changes Allowance for credit losses on loans at March 31, 2020 $ 23,285 8,570 (422) 1,216 12,054 $ 44,703 ▪ The Day 1, $8.6 million adjustment primarily relates to loan portfolios acquired in recent acquisitions that under the previous methodology were covered by purchase discounts and is largely recorded, net of tax of $2.4 million, as a $6.1 million reduction to retained earnings effective January 1, 2020. The $13.3 million provision in the first quarter of 2020 was driven primarily by a significantly deteriorated economic outlook resulting from the Coronavirus pandemic. For a detailed discussion of the Company’s adoption of CECL, please refer to Form 10Q dated March 31, 2020, page 46, filed with the SEC on May 8, 2020. ▪ ▪ 12
