On track with executing our Strategy – Expanding Our Reach : • Continued focus on growing the Wealth business. • Transitioning from Multifamily to C&I and relationship based residential lending. • CRE, including Multifamily, focused on cross - sell to enhance client profitability. Pricing/profitability modeling has been incorporated bank - wide to support this. Strategic Update 8 Our Plan has created / will continue to create shareholder value: • We continue to add considerable “large bank” talent. • Wealth Division Assets Under Administration has grown over $1 billion or 44% over the last three years. • Enviable revenue mix – 22% non interest income, largely driven by Wealth Management (16%). • We continue to deliver considerable positive operating leverage. • Loan composition has evolved from transaction based residential to commercial. • Total C&I loans have grown nearly $400 million or 346% over the past three years. • Positive stock momentum.

• Multi agency CRE guidance issued in December has implications as it relates to our 700% CRE concentration and recent high rate of growth in Multifamily loans. • Certain risk management expense spends are being pulled forward in 2016 – (approximately $2MM , estimated cost ). • We anticipate $4MM in near term of higher FDIC premiums. • Of these $6MM costs in 2016, approximately $5MM will be “transitory”. • Market volatility will likely have an adverse impact on 2016 wealth revenue and earnings. Looking Forward to 2016 We Have Some Headwinds 9

We remain on course and are focused on enhancing shareholder value: • Our Strategy – Expanding Our Reach – remains unchanged; Multifamily loans have reached their peak at 50% of total loans; a gradual slow down is underway. • C&I , Relationship based Mortgage Lending, and Wealth Management businesses have gained considerable traction; these are areas of growth and value creation consistent with our Strategic plan. • Wealth Management related M&A is a focus. • Organic growth in wealth and C&I remains strong. • Our CRE concentration is primarily in low - risk Multifamily (rent regulated/workforce housing). Multifamily growth has been used as an effective method to achieve scale and fund infrastructure growth in C&I Lending and Wealth Management. • Asset quality remains strong; no multifamily delinquencies as of 12/31/2015; total delinquent loans, 30 - 89 days past due, totaled only $2.1 million; NPA ratio totaled 22 bps at year end. Despite Short Term Headwinds, We Will Continue To Create Shareholder Value 10

Retail, from branches and mobile • Demand deposits, money markets and CD’s. Business • Operating accounts and business money market. • Treasury Services platform to support client defined requirements. Wealth clients • Deposit solutions as part of comprehensive wealth management platform. Reciprocal insured deposits • In partnership with a third party provider, FDIC insured accounts up to $22 million for business, retail and wealth accounts. • Reported as a brokered deposit pursuant to regulatory specifications. However, we consider these deposits to be in - market customer deposits, as distinguished from traditional out - of - market brokered deposits, since they originate from our customers . Diversified Customer Funding Sources 23

Brokered • Long dated (up to 10 years) time deposits for interest rate risk management; tenors not available from retail sources. • Money market, provided by the reciprocal deposit partner, from conduit pools; provides supplemental liquidity and a basis for efficient swaps for interest rate risk management. Listing Service Time Deposits • Multiple service providers to access the listing service time deposit market; long dated time deposits from a diverse set of institutional counterparties; supports interest rate risk management. Secured funding • Federal Home Loan Bank – Sufficient collateral pledged to qualify for maximum capacity (30% of assets); used for term borrowing for interest rate risk management and short term funding as needed. • Federal Reserve Bank – Over $100 million of collateral pledged to cover daylight over - draft capacity and late day intermittent borrowing, as needed. Other Diversified Funding Sources 24

• We manage to shorter duration / adjustable rate assets. • Created a loan participation program. • Customer deposit relationships strong. • Focus CDs on medium to longer term where pricing is more efficient. • Disciplined interest rate SWAP program to extend liability duration (cash flow hedges). • Offer loan level interest rate SWAP product to select clients; the effect shortens asset duration (fair value hedges). • In an immediate and sustained 100 basis point increase in market rates at 12/31/2015, net interest income for year 1 would increase approximately 2%, when compared to a flat interest rate scenario. In year 2, this sensitivity improves to an increase of approximately 4%, when compared to a flat interest rate scenario. Interest Rate Risk Management 25
