Asset Quality

Reserve & Charge-Offs History 25 Northwest's actual losses have historically been much lower than its peer group. Conservative underwriting and a commitment to working with our borrowers, have kept our losses at comparatively low levels during the current economic crisis. See Appendix for Peers; Peer data based on SNL Financial as February 3, 2010 (CHART) Net Charge-Offs as a % of Avg Loans (CHART)

Loan Breakdown By State 27 Dollars in thousands Loans by State (based on borrowers' residence) at December 31, 2009 90% of our loans are located in our core market of Pennsylvania and New York.

Average Mortgage Loan Balance and LTV Northwest's average mortgage balance is extremely low which enables borrowers to continue making their payments during times of economic challenge. Conservative underwriting has ensured that Northwest's mortgage customers have a significant equity position in their homes. $3.3 billion of our $5.3 billion in gross loans are residential mortgage and home equity loans. 28

Strategic Direction

Investment of Proceeds of Second-Step Funds temporarily invested in overnight deposits Difficult environment to improve yield Want to stay short-term or variable rate Do not want to increase credit-risk exposure in investment portfolio Use funds to grow loan portfolio while being mindful of interest rate risk. Leveraging of Proceeds of Second-Step Continue organic growth strategies - especially focused on improving loan and deposit mix Continue strategic goal of opening five de novo offices a year Maintain a disciplined acquisition strategy Investment and Leveraging of Second Step 35

Disciplined Acquisition Strategy 36 Opportunity in our market areas: In PA, NY, OH and MD - approximately 170 public and private banks and thrifts with assets between $300 million and $3 billion On a selective basis, we would consider: whole bank acquisitions FDIC assisted transactions branch divestitures

Disciplined Acquisition Strategy 37 Acquisition criteria Strategic first preference is for acquisitions within our current markets secondarily, we prefer acquisitions in contiguous or near contiguous market areas prefer banks that add complementary products and services, diversified deposit mixes and strong branch networks

Investment Opportunity

Investment Opportunity in Northwest 39 Things we plan to do: Continuing our evolution of becoming more bank-like Continue our disciplined acquisition strategy in our current or adjacent markets Focus on self-originated small business and commercial credits vs. residential loans Dividends and stock buybacks Things we don't plan to do: Originate subprime or alt-a loans Originate option ARMs Lend outside of our market area Purchase participations in commercial or commercial real estate loans Change our fundamental business plan Experienced management team Conservative credit culture Substantial growth opportunities in attractive markets Attractive price given our strong capital position
