A Diversified Loan Mix A diverse, high-quality loan portfolio provides additional balance to Northwest’s current portfolio mix. Our combined entity can capitalize on Northwest’s mortgage and home equity expertise in the Cleveland market and on LNB’s consumer lending expertise across Northwest’s vast footprint. Northwest’s size and capital strength will allow our Ohio team to increase their targeted loan size and gain access to a base of businesses with higher borrowing needs. The deal premium as a percentage of loans is just 8.8%. In this environment, loans are as important as deposits. LNB’s loan to deposit ratio is 87.3%. 10 September 30, 2014 Northwest (loans in millions) % of Total Residential RE 2,519.4 41.6% Home Equity 1,071.5 17.7% Consumer 238.7 4.0% Commercial RE 1,787.9 29.5% Commercial 437.4 7.2% 6,054.9 100% Portfolio Yield 4.78% LNB (loans in millions) % of Total Residential RE 70.9 7.7% Home Equity 125.3 13.6% Consumer 227.2 24.6% Commercial RE 413.6 44.8% Commercial 85.5 9.3% 922.5 100% Portfolio Yield 3.91% Combined (loans in millions) % of Total Residential RE 2,590.3 37.1% Home Equity 1,196.8 17.2% Consumer 465.9 6.6% Commercial RE 2,201.5 31.6% Commercial 522.9 7.5% 6,977.4 100% Portfolio Yield 4.66% Northwest loan total is grossed up by undisbursed loan commitments and reduced by deferred loan costs.

Assuming cost saves of 28%, the efficiency ratio of the Ohio Region of Northwest after the merger would be approximately 51%, thereby lowering Northwest’s current efficiency ratio of 65%.

Exceptional Market Potential Although not considered to be an in-market acquisition, LNB’s footprint is a contiguous market and a natural extension of our strongest market, northwest Pennsylvania, and is complemented by our existing four offices in northeast Ohio. LNB ranks in the top 3 in market share in 9 of its 12 markets. With the addition of LNB, Northwest’s Ohio Region will be the second largest of our eight geographic regions. The Cleveland/Akron/Canton combined statistical area has a population of 3.7 million people, representing 1.5 million households and is the 15th largest CSA in the country.* The Cleveland MSA has a diversified employment base led by manufacturing and service-based industries including health care. Employment statistics in the Cleveland MSA have improved greatly in recent years with unemployment down to 5.4% in Cleveland, 4.3% in Akron and 4.5% in Canton.** All counties within the Cleveland MSA reside within the Marcellus and Utica Shale footprint. The already strong ties between western Pennsylvania and eastern Ohio will continue to grow as their shared exposure to shale gas exploration further develops. 12 * Source: SNL ** Source: U.S. Bureau of Labor Statistics

Exceptional Market Potential The Cleveland/Akron/Canton area is experiencing a rebirth from a rust belt market to a center of brain gain. The area will always have a strong foundation in manufacturing and energy, particularly with the exploration of Marcellus and Utica Shale formations. LNB’s market area is home to several nationally acclaimed healthcare providers and an emerging technology and biotechnology sector. As a result, there is a tremendous infrastructure of private equity, legal and financial professionals. With a low cost of living and high quality of life, employers are attracting talent to the area. As a small metropolitan area, LNB’s market area is easy to navigate and yet has close access to two major airports and several regional airports. There are also NFL, NBA and MLB professional sports franchises, as well as five minor league teams. The area is also home to 68 colleges and universities. This vibrancy is not lost on the rest of the country, with Cleveland recently having been a candidate for both the Democratic and Republican National Conventions in 2016 and selected as the winner for the RNC. These factors have led to significant investment in the revitalization of the downtown area, which has had a halo effect on the entire region both economically and emotionally. 13
