GURGOVITS:

     Thank you, Bartley. Good morning everyone and welcome to FNB’s conference call to discuss our merger with Omega Financial Corporation. A copy of the presentation we will be referencing this morning is available on our Web site in the Investor and Analyst Presentations section ofwww.fnbcorporation.com. With me today is Brian Lilly, our Chief Financial Officer.

     This morning, FNB Corporation and Omega Financial Corporation jointly announced the signing of a definitive agreement and plan of merger. The transaction is valued at approximately $393 million. Omega Financial Corporation is the holding company for Omega Bank, one of the largest independent community banks headquartered in central Pennsylvania, with roots in the state dating back to the early 1900s. I’d like to spend a moment discussing our rationale for this transaction and some of the key terms. I will then turn the call over to Brian who will address the potential impact on our financial results. After which, we would be happy to take any questions from analysts and investors.

4

     There are four key reasons we are excited to announce this transaction.First, the addition of Omega’s franchise moves us into several attractive areas in the central part of Pennsylvania, in which we currently have no presence and fills in our existing network. The fill-in of our footprint will allow us to provide a larger service area for our customers throughout the state. The move into a faster growing market in the central part of Pennsylvania is also consistent with our stated expansion strategy.Second, Omega has a complementary business mix that emphasizes diversifying their revenue stream. Their fee businesses are solid revenue streams that fit naturally with our core banking activities and help us achieve our own revenue diversification goals.Third,regarding the low integration risk, key management personnel from Omega will be employed to assist in the integration and our experience successfully integrating past acquisitions will serve us well.Fourth, we view the terms of the transaction as financially compelling, as we are upholding our strict criteria of having acquisitions be accretive to cash earnings per share in the first full year after closing and not dilutive to capital. The acquisition is not only two percent accretive to our cash EPS in 2009 andimmediately accretive to our tangible book value per share by five percent, but also nicely above our cost of capital from an Internal Rate of Return (IRR) standpoint. As with any in-market transaction, we believe that there are a reasonable amount of cost savings to be realized. We have conservatively not projected any revenue synergies in our modeling, but believe that there will be these opportunities stemming from having employees of both companies possessing a larger product set to sell and cross-sell and a bigger balance sheet.

     For those of you not familiar with Omega, we provide some additional detail. We believe Omega’s 64 retail branches fit nicely in between the Pittsburgh and Harrisburg

5

regions of our existing footprint. The management team of Omega has ably penetrated its markets with a very strong share in seven of its top-ten markets.

     You can see that Omega’s markets are demographically attractive, providing us better growth opportunities.

     Their loan mix is also very complementary. I would point out that we view Omega’s loan portfolio as poised for solid growth in the coming years, as they have prudently run-off balances of certain loan categories acquired from a prior acquisition. For example, they have de-emphasized indirect auto lending and have now begun to sell their residential mortgage production into the secondary market. Omega has no direct exposure to the sub-prime lending markets in either its loan portfolio or through its mortgage loan joint-venture, Omega Financial Mortgage Solutions. Overall, we have spent a good deal of time reviewing Omega’s loans and are comfortable with its exposures.

     Omega also has a very attractive funding mix with non-interest demand deposits and overall total deposits of 16 percent and 90 percent, respectively, of its total funding. Omega’s low-cost core deposits total 94 percent of its total deposits.

     Regarding the deal terms, consideration will be structured as a 100 percent stock, tax free exchange for Omega’s shareholders. The FNB board will be expanded with the addition of three directors from Omega. Donita Koval, Omega’s current President and CEO has agreed to join FNB and will become CEO of our new Omega region.

     At this point, let me turn the presentation over to Brian who will provide some additional details on the financial impact of the transaction. Brian?

LILLY:

     Thank you Steve and good morning everyone.

     We have included the key modeling assumptions in the materials on our Web site so I won’t repeat those in detail now. But, I do want to touch on a few points. Namely: transaction pricing, the expected earnings per share accretion/dilution and capital impacts and, lastly, credit quality.

     As Steve mentioned, the financial profile of this transaction is compelling. Starting with the pricing metrics, we note that the earnings multiples are fair for Omega’s shareholders and attractive relative to the median levels for comparable transactions. The 16.1 times our 2008 estimate of Omega’s earnings is enhanced to an even more attractive 11.1 times after factoring in the 30 percent cost savings on a fully-phased in basis. The Internal Rate of Return of nearly 15 percent is well-above our cost of capital.

     As many of you know, during our due diligence process we build a financial model from the ground up based on what we believe to be the go forward opportunities. We believe that we have a very realistic view of the earnings contribution from the Omega franchise. In many ways this is an opportune time for this partnership. The Omega team has worked their way through a challenging merger over the past few years and has positioned the Company in good markets with a strong balance sheet and an attractive business mix. In simple financial terms, our go forward earnings view, before cost savings and transaction accounting, is similar to the I/B/E/S consensus with approximately 7 percent earnings growth. I should note for you that we did enhance the 2008 earnings estimate over the current Omega street estimates by approximately six

7

cents for a change in the Pennsylvania Share tax laws. This change reduces the capital stock tax expense beginning in 2008 and forward.

     We are very pleased with the strong accretion to cash earnings per share. With regard to the GAAP EPS impacts, it is important to consider the EPS accretion/dilution coupled with the strategic benefits to our capital position. Let me explain.

     First, Omega is unique, as they maintain an exceptionally strong capital position, as evidenced by a tangible equity ratio in excess of 10 percent. Next, given the current operating environment for banking and the benefits of additional strategic flexibility, we concluded that additional capital was attractive. To put this in context, were we to raise approximately $50 million in equity capital, we calculate the dilution from the additional capital to be over 2.5 percent on earnings.

     Now, in the materials, you will see that the 2008 GAAP EPS dilution of 2.7 percent is almost entirely driven by the benefit of increasing the tangible equity ratio over 70 basis points to almost 5 and one-half percent at closing. Further, the 2010 GAAP EPS accretion increases to approximately 3% if we had not decided to take advantage of Omega’s strong capital position for the benefit of the combined shareholder base.

     Said another way, if this was a capital neutral transaction structure to FNB, the GAAP accretion would have turned positive within the first year with 2009 being in excess of 2 percent accretive and 2010 in excess of 3 percent.

     Clearly, we are pleased with the expected earnings accretion from the merger. And we view the enhancements to our capital position, with the ability to earn back the

8

earnings dilution from the additional capital over a short period of time, as an additional unique benefit to this merger.

     Lastly, let me touch on the credit quality metrics of the combined company. From a high-level perspective, the credit metrics will be mixed relative to our historically strong standards. Starting out, non-performing loans of the combined company will be higher. The primary factor contributing to this increase is one large non-accruing commercial credit that Omega has been working through.

     In terms of the overall credit quality, we have conducted our loan due diligence and believe that we have appropriately modeled the impacts. As with past acquisitions, we will work with Omega’s management to compliment their efforts in dealing with a few problem credits.

     In summary, we believe that we have built our operating plans on realistic and attainable assumptions. As an additional benefit, we have enhanced the capital position of the combined company. Clearly, this adds up to an attractive return for our shareholders.

     Steve, that concludes my remarks.

GURGOVITS: Thanks Brian.

     Let me summarize a few key points. We believe this transaction creates strong value for shareholders by combining two complementary organizations. The transaction risk is low given our familiarity with Omega, its markets and our plan of integration. I would also like to point out that we’ve integrated four banks and several non-bank

9

acquisitions since 2004. In each and every case, cultures blended very well, cost takeouts were achieved and data systems were integrated successfully. We view this announcement as having several positive financial benefits and creating long-term value for both of our shareholders.

     That concludes our formal remarks for this call. I will now ask the operator to poll the audience for questions.
