I hope you will take advantage of the opportunity to direct the manner in which the shares of common stock allocated to your accounts under these plans will be voted at the Special Meeting. At the Special Meeting, shareholders will be asked to approve a Merger Agreement pursuant to which Alliance will be merged with and into WSFS Financial Corporation.

Enclosed with this letter is a voting instruction ballot, which will permit you to vote the shares allocated to your account(s) in the plans. After you have reviewed the Prospectus/Proxy Statement, we urge you to vote your shares held pursuant to the plans by marking, dating, signing and returning the enclosed voting instruction ballot(s) to the administrator of the plans, who will tabulate the votes for the Trustees of the plans. The Trustees will certify the totals for the purpose of having those shares voted at the Special Meeting. You may request a paper copy of the Prospectus/Proxy Statement by contacting Kathy Lynch at (610) 359-6907 or by email at klynch@alliancebk.com.

We urge each of you to vote, as a means of participating in the governance of the affairs of Alliance. If your voting instructions for the plans are not received, the shares allocated to your accounts will not be voted. Please note the enclosed material relates only to those shares which have been allocated to your accounts under these plans. You will receive other voting material for those shares owned by you individually and not under these plans.

In closing, I hope you will vote in the manner recommended by the board of directors, but even more importantly I encourage you to exercise your right to vote in whatever manner you deem appropriate.
