                              SUPERVISORY AGREEMENT

                                                           OTS Docket No.: 03346

     This Supervisory Agreement ("Agreement") is made as of February 13, 2006
(the "Effective Date"), by and between FIRST KEYSTONE BANK (the "Bank," OTS
Docket No. 03346), a federally chartered savings bank having its main office at
22 W. State Street, Media, Pennsylvania 19063-3311, and the OFFICE OF THRIFT
SUPERVISION ("OTS"), a federal bank regulatory agency within the United States
Department of the Treasury, acting through its Northeast Regional Director or
his designee ("Regional Director") and maintaining its Northeast Regional Office
at Harborside Financial Center Plaza Five, Suite 1600, Jersey City, New Jersey
07311.

     WHEREAS, OTS is the primary federal regulator of the Bank pursuant to the
Home Owners' Loan Act ("HOLA"), 12 U.S.C. Sections 1461 et seq., and is the
Bank's appropriate Federal banking agency for purposes of the Federal Deposit
Insurance Act ("FDI Act"), 12 U.S.C. Sections 1811 et seq.;(1) and

     WHEREAS, based on the findings set out in the Report of Examination
pertaining to OTS's regulatory examination of the Bank started on May 23, 2005
(the "2005 Report of Examination"), OTS is of the opinion that the Bank has
violated regulations and engaged in acts and practices that are considered to be
unsafe and unsound; and

     WHEREAS, OTS is of the opinion that grounds exist for the initiation of
administrative proceedings against the Bank; and

     WHEREAS, OTS is of the view that it is appropriate to take measures
intended to ensure that the Bank will comply with applicable laws and
regulations and engage in safe and sound practices; and

     WHEREAS, the Bank, acting through its Board of Directors (the "Board"),
without admitting or denying any unsafe and unsound practices or regulatory
violations, wishes to cooperate with OTS and to evidence its commitment to
operate prudently and to comply with all applicable laws and regulations.

----------
(1)  All references herein to the United States Code (U.S.C.) and the Code of
     Federal Regulations (C.F.R.) are as amended, unless otherwise indicated.

<PAGE>

     NOW THEREFORE, in consideration of the above premises and the mutual
undertakings set forth herein, the parties hereto agree as follows:

I. Compliance with Laws and Regulations. The Bank shall comply fully with the
following laws and regulations:

     (A)  12 C.F.R. Section 560.1(b) (concerning general lending standards);

     (B)  12 C.F.R. Section 560.101 (concerning real estate lending standards);

     (C) 12 C.F.R. Section 560.160 (concerning asset classification);

     (D) 12 C.F.R. Section 560.170 (concerning records for lending
transactions); and

     (E) 12 C.F.R. Sections 562.2 and 563.180 (concerning the filing of accurate
regulatory reports, including TFRs).

II. Commercial Lending.

     (A) Policies.

          Within ninety (90) calendar days after the Effective Date hereof, the
Board shall review and revise the Bank's Commercial Loan Policies so that they
address the critical elements set forth in Section 214 of OTS's Examination
Handbook and all weaknesses identified in the 2005 Report of Examination. The
revised Commercial Loan Policies must be acceptable to OTS and must require,
among other things:

          (1) That the Bank shall not directly or indirectly make, invest in,
purchase, refinance, extend, or otherwise materially modify, or commit to make,
invest in, purchase, refinance, extend, release collateral from, or otherwise
materially modify any commercial loan, unless:

               (a) It first obtains current, signed financial statements for the
borrower and each co-borrower, guarantor, and related entity; obtains current
Dun & Bradstreet reports, when available, for each borrower, co-borrower, and
guarantor to enable the Commercial Lending Department to determine how borrower
trade lines have performed, particularly when considering whether or not to make
an asset-based loan; uses reasonable efforts to confirm that all tax returns are
copies of returns that have been signed and actually filed; and confirms that
all questionable financial data has been documented;

               (b) It first prepares a documented analysis of the financial
statements/credit reports obtained;


                                       2

<PAGE>

               (c) It first documents the expected primary (and, if applicable,
each secondary) source of repayment;

               (d) If the contemplated loan is to an existing borrower, it first
prepares a narrative analysis of the borrower's overall credit relationship with
the Bank. Such analysis must include a schedule of each outstanding loan and a
discussion of the payment history concerning that loan;

               (e) It first documents whether or not the loan/overall lending
relationship complies with all approved lending policies;

               (f) If the contemplated loan/overall lending relationship does
not conform to approved lending policies, the transaction is approved by two
officers and/or directors other than an individual preparing a required analysis
or the Bank's Loan Committee;

               (g) If the loan is to be made to a financially weak borrower, or
a borrower with a less than satisfactory credit history, the credit terms
reflect the credit risk and the loan is appropriately rated; and

          (2) The reporting of commercial borrowers and guarantors to a
credit-reporting bureau.

Notwithstanding anything to the contrary in Section II(A), with respect to loans
in existence on the Effective Date, the Bank may provide a borrower with a
reasonable period of time from the due date of a commercial loan (not to exceed
90 days) to provide the required documentation; provided, further, if at the
time of renewal of an existing commercial loan the Bank improves the credit
quality of a loan through receipt of new guarantees or new collateral and fully
documents and supports the improved credit quality and collectability of the
loan, the Bank may extend or refinance a loan, provided that no additional funds
are disbursed.

Immediately following the Board's adoption of revised Commercial Loan Policies,
the Bank shall submit copies to OTS for its non-objection. If OTS provides
written notice that the revised Commercial Loan Policies are not acceptable, the
Bank shall promptly make such changes as are necessary to address OTS
objections.


                                       3

     (B) Department Performance Evaluation

The Board shall formally evaluate the performance of the Commercial Loan
Department no less frequently than semiannually, which shall include a review of
the performance of officers operating within the Commercial Loan Department. The
first such report shall be completed and submitted to the OTS by July 15, 2006
covering the six-month period ending June 30, 2006 and subsequent reports shall
be submitted no later than January 15 (covering each six-month period ending
December 31) and July 15 (covering each six-month period ending June 30). Such
reports shall be documented in the Board minutes and describe both the
evaluation process and the conclusions resulting therefrom.

III. Internal Loan Review Program.

     (A) For the quarter ending March 31, 2006, and not less frequently than
quarterly thereafter, the Bank must perform an internal loan review to determine
compliance with Board-approved lending policies, underwriting standards, and
loan administration requirements.

     (B) The Bank's Internal Audit Manager shall supervise the internal loan
reviews. The internal loan reviews may be conducted by a qualified service
provider or by qualified Bank staff, who must be independent of the Bank's
lending function.

     (C) The quarterly loan reviews must be based on: (i) a sample review of new
loans made during the previous quarter, (ii) all loans and lending relationships
exceeding $750,000, except for loans that are secured by single family,
owner-occupied real estate, and (iii) a sample of loans from the Bank's existing
loan portfolio.

     (D) As part of its Internal Loan Review Program, the Bank shall develop,
adopt, and implement a risk rating system for all high risk loans. Risk ratings
should reflect, among other things, quarterly classified assets shown on the
Bank's Thrift Financial Report ("TFR"), and must be updated at least quarterly
to reflect any change in risk.

     (E) On a quarterly basis, the Bank's Internal Audit Manager must provide
the Board with, and the Board must review and evaluate, a written report
documenting the findings and recommendations relating to the internal loan
reviews. The written report about the internal loan


                                       4

<PAGE>

reviews must conform to the standards set out in OTS's "Director's Guide to
Management Reports,"(2) and at a minimum, such report must provide information
about:

          (1) Each loan that represents an exception to applicable Bank loan
     policies and procedures (including each loan that was not properly
     approved) and the nature of the exception;

          (2) Each high risk loan for which the risk rating has changed since
     the last written report because of an increase in risk;

          (3) Each loan file lacking complete documentation (as required by the
     Bank's lending policies, underwriting standards, loan-servicing procedures,
     or other applicable guidance) and the nature of the exception; and

          (4) The current status of action taken to obtain missing or required
     loan documentation.

IV. Asset Classification.

     Within sixty (60) days after the Effective Date hereof, the Board shall
adopt, and the Bank shall implement, a revised formal written program to
identify and classify problem assets that satisfies the requirements of: (A) 12
C.F.R. Section 560.160; (B) section II.G. of the Part 570 Safety and Soundness
Standards; and (C) the Interagency Policy Statement on the Allowance for Loan
and Lease Losses Methodologies and Documentation for Banks and Savings
Institutions, dated July 2, 2001 (66 Fed. Reg. 35629, published on July 6,
2001).(3) Among other things, the program must:

     (A) be supervised by the Bank's Chief Financial Officer or another
designated management official who: (1) has no independent loan origination or
approval authority, (2) is independent of the appraisal preparation process, and
(3) reports directly to the Board or the Audit Committee thereof concerning the
program;

     (B) effectively identify risk in the various types of loans the Bank holds;

----------
(2)  The "Director's Guide" is currently available on the OTS' web site at
     http://www.ots.treas.gov/docs/4/48091.pdf.

(3)  The OTS distributed copies of the Interagency Policy Statement to savings
     institutions under cover of OTS CEO Memorandum 142, and a copy is currently
     available on the OTS' web site at
     http://www.ots.treas.gov/docs/2/25142.pdf.


                                       5

<PAGE>

     (C) ensure the proper identification of assets as "loss," "doubtful,"
"substandard," or "special mention" (collectively referred to as "Criticized
Assets") and the accurate reporting of each such asset to the Board at least
quarterly, to coincide with the preparation of the Bank's TFR. Loan
classifications shall be based on an assessment of all pertinent factors
affecting the likelihood that the loan will be repaid according to its terms,
including, without limitation, deficiencies uncovered in the Internal Loan
Review process required by Section IV above;

     (D) provide for the maintenance of an adequate allowance for loan and lease
losses ("ALLL") to reflect credit risk in the Bank's loan and lease portfolio;

     (E) ensure the prompt charge-off of loans, or portions of loans, that
available information indicates are uncollectible, or when applicable
regulations or guidance require that action;

     (F) require the timely and accurate reporting of Criticized Assets, ALLL,
and charge-offs in the Bank's TFRs.

V. Capital Level Requirements.

     The Bank shall not permit its Tier 1 (Core) Capital Ratio to fall below
7.50 percent, and it shall not permit its Total Risk-Based Capital ratio to fall
below 12.50 percent.

VI. Accuracy of Thrift Financial Reports.

     (A) No later than thirty (30) days after the Effective Date, the Bank shall
provide a written report to OTS identifying the steps the Bank has taken and
will take to: (1) ensure and confirm that all commercial loans are correctly
coded, properly identified, promptly and accurately entered in the Bank's loan
software system(s), and accurately reported in the Bank's TFRs; (2) ensure that
all criticized and adversely classified loans are properly identified and
accurately reported in the Bank's TFRs; (3) ensure the accuracy of the Bank's
TFRs in all respects; and (4) avoid a recurrence of the types of financial
reporting errors detailed in the 2005 Report of Examination.

     (B) Within one hundred twenty (120) days after the Effective Date, the
Internal Audit Manager shall (1) perform a complete review of the Bank's
information and data-gathering system used in preparing the Bank's TFRs, and (2)
shall provide a written report to the Board stating and discussing the results
of that review.

     (C) The Bank's internal audit scope shall include a review of the accuracy
of its TFR reporting.


                                       6

VII. Restriction on Asset Growth.

     Unless otherwise previously permitted in writing by OTS's Regional
Director, the Bank shall limit its asset growth in any quarter to an amount not
to exceed the greater of (i) net interest credited on deposit liabilities during
the quarter or (ii) three percent of total assets (annualized), consistent with
the October 28, 2005 submission by the Bank to the OTS. See OTS Regulatory
Bulletin 3b.

VIII. Board and Management Changes.

     The Bank is subject to the requirements and limitations set out in Subpart
H of Part 563 of OTS regulations (12 C.F.R. Sections 563.550 - .590). Without
limitation on such requirements and limitations, this means, among other things,
that, except as otherwise permitted by 12 C.F.R. Section 563.590, no person
shall be appointed to the position of or be hired as a member of the Board or as
a senior executive officer of the Bank unless -- (A) the Bank (or the
individual, if appropriate) has previously filed with the OTS an appropriate and
complete notice pursuant to 12 C.F.R. Part 563, Subpart H; and (B) the person's
commencement of service on behalf of the Bank is permissible under 12 C.F.R.
Section 563.585 and 12 U.S.C. Section 1831i.

IX. Compensation and Benefit Arrangements.

     The Bank shall not enter into, renew, extend, or revise any arrangement
related to compensation or benefits of any director or senior executive officer
of the Bank unless the Bank first -- (A) provides a minimum of 30 days' advance
written notice of the proposed transaction to OTS and (B) receives a written
notice of non-objection from OTS. This Section X is intended to implement the
OTS policies set out in OTS Regulatory Bulletin 27b and OTS Examination Handbook
Section 310 at page 310.7 ("Prior Approval of Employment Contracts").
Notwithstanding the foregoing, the Bank may amend any compensation or benefit
arrangement which is subject to the recently enacted Section 409A of the
Internal Revenue Code of 1986, as amended, by December 31, 2006 without the
prior approval of the OTS, provided such amendment is solely to achieve
compliance with Section 409A and will not result in an increase in the benefits
due the individual(s) subject to such compensation arrangement. A copy of any
such amendment adopted by the Bank will be provided to the OTS.


                                       7

X.   Severance and Indemnification Payments and Agreements to Make Such
     Payments.

     The restrictions in 12 C.F.R. Part 359 are applicable to the Bank. Such
restrictions concern the making of agreements (including employment agreements)
with severance provisions, "golden parachute payments," and "prohibited
indemnification payments." Without limitation on the generality of the
foregoing, this means, inter alia, that the Bank shall not make or agree to make
any "golden parachute payment," as that term is defined in 12 U.S.C. Section
1828(k) and 12 C.F.R. Part 359, except as may be permitted by the preceding
statutory and regulatory provisions.

XI.  Compliance With Agreement.

     (A) The Board and officers of the Bank shall take immediate action to cause
the Bank to comply with the terms of this Agreement and thereafter shall take
all actions necessary or appropriate to cause the Bank to continue to carry out
the provisions of this Agreement.

     (B) Within 15 days after the Effective Date, the Board shall appoint a
committee (the "Compliance Committee") comprised of 3 or more directors, the
majority of whom shall be outside directors, to monitor and coordinate the
Bank's compliance with the provisions of this Agreement. For purposes of this
subsection (B), "outside directors" shall mean members of the Board who are not
officers, employees, or principal stockholders of the Bank, its subsidiaries, or
its affiliates, and who do not have any material business dealings with the
Bank, its subsidiaries, or its affiliates.

     (C) Within 30 days after the end of each calendar quarter following the
date of this Agreement (March 31, June 30, September 30, and December 31), the
Compliance Committee shall submit a written progress report to the Board
detailing the actions taken to comply with each provision of this Agreement and
the results of those actions.

     (D) Within 15 days after its receipt from the Compliance Committee, the
Board shall forward a copy of the quarterly progress report described in this
subsection, with any additional comments made by the Board, to the Regional
Director and shall certify in writing that each director has reviewed the
report.

     Procedures.

</TABLE>

     (B) With respect to any plan, policy, or procedure that is timely filed and
prepared with reasonable diligence by the Bank, but nevertheless requires
modification to accommodate input by OTS occurring after the due date, no
violation will be found to exist for so long as the Bank (1) makes diligent and
good faith efforts to incorporate such modifications, and (2) complies with
subsequent OTS direction concerning the due dates for implementing such
modifications, provided, however, that OTS will consider whether events outside
the control of the Bank contributed to an inability to comply with a specific
commitment made in such plans, policies or procedures in determining whether a
violation exists.

     (C) During the term of this Agreement, any plans, policies, and procedures
that have been submitted to OTS for its approval or non-objection, and have been
approved or deemed to be not objectionable by OTS, shall not be amended or
rescinded without the prior written approval of the Regional Director.

violate any law, rule, regulation, or policy statement to which it is subject.

     (B) The paragraph headings herein are for convenience only and shall not
affect the construction hereof.

     (C) In case any provision in this Agreement is ruled to be invalid,
illegal, or unenforceable by the decision of any court of competent
jurisdiction, the validity, legality, and enforceability of the remaining
provisions hereof shall not in any way be affected or impaired thereby, unless
OTS determines otherwise in the exercise of its discretion.

XVII. Integration Clause; Relationship to Other Regulatory Actions.

     This Agreement represents, as of the Effective Date, the final written
agreement of the parties with respect to the subject matter hereof and
constitutes the sole agreement of the parties, as of the Effective Date.

their successors hereunder, any benefit or any legal or equitable right, remedy,
or claim under this Agreement.
