TO THE STOCKHOLDERS OF
     SHO-ME FINANCIAL CORP.:
 
    You are cordially invited to attend a special meeting of the stockholders
(the "Special Meeting") of Sho-Me Financial Corp. ("SFC") to be held at the
corporate office of SFC located at 109 N. Hickory Street, Mt. Vernon, Missouri
65712, at 11:00 a.m., local time, on October 8, 1997, notice of which is
enclosed.
 
    At the Special Meeting, you will be asked to consider and vote on a proposal
to adopt the Agreement and Plan of Reorganization (the "Agreement") by and
between SFC and Union Planters Corporation ("UPC") and a related Plan of Merger
(the "Plan of Merger") pursuant to which SFC will merge (the "Merger") with a
newly formed, wholly-owned subsidiary of UPC, with the effect that SFC will be
the surviving corporation resulting from the Merger. Upon consummation of the
Merger, each share of SFC common stock issued and outstanding (except for
certain shares held by SFC or UPC, or their respective subsidiaries, in each
case other than shares held in a fiduciary capacity or as a result of debts
previously contracted) will be converted into .7694 of a share of UPC common
stock (subject to possible adjustment as described in the accompanying Proxy
Statement/Prospectus), with cash being paid in lieu of issuing fractional
shares.
 
    Enclosed are the (i) Notice of Special Meeting, (ii) Proxy
Statement/Prospectus, (iii) proxy card for the Special Meeting and (iv)
pre-addressed return envelope for the proxy card. The Proxy Statement/Prospectus
describes in more detail the Agreement and the proposed Merger, including a
description of the conditions to consummation of the Merger and the effects of
the Merger on the rights of SFC stockholders. Please read these materials
carefully and consider thoughtfully the information set forth in them.
 
    Friedman, Billings, Ramsey & Co., Inc., an investment banking firm, has
issued its opinion to your Board of Directors regarding the fairness, from a
financial point of view, of the consideration to be paid by UPC pursuant to the
Agreement as of the date of the opinion. A copy of the opinion is attached as
Appendix C to the Proxy Statement/Prospectus.
 
    THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED AND ADOPTED THE AGREEMENT
AND THE PLAN OF MERGER AND CONSUMMATION OF THE MERGER CONTEMPLATED THEREBY, AND
UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR ADOPTION OF THE AGREEMENT AND THE PLAN
OF MERGER.
 
    Approval of the Agreement and the Plan of Merger will require the
affirmative vote of the holders of at least a majority of the issued and
outstanding shares of SFC common stock entitled to be voted at the Special
Meeting. Accordingly, whether or not you plan to attend the Special Meeting, you
are urged to complete, sign, and return promptly the enclosed proxy card. If you
attend the Special Meeting, you may vote in person even if you previously have
returned your proxy card. The proposed Merger with UPC is a significant step for
SFC and your vote on this matter is of great importance.
 
    ON BEHALF OF THE BOARD OF DIRECTORS, I URGE YOU TO VOTE FOR ADOPTION OF THE
AGREEMENT AND THE PLAN OF MERGER BY MARKING THE ENCLOSED PROXY CARD "FOR" ITEM
ONE.
 
    We look forward to seeing you at the Special Meeting.
 
                                          Sincerely,
 
                                          /s/ RAYMOND G. MERRYMAN

                                   PROSPECTUS
                         COMMON STOCK, $5.00 PAR VALUE
                           UNION PLANTERS CORPORATION
 
                                PROXY STATEMENT
 
                     FOR SPECIAL MEETING OF STOCKHOLDERS OF
                             SHO-ME FINANCIAL CORP.
 
     This Prospectus of Union Planters Corporation, a bank holding company
organized and existing under the laws of the State of Tennessee ("UPC"), relates
to up to 1,268,650 shares of common stock, $5.00 par value, of UPC (together
with associated "Preferred Share Rights" (as defined herein), "UPC Common
Stock"), including shares to be subject to assumed options and rights, which are
issuable to the stockholders of Sho-Me Financial Corp., a savings and loan
holding company organized and existing under the laws of the State of Delaware
("SFC"), upon consummation of the proposed merger (the "Merger") of SFC with UPC
Merger Subsidiary, Inc., a newly-formed, wholly-owned, first-tier subsidiary of
UPC ("UPC Merger Subsidiary"), with the effect that SFC will be the surviving
corporation of the Merger. The Merger will be consummated pursuant to the terms
of the Agreement and Plan of Reorganization, dated as of June 23, 1997 (the
"Agreement"), by and between UPC and SFC and the related Plan of Merger (the
"Plan of Merger"), by and between UPC Merger Subsidiary and SFC.
 
     At the effective time of the Merger (the "Effective Time"), except as
described herein, each issued and outstanding share of common stock, par value
$.01 per share, of SFC ("SFC Common Stock") will be converted into .7694 of a
share of UPC Common Stock, subject to certain possible adjustments described
herein (the "Exchange Ratio").
 
     The Exchange Ratio is adjustable upward only if certain conditions are met
concerning the quoted price of UPC Common Stock. The Board of Directors of SFC
would likely invoke the adjustment mechanism in the Agreement if the conditions
permit by giving notice of its election to terminate, in which case UPC must
determine whether to proceed with the Merger at a higher Exchange Ratio and
avoid termination. In making this determination, the principal factors UPC will
consider include the projected effect of the Merger on UPC's pro forma earnings
per share and whether UPC's assessment of SFC's earning potential as part of UPC
justifies the issuance of an increased number of shares of UPC Common Stock. If
UPC declines to adjust the Exchange Ratio, SFC may elect to proceed without the
adjustment by withdrawing its election to terminate, although it has no
intention to so elect without resoliciting stockholder approval. In making such
determination, the Board of Directors of SFC will consider whether the Merger
remains in the best interest of SFC and its stockholders, despite a decline in
the price of UPC Common Stock, and whether the consideration to be received by
the holders of SFC Common Stock remains fair from a financial point of view. See
"DESCRIPTION OF THE TRANSACTION -- Possible Adjustment of Exchange Ratio."
 
     This Prospectus also serves as the Proxy Statement of SFC, and is being
furnished to the stockholders of SFC in connection with the solicitation of
proxies by the Board of Directors of SFC for use at its special meeting of
stockholders (including any adjournment or postponement thereof, the "Special
Meeting"), to be held on October 8, 1997, to consider and vote upon the
Agreement and the Plan of Merger and the transactions contemplated therein. This
Proxy Statement/Prospectus ("Proxy Statement") and related materials enclosed
herewith are being mailed to stockholders of SFC on or about September 2, 1997.

                                    SUMMARY
 
     THE FOLLOWING IS A SUMMARY OF CERTAIN INFORMATION CONTAINED IN THIS PROXY
STATEMENT AND THE DOCUMENTS INCORPORATED HEREIN BY REFERENCE. THIS SUMMARY IS
NOT INTENDED TO BE A COMPLETE DESCRIPTION OF THE MATTERS COVERED IN THIS PROXY
STATEMENT AND IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED INFORMATION
APPEARING ELSEWHERE OR INCORPORATED BY REFERENCE IN THIS PROXY STATEMENT.
STOCKHOLDERS ARE URGED TO READ CAREFULLY THE ENTIRE PROXY STATEMENT, INCLUDING
THE APPENDICES. AS USED IN THIS PROXY STATEMENT, THE TERMS "UPC" AND "SFC" REFER
TO THOSE ENTITIES, RESPECTIVELY, AND, WHERE THE CONTEXT REQUIRES, TO THOSE
ENTITIES AND THEIR RESPECTIVE SUBSIDIARIES.
 
THE PARTIES
 
     SFC.  SFC, a Delaware corporation, is a savings and loan holding company
registered with the Office of Thrift Supervision ("OTS") under the Home Owners'
Loan Act, as amended ("HOLA"). Through its wholly-owned subsidiary, 1st Savings
Bank, f.s.b. ("1st Savings Bank"), a federally chartered savings bank, SFC
operates a network of retail banking offices serving four counties in Missouri
and offers a variety of financial services to meet the needs of the communities
it serves. As of June 30, 1997, SFC had total consolidated assets of
approximately $329 million, total consolidated deposits of approximately $200
million, and total consolidated stockholders' equity of approximately $30
million. The principal executive offices of SFC are located at 109 N. Hickory
Street, Mt. Vernon, Missouri 65712, and its telephone number at such address is
(417) 466-2171. Additional information with respect to SFC and its subsidiary is
included elsewhere herein and in documents incorporated by reference in this
Proxy Statement. See "AVAILABLE INFORMATION," "DOCUMENTS INCORPORATED BY
REFERENCE," and "BUSINESS OF SFC."
 
     UPC.  UPC, a Tennessee corporation, is a bank holding company registered
with the Board of Governors of the Federal Reserve System ("Federal Reserve")
under the Bank Holding Company Act of 1956, as amended (the "BHC Act") and a
savings and loan holding company registered with the OTS under the HOLA. As of
June 30, 1997, UPC had total consolidated assets of approximately $14.8 billion,
total consolidated loans of approximately $10.4 billion, total consolidated
deposits of approximately $11.2 billion, and total consolidated stockholders'
equity of approximately $1.4 billion.
 
     UPC conducts its business activities through its principal bank subsidiary,
the $5.5 billion asset Union Planters National Bank, founded in 1869 and
headquartered in Memphis, Tennessee, and 32 other bank subsidiaries and one
savings bank subsidiary located in Tennessee, Mississippi, Missouri, Arkansas,
Louisiana, Alabama, and Kentucky (collectively, the "UPC Banking Subsidiaries").
Through the UPC Banking Subsidiaries, UPC provides a diversified range of
financial services in the communities in which it operates, including consumer,
commercial and corporate lending, retail banking and other financial services
traditionally furnished by full-service financial institutions. UPC also is
engaged in: mortgage origination and servicing; investment management and trust
services; the issuance and servicing of credit and debit cards; and the
origination, packaging, and securitization of loans, primarily the
government-guaranteed portions of Small Business Administration loans; the
purchase of delinquent Federal Housing Administration and Department of Veterans
Affairs ("FHA/VA") government-insured/guaranteed loans from third parties and
from Government National Mortgage Association ("GNMA") pools serviced for
others; full service and discount brokerage; and the sale of annuities and
bank-eligible insurance products.
 
     Through the UPC Banking Subsidiaries, UPC operates approximately 432
banking offices and 564 automated teller machines ("ATMs"). UPC's total assets
at June 30, 1997 are allocable by state (before consolidating adjustments)
approximately as follows: $9.7 billion in Tennessee; $2.3 billion in
Mississippi; $1.2 billion in Missouri; $800 million in Arkansas; $609 million in
Louisiana; $440 million in Alabama; and $113 million in Kentucky.
 
     Acquisitions have been, and are expected to continue to be, an important
part of the expansion of UPC's business. UPC completed 12 acquisitions in 1993,
13 in 1994, three in 1995 and seven in 1996, adding approximately $1.7 billion
in total assets in 1993, $3.8 billion in 1994, $1.3 billion in 1995 and $4.2
billion in 1996. Thus far in 1997, UPC has entered into definitive agreements to
acquire six financial institutions in addition to SFC which had aggregate total
assets of approximately $3.7 billion at June 30, 1997 (of which four
 
                                        1
<PAGE>   10
 
of such acquisitions are deemed probable for financial reporting purposes and
are collectively referred to as the "Other Pending Acquisitions" and the
remaining two of such acquisitions are not deemed probable for financial
reporting purposes and are collectively referred to as the "Other Announced
Acquisitions"). For additional information, see "BUSINESS OF UPC  --  Recent
Developments." For a discussion of UPC's acquisition program and UPC
management's philosophy on that subject, see the caption "Acquisitions" (on page
6) and Note 2 to UPC's audited consolidated financial statements for the years
ended December 31, 1996, 1995, and 1994 (on pages 45 and 46) contained in UPC's
Annual Report to Shareholders, which is Exhibit 13 to UPC's Annual Report on
Form 10-K for the year ended December 31, 1996, which Exhibit 13 is incorporated
by reference herein to the extent indicated herein.
 
     UPC expects to continue to take advantage of the consolidation of the
financial services industry by further developing its franchise through the
acquisition of financial institutions. Future acquisitions may entail the
payment by UPC of consideration in excess of the book value of the underlying
net assets acquired, may result in the issuance of additional shares of UPC
capital stock or the incurring of additional indebtedness by UPC, and could have
a dilutive effect on the earnings or book value per share of UPC Common Stock.
Moreover, significant charges against earnings are sometimes required incidental
to acquisitions. For a description of acquisitions which are currently pending,
see "BUSINESS OF UPC -- Recent Developments."
 
     The principal executive offices of UPC are located at 7130 Goodlett Farms
Parkway, Memphis, Tennessee 38018, and its telephone number at such address is
(901) 580-6000. Additional information with respect to UPC and its subsidiaries
is included elsewhere herein and in documents incorporated by reference in this
Proxy Statement. See "AVAILABLE INFORMATION," "DOCUMENTS INCORPORATED BY
REFERENCE" and "BUSINESS OF UPC."
 
MEETING OF STOCKHOLDERS
 
     This Proxy Statement is being furnished to the holders of SFC Common Stock
in connection with the solicitation by the SFC Board of Directors of proxies for
use at the Special Meeting at which SFC stockholders will be asked to vote upon
(i) a proposal to adopt the Agreement and the Plan of Merger and (ii) such other
business as may properly come before the meeting. The Special Meeting will be
held at the corporate office of SFC located at 109 N. Hickory Street, Mt.
Vernon, Missouri, at 11:00 a.m. local time, on October 8, 1997. See "SPECIAL
MEETING OF SFC STOCKHOLDERS -- Date, Place, Time, and Purpose."
 
     SFC's Board of Directors has fixed the close of business on August 25,
1997, as the record date (the "SFC Record Date") for determination of the
stockholders entitled to notice of and to vote at the Special Meeting. Only
holders of record of shares of SFC Common Stock on the SFC Record Date will be
entitled to notice of and to vote at the Special Meeting. Each share of SFC
Common Stock is entitled to one vote. Stockholders who execute proxies retain
the right to revoke them at any time prior to the proxies being voted at the
Special Meeting. On the SFC Record Date, there were 1,498,636 shares of SFC
Common Stock issued and outstanding. See "SPECIAL MEETING OF SFC
STOCKHOLDERS -- Record Date, Voting Rights, Required Vote and Revocability of
Proxies."
 
     Adoption of the Agreement and the Plan of Merger and the transactions
contemplated thereby requires the affirmative vote of the holders of at least a
majority of the issued and outstanding shares of SFC Common Stock entitled to be
voted at the Special Meeting. Directors and executive officers of SFC and their
affiliates are entitled to vote 10.34% of the outstanding shares of SFC Common
Stock. See "SPECIAL MEETING OF SFC STOCKHOLDERS -- Record Date, Voting Rights,
Required Vote and Revocability of Proxies."
 
THE MERGER
 
     GENERAL.  The Agreement provides for the acquisition of SFC by UPC pursuant
to the merger of SFC with UPC Merger Subsidiary, a newly-formed, wholly-owned,
first-tier subsidiary of UPC with the effect that SFC will be the surviving
corporation resulting from the Merger. At the Effective Time, each share of SFC
Common Stock then issued and outstanding (excluding shares held by SFC, UPC, or
their respective subsidiaries, in each case other than shares held in a
fiduciary capacity or as a result of debts previously
 
                                        2
<PAGE>   11
 
contracted) will be converted into .7694 of a share of UPC Common Stock, subject
to possible adjustment as described below (the "Exchange Ratio").
 
     In the event both of the following conditions are satisfied, (i) the
"Average Closing Price" (defined in the Agreement as the average of the daily
last sale prices of UPC Common Stock quoted on the NYSE-Composite Transactions
List (as reported by The Wall Street Journal or, if not reported thereby,
another authoritative source as selected by UPC) for the 20 consecutive full
trading days on which such shares are traded on the NYSE ending at the close of
trading on the later of the date of the Special Meeting and the date on which
the last required consent of any regulatory authority required for the Merger
shall be received (the "Determination Date")) is less than $41.50 and (ii) (1)
the quotient obtained by dividing the Average Closing Price by $51.875 (the "UPC
Ratio") is less than (2) the quotient obtained by dividing the weighted average
of the closing prices (the "Index Price") of 17 bank holding companies
designated in the Agreement (the "Index Group") on the Determination Date by the
Index Price on June 30, 1997 less 15% (the "Index Ratio"), then SFC will have
the right to terminate the Agreement unless UPC elects to adjust the Exchange
Ratio in the manner described under "DESCRIPTION OF TRANSACTION -- Possible
Adjustment of Exchange Ratio." Under no circumstances would the Exchange Ratio
be less than .7694 of a share of UPC Common Stock for each share of SFC Common
Stock. The possible upward adjustment of the Exchange Ratio depends on the
factors mentioned above and is not subject to a contractual limit. See
"DESCRIPTION OF TRANSACTION -- Possible Adjustment of Exchange Ratio."
 
     No fractional shares of UPC Common Stock will be issued. Rather, cash
(without interest) will be paid in lieu of any fractional share interest to
which any SFC stockholder would be entitled upon consummation of the Merger, in
an amount equal to such fractional part of a share of UPC Common Stock
multiplied by the market value of one share of UPC Common Stock at the Effective
Time. The market value of one share of UPC Common Stock at the Effective Time
shall be the closing price of such common stock on the NYSE-Composite
Transactions List (as reported by The Wall Street Journal or, if not reported
thereby, another authoritative source as selected by UPC) on the last trading
day preceding the Effective Time. See "DESCRIPTION OF TRANSACTION -- General."
 
     At the Effective Time, each award, option, or other right to purchase or
acquire shares of SFC Common Stock ("SFC Options") granted by SFC under the SFC
Stock Plans, as that term is defined in the Agreement, which is outstanding at
the Effective Time, whether or not exercisable, will be converted into and
become rights with respect to UPC Common Stock on a basis adjusted to reflect
the Exchange Ratio. See "DESCRIPTION OF TRANSACTION -- Effect of the Merger on
SFC Options."
 
     As of the SFC Record Date, SFC had 1,498,636 shares of SFC Common Stock
issued and outstanding and 149,946 additional shares of SFC Common Stock subject
to SFC Options. Based upon an Exchange Ratio of .7694, upon consummation of the
Merger, UPC would issue approximately 1,153,051 shares of UPC Common Stock,
excluding shares subject to assumed SFC Options. Accordingly, UPC would then
have issued and outstanding approximately 68,081,532 shares of UPC Common Stock
based on the number of shares of UPC Common Stock issued and outstanding on July
31, 1997 (and excluding shares to be issued pursuant to Other Pending
Acquisitions and shares to be issued pursuant to the exercise of stock options
and for other purposes).
 
     REASONS FOR THE MERGER, RECOMMENDATIONS OF THE BOARD OF DIRECTORS OF
SFC.  The Board of Directors of SFC believes that the Agreement, the Plan of
Merger, and the Merger are in the best interests of SFC and its stockholders.
THE SFC DIRECTORS UNANIMOUSLY RECOMMEND THAT SFC STOCKHOLDERS VOTE FOR ADOPTION
OF THE AGREEMENT AND THE PLAN OF MERGER. The Board of Directors of SFC believes
that the Merger will result in a company with expanded opportunities for
profitable growth and that the combined resources and capital of SFC and UPC
will provide an enhanced ability to compete in the changing and competitive
financial services industry. See "DESCRIPTION OF TRANSACTION -- Background of
and Reasons for the Merger."
 
     In unanimously approving the Agreement and the Plan of Merger, SFC's
directors considered, among other things, SFC's and UPC's financial condition,
the financial terms and income tax consequences of the Merger, the likelihood of
the Merger being approved by regulatory authorities without undue conditions or
delay, legal advice concerning the proposed Merger, the views of Friedman,
Billings, Ramsey & Co., Inc.
 
                                        3
<PAGE>   12
 
("FBR") as to the fairness of the Exchange Ratio, from a financial point of
view, to the stockholders of SFC, and the fairness of the terms of the Merger to
SFC stockholders. See "DESCRIPTION OF TRANSACTION -- Background of and Reasons
for the Merger."
 
     OPINION OF FINANCIAL ADVISOR.  FBR has rendered an opinion to the Board of
Directors of SFC that, based on and subject to the procedures, matters, and
limitations described in its opinion and such other matters as it considered
relevant, as of the date of its opinion, the Exchange Ratio is fair, from a
financial point of view, to the stockholders of SFC. The opinion of FBR dated as
of the date of this Proxy Statement is attached as Appendix C to this Proxy
Statement. SFC stockholders are urged to read the opinion in its entirety for a
description of the procedures followed, matters considered, and limitations on
the reviews undertaken in connection therewith. See "DESCRIPTION OF
TRANSACTION -- Opinion of SFC's Financial Advisor."
 
     EFFECTIVE TIME.  Subject to the conditions to the obligations of the
parties to effect the Merger, the Effective Time will occur on the date and at
the time that the Certificate of Merger becomes effective with the Delaware
Secretary of State. Unless otherwise agreed upon by SFC and UPC, and subject to
the conditions to the obligations of the parties to effect the Merger, the
parties will use their reasonable efforts to cause the Effective Time to occur
on such date as may be designated by UPC within 30 days following the last to
occur of (i) the effective date (including the expiration of any applicable
waiting period) of the last consent of any regulatory authority required for the
Merger, (ii) the date on which the stockholders of SFC adopt the Agreement and
the Plan of Merger as required by applicable law, and (iii) the date on which
all other conditions precedent to each party's obligations under the Agreement
have been satisfied or waived (to the extent waivable). See "DESCRIPTION OF
TRANSACTION -- Effective Time of the Merger," "--  Conditions to Consummation of
the Merger," and "--  Waiver, Amendment, and Termination."
 
     NO ASSURANCE CAN BE PROVIDED THAT THE NECESSARY STOCKHOLDER AND REGULATORY
APPROVALS CAN BE OBTAINED OR THAT THE OTHER CONDITIONS PRECEDENT TO THE MERGER
CAN OR WILL BE SATISFIED. SFC AND UPC ANTICIPATE THAT ALL CONDITIONS TO THE
CONSUMMATION OF THE MERGER WILL BE SATISFIED SO THAT THE MERGER CAN BE
CONSUMMATED DURING THE FIRST QUARTER OF 1998. HOWEVER, DELAYS IN THE
CONSUMMATION OF THE MERGER COULD OCCUR.
 
     EXCHANGE OF STOCK CERTIFICATES.  Promptly after the Effective Time, UPC
will cause Union Planters National Bank, Memphis, Tennessee, acting in its
capacity as exchange agent for UPC (the "Exchange Agent"), to mail to each
holder of record of a certificate or certificates (collectively, the
"Certificates") which, immediately prior to the Effective Time, represented
outstanding shares of SFC Common Stock, a letter of transmittal and instructions
for use in effecting the surrender and cancellation of the Certificates in
exchange for certificates representing shares of UPC Common Stock. Cash will be
paid to the holders of SFC Common Stock in lieu of the issuance of any
fractional shares of UPC Common Stock. In no event will the holder of any
surrendered Certificate(s) be entitled to receive interest on any cash to be
issued to such holder, and in no event will SFC, UPC, or the Exchange Agent be
liable to any holder of SFC Common Stock for any UPC Common Stock or dividends
thereon or cash delivered in good faith to a public official pursuant to any
applicable abandoned property, escheat, or similar law.
 
     REGULATORY APPROVAL AND OTHER CONDITIONS.  The Merger is subject to the
prior approval of the Federal Reserve. An application has been filed with this
regulatory authority for the requisite approval. THERE CAN BE NO ASSURANCE THAT
SUCH REGULATORY APPROVAL WILL BE OBTAINED OR AS TO THE TIMING OF ANY SUCH
APPROVAL.
 
     Consummation of the Merger is subject to various other conditions,
including receipt of the required approval of SFC stockholders, receipt of an
opinion of counsel as to the tax-free nature of certain aspects of the Merger,
and certain other conditions. See "DESCRIPTION OF TRANSACTION -- Regulatory
Approval" and "--  Conditions to Consummation of the Merger."
 
     WAIVER, AMENDMENT, AND TERMINATION.  The Agreement may be terminated and
the Merger abandoned at any time prior to the Effective Time by mutual consent
of the Boards of Directors of SFC and UPC, or by the action of the Board of
Directors of either company under certain circumstances, including, but not
limited to, if (i) the Merger is not consummated by June 30, 1998, unless the
failure to consummate by such date is due to a willful breach of the Agreement
by the party seeking to terminate or (ii) IN CERTAIN CIRCUMSTANCES, AN
 
                                        4
<PAGE>   13
 
ADJUSTMENT IS NOT MADE TO THE EXCHANGE RATIO. To the extent permitted by law,
the Agreement may be amended upon the written agreement of UPC and SFC without
the approval of stockholders, whether before or after adoption of the Agreement
and the Plan of Merger by SFC stockholders; provided, that after such adoption,
there shall be made no amendment that modifies in any material respect the
consideration to be received by SFC stockholders, without the approval of such
stockholders. See "DESCRIPTION OF TRANSACTION -- Possible Adjustment of Exchange
Ratio" and "--  Waiver, Amendment, and Termination."
 
     DISSENTERS' RIGHTS.  Pursuant to DGCL Section 262, the holders of SFC
Common Stock do not have dissenters' rights with respect to the Merger. See
"DESCRIPTION OF TRANSACTION -- Dissenters' Rights."
 
     INTERESTS OF CERTAIN PERSONS IN THE MERGER.  Certain members of SFC's
management and Board of Directors have interests in the Merger in addition to
their interests as stockholders of SFC generally. These interests relate to: (i)
the election of one member of the SFC Board of Directors and management, David
J. Tooley, to the Board of Directors of the UPC subsidiary operating in
Springfield, Missouri; (ii) the formation and maintenance of a Mt. Vernon,
Missouri Advisory Board until July 31, 2001; (iii) the assumption by UPC of all
employment, severance, consulting and other compensation contracts disclosed to
UPC between any SFC company and any current or former director, officer or
employee thereof, including all obligations under the Change in Control
Severance Agreements between SFC and Raymond G. Merryman, President and Chief
Executive Officer, David J. Tooley, Executive Vice President, and Greg Steffens,
Chief Financial Officer, including their rights to receive change in control
payments thereunder of approximately $214,973, $217,833 and $130,117,
respectively; (iv) the right to receive individual payments of $50,000 for each
of Messrs. Merryman and Tooley in consideration of their agreement to enter into
written agreements not to compete with UPC for a period of two years following
the Effective Time; (v) UPC permitting SFC to take certain steps and make
certain payments, to the extent permitted by law, for the purpose of maximizing
allocations under the SFC Employee Stock Ownership Plan ("ESOP") to SFC
employees; (vi) the eligibility of former employees of SFC who become employees
of UPC for certain employee benefits; (vii) the transfer of certain club
memberships from corporate to personal status; and (viii) the continued
indemnification by UPC of the former directors, officers, employees and agents
of SFC and its subsidiaries following consummation of the Merger. See
"DESCRIPTION OF TRANSACTION -- Interests of Certain Persons in the Merger."
 
     CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER.  It is intended that
the Merger will be treated as a reorganization within the meaning of Section 368
of the Internal Revenue Code of 1986, as amended (the "Code"). Accordingly, no
gain or loss will be recognized by a SFC stockholder upon the exchange of such
stockholder's shares of SFC Common Stock solely for shares of UPC Common Stock
(including any associated UPC Rights). Subject to the provisions and limitations
of Section 302(a) of the Code, gain or loss will be recognized with respect to
cash received in lieu of fractional shares. Gain recognition, if any, will not
be in excess of the amount of cash received. Consummation of the Merger is
conditioned upon receipt by SFC and UPC of an opinion of Alston & Bird LLP
substantially to this effect. TAX CONSEQUENCES OF THE MERGER FOR INDIVIDUAL
TAXPAYERS CAN VARY, HOWEVER, AND ALL SFC STOCKHOLDERS ARE URGED TO CONSULT THEIR
OWN TAX ADVISORS TO DETERMINE THE EFFECT OF THE MERGER ON THEM UNDER FEDERAL,
STATE, LOCAL AND FOREIGN TAX LAWS. For a further discussion of the federal
income tax consequences of the Merger, see "DESCRIPTION OF TRANSACTION --
Certain Federal Income Tax Consequences."
 
     ACCOUNTING TREATMENT.  It is intended that the Merger will be accounted for
as a purchase transaction for accounting and financial reporting purposes. See
"DESCRIPTION OF TRANSACTION -- Accounting Treatment."
 
     CERTAIN DIFFERENCES IN STOCKHOLDERS' RIGHTS.  At the Effective Time, SFC
stockholders, whose rights are governed by SFC's Certificate of Incorporation,
as amended, and Bylaws and by the DGCL, will automatically become UPC
stockholders, and their rights as UPC stockholders will be governed by UPC's
Restated Charter and Bylaws and the Tennessee Business Corporation Act (the
"TBCA"). The rights of UPC stockholders differ from the rights of SFC
stockholders in certain important respects, including with respect to certain
anti-takeover provisions provided for in UPC's Restated Charter and Bylaws. See
"EFFECT OF THE MERGER ON RIGHTS OF STOCKHOLDERS."
 
                                        5
<PAGE>   14
 
     OPTION AGREEMENT.  SFC, as issuer, and UPC, as grantee, entered into a
stock option agreement (the "Option Agreement") pursuant to which SFC granted
UPC an option to purchase, under certain circumstances and subject to certain
possible adjustments and limitations, up to 298,228 shares of SFC Common Stock
at a price of $37.00 per share. Notwithstanding anything to the contrary
contained in the Option Agreement, in no event may the Total Profit or the
Notional Total Profit (each as defined in the Option Agreement) of UPC exceed
$3.0 million. The Option Agreement is exercisable upon the occurrence of certain
events that create the potential for another party to acquire control of SFC. To
the knowledge of SFC, no such event which would permit exercise of the Option
Agreement has occurred as of the date of this Proxy Statement. The Option
Agreement was granted by SFC as a condition of and in consideration for UPC's
entering into the Agreement and is intended to increase the likelihood that the
Merger will be effected by making it more difficult and more expensive for a
third party to acquire control of SFC. See "DESCRIPTION OF TRANSACTION -- Option
Agreement."
 
     CONDUCT OF BUSINESS PENDING THE MERGER.  Each party has agreed in the
Agreement to, among other things, operate its business and to take no action
that would materially adversely affect the ability of any party to perform its
covenants and agreements under the Agreement. In addition, SFC has agreed not to
take certain actions relating to the operation of SFC pending consummation of
the Merger without the prior written consent of UPC, except as otherwise
permitted by the Agreement, including, among other things: (i) becoming
responsible for any obligation for borrowed money in excess of an aggregate of
$250,000, except in the ordinary course of business consistent with past
practices; (ii) paying any dividends, or, subject to certain exceptions,
exchanging any shares of its capital stock, issuing any additional shares of its
capital stock or giving any person the right to acquire any such shares; (iii)
acquiring control over any other entity; (iv) subject to certain exceptions,
granting any increase in compensation or benefits, or paying any bonus, to any
of its directors, officers, or employees; or (v) except as previously disclosed
to UPC, modifying or adopting any employee benefit plans, including any
employment contract. See "DESCRIPTION OF TRANSACTION -- Conduct of Business
Pending the Merger."

    represents the closing sale price of a share of UPC Common Stock on such
    date multiplied by an Exchange Ratio of .7694. See "COMPARATIVE MARKET

EQUIVALENT AND PRO FORMA PER SHARE DATA
 
     The following table sets forth certain comparative per share data relating
to earnings before extraordinary items and accounting changes, cash dividends,
and book value on (i) a historical basis for UPC and SFC; (ii) a pro forma
combined basis per share of UPC Common Stock, giving effect to the Merger and
the "Other Pending Acquisitions" (as defined under "BUSINESS OF UPC -- Recent
Developments"); and (iii) an

equivalent pro forma basis per share of SFC Common Stock, giving effect to the
Merger and the Other Pending Acquisitions. Pro forma data is not presented
separately for SFC because it would not be significantly different from UPC's
results. The UPC pro forma combined information and the SFC equivalent pro forma
information give effect to the Merger and the Other Pending Acquisitions and
reflect an Exchange Ratio of .7694. The Merger is expected to be accounted for
using the purchase method of accounting and the Other Pending Acquisitions are
expected to be accounted for using the pooling-of-interests method of
accounting. The pro forma information for 1996 and the six months ended June 30,
1997 reflect the acquisition of SFC and the Other Pending Acquisitions as of
January 1, 1996. The pro forma information for 1995 and 1994 reflect only the
assumed acquisition of Magna Bancorp, Inc. because the Merger and the Other
Pending Acquisitions (excluding Magna Bancorp, Inc.) are not considered
significant to UPC from a financial statement presentation standpoint. The pro
forma data are presented for information purposes only and are not necessarily
indicative of the results of operations or combined financial position that
would have resulted had the Merger or the Other Acquisitions (as defined under
"BUSINESS OF UPC -- Recent Developments") been consummated at the dates or
during the periods indicated, nor are they necessarily indicative of future
results of operations or combined financial position.
 
     The information shown below should be read in conjunction with, and is
qualified in its entirety by, the historical consolidated financial statements
of UPC and SFC, including the respective notes thereto. See "DOCUMENTS
INCORPORATED BY REFERENCE," "-- Selected Financial Data," and "BUSINESS OF

(1) Reference is made to "Basis of Presentation" in Note 1 to UPC's audited
    consolidated financial statements contained in the 1996 Annual Report to
    Shareholders, which is incorporated by reference. See "DOCUMENTS
    INCORPORATED BY REFERENCE."
 
(2) Share and per share amounts have been retroactively restated for significant
    acquisitions accounted for as pooling of interests.
 
(3) Long-term debt includes Medium-Term Bank Notes, Federal Home Loan Bank
    ("FHLB") advances, subordinated notes and debentures, obligations under
    capital leases, mortgage indebtedness, Trust Preferred Securities, and notes
    payable with maturities greater than one year.
 
(4) Average balances and calculations do not include the impact of the net
    unrealized gain or loss on available for sale securities.
 
(5) Leader Financial Corporation ("Leader") was organized as a holding company
    on March 18, 1993 in connection with the conversion of its principal
    subsidiary, Leader Federal Bank for Savings, from a federal mutual savings
    bank to a federally-chartered capital stock savings bank. (See Note 2 to
    UPC's consolidated financial statements contained in the 1996 Annual Report
    to Shareholders). Accordingly, earnings per share for the year ended
    December 31, 1992 is calculated using only UPC's historical net earnings and
    the calculation of earnings per share for the year ended December 31, 1993
    is based on UPC's historical net earnings for 1993 plus Leader's fourth
    quarter net earnings, since the stock conversion occurred on September 30,
    1993.
 
(6) FHA/VA government-insured/guaranteed loans have been excluded, since they
    represent minimal credit risk to UPC.

                      SPECIAL MEETING OF SFC STOCKHOLDERS
 
DATE, PLACE, TIME, AND PURPOSE
 
     This Proxy Statement is being furnished to the holders of SFC Common Stock
in connection with the solicitation by the SFC Board of Directors of proxies for
use at the Special Meeting, and at any and all adjournments or postponements
thereof, at which SFC stockholders will be asked to vote upon a proposal to
approve the adoption of the Agreement and the Plan of Merger. The Special
Meeting will be held at the corporate offices of SFC at 109 N. Hickory Street,
Mt. Vernon, Missouri 65712, at 11:00 a.m., local time, on October 8, 1997. See
"DESCRIPTION OF TRANSACTION."
 
RECORD DATE, VOTING RIGHTS, REQUIRED VOTE AND REVOCABILITY OF PROXIES
 
     The close of business on August 25, 1997, has been fixed as the SFC Record
Date for determining holders of outstanding shares of SFC Common Stock entitled
to notice of and to vote at the Special Meeting. Only holders of SFC Common
Stock of record on the books of SFC at the close of business on the SFC Record
Date are entitled to notice of and to vote at the Special Meeting. As of the SFC
Record Date, there were 1,498,636 shares of SFC Common Stock issued and
outstanding held by 543 holders of record.
 
     Holders of SFC Common Stock are entitled to one vote on each matter
considered and voted upon at the Special Meeting for each share of SFC Common
Stock held of record as of the SFC Record Date. To hold a vote on any proposal,
a quorum must be assembled, which requires that at least one-third of the shares
of SFC Common Stock issued and outstanding and entitled to vote be present in
person or represented by proxy. In determining whether a quorum exists at the
Special Meeting for purposes of all matters to be voted on, all votes "for" or
"against," as well as all abstentions, with respect to the proposal receiving
the most such votes, will be counted. Adoption of the Agreement and the Plan of
Merger requires an affirmative vote of the holders of at least a majority of the
issued and outstanding shares of SFC Common Stock entitled to be voted at the
Special Meeting. Consequently, with respect to the proposal to adopt the
Agreement and the Plan of Merger, abstentions and broker non-votes will be
counted as part of the base number of votes to be used in determining if the
proposal has received the requisite number of votes for adoption. Thus, an
abstention or a broker non-vote will have the same effect as a vote "against"
such proposal.
 
     Shares of SFC Common Stock represented by properly executed proxies, if
such proxies are received in time for exercise and not revoked, will be voted in
accordance with the instructions indicated on the proxies. IF NO INSTRUCTIONS
ARE INDICATED, SUCH PROXIES WILL BE VOTED FOR THE PROPOSAL TO ADOPT THE
AGREEMENT AND THE PLAN OF MERGER AND, IN THE DISCRETION OF THE PROXY HOLDER, AS
TO ANY OTHER MATTER WHICH MAY COME PROPERLY BEFORE THE SPECIAL MEETING. IF
NECESSARY, THE PROXY HOLDER MAY VOTE IN FAVOR OF A PROPOSAL TO ADJOURN THE
SPECIAL MEETING IN ORDER TO PERMIT FURTHER SOLICITATION OF PROXIES IN THE EVENT
THERE ARE NOT SUFFICIENT VOTES TO APPROVE THE FOREGOING PROPOSAL AT THE TIME OF
THE SPECIAL MEETING. HOWEVER, NO PROXY HOLDER WILL VOTE ANY PROXIES VOTED
"AGAINST" ADOPTION OF THE AGREEMENT AND THE PLAN OF MERGER "FOR" A PROPOSAL TO
ADJOURN THE SPECIAL MEETING.
 
     FAILURE BOTH TO RETURN THE PROXY CARD AND TO VOTE IN PERSON AT THE SPECIAL
MEETING WILL HAVE THE EFFECT OF A VOTE CAST AGAINST THE PROPOSAL TO ADOPT THE
AGREEMENT AND THE PLAN OF MERGER.
 
     A SFC stockholder who has given a proxy may revoke it at any time prior to
its exercise at the Special Meeting by (i) giving written notice of revocation
to the Secretary of SFC, (ii) properly submitting to SFC a duly executed proxy
bearing a later date, or (iii) attending the Special Meeting and voting in
person. All written notices of revocation and other communications with respect
to revocation of proxies should be addressed as follows: Sho-Me Financial Corp.,
109 N. Hickory Street, Mt. Vernon, Missouri 65712; Attention: Barbara Rubison,
Corporate Secretary.
 
     The directors and executive officers of SFC and their affiliates
beneficially owned, as of the SFC Record Date, 155,019 shares (excluding shares
underlying SFC Options), or approximately 10.34% of the then issued and
outstanding shares of SFC Common Stock.

SOLICITATION OF PROXIES
 
     Proxies may be solicited by the directors, officers, and employees of SFC
by mail, in person, or by telephone or telegraph. Such persons will receive no
additional compensation for such services. SFC may make arrangements with
brokerage firms and other custodians, nominees, and fiduciaries, if any, for the
forwarding of solicitation materials to the beneficial owners of SFC Common
Stock held of record by such persons. Any such brokers, custodians, nominees,
and fiduciaries will be reimbursed for the reasonable out-of-pocket expenses
incurred by them for such services. All expenses associated with the
solicitation of proxies, other expenses associated with the Special Meeting, and
expenses related to the printing and mailing of this Proxy Statement, will be
shared by UPC and SFC as provided in the Agreement. SFC presently intends to use
the services of a proxy soliciting firm in connection with the solicitation of
proxies for the Special Meeting. See "DESCRIPTION OF TRANSACTION -- Expenses and
Fees."
 
RECOMMENDATION
 
     THE BOARD OF DIRECTORS OF SFC HAS UNANIMOUSLY APPROVED THE AGREEMENT, THE
PLAN OF MERGER, AND THE MERGER CONTEMPLATED THEREBY, BELIEVES THAT THE PROPOSAL
TO ADOPT THE AGREEMENT AND THE PLAN OF MERGER IS IN THE BEST INTERESTS OF SFC
AND ITS STOCKHOLDERS, AND UNANIMOUSLY RECOMMENDS THAT THE SFC STOCKHOLDERS VOTE
FOR APPROVAL OF THE PROPOSAL TO ADOPT THE AGREEMENT AND THE PLAN OF MERGER.

                           DESCRIPTION OF TRANSACTION
 
     The following information describes material aspects of the Merger. This
description does not purport to be complete and is qualified in its entirety by
reference to the Appendices hereto, including the Agreement and the Plan of
Merger, which are attached as Appendices A and B, respectively, to this Proxy
Statement and incorporated herein by reference. All stockholders are urge to
read the Appendices in their entirety.
 
GENERAL
 
     The Agreement provides for the acquisition of SFC by UPC pursuant to the
merger of SFC with UPC Merger Subsidiary, a newly-formed, a wholly-owned,
first-tier subsidiary of UPC, with the effect that SFC will be the surviving
corporation resulting from the Merger. At the Effective Time, each share of SFC
Common Stock then issued and outstanding (excluding shares held by SFC, UPC, or
their respective subsidiaries, in each case other than shares held in a
fiduciary capacity or as a result of debts previously contracted) will be
converted into and exchanged for .7694 of a share of UPC Common Stock, subject
to possible adjustment as described below (the "Exchange Ratio"). It is
anticipated that as soon as practical following the Merger, SFC will merge with
and into UPC with UPC as the surviving corporation (the "Second Merger").
 
     No fractional shares of UPC Common Stock will be issued. Rather, cash
(without interest) will be paid in lieu of any fractional share interest to
which any SFC stockholder would be entitled upon consummation of the Merger, in
an amount equal to such fractional part of a share of UPC Common Stock
multiplied by the closing price of such common stock on the NYSE-Composite
Transactions List (as reported by The Wall Street Journal or, if not reported
thereby, another authoritative source as selected by UPC) on the last trading
day preceding the Effective Time.
 
     As of the SFC Record Date, SFC had 1,498,636 shares of SFC Common Stock
issued and outstanding and 149,946 additional shares of SFC Common Stock subject
to SFC Options. Based upon an Exchange Ratio of .7694, upon consummation of the
Merger, UPC would issue approximately 1,153,051 shares of UPC Common Stock,
excluding shares subject to assumed SFC Options. Accordingly, UPC would then
have issued and outstanding approximately 68,081,532 shares of UPC Common Stock
based on the number of shares of UPC Common Stock issued and outstanding on July
31, 1997 (and excluding shares to be issued pursuant to Other Pending
Acquisitions and shares to be issued pursuant to the exercise of stock options
and for other purposes).
 
POSSIBLE ADJUSTMENT OF EXCHANGE RATIO
 
     Under certain circumstances, the Exchange Ratio could be adjusted pursuant
to certain provisions in the Agreement; under no circumstances would the
Exchange Ratio be less than .7694 of a share of UPC Common Stock for each share
of SFC Common Stock. An adjustment could occur only if SFC's Board of Directors
elects by majority vote to terminate the Agreement pursuant to the provisions of
the Agreement described below, and if UPC then elects to avoid termination of
the Agreement by adjusting the Exchange Ratio.
 
     SFC is not obligated to consummate the Merger with UPC if both:
 
        (a) the average of the daily last sales prices (the "Average Closing
            Price") of UPC Common Stock (as reported on the NYSE Composite
            Transactions List) for the 20 consecutive full trading days ending
            on the later of the date on which the Special Meeting is held and
            the date on which the last required consent of the Board of
            Governors of the Federal Reserve or the Office of Thrift Supervision
            is received (the "Determination Date") is less than $41.50, which
            represents a 20% decline from $51.875 (the "Starting Price"), the
            price per share of UPC Common Stock on June 30, 1997, the fourth
            full trading day after the announcement by press release of the
            Merger (the "Starting Date");
 
        and
 
                                       16
<PAGE>   25
 
          (b) (i) the number (the "UPC Ratio") obtained by dividing the Average
              Closing Price by $51.875, the Starting Price, is less than (ii)
              the number (the "Index Ratio") obtained by dividing the weighted
              average of the closing prices of the common stock of the bank
              holding companies defined as the "Index Group" in the Agreement
              (the "Index Price") on the Determination Date by the Index Price
              on June 30, 1997, the Starting Date, less 15%.
 
     In such case, SFC has the right to terminate the Agreement during the
ten-day period commencing two days after the Determination Date by giving UPC
prompt notice of that decision. SFC may withdraw its termination notice at any
time during that ten-day period. During the five-day period after receipt of
such notice, UPC has the option to increase the consideration payable to SFC
stockholders by adjusting the Exchange Ratio in the manner described below. UPC
IS UNDER NO OBLIGATION TO ADJUST THE EXCHANGE RATIO. If UPC elects to adjust the
Exchange Ratio, it must give SFC prompt notice of that election and of the
adjusted Exchange Ratio, in which case no termination shall have occurred
pursuant to such right of termination.
 
     These conditions reflect the parties' agreement that SFC's stockholders
will assume the risk of declines in the value of UPC Common Stock to $41.50. Any
adjustment of the Exchange Ratio below a decline in the price of UPC Common
Stock to $41.50 would be dependent on whether the price of UPC Common Stock lags
behind a market basket of comparable bank holding company common stocks (the
Index Group referenced above) by more than 15%.
 
     If the Average Closing Price is less than $41.50 per share and the UPC
Ratio is less than the Index Ratio, the Board of Directors of SFC would likely
elect to terminate the Agreement so as to require UPC to consider increasing the
Exchange Ratio. UPC would then determine whether to proceed with the Merger at
the higher Exchange Ratio. In making this determination, the principal factors
UPC will consider include the projected effect of the Merger on UPC's pro forma
earnings per share and whether UPC's assessment of SFC's earning potential as
part of UPC justifies the issuance of an increased number of UPC's shares. If
UPC declines to adjust the Exchange Ratio, SFC may elect to proceed without the
adjustment, provided it does so within 12 days of the Determination Date,
although it has no intention to so elect without resoliciting stockholder
approval. In making such determination, the Board of Directors of SFC will
consider whether the Merger remains in the best interest of SFC and its
stockholders, despite a decline in UPC's stock price, and whether the
consideration to be received by the holders of SFC Common Stock remains fair
from a financial point of view.
 
     The operation of the adjustment mechanism can be illustrated by three
scenarios. (For purposes of the scenarios, it has been assumed that the initial
Exchange Ratio is .7694, the Starting Price of UPC Common Stock is $51.875, and
the Index Price, as of the Starting Date, is $100.)
 
        (1) The first scenario occurs if the Average Closing Price is not less
            than $41.50. Under this scenario, regardless of any comparison
            between the UPC Ratio and the Index Ratio, there would be no
            adjustment to the Exchange Ratio, even though the value of the
            consideration to be received by SFC stockholders could have fallen
            from a pro forma $39.91 per share, as of the Starting Date, to
            $31.93 per share, as of the Determination Date.
 
        (2) The second scenario occurs if the Average Closing Price is less than
            $41.50, but does not represent a decline from the Starting Price of
            significantly more (i.e., by more than 15%) than the decline of the
            common stock prices of the Index Group. Under this scenario, there
            also would be no adjustment to the Exchange Ratio, even though the
            value of the consideration to be received by SFC stockholders would
            have fallen from a pro forma $39.91 per share, as of the Starting
            Date, to an amount based on the then lower price per share of UPC
            Common Stock, as of the Determination Date.
 
        (3) The third scenario occurs if the Average Closing Price declines
            below $41.50 and the UPC Ratio is below the Index Ratio. Under
            this scenario, the adjustment in the Exchange Ratio is designed to
            ensure that the SFC stockholders receive shares of UPC Common
            Stock having a value (based upon the Average Closing Price) that
            corresponds to at least $31.93 or a 15% decline from the stock
            price performance reflected by the Index Group, whichever is less.
 
                                       17
<PAGE>   26
 
           For example, if the Average Closing Price were $41, and the ending
           Index Price, as of the Determination Date, were $95, the UPC Ratio
           (.79) would be below the Index Ratio (.80, or .95 minus .15), SFC
           could terminate the Agreement unless UPC elected within five days to
           increase the Exchange Ratio to equal .7788, which represents the
           lesser of (a) .7788 [the result of dividing $31.93 (the product of
           $41.50 and the .7694 Exchange Ratio) by the Average Closing Price
           ($41.00), rounded to the nearest thousandth] and (b) .779 [the result
           of dividing the Index Ratio (.80) times .7694 by the UPC Ratio (.79),
           rounded to the nearest thousandth]. Based upon the assumed $41.00
           Average Closing Price, the new Exchange Ratio would represent a value
           to the SFC stockholders of $31.93 per share.
 
           If the Average Closing Price were $41.00, and the ending Index Price,
           as of the Determination Date, were $100, the UPC Ratio (.79) would be
           below the Index Ratio (.85, or 1.00 minus .15), SFC could terminate
           the Agreement unless UPC elected within five days to increase the
           Exchange Ratio to equal .7788, which represents the lesser of (a)
           .7788 [the result of dividing $31.93 (the product of $41.50 and the
           .7694 Exchange Ratio) by the Average Closing Price ($41.00), rounded
           to the nearest thousandth] and (b) .828 [the result of dividing the
           Index Ratio (.85) times .7694 by the UPC Ratio (.79), rounded to the
           nearest thousandth]. Based upon the assumed $41.00 Average Closing
           Price, the new Exchange Ratio would represent a value to the SFC
           stockholders of $31.93 per share.
 
     The actual market value of a share of UPC Common Stock at the Effective
Time and at the time certificates for those shares are delivered following
surrender and exchange of Certificates for shares of SFC Common Stock may be
more or less than the Average Closing Price. SFC stockholders are urged to
obtain current market quotations for UPC Common Stock. See "COMPARATIVE MARKET
PRICES AND DIVIDENDS."
 
EFFECT OF THE MERGER ON SFC OPTIONS
 
     At the Effective Time, each SFC Option granted by SFC under the SFC Stock
Plans, as that term is defined in the Agreement, which are outstanding at the
Effective Time, whether or not exercisable, will be converted into and become
rights with respect to UPC Common Stock, and UPC will assume each SFC Option, in
accordance with the terms of the SFC Stock Plan and stock option or other
agreement by which it is evidenced, except that from and after the Effective
Time, (i) UPC and its Salary and Benefits Committee will be substituted for SFC
and the Committee of SFC's Board of Directors (including, if applicable, the
entire Board of Directors of SFC or other independent committee) administering
such SFC Stock Plan, (ii) each SFC Option assumed by UPC may be exercised solely
for or converted into shares of UPC Common Stock, (iii) the number of shares of
UPC Common Stock subject to such SFC Option (if applicable) will be equal to the
number of shares rounded down to the nearest whole share of SFC Common Stock
subject to such SFC Option immediately prior to the Effective Time multiplied by
the Exchange Ratio, and (iv) the per share exercise price under each such SFC
Option will be adjusted by dividing the per share exercise price under each such
SFC Option by the Exchange Ratio and rounding up to the nearest cent.
 
BACKGROUND OF AND REASONS FOR THE MERGER
 
     BACKGROUND OF THE MERGER.  Effective June 28, 1994, 1(st) Savings Bank
converted from a federally chartered mutual savings bank to a federally
chartered stock savings bank. At the same time, SFC was formed as 1(st) Savings
Bank's holding company. In connection with the conversion, SFC completed an
initial public offering of stock, selling 2,049,875 shares of SFC Common Stock
at $10.00 per share.
 
     Following the conversion, management of SFC focused its attention primarily
on increasing its core business while reviewing, from time to time, its
strategic alternatives in light of its size, the increasing consolidation of the
financial services industry and other relevant considerations. In January 1996,
the Board of Directors determined to maintain an informed position with respect
to its strategic alternatives by, among other things, retaining a financial
advisor.
 
                                       18
<PAGE>   27
 
     In January 1996, SFC engaged FBR, to serve as its financial advisor on
financial and strategic matters relating to the enhancement of stockholder
value. Throughout 1996 and the first quarter of 1997 several alternatives were
considered by SFC, most of which assumed the continued independence of SFC. None
of these alternatives were ultimately deemed to be acceptable, based on market,
pricing or regulatory issues.
 
     In January 1997, representatives of FBR presented an overview of several
strategic alternatives available to the Board of Directors of SFC. Among the
topics discussed was whether SFC should remain independent or consider a
business combination with a similar sized or larger institution; and, if SFC
were to seek a business combination, how it would develop and evaluate
opportunities. In late April 1997, representatives of FBR met with several
companies, including UPC, which had previously expressed interest in acquiring
SFC.
 
     On May 13, 1997, the Board of Directors of SFC met to discuss its strategic
alternatives. During this meeting, representatives of FBR presented analyses of
SFC's strategic options, including comparative estimates of the returns to
stockholders of SFC if, on one hand, SFC were to remain independent or, on the
other hand, SFC were to engage in a business combination with a larger
institution. At this meeting, the Board of Directors of SFC decided to determine
the level of interest that might exist for a strategic alliance on the part of
potential acquirors of SFC. The Board of Directors of SFC authorized FBR to
solicit indications of interest from certain prospective acquirors of SFC,
including UPC, which were believed by FBR to be likely to be interested in a
strategic alliance with SFC as part of the evaluation of SFC's strategic
alternatives.
 
     In late May 1997, President and Chief Executive Officer Raymond G.
Merryman, Executive Vice President David J. Tooley and Chief Financial Officer
Greg Steffens met informally with representatives of two different parties, one
of which was UPC. These meetings included a general discussion of potential deal
issues, with confidentiality agreements being executed by all parties. On-site
due diligence was performed by both parties during the first week of June 1997,
and on June 9, 1997, preliminary indications of interest were submitted by both
parties.
 
     FBR, on behalf of SFC, had subsequent discussions with both parties for the
purpose of enlarging the value of the stock consideration to be received by SFC
stockholders. However, neither party changed its indication of value of SFC.
 
     On June 11, 1997, the Board of Directors of SFC met to consider these
indications of interest. This meeting included representatives of Silver,
Freedman & Taff, L.L.P., SFC's outside legal counsel ("SFT") and FBR. The Board
of Directors of SFC determined, with the assistance of FBR, that UPC's
indication of interest represented the best economic and strategic alternative
for SFC and its stockholders. Various factors were considered in reaching this
conclusion including, among other things, the indicated and potential long term
value of the stock consideration from both parties, prevailing economic, market
and monetary conditions, the reasonableness and achievability of SFC's financial
and operating forecasts (and the assumptions and basis therefore) and its future
prospects as an independent institution, the future financial and operating
prospects of both parties that submitted preliminary indications of interest
after giving effect to a business combination involving an acquisition of SFC,
and the likely structures of the business combinations contemplated by the
preliminary indications of interest submitted by both parties.
 
     UPC's preliminary indication of interest contemplated that SFC would be
merged into a subsidiary of UPC, and was subject to a number of ordinary and
customary conditions regarding the negotiation of a definitive agreement and the
receipt of all relevant regulatory and stockholder approvals. Subsequent
discussions and negotiations over the next twelve days between UPC and its
counsel and SFC, its counsel and FBR, acting on behalf of SFC, resulted in a
formal offer for SFC, as set forth in the Agreement.
 
     On June 23, 1997, SFC's Board of Directors held a meeting that included the
participation of FBR and SFT. The meeting included a detailed discussion of the
proposed transaction and the proposed definitive agreement previously furnished
to the members of the Board of Directors of SFC. FBR presented a financial
analysis of the transaction and its opinion that the transaction was fair from a
financial point of view to the stockholders of SFC. SFC's Board then determined
that the proposed transaction with UPC was in the best interests of its
stockholders, and unanimously approved and adopted the Agreement and the Plan of
Merger including approval of the transactions contemplated thereby.

     SFC'S REASONS FOR THE MERGER.  The terms of the Agreement, including the
consideration to be paid to SFC stockholders, were the result of arm's length
negotiations between the representatives of UPC and SFC. Among the factors
considered by the Board of Directors of SFC in deciding to approve, adopt and
recommend the Agreement, the Plan of Merger and the transactions contemplated
thereby were:
 
          (a) the consideration to be paid to SFC stockholders in relation to
     the market value, book value, earnings per share and dividend rates of SFC
     Common Stock and UPC Common Stock;
 
          (b) information concerning the financial condition, results of
     operations, capital levels, asset quality and prospects of SFC and UPC;
 
          (c) the short-term and long-term impact the Merger will have on the
     UPC consolidated results of operations, including anticipated cost savings
     resulting from consolidations in certain areas;
 
          (d) the general structure of the transaction;
 
          (e) the compatibility of management and business philosophy;
 
          (f) the likelihood of receiving the requisite regulatory approvals in
     a timely manner;
 
          (g) the general tax-free nature of the Merger to stockholders of SFC;
 
          (h) the ability of the combined enterprise to compete in relevant
     banking and non-banking markets;
 
          (i) industry and economic conditions, including trends in the
     consolidation of the financial services industry;
 
          (j) the impact of the Merger on the depositors, employees, customers
     of and communities served by SFC through expanded consumer lending and
     retail banking products and services; and
 
          (k) the opinion of SFC's financial advisor as to the fairness, from a
     financial point of view, of the consideration to be paid to SFC
     stockholders.
 
     In adopting the Agreement and the Plan of Merger and approving the
transactions contemplated thereby, SFC's Board of Directors was aware that (i)
the Agreement contains certain provisions prohibiting SFC from soliciting other
offers to acquire SFC (see "-- Conduct of Business Pending the Merger") and (ii)
UPC would be able to exercise its rights under the Option Agreement in certain
circumstances generally relating to the failure of SFC to consummate the Merger
because of another offer for SFC or a material change or a potential material
change in the ownership of SFC (see "-- Option Agreement"). However, the SFC
Board of Directors was also aware that such terms were specifically bargained
for and insisted upon by UPC as inducements to enter into the Agreement, and
that the obligations of the SFC Board of Directors under the Agreement to
recommend that SFC stockholders adopt the Agreement and the Plan of Merger and
to use its reasonable efforts to obtain such adoption were explicitly made
subject to the fiduciary duties of the SFC Board of Directors as advised by
counsel to SFC. Accordingly, the Agreement expressly permits the SFC Board of
Directors, in the exercise of its fiduciary duties, to withdraw or change its
recommendation of the Agreement and the Plan of the Merger and to suspend or
terminate its efforts to obtain stockholder adoption of the Agreement and the
Plan of Merger at the Special Meeting (in such circumstances, however, UPC may
still be able to exercise its rights under the Option Agreement).
 
     The Board of Directors of SFC also considered that under the Agreement it
would have the right, in certain circumstances, to terminate the Agreement and
the Plan of Merger in the event of a significant decline in the price of UPC
Common Stock prior to consummation of the Merger unless UPC then elected to
increase the Exchange Ratio as specified in the Agreement. See "  -- Possible
Adjustment of Exchange Ratio."
 
     The foregoing discussion of the information and factors considered by SFC's
Board of Directors is not intended to be exhaustive but includes all material
factors considered by SFC's Board of Directors. In reaching its determination to
approve the Merger, SFC's Board of Directors did not assign any relative or
specific weights to different factors. After deliberating with respect to the
Merger and the other transactions contemplated thereby, and considering, among
other things, the matters discussed above and the opinion of
 
                                       20
<PAGE>   29
 
FBR referred to above, SFC's Board of Directors unanimously approved the
Agreement, the Plan of Merger and the transactions contemplated thereby,
including the Option Agreement, as being in the best interests of SFC and its
stockholders.
 
     SFC'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT SFC STOCKHOLDERS VOTE
FOR ADOPTION OF THE AGREEMENT AND THE PLAN OF MERGER.
 
     UPC'S REASONS FOR THE MERGER.  In adopting the Agreement, the Plan of
Merger, and the Merger, the UPC Board of Directors considered a number of
additional factors concerning the benefits of the Merger. Without assigning any
relative or specific weights to the factors, the UPC Board of Directors
considered the following additional material factors:
 
          (a) a review, based in part on a presentation by UPC's management, of
     (i) the business, operations, earnings, and financial condition, including
     the capital levels and asset quality, of SFC on an historical, prospective,
     and pro forma basis and in comparison to other financial institutions in
     the area, (ii) the demographic, economic, and financial characteristics of
     the markets in which SFC operates, including existing competition, history
     of the market areas with respect to financial institutions, and average
     demand for credit, on an historical and prospective basis, and (iii) the
     results of UPC's due diligence review of SFC; and
 
          (b) a variety of factors affecting and relating to the overall
     strategic focus of UPC, including UPC's desire to expand into markets in
     the general vicinity of its core markets.
 
     The Board of Directors of UPC determined that the Merger was in the best
interests of UPC and its stockholders and approved the Agreement on July 17,
1997.
 
OPINION OF SFC'S FINANCIAL ADVISOR
 
     Pursuant to a letter agreement initially entered into as of January 1996
and revised as of April 14, 1997 (the "FBR Agreement"), FBR was retained by SFC
to act as its financial advisor in connection with a review of SFC's strategic
alternatives. At the meeting of the SFC Board held on June 23, 1997, FBR
delivered its opinion to the SFC Board to the effect that as of the date of such
opinion, the proposed consideration to be received by the holders of shares of
SFC Common Stock pursuant to the Agreement is fair from a financial point of
view to such holders. FBR has reconfirmed its June 23, 1997 opinion by delivery
of its written opinion to the SFC Board, dated the date of this Proxy Statement
(the "FBR Opinion"), stating that, as of the date hereof and based on the
matters set forth in such opinion, the proposed consideration to be received by
the holders of shares of SFC Common Stock pursuant to the Agreement is fair to
such holders from a financial point of view.
 
     THE FULL TEXT OF THE FBR OPINION, WHICH SETS FORTH THE ASSUMPTIONS MADE,
PROCEDURES FOLLOWED, MATTERS CONSIDERED AND LIMITS ON THE REVIEW UNDERTAKEN, IS
ATTACHED AS APPENDIX C TO THIS PROXY STATEMENT AND IS INCORPORATED HEREIN BY
REFERENCE. THE DESCRIPTION OF THE FBR OPINION SET FORTH HEREIN IS QUALIFIED IN
ITS ENTIRETY BY REFERENCE TO APPENDIX C. SFC'S STOCKHOLDERS ARE URGED TO READ
THE FBR OPINION IN ITS ENTIRETY. FBR'S OPINION IS ADDRESSED ONLY TO SFC'S BOARD
OF DIRECTORS AND DIRECTED ONLY TO THE CONSIDERATION TO BE RECEIVED IN THE MERGER
BY THE HOLDERS OF SFC'S COMMON STOCK AND DOES NOT CONSTITUTE A RECOMMENDATION TO
ANY STOCKHOLDER AS TO HOW SUCH STOCKHOLDER SHOULD VOTE AT THE SPECIAL MEETING.
 
     FBR is a nationally recognized investment banking firm and was selected by
SFC based on the firm's reputation and experience in investment banking in
general, its recognized expertise in the valuation of banking businesses and
because of its familiarity with SFC. FBR, as part of its investment banking
business, is frequently engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements and valuations for corporate and other
purposes.
 
                                       21
<PAGE>   30
 
     In connection with rendering the opinions dated June 23, 1997, and the date
hereof, FBR, among other things: (i) reviewed the Agreement; (ii) reviewed the
Annual Reports to Stockholders of SFC for the fiscal years ended December 31,
1995 and 1996 and Annual Reports on Form 10-KSB of SFC for the fiscal years
ended December 31, 1995 and 1996, as well as quarterly reports on Form 10-QSB of
SFC for the three month periods ended September 30, 1996, March 31, 1997, and
June 30, 1997 and certain other communications from SFC to its stockholders;
(iii) reviewed UPC Annual Reports to Stockholders for the fiscal years ended
December 31, 1995 and 1996 and UPC Annual Reports on Form 10-K filed with the
SEC for the fiscal years ended December 31, 1994 through 1996, as well as
quarterly reports on Form 10-Q of UPC for the three month periods ended
September 30, 1996, March 31, 1997, and June 30, 1997; (iv) reviewed SFC's
unaudited financial statements for the five months ended May 31, 1997; (v)
reviewed the reported market prices and trading activity for UPC Common Stock
for the period January 1994 through June 23, 1997 and reviewed the reported
market prices and trading activity for SFC common stock for the period October
1, 1994 through June 23, 1997; (vi) discussed the financial condition, results
of operations, business and prospects of SFC and UPC with the managements of SFC
and UPC; (vii) compared the results of operations and financial condition of SFC
and UPC with those of certain publicly-traded financial institutions (or their
holding companies) that FBR deemed to be reasonably comparable to SFC or UPC, as
the case may be; (viii) participated in discussions and negotiations among
representatives of SFC and representatives of UPC; (ix) reviewed the financial
terms, to the extent publicly available, of certain acquisition transactions
that FBR deemed to be reasonably comparable; (x) reviewed the financial terms,
to the extent publicly available, of certain acquisition transactions entered
into by UPC; (xi) performed such other analyses and reviewed and analyzed such
other information as FBR deemed appropriate.
 
     In connection with rendering the FBR Opinion, FBR assumed and relied upon,
without independent verification, the accuracy and completeness of all the
financial information, analyses and other information reviewed by and discussed
with it, and did not make an independent evaluation or appraisal of the specific
assets, the collateral securing assets or the liabilities of UPC or SFC or any
of their subsidiaries, or the collectibility of any such assets (relying, where
relevant, on the analyses and estimates of UPC and SFC). With respect to the
financial projections reviewed with each company's management, FBR assumed that
they reflect the best currently available estimates and judgments of the
respective managements of the respective future financial performances of each
of UPC and SFC and of the combined company, and that such performances will be
achieved. FBR also assumed that there has been no material change in UPC's or
SFC's assets, financial condition, results of operations, business or prospects
since the date of the last financial statements noted above. FBR also assumed
without independent verification that the aggregate consolidated allowances for
loan losses for SFC and UPC were adequate to cover such losses, and that the
conditions precedent in the Agreement are not waived.
 
     No limitations were imposed on FBR by the SFC Board with respect to the
investigation made or procedures followed by FBR in rendering its fairness
opinion dated June 23, 1997. In connection with rendering such fairness opinion
to the SFC Board, FBR performed a variety of financial analyses. The following
is a summary of the material financial analyses performed by FBR, but does not
purport to be a complete description of FBR's analyses or presentation at the
June 23, 1997 meeting of the SFC Board. FBR believes that its analyses must be
considered as a whole and that selecting portions of such analyses and the
factors considered therein, without considering all factors and analyses, could
create an incomplete view of the analyses and the processes underlying the
fairness opinion of FBR dated June 23, 1997. The preparation of a fairness
opinion is a complex process involving subjective judgments and is not
necessarily susceptible to partial analyses or summary description. In its
analyses, FBR made numerous assumptions with respect to industry performance,
business and economic conditions and various other matters, many of which are
beyond the control of SFC and UPC. Any estimates contained in FBR's analyses are
not necessarily indicative of future results or values, which may be
significantly more or less favorable than such estimates. Estimates of values of
companies do not purport to be appraisals or necessarily reflect the prices at
which the companies or their securities may actually be sold.
 
     Summary of Terms of Proposed Transactions.  FBR reviewed the terms of the
proposed Merger, including the aggregate amount of consideration, the form of
consideration, and the percentage of premium to
 
                                       22
<PAGE>   31
 
the current market price. The amount of consideration is $39.34 per share of SFC
Common Stock to be paid in UPC Common Stock (the "Consideration") based on an
exchange ratio of .7694 and a price per share of $51.125 for UPC Common Stock
(the closing price for such stock on June 23, 1997).
 
     FBR stated that the Consideration as of June 23, 1997 represented a
multiple of (i) 24.7 times SFC's earnings per share for the twelve months ended
March 31, 1997; (ii) 17.5 times the I/B/E/S International, Inc. analyst's
estimate of SFC's 1997 earnings per share; (iii) 2.08 times SFC's book value per
share as of March 31, 1997 and (iv) 2.08 times March 31, 1997 tangible book
value per share. The Consideration also represented a tangible book premium to
core deposits of 19.56 percent based on tangible book value per share at March
31, 1997.
 
     The actual earnings results for SFC for the twelve months ended December
31, 1996 and March 31, 1997 included a nonrecurring expense of $901,000 for the
recapitalization of the Savings Association Insurance Fund taken in the third
quarter of 1996. The forecasts and projections furnished to FBR for SFC were
prepared by the management of SFC. As a matter of policy, SFC does not publicly
disclose internal management forecasts, projections or estimates of the type
furnished to FBR in connection with its analysis of the Merger, and such
forecasts, projections and estimates were not prepared with a view towards
public disclosure. These forecasts, projections and estimates were based on
numerous variables and assumptions which are inherently uncertain and which may
not be within the control of management including, without limitation, general
economic, regulatory and competitive conditions. Accordingly, actual results
could vary materially from those set forth in such forecasts, projections and
estimates.
 
     Comparable Transaction Analysis.  FBR reviewed certain information relating
to transactions announced since January 1, 1996 involving the acquisition of
thrifts nationwide ("Nationwide Transactions"), thrifts in Missouri ("Missouri
Transactions"), thrifts in Iowa, Illinois, Indiana, Kansas, Missouri and
Oklahoma ("Midwest Transactions") and thrifts nationwide with assets between
$200 million and $400 million (the "Asset Comparable Transactions")
(collectively, the "Comparable Groups"). It should be noted that the individual
Comparable Groups are not mutually exclusive of one another. In conjunction with
its analysis, FBR reviewed valuation multiples based on price to book value,
price to tangible book value, price to latest twelve months earnings per share
and the premium over tangible book value as a percentage of core deposits. FBR
compared UPC's pending acquisition of SFC to transactions involving the
Comparable Groups over the period from January 1, 1996 through August 8, 1997.
FBR also computed the foregoing ratios for the Merger assuming a price per share
of SFC Common Stock in the Merger of $39.34, based on an exchange ratio of
0.7694 and a price per share of $51.125 for UPC Common Stock (the closing price
for such stock on June 23, 1997). The Comparable Groups included the following
numbers of transactions: Nationwide Transactions (153), the Missouri
Transactions (6), the Midwest Transactions (23) and Asset Comparable
Transactions (24). FBR's computations yielded the following median multiples for
the Nationwide Transactions, the Missouri Transactions, the Midwest Transactions
and Asset Comparable Transactions, respectively, as compared with the following
indicated multiples for SFC in the Merger: (i) price to book value multiples of
1.52x, 1.31x, 1.48x and 1.82x, compared with 2.08x for the Merger; (ii) price to
tangible book value multiples of 1.60x, 1.31x, 1.48x and 1.82x, compared with
2.08x for the Merger; (iii) price to latest twelve months earnings multiples of
18.7x, 25.4x, 22.52x and 23.70x, compared with 24.7x for the Merger; and (iv)
core deposit premiums of 7.57%, 12.82%, 6.64% and 10.76%, compared with an
indicated deposit premium in the Merger of 19.56%.
 
     Discounted Earnings Stream and Terminal Value Analysis.  Using a discounted
earnings stream and terminal value analysis, FBR estimated the future stream of
earnings flows that SFC could be expected to produce through the year 2000,
under various circumstances, assuming SFC performed in accordance with the
earnings forecasts of SFC management. To approximate the terminal value of the
SFC Common Stock at the end of a four-year period (December 31, 2000), FBR
applied price to earnings multiples ranging from 15.5 to 18.0, applied multiples
of tangible book value ranging from 180 percent to 205 percent and applied
premiums over tangible book value as a percentage of core deposits of 10.0
percent to 15.0 percent. The net income streams and terminal values were then
discounted to present values using a discount rate of 15 percent. This analysis
assumed that SFC will continue its policy of not paying cash dividends and
indicated a total reference range of between $28.54 and $38.97 per share of SFC
Common Stock. When a 15 percent discount rate was
 
                                       23
<PAGE>   32
 
applied to median merger multiples based on the price to tangible book value
multiples of 180 to 205 percent, the analysis indicated a reference range
between $31.93 and $38.97 per share of SFC Common Stock. When the same discount
rate of 15 percent was applied to merger market multiples based on price to
earnings per share multiples of 15.5 times to 18.0 times, the analysis indicated
a reference range between $29.32 and $38.75 per share of SFC Common Stock. When
the same discount rate of 15 percent was applied to merger market multiples
based on tangible book premium to core deposits of 10.0 percent and 15.0
percent, the analysis indicated a reference range between $28.54 and $37.54 per
share of SFC Common Stock.
 
     Pro Forma Merger Analysis.  FBR performed pro forma merger analyses that
combined SFC's and UPC's current and projected income statement and balance
sheets based on earnings forecasts of SFC and UPC, respectively. Assumptions and
analyses of the accounting treatment, acquisition adjustments, operating
efficiencies and other adjustments were made to arrive at a base case pro forma
analysis to determine the effect of the transaction on both SFC and UPC. FBR
noted that, based on a fixed exchange ratio of .7694 shares of UPC Common Stock
for each share of SFC Common Stock, the impact of the Merger on UPC's earnings
per share and tangible book value per share based on such earnings forecasts did
not appear to be material. The actual results achieved by the combined company
will vary from the projected results and such variations may be material.
 
     Analysis of Selected Publicly Traded Companies.  In preparing its
presentation, FBR used publicly available information to compare selected
financial and market trading information, including book value, tangible book
value, earnings, asset quality ratios, loan loss reserve levels, profitability
and capital adequacy, for UPC and selected other publicly traded regional
commercial banks located in the Midwest and Southeast United States. This peer
group consisted of commercial bank holding companies with total assets between
$10 billion and $20 billion. Additionally, FBR used similar data for nationwide
high-performing commercial banks in the same asset range that had a return on
equity for the last fiscal quarter greater than 12 percent and a
price-to-tangible book value greater than 225 percent. FBR reviewed the
historical financial information for UPC and each member of the peer group since
December 31, 1991.
 
     In connection with rendering the FBR Opinion, FBR confirmed the
appropriateness of its reliance on the analyses used to render its June 23, 1997
opinion by performing procedures to update certain of such analyses and by
reviewing the assumptions upon which such analyses were based and the factors
considered in connection therewith. The FBR Opinion is necessarily based on
economic, market and other conditions as in effect on, and the information made
available to it as of, the date of such opinion. Events occurring after the date
of the FBR Opinion could materially affect the assumptions used in preparing
such opinion.
 
     Pursuant to the FBR Agreement, SFC retained FBR to act as independent
financial advisor, to render general advisory services and also to specifically
advise SFC in connection with its strategic planning and merger and acquisition
activities. Pursuant to SFC's Agreement with FBR, SFC is obligated to pay FBR
nonrefundable quarterly retainer fees of $6,250. SFC has paid such quarterly
retainer fee for the calendar quarter ended June 30, 1997. In addition, SFC's
agreement with FBR provides for an incentive-based fee on an escalating
percentage of the aggregate consideration to be paid to the Company's
stockholders. For its services as financial advisor to SFC in connection with
the Merger, FBR will receive a transaction fee equal to approximately 1.44% of
the aggregate consideration paid to SFC's stockholders and option holders (the
"Transaction Fee"). Twenty-five percent (25%), or $266,226, was paid upon the
signing of the Agreement and the remaining portion is payable at the closing of
the Merger. Based on the closing price of UPC Common Stock as of June 23, 1997,
the remaining portion of the transaction fee payable to FBR at the Effective
Time would be $798,679. SFC also has agreed to reimburse FBR for its reasonable
out-of-pocket expenses in connection with its engagement and to indemnify FBR
and its affiliates and their respective partners, directors, officers,
employees, agents and controlling persons against certain expenses and
liabilities, including liabilities under securities laws.
 
     FBR has advised SFC that, in the ordinary course of its business as a
full-service securities firm, FBR may, subject to certain restrictions, actively
trade the equity securities of SFC and/or UPC for its own account or for the
accounts of its customers, and, accordingly, may at any time hold a long or
short position in such securities.

EFFECTIVE TIME OF THE MERGER
 
     Subject to the conditions to the obligations of the parties to effect the
Merger, the Effective Time will occur on the date and at the time that the
Certificate of Merger reflecting the Merger becomes effective with the Secretary
of State of the State of Delaware. Unless otherwise agreed upon in writing by
UPC and SFC, and subject to the terms and conditions of the Agreement, the
parties will use their reasonable efforts to cause the Effective Time to occur
on such date as may be designated by UPC within 30 days following the last to
occur of (i) the effective date (including the expiration of any applicable
waiting period) of the last consent of any regulatory authority having authority
over and approving or exempting the Merger, (ii) the date on which the
stockholders of SFC approve the matters relating to this Agreement and the Plan
of Merger to the extent such approval is required stockholder by applicable law,
and (iii) the date on which all other conditions precedent to each party's
obligations under the Agreement have been satisfied or waived (to the extent
waivable).
 
     No assurance can be provided that the necessary stockholder and regulatory
approvals can be obtained or that other conditions precedent to the Merger can
or will be satisfied. SFC and UPC anticipate that all conditions to consummation
of the Merger will be satisfied so that the Merger can be consummated during the
first quarter of 1998. However, delays in the consummation of the Merger could
occur.
 
     The Board of Directors of either SFC or UPC generally may terminate the
Agreement and the Plan of Merger if the Merger is not consummated by June 30,
1998, unless the failure to consummate the transactions contemplated by the
Agreement on or before such date is caused by any willful breach of the
Agreement by the party seeking termination. See " -- Conditions to Consummation
of the Merger" and " -- Waiver, Amendment, and Termination."
 
DISSENTERS' RIGHTS
 
     Pursuant to DGCL Section 262, the holders of SFC Common Stock do not have
dissenters' rights with respect to the Merger.
 
DISTRIBUTION OF UPC STOCK CERTIFICATES
 
     Promptly after the Effective Time, UPC and SFC will cause Union Planters
National Bank, Memphis, Tennessee, acting in its capacity as Exchange Agent, to
mail to the former stockholders of SFC a letter of transmittal, together with
instructions for the exchange of the Certificates representing shares of SFC
Common Stock for certificates representing shares of UPC Common Stock.
 
     SFC STOCKHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY RECEIVE
THE LETTER OF TRANSMITTAL AND INSTRUCTIONS.
 
     Upon surrender to the Exchange Agent of Certificates for SFC Common Stock,
together with a properly completed letter of transmittal, there will be issued
and mailed to each holder of SFC Common Stock surrendering such items a
certificate or certificates representing the number of shares of UPC Common
Stock to which such holder is entitled and a check for the amount to be paid in
lieu of any fractional share (without interest), if any, together with all
undelivered dividends or distributions in respect of such shares (without
interest thereon), if any. UPC will not be obligated to deliver the
consideration to which any former holder of SFC Common Stock is entitled as a
result of the Merger until the holder surrenders such holder's Certificates
representing the shares of SFC Common Stock. Whenever a dividend or other
distribution is declared by UPC on UPC Common Stock, the record date for which
is at or after the Effective Time, the declaration will include dividends or
other distributions on all shares issuable pursuant to the Agreement, but no
dividend or other distribution payable after the Effective Time with respect to
UPC Common Stock will be paid to the holder of any unsurrendered SFC Common
Stock Certificate until the holder duly surrenders such Certificate. Upon
surrender of such SFC Common Stock Certificate, however, both the UPC Common
Stock certificate, together with all undelivered dividends or other
distributions (without interest) and any undelivered cash payment to be paid in
lieu of a fractional share (without interest), will be delivered and paid with
respect to the shares represented by such Certificate.
 
                                       25
<PAGE>   34
 
     At the Effective Time, the stock transfer books of SFC will be closed to
holders of SFC Common Stock immediately prior to the Effective Time and there
will be no transfer of shares of SFC Common Stock on SFC's stock transfer books.
If Certificates representing shares of SFC Common Stock are presented for
transfer after the Effective Time, they will be canceled and exchanged for the
shares of UPC Common Stock and a check for the amount due in lieu of fractional
shares and undelivered dividends, if any, deliverable in respect thereof.
 
CONDITIONS TO CONSUMMATION OF THE MERGER
 
     Consummation of the Merger is subject to various conditions, including (i)
receipt of the approval of the stockholders of SFC of the Agreement and the Plan

provisions of any governing instrument or by the rules of the National
Association of Securities Dealers, Inc. ("NASD"), (ii) receipt of certain
regulatory approvals required for consummation of the Merger, (iii) receipt of a

law or order or any action taken by any court, governmental, or regulatory
authority prohibiting, restricting, or making illegal the consummation of the
transaction; (x) receipt by UPC of agreements from each affiliate of SFC; and
(xi) satisfaction of certain other conditions, including the receipt of certain
legal opinions and various certificates from the officers of SFC and UPC. See
"-- Regulatory Approvals" and " -- Waiver, Amendment, and Termination."
 
     No assurance can be provided as to when or if all of the conditions
precedent to the Merger can or will be satisfied or waived by the party
permitted to do so. In the event the Merger is not effected on or before June
30, 1998, the Agreement may be terminated and the Merger abandoned by a vote of
a majority of the Board of Directors of either SFC or UPC. See "-- Waiver,
Amendment, and Termination."
 
REGULATORY APPROVAL
 
     THE MERGER MAY NOT PROCEED IN THE ABSENCE OF RECEIPT OF THE REQUISITE
REGULATORY APPROVALS. THERE CAN BE NO ASSURANCE THAT SUCH REGULATORY APPROVALS
WILL BE OBTAINED OR AS TO THE TIMING OF SUCH APPROVALS. APPLICATIONS FOR THE
APPROVALS DESCRIBED BELOW HAVE BEEN SUBMITTED TO THE APPROPRIATE REGULATORY
AUTHORITIES.
 
     It is a condition to the consummation of the Merger that UPC and SFC shall
have received all applicable regulatory approvals to consummate the transactions
contemplated by the Agreement, without the imposition of any condition which in
the reasonable judgment of the Board of Directors of UPC would so materially
adversely impact the financial or economic benefits of the transactions
contemplated by the Agreement that, had such condition or requirement been
known, UPC would not, in its reasonable judgment, have entered into the
Agreement. There can be no assurance that such approvals will not contain terms,
conditions or requirements which cause such approvals to fail to satisfy such
condition to the consummation of the Merger.
 
     SFC and UPC are not aware of any material governmental approvals or actions
that are required for consummation of the Merger, except as described below.
Should any other approval or action be required, it presently is contemplated
that such approval or action would be sought.
 
     The Merger is subject to the prior approval of the Federal Reserve,
pursuant to Section 3 of the BHC Act. In evaluating the Merger, the Federal
Reserve must consider, among other factors, the financial and managerial
resources and future prospects of the institutions and the convenience and needs
of the
 
                                       26
<PAGE>   35
 
communities to be served. The relevant statutes prohibit the Federal Reserve
from approving the Merger if (i) it would result in a monopoly or be in
furtherance of any combination or conspiracy to monopolize or attempt to
monopolize the business of banking in any part of the United States or (ii) its
effect in any section of the country may be to substantially lessen competition
or to tend to create a monopoly, or if it would result in a restraint of trade
in any other manner, unless the Federal Reserve should find that any
anticompetitive effects are outweighed clearly by the public interest and the
probable effect of the transaction in meeting the convenience and needs of the
communities to be served. The Merger may not be consummated until the 30th day
(which the Federal Reserve may reduce to 15 days) following the date of the
Federal Reserve approval, during which time the United States Department of
Justice would be afforded the opportunity to challenge the transaction on
antitrust grounds. The commencement of any antitrust action would stay the
effectiveness of the approval of the agencies, unless a court of competent
jurisdiction should specifically order otherwise.
 
WAIVER, AMENDMENT, AND TERMINATION
 
     To the extent permitted by law, the Agreement may be amended by a
subsequent writing signed by each of the parties upon the approval of the Boards
of Directors of each of the parties, whether before or after stockholder
adoption of the Agreement and the Plan of Merger has been obtained; provided,
that after any such adoption by the holders of SFC Common Stock, there shall be
made no amendment that modifies in any material respect the consideration to be
received by the holders of SFC Common Stock without the further approval of such
stockholders. In addition, prior to or at the Effective Time, either SFC or UPC,
or both, acting through their respective Boards of Directors, chief executive
officers, or other authorized officers may waive any default in the performance
of any term of the Agreement by the other party, may waive or extend the time
for the compliance or fulfillment by the other party of any and all of its
obligations under the Agreement, and may waive any of the conditions precedent
to the obligations of such party under the Agreement, except any condition that,
if not satisfied, would result in the violation of any applicable law or
governmental regulation. No such waiver will be effective unless written and
unless executed by a duly authorized officer of SFC or UPC, as the case may be.
 
     The Agreement and the Plan of Merger may be terminated and the Merger
abandoned at any time prior to the Effective Time (i) by the mutual consent of
the Boards of Directors of SFC and UPC; (ii) by the Board of Directors of SFC or
UPC (a) in the event of any inaccuracy of any representation or warranty of the
other party contained in the Agreement which cannot be or has not been cured
within 30 days after giving written notice to the breaching party of such
inaccuracy and which inaccuracy would provide the terminating party the ability
to refuse to consummate the Merger under the applicable standards set forth in
the Agreement (provided that the terminating party is not then in breach of any
representation or warranty contained in the Agreement under the applicable
standards set forth in the Agreement or in material breach of any covenant or
other agreement contained in the Agreement), (b) in the event of a material
breach by the other party of any covenant or agreement contained in the
Agreement which cannot be or has not been cured within 30 days after the giving
of written notice to the breaching party of such breach (provided that the
terminating party is not then in breach of any representation or warranty
contained in the Agreement under the applicable standards set forth in the
Agreement or in material breach of any covenant or other agreement contained in
the Agreement), (c) if the Merger is not consummated by June 30, 1998, provided
that the failure to consummate is not caused by any willful breach of the
Agreement by the party electing to terminate, (d) if (1) any consent of any
regulatory authority required for consummation of the Merger and the other
transactions contemplated by the Agreement has been denied by final
nonappealable action, or if any action taken by such authority is not appealed
within the time limit for appeal or (2) the stockholders of SFC fail to vote
their approval of the matters submitted for the approval by such stockholders at
the Special Meeting, or (e) if any of the conditions precedent to the
obligations of such party to consummate the Merger cannot be satisfied,
fulfilled, or waived by the appropriate party by June 30, 1998 (provided that
the terminating party is not then in breach of any representation or warranty
contained in the Agreement under the applicable standards set forth in the
Agreement or in material breach of any covenant or other agreement contained in
the Agreement); or (iii) by the Board of Directors of SFC pursuant to the
relevant provisions of the Agreement described in " -- Possible Adjustment of
Exchange Ratio."

     If the Merger is terminated as described above, the Agreement and the Plan
of Merger will become void and have no effect, except that certain provisions of
the Agreement, including those relating to the obligations to share certain
expenses, maintain the confidentiality of certain information obtained, and
return all documents obtained from the other party under the Agreement, will
survive. In addition, termination of the Agreement will not relieve any
breaching party from liability for any uncured willful breach of a
representation, warranty, covenant, or agreement giving rise to such
termination. The Option Agreement will be governed by its own terms as to its
termination. See " -- Expenses and Fees" and " -- Option Agreement."
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
     Pursuant to the Agreement, SFC has agreed that unless the prior written
consent of UPC has been obtained, and except as otherwise expressly contemplated
in the Agreement each of SFC and its subsidiaries will (i) operate its business
only in the usual, regular, and ordinary course, (ii) preserve intact its
business organization and assets and maintain its rights and franchises, and
(iii) take no action which would (a) materially adversely affect the ability of
any party to obtain any consents required for the transactions contemplated by
the Agreement without imposition of a condition or restriction of the type
referred to in the Agreement or prevent the transactions contemplated by the
Agreement, including the Merger, from qualifying as a reorganization within the
meaning of Section 368(a) of the Code (see " -- Certain Federal Income Tax
Consequences"), or (b) materially adversely affect the ability of any party to
perform its covenants and agreements under the Agreement.
 
     In addition, SFC has agreed that, except as specifically contemplated by
the Agreement or other documents or instruments executed in connection with the
Agreement, prior to the earlier of the Effective Time or termination of the
Agreement, SFC will not, except with the prior written consent of the chief
executive officer, president, or chief financial officer of UPC (which consent
shall not be unreasonably withheld), agree or commit to do, or permit any of its
subsidiaries to agree or commit to do, any of the following: (i) amend the
Charter, Bylaws, or other governing instruments of SFC or any SFC subsidiary
(each a "SFC company" and together, the "SFC companies"); (ii) incur any
additional debt obligation or other obligation for borrowed money (other than
indebtedness of a SFC company to another SFC company) in excess of an aggregate
of $250,000 (for the SFC companies on a consolidated basis) except in the
ordinary course of business of the SFC subsidiaries consistent with past
practices (which shall include, for SFC subsidiaries that are depository
institutions, the creation of deposit liabilities, purchases of federal funds,
advances from the Federal Reserve Bank or the Federal Home Loan Bank, and entry
into repurchase agreements fully secured by U.S. government or agency
securities), or impose, or suffer the imposition, on any asset of any SFC
company of any lien or permit any such lien to exist (other than in connection
with deposits, repurchase agreements, bankers acceptances, advances from the
Federal Reserve Board or Federal Home Loan Bank, "treasury tax and loan"
accounts established in the ordinary course of business, the satisfaction of
legal requirements in the exercise of trust powers, and liens in effect as of
the date of the Agreement that were previously disclosed to UPC by SFC); (iii)
repurchase, redeem, or otherwise acquire or exchange (other than exchanges in
the ordinary course under employee benefit plans), directly or indirectly, any
shares, or any securities convertible into any shares, of the capital stock of
any SFC company, or declare or pay any dividend or make any other distribution
in respect of any SFC capital stock; (iv) except pursuant to the Agreement, or
pursuant to the exercise of stock options or stock rights outstanding as of the
date of the Agreement, or pursuant to the Option Agreement, issue, sell, pledge,
encumber, authorize the issuance of, enter into any contract to issue, sell,
pledge, encumber, or authorize the issuance of, or otherwise permit to become
outstanding, any additional shares of SFC Common Stock, or any other capital
stock of any SFC company, or any stock appreciation rights, or any option,
warrant, conversion, or other right to acquire any such stock, or any security
convertible into any such stock; (v) adjust, split, combine, or reclassify any
capital stock of any SFC company or issue or authorize the issuance of any other
securities in respect of or in substitution for shares of SFC Common Stock or
sell, lease, mortgage, or otherwise dispose of or otherwise encumber any shares
of capital stock of any SFC subsidiary (unless any such shares of stock are sold
or otherwise transferred to another SFC company) or any assets having a book
value in excess of $250,000 other than in the ordinary course of business for
reasonable and adequate consideration; (vi) except for purchases of U.S.
Treasury securities, U.S. Government agency securities, municipal bands, local
tax exempt securities, or other securities
 
                                       28

which in any case have maturities of five years or less, which purchases are
consistent with past practices, or Federal Home Loan Bank stock, purchase any
securities or make any material investment, either by purchase of stock or
securities, contributions to capital, asset transfers, or purchase of any
assets, in any person other than a wholly-owned SFC subsidiary, or otherwise
acquire direct or indirect control over any person, with certain exceptions;
(vii) grant any increase in compensation or benefits to the employees or
officers of any SFC company, except in accordance with past practices as
previously disclosed to UPC by SFC or as required by law; pay any severance or
termination pay or any bonus other than pursuant to written policies or written
contracts in effect on the date of the Agreement and previously disclosed to UPC
by SFC; enter into or amend any severance agreements with officers of any SFC
company; or grant any material increase in fees or other increases in
compensation or other benefits to directors of any SFC company except in
accordance with past practices as previously disclosed to UPC by SFC; (viii)
except as previously disclosed, voluntarily accelerate the vesting of any stock
options or other stock-based compensation or employee benefits other than the
acceleration of vesting which occurs under a benefit plan upon a change of
control of SFC; (ix) enter into or amend any employment contract between any SFC
company and any person (unless such amendment is required by law) that the SFC
company does not have the unconditional right to terminate without liability
(other than liability for services already rendered), at any time on or after
the Effective Time; (x) except as previously disclosed by SFC or otherwise
agreed by the parties, adopt any new employee benefit plan of any SFC company or
make any material change in or to any existing employee benefit plans of any SFC
company other than any such change that is required by law or that, in the
opinion of counsel, is necessary or advisable to maintain the tax qualified
status of any such plan, or make any distribution from such employee benefit
plans, except as required by law, the terms of the plans, or consistent with
past practices; (xi) make any significant change in any tax or accounting
methods or systems of internal accounting controls, except as may be appropriate
to conform to changes in tax laws or regulatory accounting requirements or
generally accepted accounting principles; (xii) commence any litigation other
than in accordance with past practice or settle any litigation involving any
liability of any SFC company for money damages in excess of $100,000 or
restrictions upon the operations of any SFC company; or (xiii) other than in the
ordinary course of business consistent with past practice or as otherwise
previously disclosed by SFC, enter into, modify, amend or terminate any material
contract (excluding any loan contract) or waive, release, compromise or assign
any material rights or claims.
 
     SFC has also agreed that, except with respect to the Agreement, the Plan of
Merger and the transactions contemplated thereby, no SFC company or any
affiliate thereof shall directly or indirectly solicit any acquisition proposal
or, except to the extent necessary to comply with the fiduciary duties of SFC's
Board of Directors as advised by counsel, furnish any non-public information
that it is not legally obligated to furnish, negotiate with respect to, or enter
into any contract with respect to, any acquisition proposal, but SFC may
communicate information about such an acquisition proposal to its stockholders
if and to the extent that it is required to do so in order to comply with its
legal obligations as advised by counsel.
 
     The Agreement also provides that from the date of the Agreement until the
earlier of the Effective Time or the termination of the Agreement, UPC covenants
and agrees that it will (i) continue to conduct its business and the business of
its subsidiaries in a manner designed in its reasonable judgment, to enhance the
long-term value of the UPC Common Stock and the business prospects of UPC or its
subsidiaries and (ii) take no action which would (a) materially adversely affect
the ability of any party to obtain any consents required for the transactions
contemplated by the Agreement without imposition of a condition or restriction
of the type referred to in the Agreement or prevent the transactions
contemplated by the Agreement, including the Merger, from qualifying as a
reorganization within the meaning of Section 368(a) of the Code (see "-- Certain
Federal Income Tax Consequences"), or (b) materially adversely affect the
ability of any party to perform its covenants and agreements under the
Agreement.
 
MANAGEMENT AND OPERATIONS AFTER THE MERGER
 
     Consummation of the Merger will not alter the present management team or
Board of Directors of UPC. Information concerning the management of UPC is
included in the documents incorporated herein by
 
                                       29
<PAGE>   38
 
reference. See "DOCUMENTS INCORPORATED BY REFERENCE." For additional information
regarding the interests of certain persons in the Merger, see "-- Interests of
Certain Persons in the Merger."
 
     SFC will be the surviving corporation resulting from the Merger and shall
continue to be governed by the laws of the State of Delaware and operate in
accordance with its Certificate of Incorporation ("SFC's Certificate") and
Bylaws as in effect on the date hereof, and immediately prior to the Effective
Time, until otherwise amended or repealed after the Effective Time.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     GENERAL.  Certain members of SFC's management and SFC's Board of Directors
have interests in the Merger that are in addition to any interests they may have
as stockholders of SFC generally. As more fully described below, these interests
relate to, among other things, provisions in the Agreement regarding
indemnification, eligibility for certain employee benefits and certain other
benefits.
 
     POST-MERGER MANAGEMENT MATTERS.  UPC has agreed to cause David J. Tooley,
Executive Vice President and a member of the Board of Directors of SFC and 1(st)
Savings Bank, to be appointed to the Board of Directors of the UPC subsidiary
operating in Springfield, Missouri. At or prior to the Effective Time, through
July 31, 2001, UPC has also agreed to maintain a Mt. Vernon, Missouri Advisory
Board (the "Advisory Board") consisting of any director or advisory director of
SFC as of the Effective Time, and any executive officer of SFC whose employment
is terminated at or after the Effective Time. Such Advisory Board shall meet at
least twice a year, as determined by UPC, and its members will be paid $100 per
meeting attended.
 
     UPC has further agreed that it shall assume all of the obligations of SFC
and 1(st) Savings Bank under those certain Change In Control Severance
Agreements between each of Raymond G. Merryman, David J. Tooley and Greg
Steffens and 1(st) Savings Bank dated December 18, 1996 (the "Severance
Agreements"). UPC acknowledges that the consummation of the Merger will
constitute both a change in control and a termination of employment under the
Severance Agreements. The estimated amounts which will be payable under such
Severance Agreements to Messrs. Merryman, Tooley and Steffens are $214,973,
$217,833 and $130,117, respectively. In consideration of their individual
receipt of an additional $50,000, each of Raymond G. Merryman and David J.
Tooley have agreed to enter into a written agreement not to compete with UPC in
any of those banking and related financial services business activities in which
the SFC companies are involved in as of the Effective Time, for a period of two
years following the Effective Time in Lawrence, Cedar, Greene or Polk Counties,
Missouri or any contiguous county.
 
     SFC OPTIONS AND RESTRICTED STOCK.  SFC has granted the SFC Options and
restricted stock to its executive officers, employees and directors under the
Sho-Me Financial Corp. 1994 Stock Option and Incentive Plan and the Sho-Me
Financial Corp. Management Recognition Plan, respectively (collectively, the
"SFC Stock Plans"). The Agreement provides that UPC will assume any outstanding
option or other rights with respect to SFC Common Stock, whether vested or
unvested, which have been granted or acquired under the SFC Stock Plans on a
basis reflecting the Exchange Ratio.
 
     The following table sets forth with respect to the directors and executive
officers of SFC as a group the number of shares of SFC Common Stock covered by
outstanding stock options held by such group as of August 25, 1997.

    Directors and Executive Officers as a Group (six persons)............         25,018
</TABLE>
 
     Such shares will continue to vest under the current vesting schedule so
long as the directors and executive officers continue to be employed by UPC or
members of the Advisory Board after the Effective Time.
 
     OTHER MATTERS RELATING TO SFC EMPLOYEE BENEFIT PLANS.  The Agreement also
provides that, after the Effective Time, UPC will provide to officers and
employees of the SFC companies who, at or after the Effective Time, become
officers or employees of a UPC company, employee benefits under employee benefit
and welfare plans, on terms and conditions which when taken as a whole are
substantially similar to those currently provided by the UPC companies to their
similarly situated officers and employees. For purposes of participation,
vesting and (except in the case of retirement plans) benefit accrual under such
employee benefit plans, the service of the employees of the SFC companies prior
to the Effective Time shall be treated as service with a UPC company
participating in such employee benefit plans. UPC will assume, in accordance
with their terms, and UPC shall, and shall cause SFC to, abide by all
employment, severance, consulting, and other compensation contracts disclosed to
UPC between any SFC company and any current or former director, officer or
employee thereof. In addition, UPC has agreed to transfer certain club
memberships currently held by 1(st) Savings Bank into personal status.
 
     SFC and the SFC subsidiaries maintain an ESOP for the benefit of eligible
employees. Under the ESOP, 64,475 shares of SFC Common Stock have been allocated
to participant accounts and 99,515 SFC shares are unallocated and held in a
suspense account. The unallocated shares secure a loan made to the ESOP to
acquire shares of SFC Common Stock. Pursuant to the Agreement, SFC subsidiaries
will, to the extent permitted by applicable law, maximize the employer
contributions to the ESOP, thereby causing an allocation of the shares held in
the suspense account of the ESOP participants and reducing the outstanding ESOP
loan balance, prior to the Effective Time. To the extent that SFC or the SFC
subsidiaries are unable to make contributions sufficient to fully repay the loan
prior to the Effective Time, at the Effective Time or as soon thereafter as
practicable, and contingent upon the issuance by the Internal Revenue Service of
a favorable determination letter, private letter ruling, or other authority
reasonably acceptable to UPC, it is intended that each of the following shall
occur: (a) shares of UPC Common Stock received by the ESOP in the Merger shall
be liquidated for cash in an amount sufficient to fully retire the then
outstanding balance of the ESOP loan including any accrued but unpaid interest
thereon, (b) all remaining unallocated shares shall be allocated to the accounts
of participants as earnings as of the Effective Time in accordance with
applicable Law, and (c) the ESOP shall make a distribution of benefits in a
manner consistent with applicable Law. The ESOP will be amended prior to the
Effective Time to delete the requirement that a participant must be employed on
the last day of the plan year in order to receive a contribution and to make
such other amendments as are appropriate to maximize the benefits to be realized
under the ESOP by participants including a provision that, except as otherwise
provided herein, the ESOP shall be terminated at the Effective Time with all
participant accounts becoming fully vested and nonforfeitable.
 
     INDEMNIFICATION.  The Agreement provides that UPC will indemnify, defend
and hold harmless the present and former directors, officers, employees, and
agents of the SFC companies against all liabilities arising out of actions or
omissions occurring at or prior to the Effective Time (including the
transactions contemplated by the Agreement and the Option Agreement) to the full
extent permitted under Delaware law and by SFC's Certificate or Bylaws. In any
case in which approval by UPC is required to effectuate any indemnification, UPC
shall direct, at the election of the indemnified party, the determination of any
such approval will be made by independent counsel mutually agreed upon between
UPC and the indemnified party.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     THE FOLLOWING IS A SUMMARY OF THE MATERIAL ANTICIPATED FEDERAL INCOME TAX
CONSEQUENCES OF THE MERGER TO SFC STOCKHOLDERS. THIS SUMMARY IS BASED ON THE
FEDERAL INCOME TAX LAWS AS NOW IN EFFECT AND AS CURRENTLY INTERPRETED; IT DOES
NOT TAKE INTO ACCOUNT POSSIBLE CHANGES IN SUCH LAWS OR INTERPRETATIONS,
INCLUDING AMENDMENTS TO APPLICABLE STATUTES OR REGULATIONS OR CHANGES IN
JUDICIAL OR ADMINISTRATIVE RULINGS, SOME OF WHICH MAY HAVE RETROACTIVE EFFECT.
THIS SUMMARY DOES NOT PURPORT TO ADDRESS ALL ASPECTS OF THE POSSIBLE FEDERAL
INCOME TAX CONSEQUENCES OF THE MERGER AND IS NOT INTENDED AS TAX ADVICE TO ANY
PERSON. IN PARTICULAR, AND WITHOUT LIMITING THE FOREGOING, THIS SUMMARY DOES NOT
ADDRESS THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO SFC STOCKHOLDERS IN
LIGHT OF THEIR PARTICULAR CIRCUMSTANCES OR STATUS (FOR EXAMPLE, AS FOREIGN
PERSONS, TAX-EXEMPT ENTITIES, DEALERS IN SECURITIES, INSURANCE COMPANIES, AND
CORPORATIONS, AMONG OTHERS). NOR DOES THIS SUMMARY ADDRESS ANY CONSEQUENCES OF
THE MERGER UNDER ANY STATE, LOCAL, ESTATE, OR FOREIGN TAX LAWS. SFC
STOCKHOLDERS, THEREFORE, ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING TAX RETURN REPORTING
REQUIREMENTS, THE APPLICATION AND EFFECT OF FEDERAL, FOREIGN, STATE, LOCAL, AND
OTHER TAX LAWS, AND THE IMPLICATIONS OF ANY PROPOSED CHANGES IN THE TAX LAWS.
 
     A federal income tax ruling with respect to this transaction has not been,
and will not be, requested from the Internal Revenue Service ("IRS"). Instead,
Alston & Bird LLP, counsel to UPC, has rendered an opinion ("Tax Opinion") to
SFC and UPC concerning certain federal income tax consequences of the proposed
Merger under federal income tax law. It is such firm's opinion that, based upon
the assumption that the Merger is consummated in accordance with Delaware law
and the Agreement and in conformity with certain factual representations made by
the managements of SFC and UPC, the transaction will have the following federal
income tax consequences:
 
          (a) The Merger followed by the Second Merger will qualify as a
     reorganization within the meaning of Section 368(a) of the Code.
 
          (b) No gain or loss will be recognized by SFC upon the receipt of the
     assets of UPC Merger Subsidiary in exchange solely for SFC Common Stock and
     the assumption by SFC of the liabilities of UPC Merger Subsidiary.
 
          (c) No gain or loss will be recognized by UPC or UPC Merger Subsidiary
     on receipt by UPC of SFC Common Stock and the assumption by SFC of the
     liabilities of UPC Merger Subsidiary solely in exchange for the assets of
     UPC Merger Subsidiary.
 
          (d) The basis of UPC Merger Subsidiary's assets in the hands of SFC
     will, in each case, be the same as the basis of those assets in the hands
     of UPC Merger Subsidiary immediately prior to the transaction.
 
          (e) The holding period of the assets of UPC Merger Subsidiary in the
     hands of SFC will, in each case, include the period during which such
     assets were held by UPC Merger Subsidiary.
 
          (f) No gain or loss will be recognized by a SFC stockholder upon the
     receipt of UPC Common Stock (including any associated UPC Rights) solely in
     exchange for its shares of SPC Common Stock.
 
          (g) The basis of the UPC Common Stock received by a SFC stockholder in
     the transaction will, in each instance, be the same as the basis of the SFC
     Common Stock surrendered in exchange therefor less the basis allocated to
     any fractional share of UPC Common Stock settled by cash payment.
 
          (h) The holding period of the UPC Common Stock received by a SFC
     stockholder (including the holding period of any fractional share interest)
     will include the holding period of the SFC Common Stock surrendered in
     exchange therefor, provided the SFC Common Stock was held as a capital
     asset on the date of the exchange.
 
          (i) The payment of cash in lieu of fractional shares of UPC Common
     Stock will be treated as if the fractional shares were issued as part of
     the exchange and then redeemed by UPC. These cash payments will be treated
     as having been received as distributions in full payment in exchange for
     the fractional
 
                                       32
<PAGE>   41
 
     shares of UPC Common Stock redeemed as provided in Section 302(a).
     Generally, any gain or loss recognized upon such exchange will be capital
     gain or loss, provided the fractional share would constitute a capital
     asset in the hands of the exchanging stockholder.
 
     The Tax Opinion does not address any state, local, or other tax
consequences of the Merger. The Tax Opinion does not bind the IRS nor preclude
the IRS from adopting a contrary position. In addition, the Tax Opinion will be
subject to certain assumptions and qualifications and will be based on the truth
and accuracy of certain representations made by the management of SFC and UPC,
as to, among other things, the fact that there is no plan or intention by any of
the stockholders of SFC who own 5% or more of the outstanding SFC Common Stock,
and to the best of the knowledge of the management of SFC, the remaining SFC
stockholders have no plan or intention, to sell, exchange, or otherwise dispose
of a number of shares of UPC Common Stock that they will receive in the Merger
that will reduce on the part of the SFC stockholders such stockholders'
ownership of UPC Common Stock to a number of shares having an aggregate value as
of the date of the Merger of less than 50% of the aggregate value of all of the
stock of SFC outstanding immediately prior to the Merger.
 
     A successful IRS challenge to the "reorganization" status of the Merger
would result in a SFC stockholder recognizing gain or loss with respect to each
share of SFC Common Stock surrendered equal to the difference between the
stockholder's adjusted tax basis in such share and the fair market value, as of
the Effective Time of the Merger, of the UPC Common Stock received in exchange
therefor. In such event, a SFC stockholder's aggregate basis in the UPC Common
Stock received would equal its fair market value and his or her holding period
for such UPC Common Stock would begin the day after the Merger.
 
ACCOUNTING TREATMENT
 
     It is anticipated that the Merger will be accounted for as a "purchase," as
that term is used pursuant to generally accepted accounting principles, for
accounting and financial reporting purposes. Under the purchase method of
accounting, the assets and liabilities of SFC as of the Effective Date will be
recorded at their estimated respective fair values and added to those of UPC.
Financial statements of UPC issued after the Effective Date will reflect such
values and will not be restated retroactively to reflect the historical
financial position or results of operations of SFC.
 
EXPENSES AND FEES
 
     The Agreement provides that each of the parties will bear and pay its own
expenses in connection with the transactions contemplated by the Agreement,
including fees and expenses of its own financial or other consultants,
investment bankers, accountants, and counsel, except that UPC will bear and pay
the filing fees payable in connection with the Registration Statement and this
Proxy Statement and the printing costs and certain other third-party costs in
connection with the Registration Statement and this Proxy Statement.
 
RESALES OF UPC COMMON STOCK
 
     UPC Common Stock to be issued to stockholders of SFC in connection with the
Merger will be registered under the Securities Act. All shares of UPC Common
Stock received by holders of SFC Common Stock and all shares of UPC Common Stock
issued and outstanding immediately prior to the Effective Time, will be freely
transferable upon consummation of the Merger by those stockholders of SFC not
deemed to be "Affiliates" of SFC or UPC. "Affiliates" generally are defined as
persons or entities who control, are controlled by, or are under common control
with SFC or UPC at the time of the Special Meeting (generally, executive
officers, directors and 10% stockholders).
 
     Rule 145 promulgated under the Securities Act restricts the sale of UPC
Common Stock received in the Merger by Affiliates and certain of their family
members and related interests. Under the Rule, during the one year following the
Effective Time, Affiliates of SFC or UPC may resell publicly the UPC Common
Stock received by them in the Merger within certain limitations as to the amount
of UPC Common Stock sold in any three-month period and as to the manner of sale.
After the one-year period, such Affiliates of SFC who are not Affiliates of UPC
may resell their shares without restriction. The ability of Affiliates to resell
shares of
 
                                       33
<PAGE>   42
 
UPC Common Stock received in the Merger under Rule 145 will be subject to UPC
having satisfied its Exchange Act reporting requirements for specified periods
prior to the time of sale. Affiliates will receive additional information
regarding the effect of Rule 145 on their ability to resell UPC Common Stock
received in the Merger. Affiliates also would be permitted to resell UPC Common
Stock received in the Merger pursuant to an effective registration statement
under the Securities Act or an available exemption from the Securities Act
registration requirements. This Proxy Statement does not cover any resales of
UPC Common Stock received by persons who may be deemed to be Affiliates of SFC
or UPC.
 
     SFC has agreed to use its reasonable efforts to cause each person who may
be deemed to be an Affiliate of SFC to execute and deliver to UPC not later than
30 days prior to the Effective Time, an agreement (each, an "Affiliate
Agreement") providing that such Affiliate will not sell, pledge, transfer, or
otherwise dispose of any SFC Common Stock held by such Affiliate except as
contemplated by the Agreement or the Affiliate Agreement, and will not sell,
pledge, transfer or otherwise dispose of any UPC Common Stock received by such
Affiliate upon consummation of the Merger, except in compliance with the
Securities Act and the rules and regulations thereunder. See "--  Conditions to
Consummation of the Merger."
 
OPTION AGREEMENT
 
     As an inducement and a condition to UPC entering into the Agreement, SFC
and UPC entered into the Option Agreement, pursuant to which SFC granted UPC an
option (the "Option") entitling it to purchase up to 298,228 shares
(representing 19.9% of the shares issued and outstanding before giving effect to
the exercise of such option) of SFC Common Stock under the circumstances
described below, at a cash price per share equal to $37.00, subject to possible
adjustment in certain circumstances (the "Purchase Price"). This description of
the Option Agreement and the Option does not purport to be complete and is
qualified in its entirety by reference to the Option Agreement, which is filed
as an exhibit to this Registration Statement and incorporated herein by
reference.
 
     Notwithstanding anything to the contrary contained in the Option Agreement,
in no event may the Total Profit (as defined below) of UPC exceed $3.0 million
and, if it otherwise would exceed such amount, UPC, at its sole election, must
either (a) reduce the number of shares of SFC Common Stock subject to the
Option, (b) deliver to SFC for cancellation the shares of SFC Common Stock
previously purchased pursuant to the Option, (c) pay cash to SFC or any
combination thereof, so that UPC will not actually realize Total Profit in
excess of $3.0 million after taking into account the foregoing actions. In
addition, the Option may not be exercised for a number of shares as would, as of
the date of exercise, result in a Notional Total Profit (as defined below) of
more than $3.0 million; provided, however, that this limitation will not
restrict any exercise of the Option permitted by the Option Agreement on any
subsequent date.
 
     "Total Profit" means the aggregate amount (before taxes) of the following:
(a) the amount received by UPC pursuant to SFC's repurchase of the Option (or
any portion thereof), (b)(i) the amount received by UPC pursuant to SFC's
repurchase of shares of SFC Common Stock purchased pursuant to the Option, less
(ii) the purchase price for such shares, (c)(i) the net cash amounts received by
UPC pursuant to the sale of SFC Common Stock purchased pursuant to the Option
(or any other securities into which such shares may be converted or exchanged)
to any unaffiliated party, less (ii) the purchase price of such shares, and (d)
any amounts received by UPC on the transfer of the Option (or any portion
thereof) to any unaffiliated party.
 
     "Notional Total Profit" means the Total Profit determined as of the date of
such proposed exercise assuming that the Option were exercised on such date for
such number of shares and assuming that such shares, together with all other SFC
Common Stock purchased pursuant to the Option held by UPC and its affiliates as
of such date, were sold for cash at the closing sale price per share of SFC
Common Stock as quoted on the Nasdaq/NMS as of the close of business on the
preceding trading day (less customary brokerage commissions).
 
     Subject to applicable law and regulatory restrictions, UPC may exercise the
Option, in whole or in part, if, but only if, a Purchase Event (as defined
below) occurs prior to the Option's termination; provided that UPC, at the time,
is not in material breach of the Option Agreement or the Agreement. As defined
in the Option Agreement, "Purchase Event" means either of the following events:
 
                                       34
<PAGE>   43
 
          (a) without UPC's written consent, SFC authorizing, recommending,
     publicly proposing, or publicly announcing an intention to authorize,
     recommend, or propose or entering into an agreement with any third party to
     effect (i) a merger, consolidation, or similar transaction involving SFC or
     any of its subsidiaries (other than transactions solely between SFC's
     subsidiaries), (ii) except as permitted by the Agreement, the disposition,
     by sale, lease, exchange, or otherwise, of 25% or more of the consolidated
     assets of SFC and its subsidiaries or (iii) the issuance, sale, or other
     disposition (including by way of merger, consolidation, share exchange or
     any similar transaction) of securities representing 25% or more of the
     voting power of SFC or any of its subsidiaries; or
 
          (b) any third party acquiring beneficial ownership, or the right to
     acquire beneficial ownership of, or the formation of any group (as defined
     under the Exchange Act) that beneficially owns or has the right to acquire
     beneficial ownership of, 25% or more of the outstanding shares of SFC
     Common Stock.
 
     The Option will terminate upon the earliest of the following:
 
          (a) the Effective Time;
 
          (b) termination of the Agreement in accordance with the terms thereof
     prior to the occurrence of a Purchase Event or a Preliminary Purchase Event
     (other than a termination of the Agreement under certain circumstances
     involving a willful breach by SFC) (a "Default Termination");
 
          (c) 12 months after termination of the Agreement by UPC pursuant to a
     Default Termination; and
 
          (d) 12 months after termination of the Agreement (other than pursuant
     to a Default Termination) following the occurrence of a Purchase Event or a
     Preliminary Purchase Event.
 
     As defined in the Option Agreement, "Preliminary Purchase Event" includes
either of the following events:
 
          (a) commencement or filing of a registration statement under the
     Securities Act by any third party of a tender offer or exchange offer to
     purchase any shares of SFC Common Stock such that, upon consummation of
     such offer, such person would own or control 25% or more of the
     then-outstanding shares of SFC Common Stock (a "Tender Offer" or an
     "Exchange Offer," respectively); or
 
          (b) failure of the stockholders of SFC to approve the Agreement and
     the Plan of Merger at the meeting of such stockholders held for the purpose
     of voting on the Agreement, the failure to have such meeting or the
     cancellation thereof prior to termination of the Agreement, or the
     withdrawal or modification by SFC's Board of Directors in a manner adverse
     to UPC of the recommendation of the Board of Directors with respect to the
     Agreement, in each case, after public announcement that a third party (i)
     made a proposal to engage in an acquisition transaction, (ii) commenced a
     Tender Offer or filed a registration statement under the Securities Act
     with respect to an Exchange Offer or (iii) filed an application or given a
     notice under certain federal statutes for approval or consent to engage in
     an acquisition transaction.
 
     In the event of any change in SFC Common Stock by reason of a stock
dividend, stock split, split-up, recapitalization, combination, exchange of
shares, or similar transaction, the type and number of securities subject to the
Option, and the purchase price therefor shall be adjusted appropriately. In the
event that any additional shares of SFC Common Stock are issued after June 23,
1997 (other than pursuant to an event described in the preceding sentence), the
number of shares of SFC Common Stock subject to the Option will be adjusted so
that, after such issuance, it, together with any shares of SFC Common Stock
previously issued pursuant to the Option Agreement, equals 19.9% of the number
of shares then issued and outstanding, without giving effect to any shares
subject to or issued pursuant to the Option.
 
     Upon the occurrence of a Repurchase Event (as defined below) that occurs
prior to the exercise or termination of the Option, at the request of UPC,
delivered within 12 months of the Repurchase Event, SFC will, subject to
regulatory restrictions, be obligated to repurchase the Option and any shares of
SFC Common Stock therefor purchased pursuant to the Option Agreement at a
specified price.
 
                                       35
<PAGE>   44
 
     As defined in the Option Agreement, "Repurchase Event" shall occur if (i)
any person (other than UPC or any UPC subsidiary) shall have acquired actual
ownership or control, or any "group" (as such term is defined under the Exchange
Act) shall have been formed which has acquired actual ownership or control of
50% or more of the then-outstanding shares of SFC Common Stock, or (ii) any of
the following transactions is consummated: (a) SFC consolidates with or merges
into any person, other than UPC or one of UPC's subsidiaries, and is not the
continuing or surviving corporation of such consolidation or merger; (b) SFC
permits any person, other than UPC or one of UPC's subsidiaries, to merge into
SFC and SFC shall be the continuing or surviving corporation, but, in connection
with such merger, the then-outstanding shares of SFC Common Stock shall be
changed into or exchanged for stock or other securities of SFC or any other
person or cash or any other property or the outstanding shares of SFC Common
Stock immediately prior to such merger shall after such merger represent less
than 50% of the outstanding shares and share equivalents of the merged company;
or (c) SFC sells or otherwise transfers all or substantially all of its assets
to any person, other than UPC or one of UPC's subsidiaries.
 
     In the event that prior to the exercise or termination of the Option, SFC
enters into an agreement to engage in any of the transactions described in
clause (ii) of the definition of Repurchase Event above, the agreement governing
such transaction must make proper provision so that UPC will receive for each
share of SFC Common Stock subject to the option an amount of consideration that
would be received by a holder of SFC Common Stock in such transaction less the
Purchase Price.
 
     After the occurrence of a Purchase Event, UPC may assign the Option
Agreement and its rights thereunder in whole or in part.
 
     Upon the occurrence of certain events, SFC has agreed to file with the SEC
and to cause to become effective certain registration statements under the
Securities Act with respect to dispositions by UPC and its assigns of all or
part of the Option and/or any shares of SFC Common Stock into which the Option
is exercisable.
 
                 EFFECT OF THE MERGER ON RIGHTS OF STOCKHOLDERS
 
     As a result of the Merger, holders of SFC Common Stock will be exchanging
their shares of a Delaware corporation governed by the DGCL and SFC's
Certificate and Bylaws, for shares of UPC, a Tennessee corporation governed by
the TBCA and UPC's Charter of Incorporation, as amended (the "Charter"), and
Bylaws. Certain significant differences exist between the rights of SFC
stockholders and those of UPC stockholders. In particular, UPC's Charter and
Bylaws contain several provisions that may be deemed to have an anti-takeover
effect in that they could impede or prevent an acquisition of UPC unless the
potential acquirer has obtained the approval of UPC's Board of Directors. The
following discussion is necessarily general; it is not intended to be a complete
statement of all differences affecting the rights of stockholders and their
respective entities, and it is qualified in its entirety by reference to the
DGCL and the TBCA as well as to UPC's Charter and Bylaws and SFC's Certificate
and Bylaws.
 
ANTI-TAKEOVER PROVISIONS GENERALLY
 
     The provisions of UPC's Charter and Bylaws described below under the
headings, " -- Authorized Capital Stock," " -- Amendment of Charter and Bylaws,"
" -- Classified Board of Directors and Absence of Cumulative Voting,"
" -- Director Removal and Vacancies," " -- Limitations on Director Liability,"
" -- Indemnification, " -- Special Meeting of Stockholders," " -- Actions by
Stockholders Without a Meeting," " -- Stockholder Nominations and Proposals" and
" -- Business Combinations" are referred to herein as the "Protective
Provisions." In general, one purpose of the Protective Provisions is to assist
UPC's Board of Directors in playing a role if any group or person attempts to
acquire control of UPC, so that the Board of Directors of UPC can further
protect the interests of UPC and its stockholders as appropriate under the
circumstances, including, if the Board of Directors of UPC determines that a
sale of control is in their best interests, by enhancing the Board of Directors
of UPC's ability to maximize the value to be received by the stockholders upon
such a sale.
 
                                       36
<PAGE>   45
 
     Although UPC's management believes the Protective Provisions are,
therefore, beneficial to UPC's stockholders, the Protective Provisions also may
tend to discourage some takeover bids. As a result, UPC's stockholders may be
deprived of opportunities to sell some or all of their shares at prices that
represent a premium over prevailing market prices. On the other hand, defeating
undesirable acquisition offers can be a very expensive and time-consuming
process. To the extent that the Protective Provisions discourage undesirable
proposals, UPC may be able to avoid those expenditures of time and money.
 
     The Protective Provisions also may discourage open market purchases by a
potential acquirer. Such purchases may increase the market price of UPC Common
Stock temporarily, enabling stockholders to sell their shares at a price higher
than that which otherwise would prevail. In addition, the Protective Provisions
may decrease the market price of UPC Common Stock by making the stock less
attractive to persons who invest in securities in anticipation of price
increases from potential acquisition attempts. The Protective Provisions also
may make it more difficult and time consuming for a potential acquirer to obtain
control of UPC through replacing the Board of Directors and management.
Furthermore, the Protective Provisions may make it more difficult for UPC's
stockholders to replace the Board of Directors or management, even if a majority
of the stockholders believe such replacement is in the best interests of UPC. As
a result, the Protective Provisions may tend to perpetuate the incumbent Board
of Directors and management.
 
AUTHORIZED CAPITAL STOCK
 
     UPC.  UPC's Charter authorizes the issuance of up to (i) 100,000,000 shares
of UPC Common Stock, of which 66,928,481 shares were issued and outstanding as
of July 31, 1997, and (ii) 10,000,000 shares of no par value preferred stock
("UPC Preferred Stock"), of which no shares of UPC Series A Preferred Stock, and
2,412,578 shares of UPC Series E Preferred Stock were issued and outstanding as
of July 31, 1997. UPC's Board of Directors may authorize the issuance of
additional shares of UPC Common Stock without further action by UPC's
stockholders, unless such action is required in a particular case by applicable
laws or regulations or by any stock exchange upon which UPC's capital stock may
be listed.
 
     Similarly, with certain exceptions, UPC's Board of Directors may issue,
without any further action by the stockholders, shares of UPC Preferred Stock,
in one or more classes or series, with such voting, conversion, dividend, and
liquidation rights as specified in UPC's Charter. In providing for the issuance
of such shares, UPC's Board of Directors may determine, among other things, the
distinctive designation and number of shares comprising a series of preferred
stock, the dividend rate or rates on the shares of such series and the relation
of such dividends to the dividends payable on other classes of stock, whether
the shares of such series shall be convertible into or exchangeable for shares
of any other class or series of UPC capital stock, the voting powers if any of
such series, and any other preferences, privileges, and powers of such series.
 
     In the event of the voluntary or involuntary liquidation, dissolution,
distribution of assets or winding up of UPC, the holders of any series of UPC
Preferred Stock will have priority over holders of UPC Common Stock.
 
     The authority to issue additional shares of UPC Common Stock or Preferred
Stock provides UPC with the flexibility necessary to meet its future needs
without the delay resulting from seeking stockholder approval. The authorized
but unissued shares of UPC Common Stock and UPC Preferred Stock will be issuable
from time to time for any corporate purpose, including, without limitation,
stock splits, stock dividends, employee benefit and compensation plans,
acquisitions, and public or private sales for cash as a means of raising
capital. Such shares could be used to dilute the stock ownership of persons
seeking to obtain control of UPC. In addition, the sale of a substantial number
of shares of UPC voting stock to persons who have an understanding with UPC
concerning the voting of such shares, or the distribution or declaration of a
dividend of shares of UPC voting stock (or the right to receive UPC voting
stock) to UPC stockholders, may have the effect of discouraging or increasing
the cost of unsolicited attempts to acquire control of UPC.
 
     In 1989, the UPC Board of Directors adopted a Share Purchase Rights Plan
("Preferred Share Rights Plan") and distributed a dividend of one Preferred
Share Unit Purchase Right ("Preferred Share Right") for each outstanding share
of UPC Common Stock. In addition, under the Preferred Share Rights Plan, one
Preferred Share Right is to be automatically, and without further action by UPC,
distributed in respect to each
 
                                       37
<PAGE>   46
 
share of UPC Common Stock issued after adoption of the Preferred Share Rights
Plan. The Preferred Share Rights are generally designed to deter coercive
takeover tactics and to encourage all persons interested in potentially
acquiring control of UPC to treat each stockholder on a fair and equal basis.
Each Preferred Share Right trades in tandem with the share of UPC Common Stock
to which it relates until the occurrence of certain events indicating a
potential change in control of UPC. Upon the occurrence of such an event, the
Preferred Share Rights would separate from UPC Common Stock and each holder of a
Preferred Share Right (other than the potential acquiror) would be entitled to
purchase certain equity securities of UPC at prices below their market value.
UPC has authorized 750,000 shares of Series A Preferred Stock for issuance under
the Preferred Share Rights Plan and no shares have been issued as of the date of
this Proxy Statement. Until a Preferred Share Right is exercised, the holder
thereof, as such, has no rights of a stockholder of UPC, including the right to
vote or receive dividends.
 
     SFC.  SFC's Certificate authorizes the issuance of up to (i) 5,000,000
shares of SFC Common Stock, of which 1,498,636 shares were issued and
outstanding as of the SFC Record Date, and (ii) 1,000,000 shares of $.01 par
value preferred stock ("SFC Preferred Stock"), of which no shares had been
issued as of the SFC Record Date. SFC's Board of Directors may authorize the
issuance of additional authorized shares of SFC Common Stock without further
action by SFC's stockholders, unless such action is required in a particular
case by applicable laws or regulations or by any stock exchange upon which SFC's
capital stock may be listed.
 
     Subject to certain provisions of the DGCL, SFC's Board of Directors may
provide the issuance of the shares of SFC Preferred Stock and series, and by
filing a certificate pursuant to the applicable law of the State of Delaware (a
"Preferred Stock Designation"), to establish, from time to time, the number of
shares to be included in such series, and to fix the designation, powers,
preferences and rights of the shares of each such series and any qualifications,
limitations or restrictions. The number of authorized shares of SFC Preferred
Stock may be increased or decreased, though not below the level of the number of
shares then outstanding, by the affirmative vote of the holders of a majority of
SFC Common Stock, without a vote of the holders of SFC Preferred Stock, unless
required by a Preferred Stock Designation.
 
AMENDMENT OF CHARTER AND BYLAWS
 
     UPC.  The Charter of UPC provides that amendments thereto may be adopted in
any manner permitted by the TBCA. The TBCA provides that a corporation's charter
may be amended by a majority of votes entitled to be cast on the amendment,
subject to any condition the board of directors may place on its submission of
the amendment to the stockholders. The Charter requires a vote of two-thirds or
more of the shares of capital stock entitled to vote in an election of directors
to amend the articles of the Charter governing directors and to remove a
director from office whether with or without cause. A two-thirds vote is also
required to amend, alter or repeal the article of the Charter relating to
business combinations.
 
     The Board of Directors may adopt, amend, or repeal the Bylaws by a majority
vote of the entire Board of Directors. The Bylaws may also be amended or
repealed by action of UPC's stockholders.
 
     UPC's Charter provides that all corporate powers of UPC shall be exercised
by the Board of Directors except as otherwise provided by law. The Board of
Directors may designate an executive committee consisting of five or more
directors and may authorize such committee to exercise all of the authority of
the Board of Directors, including the authority to adopt, amend and repeal the
Bylaws, to submit any action to the stockholders, to fill vacancies on the Board
of Directors or any committee, to declare dividends or other corporate
distributions, and to issue or reissue any capital stock or any warrant, right
or option to acquire capital stock of the corporation.
 
     SFC.  The Certificate of SFC provides that SFC reserves the right to amend
or appeal any provision contained in the Certificate in the manner prescribed by
the laws of the State of Delaware and that all rights conferred upon the
stockholders are granted subject to such reservation; provided, that amendment
or repeal of the articles of the Certificate relating to amendment of the
Certificate, voting rights of controlling stockholders, action taken without
written consent, the calling of special meetings, the number of directors and
the method of replacing directors, amendment of the Bylaws of SFC, certain
business combinations, limitations on payment of "greenmail," indemnification,
and director liability requires the affirmative vote of
 
                                       38
<PAGE>   47
 
holders of at least 75% of the voting power of all the then-outstanding shares
of the capital stock of SFC entitled to vote generally in election of directors.
 
     SFC's Certificate provides that the Board of Directors has the power to
adopt, amend, or repeal the Bylaws of SFC. Any adoption, amendment, or repeal of
the Bylaws of SFC by the Board of Directors must be approved by a majority of
the Board of Directors. SFC's Certificate also provides that the stockholders
have the power to adopt, amend or appeal the Bylaws of SFC by the affirmative
vote of the holders of at least 75% of the voting power of all of the
then-outstanding shares of the capital stock of SFC entitled to vote generally
in the election of directors, voting together as a single class.
 
CLASSIFIED BOARD OF DIRECTORS AND ABSENCE OF CUMULATIVE VOTING
 
     UPC.  The Charter of UPC provides that UPC's Board of Directors is divided
into three classes, with each class to be as nearly equal in number as possible.
The directors in each class serve three-year terms of office. The effect of
UPC's having a classified Board of Directors is that only approximately
one-third of the members of the Board are elected each year, which effectively
requires two annual meetings for UPC's stockholders to change a majority of the
members of the Board. The purpose of dividing UPC's Board of Directors into
classes is to facilitate continuity and stability of leadership of UPC by
ensuring that experienced personnel familiar with UPC will be represented on
UPC's Board of Directors at all times, and to permit UPC's management to plan
for the future for a reasonable time. However, by potentially delaying the time
within which an acquirer could obtain working control of the Board, this
provision may discourage some potential mergers, tender offers, or takeover
attempts.
 
     Pursuant to the Charter of UPC, each stockholder is entitled to one vote
for each share of UPC Common Stock held and is not entitled to cumulative voting
rights in the election of directors. With cumulative voting, a stockholder has
the right to cast a number of votes equal to the total number of such holder's
shares multiplied by the number of directors to be elected. The stockholder has
the right to distribute all of his votes in any manner among any number of
candidates or to accumulate such shares in favor of one candidate. Directors are
elected by a plurality of the total votes cast by all stockholders. With
cumulative voting, it may be possible for minority stockholders to obtain
representation on the Board of Directors. Without cumulative voting, the holders
of more than 50% of the shares of UPC Common Stock generally have the ability to
elect 100% of the directors. As a result, the holders of the remaining UPC
Common Stock effectively may not be able to elect any person to the Board of
Directors. The absence of cumulative voting thus could make it more difficult
for a stockholder who acquires less than a majority of the shares of UPC Common
Stock to obtain representation on UPC's Board of Directors.
 
     SFC.  As permitted by the DGCL, SFC's Certificate contains a provision
similar to the provision in the Bylaws of UPC that requires that the Board of
Directors shall be divided into three classes serving staggered three-year
terms, with the term of one class of directors to expire each year. Pursuant to
the Bylaws of SFC, each stockholder is entitled to one vote for each share of
SFC Common Stock held and is not entitled to cumulative voting rights in the
election of directors.
 
DIRECTOR REMOVAL AND VACANCIES
 
     UPC.  UPC's Charter provides that a director may be removed by the
stockholders only upon the affirmative vote of the holders of two-thirds of the
voting power of all shares of capital stock entitled to vote generally in the
election of directors. The purpose of this provision is to prevent a majority
stockholder from circumventing the classified board system by removing directors
and filling the vacancies with new individuals selected by that stockholder.
Accordingly, the provision may have the effect of impeding efforts to gain
control of the Board of Directors by anyone who obtains a controlling interest
in UPC Common Stock. Vacancies on the board of directors may be filled by the
board of directors or stockholders, as provided under the UPC Bylaws and the
TBCA. The term of a director appointed to fill a vacancy expires at the next
meeting of stockholders at which directors are elected.
 
     SFC.  The DGCL provides that, unless the corporation's certificate of
incorporation provides otherwise, the stockholders of a corporation that has a
classified board (as described above) may remove a director only
 
                                       39
<PAGE>   48
 
for cause. In addition, the DGCL provides that, unless the corporation's
certificate of incorporation provides for a higher voting requirement, directors
may be removed by the holders of a majority of the shares then entitled to vote
in the election of such directors. SFC's Certificate and Bylaws provide that
directors may be removed only for cause and only by the affirmative vote of at
least 75% of the voting power of all the then-outstanding shares of capital
stock of SFC entitled to vote generally in the election of directors, voting
together as a single class.
 
LIMITATIONS ON DIRECTOR LIABILITY
 
     UPC.  UPC's Charter does not address the issue of director liability to the
corporation.
 
     SFC.  SFC's Certificate contains a provision limiting directors' liability
to the corporation or its stockholders. Under SFC's Certificate, as allowed by
Section 102 of the DGCL, a SFC director will not have personal liability to SFC
or its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability (i) for any breach of the director's duty of
loyalty to SFC or its stockholders, (ii) for acts or omissions not in good faith
or that involve intentional misconduct or a knowing violation of law, (iii) for
any act or omission under Section 174 of the DGCL (involving certain unlawful
dividends and stock purchases or redemptions) or (iv) for any transaction from
which the director derived an improper personal benefit. This provision would
absolve directors of personal liability for negligence in the performance of
duties, even gross negligence. It would not permit, however, a director to be
exculpated for liability for actions involving conflicts of interest or breaches
of the traditional duty of loyalty to SFC and its stockholders, and it would not
affect the availability of injunctive or other equitable relief to SFC or its
stockholders.
 
INDEMNIFICATION
 
     UPC.  Under the TBCA, subject to certain exceptions, a corporation may
indemnify an individual made a party to a proceeding, because he is or was a
director, against liability incurred in the proceeding if (i) he conducted
himself in good faith; (ii) he reasonably believed (a) in the case of conduct in
his official capacity with the corporation, that his conduct was in the best
interests of the corporation, and (b) in all other cases, that his conduct was
at least not opposed to the corporation's best interests; and (iii) in the case
of any criminal proceeding, he had no reasonable cause to believe his conduct
was unlawful (the "Standard of Conduct"). Moreover, unless limited by its
articles of incorporation, a corporation must indemnify a director who was
wholly successful, on the merits or otherwise, in the defense of any proceeding
to which he was a party because he is or was a director of the corporation
against reasonable expenses incurred by him in connection with the proceeding.
Expenses incurred by a director in defending a proceeding may be paid by the
corporation in advance of the final disposition of such proceeding upon receipt
of a written affirmation by the director of his good faith belief that he or she
has met the Standard of Conduct and an undertaking by or on behalf of a director
to repay such amount unless it shall ultimately be determined that he is
entitled to be indemnified by the corporation against such expenses. Before any
such indemnification is made, it must be determined that such indemnification
would not be precluded by Part 5 of the TBCA.
 
     A director may also apply for court-ordered indemnification under certain
circumstances. Unless a corporation's articles of incorporation provide
otherwise, (i) an officer of a corporation is entitled to mandatory
indemnification and is entitled to apply for court-ordered indemnification to
the same extent as a director; (ii) the corporation may indemnify and advance
expenses to an officer, employee, or agent of the corporation to the same extent
as to a director; and (iii) a corporation may also indemnify and advance
expenses to an officer, employee, or agent who is not a director to the extent,
consistent with public policy, that may be provided by its articles of
incorporation, bylaws, general or specific action of its board of directors, or
contract.
 
     UPC's Charter and Bylaws provide for the indemnification of its directors
and officers, to the fullest extent permitted by Tennessee law.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers, or persons controlling UPC pursuant to
the foregoing provisions, UPC has been informed that, in the opinion of the SEC,
such indemnification is against public policy as expressed in the Securities Act
and is therefore unenforceable.
 
                                       40

     SFC.  SFC's Certificate provides that each person who is or is made a party
or is threatened to be made a party to, or is otherwise involved in any action,
suit or proceeding, whether civil, criminal, administrative or investigative,
because of the fact that he or she was a director or an officer of SFC or is or
was serving at the request of SFC as an officer or director of another
corporation, including, without limitation, any subsidiary, partnership, joint
venture, trust or other enterprise, including service with respect to an
employee benefit plan, whether the allegations are based on his or her action in
an official capacity as a director or officer, will be indemnified and held
harmless by SFC to the fullest extent authorized by the DGCL, against all
expense, liability and loss (including attorneys' fees, judgments, fines, ERISA
excise taxes or penalties in amounts paid in the settlement) reasonably incurred
or suffered; provided, that such indemnification shall only apply in connection
with proceedings initiated by the indemnitee if such proceeding was authorized
by the Board of Directors of SFC.
 
SPECIAL MEETING OF STOCKHOLDERS
 
     UPC.  UPC's Bylaws provide that special meetings of stockholders may be
called, unless otherwise prescribed by law, for any purpose or purposes whatever
at any time by the Chairman of the Board, the President, the Secretary, or the
holders of not less than one-tenth of the shares entitled to vote at such
meeting.
 
     SFC.  The DGCL provides that special meetings of stockholders may be called
by such persons as may be authorized by a corporation's certificate of
incorporation or bylaws. SFC's Bylaws provide that special meetings of
stockholders of SFC may be called only by the Board of Directors of SFC pursuant
to a resolution adopted by a majority of the total number of directors which SFC
would have if there were no vacancies on the Board of Directors. Because a
special meeting may be necessary for a potential acquirer to gain control of
SFC, this requirement could discourage or make more difficult an attempt to gain
control of SFC, and could tend to perpetuate the incumbent directors and
management.
 
ACTIONS BY STOCKHOLDERS WITHOUT A MEETING
 
     UPC.  The Charter and Bylaws of UPC provide that any action required or
permitted to be taken by UPC stockholders at a duly called meeting of
stockholders may be effected by the unanimous written consent of the
stockholders entitled to vote on such action.
 
     SFC.  The Certificate states that any action required or permitted to be
taken by the stockholders must be effected by a duly constituted meeting and may
not be effected by written consent.
 
STOCKHOLDER NOMINATIONS AND PROPOSALS
 
     UPC.  UPC's Charter and Bylaws do not address whether a stockholder may
nominate members of the Board of Directors.
 
     SFC.  SFC's Bylaws generally provide that any stockholder of the
corporation entitled to vote for the election of directors may nominate persons
for election to the Board of Directors. The stockholder must provide written
notice of such nomination to the Secretary of SFC at least 30 days prior to the
date of the meeting at which the election of directors is to be held. The
stockholder's notice must set forth all information relating to the person whom
the stockholder proposes to nominate that is required to be disclosed in
solicitations of proxies for election of directors, or is otherwise required,
under the Exchange Act.
 
     The SFC Bylaws also provide that any stockholder who is entitled to vote at
the annual meeting of stockholders may propose business to be conducted at such
meeting. The business must relate to a proper subject matter for stockholder
action, and the stockholder must provide written notice to the Secretary of SFC
at least 30 days prior to the date of the meeting at which the business is to be
conducted. The stockholder must set forth in the notice provided to the
Secretary, a brief description of the business the stockholder desires to
conduct, as well as any material interest of the stockholder in such business.

BUSINESS COMBINATIONS
 
     UPC.  The Charter of UPC requires the affirmative vote of the holders of
two-thirds of UPC's outstanding Common Stock for approval of a merger,
consolidation, or a sale or lease of all or substantially all of the assets of
UPC if the other party to the transaction is a beneficial owner of 10% or more
of the outstanding shares of UPC. A two-thirds vote is not required for any
merger or consolidation of UPC with or into any corporation or entity of which a
majority of the outstanding shares of all classes of capital stock entitled to
vote in the election of directors is owned by UPC or any UPC company.
 
     The requirement of a supermajority vote of stockholders to approve certain
business transactions, as described above, may discourage a change in control of
UPC by allowing a minority of UPC's stockholders to prevent a transaction
favored by the majority of the stockholders. Also, in some circumstances, the
Board of Directors could cause a two-thirds vote to be required to approve a
transaction thereby enabling management to retain control over the affairs of
UPC and their positions with UPC. The primary purpose of the supermajority vote
requirement, however, is to encourage negotiations with UPC's management by
groups or corporations interested in acquiring control of UPC and to reduce the
danger of a forced merger or sale of assets.
 
     As a Tennessee corporation, UPC is or could be subject to various
legislative acts set forth in Chapter 35 of Title 48 of the Tennessee Code,
which imposes certain restrictions on business combinations, including, but not
limited to, combinations with interested stockholders similar to those described
above.
 
     The Tennessee Business Combination Act generally prohibits a "business
combination" (generally defined to include mergers, share exchanges, sales and
leases of assets, issuances of securities, and similar transactions) by UPC or a
subsidiary with an "interested stockholder" (generally defined as any person or
entity which beneficially owns 10% or more of the voting power of any class or
series of UPC's stock then outstanding) within five years after the person or
entity becomes an interested stockholder, unless the business combination or the
transaction pursuant to which the interested stockholder became such was
approved by the UPC Board of Directors before the interested stockholder became
such, and the business combination satisfies any other applicable requirements
imposed by law or by UPC's Charter or Bylaws. The Tennessee Business Combination
Act also severely limits the extent to which UPC or any of its officers or
directors could be held liable for resisting any business combination.
 
     The Tennessee Control Share Acquisition Act (the "Tennessee CSAA")
generally provides that any person or group of persons that acquires the power
to vote more than specified levels (one-fifth, one-third or a majority) of the
shares of certain Tennessee corporations will not have the right to vote such
shares unless granted voting rights by the holders of a majority of the votes
entitled to be cast, excluding "interested shares." Interested shares are those
shares held by the acquiring person, officers of the corporation, and employees
of the corporation who are also directors of the corporation. If approval of
voting power for the shares is obtained at one of the specified levels,
additional stockholder approval is required when a stockholder seeks to acquire
the power to vote shares at the next level. In the absence of such approval, the
additional shares acquired by the stockholder may not be voted until they are
transferred to another person in a transaction other than a control share
acquisition. The Tennessee CSAA applies only to those Tennessee corporations
whose charters or bylaws contain an express declaration that control share
acquisitions in respect of the shares of such corporations are governed by and
subject to the provisions of such act. UPC's Charter and Bylaws do not currently
contain such an express declaration.
 
     The Tennessee Greenmail Act ("Tennessee GA") prohibits a Tennessee
corporation having a class of voting stock registered or traded on a national
securities exchange or registered with the SEC pursuant to Section 12(g) of the
Exchange Act from purchasing, directly or indirectly, any of its shares at a
price above the market value of such shares (defined as the average of the
highest and lowest closing market price of such shares during the 30 trading
days preceding the purchase or preceding the commencement or announcement of a
tender offer if the seller of such shares has commenced a tender offer or
announced an intention to seek control of the corporation) from any person who
holds more than 3% of the class of securities to be purchased if such person has
held such shares for less than two years, unless the purchase has been approved
by the
 
                                       42
<PAGE>   51
 
affirmative vote of a majority of the outstanding shares of each class of voting
stock issued by such corporation or the corporation makes an offer, of at least
equal value per share, to all holders of shares of such class.
 
     The TBCA provides that no Tennessee corporation having any class of voting
stock registered or traded on a national securities exchange or registered with
the SEC pursuant to Section 12(g) of the Exchange Act or any of its officers or
directors may be held liable at law or in equity for either having failed to
approve the acquisition of shares by an interested stockholder on or before the
date such stockholder became an interested stockholder, or for seeking to
enforce or implement the provisions of the Tennessee Business Combination Act or
the Tennessee CSAA, or for failing to adopt or recommend any charter or bylaw
amendment or provision in respect of any one or more of these acts or the
Tennessee GA, or for opposing any merger, exchange, tender offer or significant
disposition of the assets of the resident domestic corporation or any subsidiary
of such corporation because of a good faith belief that such merger, exchange,
tender offer or significant disposition of assets would adversely affect the
corporation's employees, customers, suppliers, the communities in which the
corporation or its subsidiaries operate or are located or any other relevant
factor if such factors are permitted to be considered by the board of directors
under the corporation's charter in connection with the merger, exchange, tender
offer or significant disposition of assets.
 
     The acts described above along with the provisions of UPC's Charter
regarding business combinations might be deemed to make UPC less attractive as a
candidate for acquisition by another company than would otherwise be the case in
the absence of such provisions. For example, if another company should seek to
acquire a controlling interest of less than 66-2/3% of the outstanding shares of
UPC Common Stock, the acquiror would not thereby obtain the ability to replace a
majority of the UPC Board of Directors until at least the second annual meeting
of stockholders following the acquisition, and furthermore the acquiror would
not obtain the ability immediately to effect a merger, consolidation, or other
similar business combination unless the described conditions were met.
 
     As a result, UPC's stockholders may be deprived of opportunities to sell
some or all of their shares at prices that represent a premium over prevailing
market prices in a takeover context. The provisions described above also may
make it more difficult for UPC's stockholders to replace the UPC Board of
Directors or management, even if the holders of a majority of the UPC Common
Stock should believe that such replacement is in the interests of UPC. As a
result, such provisions may tend to perpetuate the incumbent UPC Board of
Directors and management.
 
     SFC.  The DGCL requires the approval of the Board of Directors and the
holders of a majority of the outstanding stock of SFC entitled to vote thereon
for mergers or consolidations, and for sales, leases, or exchanges of
substantially all of SFC's property and assets. The DGCL permits SFC to merge
with another corporation without obtaining the approval of SFC's stockholders
if: (i) SFC is the surviving corporation of the merger; (ii) the merger
agreement does not amend SFC's Certificate; (iii) each share of SFC stock
outstanding immediately prior to the effective date of the merger is to be an
identical outstanding or treasury share of SFC after the merger; and (iv) any
authorized unissued shares or treasury shares of SFC Common Stock to be issued
or delivered under the plan of merger plus those initially issuable upon
conversion of any other securities or obligations to be issued or delivered
under such plan do not exceed 20% of the shares of SFC Common Stock outstanding
immediately prior to the effective date of the merger. As a result, SFC's Board
of Directors could effect significant acquisitions and issue significant amounts
of SFC capital stock on terms that may dilute the interests of existing SFC
stockholders, without seeking stockholder approval.
 
     Section 203 of the DGCL ("Section 203"). Section 203 generally prohibits
any person who acquires 15% or more of a corporation's outstanding voting stock
(an "Interested Stockholder") from entering into any "Business Combination" with
the corporation for three years, unless one of the specified exceptions applies.
"Business Combination" is defined generally to include mergers and
consolidations, dispositions of the corporation's assets, transactions resulting
in the issuance or transfer by the corporation of its stock, transactions having
the effect of increasing the proportionate share of the stock of any class or
series of the corporation, and the receipt by the Interested Stockholder of
certain financial benefits provided by or through the corporation.
 
                                       43
<PAGE>   52
 
     That three-year prohibition does not apply, however, if (i) the
corporation's Board of Directors approved the Business Combination or approved
(in advance) the transaction that resulted in 15% ownership, (ii) in the
transaction in which the Interested Stockholder acquired 15% ownership, that
stockholder acquired at least 85% of the voting stock outstanding when the
transaction was initiated (excluding shares owned by officer-directors and
certain employee stock plans); or (iii) the Business Combination subsequently is
approved by the Board of Directors and authorized at a stockholders' meeting by
at least 66-2/3% of the outstanding voting stock, excluding the stock owned by
the Interested Stockholder. In addition, Section 203 does not apply at all if
(i) the corporation's original certificate of incorporation expressly elects to
avoid application of Section 203, (ii) the Board of Directors amended the
corporation's bylaws within 90 days of the effective date of Section 203
expressly to avoid application of Section 203; (iii) the corporation's
stockholders amend the certificate or bylaws to avoid application of Section 203
(although such amendment will not be effective for 12 months); (iv) the
corporation's voting stock is not listed on a national securities exchange,
authorized for quotation on an interdealer quotation system on a registered
national securities association, or held of record by more than 2,000
stockholders (unless the corporation nonetheless elects to be governed by
Section 203); (v) the stockholder acquires 15% ownership inadvertently and then
disposes of sufficient shares to eliminate that status; or (vi) the Business
Combination is proposed after the public announcement, or the publication of
notice, of a proposed business-combination type of transaction and prior to the
consummation or abandonment of such transaction. Because the Board of Directors
of SFC has approved the Merger, the provisions of Section 203 would not apply to
the Merger.
 
     Article Eighth of the SFC Certificate requires that Business Combinations
(as defined therein) between SFC (or any majority-owned subsidiary thereof) and
an "Interested Stockholder" either:
 
     (a) be approved by the vote of the holders of at least 75% of the voting
         power of the then-outstanding shares of stock of SFC entitled to vote 
         in an election of directors, voting together as a single class;
 
     (b) be approved by a majority of the "Disinterested Directors" (as defined
         in Article Eighth); or
 
     (c) involve consideration per share generally equal to that paid by the
         Interested Stockholder when it acquired its block of stock.
 
     Article Eighth defines "Interested Stockholder" as a beneficial owner of at
least 10% of the outstanding voting stock of the corporation, or an affiliate or
assignee of an Interested Stockholder.
 
     Article Eighth does not affect the stockholder voting requirement, if any,
in connection with a business combination that does not involve an Interested
Stockholder. Article Eighth will also generally not affect any stockholder
voting requirement in connection with any business combination if SFC's
stockholders receive consideration which is at least equal to the consideration
previously paid by the Interested Stockholder for its shares of SFC voting stock
or the Fair Market Value of SFC Common Stock on the "Announcement Date" or
"Determination Date" (as defined in Article Eighth), provided that the
consideration received by the stockholders in the combination is not less than
what the SFC stockholders would receive in a liquidation, dissolution, or
winding-up of SFC. Because the Board of Directors of SFC has approved the Merger
(as described in paragraph (b) above), the provisions of Article Eighth do not
apply to the Merger.
 
     The provisions of Article Eighth are designed to encourage any person or
entity seeking to acquire SFC to negotiate with the Board of Directors, with the
goal that any resulting transaction would be structured to provide all of the
stockholders with their pro rata share of any acquisition premium, and that
stockholders would be protected against coercive or unfair purchase offers and
"freeze-out" transactions. Those provisions may have the effect, however, of
discouraging or rendering more difficult takeover attempts not previously
approved by the Board of Directors (including takeover attempts that certain
stockholders may deem to be in their interests), and of perpetuating the
incumbent directors and management.
 
LIMITATIONS ON ABILITY TO VOTE STOCK
 
     UPC.  UPC's Charter and Bylaws do not contain any provision restricting a
stockholder's ability to vote shares of UPC voting stock.
 
                                       44
<PAGE>   53
 
     SFC.  SFC's Certificate of Incorporation contains a provision that
prohibits a person who is the beneficial owner, directly or indirectly, of more
than 10% of SFC Common Stock from voting shares held in excess of the 10% limit
on any matter on which stockholders are entitled to vote.
 
DISSENTERS' RIGHTS OF APPRAISAL
 
     UPC.  Under the TBCA, a stockholder is generally entitled to dissent from a
corporate action, and obtain payment of the fair value of his shares in the
event of: (i) consummation of a plan of merger to which the corporation is a
party, unless stockholder approval is not required by the TBCA; (ii)
consummation of a plan of share exchange to which the corporation is a party as
the corporation whose shares will be acquired if the stockholder is entitled to
vote on the Plan; (iii) consummation of a sale or exchange of substantially all
of the corporation's property other than in the usual and regular course of
business, if the stockholder is entitled to vote on the sale or exchange,
including a sale in dissolution, but not including a sale pursuant to court
order or to a plan by which substantially all of the net proceeds of the sale
will be distributed in cash to the stockholders within one year after the date
of sale; (iv) an amendment of the charter that materially and adversely affects
rights in respect of a dissenter's shares because it (a) alters or abolishes a
preferential right of the shares, (b) creates, alters, or abolishes a right in
respect of redemption of the shares, including a provision respecting a sinking
fund for the redemption or repurchase of the shares, (c) alters or abolishes a
preemptive right of the holder of the shares to acquire shares or other
securities, (d) excludes or limits the right of the shares to vote on any
matter, or to cumulate votes, other than a limitation by dilution through
issuance of shares or other securities with similar voting rights, or (e)
reduces the number of shares owned by the stockholder to a fraction of a share
if the fractional share so created is to be acquired for cash under the TBCA; or
(v) any corporate action taken pursuant to a stockholder vote, to the extent the
charter, bylaws, or a resolution of the board of directors provide that voting
or nonvoting stockholders are entitled to dissent and obtain payment for their
shares. UPC's Charter and Bylaws do not provide for any such additional
dissenters' rights.
 
     SFC.  The rights of appraisal of dissenting stockholders of SFC are
governed by the DGCL. Pursuant thereto, except as described below, any
stockholder has the right to dissent from any merger of which SFC could be a
constituent corporation. No appraisal rights are available, however, for (i) the
shares of any class or series of stock that is either listed on a national
securities exchange, quoted on the Nasdaq/NMS, or held of record by more than
2,000 stockholders or (ii) any shares of stock of the constituent corporation
surviving a merger if the merger did not require the approval of the surviving
corporation's stockholders, unless, in either case, the holders of such stock
are required by an agreement of merger or consolidation to accept for that stock
something other than: (a) shares of stock of the corporation surviving or
resulting from the merger or consolidation; (b) shares of stock of any other
corporation that will be listed at the effective time of the merger on a
national securities exchange, quoted on the Nasdaq/NMS, or held of record by
more than 2,000 stockholders; (c) cash in lieu of fractional shares of stock
described in clause (a) or (b) immediately above; or (d) any combination of the
shares of stock and cash in lieu of fractional shares described in clauses (a)
through (c) immediately above.
 
STOCKHOLDERS' RIGHTS TO EXAMINE BOOKS AND RECORDS
 
     UPC.  The TBCA provides that a stockholder may inspect and copy books and
records during regular business hours, if he or she gives the corporation
written notice of his or her demand at least five business days before the date
of the inspection. The written demand must be made in good faith and for a
proper purpose and must describe with reasonable particularity the purpose of
the request and the records the stockholder desires to inspect.
 
     SFC.  The DGCL similarly provides that a stockholder may inspect books and
records upon written demand under oath stating the purpose of the inspection, if
such purpose is reasonably related to such person's interest as a stockholder.

DIVIDENDS
 
     UPC.  UPC's ability to pay dividends on UPC Common Stock is governed by
Tennessee corporate law. Under Tennessee corporate law, dividends may be paid so
long as the corporation would be able to pay its debts as they become due in the
ordinary course of business and the corporation's total assets would not be less
than the sum of its total liabilities plus the amount that would be needed, if
the corporation were to be dissolved at the time of the distribution, to satisfy
the preferential rights upon dissolution to stockholders whose preferential
rights are superior to those receiving the distribution.
 
     There are various statutory limitations on the ability of UPC's Banking
Subsidiaries to pay dividends to UPC. See "CERTAIN REGULATORY
CONSIDERATIONS -- Payment of Dividends."
 
     SFC.  The DGCL provides that, subject to any restrictions in the
corporation's certificate of incorporation, dividends may be declared from the
corporation's surplus, or, if there is no surplus, from its net profits for the
fiscal year in which the dividend is declared and the preceding fiscal year.
Dividends may not be declared, however, if the corporation's capital has been
diminished to an amount less than the aggregate amount of all capital
represented by the issued and outstanding stock of all classes having a
preference upon the distribution of assets. Substantially all of the funds
available for the payment of dividends by SFC are derived from its subsidiary
depository institution. There are various statutory limitations on the ability
of SFC's subsidiary depository institution to pay dividends to SFC. See "CERTAIN
REGULATORY CONSIDERATIONS -- Payment of Dividends."

     The holders of UPC Common Stock are entitled to receive dividends when and
if declared by the Board of Directors out of funds legally available therefor.
Although UPC currently intends to continue to pay quarterly cash dividends on
the UPC Common Stock, there can be no assurance that UPC's dividend policy will
remain unchanged after completion of the Merger. The declaration and payment of
dividends thereafter will depend upon business conditions, operating results,
capital and reserve requirements, and the Board of Directors' consideration of
other relevant factors. The Agreement provides that SFC may not declare and pay
cash dividends on the shares of SFC Common Stock.
 
     UPC and SFC are each legal entities separate and distinct from their
subsidiaries and their revenues depend in significant part on the payment of
dividends from their subsidiary depository institutions. UPC's and SFC's
subsidiary depository institutions are subject to certain legal restrictions on
the amount of dividends they are permitted to pay. See "CERTAIN REGULATORY
CONSIDERATIONS  --  Payment of Dividends."

                                BUSINESS OF UPC
 
GENERAL
 
     UPC, a Tennessee corporation, is a bank holding company registered with the
Federal Reserve under the BHC Act. As of June 30, 1997, UPC had total
consolidated assets of approximately $14.8 billion, total consolidated loans of
approximately $10.4 billion, total consolidated deposits of approximately $11.2
billion, and total consolidated stockholders' equity of approximately $1.4
billion.
 
     UPC conducts its business activities through its principal bank subsidiary,
the $5.5 billion asset Union Planters National Bank, founded in 1869 and
headquartered in Memphis, Tennessee, 32 other bank subsidiaries and one savings
bank subsidiary located in Tennessee, Mississippi, Missouri, Arkansas,
Louisiana, Alabama, and Kentucky. Through the UPC Banking Subsidiaries, UPC
provides a diversified range of financial services in the communities in which
it operates, including traditional banking services, consumer, commercial and
corporate lending, retail banking, and other financial services traditionally
furnished by full-service financial institutions. UPC also is engaged in
mortgage origination and servicing, investment management and trust services,
the issuance and servicing of credit and debit cards, the origination,
packaging, and securitization of loans, primarily the government-guaranteed
portions of Small Business Administration loans; the purchase of delinquent
FHA/VA government-insured/guaranteed loans from third parties and from GNMA
pools serviced for others; full service and discount brokerage; and the sale of
annuities and bank-eligible insurance products.
 
     Through the UPC Banking Subsidiaries, UPC operates approximately 432
banking offices and 564 ATMs. UPC's total assets at June 30, 1997 are allocable
by state to its banking offices (before consolidating adjustments) approximately
as follows: $9.7 billion in Tennessee, $2.3 billion in Mississippi, $1.2 billion
in Missouri, $800 million in Arkansas, $609 million in Louisiana, $440 million
in Alabama and $113 million in Kentucky.
 
     Acquisitions have been, and are expected to continue to be, an important
part of the expansion of UPC's business. UPC completed twelve acquisitions in
1993, thirteen in 1994, three in 1995 and seven in 1996, adding approximately
$1.7 billion in total assets in 1993, $3.8 billion in 1994, $1.3 billion in 1995
and $4.2 billion in 1996. Thus far in 1997, UPC has entered into definitive
agreements to acquire six financial institutions in addition to SFC which had
aggregate total assets of approximately $3.7 billion at June 30, 1997. For
information with respect to these acquisitions see "-- Recent Developments." For
a discussion of UPC's acquisition program and UPC management's philosophy on
that subject, see the caption "Acquisitions" (on page 6) and Note 2 to UPC's
audited consolidated financial statements for the years ended December 31, 1996,
1995, and 1994 (on pages 45 and 46) contained in UPC's Annual Report to
Stockholders which is Exhibit 13 to UPC's Annual Report on Form 10-K for the
year ended December 31, 1996, which Exhibit 13 is incorporated by reference
herein to the extent indicated herein.
 
     UPC expects to continue to take advantage of the consolidation of the
financial services industry by further developing its franchise through the
acquisition of financial institutions. Future acquisitions may entail
 
                                       48

the payment by UPC of consideration in excess of the book value of the
underlying net assets acquired, may result in the issuance of additional shares
of UPC capital stock or the incurring of additional indebtedness by UPC, and
could have a dilutive effect on the earnings or book value per share of UPC
Common Stock. Moreover, significant charges against earnings are sometimes
required incidental to acquisitions. For a description of acquisitions which are
currently pending, see "-- Recent Developments."
 
     The principal executive offices of UPC are located at 7130 Goodlett Farms

     OTHER ANNOUNCED ACQUISITIONS.  UPC has entered into definitive agreements
to acquire the following two financial institutions in addition to SFC and the
Other Pending Acquisitions (the "Other Announced Acquisitions"). Each of the
Other Announced Acquisitions is subject to shareholder approval, regulatory
approval and the satisfaction of various additional conditions, including the
completion of a due diligence investigation of the two institutions by UPC
during the periods ending as noted below. In each case, in accordance with UPC's
past practice, until satisfaction of the due diligence condition, UPC considers
the acquisitions of the two Other Announced Acquisitions not to be probable for
financial reporting purposes; therefore, neither of the Other Announced
Acquisitions has been included in the "Other Pending Acquisitions" and none of
the pro forma information or other information relating to the impact of these
Other Announced Acquisitions on the financial statements of UPC, such as that
set forth under "SUMMARY -- Equivalent and Pro Forma Per Share Data" or
"-- Recent Developments -- Earnings Considerations Related to Other Pending
Acquisitions" includes or reflects information with respect to either of the
Other Announced Acquisitions. Each of the Other Announced Acquisitions is
structured to qualify as a tax-free reorganization
 
                                       49

and to be accounted for as a pooling of interests. Aggregate charges for the
Other Announced Acquisitions have been preliminarily estimated to be in the
range of $10 to $12 million, after taxes. This estimate is preliminary and
subject to adjustment pending completion of the due diligence process.

     EARNINGS CONSIDERATIONS RELATED TO OTHER PENDING ACQUISITIONS.  It is
expected that either UPC or the institutions to be acquired in connection with
the Other Pending Acquisitions will incur charges arising from such acquisitions
and from the assimilation of those institutions into the UPC organization. Most
of the charges are expected to relate to the Magna Bancorp, Inc. acquisition.
Anticipated charges would normally arise from matters such as, but not limited
to, legal and accounting fees, financial advisory fees, consulting fees, payment
of contractual benefits triggered by a change of control, early retirement and
involuntary separation and related benefits, costs associated with elimination
of duplicate facilities and branch consolidations, data processing charges,
cancellation of vendor contracts, and the potential for additional provisions
for loan losses and similar costs which normally arise from the consolidation of
operational activities.
 
     Each of the Other Pending Acquisitions is expected to be accounted for as a
pooling of interests. UPC currently estimates incurring aggregate charges in the
range of $10 million to $15 million after taxes in connection with the
consummation of the Other Pending Acquisitions and the Merger. To the extent
that UPC's recognition of these acquisition-related charges is contingent upon
consummation of a particular transaction, those charges would be recognized in
the period in which such transaction closes. The range is provided as a
preliminary estimate of the significant charges which may in the aggregate be
required and should be viewed accordingly. These charges are not reflected in
the pro forma consolidated financial statements.
 
                       CERTAIN REGULATORY CONSIDERATIONS
 
     The following discussion sets forth certain of the material elements of the
regulatory framework applicable to banks and bank holding companies and provides
certain specific information related to UPC. A more complete discussion is
included in UPC's Annual Report on Form 10-K for the fiscal year ended December
31, 1996. Information relating to SFC is included in the SFC Annual Report on
Form 10-KSB for the fiscal year ended December 31, 1996. See "AVAILABLE
INFORMATION" and "DOCUMENTS INCORPORATED BY REFERENCE."
 
                                       50
<PAGE>   59
 
GENERAL
 
     UPC is a bank holding company registered with the Federal Reserve under the
BHC Act. As such, UPC and its non-bank subsidiaries are subject to the
supervision, examination, and reporting requirements of the BHC Act and the
regulations of the Federal Reserve. In addition, as a savings and loan holding
company, UPC is also registered with the OTS and is subject to the regulation,
supervision, examination, and reporting requirements of the OTS.
 
     The BHC Act requires every bank holding company to obtain the prior
approval of the Federal Reserve before: (i) it may acquire direct or indirect
ownership or control of any voting shares of any bank if, after such
acquisition, the bank holding company will directly or indirectly own or control
more than 5.0% of the voting shares of the bank; (ii) it or any of its
subsidiaries, other than a bank, may acquire all or substantially all of the
assets of any bank; or (iii) it may merge or consolidate with any other bank
holding company. Similar federal statutes require savings and loan holding
companies and other companies to obtain the prior approval of the OTS before
acquiring direct or indirect ownership or control of a savings association.
 
     The BHC Act further provides that the Federal Reserve may not approve any
transaction that would result in a monopoly or would be in furtherance of any
combination or conspiracy to monopolize or attempt to monopolize the business of
banking in any section of the United States, or the effect of which may be
substantially to lessen competition or to tend to create a monopoly in any
section of the country, or that in any other manner would be in restraint of
trade, unless the anticompetitive effects of the proposed transaction are
clearly outweighed by the public interest in meeting the convenience and needs
of the community to be served. The Federal Reserve is also required to consider
the financial and managerial resources and future prospects of the bank holding
companies and banks concerned and the convenience and needs of the community to
be served. Consideration of financial resources generally focuses on capital
adequacy which is discussed below, and consideration of convenience and needs
issues includes the parties' performance under the Community Reinvestment Act of
1977.
 
     The BHC Act, as amended by the interstate banking provisions of the
Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 ("Interstate
Banking Act"), which became effective in September 1995, repealed the prior
statutory restrictions on interstate acquisitions of banks by bank holding
companies, such that UPC and any other bank holding company located in Tennessee
may now acquire a bank located in any other state, and any bank holding company
located outside Tennessee may lawfully acquire any Tennessee-based bank,
regardless of state law to the contrary, in either case subject to certain
deposit-percentage limitations, aging requirements, and other restrictions. The
Interstate Banking Act also generally provides that, after June 1, 1997,
national and state-chartered banks may branch interstate through acquisitions of
banks in other states. By adopting legislation prior to that date, a state has
the ability either to "opt in" and accelerate the date after which interstate
branching is permissible or "opt out" and prohibit interstate branching
altogether. None of the states in which the banking subsidiaries of UPC or SFC
are located has either moved up the date after which interstate branching will
be permissible or "opted out." Accordingly, UPC is able to consolidate all of
its bank subsidiaries into a single bank with interstate branches.
 
     The BHC Act generally prohibits UPC from engaging in activities other than
banking or managing or controlling banks or other permissible subsidiaries and
from acquiring or retaining direct or indirect control of any company engaged in
any activities other than those activities determined by the Federal Reserve to
be so closely related to banking or managing or controlling banks as to be a
proper incident thereto. In determining whether a particular activity is
permissible, the Federal Reserve must consider whether the performance of such
an activity reasonably can be expected to produce benefits to the public, such
as greater convenience, increased competition, or gains in efficiency, that
outweigh possible adverse effects, such as undue concentration of resources,
decreased or unfair competition, conflicts of interest, or unsound banking
practices. For example, factoring accounts receivable, acquiring or servicing
loans, leasing personal property, conducting discount securities brokerage
activities, performing certain data processing services, acting as agent or
broker in selling credit life insurance and certain other types of insurance in
connection with credit transactions, and performing certain insurance
underwriting activities all have been determined by the Federal Reserve to be
permissible activities of bank holding companies. The BHC Act does not place
territorial limitations on
 
                                       51
<PAGE>   60
 
permissible nonbanking activities of bank holding companies. Despite prior
approval, the Federal Reserve has the power to order a holding company or its
subsidiaries to terminate any activity or to terminate its ownership or control
of any subsidiary when it has reasonable cause to believe that continuation of
such activity or such ownership or control constitutes a serious risk to the
financial safety, soundness, or stability of any bank subsidiary of that bank
holding company.
 
     Each of the subsidiary depository institutions of UPC is a member of the
FDIC, and as such, its deposits are insured by the FDIC to the extent provided
by law. Each such subsidiary is also subject to numerous state and federal
statutes and regulations that affect is business, activities, and operations,
and each is supervised and examined by one or more state or federal bank
regulatory agencies.
 
     The regulatory agencies having supervisory jurisdiction over the respective
subsidiary institutions of UPC and SFC (the FDIC and the applicable state
authority in the case of state-chartered nonmember banks, the OTS in the case of
federally chartered thrift institutions, the Federal Reserve in the case of
state-chartered member banks, and the OCC in the case of national banks)
regularly examine the operations of such institutions and have authority to
approve or disapprove mergers, consolidations, the establishment of branches,
and similar corporate actions. The federal and state banking regulators also
have the power to prevent the continuance or development of unsafe or unsound
banking practices or other violations of law.
 
PAYMENT OF DIVIDENDS
 
     UPC is a legal entity separate and distinct from its banking, thrift, and
other subsidiaries. The principal sources of cash flow of UPC, including cash
flow to pay dividends to its stockholders, are dividends from their subsidiary
depository institutions. There are statutory and regulatory limitations on the
payment of dividends by these subsidiary depository institutions to UPC, as well
as by UPC and SFC to their stockholders.
 
     As to the payment of dividends, each of UPC's state-chartered banking
subsidiaries is subject to the respective laws and regulations of the state in
which such bank is located, and to the regulations of the bank's primary federal
regulator. UPC's subsidiaries that are thrift institutions are subject to the
OTS' capital distributions regulation, and those that are national banks are
subject to the regulations of the OCC.
 
     If, in the opinion of the federal banking regulator, a depository
institution under its jurisdiction is engaged in or is about to engage in an
unsafe or unsound practice (which, depending on the financial condition of the
depository institution, could include the payment of dividends), such agency may
require, after notice and hearing, that such institution cease and desist from
such practice. The federal banking agencies have indicated that paying dividends
that deplete a depository institution's capital base to an inadequate level
would be an unsafe and unsound banking practice. Under the Federal Deposit
Insurance Corporation Improvement Act of 1991 ("FDICIA"), a depository
institution may not pay any dividend if payment would cause it to become
undercapitalized or if it already is undercapitalized. See "-- Prompt Corrective
Action." Moreover, the federal agencies have issued policy statements that
provide that bank holding companies and insured banks should generally only pay
dividends out of current operating earnings.
 
     At June 30, 1997, under dividend restrictions imposed under federal and
state laws, the subsidiary depository institutions of UPC, without obtaining
governmental approvals, could declare aggregate dividends to UPC of
approximately $142.4 million.
 
     The payment of dividends by UPC and its banking subsidiaries may also be
affected or limited by other factors, such as the requirement to maintain
adequate capital above regulatory guidelines.
 
CAPITAL ADEQUACY
 
     UPC and its subsidiary depository institutions are required to comply with
the capital adequacy standards established by the Federal Reserve in the case of
UPC, and the appropriate federal banking regulator in the case of each of its
subsidiary depository institutions. There are two basic measures of capital
adequacy for bank holding companies and their subsidiary depository institutions
that have been promulgated by the Federal Reserve and each of the federal bank
regulatory agencies: a risk-based measure and a leverage
 
                                       52

measure. All applicable capital standards must be satisfied for a bank holding
company to be considered in compliance.
 
     The risk-based capital standards are designed to make regulatory capital
requirements more sensitive to differences in risk profile among depository
institutions and bank holding companies, to account for off-balance-sheet
exposure, and to minimize disincentives for holding liquid assets. Assets and
off-balance-sheet items are assigned to broad risk categories, each with
appropriate weights. The resulting capital ratios represent capital as a
percentage of total risk-weighted assets and off-balance-sheet items.
 
     The minimum guideline for the ratio ("Total Capital Ratio") of total
capital ("Total Capital") to risk-weighted assets (including certain
off-balance-sheet items, such as standby letters of credit) is 8.0%. At least
half of Total Capital must be composed of common equity, undivided profits,
minority interests in the equity accounts of consolidated subsidiaries,
noncumulative perpetual preferred stock, and a limited amount of cumulative
perpetual preferred stock, less goodwill and certain other intangible assets
("Tier 1 Capital"). The remainder may consist of subordinated debt, other
preferred stock, and a limited amount of loan loss reserves ("Tier 2 Capital").
At June 30, 1997, UPC's consolidated Total Capital Ratio and its Tier 1 Capital
Ratio (i.e., the ratio of Tier 1 Capital to risk-weighted assets) were 19.86%
and 16.76%, respectively.
 
     In addition, the Federal Reserve has established minimum leverage ratio
guidelines for bank holding companies. These guidelines provide for a minimum
ratio (the "Leverage Ratio") of Tier 1 Capital to average assets, less goodwill
and certain other intangible assets, of 3.0% for bank holding companies that
meet certain specified criteria, including having the highest regulatory rating.
All other bank holding companies generally are required to maintain a Leverage
Ratio of at least 3.0%, plus an additional cushion of 100 to 200 basis points.
UPC's Leverage Ratio at June 30, 1997, was 10.64%. The guidelines also provide
that bank holding companies experiencing internal growth or making acquisitions
will be expected to maintain strong capital positions substantially above the
minimum supervisory levels without significant reliance on intangible assets.
Furthermore, the Federal Reserve has indicated that it will consider a "tangible
Tier 1 Capital Leverage Ratio" (deducting all intangibles) and other indicia of
capital strength in evaluating proposals for expansion or new activities.
 
     Each of UPC's subsidiary depository institutions is subject to risk-based
and leverage capital requirements adopted by its federal banking regulatory,
which are substantially similar to those adopted by the Federal Reserve for bank
holding companies. Each of the subsidiary depository institutions was in
compliance with applicable minimum capital requirements as of June 30, 1997.
Neither UPC nor any of its subsidiary depository institutions has been advised
by any federal banking agency of any specific minimum capital ratio requirement
applicable to it.
 
     Failure to meet capital guidelines could subject a bank or thrift to a
variety of enforcement remedies, including issuance of a capital directive, the
termination of deposit insurance by the FDIC, a prohibition on the taking of
brokered deposits, and certain other restrictions on its business. As described
below, substantial additional restrictions can be imposed upon FDIC-insured
depository institutions that fail to meet applicable capital requirements. See
"-- Prompt Corrective Action."
 
     The federal bank regulators continue to indicate their desire to raise
capital requirements applicable to banking organizations beyond their current
levels. In this regard, the Federal Reserve, the FDIC and the OCC have, pursuant
to FDICIA, proposed an amendment to the risk-based capital standards that would
calculate the change in an institution's net economic value attributable to
increases and decreases in market interest rates and would require banks with
excessive interest rate risk exposure to hold additional amounts of capital
against such exposures. The OTS has already included an interest-rate risk
component in its risk-based capital guidelines for savings associations that it
regulates.
 
SUPPORT OF SUBSIDIARY INSTITUTIONS
 
     Under Federal Reserve policy, UPC is expected to act as a source of
financial strength for, and to commit resources to support, each of its banking
subsidiaries. This support may be required at times when, absent such Federal
Reserve policy, UPC may not be inclined to provide it. In addition, any capital
loans by a bank
 
                                       53
<PAGE>   62
 
holding company to any of its banking subsidiaries are subordinate in right of
payment to deposits and to certain other indebtedness of such banks. In the
event of a bank holding company's bankruptcy, any commitment by the bank holding
company to a federal bank regulatory agency to maintain the capital of a banking
subsidiary will be assumed by the bankruptcy trustee and entitled to a priority
of payment.
 
     Under the Federal Deposit Insurance Act (the "FDIA"), a depository
institution insured by the FDIC can be held liable for any loss incurred by, or
reasonably expected to be incurred by, the FDIC after August 9, 1989, in
connection with (i) the default of a commonly controlled FDIC-insured depository
institution or (ii) any assistance provided by the FDIC to any commonly
controlled FDIC-insured depository institution "in danger of default." "Default"
is defined generally as the appointment of a conservator or receiver, and "in
danger of default" is defined generally as the existence of certain conditions
indicating that a default is likely to occur in the absence of regulatory
assistance. The FDIC's claim for damages is superior to claims of stockholders
of the insured depository institution or its holding company, but is subordinate
to claims of depositors, secured creditors, and holders of subordinated debt
(other than affiliates) of the commonly controlled insured depository
institution. The subsidiary depository institutions of UPC are subject to these
cross-guarantee provisions. As a result, any loss suffered by the FDIC in
respect of any of these subsidiaries would likely result in assertion of the
cross-guarantee provisions, the assessment of such estimated losses against the
depository institution's banking or thrift affiliates, and a potential loss of
UPC's respective investments in such other subsidiary depository institutions.
 
PROMPT CORRECTIVE ACTION
 
     FDICIA establishes a system of prompt corrective action to resolve the
problems of undercapitalized institutions. Under this system, which became
effective in December 1992, the federal banking regulators are required to
establish five capital categories (well capitalized, adequately capitalized,
undercapitalized, significantly undercapitalized, and critically
undercapitalized) and to take certain mandatory supervisory actions, and are
authorized to take other discretionary actions, with respect to institutions in
the three undercapitalized categories, the severity of which will depend upon
the capital category in which the institution is placed. Generally, subject to a
narrow exception, FDICIA requires the banking regulator to appoint a receiver or
conservator for an institution that is critically undercapitalized. The federal
banking agencies have specified by regulation the relevant capital level for
each category.
 
     Under the final agency rules implementing the prompt corrective action
provisions, an institution that (i) has a Total Capital Ratio of 10% or greater,
a Tier 1 Capital Ratio of 6.0% or greater, and a Leverage Ratio of 5.0% or
greater and (ii) is not subject to any written agreement, order, capital
directive, or prompt corrective action directive issued by the appropriate
federal banking agency is deemed to be well capitalized. An institution with a
Total Capital Ratio of 8.0% or greater, a Tier 1 Capital Ratio of 4.0% or
greater, and a Leverage Ratio of 4.0% or greater is considered to be adequately
capitalized. A depository institution that has a Total Capital Ratio of less
than 8.0%, a Tier 1 Capital Ratio of less than 4.0%, or a Leverage Ratio of less
than 4.0% is considered to be undercapitalized. A depository institution that
has a Total Capital Ratio of less than 6.0%, a Tier 1 Capital Ratio of less than
3.0%, or a Leverage Ratio of less than 3.0% is considered to be significantly
undercapitalized, and an institution that has a tangible equity capital to
assets ratio equal to or less than 2.0% is deemed to be critically
undercapitalized. For purposes of the regulation, the term "tangible equity"
includes core capital elements counted as Tier 1 Capital for purposes of the
risk-based capital standards, plus the amount of outstanding cumulative
perpetual preferred stock (including related surplus), minus all intangible
assets with certain exceptions. A depository institution may be deemed to be in
a capitalization category that is lower than is indicated by its actual capital
position if it receives an unsatisfactory examination rating.
 
     An institution that is categorized as undercapitalized, significantly
undercapitalized, or critically undercapitalized is required to submit an
acceptable capital restoration plan to its appropriate federal banking agency.
Under FDICIA, a bank holding company must guarantee that a subsidiary depository
institution meet its capital restoration plan, subject to certain limitations.
The obligation of a controlling bank holding company under FDICIA to fund a
capital restoration plan is limited to the lesser of 5.0% of an undercapitalized
subsidiary's assets or the amount required to meet regulatory capital
requirements. An undercapitalized
 
                                       54
<PAGE>   63
 
institution is also generally prohibited from increasing its average total
assets, making acquisitions, establishing any branches, or engaging in any new
line of business, except in accordance with an accepted capital restoration plan
or with the approval of the FDIC. In addition, the appropriate federal banking
agency is given authority with respect to any undercapitalized depository
institution to take any of the actions it is required to or may take with
respect to a significantly undercapitalized institution as described below if it
determines "that those actions are necessary to carry out the purpose" of
FDICIA.
 
     For those institutions that are significantly undercapitalized or
undercapitalized and either fail to submit an acceptable capital restoration
plan or fail to implement an approved capital restoration plan, the appropriate
federal banking agency must require the institution to take one or more of the
following actions: (i) sell enough shares, including voting shares, to become
adequately capitalized; (ii) merge with (or be sold to) another institution (or
holding company), but only if grounds exist for appointing a conservator or
receiver; (iii) restrict certain transactions with banking affiliates as if the
"sister bank" exception to the requirements of Section 23A of the Federal
Reserve Act did not exist; (iv) otherwise restrict transactions with bank or
non-bank affiliates; (v) restrict interest rates that the institution pays on
deposits to "prevailing rates" in the institution's "region;" (vi) restrict
asset growth or reduce total assets; (vii) alter, reduce, or terminate
activities; (viii) hold a new election of directors; (ix) dismiss any director
or senior executive officer who held office for more than 180 days immediately
before the institution became undercapitalized, provided that in requiring
dismissal of a director or senior officer, the agency must comply with certain
procedural requirements, including the opportunity for an appeal in which the
director or officer will have the burden of proving his or her value to the
institution; (x) employ "qualified" senior executive officers; (xi) cease
accepting deposits from correspondent depository institutions; (xii) divest
certain nondepository affiliates which pose a danger to the institution; or
(xiii) be divested by a parent holding company. In addition, without the prior
approval of the appropriate federal banking agency, a significantly
undercapitalized institution may not pay any bonus to any senior executive
officer or increase the rate of compensation for such an officer.
 
     At June 30, 1997, all of the subsidiary depository institutions of UPC had
the requisite capital levels to qualify as well capitalized.
 
                        DESCRIPTION OF UPC CAPITAL STOCK
 
     UPC's Charter currently authorizes the issuance of 100,000,000 shares of
UPC Common Stock and 10,000,000 shares of UPC Preferred Stock. As of July 31,
1997, 66,928,481 shares of UPC Common Stock were issued and outstanding and
approximately 2,907,000 shares were subject to issuance through the exercise of
options granted pursuant to UPC's 1992 and 1983 Stock Option Plans and other
employee, officer and director benefit plans; approximately 3,254,000 shares
were authorized for issuance pursuant to said plans but not yet subject to
option grants or otherwise issued; and approximately 3,015,723 shares were
authorized for issuance and reserved for conversion of certain outstanding
shares of UPC Preferred Stock. In addition, as of July 31, 1997, 2,412,578
shares of UPC's 8% Cumulative, Convertible Preferred Stock, Series E (the
"Series E Preferred Stock") were issued and outstanding. As of July 31, none of
UPC's 750,000 authorized shares of Series A Preferred Stock were issued and
outstanding nor is management aware of the existence of circumstances from which
it may be inferred that such issuance is imminent. THE CAPITAL STOCK OF UPC DOES
NOT REPRESENT OR CONSTITUTE A DEPOSIT ACCOUNT AND IS NOT INSURED BY THE FDIC,
THE BANK INSURANCE FUND, THE SAVINGS ASSOCIATION INSURANCE FUND OR ANY
GOVERNMENTAL AGENCY.
 
UPC COMMON STOCK
 
     GENERAL.  Shares of UPC Common Stock may be issued at such time or times
and for such consideration (not less than the par value thereof) as the UPC
Board of Directors may deem advisable, subject to such limitations as may be set
forth in the laws of the State of Tennessee, UPC's Charter or Bylaws or the
rules of the NYSE. Union Planters National Bank, a wholly-owned, first-tier
subsidiary of UPC, is the Registrar, Transfer Agent and Dividend Disbursing
Agent for shares of UPC Common Stock. Its address is Union
 
                                       55
<PAGE>   64
 
Planters National Bank, Corporate Trust Department, 6200 Poplar Avenue, Third
Floor, Memphis, Tennessee 38119. Its mailing address is P.O. Box 387, Memphis,
Tennessee 38147.
 
     DIVIDENDS.  Subject to the preferential dividend rights applicable to
outstanding shares of the UPC Preferred Stock and subject to applicable
requirements, if any, with respect to the setting aside of sums for purchase,
retirement or sinking funds, if any, for all outstanding UPC Preferred Stock,
the holders of the UPC Common Stock are entitled to receive, to the extent
permitted by law, only such dividends as may be declared from time to time by
the UPC Board of Directors.
 
     UPC has the right to, and may from time to time, enter into borrowing
arrangements or issue other debt instruments, the provisions of which may
contain restrictions on payment of dividends and other distributions on UPC
Common Stock and UPC Preferred Stock; however, UPC has no such arrangements in
effect at the date hereof.
 
     LIQUIDATION RIGHTS.  In the event of the voluntary or involuntary
liquidation, dissolution, distribution of assets or winding-up of UPC, after
distribution in full of the preferential amounts required to be distributed to
the holders of UPC Preferred Stock, holders of UPC Common Stock will be entitled
to receive all of the remaining assets of UPC, of whatever kind, available for
distribution to stockholders ratably in proportion to the number of shares of
UPC Common Stock held. The UPC Board of Directors may distribute in kind to the
holders of UPC Common Stock such remaining assets of UPC or may sell, transfer
or otherwise dispose of all or any part of such remaining assets to any other
person or entity and receive payment therefor in cash, stock or obligations of
such other person or entity, and may sell all or any part of the consideration
so received and distribute any balance thereof in kind to holders of UPC Common
Stock. Neither the merger or consolidation of UPC into or with any other
corporation, nor the merger of any other corporation into UPC, nor any purchase
or redemption of shares of stock of UPC of any class, shall be deemed to be a
dissolution, liquidation or winding-up of UPC for purposes of this paragraph.
 
     Because UPC is a holding company, its right and the rights of its creditors
and stockholders, including the holders of UPC Preferred Stock and UPC Common
Stock, to participate in the distribution of assets of a subsidiary on its
liquidation or recapitalization may be subject to prior claims of such
subsidiary's creditors except to the extent that UPC itself may be a creditor
having recognized claims against such subsidiary.
 
UPC PREFERRED STOCK
 
     SERIES A PREFERRED STOCK.  UPC's Charter provides for the issuance of up to
750,000 shares (subject to adjustment by action of the UPC Board of Directors)
of Series A Preferred Stock under certain circumstances involving a potential
change in control of UPC. None of such shares are outstanding and management is
aware of no facts suggesting that issuance of such shares may be imminent. The
Series A Preferred Stock is described in more detail in UPC's Registration
Statement on Form 8-A, dated January 19, 1989, and filed February 1, 1989 (SEC
File No. 0-6919) which is incorporated by reference herein.
 
     SERIES E PREFERRED STOCK.  2,412,578 shares of Series E Preferred Stock
were outstanding as of July 31, 1997. All shares of Series E Preferred Stock
have a stated value of $25.00 per share. Dividends are payable at the rate of
$0.50 per share per quarter and are cumulative. The Series E Preferred Stock is
convertible at the rate of 1.25 shares of UPC Common Stock for each share of
Series E Preferred Stock. The Series E Preferred Stock is not subject to any
sinking fund provisions and has no preemptive rights. Such shares have a
liquidation preference of $25.00 per share plus unpaid dividends accrued thereon
and, at UPC's option and with the prior approval of the Federal Reserve, are
subject to redemption by UPC at any time at a redemption price of $25.00 per
share plus any unpaid dividends. Holders of Series E Preferred Stock have no
voting rights except as required by law and in certain other limited
circumstances. See "CERTAIN REGULATORY CONSIDERATIONS -- Payment of Dividends."
 
     For a further description of UPC Common Stock, See "EFFECT OF THE MERGER ON
RIGHTS OF STOCKHOLDERS."

                      AGREEMENT AND PLAN OF REORGANIZATION
 
     THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is made and
entered into as of June 23, 1997, by and between SHO-ME FINANCIAL CORP. ("SFC"),
a Delaware corporation having its principal office located in Mt. Vernon,
Missouri; and UNION PLANTERS CORPORATION ("UPC"), a Tennessee corporation having
its principal office located in Memphis, Tennessee.
 
                                    PREAMBLE
 
     The Boards of Directors of SFC and UPC are of the opinion that the
transactions described herein are in the best interests of the parties and their
respective shareholders. This Agreement provides for the acquisition of SFC by
UPC pursuant to the merger of a wholly-owned, first-tier subsidiary of UPC to be
organized under the Laws of the State of Delaware ("UPC Merger Subsidiary") with
and into SFC. At the effective time of such merger, the outstanding shares of
the common stock of SFC shall be converted into the right to receive shares of
the common stock of UPC (except as provided in Sections 3.3 and 3.4 of this
Agreement). As a result, shareholders of SFC shall become shareholders of UPC
and SFC shall continue to conduct its business and operations as a wholly-owned
subsidiary of UPC. The transactions described in this Agreement are subject to
the approvals of the shareholders of UPC and SFC, the Board of Governors of the
Federal Reserve System, and other applicable federal and state regulatory
authorities, and the satisfaction of certain other conditions described in this
Agreement. It is the intention of the parties to this Agreement that the Merger
for federal income tax purposes shall qualify as a "reorganization" within the
meaning of Section 368(a) of the Internal Revenue Code.
 
     Immediately after the execution and delivery of this Agreement, as a
condition and inducement to UPC's willingness to enter into this Agreement, SFC
and UPC are entering into a stock option agreement pursuant to which SFC is
granting to UPC an option to purchase shares of SFC Common Stock.
 
     Certain terms used in this Agreement are defined in Section 11.1 of this
Agreement.
 
     NOW, THEREFORE, in consideration of the above and the mutual warranties,
representations, covenants, and agreements set forth herein, the parties agree
as follows:
 
                                   ARTICLE 1
                        TRANSACTIONS AND TERMS OF MERGER
 
     1.1  MERGER.  Subject to the terms and conditions of this Agreement, at the
Effective Time, UPC Merger Subsidiary shall be merged with and into SFC in
accordance with the provisions of Section 251 of the DGCL and with the effect
provided in Section 259 of the DGCL (the "Merger"). SFC shall be the Surviving
Corporation resulting from the Merger and shall continue to be governed by the
Laws of the State of Delaware. The Merger shall be consummated pursuant to the
terms of this Agreement, which has been approved and adopted by the respective
Boards of Directors of SFC and UPC and the Plan of Merger, in substantially the
form of Exhibit 1, which has been approved and adopted by the Board of Directors
of SFC and will be approved and adopted by the Board of Directors of UPC Merger
Subsidiary and UPC (in its capacity as sole shareholder of UPC Merger
Subsidiary) upon the organization of UPC Merger Subsidiary.
 
     1.2  TIME AND PLACE OF CLOSING.  The Closing will take place at 9:00 A.M.
on the date that the Effective Time occurs (or the immediately preceding day if
the Effective Time is earlier than 9:00 A.M.), or at such other time as the
Parties, acting through their chief executive officers or chief financial
officers, may mutually agree. The Closing shall be held at such place as may be
mutually agreed upon by the Parties.
 
     1.3  EFFECTIVE TIME.  The Merger and other transactions contemplated by
this Agreement shall become effective on the date and at the time the
Certificate of Merger reflecting the Merger shall become effective with the
Secretary of State of the State of Delaware (the "Effective Time"). Subject to
the terms and conditions hereof, unless otherwise mutually agreed upon in
writing by the chief executive officers or chief financial officers of each
Party, the Parties shall use their reasonable efforts to cause the Effective
Time to occur on such date as may be designated by UPC within 30 days following
the last to occur of (i) the effective
 
                                       A-5
<PAGE>   71
 
date (including expiration of any applicable waiting period) of the last
required Consent of any Regulatory Authority having authority over and approving
or exempting the Merger, (ii) the date on which the shareholders of SFC approve
this Agreement and the Plan of Merger as required by applicable Law, and (iii)
the date on which all other conditions precedent to each Party's obligations
hereunder shall have been satisfied or waived (to the extent waivable by such
Party).
 
     1.4  EXECUTION OF STOCK OPTION AGREEMENT.  Simultaneously with the
execution of this Agreement by the Parties and as a condition hereto, SFC is
executing and delivering to UPC a stock option agreement (the "Stock Option
Agreement"), in substantially the form of Exhibit 2, pursuant to which SFC is
granting to UPC an option to purchase shares of SFC Common Stock.
 
     1.5  RESTRUCTURE OF TRANSACTION.  UPC shall, in its reasonable discretion,
have the unilateral right to revise the structure of the Merger contemplated by
this Agreement in order to achieve tax benefits or for any other reason which
UPC may deem advisable; provided, however, that UPC shall not have the right,
without the approval of the Board of Directors of SFC, to make any revision to
the structure of the Merger which: (i) changes the amount of the consideration
which the holders of shares of SFC Common Stock are entitled to receive
(determined in the manner provided in Section 3.1 of this Agreement); (ii)
changes the intended tax-free effects of the Merger to UPC or the holders of
shares of SFC Common Stock; (iii) would permit UPC to pay the consideration
other than by delivery of UPC Common Stock registered with the SEC (in the
manner described in Section 4.1 of this Agreement); (iv) would be materially
adverse to the interests of SFC or holders of shares of SFC Common Stock; (v)
would unreasonably impede or delay consummation of the Merger; or (vi) would
affect any of the provisions in Sections 8.13 or 8.14 of this Agreement. UPC may
exercise this right of revision by giving written notice to SFC in the manner
provided in Section 11.8 of this Agreement which notice shall be in the form of
an amendment to this Agreement or in the form of an Amended and Restated
Agreement and Plan of Merger.
 
                                   ARTICLE 2
                                TERMS OF MERGER
 
     2.1  CHARTER.  The Charter of SFC in effect immediately prior to the
Effective Time shall be the Charter of the Surviving Corporation until otherwise
amended or repealed.
 
     2.2  BY-LAWS.  The By-laws of SFC in effect immediately prior to the
Effective Time shall be the By-laws of the Surviving Corporation until otherwise
amended or repealed.
 
                                   ARTICLE 3
                          MANNER OF CONVERTING SHARES
 
     3.1  CONVERSION OF SHARES.  Subject to the provisions of this Article 3, at
the Effective Time, by virtue of the Merger and without any action on the part
of UPC, UPC Merger Subsidiary, SFC, or the shareholders of either of the
foregoing, the shares of the constituent corporations shall be converted as
follows:
 
          (a) Each share of UPC Capital Stock, including any associated UPC
     Rights, issued and outstanding immediately prior to the Effective Time
     shall remain issued and outstanding from and after the Effective Time.
 
          (b) Each share of UPC Merger Subsidiary Common Stock issued and
     outstanding immediately prior to the Effective Time shall cease to be
     outstanding and shall be converted into and exchanged for one share of SFC
     Common Stock.
 
          (c) Each share of SFC Common Stock (excluding shares held by any SFC
     Company or any UPC Company, in each case other than in a fiduciary capacity
     or as a result of debts previously contracted) issued and outstanding at
     the Effective Time shall cease to be outstanding and shall be converted
     into and exchanged for the right to receive .7694 of a share of UPC Common
     Stock (as subject to possible adjustment as set forth in Section 10.1(g) of
     this Agreement, the "Exchange Ratio"). Pursuant to the
 
                                       A-6
<PAGE>   72
 
     UPC Rights Agreement, each share of UPC Common Stock issued in connection
     with the Merger upon conversion of SFC Common Stock shall be accompanied by
     a UPC Right.
 
     3.2  ANTI-DILUTION PROVISIONS.  In the event UPC changes the number of
shares of UPC Common Stock issued and outstanding prior to the Effective Time as
a result of a stock split, stock dividend, or similar recapitalization with
respect to such stock and the record date therefor (in the case of a stock
dividend) or the effective date thereof (in the case of a stock split or similar
recapitalization for which a record date is not established) shall be prior to
the Effective Time, the Exchange Ratio shall be proportionately adjusted.
 
     3.3  SHARES HELD BY SFC OR UPC.  Each of the shares of SFC Common Stock
held by any SFC Company or by any UPC Company, in each case other than in a
fiduciary capacity or as a result of debts previously contracted, shall be
canceled and retired at the Effective Time and no consideration shall be issued
in exchange therefor.
 
     3.4  FRACTIONAL SHARES.  Notwithstanding any other provision of this
Agreement, each holder of shares of SFC Common Stock exchanged pursuant to the
Merger who would otherwise have been entitled to receive a fraction of a share
of UPC Common Stock (after taking into account all certificates delivered by
such holder) shall receive, in lieu thereof, cash (without interest) in an
amount equal to such fractional part of a share of UPC Common Stock multiplied
by the market value of one share of UPC Common Stock at the Effective Time. The
market value of one share of UPC Common Stock at the Effective Time shall be the
closing price of such common stock on the NYSE-Composite Transactions List (as
reported by The Wall Street Journal or, if not reported thereby, any other
authoritative source selected by UPC) on the last trading day preceding the
Effective Time. No such holder will be entitled to dividends, voting rights, or
any other rights as a shareholder in respect of any fractional shares.
 
     3.5  CONVERSION OF STOCK OPTIONS.
 
          (a) At the Effective Time, each option to purchase or other right with
     respect to shares of SFC Common Stock pursuant to stock options, stock
     appreciation rights or other rights, including stock awards ("SFC Options")
     granted by SFC under the SFC Stock Plans, which are outstanding at the
     Effective Time, whether or not exercisable, shall be converted into and
     become rights with respect to UPC Common Stock, and UPC shall assume each
     SFC Option, in accordance with the terms of the SFC Stock Plan and stock
     option or other agreement by which it is evidenced, except that from and
     after the Effective Time, (i) UPC and its Salary and Benefits Committee
     shall be substituted for SFC and the Committee of SFC's Board of Directors
     (including, if applicable, the entire Board of Directors of SFC) or other
     independent committee administering such SFC Stock Plan, (ii) each SFC
     Option assumed by UPC may be exercised solely for shares of UPC Common
     Stock, (iii) the number of shares of UPC Common Stock subject to such SFC
     Option shall be equal to the number of shares of SFC Common Stock subject
     to such SFC Option immediately prior to the Effective Time multiplied by
     the Exchange Ratio and rounding down to the nearest whole share, and (iv)
     the per share exercise price under each such SFC Option shall be adjusted
     by dividing the per share exercise price under each such SFC Option by the
     Exchange Ratio and rounding up to the nearest cent. Notwithstanding the
     clauses (iii) and (iv) of the first sentence of this Section 3.5, each SFC
     Option which is an "incentive stock option" shall be adjusted as required
     by Section 424 of the Internal Revenue Code, and the regulations
     promulgated thereunder, so as not to constitute a modification, extension
     or renewal of the option, within the meaning of Section 424(h) of the
     Internal Revenue Code. UPC and SFC agree to take all necessary steps to
     effectuate the foregoing provisions of this Section 3.5.
 
          (b) As soon as practicable after the Effective Time, UPC shall deliver
     to the participants in each SFC Stock Plan an appropriate notice setting
     forth such participant's rights pursuant thereto and the grants subject to
     such SFC Stock Plan shall continue in effect on the same terms and
     conditions (subject to the adjustments required by Section 3.5(a) after
     giving effect to the Merger), and UPC shall comply with the terms of each
     SFC Stock Plan to ensure, to the extent required by, and subject to the
     provisions of, such SFC Stock Plan, that SFC Options which qualified as
     incentive stock options prior to the Effective Time continue to qualify as
     incentive stock options after the Effective Time. Within 45 days after the
     Effective Time, UPC shall file a registration statement on Form S-3 or Form
     S-8, as the case
 
                                       A-7
<PAGE>   73
 
     may be (or any successor or other appropriate forms), with respect to the
     shares of UPC Common Stock subject to such options and shall use its
     reasonable efforts to maintain the effectiveness of such registration
     statements (and maintain the current status of the prospectus or
     prospectuses contained therein) for so long as such options remain
     outstanding.
 
                                   ARTICLE 4
                               EXCHANGE OF SHARES
 
     4.1  EXCHANGE PROCEDURES.  Promptly after the Effective Time, UPC and SFC
shall cause the exchange agent selected by UPC (the "Exchange Agent") to mail to
the former shareholders of SFC appropriate transmittal materials (which shall
specify that delivery shall be effected, and risk of loss and title to the
certificates theretofore representing shares of SFC Common Stock shall pass,
only upon proper delivery of such certificates to the Exchange Agent). The
Exchange Agent may establish reasonable and customary rules and procedures in
connection with its duties. After the Effective Time, each holder of shares of
SFC Common Stock (other than shares to be canceled pursuant to Section 3.3 of
this Agreement) issued and outstanding at the Effective Time shall surrender the
certificate or certificates representing such shares to the Exchange Agent and
shall promptly upon surrender thereof receive in exchange therefor the
consideration provided in Section 3.1 of this Agreement, together with all
undelivered dividends or distributions in respect of such shares (without
interest thereon) pursuant to Section 4.2 of this Agreement. To the extent
required by Section 3.4 of this Agreement, each holder of shares of SFC Common
Stock issued and outstanding at the Effective Time also shall receive, upon
surrender of the certificate or certificates representing such shares, cash in
lieu of any fractional share of UPC Common Stock to which such holder may be
otherwise entitled (without interest). UPC shall not be obligated to deliver the
consideration to which any former holder of SFC Common Stock is entitled as a
result of the Merger until such holder surrenders such holder's certificate or
certificates representing the shares of SFC Common Stock for exchange as
provided in this Section 4.1. The certificate or certificates of SFC Common
Stock so surrendered shall be duly endorsed as the Exchange Agent may require.
Any other provision of this Agreement notwithstanding, neither UPC nor the
Exchange Agent shall be liable to a holder of SFC Common Stock for any amounts
paid or property delivered in good faith to a public official pursuant to any
applicable abandoned property Law. Adoption of this Agreement by the
shareholders of SFC shall constitute ratification of the appointment of the
Exchange Agent.
 
     4.2  RIGHTS OF FORMER SFC SHAREHOLDERS.  At the Effective Time, the stock
transfer books of SFC shall be closed as to holders of SFC Common Stock
immediately prior to the Effective Time and no transfer of SFC Common Stock by
any such holder shall thereafter be made or recognized. Until surrendered for
exchange in accordance with the provisions of Section 4.1 of this Agreement,
each certificate theretofore representing shares of SFC Common Stock (other than
shares to be canceled pursuant to Section 3.3 of this Agreement) shall from and
after the Effective Time represent for all purposes only the right to receive
the consideration provided in Sections 3.1 and 3.4 of this Agreement in exchange
therefor, subject, however, to the Surviving Corporation's obligation to pay any
dividends or make any other distributions with a record date prior to the
Effective Time which have been declared or made by SFC in respect of such shares
of SFC Common Stock in accordance with the terms of this Agreement and which
remain unpaid at the Effective Time. Whenever a dividend or other distribution
is declared by UPC on the UPC Common Stock, the record date for which is at or
after the Effective Time, the declaration shall include dividends or other
distributions on all shares of UPC Common Stock issuable pursuant to this
Agreement, but beginning 30 days after the Effective Time no dividend or other
distribution payable to the holders of record of UPC Common Stock as of any time
subsequent to the Effective Time shall be delivered to the holder of any
certificate representing shares of SFC Common Stock issued and outstanding at
the Effective Time until such holder surrenders such certificate for exchange as
provided in Section 4.1 of this Agreement. However, upon surrender of such SFC
Common Stock certificate, both the UPC Common Stock certificate (together with
all such undelivered dividends or other distributions without interest) and any
undelivered dividends and cash payments payable hereunder (without interest)
shall be delivered and paid with respect to each share represented by such
certificate.

                                   ARTICLE 5
                     REPRESENTATIONS AND WARRANTIES OF SFC
 
     SFC hereby represents and warrants to UPC as follows:
 
     5.1  ORGANIZATION, STANDING, AND POWER.  SFC is a corporation duly
organized, validly existing, and in good standing under the Laws of the State of
Delaware, and has the corporate power and authority to carry on its business as
now conducted and to own, lease, and operate its Assets. SFC is duly qualified
or licensed to transact business as a foreign corporation in good standing in
the States of the United States and foreign jurisdictions where the character of
its Assets or the nature or conduct of its business requires it to be so
qualified or licensed, except for such jurisdictions in which the failure to be
so qualified or licensed is not reasonably likely to have, individually or in
the aggregate, a Material Adverse Effect on SFC.
 
     5.2  AUTHORITY; NO BREACH BY AGREEMENT.
 
          (a) SFC has the corporate power and authority necessary to execute,
     deliver, and perform its obligations under this Agreement and the Plan of
     Merger and to consummate the transactions contemplated hereby and thereby.
     The execution, delivery, and performance of this Agreement and the Plan of
     Merger, as appropriate, and the consummation of the transactions
     contemplated herein and therein, including the Merger, have been duly and
     validly authorized by all necessary corporate action in respect thereof on
     the part of SFC, subject to the approval of this Agreement and the Plan of
     Merger by the holders of a majority of the outstanding shares of SFC Common
     Stock, which is the only shareholder vote required for approval of this
     Agreement and the Plan of Merger and consummation of the Merger by SFC.
     Subject to such requisite shareholder approval, this Agreement and the Plan
     of Merger (which for purposes of this sentence shall not include the Stock
     Option Agreement) represent legal, valid, and binding obligations of SFC,
     enforceable against SFC in accordance with their respective terms (except
     in all cases as such enforceability may be limited by applicable
     bankruptcy, insolvency, reorganization, receivership, conservatorship,
     moratorium, or similar Laws affecting the enforcement of creditors' rights
     generally and except that the availability of the equitable remedy of
     specific performance or injunctive relief is subject to the discretion of
     the court before which any proceeding may be brought).
 
          (b) Except as set forth in Section 5.2 of the SFC Disclosure
     Memorandum, neither the execution and delivery of this Agreement or the
     Plan of Merger, as appropriate, by SFC, nor the consummation by SFC of the
     transactions contemplated hereby or thereby, nor compliance by SFC with any
     of the provisions hereof or thereof, will (i) conflict with or result in a
     breach of any provision of SFC's Charter or By-laws, or (ii) constitute or
     result in a Default under, or require any Consent pursuant to, or result in
     the creation of any Lien on any material Asset of any SFC Company under,
     any Contract or Permit of any SFC Company, other than Defaults that are not
     reasonably likely to have, individually or in the aggregate, a Material
     Adverse Effect on SFC, or (iii) subject to receipt of the requisite
     Consents referred to in Section 9.1(b) of this Agreement, violate any Law
     or Order applicable to any SFC Company or any of their respective material
     Assets.
 
          (c) Other than in connection or compliance with the provisions of the
     Securities Laws, applicable state corporate and securities Laws, and rules
     of the NASD, and other than Consents required from Regulatory Authorities,
     and other than notices to or filings with the Internal Revenue Service or
     the Pension Benefit Guaranty Corporation with respect to any employee
     benefit plans, or under the HSR Act, and other than Consents, filings, or
     notifications which, if not obtained or made, are not reasonably likely to
     have, individually or in the aggregate, a Material Adverse Effect on SFC,
     no notice to, filing with, or Consent of, any public body or authority is
     necessary for the consummation by SFC of the Merger and the other
     transactions contemplated in this Agreement and the Plan of Merger.
 
     5.3  CAPITAL STOCK.
 
          (a) The authorized capital stock of SFC consists of (i) 6,000,000
     shares of SFC Common Stock, of which 1,498,636 shares are issued and
     outstanding (inclusive of restricted shares) as of the date of this
     Agreement (exclusive of treasury shares) and not more than 1,648,882 shares
     will be issued and outstanding at the Effective Time, and (ii) 1,000,000
     shares of preferred stock, $0.01 par value, of which
 
                                       A-9
<PAGE>   75
 
     no shares are, or will be, issued and outstanding as of the date of this
     Agreement or at the Effective Time, respectively. All of the issued and
     outstanding shares of capital stock of SFC are duly and validly issued and
     outstanding and are fully paid and nonassessable under the DGCL. None of
     the outstanding shares of capital stock of SFC has been issued in violation
     of any preemptive rights of the current or past shareholders of SFC. SFC
     has reserved 286,982 shares of SFC Common Stock for issuance under the SFC
     Stock Plans, pursuant to which options to purchase not more than 150,246
     shares of SFC Common Stock are outstanding and 37,345 restricted shares of
     SFC Common Stock are outstanding.
 
          (b) Except as set forth in Section 5.3(a) of this Agreement, or as
     provided in the Stock Option Agreement there are no shares of capital stock
     or other equity securities of SFC outstanding and no outstanding Rights
     relating to the capital stock of SFC.
 
     5.4  SFC SUBSIDIARIES.  SFC has disclosed in Section 5.4 of the SFC
Disclosure Memorandum all of the SFC Subsidiaries that are corporations
(identifying its jurisdiction of incorporation, each jurisdiction in which
character of its Assets or the nature or conduct of its business requires it to
be qualified and/or licensed to transact business, and the number of shares
owned and percentage ownership interest represented by such share ownership) and
all of the SFC Subsidiaries that are general or limited partnerships or other
non-corporate entities (identifying the Law under which such entity is
organized, each jurisdiction in which character of its Assets or the nature or
conduct of its business requires it to be qualified and/or licensed to transact
business, and the amount and nature of the ownership interest therein of all SFC
Companies). SFC or one of its wholly-owned Subsidiaries owns all of the issued
and outstanding shares of capital stock (or other equity interests) of each SFC
Subsidiary. No capital stock (or other equity interest) of any SFC Subsidiary
are or may become required to be issued (other than to another SFC Company) by
reason of any Rights, and there are no Contracts by which any SFC Subsidiary is
bound to issue (other than to another SFC Company) additional shares of its
capital stock (or other equity interests) or Rights or by which any SFC Company
is or may be bound to transfer any shares of the capital stock (or other equity
interests) of any SFC Subsidiary (other than to another SFC Company). There are
no Contracts relating to the rights of any SFC Company to vote or to dispose of
any shares of the capital stock (or other equity interests) of any SFC
Subsidiary. All of the shares of capital stock (or other equity interests) of
each SFC Subsidiary held by a SFC Company are fully paid and nonassessable under
the applicable corporation or similar Law of the jurisdiction in which such
Subsidiary is incorporated or organized and are owned by the SFC Company free
and clear of any Lien. Each SFC Subsidiary is either a bank, a savings
association, partnership, limited liability corporation, or a corporation, and
each such Subsidiary is duly organized, validly existing, and (as to
corporations) in good standing under the Laws of the jurisdiction in which it is
incorporated or organized, and has the corporate power and authority necessary
for it to own, lease, and operate its Assets and to carry on its business as now
conducted. Each SFC Subsidiary is duly qualified or licensed to transact
business as a foreign corporation in good standing in the States of the United
States and foreign jurisdictions where the character of its Assets or the nature
or conduct of its business requires it to be so qualified or licensed, except
for such jurisdictions in which the failure to be so qualified or licensed is
not reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect on SFC. The only SFC Subsidiary that is a depository institution
is 1st Savings Bank. 1st Savings Bank is an "insured institution" as defined in
the Federal Deposit Insurance Act and applicable regulations thereunder, and the
deposits in which are insured by the Savings Association Insurance Fund. The
minute book and other organizational documents for each SFC Subsidiary have been
made available to UPC for its review, and are true and complete as in effect as
of the date of this Agreement and accurately reflect all amendments thereto and
all proceedings of the Board of Directors and shareholders thereof.

     applicable requirements of the Securities Laws and (ii) did not, at the
     time they were filed (or, if amended or superseded by a filing prior to the

     rules and regulations of the SEC with respect thereto, was prepared in
     accordance with GAAP applied on a consistent basis throughout the periods

     statements or, in the case of unaudited interim statements, as permitted by
     Form 10-QSB of the SEC), and fairly presented in all material respects the
     consolidated financial position of SFC and its Subsidiaries as at the
     respective dates and the consolidated results of its operations and cash
     flows for the periods indicated, except that the unaudited interim

     adjustments which were not or are not expected to be material in amount or
     effect.
 
     5.6  ABSENCE OF UNDISCLOSED LIABILITIES.  No SFC Company has any

March 31, 1997, included in the SFC Financial Statements made available prior to
the date of this Agreement or reflected in the notes thereto. No SFC Company has
incurred or paid any Liability since March 31, 1997, except for such Liabilities

the transactions contemplated by this Agreement.
 
     5.7  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since March 31, 1997, except as

     all Tax Returns filed are complete and accurate. All Taxes shown on filed
     Tax Returns have been paid. There is no audit examination, deficiency, or
     refund Litigation with respect to any Taxes, except as reserved against in
     the SFC Financial Statements made available prior to the date of this
     Agreement and except for certain routine state tax matters which, in the
     aggregate, do not exceed $5,000. All Taxes and other Liabilities due with

<PAGE>   77
 
     comply with, all applicable information reporting and Tax withholding
     requirements under federal, state, and local Tax Laws, and such records
     identify with specificity all accounts subject to backup withholding under
     Section 3406 of the Internal Revenue Code.
 
          (f) Except as set forth in Section 5.8 of the SFC Disclosure
     Memorandum, none of the SFC Companies has made any payments, is obligated
     to make any payments, or is a party to any Contract that could obligate it
     to make any payments that would be disallowed as a deduction under Section
     280G or 162(m) of the Internal Revenue Code.
 
          (g) There has not been an ownership change, as defined in Internal
     Revenue Code Section 382(g), of the SFC Companies that occurred during or
     after any Taxable Period in which the Companies incurred a net operating
     loss that carries over to any Taxable Period ending after December 31,
     1996.
 
          (h) Except as set forth in Section 5.8 of the SFC Disclosure
     Memorandum, none of the SFC Companies is a party to any tax allocation or
     sharing agreement and none of the SFC Companies has been a member of an
     affiliated group filing a consolidated federal income tax return (other
     than a group the common parent of which was SFC) has any Liability for
     taxes of any Person (other than SFC and its Subsidiaries) under Treasury
     Regulation Section 1.1502-6 (or any similar provision of state, local, or
     foreign law) as a transferee or successor or by Contract or otherwise.
 
     5.9  ALLOWANCE FOR POSSIBLE LOAN LOSSES.  The allowance for possible loan
or credit losses (the "Allowance") shown on the consolidated balance sheets of
SFC included in the most recent SFC Financial Statements dated prior to the date
of this Agreement was, and the Allowance shown on the consolidated balance
sheets of SFC included in the SFC Financial Statements as of dates subsequent to
the execution of this Agreement will be, as of the dates thereof, in the
reasonable opinion of management of SFC adequate (within the meaning of GAAP and
applicable regulatory requirements or guidelines) to provide for all known and
reasonably anticipated losses relating to or inherent in the loan and lease
portfolios (including accrued interest receivables) of the SFC Companies and
other extensions of credit (including letters of credit and commitments to make
loans or extend credit) by the SFC Companies as of the dates thereof.
 
     5.10  ASSETS.  Except as set forth in Section 5.10 of the SFC Disclosure
Memorandum or as disclosed or reserved against in the SFC Financial Statements
made available prior to the date of this Agreement, the SFC Companies have good
and marketable title, free and clear of all material Liens, to all of their
respective Assets. All tangible properties used in the businesses of the SFC
Companies are in good condition, reasonable wear and tear excepted, and are
usable in the ordinary course of business consistent with SFC's past practices.
All Assets which are material to SFC's business on a consolidated basis, held
under leases or subleases by any of the SFC Companies, are held under valid
Contracts enforceable in accordance with their respective terms (except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, or other Laws affecting the enforcement of
creditors' rights generally and except that the availability of the equitable
remedy of specific performance or injunctive relief is subject to the discretion
of the court before which any proceedings may be brought), and each such
Contract is in full force and effect. To the Knowledge of SFC, the SFC Companies
currently maintain insurance similar in amounts, scope, and coverage to that
maintained by other peer banking organizations. None of the SFC Companies has
received notice from any insurance carrier that (i) such insurance will be
canceled or that coverage thereunder will be reduced or eliminated, or (ii)
premium costs with respect to such policies of insurance will be substantially
increased. There are presently no claims pending under any such policies of
insurance and no notices have been given by any SFC Company under such policies,
except for routine claims, none of which is material.
 
     5.11  INTELLECTUAL PROPERTY.  All of the Intellectual Property rights of
the SFC Companies are in full force and effect and constitute legal, valid, and
binding obligations of the respective parties thereto, and there have not been,
and, to the Knowledge of SFC, there currently are not, any Defaults thereunder
by SFC. A SFC Company owns or is the valid licensee of all such Intellectual
Property rights free and clear of all Liens or claims of infringement. None of
the SFC Companies or, to the Knowledge of SFC, their respective predecessors has
misused the Intellectual Property rights of others and, to the Knowledge of SFC,
none of the Intellectual Property rights as used in the business conducted by
any such SFC Company infringes upon or otherwise violates the rights of any
Person, nor has any Person asserted a claim of such infringement. To the
 
                                      A-12
<PAGE>   78
 
Knowledge of SFC, no SFC Company is obligated to pay any royalties to any Person
with respect to any such Intellectual Property. To the Knowledge of SFC, each
SFC Company owns or has the valid right to use all of the Intellectual Property
rights which it is presently using, or in connection with performance of any
material Contract to which it is a party. No officer, director, or employee of
any SFC Company is party to any Contract which requires such officer, director
or employee to assign any interest in any Intellectual Property or keep
confidential any trade secrets, proprietary data, customer information, or other
business information, which restricts or prohibits such officer, director, or
employee from engaging in activities competitive with any Person, including any
SFC Company.
 
     5.12  ENVIRONMENTAL MATTERS.
 
          (a) To the Knowledge of SFC, each SFC Company, its Participation
     Facilities, and its Operating Properties are, and have been, in compliance
     with all Environmental Laws, except for violations which are not reasonably
     likely to have, individually or in the aggregate, a Material Adverse Effect
     on SFC.
 
          (b) To the Knowledge of SFC, there is no Litigation pending or
     threatened before any court, governmental agency, or authority or other
     forum in which any SFC Company or any of its Operating Properties or
     Participation Facilities (or SFC in respect of such Operating Property or
     Participation Facility) has been or, with respect to threatened Litigation,
     may be named as a defendant (i) for alleged noncompliance (including by any
     predecessor) with any Environmental Law or (ii) relating to the release
     into the environment of any Hazardous Material, whether or not occurring
     at, on, under, adjacent to, or affecting (or potentially affecting) a site
     owned, leased, or operated by any SFC Company or any of its Operating
     Properties or Participation Facilities, except for such Litigation pending
     or threatened that is not reasonably likely to have, individually or in the
     aggregate, a Material Adverse Effect on SFC, nor is there any reasonable
     basis for any Litigation of a type described in this sentence.
 
          (c) During the period of (i) any SFC Company's ownership or operation
     of any of their respective current properties, (ii) any SFC Company's
     participation in the management of any Participation Facility, or (iii) any
     SFC Company's holding of a security interest in a Operating Property, to
     the Knowledge of SFC, there have been no releases of Hazardous Material in,
     on, under, adjacent to, or affecting (or potentially affecting) such
     properties, except such as are not reasonably likely to have, individually
     or in the aggregate, a Material Adverse Effect on SFC. Prior to the period
     of (i) any SFC Company's ownership or operation of any of their respective
     current properties, (ii) any SFC Company's participation in the management
     of any Participation Facility, or (iii) any SFC Company's holding of a
     security interest in a Operating Property, to the Knowledge of SFC, there
     were no releases of Hazardous Material in, on, under, or affecting any such
     property, Participation Facility or Operating Property, except such as are
     not reasonably likely to have, individually or in the aggregate, a Material
     Adverse Effect on SFC.
 
     5.13  COMPLIANCE WITH LAWS.  SFC is duly registered as a savings and loan
holding company under the HOLA. Each SFC Company has in effect all Permits
necessary for it to own, lease, or operate its material Assets and to carry on
its business as now conducted, and there has occurred no Default under any such
Permit. None of the SFC Companies:
 
          (a) to the Knowledge of SFC, is in violation of any material Laws,
     Orders, or Permits applicable to its business or employees conducting its
     business; and
 
          (b) has received any notification or communication from any agency or
     department of federal, state, or local government or any Regulatory
     Authority or the staff thereof (i) asserting that any SFC Company is not in
     compliance with any of the Laws or Orders which such governmental authority
     or Regulatory Authority enforces, (ii) threatening to revoke any Permits,
     or (iii) requiring any SFC Company to enter into or consent to the issuance
     of a cease and desist order, formal agreement, directive, commitment, or
     memorandum of understanding, or to adopt any Board resolution or similar
     undertaking, which restricts materially the conduct of its business, or in
     any manner relates to its capital adequacy, its credit or reserve policies,
     its management, or the payment of dividends.

<PAGE>   79
 
     5.14  LABOR RELATIONS.  No SFC Company is the subject of any Litigation
asserting that it or any other SFC Company has committed an unfair labor
practice (within the meaning of the National Labor Relations Act or comparable
state law) or seeking to compel it or any other SFC Company to bargain with any
labor organization as to wages or conditions of employment, nor is there any
strike or other labor dispute involving any SFC Company, pending or threatened,
or to the Knowledge of SFC, is there any activity involving any SFC Company's
employees seeking to certify a collective bargaining unit or engaging in any
other organization activity.
 
     5.15  EMPLOYEE BENEFIT PLANS.
 
          (a) SFC has disclosed in Section 5.15 of the SFC Disclosure
     Memorandum, and has delivered or made available to UPC prior to the
     execution of this Agreement copies in each case of, all pension,
     retirement, profit-sharing, deferred compensation, stock option, employee
     stock ownership, severance pay, vacation, bonus, or other incentive plan,
     all other written employee programs, arrangements, or agreements, all
     medical, vision, dental, or other health plans, all life insurance plans,
     and all other employee benefit plans or fringe benefit plans, including
     "employee benefit plans" as that term is defined in Section 3(3) of ERISA,
     currently adopted, maintained by, sponsored in whole or in part by, or
     contributed to by any SFC Company or ERISA Affiliate thereof for the
     benefit of employees, retirees, dependents, spouses, directors, independent
     contractors, or other beneficiaries and under which employees, retirees,
     dependents, spouses, directors, independent contractors, or other
     beneficiaries are eligible to participate (collectively, the "SFC Benefit
     Plans"). Any of the SFC Benefit Plans which is an "employee pension benefit
     plan," as that term is defined in Section 3(2) of ERISA, is referred to
     herein as a "SFC ERISA Plan." Each SFC ERISA Plan which is also a "defined
     benefit plan" (as defined in Section 414(j) of the Internal Revenue Code)
     is referred to herein as a "SFC Pension Plan." Except for the Financial
     Institutions Retirement Fund plan, no SFC Pension Plan is or has been a
     multiemployer plan within the meaning of Section 3(37) of ERISA.
 
          (b) All SFC Benefit Plans are in compliance with the applicable terms
     of ERISA, the Internal Revenue Code, and any other applicable Laws the
     breach or violation of which are reasonably likely to have, individually or
     in the aggregate, a Material Adverse Effect on SFC. Each SFC ERISA Plan
     which is intended to be qualified under Section 401(a) of the Internal
     Revenue Code has received a favorable determination letter from the
     Internal Revenue Service, and SFC is not aware of any circumstances likely
     to result in revocation of any such favorable determination letter. No SFC
     Company has engaged in a transaction with respect to any SFC Benefit Plan
     that, assuming the taxable period of such transaction expired as of the
     date hereof, would subject any SFC Company to a Tax imposed by either
     Section 4975 of the Internal Revenue Code or Section 502(i) of ERISA.
 
          (c) No SFC Pension Plan has any "unfunded current liability," as that
     term is defined in Section 302(d)(8)(A) of ERISA, and the fair market value
     of the assets of any such plan equals or exceeds the plan's "benefit
     liabilities," as that term is defined in Section 4001(a)(16) of ERISA, when
     determined under actuarial factors that would apply if the plan terminated
     in accordance with all applicable legal requirements. Since the date of the
     most recent actuarial valuation, there has been (i) no material change in
     the financial position of any SFC Pension Plan, (ii) no change in the
     actuarial assumptions with respect to any SFC Pension Plan, and (iii) no
     increase in benefits under any SFC Pension Plan as a result of plan
     amendments or changes in applicable Law which is reasonably likely to have,
     individually or in the aggregate, a Material Adverse Effect on SFC or
     materially adversely affect the funding status of any such plan. Neither
     any SFC Pension Plan nor any "single-employer plan," within the meaning of
     Section 4001(a)(15) of ERISA, currently or formerly maintained by any SFC
     Company, or the single-employer plan of any entity which is considered one
     employer with SFC under Section 4001 of ERISA or Section 414 of the
     Internal Revenue Code or Section 302 of ERISA (whether or not waived) (an
     "ERISA Affiliate") has an "accumulated funding deficiency" within the
     meaning of Section 412 of the Internal Revenue Code or Section 302 of
     ERISA. No SFC Company has provided, or is required to provide, security to
     a SFC Pension Plan or to any single-employer plan of an ERISA Affiliate
     pursuant to Section 401(a)(29) of the Internal Revenue Code.
 
                                      A-14
<PAGE>   80
 
          (d) Within the six-year period preceding the Effective Time, no
     Liability under Subtitle C or D of Title IV of ERISA has been or is
     expected to be incurred by any SFC Company with respect to any ongoing,
     frozen, or terminated single-employer plan or the single-employer plan of
     any ERISA Affiliate. No SFC Company has incurred any withdrawal Liability
     with respect to a multiemployer plan under Subtitle B of Title IV of ERISA
     (regardless of whether based on contributions of an ERISA Affiliate). No
     notice of a "reportable event," within the meaning of Section 4043 of ERISA
     for which the 30-day reporting requirement has not been waived, has been
     required to be filed for any SFC Pension Plan or by any ERISA Affiliate
     within the 12-month period ending on the date hereof.
 
          (e) No SFC Company has any Liability for retiree health and life
     benefits under any of the SFC Benefit Plans and there are no restrictions
     on the rights of such SFC Company to amend or terminate any such retiree
     health or benefit Plan without incurring Liability thereunder.
 
          (f) Except as disclosed in Section 5.15 of the SFC Disclosure
     Memorandum, neither the execution and delivery of this Agreement nor the
     consummation of the transactions contemplated hereby will (i) result in any
     payment (including severance, unemployment compensation, golden parachute,
     or otherwise) becoming due to any director or any employee of any SFC
     Company from any SFC Company under any SFC Benefit Plan or otherwise, (ii)
     increase any benefits otherwise payable under any SFC Benefit Plan, or
     (iii) result in any acceleration of the time of payment or vesting of any
     such benefit.
 
          (g) The actuarial present values of all accrued deferred compensation
     entitlements (including entitlements under any executive compensation,
     supplemental retirement, or employment agreement) of employees and former
     employees of any SFC Company and their respective beneficiaries, other than
     entitlements accrued pursuant to funded retirement plans subject to the
     provisions of Section 412 of the Internal Revenue Code or Section 302 of
     ERISA, have been fully reflected on the SFC Financial Statements to the
     extent required by and in accordance with GAAP.
 
     5.16  MATERIAL CONTRACTS.  Except as disclosed in the SFC SEC Reports or as
disclosed in Section 5.16 of the SFC Disclosure Memorandum, none of the SFC
Companies, nor any of their respective Assets, businesses, or operations, is a
party to, or is bound or affected by, or receives benefits under, (i) any
employment, severance, termination, consulting, or retirement Contract providing
for aggregate payments to any Person in any calendar year in excess of $50,000,
(ii) any Contract relating to the borrowing of money by any SFC Company or the
guarantee by any SFC Company of any such obligation (other than Contracts
evidencing deposit liabilities, purchases of federal funds, fully-secured
repurchase agreements, and Federal Home Loan Bank advances of depository
institution Subsidiaries, trade payables, and Contracts relating to borrowings
or guarantees made in the ordinary course of business), (iii) any Contracts
which prohibit or restrict any SFC Company from engaging in any business
activities in any geographic area, line of business, or otherwise in competition
with any other Person, (iv) any Contracts between or among SFC Companies, (v)
any exchange-traded or over-the-counter swap, forward, future, option, cap,
floor, or collar financial Contract, or any other interest rate or foreign
currency protection Contract (not disclosed in the SFC Financial Statements
delivered prior to the date of this Agreement) which is a financial derivative
Contract (including various combinations thereof), and (vi) any other Contract
or amendment thereto that would be required to be filed as an exhibit to a SFC
SEC Report filed by SFC with the SEC prior to the date of this Agreement that
has not been filed as an exhibit to a SFC SEC Report (together with all
Contracts referred to in Sections 5.10 and 5.15(a) of this Agreement, the "SFC
Contracts"). With respect to each SFC Contract: (i) the Contract is in full
force and effect; (ii) no SFC Company is in Default thereunder; (iii) no SFC
Company has repudiated or waived any material provision of any such Contract;
and (iv) no other party to any such Contract is, to the Knowledge of SFC, in
Default in any respect or has repudiated or waived any material provision
thereunder. Except as set forth in Section 5.16 of the SFC Disclosure
Memorandum, all of the indebtedness of any SFC Company for money borrowed is
prepayable at any time by such SFC Company without penalty or premium.
 
     5.17  LEGAL PROCEEDINGS.  There is no Litigation instituted or pending, or,
to the Knowledge of SFC, threatened (or unasserted but considered probable of
assertion and which if asserted would have at least a reasonable probability of
an unfavorable outcome) against any SFC Company, or against any Asset, employee
 
                                      A-15
<PAGE>   81
 
benefit plan, interest, or right of any of them, that is reasonably likely to
have, individually or in the aggregate, a Material Adverse Effect on SFC, nor
are there any Orders of any Regulatory Authorities, other governmental
authorities, or arbitrators outstanding against any SFC Company. Section 5.17 of
the SFC Disclosure Memorandum includes a summary report of all material
Litigation as of the date of this Agreement to which any SFC Company is a party
and which names a SFC Company as a defendant or cross-defendant.
 
     5.18  REPORTS.  Since January 1, 1994, or the date of organization if
later, each SFC Company has timely filed all reports and statements, together

SFC). As of their respective dates, or as subsequently amended for minor
corrections, each of such reports and documents, including the financial
statements, exhibits, and schedules thereto, complied in all material respects
with all applicable Laws. As of its respective date, each such report and
document did not, in all material respects, contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or

under which they were made, not misleading.
 
     5.19  STATEMENTS TRUE AND CORRECT.  No statement, certificate, instrument,
or other writing furnished or to be furnished by any SFC Company or any

agreement, or instrument referred to herein contains or will contain any untrue

make the statements therein, in light of the circumstances under which they were
made, not misleading. None of the information supplied or to be supplied by any
SFC Company or any Affiliate thereof for inclusion in the Registration Statement

effective, be false or misleading with respect to any material fact, or omit to
state any material fact necessary to make the statements therein not misleading.
None of the information supplied or to be supplied by any SFC Company or any
Affiliate thereof for inclusion in the Proxy Statement to be mailed to SFC's
shareholders in connection with the Shareholders' Meeting, and any other
documents to be filed by a SFC Company or any Affiliate thereof with the SEC or
any other Regulatory Authority in connection with the transactions contemplated
hereby, will, at the respective time such documents are filed, and with respect
to the Proxy Statement, when first mailed to the shareholders of SFC, be false
or misleading with respect to any material fact, or omit to state any material
fact necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading, or, in the case of the Proxy
Statement or any amendment thereof or supplement thereto, at the time of the
Shareholders' Meeting, be false or misleading with respect to any material fact,
or omit to state any material fact necessary to correct any statement in any
earlier communication with respect to the solicitation of any proxy for the
Shareholders' Meeting. All documents that any SFC Company or any Affiliate
thereof is responsible for filing with any Regulatory Authority in connection
with the transactions contemplated hereby will comply as to form in all material
respects with the provisions of applicable Law.
 
     5.20  TAX AND REGULATORY MATTERS.  No SFC Company or any Affiliate thereof
has taken any action or has any Knowledge of any fact or circumstance relating
to SFC that is reasonably likely to (i) prevent the transactions contemplated
hereby, including the Merger, from qualifying as a reorganization within the
meaning of Section 368(a) of the Internal Revenue Code, or (ii) materially
impede or delay receipt of any Consents of Regulatory Authorities referred to in
Section 9.1(b) of this Agreement or result in the imposition of a condition or
restriction of the type referred to in the last sentence of such section.
 
     5.21  STATE TAKEOVER LAWS.  Each SFC Company has taken all necessary action
to exempt the transactions contemplated by this Agreement and the Plan of Merger
from, or if necessary challenge the validity or applicability of, any applicable
"moratorium," "fair price," "business combination," "control share," or other
anti-takeover Laws (collectively, "Takeover Laws"), including Section 203 of the
DGCL.
 
     5.22  CHARTER PROVISIONS.  Except as set forth in Section 5.22 of the SFC

entering into of this Agreement and the Plan of Merger
 
                                      A-16
<PAGE>   82
 
and the consummation of the Merger and the other transactions contemplated by
this Agreement and the Plan of Merger do not and will not result in the grant of
any rights to any Person under the Charter, By-laws or other governing
instruments of any SFC Company or restrict or impair the ability of UPC or any
of its Subsidiaries to vote, or otherwise to exercise the rights of a
shareholder with respect to, shares of any SFC Company that may be directly or
indirectly acquired or controlled by it.
 
                                   ARTICLE 6
                     REPRESENTATIONS AND WARRANTIES OF UPC
 
     Except as disclosed in the UPC Disclosure Memorandum, UPC hereby represents
and warrants to SFC as follows:
 
     6.1  ORGANIZATION, STANDING, AND POWER.  UPC is a corporation duly
organized, validly existing, and in good standing under the Laws of the State of
Tennessee, and has the corporate power and authority to carry on its business as
now conducted and to own, lease and operate its material Assets. UPC is duly
qualified or licensed to transact business as a foreign corporation in good
standing in the States of the United States and foreign jurisdictions where the
character of its Assets or the nature or conduct of its business requires it to
be so qualified or licensed, except for such jurisdictions in which the failure
to be so qualified or licensed is not reasonably likely to have, individually or
in the aggregate, a Material Adverse Effect on UPC.
 
     6.2  AUTHORITY; NO BREACH BY AGREEMENT.
 
          (a) UPC has the corporate power and authority necessary to execute,
     deliver and perform its obligations under this Agreement and to consummate
     the transactions contemplated hereby. The execution, delivery and
     performance of this Agreement and the consummation of the transactions
     contemplated herein, including the Merger, have been duly and validly
     authorized by all necessary corporate action in respect thereof on the part
     of UPC. This Agreement (which for purposes of this sentence shall not
     include the Stock Option Agreement) represents a legal, valid, and binding
     obligation of UPC, enforceable against UPC in accordance with its terms
     (except in all cases as such enforceability may be limited by applicable
     bankruptcy, insolvency, reorganization, moratorium, or similar Laws
     affecting the enforcement of creditors' rights generally and except that
     the availability of the equitable remedy of specific performance or
     injunctive relief is subject to the discretion of the court before which
     any proceeding may be brought).
 
          (b) Neither the execution and delivery of this Agreement by UPC, nor
     the consummation by UPC of the transactions contemplated hereby, nor
     compliance by UPC with any of the provisions hereof, will (i) conflict with
     or result in a breach of any provision of UPC's Restated Charter of
     Incorporation or By-laws, or (ii) constitute or result in a Default under,
     or require any Consent pursuant to, or result in the creation of any Lien
     on any Asset of any UPC Company under, any Contract or Permit of any UPC
     Company, or (iii) subject to receipt of the requisite approvals referred to
     in Section 9.1(b) of this Agreement, violate any Law or Order applicable to
     any UPC Company or any of their respective material Assets.
 
          (c) Other than in connection or compliance with the provisions of the
     Securities Laws, applicable state corporate and securities Laws, and rules
     of the NYSE, and other than Consents required from Regulatory Authorities,
     and other than notices to or filings with the Internal Revenue Service or
     the Pension Benefit Guaranty Corporation with respect to any employee
     benefit plans, or under the HSR Act, and other than Consents, filings, or
     notifications which, if not obtained or made, are not reasonably likely to
     have, individually or in the aggregate, a Material Adverse Effect on UPC,
     no notice to, filing with, or Consent of, any public body or authority is
     necessary for the consummation by UPC or UPC Merger Subsidiary of the
     Merger and the other transactions contemplated in this Agreement and the
     Plan of Merger.
 
     6.3  CAPITAL STOCK.  The authorized capital stock of UPC consists of (i)
100,000,000 shares of UPC Common Stock, of which 66,010,936 shares were issued
and outstanding as of March 31, 1997 (exclusive of treasury shares), and (ii)
10,000,000 shares of UPC Preferred Stock, of which no shares of UPC Series A
 
                                      A-17
<PAGE>   83
 
Preferred Stock, and 2,877,474 shares of UPC Series E Preferred Stock, are
issued and outstanding. All of the issued and outstanding shares of UPC Capital
Stock are, and all of the shares of UPC Common Stock to be issued in exchange
for shares of SFC Common Stock upon consummation of the Merger, when issued in
accordance with the terms of this Agreement, will be, duly and validly issued
and outstanding and fully paid and nonassessable under the Tennessee Business
Corporation Act. None of the outstanding shares of UPC Capital Stock has been,
and none of the shares of UPC Common Stock to be issued in exchange for shares
of SFC Common Stock upon consummation of the Merger will be, issued in violation
of any preemptive rights of the current or past shareholders of UPC. UPC has
reserved for issuance a sufficient number of shares of UPC Common Stock for the
purpose of issuing shares of UPC Common Stock in accordance with the provisions
of Sections 3.1 and 3.5 of this Agreement.
 
     6.4  UPC SUBSIDIARIES.  UPC or one of its Subsidiaries owns all of the
issued and outstanding shares of capital stock of each UPC Subsidiary. No equity
securities of any UPC Subsidiary are or may become required to be issued (other
than to another UPC Company) by reason of any Rights, and there are no Contracts
by which any UPC Subsidiary is bound to issue (other than to another UPC
Company) additional shares of its capital stock or Rights or by which any UPC
Company is or may be bound to transfer any shares of the capital stock of any
UPC Subsidiary (other than to another UPC Company). There are no Contracts
relating to the rights of any UPC Company to vote or to dispose of any shares of
the capital stock of any UPC Subsidiary. All of the shares of capital stock of
each UPC Subsidiary held by a UPC Company are fully paid and nonassessable
(except pursuant to 12 USC Section 55 in the case of national banks and
comparable, applicable state Law, if any, in the case of state depository
institutions) under the applicable corporation Law of the jurisdiction in which
such Subsidiary is incorporated or organized and are owned by the UPC Company
free and clear of any Lien. Each UPC Subsidiary is either a bank or a
corporation, and is duly organized, validly existing, and (as to corporations)
in good standing under the Laws of the jurisdiction in which it is incorporated
or organized, and has the corporate power and authority necessary for it to own,
lease, and operate its Assets and to carry on its business as now conducted.
Each UPC Subsidiary is duly qualified or licensed to transact business as a
foreign corporation in good standing in the States of the United States and
foreign jurisdictions where the character of its Assets or the nature or conduct
of its business requires it to be so qualified or licensed, except for such
jurisdictions in which the failure to be so qualified or licensed is not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on UPC. Each UPC Subsidiary that is a depository institution is an
"insured institution" as defined in the Federal Deposit Insurance Act and
applicable regulations thereunder, and the deposits in which are insured by the
Bank Insurance Fund or Savings Association Insurance Fund.
 
     6.5  SEC FILINGS; FINANCIAL STATEMENTS.
 
          (a) UPC has filed and made available to SFC all SEC Documents required
     to be filed by UPC since December 31, 1993 (the "UPC SEC Reports"). The UPC
     SEC Reports (i) at the time filed, complied in all material respects with
     the applicable requirements of the Securities Laws and (ii) did not, at the
     time they were filed (or, if amended or superseded by a filing prior to the
     date of this Agreement, then on the date of such filing) contain any untrue
     statement of a material fact or omit to state a material fact required to
     be stated in such UPC SEC Reports or necessary in order to make the
     statements in such UPC SEC Reports, in light of the circumstances under
     which they were made, not misleading. Except for UPC Subsidiaries that are
     registered as a broker, dealer, or investment advisor, none of UPC's
     Subsidiaries is required to file any SEC Documents.
 
          (b) Each of the UPC Financial Statements (including, in each case, any
     related notes) contained in the UPC SEC Reports, including any UPC SEC
     Reports filed after the date of this Agreement until the Effective Time,
     complied as to form in all material respects with the applicable published
     rules and regulations of the SEC with respect thereto, was prepared in
     accordance with GAAP applied on a consistent basis throughout the periods
     involved (except as may be indicated in the notes to such financial
     statements or, in the case of unaudited interim statements, as permitted by
     Form 10-Q of the SEC), and fairly presented in all material respects the
     consolidated financial position of UPC and its Subsidiaries as at the
     respective dates and the consolidated results of its operations and cash
     flows for the periods
 
                                      A-18
<PAGE>   84
 
     indicated, except that the unaudited interim financial statements were or
     are subject to normal and recurring year-end adjustments which were not or
     are not expected to be material in amount or effect.
 
     6.6  ABSENCE OF UNDISCLOSED LIABILITIES.  No UPC Company has any
Liabilities that are reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on UPC, except Liabilities which are
accrued or reserved against in the consolidated balance sheets of UPC as of
March 31, 1997, included in the UPC Financial Statements made available prior to
the date of this Agreement or reflected in the notes thereto. No UPC Company has
incurred or paid any Liability since March 31, 1997, except for such Liabilities
incurred or paid (i) in the ordinary course of business consistent with past
business practice and which are not reasonably likely to have, individually or
in the aggregate, a Material Adverse Effect on UPC or (ii) in connection with
the transactions contemplated by this Agreement.
 
     6.7  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since March 31, 1997, except as
disclosed in the UPC Financial Statements made available prior to the date of
this Agreement or contemplated by pending federal legislation applicable to
financial institutions generally, (i) there have been no events, changes, or
occurrences which have had, or are reasonably likely to have, individually or in
the aggregate, a Material Adverse Effect on UPC, and (ii) the UPC Companies have
not taken any action, or failed to take any action, prior to the date of this
Agreement, which action or failure, if taken after the date of this Agreement,
would represent or result in a material breach or violation of any of the
covenants and agreements of UPC contained in this Agreement.
 
     6.8  TAX MATTERS.
 
          (a) All Tax Returns required to be filed by or on behalf of any of the
     UPC Companies have been timely filed or requests for extensions have been
     timely filed, granted, and have not expired for periods ended on or before
     December 31, 1996, and on or before the date of the most recent fiscal year
     end immediately preceding the Effective Time, and, to the Knowledge of UPC,
     all Tax Returns filed are complete and accurate. All Taxes shown on filed
     Tax Returns have been paid. There is no audit examination, deficiency, or
     refund Litigation with respect to any Taxes, except as reserved against in
     the UPC Financial Statements delivered prior to the date of this Agreement.
     All Taxes and other Liabilities due with respect to completed and settled
     examinations or concluded Litigation have been paid. There are no Liens
     with respect to Taxes upon any of the Assets of the UPC Companies.
 
          (b) Adequate provision for any Taxes due or to become due for any of
     the UPC Companies for the period or periods through and including the date
     of the respective UPC Financial Statements has been made and is reflected
     on such UPC Financial Statements.
 
          (c) Deferred Taxes of the UPC Companies have been provided for in
     accordance with GAAP.
 
     6.9  ENVIRONMENTAL MATTERS.
 
          (a) To the Knowledge of UPC, each UPC Company, its Participation
     Facilities, and its Operating Properties are, and have been, in compliance
     with all Environmental Laws, except for violations which are not reasonably
     likely to have, individually or in the aggregate, a Material Adverse Effect
     on UPC.
 
          (b) To the Knowledge of UPC, there is no Litigation pending or
     threatened before any court, governmental agency, or authority or other
     forum in which any UPC Company or any of its Operating Properties or
     Participation Facilities (or UPC in respect of such Operating Property or
     Participation Facility) has been or, with respect to threatened Litigation,
     may be named as a defendant (i) for alleged noncompliance (including by any
     predecessor) with any Environmental Law or (ii) relating to the release
     into the environment of any Hazardous Material, whether or not occurring
     at, on, under, adjacent to, or affecting (or potentially affecting) a site
     owned, leased, or operated by any UPC Company or any of its Operating
     Properties or Participation Facilities, except for such Litigation pending
     or threatened that is not reasonably likely to have, individually or in the
     aggregate, a Material Adverse Effect on UPC, nor is there any reasonable
     basis for any Litigation of a type described in this sentence.
 
          (c) During the period of (i) any UPC Company's ownership or operation
     of any of their respective current properties, (ii) any UPC Company's
     participation in the management of any Participation Facility, or (iii) any
     UPC Company's holding of a security interest in a Operating Property, to
     the
 
                                      A-19
<PAGE>   85
 
     Knowledge of UPC, there have been no releases of Hazardous Material in, on,
     under, adjacent to, or affecting (or potentially affecting) such
     properties, except such as are not reasonably likely to have, individually
     or in the aggregate, a Material Adverse Effect on UPC. Prior to the period
     of (i) any UPC Company's ownership or operation of any of their respective
     current properties, (ii) any UPC Company's participation in the management
     of any Participation Facility, or (iii) any UPC Company's holding of a
     security interest in a Operating Property, to the Knowledge of UPC, there
     were no releases of Hazardous Material in, on, under, or affecting any such
     property, Participation Facility or Operating Property, except such as are
     not reasonably likely to have, individually or in the aggregate, a Material
     Adverse Effect on UPC.
 
     6.10  COMPLIANCE WITH LAWS.  UPC is duly registered as a bank holding
company under the BHC Act and as a savings and loan holding company under the
HOLA. Each UPC Company has in effect all Permits necessary for it to own, lease,
or operate its material Assets and to carry on its business as now conducted,
and there has occurred no Default under any such Permit. No UPC Company:
 
          (a) to the Knowledge of UPC, is in violation of any material Laws,
     Orders, or Permits applicable to its business or employees conducting its
     business; and
 
          (b) has received any notification or communication from any agency or
     department of federal, state, or local government or any Regulatory
     Authority or the staff thereof (i) asserting that any UPC Company is not in
     compliance with any of the Laws or Orders which such governmental authority
     or Regulatory Authority enforces, (ii) threatening to revoke any Permits,
     or (iii) requiring any UPC Company to enter into or consent to the issuance
     of a cease and desist order, formal agreement, directive, commitment or
     memorandum of understanding, or to adopt any Board resolution or similar
     undertaking, which restricts materially the conduct of its business, or in
     any manner relates to its capital adequacy, its credit or reserve policies,
     its management, or the payment of dividends.
 
     6.11  LEGAL PROCEEDINGS.  There is no Litigation instituted or pending, or,
to the Knowledge of UPC, threatened (or unasserted but considered probable of
assertion and which if asserted would have at least a reasonable probability of
an unfavorable outcome) against any UPC Company, or against any Asset, employee
benefit plan, interest, or right of any of them, that is reasonably likely to
have, individually or in the aggregate, a Material Adverse Effect on UPC, nor
are there any Orders of any Regulatory Authorities, other governmental
authorities, or arbitrators outstanding against any UPC Company.
 
     6.12  REPORTS.  Since January 1, 1994, or the date of organization if
later, each UPC Company has filed all reports and statements, together with any
amendments required to be made with respect thereto, that it was required to
file with (i) the SEC, including, but not limited to, Forms 10-K, Forms 10-Q,
Forms 8-K, and proxy statements, (ii) other Regulatory Authorities, and (iii)
any applicable state securities or banking authorities (except, in the case of
state securities authorities, failures to file which are not reasonably likely
to have, individually or in the aggregate, a Material Adverse Effect on UPC). As
of their respective dates, each of such reports and documents, including the
financial statements, exhibits, and schedules thereto, complied in all material
respects with all applicable Laws. As of its respective date, each such report
and document did not, in all material respects, contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements made therein, in light of the circumstances
under which they were made, not misleading.
 
     6.13  STATEMENTS TRUE AND CORRECT.  No statement, certificate, instrument
or other writing furnished or to be furnished by any UPC Company or any
Affiliate thereof to SFC pursuant to this Agreement or any other document,
agreement, or instrument referred to herein contains or will contain any untrue
statement of material fact or will omit to state a material fact necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading. None of the information supplied or to be supplied by any
UPC Company or any Affiliate thereof for inclusion in the Registration Statement
to be filed by UPC with the SEC, will, when the Registration Statement becomes
effective, be false or misleading with respect to any material fact, or omit to
state any material fact necessary to make the statements therein not misleading.
None of the information supplied or to be supplied by any UPC Company or any
Affiliate thereof for inclusion in the Proxy Statement to be mailed to SFC's
shareholders in connection with the Shareholders'

proxy for the Shareholders' Meeting. All documents that any UPC Company or any
Affiliate thereof is responsible for filing with any Regulatory Authority in
connection with the transactions contemplated hereby will comply as to form in
all material respects with the provisions of applicable Law.
 
     6.14  TAX AND REGULATORY MATTERS.  No UPC Company or any Affiliate thereof
has taken any action or has any Knowledge of any fact or circumstance relating
to UPC that is reasonably likely to (i) prevent the transactions contemplated
hereby, including the Merger, from qualifying as a reorganization within the
meaning of Section 368(a) of the Internal Revenue Code, or (ii) materially
impede or delay receipt of any Consents of Regulatory Authorities referred to in
Section 9.1(b) of this Agreement or result in the imposition of a condition or
restriction of the type referred to in the last sentence of such Section.

shall cause each of its Subsidiaries to (i) operate its business only in the
usual, regular, and ordinary course, (ii) preserve intact its business

contemplated hereby, including the Merger, from qualifying as a reorganization

agrees that it shall (i) continue to conduct its business and the business of
its Subsidiaries in a manner designed in its reasonable judgment, to enhance the
long-term value of the UPC Common Stock and the business prospects of the UPC
Companies, and (ii) take no action which would (a) materially adversely affect
the ability of any Party to obtain any Consents required for the transactions
contemplated hereby without imposition of a condition or restriction of the type
referred to in the last sentence of Section 9.1(b) of this Agreement or prevent
the transactions contemplated hereby, including the Merger, from qualifying as a
reorganization within the meaning of Section 368(a) of the Internal Revenue
Code, or (b) materially adversely affect the ability of any Party to perform its
covenants and agreements under this Agreement.
 
     7.4  ADVERSE CHANGES IN CONDITION.  Each Party agrees to give written

contained herein, and to use its reasonable efforts to prevent or promptly to
remedy the same.

changes in shareholders' equity, and cash flows for the periods then ended in
accordance with GAAP (subject in the case of interim financial statements to
normal recurring year-end adjustments that are not material). As of their
respective dates, such reports filed with the SEC will comply in all material
respects with the Securities Laws and will not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading. Any financial statements contained
in any other reports to another Regulatory Authority shall be prepared in
accordance with Laws applicable to such reports.

advisable under applicable Laws to consummate and make effective, as soon as

     cause to be made such investigation of the business and properties of it
     and its Subsidiaries and of their respective financial and legal conditions
     as the other Party reasonably requests, provided that such investigation
     shall be reasonably related to the transactions contemplated hereby and
     shall not interfere unnecessarily with normal operations. No investigation

     8.7  PRESS RELEASES.  Prior to the Effective Time, SFC and UPC shall
consult with each other as to the form and substance of any press release or
other public disclosure materially related to this Agreement or any other
transaction contemplated hereby; provided, that nothing in this Section 8.7
shall be deemed to prohibit any Party from making any disclosure which its
counsel deems necessary or advisable in order to satisfy such Party's disclosure
obligations imposed by Law.
 
     8.8  CERTAIN ACTIONS.  Except with respect to this Agreement and the Plan
of Merger and the transactions contemplated hereby and thereby, after the date
of this Agreement, no SFC Company nor any Affiliate thereof nor any
Representatives thereof retained by any SFC Company shall directly or indirectly
solicit any Acquisition Proposal by any Person. Except to the extent necessary
to comply with the fiduciary duties of SFC's Board of Directors as advised by
counsel, no SFC Company or any Affiliate or Representative thereof shall furnish
any non-public information that it is not legally obligated to furnish,
negotiate with respect to, or enter into any Contract with respect to, any
Acquisition Proposal, but SFC may communicate information about such an
Acquisition Proposal to its shareholders if and to the extent that it is
required to do so in order to comply with its legal obligations as advised by
counsel. SFC shall promptly notify UPC orally and in writing in the event that
it receives any inquiry or proposal relating to any such transaction. SFC shall
(i) immediately cease and cause to be terminated any existing activities,
discussions, or negotiations with any Persons conducted heretofore with respect
to any of the foregoing, and (ii) direct and use its reasonable efforts to cause
all of its Representatives not to engage in any of the foregoing.

     8.10  STATE TAKEOVER LAWS.  Each SFC Company shall take all necessary steps
to exempt the transactions contemplated by this Agreement from, or if necessary
challenge the validity or applicability of, any applicable Takeover Law.
 
     8.11  CHARTER PROVISIONS.  Each SFC Company shall take all necessary action
to ensure that the entering into of this Agreement and the Plan of Merger and
the consummation of the Merger and the other transactions contemplated hereby
and thereby do not and will not result in the grant of any rights to any Person
under the Charter, By-laws, or other governing instruments of any SFC Company or
restrict or impair the ability of UPC or any of its Subsidiaries to vote, or
otherwise to exercise the rights of a shareholder with respect to, shares of any
SFC Company that may be directly or indirectly acquired or controlled by it.
 
     8.12  AGREEMENTS OF AFFILIATES.  SFC has disclosed in Section 8.12 of the
SFC Disclosure Memorandum all Persons whom it reasonably believes is an
"affiliate" of SFC for purposes of Rule 145 under the 1933 Act. SFC shall use
its reasonable efforts to cause each such Person to deliver to UPC not later
than 30 days prior to the Effective Time, a written agreement, substantially in
the form of Exhibit 3, providing that such Person will not sell, pledge,
transfer, or otherwise dispose of the shares of SFC Common Stock held by such
Person except as contemplated by such agreement or by this Agreement and will
not sell, pledge, transfer, or otherwise dispose of the shares of UPC Common
Stock to be received by such Person upon consummation of the Merger except in
compliance with applicable provisions of the 1933 Act and the rules and

Supplemental Letter, following the Effective Time, UPC shall provide to officers
and employees of the SFC Companies employee benefits under employee benefit and

similarly situated officers and employees. For purposes of participation,
vesting, and (except in the case of retirement plans) benefit accrual under such
employee benefit plans, the service of the employees of the SFC Companies prior
to the Effective Time shall be treated as service with a UPC Company
participating in such employee benefit plans.

     8.14  INDEMNIFICATION.
 
          (a) After the Effective Time, UPC shall indemnify, defend and hold
     harmless the present and former directors, officers, employees, and agents
     of the SFC Companies (each, an "Indemnified Party") (including any person
     who becomes a director, officer, employee, or agent prior to the Effective
     Time) against all Liabilities (including reasonable attorneys' fees, and
     expenses, judgments, fines and amounts paid in settlement) arising out of
     actions or omissions occurring at or prior to the Effective Time (including
     the transactions contemplated by this Agreement and the Stock Option
     Agreement) to the full extent permitted under Delaware Law and by SFC's
     Charter and By-laws as in effect on the date hereof, including provisions
     relating to advances of expenses incurred in the defense of any Litigation.
     Without limiting the foregoing, in any case in which approval by UPC is
     required to effectuate any indemnification, UPC shall direct, at the
     election of the Indemnified Party, that the determination of any such
     approval shall be made by independent counsel mutually agreed upon between
     UPC and the Indemnified Party.
 
          (b) Any Indemnified Party wishing to claim indemnification under
     paragraph (a) of this Section 8.14, upon learning of any such Liability or
     Litigation, shall promptly notify UPC thereof, provided that the failure so
     to notify shall not affect the obligations of UPC under this Section 8.14
     unless and to the extent such failure materially increases UPC's liability
     under this Section 8.14. In the event of any such Litigation (whether
     arising before or after the Effective Time), (i) UPC or the Surviving
     Corporation shall have the right to assume the defense thereof and UPC
     shall not be liable to such Indemnified Parties for any legal expenses of
     other counsel or any other expenses subsequently incurred by such
     Indemnified Parties in connection with the defense thereof, except that if
     UPC or the Surviving Corporation elects not to assume such defense or
     counsel for the Indemnified Parties advises that there are substantive
     issues which raise conflicts of interest between UPC or the Surviving
     Corporation and the Indemnified Parties, the Indemnified Parties may retain
     counsel satisfactory to them, and UPC or the Surviving Corporation shall
     pay all reasonable fees and expenses of such counsel for the Indemnified
     Parties promptly as statements therefor are received; provided, that UPC
     shall be obligated pursuant to this paragraph (b) to pay for only one firm
     of counsel for all Indemnified Parties in any jurisdiction, (ii) the
     Indemnified Parties will cooperate in the defense of any such Litigation,
     and (iii) UPC shall not be liable for any settlement effected without its
     prior written consent; and provided further that the Surviving Corporation
     shall not have any obligation hereunder to any Indemnified Party when and
     if a court of competent jurisdiction shall determine, and such
     determination shall have become final, that the indemnification of such
     Indemnified Party in the manner contemplated hereby is prohibited by
     applicable Law.
 
          (c) The Surviving Corporation shall not be liable for any settlement
     effected without its prior written consent which shall not be unreasonably
     withheld. The Surviving Corporation shall not have any obligation hereunder
     to any Indemnified Party when and if a court of competent jurisdiction
     shall determine, and such determination shall have become final, that the
     indemnification of such Indemnified Party in the manner contemplated hereby
     is prohibited by applicable Law.
 
          (d) If the Surviving Corporation or any of its successors or assigns
     shall consolidate with or merge into any other Person and shall not be the
     continuing or surviving Person of such consolidation or merger or shall
     transfer all or substantially all of its assets to any Person, then and in
     each case, proper provision shall be made so that the successors and
     assigns of the Surviving Corporation shall assume the obligations set forth
     in this Section 8.14.
 
     8.15  UPC MERGER SUBSIDIARY ORGANIZATION.  UPC shall organize UPC Merger
Subsidiary under the Laws of the State of Delaware. Prior to the Effective Time,
the outstanding capital stock of UPC Merger Subsidiary shall consist of 1,000
shares of UPC Merger Subsidiary Common Stock, all of which shares shall be owned
by UPC. Prior to the Effective Time, UPC Merger Subsidiary shall not (i) conduct
any business operations whatsoever or (ii) enter into any Contract or agreement
of any kind, acquire any assets or incur any Liability, except as may be
specifically contemplated by this Agreement or the Plan of Merger or as the
 
                                      A-26
<PAGE>   92
 
Parties may otherwise agree. UPC, as the sole stockholder of UPC Merger

of each Party to perform this Agreement and consummate the Merger and the other
transactions contemplated hereby are subject to the satisfaction of the
following conditions, unless waived by both Parties pursuant to Section 11.6 of
this Agreement:
 
          (a) SHAREHOLDER APPROVAL.  The shareholders of SFC shall have approved

     instruments, or by the rules of the NASD.
 
          (b) REGULATORY APPROVALS.  All Consents of, filings and registrations
     with, and notifications to, all Regulatory Authorities required for
     consummation of the Merger shall have been obtained or made and shall be in
     full force and effect and all waiting periods required by Law shall have
     expired. No Consent obtained from any Regulatory Authority which is
     necessary to consummate the transactions contemplated hereby shall be
     conditioned or restricted in a manner (other than matters relating to the
     raising of additional capital or the disposition of Assets (including, but
     not limited to, any divestiture or restrictions on the insurance activities
     of any SFC Companies) or deposit Liabilities and associated branches) which
     in the reasonable judgment of the Board of Directors of UPC would so
     materially adversely impact the financial or economic benefits of the
     transactions contemplated by this Agreement that, had such condition or
     requirement been known, UPC would not, in its reasonable judgment, have
     entered into this Agreement.
 
          (c) CONSENTS AND APPROVALS.  Each Party shall have obtained any and
     all Consents required for consummation of the Merger (other than those
     referred to in Section 9.1(b) of this Agreement) or for the preventing of
     any Default under any Contract or Permit of such Party which, if not
     obtained or made, is reasonably likely to have, individually or in the
     aggregate, a Material Adverse Effect on such Party.
 
          (d) LEGAL PROCEEDINGS.  No court or governmental or regulatory
     authority of competent jurisdiction shall have enacted, issued,
     promulgated, enforced, or entered any Law or Order (whether temporary,
     preliminary, or permanent) or taken any other action which prohibits,
     restricts, or makes illegal consummation of the transactions contemplated
     by this Agreement and the Plan of Merger.
 
          (e) REGISTRATION STATEMENT.  The Registration Statement shall be
     effective under the 1933 Act, no stop orders suspending the effectiveness
     of the Registration Statement shall have been issued, no action, suit,
     proceeding, or investigation by the SEC to suspend the effectiveness
     thereof shall have been initiated and be continuing, and all necessary
     approvals under state securities Laws or the 1933 Act or 1934 Act relating
     to the issuance or trading of the shares of UPC Common Stock issuable
     pursuant to the Merger shall have been received.
 
          (f) EXCHANGE LISTING.  The shares of UPC Common Stock issuable
     pursuant to the Merger shall have been approved for listing on the NYSE,

          (g) TAX MATTERS.  Each Party shall have received a written opinion of
     counsel from Alston & Bird LLP, in form reasonably satisfactory to such
     Parties (the "Tax Opinion"), to the effect that (i) the Merger will
     constitute a reorganization within the meaning of Section 368(a) of the
     Internal Revenue Code, (ii) the exchange in the Merger of SFC Common Stock
     for UPC Common Stock will not give rise to gain or loss to the shareholders
     of SFC with respect to such exchange (except to the extent of any cash
     received), and (iii) none of SFC or UPC will recognize gain or loss as a
     consequence of the Merger (except for the inclusion in income of the amount
     of the bad-debt reserve maintained by 1st Savings Bank and any other
     amounts resulting from any required change in accounting methods and any
     income
 
                                      A-27
<PAGE>   93
 
     and deferred gain recognized pursuant to Treasury regulations issued under
     Section 1502 of the Internal Revenue Code). In rendering such Tax Opinion,
     such counsel shall be entitled to rely upon representations of officers of
     SFC and UPC reasonably satisfactory in form and substance to such counsel.
 
     9.2  CONDITIONS TO OBLIGATIONS OF UPC.  The obligations of UPC to perform
this Agreement and consummate the Merger and the other transactions contemplated
hereby are subject to the satisfaction of the following conditions, unless
waived by UPC pursuant to Section 11.6(a) of this Agreement:
 
          (a) REPRESENTATIONS AND WARRANTIES.  For purposes of this Section
     9.2(a), the accuracy of the representations and warranties of SFC set forth
     in this Agreement shall be assessed as of the date of this Agreement and as
     of the Effective Time with the same effect as though all such
     representations and warranties had been made on and as of the Effective
     Time (provided that representations and warranties which are confined to a
     specified date shall speak only as of such date). The representations and
     warranties of SFC set forth in Section 5.3 of this Agreement shall be true
     and correct (except for inaccuracies which are de minimus in amount). The
     representations and warranties of SFC set forth in Sections 5.20, 5.21, and
     5.22 of this Agreement shall be true and correct in all material respects.
     There shall not exist inaccuracies in the representations and warranties of
     SFC set forth in this Agreement (including the representations and
     warranties set forth in Sections 5.3, 5.20, 5.21, and 5.22) such that the
     aggregate effect of such inaccuracies has, or is reasonably likely to have,
     a Material Adverse Effect on SFC; provided that, for purposes of this
     sentence only, those representations and warranties which are qualified by
     references to "material" or "Material Adverse Effect" shall be deemed not
     to include such qualifications.
 
          (b) PERFORMANCE OF AGREEMENTS AND COVENANTS.  Each and all of the
     agreements and covenants of SFC to be performed and complied with pursuant
     to this Agreement and the other agreements contemplated hereby prior to the
     Effective Time shall have been duly performed and complied with in all
     material respects.
 
          (c) CERTIFICATES.  SFC shall have delivered to UPC (i) a certificate,
     dated as of the Effective Time and signed on its behalf by its chief
     executive officer and its chief financial officer, to the effect that the
     conditions of its obligations set forth in Section 9.2(a) and 9.2(b) of
     this Agreement have been satisfied, and (ii) certified copies of
     resolutions duly adopted by SFC's Board of Directors and shareholders
     evidencing the taking of all corporate action necessary to authorize the
     execution, delivery, and performance of this Agreement and the Plan of
     Merger, and the consummation of the transactions contemplated hereby and
     thereby, all in such reasonable detail as UPC and its counsel shall

     inaccuracies has, or is reasonably likely to have, a Material Adverse
     Effect on UPC; provided that, for

this Agreement and the Plan of Merger may be terminated and the Merger abandoned
at any time prior to the Effective Time:
 
          (a) By mutual consent of the Board of Directors of UPC and the Board
     of Directors of SFC; or
 
          (b) By the Board of Directors of either Party (provided that the
     terminating Party is not then in breach of any representation or warranty
     contained in this Agreement under the applicable standard set forth in
     Section 9.2(a) of this Agreement in the case of SFC and Section 9.3(a) in
     the case of UPC or in material breach of any covenant or other agreement
     contained in this Agreement) in the event of an inaccuracy of any
     representation or warranty of the other Party contained in this Agreement
     which cannot be or has not been cured within 30 days after the giving of
     written notice to the breaching Party of such inaccuracy and which
     inaccuracy would provide the terminating Party the ability to refuse to
     consummate the Merger under the applicable standard set forth in Section
     9.2(a) of this Agreement in the case of SFC and Section 9.3(a) of this
     Agreement in the case of UPC; or

     contained in this Agreement under the applicable standard set forth in
     Section 9.2(a) of this Agreement in the case of SFC and Section 9.3(a) in
     the case of UPC or in material breach of any covenant or other agreement
     contained in this Agreement) in the event of a material breach by the other
     Party of any covenant or agreement contained in this Agreement which cannot
     be or has not been cured within 30 days after the giving of written notice
     to the breaching Party of such breach; or
 
          (d) By the Board of Directors of either Party in the event (i) any
     Consent of any Regulatory Authority required for consummation of the Merger
     and the other transactions contemplated hereby shall have been denied by
     final nonappealable action of such authority or if any action taken by such
     authority is not appealed within the time limit for appeal, or (ii) the
     shareholders of SFC fail to vote their approval of this Agreement and the
     transactions contemplated hereby as required by the DGCL and the rules of
     the NASD at the Shareholders' Meeting where the transactions were presented
     to such shareholders for approval and voted upon; or
 
          (e) By the Board of Directors of either Party in the event that the
     Merger shall not have been consummated by June 30, 1998, if the failure to
     consummate the transactions contemplated hereby on or before such date is
     not caused by any willful breach of this Agreement by the Party electing to
     terminate pursuant to this Section 10.1(e); or
 
                                      A-29
<PAGE>   95
 
          (f) By the Board of Directors of either Party (provided that the
     terminating Party is not then in breach of any representation or warranty
     contained in this Agreement under the applicable standard set forth in
     Section 9.2(a) of this Agreement in the case of SFC and Section 9.3(a) in
     the case of UPC or in material breach of any covenant or other agreement
     contained in this Agreement) in the event that any of the conditions
     precedent to the obligations of such Party to consummate the Merger cannot
     be satisfied or fulfilled by the date specified in Section 10.1(e) of this
     Agreement; or
 
          (g) By the Board of Directors of SFC, if it determines by a vote of a
     majority of the members of its entire Board, at any time during the ten-day
     period commencing two days after the Determination Date, if both of the
     following conditions are satisfied:
 
             (1) the Average Closing Price shall be less than the product of (i)
        0.80 and (ii) the Starting Price; and
 
             (2) (i) the quotient obtained by dividing the Average Closing Price
        by the Starting Price (such number being referred to herein as the "UPC
        Ratio") shall be less than (ii) the quotient obtained by dividing the
        Index Price on the Determination Date by the Index Price on the Starting
        Date and subtracting 0.15 from the quotient in this clause (2)(ii) (such
        number being referred to herein as the "Index Ratio");
 
     subject, however, to the following three sentences. If SFC refuses to
     consummate the Merger pursuant to this Section 10.1(g), it shall give
     prompt written notice thereof to UPC; provided, that such notice of
     election to terminate may be withdrawn at any time within the
     aforementioned ten-day period. During the five-day period commencing with
     its receipt of such notice, UPC shall have the option to elect to increase
     the Exchange Ratio to equal the lesser of (i) the quotient obtained by
     dividing (1) the product of 0.80, the Starting Price, and the Exchange
     Ratio (as then in effect) by (2) the Average Closing Price, and (ii) the
     quotient obtained by dividing (1) the product of the Index Ratio and the
     Exchange Ratio (as then in effect) by (2) the UPC Ratio. If UPC makes an
     election contemplated by the preceding sentence, within such five-day
     period, it shall give prompt written notice to SFC of such election and the
     revised Exchange Ratio, whereupon no termination shall have occurred
     pursuant to this Section 10.1(g) and this Agreement shall remain in effect
     in accordance with its terms (except as the Exchange Ratio shall have been
     so modified), and any references in this Agreement to "Exchange Ratio"
     shall thereafter be deemed to refer to the Exchange Ratio as adjusted
     pursuant to this Section 10.1(g).

        company to be acquired or for such company to acquire another company or
        companies in transactions with a value exceeding 25% of the acquiror's
        market capitalization. In the event that any such company or companies
        are removed from the Index Group, the weights (which shall be determined
        based upon the number of outstanding shares of common stock) shall be

     3.1  CONVERSION OF SHARES.  Subject to the provisions of this Article 3, at
the Effective Time, by virtue of the Merger and without any action on the part
of UPC, Merger Sub, SFC, or the shareholders of either of the foregoing, the
shares of the constituent corporations shall be converted as follows:
 
          (a) Each share of UPC Capital Stock, including any associated UPC
     Rights, issued and outstanding immediately prior to the Effective Time
     shall remain issued and outstanding from and after the Effective Time.
 
                                       B-2
<PAGE>   108
 
          (b) Each share of Merger Sub Common Stock issued and outstanding at
     the Effective Time shall cease to be outstanding and shall be converted
     into one share of SFC Common Stock.
 
          (c) Each share of SFC Common Stock (excluding shares held by any SFC
     Company or any UPC Company, in each case other than in a fiduciary capacity
     or as a result of debts previously contracted) issued and outstanding at
     the Effective Time shall cease to be outstanding and shall be converted
     into and exchanged for the right to receive .7694 of a share of UPC Common
     Stock (as subject to possible adjustment as set forth in Section 10.1(g) of
     the Merger Agreement, the "Exchange Ratio"). Pursuant to the UPC Rights
     Agreement, each share of UPC Common Stock issued in connection with the
     Merger upon conversion of SFC Common Stock shall be accompanied by a UPC
     Right.
 
     3.2  ANTI-DILUTION PROVISIONS.  In the event UPC changes the number of
shares of UPC Common Stock issued and outstanding prior to the Effective Time as
a result of a stock split, stock dividend, or similar recapitalization with
respect to such stock and the record date therefor (in the case of a stock
dividend) or the effective date thereof (in the case of a stock split or similar
recapitalization for which a record date is not established) shall be prior to
the Effective Time, the Exchange Ratio shall be proportionately adjusted.
 
     3.3  SHARES HELD BY SFC OR UPC.  Each of the shares of SFC Common Stock
held by any SFC Company or by any UPC Company, in each case other than in a
fiduciary capacity or as a result of debts previously contracted, shall be
canceled and retired at the Effective Time and no consideration shall be issued
in exchange therefor.
 
     3.4  FRACTIONAL SHARES.  Notwithstanding any other provision of this
Agreement, each holder of shares of SFC Common Stock exchanged pursuant to the
Merger who would otherwise have been entitled to receive a fraction of a share
of UPC Common Stock (after taking into account all certificates delivered by
such holder) shall receive, in lieu thereof, cash (without interest) in an
amount equal to such fractional part of a share of UPC Common Stock multiplied
by the market value of one share of UPC Common Stock at the Effective Time. The
market value of one share of UPC Common Stock at the Effective Time shall be the
closing price of such common stock on the NYSE-Composite Transactions List (as
reported by The Wall Street Journal or, if not reported thereby, any other
authoritative source selected by UPC) on the last trading day preceding the
Effective Time. No such holder will be entitled to dividends, voting rights, or
any other rights as a shareholder in respect of any fractional shares.
 
     3.5  CONVERSION OF STOCK OPTIONS.
 
          (a) At the Effective Time, each option to purchase or other right with
     respect to shares of SFC Common Stock pursuant to stock options, stock
     appreciation rights or other rights, including stock awards ("SFC Options")
     granted by SFC under the SFC Stock Plans, which are outstanding at the
     Effective Time, whether or not exercisable, shall be converted into and
     become rights with respect to UPC Common Stock, and UPC shall assume each
     SFC Option, in accordance with the terms of the SFC Stock Plan and stock
     option or other agreement by which it is evidenced, except that from and
     after the Effective Time, (i) UPC and its Salary and Benefits Committee
     shall be substituted for SFC and the Committee of SFC's Board of Directors
     (including, if applicable, the entire Board of Directors of SFC)
     administering such SFC Stock Plan, (ii) each SFC Option assumed by UPC may
     be exercised solely for shares of UPC Common Stock (or cash in the case of
     stock appreciation rights), (iii) the number of shares of UPC Common Stock
     subject to such SFC Option shall be equal to the number of shares of SFC
     Common Stock subject to such SFC Option immediately prior to the Effective
     Time multiplied by the Exchange Ratio and rounding down to the nearest
     whole share, and (iv) the per share exercise price under each such SFC
     Option shall be adjusted by dividing the per share exercise price under
     each such SFC Option by the Exchange Ratio and rounding up to the nearest
     cent. Notwithstanding the clauses (iii) and (iv) of the first sentence of
     this Section 3.5, each SFC Option which is an "incentive stock option"
     shall be adjusted as required by Section 424 of the Internal Revenue Code,
     and the regulations promulgated thereunder, so as not to constitute a
     modification, extension or renewal of the option, within the meaning of
     Section 424(h) of the Internal Revenue Code. UPC and SFC agree to take all
     necessary steps to effectuate the foregoing provisions of this Section 3.5.
 
                                       B-3
<PAGE>   109
 
          (b) As soon as practicable after the Effective Time, UPC shall deliver
     to the participants in each SFC Stock Plan an appropriate notice setting
     forth such participant's rights pursuant thereto and the grants subject to
     such SFC Stock Plan shall continue in effect on the same terms and
     conditions (subject to the adjustments required by Section 3.5(a) after
     giving effect to the Merger), and UPC shall comply with the terms of each
     SFC Stock Plan to ensure, to the extent required by, and subject to the
     provisions of, such SFC Stock Plan, that SFC Options which qualified as
     incentive stock options prior to the Effective Time continue to qualify as
     incentive stock options after the Effective Time. Within 30 days after the
     Effective Time, UPC shall file a registration statement on Form S-3 or Form
     S-8, as the case may be (or any successor or other appropriate forms), with
     respect to the shares of UPC Common Stock subject to such options and shall
     use its reasonable efforts to maintain the effectiveness of such
     registration statements (and maintain the current status of the prospectus
     or prospectuses contained therein) for so long as such options remain
     outstanding.
 
                                   ARTICLE 4
                           DELIVERY OF CONSIDERATION
 
     4.1  EXCHANGE PROCEDURES.  Promptly after the Effective Time, UPC and SFC
shall cause the Exchange Agent to mail to the former shareholders of SFC
appropriate transmittal materials (which shall specify that delivery shall be
effected, and risk of loss and title to the certificates theretofore
representing shares of SFC Common Stock shall pass, only upon proper delivery of
such certificates to the Exchange Agent). After the Effective Time, each holder
of shares of SFC Common Stock (other than shares to be canceled pursuant to
Section 3.3 of this Plan of Merger) issued and outstanding at the Effective Time
shall surrender the certificate or certificates representing such shares to the
Exchange Agent and shall promptly upon surrender thereof receive in exchange
therefor the consideration provided in Section 3.1 of this Plan of Merger,
together with all undelivered dividends or distributions in respect of such
shares (without interest thereon) pursuant to Section 4.2 of this Plan of
Merger. To the extent required by Section 3.4 of this Plan of Merger, each
holder of shares of SFC Common Stock issued and outstanding at the Effective
Time also shall receive, upon surrender of the certificate or certificates
representing such shares, cash in lieu of any fractional share of UPC Common
Stock to which such holder may be otherwise entitled (without interest). UPC
shall not be obligated to deliver the consideration to which any former holder
of SFC Common Stock is entitled as a result of the Merger until such holder
surrenders such holder's certificate or certificates representing the shares of
SFC Common Stock for exchange as provided in this Section 4.1. The certificate
or certificates of SFC Common Stock so surrendered shall be duly endorsed as the
Exchange Agent may require. Any other provision of this Plan of Merger
notwithstanding, neither the Surviving Corporation nor the Exchange Agent shall
be liable to a holder of SFC Common Stock for any amounts paid or property
delivered in good faith to a public official pursuant to any applicable
abandoned property Law.
 
     4.2  RIGHTS OF FORMER SFC SHAREHOLDERS.  At the Effective Time, the stock
transfer books of SFC shall be closed as to holders of SFC Common Stock
immediately prior to the Effective Time and no transfer of SFC Common Stock by
any such holder shall thereafter be made or recognized. Until surrendered for
exchange in accordance with the provisions of Section 4.1 of this Plan of
Merger, each certificate theretofore representing shares of SFC Common Stock
(other than shares to be canceled pursuant to Section 3.3 of this Plan of
Merger) shall from and after the Effective Time represent for all purposes only
the right to receive the consideration provided in Sections 3.1 and 3.4 of this
Plan of Merger in exchange therefor, subject, however, to the Surviving
Corporation's obligation to pay any dividends or make any other distributions
with a record date prior to the Effective Time which have been declared or made
by SFC in respect of such shares of SFC Common Stock in accordance with the
terms of this Plan of Merger and which remain unpaid at the Effective Time. To
the extent permitted by Law, former shareholders of record of SFC shall be
entitled to vote after the Effective Time at any meeting of UPC shareholders the
number of whole shares of UPC Common Stock into which their respective shares of
SFC Common Stock are converted, regardless of whether such holders have
exchanged their certificates representing SFC Common Stock for certificates
representing UPC Common Stock in accordance with the provisions of this Plan of
Merger. Whenever a dividend or other distribution is declared by UPC on the UPC
Common Stock, the record date for which is at or after the Effective Time, the
 
                                       B-4
<PAGE>   110
 
declaration shall include dividends or other distributions on all shares
issuable pursuant to this Plan of Merger, but beginning 30 days after the
Effective Time no dividend or other distribution payable to the holders of
record of UPC Common Stock as of any time subsequent to the Effective Time shall
be delivered to the holder of any certificate representing shares of SFC Common
Stock issued and outstanding at the Effective Time until such holder surrenders
such certificate for exchange as provided in Section 4.1 of this Plan of Merger.
However, upon surrender of such SFC Common Stock certificate, both the UPC
Common Stock certificate (together with all such undelivered dividends or other
distributions without interest) and any undelivered dividends and cash payments
to be paid for fractional share interests (without interest) shall be delivered
and paid with respect to each share represented by such certificate.

     5.1  CONDITIONS PRECEDENT.  Consummation of the Merger by Merger Sub shall
be conditioned on the satisfaction of, or waiver by UPC of the conditions
precedent to the Merger set forth in Sections 9.1 and 9.2 of the Merger
Agreement. Consummation of the Merger by SFC shall be conditioned on the
satisfaction of, or waiver by SFC of, of the conditions precedent to the Merger
set forth in Sections 9.1 and 9.3 of the Merger Agreement.
 
     5.2  TERMINATION.  This Plan of Merger may be terminated at any time prior
to the Effective Time by the parties hereto as provided in Article 10 of the

be merged with and into Sho-Me (the "Merger"). The Merger Agreement provides,

         the SEC;

         filed with the SEC;
 
      5. reviewed Sho-Me's unaudited financial statements for the five months
         ended May 31, 1997;

         stock for the period January 1994 through June 23, 1997 and reviewed

         comparable to Sho-Me or UPC, as the case may be;
 
      9. participated in discussions and negotiations among representatives of
         Sho-Me and representatives of UPC;
 
     10. reviewed the financial terms, to the extent publicly available, of
         certain acquisition transactions that FBR deemed to be reasonably
         comparable;
 
     11. reviewed the financial terms, to the extent publicly available, of
         certain acquisition transactions entered into by UPC;
 
     12. reviewed a copy of the Merger Agreement; and
 
     13. performed such other analyses and reviewed and analyzed such other
         information as FBR deemed appropriate.
 
In rendering this opinion, FBR did not assume responsibility for independently
verifying, and did not independently verify, any financial or other information
concerning Sho-Me and UPC furnished to it by Sho-Me or UPC, or the
publicly-available financial and other information regarding Sho-Me, UPC and
other financial institutions (or their holding companies). FBR has assumed that
all such information is accurate and complete. FBR has further relied on the
assurances of management of Sho-Me and UPC that they are not aware of any facts
that would make such financial or other information relating to such entities
inaccurate or misleading. With respect to financial forecasts for Sho-Me
provided to FBR by its management, FBR has assumed, for the purposes of this
opinion, that the forecasts have been reasonably prepared on bases reflecting
the best available estimates and judgments of its management at the time of
preparation as to the future financial performance of Sho-Me. FBR has assumed
that there has been no material change in Sho-Me's assets, financial condition,
result of operations, business or prospects since March 31, 1997. FBR did not
undertake an independent appraisal of the assets or liabilities of Sho-Me nor
was FBR furnished with any such appraisals. FBR is not an expert in the
evaluation of allowances for loan losses, was not requested to and did not
review such allowances, and was not requested to and did not review any
individual credit files of Sho-Me. FBR's conclusions and opinion are necessarily
based upon economic, market and other conditions and the information made
available to FBR as of the date of this opinion. FBR expresses no opinion on
matters of a legal, regulatory, tax or accounting nature related to the Merger.
 
FBR, as part of its institutional brokerage, research and investment banking
practice, is regularly engaged in the valuation of securities and the evaluation
of transactions in connection with mergers and acquisitions of commercial banks,
savings institutions and financial institution holding companies, initial and
secondary offerings, mutual-to-stock conversions of savings institutions, as
well as business valuations for other corporate purposes for financial
institutions and real estate related companies. FBR has experience in, and
knowledge of, the valuation of bank and thrift securities in Missouri, Tennessee
and the rest of the United States.
 
FBR has acted as a financial advisor to Sho-Me in connection with the Merger and
will receive a fee for services rendered which is contingent upon the
consummation of the Merger. In the ordinary course of FBR's business, it may
effect transactions in the securities of Sho-Me or UPC for its own account
and/or for the accounts of its customers and, accordingly, may at any time hold
long or short positions in such securities. From time to time, principals and/or
employees of FBR may also have positions in the securities.
 
Based upon and subject to the foregoing, as well as any such other matters as we
consider relevant, it is FBR's opinion, as of the date hereof, that the
Consideration is fair, from a financial point of view, to the Stockholders of
Sho-Me.
