ITEM 5.  OTHER EVENTS

     On February 4, 2000, Empire Banc Corporation, a Michigan corporation and
registered bank holding company ("Empire") and Huntington Bancshares
Incorporated, a Maryland corporation and a registered bank holding company
("Huntington") entered into an Agreement and Plan of Merger and a Supplemental
Agreement (collectively, the "Merger Agreements") pursuant to which Empire will
be merged with and into Huntington (the "Merger"). As a result of the Merger,
each outstanding share of Empire's common stock, no par value ("Empire Common
Stock") will be converted into 2.0355 shares of Huntington common stock, without
par value. The Merger is conditioned upon, among other things, approval by a
majority vote of the shareholders of Empire, and receipt of certain regulatory
approvals. The Merger Agreements are attached as Exhibits 2.1 and 2.2 and their
terms are incorporated herein by reference.

     Concurrent with the signing of the Merger Agreements, Empire and Huntington
entered into a Warrant Purchase Agreement (the "Warrant Purchase Agreement")
pursuant to which Empire issued a warrant to Huntington (the "Warrant") to
purchase up to 630,080 shares of Empire Common Stock (representing 19.9% of the
outstanding shares) at a price of $29.00 per share and upon the other terms and
conditions set forth in the Warrant. The Warrant Purchase Agreement and the
Warrant are attached as Exhibits to the Supplemental Agreement which is attached
hereto as Exhibit 2.2 and terms of the Warrant Purchase Agreement and the
Warrant are incorporated herein by reference.

     Prior to signing the Merger Agreements, the Warrant Purchase Agreement and
the Warrant, Empire amended its Rights Agreement dated as of December 19, 1990
(the "Rights Agreement Amendment"). The Rights Agreement Amendment exempts
Huntington from the terms of the Rights Agreement and accordingly, the rights
will not separate or become exercisable as a result of the proposed Merger or
the issuance of the Warrant to Huntington. The Rights Agreement Amendment is
attached as Exhibit 4 hereto and its terms are incorporated herein by reference.

     A copy of the press release dated February 7, 2000 issued by Huntington
relating to the Merger is attached as Exhibit 99.

         E.   The respective Boards of Directors of Huntington and Empire have

conditions contained herein.


                                   AGREEMENT:

         NOW, THEREFORE, in consideration of the foregoing recitals, which shall

         Subject to the terms and conditions of this Agreement, and the terms
and conditions contained in a certain Supplemental Agreement, of even date
herewith, among Huntington and Empire (the "Supplemental Agreement"), which is
incorporated by reference in this Agreement, at the "Effective Time" (as such
term is defined in Article 2), Empire shall be merged into Huntington (the
"Merger"). Huntington shall be the surviving corporation in the Merger (the

                              EFFECT OF THE MERGER

         3.1   NAME. The name of the Surviving Corporation shall be "Huntington
Bancshares Incorporated."

         3.2   ARTICLES OF INCORPORATION. The Charter of Huntington in effect at
the Effective Time shall be the charter of the Surviving Corporation, until
amended in accordance with law.

         3.3   SEPARATE CORPORATE EXISTENCE; ASSETS; LIABILITIES. At the
Effective Time, the effect of the Merger shall be as provided by the applicable
provisions of the laws of Maryland. Without limiting the generality of the
foregoing, and subject thereto, at the Effective Time, (1) the separate
existence of Empire shall cease; (2) all assets and property then owned by each
Constituent Corporation, or which would inure to either of them, including all
real, personal, and mixed property, tangible and intangible assets, choses in
action, rights, and credits, and any legacies which either such Constituent
Corporation would have been capable of taking, shall immediately, by operation
of law, transfer to, vest in, and devolve upon the Surviving Corporation,
without any conveyance or further act or deed; (3) the Surviving Corporation
shall be liable for all the debts and obligations of each Constituent
Corporation; and (4) the rights of creditors and any liens on the property or
assets of either Constituent Corporation shall not be impaired.

         3.4   FURTHER ACTIONS. From time to time, as and when requested by the
Surviving Corporation or by its successors, the officers and directors of Empire
in office at the Effective Time shall execute and deliver such instruments and
shall take or cause to be taken such further or other action as shall be
necessary in order to vest or perfect in the Surviving Corporation, or to
confirm of record or otherwise, title to, and possession of, all the assets,
property, interests, rights, privileges, immunities, powers, franchises, and
authority of Empire and otherwise to carry out the purposes of this Agreement.


                                    ARTICLE 4
                              CONVERSION OF SHARES

         4.1   HUNTINGTON COMMON. All shares of Huntington Common that are
issued and outstanding immediately prior to the Effective Time shall continue to
be issued and outstanding shares of Huntington Common at and after the Effective
Time.

         4.2   EMPIRE COMMON.

               (a)   At the Effective Time, the shares of Empire Common issued
and outstanding immediately prior to the Effective Time shall be converted, by
virtue of the Merger and without further action on the part of the holders of
Empire Common (collectively,







                                       8


<PAGE>   4

the "Empire Shareholders" and, individually, a "Empire Shareholder"), into the
right to receive shares of the Huntington Common, as follows:

                  (1)   Subject to adjustment in accordance with Sections (2)
         and (3) below, each outstanding share of Empire Common shall be
         converted into the right to receive 2.0355 shares of Huntington Common
         (the "Conversion Ratio").

                  (2)   If the sum (the "Actual Outstanding Empire Common") of
         (a) the number of shares of Empire Common outstanding at the Effective
         Time plus (b) the number of shares of Empire Common that are subject
         to outstanding Empire Stock Options as of the Effective Time plus (c)
         the number of shares of Empire Common that have been accrued under the
         Director Plans as of the Effective Time is greater than the sum (the
         "Anticipated Outstanding Empire Common") of (x) 3,190,054 shares plus
         (y) the number of shares of Empire Common (not to exceed 19,500
         shares) that have been accrued under the Directors Plans as of the
         Effective Time, the Conversion Ratio will be automatically adjusted by
         multiplying the original Conversion Ratio by the quotient obtained by
         dividing the Anticipated Outstanding Empire Common by the Actual
         Outstanding Empire Common; provided, however, that, in performing any
         such adjustment, the Conversion Ratio will be rounded to the nearest
         hundredth of a share of Huntington Common.

                  (3)   In the event that Huntington changes (or establishes a
         record date for changing) the number of shares of Huntington Common
         issued and outstanding as a result of a stock dividend, stock split,
         recapitalization, or similar transaction with respect to the
         outstanding shares of Huntington Common (collectively, a "Huntington
         Recapitalization"), and the record date for such Huntington
         Recapitalization shall be after the date of this Agreement and prior to
         the Effective Time, then the Conversion Ratio shall be adjusted
         appropriately. In the event of a reclassification of the outstanding
         shares of Huntington Common or a consolidation or merger of Huntington
         with or into another corporation, other than a merger in which
         Huntington is the surviving corporation and which does not result in
         any reclassification, conversion, or exchange of shares of Huntington
         Common, holders of Empire Common shall receive, in lieu of each share
         of Huntington Common to be issued in exchange for each share or portion
         of a share of Empire Common pursuant to the terms hereof, the kind and
         amount of securities, money, property, or other consideration
         receivable upon such reclassification, consolidation, or merger by
         holders of Huntington Common with respect to shares of Huntington
         Common outstanding immediately prior to such reclassification,
         consolidation, or merger.

                  (4)   No fractional shares of Huntington Common shall be
         issued. Each holder of Empire Common who would otherwise be entitled
         to receive a fractional part of a share of Huntington Common shall
         instead be entitled to





                                       9


<PAGE>   5

         receive cash in an amount equal to the product resulting from
         multiplying such fraction by the Average Closing Sale Price. No
         interest shall be payable with respect to such cash payment.

         (b)   Any and all shares of Empire Common held by Empire, Huntington,
or any direct or indirect majority-owned subsidiary of either of them, 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.

         (c)   Each unexercised Empire Stock Option that is outstanding
immediately prior to the Effective Time shall be converted automatically at the
Effective Time into an option to purchase shares of Huntington Common under the
Huntington Amended and Restated 1994 Stock Option Plan or similar Huntington
plan (a "Huntington Stock Option"), with the number of shares of Huntington
Common to be subject to a particular Huntington Stock Option to be determined by
converting the number of shares of Empire Common subject to the Empire Stock
Option into a number of Huntington Common shares in accordance with the
procedure for converting outstanding Empire Common shares into Huntington Common
shares as set forth in Section 4.2(a) above, except that all fractional shares
will be rounded to the nearest whole share, and with the exercise price for each
share of Huntington Common subject to a particular Huntington Stock Option to be
equal to the exercise price per Empire Common share under the Empire Stock
Option divided by the Conversion Ratio determined in accordance with Section
4.2(a)(1) above; provided, however, that, in the case of any Empire Stock Option
to which Section 421 of the Internal Revenue Code of 1986, as amended (the
"Code"), applies by reason of its qualification under Section 422 of the Code,
the terms of the Huntington Stock Option into which such Empire Stock Option is
to be converted, including the option price, the number of shares of Huntington
Common purchasable pursuant to such option, and the terms and conditions of
exercise of such option, shall be determined so as to comply with Section 424(a)
of the Code. Upon such conversion, all rights under any and all stock options
and stock option plans previously granted or adopted by Empire shall terminate.


                                    ARTICLE 5
                            EXCHANGE OF CERTIFICATES

         (a)   As promptly as practicable after the Effective Date but not later
than ten business days after the Effective Date, Huntington shall cause The
Huntington National Bank or its nominee (the "Exchange Agent") to prepare and
mail to each holder of record on the Effective Date of any shares of Empire
Common a letter of transmittal containing instructions for the surrender of all
certificates for shares of Empire Common. Upon the surrender by such holder of a
certificate or certificates for shares of Empire Common standing in such
holder's name to the Exchange Agent in accordance with the instructions set
forth in the letter of transmittal, such holder shall be entitled to receive in
exchange a certificate representing the number of whole shares of Huntington
Common into which the shares represented by the





                                       10

<PAGE>   6


certificate or certificates so surrendered shall have been converted and, if
applicable, a check payable to such holder in the amount necessary to pay for
any fractional shares of Huntington Common which such holder would otherwise
have been entitled to receive, in accordance with Section 4.2(a)(4). Huntington
shall deliver to the Exchange Agent such share certificates for whole shares of
Huntington Common and the amount of cash necessary to pay for all fractional
shares of Huntington Common in accordance with Section 4.2(a)(4) in order to
permit the Exchange Agent to promptly deliver such certificates and cash to the
holders of shares of Empire Common upon its receipt of certificates representing
shares of Empire Common. No interest shall be payable with respect to either the
whole shares of Huntington Common or the cash payable in lieu of fractional
shares. Immediately after the third anniversary of the Effective Date, the
Exchange Agent shall deliver to the Surviving Corporation any unclaimed balance
of cash owing with respect to fractional shares and such cash shall be retained
by, and become the property of the Surviving Corporation, free and clear of any
claims whatsoever.

              (b)   Neither the Surviving Corporation nor the Exchange Agent
shall be obligated to deliver a certificate for Huntington Common or a check for
cash in lieu of fractional shares to a former shareholder of Empire until such
former shareholder surrenders the certificate or certificates representing
shares of Empire Common standing in such former shareholder's name or, if such
former shareholder is unable to locate such certificate or certificates, an
appropriate affidavit of loss and indemnity agreement and bond as may be
required by Huntington. Until so surrendered, each outstanding certificate for
shares of Empire Common shall be deemed for all corporate purposes (except the
payment of dividends) to evidence ownership of the number of whole shares of
Huntington Common into which the shares of Empire Common represented thereby
shall have been converted.

              (c)   After the Effective Date, no dividends or distributions
payable to holders of record of Huntington Common shall be paid to any holder of
an outstanding certificate or certificates formerly representing shares of
Empire Common until such certificate(s) are surrendered by such holder in
accordance with the terms of this Agreement. Promptly upon surrender of such
outstanding certificate(s), there shall be paid to such holder of the
certificate or certificates for Huntington Common issued in exchange the amount
of dividends and other distributions, if any, which theretofore became payable
with respect to such full shares of Huntington Common, but which have not
theretofore been paid on such stock. No interest shall be payable with respect
to the payment of any dividends or other distributions. All such dividends or
other distributions unclaimed at the end of three years from the Effective Date
shall, to the extent such dividends have been previously paid to the Exchange
Agent, be repaid by the Exchange Agent to Huntington, and thereafter the holders
of such outstanding certificates for Empire Common shall look, subject to
applicable escheat, unclaimed funds, and other laws, only to Huntington as
general creditors for payment thereof.

              (d)   The stock transfer books of Empire shall be closed as of
the close of business on the day that is two business days prior to the
Effective Date. After such date,





                                       11

<PAGE>   7


there shall be no further registration on the records of Empire of transfers of
outstanding certificates formerly representing shares of Empire Common.

              (e)   Huntington  is empowered to adopt  additional  reasonable

                    REPRESENTATIONS AND WARRANTIES OF EMPIRE

         Empire hereby represents and warrants to Huntington as follows:

good standing under the Laws of the United States or its respective state of
incorporation or formation and has the corporate power and authority necessary
to carry on its business as now conducted and to own, lease, and operate its
material Assets. Each Empire Company 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 Empire.

         (b)      Section 2.1 of the Disclosure Memorandum contains true and
complete copies of all of the Governing Documents of each Empire Company.

         (c)      Except as disclosed in Section 2.1(c) of the Disclosure

respects all corporate meetings held or actions taken since January 1, 1995, by
the shareholders or Board of Directors of Empire.

         (a)      Empire has the corporate power and authority necessary to
execute, deliver, and perform its obligations under the Merger Documents and to
consummate the transactions contemplated thereby. The execution, delivery, and
performance of the Merger Documents and the consummation of the transactions
contemplated therein, including the Merger, have been duly and validly
authorized by all necessary corporate action in respect thereof on the part of
Empire, subject to the approval of the Merger Documents by a majority of the
outstanding shares of Empire Common, which is the only shareholder vote required
for approval of the Merger Documents and the consummation of the Merger by
Empire. Subject to such requisite shareholder approval, the Merger Documents
represent the legal, valid, and binding obligations of Empire, enforceable
against Empire in accordance with their respective terms (except in all cases as
such enforceability may be limited by applicable bankruptcy, insolvency,
receivership, conservatorship, 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)      Except as disclosed in Section 2.2 of the Disclosure
Memorandum, neither the



                                       30

execution and delivery of the Merger Documents by Empire nor the
consummation by Empire of the transactions contemplated thereby, nor compliance
by Empire with any of the provisions thereof, will (A) conflict with or result
in a breach of any provision of Empire's Governing Documents, or (B) 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 Empire Company, under any Contract
or Permit of any Empire Company, or (C) subject to receipt of the requisite
approvals referred to in Section 7.1(a) and (b) of this Agreement, violate any
Law or Order applicable to any Empire Company or any of their respective
material Assets.

         (c)      Other than in connection or compliance with the provisions of
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 Plan of any Empire Company, no
notice to, filing with, or Consent of, any public body or authority is necessary
for the consummation by Empire of the Merger and the other transactions
contemplated in the Merger Documents.

         2.3      CAPITAL STOCK.

         (a)      The authorized capital stock of Empire consists of 5,000,000
shares of Empire Common, 3,166,234 of which are issued and outstanding as of the

Agreement or as disclosed in Section 2.3 of the Disclosure Memorandum, there are
no shares of capital stock or other equity securities of Empire outstanding and
no outstanding Rights relating to the capital stock of Empire. The execution and

Agreement, (B) result in separation from the shares of Empire Common of the
Rights granted under the Empire Rights Agreement, (C) permit any holder of any

by such entity, or owns any material Assets prohibited to be held by such
entity.

         2.12 LABOR RELATIONS. Except as set forth in Section 2.12 of the
Disclosure Memorandum, no Empire Company is the subject of any Litigation
asserting that it has committed an unfair labor practice (within the meaning of
the National Labor Relations Act or comparable state law) or seeking to compel

Company, pending or, to the Knowledge of Empire, threatened, or, to the
Knowledge of Empire, is there any activity involving any Empire Company's
employees seeking to certify a collective bargaining unit or engaging in any
other organization activity.

         2.13 EMPLOYEE BENEFIT PLANS.

         (a)  Empire has disclosed in Section 2.13 of the Disclosure Memorandum,
and has delivered or made available to Huntington prior to the execution of this
Agreement copies of each Employee Benefit Plan of the Empire Companies.

         (b)  No Empire Company Pension Plan is or has been a "multiemployer
plan" within the meaning of Section 3(37) of ERISA.

         (c)  Except as disclosed in Section 2.13 of the Disclosure Memorandum,
all Employee Benefit Plans of the Empire Companies are in compliance with the
applicable terms of ERISA, the Internal Revenue Code, including the 1986
amendments thereto, 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 Empire or Empire Bank.

         (d)  Except as disclosed in Section 2.13 of the Disclosure Memorandum,
each Empire Company ERISA Plan which is intended to be qualified under Section
401(a) of the Internal Revenue Code has received a favorable determination
letter which takes into account the Tax Reform Act of 1986 and subsequent
legislation for which a determination letter is available from the Internal
Revenue Service, and Empire is not aware of any circumstances likely to result
in revocation of any such favorable determination letter. To the Knowledge of
Empire, no Empire Company has engaged in a transaction with respect to any
Employee Benefit Plan that, assuming the taxable period of such transaction has
not expired as of the date hereof, would subject any Empire Company to a Tax
imposed by either Section 4975 of the Internal Revenue Code or Section 502(i) of
ERISA in amounts which are reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on Empire.

         (e)  Except as disclosed in Section 2.13 of the Disclosure Memorandum,
no Empire Company 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 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 and assuming the adoption of interest rates and
mortality
                                       38
<PAGE>   26

tables described in Section 417(e)(3)(A)(i) and the use of such interest rates
published in January 1999, and assuming that all participants take a lump sum
distribution of their vested accrued benefits on January 1, 1999.

         (f) Except as disclosed in Section 2.13 of the Disclosure Memorandum,
since the date of the most recent actuarial valuation, there has been (A) no
material change in the financial position of any Empire Company Pension Plan,
(B) no change in the actuarial assumptions with respect to any Empire Company
Pension Plan, and (C) no increase in benefits under any Empire Company 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 any Empire Company or materially adversely affect the funding status
of any such plan.

         (g) Except as disclosed in Section 2.13 of the Disclosure Memorandum,
neither any Empire Company Pension Plan nor any "single-employer plan," within
the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by
any Empire Company, or the single-employer plan of any entity which is
considered one employer with Empire 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 Empire
Company has provided, or is required to provide, security to an Empire Company
Pension Plan or to any single-employer plan of an ERISA Affiliate pursuant to
Section 401(a)(29) of the Internal Revenue Code.

         (h) Except as disclosed in Section 2.13 of the Disclosure Memorandum,
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 Empire Company with respect to any ongoing, frozen, or terminated
single-employer plan or the single-employer plan of any ERISA Affiliate, which
Liability is reasonably likely to have a Material Adverse Effect on Empire or
Empire Bank. No Empire Company has incurred any withdrawal Liability with
respect to a multi-employer plan under Subtitle B of Title IV of ERISA
(regardless of whether based on contributions of an ERISA Affiliate), which
Liability is reasonably likely to have a Material Adverse Effect on an Empire
Company. 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 Empire Company Pension Plan or by any ERISA
Affiliate within the 12-month period ending on the date hereof.

         (i) Except as disclosed in Section 2.13 of the Disclosure Memorandum,
no Empire Company has any Liability for retiree health and life benefits under
any Empire Company's Employee Benefit Plans and there are no restrictions on the
rights of such Empire Company to amend or terminate any such Employee Benefit
Plan without incurring any Liability thereunder, which Liability is reasonably
likely to have a Material Adverse Effect on Empire or Empire Bank.

                                       39
<PAGE>   27

         (j)  Except as disclosed in Section 2.13 of the Disclosure Memorandum,
neither the execution and delivery of this Agreement nor the consummation of the
transactions contemplated by the Merger Documents, will (A) result in any
payment (including severance, unemployment compensation, golden parachute, or
otherwise) becoming due to any director, officer, or employee of any Empire
Company from any Empire Company under any Employee Benefit Plan or otherwise,
(B) increase any benefits otherwise payable under any Employee Benefit Plan of
any Empire Company, or (C) result in any acceleration of the time of payment or
vesting of any such benefit.

         (k)  All liabilities under any Empire Company's Employee Benefit Plans,
other than benefits 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 audited Empire Financial Statements to the
extent required by and in accordance with GAAP.

         (l)  Empire Bank is the sponsor of the ESOP and 401(k) Plan. Empire as
parent of Empire Bank will require that the Trustees of the ESOP and the 401(k)
when implementing this Agreement, as it impacts the ESOP and 401(k), comply with
all material and applicable provisions of ERISA and the Internal Revenue Code.
The fiduciary liability insurance issued to Empire applicable to its Employee
Benefit Plans as further described on Section 2.13 of the Disclosure Memorandum
is in full force and effect on the date hereof and will continue to be in full
force and effect through and including the Effective Date.

         Regulation S-K of the Securities and Exchange Commission; and

         (6)  any contract, arrangement, commitment, or understanding which

Adverse Effect on Empire; (C) Empire has not repudiated or waived any material

to the knowledge of Empire, in Default in any respect, other than Defaults which

Adverse Effect on Empire, or has repudiated or waived any material provision
thereunder.

         2.15 LEGAL PROCEEDINGS. Except as disclosed in Section 2.15 of the
Disclosure Memorandum, there is no Litigation instituted or pending or, to the
Knowledge of Empire, threatened (or unasserted but considered probable of
assertion) against any Empire Company, or against any Asset, interest, or right
of any of them, nor are there any Orders of any Regulatory Authorities, other
governmental authorities, or arbitrators outstanding against any Empire Company.
Section 2.15 of the Disclosure Memorandum contains a copy of each audit letter
response received by Empire from attorneys for any Empire Company in connection
with the preparation of the Financial Statements of Empire or otherwise since

Agreement to which any Empire Company is a party and which names any Empire
Company as a defendant or cross-defendant, and a brief summary report of any

later, each Empire Company has timely filed all material reports and statements,
together with any amendments required to be made with respect thereto, that it

individually or in the aggregate, a Material Adverse Effect on Empire. 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

<PAGE>   29

         2.17 STATEMENTS TRUE AND CORRECT. None of the information supplied or

Proxy Statement to be mailed to Empire's shareholders in connection with the
Shareholders' Meeting and any other documents to be filed by Empire or any
Affiliate thereof with the SEC or any other Regulatory Authority in connection

form in all material respects with the provisions of applicable Law.

         2.18 TAX AND REGULATORY MATTERS. No Empire Company nor, to the
Knowledge of Empire, any Affiliate thereof, has taken any action or has any
Knowledge of any fact or circumstance that is reasonably likely to (A) prevent
the transactions contemplated by the Merger Documents, including the Merger,
from qualifying as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code, or (B) materially impede or delay receipt of any Consents
of Regulatory Authorities referred to in Section 7.1(b) of this Agreement or

in the last sentence of such Section.

         2.19 STATE TAKEOVER LAWS. Each Empire Company has taken all necessary
steps to exempt the transactions contemplated by the Merger Documents from any

         2.20 CHARTER PROVISIONS. Empire has taken all action so that the

other transactions contemplated by the Merger Documents do not and will not
result in the grant of any rights to any Person under the Governing Documents of
any Empire Company or restrict or impair the ability of Huntington or any of its
Subsidiaries to vote, or otherwise to exercise the rights of a shareholder with
respect to, shares of Empire that may be directly or indirectly acquired or
controlled by Huntington or any of its Subsidiaries.

         2.21 COMPLIANCE WITH CERTAIN LAWS. Except as disclosed in Section 2.21

<PAGE>   30

Disclosure Memorandum, Empire is in compliance with all currently applicable
capital requirements and guidelines prescribed by all appropriate federal or

received any notice of non-compliance with the applicable provisions of the CRA
and the regulations promulgated thereunder, and Empire Bank has received a CRA
rating of satisfactory or better from the OCC. Empire knows of no fact or
circumstance or set of facts or circumstances which would cause Empire to fail
to comply with such provisions or to cause the CRA rating of Empire to fall
below satisfactory.

         2.23 ACQUISITION TRANSACTIONS. Except with respect to the Merger
Documents, there are no proposals or offers to engage in an Acquisition
Transaction previously received by Empire which remain outstanding as of the
close of business on February 4, 2000. Any breach of this representation by
Empire will cause any such proposal or offer, whether in its original form or as
amended, to be deemed to be received by Empire after February 4, 2000, for
purposes of Section 1 of the Warrant and Section 10.2 of this Agreement.

         2.24 LUMP SUM PAYMENT, RELEASE, AND WAIVER AGREEMENTS. Huntington,
Empire, and each of the executives officers of Empire listed in Section
2.14(a)(2) of the Disclosure Memorandum (the "Executives"), have entered into

the payment of cash in lieu of benefits otherwise payable to the Executives upon
a change in control of Empire. Empire has the corporate power and authority
necessary to execute, deliver, and perform its obligations under such Lump Sum
Payment, Release, and Waiver Agreements and the execution, delivery, and
performance of the such Lump Sum Payment, Release, and Waiver Agreement have
been duly and validly authorized by all necessary corporate action in respect
thereof on the part of Empire. Each Lump Sum Payment, Release, and Waiver
Agreement represents the legal, valid, and binding obligation of Empire and the
relevant Executive, enforceable against Empire and the relevant Executive in
accordance with its terms (except in all cases as such enforceability may be
limited by applicable bankruptcy, insolvency, receivership, conservatorship,
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).

                  REPRESENTATIONS AND WARRANTIES OF HUNTINGTON

         3.2 AUTHORITY; NO BREACH BY AGREEMENT.

         (a) Huntington has the corporate power and authority necessary to
execute, deliver and perform its obligations under the Merger Documents and to
consummate the transactions contemplated thereby. The execution, delivery and
performance of the Merger Documents 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 Huntington. The Merger Documents represent the legal, valid, and binding
obligations of Huntington, enforceable against Huntington in accordance with
their respective 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 the Merger Documents by
Huntington, nor the consummation by Huntington of the transactions contemplated
thereby, nor compliance by Huntington with any of the provisions thereof or
hereof, will (A) conflict with or result in a breach of any provision of
Huntington's Governing Documents, or (B) constitute or result in a Default
under, or, subject to receipt of the requisite approval referred to in Section
7.1(b) of this Agreement, require any Consent pursuant to, or result in the
creation of any Lien on any Asset of any Huntington Company under, any Contract
or Permit of any Huntington Company, or, (C) subject to receipt of the requisite
approvals referred to in Section 7.1(b) of this Agreement, violate any Law or
Order applicable to any Huntington 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, no notice to, filing with, or Consent of, any public body
or authority is necessary for the consummation by Huntington of the Merger and
the other transactions contemplated in the Merger Documents.

         3.3 CAPITAL STOCK.

         (a) The authorized capital stock of Huntington consists of (A)
500,000,000 shares of Huntington Common, of which 227,992,927 shares were issued
and outstanding as of January 31, 2000, and (B) 6,617,808 shares of Huntington
Preferred Stock, none of which are issued or outstanding. Huntington has taken
all corporate action necessary to reserve for issuance a sufficient number of
shares of Huntington Common for delivery in exchange for shares of Empire Common
upon consummation of the Merger. All of the issued and outstanding shares of
Huntington Common are, and all of the shares of Huntington Common to be issued
in exchange for shares of Empire Common 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. None of the outstanding
shares of Huntington Capital Stock has been, and none of the shares of
Huntington Common to be issued in exchange for shares of Empire Common upon
consummation of the Merger will be, issued in violation of any preemptive rights
of the current or past shareholders of Huntington.

         (b) There are no Rights relating to the outstanding shares of
Huntington Common other than those provided under the Huntington Rights
Agreement and each outstanding share of Huntington Common, including those to be
issued to the shareholders of Empire in the Merger will have the Rights provided
under the Huntington Rights Agreement. The execution and delivery of the Merger
Documents does not, and the consummation of the Merger and the other
transactions contemplated by the Merger Documents will not, (A) result in the
grant of any Rights to any Person under the Huntington Rights Agreement, (B)
result in separation from the shares of Huntington Common of the Rights granted
under the Huntington Rights Agreement, (C) permit any holder of any of the
Rights under the Huntington Rights Agreement to exercise any such Rights, or (D)
give any Person any Right to purchase any securities issued by Huntington (other
than to Empire's shareholders as contemplated in the Merger Agreement).

         (c) Huntington has taken all corporate action necessary to reserve for
issuance a sufficient number of shares of Huntington Common for delivery upon
the exercise of the Empire Stock Options to be converted in accordance with the
terms of the Merger Agreement, and the shares of Huntington Common issuable upon
the exercise of the Empire Stock Options so converted shall be included under an
existing effective registration statement with respect to such shares of
Huntington Common.

         3.4 HUNTINGTON SUBSIDIARIES. Huntington or one of its Subsidiaries owns
all of the issued and outstanding shares of capital stock of each material
Huntington Subsidiary. No equity securities of any material Huntington
Subsidiary are or may become required to be issued by reason of any Rights, and
there are no Contracts by which any material Huntington Subsidiary is bound to
issue additional shares of its capital stock or Rights. There are no Contracts
relating to the rights of any Huntington Company to vote or to dispose of any
shares of the capital stock of any material Huntington Subsidiary. All of the
shares of capital stock of each Huntington Subsidiary held by a Huntington
Company are fully paid and, except pursuant

                                       45

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
Huntington 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 Huntington. The Huntington National Bank is an "insured institution,"
as defined in the Federal Deposit Insurance Act and applicable regulations
thereunder, the deposits in which are insured by the Bank Insurance Fund.

         3.5 FINANCIAL STATEMENTS. Huntington has delivered to Empire all

consistency specified therein or as may be indicated in the notes thereto or, in
the case of interim financial statements, to normal recurring year-end
adjustments that are not material in amount or effect).

         3.6 ABSENCE OF UNDISCLOSED LIABILITIES. No Huntington Company has any
Liabilities that are reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on Huntington, except Liabilities which are
accrued or reserved against in the consolidated balance sheets of Huntington as

prior to the date of this Agreement or reflected in the notes thereto.

Huntington Financial Statements delivered prior to the date of this Agreement,

which have had, or are reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on Huntington, and (B) Huntington has not
taken any action, or failed to take any action, prior to the date of this

         3.8 TAX MATTERS.

         (a) All Tax returns required to be filed by or on behalf of any of the
Huntington 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, 1998, and on or before the date of the most recent fiscal year end
immediately preceding the Effective Time and all returns filed are complete and
accurate, except for failures, if any, which, taken together, would not have a
Material Adverse Effect on Huntington. All Taxes shown on filed returns have
been paid or adequate provision therefor has been made in the Huntington
Financial Statements. As of the date of this Agreement, there is no audit
examination, deficiency, or refund Litigation with respect to any Taxes that is
reasonably likely to result in a determination that would have, individually or
in the aggregate, a Material Adverse Effect on Huntington, except as reserved
against in the Huntington Financial Statements. All Taxes and other Liabilities
due with respect to completed and settled Tax examinations or concluded Tax
Litigation have been paid or adequate provision therefor has been made in the
Huntington Financial Statements.

         (b) None of the Huntington Companies has executed an extension or
waiver of any statute of limitations on the assessment or collection of any Tax
due (excluding such statutes that relate to years currently under examination by
the Internal Revenue Service or other applicable taxing authorities) that is
currently in effect.

         (c) Adequate provision for any Taxes due or to become due for any of
the Huntington Companies for the period or periods through and including the

reflected on such Huntington Financial Statements.

         (d) Deferred Taxes of the Huntington Companies have been provided for
in accordance with GAAP.

         (e) Each of the Huntington Companies is in material compliance with,
and its records contain all information and documents (including properly
completed IRS Forms W-9) necessary to 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.

         3.9 ASSETS AND  INSURANCE.  Except to the extent that an exception to
any of the matters described below would not be reasonably likely to have a
Material Adverse Effect on Huntington:

         (a) Except as disclosed or reserved against in the Huntington Financial
Statements, Huntington has good and marketable title, free and clear of all
Liens, to all of its Assets which

                                     47
<PAGE>   35

are material to the operation of its business. All Assets which are material to
Huntington's business and that are held under leases or subleases by Huntington,
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.

         (b) To its Knowledge, Huntington currently maintains insurance and
blanket bonds (collectively, "Insurance") similar in amounts, scope, and
coverage to that customarily maintained by other bank organizations comparable
in size and operation to Huntington. Huntington has not received notice from any
Insurance carrier that (A) such Insurance will be canceled or that coverage
thereunder will be reduced or eliminated, or (B) premium costs with respect to
such policies of insurance will be substantially increased. All premiums due
under the policies of Insurance have been paid.

         3.10 COMPLIANCE WITH LAWS. Each Huntington 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, except for those Permits the absence of
which are not reasonably likely to have, individually or in the aggregate, a
Material Adverse Effect on Huntington, and there has occurred no Default under
any such Permit, other than Defaults which are not reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on Huntington. No
Huntington Company:

         (a) is in Default under its Governing Documents;

         (b) is in violation of, or in Default under, any Laws, Order or Permits
applicable to its business or employees conducting its business, except for
violations which are not reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on Huntington;

         (c) 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 (A) asserting that any Huntington Company is not in compliance
with any of the Laws or Orders, including CRA, which such governmental authority
or Regulatory Authority enforces, where such noncompliance is reasonably likely
to have, individually or in the aggregate, a Material Adverse Effect on
Huntington or which would prevent or delay the consummation of the transactions
contemplated under the Merger Documents, (B) threatening to revoke any Permits,
the revocation of which is reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on Huntington, (C) requiring any Huntington
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 resolution of the Board of Directors of such entity, or similar
undertaking, which restricts materially the conduct of its

                                       48
<PAGE>   36

business, or in the payment of dividends, or which are reasonably likely to
delay or prevent the consummation of the transactions contemplated herein; or

         (d)  directly or indirectly  engages in any material  activity

prohibited to be held by such entity.

         3.11 EMPLOYEE BENEFIT PLANS.

         (a)  Huntington has delivered or made available to Empire prior to the
execution of this Agreement copies of all Huntington Employee Benefit Plans
currently adopted, maintained by, sponsored in whole or in part by, or
contributed to by any Huntington Company which are applicable to employees
generally of the Huntington Companies.

         (b)  All Huntington Benefit Plans are in compliance with the applicable
terms of ERISA, the Internal Revenue Code including the 1986 amendments thereto
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
Huntington.

         (c)  Each Huntington ERISA Plan which is intended to be qualified under
Section 401(a) of the Internal Revenue Code has received a favorable
determination letter which takes into account the Tax Reform Act of 1986 and
subsequent legislation for which a determination letter is available from the
Internal Revenue Service, and Huntington is not aware of any circumstances
likely to result in revocation of any such favorable determination letter.

         3.12 LEGAL PROCEEDINGS. There is no Litigation instituted or pending
or, to the Knowledge of Huntington, 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 Huntington Company, or
against any Asset, interest, or right of any of them, that seeks to enjoin,
delay or prevent the execution, delivery, or performance of the Merger Documents
or the completion of the transactions contemplated therein, or that, if a
judgment adverse to a Huntington Company were to be rendered in such Litigation,
would have, individually or in the aggregate, a Material Adverse Effect on
Huntington, nor are there any Orders of any Regulatory Authorities, other
governmental authorities, or arbitrators outstanding against any Huntington
Company, that would have, individually, or in the aggregate, a Material Adverse
Effect on Huntington.

         3.13 REPORTS. Since January 1, 1995, Huntington has filed all reports
and statements, together with any amendments required to be made with respect
thereto, that it was required to file with (A) the SEC, including, but not
limited to, Forms 10-K, Forms 10-Q, Forms 8-K, and proxy statements, (B) other
Regulatory Authorities, and (C) any applicable state securities or bank
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 Huntington). As of their respective dates, each of
such reports and documents, including the financial statements, exhibits, and
schedules thereto, complied in all

                                       49
<PAGE>   37
material respects with all applicable Laws. As of its respective date, each such
report and document did not 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.

         3.14 STATEMENTS TRUE AND CORRECT. None of the information supplied or
to be supplied by Huntington or any Affiliate thereof for inclusion in the
Registration Statement to be filed by Huntington 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 Huntington or any Affiliate thereof for inclusion in the Proxy
Statement to be mailed to Empire's shareholders in connection with the
Shareholders' Meeting, and any other documents to be filed by Huntington or any
Affiliate thereof with the SEC or any other Regulatory Authority in connection
with the transactions contemplated by the Merger Documents, will, at the
respective time such documents are filed, and with respect to the Proxy
Statement, when first mailed to the shareholders of Empire, 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 Huntington or any Affiliate thereof is
responsible for filing with any Regulatory Authority in connection with the
transactions contemplated by the Merger Documents will comply as to form in all
material respects with the provisions of applicable Law.

         3.15 TAX AND REGULATORY MATTERS. No Huntington Company or any Affiliate
thereof has taken any action or has any Knowledge of any fact or circumstance
that is reasonably likely to (A) prevent the transactions contemplated by the
Merger Documents, including the Merger, from qualifying as a reorganization
within the meaning of Section 368(a) of the Internal Revenue Code, or (B)
materially impede or delay receipt of any Consents of Regulatory Authorities
referred to in Section 7.1(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.

         3.16 COMMUNITY REINVESTMENT ACT COMPLIANCE. The Huntington National
Bank has received a CRA rating of satisfactory or better from the OCC.
Huntington knows of no fact or circumstance or set of facts or circumstances
which would cause the CRA rating of The Huntington National Bank to fall below
satisfactory.

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

         4.5 AGREEMENT AS TO EFFORTS TO CONSUMMATE. Subject to the terms and
conditions of this Agreement, each Party agrees to use, and to cause its

actions, and to do, or cause to be done, all things necessary, proper, or
advisable under applicable Laws to consummate and make effective, as soon as
practicable after the date of this Agreement, the transactions contemplated by
the Merger Documents, including using its reasonable efforts to lift or rescind
any Order adversely affecting its ability to consummate such transactions and to
cause to be satisfied the conditions referred to in Article 7 of this Agreement;
provided, that nothing herein shall preclude either Party from exercising its
rights under this Agreement. Each Party shall use, and shall cause each of its
Subsidiaries to use, its reasonable efforts to obtain all Consents necessary or

with the transactions contemplated by the Merger Documents.

         4.6 INVESTIGATION AND CONFIDENTIALITY.

         (a) Prior to the Effective Time, each Party shall keep the other Party
advised of all material developments relevant to its business and to
consummation of the Merger and shall permit the other Party to make or 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 made after
reasonable prior notice and during regular business hours, shall be reasonably
related to the transactions contemplated by the Merger Documents, and shall not
interfere unnecessarily with normal operations. No investigation by a Party
shall affect the representations and warranties of the other Party.

         (b) Each Party shall, and shall cause its advisers and agents to,
maintain the confidentiality of all confidential information furnished to it by
the other Party concerning its and its Subsidiaries' businesses, operations, and

shall promptly return or certify the destruction of all documents and copies
thereof, and all work papers containing confidential information received from
the other Party.

         (c) Each Party agrees to give the other Party notice as soon as
practicable after any determination by it of any fact or occurrence relating to
the other Party which it has discovered through the course of its investigation
and which represents, or is reasonably likely to represent, either a material
breach of any representation, warranty, covenant, or agreement of the other
Party or which has had or is reasonably likely to have a Material Adverse Effect
on the other Party.

         (d) Promptly after the execution of this Agreement, Empire will use its

counsel deems necessary or advisable in order to satisfy such Party's disclosure
obligations imposed by Law.

         4.8 TAX TREATMENT. Each of the Parties undertakes and agrees to use its
reasonable efforts to cause the Merger, and to take no action which would cause
the Merger not, to qualify for treatment as a "reorganization" within the
meaning of Section 368(a) of the Internal Revenue Code for federal income tax
purposes.

         4.9 NO RIGHTS TRIGGERED. Each Party shall take all reasonable steps
necessary to ensure that entering into the Merger Documents and the consummation

result in the grant of any Rights to any Person under the Empire Rights
Agreement or the Huntington Rights Agreement, (C) result in separation from the
shares of Empire Common of the Rights granted under the Empire Rights Agreement
or separation from the shares of Huntington Common of the Rights granted under
the Huntington Rights Agreement, (D) permit any holder of any of the Rights
under the Empire Rights Agreement or the Huntington Rights Agreement to exercise
any such Rights, or (E) give any Person any Right to purchase any securities
issued by Huntington except as contemplated by the Merger.

         (m)  make any significant change in any Tax or accounting methods or

         5.3  CERTAIN ACTIONS. Except with respect to the Merger Documents and
the transactions contemplated thereby, neither Empire nor any Affiliate or any

duties of Empire's Board of Directors, as advised by counsel, entertain, any
proposal to engage in an Acquisition Transaction by any






                                       56


<PAGE>   44


Person. Except to the extent necessary to comply with the fiduciary duties of
Empire's Board of Directors, as advised by counsel, neither Empire nor any
Affiliate or Representative thereof shall fail to recommend that Empire
shareholders vote in favor of the Merger or withdraw such as recommendation
previously made, fail to solicit proxies of the shareholders of Empire, or fail
to hold the Shareholders' Meeting, or shall furnish any non-public information
that it is not legally obligated to furnish in connection with, negotiate with
respect to, or enter into any Contract with respect to, any Acquisition
Transaction, but Empire may communicate and disclose information about such a
proposal to engage in an Acquisition Transaction 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. Empire shall promptly notify Huntington
orally and in writing in the event that it receives any inquiry or proposal
relating to any Acquisition Transaction. Empire shall (A) 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
(B) direct and use its reasonable efforts to cause all of its Representatives
not to engage in any of the foregoing. Notwithstanding anything contained in the
Merger Documents to the contrary, any action taken by Empire or its Affiliates
or Representatives which is permitted under this Section 5.3 by virtue of such
action being necessary to comply with the fiduciary duties of Empire's Board of
Directors, as advised by counsel, shall not constitute a breach of any of the
Merger Documents by Empire.

         5.4  AGREEMENTS WITH RESPECT TO AFFILIATES. Empire has disclosed in
Section 5.4 of the Disclosure Memorandum all Persons whom it reasonably believes
is an "affiliate" of Empire for purposes of Rule 145 under the 1933 Act. Empire
shall use its reasonable efforts to cause each such Person to deliver to
Huntington not later than 30 days prior to the Effective Time, a written
agreement, in a form reasonably satisfactory to both parties, providing that
such Person will not sell, pledge, transfer, or otherwise dispose of the shares
of Empire Common held by such Person except as contemplated by such agreement or
by the Merger Documents and will not sell, pledge, transfer, or otherwise
dispose of the shares of Huntington Common to be received by such Person upon
consummation of the Merger except in compliance with applicable provisions of
the 1933 Act.

         5.5  CERTAIN POLICIES OF EMPIRE. At the request of Huntington, Empire
shall use its best efforts to modify and change its loan, litigation, and real
estate valuation policies and practices (including loan classifications and
levels of reserves) prior to the Effective Time so as to be consistent on a
mutually satisfactory basis with those of Huntington and GAAP. Empire shall not
be required to modify or change any such policies or practices, however, until
such time as (A) the conditions set forth in Sections 7.1(a), 7.1(b), and 7.1(c)
of this Agreement have been satisfied, (B) Empire and Huntington agree that the
Effective Time will occur prior to the public disclosure of such modifications
or changes in regular periodic earnings releases or periodic reports filed with
the Regulatory Authorities, and (C) Huntington acknowledges in writing that all
conditions to its obligation to consummate the Merger (and Huntington's rights
to terminate this Agreement) have been waived or satisfied; provided, that in
all circumstances Empire shall make such modifications and changes not later
than immediately prior to the Effective Time. Empire's representations,
warranties, covenants, and agreements contained in






                                       57

<PAGE>   45

this Agreement shall not be deemed to be untrue or breached in any respect for
any purpose as a consequence of any modifications or changes undertaken solely
on account of this Section 5.5.

         5.6  TITLE INSURANCE. For each parcel of Operational Real Property
described in the Disclosure Memorandum as being owned by an Empire Company,
Empire shall deliver to Huntington, at Empire's expense, no later than 60 days
after the date of this Agreement, a title insurance commitment (ALTA 1966 form
or its equivalent) for a fee owner's title insurance policy, each in an amount
equal to the carrying cost of the premises or leasehold interest to be insured
(including all improvements thereon), on the books of Empire as of December 31,
1998. Each title insurance commitment shall show that marketable fee simple
title to the owned premises is in the name of an Empire Company, and that the
owned premises are free and clear of any Liens and encumbrances which would have
a Material Adverse Effect on Empire except taxes and assessments not delinquent
and utility and other easements that do not interfere with the use of the
property for the business being conducted thereon. Each such commitment shall
provide that such fee owners policy committed for therein shall be an ALTA 1970
form, revised in 1984, or other form acceptable to Huntington.

         5.7  SURVEYS. Within 60 days after the date of this Agreement,
Empire shall provide to Huntington, at Empire's expense, current land surveys of
those parcels of the Operational Real Property specifically designated by
Huntington. Each survey shall be conducted and prepared by a duly licensed land
surveyor approved by Huntington and, unless otherwise agreed by Huntington in
writing, shall be a duly certified ALTA/ACSM field survey, which shall comply
with the requirements set forth in Huntington's Standard Survey Requirements, a
copy of which has been furnished to Empire prior to the execution of this
Agreement, and shall confirm that the Operational Real Property is not subject
to any easements, restrictions, set backs, encroachments, or other limitations
which would have a Material Adverse Effect on Empire except for utility and
other easements that do not interfere with the use of the Operational Real
Property for the business then being conducted thereon, and that the Operational
Real Property is not located in any flood hazard area.

         5.8  ENVIRONMENTAL ASSESSMENT. Empire shall obtain and deliver to
Huntington, at Empire's expense, on or before the date which is 60 days after
the date of this Agreement, a Phase I Environmental Site Assessment (the "Phase
I Assessment") for each tract of Operational Real Property from a consultant
acceptable to Huntington. The Phase I Assessment shall be performed in
accordance with the requirements of The Huntington National Bank Phase I (ESA)
Checklist - Minimum Requirements, a copy of which has been furnished to Empire
prior to the execution of this Agreement. Each Phase I Assessment shall reveal
no facts that establish a reason to believe that any Hazardous Substances have
been treated, stored, managed, or disposed of on the Operational Real Property
as would be reasonably likely to have a Material Adverse Effect on Empire.

                             COVENANTS OF HUNTINGTON

         6.1  NEGATIVE COVENANTS OF HUNTINGTON. From the date of this Agreement
until the earlier of the Effective Time or the termination of this Agreement,
Huntington covenants and agrees that it will not do or agree or commit to do, or
permit any of its Subsidiaries to do or agree or commit to do, any of the
following without the prior written consent of the chief executive officer of
Empire, which consent shall not be unreasonably withheld:

         (a)  take any action which to its Knowledge at the time of such action,
would (A) materially adversely affect the ability of any Party to consummate the
transactions contemplated under the Merger Documents, (B) materially adversely
affect the ability of any Party to obtain any Consents required to consummate
the transactions contemplated under the Merger Documents without imposition of a
condition or restriction of the type referred to in the last sentences of
Section 7.1(b) or 7.1(c) of this Agreement, or (C) materially adversely affect
the ability of any Party to perform its covenants and agreements under the
Merger Documents;

         (b)  amend the Governing Documents of Huntington or the Huntington
Rights Agreement, in each case, in any manner adverse to the holders of Empire
Common as compared to rights of holders of Huntington Common generally as of the
date of this Agreement;

         (c)  take any action that is intended or may reasonably be expected to
result in (A) any of its representations and warranties set forth in this
Agreement being or becoming untrue in any material respect at any time prior to
the Effective Time, (B) any of the conditions to the Merger set forth in Article
7 hereof not being satisfied, or (C) a violation of any provisions of the Merger
Documents, except, in every case, as may be required by applicable Law.

         6.2  NASDAQ LISTING. Huntington shall use its reasonable efforts to
provide, prior to the Effective Time, for quotation on the Nasdaq National
Market the shares of Huntington Common to be issued to the holders of shares of
Empire Common pursuant to the Merger, and Huntington shall give all notices and
make all filings with the NASD, required in connection with the transactions
contemplated herein.

         6.3  EMPLOYEE BENEFITS AND CONTRACTS.

         (a)  Except as set forth in this Agreement, or in Section 4.2(c) of the
Merger Agreement relating to the conversion of Empire Stock Options, following
the Effective Time, Huntington shall provide to officers and employees of Empire
who become officers or employees of any Huntington Company after the Effective
Time employee benefits under Huntington Benefit Plans, and stock option and
other plans involving the potential issuance of Huntington Common Stock, on
terms and conditions which when taken as a whole are substantially similar to
those currently provided generally by Huntington and its Affiliates to







                                       59

<PAGE>   47

their similarly situated officers and employees. For purposes of participation
and vesting under such Huntington Benefit Plans, the service of the employees of
the Empire Companies (calculated pursuant to applicable Empire Benefit Plans)
prior to the Effective Time shall be treated as service with a Huntington
Company participating in such Huntington Benefit Plans. Furthermore, officers
and employees of Empire Companies (and their spouses and dependents, if
applicable) may, upon the cessation of their participation in an Empire Benefit
Plan, immediately participate in the corresponding Employee Benefit Plan
maintained by Huntington without regard to pre-existing conditions or waiting
periods. Benefit accruals under any Huntington Pension Plan will not be offset
by benefit accruals under any Empire Pension Plan; however, in the event the
Empire Pension Plan merges with the Huntington Pension Plan, and if benefit
accruals under the Empire Pension Plan cease, the Huntington Pension Plan will
provide future benefit accruals under the Huntington Pension Plan that are no
less than those benefits that would accrue assuming the Huntington Pension Plan
implements a "fresh start formula without wear away" (as described in Treasury
Regulation ss. 1.401(a)(4)-13(c)(4)(i)).

         (b)  Huntington undertakes and agrees to provide all persons who are
employed by Empire immediately prior to the Effective Time with severance
benefits consistent with Huntington's Transition Pay Plan as in effect as of the
Effective Time, which benefits will not be less than those provided under such
plan as of the date of this Agreement. For purposes of calculating benefits and
determining an individual's years of service under Huntington's Transition Pay
Plan, the service of an Empire Company's employee prior to the Effective Time
commencing with that employee's most recent hire date by the Empire Company
shall be treated as service with a Huntington Company. Notwithstanding the
foregoing, during the 12-month period following the Effective Time, those
officers and employees of the Empire Companies listed in Sections 6.3(a) and
6.3(b) of the Disclosure Memorandum whose employment with an Empire Company or a
Huntington Company, as the case may be, is terminated due to job elimination or
is terminated by Huntington or its Affiliates without cause, shall be paid
severance benefits upon termination of not less than 50% of their annual base
salary without offset with respect to compensation or other benefits received
from a subsequent employer. Huntington further agrees to provide out-placement
services for a period of six months following such termination to those persons
identified in Section 6.3(b) of the Disclosure Memorandum.

         (c)  Huntington agrees that bonuses in an aggregate amount not to
exceed the Empire Bonus Pool shall be paid to the Empire Bonus Plan Participants
in the amounts to be listed on a supplement to Section 6.3(c) of the Disclosure
Memorandum (the "Section 6.3(c) Supplement") which shall be delivered to
Huntington on or before the Effective Date; provided, however, that such bonus
payments will only be made to Empire Bonus Plan Participants who are employed by
Empire or Huntington or their Affiliates on December 31, 2000, or who were
terminated by Huntington or its Affiliates prior to December 31, 2000, without
cause or due to job elimination, in which event the aggregate Empire Bonus Pool
shall be reduced by the amount of payments allocated to such Empire Bonus Plan
Participants who are no longer eligible to receive the bonus payments.
Huntington shall pay any and all such bonus payments to such eligible Empire
Bonus Pool Participants on or before February 15,






                                       60

<PAGE>   48

2001. The Section 6.3(c) Supplement will update the list of Empire Bonus Plan
Participants and confirm their eligibility pursuant to the Empire Bonus Plan as
of the Effective Date and will indicate the allocation of the Empire Bonus Pool
among such Empire Bonus Plan Participants, which allocation shall be consistent
with past practices.

         (d)  Immediately prior to the Effective Time, Empire will pay out to
each participant in the Director Plans all cash accrued to such participant
under the Director Plans (estimated to be $828,374 in the aggregate at June 30,
2000) and distribute to each participant in the Director Plans all shares of
Empire Common allocated for issuance to such participant under such Director's
Plans up to 19,500 shares and Empire shall terminate such Plans effective as of
the Effective Time.

         6.4  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         (a)  For a period of six years after the Effective Time, to the fullest
extent permitted by applicable Law, Huntington shall, and shall cause its
Subsidiaries to, indemnify, defend, and hold harmless the present and former
directors, officers, employees, and agents of the Empire Companies (each, an
"Indemnified Party") against all Liabilities arising out of actions or omissions
arising out of the Indemnified Party's service or services as directors,
officers, employees, or agents of Empire or, at Empire's request, of another
corporation, partnership, joint venture, trust, or other enterprise occurring at
or prior to the Effective Time (including the transactions contemplated by the
Merger Documents), including provisions relating to advances of expenses
incurred in the defense of any Litigation, with respect to any Liability, claim,
demand, action, or Litigation asserted or made prior to or at any time after the
Effective Time. All such rights to indemnification with respect to any such
Liability, claim, demand, or action shall continue until the final disposition
of such Litigation and/or Liability; provided, however, that nothing contained
herein shall increase or lengthen the duration of obligations with respect to
such indemnification by the Huntington or any other Huntington Company over that
to which Empire would have been subject had the Merger not been consummated. All
rights to exculpation from liability and limitation of liability provided by
this Section 6.4 shall survive the Effective Time and the consummation of the
Merger. Without limiting the foregoing, in any case in which approval by
Huntington is required to effectuate any indemnification, Huntington 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
Huntington and the Indemnified Party.

         (b)  The  provisions  of this Section 6.4 are  intended to be for the
benefit of, and shall be enforceable by, each Indemnified Party and each
Indemnified Party's heirs and representatives.

<PAGE>   49


         6.5  STOCK OPTIONS.

         (a)  At the Effective Time, each outstanding  Empire Stock Option shall
be converted into an option to purchase shares of Huntington Common in
accordance with the terms of the Merger Agreement.

         (b)  As soon as practicable after the Effective Time, Huntington shall
deliver to the holders of such converted Empire Stock Options appropriate
notices setting forth such holders' rights pursuant to the Huntington Stock
Option Plan and the agreements evidencing such converted Empire Stock Options.

         (c)  Huntington shall use all reasonable efforts to maintain the
effectiveness of the registration statement(s) described in Section 3.3(c) for
so long as the Empire Stock Options to be converted under the terms of the
Merger Agreement to options to purchase shares of Huntington Common remain
outstanding.


                                    ARTICLE 7
                CONDITIONS PRECEDENT TO OBLIGATIONS TO CONSUMMATE

         7.1  CONDITIONS TO OBLIGATIONS OF EACH PARTY. The respective
obligations of each Party to perform this Agreement and consummate the Merger
and the other transactions contemplated by the Merger Documents are subject to
the satisfaction of the following conditions, unless waived by both Parties
pursuant to Section 10.6 of this Agreement:

         (a)  Shareholder Approval. The shareholders of Empire shall have
approved this Agreement, and the consummation of the transactions contemplated
by the Merger Documents, including the Merger, as and to the extent required by
Law and by the provisions of its Governing Documents.

         (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 by the Merger Documents shall be conditioned or
restricted in a manner (including requirements relating to the raising of
additional capital or the disposition of Assets) which in the reasonable
judgment of either Party would so materially adversely impact the economic or
business benefits of the transactions contemplated by the Merger Documents so as
to render inadvisable the consummation of the Merger.

         (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 7.1(b) of this Agreement) or for the preventing of any Default under
any Contract or Permit of such Party





                                       62

<PAGE>   50

which, if not obtained or made, is reasonably likely to have, individually or in
the aggregate, a Material Adverse Effect on such Party. No Consent so obtained
which is necessary to consummate the transactions contemplated by the Merger
Documents shall be conditioned or restricted in a manner which in the reasonable
judgment of either Party would so materially adversely impact the economic or
business benefits of the transactions contemplated by the Merger Documents so as
to render inadvisable the consummation of the Merger.

         (d)  Legal Proceedings. No court or governmental authority 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 the Merger
Documents.

         (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 Huntington Common issuable pursuant to the Merger shall have been
received.

         (f)  Nasdaq  National  Market Listing. The shares of Huntington  Common
issuable pursuant to the Merger shall have been approved for quotation on the
Nasdaq National Market.

         (g)  Tax Matters. Each Party shall have received a written opinion of
counsel from Huntington's Counsel, in form reasonably satisfactory to such
Parties and dated as of the Effective Time (the "Tax Opinion"), to the effect
that (A) the Merger will constitute a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code, (B) the exchange in the Merger of
shares of Empire Common for shares of Huntington Common will not give rise to
gain or loss to the shareholders of Empire with respect to such exchange (except
to the extent of any cash received), and (C) neither Empire nor Huntington will
recognize gain or loss as a consequence of the Merger. Huntington shall also
cause Huntington's Counsel to provide such tax opinion(s) as are required to be
filed with the SEC as an exhibit to the Registration Statement, and any
amendments thereto. In rendering such opinions, such counsel shall be entitled
to rely upon representations of Empire's officers, directors, and shareholders
holding in excess of five percent (5%) of the outstanding shares of Empire
Common and representations of officers of Huntington, in each case reasonably
satisfactory in form and substance to such counsel.

         7.2  CONDITIONS TO OBLIGATIONS OF HUNTINGTON. The obligations of
Huntington to perform this Agreement and consummate the Merger and the other
transactions contemplated by the Merger Documents are subject to the
satisfaction of the following conditions, unless waived by Huntington pursuant
to Section 10.6(a) of this Agreement:

         (a)  Representations and Warranties. The representations and warranties

         9.1  TERMINATION. Notwithstanding any other provision of this
Agreement, and notwithstanding the approval of the Merger Documents by the
shareholders of Empire, this Agreement may be terminated and the Merger
abandoned at any time prior to the Effective Time:

         (a)  By mutual consent of the respective Boards of Directors of
Huntington and Empire;

         (b)  By the Board of Directors of either Party (provided that the
terminating Party is not then in material breach of any representation,
warranty, covenant, or other agreement contained in this Agreement) in the event
of the inaccuracy of any representation or warranty contained in this Agreement
of the other Party which cannot be or has not been cured within 30 days after
the giving written notice to such other 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 7.2(a)
of this Agreement in the case of any termination by Huntington and Section
7.3(a) of this Agreement in the case of any termination by Empire;

         (c)  By the Board of Directors of either Party (provided that the

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;

and the transactions contemplated by the Merger Documents as required by the
Laws of the State of Michigan, or by Empire's Governing Documents, at the

         (e)  By the Board of Directors of either Party in the event that the
Merger shall not have been consummated by January 31, 2001, if the failure to
consummate the transactions contemplated by the Merger Documents on or before
such date is not caused by any breach of this Agreement by the Party electing to
terminate pursuant to this Section 9.1(e);

         (f)  By the Board of Directors of either Party (provided that the
terminating Party is not then in material breach of any representation,
warranty, 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 9.1(e) of this Agreement; or

         (g)  By Huntington, in the event that the Board of Directors of Empire
fails to recommend to the shareholders of Empire that they vote their shares of
Empire Common in favor of the Merger, or withdraws such recommendation
previously made, or fails to solicit proxies of shareholders of Empire to
approve the Merger, or shall have affirmed, recommended, or authorized entering
into any Acquisition Transaction or other transaction involving a merger, share
exchange, consolidation, or transfer of substantially all of the Assets of
Empire.

Merger Agreement and this Agreement shall become void and have no effect, except
that (A) the provisions of this Section 9.2 and Articles 1 and 10 and Section
4.6(b) of this Agreement shall survive any such termination and abandonment, and
(B) a termination pursuant to Sections 9.1(b), (c), (d), (f), or (g) of this
Agreement shall not relieve the breaching Party from Liability for an uncured
willful breach of a representation, warranty, covenant, or agreement giving rise
to such termination. Upon a termination of this Agreement, the Warrant and the
Warrant Purchase Agreement shall terminate in accordance with the express
provisions of those documents.

(1) a certain Agreement and Plan of Merger, dated as of the date hereof (the
"Merger Agreement"), which provides for the merger of Empire into Huntington
(the "Merger"), and (2) a certain Supplemental Agreement, dated as of the date

to issue to Huntington a warrant or warrants entitling Huntington to purchase up
to a total of 630,080 shares of Empire Common, on the terms and conditions set

Price"), subject to adjustments as provided in the Warrant. (The holder of the
Warrant from time to time is referred to as the "Holder.") The Warrant shall be
exercisable in accordance with the terms and conditions set forth in this
Agreement.

         SECTION 2. REGISTRATION RIGHTS. If, at any time after the Warrant
becomes exercisable in accordance with its terms, Empire shall receive a written
request therefor from the Holder, Empire shall prepare and file a registration
statement under the 1933 Act covering


                                       73

<PAGE>   61


such number of shares of Empire Common as the Holder shall specify in the
request and shall use its best efforts to cause such registration statement to
become effective; provided, however, that the Holder shall only have the right
to request three such registrations. Without the written consent of the Holder,
neither Empire nor any other holder of securities of Empire may include any
other securities in such registration.

         SECTION 3.  "PIGGYBACK" RIGHTS. If, at any time after the Warrant
becomes exercisable in accordance with its terms, Empire shall determine to
proceed with the preparation and filing of a registration statement under the
1933 Act in connection with the proposed offer and sale for money of any of its
securities (other than in connection with a dividend reinvestment, employee
stock purchase, stock option, or similar plan or a registration statement on
Form S-4) by it or any of its security holders, Empire shall give written notice
thereof to the Holder. Upon the written request of the Holder given within ten
days after receipt of any such notice from Empire, Empire shall, except as
herein provided, cause all shares of Empire Common which the Holder shall
request be included in such registration statement to be so included; provided,
however, that nothing herein shall prevent Empire from abandoning or delaying
any registration at any time; and provided, further, that if Empire decides not
to proceed with a registration after the registration statement has been filed
with the SEC and Empire's decision not to proceed is primarily based upon the
anticipated public offering price of the securities to be sold by Empire, Empire
shall promptly complete the registration for the benefit of the Holder if the
Holder agrees to bear all additional and incremental expenses incurred by Empire
as the result of such registration after Empire has decided not to proceed. If
any registration pursuant to this Section shall be underwritten in whole or in
part, the Holder may require that any shares of Empire Common requested for
inclusion pursuant to this Section be included in the underwriting on the same
terms and conditions as the securities otherwise being sold through the
underwriters. In the event that the shares of Empire Common requested for
inclusion pursuant to this Section would constitute more than 25 percent of the
total number of shares to be included in a proposed underwritten public
offering, and if in the good faith judgment of the managing underwriter of such
public offering the inclusion of all of such shares would interfere with the
successful marketing of the shares of being offered by Empire, the number of
shares otherwise to be included in the underwritten public offering hereunder
may be reduced; provided, however, that after any such required reduction, the
shares of Empire Common to be included in such offering for the account of the
Holder shall constitute at least 25 percent of the total number of shares to be
included in such offering.

         SECTION 4.  OBLIGATIONS OF EMPIRE IN CONNECTION WITH A REGISTRATION. If
and whenever  Empire is required by the  provisions of Sections 2 or 3 hereof to
effect the registration of any shares of Empire Common under the 1933 Act,
Empire shall:

                 (a) prepare and file with the SEC a registration statement
with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for such period as may be
reasonably necessary to effect the sale of such securities, not to exceed nine
months;



                                       74




<PAGE>   62
              (b)   prepare and file with the SEC such amendments to such
registration statement and supplements to the prospectus contained therein as
may be necessary to keep such registration statement effective for such period
as may be reasonably necessary to effect the sale of such securities, not to
exceed nine months;

              (c)   furnish to the Holder and to the underwriters of the
securities being registered such reasonable number of copies of the registration
statement, amendments thereto, preliminary prospectus, final prospectus, and
such other documents as the Holder or such underwriters may reasonably request
in order to facilitate the public offering of such securities;

              (d)   use its best efforts to register or qualify the securities
covered by such registration statement under such state securities or blue sky
laws of such jurisdictions as the Holder or such underwriters may reasonably
request; provided that Empire shall not be required by virtue hereof to submit
to the general jurisdiction of any state;

              (e)   notify the Holder, promptly after Empire shall receive
notice thereof, of the time when such registration statement or any
post-effective amendment thereof has become effective or a supplement to any
prospectus forming a part of such registration statement has been filed;

              (f)   notify the Holder promptly of any request by the SEC for the
amending or supplementing of such registration statement or prospectus or for
additional information;

              (g)   prepare and file with the SEC, promptly upon the request of
the Holder, any amendments or supplements to such registration statement or
prospectus which, in the opinion of counsel for the Holder (and concurred in by
counsel for Empire), is required under the 1933 Act or the rules and regulations
promulgated thereunder in connection with the distribution of the shares of
Empire Common by the Holder;

              (h)   prepare and promptly file with the SEC such amendment or
supplement to such registration statement or prospectus as may be necessary to
correct any statements or omissions if, at the time when a prospectus is
required to be delivered under the 1933 Act, any event shall have occurred as
the result of which such prospectus as then in effect would include an untrue
statement of a material fact or omit to state any material fact necessary to
make the statements therein, in the light of the circumstances in which they
were made, not misleading;

              (i)   advise the Holder, promptly after it shall receive notice or
obtain knowledge thereof, of the issuance of any stop order by the SEC
suspending the effectiveness of such registration statement or the initiation or
threatening of any proceeding for that purpose and promptly use its best efforts
to prevent the issuance of any stop order or to obtain its withdrawal if such
stop order should be issued; and


                                       75


<PAGE>   63


              (j)   at the request of the Holder, furnish on the date or dates
provided for in the underwriting agreement: (1) an opinion or opinions of the
counsel representing Empire for the purposes of such registration, addressed to
the underwriters and to the Holder, covering such matters as such underwriters
and the Holder may reasonably request and as are customarily covered by issuer's
counsel at that time; and (2) a letter or letters from the independent certified
public accountants of Empire, addressed to the underwriters and to the Holder,
covering such matters as such underwriters or the Holder may reasonably request,
in which letters such accountants shall state (without limiting the generality
of the foregoing) that they are independent certified public accountants within
the meaning of the 1933 Act and that, in the opinion of such accountants, the
financial statements and other financial data of Empire included in the
registration statement or any amendment or supplement thereto comply in all
material respects with the applicable accounting requirements of the 1933 Act.

         SECTION 5. EXPENSES OF REGISTRATION. With respect to a registration
requested pursuant to Section 2 hereof and with respect to each inclusion of
shares of Empire Common in a registration statement pursuant to Section 3
hereof, Empire shall bear the following fees, costs, and expenses: all
registration, stock exchange listing or NASD fees, printing expenses, fees and
disbursements of counsel and accountants for Empire, fees and disbursements of
counsel for the underwriter or underwriters of such securities (if Empire and/or
the Holder are required to bear such fees and disbursements), and all legal fees
and disbursements and other expenses of complying with state securities or blue
sky laws of any jurisdictions in which the securities to be offered are to be
registered or qualified. Fees and disbursements of counsel and accountants for
the Holder, underwriting discounts and commissions and transfer taxes relating
to the Empire Common being sold for the Holder, and any other expenses incurred
by the Holder not expressly included above shall be borne by the Holder.

         SECTION 6. INDEMNIFICATION.

              (a)   Empire shall indemnify and hold harmless the Holder, any
underwriter (as defined in the 1933 Act) for the Holder, and each person, if
any, who controls the Holder or such underwriter within the meaning of the 1933
Act, from and against any and all loss, damage, liability, cost, and expense to
which the Holder or any such underwriter or controlling person may become
subject under the 1933 Act or otherwise, insofar as such losses, damages,
liabilities, costs, or expenses are caused by any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
filed pursuant to Section 4 hereof, any prospectus or preliminary prospectus
contained therein, or any amendment or supplement thereto, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they are made, not misleading; provided,
however, that Empire will not be liable in any such case to the extent that any
such loss, damage, liability, cost, or expense arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission so
made in conformity with information furnished by the Holder, such underwriter,
or such controlling persons in writing specifically for use in the preparation
thereof.


                                       76


<PAGE>   64


              (b)   Promptly after receipt by an indemnified party pursuant to
the provisions of paragraph (a) of this Section 6 of notice of the commencement
of any action involving the subject matter of the foregoing indemnity
provisions, such indemnified party shall, if a claim thereof is to be made
against Empire pursuant to the provision of such paragraph (a), promptly notify
Empire of the commencement thereof; but the omission to so notify Empire will
not relieve it from any liability which it may have to any indemnified party
otherwise hereunder. In case such action is brought against any indemnified
party and such indemnified party notifies Empire of the commencement thereof,
Empire shall have the right to participate in and, to the extent that it may
wish to do so, to assume the defense thereof, with counsel satisfactory to such
indemnified party; provided, however, if the defendants in any action include
both the indemnified party and Empire and there is a conflict of interest which
would prevent counsel for Empire from also representing the indemnified party,
the indemnified party or parties shall have the right to select one separate
counsel to participate in the defense of such action on behalf of such
indemnified party or parties. After notice from Empire to such indemnified party
of its election so to assume the defense of any such action, the indemnified
party shall have the right to participate in such action and to retain its own
counsel, but Empire shall not be required to indemnify and hold harmless the
indemnified party pursuant to the provisions of such paragraph (a) for any legal
fees or other expenses subsequently incurred by such indemnified party in
connection with the defense thereof, other than reasonable costs of
investigation, unless (1) the indemnified party shall have employed separate
counsel in accordance with the provisions of the preceding sentence of this
paragraph (b), (2) Empire shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after the notice of the commencement of the action, or (3) Empire has authorized
the employment of counsel for the indemnified party at the expense of Empire.

              (c)   If recovery is not available under the foregoing
indemnification provisions, for any reason other than as specified therein, the
parties entitled to indemnification by the terms thereof shall be entitled to
contribution to liabilities and expenses, except to the extent that contribution
is not permitted under Section 11(f) of the 1933 Act. In determining the amount
of contribution to which the respective parties are entitled, there shall be
considered the parties' relative knowledge and access to information concerning
the matter with respect to which the claim was asserted, the opportunity to
correct and prevent any statement or omission, and any other equitable
considerations appropriate under the circumstances.

         SECTION 7. REPURCHASE RIGHTS.

              (a)   At any time after the Warrant becomes exercisable and prior
to the expiration of the Warrant, in accordance with the terms thereof:

                    (1)   Empire may, and upon the written request of the
         Holder, Empire shall, repurchase the Warrant from the Holder at a price
         (the "Warrant



                                       77


<PAGE>   65



         Repurchase Price") equal to the difference between the "Market/Offer
         Price" (as defined in paragraph (b) below) and the Exercise Price,
         multiplied by the number of shares for which the Warrant may then be
         exercised, in the aggregate, but only if the Market/Offer Price is
         greater than the Exercise Price; and

                    (2)   Empire may, and upon the written request of the owner
     (the "Owner") of any shares of Empire Common purchased pursuant to an
     exercise of the Warrant ("Warrant Stock"), Empire shall, repurchase all of
     the shares of Warrant Stock held by such Owner at a price (the "Warrant
     Stock Repurchase Price") equal to the number of shares to be repurchased
     hereunder multiplied by the greater of the Exercise Price and the
     Market/Offer Price.

            (b)     For purposes of Section 7(a), the "Market/Offer Price" shall
mean the highest of (1) the price per share at which a tender offer or exchange
offer for shares of Empire Common has been made, (2) the price per share of
Empire Common to be paid by any third party pursuant to an agreement with
Empire, and (3) the highest closing price for shares of Empire Common within the
4-month period immediately preceding the date the Holder gives notice of the
required repurchase of the Warrant or the Owner gives notice of the required
repurchase of Warrant Stock, as appropriate. In the event that an exchange offer
is made or an agreement is entered into for a merger or consolidation involving
consideration other than cash, the value of the securities or other property
issuable or deliverable in exchange for Empire Common shall be determined by a
nationally recognized investment banking firm mutually acceptable to the parties
hereto.

            (c)     The Holder and the Owner may exercise their respective
rights to require Empire to repurchase the Warrant or the Warrant Stock pursuant
to this Section 7 by surrendering for such purpose to Empire, at its principal
office, the Warrant or certificates for shares of Warrant Stock, as the case may
be, free and clear of any liens, claims, encumbrances, or rights of third
parties of any kind, accompanied by a written notice or notices stating that the
Holder or the Owner, as the case may be, requests Empire to repurchase such
Warrant or Warrant Stock in accordance with the provisions of this Section 7.
Subject to the last proviso of Section 7(d) below, as promptly as practicable,
and in any event within five business days after the surrender of the Warrant or
certificates representing shares of Warrant Stock and the receipt of such notice
or notices relating thereto, Empire shall deliver or cause to be delivered to
the Holder or Owner the Warrant Repurchase Price or the Warrant Stock Repurchase
Price therefor, as applicable, or the portion thereof which Empire is not then
prohibited under applicable law and regulation from so delivering.

                    (d) To the extent that Empire is prohibited under applicable
     law or regulation, or as a result of administrative or judicial action,
     from repurchasing the Warrant and/or the Warrant Stock in full at any time
     that it may be required to do so hereunder, Empire shall immediately so
     notify the Holder and/or the Owner and thereafter deliver or cause to be
     delivered, from time to time, to the Holder and/or the Owner, as
     appropriate, the portion of the Warrant Repurchase Price and the Warrant
     Stock Repurchase Price, respectively, which it is no longer prohibited from
     delivering, within five business days after the date on which Empire is no
     longer so prohibited. Upon receipt of such notice from Empire and for a
     period of 15 days thereafter, the Holder and/or Owner may revoke its notice
     of repurchase of the Warrant and/or Warrant Stock by written notice to
     Empire at its principal office stating that the


                                       78


<PAGE>   66



     Holder and/or the Owner elects to revoke its election to exercise its right
     to require Empire to repurchase the Warrant and/or Warrant Stock, whereupon
     Empire will promptly deliver to the Holder and/or Owner the Warrant and/or
     certificates representing shares of Warrant Stock surrendered to Empire for
     purposes of such repurchase. Whether or not such election is revoked,
     Empire hereby agrees to use its best efforts to obtain all required legal
     and regulatory approvals necessary to permit Empire to repurchase the
     Warrant and/or the Warrant Stock as promptly as practicable.

         SECTION 8.  ASSUMPTION OF OBLIGATIONS UNDER THIS AGREEMENT. Empire will
not enter into any transaction described in Section 5(a) of the Warrant unless
the "Acquiring Corporation" (as that term is defined in the Warrant) assumes in
writing all the obligations of Empire hereunder.

         SECTION 9.  REMEDIES. Without limiting the foregoing or any remedies
available to the Holder, Empire specifically acknowledges that neither
Huntington nor any successor holder of the Warrant would have an adequate remedy
at law for any breach of this Warrant Purchase Agreement and Empire hereby
agrees that Huntington and any successor holder of the Warrant shall be entitled
to specific performance of the obligations of Empire hereunder and injunctive
relief against actual or threatened violations of the provisions hereof.

         SECTION 10. TERMINATION. This Agreement will terminate upon a
termination of the Warrant in accordance with Section 9 thereof.

         IN WITNESS WHEREOF, the parties hereto have executed this Warrant
Purchase Agreement as of the day and year first above written.

THIS WARRANT AND THE COMMON SHARES ISSUABLE UPON THE EXERCISE HEREOF HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR REGISTERED OR
QUALIFIED UNDER ANY STATE SECURITIES LAWS, AND MAY NOT BE SOLD OR OTHERWISE
TRANSFERRED WITHOUT BEING SO REGISTERED OR QUALIFIED UNLESS AN EXEMPTION OR

                                     WARRANT

                        TO PURCHASE 630,080 COMMON SHARES

                                       OF

                             EMPIRE BANC CORPORATION


         This is to certify that, for value received, HUNTINGTON BANCSHARES
INCORPORATED, a Maryland corporation ("Huntington"), is entitled to purchase
from EMPIRE BANC CORPORATION, a Michigan corporation ("Empire"), at any time on
or after the date hereof, an aggregate of up to 630,080 common shares, without
par value, of Empire ("Empire Common"), at a price of $29.00 per share (the
"Exercise Price"), subject to the terms and conditions of this Warrant and a
certain Warrant Purchase Agreement, of even date herewith, between Huntington
and Empire (the "Warrant Purchase Agreement"). The number of shares of Empire
Common which may be received upon the exercise of this Warrant and the Exercise
Price are subject to adjustment from time to time as hereinafter set forth. The
terms and conditions set forth in this Warrant and the Warrant Purchase
Agreement shall be binding upon the respective successors and assigns of both of
the parties hereto. This Warrant is issued in connection with a certain
Agreement and Plan of Merger, dated as of the date hereof, between Huntington
and Empire (the "Merger Agreement"), which provides for the merger of Empire
into Huntington (the "Merger"), and a certain Supplemental Agreement between
Huntington and Empire, which provides certain additional terms and conditions
relating to the Merger (the "Supplemental Agreement"). (The Merger Agreement and
the Supplemental Agreement are sometimes hereinafter collectively referred to as
the "Merger Documents.") All capitalized terms used herein and not otherwise
defined herein shall have the meanings ascribed to them in the Merger Documents.
The term "Holder" shall mean and refer to Huntington or any successor holder of
this Warrant.

         SECTION 1.     EXERCISE OF THE WARRANT.

                 (a)    The Holder will not exercise this Warrant unless it has
obtained all required approvals, if any, of appropriate regulatory authorities
having jurisdiction, including the Federal Reserve Board, pursuant to all
applicable laws and regulations. Further, subject to the terms and conditions
set forth in this Warrant and in the Warrant Purchase Agreement and the
provisions of applicable law, the Holder will not exercise this Warrant without
the written consent of Empire except upon the occurrence of any of the following
events (a "Triggering Event"):

         (1)     any material, willful, and intentional breach of the Merger
                 Documents by Empire that would permit Huntington to terminate
                 the Merger Documents (A) occurring after the receipt by Empire
                 after February 4, 2000, of a proposal to engage in an
                 Acquisition Transaction, (B) occurring after the announcement
                 by any other Person of an intention to engage in an Acquisition
                 Transaction, or (C) in anticipation and for the purpose of
                 engaging in an Acquisition Transaction;

         (2)     (A) a proposal to engage in an Acquisition Transaction is
                 submitted to and approved by the shareholders of Empire at any
                 time prior to January 31, 2001, or (B) a Tender Offer is
                 commenced and the transactions contemplated in the Tender Offer
                 are completed in such a manner that the Person making the
                 Tender Offer acquires beneficial ownership of more than 20
                 percent of the capital stock or any other class of voting
                 securities of Empire, and the Merger is not consummated prior
                 to January 31, 2001; or

         (3)     (A) a proposal to engage in an Acquisition Transaction is
                 received by Empire after February 4, 2000, or a Tender Offer is
                 made directly to the shareholders of Empire or the intention of
                 making an Acquisition Transaction or a Tender Offer is
                 announced at any time prior to the holding of the Empire
                 Shareholders' Meeting; (B) the Board of Directors of Empire (1)
                 fails to recommend to the shareholders of Empire that they vote
                 their shares of Empire Common in favor of the approval of the
                 Merger, (2) withdraws such recommendation previously made, (3)
                 fails to solicit proxies of shareholders of Empire to approve
                 the Merger, or (4) fails to hold the Empire Shareholders'
                 Meeting; and (C) the Merger is not consummated by January 31,
                 2001.

                 (b)   Notwithstanding the foregoing, this Warrant shall not be
exercisable in the event of the failure to consummate the Merger solely as a
result of any of the following: (1) the failure of any Regulatory Authority to
provide any required Consent to the Merger, which failure was not the result of
the existence of the Acquisition Proposal or a breach by Empire of any of its
obligations under any of the Merger Documents; or (2) the Merger



                                       81




<PAGE>   69


Documents are terminated pursuant to Section 9.1 of the Supplemental Agreement,
unless the event giving rise to the right to terminate is preceded by a
Triggering Event or the receipt by Empire after February 4, 2000, of an
Acquisition Transaction proposal, or the announcement by another Person of a
proposal involving an Acquisition Transaction. For purposes of this Section 1, a
Tender Offer which is contingent upon the expiration of the Warrant is deemed to
commence when it is announced. Empire represents to the Holder that, except with
respect to the Merger Documents, there are no proposals or offers to engage in
an Acquisition Transaction previously received by Empire which remain
outstanding as of the close of business on February 4, 2000. Any breach of this
representation by Empire will cause any such proposal or offer, whether in its
original form or as amended, to be deemed to be received by Empire after
February 4, 2000, for purposes of this Section 1.

                 (c)   This Warrant shall be exercised by presentation and
surrender hereof to Empire at its principal office accompanied by (1) a written
notice of exercise for a specified number of shares of Empire Common, (2)
payment to Empire, for the account of Empire, of the Exercise Price for the
number of shares specified in such notice, and (3) a certificate of the Holder
indicating the Triggering Event that has occurred which entitles the Holder to
exercise this Warrant. The Exercise Price for the number of shares of Empire
Common specified in the notice shall be payable in immediately available funds.

                 (d)   Upon such presentation and surrender, Empire shall issue
promptly (and within three business days if requested by the Holder) to the
Holder, or any assignee, transferee, or designee permitted by Section 1(f), the
shares to which the Holder is entitled hereunder.

                 (e)   If this Warrant should be exercised in part only, Empire
shall, upon surrender of this Warrant for cancellation, execute and deliver a
new Warrant evidencing the rights of the Holder thereof to purchase the balance
of the shares purchasable hereunder. Upon receipt by Empire of this Warrant, in
proper form for exercise, the Holder shall be deemed to be the holder of record
of the shares of Empire Common issuable upon such exercise, notwithstanding that
the stock transfer books of Empire shall then be closed or that certificates
representing such shares of Empire Common shall not then be actually delivered
to the Holder. Empire shall pay all expenses, and any and all federal, state,
and local taxes and other charges that may be payable in connection with the
preparation, issue, and delivery of stock certificates under this Section 1 in
the name of the Holder or of any assignee, transferee, or designee permitted by

         SECTION 2.    CERTAIN COVENANTS AND REPRESENTATIONS OF EMPIRE.

                 (a)   Empire shall at all times maintain sufficient authorized
but unissued shares of Empire Common so that this Warrant may be exercised
without additional authorization of the holders of Empire Common, after giving
effect to all other options, warrants, convertible securities, and other rights
to purchase Empire Common.

                 (b)   Empire represents and warrants to the Holder that the
shares of Empire Common issued upon an exercise of this Warrant will be duly
authorized, fully paid, non-assessable, and subject to no preemptive rights.

                 (c)   Empire agrees (1) that it will not, by charter amendment
or through reorganization, consolidation, merger, dissolution, or sale of
assets, or by any other voluntary act, avoid or seek to avoid the observance or
performance of any of the covenants, stipulations, or conditions to be observed
or performed hereunder by Empire; (2) promptly to take all action as may from
time to time be required, including, without limitation (A) complying with all
pre-merger notification, reporting, and waiting period requirements specified in
15 U.S.C. ss.18a and regulations promulgated thereunder, and (B) in the event,
under the Bank Holding Company Act of 1956, as amended (the "Bank Holding
Company Act"), or the Change in Bank Control Act of 1978, or other statute, the
prior approval of the Federal Reserve Board or other regulatory agency
(collectively, the "Agencies"), is necessary before the Warrant may be exercised
or transferred, cooperate fully with the Holder in preparing such applications
and providing such information to the Agencies as the Agencies may require in
order to permit the Holder to exercise or transfer this Warrant and Empire duly
and effectively to issue shares pursuant to the exercise hereof; and (3)
promptly to take all action provided herein to protect the rights of the Holder
against dilution.

         SECTION 3.    FRACTIONAL SHARES. Empire shall not be required to issue
fractional shares of Empire Common upon an exercise of this Warrant but shall
pay for such fraction of a share in cash or by certified or official bank check
at the Exercise Price.

         SECTION 4.    EXCHANGE OR LOSS OF WARRANT. This Warrant is
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender hereof at the principal office of Empire for other Warrants of
different denominations entitling the Holder thereof to purchase in the
aggregate the same number of shares of Empire Common purchasable hereunder. The
term "Warrant" as used herein includes any warrants for which this Warrant may
be exchanged. Upon receipt by Empire of evidence reasonably satisfactory to it
of the loss, theft, destruction, or mutilation of this Warrant, and (in the case
of loss, theft, or destruction) of reasonably satisfactory indemnification, and
upon surrender and cancellation of this Warrant, if mutilated, Empire will
execute and deliver a new Warrant of like tenor and date. Any such new Warrant
executed and delivered shall constitute an additional contractual obligation on
the part of Empire, whether or not the Warrant so lost, stolen, destroyed, or
mutilated shall at any time be enforceable by anyone.

         SECTION 5.    CERTAIN TRANSACTIONS.

                 (a)   In case Empire shall (1) consolidate with or merge into
any Person, other than Huntington or one of its Affiliates, and shall not be the
continuing or surviving corporation of such consolidation or merger, (2) permit
any Person, other than Huntington or one of its Affiliates, to merge into Empire
and Empire shall be the continuing or surviving corporation, but, in connection
with such merger, the then outstanding shares of Empire Common shall be changed
into or exchanged for stock or other securities of any other Person or cash or
any other property, or (3) sell or otherwise transfer all or substantially all
of its assets to any Person, other than Huntington or one of its Affiliates,
then, and in any such case, the agreement governing such transaction shall make
proper provision so that this Warrant shall, upon the consummation of any such
transaction and upon the terms and conditions set forth herein, be converted
into, or exchanged for, a warrant, at the option of the Holder, of either (A)
the Acquiring Corporation (as hereinafter defined), (B) any company which
controls the Acquiring Corporation, or (C) in the case of a merger described in
clause (a)(2) above, Empire, in which case such warrant shall be a newly issued
warrant (in any such case, the "Substitute Warrant").

                 (b)   For purposes of this Section 5, the following terms have
the meanings indicated:

                       (1) "Acquiring Corporation" shall mean (A) the continuing
         or surviving corporation of a consolidation or merger with Empire (if
         other than Empire), (B) the corporation merging into Empire in a merger
         in which Empire is the continuing or surviving person and in connection
         with which the then outstanding shares of Empire Common are changed
         into or exchanged for stock or other securities of any other Person or
         cash or any other property, or (C) the transferee of all or
         substantially all of Empire's assets;

                       (2) "Substitute Common" shall mean the common stock
         issued by the issuer of the Substitute Warrant;

                       (3) "Assigned Value" shall mean the Market/Offer Price as
         determined pursuant to paragraph 7(b) of the Warrant Purchase
         Agreement; provided, however, that in the event of a sale of all or
         substantially all of Empire's assets, the Assigned Value shall be the
         sum of the price paid in such sale for such assets and the current
         market value of the remaining assets of Empire as determined by a
         recognized investment banking firm selected by the Holder, divided by
         the number of shares of Empire Common outstanding at the time of such
         sale;

                           (4) "Average Price" shall mean the average closing
         price of a share of Substitute Common for the one year immediately
         preceding the consolidation, merger, or sale in question, but in no
         event higher than the



                                       84





<PAGE>   72




         closing price of the shares of Substitute Common on the day preceding
         such consolidation, merger, or sale; provided that if Empire is the
         issuer of the Substitute Warrant, the Average Price shall be computed
         with respect to a share of the common stock issued by the Person
         merging into Empire or by any company which controls such Person, as
         the Holder may elect;

                       (5) A "Person" shall mean any individual, firm,
         corporation, or other entity and include as well any syndicate or group
         deemed to be a "person" by Section 13(d)(3) of the Securities Exchange
         Act of 1934, as amended; and

                       (6) "Affiliate" shall have the meaning ascribed to such
         term in Rule 12b-2 of the General Rules and Regulations under the
         Securities Exchange Act of 1934, as amended.

                 (c)   The Substitute Warrant shall have the same terms as this
Warrant, provided that, if the terms of the Substitute Warrant cannot, for legal
reasons, be the same as this Warrant, such terms shall be as similar as possible
and in no event less advantageous to the Holder. The issuer of the Substitute
Warrant shall also enter into an agreement with the then Holder of the
Substitute Warrant in substantially the same form as the Warrant Purchase
Agreement, which shall be applicable to the Substitute Warrant.

                 (d)   The Substitute Warrant shall be exercisable for such
number of shares of Substitute Common as is equal to the Assigned Value
multiplied by the number of shares of Empire Common for which this Warrant is
then exercisable, divided by the Average Price. The exercise price of the
Substitute Warrant per share of Substitute Common shall be equal to the Exercise
Price multiplied by a fraction in which the numerator is the number of shares of
Empire Common for which this Warrant is then exercisable and the denominator is
the number of shares of Substitute Common for which the Substitute Warrant is
exercisable.

         SECTION 6.    RIGHTS OF THE HOLDER; REMEDIES.

                 (a)   The Holder shall not, by virtue hereof and prior to the
exercise hereof, be entitled to any rights of a holder of Empire Common.

                 (b)   Without limiting the foregoing or any remedies available
to the Holder, Empire specifically acknowledges that neither Huntington nor any
successor Holder of this Warrant would have an adequate remedy at law for any
breach of this Warrant and Empire hereby agrees that Huntington and any
successor Holder shall be entitled to specific performance of the obligations of
Empire hereunder and injunctive relief against actual or threatened violations
of the provisions hereof.



                                       85




<PAGE>   73


         SECTION 7.   ANTIDILUTION PROVISIONS. The number of shares of Empire
    Common purchasable upon the exercise hereof shall be subject to adjustment
    from time to time as provided in this Section 7.

                 (a)  In the event that Empire issues any additional shares of
    Empire Common at any time after the date hereof (including pursuant to stock
    option plans), the number of shares of Empire Common which can be purchased
    pursuant to this Warrant shall be increased by an amount equal to 19.9
    percent of the additional shares so issued.

                 (b) (1)  In the event that, after the date hereof, Empire pays
    or makes a dividend or other distribution of any class of capital stock of
    Empire in Empire Common, the number of shares of Empire Common purchasable
    upon exercise hereof shall be increased by multiplying such number of shares
    by a fraction of which the denominator shall be the number of shares of
    Empire Common outstanding at the close of business on the day immediately
    preceding the date of such distribution and the numerator shall be the sum
    of such number of shares and the total number of shares constituting such
    dividend or other distribution, such increase to become effective
    immediately after the opening of business on the day following such
    distribution.

                     (2)  In the event that, after the date hereof, outstanding
    shares of Empire Common are subdivided into a greater number of shares of
    Empire Common, the number of shares of Empire Common purchasable upon
    exercise hereof at the opening of business on the day following the day upon
    which such subdivision becomes effective shall be proportionately increased,
    and, conversely, in the event that, after the date hereof, outstanding
    shares of Empire Common are combined into a smaller number of shares of
    Empire Common, the number of shares of Empire Common purchasable upon
    exercise hereof at the opening of business on the day following the day upon
    which such combination becomes effective shall be proportionately decreased,
    such increase or decrease, as the case may be, to become effective
    immediately after the opening of business on the day following the day upon
    which such subdivision or combination becomes effective.

                     (3) The reclassification (including any reclassification
    upon a merger in which Empire is the continuing corporation) of Empire
    Common into securities including other than Empire Common shall be deemed to
    involve a subdivision or combination, as the case may be, of the number of
    shares of Empire Common outstanding immediately prior to such
    reclassification into the number of shares of Empire Common outstanding
    immediately thereafter and the effective date of such reclassification shall
    be deemed to be the day upon which such subdivision or combination becomes
    effective, as the case may be, within the meaning of clause (2) above.

                 (c)  Whenever the number of shares of Empire Common purchasable
    upon exercise hereof is adjusted pursuant to paragraph (b) above, the
    Exercise Price shall be adjusted by multiplying the Exercise Price by a
    fraction the numerator of which is equal to the number of shares of Empire
    Common purchasable prior to the adjustment and the denominator of which is
    equal to the number of shares of Empire Common purchasable after the
    adjustment.

<PAGE>   74


                 (d)  For the purpose of this Section 7, the term "Empire
    Common" shall include any shares of Empire of any class or series which has
    no preference or priority in the payment of dividends or in the distribution
    of assets upon any voluntary or involuntary liquidation, dissolution, or
    winding up of Empire and which is not subject to redemption by Empire.

    SECTION 8.   NOTICE.

                 (a)  Whenever the number of shares of Empire Common for which
    this Warrant is exercisable is adjusted as provided in Section 7 hereof,
    Empire shall promptly compute such adjustment and mail to the Holder a
    certificate, signed by a principal financial officer of Empire, setting
    forth the number of shares of Empire Common for which this Warrant is
    exercisable and the adjusted Exercise Price as a result of such adjustment,
    a brief statement of the facts requiring such adjustment, the computation
    thereof, and when such adjustment will become effective.

                 (b)  Upon the occurrence of a Triggering Event, Empire shall
    (1) promptly notify the Holder and/or the "Owner" (as that term is defined
    in the Warrant Purchase Agreement) of such event, (2) promptly compute the
    "Warrant Repurchase Price" and the "Warrant Stock Repurchase Price" (as such
    terms are defined in the Warrant Purchase Agreement), and (3) furnish to the
    Holder and/or the Owner a certificate, signed by the chief financial officer
    of Empire setting forth the Warrant Repurchase Price and/or the Warrant
    Stock Repurchase Price and the basis and computation thereof.

                 (c)  Upon the occurrence of an event which results in this
    Warrant becoming convertible into, or exchangeable for, the Substitute
    Warrant, as provided in Section 5 hereof, Empire and the Acquiring
    Corporation shall promptly notify the Holder of such event; and, upon
    receipt from the Holder of its choice as to the issuer of the Substitute
    Warrant, the Acquiring Corporation shall promptly compute the number of
    shares of Substitute Common for which the Substitute Warrant is exercisable
    and furnish to the Holder a certificate, signed by a principal financial
    officer of the Acquiring Corporation, setting forth the number of shares of
    Substitute Common for which the Substitute Warrant is exercisable, the
    Substitute Warrant exercise price, a computation thereof, and when such
    adjustment will become effective.

         SECTION 9. TERMINATION. This Warrant and the rights conferred hereby
    shall terminate upon the earliest of (1) six months after the occurrence of
    a Triggering Event, (2) the Effective Date of the Merger, (3) the date of
    termination of the Merger Documents unless the event giving rise to the
    right to terminate is preceded by a Triggering Event or the receipt by
    Empire, or the announcement by another Person, of a proposal involving an
    Acquisition Transaction or Tender Offer, or (4) March 31, 2001.

         IN WITNESS WHEREOF, the undersigned has executed this Warrant as of
    this 4th day of February, 2000.

            HUNTINGTON BANCSHARES TO ACQUIRE EMPIRE BANC CORPORATION

         COLUMBUS, Ohio - Huntington Bancshares Incorporated (NASDAQ: HBAN;
www.huntington.com) and Empire Banc Corporation (OTC: EMBM) jointly announced
today they have signed a definitive agreement for Huntington to acquire Empire
Banc Corporation, a bank holding company headquartered in Traverse City,
Michigan.
         Empire Banc Corporation, with assets of $505.7 million and deposits of
$418.4 million, has 10 offices and 12 ATMs in northern Michigan. For the year
ended December 31, 1999, Empire Banc's net income was $7.3 million, with a
corresponding return on assets of 1.47% and a return on equity of 17.03%. Five
of the 10 offices to be purchased by Huntington are in Grand Traverse County;
the addition of these offices will increase Huntington's market share in that
county from seventh to second. Upon completion of the acquisition, Huntington
will have more than 130 banking offices, 200 ATMs, and 4.6 billion of deposits
in the state of Michigan.
         "This affiliation is an excellent opportunity for Huntington to acquire
market share in Michigan that complements our already strong presence in that
state," said Frank Wobst, chairman and chief executive officer of Huntington
Bancshares Incorporated. "We recently have been successful in improving our
efficiency and streamlining our operations, including moving to a
state-of-the-art operations facility, and now we're poised to grow. Huntington
is pleased to have found such an attractive partner in Empire Banc, whose strong
performance ratios and emphasis on high asset quality so closely match our own.
We have great respect for the banking franchise that three generations of the
Dutmers family have built and the role they've played in the development of the
area's economy."

         "This agreement is exciting because it represents a significant
opportunity to serve Empire's customers, who will benefit from the additional
breadth of products and services Huntington has to offer," said Bill Kleven,
president of Huntington's Northwest Region.
         Empire Banc shareholders will receive 2.0355 Huntington shares for each
share of Empire Banc in a tax-free exchange. This is equivalent to approximately
$43.25 per share based on Huntington's closing stock price on February 4, 2000.
The acquisition will be accounted for as a purchase and is expected to close by
the end of the second quarter of 2000. It is anticipated to be neutral to
earnings per share for 2000 and to be slightly accretive by 2001. Huntington
plans to issue approximately 6.5 million shares in connection with the
transaction, which are to be purchased on the open market.
         "The decision to change strategic direction was not easy, but we are
confident our choice of Huntington is the right one for all of our
constituencies - our employees, customers, and stockholders," said James E.
Dutmers, Jr., chief executive officer of Empire Banc Corporation. "We have had
the privilege of getting to know the management team at Huntington and believe
Huntington, with its customer and community focus, innovative technology,
diversity of businesses, and financial strength, is the ideal partner for us as
we prepare for the challenges and opportunities of the next century." Continued
Dutmers, "This affiliation with Huntington enhances shareholder value, as our
shareholders receive a significant increase in the value of their investment
through capital appreciation and cash dividends."
         Huntington Bancshares is a regional bank holding company headquartered
in Columbus, Ohio with assets of $29 billion.  The Huntington has more than 134
years of serving the financial needs of its customers.
         The Huntington provides innovative products and services through its
