ITEM 5. OTHER EVENTS.

         American Bancshares, Inc. a Florida corporation ("ABI"), American Bank
of Bradenton, a Florida state chartered bank and wholly-owned subsidiary of ABI
("American Bank"), and Murdock Florida Bank, a Florida state chartered bank
("Murdock"), have entered into an Agreement and Plan of Merger dated September
23, 1997, as amended on October 8, 1997 ("Merger Agreement"), pursuant to which,
among other things, Murdock will be merged with and into American Bank, with
American Bank as the surviving corporation (the "Merger"). A copy of the Merger
Agreement and the amendment thereto are attached hereto as Exhibits 2.1 and 2.2,
respectively, and are incorporated herein by reference. The press release
describing the proposed Merger is attached hereto as Exhibit 99.1.

         ABI is a Florida-based bank holding company registered under the Bank
Holding Company Act of 1956, as amended, with total assets of approximately
$256.7 million as of June 30, 1997. Pursuant to the terms of the Merger
Agreement, each share of Murdock common stock, $10.00 par value per share
("Murdock Common Stock") will be converted into 2.40 ("Exchange Ratio") ABI
common shares, $1.175 par value per share ("ABI Common Shares"). No fractional
ABI Common Shares will be issued in the Merger, and Murdock stockholders who
otherwise would be entitled to receive a fractional ABI Common Share will
receive a cash payment in lieu thereof. Outstanding options held by employees of
Murdock will be converted into ABI options at the same Exchange Ratio.

         If the average of the last daily sales price of ABI Common Shares as 
reported on Nasdaq for a specified period prior to closing ("ABI Average
Price") is less than $11.00, then the Exchange Ratio shall be increased to 2.65
(assuming that the Closing Equity, as defined in the Merger Agreement, of
Murdock is at least $5,000,000). If the Closing Equity is less than $5,000,000,
then the Exchange Ratio shall be adjusted to equal a purchase price of 2.33
times the Closing Equity based on an ABI Common Share price of $12.169 (or
$11.00 if the ABI Average Price is less than $11.00).

         The Merger is intended to be a tax-free reorganization under the
Internal Revenue Code of 1986, as amended, and to be accounted for under the
pooling of interest method.

         Consummation of the Merger is subject to a number of conditions,
including: (i) receipt of the affirmative approval of the Merger Agreement by at
least two-thirds of the outstanding shares of Murdock Common Stock, (ii) receipt
of all requisite governmental and regulatory approvals (including approval of
the Florida Department of Banking and Finance and the Board of Governors of the
Federal Reserve System), (iii) Murdock's receipt of a fairness opinion from its
investment banker within five days from the date of its proxy statement, (iv)
effectiveness of a registration statement to be filed by ABI with the Securities
and Exchange Commission ("SEC") with respect to the ABI Common Shares to be
issued in the Merger, (v) receipt of a letter from ABI's independent public
accountants that the Merger will be accounted for as a pooling of interests,
(vi) receipt of a favorable opinion of counsel with respect to the tax free
nature of certain aspects of the Merger, and (vii) the satisfaction of certain
other closing conditions customary in a transaction of this type. The Merger
Agreement provides that American Bank will establish after the Merger an
Advisory Board of Directors for its Murdock branch which will include up to
three current members of the Murdock Board of Directors. The Merger Agreement
is subject to termination under certain circumstances, including the failure to
consummate the Merger by April 30, 1998. In addition, in the event that the
ABI Average Price is less than $10.00 or the Closing Equity is less than
$4,875,000, then the parties must attempt to negotiate in good faith a mutually
acceptable purchase price for the Murdock Common Stock. If the parties are
unable to do so, then Murdock shall have the right to terminate the Merger
Agreement in the case of an ABI Average Price of less than $10.00, and ABI

shall have the right to terminate the Merger Agreement in the case of a Closing
Equity of less than $4,875,000.

         The foregoing summary of the contents of the Merger Agreement is
qualified in its entirety by reference to Exhibits 2.1 and 2.2.

         On September 24, 1997, ABI announced the execution of the definitive
Merger Agreement with Murdock and its general terms.

                          AGREEMENT AND PLAN OF MERGER


         AGREEMENT AND PLAN OF MERGER (this "Agreement") dated as of September
23, 1997 by and among AMERICAN BANCSHARES, INC. ("ABI"), a Florida corporation
having its principal office located in Bradenton, Florida, AMERICAN BANK OF
BRADENTON ("American Bank"), a Florida state chartered bank, and MURDOCK FLORIDA
BANK ("Murdock"), a Florida state chartered bank having its principal office
located in Murdock, Florida.

                                    PREAMBLE

         The Boards of Directors of ABI, American Bank, and Murdock are of the
opinion that the transactions described herein are in best interest of the
parties and their respective shareholders and have approved the transactions
described herein. This Agreement provides for the acquisition of Murdock by ABI
pursuant to the merger of Murdock with and into, American Bank (the "Merger"), a
wholly owned subsidiary of ABI. At the effective time of the Merger, the
outstanding shares of capital stock of Murdock shall be converted into the right
to receive shares of the capital stock of the ABI (except as provided herein).
As a result, stockholders of Murdock shall become stockholders of ABI. The
transactions contemplated by this Agreement are subject to the approval of the
shareholders of Murdock, the Florida Department of Banking and Finance, the
Board of Governors of the Federal Reserve System, and the Federal Deposit
Insurance Corporation ("FDIC"), and the satisfaction of certain other conditions
described in this Agreement. It is the intention of the parties to this
Agreement that for federal income tax purposes the Merger shall qualify as a
"reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code, and for accounting purposes shall qualify for treatment as a "pooling of
interest".

         Certain capitalized terms used in this Agreement are defined in Section
11.1 of this Agreement.

         NOW, THEREFORE, in consideration of the above and the mutual
representations, warranties, covenants, and agreements herein contained, the
parties hereby agree as follows:

                                   ARTICLE I

                       THE MERGER AND RELATED TRANSACTIONS

         1.1 THE MERGER. Subject to the terms and conditions of this Agreement,
at the Effective Time, Murdock shall be merged with and into American Bank in
accordance with the provisions of the FFIC. At the Effective Time, the separate
corporate existence of Murdock shall cease, and American Bank, which shall
remain a wholly-owned subsidiary of ABI, shall be the surviving corporation
resulting from the Merger (the "Surviving Corporation") and shall continue to be
governed by the laws of the State of Florida. The Merger will be consummated
pursuant to the terms of this Agreement, which has been approved and adopted by
the respective Board of Directors of ABI, American Bank, and Murdock, and the
Plan of Merger in substantially the form set forth in Exhibit A and is
incorporated herein by reference, which has been approved and adopted by the
Board of Directors of American Bank and Murdock. From and after the Effective
Time, the Merger shall have the effects set forth in the FFIC.
<PAGE>   6
         1.2 TIME AND PLACE OF CLOSING. The closing of the transactions
contemplated hereby (the "Closing"), including the Merger, will take place at
the offices of Carlton, Fields, Ward, Emmanuel, Smith & Cutler, P.A., One
Harbour Place, 777 South Harbour Island Drive, Tampa, Florida 33601, at 10:00
a.m. local time on a date specified by the parties as they, acting through their
chief executive officers or Chairman of the Board of Directors, may mutually
agree. Subject to the terms and conditions hereof, unless mutually agreed upon
in writing by each party, the parties shall use their reasonable best efforts to
cause the Closing to occur on or before the fifth business day following the
Determination Date.

         1.3 EFFECTIVE TIME. The Merger and other transactions contemplated by
this Agreement shall become effective on the date and at the time on which the
articles of merger ("Articles of Merger") containing the provisions required by,
and executed in accordance with, the Florida Business Corporation Act ("FBCA"),
shall have been accepted for filing by the Secretary of State of the State of
Florida or such later date and time as is agreed upon in writing by ABI and
Murdock and specified in the Articles of Merger (the "Effective Time"). Unless
ABI and Murdock otherwise mutually agree in writing, the parties to this
Agreement shall use their best efforts to cause the Effective Time to occur on
the date of Closing.

                                   ARTICLE II

                                 TERMS OF MERGER

         2.1 ARTICLES OF INCORPORATION. Pursuant to the Merger, the articles of
incorporation of American Bank in effect immediately prior to the Effective Time
shall be the articles of incorporation of the Surviving Corporation until
otherwise amended and repealed in accordance with applicable law.

         2.2 BYLAWS. Pursuant to the Merger, the Bylaws of the American Bank in
effect immediately prior to the Effective Time shall be the bylaws of the
Surviving Corporation until otherwise amended or repealed in accordance with
applicable law.

         2.3 DIRECTORS AND OFFICERS. From and after the Effective Time, the
directors and officers of American Bank immediately prior to the Effective Time
shall be the directors and officers of the Surviving Corporation, each to hold
office in accordance with the articles of incorporation and bylaws of the
Surviving Corporation.

                                   ARTICLE III

                           MANNER OF CONVERTING SHARES

         3.1 CONVERSION. Subject to the provisions of this Article III, at the
Effective Time, by virtue of the Merger and without any action on the part of
the shareholders of ABI or Murdock, the shares of the constituent corporations
shall be converted as follows:

                  (a) Except for shares of Murdock Common Stock issued and
outstanding immediately prior to the Effective Time as to which dissenters'
rights have been perfected and not withdrawn, and subject to Section 3.4
relating to fractional shares, each share of Murdock Common Stock (excluding
shares to be cancelled pursuant to Section 3.3 of this Agreement) issued and


                                       -2-
<PAGE>   7
outstanding at the Effective Time shall cease to be outstanding and shall be
converted into and exchanged for 2.40 ABI Common Shares (the "Exchange Ratio").
The Exchange Ratio shall be fixed and no adjustment shall be made except
pursuant to Section 3.2 of this Agreement unless the Designated Price of the ABI
Common Shares is less than $11.00, the Closing Equity is less than $5,000,000,
or both, in which case the Exchange Ratio shall be adjusted in accordance with
Section 3.1(b) of this Agreement.

                  (b) If the Designated Price of ABI Common Shares is less than
$11.00 and the Closing Equity is at least $5,000,000, then the Exchange Ratio
shall be increased to equal the quotient, rounded to the third decimal point,
of: (x) the product of $11.00 and the Exchange Ratio divided by (y) the
Designated Price. If the Designated Price shall be less than $10.00, then ABI
and Murdock shall in good faith attempt to negotiate a mutually acceptable
Merger Consideration for the Murdock Common Stock; provided, however, that if a
mutually agreed upon Merger Consideration is not negotiated within four days
following the Determination Date, then Murdock may terminate this Agreement
pursuant to Section 10.1(i) of this Agreement. If the Closing Equity shall be
less than $5,000,000, then the Exchange Ratio shall be adjusted as follows: (i)
if the Designated Price is $11.00 or more, then the Exchange Ratio shall be
decreased to equal the quotient, rounded to the third decimal point, of (A) the
quotient of [Closing Equity multiplied by 2.25, divided by 385,015] divided by
(B) 12.169, or (ii) if the Designated Price is less than $11.00, then the
Exchange Ratio shall be adjusted to equal the quotient, rounded to the third
decimal point, of (A) the quotient of [Closing Equity multiplied by 2.25,
divided by 385,015] divided by (B) 11.00. If the Closing Equity shall be less
than $4,875,000, then ABI and Murdock shall in good faith attempt to negotiate a
mutually acceptable Merger Consideration for the Murdock Common Stock; provided,
however, that if a mutually agreed upon Merger Consideration is not negotiated
within four days following the determination of Closing Equity, then ABI may
terminate the Agreement pursuant to Section 10.1(j) of this Agreement.

                  (c) Each of the Surviving Corporation common shares, $1.175
par value per share, issued and outstanding immediately prior to the Effective
Time shall remain issued and outstanding from and after the Effective Time.

                  (d) Each of the ABI Common Shares issued and outstanding
immediately prior to the Effective Time shall remain issued and outstanding from
and after the Effective Time.

         3.2 ANTI-DILUTION PROVISIONS. In the event that ABI changes the number
of ABI Common Shares issued and outstanding prior to the Effective Time as a
result of a stock split, stock dividend, recapitalization, reclassification, or
other similar transaction with respect to such ABI Common Shares and the record
date therefor (in the case of a stock dividend) or the effective date thereof
(in the case of a stock split or similar recapitalization for which a record
date is not established) shall be prior to the Effective Time, the Merger
Consideration shall be proportionately adjusted so as to prevent any dilutive
effect to the stockholders of Murdock which would otherwise result from any such
transaction on a percentage of ownership basis.

         3.3 SHARES HELD BY MURDOCK. Each share of Murdock Common Stock held by
Murdock as treasury stock, other than those shares of Murdock Common Stock held
in a fiduciary capacity or as a result of debts previously contracted, shall be
cancelled and retired at the Effective Time and shall cease to exist and no
consideration shall be exchanged therefor. All ABI Common Shares that are owned
by Murdock shall become treasury stock of ABI.


                                       -3-
<PAGE>   8
         3.4 FRACTIONAL SHARES. Notwithstanding any other provision of this
Agreement, each holder of shares of Murdock Common Stock exchanged pursuant to
the Merger who would otherwise have been entitled to receive a fraction of an
ABI Common Share (after taking into account all certificates delivered by such
holder) shall receive, in lieu thereof, cash (without any interest thereon) in
an amount equal to such fractional part of an ABI Common Share multiplied by the
"market price" of one ABI Common Share at the Closing. The "market price" of one
ABI Common Share at the Closing shall be the closing price of such common shares
on Nasdaq (as reported by the Wall Street Journal or, if not reported thereby,
any other authoritative source selected by ABI) on the last trading day
preceding the Closing. No such holder will be entitled to dividends, voting
rights, or any other rights as a shareholder in respect of any fractional share.

         3.5 CONVERSION OF STOCK OPTIONS.

                  (a) At the Effective Time, each award, option, or other right
to purchase or acquire ABI Common Shares pursuant to any stock awards, stock
options, stock appreciation rights or other benefits ("Murdock Rights") granted
and under any employee stock option or compensation plan or arrangement of
Murdock ("Murdock Stock Plans") which are outstanding at the Effective Time,
whether or not vested or exercisable, without any action on the part of the
holder thereof, shall be converted into and become rights with respect to ABI
Common Shares, and ABI shall assume each Murdock Right, in accordance with the
terms of the Murdock Stock Plan and stock option agreement or award by which it
is evidenced, except that from and after the Effective Time (i) ABI and its
Compensation Committee shall be substituted for Murdock and the committee of
Murdock's Board of Directors (including, if applicable, the entire Board of
Directors of Murdock) administering such Murdock Stock Plan, (ii) each Murdock
Right assumed by ABI may be exercised solely for ABI Common Shares (or cash in
the case of stock appreciation rights), (iii) the number of ABI Common Shares
subject to such Murdock Right shall be equal to the number of ABI Common Shares
subject to such Murdock Right immediately prior to the Effective Time multiplied
by the Exchange Ratio, and (iv) the per share exercise price (or similar
threshold price, in the case of stock awards) under each such Murdock Right
shall be adjusted by dividing the per share exercise (or threshold) price under
each such Murdock Right by the Exchange Ratio and rounding up to the nearest
cent. Notwithstanding the provisions of clause (iii) of the proceeding sentence,
ABI shall not be obligated to issue any fraction of an ABI Common Share upon
exercise of Murdock Rights and any fraction of an ABI Common Share that
otherwise would be subject to a converted Murdock Right shall represent the
right to receive a cash payment equal to the product of such fraction and the
difference between the market price of one ABI Common Share and the per share
exercise price of such right. In addition, notwithstanding the provisions of
clauses (iii) and (iv) of the first sentence of this Section 3.5(a), each
Murdock Right which is an "incentive stock option" shall be adjusted as required
by Section 424 of the Internal Revenue Code, and the regulations promulgated
thereunder, so as not to constitute a modification, extension, or renewal of the
option, within the meaning of Section 424(h) of the Internal Revenue Code. ABI
agrees to take all necessary steps to effectuate the foregoing provisions of
this Section 3.5.

                  (b) As soon as practicable after the Effective Time, ABI shall
deliver to the participants in each Murdock Stock Plan an appropriate notice
setting forth such participant's rights pursuant thereto and the grants pursuant
to such Murdock Stock Plan shall continue in effect on the same terms and
conditions (subject to the adjustments required by Section 3.5(a) of this
Agreement after giving effect to the Merger), and ABI shall comply with the
terms of each Murdock Stock Plan to ensure, to the extent required by, and
subject to the provisions of, such Murdock Stock Plan, that


                                       -4-
<PAGE>   9
the Murdock Rights which qualified as incentive stock options prior to the
Effective Time continue to qualify as incentive stock options after the
Effective Time. At or prior to the Effective Time, ABI shall take all corporate
action necessary to reserve for issuance sufficient ABI Common Shares for
delivery upon exercise of Murdock Rights assumed by ABI in accordance with this
Section 3.5. None of the ABI Common Shares to be issued upon conversion or
exercise of converted Murdock Rights will be required to be registered under the
Securities Act or any blue sky or state securities Laws.

                  (c) All restrictions or limitations on transfer with respect
to Murdock Common Stock awarded under the Murdock Stock Plans, to the extent
that such restrictions or limitations shall not have already lapsed, and except
as otherwise expressly provided in such plan, program, or arrangement, shall
remain in full force and effect with respect to ABI Common Shares into which
such restricted stock is converted pursuant to Section 3.1 of this Agreement.

                  (d) Prior to the Effective Time, Murdock will make any
amendments to the terms of the Murdock Stock Plans that are necessary to give
effect to the transactions contemplated by this Section 3.5. Murdock represents
that neither the execution of this Agreement nor the consummation of the
transactions contemplated hereby will cause the acceleration of vesting, the
lapse of repurchase rights or obligations, or the triggering of any other
benefits, rights, or protections occurring upon a change of control of Murdock
with respect to any Murdock Rights under any Murdock Stock Plan or otherwise.
Except as contemplated by this Section 3.5(d), Murdock will not, after the date
hereof, without the written consent of ABI, amend any outstanding Murdock Rights
or other options or rights to purchase shares of Murdock Common Stock (including
accelerating the vesting or lapse of repurchase rights or obligations).

         3.6 DISSENTER'S SHARES. Notwithstanding Section 3.1(a) of this
Agreement, shares of Murdock Common Stock issued and outstanding at the
Effective Time which are held by a holder who has not voted in favor of the
Merger and who has demanded payment for such shares in accordance with Section
658.44 of the Florida Statutes ("Dissenting Murdock Shares") shall not be
converted into or represent the right to receive the ABI Common Shares payable
thereon pursuant to Section 3.1 of this Agreement, and shall be entitled only to
such rights of appraisal as are granted by Section 658.44 of the Florida
Statutes ("Dissent Provisions"), unless and until such holder fails to perfect
or effectively withdraws or otherwise loses his or her right to appraisal. If
after the Effective Time any such holder fails to perfect or effectively
withdraws or loses his right to appraisal, such shares of Murdock Common Stock
shall be treated as if they had been converted at the Effective Time into the
right to receive the ABI Common Shares payable thereon pursuant to Section 3.1
of this Agreement. Murdock shall give ABI prompt notice upon receipt by Murdock
of any written objection to the Merger and such written demands for payment for
shares of Murdock Common Stock under the Dissent Provisions, and the withdrawals
of such demands, and any other instruments provided to Murdock pursuant to the
Dissent Provisions (any shareholder duly making such demand being hereinafter
called a "Dissenting Shareholder"). Each Dissenting Shareholder that becomes
entitled, pursuant to the Dissent Provisions, to payment for any shares of
Murdock Common Stock held by such Dissenting Shareholder shall receive payment
therefor from ABI (but only after the amount thereof shall have been agreed upon
or at the times and in the amounts required by the Dissent Provisions) and all
of such Dissenting Shareholders shares of Murdock Common Stock shall be
cancelled. Murdock shall not, except with the prior written consent of ABI,
voluntarily make any payment with respect to, or settle or offer to settle, any
demand for payment by a Dissenting Shareholder.

<PAGE>   10
         3.7 TRANSFERS. At the Effective Time, the stock transfer books of
Murdock shall be closed as to holders of Murdock Common Stock immediately prior
to the Effective Time and no transfers of Murdock Common Stock by any such
holder shall thereafter be made or recognized. If, after the Effective Time,
certificates representing Murdock Common Stock are properly presented in
accordance with Section 4.1 of this Agreement to the exchange agent, which shall
be selected by ABI ("Exchange Agent"), such certificates shall be cancelled and
exchanged for certificates representing the number of whole ABI Common Shares
and a check representing the amount of cash for fractional shares, if any, into
which the Murdock Common Stock represented thereby were converted in the Merger
(the "Merger Consideration").

                                   ARTICLE IV

                               EXCHANGE OF SHARES

         4.1 EXCHANGE PROCEDURES. As of the Effective Time, ABI shall deposit or
shall cause to be deposited with the Exchange Agent for exchange in accordance
with this Article IV, certificates representing ABI Common Shares and cash in
such amounts necessary to provide all the Merger Consideration required to be
exchanged by ABI pursuant to the terms of this Agreement (such Merger
Consideration, together with any dividends or other distributions with respect
thereto, referred to herein as the "Exchange Fund"). As soon as reasonably
practicable after the Effective Time, ABI shall cause the Exchange Agent to mail
to each holder of record of shares of Murdock Common Stock immediately prior to
the Effective Time whose shares were converted pursuant to Section 3.1 of this
Agreement into the right to receive the Merger Consideration: (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the certificates theretofore representing shares of Murdock
Common Stock shall pass, only upon proper delivery of such certificates to the
Exchange Agent, and which shall be in such form and have such other provisions
as ABI may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Murdock Common Stock certificates in exchange for the Merger
Consideration. After the Effective Time, each holder of shares of Murdock Common
Stock issued and outstanding at the Effective Time (other than shares as to
which dissenters' rights have been perfected under the Dissent Provisions and
not withdrawn and other than shares to be cancelled pursuant to Section 3.3 of
this Agreement) shall surrender the certificate or certificates theretofore
representing such shares, together with such transmittal materials properly and
duly executed, to the Exchange Agent and promptly upon surrender shall receive
in exchange therefor the Merger Consideration, together with all declared but
unpaid dividends or distributions in respect of such shares (without any
interest thereon), and the Murdock Common Stock certificates so surrendered
shall forthwith be cancelled. The certificate or certificates for Murdock Common
Stock shall be duly endorsed as the Exchange Agent may require. ABI shall not be
obligated to deliver the consideration to which any former holder of Murdock
Common Stock is entitled as the result of the Merger until such holder
surrenders his certificate or certificates representing shares of Murdock Common
Stock for exchange as provided in this Section 4.1. If any certificate for ABI
Common Shares, or check representing cash in lieu of fractional shares and/or
declared by unpaid dividends or distributions, is to be issued in a name other
than that in which a certificate surrendered for exchange is issued, the
certificate so surrendered shall be properly endorsed and otherwise in proper
form for transfer and the person requesting such exchange shall affix any
requisite transfer tax stamps to the certificate surrendered or provide funds
for their purchase or establish to the reasonable satisfaction of the Exchange
Agent that no such taxes are payable.


                                       -6-
<PAGE>   11
         4.2 RIGHTS OF FORMER MURDOCK SHAREHOLDERS. Until surrendered for
exchange in accordance with the provisions of Section 4.1 of this Agreement,
each certificate theretofore representing shares of Murdock Common Stock (other
than those shares as to which dissenter's rights have been perfected under the
Dissent Provisions and not withdrawn, and other than shares to be cancelled
pursuant to Section 3.3 of this Agreement) shall from and after the Effective
Time represent for all purposes only the right to receive ABI Common Shares and
cash in lieu of fractional shares as set forth in this Agreement (without any
interest thereon). Whenever a dividend or other distribution is declared by ABI
on the ABI Common Shares, the record date for which is at or after the Effective
Time, the declaration shall include dividends or other distributions on all
shares issuable pursuant to this Agreement, but no dividend or other
distribution payable to the holders of record of ABI Common Shares at or
subsequent to the Effective Time shall be delivered to the holder of any
certificate representing shares of Murdock Common Stock issued and outstanding
at the Effective Time until such holder physically surrenders such certificate
for exchange as provided in Section 4.1 of this Agreement, promptly after which
time all such dividends or distributions shall be paid (without any interest
thereon).

         4.3 TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund
(including the proceeds of any investments thereof) which had been made
available to the Exchange Agent pursuant to Section 4.1 of this Agreement that
remain unclaimed by the former shareholders of Murdock for six (6) months after
the Effective Time shall be paid to ABI. Any former shareholders of Murdock who
have not theretofore complied with this Article IV shall thereafter look only to
ABI for payment of the Merger Consideration, and any unpaid dividends and
distributions on the ABI Common Shares deliverable in respect of each share of
Murdock Common Stock such shareholder holds as determined pursuant to this
Agreement, in each case, without any interest thereon. Any other provision of
this Agreement notwithstanding, neither ABI, American Bank, the Surviving
Corporation, nor shall the Exchange Agent be liable to a holder of Murdock
Common Stock for any amount paid or property delivered in good faith to a public
official pursuant to any abandoned property, escheat, or similar law.

                                    ARTICLE V

                    REPRESENTATIONS AND WARRANTIES OF MURDOCK

         Murdock hereby represents and warrants to ABI and American Bank as
follows:

         5.1 ORGANIZATION, STANDING, AND POWER. Murdock is a state banking
corporation duly organized, validly existing, and in active status under the
laws of the State of Florida, and has the requisite corporate power and
authority to own, lease, and operate its properties and to carry on its business
as it is now being conducted . Murdock is not required to be qualified or
licensed to do business as a foreign corporation in any other jurisdiction.
Murdock's deposits are insured by the FDIC to the maximum extent permitted by
Law. Murdock has provided to ABI true, complete, and correct copies of the
articles of incorporation and bylaws of Murdock, in each case as amended and in
effect on the date of this Agreement.

         5.2 AUTHORITY; NO CONFLICT.

                  (a) Murdock has all the requisite corporate power and
authority to execute and deliver this Agreement and, subject to the requisite
approval and adoption of this Agreement by the


                                       -7-
<PAGE>   12
stockholders of Murdock, to perform its obligations under this Agreement and
consummate the transactions contemplated hereby. The execution, delivery, and
performance of this Agreement by Murdock and the consummation by Murdock of the
transactions contemplated hereby, have been duly and validly authorized by all
necessary corporate action in respect thereof on the part of Murdock, subject in
the case of the consummation of the Merger contemplated hereby to the requisite
approval and adoption of this Agreement by the stockholders of Murdock as
contemplated by Section 8.3 of this Agreement. The affirmative vote of the
holders of a majority of the outstanding shares of Murdock Common Stock is the
only vote required of Murdock's capital stock necessary in connection with the
consummation of the Merger. No other vote of the holders of Murdock's capital
stock is necessary in conjunction with this Agreement or consummation of the
transactions contemplated hereby. This Agreement has been duly executed and
delivered by Murdock and, subject to such requisite stockholder approval of the
Agreement (and assuming due authorization, execution and delivery by ABI and
American Bank), the Agreement constitutes a legal, valid, and binding obligation
of Murdock enforceable against Murdock in accordance with its terms (except in
all cases to the extent as such enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, or similar Laws affecting
the enforcement of creditors' rights and remedies generally and except that the
availability of the equitable remedy of specific performance and injunctive
relief is subject to the discretion of the court before which any proceedings
may be brought).

                  (b) At a meeting duly called and held, the Board of Directors
of Murdock has determined that this Agreement and the transactions contemplated
hereby, including the Merger, are fair to and in the best interests of Murdock's
stockholders, approved and adopted this Agreement and the transactions
contemplated hereby, and resolved (subject to Section 8.3 of this Agreement) to
recommend approval and adoption of this Agreement by its stockholders. Murdock
has been advised that all of Murdock's directors and its President and Chief
Executive Officer intend to vote in favor of the approval and adoption of this
Agreement at the Stockholders' Meeting and have executed a letter agreement to
this effect with ABI in substantially the form as set forth in Exhibit B to this
Agreement.

                  (c) Except as disclosed in Section 5.2(c) of the Murdock
Disclosure Memorandum, neither the execution and delivery of this Agreement by
Murdock, nor the consummation by Murdock of the transactions contemplated
hereby, nor compliance by Murdock with any of the terms or provisions herein,
will (i) conflict with or violate any provision of the Articles of Incorporation
or Bylaws of Murdock, (ii) violate, conflict with, constitute or result in a

action, suit, proceeding, or investigation, whether civil, administrative, or
investigative, arising out of actions or omissions occurring at or prior to the
Effective Time (including the transactions contemplated by this Agreement) to
the full extent permitted under Florida Law and by Murdock's Articles of
incorporation and Bylaws as in effect as of the date hereof, including any
provisions relating to advances of expenses incurred in the defense of any
action, suit, or proceeding. If indemnification is sought hereunder, the
Indemnified Party shall notify ABI of the commencement of the litigation,
proceeding, or other action, or any overt threat with respect to any of the
foregoing; provided, however, that the failure to provide such notification
shall not relieve ABI from its indemnification obligations hereunder or
otherwise to such Indemnified Party unless and only to the extent that such
failure shall materially and adversely affect the ability of ABI to defend such
litigation, proceeding, or other action. Following such notification, ABI may
elect to assume the defense of such litigation, proceeding, or other action (and
the costs related thereto) and, upon such election, ABI shall not be liable for
any legal costs subsequently incurred by such Indemnified Party (other than the
costs of investigation or the production of documents or witnesses) unless (i)
ABI fails to provide legal counsel reasonably satisfactory to such Indemnified
Party in a timely manner, or (ii) such Indemnified Party shall have reasonably
concluded that (A) the representation of such Indemnified Party by legal counsel
selected by ABI would be inappropriate due to actual or potential conflicts of
interest or (B) there may be a legal defense available to such Indemnified Party
that are different from or additional to those available to the Company or any
other Indemnified Party represented by such legal counsel. Nothing set forth
herein shall preclude any Indemnified Party from retaining its own counsel at
its own expense. ABI agrees that it will not, without the prior written consent
of the Indemnified Parties, settle, compromise, or consent to the entry of
judgment in any pending or threatened claim, proceeding, or action in respect of
which indemnification could be sought hereunder (whether or not any Indemnified
Party is a party to such claim or proceeding) unless such settlement includes a
provision unconditionally releasing each Indemnified Party from and holding each
of them harmless against all liability in respect of claims by any releasing
party related to or arising out of such matters or any transaction or conduct in
connection therewith. Without limiting the generality of the foregoing, in any
case in which the approval of ABI is required to effectuate such
indemnification, ABI shall direct, or cause such ABI Company to 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 ABI and the
Indemnified Party. ABI shall, and shall cause the Surviving Corporation and all
other relevant ABI Companies to apply such rights of indemnification in good
faith and to the fullest extent permitted by applicable Law.

                  (b) Incident to any information furnished or disclosed by ABI
or any ABI Company in connection with the Registration Statement and the Proxy
Statement, and subject to applicable Law, ABI shall indemnify, defend, and hold
harmless Indemnified Parties against all costs, fees, or expenses (including
reasonable attorneys' fees) judgements, fines, penalties, losses, damages,
liabilities, and amounts paid in settlement in connection with any claim,
action, suit, proceeding, or investigation, whether civil, administrative, or
investigative, arising out of or under the Securities Laws or any state blue sky
or securities Laws based in whole or in part on (i) any untrue statement or
alleged untrue statement of a material fact contained in such documents
including any amendment or supplement to such document), (ii) any omission or
alleged omission to state in such documents a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
(iii) any violation of ABI or an ABI Company of the Securities Laws or any state
blue sky or securities Laws in connection with


                                      -33-
<PAGE>   38
such documents; provided, however, that neither ABI or any ABI Company will be
liable in any such case to the extent that any such claim, action, suit, or
investigation is based on any untrue statement or alleged untrue statement or
omission or alleged omission made in such Registration Statement or Proxy
Statement or any amendment or supplement thereto in reliance upon and in
conformity with information furnished in writing to ABI or any ABI Company by
Murdock or any Indemnified Party specifically for use therein.

                  (c) Murdock shall indemnify, and each Indemnified Party shall,
severally and not jointly, indemnify, defend, and hold harmless ABI, any ABI
Company, each of their directors, officers, employees, and agents, and each
person who controls ABI or any ABI Company against all costs, fees, or expenses
(including reasonable attorneys' fees) judgements, fines, penalties, losses,
damages, liabilities, and amounts paid in settlement in connection with any
claim, action, suit, proceeding, or investigation, whether civil,
administrative, or investigative, arising out of or under the Securities Laws or
any state blue sky or securities Laws based in whole or in part on (i) any
untrue statement or alleged untrue statement of a material fact contained in
such documents including any amendment or supplement to such document), (ii) any
omission or alleged omission to state in such documents a material fact required
to be stated therein or necessary to make the statements therein not misleading,
or (iii) any violation of Murdock or such Indemnified Party of the Securities
Laws or any state blue sky or securities Laws in connection with such documents;
provided, however, that each Indemnified Party will be liable only for, and
Murdock will be liable in any such case only to the extent that, any such claim,
action, suit, or investigation is based on any untrue statement or alleged
untrue statement or omission or alleged omission made in such Registration
Statement or Proxy Statement or any amendment or supplement thereto in reliance
upon and in conformity with information furnished in writing by Murdock or such
Indemnified Party, as the case may be, specifically for use therein.

                  (d) If ABI or the Surviving Corporation or any of its
successors or assigns shall consolidate with or merge into any other corporation
or entity and shall not be the continuing or surviving corporation or entity of
such consolidation or merger or shall transfer all or substantially all of its
assets to any person, corporation or entity, then in each case, proper provision
shall be made so that the successors and assigns of ABI shall assume the
obligations set forth in this Section 8.17

                  (e) The provisions of this Section 8.17 are intended to be for
the benefit of and shall be enforceable by, each Indemnified Party, his or her
heirs and representatives, and shall survive the consummation of the Merger and
be binding on all successors and assigns of ABI and the Surviving Corporation.

         8.18 SPOUSES SHARES. Murdock shall obtain and deliver to ABI prior to
the Stockholders' Meeting, letter agreements with respect to the Spouses Shares
in substantially the form set forth in Exhibit A hereto committing the holder of
such Spouses Shares in favor of the Merger at the Stockholders' Meeting and not
disposing of the Murdock Common Stock other than pursuant to the Merger.

                                   CONDITIONS

         9.1 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 hereby shall be subject to the satisfaction of the
following conditions, unless waived by both parties pursuant to Section 11.7 of
this Agreement:

                  (a) Stockholder Approval. The Stockholders of Murdock shall
have approved this Agreement, and the consummation of the transactions
contemplated hereby, including the Merger, as and to the extent required by Law.

                  (b) Regulatory Approval. Other than the filing of the Articles
of Merger contemplated by Section 1.3 hereof, all Consents of, filings and
registrations with, and notifications to, all Regulatory Authorities required
for consummation of the Merger shall have been obtained or made and shall be in
full force and effect and all waiting periods required by Law shall have
expired. No Consent obtained from any Regulatory Authority which is necessary to
consummate the transactions contemplated hereby shall be conditioned or
restricted in a manner (including requirements relating to the raising of
additional capital or the disposition of assets or properties) which in the
reasonably judgement of the Board of Directors of either party would so
materially adversely impact the economic or business benefits of the
transactions contemplated by this Agreement that, had such condition or
requirement been known, such party would not, in its reasonable judgment, have
entered into this Agreement.

                  (c) Legal Proceedings. No Governmental Entity of competent
jurisdiction shall have issued any injunction, order, decree, ruling, or other
legal restraint or prohibition, whether temporary, preliminary, or permanent (an
"Injunction") which is in effect and has the effect of preventing the
consummation of the Merger or any of the transactions contemplated thereby, nor
shall any such action or proceeding been commenced or be pending for the
purposes of obtaining an Injunction. No Law, judgment, order, Injunction, writ,
or decree shall have been enacted, entered, promulgated, or enforced by any
Governmental Entity which prohibits, restricts or makes illegal consummation of
the Merger.

                  (d) Registration Statement. The Registration Statement shall
have been declared effective under the Securities Act, and no stop orders
suspending the effectiveness of the Registration Statement shall have been
issued, and 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 and Consents under blue sky or state securities Laws or the
Securities Act or the Exchange Act relating to the issuance or trading of the
ABI Common Shares issuable pursuant to the Merger shall have been received.

                  (e) Pooling of Interests. Coopers & Lybrand L.L.P., ABI's
independent public accountants, shall have issued a letter, dated as of the
Effective Time, to ABI to the effect that the Merger will qualify for "pooling
of interests" accounting treatment under GAAP.

                  (f) Tax Opinion. Each party shall have received a written tax
opinion of Carlton, Fields, Ward, Emmanuel, Smith, & Cutler, P.A. in form and
substance reasonably satisfactory to such parties substantially to the effect
that (i) the Merger will constitute a reorganization within the meaning


                                      -35-
<PAGE>   40
of Section 368(a) of the Internal Revenue Code and that (ii) the exchange in the
Merger of the shares of Murdock Common Stock for ABI Common Shares will not give
rise to gain or loss to the shareholders of Murdock with respect to such
exchange (except to the extent of any cash received). In rendering such Tax
Opinion, Carlton, Fields, Ward, Emmanuel, Smith, & Cutler, P.A. may require and
shall be entitled to rely upon representations contained in certificates of
officers of Murdock and ABI and others in form and substance reasonably
satisfactory to such counsel.

         9.2 CONDITIONS TO OBLIGATIONS OF ABI TO EFFECT THE MERGER. The
obligations of ABI to perform this Agreement and to consummate the Merger and
the other transactions contemplated hereby are subject to the satisfaction of
the following additional conditions, unless waived by ABI pursuant to Section

                  (a) Representations and Warranties. The representations and
warranties of Murdock set forth in this Agreement shall be true and correct as

of the date of Closing, subject to such exceptions as do not have, and would not
be reasonably expected to have, individually or in the aggregate, a Material
Adverse Effect on Murdock or the Surviving Corporation following the Effective
Time. Notwithstanding any of the foregoing, the representations and warranties
of Murdock set forth in Section 5.3 of this Agreement shall be true and correct
in all respects (except for inaccuracies which are de minimis in amount).

contemplated hereby, or for preventing any default under any agreement,
contract, other instrument or Permit to which Murdock is a party, which, if not
obtained or made, is reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect after the Effective Time on the Surviving
Corporation.

                  (d) Certificates. Murdock shall have delivered to ABI (i) a

that ABI may reasonably request relating to the existence of Murdock and
certified copies of resolutions or written consents duly adopted by Murdock's
Board of Directors evidencing the taking of all corporate action necessary to
authorize the execution, delivery, and performance of this Agreement, and the
consummation of the transactions contemplated hereby, all in such reasonable
detail as ABI and its counsel may request.

                  (e) Affiliates Agreements. ABI shall have received from each
affiliate of Murdock, the affiliates letter referred to in Section 8.16 of this
Agreement, to the extent necessary to assure in the reasonable judgment of ABI
that the transactions contemplated hereby will qualify for pooling of interests
accounting treatment.

warranties of ABI set forth in this Agreement shall be true and correct as of
the date of this Agreement and (except to the extent such representations and
warranties are by their express provisions made as of a specified date shall
speak only as of such date) as of the date of Closing as though made on and as
of the date of Closing, subject to such exceptions as do not have, and would not
be reasonably expected to have, individually or in the aggregate, a Material
Adverse Effect on Murdock or the Surviving Corporation following the Effective
Time.

                                   TERMINATION

         10.1 TERMINATION. Notwithstanding any other provision of this
Agreement, this Agreement may be terminated and the Merger abandoned at any time
prior to the Effective Time by action taken or authorized by the Board of
Directors of the terminating party or parties, whether before or after approval
of the matters presented in connection with the Merger by the stockholders of
Murdock:

                  (a) by mutual written consent of ABI and Murdock; or

                  (b) by either ABI or Murdock: (i) in the event of an
inaccuracy of any representation or warranty of the other party contained in
this Agreement which cannot be or has not been cured within thirty (30) days
after the giving of written notice of such inaccuracy and which inaccuracy would
provide the terminating party with the ability to refuse to consummate the
Merger under applicable standard set forth in Section 9.2(a) of this Agreement
in the case of Murdock and 9.3(a) in the case of ABI (provided that the
terminating party is not then in material breach of any representation or
warranty contained in this Agreement under the applicable standard set forth in
Section 9.2(a) of this Agreement in the case of Murdock and Section 9.3(a) in
the case of ABI, or in material breach of any covenant or other agreement
contained in this Agreement), or (ii) in the event of a material breach by the
other party of any covenant, agreement, or obligation contained in this
Agreement which breach cannot be or has not been cured within thirty (30) days
after giving of written notice to the breaching party of such breach; or

                  (c) by either ABI or Murdock, in the event (i) any Consent of
any Regulatory Authority required for consummation of the Merger and the other
transactions contemplated hereby shall have been denied by a final nonappealable
action of such Regulatory Authority or if such action taken by such Regulatory
Authority is not appealed within the time limit for appeal, or (ii) the
stockholders of Murdock fail to vote their approval of this Agreement and the
transactions contemplated hereby as required by the FFIC at the Stockholders'
Meeting where the transactions were presented to the stockholders for approval
and voted upon; or


                                      -38-
<PAGE>   43
                  (d) by either ABI or Murdock, in the event that the Merger
shall not have been consummated by April 30, 1998; provided, however, that the
right to terminate this Agreement pursuant to this Section 10.1(d) shall not be
available to any party whose breach of its obligations under this Agreement has
been the cause of, or resulted in the failure of the Merger to be consummated on
or before such date; or

                  (e) by ABI in the event dissenters' rights are claimed,
pursuant to the Dissent Provisions, by persons owning in the aggregate more than
10% of the issued and outstanding shares of Murdock Common Stock; or

                  (f) by ABI or Murdock (provided that the terminating party is
not then in breach of any representation or warranty contained in this Agreement
under the applicable standard set forth in Section 9.2(a) of this Agreement in
the case of Murdock and Section 9.3(a) in the case of ABI or in material breach
of any covenant or other agreement contained in this Agreement) in the event
that any of the conditions precedent to the obligations of such party to
consummate the Merger cannot be satisfied or fulfilled by the date specified in
Section 10.1(d) of this Agreement; or

                  (g) by Murdock, if prior to the Effective Time a corporation,
partnership, person, or other entity or group shall have made a bona fide
Acquisition Proposal that the Board of Directors of Murdock determines in its
good faith and in the exercise of its fiduciary duties based on, with respect to
legal matters, the written opinion of counsel, and with respect to financial
matters, in the written opinion of an investment banking firm of national
reputation with respect to the business conducted by Murdock, ABI, and similar
banks and bank holding companies, that the Acquisition Proposal is more
favorable to the stockholders of Murdock and that the failure to terminate this
Agreement and accept such Acquisition Proposal would be inconsistent with the
proper exercise of such fiduciary duties (it being agreed for purposes of this
Agreement that the firm of Allen C. Ewing & Co. is an investment banking firm of
such national reputation); provided, however, that termination under this
Section 10.1(g) shall not have been deemed effective until the termination fee
required by Section 10.3 hereof has been paid to ABI; or

                  (h) by ABI, if the Board of Directors of Murdock (i) shall
withdraw, modify, or change its recommendation to its stockholders with respect
to approval of this Agreement or the Merger contemplated thereby or shall have
resolved to engage in any Acquisition Proposal, (ii) shall have recommended to
the stockholders of Murdock any Acquisition Proposal, or (iii) shall have made
any public announcement of a proposal, plan, or intention to do any of the
foregoing or shall have entered into and have any agreement, written or oral, to
enter into, any agreement, contract, understanding, or arrangement to engage in
any of the foregoing.

                  (i) by Murdock, if the Designated Price is less than $10.00
and its Board of Directors determines by a vote of a majority of the members of
its entire Board of Directors, at any time commencing on the fourth day
following the Determination Date and ending on the close of business on the day
before Closing, to terminate; provided, however, before exercising its rights to
effect termination under this Section 10.1(i), Murdock shall first have
satisfied the good faith procedures specified in Section 3.2(b)of this
Agreement, it being agreed that it shall not be a failure to negotiate in good
faith if the Murdock Board of Directors declines to agree to a new Merger
Consideration because it has determined in its reasonable business judgment that
there has been a Material Adverse Change in the financial condition, results of
operations, business or prospects of ABI.


                                      -39-
<PAGE>   44
                  (j) by ABI, if the Closing Equity shall be less than
$4,875,000; provided, however, that before exercising its rights to effect
termination under this Section 10.1(j), ABI shall have first satisfied the good
faith procedures specified in Section 3.2(b) of this Agreement, it being agreed
that it shall not be a failure to negotiate in good faith if the ABI Board of
Directors declines to agree to a new Merger Consideration because it has
determined in its reasonable business judgment that there has been a Material
Adverse Change in the financial condition, results of operations, business or
prospects of Murdock.

         10.2 EFFECT OF TERMINATION. In the event of the termination and
abandonment of this Agreement pursuant to Section 10.1 of this Agreement, this
Agreement shall become void and have no effect and no party shall have any
obligation to the other parties hereto with respect to this Agreement, except
that (i) the provisions of this Section 10.2 and Sections 10.3, 11.1, and 11.2
of this Agreement shall survive any termination and abandonment, and (ii) that a
termination pursuant to Sections 10.1(b) of this Agreement shall not relieve or
release the breaching party from liability for an uncured willful breach of a
representation, warranty, consent, or agreement giving rise to such termination,
of this Agreement.

         10.3 TERMINATION FEE. (a) In the event that this Agreement is
terminated or the transactions contemplated hereby are abandoned pursuant to
Section 10.1(b) of this Agreement due to the failure or breach of Murdock under
this Agreement, Murdock shall reimburse ABI for its reasonable out-of-pocket
expenses relating to the Merger (consisting of costs and expenses of outside
legal counsel, printing expenses, fiscal expense reimbursements for its
financial advisor and accountants) in an amount not to exceed $250,000.

                  (b) In the event this Agreement is terminated or the
transactions contemplated hereby are abandoned pursuant to Sections 10.1(g) or
10.1(h) of this Agreement, ABI shall be entitled to a cash payment from Murdock
in an amount equal to $750,000. In the event of a termination of this Agreement
pursuant to Section 10.1(g) or 10.1(h) of this Agreement, the payments provided
under this Section 10.3(b) shall be the sole and exclusive remedy available to
ABI.

                  (c) In the event this Agreement is terminated as a result of
ABI's failure or breach under Section 10.1(b), ABI shall reimburse Murdock for
its reasonable out-of-pocket expenses relating to the Merger (consisting of
costs and expenses of outside legal counsel, printing expenses, fees and expense
reimbursement for its financial advisor and accountants) in an amount not to
exceed $200,000.

                                 FIRST AMENDMENT
                                       TO
                          AGREEMENT AND PLAN OF MERGER


         FIRST AMENDMENT TO AGREEMENT AND PLAN OF MERGER (this "First

("ABI"), a Florida corporation having its principal office located in Bradenton,

having its principal office located in Murdock, Florida.

                                    PREAMBLE

         The parties hereto entered into an Agreement and Plan of Merger, dated
as of September 23, 1997 ("Merger Agreement"), whereby ABI, American Bank, and
Murdock agreed to the merger of Murdock with and into American Bank. The parties
now desire to amend the Merger Agreement on the terms and conditions set forth
herein for the purpose of making certain corrective revisions.

         NOW, THEREFORE, in consideration of the above and the mutual
representations, warranties, covenants, and agreements herein contained, the
parties hereby agree as follows:

         1. AMENDMENTS TO THE MERGER AGREEMENT.

                  (A) CONVERSION OF MURDOCK COMMON STOCK - ADJUSTMENT OF
         EXCHANGE RATIO. Section 3.1(b) of the Merger Agreement is hereby
         amended by deleting Section 3.1(b) in its entirety and by insertion, in
         lieu thereof, of the following:

                           (b) If the Designated Price of ABI Common Shares is
                  less than $11.00 and the Closing Equity is at least
                  $5,000,000, then the Exchange Ratio shall be increased to
                  2.65. If the Designated Price shall be less than $10.00, then
                  ABI and Murdock shall in good faith attempt to negotiate a
                  mutually acceptable Merger Consideration for the Murdock
                  Common Stock; provided, however, that if a mutually agreed
                  upon Merger Consideration is not negotiated within four days
                  following the Determination Date, then Murdock may terminate
                  this Agreement pursuant to Section 10.1(i) of this Agreement.
                  If the Closing Equity shall be less than $5,000,000, then the
                  Exchange Ratio shall be adjusted as follows: (i) if the
                  Designated Price is $11.00 or more, then the Exchange Ratio
                  shall be decreased to equal the quotient, rounded to the third
                  decimal point, of (A) the quotient of [Closing Equity
                  multiplied by 2.25, divided by 385,015] divided by (B) 12.169,
                  or (ii) if the Designated Price is less than $11.00, then the
                  Exchange Ratio shall be adjusted to equal the quotient,
                  rounded to the third decimal point, of (A) the quotient of
                  [Closing Equity multiplied by 2.25, divided by 385,015]
                  divided by (B) 11.00. If the Closing Equity shall be less than
                  $4,875,000, then ABI and Murdock shall in good faith attempt
                  to negotiate a mutually acceptable Merger Consideration for
                  the Murdock Common Stock; provided, however, that if a
                  mutually agreed upon Merger Consideration is not negotiated
                  within four days following the determination of Closing
                  Equity, then ABI may terminate the Agreement pursuant to
                  Section 10.1(j) of this Agreement.

         Stock set forth in Section 11.1(a) of the Merger Agreement is hereby
         amended by deleting the definition of Murdock Common Stock set forth in

                         AMERICAN BANCSHARES TO ACQUIRE
                              MURDOCK FLORIDA BANK

         BRADENTON, Fla., Sept. 24 -- American Bancshares, Inc., the bank
holding company for American Bank of Bradenton, and Murdock Florida Bank
announced today that they have signed a definitive merger agreement under which
American Bancshares will acquire Murdock on a stock-for-stock basis valued at
$29.22 per share in a tax-free exchange. The merger has an aggregate
transaction value of $11,250,000.

         The purchase price is approximately 2.25 times Murdock's book value
and 18.8 times Murdock's June 30, 1997 earnings. The acquisition is expected to
close in the fourth quarter of 1997 and to be accounted for as a pooling of
interests. Based upon information provided by Murdock Florida Bank, American
Bancshares management believes that the transaction will be accretive to 1998
earnings in excess of 10 percent.

         The exchange ratio of 2.40 shares of American Bancshares stock for
each share of Murdock Florida Bank stock was fixed at the signing of the
definitive merger agreement. The exchange ratio will be adjusted if the 20-day
average of the daily closing price of American Bancshares' common stock is
below $11.00 per share at closing so that the aggregate transaction value
equals $11,250,000. In addition, Murdock Florida Bank can terminate the
transaction if the 20 day average falls below $10.00 per share at closing.

         American Bancshares is a one-bank holding company headquartered in
Bradenton, Florida. Its wholly-owned subsidiary, American Bank of Bradenton,
with six branch offices is the leading and largest independent community bank
in Manatee County. Murdock Florida Bank is a community bank serving Murdock,
Florida and the surrounding area of northern Charlotte County and southern
Sarasota County.

         American Bancshares President and CEO Gerald L. Anthony said, "This
acquisition complements our position as one of the leading independent
community banks in our market area." Mr. Anthony said, "Murdock is located in
one of the fastest growing areas in the state of Florida. We are pleased with
this opportunity to strengthen our customer base, and Murdock's operations are
a good match with ours. We feel this transaction benefits the shareholders and
customers of both institutions."

long-term interests of shareholders, customers and employees are served by our
merger with American Bancshares. Our institutions share common business
philosophies and a strong commitment to the communities we serve. The merger
increases our capacity to provide financial services to our growing number of
customers."

both American Bancshares and Murdock. The merger must also be approved by
Murdock shareholders and by federal and state bank regulatory authorities and
