                 MULTI-YEAR NON-QUALIFIED STOCK OPTION AGREEMENT


THIS AGREEMENT made and entered into this 5th day of August, 1999, by and
between FIRSTMERIT CORPORATION, (the "Company"), and John R. Macso, (the
"Optionee").

WITNESSETH, THAT:

WHEREAS, the Company on the 9th day of April, 1997, by action of its
shareholders, adopted and approved the 1997 Stock Option Program ("Plan"); and

WHEREAS, the purpose of said Plan is to enable selected and key employees of the
Company and its subsidiaries to acquire a proprietary interest in the Company
through such Plan, and to provide such employees with a more direct stake in the
future and welfare of the Company and its subsidiaries and to encourage them to
remain with the Company or its subsidiaries.

NOW THEREFORE, the Company and Optionee agree as follows:

         1.       Amount of Stock Subject to Option.

                  a.       The Company hereby grants to Optionee the right to
                           purchase 48,000 shares of authorized and unissued
                           common stock of the Company, which stock is to be
                           issued by the Company upon the exercise of this
                           option as hereinafter set forth.

                  b.       The Company also hereby grants to Optionee one
                           Dividend Unit with respect to each share of stock for
                           which this option has been granted.

         2.       Purchase Price.

                  The purchase price per share shall be twenty-six dollars
                  ($26.00) (not less than 100% of the fair market value of the
                  stock at the time the option is granted).

         3.       Period of Option.

                  a.       Shares granted as part of this option may not be
                           purchased until such time as they become exercisable.
                           Once such shares become exercisable, all or any part
                           of such shares may be purchased at any time within
                           ten (10) years of the date hereof, except as
                           otherwise provided in Section 8 of this Agreement.

   2

                  b.       One-third of this option, 16,000 shares, shall become
                           exercisable on February 18, 2000 and one-third of
                           this option, 16,000 shares, shall become exercisable
                           on February 18, 2001. If the net operating income
                           ("NOI") of Mobile Consultants, Inc. ("MCI"), a
                           wholly-owned subsidiary of the Company, equals or
                           exceeds the targeted NOI established for MCI by the
                           Company for both calendar year 2000 and calendar year
                           2001, then the final one-third of this option, 16,000
                           shares, shall become exercisable on February 18,
                           2002. If the NOI of MCI equals or exceeds the
                           targeted NOI established for MCI by the Company for
                           either calendar year 2000 or calendar year 2001, but
                           not both such calendar years, then this option shall
                           become exercisable on February 18, 2002 with respect
                           to only 5,000 of the final 16,000 shares that are
                           subject to this option and the Optionee's option to
                           purchase the remaining 11,000 shares shall be
                           forfeited and become null and void as of February 18,
                           2002. If the NOI of MCI is less than the targeted NOI
                           established for MCI by the Company for both calendar
                           year 2000 and calendar year 2001, then the Optionee's
                           option to purchase the final 16,000 shares that are
                           subject to this option shall be forfeited and become
                           null and void as of February 18, 2002.
                           Notwithstanding the foregoing, if the Chairman and
                           CEO of the Company determines, in his sole
                           discretion, that the failure of MCI to equal or
                           exceed its targeted NOI in calendar year 2000 or
                           calendar year 2001 is due to extraordinary
                           circumstances, then the Chairman and CEO of the
                           Company may, in his sole discretion, grant to the
                           Optionee the right to exercise this option with
                           respect to any of all of the final 16,000 shares that
                           are subject to this option. NOI shall be determined
                           in accordance with generally accepted accounting
                           principles applied consistently with the Company's
                           past practices.

                  c.       The terms of the Dividend Units granted herein shall
                           be ten (10) years from the date of grant hereof,
                           provided that the Dividend Units will accrue
                           dividends only for the first five (5) years of that
                           period.

         4.       General Terms and Conditions.

                  This option is subject to the terms and conditions of the
                  Plan, a copy of which is attached hereto and incorporated by
                  reference herein.

         5.       Exercise of Option.

                  In order to exercise this option or any part thereof, Optionee
                  shall give notice in writing to the Company of his or her
                  intention to purchase all or part of the shares subject to
                  this option, and in said notice shall be set forth the number
                  of shares as to which he or she desires to exercise this
                  option. Optionee shall pay for said shares in full at the time
                  of exercise in cash, by check, bank draft or money order
                  payable to the Company, or through the delivery of shares of
                  stock of the Company having an


                                       2
   3


                  aggregate fair market value as determined on the date of
                  exercise equal to the option price. No shares shall be issued
                  until final payment for said shares has been made, and
                  Optionee shall have none of the rights of a shareholder until
                  said shares are issued. Said notice to exercise this option
                  shall set forth that it is Optionee's present intention to
                  acquire said shares for investment, and not with a view to, or
                  for sale in connection with any distribution thereof, if in
                  the opinion of counsel for the Company it is necessary or
                  desirable.

         6.       Payment and Valuation of Dividend Units.


                  a.       The amount payable to Optionee in respect of each
                           Dividend Unit awarded herein shall be equal to the
                           aggregate dividends actually paid on one share of the
                           common stock of the Company, to the extent Optionee
                           held such Dividend Unit on the record date
                           established for payment of such dividends.

                  b.       Except as otherwise provided herein, the amount
                           payable to Optionee in respect of a Dividend Unit
                           shall be paid to Optionee only at the exercise of
                           this option with respect to the share of stock to
                           which the Dividend Unit is attached.

                  c.       A Dividend Unit shall have no further force or effect
                           upon payment in respect thereof.

         7.       Transferability of Option.

                  This option is transferable in accordance with the terms of
                  the Plan.

         8.       Termination of Employment and Death of Optionee.

                  a.       If Optionee shall cease to be employed by the Company
                           or one of its subsidiaries for any reason other than
                           death, disability (as defined in the Plan), or
                           retirement (as defined in the Plan), all rights to
                           purchase shares pursuant to this option which have
                           not been exercised shall be immediately canceled,
                           except that if the termination is by the Company or
                           any of its subsidiaries for any reason other than
                           misconduct or misfeasance, Optionee shall have thirty
                           (30) days thereafter within which to exercise this
                           option to the extent that this option was otherwise
                           exercisable immediately prior to such termination,
                           and further if such termination is attributable to a
                           change of control of the Company (as defined in the
                           Plan), the option shall not be canceled but shall
                           continue as though Optionee remained in the employ of
                           the Company or any of its subsidiaries during the
                           remaining term of the option.

                                       3
   4

                  b.       In the event of termination of employment due to
                           death, or disability (as defined in the Plan) of
                           Optionee, this option shall become immediately
                           exercisable and be exercisable for a period equal to
                           the lesser of five (5) years or the remaining option
                           term.

                  c.       In the event of termination due to Retirement (as
                           defined in the Plan) of Optionee, this option shall
                           become exercisable as specified in Section 3 of this
                           Agreement and be exercisable for a period equal to
                           the lesser of five (5) years or the remaining option
                           term.

                  d.       In the event of termination of employment, each
                           Dividend Unit granted herein shall remain outstanding
                           for the duration of this option until paid upon
                           exercise, but shall terminate upon termination,
                           cancellation or expiration of this option.

         9.       Changes in Capital.

                  If, prior to the expiration of this option, there shall be any
                  changes in the capitalization of the Company by reason of
                  stock dividends, stock splits, recapitalizations,
                  combinations, exchanges of shares, spin-off's, liquidations,
                  reclassifications or other similar events, then the number of
                  shares available for purchase hereunder and the option price
                  shall be adjusted proportionally by the Board of Directors of
                  the Company as in its sole discretion shall deem equitable.

         10.      The Right to Terminate Employment.

                  This option shall not confer upon Optionee any right to
                  continue in the employ of Company or its subsidiaries or to
                  interfere with or restrict in any way with the rights of the
                  Company or its subsidiaries to discharge Optionee at any time,
                  for any reason, with or without cause.

         11.      Listing, Registration, Qualification.

                  This option is subject to the requirement and condition that
                  if the Board of Directors shall determine that the listing,
                  registration or qualification upon any securities exchange
                  under any state or federal law, or the approval or consent of
                  any governmental body is necessary or desirable as a condition
                  to the issuance or purchase of any shares subject to this
                  option, then this option may not be exercised in whole or in
                  part unless or until such listing, registration, qualification
                  or approval has been obtained, free of any conditions which
                  are not acceptable to the Board of Directors of the Company,
                  and the sale and delivery of stock hereunder is also subject
                  to the above requirements and conditions.

                                       4
   5

         12.      Withholding.

                  The Company may require a payment from Optionee under the
                  exercise of this option to cover applicable withholding for
                  income and employment taxes. The Company reserves the right to
                  offset such tax payment from any funds which may be due
                  Optionee by the Company.

         13.      Reload Stock Option.

                  If this option is exercised while the Optionee is employed by
                  the Company or one of its subsidiaries and the Optionee pays
                  for the shares subject to option through the delivery of
                  shares of stock of the Company having an aggregate fair market
                  value as determined on the date of exercise equal to the
                  option price, Optionee is hereby granted a non-qualified stock
                  option on the date of such exercise (Reload Stock Option). The
                  grant equals the number of whole shares of stock of the
                  Company used to pay the purchase price, and the exercise price
                  of the Reload Stock Option is equal to the fair market value
                  of the stock of the Company on the date of grant. If the
                  Company withholds shares of stock of the Company to cover
                  applicable income and employment taxes related to the exercise
                  of this option, then the grant equals the number of whole
                  shares of stock of the Company used to pay the purchase price
                  less the number of shares withheld.

                  Subject to the provisions of the Plan, the Reload Stock Option
                  may be exercised between its date of grant and the date of
                  expiration of this option. This Reload Stock Option shall be
                  evidenced by an Agreement containing such other terms and
                  conditions as the Committee approves. No Reload Stock Option
                  shall be granted if this option is exercised after the
                  Optionee's retirement, permanent disability, death, or other
                  termination of employment.

                  If the option was exercised before accruing Dividend Units for
                  the number of years specified by the Committee at the time of
                  grant of the option, the Reload Stock Option is hereby granted
                  with Dividend Units that will accrue for the number of years
                  specified by the Committee at the time of grant of the option,
                  less the number of years Dividend Units actually accrued on
                  the option.
