         All documents filed by the Company with the Commission pursuant to
Sections 13(a), 3(c), 14, and 15(d) of the Securities Act of 1934, as amended
(the "Exchange Act") subsequent to the date of this Registration Statement, but
prior to the filing of a post-effective amendment to this Registration Statement
which indicates that all securities offered hereby have been sold or which
registers all such securities then remaining unsold, shall be deemed to be
incorporated in

                                       2

this registration Statement by reference and to be a part hereof from the date
of filing such documents.

         Any statement contained in this Registration Statement, in a supplement
to this Registration Statement or in documents incorporated by reference herein,
shall be deemed to be modified or superseded for purposes of this Registration
Statement to the extent that a statement contained herein or in any document
that is subsequently incorporated by reference herein modifies such statement.
Any statement so modified or superseded shall not be deemed, except as to
modified or superseded, to constitute a part of this Registration Statement.


ITEM 4. DESCRIPTION OF SECURITIES.

         Not applicable. The class of securities to be offered under this
Registration Statement is registered under Section 12 of the Exchange Act.


ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Shumaker, Loop & Kendrick, LLP, as legal counsel to the Company, is
giving an opinion as to the validity of the securities offered under this
Registration Statement. Edwin G. Emerson, Esq., a partner of Shumaker, Loop &
Kendrick, LLP, serves as a director of the Company and is the beneficial owner
of 2,370 shares of Common Stock of the Company as of March 1, 1999. Mr.
Emerson's spouse, Barbara K. Emerson, is a general partner of Myers Properties
Limited Partnership, which owns 61,716 shares of Common Stock of the Company.
Mr. Emerson disclaims beneficial ownership of the shares held by the
partnership. 


ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Company's Code of Regulations (the "Regulations") provides for the
indemnification of Directors and Officers by the Company against any cost or
expense, reasonably incurred by him or her in connection with any threatened,
pending, or completed action, suit or proceeding by reason of such or any
service to the Company or for service at the request of the Company as a
Director, Trustee, Officer, Employee or Agent of any other corporation,
partnership, joint venture, trust or other enterprise. This indemnification
includes the advancement of expenses including attorneys' fees incurred in
defending any such action, suit or proceeding to the full extent permitted by
Ohio General Corporation Law. The Company and its Directors and Officers shall
be fully protected in taking any action or making any payment under this
section, or in refusing to do so, in reliance upon the advice of counsel. The
Board of Directors is empowered to authorize the Company to purchase and
maintain insurance against liability on behalf of any Director, Officer,
Employee or Agent of the company to the full extent permitted by law.

         Insofar as indemnification for liabilities under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than payment by the registrant of expenses incurred or
paid by a director, officer, or 

                                       3

<PAGE>   4

controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

                           are being made, a post effective amendment to this
                           registration statement:

                           (i)      To include any prospectus required by

                                    which, individually or in the aggregate,
                                    represents a fundamental change in the

                                    statement.

<PAGE>   5


                           (iii)    To include any material information with

                                    statement or any material change to such
                                    information in the registration statement.

                  (b)      That, for the purpose of determining any liability
                           under the Securities Act of 1933, each such
                           post-effective amendment shall be deemed to be a new
                           registration statement relating to the securities
                           offered therein, and the offering of such securities
                           at that time shall be deemed to be the initial bona
                           fide offering thereof.

                   (c)     To remove from registration by means of a
                           post-effective amendment any of the securities being
                           registered which remain unsold at the termination of

          2. The undersigned Company hereby undertakes to deliver or cause to be
delivered with the Prospectus to each eligible employee or director to whom the
Prospectus is sent or given, a copy of the Company's Annual Report to
Stockholders for its last fiscal year, unless such individual otherwise has
received a copy of such Annual Report, in which case the Company shall state in
the Prospectus that it will promptly furnish, without charge, a copy of such
Annual Report on written notice of the individual. If the last fiscal year of
the Company has ended within 120 days prior to the use of the Prospectus, the
Annual Report of the Company for the preceding fiscal year may be so delivered,
but within such 120 day period the Annual Report for the last fiscal year will
be furnished to each such individual.

         The Company also undertakes to deliver or cause to be delivered to all
employees or directors participating in the Company's Deferred Compensation Plan
who do not otherwise receive such material, copies of all reports to
stockholders, proxy statements and other communications distributed to its
security holders generally, such material to be sent or delivered no later than
the time it is sent to security holders.

                         ELECTIVE AND MATCHING DEFERRALS

4.1      Elective Deferrals

         An individual who is an Eligible Employee on the Effective Date may, by
completing an Election Form and filing it with the Plan Administrator within 30
days following the Effective Date, elect to defer a percentage or dollar amount
of one or more payments of Compensation, on such terms as the Plan Administrator
may permit, which are payable to the Participant after the date on which the
individual files the Election Form. Any individual who becomes an Eligible
Employee after the Elective Date may, by completing an Election Form and filing
it with the Plan Administrator within 30 days following the date on which the
Plan Administrator gives such individual written notice that the individual is
an Eligible Employee, elect to defer a percentage or dollar amount of one or
more payments of Compensation, on such terms as the Plan Administrator may
permit, which are payable to the Participant after the date on which the
individual files the Election Form. Any Eligible Employee who has not otherwise
initially elected to defer Compensation in accordance with this paragraph 4.1
may elect to defer a percentage or dollar amount of one or more payments of
Compensation, on such terms as the Plan Administrator may permit, commencing
with Compensation paid in the next succeeding Plan Year, by completing an
Election Form prior to the first day of such succeeding Plan Year. In addition,
a Participant may defer all or part of the amount of any elective deferral or
matching contribution made on his or her behalf to the Employer's 401(k) plan
for the prior Plan Year but treated as an excess deferral, an excess
contribution or otherwise limited by the application of the limitations of
sections 401(k), 401(m), 415 or 402(g) of the Code, so long as the Participant
so indicates on an Election Form. A Participant's Compensation shall be reduced
in accordance with the Participant's election hereunder and amounts deferred
hereunder shall be paid by the Employer to the Trust as soon as administratively
feasible and credited to the Participant's Account as of the date the amounts
are received by the Trustee.

         An election to defer a percentage or dollar amount of Compensation for
any Plan Year shall apply for subsequent Plan Years unless changed or revoked. A
Participant may change or revoke his or her deferral election as of the first
day of any Plan Year by giving written notice to the Plan Administrator before
such first day (or any such earlier date as the Plan Administrator may
prescribe).

4.2      Matching Deferrals

         After each payroll period, monthly, quarterly, or annually, at the
Employer's discretion, the Employer shall contribute to the Trust Matching
Deferrals equal to the rate of Matching Contribution selected by the Employer
and multiplied by the amount of the Elective Deferrals credited to the
Participants' Accounts for such period under Section 4.1. Each Matching Deferral
will be credited, as of the later of the date it is received by the Trustee or
the date the Trustee receives from the Plan Administrator such instructions as
the Trustee may reasonably require to allocate the amount received among the
asset accounts maintained by the Trustee, to 

                                       4



<PAGE>   6

the Participants' Accounts pro rata in accordance with the amount of Elective
Deferrals of each Participant, which are taken into account in calculating the
Matching Deferral.

4.3      Incentive Contributions

         In addition to other contributions provided for under the Plan, the
Employer may, in its sole discretion, select one or more Eligible Employees to
receive an Incentive Contribution to his or her Account on such terms as the
Employer shall specify at the time it makes the contribution. For example, the
Employer may contribute an amount to a Participant's Account and condition the
payment of that amount and accrued earnings thereon upon the Participant
remaining employed by the Employer for an additional specified period of time.
The terms specified by the Employer shall supersede any other provision of this
Plan as regards Incentive Contributions and earnings with respect thereto,
provided that if the Employer does not specify a method of distribution, the
Incentive Contribution shall be distributed in a manner consistent with the
election last made by the particular Participant prior to the year in which the
Incentive Contribution is made. The Employer, in its discretion, may permit the
Participant to designate a distribution schedule for a particular Incentive
Contribution provided that such designation is made prior to the time that the
Employer finally determines that the Participant will receive the Incentive
Contribution.

                                    ACCOUNTS

         The Plan Administrator shall establish an Account for each Participant
reflecting Elective Deferrals, Matching Deferrals and Incentive Contributions
made for the Participant's benefit together with any adjustments for income,
gain or loss and any payments for the Account. The Plan Administrator may cause
the Trustee to maintain and invest separate asset accounts corresponding to each
Participant's Account. the Plan Administrator shall establish sub-accounts for
each Participant that has more than one election in effect under Section 7.1 and
such other subaccounts as are necessary for the proper administration of the
Plan. As of the last business day of each calendar quarter, the Plan
Administrator shall provide the Participant with a statement of his or her
Account reflecting the income, gains and losses (realized and unrealized),
amounts of deferrals, and distributions of such Account since the prior
statement.

5.2      Investments

         The assets of the Trust shall be invested in such investments as the
Trustee shall determine. The Trustee may (but is not required to) consider the
Employer's or a Participant's investment preferences when investing the assets
attributable to a Participant's Account.

                                     VESTING

6.1      General

         A Participant shall be immediately vested in, i.e., shall have a
nonforfeitable right to, all Elective Deferrals, and all income and gain
attributable thereto, credited to his or her Account. A Participant shall become
vested in the portion of his or her Account attributable to Matching Deferrals
and income and gain attributable thereto in accordance with the schedule
selected by the Employer in the Adoption Agreement, subject to earlier vesting
in accordance with Sections 6.3, 6.4 and 6.5.

6.2      Vesting Service

         For purposes of applying the vesting schedule in the Adoption
Agreement, a Participant shall be considered to have completed a Year of Service
for each complete year of full-time service with the Employer or an Affiliate,
measured from the Participant's first date of such employment, unless the
Employer also maintains a 401(k) plan that is qualified under section 401(a) of
the Internal Revenue Code in which the Participant participates, in which case
the rules governing vesting service under that plan shall also be controlling
under this plan.

6.3      Change of Control

         A Participant shall become fully vested in his or her Account
immediately prior to a Change of Control of Employer.

6.4      Death or Disability

         A Participant shall become fully vested in his or her Account
immediately prior to termination of the Participant's employment by reason of
the Participant's death or Total and Permanent Disability. Whether a
Participant's termination of employment is by reason of the Participant's Total
and Permanent Disability shall be determined by the Plan Administrator in its
sole discretion.

6.5      Insolvency

         A Participant shall become fully vested in his or her Account
immediately prior to the Employer becoming insolvent, in which case the
Participant will have the same rights as a general creditor of the Employer with
respect to his or her Account balance.

                                    PAYMENTS

7.1      Election as to Time and Form of Payment

         A Participant shall elect (on the Election Form used to elect to defer
Compensation under Section 4.1) the date at which the Elective Deferrals and
vested Matching Deferrals (including any earnings attributable thereto) will
commence to be paid to the Participant. The Participant shall also elect thereon
for payments to be paid in either:

         a. a single lump-sum payment;

         b. a series of substantially equal periodic payments (not less
         frequently than annually) over a period elected by the participant not
         to exceed the life expectancy of the participant (or the joint life
         expectancies of the Participant and the designated beneficiary of the
         Participant);

         c. payments equal to the amounts paid under an annuity chosen by the
         Participant that is acceptable to the Trustee;

         d. annual installments over a period elected by the Participant, the
         amount of each installment to equal the balance of his or her Account
         immediately prior to the installment divided by the number of
         installments remaining to be paid.

         Each such election will be effective for the Plan Year for which it is
made and succeeding Plan Years, unless changed by the Participant. Any change
will be effective only for Elective Deferrals and Matching Deferrals made for
the first Plan Year beginning after the date on which the Election Form
containing the change is filed with the Plan Administrator. Except as provided
in Sections 7.2, 7.3, 7.4, or 7.5, payment of a Participant's Account shall be
made in accordance with the Participant's elections under this Section 7.1.

7.2      Change of Control

         As soon as possible following a Change of Control of the Employer, each
Participant shall be paid his or her entire Account balance (including any
amount vested pursuant to Section 6.3) in a single lump sum.

7.3      Termination of Employment

         Upon termination of a Participant's employment for any reason other
than death and prior to the attainment of the Retirement Age specified in the
Adoption Agreement, the vested portion of the Participant's Account (including
any portion vested pursuant to Section 6.4 as a consequence of the Participant's
Total and Permanent Disability) shall be paid to the Participant in a single
lump sum as soon as practicable following the date of such termination;
provided,

                                       7
<PAGE>   9

 however, that the Plan Administrator, in its sole discretion, may pay
out a Participant's Account balance in annual installments if the Participant's
employment terminates by reason of the Participant's Total and Permanent
Disability.

7.4      Death

         If a Participant dies prior to the complete distribution of his or her
Account, the balance of the Account shall be paid as soon as practicable to the
Participant's designated beneficiary or beneficiaries, in accordance with the
payment election in effect under Section 7.1 on the date of the Participant's
death. Alternatively, Participant may elect that the balance of the Account be
paid to the Participant's beneficiary or beneficiaries.

         Any designation of beneficiary and form of payment to such beneficiary
shall be made by the Participant on an Election Form filed with the Plan
Administrator and may be changed by the Participant at any time by filing
another Election Form containing the revised instructions. If no beneficiary
survives the Participant, payment shall be made to the Participant's surviving
spouse, or, if none, to his or her issue per stirpes, in a single payment. If no
spouse or issue survives the Participant, payment shall be made in a single lump
sum to the Participant's estate.

7.5      Unforeseen Emergency

         If a Participant suffers an unforeseen emergency, as defined herein,
the Plan Administrator, in its sole discretion, may pay to the Participant only
that portion, if any, or the vested portion of his or her Account that the Plan
Administrator determines is necessary to satisfy the emergency need, including
any amounts necessary to pay any federal, state or local income taxes reasonably
anticipated to result from the distribution. A Participant requesting an
emergency payment shall apply for the payment in writing in a form approved by
the Plan Administrator and shall provide such additional information as the Plan
Administrator may require. For purposes of this paragraph, "unforeseen
emergency" means an immediate and heavy financial need resulting from any of the
following:

         a. expenses that are not covered by insurance and which the Participant
         or his or her spouse or dependent has incurred as a result of, or is
         required to incur in order to receive, medical care;

         b. the need to prevent eviction of a Participant from his or her
         principal residence or foreclosure on the mortgage of the Participant's
         principal residence; or

         c. any other circumstance that is determined by the Plan Administrator
         in its sole discretion to constitute an unforeseen emergency that is
         not covered by insurance and which cannot reasonably be relieved by the
         liquidation of the Participant's assets.

7.6      FORFEITURE OF NON-VESTED AMOUNTS

         To the extent that any amounts credited to a Participant's Account are
not vested at the time such amounts are otherwise payable under Section 7.1 or
7.3, such amounts shall be 

                                       8


<PAGE>   10

forfeited and shall be used to satisfy the Employer's obligation to make
contributions to the Trust under the Plan.

7.7      TAXES

         All federal, state or local taxes that the Plan Administrator
determines are required to be withheld from any payments made pursuant to this
Article 7 shall be withheld.

The Plan Administrator shall have complete control and authority to determine
the rights and benefits and all claims, demands and actions arising out of the
provisions of the Plan of any Participant, beneficiary, deceased Participant, or
other person having or claiming to have any interest under the Plan. The Plan
Administrator shall have complete discretion to interpret the Plan and to decide
all matters under the Plan. Such interpretation and decision shall be final,
conclusive and binding on all Participants and any person claiming under or
through any Participant, in the absence of clear and convincing evidence that
the Plan Administrator acted arbitrarily and capriciously. Any individual(s)
serving as Plan Administrator who is a Participant will not vote or act on any
matter relating solely to himself or herself. When making a determination or
calculation, the Plan Administrator shall be entitled to rely on information
furnished by a Participant, a beneficiary, the Employer or the Trustee. The Plan
Administrator shall have the responsibility for complying with any reporting and
disclosure requirements of ERISA.

8.2      POWERS, DUTIES, PROCEDURES, ETC.

         The Plan Administrator shall have such powers and duties, may adopt
such rules and tables, may act in accordance with such procedures, may appoint
such officers or agents, may delegate such powers and duties, may receive such
reimbursements and compensation, and shall follow such claims and appeal
procedures with respect to the Plan as it may establish.

8.3      INFORMATION

         To enable the Plan Administrator to perform its functions, the Employer
shall supply full and timely information to the Plan Administrator on all
matters relating to the compensation of Participants, their employment,
retirement, death, termination of employment, and such other pertinent facts as
the Plan Administrator may require.

8.4      INDEMNIFICATION OF PLAN ADMINISTRATOR

         The Employer agrees to indemnify and to defend to the fullest extent
permitted by law any officer(s) or employee(s) who serve as Plan Administrator
(including any such individual who formerly served as Plan Administrator)
against all liabilities, damages, costs and expenses (including attorneys' fees
and amounts paid in settlement of any claims approved by the Employer)
occasioned by any act or omission to act in connection with the Plan, if such
act or omission is in good faith.

                            AMENDMENT AND TERMINATION

9.1      AMENDMENTS

         The Employer shall have the right to amend the Plan from time to time,
subject to Section 9.3, by an instrument in writing that has been executed on
the Employer's behalf by its duly authorized officer.

9.2      TERMINATION OF PLAN

         This Plan is strictly a voluntary undertaking on the part of the
Employer and shall not be deemed to constitute a contract between the Employer
and any Eligible Employee (or any other employee) or a consideration for, or an
inducement or condition of employment for, the performance of the services by
any Eligible Employee (or other employee). The Employer reserves the right to
terminate the Plan at any time, subject to Section 9.3, by an instrument in
writing that has been executed on the Employer's behalf by its duly authorized
officer. Upon termination, the Employer may (a) elect to continue to maintain
the Trust to pay benefits hereunder as they become due as if the Plan had not
terminated or (b) direct the Trustee to pay promptly to Participants (or their
beneficiaries) the vested balance of their Accounts. For purposes of the
preceding sentence, in the event the Employer chooses to implement clause (b),
the Account balances of all Participants who are in the employ of the Employer
at the time the Trustee is directed to pay such balances shall become fully
vested and nonforfeitable. After Participants and their beneficiaries are paid
all Plan benefits to which they are entitled, all remaining assets of the Trust
attributable to Participants who terminated employment with the Employer prior
to termination of the Plan and who were not fully vested in their Accounts under
Article 6 at that time shall be returned to the Employer.

9.3      EXISTING RIGHTS

         No amendment or termination of the Plan shall adversely affect the
rights of any Participant with respect to amounts that have been credited to his
or her Account prior to the date of such amendment or termination.

                                  MISCELLANEOUS

10.1     NO FUNDING

         The Plan constitutes a mere promise by the Employer to make payments in
accordance with the terms of the Plan and Participants and beneficiaries shall
have the status of general unsecured creditors of the Employer. Nothing in the
Plan will be construed to give any employee or any other person rights to any
specific assets of the Employer or of any other person. In all events, it is the
intent of the Employer that the Plan be treated as unfunded for tax purposes and
for purposes of Title 1 of ERISA.

10.2     NON-ASSIGNABILITY

         None of the benefits, payments, proceeds or claims of any Participant
or beneficiary shall be subject to any claim of any creditor of any Participant
or beneficiary and, in particular, the same shall not be subject to attachment
or garnishment or other legal process by any creditor of such Participant or
beneficiary, nor shall any participant or beneficiary have any right to
alienate, anticipate, commute, pledge, encumber or assign any of the benefits or
payment or proceeds that he or she may expect to receive, contingently or
otherwise, under the Plan.

10.3     LIMITATION OF PARTICIPANTS' RIGHTS

         Nothing contained in the Plan shall confer upon any person a right to
be employed or to continue in the employ of the Employer, or interfere in any
way with the right of the Employer to terminate the employment of a Participant
in the Plan at any time, with or without cause.

10.4     PARTICIPANTS BOUND

         Any action with respect to the Plan taken by the Plan Administrator or
the Employer or the Trustee or any action authorized by or taken at the
direction of the Plan Administrator, the Employer or the Trustee shall be
conclusive upon all Participants and beneficiaries entitled to benefits under
the Plan.

10.5     RECEIPT AND RELEASE

         Any payment to any Participant or beneficiary in accordance with the
provisions of the Plan shall, to the extent thereof, be in full satisfaction of

                  --------------------------------------------------------
         designated by the Compensation Committee of the Board of Directors.
         -------------------------------------------------------------------

4.       COMPENSATION

         Compensation is used to determine the amount of Elective Deferrals a
Participant can elect. Compensation under the Plan is defined as (select one):

[X]      the Participant's wages, salaries, fees for professional services and
other amounts received (without regard to whether or not an amount is paid in
cash) for personal services actually rendered in the course of employment with
the Employer or an Affiliate to the extent that the amounts are includable in
gross income, including but not limited to commissions paid to salesmen,
compensation for services on the basis of percentage of profits, commissions on
insurance premiums, tips, bonuses, fringe benefits, reimbursements, and expense
allowances, but not including those items excludable from the definition of
compensation under Treas. Reg. section 1.415-2(d)(3).

[ ]      the regular or base salary payable to the individual by the Employer or
an Affiliate, excluding commissions and bonuses.

[ ]      the  cash  compensation  payable  to the  individual  by  the  Employer
or an  Affiliate,  including  any commissions and bonuses.

[  ]     the cash bonuses payable to the individual by the Employer or an 
Affiliate.

         For purposes of the Plan, Compensation will be determined before giving
effect to Elective Deferrals and other salary reduction amounts that are not
included in the Participant's gross income under Code section 125, 401(k),
402(h) or 403(b).

5.       CONTRIBUTIONS

A. ELECTIVE DEFERRALS. Participants may elect to reduce their Compensation and
to have Elective Deferrals credited to their Accounts by making an election
under the Plan (which may be changed each year for later Plan Years as described
in the plan), but no Participant may defer more than 100 % (1%-100%) of his or
                                                     -----
her Compensation for a Plan Year.

B. MATCHING DEFERRALS. If the Employer elects to match Elective Deferrals,
specify the matching rate and indicate the amount of the Participant's Elective
Deferrals that will be 

                                       2

<PAGE>   16

matched. You may also elect to decide each year whether Matching Deferrals will
be made and, if so, what that year's matching rate will be.

                  For example, the Employer may decide to credit a Matching
Deferral of, for example, 50 cents for each dollar of a Participant's Elective
Deferrals, but limit the match to the first 5% of Compensation deferred by the
Participant. If you want to set a maximum dollar amount on the amount of
Elective Deferrals that will be matched, insert the dollar amount and interval
over which the amount is to be measured. For example, you could say that you
will not match Elective Deferrals in excess of $1,000 per month. Matching
Deferrals can be made after each payroll period, monthly, quarterly, or
annually, at the Employer's discretion. Matching Deferrals will be subject to
the vesting schedule selected in Item 6A (select one):

[ ]      No Matching Deferrals will be credited.

         The Employer will credit Matching Deferrals for each Participant equal
to _____% of the first _____% of the Participant's Compensation which is elected
as an Elective Deferral, but no Matching Deferral will be made on Elective
Deferrals in excess of $__________ per (specify time period if applicable).
____________________

[X]       The Employer will decide from year to year whether Matching Deferrals
will be made and will notify Participants annually of the manner in which
Matching Deferrals will be calculated for the subsequent year.

C. Discretionary Incentive Contributions. The Employer may make Discretionary
Incentive Contributions in any amounts the Employer selects. These contributions
will be subject to the vesting schedule selected in Item 6C.

         The Employer will make Discretionary Incentive Contributions under
the Plan.

7.       ACCOUNTS

         The Trustee can either invest each Participant's Account balance as a
separate account (in which case the Trustee, could, but would not be required
to, take into consideration the investment preferences of the Participants) or
invest the Account balances of all Participants as a single fund (in which case
the Trustee could, but would not be required to, take into consideration the
investment preference of the Employer) (select one):

         [  ]     Account balances are to be invested separately.

         [ X]     Account balances are to be invested as a single fund.

8.       RETIREMENT AGE

         The Retirement Age under the Plan is age 70 . A Participant terminating
employment before Retirement Age for reasons other than death or Total and

      Re: Registration Statement on Form S-8 for the Commercial Savings Bank 
          Deferred Compensation Plan

Sir or Madam:

         We have assisted Commercial Bancshares, Inc. (the "Company") with the
preparation and filing of its Registration Statement on Form S-8 with the
Securities and Exchange Commission pursuant to the requirements of the
Securities Act of 1933, as amended, for the registration of shares of the common
stock of the Company, without par value (the "Shares"), issuable pursuant to the
Company's Deferred Compensation Plan (the "Plan").

         In connection with the following opinion, we have examined and have
relied upon such documents , corporate records, certificates, statements and
instruments as we have deemed necessary and appropriate to render the opinion
herein set forth, prepared. We have assumed, with your permission, that all
stock certificates representing the Shares will be prepared, executed by
appropriate officers, and delivered in a manner consistent with the Company's
Articles and Code of Regulations.

         Based upon the foregoing, it is our opinion that when shares are
delivered to the trust created under the Plan in a manner consistent with the
terms of the Plan, the Shares will be validly authorized and issued, fully paid
and nonassessable.

         In addition, we note that the Plan is an unfunded "top-hat" plan
maintained primarily to provide deferred compensation benefits for a select
group of management or highly compensated employees within the meaning of
Department of Labor Regulation section 2520.104-23, and is therefore exempt from
the reporting and disclosure, minimum participation and vesting, minimum funding
and related requirements of ERISA.

         The undersigned hereby consents to the filing of this opinion as
Exhibit 5.1 to the Registration Statement.


                                               Very truly yours,




                                               SHUMAKER, LOOP & KENDRICK, LLP

                       CONSENT OF INDEPENDENT ACCOUNTANTS

We consent to the incorporation by reference in this Registration Statement on
Form S-8 of Commercial Bancshares, Inc. of our report dated January 23, 1998,
related to the consolidated balance sheets of Commercial Bancshares, Inc. and
the related statements of income, shareholders' equity and cash flows for the
years then ended, which report is included in the Annual Report on Form 10-KSB
of Commercial Bancshares, Inc. for the fiscal year ended December 31, 1997.
