            QUESTIONS AND ANSWERS ABOUT VOTING AND VOTING PROCEDURES
            --------------------------------------------------------

Q:   WHEN AND WHERE WILL THE ANNUAL MEETING TAKE PLACE?

A:   The Annual Meeting will be held at the Company's office located at 375
     North Front Street, Suite 300 Columbus Ohio 43215, on Thursday, May 13,
     2004, at 3:00 p.m.

Q:   WHAT DO I NEED TO DO NOW?

A:   After carefully reading this Proxy Statement, indicate on your enclosed
     proxy card how you want your Shares to be voted for the election of
     directors and approval of the terms and conditions of certain equity
     compensation grants. Then sign and mail the proxy promptly in the enclosed
     envelope, or vote by phone by using the control number identified on your
     proxy or electronically by Internet in accordance with the instructions on
     your proxy. The proxy will not be used if you attend, and vote at, the
     Annual Meeting in person or if you revoke the proxy prior to the Annual
     Meeting.

Q:   WHAT IS THE DIFFERENCE BETWEEN HOLDING SHARES AS A SHAREHOLDER OF RECORD
     AND AS A BENEFICIAL OWNER?

A:   Many Company shareholders are beneficial owners in that they hold their
     Shares through a stockbroker, bank or other nominee rather than directly in
     their own name. As summarized below, there are some distinctions between
     Shares held of record and those owned beneficially.

     Shareholder of Record. If your Shares are registered directly in your name
     with the Company's transfer agent, you are considered, with respect to
     those Shares, the shareholder of record and this Proxy Statement is being
     sent directly to you by the Company. As a shareholder of record, you have
     the right to grant your proxy directly to the Company or to vote in person
     at the Annual Meeting. The Company has enclosed a proxy card for your use.

     Beneficial Owner. If your Shares are held in a stock brokerage account or
     by a bank or other nominee, you are considered the beneficial owner of the
     Shares held in street name and this Proxy Statement is being forwarded to
     you by your broker or other nominee, who is considered, with respect to
     those Shares, the shareholder of record. As the beneficial owner, you have
     the right to direct your broker or other nominee on how to vote. Your
     broker or other nominee has enclosed a voting instruction card for your
     use. If you are a Company shareholder whose Shares are not registered in
     your own name, you will need additional documentation from your broker or
     other nominee to attend the Annual Meeting and to vote your Shares at the
     Annual Meeting.

Q:   IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
     SHARES FOR ME?

A:   Your broker will vote your Shares only if you provide instructions on how
     to vote. You should follow the directions provided to you by your broker
     regarding how to instruct your broker to vote your Shares.

Q:   MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

A:   Yes. You can change your vote at any time before your proxy is voted at the
     Annual Meeting. If you are the record holder of the Shares, you can do this
     in three ways:

     o    Send the Company a written statement that you would like to revoke
          your proxy; this written notice must be received by the Company prior
          to the date of the Annual Meeting;

     o    Send the Secretary of the Company a new signed and later-dated proxy
          card; this new proxy card must be received by the Company prior to the
          date of the Annual Meeting; or

     o    Attend the Annual Meeting and vote in person; however, your attendance
          alone will not revoke your proxy.

     For Shares held beneficially by you, but not as record holder, you may
     change your vote by submitting new voting instructions to your broker or
     nominee.

                                      -1-


Q:   HOW CAN I VOTE MY SHARES IN PERSON AT THE ANNUAL MEETING?

A:   Shares held directly in your name as the shareholder of record may be voted
     in person at the Annual Meeting. If you choose to attend, please bring the
     enclosed proxy card or proof of identification.

Q:   HOW WILL MY SHARES BE VOTED IF I RETURN A BLANK PROXY CARD?

A:   If you are the record holder of the Shares and you sign and send in your
     proxy and do not indicate how you want to vote, your proxy will be counted
     as a vote in favor of the director nominees and in favor of the proposed
     equity compensation grants.

Q:   WHO CAN ANSWER MY QUESTIONS ABOUT HOW I CAN SUBMIT MY PROXY?

A:   If you have more questions about how to submit your proxy, please call
     James F. Laird, the Company's Secretary, at (614) 255-3353.

            CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
            ---------------------------------------------------------

     The following statements are or may constitute forward-looking statements
within the meaning of the Private Securities Litigation Reform Act of 1995:

     o    Any statements preceded by, followed by or that include the words
          "believes," "expects," "anticipates," "intends," "estimates,"
          "projects" or similar expressions; and

     o    Other statements contained in this Proxy Statement regarding matters
          that are not historical facts.

     Because these forward-looking statements are subject to risks and
uncertainties, actual results may differ materially from those expressed or
implied by the statements. Shareholders are cautioned not to place undue
reliance on these statements, which speak only as of the date of this Proxy
Statement.

     Among the factors that could cause actual results to differ materially are
changes in laws, general economic conditions, fluctuation in interest rates,
increases in costs, level of competition, market acceptance of new and existing
products, capital expenditure amounts and other risks detailed from time to time
in the reports filed by the Company with the Commission.

     The cautionary statements contained or referred to in this Proxy Statement
should be considered in connection with any subsequent written or oral
forward-looking statements that may be issued by the Company or persons acting
on its behalf. Except for its ongoing obligations to disclose material
information as required by the federal securities laws, the Company undertakes
no obligation to release publicly any revisions to any forward-looking
statements to reflect events or circumstances after the date of this Proxy
Statement or to reflect the occurrence of unanticipated events.

                               THE ANNUAL MEETING
                               ------------------

     The Annual Meeting will be held at the Company's office located at 375
North Front Street, Suite 300, Columbus, Ohio 43215, on Thursday, May 13, 2004,
at 3:00 p.m. Only shareholders of record at the close of business on the Record
Date will be entitled to vote at the Annual Meeting.

     The purposes of this Annual Meeting are (1) to elect seven directors to
serve on the Board of Directors for a one-year term; (2) to consider and approve
the terms and conditions upon which the Board of Directors may grant certain
types of equity compensation to Company employees; and (3) to transact such
other business as may properly come before the Annual Meeting or any adjournment
thereof. The Company is not currently aware of any other matters, which will
come before the Annual Meeting.

                                      -2-


     Your proxy, when duly executed and received by the Company will be voted by
the proxies at the Annual Meeting as you direct. A proxy returned without
direction about business to be transacted at the Annual Meeting will be voted in
favor of (1) the election of Dr. Roger D. Blackwell, R. H. Dillon, David P.
Lauer, Dr. James G. Mathias, David R. Meuse, William G. Perkins and Diane D.
Reynolds as directors of the Company and (2) the approval of the terms and
conditions of grants of equity compensation to Company employees. The proxies
will use their best judgment regarding other matters that properly come before
the Annual Meeting.

                              REVOCABILITY OF PROXY
                              ---------------------

     The execution and delivery of the enclosed form of proxy by a shareholder
will not affect a shareholder's right to attend the Annual Meeting and vote in
person. Any shareholder giving a proxy may revoke it at any time before it is
exercised by delivering a later-dated proxy or a written notice of revocation to
the Secretary of the Company at 375 North Front Street, Suite 300 Columbus, Ohio
43215 or by giving notice of revocation at the Annual Meeting. When a
shareholder votes at the Annual Meeting, his or her vote will revoke any proxy
previously granted by the shareholder.

                     VOTING SECURITIES AND PRINCIPAL HOLDERS
                     ---------------------------------------

    As of the Record Date, there were 1,526,903 Shares that were outstanding and
entitled to vote at the Annual Meeting. Each Share may cast one vote on each
separate matter of business properly brought before the Annual Meeting. There
are no cumulative voting rights.

     Under the rules of the Commission, boxes and a designated space are
provided on the form of proxy for shareholders to mark if they wish to withhold
authority to vote for one or more nominees for election as a director of the
Company and/or if they wish to abstain from voting on the proposal regarding the
equity compensation grants. Shares as to which the authority to vote is withheld
will be counted for quorum purposes but will not be counted toward the election
of directors. Abstentions are counted as present for quorum purposes.

     Broker-dealers who hold their customers' Shares in street name may, under
the applicable rules of the self-regulatory organization of which the
broker-dealers are members, sign and submit proxies for such Shares and may vote
Shares on routine matters, which, under such rules, typically include the
election of directors. However, broker-dealers may not vote Shares on other
matters, such as the approval of the equity compensation grants, which would be
considered non-routine, without specific instructions from the customer who owns
the Shares. Therefore, the Board of Directors encourages shareholders to
instruct their broker-dealer as to how to vote their shares. Proxies signed and
submitted by broker-dealers, which have not been voted on certain matters as
described in the previous sentence, are referred to as broker non-votes. Such
proxies count toward the establishment of a quorum.

                                     QUORUM
                                     ------

     The Company can conduct business at the Annual Meeting only if holders of a
majority of the outstanding Shares entitled to vote are present, either in
person or by proxy. Abstentions will be counted in determining whether a quorum
has been reached. In the event that a quorum is not present at the time the
Annual Meeting is convened, a majority in interest of the holders of the Shares
represented in person or by proxy may adjourn the Annual Meeting, without notice
other than announcement at the Annual Meeting, until holders of the amount of
Shares requisite to constitute a quorum shall attend. At any such adjourned
Annual Meeting at which a quorum shall be present, any business may be
transacted which might have been transacted at the Annual Meeting as originally
called.

     The Company will bear the cost of the Annual Meeting and the cost of
soliciting proxies, including the cost of mailing the proxy material. In
addition to solicitation by mail, directors, officers and employees of the
Company (who will not be specifically compensated for such services) may solicit
proxies by telephone or otherwise.

     No person is authorized to give any information or to make any
representation not contained in this Proxy Statement, and if given or made, such
information or representation should not be relied upon as having been
authorized. This Proxy Statement does not constitute the solicitation of a proxy
in any jurisdiction from any person to whom it is unlawful to make such proxy
solicitation in such jurisdiction. The delivery of this Proxy Statement shall

                                      -3-


not, under any circumstances, imply that there has not been any change in the
information set forth herein since the date of this Proxy Statement.

         SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
         --------------------------------------------------------------

     The Company's Common Stock is the only class of voting securities. The
following table sets forth, as of December 31, 2003, certain information
concerning share ownership of (a) all persons known by the Company to own
beneficially five percent or more of the outstanding Shares, (b) each director,
nominee and named executive officer of the Company, and (c) all executive
officers and directors of the Company, as a group, and the percentage of voting
power (assuming exercise of all options which are currently exercisable). Unless
otherwise indicated, the named persons exercise sole voting and investment power
over the Shares, which are shown as beneficially owned by them.

                         COMMITTEES AND ANNUAL MEETINGS
                         ------------------------------

     The Board of Directors held a total of five meetings during the year ended
December 31, 2003. The Board of Directors has two standing committees: the
Executive Committee and the Audit Committee. Each Director attended at least 75%
of the aggregate of (a) the total number of Board of Directors' meetings held
during the period for which he or she has been a Director during the last fiscal
year, and (b) the total number of meetings held by all committees of the Board
of Directors on which he or she served during the periods that he or she served
during the last fiscal year. The Company does not have a formal policy regarding
board members' attendance at annual meetings, although all directors are
encouraged to attend the annual meeting. Last year, all directors attended the
annual meeting.

     EXECUTIVE COMMITTEE

     The Executive Committee is authorized, when it is impractical or not in the
best interest of the Company to wait until a Board of Directors meeting for
approval, to take any and all action or incur any obligations which could be
taken or incurred by the full Board of Directors. The members of the Executive
Committee as of December 31, 2003, were David R. Meuse (Chairman), Dr. Roger D.
Blackwell and Dr. James G. Mathias. The Executive Committee did not hold any
meetings during the year ended December 31, 2003.

     DIRECTOR NOMINATION PROCESS

     Given the relatively small size of the Company and its Board of Directors,
the Company does not believe that a standing nominating committee is necessary.
All of the Company's directors participate in the consideration of director
nominees. Although the Company does not have a formal charter governing the
nomination of directors, it does have an explicit list of criteria that the
Board uses to assess potential directors. It is the Company's expectation that
candidates for the Board of Directors will at the least possess significant
skill and experience in financial services, accounting, marketing, operations,
legal matters and in other areas that are important to the success of the
Company.

     Director nominees are recommended for the Board's selection by any of the
members of the Board of Directors, a majority of whom are independent. The
Company will consider director candidates recommended by shareholders, and the
Company does not alter the manner in which it evaluates candidates, including
the minimum criteria set forth above, based upon the source of the director
nomination.

                                      -7-


     AUDIT COMMITTEE

     The Audit Committee reviews and approves the scope and results of any
outside audit of the Company and the fees therefore and makes recommendations to
the Board of Directors or management concerning auditing and accounting matters
and the selection of independent auditors. The Audit Committee also conducts
appropriate reviews of all related party transactions for potential conflicts of
interest situations on an ongoing basis, and all such transactions are approved
by the Audit Committee. The Audit Committee's responsibilities are outlined
further in its written charter, a copy of which is attached to this Proxy
Statement as Exhibit A. Each member of the Audit Committee qualifies as
independent under the rules and standards of independence of the Securities and
Exchange Commission (the "SEC") and The NASDAQ Stock Market, Inc. ("Nasdaq").
The Board has determined that the Chairman of the Audit Committee, David P.
Lauer, qualifies as a "financial expert" as defined by applicable rules of the
SEC and as "financially sophisticated" as defined by applicable Nasdaq rules.
The Audit Committee met four times during the year ended December 31, 2003 and
its report relating to the Company's 2003 fiscal year appears below.

                          REPORT OF THE AUDIT COMMITTEE
                          -----------------------------
                               (December 31, 2003)

     Notwithstanding anything to the contrary set forth in the Company's
previous filings under the Securities Act of 1933, as amended (the "Securities
Act"), or the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
that might incorporate future filings, including this Proxy Statement, in whole
or in part, this report shall not be incorporated by reference into any such
filings.

     The Audit Committee in 2003 was comprised of three independent directors
operating under a written charter adopted by the Board of Directors. Annually,
the Audit Committee recommends to the Board of Directors the selection of the
Company's independent auditors. BKR Longanbach, Giusti, LLC served as the
Company's independent auditors during the year ended December 31, 2003.

     Management is responsible for designing and maintaining the Company's
systems of internal controls and financial reporting processes. The Company's
independent auditors are responsible for performing an audit of the Company's
consolidated financial statements in accordance with generally accepted auditing
standards and issuing their report thereon. The Audit Committee's responsibility
is to provide independent, objective oversight of these processes.

     Pursuant to this responsibility, the Audit Committee met with management
and the independent auditors throughout the year. The Audit Committee reviewed
the audit plan and scope with the independent auditors, and discussed the
matters required by Statement on Auditing Standards No. 61 (Communication with
Audit Committees). The Audit Committee also met with the independent auditors,
without management present, to discuss the results of their audit work, their
evaluation of the Company's system of internal controls and the quality of the
Company's financial reporting.

     In addition, the Audit Committee has discussed with the independent
auditors their independence from the Company and its management, including the
matters in written disclosures and letters from the independent auditors
required by the Independence Standards Board Standard No.1 (Independence
Discussions with Audit Committees).

     Management has represented to the Audit Committee that the Company's
consolidated financial statements for the year ended December 31, 2003, were
prepared in accordance with generally accepted accounting principles, and the
Audit Committee reviewed and discussed the consolidated financial statements
with management and the independent auditors. Based on the Audit Committee's
discussions with management and the independent auditors and review of the
report of the independent auditors to the Audit Committee, the Audit Committee
recommended to the Board of Directors (and the Board has approved) that the
audited consolidated financial statements be included in the Company's Form
10-KSB for the year ended December 31, 2003, filed with the Commission.

SUBMITTED BY THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS OF THE COMPANY:

                                        DAVID P. LAUER, CHAIRMAN

___________
(1)  Consists of the 1993 Non-Qualified and Incentive Stock Option Plan.
(2)  Consists of a Warrant to purchase shares of current stock of the Company
     issued to Roderick H. Dillon, Jr. on May 11, 2000. The Warrant originally
     granted Mr. Dillon the right to purchase 1,000,000 shares of common stock
     at a purchase price of $1.60 per share, which terms were automatically
     adjusted as a result of the 1 for 5 reverse stock split in September 2001,
     resulting in Mr. Dillon having the right to purchase 200,000 shares of
     common stock at $8.00 per share.
(3)  The 1993 Stock Option Plan expired by its terms in November 2003.

INCENTIVE COMPENSATION PLAN

     All full-time executive employees of the Company are eligible to
participate in the Company's Incentive Compensation Plan (the "IC Plan"). The IC
Plan provides that a bonus fund will be established in an amount equal to 20% of
the pre-tax realized profits of the Company in excess of a 15% pre-tax return on
equity. The amount of the bonus fund is calculated each fiscal quarter on a
cumulative basis. The allocation of the bonus fund is to be made by the
President of the Company. The Company did not incur any expense under the IC
Plan for the year ended December 31, 2003.

STOCK OPTION PLAN

     The Company's 1993 Non-Qualified and Incentive Stock Option Plan expired by
its terms in November 2003. The Company has no current plans to propose a
replacement or new option plan to the shareholders for approval.

DIRECTOR COMPENSATION

     Each director who is not an employee of the Company is entitled to receive
a fee of $500 plus travel expenses for each directors' meeting attended.

                                      -10-


                       PROPOSAL 1 - ELECTION OF DIRECTORS
                       ----------------------------------

     The Board of Directors of the Company has nominated R. H. Dillon, Dr. Roger
D. Blackwell, David P. Lauer, Dr. James G. Mathias, David R. Meuse, William G.
Perkins and Diane D. Reynolds for election to the Board of Directors of the
Company to hold office for one-year terms in 2004 expiring at the annual meeting
of shareholders. Each such nominee is a member of the existing Board of
Directors.

     The Company's board of directors formed a special Corporate Governance
Committee on August 30, 2001 to examine certain corporate governance issues and
to report to the full board on November 1, 2001. The Corporate Governance
Committee, among other things, recommended that the Company's board be reduced
to as few as six directors and that all but one director should be independent,
as defined by the Nasdaq rules. Based upon that recommendation, the board, at
its February 13, 2003 meeting, nominated seven existing board members, all but
one being independent, for election by shareholders at the 2003 Annual
Shareholder Meeting. The nominations were based upon consideration of factors
that the committee had suggested should be important, including independence,
competence in general business matters, experience and competence in financial,
operational and marketing matters, and willingness to assist the Company in
business development efforts.

     A proposal to elect R. H. Dillon, Dr. Roger D. Blackwell, David P. Lauer,
Dr. James G. Mathias, David R. Meuse, William G. Perkins and Diane D. Reynolds
will be presented to the shareholders at the Annual Meeting. The seven nominees
receiving the highest number of votes will be elected.

     THE COMPANY'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE IN
FAVOR OF R. H. DILLON, DR. ROGER D. BLACKWELL, DAVID P. LAUER, DR. JAMES G.
MATHIAS, DAVID R. MEUSE, WILLIAM G. PERKINS AND DIANE D. REYNOLDS.

         PROPOSAL 2 - APPROVAL OF TERMS AND CONDITIONS OF CERTAIN EQUITY
         ---------------------------------------------------------------
                               COMPENSATION GRANTS
                               -------------------

     Certain of the Company's directors, officers and employees have from time
to time received grants of options to acquire shares of the Company's Common
Stock pursuant to the Company's 1993 Non-Qualified and Incentive Stock Option
Plan (the "Plan"). The Plan by its terms expired in November 2003, which results
in the Company being currently unable, pursuant to applicable rules of the
Nasdaq (subject to certain limited exceptions), to issue any form of equity
compensation to the Company's current directors, officers, employees or
consultants without first obtaining the approval of the Company's shareholders.

     Through a written action taken on March 15, 2004 and upon the
recommendation of management, the Board unanimously approved, subject to
shareholder approval, a limited grant of restricted stock and restricted stock
units to three key Company employees: Chris Bingaman, Tom Schindler and Bill
Zox. Specifically, the Board approved, subject to shareholder approval, a grant
of an aggregate of 75,000 shares of restricted stock and restricted stock units
to those key employees, each of them to receive a combination of 25,000 shares
of restricted stock and restricted stock units. The award of such shares and
units will be made pursuant to the terms contained in the form of the Diamond
Hill Investment Group, Inc. Agreement For Restricted Stock and Restricted Stock
Units attached to this Proxy Statement as Exhibit B.

     Chris, Tom and Bill are each employed by the Company as investment
analysts. In the opinion of both management and the Board, each of Chris, Bill
and Tom has been, and will continue to be, an important part of the Company's
continued improvement and progress towards achieving its long-term performance
goals. In the opinion of management and the Board, retaining Chris, Tom and Bill
on a long-term basis is vital and in the best interests of the Company and its
shareholders. Management and the Board believe that granting the shares of
restricted stock and restricted stock units, as described in greater detail
below, will motivate each of them to remain employed by the Company for at least
the next five years. Therefore, management and the Board recommend that the
shareholders approve these awards.

                                      -11-


Description of Awards

     Pursuant to the Award Agreement, each recipient will receive a total of
25,000 shares of restricted stock and restricted stock units. None of the
recipients will pay any cash or other consideration in exchange for such shares
and units; instead, each recipient must remain employed by the Company up and
through the fifth anniversary of the initial award (subject to limited
accelerated vesting events as described below). Absent an acceleration of the
vesting schedule, a recipient will forfeit all of the shares and units if he
ceases to be employed by the Company prior to the fifth anniversary of the
initial award.

     At the time of the initial award, each recipient will receive 5,000 shares
of restricted stock that will one-time vest on the date that is five years from
the date of the award. Each recipient will also receive a grant of 20,000
restricted stock units, which will vest 20% per year over the next five years.
This will result in each recipient receiving 5,000 shares of restricted stock
upon each anniversary of the initial award date. Those shares of restricted
stock will be subject to a vesting schedule that will result in each grant of
5,000 shares of restricted stock vesting at one time on the fifth anniversary of
the award date. The following table explains this structure further:

     Year   Award                                  Vesting Schedule
     ----   -----                                  ----------------

     2004   5,000 shares of restricted stock       One-time vest in 5 years
            20,000 restricted stock units          25% per year over 4 years

     2005   5,000 shares of restricted stock       One-time vest in 4 years

     2006   5,000 shares of restricted stock       One-time vest in 3 years

     2007   5,000 shares of restricted stock       One-time vest in 2 years

     2008   5,000 shares of restricted stock       One-time vest in 1 year

     2009   None; 25,000 shares of restricted stock fully vested

     As described in the above table, on the fifth anniversary of the initial
award date, each of the recipients will be fully vested in 25,000 shares of the
Company's common stock. Although the shares will at that point be fully vested,
such shares will not be registered under the Securities Exchange Act and will
therefore be considered "restricted securities" pursuant to SEC Rule 144.

Value of Awards

     Because of the structure of the awards to Chris, Tom and Bill the current
value of the awards is not determinable; as the Company is unable to project the
value of shares of restricted stock to be awarded, and that vest, at some future
date. As of December 31, 2003, the closing price of the Company's common stock
was $6.94 per share. Based upon an assumption that the shares of restricted
stock awarded to the recipients (i) were awarded all at one time instead of over
a five-year period, (ii) were fully vested at the time of the award, (iii) not
"restricted securities" pursuant to SEC Rule 144 and therefore able to be
disposed of in open market transactions and (iv) the volume for the Company's
common stock were sufficiently high to permit a liquidation of the awarded
stock, and using the closing price as of December 31, 2003, the value of the
award to each recipient would be $173,500.

Other Material Terms of Award

Dividend and Voting Rights
--------------------------

     Although the shares of restricted stock, when granted, will remain subject
to the vesting schedule described above, the recipients will be entitled upon
receipt of the awards to full voting and dividend rights (to the extent that the
Company were to declare a dividend). Other than dividend and voting rights,
until such shares are fully vested the recipients will have no other rights as
shareholders pursuant to the Company's Articles of Incorporation or Code of
Regulations or by applicable law.

                                      -12-


Acceleration of Vesting
-----------------------

     Upon the occurrence of certain events or conditions described below, the
vesting schedule described above may be accelerated, such that all shares of
restricted stock then held by a recipient will immediately vest in full, and any
restricted stock units then held by the recipient will immediately vest, as will
the shares of restricted stock issued upon the vesting of the restricted stock
units. In other words, upon an acceleration of the vesting schedule, a recipient
shall immediately be fully vested in 25,000 shares of restricted stock.

     Acceleration of vesting will, or in the case of number five below, may,
occur upon the following, each as defined in the Award Agreement:

     1.   A "Change of Control" of the Company;
     2.   The termination of the employment of the employee by the Company
          without "Cause";
     3.   The termination of the employment of the employee by the employee for
          "Good Reason";
     4.   The death or disability of the employee as defined in the Internal
          Revenue Code; or
     5.   At such time and upon such terms as the Board in its discretion
          determines.

Forfeiture Upon Termination of Employment
-----------------------------------------

     Unless the vesting schedule is accelerated as described above, in the event
that Chris, Tom or Bill terminates his employment with the Company without Good
Reason, or if such employment is terminated by the Company with Cause, prior to
the fifth anniversary of the initial award, all of the shares of Restricted
Stock then held by him shall be deemed repurchased by the Company for the
purchase price paid by him (which is $0), and each unvested Restricted Stock
Unit then held by him will be cancelled.

Adjustments to Number of Shares and Units
-----------------------------------------

     The number of shares of restricted stock and restricted stock units granted
to each recipient will be appropriately adjusted to reflect any stock split,
stock dividend or other change in the Company's capital stock which may be made
after the date of the initial award.

Amendments to Award
-------------------

     Under current applicable rules of the Nasdaq (or such other system or
exchange upon which the Company's shares are then traded), the award agreements
cannot be materially amended without shareholder approval. Other than (i)
amendments that the Company reasonably believes are not material and (ii) the
acceleration and adjustment provisions described above, the award agreements are
by their terms not able to be materially amended without shareholder approval,
if such approval would then be required by applicable law, rules or regulations.

Federal Income Tax Consequences of Award

     The following is a brief summary of the general federal income tax
consequences of the awards described above based on federal income tax laws in
effect as of April 12, 2004. This summary is not intended to be exhaustive and
does not describe any foreign, local or state tax consequences.

     RESTRICTED STOCK. Unless a recipient makes an election under Section 83(b)
of the Internal Revenue Code, restricted stock awards are not included in his
income until the award vests. At vesting, the recipient is taxed, at ordinary
income rates, on the fair market value of the stock on the vesting date. Any
subsequent appreciation in the stock price would be taxed at capital gains
rates, assuming the stock has been held for a period of more than one year from
the date of vesting.

     Within thirty days of receipt of a restricted stock award, a recipient may
elect, under Section 83(b), to include in ordinary income on the date of receipt
of the restricted stock the fair market value of the stock (without taking into
account any restrictions other than those which by their terms never lapse). Any
subsequent appreciation would then be eligible for capital gain treatment,
assuming the stock has been held for a period of more than one year from the
date of the grant.

                                      -13-


     In general, the Company is entitled to a deduction equal to the amount
included in the recipient's ordinary income in the year in which such amount is
reported for tax purposes by the recipient, provided the Company satisfies
applicable withholding and reporting requirements.

     RESTRICTED STOCK UNITS. As restricted stock units are unfunded and
unsecured promises to issue restricted stock at a future date, a grant of
restricted stock units is not a taxable event to the recipient. Once a
restricted stock unit award vests and the recipient receives restricted stock,
the federal income tax consequences described above will apply to the award of
restricted stock.

     THE COMPANY'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE IN
FAVOR OF PROPOSAL TWO.

                COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT
                -------------------------------------------------

     Section 16(a) of the Exchange Act requires executive officers and directors
of the Company, and persons who beneficially own more than ten percent (10%) of
the Shares, to file initial reports of ownership and reports of changes in
ownership with the Commission. Executive officers, directors and persons who
beneficially own more than ten percent (10%) of the Shares are required by
Commission regulations to furnish the Company with copies of all Section 16(a)
reports they file. Based solely upon a review of Forms 3 and 4 furnished to the
Company, management of the Company believes that there were no reports filed
late during the year ended December 31, 2003.

                       EXPENSE AND MANNER OF SOLICITATION
                       ----------------------------------

     The expenses of the solicitation of the proxies for the Annual Meeting,
including the cost of preparing, assembling and mailing the Notice, form of
proxy, Proxy Statement and return envelopes, the handling and tabulation of
proxies received, and charges of brokerage houses and other institutions,
nominees or fiduciaries for forwarding such documents to beneficial owners, will
be paid by the Company. In addition to the mailing of the proxy material,
solicitation may be made in person or by telephone by officers or directors of
the Company (none of whom have been employed to specifically solicit
shareholders).

                                   FORM 10-KSB

                              --------------------

     The Company has selected BKR Longanbach, Giusti, LLC as the Company's
independent auditors for the 2004 fiscal year and to audit the financial
statements of the Company for the year ended December 31, 2003. A representative
of BKR Longanbach, Giusti, LLC is expected to be present to respond to

                                              ==========    ==========

     It is the policy of the Audit Committee to pre-approve the services of the
independent accountants and present that approval to the Board of Directors. For
the years ended December 31, 2003 and 2002, 100% of the independent accountants'
fees were pre-approved by the Audit Committee

                                      -14-


                  SHAREHOLDER PROPOSALS FOR 2005 ANNUAL MEETING
                  ---------------------------------------------

     Shareholders are entitled to submit proposals on matters appropriate for
shareholder action consistent with Commission regulations and the Company's
bylaws. Should a shareholder wish to have a proposal appear in the Company's
Proxy Statement for next year's annual meeting, under the regulations of the
Commission, the proposal must be received by the Secretary of the Company at 375
North Front Street Columbus, Ohio 43215, on or before December 10, 2004. If a
shareholder intends to present a proposal at next year's annual meeting but does
not intend to seek the inclusion of such proposal in the Company's Proxy
Statement, such proposal must be received by the Company prior to February 25,
2005, or the Company's management proxies will be entitled to use their
discretion voting authority should such proposal be raised without any
discussion of the matter in the Proxy Statement.

         COMMUNICATIONS BETWEEN SHAREHOLDERS AND THE BOARD OF DIRECTORS
         --------------------------------------------------------------

     The Company does not have a formal process for shareholders to send
communications to the board of directors. Given the relatively small size of the
Company and its Board of Directors, the relatively small number of record
holders of the Company's shares, and the Board's consistent practice of being
open to receiving direct communications from shareholders, the Company believes
that it is not necessary to implement a formal process for shareholders to send
communication to the Board. The Company's practice is to forward any
communication addressed to the Board of Directors to the members of the Board.

                       CODE OF BUSINESS CONDUCT AND ETHICS
                       -----------------------------------

     At a regular Company board of directors meeting on February 5, 2004 the
board unanimously approved a Code of Business Conduct and Ethics that applies to
all directors, officers and employees. A copy of this Code is attached to this
Proxy Statement as Exhibit C.

                                 OTHER BUSINESS
                                 --------------

     The Board of Directors knows of no other business to be acted upon at the
Annual Meeting. However, if any other business properly comes before the Annual
Meeting, it is the intention of the persons named in the enclosed Proxy to vote
on such matters in accordance with their best judgment.

     The prompt completion, execution, and delivery of your Proxy will be
appreciated. Whether or not you expect to attend the Annual Meeting, please
complete and sign the Proxy and return it in the enclosed envelope, or vote your
proxy electronically via the Internet or telephonically.
