ITEM 1.  BUSINESS.

(a)  RECENT DEVELOPMENT

        On June 15, 1998, the Company entered into an Agreement and Plan of
Merger with KeyCorp pursuant to which the Company will be acquired by KeyCorp.
Under the terms of the Agreement and Plan of Merger, shareholders of the Company

certain employees of the Company. The merger is expected to close during the
fourth calendar quarter of 1998, subject to approval of the Company's
stockholders, certain regulatory approvals and certain other conditions to
closing. Additional information regarding the proposed merger can be found in

1998.

this Report, the "Company" refers, unless the context requires otherwise, to
McDonald & Company Investments, Inc. and its subsidiaries. McDonald & Company
Investments, Inc. conducts substantially all of its business through its
principal subsidiary, McDonald & Company Securities, Inc. ("McDonald
Securities"), which operates a regional investment banking, investment advisory
and brokerage business. The Company also provides personal trust services
through its wholly-owned subsidiary, McDonald Trust Company. The Company also
provides asset management services through its Gradison & Company division
("Gradison").

        The Company's executive offices are located at McDonald Investment
Center, 800 Superior Avenue, Cleveland, Ohio 44ll4-2603 and its telephone number
is (216) 443-2300. The Company has 23 other offices in Ohio (including the

(c)  INDUSTRY SEGMENT DATA

        The Company is engaged in one line of business, that of a securities

(d)  NARRATIVE DESCRIPTION OF BUSINESS

GENERAL
-------

        The Company, through its principal subsidiary, McDonald Securities,
operates a regional investment banking and brokerage business. The Company's
activities include the origination, underwriting, distribution, trading and
brokerage of fixed income and equity securities, investment advisory services,
and investment research and other related services. On July 20, 1983, the
Company succeeded to the business of McDonald & Company, a partnership, which
was established in 1927. The Company has expanded to its present size primarily
through internal growth rather than by acquisition, except for the merger with
Gradison in October 1991.

        The Company serves institutional customers which are located throughout
the United States and in Canada, Europe, and the Far East. The Company's retail
(individual) customers are primarily located in the tri-state region of Ohio,
Michigan and Indiana. For the fiscal year ended March 28, 1998, approximately
51% of total revenues were derived from retail customers, 18% from institutional
customers, 23% from non-customer related principal transactions, investment
banking fees and other activities and 8% from interest and dividend income.

        The Company has formulated a comprehensive strategic plan, which is
periodically reviewed and revised as business conditions dictate. The plan
emphasizes the Company's historical roots as a regional brokerage and investment
banking firm. The Company has focused on the Ohio, Michigan and Indiana area by
increasing the number of investment brokers covering individual investors, as
well as increasing investment banking activities in the region.

ITEM 1.  BUSINESS-- Continued


UNDERWRITING AND INVESTMENT BANKING
-----------------------------------


        McDonald Securities participates in corporate and municipal securities
distributions as a manager or co-manager of an underwriting syndicate or as a
member thereof, or as a member of a selling group. Municipal securities are
obligations issued by state and local governments, hospitals, public utility
systems and industrial development authorities.

        Revenues from underwriting and investment banking activities are highly
dependent on general market conditions for such business activities. Market
conditions for underwriting and investment banking services can be affected by
political and economic events both in the United States and abroad. To the
extent future events are unpredictable, uncertainty will be a factor in the
level of McDonald's business activity. Also, competitive pressure from other
investment bankers has an effect on the success of McDonald Securities in
obtaining such business and on the prices which can be charged for investment
banking and underwriting services. The management of McDonald Securities
believes it can compete effectively in this segment of its business activities.

        Participation in an underwriting syndicate or selling group involves
both economic and regulatory risks. An underwriter or selling group member may
incur losses if it is forced to resell the securities it is committed to
purchase at less than the agreed purchase price. In addition, under the federal
securities laws, other statutes and court decisions with respect to
underwriters' liabilities and limitations on indemnification of underwriters by
issuers, an underwriter is subject to substantial potential liability for
material misstatements or omissions in prospectuses and other communications
with respect to underwritten offerings. Further, underwriting or selling
commitments constitute a charge against net capital, and the Company's
underwriting or selling commitments may be limited by the requirement that it
must at all times be in compliance with the net capital rule. See "Net Capital
Requirements."

        In addition to its underwriting and selling group activities, McDonald
Securities engages in structuring, managing and marketing private offerings of
corporate and municipal securities, and assists in arranging mergers,
acquisitions, divestitures, lease financing and venture capital financing. The
Company provides valuation and financial consulting services for gift and estate
tax purposes, employee stock ownership trusts, mergers, acquisitions, stock
purchase agreements, and other corporate purposes, as well as valuations for
public companies in the process of going private.

        McDonald Securities also markets investments in real estate, primarily
qualified low-income housing tax credit funds, and similar ventures. These
investments generally are in the form of limited partnership interests, which
are primarily marketed to institutional investors. In most cases McDonald
Securities originates such programs, and other subsidiaries of the Company may
act as a general partner.


PRINCIPAL TRANSACTIONS
----------------------

        McDonald Securities actively engages in trading as principal in various
phases of the over-the-counter securities business. To facilitate trading by its
customers, McDonald Securities buys, sells and maintains inventories of
municipal bonds, corporate bonds, government bonds, mortgage-backed securities,
common stocks and preferred stocks in order to "make markets" in those
securities. Revenues from principal transactions depend upon the general trend
of prices and level of activity in the securities market, the skill of employees
in market-making areas and the size of the inventories. Activities in trading as
a principal require the commitment of capital and create an opportunity for
profit and risk of loss due to market fluctuations. As of March 27, 1998,
McDonald Securities made markets in the common stock or other equity securities
of approximately 215 NASDAQ-quoted corporations, as well as other corporations
with less actively traded securities. McDonald Securities has acted as a
managing underwriter for and provides research coverage of certain of these
corporations.

ITEM 1.  BUSINESS-- Continued

        In executing customers' orders to buy or sell in the over-the-counter
market in a security in which it makes a market, McDonald Securities sells to or
purchases from its customers at a price which is approximately equal to the
current inter-dealer market price, plus or minus a markup or markdown.
Alternatively, McDonald Securities may act as agent and execute a customer's
purchase or sale order with another broker-dealer which acts as a market-maker
at the best inter-dealer market price available and charge a commission.

        The Securities and Exchange Commission has recently adopted significant
market structure rules under the Securities and Exchange Act of 1934 involving
the handling and execution of customer limit orders. A market maker in
over-the-counter securities is now required to display in their quote the price
and full size of customer limit orders. In addition, market makers are also
required to display in their quote any better priced orders that the market
maker places into an electronic network such as Selectnet or Instinet, unless an
alternative provided by the rule is available. The effect of these rules will be
to narrow spreads on NASDAQ trades and to reduce the potential for trading
profit on dealer to dealer trades. As a result of the implementation of these
rules, McDonald Securities' profitability from trading NASDAQ quoted companies
will be reduced.

        McDonald Securities is a dealer in corporate, mortgage-backed, and
government fixed income securities which are carried in inventory primarily for
distribution to individual and institutional customers. McDonald Securities
buys, sells and positions mortgage-derivative securities and structured notes.
Holdings of high-yield securities are not material. McDonald Securities may
enter into short positions in United States Treasury securities in order to
hedge its interest rate risk related to fixed income securities.

        The Company's securities positions are subject to fluctuations in market
value and liquidity. The Company seeks to minimize the risks associated with
owning securities by monitoring its security positions on an ongoing basis. The
Company marks its securities to market daily. In addition, each trading
department adheres to a risk limit and a capital commitment limit determined by
senior management. Senior management regularly reviews the Company's securities
positions to ensure that these limits are not exceeded.

COMMISSIONS
-----------

        In executing customers' orders to buy or sell listed securities and
unlisted stocks and bonds in which it does not make a market, McDonald
Securities generally acts as an agent and charges a commission which is
competitive within the industry.

INVESTMENT MANAGEMENT FEES
--------------------------

        Revenues from investment management fees include advisory fees from the
Company's mutual funds and money market funds and investment advisory fees
earned related to individual managed accounts.

        Under asset management programs, the Company provides investment
advisory services to individual, corporate and employee benefit plan clients.
Investment advisory fees for the fiscal year ended March 27, 1998 from
individual managed accounts represented approximately 64% of total revenues from
investment management fees.

        As of March 27, 1998, McDonald Securities is the investment advisor to
and the distributor of the following mutual funds: Gradison Cash Reserve Trust,
which is comprised of one portfolio, Gradison U.S. Government Reserves ("GMU", a
money market fund investing in U.S. Government Securities), Gradison Custodian
Trust, which is comprised of one portfolio, Gradison Government Income Fund
("GIF", a U.S. Government Securities income fund), Gradison Municipal Custodian
Trust, which is comprised of one portfolio, Gradison Ohio Tax-Free Fund ("GMO",
a double tax-free income fund for Ohio investors), Gradison Growth Trust, which
is comprised of four portfolios, Gradison Established Value Fund ("EST", a
common stock fund investing in large, established companies), Gradison
Opportunity Value Fund ("OPP", a common stock fund investing in small
companies), Gradison Growth & Income Fund ("GRI", a common stock fund seeking
long-term growth of capital, current income and growth of income) and Gradison
International Fund ("INT", a common stock fund investing in non-United States
companies). All of these funds are diversified, open-end management investment
companies.

</TABLE>


        The investment advisory fees received from these funds are directly
related to the amounts invested in the funds. Accordingly, McDonald Securities'
investment advisory fees from the investment companies would be reduced in the
future if the amounts invested in the funds decrease.

        McDonald Securities also receives reimbursements from the Gradison Funds
for providing such funds with data processing, shareholder services and other
miscellaneous services.


INTEREST AND DIVIDENDS
----------------------

        A significant portion of the Company's pretax income is derived from
interest and dividend income, net of interest expense. The amount of interest
and dividend income is directly impacted by the level of securities owned and
customer margin account balances, and by general fluctuations in interest rates.
Approximately 59% of interest and dividend income represents interest charged to
customers on the amount borrowed to finance margin transactions. The rate of
interest charged to customers is based on the broker's call money rate (the
interest rate on bank loans to brokers secured by firm and customers' margin
account securities) to which an additional amount, up to 2.5%, is added
depending on the size of the debit balance. Approximately 32% of the Company's
interest and dividend income is generated from securities owned. Approximately
4% of the Company's interest and dividend income is generated from securities
borrowed, and the remaining 5% includes interest on notes receivable, dividend
income, and other.

ITEM 1.  BUSINESS--Continued

OTHER
-----

        During the fiscal year ended March 27, 1998, approximately 27% of other
income represented service fees, IRA administration fees, and other
retail-related revenues compared to 29% and 27%, respectively, for the fiscal
years ended in March 1997 and 1996. Approximately 42% of other income
represented transfer agent fees and other fees derived from the Company's money
market and mutual funds compared to 44% and 36%, respectively, for the fiscal
1997 and 1996 years. For the fiscal year ended March 27, 1998, 23% of other
income represented revenues related to certain venture capital investments,
compared to 17% in fiscal 1997 and 24% in fiscal 1996. The Company periodically
invests in venture capital and other investments in the form of limited
partnerships, general partnerships and equity positions. Miscellaneous income
represented 8%, 10% and 13% of other income, respectively, in the fiscal years
ended March 1998, 1997 and 1996.


RETAIL BUSINESS
---------------

        During the fiscal year ended March 27, 1998, approximately 74% of the
Company's total revenues from customers were from individuals. During the fiscal
year ended March 27, 1998, approximately 28% of the revenues from individual
accounts were derived from agency transactions in listed and unlisted
securities. Individual commission rates on agency transactions are based upon a
schedule which is competitive within the securities industry. Discounts from the
schedule may be granted to retail customers on large trades.

        Approximately 30% of revenues from individual customers were derived
from proprietary and nonproprietary mutual funds. These revenues include sales
charges, fees received from the funds under Section 12(b)(1), and advisory fees
and other fee income related to the propriety mutual funds. Approximately 18% of
retail-related revenues are derived from principal transactions in equity and
debt securities. The remaining 24% of retail-related revenues include revenues
from the sale of investment banking products and revenues from the sale of
annuities, life insurance and other products.


INSTITUTIONAL BUSINESS
----------------------

        During the fiscal year ended March 27, 1998, approximately 26% of the
Company's total revenues from customers were from institutions. Institutional
customers include banks, insurance companies, thrift institutions, pension
funds, mutual funds and money managers. During the fiscal year ended March 27,
1998, approximately 41% of the revenues from institutional accounts were derived
from principal transactions, 34% from investment banking and 25% from agency
transactions. Commissions charged on agency transactions on behalf of
institutional customers are on a negotiated basis and represent a significant
discount from the Company's retail commission schedule.


MARGIN ACCOUNTS
---------------

        Customers' transactions in securities are effected on either a cash or
margin basis. Purchases and sales on a cash basis require full payment or
delivery of securities by the designated settlement date, generally the third
business day following the transaction date. McDonald Securities is at risk in
the event a customer fails to settle a trade and the value of the securities
declines (for a customer purchase), or increases (for a customer sale),
subsequent to the transaction date. In a margin account, the customer pays a
portion of the cost of securities purchased and the broker-dealer makes a loan
for the balance, secured by the securities purchased or other securities owned
by the investor. The amount of the loan is subject to the margin regulations
(Regulation T) of the Board of Governors of the Federal Reserve System, NYSE
margin requirements and McDonald Securities' internal policies, which in some
instances are more stringent than Regulation T or NYSE margin requirements.
Currently, in most transactions Regulation T limits the amount loaned to a
customer for the purchase of a particular security to 50% of the purchase price.
In the event of a decline in the market value of the securities in a customer's
margin account, a member firm, under NYSE rules, is required to have the
customer deposit cash or additional securities so that the loan to the customer
is no greater than 75% of the value of collateral securities in the account. In
permitting customers to purchase securities on margin, McDonald Securities is
subject to the risk of a market decline which could reduce the value of its
collateral below the customers' indebtedness.

ITEM 1.  BUSINESS--Continued

SECURITY REPURCHASE ACTIVITIES
------------------------------

        McDonald Securities acts as principal in the purchase and sale to its
customers of securities of the United States Government and its agencies,
including repurchase agreements in such securities. McDonald Securities may
match purchases and sales of these securities and is at risk to the extent that
it does not properly match the contracts or their customers are unable to meet
their obligations, especially during periods of rapidly changing interest rates
and fluctuations in market conditions. All positions are collateralized.
McDonald Securities generally takes physical possession of securities purchased
under agreements to resell. Such agreements provide McDonald Securities with the
right to maintain the relationship between the market value of the collateral
and the receivable. Typically, these contracts are entered into only with
clients of substantial size and credit-worthiness. McDonald Securities also
utilizes securities sold under repurchase agreements as a means of financing
portions of its trading inventories and facilitating hedging transactions.


SECURITIES BORROWING AND LENDING ACTIVITIES
-------------------------------------------

        McDonald Securities borrows securities from other brokers and dealers to
facilitate short sales and clearance and delivery of securities that have been
sold by their customers when such customers fail to deliver securities prior to
settlement date. McDonald Securities also borrows securities to cover short
positions in NASDAQ securities in the ordinary course of business in its
over-the-counter trading operations. McDonald Securities pays to the lending
broker a cash deposit generally equal to 102 percent of the market value of the
securities borrowed and receives interest on the cash deposit. McDonald
Securities is at risk to the extent that the securities it borrows decline in
value and the loaning broker fails to return McDonald Securities' cash deposit.

        When engaging in securities lending activities, McDonald Securities
lends excess customer margin securities to the borrowing broker and collects
cash deposits that collateralize the securities loaned. In securities lending
transactions, McDonald Securities is at risk to the extent that it does not
maintain the relationship between the market value of securities loaned and the
value of the cash deposit held.


RESEARCH SERVICES
-----------------

        McDonald Securities maintains both an equity and fixed income research
staff which concentrates its efforts on regional research services for both
retail and institutional customers. McDonald Securities employs 31 equity
analysts who cover approximately 250 companies, a majority of which maintain
their headquarters in the Midwest. 9 of the 31 analysts are Chartered Financial
Analysts.

        Research services are made available generally without charge to
customers. Research services include the review and analysis of the economy,
general market conditions, industries and specific companies; recommendation of
specific action with regard to industries and specific companies; review of
customer portfolios; the furnishing of information to retail and institutional
customers; and responses to inquiries from customers and investment brokers. In
addition, McDonald Securities purchases several outside research services which
provide its customers with research more national in scope.

        Management believes that a significant portion of its institutional
equity business is attributable to research services. McDonald Securities
provides services to a nationwide institutional base as well as to institutional
clients in Canada, England, Scotland, Germany, Switzerland and the Far East.

COMPETITIVE FACTORS
-------------------

        Considerable consolidation has occurred in the securities industry as
numerous securities firms have either ceased operation or been acquired by other
securities firms, in many cases resulting in firms with greater financial
resources than firms such as McDonald Securities. In addition, a number of
substantial companies (mostly commercial banks) not previously engaged in the
securities business have made investments in and acquired securities firms.
These developments have resulted in significant additional competition for
McDonald Securities. Increasing competitive pressures in the securities industry
are requiring regional firms such as McDonald Securities to offer to their
customers many of the financial services which are provided by much larger
securities firms that have substantially greater resources and may have greater
operating efficiencies than McDonald Securities. 



                                      -9-
<PAGE>   10


ITEM 1. BUSINESS--Continued


        McDonald Securities competes with other securities firms and with banks,
insurance companies, and other financial institutions principally on the basis
of service, product selection, price, location and reputation in local markets.
McDonald Securities operates at a price disadvantage to discount brokerage firms
that do not offer equivalent services. These firms generally effect transactions
at lower commission rates on an "execution only" basis, without offering other
services such as investment advice and research which are provided by
"full-service" brokerage firms such as McDonald Securities. In addition, some
discount brokerage firms have increased the range of services which they offer.
The existence of and anticipated continued increase in the number of discount
brokerage firms and services provided by such firms may adversely affect the
Company.

        Certain institutions, notably commercial banks and thrift institutions,
have become a competitive factor by offering certain investment banking and
corporate and individual financial services traditionally provided only by
securities firms. With the prior approval of the Federal Reserve, securities
subsidiaries of bank holding companies may now underwrite and deal in corporate
debt and equity securities, provided that they comply with certain firewalls and
that the revenues from such activities do not exceed 25 percent of the
securities subsidiary's total revenues. Legislative proposals currently under
consideration would eliminate this limit on such activities and would permit
banks, bank holding companies and their subsidiaries and affiliates to offer
additional services which have traditionally been provided only by securities
and money management firms. While it is presently not possible to predict the
type and extent of competitive services which banks and other institutions
ultimately may offer or the extent to which administrative or legislative
barriers will be repealed or modified, to the extent that such services are
offered on a large scale, securities firms such as McDonald Securities may be
adversely affected.


EMPLOYEES
---------

        The Company has 1,446 employees, of whom 19 have senior managerial
responsibilities, 398 are full-time investment brokers, 365 are engaged in other
production areas, including trading, research, investment banking, and
investment advisory, and 664 are employed in processing securities transactions,
accounting, management information systems, mutual fund services, personnel and
other administrative services.

        Competition among securities firms and other competitors for successful
investment brokers, securities traders, investment bankers and research analysts
is intense. The Company recognizes the importance of hiring, training and
retaining investment brokers. The Company trains new investment brokers who are
required to take examinations given by the NYSE, the NASD and various states in
order to be registered and qualified. The Company also provides ongoing training
programs for investment brokers. The Company has experienced a relatively low
rate of turnover of investment brokers. From time to time, however, the Company
experiences the loss of valuable personnel.

        The Company considers its employee relations to be good and believes
that its compensation and employee benefits, which include medical, life and
disability insurance, and a 401(k) defined contribution and profit-sharing plan,
are competitive with those offered by other securities firms. None of the
Company's employees is covered by a collective bargaining agreement.


REGULATION
----------

        The securities industry in the United States is subject to extensive
regulation under federal and state laws. The Securities and Exchange Commission
(the "Commission") is the federal agency charged with administration of the
federal securities laws. Much of the regulation of broker-dealers, however, has
been delegated to self-regulatory organizations, principally the NASD and the
national securities exchanges. These self-regulatory organizations adopt rules
(which are subject to approval by the Commission) which govern the industry and
conduct periodic examinations of member broker-dealers. Securities firms are
also subject to examination by state securities commissions in the states in
which they are registered. McDonald Securities is currently registered as a
broker-dealer in all states. In addition, McDonald Securities is registered as a
broker-dealer with the Commission.



                                      -10-
<PAGE>   11



ITEM 1.  BUSINESS--Continued

        The regulations to which broker-dealers are subject cover all aspects of
the securities business, including sales methods, trade practices among
broker-dealers, capital structure of securities firms, record-keeping and the
conduct of directors, officers and employees. Additional legislation, changes in
rules promulgated by the Commission and by self-regulatory organizations, or
changes in the interpretation or enforcement of existing laws and rules often
directly affect the method of operation and profitability of broker-dealers. The
Commission and the self-regulatory organizations may conduct administrative
proceedings which can result in censure, fine, suspension or expulsion of a
broker-dealer, its officers or employees. The principal purpose of regulation
and discipline of broker-dealers is the protection of customers and the
securities market rather than protection of creditors and stockholders of
broker-dealers.

        The Company anticipates regulation of the securities industry to
increase and for compliance with regulations to become more difficult. At
present the Company is unable to predict the extent of changes that may be
enacted, or the effect on the Company's business.

        McDonald Securities' Compliance Committee has the responsibility of
performing reviews to provide reasonable assurance that the officers, directors,
and employees comply with the regulatory requirements of the Commission,
self-regulatory agencies, and McDonald Securities' internal requirements.

        McDonald Securities is required by federal law to belong to the SIPC.
When the SIPC fund falls below a certain minimum amount, members are required to
pay annual assessments to restore the fund. The SIPC fund provides protection
for securities held in customer accounts up to $500,000 per customer, with a
limitation of $l00,000 on claims for cash balances.


NET CAPITAL REQUIREMENTS
------------------------

        As a broker-dealer and member of the NYSE, McDonald Securities is
subject to the Uniform Net Capital Rule promulgated by the Commission (Rule
15c3-1) which provides that a broker-dealer doing business with the public shall
not permit its aggregate indebtedness (as defined) to exceed 15 times its net
capital (as defined) or, alternatively, that its net capital shall not be less
than 2% of aggregate debit balances (primarily receivables from customers)
computed in accordance with Rule 15c3-3. The Rule is designed to measure the
general financial integrity and liquidity of a broker-dealer and the minimum net
capital deemed necessary to meet the broker-dealer's continuing commitments to
its customers. Management believes that the alternative method is more directly
related to the level of customer business, therefore McDonald Securities
computes its net capital under the alternative method.

        A broker-dealer may be required to reduce its business if its net
capital is less than 4% of aggregate debit balances and may be prohibited from
expanding its business or declaring cash dividends if its net capital is less
than 5% of aggregate debit balances. In addition, a broker-dealer may be subject
to disciplinary action by the Commission and self-regulatory agencies, such as
the NYSE, including fines, censure, suspension or expulsion.

        Under Rule 15c3-1 a broker-dealer is required to provide advance written
notice to the Commission of any loan, unsecured advance, or withdrawal of equity
capital which exceeds, in any 30 day period, 30% of excess net capital.
Additionally, written notice must be given to the Commission of any loan,
unsecured advance, or withdrawal of equity capital which exceeds, in any 30 day
period, 20% of excess net capital, within two business days subsequent to the
transaction.

     In computing net capital, various adjustments are made to net worth with a
view to excluding assets which are not readily convertible into cash and to a
conservative statement of the other assets such as a firm's position in
securities. Compliance with the Uniform Net Capital Rule may limit those
operations of a firm which require the use of its capital for purposes of
maintaining the inventory required for trading in securities, underwriting
securities and financing customer margin account balances. A significant
operating loss or an extraordinary charge against net capital could adversely
affect the ability of a broker-dealer to expand or even maintain its present
level of business. Net capital and aggregate debit balances change from day to
day. At March 27, 1998, McDonald Securities' net capital was $86,641,000, which
was 32% of its aggregate debit balances and $81,219,000 in excess of the minimum
required net capital.

        The Company's executive office and largest sales office is located in
Cleveland, Ohio. The Company's order entry, trading, investment banking,
research, operations and accounting activities are primarily centralized in the
Cleveland office. The office, which occupies approximately 165,500 square feet
of space, is operated under a lease expiring in 2009. The Gradison Division of
McDonald Securities is located in Cincinnati, Ohio. The Gradison Division
office, which will occupy approximately 151,000 square feet of space effective
July 1, 1998, is operating under a lease expiring in 2008. Personnel at the
Gradison Division are primarily involved in the mutual fund and investment
advisory operations, retail sales, management, and also certain accounting and
administrative functions. The S. J. Wolfe Division was opened in December, 1990
when the Company acquired certain assets and the business of S. J. Wolfe & Co.,
a stock brokerage firm. The S. J. Wolfe Division has an over-the-counter trading
operation.

        The Company believes that at the present time its administrative and
sales office space is adequate and is suitably utilized.

ITEM 3.  LEGAL PROCEEDINGS.

        As is the case with many firms in the securities industry, McDonald
Securities is a defendant or co-defendant in a number of lawsuits alleging
damages, which are ordinary and routine litigation, incidental to the securities
and investment banking business. The Company is contesting the allegations of
the complaints in these cases and believes that there are meritorious defenses
in each of these lawsuits. Some of the proceedings relate to public
underwritings of securities in which McDonald Securities participated as a
member of the underwriting syndicate. The Company is also aware of litigation
against certain underwriters of offerings in which McDonald Securities was a
participant, but where McDonald Securities is not now a defendant. In these
latter cases, it is possible that McDonald Securities may be called upon to
contribute to settlements or judgments.

         In view of the number and diversity of claims against the Company and
the inherent difficulty of predicting the outcome of litigation and other
claims, the Company cannot state with certainty what the eventual outcome of
pending litigation or other claims will be. The Company provides for costs
relating to these matters when a loss is probable and the amount can be
reasonably estimated. The effect of the outcome of these matters on the
Company's future results of operations cannot be predicted because any such
effect depends on future results of operations and the amount and timing of the
resolution of such matters. While it is not possible to predict with certainty,
management believes that the ultimate resolution of such matters will not have a
material adverse effect on the consolidated financial position, liquidity, or
results of operations of the Company.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

           None.
