                            PARKWAY PROPERTIES, INC.
                                  COMMON STOCK
 
     This Prospectus Supplement relates to the offering and sale of 855,900
shares (the "Shares") of common stock, par value $0.001 per share (the "Common
Stock"), of Parkway Properties, Inc. ("Parkway" or the "Company") to one or more
institutional investors at a purchase price per share of $32.1875, for an
aggregate purchase price of approximately $27.5 million (the "Offering"). On
March 5, 1998, the reported last sale price of the Common Stock on the New York
Stock Exchange, Inc. ("NYSE") was $32.1875 per share. The Common Stock is, and
the Shares will be, listed on the NYSE under the symbol "PKY."
 
     In connection with the Offering, the Company has agreed to pay a fee in the
amount of approximately $550,986 to PaineWebber Incorporated ("PaineWebber") for
its services as a finder in connection with the Shares to be sold in the
Offering. Such fee represents, on a weighted average basis, approximately 2% of
the gross proceeds of the sale of the Shares in the Offering. In addition, the
Company has agreed to indemnify PaineWebber against certain liabilities,
including liabilities under the Securities Act of 1933, as amended (the
"Securities Act"). See "Plan of Distribution."
 
     Parkway is a self-administered real estate investment trust ("REIT")
specializing in the acquisition, ownership, management, financing and leasing of
office properties in the Southeastern United States and Texas. Parkway and its
predecessors have been public companies engaged in the real estate business
since 1971, and have successfully operated and grown through several major real
estate cycles. As of March 2, 1998, Parkway owned or had an interest in 46
office properties in 12 states encompassing approximately 6.3 million net
rentable square feet (the "Properties"). The Company seeks to acquire Class A,
A- or B+ office properties ranging in size from 50,000 to 500,000 net rentable
square feet in markets characterized by above average employment and population
growth.

                                  THE COMPANY
 
     Parkway is a self-administered REIT specializing in the acquisition,
ownership, management, financing and leasing of office properties in the
Southeastern United States and Texas. Parkway and its predecessors have been
public companies engaged in the real estate business since 1971, and have
successfully operated and grown through several major real estate cycles. As of
March 2, 1998, Parkway owned or had an interest in 46 office properties in 12
states encompassing approximately 6.3 million net rentable square feet. The
Company seeks to acquire Class A, A- or B+ office properties ranging in size
from 50,000 to 500,000 net rentable square feet in markets characterized by
above average employment and population growth.
 
     The purchase of the Mtel Centre in Jackson, Mississippi in July 1995 marked
the implementation of the Company's business strategy of focused investment in
office properties. As part of this strategy, the Company has (i) completed the
acquisition of 42 office properties, encompassing approximately 5.9 million net
rentable square feet, for a total investment (as defined herein) of more than
$517.3 million; and (ii) sold or is in the process of selling all of its
non-office assets.
 
     Parkway generally seeks to purchase office properties at significant
discounts to replacement cost, and whose current rental rates are at or below
market rental rates. Since January 1, 1997, the Company has acquired 30 office
properties aggregating approximately 4.3 million net rentable square feet for a
total investment of approximately $412.6 million, or approximately $96 per net
rentable square foot. Total investment is defined as purchase price plus
estimated closing costs plus anticipated capital expenditures during the first
24 months of ownership for tenant improvements, commissions, upgrades and
capital improvements to bring the building up to the Company's standards.

                                  RISK FACTORS
 
FAILURE TO MANAGE RAPID GROWTH AND INTEGRATE OPERATIONS
 
     Parkway is currently experiencing a period of rapid growth. Parkway has
acquired 30 office properties with approximately 4.3 million net rentable square
feet since January 1, 1997 (the "Recent Acquisitions"). The integration of the
Recent Acquisitions into existing management and operating structures presents a
significant management challenge. Although Parkway believes it has sufficient
management depth to lead Parkway through this period of rapid growth, there can
be no assurance that Parkway will be able to assimilate the Recent Acquisitions
or any further acquisitions into its portfolio without certain operating
disruptions and unanticipated costs. The failure to successfully integrate the
Recent Acquisitions could have a material adverse effect on the results of
operations and financial condition of Parkway and its ability to pay expected
distributions to stockholders. Also, Parkway is evaluating many potential
acquisitions, the process of which involves costs which are non-recoverable.
There can be no assurance that properties which are acquired will perform in
accordance with expectations or that cost estimates for improvements to the
acquired properties in order to bring them up to the Company's standards will be
accurate. In addition, Parkway has expanded its current self-management for
office properties it owns or may acquire in Houston, Atlanta, Dallas, Charlotte,
Winston-Salem, Columbia and Memphis. There can be no assurance that the cost
benefits anticipated in connection with such self-management will be achieved or
that Parkway will successfully integrate the operational structure necessary for
the self-management of such properties.
 
REAL ESTATE FINANCING RISKS
 
     The required repayment of debt or interest thereon could adversely affect
Parkway's financial condition. Parkway is subject to the risks normally
associated with debt financing, including the risk that Parkway's cash flow will
be insufficient to meet required payments of principal and interest, the risk of
violating loan covenants, the risk of rising interest rates on Parkway's
variable rate debt and the risk that Parkway will not be able to repay or
refinance existing indebtedness on its Properties at maturity (which generally
will not have been fully amortized at maturity) or that the terms of such
refinancing will not be as favorable as the terms of existing indebtedness.
There can be no assurance that Parkway will be able to refinance any
indebtedness it may incur or otherwise obtain funds by selling assets or raising
equity to make required payments on indebtedness.
 
     As of March 2, 1998, 13 of the Properties secured non-recourse mortgage
indebtedness totaling approximately $104.5 million, seven of the Properties
secured the Company's acquisition revolving credit facility (the "Acquisition
Facility"), a building owned by a partnership in which Parkway is a 50% partner
secured mortgage indebtedness of approximately $816,000, and negative pledges
with respect to 13 of the Recent Acquisitions were in place for approximately
$75.0 million of indebtedness under a line of credit with NationsBank, NA (the
"February Facility"). In addition, properties which Parkway may acquire in the
future could be mortgaged to secure payment of indebtedness. If Parkway is
unable to generate funds to cover required payments of principal and interest on
borrowings secured by any of these properties, the mortgage securing such
properties could be foreclosed upon by, or such properties could otherwise be
transferred to, the mortgagee with a consequent loss of income and asset value
to Parkway.
 
     Rising interest rates could adversely affect Parkway's cash flow. Advances
under the Acquisition Facility, the February Facility and the Company's working
capital revolving credit facility (the "Working Capital Facility") will bear
interest at variable rates. In addition, Parkway may incur indebtedness in the
future that also bears interest at a variable rate or may be required to
refinance its debt at higher rates. Accordingly, increases in interest rates
could increase Parkway's interest expense, which could adversely affect
Parkway's financial condition and ability to pay expected distributions to
stockholders.
 
Parkway's organizational documents contain no limitation on debt which could
adversely affect Parkway's cash flow. Parkway currently has a policy of
maintaining what the Company believes to be conservative leverage. As of March
5, 1998, on an as adjusted basis assuming the completion of the Offering and the
application of the net proceeds therefrom, Parkway's ratio of debt to total
market capitalization was approximately 40.4%. Also as of March 5, 1998, on an
as adjusted basis assuming the completion of the
                                       S-3
<PAGE>   4
 
Offering and the application of the net proceeds therefrom, Parkway had
outstanding consolidated indebtedness of approximately $241.4 million, all of
which is secured and approximately $104.5 million of which is fixed rate
indebtedness. As of March 5, 1998, on an as adjusted basis assuming the
completion of the Offering and the application of the net proceeds therefrom,
there was approximately $58.1 million outstanding under the Acquisition
Facility, approximately $3.8 million outstanding under the Working Capital
Facility and approximately $75.0 million outstanding under the February
Facility. Parkway's organizational documents do not contain any limitation on
the amount of indebtedness it may incur. Accordingly, the Board of Directors
could alter or eliminate its current debt policy and would do so, for example,
if it were necessary in order for Parkway to continue to qualify as a REIT. If
this policy were changed, Parkway could become more highly leveraged, resulting
in an increase in debt service that could adversely affect Parkway's financial
condition and cash available for distribution to stockholders and could increase
the risk of default on Parkway's indebtedness.
 
REAL ESTATE INVESTMENT RISKS
 
     General Risks.  Parkway's investments generally consist of investments in
office buildings and as such will be subject to varying degrees of risk
generally incident to the ownership of real property. The underlying value of
Parkway's real estate investments and Parkway's financial condition and ability
to make expected distributions to its stockholders will be dependent upon its
ability to operate the Properties in a manner sufficient to maintain or increase
revenues and to generate sufficient income in excess of operating expenses.
Income from the Properties may be adversely affected by changes in national
economic conditions, changes in local market conditions due to changes in
general or local economic conditions and neighborhood characteristics, changes
in interest rates and in the availability, cost and terms of mortgage
financings, the impact of present or future environmental legislation and
compliance with environmental laws, the ongoing need for capital improvements,
particularly in older structures, changes in real estate tax rates and other
operating expenses, adverse changes in governmental rules and fiscal policies,
adverse changes in zoning laws, civil unrest, acts of God, including earthquakes
and other natural disasters (which may result in uninsured losses), acts of war
and other factors which are beyond the control of Parkway.
 
     Dependence on Primary Markets.  Substantially all of the Properties are
located in the Southeastern United States and Texas and, therefore, Parkway's
financial condition and its ability to make expected distributions to
stockholders will be linked to economic conditions in these markets as well as
the market for office space generally. To the extent that these conditions
impact the market rents for office space, they could have an adverse effect on
Parkway's financial condition and ability to make expected distributions to
stockholders.
 
     Acquisition and Development Risks.  Parkway intends to pursue acquisitions
of additional properties and, under appropriate circumstances, may pursue
development opportunities. Acquisitions entail risks that such properties will
fail to perform in accordance with expectations and that estimates of the cost
of improvements necessary to market, acquire and operate the properties will
prove inaccurate as well as general risks associated with any new real estate or
operating company acquisitions. The fact that Parkway generally must distribute
95% of its ordinary taxable income in order to maintain its qualification as a
REIT may limit Parkway's ability to rely upon lease income from its Properties
or subsequently acquired properties to finance acquisitions or new developments.
As a result, if debt or equity financing were not available on acceptable terms,
further acquisitions or development activities might be curtailed or Parkway's
financial condition and cash available for distribution to stockholders might be
adversely affected.
 
     Tenant Defaults.  A substantial part of Parkway's revenues and income is
derived from rental income from real property. Consequently, Parkway's financial
condition and ability to make expected distributions to stockholders and to use
its Properties as collateral for its borrowings would be adversely affected if a
significant number of tenants failed to meet their lease obligations. In the
event of a default by a tenant, Parkway may experience delays in enforcing its
rights as lessor and may incur substantial costs in protecting its investment.
At any time, a tenant may also seek protection under the bankruptcy laws, which
could result in the rejection and termination of such tenant's lease and thereby
adversely affect Parkway's financial condition and ability to make expected
distributions to stockholders. If a tenant rejects its lease pursuant to
applicable bankruptcy
                                       S-4
<PAGE>   5
 
laws, Parkway's claim for breach of the lease in excess of any applicable
security deposit would (absent collateral securing the claim) be treated as a
general unsecured claim. The amount of the claim would be capped at the amount
owed for unpaid pre-petition lease payments unrelated to the rejection, plus the
greater of one year's lease payment or 15% of the remaining lease payments
payable under the lease (but not to exceed the amount of three years' lease
payments).
 
     Value and Illiquidity of Real Estate.  Real estate investments are
relatively illiquid. Parkway's ability to vary its portfolio in response to
changes in economic and other conditions will therefore be limited. If Parkway
must sell an investment, there can be no assurance that it will be able to
dispose of the investment in the time period it desires or that the sales price
of the investment will recoup or exceed the amount of Parkway's cost for the
investment.
 
     Environmental Matters.  Parkway's operating costs may be affected by the
obligation to pay for the cost of complying with existing environmental laws,
ordinances and regulations, as well as the cost of complying with future
legislation. Under various federal, state and local environmental laws,
ordinances and regulations, a current or previous owner or operator of real
property may be liable for the costs of removal or remediation of hazardous or
toxic substances on, under, or in such property. Such laws often impose
liability whether or not the owner or operator knew of, or was responsible for,
the presence of such hazardous or toxic substances. In addition, the presence of
hazardous or toxic substances, or the failure to remediate such property
properly, may adversely affect the owner's ability to borrow by using such real
property as collateral. Persons who arrange for the transportation, disposal or
treatment of hazardous or toxic substances may also be liable for the costs of
removal or remediation of such substances at the disposal or treatment facility,
whether or not such facility is or ever was owned or operated by such person.
Certain environmental laws and common law principles could be used to impose
liability for releases of hazardous materials, including asbestos-containing
materials ("ACMs"), into the environment, and third parties may seek recovery
from owners or operators of real properties for personal injury associated with
exposure to released ACMs or other hazardous materials. Parkway is not aware of
any material ACM problems at its Properties. However, there can be no assurance
that ACMs do not exist at Properties owned by Parkway. If there are ACMs at the
Properties that require removal or other remediation, the cost thereof could be
substantial. This fact could have an adverse effect on the value of such
Property.
 
     Environmental laws may also impose restrictions on the manner in which a
property may be used or transferred or in which businesses may be operated, and
these restrictions may require expenditures. In connection with the ownership
and operation of its Properties, Parkway may be potentially liable for any such
costs. The cost of defending against claims of liability or remediating
contaminated property and the cost of complying with environmental laws could
materially adversely affect Parkway's results of operations and financial
condition and ability to make expected distributions to stockholders. Phase I
environmental site assessments ("ESAs") have been conducted at all but one of
the office Properties by qualified independent environmental engineers. The
purpose of Phase I ESAs is to identify potential sources of contamination for
which any of the Properties may be responsible and to assess the status of
environmental regulatory compliance. The ESAs have not revealed any
environmental liability or compliance concerns that Parkway believes would have
a material adverse effect on its business, assets, results of operations or
liquidity. With the exception of Veritas Technology Center ("Veritas"), which is
adjacent to a Texaco-branded service station, Parkway is not aware of any such
liability or concerns. Nevertheless, it is possible that these ESAs did not
reveal all environmental liabilities or compliance concerns or that material
environmental liabilities or compliance concerns exist of which Parkway is
currently unaware. Parkway has not been notified by any governmental authority,
and has no other knowledge of, any material noncompliance, liability or claim
relating to hazardous or toxic substances or other environmental substances in
connection with any of the Properties. Parkway intends to perform additional
Phase I ESAs with respect to properties acquired in the future.
 
     Environmental due diligence performed in connection with the purchase of
the Veritas property disclosed that the Texaco-branded service station located
on the neighboring property has released certain petroleum products which may
have migrated from the station to the Veritas property. The owner of the
neighboring property, Star Enterprise ("Star"), pursuant to an indemnity
agreement (the "Indemnity Agreement") dated
 
                                       S-5
<PAGE>   6
 
January 1998 between Star and Veritas Real Estate (U.S.A.), Inc. (the prior
owner of the Veritas property), has agreed to indemnify and hold harmless all
future owners of the Veritas property from all losses incurred in connection
with the presence of petroleum hydrocarbons on the Veritas property from the
station. Parkway believes that Star has sufficient financial reserves to
indemnify Parkway for any potential costs related to the clean up of the
petroleum hydrocarbons. However, if Star is unable to fully comply with its
indemnity obligation Parkway may be subject to liability and costs associated
with any clean up of the petroleum hydrocarbons.
 
     Competition.  All of the Properties owned by Parkway are located in
developed areas. There are numerous other office properties and real estate
companies within the market area of each such Property which will compete with
Parkway for tenants and acquisition and development opportunities. The number of
competitive office properties and real estate companies in such areas could have
a material effect on (i) Parkway's ability to rent space at the Properties; (ii)
the amount of rents currently charged and to be charged upon expiration of
leases; (iii) the amount of tenant improvements and other tenant concessions
required to lease the Properties; and (iv) acquisition and development
opportunities. Parkway will compete for tenants and acquisitions with other
competitors who may have greater resources than Parkway.
 
     Uninsured and Underinsured Losses.  Parkway has obtained or has caused its
tenants to obtain commercial general liability, fire and extended coverage
insurance with respect to its Properties of the types and in the amounts which
Parkway believes is of the type and amount customarily obtained for or by an
owner of office properties. Parkway plans to obtain similar coverage for any
properties acquired in the future. However, there are certain types of losses,
generally of a catastrophic nature, such as earthquakes and floods, that may be
uninsurable or not economically insurable. The Board of Directors and management
of Parkway will use their discretion in determining amounts, coverage limits and
deductibility provisions of insurance, with a view to maintaining appropriate
insurance coverage on the investments of Parkway, as the case may be, at a
reasonable cost and on suitable terms. This may result in insurance coverage
that, in the event of a substantial loss, would not be sufficient to pay the
full current market value or current replacement cost of the lost investment of
Parkway. Inflation, changes in building codes and ordinances, environmental
considerations, and other factors also might make it not feasible to use
insurance proceeds to replace the property after such property has been damaged
or destroyed. Under such circumstances, the insurance proceeds received by
Parkway might not be adequate to restore its economic position with respect to
such property.
 
     Property Taxes.  The Properties are subject to real property taxes. The
real property taxes on the Properties may increase or decrease as property tax
rates change and as the value of the Properties are assessed or reassessed by
taxing authorities. If property taxes increase, Parkway's ability to make
distributions to its stockholders could be adversely affected.
 
     Cost of Compliance with Americans with Disabilities Act.  Under the
Americans with Disabilities Act of 1990, as amended (the "ADA"), all public
accommodations are required to meet certain federal requirements related to
access and use by disabled persons. Compliance with the public accommodations
provision of the ADA could require the removal of access barriers, and
noncompliance could result in the imposition of fines or awards of damages.
Additional legislation may impose further burdens or restrictions on owners with
respect to access by disabled persons. In many instances, the applicability and
requirements of the ADA are not clear. Accordingly, the cost of compliance with
the ADA or such legislation is not currently ascertainable, and, while such
costs are not expected to have a material adverse effect on Parkway's financial
condition, such costs could be substantial. Parkway has not undertaken ADA
studies of all of its Properties and, as to those Properties with respect to
which Parkway has not undertaken ADA studies, possible costs of compliance could
arise.
 
CONFLICTS OF INTEREST
 
     Leland R. Speed serves as Chairman of both Parkway and EastGroup
Properties, Inc., a REIT with a focus on industrial properties in sunbelt states
and California. As both companies carry out their strategic plans, management of
each company has stated its intention not to transfer properties between the two
entities, and each company intends to pursue its distinct corporate plan. There
can be no assurance that conflicts of interest will not arise between the two
companies in the future.

<PAGE>   7
 
LIMITS ON CHANGES IN CONTROL
 
     Certain provisions contained in Parkway's Articles of Incorporation, as
amended (the "Charter"), and Bylaws, as amended, certain of Parkway's agreements
and certain provisions of Maryland law may have the effect of discouraging a
third party from making an acquisition proposal for Parkway and may thereby
inhibit a change in control of Parkway. These include provisions of the Maryland
General Corporation Law relating to certain "business combinations" and "control
share" acquisitions involving Maryland corporations, Parkway's Rights Agreement
(described under "Description of Common Stock" in the accompanying Prospectus),
Parkway's Change in Control Agreements with certain executive officers, and
certain provisions of the Charter intended to protect Parkway's status as a REIT
described below under " -- Possible Adverse Consequence of Limits on Ownership
of Common Stock." Such provisions may (i) deter tender offers for Common Stock,
which may be attractive to the stockholders; or (ii) deter purchases of large
blocks of Common Stock, thereby limiting the opportunity for stockholders to
receive a premium for their Common Stock over then-prevailing market prices.
 
POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF COMMON STOCK
 
     Certain provisions of the Charter provide that if a transfer of stock of
Parkway or a change in the capital structure of Parkway would result in (i) any
person (as defined in the Charter) directly or indirectly acquiring beneficial
ownership of more than 9.8% (in value or in number, whichever is more
restrictive) of the outstanding capital stock of Parkway excluding Excess Stock
(as defined below); (ii) the outstanding shares of Parkway being constructively
or beneficially owned by fewer than 100 persons; (iii) Parkway being "closely
held" within the meaning of Section 856 of the Internal Revenue Code of 1986, as
amended (the "Code"), then: (A) any proposed transfer will be void ab initio and
will not be recognized by Parkway; (B) Parkway will have the right to redeem the
shares proposed to be transferred; and (C) the shares proposed to be transferred
will be automatically converted into and exchanged for shares of a separate
class of stock, the excess stock, par value $0.001 per share, of Parkway
("Excess Stock"), having no dividend or voting rights. Holders of Excess Stock
do have certain rights in the event of any liquidation, dissolution or winding
up of the Company. The Charter further provides that the Excess Stock will be
held by Parkway as trustee for the person or persons to whom the shares are
ultimately transferred, until such time as the shares are retransferred to a
person or persons in whose hands the shares would not be Excess Stock and
certain price-related restrictions are satisfied. These provisions are designed
to enable Parkway to meet the share ownership requirements applicable to REITs
under the Code, but may also have the effect of discouraging tender offers or
purchases of large blocks of stock, thereby limiting the opportunity for
stockholders to receive a premium for their Common Stock over then-prevailing
market prices.
 
POSSIBLE ADVERSE IMPACT OF MARKET CONDITIONS ON MARKET PRICE
 
     The market value of the Common Stock could be substantially affected by
general market conditions, including changes in interest rates, government
regulatory action and changes in tax laws. An increase in market interest rates
may lead purchasers of the Common Stock to demand a higher annual dividend yield
on the Common Stock, which could adversely affect the market price of the Common
Stock. Moreover, numerous other factors, such as government regulatory action
and changes in tax laws, could have a significant impact on the future market
price of the Common Stock or other securities.
 
REIT ELECTION TAX RISKS
 
     Parkway intends to elect and qualify to be taxed as a REIT under the Code,
commencing with its taxable year beginning January 1, 1997. Although management
of Parkway believes that Parkway has been organized and operated and will
continue to operate in such a manner, no assurance can be given that Parkway has
operated or will be able to continue to operate in a manner so as to qualify or
remain so qualified. Qualification as a REIT depends upon Parkway meeting and
continuing to meet the various highly technical and complex Code provisions and
REIT qualification rules, which include (i) maintaining ownership of specified
minimum levels of real estate related assets; (ii) generating specified minimum
levels of real estate related income; (iii) maintaining certain diversity of
ownership requirements with respect to Parkway shares; (iv) having no
                                       S-7
<PAGE>   8
 
positive earnings and profits account from years in which Parkway was not
qualified as a REIT; and (v) distributing at least 95% of all real estate
investment taxable income on an annual basis. There are only limited judicial
and administrative interpretations of such rules. Furthermore, the determination
of various factual matters and circumstances not entirely within Parkway's
control may affect Parkway's ability to qualify as a REIT.
 
     If Parkway fails to qualify as a REIT for any taxable year, Parkway will be
subject to federal income tax (including any applicable alternative minimum tax)
on its taxable income at regular corporate rates. In addition, unless entitled
to relief under certain statutory provisions, Parkway will be disqualified from
treatment as a REIT for the four taxable years following the year during which
qualification is lost. This treatment would reduce the net earnings of Parkway
available for investment or distribution to stockholders because of the
additional tax liability to Parkway for the year or years involved. In addition,
distributions would no longer be required to be made. To the extent that
distributions to stockholders had been made in anticipation of Parkway's
qualifying as a REIT, Parkway might be required to borrow funds or to liquidate
certain of its investments to pay the applicable tax. See "Federal Income Tax
Considerations -- Taxation of the Company" in the Prospectus attached hereto.
 
FORWARD-LOOKING STATEMENTS
 
     The Private Securities Litigation Reform Act of 1995 provides a "safe
harbor" for forward-looking statements. This Prospectus Supplement, the
accompanying Prospectus and other materials filed or to be filed by the Company
with the Securities and Exchange Commission under the Exchange Act and
incorporated by reference in the accompanying Prospectus contain or will contain
forward-looking statements within the meaning of Section 27A of the Securities
Act and Section 21E of the Exchange Act. Such statements include information
relating to acquisitions and other business development activities, future
capital expenditures, financing sources and availability and the effects of
regulations (including environmental regulation) and competition. Such
forward-looking information involves important risks and uncertainties that
could significantly affect anticipated results in the future and, accordingly,
such results may differ from those expressed in any forward-looking statements
contained in this Prospectus Supplement or the accompanying Prospectus or
incorporated by reference in such Prospectus. These risks and uncertainties
include, but are not limited to, uncertainties affecting real estate businesses
generally (such as entry into new leases, renewals of leases and dependence on
tenants' business operations), risks relating to acquisition and development
activities, possible environmental liabilities, risks relating to leverage, debt
service and obligations with respect to the payment of dividends (including
availability of financing terms acceptable to the Company and sensitivity of the
Company's operations to fluctuations in interest rates), the potential for the
need to use borrowings to make distributions necessary for the Company to
qualify as a REIT or to fund the payment of dividends, dependence on the primary
markets in which the Properties are located, the existence of complex
regulations relating to the Company's status as a REIT and the adverse
consequences of the failure of the Company to qualify as a REIT and the
potential adverse impact of market interest rates on the market price for the
Company's securities.
 
                              RECENT DEVELOPMENTS
 
     Brookdale Acquisition.  In February 1998, the Company purchased a portfolio
of 13 office buildings (the "Brookdale Portfolio") with an aggregate of
approximately 1.5 million net rentable square feet for a total investment of
approximately $165 million, or $113 per net rentable square foot. The properties
included in this portfolio are located in Fort Lauderdale, Florida; Greenville,
South Carolina; Knoxville, Tennessee; Dallas and Houston, Texas; and Northern
Virginia and Virginia Beach, Virginia.
 
     Financing Activities.  In connection with the purchase of the Brookdale
Portfolio, Parkway increased its Acquisition Facility from $55 million to $85
million and reduced the interest rate on the Acquisition Facility from LIBOR
plus 1.75% to LIBOR plus 1.40% (7.032% as of March 2, 1998). The Acquisition
Facility matures on June 30, 1998. Also in connection with the purchase of the
Brookdale Portfolio, Parkway obtained the February Facility in February 1998
with a maximum principal amount of $75 million which is
 
                                       S-8
<PAGE>   9
 
accompanied by negative pledges with respect to the 13 properties in the
Brookdale Portfolio. The February Facility has an interest rate of 7.025% until
April 24, 1998 and thereafter will have an interest rate of LIBOR plus 1.40% and
matures on August 25, 1998. Parkway also has the Working Capital Facility with a
maximum principal amount of $15 million. In connection with the restructuring of
the Acquisition Facility, the interest rate on the Working Capital Facility was
also reduced from LIBOR plus 1.75% to LIBOR plus 1.40%. The Working Capital
Facility matures on June 30, 1998. As of March 5, 1998, on an as adjusted basis
assuming completion of the Offering and the application of the net proceeds
therefrom, there was approximately $58.1 million outstanding under the
Acquisition Facility, approximately $75.0 million outstanding under the February
Facility and approximately $3.8 million outstanding under the Working Capital
Facility.
 
     UPREIT Structure.  In January 1998, Parkway completed its reorganization
into an umbrella partnership REIT ("UPREIT") structure under which all of
Parkway's office building real estate assets are owned by an operating
partnership, Parkway Properties LP, a Delaware limited partnership (the
"Operating Partnership"). The Company anticipates that the UPREIT structure will
enable it to pursue new investment opportunities by having the ability to offer
units in the Operating Partnership to property owners in exchange for office
properties in transactions that may have preferable tax characteristics.
Presently, all interests in the Operating Partnership are owned by wholly-owned
subsidiaries of Parkway.
 
     1997 Year-End Results.  Parkway reported total revenue of $48.1 million for
the year ended December 31, 1997, compared to $24.1 million for the year ended
December 31, 1996. The Company reported net income and funds from operations
("FFO") for the year ended December 31, 1997, of $14.5 million and $17.6
million, respectively, compared to $14.4 million and $6.4 million, respectively,
for the year ended December 31, 1996. Parkway defines FFO, consistent with
NAREIT's definition, as net income (loss) (computed in accordance with generally
accepted accounting principles ("GAAP")), excluding gains (or losses) from debt
restructuring and sales of property, plus real estate related depreciation and
amortization and after adjustments for unconsolidated partnerships and joint
ventures. The Company believes FFO is helpful to investors as a measure of the
performance of an equity REIT because, along with cash flows from operating
activities, financing activities and investing activities, it provides investors
with an understanding of the ability of the Company to incur and service debt
and make capital expenditures. The Company computes FFO in accordance with
standards established by Parkway, which may differ from the methodology for
calculating FFO utilized by other equity REITs, and, accordingly, may not be
comparable to such other REITs. Further, FFO does not represent amounts
available for management's discretionary use because of needed capital
replacement or expansion, debt service obligations, or other commitments and
uncertainties. FFO should not be considered as an alternative to net income
(determined in accordance with GAAP) as an indication of the Company's financial
performance or to cash flows from operating activities (determined in accordance
with GAAP) as a measure of the Company's liquidity, nor is it indicative of
funds available to fund the Company's cash needs, including its ability to make
distributions.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     For a discussion of certain material federal income tax consequences of the
current taxation of Parkway, the current impact on Parkway of its election to be
treated as a REIT, and the current taxation of prospective stockholders of
Parkway, see "Federal Income Tax Considerations" in the accompanying Prospectus.
 
     Prospective purchasers should be aware that on August 5, 1997, President
Clinton signed into law the Taxpayer Relief Act of 1997 (the "Taxpayer Relief
Act"). The Taxpayer Relief Act made certain changes to the Code, including
changes with respect to the treatment of REITs and stockholders of REITs. These
changes generally became effective with respect to Parkway and stockholders of
Parkway on January 1, 1998. In addition, the Taxpayer Relief Act reduced the
maximum tax on net capital gains from the sale of assets held for more than 18
months by individuals, trusts and estates.
 
     In an effort to simplify the taxation of REITs, the Taxpayer Relief Act
changed certain requirements for a corporation electing to be taxed as a REIT
and the taxation of REIT stockholders. First, Parkway is required
 
                                       S-9
<PAGE>   10
 
to maintain certain records and request on an annual basis certain information
from its stockholders concerning the ownership of its outstanding shares in
accordance with applicable Treasury Regulations. Under prior law, this
requirement was a condition to being taxed as a REIT. For taxable years
beginning after December 31, 1997, the Taxpayer Relief Act provides that the
record maintenance and ownership information request requirements are no longer
conditions to taxation as a REIT. Instead, a monetary penalty will be imposed
for failure to comply with such requirements. Second, the Taxpayer Relief Act
repealed the 30% gross income test for taxable years beginning after December
31, 1997. Third, the Taxpayer Relief Act changed the definition of "rents from
real property." Under prior law, rents received with respect to a property
generally did not qualify as "rents from real property" if Parkway directly
provided services to tenants other than those that were "usually or customarily
rendered" in connection with the rental of space for occupancy only and which
were not otherwise considered "rendered to the occupant." For taxable years
beginning after December 31, 1997, rental income received by Parkway will not
cease to qualify as "rents from real property" merely because Parkway performs
non-customary services for a tenant if the amount that Parkway receives as a
result of performing such services does not exceed one percent of all amounts
received directly or indirectly by Parkway with respect to such property. In
applying this limitation, the amount that Parkway is treated as having received
for performing such services will not be less than 150% of the direct cost to
Parkway of providing those services. Fourth, the Taxpayer Relief Act simplified
the requirements for qualification of a corporation as a "qualified REIT
subsidiary." Fifth, for taxable years beginning after December 31, 1997, the
Taxpayer Relief Act allows Parkway to elect to retain and pay tax on net
long-term capital gains and require its stockholders to include their
proportionate share of such undistributed net capital gains in their income. If
Parkway makes such election, stockholders would receive a tax credit
attributable to their share of the capital gains tax paid by Parkway, and would
receive an increase in the basis of their shares in Parkway in an amount equal
to the stockholder's share of the undistributed net long-term capital gain
reduced by the amount of the credit. Further, any undistributed net long-term
capital gains that are included in the income of Parkway stockholders pursuant
to this rule, will be treated as distributed for purposes of the 4% excise tax
which Parkway must pay should Parkway fail to distribute at least 95% of
Parkway's capital gain for such taxable year.
 
     The Taxpayer Relief Act also reduced the top tax rate for individuals,
estates and trusts on certain long-term capital gains. Generally, long-term
capital gains on property held for more than 18 months will not be taxed at a
rate greater than 20% and the maximum rate is reduced to 18% for assets acquired
after December 31, 2000 and held for more than five years. For taxpayers subject
to the 15% regular tax bracket, long-term capital gains on property held for
more than 18 months will not be taxed at a rate greater than 10%, and, effective
for taxable years beginning after December 31, 2000, the rate is reduced to 8%
for assets held more than five years. Long-term capital gain from the sale or
exchange of certain depreciable real property held for more than 18 months which
would be treated as ordinary income if the real property was depreciable
personal property is subject to a maximum tax rate of 25% rather than 20%.
Long-term capital gain (other than certain depreciation recapture taxable as
ordinary income) allocated to a stockholder by Parkway will be subject to the
25% rate to the extent that the gain does not exceed depreciation on real
property sold by Parkway. The maximum rate of capital gains tax for capital
assets held for more than one year but not more than 18 months remains at 28%.
The taxation of capital gains by corporations was not changed by the Taxpayer
Relief Act.
 
     In addition, Internal Revenue Notice 97-64 provides temporary guidance with
respect to the taxation of distributions by Parkway designated as capital gain
dividends. Pursuant to Internal Revenue Notice 97-64, forthcoming Temporary
Regulations will provide that capital gains allocated to a stockholder by a REIT
may be designated as a 20% rate gain distribution, an unrecaptured Section 1250
gain distribution (subject to the 25% rate), or a 28% rate gain distribution. In
determining the amounts which may be designated as each class of capital gains
dividends, a REIT must calculate its net capital gains as if it were an
individual subject to a marginal tax rate of 28%. Unless specifically designated
otherwise by Parkway, a distribution designated as a capital gain distribution
is presumed to be a 28% rate gain distribution. If Parkway elects to retain any
net long-term capital gain, as discussed above, the undistributed long-term
capital gains are considered to be designated as capital gain dividends for
purposes of Internal Revenue Notice 97-64.

     Potential Legislative Action Regarding REITs.  On February 2, 1998, the
Clinton Administration released a summary of its proposed budget plan which
contained several proposals affecting REITs. One such proposal, if enacted in
its present form, would prohibit a REIT from holding securities representing
more than 10% of the value of all classes of stock of a corporation, other than
a qualified REIT subsidiary or another REIT. If enacted in its present form, the
proposal may limit Parkway's ability to perform certain third party management
or other non-real estate related activities in the future. No prediction can be
made as to whether such proposal or any other proposal affecting REITs will be
enacted into legislation and the impact of any such legislation on Parkway.

    the exercise of outstanding options granted pursuant to Parkway's option
    plans.
 
                                USE OF PROCEEDS
 
     The net proceeds to Parkway from the sale of the Shares pursuant to this
Prospectus Supplement, after deducting total estimated expenses of $50,000 and
$550,986 to be paid to PaineWebber for its services as a finder in connection
with the Offering, are estimated to be approximately $26.9 million. Parkway
intends to use all of the net proceeds from the Offering to repay outstanding
indebtedness under the Acquisition Facility. The Acquisition Facility bears
interest at LIBOR plus 1.40% which translated into a 7.032% interest rate as of
March 2, 1998. The Acquisition Facility matures on June 30, 1998. After the
application of the net proceeds from the Offering, the outstanding balance on
the Acquisition Facility will be approximately $58.1 million.
 
     Pending application of the net proceeds, Parkway will invest such proceeds
in interest-bearing accounts and short-term, interest-bearing securities, which
is consistent with Parkway's intention to qualify for taxation as a REIT. Such
investments may include certificates of deposit, interest-bearing bank deposits
and money market investments.
 
                              PLAN OF DISTRIBUTION
 
     The Company will sell the Shares offered hereby directly to one or more
institutional investors. In connection with the sale of the Shares offered
hereby, PaineWebber will be paid a fee in the amount of approximately $550,986
in consideration of its services as a finder in connection with the sale. Such
fee represents, on a weighted average basis, approximately 2% of the gross
proceeds of the sale of the Shares in the Offering.
 
     In addition, the Company has agreed to indemnify PaineWebber against
certain liabilities, including liabilities under the Securities Act, or to
contribute to payments PaineWebber may be required to make in respect thereof.
 
     PaineWebber and/or the purchasers in the Offering may be deemed to be
underwriters within the meaning of the Securities Act in connection with the
placement of the Shares.
 
     The Common Stock is traded on the NYSE under the symbol "PKY."

     In the ordinary course of business, PaineWebber and/or its affiliates have
engaged and may in the future engage in financial advisory, investment banking
and other transactions with Parkway for which customary compensation has been,
and will be, received.
 
                                 LEGAL MATTERS
 
     Certain legal matters, including the legality of the Common Stock, will be
passed upon for Parkway by Jaeckle Fleischmann & Mugel, LLP, Buffalo, New York
and for PaineWebber by Rogers & Wells LLP, New York, New York. As to matters of
Maryland law contained in this opinion, Jaeckle Fleischmann & Mugel, LLP and
Rogers & Wells LLP will rely upon the opinion of Piper & Marbury L.L.P.,
Baltimore, Maryland.

                                  THE COMPANY
 
     Parkway is a self-managed real estate investment company operating as a
real estate investment trust ("REIT"), specializing primarily in the ownership,
management and leasing of office properties in the Southeastern United States
(particularly the states of Mississippi, North Carolina, Georgia and Virginia)
and Texas. At December 31, 1996, Parkway owned or had an interest in 17 office
buildings in eight states with an aggregate of approximately 1.9 million square
feet of leasable space.
 
     Parkway was incorporated under the laws of the State of Maryland on May 17,
1996. Formed as a wholly-owned subsidiary of The Parkway Company, a Texas
corporation, Parkway merged with The Parkway Company on August 2, 1996 (the
"Merger") pursuant to the Agreement and Plan of Merger dated July 17, 1996 by
and between Parkway and The Parkway Company. The Parkway Company and its
predecessors have been engaged in the real estate business since 1971. As a
result of the Merger, Parkway succeeded to the business and operations of The
Parkway Company. Additionally, on August 22, 1996 shares of common stock, par
value $0.001 per share, of Parkway (the "Common Shares") became listed on the
New York Stock Exchange, Inc. ("NYSE") under the symbol "PKY." Prior to this
date, the Common Shares had been quoted on the NASDAQ National Market under the
symbol "PKWY."
 
     Through its wholly-owned subsidiary, Parkway Realty Services, Inc.
("Parkway Realty"), Parkway is also involved in the management of commercial
properties for which it receives management fees. Parkway Realty currently
manages and leases a portfolio of approximately 1.4 million square feet of
office space. Parkway Realty also performs brokerage services to third parties
on a commission basis. Parkway Realty manages Parkway's office buildings in
Jackson, Mississippi.
 
     Parkway's offices are located at 300 One Jackson Place, 188 East Capitol
Street, Jackson, Mississippi 39201-2195. Its telephone number is (601) 948-4091.
 
                       RATIO OF EARNINGS TO FIXED CHARGES
 
     Parkway's ratio of earnings to fixed charges for the three months ended
September 30, 1996 was 1.9, for the three months ended June 30, 1996 was 1.9,
for the three months ended March 31, 1996 was 2.1, for the year ended December
31, 1995 was 1.4, for the six months ended December 31, 1994 was 1.4, for the
year ended June 30, 1994 was 1.4, for the year ended June 30, 1993 was 1.1 and
for the year ended June 30, 1992 was 0.61. There were Preferred Shares
outstanding only for a portion of the three months ended September 30, 1996.
Accordingly, the ratio of earnings to fixed charges and Preferred Shares
dividends is identical to the ratio of earnings to fixed charges for all periods
other than that ending September 30, 1996. For the three months ended September
30, 1996, the ratio of earnings to combined fixed charges and Preferred Shares
dividends was 1.8.
 
     For purposes of computing these ratios, earnings have been calculated by
adding fixed charges, excluding capitalized interest, to pre-tax income from
continuing operations (net income or loss). Fixed charges consist of interest
costs, whether expensed or capitalized, the interest component of rental expense
and amortization of debt issuance costs.
 
                                USE OF PROCEEDS
 
     Unless otherwise described in the applicable Prospectus Supplement, Parkway
intends to use the net proceeds from the offering for general corporate purposes
including, without limitation, the acquisition of real estate properties,
whether by acquisition of properties directly or through potential business
combination transactions, development of new real estate properties, the
repayment of debt and to fund working capital requirements.
 
                         DESCRIPTION OF DEBT SECURITIES
 
     The unsecured debt securities ("Debt Securities") will be issued in one or
more series under an Indenture (the "Indenture"), which may be supplemented by
supplemental indentures (each, an "Indenture Supplement"), between Parkway and a
trustee (the "Trustee") to be chosen by Parkway and qualified to act as Trustee
under the Trust Indenture Act of 1939, as amended (the "TIA"). A copy of the
form of the
 
                                        4
<PAGE>   17
 
Indenture has been filed as an exhibit to the Registration Statement of which
this Prospectus is a part and will be available for inspection at the corporate
trust office of the Trustee or as described above under "Available Information."
The Indenture is subject to, and governed by, the TIA. The statements made
hereunder relating to the Indenture and the Debt Securities to be issued
thereunder are summaries of certain provisions thereof and do not purport to be
complete and are subject to, and are qualified in their entirety by reference
to, all provisions of the Indenture and such Debt Securities. All section
references appearing herein are to sections of the Indenture, and capitalized
terms used but not defined herein shall have the respective meanings set forth
in the Indenture.
 
GENERAL
 
     The Debt Securities will be direct, unsecured obligations of Parkway and
will rank equally with all other unsecured and unsubordinated indebtedness of
Parkway. At December 31, 1996, the total outstanding debt of Parkway was
approximately $62,828,000, none of which was unsubordinated indebtedness and
none of which was secured debt. Except as may be set forth in an applicable
Prospectus Supplement, the Debt Securities may be issued without limit as to
aggregate principal amount, in one or more series, in each case as established
from time to time in or pursuant to authority granted by a resolution of the
Board of Directors of Parkway or as established in one or more Indenture
Supplements. All Debt Securities of one series need not be issued at the same
time and, unless otherwise provided, a series may be reopened, without the
consent of the holders of the Debt Securities of such series, for issuance of
additional Debt Securities of such series.
 
     The Indenture provides that there may be more than one Trustee thereunder,
each with respect to one or more series of Debt Securities. Any Trustee under
the Indenture may resign or be removed with respect to one or more series of
Debt Securities, and a successor Trustee may be appointed to act with respect to
such series. In the event that two or more persons are acting as Trustee with
respect to different series of Debt Securities, each such Trustee shall be a
trustee of a trust under the Indenture separate and apart from the trust
administered by any other Trustee, and, except as otherwise indicated herein,
any action described herein to be taken by a Trustee may be taken by each such
Trustee with respect to, and only with respect to, the one or more series of
Debt Securities for which it is Trustee under the Indenture.
 
     Reference is made to the Prospectus Supplement relating to the series of
Debt Securities offered thereby for the specific terms thereof, including:
 
          (i) the title of such Debt Securities;
 
          (ii) the aggregate principal amount of such Debt Securities and any
     limit on such aggregate principal amount;
 
          (iii) the percentage of the principal amount at which such Debt
     Securities will be issued and, if other than the principal amount thereof,
     the portion of the principal amount thereof payable upon declaration of
     acceleration of the maturity thereof;
 
          (iv) the date or dates, or the method for determining such date or
     dates, on which the principal of such Debt Securities will be payable;
 
          (v) the rate or rates (which may be fixed or variable), or the method
     by which such rate or rates shall be determined, at which such Debt
     Securities will bear interest, if any;
 
          (vi) the date or dates, or the method for determining such date or
     dates, from which any interest will accrue, the dates on which any such
     interest will be payable, the record dates for such interest payment dates,
     or the method by which any such date shall be determined, the person to
     whom such interest shall be payable, and the basis upon which interest
     shall be calculated if other than that of a 360-day year of twelve 30-day
     months;
 
          (vii) the place or places where the principal of (and premium, if any)
     and interest, if any, on such Debt Securities will be payable, such Debt
     Securities may be surrendered for registration of transfer or exchange and
     notices or demands to or upon Parkway in respect of such Debt Securities
     and the Indenture may be served;
                                        5
<PAGE>   18
 
          (viii) the period or periods within which, the price or prices at
     which and the terms and conditions upon which such Debt Securities may be
     redeemed, in whole or in part, at the option of Parkway, if Parkway is to
     have such an option;
 
          (ix) the obligation, if any, of Parkway to redeem, repay or purchase
     such Debt Securities pursuant to any sinking fund or analogous provision or
     at the option of a holder thereof, and the period or periods within which,
     the price or prices at which and the terms and conditions upon which such
     Debt Securities will be redeemed, repaid or purchased, in whole or in part,
     pursuant to such obligation;
 
          (x) if other than U.S. dollars, the currency or currencies in which
     such Debt Securities are denominated and payable, which may be a foreign
     currency or units of two or more foreign currencies or a composite currency
     or currencies, and the terms and conditions relating thereto;
 
          (xi) whether the amount of payments of principal of (and premium, if
     any) or interest, if any, on such Debt Securities may be determined with
     reference to an index, formula or other method (which index, formula or
     method may be, but need not be, based on a currency, currencies, currency
     unit or units of composite currency or currencies) and the manner in which
     such amounts shall be determined;
 
          (xii) the events of default or covenants of such Debt Securities, to
     the extent different from or in addition to those described herein;
 
          (xiii) whether such Debt Securities will be issued in certificated
     and/or book-entry form;
 
          (xiv) whether such Debt Securities will be in registered or bearer
     form and, if in registered form, the denominations thereof if other than
     $1,000 and any integral multiple thereof and, if in bearer form, the
     denominations thereof if other than $5,000 and terms and conditions
     relating thereto;
 
          (xv) the applicability, if any, of the defeasance and covenant
     defeasance provisions described herein, or any modification thereof;
 
          (xvi) if such Debt Securities are to be issued upon the exercise of
     debt warrants, the time, manner and place of such Debt Securities to be
     authenticated and delivered;
 
          (xvii) whether and under what circumstances Parkway will pay
     additional amounts on such Debt Securities in respect of any tax,
     assessment or governmental charge and, if so, whether Parkway will have the
     option to redeem such Debt Securities in lieu of making such payment;
 
          (xviii) with respect to any Debt Securities that provide for optional
     redemption or prepayment upon the occurrence of certain events (such as a
     change of control of Parkway), (a) the possible effects of such provisions
     on the market price of Parkway's securities or in deterring certain
     mergers, tender offers or other takeover attempts, and the intention of
     Parkway to comply with the requirements of Rule 14e-1 under the Securities
     Exchange Act of 1934, as amended (the "Exchange Act"), and any other
     applicable securities laws in connection with such provisions; (b) whether
     the occurrence of the specified events may give rise to cross-defaults on
     other indebtedness such that payment on such Debt Securities may be
     effectively subordinated; and (c) the existence of any limitations on
     Parkway's financial or legal ability to repurchase such Debt Securities
     upon the occurrence of such an event (including, if true, the lack of
     assurance that such a repurchase can be effected) and the impact, if any,
     under the Indenture of such a failure, including whether and under what
     circumstances such a failure may constitute an Event of Default; and
 
          (xix) any other terms of such Debt Securities not inconsistent with
     the terms of the Indenture.
 
     The Debt Securities may provide for less than the entire principal amount
thereof to be payable upon declaration of acceleration of the maturity thereof
("Original Issue Discount Securities"). If material or applicable, special U.S.
federal income tax, accounting and other considerations applicable to Original
Issue Discount Securities will be described in the applicable Prospectus
Supplement.
 
     Except as described under " -- Merger, Consolidation or Sale" below or as
may be set forth in any Prospectus Supplement, the Indenture does not contain
any other provisions that would limit the ability of
 
                                        6
<PAGE>   19
 
Parkway to incur indebtedness or that would afford holders of the Debt
Securities protection in the event of (i) a highly leveraged or similar
transaction involving Parkway or any affiliate of Parkway; (ii) a change of
control; or (iii) a reorganization, restructuring, merger or similar transaction
involving Parkway that may adversely affect the holders of the Debt Securities.
In addition, subject to the limitations set forth under " -- Merger,
Consolidation or Sale" below, Parkway may, in the future, enter into certain
transactions, such as the sale of all or substantially all of its assets or the
merger or consolidation of Parkway, that would increase the amount of Parkway's
indebtedness or substantially reduce or eliminate Parkway's assets, which may
have an adverse effect on Parkway's ability to service its indebtedness,
including the Debt Securities. In addition, restrictions on ownership and
transfers of Common Shares and Preferred Shares are designed to preserve its
status as a REIT and, therefore, may act to prevent or hinder a change of
control. See "Description of Common Shares -- Restrictions on Transfer" and
"Description of Preferred Shares -- Restrictions on Ownership." Reference is
made to the applicable Prospectus Supplement for information with respect to any
deletions from, modifications of or additions to the events of default or
covenants that are described below, including any addition of a covenant or
other provision providing event risk or similar protection.
 
     Reference is made to " -- Certain Covenants" below and to the description
of any additional covenants with respect to a series of Debt Securities in the
applicable Prospectus Supplement. Except as otherwise described in the
applicable Prospectus Supplement, compliance with such covenants generally may
not be waived with respect to a series of Debt Securities by the Board of
Directors of Parkway or by the Trustee unless the Holders of at least a majority
in principal amount of all outstanding Debt Securities of such series consent to
such waiver, except to the extent that the defeasance and covenant defeasance
provisions of the Indenture described under " -- Discharge, Defeasance and
Covenant Defeasance" below apply to such series of Debt Securities. See
" -- Modification of the Indenture."
 
     Debt Securities may be denominated and payable in a foreign currency or
units of two or more foreign currencies or a composite currency or currencies.
As more fully described in the applicable Prospectus Supplement, awards or
judgments by a court in the United States in connection with a claim with
respect to any Debt Securities denominated other than in United States dollars
(or a judgment denominated other than in United States dollars in respect of
such claims) may be converted into United States dollars at a rate of exchange
prevailing on a date determined pursuant to applicable law.
 
DENOMINATIONS, INTEREST, REGISTRATION AND TRANSFER
 
     Unless otherwise described in the applicable Prospectus Supplement, the
Debt Securities of any series which are registered securities, other than
registered securities issued in global form (which may be of any denomination),
shall be issuable in denominations of $1,000 and any integral multiple thereof
and the Debt Securities which are bearer securities, other than bearer
securities issued in global form (which may be of any denomination), shall be
issuable in denominations of $5,000.
 
     Unless otherwise described in the applicable Prospectus Supplement, the
principal of (and premium, if any) and interest on any series of Debt Securities
will be payable at the corporate trust office of the Trustee, provided that, at
the option of Parkway, payment of interest may be made by check mailed to the
address of the Person entitled thereto as it appears in the applicable Security
Register or by wire transfer of funds to such Person at an account maintained
within the United States.
 
     Unless otherwise described in the applicable Prospectus Supplement, any
interest not punctually paid or duly provided for on any Interest Payment Date
with respect to a Debt Security ("Defaulted Interest") will forthwith cease to
be payable to the Holder on the applicable Regular Record Date and may either be
paid to the Person in whose name such Debt Security is registered at the close
of business on a special record date (the "Special Record Date") for the payment
of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to the Holder of such Debt Security not less than 10 days prior to such
Special Record Date, or may be paid at any time in any other lawful manner, all
as more completely described in the Indenture.
 
     Subject to certain limitations imposed upon Debt Securities issued in book
entry form, the Debt Securities of any series will be exchangeable for other
Debt Securities of the same series and of a like
                                        7
<PAGE>   20
 
aggregate principal amount and tenor of different authorized denominations upon
surrender of such Debt Securities at the corporate trust office of the Trustee
referred to above. In addition, subject to certain limitations imposed upon Debt
Securities issued in book entry form, the Debt Securities of any series may be
surrendered for registration of transfer thereof at the corporate trust office
of the Trustee referred to above. Every Debt Security surrendered for
registration of transfer or exchange shall be duly endorsed or accompanied by a
written instrument of transfer. No service charge will be made for any
registration of transfer or exchange of any Debt Securities, but the Trustee or
Parkway may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. If the applicable
Prospectus Supplement refers to any transfer agent (in addition to the Trustee)
initially designated by Parkway with respect to any series of Debt Securities,
Parkway may at any time rescind the designation of any such transfer agent or
approve a change in the location through which any such transfer agent acts,
except that Parkway will be required to maintain a transfer agent in each place
of payment for such series. Parkway may at any time designate additional
transfer agents with respect to any series of Debt Securities.
 
     Neither Parkway nor the Trustee shall be required (i) to issue, register
the transfer of or exchange any Debt Security if such Debt Security may be among
those selected for redemption during a period beginning at the opening of
business 15 days before selection of the Debt Securities to be redeemed and
ending at the close of business on (a) if such Debt Securities are issuable only
as Registered Securities, the day of the mailing of the relevant notice of
redemption and (b) if such Debt Securities are issuable as Bearer Securities,
the day of the first publication of the relevant notice of redemption or, if
such Debt Securities are also issuable as Registered Securities and there is no
publication, the mailing of the relevant notice of redemption; or (ii) to
register the transfer of or exchange any Registered Security so selected for
redemption in whole or in part, except, in the case of any Registered Security
to be redeemed in part, the portion thereof not to be redeemed; or (iii) to
exchange any Bearer Security so selected for redemption except that such a
Bearer Security may be exchanged for a Registered Security of that series and
like tenor, provided that such Registered Security shall be simultaneously
surrendered for redemption; or (iv) to issue, register the transfer of or
exchange any Debt Security which has been surrendered for repayment at the
option of the Holder, except the portion, if any, of such Debt Security not to
be so repaid.
 
MERGER, CONSOLIDATION OR SALE
 
     Parkway may consolidate with, or sell, lease or convey all or substantially
all of its assets to, or merge with or into, any other entity, provided that (i)
Parkway shall be the continuing entity or the successor entity (if other than
Parkway) formed by or resulting from any such consolidation or merger or which
shall have received the transfer of such assets shall expressly assume payment
of the principal of (and premium, if any) and interest on all the Debt
Securities and the due and punctual performance and observance of all of the
covenants and conditions contained in the Indenture; (ii) immediately after
giving effect to such transaction and treating any indebtedness which becomes an
obligation of Parkway or any Subsidiary as a result thereof as having been
incurred by Parkway or such Subsidiary at the time of such transaction, no Event
of Default under the Indenture, and no event which, after notice of the lapse of
time, or both, would become such an Event of Default, shall have occurred and be
continuing; and (iii) an officer's certificate and legal opinion covering such
conditions shall be delivered to the Trustee.
 
CERTAIN COVENANTS
 
     Existence.  Except as permitted under " -- Merger, Consolidation or Sale"
above, Parkway is required to do or cause to be done all things necessary to
preserve and keep in full force and effect its existence, rights and franchises;
provided, however, that Parkway shall not be required to preserve any right or
franchise if it determines that the preservation thereof is no longer desirable
in the conduct of its business and that the loss thereof is not disadvantageous
in any material respect to the Holders of the Debt Securities.
 
     Maintenance of Properties.  Parkway is required to cause all of its
material properties used or useful in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and to cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of Parkway may be
                                        8
<PAGE>   21
 
necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
Parkway and its Subsidiaries shall not be prevented from selling or otherwise
disposing for value their respective properties in the ordinary course of
business.
 
     Insurance.  Parkway is required to, and is required to cause each of its
Subsidiaries to, keep all of its insurable properties insured against loss or
damage at least equal to their then full insurable value with financially sound
and reputable insurance companies.
 
     Payment of Taxes and Other Claims.  Parkway is required to pay or discharge
or cause to be paid or discharged, before the same shall become delinquent, (i)
all taxes, assessments and governmental charges levied or imposed upon it or any
Subsidiary or upon its income, profits or property or that of any Subsidiary;
and (ii) all lawful claims for labor, materials and supplies which, if unpaid,
might by law become a lien upon the property of Parkway or any Subsidiary;
provided, however, that Parkway shall not be required to pay or discharge or
cause to be paid or discharged any such tax, assessment, charge or claim whose
amount, applicability or validity is being contested in good faith by
appropriate proceedings.
 
     Provision of Financial Information.  The Holders of Debt Securities will be
provided with copies of the annual reports and quarterly reports of Parkway.
Whether or not Parkway is subject to Sections 13 or 15(d) of the Exchange Act
and for so long as any Debt Securities are outstanding, Parkway will, to the
extent permitted under the Exchange Act, be required to file with the Commission
the annual reports, quarterly reports and other documents which Parkway would
have been required to file with the Commission pursuant to such Sections 13 or
15(d) (the "Financial Statements") if Parkway were so subject, such documents to
be filed with the Commission on or prior to the respective dates (the "Required
Filing Dates") by which Parkway would have been required so to file such
documents if Parkway were so subject. Parkway will also in any event (i) within
15 days of each Required Filing Date (a) transmit by mail to all Holders of Debt
Securities, as their names and addresses appear in the Security Register,
without cost to such Holders, copies of the annual reports and quarterly reports
which Parkway would have been required to file with the Commission pursuant to
Sections 13 or 15(d) of the Exchange Act if Parkway were subject to such
sections and (b) file with the Trustee copies of the annual reports, quarterly
reports and other documents which Parkway would have been required to file with
the Commission pursuant to Sections 13 or 15(d) of the Exchange Act if Parkway
were subject to such sections and (ii) if filing such documents by Parkway with
the Commission is not permitted under the Exchange Act, promptly upon written
request and payment of the reasonable cost of duplication and delivery, supply
copies of such documents to any prospective Holder.
 
     Additional Covenants.  Any additional or different covenants of Parkway
with respect to any series of Debt Securities will be set forth in the
Prospectus Supplement relating thereto.
 
EVENTS OF DEFAULT, NOTICE AND WAIVER
 
     The Indenture provides that the following events are "Events of Default"
with respect to any series of Debt Securities issued thereunder: (i) default for
30 days in the payment of any installment of interest on any Debt Security of
such series; (ii) default in the payment of the principal of (or premium, if
any, on) any Debt Security of such series at its maturity; (iii) default in
making any sinking fund payment as required for any Debt Security of such
series; (iv) default in the performance of any other covenant of Parkway
contained in the Indenture (other than a covenant added to the Indenture solely
for the benefit of a series of Debt Securities issued thereunder other than such
series), such default having continued for 60 days after written notice as
provided in the Indenture; (v) default in the payment of an aggregate principal
amount exceeding $1,000,000 of any evidence of recourse indebtedness of Parkway
or any mortgage, indenture or other instrument under which such indebtedness is
issued or by which such indebtedness is secured, such default having occurred
after the expiration of any applicable grace period and having resulted in the
acceleration of the maturity of such indebtedness, but only if such indebtedness
is not discharged or such acceleration is not rescinded or annulled; (vi)
certain events of bankruptcy, insolvency or reorganization, or court appointment
of a receiver, liquidator or trustee of Parkway or any Significant Subsidiary,
as defined below, or any of their respective property; and (vii) any other Event
of Default provided with respect to a particular series of Debt
 
                                        9
<PAGE>   22
 
Securities. The term "Significant Subsidiary" means each significant subsidiary
(as defined in Regulation S-X promulgated under the Securities Act of 1933, as
amended (the "Securities Act")) of Parkway.
 
     If an Event of Default under the Indenture with respect to Debt Securities
of any series at the time outstanding occurs and is continuing, then in every
such case the Trustee or the Holders of not less than 25% in principal amount of
the Outstanding Debt Securities of that series may declare the principal amount
(or, if the Debt Securities of that series are Original Issue Discount
Securities or Indexed Securities, such portion of the principal amount as may be
specified in the terms thereof) of all of the Debt Securities of that series to
be due and payable immediately by written notice thereof to Parkway (and to the
Trustee if given by the Holders), provided that in the case of an Event of
Default described under clause (vi) of the preceding paragraph, acceleration is
automatic. However, at any time after such a declaration of acceleration with
respect to Debt Securities of such series (or of all Debt Securities then
outstanding under the Indenture, as the case may be) has been made, but before a
judgment or decree for payment of the money due has been obtained by the
Trustee, the Holders of not less than a majority in principal amount of
Outstanding Debt Securities of such series (or of all Debt Securities then
outstanding under the Indenture, as the case may be) may rescind and annul such
declaration and its consequences if (i) Parkway shall have deposited with the
applicable Trustee all required payments of the principal of (and premium, if
any) and interest on the Debt Securities of such series (or of all Debt
Securities then outstanding under the Indenture, as the case may be), plus
certain fees, expenses, disbursements and advances of the Trustee and (ii) all
Events of Default, other than the nonpayment of accelerated principal of (or
specified portion thereof), or premium (if any) or interest on the Debt
Securities of such series (or of all Debt Securities then outstanding under the
Indenture, as the case may be) have been cured or waived as provided in the
Indenture. The Indenture also provides that the Holders of not less than a
majority in principal amount of the Outstanding Debt Securities of any series
(or of all Debt Securities then outstanding under the Indenture, as the case may
be) may waive any past default with respect to such series and its consequences,
except a default (a) in the payment of the principal of (or premium, if any) or
interest on any Debt Security of such series or (b) in respect of a covenant or
provision contained in the Indenture that cannot be modified or amended without
the consent of the Holder of each Outstanding Debt Security affected thereby.
 
     The Trustee will be required to give notice to the Holders of Debt
Securities within 90 days of a default under the Indenture unless such default
has been cured or waived; provided, however, that the Trustee may withhold
notice to the Holders of any series of Debt Securities of any default with
respect to such series (except a default in the payment of the principal of (or
premium, if any) or interest on any Debt Security of such series or in the
payment of any sinking fund installment in respect of any Debt Security of such
series) if specified Responsible Officers of the Trustee consider such
withholding to be in the interest of such Holders.
 
     The Indenture provides that no Holders of Debt Securities of any series may
institute any proceedings, judicial or otherwise, with respect to the Indenture
or for any remedy thereunder, except in the case of failure of the Trustee, for
60 days, to act after it has received a written request to institute proceedings
in respect of an Event of Default from the Holders of not less than 25% in
principal amount of the Outstanding Debt Securities of such series, as well as
an offer of indemnity reasonably satisfactory to it. This provision will not
prevent, however, any holder of Debt Securities from instituting suit for the
enforcement of payment of the principal of (and premium, if any) and interest on
such Debt Securities at the respective due dates thereof.
 
     Subject to provisions in the Indenture relating to its duties in case of
default, the Trustee is under no obligation to exercise any of its rights or
powers under the Indenture at the request or direction of any Holders of any
series of Debt Securities then outstanding under the Indenture, unless such
Holders shall have offered to the Trustee thereunder reasonable security or
indemnity. The Holders of not less than a majority in principal amount of the
Outstanding Debt Securities of any series (or of all Debt Securities then
outstanding under the Indenture, as the case may be) shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or of exercising any trust or power conferred upon the
Trustee. However, the Trustee may refuse to follow any direction which is in
conflict with any law or the Indenture, which may involve the Trustee in
personal liability or which may be unduly prejudicial to the holders of Debt
Securities of such series not joining therein.

     Within 120 days after the close of each fiscal year, Parkway must deliver
to the Trustee a certificate, signed by one of several specified officers of
Parkway, stating whether or not such officer has knowledge of any default under
the Indenture and, if so, specifying each such default and the nature and status
thereof.
 
MODIFICATION OF THE INDENTURE
 
     Modifications and amendments of the Indenture will be permitted to be made
only with the consent of the Holders of not less than a majority in principal
amount of all Outstanding Debt Securities or series of Outstanding Debt
Securities which are affected by such modification or amendment (voting as one
class); provided, however, that no such modification or amendment may, without
the consent of the Holders of each such Debt Security affected thereby, (i)
change the Stated Maturity of the principal of, or premium (if any) or any
installment of interest on, any such Debt Security; (ii) reduce the principal
amount of, or the rate or amount of interest on, or any premium payable on
redemption of, any such Debt Security, or reduce the amount of principal of an
Original Issue Discount Security that would be due and payable upon declaration
of acceleration of the maturity thereof or would be provable in bankruptcy, or
adversely affect any right of repayment of the holder of any such Debt Security;
(iii) change the place of payment, or the coin or currency, for payment of
principal of, premium, if any, or interest on any such Debt Security; (iv)
impair the right to institute suit for the enforcement of any payment on or with
respect to any such Debt Security; (v) reduce the above stated percentage of
outstanding Debt Securities of any series necessary to modify or amend the
Indenture, to waive compliance with certain provisions thereof or certain
defaults and consequences thereunder or to reduce the quorum or voting
requirements set forth in the Indenture; or (vi) modify any of the foregoing
provisions or any of the provisions relating to the waiver of certain past
defaults or certain covenants, except to increase the required percentage to
effect such action or to provide that certain other provisions may not be
modified or waived without the consent of the Holders of such Debt Security.
 
     The Indenture provides that the Holders of not less than a majority in
principal amount of a series of Outstanding Debt Securities have the right to
waive compliance by Parkway with certain covenants relating to such series of
Debt Securities in the Indenture.
 
     Modifications and amendments of the Indenture will be permitted to be made
by Parkway and the Trustee without the consent of any Holder of Debt Securities
for any of the following purposes: (i) to evidence the succession of another
Person to Parkway as obligor under the Indenture; (ii) to add to the covenants
of Parkway for the benefit of the Holders of all or any series of Debt
Securities or to surrender any right or power conferred upon Parkway in the
Indenture; (iii) to add Events of Default for the benefit of the Holders of all
or any series of Debt Securities; (iv) to add or change any provisions of the
Indenture to facilitate the issuance of, or to liberalize certain terms of, Debt
Securities in bearer form, or to permit or facilitate the issuance of Debt
Securities in uncertificated form, provided, that such action shall not
adversely affect the interests of the Holders of the Debt Securities of any
series in any material respect; (v) to change or eliminate any provisions of the
Indenture, provided that any such change or elimination shall become effective
only when there are no Debt Securities Outstanding of any series created prior
thereto which are entitled to the benefit of such provision; (vi) to secure the
Debt Securities; (vii) to establish the form or terms of Debt Securities of any
series; (viii) to provide for the acceptance of appointment by a successor
Trustee or facilitate the administration of the trusts under the Indenture by
more than one Trustee; (ix) to cure any ambiguity, defect or inconsistency in
the Indenture, provided that such action shall not adversely affect the
interests of Holders of Debt Securities of any series in any material respect;
or (x) to supplement any of the provisions of the Indenture to the extent
necessary to permit or facilitate defeasance and discharge of any series of such
Debt Securities, provided that such action shall not adversely affect the
interests of the Holders of the Debt Securities of any series in any material
respect.
 
     The Indenture provides that in determining whether the Holders of the
requisite principal amount of Outstanding Debt Securities of a series have given
any request, demand, authorization, direction, notice, consent or waiver
thereunder or whether a quorum is present at a meeting of Holders of Debt
Securities, (i) the principal amount of an Original Issue Discount Security that
shall be deemed to be outstanding shall be the amount of the principal thereof
that would be due and payable as of the date of such determination upon
declaration of acceleration of the maturity thereof; (ii) the principal amount
of a Debt Security
                                       11
<PAGE>   24
 
denominated in a foreign currency that shall be deemed outstanding shall be the
U.S. dollar equivalent, determined on the issue date for such Debt Security, of
the principal amount (or, in the case of an Original Issue Discount Security,
the U.S. dollar equivalent on the issue date of such Debt Security of the amount
determined as provided in (i) above); (iii) the principal amount of an Indexed
Security that shall be deemed outstanding shall be the principal face amount of
such Indexed Security at original issuance, unless otherwise provided with
respect to such Indexed Security pursuant to the Indenture; and (iv) Debt
Securities owned by Parkway or any other obligor upon the Debt Securities or any
affiliate to Parkway or of such other obligor shall be disregarded.
 
     The Indenture contains provisions for convening meetings of the Holders of
Debt Securities of a series. A meeting will be permitted to be called at any
time by the Trustee, and also, upon request, by Parkway or the holders of at
least 25% in principal amount of the Outstanding Debt Securities of such series,
in any such case upon notice given as provided in the Indenture. Except for any
consent that must be given by the Holder of each Debt Security affected by
certain modifications and amendments of the Indenture, any resolution presented
at a meeting or adjourned meeting duly reconvened at which a quorum is present
will be permitted to be adopted by the affirmative vote of the Holders of a
majority in principal amount of the Outstanding Debt Securities of that series;
provided, however, that, except as referred to above, any resolution with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that may be made, given or taken by the Holders of a
specified percentage, which is less than a majority, in principal amount of the
Outstanding Debt Securities of a series may be adopted at a meeting or adjourned
meeting duly reconvened at which a quorum is present by the affirmative vote of
the Holders of such specified percentage in principal amount of the Outstanding
Debt Securities of that series. Any resolution passed or decision taken at any
meeting of Holders of Debt Securities of any series duly held in accordance with
the Indenture will be binding on all Holders of Debt Securities of that series.
The quorum at any meeting called to adopt a resolution, and at any reconvened
meeting, will be Persons holding or representing a majority in principal amount
of the Outstanding Debt Securities of a series; provided, however, that if any
action is to be taken at such meeting with respect to a consent or wavier which
may be given by the Holders of not less than a specified percentage in principal
amount of the Outstanding Debt Securities of a series, the Persons holding or
representing such specified percentage in principal amount of the Outstanding
Debt Securities of such series will constitute a quorum.
 
     Notwithstanding the foregoing provisions, if any action is to be taken at a
meeting of Holders of Debt Securities of any series with respect to any request,
demand, authorization, direction, notice, consent, waiver or other action that
the Indenture expressly provides may be made, given or taken by the Holders of a
specified percentage in principal amount of all Outstanding Debt Securities
affected thereby, or of the Holders of such series and one or more additional
series: (i) there shall be no minimum quorum requirement for such meeting and
(ii) the principal amount of the Outstanding Debt Securities of such series that
vote in favor of such request, demand, authorization, direction, notice,
consent, waiver or other action shall be taken into account in determining
whether such request, demand, authorization, direction, notice, consent, waiver
or other action has been made, given or taken under the Indenture.
 
DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE
 
     Parkway may discharge certain obligations to Holders of any series of Debt
Securities that have not already been delivered to the Trustee for cancellation
and that either have become due and payable or will become due and payable
within one year (or scheduled for redemption within one year) by irrevocably
depositing with the Trustee, in trust, funds in such currency or currencies,
currency unit or units or composite currency or currencies in which such Debt
Securities are payable in an amount sufficient to pay the entire indebtedness on
such Debt Securities in respect of principal (and premium, if any) and interest
to the date of such deposit (if such Debt Securities have become due and
payable) or to the Stated Maturity or Redemption Date, as the case may be.
 
     The Indenture provides that, if the provisions of Article Fourteen are made
applicable to the Debt Securities of or within any series pursuant to the
Indenture, Parkway may elect either (i) to defease and be discharged from any
and all obligations with respect to such Debt Securities (except for the
obligation to pay
                                       12
<PAGE>   25
 
additional amounts, if any, upon the occurrence of certain events of tax,
assessment or governmental charge with respect to payments on such Debt
Securities and the obligations to register the transfer or exchange of such Debt
Securities, to replace temporary or mutilated, destroyed, lost or stolen Debt
Securities, to maintain an office or agency in respect of such Debt Securities
and to hold moneys for payment in trust) ("defeasance") or (ii) to be released
from its obligations with respect to such Debt Securities under the Indenture
(including the restrictions described under " -- Certain Covenants" above) and
its obligations with respect to any other covenant, and any omission to comply
with such obligations shall not constitute a default or an Event of Default with
respect to such Debt Securities ("covenant defeasance"), in either case upon the
irrevocable deposit by Parkway with the Trustee, in trust, of an amount, in such
currency or currencies, currency unit or units or composite currency or
currencies in which such Debt Securities are payable at Stated Maturity, or
Government Obligations (as defined below), or both, applicable to such Debt
Securities which through the scheduled payment of principal and interest in
accordance with their terms will provide money in an amount sufficient to pay
the principal of (and premium, if any) and interest on such Debt Securities, and
any mandatory sinking fund or analogous payments thereon, on the scheduled due
dates therefor.
 
     Such a trust will only be permitted to be established if, among other
things, Parkway has delivered to the Trustee an Opinion of Counsel (as specified
in the Indenture) to the effect that the Holders of such Debt Securities will
not recognize income, gain or loss for U.S. federal income tax purposes as a
result of such defeasance or covenant defeasance and will be subject to U.S.
federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such defeasance or covenant defeasance had not
occurred, and such Opinion of Counsel, in the case of defeasance, must refer to
and be based upon a ruling of the Internal Revenue Service ("Service") or a
change in applicable United States Federal income tax law occurring after the
date of the Indenture.
 
     "Government Obligations" means securities which are (i) direct obligations
of the United States of America or the government which issued the foreign
currency in which the Debt Securities of a particular series are payable, for
the payment of which its full faith and credit is pledged or (ii) obligations of
a person controlled or supervised by and acting as an agency or instrumentality
of the United States of America or such government which issued the foreign
currency in which the Debt Securities of such series are payable, the payment of
which is unconditionally guaranteed as a full faith and credit obligation by the
United States of America or such other government, which, in either case, are
not callable or redeemable at the option of the issuer thereof, and shall also
include a depository receipt issued by a bank or trust company as custodian with
respect to any such Government Obligation or a specific payment of interest on
or principal of any such Government Obligations held by such custodian for the
account of the holder of a depository receipt, provided that (except as required
by law) such custodian is not authorized to make any deduction from the amount
payable to the holder of such depository receipt from any amount received by the
custodian in respect of the Government Obligation or the specific payment of
interest on or principal of the Government Obligation evidenced by such
depository receipt.
 
     Unless otherwise provided in the applicable Prospectus Supplement, if after
Parkway has deposited funds and/or Government Obligations to effect defeasance
or covenant defeasance with respect to Debt Securities of any series: (i) the
Holder of a Debt Security of such series is entitled to, and does, elect
pursuant to the Indenture or the terms of such Debt Security to receive payment
in a currency, currency unit or composite currency other than that in which such
deposit has been made in respect of such Debt Security; or (ii) a Conversion
Event (as defined below) occurs in respect of the currency, currency unit or
composite currency in which such deposit has been made, the indebtedness
represented by such Debt Security shall be deemed to have been, and will be,
fully discharged and satisfied through the payment of the principal of (and
premium, if any) and interest on such Debt Security as they become due out of
the proceeds yielded by converting the amount so deposited in respect of such
Debt Security into the currency, currency unit or composite currency in which
such Debt Security becomes payable as a result of such election or such
Conversion Event based on the applicable market exchange rate. "Conversion
Event" means the cessation of use of (i) a currency, currency unit or composite
currency both by the government of the country which issued such currency and
for the settlement of transactions by a central bank or other public
institutions of or within the international banking community; (ii) the European
Currency Unit as defined and revised from time to time by the Council
 
                                       13
<PAGE>   26
 
of the European Community ("ECU"), both within the European Monetary System and
for the settlement of transactions by public institutions of or within the
European Community; or (iii) any currency unit or composite currency other than
the ECU for the purposes for which it was established.
 
     Unless otherwise provided in the applicable Prospectus Supplement, all
payments of principal of (and premium, if any) and interest on any Debt Security
that is payable in a foreign currency that ceases to be used by its government
of issuance shall be made in U.S. dollars.
 
     In the event Parkway effects covenant defeasance with respect to any Debt
Securities and such Debt Securities are declared due and payable because of the
occurrence of any Event of Default other than the Event of Default described in
clause (iv) under " -- Events of Default, Notice and Waiver" or described in
clause (vii) under "-- Events of Default, Notice and Waiver" with respect to any
other covenant as to which there has been covenant defeasance, the amount in
such currency, currency unit or composite currency in which such Debt securities
are payable, and Government Obligations on deposit with the Trustee, will be
sufficient to pay amounts due on such Debt Securities at the time of their
Stated Maturity but may not be sufficient to pay amounts due on such Debt
Securities at the time of the acceleration resulting from such event of Default.
However, Parkway would remain liable to make payment of such amounts due at the
time of acceleration.
 
     The applicable Prospectus Supplement may further describe the provisions,
if any, permitting such defeasance or covenant defeasance, including any
modification to the provisions described above, with respect to the Debt
Securities of or within a particular series.
 
CONVERSION RIGHTS
 
     The terms and conditions, if any, upon which any of the Debt Securities are
convertible into capital stock of or equity interest in Parkway will be set
forth in the applicable Prospectus Supplement relating thereto. Such terms will
include the amount of capital stock of or equity interest in Parkway into which
the Debt Securities are convertible, the conversion price (or manner of
calculation thereof), the conversion period, provisions as to whether
conversions will be at the option of the holders of the Debt Securities or
Parkway, the events requiring an adjustment of the conversion price and
provisions affecting conversion in the event of the redemption of such Debt
Securities and any restrictions on conversion, including restrictions directed
at maintaining Parkway's REIT status.
 
GLOBAL SECURITIES
 
     The Debt Securities of a series may be issued in whole or in part in the
form of one or more global securities (the "Global Securities") that will be
deposited with, or on behalf of, a depositary (the "Depositary") identified in
the applicable Prospectus Supplement relating to such series. Global Securities
may be issued in either registered or bearer form and in either temporary or
permanent form. The specific terms of the depositary arrangement with respect to
a series of Debt Securities will be described in the applicable Prospectus
Supplement relating to such series.

          (x) Whether interests in such Preferred Shares will be represented by

of Common Shares of Parkway, and to all equity securities ranking junior to such
Preferred Shares; (ii) on a parity with all equity securities issued by Parkway
the terms of which specifically provide that such equity securities rank on a
parity with the Preferred Shares; and (iii) junior to all equity securities

                                       15
<PAGE>   28
 
DIVIDENDS
 
     Holders of Preferred Shares of each series will be entitled to receive,
when, as and if declared by the Board of Directors of Parkway, out of assets of
Parkway legally available for payment, cash dividends at such rates and on such
dates as will be set forth in the applicable Prospectus Supplement. Each such
dividend shall be payable to holders of record as they appear on the share
transfer books of Parkway on such record dates as shall be fixed by the Board of
Directors of Parkway.
 
     Dividends on any series of Preferred Shares may be cumulative or
non-cumulative, as provided in the applicable Prospectus Supplement. Dividends,
if cumulative, will be cumulative from and after the date set forth in the
applicable Prospectus Supplement. If the Board of Directors of Parkway fails to
declare a dividend payable on a dividend payment date on any series of the
Preferred Shares for which dividends are non-cumulative, then the holders of
such series of the Preferred Shares will have no right to receive a dividend in
respect of the dividend period ending on such dividend payment date, and Parkway
will have no obligation to pay the dividend accrued for such period, whether or
not dividends on such series are declared payable on any future dividend payment
date.
 
     If Preferred Shares of any series are outstanding, no dividends will be
declared or paid or set apart for payment on any capital stock of Parkway of any
other series ranking, as to dividends, on a parity with or junior to the
Preferred Shares of such series for any period unless (i) if such series of
Preferred Shares has a cumulative dividend, full cumulative dividends have been
or contemporaneously are declared and paid or declared and a sum sufficient for
the payment thereof set apart for such payment on the Preferred Shares of such
series for all past dividend periods and the then current dividend period or
(ii) if such series of Preferred Shares does not have a cumulative dividend,
full dividends for the then current dividend period have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for such payment on the Preferred Shares of such
series. When dividends are not paid in full (or a sum sufficient for such full
payment is not so set apart) upon Preferred Shares of any series and the shares
of any other series of Preferred Shares ranking on a parity as to dividends with
the Preferred Shares of such series, all dividends declared upon Preferred
Shares of such series and any other series of Preferred Shares ranking on a
parity as to dividends with such Preferred Shares shall be declared pro rata so
that the amount of dividends declared per share of Preferred Shares of such
series and such other series of Preferred Shares shall in all cases bear to each
other the same ratio that accrued dividends per share on the Preferred Shares of
such series (which shall not include any accumulation in respect of unpaid
dividends for prior dividend periods if such Preferred Shares do not have a
cumulative dividend) and such other series of Preferred Shares bear to each
other. No interest, or sum of money in lieu of interest, shall be payable in
respect of any dividend payment or payments on Preferred Shares of such series
which may be in arrears.
 
     Except as provided in the immediately preceding paragraph, unless (i) if
such series of Preferred Shares has a cumulative dividend, full cumulative
dividends on the Preferred Shares of such series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
set apart for payment for all past dividend periods and the then current
dividend period; and (ii) if such series of Preferred Shares does not have a
cumulative dividend, full dividends on the Preferred Shares of such series have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof set apart for payment for the then current dividend
period, no dividends (other than in Common Shares or other capital shares
ranking junior to the Preferred Shares of such series as to dividends and upon
liquidation) shall be declared or paid or set aside for payment or other
distribution shall be declared or made upon the Common Shares, or any other
capital shares of Parkway ranking junior to or on a parity with the Preferred
Shares of such series as to dividends or upon liquidation, nor shall any Common
Shares, or any other capital shares of Parkway ranking junior to or on a parity
with the Preferred Shares of such series as to dividends or upon liquidation be
redeemed, purchased or otherwise acquired for any consideration (or any moneys
be paid to or made available for a sinking fund for the redemption of any such
shares) by Parkway (except by conversion into or exchange for other capital
shares of Parkway ranking junior to the Preferred Shares of such series as to
dividends and upon liquidation). Any dividend payment made on a series of
Preferred Shares shall first be credited against the earliest accrued but unpaid
dividend due with respect to shares of such series which remain payable.
                                       16
<PAGE>   29
 
REDEMPTION
 
     If so provided in the applicable Prospectus Supplement, the Preferred
Shares will be subject to mandatory redemption or redemption at the option of
Parkway, as a whole or in part, in each case upon the terms, at the times and at
the redemption prices set forth in such Prospectus Supplement.
 
     The Prospectus Supplement relating to a series of Preferred Shares that is
subject to mandatory redemption will specify the number of such Preferred Shares
that shall be redeemed by Parkway in each year commencing after a date to be
specified, at a redemption price per share to be specified, together with an
amount equal to all accrued and unpaid dividends thereon (which shall not, if
such Preferred Shares do not have a cumulative dividend, include any
accumulation in respect of unpaid dividends for prior dividend periods) to the
date of redemption. The redemption price may be payable in cash or other
property, as specified in the applicable Prospectus Supplement. If the
redemption price for Preferred Shares of any series is payable only from the net
proceeds of the issuance of capital shares of Parkway, the terms of such
Preferred Shares may provide that, if no such capital shares have been issued or
to the extent the net proceeds from any issuance are insufficient to pay in full
the aggregate redemption price then due, such Preferred Shares shall
automatically and mandatorily be converted into the applicable capital shares of
Parkway pursuant to conversion provisions specified in the applicable Prospectus
Supplement.
 
     Notwithstanding the foregoing, unless (i) if such series of Preferred
Shares has a cumulative dividend, full cumulative dividends on all shares of any
series of Preferred Shares have been or contemporaneously are declared and paid
or declared and a sum sufficient for the payment thereof set apart for payment
for all past dividend periods and the then current dividend period; and (ii) if
such series of Preferred Shares does not have a cumulative dividend, full
dividends of the Preferred Shares of any series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
set apart for payment for the then current dividend period, no shares of any
series of Preferred Shares shall be redeemed unless all outstanding Preferred
Shares of such series is simultaneously redeemed; provided, however, that the
foregoing shall not prevent the purchase or acquisition of Preferred Shares of
such series to preserve the REIT status of Parkway or pursuant to a purchase or
exchange offer made on the same terms to holders of all outstanding Preferred
Shares of such series. In addition, unless (i) if such series of Preferred
Shares has a cumulative dividend, full cumulative dividends on all outstanding
shares of any series of Preferred Shares have been or contemporaneously are
declared and paid or declared and a sum sufficient for the payment thereof set
apart for payment for all past dividend periods and the then current dividend
period; and (ii) if such series of Preferred Shares does not have a cumulative
dividend, full dividends on the Preferred Shares of any series have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for payment for the then current dividend period,
Parkway shall not purchase or otherwise acquire directly or indirectly any
Preferred Shares of such series (except by conversion into or exchange for
capital stock of Parkway ranking junior to the Preferred Shares of such series
as to dividends and upon liquidation); provided, however, that the foregoing
shall not prevent the purchase or acquisition of Preferred Shares of such series
to preserve the REIT status of Parkway or pursuant to a purchase or exchange
offer made on the same terms to holders of all outstanding Preferred Shares of
such series.
 
     If fewer than all of the outstanding Preferred Shares of any series are to
be redeemed, the number of shares to be redeemed will be determined by Parkway
and such shares may be redeemed pro rata from the holders of record of such
shares in proportion to the number of such shares held or for which redemption
is requested by such holder (with adjustments to avoid redemption of fractional
shares) or by lot in a manner determined by Parkway.
 
     Notice of redemption will be mailed at least 30 days but not more than 60
days before the redemption date to each holder of record of Preferred Shares of
any series to be redeemed at the address shown on the share transfer books of
Parkway. Each notice shall state: (i) the redemption date; (ii) the number of
shares and series of the Preferred Shares to be redeemed; (iii) the redemption
price; (iv) the place or places where certificates for such Preferred Shares are
to be surrendered for payment of the redemption price; (v) that dividends on the
shares to be redeemed will cease to accrue on such redemption date; and (vi) the
date upon which the holder's conversion rights, if any, as to such shares shall
terminate. If fewer than all the Preferred

Shares of any series are to be redeemed, the notice mailed to each such holder
thereof shall also specify the number of Preferred Shares to be redeemed from
each such holder. If notice of redemption of any Preferred Shares has been given
and if the funds necessary for such redemption have been set aside by Parkway in
trust for the benefit of the holders of any Preferred Shares so called for
redemption, then from and after the redemption date dividends will cease to
accrue on such Preferred Shares, and all rights of the holders of such shares
will terminate, except the right to receive the redemption price.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the affairs of Parkway, then, before any distribution or payment shall be made
to the holders of any Common Shares or any other class or series of capital
shares of Parkway ranking junior to the Preferred Shares in the distribution of
assets upon any liquidation, dissolution or winding up of Parkway, the holders
of each series of Preferred Shares shall be entitled to receive out of assets of
Parkway legally available for distribution to stockholders liquidating
distributions in the amount of the liquidation preference per share (set forth
in the applicable Prospectus Supplement), plus an amount equal to all dividends
accrued and unpaid thereon (which shall not include any accumulation in respect
of unpaid dividends for prior dividend periods if such Preferred Shares do not
have a cumulative dividend). After payment of the full amount of the liquidating
distributions to which they are entitled, the holders of Preferred Shares will
have no right or claim to any of the remaining assets of Parkway. In the event
that, upon any such voluntary or involuntary liquidation, dissolution or winding
up, the available assets of Parkway are insufficient to pay the amount of the
liquidating distributions on all outstanding Preferred Shares and the
corresponding amounts payable on all shares of other classes or series of
capital shares of Parkway ranking on a parity with the Preferred Shares in the
distribution of assets, then the holders of the Preferred Shares and all other
such classes or series of capital shares shall share ratably in any such
distribution of assets in proportion to the full liquidating distributions to
which they would otherwise be respectively entitled.
 
     If liquidating distributions shall have been made in full to all holders of
Preferred Shares, the remaining assets of Parkway shall be distributed among the
holders of any other classes or series of capital shares ranking junior to the
Preferred Shares upon liquidation, dissolution or winding up, according to their
respective rights and preferences and in each case according to their respective
number of shares. For such purposes, the consolidation or merger of Parkway with
or into any other corporation, trust or entity, or the sale, lease or conveyance
of all or substantially all of the property or business of Parkway, shall not be
deemed to constitute a liquidation, dissolution or winding up of Parkway.
 
VOTING RIGHTS
 
     Holders of Preferred Shares will not have any voting rights, except as set
forth below or as otherwise from time to time required by law or as indicated in
the applicable Prospectus Supplement.
 
     Whenever dividends on any Preferred Shares shall be in arrears for six or
more consecutive quarterly periods, the holders of such Preferred Shares (voting
separately as a class with all other series of Preferred Shares upon which like
voting rights have been conferred and are exercisable) will be entitled to vote
for the election of two additional trustees of Parkway at a special meeting
called by the holders of record of at least ten percent (10%) of any series of
Preferred Shares so in arrears (unless such request is received less than 90
days before the date fixed for the next annual or special meeting of the
stockholders) or at the next annual meeting of stockholders, and at each
subsequent annual meeting until (i) if such series of Preferred Shares has a
cumulative dividend, all dividends accumulated on such Preferred Shares for the
past dividend periods and the then current dividend period shall have been fully
paid or declared and a sum sufficient for the payment thereof set aside for
payment or (ii) if such series of Preferred Shares does not have a cumulative
dividend, four consecutive quarterly dividends shall have been fully paid or
declared and a sum sufficient for the payment thereof set aside for payment. In
such case, the entire Board of Directors of Parkway will be increased by two
directors.
 
                                       18
<PAGE>   31
 
     Unless provided otherwise for any series of Preferred Shares, so long as
any Preferred Shares remain outstanding, Parkway will not, without the
affirmative vote or consent of the holders of at least two-thirds of the shares
of each series of Preferred Shares outstanding at the time, given in person or
by proxy, either in writing or at a meeting (such series voting separately as a
class), (i) authorize or create, or increase the authorized or issued amount of,
any class or series of capital stock ranking prior to such series of Preferred
Shares with respect to payment of dividends or the distribution of assets upon
liquidation, dissolution or winding up or reclassify any authorized capital
stock of Parkway into such shares, or create, authorize or issue any obligation
or security convertible into or evidencing the right to purchase any such
shares; or (ii) amend, alter or repeal the provisions of the Charter or the
Designating Amendment for such series of Preferred Shares, whether by merger,
consolidation or otherwise (an "Event"), so as to materially and adversely
affect any right, preference, privilege or voting power of such series of
Preferred Shares or the holder thereof; provided, however, as to the occurrence
of any of the Events set forth in (ii) above, so long as the Preferred Shares
remain outstanding with the terms thereof materially unchanged, taking into
account that upon the occurrence of an Event, Parkway may not be the surviving
entity, the occurrence of any such Event shall not be deemed to materially and
adversely affect such rights, preferences, privileges or voting power of holders
of Preferred Shares and provided further that (a) any increase in the amount of
the authorized Preferred Shares or the creation or issuance of any other series
of Preferred Shares; or (b) any increase in the amount of authorized shares of
such series or any other series of Preferred Shares, in each case ranking on a
parity with or junior to the Preferred Shares of such series with respect to
payment of dividends or the distribution of assets upon liquidation, dissolution
or winding up, shall not be deemed to materially and adversely affect such
rights, preferences, privileges or voting powers.
 
     The foregoing voting provisions will not apply if, at or prior to the time
when the act with respect to which such vote would otherwise be required shall
be effected all outstanding shares of such series of Preferred Shares shall have
been redeemed or called for redemption and sufficient funds shall have been
deposited in trust to effect such redemption.
 
     Under Maryland law, notwithstanding anything to the contrary set forth
above, holders of each series of Preferred Shares will be entitled to vote upon
any proposed amendment to the Charter if the amendment would change the contract
rights of such shares as expressly set forth in the Charter.
 
CONVERSION RIGHTS
 
     The terms and conditions, if any, upon which any series of Preferred Shares
are convertible into Common Shares will be set forth in the applicable
Prospectus Supplement relating thereto. Such terms will include the number of
Common Shares into which the Preferred Shares are convertible, the conversion
price (or manner of calculation thereof), the conversion period, provisions as
to whether conversions will be at the option of the holders of the Preferred
Shares or Parkway, the events requiring an adjustment of the conversion price
and provisions affecting conversion in the event of the redemption of such
series of Preferred Shares.
 
STOCKHOLDER LIABILITY
 
     As discussed below under "Description of Common Shares -- General,"
applicable Maryland law provides that no stockholder, including holders of
Preferred Shares, will be personally liable for the acts and obligations of
Parkway and that the funds and property of Parkway will be the only recourse for
such acts or obligations.
 
RESTRICTIONS ON OWNERSHIP
 
     As discussed below under "Description of Common Shares -- Restrictions on
Transfer," for Parkway to qualify as a REIT under the Internal Revenue Code of
1986, as amended (the "Code"), not more than 50% in value of its outstanding
capital shares may be owned, directly or indirectly, by five or fewer
individuals (as defined in the Code to include certain entities) during the last
half of a taxable year. To assist Parkway in meeting this requirement, Parkway
may take certain actions to limit the beneficial ownership, directly or
indirectly, by a single person of Parkway's outstanding equity securities,
including any Preferred Shares of
 
                                       19
<PAGE>   32
 
Parkway. Therefore, the Designating Amendment for each series of Preferred
Shares may contain provisions restricting the ownership and transfer of the
Preferred Shares. The applicable Prospectus Supplement will specify any
additional ownership limitation relating to a series of Preferred Shares.
 
REGISTRAR AND TRANSFER AGENT
 
     The Registrar and Transfer Agent for the Preferred Shares will be set forth
in the applicable Prospectus Supplement.
 
                        DESCRIPTION OF DEPOSITARY SHARES
 
GENERAL
 
     Parkway may issue receipts ("Depositary Receipts") for Depositary Shares,
each of which will represent a fractional interest of a share of a particular
series of Preferred Shares, as specified in the applicable Prospectus
Supplement. Preferred Shares of each series represented by Depositary Shares
will be deposited under a separate deposit agreement (each, a "Deposit
Agreement") among Parkway, the depositary named therein (a "Preferred Shares
Depositary"), and the holders from time to time of the Depositary Receipts.
Subject to the terms of the applicable Deposit Agreement, each owner of a
Depositary Receipt will be entitled, in proportion to the fractional interest of
a share of a particular series of Preferred Shares represented by the Depositary
Shares evidenced by such Depositary Receipt, to all the rights and preferences
of the Preferred Shares represented by such Depositary Shares (including
dividend, voting, conversion, redemption and liquidation rights).
 
     The Depositary Shares will be evidenced by Depositary Receipts issued
pursuant to the applicable Deposit Agreement. Immediately following the issuance
and delivery of the Preferred Shares by Parkway to a Preferred Shares
Depositary, Parkway will cause such Preferred Shares Depositary to issue, on
behalf of Parkway, the Depositary Receipts. Copies of the applicable form of
Deposit Agreement and Depositary Receipt may be obtained from Parkway upon
request, and the statements made hereunder relating to Deposit Agreements and
the Depositary Receipts to be issued thereunder are summaries of certain
anticipated provisions thereof and do not purport to be complete and are subject
to, and qualified in their entirety by reference to, all of the provisions of
the applicable Deposit Agreement and related Depositary Receipts.
 
DIVIDENDS AND OTHER DISTRIBUTIONS
 
     A Preferred Shares Depositary will be required to distribute all cash
dividends or other cash distributions received in respect of the applicable
Preferred Shares to the record holders of Depositary Receipts evidencing the
related Depositary Shares in proportion to the number of such Depositary
Receipts owned by such holders, subject to certain obligations of holders to
file proofs, certificates and other information and to pay certain charges and
expenses to such Preferred Shares Depositary.
 
     In the event of a distribution other than in cash, a Preferred Shares
Depositary will be required to distribute property received by it to the record
holders of Depositary Receipts entitled thereto, subject to certain obligations
of holders to file proofs, certificates and other information and to pay certain
charges and expenses to such Preferred Shares Depositary, unless such Preferred
Shares Depositary determines that it is not feasible to make such distribution,
in which case such Preferred Shares Depositary may, with the approval of
Parkway, sell such property and distribute the net proceeds from such sale to
such holders.
 
     No distribution will be made in respect of any Depositary Share to the
extent that it represents any Preferred Shares which have been converted or
exchanged.
 
WITHDRAWAL OF SHARES
 
     Upon surrender of the Depositary Receipts at the corporate trust office of
the applicable Preferred Shares Depositary (unless the related Depositary Shares
have previously been called for redemption or converted), the holders thereof
will be entitled to delivery at such office, to or upon each such holder's
order, of the
                                       20
<PAGE>   33
 
number of whole or fractional shares of the applicable Preferred Shares and any
money or other property represented by the Depositary Shares evidenced by such
Depositary Receipts. Holders of Depositary Receipts will be entitled to receive
whole or fractional shares of the related Preferred Shares on the basis of the
proportion of Preferred Shares represented by each Depositary Share as specified
in the applicable Prospectus Supplement, but holders of such Preferred Shares
will not thereafter be entitled to receive Depositary Shares therefor. If the
Depositary Receipts delivered by the holder evidence a number of Depositary
Shares in excess of the number of Depositary Shares representing the number of
Preferred Shares to be withdrawn, the applicable Preferred Shares Depositary
will be required to deliver to such holder at the same time a new Depositary
Receipt evidencing such excess number of Depositary Shares.
 
REDEMPTION OF DEPOSITARY SHARES
 
     Whenever Parkway redeems Preferred Shares held by a Preferred Shares
Depositary, such Preferred Shares Depositary will be required to redeem as of
the same redemption date the number of Depositary Shares representing the
Preferred Shares so redeemed, provided Parkway shall have paid in full to such
Preferred Shares Depositary the redemption price of the Preferred Shares to be
redeemed plus an amount equal to any accrued and unpaid dividends thereon to the
date fixed for redemption. The redemption price per Depositary Share will be
equal to the redemption price and any other amounts per share payable with
respect to the Preferred Shares. If fewer than all the Depositary Shares are to
be redeemed, the Depositary Shares to be redeemed will be selected pro rata (as
nearly as may be practicable without creating fractional Depositary Shares) or
by any other equitable method determined by Parkway that preserves the REIT
status of Parkway.
 
     From and after the date fixed for redemption, all dividends in respect of
the Preferred Shares so called for redemption will cease to accrue, the
Depositary Shares so called for redemption will no longer be deemed to be
outstanding and all rights of the holders of the Depositary Receipts evidencing
the Depositary Shares so called for redemption will cease, except the right to
receive any moneys payable upon such redemption and any money or other property
to which the holders of such Depositary Receipts were entitled upon such
redemption upon surrender thereof to the applicable Preferred Shares Depositary.
 
VOTING OF THE PREFERRED SHARES
 
     Upon receipt of notice of any meeting at which the holders of the
applicable Preferred Shares are entitled to vote, a Preferred Shares Depositary
will be required to mail the information contained in such notice of meeting to
the record holders of the Depositary Receipts evidencing the Depositary Shares
which represent such Preferred Shares. Each record holder of Depositary Receipts
evidencing Depositary Shares on the record date (which will be the same date as
the record date for the Preferred Shares) will be entitled to instruct such
Preferred Shares Depositary as to the exercise of the voting rights pertaining
to the amount of Preferred Shares represented by such holder's Depositary
Shares. Such Preferred Shares Depositary will be required to vote the amount of
Preferred Shares represented by such Depositary Shares in accordance with such
instructions, and Parkway will agree to take all reasonable action which may be
deemed necessary by such Preferred Shares Depositary in order to enable such
Preferred Shares Depositary to do so. Such Preferred Shares Depositary will be
required to abstain from voting the amount of Preferred Shares represented by
such Depositary Shares to the extent it does not receive specific instructions
from the holders of Depositary Receipts evidencing such Depositary Shares. A
Preferred Shares Depositary will not be responsible for any failure to carry out
any instruction to vote, or for the manner or effect of any such vote made, as
long as any such action or nonaction is in good faith and does not result from
negligence or willful misconduct of such Preferred Shares Depositary.
 
LIQUIDATION PREFERENCE
 
     In the event of the liquidation, dissolution or winding up of Parkway,
whether voluntary or involuntary, the holders of each Depositary Receipt will be
entitled to the fraction of the liquidation preference accorded each Preferred
Share represented by the Depositary Share evidenced by such Depositary Receipt,
as set forth in the applicable Prospectus Supplement.
 
                                       21
<PAGE>   34
 
CONVERSION OF PREFERRED SHARES
 
     The Depositary Shares, as such, will not be convertible into Common Shares
or any other securities or property of Parkway. Nevertheless, if so specified in
the applicable Prospectus Supplement relating to an offering of Depositary
Shares, the Depositary Receipts may be surrendered by holders thereof to the
applicable Preferred Shares Depositary with written instructions to such
Preferred Shares Depositary to instruct Parkway to cause conversion of the
Preferred Shares represented by the Depositary Shares evidenced by such
Depositary Receipts into whole Common Shares, other Preferred Shares or other
shares of stock, and Parkway will agree that upon receipt of such instructions
and any amounts payable in respect thereof, it will cause the conversion thereof
utilizing the same procedures as those provided for delivery of Preferred Shares
to effect such conversion. If the Depositary Shares evidenced by a Depositary
Receipt are to be converted in part only, a new Depositary Receipt or Receipts
will be issued for any Depositary Shares not to be converted. No fractional
Common Shares will be issued upon conversion, and if such conversion will result
in a fractional share being issued, an amount will be paid in cash by Parkway
equal to the value of the fractional interest based upon the closing price of
the Common Shares on the last business day prior to the conversion.
 
AMENDMENT AND TERMINATION OF A DEPOSIT AGREEMENT
 
     Any form of Depositary Receipt evidencing Depositary Shares which will
represent Preferred Shares and any provision of a Deposit Agreement will be
permitted at any time to be amended by agreement between Parkway and the
applicable Preferred Shares Depositary. However, any amendment that materially
and adversely alters the rights of the holders of Depositary Receipts or that
would be materially and adversely inconsistent with the rights granted to the
holders of the related Preferred Shares will not be effective unless such
amendment has been approved by the existing holders of at least two-thirds of
the applicable Depositary Shares evidenced by the applicable Depositary Receipts
then outstanding. No amendment shall impair the right, subject to certain
anticipated exceptions in the Deposit Agreements, of any holders of Depositary
Receipts to surrender any Depositary Receipt with instructions to deliver to the
holder the related Preferred Shares and all money and other property, if any,
represented thereby, except in order to comply with law. Every holder of an
outstanding Depositary Receipt at the time any such amendment becomes effective
shall be deemed, by continuing to hold such Depositary Receipt, to consent and
agree to such amendment and to be bound by the applicable Deposit Agreement as
amended thereby.
 
     A Deposit Agreement will be permitted to be terminated by Parkway upon not
less than 30 days' prior written notice to the applicable Preferred Shares
Depositary if (i) such termination is necessary to preserve Parkway's status as
a REIT or (ii) a majority of each series of Preferred Shares affected by such
termination consents to such termination, whereupon such Preferred Shares
Depositary will be required to deliver or make available to each holder of
Depositary Receipts, upon surrender of the Depositary Receipts held by such
holder, such number of whole or fractional Preferred Shares as are represented
by the Depositary Shares evidenced by such Depositary Receipts together with any
other property held by such Preferred Shares Depositary with respect to such
Depositary Receipts. Parkway will agree that if a Deposit Agreement is
terminated to preserve Parkway's status as a REIT, then Parkway will use its
best efforts to list the Preferred Shares issued upon surrender of the related
Depositary Shares on a national securities exchange. In addition, a Deposit
Agreement will automatically terminate if (i) all outstanding Depositary Shares
thereunder shall have been redeemed; (ii) there shall have been a final
distribution in respect of the related Preferred Shares in connection with any
liquidation, dissolution or winding up of Parkway and such distribution shall
have been distributed to the holders of Depositary Receipts evidencing the
Depositary Shares representing such Preferred Shares; or (iii) each share of the
related Preferred Shares shall have been converted into stock of Parkway not so
represented by Depositary Shares.
 
CHARGES OF A PREFERRED SHARES DEPOSITARY
 
     Parkway will pay all transfer and other taxes and governmental charges
arising solely from the existence of a Deposit Agreement. In addition, Parkway
will pay the fees and expenses of a Preferred Shares Depositary in connection
with the performance of its duties under a Deposit Agreement. However, holders
of Depositary Receipts will pay the fees and expenses of a Preferred Shares
Depositary for any duties requested by such
                                       22
<PAGE>   35
 
holders to be performed which are outside of those expressly provided for in the
applicable Deposit Agreement.
 
RESIGNATION AND REMOVAL OF DEPOSITARY
 
     A Preferred Shares Depositary will be permitted to resign at any time by
delivering to Parkway notice of its election to do so, and Parkway will be
permitted at any time to remove a Preferred Shares Depositary, any such
resignation or removal to take effect upon the appointment of a successor
Preferred Shares Depositary. A successor Preferred Shares Depositary will be
required to be appointed within 60 days after delivery of the notice of
resignation or removal and will be required to be a bank or trust company having
its principal office in the United States and having a combined capital and
surplus of at least $50,000,000.
 
MISCELLANEOUS
 
     A Preferred Shares Depositary will be required to forward to holders of
Depositary Receipts any reports and communications from Parkway which are
received by such Preferred Shares Depositary with respect to the related
Preferred Shares.
 
     Neither a Preferred Shares Depositary nor Parkway will be liable if it is
prevented from or delayed in, by law or any circumstances beyond its control,
performing its obligations under a Deposit Agreement. The obligations of Parkway
and Preferred Shares Depositary under a Deposit Agreement will be limited to
performing their duties thereunder in good faith and without negligence (in the
case of any action or inaction in the voting of Preferred Shares represented by
the applicable Depositary Shares), gross negligence or willful misconduct, and
neither Parkway nor any applicable Preferred Shares Depositary will be obligated
to prosecute or defend any legal proceeding in respect of any Depositary
Receipts, Depositary Shares or Preferred Shares represented thereby unless
satisfactory indemnity is furnished. Parkway and any Preferred Shares Depositary
will be permitted to rely on written advice of counsel or accountants, or
information provided by persons presenting Preferred Shares represented thereby
for deposit, holders of Depositary Receipts or other persons believed in good
faith to be competent to give such information, and on documents believed in
good faith to be genuine and signed by a proper party.
 
     In the event a Preferred Shares Depositary shall receive conflicting
claims, requests or instructions from any holders of Depositary Receipts, on the
one hand, and Parkway on the other hand, such Preferred Shares Depositary shall
be entitled to act on such claims, requests or instructions received from
Parkway.
 
                          DESCRIPTION OF COMMON SHARES
 
GENERAL
 
     Parkway is authorized to issue up to 69,424,000 Common Shares. As of
January 6, 1997, there were 4,257,534 Common Shares outstanding and 280,648
Common Shares reserved for issuance upon the exercise of options granted under
Parkway's 1991 Directors Stock Option Plan and Parkway's 1994 Stock Option Plan.
All of the issued and outstanding Common Shares are fully paid and
non-assessable and have equal voting, distribution and liquidation rights.
Common Shares are not subject to call or redemption; provided, however, if the
Parkway Board of Directors determines that the direct or indirect ownership of
Common Shares has or may become concentrated to an extent which threatens
Parkway's status as a REIT, the Board of Directors may call for the redemption
of a number of Common Shares.
 
     The holders of Common Shares are entitled to one vote per share on all
matters to be voted upon by the stockholders. The holders of Common Shares have
no cumulative voting rights. Additionally, subject to the rights of holders of
Preferred Shares, holders of Common Shares are entitled to receive such
dividends as may be declared from time to time by the directors out of funds
legally available therefor.
 
     The Common Shares currently outstanding are listed for trading on the NYSE
under the symbol "PKY." Parkway will apply to the NYSE to list the additional
Common Shares to be sold pursuant to any Prospectus Supplement, and Parkway
anticipates that such shares will be so listed.
                                       23
<PAGE>   36
 
     Under Maryland law, stockholders are generally not liable for Parkway's
debts or obligations. If Parkway is liquidated, subject to the right of any
holders of Preferred Shares, if any, to receive preferential distributions, each
outstanding Common Share will be entitled to participate pro rata in the assets
remaining after payment of, or adequate provision for, all known debts and
liabilities of Parkway.
 
PROVISIONS OF PARKWAY'S CHARTER AND BYLAWS
 
     Parkway's Charter provide that the number of directors will be ten, which
number may be increased or decreased pursuant to Parkway's Bylaws. All ten
positions on the Board of Directors are filled by the vote of the stockholders
at the annual meeting. Stockholders do not have cumulative voting rights in the
election of directors. Stockholders are entitled to one vote for each Common
Share held by them.
 
OTHER MATTERS
 
     The transfer agent and registrar for the Common Shares is KeyCorp
Stockholder Services, Inc., Cleveland, Ohio.
 
RESTRICTIONS ON TRANSFER
 
     Ownership Limits.  For Parkway to qualify as a REIT under the Code, no more
than 50% in value of its outstanding Common Shares may be owned, actually and
constructively under the applicable attribution provisions of the Code, by five
or fewer individuals (as defined in the Code to include certain entities) during
the last half of a taxable year (other than the first year) or during a
proportionate part of a shorter taxable year. The Common Shares must also be
beneficially owned by 100 or more persons during at least 335 days of a taxable
year (other than the first year) or during a proportionate part of a shorter
taxable year. Because Parkway intends to elect to be treated as a REIT, the
Charter contains restrictions on the acquisition of Common Shares intended to
ensure compliance with these requirements.
 
     Pursuant to the provisions of the Charter, if a transfer of stock occurs
whereby any person would own, beneficially or constructively, in excess of 9.8
percent (in value or in number, whichever is more restrictive) of the
outstanding capital stock of Parkway (excluding Excess Shares), then such amount
in excess of the 9.8 percent limit shall automatically be converted into shares
of a separate class of stock, the excess stock, par value $0.001 per share, of
Parkway (the "Excess Shares"), and any such transfer will be void ab initio.
However, such restrictions will not prevent the settlement of a transaction
entered into through the facilities of any interdealer quotation system or
national securities exchange upon which shares of capital stock of Parkway are
traded, provided that certain transactions may be settled by providing Excess
Shares. Although holders of Excess Shares have no dividend or voting rights,
such holders do have certain rights in the event of any liquidation, dissolution
or winding up of the corporation. The Charter further provides that the Excess
Shares will be held by Parkway as trustee for the person or persons in whose
hands the shares would not be Excess Shares and certain price-related
restrictions are satisfied. These provisions are designed to enable Parkway to
meet the share ownership requirements applicable to REITs under the Code, but
may also have an anti-takeover effect. Parkway currently has 30,000,000 Excess
Shares authorized pursuant to its Charter.
 
     Each stockholder shall, upon request by Parkway, furnish such information
that Parkway may reasonably request in order to determine Parkway's status as a
REIT, to comply with the requirements of any taxing authority or governmental
agency or to determine any such compliance.
 
     The foregoing ownership limitations may have the effect of precluding
acquisition of control of Parkway without the consent of the Board of Directors.
 
     Special Voting Requirements for Certain Business Combinations.  Pursuant to
Maryland law, Parkway is governed by special procedures that apply to certain
business combinations between a corporation and interested stockholders. The
purpose of such provisions is to protect the corporation and its stockholders
against hostile takeovers by requiring that certain criteria are satisfied.
These criteria include prior approval by the board of directors, prior approval
by a majority or supermajority vote of disinterested stockholders and
requirements that a "fair price" be paid to the disinterested stockholders.
 
                                       24
<PAGE>   37
 
     Maryland law provides that a Maryland corporation may not engage in any
"business combination" with any "interested stockholder." An "interested
stockholder" is defined, in essence, as any person owning beneficially, directly
or indirectly, ten percent or more of the outstanding voting stock of a Maryland
corporation. Unless an exemption applies, Parkway may not engage in any business
combination with an interested stockholder for a period of five years after the
interested stockholder became an interested stockholder, and thereafter may not
engage in a business combination unless it is recommended by the board of
directors and approved by the affirmative vote of at least (i) eighty percent of
the votes entitled to be cast by the holders of all outstanding voting stock of
Parkway, voting together as a single voting group and (ii) two-thirds of the
votes entitled to be cast by all holders of outstanding shares of voting stock
other than voting stock held by the interested stockholder. The voting
requirements do not apply at any time to business combinations with an
interested stockholder or its affiliates if approved by the board of directors
of the corporation prior to the time the interested stockholder first became an
interested stockholder. Additionally, if the business combination involves the
receipt of consideration by the stockholders in exchange for the corporation's
stock, the voting requirements do not apply if certain "fair price" conditions
are met.
 
     Control Share Acquisitions.  Maryland law provides for the elimination of
the voting rights of shares held by any person who makes a "control share
acquisition" except to the extent that such acquisition is exempt or is approved
by at least two-thirds of all votes entitled to be cast on the matter, excluding
shares of capital stock owned by the acquirer or by officers or directors who
are employees of the corporation whose shares were acquired. A "control share
acquisition" is the direct or indirect acquisition by any person of ownership
of, or the power to direct the exercise of voting power with respect to, shares
of voting stock ("control shares") that would, if aggregated with all other
voting stock owned by such person, entitle such person to exercise voting power
in electing directors within one of the following ranges of voting power: (i)
one-fifth or more but less than one-third; (ii) one-third or more but less than
a majority; or (iii) a majority or more of voting power.
 
     A person who has made or proposes to make a control share acquisition, upon
the satisfaction of certain conditions (including an undertaking to pay
expenses), may compel the board of directors to call a special meeting of
stockholders to be held within 50 days of demand to consider the voting rights
of the shares. If no request for a meeting is made, the corporation may itself
present the question at any stockholders meeting. If voting rights are not
approved at the meeting or if the acquiring person does not deliver an acquiring
person statement as permitted by the statute, then, subject to certain
conditions and limitations, the corporation may redeem any or all of the control
shares (except those for which voting rights have previously been approved) for
fair value determined, without regard to voting rights, as of the date of the
last control share acquisition or as of the date of any meeting of stockholders
at which the voting rights of such shares are considered and not approved.
 
     If voting rights for control shares are approved at a stockholders meeting
and the acquirer becomes entitled to vote a majority of the shares entitled to
vote, all other stockholders may exercise appraisal rights. The fair value of
the stock as determined for purposes of such appraisal rights may not be less
than the highest price per share paid in the control share acquisition, and
certain limitations and restrictions otherwise applicable to the exercise of
dissenters' rights do not apply in the context of a control share acquisition.
The control share acquisition statute does not apply to stock acquired in a
merger, consolidation or stock exchange if the corporation is a party to the
transaction.
 
     Supermajority Votes.  The Charter provides that (i) no term or provision of
the Charter may be added, amended or repealed in any respect which, in the
determination of the Board of Directors, cause Parkway not to qualify as a REIT
under the Code; (ii) the sections of the Charter concerning the removal of
directors, amendment of the Bylaws, the indemnification of agents and limitation
of liability of directors and officers and the section concerning special
stockholder vote requirements shall not be amended or repealed; and (iii) no
provision imposing cumulative voting in the election of directors may be added
to the Charter, except, in addition to any vote required by the terms of then
outstanding Preferred Shares, upon the affirmative vote of the holders of not
less than eighty percent of all votes entitled to be cast on the matter.
 
     Stockholders Rights Agreement.  Stockholders, pursuant to a Rights
Agreement, have the right to purchase Common Shares at a price of $40.00 per
share (as adjusted for the three-for-two stock split effected

April 30, 1996), subject to adjustment, on a Distribution Date which will occur
on the earliest of (i) the date of Parkway's public announcement that a person
or group of affiliated or associated persons (an "Acquiring Person") has
acquired, or obtained the right to acquire, beneficial ownership of 20% or more
of the outstanding Common Shares (the "Stock Acquisition Date"); (ii) 10 days
following the commencement of a tender offer or exchange offer that would result
in a person or group beneficially owning 30% or more of the outstanding Common
Shares; or (iii) 10 days after the Board of Directors shall declare any person
to be an "Adverse Person," as defined in the Rights Agreement. The Rights are
not exercisable until the Distribution Date and expire at the close of business
on September 6, 2005, unless earlier redeemed by Parkway.
 
     In the event any person becomes an Acquiring Person, each holder of a Right
will have the right to receive, upon exercise of the Right and payment of the
purchase price, Common Shares (or, if sufficient Common Shares are unavailable
and subject to certain limitations, cash, property or other securities of
Parkway) having a value equal to two times the purchase price of the Right
(referred to as the "Subscription Right"). The Subscription Right is exercisable
during the 60-day period following the later of the Stock Acquisition Date or
the effective date of a registration statement covering the Common Shares (or
other securities, if applicable) subject to the Subscription Right (referred to
as the "Subscription Period"). Notwithstanding any of the foregoing, all Rights
that are, or (under certain circumstances specified in the Rights Agreement)
were, beneficially owned by any Acquiring Person will be null and void.
 
     In the event that, at any time following the Stock Acquisition Date, (i)
Parkway engages in a merger or other business combination transaction or (ii)
50% or more of Parkway's assets or earning power is sold or transferred, each
holder of a Right (except Rights which previously have been voided pursuant to
the Rights Agreement) shall thereafter have the right to receive, upon exercise,
common stock of the acquiring company having a value equal to two times the
purchase price of the Right.
 
     The purchase price payable, and the number of Common Shares (or the number
and kind of other securities or property, as the case may be) issuable upon
exercise of the Rights are subject to adjustment from time to time to prevent
dilution.
 
                       FEDERAL INCOME TAX CONSIDERATIONS
 
INTRODUCTORY NOTES
 
     The following discussion summarizes certain Federal income tax
considerations that may be relevant to a prospective stockholder of Parkway.
This discussion is based on current law. The discussion is not exhaustive of all
possible tax considerations and does not discuss any state, local or foreign tax
considerations. It also does not discuss all of the aspects of Federal income
taxation that may be relevant to a prospective stockholder in light of his or
her particular circumstances or to certain types of stockholders (including
insurance companies, tax-exempt entities, financial institutions or
broker-dealers, foreign corporations and persons who are not citizens or
residents of the United States) who are subject to special treatment under the
Federal income tax laws.
 
     EACH PROSPECTIVE PURCHASER IS ADVISED TO CONSULT WITH HIS OR HER OWN TAX
ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES TO HIM OR HER OF THE PURCHASE,
OWNERSHIP AND SALE OF SECURITIES IN AN ENTITY ELECTING TO BE TAXED AS A REIT,
INCLUDING THE FEDERAL, STATE, LOCAL, FOREIGN, AND OTHER TAX CONSEQUENCES OF SUCH
PURCHASE, OWNERSHIP, SALE AND ELECTION AND OF POTENTIAL CHANGES IN APPLICABLE
TAX LAWS.
 
TAXATION OF THE COMPANY
 
     General.  Parkway expects that it will be organized and will operate in a
manner so as to qualify to be taxed as a REIT under Sections 856 through 860 of
the Code commencing with its taxable year ending December 31, 1997. Although
management of Parkway believes that Parkway is organized and operating in a
manner that permits it to qualify as a REIT, and intends to continue to operate
in such a manner in the future,
 
                                       26
<PAGE>   39
 
no assurance can be given that Parkway will operate in a manner so as to qualify
or remain qualified as a REIT. See "-- Failure to Qualify" below. Parkway's
qualification and taxation as a REIT depends upon its ability to meet on a
continuing basis, through actual annual operating results, distribution levels
and diversity of stock ownership, the various qualification tests and
organizational requirements imposed under the Code, as discussed below.
 
     Jaeckle Fleischmann & Mugel, LLP has acted as counsel to Parkway in
connection with Parkway's election to be taxed as a REIT. In the opinion of
Jaeckle, Fleischmann & Mugel, LLP, assuming that the elections and other
procedural steps described in the following discussion of "Requirements for
Qualification" are completed by Parkway in a timely fashion, Parkway's
organization and proposed method of operation will enable it to qualify to be
taxed as a REIT under the Code commencing with Parkway's taxable year ending
December 31, 1997, and for its future taxable years. Investors should be aware,
however, that opinions of counsel are not binding upon the Service or any court.
It must be emphasized that the opinion is based on various assumptions and is
conditioned upon certain representations made by Parkway as to factual matters,
including representations regarding the nature of Parkway's properties and the
future conduct of its business. Such factual assumptions and representations are
described below in this discussion of "Federal Income Tax Considerations" and
are set out in the federal income tax opinion that will be delivered by Jaeckle
Fleischmann & Mugel, LLP at the closing of each offering contemplated by this
Prospectus. Moreover, such qualification and taxation as a REIT depends upon
Parkway's ability to meet on a continuing basis, through actual annual operating
results, distribution levels and share ownership, the various qualification
tests imposed under the Code discussed below. Jaeckle Fleischmann & Mugel, LLP
will not review Parkway's compliance with those tests on a continuing basis.
Accordingly, no assurance can be given that the actual results of Parkway's
operations for any particular taxable year will satisfy such requirements. For a
discussion of the tax consequences of failure to qualify as a REIT, see "Failure
to Qualify" below.
 
     The following is a general summary of the Code provisions that govern the
Federal income tax treatment of a REIT and its stockholders. These provisions of
the Code are highly technical and complex. This summary is qualified in its
entirety by the applicable Code provisions, the regulations promulgated
thereunder ("Treasury Regulations"), and administrative and judicial
interpretations thereof.
 
     If Parkway qualifies for taxation as a REIT and distributes to its
stockholders at least 95% of its REIT taxable income, it generally will not be
subject to Federal corporate income taxes on the portion of its ordinary or
capital gain income that it currently distributes to stockholders. This
treatment substantially eliminates the "double taxation" (at the corporate and
stockholder levels) that generally results from investment in a corporation.
Even if Parkway qualifies as a REIT, it will be subject to Federal income tax in
the following circumstances. First, Parkway will be taxed at regular corporate
rates on any undistributed taxable income, including undistributed net capital
gains. Second, under certain circumstances, Parkway may be subject to the
"alternative minimum tax" on its items of tax preference. Third, if Parkway has
(i) net income from the sale or other disposition of "foreclosure property"
(which is, in general, property acquired by foreclosure or otherwise on default
of a loan secured by the property) which is held primarily for sale to customers
in the ordinary course of business or (ii) other non-qualifying income from
foreclosure property, it will be subject to tax at the highest corporate rate on
such income. Fourth, if Parkway has net income from prohibited transactions
(which are, in general, certain sales or other dispositions of property (other
than foreclosure property) held primarily for sale to customers in the ordinary
course of business), such income will be subject to a 100% tax. Fifth, if
Parkway should fail to satisfy the 75% gross income test or the 95% gross income
test (as discussed below), and has nonetheless maintained its qualification as a
REIT because certain other requirements have been met, it will be subject to a
100% tax on the net income attributable to the greater of the amount by which it
fails the 75% or 95% test, multiplied by a fraction intended to reflect its
profitability. Sixth, if Parkway should fail to distribute during each calendar
year at least the sum of (i) 85% of its REIT ordinary income for such year; (ii)
95% of its REIT capital gain net income for such year; and (iii) any
undistributed taxable income from prior years, Parkway would be subject to a 4%
excise tax on the excess of such required distribution over the amounts actually
distributed. Seventh, Parkway will be subject to tax at the highest corporate
rates on built-in gains recognized within a 10-year period of its election to be
taxable as a REIT on assets it formerly held while it was a C corporation. In
addition, if Parkway acquires any additional asset from a C corporation (i.e., a
corporation generally subject to full corporate level tax) in a transaction in
 
                                       27
<PAGE>   40
 
which the basis of the asset in Parkway's hands is determined by reference to
the basis of the asset (or any other property) in the hands of the C
corporation, and Parkway recognizes gain on the disposition of such asset during
the 10-year period beginning on the date on which such asset was acquired by it,
then, to the extent of such asset's built-in gain (the excess of the fair market
value of such property at the time of acquisition by Parkway over the adjusted
basis of such property at such time), such gain will be subject to tax at the
highest regular corporate rate applicable (as provided in IRS regulations that
have not yet been promulgated).
 
     Requirements for Qualification.  The Code defines a REIT as a corporation,
trust or association (i) which is managed by one or more trustees or directors;
(ii) the beneficial ownership of which is evidenced by transferable shares or by
transferable certificates of beneficial interest; (iii) which would be taxable
as a domestic corporation, but for Sections 856 through 860 of the Code; (iv)
which is neither a financial institution nor an insurance company subject to
certain provisions of the Code; (v) the beneficial ownership of which is held by
100 or more persons; (vi) during the last half of each taxable year not more
than 50% in value of the outstanding stock of which is owned, directly or
indirectly, by five or fewer individuals (as defined in the Code to include
certain entities); and (vii) which meets certain other tests, described below,
regarding the nature of its income and assets. The Code provides that conditions
(i) through (iv), inclusive, must be met during the entire taxable year and that
condition (v) must be met during at least 335 days of a taxable year of 12
months, or during a proportionate part of a taxable year of less than 12 months.
Conditions (v) and (vi) will not apply until after the first taxable year for
which an election is made to be taxed as a REIT. Parkway satisfies the
requirements (i) through (iv) as of January 1, 1997. Parkway's Charter contains
restrictions regarding the transfer of its shares that are intended to assist it
in satisfying the share ownership requirements described in (v) and (vi) above.
 
     Parkway currently has 14 wholly-owned subsidiaries and may have additional
subsidiaries in the future. Code Section 856(i) provides that a corporation that
is a "qualified REIT subsidiary" shall not be treated as a separate corporation
and all assets, liabilities and items of income, deduction and credit of a
"qualified REIT subsidiary" shall be treated as assets, liabilities and items of
income, deduction and credit of the REIT. A "qualified REIT subsidiary" is a
corporation, all of the capital stock of which has been held by the REIT at all
times during the period such corporation was in existence. The Service currently
takes the position for private ruling purposes that a 100% owned subsidiary of
an entity electing REIT status will be classified as a "qualified REIT
subsidiary" even though the REIT did not own 100% of the subsidiary's
outstanding stock throughout the subsidiary's existence. The Service has treated
the subsidiary as liquidated immediately prior to the date of REIT election and
subsequently incorporated by the REIT. Thus, Jaeckle, Fleischman & Mugel, LLP,
counsel to Parkway, believes that in applying the requirements described herein,
the current subsidiaries of Parkway will be "qualified REIT subsidiaries". As
such, the separate existence of such subsidiaries will be ignored for federal
income tax purposes, and all assets, liabilities and items of income, deduction
and credit of such subsidiaries will be treated as assets, liabilities and items
of income, deduction and credit of Parkway. The qualified REIT subsidiaries,
therefore, will not be subject to federal corporate income taxation, although
they may be subject to state and local taxation.
 
     In the case of a REIT that is a partner in a partnership, Treasury
Regulations provide that the REIT will be deemed to own its proportionate share
of the assets of the partnership and will be deemed to be entitled to the gross
income of the partnership attributable to such share. In addition, the assets
and gross income of the partnership will retain the same character in the hands
of the REIT for purposes of Section 856 of the Code, including satisfying the
gross income and asset tests described below. Thus, Parkway's proportionate
share of the assets, liabilities and items of income of any partnership owned
and the noncorporate subsidiaries of any such partnership will be treated as
assets, liabilities and items of income of Parkway for purposes of applying the
requirements described herein.
 
     A corporation may not elect to become a REIT unless its taxable year is the
calendar year. Parkway's taxable year currently ends on June 30. Parkway will
change its taxable year to the calendar year effective for the short period from
July 1, 1996 to December 31, 1996, in order to meet this requirement. In
addition, pursuant to applicable Treasury Regulations, in order to be able to
elect to be taxed as a REIT, Parkway must maintain certain records and request
on an annual basis certain information from its stockholders designed to
disclose the actual ownership of its outstanding shares. Parkway intends to
comply with such requirements.
                                       28

     Earnings and Profits Calculation.  In order to elect REIT status, Parkway
cannot have earnings and profits which have been generated during years in which
Parkway was not qualified as a REIT. For this purpose, under the Code, earnings
and profits of companies which have been acquired by Parkway and the earnings
and profits of any of Parkway's subsidiaries are included in calculating
Parkway's earnings and profits account. The determination of the earnings and
profits account of a company is a highly technical and complex undertaking.
Parkway's predecessor, The Parkway Company, was organized in 1971 and over the
years has acquired several companies. In calculating the earnings and profits
account, studies have been undertaken of not only Parkway's earnings and profits
history, but also the history of all acquired companies. Based on these studies,
and on its estimate of earnings and profits for the period ending December 31,
1996, Parkway believes that it did not have any positive accumulated earnings
and profits on January 1, 1997, the effective date of its REIT election. In the
event its earnings and profits account was positive, Parkway will be required to
distribute dividends sufficient to reduce that account to zero prior to December
31, 1997. There is no assurance that the Service will not challenge Parkway's
calculation of earnings and profits. If such a challenge were successful, or if
Parkway otherwise retains any such non-REIT earnings and profits at the close of
its taxable year ending December 31, 1997, it will not qualify for taxation as a
REIT.
 
     Income Tests.  In order to maintain qualification as a REIT, three separate
percentage tests relating to the source of its gross income must be satisfied
annually. First, at least 75% of the REIT's gross income (excluding gross income
from prohibited transactions) for each taxable year must be derived directly or
indirectly from investments relating to real property or mortgages on real
property (including "rents from real property" and, in certain circumstances,
interest) or from certain types of temporary investments. Second, at least 95%
of the REIT's gross income (excluding gross income from prohibited transactions)
for each taxable year must be derived from such real property investments
described above, and from dividends, interest and gain from the sale or
disposition of stock or securities, or from any combination of the foregoing.
Third, gain from the sale or other disposition of (i) stock or securities held
for less than one year; (ii) prohibited transactions; and (iii) certain real
property held for less than four years (apart from involuntary conversions and
sales of foreclosure property) must represent less than 30% of the REIT's gross
income (including gross income from prohibited transactions) for each taxable
year.
 
     Rents received by Parkway will qualify as "rents from real property" in
satisfying the above gross income tests only if several conditions are met.
First, the amount of rent must not be based in whole or in part on the income or
profits of any person. However, amounts received or accrued generally will not
be excluded from "rents from real property" solely by reason of being based on a
fixed percentage or percentages of receipts or sales. Second, rents received
from a tenant will not qualify as "rents from real property" if Parkway, or a
direct or indirect owner of 10% or more of Parkway, directly or constructively
owns 10% or more of such tenant (a "Related Party Tenant"). Third, if rent
attributable to personal property that is leased in connection with a lease of
real property is greater than 15% of the total rent received under the lease,
then the portion of rent attributable to such personal property will not qualify
as "rents from real property." Finally, for rents received to qualify as "rents
from real property," Parkway generally must not operate or manage the property
or furnish or render services to tenants, other than through an "independent
contractor" who is adequately compensated and from whom Parkway derives no
revenue. The "independent contractor" requirement, however, does not apply to
the extent the services provided by Parkway are "usually or customarily
rendered" in connection with the rental of space for occupancy only and are not
otherwise considered "rendered to the occupant." Parkway believes that all
services that are provided to its tenants will be considered "usually or
customarily" rendered in connection with the rental of comparable properties.
Further, any noncustomary services will be provided only through qualifying
independent contractors. Parkway believes that its assets will in major part
give rise to rental income qualifying under the 75% and 95% gross income tests.
Parkway will receive some income that is not qualifying income for purposes of
the 75% and 95% gross income tests. Such income includes certain management and
brokerage fee income. The aggregate amount of such fees and other non-qualifying
income in any taxable year is not expected to cause Parkway to fail to qualify
under the 75% and 95% gross income tests.
 
     If Parkway fails to satisfy one or both of the 75% or 95% gross income
tests for any taxable year, it may nevertheless qualify as a REIT for such year
if it is entitled to relief under certain provisions of the Code. These relief
provisions generally will be available if its failure to meet such tests was due
to reasonable cause
                                       29
<PAGE>   42
 
and not due to willful neglect, Parkway attaches a schedule of the sources of
its income to its federal income tax return for such years, and any incorrect
information on the schedules was not due to fraud with intent to evade tax. It
is not possible, however, to state whether in all circumstances Parkway would be
entitled to the benefit of these relief provisions. As discussed above in
"General," even if these relief provisions were to apply, a tax would be imposed
with respect to the excess net income.
 
     Asset Tests.  At the close of each quarter of its taxable year, Parkway
must also satisfy three tests relating to the nature of its assets. First, at
least 75% of the value of Parkway's total assets must be represented by certain
real estate assets (including temporary investments in stock or debt instruments
purchased with the proceeds of a stock or debt offering of Parkway and held
during the one year period from Parkway's receipt of capital in connection with
said offering), cash, cash items and government securities. Second, not more
than 25% of Parkway's total assets may be represented by securities other than
those in the 75% asset class. Third, of the investments included in the 25%
asset class, the value of any one issuer's securities owned by Parkway may not
exceed 5% of the value of Parkway's total assets, and Parkway may not own more
than 10% of any one issuer's outstanding voting securities (excluding securities
of a qualified REIT subsidiary or another REIT). Parkway believes that the
nature of its assets which it owned on January 1, 1997 will permit it to meet
the asset tests outlined above.
 
     If Parkway should fail to satisfy the asset tests at the end of a calendar
quarter, such a failure would not cause it to lose its REIT status if (i) it
satisfied the asset tests at the close of the preceding calendar quarter and
(ii) the discrepancy between the value of Parkway's assets and the asset tests
either did not exist immediately after the acquisition of any particular asset
or was not wholly or partly caused by such an acquisition (e.g., the discrepancy
arose from changes in the market values of its assets). If the conditions
described in clause (ii) of the preceding sentence were not satisfied, Parkway
still could avoid disqualification by eliminating any discrepancy within 30 days
after the close of the calendar quarter in which it arose.
 
     Annual Distribution Requirements.  Parkway, in order to qualify as a REIT,
is required to distribute dividends (other than capital gain dividends) to its
shareholders in an amount at least equal to (i) the sum of (a) 95% of its "REIT
taxable income" (computed without regard to the dividends paid deduction and its
net capital gain) and (b) 95% of the net income (after tax), if any, from
foreclosure property, minus (ii) the sum of certain items of noncash income.
Such distributions must be paid in the taxable year to which they relate, or in
the following taxable year if declared before Parkway timely files its tax
return for such year and if paid on or before the first regular dividend payment
after such declaration. To the extent that Parkway does not distribute all of
its net capital gain or distributes at least 95%, but less than 100%, of its
"REIT taxable income," as adjusted, it will be subject to tax on the
nondistributed amount at regular capital gains and ordinary corporate tax rates.
Furthermore, if Parkway should fail to distribute during each calendar year at
least the sum of (i) 85% of its REIT ordinary income for such year; (ii) 95% of
its REIT capital gain income for such year; and (iii) any undistributed taxable
income from prior periods, it will be subject to a 4% excise tax on the excess
of such required distribution over the amounts actually distributed.
 
     Parkway intends to make timely distributions sufficient to satisfy the
annual distribution requirements. It is possible, however, that Parkway, from
time to time, may not have sufficient cash or liquid assets to meet the
distribution requirements due to timing differences between the actual receipt
of income and actual payment of deductible expenses and the inclusion of such
income and deduction of such expenses in arriving at Parkway's REIT taxable
income, or if the amount of nondeductible expenses such as principal
amortization or capital expenditures exceed the amount of noncash deductions. In
the event that such timing differences occur, in order to meet the distribution
requirements, Parkway may arrange for short-term, or possible long-term,
borrowing to permit the payment of required dividends. If the amount of
nondeductible expenses exceeds noncash deductions, Parkway may refinance its
indebtedness to reduce principal payments and borrow funds for capital
expenditures.
 
     Under certain circumstances, Parkway may be able to rectify a failure to
meet the distribution requirement for a year by paying "deficiency dividends" to
stockholders in a later year that may be included in Parkway's deduction for
dividends paid for the earlier year. Thus, Parkway may be able to avoid being
taxed on amounts distributed as deficiency dividends; however, it will be
required to pay interest to the Service based upon the amount of any deduction
taken for deficiency dividends.
 
                                       30
<PAGE>   43
 
     Failure to Qualify.  If Parkway fails to qualify for taxation as a REIT in
any taxable year and no relief provisions apply, Parkway will be subject to tax
(including any applicable alternative minimum tax) on its taxable income at
regular corporate rates. Distributions to stockholders in any year in which
Parkway fails to qualify will not be deductible by it, nor will such
distributions be required to be made. In such event, to the extent of current
and accumulated earnings and profits, all distributions to stockholders will be
taxable as ordinary income, and, subject to certain limitations in the Code,
corporate distributees may be eligible for the dividends received deduction.
Unless entitled to relief under specific statutory provisions, Parkway also will
be disqualified from taxation as a REIT for the four taxable years following the
year during which qualification was lost. It is not possible to state whether in
all circumstances Parkway would be entitled to such statutory relief.
 
TAXATION OF STOCKHOLDERS
 
     Taxation of Taxable Domestic Stockholders.  As long as Parkway qualifies as
a REIT, distributions made to its taxable domestic stockholders out of current
or accumulated earnings and profits (and not designated as capital gain
dividends) will be taken into account by them as ordinary income, and corporate
stockholders will not be eligible for the dividends received deduction as to
such amounts. Domestic stockholders generally are stockholders who are (i)
citizens or residents of the United States; (ii) corporations, partnerships or
other entities created or organized in or under the laws of the United States or
any political subdivision thereof; or (iii) estates or trusts the income of
which is subject to United States federal income taxation regardless of its
source. Distributions that are designated as capital gain dividends will be
taxed as long-term capital gains (to the extent they do not exceed Parkway's
actual net capital gain for the taxable year) without regard to the period for
which the stockholder has held his or her shares. However, corporate
stockholders may be required to treat up to 20% of certain capital gain
dividends as ordinary income. Distributions in excess of current and accumulated
earnings and profits will not be taxable to a shareholder to the extent that
they do not exceed the adjusted basis of the stockholder's shares, but rather
will reduce the adjusted basis of such shares. To the extent that such
distributions exceed the adjusted basis of a stockholder's shares, they will be
included in income as long-term capital gain (or short-term capital gain if the
shares have been held for one year or less), assuming the shares are a capital
asset in the hands of the stockholders. In addition, any dividend declared by
Parkway in October, November or December of any year payable to a stockholder of
record on a specific date in any such month shall be treated as both paid by
Parkway and received by the stockholder on December 31 of such year, provided
that the dividend is actually paid by Parkway during January of the following
calendar year. Stockholders may not include in their individual income tax
returns any net operating losses or capital losses of Parkway.
 
     In general, any gain or loss realized upon a taxable disposition of shares
by a stockholder who is not a dealer in securities will be treated as a long
term capital gain or loss if the shares have been held for more than one year
and otherwise a short term capital gain or loss. However, any loss upon a sale
or exchange of shares by a stockholder who has held such shares for six months
or less (after applying certain holding period rules) will be treated as
long-term capital loss to the extent of distributions from Parkway required to
be treated by such stockholder as long-term capital gain.
 
     Backup Withholding.  Parkway will report to its domestic stockholders and
the IRS the amount of dividends paid during each calendar year, and the amount
of tax withheld, if any, with respect thereto. Under the backup withholding
rules, a stockholder may be subject to backup withholding at the rate of 31%
with respect to dividends paid unless such holder (i) is a corporation or comes
within certain other exempt categories and, when required, demonstrates this
fact, or (ii) provides a taxpayer identification number, certifies as to no loss
of exemption from backup withholding, and otherwise complies with applicable
requirements of the backup withholding rules. A stockholder who does not provide
Parkway with its correct taxpayer identification number may also be subject to
penalties imposed by the Service. Any amount paid as backup withholding will be
creditable against the stockholder's income tax liability. In addition, Parkway
may be required to withhold a portion of capital gain distributions made to any
stockholders who fail to certify their non-foreign status to Parkway.
 
                                       31
<PAGE>   44
 
     Taxation of Foreign Stockholders and Tax-Exempt Stockholders.  The rules
governing U.S. Federal income taxation of nonresident alien individuals, foreign
corporations, foreign partnerships and other foreign stockholders as well as
U.S. tax-exempt stockholders are complex, and no attempt will be made herein to
review these rules. Prospective stockholders who fall within these categories
should consult with their own tax advisors to determine the impact of U.S.
Federal, state and local income tax laws with regard to an investment in the
shares, including any reporting requirements.
 
     State and Local Taxes.  Parkway and its stockholders may be subject to
state or local taxation in various state or local jurisdictions, including those
in which it or they transact business or reside (although stockholders who are
individuals generally should not be required to file state income tax returns
outside of their state of residence with respect to Parkway's operations and
distributions). The state and local tax treatment of Parkway and its
stockholders may not conform to the Federal income tax consequences discussed
above. Consequently, prospective stockholders should consult their own tax
advisors regarding the effect of state and local tax laws on an investment in
the Securities.
 
                              PLAN OF DISTRIBUTION
 
     Parkway may sell Securities to or through underwriters or dealers for
public offering and sale by or through them, and also may sell Securities
directly to other purchasers or agents or through any combination of these
methods of sale.
 
     The distribution of the Securities may be effected from time to time in one
or more transactions at a fixed price or prices, which may be changed, or at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices.
 
     In connection with the sale of Securities, underwriters may receive
compensation from Parkway or for purchasers of Securities, for whom they may act
as agents, in the form of discounts, concessions or commissions. Underwriters
may sell Securities to or through dealers, and such dealers may receive
compensation in the form of discounts, concessions or commissions from the
underwriters and/or commissions from the purchasers for whom they may act as
agents. Underwriters, dealers, and agents that participate in the distribution
of Securities may be deemed to be underwriters, and any discounts or commissions
they receive from Parkway and any profit on the resale of Securities they
realize may be deemed to be underwriting discounts and commissions, under the
Securities Act. Any such underwriter or agent will be identified, and any such
compensation received from Parkway will be described, in the applicable
Prospectus Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement, each
series of Securities will be a new issue with no established trading market,
other than the Common Shares which are listed on the NYSE. Any Common Shares
sold pursuant to a Prospectus Supplement will be listed on such exchange,
subject to official notice of issuance. Parkway may elect to list any series of
Debt Securities, Preferred Shares or Depositary Shares on an exchange, but is
not obligated to do so. It is possible that one or more underwriters may make a
market in a series of Securities, but will not be obligated to do so and may
discontinue any market making at any time without notice. Therefore, no
assurance can be given as to the liquidity of the trading market for the
Securities.
 
     Under agreements Parkway may enter into, underwriters, dealers and agents
who participate in the distribution of Securities may be entitled to
indemnification by Parkway against certain liabilities, including liabilities
under the Securities Act.
 
     Underwriters, dealers and agents may engage in transactions with, or
perform services for, or be customers of, Parkway in the ordinary course of
business.
 
     If so indicated in the applicable Prospectus Supplement, Parkway will
authorize underwriters or other persons acting as Parkway's agents to solicit
offers by certain institutions to purchase Securities from Parkway pursuant to
contracts providing for payment and delivery on a future date. Institutions with
which such contracts may be made include commercial and savings banks, insurance
companies, pension funds, investment companies, educational and charitable
institutions and others, but in all cases such institutions
 
                                       32

must be approved by Parkway. The obligations of any purchaser under any such
contract will be subject to the condition that the purchase of the Securities
shall not at the time of delivery be prohibited under the laws of the
jurisdiction to which such purchaser is subject. The underwriters and such other
agents will not have any responsibility in respect of the validity or
performance of such contracts.
