                         PROSPECTUS SUPPLEMENT SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information included elsewhere in this Prospectus Supplement and the
accompanying Prospectus and in documents incorporated herein or therein by
reference. Unless the context otherwise requires, all references in this
Prospectus Supplement to "Parkway" shall mean Parkway Properties, Inc. and its
subsidiaries on a consolidated basis and, as the context may require, their
predecessors. The per share information set forth herein gives retroactive
effect to a three-for-two stock split effected by Parkway on April 30, 1996.
Information in this Prospectus Supplement assumes that PaineWebber's
over-allotment option is not exercised. See "Underwriting."
 
                                  THE COMPANY
 
     Parkway is a self-administered real estate investment trust ("REIT")
specializing in the acquisition, ownership, management and leasing of office
properties in the Southeastern United States (primarily the states of Georgia,
Mississippi, North Carolina, Tennessee and Virginia) and Texas. At January 15,
1997, Parkway owned or had an interest in 18 office properties located in nine
states with an aggregate of approximately 2.15 million square feet of leasable
space.
 
     Parkway's management team of office property specialists has proven
capabilities in office property (i) acquisition, (ii) ownership, (iii)
management, (iv) leasing and (v) development. Management believes that these
capabilities should allow Parkway to continue to create office property value in
all phases of the real estate cycle. Furthermore, management also believes it
has a proven capability for acquiring other real estate companies at attractive
prices.
 
     Since July 1995, Parkway has pursued a strategy of aggressively acquiring
office properties. Parkway seeks to invest in markets characterized by positive
employment and population growth with attractive real estate market dynamics and
investment conditions. Parkway also seeks to invest in properties where
management can add value through direct asset and property management, a
"hands-on" operating strategy and Parkway's financial flexibility. Parkway
generally targets for acquisition office buildings ranging in size from 50,000
to 300,000 square feet which are occupied by a major tenant or tenants, have
current and projected occupancy levels in excess of 70% and provide adequate
parking to accommodate full occupancy. Concurrently with its recent office
property acquisitions, Parkway has strategically disposed of selected non-core
assets which no longer fit into its investment strategy and has redeployed the
proceeds from such dispositions into office property investments.
 
     Parkway's business objective is to maximize total return to stockholders
over time through increases in dividend distributions and share price
appreciation. Parkway has paid 41 consecutive quarterly cash distributions to
its stockholders. On December 6, 1996, Parkway announced a 79% increase in its
quarterly dividend from $0.14 per Common Share to $0.25 per Common Share. With
this increase, Parkway anticipates that its dividend payout ratio will
approximate 50% of its funds from operations ("FFO") for 1997. See "Recent
Developments -- Funds From Operations." This conservative dividend payout ratio
should allow Parkway to generate a significant amount of retained cash for use
in the acquisition of office properties.
 
     Parkway and its predecessors have been public companies engaged in the real
estate business since 1971. Parkway was incorporated under the laws of the State
of Maryland on May 17, 1996 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. As a result of the Merger,
Parkway succeeded to the business and operations of The Parkway Company.
Additionally, on August 22, 1996 the Common Shares became listed on the NYSE
under the symbol "PKY." Prior to this date, the Common Shares had been quoted on
the NASDAQ National Market under the symbol "PKWY."
 
     Parkway's principal office is located at 300 One Jackson Place, 188 East
Capitol Street, Jackson, Mississippi 39201-2195. Its telephone number is (601)
948-4091.

                                  RISK FACTORS
 
     An investment in the Common Shares involves various risks. Prospective
investors should carefully consider the following information in conjunction
with the other information contained or incorporated by reference in this
Prospectus Supplement and the accompanying Prospectus before making a decision
to purchase Common Shares.
 
RISKS RELATING TO PARKWAY'S ABILITY TO MANAGE RAPID GROWTH
 
     Parkway has acquired 10 office properties with approximately 1.31 million
square feet of leasable space since January 1, 1996 (the "Recent Acquisitions")
and is in the process of acquiring additional properties. Although Parkway
believes it has sufficient management depth to lead Parkway through this period
of rapid asset growth, there can be no assurance that Parkway will be able to
assimilate the Recent Acquisitions or any future acquisitions into its portfolio
without certain operating disruptions and unanticipated costs. Furthermore,
Parkway is evaluating many potential acquisitions and no assurance can be given
that Parkway will acquire all properties it evaluates. The evaluation process
involves costs which are non-recoverable. In addition, there can be no assurance
that properties which are acquired will perform in accordance with expectations
or that estimates for improvements to acquired properties to bring them up to
standards established for the market position intended for that property are
accurate.
 
TAX RISKS ASSOCIATED WITH REIT ELECTION
 
     Parkway intends to elect to qualify and is operating so as to qualify as a
REIT under the Internal Revenue Code of 1986, as amended (the "Code") commencing
with its taxable year beginning January 1, 1997. Although management of Parkway
believes that Parkway has been organized and will operate in such a manner, no
assurance can be given that Parkway 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 ownership restrictions on Parkway shares; (iv) having no
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, Parkway will be subject to federal
income tax (including any applicable alternative minimum tax) on its taxable
income at 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.
 
REAL ESTATE FINANCING RISKS
 
     No Limitation on Debt and Risk of Rising Interest Rates.  Although Parkway
intends to maintain what it believes to be conservative leverage (as of January
15, 1997 Parkway's ratio of debt to total market capitalization was
approximately 38%), Parkway's Articles of Incorporation, as amended (the
"Charter"), do not limit the amount of indebtedness that Parkway may incur. As
of January 15, 1997, Parkway has outstanding consolidated indebtedness of
approximately $70.2 million all of which is secured and approximately $62.8
million of which is fixed rate indebtedness. Furthermore, the Acquisition
Facility and Working
 
                                       S-5
<PAGE>   6
 
Capital Facility (each as defined below) have variable interest rates which may
rise if the level of interest rates in general increases, which would result in
an increase in Parkway's interest cost and adversely affect Parkway's net
income, FFO and ability to make expected distributions to its stockholders.
 
     Existing Debt Maturities and Refinancing Risks.  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. Parkway has a $45 million secured revolving credit facility (the
"Acquisition Facility") and a $10 million secured revolving credit facility (the
"Working Capital Facility"), both of which bear interest at variable rates equal
to LIBOR plus 2.35% (7.91% as of January 15, 1997). The Working Capital Facility
matures on June 30, 1997 and the Acquisition Facility matures on June 30, 1998.
As of the date of this Prospectus Supplement, there are no amounts outstanding
under the Acquisition Facility and approximately $7.4 million is outstanding
under the Working Capital Facility. Parkway intends to repay any amounts drawn
on such credit facilities with cash flow from operations, funds obtained from
the sale of securities, fixed rate financings secured by buildings purchased
with the Acquisition Facility or the proceeds from the sale of non-core assets.
There can be no assurance that securities market conditions will permit the sale
of securities, that fixed rate financing will be available or available on
acceptable terms, or that non-core assets will be sold to purchase office
properties or repay debt, and in the event variable rate debt remains
outstanding, any increase in interest rates could have a material adverse impact
on Parkway's financial results. Accordingly, there is a risk that existing
indebtedness will not be able to be refinanced or that the terms of such
refinancing will not be as favorable as the terms of the existing indebtedness.
 
     Risks of Foreclosure.  Nine of Parkway's office properties are security for
non-recourse mortgage indebtedness totaling approximately $62.8 million as of
January 15, 1997, one of Parkway's office properties is security for the
Acquisition Facility and a building owned by a partnership in which Parkway is a
50% partner is security for mortgage indebtedness of $912,000. Parkway's
non-recourse mortgage indebtedness has a weighted average remaining term of
approximately 14 years and a weighted average interest rate of 8.01% per annum.
In the event the operations of a property secured by such mortgage indebtedness
are insufficient to make debt payments on the debt secured by such property or
Parkway is unable to meet the required payments of principal and interest under
the Acquisition Facility, the lender may foreclose upon the mortgage which
secures its loan to Parkway and Parkway may lose title to such property.
 
REAL ESTATE INVESTMENT RISKS
 
     General Risks.  Parkway's assets consist primarily of equity investments in
office buildings and other types of real property. As a result, stockholders of
Parkway are subject to the risks inherent in the ownership and management of
real property owned by Parkway. These risks include, among others: adverse
changes in general or local economic conditions; adverse changes in interest
rates and in the availability of permanent mortgage financing which may render
the acquisition, sale or refinancing of properties difficult or unattractive;
existing laws, rules and regulations and judicial decisions regarding liability
for a variety of potential problems related to real estate generally; adverse
changes in real estate, zoning, environmental or land-use laws; increases in
real property taxes and federal or local economic or rent controls; other
governmental rules; increases in operating costs and the need for additional
capital and tenant improvements; the cash demands of tenant improvements and
leasing commission obligations; the supply of and demand for properties;
possible insolvencies and other material defaults by tenants; overbuilding in
certain markets; ability to obtain or maintain full occupancy of properties or
to provide for adequate maintenance or insurance; the presence of hazardous
waste materials; mechanics liens resulting from construction; property related
claims and litigation; fiscal policies; and acts of God. Certain significant
expenditures associated with investments in real estate (such as mortgage
payments, real estate taxes, insurance and maintenance costs and the cash
demands of tenant improvements and leasing commission obligations) are generally
not reduced when circumstances cause a reduction in rental revenues from the
property. In addition, real estate values and yields from investments in
properties may also be affected by such factors as conditions in financial
markets, environmental conditions and compliance with laws. If large numbers of
vacancies occur in Parkway's office properties, Parkway may be required to make
significant expenditures for marketing, tenant improvements and leasing
 
                                       S-6
<PAGE>   7
 
commissions in connection with attracting new tenants for such vacant space. Any
of these factors may adversely affect Parkway's net income, FFO and ability to
make expected distributions to stockholders.
 
     Dependence on Primary Markets.  A substantial percentage (93% on a square
footage basis) of Parkway's properties are located in the Southeastern United
States (primarily the states of Georgia, Mississippi, North Carolina, Tennessee
and Virginia) and Texas and such properties consist predominantly of office
properties. As of January 15, 1997, Parkway's office portfolio breakdown on a
square footage basis was 28% in Houston, Texas, 27% in Jackson, Mississippi, 12%
in Atlanta, Georgia, 11% in Winston-Salem, North Carolina, 8% in Memphis,
Tennessee and 7% in Northern Virginia. Therefore, Parkway's performance 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 the financial performance of
Parkway and adversely affect Parkway's net income, FFO and ability to make
expected distributions to stockholders.
 
     Market Illiquidity.  Equity real estate investments are relatively
illiquid. Such illiquidity will tend to limit Parkway's ability to vary its
portfolio promptly in response to changes in economic or other conditions. In
addition, the Code limits a REIT's ability to sell properties held for fewer
than four years, which may affect Parkway's ability to sell properties without
adversely affecting Parkway's status as a REIT and its ability to make expected
distributions to stockholders.
 
     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. Furthermore, Parkway
has more than one office property in certain markets (e.g., Houston, Texas,
Atlanta, Georgia and Jackson, Mississippi) and these properties may compete
against one another for the same tenants.
 
     Uninsured Loss.  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 management believes are
customarily obtained for similar properties. There are, however, certain types
of losses (generally of a catastrophic nature, such as earthquakes, floods and
wars) that may be either uninsurable or not economically insurable. Should such
an uninsured loss occur, Parkway could lose both its invested capital and
anticipated profits relating to such property as well as its ability to make
expected distributions to stockholders.
 
     Tenant Defaults.  A substantial part of Parkway's revenues and income is
derived from rental income from real property. Consequently, Parkway's 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 net income, FFO and ability to make expected
distributions to stockholders. If a tenant rejects its lease pursuant to
applicable bankruptcy 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).
 
     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
 
                                       S-7
<PAGE>   8
 
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, such costs could be
substantial. Parkway has not undertaken ADA studies of all of its properties
and, with respect to those properties with respect to which Parkway has not
undertaken ADA studies, possible costs of compliance could arise.
 
POSSIBLE ENVIRONMENTAL LIABILITIES
 
     Under various federal, state and local laws, ordinances and regulations, an
owner or operator of real estate is liable for the costs of investigation and
removal or remediation of certain hazardous or toxic substances on or in such
property. Such laws often impose liability without regard to whether the owner
or operator knew of, or was responsible for, the presence of such hazardous or
toxic substances. The presence of such substances, or the failure to properly
remediate such substances, may adversely affect the owner's ability to sell or
rent such property or to use such property as collateral in its borrowings.
 
     Management of Parkway is not aware of any environmental liability with
respect to the properties that management believes would have a material adverse
effect on Parkway's business, assets or results of operations. Phase I
environmental audits have been conducted at all but two of Parkway's properties
and such audit reports have not revealed any potential significant environmental
liability. Parkway will perform such audits with respect to properties acquired
in the future. No assurance can be given that there are no existing
environmental liabilities with respect to any of Parkway's properties, that the
audit reports revealed all pre-existing conditions or that any prior owner of
any such property did not create any material environmental condition not known
to Parkway.
 
     Asbestos was formerly used in commercial construction as a fireproofing and
insulation material. Under certain circumstances, asbestos can become a hazard
to the health of the occupants of buildings and it must be regularly monitored
to ensure that it has not become a health hazard. Parkway is not aware of any
material asbestos problems at the properties owned by Parkway, but is aware of
the presence of asbestos at one of its non-core properties. The fact that
asbestos is present in such property could have an adverse effect on the value
of such property. Further, there can be no assurance that asbestos problems do
not exist at other properties owned by Parkway. If there is asbestos in
Parkway's properties that requires removal or other remediation, the costs
thereof could be substantial.
 
RISKS OF FEE MANAGEMENT BUSINESS
 
     Parkway manages properties owned by third parties. Risks associated with
the management of properties owned by third parties include the risk that
management contracts will be terminated and that rental revenues upon which
management fees are based will decline, resulting in decreased management fee
income to Parkway.
 
LIMITS ON CHANGES IN CONTROL
 
     Certain provisions contained in Parkway's Charter and Bylaws, certain
Parkway 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 Shares" in the
accompanying Prospectus), Parkway's proposed Change of Control Agreements (see
"The Company -- Management") and certain provisions of the Charter intended to
protect Parkway's status as a REIT described below under "-- Possible Adverse
Consequences of Limits on Ownership of Common Shares." Such provisions may (i)
deter tender offers for Common Shares, which offers may be attractive to the
stockholders; or (ii) deter purchases of large blocks of Common Shares, thereby
limiting the opportunity for stockholders to receive a premium for their Common
Shares over then-prevailing market prices.

POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF COMMON SHARES
 
     The 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 Shares
(as defined below); (ii) the outstanding shares of Parkway being constructively
or beneficially owned by fewer than 100 persons; or (iii) Parkway being "closely
held" within the meaning of Section 856 of 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 Shares"), having no dividend or
voting rights. Holders of Excess Shares 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 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 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.
 
POSSIBLE ADVERSE IMPACT OF MARKET CONDITIONS ON MARKET PRICE
 
     The market value of the Common Shares 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 Shares to demand a higher annual dividend
yield on the Common Shares, which could adversely affect the market price of the
Common Shares. 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 Shares or other securities.
 
CONFLICTS OF INTEREST
 
     Leland R. Speed serves as Chairman and Chief Executive Officer of both
Parkway and EastGroup Properties, 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 sell, transfer
or acquire 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.

                                  THE COMPANY
 
GENERAL
 
     Parkway is a self-administered REIT specializing in the acquisition,
ownership, management and leasing of office properties in the Southeastern
United States (primarily the states of Georgia, Mississippi, North Carolina,
Tennessee and Virginia) and Texas. At January 15, 1997, Parkway owned or had an
interest in 18 office properties located in nine states with an aggregate of
approximately 2.15 million square feet of leasable space.
 
     Parkway's management team of office property specialists has proven
capabilities in office property (i) acquisition, (ii) ownership, (iii)
management, (iv) leasing and (v) development. Management believes that these
capabilities should allow Parkway to continue to create office property value in
all phases of the real estate cycle. Furthermore, management also believes it
has a proven capability for acquiring other real estate companies at attractive
prices.
 
     Since July 1995, Parkway has pursued a strategy of aggressively acquiring
office properties. Parkway seeks to invest in markets characterized by positive
employment and population growth with attractive real estate market dynamics and
investment conditions. Parkway also seeks to invest in office properties where
management can add value through direct asset and property management, a
"hands-on" operating strategy and Parkway's financial flexibility. Concurrently
with its recent office property acquisitions, Parkway has strategically disposed
of selected non-core assets which no longer fit into its investment strategy and
has redeployed the proceeds from such dispositions into office property
investments.
 
     Parkway's business objective is to maximize total return to stockholders
over time through increases in dividend distributions and share price
appreciation. Parkway has paid 41 consecutive quarterly cash distributions to
its stockholders. On December 6, 1996, Parkway announced a 79% increase in its
quarterly dividend from $0.14 per Common Share to $0.25 per Common Share. With
this increase, Parkway anticipates that its dividend payout ratio will
approximate 50% of its FFO for 1997. See "Recent Developments -- Funds From
Operations." This conservative dividend payout ratio should allow Parkway to
generate a significant amount of retained cash for use in the acquisition of
office properties.
 
ACQUISITION STRATEGY
 
     Parkway generally seeks to acquire well-located Class A, A- or B+
multi-story office buildings in primary or secondary markets in the Southeastern
region of the United States and Texas. Parkway generally targets for acquisition
office buildings ranging in size from 50,000 to 300,000 square feet with current
and projected occupancy levels in excess of 70% and with adequate parking to
accommodate full occupancy. Parkway targets buildings which are occupied by a
major tenant (or tenants) (e.g., a tenant that accounts for at least 30% of the
building's total rental revenue and has at least five years remaining on its
lease). Parkway attempts to purchase office buildings such that the initial
yield on its total investment (including purchase price, related acquisition
costs and capital expenditures generally anticipated for the 12 to 24 months
following purchase) will be in the range of 9% to 12% per annum. Parkway defines
initial yield as net operating income (revenues less property operating
expenses, before interest expenses and depreciation) for the calendar year of or
following acquisition divided by total investment. Parkway also generally seeks
to acquire properties whose total cost per square foot is at least 25% below
estimated replacement cost and whose current rental rates are at or below market
rental rates.
 
     Parkway believes that its focus on its existing and targeted high growth
markets in the Southeastern United States and Texas should provide further
opportunities to enhance stockholder value. Parkway is presently focusing its
resources on acquisitions in both its existing markets and targeted markets,
including, but not limited to, Charlotte, Dallas, Nashville, Tampa and Orlando.
Parkway has targeted these expansion markets based on positive economic
indicators such as higher than average job growth and household formation and
strong real estate market conditions.

ORGANIZATION
 
     Parkway and its predecessors have been public companies engaged in the real
estate business since 1971. Parkway was incorporated under the laws of the State
of Maryland on May 17, 1996 as a wholly-owned subsidiary of The Parkway Company,
a Texas corporation. Parkway merged with The Parkway Company on August 2, 1996
pursuant to the Agreement and Plan of Merger dated July 17, 1996 by and between
Parkway and The Parkway Company. As a result of the Merger, Parkway succeeded to
the business and operations of The Parkway Company. Additionally, on August 22,
1996 the Common Shares became listed on the NYSE under the symbol "PKY." Prior
to this date, the Common Shares had been quoted on the NASDAQ National Market
under the symbol "PKWY." Further, for the taxable year beginning January 1,
1997, Parkway intends to elect to qualify as a REIT under the Code.
 
     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
performs brokerage services to third parties on a commission basis and manages
and leases a portfolio of approximately 1.4 million square feet of office space
including Parkway's office buildings in Jackson, Mississippi. With respect to
Parkway's office buildings outside of Jackson, Mississippi, Parkway has retained
property managers on a fee-for-service basis or has formed strategic alliances
with property management firms in certain markets (i.e. Houston and Atlanta).
Parkway is currently evaluating its property management relationships to
determine whether self-management or additional strategic alliances would
provide more cost effective property management.
 
     Parkway's principal office is located at 300 One Jackson Place, 188 East
Capitol Street, Jackson, Mississippi 39201-2195. Its telephone number is (601)
948-4091.
 
MANAGEMENT
 
     Parkway's senior management team has worked together for the past ten
years. Leland R. Speed, Chairman and Chief Executive Officer, and Steven G.
Rogers, President, have an average of over 25 years of experience in the real
estate industry. Senior management also has experience in operating public
companies and management believes that it has a reputation within the real
estate community for creating value in the office property sector. Parkway's
senior officers and directors own approximately 12.6% of the issued and
outstanding Common Shares (9.7% after giving effect to the Offering). Officers
and directors acquired approximately 31,500 Common Shares in December 1996 and a
total of approximately 54,000 Common Shares since June 1996. Parkway believes
that this ownership level helps to ensure an alignment of management and
stockholder interests.
 
     The Compensation Committee of Parkway's Board of Directors has approved
Parkway's entering into a Change in Control Agreement (the "Change in Control
Agreement") with each of Parkway's executive officers (the "Executives"). The
Change in Control Agreement will provide that if an Executive's employment is
terminated or the Executive leaves Parkway's employment for certain reasons
during a defined period (30 months in the case of Leland R. Speed, Steven G.
Rogers and Sarah P. Clark and 20 months in the case of James Ingram, David
Fowler and G. Mitchell Mattingly after a Change in Control (as hereinafter
defined), Parkway will pay a lump sum benefit to the Executive equal to a
multiple of (2.5 times in the case of Messrs. Speed and Rogers and Ms. Clark and
1.667 times in the case of Messrs. Fowler, Ingram and Mattingly) the average of
the Executive's salary and accrued bonus for the three calendar year period
ending on the December 31 prior to the Change in Control. The Change in Control
Agreement also gives the Executive the ability to leave the employment of
Parkway at any time during the six month period after the Change in Control in
which case the Executive will receive the lump-sum payment of one-half of the
amount set forth above. Change in Control is defined in such agreement as (i)
any change in control of a nature that would be required to be represented under
the Exchange Act proxy rules; (ii) any person acquiring beneficial ownership of
securities representing 30 percent or more of the combined voting power of
Parkway's outstanding securities; (iii) certain changes in Parkway's Board of
Directors; (iv) certain mergers; or (v) the approval of a plan of liquidation by
Parkway.

space under a lease that expires March 31, 2003.
 
     Tensor Building, Houston, Texas.  In October 1996, Parkway acquired this
three-story office building for a purchase price of $2,820,000. This building
contains an aggregate of approximately 92,017 square feet of leasable space and
has a 332 space parking area of which 77 spaces are covered. At December 31,

primarily occupied by Tensor Geophysical, a tenant currently occupying
approximately 89,009 square feet of leasable space and whose lease expires
December 31, 2001.
 
     Proposed Acquisitions.  Parkway intends to acquire the following
properties:
 
     Charlotte Park Executive Center, Charlotte, North Carolina.  The Charlotte
Park Executive Center is a three-building office park located in Charlotte,
North Carolina containing an aggregate of 187,207 square feet of leasable space.
The Charlotte Park Executive Center was 90% leased at December 31, 1996. Premier
Health Systems occupies an aggregate of 92,523 square feet of leasable space
under leases that expire November 30, 1999. Bell South Business Systems occupies
43,540 square feet of leasable space under a lease that expires January 30,
1999. Parkway has a contract to purchase the Charlotte Park Executive Center for
$14,800,000, plus approximately $535,000 in related acquisition costs and
anticipated capital expenditures. This acquisition is still subject to Parkway's
due diligence review. Therefore, there can be no assurance that the purchase of
this office property will be completed.
 
     Ashford II and Ashford IV Office Buildings, Houston, Texas.  The Ashford II
Office Building is a two-story office building located in west Houston. The
building contains approximately 58,511 square feet of leasable space and has a
170 space parking area. The Ashford IV Office Building is also a two-story
office building located in west Houston. The Ashford IV Office Building contains
approximately 57,311 square feet of leasable space, has a 121 space parking area
and a 69 space underground parking area. The Ashford IV Office Building also
contains 17 storage rooms in the underground parking area which contain
approximately 3,900 square feet. As of December 31, 1996, the Ashford II and
Ashford IV Office Buildings were 91% leased. Consumer Credit Associates occupies
19,408 square feet of leasable space under a lease that expires December 31,
2001 and Operational Services, Inc. occupies 18,210 square feet of leasable
space under a lease that expires April 30, 1997. Parkway has a contract to
purchase this two-building portfolio for $4,303,000, plus $290,000 in related
acquisition costs and anticipated capital expenditures. The Phase I
environmental audit prepared for Parkway in connection with the acquisition of
this property indicated a small leak of hydraulic fluid in the shaft of a
hydraulic elevator in one of these buildings. Parkway's environmental consultant
is
 
                                      S-14
<PAGE>   15
 
performing additional investigation and testing to determine the extent of any
environmental conditions possibly resulting from this leak. The acquisition is
subject to Parkway's satisfaction with the results of the additional
environmental investigation and testing, further due diligence review and the
negotiation of definitive documentation. Therefore, there can be no assurance
that the purchase of these buildings will be completed.
 
     Other Office Acquisitions.  Parkway currently has more than $300 million of
office property acquisitions under consideration. It has non-binding letters of
intent with respect to two properties whose aggregate proposed purchase price
would be approximately $15,150,000. While there can be no assurance that Parkway
will acquire any of such properties and while it is unlikely that a large
percentage of these properties will ultimately be acquired by Parkway,
management expects to continue its aggressive acquisition pace while maintaining
Parkway's strict acquisition criteria.
 
     Other Business Transactions.  In addition to direct real estate
acquisitions, Parkway's investment strategy has also historically included the
consummation of business combination transactions with other public real estate
and financial companies which Parkway deemed to be undervalued. Since 1979,
Parkway has completed eight such business combinations. As a result of these
various business combinations, Parkway has acquired a portfolio of non-core real
estate assets, securities and mortgage loans, which it is proceeding to
liquidate. See "-- Dispositions."
 
RECENT FINANCINGS
 
     The Recent Acquisitions have been purchased with existing cash reserves,
bank borrowings and funds made available by the sale of non-core real estate
assets and securities and the collection of mortgage notes receivable. Following
the acquisition of office building investments, Parkway has obtained, and
intends to continue to seek to obtain, fixed rate, non-recourse mortgage
financing at fully-amortizing terms ranging from 12 to 15 years. Since December
1, 1995, Parkway has obtained $45,970,000 in such financing secured by eight of
the Recent Acquisitions, and has refinanced the mortgage on its One Jackson
Place office building for $18,400,000. These loans, which have a current
principal balance of approximately $62.8 million and comprise all of Parkway's
permanent indebtedness, have a weighted average remaining term of approximately
14 years and have a weighted average interest rate of 8.01% per annum.
 
     On April 2, 1996, the Board of Directors of Parkway approved a
three-for-two stock split effected as a dividend of one share for every two
shares outstanding, which dividend was payable on April 30, 1996 to stockholders
of record on April 15, 1996. In June 1996 Parkway completed a private placement
of 1,140,000 Common Shares to seven unaffiliated institutional investors for
$15.25 per share generating net proceeds of $16,612,000. Such proceeds were
utilized in the acquisition of additional office properties.
 
FUNDS FROM OPERATIONS
 
     Parkway generally considers FFO to be an appropriate supplemental measure
of the performance of Parkway because it is predicated on a cash flow analysis,
as opposed to other measures predicated on generally accepted accounting
principles which give effect to non-cash items such as depreciation. FFO, as
defined by the National Association of Real Estate Investment Trusts ("NAREIT")
and as followed by Parkway, represents net income (computed in accordance with
generally accepted accounting principles), excluding gains (or losses) from debt
restructuring and sales of property, plus depreciation and amortization, and
after adjustments for unconsolidated partnerships and joint ventures.
Adjustments for unconsolidated partnerships and joint ventures are calculated to
reflect FFO on the same basis. Since the definition of FFO is a guideline, the
computation of FFO may vary from one REIT to another. FFO does not represent
cash generated from operating activities in accordance with generally accepted
accounting principles and should not be considered as an alternative to net
income as an indicator of Parkway's operating performance or as an alternative
to cash flow as a measure of liquidity. In addition, FFO is not necessarily
indicative of cash available to fund cash needs. As a result of certain
interpretive guidance provided by NAREIT with respect to the calculation of FFO
(effective January 1996), all FFO amounts (including historical amounts) have
been restated in accordance with this interpretive guidance.

ELECTION OF REIT STATUS
 
     Until December 31, 1996 Parkway operated as a real estate operating
company. For the taxable years 1995 and 1996 Parkway paid and expects to pay
virtually no federal income taxes ($64,000 in 1995 and none projected for 1996)
primarily because Parkway has or will utilize certain net operating losses
("NOLs") to shelter most of Parkway's income from such taxes. However, the
increase in the number of outstanding Common Shares which resulted from the
completion of the private placement of Common Shares in June 1996 and Parkway's
recent mergers have caused the use of Parkway's NOLs to be significantly limited
in any one year. Accordingly, Parkway's Board of Directors has determined that
it is in the best interests of Parkway and its stockholders to elect to qualify
Parkway as a REIT under the Code for the taxable year beginning January 1, 1997,
which will allow Parkway to be generally exempt from federal income taxes even
if its NOLs are limited or exhausted, provided it meets various REIT
requirements. See "Federal Income Tax Considerations" in the accompanying
Prospectus.
 
DISPOSITIONS
 
     Since January 1, 1995, Parkway has pursued a strategy of liquidating its
non-core assets and using the proceeds from such sales to acquire office
properties. In accordance with this strategy, since January 1, 1995, Parkway has
sold non-core assets with a book value of approximately $36.9 million for
approximately $56.6 million, resulting in an aggregate gain for financial
reporting purposes of approximately $19.8 million. The book value of all
remaining non-office building real estate assets and mortgage loans, all of
which are for sale, was approximately $9.8 million as of December 31, 1996.
 
     Two of Parkway's major dispositions of non-core assets during 1996 involved
the sale of mortgage loans. On May 31, 1996, Parkway sold 157 of the loans in
its mortgage loan portfolio for approximately $9,888,000 in cash, net of
estimated expenses. These loans had a book value of $5,128,000, and the sale
resulted in a book gain of approximately $4,760,000. On December 24, 1996,
Parkway sold its interest in the second mortgage secured by the Pembroke Office
Park in Virginia Beach, Virginia (the "Virginia Beach Mortgage") for $9,700,000
in cash. A portion of the proceeds of the sale were used to repay seven
underlying first mortgages with an aggregate principal amount of $4,415,000,
with the remaining proceeds of $5,285,000 being retained by Parkway. The sale of
the Virginia Beach Mortgage resulted in a book gain of approximately $3,560,000.
 
DISTRIBUTIONS
 
     Parkway has paid 41 consecutive quarterly cash distributions to its
stockholders. On December 6, 1996, Parkway's Board of Directors declared an
increase in the quarterly distribution to $0.25 per Common Share ($1.00 per
share on an annualized basis). This represents a 79% increase from the 1996
third quarter dividend of $0.14 per Common Share and the second dividend
increase in 1996. With this increase, Parkway anticipates that its dividend
payout ratio will approximate 50% of its FFO for 1997. This conservative
dividend payout ratio should allow Parkway to generate a significant amount of
retained cash for use in the acquisition of office properties.

                                USE OF PROCEEDS
 
     The net proceeds to Parkway from the Offering are estimated to be
approximately $44.7 million after deducting fees and expenses of the Offering
payable by Parkway estimated to be approximately $2.5 million. Parkway intends
to use the net proceeds from the Offering for general corporate purposes,
including approximately $7.4 million to repay outstanding indebtedness under its
Working Capital Facility, approximately $19.9 million to fund the purchase of
the Proposed Acquisitions, and the remainder to fund working capital
requirements, including future acquisitions. The indebtedness being repaid with
the proceeds of the offering has an interest rate of LIBOR plus 2.35% (which is
7.91% as of January 15, 1997 and matures on June 30, 1997. 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, for example, certificates of deposit, interest-bearing bank deposits
and money market investments.

     Subject to the terms and conditions of the Underwriting Agreement (the
"Underwriting Agreement") between Parkway and PaineWebber, PaineWebber has
agreed to purchase from Parkway, and Parkway has agreed to sell to PaineWebber,
1,750,000 Common Shares.
 
     Parkway has been advised by PaineWebber that PaineWebber proposes to offer
the 1,750,000 Common Shares in part to the public at the price to the public set
forth on the cover page of this Prospectus Supplement, and in part to certain
securities dealers (who may include PaineWebber) at such price less a concession
not in excess of $0.80 per share; and that PaineWebber and such dealers may
reallow a discount not in excess of $0.10 per share to other dealers, including
PaineWebber.
 
     Parkway has granted to PaineWebber an option, exercisable during the 30-day
period after the date of this Prospectus Supplement, under which PaineWebber may
purchase up to 262,500 additional Common Shares from Parkway at the price to the
public set forth on the cover page of this Prospectus Supplement, less the
underwriting discounts and commissions. PaineWebber may exercise the option only
to cover overallotments, if any, made in connection with the offering of the
Common Shares offered hereby.
 
     Parkway and Parkway's executive officers and directors have agreed, with
limited exceptions, including the issuance of Common Shares pursuant to
Parkway's stock option plans, not to directly or indirectly, offer, sell,
contract to sell, grant any option to sell, or otherwise dispose of any Common
Shares, or securities exercisable or exchangeable for Common Shares or rights to
purchase or acquire Common Shares, for a period of 90 days after the date of
this Prospectus Supplement without the prior written consent of PaineWebber.
 
     Parkway 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.
 
     In the ordinary course of its business, PaineWebber and its affiliates have
engaged and may in the future engage in investment banking, financial advisory
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 Shares, will be
passed upon for Parkway by Jaeckle Fleischmann & Mugel, LLP, Buffalo, New York
and for PaineWebber by Rogers & Wells, New York, New York. As to matters of
Maryland law contained in these opinions, Jaeckle Fleischmann & Mugel, LLP and

                                  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>   23
 
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>   24
 
          (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>   25
 
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>   26
 
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>   27
 
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>   28
 
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.
 
                                       10
<PAGE>   29
 
     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>   30
 
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>   31
 
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>   32
 
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.

<PAGE>   34
 
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

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
 
                                       17
<PAGE>   36
 
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>   37
 
     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>   38
 
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>   39
 
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>   40
 
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>   41
 
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.

     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>   43
 
     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
 
                                       25
<PAGE>   44
 
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>   45
 
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>   46
 
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
<PAGE>   47
 
     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>   48
 
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.

     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.

     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
<PAGE>   51
 
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.
