                               WEEKS REALTY, L.P.
              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

1.  THE COMPANY

Weeks Realty, L.P., a Georgia limited partnership, (the "Operating
Partnership"), and its subsidiaries own, operate, develop, construct, acquire
and manage industrial and suburban office buildings in the southeast United
States and Texas.  Weeks Corporation, a Georgia corporation, through its wholly
owned subsidiaries, Weeks GP Holdings, Inc. and Weeks LP Holdings, Inc.,
referred to herein as the "Company," is the sole general partner and a limited
partner and owns a majority interest in the Operating Partnership.  The
Operating Partnership, including the operations of its subsidiaries, conducts
substantially all of the on-going operations of Weeks Corporation, a publicly
traded company which operates as a self-administered and self-managed real
estate investment trust ("REIT") under the Internal Revenue Code of 1986 (the
"Code").

As of June 30, 1998, the Company owned 74.1% of the common units of limited
partnership interest ("Common Units") in the Operating Partnership.  Common
Units held by persons other than the Company (the "Other Limited Partnership
Interests") represented a 25.9% partnership interest in the Operating
Partnership.  The Company's weighted average ownership interest in the Operating
Partnership was 74.3% and 75.9% for the three months ended and 73.9% and 75.8%
for the six months ended June 30, 1998 and 1997, respectively.

The Operating Partnership conducts its third-party service businesses through
two subsidiary companies (the "Service Companies"):  Weeks Realty Services, Inc.
and Weeks Construction Services, Inc.  Together the Service Companies and their
subsidiaries conduct third-party development, construction, landscape, property
management and commercial brokerage services.  The Operating Partnership holds
100% of the nonvoting and 1% of the voting common stock of the Service
Companies.  The remaining voting common stock is held by three executive
officers of the Company.  The ownership of the common stock of the Service
Companies entitles the Operating Partnership to substantially all (99%) of the
economic benefits from the results of the Service Companies' operations.

Under the provisions of the Operating Partnership's limited partnership
agreement, as amended, the Company is obligated, upon request to redeem each
Common Unit held by the Other Limited Partnership Interests for shares of Weeks
Corporation common stock on a one-for-one basis, or cash, at the Company's
option.  The Company currently anticipates that it will elect to issue common
stock for Common Units presented for redemption by the Other Limited Partnership
Interests in the Operating Partnership.  The Other Limited Partnership Interests
redemption rights are reflected in the caption "other limited partners' capital
interests" in the accompanying consolidated balance sheets at the cash
redemption price (computed using the Company's closing stock price as quoted on
the New York Stock Exchange) at the balance sheet dates.

Additionally, the terms of the limited partnership agreement obligate the
Company to contribute the net proceeds from the issuance of additional equity
securities, including issuances under the Company's incentive stock plan and
stock warrant agreements (see Note 5), to the Operating Partnership in exchange
for Units having substantially the same economic characteristics as the equity
securities issued by the Company.

Operating Partnership net profits, net losses and cash flow (after allocations
to preferred ownership interests) are allocated to the partners in proportion to
their common ownership interests.  Cash distributions from the Operating
Partnership shall be, at a minimum, sufficient to enable the Company to satisfy
its annual dividend requirements to maintain its REIT status under the Code.

As of June 30, 1998, the Operating Partnership's in-service property portfolio,
including one property totaling 86,000 square feet held in a 50% owned entity,
consisted of 259 industrial properties, 29 suburban office properties and 5
retail properties comprising 22,343,000 square feet.  The Operating
Partnership's primary markets and the concentration of the Operating
Partnership's in-service portfolio (based on square footage) are Atlanta,
Georgia (57.9%), Miami, Florida (11.1%), Raleigh-Durham-Chapel Hill, North
Carolina (10.3%), Nashville, Tennessee (9.8%), Dallas/Ft. Worth, Texas (4.8%),
Orlando, Florida (3.3%), Spartanburg, South Carolina (1.7%) and Jacksonville,
Florida (1.1%).  In addition, 44 industrial and suburban office properties and
one property expansion were under development or in lease-up and ten industrial
properties were under agreement to acquire as of June 30, 1998, comprising an
additional 6,966,000 square feet.

2.  BASIS OF PRESENTATION

The accompanying consolidated condensed financial statements include the
consolidated condensed financial position of the Operating Partnership and its
subsidiaries at June 30, 1998, and December 31, 1997, and their results of
operations and cash flows for the three and six months ended June 30 , 1998 and
1997. The Service Companies and their subsidiaries are reflected in the
accompanying consolidated condensed financial statements on the equity method of
accounting.  All significant intercompany balances and transactions have been
eliminated in the consolidated condensed financial statements.  Certain prior
year amounts have been reclassified to conform to the 1998 presentation.

The accompanying interim unaudited financial statements have been prepared by
the Operating Partnership's management in accordance with generally accepted
accounting principles for interim financial information and in conformity with
the rules and regulations of the Securities and Exchange Commission.  In the
opinion of management, the interim financial statements presented herein reflect
all adjustments of a normal and recurring nature which are necessary to fairly
state the interim financial statements.  The results of operations for the
interim periods are not necessarily indicative of the results that may be
expected for the year ending December 31, 1998.  These financial statements
should be read in conjunction with the Operating Partnership's audited financial
statements and the notes thereto included in the Operating Partnership's Annual
Report on Form 10-K for the year ended December 31, 1997.

RECENT ACCOUNTING PRONOUNCEMENTS
In June 1997, SFAS 131, "Disclosures About Segments of an Enterprise and Related
Information" was issued prescribing new guidelines for the reporting of segment
data.  SFAS 131 will apply to all public, for-profit companies and will be
effective for the Operating Partnership beginning with the fourth quarter and
year ending December 31, 1998.  The Operating Partnership was not subject to
segment reporting under prior accounting standards, but may be required to
provide certain segment disclosures under SFAS 131.  The Operating Partnership
continues to evaluate the disclosure provisions of SFAS 131 and plans to adopt
SFAS 131 in it financial statements for the year ending December 31, 1998.

In March 1998, Emerging Issues Task Force Issue No. 97-11, "Accounting for
Internal Costs Relating to Real Estate Property Acquisitions," was issued
prescribing that internal acquisition costs relating to the acquisition of
operating real estate properties should be expensed as incurred.  Effective with
the first quarter of 1998, the Operating Partnership implemented this new
guideline, which did not have a material impact on the Operating Partnership's
financial position or results of operations.

In June 1998, SFAS 133, "Accounting for Derivative Instruments and for Hedging
Activities," was issued prescribing new accounting standards for the accounting
and disclosures of derivative instruments and hedging transactions.  SFAS 133
will be effective for the Operating Partnership beginning January 1, 2000.  The
Operating Partnership is evaluating the provisions of SFAS 133 and plans to
adopt SFAS 133 in its financial statements beginning in 2000.

3.  BORROWINGS

UNSECURED NOTES
On March 20, 1998, the Operating Partnership issued $100,000,000 of 6.875%
unsecured notes due March 15, 2005.  A portion of the proceeds from the
unsecured notes totaling $4,566,000 was used to settle a treasury rate guarantee
hedge arrangement which was entered into in September 1997 to effectively fix
the interest rate on the unsecured note borrowing.  The costs to settle the
hedge were included in deferred financing costs and will be amortized over the
life of the unsecured notes as interest expense, resulting in an effective
interest rate of approximately 7.6%.  The unsecured notes are subject to certain
covenants, including those governing interest coverage and total leverage.

On August 4, 1998, the Operating Partnership issued $100,000,000 of 7.375%
unsecured notes due August 1, 2007.  The proceeds from these unsecured notes
were used to reduce borrowings under the Operating Partnership's revolving
credit facility.  These unsecured notes are subject to certain covenants,
including those governing interest coverage and total leverage.

CREDIT FACILITY
Effective July 1, 1998, the Company refinanced its existing $225,000,000
syndicated revolving line of credit (the "Line of Credit") and expanded its bank
lending group to five banks.  Additionally, effective July 1, 1998, the
Operating Partnership entered into a $20,000,000 swing revolving credit facility
(the "Swing Facility") with one bank.  The combined Line of Credit and the Swing
Facility are referred to herein as the "Credit Facility."  The new Credit
Facility remains unsecured and can be used for development and construction,
acquisitions and general corporate purposes.  The entire Credit Facility is
guaranteed by the Company.  The Operating Partnership are required to meet
certain financial and non-financial covenants including those governing the
Operating Partnership's maximum unsecured borrowings, total leverage,
limitations on secured borrowings and a restriction on the amount of dividends
and distributions to not more than 95% of "funds from operations," a REIT
industry measure of operating performance, unless the additional amounts are
necessary to maintain the Company's REIT status under the Code.  The Line of
Credit matures on December 31, 2000, and may be extended annually through
December 31, 2002, subject to annual extension fees of 0.10%.  The Swing
Facility matures on June 30, 1999, and may be extended annually.

In prior periods, the Service Companies and Weeks Development were direct
borrowers under the Credit Facility.  In connection with the issuance of the
unsecured notes in March 1998 and the refinancing of the Credit Facility
discussed above, the Service Companies and Weeks Development refinanced their
Credit Facility borrowings with intercompany loans from the Operating
Partnership (see Note 4).

Through June 30, 1998, interest under the Credit Facility accrued at bank prime
minus 0.25% or at LIBOR plus 1.05% at the election of the Operating Partnership.
The weighted average interest rate on Credit Facility borrowings, excluding the
effect of the interest rate swap agreements described below, was 6.7% at June
30, 1998.  Fees on the unused portion of the Credit Facility were 0.15%.
Effective July 1, 1998, interest accrues at bank prime minus 0.25% or at LIBOR
plus 0.80% at the election of the Operating Partnership.  In addition, the
Operating Partnership pays annual facility fees equal to 0.15% of the total Line
of Credit.

Interest paid, net of amounts capitalized, totaled $9,710,000 and $9,250,000 for
the six months ended June 30, 1998 and 1997, respectively.  Interest costs
capitalized totaled $2,697,000 and $1,283,000 for the

                                       9
<PAGE>
 
three months and $4,859,000 and $2,222,000 for the six months ended June 30,
1998 and 1997, respectively.

At June 30, 1998, the Operating Partnership had in place three interest rate
swap agreements with a commercial bank to effectively change the interest costs
on $50,000,000 of Credit Facility borrowings from the variable rates discussed
above to fixed rates.  The agreements, with notional principal amounts of
$10,000,000, $10,000,000 and $30,000,000, mature in July 1998, July 1999 and
July 2001 with effective fixed interest rates of 7.4%, 7.6% and 7.8%,
respectively.

As discussed in Note 3 and effective March 17, 1998, the operations of the
Service Companies and their subsidiaries are financed through line of credit
borrowings from the Operating Partnership.  These line of credit borrowings
accrue interest at bank prime plus 1%, payable monthly, and are due on demand.
Previously, these entities were financed through direct borrowings under the
Credit Facility.  As part of these financing arrangements, the Service Companies
and their subsidiaries have agreed not to incur any additional unsecured
borrowings other than through borrowings from the Operating Partnership.
Borrowings from the Operating Partnership also include $10,900,000 of 12% notes
due in 2004.

In connection with the Operating Partnership's January 1998 acquisition of a
real estate portfolio in Miami, Florida (see Note 7), the Service Companies
acquired a one-third interest in Codina Group, Inc. ("Codina"), a Miami-based
real estate services company, for aggregate consideration of approximately
$9,600,000.

5.  PARTNERS' CAPITAL

In April 1998, the Operating Partnership paid distributions to Common
Unitholders of $12,075,000 or $0.465 per Common Unit and to Preferred
Unitholders of $3,000,000 of $0.50 per unit relating to first quarter 1998
operating results.  In July 1998, the Operating Partnership paid distributions
to Common Unitholders of $12,222,000 or $0.465 per Common Unit and to Preferred
Unitholders $3,000,000 or $0.50 per unit relating to second quarter 1998
operating results.

In the first quarter of 1998, the Operating Partnership issued Common Units to
the Company totaling 1,072,797 and 468,750 and received net proceeds of
$33,100,000 and $14,100,000, respectively.  The cash contributions discussed
above result from the contribution by the Company of the net proceeds from the
sale of Company common stock in the public equity markets.  The proceeds were
used to reduce the Operating Partnership's outstanding Credit Facility
borrowings.

In February 1998, the Company contributed $1,400,000 to the Operating
Partnership resulting from the Company's sale of 350,000 common stock warrants.
In return, the Operating Partnership agreed to issue 350,000 Common Units to the
Company in exchange for an exercise price of $32.75 per Common Unit upon the
exercise of such warrants.  The terms of this agreement are structured to
parallel the terms of the Company's sale of 350,000 common stock warrants with
an exercise price of $32.75 per common share.  The Operating Partnership's
obligation to issue Common Units and the Company's common stock warrants expire
in February 2008.

6.  NET INCOME PER COMMON UNIT

The Operating Partnership adopted the provisions of SFAS 128 for the year ended
December 31, 1997.  For the three and six months ended June 30, 1998 and 1997,
reconciliations of income available to Common Unitholders and weighted average
Common Units used in the Operating Partnership's basic and diluted net income
per Common Unit computations are detailed below (in thousands, except per share
data):

</TABLE>

Basic net income per Common Unit for the periods presented was computed by
dividing income available to Common Unitholders by the weighted average number
of Common Units outstanding during the period.  Diluted net income per Common
Unit was computed based on the dilutive effect of the Company's stock options
outstanding.  Common Units issuable upon the exercise of outstanding Company
common stock warrants were not dilutive for the three months ended March 31,
1998.

Previously reported net income per Common Unit under prior accounting standards
was equal to basic net income per Common Unit under SFAS 128.

7.  ACQUISITIONS

In June 1998, the Operating Partnership acquired five industrial buildings
totaling approximately 1,074,000 square feet and 67.9 acres of undeveloped land
located in Dallas/Ft. Worth, Texas.  The aggregate acquisition consideration of
approximately $48,300,000 was paid in cash, funded through Credit Facility
borrowings.  The second phase of this acquisition consisting of four industrial
buildings and total anticipated aggregate acquisition consideration of
approximately $40,200,000 is expected to close in September 1998, and is subject
to customary closing conditions and the updating of due diligence procedures.
The actual acquisition consideration for these four buildings will be based on
actual occupancy levels achieved prior to the expected closing date, with a
minimum aggregate acquisition price of approximately $32,500,000.

Additionally, in the second quarter of 1998, the Operating Partnership acquired
ten industrial and suburban office buildings totaling approximately 467,000
square feet for approximately $29,550,000.  The aggregate acquisition
consideration was comprised of the issuance of $3,264,000 of Common Units, the
assumption of mortgage indebtedness of $2,949,000 and $23,337,000 of cash,
funded through Credit Facility borrowings.  The acquired properties are located
in Tennessee, Florida, North Carolina and Georgia.

On January 9, 1998, the Operating Partnership acquired a 2,477,000 square foot,
24-building portfolio and approximately five acres of land subject to ground
leases in Miami, Florida.  Aggregate acquisition consideration of approximately
$175,200,000, including closing costs and acquisition expenses, consisted of the
issuance of $28,310,000 of Common Units, the assumption of $78,033,000 of
mortgage indebtedness (see Note 3), the assumption of certain other liabilities
in excess of certain other assets of approximately $4,224,000, and cash of
approximately $64,633,000 funded through Credit Facility borrowings.  In
connection with the acquisition, the Operating Partnership has also agreed,
subject to customary closing conditions and the completion of due diligence
procedures, to acquire a 90,000 square foot building under development for
approximately $5,100,000 and approximately nine acres of adjacent, undeveloped
land for approximately $4,000,000.

Additionally, in the first quarter of 1998, the Operating Partnership acquired
two industrial buildings under development totaling approximately 102,800 square
feet for approximately $4,400,000.   The aggregate acquisition consideration was
comprised of the issuance of $1,514,000 of Common Units and $2,886,000 of cash,
used to fund the assumption and repayment of indebtedness, closing costs and
acquisition expenses, funded through Credit Facility borrowings.

Period to period comparisons of property operating revenues and expenses for
1998 and 1997 are discussed herein using the categories "core properties,"
"development properties" and "acquisition properties."  Core properties are
defined as properties which were stabilized and operating as of January 1, 1997.
The Operating Partnership defines a property as stabilized upon the earlier of
substantial lease-up or one year from building shell completion.  Development
properties reflect properties completed and stabilized, and acquisition
properties are properties acquired, subsequent to January 1, 1997.

For the comparable three and six months ended June 30, 1998 and 1997, operating
results of the core properties, representing 191 properties totaling
approximately 13,474,000 square feet, are summarized below (in thousands):

COMPARISON OF OPERATING RESULTS FOR THE THREE MONTHS ENDED JUNE 30, 1998, TO THE
THREE MONTHS ENDED JUNE 30, 1997
Property operating revenues (rental revenue plus tenant reimbursements)
increased $14,694,000 or 69.5% between periods.  Of this increase, $10,503,000,
$3,753,000 and $438,000 were attributable to acquisition, development and core
properties, respectively.  The increases relating to acquisition and development
properties were due to the acquisition of 76 properties (37 in 1997 and 39 in
1998) totaling approximately 6,152,000 square feet and the stabilization of 25
development properties (14 in 1997 and 11 in 1998) and two property expansions
(both in 1997) totaling approximately 2,630,000 square feet.  Property operating
expenses increased $7,279,000 or 71.1% between periods due primarily to the
growth in the property portfolio resulting from the acquisition and development
properties discussed above.

Property operating revenues from core properties increased 2.2% despite a
decrease in overall average occupancy of approximately 1.2%.  This increase was
due to both rental rate and reimbursement increases between periods.  Property
operating expenses increased 3.0% due primarily to increased maintenance
expenses in 1998.  Property operating revenues less property operating expenses
from core properties increased 1.6%, exclusive of depreciation and amortization
expense.

Interest expense increased by $2,561,000 or 54.3% from $4,714,000 for the three
months ended June 30, 1997, to $7,275,000 for the three months ended June 30,
1998, due to increased mortgage interest of $1,764,000 related to mortgage debt
assumed in connection with certain of the Operating Partnership's 1997 and 1998
property acquisitions and increased net interest expense on unsecured Credit
Facility and note borrowings due primarily to higher average borrowings in 1998
compared to 1997.

Operating Partnership general and administrative expenses increased by $459,000
or 52.5% from $875,000 for the three months ended June 30, 1997, to $1,334,000
for the three months ended June 30, 1998, due primarily to increased personnel
and related costs associated with the Operating Partnership's geographic
expansion.  As a percentage of total revenue, general and administrative
expenses decreased from 4.1% in the second quarter of 1997 to 3.7% in the second
quarter of 1998.

Interest income decreased $58,000 or 19.0% from $305,000 for the three months
ended June 30, 1997 to $247,000 for the three months ended June 30, 1998, due
primarily to the settlement of approximately $7,900,000 of real estate loans in
1998.

Equity in earnings of unconsolidated service companies represents the Operating
Partnership's 99% economic interest in the earnings of the Service Companies and
their subsidiaries after the elimination of interest expense and intercompany
profits to the Operating Partnership (see Note 4 to the consolidated condensed
financial statements).  Equity in earnings of the Service Companies and their
subsidiaries decreased by $175,000 or 30.4% from $576,000 for the three months
ended June 30, 1997, to $401,000 for the three months ended June 30, 1998, due
primarily to lower profits from land and property sales in 1998.  Equity in
earnings of unconsolidated real estate entities of $86,000 in 1998 represents
the Operating Partnership's 50% share of earnings from a single building equity
investment.

COMPARISON OF OPERATING RESULTS FOR THE SIX MONTHS ENDED JUNE 30, 1998, TO THE
SIX MONTHS ENDED JUNE 30, 1997
Property operating revenues (rental revenue plus tenant reimbursements)
increased $27,442,000 or 67.4% between periods.  Of this increase, $19,033,000,
$7,342,000 and $1,067,000 were attributable to acquisition, development and core
properties, respectively.  The increases relating to acquisition and development
properties were due to the acquisition of 76 properties (37 in 1997 and 39 in
1998) totaling approximately 6,152,000 square feet and the stabilization of 25
development properties (14 in 1997 and 11 in 1998) and two property expansions
(both in 1997) totaling approximately 2,630,000 square feet.  Property operating
expenses increased $13,549,000 or 68.4% between periods due primarily to the
growth in the property portfolio resulting from the acquisition and development
properties discussed above.

Property operating revenues from core properties increased 2.7% despite the
impact of lost property operating revenues of approximately $73,000 from the
sale of a 96,000 square foot building in April 1997 and a decrease in overall
average occupancy of approximately 1.0%.  Adjusted for the building sale
discussed above, property operating revenues from core properties increased
approximately 2.9%.  This increase was due to both rental rate and reimbursement
increases between periods.  Property operating expenses increased 3.5% due
primarily to increased utilities and maintenance expenses in 1998.  Property
operating revenues less property operating expenses from core properties
increased 2.5%, exclusive of depreciation and amortization expense and after
adjusting for the building sale discussed above.

Interest expense increased by $3,371,000 or 33.7% from $10,006,000 for the six
months ended June 30, 1997, to $13,377,000 for the six months ended June 30,
1998, due primarily to increased mortgage interest of $3,188,000 related to
mortgage debt assumed in connection with certain of the Operating Partnership's
1997 and 1998 property acquisitions.

Operating Partnership general and administrative expenses increased by $862,000
or 49.2% from $1,752,000 for the six months ended June 30, 1997, to $2,614,000
for the six months ended June 30, 1998, due primarily to increased personnel and
related costs associated with the Operating Partnership's geographic expansion.
As a percentage of total revenue, general and administrative expenses decreased
from 4.2% in the first half of 1997 to 3.8% in the first half of 1998.

Equity in earnings of unconsolidated service companies represents the Operating
Partnership's 99% economic interest in the earnings of the Service Companies and
their subsidiaries after the elimination of interest expense and intercompany
profits to the Operating Partnership (see Note 4 to the consolidated condensed
financial statements).  Equity in earnings of the Service Companies and their
subsidiaries decreased by $335,000 or 27.4% from $1,224,000 for the six months
ended June 30, 1997, to $889,000 for the six months ended June 30, 1998, due
primarily to lower net profits from the Operating Partnership's third-party
service businesses resulting from higher overhead expenses in 1998.  The Service
Companies incurred higher overhead as they expanded their businesses in the
Operating Partnership's markets outside Atlanta, Georgia.  Equity in earnings of
unconsolidated real estate entities of $154,000 in 1998 represents the Operating
Partnership's 50% share of earnings from a single building equity investment.

LIQUIDITY AND CAPITAL RESOURCES
The Operating Partnership continues to generate increasing cash flows from
operations.  Cash provided by operating activities increased from $23,416,000
for the six months ended June 30, 1997, to $40,094,000 for the six months ended
June 30, 1998, due primarily to the growth in the Operating Partnership's

                                       20
<PAGE>
 
operating income resulting from 25 development properties (14 in 1997 and 11 in
1998) and two property expansions (both in 1997) stabilized and from 76
buildings acquired (37 in 1997 and 39 in 1998).

The Operating Partnership's net cash flow from operations is currently
sufficient to meet the Operating Partnership's current operational needs and to
satisfy the Operating Partnership's current quarterly distributions on both its
common and preferred units, which are structured to ensure that the Company can
satisfy the dividend requirements necessary to maintain its status as a REIT.
Management believes that operating cash flows will continue to be adequate to
fund these requirements in 1998.

In the six months ended June 30, 1998, the Operating Partnership invested
$227,407,000 of cash in property acquisition, development and construction
activities.  This compares to $80,647,000 for the same six month period in 1997.
This increased cash investment activity primarily reflects the increased cash
component of the Operating Partnership's building acquisition activity in 1998
compared to 1997 of approximately $97,011,000 with the remaining increase due to
increased development and land acquisition activity.

Financing for the Operating Partnership's property investment activities
primarily consisted of $94,141,000 of net proceeds from unsecured note
borrowings, $47,200,000 from common equity offerings and $104,890,000 from
Credit Facility borrowings in the first half of 1998, compared primarily to
$106,568,000 from a common equity offering in the first half of 1997.  The debt
and equity components of the Operating Partnership's ongoing financing strategy
may differ from period-to-period based upon market conditions.

In addition to its operating cash flow, the Operating Partnership has aggregate
borrowing capacity of $245,000,000 under the Credit Facility (see Note 3 to the
consolidated condensed financial statements), which may be used, among other
things, to meet its operational obligations and to fund the distributions
necessary for the Company to meet its annual REIT dividend requirements.  The
Operating Partnership currently intends to finance its development, construction
and acquisition activities primarily through borrowings under the Credit
Facility, and to periodically refinance such borrowings with longer term debt or
equity.  On August 4, 1998, subsequent to the reduction of Credit Facility
borrowings from the net proceeds of approximately $98,300,000 from an unsecured
note issuance, the Company had available capacity under the Credit Facility of
approximately $108,400,000.

The Operating Partnership believes it has adequate liquidity, borrowing capacity
and sources of capital, including available capacity under its existing Credit
Facility and remaining capacity of approximately $650,000,000 under a universal
shelf registration statement, to meet its current operational requirements, to
fund annual principal repayments under existing mortgage notes payable, and to
fund its current development and acquisition activity.  It is management's
expectation that the Operating Partnership will continue to have access to the
additional capital resources necessary to further expand and develop its
business and to refinance mortgage notes payable as they mature.  These
resources include the expansion of the available borrowing capacity under the
Credit Facility and other forms of debt and equity financing, in both public and
private markets.  The Operating Partnership has unsecured investment grade
corporate debt ratings which may assist it in accessing the corporate debt
market in future periods.  Future development and acquisition activities will be
undertaken by the Operating Partnership only as suitable opportunities arise.
Such activities are not expected to be undertaken unless adequate sources of
financing are available and a satisfactory budget with an appropriate return on
investment has been internally approved.  The Operating Partnership maintains
staffing levels sufficient to meet its existing construction and leasing
activities and capitalizes a portion of the costs relating to

                                       21
<PAGE>
 
these activities to development projects and leasing transactions, respectively.
If market conditions warrant, the Operating Partnership may adjust staffing
levels to avoid a negative impact on the Operating Partnership's results of
operations.

Total consolidated debt amounted to $552,675,000 at June 30, 1998, including
borrowings under the Credit Facility of $187,810,000, mortgage notes payable of
$264,865,000 and unsecured notes of $100,000,000.  Of the $264,865,000 of
mortgage indebtedness, $259,091,000 is fixed rate and $5,774,000 is variable
rate.  The weighted average interest rate on the Operating Partnership's fixed
rate mortgage debt was 8.2% and on its variable rate mortgage debt was 3.9% at
June 30, 1998.  The weighted average interest rate under the Credit Facility at
June 30, 1998 (excluding the effect of the interest rate swap agreements
described below) was 6.7%.  The weighted average effective interest rate on the
Operating Partnership's fixed rate unsecured notes was 7.6% at June 30, 1998
(see Note 3).  At June 30, 1998, the Operating Partnership had in place interest
rate swap agreements to fix the Operating Partnership's interest costs on
$50,000,000 of the Operating Partnership's Credit Facility borrowings.   The
weighted average effective interest rate under the fixed swap arrangements was
approximately 7.7%.  If interest rates under the Credit Facility, in excess of
the $50,000,000 discussed herein, and under the Operating Partnership's variable
rate mortgage debt, fluctuated by 1%, interest costs to the Operating
Partnership, before capitalization of interest, if any, based on outstanding
borrowings at June 30, 1998, would increase or decrease by approximately
$1,400,000 on an annualized basis.  As discussed earlier, in August 1998, the
Operating Partnership reduced its Credit Facility borrowings by approximately
$98,300,000, thus reducing its exposure to interest rate changes.

Based on the outstanding balance of mortgage notes payable at June 30, 1998, the
weighted average interest rates on the mortgage notes with a final maturity in
each of the next five years were 7.4% in 1999, 8.7% in 2000, 7.4% in 2001, 8.2%
in 2002 and 8.3% in 2003.

At June 30, 1998, including total consolidated debt of $552,675,000 and
$2,000,000 of other notes payable of unconsolidated entities, the total debt
obligations of the Operating Partnership and its unconsolidated entities were
$554,675,000 or 36% of total market capitalization.  At June 30, 1998 (based on
the closing price of the common stock of the Company of $31.625 on June 30,
1998), the 26,350,034 Common Units outstanding would have a total market value
of $833,320,000, 6,000,000 preferred units outstanding would have a total
liquidation value of $150,000,000 and the 350,000 Common Units issuable upon the
exercise of the Company's common stock warrants outstanding would have an
estimated market value of $1,400,000, resulting in a total equity value of
$984,720,000.

CURRENT DEVELOPMENT AND ACQUISITION ACTIVITY
At June 30, 1998, the Operating Partnership had committed development and
acquisitions totaling approximately $362,306,000, representing 54 buildings and
one property expansion totaling 6,966,000 square feet.  Including new
acquisition and development activity, net of closed acquisitions and the
stabilization of development properties, between July 1, 1998 and August 11,
1998, the Operating Partnership had, at August 11, 1998, committed development
and acquisitions totaling approximately $368,390,000, representing 54 buildings
and one property expansion totaling 7,005,000 square feet.   Properties under
agreement to acquire  as of August 11, 1998, consisted of seven buildings,
totaling 1,206,000 square feet, with a total expected cost of approximately
$57,495,000.  Development properties as of August 11, 1998, consisted of 47
buildings and one property expansion, totaling 5,799,000 square feet, with a
total expected cost of approximately $310,895,000.

It is expected that such development and acquisition properties will stabilize
or be acquired as detailed below:

(a)  For development properties represents the entire estimated cost of the
     property at the estimated stabilization date.

In addition, the Operating Partnership has committed, subject to closing
conditions and the completion of due diligence procedures, to acquire
development land totaling $29,510,000 over various periods ranging up to five
years.

It is expected that future development and land acquisition expenditures will be
funded primarily through Credit Facility borrowings, refinanced as required
through new debt or equity offerings in both private and public markets, and
future acquisitions will be consummated primarily through a combination of cash
funded through borrowings under the Credit Facility, the issuance of Common
Units and the assumption of indebtedness, some of which will also be repaid
through borrowings under the Credit Facility.

The information provided above includes Forward-looking Statements about
expected property acquisitions or stabilizations that is based on current
construction schedules, the status of lease negotiations with potential tenants,
the successful completion of due diligence procedures and other relevant factors
currently available to the Operating Partnership.  There can be no assurance
that any of these factors will not change or that any change will not affect the
accuracy of such Forward-looking Statements.

SUPPLEMENTAL DISCLOSURE OF FUNDS FROM OPERATIONS
The Operating Partnership believes that funds from operations provides an
additional indicator of the financial performance of the Company.  Funds from
operations is defined by the National Association of Real Estate Investment
Trusts ("NAREIT") to mean net income (loss) determined in accordance with
generally accepted accounting principles ("GAAP") excluding gains (or losses)
from debt restructuring and sales of property, plus depreciation and
amortization of real property, and after adjustments for unconsolidated
partnerships and joint ventures.  Adjustments for unconsolidated partnerships
and joint

                                       23
<PAGE>
 
ventures will be calculated to reflect funds from operations on the same basis.
Funds from operations is influenced not only by the operations of the
properties, but also by the capital structure of the Operating Partnership.
Accordingly, the Company expects that funds from operations will be one of the
factors considered by its Board of Directors in determining the amount of cash
distributions the Operating Partnership will pay to its unitholders.  The
Operating Partnership computes funds from operations under the current NAREIT
definition by subtracting from net income the dividends to preferred unitholders
before making an adjustment for the non-cash items described above.  Funds from
operations does not represent cash flow from operating, investing and financing
activities as defined by GAAP, which are discussed under "Liquidity and Capital
Resources."  Additionally, funds from operations does not measure whether cash
flow is sufficient to fund all cash flow needs, including principal
amortization, capital expenditures and dividends to shareholders, and should not
be considered as an alternative to net income for purposes of evaluating the
Operating Partnership's operating performance or as an alternative to cash flow,
as defined by GAAP, as a measure of liquidity.  Funds from operations presented
herein is not necessarily comparable to funds from operations presented by other
real estate companies due to the fact that not all real estate companies
calculate funds from operations in the same manner.  However, the Operating
Partnership's funds from operations is comparable to the funds from operations
of real estate companies that use the current NAREIT definition.

The Operating Partnership's calculation of funds from operations follows the
guidelines issued by NAREIT, including the recognition of rental income on the
"straight-line" basis consistent with its treatment in the Operating
Partnership's statement of operations under GAAP.  The "straight-line" rental

RECENT ACCOUNTING PRONOUNCEMENTS
In June 1997, SFAS 131, "Disclosures About Segments of an Enterprise and Related
Information" was issued prescribing new guidelines for the reporting of segment
data.  SFAS 131 will apply to all public, for-profit companies and will be
effective for the Operating Partnership beginning with the fourth quarter and
year ending December 31, 1998.  The Operating Partnership is reporting under
prior accounting standards, but may be required to provide certain segment
disclosures under SFAS 131.  The Operating Partnership continues to evaluate the
disclosure provisions of SFAS 131 and plans to adopt SFAS 131 in it financial
statements for the year ending December 31, 1998.

In March 1998, Emerging Issues Task Force Issue No. 97-11, "Accounting for
Internal Costs Relating to Real Estate Property Acquisition," was issued
prescribing that internal acquisition costs relating to the acquisition of
operating real estate properties should be expensed as incurred.  Previously,
the Operating Partnership capitalized such costs to its acquisition properties.
The implementation of this new guidance will not have a material impact on the
Operating Partnership's financial statements.

In June 1998, SFAS 133, "Accounting for Derivative Instruments and for Hedging
Activities," was issued prescribing new accounting standards for the accounting
and disclosures of derivative instruments and hedging transactions.  SFAS 133
will be effective for the Operating Partnership beginning January 1, 2000.  The
Operating Partnership is evaluating the provisions of SFAS 133 and plans to
adopt SFAS 133 in its financial statements beginning in 2000.

IMPACT OF INFLATION
In the last three years, inflation has not had a significant impact on the
Operating Partnership because of the relatively low inflation rate.
Substantially all tenant leases do, however, contain provisions designed to
protect the Operating Partnership from the impact of inflation.  Most of the
leases require tenants to pay their share of operating expenses, including
common area maintenance, real estate taxes and insurance, thereby reducing the
Operating Partnership's exposure to increases in costs and operating expenses
resulting from inflation.  In addition, many of the leases are for terms of less
than seven years, which may enable the Operating Partnership to replace existing
leases with new leases at higher base rentals if rents under the existing leases
are below the then-existing market rate.  However, there can be no assurance
that the Operating Partnership would be able to replace existing leases with new
leases at higher base rentals.

OTHER MATTERS
The Operating Partnership continues to assess the potential impact of the year
2000 on the processing of date-sensitive information by the Operating
Partnership's hardware and software information systems.  The year 2000 issue is
the result of many computer programs recognizing a date ending with "00" as the
year 1900 rather than the year 2000, causing potential system failures or
miscalculations which could result in disruptions of normal business operations.
The Operating Partnership's primary financial and operating systems are supplied
by third-party suppliers.  Based on communications with these third-party
suppliers, evaluations of third-party systems and internal assessments of in-
house information systems, the costs of addressing potential year 2000 issues
are not expected to have a material adverse impact on the Operating
Partnership's financial position, results of operations or cash flows in future
periods.  In fact, most of the Operating Partnership's software systems are
either currently year 2000 compliant or will be compliant well in advance of
January 1, 2000.  However, such conclusions are based upon communications,
evaluations and assessments to date, and if future negative events occur which
can not be resolved in a timely manner, it could results in material financial
risk to the Operating Partnership.  To date, the Operating Partnership has not
incurred any material incremental costs relating to this matter.

Additionally, the Company is assessing the potential impact of the year 2000
issue resulting from the potential failure of its key building mechanical
systems and the failure of its major vendors, suppliers and tenants to be year
2000 compliant.  Any significant failures in these areas could result in a
material disruption of the Company's business.  The Company anticipates the
completion of its assessments and evaluations in these areas by early 1999.  The
Operating Partnership plans to allocate the time and resources necessary to
timely resolve any significant year 2000 issues.

PART II - OTHER INFORMATION
ITEM 2 - CHANGE IN SECURITIES

       During the three months ended June 30, 1998, the Operating Partnership
       issued a total of 171,142 Common Units, in full or partial consideration
       for the acquisition of real estate properties.  The aggregate value of
       the properties acquired by the Operating Partnership in exchange for such
       Common Units was approximately $5,455,000.  Common Units are convertible
       by their holders into shares of Company common stock on a one-for-one
       basis, or into cash, at the Company's option.  The Common Units were
       issued pursuant to an exemption from registration under Section 4(2) of
       the Securities Act in reliance, in part, upon the representations and
       warranties set forth in the acquisition agreements.  Certain of these
       Common Units are subject to registration rights and lock-up agreements
       which generally restrict the disposition of the Common Units until the
       designated lock-up periods expire.

Notwithstanding the foregoing, if the Expiration Date is not extended for an
additional one year period on each Extension Date, there shall be no further
Extension Dates or extensions of the Expiration Date.  Only one such request for
an extension may be made in any one calendar year, and IN NO EVENT SHALL THE
EXPIRATION DATE BE EXTENDED BEYOND DECEMBER 31, 2002.

     2.03  RATE OF INTEREST ON LOANS.  Interest shall accrue on the unpaid
           -------------------------                                        
principal amount of each Loan, at the election of Borrower as set forth in
notices given in accordance with Section 2.04, at the Floating Rate or the LIBOR
Rate, provided that no more than ten (10) LIBOR Rate Loans shall be outstanding
      --------                                                                 
at any one time.

     2.04  NOTICE AND MANNER OF BORROWING.
           ------------------------------   

          (a) Borrower shall give Agent an Advance Request prior to 10:00 a.m.
(Atlanta, Georgia time) on the same Domestic Business Day for each Base Rate
Loan and at least three (3) Euro-Dollar Business Days before each LIBOR Rate
Loan.

          (b) Upon receipt of an Advance Request, Agent shall promptly notify
each Bank of the contents thereof and of such Bank's ratable share of the Loan.
Such Advance Request, once received by Agent, shall not thereafter be revocable.

                                      -24-
<PAGE>
 
          (c) Not later than 2:00 p.m. (Atlanta, Georgia time) on the date of
each Loan (or, if the notice required to be given by Agent pursuant to paragraph
(b) of this Section 2.04 shall be given later than 12:00 noon (Atlanta, Georgia
time) on the date of any Loan, not later than two (2) hours following the time
such notice is given on the date of the Loan), each Bank shall (except as
provided in paragraph (d) of this Section 2.04) make available its ratable share
of such Loan, in federal or other funds immediately available in Atlanta,
Georgia, to Agent at its address determined pursuant to Section 14.10.  Unless
Agent determines that any applicable condition specified in Article V has not
been satisfied, Agent will make the funds so received from Banks available to
Borrower by crediting a checking account maintained by Borrower with Agent.
Unless Agent receives notice from a Bank at Agent's address specified pursuant
to Section 14.10, no later than 4:00 p.m. (Atlanta, Georgia time) on the
Domestic Business Day of a Loan stating that such Bank will not make available
its ratable share of a Loan, Agent shall be entitled to assume that such Bank
will make available its ratable share of the Loan and, in reliance on such
assumption, Agent may (but shall not be obligated to) make such Bank's ratable
share of the Loan available to Borrower for the account of such Bank.  If Agent
makes such Bank's ratable share of the Loan available to Borrower as provided
above, and if such Bank  does not in fact make its ratable share of such Loan
available on such day, Agent shall be entitled to recover such Bank's ratable
share of the Loan from such Bank or Borrower (and for such purpose shall be
entitled to charge such amount to any account of any Borrower maintained with
Agent), together with interest thereon for each day during the period from the
date of such Loan until such sum shall be paid in full at a rate per annum equal
to the rate at which Agent determines that it obtained (or could have obtained)
overnight federal funds to cover such amount for each such day during such
period, provided that (i) any such payment by Borrower of such Bank's ratable
        --------                                                             
share of a Loan and interest thereon shall be without prejudice to any rights
that Borrower may have against such Bank, and (ii) until such Bank has paid its
ratable share of such Loan, together with interest pursuant to the foregoing, it
will have no interest in or rights with respect to such Loan for any purpose
hereunder.  If Agent determines not to exercise its option to advance funds for
the account of such Bank, it shall forthwith notify Borrower of such
determination.

          (d) If any Bank makes a new Loan hereunder on a day on which Borrower
is to repay all or any part of an outstanding Loan from such Bank, such Bank
shall apply the proceeds of its new Loan to make such repayment as a Refunding
Loan, and only an amount equal to the difference (if any) between the amount
being borrowed and the amount of such Refunding Loan shall be made available by
such Bank to Agent as provided in paragraph (c) of this Section 2.04, or
remitted by Borrower to Agent as provided in Section 2.11, as the case may be.

                                      -25-
<PAGE>
 
          (e) All Advance Requests shall specify (i) the date, (ii) the
amount,(iii) the interest rate election, (iv) such other information called for
in the form of the Advance Request, and (v) in the case of the election of a
LIBOR Rate Loan, the Interest Period for such Loan.  Any such notice which Agent
believes in good faith to have been given by a duly authorized agent of Borrower
shall be deemed given by Borrower.  Notwithstanding any provision of this
Agreement to the contrary, if, after Agent's receipt of Borrower's Advance
Request for a LIBOR Rate Loan, Agent determines in good faith that it is not
possible to determine the applicable LIBOR Rate or the LIBOR Rate shall not
cover the actual cost to Banks of obtaining United States dollar deposits in the
Interbank Eurodollar Market plus the Applicable Margin, then Agent shall
promptly notify Borrower and Banks of such determination, and the Loan subject
to the notice shall be a Base Rate Loan.

     2.05  AUTOMATIC CONVERSION.  All LIBOR Rate Loans not paid in full on or
           --------------------                                                
before the last day of the Interest Period therefor shall automatically convert
to Base Rate Loans upon the expiration of the Interest Period.

     2.06  INTEREST PAYMENTS ON LOANS.  Accrued and unpaid interest on the
           --------------------------                                       
unpaid principal amount of each Loan shall be due and payable on the last day of
the Interest Period applicable thereto and, if earlier, on the date three (3)
months after the date the Loan was made.  Interest payable on the Loans shall be
computed on the basis of a hypothetical year of 360 days for the actual number
of days elapsed.

     2.07  MATURITY.  The entire unpaid principal amount of the Loans,
           --------                                                     
together with all accrued and unpaid interest thereon, shall be due and payable
on the Expiration Date.

     2.08  NOTES.  (a)  The Loans made by each Bank shall be evidenced by a
           -----                                                             
Note made by Borrower payable to the order of such Bank in an amount equal to
the original principal amount of such Bank's Commitment.

          (b) Upon receipt of each Bank's Note pursuant to Section 4.07, Agent
shall deliver such Note to such Bank.  Each Bank shall record, and prior to any
transfer of its Note shall endorse, on the schedules forming a part thereof,
appropriate notations to evidence the date, amount and maturity of, and
effective interest rate for, each Loan made by the Bank with respect thereto,
and such schedules of each such Bank's Note shall constitute rebuttable
presumptive evidence of the respective principal amounts owing and unpaid on
such Bank's Note; provided that the failure of any Bank to make, or any error in
                  --------                                                      
making, any such recordation or endorsement shall not affect the obligation of
Borrower hereunder or under the Notes or the 

                                      -26-
<PAGE>
 
ability of any Bank to assign its Note. Each Bank is hereby irrevocably
authorized by Borrower so to endorse its Note and to attach to and make a part
of any Note a continuation of any such schedule as and when required.

          (c) In the event of loss, theft, destruction, total or partial
obliteration, mutilation or inappropriate cancellation of a Note, Borrower will
execute and deliver, in lieu thereof, a replacement Note identical in form and
substance to such Note and dated as of the date of such Note.

     2.09  USE OF LOAN PROCEEDS.  The proceeds of the Loans will be used by
           --------------------                                              
Borrower and, through advances made by Borrower to or investments made by
Borrower in (to the extent permitted in accordance with Section 9.12) any other
Subsidiary or Non-Consolidated Venture, by any such Subsidiary or Non-
Consolidated Venture, to satisfy Borrower's obligations to Banks' Agent (as
defined in the 1996 Credit Agreement) under the 1996 Credit Agreement and
otherwise solely to finance their general business needs, including, without
limitation, their operating and administrative expenses, interest and principal
payments on loans, the acquisition, development and maintenance of their
properties, the payment of taxes, insurance and commissions relating to their
properties and business operations, the payment of distributions by Borrower to
its partners and of dividends by Weeks Corporation to its shareholders, and to
make loans to unrelated entities for the purpose of constructing buildings and
related improvements upon real property owned by such unrelated entities,
provided that the Person making such loan shall have obtained a recorded first
- --------                                                                      
mortgage security interest in the real property under development and, further,
that the Person shall manage the construction of the building and related
improvements and that Weeks Corporation or any such Consolidated Entity or Non-
Consolidated Subsidiary shall have a contractual right to acquire the improved
real property prior to the making of the loan.

     2.10  PREPAYMENT OF LOANS.  (a)  Borrower may, upon at least five (5)
            -------------------                                              
Euro-Dollar Business Days' notice to Agent, prepay any LIBOR Rate Loan in whole
at any time, or from time to time in part in amounts aggregating at least
$5,000,000 or any larger integral multiple of $1,000,000, by paying the
principal amount to be prepaid together with accrued interest thereon to the
date of prepayment, plus, if such prepayment is not made on the last day of the
applicable Interest Period, the amount of compensation, if any, determined to be
due pursuant to paragraph (e) of this Section 2.10, and the fee due pursuant to
Section 13.03.  Each such optional prepayment shall be applied to prepay ratably
the LIBOR Rate Loans made by Banks.

          (b) Borrower may, upon at least one (1) Domestic Business Day's notice
to Agent, prepay any Base Rate Loan in 

                                      -27-
<PAGE>
 
whole at any time, or from time to time in part in amounts aggregating at least
$1,000,000 or any larger integral multiple of $500,000, by paying the principal
amount to be prepaid together with accrued interest thereon to the date of
prepayment. Each such optional prepayment shall be applied to prepay ratably the
Base Rate Loans made by Banks.

          (c) On each date on which the Facility Amount is reduced by Borrower
pursuant to Section 2.16, Borrower shall prepay such principal amount of the
Loans (either pursuant to the foregoing clause (a) or clause (b) of this Section
2.10 or both), if any (together with interest thereon and such compensation as
may be due in accordance with clause (e) of this Section 2.10), as may be
necessary so that, after such prepayment, the aggregate principal amount of the
Loans do not exceed the Facility Amount, calculated as of such date after the
Facility Amount has been so reduced.

          (d) Upon receipt of a notice of prepayment pursuant to this Section
2.10, Agent shall promptly notify each Bank of the contents thereof and of such
Bank's ratable share of such prepayment.  Such notice, once received by Agent,
shall not thereafter be revocable by Borrower.

          (e) Upon prepayment of all or part of the outstanding principal amount
of any LIBOR Rate Loan prior to the last day of the Interest Period therefor,
including any such prepayment made as a result of an acceleration of the
maturity of the Loans upon a Default, Borrower shall pay to Agent, to be applied
ratably to each Bank's pro rata portion of such LIBOR Rate Loan, compensation
with respect to such prepayment equal to Banks' Breakage Costs with respect
thereto.

     2.11  GENERAL PROVISIONS AS TO PAYMENTS.  (a)  Borrower shall make each
            ---------------------------------                                  
payment of principal of, and interest on, the Loans and of fees hereunder, not
later than 1:00 p.m. (Atlanta, Georgia time) on the day when due, in federal or
other funds immediately available in Atlanta, Georgia, to Agent at its address
referred to in Section 14.10.  All such payments of principal of, and interest
on, the Loans and of fees hereunder shall be credited to the account of Borrower
on the day so received by Agent, if received before 1:00 p.m. (Atlanta, Georgia
time), or on the next Domestic Business Day, if so received after 1:00 p.m.
(Atlanta, Georgia time).  Agent will promptly distribute to each Bank its
ratable share of each such payment received by Agent for the account of Banks.
If Agent fails to distribute to any Bank its ratable share of any such payment
on the day received, if received not later than 1:00 p.m. (Atlanta, Georgia
time) on such day, or on the next Domestic Business Day, if received after 1:00
p.m.  (Atlanta, Georgia time) on such day, such Bank shall be entitled to
recover such Bank's ratable share of such payment from Agent, together with
interest thereon for each day during 

                                      -28-
<PAGE>
 
the period from the date of distribution of such Bank's ratable share of such
payment shall have become due until such distribution shall be made, at a rate
per annum equal to the rate at which Agent determines that it obtained (or could
have obtained) overnight federal funds in such amount for each such day during
such period.

          (b) Whenever any payment of principal of, or interest on, Base Rate
Loans or fees hereunder shall be due on a day which is not a Domestic Business
Day, the date for payment thereof shall be extended to the next succeeding
Domestic Business Day.  Whenever any payment of principal of or interest on,
LIBOR Rate Loans shall be due on a day which is not a Euro-Dollar Business Day,
the date for payment thereof shall be extended to the next succeeding Euro-
Dollar Business Day, unless such Euro-Dollar Business Day falls in another
calendar month, in which case the date for payment thereof shall be the next
preceding Euro-Dollar Business Day.

          (c) All payments of principal, interest and fees and all other amounts
to be made by Borrower pursuant to this Agreement with respect to any Loan or
fee relating thereto shall be paid without deduction for, and free from, any
taxes, imposts, levies, deductions, or withholdings now or hereafter imposed by
any governmental authority or by any taxing authority thereof or therein,
excluding in the case of each Bank or Agent (i) any taxes imposed by the United
States or any political subdivision thereof on the effectively connected net
income of it or its Lending Office or any franchise taxes imposed by such
jurisdiction, (ii) taxes imposed on the net income of, or franchise taxes
imposed upon, it by the jurisdiction under the laws of which it is organized or
by any political subdivision thereof, (iii) taxes imposed on the net income of
its Lending Office, and franchise taxes imposed on it, by the jurisdiction of
its Lending Office, or any political subdivision thereof, (iv) any taxes imposed
on it by Section 884(a) of the Internal Revenue Code of 1986, as amended (and
any successor statute to Section 884(a)), and (v) any United States withholding
tax payable with respect to any payments to it under the laws (including,
without limitation, any treaty, ruling, judicial or administrative determination
or regulation) in effect on the Initial Date (as hereinafter defined), but not
                                                                       -------
excluding any United States withholding tax payable or increased as a result of
- ---------                                                                      
any change in any law, treaty, ruling, judicial or administrative determination
or regulation, or interpretation thereof occurring after said Initial Date (all
such non-excluded taxes, levies, imposts, deductions and withholdings
hereinafter referred to as "TAXES").  For purposes hereof, the term "INITIAL
                            -----                                    -------
DATE" shall mean, in the case of each Bank or Agent party hereto on the date
- ----                                                                        
hereof, the date of this Agreement, and in the case of each other Bank or Agent,
the effective date of the Assignment and Acceptance, or other instrument
pursuant to which it became a Bank or other party hereunder.

                                      -29-
<PAGE>
 
     In the event that Borrower is required by applicable law to make any such
withholding or deduction of Taxes with respect to any Loan or fee or other
amount, Borrower shall pay such deduction or withholding to the applicable
taxing authority, shall promptly furnish to the Affected Bank in respect of
which such deduction or withholding is made all receipts and other documents
evidencing such payment, and shall pay to the Affected Bank additional amounts
as may be necessary in order that the amount received by the Affected Bank after
the required withholding or other payment shall equal the amount it would have
received had no such withholding or other payment been made.  If in such event
no withholding or deduction of Taxes are payable in respect to any Loan or fee
relating thereto, Borrower shall furnish the Affected Bank, at its written
request, a certificate from each applicable taxing authority or an opinion of
counsel reasonably acceptable to it, in either case stating that such payments
are exempt from or not subject to withholding or deduction of Taxes.  If
Borrower fails to provide such original or certified copy of a receipt
evidencing payment of Taxes or certificate(s) or opinion of counsel described in
the preceding sentence, Borrower hereby agrees to compensate the Affected Bank
for, and indemnify it with respect to, the tax consequences of Borrower's
failure to provide evidence of tax payments or tax exemption; provided, however,
                                                              --------  ------- 
that Borrower shall not be obligated to indemnify any party for penalties,
additions to tax, interest or expenses associated with the payment of Taxes if
the Affected Bank's liability for such Taxes has arisen as a result of the
violation by it of the terms of this Agreement.  Such compensation or
indemnification payment shall be made within 30 days from the date such Affected
Bank makes written request therefor.  Any such request shall be made within 90
days after the date on which such payment of Taxes was made.  Each such request
shall be accompanied by a copy of the statement from the taxing authority
demanding payment by the Affected Bank of such Taxes or by a certificate from
the Affected Bank which certificate shall set forth in reasonable detail the
basis for any additional amount payable to such party under this Section 2.11(c)
(together with reasonable evidence of payment of such Taxes).

     Each Bank or Agent which is not organized under the laws of the United
States or any state thereof agrees, as soon as practicable after receipt by it
of a request by Borrower to do so, to file all appropriate forms and take other
appropriate action to obtain a certificate or other appropriate document from
the appropriate governmental authority in the jurisdiction imposing the relevant
Taxes, establishing that it is entitled to receive payments of principal and
interest under this Agreement and the Notes without deduction and free from
withholding of any Taxes imposed by such jurisdiction; provided that if it is
                                                       --------              

                                      -30-
<PAGE>
 
unable, for any reason, to establish such exemption, or to file such forms and,
in any event, during such period of time as such request for exemption is
pending, Borrower shall nonetheless remain obligated under the terms of the
immediately preceding paragraph.

     In the event any Affected Bank receives a refund of any Taxes paid by
Borrower pursuant to this Section 2.11(c), it will pay to Borrower the amount of
such refund promptly upon receipt thereof; provided that if at any time
                                           --------                    
thereafter it is required to return such refund, Borrower shall promptly repay
to it the amount of such refund.

     Without prejudice to the survival of any other agreement of Borrower
hereunder, the agreements and obligations of Borrower, Banks and Agent contained
in this Section 2.11(c) shall be applicable with respect to any Transferee, and
any calculations required by such provisions (i) shall be made based upon the
circumstances of such Transferee, and (ii) constitute a continuing agreement and
shall survive the termination of this Agreement and the payment in full or
cancellation of the Notes.

     2.12  DEFAULT RATE OF INTEREST.  If a Default shall occur under this
           ------------------------                                        
Agreement, interest shall accrue on the unpaid principal amount of the Loans
from and after the date of such occurrence through and including the date on
which such Default shall have been cured at a rate of interest equal to the
highest rate otherwise applicable to any such Loan plus an additional two
percent (2.00%) per annum (200 basis points).

     2.13  FEES.  In consideration of Banks' establishing the Revolving
           ----                                                          
Credit Facility, Borrower shall pay Agent, for the ratable benefit of Banks, the
following fees:

          (a)  ORIGINATION FEE.  An Origination Fee, which shall be due and
               ---------------                                               
payable on the effective date of this Agreement, equal to 0.20% of the amount by
which the initial Facility Amount under this Agreement ($225,000,000) exceeds
the initial Facility Amount (as defined in the 1996 Credit Agreement) under the
1996 Credit Agreement ($175,000,000), which shall be pro rated among Banks on
the basis of the dollar amount, if any, by which each Bank's Commitment under
this Agreement exceeds such Bank's Commitment (as defined in the 1996 Credit
Agreement), if any, under the 1996 Credit Agreement, provided that the
                                                     --------         
Commitment (as defined in the 1996 Credit Agreement) of any Bank which had no
Commitment under the 1996 Credit Agreement shall be deemed to be $0 for the
purposes of such pro ration.

          (b)  EXTENSION FEES.  An Extension Fee, which shall be computed as
               --------------                                                 
set forth below, for each extension of the Expiration Date after December 31,
2000, which shall be due and payable on each Extension Date, and which shall be
deemed fully earned 

                                      -31-
<PAGE>
 
and nonrefundable when paid. The Extension Fee shall be computed by (a)
multiplying .10% by the Facility Amount in effect on the due date thereof, (b)
dividing the product so obtained by 360, and (c) multiplying the quotient so
obtained by the actual number of days in the year of the extension.

          (c)  FACILITY FEE.  A Facility Fee, which shall be computed as set
               ------------                                                   
forth below, for each calendar year during which this Agreement is in effect,
which shall be due and payable in advance on the effective date of this
Agreement and on the first (1st) Business Day of each calendar year thereafter
commencing 1999, and which shall be deemed fully earned and nonrefundable when
paid.  The Facility Fee shall be computed by  (a) multiplying the percentage
determined as set forth below by the Facility Amount in effect on the due date
thereof, (b) dividing the product so obtained by 360, and (c) multiplying the
quotient so obtained, in the case of the Facility Fee due and payable on the
effective date of this Agreement, by the actual number of days in the period
commencing on such effective date and ending on December 31, 1998, and in the
case of each subsequent Facility Fee, the actual number of days in the calendar
year for which the Facility Fee is due.  For purposes of the foregoing, the
percentage shall be determined by reference to the Debt Rating Table and shall
be based on the Debt Rating, if any, as determined by Agent, in effect as of
such day if such day is a Performance Pricing Determination Date, or otherwise
as of the Performance Pricing Determination Date immediately preceding such day;
provided that if there is no Debt Rating in effect on such day, the percentage
- --------                                                                      
shall be the same as that set forth in the applicable Performance Pricing Level
V of the Debt Rating Table.

     2.14  INCREASED COSTS; ILLEGALITY; CAPITAL ADEQUACY. (a) If any Bank
           ---------------------------------------------                   
should suffer any increased cost in connection with any Loan, as a result of any
change subsequent to the date hereof causing the imposition or increase of any
reserve, insurance, tax or assessment requirement (other than a tax assessable
on the Bank's overall net income or gross receipts) or the compliance with any
guidelines or requests from any governmental authority issued subsequent to the
date hereof (whether or not having the force of law), such Bank shall, upon
becoming aware of such increased costs, certify to Borrower the amount thereof
(and such certification shall be deemed prima facie correct), whereupon Borrower
                                        ----- -----                             
shall have the option either to:  (i) repay in full the Notes and request Banks
to terminate this Agreement; or (ii) continue to borrow from Banks under the
terms of this Agreement and pay such Bank on subsequent interest payment dates
such additional amounts as will compensate such Bank from the date of receipt of
certification, for such increased costs.

          (b) In the event that the introduction of or any change subsequent to
the date hereof in any applicable law, rule or regulation or in the
interpretation or administration thereof 

                                      -32-

or compliance by any Bank with any request or directive (whether or not having
the force of law) of any governmental authority shall, in the determination of
such Bank (which determination shall be made in good faith and shall be deemed
prima facie correct) make it unlawful or impractical for such Bank to make, fund
- ----- -----
or maintain any Loan, such Bank shall promptly, upon becoming aware of such
event, notify Borrower thereof, whereupon Borrower shall, upon receipt of such
notice, pay in full such amounts as will compensate such Bank for any losses
(not including lost profits) or expenses which such Bank shall have sustained or
incurred as a result of such event (and the determination of which by such Bank
shall be deemed prima facie correct, as certified by such Bank).
                ----- -----

          (c) If, after the date hereof, the adoption of any applicable law,
rule or regulation regarding capital adequacy, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the administration thereof, or compliance
by any Bank with any request or directive regarding capital adequacy (whether or
not having the force of law) of any such authority, central bank or comparable
agency, affects the amount of capital required or expected to be maintained by
such Bank or any person or entity in Control of such Bank and such Bank
determines that the amount of said capital is increased by or based upon such
Bank's obligations hereunder, then such Bank will promptly notify Borrower
thereof, and from time to time, upon demand by such Bank, Borrower shall pay to
such Bank such additional amount or amounts as will compensate such Bank in
light of such circumstances, to the extent that such Bank reasonably determines
such increase in capital is allocable to its obligations hereunder.

     2.15  CALCULATION OF COMPENSATION TO BANKS; REQUIRED TRANSFER BY BANKS.
           ----------------------------------------------------------------   

          (a) Any Bank or Agent requiring compensation pursuant to Section
2.11(c) or subparagraphs (a), (b) and (c) of  Section 2.14 shall deliver to
Borrower a certificate setting forth in reasonable detail the calculations of
any additional amounts required in order to compensate such Bank or Agent under
Section 2.11(c) or subparagraphs (a), (b) and (c) of  Section 2.14.  In
determining any such amounts, the Affected Bank may use any reasonable averaging
and attribution method, provided such Affected Bank shall use such methods in
                        --------                                             
good faith, and such methods shall be in accordance with those generally used by
such Bank for this purpose for other comparable credit facilities.

          (b) Any Bank or other Person entitled to claim any additional amounts
payable pursuant to Section 2.11 or Section 2.14 shall endeavor in good faith
(consistent with its internal policy  and legal and regulatory restrictions) to
retain the 

                                      -33-
<PAGE>
 
jurisdiction of its Lending Office or change the jurisdiction of its Lending
Office, as the case may be, if such retention or change would avoid the need
for, or reduce the amount of, any such additional amounts which may thereafter
accrue and such retention or change would not, in its reasonable judgment, be
otherwise materially disadvantageous to it, provided that nothing contained in
                                            --------
this Section 2.15(b) shall be deemed to require any Bank or other Person to
retain, maintain or establish an office in any jurisdiction for the sole purpose
of avoiding the need for, or reducing the amount of, any such additional amounts
which may thereafter accrue.

          (c) Notwithstanding the foregoing, in the event Borrower is required
to pay any Bank or Agent amounts pursuant to Section 2.11 or Section 2.14 and
the designation of a different Lending Office pursuant to Section 2.15(b) will
not avoid the need for compensation to such Bank or Agent, as the case may be
(an "AFFECTED BANK"), Borrower may give notice to such Affected Bank (with
     -------------                                                        
copies to Agent) that it wishes to seek one or more assignees (which may be one
or more of the Banks) to assume the Commitment of such Affected Bank and to
purchase its outstanding Loans and Note; provided, that if there is more than
                                         --------                            
one Affected Bank that has requested substantially and proportionally equal
compensation hereunder, Borrower shall elect to seek an assignee to assume the
Commitments of all such Affected Banks.  Each Affected Bank agrees to sell its
Commitment, Loans, Note and interest in this Agreement in accordance with
Section 14.03(c) to any such assignee for an amount equal to the sum of the
outstanding unpaid principal of and accrued interest on such Loans and Note,
plus all other fees and amounts (including, without limitation, any compensation
due to such Affected Banks under Section 2.11 or Section 2.14 calculated, in
each case, to the date such Loans, Note and interest are purchased.  Upon such
sale or prepayment, each such Affected Bank shall have no further commitment or
other obligation to Borrower hereunder or under any Note, except as provided in
Section 2.11(c).

     2.16  FACILITY AMOUNT REDUCTION OR TERMINATION.  Borrower shall have the
           ----------------------------------------                            
option, from time to time, to reduce the Facility Amount by $10,000,000 or any
greater integral multiple of $5,000,000, by (a) giving written notice of its
election to exercise such option to Agent no later than three (3) Domestic
Business Days before the date the reduction is to be effective, and (b) giving
such notice of, and making such, prepayment, if any, as is required by the
provisions of Section 2.10 on account of such reduction of the Facility Amount.
In no event shall Borrower, as a result of any such election, be entitled to a
refund of any fees paid to Agent or any Bank hereunder or be entitled
thereafter, without the written consent of Agent and all Banks, to a restoration
of the amount, or any part thereof, by which the Facility Amount shall have been
reduced.  Upon receipt of any such written notice, Agent shall deliver a copy of
the same to each Bank.

                                   THE AGENT
                                   ---------

     3.01  APPOINTMENT; POWERS AND IMMUNITIES.  Each Bank hereby irrevocably
           ----------------------------------                                 
appoints and authorizes Agent to act as its agent hereunder and under the other
Loan Documents with such powers as are specifically delegated to Agent by the
terms hereof and thereof, together with such other powers as are reasonably
incidental thereto.  Agent: (a) shall have no duties or responsibilities except
as expressly set forth in this Agreement and the other Loan Documents, and shall
not by reason of this Agreement or any other Loan Document be a trustee for any
Bank; (b) shall not be responsible to Banks for any recitals, statements,
representations or warranties contained in this Agreement or any other Loan
Document, or in any certificate or other document referred to or provided for
in, or received by any Bank under, this Agreement or any other Loan Document, or
for the validity, effectiveness, genuineness, enforceability or sufficiency of
this Agreement or any other Loan Document or any other document referred to or
provided for herein or therein or for any failure by Borrower to perform any of
its obligations hereunder or thereunder; (c) shall not be required to initiate
or conduct any litigation or collection proceedings hereunder or under any other
Loan Document except to the extent requested by the Required Banks, and then
only on terms and conditions satisfactory to Agent, and (d) shall not be
responsible for any action taken or omitted to be taken by it hereunder or under
any other Loan Document or any other document or instrument referred to or
provided for herein or therein or in connection herewith or therewith, except
for its own gross negligence or wilful misconduct.  Agent may employ agents and
attorneys-in-fact and shall not be responsible for the negligence or misconduct
of any such agents or attorneys-in-fact selected by it with reasonable care.
The provisions of this Article III are solely for the benefit of Agent and
Banks, and Borrower shall not have any rights as a third party beneficiary of
any of the provisions hereof.  In performing its functions and duties under this
Agreement and under the other Loan Documents, Agent shall act solely as agent of
Banks and does not assume and shall not be deemed to have assumed any obligation
towards or relationship of agency or trust with or for Borrower.  The duties of
Agent shall be ministerial and administrative in nature, and Agent shall not
have by reason of this Agreement or any other Loan Document a fiduciary
relationship in respect of any Bank.  Agent shall administer the Loans and the
Loan Documents with the same degree of care as that customarily employed by
Agent in the administration of similar credit facilities for its own account.

     3.02  RELIANCE BY AGENT.  Agent shall be entitled to rely 
           -----------------

upon any certification, notice or other communication (including any thereof by
telephone, telecopier, telegram or cable) believed by it to be genuine and
correct and to have been signed or sent by or on behalf of the proper person or
persons, and upon advice and statements of legal counsel, independent
accountants or other experts selected by Agent. As to any matters not expressly
provided for by this Agreement or any other Loan Document, Agent shall in all
cases be fully protected in acting, or in refraining from acting, hereunder and
thereunder in accordance with instructions signed by the Required Banks, and
such instructions of the Required Banks in any action taken or failure to act
pursuant thereto shall be binding on all Banks.

     3.03  DEFAULTS.  Agent shall not be deemed to have knowledge of the
           --------                                                       
occurrence of a Default (other than the nonpayment of principal of or interest
on the Loans) unless Agent has received notice from a Bank or Borrower
specifying such Default and stating that such notice is a "Notice of Default."
In the event that Agent receives such a notice of the occurrence of a Default,
Agent shall give prompt notice thereof to Banks.  Agent shall give each Bank
prompt notice of each nonpayment of principal of or interest on the Loans
whether or not it has received any notice of the occurrence of such nonpayment.
Agent shall (subject to Article XII) take such action hereunder with respect to
such Default as shall be directed by the Required Banks, provided that, unless
                                                         --------             
and until Agent shall have received such directions, Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default as it shall deem advisable in the best interests of the Banks.

     3.04  RIGHTS OF AGENT AS A BANK.  With respect to the Loans made by
           -------------------------                                      
Wachovia in its capacity as a Bank hereunder, Wachovia in its capacity as a Bank
hereunder shall have the same rights and powers hereunder as any other Bank and
may exercise the same as though Wachovia were not acting as Agent, and the term
"BANK" or "BANKS" shall, unless the context otherwise indicates, include
 ----      -----                                                        
Wachovia in its individual capacity.  Wachovia may (without having to account
therefor to any Bank) accept deposits from, lend money to, and generally engage
in any kind of banking, trust or other business with Borrower (and any of
Borrower's Affiliates) as if Wachovia were not acting as Agent, and Wachovia and
any Affiliate of Wachovia may accept fees and other consideration from Borrower
(in addition to any agency fees and arrangement fees heretofore agreed to
between Borrower and Agent) for services in connection with this Agreement or
any other Loan Document or otherwise without having to account for the same to
Banks.

     3.05  INDEMNIFICATION.  Each Bank severally agrees to indemnify Agent,
           ---------------                                                   
to the extent Agent shall not have been reimbursed by Borrower, ratably in
accordance with its 

                                      -36-
<PAGE>
 
Commitment, for any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses (including, without
limitation, counsel fees and disbursements) or disbursements of any kind and
nature whatsoever which may be imposed on, incurred by or asserted against Agent
in any way relating to or arising out of this Agreement or any other Loan
Document or any other documents contemplated by or referred to herein or therein
or the transactions contemplated hereby or thereby (excluding, unless a Default
has occurred and is continuing, the normal administrative costs and expenses
incident to the performance of its agency duties hereunder) or the enforcement
of any of the terms hereof or thereof or any such other documents; provided that
                                                                   --------
no Bank shall be liable for any of the foregoing to the extent they arise from
the gross negligence or wilful misconduct of Agent. If any indemnity furnished
to Agent for any purpose shall, in the opinion of Agent, be insufficient or
become impaired, Agent may call for additional indemnity and cease, or not
commence, to do the acts indemnified against until such additional indemnity is
furnished.

     3.06  CONSEQUENTIAL DAMAGES.  AGENT SHALL NOT BE RESPONSIBLE OR LIABLE
           ---------------------                                             
TO ANY BANK, BORROWER OR ANY OTHER PERSON OR ENTITY FOR ANY PUNITIVE, EXEMPLARY
OR CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF THIS AGREEMENT, THE
OTHER LOAN DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

     3.07  PAYEE OF NOTE TREATED AS OWNER.  Agent may deem and treat the
           ------------------------------                                 
payee of any Note as the owner thereof for all purposes hereof unless and until
a written notice of the assignment or transfer thereof shall have been filed
with Agent and the provisions of Section 14.03(c) have been satisfied.  Any
requests, authority or consent of any person who at the time of making such
request or giving such authority or consent is the holder of any Note shall be
conclusive and binding on any subsequent holder, Transferee or Assignee of that
or of any Note or Notes issued in exchange therefor or replacement thereof.

     3.08  NONRELIANCE ON AGENT AND OTHER BANKS.  Each Bank agrees that it
           ------------------------------------                             
has, independently and without reliance on Agent or any other Bank, and based on
such documents and information as it has deemed appropriate, made its own credit
analysis of Borrower and decision to enter into this Agreement and that it will,
independently and without reliance upon Agent or any other Bank, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own analysis and decisions in taking or not taking action
under this Agreement or any of the other Loan Documents.  Agent shall not be
required to keep itself (or any Bank) informed as to the performance or
observance by Borrower of this Agreement or any of the other Loan Documents or
any other document referred to or provided for herein or therein or to inspect
the properties or books of Borrower or any other Person.  Except for notices,
reports and 

                                      -37-
<PAGE>
 
other documents and information expressly required to be furnished to Banks by
Agent hereunder or under the other Loan Documents, Agent shall not have any duty
or responsibility to provide any Bank with any credit or other information
concerning the affairs, financial condition or business of Borrower or any other
Person (or any of their Affiliates) which may come into the possession of Agent;
provided that Agent shall make available to any Bank, upon such Bank's request,
- --------
(a) copies of Agent's records with respect to all sums received or expended by
Agent in connection with the Loans and the Loan Documents, and (b) information
as to the amount of the then outstanding Loans.

     3.09  FAILURE TO ACT.  Except for action expressly required of Agent
           --------------                                                  
hereunder or under the other Loan Documents, Agent shall in all cases be fully
justified in failing or refusing to act hereunder and thereunder unless it shall
receive further assurances to its satisfaction by Banks of their indemnification
obligations under Section 3.05  against any and all liability and expense which
may be incurred by Agent by reason of taking, continuing to take, or failing to
take any such action.

     3.10  RESIGNATION OR REMOVAL OF AGENT.  Subject to the appointment and
           -------------------------------                                   
acceptance of a successor Agent as provided below, Agent may resign at any time
by giving notice thereof to Banks and Borrower, and Agent may be removed at any
time with or without cause by the Required Banks.  Upon any such resignation or
removal, Required Banks shall have the right to appoint a successor Agent,
subject to the approval of Borrower, which approval shall not be unreasonably
withheld or delayed; provided, however, that no such approval of Borrower shall
                     --------                                                  
be required if a Default is in existence.  If no successor Agent shall have been
so appointed by the Required Banks and shall have accepted such appointment
within thirty (30) days after the retiring Agent's notice of resignation or the
Required Banks' removal of the retiring Agent, then the retiring Agent may, on
behalf of Banks, appoint a successor Agent, subject to the approval of Borrower,
which approval shall not be unreasonably withheld or delayed; provided, however,
                                                              --------          
that no such approval of Borrower shall be required if a Default is in
existence.  Any successor Agent shall be a bank which has a combined capital and
surplus of at least $500,000,000.  Upon the acceptance of any appointment as
Agent hereunder by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Agent, and the retiring Agent shall be discharged from its
duties and obligations hereunder.  After any retiring Agent's resignation or
removal hereunder as Agent, the provisions of this Article III shall continue in
effect for its benefit in respect of any actions taken or omitted to be taken by
it while it was acting as the Agent hereunder.

     3.11  DIRECTIONS TO AGENT.  Whenever a provision of this 
           -------------------

Agreement provides that the giving, making or taking, as the case may be, of a
consent, approval, instruction, direction, acceptance, request or other action
by the Required Banks is required as a condition to the right or duty of Weeks
Corporation or Borrower or Agent to take or refrain from taking any action or to
the existence of any status or condition, and Agent shall have notified all
Banks of the action, status or condition for which such consent, approval,
instruction, direction, acceptance, request or other action is required, such
consent, approval, instruction, direction, acceptance, request or other action
may be, at the option of Agent, deemed given, made or taken, as the case may be,
by each Bank, unless such Bank shall have given Agent contrary instructions
within seven (7) Domestic Business Days after its receipt of such notice from
Agent. Notwithstanding the foregoing, Agent reserves the right to refrain from
acting on any matter which requires the consent, approval, direction,
instruction, acceptance, request or other action of one or more Banks unless and
until Agent shall have actually received the same from such party or parties as
provided for herein.

aggregate amount of all principal and interest owing with respect to the Note
held by such other Bank, the Bank receiving such proportionately greater payment

such other Banks, and such other adjustments shall be made, as may be required

from each other Bank shall be rescinded and such other Bank shall repay to the
purchasing Bank, as the case may be, the purchase price of such participation to

ratable share (according to the proportion of (a) the amount of such other
Bank's required repayment to (b) the total amount so recovered from the
purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered.  Borrower agrees,
to the fullest extent it may effectively do so under applicable law, that any
holder of a participation in a Note, whether or not acquired pursuant to the
foregoing arrangements, may exercise rights of setoff or counterclaim and other
rights with respect to such participation as fully as if such holder of a
participation were a direct creditor of Borrower in the amount of such
participation.

     13.04  INDEMNIFICATION.  At all times prior to and after the
            ---------------                                        
consummation of the transactions contemplated by this Agreement, Borrower and
Guarantors, jointly and severally, agree to hold harmless Banks, Agent, their
respective directors, officers, employees, agents, affiliates, successors and
assigns from and indemnify Banks, Agent, their respective directors, officers,
employees, agents, affiliates, successors and assigns, against all demands,
loss, damages, judgments, costs and expenses (including, without limitation,
reasonable attorneys' fees and expenses) actually incurred by any of the
foregoing, whether direct or indirect, as a result of or arising from or
relating to any claim for relief or cause of action made, brought, asserted or
threatened by any entity, asserting a claim for any legal or equitable remedy
against any person under any statute, or regulation or as a matter of law,
including, without limitation, any federal or state securities laws or under any
common law or equitable case or otherwise, arising from or in connection with
this Agreement, the other Loan Documents, any of the transactions contemplated
by this Agreement, or use of any proceeds of the Loans, except to the extent
such losses, damages, costs or expenses are due to the wilful misconduct or
gross negligence of, or breach of this Agreement by Agent, Banks, or any such
indemnitee.  At the request of Agent and any Bank, Borrower and Guarantors,
jointly and severally, will indemnify any assignee to whom any Bank transfers or
sells all or any portion of its interest in the Loans or participations therein
on terms substantially similar to the terms set forth above.  Agent and Banks
shall not be responsible or liable to any entity for consequential damages which

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

     14.01  CUMULATIVE RIGHTS; NON-WAIVER.  No delay or omission by Agent or
            -----------------------------
any Bank to exercise any right, power or remedy accruing upon any Default shall
exhaust or impair any such right, power or remedy or shall be construed to be a
waiver of any such Default, or acquiescence therein, and every right, power and
remedy given by this Agreement to Agent or Banks may be exercised from time to
time and as often as may be deemed expedient by Agent or any Bank.  No consent
or waiver, expressed or implied, by Agent or Banks to or of any Default shall be
deemed or construed to be a consent or waiver to or of any other Default.  No
delay, indulgence, departure, act or omission by Agent or Banks or any holder of
any of the Notes shall release, discharge, modify, change or otherwise affect
the original liability under the Notes or any other obligation of Borrower, or
any maker, surety or Guarantor, or preclude Agent or Banks from exercising any
right, privilege or power granted herein or alter 

                                      -65-

the security title, security interest or lien hereof. Agent or Banks may at any
time, without notice to or further consent from Borrower, surrender or
substitute any property or other security of any kind or nature whatsoever
securing the Obligations or release any Guarantor, and no such action will
release Borrower's obligations hereunder or alter the effect hereof. No right,
power or remedy conferred upon or reserved to Agent or Banks hereunder is
intended to be exclusive of any other right, power or remedy, but each and every
such right, power and remedy shall be cumulative and concurrent and shall be in
addition to any other right, power and remedy given hereunder or under the other
Loan Documents or now or hereafter existing at law, in equity or by statute.

     14.02  NO OBLIGATION TO THIRD PARTIES.  The Loan Documents are made
            ------------------------------                                
solely for the benefit of Guarantors, Borrower, Agent, each Bank and their
respective successors and assigns.  No other party whatsoever shall have
standing to bring any action as the result of the Loan Documents, or to assume
that Agent or any Bank will exercise any remedies provided herein, and no party
other than Agent and each Bank, their respective successors and assigns, shall
be deemed to be a beneficiary of any right or remedy provided by the Loan
Documents in favor of such parties, any and all of which may be freely waived in
whole or in part by Agent or Banks, in accordance with the terms and conditions
of this Agreement.  Nothing contained in this Section 14.02 is intended to
deprive Borrower of the benefit of any covenant by Agent and each Bank in favor
of Borrower contained in the Loan Documents.

     14.03  SUCCESSORS AND ASSIGNS.
            ----------------------   

          (a) The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and
assigns; provided that Borrower may not assign or otherwise transfer any of
         --------                                                          
their rights under this Agreement.

          (b) Any Bank may at any time sell to one or more persons (each a
                                                                          
"PARTICIPANT") participation interests in any Loan owing to such Bank any Note
- ------------                                                                  
held by such Bank, any Commitment hereunder or any other interest of such Bank
hereunder.  In the event of any such sale by a Bank of a participation interest
to a Participant, such Bank's obligations under this Agreement shall remain
unchanged, such Bank shall remain solely responsible for the performance
thereof, such Bank shall remain the holder of any such Note for all purposes
under this Agreement, and Borrower and Agent shall continue to deal solely and
directly with such Bank in connection with such Bank's rights and obligations
under this Agreement.  In no event shall a Bank that sells a participation be
obligated to the Participant to take or refrain from taking any action
hereunder, except that 

                                      -66-
<PAGE>
 
such Bank may agree that it will not (except as provided below), without the
consent of the Participant, agree to (i) the change of any date fixed for the
payment of principal of or interest on the related Loan or Loans, (ii) the
change of the amount of any principal, interest or fees due on any date fixed
for the payment thereof with respect to the related Loan or Loans, (iii) the
change of the principal of the related Loan or Loans, (iv) any change in the
rate at which either interest is payable thereon or (if the Participant is
entitled to any part thereof) fee is payable hereunder from the rate at which
the Participant is entitled to receive interest or fee (as the case may be) in
respect of such participation, (v) the release or substitution of all or any
substantial part of the collateral (if any) held as security for the Loans, or
(vi) the release of any Guaranty given to support payment of the Loans. Each
Bank selling a participation interest in any Loan, Note, Commitment or other
interest under this Agreement shall, within ten (10) Domestic Business Days of
such sale, provide Borrower and Agent with written notification stating that
such sale has occurred and identifying the Participant and the interest
purchased by such Participant.

          (c) Any Bank may at any time assign to one or more banks or financial
institutions (each an "ASSIGNEE") all or a proportionate part of its rights and
                       --------                                                
obligations under this Agreement, the Notes and the other Loan Documents, and
such Assignee shall assume all such rights and obligations, pursuant to an
Assignment and Acceptance, executed by such Assignee, such transferor Bank and
Agent, provided that (i) no interest may be sold by a Bank pursuant to this
       --------                                                            
paragraph (c) unless the Assignee shall agree to assume ratably equivalent
portions of the transferor Bank's Commitment, (ii) no interest may be sold by a
Bank pursuant to this paragraph (c) without the written consent of Agent, which
consent shall not be unreasonably withheld, (iii) if a Bank is assigning only a
portion of its Commitment, then the amount of the Commitment being assigned
(determined as of the effective date of the assignment) shall be in an amount
not less than $5,000,000, (iv) except during the continuance of a Default, no
interest may be sold by a Bank pursuant to this paragraph (c) to any Assignee
that is not then a Bank or an Affiliate of a Bank without the written consent of
Borrower, which consent shall not be unreasonably withheld, and (v) a Bank may
not, at any one time, have more than two (2) Assignees that are not Banks
immediately prior to such assignment.  Upon (A) execution of the Assignment and
Acceptance by such transferor Bank, such Assignee, Agent and Borrower, (B)
delivery of an executed copy of the Assignment and Acceptance to Borrower and
Agent, (C) payment by such Assignee to such transferor Bank of an amount equal
to the purchase price agreed between such transferor Bank and such Assignee, and
(D) payment by the transferor Bank of a processing and recordation fee of $2,500
to Agent, for its sole account, such Assignee shall for all purposes be a Bank
party to this Agreement and shall have all the rights and obligations of a Bank

                                      -67-
<PAGE>
 
under this Agreement to the same extent as if it were an original party hereto
with a Commitment as set forth in such instrument of assumption, and the
transferor Bank shall be released from its obligations hereunder to a
corresponding extent, and no further consent or action by Borrower, Banks or
Agent shall be required.  Upon the consummation of any transfer to an Assignee
pursuant to this paragraph (c), the transferor Bank, the Agent and Borrower
shall make appropriate arrangements so that, if required, a new Note is issued
to each of such Assignee and such transferor Bank.

          (d) Borrower authorizes Agent and each Bank to disclose to any
Participant or Assignee (each a "TRANSFEREE") and any prospective Transferee any
                                 ----------                                     
and all financial information in such Agent's or Bank's possession concerning
Borrower which has been delivered to such Agent or any Bank by Borrower or Agent
pursuant to this Agreement or which has been delivered to such Agent or any Bank
by Borrower in connection with such Agent's or such Bank's credit evaluation
prior to entering into this Agreement, provided that such Transferee or
                                       --------                        
prospective Transferee agrees to take reasonable actions to preserve the
confidentiality of any such confidential financial information disclosed.

          (e) Anything in this Section 14.03 to the contrary notwithstanding,
any Bank may assign and pledge all or any portion of the Loans and/or
obligations owing to it to any Federal Reserve Bank or the United States
Treasury as collateral security pursuant to Regulation A of the Board of
Governors of the Federal Reserve System and any Operating Circular issued by
such Federal Reserve Bank, provided that any payment in respect of such assigned
                           --------                                             
Loans and/or obligations made by Borrower to the assigning and/or pledging Bank
in accordance with the terms of this Agreement shall satisfy Borrower's
obligations hereunder in respect of such assigned Loans and/or obligations to
the extent of such payment.  No such assignment shall release the assigning
and/or pledging Bank from its obligations hereunder.

     14.04  GOVERNING LAW.  This Agreement is entered into in the State of
            -------------                                                   
Georgia, and the rights and obligations of the parties hereunder shall be
governed by, construed and interpreted in accordance with, the laws of the State
of Georgia.

     14.05  SURVIVAL OF OBLIGATIONS.  All representations, warranties and
            -----------------------                                        
covenants contained herein shall survive the Closings and the execution and
delivery of the Notes or any other documents contemplated hereby.

     14.06  ENTIRE AGREEMENT.  This Agreement (together with the provisions of
            ----------------                                                    
the Mandate Letter relating to fees payable to Agent) constitutes the entire
agreement of the parties hereto with respect to the subject matter hereof.

amendment or waiver is in writing and is signed ("signed," as used in this
Section 14.11, shall include, without limitation, signatures received by
facsimile transmission followed by a signed original)  by Borrower and the
Required Banks (and, if the rights or duties of Agent are affected thereby, by
Agent); provided that no such amendment or waiver shall, unless signed by all
        --------

its written agreement to waive or amend any of the provisions of this Agreement
except through Agent, and Agent shall be supplied by Weeks Corporation or

shall have been executed and delivered by the requisite percentage of Banks.
Borrower will not, directly or indirectly, pay or cause to be paid any
remuneration, whether by way of supplemental or additional interest, fee or
otherwise, to any Bank (in its capacity as such) as consideration for or as an
inducement to the entering into by such Bank of any waiver or amendment of any
of the terms and provisions of this Agreement, unless such remuneration is
concurrently paid, on the same terms, ratably to all Banks, provided that the

with any directive to disclose any such information so as to allow Weeks
Corporation or Borrower to effect any action seeking to prevent such disclosure.

     14.16 REPRESENTATIONS BY BANKS.  Each of Banks hereby represents that
           ------------------------                                         
(a) it is a commercial lender or financial institution which makes commercial
loans in the ordinary course of its business and that it will make its Loans or
Swing Loans, as the case may be, for its own account in the ordinary course of
such business; provided that, subject to Section 14.03, the disposition of the
               --------                                                       
Note or Notes held by it shall at all times be within its exclusive control, and
(b) no part of the funds to be used by it to fund the Loans constitutes or will
constitute (i) assets allocated to any separate account maintained by it in
which any employee benefit plan (or its related trust) has any interest nor (ii)
any other assets of any employee benefit plan.  

                                      -72-

As used in this Section, the terms "employee benefit plan" and "separate
account" shall have the respective meanings assigned to such terms in Section 3
of ERISA.

     14.17 MISCELLANEOUS.  The Loan Documents shall inure to the benefit of
           -------------                                                      
and be binding upon Borrower, Guarantors and Banks, Agent and their respective
heirs, executors, legal representatives, successors, successors-in-title and
assigns, subject to all restrictions on transfer herein or in the other Loan
Documents.  Neither the Loan Documents nor the proceeds of the Loans
contemplated by the Loan Documents may be assigned by Borrower without the prior
consent of Banks, which may be given or withheld at the discretion of Banks.
The Loan Documents may be discharged or terminated only by an instrument in
writing signed by the party against whom enforcement of such discharge or
termination is sought.  Nothing contained in the Loan Documents shall be
construed to create an agency, partnership or joint venture between Borrower and
Banks.  Wherever in the Loan Documents it is indicated that the approval,
consent or determination of Banks is to be given or made at the option or in the
discretion or judgment of Banks, then such Banks, or any of them, may grant or
withhold such approval or consent or make such determination without restriction
in its sole and absolute discretion.  The obligations of Borrower under this
Agreement and the Notes shall be subject to the limitation that payments of
interest shall not be required to the extent that receipt thereof would be
contrary to provisions of law applicable to Banks limiting rates of interest
which may be charged or collected by Banks.  In the event that any such payment
in excess of the maximum rate of interest allowed by applicable law is
inadvertently paid by Borrower or inadvertently received by the Banks, the
amount in excess of the maximum rate of interest allowed by applicable law shall
be credited as a payment of principal, unless Borrower shall notify the Banks in
writing that Borrower elects to have such excess sum returned to it forthwith.
All exhibits referred to in the Loan Documents are by such reference
incorporated into the Loan Documents as if fully set forth therein.

     IN WITNESS WHEREOF, the parties have caused this Agreement to be executed
and delivered in their names and on their behalf, and their seals to be affixed
and attested, all as of the day and year first above written.

     2.02  EXPIRATION; EXTENSION.  The Swing Credit Facility shall expire on
           ---------------------                                              
the Expiration Date, at which time the principal amount of all Swing Loans then
outstanding and all accrued but unpaid interest thereon shall be due and payable
in full.  The expiration of the Swing Credit Facility may be extended only in
accordance with the following:

          (a) Borrower may, in its sole discretion, give written notice to Swing
Bank, no sooner than 90 days and no later than 60 days before the then effective
Expiration Date, of its request to extend the expiration of the Swing Credit
Facility for a term ending 364 days after the then effective Expiration Date.
In the event that Swing Bank receives any such written request, Swing Bank may,
no later than 45 days before the then effective Expiration Date, give written
notice to Borrower of its determination, in its sole discretion, to make an
offer or not to make an offer to Borrower to extend the expiration of the Swing
Credit Facility for a term ending 364 days after the then effective Expiration
Date, and, if it shall have determined to make such an offer, the terms and
conditions of the offer and the amount of the extension fee which Swing Bank
shall require in consideration of the extension.

          (b) In the event that, no later than the then effective Expiration
Date, Borrower (i) accepts in writing the offer in accordance with those terms
and conditions set forth by Swing Bank in such written notice, (ii) pays Swing
Bank the extension fee required by Swing Bank, and (iii) executes and delivers
to Swing Bank an amendment to the Swing Line Master Note and such other
amendments, instruments or other documents required by Swing Bank as a condition
to the extension, all in form and substance acceptable to Swing Bank, the
Expiration Date shall thereupon be extended to the last day of the 364 day term
for which such extension shall have been offered.

          (c) In the event that (i) Borrower fails to give written notice to
Swing Bank, before 60 days before the then effective Expiration Date, of its
request to extend the expiration of the Swing Credit Facility, or (ii) Swing
Bank fails, before 45 days before the then effective Expiration Date, to respond
to such a written notice from Borrower, or (iii) Swing Bank gives written notice
to Borrower of its determination, in its sole discretion, not to make an offer
to Borrower to extend the Swing Credit Facility, or (iv) Swing Bank offers to
extend the Expiration Date, before 45 days before the then effective Expiration
Date but Borrower does not accept the offer, pay the stipulated extension fee,
and execute and deliver the documents required as a condition to the extension,
all on or before the then effective Expiration Date, the Swing Credit Facility
shall not be extended, and the principal amount of all Swing Loans then
outstanding and all accrued but unpaid interest thereon shall be due and payable
in full on such Expiration Date.

amount of the Swing Line Master Note at the LIBOR Rate.  Notwithstanding any
provision of this Agreement to the contrary, if Swing Bank determines in good
faith that it is not possible to determine the applicable LIBOR Rate or the
LIBOR Rate shall not cover the actual cost to Swing Bank of obtaining United
States dollar deposits in the Interbank Eurodollar Market plus the Applicable
Margin, then Swing Bank shall promptly notify Borrower, and the principal amount
of the Swing Line Master Note shall thereafter accrue interest at the Floating
Rate.

     2.04  NOTICE AND MANNER OF BORROWING.  (a)  Borrower shall give Swing
           ------------------------------                                   
Bank an Advance Request prior to 10:00 a.m. (Atlanta, Georgia time) on the
Banking Day on which the Swing Loan is to be made.

          (b) Upon receipt by Swing Bank of an Advance Request, such Advance
Request shall not thereafter be revocable by Borrower.

          (c) Unless Swing Bank determines that any applicable condition
specified in Article IV hereof has not been satisfied, Swing Bank will make the
funds available to Borrower by crediting a checking account maintained by
Borrower with Swing Bank.

          (d) All Advance Requests shall specify the date, amount, and such
other information called for in the form of the Advance Request.  Any such
notice which Swing Bank believes in good faith to have been given by a duly
authorized agent of Borrower shall be deemed given by Borrower.

     2.05  INTEREST PAYMENTS.  Beginning on the first (1st) day of the first
           -----------------                                                  
(1st) month after the initial Swing Loan is made and continuing on the first
(1st) day of each month thereafter so long as there is any principal amount or
accrued and unpaid interest outstanding under the Swing Line Master Note,
accrued and unpaid interest on the unpaid principal amount of the Swing Line
Master Note shall be due and payable.  Interest payable on the Swing Line Master
Note shall be computed on the basis of a hypothetical year of 360 days for the
actual number of days elapsed.

     2.06  MATURITY.  The entire unpaid principal amount of the Swing Line
           --------                                                        
Master Note, together with all accrued and unpaid interest thereon, shall be due
and payable on the Expiration Date.

     2.07  PERMITTED PREPAYMENT OF SWING LOANS.  All or part of the

without penalty or premium.

     2.08  DEFAULT RATE OF INTEREST.  If a Swing Line Default shall occur,
           ------------------------                                        
then, at the option of Swing Bank, interest shall accrue on the unpaid principal
amount of the Swing Loans from and after the date of such occurrence through and
including the date on which such Swing Line Default shall have been cured at
rates of interest equal to the rates otherwise applicable to such Swing Loans
plus an additional two percent (2.00%) per annum (200 basis points).

     2.09  FACILITY FEE.  A Facility Fee, which shall be computed as set forth
           ------------                                                         
below, shall be due and payable on the effective date of this Agreement and
shall be deemed fully earned and nonrefundable when paid.  The Facility Fee
shall be computed by  (a) multiplying the Swing Line Commitment by .10% (10
basis points), (b) dividing the product so obtained by 360, and (c) multiplying
the quotient so obtained by the actual number of days in the Swing Line
Commitment Period.

     2.10  USE OF PROCEEDS.  Proceeds of the Swing Loans shall be used
            ---------------                                               
solely for those purposes for which the proceeds of the Loans may be used as set
forth in Section 2.09 of the Syndicated Credit Agreement.

     2.11  INCREASED COSTS; ILLEGALITY; CAPITAL ADEQUACY.  (a) If Swing Bank
           ---------------------------------------------                      
should suffer any increased cost in connection with any Swing Loan, as a result
of any change subsequent to the date hereof causing the imposition or increase
of any reserve, insurance, tax or assessment requirement (other than a tax

contained in the Swing Loan Documents shall be construed to create an agency,
partnership or joint venture between Borrower and Swing Bank. Wherever in the
Swing Loan Documents it is indicated that the approval, consent or determination
of Swing Bank is to be given or made at the option or in the discretion or
judgment of Swing Bank without reference to a standard of reasonableness, then
Swing Bank may grant or withhold such approval or consent or make such
determination without restriction in its sole and absolute discretion. The
obligations of Borrower under this Agreement and the Swing Line Master Note
shall be subject to the limitation that payments of interest shall not be
required to the extent that receipt thereof would be contrary to provisions of
law applicable to Swing Bank limiting rates of interest which may be charged or
collected by Swing Bank. In the event that any such payment in excess of the
maximum rate of interest allowed by applicable law is inadvertently paid by
Borrower or inadvertently received by Swing Bank, the amount in excess of the
maximum rate of interest allowed by applicable law shall be credited as a
payment of principal, unless Borrower shall notify Swing Bank in writing that
the Borrower elects to have such excess sum returned to it forthwith. All
exhibits referred to in the Swing Loan Documents are by such reference
incorporated into the Swing Loan Documents as if fully set forth therein.

     IN WITNESS WHEREOF, the parties have caused this Agreement to be executed
and delivered in their names and on their behalf, and their seals to be affixed
and attested, all as of the day and year first above written.

                                 AGREEMENT
                                 ---------

     In consideration of the circumstances referred to in the Recitals, the
consummation of the transactions effected pursuant to the Transaction Documents,
the mutual covenants and agreements contained herein, and other good and
valuable consideration, the receipt, adequacy 

                                      -2-
<PAGE>
 
and sufficiency of which are hereby acknowledged, the parties hereto, intending
to be legally bound, hereby agree as follows:

     1.  Admission.  The Contributors are hereby admitted to the Partnership as
         ---------                                                             
Limited Partners, effective as of the date hereof, and each of the Contributors
hereby agrees to be bound by the Partnership Agreement, including, but not
limited to, the transfer restrictions contained in Article IX thereof.

     2.  Capital Contributions.  The Contributors are agreed to have made, as of
         ---------------------                                                  
the date hereof, the Capital Contributions set forth on Exhibit B hereto.  The
agreed to gross fair market values of any property other than money contributed
by each of the Contributors, which shall be such property's initial Gross Asset
Value, are shown on Exhibit B.

     3.  Initial Partnership Units; Rights.
         --------------------------------- 

          (a) The Partnership Units attributable to the Partnership Interests of
     the Contributors, effective upon their admission as Limited Partners at the
     date hereof, are as set forth on Exhibit B hereto, and the Partnership
     Agreement is hereby amended to reflect the Contributors' having such
     Partnership Units.

          (b) The Partnership does hereby grant to each of the Contributors, and
     each of them does hereby accept, the right, but not the obligation (herein
     such rights being sometimes referred to as the "Rights"), to require the
     Partnership to redeem all or a portion of the Partnership Units issued to
     them pursuant to the Transaction Documents, on the terms and subject to the
     conditions and restrictions contained in Exhibit D hereto.  The Rights are
     governed solely by this Amendment and Exhibit D hereto, and none of the
     Contributors shall have any rights with respect to the "Rights" provided
     for in Section 11.1 and Exhibit B-1 to the Partnership Agreement.  The
     Rights granted hereunder may be exercised by any one or more of the
     Contributors, on the terms and subject to the 

                                      -3-
<PAGE>
 
     conditions and restrictions contained in Exhibit D hereto, upon delivery to

     Conversion Exercise Notice shall be irrevocable, subject to compliance by
     the General Partner and the Partnership with the terms of the Rights.

         -----------------------------                                          
the Contributors as Limited Partners at the date hereof, the Percentage
Interests of the Contributors have been reflected on Exhibit C hereto, and the
Partnership Agreement is hereby amended accordingly.

     5.  Future Contributions.  The parties acknowledge that, pursuant to and
         --------------------                                                
subject to the terms and conditions of the Transaction Documents, the

such additional Capital Contribution, the General Partner shall supplement this
Amendment by executing and attaching hereto supplements to Exhibits B and C
(which shall be captioned "Exhibit B-1," "Exhibit B-2," "Exhibit C-1," "Exhibit
C-2," and so on and shall identify the Capital Contribution to which each
relates) that will, respectively, reflect (to the extent determinable at such
time) the Capital Contribution made by the Contributors at that time, the
initial Gross Asset Value of any property other than money included in such
Capital Contribution, the additional Partnership Units attributable to the
Partnership Interest associated with such Capital Contribution, and the
resulting restated Percentage Interests of all of the Partners.  Such
supplements shall be in accordance with the terms of the Transaction Documents.
The Partnership Agreement shall be deemed to be amended as reflected in each
such supplement to this Amendment.

         --------------------------                                            
the Partnership Agreement, including, without limitation, Section 6.2 thereof,
the Contributors agree that the distribution of Net Operating Cash Flow made for
the calendar quarter in which the Partnership Units are issued, by reason of
each Capital Contribution made pursuant to the 

                                      -4-
<PAGE>
 
Transaction Documents shall be equal to the amount of Net Operating Cash Flow
otherwise distributable with respect to such Partnership Units under the terms
of the Partnership Agreement, multiplied by a fraction, the numerator of which
is the number of calendar days beginning on the date of issuance of the
Partnership Units and ending on the last day of such calendar quarter and the
denominator of which is the total number of days in the calendar quarter in
which the Partnership Units are issued.

     7.  Tax Considerations.
         ------------------ 

          (a) During the five-year period commencing on the date hereof, the
General Partner agrees that in the event it elects to cause the Partnership to
sell or otherwise convey any of the properties contributed to the Partnership
pursuant to this Amendment (each, a "Contributed Property"), the General Partner
will structure any such sale or conveyance of a Contributed Property as a tax-
deferred like-kind exchange under Section 1031 of the Internal Revenue Code, as
amended (the "Code"), to the extent such sale or conveyance would result in the
recognition of gain for federal income tax purposes by one or more of the
Contributors; provided, however, that, so long as the General Partner and the
Partnership comply with the terms and provisions of subparagraph (c) below, the
foregoing limitation shall not apply to the Company or the Partnership and shall
not be binding on any successor in interest to the Company or the Partnership if
the Company or the Partnership (i) agrees to sell all or substantially all of
its assets (collectively, a "Bulk Sale") or (ii) agrees to any merger,
consolidation, reorganization, liquidation or similar transaction (collectively,
a "Merger").

          (b) During the period between the fifth (5th) anniversary of the date
hereof and the tenth (10th) anniversary of the date hereof, the General Partner
agrees that in the event it elects to cause the Partnership to sell or otherwise
convey any Contributed Property, the Partnership hereby agrees to provide
reasonable advance notice to the Contributors of any such sale or other
conveyance and, together with the Contributors, to use commercially reasonable,
good faith efforts to structure any such sale or conveyance of a Contributed
Property in a manner 

                                      -5-
<PAGE>
 
which the Contributors believe will avoid any substantial adverse federal income
tax consequences to Contributors resulting from such transaction; provided,
however, that, so long as the General Partner and the Partnership comply with
the terms and provisions of subparagraph (c) below, the foregoing limitation
shall not apply to the Company or the Partnership and shall not be binding on
any successor in interest to the Company or the Partnership if the Company or
the Partnership (i) agrees to a Bulk Sale or (ii) agrees to a Merger. If, after
such commercially reasonable, good faith efforts as provided in the immediately
preceding sentence, the General Partner determines in good faith, after taking
into consideration the objectives of both the Partnership and the Contributors,
that it is not in the best interest of the Partnership to structure such
transaction in a manner which the Contributors believe will achieve the
objective of avoiding any substantial adverse federal income tax consequences to
the Contributors resulting from such transaction, the General Partner may cause
the Partnership to consummate such transaction, without the consent of the
Contributors, it being acknowledged, however that in no event shall this
sentence or such consummation without the consent of the Contributors be deemed
a waiver or release by the Contributors of any rights or remedies available to
them for any failure by the Partnership to consider in a commercially
reasonable, good faith manner Contributors' tax objectives in structuring the
transaction as described above. Notwithstanding the foregoing, the Partnership
expressly acknowledges and agrees that in respect of any proposed sale of the
Contributed Property or any portion thereof during the period between the fifth
(5th) anniversary of the date hereof and the tenth (10th) anniversary of the
date hereof, that is not incident to a Bulk Sale or Merger: (x) the Partnership
shall reserve with its prospective purchaser the right to consummate the sale by
means of a tax-deferred exchange under Section 1031 of the Code; (y) the
Partnership shall reserve with its prospective purchaser the right to convey the
Contributed Property or applicable portion thereof to Contributors or any of the
persons or entities composing Contributors (the "Contributor Parties") prior to
the consummation of such sale so that such sale is consummated by the
Contributor Parties; and (z) at the option of the Contributor Parties, the
Partnership shall convey the Contributed Property or applicable portion thereof
to the Contributor Parties prior to the consummation of such sale, provided that
(A) the Contributor Parties pay to the Partnership an amount equal to the net

                                      -6-
<PAGE>
 
proceeds that would have been received by the Partnership in connection with
such sale (which payment may be made, at the sole option and election of the
Contributor Parties, by the payment of cash, by the tender of Partnership Units
for redemption at their fair market value at the date of tender, or any
combination of the foregoing in any proportion), and (B) the Contributor Parties
assume the obligations of the Partnership under the applicable documents to
consummate the sale. The Contributors shall be responsible for any Georgia
Realty Transfer Tax liability accruing to the Partnership as a result of the
transfers described in the immediately preceding sentence.

          (c) During the ten (10)-year period commencing on the date hereof, the
Partnership hereby agrees to provide reasonable advance notice to the
Contributors of any such proposed Bulk Sale or Merger and, together with the
Contributors, to use commercially reasonable, good faith efforts to structure
the transaction in a manner which the Contributors believe will avoid any
substantial adverse federal income tax consequences to the Contributors
resulting from such transaction.  If, after such commercially reasonable, good
faith efforts, the General Partner determines in good faith, after taking into
consideration the objectives of both the Partnership and the Contributors, that
it is not in the best interest of the Partnership to structure such transaction
in a manner which would achieve the objective of avoiding any substantial
adverse federal income tax consequences to the Contributors resulting from such
Bulk Sale or Merger, the General Partner may cause the Partnership to consummate
the Bulk Sale or Merger, without the consent of the Contributors, it being
acknowledged, however that in no event shall this sentence or such consummation
without the consent of the Contributors be deemed a waiver or release by the
Contributors of any rights or remedies available to them for any failure by the
Partnership to consider in a commercially reasonable, good faith manner
Contributors' tax objectives in structuring the proposed Bulk Sale or Merger as
described above.

          (d) Contributors acknowledge and agree that the Partnership and the
General Partner have made no representations or assurances to the Contributors
of the tax consequences of any course of action taken under paragraphs 7(a),
7(b) or 7(c) hereof at the request of 

                                      -7-
<PAGE>
 
Contributors designed to minimize or avoid substantial adverse financial federal
income tax consequences to Contributors and the Contributors bear the risk
thereof entirely.

     8.  Miscellaneous.  This Amendment shall be governed by and construed in
         -------------                                                       
conformity with the laws of the State of Georgia.  For the purposes of the
notice provisions of the Partnership Agreement, the address of each of the
Contributor is as set forth on the signature page hereof.  Except as expressly
amended hereby, the Partnership Agreement shall remain in full force and effect.
This Amendment and all the terms and provisions hereof shall be binding upon and
shall inure to the benefit of the parties, and their legal representatives,
heirs, successors and permitted assigns.

last day of such calendar quarter and the denominator of which is the total
number of days in the calendar quarter in which the Partnership Units are

     Contributor's representations as expressed herein; (iv) the Contributor has
     had an opportunity to discuss the Partnership's business, management and
     financial affairs with the Partnership's management and the opportunity to

     agreements of the Contributor referred to in this paragraph 8 are referred
     to collectively as the "Representations and Warranties."

          (d) General Partner Representations.  The General Partner represents
              -------------------------------                                 
     and warrants to the Contributor as follows:

     9.  Survival of Representations and Warranties.  All of the Representations
         ------------------------------------------                             
and Warranties shall survive the consummation of the transactions contemplated
by the Transaction Documents; provided, however, that no claim for a breach of
any Representation or Warranty may be maintained by the Partnership, the Company
or the General Partner unless the Partnership, the Company or the General
Partner shall have delivered a written notice ("Notice of Breach") specifying
the details of such claimed breach to the Contributor on or before the first

                                      -7-
<PAGE>
 
anniversary of the last issuance of Units pursuant to the Transaction Documents
(the "Survival Period").

     10.  Indemnification.
          --------------- 

          (a) The Contributor hereby indemnifies and holds harmless the
     Partnership, the Company and the General Partner against and from all
     liabilities, demands, claims, actions or causes of action, assessments,
     losses, fines, penalties, costs, damages and expenses (including, without
     limitation, reasonable attorneys' and accountants' fees and expenses
     actually incurred) sustained or incurred by the Partnership, the Company or
     the General Partner as a result of or arising out of any inaccuracy in or
     breach of a Representation or Warranty.

          (b) The Partnership, the Company and the General Partner shall not be
     entitled to indemnification hereunder unless a Notice of Breach has been
     delivered by the Partnership, the Company or the General Partner to the
     Contributor.

          (c) If a claim for indemnification is asserted by the Partnership, the
     Company or the General Partner against the Contributor, the Contributor
     shall have the right, at its own expense, to participate in the defense of
     any claim, action or proceeding asserted against the Partnership, the
     Company or the General Partner that resulted in the claim for
     indemnification, and if such right is exercised, the parties shall
     cooperate in the defense of such action or proceeding.

          (d) Indemnification of the Partnership, the Company and the General
     Partner pursuant to this paragraph 10 shall be the exclusive remedy of the
     Partnership, the Company and the General Partner for any breach of any
     Representation or Warranty contained in this contained in this Agreement.
     Nothing contained herein shall limit any remedy the Partnership (or any
     affiliate of the Partnership including, without limitation, any affiliate

                                      -8-
<PAGE>
 
     of the Partnership as determined with respect to the voting or economic
     control held by or in the Partnership) may have under the Transaction
     Documents, including, without limitation, the remedy of specific
     performance for any failure by the Contributor to contribute a property or
     otherwise limit any remedy the Partnership, the Company or the General
     Partner may have for any commission of fraud made by the Contributor.

     11.  Security and Remedies.
          --------------------- 

          (a) The Contributor hereby grants to the Partnership a lien upon and a
     continuing security interest in the Partnership Units issued to it pursuant
     to the Transaction Documents and the shares of Common Stock acquired by it
     upon exercise of Rights with respect to such Partnership Units (the
     "Collateral"), which shall be security for the indemnification obligations
     of the Contributor under paragraph 10 hereof.  Except as otherwise provided
     in this Amendment, the indemnification obligations of the Contributor
     hereunder with respect to breaches of Representations and Warranties shall
     be payable out of the Contributor's entire Collateral; provided, however,
     that the Contributor may satisfy all or any part of such indemnification
     obligation of the Contributor in cash if the Contributor so elects.  Any
     Transfer by the Contributor of its Collateral shall be subject to the lien
     and security interest granted hereby.

          (b) In the event the General Partner asserts that the Contributor has
     an indemnification obligation to the Partnership, the Company or the
     General Partner under paragraph 10 hereof, the General Partner shall
     deliver written notice (the "Indemnification Notice") to the Contributor
     describing in reasonable detail the circumstances giving rise to such
     obligation and the amount thereof.  If, within thirty (30) days after the
     receipt of an Indemnification Notice, the Contributor delivers written
     notice to the General Partner indicating that the Contributor disputes the
     circumstances giving rise to or the amount of such claimed indemnification

                                      -9-
<PAGE>
 
     obligation, the General Partner may submit such matter for binding
     arbitration in accordance with the provisions of Article XIV of the
     Partnership Agreement by delivering a Demand Notice to the Contributor
     pursuant to such Article XIV.  If, after receiving timely notice of a
     dispute hereunder from the Contributor, the General Partner fails to so
     submit the matter for arbitration within twenty (20) days after receipt of
     such notice from the Contributor, then the Contributor shall be relieved of
     the claimed indemnification obligation described in the Indemnification
     Notice.  In the event the Contributor (i) receives an Indemnification
     Notice and fails to timely deliver notice to the General Partner of its
     dispute as to the indemnification obligation and fails to make payment
     within thirty (30) days after delivery of an Indemnification Notice or (ii)
     has an indemnification obligation to the Partnership or the General Partner
     under paragraph 10 hereof as determined pursuant to Article XIV of the
     Partnership Agreement, and does not satisfy such obligation within ten (10)
     days after the decision rendered in the arbitration, then, in either event,
     the Partnership shall have any and all remedies of a secured creditor under
     the Uniform Commercial Code, and, in addition thereto, at the election of
     the Partnership, the Partnership shall, to the extent permitted by law, be
     deemed, without the payment of any further consideration or the taking of
     any further action required by the Contributor, to have acquired from the
     Contributor such portion of the Collateral as shall be equal in value
     (based, in the case of Partnership Units, on the Current Per Share Market
     Price as computed as of the date immediately preceding such deemed
     acquisition of the number of shares of Common Stock for which such
     Partnership Units could be redeemed if the General Partner assumed the
     redemption obligation and elected to pay the Redemption Price (as defined
     in Exhibit D) in shares of Common Stock (assuming the ownership limits in
     the Articles of Incorporation would not prohibit the issuance of any such
     shares of Common Stock to the Contributors), and, in the case of shares of
     Common Stock, on the Current Per Share Common Stock Price computed as of
     the date immediately preceding such deemed acquisition) to the amount
     recoverable from the Contributor under paragraph 10 hereof.  In the event
     the Partnership shall have acquired from the Contributor any Collateral
     pursuant to this paragraph 11, the General Partner shall deliver written

                                      -10-
<PAGE>
 
     notice to the Contributor within ten (10) days thereafter identifying the
     specific Collateral acquired and, if such Collateral consists of
     Partnership Units, the Percentage Interests of the Contributor following
     such acquisition.  Unless and until the Partnership shall have acquired
     from the Contributor any Collateral pursuant to this paragraph 11, the
     Contributor shall retain all rights with respect to the Collateral not
     expressly limited herein or in the Partnership Agreement, including,
     without limitation, rights to distributions provided for in the Partnership
     Agreement and rights to dividends on shares of Common Stock.  The
     Contributor hereby agrees to take any and all actions and to execute and
     deliver any and all documents or instruments necessary to perfect the
     security interest created by this Amendment, including delivering the
     certificates representing the Partnership Units or shares of Common Stock
     to the General Partner.

          (c) On the first day immediately following the expiration of the
     Survival Period as defined in paragraph 9 hereof (or, if a Notice of Breach
     has been delivered to the Contributor prior to such date, then on the first
     day immediately following the resolution of such Notice of Breach) the
     Contributor will be relieved of the restrictions on transferability
     provided for by this Amendment (except that the transfer restrictions
     contained in the Partnership Agreement shall continue) and the security
     interest in the Collateral shall terminate without further action, and the
     Partnership, at the request of the Contributor, shall promptly execute and
     deliver any document or instrument reasonably requested by the Contributor
     to evidence such termination.

     12.  Recourse.  Notwithstanding anything contained in this Amendment or in
          --------                                                             
the Partnership Agreement to the contrary, the recourse of the General Partner,
the Company or the Partnership under paragraph 10 hereof with respect to
breaches of Representations and Warranties of the Contributor shall not be
limited to the Contributor's Collateral.

     13.  Restriction on Transfer.  In connection with the security interests
          -----------------------                                            
granted by the Contributor under paragraph 11 hereof, the Contributor agrees

                                      -11-
<PAGE>
 
that any shares of Common Stock and any portion of the Contributor's Partnership
Interests included in the Collateral shall not be Transferred without the
consent of the General Partner; provided, however, that the Contributor may
Transfer all or any portion of such shares of Common Stock or Partnership
Interests to an Affiliate of such person (so long as such Affiliate remains an
Affiliate of such person), subject to the prior security interest granted in
paragraph 11 hereof and to the restrictions contained in Article IX of the
Partnership Agreement. Upon exercise of the Rights with respect to any
Partnership Units included in the Contributor's Collateral, the Partnership, in
perfection of the security interest herein granted, shall retain the
certificate(s) representing the portion of the Common Stock issued upon such
exercise that is included in such Collateral.  If any portion of the Partnership
Interests of the Contributor included in the Contributor's Collateral is
represented by certificates, the Partnership shall retain such certificates in
perfection of the security interest herein granted.  On the first day
immediately following the expiration of the Survival Period as defined in
paragraph 9 hereof (or, if a Notice of Breach has been delivered to the
Contributor prior to such date, then on the first day immediately following the
resolution of such Notice of Breach) the Contributor will be relieved of the
restrictions on transferability provided for by this paragraph 13 without
further action, and the Partnership, at the request of the Contributor, shall
promptly execute and deliver any document or instrument reasonably requested by
the Contributor to evidence such termination.

     14.  Miscellaneous.  This Amendment shall be governed by and construed in
          -------------                                                       
conformity with the laws of the State of Georgia.  For the purposes of the
notice provisions of the Partnership Agreement, the address of the Contributor
is as set forth on the signature page hereof.  Except as expressly amended
hereby, the Partnership Agreement shall remain in full force and effect.  This
Amendment and all the terms and provisions hereof shall be binding upon and
shall inure to the benefit of the parties, and their legal representatives,
heirs, successors and permitted assigns.

          (a) The Partnership Units attributable to the Partnership Interests of
     the Contributors, effective upon their admission as Limited Partners at the
     date hereof, are as set forth on Exhibit B hereto, and the Partnership
                                      ---------                            
     Agreement is hereby amended to reflect the Contributors' having such
     Partnership Units.

          (b) The Partnership does hereby grant to each of the Contributors, and
     each of them does hereby accept, the right, but not the obligation (herein
     such rights being sometimes referred to as the "Rights"), to require the
     Partnership to redeem all or a portion of the Partnership Units issued to
     them pursuant to the Transaction Documents, on the terms and subject to the
     conditions and restrictions contained in Exhibit D hereto.  The Rights are
                                              ---------                        
     governed solely by this Amendment and Exhibit D hereto, and none of the
                                           ---------                        
     Contributors shall have any rights with respect to the "Rights" provided

     contained in Exhibit D hereto, upon delivery to the Partnership 
                  ---------
<PAGE>
 
     of a Conversion Exercise Notice, in the form of Schedule 1 attached to
     Exhibit D, which notice shall specify the Partnership Units with respect to
     ---------
     which the Rights are being exercised. Once delivered, the Conversion
     Exercise Notice shall be irrevocable, subject to compliance by the General
     Partner and the Partnership with the terms of the Rights.

         -----------------------------                                          
the Contributors as Limited Partners at the date hereof, the Percentage
Interests of the Contributors have been reflected on Exhibit C hereto, and the
                                                     ---------                
Partnership Agreement is hereby amended accordingly.

     5.  Future Contributions.  The parties acknowledge that, pursuant to and
         --------------------                                                
subject to the terms and conditions of the Transaction Documents, the
Contributors may make additional Capital Contributions.  Concurrently with any
such additional Capital Contribution, the General Partner shall supplement this
Amendment by executing and attaching hereto supplements to Exhibits B and C
                                                           ----------------
(which shall be captioned "Exhibit B-1," "Exhibit B-2," "Exhibit C-1," "Exhibit
                           -----------    -----------    -----------    -------
C-2," and so on and shall identify the Capital Contribution to which each
- ---

time) the Capital Contribution made by the Contributors at that time, the
initial Gross Asset Value of any property other than money included in such
Capital Contribution, the additional Partnership Units attributable to the
Partnership Interest associated with such Capital Contribution, and the
resulting restated Percentage Interests of all of the Partners.  Such
supplements shall be in accordance with the terms of the Transaction Documents.
The Partnership Agreement shall be deemed to be amended as reflected in each
such supplement to this Amendment.

     6.  Adjustments to Partnership Units. The parties acknowledge that the
         --------------------------------                                  
Transaction Documents provide for adjustments to the Partnership Units of the
Contributors in certain circumstances, and further provide that the
Contributors' Partnership Interests and Units, and the resulting restated
Percentage Interests of all of the Partners, may not be capable of determination
at the time a Capital Contribution is made after the date hereof.  At the times
of adjustment and final determination provided for in the Transaction Documents,
the General Partner shall supplement this Amendment by executing and attaching
hereto either additional supplements to Exhibits B and C (in the form described
                                        ----------------                       
above), or amended and restated versions of prior supplements to Exhibits B and
                                                                 --------------
C, as applicable.  Such supplements shall be in accordance with the terms of the
- -                                                                               
Transaction Documents.  The Partnership Agreement shall be deemed to be amended
as reflected in each such supplement to this Amendment.

     7.  Proration of Distributions.  Notwithstanding any contrary provision of
         --------------------------                                            
the Partnership Agreement, including, without limitation, Section 6.2 thereof,
the Contributors agree that the distribution of Net Operating Cash Flow made for
the calendar quarter in which the Partnership Units are issued, by reason of
each Capital Contribution made pursuant to the Transaction Documents shall be
equal to the amount of Net Operating Cash Flow otherwise distributable with
respect to such Partnership Units under the terms of the Partnership Agreement,
multiplied by a fraction, the numerator of which is the number of calendar days
beginning on the date of issuance of the Partnership Units and ending on the
last day of such 
<PAGE>
 
calendar quarter and the denominator of which is the total number of days in the
calendar quarter in which the Partnership Units are issued.

     8.  Representations and Warranties.
         ------------------------------ 

          (a) Contributors' Representations.  The Contributors, jointly and
              -----------------------------                                
     severally, hereby reaffirm and make to each of the Partnership and the
     General Partner those representations and warranties contained in the
     Contribution Agreement identified in Exhibit A attached hereto.  In
     addition, the Contributors, jointly and severally, hereby represent and
     warrant to the Partnership and the General Partner that (i) each such
     Contributor is acquiring the Partnership Units for such Contributor's own
     account and not with a view to, or for sale in connection with, the
     "distribution," as such term is used in Section 2(11) of the Securities Act
     of 1933, as amended (the "Securities Act"), of any of the Partnership Units
     in violation of the Securities Act;  (ii) each such Contributor is an
     "accredited investor," as that term is defined in Rule 501(a) of Regulation
     D promulgated under the Securities Act; (iii) each such Contributor
     understands that the Partnership Units have not been registered under the
     Securities Act by reason of a specific exemption from the registration
     provisions of the Securities Act which depends upon, among other things,
     the nature of the investment intent and the accuracy of such Contributor's
     representations as expressed herein; (iv) each such Contributor has had an
     opportunity to discuss the Partnership's business, management and financial
     affairs with the Partnership's management and the opportunity to review the
     Partnership's financial records; (v) each such Contributor understands and
     acknowledges that no public market now exists for any of the Partnership
     Units and that there can be no assurance that a public market will ever
     exist for the Partnership Units; and (vi) each such Contributor has such
     knowledge and experience in financial and business matters, or has been
     adequately advised by such Contributor's financial representatives, that
     such Contributor is capable of evaluating the merits and risks of the
     purchase of the Partnership Units pursuant to this Agreement and of
     protecting such Contributor's interests in connection herewith.

          (b) No Liens.  The Contributors, jointly and severally, represent and
              --------                                                         
     warrant to the Partnership and the General Partner that at the date hereof
     none of the Partnership Units issued or issuable to the Contributors
     pursuant to the Transaction Documents, and none of the shares of Common
     Stock that may be acquired by the Contributors upon exercise of Rights, is
     subject to any Lien, other than the security interest created by paragraph
     11 hereof.

          (c) Definition.  All of the representations, warranties, covenants and
              ----------                                                        
     agreements of each of the Contributors referred to in this paragraph 8 are
     referred to collectively as the "Representations and Warranties."

          (d) General Partner Representations.  The General Partner represents
              -------------------------------                                 
     and warrants to each of the Contributors as follows:
<PAGE>
 
               (i) Organization.  The General Partner is duly incorporated,
                   ------------                                            
          validly existing and in good standing under the laws of the State of
          Georgia.

               (ii) Due Authorization; Binding Agreement.  The execution,
                    ------------------------------------                 
          delivery and performance of this Amendment by the General Partner have
          been duly and validly authorized by all necessary action of the
          General Partner and the Partnership.  This Amendment has been duly
          executed and delivered by the General Partner and constitutes a legal,
          valid and binding obligation of the General Partner and the
          Partnership, enforceable against the General Partner and the
          Partnership in accordance with the terms hereof.

               (iii)  Consents and Approvals.  No consent, waiver, approval or
                      ----------------------                                  
          authorization of, or filing, registration or qualification with, or
          notice to, any governmental unit or any other Person is required to be
          made, obtained or given by the General Partner in connection with the
          execution, delivery and performance of this Amendment, other than
          consents, waivers, approvals or authorizations that have been obtained
          prior to the date hereof.

               (iv) Partnership Units.  The Partnership Units  issued pursuant
                    -----------------                                         
          to the Transaction Documents are duly authorized and, when issued in
          accordance with the Transaction Documents, will be duly issued, fully
          paid and nonassessable and will be unencumbered except for the
          security interest created by paragraph 11 hereof.

     9.  Survival of Representations and Warranties.  All of the Representations
         ------------------------------------------                             
and Warranties shall survive the consummation of the transactions contemplated
by the Transaction Documents; provided, however, that no claim for a breach of
any Representation or Warranty may be maintained by the Partnership, the Company
or the General Partner unless the Partnership, the Company or the General
Partner shall have delivered a written notice ("Notice of Breach") specifying
the details of such claimed breach to the respective Contributor or before the
first anniversary of the last issuance of Units pursuant to the Transaction
Documents (the "Survival Period").

     10.  Indemnification.
          --------------- 

          (a) The Contributors, jointly and severally, indemnify and hold
     harmless the Partnership, the Company and the General Partner against and
     from all liabilities, demands, claims, actions or causes of action,
     assessments, losses, fines, penalties, costs, damages and expenses
     (including, without limitation, reasonable attorneys' and accountants' fees
     and expenses actually incurred) sustained or incurred by the Partnership,
     the Company or the General Partner as a result of or arising out of any
     inaccuracy in or breach of a Representation or Warranty.
<PAGE>
 
          (b) The Partnership, the Company and the General Partner shall not be
     entitled to indemnification hereunder unless a Notice of Breach has been
     delivered by the Partnership, the Company or the General Partner to the
     Contributors.

          (c) If a claim for indemnification is asserted by the Partnership, the
     Company or the General Partner against the Contributors, the Contributors
     shall have the right, at their own expense, to participate in the defense
     of any claim, action or proceeding asserted against the Partnership, the
     Company or the General Partner that resulted in the claim for
     indemnification, and if such right is exercised, the parties shall
     cooperate in the defense of such action or proceeding.

          (d) Indemnification of the Partnership, the Company and the General
     Partner pursuant to this paragraph 10 shall be the exclusive remedy of the
     Partnership, the Company and the General Partner for any breach of any
     Representation or Warranty contained in this contained in this Agreement.
     Nothing contained herein shall limit any remedy the Partnership (or any
     affiliate of the Partnership including, without limitation, any affiliate
     of the Partnership as determined with respect to the voting or economic
     control held by or in the Partnership) may have under the Transaction
     Documents, including, without limitation, the remedy of specific
     performance for any failure by the Contributor to contribute a property or
     otherwise limit any remedy the Partnership, the Company or the General
     Partner may have for any commission of fraud made by the Contributor.

     11.  Security and Remedies.
          --------------------- 

          (a) Each of the Contributors hereby grants to the Partnership a lien
     upon and a continuing security interest in the Partnership Units issued to
     each of them pursuant to the Transaction Documents and the shares of Common
     Stock acquired by each of them upon exercise of Rights with respect to such
     Partnership Units (the "Collateral"), which shall be security for the
     indemnification obligations of the Contributors under paragraph 10 hereof.
     Except as otherwise provided in this Amendment, the indemnification
     obligations of the Contributors hereunder with respect to breaches of
     Representations and Warranties shall be payable out of the Contributors
     entire Collateral; provided, however, that the Contributors may satisfy all
     or any part of such indemnification obligation of the Contributors in cash
     if the Contributors so elect.  Any Transfer by a Contributor of its
     Collateral shall be subject to the lien and security interest granted
     hereby.

          (b) In the event the General Partner asserts that the Contributors
     have an indemnification obligation to the Partnership, the Company or the
     General Partner under paragraph 10 hereof, the General Partner shall
     deliver written notice (the "Indemnification Notice") to the Contributors
     describing in reasonable detail the circumstances giving rise to such
     obligation and the amount thereof.  If, within thirty (30) days after the
     receipt of an Indemnification Notice, the Contributors deliver written
     notice to the General Partner indicating that the Contributors dispute the
     circumstances giving 
<PAGE>
 
     rise to or the amount of such claimed indemnification obligation, the
     General Partner may submit such matter for binding arbitration in
     accordance with the provisions of Article XIV of the Partnership Agreement
     by delivering a Demand Notice to the Contributors pursuant to such Article
     XIV. If, after receiving timely notice of a dispute hereunder from the
     Contributors, the General Partner fails to so submit the matter for
     arbitration within twenty (20) days after receipt of such notice from the
     Contributors, then the Contributors shall be relieved of the claimed
     indemnification obligation described in the Indemnification Notice. In the
     event the Contributors (i) receive an Indemnification Notice and fail to
     timely deliver notice to the General Partner of their dispute as to the
     indemnification obligation and fail to make payment within thirty (30) days
     after delivery of an Indemnification Notice or (ii) have an indemnification
     obligation to the Partnership or the General Partner under paragraph 10
     hereof as determined pursuant to Article XIV of the Partnership Agreement,
     and do not satisfy such obligation within ten (10) days after the decision
     rendered in the arbitration, then, in either event, the Partnership shall
     have any and all remedies of a secured creditor under the Uniform
     Commercial Code, and, in addition thereto, at the election of the
     Partnership, the Partnership shall, to the extent permitted by law, be
     deemed, without the payment of any further consideration or the taking of
     any further action required by the Contributors, to have acquired from the
     Contributors such portion of the Collateral as shall be equal in value
     (based, in the case of Partnership Units, on the Current Per Share Market
     Price as computed as of the date immediately preceding such deemed
     acquisition of the number of shares of Common Stock for which such
     Partnership Units could be redeemed if the General Partner assumed the
     redemption obligation and elected to pay the Redemption Price (as defined
     in Exhibit D) in shares of Common Stock (assuming the ownership
        ---------
     limits in the Articles of Incorporation would not prohibit the issuance of
     any such shares of Common Stock to the Contributors), and, in the case of
     shares of Common Stock, on the Current Per Share Common Stock Price
     computed as of the date immediately preceding such deemed acquisition) to
     the amount recoverable from the Contributors under paragraph 10 hereof. In
     the event the Partnership shall have acquired from the Contributors any
     Collateral pursuant to this paragraph 11, the General Partner shall deliver
     written notice to the Contributors within ten (10) days thereafter
     identifying the specific Collateral acquired and, if such Collateral
     consists of Partnership Units, the Percentage Interests of the Contributors
     following such acquisition. Unless and until the Partnership shall have
     acquired from the Contributors any Collateral pursuant to this paragraph
     11, the Contributor shall retain all rights with respect to the Collateral
     not expressly limited herein or in the Partnership Agreement, including,
     without limitation, rights to distributions provided for in the Partnership
     Agreement and rights to dividends on shares of Common Stock. Each
     Contributor hereby agrees to take any and all actions and to execute and
     deliver any and all documents or instruments necessary to perfect the
     security interest created by this Amendment, including delivering the
     certificates representing the Partnership Units or shares of Common Stock
     to the General Partner.

          (c) On the first day immediately following the expiration of the
     Survival Period as defined in paragraph 9 hereof (or, if a Notice of Breach
     has been delivered to 
<PAGE>
 
     the Contributors prior to such date, then on the first day immediately
     following the resolution of such Notice of Breach) the Contributors will be
     relieved of the restrictions on transferability provided for by this
     Amendment (except that the transfer restrictions contained in the
     Partnership Agreement shall continue) and the security interest in the
     Collateral shall terminate without further action, and the Partnership, at
     the request of the Contributors, shall promptly execute and deliver any
     document or instrument reasonably requested by the Contributors to evidence
     such termination.

     12.  Recourse.  Notwithstanding anything contained in this Amendment or in
          --------                                                             
the Partnership Agreement to the contrary, the recourse of the General Partner,
the Company or the Partnership under paragraph 10 hereof with respect to
breaches of Representations and Warranties of any Contributor shall not be
limited to such Contributor's Collateral.

     13.  Restriction on Transfer.  In connection with the security interests
          -----------------------                                            
granted by each Contributor under paragraph 11 hereof, each of the Contributors
agrees that any shares of Common Stock and any portion of such Contributor's
Partnership Interests included in the Collateral shall not be Transferred
without the consent of the General Partner; provided, however, that each of the
Contributors may Transfer all or any portion of such shares of Common Stock or
Partnership Interests to an Affiliate of such person (so long as such Affiliate
remains an Affiliate of such person), subject to the prior security interest
granted in paragraph 11 hereof and to the restrictions contained in Article IX
of the Partnership Agreement. Upon exercise of the Rights with respect to any
Partnership Units included in a Contributor's Collateral, the Partnership, in
perfection of the security interest herein granted, shall retain the
certificate(s) representing the portion of the Common Stock issued upon such
exercise that is included in such Collateral.  If any portion of the Partnership
Interests of a Contributor included in such Contributor's Collateral is
represented by certificates, the Partnership shall retain such certificates in
perfection of the security interest herein granted.  On the first day
immediately following the expiration of the Survival Period as defined in
paragraph 9 hereof (or, if a Notice of Breach has been delivered to the
Contributors prior to such date, then on the first day immediately following the
resolution of such Notice of Breach) the Contributors will be relieved of the
restrictions on transferability provided for by this paragraph 13 without
further action, and the Partnership, at the request of the Contributors, shall
promptly execute and deliver any document or instrument reasonably requested by
the Contributors to evidence such termination.

     14.  Miscellaneous.  This Amendment shall be governed by and construed in
          -------------                                                       
conformity with the laws of the State of Georgia.  For the purposes of the
notice provisions of the Partnership Agreement, the address of each of the
Contributor is as set forth on the signature page hereof.  Except as expressly
amended hereby, the Partnership Agreement shall remain in full force and effect.
This Amendment and all the terms and provisions hereof shall be binding upon and
shall inure to the benefit of the parties, and their legal representatives,
heirs, successors and permitted assigns.
