1.  General:

     The consolidated financial statements of ProLogis Trust ("ProLogis"),
formerly Security Capital Industrial Trust, as of June 30, 1998 and for the
three and six months ended June 30, 1998 and 1997 are unaudited, and pursuant to
the rules of the Securities and Exchange Commission, certain information and
footnote disclosures normally included in financial statements have been
omitted.  While management of ProLogis believes that the disclosures presented
are adequate, these interim consolidated financial statements should be read in
conjunction with ProLogis' December 31, 1997 audited consolidated financial
statements contained in ProLogis' 1997 Annual Report on Form 10-K.

     In the opinion of management, the accompanying unaudited consolidated
financial statements contain all adjustments, consisting of normal recurring
adjustments, necessary for a fair presentation of ProLogis' consolidated
financial position and results of operations for the interim periods.  The
results of operations for the three and six months ended June 30, 1998 and 1997
are not necessarily indicative of the results to be expected for the entire
year.

     The preparation of financial statements in conformity with generally
accepted accounting principles ("GAAP") requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period.  Actual results could differ from those estimates.


   Name Change

     On May 19, 1998, the Board of Trustees (the "Board") of ProLogis
announced plans to change the company's name from Security Capital Industrial
Trust to ProLogis Trust.  An amendment to the Declaration of Trust, which
changed the name effective July 1, 1998, was approved by ProLogis' shareholders
at the annual meeting on June 30, 1998.  The name change is intended to create
stronger name recognition among its customers as ProLogis expands globally.


   Comprehensive Income

     On January 1, 1998, ProLogis adopted Statement of Financial Accounting
Standards ("SFAS") No. 130, "Reporting Comprehensive Income" which establishes
standards for the reporting and display of comprehensive income and its
components.  The adoption of this standard did not have a significant impact on
the financial position, results of operations or financial statement disclosures
of ProLogis.  Other comprehensive income in the accompanying Statements of
Income and Comprehensive Income represents a net unrealized gain on foreign
currency translation adjustments. This unrealized gain has been recognized as a
component of shareholders' equity with no impact to net earnings.

   Per Common Share Data

     ProLogis adopted SFAS No. 128, "Earnings Per Share" in December 1997.  SFAS
No. 128 replaces the presentation of primary and fully diluted earnings per
share with a presentation of basic and diluted earnings per share.  The adoption
of SFAS No. 128 did not result in a restatement of previously reported earnings
per share data.

     The weighted-average number of common shares of beneficial interest, par
value $0.01 per share ("Common Shares"), outstanding during the year is used to
calculate basic earnings per Common Share.  Diluted earnings per Common Share
reflects the potential dilution that could occur if securities or other
contracts to issue Common Shares were exercised or converted into Common Shares
or resulted in the issuance of Common Shares that then shared in earnings.  See
Note 8.

   Accounting for Derivatives

     SFAS No. 133, "Accounting for Derivative Instruments and for Hedging
Activities" was issued on June 16, 1998. SFAS No. 133 is effective for fiscal
years beginning after June 15, 1999 and early adoption is allowed. SFAS No. 133
provides comprehensive guidelines for the recognition and measurement of
derivatives and hedging activities and, specifically, requires all derivatives
to be recorded on the balance sheet at fair value. Management is currently
evaluating the effects, if any, this pronouncement will have on its financial
position, results of operations and financial statement disclosures.

   Reclassifications

     Certain 1997 amounts have been reclassified to conform to the 1998
presentation.

     Capitalized preacquisition costs include $1.6 million and $3.6 million of
funds on deposit with title companies as of June 30, 1998 and December 31, 1997,
respectively, for property acquisitions.

     In addition to the June 30, 1998, construction payable accrual of $33.6
million, ProLogis had unfunded commitments on its contracts for developments
under construction totaling $248.2 million.

   ProLogis Development Services

     ProLogis Development Services Incorporated ("ProLogis Development
Services") develops corporate distribution facilities to meet customer
requirements or contracts on a fee basis to develop distribution facilities for
customers. ProLogis owns 100% of the preferred stock of ProLogis Development
Services and realizes substantially all economic benefits of its activities.
ProLogis advances mortgage loans to ProLogis Development Services to fund its
acquisition, development and construction activities. ProLogis accounts for
these loans as real estate investments, effectively consolidating the activities
of ProLogis Development Services.

     As of June 30, 1998, the outstanding balances of development and mortgage
loans made by ProLogis to ProLogis Development Services for the purchase of
distribution facilities and land for distribution facility development
aggregated $209.3 million.  The gains recognized on disposition of undepreciated
property by ProLogis Development Services and the fees generated by ProLogis
Development Services are reflected as other real estate income by ProLogis.

consulting company. On July 1, 1998, ProLogis Development Services increased its
ownership in the common stock in Insight to 23.1% by contributing an additional
$500,000. ProLogis Development Services is committed to investing an additional
$1,000,000 in Insight through July 1, 1999, which would bring its ownership
interest to 33.3%. This investment is accounted for on the cost method.

   ProLogis Logistics

     ProLogis owns 100% of the preferred stock and recognizes substantially all
economic benefits of the activities of ProLogis Logistics Services Incorporated
("ProLogis Logistics"). At June 30, 1998, ProLogis Logistics owned 100% of a
refrigerated distribution company, CS Integrated LLC ("CSI"). ProLogis Logistics
acquired a 60% interest in CSI on April 24, 1997 and increased its ownership to
77.1% during the remainder of 1997. On June 12, 1998, ProLogis Logistics
increased its ownership in CSI to 100% by purchasing the minority shareholder's
interest.

     On June 15, 1998, CSI acquired Rosenberger Cold Storage for $55.4 million.
With this acquisition, CSI owned or operated refrigerated distribution
facilities aggregating 96.0 million cubic feet at June 30, 1998.

     At June 30, 1998, ProLogis had a $141.0 million note receivable from
ProLogis Logistics. The note is unsecured, bears interest at 10% per annum and
matures on April 24, 2002. Interest payments on the note are due annually.

     ProLogis accounts for its investment in ProLogis Logistics on the equity
method. ProLogis recognized income (including interest income on the notes
receivable and a management fee payable from CSI) from its investment in
ProLogis Logistics of $1.5 million for the three months ended June 30, 1998 and
also for the three months ended June 30, 1997, and $2.5 million and $1.5 million
for the six months ended June 30, 1998 and 1997, respectively.

   Frigoscandia S.A.

     On January 16, 1998, ProLogis invested in 100% of the preferred stock of
Frigoscandia S.A., a Luxembourg company, which acquired a refrigerated
distribution company headquartered in Sweden for $400.3 million on the same
date. The acquired company, Frigoscandia AB, is 100% owned by Frigoscandia
Holding AB. Frigoscandia Holding AB is 100% owned by a wholly-owned subsidiary
of Frigoscandia S.A. At June 30, 1998, Frigoscandia AB, which operates in eight
European countries, owned 178.5 million cubic feet of refrigerated distribution
facilities and had an additional 4.3 million cubic feet of facilities under
development. The common stock of Frigoscandia S.A. is owned by a subsidiary of
Security Capital Group Incorporated ("Security Capital"), ProLogis' largest
shareholder. ProLogis recognizes substantially all economic benefits of the
activities of Frigoscandia S.A.

     At June 30, 1998, ProLogis had a $183.1 million note receivable from
Frigoscandia Holding AB. The unsecured note bears interest at 8% per annum and
is due on demand. Additionally, at June 30, 1998, ProLogis had a $30 million
mortgage note receivable from Frigoscandia Limited UK, a subsidiary of
Frigoscandia AB. The mortgage note receivable, which provides for interest at 7%
per annum and matures on March 20, 2018, is secured by refrigerated distribution
properties.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
                                        

     ProLogis accounts for its investment in Frigoscandia S.A. on the equity
method. ProLogis recognized a loss of $2.5 million and income of $0.7 million
for the three and six months periods ended June 30, 1998, respectively,
(including interest income on the mortgage note and note receivable) from its
investment in Frigoscandia S.A.

4.  Borrowings:

    Line of Credit

     At June 30, 1998, ProLogis had a $350 million unsecured revolving line of
credit agreement with NationsBank, N.A., ("NationsBank"), as agent for a bank
group. This agreement provides for interest at ProLogis' option, at either (a)
the greater of the federal funds rate plus 0.5% and the prime rate, or (b) LIBOR
plus 0.95% based upon ProLogis' senior debt ratings in effect at June 30, 1998.
At June 30, 1998, ProLogis was in compliance with all covenants contained in the
credit agreement. ProLogis had $197.0 million of borrowings outstanding on the
line of credit at June 30, 1998.

     On August 11, 1998, ProLogis entered into an amended and restated credit
agreement with NationsBank that provides for a $350 million unsecured revolving
line of credit. The new agreement, which replaces the credit agreement in effect
at June 30, 1998, provides for interest, at ProLogis' option, at either (a) the
greater of the federal funds rate plus 0.5% and the prime rate, or (b) LIBOR
plus 0.75% based upon ProLogis' current senior debt ratings. In addition,
ProLogis pays certain annual fees. Under a competitive bid option contained in
the new line of credit agreement, ProLogis may be able to borrow at a lower
interest rate spread over LIBOR, depending on market conditions. This option is
available on up to $100 million of borrowings. The line of credit matures on May
1, 2000 and may be extended annually for an additional year with the approval of
NationsBank and the other participating lenders. All borrowings under the line
of credit are subject to certain covenants, similar to those contained in the
previous line of credit agreement.

     In addition, ProLogis has a $25 million short-term unsecured discretionary
line of credit with NationsBank that matures on October 1, 1998. The rate of
interest and the maturity date of each advance on this line of credit are
determined by agreement between ProLogis and NationsBank at the time of each
advance. At June 30, 1998, there were $19.6 million of borrowings outstanding on
this credit facility.

    Long-term Debt Offering

     On July 20, 1998, ProLogis completed a $250 million offering of 7.05% debt
securities due July 15, 2006 (the "2006 Notes") with a coupon rate of 7.05%. The
securities were issued at a discount, resulting in a yield to maturity of 7.08%.
The 2006 Notes are direct, senior unsecured obligations of ProLogis and rank
equally with all other unsecured and unsubordinated indebtedness of ProLogis
from time to time outstanding. Interest on the 2006 Notes is payable
semiannually in arrears. The 2006 Notes are redeemable at any time at the option
of ProLogis, in whole or in part, at a redemption price equal to the principal
amount of the 2006 Notes being redeemed plus accrued interest thereon to the
redemption date plus a make-whole amount, if any. The 2006 Notes are governed by
the terms and provisions of the same indenture agreement applicable to ProLogis'
other debt securities. Net proceeds from the offering were approximately $247.6
million, net of underwriters' commissions and other costs.

     Interest Expense

     For the six months ended June 30, 1998 and 1997, interest expense on all
borrowings was $34.0 million and $24.6 million, respectively, which was net of
capitalized interest of $8.9 million and $8.5 million, respectively. The total
interest paid in cash was $41.7 million and $28.5 million for the six months
ended June 30, 1998 and 1997, respectively.


5.  Minority Interest:

     Minority interest represents limited partners' interests in five real
estate partnerships controlled by ProLogis (Red Mountain Joint Venture, ProLogis
Limited Partnership-I, ProLogis Limited Partnership-II, ProLogis Limited
Partnership-III, and ProLogis Limited Partnership-IV). At June 30, 1998, a total
of 5,069,258 limited partnership units were held by minority interest limited
partners in the various real estate partnerships. Limited partners are entitled
to exchange each partnership unit for one Common Share and are entitled to
receive preferential cumulative quarterly distributions per unit equal to the
quarterly distribution in respect of Common Shares. For the six months ended
June 30, 1998, distributions of $3.1 million were made to the minority interest
limited partners. For financial reporting purposes, the assets, liabilities,
results of operations and cash flows of these partnerships are included in
ProLogis' consolidated financial statements and the third party investors'
interests in the partnerships are reflected as minority interest.

     During the six months ended June 30, 1998, ProLogis increased its ownership
in one partnership, ProLogis Limited Partnership-IV, from 96.36% to 97.57% by
contributing additional funds to the partnership in conjunction with tax
deferred exchanges of real estate. The additional contribution aggregated $2.4
million.

6.  Distributions and Dividends:

    Common Share Distributions

     On March 5, 1998, the Board increased ProLogis' annual distribution to
$1.24 per Common Share from $1.14 per Common Share. ProLogis paid quarterly
distributions of $0.285 per Common Share on February 24, 1998 and $0.3183 per
Common Share on May 26, 1998. On July 24, 1998, the Board declared a quarterly
distribution of $0.3183 per Common Share payable on August 25, 1998 to
shareholders of record on August 10, 1998.

    Preferred Share Dividends

     During 1998, ProLogis paid quarterly dividends of:

  .  $0.5875 per cumulative redeemable Series A preferred share on March 31,
     1998 and June 30, 1998;
  .  $0.4375 per cumulative convertible Series B preferred share ("Series B
     Preferred Share") on March 31, 1998 and June 30, 1998;
  .  $1.0675 per cumulative redeemable Series C preferred share on March 31,
     1998 and June 30, 1998; and,
  .  $0.43 per cumulative redeemable Series D preferred share on a prorated
     basis for the period from April 13, 1998 (date of issuance) to June 30,
     1998 on June 30, 1998.


7.  Shareholders' Equity:

    Authorized Shares

     At the annual meeting on June 30, 1998, the shareholders of ProLogis
approved an amendment to the Declaration of Trust to increase the number of
authorized shares of beneficial interest to 230,000,000 shares from 180,000,000
shares.

    Completed Equity Offerings

     ProLogis sold 4,000,000 Common Shares on March 18, 1998 and 1,493,878
Common Shares on April 29, 1998. The sales were made through underwritten public
offerings and generated proceeds, net of underwriting discounts and offering
costs, of $95.7 million and $34.7 million, respectively.

     On April 13, 1998, ProLogis issued 10,000,000 shares of Series D Cumulative
Redeemable Preferred Stock, par value $0.01 per share with a stated liquidation
preference of $25.00 per share (the "Series D Preferred Shares"). Holders of the
Series D Preferred Shares are entitled to receive cumulative preferential cash
distributions at a rate of 7.92% of the liquidation preference per annum (equal
to $1.98 per share). Such distributions are payable quarterly in arrears, when,
and if, declared by the ProLogis Board, out of funds legally available for
payment of distributions. Subject to certain conditions, the holders of Series D
Preferred Shares have limited voting rights. The Series D Preferred Shares are
redeemable on or after April 13, 2003 by ProLogis for cash at the stated
redemption price, plus accrued and unpaid distributions. The redemption price

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
                                        

(other than the portion thereof consisting of accrued and unpaid distributions)
is payable solely out of the sales proceeds of other capital shares of ProLogis,
which may include shares of other series of preferred shares. The Series D
Preferred Shares rank on parity with the other series of preferred shares of
ProLogis with respect to payment of distributions and amounts upon liquidation.
Net proceeds from the offering were $241.7 million, net of underwriting discount
and offering costs.

     Shelf Registration

     On May 15, 1998, ProLogis filed an $800 million shelf registration
statement with the Securities and Exchange Commission, which was declared
effective on May 29, 1998. This shelf registration supplemented an existing
shelf registration with a balance of $183 million. As a result of this filing,
ProLogis can issue securities in the form of debt securities, preferred shares,
Common Shares, rights to purchase Common Shares and preferred share purchase
rights on an as-needed basis, subject to ProLogis' ability to effect offerings
on satisfactory terms. After giving effect to the July 1998 issuance of the 2006
Notes discussed in Note 4, ProLogis has $733 million of shelf-registered
securities available for issuance.

    Share in subsequent periods.

9.  Derivative Financial Instruments:

     ProLogis has only limited involvement with derivative financial instruments
and does not use them for trading purposes.  ProLogis uses derivatives to manage
well-defined risk associated with interest and foreign currency rate
fluctuations on existing obligations or anticipated transactions.

     The primary risks associated with derivative instruments are market risk
(price risk) and credit risk.  Price risk is defined as the potential for loss
in the value of the derivative due to adverse changes in market prices (interest
or foreign currency rates).  Through hedging, ProLogis can effectively manage
the risk of increases in interest rates and fluctuations in foreign currency
exchange rates.

     Credit risk is the risk that the counterparty to a derivative contract
fails to perform or meet its financial obligation under the contract.  ProLogis
does not obtain collateral to support financial instruments subject to credit
risk but monitors the credit standing of counterparties.  ProLogis does not
anticipate non-performance by any of the counterparties to its derivative
contracts.  Should a counterparty fail to perform, however, ProLogis would incur
a financial loss to the extent of the positive fair market value of the
derivative instruments, if any.

     In October 1997, in anticipation of debt offerings in 1998, ProLogis
entered into two interest rate protection agreements which have been renewed
past the original termination dates.  The agreements currently in effect are:

  .  a forward treasury lock agreement with a notional amount of $75 million
     that terminates on August 31, 1998 and effectively locks in the 30-year
     treasury rate can be used to price a future long-term debt issue at 6.36%;
     and,

  .  a swap agreement with a notional amount of $75 million that terminates on
     August 28, 1998 and carries a fixed rate of 6.754%.

     At June 30, 1998, based on quoted market prices, the fair value of the
forward treasury lock agreement was a loss of approximately $7.6 million and the
fair value of the swap agreement was a loss of approximately $6.9 million.

To the Board of Trustees and Shareholders of
  ProLogis Trust:

     We have reviewed the accompanying consolidated balance sheet of ProLogis
Trust and subsidiaries as of June 30, 1998, and the related consolidated
statements of income and comprehensive income for the three and six months ended
June 30, 1998 and 1997, and the consolidated statements of cash flows for the
six months ended June 30, 1998 and 1997.  These financial statements are the
responsibility of the Trust's management.

     We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical procedures to
financial data and making inquiries of persons responsible for financial and
accounting matters.  It is substantially less in scope than an audit conducted
in accordance with generally accepted auditing standards, the objective of which
is the expression of an opinion regarding the financial statements taken as a
whole.  Accordingly, we do not express such an opinion.

     Based on our review, we are not aware of any material modifications that
should be made to the financial statements referred to above for them to be in
conformity with generally accepted accounting principles.

     We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of ProLogis Trust and subsidiaries as
of December 31, 1997, and in our report dated March 13, 1998, we expressed an
unqualified opinion on that statement.  In our opinion, the information set
forth in the accompanying consolidated balance sheet as of December 31, 1997, is
fairly stated in all material respects, in relation to the consolidated balance
sheet from which it has been derived.

ITEM 2:  Management's Discussion and Analysis of Financial Condition and Results
of Operations

The following information should be read in conjunction with ProLogis' 1997
Annual Report on Form 10-K as well as the unaudited consolidated financial
statements and notes included in Item 1 of this report.  See ProLogis' 1997
Annual Report on Form 10-K for a discussion of various risk factors associated
with forward-looking statements made in these documents.


Overview

     ProLogis' operating results depend primarily on the operating results of
its distribution properties, which are substantially influenced by (i) the
demand for and supply of distribution properties in ProLogis' target market
cities; (ii) the pace and economic returns at which ProLogis can acquire and
develop additional distribution properties; (iii) the extent to which ProLogis
can sustain improved market performance as measured by lease rates and occupancy
levels; and, (iv) the demand for the corporate distribution facilities services
that are provided by ProLogis Development Services. In addition, the operating
performance of ProLogis' two unconsolidated subsidiaries that are engaged in the
refrigerated distribution business effect ProLogis' operating results.

     ProLogis' target market cities and submarkets have benefited substantially
in recent periods from demographic trends (including population and job growth)
which influence the demand for distribution properties. ProLogis believes its
ability to compete is significantly enhanced relative to other companies due
to its depth of management and ability to serve customers through the ProLogis
International Operating System(TM), which includes acquisition, development,
property management personnel, and presence in local markets.

     At June 30, 1998, ProLogis' real estate investments included 97.3 million
square feet of operating properties with a total expected investment of $3.0
billion. During the six months ended June 30, 1998, ProLogis acquired 3.0
million square feet of operating properties at a total expected investment of
$87.2 million, while disposing of properties from its operating portfolio
aggregating 948,000 square feet.  For the six months ended June 30, 1998,
ProLogis recognized $7.0 million of other real estate income related to the
activities of ProLogis Development Services, primarily from the disposition of
undepreciated property.

     ProLogis had 11.5 million square feet of properties under development at
June 30, 1998 with a total expected investment at completion of $429.7 million.
Development starts during the six months ended June 30, 1998 aggregated 7.8
million square feet at a total expected investment of $283.3 million.
Development completions during this period aggregated 4.4 million square feet at
a total expected investment of $169.3 million. At June 30, 1998, ProLogis had
1,621 acres of land in inventory for the future development of approximately
28.5 million square feet of distribution facilities.

     During the first six months of 1997, ProLogis began expanding its
distribution facilities operations into Europe and Mexico. This expansion was
necessary to meet the needs of its targeted national and international customers
as they expand and reconfigure their distribution facility requirements
globally. With over 20 target market cities identified in Europe and five target
market cities identified in Mexico, ProLogis believes significant growth
opportunities exist internationally to enable ProLogis to meet its objective of
achieving long-term sustainable growth in cash flow. At June 30, 1998, ProLogis
owned 1,288,000 square feet of operating properties with a total expected
investment of $55.2 million in Europe and 887,000 square feet of operating
properties with a total expected investment of $32.1 million in Mexico.
Additionally, at June 30, 1998, ProLogis had 492,000 square feet with a total
expected investment of approximately $28.3 million under development in Europe
and 1,122,000 square feet with a total expected investment of $43.0 million
under development in Mexico.

     At June 30,1998, ProLogis' had approximately 274.5 million cubic feet of 
refrigerated distribution facilities in operation (178.5 million located in 
Europe) through its investment in two unconsolidated subsidiaries.

     No assurance can be given that the current cost of funds available to
ProLogis will be available in the future.  Additionally, no assurance can be
given that the expected trends in leasing rates and economic returns on acquired
and developed properties will be realized.  There are risks associated with
ProLogis' development and acquisition activities which include future factors
such as development and acquisition opportunities explored by ProLogis may be
abandoned; construction costs of a project may exceed original estimates due to
increased materials, labor or other expenses; and construction and lease-up may
not be completed on schedule, resulting in increased debt service expense and
construction costs.  Acquisition activities entail risks that investments will
fail to perform in accordance with expectations and that analysis with respect
to the cost of improvement to bring an acquired project up to standards will
prove inaccurate, as well as general investment risks associated with any new
real estate investment.  Although ProLogis undertakes a thorough evaluation of
the physical condition of each proposed investment before it is acquired,
certain defects or necessary repairs may not be detected until after it is
acquired, which could increase ProLogis' total acquisition cost.  Risks include
the occurrence of any of the events described above that could adversely affect
ProLogis' ability to achieve its projected returns on acquisitions and projects
under development and could hinder ProLogis' ability to make expected
distributions to equity holders.


Results of Operations

     Six Months Ended June 30, 1998 and 1997

     Net earnings attributable to Common Shares increased by $11.6 million to
$51.4 million for the first six months of 1998 from $39.8 million for the same
period in 1997.  The increase in net earnings resulted from:

  .  an increase in net operating income from property operations (after
     deductions for depreciation), primarily the result of the increased number
     of distribution properties in operation in 1998 as compared to 1997;
  .  an increase in other real estate income, primarily gains on dispositions of
     undepreciated properties and fees generated by ProLogis Development
     Services;
  .  additional investments in refrigerated distribution businesses since June
     30, 1997;
  .  a net foreign exchange gain recognized during 1998; and,
  .  a reduction in expenses resulting from the internalization of management
     transaction that occurred in September 1997.

                                       17
<PAGE>
 
     Interest expense, preferred share dividends and weighted-average Common
Shares outstanding all increased for the first six months of 1998 as compared to
the first six months of 1997, as additional debt and equity were used by
ProLogis to finance its increased acquisition and development activities.

     Net earnings is expected to increase in subsequent periods due to the
acquisition and development of additional operating properties. In addition,
ProLogis anticipates that rental rates and occupancy levels will continue to
increase in subsequent periods and that the activities of ProLogis Development
Services will continue to generate other real estate income. ProLogis'
investments in the refrigerated distribution businesses are also expected to
have a positive effect on its results of operations in the future.

     Property Operations

     At June 30, 1998 ProLogis had 1,053 operating properties totaling 97.3
million of rentable square feet, an increase of 12.0 million square feet over
June 30, 1997. This increase in operating properties resulted in an increase in
property-level net operating income of $25.9 million as follows (in thousands):

</TABLE>

     Rental income increased by $26.4 million for the first six months of 1998
as compared to the same period in 1997. This increase is comprised from the
following components:

  .  properties acquired or developed during the first six months of 1998
     contributed $1.2 million and $2.7 million of additional rental revenues,
     respectively;

  .  properties acquired or developed during 1997 contributed $8.9 million and
     $11.1 million of additional rental revenues, respectively;

  .  properties owned and operated at January 1, 1997 contributed $8.6 million
     of additional rental revenues; and,

  .  properties that were in operation during the first six months of 1997 but
     have subsequently been disposed of reduced rental revenues for the first
     six months of 1998 by $6.1 million. Of the properties acquired or developed
     in 1997 and 1998, three have been disposed of as of June 30, 1998.

     Rental expenses, including property management fees paid to affiliate in
1997, net of recoveries from tenants, increased $475,000 for the first six
months of 1998 over the same period in 1997. Gross expenses, before the
deduction of amounts recovered from tenants, were approximately 25% of rental
income for both of the six-month periods ended June 30, 1998 and 1997.

                                      18

<PAGE>
 
     ProLogis acquired its property management company from Security Capital,
its largest shareholder, on September 9, 1997.  The property management company
managed approximately 96% of ProLogis' operating portfolio prior to the
acquisition.  As a result, ProLogis no longer pays a property management fee on
the properties managed by this company.  However, ProLogis has recognized the
actual personnel and other operating costs associated with the property
management function in rental expenses in 1998.

     ProLogis frequently acquires properties that are underleased and develops
properties which are not fully leased at the start of construction, which
reduces ProLogis' overall occupancy rate below its stabilized level but provides
opportunities to increase revenues. The term "stabilized" means that capital
improvements, repositioning, new management and new marketing programs (or
development and marketing, in the case of newly developed properties) have been
completed and in effect for a sufficient period of time (but in no case longer
than 12 months for properties acquired by ProLogis and 12 months after shell
completion for properties developed by ProLogis) to achieve stabilized occupancy
(typically 93%). ProLogis has been successful in increasing occupancies on
acquired and developed properties during their initial months of operation
resulting in an occupancy rate of 94.7% and a leased rate of 96.2% for
stabilized properties owned at June 30, 1998. The average increase in rental
rates for new and renewed leases on previously leased space (17.4 million square
feet) during the first six months of 1998 was 14.5%. As leases are renewed or
new leases are acquired, ProLogis expects most lease rates on renewals or new
leases to increase in the remainder of 1998.

     Other Real Estate Income

     Other real estate income consists primarily of gains on the disposition of
undepreciated properties and fees and other income received from corporate
distribution facilities customers. Other real estate income is generated to a
large extent by ProLogis Development Services. ProLogis Development Services
develops corporate distribution facilities to meet specific customer
requirements or contracts on a fee basis to develop distribution facilities for
customers. Through its preferred stock ownership of ProLogis Development
Services, ProLogis realizes substantially all economic benefits of these
activities. ProLogis advances mortgage loans to ProLogis Development Services to
fund its acquisition, development and construction activities. ProLogis accounts
for these loans as real estate investments, effectively consolidating the
activities of ProLogis Development Services. Due to the timing of the completion
of these development projects and the related dispositions, other real estate
income recognized by ProLogis will vary on a quarterly basis.

     Income (Loss) from Unconsolidated Subsidiaries

     Income (loss) from unconsolidated subsidiaries relates to ProLogis'
investments in 100% of the preferred stock of two companies, whose primary
source of income is their respective investments in refrigerated distribution
businesses. These investments, discussed in Note 3 to the Consolidated Financial
Statements in Item 1, generated income as follows (in thousands):

(a)  ProLogis Logistics was acquired on April 24, 1997.

(b)  Frigoscandia S.A. was acquired on January 16, 1998.

(c)  Frigoscandia S.A.'s loss for the six months ended June 30, 1998 includes
     $2.5 million of unrealized losses on the remeasurement of assets and
     liabilities based on the foreign exchange rates as of June 30, 1998.

     Foreign Exchange Gain

     The foreign exchange gain for the six months ended June 30, 1998 consists
of a gain of $2,054,000 associated with forward exchange contracts and a gain of
$9,000 related to remeasurement adjustments.

     On December 22, 1997, ProLogis entered into two separate contracts to (i)
exchange $373.8 million for 2.9 billion Swedish krona, and (ii) exchange 310.0
million German marks for $175.0 million in anticipation of the January 1998
acquisition and planned European currency denominated financing of Frigoscandia
AB by Frigoscandia S.A., ProLogis' unconsolidated subsidiary. The contracts were
marked to market at December 31, 1997 and ProLogis recognized a net loss of $6.0
million in 1997. Both contracts were settled during the first quarter of 1998
and ProLogis recognized a net gain of $2.1 million. These foreign exchange
hedges were one-time, non-recurring contracts that fixed the exchange rate
between the U.S. dollar and the Swedish krona and German mark. ProLogis executed
these hedges after the purchase agreement to acquire Frigoscandia AB, which
required payment in Swedish krona was executed. The contracts were executed
exclusively for the acquisition and financing of Frigoscandia AB and were not
entered into to hedge on-going income in foreign currencies.

     The remeasurement of intercompany assets and liabilities on the financial
statements of ProLogis' consolidated foreign subsidiaries into their functional
currency, as required by GAAP, resulted in a foreign exchange gain of $9,000 for
the six months ended June 30, 1998. The gain was associated with the
remeasurement of intercompany loans between the wholly-owned foreign subsidiary
of ProLogis and its associated foreign subsidiaries.

     Interest Income

     Interest income for the first six months of 1998 increased $208,000 from
the same period in 1997. The increase in interest income was primarily a result
of higher average cash balances in the first six months of 1998 compared to the
same period in 1997.

     Depreciation and Amortization

     The increase in depreciation and amortization expense of $9.7 million for
the six months ended June 30, 1998 as compared to the same period in 1997
results primarily from the increase in operating properties in 1998. See 
"--Property Operations".

     Interest Expense

     Interest expense is summarized as follows (in thousands):

</TABLE>

     Interest expense on line of credit borrowings increased $5.8 million for
the first six months of 1998 over the same period in 1997 due primarily to a
higher average outstanding balance ($219.1 million in 1998 compared to $42.2
million in 1997) partially offset by a lower weighted-average daily interest
rate (6.60% in 1998 compared to 6.82% in 1997). Of the interest expense incurred
in 1998, $2.7 million related to the $200 million bridge loan associated with
the Frigoscandia AB acquisition in the first quarter of 1998, which was repaid
on March 31, 1998. See "--Liquidity and Capital Resources--Investing and
Financing Activities".

     Long-term debt interest increased by $4.3 million for the six months ended
June 30, 1998 as compared to the six months ended June 30, 1997 due primarily to
the interest incurred in 1998 on a $100 million long-term debt issuance in July
1997.

     Interest expense recognized on borrowings is offset by interest capitalized
with respect to ProLogis' development activities. Capitalized interest increased
by $423,000 in the first six months of 1998 over the first six months of 1997.
Capitalized interest levels are reflective of ProLogis' cost of funds and the
level of development activity.

General and Administrative Expense, Administrative Expense Services Fee and REIT
  Management Fee

     ProLogis acquired its REIT management company from Security Capital on
September 9, 1997 and terminated the REIT Management Agreement. The REIT
management fee previously paid to the REIT management company was replaced with
the actual personnel and other operating costs associated with the REIT
management function. These costs are recorded as general and administrative
expenses in 1998. Direct and incremental costs related to successful development
and leasing activities have been capitalized in accordance with GAAP.

     Upon consummation of this acquisition, ProLogis entered into an
administrative services agreement ("ASA") with Security Capital for services
which include, but are not limited to, payroll and human resources, cash
management, accounts payable, MIS support and other computer services, research,
investor relations and insurance, legal and tax administration. These services
are provided in exchange for a fee equal to Security Capital's direct cost of
providing the service plus an overhead factor of 20%, subject to a maximum of
approximately $2.0 million for the period from September 9, 1997 to December 31,
1997 and $5.1 million for 1998.

     ASA fees for the six months ended June 30, 1998 aggregated $1.8 million,
including $445,000 that has been recognized as rental expenses. Of the total ASA
fees, $296,000 have been capitalized. The ASA, which expires on December 31,
1998, provides for automatic renewals of consecutive one-year terms, subject to
approval by a majority of the independent members of the Board.

     Other Expense

     Other expenses, which increased by $56,000 for the six months ended June
30, 1998 over the six months ended June 30, 1997, consist of land holding costs
and the write-off of previously capitalized pursuit costs. Land holding costs
were $1,147,000 for the first six months of 1998 compared to $1,016,000 for the
same period in 1997 and pursuit cost write-offs were $370,000 for the first six
months of 1998 compared to $445,000 for the same period in 1997.

     Preferred Share Dividends

     The increase in preferred share dividends of $4.2 million for the six
months ended June 30, 1998 over the same period in 1997 is primarily
attributable to the issuance of Series D Preferred Shares in April 1998. 
See "--Liquidity and Capital Resources--Investing and Financing Activities".

     Three Months Ended June 30, 1998 and 1997

     Net earnings attributable to Common Shares and its components for the three
months ended June 30, 1998 compared to three months ended June 30, 1997 reflect
changes similar to those discussed in the preceding paragraphs for comparison of
the six months ended on the same dates. The changes for the three-month periods
are substantially attributable to the same reasons discussed in the preceding
paragraphs.

Liquidity and Capital Resources

     Overview

     ProLogis considers its liquidity and ability to generate cash from
operations and financing to be adequate and expects it to continue to be
adequate to meet its development, acquisition, operating and debt service needs
as well as its shareholder distribution requirements.

     ProLogis expects to finance future activities with cash on hand,
redeployment of proceeds from the disposition of selected properties, borrowings
on its line of credit, issuance of limited partnership units, the assumption of
existing mortgage debt, when applicable, long-term debt issuances and sales of
Common Shares and preferred shares. The line of credit provides ProLogis with
the ability to efficiently respond to market opportunities while minimizing the
amount of cash invested in short-term investments at lower yields. At June 30,
1998 ProLogis had $158.4 million available for borrowing under the line of
credit ($328.9 million available at August 10, 1998). Another source of future
liquidity and financial flexibility is ProLogis' shelf-registered securities
($733.0 million available at August 10, 1998) which can be issued in the form of
debt securities, preferred shares, Common Shares, rights to purchase Common
Shares and preferred share purchase rights on an as-needed basis, subject to
ProLogis' ability to effect an offering on satisfactory terms.

     Operating Activities

     Cash provided by operating activities increased by $16.1 million during the
first six months of 1998 as compared to the first six months of 1997 ($100.4
million in 1998 and $84.3 million in 1997). This increase is primarily the
result of the increased number of operating properties in 1998 over 1997. See
"--Results of Operations--Property Operations".

     Investing and Financing Activities

     ProLogis funds its current investment needs primarily with line of credit
borrowings, which are subsequently repaid with proceeds from sales of debt and
equity securities. ProLogis' investment activities used approximately $531.0
million and $267.4 million of cash during the first six months of 1998 and 1997,
respectively. ProLogis' financing activities provided net cash flow of $468.9
million and $187.9 million during the first six months of 1998 and 1997,
respectively. Cash distributions paid on Common Shares were $72.6 million and
$51.3 million for the six months ended June 30, 1998 and 1997, respectively,
which have been substantially funded by cash generated from operating
activities.

     Investments in real estate, net of proceeds from dispositions, used cash of
$240.3 million during the first six months of 1998 and $192.3 million during the
first six months of 1997. ProLogis' cash investment in ProLogis Logistics and
related subsidiaries was $76.7 million during the first six months of 1998 and
$75.2 million during the first six months of 1997. During 1998, ProLogis' net
cash investment in Frigoscandia S.A. and related subsidiaries aggregated $214.0
million.

     ProLogis' primary financing activities in the first six months of 1998
were: (i) the sale of Series D Preferred Shares generating net proceeds of
$241.7 million; (ii) the sale of Common Shares (including sale of Common Shares
under the share purchase plan) generating net proceeds of $130.6 million; (iii)
net borrowings on ProLogis' lines of credit of $216.6 million; and, (iv)
proceeds from a short-term bridge loan from NationsBank of $200 million (used
primarily to finance the acquisition of Frigoscandia AB), which was repaid on
March 31, 1998 after Frigoscandia Holding AB obtained third-party financing.

     ProLogis' primary financing activities during the first six months of 1997
were: (i) the issuance of long-term debt generating net proceeds of $99.1
million; (ii) the sale of Common Shares (including the sale of Common Shares
under the share purchase plan) generating net proceeds of $80.7 million; and,
(iii) net borrowings on ProLogis' lines of credit of $91.5 million.

     On July 20, 1998, ProLogis completed a $250 million offering of debt
securities due July 15, 2006 with a coupon rate of 7.05%. The securities were
issued at a discount resulting in a yield to maturity of 7.08%. Net proceeds
from the offering were approximately $247.6 million, net of underwriters'
commissions and other costs. The proceeds were used to repay borrowings on
ProLogis' line of credit.

     Line of Credit

     On August 11, 1998, ProLogis entered into an amended and restated credit
agreement with NationsBank that provides for a $350 million unsecured revolving
line of credit. The new agreement, which replaces the credit agreement in effect
at June 30, 1998, provides for interest at ProLogis' option, at either (a) the
greater of the federal funds rate plus 0.5% and the prime rate, or (b) LIBOR
plus 0.75% based upon ProLogis' current senior debt ratings. In addition,
ProLogis pays certain annual fees. Under a competitive bid option contained in
the new line of credit agreement, ProLogis may be able to borrow at a lower
interest rate spread over LIBOR, depending on market conditions. This option is
available on up to $100 million of borrowings. The line of credit matures on May
1, 2000 and may be extended annually for an additional year with the approval of
NationsBank and the other participating lenders. All borrowings on the line of
credit are subject to certain covenants similar to those contained in the
previous line of credit agreement.

     In addition, ProLogis has a $25 million short-term, unsecured discretionary
line of credit with NationsBank that provides for additional flexibility through
same day borrowings and more efficient cash management.

     Derivative Financial Instruments

     ProLogis utilizes derivative instruments in anticipation of future
financing transactions in order to manage well defined interest rate risk.
Through hedging, ProLogis can effectively manage the risk of increases in
interest rates on future debt issuances. In October 1997, in anticipation of
debt offerings in 1998, ProLogis entered into two interest rate protection
agreements which have been renewed past the original termination dates. The
agreements currently in effect are:

  .  a forward treasury lock agreement with a notional amount of $75 million
     that terminates on August 31, 1998 and effectively locks in the 30-year
     treasury rate that can be used to price a future long-term debt issue at
     6.36%; and,

  .  a swap agreement with a notional amount of $75 million that terminates on
     August 28, 1998 and carries a fixed rate of 6.754%.

     At June 30, 1998, based on quoted market prices, the fair value of the 
forward treasury lock agreement was a loss of approximately $7.6 million and the
fair value of the swap agreement was a loss of approximately $6.9 million.

     ProLogis intends to also utilize derivative instruments in order to manage
currency risk exposure associated with foreign currency denominated purchase
contracts and income in excess of interest expense. ProLogis had no open foreign
currency contracts as of June 30, 1998. In future periods, ProLogis will
consider using selective currency hedges through foreign exchange forwards or
options in order to minimize on-going currency gains and losses.

     Commitments

     At June 30, 1998, ProLogis had letters of intent or contingent contracts,
subject to ProLogis' final due diligence, for the acquisition of 6.5 million
square feet in various target markets with an acquisition cost of $289.1
million. Through July 31, 1998, ProLogis had completed the acquisition of 
811,000 square feet at an acquisition cost of $47.5 million of properties 
subject to these contingent contracts. In addition, ProLogis had a letter of 
intent to acquire an industrial distribution development company located in the 
United Kingdom for approximately $160 million. This acquisition would be made 
through the formation of a subsidiary, of which ProLogis would own 100% of the 
preferred stock and recognize substantially all economic benefits of its 
activities. The foregoing transactions are subject to a number of conditions,
and ProLogis cannot predict with certainty that any of them will be consummated.
In addition, at June 30, 1998, ProLogis had $429.7 million of budgeted
development cost for developments in process, of which $248.2 million was
unfunded.

     ProLogis' current distribution policy is to pay quarterly distributions to
shareholders based upon what it considers to be a reasonable percentage of cash
flow and at the level that will allow ProLogis to continue to qualify as a REIT
for tax purposes. Because depreciation is a non-cash expense, cash flow
typically will be greater than earnings from operations and net earnings.
Therefore, quarterly distributions are expected to be consistently higher than
quarterly earnings.

     Pursuant to the terms of the Series A Preferred Shares, the Series B
Preferred Shares, the Series C Preferred Shares and the Series D Preferred
Shares (the "Preferred Shares"), ProLogis is restricted from declaring or paying
any distribution with respect to the Common Shares unless all cumulative
distributions with respect to the Preferred Shares have been paid and sufficient
funds have been set aside for distributions that have been declared for the then
current distribution period with respect to the Preferred Shares.

     Funds from Operations

     Funds from operations attributable to Common Shares increased $36.2 million
to $111.1 million for the first six months of 1998 from $74.9 million for the
same period in 1997.

     Funds from operations represent ProLogis' net earnings (computed in
accordance with GAAP) before minority interest, before gains or losses on
disposition of depreciated real estate, before gains or losses on the
remeasurement of assets and liabilities on the financial statements of ProLogis'
foreign subsidiary and before deferred tax benefits or deferred tax expenses of
ProLogis' taxable subsidiaries, plus real estate depreciation and amortization
(exclusive of amortization of loan costs). ProLogis believes that funds from
operations is helpful to a reader as a measure of the performance of an equity
REIT because, along with cash flow from operating activities, financing
activities and investing activities, it provides a reader with an indication of
the ability of ProLogis to incur and service debt, to make capital expenditures
and to fund other cash needs. The funds from operations measure presented by
ProLogis, while consistent with the National Association of Real Estate
Investment Trusts' definition, will not be comparable to similarly titled
measure of other REITs which do not compute funds from operations in a manner
consistent with ProLogis. Funds from operations is not intended to represent
cash made available to shareholders. Funds from operations should not be
considered as an alternative to net earnings or any other GAAP measurement of
performance as an indicator of ProLogis' operating performance, or as an
alternative to cash flows from operating, investing or financing activities as a
measure of liquidity. Funds from operations were as follows (in thousands):

                                PROLOGIS TRUST

          The undersigned, being an officer duly authorized by a majority of the
Trustees of ProLogis Trust, a Maryland real estate investment trust (the
"Trust"), does hereby certify pursuant to the provisions of Article 7, Section 1
of the Trust's Amended and Restated Declaration of Trust, dated as of December
15, 1993, as amended and supplemented (the "Declaration of Trust"), and Section
8-501 of the Corporations and Associations Article of the Annotated Code of
Maryland, that the Board of Trustees of the Trust has adopted a resolution
declaring this amendment to the Declaration of Trust as hereinafter set forth to
be advisable and that the shareholders of the Trust have approved such amendment
by the affirmative vote of at least a majority of all the votes entitled to be
cast on the matter.

          Therefore, the Trust's Declaration of Trust is hereby amended as
follows:

          1. The first two paragraphs of Article 1, Section 1 are hereby amended
to read in their entirety as follows:

               "Section 1 Name. The Trust created by this Declaration of Trust
          is herein referred to as the "Trust" and shall be known by the name
          "ProLogis Trust." So far as may be practicable, legal and convenient,
          the affairs of the Trust shall be conducted and transacted under that
          name, which name shall not refer to the Trustees individually or
          personally or to the beneficiaries or Shareholders of the Trust, or to
          any officers, employees or agents of the Trust.

               Under circumstances in which the Trustees determine that the use
          of the name "ProLogis Trust" is not practicable, legal or convenient,
          they may as appropriate use their names with suitable reference to
          their trustee status, or some other suitable designation, or they may
          adopt another name under which the Trust may hold property or operate
          in any jurisdiction which name shall not, to the knowledge of the
          Trustees, refer to beneficiaries or Shareholders of the Trust. Legal
          title to all the properties subject from time to time to this
          Declaration of Trust shall be transferred to, vested, and held by the
          Trust in its own name or by the Trustees as joint tenants with right
          of survivorship as Trustees of this Trust, except that the Trustees
          shall have the power to cause legal title to any property of this
          Trust to be held by and/or in the name of one or more of the Trustees,
          or any other person as nominee, on such terms, in such manner, and
          with such powers as the Trustees may determine, provided that the
          interest of the Trust therein is appropriately protected."
<PAGE>
 
          2. The Trust's Declaration of Trust is hereby amended to change the
words "Security Capital Industrial Trust" to "ProLogis Trust" each time they
appear therein.

          3. Article 2, Section 1 is amended by deleting the number
"180,000,000" and inserting the number "230,000,000" in its place.

          Immediately before the adoption of this Amendment, the total number of
shares of all classes which the Trust had authority to issue was 180,000,000
consisting of 150,950,000 common Shares of Beneficial Interest, $0.01 par value
per share ("Common Shares"), 5,400,000 Series A Cumulative Redeemable Preferred
Shares of Beneficial Interest, par value $0.01 per share (the "Series A
Preferred Shares"), 8,050,000 Series B Cumulative Convertible Redeemable
Preferred Shares of Beneficial Interest, par value $0.01 per share (the "Series
B Preferred Shares"), 2,300,000 Series C Cumulative Redeemable Preferred Shares
of Beneficial Interest, par value $0.01 per share (the "Series C Preferred
Shares"), 11,500,000 Series D Cumulative Redeemable Preferred Shares of
Beneficial Interest, par value $0.01 per share (the "Series D Preferred
Shares"), and 1,800,000 Series A Junior Participating Preferred Shares, par
value $0.01 per share (the "Junior Participating Preferred Shares"),
representing an aggregate par value of $1,800,000. Immediately after the
adoption of this Amendment, the total number of shares of all classes which the
Trust has authority to issue is 230,000,000 consisting of 200,450,000 Common
Shares, 5,400,000 Series A Preferred Shares, 8,050,000 Series B Preferred
Shares, 2,300,000 Series C Preferred Shares, 11,500,000 Series D Preferred
Shares and 2,300,000 Junior Participating Preferred Shares, representing an
aggregate par value of $2,300,000.

          The undersigned officer acknowledges these Articles of Amendment to be
the act of the Trust and, as to all other matters or facts required to be
verified under oath, that, to the best of his knowledge, information and belief,
these matters and facts are true in all material respects, and that this
statement is made under the penalties for perjury.

                                PROLOGIS TRUST

          The undersigned, being an officer duly auhtorized by a majority of the
Trustees of ProLogis Trust, a Maryland real estate investment trust (the
"Trust"), does hereby certify pursuant to the provisions of Article 2, Section 1
of the Trust's Amended and Restated Declaration of Trust, dated as of December
15, 1993, as amended and supplemented (the "Declaration of Trust"), and Section
8-203 of the Corporations and Associations Article of the Annotated Code of
Maryland, that:

          FIRST:  The Board of Trustees has classified 2,300,000 unissued shares
of the Trust as Series A Junior Participating Preferred Shares of Beneficial
Interest (the "Preferred Shares").

          SECOND:  The following is a description of the Preferred Shares,
including the preferences, conversion and other rights, voting powers,
restrictions, limitations as to dividends, qualifications, and terms and
conditions of redemption thereof:

          Section 1.  Designation and Amount.  There shall be a series of
preferred shares of the Trust, $0.01 par value per share, which shall be
designated "Series A Junior Participating Preferred Shares," $0.01 par value per
share (hereinafter called "Series A Preferred Shares"), and the number of shares
constituting that series shall be 2,300,000. Such number of shares may be
increased or decreased by resolution of the Board of Trustees and by the filing
of articles supplementary in accordance with the provisions of Title 8 of the
Corporations and Associations Article of the Code of Maryland stating that such
increase or reduction has been so authorized; provided, however, that no
decrease shall reduce the number of shares of Series A Preferred Shares to a
number less than the number of shares of the series then outstanding plus the
number of shares of Series A Preferred Shares issuable upon exercise of
outstanding rights, options or warrants or upon conversion of outstanding
securities issued by the Trust.

          Section 2.  Dividends and Distributions.

          (A) Subject to the prior and superior rights of the holders of any
shares of any class or series of preferred shares of the Trust ranking prior and
superior to the shares of Series A Preferred Shares with respect to dividends,
the holders of shares of Series A Preferred Shares shall be entitled to receive,
when, as and if declared by the Board of Trustees out of funds legally available
for the purpose, quarterly dividends payable in cash to holders of record on the
last business day of January, April, July and October in each year (each such
date being referred to herein as a "Quarterly Dividend Payment Date"),
(commencing on the first Quarterly Dividend Payment Date after the first
issuance of a share or fraction of a share of Series A
<PAGE>
 
Preferred Shares) in an amount per share (rounded to the nearest cent) equal to
the greater of (a) $1.00 or (b) subject to the provision for adjustment
hereinafter set forth, 100 times the aggregate per share amount of all cash
dividends, and 100 times the aggregate per share amount (payable in kind) of all
non-cash dividends or other distributions other than a dividend payable in
shares of Common Shares (hereinafter defined) or a subdivision of the
outstanding shares of Common Shares (by a reclassification or otherwise),
declared on the Shares of Beneficial Interest, par value $0.01 per share, of the
Trust (the "Common Shares") since the immediately preceding Quarterly Dividend
Payment Date, or, with respect to the first Quarterly Dividend Payment Date,
since the first issuance of any share or fraction of a share of Series A
Preferred Shares. In the event the Trust shall at any time following December
31, 1993 (i) declare any dividend on Common Shares payable in shares of Common
Shares, (ii) subdivide the outstanding Common Shares or (iii) combine the
outstanding Common Shares into a smaller number of shares, then in each such
case the amount to which holders of Series A Preferred Shares were entitled
immediately prior to such event under clause (b) of the preceding sentence shall
be adjusted by multiplying each such amount by a fraction the numerator of which
is the number of Common Shares outstanding immediately after such event and the
denominator of which is the number of Common Shares that were outstanding
immediately prior to such event.

          (B) The Trust shall declare a dividend or distribution on the Series A
Preferred Shares as provided in paragraph (A) above at the time it declares a
dividend or distribution on the Common Shares (other than a dividend payable in
shares of Common Shares).

          (C) No dividend or distribution (other than a dividend or distribution
payable in Common Shares) shall be paid or payable to the holders of Common
Shares unless, prior thereto, all accrued but unpaid dividends to the date of
that dividend or distribution shall have been paid to the holders of Series A
Preferred Shares.

          (D) Dividends shall begin to accrue and be cumulative on outstanding
Series A Preferred Shares from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares of Series A Preferred Shares, unless
the date of issue of such shares is prior to the record date for the first
Quarterly Dividend Payment Date, in which case dividends on such shares shall
begin to accrue and be cumulative from the date of issue of such shares, or
unless the date of issue is a Quarterly Dividend Payment Date or is a date after
the record date for the determination of holders of shares of Series A Preferred
Shares entitled to receive a quarterly dividend and before such Quarterly
Dividend Payment Date, in either of which events such dividends shall begin to
accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but
unpaid dividends shall not bear interest. Dividends paid on the Series A
Preferred Shares in an amount less than the total amount of such dividends at
the time accrued and payable on such shares shall be allocated pro rata on a
share-by-share basis among all such shares at the time outstanding. The Board of
Trustees may fix a record date for the determination of holders of shares of
Series A Preferred Shares entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be no more than 30 days
prior to the date fixed for the payment thereof.

          Section 3.  Voting Rights.  The holders of Series A Preferred Shares
shall have the following voting rights:

          (A) Subject to the provision for adjustment hereinafter set forth,
each one one-hundredth of a share of Series A Preferred Shares shall entitle the
holder thereof to one vote on all matters submitted to a vote of the
shareholders of the Trust. In the event the Trust shall at any time following
December 31, 1993 (i) declare any dividend on Common Shares payable in shares of
Common Shares, (ii) subdivide the outstanding shares of Common Shares or (iii)
combine the outstanding Common Shares into a smaller number of shares, then in
each such case the number of votes per share to which holders of shares of
Series A Preferred Shares were entitled immediately prior to such event shall be
adjusted by multiplying such number by a fraction the numerator of which is the
number of shares of Common Shares outstanding immediately after such event and
the denominator of which is the number of shares of Common Shares that were
outstanding immediately prior to such event.

          (B) Except as otherwise provided herein or required by law, the
holders of Series A Preferred Shares and the holders of Common Shares and any
other capital shares of the Trust having general voting rights shall vote
together as one class on all matters submitted to a vote of shareholders of the
Trust.

          (C)  (i)  Whenever, at any time or times, dividends payable on any
          share or shares of Series A Preferred Shares shall be in arrears in an
          amount equal to at least six full quarterly dividends (whether or not
          declared and whether or not consecutive), the holders of record of the
          outstanding Preferred Shares shall have the exclusive right, voting
          separately as a single class, to elect two trustees of the Trust at a
          special meeting of shareholders of the Trust or at the Trust's next
          annual meeting of shareholders, and at each subsequent annual meeting
          of shareholders, as provided below. At elections for such trustees,
          the holders of shares of Series A Preferred Shares shall be entitled
          to cast one vote for each one one-hundredth of a share of Series A
          Preferred Shares held.

               (ii) Upon the vesting of such right of the holders of the
          Preferred Shares, the maximum authorized number of members of the
          Board of Trustees shall automatically be increased by two and the two
          vacancies so created shall be filled by vote of the holders of the
          outstanding Preferred Shares as hereinafter set forth. A special
          meeting of the shareholders of the Trust then entitled to vote shall
          be called by the Chairman or the President or the Secretary of the
          Trust, if requested in writing by the holders of record of not less
          than 10% of the Preferred Shares then outstanding. At such special
          meeting, or, if no such special meeting shall have been called, then
          at the next annual meeting of shareholders of the Trust, the holders
          of the shares of the Preferred Shares shall elect, voting as above
          provided, two trustees of the Trust to fill the aforesaid vacancies
          created by the automatic increase in the number of members of the
          Board of Trustees. At any and all such meetings for such election, the
          holders of a majority of the outstanding shares of the Preferred
          Shares shall be necessary to constitute a quorum for such election,
          whether present in person or by proxy, and such two trustees shall be

                                       3
<PAGE>
 
          elected by the vote of at least a plurality of shares held by such
          shareholders present or represented at the meeting. Any trustee
          elected by holders of shares of the Preferred Shares pursuant to this
          Section may be removed at any annual or special meeting, by vote of a
          majority of the shareholders voting as a class who elected such
          trustee, with or without cause. In case any vacancy shall occur among
          the trustees elected by the holders of the Preferred Shares pursuant
          to this Section, such vacancy may be filled by the remaining trustee
          so elected, or his successor then in office, and the trustee so
          elected to fill such vacancy shall serve until the next meeting of
          shareholders for the election of trustees. After the holders of the
          Preferred Shares shall have exercised their right to elect trustees in
          any default period and during the continuance of such period, the
          number of trustees shall not be further increased or decreased except
          by vote of the holders of Preferred Shares as herein provided or
          pursuant to the rights of any equity securities ranking senior to or
          pari passu with the Series A Preferred Shares.

               (iii)  The right of the holders of the Preferred Shares, voting
          separately as a class, to elect two members of the Board of Trustees
          of the Trust as aforesaid shall continue until, and only until, such
          time as all arrears in dividends (whether or not declared) on the
          Preferred Shares shall have been paid or declared and set apart for
          payment, at which time such right shall terminate, except as herein or
          by law expressly provided, subject to revesting in the event of each
          and every subsequent default of the character above-mentioned. Upon
          any termination of the right of the holders of the shares of the
          Preferred Shares as a class to vote for trustees as herein provided,
          the term of office of all trustees then in office elected by the
          holders of Preferred Shares pursuant to this Section shall terminate
          immediately. Whenever the term of office of the trustees elected by
          the holders of the Preferred Shares pursuant to this Section shall
          terminate and the special voting powers vested in the holders of the
          Preferred Shares pursuant to this Section shall have expired, the
          maximum number of members of the Board of Trustees of the Trust shall
          be such number as may be provided for in the Bylaws of the Trust
          irrespective of any increase made pursuant to the provisions of this
          Section.

          (D) Except as otherwise provided herein or required by law, holders of
Series A Preferred Shares shall have no special voting rights and their consent
shall not be required (except to the extent they are entitled to vote with
holders of Common Shares as provided herein) for taking any trust action.

          Section 4.  Certain Restrictions.

          (A) Whenever any quarterly dividends or other dividends or
distributions payable on the Series A Preferred Shares as provided in Section 2
are in arrears, then, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series A Preferred Shares
outstanding shall have been paid in full, the Trust shall not:

               (i) declare or pay dividends on, make any other distributions on,
          or redeem or purchase or otherwise acquire for consideration any
          shares ranking junior (either as

                                       4
<PAGE>
 
          to dividends or upon liquidation, dissolution or winding up) to the
          Series A Preferred Shares;

               (ii) declare or pay dividends on or make any other distributions
          on any shares ranking on a parity (either as to dividends or upon
          liquidation, dissolution or winding up) with the Series A Preferred
          Shares, except dividends paid ratably on the Series A Preferred Shares
          and all such parity shares on which dividends are payable or in
          arrears in proportion to the total amounts to which the holders of all
          such shares are then entitled;

               (iii) redeem or purchase or otherwise acquire for consideration
          shares ranking on a parity (either as to dividends or upon
          liquidation, dissolution or winding up) with the Series A Preferred
          Shares, provided that the Trust may at any time redeem, purchase or
          otherwise acquire any such parity shares in exchange for shares of the
          Trust ranking junior (either as to dividends or upon dissolution,
          liquidation or winding up) to the Series A Preferred Shares; or

               (iv) purchase or otherwise acquire for consideration any Series A
          Preferred Shares, except in accordance with a purchase offer made in
          writing or by publication (as determined by the Board of Trustees) to
          all holders of such shares upon such terms as the Board of Trustees,
          after consideration of the respective annual dividend rates and other
          relative rights and preferences of the respective series and classes,
          shall determine in good faith will result in fair and equitable
          treatment among the respective series or classes.

          (B) The Trust shall not permit any subsidiary of the Trust to purchase
or otherwise acquire for consideration any shares of the Trust unless the Trust
could, under paragraph (A) of this Section, purchase or otherwise acquire such
shares at such time and in such manner.

     Section 5.  Reacquired Shares.  Any Series A Preferred Shares purchased or
otherwise acquired by the Trust in any manner whatsoever shall be retired and
cancelled promptly after the acquisition thereof. All such shares shall upon
their cancellation become authorized but unissued shares of Preferred Shares and
may be reissued as part of a new series of Preferred Shares to be created by
resolution or resolutions of the Board of Trustees, subject to the conditions
and restrictions on issuance set forth herein.

     Section 6.  Liquidation, Dissolution or Winding Up.  (A)  Upon any
voluntary liquidation, dissolution or winding up of the Trust, no distribution
shall be made to the holders of shares ranking junior (either as to dividends or
upon liquidation, dissolution or winding up) to the Series A Preferred Shares
unless, prior thereto, the holders of shares of Series A Preferred Shares shall
have received $1.00 per share, plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment (the "Series A Liquidation Preference"). Following the payment of
the full amount of the Series A Liquidation Preference, no additional
distributions shall be made to the holders of shares of

                                       5
<PAGE>
 
Series A Preferred Shares unless, prior thereto, the holders of shares of Common
Shares shall have received an amount per share (the "Common Adjustment") equal
to the quotient obtained by dividing (i) the Series A Liquidation Preference by
(ii) 100 (as appropriately adjusted as set forth in subparagraph C below to
reflect such events as share splits, share dividends and recapitalizations with
respect to the Common Shares) (such number in clause (ii), the "Adjustment
Number"). Following the payment of the full amount of the Series A Liquidation
Preference and the Common Adjustment in respect of all outstanding shares of
Series A Preferred Shares and Common Shares, respectively, holders of Series A
Preferred Shares and holders of shares of Common Shares shall receive their
ratable and proportionate share of the remaining assets to be distributed in the
ratio, on a per share basis, of the Adjustment Number to 1 with respect to such
Preferred Shares and Common Shares, on a per share basis, respectively.

     (B) In the event, however, that there are not sufficient assets available
to permit payment in full of the Series A Liquidation Preference and the
liquidation preferences of all other series of Preferred Shares, if any, which
rank on a parity with the Series A Preferred Shares, then such remaining assets
shall be distributed ratably to the holders of such parity shares in proportion
to their respective liquidation preferences.

     (C) In the event the Trust shall at any time following December 31, 1993
(i) declare any dividend on Common Shares payable in shares of Common Shares,
(ii) subdivide the outstanding shares of Common Shares or (iii) combine the
outstanding Common Shares into a smaller number of shares, then in each such
case the Adjustment Number in effect immediately prior to such event shall be
adjusted by multiplying such Adjustment Number by a fraction the numerator of
which is the number of shares of Common Shares outstanding immediately after
such event and the denominator of which is the number of shares of Common Shares
that were outstanding immediately prior to such event.

     Section 7.  Consolidation, Merger, etc.  In case the Trust shall enter into
any consolidation, merger, combination or other transaction in which the Common
Shares are exchanged for or changed into other shares or securities, cash and/or
any other property, then in any such case, the shares of Series A Preferred
Shares shall at the same time be similarly exchanged or changed in an amount per
share (subject to the provision for adjustment hereinafter set forth) equal to
100 times the aggregate amount of shares, securities, cash and/or any other
property (payable in kind), as the case may be, into which or for which each
Common Share is exchanged or changed. In the event the Trust shall at any time
(i) declare any dividend on Common Shares payable in shares of Common Shares,
(ii) subdivide the outstanding Common Shares or (iii) combine the outstanding
Common Shares into a smaller number of shares, then in each such case the amount
set forth in the preceding sentence with respect to the exchange or change of
shares of Series A Preferred Shares shall be adjusted by multiplying such amount
by a fraction the numerator of which is the number of shares of Common Shares
outstanding immediately after such event and the denominator of which is the
number of shares of Common Shares that were outstanding immediately prior to
such event.

                                       6
<PAGE>
 
     Section 8.  Redemption.  The Series A Preferred Shares shall not be
redeemable by the Trust. The preceding sentence shall not limit the ability of
the Trust to purchase or otherwise deal in such shares to the extent permitted
by law.

     Section 9.  Ranking.  The Series A Preferred Shares shall rank junior to
all other series of the Trust's preferred shares (whether with or without par
value) as to the payment of dividends and the distribution of assets, unless the
terms of any such series shall provide otherwise.

     Section 10.  Amendment.  Neither the Declaration of Trust nor any Articles
Supplementary relating to the Series A Preferred Shares shall be amended in any
manner which would materially alter or change the powers, preferences or special
rights of the Series A Preferred Shares so as to affect the holders of Series A
Preferred Shares adversely without the affirmative vote of the holders of a
majority or more of the outstanding shares of Series A Preferred Shares, voting
separately as a class.

     Section 11.  Fractional Shares.  Series A Preferred Shares may be issued in
fractions of a share which shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends and
participate in distributions and to have the benefit of all other rights of
holders of Series A Preferred Shares.

     The undersigned officer acknowledges these Articles of Amendment to be the
act of the Trust and, as to all other matters or facts required to be verified
under oath, that, to the best of his knowledge, information and belief, these
matters and facts are true in all material respects, and that this statement is
made under the penalties for perjury.

                       SECURITY CAPITAL INDUSTRIAL TRUST

     The undersigned, being a vice president and an assistant secretary of
Security Capital Industrial Trust, a Maryland real estate investment trust (the
"Trust"), do hereby certify pursuant to the provisions of Article 8 of the
Amended and Restated Declaration of Trust (the "Declaration of Trust"), and in

     1.  That the Board of Trustees had adopted a resolution to amend the 
Declaration of Trust as hereinafter set forth and has declared that such 
amendment is advisable.

the affirmative vote of at least a majority of the shares entitled to notice of,

SECTION 2  COMMITMENT.
- ---------  ---------- 

     2.1   REVOLVING FACILITY.  Subject to the provisions in the Loan Documents,
each Lender severally and not jointly agrees to lend to Borrower one or more
Borrowings (except for Competitive Borrowings and Swing Line Loans) hereunder
which Borrower may borrow, repay, and reborrow under this Agreement, subject to
the following conditions:

     (A)   each Borrowing requested by Borrower hereunder must occur on a
Business Day and no later than the Business Day immediately preceding the
Termination Date;

     (B)   each Borrowing requested by Borrower must be in an amount not less
than $1,000,000 or a greater integral multiple of $100,000 or, if less, the
Unused Commitment less the Principal Debt of any Swing Line Loans;

     (C)   the Total Principal Debt may not exceed the Total Commitment; and

     (D)   no Lender's Principal Debt may exceed such Lender's Commitment.

     2.2   BORROWING PROCEDURE.  The following procedures apply to Borrowings
(other than Competitive Borrowings and Swing Line Loans):

                                       16
<PAGE>
 
     (A)   Borrower may request a Borrowing by submitting to Administrative
Agent a Borrowing Request. The Borrowing Request must be received by
Administrative Agent no later than 11:00 a.m. on (i) the third (3rd) Business
Day preceding the Borrowing Date for any Eurodollar Borrowing or (ii) the
Business Day preceding the Borrowing Date for any Base Rate Borrowing.
Administrative Agent shall promptly notify each Lender of its receipt of any
Borrowing Request and its contents. A Borrowing Request is irrevocable and
binding on Borrower.

     (B)   By 11:00 a.m. on the applicable Borrowing Date, each Lender shall
remit its Pro Rata Part of each requested Borrowing by wire transfer to
Administrative Agent pursuant to Administrative Agent's wire transfer
instructions on SCHEDULE 1 (or as otherwise directed by Administrative Agent) in
funds that are available for immediate use by Administrative Agent. Subject to
receipt of such funds, Administrative Agent shall make such funds available to
Borrower in Dallas, Texas at 12:00 noon on such Borrowing Date (unless it has
actual knowledge that any applicable condition precedent has not been satisfied
by Borrower).

     (C)   Absent contrary written notice from a Lender, Administrative Agent
may assume that each Lender has made its Pro Rata Part of the requested
Borrowing available to Administrative Agent on the applicable Borrowing Date,
and Administrative Agent may, in reliance upon such assumption (but is not
required to), make available to Borrower a corresponding amount. If a Lender
fails to make its Pro Rata Part of any requested Borrowing available to
Administrative Agent on the applicable Borrowing Date, Administrative Agent may
recover the applicable amount on demand (i) from such Lender, together with
interest at the Federal Funds Rate for the period commencing on the date the
amount was made available to Borrower by Administrative Agent and ending on (but
excluding) the date Administrative Agent recovers the amount from such Lender,
or (ii) if such Lender fails to pay its amount upon demand, then from Borrower,
together with interest at an annual interest rate equal to the rate applicable
to the requested Borrowing for the period commencing on the Borrowing Date and
ending on (but excluding) the date Administrative Agent recovers the amount from
Borrower. No Lender is responsible for the failure of any other Lender to make
its Pro Rata Part of any Borrowing.

     2.3   TERMINATION.  Without premium or penalty, and upon giving at least
three (3) Business Days prior written and irrevocable notice to Administrative
Agent, Borrower may terminate all or part of the unused portion of the Total
Commitment, provided that Borrower may not partially terminate the unused
portion of the Total Commitment such that the Total Commitment is less than
$200,000,000.  Each partial termination must be in an amount of not less than
$1,000,000 or a greater integral multiple of $1,000,000, and shall be Pro Rata
among all Lenders.  Once terminated, the Total Commitment may not be increased
or reinstated.

     2.4   SWING LINE SUBFACILITY.

     (A)   Subject to the terms and conditions hereof, if necessary to meet
Borrower's funding deadlines, NationsBank agrees to make Swing Line Loans to
Borrower at any time on or prior to the Swing Line Maturity Date, not to exceed
an amount at any one time outstanding equal to the lesser of (i) $50,000,000,
and (ii) the difference between the Total Commitment and the Total Principal
Debt. Swing Line Loans shall constitute "Borrowings" for all purposes hereunder,
except that Swing Line Loans shall not be considered a utilization of any
Lender's Commitment.  Notwithstanding the foregoing, the Total Principal Debt
(including, without limitation, all Swing Line Loans) shall not at any time
exceed the Total Commitment.

     (B)   Each request for a Swing Line Loan shall be in an amount equal to
$1,000,000 or a greater integral multiple of $50,000.  Borrower may request a
Swing Line Loan by submitting a Borrowing Request to Administrative Agent and
NationsBank.  Such Borrowing Request must be received by Administrative Agent
and NationsBank no later than 11:00 a.m. on the Borrowing Date for such Swing
Line Loan, provided 

                                       17
<PAGE>
 
that Borrower shall have provided telephonic notice to Administrative Agent and
NationsBank no later than 11:00 a.m. on the Borrowing Date for such Swing Line
Loan. NationsBank shall make such Swing Line Loan available to Borrower in
Dallas, Texas at 1:00 p.m. on such Borrowing Date.

     (C)   If necessary to meet Borrower's funding deadlines, Administrative
Agent may treat any Borrowing Request as a request for a Swing Line Loan from
NationsBank and NationsBank may fund it as a Swing Line Loan. Within one (1)
Business Day after each Swing Line Loan is funded, NationsBank shall request
that each Lender, and each Lender shall, on the first (1st) Business Day after
such request is made, purchase a portion of any one or more Swing Line Loans in
an amount equal to such Lender's Pro Rata Part of such Swing Line Loans by
funding under such Lender's Revolving Credit Note, such purchase to be made in
accordance with the terms of SECTION 2.2 of this Agreement just as if such
Lender were funding directly to Borrower under its Revolving Credit Note (such
that all Lenders other than NationsBank shall fund only under their respective
Revolving Credit Note and not under the Swing Line Loan Note). Unless
Administrative Agent knew when NationsBank funded a Swing Line Loan that
Borrower had not satisfied the conditions in this Agreement to obtain a
Borrowing, each Lender's obligation to purchase an interest in all Swing Line
Loans shall be absolute and unconditional and shall not be affected by any
circumstance, including, without limitation (i) any set-off, counterclaim,
recoupment, defense, or other right which such Lender or any other Person may
have against NationsBank or any other Person for any reason whatsoever, (ii) the
occurrence or continuance of a Potential Default or Default or the termination
of any Lender's Commitment, (iii) the occurrence of any Material Adverse Event,
(iv) any breach of this Agreement or any other Loan Document by Borrower, any of
its Affiliates, Administrative Agent, or any other Lender, or (v) any other
circumstance, happening, or event whatsoever, whether or not similar to any of
the foregoing. Any portion of a Swing Line Loan not so purchased and converted
may be treated by NationsBank as a Borrowing which was not funded by the non-
purchasing Lenders as contemplated in SECTION 2.2(C) of this Agreement, and as a
funding by NationsBank under the Total Commitment in excess of NationsBank's
Commitment. Each Swing Line Loan, once so sold, shall cease to be a Swing Line
Loan for the purposes of this Agreement, but shall be a Borrowing made under the
Total Commitment and each Lender's Commitment.

     2.5   COMPETITIVE BID SUBFACILITY.

     (A)   In addition to Borrowings otherwise provided for herein, but subject
to the terms and conditions of the Loan Documents, Borrower may, as set forth in
this SECTION 2.5, request Lenders to make offers to make Competitive Borrowings
under the Total Commitment. Lenders may, but shall have no obligation to, make
any such offers, and Borrower may, but shall have no obligation to, accept any
such offers. Any Competitive Borrowings made available to Borrower hereunder
shall be subject, however, to the conditions that on any date of determination:
(i) the aggregate principal outstanding under all Competitive Borrowings made by
all Lenders shall not exceed $100,000,000; (ii) on any date of determination,
the Principal Debt of all Borrowings (whether under the Competitive Bid
Subfacility, the Swing Line Subfacility, or otherwise) shall not exceed the
Total Commitment; and (iii) each Borrowing under the Competitive Bid Subfacility
must occur on a Business Day and prior to the Business Day immediately preceding
the Termination Date.

     (B)   In order to request Competitive Bids, Borrower shall deliver a
Competitive Bid Request to Administrative Agent no later than 10:00 a.m. Dallas,
Texas time (i) on the fifth (5th) Business Day preceding the Borrowing Date for
any requested Competitive Borrowing that will be comprised of Eurodollar
Borrowings, or (ii) not later than 9:00 a.m. Dallas, Texas time one (1) Business
Day before the Borrowing Date for any requested Competitive Borrowing that will
be comprised of Fixed Rate Borrowings. A Competitive Bid Request that does not
conform substantially to the format of EXHIBIT B-2 may be rejected by
Administrative Agent, and Administrative Agent shall promptly notify Borrower of
such rejection. Each

                                       18
<PAGE>
 
Competitive Bid Request shall refer to this Agreement and shall specify (i)
whether the Competitive Borrowing then being requested will be comprised of
Eurodollar Borrowings or Fixed Rate Borrowings, (ii) the Borrowing Date of such
Competitive Borrowing (which shall be a Business Day) and the aggregate
principal amount thereof (which shall not be less than $10,000,000 or a greater
integral multiple of $1,000,000), and (iii) the Interest Period with respect
thereto (which may not be more than six (6) months and which may not extend
beyond the Conversion Date). Promptly after its receipt of a Competitive Bid
Request that is not rejected as aforesaid, Administrative Agent shall notify
Lenders of the Competitive Bid Request on a form substantially similar to
EXHIBIT B-2, pursuant to which Lenders are invited to bid, subject to the terms
and conditions of this Agreement, to make Competitive Borrowings pursuant to
such Competitive Bid Request. Notwithstanding the foregoing, Administrative
Agent shall have no obligation to invite any Lender to make a Competitive Bid
pursuant to this SECTION 2.5 until such Lender has delivered a completed
Administrative Questionnaire to Administrative Agent.

     (C)   Each Lender may make one (1) or more Competitive Bids to Borrower
responsive to each respective Competitive Bid Request.  Each Competitive Bid by
a Lender must be received by Administrative Agent substantially in the form of
EXHIBIT F, (i) no later than 11:00 a.m. Dallas, Texas time on the fourth (4th)
Business Day preceding the Borrowing Date for any requested Competitive
Borrowing that will be comprised of Eurodollar Borrowings, or (ii) prior to 9:00
a.m. Dallas, Texas time on the Borrowing Date for any requested Competitive
Borrowing that will be comprised of Fixed Rate Borrowings.  Competitive Bids
that do not conform substantially to the format of EXHIBIT F may be rejected by
Administrative Agent after conferring with, and upon the instruction of,
Borrower, and Administrative Agent shall notify the appropriate Lender of such
rejection as soon as practicable.  Each Competitive Bid shall refer to this
Agreement and shall (x) specify the principal amount (which shall be in a
minimum principal amount of $5,000,000 or a greater integral multiple of
$1,000,000 and which may equal the entire principal amount of the Competitive
Borrowing requested by Borrower and may exceed such Lender's Commitment, subject
to the limitations set forth in SECTION 2.5(A)) of the Competitive Borrowing
such Lender is willing to make to Borrower, (y) specify the Competitive Bid Rate
at which such Lender is prepared to make its Competitive Borrowing, and (z)
confirm the Interest Period with respect thereto specified by Borrower in its
Competitive Bid Request.  A Competitive Bid submitted by a Lender pursuant to
this SECTION 2.5(C) shall be irrevocable.

     (D)   Administrative Agent shall promptly notify Borrower of all
Competitive Bids made and the Competitive Bid Rate and the principal amount of
each Competitive Borrowing in respect of which a Competitive Bid was made and
the identity of the Lender that made each bid.

     (E)   Borrower may, subject only to the provisions of this SECTION 2.5(E),
accept or reject any or all of the Competitive Bids referred to in SECTION
2.5(C); provided, however, that the aggregate amount of the Competitive Bids so
accepted by Borrower may not exceed the principal amount of the Competitive
Borrowing requested by Borrower (subject to the further limitations of SECTION
2.5(A)).  Borrower shall notify Administrative Agent whether and to what extent
it has decided to accept or reject any or all of the bids referred to in SECTION
2.5(C) (i) not later than 10:00 a.m. Dallas, Texas time three (3) Business Days
before the Borrowing Date specified for a proposed Competitive Borrowing that is
deemed a Eurodollar Borrowing or (ii) not later than 10:00 a.m., Dallas, Texas
time on the day specified for a proposed Competitive Borrowing that is deemed a
Fixed Rate Borrowing; provided, however, that (A) the failure by Borrower to
give such notice shall be deemed to be a rejection of all the bids referred to
in SECTION 2.5(C), (B) Borrower shall not accept a bid in the same or lower
principal amount made at a particular Competitive Bid Rate if Borrower has
decided to reject a bid made at a lower Competitive Bid Rate, (C) if Borrower
shall accept bids made at a particular Competitive Bid Rate but shall be
restricted by other conditions hereof from borrowing the principal amount of the
Competitive Borrowing in respect of which bids at such Competitive Bid Rate have
been made, then Borrower shall accept a ratable portion of each bid made at such
Competitive Bid Rate based as nearly 

                                       19
<PAGE>
 
as possible on the respective principal amounts of the Competitive Borrowing for
which such bids were made, and (D) no bid shall be accepted for a Competitive
Borrowing unless the aggregate principal amount to be funded pursuant to all
accepted bids hereunder shall be in a minimum amount of $10,000,000 or a greater
integral multiple of $1,000,000 for each respective Lender whose bid is
accepted. Notwithstanding the foregoing, if it is necessary for Borrower to
accept a ratable allocation of the bids made in response to a Competitive Bid
Request (whether pursuant to the events specified in CLAUSE (Y) above or
otherwise) and the available principal amount of the Competitive Borrowing to be
allocated among the Lenders submitting Competitive Bids is not sufficient to
enable Competitive Borrowings to be allocated to each such Lender in a minimum
principal amount of $10,000,000 or a greater integral multiple of $1,000,000,
then Borrower shall select the Lenders to be allocated such Competitive
Borrowings and shall round allocations up or down to the next higher or lower
multiple of $500,000 as it shall deem appropriate. A notice given by Borrower
pursuant to this SECTION 2.5(E) shall be irrevocable.

     (F)   Administrative Agent shall promptly notify each bidding Lender
whether or not its Competitive Bid has been accepted (which notice to such
Lenders whose Competitive Bids have been accepted will be given within one (1)
hour (except in the case of Fixed Rate Borrowings, in which case as soon as
possible) from the time such bid was accepted by Borrower and shall further
indicate in what amount and at what Competitive Bid Rate), and each successful
bidder will thereupon become bound, subject to the other applicable conditions
hereof, to advance the Competitive Borrowing in respect of which its bid has
been accepted. After completing the notifications referred to in the immediately
preceding sentence, Administrative Agent shall notify each bidding Lender of the
aggregate principal amount of all Competitive Bids accepted for and the range of
Competitive Bid Rates submitted in connection with that Competitive Borrowing.

     (G)   If Administrative Agent shall at any time elect to submit a
Competitive Bid in its capacity as a Lender, then it shall submit such bid
directly to Borrower one-half hour earlier than the latest time at which the
other Lenders are required to submit their bids to Administrative Agent pursuant
to SECTION 2.5(C).

     (H)   The Principal Debt of each Competitive Borrowing and all unpaid
interest thereon shall be due and payable on the last day of the applicable
Interest Period; provided that if Borrower fails to repay any Competitive
Borrowing on such day, then Borrower shall be deemed to have given a Notice of
Borrowing requesting Lenders to make a Borrowing hereunder in the amount of such
Competitive Borrowing, subject to satisfaction of the conditions specified in
SECTION 5; provided that failure to repay such Competitive Borrowing on the last
day of the applicable Interest Period shall not constitute a failure to satisfy
such conditions.

SECTION 3  TERMS OF PAYMENT.
- ---------  ---------------- 

     3.1   NOTES AND PAYMENTS.

     (A)   The Principal Debt (other than Competitive Borrowings and under the
Swing Line Loan) shall be evidenced by the Revolving Credit Notes, one payable
to each Lender in the stated principal amount of its Commitment. The Principal
Debt of all Competitive Borrowings shall be evidenced by the Competitive Bid
Notes. The Principal Debt under the Swing Line Loan shall be evidenced by the
Swing Line Note.

     (B)   Borrower must make each payment and prepayment on the Obligation,
without offset, counterclaim, or deduction, to Administrative Agent's principal
office in Dallas, Texas, in funds that will be available for immediate use by
Administrative Agent by 12:00 noon on the day due.  Payments received after such
time shall be deemed received on the next Business Day. Administrative Agent
shall pay to each Lender any payment to which such Lender is entitled on the
same day Administrative Agent receives the funds from

                                       20
<PAGE>
 
Borrower if Administrative Agent receives the payment or prepayment before 12:00
noon, and otherwise before 12:00 noon on the following Business Day. If and to
the extent that Administrative Agent does not make payments to Lenders when due,
then unpaid amounts shall accrue interest at the Federal Funds Rate from the due
date until (but not including) the payment date.

     3.2   INTEREST AND PRINCIPAL PAYMENTS.

     (A)   INTEREST PAYMENTS.  Accrued interest on each Borrowing (other than
Competitive Borrowings) is due and payable monthly as it accrues on the first
(1st) day of each month during the term hereof (commencing on September 1, 1998)
and on the Termination Date.  Accrued interest on each Competitive Borrowing is
due and payable on the last day of its respective Interest Period; provided that
if any such Interest Period is a period greater than three (3) months, then
accrued interest on such Competitive Borrowing shall also be due and payable on
the date ending each three (3) month period after the commencement of such
Interest Period.

     (B)   PRINCIPAL PAYMENTS.  The Total Principal Debt is due and payable on
the Termination Date.

     (C)   VOLUNTARY PREPAYMENT.  Borrower may voluntarily repay or prepay all
or any part of the Total Principal Debt at any time without premium or penalty,
subject to the following conditions:

          (I)    Administrative Agent must receive Borrower's written payment
     notice by 11:00 a.m. on (A) the Business Day preceding the date of payment
     of a Eurodollar Borrowing and (B) the Business Day preceding the date of
     payment of a Base Rate Borrowing, which shall specify the payment date and
     the Type and amount of the Borrowing(s) to be paid, and which shall
     constitute an irrevocable and binding obligation of Borrower to make a
     repayment or prepayment on the designated date;

          (II)   each partial repayment or prepayment must be in a minimum
     amount of at least $1,000,000 or a greater integral multiple of $100,000,
     or, if less, the Total Principal Debt; and

          (III)  Borrower shall pay any related Funding Loss upon demand.

Notwithstanding anything contained herein to the contrary, Borrower shall not
voluntarily prepay any Competitive Borrowing prior to the last day of the
Interest Period therefor.

     3.3   INTEREST OPTIONS.  Except as specifically otherwise provided,
Borrowings (other than Competitive Borrowings) shall bear interest at an annual
rate equal to the lesser of (a) the Base Rate plus the Applicable Margin, or,
except for Swing Line Loans, the Eurodollar Rate plus the Applicable Margin (in
each case as designated or deemed designated by Borrower and, in the case of
Eurodollar Borrowings, for the Interest Period designated by Borrower), and (b)
the Maximum Rate.  Except as specifically otherwise provided, Competitive
Borrowings shall bear interest at an annual rate of interest equal to the lesser
of (i) the Competitive Bid Rate, and (ii) the Maximum Rate.  Each change in the
Base Rate and Maximum Rate is effective, without notice to Borrower or any other
Person, upon the effective date of such change.

     3.4   QUOTATION OF RATES.  A Representative of Borrower may call
Administrative Agent before delivering a Borrowing Request to receive an
indication of the interest rates then in effect, but the indicated rates do not
bind Administrative Agent or Lenders or affect the interest rate that is
actually in effect when Borrower delivers its Borrowing Request or on the
Borrowing Date.

                                       21
<PAGE>
 
     3.5   DEFAULT RATE.  If permitted by Law, all past-due Principal Debt and
past-due interest accruing on any of the foregoing, bears interest from the date
due (stated or by acceleration) at the Default Rate until paid, regardless
whether payment is made before or after entry of a judgment.

     3.6   INTEREST RECAPTURE.  If the designated interest rate applicable to
any Borrowing exceeds the Maximum Rate, the interest rate on that Borrowing is
limited to the Maximum Rate, but any subsequent reductions in the designated
rate shall not reduce the interest rate thereon below the Maximum Rate until the
total amount of accrued interest equals the amount of interest that would have
accrued if that designated rate had always been in effect. If at maturity
(stated or by acceleration), or at final payment of the Notes, the total
interest paid or accrued is less than the interest that would have accrued if
the designated rates had always been in effect, then, at that time and to the
extent permitted by applicable Law, Borrower shall pay an amount equal to the
difference between (a) the lesser of the amount of interest that would have
accrued if the designated rates had always been in effect and the amount of
interest that would have accrued if the Maximum Rate had always been in effect,
and (b) the amount of interest actually paid or accrued on the Notes.

     3.7   INTEREST CALCULATIONS.

     (A)   Interest will be calculated on the basis of actual number of days
elapsed (including the first day but excluding the last day) but computed as if
each calendar year consisted of 360 days for all Borrowings (unless the
calculation would result in an interest rate greater than the Maximum Rate, in
which event interest will be calculated on the basis of a year of 365 or 366
days, as the case may be). All interest rate determinations and calculations by
Administrative Agent are conclusive and binding absent manifest error.

     (B)   The provisions of this Agreement relating to calculation of the Base
Rate, the Eurodollar Rate, and the Competitive Bid Rate are included only for
the purpose of determining the rate of interest or other amounts to be paid
under this Agreement that are based upon those rates.  Each Lender may fund and
maintain its funding of all or any part of each Borrowing as it selects.

     3.8   MAXIMUM RATE.  Regardless of any provision contained in any Loan
Document or any document related thereto, it is the intent of the parties to
this Agreement that no Agent or any Lender contract for, charge, take, reserve,
receive, or apply, as interest on all or any part of the Obligation any amount
in excess of the Maximum Rate or the Maximum Amount or receive any unearned
interest in violation of any applicable Law, and, if Lenders ever do so, then
any excess shall be treated as a partial repayment or prepayment of principal
and any remaining excess shall be refunded to Borrower. In determining if the
interest paid or payable exceeds the Maximum Rate, Borrower and Lenders shall,
to the maximum extent permitted under applicable Law, (a) treat all Borrowings
as but a single extension of credit (and Lenders and Borrower agree that is the
case and that provision in this Agreement for multiple Borrowings is for
convenience only), (b) characterize any non-principal payment as an expense,
fee, or premium rather than as interest, (c) exclude voluntary repayments or
prepayments and their effects, and (d) amortize, prorate, allocate, and spread
the total amount of interest throughout the entire contemplated term of the
Obligation. However, if the Obligation is paid in full before the end of its
full contemplated term, and if the interest received for its actual period of
existence exceeds the Maximum Amount, then Lenders shall refund any excess (and
Lenders may not, to the extent permitted by Law, be subject to any penalties
provided by any Laws for contracting for, charging, taking, reserving or
receiving interest in excess of the Maximum Amount). If the Laws of the State of
Texas are applicable for purposes of determining the "Maximum Rate" or the
"Maximum Amount," then those terms mean the "weekly ceiling" from time to time
in effect under Article 5069-1D.009, Title 79, Revised Civil Statutes of Texas,
as amended. Borrower agrees that Chapter 346 of the Texas Finance Code, as
amended (which regulates certain revolving credit loan accounts and revolving
tri-party accounts), does not apply to the Obligation.

                                       22
<PAGE>
 
     3.9   INTEREST PERIODS.  When Borrower requests any Eurodollar Borrowing or
a Fixed Rate Borrowing, Borrower may elect the applicable interest period (each
an "INTEREST PERIOD"), which may be, at Borrower's option, one (1), two (2),
three (3) or six (6) months for Eurodollar Borrowings and any period of up to
six (6) months (with respect to any Fixed Rate Borrowing), subject to the
following conditions: (a) the initial Interest Period for a Eurodollar Borrowing
commences on the applicable Borrowing Date or conversion date, and each
subsequent Interest Period applicable to any Borrowing commences on the day when
the next preceding applicable Interest Period expires; (b) if any Interest
Period for a Eurodollar Borrowing begins on a day for which there exists no
numerically corresponding Business Day in the calendar month at the end of the
Interest Period ("ENDING CALENDAR MONTH"), then the Interest Period ends on the
next succeeding Business Day of the Ending Calendar Month, unless there is no
succeeding Business Day in the Ending Calendar Month in which case the Interest
Period ends on the next preceding Business Day of the Ending Calendar Month; (c)
no Interest Period for any portion of Principal Debt may extend beyond the
scheduled repayment date for that portion of Principal Debt; and (d) there may
not be in effect at any one time more than twelve (12) Interest Periods
(including, without limitation, Interest Periods for Competitive Borrowings).
Notwithstanding the foregoing, subject to the foregoing conditions and the
consent of Administrative Agent (such consent to be in Administrative Agent's
reasonable discretion), Borrower may, not more often than during four (4) thirty
(30) day periods during any twelve (12) month period during the term of this
Agreement in anticipation of Borrower's prepayment of Borrowings from equity or
debt offerings or financings, elect Interest Periods of seven (7) days, fourteen
(14) days, or twenty-one (21) days.

     3.10  CONVERSIONS.  Borrower may (a) on the last day of the applicable
Interest Period convert all or part of a Eurodollar Borrowing to a Base Rate
Borrowing, (b) at any time convert all or part of a Base Rate Borrowing to a
Eurodollar Borrowing, and (c) on the last day of an Interest Period, elect a new
Interest Period for a Eurodollar Borrowing. Any such conversion is subject to
the dollar limits and denominations of SECTION 2.1 and may be accomplished by
delivering a Borrowing Request to Administrative Agent no later than 11:00 a.m.
(i) on the third (3rd) Business Day before (A) the conversion date for
conversion to a Eurodollar Borrowing and (B) the last day of the Interest
Period, for the election of a new Interest Period, and (ii) one (1) Business Day
before the last day of the Interest Period for conversion to a Base Rate
Borrowing. Absent Borrower's notice of conversion or election of a new Interest
Period, a Eurodollar Borrowing shall be converted to a Base Rate Borrowing when
the applicable Interest Period expires.

     3.11  ORDER OF APPLICATION.

     (A)   If no Default exists, any payment shall be applied to the Obligation
in the order and manner as provided in this Agreement.

     (B)   If a Default exists, any payment (including proceeds from the
exercise of any Rights) shall be applied in the following order: (i) to all fees
and expenses for which Administrative Agent or Lenders have not been paid or
reimbursed in accordance with the Loan Documents (and if such payment is less
than all unpaid or unreimbursed fees and expenses, then the payment shall be
paid against unpaid and unreimbursed fees and expenses in the order of
incurrence or due date); (ii) to accrued interest on the Principal Debt; (iii)
to the Principal Debt of any Swing Line Loans; and (iv) to the remaining
Obligation in the order and manner as Administrative Agent deems appropriate.

     3.12  SHARING OF PAYMENTS, ETC.  If any Lender obtains any amount (whether
voluntary, involuntary or otherwise, including as a result of exercising its
Rights under SECTION 3.13) that exceeds the part of that payment that such
Lender is then entitled to receive under the Loan Documents, then such Lender
shall purchase from the other Lenders participations that will cause the
purchasing Lender to share the excess amount ratably with each other Lender. If
all or any portion of any excess amount is subsequently recovered 

                                       23
<PAGE>
 
from the purchasing Lender, then the purchase shall be rescinded and the
purchase price restored to the extent of the recovery. Borrower agrees that any
Lender purchasing a participation from another Lender under this SECTION may, to
the fullest extent permitted by Law, exercise all of its Rights of payment
(including the Right of offset) with respect to that participation as fully as
if such Lender were the direct creditor of Borrower in the amount of that
participation.

     3.13  OFFSET.  If a Default exists, then each Lender is entitled, but is
not obligated, to exercise (for the benefit of all Lenders in accordance with
SECTION 3.12) the Rights of offset and banker's Lien against each and every
account and other property, or any interest therein, that Borrower may now or
hereafter have with, or which is now or hereafter in the possession of, that
Lender to the extent of the full amount of the Obligation owed to it.

     3.14  BOOKING BORROWINGS.  To the extent permitted by Law, any Lender may
make, carry or transfer its Borrowings at, to, or for the account of any of its
branch offices or the office of any of its Affiliates.  However, no Affiliate is
entitled to receive any greater payment under SECTION 3.16 than the transferor
Lender would have been entitled to receive with respect to those Borrowings.

     3.15  BASIS UNAVAILABLE OR INADEQUATE FOR THE EURODOLLAR RATE.  If (a)
Administrative Agent determines that the basis for determining the applicable
rate is not available, or (b) any Lender determines that the resulting rate does
not accurately reflect the cost to such Lender of making or converting
Borrowings at that rate for the applicable Interest Period, then:

           (1) In the case of (A), Administrative Agent shall promptly notify
     Borrower and Lenders of that determination (which is conclusive and binding
     on Borrower absent manifest error), and all Borrowings shall bear interest
     at the sum of the Base Rate plus the Applicable Margin.  Until
     Administrative Agent notifies Borrower that such circumstances no longer
     exist, Lenders' commitments under this Agreement to make, or to convert to,
     Eurodollar Borrowings will be suspended.

           (2) In the case of (B), such Lender shall promptly notify
     Administrative Agent and Borrower, and all Borrowings of such Lender shall
     bear interest at the sum of the Base Rate plus the Applicable Margin.
     Until Administrative Agent notifies Borrower that such circumstances no
     longer exist, such Lender's commitment under this Agreement to make, or to
     convert to, Eurodollar Borrowings will be suspended.

     3.16  ADDITIONAL COSTS.  With respect to any Law, requirement, request,
directive, or change affecting banking institutions generally:

     (A)   EUROCURRENCY RESERVES.  If any Lender shall be required under any
Reserve Requirement to maintain reserves with respect to liabilities or assets
consisting of or including Eurocurrency Liabilities, then (i) such Lender
(through Administrative Agent) shall, within sixty (60) days after the end of
any Interest Period with respect to any Eurodollar Borrowing during which such
Lender was so required to maintain reserves, deliver to Borrower a certificate
stating (A) that such Lender was required to maintain reserves and as a result
such Lender incurred additional costs in connection with making Eurodollar
Borrowings and (B) in reasonable detail, such Lender's computations of the
amount of additional interest payable by Borrower, pursuant to the provisions
below, and (ii) Borrower shall, promptly upon receipt of any such certificate,
pay to Administrative Agent, for the account to such Lender, additional interest
on the unpaid principal amount of each Eurodollar Borrowing of such Lender made
to it outstanding during the Interest Period with respect to which the above-
referenced certificate was delivered to Administrative Agent, at a rate per
annum equal to 

                                       24
<PAGE>
 
the difference obtained by subtracting (x) the Eurodollar Rate for such Interest
Period from (y) the rate obtained by dividing such Eurodollar Rate by a
percentage equal to 100% minus the Reserve Requirement of such Lender for such
Interest Period. The amount of interest payable by Borrower to any Lender as
stated in any certificate delivered to Administrative Agent pursuant to the
provisions of this SECTION 3.16(A) shall be conclusive and binding for all
purposes, absent manifest error. The provisions of this SECTION 3.16(A) shall
survive the termination of this Agreement.

     (B)   RESERVES.  With respect to any Eurodollar Borrowing or any Fixed Rate
Borrowing, if (i) any change in present Law, any change in the interpretation or
application of any present Law, or any future Law imposes, modifies, or deems
applicable (or if compliance by any Lender with any such requirement of any
Tribunal results in) any such requirement that any reserves (including any
marginal, emergency, supplemental or special reserves) be maintained, and (ii)
those reserves reduce any sums receivable by such Lender under this Agreement or
increase the costs incurred by such Lender in advancing or maintaining any
portion of any Eurodollar Borrowing or any Fixed Rate Borrowing, then (unless
the effect is already reflected in the rate of interest then applicable under
this Agreement) such Lender (through Administrative Agent) shall deliver to
Borrower a certificate setting forth in reasonable detail the calculation of the
amount necessary to compensate it for its reduction or increase (which
certificate is conclusive and binding absent manifest error), and Borrower shall
promptly pay that amount to that Lender upon demand.  Such Lender shall notify
Administrative Agent and Borrower of any such determination as soon as
practicable (but in any event within 120 days) after such Lender obtains actual
knowledge of the event or condition prompting such Lender to make such
determination, and Borrower shall not be liable for any such amount or amounts
that accrue between the date such notification is required to be given and the
date notice was actually given.  The provisions of and undertakings and
indemnification set forth in this paragraph shall survive the satisfaction and
payment of the Obligation and termination of this Agreement.

     (C)   CAPITAL ADEQUACY.  With respect to any Borrowing, if any change in
present Law or any future Law regarding capital adequacy or compliance by
Administrative Agent or any Lender with any request, directive or requirement
now existing or hereafter imposed by any Tribunal regarding capital adequacy, or
any change in its written policies or in the risk category of this transaction,
reduces the rate of return on its capital as a consequence of its obligations
under this Agreement to a level below that which it otherwise could have
achieved (taking into consideration its policies with respect to capital
adequacy) by an amount deemed by it to be material (and it may, in determining
the amount, use reasonable assumptions and allocations of costs and expenses and
use any reasonable averaging or attribution method), then (unless the effect is
already reflected in the rate of interest then applicable under this Agreement)
Administrative Agent or such Lender (through Administrative Agent) shall notify
Borrower and deliver to Borrower a certificate setting forth in reasonable
detail the calculation of the amount necessary to compensate it (which
certificate is conclusive and binding absent manifest error), and Borrower shall
promptly pay that amount to Administrative Agent or such Lender upon demand.
Such Lender shall notify Administrative Agent and Borrower of any such
determination as soon as practicable (but in any event within 120 days) after
such Lender obtains actual knowledge  of the event or condition prompting such
Lender to make such determination, and Borrower shall not be liable for any such
amount or amounts that accrue between the date such notification is required to
be given and the date notice was actually given.  The provisions of and
undertakings and indemnification set forth in this paragraph shall survive the
satisfaction and payment of the Obligation and termination of this Agreement.

     (D)   TAXES.  Any Taxes payable by Administrative Agent or any Lender or
ruled (by a Tribunal) payable by Administrative Agent or any Lender in respect
of this Agreement or any other Loan Document shall, if permitted by Law, be paid
by Borrower, together with interest and penalties, if any (except for (i) (1)
Taxes imposed on or measured by the overall net income of Administrative Agent
or such Lender, (2) franchise or similar taxes of Administrative Agent or such
Lender, and (3) amounts requested to be 

                                       25
<PAGE>
 
withheld for Taxes pursuant to the last sentence of SECTION 3.19, and (ii) such
interest and penalties incurred as a result of the gross negligence or willful
misconduct of Administrative Agent or any Lender). Administrative Agent or such
Lender (through Administrative Agent) shall notify Borrower and deliver to
Borrower a certificate setting forth in reasonable detail the calculation of the
amount of payable Taxes, which certificate is conclusive and binding (absent
manifest error), and Borrower shall promptly pay that amount to Administrative
Agent for its account or the account of such Lender, as the case may be. If
Administrative Agent or such Lender subsequently receives a refund of the Taxes
paid to it by Borrower, then the recipient shall promptly pay the refund to
Borrower.

     3.17  CHANGE IN LAW.  If any Law makes it unlawful for any Lender to make
or maintain Eurodollar Borrowings, then such Lender shall promptly notify
Borrower and Administrative Agent, and (a) as to undisbursed funds, that
requested Borrowing shall be made as a Base Rate Borrowing, and (b) as to any
outstanding Borrowing, (i) if maintaining the Borrowing until the last day of
the applicable Interest Period is unlawful, the Borrowing shall be converted to
a Base Rate Borrowing as of the date of notice, and Borrower shall pay any
related Funding Loss, or (ii) if not prohibited by Law, the Borrowing shall be
converted to a Base Rate Borrowing as of the last day of the applicable Interest
Period, or (iii) if any conversion will not resolve the unlawfulness, then
Borrower shall promptly prepay the Borrowing, without penalty, together with any
related Funding Loss.

     3.18  FUNDING LOSS.  BORROWER AGREES TO INDEMNIFY EACH LENDER AGAINST, AND
PAY TO IT UPON DEMAND, ANY FUNDING LOSS OF EACH LENDER.  When any Lender demands
that Borrower pay any Funding Loss, such Lender shall deliver to Borrower and
Administrative Agent a certificate setting forth in reasonable detail the basis
for imposing Funding Loss and the calculation of the amount, which calculation
is conclusive and binding absent manifest error.  The provisions of and
undertakings and indemnification set forth in this paragraph shall survive the
satisfaction and payment of the Obligation and termination of this Agreement.

     3.19  FOREIGN LENDERS.  Each Lender that is organized under the Laws of any
jurisdiction other than the United States of America or any State thereof (a)
represents to Administrative Agent and Borrower that (i) no Taxes are required
to be withheld by Administrative Agent or Borrower with respect to any payments
to be made to it in respect of the Obligation, and (ii) it has furnished to
Administrative Agent and Borrower two duly completed copies of U.S. Internal
Revenue Service Form 4224, Form 1001, Form W-8, or any other tax form acceptable
to Administrative Agent (wherein it claims entitlement to complete exemption
from U.S. federal withholding tax on all interest payments under the Loan
Documents), and (b) covenants to (i) provide Administrative Agent and Borrower a
new tax form upon the expiration or obsolescence of any previously delivered
form according to Law, duly executed and completed by it, and (ii) comply from
time to time with all Laws with regard to the withholding tax exemption.  If any
of the foregoing is not true or the applicable forms are not provided, then
Borrower or Administrative Agent (without duplication) may deduct and withhold
from interest payments under the Loan Documents United States federal income tax
at the full rate applicable under the Code.

     3.20  EXTENSION OF TERMINATION DATE.  If no Default or Potential Default
exists, Borrower may request one-year extensions of the then-existing
Termination Date by making such request in writing (an "EXTENSION REQUEST") to
Administrative Agent between seventy-five (75) and ninety (90) days prior to the
date that is one (1) year prior to the then-existing Termination Date.  The
then-existing Termination Date shall be extended for one (1) year only if (i)
Administrative Agent and each Lender consent in writing to such extension within
thirty (30) days following the receipt of the Extension Request, and (ii)
Borrower pays to Administrative Agent the extension fee set forth in SECTION
4.4.  The failure to respond by Administrative Agent or any Lender to an
Extension Request shall be deemed to be a denial of such consent by such Person.

                                       26
<PAGE>
 
If Lenders having a Pro Rata Part of at least eighty percent (80%) consent to
such extension (such Lenders being "CONSENTING LENDERS" and the Lenders not
consenting being "NON-CONSENTING LENDERS"), then the Termination Date shall be
extended as to the Consenting Lenders provided that Borrower on or before the
then-current Termination Date either (a) pays to the Non-Consenting Lenders the
Principal Debt owing to such Non-Consenting Lenders, together with all interest
and fees owing to such Non-Consenting Lenders, in which case the Commitments of
such Non-Consenting Lenders shall be terminated, or (b) effects an assignment
from the Non-Consenting Lenders to a new Lender or Lenders pursuant to SECTION
13.10 who shall consent to the extension of the Termination Date.

     3.21  CONVERSION TO TERM LOAN.

     (A)   Subject to the terms and conditions of this Agreement, if any
Extension Request shall be denied as provided in SECTION 3.20, then, on the date
that is one (1) year prior to the then-existing Termination Date (the
"CONVERSION DATE"), Borrower may elect to convert the aggregate unpaid principal
amount of the Total Principal Debt (provided that any outstanding Swing Line
Loans shall be purchased and converted on or before the Conversion Date in
accordance with SECTION 2.4) outstanding on the Conversion Date (such amount
being the "ORIGINAL UNPAID PRINCIPAL BALANCE" into a term loan from each Lender
(each a "TERM LOAN" and collectively, the "TERM LOANS"), provided that (i) all
conditions precedent to a Borrowing set forth in SECTION 5 are satisfied as of
the Conversion Date, (ii) no Default exists, (iii) Borrower shall have delivered
to Administrative Agent a written request ("CONVERSION NOTICE") to convert the
Total Principal Debt to Term Loans at least thirty (30) days prior to the date
that is one (1) year prior to the then-current Termination Date, and (iv)
Borrower shall have paid the conversion fee set forth in SECTION 4.5.

     (B)   Upon the conversion of the Original Unpaid Principal Balance to the
Term Loans, the Commitments shall terminate and Borrower shall have no further
right to receive, and no Lender shall have the obligation to make, any
Borrowings or to extend the Termination Date beyond the scheduled maturity of
the Term Loans.

     (C)   If Borrower elects to convert the Original Unpaid Principal Balance
into Term Loans, then Borrower shall repay the principal balance of the Term
Loans in quarterly installments, commencing on the August 1 immediately
following the Conversion Date, and thereafter on the first (1st) day of each
succeeding November, February, May, and August. The amount of each quarterly
principal installment shall be equal to the following amount during the
corresponding period:

During the Second Year After the Conversion Date       An amount equal to the Original Unpaid
                                                       Principal Balance times 3.75%
- ------------------------------------------------------------------------------------------------
During the Third Year After the Conversion Date        An amount equal to the Original Unpaid
                                                       Principal Balance times 7.5%
================================================================================================

     (E)   If Borrower elects to convert the Original Unpaid Principal Balance
into Term Loans, then the unpaid principal balance of, and accrued interest on,
the Term Loans, together with all other amounts due under this Agreement, shall
be finally due and payable on the third (3rd) anniversary of the Conversion
Date.

     3.22   OPTION TO REPLACE LENDERS.  If any Lender shall make demand for
payment or reimbursement pursuant to SECTION 3.15(B) or SECTIONS 3.16(A), (B),
(C), or (D), or notify Borrower of the occurrence of the circumstances described
in SECTION 3.17, then, provided that (a) no Default has occurred and is
continuing, and (b) the circumstances resulting in such demand for payment or
reimbursement are not applicable to all Lenders, Borrower may terminate the
Commitment of such Lender, in whole but not in part, by either (i) (A) giving
such Lender and Administrative Agent not less than five (5) Business Days'
written notice thereof, which notice shall be irrevocable and effective only
upon receipt thereof by such Lender and Administrative Agent and shall specify
the date of such termination, and (B) paying such Lender (and there shall become
due and payable) on such date the outstanding Principal Debt of all Borrowings
made by such Lender, all interest thereon, and any other Obligation owed to such
Lender (including under SECTION 3.18), if any, or (ii) pursuant to the
provisions of SECTION 13.11, proposing the introduction of a replacement Lender
satisfactory to Administrative Agent, or obtaining the agreement of one or more
existing Lenders, to assume the entire amount of the Commitment of the Lender
whose Commitment is being terminated, on the effective date of such termination.
Upon the satisfaction of all of the foregoing conditions, such Lender that is
being terminated shall cease to be a "Lender" for purposes of this Agreement,
provided that Borrower shall continue to be obligated to such Lender under
SECTION 7.12 with respect to Indemnified Liabilities (as defined in SECTION
7.12) arising prior to such termination.

SECTION 4  FEES.
- ---------  ---- 

     4.1   TREATMENT OF FEES.  The fees described in this SECTION 4 (a) are not
compensation for the use, detention, or forbearance of money, (b) are in
addition to, and not in lieu of, interest and expenses otherwise described in
this Agreement, (c) are payable in accordance with SECTION 3.1(B), (d) are non-
refundable, (e) to the fullest extent permitted by Law, bear interest, if not
paid when due, at the Default Rate, and (f) are calculated on the basis of
actual number of days (including the first day but excluding the last day)
elapsed, but computed as if each calendar year consisted of 360 days, unless
computation would result in an interest rate in excess of the Maximum Rate in
which event the computation is made on the basis of a year of 365 or 366 days,
as the case may be.  The fees described in this SECTION 4 are in all events
subject to the provisions of SECTION 3.8.

     4.2   ADMINISTRATIVE AGENT FEES.  Borrower shall pay to Administrative
Agent, solely for its own account, the fees described in the letter agreement
between Borrower and Administrative Agent dated June 1, 1995.

     4.3   COMMITMENT FEES.

     (A)   On or before the date hereof, Borrower shall pay to Administrative
Agent, for the ratable account of Lenders, a commitment fee of $350,000.00.
Such fee shall be in lieu of the extension fee required by Section 4.4 of the
Third Restated Credit Agreement.

     (B)   Borrower agrees to pay to Administrative Agent for the ratable
account of Lenders a commitment fee equal to the sum of the amounts obtained by
multiplying each portion of the daily Unused 

                                       28
<PAGE>
 
Commitment times 0.15% per annum. Such commitment fee shall be due and payable
on the first (1st) day of each August, November, February, and May during the
term hereof, commencing on September 1, 1998, and on the Termination Date, based
upon the Unused Commitment for each day during the quarter ending on such date.
Solely for purposes of this SECTION 4.3(B) (A) determinations of the average
daily Unused Commitment shall exclude the Principal Debt of Competitive
Borrowings and Swing Line Loans; and (B) "ratable" means, for any calculation
period, with respect to any Lender, the proportion that (x) the average daily
unused Commitment of such Lender during the period bears to (y) the aggregate
amount of the average daily unused Total Commitment during the period.

     4.4   EXTENSION FEE.  Upon each extension of the Termination Date, as
provided in SECTION 3.20, Borrower agrees to pay Administrative Agent, on or
before the existing Termination Date, for the ratable account of Lenders, an
extension fee equal to one-tenth of one percent (.10%) of the Commitments of
Lenders.

     4.5   CONVERSION FEE.  Borrower agrees to pay to Administrative Agent, for
the ratable account of Lenders, a fee equal to one-quarter of one percent (.25%)
of the unpaid Principal Debt of the Term Loans (a) on the date that is the first
(1st) anniversary date of the Conversion Date if any portion of the Term Loans
is unpaid on that date, and (b) on the date that is the second (2nd) anniversary
of the Conversion Date if any portion of the Term Loans is unpaid on that date.

     4.6   COMPETITIVE BID FEE.  Each Competitive Bid Request hereunder
submitted by Borrower to Administrative Agent shall be accompanied by a
competitive bid fee of $1,500 (payable solely to Administrative Agent for its
own account) and shall only request bids for a single Borrowing Date.

SECTION 5  CONDITIONS PRECEDENT.  Administrative Agent will not be obligated to
- ---------  --------------------                                                
fund the initial Borrowing unless Administrative Agent has timely received (a) a
Borrowing Request, and (b) all of the items described on SCHEDULE 5. In
addition, Administrative Agent will not be obligated to make any Borrowing
(including any Competitive Borrowing), unless on the applicable Borrowing Date
(and after giving effect to the requested Borrowing): (i) Administrative Agent
shall have timely received a Borrowing Request or Notice of Competitive
Borrowing, as the case may be; (ii) Administrative Agent shall have received any
applicable fees; (iii) all of the representations and warranties of Borrower in
the Loan Documents are true and correct in all material respects (unless they
speak to a specific date or are based on facts which have changed by
transactions contemplated or permitted by this Agreement); (iv) no Default or
Potential Default exists; and (v) the funding of the Borrowing is permitted by
Law. Upon Administrative Agent's request, Borrower shall deliver to
Administrative Agent evidence substantiating any of the matters in the Loan
Documents that are necessary to enable Borrower to qualify for the Borrowing.
Each condition precedent in this Agreement (including those on SCHEDULE 5) is
material to the transactions contemplated by this Agreement, and time is of the
essence with respect to each condition precedent. Administrative Agent may fund
any Borrowing without all conditions being satisfied, but, to the extent
permitted by Law, that funding and issuance shall not be deemed to be a waiver
of the requirement that each condition precedent be satisfied as a prerequisite
for any subsequent funding or issuance, unless Administrative Agent specifically
waives each item in writing.

SECTION 6  REPRESENTATIONS AND WARRANTIES.  Borrower represents and warrants to
- ---------  ------------------------------                                      
Agents and Lenders as follows:

     6.1   PURPOSE OF CREDIT FACILITY.  Borrower will use proceeds of the
Borrowings hereunder for working capital and general business purposes of
Borrower, its Consolidated Affiliates, and its Unconsolidated Affiliates.
Borrower is not engaged principally, or as one of its important activities, in
the business of extending credit for the purpose of purchasing or carrying any
"margin stock" within the meaning of Regulation U of the Board of Governors of
the Federal Reserve System, as amended. No part of the proceeds 

                                       29
<PAGE>
 
of any Borrowing will be used, directly or indirectly, for a purpose that
violates any Law, including the provisions of Regulation U.

     6.2   CORPORATE EXISTENCE, GOOD STANDING, AUTHORITY AND COMPLIANCE. Each of
Borrower and its Consolidated Affiliates is duly formed, validly existing, and
in good standing under the Laws of the jurisdiction in which it is incorporated
or formed as identified on SCHEDULE 6.2 (as supplemented from time to time).
Each of Borrower and its Consolidated Affiliates (a) is duly qualified to
transact business and is in good standing as a foreign trust, corporation,
partnership, limited liability company, or other entity in each jurisdiction
where the nature and extent of its business and properties require due
qualification and good standing, which jurisdictions are identified on SCHEDULE
6.2 (as supplemented from time to time), (b) possesses all requisite authority,
permits, and power to conduct its business as is now being, or is contemplated
by this Agreement to be, conducted, and (c) is in compliance with all applicable
Laws, except in any such case where violation of the foregoing could not
reasonably be expected to result in a Material Adverse Event.

     6.3   AFFILIATES.  As of the date of this Agreement, Borrower has no
Consolidated Affiliates or Unconsolidated Affiliates except as disclosed on
SCHEDULE 6.2 (as supplemented from time to time to reflect changes as a result
of transactions permitted by this Agreement).

     6.4   AUTHORIZATION AND CONTRAVENTION.  The execution and delivery by
Borrower of each Loan Document or related document to which it is a party and
the performance by it of its obligations thereunder (a) are within its trust
power, (b) have been duly authorized by all necessary trust action, (c) require
no action by or filing with any Tribunal (other than any action or filing that
has been taken or made on or before the date of this Agreement), (d) do not
violate any provision of its declaration of trust or bylaws, (e) do not violate
any provision of Law or order of any Tribunal applicable to it, (f) do not
violate any material agreements to which it is a party, or (g) do not result in
the creation or imposition of any Lien on any asset of Borrower or any
Consolidated Affiliate, except in such case where failure to do so could not
reasonably be expected to result in a Material Adverse Event.

     6.5   BINDING EFFECT.  Upon execution and delivery by all parties thereto,
each Loan Document to which it is a party will constitute a legal and binding
obligation of Borrower, enforceable against it in accordance with its terms,
subject to applicable Debtor Relief Laws and general principles of equity.

     6.6   FINANCIAL STATEMENTS; FISCAL YEAR.  The Current Financials were
prepared in accordance with GAAP (except that quarterly Financial Statements may
omit footnotes required by GAAP) and present fairly, in all material respects,
the consolidated financial condition, results of operations, and cash flows of
Borrower and its Consolidated Affiliates as of, and for the portion of the
fiscal year ending on the date or dates thereof (subject only to normal audit
adjustments). All material liabilities of Borrower and its Consolidated
Affiliates as of the date or dates of the Current Financials are reflected
therein or in the notes thereto. Except for transactions directly related to, or
specifically contemplated by, the Loan Documents or disclosed in the Current
Financials, no subsequent material adverse changes have occurred in the
consolidated financial condition of Borrower and its Consolidated Affiliates
from that shown in the Current Financials, nor has Borrower or any Consolidated
Affiliate incurred any subsequent material liability. The fiscal year of
Borrower and its Consolidated Affiliates ends on December 31.

     6.7   LITIGATION.  Except as disclosed on SCHEDULE 6.7 and as otherwise
disclosed pursuant to SECTION 7.1(D)(I), neither Borrower nor any of its
Consolidated Affiliates is subject to, or aware of the threat of, any Litigation
that is reasonably likely to be determined adversely to Borrower or such
Consolidated Affiliate or, if so adversely determined, is a Material Adverse
Event.  Except as permitted under SECTION 10.4, no outstanding and unpaid
judgments against Borrower or any of its Consolidated Affiliates exist.

                                       30

     6.8   TAXES.

     (A)   All Tax returns of Borrower and its Consolidated Affiliates required
to be filed have been filed (or extensions have been granted) before
delinquency, except for returns for which the failure to file could not
reasonably be expected to result in a Material Adverse Event, and all Taxes
imposed upon Borrower and its Consolidated Affiliates that are due and payable
have been paid before delinquency or are being contested in good faith by
appropriate proceedings diligently conducted and for which reserves in
accordance with GAAP or otherwise reasonably acceptable to Administrative Agent
have been provided.

     (B)   As of the date hereof, no United States federal income tax returns of
the "affiliated group" (as defined in the Code) of which Borrower is a member
have been examined and closed.  The members of such affiliated group have filed
all United States Federal income tax returns and all other material tax returns
which are required to be filed by them and have paid all taxes due pursuant to
such returns or pursuant to any assessment received by or any of them.  The
charges, accruals and reserves on the books of Borrower in respect of taxes or
other governmental charges are, in the opinion of Borrower, adequate.

     (C)   Borrower qualifies as a REIT.

     6.9   ENVIRONMENTAL MATTERS.  Except as disclosed on SCHEDULE 6.9, and
except for any of the following which could not reasonably be expected to result
in a Material Adverse Event, (a) no environmental condition or circumstance

Affiliates properties or operations, (b) neither Borrower nor any of its
Consolidated Affiliates has received any report of Borrower or any of its
Consolidated Affiliates' violation of any Environmental Law, (c) neither
Borrower nor any of its Consolidated Affiliates knows that any of Borrower or
its Consolidated Affiliates is under any obligation to remedy any violation of
any Environmental Law, or (d) no facility of Borrower or any of its Consolidated
Affiliates is used for, or to the knowledge of Borrower or any of its
Consolidated Affiliates has been used for, storage, treatment or disposal of any
Hazardous Substance, except for (i) the storage and use of cleaning and
maintenance materials, used and stored in commercially reasonable quantities and
in compliance with applicable Environmental Laws, and (ii) light manufacturing
and distribution activities of tenants, in compliance with applicable
Environmental Laws, provided that such tenants are not primarily engaged in the
treatment, processing, recycling or disposal of any Hazardous Substance, or for
any other use that would give rise to the release of any Hazardous Substance on
such facility. Each of Borrower and its Consolidated Affiliates has taken
prudent steps to determine that its properties and operations do not violate any
Environmental Law, other than violations that, individually or in the aggregate,
could not reasonably be expected to result in a Material Adverse Event.

     6.10  PENSION PLANS.  Except to the extent that any such termination,
liability, penalty, or fine would not (either individually or in the aggregate)
reasonably be expected to have a Material Adverse Event (a) no steps have been
taken to terminate any Pension Plan, and no contribution failure has occurred
with respect to any Pension Plan sufficient to give rise to a Lien under any
Applicable Pension Laws, (b) no condition exists or event or transaction has
occurred with respect to any Pension Plan which could reasonably be expected to
result in the incurrence by Borrower or any ERISA Affiliate of any material
liability with respect to any contribution thereto, fine, or penalty, and (c)
neither Borrower nor any ERISA Affiliate has any material contingent liability
with respect to any post-retirement benefit under a Pension Plan.

     6.11  PROPERTIES; LIENS.  Each of Borrower and its Consolidated Affiliates
has good title to all its property reflected on the Current Financials (except
for property that is obsolete or that has been disposed in the ordinary course
of business or, after the date of this Agreement, as otherwise permitted by
SECTION 8.10 or SECTION 8.11). Except for Permitted Liens and Liens on
Properties acquired by Borrower or a Consolidated 

                                       31
<PAGE>
 
Affiliate, provided that such Liens are not incurred in contemplation of
Borrower's or such Consolidated Affiliate's acquisition of such Properties, no
Lien exists on any Property of Borrower or any of its Consolidated Affiliates in
the Pool, and the execution, delivery, performance, or observance of the Loan
Documents will not require or result in the creation of any Lien on any of
Borrower's or any of its Consolidated Affiliates' Property in the Pool.

     6.12  LOCATIONS.  Borrower's chief executive office is located at the
address on SCHEDULE 6.12 (as supplemented from time to time).  Borrower's books
and records are located at its chief executive office.

amended, or the Public Utility Holding Company Act of 1935, as amended.

     6.14  TRANSACTIONS WITH AFFILIATES.  Except as disclosed on SCHEDULE 6.14
(as supplemented from time to time) (if the disclosures are approved by
Administrative Agent) or as permitted by SECTION 8.4, neither Borrower nor any
of its Consolidated Affiliates is a party to a material transaction with any of
its Affiliates, other than transactions in the ordinary course of business and
upon fair and reasonable terms not materially less favorable than it could
obtain or could become entitled to in an arm's-length transaction with a Person
that was not its Affiliate.

     6.15  LIABILITIES.  Except for transactions directly related to, or
specifically contemplated or permitted by, the Loan Documents, neither Borrower
nor any of its Consolidated Affiliates is an obligor on any Liabilities, other
than Liabilities set forth in the Current Financials.

     6.16  INSURANCE. Each of Borrower and its Consolidated Affiliates
maintains with financially sound, responsible, and reputable insurance companies
or associations (or, as to workers' compensation or similar insurance, with an
insurance fund or by self-insurance authorized by the jurisdictions in which it
operates) insurance concerning its properties and businesses against casualties
and contingencies and of types and in amounts (and with co-insurance and
deductibles) as is customary in the case of similar businesses.

     6.17  LABOR MATTERS.  No actual or, to Borrower's knowledge, threatened
strikes, labor disputes, slow downs, walkouts, or other concerted interruptions
of operations by the employees of Borrower or any of its Consolidated Affiliates
that could reasonably be expected to result in a Material Adverse Event exist.
All payments due from Borrower or any of its Consolidated Affiliates for
employee health and welfare insurance have been paid or accrued as a liability
on its books, other than any non-payment that are not, individually or
collectively, a Material Adverse Event.

     6.18  SOLVENCY.  On each Borrowing Date, Borrower is, and after giving
effect to the requested Borrowing will be, Solvent.

     6.19  FULL DISCLOSURE.  Each material fact or condition relating to the
financial condition or business of Borrower or any of its Consolidated
Affiliates which could reasonably be expected to result in a Material Adverse
Event has been disclosed to Administrative Agent.  All information previously
furnished, furnished on the date of this Agreement, and furnished in the future,
by Borrower or any of its Consolidated Affiliates to Administrative Agent in
connection with the Loan Documents (a) was, is, and will be, true and accurate
in all material respects or based on good faith estimates on the date the
information is stated or certified, and (b) did not, does not, and will not,
fail to state any material fact the omission of which would otherwise make any
such information materially misleading, in each case taken as a whole.

     6.20  EXEMPTION FROM ERISA; PLAN ASSETS.  The assets of Borrower are not

regulation) of any Pension Plan.

     6.21  INTERCREDITOR AGREEMENT. Borrower is aware of, and has been
furnished a copy of, the Intercreditor Agreement.

     6.22  MINORITY INTERESTS.  All Consolidated Affiliates of Borrower having
minority interests are set forth on SCHEDULE 6.22 (as supplemented from time to
time).

     6.23  YEAR 2000 COMPLIANCE.  Borrower has (a) initiated a review and
assessment of all areas within its and each of its Consolidated Affiliates'
business and operations (including those affected by suppliers and vendors) that
could be adversely affected by the "Year 2000 Problem" (that is, the risk that
computer applications used by Borrower or any of its Consolidated Affiliates (or
its suppliers and vendors) may be unable to recognize and perform properly date-
sensitive functions involving certain dates prior to and any date after December
31, 1999), (b) developed a plan and timeline for addressing the Year 2000
Problem on a timely basis, and (c) to date, implemented that plan in accordance
with that timetable. Borrower reasonably believes that all computer applications
(including those of its suppliers and vendors) that are material to its or any
of its Consolidated Affiliates' business and operations will on a timely basis
be able to perform properly date-sensitive functions for all dates before and
after January 1, 2000 (that is, be "Year 2000 compliant"), except to the extent
that a failure to do so could not reasonably be expected to have Material
Adverse Effect.

neither (a) stayed on appeal nor (b) diligently contested in good faith by
appropriate proceedings and adequate reserves have been set aside on its books
in accordance with GAAP.

     10.5    GOVERNMENT ACTION. (a) A final non-appealable order is issued by
any Tribunal (including the United States Justice Department) requiring Borrower
or any of its Consolidated Affiliates, to divest all or a substantial portion of
its assets under any antitrust, restraint of trade, unfair competition, industry
regulation or similar Laws, or (b) any Tribunal condemns, seizes, or otherwise
appropriates, or takes custody or control of all or any substantial portion of
the assets of Borrower and its Consolidated Affiliates, taken as a whole.

     10.6    MISREPRESENTATION.  Any material representation or warranty made by
Borrower contained in any Loan Document at any time proves to have been
incorrect in any material respect when made.

     10.7    DEFAULT UNDER OTHER AGREEMENTS.

     (A)     Borrower or any of its Consolidated Affiliates shall fail to make
any payment in respect of any Liability when due or within any applicable grace
period; provided that the failure of Borrower or any of its Consolidated
Affiliates to make any payment when due or within any applicable grace period in
respect of (i) any Recourse Debt arising in one or more related or unrelated
transactions in an aggregate principal amount not exceeding $10,000,000, and
(ii) any non-recourse Liabilities arising in one or more related or unrelated
transactions in an aggregate principal amount not exceeding $50,000,000, shall
not constitute a Default hereunder; or

     (B)     the acceleration of the maturity of any Liabilities of Borrower or
any of its Consolidated Affiliates or default shall occur in the payment of any
Liabilities of Borrower or any of its Consolidated Affiliates or in respect of
any note or credit agreement relating to any such Liabilities and such default
shall continue for more than the period of grace, if any, specified therein or
otherwise granted by the lender thereof; provided that the acceleration of the
maturity of (i) any Recourse Debt arising in one or more related or unrelated
transactions in an aggregate principal amount not exceeding $10,000,000, and
(ii) any non-recourse Liabilities arising in one or more related or unrelated
transactions in an aggregate principal amount not exceeding $50,000,000 shall
not constitute a Default hereunder;

     10.8    VALIDITY AND ENFORCEABILITY OF LOAN DOCUMENTS. Except in accordance
with its terms or as otherwise expressly permitted by this Agreement, any Loan
Document at any time after its execution and delivery ceases to be in full force
and effect in any material respect or is declared by a Tribunal to be null and

                                       43
<PAGE>
 
void or its validity or enforceability is contested by Borrower or Borrower
denies that it has any further liability or obligations under any Loan Document
to which it is a party.

     10.9    MANAGEMENT CHANGES.

     (A)     During any period of twelve (12) consecutive calendar months,
individuals who were directors or trustees of Borrower on the first day of such
period shall cease to constitute a majority of the board of directors or
trustees of Borrower; provided, however, that the directors or trustees of
Borrower may include new directors or trustees that (i) are an officer or
employee of an Affiliate, or (ii) that are required in order (as a practical
matter) for the majority of the board of directors or trustees of Borrower to be
independent directors or trustees.

     (B)     Borrower shall change its present executive management, which
change could result in a Material Adverse Event.

     10.10   Plan Assets.  The assets of Borrower at any time constitute "plan
assets" as defined in 29 C.F.R. (S) 2510.3-101(a)(1) (or any successor
regulation).

SECTION 11   RIGHTS AND REMEDIES.
- ----------   ------------------- 

     11. REMEDIES UPON DEFAULT.

     (A)     If a Default (i) occurs under SECTION 10.3(C) or (ii) occurs and is
continuing under SECTION 10.3(A), (B) OR (D), the commitment to extend credit
under this Agreement automatically terminates, the entire unpaid balance of the
Obligation automatically becomes due and payable without any action of any kind
whatsoever.

     (B)     If a Default occurs and is continuing, subject to the terms of
SECTION 12.3(B), Administrative Agent may do any one or more of the following:
(i) if the maturity of the Obligation has not already been accelerated under
SECTION 11.1(A), declare the entire unpaid balance of all or any part of the
Obligation immediately due and payable, whereupon it is due and payable; (ii)
terminate the commitments of Lenders to extend credit under this Agreement;
(iii) reduce any claim to judgment; (iv) to the extent permitted by Law,
exercise (or request each Lender to, and each Lender is entitled to, exercise)
the Rights of offset or banker's Lien against the interest of Borrower and its
Consolidated Affiliates in and to every account and other property of Borrower
and its Consolidated Affiliates that are in the possession of any Agent or any
Lender to the extent of the full amount of the Obligation (and to the extent
permitted by Law, Borrower and its Consolidated Affiliates are deemed directly
obligated to each Lender in the full amount of the Obligation for this purpose);
and (v) exercise any and all other legal or equitable Rights afforded by the
Loan Documents, the Laws of the State of Texas, or any other applicable
jurisdiction.

     11.2    WAIVERS. To the extent permitted by Law, Borrower waives
presentment and demand for payment, protest, notice of intention to accelerate,
notice of acceleration, and notice of protest and nonpayment, and agrees that
its liability with respect to all or any part of the Obligation is not affected
by any renewal or extension in the time of payment of all or any part of the
Obligation, by any indulgence, or by any release or change in any security for
the payment of all or any part of the Obligation.

     11.3    PERFORMANCE BY ADMINISTRATIVE AGENT.  If any covenant, duty, or
agreement of Borrower is not performed in accordance with the terms of the Loan
Documents, then Administrative Agent may, while a Default exists, at its option,
perform or attempt to perform that covenant, duty or agreement on behalf of

                                       44
<PAGE>
 
Borrower (and any amount expended by Administrative Agent in its performance or
attempted performance is payable by Borrower to Administrative Agent on demand,
becomes part of the Obligation, and bears interest at the Default Rate from the
date of Administrative Agent's expenditure until paid). However, no Agent or any
Lender assumes or shall have, except by its express written consent, any
liability or responsibility for the performance of any covenant, duty, or
agreement of Borrower.

     11.4    NOT IN CONTROL.  None of the covenants or other provisions
contained in any Loan Document shall, or shall be deemed to, give Agents or
Lenders the Right to exercise control over the assets (including real property),
affairs, or management of Borrower or any of its Consolidated Affiliates; the
power of Agents and Lenders is limited to the Right to exercise the remedies
provided in this SECTION 11.

     11.5    COURSE OF DEALING. The acceptance by Agents or Lenders of any
partial payment on the Obligation shall not be deemed to be a waiver of any
Default then existing. No waiver by Agents or Lenders of any Default shall be
deemed to be a waiver of any other then-existing or subsequent Default. No delay
or omission by Agents or Lenders in exercising any Right under the Loan
Documents will impair that Right or be construed as a waiver thereof or any
acquiescence therein, nor will any single or partial exercise of any Right
preclude other or further exercise thereof or the exercise of any other Right
under the Loan Documents or otherwise.

     11.6    CUMULATIVE RIGHTS. All Rights available to Agents and Lenders under
the Loan Documents are cumulative of and in addition to all other Rights granted
to Agents and Lenders at law or in equity, whether or not the Obligation is due
and payable and whether or not Agents or Lenders have instituted any suit for
collection, foreclosure, or other action in connection with the Loan Documents.

     11.7    APPLICATION OF PROCEEDS. Any and all proceeds ever received by
Agents or Lenders from the exercise of any Rights pertaining to the Obligation
shall be applied to the Obligation according to SECTION 3.11.

     11.8    DIMINUTION IN VALUE OF COLLATERAL.  No Agent or any Lender has any
liability or responsibility whatsoever for any diminution in or loss of value of
any collateral now or hereafter securing payment or performance of all or any
part of the Obligation (other than diminution in or loss of value caused by its
gross negligence or willful misconduct).

     11.9    CERTAIN PROCEEDINGS. Borrower will promptly execute and deliver, or
cause the execution and delivery of, all applications, certificates,
instruments, registration statements, and all other documents and papers
Administrative Agent or any Lender reasonably request in connection with the
obtaining of any consent, approval, registration, qualification, permit,
license, or authorization of any Tribunal or other Person necessary or
appropriate for the effective exercise of any Rights under the Loan Documents.
Because Borrower agrees that Agents' and Lenders' remedies at Law for failure of
Borrower to comply with the provisions of this paragraph would be inadequate and
that failure would not be adequately compensable in damages, Borrower agrees
that the covenants of this paragraph may be specifically enforced.

SECTION 12   AGENTS AND LENDERS.
- ----------   ------------------ 

     12.1    AGENTS.

     (A)     APPOINTMENT OF ADMINISTRATIVE AGENT.  Each Lender appoints
Administrative Agent (and Administrative Agent accepts appointment) as its
nominee and agent, in its name and on its behalf:  (i) to act as its nominee and
on its behalf in and under all Loan Documents; (ii) to arrange the means whereby
its funds 

                                       45
<PAGE>
 
are to be made available to Borrower under the Loan Documents; (iii) to take any
action that it properly requests under the Loan Documents (subject to the
concurrence of other Lenders as may be required under the Loan Documents or the
Intercreditor Agreement); (iv) to receive all documents and items to be
furnished to it under the Loan Documents; (v) to be the secured party,
mortgagee, beneficiary, recipient, and similar party in respect of any
collateral, if any, for the benefit of Lenders; (vi) to promptly distribute to
it all material information, requests, documents, and items received from
Borrower under the Loan Documents; (vii) to promptly distribute to it its
ratable part of each payment or prepayment (whether voluntary, as proceeds of
collateral upon or after foreclosure, as proceeds of insurance thereon, or
otherwise) in accordance with the terms of the Loan Documents; and (viii) to
deliver to the appropriate Persons requests, demands, approvals, and consents
received from it. However, Administrative Agent may not be required to take any
action that exposes it to personal liability or that is contrary to any Loan
Document or applicable Law.

     (B)     SUCCESSOR ADMINISTRATIVE AGENT. Administrative Agent may
voluntarily resign. If the initial or any successor Administrative Agent ever
ceases to be a party to this Agreement or if the initial or any successor
Administrative Agent ever resigns or is removed, then the successor
Administrative Agent shall be appointed as provided in the Intercreditor
Agreement. So long as no Default has occurred and is continuing, Borrower shall
have the right to consent to any successor Administrative Agent that is not a
Lender at the time of such appointment. Any successor Administrative Agent must
be a commercial bank having a combined capital and surplus of at least
$10,000,000,000 (as shown on its most recently published statement of condition)
and whose debt obligations (or whose parent's debt obligations) are rated not
less than investment grade or its equivalent by Moody's or S & P. Upon its
acceptance of appointment as successor Administrative Agent, the successor
Administrative Agent succeeds to and becomes vested with all of the Rights of
the prior Administrative Agent, and the prior Administrative Agent is discharged
from its duties and obligations of Administrative Agent under the Loan
Documents, and each Lender shall execute the documents that any Lender, the
resigning or removed Administrative Agent, or the successor Administrative Agent
reasonably request to reflect the change. After any Administrative Agent's
resignation as Administrative Agent under the Loan Documents, the provisions of
this section inure to its benefit as to any actions taken or not taken by it
while it was Administrative Agent under the Loan Documents.

     (C)     DOCUMENTATION AGENT.   Documentation Agent, in such capacity, shall
have no rights, duties, or obligations hereunder, except as specifically
provided in this Agreement.  Documentation Agent (a) may voluntarily resign by
notice to Administrative Agent, Lenders, and Borrower, and (b) shall resign upon
the request of the Required Lenders for cause.  Upon the resignation of
Documentation Agent, the Required Lenders may elect to designate a successor
Documentation Agent (which, if no Default or Potential Default exists, is
subject to Borrower's approval that may not be unreasonably withheld), which
must be a Lender who is a commercial bank having a combined capital and surplus
of at least $10,000,000,000 (as shown on its most recently published statement
of condition)and whose debt obligations (or whose parent's debt obligations) are
rated not less than investment grade or its equivalent by Moody's or S & P.

     (D)     SYNDICATION AGENT. Syndication Agent, in such capacity, shall have
no rights, duties, or obligations hereunder, except as specifically provided in
this Agreement. Syndication Agent (a) may voluntarily resign by notice to
Administrative Agent, Lenders, and Borrower, and (b) shall resign upon the
request of the Required Lenders for cause. Upon the resignation of Syndication
Agent, the Required Lenders may elect to designate a successor Syndication Agent
(which, if no Default or Potential Default exists, is subject to Borrower's
approval that may not be unreasonably withheld), which must be a Lender who is a
commercial bank having a combined capital and surplus of at least
$10,000,000,000 (as shown on its most recently published statement of
condition)and whose debt obligations (or whose parent's debt obligations) are
rated not less than investment grade or its equivalent by Moody's or S & P.

                                       46
<PAGE>
 
      12.2     DELEGATION OF DUTIES; RELIANCE. Lenders may perform any of their
duties or exercise any of their Rights under the Loan Documents by or through
Administrative Agent, and Lenders and Administrative Agent may perform any of
their duties or exercise any of their Rights under the Loan Documents by or
through their respective Representatives. Administrative Agent, Lenders, and
their respective Representatives (a) are entitled to rely upon (and shall be
protected in relying upon) any written or oral statement believed by it or them
to be genuine and correct and to have been signed or made by the proper Person
and, with respect to legal matters, upon opinion of counsel selected by
Administrative Agent or any Lender (but nothing in this CLAUSE (A) permits
Administrative Agent to rely on (i) oral statements if a writing is required by
this agreement or (ii) any other writing if a specific writing is required by
this agreement), (b) are entitled to deem and treat each Lender as the owner and
holder of its portion of the Obligation for all purposes until, written notice
of the assignment or transfer is given to and received by Administrative Agent
(and any request, authorization, consent, or approval of any Lender is
conclusive and binding on each subsequent holder, assignee, or transferee of or
Participant in such Lender's portion of the Obligation until that notice is
given and received), (c) are not deemed to have notice of the occurrence of a
Default unless a responsible officer of Administrative Agent, who handles
matters associated with the Loan Documents and transactions thereunder, has
actual knowledge or Administrative Agent has been notified by a Lender or
Borrower, and (d) are entitled to consult with legal counsel (including counsel
for Borrower), independent accountants, and other experts selected by
Administrative Agent and are not liable for any action taken or not taken in
good faith by it in accordance with the advice of counsel, accountants, or
experts.

      12.3     LIMITATION OF AGENTS' LIABILITY.

     (A)   EXCULPATION. No Agent or any of its Representatives will be liable
for any action taken or omitted to be taken by it or them under the Loan
Documents in good faith and believed by it or them to be within the discretion
or power conferred upon it or them by the Loan Documents or be responsible for
the consequences of any error of judgment (except for fraud, gross negligence,
or willful misconduct), and no Agent or any of its Representatives has a
fiduciary relationship with any Lender by virtue of the Loan Documents (but
nothing in this Agreement negates the obligation of Administrative Agent to
account for funds received by it for the account of any Lender).

     (B)   INDEMNITY. Unless indemnified to its satisfaction against loss, cost,
liability, and expense, Administrative Agent may not be compelled to do any act
under the Loan Documents or to take any action toward the execution or
enforcement of the powers thereby created or to prosecute or defend any suit in
respect of the Loan Documents. If Administrative Agent requests instructions
from Lenders, with respect to any act or action in connection with any Loan
Document, then Administrative Agent is entitled to refrain (without incurring
any liability to any Person by so refraining) from that act or action unless and
until it has received instructions. In no event, however, may Administrative
Agent or any of its Representatives be required to take any action that it or
they determine could incur for it or them criminal or onerous civil liability.
Without limiting the generality of the foregoing, no Lender has any right of
action against Administrative Agent as a result of Administrative Agent's acting
or refraining from acting under this Agreement in accordance with instructions
of Required Lenders.

     (C)   RELIANCE. Administrative Agent is not responsible to any Lender or
any Participant for, and each Lender represents and warrants that it has not
relied upon Administrative Agent in respect of, (i) the creditworthiness of
Borrower and its Consolidated Affiliates and the risks involved to such Lender,
(ii) the effectiveness, enforceability, genuineness, validity, or the due
execution of any Loan Document (except by Administrative Agent), (iii) any
representation, warranty, document, certificate, report, or statement made
therein (except by Administrative Agent) or furnished thereunder or in
connection therewith, (iv) the adequacy of any collateral now or hereafter
securing the Obligation or the existence, priority, or perfection of any Lien

                                       47
<PAGE>
 
now or hereafter granted or purported to be granted on the collateral under any
Loan Document, or (v) observation of or compliance with any of the terms,
covenants, or conditions of any Loan Document on the part of Borrower and its
Consolidated Affiliates. EACH LENDER AGREES TO INDEMNIFY ADMINISTRATIVE AGENT
AND ITS REPRESENTATIVES AND HOLD THEM HARMLESS FROM AND AGAINST (BUT LIMITED TO
SUCH LENDER'S PRO RATA PART OF) ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES,
DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, REASONABLE EXPENSES, AND
REASONABLE DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER THAT MAY BE IMPOSED
ON, ASSERTED AGAINST, OR INCURRED BY THEM IN ANY WAY RELATING TO OR ARISING OUT
OF THE LOAN DOCUMENTS OR ANY ACTION TAKEN OR OMITTED BY THEM UNDER THE LOAN
DOCUMENTS IF ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES ARE NOT REIMBURSED FOR
SUCH AMOUNTS BY BORROWER. ALTHOUGH ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES
                          ----------------------------------------------------- 
HAVE THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR THEIR OWN
- --------------------------------------------------------------------------
ORDINARY NEGLIGENCE, ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES DO NOT HAVE
- -------------------                                                          
THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR THEIR OWN FRAUD,
GROSS NEGLIGENCE, OR WILLFUL MISCONDUCT.

      12.4     LIMITATION OF LIABILITY. No Lender or any Participant will incur
any liability to any other Lender or Participant except for acts or omissions in
bad faith, and neither Administrative Agent nor any Lender or Participant will
incur any liability to any other Person for any act or omission of any other
Lender or any Participant.

      12.5     INTERCREDITOR AGREEMENT. Administrative Agent and Lenders agree
that, so long as no Default has occurred and is continuing, they will not amend
or modify SECTION 2.03 or the related definitions therein (including the
definition of "Required Lenders") of the Intercreditor Agreement without the
prior written consent of Borrower, which consent shall not be unreasonably
withheld.

      12.5     CONFIRMATION OF INTERCREDITOR AGREEMENT. Agents and Lenders
hereby (a) confirm the terms, conditions, rights, and obligations set forth in
the Intercreditor Agreement and (b) that all references to the "Credit
Agreement" in the Intercreditor Agreement shall be to this Agreement, as
modified, amended, extended, or restated from time to time.

SECTION 13  MISCELLANEOUS.
- ----------  ------------- 

      13.1     HEADINGS. The headings, captions, and arrangements used in any of
the Loan Documents are, unless specified otherwise, for convenience only and
shall not be deemed to limit, amplify, or modify the terms of the Loan
Documents, nor affect the meaning thereof.

      13.2     NONBUSINESS DAYS; TIME. Any payment or action that is due under
any Loan Document on a non-Business Day may be delayed until the next-succeeding
Business Day (but interest shall continue to accrue on any applicable payment
until payment is in fact made) unless the payment concerns a Eurodollar
Borrowing, in which case if the next-succeeding Business Day is in the next
calendar month, then such payment shall be made on the next-preceding Business
Day.

      13.3     COMMUNICATIONS. Unless otherwise specifically provided, whenever
any Loan Document requires or permits any consent, approval, notice, request,
demand, or other communication from one party to another, communication must be
in writing (which may be by telex or telecopy) to be effective and shall be
deemed to have been given (a) if by telex, when transmitted to the appropriate
telex number and the appropriate answerback is received, (b) if by telecopy,
when transmitted to the appropriate telecopy number (and all communications sent
by telecopy must be confirmed promptly thereafter by telephone; but any
requirement in this parenthetical shall not affect the date when the telecopy
shall be deemed to have been 

                                       48
<PAGE>
 
delivered), (c) if by mail, on the fifth (5th) Business Day after it is enclosed
in an envelope and properly addressed, stamped, sealed, certified mail, return
receipt requested, and deposited in the appropriate official postal service, or
(d) if by any other means, when actually delivered. Until changed by notice
pursuant to this Agreement, the address (and telecopy number) for each party to
a Loan Document is set forth on SCHEDULE 1.

      13.4     FORM AND NUMBER OF DOCUMENTS. The form, substance, and number of
counterparts of each writing to be furnished under this Agreement must be
satisfactory to Administrative Agent and its counsel.

      13.5     SURVIVAL. All covenants, agreements, undertakings,
representations, and warranties made in any of the Loan Documents survive all
closings under the Loan Documents and, except as otherwise indicated, are not
affected by any investigation made by any party.

      13.6     GOVERNING LAW. Except as expressly provided in a Loan Document,
the Laws (other than conflict-of-laws provisions) of the State of Texas and of
the United States of America govern the Rights and duties of the parties to the
Loan Documents and the validity, construction, enforcement, and interpretation
of the Loan Documents.

      13.7     INVALID PROVISIONS. Any provision in any Loan Document held to be
illegal, invalid or unenforceable is fully severable; the appropriate Loan
Document shall be construed and enforced as if that provision had never been
included; and the remaining provisions shall remain in full force and effect and
shall not be affected by the severed provision. Agents, Lenders, and Borrower
agree to negotiate, in good faith, the terms of a replacement provision as
similar to the severed provision as may be possible and be legal, valid and
enforceable. However, if the provision held to be illegal, invalid or
unenforceable is a material part of this Agreement, such invalid, illegal or
unenforceable provision shall be, to the extent permitted by Law, replaced by a
clause or provision judicially construed and interpreted to be as similar in
substance and content to the original terms of such illegal, invalid or
unenforceable clause or provision as the context thereof would reasonably allow,
so that such clause or provision would thereafter be legal, valid and
enforceable.

      13.8     VENUE; SERVICE OF PROCESS; JURY TRIAL. EACH PARTY TO ANY LOAN
DOCUMENT, IN EACH CASE FOR ITSELF, ITS SUCCESSORS AND ASSIGNS (AND IN THE CASE
OF BORROWER, FOR EACH OF ITS CONSOLIDATED AFFILIATES), (a) IRREVOCABLY SUBMITS
TO THE NONEXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS OF THE STATE OF
TEXAS, (b) IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY
OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY
LITIGATION ARISING OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS AND THE
OBLIGATION BROUGHT IN DISTRICT COURTS OF DALLAS OR HARRIS COUNTY, TEXAS, OR IN
THE UNITED STATES DISTRICT COURT FOR THE NORTHERN OR SOUTHERN DISTRICT OF TEXAS,
DALLAS OR HOUSTON DIVISION, (c) IRREVOCABLY WAIVES ANY CLAIMS THAT ANY
LITIGATION BROUGHT IN ANY OF THE AFOREMENTIONED COURTS HAS BEEN BROUGHT IN AN
INCONVENIENT FORUM, (d) IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF
ANY OF THOSE COURTS IN ANY LITIGATION BY THE MAILING OF COPIES THEREOF BY
CERTIFIED MAIL, RETURN RECEIPT REQUESTED, POSTAGE PREPAID, BY HAND-DELIVERY, OR
BY DELIVERY BY A NATIONALLY RECOGNIZED COURIER SERVICE, AND SERVICE SHALL BE
DEEMED COMPLETE UPON DELIVERY OF THE LEGAL PROCESS AT ITS ADDRESS SET FORTH IN
THIS AGREEMENT, (e) IRREVOCABLY AGREES THAT ANY LEGAL PROCEEDING AGAINST ANY
PARTY TO ANY LOAN DOCUMENT ARISING OUT OF OR IN CONNECTION WITH THE LOAN
DOCUMENTS OR THE OBLIGATION MAY BE BROUGHT IN ONE OF THE AFOREMENTIONED COURTS,
AND (f) IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW, ITS
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR
ARISING OUT 

                                       49
<PAGE>
 
OF ANY LOAN DOCUMENT. The scope of each of the foregoing waivers is intended to
be all-encompassing of any and all disputes that may be filed in any court and
that relate to the subject matter of this transaction, including contract
claims, tort claims, breach of duty claims, and all other common law and
statutory claims. Borrower (for itself and on behalf of each of its Consolidated
Affiliates) acknowledges that these waivers are a material inducement to each
Agent's and each Lender's agreement to enter into a business relationship, that
each Agent and each Lender has already relied on these waivers in entering into
this Agreement, and that each Agent and each Lender will continue to rely on
each of these waivers in related future dealings. Borrower (for itself and on
behalf of each of its Consolidated Affiliates) further warrants and represents
that it has reviewed these waivers with its legal counsel, and that it knowingly
and voluntarily agrees to each waiver following consultation with legal counsel.
THE WAIVERS IN THIS SECTION 13.8 ARE IRREVOCABLE, MEANING THAT THEY MAY NOT BE
MODIFIED EITHER ORALLY OR IN WRITING, AND THESE WAIVERS SHALL APPLY TO ANY
SUBSEQUENT AMENDMENTS, SUPPLEMENTS, OR REPLACEMENTS TO OR OF THIS OR ANY OTHER
LOAN DOCUMENT. In the event of Litigation, this Agreement may be filed as a
written consent to a trial by the court.

     13.9     AMENDMENTS, CONSENTS, CONFLICTS, AND WAIVERS.

     (A)      Any provision of the Loan Documents may be amended or waived if,
but only if, such amendment or waiver is in writing and is signed by Borrower
and Administrative Agent; provided that no such amendment or waiver shall be
effective, without the consent of the Required Lenders as provided in the
Intercreditor Agreement furnished to Borrower.

     (B)       Any conflict or ambiguity between the terms and provisions of
this Agreement and terms and provisions in any other Loan Document is controlled
by the terms and provisions of this Agreement to the extent (and only to the
extent) of such conflict.

     (C)       No course of dealing or any failure or delay by any Agent, any
Lender, or any of their respective Representatives with respect to exercising
any Right of any Agent or any Lender under this Agreement operates as a waiver
thereof. A waiver must be in writing and signed by Administrative Agent and
Lenders to be effective, and a waiver will be effective only in the specific
instance and for the specific purpose for which it is given.

     13.10    MULTIPLE COUNTERPARTS. Any Loan Document may be executed in a
number of identical counterparts, each of which shall be deemed an original for
all purposes and all of which constitute, collectively, one agreement; but, in
making proof of thereof, it shall not be necessary to produce or account for
more than one counterpart. Each Lender need not execute the same counterpart of
this Agreement so long as identical counterparts are executed by Borrower, each
Lender, and each Agent. This Agreement shall become effective when counterparts
of this Agreement have been executed and delivered to Administrative Agent by
each Lender, each Agent, and Borrower, or, in the case only of Lenders, when
Administrative Agent has received telecopied, telexed or other evidence
satisfactory to it that each Lender has executed and is delivering to
Administrative Agent a counterpart of this Agreement.

     13.11     SUCCESSORS AND ASSIGNS; PARTICIPATIONS.

     (A)       Each Loan Document binds and inures to the benefit of the parties
thereto, any intended beneficiary thereof, and each of their respective
successors and permitted assigns. No Lender may, without the prior written
consent of Administrative Agent and, so long as no Default has occurred and is
continuing, Borrower, transfer, pledge, assign, sell any participation in, or
otherwise encumber its portion of the Obligation, except as specifically
permitted by this SECTION 13.11.

     (B)       Subject to the provisions of this section and in accordance with
applicable Law, any Lender having a Commitment equal to or greater than
$25,000,000, or if the Total Commitments have been terminated, then Notes having
outstanding Principal Debt equal to or greater than $25,000,000, may, in the
ordinary course of its commercial banking business, at any time sell to one or
more Persons (each a "PARTICIPANT") participating interests in its portion of
the Obligation; provided that (i) each such participation is not less than
$10,000,000, (ii) except in the case of participations of Competitive Borrowings
or to any of such Lender's Affiliates, Administrative Agent and, so long as no
Default has occurred and is continuing, Borrower have consented to such
participation, such consents not to be unreasonably withheld, and (iii) after
giving effect to such participation, the Lender granting such participation
shall retain a Commitment of at least $15,000,000, or if the Total Commitments
have been terminated, then Notes having outstanding Principal Debt of at least
$15,000,000. The selling Lender shall remain a "Lender" under this Agreement
(and the Participant shall not constitute a "Lender" under this Agreement) and
its obligations under this Agreement shall remain unchanged. The selling Lender
shall remain solely responsible for the performance of its obligations under the
Loan Documents and shall remain the holder of its share of the Principal Debt
for all purposes under this Agreement. Borrower and Administrative Agent shall
continue to deal solely and directly with the selling Lender in connection with
such Lender's Rights and obligations under the Loan Documents. Participants have
no Rights under the Loan Documents, other than certain voting Rights as provided
below. Subject to the following, each Lender may obtain (on behalf of its
Participants) the benefits of SECTION 3 with respect to all participations in
its part of the Obligation outstanding from time to time so long as Borrower is
not obligated to pay any amount in excess of the amount that would be due to
such Lender under SECTION 3 calculated as though no participations have been
made. No Lender may sell any participating interest under which the Participant
has any Rights to approve any amendment, modification or waiver of any Loan
Document, except to the extent the amendment, modification or waiver extends the
due date for payment of any principal, interest or fees due under the Loan
Documents, reduces the interest rate or the amount of principal or fees
applicable to the Obligation (except reductions contemplated by this Agreement),
or releases any guaranty or collateral, if any, for the Obligation. However, if
a Participant is entitled to the benefits of SECTION 3 or a Lender grants Rights
to its Participants to approve amendments to or waivers of the Loan Documents
respecting the matters described in the previous sentence, then such Lender must
include a voting mechanism in the relevant participation agreement whereby a
majority of its portion of the Obligation (whether held by it or participated)
shall control the vote for all of such Lender's portion of the Obligation.

     (C)       Subject to the provisions of this section, any Lender may at any
time, in the ordinary course of its commercial banking business, (i) without the
consent of Borrower or Administrative Agent, assign all or any part of its
Rights and obligations under the Loan Documents to any of its Affiliates so long
as such Affiliate is an Eligible Institution (each a "PURCHASER") and (ii) upon
the prior written consent of Administrative Agent, and so long as no Default has
occurred and is continuing, Borrower, such consents not to be unreasonably
withheld, assign to any other Eligible Institution (each of which is also a
"PURCHASER") a proportionate part (not less than $15,000,000 and an integral
multiple of $1,000,000) of all or any part of its Rights and obligations under
the Loan Documents; provided that (x) each such assignment shall exclude
Competitive Borrowings, unless the assigning Lender is selling all of its Rights
and obligations under the Loan Documents, and (y) after giving effect to such
assignment, unless the assigning Lender is assigning all of its Rights and
Commitments hereunder, the Lender granting such assignment shall retain a
Commitment of at least $15,000,000, or if the Total Commitments have been
terminated, then Notes having outstanding Principal Debt of at least
$15,000,000. Notwithstanding the foregoing, each Agent shall, at all times prior
to its resignation or replacement as an Agent hereunder, retain a minimum
Commitment of $25,000,000, or if the Total Commitments have been terminated,
then Notes having outstanding Principal Debt of at least $25,000,000. In each
case, the Purchaser shall assume those Rights and obligations under an
assignment agreement substantially in the form of EXHIBIT D. Upon (i) delivery
of an executed copy of the assignment agreement to Borrower and Administrative
Agent and (ii) payment of a fee of $3,000 from the transferor to 

                                       51
<PAGE>
 
Administrative Agent, from and after the assignment's effective date (which
shall be after the date of delivery), the Purchaser shall for all purposes be a
Lender party to this Agreement and shall have all the Rights and obligations of
a Lender under this Agreement to the same extent as if it were an original party
to this Agreement with commitments as set forth in the assignment agreement, and
the transferor Lender shall be released from its obligations under this
Agreement to a corresponding extent, and, except as provided in the following
sentence, no further consent or action by Borrower, Lenders, or any Agent shall
be required. Upon the consummation of any transfer to a Purchaser under this
CLAUSE (C), the then-existing SCHEDULE 1 shall automatically be deemed to
reflect the name, address, and Commitment of such Purchaser, Administrative
Agent shall deliver to Borrower and Lenders an amended SCHEDULE 1 reflecting
those changes, Borrower shall execute and deliver to each of the transferor
Lender and the Purchaser a Revolving Credit Note in the face amount of its
respective Commitment following transfer, and, upon receipt of its new Revolving
Credit Note, the transferor Lender shall return to Borrower the Revolving Credit
Note previously delivered to it under this Agreement. A Purchaser is subject to
all the provisions in this SECTION as if it were a Lender signatory to this
Agreement as of the date of this Agreement.

     (D)       Any Lender may at any time, without the consent of Borrower or
Administrative Agent, assign all or any part of its Rights under the Loan
Documents to a Federal Reserve Bank without releasing the transferor Lender from
its obligations thereunder.

     (E)       Notwithstanding any contrary provision in this Agreement, a
Lender may not sell or participate any of its interests for a purchase price
that, directly or indirectly, reflects a discount from face value, without first
offering the sale or participation to the other Lenders on a Pro Rata basis
(which must be accepted or rejected within five (5) Business Days after the
offer).

      13.12    DISCHARGE ONLY UPON PAYMENT IN FULL; REINSTATEMENT IN CERTAIN
CIRCUMSTANCES. Borrower's obligations under the Loan Documents remain in full
force and effect until the Total Commitment is terminated and the Obligation is
paid in full (except for provisions under the Loan Documents which by their
terms expressly survive payment of the Obligation and termination of the Loan
Documents). If at any time any payment of the principal of or interest on any
Note or any other amount payable by Borrower or any other obligor on the
Obligation under any Loan Document is rescinded or must be restored or returned
upon the insolvency, bankruptcy or reorganization of Borrower or otherwise, the
obligations of Borrower under the Loan Documents with respect to that payment
shall be reinstated as though the payment had been due but not made at that
time.

      13.13    CONFIDENTIALITY. Each Lender agrees to hold any confidential
information which (a) it has received prior to the Closing Date from Borrower
which is confidential and is not otherwise publicly available, and (b) it may
receive from Borrower pursuant to this Agreement after the Closing Date which
Borrower has marked "confidential" and is not otherwise publicly available, in
confidence, except (i) to other Lenders, (ii) to legal counsel, accountants, and
other professional advisors to such Lender who agree to be bound by the terms of
this Section, (iii) to regulatory officials, but only to the extent required by
such officials, (iv) upon prior notice to Borrower (which Lenders agree shall be
delivered as promptly as practicable), in connection with or response to
compliance with any Law or at the request of any Tribunal, but only to the
extent required by such Law or Tribunal, (v) upon prior notice to Borrower
(which Lenders agree shall be delivered as promptly as practicable), in
connection with any legal proceedings to which such Lender is a party, but only
to the extent required by such proceedings, and (vi) to prospective Participants
or Purchasers who agree to be bound by the terms of this Section.

      13.14    ARBITRATION. ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE
PARTIES HERETO INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF OR RELATING TO

DAYS OF THE DEMAND FOR ARBITRATION; FURTHER, THE ARBITRATOR SHALL ONLY, UPON A
SHOWING OF CAUSE, BE PERMITTED TO EXTEND THE COMMENCEMENT OF SUCH HEARING FOR UP

WAIVER BY LENDERS OF THE PROTECTION AFFORDED TO IT BY 12 U.S.C. (S) 91 OR ANY
SUBSTANTIALLY EQUIVALENT STATE LAW; OR (iii) LIMIT THE RIGHT OF LENDERS OR
AGENTS HERETO (A) TO EXERCISE SELF HELP REMEDIES SUCH AS (BUT NOT LIMITED TO)

MORTGAGE MAY BE ACCOMPLISHED BY ANY OF THE FOLLOWING: THE EXERCISE OF A POWER OF
SALE UNDER THE DEED OF TRUST OR MORTGAGE, OR BY JUDICIAL SALE UNDER THE DEED OF
TRUST OR MORTGAGE, OR BY JUDICIAL FORECLOSURE. NEITHER THIS EXERCISE OF SELF
HELP REMEDIES NOR THE INSTITUTION OR MAINTENANCE OF AN ACTION FOR FORECLOSURE OR

PARTY, INCLUDING THE CLAIMANT IN ANY SUCH ACTION TO ARBITRATE THE MERITS OF THE
CONTROVERSY OR CLAIM OCCASIONING RESORT TO SUCH REMEDIES.

      13.15    LIMITATION OF LIABILITY OF TRUSTEES, SHAREHOLDERS AND OFFICERS OF

                             REVOLVING CREDIT NOTE

$________                        Dallas, Texas             As of August 11, 1998


     1.   FOR VALUE RECEIVED, PROLOGIS TRUST, a Maryland real estate investment
trust (formerly known as Security Capital Industrial Trust) ("MAKER"), hereby
unconditionally promises to pay to the order of ________________ ("PAYEE"), at
the address of Administrative Agent (defined below) set forth in the Credit
Agreement defined below, the sum of ______ Dollars ($____) (or, if less, so much
thereof as may be advanced), in lawful money of the United States of America.
Capitalized terms not defined herein shall have the meaning assigned to those
terms in the Credit Agreement defined below.

     2.   The unpaid principal amount of, and accrued unpaid interest on, this
Note is payable in accordance with the Credit Agreement (as defined in SECTION 5
below).

     3.   The unpaid principal balance advanced and outstanding hereunder shall
bear interest from the date of advance until maturity at the rate per annum
provided in the Credit Agreement that is selected by Maker pursuant to the
Credit Agreement.  The interest rate specified in this section is subject to
adjustment under the circumstances described in the Credit Agreement.  Interest
shall be computed in the manner provided in the Credit Agreement.

     4.   Notwithstanding any provision contained in this Note or any other
document executed or delivered in connection with this Note or in connection
with the Credit Agreement, Payee shall never be deemed to have contracted for or
be entitled to receive, collect or apply as interest on this Note, any amount in
excess of the maximum rate of interest permitted to be charged by applicable
law, and, if Payee ever receives, collects or applies as interest any such
excess, then the amount that would be excessive interest shall be applied to
reduce the unpaid principal balance of this Note, and, if the principal balance
of this Note is paid in full by that application, then any remaining excess
shall promptly be paid to Maker.  In determining whether the interest paid or
payable under any specific contingency exceeds the highest lawful rate, Maker
and Payee shall, to the maximum extent permitted under applicable law, (a)
characterize any non-principal payment (other than payments expressly designated
as interest payments hereunder) as an expense or fee rather than as interest,
(b) exclude voluntary prepayments and the effect thereof, and (c) spread the
total amount of interest throughout the entire contemplated term of this Note so
that the interest rate is uniform throughout that term.

     5.   This Note has been executed and delivered pursuant to an Amended and
Restated Credit Agreement (as amended, modified or restated from time to time,
the "CREDIT AGREEMENT") dated as of August 11, 1998, executed by and between
Maker, NationsBank, N.A., as Administrative Agent ("ADMINISTRATIVE AGENT"), the
Documentation Agent defined therein, the Syndication Agent defined therein, and
the Lenders defined therein, and is one of the "Revolving Credit Notes" referred
to therein, and the holder of this Note is entitled to the benefits provided in
the Credit Agreement.  Reference is hereby made to the Credit Agreement for a
statement of (a) the obligation of Payee to advance funds hereunder, (b) the
prepayment rights and obligations of Maker, and (c) the events upon which the
maturity of this Note may be accelerated.

$_________                        Dallas, Texas            As of August 11, 1998


     1.   FOR VALUE RECEIVED, PROLOGIS TRUST, a Maryland real estate investment
trust (formerly known as Security Capital Industrial Trust) ("MAKER"), hereby
unconditionally promises to pay to the order of       ___________ ("PAYEE"), at
the address of Administrative Agent (defined below) set forth in the Credit
Agreement defined below:

     (A) On the last day of the Interest Period for any Competitive Borrowing
dispersed by Lender to Borrower, which Interest Period ends prior to the
Termination Date, the aggregate principal amount of such Competitive Borrowing
outstanding and unpaid on such last day of such Interest Period; and

     (B) On the Termination Date, the aggregate principal amount of all
Competitive Borrowings disbursed by Lender to Borrower and outstanding and
unpaid on the Termination Date.

     2.   The unpaid principal balance advanced and outstanding hereunder shall
bear interest from the date of advance until maturity at the rate per annum
provided in the Credit Agreement that is selected by Maker pursuant to the
Credit Agreement.  The interest rate specified in this section is subject to
adjustment under the circumstances described in the Credit Agreement.  Interest
shall be computed in the manner provided in the Credit Agreement.

     3.   Notwithstanding any provision contained in this Note or any other
document executed or delivered in connection with this Note or in connection
with the Credit Agreement, Payee shall never be deemed to have contracted for or
be entitled to receive, collect or apply as interest on this Note, any amount in
excess of the maximum rate of interest permitted to be charged by applicable
law, and, if Payee ever receives, collects or applies as interest any such
excess, then the amount that would be excessive interest shall be applied to
reduce the unpaid principal balance of this Note, and, if the principal balance
of this Note is paid in full by that application, then any remaining excess
shall promptly be paid to Maker. In determining whether the interest paid or
payable under any specific contingency exceeds the highest lawful rate, Maker
and Payee shall, to the maximum extent permitted under applicable law, (a)
characterize any non-principal payment (other than payments expressly designated
as interest payments hereunder) as an expense or fee rather than as interest,
(b) exclude voluntary prepayments and the effect thereof, and (c) spread the
total amount of interest throughout the entire contemplated term of this Note so
that the interest rate is uniform throughout that term.

     4.   This Note has been executed and delivered pursuant to an Amended and
Restated Credit Agreement (as amended, modified or restated from time to time,
the "CREDIT AGREEMENT") dated as of August 11, 1998, executed by and between
Maker, NationsBank, N.A., as Administrative Agent ("ADMINISTRATIVE AGENT"), the
Documentation Agent defined therein, the Syndication Agent defined therein, and
the Lenders defined therein, and is one of the "Competitive Bid Notes" referred
to therein, and the holder of this Note is entitled to the benefits provided in
the Credit Agreement.  Reference is hereby made to the Credit Agreement for a
statement of (a) the prepayment rights and obligations of Maker, and (b) the
events upon which the maturity of this Note may be accelerated.

     5.   If the principal of, or any installment of interest on, this Note
becomes due and payable on a day other than a Business Day, then the maturity
thereof shall be extended to the next succeeding Business Day. If this Note, or
any installment or payment due hereunder, is not paid when due, whether at
maturity or by acceleration, or if it is collected through a bankruptcy, probate
or other court, whether before or after maturity, then Maker shall pay all costs
of collection, including, but not limited to, attorney's fees incurred by the
holder of this Note.  All past due principal of, and to the extent permitted by
applicable law, interest on this Note shall bear interest until paid at the rate
provided in the Credit Agreement.

     6.   Maker and all sureties, endorsers, guarantors, and other parties ever
liable for payment of any sums payable pursuant to the terms of this Note,
jointly and severally waive demand, presentment for payment, protest, notice of
protest, notice of acceleration, notice of intent to accelerate, diligence in
collection, the bringing of any suit against any party, and any notice of or
defense on account of any extensions, renewals, partial payments, or changes in
any manner of or in this Note or in any of its terms, provisions, and covenants,
or any releases or substitutions of any security, or any delay, indulgence, or
other act of any trustee or any holder hereof, whether before or after maturity.

performed in the State of Texas.  Except to the extent that the laws of the

                                SWING LINE NOTE


$50,000,000                       Dallas, Texas            As of August 11, 1998


     1.   FOR VALUE RECEIVED, PROLOGIS TRUST, a Maryland real estate investment
trust (formerly known as Security Capital Industrial Trust) ("MAKER"), hereby
unconditionally promises to pay to the order of NATIONSBANK, N.A. ("PAYEE"), at
the address of Administrative Agent (defined below) set forth in the Credit
Agreement defined below, the sum of FIFTY MILLION AND 00/100 DOLLARS
($50,000,000) (or, if less, so much thereof as may be advanced), in lawful money
of the United States of America.  Capitalized terms not defined herein shall
have the meaning assigned to those terms in the Credit Agreement defined below.

     2.   The unpaid principal amount of, and accrued unpaid interest on, this
Note is payable in accordance with the Credit Agreement (defined in SECTION 5
below).

     3.   The unpaid principal balance advanced and outstanding hereunder shall
bear interest from the date of advance until maturity at the rate per annum
provided in the Credit Agreement that is selected by Maker pursuant to the
Credit Agreement.  The interest rate specified in this section is subject to
adjustment under the circumstances described in the Credit Agreement.  Interest
shall be computed in the manner provided in the Credit Agreement.

     4.   Notwithstanding any provision contained in this Note or any other
document executed or delivered in connection with this Note or in connection
with the Credit Agreement, Payee shall never be deemed to have contracted for or
be entitled to receive, collect or apply as interest on this Note, any amount in
excess of the maximum rate of interest permitted to be charged by applicable
law, and, if Payee ever receives, collects or applies as interest any such
excess, then the amount that would be excessive interest shall be applied to
reduce the unpaid principal balance of this Note, and, if the principal balance
of this Note is paid in full by that application, then any remaining excess
shall promptly be paid to Maker. In determining whether the interest paid or
payable under any specific contingency exceeds the highest lawful rate, Maker
and Payee shall, to the maximum extent permitted under applicable law, (a)
characterize any non-principal payment (other than payments expressly designated
as interest payments hereunder) as an expense or fee rather than as interest,
(b) exclude voluntary prepayments and the effect thereof, and (c) spread the
total amount of interest throughout the entire contemplated term of this Note so
that the interest rate is uniform throughout that term.

     5.   This Note has been executed and delivered pursuant to an Amended and
Restated Credit Agreement (as amended, modified or restated from time to time,
the "CREDIT AGREEMENT") dated as of August 11, 1998, executed by and between
Maker, NationsBank, N.A., as Administrative Agent ("ADMINISTRATIVE AGENT"),
Payee, the Documentation Agent defined therein, the Syndication Agent defined
therein, and the Lenders defined therein, and is the "Swing Line Note" referred
to therein, and the holder of this Note is entitled to the benefits provided in
the Credit Agreement.  Reference is hereby made to the Credit Agreement for a
statement of (a) the obligation of Payee to advance funds hereunder, (b) the
prepayment rights and obligations of Maker, and (c) the events upon which the
maturity of this Note may be accelerated.

                                    Page 42
<PAGE>
 
     6.   If the principal of, or any installment of interest on, this Note
becomes due and payable on a day other than a Business Day, then the maturity
thereof shall be extended to the next succeeding Business Day. If this Note, or
any installment or payment due hereunder, is not paid when due, whether at
maturity or by acceleration, or if it is collected through a bankruptcy, probate
or other court, whether before or after maturity, then Maker shall pay all costs
of collection, including, but not limited to, attorney's fees incurred by the
holder of this Note.  All past due principal of, and to the extent permitted by
applicable law, interest on this Note shall bear interest until paid at the rate
provided in the Credit Agreement.

     7.   Maker and all sureties, endorsers, guarantors, and other parties ever
liable for payment of any sums payable pursuant to the terms of this Note,
jointly and severally waive demand, presentment for payment, protest, notice of
protest, notice of acceleration, notice of intent to accelerate, diligence in
collection, the bringing of any suit against any party, and any notice of or
defense on account of any extensions, renewals, partial payments, or changes in
any manner of or in this Note or in any of its terms, provisions, and covenants,
or any releases or substitutions of any security, or any delay, indulgence or
other act of any trustee or any holder hereof, whether before or after maturity.

     8.   This Note is being executed and delivered, and is intended to be
performed in the State of Texas.  Except to the extent that the laws of the
United States may apply to the terms hereof, the substantive laws of the State
of Texas shall govern the validity, construction, enforcement, and
interpretation of this Note.

creating the Guaranteed Debt) or otherwise.  Without limiting the foregoing or
Guarantors' liability hereunder, to the extent that any Credit Party advances
funds or extends credit to Borrower, and does not receive payments or benefits
thereon in the amounts and at the times required or provided by applicable
agreements or laws, Guarantors are absolutely liable to make such payments to
(and confer such benefits on) such Credit Party, on a timely basis.

     1.3  GUARANTY OF OBLIGATION.  Subject to the limitations set forth in
SECTION 1.10, Guarantors hereby irrevocably and unconditionally guarantee,
jointly and severally, to the Credit Parties (a) the due and punctual payment of
the Guaranteed Debt, and (b) the timely performance of all other obligations now
or hereafter owed by Borrower to the Credit Parties under the Credit Agreement.
Each Guarantor hereby irrevocably and unconditionally covenants and agrees that
it is liable for the Guaranteed Debt as primary obligor.

     1.4  NATURE OF GUARANTY.  This Guaranty Agreement is intended to be an
irrevocable, absolute, continuing guaranty of payment and is not a guaranty of
collection.  This Guaranty Agreement may not be revoked by any Guarantor;
provided, however, if, according to applicable law, it shall ever be determined
or held that a guarantor under a continuing guaranty such as this Guaranty
Agreement shall have the absolute right, notwithstanding the express agreement
of such a guarantor otherwise, to revoke such guaranty as to Guaranteed Debt
which has then not yet arisen, then any Guarantor may deliver to Agent written
notice, in addition to giving such notice as provided in SECTION 5.2 hereof,
that such Guarantor will not be liable hereunder for any Guaranteed Debt
created, incurred, or arising after the giving of such notice, and such notice
will be effective as to such Guarantor from and after (but not before) such
times as said written notice is actually delivered to, in addition to giving
such notice as provided in SECTION 5.2 hereof, and received by and receipted for
in writing by Administrative Agent; provided that such notice shall not in
anywise affect, impair, or limit the liability and responsibility of any other
person or entity with respect to any Guaranteed Debt theretofore existing or
thereafter existing, arising, renewed, extended, or modified; provided, further,
that such notice shall not affect, impair, or release the liability and
responsibility of any such Guarantor with respect to Guaranteed Debt created,
incurred, or arising (or in respect of any Guaranteed Debt agreed or
contemplated, in any respect, to be created, whether advanced or not and whether
committed to by the Credit Parties or not, including, without limitation, any
discretionary advances or extensions of credit which may be made by any Credit
Party at its option in the future under any type of loan or credit agreement,
arrangement or undertaking) prior to the receipt of such notice by
Administrative Agent as aforesaid, or in respect of any renewals, 

                                    Page 46
<PAGE>
 
extensions, or modifications of such Guaranteed Debt, or in respect of interest
or costs of collection thereafter accruing on or with respect to such Guaranteed
Debt, or with respect to attorneys' fees thereafter becoming payable hereunder
with respect to such Guaranteed Debt, and shall continue to be effective with
respect to any Guaranteed Debt arising or created after any attempted revocation
by any Guarantor. The fact that at any time or from time to time the Guaranteed
Debt may be increased, reduced, or paid in full shall not release, discharge, or
reduce the obligation of Guarantors with respect to indebtedness or obligations
of Borrower to the Credit Parties thereafter incurred (or other Guaranteed Debt
thereafter arising) under the Credit Agreement, the Notes, or otherwise. This
Guaranty Agreement may be enforced by the Credit Parties and any subsequent
holder of the Guaranteed Debt and shall not be discharged by the assignment or
negotiation of all or part of the Guaranteed Debt.

     1.5  PAYMENT BY GUARANTORS.  If all or any part of the Guaranteed Debt
shall not be punctually paid when due, whether at maturity or earlier by
acceleration or otherwise, then Guarantors shall, immediately upon demand by
Administrative Agent, and without presentment, protest, notice of protest,
notice of nonpayment, notice of intention to accelerate or acceleration, or any
other notice whatsoever, pay in lawful money of the United States of America,
the amount due on the Guaranteed Debt to Administrative Agent, for the benefit
of the Credit Parties, at Administrative Agent's principal office in Dallas,
Texas.  Such demand(s) may be made at any time coincident with or after the time
for payment of all or part of the Guaranteed Debt, and may be made from time to
time with respect to the same or different items of Guaranteed Debt.  Such
demand shall be deemed made, given, and received in accordance with SECTION 5.2
hereof.

     1.6  PAYMENT OF EXPENSES.  In the event that any Guarantor should breach or
fail to timely perform any provisions of this Guaranty Agreement, then
Guarantors shall, immediately upon demand by Administrative Agent, pay to
Administrative Agent, for the benefit of the Credit Parties, all costs and
expenses (including court costs and reasonable attorneys' fees) incurred by the
Credit Parties in the enforcement hereof or the preservation of the Credit
Parties' rights hereunder.  The covenant contained in this SECTION 1.6 shall
survive the payment of the Guaranteed Debt.

     1.7  NO DUTY TO PURSUE OTHERS.  It shall not be necessary for any Credit
Party (and Guarantors hereby waive any rights which Guarantors may have to
require any Credit Party), in order to enforce payment by any Guarantor, first
to (a) institute suit or exhaust its remedies against Borrower or others liable
on the Guaranteed Debt or any other person, (b) enforce the Credit Parties'
rights against any security which shall ever have been given to secure the
Guaranteed Debt, (c) enforce the Credit Parties's rights against any other
Guarantor or any other guarantors of the Guaranteed Debt, (d) join Borrower, any
other Guarantor, or any others liable on the Guaranteed Debt in any action
seeking to enforce this Guaranty Agreement, (e) exhaust any remedies available
to the Credit Parties against any security which shall ever have been given to
secure the Guaranteed Debt, or (e) resort to any other means of obtaining
payment of the Guaranteed Debt.  The Credit Parties shall not be required to
mitigate damages or take any other action to reduce, collect, or enforce the
Guaranteed Debt.  Further, each Guarantor expressly waives each and every right
to which it may be entitled by virtue of the suretyship law of the State of
Texas, including without limitation, any rights pursuant to Rule 31, Texas Rules
of Civil Procedure, Articles 1986 and 1987, Revised Civil Statutes of Texas and
Chapter 34 of the Texas Business and Commerce Code.

     1.8  WAIVER OF NOTICES, ETC.  Each Guarantor agrees to the provisions of
the Credit Agreement, the Notes, and the other Loan Documents, and hereby waives
notice of (a) any loans or advances made by any Credit Party to Borrower, (b)
acceptance of this Guaranty Agreement, (c) any amendment or extension of the
Credit Agreement, the Notes, the other Loan Documents, or any other instrument
or document pertaining to 

                                    Page 47
<PAGE>
 
all or any part of the Guaranteed Debt, (d) the execution and delivery by
Borrower and any Credit Party of any other loan or credit agreement or of
Borrower's execution and delivery of any promissory notes or other documents in
connection therewith, (e) the occurrence of any Potential Default or Event of
Default, (f) any Credit Party's transfer or disposition of the Guaranteed Debt,
or any part thereof, (g) sale or foreclosure (or posting or advertising for sale
or foreclosure) of any collateral for the Guaranteed Debt, (h) protest, proof of
nonpayment, or default by Borrower, (i) the release of any other Guarantor, or
(j) any other action at any time taken or omitted by any Credit Party, and,
generally, all demands and notices of every kind in connection with this
Guaranty Agreement, the Credit Agreement, the Notes, the other Loan Documents,
and any documents or agreements evidencing, securing, or relating to any of the
Guaranteed Debt and the obligations hereby guaranteed.

     1.9  EFFECT OF BANKRUPTCY, OTHER MATTERS.  In the event that, pursuant to
any insolvency, bankruptcy, reorganization, receivership, or other debtor relief
law, or any judgment, order, or decision thereunder, or for any other reason,
(a) any Credit Party must rescind or restore any payment, or any part thereof,
received by such Credit Party in satisfaction of the Guaranteed Debt, as set
forth herein, any prior release or discharge from the terms of this Guaranty
Agreement given to any Guarantor by such Credit Party shall be without effect,
and this Guaranty Agreement shall remain in full force and effect, (b) Borrower
shall cease to be liable to the Credit Parties for any of the Guaranteed Debt
(other than by reason of the indefeasible payment in full thereof by Borrower),
then the obligations of each Guarantor under this Guaranty Agreement shall
remain in full force and effect.  It is the intention of the Credit Parties and
Guarantors that Guarantors' obligations hereunder shall not be discharged except
by Guarantors' performance of such obligations and then only to the extent of
such performance.  Without limiting the generality of the foregoing, it is the
intention of the Credit Parties and Guarantors that the filing of any bankruptcy
or similar proceeding by or against Borrower or any other person or party
obligated on any portion of the Guaranteed Debt shall not affect the obligations
of Guarantors under this Guaranty Agreement or the rights of the Credit Parties
under this Guaranty Agreement, including, without limitation, the right or
ability of the Credit Parties to pursue or institute suit against Guarantors for
the entire Guaranteed Debt.

     1.10 LIMITATION.  It is the intention of Guarantors and the Credit Parties
that the amount of the Guaranteed Debt shall be in, but not in excess of, the
maximum amount permitted by fraudulent conveyance, fraudulent transfer, or other
similar laws applicable to Guarantors.  Accordingly, notwithstanding anything to
the contrary contained in this Guaranty Agreement or any other agreement or
instrument executed in connection with the payment of any of the Guaranteed
Debt, the amount of the Guaranteed Debt shall be limited to that amount which
after giving effect thereto would not (a) render Guarantor insolvent, (b) result
in the fair saleable value of the assets of any Guarantor being less than the
amount required to pay its debts and other liabilities (including contingent
liabilities) as they mature, or (c) leave any Guarantor with unreasonably small
capital to carry out its business as now conducted and as proposed to be
conducted, including its capital needs, as such concepts described in (A), (B),
and (C) herein are determined under applicable law, if the obligations of any
such Guarantor hereunder would otherwise be set aside, terminated, annulled, or
avoided for such reason by a court of competent jurisdiction in a proceeding
actually pending before such court.

interest, or lien contemplated or intended to be given, created, or granted as
security for the repayment of the Guaranteed Debt shall not be properly

that Guarantors are not entering into this Guaranty Agreement in reliance on, or
in contemplation of the benefits of, the validity, enforceability,
collectibility, or value of any of the collateral for the Guaranteed Debt;
notwithstanding the foregoing, Guarantors do not hereby waive or release
(expressly or impliedly) any right to be subrogated to the rights of the Credit

unambiguous and unequivocal intention of Guarantors that Guarantors shall be
obligated to pay the Guaranteed Debt when due, notwithstanding any occurrence,
circumstance, event, action, or omission whatsoever, whether contemplated or
uncontemplated, and whether or not otherwise or particularly described herein,

                        REPRESENTATIONS AND WARRANTIES

     To induce the Credit Parties to enter into the Credit Agreement and extend
credit to Borrower, each Guarantor represents and warrants to the Credit Parties
that:

     3.1  BENEFIT.  Each Guarantor has received, or will receive, direct or
indirect benefit from the making of this Guaranty and the Guaranteed Debt;

     3.2  FAMILIARITY AND RELIANCE.  Each Guarantor is familiar with, and has
independently reviewed books and records regarding, the financial condition of
Borrower and is familiar with the value of any and all collateral intended to be
created as security for the payment of the Guaranteed Debt; however, no
Guarantor is relying on such financial condition or the collateral as an
inducement to enter into this Guaranty Agreement;

     3.3  NO REPRESENTATION BY THE CREDIT PARTIES.  No Credit Party or any other
party has made any representation, warranty, or statement to any Guarantor in
order to induce any Guarantor to execute this Guaranty Agreement;

     3.4  GUARANTOR'S FINANCIAL CONDITION.  As of the date hereof, and after
giving effect to this Guaranty Agreement and the contingent obligation evidenced
hereby, each Guarantor is, and will be, Solvent;

     3.5  DIRECTORS' DETERMINATION OF BENEFIT.  The Board of Directors,
partners, members, or other managers and owners of each Guarantor have, acting
pursuant to a duly called and constituted meeting, after proper notice, or
pursuant to a valid unanimous consent, has determined that this Guaranty
directly or indirectly benefits such Guarantor and is in the best interests of
such Guarantor;

     3.6  LEGALITY.  The execution, delivery, and performance by each Guarantor
of this Guaranty Agreement and the consummation of the transactions contemplated
hereunder (a) have been duly authorized by all necessary trust action of each
Guarantor, and (b) do not, and will not, contravene or conflict with any law,
statute, or regulation whatsoever to which any Guarantor is subject or
constitute a default (or an event which with notice or lapse of time or both
would constitute a default) under, or result in the breach of, any indenture,
mortgage, deed of trust, charge, lien, or any contract, agreement, or other
instrument to which any Guarantor is a party or which may be applicable to any
Guarantor or any of its assets, or violate any provisions of its Constituent
Documents; this Guaranty Agreement is a legal and binding obligation of each
Guarantor and is enforceable in accordance with its terms, except as limited by
bankruptcy, insolvency or other laws of general application relating to the
enforcement of creditors' rights; and

                                    Page 51
<PAGE>
 
     3.7  SURVIVAL.  All representations and warranties made by each Guarantor
herein shall survive the execution hereof.

                                   SECTION 4

                     SUBORDINATION OF CERTAIN INDEBTEDNESS

     4.1  SUBORDINATION OF GUARANTOR CLAIMS.  As used herein, the term
"GUARANTOR CLAIMS" shall mean all debts and liabilities of Borrower to any
Guarantor, whether such debts and liabilities now exist or are hereafter
incurred or arise, or whether the obligations of Borrower thereon be direct,
contingent, primary, secondary, several, joint and several, or otherwise, and
irrespective of whether such debts or liabilities be evidenced by note,
contract, open account, or otherwise, and irrespective of the person or persons
in whose favor such debts or liabilities may, at their inception, have been, or
may hereafter be created, or the manner in which they have been or may hereafter
be acquired by any Guarantor.  The Guarantor Claims shall include without
limitation all rights and claims of each Guarantor against Borrower (arising as
a result of subrogation or otherwise) as a result of any Guarantor's payment of
all or a portion of the Guaranteed Debt.  Until the Guaranteed Debt shall be
paid and satisfied in full and each Guarantor shall have performed all of its
obligations hereunder, if a Potential Default or Event of Default exists, then
Guarantors shall not receive or collect, directly or indirectly, from Borrower
or any other party any amount upon the Guarantor Claims.

     4.2  CLAIMS IN BANKRUPTCY.  In the event of receivership, bankruptcy,
reorganization, arrangement, debtor's relief, or other insolvency proceedings
involving Borrower as debtor, the Credit Parties shall have the right to prove
its claim in any such proceeding so as to establish its rights hereunder and
receive directly from the receiver, trustee, or other court custodian dividends
and payments which would otherwise be payable upon Guarantor Claims.  Each
Guarantor hereby assigns such dividends and payments to the Credit Parties.
Should any Credit Party receive, for application upon the Guaranteed Debt, any
such dividend or payment which is otherwise payable to any Guarantor, and which,
as between Borrower and such Guarantor, shall constitute a credit upon the
Guarantor Claims, then upon payment to the Credit Parties in full of the
Guaranteed Debt, such Guarantor shall become subrogated to the rights of the
Credit Parties to the extent that such payments to the Credit Parties on the
Guarantor Claims have contributed toward the liquidation of the Guaranteed Debt,
and such subrogation shall be with respect to that proportion of the Guaranteed
Debt which would have been unpaid if the Credit Parties had not received
dividends or payments upon the Guarantor Claims.

     4.3  PAYMENTS HELD IN TRUST.  In the event that, notwithstanding SECTIONS
4.1 and 4.2 above, any Guarantor should receive any funds, payment, claim or
distribution which is prohibited by such Sections, such Guarantor agrees to hold
in trust for the Credit Parties, in kind, all funds, payments, claims, or
distributions so received, and agrees that he shall have absolutely no dominion
over such funds, payments, claims, or distributions so received except to pay
them promptly to Administrative Agent, for the benefit of the Credit Parties,
and such Guarantor covenants promptly to pay the same to Administrative Agent,
for the benefit of the Credit Parties.

     4.4  LIENS SUBORDINATE.  Each Guarantor agrees that any liens, security
interests, judgment liens, charges, or other encumbrances upon Borrower's assets
securing payment of the Guarantor Claims shall be and remain inferior and
subordinate to any liens, security interests, judgment liens, charges, or other
encumbrances upon Borrower's assets securing payment of the Guaranteed Debt,
regardless of whether such encumbrances in favor of such Guarantor or the Credit
Parties presently exist or are hereafter created or attach.  

                                    Page 52
<PAGE>
 
Without the prior written consent of Administrative Agent, no Guarantor shall
(a) exercise or enforce any creditor's right it may have against Borrower, or
(b) foreclose, repossess, sequester, or otherwise take steps or institute any
action or proceedings (judicial or otherwise, including, without limitation, the
commencement of, or joinder in, any liquidation, bankruptcy, rearrangement,
debtor's relief, or insolvency proceeding) to enforce any liens, mortgages,
deeds of trust, security interest, collateral rights, judgments, or other
encumbrances on assets of Borrower held by any Guarantor.

     4.5  NOTATION OF RECORDS.  All promissory notes, accounts receivable
ledgers, or other evidences of the Guarantor Claims accepted by or held by each
Guarantor shall contain a specific written notice thereon that the indebtedness
evidenced thereby is subordinated under the terms of this Guaranty Agreement.

                                   SECTION 5

                                 MISCELLANEOUS

     5.1  WAIVER.  No failure to exercise, and no delay in exercising, on the
part of any Credit Party, any right hereunder shall operate as a waiver thereof,
nor shall any single or partial exercise thereof preclude any other or further
exercise thereof or the exercise of any other right.  The rights of the Credit
Parties hereunder shall be in addition to all other rights provided by law.  No
modification or waiver of any provision of this Guaranty Agreement, nor consent
to departure therefrom, shall be effective unless in writing and no such consent
or waiver shall extend beyond the particular case and purpose involved. No
notice or demand given in any case shall constitute a waiver of the right to
take other action in the same, similar, or other instances without such notice
or demand.

     5.2  NOTICES.  Any notices or other communications required or permitted to
be given by this Guaranty Agreement must be (a) given in writing and personally

held to be illegal, invalid, or unenforceable under present or future laws
effective during the term of this Guaranty Agreement, such provision shall be
fully severable and this Guaranty Agreement shall be construed and enforced as
if such illegal, invalid, or unenforceable provision had never comprised a part
of this Guaranty Agreement, and the remaining provisions of this Guaranty
Agreement shall remain in full force and effect and shall not be affected by the
illegal, invalid, or unenforceable provision or by its severance from this
Guaranty Agreement, unless such continued effectiveness of this Guaranty
Agreement, as modified, would be contrary to the basic understandings and
intentions of the parties as expressed herein.

of any other Guarantor hereunder, or by any election by Administrative Agent not
to cause any Consolidated Affiliates of Borrower to become an Additional
Guarantor hereunder.  This Guaranty Agreement shall be fully effective as to any
Guarantor that is or becomes a party hereto regardless of whether any such
person becomes or fails to become or ceases to be a Guarantor hereunder.

                           BORROWER PLEDGE AGREEMENT

     THIS BORROWER PLEDGE AGREEMENT (this "AGREEMENT") is dated as of August 11,
1998, and entered into by and between PROLOGIS TRUST (formerly known as SECURITY
CAPITAL INDUSTRIAL TRUST), a Maryland real estate investment trust ("PLEDGOR"),

agent for and representative of (in such capacity herein called "SECURED PARTY")
the Documentation Agent defined in the Credit Agreement defined below, the
Syndication Agent defined in the Credit Agreement defined below, and the Lenders
defined in the Credit Agreement defined below (collectively, the "CREDIT
PARTIES").

                                R E C I T A L S
                                - - - - - - - -

     1.   Reference is made to that certain Amended and Restated Credit
Agreement dated as of August 11, 1998, by and between Pledgor, Secured Party, as
Administrative Agent, the Documentation Agent defined therein, the Syndication
Agent defined therein, and the Lenders defined therein (as renewed, extended,
amended, or restated, the "CREDIT AGREEMENT"), pursuant to which Lenders have
made certain Commitments, subject to the terms and conditions set forth in the
Credit Agreement, to make loans to Pledgor.

     2.   Capitalized terms used herein shall, unless otherwise indicated, have
the respective meanings set forth in the Credit Agreement.

     3.   Pledgor is the legal and beneficial owner of the intercompany
indebtedness (collectively the "PLEDGED DEBT") described in PART A of SCHEDULE 1
attached hereto and issued by the corporations named therein and issued by the
obligors named therein.

     4.   To secure the Obligation, Pledgor will grant a security interest in,
among other things, the Pledged Debt pursuant to this agreement.

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Pledgor hereby agrees with Secured
Party, for the benefit of the Credit Parties, as follows:

     1.   PLEDGE OF SECURITY.  Pledgor hereby pledges and assigns to Secured
          ------------------                                                
Party, for the ratable benefit of the Credit Parties, and hereby grants to
Secured Party, for the ratable benefit of the Credit Parties, a security
interest in, all of Pledgor's right, title, and interest in and to the following
(the "COLLATERAL"):

     (A)  the Pledged Debt and the instruments evidencing the Pledged Debt, and
all interest, cash, instruments, and other property or proceeds from time to
time received, receivable, or otherwise distributed in respect of or in exchange
for any or all of the Pledged Debt;

     (B)  all additional indebtedness from time to time owed to Pledgor by any
obligor on the Pledged Debt (which indebtedness shall be deemed to be part of
the Pledged Debt) and the instruments evidencing such indebtedness, and all
interest, cash, instruments, and other property or proceeds from time to time
received, receivable, or otherwise distributed in respect of or in exchange for
any or all of such indebtedness;

                                    Page 58
<PAGE>
 
     (C)  all indebtedness from time to time owed to Pledgor by any Person that,
after the date of this Agreement, becomes, as a result of any occurrence, any
Unconsolidated Affiliate of Pledgor (which indebtedness shall be deemed to be
part of the Pledged Debt) if the indebtedness of such Person to Pledgor equals
or exceeds $5,000,000 individually or in the aggregate, and all interest, cash,
instruments, and other property or proceeds from time to time received,
receivable, or otherwise distributed in respect of or in exchange for any or all
of such indebtedness;

     (D)  to the extent not included in any other paragraph of this SECTION 1,
all other general intangibles (including without limitation, tax refunds and
rights to demand issuance of a certificate evidencing the Collateral), arising
out of or in connection with rights to payment or performance, choses in action,
and judgments taken on any rights or claims included in the Collateral;

     (E)  all of Pledgor's right, title, and interest in and to all books,
records, ledger cards, files, correspondence, computer programs, tapes, disks,
and related data processing software that at any time evidence or contain
information relating to any of the Collateral or are otherwise necessary or
helpful in the collection thereof or realization thereupon; and

     (F)  to the extent not covered by CLAUSES (A) through (E) above, all
proceeds of any or all of the foregoing Collateral.  For purposes of this
Agreement, the term "PROCEEDS" includes whatever is receivable or received when
Collateral or proceeds are sold, exchanged, collected, or otherwise disposed of,
whether such disposition is voluntary or involuntary, and includes, without
limitation, proceeds of any indemnity or guaranty payable to Pledgor or Secured
Party from time to time with respect to any of the Collateral.

     2.   SECURITY FOR OBLIGATIONS.  This Agreement secures, and the Collateral
          ------------------------                                             
is collateral security for, the prompt payment or performance in full when due,
whether at stated maturity, by required prepayment, declaration, acceleration,
demand, or otherwise (including the payment of amounts that would become due but
for the operation of the automatic stay under Section 362(a) of the Bankruptcy
Code, 11 U.S.C. (S) 362(a)), of all obligations and liabilities of every nature
of Pledgor now or hereafter existing under or arising out of or in connection
with the Credit Agreement and the other Loan Documents and all renewals or
extensions thereof, whether for principal, interest (including without
limitation interest that, but for the filing of a petition in bankruptcy with
respect to Pledgor, would accrue on such obligations), fees, expenses,
indemnities, or otherwise, whether voluntary or involuntary, direct or indirect,
absolute or contingent, liquidated or unliquidated, whether or not jointly owed
with others, and whether or not from time to time decreased or extinguished and
later increased, created, or incurred, and all or any portion of such
obligations or liabilities that are paid, to the extent all or any part of such
payment is avoided or recovered directly or indirectly from Secured Party or any
Lender as a preference, fraudulent transfer, or otherwise (all such obligations
and liabilities being the "UNDERLYING DEBT"), and all obligations of every
nature of Pledgor now or hereafter existing under this Agreement (all such
obligations of Pledgor, together with the Underlying Debt, being the "SECURED
OBLIGATIONS").

     3.   DELIVERY OF COLLATERAL; RELEASE OF COLLATERAL.
          --------------------------------------------- 

     (A)  All certificates or instruments representing or evidencing the
Collateral shall be delivered to and held by or on behalf of Secured Party
pursuant hereto and shall be in suitable form for transfer by delivery or, as
applicable, shall be accompanied by Pledgor's endorsement, where necessary, or
duly executed instruments of transfer or assignment in blank, all in form and
substance satisfactory to Secured Party.  Secured Party shall have the right, at
any time in its discretion and without notice to Pledgor, to transfer to or 

                                    Page 59
<PAGE>
 
to register in the name of Secured Party or any of its nominees any or all of
the Collateral, subject only to the revocable rights specified in Section 6(a).
In addition, Secured Party shall have the right at any time to exchange
certificates or instruments representing or evidencing Collateral for
certificates or instruments of smaller or larger denominations.

     (B)  If the indebtedness of any obligor with respect to the Pledged Debt or
any other indebtedness pledged hereunder is less than $5,000,000 individually or
in the aggregate, then, upon the request of Pledgor so long as no Event of
Default exists, Secured Party shall release such Collateral and all certificates
or instruments representing or evidencing such Collateral shall be delivered to
Pledgor.

     4.   REPRESENTATIONS AND WARRANTIES.  Pledgor represents and warrants as
          ------------------------------

     (A)  DUE AUTHORIZATION, ETC. OF COLLATERAL.  All of the Pledged Debt has
          -------------------------------------                              
been duly authorized, authenticated or issued, and delivered and is the legal,

offering and sale of securities generally).

     (E)  PERFECTION.  The pledge of the Collateral pursuant to this Agreement
          ----------

         ---------------------                                                  
upon their issuance, any and all instruments or other evidences of additional

Person to Pledgor equals or exceeds $5,000,000 individually or in the aggregate.

     (C) PLEDGE AMENDMENTS.  Pledgor shall, upon obtaining any additional
         -----------------

Party a Pledge and Security Amendment, duly executed by Pledgor, in
substantially the form of EXHIBIT A attached hereto (a "PLEDGE AND SECURITY

this Agreement.  Pledgor hereby authorizes Secured Party to attach each Pledge
and Security Amendment to this Agreement and agrees that all Pledged Debt listed
on any Pledge and Security Amendment delivered to Secured Party shall for all
purposes hereunder be considered Collateral; provided that the failure of
Pledgor to execute a Pledge and Security Amendment with respect to any
additional Pledged Debt pledged pursuant to this Agreement shall not impair the
security interest of Secured Party therein or otherwise adversely affect the
rights and remedies of Secured Party hereunder with respect thereto.

     (D) LOSS OR DEPRECIATION OF COLLATERAL.  Pledgor shall promptly notify
         ----------------------------------                                
Secured Party of any event of which such becomes aware causing material loss or
depreciation in the value of any portion of the Collateral.

     (E) WRITTEN NOTICES.  Pledgor shall promptly deliver to Secured Party all
         ---------------                                                      
written notices received by it with respect to the Collateral.

     (F) TAXES AND ASSESSMENTS.  Pledgor shall pay promptly when due all taxes,
         ---------------------                                                 
assessments, and governmental charges or levies imposed upon, and all claims
against, the Collateral, except to the extent the validity thereof is being
contested in good faith and by appropriate proceedings and in which reserves or
other appropriate provisions, if any, as shall be required in conformity with
GAAP, have been made or provided therefor; provided that Pledgor shall in any
event pay such taxes, assessments, charges, levies, or claims not later than
five (5) days prior to the date of any proposed sale under any judgement, writ,
or warrant of attachment entered or filed against Pledgor or any of the
Collateral as a result of the failure to make such payment.

     (G) FURTHER ASSURANCES; PERFECTION.  Pledgor shall from time to time, at
         ------------------------------                                      
the expense of Pledgor, promptly execute and deliver all further instruments and
documents, and take all further action, that may be necessary or desirable, or
that Secured Party may reasonably request, in order to perfect and protect any
security interest granted or purported to be granted hereby or to enable Secured
Party to exercise and enforce its rights and remedies hereunder with respect to
any Collateral.  Without limiting the generality of the foregoing, Pledgor will:

         (I)   at the request of Secured Party, mark conspicuously each item of
     its records pertaining to the Collateral with a legend in form and
     substance satisfactory to Secured Party, indicating that such Collateral is
     subject to the security interest granted hereby;

                                    Page 61
<PAGE>
 
          (II)   execute and file such financing or continuation statements, or
     amendments thereto, and such other instruments or notices, as may be
     necessary or desirable, or as Secured Party may reasonably request, in
     order to perfect and preserve the security interests granted or purported
     to be granted hereby; and

          (III)  at Secured Party's request, appear in and defend any action or
     proceeding that may affect Pledgor's title to or Secured Party's security
     interest in all or any part of the Collateral.

     (H)  AUTHORIZATION TO FILE FINANCING STATEMENTS.
          ------------------------------------------ 

          (I)    Pledgor hereby authorizes Secured Party to file one or more
     financing or continuation statements, and amendments thereto, relative to
     all or any part of the Collateral, in such filing offices as Secured Party
     shall deem appropriate, and Pledgor shall execute and deliver to Secured
     Party such financing or continuation statements, and amendments thereto,
     promptly upon the request of Secured Party and shall pay Secured Party's
     reasonable costs and expenses incurred in connection therewith.

          (II)   Pledgor hereby further authorizes Secured Party to file one or
     more financing or continuation statements, and amendments thereto, relative
     to all or any part of the Collateral without the signature of Pledgor, and
     Pledgor agrees that a carbon, photographic, or other reproduction of this
     Agreement or of a financing statement signed by Pledgor shall be sufficient
     as a financing statement and may be filed as a financing statement in any
     and all jurisdictions.

     6.   RIGHT TO RECEIVE PAYMENTS.
          --------------------------

     (A)  So long as no Event of Default shall have occurred and be continuing:

          (I)    Pledgor shall be entitled to receive and retain, and to utilize
     free and clear of the lien of this Agreement, any and all interest paid in
     respect of the Collateral; provided, however, that any and all interest
     paid or payable other than in cash in respect of, and instruments and other
     property received, receivable, or otherwise distributed in respect of, or
     in exchange for, any Collateral shall be, and shall forthwith be delivered
     to Secured Party to hold as, Collateral and shall, if received by Pledgor,
     be received in trust for the benefit of Secured Party, be segregated from
     the other property or funds of Pledgor and be forthwith delivered to
     Secured Party as Collateral in the same form as so received (with all
     necessary endorsements); and

          (II)   Secured Party shall promptly execute and deliver (or cause to
     be executed and delivered) to Pledgor all such instruments as Pledgor may
     from time to time reasonably request for the purpose of enabling Pledgor to
     receive the principal or interest payments which it is authorized to
     receive and retain pursuant to PARAGRAPH (I) above.

     (B)  Upon the occurrence and during the continuation of an Event of
     Default:

          (I)    all rights of Pledgor to receive the interest payments which it
     would otherwise be authorized to receive and retain pursuant to SECTION
     6(A)(I) shall cease, and all such rights shall thereupon become vested in
     Secured Party who shall thereupon have the sole right to receive and hold
     as Collateral such interest payments; and

                                    Page 62
<PAGE>
 
          (II)   all principal and interest payments which are received by
     Pledgor contrary to the provisions of this SECTION 6(B)(I) shall be
     received in trust for the benefit of Secured Party, shall be segregated
     from other funds of Pledgor and shall forthwith be paid over to Secured
     Party as Collateral in the same form as so received (with any necessary
     endorsements).

     (C)  Notwithstanding any of the foregoing, Pledgor agrees that this
Agreement shall not in any way be deemed to obligate Secured Party or any Lender
to assume any of Pledgor's obligations, duties, expenses, or liabilities arising
out of this Agreement (including, without limitation, Pledgor's obligations as
the holder of the Pledged Debt) or under any and all other agreements now
existing or hereafter drafted or executed (collectively, the "PLEDGOR
OBLIGATIONS") unless Secured Party or Lender otherwise expressly agrees to
assume any or all of said Pledgor Obligations in writing.  Without limiting the
generality of the foregoing, neither the grant of the security interest in the
Collateral in favor of Secured Party as provided herein nor the exercise by
Secured Party of any of its rights hereunder nor any action by Secured Party in
connection with a foreclosure on the Collateral shall be deemed to constitute
Secured Party as a partner of any partnership or a member of any limited
liability company; provided, however, that in the event Secured Party or any
Lender elects to become a substituted partner of any partnership or a member of
any limited liability company in place of Pledgor, Secured Party or such Lender,
as the case may be, shall be entitled to and shall become such a substitute
partner or member.

     7.   SECURED PARTY APPOINTED ATTORNEY-IN-FACT.  Pledgor hereby irrevocably
          ----------------------------------------                             
appoints Secured Party as Pledgor's attorney-in-fact, with full authority in the
place and stead of Pledgor and in the name of Pledgor, Secured Party or
otherwise, from time to time in Secured Party's discretion to take any action
and to execute any instrument that Secured Party may deem necessary or advisable
to accomplish the purposes of this Agreement, including without limitation:

     (A)  to file one or more financing or continuation statements, or
amendments thereto, relative to all or any part of the Collateral without the
signature of Pledgor;

     (B)  subsequent to an Event of Default, to ask, demand, collect, sue for,
recover, compound, receive, and give acquittance and receipts for moneys due and
to become due under or in respect of any of the Collateral;

     (C)  subsequent to an Event of Default, to receive, endorse, and collect
any instruments made payable to Pledgor representing any principal, or interest
payment, or other distribution in respect of the Collateral or any part thereof
and to give full discharge for the same; and

     (D)  subsequent to an Event of Default, to file any claims or take any
action or institute any proceedings that Secured Party may deem necessary or
desirable for the collection of any of the Collateral or otherwise to enforce
the rights of Secured Party with respect to any of the Collateral.

     8.   SECURED PARTY MAY PERFORM.  If Pledgor fails to perform any agreement
          -------------------------                                            
contained herein, then Secured Party may itself perform, or cause performance
of, such agreement, and the expenses of Secured Party incurred in connection
therewith shall be payable by Pledgor under SECTION 12(B).

     9.   STANDARD OF CARE.  The powers conferred on Secured Party hereunder are
          ----------------                                                      
solely to protect its interest in the Collateral and shall not impose any duty
upon it to exercise any such powers.  Except for the exercise of reasonable care
in the custody of any Collateral in its possession and the accounting for moneys

                                    Page 63
<PAGE>
 
actually received by it hereunder, Secured Party shall have no duty as to any
Collateral, it being understood that Secured Party shall have no responsibility
for (a) ascertaining or taking action with respect to calls, conversions,
exchanges, maturities, tenders, or other matters relating to any Collateral,
whether or not Secured Party has or is deemed to have knowledge of such matters,
(b) taking any necessary steps (other than steps taken in accordance with the
standard of care set forth above to maintain possession of the Collateral) to
preserve rights against any parties with respect to any Collateral, (c) taking
any necessary steps to collect or realize upon the Secured Obligations or any
guarantee therefor, or any part thereof, or any of the Collateral, or (d)
initiating any action to protect the Collateral against the possibility of a
decline in market value. Secured Party shall be deemed to have exercised
reasonable care in the custody and preservation of Collateral in its possession
if such Collateral is accorded treatment substantially equal to that which
Secured Party accords its own property consisting of negotiable securities.

     10.  REMEDIES.  If any Event of Default shall have occurred and be
          --------                                                     
continuing, then Secured Party may exercise in respect of the Collateral, in
addition to all other rights and remedies provided for herein or otherwise
available to it, all the rights and remedies of a secured party on default under
the Uniform Commercial Code as adopted in the State of Texas (the "CODE")
(whether or not the Code applies to the affected Collateral), and Secured Party
may also in its sole discretion, without notice except as specified below, sell
the Collateral or any part thereof in one or more parcels at public or private
sale, at any exchange or broker's board or at any of Secured Party's offices or
elsewhere, for cash, on credit, or for future delivery, at such time or times
and at such price or prices and upon such other terms as Secured Party may deem
commercially reasonable, irrespective of the impact of any such sales on the
market price of the Collateral.  Secured Party or any Lender may be the
purchaser of any or all of the Collateral at any such sale and Secured Party, as
agent for and representative of Lenders (but not any Lender or Lenders in its or
their respective individual capacities unless Requisite Lenders shall otherwise
agree in writing), shall be entitled, for the purpose of bidding and making
settlement or payment of the purchase price for all or any portion of the
Collateral sold at any such public sale, to use and apply any of the Secured
Obligations as a credit on account of the purchase price for any Collateral
payable by Secured Party at such sale.  Each purchaser at any such sale shall
hold the property sold absolutely free from any claim or right on the part of
Pledgor, and Pledgor hereby waives (to the extent permitted by applicable law)
all rights of redemption, stay, and/or appraisal which it now has or may at any
time in the future have under any rule of law or statute now existing or
hereafter enacted.  Pledgor agrees that, to the extent notice of sale shall be
required by law, at least ten (10) days' notice to Pledgor of the time and place
of any public sale or the time after which any private sale is to be made shall
constitute reasonable notification.  Secured Party shall not be obligated to
make any sale of Collateral regardless of notice of sale having been given.
Secured Party may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned.
Pledgor hereby waives any claims against Secured Party arising by reason of the
fact that the price at which any Collateral may have been sold at such a private
sale was less than the price which might have been obtained at a public sale,
even if Secured Party accepts the first offer received and does not offer such
Collateral to more than one offeree.  If the proceeds of any sale or other
disposition of the Collateral are insufficient to pay all the Secured
Obligations, then Pledgor shall be liable for the deficiency and the fees of any
attorneys employed by Secured Party to collect such deficiency.

     11.  APPLICATION OF PROCEEDS.  Except as expressly provided elsewhere in
          -----------------------                                            
this Agreement, all proceeds received by Secured Party in respect of any sale
of, collection from, or other realization upon all or any part of the Collateral
may, in the discretion of Secured Party, be held by Secured Party as Collateral
for, and/or then, or at any time thereafter, applied in full or in part by
Secured Party against, the Secured Obligations in the following order of
priority:

                                    Page 64
<PAGE>
 
          FIRST:  To the payment of all costs and expenses of such sale,
     collection, or other realization, including reasonable compensation to
     Secured Party and its agents and counsel, and all other expenses,
     liabilities, and advances made or incurred by Secured Party in connection
     therewith, and all amounts for which Secured Party is entitled to
     indemnification hereunder and all advances made by Secured Party hereunder
     for the account of Pledgor, and to the payment of all costs and expenses
     paid or incurred by Secured Party in connection with the exercise of any
     right or remedy hereunder, all in accordance with SECTION 12;

          SECOND:  To the payment of all other Secured Obligations (for the
     ratable benefit of the Credit Parties); and

          THIRD:  To the payment to or upon the order of Pledgor, or to
     whosoever may be lawfully entitled to receive the same or as a court of
     competent jurisdiction may direct, of any surplus then remaining from such
     proceeds.

     12.  INDEMNITY AND EXPENSES.
          ---------------------- 

     (A)  Pledgor agrees to indemnify each Credit Party from and against any and
all claims, losses, and liabilities in any way relating to, growing out of, or
resulting from this Agreement and the transactions contemplated hereby
(including, without limitation, enforcement of this Agreement), except to the
extent such claims, losses, or liabilities result solely from Secured Party's or
such Lender's gross negligence or willful misconduct as finally determined by a
court of competent jurisdiction.

     (B)  Pledgor shall pay to Secured Party upon demand the amount of any and
all costs and expenses, including the reasonable fees and expenses of its
counsel and of any experts and agents, that Secured Party may incur in
connection with (i) the administration of this Agreement, (ii) the custody or
preservation of, or the sale of, collection from, or other realization upon, any
of the Collateral, (iii) the exercise or enforcement of any of the rights of
Secured Party hereunder, or (iv) the failure by Pledgor to perform or observe
any of the provisions hereof.

     13.  CONTINUING SECURITY INTEREST; TRANSFER OF LOANS.  This Agreement shall
          -----------------------------------------------                       
create a continuing security interest in the Collateral and shall (a) remain in
full force and effect until the payment in full of all Secured Obligations and
the cancellation or termination of the Commitments, (b) be binding upon Pledgor,
its successors and assigns, and (c) inure, together with the rights and remedies
of Secured Party hereunder, to the benefit of Secured Party and its successors,
transferees, and assigns.  Without limiting the generality of the foregoing
CLAUSE (C), but subject to the provisions of SECTION 13.11 of the Credit
Agreement, any Lender may assign or otherwise transfer any of its Rights and
obligations to any other Person, and such other Person shall thereupon become
vested with all the benefits in respect thereof granted to Lenders herein or
otherwise.  Upon the indefeasible payment in full of all Secured Obligations and
the cancellation or termination of the Commitments, the security interest
granted hereby shall terminate and all rights to the Collateral shall revert to
Pledgor.  Upon any such termination Secured Party will, at Pledgor's expense,
execute and deliver to Pledgor such documents as Pledgor shall reasonably
request to evidence such termination and Pledgor shall be entitled to the
return, upon its request and at its expense, against receipt and without
recourse to Secured Party, of such of the Collateral as shall not have been sold
or otherwise applied pursuant to the terms hereof.

     14.  SECURED PARTY AS AGENT.
          ---------------------- 

     (A)  Secured Party has been appointed to act as Secured Party hereunder by
Lenders.  Secured Party shall be obligated, and shall have the right hereunder,
to make demands, to give notices, to exercise or refrain from exercising any
rights, and to take or refrain from taking any action (including, without
limitation, the release or substitution of Collateral), solely in accordance
with this Agreement and the Credit Agreement.

     (B)  Secured Party shall at all times be the same Person that is
Administrative Agent under the Credit Agreement.  Written notice of resignation
by Administrative Agent pursuant to the Credit Agreement shall also constitute
notice of resignation as Secured Party under this Agreement; removal of
Administrative Agent pursuant to the Credit Agreement shall also constitute
removal as Secured Party under this Agreement; and appointment of a successor
Administrative Agent pursuant to the Credit Agreement shall also constitute
appointment of a successor Secured Party under this Agreement.  Upon the
acceptance of any appointment as Administrative Agent under SECTION 12.1 of the
Credit Agreement by a successor Administrative Agent, that successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges, and duties of the retiring or removed Secured Party
under this Agreement, and the retiring or removed Secured Party under this
Agreement shall promptly (i) transfer to such successor Secured Party all sums,
securities and other items of Collateral held hereunder, together with all
records and other documents necessary or appropriate in connection with the
performance of the duties of the successor Secured Party under this Agreement,
and (ii) execute and deliver to such successor Secured Party such amendments to
financing statements, and take such other actions, as may be necessary or
appropriate in connection with the assignment to such successor Secured Party of
the security interests created hereunder, whereupon such retiring or removed
Secured Party shall be discharged from its duties and obligations under this
Agreement.  After any retiring or removed Administrative Agent's resignation or
removal hereunder as Secured Party, the provisions of this Agreement shall inure
to its benefit as to any actions taken or omitted to be taken by it under this
Agreement while it was Secured Party hereunder.

     15.  AMENDMENTS; ETC.  No amendment, modification, termination, or waiver
          ----------------                                                    
of any provision of this Agreement, and no consent to any departure by Pledgor
from the terms and conditions hereof, shall in any event be effective unless the
same shall be in writing and signed by Secured Party and, in the case of any
such amendment or modification, by Pledgor.  Any such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
it was given.

     16.  NOTICES.  Any notice or other communication herein required or
          -------

or sent by telecopy or United States mail or courier service to each such party
at its address set forth in the Credit Agreement, on the signature pages hereof
or to such other addresses as each such party may in writing hereafter indicate.
Such notice or other communication shall be deemed to have been given when
delivered in person or by courier service, upon receipt of telecopy or telex, or
three (3) Business Days after depositing it in the United states mail with
postage prepaid and properly addressed; provided that any notice, request, or
demand to or upon Administrative Agent or Lenders shall not be effective until
received.

     17.  FAILURE OR INDULGENCE NOT WAIVER: REMEDIES CUMULATIVE.  No failure or
          -----------------------------------------------------                
delay on the part of Secured Party in the exercise of any power, right, or
privilege hereunder shall impair such power, right, or privilege or be construed
to be a waiver of any default or acquiescence therein, nor shall any single or
partial exercise of any such power, right, or privilege preclude any other or
further exercise thereof or of any other 

                                    Page 66
<PAGE>
 
power, right, or privilege. All rights and remedies existing under this
Agreement are cumulative to, and not exclusive of, any rights or remedies
otherwise available.

     18.  SEVERABILITY.  In case any provision in or obligation under this
          ------------                                                    
Agreement shall be invalid, illegal, or unenforceable in any jurisdiction, the
validity, legality, and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

          --------

acknowledged by Pledgor to be sufficient for personal jurisdiction in any action
against Pledgor in any such court and to be otherwise effective and binding
service in every respect.  Nothing herein shall affect the right to serve

Party to bring proceedings against Pledgor in the courts of any other
jurisdiction.

     22.  WAIVER OF JURY TRIAL. PLEDGOR AND SECURED PARTY HEREBY AGREE TO WAIVE
          --------------------                                                 
THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED
UPON OR ARISING OUT OF THIS AGREEMENT.  The scope of this waiver is intended to
be all-encompassing of any and all disputes that may be filed in any court and
that relate to the subject matter of this transaction, including without

common law and statutory claims.  Pledgor and Secured Party each acknowledge
that this waiver is a material inducement for Pledgor and Secured Party to enter

sufficiency of which are hereby acknowledged, Pledgor hereby agrees with Secured
Party, for the benefit of the Credit Parties, as follows:

     (C)  all indebtedness from time to time owed to Pledgor by any Person that,
after the date of this Agreement, becomes, as a result of any occurrence, any

     2.   SECURITY FOR OBLIGATIONS.  This Agreement secures, and the Collateral
          ------------------------                                             
is collateral security for, the prompt payment or performance in full when due,

Code, 11 U.S.C. (S) 362(a)), of all obligations and liabilities of every nature
of Pledgor now or hereafter existing under or arising out of or in connection
with the Credit Agreement and the other Loan Documents and all renewals or
extensions thereof, whether for principal, interest (including without
limitation interest that, but for the filing of a petition in bankruptcy with
respect to Pledgor, would accrue on such obligations), fees, expenses,
indemnities, or otherwise, whether voluntary or involuntary, direct or indirect,
absolute or contingent, liquidated or unliquidated, whether or not jointly owed
with others, and whether or not from time to time decreased or extinguished and
later increased, created, or incurred, and all or any portion of such
obligations or liabilities that are paid, to the extent all or any part of such
payment is avoided or recovered directly or indirectly from Secured Party or any
Lender as a preference, fraudulent transfer, or otherwise (all such obligations
and liabilities being the "UNDERLYING DEBT"), and all obligations of every
nature of Pledgor now or hereafter existing under this Agreement (all such
obligations of Pledgor, together with the Underlying Debt, being the "SECURED
OBLIGATIONS").

     3.   DELIVERY OF COLLATERAL; RELEASE OF COLLATERAL.
          --------------------------------------------- 

     (A)  All certificates or instruments representing or evidencing the
Collateral shall be delivered to and held by or on behalf of Secured Party

duly executed instruments of transfer or assignment in blank, all in form and
substance satisfactory to Secured Party.

right at any time to exchange certificates or instruments representing or

denominations.

     (B)  If the indebtedness of any obligor with respect to the Pledged Debt or
any other indebtedness pledged hereunder is less than $5,000,000 individually or
in the aggregate, then, upon the request of Pledgor so long as no Event of
Default exists, Secured Party shall release such Collateral and all certificates
or instruments representing or evidencing such Collateral shall be delivered to
Pledgor.

     4.   REPRESENTATIONS AND WARRANTIES.  Pledgor represents and warrants as
          ------------------------------                                     
follows:

     (A)  DUE AUTHORIZATION, ETC. OF COLLATERAL.  All of the Pledged Debt has
          -------------------------------------                              
been duly authorized, authenticated or issued, and delivered and is the legal,
valid, and binding obligation of the issuers thereof, subject to the general

issued and outstanding intercompany indebtedness evidenced by a promissory note
of the respective issuers thereof owing to Pledgor.

     (C)  OWNERSHIP OF COLLATERAL.  Pledgor is the legal, record, and beneficial
          -----------------------

interest created by this Agreement.

     (D)  GOVERNMENTAL AUTHORIZATIONS.  No authorization, approval, or other
          ---------------------------                                       
action by, and no notice to or filing with, any Governmental Authority is
required for either (i) the pledge by Pledgor of the Collateral pursuant to this
Agreement and the grant by Pledgor of the security interest granted hereby, (ii)
the execution, delivery, or performance of this Agreement by Pledgor, or (iii)
the exercise by Secured Party of the voting or other rights, or the remedies in
respect of the Collateral, provided for in this Agreement (except as may be
required in connection with a disposition of Collateral by laws affecting the
offering and sale of securities generally).

     (E)  PERFECTION.  The pledge of the Collateral pursuant to this Agreement
          ----------

supplied to Secured Party by or on behalf of Pledgor with respect to the
Collateral is accurate and complete in all material respects.

     5.   ASSURANCES AND COVENANTS OF PLEDGOR.
          ----------------------------------- 

     (A)  TRANSFERS AND OTHER LIENS.  Pledgor shall not:
          -------------------------                     

          (I) except as expressly permitted by the Credit Agreement, sell,
     assign (by operation of law or otherwise), pledge, or hypothecate or
     otherwise dispose of, or grant any option with respect to, any of the
     Collateral; or

                                    Page 74
<PAGE>
 
          (II)  create or suffer to exist any Lien upon or with respect to any
     of the Collateral, except for Permitted Encumbrances.

     (B)  ADDITIONAL COLLATERAL. Pledgor shall (i) pledge hereunder, immediately
          ---------------------
upon their issuance, any and all instruments or other evidences of additional
indebtedness from time to time owed to Pledgor by any obligor on the Pledged
Debt, and (ii) pledge hereunder, immediately upon their issuance, any and all
instruments or other evidences of indebtedness from time to time owed to Pledgor
by any Person that after the date of this Agreement becomes, as a result of any
occurrence, any Unconsolidated Affiliate of Pledgor if the indebtedness of such
Person to Pledgor equals or exceeds $5,000,000 individually or in the aggregate.

     (C)  PLEDGE AMENDMENTS.  Pledgor shall, upon obtaining any additional
          -----------------                                               
indebtedness required to be pledged hereunder as provided in SECTION 5(B),
promptly (and in any event within five (5) Business Days) deliver to Secured
Party a Pledge and Security Amendment, duly executed by Pledgor, in
substantially the form of EXHIBIT A attached hereto (a "PLEDGE AND SECURITY
AMENDMENT"), in respect of the additional Pledged Debt to be pledged pursuant to
this Agreement.  Pledgor hereby authorizes Secured Party to attach each Pledge
and Security Amendment to this Agreement and agrees that all Pledged Debt listed
on any Pledge and Security Amendment delivered to Secured Party shall for all
purposes hereunder be considered Collateral; provided that the failure of
Pledgor to execute a Pledge and Security Amendment with respect to any
additional Pledged Debt pledged pursuant to this Agreement shall not impair the
security interest of Secured Party therein or otherwise adversely affect the
rights and remedies of Secured Party hereunder with respect thereto.

     (D)  LOSS OR DEPRECIATION OF COLLATERAL.  Pledgor shall promptly notify
          ----------------------------------                                
Secured Party of any event of which such becomes aware causing material loss or
depreciation in the value of any portion of the Collateral.

     (E)  WRITTEN NOTICES.  Pledgor shall promptly deliver to Secured Party all
          ---------------                                                      
written notices received by it with respect to the Collateral.

     (F)  TAXES AND ASSESSMENTS.  Pledgor shall pay promptly when due all taxes,
          ---------------------                                                 
assessments, and governmental charges or levies imposed upon, and all claims
against, the Collateral, except to the extent the validity thereof is being
contested in good faith and by appropriate proceedings and in which reserves or
other appropriate provisions, if any, as shall be required in conformity with
GAAP, have been made or provided therefor; provided that Pledgor shall in any
event pay such taxes, assessments, charges, levies, or claims not later than
five (5) days prior to the date of any proposed sale under any judgement, writ,
or warrant of attachment entered or filed against Pledgor or any of the
Collateral as a result of the failure to make such payment.

     (G)  FURTHER ASSURANCES; PERFECTION.  Pledgor shall from time to time, at
          ------------------------------                                      
the expense of Pledgor, promptly execute and deliver all further instruments and
documents, and take all further action, that may be necessary or desirable, or
that Secured Party may reasonably request, in order to perfect and protect any
security interest granted or purported to be granted hereby or to enable Secured
Party to exercise and enforce its rights and remedies hereunder with respect to
any Collateral.  Without limiting the generality of the foregoing, Pledgor will:

                                    Page 75
<PAGE>
 
          (I)    at the request of Secured Party, mark conspicuously each item
     of its records pertaining to the Collateral with a legend in form and
     substance satisfactory to Secured Party, indicating that such Collateral is
     subject to the security interest granted hereby;

          (II)   execute and file such financing or continuation statements, or
     amendments thereto, and such other instruments or notices, as may be
     necessary or desirable, or as Secured Party may reasonably request, in
     order to perfect and preserve the security interests granted or purported
     to be granted hereby; and

          (III)  at Secured Party's request, appear in and defend any action or
     proceeding that may affect Pledgor's title to or Secured Party's security
     interest in all or any part of the Collateral.

     (H)  AUTHORIZATION TO FILE FINANCING STATEMENTS.
          ------------------------------------------ 

          (I)  Pledgor hereby authorizes Secured Party to file one or more
     financing or continuation statements, and amendments thereto, relative to
     all or any part of the Collateral, in such filing offices as Secured Party
     shall deem appropriate, and Pledgor shall execute and deliver to Secured
     Party such financing or continuation statements, and amendments thereto,
     promptly upon the request of Secured Party and shall pay Secured Party's
     reasonable costs and expenses incurred in connection therewith.

          (II) Pledgor hereby further authorizes Secured Party to file one or
     more financing or continuation statements, and amendments thereto, relative
     to all or any part of the Collateral without the signature of Pledgor, and
     Pledgor agrees that a carbon, photographic, or other reproduction of this
     Agreement or of a financing statement signed by Pledgor shall be sufficient
     as a financing statement and may be filed as a financing statement in any
     and all jurisdictions.

     6.   RIGHT TO RECEIVE PAYMENTS.
          --------------------------

     (A)  So long as no Event of Default shall have occurred and be continuing:

          (I) Pledgor shall be entitled to receive and retain, and to utilize
     free and clear of the lien of this Agreement, any and all interest paid in
     respect of the Collateral; provided, however, that any and all interest
     paid or payable other than in cash in respect of, and instruments and other
     property received, receivable, or otherwise distributed in respect of, or
     in exchange for, any Collateral shall be, and shall forthwith be delivered
     to Secured Party to hold as, Collateral and shall, if received by Pledgor,
     be received in trust for the benefit of Secured Party, be segregated from
     the other property or funds of Pledgor and be forthwith delivered to
     Secured Party as Collateral in the same form as so received (with all
     necessary endorsements); and

          (II) Secured Party shall promptly execute and deliver (or cause to be
     executed and delivered) to Pledgor all such instruments as Pledgor may from
     time to time reasonably request for the purpose of enabling Pledgor to
     receive the principal or interest payments which it is authorized to
     receive and retain pursuant to PARAGRAPH (I) above.

     (B)  Upon the occurrence and during the continuation of an Event of
     Default:

                                    Page 76
<PAGE>
 
          (I)  all rights of Pledgor to receive the interest payments which it
     would otherwise be authorized to receive and retain pursuant to SECTION
     6(A)(I) shall cease, and all such rights shall thereupon become vested in
     Secured Party who shall thereupon have the sole right to receive and hold
     as Collateral such interest payments; and

          (II) all principal and interest payments which are received by Pledgor
     contrary to the provisions of this SECTION 6(B)(I) shall be received in
     trust for the benefit of Secured Party, shall be segregated from other
     funds of Pledgor and shall forthwith be paid over to Secured Party as
     Collateral in the same form as so received (with any necessary
     endorsements).

     (C)  Notwithstanding any of the foregoing, Pledgor agrees that this
Agreement shall not in any way be deemed to obligate Secured Party or any Lender
to assume any of Pledgor's obligations, duties, expenses, or liabilities arising
out of this Agreement (including, without limitation, Pledgor's obligations as
the holder of the Pledged Debt) or under any and all other agreements now
existing or hereafter drafted or executed (collectively, the "PLEDGOR
OBLIGATIONS") unless Secured Party or Lender otherwise expressly agrees to
assume any or all of said Pledgor Obligations in writing.  Without limiting the
generality of the foregoing, neither the grant of the security interest in the
Collateral in favor of Secured Party as provided herein nor the exercise by
Secured Party of any of its rights hereunder nor any action by Secured Party in
connection with a foreclosure on the Collateral shall be deemed to constitute
Secured Party as a partner of any partnership or a member of any limited
liability company; provided, however, that in the event Secured Party or any
Lender elects to become a substituted partner of any partnership or a member of
any limited liability company in place of Pledgor, Secured Party or such Lender,
as the case may be, shall be entitled to and shall become such a substitute
partner or member.

     7.   SECURED PARTY APPOINTED ATTORNEY-IN-FACT.  Pledgor hereby irrevocably
          ----------------------------------------                             
appoints Secured Party as Pledgor's attorney-in-fact, with full authority in the
place and stead of Pledgor and in the name of Pledgor, Secured Party or
otherwise, from time to time in Secured Party's discretion to take any action
and to execute any instrument that Secured Party may deem necessary or advisable
to accomplish the purposes of this Agreement, including without limitation:

     (A)  to file one or more financing or continuation statements, or
amendments thereto, relative to all or any part of the Collateral without the
signature of Pledgor;

     (B)  subsequent to an Event of Default, to ask, demand, collect, sue for,
recover, compound, receive, and give acquittance and receipts for moneys due and
to become due under or in respect of any of the Collateral;

     (C)  subsequent to an Event of Default, to receive, endorse, and collect
any instruments made payable to Pledgor representing any principal, or interest
payment, or other distribution in respect of the Collateral or any part thereof
and to give full discharge for the same; and

     (D)  subsequent to an Event of Default, to file any claims or take any
action or institute any proceedings that Secured Party may deem necessary or
desirable for the collection of any of the Collateral or otherwise to enforce
the rights of Secured Party with respect to any of the Collateral.

                                    Page 77
<PAGE>
 
     8.   SECURED PARTY MAY PERFORM.  If Pledgor fails to perform any agreement
          -------------------------                                            
contained herein, then Secured Party may itself perform, or cause performance
of, such agreement, and the expenses of Secured Party incurred in connection
therewith shall be payable by Pledgor under SECTION 12(B).

     9.   STANDARD OF CARE.  The powers conferred on Secured Party hereunder are
          ----------------                                                      
solely to protect its interest in the Collateral and shall not impose any duty
upon it to exercise any such powers.  Except for the exercise of reasonable care
in the custody of any Collateral in its possession and the accounting for moneys
actually received by it hereunder, Secured Party shall have no duty as to any
Collateral, it being understood that Secured Party shall have no responsibility
for (a) ascertaining or taking action with respect to calls, conversions,
exchanges, maturities, tenders, or other matters relating to any Collateral,
whether or not Secured Party has or is deemed to have knowledge of such matters,
(b) taking any necessary steps (other than steps taken in accordance with the
standard of care set forth above to maintain possession of the Collateral) to
preserve rights against any parties with respect to any Collateral, (c) taking
any necessary steps to collect or realize upon the Secured Obligations or any
guarantee therefor, or any part thereof, or any of the Collateral, or (d)
initiating any action to protect the Collateral against the possibility of a
decline in market value.  Secured Party shall be deemed to have exercised
reasonable care in the custody and preservation of Collateral in its possession
if such Collateral is accorded treatment substantially equal to that which
Secured Party accords its own property consisting of negotiable securities.

     10.  REMEDIES.  If any Event of Default shall have occurred and be
          --------                                                     
continuing, then Secured Party may exercise in respect of the Collateral, in
addition to all other rights and remedies provided for herein or otherwise
available to it, all the rights and remedies of a secured party on default under
the Uniform Commercial Code as adopted in the State of Texas (the "CODE")
(whether or not the Code applies to the affected Collateral), and Secured Party
may also in its sole discretion, without notice except as specified below, sell
the Collateral or any part thereof in one or more parcels at public or private
sale, at any exchange or broker's board or at any of Secured Party's offices or
elsewhere, for cash, on credit, or for future delivery, at such time or times
and at such price or prices and upon such other terms as Secured Party may deem
commercially reasonable, irrespective of the impact of any such sales on the
market price of the Collateral.  Secured Party or any Lender may be the
purchaser of any or all of the Collateral at any such sale and Secured Party, as
agent for and representative of Lenders (but not any Lender or Lenders in its or
their respective individual capacities unless Requisite Lenders shall otherwise
agree in writing), shall be entitled, for the purpose of bidding and making
settlement or payment of the purchase price for all or any portion of the
Collateral sold at any such public sale, to use and apply any of the Secured
Obligations as a credit on account of the purchase price for any Collateral
payable by Secured Party at such sale.  Each purchaser at any such sale shall
hold the property sold absolutely free from any claim or right on the part of
Pledgor, and Pledgor hereby waives (to the extent permitted by applicable law)
all rights of redemption, stay, and/or appraisal which it now has or may at any
time in the future have under any rule of law or statute now existing or
hereafter enacted.  Pledgor agrees that, to the extent notice of sale shall be
required by law, at least ten (10) days' notice to Pledgor of the time and place
of any public sale or the time after which any private sale is to be made shall
constitute reasonable notification.  Secured Party shall not be obligated to
make any sale of Collateral regardless of notice of sale having been given.
Secured Party may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned.
Pledgor hereby waives any claims against Secured Party arising by reason of the
fact that the price at which any Collateral may have been sold at such a private
sale was less than the price which might have been obtained at a public sale,
even if Secured Party accepts the first offer received and does not offer such
Collateral to more than one offeree.  If the proceeds of any sale or other
disposition of the Collateral are insufficient to pay all the Secured
Obligations, then Pledgor shall be liable for the deficiency and the fees of any
attorneys employed by Secured Party to collect such deficiency.

     11.  APPLICATION OF PROCEEDS.  Except as expressly provided elsewhere in
          -----------------------                                            
this Agreement, all proceeds received by Secured Party in respect of any sale
of, collection from, or other realization upon all or any part of the Collateral
may, in the discretion of Secured Party, be held by Secured Party as Collateral
for, and/or then, or at any time thereafter, applied in full or in part by
Secured Party against, the Secured Obligations in the following order of
priority:

          FIRST:  To the payment of all costs and expenses of such sale,
     collection, or other realization, including reasonable compensation to
     Secured Party and its agents and counsel, and all other expenses,
     liabilities, and advances made or incurred by Secured Party in connection
     therewith, and all amounts for which Secured Party is entitled to
     indemnification hereunder and all advances made by Secured Party hereunder
     for the account of Pledgor, and to the payment of all costs and expenses
     paid or incurred by Secured Party in connection with the exercise of any
     right or remedy hereunder, all in accordance with SECTION 12;

          SECOND:  To the payment of all other Secured Obligations (for the
     ratable benefit of the Credit Parties); and

          THIRD:  To the payment to or upon the order of Pledgor, or to
     whosoever may be lawfully entitled to receive the same or as a court of
     competent jurisdiction may direct, of any surplus then remaining from such
     proceeds.

     12.  INDEMNITY AND EXPENSES.
          ---------------------- 

     (A)  Pledgor agrees to indemnify each Credit Party from and against any and
all claims, losses, and liabilities in any way relating to, growing out of, or
resulting from this Agreement and the transactions contemplated hereby
(including, without limitation, enforcement of this Agreement), except to the
extent such claims, losses, or liabilities result solely from Secured Party's or
such Lender's gross negligence or willful misconduct as finally determined by a
court of competent jurisdiction.

     (B)  Pledgor shall pay to Secured Party upon demand the amount of any and
all costs and expenses, including the reasonable fees and expenses of its
counsel and of any experts and agents, that Secured Party may incur in
connection with (i) the administration of this Agreement, (ii) the custody or
preservation of, or the sale of, collection from, or other realization upon, any
of the Collateral, (iii) the exercise or enforcement of any of the rights of
Secured Party hereunder, or (iv) the failure by Pledgor to perform or observe
any of the provisions hereof.

     13.  CONTINUING SECURITY INTEREST; TRANSFER OF LOANS.  This Agreement shall
          -----------------------------------------------                       
create a continuing security interest in the Collateral and shall (a) remain in
full force and effect until the payment in full of all Secured Obligations and
the cancellation or termination of the Commitments, (b) be binding upon Pledgor,
its successors and assigns, and (c) inure, together with the rights and remedies
of Secured Party hereunder, to the benefit of Secured Party and its successors,
transferees, and assigns.  Without limiting the generality of the foregoing
CLAUSE (C), but subject to the provisions of SECTION 13.11 of the Credit
Agreement, any Lender may assign or otherwise transfer any of its Rights and
obligations to any other Person, and such other Person shall thereupon become
vested with all the benefits in respect thereof granted to Lenders herein or
otherwise.  Upon the indefeasible payment in full of all Secured Obligations and
the cancellation or termination of the Commitments, the security interest
granted hereby shall terminate and all rights to the Collateral shall revert 

                                    Page 79

to Pledgor. Upon any such termination Secured Party will, at Pledgor's expense,
execute and deliver to Pledgor such documents as Pledgor shall reasonably
request to evidence such termination and Pledgor shall be entitled to the
return, upon its request and at its expense, against receipt and without
recourse to Secured Party, of such of the Collateral as shall not have been sold
or otherwise applied pursuant to the terms hereof.

     14.  SECURED PARTY AS AGENT.
          ---------------------- 

     (A)  Secured Party has been appointed to act as Secured Party hereunder by
Lenders.  Secured Party shall be obligated, and shall have the right hereunder,
to make demands, to give notices, to exercise or refrain from exercising any
rights, and to take or refrain from taking any action (including, without
limitation, the release or substitution of Collateral), solely in accordance
with this Agreement and the Credit Agreement.

     (B)  Secured Party shall at all times be the same Person that is
Administrative Agent under the Credit Agreement.  Written notice of resignation
by Administrative Agent pursuant to the Credit Agreement shall also constitute
notice of resignation as Secured Party under this Agreement; removal of
Administrative Agent pursuant to the Credit Agreement shall also constitute
removal as Secured Party under this Agreement; and appointment of a successor
Administrative Agent pursuant to the Credit Agreement shall also constitute
appointment of a successor Secured Party under this Agreement.  Upon the
acceptance of any appointment as Administrative Agent under SECTION 12.1 of the
Credit Agreement by a successor Administrative Agent, that successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges, and duties of the retiring or removed Secured Party
under this Agreement, and the retiring or removed Secured Party under this
Agreement shall promptly (i) transfer to such successor Secured Party all sums,
securities and other items of Collateral held hereunder, together with all
records and other documents necessary or appropriate in connection with the
performance of the duties of the successor Secured Party under this Agreement,
and (ii) execute and deliver to such successor Secured Party such amendments to
financing statements, and take such other actions, as may be necessary or
appropriate in connection with the assignment to such successor Secured Party of
the security interests created hereunder, whereupon such retiring or removed
Secured Party shall be discharged from its duties and obligations under this
Agreement.  After any retiring or removed Administrative Agent's resignation or
removal hereunder as Secured Party, the provisions of this Agreement shall inure
to its benefit as to any actions taken or omitted to be taken by it under this
Agreement while it was Secured Party hereunder.

     15.  AMENDMENTS; ETC.  No amendment, modification, termination, or waiver
          ----------------                                                    
of any provision of this Agreement, and no consent to any departure by Pledgor
from the terms and conditions hereof, shall in any event be effective unless the
same shall be in writing and signed by Secured Party and, in the case of any
such amendment or modification, by Pledgor.  Any such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
it was given.

     16.  NOTICES.  Any notice or other communication herein required or
          -------

demand to or upon Administrative Agent or Lenders shall not be effective until

          -----------------------------------------------------                
delay on the part of Secured Party in the exercise of any power, right, or
privilege hereunder shall impair such power, right, or privilege or be construed
to be a waiver of any default or acquiescence therein, nor shall any single or
partial exercise of any such power, right, or privilege preclude any other or
further exercise thereof or of any other power, right, or privilege.  All rights
and remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.
