ITEM 2.        ACQUISITION OF ASSETS

     Prentiss Properties Trust owns a limited partnership interest and a sole
general partnership interest in Prentiss Properties Acquisition Partners, L.P.
(the "Operating Partnership") through a wholly-owned subsidiary, Prentiss
Properties I, Inc., a Delaware corporation.  Prentiss Properties Trust, as
referred to herein, includes the Company, its majority-owned Operating
Partnership and subsidiaries (collectively, the "Company"). On October 22, 1997,
the Company completed the acquisition of 15 Class "A" suburban office buildings
(the "Terramics Properties"), and the rights to acquire land capable of
supporting up to 1.1 million net rentable square feet of development .  The
buildings total 904,207 square feet and are located in suburban markets in
Pennsylvania and New Jersey near Philadelphia, Pennsylvania.

     The Terramics Properties were purchased for an aggregate purchase price,
including estimated closing costs, of approximately $134 million, including
approximately $14 million in assumed debt, $106 million in cash and 530,062
units of limited partnership in the Operating Partnership ("Units") valued at
approximately $14 million.  The cash portion of the purchase price was paid
primarily through borrowings under a $133 million credit facility (the
"Terramics Bridge Loan").

     The Terramics Properties were acquired pursuant to agreements of
contribution and assignment entered into between the Operating Partnership (as
"Purchaser") and various entities controlled by the Terramics Properties
Associates that held ownership interests in the Terramics Properties.  The
related agreements were filed as exhibits to the Company's current report on
Form 8-K dated October 16, 1997.

     The Company determined the purchase price for the Terramics Properties and
the individually insignificant properties listed in Item 5 of this report on
Form 8-K through an evaluation of the following factors: (i) macro-economic
issues that impact the market in which the property is located; (ii) location
and competition in the property's market; (iii) occupancy of and demand for
properties of a similar type in the same market; (iv) the construction quality
and condition of the property; (v) the potential for increased cash flow after
benefiting from the Company's renovations, refurbishment and upgrades; (vi)
existing tenant base; (vii) purchase price relative to replacement costs; and
(viii) the potential to generate revenue growth at or above levels of economic
growth in the property's market.  Other than changes in those factors, the
Company, after reasonable inquiry, is not aware of any material factors relating
to the properties that would cause the historical financial information provided
in Item 7 not to be necessarily indicative of future operating results for the
properties.

ITEM 5.        OTHER EVENTS

     On July 29, 1997, the Company completed the acquisition, from an unrelated
third-party, of a mortgage note collateralized by one Class "A" suburban office
property (the "World Savings Center").  The property totals 271,055 square feet
and is located in Oakland, California.  The Company has negotiated a deed in
lieu of foreclosure transaction, for no consideration, which provides for the
conveyance of the property, currently held by a partnership for which an
affiliated party (Prentiss Properties WSC, Inc.) is the general partner, to be
transferred to the Company in an arms length transaction on or around January 1,
1998.  The World Savings Center note was purchased for a purchase price of
approximately $37.5 million which was funded with proceeds from a short-term
acquisition facility provided by an affiliate of Lehman Brothers Inc.

     On July 31, 1997, the Company completed the acquisition of three Class "A"
suburban office properties (the "Academy Properties").  The properties total
193,961 square feet and are located in Los Angeles, California. The Academy
Properties were purchased for a purchase price of approximately $23.0 million
which was funded primarily from borrowings under the Company's line of credit.

     On September 9, 1997, the Company completed the acquisition of two Class
"A" suburban office properties (the "Research Properties").  The properties
total 286,325 square feet and are located in the metropolitan Washington, D.C.
area. The Research Properties were purchased for a purchase price of
approximately $40.8 million which was funded primarily from borrowings under
Company's line of credit.

                                       2
<PAGE>
 
     On September 15, 1997, the Company completed the acquisition of two Class
"A" suburban office properties (the "Gateway Properties").  The properties total
203,405 square feet and are located in the suburban Baltimore, Maryland area.
The Gateway Properties were purchased for a purchase price of approximately
$22.6 million which was funded primarily from borrowings under the Company's
line of credit.
 
     The acquisitions of the World Savings Center, the Academy Properties, the
Research Properties and the Gateway Properties do not individually constitute
acquisitions of a "significant amount of assets" as defined under Item 2 of Form
8-K or Rule 3-14 of Regulation S-X.  Rather, these acquisitions, when aggregated
with the Selected 1997 Acquisitions whose audited combined statements of revenue
and certain operating expenses were filed previously by the Company in its
Registration Statement of Form S-11, declared effective on April 29, 1997,
constitute a mathematical majority of individually insignificant 1997
acquisitions, for which audited combined statements of revenue and certain
operating expenses are required under Rule 3-14 of Regulation S-X.  Accordingly,
audited combined statements of revenue and certain operating expenses of the
World Savings Center, the Academy Properties, the Research Properties and the
Gateway Properties are filed herewith.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Trustees and Shareholders of
 Prentiss Properties Trust

          We have audited the accompanying combined statement of revenues and
certain operating expenses of the Terramics Properties (the "Terramics
Properties") for the year ended December 31, 1996. The combined statement of
revenues and certain operating expenses is the responsibility of the Terramics
Properties' owners. Our responsibility is to express an opinion on the combined
statement of revenues and certain operating expenses based on our audit.

          We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined statement of revenues and
certain operating expenses is free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the combined statement of revenues and certain operating expenses. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall presentation of the combined
statement of revenues and certain operating expenses. We believe that our audit
provides a reasonable basis for our opinion.

          The accompanying combined statement of revenues and certain operating
expenses was prepared for the purpose of complying with rules and regulations of
the Securities and Exchange Commission, as described in Note 1, and is not
intended to be a complete presentation of the Terramics Properties' revenues and
expenses and may not be comparable to results from proposed future operations of
the Terramics Properties.

          In our opinion, the combined statement of revenues and certain
operating expenses referred to above presents fairly, in all material respects,
the revenues and certain operating expenses described in Note 1 for the year
ended December 31, 1996, in conformity with generally accepted accounting
principles.

                            (DOLLARS IN THOUSANDS)

1.   BASIS OF PRESENTATION

          The combined statement of revenues and certain operating expenses for
the year ended December 31, 1996 relate to the operations of the Terramics
properties (the "Terramics Properties" or the "Properties"), which were
acquired, on October 22, 1997, by the Company from an unaffiliated third-party
for an aggregate purchase price of $134.0 million (including estimated closing
costs). The Terramics Properties consist of 15 Class "A" suburban office
buildings totaling approximately 904,207 net rentable square feet located in
suburban markets in Pennsylvania and New Jersey near Philadelphia, Pennsylvania.

          The accompanying combined statement excludes certain expenses such as
interest, depreciation and amortization and other costs not directly related to
the future operations of these properties that may not be comparable to the
expenses expected to be incurred in the proposed future operations of these
properties. Management is not aware of any material factors relating to these
properties which would cause the reported financial information not to be
necessarily indicative of future operating results.

          The combined statement of revenues and certain operating expenses have
been prepared on the accrual basis of accounting.

    REVENUE AND EXPENSE RECOGNITION

          Rental income is recorded when due from tenants. The effects of
scheduled rent increases and rental concessions, if any, are recognized on a
straight-line basis over the term of the tenant's lease.

    FUTURE RENTAL REVENUES

          The properties are leased to tenants under net operating leases.
Minimum lease payments receivable, excluding tenant reimbursement of expenses,
under noncancellable operating leases in effect as of December 31, 1996, are
approximately as follows:

                                                 $76,814
                                                ======== 
</TABLE>

          Office space in the Terramics Properties is generally leased to
tenants under lease terms which provide for tenants to pay for increases in
operating expenses in excess of specified amounts.

    USE OF ESTIMATES

          The preparation of the combined statement of revenues and certain
operating expenses requires management to make estimates and assumptions that
affect the reported amounts, revenues and certain operating expenses during the
reporting period. Actual results could differ from those estimates.

paid $681,428 in management fees during the year ended December 31, 1996 to the
Terramics Management Company, an affiliate of the entities owning the

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Trustees and Shareholders of
     Prentiss Properties Trust

          We have audited the accompanying combined statements of revenues and
certain operating expenses of the World Savings Center Property for the years
ended December 31, 1996, 1995 and 1994. The statements of revenues and certain
operating expenses are the responsibility of the World Savings Center Property's
owners. Our responsibility is to express an opinion on the combined statements
of revenues and certain operating expenses based on our audit.

          We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined statements of revenues and
certain operating expenses are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the combined statements of revenues and certain operating expenses. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall presentation of the
combined statements of revenues and certain operating expenses. We believe that
our audit provides a reasonable basis for our opinion.

          The accompanying combined statements of revenues and certain operating
expenses were prepared for the purpose of complying with rules and regulations
of the Securities and Exchange Commission, as described in Note 1, and are not
intended to be a complete presentation of the World Savings Center Property's
revenues and expenses and may not be comparable to results from proposed future
operations of the World Savings Center.

          In our opinion, the combined statements of revenues and certain
operating expenses referred to above present fairly, in all material respects,
the revenues and certain operating expenses described in Note 1 for the years
ended December 31, 1996, 1995 and 1994 in conformity with generally accepted
accounting principles.

the year ended December 31, 1996 relate to the operations of the World Savings
Center (the "Property"). A mortgage note collateralized by the Property was
acquired by the Company subsequent to June 30, 1997 from an unaffiliated third-
party for an aggregate purchase price of $37.5 million. The Company has
negotiated a deed in lieu of foreclosure transaction, for no consideration,
which provides for the conveyance of the Property, currently held by a
partnership for which an affiliated party (Prentiss Properties WSC, Inc.) is the
general partner, to be transferred to the Operating Partnership in an arms
length transaction on or around January 1, 1998.  The World Savings Center
consists of one Class "A" suburban office building in Oakland, California
totaling approximately 271,055 net rentable square feet.

          The accompanying combined statements exclude certain expenses such as
interest, depreciation and amortization and other costs not directly related to
the future operations of the Property that may not be comparable to the expenses
expected to be incurred in the proposed future operations of the Property.
Management is not aware of any material factors relating to the Property which
would cause the reported financial information not to be necessarily indicative
of future operating results.

          The combined statements of revenues and certain operating expenses
have been prepared on the accrual basis of accounting.

    REVENUE AND EXPENSE RECOGNITION

          Rental income is recorded when due from tenants. The effects of
scheduled rent increases and rental concessions, if any, are recognized on a
straight-line basis over the term of the tenant's lease.

          During the year ended December 31, 1996, two separate tenants
represented 54% and 19%, respectively, of total base rental income.

    FUTURE RENTAL REVENUES

          The Property is leased to tenants under net operating leases. Minimum
lease payments receivable, excluding tenant reimbursement of expenses, under
noncancellable operating leases in effect as of December 31, 1996, are
approximately as follows:

          Office space in the World Savings Center is generally leased to
tenants under lease terms which provide for tenants to pay for increases in
operating expenses in excess of specified amounts.

    USE OF ESTIMATES

          The preparation of the combined statements of revenues and certain
operating expenses requires management to make estimates and assumptions that
affect the reported amounts, revenues and certain operating expenses during the
reporting period. Actual results could differ from those estimates.

2.  RELATED PARTY TRANSACTIONS

          Under terms of the management agreement, the World Savings Center paid
$210,944, $222,141, and $224,287 in management fees during the years ended
December 31, 1996, 1995, and 1994 , respectively, to an affiliate of the entity
owning the Property.

          The World Savings Center received base rents in the amount of
$2,530,827 during each of the years ended December 31, 1996, 1995, and 1994
pursuant to a lease agreement with World Savings and Loan which held an
ownership interest in the Property.  This lease expires in November 2000.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Trustees and Shareholders of
     Prentiss Properties Trust

          We have audited the accompanying combined statement of revenues and
certain operating expenses of the Selected Properties Acquired Subsequent to
June 30, 1997 (see Note 1) for the year ended December 31, 1996. The statement
of revenues and certain operating expenses is the responsibility of the Selected
Properties' Acquired Subsequent to June 30, 1997 owners. Our responsibility is
to express an opinion on the combined statement of revenues and certain
operating expenses based on our audit.

          We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined statement of revenues and
certain operating expenses is free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the combined statement of revenues and certain operating expenses. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall presentation of the combined
statement of revenues and certain operating expenses. We believe that our audit
provides a reasonable basis for our opinion.

          The accompanying combined statement of revenues and certain operating
expenses was prepared for the purpose of complying with rules and regulations of
the Securities and Exchange Commission, as described in Note 1, and is not
intended to be a complete presentation of the Selected Properties' Acquired
Subsequent to June 30, 1997 revenues and expenses and may not be comparable to
results from proposed future operations of the Selected Properties Acquired
Subsequent to June 30, 1997.

          In our opinion, the combined statement of revenues and certain
operating expenses referred to above presents fairly, in all material respects,
the revenues and certain operating expenses described in Note 1 for the year
ended December 31, 1996, in conformity with generally accepted accounting
principles.

          The following unaudited pro forma consolidated statement of income is
presented as if (i) the acquisition of the assets acquired during 1997, (the

1997.

          This pro forma consolidated statement of income should be read in

and pro forma consolidated statement of income for the year ended December 31,
1996 included elsewhere in this Form 8-K and the historical consolidated and
combined financial statements and notes thereto of the Company and the
Predecessor Company included in the Company's Form 10-K for the year ended

          The pro forma consolidated statement of income is not necessarily

Borrowing shall bear interest, if applicable, at an annual rate equal to the
lesser of (a) the Base Rate or the Eurodollar Rate plus one and three-quarters
of one percent (1.75%) (in each case as designated or deemed designated by

designated by Borrower), and (b) the Maximum Rate.  Each change in the Base Rate
and the Maximum Rate is effective, without notice to Borrower or any other
Person, upon the effective date of change.

A.      SELECTION OF INTEREST OPTION.

    (a) When Borrower requests any Eurodollar Borrowing, Borrower shall elect
the applicable interest period (each an "INTEREST PERIOD"), which may be, at
Borrower's option, one (1), two (2), or three (3) months during the period of
time from the date hereof to the Scheduled Maturity Date, and one (1), two (2),
three (3), or six (6) months during the period of time from the Scheduled
Maturity Date to the Extended Maturity Date, if applicable, subject to the
following conditions: (i) each Interest Period applicable to any Borrowing
commences on the day on or after the day when the next preceding applicable
Interest Period expires; (ii) 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; and (iii) no Interest
Period for any portion of Term Loans may extend beyond the scheduled repayment
date for that portion of the Term Loans.
 
<PAGE>
 
    (b) Borrower may (i) on the last day of the applicable Interest Period (or
at any other time, subject to payment of any Funding Loss) convert all or part
of a Eurodollar Borrowing to a Base Rate Borrowing, (ii) at any time convert all
or part of a Base Rate Borrowing to a Eurodollar Borrowing, and (iii) on the
last day of an Interest Period, elect a new Interest Period for a Eurodollar
Borrowing.  Any such conversion may be accomplished by delivering a Conversion
Request to Administrative Agent no later than 11:00 a.m. (A) on the third (3rd)
Business Day before (x) the conversion date for conversion to a Eurodollar
Borrowing, and (y) the last day of the Interest Period, for the election of a
new Interest Period, and (B) 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.

    (c) Notwithstanding anything to the contrary contained in this SECTION 3.4,
(i) each Eurodollar Borrowing with respect to the Term Loans shall be in a
minimum amount of $1,000,000.00 or a greater integral multiple of $100,000.00,
(ii) no more than five (5) Interest Periods shall be in effect at any one time
with respect to Eurodollar Borrowings, and (iii) Borrower may not request a
Eurodollar Borrowing if the interest rate applicable thereto under SECTION 3.3
would exceed the Maximum Rate in effect on the first day of the Interest Period
applicable to such Borrowing, but may give notice of the rate that it would have
selected, which notice shall be controlling for purposes of SECTION 3.7.

A.      DEFAULT RATE.  If permitted by applicable law, all past-due principal
and interest accruing on any of the foregoing bears interest from the date due
(stated or by acceleration) at the Default Rate until paid, regardless of
whether payment is made before or after entry of a judgment.

A.      INTEREST RECAPTURE.  If the designated interest rate applicable to any
Borrowing exceeds the Maximum Rate, then the interest rate on that Borrowing is
limited to the Maximum Rate, provided that 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.

A.      INTEREST CALCULATIONS.

1.      Interest shall 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 shall 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.

1.      The provisions of this Agreement relating to calculation of the Base
Rate and the Eurodollar Rate are included only for the purpose of determining
the rate of interest or 
<PAGE>
 
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.

A.      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 nor 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 any Agent or any Lender
ever does 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, Agents and the Lenders shall, to the maximum extent permitted under
applicable law, (a) treat all Borrowings as but a single extension of credit
(and the Lenders and Borrower agree that is the case and that provision in this
Agreement for multiple Borrowings is for convenience only), (b) characterize any
nonprincipal 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.  If, however, 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 the Lenders
shall refund any excess (and the Lenders may not, to the extent permitted by
applicable law, be subject to any penalties provided by any Governmental
Requirements for contracting for, charging, taking, reserving, or receiving
interest in excess of the Maximum Amount).  If the Governmental Requirements of
the State of Texas are applicable for purposes of determining the "Maximum Rate"
or the "Maximum Amount," then those terms mean the "weekly rate ceiling" from
time to time in effect under Article 5069-1.D, Title 79, Revised Civil Statutes
of Texas, as amended.
 
A.      ORDER OF APPLICATION.  Any payments (including proceeds from the
exercise of any Rights) shall be applied in the following order:  (a) to all
fees and expenses for which any Agent or the 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); (b) to accrued interest on the Term Loans; and (c) to
the remaining Obligation in the order and manner as the Required Lenders deem
appropriate.  Each payment or prepayment shall be distributed to each Lender in
accordance with its Pro Rata Share of such payment or prepayment.

A.      SHARING OF PAYMENTS, ETC.    If any Lender obtains any amount (whether
voluntary, involuntary, or otherwise) 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 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 applicable law, exercise all of its Rights of
payment with respect to that participation as fully as if such Lender were the
direct creditor of Borrower in the amount of that participation.

A.      BOOKING BORROWINGS.  To the extent permitted by applicable 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 3.13 than the
transferor Lender would have been entitled to receive with respect to those
Borrowings, and a transfer may not be made if, as a direct result of it, SECTION
<PAGE>
 
3.13 or 3.14 would apply to any of the Obligation.  If any of the conditions of
SECTIONS 3.13 or 3.14 ever apply to a Lender, then such Lender shall, to the
extent possible, carry or transfer its Borrowings at, to, or for the account of
any of its branch offices or the office or branch of any of its Affiliates so
long as the transfer is consistent with the other provisions of this SECTION,
does not create any burden or adverse circumstance for such Lender that would
not otherwise exist, and eliminates or ameliorates the conditions of SECTIONS
3.13 or 3.14 as applicable.

A.      BASIS UNAVAILABLE OR INADEQUATE FOR THE EURODOLLAR RATE.

1.      DETERMINATION BY ADMINISTRATIVE AGENT.  If Administrative Agent
determines that the basis for determining the applicable rate is not available,
Administrative Agent shall promptly notify Borrower and the Lenders of that
determination (which is conclusive and binding on Borrower absent manifest
error), and all Borrowings shall bear interest at the Base Rate.  Until
Administrative Agent notifies Borrower that such circumstances no longer exist,
the Lenders' commitments under this Agreement to make, or to convert to,
Eurodollar Borrowings shall be suspended.

1.      DETERMINATION BY LENDER.  If any Lender determines that for the Term
Loans made to Borrower hereunder and for other similar loans made by such Lender
to similar borrowers 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 such Lender shall promptly notify Administrative Agent and
Borrower, and all Borrowings of such Lender shall bear interest at the Base
Rate.  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 shall be suspended.

A.      ADDITIONAL COSTS.

1.      RESERVES.  With respect to any Eurodollar Borrowing, if (i) any change
in present Governmental Requirement, any change in the interpretation or
application of any present Governmental Requirement, or any future Governmental
Requirement imposes, modifies, or deems applicable (or if compliance by any
Lender with any such requirement of any Governmental Authority 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, 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 such Lender upon
demand.

1.      CAPITAL ADEQUACY.  With respect to any Borrowing, if any change in
present Governmental Requirement or any future Governmental Requirement
regarding capital adequacy or compliance by Administrative Agent or any Lender
with any request, directive or requirement now existing or hereafter imposed by
any Governmental Authority 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 
<PAGE>
 
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.

1.      TAXES.  Any Taxes payable by Administrative Agent or any Lender or ruled
(by a Governmental Authority) payable by Administrative Agent or any Lender in
respect of this Agreement or any other Loan Document shall, if permitted by
Governmental Requirement, be paid by Borrower, together with interest and
penalties, if any (except for Taxes imposed on or measured by the overall net
income of Administrative Agent or such 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.

1.      SURVIVAL.  The provisions of this SECTION 3.13 shall survive the
satisfaction and payment of the Obligation and termination of this Agreement.

A.      CHANGE IN GOVERNMENTAL REQUIREMENT.  If any Governmental Requirement
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
all Governmental Requirements, 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, Borrower shall promptly prepay the
Borrowing, without penalty, together with any related Funding Loss.

A.      FUNDING LOSS.  BORROWER AGREES TO INDEMNIFY EACH LENDER AGAINST, AND
PAY TO IT UPON DEMAND, ANY FUNDING LOSS OF SUCH 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 this SECTION
3.15 shall survive the satisfaction and payment of the Obligation and
termination of this Agreement.

A.      FOREIGN LENDERS.  Each Lender that is organized under the Governmental
Requirements 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 (2) 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 Governmental Requirement, duly executed
and completed by it, and (ii) comply from time to time with all Governmental
Requirements with regard 
<PAGE>
 
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.

A.      FEES.

1.      TREATMENT OF FEES.  The fees described in this SECTION 3.17 (i) are not
compensation for the use, detention, or forbearance of money, (ii) are in
addition to, and not in lieu of, interest and expenses otherwise described in
this Agreement, (iii) are payable in accordance with SECTION 3.1(b), (iv) are
non-refundable, (v) to the fullest extent permitted by applicable law, bear
interest, if not paid when due, at the Default Rate, and (vi) 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 3.17 are in all
events subject to the provisions of SECTION 3.8.

1.      AGENT FEES.  Borrower shall pay to each Agent, solely for their own
accounts, the fees described in the letter agreement between Borrower and Agents
dated the same date as this Agreement, as such letter agreement may be modified
or amended from time to time.

1.      EXTENSION FEE.  Upon extension of the Scheduled Maturity Date to the
Extended Maturity Date, as provided in SECTION 3.18, Borrower agrees to pay
Administrative Agent, on or before the Scheduled Maturity Date, for the ratable
account of Lenders, an extension fee equal to one-fourth of one percent (.25%)
of the outstanding principal balance of the Notes as of the Scheduled Maturity
Date.

A.      EXTENSION OF MATURITY DATE.  If no Default or Potential Default exists,
Borrower may request the extension of the Scheduled Maturity Date to the
Extended Maturity Date by making such request in writing (an "EXTENSION
REQUEST") to Administrative Agent at least forty-five (45) days prior to the
Scheduled Maturity Date. The Scheduled Maturity Date shall be extended to the
Extended Maturity Date only if: (a) all of the conditions precedent set forth in
SECTION 5 have been satisfied as of the Scheduled Maturity Date; (b) Borrower
pays to Administrative Agent the extension fee set forth in SECTION 3.17(c); (c)
Borrower grants to Administrative Agent first priority Liens in the Pool
Properties and provides Administrative Agent with Collateral Documents and such
documentation as Administrative Agent reasonably requests to show that Borrower
has good and marketable title to the Pool Properties; (d) the outstanding
principal balance of the Notes as of the Scheduled Maturity Date do not exceed
sixty-five percent (65%) of either (i) the Appraised Value of the Pool
Properties, or (ii) the Approved Cost of the Pool Properties; (e) as of the
Scheduled Maturity Date, the ratio of (i) Adjusted Net Operating Income, to (ii)
Assumed Debt Service, is not less than 1.25 to 1.0; and (f) as of the Scheduled
Maturity Date, no Material Adverse Event has occurred.

I.  SECTION   SECURITY.

A.      GUARANTY.  Each Guarantor shall, pursuant to a Guaranty, unconditionally
guarantee in favor of Agents and the Lenders the full payment and performance of
the Obligation.

A.      LIENS ON POOL PROPERTIES.  If, on the Scheduled Maturity Date, Borrower
has not repaid the unpaid principal of and interest on the Term Loans, then
Borrower and Pledgors 
<PAGE>
 
shall grant to Administrative Agent, for the benefit of the Lenders, as security
for the payment and performance of the Obligation, a valid, enforceable,
perfected, first priority, and (except for Permitted Liens) only Lien in and to
the Pool Properties.

A.       COLLATERAL DOCUMENTS.  The Liens described in SECTION 4.2 shall be
granted pursuant to, and more fully described in, the Collateral Documents,
which Administrative Agent can require Borrower to execute pursuant to SECTION
4.2.  Borrower shall be liable for, and shall reimburse Administrative Agent
for, all "due diligence" expenses related to the execution of such Collateral
Documents, including, but not limited to, attorneys' fees and recording
expenses.  Without limiting the foregoing, Borrower shall provide to
Administrative Agent, at Borrower's expense, a mortgagee policy of title
insurance for the Pool Properties and an appraisal of each Pool Property,
prepared in accordance with written instructions from Administrative Agent by a
third-party appraiser engaged directly by Administrative Agent.  If the unpaid
principal balance of the Term Loans has not been paid in full on or before
January __, 1998, then Borrower agrees that Agents may, at Borrower's expense,
commence due diligence with respect to the Pool Properties and preparation of
Collateral Documents.

A.       LEASES.  If the Liens described in SECTION 4.2 shall be granted
pursuant to, and more fully described in, the Collateral Documents, then all
leases with respect to the Pool Properties shall be subject to the provisions of
SECTION 4.3 of the Revolving Credit Agreement.

I.  SECTION   CONDITIONS PRECEDENT.

     (a) INITIAL ADVANCE.  Lenders will not be obligated to fund the Initial

Base Rate Borrowing to a Eurodollar Borrowing, (iii) continue any Eurodollar

and (C) such advance, Borrowing, or extension is permitted by all Governmental
Requirements.

     (e) GENERALLY.  Each condition precedent in this Agreement (including those

and time is of the essence with respect to each condition precedent.  Lenders
may fund any Borrowing without all conditions being satisfied, but, to the
extent permitted by Governmental Requirements, such funding 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 Lenders
specifically waive each item in writing.

I.  SECTION   REPRESENTATIONS AND WARRANTIES.  Borrower represents and
warrants to Agents and the Lenders as follows:

A.      PURPOSE OF CREDIT FACILITY.  Borrower shall use the proceeds of the
Initial Advance to pay a portion of the outstanding principal balance under the
Revolving Credit Agreement.  Borrower shall use the proceeds of the Second
Advance to acquire the Initial Terramics Pool Properties (or the stock,
partnership interests, or other ownership interests in one or more Pledgors of
the Initial Terramics Pool Properties).  Borrower shall use the proceeds of the
Third Advance to acquire the Secondary Terramics Pool Properties (or the stock,
partnership interests, or other ownership interest in one or more Pledgors of
the Secondary Terramics Pool Properties) or to refinance existing Liabilities
incurred in connection with the acquisition of the Secondary Terramics Pool
Properties (or the stock, partnership interests, or other ownership interest in
one or more Pledgors of the Secondary Terramics Pool Properties).  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 of the Term Loans shall be
used, directly or indirectly, for a purpose that violates any Governmental
Requirement, including the provisions of Regulation U.

A.      EXISTENCE, GOOD STANDING, AUTHORITY AND COMPLIANCE.  Each Obligor is
duly formed, validly existing and in good standing under the Governmental
Requirements of the jurisdiction in which it is incorporated or formed as
identified on the attached SCHEDULE 6.2 (as supplemented from time to time).
Each Obligor (a) is duly qualified to transact business and is in good standing
as a foreign trust, corporation, limited liability company, partnership, or
other entity in each jurisdiction where the nature and extent of its business
and properties require due qualification and good standing, which jurisdictions

to reflect changes as a result of transactions permitted by the Loan Documents),
except where the failure to so qualify could not result in a Material Adverse
Event, (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 Governmental Requirements.
<PAGE>
 
A.      AUTHORIZATION AND CONTRAVENTION.  The execution and delivery by each
Obligor of each Loan Document or related document to which it is a party, and

Documents, (e) do not violate any provision of any Governmental Requirement or
order of any Governmental Authority applicable to it, (f) do not violate any

or imposition of any Lien on any asset of any Company, other than pursuant to
the Loan Documents.

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

A.      FINANCIAL STATEMENTS; FISCAL YEAR.  The Current Financials were prepared
in accordance with GAAP and present fairly, in all material respects, the
consolidated financial condition, results of operations, and cash flows of the
Companies 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 the Companies 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 the Companies from that shown in the
Current Financials.  The fiscal year of each Company ends on December 31.

A.      LITIGATION.  Except as disclosed on the attached SCHEDULE 6.6, no
Company is subject to, or aware of the threat of, any Litigation that is
reasonably likely to be determined adversely to such Company or the Companies,
taken as a whole or, if so adversely determined, is a Material Adverse Event.
No outstanding and unpaid final and non-appealable judgments against any Company
exist which could result in a Material Adverse Event.

A.      TAXES.

1.      All Tax returns of each Company required to be filed have been filed
(or extensions have been granted) before delinquency, and all Taxes imposed upon
each Company 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.

1.      As of the date hereof, no United States federal income tax returns of
the "affiliated group" (as defined in the Code) of which any Company 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 (except
for taxes being contested in good faith by appropriate proceedings diligently
conducted and for which reserves in accordance with GAAP or otherwise acceptable
to Administrative Agent have been provided).  The charges, accruals and reserves
on the books of the Companies in respect of taxes or other governmental charges
are, in the opinion of the Companies, adequate.

materially and adversely affects any Pool Property, (b) no Obligor has received
any report of any Obligor's violation of any Environmental Law that has not been
remedied, (c) no Obligor knows that any Obligor is under any obligation to
remedy any violation of any Environmental Law, or (d) no Pool Property of any
Obligor is used for, or to the knowledge of Borrower 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 Obligor has taken prudent steps to
determine that each Pool Property does not violate any Environmental Law.

A.      EMPLOYEE PLANS.  Except where occurrence or existence could not
reasonably be expected to result in a Material Adverse Event, (a) no Employee
Plan has incurred an "accumulated funding deficiency" (as defined in Section 302
of ERISA or Section 412 of the Code), (b) no Company has incurred liability
under ERISA to the PBGC in connection with any Employee Plan (other than
required insurance premiums, all of which have been paid), (c) no Company has
withdrawn in whole or in part from participation in a Multiemployer Plan, (d) no
Company has engaged in any "prohibited transaction" (as defined in Section 406
of ERISA or Section 4975 of the Code), and (e) no "reportable event" (as defined
in Section 4043 of ERISA) has occurred, excluding events for which the notice
requirement is waived under applicable PBGC regulations.

A.      PROPERTIES; LIENS.  Each Company has good title to all of its
properties reflected in the Current Financials (except for properties that are
obsolete or that have been disposed in the ordinary course of business or, after
the date of this Agreement, as otherwise permitted by SECTION 8.8 or SECTION
8.9).

A.      LOCATIONS.  Each Obligor's chief executive office is located at the

Investment Company Act of 1940, as amended, or the Public Utility Holding
Company Act of 1935, as amended.

A.      TRANSACTIONS WITH AFFILIATES.  Except as disclosed on SCHEDULE 6.13
(as supplemented from time to time if the disclosures are approved by
Administrative Agent), no Company 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.

A.      INSURANCE.  Each Company maintains with financially sound,
responsible, and reputable insurance companies or associations (or, as to
workers' compensation or similar 
<PAGE>
 
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.

A.      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 any Company that could reasonably be expected
to result in a Material Adverse Event exist.  All payments due from any Company
for employee health and welfare insurance have been paid or accrued as a
liability on its books, other than any nonpayments that are not, individually or
collectively, a Material Adverse Event.

A.      SOLVENCY.  Each Obligor is, and after giving effect to the Term Loans,

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 existence of which or the
omission of which could be or result in a Material Adverse Event

A.      EXEMPTION FROM ERISA; PLAN ASSETS.  PPT is a "real estate operating
company" within the meaning of 29 C.F.R. (S) 2510.3-101(e) (or any successor
regulation) and the assets of the Companies would not be deemed "plan assets" as
defined in 29 C.F.R. (S) 2510.3-101(a)(1) (or any successor regulation) of any
Employee Plan or Multiemployer.

after entry, to pay, bond, or otherwise discharge any judgment or order for the

I.  SECTION   RIGHTS AND REMEDIES.

A.      REMEDIES UPON DEFAULT.

1.      DEBTOR RELIEF.  If a Default (i) occurs under SECTION 10.3(c) or (ii)
occurs and is continuing under SECTION 10.3(a), (b) OR (d), then the entire
unpaid balance of the Obligation automatically becomes due and payable without
any action of any kind whatsoever.

1.      OTHER DEFAULTS.  If a Default occurs and is continuing, subject to the
terms of SECTION 13.9(b), then Administrative Agent, upon the request of the
Required Lenders, 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) reduce any
claim to judgment; and (iii) exercise any and all other legal or equitable
Rights afforded by the Loan Documents, the Governmental Requirements of the
State of Texas, or any other applicable jurisdiction.

A.      WAIVERS.    To the extent permitted by applicable law, each Company
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.

A.      PERFORMANCE BY ADMINISTRATIVE AGENT.  If any covenant, duty, or
agreement of Borrower is not performed in accordance with the terms of the Loan
Documents, Administrative Agent may, while a Default exists, at its option,
perform, or attempt to perform that covenant, duty, or agreement on behalf of
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, neither
Administrative Agent nor 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.

A.      NOT IN CONTROL.  None of the covenants or other provisions contained
in any Loan Document shall, or shall be deemed to, give Agents or the Lenders
the Right to exercise control over the assets (including real property),
affairs, or management of any Company.

A.      COURSE OF DEALING.  The acceptance by Agents or any Lender of any
partial payment on the Obligation shall not be deemed to be a waiver of any
Default then existing.  No waiver by any Agent or any Lender of any Default
shall be deemed to be a waiver of any other then-existing or subsequent Default.
No delay or omission by any Agent or any Lender in exercising any Right under
the Loan Documents will impair that Right or be construed as a waiver 
<PAGE>
 
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.

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

A.      APPLICATION OF PROCEEDS.  Any and all proceeds ever received by any
Agent or any Lender from the exercise of any Rights pertaining to the Obligation
shall be applied to the Obligation according to SECTION 3.4.

A.      CERTAIN PROCEEDINGS.  Borrower shall promptly execute and deliver, or
cause the execution and delivery of, all applications, certificates,
instruments, and all other documents and papers any Agent reasonably requests in
connection with the obtaining of any consent, approval, registration,
qualification, permit, license, or authorization of any Governmental Authority
or other Person necessary or appropriate for the effective exercise of any
Rights under the Loan Documents.  Because Borrower agrees that Agents' and the
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.

I.  SECTION   AGENTS AND THE LENDERS.

A.      AGENTS.

1.      APPOINTMENT.  Each Lender appoints Administrative Agent (including,
without limitation, each successor Agent in accordance with this SECTION 12) as
its nominee and agent to act in its name and on its behalf (and Administrative
Agent and each such successor accepts that appointment):  (i) to act as its
nominee and on its behalf in and under all Loan Documents; (ii) to arrange the
means whereby its funds are to be made available to Borrower under the Loan
Documents; (iii) to take any action that it properly requests under the Loan

(whether voluntary or otherwise) in accordance with the terms of the Loan
Documents; and (vii) 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 Governmental Requirement.

1.      SUCCESSOR.  Administrative Agent may assign all of its Rights and
obligations as Administrative Agent under the Loan Documents to any of its
Affiliates, which Affiliate shall then be the successor Administrative Agent
under the Loan Documents.  Administrative Agent may also voluntarily resign by
giving thirty (30) days' prior written notice to Borrower and Lenders, and shall
resign upon the request of the Required Lenders for cause (i.e., Administrative
Agent is continuing to fail to perform its responsibilities as Administrative
Agent under the Loan Documents).  If the initial or any successor Administrative
Agent ever ceases to be 
<PAGE>
 
a party to this Agreement or if the initial or any successor Administrative
Agent ever resigns (whether voluntarily or at the request of the Required
Lenders), then the Required Lenders shall (which, if no Default or Potential
Default exists, is subject to Borrower's approval that may not be unreasonably
withheld) appoint the successor Administrative Agent from among the Lenders
(other than the resigning Administrative Agent). If the Required Lenders fail to
appoint a successor Administrative Agent within thirty (30) days after the
resigning Administrative Agent has given notice of resignation or the Required
Lenders have removed the resigning Administrative Agent, then the resigning
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative 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 commercial bank having a combined capital and surplus of at least
$1,000,000,000.00 (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 Baa1 by Moody's or BBB+ by 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 or
removal 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. If Borrower fails to respond
to any written request for any consent required in this SECTION 12.1(b) within
ten (10) days after the date that Borrower receives such request, then Borrower
shall be deemed to have given its consent to such request.

1.      RIGHTS AS LENDER.  Each Agent, in its capacity as a Lender, has the same
Rights under the Loan Documents as any other Lender and may exercise those
Rights as if it were not acting as an Agent.  The term "Lender," unless the
context otherwise indicates, includes Agents.  Administrative Agent's
resignation or removal does not impair or otherwise affect any Rights that it
has or may have in its capacity as an individual Lender.  Each Lender and
Borrower agree that Agents are not a fiduciary for Lenders or for Borrower but
are simply acting in the capacities described in this Agreement to alleviate
administrative burdens for Borrower and Lenders, that Agents have no duties or
responsibilities to Lenders or Borrower except those expressly set forth in the
Loan Documents, and that each Agent in its capacity as a Lender has the same
Rights as any other Lender.

1.      OTHER ACTIVITIES.  Any Agent or any Lender may now or in the future be
engaged in one or more loan, letter of credit, leasing, or other financing
transactions with Borrower or another Company, act as trustee or depositary for
Borrower or another Company, or otherwise be engaged in other transactions with
Borrower (collectively, the "OTHER ACTIVITIES") not the subject of the Loan
Documents.  Without limiting the Rights of Lenders specifically set forth in the
Loan Documents, no Agent nor any Lender is responsible to account to the other
Lenders for those other activities, and no Lender shall have any interest in any
other Lender's activities, any present or future guaranties by or for the
account of Borrower that are not contemplated by or included in the Loan
Documents, any present or future offset exercised by any Agent or any Lender in
respect of those other activities, any present or future property taken as
security for any of those other activities, or any property now or hereafter in
any Agent's or any other Lender's possession or control that may be or become
security for the obligations of Borrower arising under the Loan Documents by
reason of the general description of indebtedness secured or of property
contained in any other agreements, documents, or instruments related to any of
those other activities (but, if any payments in respect of those guaranties or
that property or the proceeds thereof is applied by any 
<PAGE>
 
Agent or any Lender to reduce the Obligation, then each Lender is entitled to
share ratably in the application as provided in the Loan Documents).

1.      DOCUMENTATION AGENT.  Documentation Agent 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, the 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
$1,000,000,000.00 (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 Baa1 by Moody's or BBB+ by S & P.

B.      EXPENSES.  Should Administrative Agent commence any proceeding or in
any way seek to enforce its Rights under the Loan Documents, each Lender, upon
demand therefor from time to time, shall contribute its share (based on its Pro
Rata Share) of the reasonable costs and/or expenses of any such enforcement or
acquisition, including, but not limited to, fees of receivers or trustees, court
costs, title company charges, filing and recording fees, appraisers' fees and
fees and expenses of attorneys to the extent not otherwise reimbursed by
Borrower.  Without limiting the generality of the foregoing, each Lender shall
contribute its share (based on its Pro Rata Share) of all reasonable costs and
expenses incurred by Administrative Agent (including reasonable attorneys' fees
and expenses) if Administrative Agent employs counsel for advice or other
representation (whether or not any suit has been or shall be filed) with respect
to any of the Loan Documents, or to enforce any rights of Administrative Agent
or any of Borrower's or any other Company's obligations under any of the Loan
Documents, but not with respect to any dispute between Administrative Agent and
any other Lender(s). Any loss of principal and interest resulting from any
Default shall be shared by Lenders in accordance with their respective Pro Rata
Shares. It is understood and agreed that Administrative Agent determines that it
is necessary to engage counsel for the Lenders from and after the occurrence of
a Potential Default or Default, said counsel shall be selected by Administrative
Agent and written notice of the same shall be delivered to the Lenders.

A.      PROPORTIONATE ABSORPTION OF LOSSES.  Except as otherwise provided in
the Loan Documents, nothing in the Loan Documents gives any Lender any advantage
over any other Lender insofar as the Obligation is concerned or relieves any
Lender from ratably absorbing any losses sustained with respect to the
Obligation (except to the extent unilateral actions or inactions by any Lender
result in Borrower or any other obligor on the Obligation having any credit,
allowance, setoff, defense, or counterclaim solely with respect to all or any
part of that Lender's Pro Rata Share of the Obligation).

A.      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 that 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 
<PAGE>
 
any request, authorization, consent, or approval of any Lender is conclusive and
binding on each subsequent holder, assignee, or transferee of or Participant in
that 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.

A.      LIMITATION OF AGENTS' LIABILITY.

1.      EXCULPATION.  No Agent nor any of their Affiliates or 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 nor any of its Affiliates
or 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).

1.      INDEMNITY.  Unless indemnified to its satisfaction against loss, cost,
liability, and expense, no Agent may 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 an Agent requests instructions from the Lenders, or the Required
Lenders, as the case may be, with respect to any act or action in connection
with any Loan Document, such 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 any 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 any Agent as a result of such Agent's acting or refraining from acting
under this Agreement in accordance with instructions of the Required Lenders.

1.      RELIANCE.  No Agent is not responsible to any Lender or any Participant
for, and each Lender represents and warrants that it has not relied upon any
Agent in respect of, (i) the creditworthiness of Borrower or PPT and the risks
involved to that Lender, (ii) the effectiveness, enforceability, genuineness,
validity, or the due execution of any Loan Document (except by such Agent),
(iii) any representation, warranty, document, certificate, report, or statement
made therein (except by such Agent) or furnished thereunder or in connection
therewith, (iv) observation of or compliance with any of the terms, covenants,
or conditions of any Loan Document on the part of any Company.  EACH LENDER
AGREES TO INDEMNIFY  EACH AGENT AND ITS REPRESENTATIVES AND HOLD THEM HARMLESS
FROM AND AGAINST (BUT LIMITED TO SUCH LENDER'S PRO RATA SHARE 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  SUCH AGENT AND ITS REPRESENTATIVES
ARE NOT REIMBURSED FOR SUCH AMOUNTS BY ANY COMPANY.  ALTHOUGH EACH AGENT AND
ITS REPRESENTATIVES HAVE THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR
ITS OR THEIR OWN ORDINARY NEGLIGENCE, EACH AGENT 
<PAGE>
 
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.

A.      DEFAULT.  While a Default exists, the Lenders agree to promptly confer
in order that the Required Lenders or the Lenders, as the case may be, may agree
upon a course of action for the enforcement of the Rights of the Lenders.
Administrative Agent is entitled to act or refrain from taking any action
(without incurring any liability to any Person for so acting or refraining)
unless and until it has received instructions from Required Lenders.  In actions
with respect to any Company's property, Administrative Agent is acting for the
ratable benefit of each Lender.

A.      COLLATERAL MATTERS. So long as Borrower grants to Administrative
Agent, for the benefit of Lenders, a Lien in the Pool Properties as provided in
SECTION 4.2 herein:

    (a) Each Lender authorizes and directs Administrative Agent to enter into
the Loan Documents and agrees that any action taken by Administrative Agent
concerning the Collateral (with the consent or at the request of the Required
Lenders) in accordance with any Loan Document, that Administrative Agent's
exercise (with the consent or at the request of the Required Lenders) of powers
concerning the Collateral in any Loan Document, and that all other reasonably
incidental powers are authorized and binding upon all Lenders.

    (b) Administrative Agent is authorized on behalf of all Lenders, without
the necessity of any notice to or further consent from any Lender, from time to
time before a Default or Potential Default, to take any action with respect to
any Collateral or Loan Documents related to the Collateral that may be necessary
to perfect and maintain Administrative Agent's Liens in the Collateral,
including, without limitation, making Protective Advances; provided, however,
Administrative Agent shall not, without the consent of the Required Lenders,
make any Protective Advances during any one (1) calendar year in excess of the
sum of (i) amounts expended to pay real estate taxes, assessments, and
governmental charges or levies imposed upon the Collateral, (ii) amounts
expended to pay insurance premiums for policies of insurance related to the
Collateral, and (iii) $250,000.00.

    (c) Except to use the same standard of care that it ordinarily uses for
collateral for its sole benefit, Administrative Agent has no obligation
whatsoever to any Lender or to any other Person to assure that the Collateral
exists or is owned by any Company or is cared for, protected, or insured or has
been encumbered or that Administrative Agent's Liens, if applicable, have been
or will be properly or sufficiently or lawfully created, perfected, protected,
or enforced or are entitled to any particular priority.

    (d) Administrative Agent shall exercise the same care and prudent judgment
with respect to the Collateral and the Loan Documents as it normally and
customarily exercises in respect of similar collateral and security documents.

    (e) Lenders irrevocably authorize Administrative Agent, at its option and
in its discretion, to release any Liens upon any Collateral (i) constituting
property being disposed of as permitted under any Loan Document or (ii) if
approved, authorized, or ratified in writing by the Required Lenders.  Upon
request by Administrative Agent at any time, Lenders shall confirm in writing
Administrative Agent's authority to release particular Collateral under this
CLAUSE (e).

    (f) In the event any or all of the Collateral is acquired by Administrative
Agent as the result of a foreclosure or the acceptance of a deed or assignment
in lieu of foreclosure, or is 
<PAGE>
 
retained in satisfaction of all or any part of the Obligation, title to any such
Collateral or any portion thereof shall be held in the name of Administrative
Agent or a nominee or subsidiary of Administrative Agent (which in any case is
authorized to do business in the state in which such Collateral is located), as
agent, for the ratable benefit of Administrative Agent and the Lenders.
Administrative Agent shall prepare a recommended course of action for such
Collateral (the "POST-FORECLOSURE PLAN"), which shall be subject to the approval
of the Required Lenders, or shall take such action as directed by the Required
Lenders. Administrative Agent shall manage, operate, repair, administer,
complete, construct, restore, or otherwise deal with the Collateral acquired and
administer all transactions relating thereto, including, without limitation,
employing a management agent and other agents, contractors, and employees,
including agents of the sale of such Collateral, and the collecting of rents and
other sums from such Collateral and paying the expenses of such Collateral. Upon
demand therefor from time to time, each Lender will contribute its share (based
on its Pro Rata Share) of all reasonable costs and expenses incurred by
Administrative Agent pursuant to the Post-Foreclosure Plan in connection with
the construction, operation, management, maintenance, leasing and sale of such
Collateral. In addition, Administrative Agent shall render or cause to be
rendered by the managing agent, to each of the Lenders, monthly, an income and
expense statement for such Collateral, and each of the Lenders shall promptly
contribute its Pro Rata Share of any operating loss for such Collateral, and
such other expenses and operating reserves as Administrative Agent shall deem
reasonably necessary pursuant to and in accordance with the Post-Foreclosure
Plan. To the extent there is net operating income from such Collateral,
Administrative Agent shall, in accordance with the Post-Foreclosure Plan,
determine the amount and timing of distributions to the Lenders. All such
distributions shall be made to the Lenders in accordance with their respective
Pro Rata Shares. The Lenders acknowledge that if title to any Collateral is
obtained by Administrative Agent or its nominee, such Collateral will not be
held as a permanent investment but will be liquidated as soon as practicable.
Administrative Agent shall undertake to sell such Collateral, at such price and
upon such terms and conditions as the Required Lenders shall reasonably
determine to be most advantageous. Any purchase money mortgage or deed of trust
taken in connection with the disposition of such Collateral in accordance with
the immediately preceding sentence shall name Administrative Agent, as agent for
the Lenders, as the beneficiary or mortgagee. In such case, Administrative Agent
and the Lenders shall enter into an agreement with respect to such purchase
money mortgage defining the rights of the Lenders in the same Pro Rata Shares as
provided hereunder, which agreement shall be in all material respects similar to
this Agreement insofar as this Agreement is appropriate or applicable.

A.      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.

A.      RELATIONSHIP OF LENDERS.  The Loan Documents do not create a
partnership or joint venture among Agents and the Lenders or among the Lenders.

A.      BENEFITS OF AGREEMENT.  None of the provisions of this SECTION inure
to the benefit of any Company or any other Person except Agents and the Lenders.
Therefore, no Company nor any other Person is responsible or liable for,
entitled to rely upon, or entitled to raise as a defense -- in any manner
whatsoever -- the failure of any Agent or any Lender to comply with these
provisions.
<PAGE>
 
A.      APPROVAL OF LENDERS.

1.      All communications from Administrative Agent to the Lenders requesting
the Lenders' determination, consent, approval, or disapproval (i) shall be given
in the form of a written notice to each Lender, (ii) shall be accompanied by a
description of the matter or thing as to which such determination, approval,
consent, or disapproval is requested, or shall advise each Lender where such
matter or thing may be inspected, or shall otherwise describe the matter or
issue to be resolved, (iii) shall include, if reasonably requested by a Lender
and to the extent not previously provided to such Lender, written materials and
a summary of all oral information provided to Administrative Agent by Borrower
in respect of the matter or issue to be resolved, and (iv) shall include
Administrative Agent's recommended course of action or determination in respect
thereof.  Each Lender shall reply promptly, but in any event (x) within thirty
(30) days (or such lesser period as may be required under the Loan Documents for
Administrative Agent to respond) for those matters requiring the consent by all
Lenders, and (y) within fifteen (15) Business Days (or such lesser period as may
be required under the Loan Documents for Administrative Agent to respond) for
those matters requiring the consent by the Required Lenders, in each instance,
after receipt of the request therefore by Administrative Agent (in either event,
the "LENDER REPLY PERIOD").

1.      Unless a Lender shall give written notice to Administrative Agent that
it objects to the recommendation or determination of Administrative Agent
(together with a written explanation of the reasons behind such objection)
within the Lender Reply Period, such Lender shall be deemed to have approved of
or consented to such recommendation or determination.

I.  SECTION   MISCELLANEOUS.

A.      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.

A.      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.

A.      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 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 the attached SCHEDULE
1.
<PAGE>
 
A.      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 Agents and their counsel.

A.      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.

A.      GOVERNING LAW.  Except as expressly provided in a Loan Document, the
Governmental Requirements (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.

A.      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, the 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 applicable 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.

A.      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 COUNTY, TEXAS, OR IN THE UNITED
STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF TEXAS, DALLAS 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 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 
<PAGE>
 
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 Administrative Agent's and each Lender's agreement to enter into a
business relationship, that Administrative Agent and each Lender has already
relied on these waivers in entering into this Agreement, and that Administrative
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.

A.      AMENDMENTS, CONSENTS, CONFLICTS AND WAIVERS.

1.      REQUIRED LENDERS.  Unless otherwise specifically provided, (i) the
provisions of this Agreement may be amended, modified, or waived, only by an
instrument in writing executed by Borrower and the Required Lenders and
supplemented only by documents delivered or to be delivered in accordance with
the express terms of this Agreement, and (ii) the Collateral Documents may only
be the subject of an amendment, modification, or waiver that has been approved
by Administrative Agent and Borrower.

1.      ALL LENDERS.  Except as specifically otherwise provided in this SECTION
13.9, any amendment to or consent or waiver under this Agreement or any Loan
Document that purports to accomplish any of the following must be by an
instrument in writing executed by Borrower and executed (or approved, as the
case may be) by each Lender: (i) extends the Scheduled Maturity Date or the
Extended Maturity Date; (ii) extends the due date or decreases the amount of any
scheduled payment or amortization of the Obligation beyond the date specified in
the Loan Documents; (iii) decreases any rate or amount of interest, fees, or
other sums payable to Agents or Lenders under this Agreement (except such
reductions as are contemplated by this Agreement); (iv) changes the definition
of "TERM LOAN," "TERM LOANS," "REQUIRED LENDERS," or "PRO RATA SHARE"; (v)
increases any one or more Lenders' Loans; (vi) waives compliance with, amends,
or fully or partially releases any Guaranty or any Collateral except as set
forth in SECTION 8.3; (vii) permits any Obligor to assign any of its Rights or
obligations hereunder or under any of the Loan Documents; (viii) waives or
amends any of the conditions precedent to the extension of the Scheduled
Maturity Date to the Extended Maturity Date set forth in SECTION 3.18(c); or
(ix) changes this CLAUSE (b) or any other matter specifically requiring the
consent of all Lenders under this Agreement.

1.      AGENTS.  No amendment, modification, consent or waiver which modifies
the rights, duties, or obligations of any Agent shall be effective without the
consent of such Agent.

1.      CONFLICTS.  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.

1.      COURSE OF DEALING.  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 
<PAGE>
 
in writing and signed by the Required Lenders or the Lenders, as appropriate, to
be effective, and a waiver will be effective only in the specific instance and
for the specific purpose for which it is given.

A.      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 the 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.

A.      SUCCESSORS AND ASSIGNS; PARTICIPATIONS.

1.      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 transfer, pledge, assign, sell
any participation in, or otherwise encumber its portion of the Obligation,
except as permitted by this SECTION 13.4.

1.      Subject to the provisions of this SECTION and in accordance with
applicable law, any Lender may, in the ordinary course of its commercial banking
business, at any time sell to one or more Eligible Assignees (each a
"PARTICIPANT") participating interests in its portion of the Obligation;
provided that each such participation is not less than $10,000,000.00.  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 Term Loans 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, or
reduces the interest rate or the amount of principal or fees applicable to the
Obligation (except reductions contemplated by this Agreement).  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.
Except in the case of the sale of a participating interest to another Lender,
the relevant participation agreement shall prohibit the Participant from
transferring, pledging, assigning, selling participations in, or otherwise
encumbering its portion of the Obligation.

1.      Subject to the provisions of this SECTION, any Lender having a Term Loan
equal to or greater than $10,000,000.00 may at any time, in the ordinary course
of its commercial banking business, (i) without the consent of Borrower or
Agents, assign all or any part of its Rights and obligations under the Loan
Documents to any of its Affiliates (each a "PURCHASER"), and (ii) upon the prior
written consent of Agents, and so long as no Default or Potential Default
exists, Borrower, such consents not to be unreasonably withheld, assign to any
Eligible Assignee (each of which is also a "PURCHASER") a proportionate part
(not less than $10,000,000.00 and an integral multiple of $1,000,000.00) of all
or any part of its Rights and obligations under the Loan Documents; provided
that unless the Lender granting such assignment is assigning all of its Term
Loan and Note hereunder, after giving effect to such assignment, the Lender
granting such assignment shall retain a Term Loan of at least $10,000,000.00.
Notwithstanding the foregoing, each Agent shall, at all times prior to its
resignation or replacement as an Agent hereunder, retain a minimum Term Loan of
$25,000,000.00. In each case, the Purchaser shall assume those Rights and
obligations under an assignment agreement substantially in the form of the
attached EXHIBIT E. Upon (i) delivery of an executed copy of the assignment
agreement to Borrower and Administrative Agent and (ii) payment of a fee of
$3,000.00 from the transferor to 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,
the Lenders or Administrative 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 Term Loan of
such Purchaser, Administrative Agent shall deliver to Borrower and the Lenders
an amended SCHEDULE 1 reflecting those changes, Borrower shall execute and
deliver to each of the transferor Lender and the Purchaser a Note in the face
amount of its respective Term Loan following transfer, and, upon receipt of its
new Note, the transferor Lender shall return to Borrower the 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.

1.      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.

1.      Until the Scheduled Maturity Date, each Agent shall identify and solicit
prospective Purchasers or Participants to be assignees of or participants in the
Rights and obligations of each Agent under this Agreement (in such capacity,
"SYNDICATING LENDERS") in an amount of up to $73,000,000.00. During such period,
the Syndicating Lenders shall (i) not solicit or enter into any such assignment
or participation except as provided in this SECTION 13.11(e), and (ii) refer
each prospective Purchaser or Participant that expresses an interest in
purchasing or acquiring any such assignment or participation to the other
Syndicating Lender.  Each Syndicating Lender, upon identifying any prospective
Purchaser or Participant desiring to be an assignee of or participant in any
portion of the Rights and obligations of the Syndicating Lenders under this
Agreement, shall deliver written notice to the other Syndicating Lender of the
terms of such transaction ("PROPOSED SYNDICATION TRANSACTION").  Each
Syndicating Lender shall have the right to participate in such Proposed
Syndication Transaction on the terms set forth in such notice by so notifying
the other Syndicating Lender within five (5) days of receiving such notice.  The
assignment or participation effected by such Proposed Syndication Transaction
shall be allotted equally to each participating Syndicating Lender.
Notwithstanding anything contained to the contrary in SECTION 13.11(c), the
aggregate assignments to a Purchaser by the Syndicating Lenders 
<PAGE>
 
shall be in an aggregate amount of not less $10,000,000.00 or a greater integral
multiple of $1,000,000.00.

1.      No Lender may assign or participate all or any portion of its Rights or
obligations under this Agreement to any Company or any Affiliate of any Company.

1.      Borrower acknowledges that the Syndicating Lenders may use their
Affiliates (other than a real estate development or management company) (and in
the case of Documentation Agent, may use NationsBanc Capital Markets, Inc.) to
assist in the syndication of their Rights and obligations under this Agreement.
Borrower acknowledges and consents that the Syndicating Lenders may share
information relating to Borrower, PPT, and the other Companies or the
transactions contemplated hereby with their respective Affiliates (other than a
real estate development or management company), and that such Affiliates may
likewise share information relating to Borrower, PPT, and the other Companies or
such transactions with the Syndicating Lenders.

A.      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 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.

A.      ENTIRETY.  THIS AGREEMENT AND THE OTHER WRITTEN LOAN DOCUMENTS (EACH
AS AMENDED IN WRITING FROM TIME TO TIME) EXECUTED BY BORROWER, ANY LENDER OR ANY
AGENT REPRESENT THE FINAL AGREEMENT AMONG BORROWER, THE LENDERS AND AGENTS AND
MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL
AGREEMENTS BY THE PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE
PARTIES.

A.      EFFECTIVENESS.  This Agreement is executed on October 6, 1997, but
shall not be effective until executed by all parties hereto and delivered to and
accepted by Administrative Agent, and the other conditions set forth in SECTION
5 have been satisfied or waived by the Lenders in writing.
