     On May 12, 1998 PIMCO Advisors L.P., a Delaware limited partnership ("PIMCO
Advisors") of which PIMCO Advisors Holdings L.P., a Delaware limited partnership
(the "Registrant") holds an approximate 43 percent interest, entered into
$500,000,000 credit facility consisting of (i) a Long-Term Credit Agreement,
dated as of May 12, 1998 (the "Long-Term Credit Agreement") among PIMCO
Advisors, NationsBank, N.A. ("Administrative Agent"), Deutsche Bank A.G., New
York Branch ("Documentation Agent") Union Bank of California, N.A. and CitiBank,
N.A. ("Co-Agents") and the financial institutions whose names are set forth on
the signature pages thereof, and (ii) a Short-Term Credit Agreement, dated as of
May 12, 1998 (the "Short-Term Credit Agreement") among PIMCO Advisors, the
Administrative Agent, the Documentation Agent, the Co-Agents and the financial
institutions whose names are set forth on the signature pages thereto.

     The Long-Term Credit Agreement provides for a $250,000,000 five year
revolving credit facility. The Short-Term Credit Agreement provides for a
$250,000,000 364-day revolving credit facility.  Loans under the credit
facilities may be Eurodollar Rate Loans or Alternative Base Rate Loans.
Eurodollar Rate Loans bear interest at the rate per annum at the London
interbank offered rate for deposits in dollars at approximately 11:00 a.m.
(London time) two days prior to the first day of the interest period, plus a
margin ranging, with respect to the Long-Term Credit Agreement, 0.25% to 0.425%,
and with respect to the Short-Term Credit Agreement, from 0.27% to 0.45%,
depending on the amount of leverage maintained by PIMCO Advisors.  Alternative
Base Rate Loans bear interest at the higher of (i) the prime rate of the
Administrative Agent, or (ii) the Federal Funds Effective Rate, plus one-half of
one percent.

     PIMCO Advisors intends to use proceeds of loans for acquisitions of other
businesses and general working capital purposes.  At this time PIMCO Advisors
has not drawn funds under the credit facilities.

the Administrative Agent, for the benefit of the Administrative Agent, the
Arranging Agents and the Banks, as the case may be, such fees as are mutually
agreed upon and as are described in the Fee Letters.

          (c) Computation of Fees.  In computing any fees payable under this
              -------------------

              -----------------------------                                    
at any time and from time to time upon three (3) Business Days' prior written
notice to the Administrative Agent to reduce by at least $10,000,000 or integral
multiples of $1,000,000 in excess thereof, or to terminate entirely, the
unborrowed portion of the Total Commitment, whereupon the Commitments of the
Banks shall be reduced pro rata in accordance with their respective Commitment
                       --------                                               
Percentages of the amount specified in such notice or, as the case may be,
terminated.  Promptly after receiving any notice of the Borrower delivered
pursuant to this Section 2.3, the Administrative Agent will notify the Banks of
the substance thereof.  Upon the effective date of any such reduction or
termination, the Borrower shall pay to the Administrative Agent for the
respective accounts of the Banks the full amount of any facility fee then
accrued on the amount of the reduction.  No reduction or termination of the
Commitments may be reinstated.
 
         2.4  The Notes.  The Loans shall be evidenced by separate promissory

Revolving Note shall be payable to the order of each Bank in a principal amount

Borrower irrevocably authorizes each Bank to make or cause to be made, at or
about the time of the Drawdown Date of any Loan or at the time of receipt of any
payment of principal on such Bank's Revolving Note, as the case may be, an
appropriate notation on such Bank's Record reflecting the making of such Loan or
(as the case may be) the receipt of such payment.  The outstanding amount of the
Loans set forth on such Bank's Record shall be prima facie evidence of the
                                               -----------                
principal amount thereof owing and unpaid to such Bank, but the failure to
record, or any error in so recording, any such amount on such Bank's Record
shall not limit or otherwise affect the obligations of the Borrower hereunder or
under any Revolving Note to make payments of principal of or interest on any
Revolving Note when due.

                  ---------------------------------                      
Applicable Margin with respect to any Loan outstanding under the Commitment

Agent written notice in the form of Exhibit B-1 hereto (or telephonic notice
                                    -----------

the Loan requested, (ii) the proposed Drawdown Date of such Loan, (iii) the Type
of such Loan, and (iv) the Interest Period for such Loan if such Loan is a
Eurodollar Rate Loan. Promptly upon receipt of any such Loan Request, the

Loan Request shall be in a minimum aggregate amount of $10,000,000 or in an

         2.7  Conversion Options.
              ------------------ 

              (a) Conversion to Eurodollar Rate Loan.  The Borrower may elect
                  ----------------------------------                         
from time to time, subject to Section 2.9, to convert any outstanding
Alternative Base Rate Loan to a Eurodollar Rate Loan, provided that (i) the
                                                      --------             
Borrower shall give the Administrative Agent at least three (3) Eurodollar
Business Days' prior written notice of such election; and (ii) no Alternative
Base Rate Loan may be converted into a Eurodollar Rate Loan when any Default has
occurred and is continuing.  The Administrative Agent shall notify the Banks
promptly of any such notice.  On the date on which such conversion is being
made, each Bank shall take such action as is necessary to transfer its
Commitment Percentage of such Loans to its Eurodollar Lending Office.  All or
any part of outstanding Alternative Base Rate Loans may be converted into a
Eurodollar Rate Loan as provided herein, provided that any partial conversion
shall be in an aggregate principal amount of $1,000,000 or an integral multiple
of $1,000,000 in excess thereof.

         (b)  Continuation of Type of Loan.
              ---------------------------- 

              (i)   All Alternative Base Rate Loans shall continue as
Alternative Base Rate Loans until converted into Eurodollar Rate Loans as
provided in Section 2.7(a).

              (ii)  Any Eurodollar Rate Loan may, subject to Section 2.9, be
continued, in whole or in part, as a Eurodollar Rate Loan upon the expiration of
the Interest Period with respect thereto, provided that (A) the Borrower shall
give the Administrative Agent at least three (3) Eurodollar Business Days' prior
written notice of such election; (B) no Eurodollar Rate Loan may be continued as
such when any Default has occurred and is continuing, but shall be automatically
converted to an Alternative Base Rate Loan on the last day of the first Interest
Period relating thereto ending during the continuance of any Default; and (iii)
any partial continuation of a Eurodollar Rate Loan shall be in an aggregate
principal amount of $1,000,000 or an integral multiple of $1,000,000 in excess
thereof.

              (iii) If the Borrower shall fail to give any notice of
continuation of a Eurodollar Rate Loan as provided under this Section 2.7(b),
the Borrower shall be deemed to have requested a conversion of the affected
Eurodollar Rate Loan to an Alternative Base Rate Loan on the last day of the
then current Interest Period with respect thereto.

              (iv)  The Administrative Agent shall notify the Banks promptly
when any such continuation or conversion contemplated by this Section 2.7(b) is
scheduled to occur. On the date on which any such continuation or conversion is
to occur, each Bank shall take such action as is necessary to transfer its
Commitment Percentage of such Loans to its Domestic Lending Office or its
Eurodollar Lending Office as appropriate.

         (c)  Conversion Requests.  All notices of the conversion or 
              -------------------                                   
continuation of a Loan provided for in this Section 2.7 shall be in writing in
the form of Exhibit D hereto (or shall be given by telephone and confirmed by a
            ---------
writing in the form of Exhibit E hereto). Each such notice shall specify (i) the
                       ---------
principal amount and Type of the Loan subject thereto, (ii) the date on which
the current Interest Period of such Loan ends if such Loan is a Eurodollar Rate
Loan, and (iii) the new Interest Period for such Loan if such Loan is a
Eurodollar Rate Loan. Promptly upon receipt of any such notice, the
Administrative Agent shall notify each of the Banks thereof. Each such notice
shall be irrevocable and binding on the Borrower.

         2.8  Funds for Loans.
              --------------- 

              (a) Funding Procedures.  Not later than 2:00 p.m. (Dallas time)
                  ------------------                                   
on the proposed Drawdown Date of any Loans, each of the Banks will make
available to the Administrative Agent, at its Head Office, in immediately
available funds, the amount of such Bank's Commitment Percentage of the amount
of the requested Loans. Upon receipt from each Bank of such amount, and upon
receipt of the documents required by Section 9 and the satisfaction of the other
conditions set forth therein, to the extent applicable, the Administrative Agent
will make available to the Borrower the aggregate amount of such Loans made
available to the Administrative Agent by the Banks. The failure or refusal of
any Bank to make available to the Administrative Agent at the aforesaid time and
place on any Drawdown Date the amount of its Commitment Percentage of the
requested Loans shall not relieve any other Bank from its several obligation
hereunder to make available to the

                                       22
<PAGE>
 
Administrative Agent the amount of such other Bank's Commitment Percentage of
any requested Loans, but no other Bank shall be liable in respect of the failure
of such Bank to make available such amount.

              (b) Advances by Administrative Agent.  The Administrative Agent
                  --------------------------------                           
may, unless notified to the contrary by any Bank prior to a Drawdown Date,
assume that such Bank has made available to the Administrative Agent on such
Drawdown Date the amount of such Bank's Commitment Percentage of the Loans to be
made on such Drawdown Date, and the Administrative Agent may (but it shall not
be required to), in reliance upon such assumption, make available to the
Borrower a corresponding amount.  If any Bank makes available to the
Administrative Agent such amount on a date after such Drawdown Date, such Bank
shall pay to the Administrative Agent on demand an amount equal to the weighted
average interest rate paid by the Administrative Agent for federal funds
acquired by the Administrative Agent during each day included in such period,
times the amount of such Bank's Commitment Percentage of such Loans calculated
on the basis of a 360-day year for the actual number of days elapsed.  A
statement of the Administrative Agent submitted to such Bank with respect to any
amounts owing under this paragraph shall be prima facie evidence of the amount
due and owing to the Administrative Agent by such Bank.  If the amount of such
Bank's Commitment Percentage of such Loans is not made available to the
Administrative Agent by such Bank within three (3) Business Days following such
Drawdown Date, the Administrative Agent shall be entitled to recover such amount
from the Borrower within one (1) Business Day after demand therefor, with
interest thereon at the rate per annum applicable to the Loans made on such
Drawdown Date.

         2.9  Limit on Number of Eurodollar Rate Loans.  At no time shall there
              ----------------------------------------                         
be outstanding Eurodollar Rate Loans having more than five (5) different
Interest Periods.

from time to time from the Closing Date until the Maturity Date for the purposes
hereinafter set forth; provided, however, (i) the aggregate amount of Swing
                       --------  -------

                          -----------

                ------------------                          
on the date of the requested Swing Loan Advance. Each such notice shall be
irrevocable and shall specify (i) that a Swing Loan Advance is requested, (ii)
the date of the requested Swing Loan Advance (which shall be a Business Day),
and (iii) the aggregate principal amount of the Swing Loan requested. The Swing
Loan Lender shall initiate the transfer of funds representing the Swing Loan

payable on the earliest of (i) the date thirty (30) days from the date of
advance thereof or (ii) the Maturity Date.  The Swing Loan Lender may, at any
time, in its sole discretion by written notice to the Borrower, require
repayment of the Swing Loans by way of an advance of a Loan, in which case the
Borrower shall be deemed to have requested an Alternative Base Rate Loan in the
amount of the respective Swing Loans; provided, however, that any such demand
                                      --------  -------

and on the date of the occurrence of any Event of Default hereunder and the
exercise of remedies in accordance with the provisions of Section 10.3 hereof.
Each Bank hereby irrevocably agrees to make such Loans promptly upon any such
request or deemed request in the amount and in the manner specified in the
preceding sentence and on the same such date notwithstanding (A) the amount of
                                             ---------------                  
such Loan may not comply with the minimum amount for Loans otherwise required
hereunder, (B) whether any conditions specified in Article 9 are then satisfied,
(C) whether a Default or an Event of Default then exists, (D) the failure of any
such request or deemed request for a Loan to be made by the time otherwise
required in Section 2.6 or (E) any reduction in the Commitment or termination of
the Commitment immediately prior to such advance or contemporaneously therewith.

              (e) Participations and Purchases of Swing Loans.  In the event
                  -------------------------------------------               
that any Loan cannot for any reason be made on the date otherwise required above
(including, without limitation, as a result of the commencement of a Proceeding
of the kind referred to in Sections 10.1(h) or 10.1(i) with respect to the
Borrower or any other obligor hereunder), then each Bank hereby agrees that it
shall forthwith purchase (as of the date such advance of a Loan would otherwise
have occurred, but adjusted for any payments received from the Borrower on or
after such date and prior to such purchase) from the Swing Loan Lender such
participations in the outstanding Swing Loans as shall be necessary to cause
each such Bank to share in such Swing Loans ratably based upon its respective
Commitment Percentage (determined before giving effect to any termination of the
Commitment pursuant to Article 10), provided that (i) all interest payable on
                                    --------                                 
the Swing Loans shall be for the account of the Swing Loan Lender until the date
the respective participation is purchased but upon such purchase the purchasing
Bank shall be entitled to all interest from and including the date upon which
the advance would otherwise have occurred, and (ii) at the time any purchase of
participations pursuant to this sentence is actually made, the purchasing Bank
shall be required to pay to the Swing Loan Lender interest on the principal
amount of participation purchased for each day from and including the day upon
which the advance of a Loan would otherwise have occurred to but excluding the
date of payment for such participation, at the rate equal to, if paid within two
(2) Business Days of the date of such advance, the Federal Funds Effective Rate,
and thereafter at a rate equal to the Alternative Base Rate.

evidenced by the Swing Loan Note in the form of Exhibit A-2 hereto.  The Swing

outstanding amount of the Loans exceeds the Commitment, then the Borrower shall
immediately pay the amount of such excess to the Administrative Agent for
application to the Loans.

         3.3 Optional Repayments of Loans.  The Borrower shall have the right,
             ----------------------------                                     
at its election, to repay the outstanding amount of the Loans, as a whole or in
part, at any time without penalty or premium, provided that any full or partial
repayment of the outstanding amount of any Eurodollar Rate Loans pursuant to
this Section 3.3 made on a date other than the last day of the Interest Period
relating thereto shall be subject to customary breakage charges as provided in
Section 4.9.  The Borrower shall give the Administrative Agent, no later than
10:00 a.m. (Dallas time) at least one (1) Business Day's prior written notice,
of any proposed repayment pursuant to this Section 3.3 of Alternative Base Rate
Loans, and three (3) Eurodollar Business Days' notice of any proposed repayment
pursuant to this Section 3.3 of Eurodollar Rate Loans, in each case, specifying
the proposed date of payment of Loans and the principal amount to be paid.  Each
such partial repayment of the Loans shall be in an amount of $10,000,000 or an
integral multiple of $1,000,000 in excess thereof, shall be accompanied by the
payment of accrued interest on the principal repaid to the date of payment, and
shall be applied, in the absence of instruction by the Borrower, first to the
principal of Alternative Base Rate Loans and then to the principal of Eurodollar
Rate Loans (in inverse order of the last days of their respective Interest
Periods).  Each partial repayment shall be allocated among the Banks, in
proportion, as nearly as practicable, to the respective unpaid principal amount
of each Bank's Loans, with adjustments to the extent practicable to equalize any
prior repayments not exactly in proportion.  Any amounts repaid under this
Section 3.3 may be reborrowed prior to the Maturity Date as provided in Section
2.6, subject to the conditions of Section 9.

4.      CERTAIN GENERAL PROVISIONS.
        -------------------------- 

        4.1  Application of Payments.
             ----------------------- 

             (a)  Except as otherwise provided in this Agreement, all
payments in respect of any Loan shall be applied first to accrued and unpaid
interest on such Loan and second to the outstanding principal of such Loan.

             (b)  If, at any time that a Default or Event of Default exists,
the Administrative Agent receives from the Borrower (or obtains funds for the
account of the Borrower, 

                                       25
<PAGE>
 
whether in connection with the enforcement of rights under the Loan Documents or
otherwise) less than the aggregate outstanding amount of all Obligations
hereunder, the Administrative Agent shall apply such amounts in the following
order of priority:

          First, to the payment of, or (as the case may be) the reimbursement of
          -----                                                                 
the Administrative Agent for or in respect of all costs, expenses,
disbursements, and losses that shall have been incurred or sustained by the
Administrative Agent in connection with the collection of such monies by the
Administrative Agent, for the exercise, protection, or enforcement by the
Administrative Agent of all or any of the rights, remedies, powers, and
privileges of the Administrative Agent under this Agreement or any of the other
Loan Documents, or in support of any provision of adequate indemnity to the
Administrative Agent against any taxes or Liens that by Government Mandate shall
have, or may have, priority over the rights of the Administrative Agent to such
monies;

          Second, to the satisfaction of any costs or expenses or other amounts
          ------                                                               
required to be paid by the Borrower under this Agreement not otherwise specified
in this Section 4.1(b);

          Third, to the satisfaction of any accrued and unpaid fees hereunder;
          -----                                                    

          Fourth, to the satisfaction of any accrued and unpaid interest on any
          ------                                                               
Loans, first to Swing Loans, second to other Loans;

          Fifth, to the satisfaction of any outstanding principal amount of any
          -----                                                                
Loans, first to Swing Loans, second to other Loans; and

          Sixth, the excess, if any, shall be returned to the Borrower or to
          -----                                                             
such other Persons as are entitled thereto.

      4.2 Funds for Payments.
          ------------------ 

          (a)  Payments to Administrative Agent. All payments of principal,
interest, facility fees and any other amounts due hereunder or under any of the
other Loan Documents shall be made to the Administrative Agent, for the
respective accounts of the Banks and the Administrative Agent, at the
Administrative Agent's Head Office or at such other location that the
Administrative Agent may from time to time designate, in each case in
immediately available funds.

          (b)  No Offset.  All payments by the Borrower hereunder and under any
               ---------                                             
of the other Loan Documents shall be made without setoff or counterclaim and
free and clear of and without deduction for any taxes, levies, imposts, duties,
charges, fees, deductions, withholdings, compulsory loans, restrictions, or
conditions of any nature now or hereafter imposed or levied by any Government
Authority unless the Borrower is compelled by Government Mandate to make such
deduction or withholding. If any such obligation is imposed upon the Borrower
with respect to any amount payable by it hereunder or under any of the other
Loan Documents (other than with respect to taxes on the income or profits of any
Bank or the Administrative Agent), the Borrower will pay to the Administrative
Agent, for the account of the Banks or (as the case may be) the Administrative
Agent, on the date on which such amount is due and payable hereunder or under
such other Loan Document, such additional amount in Dollars as shall be
necessary to enable the Banks or the Administrative 

                                       26
<PAGE>
 
Agent to receive the same net amount which the Banks or the Administrative Agent
would have received on such due date had no such obligation been imposed upon
the Borrower. The Borrower will deliver promptly to the Administrative Agent
certificates or other valid vouchers for all taxes or other charges deducted
from or paid with respect to payments made by the Borrower hereunder or under
such other Loan Document. If a refund is received (either in cash or by means of
a credit against future tax obligations) by the Administrative Agent or any Bank
in respect of an amount previously paid by the Borrower pursuant to the
immediately preceding sentence as determined solely by the Administrative Agent
or such Bank, such refund shall be promptly paid over to the Borrower; provided,
                                                                       --------
however, in no event shall the Borrower have any right to receive or review tax
- -------
returns of any Bank or the Administrative Agent. Any Bank that is not a United
States person (as such term is defined in Section 7701(a)(30) of the Code) for
U.S. Federal income tax purposes agrees to provide to the Borrower on or prior
to the Closing Date two original signed copies of Internal Revenue Service Form
4224 or Form 1001 certifying to such Bank's entitlement to an exemption from
United States withholding tax with respect to payments to be made under this
Agreement and under any Note and from time to time upon the reasonable written
request of the Borrower after the Closing Date, such Bank will provide to the
Borrower two original signed copies of Internal Revenue Service Form 4224 or
Form 1001 (or any successor forms) certifying to such Bank's entitlement to an
exemption from, or reduction in, United States withholding tax with respect to
payments to be made under this Agreement and under any Note.

      4.3 Computations.  All computations of interest with respect to
          ------------                                               
Alternative Base Rate Loans shall be based on a year of 365 days and paid for
the actual number of days elapsed.  All computations of interest with respect to
Eurodollar Rate Loans shall be based on a year of 360 days and paid for the
actual number of days elapsed.  Except as otherwise provided in the definition
of the term "Interest Period" with respect to Eurodollar Rate Loans, whenever a
payment hereunder or under any of the other Loan Documents becomes due on a day
that is not a Business Day, the due date for such payment shall be extended to
the next succeeding Business Day, and interest shall accrue during such
extension.

      4.4 Inability to Determine Eurodollar Rate.  In the event, prior to the
          --------------------------------------                             
commencement of any Interest Period relating to any Eurodollar Rate Loan, the
Administrative Agent shall determine that adequate and reasonable methods do not
exist for ascertaining the Eurodollar Rate that would otherwise determine the
rate of interest to be applicable to any Eurodollar Rate Loan during any
Interest Period, the Administrative Agent shall forthwith give notice of such
determination (which shall be conclusive and binding on the Borrower and the
Banks) to the Borrower and the Banks.  In such event (a) any Loan Request or
Conversion Request with respect to Eurodollar Rate Loans shall be automatically
withdrawn and shall be deemed a request for Alternative Base Rate Loans, (b)
each Eurodollar Rate Loan will automatically, on the last day of the then
current Interest Period relating thereto, become an Alternative Base Rate Loan,
and (c) the obligations of the Banks to make Eurodollar Rate Loans shall be
suspended until the Administrative Agent determines that the circumstances
giving rise to such suspension no longer exist, whereupon the Administrative
Agent shall so notify the Borrower and the Banks.

      4.5 Illegality.  Notwithstanding any other provisions herein, if any
          ----------                                                      
present or future Government Mandate shall make it unlawful for any Bank to make
or maintain Eurodollar Rate Loans, such Bank shall forthwith give notice of such
circumstances to the Borrower and the other Banks and thereupon (a) the
commitment of such Bank to make Eurodollar Rate Loans or convert 

                                       27
<PAGE>
 
Alternative Base Rate Loans to Eurodollar Rate Loans shall forthwith be
suspended, and (b) such Bank's Loans then outstanding as Eurodollar Rate Loans,
if any, shall be converted automatically to Alternative Base Rate Loans on the
last day of each then existing Interest Period applicable to such Eurodollar
Rate Loans or within such earlier period after the occurrence of such
circumstances as may be required by Government Mandate. The Borrower shall
promptly pay the Administrative Agent for the account of such Bank, upon demand
by such Bank, any additional amounts necessary to compensate such Bank for any
costs incurred by such Bank in making any conversion in accordance with this
Section 4.5 other than on the last day of an Interest Period, including any
interest or fees payable by such Bank to lenders of funds obtained by it in
order to make or maintain its Eurodollar Rate Loans hereunder.

      4.6 Additional Costs.  If any present or future applicable Government
          ----------------                                                 
Mandate (whether or not having the force of law), shall:

          (a) subject any Bank or the Administrative Agent to any tax,
levy, impost, duty, charge, fee, deduction, or withholding of any nature with
respect to this Agreement, the other Loan Documents, such Bank's Commitment, or
the Loans (other than taxes based upon or measured by the income or profits of
such Bank or the Administrative Agent), or

          (b) materially change the basis of taxation (except for changes
in taxes on income or profits) of payments to any Bank of the principal of or
the interest on any Loans or any other amounts payable to any Bank or the
Administrative Agent under this Agreement or the other Loan Documents, or

          (c) impose, increase, or render applicable (other than to the
extent specifically provided for elsewhere in this Agreement) any special
deposit, reserve, assessment, liquidity, capital adequacy, or other similar
requirements (whether or not having the force of law) against assets held by, or
deposits in or for the account of, or loans by, or commitments of an office of
any Bank, or

          (d) impose on any Bank or the Administrative Agent any other
conditions or requirements with respect to this Agreement, the other Loan
Documents, the Loans, such Bank's Commitment, or any class of loans or
commitments of which any of the Loans or such Bank's Commitment forms a part,
and the result of any of the foregoing is:

               (i)   to increase by an amount deemed by such Bank to be material
to the cost to any Bank of making, funding, issuing, renewing, extending, or
maintaining any of the Loans or such Bank's Commitment, or

               (ii)  to reduce, by an amount deemed by such Bank or the
Administrative Agent, as the case may be, to be material, the amount of
principal, interest, or other amount payable to such Bank or the Administrative
Agent hereunder on account of such Bank's Commitment or any of the Loans, or

               (iii) to require such Bank or the Administrative Agent to make
any payment that, but for such conditions or requirements described in clauses
(a) through (d), would not be payable hereunder, or forego any interest or other
sum that, but for such conditions or 

                                       28
<PAGE>
 
requirements described in clauses (a) through (d), would be payable to such Bank
or the Administrative Agent hereunder, in any case the amount of which payment
or foregone interest or other sum is deemed by such Bank or the Administrative
Agent, as the case may be, to be material and is calculated by reference to the
gross amount of any sum receivable or deemed received by such Bank or the
Administrative Agent from the Borrower hereunder, then, and in each such case,
(x) the Borrower will, upon demand made by such Bank or (as the case may be) the
Administrative Agent at any time and from time to time (such demand to be made
in any case not later than the first to occur of (A) the date one hundred and
eighty (180) days after such event described in clause (i), (ii), or (iii)
giving rise to such demand, and (B) the date ninety (90) days after both the
payment in full of all outstanding Loans and termination of the Commitments) and
as often as the occasion therefor may arise, pay to such Bank or the
Administrative Agent such additional amounts as will be sufficient to compensate
such Bank or the Administrative Agent for such additional cost, reduction,
payment, foregone interest, or other sum, (y) the Borrower shall be entitled,
upon notice to the Administrative Agent and each Bank given within ninety (90)
days of any demand by a Bank under clause (x), to repay in cash in full all, but
not less than all, of the Loans of such Bank, together with all accrued and
unpaid interest on such Loans and any other amounts owing to such Bank under the
Loan Documents and terminate (in full and not in part) such Bank's Commitment,
and, (z) in the event the Borrower elects to repay the Loans of any Bank under
clause (y), each other Bank shall be entitled, by notice to the Administrative
Agent and the Borrower given within forty-five (45) days after receipt of the
notice referred to in clause (y), to require the Borrower to repay in cash in
full, within forty-five (45) days of such notice under this clause (z), all, but
not less than all, of the Loans of such other Bank, together with all accrued
and unpaid interest on such Loans and any other amounts owing to such other Bank
under the Loan Documents. Subject to the terms specified above in this Section
4.6, the obligations of the Borrower under this Section 4.6 shall survive
repayment of the Loans and termination of the Commitments.

      4.7 Capital Adequacy.  If after the date hereof any Bank or the
          ----------------                                           
Administrative Agent determines that (a) the adoption of or change in any
Government Mandate (whether or not having the force of law) regarding capital
requirements for banks or bank holding companies or any change in the
interpretation or application thereof by any applicable Government Authority
with appropriate jurisdiction, or (b) compliance by such Bank or the
Administrative Agent, or any corporation controlling such Bank or the
Administrative Agent, with any Government Mandate (whether or not having the
force of law) has the effect of reducing the return on such Bank's or the
Administrative Agent's commitment with respect to any Loans to a level below
that which such Bank or the Administrative Agent could have achieved but for
such adoption, change, or compliance (taking into consideration such Bank's or
the Administrative Agent's then existing policies with respect to capital
adequacy and assuming full utilization of such Entity's capital) by any amount
reasonably deemed by such Bank or (as the case may be) the Administrative Agent
to be material, then such Bank or the Administrative Agent may notify the
Borrower of such fact.  To the extent that the amount of such reduction in the
return on capital is not reflected in the Alternative Base Rate, (x) the
Borrower shall pay such Bank or (as the case may be) the Administrative Agent
for the amount of such reduction in the return on capital as and when such
reduction is determined upon presentation by such Bank or (as the case may be)
the Administrative Agent of a certificate in accordance with Section 4.8 hereof
(but in any case not later than the first to occur of (I) the date one hundred
and eighty (180) days after such adoption, change, or compliance causing such
reduction, and (II) as to adoptions of or changes in Government Mandates
occurring prior to the repayment of the Loans and the termination of the

                                       29
<PAGE>
 
Commitment the date ninety (90) days after both the payment in full of all
outstanding Loans and termination of the Commitments), (y) the Borrower shall be
entitled, upon notice to the Administrative Agent and each Bank given within
ninety (90) days of any notice by such Bank under the next preceding sentence,
to repay in cash in full all, but not less than all, of the Loans of such Bank,
together with all accrued and unpaid interest on such Loans and any other
amounts owing to such Bank under the Loan Documents and terminate (in full and
not in part) such Bank's Commitment, and, (z) in the event the Borrower elects
to repay the Loans of any Bank under clause (y), each other Bank shall be
entitled, by notice to the Administrative Agent and the Borrower given within
forty-five (45) days after receipt of the notice referred to in clause (y), to
require the Borrower to repay in cash in full, within forty-five (45) days of
the notice under this clause (z), all, but not less than all, of the Loans of
such other Bank, together with all accrued and unpaid interest on such Loans and
any other amounts owing to such other Bank under the Loan Documents.  Each Bank
shall allocate such cost increases among its customers in good faith and on an
equitable basis. Each Bank will use reasonable efforts (subject to overall
policy considerations of such Bank) to avoid or mitigate any increased cost or
obligation to prepay arising under this Section to the greatest extent
practicable (including transferring its Loans to another lending office or
affiliate of the Bank) unless, in the opinion of the Bank, such efforts would be
likely to result in the Bank (or its lending office or affiliate) suffering a
material economic, legal or regulatory disadvantage, and provided, further, that
nothing in this sentence shall affect or postpone the Borrower's obligations
hereunder, or any of the Bank's rights hereunder. Subject to the terms specified
above in this Section 4.7, the obligations of the Borrower under this Section
4.7 shall survive repayment of the Loans and termination of the Commitments.

      4.8 Certificate.  A certificate setting forth any additional amounts
          -----------                                                     
payable pursuant to Section 4.6 or Section 4.7 and a brief explanation of such
amounts which are due and in reasonable detail the basis of the calculation and
allocation thereof, submitted by any Bank or the Administrative Agent to the
Borrower, shall be conclusive evidence, absent manifest error, that such amounts
are due and owing.

      4.9 Indemnity.  The Borrower shall indemnify and hold harmless each
          ---------                                                      
Bank from and against any loss, cost, or expense (excluding loss of anticipated
profits) that such Bank may sustain or incur as a consequence of (a) default by
the Borrower in payment of the principal amount of or any interest on any
Eurodollar Rate Loans as and when due and payable, including any such loss or
expense arising from interest or fees payable by such Bank to lenders of funds
obtained by it in order to maintain its Eurodollar Rate Loans, (b) default by
the Borrower in making a borrowing or conversion after the Borrower has given
(or is deemed to have given) a Loan Request or a Conversion Request; or (c)
except as otherwise expressly provided in Section 3.3, the making of any payment
of a Eurodollar Rate Loan or the making of any conversion of any such Loan to an
Alternative Base Rate Loan on a day that is not the last day of the applicable
Interest Period with respect thereto, including interest or fees payable by such
Bank to lenders of funds obtained by it in order to maintain any such Loans.
The obligations of the Borrower under this Section 4.9 shall survive repayment
of the Loans and termination of the Commitments.

      4.10 Interest After Event of Default.  All amounts outstanding under
           -------------------------------                                
the Loan Documents that are not paid when due, including all overdue principal
and (to the extent permitted by applicable Government Mandate) interest and all
other overdue amounts (after giving effect to any applicable grace period),
shall to the extent permitted by applicable Government Mandate bear interest
until such amount shall be paid in full (after as well as before judgment) at a
rate per annum equal to 

                                       30
<PAGE>
 
two percent (2%) above the Alternative Base Rate. Any interest accruing under
this section on overdue principal or interest shall be due and payable upon
demand.

      4.11 Special Banks.  Unless the Majority Banks seek indemnification,
           -------------                                                  
payment, or reimbursement under, or invoke the provisions of, Section 4.5, 4.6
or 4.7, if the Borrower is obligated to pay to the Administrative Agent or any
Bank any amount under said Sections, the Borrower may, at its option, so long as
no Default or Event of Default then exists, (x) subject to Section 4.9 hereof,
repay the outstanding Loans in favor of such Bank, which repayment shall be
allocated solely to Loans in favor of such Bank, and in the event of such
repayment, such Bank shall cease to be a Bank under this Agreement and the Total
Commitment hereunder shall be reduced by the amount of the Commitment of such
Bank (and the Commitment Percentages of the remaining Banks shall be
recalculated accordingly), or (y)  replace such Bank with a new Bank reasonably
acceptable to the Administrative Agent, and such Bank hereby agrees to be so
replaced subject to the following:

           (a) The obligations of the Borrower hereunder to the Bank to be
replaced (including such increased or additional costs incurred from the date of
notice to the Borrower of such increase or additional costs through the date
such Bank is replaced hereunder) shall be paid in full to such Bank concurrently
with such replacement;

           (b) The replacement Bank shall be a Bank that is not subject to
the increased costs arising under such Sections which may have effectuated the
Borrower's election to replace any Bank hereunder;

           (c) Each such replacement Bank shall execute and deliver to the
Administrative Agent such documentation reasonably satisfactory to the
Administrative Agent pursuant to which such Bank is to be come a party hereto
with a Commitment equal to that of the Bank being replaced and shall make a Loan
or Loans in the aggregate principal amount equal to the aggregate outstanding
principal amount of the Loan or Loans of the Bank being replaced;

           (d) Upon such execution of such documents referred to in clause
(c) and repayment of the amounts referred to in clause (a), the replacement Bank
shall be a Bank with a Commitment as specified hereinabove and the Bank being
replaced shall cease to be a Bank hereunder, except with respect to
indemnification provisions under this Agreement, which shall survive as to such
replaced Bank; and

           (e) The Administrative Agent shall reasonably cooperate in
effectuating the replacement of any Bank hereunder, but at no time shall the
Administrative Agent be obligated to initiate any such replacement; and

           (f) Any Bank replaced hereunder shall be replaced at the
Borrower's sole cost and expense and at no cost or expense to the Administrative
Agent.

                (b) Authorization.  The execution, delivery, and performance of
                    -------------                                              
this Agreement and the other Loan Documents to which the Borrower, any of its

Entity, and (v) do not violate, conflict with, constitute a default or event of
default under, or result in any rights to accelerate or modify any obligations
under any Contract to which any such Entity is party or subject, or to which any
of its respective assets are subject, except where such violation, conflict,
default, event of default or right to accelerate or modify any obligations under
any Contract would not be likely to have a Material Effect.

Agreement and the other Loan Documents to which the Borrower, any of its
Subsidiaries, or PGP is or is to become a party will result in valid and legally

                       ---------------
Holdings has agreed, committed, or otherwise obligated itself to authorize or
issue any Equity Securities. All of the outstanding Equity Securities of the
Borrower are validly issued, fully paid, and non-assessable.

           5.2 Governmental Approvals.  The execution, delivery, and performance
               ----------------------                                           
by the Borrower, its Subsidiaries, and PGP of this Agreement and the other Loan
Documents to which the Borrower, any of its Subsidiaries, or PGP is or is to

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

           5.3 Liens; Leases.  The assets of the Borrower are subject to no
               -------------
Liens except Permitted Liens. Each of the Borrower and its Subsidiaries enjoys
quiet possession under all leases relating to Real Estate or personal property

possession or be Fully Effective would not have a Material Effect.

           5.4 Financial Statements.  There has been furnished to the
               --------------------                                  
Administrative Agent and each of the Banks (a) a consolidated balance sheet of
the Borrower as at December 31, 1997, December 31, 1996 and December 31, 1995,
and a consolidated statement of income and cash flow of the Borrower for the
fiscal year then ended, certified by the Borrower's independent certified public
accountants, and (b) unaudited consolidated balance sheets of the Borrower as at
March 31, 1997, June 30, 1997, and September 30, 1997 and consolidated
statements of income and of cash flow of the Borrower for the respective fiscal
periods then ended and as set forth in the Borrower's Quarterly Reports on Form
10-Q for such fiscal quarters.  With respect to the financial statements
prepared in accordance with clause (a) above, such balance sheet and statement
of income have been prepared in accordance with GAAP, and present fairly in all
material respects the financial position of the Borrower and its Subsidiaries as
at the close of business on the respective dates thereof and the results of
operations of the Borrower and its Subsidiaries for the fiscal periods then
ended; or, in the case of the financial statements referred to in clause (b),
have been prepared in accordance with Rule 10-01 of Regulation S-X of the
Securities and Exchange Commission, and contain all adjustments necessary for a
fair presentation of (i) the results of operations of the Borrower for the
periods covered thereby, (ii) the financial position of the Borrower at the date
thereof, and (iii) the cash flows of the Borrower for periods covered thereby
(subject to year-end adjustments).  There are no contingent liabilities of the
Borrower or its Subsidiaries as of such dates involving material amounts, known
to the executive management of the Borrower that (x) should have been disclosed
in said balance sheets or the related notes thereto in accordance with GAAP and
the rules and regulations of the Securities and Exchange Commission, and (y)
were not so disclosed.

           5.5 No Material Changes.  Except as set forth on Schedule 5.5, no
               -------------------                          ------------    
change in the Business of the Borrower and its Subsidiaries, taken as a whole,
has occurred since December 31, 1996 that has resulted in a Material Effect.

           5.6 Permits.  The Borrower and its Subsidiaries have all Permits
               -------                                                     
necessary or appropriate for them to conduct their Business, except where the
failure to have such Permits would 

                                       33
<PAGE>
 
not be likely to have a Material Effect. All of such Permits are in full force
and effect. Without limiting the foregoing, the Borrower is duly registered as
an "investment adviser" under the Investment Advisers Act of 1940 and under the
applicable laws of each state in which such registration is required in
connection with the investment advisory business of the Borrower and in which
the failure to obtain such registration would be likely to have a Material
Effect; PIMCO Funds Distributors LLC is duly registered as a "broker/dealer"
under the Securities Exchange Act of 1934 and under the securities or blue sky
laws of each state in which such registration is required in connection with the
business conducted by PIMCO Funds Distributors LLC and where a failure to obtain
such registration would be likely to have a Material Effect, and is a member in
good standing of the National Association of Securities Dealers, Inc.; no
Proceeding is pending or threatened with respect to the suspension, revocation,
or termination of any such registration or membership, and the termination or
withdrawal of any such registration or membership is not contemplated by the
Borrower or PIMCO Funds Distributors LLC except, only with respect to
registrations by the Borrower and PIMCO Funds Distributors LLC required under
state law, as would not be likely to have a Material Effect.

           5.7 Litigation.  Except as disclosed on Schedule 5.7 hereto as of
               ----------                          ------------       
the Closing Date, or as disclosed to the Administrative Agent and the Banks in
writing with respect to any subsequent date, there is no Proceeding of any kind
pending against the Borrower, any of its Subsidiaries, or PGP with an amount in
controversy exceeding the Material Amount. None of such Proceedings (a) is
reasonably likely to, either in any case or in the aggregate, have a Material
Effect, or (b) questions the validity of this Agreement or any of the other Loan
Documents, or any action taken or to be taken pursuant hereto or thereto.

           5.8 Material Contracts.  Except as would not be likely to have a
               ------------------                                          
Material Effect, each Contract to which any of the Borrower and its Subsidiaries

(including investment advisory contracts and investment company distribution
plans) (a) is Fully Effective, (b) is not subject to any default or event of
default with respect to the Borrower, any of its Subsidiaries or, to the best
knowledge of the executive management of the Borrower, any other party, (c) is
not subject to any notice of termination given or received by the Borrower or
any of its Subsidiaries, and (d) is, to the best knowledge of the executive
management of the Borrower, the legal, valid, and binding obligation of each
party thereto other than the Borrower and its Subsidiaries enforceable against
such parties according to its terms.

           5.9 Compliance with Other Instruments, Laws.  None of the Borrower,
               ---------------------------------------
its Subsidiaries, or PGP is in violation of or default under (a) any provision
of its certificate of incorporation or by-laws, or its certificate of limited
partnership or agreement of limited or general partnership, as the case may be,
(b) except for the Note Agreement, any Contract to which it is or may be subject
or by which it or any of its properties are or may be bound, or (c) any
Government Mandate, including Government Mandates relating to occupational
safety and employment matters, except (with respect to subsections (b) and (c)),
in any case, where such violation or default would not be likely to have a
Material Effect.

           5.10  Tax Status.  The Borrower and its Subsidiaries (a) have made or
                 ----------                                                     
filed all federal and state income and all other tax returns, reports, and
declarations required by any Government Authority to which any of them is
subject, except where the failure to make or file the same would not be likely
to have a Material Effect, (b) have paid all taxes and other governmental
assessments and 

                                       34
<PAGE>
 
charges due, except those being contested in good faith and by appropriate
Proceedings or those where a failure to pay is not reasonably likely to have a
Material Effect, and (c) have set aside on their books provisions reasonably
adequate for the payment of all taxes for periods subsequent to the periods to
which such returns, reports, or declarations apply. There are no unpaid taxes in
any material amount claimed to be due from the Borrower or any of its
Subsidiaries by any Government Authority, and the executive management of the
Borrower knows of no basis for any such claim.

           5.11 No Event of Default.  No Default has occurred and is continuing.
                -------------------                                 

           5.12 Holding Company and Investment Company Acts.  Neither the
                -------------------------------------------              
Borrower nor any of its Subsidiaries is a "holding company", or a "subsidiary
company" of a "holding company", as such terms are defined in the Public Utility
Holding Company Act of 1935.  Neither the Borrower nor any of its Subsidiaries
is an "investment company", as such term is defined in the 1940 Act, required to
be registered in accordance with such Act.

           5.13 Insurance.  The Borrower and its Subsidiaries maintain
                ---------                                             
insurance with financially sound and reputable insurers in such coverage
amounts, against such risks, with such deductibles and upon such other terms, or
are self-insured in respect of such risks (with appropriate reserves to the
extent required by GAAP), as is reasonable and customary for firms engaged in
businesses similar to those of the Borrower and its Subsidiaries.  All policies
of insurance maintained by the Borrower or its Subsidiaries are Fully Effective.
All premiums due on such policies have been paid or accrued on the books of the
Borrower or its Subsidiaries, as appropriate.

           5.14 Certain Transactions.  Except in connection with (a) the PGP
                --------------------                                        
Refinancing, (b) transactions occurring in the ordinary course of business, (c)
transactions between the Borrower and Holdings authorized pursuant to the
Amended and Restated Operating Agreement dated as of January 1, 1998 by and
between Holdings and the Borrower, so long as PGP shall remain the sole general
partner of Holdings, (d) transactions with a Public General Partner that was
formerly a limited partner of the Borrower, and (e) transactions occurring on
fair and reasonable terms no less favorable to the Borrower and its Subsidiaries
taken as a whole than would be obtained in comparable arms' length transactions
with Persons that are not Affiliates of the Borrower or its Subsidiaries, none
of the officers, directors, partners, or employees of the Borrower or any of its
Subsidiaries, or, to the knowledge of the executive management of the Borrower,
any Entity (other than a Subsidiary) in which any such officer, director,
partner, or employee has a substantial interest or is an officer, director,
trustee, or partner, is at present a party to any transaction with the Borrower
or any of its Subsidiaries (other than for or in connection with services as
officers, directors, partners, or employees, as the case may be), including any
Contract providing for the furnishing of services to or by, providing for rental
of real or personal property to or from, or otherwise requiring payments to or
from any such officer, director, partner, employee, or Entity.

           5.15  Employee Benefit Plans.
                 ---------------------- 

                 (a)    In General.  Set forth on Schedule 5.15 is a
                        ----------                -------------     
list of each Employee Benefit Plan and Multiemployer Plan of the Borrower and
its Subsidiaries as of the Closing Date.  After the Closing Date, any additional
Employee Benefit or Multiemployer Plan shall be disclosed to the Administrative
Agent in writing.  Each Employee Benefit Plan has been maintained and operated
in compliance in all material respects with the provisions of ERISA and, to the
extent applicable, the 

                                       35
<PAGE>
 
Code, including the provisions thereunder respecting prohibited transactions,
except where the failure to so comply would not be likely to have a Material
Effect.

                 (b)    Terminability of Welfare Plans.  Under each Employee
                        ------------------------------                      
Benefit Plan which is an employee welfare benefit plan within the meaning of
(S)3(1) or (S)3(2)(B) of ERISA, no benefits are due unless the event giving rise
to the benefit entitlement occurs prior to plan termination (except as required
by Title I, Part 6 of ERISA).  The Borrower or an ERISA Affiliate, as
appropriate, may terminate each such Plan at any time (or at any time subsequent
to the expiration of any applicable bargaining agreement) in the discretion of
the Borrower or such ERISA Affiliate without liability to any Person, except as
would not be likely to have a Material Effect.

                 (c)    Guaranteed Pension Plans.  Each contribution required to
                        ------------------------
be made to a Guaranteed Pension Plan, whether required to be made to avoid the
incurrence of an accumulated funding deficiency, the notice or lien provisions
of (S)302(f) of ERISA, or otherwise, has been timely made. No waiver of an
accumulated funding deficiency or extension of amortization periods has been
received with respect to any Guaranteed Pension Plan. No liability to the PBGC
(other than required insurance premiums, all of which have been paid) has been
incurred by the Borrower or any ERISA Affiliate with respect to any Guaranteed
Pension Plan and there has not been any ERISA Reportable Event, or any other
event or condition which presents a material risk of termination of any
Guaranteed Pension Plan by the PBGC. Based on the latest valuation of each
Guaranteed Pension Plan (which in each case occurred within fifteen (15) months
of the date of this representation), and on the actuarial methods and
assumptions employed for that valuation, the aggregate benefit liabilities of
all such Guaranteed Pension Plans within the meaning of (S)4001 of ERISA did not
exceed the aggregate value of the assets of all such Guaranteed Pension Plans by
more than $10,000,000, disregarding for this purpose the benefit liabilities and
assets of any Guaranteed Pension Plan with assets in excess of benefit
liabilities.

                 (d)    Multiemployer Plans.  Neither the Borrower nor any ERISA
                        -------------------                                     
Affiliate has incurred any material liability (including secondary liability) to
any Multiemployer Plan as a result of a complete or partial withdrawal from such
Multiemployer Plan under (S)4201 of ERISA or as a result of a sale of assets
described in (S)4204 of ERISA.  Neither the Borrower nor any ERISA Affiliate has
been notified that any Multiemployer Plan is in reorganization or insolvent
under and within the meaning of (S)4241 or (S)4245 of ERISA or that any
Multiemployer Plan intends to terminate or has been terminated under (S)4041A
of ERISA.

           5.16  Use of Proceeds; Regulations U and X.
                 ------------------------------------ 

                 (a)  The proceeds of the Loans shall be used by the Borrower to
refinance certain Indebtedness, for working capital and for general corporate
purposes and may be used to repay the Private Placement Notes.

                 (b)  No portion of any Loan is to be used for the purpose of
purchasing or carrying any "margin security" or "margin stock" as such terms are
used in Regulations U and X of the Board of Governors of the Federal Reserve
System, 12 C.F.R. Parts 221 and 224.

environmental, safety, or public health matters, including the Resource
Conservation and Recovery Act ("RCRA"), the Comprehensive Environmental

Material Effect;

                 (b)  neither the Borrower nor any of its Subsidiaries has
received notice from any third party, including any Government Authority, (i)
that any one of them has been identified by the United States Environmental
Protection Agency ("EPA") as a potentially responsible party under CERCLA with

respect to a site listed on the National Priorities List, 40 C.F.R. Part 300

(S)9601(5), any hazardous substances as defined by 42 U.S.C. (S)9601(14), any
pollutant or contaminant as defined by 42 U.S.C. (S)9601(33) and any toxic

generated, transported, or disposed of has been found at any site at which a
Government Authority or other third party has conducted, or has ordered that
other parties conduct, a remedial investigation, removal, or other response

out of any third party's incurrence of costs, expenses, losses, or damages of
any kind whatsoever in connection with the release of Hazardous Substances; and

                 (c)  except as would not be likely to have a Material Effect:

                      (i)   no portion of the Real Estate has been used for the
                 handling, processing, storage, or disposal of Hazardous
                 Substances except in accordance with applicable Environmental
                 Laws;

                      (ii)  no underground tank or other underground storage
                 receptacle for Hazardous Substances is located on any portion
                 of the Real Estate;

                      (iii) in the course of any activities conducted by any of
                 the Borrower, its Subsidiaries, PGP, and operators of any Real
                 Estate, no Hazardous Substances have been generated or are
                 being used on the Real Estate except in accordance with

fact to the Administrative Agent and the Banks at least forty (40) days prior to
any proposed Change of Control Date, (i) except to the extent the Borrower may
be prohibited by U.S. securities laws from giving such a notice, in which case
the Borrower shall do so as soon as may be legally permissible and (ii) except
to the extent the Borrower may be prohibited by a written confidentiality
covenant, in which case the Borrower shall do so as soon as it is contractually
permitted and in any event not later than forty-eight (48) hours prior to such
Change of Control.  Any Control Change Notice shall describe the principal facts
and circumstances of such Change of Control known to the Borrower in reasonable
detail (including the Change of Control Date or, if the Borrower does not have
knowledge of the Change of Control Date, the Borrower's best estimate of such
Change of Control Date).  In the event the Borrower shall not have designated
the Change of Control Date in its Control Change Notice, the Borrower shall keep
the Administrative Agent and the Banks informed as to any changes in the
estimated Change of Control Date and shall provide written notice to the
Administrative Agent and the Banks specifying the Change of Control Date

Amount or (B) the Administrative Agent shall be advised by its legal counsel in
writing that there is a reasonable possibility of such a seizure, attachment, or
forfeiture under applicable Government Mandates, or (ii) be found guilty of, or
shall plead guilty, no contest, or nolo contendere to, any federal or state
                                   ---- ----------                         
crime, a punishment for which could include a fine, penalty, or forfeiture of
any assets of the Borrower, PGP, or such Subsidiary.

                Upon the occurrence of an Event of Default, the Administrative
Agent, upon the request of the Majority Banks, shall by notice in writing to the

rescinded by the Majority Banks if the Events of Default leading to such
declaration are waived in writing by the Majority Banks.

     10.2  Termination of Commitments.  If any one or more of the Events of
           --------------------------                                      
Default specified in Section 10.1(h) or Section 10.1(i) shall occur, any unused
portion of the Total Commitments hereunder shall forthwith terminate and each of
the Banks shall be relieved of all obligations to make Loans to the Borrower.
If any other Event of Default shall have occurred, or if on any Drawdown Date
the conditions precedent to the making of the Loans to be made on such Drawdown
Date are not satisfied, the Administrative Agent may with the consent of the
Majority Banks and, upon the request of the Majority Banks, shall, by notice to
the Borrower, terminate the unused portion of the Total Commitment hereunder,
and upon such notice being given such unused portion of the Total Commitment
hereunder shall terminate immediately and each of the Banks shall be relieved of
all further obligations to make Loans.  If any such notice is given to the
Borrower, the Administrative Agent will forthwith furnish a copy thereof to each

                                       54

           -------- 

           (a)  In case any one or more of the Events of Default shall have
occurred, and whether or not the Administrative Agent shall have accelerated the
maturity of the Loans pursuant to Section 10.1, each Bank, if owed any amount
with respect to the Loans, may with the consent of the Majority Banks but not
otherwise, proceed to protect and enforce its rights by any appropriate
Proceeding, whether for the specific performance of any covenant or agreement
contained in this Agreement and the other Loan Documents or any instrument
pursuant to which the Obligations to such Bank are evidenced, including as
permitted by applicable Government Mandate the obtaining of the ex parte
appointment of a receiver, and, if such amount shall have become due, by
declaration or otherwise, proceed to enforce the payment thereof or any other
legal or equitable right of such Bank.

           (b)  No remedy herein conferred upon any Bank or the Administrative
Agent or the holder of any Note is intended to be exclusive of any other remedy,
and each and every remedy shall be cumulative and shall be in addition to every
other remedy given hereunder or now or hereafter existing at law or in equity or
by any Government Mandate.

11.  SETOFF.
     ------ 

     Regardless of the adequacy of any collateral, during the continuance of any
Event of Default, any deposits or other sums credited by or due from any of the
Banks to the Borrower and any securities or other property of the Borrower in
the possession of such Bank may be applied to or set off by such Bank against
the payment of Obligations and any and all other liabilities, direct, or
indirect, absolute or contingent, due or to become due, now existing or
hereafter arising, of the Borrower to such Bank. Each of the Banks agrees with
each other Bank that (a) if an amount to be set off is to be applied to
Indebtedness of the Borrower to such Bank, other than Indebtedness evidenced by
the Notes held by such Bank, such amount shall be applied ratably to such other
Indebtedness and to the Indebtedness evidenced by all such Notes held by such
Bank, and (b) if such Bank shall receive from the Borrower, whether by voluntary
payment, exercise of the right of setoff, counterclaim, cross action,
enforcement of the claim evidenced by the Notes held by such Bank by Proceedings
against the Borrower, by proof thereof in bankruptcy, reorganization,
liquidation, receivership or similar Proceedings, or otherwise, and shall retain
and apply to the payment of the Note or Notes held by such Bank any amount in
excess of its ratable portion of the payments received by all of the Banks with
respect to the Notes held by all of the Banks (exclusive of payments to be made
for the account of less than all of the Banks as provided in Sections 4.6, 4.7,
4.8, and 4.9), such Bank will make such disposition and arrangements with the
other Banks with respect to such excess, either by way of distribution, pro
                                                                        ---
tanto assignment of claims, subrogation, or otherwise as shall result in each
- -----                                                                        
Bank receiving in respect of the Notes held by it its proportionate payment as
contemplated by this Agreement; provided that if all or any part of such excess
                                --------                                       
payment is thereafter recovered from such Bank, such disposition and
arrangements shall be rescinded and the amount restored to the extent of such
recovery, but without interest.

12.  THE ADMINISTRATIVE AGENT AND THE DOCUMENTATION AGENT.
     ---------------------------------------------------- 

     12.1  Authorization.  The Administrative Agent and the Documentation Agent
           -------------                                                 
are authorized to take such action on behalf of each of the Banks and to
exercise all such powers as are hereunder and under any of the other Loan
Documents and any related documents delegated to the Administrative Agent or the
Documentation Agent, respectively, together with such powers as are reasonably
incident thereto, provided that no duties or responsibilities not expressly
                  --------                                                 
assumed herein or therein shall be implied to have been assumed by the
Administrative Agent or the Documentation Agent.  The relationship between the
Administrative Agent and the Banks and between the Documentation Agent and the
Banks is and shall be that of agent and principal only, and nothing contained in
this Agreement or any of the other Loan Documents shall be construed to
constitute the Administrative Agent or the Documentation Agent as a trustee for
any Bank.

     12.2  Employees and Administrative Agents.  Each of the Administrative
           -----------------------------------                             
Agent and the Documentation Agent may exercise its powers and execute its duties
by or through employees or agents and shall be entitled to take, and to rely on,
advice of legal counsel concerning all matters pertaining to its rights and
duties under this Agreement and the other Loan Documents.  Each of the
Administrative Agent and the Documentation Agent may utilize the services of
such Persons as it in its sole discretion may reasonably determine.

     12.3  No Liability.  Neither the Administrative Agent, the Documentation
           ------------                                                      
Agent nor any of their respective shareholders, directors, officers or employees
nor any other Person assisting them in their duties nor any agent or employee
thereof, shall be liable for any waiver, consent or approval given or any action
taken, or omitted to be taken, in good faith by it or them hereunder or under
any of the other Loan Documents, or in connection herewith or therewith, or be
responsible for the consequences of any oversight or error of judgment
whatsoever, except that the Administrative Agent, the Documentation Agent or
such other Person, as the case may be, may be liable for losses due to its
willful misconduct or gross negligence.

     12.4  No Representations.  Neither the Administrative Agent nor the
           ------------------                                           
Documentation Agent shall be responsible for the execution (other than on its
own behalf) or validity or enforceability of this Agreement, the Notes, any of
the other Loan Documents or any instrument at any time constituting, or intended
to constitute, collateral security for the Notes, or for the value of any such
collateral security or for the validity, enforceability, or collectability of
any such amounts owing with respect to the Notes, or for any recitals or
statements, warranties, or representations made herein or in any of the other
Loan Documents or in any certificate or instrument hereafter furnished to it by
or on behalf of the Borrower, or be bound to ascertain or inquire as to the
performance or observance of any of the terms, conditions, covenants, or
agreements herein or in any instrument at any time constituting, or intended to
constitute, collateral security for the Notes or to inspect any of the
properties, books, or records of the Borrower or any of its Subsidiaries.
Neither the Administrative Agent nor the Documentation Agent shall be bound to
ascertain whether any notice, consent, waiver, or request delivered to it by the
Borrower or any holder of any of the Notes shall have been duly authorized or is
true, accurate, and complete.  Neither the Administrative Agent nor the
Documentation Agent has made nor does it now make any representations or
warranties, express or implied, nor does it assume any liability to the Banks,
with respect to the credit worthiness or financial conditions of the Borrower or
any of its Subsidiaries.  Each Bank acknowledges that it has, independently and
without reliance upon the Administrative Agent, the Documentation Agent or any

                                       56
<PAGE>
 
other Bank, and based upon such information and documents as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement.

     12.5  Payments.
           -------- 

           (a)  Payments to Administrative Agent.  A payment by the Borrower to
                --------------------------------                               
the Administrative Agent hereunder or under any of the other Loan Documents for
the account of any Bank shall constitute a payment to such Bank.  The
Administrative Agent shall promptly distribute to each Bank such Bank's pro rata
                                                                        --------
share of payments received by the Administrative Agent for the account of the
Banks except as otherwise expressly provided herein or in any of the other Loan
Documents.

           (b)  Distribution by Administrative Agent.  If in the reasonable
                ------------------------------------                       
opinion of the Administrative Agent the distribution of any amount received by
it in such capacity hereunder, under the Notes, or under any of the other Loan
Documents might involve it in liability, it may refrain from making distribution
until its right to make the same shall have been adjudicated by a court of
competent jurisdiction.  If any Government Authority shall adjudge that any
amount received and distributed by the Administrative Agent is to be repaid,
each Person to whom any such distribution shall have been made shall either
repay to the Administrative Agent its proportionate share of the amount so
adjudged to be repaid or shall pay over the same in such manner and to such
Persons as shall be determined by such Government Authority.

     12.6  Holders of Notes.  Subject to Section 16, the Administrative Agent
           ----------------                                                  
may deem and treat the payee of any Note as the absolute owner thereof for all
purposes hereof until it shall have been furnished in writing with a different
name by such payee or by a subsequent holder, assignee, or transferee.

     12.7  Indemnity.  The Banks ratably shall indemnify and hold harmless the
           ---------                                                          
Administrative Agent and the Documentation Agent from and against any and all
Proceedings (whether groundless or otherwise), losses, damages, costs, expenses
(including any expenses for which the Administrative Agent has not been
reimbursed by the Borrower as required by Section 13), and liabilities of every
nature and character arising out of or related to this Agreement, the Notes, any
of the other Loan Documents, or the transactions contemplated or evidenced
hereby or thereby, or the Administrative Agent's or Documentation Agent's
actions taken hereunder or thereunder, except to the extent that any of the same
shall be directly caused by the Administrative Agent's or Documentation Agent's
willful misconduct or gross negligence.

     12.8  Administrative Agent and Documentation Agent as Bank.  In its
           ----------------------------------------------------         
individual capacity, each of NationsBank, N.A. or Deutsche Bank AG, New York
Branch shall have the same obligations and the same rights, powers, and
privileges in respect to its Commitment and the Loans made by it, and as the
holder of any of the Notes, as it would have were it not also the Administrative
Agent or Documentation Agent, as the case may be.

     12.9  Resignation.  The Administrative Agent or Documentation Agent may
           -----------                                                      
resign at any time by giving sixty (60) days' prior written notice thereof to
the Banks and the Borrower.  Any Administrative Agent or Documentation Agent
resigning from this Agreement shall also resign from the Short-Term Credit
Agreement.  Upon any such resignation, the Majority Banks shall have the 

                                       57
<PAGE>
 
right to appoint a successor Administrative Agent or Documentation Agent. Unless
an Event of Default shall have occurred and be continuing, such successor
Administrative Agent or Documentation Agent shall be reasonably acceptable to
the Borrower. If no successor Administrative Agent or Documentation Agent shall
have been so appointed by the Majority Banks and shall have accepted such
appointment within thirty (30) days after the retiring Administrative Agent's or
Documentation Agent's giving of notice of resignation, then the retiring
Administrative Agent or Documentation Agent may, on behalf of the Banks, appoint
a successor Administrative Agent or Documentation Agent, which shall be a
financial institution having a rating of not less than A or its equivalent by
Standard & Poor's Corporation. Upon the acceptance of any appointment as
Administrative Agent or Documentation Agent hereunder by a successor
Administrative Agent or Documentation Agent, such successor Administrative Agent
or Documentation Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges, and duties of the retiring Administrative Agent or
Documentation Agent, and the retiring Administrative Agent or Documentation
Agent shall be discharged from its duties and obligations hereunder. After any
retiring Administrative Agent's or Documentation Agent's resignation, the
provisions of this Agreement and the other Loan Documents shall continue in
effect for its benefit in respect of any actions taken or omitted to be taken by
it while it was acting as Administrative Agent or Documentation Agent.

     12.10 Notification of Defaults and Events of Default.  Upon learning of the
           ----------------------------------------------                   
existence of a Default or an Event of Default, a Bank shall promptly notify the
Administrative Agent thereof. Upon receipt of any notice under this Section
12.10, the Administrative Agent shall promptly notify the other Banks of the
existence of such Default or Event of Default.

     12.11 Duties in the Case of Enforcement.  In case one of more Events of
           ---------------------------------                                
Default shall have occurred, and whether or not acceleration of the Obligations
shall have occurred, the Administrative Agent shall, if (a) so requested by the
Majority Banks and (b) the Banks have provided to the Administrative Agent such
additional indemnities and assurances against expenses and liabilities as the
Administrative Agent may reasonably request, proceed to enforce the provisions
of the Loan Documents and exercise all or any such other legal, equitable, and
other rights or remedies as it may have under the Loan Documents.  The Majority
Banks may direct the Administrative Agent in writing as to the method and the
extent of any such action, the Banks hereby agreeing to indemnify and hold the
Administrative Agent harmless from all liabilities incurred in respect of all
actions taken or omitted in accordance with such directions, provided that the
Administrative Agent need not comply with any such direction to the extent that
the Administrative Agent reasonably believes the Administrative Agent's
compliance with such direction to be unlawful or commercially unreasonable in
any applicable jurisdiction.

13.  EXPENSES.
     -------- 

     The Borrower shall upon demand either, as the Banks or the Administrative

2.    THE CREDIT FACILITIES.
      --------------------- 

      2.1   The Loans.
            --------- 

            (a) Subject to the terms and conditions set forth in Section 9
hereof, the Banks agree, severally in accordance with their respective
Commitment Percentages relating to the Commitment and not jointly, upon the
terms and subject to the conditions of this Agreement, to lend and re-lend to
the Borrower, from time to time on or after the Closing Date and up to but
excluding the Maturity Date, such sums as are requested by the Borrower up to a
maximum aggregate principal amount outstanding (after giving effect to all
amounts requested) at any one time equal to such Bank's Commitment, provided
                                                                    --------
that the (i) sum of the outstanding amount of the Loans (after giving effect to
all amounts requested) shall not at any time exceed the Commitment, and (ii) at
the time such Loan is requested, the aggregate amount of all Loans (as defined
in the Long-Term Credit Agreement) outstanding under the Long-Term Credit
Agreement shall not be less than the Total Commitment (as defined in the Long-
Term Credit Agreement). The Loans shall be made pro rata in accordance with each
                                                --------
Bank's Commitment Percentage; provided that the failure of any Bank to lend in
                              --------
accordance with this Agreement shall not release any other Bank or the
Administrative Agent from their obligations hereunder, nor shall any Bank have
any responsibility or liability in respect of a failure of any other Bank to
lend in accordance with this Agreement. Each request for a Loan and each
borrowing hereunder shall constitute a representation and warranty by the
Borrower that the conditions set forth in Section 9 have been satisfied on the
date of such request.

            (b) In the event that, at any time when the conditions precedent for
any Loan have been satisfied, a Bank fails or refuses to fund its portion of
such Loan, then, until such time as such Bank has funded its portion of such
Loan, (i) such non-funding Bank shall not have the right to vote regarding any
issue on which voting is required or advisable under this Agreement or any other
Loan Document, and the amount of such Bank's Commitment shall not be counted for
purposes of determining "Majority Banks" hereunder or for purposes of
determining Commitments representing one hundred percent (100%) of the Total
Commitment pursuant to Section 23 hereof, and (ii) any payments made by the
Borrower shall be applied to repay the interest on, and principal of, the Loans
held by the funding Banks until either (A) any Loan funded by the Administrative
Agent on behalf of a non-funding Bank has been repaid in full or (B) the
aggregate outstanding Loans, together with any accrued and unpaid interest
thereof, shall be held by the Banks pro rata in accordance with their respective
Commitment Percentages.

agreed upon and as are described in the Fee Letters.

Banks shall be reduced pro rata in accordance with their respective Commitment

Percentages of the amount specified in such notice or, as the case may be,

Commitments may be reinstated.

or at the time of receipt of any payment of principal on such Bank's Revolving
Note, as the case may be, an appropriate notation on such Bank's Record

payment. The outstanding amount of the Loans set forth on such Bank's Record
shall be prima facie evidence of the principal amount thereof owing and unpaid

to such Bank, but the failure to record, or any error in so recording, any such
amount on such Bank's Record shall not limit or otherwise affect the obligations
of the Borrower hereunder or under any Revolving Note to make payments of

     2.7  Conversion Options.
          ------------------ 

          (a) Conversion to Eurodollar Rate Loan. The Borrower may elect from
              ----------------------------------
time to time, subject to Section 2.9, to convert any outstanding Alternative
Base Rate Loan to a Eurodollar Rate Loan, provided that (i) the Borrower shall
                                          --------
give the Administrative Agent at least three (3) Eurodollar Business Days' prior
written notice of such election; and (ii) no Alternative Base Rate Loan may be
converted into a Eurodollar Rate Loan when any Default has occurred and is
continuing. The Administrative Agent shall notify the Banks promptly of any such
notice. On the date on which such conversion is being made, each Bank shall take
such action as is necessary to transfer its Commitment Percentage of such Loans
to its Eurodollar Lending Office. All or any part of outstanding Alternative
Base Rate Loans may be converted into a Eurodollar Rate Loan as provided herein,
provided that any partial conversion shall be in an aggregate principal amount
of $1,000,000 or an integral multiple of $1,000,000 in excess thereof.

       (b)  Continuation of Type of Loan.
            ---------------------------- 

            (i)   All Alternative Base Rate Loans shall continue as Alternative
Base Rate Loans until converted into Eurodollar Rate Loans as provided in

            (ii)  Any Eurodollar Rate Loan may, subject to Section 2.9, be
continued, in whole or in part, as a Eurodollar Rate Loan upon the expiration of
the Interest Period with respect thereto, provided that (A) the Borrower shall
give the Administrative Agent at least three (3) Eurodollar Business Days' prior
written notice of such election; (B) no Eurodollar Rate Loan may be continued as
such when any Default has occurred and is continuing, but shall be automatically
converted to an Alternative Base Rate Loan on the last day of the first Interest
Period relating thereto ending during the continuance of any Default; and (iii)
any partial continuation of a Eurodollar Rate Loan shall be in an aggregate
principal amount of $1,000,000 or an integral multiple of $1,000,000 in excess
thereof.

            (iii) If the Borrower shall fail to give any notice of continuation
of a Eurodollar Rate Loan as provided under this Section 2.7(b), the Borrower
shall be deemed to have requested a conversion of the affected Eurodollar Rate
Loan to an Alternative Base Rate Loan on the last day of the then current
Interest Period with respect thereto.

            (iv)  The Administrative Agent shall notify the Banks promptly when
any such continuation or conversion contemplated by this Section 2.7(b) is
scheduled to occur. On the date on which any such continuation or conversion is
to occur, each Bank shall take such action as is necessary to transfer its
Commitment Percentage of such Loans to its Domestic Lending Office or its
Eurodollar Lending Office as appropriate.

       (c) Conversion Requests.  All notices of the conversion or continuation
           -------------------                                                
of a Loan provided for in this Section 2.7 shall be in writing in the form of
Exhibit D hereto (or shall be given by telephone and confirmed by a writing in
- ---------                                                          
the form of Exhibit E hereto).  Each such notice shall specify (i) the principal
            ---------                                 
amount and Type of the Loan subject thereto, (ii) the date on which the current
Interest Period of such Loan ends if such Loan is a Eurodollar Rate Loan, and
(iii) the new Interest Period for such Loan if such Loan is a Eurodollar Rate
Loan. Promptly upon receipt of any such notice, the Administrative Agent shall
notify each of the Banks thereof. Each such notice shall be irrevocable and
binding on the Borrower.

     2.8  Funds for Loans.
          --------------- 

          (a) Funding Procedures.  Not later than 2:00 p.m. (Dallas time) on the
              ------------------                                                
proposed Drawdown Date of any Loans, each of the Banks will make available to
the Administrative Agent, at its Head Office, in immediately available funds,
the amount of such Bank's Commitment Percentage of the amount of the requested
Loans.  Upon receipt from each Bank of such amount, and upon receipt of the
documents required by Section 9 and the satisfaction of the other conditions set
forth therein, to the extent applicable, the Administrative Agent will make
available to the Borrower the aggregate amount of such Loans made available to
the Administrative Agent by the Banks.  The failure or refusal of any Bank to
make available to the Administrative Agent at the aforesaid time and place on
any Drawdown Date the amount of its Commitment Percentage of the requested Loans
shall not relieve any other Bank from its several obligation hereunder to make
available to the Administrative Agent the amount of such other Bank's Commitment
Percentage of any requested Loans, but no other Bank shall be liable in respect
of the failure of such Bank to make available such amount.

       (b) Advances by Administrative Agent.  The Administrative Agent may,
           --------------------------------                                
unless notified to the contrary by any Bank prior to a Drawdown Date, assume
that such Bank has made available to the Administrative Agent on such Drawdown
Date the amount of such Bank's Commitment Percentage of the Loans to be made on
such Drawdown Date, and the Administrative Agent may (but it shall not be
required to), in reliance upon such assumption, make available to the Borrower a
corresponding amount.  If any Bank makes available to the Administrative Agent
such amount on a date after such Drawdown Date, such Bank shall pay to the
Administrative Agent on demand an amount equal to the weighted average interest
rate paid by the Administrative Agent for federal funds acquired by the
Administrative Agent during each day included in such period, times the amount
of such Bank's Commitment Percentage of such Loans calculated on the basis of a
360-day year for the actual number of days elapsed.  A statement of the
Administrative Agent submitted to such Bank with respect to any amounts owing
under this paragraph shall be prima facie evidence of the amount due and owing
to the Administrative Agent by such Bank.  If the amount of such Bank's
Commitment Percentage of such Loans is not made available to the Administrative
Agent by such Bank within three (3) Business Days following such Drawdown Date,
the Administrative Agent shall be entitled to recover such amount from the
Borrower within one (1) Business Day after demand 

                                     -102-
<PAGE>
 
therefor, with interest thereon at the rate per annum applicable to the Loans
made on such Drawdown Date.

     2.9   Limit on Number of Eurodollar Rate Loans.  At no time shall there be
           ----------------------------------------                            
outstanding Eurodollar Rate Loans having more than five (5) different Interest
Periods.


3.   REPAYMENT OF THE LOANS.
     ---------------------- 

     3.1   Maturity.  The Borrower shall pay on the Maturity Date, and there
           --------                                                         
shall become absolutely due and payable on the Maturity Date, all of the Loans
outstanding on such date, together with any and all accrued and unpaid interest
thereon.  The Commitments shall terminate on the Maturity Date.

     3.2   Mandatory Repayments of Loans.  If at any time the sum of the
           -----------------------------                                
outstanding amount of the Loans exceeds the Commitment, then the Borrower shall
immediately pay the amount of such excess to the Administrative Agent for
application to the Loans.

     3.3   Optional Repayments of Loans.  The Borrower shall have the right, at
           ----------------------------                                        
its election, to repay the outstanding amount of the Loans, as a whole or in
part, at any time without penalty or premium, provided that any full or partial
repayment of the outstanding amount of any Eurodollar Rate Loans pursuant to
this Section 3.3 made on a date other than the last day of the Interest Period
relating thereto shall be subject to customary breakage charges as provided in
Section 4.9.  The Borrower shall give the Administrative Agent, no later than
10:00 a.m. (Dallas time) at least one (1) Business Day's prior written notice,
of any proposed repayment pursuant to this Section 3.3 of Alternative Base Rate
Loans, and three (3) Eurodollar Business Days' notice of any proposed repayment
pursuant to this Section 3.3 of Eurodollar Rate Loans, in each case, specifying
the proposed date of payment of Loans and the principal amount to be paid.  Each
such partial repayment of the Loans shall be in an amount of $10,000,000 or an
integral multiple of $1,000,000 in excess thereof, shall be accompanied by the
payment of accrued interest on the principal repaid to the date of payment, and
shall be applied, in the absence of instruction by the Borrower, first to the
principal of Alternative Base Rate Loans and then to the principal of Eurodollar
Rate Loans (in inverse order of the last days of their respective Interest
Periods).  Each partial repayment shall be allocated among the Banks, in
proportion, as nearly as practicable, to the respective unpaid principal amount
of each Bank's Loans, with adjustments to the extent practicable to equalize any
prior repayments not exactly in proportion.  Any amounts repaid under this
Section 3.3 may be reborrowed prior to the Maturity Date as provided in Section
2.6, subject to the conditions of Section 9.

4.   CERTAIN GENERAL PROVISIONS.
     -------------------------- 

     4.1   Application of Payments.
           ----------------------- 

           (a) Except as otherwise provided in this Agreement, all payments in
respect of any Loan shall be applied first to accrued and unpaid interest on
such Loan and second to the outstanding principal of such Loan.

                                     -103-
<PAGE>
 
           (b) If, at any time that a Default or Event of Default exists, the
Administrative Agent receives from the Borrower (or obtains funds for the
account of the Borrower, whether in connection with the enforcement of rights
under the Loan Documents or otherwise) less than the aggregate outstanding
amount of all Obligations hereunder, the Administrative Agent shall apply such
amounts in the following order of priority:

           First, to the payment of, or (as the case may be) the reimbursement
           -----
of the Administrative Agent for or in respect of all costs, expenses,
disbursements, and losses that shall have been incurred or sustained by the
Administrative Agent in connection with the collection of such monies by the
Administrative Agent, for the exercise, protection, or enforcement by the
Administrative Agent of all or any of the rights, remedies, powers, and
privileges of the Administrative Agent under this Agreement or any of the other
Loan Documents, or in support of any provision of adequate indemnity to the
Administrative Agent against any taxes or Liens that by Government Mandate shall
have, or may have, priority over the rights of the Administrative Agent to such
monies;

           Second, to the satisfaction of any costs or expenses or other amounts
           ------                                                               
required to be paid by the Borrower under this Agreement not otherwise specified
in this Section 4.1(b);

           Third, to the satisfaction of any accrued and unpaid fees hereunder;
           -----                                                               

           Fourth, to the satisfaction of any accrued and unpaid interest on any
           ------                                                               
Loans;

           Fifth, to the satisfaction of any outstanding principal amount of any
           -----                                                                
Loans; and

           Sixth, the excess, if any, shall be returned to the Borrower or to
           -----
such other Persons as are entitled thereto.

     4.2   Funds for Payments.
           ------------------ 

           (a) Payments to Administrative Agent.  All payments of principal,
               --------------------------------                             
interest, facility fees and any other amounts due hereunder or under any of the
other Loan Documents shall be made to the Administrative Agent, for the
respective accounts of the Banks and the Administrative Agent, at the
Administrative Agent's Head Office or at such other location that the
Administrative Agent may from time to time designate, in each case in
immediately available funds.

           (b) No Offset.  All payments by the Borrower hereunder and under any
               ---------
of the other Loan Documents shall be made without setoff or counterclaim and
free and clear of and without deduction for any taxes, levies, imposts, duties,
charges, fees, deductions, withholdings, compulsory loans, restrictions, or
conditions of any nature now or hereafter imposed or levied by any Government
Authority unless the Borrower is compelled by Government Mandate to make such
deduction or withholding. If any such obligation is imposed upon the Borrower
with respect to any amount payable by it hereunder or under any of the other
Loan Documents (other than with respect to taxes on the income or profits of any
Bank or the Administrative Agent), the Borrower will pay to the Administrative
Agent, for the account of the Banks or (as the case may be) the Administrative
Agent, on the date on which such amount is due and payable hereunder or under
such other Loan Document, such additional amount in Dollars as shall be
necessary to enable the Banks or the Administrative 

                                     -104-
<PAGE>
 
Agent to receive the same net amount which the Banks or the Administrative Agent
would have received on such due date had no such obligation been imposed upon
the Borrower. The Borrower will deliver promptly to the Administrative Agent
certificates or other valid vouchers for all taxes or other charges deducted
from or paid with respect to payments made by the Borrower hereunder or under
such other Loan Document. If a refund is received (either in cash or by means of
a credit against future tax obligations) by the Administrative Agent or any Bank
in respect of an amount previously paid by the Borrower pursuant to the
immediately preceding sentence as determined solely by the Administrative Agent
or such Bank, such refund shall be promptly paid over to the Borrower; provided,
                                                                       --------
however, in no event shall the Borrower have any right to receive or review tax
- ------- 
returns of any Bank or the Administrative Agent. Any Bank that is not a United
States person (as such term is defined in Section 7701(a)(30) of the Code) for
U.S. Federal income tax purposes agrees to provide to the Borrower on or prior
to the Closing Date two original signed copies of Internal Revenue Service Form
4224 or Form 1001 certifying to such Bank's entitlement to an exemption from
United States withholding tax with respect to payments to be made under this
Agreement and under any Revolving Note and from time to time upon the reasonable
written request of the Borrower after the Closing Date, such Bank will provide
to the Borrower two original signed copies of Internal Revenue Service Form 4224
or Form 1001 (or any successor forms) certifying to such Bank's entitlement to
an exemption from, or reduction in, United States withholding tax with respect
to payments to be made under this Agreement and under any Revolving Note.

      4.3   Computations.  All computations of interest with respect to
            ------------                                               
Alternative Base Rate Loans shall be based on a year of 365 days and paid for
the actual number of days elapsed.  All computations of interest with respect to
Eurodollar Rate Loans shall be based on a year of 360 days and paid for the
actual number of days elapsed.  Except as otherwise provided in the definition
of the term "Interest Period" with respect to Eurodollar Rate Loans, whenever a
payment hereunder or under any of the other Loan Documents becomes due on a day
that is not a Business Day, the due date for such payment shall be extended to
the next succeeding Business Day, and interest shall accrue during such
extension.

      4.4   Inability to Determine Eurodollar Rate.  In the event, prior to the
            --------------------------------------                             
commencement of any Interest Period relating to any Eurodollar Rate Loan, the
Administrative Agent shall determine that adequate and reasonable methods do not
exist for ascertaining the Eurodollar Rate that would otherwise determine the
rate of interest to be applicable to any Eurodollar Rate Loan during any
Interest Period, the Administrative Agent shall forthwith give notice of such
determination (which shall be conclusive and binding on the Borrower and the
Banks) to the Borrower and the Banks.  In such event (a) any Loan Request or
Conversion Request with respect to Eurodollar Rate Loans shall be automatically
withdrawn and shall be deemed a request for Alternative Base Rate Loans, (b)
each Eurodollar Rate Loan will automatically, on the last day of the then
current Interest Period relating thereto, become an Alternative Base Rate Loan,
and (c) the obligations of the Banks to make Eurodollar Rate Loans shall be
suspended until the Administrative Agent determines that the circumstances
giving rise to such suspension no longer exist, whereupon the Administrative
Agent shall so notify the Borrower and the Banks.

      4.5   Illegality.  Notwithstanding any other provisions herein, if any
            ----------                                                      
present or future Government Mandate shall make it unlawful for any Bank to make
or maintain Eurodollar Rate Loans, such Bank shall forthwith give notice of such
circumstances to the Borrower and the other Banks and thereupon (a) the
commitment of such Bank to make Eurodollar Rate Loans or convert 

                                     -105-
<PAGE>
 
Alternative Base Rate Loans to Eurodollar Rate Loans shall forthwith be
suspended, and (b) such Bank's Loans then outstanding as Eurodollar Rate Loans,
if any, shall be converted automatically to Alternative Base Rate Loans on the
last day of each then existing Interest Period applicable to such Eurodollar
Rate Loans or within such earlier period after the occurrence of such
circumstances as may be required by Government Mandate. The Borrower shall
promptly pay the Administrative Agent for the account of such Bank, upon demand
by such Bank, any additional amounts necessary to compensate such Bank for any
costs incurred by such Bank in making any conversion in accordance with this
Section 4.5 other than on the last day of an Interest Period, including any
interest or fees payable by such Bank to lenders of funds obtained by it in
order to make or maintain its Eurodollar Rate Loans hereunder.

      4.6   Additional Costs.  If any present or future applicable Government
            ----------------                                                 
Mandate (whether or not having the force of law), shall:

            (a) subject any Bank or the Administrative Agent to any tax, levy,
      impost, duty, charge, fee, deduction, or withholding of any nature with
      respect to this Agreement, the other Loan Documents, such Bank's
      Commitment, or the Loans (other than taxes based upon or measured by the
      income or profits of such Bank or the Administrative Agent), or

            (b) materially change the basis of taxation (except for changes in
      taxes on income or profits) of payments to any Bank of the principal of or
      the interest on any Loans or any other amounts payable to any Bank or the
      Administrative Agent under this Agreement or the other Loan Documents, or

            (c) impose, increase, or render applicable (other than to the extent
      specifically provided for elsewhere in this Agreement) any special
      deposit, reserve, assessment, liquidity, capital adequacy, or other
      similar requirements (whether or not having the force of law) against
      assets held by, or deposits in or for the account of, or loans by, or
      commitments of an office of any Bank, or

            (d) impose on any Bank or the Administrative Agent any other
      conditions or requirements with respect to this Agreement, the other Loan
      Documents, the Loans, such Bank's Commitment, or any class of loans or
      commitments of which any of the Loans or such Bank's Commitment forms a
      part, and the result of any of the foregoing is:

                (i)   to increase by an amount deemed by such Bank to be
            material to the cost to any Bank of making, funding, issuing,
            renewing, extending, or maintaining any of the Loans or such Bank's
            Commitment, or

                (ii)  to reduce, by an amount deemed by such Bank or the
            Administrative Agent, as the case may be, to be material, the amount
            of principal, interest, or other amount payable to such Bank or the
            Administrative Agent hereunder on account of such Bank's Commitment
            or any of the Loans, or

                (iii) to require such Bank or the Administrative Agent to make
            any payment that, but for such conditions or requirements described
            in clauses (a) 

                                     -106-
<PAGE>
 
            through (d), would not be payable hereunder, or forego any interest
            or other sum that, but for such conditions or requirements described
            in clauses (a) through (d), would be payable to such Bank or the
            Administrative Agent hereunder, in any case the amount of which
            payment or foregone interest or other sum is deemed by such Bank or
            the Administrative Agent, as the case may be, to be material and is
            calculated by reference to the gross amount of any sum receivable or
            deemed received by such Bank or the Administrative Agent from the
            Borrower hereunder, 

then, and in each such case, (x) the Borrower will, upon demand made by such
Bank or (as the case may be) the Administrative Agent at any time and from time
to time (such demand to be made in any case not later than the first to occur of
(A) the date one hundred and eighty (180) days after such event described in
clause (i), (ii), or (iii) giving rise to such demand, and (B) the date ninety
(90) days after both the payment in full of all outstanding Loans and
termination of the Commitments) and as often as the occasion therefor may arise,
pay to such Bank or the Administrative Agent such additional amounts as will be
sufficient to compensate such Bank or the Administrative Agent for such
additional cost, reduction, payment, foregone interest, or other sum, (y) the
Borrower shall be entitled, upon notice to the Administrative Agent and each
Bank given within ninety (90) days of any demand by a Bank under clause (x), to
repay in cash in full all, but not less than all, of the Loans of such Bank,
together with all accrued and unpaid interest on such Loans and any other
amounts owing to such Bank under the Loan Documents and terminate (in full and
not in part) such Bank's Commitment, and, (z) in the event the Borrower elects
to repay the Loans of any Bank under clause (y), each other Bank shall be
entitled, by notice to the Administrative Agent and the Borrower given within
forty-five (45) days after receipt of the notice referred to in clause (y), to
require the Borrower to repay in cash in full, within forty-five (45) days of
such notice under this clause (z), all, but not less than all, of the Loans of
such other Bank, together with all accrued and unpaid interest on such Loans and
any other amounts owing to such other Bank under the Loan Documents. Subject to
the terms specified above in this Section 4.6, the obligations of the Borrower
under this Section 4.6 shall survive repayment of the Loans and termination of
the Commitments.

      4.7   Capital Adequacy.  If after the date hereof any Bank or the
            ----------------                                           
Administrative Agent determines that (a) the adoption of or change in any
Government Mandate (whether or not having the force of law) regarding capital
requirements for banks or bank holding companies or any change in the
interpretation or application thereof by any applicable Government Authority
with appropriate jurisdiction, or (b) compliance by such Bank or the
Administrative Agent, or any corporation controlling such Bank or the
Administrative Agent, with any Government Mandate (whether or not having the
force of law) has the effect of reducing the return on such Bank's or the
Administrative Agent's commitment with respect to any Loans to a level below
that which such Bank or the Administrative Agent could have achieved but for
such adoption, change, or compliance (taking into consideration such Bank's or
the Administrative Agent's then existing policies with respect to capital
adequacy and assuming full utilization of such Entity's capital) by any amount
reasonably deemed by such Bank or (as the case may be) the Administrative Agent
to be material, then such Bank or the Administrative Agent may notify the
Borrower of such fact.  To the extent that the amount of such reduction in the
return on capital is not reflected in the Alternative Base Rate, (x) the
Borrower shall pay such Bank or (as the case may be) the Administrative Agent
for the amount of such reduction in the return on capital as and when such
reduction is determined upon presentation by such Bank or (as the case may be)
the Administrative Agent of a certificate in accordance with Section 4.8 hereof
(but in any case not later than the first to occur of (I) the date one hundred
and eighty (180) days after such 

                                     -107-
<PAGE>
 
adoption, change, or compliance causing such reduction, and (II) as to adoptions
of or changes in Government Mandates occurring prior to the repayment of the
Loans and the termination of the Commitment the date ninety (90) days after both
the payment in full of all outstanding Loans and termination of the
Commitments), (y) the Borrower shall be entitled, upon notice to the
Administrative Agent and each Bank given within ninety (90) days of any notice
by such Bank under the next preceding sentence, to repay in cash in full all,
but not less than all, of the Loans of such Bank, together with all accrued and
unpaid interest on such Loans and any other amounts owing to such Bank under the
Loan Documents and terminate (in full and not in part) such Bank's Commitment,
and, (z) in the event the Borrower elects to repay the Loans of any Bank under
clause (y), each other Bank shall be entitled, by notice to the Administrative
Agent and the Borrower given within forty-five (45) days after receipt of the
notice referred to in clause (y), to require the Borrower to repay in cash in
full, within forty-five (45) days of the notice under this clause (z), all, but
not less than all, of the Loans of such other Bank, together with all accrued
and unpaid interest on such Loans and any other amounts owing to such other Bank
under the Loan Documents. Each Bank shall allocate such cost increases among its
customers in good faith and on an equitable basis. Each Bank will use reasonable
efforts (subject to overall policy considerations of such Bank) to avoid or
mitigate any increased cost or obligation to prepay arising under this Section
to the greatest extent practicable (including transferring its Loans to another
lending office or affiliate of the Bank) unless, in the opinion of the Bank,
such efforts would be likely to result in the Bank (or its lending office or
affiliate) suffering a material economic, legal or regulatory disadvantage, and
provided, further, that nothing in this sentence shall affect or postpone the
Borrower's obligations hereunder, or any of the Bank's rights hereunder. Subject
to the terms specified above in this Section 4.7, the obligations of the
Borrower under this Section 4.7 shall survive repayment of the Loans and
termination of the Commitments.

      4.8   Certificate.  A certificate setting forth any additional amounts
            -----------                                                     
payable pursuant to Section 4.6 or Section 4.7 and a brief explanation of such
amounts which are due and in reasonable detail the basis of the calculation and
allocation thereof, submitted by any Bank or the Administrative Agent to the
Borrower, shall be conclusive evidence, absent manifest error, that such amounts
are due and owing.

      4.9   Indemnity.  The Borrower shall indemnify and hold harmless each Bank
            ---------                                                           
from and against any loss, cost, or expense (excluding loss of anticipated
profits) that such Bank may sustain or incur as a consequence of (a) default by
the Borrower in payment of the principal amount of or any interest on any
Eurodollar Rate Loans as and when due and payable, including any such loss or
expense arising from interest or fees payable by such Bank to lenders of funds
obtained by it in order to maintain its Eurodollar Rate Loans, (b) default by
the Borrower in making a borrowing or conversion after the Borrower has given
(or is deemed to have given) a Loan Request or a Conversion Request; or (c)
except as otherwise expressly provided in Section 3.3, the making of any payment
of a Eurodollar Rate Loan or the making of any conversion of any such Loan to an
Alternative Base Rate Loan on a day that is not the last day of the applicable

or 4.7, if the Borrower is obligated to pay to the Administrative Agent or any

repay the outstanding Loans in favor of such Bank, which repayment shall be
allocated solely to Loans in favor of such Bank, and in the event of such
repayment, such Bank shall cease to be a Bank under this Agreement and the Total
Commitment hereunder shall be reduced by the amount of the Commitment of such
Bank (and the Commitment Percentages of the remaining Banks shall be
recalculated accordingly), or (y)  replace such Bank with a new Bank reasonably
acceptable to the Administrative Agent, and such Bank hereby agrees to be so
replaced subject to the following:

            (a) The obligations of the Borrower hereunder to the Bank to be
replaced (including such increased or additional costs incurred from the date of

such Bank is replaced hereunder) shall be paid in full to such Bank concurrently
with such replacement;

            (b) The replacement Bank shall be a Bank that is not subject to the
increased costs arising under such Sections which may have effectuated the

               --------------
the other Loan Documents to which the Borrower, any of its Subsidiaries, or PGP

except as set forth on Schedule 5.1(d), neither the Borrower nor PGP nor
                       ---------------
Holdings has agreed, committed, or otherwise obligated itself to authorize or
issue any Equity Securities. All of the outstanding Equity Securities of the
Borrower are validly issued, fully paid, and non-assessable.

      5.2   Governmental Approvals.  The execution, delivery, and performance by
            ----------------------                                              
the Borrower, its Subsidiaries, and PGP of this Agreement and the other Loan
Documents to which the Borrower, any of its Subsidiaries, or PGP is or is to
become a party and the transactions contemplated hereby and thereby do not
require the approval or consent of, or filing with, any Government Authority

except Permitted Liens.  Each of the Borrower and its Subsidiaries enjoys quiet
possession under all leases relating to Real Estate or personal property to
which it is party as a lessee, except where such failure to have quiet
possession or be Fully Effective would not have a Material Effect.

      5.4   Financial Statements.  There has been furnished to the
            --------------------                                  
Administrative Agent and each of the Banks (a) a consolidated balance sheet of
the Borrower as at December 31, 1997, December 31, 1996 and December 31, 1995,
and a consolidated statement of income and cash flow of the Borrower for the
fiscal year then ended, certified by the Borrower's independent certified public
accountants, and (b) unaudited consolidated balance sheets of the Borrower as at
March 31, 1997, June 30, 1997, and September 30, 1997 and consolidated
statements of income and of cash flow of the Borrower for the respective fiscal
periods then ended and as set forth in the Borrower's Quarterly Reports on Form
10-Q for such fiscal quarters.  With respect to the financial statements
prepared in accordance with clause (a) above, such balance sheet and statement
of income have been prepared in accordance with GAAP, and present fairly in all
material respects the financial position of the Borrower and its Subsidiaries as
at the close of business on the respective dates thereof and the results of
operations of the Borrower and its Subsidiaries for the fiscal periods then
ended; or, in the case of the financial statements referred to in clause (b),
have been prepared in accordance with Rule 10-01 of Regulation S-X of the
Securities and Exchange Commission, and contain all adjustments necessary for a
fair presentation of (i) the results of operations of the Borrower for the
periods covered thereby, (ii) the financial position of the Borrower at the date
thereof, and (iii) the cash flows of the Borrower for periods covered thereby
(subject to year-end adjustments).  There are no contingent liabilities of the
Borrower or its Subsidiaries as of such dates involving material amounts, known
to the executive management of the Borrower that (x) should have been disclosed
in said balance sheets or the related notes thereto in accordance with GAAP and
the rules and regulations of the Securities and Exchange Commission, and (y)
were not so disclosed.

      5.5   No Material Changes.  Except as set forth on Schedule 5.5, no change
            -------------------                          ------------           
in the Business of the Borrower and its Subsidiaries, taken as a whole, has
occurred since December 31, 1996 that has resulted in a Material Effect.

      5.6   Permits.  The Borrower and its Subsidiaries have all Permits
            -------                                                     
necessary or appropriate for them to conduct their Business, except where the
failure to have such Permits would 

                                     -111-
<PAGE>
 
not be likely to have a Material Effect. All of such Permits are in full force
and effect. Without limiting the foregoing, the Borrower is duly registered as
an "investment adviser" under the Investment Advisers Act of 1940 and under the
applicable laws of each state in which such registration is required in
connection with the investment advisory business of the Borrower and in which
the failure to obtain such registration would be likely to have a Material
Effect; PIMCO Funds Distributors LLC is duly registered as a "broker/dealer"
under the Securities Exchange Act of 1934 and under the securities or blue sky
laws of each state in which such registration is required in connection with the
business conducted by PIMCO Funds Distributors LLC and where a failure to obtain
such registration would be likely to have a Material Effect, and is a member in
good standing of the National Association of Securities Dealers, Inc.; no
Proceeding is pending or threatened with respect to the suspension, revocation,
or termination of any such registration or membership, and the termination or
withdrawal of any such registration or membership is not contemplated by the
Borrower or PIMCO Funds Distributors LLC except, only with respect to
registrations by the Borrower and PIMCO Funds Distributors LLC required under
state law, as would not be likely to have a Material Effect.

      5.7   Litigation.  Except as disclosed on Schedule 5.7 hereto as of the
            ----------                          ------------          
Closing Date, or as disclosed to the Administrative Agent and the Banks in
writing with respect to any subsequent date, there is no Proceeding of any kind
pending against the Borrower, any of its Subsidiaries, or PGP with an amount in
controversy exceeding the Material Amount. None of such Proceedings (a) is
reasonably likely to, either in any case or in the aggregate, have a Material
Effect, or (b) questions the validity of this Agreement or any of the other Loan
Documents, or any action taken or to be taken pursuant hereto or thereto.

      5.8   Material Contracts.  Except as would not be likely to have a
            ------------------                                          
Material Effect, each Contract to which any of the Borrower and its Subsidiaries

(including investment advisory contracts and investment company distribution
plans) (a) is Fully Effective, (b) is not subject to any default or event of
default with respect to the Borrower, any of its Subsidiaries or, to the best
knowledge of the executive management of the Borrower, any other party, (c) is
not subject to any notice of termination given or received by the Borrower or
any of its Subsidiaries, and (d) is, to the best knowledge of the executive
management of the Borrower, the legal, valid, and binding obligation of each
party thereto other than the Borrower and its Subsidiaries enforceable against
such parties according to its terms.

      5.9   Compliance with Other Instruments, Laws.  None of the Borrower, its
            ---------------------------------------                            
Subsidiaries, or PGP is in violation of or default under (a) any provision of
its certificate of incorporation or by-laws, or its certificate of limited
partnership or agreement of limited or general partnership, as the case may be,
(b) except for the Note Agreement, any Contract to which it is or may be subject
or by which it or any of its properties are or may be bound, or (c) any
Government Mandate, including Government Mandates relating to occupational
safety and employment matters, except (with respect to subsections (b) and (c)),
in any case, where such violation or default would not be likely to have a
Material Effect.

      5.10  Tax Status.  The Borrower and its Subsidiaries (a) have made or
            ----------                                                     
filed all federal and state income and all other tax returns, reports, and
declarations required by any Government Authority to which any of them is
subject, except where the failure to make or file the same would not be likely
to have a Material Effect, (b) have paid all taxes and other governmental
assessments and 

                                     -112-
<PAGE>
 
charges due, except those being contested in good faith and by appropriate
Proceedings or those where a failure to pay is not reasonably likely to have a
Material Effect, and (c) have set aside on their books provisions reasonably
adequate for the payment of all taxes for periods subsequent to the periods to
which such returns, reports, or declarations apply. There are no unpaid taxes in
any material amount claimed to be due from the Borrower or any of its
Subsidiaries by any Government Authority, and the executive management of the
Borrower knows of no basis for any such claim.

      5.11    No Event of Default.  No Default has occurred and is continuing.
              -------------------                                             

      5.12    Holding Company and Investment Company Acts.  Neither the Borrower
              -------------------------------------------                       
nor any of its Subsidiaries is a "holding company", or a "subsidiary company" of
a "holding company", as such terms are defined in the Public Utility Holding
Company Act of 1935.  Neither the Borrower nor any of its Subsidiaries is an
"investment company", as such term is defined in the 1940 Act, required to be
registered in accordance with such Act.

      5.13    Insurance.  The Borrower and its Subsidiaries maintain insurance
              ---------                                                       
with financially sound and reputable insurers in such coverage amounts, against
such risks, with such deductibles and upon such other terms, or are self-insured
in respect of such risks (with appropriate reserves to the extent required by
GAAP), as is reasonable and customary for firms engaged in businesses similar to
those of the Borrower and its Subsidiaries.  All policies of insurance
maintained by the Borrower or its Subsidiaries are Fully Effective.  All
premiums due on such policies have been paid or accrued on the books of the
Borrower or its Subsidiaries, as appropriate.

      5.14    Certain Transactions.  Except in connection with (a) the PGP
              --------------------                                        
Refinancing, (b) transactions occurring in the ordinary course of business, (c)
transactions between the Borrower and Holdings authorized pursuant to the
Amended and Restated Operating Agreement dated as of January 1, 1998 by and
between Holdings and the Borrower, so long as PGP shall remain the sole general
partner of Holdings, (d) transactions with a Public General Partner that was
formerly a limited partner of the Borrower, and (e) transactions occurring on
fair and reasonable terms no less favorable to the Borrower and its Subsidiaries
taken as a whole than would be obtained in comparable arms' length transactions
with Persons that are not Affiliates of the Borrower or its Subsidiaries, none
of the officers, directors, partners, or employees of the Borrower or any of its
Subsidiaries, or, to the knowledge of the executive management of the Borrower,
any Entity (other than a Subsidiary) in which any such officer, director,
partner, or employee has a substantial interest or is an officer, director,
trustee, or partner, is at present a party to any transaction with the Borrower
or any of its Subsidiaries (other than for or in connection with services as
officers, directors, partners, or employees, as the case may be), including any
Contract providing for the furnishing of services to or by, providing for rental
of real or personal property to or from, or otherwise requiring payments to or
from any such officer, director, partner, employee, or Entity.

      5.15    Employee Benefit Plans.
              ---------------------- 

              (a) In General.  Set forth on Schedules Schedule 5.15 is a list of
                  ----------                -----------------------             
each Employee Benefit Plan and Multiemployer Plan of the Borrower and its
Subsidiaries as of the Closing Date.  After the Closing Date, any additional
Employee Benefit or Multiemployer Plan shall be disclosed to the Administrative
Agent in writing.  Each Employee Benefit Plan has been maintained and operated
in compliance in all material respects with the provisions of ERISA and, to the
extent applicable, the 

                                     -113-
<PAGE>
 
Code, including the provisions thereunder respecting prohibited transactions,
except where the failure to so comply would not be likely to have a Material
Effect.

          (b) Terminability of Welfare Plans.  Under each Employee Benefit Plan
              ------------------------------                                   
which is an employee welfare benefit plan within the meaning of (S)3(1) or
(S)3(2)(B) of ERISA, no benefits are due unless the event giving rise to the
benefit entitlement occurs prior to plan termination (except as required by
Title I, Part 6 of ERISA).  The Borrower or an ERISA Affiliate, as appropriate,
may terminate each such Plan at any time (or at any time subsequent to the
expiration of any applicable bargaining agreement) in the discretion of the
Borrower or such ERISA Affiliate without liability to any Person, except as
would not be likely to have a Material Effect.

          (c) Guaranteed Pension Plans.  Each contribution required to be made
              ------------------------                                        
to a Guaranteed Pension Plan, whether required to be made to avoid the
incurrence of an accumulated funding deficiency, the notice or lien provisions
of (S)302(f) of ERISA, or otherwise, has been timely made.  No waiver of an
accumulated funding deficiency or extension of amortization periods has been
received with respect to any Guaranteed Pension Plan.  No liability to the PBGC
(other than required insurance premiums, all of which have been paid) has been
incurred by the Borrower or any ERISA Affiliate with respect to any Guaranteed
Pension Plan and there has not been any ERISA Reportable Event, or any other
event or condition which presents a material risk of termination of any
Guaranteed Pension Plan by the PBGC.  Based on the latest valuation of each
Guaranteed Pension Plan (which in each case occurred within fifteen (15) months
of the date of this representation), and on the actuarial methods and
assumptions employed for that valuation, the aggregate benefit liabilities of
all such Guaranteed Pension Plans within the meaning of (S)4001 of ERISA did not
exceed the aggregate value of the assets of all such Guaranteed Pension Plans by
more than $10,000,000, disregarding for this purpose the benefit liabilities and
assets of any Guaranteed Pension Plan with assets in excess of benefit
liabilities.

          (d) Multiemployer Plans.  Neither the Borrower nor any ERISA Affiliate
              -------------------
has incurred any material liability (including secondary liability) to any
Multiemployer Plan as a result of a complete or partial withdrawal from such
Multiemployer Plan under (S)4201 of ERISA or as a result of a sale of assets
described in (S)4204 of ERISA.  Neither the Borrower nor any ERISA Affiliate has
been notified that any Multiemployer Plan is in reorganization or insolvent
under and within the meaning of (S)4241 or (S)4245 of ERISA or that any
Multiemployer Plan intends to terminate or has been terminated under (S) 4041A
of ERISA.

    5.16. Use of Proceeds; Regulations U and X.
          ------------------------------------ 

          (a) The proceeds of the Loans shall be used by the Borrower to
refinance certain Indebtedness, for working capital and for general corporate
purposes and may be used to repay the Private Placement Notes.

          (b) No portion of any Loan is to be used for the purpose of purchasing
or carrying any "margin security" or "margin stock" as such terms are used in
Regulations U and X of the Board of Governors of the Federal Reserve System, 12
C.F.R. Parts 221 and 224.

    5.17  Environmental Compliance.  To the best of the Borrower's knowledge:
          ------------------------                                           

                                     -114-
<PAGE>
 
          (a) none of the Borrower, its Subsidiaries, PGP, and any operator of
the Real Estate or any operations thereon is in violation, or alleged violation,
of any Government Mandate or Permit pertaining to environmental, safety, or
public health matters, including the Resource Conservation and Recovery Act
("RCRA"), the Comprehensive Environmental Response, Compensation and Liability
- ------                                                                        
Act of 1980 ("CERCLA"), the Superfund Amendments and Reauthorization Act of 1986
              ------                                                            
("SARA"), the Federal Clean Water Act, the Federal Clean Air Act, and the Toxic
  ----                                                                         
Substances Control Act (hereinafter "Environmental Laws"), which violation would
                                     ------------------                         
be likely to have a Material Effect;

          (b) neither the Borrower nor any of its Subsidiaries has received
notice from any third party, including any Government Authority, (i) that any
one of them has been identified by the United States Environmental Protection
Agency ("EPA") as a potentially responsible party under CERCLA with respect to a
         ---

hazardous substances as defined by 42 U.S.C. (S)9601(14), any pollutant or
contaminant as defined by 42 U.S.C. (S)9601(33) and any toxic substances, oil,
hazardous materials, or other chemicals or substances regulated by any
Environmental Laws ("Hazardous Substances") that any one of them has generated,
                     --------- ----------

accounting officer, and general counsel of the Borrower) becomes aware thereof

written report supplemental to any oral report is made) to any Government
Authority, and (ii) upon becoming aware thereof, of any Proceeding, including a

has the potential, in the Borrower's reasonable judgement, to have a Material
Effect.

any of its Subsidiaries is or becomes a party that could reasonably be expected
by the Borrower to have a Material Effect (or of any material change in any such
Proceedings of which the Borrower has previously given notice).  Any such notice
will state the nature and status of such Proceedings.  The Borrower will give
notice to the Administrative Agent and each of the Banks, in writing, in form

the Administrative Agent and the Banks at least forty (40) days prior to any
proposed Change of Control Date, (i) except to the extent the Borrower may be
prohibited by U.S. securities laws from giving such a notice, in which case the
Borrower shall do so as soon as may be legally permissible and (ii) except to
the extent the Borrower may be prohibited by a written confidentiality covenant,
in which case the Borrower shall do so as soon as it is contractually permitted
and in any event not later than forty-eight (48) hours prior to such Change of
Control.  Any Control Change Notice shall describe the principal facts and
circumstances of such Change of Control known to the Borrower in reasonable
detail (including the Change of Control Date or, if the Borrower does not have
knowledge of the Change of Control Date, the Borrower's best estimate of such
Change of Control Date).  In the event the Borrower shall not have designated
the Change of Control Date in its Control Change Notice, the Borrower shall keep
the Administrative Agent and the Banks informed as to any changes in the
estimated Change of Control Date and shall provide written notice to the
Administrative Agent and the Banks specifying the Change of Control Date
promptly upon obtaining knowledge thereof.

(including those of its suppliers and vendors) that is material to the
Borrower's or any of its Subsidiaries' business and operations will not be Year

otherwise, proceed to protect and enforce its rights by any appropriate
Proceeding, whether for the specific performance of any covenant or agreement
contained in this Agreement and the other Loan Documents or any instrument
pursuant to which the Obligations to such Bank are evidenced, including as
permitted by applicable Government Mandate the obtaining of the ex parte

each other Bank that (a) if an amount to be set off is to be applied to

and shall retain and apply to the payment of the Revolving Note or Revolving
Notes held by such Bank any amount in excess of its ratable portion of the
payments received by all of the Banks with respect to the Revolving Notes held
by all of the Banks (exclusive of payments to be made for the account of less
than all of the Banks as provided in Sections 4.6, 4.7, 4.8, and 4.9), such Bank
will make such disposition and arrangements with the other Banks with respect to
such excess, either by way of distribution, pro tanto assignment 
                                            ---------

respect of the Revolving Notes held by it its proportionate payment as
contemplated by this Agreement; provided that if all or any part of such excess
                                --------
payment is thereafter recovered from such Bank, such disposition and
arrangements shall be rescinded and the amount restored to the extent of such

assumed herein or therein shall be implied to have been assumed by the
Administrative Agent or the Documentation Agent.  The relationship between the
Administrative Agent and the Banks and between the Documentation Agent and the
Banks is and shall be that of agent and principal only, and nothing contained in
this Agreement or any of the other Loan Documents shall be construed to
constitute the Administrative Agent or the Documentation Agent as a trustee for
any Bank.

        12.2  Employees and Administrative Agents.  Each of the Administrative
              -----------------------------------                             
Agent and the Documentation Agent may exercise its powers and execute its duties
by or through employees or agents and shall be entitled to take, and to rely on,
advice of legal counsel concerning all matters pertaining to its rights and
duties under this Agreement and the other Loan Documents.  Each of the
Administrative Agent and the Documentation Agent may utilize the services of
such Persons as it in its sole discretion may reasonably determine.

nor any other Person assisting them in their duties nor any agent or employee
thereof, shall be liable for any waiver, consent or approval given or any action
taken, or omitted to be taken, in good faith by it or them hereunder or under
any of the other Loan Documents, or in connection herewith or therewith, or be
responsible for the consequences of any oversight or error of judgment
whatsoever, except that the Administrative Agent, the Documentation Agent or
such other Person, as the case may be, may be liable for losses due to its
willful misconduct or gross negligence.

        12.4  No Representations.  Neither the Administrative Agent nor the
              ------------------                                           
Documentation Agent shall be responsible for the execution (other than on its
own behalf) or validity or enforceability of this Agreement, the Revolving
Notes, any of the other Loan Documents or any instrument at any time
constituting, or intended to constitute, collateral security for the Revolving
Notes, or for the value of any such collateral security or for the validity,
enforceability, or collectability of any such amounts owing with respect to the
Revolving Notes, or for any recitals or statements, warranties, or
representations made herein or in any of the other Loan Documents or in any
certificate or instrument hereafter furnished to it by or on behalf of the
Borrower, or be bound to ascertain or inquire as to the performance or
observance of any of the terms, conditions, covenants, or agreements herein or
in any instrument at any time constituting, or intended to constitute,
collateral security for the Revolving Notes or to inspect any of the properties,
books, or records of the Borrower or any of its Subsidiaries.

Neither the Administrative Agent nor the Documentation Agent shall be bound to
ascertain whether any notice, consent, waiver, or request delivered to it by the
Borrower or any holder of any of the Revolving Notes shall have been duly
authorized or is true, accurate, and complete. Neither the Administrative Agent
nor the Documentation Agent has made nor does it now make any representations or
warranties, express or implied, nor does it assume any liability to the Banks,
with respect to the credit worthiness or financial conditions of the Borrower or
any of its Subsidiaries. Each Bank acknowledges that it has, independently and
without reliance upon the Administrative Agent, the Documentation Agent or any
other Bank, and based upon such information and documents as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement.

        12.5  Payments.
              -------- 

              (a)  Payments to Administrative Agent.  A payment by the Borrower
                   --------------------------------

for the account of any Bank shall constitute a payment to such Bank. The
Administrative Agent shall promptly distribute to each Bank such Bank's pro rata

                   ------------------------------------
opinion of the Administrative Agent the distribution of any amount received by
it in such capacity hereunder, under the Revolving Notes, or under any of the
other Loan Documents might involve it in liability, it may refrain from making
distribution until its right to make the same shall have been adjudicated by a
court of competent jurisdiction.  If any Government Authority shall adjudge that
any amount received and distributed by the Administrative Agent is to be repaid,
each Person to whom any such distribution shall have been made shall either
repay to the Administrative Agent its proportionate share of the amount so
adjudged to be repaid or shall pay over the same in such manner and to such
Persons as shall be determined by such Government Authority.

the Borrower.  If no successor Administrative Agent or Documentation Agent shall
have been so appointed by the Majority Banks and shall have accepted such
appointment within thirty (30) days after the retiring Administrative Agent's or

12.10, the Administrative Agent shall promptly notify the other Banks of the
existence of such Default or Event of Default.

        12.11  Duties in the Case of Enforcement.  In case one of more Events of
               ---------------------------------                                
Default shall have occurred, and whether or not acceleration of the Obligations
shall have occurred, the Administrative Agent shall, if (a) so requested by the
Majority Banks and (b) the Banks have provided to the Administrative Agent such
additional indemnities and assurances against expenses and liabilities as the
Administrative Agent may reasonably request, proceed to enforce the provisions
of the Loan Documents and exercise all or any such other legal, equitable, and
other rights or remedies as it may have under the Loan Documents.  The Majority
Banks may direct the Administrative Agent in writing as to the method and the
extent of any such action, the Banks hereby agreeing to indemnify and hold the
Administrative Agent harmless from all liabilities incurred in respect of all
actions taken or omitted in accordance with such directions, provided that the
Administrative Agent need not comply with any such direction to the extent that
the Administrative Agent reasonably believes the Administrative Agent's
compliance with such direction to be unlawful or commercially unreasonable in
any applicable jurisdiction.

BANK OR THE ADMINISTRATIVE AGENT WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVERS AND (B) ACKNOWLEDGES THAT EACH OF THE
ADMINISTRATIVE AGENT AND THE BANKS HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS TO WHICH IT IS A PARTY BY, AMONG OTHER THINGS, THE
WAIVERS AND CERTIFICATIONS CONTAINED HEREIN.


23.    CONSENTS, AMENDMENTS, WAIVERS.
       ----------------------------- 

       Except as otherwise expressly provided in this Agreement, any term of
this Agreement, the other Loan Documents, or any other instrument related hereto
or mentioned herein may be amended with, but only with, the written consent of
the Borrower and the Majority Banks.  Any consent or approval required or
permitted by this Agreement to be given by the Banks may be given, any
acceleration of Amounts owing under the Loan Documents may be rescinded, and the
performance or observance by the Borrower of any terms of this Agreement, the
other Loan Documents, or any other instrument related hereto or mentioned herein
or the continuance of any Default or Event of Default may be waived (either
generally or in a particular instance and either retroactively or prospectively)
with, but only with, the written consent of the Majority Banks. Notwithstanding
the foregoing, the rate of interest on the Revolving Notes (other than interest
accruing pursuant to Section 4.10 following the effective date of any waiver by
the Majority Banks of the Default or Event of Default relating thereto), the
term of the Revolving Notes, the amount of the Commitments of the Banks, the
timing of payments of principal, interest or fees due hereunder and the amount
of facility fees hereunder may not be changed without the written consent of the
Borrower and the written consent of Banks holding Commitments representing one
hundred percent (100%) of the Total Commitment; neither this Section 23 nor the
definition of Majority Banks may be amended without the written consent of all
of the Banks; and Section 12 may not be amended without the written consent of
the Administrative Agent.  No waiver shall extend to or affect any obligation
not expressly waived or impair any right consequent thereon.  No course of
dealing or delay or omission on the part of any Bank in exercising any right
shall operate as a waiver thereof or otherwise be prejudicial thereto.  No
notice to or demand upon the Borrower shall entitle the Borrower to other or
further notice or demand in similar or other circumstances.

24.    SEVERABILITY.
       ------------ 

       The provisions of this Agreement are severable and if any one clause or
provision hereof shall be held invalid or unenforceable in whole or in part in
any jurisdiction, then such invalidity or unenforceability shall affect only
such clause or provision, or part thereof, in such jurisdiction, and shall not
in any manner affect such clause or provision in any other jurisdiction, or any
other clause or provision of this Agreement in any jurisdiction.


25.    CONFIDENTIALITY.
       --------------- 

       Unless specifically authorized otherwise by the Borrower, the
Administrative Agent, the Documentation Agent and the Banks shall hold all non-
public information obtained pursuant to the requirements of this Agreement in
accordance with the Administrative Agent's, the Documentation Agent's or such
Banks' customary procedures for handling confidential information of this nature
and in accordance with safe and sound banking practices and shall use such non-
public information only for purposes of the transactions contemplated by this
Agreement. Any party hereto or any party that has agreed to be bound by the
terms of this Section 25 may make disclosure (a) to its Affiliates or (b)
reasonably required by a bona fide offeree, transferee or participant in
accordance with the contemplated transfer or participation or as required or
requested by any governmental authority or representative thereof or pursuant to
legal process; provided that such Affiliate, offeree, transferee or participant
shall have agreed in writing to be bound by the provisions of this Section 25.
In no event shall the Administrative Agent, the Documentation Agent or any Bank
be obligated to return any materials furnished to it by the Borrower in
connection with this Agreement.
