         2.1     Availability and Adjustments.

                 (a)      Agreement to Lend.  Subject to subparagraphs (1)
         through (4) below (the "Lending Sublimits"), each Lender severally
         agrees to make Loans to the Company and participate in purchases of
         Discount Advances (and, to the extent and not to exceed the amounts
         provided in the second Recital of this Agreement and in no event to

         Lender agrees to make Swingline Advances to the Borrowing

         from time to time through the Business Day immediately preceding the
         Termination Date, provided that, on any date, after giving effect to
         such Loans and all other Loans that the Company or any Borrowing

                                      -31-
<PAGE>   38

                          (1)  the aggregate principal balance then outstanding
                 under all Loans made by any Lender under this Agreement
                 (excluding the aggregate principal balance then outstanding of
                 any Bid Loans made by such Lender and any portion of Discount
                 Advances made by such Lender which have been sold or, will on
                 such date be simultaneously sold, to the other Lenders under
                 Section 2.4) shall not at any time exceed the sum of (i) such
                 Lender's then-current General Commitment, and (ii) such
                 Lender's then-current Swingline Commitment, if any;

                          (2)  the aggregate principal balance of all Loans
                 outstanding under this Agreement plus the aggregate face
                 amount of all Outstanding CPNs shall not at any time exceed
                 the then-current Aggregate Commitment;

                          (3)  the Credit Requirement shall not exceed the
                 Borrowing Base;

                          (4)  except as otherwise set forth in Section 2.5(c),
                 the aggregate principal balance of all Swingline Advances
                 outstanding under this Agreement at any time shall not exceed
                 the Swingline Commitment.

         Subject to the terms hereof, the Company and the Borrowing
         Subsidiaries may borrow, repay and reborrow amounts hereunder.

                 (b)      Optional Increases in Aggregate Commitments.  The
         Company shall have the right to increase the Aggregate Commitment, but
         not to an amount in excess of $750,000,000, by obtaining additional
         Commitments, either from one or more of the Lenders or another lending
         institution provided that (A) the Agent has approved the identity of
         any such new Lender, (B) any such new Lender assumes all of the rights
         and obligations of a "Lender" hereunder, and (C) the Agent has
         received a " New/Modified Commitment Supplement" in the form of
         Exhibit H attached hereto, which supplement shall be executed by the
         Company, each Borrowing Subsidiary, the Agent and any Lender modifying
         its Commitment thereby.  Each New/Modified Commitment Supplement shall
         be deemed to amend Exhibit C to the extent necessary to reflect any
         changes in the Commitments hereunder, and the Agent shall promptly





                                      -32-
<PAGE>   39

         deliver a copy of such supplement to each Lender whose Commitment
         Percentage is affected thereby.

                 (c)      Optional Reductions in Aggregate Commitments.  The
         Company shall have the right to reduce the Aggregate Commitment upon
         ten Business Days' prior written notice to the Agent, provided that
         such voluntary reductions shall be made only in multiples of
         $10,000,000.  Upon a reduction of the Aggregate Commitment pursuant to
         the preceding sentence, each Lender's General Commitment shall be
         decreased pro rata in accordance with such Lender's Adjusted
         Commitment Percentage.  On or before the effective date of any such
         reduction, the Company shall, if necessary, repay sufficient Loans to
         prevent the remaining outstanding Loans hereunder, after giving effect
         to such permanent reduction, from exceeding the Lending Sublimits.


         2.2     Fees.

                 The Company shall pay the following fees (the "Fees"):

                 (a)      Facility Fee.  A facility fee based on the Aggregate
         Commitment from time to time, calculated at the Facility Fee Rate,
         changing when and as such rate changes, expressed as a per diem rate
         on the actual Aggregate Commitment for each day during the preceding
         full or partial calendar quarter, payable in arrears, on or before the
         fifth Business Day of each calendar quarter and on the Termination
         Date.  This fee shall be allocated among the Lenders on a pro rata
         basis in accordance with their respective Commitments (including any
         Swingline Commitment) on each day during such quarter.

                 (b)      Amendment Fee.  An amendment fee of $1,000 to each
         Lender for each amendment to this Agreement requested solely by the
         Company during the remaining portion of calendar year 1997, and each
         amendment requested solely by the Company in excess of two (2)
         amendments during a subsequent calendar year.

                 (c)      Other Fees Payable to Agent.  Any fees payable to the
         Agent pursuant to any applicable letter agreements between the Agent
         and the Company.





                                      -33-
<PAGE>   40

                 (d)      Collateral Agent Fees.  Collateral Agent fees payable
         to Collateral Agent for its services rendered pursuant to the Security
         Agreement as agreed to by the Company and the Collateral Agent from
         time to time.

                 (e)      Fees Payable in Connection with Discount Loans or
         Swingline Buydown Advances.  Any deficiency fees owing to the Balance
         Banks or the Swingline Lender under the Balance Bank Agreements due to
         the Company's failure to maintain sufficient deposits with such
         Balance Banks or the Swingline Lender and any other fees owing under
         the Balance Bank Agreements.


         2.3     Advances.

                 (a)      Types of Advances.  Each Advance hereunder shall
consist of Loans made from one or more of the Lenders and requested by the
Company or a Borrowing Subsidiary in accordance with Section 2.9.  Subject to
the terms and conditions herein, Eurodollar Advances, Alternate Base Rate
Advances and Federal Funds Advances shall be generally available as permitted
by the Lending Sublimits.  Discount Advances shall be available only as
provided in Section 2.4.  Swingline Advances shall be available as provided in
Section 2.5.  Bid Loans shall be available as provided in Section 2.6.
Notwithstanding anything to the contrary contained in this Agreement, at any
time during the continuance of a Default the Agent may (and at the direction of
the Required Lenders shall) declare by notice to the Company that no Advance
may be made as, converted into or continued as a Eurodollar Advance or a
Discount Advance, and each such Advance shall automatically be converted into a
Federal Funds Advance at the expiration of the interest period applicable
thereto.

                 (b)      Rate Options.  Eurodollar Advances, Alternate Base
Rate Advances, Federal Funds Advances, Swingline Buydown Advances and Overnight
Transaction Advances shall accrue interest at the Eurodollar Rate, the
Alternate Base Rate, the Federal Funds Rate, the Swingline Buydown Rate and the

interest but shall be made on a discounted basis by one or more Balance Banks
and shall be sold to the other Lenders in accordance with Section 2.4.





                                      -34-
<PAGE>   41

                 (c)      Funding of Advances.  Discount Advances, Swingline
Advances and Bid Loans shall be funded by the Lenders as provided in Sections
2.4, 2.5 and 2.6, respectively.  All other Advances shall be funded on a pro
rata basis among all Lenders in accordance with each Lender's Adjusted
Commitment Percentage.

                 (d)      Reallocation of Swingline Advances.  Upon the
election of the Swingline Lender at any time, all outstanding Swingline
Advances (including Swingline Advances made pursuant to Section 2.5(c) below)
designated by the Swingline Lender shall be reallocated among all Lenders in
accordance with each Lender's Adjusted Commitment Percentage, and each such
Swingline Advance shall thereafter be deemed for all purposes a Federal Funds
Advance.  Notwithstanding the preceding sentence or any other provision of this
Agreement, no portion of any Swingline Advance shall be reallocated to any
Lender to the extent such reallocation would cause such Lender's share of the
aggregate unpaid principal amount of all Loans (other than Bid Loans) then
outstanding under this Agreement to exceed its General Commitment hereunder.

                 (e)      Reallocation Upon Default.  Automatically after the
occurrence of an Event of Default described in Section 10.1(k) and upon the
request of any Lender during the continuance of any other Event of Default, (i)
all Swingline Advances made in accordance with this Agreement, Federal Funds
Advances and Alternate Base Rate Advances (excluding Bid Loans) shall be
immediately reallocated among all Lenders in accordance with each Lender's
Commitment Percentage, and each Swingline Advance shall thereafter be deemed
for all purposes a Federal Funds Advance, and (ii) each Eurodollar Advance and
Discount Advance shall, upon the expiration of the interest period applicable
thereto, automatically be converted into a Federal Funds Advance and
reallocated among all Lenders in accordance with each Lender's Commitment
Percentage.  Each Lender holding less than its Commitment Percentage of all
Advances (excluding Bid Loans) shall at the times set forth for reallocations
in the preceding sentence immediately purchase for cash and at face value such
participations in the Notes held by other Lenders, and make such other
adjustments, as may be needed to cause each Lender to hold its Commitment
Percentage of the Advances hereunder (other than Bid Loans made by such
Lender).  Notwithstanding the preceding provisions of this Section 2.3(e) or
any other provision of this Agreement, no Lender shall be required to so
purchase such





                                      -35-
<PAGE>   42

participations to the extent that such purchase would cause such Lender's share
of the aggregate unpaid principal amount of all Loans (other than Bid Loans)
then outstanding under this Agreement to exceed its Commitment hereunder.


         2.4     Discount Advances.

                 (a)  Funding of Discount Loans.  Subject to the terms and
conditions herein (including the Lending Sublimits) and the terms and
conditions of any Balance Bank Agreement, the Company may request a Discount
Advance from any Balance Bank; provided that Discount Advances shall be made
only on the tenth day of each calendar month or, if such tenth day is not a
Business Day, on the next succeeding Business Day thereafter.

                 (b)  Discounted Advance.   Each Discount Loan made available
hereunder shall not bear interest but shall instead be funded to the Company at
a discount ("Balance Bank Discount") from the principal amount repayable by the
Company at the end of the applicable Discount Loan Period (the "Face Amount")
calculated to yield to the Balance Bank, when the Face Amount is repaid in full
at the end of the applicable Discount Loan Period, a per annum return on the
amount advanced equal to the Discount Rate for the applicable Discount Loan
Period.  The full Face Amount of each Discount Advance shall then be repaid by
the Company at the expiration of the applicable Discount Loan Period.
Accordingly, each Discount Advance shall bear no interest prior to the
expiration of the applicable Discount Loan Period.  The amount of the Discount
Advance actually disbursed to the Company on the Advance Date therefor (which
amount shall necessarily be less than the Face Amount) shall be equal to the
amount requested by the Company in the Advance Notice requesting such Discount
Advance, and the Face Amount shall be determined by the Agent based on the
Balance Bank Discount.  From and after the expiration of such Discount Loan
Period, each Discount Loan constituting a portion of such Discount Advance not
repaid shall bear interest on its Face Amount at the rate set forth in Section
2.7.

                 (c)  Balance Bank Agreement.  Discount Advances are based upon
the expectation that the Company will maintain average daily qualifying
balances with the applicable Balance Bank during the applicable Discount Loan
Period.  The Agent will collect and disburse the Discount Advances, but shall
not be obligated to





                                      -36-
<PAGE>   43

confirm any matters with respect to balances maintained with Balance Banks or
to collect any fees or amounts charged by Balance Banks with regard to such
balances.  Each Balance Bank shall with the Company's agreement impose its own
requirements upon the Company in dealing with deviations in actual balances
from projected balances.  All such matters shall be governed by separate
Balance Bank Agreements between each such Balance Bank and the Company, and the
Agent shall have no responsibility therefor.  No Discount Advance shall be
available from a particular Balance Bank until (i) the Company and such Balance
Bank have executed and delivered a Balance Bank Agreement and so advised the
Agent in writing, and (ii) in the case of a Non-Lender Balance Bank, such
Non-Lender Balance Bank shall have executed either this Agreement or a
Non-Lender Balance Bank Supplement in the form of Exhibit I hereto agreeing to
be bound by the terms of this Section 2.4.

                 (d)  Ratable Purchase by All Lenders.  A portion of each
Discount Advance (or, in the case of Non-Lender Balance Banks, the entire
Discount Advance made in accordance with the terms of this Agreement), shall be
sold simultaneously with the funding by the Balance Bank to the other Lenders
(each a "Purchasing Lender") on a pro rata basis in accordance with each such
Lender's Adjusted Commitment Percentage.  Each Purchasing Lender hereby agrees
to purchase and acquire, prior to funding, for cash at the Purchase Price and
without recourse to the Balance Bank, its Adjusted Commitment Percentage share
of such Discount Advance (as to each Purchasing Lender, such amount shall be a
Discount Loan by such Lender).  The purchase price ("Purchase Price") payable
by each Purchasing Lender shall be calculated to yield such Lender upon payment
at the end of the applicable Discount Loan Period of its Discount Loan a per
annum return on the Purchase Price equal to the Eurodollar Rate which would
have been applicable for a one month Eurodollar Interest Period ending on the
same date as such Discount Loan Period.  Each Balance Bank hereby irrevocably
agrees to sell and assign, without recourse, such portion of every Discount
Advance made by such Balance Bank (or, in the case of Non-Lender Balance Banks,
the entire amount of each such Discount Advance) to each Purchasing Lender at
the applicable Purchase Price.  Each Balance Bank (other than Non-Lender
Balance Banks) shall retain its Adjusted Commitment Percentage share of the
Face Amount of each Discount Advance, which shall constitute a Discount Loan
owing to the Balance Bank.





                                      -37-
<PAGE>   44

                 (e)  Minimum Amounts; Funding.  Each Discount Advance shall be
requested by the Company in accordance with Section 2.9.  On the Advance Date
for each such Discount Advance, subject to the other provisions hereof and upon
receipt by the Agent for the account of the Balance Bank from each of the
Purchasing Lenders of the aggregate Purchase Price required to be made
available by such Lenders, the Balance Bank will make the full Discount Advance
available to the Agent for the account of the Company in the manner specified
in Section 2.11.  On the Advance Date for each such Discount Advance, each
Purchasing Lender will make available to the Agent for the account of the
Balance Bank in immediately available funds an amount equal to the Purchase
Price for the share of such Discount Advance being purchased by such Lender
from the Balance Bank.

                 (f)  Consent to Assignment.  The Company hereby acknowledges
and consents to the assignment of Discount Loans by each Balance Bank to the
other Lenders, as contemplated by this Section 2.4.  The Company and the Agent
shall treat each Purchasing Lender with respect to its share of each Discount
Advance as if such share of such Discount Advance had originally been made by
such Purchasing Lender directly to the Company as a Discount Loan.

                 (g)  Discount Notes.  The Discount Loans owing to each Lender
shall be evidenced by a single master promissory note of the Company in the
full amount of such Lender's Commitment, substantially in the form of Exhibit
E-2 (a "Discount Note") executed and delivered prior to the initial Discount
Advance, payable to the order of such Lender and representing from time to time
the obligation of the Company to pay the aggregate Face Amount of all Discount
Loans then owed to such Lender.


         2.5     Swingline Advances.

                 (a)      In General.  Subject to the terms and conditions
herein, the Company and each Borrowing Subsidiary may request Swingline
Advances from the Swingline Lender on a non-pro rata basis, and such Swingline
Advance shall be funded to the Company or a Borrowing Subsidiary, as
applicable, by the Swingline Lender on the Advance Date therefor.  As set forth
in, but subject to the provisions of, Sections 2.3(d) and (e), Swingline
Advances shall be reallocated among the Lenders (i) automatically after the
occurrence of an Event of Default described in Section





                                      -38-
<PAGE>   45

10.1(k), (ii) upon the request of any Lender during the continuance of any
other Event of Default, and (iii) upon the election of the Swingline Lender
made at any time.

                 (b)  Swingline Buydown Advances.   Swingline Buydown Advances
are based upon the expectation that the Company will maintain average daily
qualifying balances with the Swingline Lender while any Swingline Buydown
Advance is outstanding.  The Swingline Lender shall with the Company's
agreement impose its own requirements upon the Company in dealing with
deviations in actual balances from projected balances.  All such matters shall
be governed by a Balance Bank Agreement between the Swingline Lender and the
Company.

                 (c)  Swingline Advances to Pay Amounts Due to Swingline
Lender.  If any amounts are advanced by the Swingline Lender to cover checks or
wire transfers from Company or Borrowing Subsidiary accounts maintained with
the Swingline Lender when there are insufficient funds in such accounts to
cover the applicable check or wire transfer and sufficient funds are not
deposited in the applicable account before the close of business on the day on
which the applicable check or wire transfer request is honored, then the
Company shall be deemed to have requested, and the Swingline Lender may (but
shall not be obligated to) elect to make, a Swingline Advance at the Alternate
Base Rate to pay such overdraft amount (even if such a Swingline Advance would
cause the aggregate amount of all outstanding Swingline Advances to exceed the
Swingline Commitment); provided however, that (i) the Swingline Lender shall
not make any such Swingline Advance to the extent such Advance would cause the
Credit Requirement to exceed the Borrowing Base, and (ii) the reallocations of
any such Swingline Advances among the Lenders shall be as set forth in, but
subject to the provisions of, Sections 2.3(d) and (e).


         2.6     Bid Loans, Approved GNMA Letters of Credit, and Approved Rate
Hedging Agreements.

                 (a)  Special Bids.  The Company may, at any time, solicit a
bid from any Lender on a non-pro rata basis for a loan (a "Bid Loan") in such
amount and accruing interest at such rate as may be bid to the Company by such
Lender for interest periods of 1 to 45 days.  Such Lender, in its sole
discretion, may make such a bid for a Bid Loan.  The Company will be under no
obligation to accept any such bid, but may accept any one, or





                                      -39-

more than one, of such bids.  A Lender whose bid has been accepted by the
Company shall be referred to as a "Bid Lender".  The Company and each Bid
Lender shall execute and submit a Bid Loan Notice in the form of Exhibit G
hereto to the Agent concurrently with the Advance Notice for such Bid Loan.

                 (b)  Approved GNMA Letters of Credit.  The Company may, at any
time, request that any Lender issue a letter of credit in favor of GNMA as a
result of the failure by the Company or any Borrowing Subsidiary to satisfy all
document submission requirements of GNMA in connection with the certification
or re-certification by GNMA of a pool of Mortgage Loans.  If a Lender agrees to
issue such a letter of credit and desires that such letter of credit be ratably
secured (along with the other Credit Indebtedness) by the Collateral, such
Lender shall submit to the Agent a copy of the proposed letter of credit and
copies of any related reimbursement agreement or other related documentation.
If (i) the Agent approves such letter of credit and other documentation (which
approval shall not be unreasonably withheld), and (ii) the letter of credit
expires by its terms on a date which is prior to the Termination Date, then
such letter of credit shall constitute an Approved GNMA Letter of Credit and
such Lender shall constitute an "Issuing Lender".  No such letter of credit
shall be considered an Approved GNMA Letter of Credit if its inclusion as an
Approved GNMA Letter of Credit would, at the time of issuance, cause any
Lending Sublimit to be exceeded.  The Company and the applicable Issuing Lender
shall promptly notify the Agent upon (i) the expiration, cancellation or
honoring of any Approved GNMA Letter of Credit, and (ii) the payment by the
Company or the applicable Borrowing Subsidiary of any amounts due to the
Issuing Lender in respect of any Approved GNMA Letter of Credit Obligations.
No Issuing Lender nor the Company shall amend or renew any Approved GNMA Letter
of Credit or any related reimbursement agreement or other related document
without the prior written consent of the Agent (which consent shall not be
unreasonably withheld).

                 (c)  Approved Rate Hedging Agreements.  The Company may, from
time to time, request that one or more Lenders enter into Rate Hedging
Agreements with the Company.  If a Lender agrees to enter into such an
agreement and desires all or a portion of the Company's obligations thereunder
to be ratably secured by the Collateral, such Lender shall submit to the Agent
a copy of the proposed Rate Hedging Agreement and copies of any related





                                      -40-
<PAGE>   47

documentation.  If (i) the Agent approves such Rate Hedging Agreement, (ii)
such Rate Hedging Agreement terminates automatically on or before the
Termination Date or provides for the release of the Collateral (or the transfer
or liquidation of Collateral in the amount of the Approved Secured Rate Hedging
Obligations) at such time, and (iii) such Rate Hedging Agreement specifies the
maximum amount of obligations thereunder that will be secured by the
Collateral, then such Rate Hedging Agreement shall be an Approved Rate Hedging
Agreement and the obligations thereunder, up to the stated maximum, shall be
Approved Secured Rate Hedging Obligations hereunder, subject to the limitation
that the maximum aggregate Approved Secured Rate Hedging Obligations at any
time shall not exceed $25,000,000.

                 (d)  Additional Commitment.  Each Bid Lender's commitment
under an accepted special bid, each Issuing Lender's issuance of an Approved
GNMA Letter of Credit and each Rate Hedging Agreement entered into by a Lender
shall be in addition to such Lender's Commitment and shall not reduce such
Lender's obligation to continue to fund its Adjusted Commitment Percentage of
any other Advance.

                 (e)  Notes.  Each Bid Loan owing to each Bid Lender shall not
be evidenced by the Notes executed and delivered in the form of Exhibit E-1 and
E-2, but shall instead be evidenced by an additional promissory note or notes
in a form mutually agreed to by the Company and such Bid Lender.  The Agent
shall have no responsibility to confirm the existence or substance of such
additional promissory notes.


         2.7     Rate after Maturity.

                 Any Advance not paid at maturity, whether by acceleration or
otherwise, and any other amount not paid when due hereunder shall bear interest
until paid in full at a rate per annum equal to the Alternate Base Rate plus
two percent (2.0%) per annum; provided, however, that such interest rate after
maturity shall in no event be less than the interest rate that was in effect
with respect to such Advance prior to maturity.


         2.8     Interest Payment Dates.

                 Interest shall accrue at the relevant rate for each day from
the day on which the proceeds of such Advance are made





                                      -41-
<PAGE>   48

available to the Company or a Borrowing Subsidiary.  Interest accrued on each
Advance other than a Eurodollar Advance, a Discount Loan (which does not accrue
interest prior to maturity), or a Bid Loan shall be payable on the first to
occur of (i) the first Business Day of the immediately following calendar
month, commencing with the first such date to occur after the date hereof, or
(ii) at maturity of the Facility, whether due to acceleration or otherwise.
Interest accrued on each Eurodollar Advance shall be payable on the first to
occur of (i) the last day of each Eurodollar Interest Period, or (ii) any date
on which any such Eurodollar Advance is prepaid, whether due to acceleration or
otherwise, or (iii) the Termination Date.   Interest on Bid Loans shall be
payable on the first to occur of (i) the last day of the applicable interest
period for such Bid Loan as set forth in the Bid Loan Notice, (ii) any date on
which such Bid Loan is prepaid whether due to acceleration or otherwise or
(iii) the Termination Date.  Interest and Fees shall be calculated for actual
days elapsed on the basis of a 360-day year.  Interest shall be payable for the
day an Advance is made.  Interest shall not be payable for the day of any
payment on the amount paid if payment is received prior to noon (Chicago time)
at the place of payment.  If any payment of principal of or interest on an
Advance shall become due on a day which is not a Business Day, such payment
shall be made on the next succeeding Business Day and, in the case of a
principal payment, such extension of time shall be included in computing
interest in connection with such payment.


         2.9     Method of Selecting Rate Options and Interest Periods.

                 Subject to the terms hereof, for each Advance hereunder the
Company (or a Borrowing Subsidiary or the Company on behalf of a Borrowing
Subsidiary in the case of Swingline Advances to be borrowed by a Borrowing
Subsidiary) shall give the Agent irrevocable notice (an "Advance Notice") not
later than (i) 10:00 a.m. (Chicago time) on the proposed Advance Date for each
Bid Loan or Federal Funds Advance, (ii) noon (Chicago time) on the proposed
Advance Date for each Alternate Base Rate Advance (other than Swingline
Advances), (iii) 3:00 p.m.  (Chicago time) on the proposed Advance Date for
each Overnight Transaction Advance, (iv) 4:00 p.m. (Chicago time) on the
proposed Advance Date for each Swingline Advance which is an Alternate Base
Rate Advance or a Swingline Buydown Advance, and (v) 11:00 a.m. (Chicago time)





                                      -42-
<PAGE>   49

three (3) Business Days before the Advance Date for each Eurodollar Advance and
each Discount Advance, specifying:

                 (a)      the Advance Date, which shall be a Business Day, of
                          such Advance,

                 (b)      the aggregate amount of such Advance, which shall be
                          in an amount equal to $5,000,000 or a whole multiple
                          of $1,000,000 in excess thereof, except that (i)
                          Swingline Advances other than Overnight Transaction
                          Advances shall have no minimum amount and need not be
                          in multiples of $1,000,000, and (ii) Overnight
                          Transaction Advances shall be in a minimum amount
                          equal to $100,000 but need not be in multiples of
                          $1,000,000.

                 (c)      the type of such Advance,

                 (d)      the interest period applicable to such Advance, if
                          applicable,

                 (e)      if such Advance is a Discount Advance, the Balance
                          Bank or Balance Banks for such Advance and, if
                          applicable, the portion of such Discount Advance
                          allocated to each such Balance Bank,

                 (f)      if such Advance is a Bid Loan, the Bid Lender for
                          such Bid Loan,

                 (g)      if such Advance is a Swingline Advance, which entity
                          (i.e. the Company or a particular Borrowing
                          Subsidiary) is the borrower of such Advance, and

                 (h)      what portion, if any, of such Advance is to be used
                          solely for the purpose of repaying maturing 
                          commercial paper.

Notwithstanding the foregoing, the Agent may also agree, in its sole
discretion, to accept (A) an Advance Notice requesting a Swingline Advance
which is an Alternate Base Rate Advance or Swingline Buydown Advance or (B) a
Bid Loan Notice at any time up until the close of the Agent's business day.
Delivery of an Advance Notice, whether by telephone or in writing, shall
constitute a representation and warranty that, after giving





                                      -43-
<PAGE>   50

effect to the amount of the Advance being requested, (i) the then-current
Borrowing Base is equal to or greater than the Credit Requirement, and (ii) no
Lending Sublimit shall be exceeded.  Changes in the rate of interest on that
portion of any Advance maintained as an Alternate Base Rate Advance will take
effect simultaneously with each change in the Alternate Base Rate.  The
interest rate on each Overnight Transaction Advance or Federal Funds Advance
shall be recalculated daily for each day that such Overnight Transaction
Advance or Federal Funds Advance is continued under Section 2.12(ii).  Each
Eurodollar Advance shall bear interest for each day from and including the
first day of the Eurodollar Interest Period applicable thereto to (but not
including) the last day of such Eurodollar Interest Period at the interest rate
determined as applicable to such Advance.  The Company shall select Eurodollar
Interest Periods and Discount Loan Periods with respect to Eurodollar Advances
and Discount Loans so that it is not necessary to pay a Eurodollar Advance or
Discount Loan prior to the last day of the applicable Eurodollar Interest
Period or Discount Loan Period, as the case may be, in order to make the
mandatory repayment on the Termination Date.  Any change in the Applicable
Margin shall be effective immediately with respect to the interest rates on any
Loans outstanding other than Discount Loans.  Changes in the Applicable Margin
relating to Discount Loans shall not affect Discount Loans outstanding at the
time of any such change but shall be effective with respect to any Discount
Loans made after the date of any such change.


         2.10    Maximum Number of Eurodollar Loans.

                 The Company may not request an additional Eurodollar Advance
if the making of such Advance would result in any Lender holding Eurodollar
Loans having more than six (6) different Eurodollar Interest Periods at any
given time.


         2.11    Funding Procedures.

                 Not later than 2:00 p.m. (Chicago time) on each Advance Date,
each Lender shall make available its Loan or Loans (including Bid Loans), in
funds immediately available in Chicago to the Agent at its address specified
pursuant to Article XII, provided that Swingline Advances may be funded at any
time up to (i) the close of the Swingline Lender's business day so long as
First Chicago is both the Agent and the sole Swingline Lender, or





                                      -44-
<PAGE>   51

(ii) 4:00 p.m. (Chicago time) if First Chicago is not both the Agent and the
sole Swingline Lender.  The Agent will make the funds so received from the
Lenders available to the Company or a Borrowing Subsidiary, as applicable, at
the Agent's aforesaid address, subject to the provisions of Article V.
Notwithstanding the foregoing, the Agent may also agree, in its sole
discretion, to accept delivery of Bid Loan funds and to make such funds
available to the Company at any time up to the close of the Agent's business
day.


         2.12    Conversion and Continuation.

                      (i)   The Company may elect from time to time, subject to
         the provisions of Sections 2.3(a), 2.9 and 2.10 and the Lending
         Sublimits to convert all or any part of any Advance (other than a Bid
         Loan or Discount Advance) into a different type of Advance, provided
         that any conversion of any such Eurodollar Advance shall be made on,
         and only on, the last day of the applicable Eurodollar Interest
         Period.  Discount Advances and Bid Loans are payable on the last day
         of the applicable Discount Loan Period or Bid Loan period and may be
         repaid out of new Advances hereunder but may not be converted directly
         to a different type of Advance.

                      (ii)  Alternate Base Rate Advances shall continue as the
         same type of Advances unless and until such Advances are converted
         into a different form of Advance in accordance with the terms hereof.
         Federal Funds Advances shall continue as Federal Funds Advances unless
         and until (a) such Advances are converted into a different form of
         Advance in accordance with the terms hereof or (b) the Company has
         paid any such Federal Funds Advance prior to 10:00 a.m. (Chicago time)
         on any Business Day or given the Agent written notice before 10:00
         a.m. (Chicago time) on any Business Day that such Federal Funds
         Advance will be repaid on such Business Day.  Overnight Transaction
         Advances and Swingline Buydown Advances shall continue as Overnight
         Transaction Advances and Swingline Buydown Advances, respectively,
         unless and until (a) such Advances are converted into a different form
         of Advance in accordance with the terms hereof or (b) the Company or a
         Borrowing Subsidiary, as applicable, has paid any such Overnight
         Transaction Advance or Swingline Buydown Advance prior to 3:00 p.m.
         (Chicago time) on any Business Day or given the Agent written notice
         before 3:00 p.m. (Chicago





                                      -45-
<PAGE>   52

         time) on any Business Day that such Overnight Transaction Advance or
         Swingline Buydown Advance will be repaid on such Business Day.  If the
         Company so notifies the Agent that it will be paying a Federal Funds
         Advance, Overnight Transaction Advance or Swingline Buydown Advance on
         any Business Day and fails to do so, such Advance shall be converted
         into an Alternate Base Rate Advance.  Eurodollar Advances shall
         continue until the end of the then-applicable Eurodollar Interest
         Period therefor, at which time each such Advance shall be
         automatically converted to a Federal Funds Advance, unless the Company
         shall have given the Agent notice in accordance with Section 2.12(iii)
         requesting that, at the end of such Eurodollar Interest Period, such
         Advance continue as a Eurodollar Advance for a specified Eurodollar
         Interest Period or be converted to a different type of Advance.

                    (iii)   The Company shall give the Agent irrevocable notice
         (a "Conversion/Continuation Notice") of each conversion of an
         Alternate Base Rate Advance, a Federal Funds Advance, a Swingline
         Buydown Advance or an Overnight Transaction Advance or conversion or
         continuation of a Eurodollar Advance not later than (i) 10:00 a.m.
         (Chicago time) on the date of the requested conversion or
         continuation, in the case of a conversion into a Federal Funds
         Advance, Alternate Base Rate Advance, Overnight Transaction Advance or
         Swingline Buydown Advance, or (ii) 11:00 a.m. (Chicago time) at least
         three Business Days prior to the date of the requested conversion into
         or continuation of a Eurodollar Loan, specifying:  (1) the requested
         date (which shall be a Business Day) of such conversion or
         continuation; (2) the amount and type of the Advance to be converted
         or continued; (3) the amount and type(s) of Advance(s) into which such
         Advance is to be converted or continued; and (4) in the case of a
         conversion into or continuation of a Eurodollar Advance, the duration
         of the Eurodollar Interest Period applicable thereto.


         2.13    Optional Principal Payments.

                 All or any portion of Alternate Base Rate Advances, Overnight
Transaction Advances, Swingline Buydown Advances and Federal Funds Advances may
be paid without penalty or premium on any Business Day provided that such
repayments are made by (i) 10:00 a.m. (Chicago time) with respect to Federal
Funds Advances,





                                      -46-
<PAGE>   53

(ii) noon (Chicago time) with respect to Alternate Base Rate Advances, or (iii)
3:00 p.m. (Chicago time) with respect to Overnight Transaction Advances and
Swingline Buydown Advances.  A Eurodollar Advance or Discount Loan may not be
paid prior to the last day of the applicable Eurodollar Interest Period or
Discount Loan Period, as the case may be; provided, however, that the Company
shall compensate the Lenders for any funding losses and/or loss of profits
incurred as a result of any voluntary prepayment (if accepted) or involuntary
prepayment of any such Advance prior to the last day of the applicable
Eurodollar Interest Period or Discount Loan Period.    Bid Loans may not be
prepaid unless the applicable Bid Lender has agreed otherwise and notified the
Agent of such agreement.  All optional principal payments shall be applied to
the type of Advance designated by the Company when making such payment,
provided that any payments received during the continuance of an Event of
Default shall be applied on a pro rata basis to all Advances then outstanding
(with the portion applicable to Eurodollar Loans or Discount Loans to be
applied to such Loans either immediately or at the end of the relevant
Eurodollar Interest Period or Discount Loan Period at the option of the
Company).


         2.14    Required Principal Payments.

                 (a)      Payments Related to Borrowing Base.  On any date that
the Credit Requirement is in excess of the then-current Borrowing Base, the
Company shall make a mandatory payment to the Agent for the benefit of the
Lenders in the amount of such excess.  Such payment shall be allocated pro rata
among the Lenders in accordance with the amounts of their outstanding Loans
hereunder.

                 (b)      Final Payment on Termination Date.  The outstanding
principal balance of all Advances not repaid earlier, together with any accrued
and unpaid interest and Fees, unless required to be paid earlier pursuant to
the terms hereof, shall be due and payable on the Termination Date.


         2.15    Method of Payment.

                 All payments of principal, interest, and Fees hereunder
(including any payments related to Bid Loans) shall be made in immediately
available funds to the Agent at the Agent's address specified pursuant to
Article XII, or at any other Lending





                                      -47-
<PAGE>   54

Installation of the Agent specified in writing by the Agent to the Company on
the date due by 1:00 p.m. (Chicago time) with respect to all Advances other
than Swingline Advances and by 3:00 p.m. (Chicago time) with respect to
Swingline Advances.  Notwithstanding the foregoing, if the Company or a
Borrowing Subsidiary fails to repay or give the Agent notice of repayment of a
Federal Funds Advance before 10:00 a.m.  (Chicago time) or an Overnight
Transaction Advance before 3:00 p.m. (Chicago time) on the Business Day that
the Company or the Borrowing Subsidiary intends to repay such Advance, any
payment of such Advance received by the Agent on such Business Day after the
time required for payment or notice shall be deemed to have been received by
the Agent at the opening of business on the following Business Day.  Each
payment delivered to the Agent for the account of any Lender shall be delivered
promptly by the Agent to such Lender in the same type of funds which the Agent
received at its address specified pursuant to Article XII or at any Lending
Installation specified in a notice received by the Agent from such Lender.  The
Agent is hereby authorized to charge the account of the Company maintained with
First Chicago for each payment of principal, interest and fees as it becomes
due hereunder.


         2.16    Notes; Telephonic Notices.

                 Each Lender is hereby authorized to record the principal
amount of each of its Loans and each repayment on the schedules attached to its
Notes provided, however, that the failure to so record or any error in such
recording shall not affect the Company's or any Borrowing Subsidiary's
obligations hereunder or under such Notes.  The Company and each Borrowing
Subsidiary each hereby authorizes the Lenders and the Agent to extend, continue
or convert Advances, effect Rate Option selections and to transfer funds to or
for the account of the Company or the applicable Borrowing Subsidiary based on
telephonic notices (confirmed promptly thereafter by facsimile) made by any
person or persons the Agent or any Lender in good faith believes to be acting
on behalf of the Company or the applicable Borrowing Subsidiary.  The Company
and each Borrowing Subsidiary each agrees to deliver promptly to the Agent a
written confirmation, if such confirmation is requested by the Agent or any
Lender, of each telephonic notice signed by an officer of the Company or the
Borrowing Subsidiary, as applicable, authorized in writing to do so.  If the
written confirmation differs in any material respect





                                      -48-
<PAGE>   55

from the action taken by the Agent and the Lenders, the records of the Agent
and the Lenders shall govern absent manifest error.


         2.17    General Provisions as to Payments.

                 (a)      The Company (or the applicable Borrowing Subsidiary
         with respect to Loans borrowed by a Borrowing Subsidiary) shall make
         each payment of principal or interest on the Loans and shall pay all
         Fees not later than the times stated in Section 2.15.  The Agent shall
         promptly distribute to each Lender its share of each payment of
         principal or interest or fees received by the Agent for the account of
         such Lender.

                 (b)      Amounts paid to or held by the Agent for the payment
         of Loans shall not be deemed paid to a Lender until received by such
         Lender by the later of 3:00 p.m. (Chicago time) or the close of
         business on such date.  If amounts are received by the Agent from the
         Company or a Borrowing Subsidiary prior to the applicable times stated
         in Section 2.15 and the Agent fails to make a Lender's portion of such
         amount available to such Lender by close of business on such date,
         neither the Company nor such Borrowing Subsidiary shall have any
         obligation to pay any further interest on such payment and the Agent
         shall pay to such Lender interest on such payment to the date paid to
         such Lender by the Agent at a rate per annum equal to the then-current
         Published Federal Funds Effective Rate.


         2.18    Notification of Advances, Interest Rates and Prepayments.

                 Promptly after receipt thereof, the Agent will notify each
Lender by facsimile of the contents of each Advance Notice,
Conversion/Continuation Notice, and repayment notice received by it hereunder.
Not later than one Business Day prior to the Advance Date for each Eurodollar
Advance or Discount Loan, the Agent will notify by facsimile each Lender and
the Company of the interest rate applicable to each Eurodollar Advance, the
Face Amount of each Discount Advance and the Purchase Price to be paid by each
Lender for its share of such Discount Advance promptly upon determination of
such interest rate, Face Amount and Purchase Price.  When any Advances are
outstanding or have been requested at the Federal Funds Rate or the Alternate
Base Rate





                                      -49-
<PAGE>   56

the Agent will give each Lender and the Company prompt notice by facsimile of
each change in such rate.


         2.19    Lending Installations.

                 Each Lender may book its Loans at any Lending Installation
selected by such Lender and may change its Lending Installation from time to
time.  All terms of this Agreement shall apply to any such Lending Installation
and the Notes shall be deemed held by each Lender for the benefit of such
Lending Installation.  Each Lender may, by facsimile or written notice to the
Agent and the Company, designate a Lending Installation through which Loans
will be made by it and for whose account Loan payments are to be made.
Notwithstanding the foregoing, no Lender may transfer its Loans to another
Lending Installation if such transfer would cause the Company to incur
additional indemnification costs under Section 3.1 hereof, and if after a
Lender transfers its Loans to another Lending Installation the Company incurs
additional indemnification costs under Section 3.1 hereof as a result of such
transfer, such Loans shall be transferred back to the original Lending
Installation.


         2.20    Non-Receipt of Funds by Agent.

                 (a)  Unless the Company, a Borrowing Subsidiary or a Lender,
as the case may be, notifies the Agent prior to the close of business on the
Business Day immediately preceding the date on which it is required to make
payment to the Agent of (i) in the case of a Lender, the proceeds of a Loan or
(ii) in the case of the Company or a Borrowing Subsidiary, a payment of
principal, interest or fees to the Agent for the account of the Lenders, that
it does not intend to make such payment, the Agent may assume that such payment
has been made or will be made on the date required.  The Agent may, but shall
not be obligated to, make the amount of such payment available to the intended
recipient in reliance upon such assumption.  If such Lender, the Company or the
Borrowing Subsidiary, as the case may be, has not in fact made or does not make
when due such payment to the Agent, the recipient of such payment shall, on
demand by the Agent, repay to the Agent the amount so made available together
with interest thereon in respect of each day during the period commencing on
the date such amount was so made available by the Agent until the date the
Agent recovers such amount at a rate per annum equal to (i) in the case of
repayment by a Lender, the





                                      -50-

Published Federal Funds Effective Rate for such day or (ii) in the case of
repayment by the Company or a Borrowing Subsidiary, the interest rate
applicable to the relevant Loan.  If a Lender fails to pay the Agent as
provided in the preceding sentence, the Company shall pay such amount to the
Agent upon demand plus interest (at the rate applicable to the applicable
Advance) to the date of repayment (but not including such date if payment is
received prior to the deadlines established in Section 2.15).

                 (b)      Neither the Agent nor any Lender shall incur any
liability to the Company or any Borrowing Subsidiary in acting upon any
telephonic notice referred to in this Agreement which the Agent or such Lender
believes in good faith to have been given by a duly authorized officer or other
person authorized to borrow on behalf of Company or the Borrowing Subsidiary or
for otherwise acting in good faith under this Section 2.20.  Upon the funding
of Loans by the Lenders in accordance with this Agreement (including
satisfaction of all conditions thereto) pursuant to any telephonic notice (with
confirmation promptly thereafter by facsimile), the Company (or the applicable
Borrowing Subsidiary with respect to Advances borrowed by a Borrowing
Subsidiary) shall have effected a borrowing hereunder.  An Advance Notice (or
telephonic notice in lieu thereof) shall be irrevocable and the Company or the
Borrowing Subsidiary, as applicable, shall be bound to effect a borrowing in
accordance therewith.

                 (c)      If the Agent fails to make any Loan funds received
from a Lender available to the Company for any reason and does not return such
Loan funds to such Lender on the same Business Day such funds were received by
the Agent, the Agent shall pay to such Lender, upon demand, interest from the
date such funds are received by the Agent from such Lender, provided such funds
were received prior to the deadlines for receipt set forth in Section 2.11
until the date such corresponding amount is either made available by the Agent
to the Company within the time limits of Section 2.11 or so returned to such
Lender, at the rate per annum equal to the then-current Published Federal Funds
Effective Rate and the Company shall have no responsibility to such Lender with
respect to such funds until they are so made available to the Company by the
Agent.

                 (d)      Nothing in this Section 2.20 shall relieve any Lender
from its obligation to fund its share of any Advance, prejudice any rights the
Company may have against any Lender as a





                                      -51-

result of such Lender's failure to make the amount of its Loan available to the
Company or obligate any Lender to fund any other Lender's share of any Advance.


                                  ARTICLE III
                            CHANGE IN CIRCUMSTANCES


         3.1     Yield Protection.

                 If, after the date of this Agreement, the adoption of any law
or any governmental or quasi-governmental rule, regulation, policy, guideline
or directive (whether or not having the force of law), or any change in any
existing or future law, rule, regulation, policy, guideline or directive or the
interpretation or administration thereof, or the compliance of any Lender
therewith,

                      (i)   subjects any Lender or any applicable Lending
         Installation to any tax, duty, charge or withholding on or from
         payments due from the Company or any Borrowing Subsidiary, or changes
         the basis of taxation of payments to any Lender in respect of its
         Loans or other amounts due it hereunder (excluding any tax imposed
         with respect to the overall net income of any Lender or its Lending
         Installation, any franchise taxes imposed on any such Lender or
         Lending Installation to the extent such franchise taxes are in lieu of
         net income taxes), or

                      (ii)  imposes or increases or deems applicable any
         reserve, assessment, insurance charge, special deposit or similar
         requirement against assets of, deposits with or for the account of, or
         credit extended by, any Lender or any applicable Lending Installation
         (other than reserves and assessments taken into account in determining
         the interest rate applicable to Eurodollar Advances or Discount
         Loans), or

                    (iii)   affects the amount of capital required or expected
         to be maintained by any Lender or Lending Installation or any
         corporation controlling any Lender or Lending Installation and such
         Lender determines the amount of capital required is increased by or
         based upon the existence of this Agreement or its obligation to make
         or maintain Loans hereunder or of commitments of this type, or





                                      -52-
<PAGE>   59

                      (iv)  imposes any other condition which requires any
         Lender or any applicable Lending Installation to make any payment
         calculated by reference to the amount of loans held or interest
         received by it in an amount deemed material by such Lender,

and the result of any of the foregoing is to increase the cost to such Lender
or Lending Installation of making, renewing or maintaining its Commitment or
any Loan or to reduce any amount receivable in respect thereof or to reduce the
rate of return on the capital of such Lender or Lending Installation or any
Person controlling such Lender or Lending Installation as it relates to credit
facilities in the nature of that evidenced by this Agreement, then the Company
shall pay such Lender that portion of such increased expense incurred
(including, in the case of Section 3.1(iii), any reduction in the rate of
return on capital to an amount below that which it could have achieved but for
such law, rule, regulation, policy, guideline or directive and after taking
into account such Lender's policies as to capital adequacy) or reduction in an
amount received which such Lender determines is attributable to making, funding
and maintaining its Loans and its Commitment to the extent such expenses or
reductions arise from and after the date which is 90 days before receipt by the
Company of demand for payment by such Lender.  Notwithstanding the foregoing,
if any of the foregoing circumstances otherwise giving rise to the yield
protection provisions of this Section are imposed solely against a single
Lender as a result of circumstances or conditions which apply solely to that
Lender and not generally to lenders domiciled in the jurisdiction of such
Lender's domicile, then the yield protection provisions of this Section shall
not apply with respect to such circumstances.


         3.2     Availability of Rate Options.

                 If any Lender determines that maintenance of any of its
Eurodollar Loans or Discount Loans at a suitable Lending Installation would
violate any applicable law, rule, regulation or directive, whether or not
having the force of law, the Agent shall suspend the availability of the
affected Rate Option and require any Eurodollar Advances or Discount Loans
outstanding at the affected Rate Option to be repaid immediately upon demand;
or if the Required Lenders determine that deposits of a type or maturity
appropriate to match fund Eurodollar Advances or





                                      -53-
<PAGE>   60

Discount Loans are not available, the Agent shall suspend the availability of
the affected Rate Option with respect to any such Loans or Advances made after
the date of any such determination.  If the Required Lenders determine that the
Eurodollar Rate or the Discount Rate does not accurately reflect the cost of
making a Eurodollar Advance or Discount Loan at such Rate Option, then, if for
any reason whatsoever the provisions of Section 3.1 are inapplicable, the Agent
shall suspend the availability of the affected Rate Option with respect to any
Eurodollar Advance or Discount Loan made after the date of any such
determination.


         3.3     Funding Indemnification.

                 If any payment of a Eurodollar Advance or Discount Loan occurs
on a date which is not the last day of the applicable Eurodollar Interest
Period or Discount Loan Period, whether because of acceleration, prepayment or
otherwise, or if a Eurodollar Advance, Overnight Transaction Advance, Federal
Funds Advance, Swingline Buydown Advance or Discount Loan is not made,
continued or established by conversion on the date specified by the Company or
a Borrowing Subsidiary for any reason other than default by the Lenders, the
Company will indemnify each Lender for any loss or cost incurred by it
resulting therefrom, including, without limitation, any loss or cost in
liquidating or employing deposits acquired to fund or maintain such Eurodollar
Advance or Discount Loan.


         3.4     Lender Statements; Survival of Indemnity.

                 To the extent reasonably possible, each Lender shall designate
an alternate Lending Installation with respect to its Eurodollar Advances and
Discount Loans to reduce any liability of the Company to such Lender under
Section 3.1 or to avoid the unavailability of a Rate Option under Section 3.2,
so long as such designation is not to the economic detriment of such Lender and
does not impose any increased regulatory burdens on such Lender.  Each Lender
shall deliver to the Agent and the Company a written statement of such Lender
as to the amount due, if any, under Section 3.1 or 3.3.  Such written statement
shall set forth in reasonable detail the calculations upon which such Lender
determined such amount and shall be final, conclusive and binding on the
Company in the absence of manifest error.  Determination of amounts payable
under such Sections in connection with a Eurodollar Advance or Discount Loan
shall be calculated as though





                                      -54-
<PAGE>   61

each Lender funded its related Loan through the purchase of a deposit of the
type and maturity corresponding to the deposit used as a reference in
determining the Eurodollar Rate or Discount Rate applicable to such Loan,
whether in fact that is the case or not.  The amount specified in the written
statement shall be payable within 15 days after receipt by the Company of the
written statement.  The obligations of the Company under Sections 3.1 and 3.3
shall survive payment of the Obligations and termination of this Agreement.  In
the event any Lender is affected by any of the events described in Section 3.1
or 3.2 the Company shall have the right, if no Default then exists, to repay in
full all Credit Indebtedness owed to such Lender provided that the Company has,
with the approval of the Agent (not to be unreasonably withheld), arranged to
substitute a replacement lender for the full amount of such Lender's
Commitment.


         3.5     Lender Tax Agreement.

                 Each Lender that is not incorporated under the laws of the
United States of America or a state thereof shall:

                   (i)  deliver to the Company and the Agent (A) two duly
         completed copies of the United States Internal Revenue Service Form
         1001 or 4224, or successor applicable form, as the case may be, and
         (B) an Internal Revenue Service Form W-8 or W-9, or successor
         applicable form, as the case may be;

                  (ii)  deliver to the Company and the Agent two further copies
         of any such form or certification on or before the date that any such
         form or certification expires or becomes obsolete and after the
         occurrence of any event requiring a change in the most recent form
         previously delivered by it to the Company; and

                 (iii)  obtain such extension of time for filing and complete
         such forms or certifications as may reasonably be requested by the
         Company or the Agent;

unless in any such case an event (including, without limitation, any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms or any
certifications required hereby inapplicable or which would prevent such Lender
from duly completing and delivering any such form or making such





                                      -55-
<PAGE>   62

certification with respect to it and such Lender so advises the Company and the
Agent.  Such Lender shall certify (i) in the case of Form 1001 or 4224
delivered in accordance with this Section 3.5, that it is entitled to receive
payments under this Agreement without deduction or withholding of any United
States federal income taxes and (ii) in the case of a Form W-8 or W-9, that it
is entitled to an exemption from United States backup withholding tax.  Each
Person that shall become a Lender or a Participant pursuant to Article XI
shall, upon the effectiveness of the related transfer, be required to provide
all of the forms and statements required pursuant to this Section, provided
that in the case of a Participant such Participant shall also furnish all such
required forms and statements to the Lender from which the related
participation shall have been purchased as well as to the Company and the
Agent.


                                   ARTICLE IV

Receivable claimed by the Servicing Purchaser (to the extent not already
deducted from Eligible Servicing Sale Receivables pursuant to the preceding
provisions) shall, at the election of the Agent, the Collateral Agent or the
Required Lenders, reduce the amount of such Servicing Sale Receivable which
qualifies as an Eligible Servicing Sale Receivable, with such reduction to be
effective immediately unless the Company in good faith contests the amount or
validity of such offset or reduction, and with such reduction to be effective
30 days after the claim of offset or reduction with respect to any amount which
is contested in good faith by the Company.

         powers and benefits of the Pledgor as mortgagee.

                 (9)  So long as the Collateral Agent complies with the
         procedures set forth in the Security Agreement relating to possession

                 (11)  To the extent that any applicable requirements of any
         law or any governmental rule, regulation, policy, guideline or

         interpretation thereof, including, without limitation, the provisions
         of Title XI of the Financial Institutions Reform, Recovery and
         Enforcement Act of 1989, as amended, reformed or otherwise modified
         from time to time, and any rules promulgated to implement such
         provisions (collectively, "Appraisal Regulations") require Pledgor to

         appraisal has been be obtained and such appraisal meets the
         requirements of all such Appraisal Regulations.

         such premises is located, (ii) are in full force and effect, and (iii)
         afford insurance against fire and such other risks as are usually
         insured against in the broad form of extended coverage insurance from
         time to time available, as well as insurance against flood hazards as
         required by FHA or VA.

                 (13)  To the best of the Pledgor's knowledge without
         investigation, no Person has transported, released, emitted,
         discharged, leached, dumped or disposed of any Hazardous Substance
         onto or into any portion of the premises encumbered by a Pledged
         Mortgage except in material compliance with all applicable federal,
         state, foreign and local laws, rules, regulations and orders.

                 (14)  If a Borrowing Subsidiary is the Pledgor, the Pledged
         Item was funded by the Company and is shown on the Company's (rather
         than the Borrowing Subsidiary's) balance sheet pursuant to the Funding
         Agreement.

         By pledging any Repurchased Agency Loans and Receivables to the
Collateral Agent under the Security Agreement the Company





                                      -67-

         as Eligible Collateral) which it has on the date hereof or become
         ineligible as a FHA-Approved Mortgagee, FHLMC-Approved Lender,

         perfected first priority security interest in the Collateral in favor
         of the Secured Parties and to create, maintain and preserve the
         security and benefits intended to be afforded by this Agreement and
         the Security Agreement, subject to no prior or equal security
         interest, lien, charge or encumbrance, or agreement purporting to
         grant to any Person a security interest in the Collateral (provided,
         however, that unless an Event of Default is continuing or the Required
         Lenders have requested otherwise, consents to assignments of options,
         futures

         contracts or other interest rate protection products in favor of the
         Lenders from the counterparties thereto shall not be required to be
         obtained).

                 (n)      With respect to Repurchased Agency Loans and
         Receivables, upon the request of the Collateral Agent or Agent the
         Company shall have executed and provided any and all documentation
         required by the Collateral Agent or Agent (including, but not limited
         to, all Required Mortgage Documents, the insurance or guaranty
         certificate applicable to such Mortgage Loan, and evidence
         satisfactory to the Collateral Agent and Agent of the amounts advanced
         by the Company in connection with such Mortgage Loan) to perfect the
         Lenders' security interest in such Repurchased Agency Loans and
         Receivables.

                 (o)      Upon the request of the Required Lenders, the Company
         and each Borrowing Subsidiary agree that the Company and each
         Borrowing Subsidiary shall require the closing agents for AP Mortgages
         to enter into escrow or other agreements regarding the monies used to
         fund such AP Mortgages.


         4.8     Release of Collateral.

                 In addition to the releases of Collateral provided for in
Sections 7(a)-(e) of the Security Agreement, upon the request of the Company
delivered from time to time to the Agent and the Collateral Agent, the Agent
shall authorize the Collateral Agent to release Collateral specified in such
notice from the lien of this Agreement, if, but only if, (i) at the time of
such release no Event of Default exists and no notice of a Default has been
issued that has not been cured, and (ii) any payment under Section 2.14(a)
which may be required (based on information relating to the Borrowing Base
supplied to the Agent by the Collateral Agent) as a result of such release has
been made (or contemporaneously with such release shall be made) so that the
release of such Collateral will not create a violation of any Lending Sublimit
or Borrowing Base Sublimit.  Notwithstanding the foregoing, following an Event
of Default pledged Cash Equivalents which are the subject of reverse repurchase
obligations can be released in connection with the terms of the applicable
reverse repurchase agreement, and Pledged Items can be released in connection
with the sale of such Pledged Items pursuant to an





                                      -71-
<PAGE>   78

Approved Investor Commitment existing at the time of occurrence of the Event of
Default if, in either case, the proceeds of such sale are deposited into the
Settlement Account.


         4.9     Settlement Account.

                 There has been established with the Agent, for the benefit of
the Secured Parties, a "cash collateral" account of the Company #19-19210
("Settlement Account") into which shall be deposited all cash proceeds from the
sale of any Pledged Item and any payments made by a Servicing Purchaser in
connection with Pledged Servicing Sale Receivables.  Only the Agent shall have
access to the Settlement Account.  Prior to the occurrence of a Default, to the
extent that, as determined by the Agent, the amounts in the Settlement Account
are not needed to keep the Borrowing Base equal to or greater than the Credit
Requirement, the Company may request that the Agent release funds from the
Settlement Account, which funds shall be applied by the Agent as directed by
the Company.  Upon the occurrence of an Event of Default (and during the
continuance thereof) all amounts then on deposit in the Settlement Account, and
any deposits made in the Settlement Account during the continuance of such
Event of Default, shall be withdrawn by the Agent from the Settlement Account
and shall be applied to the Credit Indebtedness in accordance with the
provisions of Paragraph 18 of the Security Agreement and Section 10.4 of this
Agreement.


         4.10    Termination.

                 If all Commitments shall have expired or been terminated
pursuant to the express terms hereof and no Credit Indebtedness shall be
outstanding, the Agent shall promptly deliver or cause to be delivered all cash
in the Settlement Account and all other Collateral to the Company.  The receipt
by the Company of any cash in the Settlement Account and of all Pledged Items
returned or delivered to the Company pursuant to any provision of this
Agreement shall be a complete and full acquittance for the Pledged Items so
delivered, and the Agent, Collateral Agent and the Lenders shall thereafter be
discharged from any liability or responsibility therefor.


         4.11    Abatement of Security Interest.





                                      -72-
<PAGE>   79

                 (a)  Positive Security Event.  If a Positive Security Event
occurs prior to the Termination Date and no Event of Default has occurred and
is continuing, the security interest created under the Security Agreement and
this Agreement in the Collateral shall be abated at the request of the Company
and shall not be effective so long as no Event of Default exists and each of
the following conditions exist:  (i) the Company shall have and maintain a
ratio of (1) Funded Debt less Subordinated Debt to (2) Adjusted Consolidated
Tangible Net Worth plus Subordinated Debt, calculated monthly on a three-month
rolling average basis, of not more than the applicable Unsecured Leverage
Ratio; (ii) the total Debt of the Company, excluding Subordinated Debt, shall
not exceed the Debt Threshold; and (iii) neither the Company nor either
Borrowing Subsidiary shall have, or permit to occur, any Lien upon their assets
other than as permitted under Section 8.11 (other than Section 8.11(o)).  The
conditions under clauses (i) - (iii) of the preceding sentence are referred to
herein collectively as the "Positive Security Conditions".  The Collateral
Agent shall, at the request of the Company and after the Agent has confirmed to
the Collateral Agent that a Positive Security Event has occurred and all
Positive Security Conditions are satisfied, execute and deliver such UCC-3
financing statements as may be required to evidence the abatement of any
security interest that shall previously have been perfected by means of the
filing of financing statements.  As a condition to such abatement, the Company
and each Borrowing Subsidiary shall execute such UCC-1 financing statements and
other documentation as the Collateral Agent may request to permit the security
interest in the Collateral to be reinstated and perfected by the Collateral
Agent without further action by the Company or any Borrowing Subsidiary if a
Negative Security Event should occur thereafter.  Although the Company and
Borrowing Subsidiaries shall continue to deliver Mortgage Loan files and other
information and documents to the Collateral Agent (in a custodial capacity) as
set forth in the Security Agreement even while the security interest is abated,
so long as the security interest is abated the Company shall perform all of the
obligations of the Collateral Agent as set forth in the Security Agreement with
respect to determining the Borrowing Base.  If any of the Positive Security
Conditions shall cease to exist at any time after a Positive Security Event,
such occurrence shall constitute a Negative Security Event.





                                      -73-
<PAGE>   80

                 (b)  Negative Security Event.  If, following a Positive
Security Event, a Negative Security Event occurs, the Facility shall again be
secured in accordance with the terms herein unless and until the Required
Lenders agree to the contrary.  If the Facility again becomes secured pursuant
to the preceding sentence, the Company (with respect to Collateral owned by the
Company) and each Borrowing Subsidiary (with respect to Collateral owned by
such Borrowing Subsidiary) shall be deemed to have automatically (i) re-pledged
and re-granted to the Collateral Agent for the benefit of the Secured Parties a
first priority security interest in the Collateral to secure payment of the
Secured Debt, (ii) consented to the Collateral Agent's filing of the UCC-1
financing statements and dating and otherwise completing, filing and/or
recording, if necessary, any other documentation previously provided by the
Company or such Borrowing Subsidiary pursuant to the provisions of Section
4.11(a) above, and (iii) reaffirmed its appointment of the Collateral Agent to
act as its bailee pursuant to the provisions of Section 9-305 of the Uniform
Commercial Code of any applicable state, and the Collateral Agent (upon receipt
of notice from the Credit Agent that a Negative Security Event has occurred)
shall be deemed to have been informed of and accepted such appointment.
Notwithstanding the foregoing, the Company may, in accordance with the terms of
the succeeding sentence, request that the Required Lenders consent to the
Facility again becoming unsecured despite the occurrence of a Negative Security
Event.  If the Company so desires that the Facility again become unsecured
following a Negative Security Event (even though no Positive Security Event has
occurred since the occurrence of the Negative Security Event), it shall notify
each Lender in writing of such desire within thirty days after the occurrence
of the Negative Security Event (which notice shall identify the facts giving
rise to the Negative Security Event), and the Facility shall again become
unsecured (A) if and only if the Required Lenders so consent within thirty days
after such notification from the Company (a "Negative Event Waiver") and (B)
only so long as no further Negative Security Event (i.e. no Negative Security
Event other than the event referred to in the Company's notice) has occurred
and is continuing.  If the Company's long term unsecured debt ratings decline
further below "A-" as rated by S&P or "A3" as rated by Moody's, or if any other
Negative Security Event occurs after the Company has obtained a Negative Event
Waiver, the Facility shall again become secured in accordance with this Section
unless the Company obtains another Negative Event Waiver





                                      -74-
<PAGE>   81

in accordance with the terms of the preceding sentence.  Finally, if a Positive
Security Event occurs subsequent to the occurrence of a Negative Security
Event, the Facility shall become unsecured at the request of the Company,
subject to and in accordance with the terms and conditions set forth in Section
4.11(a) above.

                 (c)  Lending Restrictions.  If and during such time as the
Credit Indebtedness hereunder may be unsecured in accordance with Section
4.11(a), all Advances requested by the Company or any Borrowing Subsidiary
shall continue to meet the Lending Sublimits and shall be subject to the
conditions precedent set forth in Article V (other than conditions precedent
requiring the Collateral Agent to have a perfected security interest in the
Collateral).


         4.12    Transition from Existing Facility.

                 The Pledge Date and all other relevant delivery dates and time
periods with respect to the determination of Eligible Collateral shall be
calculated to include any delivery dates or holding periods prior to the date
hereof during which Collateral was being held by the Collateral Agent (or was
the subject of an AP Notice), had been delivered to an Approved Investor or had
been redelivered to the Company under the Existing Facility.

         Agreement, the Security Agreement and the Notes and otherwise act on
         behalf of the Company or any Borrowing Subsidiary hereunder or under

         Agreement, and the Lenders under the Existing Facility who are not
         Lenders under this Agreement as to the repayment or conversion of
         loans outstanding to the Company under the Existing Facility, the
         treatment of any interest and fees accrued thereon, and the

         5.3     All Advances.

the representations and warranties of the Company and the Borrowing
Subsidiaries set forth in Articles IV and VI shall be true and correct in all

                 The Company and each of its Affiliates are in compliance with

Agreement, the Security Agreement and the Notes.


         6.5     Valid and Binding Obligations.

                 This Agreement, the Security Agreement and the Notes
constitute legal, valid and binding obligations of the Company and each
Borrowing Subsidiary enforceable against the Company and each Borrowing
Subsidiary in accordance with their respective terms, subject to bankruptcy and
similar laws and other general restrictions on creditor's rights and equitable

         6.6     Financial Statements.

                 (a)      The balance sheet of the Company and its Subsidiaries

         report) and the related statements of income and changes in financial
         position for the fiscal year then ended, copies of which have been
         heretofore furnished to each of the Lenders, fairly present, in
         conformity with GAAP, the financial condition of the Company and its
         Subsidiaries as of such date and the results of the operations and
         changes in financial position of the Company and its Subsidiaries for
         such fiscal year.

                 (b)      The quarterly financial statements of the Company and

                 (c)      Since the date of the December 31, 1996 statements

their respective properties before any court, arbitrator or governmental
department, commission, board, bureau, agency or instrumentality, domestic or
foreign (including, without limitation, the SEC or any regulatory commission of
any jurisdiction), which, if determined adversely to the Company or any
Affiliate, as the case may be, would be reasonably likely to, singly or in the

respective properties or operations, of the Company and its Affiliates or the
transactions contemplated by this Agreement, the Security Agreement and the
Notes.

         6.11    Investment Company.

                 Neither the Company nor any Borrowing Subsidiary is an

with the Lenders that, so long as this Agreement shall remain in effect and so
long as any amounts are outstanding under the Notes or this Agreement, unless

         each of its Subsidiaries to pay all debts and perform all obligations,
         promptly and in accordance with the terms





                                      -82-

         Mortgages to comply with the provisions of such Pledged Mortgages with
         respect to the payment of real estate taxes and insurance premiums in

to, singly or in the aggregate, materially adversely affect its business or
credit, unless the same shall be contested by the Company, a Borrowing
Subsidiary or such other Subsidiary, as the case may be, in good faith and by
appropriate proceedings and such contest shall operate to stay the material
adverse effect of any such non-compliance.

to time, on reasonable prior notice furnish to the Agent, any requesting Lender
or any agents or representatives thereof, or permit such agents or

                                  ARTICLE VIII
                               NEGATIVE COVENANTS

                 The Company covenants and agrees (and each Borrowing
Subsidiary covenants and agrees with respect to Sections 8.1, 8.2, 8.3, 8.4,
8.6, 8.7, 8.8, 8.11, 8.13, 8.14, 8.15, 8.17 and 8.18) with the Lenders that so
long as this Agreement shall remain in effect or any amounts are outstanding
under the Notes or this Agreement, unless the Required Lenders (or all Lenders,
if expressly required) shall otherwise consent in writing, the Company (or the
Borrowing Subsidiaries where applicable) (on a consolidated basis with its
Subsidiaries) shall not, directly or indirectly:


         8.1     Use of Proceeds.

                 Use the amounts obtained under this Agreement for any purposes
other than (i) the purposes described in the recitals hereto, (ii) the funding
or purchasing of Mortgage Loans, (iii) the payment of principal, interest,
fees, expenses and other obligations described in or contemplated by this
Agreement, (iv) payment of Debt of the Company existing on the date hereof, and
(v) such other purposes permitted under this Agreement.  Neither the Company
nor any Borrowing Subsidiary is engaged, nor will they engage, principally or
materially in the business of extending credit for the purpose of "purchasing"
or "carrying" any "margin stock" (within the meanings of each of the quoted
terms under Regulation U).  If requested by a Lender, the Company and each
Borrowing Subsidiary shall each furnish to the Agent for the benefit of the
Lenders a statement in conformity with the requirements of Federal Reserve Form
U-1 referred to in Regulation U.  No part of the proceeds of any Loan will be
used for any purpose which violates, or which would be inconsistent with, the
provisions of the Regulations of the Board of Governors of the Federal Reserve
System as now and from time to time hereafter in effect.


         8.2     Compliance with Security Agreement.

                 Enter into any collateral custodial agreement similar to the
Security Agreement for Mortgage Loans not included in Collateral with any
entity other than the Collateral Agent or fail to duly perform any of its
obligations under the Security Agreement; provided, however, that this Section
shall not prohibit the Company or any Borrowing Subsidiary from entering into
other custodial agreements relating to the possession of





                                      -92-
<PAGE>   99

Mortgage Loans not included in Collateral so long as such agreements are not
made for the purpose of or in connection with the granting of a security
interest in such Mortgage Loans.  Security interests in Mortgage Loans given
for confirmatory purposes in connection with the sale of such Mortgage Loans by
the Company or a Borrowing Subsidiary to investors shall not be considered
agreements "made for the purpose of or in connection with the granting of a
security interest in such Mortgage Loans" within the meaning of the preceding
sentence.


         8.3     Mergers; Subsidiaries.

                 Merge or consolidate with any Person, or sell or otherwise
dispose of (whether in one transaction or in a series of transactions) the
shares of any of its Subsidiaries to any Person, provided that the Company may,
after prior written notice to the Agent and Lenders, (i) undertake such a
merger or consolidation so long as the Company shall be the surviving or
resulting company and (ii) take such action with respect to any Subsidiary
which is not a material part of the Company's overall business operations.


         8.4     Sales.

                 Sell, assign, lease or otherwise dispose of (collectively,
"Transfer"), whether in one transaction or a series of transactions, all or
substantially all of its assets (whether now owned or hereafter acquired) to
any Person, or allow any Subsidiary to Transfer substantially all of its assets
to any Person (other than another Subsidiary or a Parent), provided that the
Company may after prior written notice to the Agent and Lenders allow such
action with respect to any Subsidiary which is not a material part of the
Company's overall business operations.  Transfers described in this Section 8.4
and the mergers, consolidations and dispositions described in Section 8.3
(whether or not permitted by the provisions of such Sections) are referred to
herein as "Fundamental Changes."


         8.5     Debt.  Allow the total Debt (excluding Subordinated Debt) of
the Company and its Subsidiaries (on a consolidated basis) to exceed the sum of
the following (the "Debt Threshold"):

                 (a)      one hundred percent (100%) of the value of the
         Company's cash and "short-term investments";

                 (b)      ninety-eight percent (98%) of the value of the
         Company's "mortgage loans receivable";

                 (c)      ninety percent (90%) of the value of the Company's
         "pool loan purchases" and "mortgage claims receivable", to the extent
         such assets represent VA Mortgage Loans and FHA Mortgage Loans
         repurchased by the Company from GNMA Security





                                      -93-

         Company on account of such Mortgage Loans which is guaranteed by VA or
         insured by FHA, provided however, the Required Lenders can elect upon
         90 days prior notice to the Company not to include such interest
         amount in the calculation of this component of the Debt Threshold;

                 (d)      seventy-five percent (75%) of the amount of Servicing
         Sale Receivables which would qualify as Eligible Pledged Servicing
         Sale Receivables if such Servicing Sale Receivables were pledged as
         Collateral;

                 (e)      seventy-five percent (75%) of "loans held for
         investment";

                 (f)      sixty percent (60%) of the amount of the Company's
         servicing rights as determined in accordance with GAAP on a monthly
         basis (or more frequently if requested by the Agent);

                 (g)      fifty percent of the value of Approved Equity
         Securities, as shown on the most recent quarterly financial statements
         (or as reported on a more frequent basis if required by Agent)
         provided that the maximum amount that can be included in this
         component of the Debt Threshold shall be $100,000,000, as such amount
         may be reduced in accordance with Section 8.16; and

                 (h)      fifty percent (50%) of the amount of Servicing Sale
         Receivables which would not qualify as Eligible Servicing Sale
         Receivables net of any contingent expense holdback relating to such
         Servicing Sale Receivables recorded as a liability under GAAP.

Terms set forth in quotes in this Section shall have the meanings given such
terms in the Company's consolidated financial statements.


         8.6     Ratably Secured Debt.  Incur any Debt which may be entitled to
a security interest in any of the Collateral which would be equal or superior
to the security interest of Collateral Agent as agent for the Secured Parties.


         8.7     Guarantees.

                 Create, incur, assume or suffer to exist any Guarantee of the
Company or a Borrowing Subsidiary except Guarantees in an aggregate combined
amount for the Company and the Borrowing Subsidiaries not to exceed $25,000,000
at any one time outstanding.

         construction or otherwise) by the Company or its Subsidiaries, each of
         which Liens either (A) existed on such property before the time of its
         acquisition and was not created in anticipation thereof at the request
         or direction of the Company, or (B) was created solely for the purpose
         of securing Debt representing, or incurred to finance, refinance or
         refund, the cost (including the cost of construction) of the
         respective property; provided, that no such Lien shall extend to or

         respective property so acquired and improvements thereon;

                 (j)      Liens incidental to the conduct of the Company's or a

         Borrowing Subsidiary's mortgage-related businesses which do not secure
         Debt and do not, in the aggregate, materially detract from the value
         of its properties in the aggregate or materially impair the use
         thereof in the ordinary course of the Company's or such Borrowing
         Subsidiary's business;

         were not created in anticipation thereof, (ii) any such Lien is not
         spread to cover any property or assets of such corporation after the
         time such corporation becomes a Subsidiary (other than any such
         spreading resulting from "after-acquired property" clauses in
         existence on the date such corporation became a Subsidiary) and (iii)
         the amount of Debt secured thereby is not increased;

                 (l)      any extension, renewal or replacement (or successive

         principal amount of Debt so secured immediately prior to the time of
         such extension, renewal or replacement, and that such extension,
         renewal, or replacement Lien shall be limited to all or a part of the
         property which secured the Lien so extended, renewed or replaced (plus
         improvements on such property);

                 (m)      Liens (not otherwise permitted hereunder) which
         secure obligations not exceeding (as to the Company and all
         Subsidiaries) $15,000,000 in an aggregate principal amount at any one
         time outstanding;

                 (n)      Liens (not otherwise permitted hereunder) which
         secure obligations (as to the Company and all Subsidiaries) (1)

         Company in the ordinary course of its mortgage banking business in
         connection with puts, calls, swaps and other interest rate hedging
         products, options and futures contracts to provide protection from
         interest rate fluctuation; and

                 (o)      the Liens arising under the Security Agreement or any
         other Credit Document;

provided, however, that so long as no Event of Default has occurred and is
continuing and the security interest in favor of the Collateral Agent is in
effect and is not abated pursuant to Section 4.11(a), the Company may also
permit Liens on Securities and Mortgage Loans owned by the Company (other than
Securities or

other than the Secured Parties for the purpose of originating or purchasing
such Securities or Mortgage Loans.


         8.12    Credit Requirement.

                 Permit the Borrowing Base to be less than the Credit

         8.13    Affiliate Transactions.

                 Enter, or permit any Subsidiary to enter, into any
transactions with the Company's Parent or Affiliates that is not an
arm's-length transaction or that in any material respect is less advantageous
to the Company or such Subsidiary than a similar typical transaction with an
unrelated third-party; make any loans or advances to the Parent or any
Affiliates with financial terms more advantageous to the Parent or Affiliate
than the terms of loans and advances made to the Company from any such Parent
or Affiliate; or make any net loans or advances to the Parent or any Affiliates
which would cause any violation of Sections 7.9 or 8.9.


         8.14    Conduct of Business.

                 Except as permitted under Section 8.8:

         than businesses related to its current businesses, materially change

                 (b)      fail to maintain its corporate existence, licenses,
         franchises and privileges.


         8.15    FHA and other Approvals.

to withdraw its approval of the Company or any Borrowing Subsidiary, or become
ineligible or allow any Borrowing Subsidiary to become ineligible as a lender
under the VA loan guaranty program.


         8.16    Restricted Payments.

                 Make any Restricted Payments; provided, however, so long as no
Default arising from the Company's failure to comply with Section 7.9 has
occurred and is continuing (or would result from any such payment) and no Event
of Default has occurred and is continuing (or would result from any such
payment), the Company





                                     -100-
<PAGE>   107

may make Restricted Payments as expressly permitted by subparagraphs (a) and
(b) below:

                 (a)      The Company may make Restricted Payments in an amount
         which, when added to all other Restricted Payments (including
         Restricted Payments made pursuant to Section 8.16(b)(i)) made
         subsequent to June 30, 1997, does not exceed fifty percent (50%) of
         the increase, if any, in Adjusted Consolidated Tangible Net Worth from
         June 30, 1997 through the completed calendar quarter preceding any
         such Restricted Payment.

                 The increase in Adjusted Consolidated Tangible Net Worth
         referenced in this Subsection (a) shall be computed without regard to
         any increase or decrease resulting from the following activities: (1)
         the contribution or distribution of Capital Securities, (2) cash
         equity contributions to the Company, (3) the receipt of proceeds of
         issuances of stock of the Company, (4) increases or decreases in the
         amount of Subordinated Debt, or (5) the payment of permitted
         Restricted Payments.

                 (b)      The Company may, without regard to the maximum limit
         on Restricted Payments established by Subsection (a) above:

                 (i) pay dividends required to be paid on its Series A
                 Preferred Stock and pay interest that is due and payable on
                 the Subordinated Debt, provided that all payments made
                 pursuant to this clause (i) shall still be included for
                 purposes of determining the maximum amount of dividends and
                 distributions payable under Subsection (a);

                 (ii) make additional Restricted Payments not to exceed the
                 Maximum Special Dividend Amount in the aggregate, which
                 additional Restricted Payments made pursuant to this clause
                 (ii) shall not be included in determining the maximum amount
                 of Restricted Payments made under subsection (a);

                 (iii) distribute Capital Securities; and

                 (iv)  distribute the proceeds of issuances of stock to an
                 Affiliate (but not any proceeds received in connection with
                 any public or secondary offering of stock).

         At the time the Company pays or makes any such Restricted Payment, it
shall notify the Agent in writing of the amount of such payment, which notice
shall (1) specify under which subparagraph and clause above the Restricted
Payment is being





                                     -101-
<PAGE>   108

made and (2) contain such information as is necessary to demonstrate that such
dividend is permissible under the applicable subparagraph and clause.

         As used herein, "Maximum Special Dividend Amount" shall mean
$90,900,000 plus (a) the amount of servicing holdback net proceeds collected by
the Company after June 30, 1997, up to a maximum of $29,200,000, plus (b)
one-half of the liquidation proceeds of U.S. West, Inc.  redeemable preferred
stock owned by the Company, up to a maximum of $25,000,000, provided that such
liquidation proceeds shall be included in the Maximum Special Dividend Amount
only if the other half of such liquidation proceeds is used to repay Credit
Indebtedness and the maximum amount that can be included in the component of
the Debt Threshold set forth in Section 8.5(g) relating to Approved Equity
Securities is permanently reduced by the amount of any Special Dividend
attributable to such liquidation proceeds.


         8.17    Borrowing Subsidiary Liabilities and Secured Debt.  Allow (i)
TMA's total liabilities (as defined by GAAP), other than liabilities to the
Company or its Affiliates, to exceed at any time $5,000,000, (ii) CPM's total
liabilities for borrowed money other than money borrowed by CPM under this
Agreement or borrowed from the Company or its Affiliates to exceed at any time
$15,000,000, or (iii) any Borrowing Subsidiary to create or suffer any Liens on
any of its assets to secure the repayment of borrowed money.


         8.18    Funding of Borrowing Subsidiary Mortgage Loans.  Discontinue
the method by which the Company directly funds Mortgage Loans pledged by the
Borrowing Subsidiaries as Collateral or amend or terminate any Funding
Agreement without the prior written consent of the Required Lenders, which
consent shall not be unreasonably withheld.


         8.19    Subordinated Debt Indenture.

                          (a) Enter into, without the prior written consent of
         the Required Lenders, any amendment or modification of the
         Subordinated Debt Indenture or other documents evidencing or governing
         the terms of the Subordinated Debt if such amendment or modification
         would change (i) the principal amount of or rate of interest on the
         Subordinated Debt, (ii) the terms of repayment of the Subordinated
         Debt, (iii) the provisions relating to the deferral of interest on the
         Subordinated Debt, (iv) any terms or provisions of Article 12
         (Subordination) of the Subordinated Debt Indenture, (v) the definition
         of "Event of Default" in the Subordinated Debt Indenture, or (vi) the
         provision of the Subordinated Debt Indenture which requires the
         trustee to give certain holders of senior indebtedness notices of
         defaults, accelerations and certain other events; provided, however,
         that the Lenders





                                     -102-
<PAGE>   109

         hereby consent to that certain First Supplemental Indenture dated
         December 1, 1995; or

                          (b) Enter into, without the prior written consent of
         the Agent, any material amendment or modification of the Subordinated
         Debt Indenture or other documents evidencing or governing the terms of
         the Subordinated Debt other than the amendments or modifications
         requiring the consent of the Required Lenders pursuant to clause (a)
         above; or

                          (c) Consent, without prior written notice to the
         Agent, to any change in the trustee under the Subordinated Debt
         Indenture.


                                   ARTICLE IX
                                   THE AGENT


         9.1  Appointment and Authorization.

                 (a)      Each Lender irrevocably appoints and authorizes the
         Agent to take such action as agent on its behalf and to exercise such
         powers under this Agreement as are delegated to the Agent by the terms
         hereof together with all such powers as are reasonably incidental
         thereto.

                 (b)      The Agent is hereby authorized to enter into the
         Security Agreement on behalf of the Lenders and all obligations of the
         Lenders thereunder shall be binding upon each Lender as if such Lender
         had executed the Security Agreement.  Each Lender hereby appoints and
         authorizes the Collateral Agent to act on its behalf in the capacity
         described in the Security Agreement and authorizes the Collateral
         Agent to act on such Lender's behalf in all respects with regard to
         performance under the Security Agreement.

                 (c)      Unless and until the Agent shall have received the
         directions of the Required Lenders as provided in Section 10.2(1) or
         (2) or of all Lenders, if expressly required hereunder, the Agent may
         (but shall not be obligated to) take or refrain from taking such
         action, or direct the Collateral Agent to take or refrain from taking
         such action with respect to an Event of Default as it shall deem
         advisable in the best interests of the Lenders.

                 (d)      The Agent shall not be required to take any action
         hereunder if it shall reasonably determine that by so doing it may
         incur criminal or civil liability.





                                     -103-
<PAGE>   110


         9.2     Agent and Affiliates.

                 The Agent shall have the same rights and powers under this
Agreement as any other Lender and may exercise or refrain from exercising the
same as though it were not the Agent, and the Agent and its Affiliates may
accept deposits from, lend money to, and generally engage in any kind of
business with, the Company, any Subsidiary or Affiliate of the Company as if it
were not the Agent hereunder.


         9.3     Action by Agent.

                 The obligations of the Agent hereunder are only those
expressly set forth herein.  Without limiting the generality of the foregoing,
the Agent shall not be required to take any action with respect to any Default,
except as expressly provided in this Article IX or in Article X.


         9.4     Consultation with Experts.

                 The Agent may consult with legal counsel (who may be counsel
for the Company), independent public accountants and other experts selected by
it and shall not be liable for any action taken or omitted to be taken by it in
good faith in accordance with the advice of such counsel, accountants or
experts.


         9.5     Liability of Agent.

                 (a)      Neither the Agent nor any of its directors, officers,
         agents, or employees shall be liable for any action taken or not taken
         by it in connection herewith (i) with the consent or at the request of
         the Required Lenders or of all Lenders, if required or (ii) in the
         absence of its own gross negligence or willful misconduct.

                 (b)      Neither the Agent (except as otherwise provided in
         this Agreement) nor any of its directors, officers, agents or
         employees shall be responsible for or have any duty to ascertain,
         inquire into or verify

                               (i)  any statement, warranty or representation
                  made in connection with this Agreement or any Advance 
                  hereunder;

                              (ii)  the performance or observance of any of the
                 covenants or agreements of the Company or any Borrowing
                 Subsidiary;

                             (iii)  the satisfaction of any condition specified
                  in Article V, except receipt of items required to be





                                     -104-
<PAGE>   111

                 delivered to the Agent and the determination of the amount of
                 the Credit Requirement; or

                              (iv)  the validity, effectiveness or genuineness
                 of this Agreement, the Notes or any other instrument or
                 writing furnished in connection herewith.

                 (c)      The Agent shall not incur any liability by acting in
         reliance upon any notice, consent, certificate, statement, or other
         writing (which may be a bank wire, telex or similar writing) or
         telephone communication believed by it to be genuine or, in the case
         of a writing, to be signed by the proper party or parties.


         9.6     Indemnification.

                 (a)      Each Lender shall, ratably in accordance with its
         share of the Aggregate Commitment (or, if the Commitments have been
         terminated, then in accordance with its share of aggregate Loans then
         outstanding) at the time the Agent or the Collateral Agent incurred
         such liability, indemnify the Agent and the Collateral Agent (to the
         extent not reimbursed by the Company or a Borrowing Subsidiary)
         against any cost, expense (including reasonable counsel fees and
         disbursements), claim, demand, action, loss or liability (except such
         as result from the indemnified party's gross negligence or willful
         misconduct) that the Agent or the Collateral Agent may suffer or incur
         in connection with this Agreement or the Security Agreement or any
         action taken or omitted by the Agent or the Collateral Agent hereunder
         or thereunder.

                 (b)      For the purposes of this Section, the amount of any
         Commitment of any Lender shall be the highest amount of such
         Commitment of such Lender during the course of any event for which
         indemnity is sought.

                 (c)      The provisions of this Section shall survive the
         termination of this Agreement.


         9.7     Credit Decision.

                 Each Lender acknowledges that it has itself been and will
continue to be, independently and without reliance upon the Agent or any other
Lender, solely responsible for making its own independent appraisal of and
investigations into the financial condition, creditworthiness, condition,
affairs, status and nature of the Company and the Borrowing Subsidiaries.
Accordingly, each Lender confirms to the Agent that it has not relied, and will
not hereafter rely, on the Agent or any other Lender (i) except as otherwise
provided in this Agreement, to check or inquire on such Lender's behalf into
the adequacy,





                                     -105-
<PAGE>   112

accuracy or completeness of any information provided by the Company or any
Borrowing Subsidiary under or in connection with this Agreement or the
transactions herein contemplated (whether or not such information has been or
is hereafter distributed to such Lender by the Agent) or (ii) to assess or keep
under review on such Lender's behalf the financial condition, creditworthiness,
condition, affairs, status or nature of the Company, any Borrowing Subsidiary
or any Approved Investor.


         9.8     Resignation or Removal and Appointment of Successor Agent.

                 The Agent may resign at any time by giving 90 days prior
written notice thereof to the Lenders and the Company.  The Agent may be
removed at any time upon ninety (90) days prior written notice from the
Required Lenders.  Upon any such resignation or removal notice the Required
Lenders shall have the right to appoint a successor Agent; provided that such
appointment, unless made after the occurrence of a Default and during the
continuance thereof, shall be subject to the consent of the Company, which
consent shall not be unreasonably withheld.  If the Company and/or Required
Lenders, as applicable, are unable to agree on the appointment of a successor
agent within such 90 day period, the retiring agent shall appoint one of the
Lenders as a successor agent for the Lenders.  Upon the appointment of a
successor Agent, that successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring
Agent, and the retiring Agent shall be discharged from its duties and
obligations under this Agreement; provided, however, that the resigning Agent
shall not be discharged from any liability as a result of its or its
directors', officers', agents' or employees' gross negligence or willful
misconduct in connection with the performance of its duties and obligations
under this Agreement prior to the effective date of its resignation.  After any
retiring Agent's resignation hereunder as Agent, the provisions of this Article
IX shall inure to its benefit as to any actions taken or omitted to be taken by
it while it was Agent under this Agreement.


         9.9     Compensation.

                 Compensation of the Agent for its services hereunder and
reimbursement for any expenses incurred by it in the performance of its duties
hereunder shall be paid by the Company pursuant to a separate written agreement
between the Agent and the Company.


         9.10    Release of Collateral Documents.

                 The Collateral Agent shall not release any Pledged Items
except as provided herein or in connection with the enforcement of any remedies
hereunder.





                                     -106-
<PAGE>   113


         9.11    Knowledge of Defaults.

                 The Agent shall not be deemed to have knowledge or notice of
the occurrence of any Event of Default unless the Agent has received notice
from a Lender or the Company referring to this Agreement, describing such Event
of Default and stating that such notice is a "Notice of Default."  The Agent
shall notify the Lenders within a reasonable time after the Agent has notice of
the occurrence of an Event of Default, which notice shall describe the Event of
Default.

         9.12    Reports.

                 The Agent may, at its option with the approval of the Company,

         herein (other than the representations and warranties contained in

         when made or deemed made in any material respect; provided however
         that if the facts resulting in the breach of any such representation
         or warranty are susceptible of correction, such breach shall not

                 (f)      The Company or any Borrowing Subsidiary, as
         applicable, shall fail to perform or observe any term, covenant or
         agreement contained in Sections 7.10, 8.1, 8.3, 8.4, 8.6, 8.7, 8.9,

         covenant contained in Section 8.12 and such failure remains unremedied
         for one Business Day, or (ii) fail to perform any term, covenant or
         agreement contained in Sections 7.7(a), 7.9, 8.5, 8.8 or 8.16, and

         the Collateral Agent is not abated) or in the Security Agreement on
         its part to be performed or observed and any such failure remains
         unremedied for thirty (30) days after written notice thereof shall
         have been given to the Company or such Borrowing Subsidiary (as
         applicable) by the Agent or the Collateral Agent; or

                 (i)      An Event of Default shall exist under any other
         Credit Document; or

                 (j)      Either this Agreement, the Notes or the Security
         Agreement shall, at any time after its execution and delivery, for any
         reason cease to be in full force and effect (unless such occurrence is
         in accordance with its terms or after payment thereof) or shall be

         Collateral Agent shall deny that it has any further liability or
         obligation thereunder; or

         without the application or consent of the Company or of such
         Subsidiary, as the case may be, and such appointment shall continue
         undischarged for a period of 60 days, (vi) institute (by petition,
         application, answer, consent or otherwise) any bankruptcy, insolvency,
         reorganization, arrangement, readjustment of debt, dissolution,

         judgment, writ, warrant of attachment or execution or similar process
         issued or levied in respect of any of its obligations (alleged or
         otherwise) against any of its property involving any amount in excess
         of $5,000,000 and such judgment, writ or similar process shall not be

         Indebtedness in excess of $25,000,000 in the aggregate or (ii) any
         event specified in any note, agreement, indenture or other document
         evidencing or relating to any such Debt in excess of $25,000,000 shall
         occur if the effect of such event is to cause, or to permit the holder
         or holders of such Debt (or a trustee or agent on behalf of such
         holder or holders) to cause, such Debt to become due, or to be prepaid
         in full, prior to its stated maturity, and in either case any notice
         or cure period has expired and such default has not been waived in
         writing by the holder of such Debt; or

                 (m)      An event or condition occurs or exists with respect
         to any Plan concerning which the Company is under an obligation to
         furnish a report to the Lenders in accordance with Section 7.7(h) and
         as a result of such event or condition, together with all other such
         events or conditions, the Company or any ERISA Affiliate has incurred

         foregoing) which is material in relation to the financial position of

                                     -109-
<PAGE>   116

                 (n)      A Change in Control shall occur with respect to the
         Company; or

                 (o)      Except in connection with a Positive Security Event,
         the lien against the Collateral created under the Security Agreement
         for the benefit of the Secured Parties shall cease to be a perfected,
         first priority security interest; provided, however, that if the
         Secured Parties shall cease to have a perfected, first priority
         interest in a portion of the Collateral, such cessation shall not
         constitute an Event of Default so long as the Collateral in which the
         Secured Parties have a perfected, first priority interest is
         sufficient to cause the Borrowing Base to exceed the Credit
         Requirement;

then, and in every such event and at any time thereafter during the continuance
of such event, the Agent and the Lenders shall have the rights described in the
following Sections of this Article X.


         10.2    Remedies.

                 (1)      Upon the occurrence of any Event of Default the Agent
         may, and at the direction of the Required Lenders shall, at the same
         or different times, take one or more of the following actions:  (i) by
         notice to the Company terminate the Commitments and they shall
         thereupon terminate, (ii) by notice to the Company declare the
         Obligations to be, and the Obligations shall thereupon become,
         immediately due and payable without presentment, demand, protest or
         other notice of any kind, all of which are hereby waived by the
         Company and the Borrowing Subsidiaries, provided that in the case of
         any of the Events of Default specified in subparagraph (k) of Section
         10.1 , without any notice to the Company or any Borrowing Subsidiary
         or any other act by the Agent or the Lenders, the Commitments shall
         thereupon terminate and the Obligations shall become immediately due
         and payable without presentment, demand, protest or other notice of
         any kind, all of which are hereby waived by the Company and the
         Borrowing Subsidiaries.  Following the occurrence and during the
         continuance of a Default, no Lender shall be obligated to fund any
         Loan hereunder.

                 (2)      Following the occurrence and during the continuance
         of an Event of Default, the Company and the Borrowing Subsidiaries
         agree that the Company, the Borrowing Subsidiaries and the Agent
         shall, at the request of the Required Lenders, implement certain
         procedures with respect to the Company's and the Borrowing
         Subsidiaries' funding of AP Mortgages, all at the Company's sole
         expense.  Such procedures may include, but are not limited to:  (i)
         reducing the advance rate against AP Mortgages for purposes of





                                     -110-
<PAGE>   117

         determining the Mortgage Collateral Value component of the Borrowing
         Base, (ii) requiring that if (A) AP Mortgages are funded with wire
         transfers, such wire transfers originate from accounts located at a
         lending office of a Lender, (B) AP Mortgages are funded from accounts
         which are not located at a lending office of a Lender, the financial
         institution which holds such account enter into an agreement with the
         Company or the applicable Borrowing Subsidiary (as applicable) and the
         Agent which shall provide that the Agent shall have exclusive dominion
         and control over the funds in such account, and (iii) requiring the
         Company and the Borrowing Subsidiaries to provide the Agent and the
         Lenders with such information regarding the funding of such AP
         Mortgages as the Required Lenders may reasonably request.  The Company
         and the Borrowing Subsidiaries, at their expense, shall from time to
         time execute and deliver to the Agent or the Collateral Agent all such
         assignments, certificates, supplemental documents, and financing
         statements, and shall do all other acts or things, as the Agent may
         reasonably request in order to more fully implement such procedures.

                 (3)      Upon the occurrence of any Event of Default, the
         Agent and the Collateral Agent, on behalf of the Secured Parties,
         shall be entitled to all rights and remedies hereunder and under the
         Security Agreement and all other rights and remedies at law or in
         equity existing in or conferred upon the Secured Parties by other
         jurisdictions or other applicable law.

                 (4)      The Company and the Borrowing Subsidiaries waive any
         right to require the Agent, the Collateral Agent or any Lender to (i)
         proceed against or exhaust any of its remedies against the Company,
         any Borrowing Subsidiary or any other Person in any particular order,
         (ii) proceed against or exhaust any of the Collateral or pursue its
         rights and remedies as against the Collateral in any particular order
         or (iii) pursue any other remedy in its power.

                 (5)      The Agent on behalf of the Lenders may, but shall not
         be obligated to, advance any sums or do any act or thing necessary to
         uphold and enforce the lien and priority of, or the security intended
         to be afforded by, any Pledged Mortgage, including, without
         limitation, payment of delinquent taxes or assessments and insurance
         premiums.  The Company and the Borrowing Subsidiaries shall provide
         any and all information required by the Agent or the Collateral Agent
         to administer this Agreement or collect on the Collateral.  All
         advances, charges, costs and expenses, including reasonable attorneys
         fees, incurred or paid by the Agent in exercising any right, power or
         remedy conferred by this Agreement, or in the enforcement hereof (or
         by any Lender acting on instruction of the Required Lenders in the





                                     -111-
<PAGE>   118

         enforcement hereof), together with interest thereon at the rate per
         annum of two percent (2%) plus the Alternate Base Rate from the time
         of payment until repaid, shall become a part of the Credit
         Indebtedness.

                 (6)      No failure on the part of the Agent or any Lender to
         exercise, and no delay in exercising, any right, power or remedy
         hereunder shall operate as a waiver thereof; nor shall any single or
         partial exercise by the Agent or any Lender of any right, power or
         remedy hereunder preclude any other or further exercise thereof or the
         exercise of any other right, power or remedy.  The remedies herein
         provided are cumulative and are not exclusive of any remedies provided
         by law.


         10.3    Notice of Default.

                 The Agent may, and at the direction of the Required Lenders
shall, give notice to the Company under Section 10.1(d), 10.1(h) or 10.2 and
shall thereupon notify all Lenders thereof.


         10.4    Application of Proceeds.

                 (a)      After the occurrence of an Event of Default, the
portion of the proceeds of any sale or enforcement of all or any part of the
Collateral which is delivered to the Agent by the Collateral Agent pursuant to
the provisions of the Security Agreement shall be applied by the Agent, after
taking into account any adjustments made pursuant to Section 2.3(e):

                 First, to the extent not already paid from the Collateral
         proceeds by the Collateral Agent, to payment of all costs and expenses
         of such sale or enforcement, including reasonable compensation to the
         Agent's agents and counsel, and all expenses, liabilities and advances
         made or incurred by the Agent or any Lender acting on instructions of
         the Required Lenders in connection therewith;

                 Second, to the extent not already paid from the Collateral
         proceeds by the Collateral Agent, to the payment of all costs and
         expenses incurred by the Collateral Agent under the Security
         Agreement;

                 Third, to the payment of accrued and unpaid interest on the
         Credit Indebtedness (including the accrued and unpaid interest
         portion, if any, of the Approved GNMA Letter of Credit Obligations),
         fees due hereunder and all other unpaid Credit Indebtedness other than
         the principal amount of Loans, the face amount (whether drawn or
         undrawn) of Approved GNMA Letters of Credit, and the Approved Secured
         Rate Hedging Obligations, ratably according to the respective amounts
         owing or due each Lender or Non-Lender Balance Bank until such amounts
         are paid in full;





                                     -112-
<PAGE>   119

                 Fourth, to the total unpaid principal amount of all Loans and
         to the unpaid face amount (whether drawn or undrawn) of Approved GNMA
         Letters of Credit, and to all Approved Secured Rate Hedging
         Obligations then due and payable, ratably according to the amount due
         each Lender (provided, however, that proceeds applicable to the
         undrawn face amount of Approved GNMA Letters of Credit shall be
         distributed in accordance with Section 10.5 below) until such amounts
         are paid in full; and

                 Fifth, to the payment to the Company, or to its successors or
         assigns, or as a court of competent jurisdiction may direct, of any
         surplus then remaining from such proceeds.

                 (b)      The Agent shall have absolute discretion as to the
         time of application of any such proceeds, moneys or balances in
         accordance with this Agreement.

                 (c)      If the proceeds of any such sale are insufficient to
         cover the costs and expenses of such sale, as aforesaid, and the
         payment in full of the Credit Indebtedness, the Company and each
         Borrowing Subsidiary shall remain liable for any deficiency.


         10.5    Letter of Credit Cash Collateral Accounts.

                 (a)      Upon the Agent's receipt of any Collateral proceeds
         to be applied to the undrawn face amount of any Approved GNMA Letters
         of Credit pursuant to Section 10.4(a), a separate cash collateral
         account (each a "Letter of Credit Account") shall be established with
         the Agent for each outstanding Approved GNMA Letter of Credit.  Each
         Letter of Credit Account shall be established in the name of the
         Company but shall be under the sole dominion and control of the Agent,
         for the benefit of the Lenders, and the Company shall have no interest
         therein.  All funds deposited into the Letter of Credit Accounts from
         time to time shall be invested by the Agent at its discretion in
         certificates of deposit of First Chicago having a maturity not
         exceeding 30 days, and all amounts earned thereon shall also be held
         in the Letter of Credit Account to be disbursed in accordance with
         Section 10.5(b).  In addition to the foregoing, the Company hereby
         grants to the Agent, for the benefit of the Lenders, a properly
         perfected security interest in and to each Letter of Credit Account
         and any funds that may hereafter be on deposit in such account and the
         proceeds thereof.

                 (b)      Upon the Agent's receipt of any Collateral proceeds
         to be applied to the undrawn face amount of any particular Approved
         GNMA Letter of Credit pursuant to Section 10.4, such proceeds shall be
         deposited by the Agent into the Letter of





                                     -113-
<PAGE>   120

         Credit Account applicable to that particular Approved GNMA Letter of
         Credit.  Such funds shall be promptly disbursed from the applicable
         Letter of Credit Account to reimburse the applicable Issuing Bank for
         drafts drawn from time to time under the applicable Approved GNMA
         Letter of Credit.  If an Approved GNMA Letter of Credit is drawn upon
         and the funds held in the Letter of Credit Account applicable to that
         Approved GNMA Letter of Credit are insufficient to reimburse the
         Issuing Bank in full for all Approved GNMA Letter of Credit
         Obligations applicable thereto, such unreimbursed obligations shall,
         for purposes of Section 10.4, thereafter be considered unpaid Loan
         principal due and owing to the Issuing Lender.  If (i) an Approved
         GNMA Letter of Credit is fully drawn upon and all Approved GNMA Letter
         of Credit Obligations relating thereto are paid in full or (ii) an
         Approved GNMA Letter of Credit expires or is otherwise terminated (and
         thus no further Approved GNMA Letter of Credit Obligations exist with
         respect to such Approved GNMA Letter of Credit), then any funds then
         held in the Letter of Credit Account relating to such Approved GNMA
         Letter of Credit shall be considered Collateral proceeds which shall
         again be distributed to the Agent to be disbursed in accordance with
         Section 10.4.

               BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS


         11.1    Successors and Assigns.

                 The terms and provisions of the Credit Documents shall be
binding upon and inure to the benefit of the Company, the Borrowing
Subsidiaries and the Lenders and their respective successors and assigns,
except that neither the Company nor any Borrowing Subsidiary shall have the
right to assign its rights or obligations under the Credit Documents without
the consent of all the Lenders and any assignment by any Lender must be made in
compliance with Section 11.3.  The Agent may treat the payee of any Note as the
owner thereof for all purposes hereof unless and until such payee complies with
Section 11.3 in the case of an assignment thereof or, in the case of any other
transfer, a written notice of the transfer is filed with the Agent.  Any
assignee or transferee of a Note agrees by acceptance thereof to be bound by
all the terms and provisions of the Credit Documents.  Any request, authority
or consent of any person, who at the time of making such request or giving such
authority or consent is the holder of any Note, shall be conclusive and binding
on any subsequent holder, transferee or assignee of such Note or of any Note or
Notes issued in exchange therefor.

         11.2    Participations.

                 (a)      Permitted Participants; Effect.  Any Lender may, in
         the ordinary course of its business and in accordance with applicable
         law, at any time sell to one or more banks or other entities ("
         Participants") participating interests in any Loan owing to such
         Lender, any Note held by such Lender, any Commitment of such Lender or
         any other interest of such Lender under the Credit Documents.  In the
         event of any such sale by a Lender of participating interests to a
         Participant, such Lender's obligations under the Credit Documents
         shall remain unchanged, such Lender shall remain solely responsible to
         the other parties hereto for the performance of such obligations, such
         Lender shall remain the holder of any such Note for all purposes under
         the Credit Documents, all amounts payable by the Company or any
         Borrowing Subsidiary under this Agreement shall be determined as if
         such Lender had not sold such participating interests, and the
         Company, each Borrowing Subsidiary and the Agent shall continue to
         deal solely and directly with such Lender in connection with such
         Lender's rights and obligations under the Credit Documents.

                 (b)      Voting Rights.  Except as otherwise expressly
         provided in the Credit Documents, each Lender shall retain the sole
         right to approve, without the consent of any Participant, any
         amendment, modification or waiver of any provision of the Credit
         Documents other than any amendment, modification or waiver with
         respect to any Loan or Commitment in which such Participant has an
         interest which (i) forgives principal, interest or Fees or reduces the
         interest rate or Fees payable with respect to any such Loan or
         Commitment, (ii) postpones any date fixed for any regularly-scheduled
         payment of principal of, or interest on, any such Loan or Fees on any
         such Commitment, (iii) releases Collateral beyond the releases
         expressly provided for herein, or (iv) extends the Termination Date.

                 (c)      Benefit of Set-Off.  The Company and the Borrowing
         Subsidiaries agree that each Participant shall be deemed to have the
         right of set-off provided pursuant to Section 12.10(a) in respect of
         its participating interest in amounts owing under the Credit Documents
         to the same extent as if the amount of its participating interest were
         owing directly to it as a Lender under the Credit Documents, provided
         that each Lender shall retain the right of set-off provided in Section
         12.10(a) with respect to the amount of participating interests sold to
         each Participant.  The Lenders agree to share with each Participant,
         and each Participant, by exercising the right of set-off provided in
         Section 12.10(a), agrees to share with each Lender, any amount
         received pursuant to the exercise of its right of set-off, such
         amounts to be shared in accordance with Section 12.10(b) as





                                     -115-
<PAGE>   122
         if each Participant were a Lender.  Neither the Company nor any
         Borrowing Subsidiary is a party to the agreement among the Lenders and
         Participants set forth in the immediately preceding sentence, and such
         sentence may be amended without the consent of either the Company or
         any Borrowing Subsidiary.


         11.3  Assignments.

                 (a)      Permitted Assignments.  Any Lender may, with the
         prior written consent of Agent (which consent shall not be
         unreasonably withheld or delayed), in the ordinary course of its
         business and in accordance with applicable law, at any time assign to
         one or more banks or other entities (" Purchasers") all or any part of
         its rights and obligations under the Credit Documents, provided that,
         unless an Event of Default has occurred and is then continuing, the
         prior written consent of the Company to the identity of any such
         Purchaser shall be required, and the Company agrees that such consent
         shall not be unreasonably withheld or delayed, except that no consent
         of the Agent or the Company shall ever be required for (i) any
         assignment to a Person directly or indirectly controlling, controlled
         by or under direct or indirect common control with the assigning
         Lender or (ii) the pledge or assignment by a Lender of such Lender's
         Note and other rights under the Loan Documents to any Federal Reserve
         Bank in accordance with applicable law.  Notwithstanding the
         foregoing, no assignment of Loans or Commitments which requires the
         consent of the Agent or the Company may be made if the assignment
         would result in either the assigning Lender or the Purchaser (which
         may be an existing Lender) holding a Commitment of less than
         $10,000,000; provided, however, that if (due to reductions in the
         Aggregate Commitment) a Lender's Commitment is less than $10,000,000,
         such Lender may assign all (but not less than all) of its Commitment
         in accordance with the terms of this Section notwithstanding the fact
         that such Commitment is less than $10,000,000.

                 (b)      Effect; Effective Date.  Upon delivery to the Agent
         of a New/Modified Commitment Supplement in the form of Exhibit H
         hereto executed by the assigning Lender and the Purchaser and payment
         to the Agent of an assignment fee of $3,500, such assignment shall
         become effective on the effective date specified in such notice of
         assignment. On and after the effective date of such assignment, such
         Purchaser shall for all purposes be a Lender party to this Agreement
         and any other Credit Document executed by the Lenders and shall have
         all the rights and obligations of a Lender under the Credit Documents,
         to the same extent as if it were an original party hereto, and no
         further consent or action by the Company, the Lenders or the Agent
         shall be required to release the transferor Lender with respect to the
         percentage of the Commitments and Loans assigned to such Purchaser. 
         Upon the consummation of any assignment to a Purchaser pursuant to
         this Section, the transferor Lender, the Agent, the Company and the
         Borrowing Subsidiaries shall make appropriate arrangements so that
         replacement Notes are issued to such transferor Lender and new Notes
         or, as appropriate, replacement Notes, are issued to such Purchaser,
         in each case in principal amounts reflecting their respective  
         Commitments, as adjusted pursuant to such assignment.

      11.4 Dissemination of Information.

        The Company and the Borrowing Subsidiaries authorize each Lender to
disclose to any Participant or any other Person acquiring an interest in the
Credit Documents by operation of law (each a "Transferee") and any prospective
Transferee any and all information in such Lender's possession concerning the
creditworthiness of the Company and its Subsidiaries, provided that the
transferor shall obtain from any such Transferee or prospective Transferee,
prior to disclosing any such information, a confidentiality agreement executed
by the Transferee or prospective Transferee agreeing to be bound by any 
confidentiality requirements with respect to such information which are imposed
upon the Lenders under the terms of the Credit Documents.
        
      11.5  Tax Treatment.
 
        If any interest in any Credit Document is transferred to any Transferee
which is organized under the laws of any jurisdiction other than the United
States or any State thereof, the transferor Lender shall cause such Transferee,
concurrently with the effectiveness of such transfer, to comply with all 
applicable provisions of the Code with respect to withholding and other tax 
matters.

all instructions, notices and other communications to be given to any party

certified mail, postage prepaid, private delivery service or by facsimile, and

the time of day, if applicable) when actually received by the intended party at
its address or facsimile or telephone number as set forth below (or as such

     12.3  Survival and Termination of Agreement.

          All covenants, agreements, representations and warranties made herein
and in the certificates and other documents delivered pursuant hereto shall
survive the funding of the Notes and shall continue in full force and effect to
the Termination Date or so long as any amount payable to the Lenders in
connection with this Agreement is unpaid, whichever is later, at which time this
Agreement shall terminate, it being expressly understood that the obligations of
the Company under Sections 3.1, 3.3 and 7.8 shall survive any termination of 
this Agreement.  Whenever in this Agreement any party is referred to, such
reference shall be deemed to include the successors and assigns of such party,
but no assignment or transfer (by operation of law or otherwise) of this
Agreement by the Company or any Borrowing Subsidiary or any of their rights or
duties hereunder may be made without the prior written consent of all of the
Lenders; and all covenants, promises and agreements by or on behalf of the
Company or any Borrowing Subsidiary which are contained in this Agreement shall
inure to the benefit of the successors and assigns of the Lenders.
        
     12.4 Fees and Expenses of the Lenders.

          The Company will pay (a) all reasonable out-of-pocket costs and
expenses incurred by the Agent or by the Collateral Agent (including the fees,
out-of-pocket expenses and other reasonable expenses of counsel to the Agent or
the Collateral Agent) in connection with the preparation, execution and delivery
of this Agreement, the Notes, the Security Agreement and any other agreements or
documents referred to herein or therein and any amendments thereto, and (b) all

     12.5 Applicable Law.

          This Agreement shall be construed in accordance with and governed by
the law of the State of Illinois.

     12.6 Modification of Agreement.

          Except for certain changes in a Lender's Commitment or admission of a
new Lender which (pursuant to Section 2.1) do not require any consents or
approvals from the other Lenders but which require a New/Modified Commitment
Supplement executed by the Agent, the Company, the Borrowing Subsidiaries and
the Lender(s) being added or modifying their Commitment, no provisions of this
Agreement may be amended or waived unless such amendment or waiver is in writing
and is signed by the Company, and the Agent if the rights or duties of the Agent
are affected thereby, and

          (1) each Lender if such amendment or waiver

               (i) reduces or forgives any principal of any unpaid Loan or any
          interest thereon or any Fees due to such Lender hereunder; or

               (ii) postpones the date fixed for any payment of principal of or
          interest on any unpaid Loan or any Fees payable to such Lenders; or

               (iii) changes the amount of payment of principal of or interest

               (iv) changes or waives any of the conditions precedent to the
          initial Advance hereunder or any subsequent Advance; or

<PAGE>   126
                        (x)    changes the definitions of Positive Security
                Event, Negative Security Event or Positive Security Conditions
                or waives compliance with any Positive Security Condition; or

                        (xi)   changes or waives any restriction on the
                Company's or any Borrowing Subsidiary's ability to assign its

                Lender; or

                        (xv)   changes the definition of Required Lenders or
                modifies any requirement for consent by all of the Lenders; or

                the allocation among the Lenders of any payments or proceeds
                received by the Agent hereunder; or

                (2)     the Required Lenders in the case of all other waivers
        or amendments.

        12.7    Non-Waiver of Rights by the Lenders.

                Neither any failure nor any delay on the part of the Agent or
the Lenders in exercising any right, power or privilege hereunder or under the
Security Agreement shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege.

        12.8    Dealings with the Company and its Affiliates.

                The Lenders and their Affiliates may accept deposits from,
extend credit to and generally engage in any kind of banking, trust or other
business with the Company and any of its Affiliates regardless of the capacity
of the Lenders hereunder.

        12.9    Changes in GAAP.

                The parties agree that if there are any changes in GAAP in the
future which result in material changes to the presentation of the Company's
financial condition in accordance with GAAP in such a way as to alter the
material intent of this
 
        




                                    116.4

<PAGE>   127
Agreement, then the parties will negotiate in good faith to attempt to agree on
such modifications to this Agreement as may be necessary to preserve the
original intent of this Agreement in light of such revised GAAP rules, provided
that unless and until a written agreement is entered into by all parties
hereto, no changes to this Agreement shall be effective and all calculations
required to be made in accordance with GAAP hereunder shall continue to be made
as if GAAP had not changed.

    12.10  Set-off.

         (a)  If an Event of Default shall have occurred, each Lender shall
    have the right, at any time and from time to time without notice to the
    Company or any Borrowing Subsidiary, any such notice being hereby expressly
    waived, to set-off and to appropriate or apply any and all deposits of money
    or property or any other indebtedness at any time held or owing by such
    Lender to or for the credit or the account of the Company or any Borrowing
    Subsidiary  against and on account of all outstanding Credit Indebtedness
    and all Credit Indebtedness which from time to time may become due
    hereunder and all other obligations and liabilities of the Company or any
    Borrowing Subsidiary under this Agreement, regardless of the adequacy of
    any Collateral and irrespective of whether or not such Lender shall have
    made any demand hereunder and whether or not said obligations and
    liabilities shall have matured.

         (b)  Each Lender agrees that if it shall, by exercising any right of
    set-off or counterclaim or otherwise, receive payment of a proportion of    
    the aggregate amount of principal, interest or Fees due with respect to
    this Agreement and the Notes held by it which is greater than the
    proportion received by any other Lender in respect of the aggregate amount
    of principal, interest or Fees due with respect to this Agreement and the
    Notes held by such other Lender, the Lender receiving such proportionately
    greater payment shall purchase such participations in the Notes held by the
    other Lenders and such other adjustments shall be made, as may be required
    so that all such payments of principal, interest or Fees shall be shared by
    the Lenders hereunder pro rata according to their respective shares of the
    Credit Indebtedness.  Each Lender agrees to exercise any and all rights of
    set-off, counterclaim or bankers' lien relating to the Credit Indebtedness
    first fully against the Credit Indebtedness and only then to any other Debt
    of the Company or any Borrowing Subsidiary to such Lender.  Neither the
    Company nor any Borrowing Subsidiary is a party to the agreement among the
    Lenders set forth in this Section 12.10 (b), and such Section may be
    amended without the consent of either the Company or any Borrowing
    Subsidiary.
        



                                    116.5
<PAGE>   128


          (c)   The Company and the Borrowing Subsidiaries agree that funds
     received and held by the Company or any Borrowing Subsidiary as
     custodian for FNMA, GNMA or other mortgage pools which are deposited into
     accounts with any Lender shall be clearly identified as custodial
     accounts, and each Lender agrees that each provision of the foregoing
     paragraphs of this Section 12.10 shall not apply to such custodial
     accounts.  Neither the Company nor any Borrowing Subsidiary shall deposit
     any of its general funds in any custodial accounts or otherwise commingle 
     funds in any custodial accounts. 

     12.11   Counterparts.

          This Agreement may be executed in  counterparts which, taken
together, shall constitute a single document.

     12.12   Severability.

          In case any one or more of the provisions contained in this Agreement
should be invalid, illegal or unenforceable in any respect, the validity,
legality and enforceability of the remaining provisions contained herein shall
not in any way be affected or impaired thereby.

     12.13   Headings.

          Section headings in the Credit Documents are for convenience of
reference only and shall not govern the interpretation of any of the provisions
of the Credit Documents. 

     12.14   Entire Agreement.

          The Credit Documents embody the entire agreement and understanding
among the Company, the Borrowing Subsidiaries, the Agent and the Lenders and
supersede all prior agreements and understandings among the Company, the
Borrowing Subsidiaries, the Agent and the Lenders relating to the subject
matter thereof.

     12.15   Limitation on Recourse to Borrowing Subsidiaries.

     Each Borrowing Subsidiary and the Company shall be jointly and severally
liable for the payment of the Obligations; provided, however, that recourse to
any particular Borrowing Subsidiary hereunder shall be limited to (i) such
Borrowing Subsidiary's interest in the Collateral pledged by such Borrowing
Subsidiary to the Agent or the Collateral Agent under the Credit Documents and
the proceeds thereof, plus (ii) an amount equal to the capital investment by
the Company in such Borrowing Subsidiary, plus (iii) an amount equal to the
total of all Debt owed by such Borrowing Subsidiary to the Company.

</TABLE>


The Applicable Margin for each Rate Option shall be the applicable percentage
per annum set forth above, which is based on the Company's long term unsecured
debt ratings, changing as and when such ratings change for Eurodollar Interest
Periods or Discount Periods commencing after the date of such change.  Each
rating classification sets forth the S&P rating and the Moody's rating,
respectively.  For the three columns noted with an asterisk (*), if on any day
the ratings of S&P and Moody's are not both at the required level, the higher
rating will be the applicable rating for purposes of determining the
classification unless the lower rating is more than one rating category below
the minimum rating for such rating agency under such column, in which event the
higher rating will be disregarded, the lower rating will be deemed to have been
one rating category higher than the actual reported lower rating, and the
column applicable using such deemed lower rating shall apply.  If for any
reason the Company's unsecured long term debt is not rated by both S&P and
Moody's, the column headed "Below either BBB- or Baa3" shall be used.

The Facility Fee Rate for this Facility shall be the applicable percentage per
annum set forth above, which is based on the Company's long term unsecured debt
ratings, changing as and when such ratings change.  Each rating classification
sets forth the S&P rating and the Moody's rating, respectively.  For the three
columns noted with an asterisk (*), if on any day the ratings of S&P and
Moody's are not both at the required level, the higher rating will be the
applicable rating for purposes of determining the classification unless the
lower rating is more than one rating category below the minimum rating for such
rating agency under such column, in which event the higher rating will be
disregarded, the lower rating will be deemed to have been one rating category
higher than the actual reported lower rating, and another column will be
applicable using such deemed lower rating.  If for any reason the Company's
unsecured long term debt is not rated by both S&P and Moody's, the column
headed "Below either BBB- or Baa3" shall be used.

              (FOR LOANS OTHER THAN DISCOUNT LOANS AND BID LOANS)


                                                     Date of Note: July __, 1997


         FOR VALUE RECEIVED, the undersigned (the "Makers") do hereby jointly
and severally covenant and promise to pay to the order of ____________________
(the "Lender") or its successors or assigns (collectively, the "Payee"), on the
Termination Date, the aggregate unpaid principal amount of all Loans made by
Lender pursuant to the Credit Agreement other than Discount Loans and Bid Loans
held from time to time by the Lender (the "Principal Amount") and to pay
interest on the unpaid Principal Amount at the applicable interest rate or
rates per annum determined in accordance with the terms of the Credit
Agreement.  All payments of principal of and interest on this Note shall be
made in legal tender of the United States.  All payments of principal of and
interest on this Note shall be made in immediately available funds at the
principal office of The First National Bank of Chicago (the "Agent"), One First
National Plaza, Chicago, Illinois.

         Interest on this Note shall be computed on the basis of actual number
of days elapsed in a 360 day year.

         This Note is one of the Notes referred to in the Third Amended and
Restated Revolving Credit Agreement, bearing even date herewith, among the
Company, the Borrowing Subsidiaries, the Lender and the other lenders listed on
the signature pages thereof and the Agent (as the same may be amended and
supplemented from time to time, the "Credit Agreement") and is entitled to the
benefits thereof.  Reference is made to the Credit Agreement for (i) provisions
for the prepayment hereof, (ii) acceleration of the maturity hereof, (iii) the
obligation of the Makers to pay certain expenses (including attorney's fees)
incurred in the enforcement thereof and hereof and (iv) a description of the
security for this Note.  Capitalized terms used herein without definition have
the respective meanings ascribed to them in the Credit Agreement.

         All Loans made by the Lender and all repayments of the principal
thereof shall be recorded by the Lender in its books and records; provided,
however, that the Lender's failure to so record or any error in such recording
shall not affect the Makers' liability hereunder or under the Credit Agreement.
Upon any transfer hereof, the Lender shall endorse on the schedule





                                     -127-

attached hereto or on a schedule accompanying the transfer of this Note, the
unpaid principal balance of this Note.

         If an Event of Default shall occur under the Credit Agreement, the
unpaid Principal Amount hereunder shall become due and payable (i)
automatically in the case of any of the Events of Default specified in
paragraph (k) of Section 10.1 of the Credit Agreement, or (ii) at the option of
the Required Lenders with respect to all other Events of Default and shall bear
interest at the rate provided for in Section 2.7 of the Credit Agreement from
and after such date.  The foregoing provision shall not be construed as a
waiver by the Payee of its right to pursue any other remedies available to it
under this Note, the Credit Agreement or any other instrument evidencing or
securing the Principal Amount.

         This Note may not be changed orally but only by an agreement in
writing, signed by the party against whom enforcement of any waiver, change,
modification or discharge is sought.  Written notices required to be given
hereunder shall be given as provided in the Credit Agreement to the Payee and
Makers at the respective addresses specified or provided for therein.

         Should the indebtedness evidenced by this Note or any part thereof be
collected at law or in equity, or in bankruptcy, receivership or any other
court proceeding (whether at the trial or appellate level), or should this Note
be placed in the hands of attorneys for collection upon default, the Makers
agree to pay, in addition to the principal, interest and other sums due and
payable hereon, all costs of collecting or attempting to collect on this Note,
including reasonable attorneys' fees and expenses.

         Notwithstanding the foregoing, recourse to any particular Borrowing
Subsidiary hereunder shall be limited to (i) such Borrowing Subsidiary's
interest in the Collateral pledged by such Borrowing Subsidiary to the Agent or
the Collateral Agent under the Credit Documents and the proceeds thereof plus
(ii) an amount equal to the capital investment by the Company in such Borrowing
Subsidiary, plus (iii) an amount equal to the total of all Debt owed by such
Borrowing Subsidiary to the Company.

         Anything herein to the contrary notwithstanding, the obligations of
the Makers under this Note shall be subject to the limitation that payments of
interest shall not be required to the extent that receipt of any such payment
by the Payee would be contrary to provisions of law applicable to Payee which
limit the maximum rate of interest that may be charged or collected by Payee.

         The undersigned and all endorsers, guarantors and sureties of this
Note and all other persons liable or to become liable on





                                     -128-

this Note severally waive presentment for payment, demand, notice of demand and
of dishonor and nonpayment of this Note, notice of intention to accelerate the
maturity of this Note, notice of acceleration of the maturity of this Note,
protest and notice of protest, diligence in collecting, and the bringing of
suit against any other party, and agree to all renewals, extensions,
modifications, partial payments, releases or substitutions of security, in
whole or in part, with or without notice, before or after maturity.

         Notwithstanding the foregoing paragraphs and all other provisions of
this Note and the Credit Agreement, none of the terms and provisions of this
Note or the Credit Agreement shall ever be construed to create a contract to
pay to the Payee, for the use, forbearance or detention of money, interest in
excess of the maximum amount of interest permitted to be charged by the Payee
to the undersigned under applicable state or federal law from time to time in
effect, and the undersigned shall never be required to pay interest in excess
of such maximum amount.  If, for any reason interest is paid hereon in excess
of such maximum amount, then promptly upon any determination that such excess
has been paid the Payee will, at its option, either refund such excess to the
undersigned or apply such excess to the principal owing hereunder.

         This Note is to be construed and enforced in accordance with the laws
of the State of Illinois.

         IN WITNESS WHEREOF, Makers have executed and delivered this Note on
the day and year first above written.

                                  EXHIBIT E-2

                   FORM OF AMENDED AND RESTATED DISCOUNT NOTE


                                                    Date of Note:  July __, 1997


         FOR VALUE RECEIVED, the undersigned (the "Makers") do hereby jointly
and severally covenant and promise to pay to the order of ____________________
(the "Lender") or its successors or assigns (collectively, the "Payee") the
unpaid principal amount of each Discount Loan made and retained by the Lender
(if the holder hereof is the Balance Bank initially making such discount Loan)
or, in all other cases, made by a Balance Bank and purchased by the holder
hereof (or its predecessor in interest) under the Credit Agreement (the
"Principal Amount"), on the last day of the Discount Loan Period applicable to
each such Discount Loan with a final payment of any such amounts not previously
due on the Termination Date.

         Each Discount Loan evidenced by this Note was funded to the Company at
a discount as provided in the Credit Agreement; accordingly, the unpaid
principal amount of each Discount Loan evidenced by this Note will bear no
interest hereunder until the last day of the Discount Loan Period applicable
thereto, and if such unpaid principal amount of such Discount Loan is not paid
in full on such day, such unpaid principal amount shall from and after such day
bear interest at the rate of interest set forth in Section 2.7 of the Credit
Agreement.  All payments of principal of and interest, if any, on this Note
shall be made in legal tender of the United States.  All payments of principal
of and interest on this Note shall be made in immediately available funds at
the principal office of The First National Bank of Chicago (the "Agent"), One
First National Plaza, Chicago, Illinois.

         Interest on this Note, if any, shall accrue, shall be computed on the
basis of actual number of days elapsed in a 360 day year.

         This Note is one of the Discount Notes referred to in the Third
Amended and Restated Revolving Credit Agreement, bearing even date herewith,
among the Company, the Borrowing Subsidiaries, the Lender and the other lenders
listed on the signature pages thereof and the Agent (as the same may be amended
and supplemented from time to time, the "Credit Agreement") and is entitled to
the benefits thereof.  Reference is made to the Credit Agreement for (i)
provisions for the prepayment hereof, (ii) acceleration of the maturity hereof,
(iii) the obligation of the Makers to pay certain expenses (including
attorney's fees) incurred in the enforcement thereof and hereof and (iv) a





                                     -132-
<PAGE>   155

description of the security for this Note.  Capitalized terms used herein
without definition have the respective meanings ascribed to them in the Credit
Agreement.

         All Discount Loans made by the Lender and all repayments of the
principal thereof shall be recorded by the Lender in its books and records;
provided, however, that the Lender's failure to so record or any error in such
recording shall not affect the Makers' liability hereunder or under the Credit
Agreement.  Upon any transfer hereof, the Lender shall endorse on the schedule
attached hereto or on a schedule accompanying the transfer of this Note, the
unpaid principal balance of this Note.

         If an Event of Default shall occur under the Credit Agreement, the
unpaid Principal Amount hereunder shall become due and payable (i)
automatically in the case of any of the Events of Default specified in
paragraph (k) of Section 10.1 of the Credit Agreement, or (ii) at the option of
the Required Lenders with respect to all other Events of Default and shall bear
interest at the rate provided for in Section 2.7 of the Credit Agreement from
and after such date.  The foregoing provision shall not be construed as a
waiver by the Payee of its right to pursue any other remedies available to it
under this Note, the Credit Agreement or any other instrument evidencing or
securing the Principal Amount.

         This Note may not be changed orally but only by an agreement in
writing, signed by the party against whom enforcement of any waiver, change,
modification or discharge is sought.  Written notices required to be given
hereunder shall be given as provided in the Credit Agreement to the Payee and
Makers at the respective addresses specified or provided for therein.

         Should the indebtedness evidenced by this Note or any part thereof be
collected at law or in equity, or in bankruptcy, receivership or any other
court proceeding (whether at the trial or appellate level), or should this Note
be placed in the hands of attorneys for collection upon default, the Makers
agree to pay, in addition to the principal, interest and other sums due and
payable hereon, all costs of collecting or attempting to collect on this Note,
including reasonable attorneys' fees and expenses.

         Notwithstanding the foregoing, recourse to any particular Borrowing
Subsidiary hereunder shall be limited to (i) such Borrowing Subsidiary's
interest in the Collateral pledged by such Borrowing Subsidiary to the Agent or
the Collateral Agent under the Credit Documents and the proceeds thereof plus
(ii) an amount equal to the capital investment by the Company in such Borrowing





                                     -133-
<PAGE>   156

Subsidiary, plus (iii) an amount equal to the total of all Debt owed by such
Borrowing Subsidiary to the Company.

         Anything herein to the contrary notwithstanding, the obligations of
the Makers under this Note shall be subject to the limitation that payments of
interest shall not be required to the extent that receipt of any such payment
by the Payee would be contrary to provisions of law applicable to Payee which
limit the maximum rate of interest that may be charged or collected by Payee.

         The undersigned and all endorsers, guarantors and sureties of this
Note and all other persons liable or to become liable on this Note severally
waive presentment for payment, demand, notice of demand and of dishonor and
nonpayment of this Note, notice of intention to accelerate the maturity of this
Note, notice of acceleration of the maturity of this Note, protest and notice
of protest, diligence in collecting, and the bringing of suit against any other
party, and agree to all renewals, extensions, modifications, partial payments,
releases or substitutions of security, in whole or in part, with or without
notice, before or after maturity.

         Notwithstanding the foregoing paragraphs and all other provisions of
this Note and the Credit Agreement, none of the terms and provisions of this
Note or the Credit Agreement shall ever be construed to create a contract to
pay to the Payee, for the use, forbearance or detention of money, interest in
excess of the maximum amount of interest permitted to be charged by the Payee
to the undersigned under applicable state or federal law from time to time in
effect, and the undersigned shall never be required to pay interest in excess
of such maximum amount.  If, for any reason interest is paid hereon in excess
of such maximum amount, then promptly upon any determination that such excess
has been paid the Payee will, at its option, either refund such excess to the
undersigned or apply such excess to the principal owing hereunder.

         This Note is to be construed and enforced in accordance with the laws
of the State of Illinois.

         IN WITNESS WHEREOF, Makers have executed and delivered this Note on
the day and year first above written.

                                   EXHIBIT F

             METHOD OF DETERMINING WEIGHTED AVERAGE PURCHASE PRICES


STEP ONE

Group Mortgage Loans or Securities into the following categories (or such other
categories as are agreed upon among the Company, the Agent and the Collateral
Agent):

         GNMA 15              FNMA/FHLMC 15                  Private
         GNMA 30              FNMA/FHLMC 30                   Investors
         GNMA ARM             FNMA/FHLMC ARM
                              FNMA/FHLMC Balloon
                              Non-Conforming
                              Jumbo

STEP TWO - WEEKLY

Allocate Approved Investor Commitments (other than those allocated to repos)
under which the applicable Mortgage Loans or Securities could be settled to
each mortgage-type category on a FIFO basis.  The dollar amount of Approved
Investor Commitments allocated should cover the maximum amount of Mortgage
Loans or Securities for which the Company expects to borrow in the following
week.  If the mortgage balances exceed the allocated Approved Investor
Commitments on any day, a re-allocation should be calculated.

After allocating Approved Investor Commitments, compute the weighted average
price of the Approved Investor Commitments.  This is the price to be allocated
to Securities or the unpaid principal balance of Mortgage Loans, as applicable,
in each category for any borrowing in the next week.  Approved Investor
Commitments may not be allocated to Mortgage Loans unless the related coupons
net of servicing and guaranty fees equal or exceed the contract coupon
requirement.

AT THE REQUEST OF THE CREDIT AGENT, THE FOLLOWING FURTHER STEPS SHALL BE TAKEN
WHEN COMPUTING THE WEIGHTED AVERAGE PURCHASE PRICES.

STEP THREE - MARK TO MARKET FORWARD PURCHASE CONTRACTS

Calculate the value of all unallocated mandatory delivery forward purchase
contracts.  Compute a net negative or positive amount to be added to or
subtracted from the aggregate market value of all collateral.  Use the
following method:





                                     -137-
<PAGE>   160

AGENCY SECURITY CONTRACT

Find the Telerate (or other recognized electronic service) purchase (offer)
price for same coupon, type, and delivery date as stated on the Company's
forward purchase contract.  Subtract the Company's contract price from the
Telerate price and multiply by the dollar amount of the contract.  A positive
number is a deduction, and a negative number is an addition to aggregate market
value.

OTHER CONTRACTS

Unallocated Whole Loan Contracts:

Use the above method but use the weighted average posted prices of two
nationally recognized private mortgage conduits mutually acceptable to the
Collateral Agent and the Company for similar mortgages, coupon (net of
servicing fees) and delivery date.

Private Label Securities Forward Purchase Contracts:

Use the same method but the current contract price should be based on quotes of
two nationally recognized dealers in private label mortgage- backed securities
for the same forward delivery date as the contract.

If no Telerate price is posted for a particular agency or whole loan coupon,
the posted price associated with the nearest lower coupon should be used.  If
the contract coupon is below the lowest Telerate coupon then the price should
be based on quotes of two nationally recognized dealers in mortgage-backed
securities for the same forward delivery date as the contract.

                         FORM OF TRANSITION MEMORANDUM


         This TRANSITION MEMORANDUM is dated as of July __, 1997, by and
between Source One Mortgage Services Corporation, a Delaware corporation (the
"Company"), The Mortgage Authority, a Delaware corporation ("TMA"), Central
Pacific Mortgage Company, a California corporation ("CPMC") and The First
National Bank of Chicago, as agent ("Agent") for the Existing Lenders and for
the Continuing Lenders (as such terms are hereinafter defined).

         The Company and the Borrowing Subsidiaries have entered into a certain
Third Amended and Restated Revolving Credit Agreement dated as of July __, 1997
(the "Credit Agreement") with the lenders named therein and the Agent.  The
lenders under the Credit Agreement are hereinafter referred to collectively as
the "Continuing Lenders".  Pursuant to the Credit Agreement the Continuing
Lenders will agree to extend credit to the Company and the Borrowing
Subsidiaries through a revolving credit facility (the "New Facility") on the
terms and subject to the conditions set forth therein.  Capitalized terms not
otherwise defined herein are used with the same meanings as in the Credit
Agreement.

         The New Facility amends and restates existing revolving credit
facility provided to the Company, TMA, or CPMC (the "Existing Facility") made
available pursuant to that certain Second Amended and Restated Revolving Credit
Agreement dated as of November 12, 1996 (as amended, the "Existing Agreement"),
by and among the Company, TMA, CPMC, the Agent and the lenders participating
therein (each an "Existing Lender").

         Certain of the Existing Lenders are not Continuing Lenders under the
New Facility (the "Exiting Lenders").  In addition, pursuant to the Credit
Agreement (i) certain of the Existing Lenders will have a percentage of the
Aggregate Commitment under the New Facility that differs from their percentage
under the Existing Facility, and (ii) certain Continuing Lenders joining the
New Facility are not Existing Lenders.

         The purpose of this Transition Memorandum is to set forth an
understanding of certain matters concerning the transition by the Company from
the Existing Facility to the New Facility, such matters including, without
limitation, (i) the payment of all the outstanding Loans (as defined in the
Existing Agreement and hereinafter referred to as the "Existing Loans") to the
Exiting Lenders, (ii) the changes necessary in the percentage of the Advances
under the Credit Agreement held by the Continuing Lenders, and (iii) the
initial fundings of Advances by the Continuing Lenders which are not Existing
Lenders.

<PAGE>   175


         1.      Summary of Existing Loans.  The initial Advance under the New
Facility shall be used to pay any Existing Loans held by the Exiting Lenders.
Prior to the date the conditions precedent set forth in Article 5 of the Credit
Agreement are satisfied (such date being the "Effective Date"), the Agent shall
identify the Existing Loans payable by the Company under the Existing
Agreements to each Exiting Lender and advise the Continuing Lenders of such
amount.  The aggregate outstanding balance of the Existing Loans held by the
Exiting Lenders on the Effective Date shall be hereinafter referred to as the
"Exiting Lender Pay-Off Amount".

         2.      Initial Advance.  Subject to the terms and conditions set
forth in the Credit Agreement, including, without limitation, satisfaction of
the conditions precedent set forth in Article 5 therein, the Continuing Lenders
will make an initial Advance to the Company on the Effective Date in an amount
equal to the Exiting Lender Pay-Off Amount.  The initial Advance shall be based
upon an Advance Notice and shall consist of such types of Advances specified in
such Advance Notice.  Each Continuing Lender will agree to make its share of
such Advance available to the Agent at such time and in such amount as provided
in the Credit Agreement as modified by Paragraphs 3 and 4 below.

         3.      Conversion of Loans.  With respect to each Continuing Lender,
to the extent that such lender has an Existing Loan outstanding on the date of
the initial Advance, such Continuing Lender shall only be required to fund to
the Agent an amount (the "Net Funding Amount") equal to the excess, if any, of
that amount by which the aggregate amount of its Loans to be outstanding under
the New Facility on the Effective Date exceeds the aggregate amount of its
Existing Loans (excluding any accrued and unpaid interest, Fees and other
charges or expenses thereon).  After making its Net Funding Amount available to
the Agent, such Continuing Lender shall be deemed to have made available all of
its Loans under the New Facility and shall be deemed to have converted its
Existing Loans (excluding any accrued and unpaid interest and other charges or
expenses thereon).  To the extent that a Continuing Lender has Existing Loans
in an amount which exceeds the amount of its Loans to be outstanding under the
New Facility on the Effective Date, such Lender shall be deemed to have made
available all of its Loans under the New Facility required to be made on the
Effective Date and shall be repaid a portion of its Existing Loans equal to
such excess amount, if any, as provided in Paragraph 4.  All Existing Loans
held by Continuing Lenders which are outstanding on the Effective Date and not
repaid shall continue as the same type of Loan under the New Facility until
repaid or converted in accordance with the terms of the Credit Agreement;
provided that from and after the Effective Date such Existing Loans shall bear
interest at the





                                     -153-
<PAGE>   176

interest rates applicable under the Credit Agreement rather than the rates
applicable under the Existing Agreements.

         4.      Percentage Reconciliation.  If any Continuing Lender holds
Existing Loans (other than Bid Loans) on the Effective Date which are in excess
of such Continuing Lender's Adjusted Commitment Percentage of the Loans (other
than Bid Loans and Swingline Loans) to be outstanding under the New Facility
(an "Overfunded Lender") on the Effective Date, such Overfunded Lender shall be
repaid from the additional funding under the following sentence an amount of
Existing Loans sufficient to eliminate such excess.  Each Continuing Lender
(including any Continuing Lender which is not an Existing Lender) that holds
Existing Loans in an amount less than such Continuing Lender's Adjusted
Commitment Percentage of the Loans (other than Bid Loans and Swingline Loans)
to be outstanding under the New Facility on the Effective Date (an "Underfunded
Lender") shall make an additional funding as a Federal Funds Loan in connection
with the initial Advance in an amount sufficient to eliminate such shortfall
(such additional funding being collectively referred to as "Percentage
Reconciliation Funding Amount").

         5.      Distribution of Initial Advance.  After each Continuing Lender
has funded its Loan (or so much of such Loan as may be required pursuant to
Paragraphs 3 and 4 above), the Agent shall (i) distribute to each Exiting
Lender its Exiting Lender Pay-Off Amount in accordance with the Existing
Agreements and (ii) distribute to each Overfunded Lender its share of the
aggregate Percentage Reconciliation Funding Amount.

         6.      Payment of Accrued Interest and Fees; Indemnification.  On the
Effective Date the Company shall pay to the Agent for distribution to each
Exiting Lender all accrued interest and Fees owing to such Lender for its
Existing Loans.  To the extent of its obligations under the Existing Agreement,
the Company shall pay each Exiting Lender for all reasonable losses, costs and
expenses incurred by such Exiting Lender in connection with any prepayment of
its Existing Loans in accordance with the terms of the Existing Agreement.

         7.      Termination of Commitments under Existing Facility.  On the
Effective Date the commitments of the Lenders (as defined in the Existing
Agreement) under the Existing Facility shall terminate and the Lenders therein
shall have no further obligation to make any further Loans (as defined in the
Existing Agreement) under the Existing Facility.

         8.      No Modification.  It is understood and agreed to by the
parties hereto that, except as expressly set forth above, nothing in this
memorandum shall modify or amend the covenants, terms and agreements set forth
in the Existing Agreement or the documents related thereto or in the Credit
Agreement and the other Credit





                                     -154-

Documents, or discharge the obligations of (a) the Company, TMA, the Existing
Lenders and the Agent under the Existing Agreement, and (b) the Company, the
Borrowing Subsidiaries, the Continuing Lenders and the Agent under the Credit
Agreement.

                           THIRD AMENDED AND RESTATED
                    SECURITY AND COLLATERAL AGENCY AGREEMENT


         THIS THIRD AMENDED AND RESTATED SECURITY AND COLLATERAL AGENCY
AGREEMENT (the " Security Agreement") is made and dated as of July 25, 1997, by
and among SOURCE ONE MORTGAGE SERVICES CORPORATION, a Delaware corporation (the

PACIFIC MORTGAGE COMPANY, a California corporation ("CPM"), THE FIRST NATIONAL
BANK OF CHICAGO, a national banking association, acting in its capacity as
administrative agent for the lenders from time to time participating in the
Credit Agreement (as defined below) (in such capacity, the "Credit Agent"), and
NATIONAL CITY BANK OF KENTUCKY, a national banking association, as collateral
agent for the Secured Parties (as defined below) (in such capacity, the
"Collateral Agent").


                                    RECITALS

         A.      This Third Amended and Restated Security and Collateral Agency
Agreement amends and restates in its entirety that certain Second Amended and
Restated Security and Collateral Agency Agreement dated as of November 12, 1996
(the "Second Amended Agreement"), by and among the parties hereto and Norwest
Bank Minnesota, N.A., as the Successor Trustee under the Indentures (as defined
in the Second Agreement).

         B.      Pursuant to that certain Third Amended and Restated Revolving
Credit Agreement of even date herewith (the "Credit Agreement"), the Lenders
agreed to extend credit to the Company, TMA and CPM on the terms and subject to
the conditions set forth therein.  The Credit Agreement amends and restates in
its entirety that certain Second Amended and Restated Revolving Credit
Agreement dated as of November 12, 1996 by and among the Company, TMA, CPM,

         C.      TMA and CPM (each a "Borrowing Subsidiary") are wholly-owned

constitute a portion of the Collateral.

         D.      As a condition precedent to the effectiveness of the Credit

Security Agreement in order to, among other things, create a first priority
perfected security interest in the Collateral in favor of the Lenders, the
Non-Lender Balance Banks (to the extent of any Credit Indebtedness owed to such
Non-Lender Balance Banks), the Credit Agent and the Collateral Agent,
(collectively, the "Secured Parties") to secure payment of the Credit
Indebtedness (the "Secured Debt").

         NOW, THEREFORE, in consideration of the above Recitals and for other
good and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the parties hereto agree as follows:

                                   AGREEMENTS

       1.        Appointment of Collateral Agent.  Each Lender and Non-Lender
Balance Bank has, pursuant to the terms of the Credit Agreement, appointed the
Collateral Agent to act as secured party, agent, bailee and custodian for the
exclusive benefit of the Secured Parties with respect to the Collateral.  The
Collateral Agent hereby accepts such appointment and agrees to maintain and
hold, or cause to be maintained and held, all Collateral at any time delivered
to it or any of its subagents as secured party, agent, bailee and custodian for
the exclusive benefit of the Secured Parties.  The Collateral Agent, the
Borrowing Subsidiaries and the Company agree that the Collateral Agent is
acting and will act with respect to the Collateral for the exclusive benefit of
the Secured Parties and is not, and shall not at any time in the future be,
subject, with respect to the Collateral, in any manner or to any extent, to the
direction or control of the Company or any Borrowing Subsidiary except as
expressly permitted hereunder and under the other Credit Documents.  The
Collateral Agent agrees to act in accordance with this Security Agreement and
in accordance with any written instructions properly delivered pursuant hereto.
Under no circumstances shall the Collateral Agent deliver, or cause to be
delivered, possession of Collateral to the Company or any Borrowing Subsidiary
except in accordance with the express terms of this Security Agreement or the
other Credit Documents.

       2.        Delivery and Categorization of Collateral.

                 (a)      Mortgage Loans.  The Company and each Borrowing
Subsidiary (each such entity, with respect to any Pledged Item owned by such
entity, is referred to herein as the "Pledgor") shall deliver Collateral
Transmittals to the Collateral Agent from time to time identifying Mortgage
Loans that the Pledgor intends to include in Collateral by delivering to the
Collateral Agent the Required Mortgage Documents (as described on Schedule A
attached hereto) for such Mortgage Loans.  Such delivery shall be made prior to
inclusion of such Mortgage Loans in Collateral, other than for AP Mortgages
identified in the Collateral Transmittal and covered by an AP Notice.  The
Collateral Agent shall review the Required Mortgage Documents in accordance
with the review steps described on Exhibit 1 hereto.

                 (b)      AP Notices.  The Collateral Agent, upon receipt of a
Collateral Transmittal describing the AP Mortgages to be covered by an AP
Notice and an AP Notice as of that date, shall (subject to the eligibility
requirements set forth in the Credit Agreement) include such AP Mortgages as
Eligible Collateral in the Collateral Value Determination (as defined Paragraph
6(a) below).  The Pledgor shall deliver the Required Mortgage Documents for
each such AP Mortgage not later than the tenth (10th) Business Day after the
date such AP Mortgage is first so included as an Eligible AP Mortgage.  If the
Required Mortgage Documents for any AP Mortgage are not delivered by such 10th
Business Day, the Credit Agent or the Collateral Agent may request that the
Pledgor advise the Collateral Agent and the Credit Agent in writing of the
specific reason that such Required Mortgage Documents were not delivered, and
the Pledgor shall so advise the Collateral Agent and the Credit Agent within 30
days after such request.

                 (c)      Securities.  The Pledgor may, from time to time,
deliver Securities to the Collateral Agent or an Approved MBS Custodian and
shall provide such evidence that such Securities are either (a) in a
certificated form, with the certificates evidencing such Securities being
delivered to the Collateral Agent or such Approved MBS Custodian, or (b) in
book entry or uncertificated form with evidence that the Collateral Agent or
such Approved MBS Custodian has been identified as the nominal owner of such
Securities in the records of a Federal Reserve Bank or other institution
authorized by the applicable Federal Agency to maintain





                                      -3-
<PAGE>   4

ownership records in respect of such Securities.

                 (d)      Repurchased Agency Loans and Receivables.  The
Company shall identify Repurchased Agency Loans and Receivables from time to
time by providing a list of such items to the Collateral Agent.  Such list
shall include statements indicating (i) the identification number of each such
Mortgage Loan, (ii) its unpaid principal balance, (iii) the "paid-to" date for
such Mortgage Loan, (iv) the date on which such Mortgage Loan was purchased by
the Company out of the applicable pool, (v) whether or not such Mortgage Loan
has been reinstated and the payment defaults thereunder cured by the mortgagor,
(vi) the date on which any foreclosure sale with respect to such Mortgage Loan
has occurred, (vii) the status of the related claim against the VA or FHA or
HUD, and (viii) whether the borrower of the Mortgage Loan filed a voluntary
bankruptcy petition or had an involuntary bankruptcy petition filed against it
while the payments on such Mortgage Loan were past due.  The Company shall
provide a weekly update of such information to the Collateral Agent by 5:00
p.m. (Chicago time) on the last Business Day of each week with regard to any
Repurchased Agency Loans and Receivables previously identified as being
included in Collateral, which update shall be as of the close of business on
the second to last Business Day of such week, and which information shall be
used for Collateral Value Determinations during the following week.  The
Collateral Agent shall have the right at any time at the direction of the
Aggregate Required Lenders, to require the Company to submit all Required
Mortgage Documents and item number 4 from the Additional Required Mortgage
Documents for any Repurchased Agency Loan and Receivable then being included in
Collateral, and the Collateral Agent shall request the submission of such
documents at the direction of the Credit Agent.  In addition, the Company shall
provide, at the request of the Collateral Agent or the Credit Agent, claim
forms to FHA or VA or HUD for each such Repurchased Agency Loan and Receivable,
identifying the Collateral Agent as the "investor" thereunder so that any
payments made by FHA or VA or HUD with respect to such Mortgage Loan shall be
paid to the Collateral Agent rather than the Company.  In addition, with
respect to those Repurchased Agency Loans and Receivables for which there has
been a foreclosure sale of the underlying property, the Credit Agent shall have
the right to require the Company to provide a new mortgage in favor of the
Collateral Agent on the real estate and improvements that previously secured
such Repurchased Agency Loan and Receivable, all





                                      -4-
<PAGE>   5

in form satisfactory to the Credit Agent and Collateral Agent and at the
Company's sole cost and expense, including the cost of recording such mortgage
if required by the Credit Agent.

                 (e)      Servicing Sale Receivables.  The Company may, in
connection with a sale of Servicing Agreements from the Company to a Servicing
Purchaser, pledge the Servicing Sale Receivables due in connection with such
sale to the Collateral Agent as Collateral.  If the Company so pledges
Servicing Sale Receivables to the Collateral Agent, the Company shall (i)
deliver to the Credit Agent and the Collateral Agent a complete executed copy
of the related purchase agreement and written confirmation from the Servicing
Purchaser as to the amount of such Pledged Servicing Sale Receivables, (ii)
assign its rights to such Pledged Servicing Sale Receivables to the Collateral
Agent for the benefit of the Secured Parties pursuant to an assignment in form
and content satisfactory to the Required Lenders, and (iii) cause the Servicing
Purchaser of the applicable sold Servicing Agreements to execute an agreement
in form and content satisfactory to the Required Lenders pursuant to which the
Servicing Purchaser shall agree to (A) pay such Pledged Servicing Sale
Receivables directly to the Collateral Agent for the benefit of the Secured
Parties, and (B) provide simultaneous written notice to the Credit Agent and
the Collateral Agent of any claims made against or notices given to the Company
which would constitute an offset to or reduction in the amount of such Pledged
Servicing Sale Receivables.

                 (f)      Identification of Collateral.  All Mortgage Loans and
Securities at any time delivered to the Collateral Agent hereunder shall be
held by the Collateral Agent in a fire resistant vault, drawer or other
suitable depositary maintained in accordance with Federal Agency standards and
controlled solely by the Collateral Agent, conspicuously marked to show the
respective interests of the Secured Parties therein and not commingled with any
other assets or property of, or held by, the Collateral Agent.  Accordingly, if
(pursuant to Paragraph 7(b) below) the Collateral Agent receives a shipping
request pursuant to which National City Bank of Kentucky is to retain physical
possession of the applicable Mortgage Loans or Securities as an agent for any
Person other than the Secured Parties, the Collateral Agent shall physically
separate such Mortgage Loans or Securities from the remainder of the Collateral
and shall execute any transmittal letters required under Paragraph 7(b) below.





                                      -5-

       3.        Grant of Security Interest.  The Company, with respect to
Collateral owned by the Company, and each Borrowing Subsidiary, with respect to
Collateral owned by the applicable Borrowing Subsidiary, hereby pledges,
assigns and grants to the Collateral Agent for the benefit of the Secured
Parties, a first priority security interest in the property described in
Paragraph 4 below (collectively and severally, the "Collateral"), to secure
payment of the Secured Debt.  Furthermore, each AP Notice shall create a
security interest in favor of the Collateral Agent for the benefit of the
Secured Parties in the AP Mortgages identified therein.  By delivering an AP
Notice, the Company represents and warrants that each AP Mortgage identified
therein constitutes an Eligible AP Mortgage.  The Company agrees that while it
is in possession of any Required Mortgage Documents for an AP Mortgage, it will
hold same in trust and as agent and bailee for the Collateral Agent for the
benefit of the Secured Parties, without authority to make any other disposition
thereof, or of the proceeds thereof.  The Company assumes the responsibility
for loss or destruction of any such Required Mortgage Documents until the same
are delivered to the Collateral Agent.

         Unless so directed by the Credit Agent when an Event of Default has
occurred and is continuing, the Collateral Agent shall not record the
assignment of mortgage or deed of trust delivered in connection with any
Pledged Mortgage.

       4.        Collateral.  The Collateral shall consist of all right, title
and interest of the Company and the Borrowing Subsidiaries, as applicable, of
every kind and nature, in and to all of the following property, assets and
rights of the Company and the Borrowing Subsidiaries wherever located, whether
now existing or hereafter arising, and whether now or hereafter owned or
acquired by or accruing or owing to the Company or a Borrowing Subsidiary, and
all proceeds and products thereof (including all proceeds in the Settlement
Account and Custodian Settlement Accounts from time to time):

                 (a)      all Pledged Mortgages;

                 (b)      all Pledged Securities;

                 (c)      any commitments or other agreements issued by any
private mortgage insurer or by the FHA or VA to insure or guarantee





                                      -6-
<PAGE>   7

any Pledged Mortgage;

                 (d)      all commitments of FNMA, FHLMC or other Persons to
purchase Pledged Items from the Company or any Borrowing Subsidiary or exchange
Securities with the Company or any Borrowing Subsidiary for Pledged Items;

                 (e)      any options to sell or purchase Securities, future
contracts, or any other interest rate protection products which directly or
indirectly protect the Company or any Borrowing Subsidiary against reductions
in value of such Pledged Items due to changes in mortgage interest rates;

                 (f)      the Settlement Account and any Custodian Settlement
Accounts and any amounts standing to the credit of the Settlement Account and
any Custodian Settlement Accounts then in existence with Approved MBS
Custodians, as described in Paragraph 7(c) of this Security Agreement;

                 (g)      all VA Mortgage Loans or FHA Mortgage Loans (plus any
REO or accounts receivable from FHA or VA resulting therefrom, including
guaranty claims against VA and insurance claims against FHA or HUD) which are
repurchased by the Company from Security holders and pledged to the Collateral
Agent as security for the Secured Debt;

                 (h)      all cash and Cash Equivalents held by the Credit
Agent or Collateral Agent as security for the Secured Debt;

                 (i)      all Pledged Servicing Sale Receivables; and

                 (j)      all property and proceeds related to the foregoing,
including without limitation, the right to service Pledged Mortgages while
owned by the Company or any Borrowing Subsidiary, all files, surveys,
certificates, correspondence, appraisals, computer programs, tapes, disks,
cards, accounting records and other records and data of the Company related to
the Pledged Mortgages, all accounts and general intangibles of whatsoever kind
so related and all documents or instruments delivered to the Credit Agent or
the Collateral Agent in respect of any Pledged Item, including, without
limitation, the right to receive all insurance proceeds and condemnation awards
which may be payable in respect of the premises encumbered by any Pledged
Mortgage.

       5.        Collateral Agent's Review of Collateral.  Upon any receipt of
Required Mortgage Documents for any Mortgage Loan, the Collateral Agent shall
review the same and verify that:

                 (a)      All Required Mortgage Documents relating to such
Mortgage Loan appear regular on their face (as determined by the Collateral
Agent in its reasonable discretion) and are in the Collateral Agent's
possession; and

                 (b)      The statements set forth on Exhibit 1 hereto are
accurate and complete in all material respects.

If the Collateral Agent notes any exception in the review described in
subparagraph (a) or (b) above or questions, in its reasonable discretion, the
genuineness, regularity, propriety, or accuracy of any item of Collateral, the
Collateral Agent shall not include such item as Eligible Collateral in its next
Collateral Value Determination (as defined in Paragraph 6(a) below) delivered
to the Credit Agent.  In the event that the Pledgor has been requested by the
Credit Agent or the Collateral Agent to deliver the "Additional Required
Mortgage Documents" (as described on Schedule B attached hereto) with respect
to any Mortgage Loan, the Collateral Agent shall review and verify such
Additional Required Mortgage Documents consistent with the obligations of the
Collateral Agent above.

       6.        Collateral Value Determination; Determination Assumptions.

                 (a)      On each Business Day the Collateral Agent shall
compute the value of the Borrowing Base and notify the Credit Agent thereof (a
"Collateral Value Determination") by sending a facsimile copy or electronic
transmission of a report ("Borrowing Base Report") in the form of Schedule C
hereto (or such other form as may be mutually agreed to by the Collateral Agent
and the Credit Agent) prior to 11:00 a.m. (Chicago time).  With respect to any
Required Mortgage Documents delivered to the Collateral Agent by 10:00 a.m.
(Chicago time) on any Business Day, the Collateral Agent shall review such
Required Mortgage Documents in the manner set forth in Paragraph 5 above in
time to include the related Mortgage Loans (to the extent they constitute
Eligible Collateral) in the Borrowing Base Report delivered at 11:00 a.m.
(Chicago time) on such Business Day.  If the Company or the Credit Agent
reasonably believes that the value of the Borrowing Base has changed since the





                                      -8-
<PAGE>   9

11:00 Borrowing Base Report, the Collateral Agent shall, at the request of the
Company or the Credit Agent made by facsimile prior to 2:00 p.m.  (Chicago
time) on any Business Day, recompute the Borrowing Base and notify the Credit
Agent thereof by telephone and by a facsimile transmission of a Borrowing Base
Report.  Notwithstanding the foregoing, so long as the security interest in the
Collateral is abated as described in Paragraph 8, the Company shall perform all
of the obligations of the Collateral Agent with respect to determining the
Borrowing Base, and the Collateral Agent shall have no duty to compute the
Borrowing Base or submit Borrowing Base Reports.

                 (b)      In making any Collateral Value Determination or other
calculation involving a determination of the value of the Borrowing Base, the
Collateral Agent shall be permitted to rely, without independent investigation
of the correctness thereof, on:

                          (1)     The information supplied by the Pledgor to
         the Collateral Agent on the related Collateral Transmittal, with
         respect to the net acquisition cost (including any discounts and
         excluding any servicing released premium) of any Mortgage Loan, the
         unpaid principal balance of any Mortgage Loan as of the Pledge Date
         therefor, and the weighted average purchase price (expressed as a
         percentage of par) committed to under those Approved Investor
         Commitments which could cover such Mortgage Loan;

                          (2)     The most recent information supplied by the
         Company to the Collateral Agent with respect to (i) the number of days
         by which payments on any Mortgage Loan constituting Collateral are
         past due, (ii) the date of any foreclosure sale or transfer in lieu of
         foreclosure with respect to a repurchased Mortgage Loan constituting a
         Repurchased Agency Loan and Receivable, (iii) the date of any
         reinstatement of any Repurchased Agency Loans and Receivables, (iv)
         the value of any REO and accounts receivable (including proceeds of
         FHA insurance or VA guaranties) acquired in connection with a
         foreclosure sale or a transfer in lieu of foreclosure of Eligible
         Repurchased Agency Loans and Receivables, and (v) whether the borrower
         of any Mortgage Loan which is included in Repurchased Agency Loans and
         Receivables filed a voluntary bankruptcy petition or had an
         involuntary bankruptcy petition filed against it while the payments on
         such Mortgage Loan were





                                      -9-
<PAGE>   10

         past due;

                          (3)     The information supplied by the Company to
         the Collateral Agent, whether written or in any other form acceptable
         to the Collateral Agent, with respect to a determination as to whether
         amounts received in the Settlement Account represent the purchase
         price paid for a specific Mortgage Loan or Security and, consequently,
         whether the Mortgage Collateral Value of such Mortgage Loan or MBS
         Value of such Security should be removed from such calculation;

                          (4)     The most recent information supplied by the
         Credit Agent to the Collateral Agent with respect to (i) the amount of
         the then current Aggregate Commitment, and (ii) the current balance in
         the Settlement Account;

                          (5)     The most recent information supplied by the
         Company and the Servicing Purchaser(s) to the Collateral Agent with
         respect to the amount of Servicing Sale Receivables; and

                          (6)     Any information supplied by the Credit Agent,
         the Company, or any other custodian of any of the Collateral, to the
         Collateral Agent unless the Collateral Agent has actual knowledge that
         such information is untrue or unreliable.

                 Furthermore, the Collateral Agent may rely on information
supplied by the Company with respect to the effect of the Borrowing Base
Sublimits on the value of the Borrowing Base attributable to Repurchased Agency
Loans and Receivables, which information shall be supplied by the Company on
the last Business Day of each week with respect to the value of the Borrowing
Base attributable to Repurchased Agency Loans and Receivables as of the close
of the second to last Business Day of such week which information shall be used
by Collateral Agent beginning with the first Collateral Value Determination
made during the following week; provided, however, that the Collateral Agent
shall (on the last Business Day of each month) verify the accuracy of the
information supplied by the Company in the most recent report of such
information and report to the Credit Agent any discrepancies between such
information as supplied by the Company and such information as calculated by
the Collateral Agent.  The information as calculated by the Collateral Agent
shall be included in each daily Borrowing Base Report until the Company again
provides its next weekly report of the value of





                                      -10-
<PAGE>   11

the Borrowing Base attributable to Repurchased Agency Loans and Receivables.

                 (c)      The Collateral Agent is hereby authorized by the
Credit Agent to grant temporary waivers of strict compliance by the Company
with the eligibility requirements regarding qualification of any item of
Collateral as Eligible Collateral or with the Borrowing Base Sublimits when the
Collateral Agent deems it appropriate, in its sole discretion, (i) up to any
amount for up to three (3) Business Days, if the satisfaction of such
eligibility requirements or sublimits cannot be independently determined
because of events beyond the reasonable control of the Company (e.g. natural
disasters, transmission failures, etc.), provided that, if such determination
cannot be made for more than one (1) Business Day, the Company certifies in
writing that all such eligibility requirements and sublimits are in fact
satisfied, or (ii) if the aggregate amount of the portion of the Borrowing Base
attributable thereto does not exceed the lesser of (A) $25,000,000 or (B) five
percent (5%) of the Aggregate Commitment at any time; provided that the waivers
permitted under this clause (ii) shall be limited to waivers of Borrowing Base
Sublimits and time limitations set forth in the eligibility requirements (e.g.
number of days eligible in the Aggregate Borrowing Base, number of days out on
Company Trust Receipts, etc.); and further provided that in no event shall any
Pledged Mortgage be included as Eligible Collateral while such Pledged Mortgage
is held by the Company under a Company Trust Receipt if the Company has held
such Pledged Mortgage under a Company Trust Receipt for more than 21 days.

       7.        Handling of Collateral; Settlement Account.

                 (a)      From time to time until otherwise notified in writing
by the Required Lenders, the Collateral Agent is hereby authorized to release
documentation relating to Mortgage Loans to the Company against a trust receipt
executed by the Company in the form of Exhibit 2 hereto.  The Collateral Agent
will maintain all original trust receipts in a vault, drawer or other suitable
depositary with a one hour fire rating maintained in accordance with Federal
Agency requirements and controlled solely by Collateral Agent.  The Company
hereby represents and warrants that any request by the Company for release of
Collateral under this subparagraph (a) shall be solely for the purposes of
correcting clerical or other non-substantial documentation problems in





                                      -11-
<PAGE>   12

preparation of returning such Collateral to the Collateral Agent for ultimate
sale or exchange and that the Company has requested such release in compliance
with all terms and conditions of such release set forth herein and in the
Credit Agreement, including, without limitation, Section 4.1(b)(iv) thereof.

                 (b)      Prior to the occurrence of an Event of Default, upon
delivery by the Company to the Collateral Agent of a shipping request
substantially in the form of that attached hereto as Exhibit 3, the Collateral
Agent will transmit, or cause to be transmitted, Mortgage Loans and Securities
held by it or any Approved MBS Custodian as directed by the Company as follows:

                          (1)     If the transmittal is of documentation for
         Mortgage Loans or Securities in the possession of the Collateral Agent
         or an Approved MBS Custodian in connection with the sale thereof to an
         Approved Investor, such transmittal will be under cover of a
         transmittal letter substantially in the form of that attached hereto
         as Exhibit 4 (or such other form as may be approved by the Credit
         Agent or required under any Federal Agency program pursuant to which
         the relevant Mortgage Loans or Securities are being shipped), subject
         to modification of such Exhibit 4 pursuant to Paragraph 7(g) hereof at
         the request of the Agent.

                          (2)     If the transmittal is of documentation for
         Mortgage Loans or Securities in connection with the shipment to a
         custodian or trustee in connection with the formation of a mortgage
         pool supporting a Security (any such Security secured or otherwise
         supported by any such Mortgage Loan or Security being referred to
         herein as a " Warehouse-Related Security"), such transmittal will be
         under cover of a transmittal letter substantially in the form of that
         attached hereto as Exhibit 5 (or such other form as may be approved by
         the Credit Agent or required if the Security is being issued under any
         Federal Agency program), subject to modification of such Exhibit 5
         pursuant to Paragraph 7(g) hereof at the request of the Agent, and, in
         addition, will be conditioned upon the facts that:

                                    (i)  If the Warehouse-Related Security is
                 being issued under a Federal Agency program, there has been
                 delivered for the Warehouse-Related Security such





                                      -12-
<PAGE>   13

                 form as may be required under the Federal Agency program
                 pursuant to which such Warehouse-Related Security is being
                 issued (which form shall name the Collateral Agent or an
                 Approved MBS Custodian (as defined below) as the subscriber
                 and the Person to whom the Warehouse-Related Security is to be
                 delivered);

                                   (ii)  If the Warehouse-Related Security is
                 being issued pursuant to a program other than a Federal Agency
                 program, there has been delivered to and acknowledged by the
                 trustee and collateral agent or custodian for the underlying
                 mortgage pool a letter in form acceptable to the Collateral
                 Agent;

                                  (iii)  The Person to whom such
                 Warehouse-Related Security is to be delivered upon issuance in
                 exchange for the Mortgage Loans or Securities being shipped is
                 either (a) a Person approved by the Collateral Agent and the
                 Credit Agent which has agreed to hold such Warehouse-Related
                 Security and the proceeds of any sale or other disposition
                 thereof as custodian, agent and bailee for the benefit of the
                 Secured Parties pursuant to a custodial agreement
                 substantially in the form of that attached hereto as Exhibit 6
                 (a "Custodial Agreement"), (b) the Collateral Agent or an
                 Affiliate thereof or (c) such other Person as is approved by
                 the Collateral Agent and the Credit Agent (any Person acting
                 in such capacity being referred to herein as an "Approved MBS
                 Custodian");

                                   (iv)  There has been delivered to the
                 Approved MBS Custodian a letter in the form attached to the
                 Custodial Agreement (Exhibit A to Exhibit 6 hereto); and

                                   (v)  At the request of the Agent pursuant to
                 Paragraph 7(g) hereof, any Warehouse Related Security
                 delivered to the Collateral Agent or an Approved MBS Custodian
                 pursuant to subparagraphs (i) through (iv) shall be in a face
                 amount of not less than the amount of the Aggregate Borrowing
                 Base which is attributable to the Mortgage Loans so delivered
                 in exchange for such Warehouse Related Security.





                                      -13-
<PAGE>   14

In no event shall the Collateral Agent have any obligation to obtain written
acknowledgement of receipt from the addressee of any transmittal letter or
other communication sent by the Collateral Agent hereunder.

                 (c)      All amounts payable on account of the sale of Pledged
Items (including, but not limited to, a sale pursuant to a repurchase
agreement) will be instructed to be paid directly by the purchaser to the
Settlement Account or, in the case of Pledged Securities delivered to an
Approved MBS Custodian, to a demand deposit account maintained with such
Approved MBS Custodian (a "Custodian Settlement Account") and, thereafter, to
the Settlement Account as provided in the applicable Custodial Agreement.
Pursuant to Paragraph 3 above the Company has granted a security interest in
and lien upon the Settlement Account and in all Custodian Settlement Accounts
and in any and all amounts at any time held therein as collateral security for
the benefit of the Secured Parties.  This Paragraph 7(c) shall constitute
notice to the Collateral Agent and any Approved MBS Custodian of such security
interest pursuant to the Uniform Commercial Code of all relevant jurisdictions
and any other law or regulation requiring such notice.  This Paragraph 7(c)
shall further constitute irrevocable notice to the Collateral Agent and any
Approved MBS Custodian that the accounts referred to in Paragraph 4(f) above
are "no access" accounts to the Company and the Collateral Agent except to the
extent expressly permitted hereunder.  The Collateral Agent shall hold such
security interest in and lien upon the accounts referred to in Paragraph 4(f)
above and all funds at any time held therein for the benefit of the Secured
Parties with all rights of a secured party under the Uniform Commercial Code of
all relevant jurisdictions.

                 (d)      Prior to the occurrence of an Event of Default, the
Collateral Agent and any Approved MBS Custodian shall take such steps as they
may be reasonably directed from time to time by the Company in writing which
are not inconsistent with the provisions of this Security Agreement and the
other Credit Documents and which the Company deems necessary to enable the
Company to perform and comply with Approved Investor Commitments and with other
agreements for the sale or other disposition in whole or in part of Mortgage
Loans and Securities.

                 (e)      The Collateral Agent may deliver any item of





                                      -14-
<PAGE>   15

Collateral to the Company or any other Person in accordance with the provisions
of the Credit Documents; provided, however, that the Collateral Agent shall not
deliver and shall incur no liability to the Company or any other Person for
refusing to deliver any item of Collateral to the Company or any other Person
(other than under existing Approved Investor Commitments) while an Event of
Default exists if the Collateral Agent has been directed to refrain from so
delivering Collateral by the Required Lenders.

                 (f)      In addition to the releases of Collateral provided
for in subparagraphs (a)-(e) of this Paragraph 7, upon the request of the
Company delivered from time to time to the Credit Agent and the Collateral
Agent, the Collateral Agent shall, with the prior written approval of the
Credit Agent, release Collateral specified in such notice from the lien of this
Security Agreement.  The Credit Agent shall give its approval of such release
if, but only if, (i) at the time of such release no Event of Default exists and
no notice of a Default has been issued that has not been cured, and (ii) any
payment under Section 2.14(a) of the Credit Agreement which may be required as
a result of such release has been made (or contemporaneously with such release
shall be made) so that the release of such Collateral will not create a
violation of any Lending Sublimit or Borrowing Base Sublimit, provided, however
that, while an Event of Default exists or while a notice of Default has been
issued but not cured, the Collateral Agent may (A) release pledged Cash
Equivalents which are the subject of reverse repurchase obligations in
connection with the applicable reverse repurchase agreement, and (B) release
Pledged Items in connection with the sale of Pledged Items pursuant to an
existing Approved Investor Commitment if, in either case, the proceeds of such
repurchase or sale are deposited in the Settlement Account.  The Collateral
Agent is authorized to execute and deliver to the Company, on behalf of the
Secured Parties, such UCC-3 partial release forms or other evidence as may be
required of any release permitted hereunder.

                 (g)      Notwithstanding the provisions of Paragraph 7(b)
above, at the request of the Agent:

                          (i)  The second sentence of the second full paragraph
                 of the form of whole loan sale transmittal letter attached
                 hereto as Exhibit 4 shall be deleted and replaced with the
                 following sentence:

                          interest in favor of National City Bank of Kentucky
                          (the "Collateral Agent") on behalf of the Secured
                          Parties, which security interest shall be
                          automatically released upon your remittance of an
                          amount equal to the greater of (1) the purchase price

                          remitted by wire transfer to the following account:",

                 in which case the amount to be inserted in the blank in clause
                 two of such revised provision shall be an amount equal to the
                 amount of the Borrowing Base which is attributable to the
                 Mortgage Loans being delivered pursuant to the transmittal
                 letter;

                          (ii)  The second sentence of the second full
                 paragraph of the form of warehouse related security
                 transmittal letter attached hereto as Exhibit 5 shall be
                 deleted and replaced with the following sentence:

                          interest in favor of National City Bank of Kentucky

                          Secured Parties, which security interest shall be
                          automatically released upon the issuance of the

                          enclosed herewith, which form shall name either the
                          Collateral Agent or another person designated by the
                          Collateral Agent as the person to whom the
                          Warehouse-Related Security is to be delivered and

                                      -16-
<PAGE>   17

                 amount of the Borrowing Base which is attributable to the
                 Mortgage Loans being delivered pursuant to the transmittal 
                 letter.

The Agent may require that the above described modifications be made to all
such transmittal letters or only to transmittal letters to certain Approved
Investors designated by the Agent.

       8.        Abatement of Security Interest.  Upon the occurrence of a
Positive Security Event and so long as each of the Positive Security Conditions
is satisfied and no other Negative Security Event has occurred, the security
interest granted to the Secured Parties pursuant to Paragraph 3 herein shall
abate.  The Credit Agent shall advise the Collateral Agent when such abatement
is in effect promptly after the Company notifies the Credit Agent that such a
Positive Security Event has occurred and shall advise the Collateral Agent if
such abatement expires under the terms of the Credit Agreement.  The Collateral
Agent shall, at the request of the Company and after the Credit Agent has
confirmed to the Collateral Agent that a Positive Security Event has occurred
and all Positive Security Conditions are satisfied, execute and deliver such
UCC-3 financing statements as may be required to evidence the abatement of any
security interest that shall previously have been perfected by means of the
filing of financing statements.  As a condition to such abatement, the Company
and each Borrowing Subsidiary shall execute such UCC-1 financing statements and
other documentation as the Collateral Agent may request to permit the security
interest in the Collateral to be reinstated and perfected by the Collateral
Agent without further action by the Company or any Borrowing Subsidiary if a
Negative Security Event should occur thereafter.  Although the Company and the
Borrowing Subsidiaries shall continue to deliver Mortgage Loan files and other
information and documents to the Collateral Agent (in a custodial capacity)
even while the security interest is abated, so long as the security interest is
abated the Company shall perform all of the obligations of the Collateral Agent
as set forth herein with respect to determining the Borrowing Base and
delivering Borrowing Base Reports.  During such abatement period, (i) the
remedies pertaining to the Collateral available to the Collateral Agent, the
Secured Parties and the Credit Agent under Paragraphs 16 and 17 or applicable
law shall not be available, (ii) the Company shall perform all of the
obligations of the Collateral Agent with respect to determining the Borrowing
Base, (iii) the Collateral Agent will





                                      -17-
<PAGE>   18

not be required to sell the Collateral or otherwise take any action at the
direction of the Credit Agent to realize upon the Collateral, (iv) the
Collateral Agent shall be required to sell the Collateral or otherwise take any
action with regard to the disposition of the Collateral at the direction of the
Company, and (v) the Collateral shall be deemed not to constitute security
unless and until a Negative Security Event occurs thereafter.

                 Upon the occurrence of a Negative Security Event, the Company
(with respect to Collateral owned by the Company) and each Borrowing Subsidiary
(with respect to Collateral owned by the Borrowing Subsidiaries) shall be
deemed to have (i) automatically re-pledged and re-granted to the Collateral
Agent for the benefit of the Secured Parties a first priority security interest
in the Collateral to secure payment of the Secured Debt, (ii) consented to the
Collateral Agent's filing of the UCC-1 financing statements and dating and
otherwise completing, filing and/or recording, if necessary, any other
documentation previously provided by the Company or any Borrowing Subsidiary to
the Collateral Agent, and (iii) reaffirmed its appointment of the Collateral
Agent to act as its bailee pursuant to the provisions of Section 9-305 of the
Uniform Commercial Code of any applicable state.  Upon notice from the Credit
Agent that a Negative Security Event has occurred, the Collateral Agent shall
be deemed to have been informed of and accepted such appointment and shall file
UCC-1 financing statements executed by the Company and the Borrowing
Subsidiaries and other documentation as the Collateral Agent may request to
permit the security interest in the Collateral to be reinstated.  The Company
shall pay or shall reimburse the Collateral Agent for the payment of any filing
costs incurred in connection with the filing of any UCC-1 or UCC-3 statements
pursuant to this Paragraph 8.

       9.        Reports.  The Collateral Agent shall (a) deliver the Borrowing
Base Report at the times and in the manner set forth in Paragraph 6(a) above
and (b) deliver to the Credit Agent, the Company and any Lender which makes a
written request therefor, such other reports and information as any Lender may
from time to time reasonably request.  In preparing any such reports the
Collateral Agent shall be entitled to rely, without independent investigation
(other than the review steps described on Exhibit 1 hereto), on information
supplied to the Collateral Agent by the Company.

     10.         No Reliance.  The Collateral Agent shall not be





                                      -18-
<PAGE>   19

responsible to any Secured Party for any recitals, statements, representations
or warranties contained herein or in any other Credit Document; or for the
execution, effectiveness, genuineness, validity, enforceability,
collectability, accuracy, completeness or sufficiency of this Security
Agreement or any other Credit Document or instruments executed and delivered,
or which could have been executed or delivered, in connection with this
Security Agreement or the other Credit Documents, including, without
limitation, the attachment, creation, effectiveness or perfection of the
security interests granted or purported to be granted hereunder in and to the
Collateral.

     11.         Costs and Expenses.  The Collateral Agent shall notify the
Company of all extraordinary costs and expenses of the Collateral Agent
directly relating to the Collateral Agent's performance of this Security
Agreement, and such extraordinary costs and expenses shall be paid promptly by
the Company or, if already paid by the Collateral Agent, the Company promptly
shall reimburse the Collateral Agent therefor.  For the purposes of this
provision, extraordinary costs and expenses shall include all costs and
expenses incurred by the Collateral Agent in performance of this Security
Agreement which have not been factored into the computation of the Collateral
Agent's fee (as agreed upon between the Company and the Collateral Agent
pursuant to a separate agreement), including, without limitation, reasonable
expenses of legal counsel to the Collateral Agent to enforce the rights of the
Collateral Agent hereunder.

     12.         Availability of Documents.  The Secured Parties and their
agents, accountants, attorneys and auditors (each an "Inspecting Party") will
be permitted from time to time upon reasonable notice to the Collateral Agent
and the Company, and at such time as may be mutually acceptable to such
Inspecting Party, the Collateral Agent and the Company to examine (to the
extent permitted by applicable law) the files, documents, records and other
papers in the possession or under the control of the Collateral Agent relating
to any or all Collateral and to make copies thereof.  Any such activity will be
at the cost and expense of the Secured Party requesting such access, except
that following the occurrence of an Event of Default, all reasonable
out-of-pocket costs and expenses associated with the exercise by the Credit
Agent of its rights under this Paragraph 12 shall be promptly paid by the
Company upon demand of the Credit Agent.

     13.         Representations and Warranties.  The Company, with respect to
Collateral pledged hereunder by the Company, and each Borrowing Subsidiary,
with respect to Collateral pledged hereunder by any such Borrowing Subsidiary,
hereby represents and warrants that:  (a) the Company or the Borrowing
Subsidiary, as applicable, is the sole owner of the Collateral (or, in the case
of after-acquired Collateral, at the time the Company acquires rights in the
Collateral, will be the sole owner thereof), subject only to the rights of
Approved Investors under the Approved Investor Commitments; (b) except for
security interests in favor of the Collateral Agent for the benefit of the
Secured Parties hereunder, no Person has (or, in the case of after-acquired
Collateral, at the time the Company acquires rights therein, will have) any
right, title, claim or interest in, against or to the Collateral and, in any
event, so long as the Collateral Agent complies with the procedures relating to
possession of Collateral set forth in this Security Agreement, the Collateral
Agent shall have a perfected, first priority security interest therein for the
benefit of the Secured Parties; (c) no consent of any Person is required that
has not been obtained for the granting of the security interests provided for
herein, nor will any consent be required for the Collateral Agent to exercise
its rights under this Security Agreement in accordance with the terms of this
Security Agreement (except for consents to assignments of options, futures
contracts or other interest rate protection products in favor of the Secured
Parties from the counterparties thereto, which consents shall not be required
to be obtained unless an Event of Default is continuing or the Required Lenders
request otherwise); (d) to the best of the Company's and the Borrowing
Subsidiary's knowledge, all information heretofore, herein or hereafter
supplied to the Collateral Agent or to any Lender by or on behalf of the
Company with respect to the Collateral is or will be accurate and complete; (e)
the Approved Investor Commitments covering such Collateral may be collaterally
assigned to the Collateral Agent as described herein; and (f) each Mortgage
Loan and Security is, at all dates included in the computation of the value of
the Borrowing Bases, Eligible Collateral.

     14.         Covenants of the Company and Borrowing Subsidiaries.  The
Company and the Borrowing Subsidiaries hereby agree: (a) to procure, execute
and deliver from time to time (unless a Positive Security Event has occurred
and is continuing) any endorsements, assignments, financing statements and
other writings deemed





                                      -20-
<PAGE>   21

necessary or appropriate by the Collateral Agent or the Credit Agent to
perfect, maintain and protect the Collateral Agent's security interest
hereunder and the priority thereof and to deliver promptly to the Collateral
Agent all originals of any Collateral or proceeds thereof consisting of chattel
paper or instruments; (b) not to surrender or lose possession of (other than to
the Collateral Agent), sell, encumber, or otherwise dispose of or transfer, any
Collateral or right or interest therein other than shipment of Mortgage Loans
and Securities under Approved Investor Commitments and as otherwise permitted
under Paragraph 7 above and as otherwise permitted by the Credit Agreement; (c)
except as otherwise contemplated in any Custodial Agreement, not to grant to
any Federal Agency or Approved Investor any other security interest in any
Collateral, or otherwise acknowledge the creation of any ownership rights of
any Federal Agency or Approved Investor with respect to any Collateral unless
and until the Collateral Agent has received the proceeds of such Collateral as
described herein; (d) at all times to account fully for and promptly to deliver
to the Collateral Agent, in the form received, all Collateral or proceeds
thereof received, endorsed to the Collateral Agent or in blank as appropriate
and accompanied by such assignments and powers, duly executed, as the
Collateral Agent or the Credit Agent shall request, and until so delivered all
Collateral and proceeds thereof shall be held in trust for the Collateral Agent
for the benefit of the Secured Parties, separate from all other property of the
Company and the Borrowing Subsidiaries and identified as the property of the
Collateral Agent for the benefit of the Secured Parties; (e) to keep accurate
and complete records of the Collateral and at any reasonable time and at the
Company's expense, upon demand by the Collateral Agent or the Credit Agent, to
exhibit to and allow inspection of the Collateral and the records, reports and
information concerning the Collateral by the Collateral Agent or Credit Agent
(or Persons designated by the Collateral Agent or Credit Agent); (f) to keep
the records concerning the Collateral at the location(s) set forth in Paragraph
27 below and not to remove the records from such location(s) without the prior
written consent of the Collateral Agent and the Credit Agent; (g) not to
materially modify, compromise, extend, rescind or cancel any deed of trust,
mortgage, note or other document, instrument or agreement connected with any
Mortgage Loan pledged under this Security Agreement or any document relating
thereto or connected therewith or consent to a postponement of strict
compliance on the part of any party thereto with any term or provision thereof
in any material respect; (h) to





                                      -21-
<PAGE>   22

keep the Collateral insured against loss, damage, theft, and other risks
customarily covered by insurance, and such other risks as the Collateral Agent
or the Credit Agent may request; (i) to do all acts that a prudent investor
would deem necessary or desirable to maintain, preserve and protect the
Collateral; (j) not knowingly to use or permit any Collateral to be used
unlawfully or in violation of any provision of this Security Agreement, the
Credit Agreement or any applicable statute, regulation or ordinance or any
policy of insurance covering the Collateral; (k) to pay (or require to be paid)
prior to their becoming delinquent all taxes, assessments, insurance premiums,
charges, encumbrances and liens now or hereafter imposed upon or affecting any
Collateral except as otherwise permitted in the Credit Agreement; (l) to notify
the Collateral Agent and the Credit Agent before any such change shall occur of
any change in the Company's name, identity or structure through merger,
consolidation or otherwise; (m) to appear in and defend, at the Company's cost
and expense, any action or proceeding which may affect its title to or the
Collateral Agent's interest for the benefit of the Secured Parties in the
Collateral; and (n) to comply in all material respects with all laws,
regulations and ordinances relating to the possession, operation, maintenance
and control of the Collateral.  Notwithstanding the foregoing, (1) the
requirements of clauses (g), (k) and (m) shall not apply to any Collateral
which is not required to be included in the computation of the value of any of
the Borrowing Base in order for the Company to be in compliance with the
requirements of the Credit Agreement unless failure to comply with the
requirements of said subparagraphs would have an adverse effect on the
Collateral which is included in such computation, and (2) the failure of the
Company or any Borrowing Subsidiary to comply with its obligations under this
Paragraph 14 with respect to any Pledged Item shall cause such Pledged Item to
cease to qualify as Eligible Collateral.

     15.         Collection of Collateral Payments.

                 (a)      The Company or the applicable Borrowing Subsidiary
shall, at its sole cost and expense, use its best efforts to obtain payment,
when due and payable, of all sums due or to become due with respect to any
Collateral ("Collateral Payments" or a "Collateral Payment"), consistent with
all requirements of law and contractual obligations binding upon the Company or
the applicable Borrowing Subsidiary.  Upon the request of the Collateral Agent
while an Event of Default exists, the Company or the applicable





                                      -22-
<PAGE>   23

Borrowing Subsidiary will notify and direct any party who is or might become
obligated to make any Collateral Payment, to make payment thereof to the
Collateral Agent (or to the Company or the applicable Borrowing Subsidiary in
care of the Collateral Agent) at such address as the Collateral Agent may
designate.  The Company will reimburse the Collateral Agent promptly upon
demand for all out-of-pocket costs and expenses, including reasonable
attorneys' fees and litigation expenses, incurred by the Collateral Agent in
seeking to collect any Collateral Payment.

                 (b)      The Collateral Agent shall, promptly upon receipt of
any funds delivered from any Servicing Purchaser as full or partial payment of
any Pledged Servicing Sale Receivable, deposit such funds into the Collateral
Agent's Settlement Account and notify the Company of the receipt of such funds.
If the Collateral Agent receives any check from a Servicing Purchaser in
payment of Servicing Sale Receivables and such check contains a restrictive
endorsement, the Collateral Agent shall obtain the consent of the Company and
the Credit Agent before cashing any such check.

                 (c)      Following the occurrence of an Event of Default, upon
the request of the Collateral Agent the Company and each Borrowing Subsidiary
will transmit and deliver to the Collateral Agent, forthwith upon receipt and
in the form received, all cash, checks, drafts and other instruments for the
payment of money (properly endorsed where required so that such items may be
collected by the Collateral Agent) which may be received by the Company or any
Borrowing Subsidiary at any time as payment on account of any Collateral
Payment and if such request shall be made, until delivery to the Collateral
Agent, such items will be held in trust for the Collateral Agent for the
benefit of the Secured Parties and will not be commingled by the Company or any
Borrowing Subsidiary with any of their other funds or property.  Thereafter,
the Collateral Agent is hereby authorized and empowered to endorse the name of
the Company or the applicable Borrowing Subsidiary on any check, draft or other
instrument for the payment of money received by the Collateral Agent on account
of any Collateral Payment if the Collateral Agent believes such endorsement is
necessary or desirable for purposes of collection.

                 (d)      The Company hereby agrees to indemnify, defend and
save harmless the Collateral Agent and its agents, officers, employees and
representatives from and against all reasonable





                                      -23-
<PAGE>   24

liabilities and expenses on account of any adverse claim asserted against the
Collateral Agent relating to any moneys received by the Collateral Agent on
account of any Collateral Payment (other than as a direct result of the gross
negligence or willful misconduct of the Collateral Agent) and such obligation
of the Company shall continue in effect after and notwithstanding the discharge
of the Credit Indebtedness and/or the release of the security interest granted
in Paragraph 3 above.

     16.         Authorized Action by Collateral Agent.  The Company and each
Borrowing Subsidiary each hereby irrevocably appoints the Collateral Agent as
its attorney-in-fact to do (but the Collateral Agent shall not be obligated to
and shall incur no liability to the Company, any Borrowing Subsidiary or any
Secured Party or any other third party for failure so to do) at any time and
from time to time at the written request and direction, given while an Event of
Default exists, of the Required Lenders, any act which the Company or any
Borrowing Subsidiary is obligated by this Security Agreement to do, and to
exercise such rights and powers as the Company or any Borrowing Subsidiary
might exercise with respect to the Collateral, including, without limitation,
the right to (a) collect by legal proceedings or otherwise and endorse, receive
and receipt for all dividends, interest, payments, proceeds and other sums and
property now or hereafter payable on or on account of the Collateral; (b)
insure, process, service and preserve the Collateral; (c) transfer the
Collateral to the Collateral Agent's own or its nominee's name; and (d) make
any compromise or settlement, and take any other action it deems advisable with
respect to the Collateral.  Notwithstanding the preceding sentence, the
Collateral Agent shall endeavor to take only such actions with respect to the
Collateral as are consistent with general servicing of such Collateral and in
compliance with Federal Agency requirements; provided, however, that the
Collateral Agent shall not be liable to the Company or any Borrowing Subsidiary
for any actions taken by the Collateral Agent absent gross negligence or
willful misconduct.  Notwithstanding anything contained herein, in no event
shall the Collateral Agent be required to make any presentment, demand or
protest, or give any notice, and the Collateral Agent need not take any action
to preserve any rights against any prior party or any other person in
connection with the Secured Debt or with respect to the Collateral.

     17.         Default and Remedies.

                 (a)      While an Event of Default exists under any Credit
Document, the Collateral Agent shall at the written request and direction of
the Required Lenders, without notice to or demand upon the Company:  (a)
foreclose or otherwise enforce the Collateral Agent's security interest for the
benefit of the Secured Parties in the Collateral in any manner permitted by law
or provided for hereunder; (b) sell or otherwise dispose of the Collateral or
any part thereof at one or more public or private sales or at any broker's
board or on any securities exchange, whether or not such Collateral is present
at the place of sale, for cash or credit or future delivery and without
assumption of any credit risk, on such terms and in such manner as the
Collateral Agent may determine; (c) require the Company to assemble the
Collateral and/or books and records relating thereto and make such available to
the Collateral Agent at a place to be designated by the Collateral Agent; (d)
enter into property where any Collateral or books and records relating thereto
are located and take possession thereof with or without judicial process; and
(e) prior to the disposition of the Collateral, prepare it for disposition in
any manner and to the extent the Collateral Agent deems appropriate.  Whether
or not the Collateral Agent exercises any right given pursuant to this
Paragraph 17, upon the occurrence of any Event of Default, the Collateral Agent
on behalf of the Secured Parties shall have as to any Collateral all other
rights and remedies provided for herein and all rights and remedies of a
secured party under the Illinois Uniform Commercial Code and, in addition
thereto and not in lieu thereof, all other rights or remedies at law or in
equity existing or conferred upon the Collateral Agent on behalf of the Secured
Parties by other jurisdictions or other applicable law or given to the
Collateral Agent on behalf of the Secured Parties pursuant to any security
agreement, other instrument or agreement heretofore, now, or hereafter given as
security for the Company's obligations hereunder.

                 (b)      The Collateral Agent is authorized, at any such sale,
if it deems it advisable so to do, to restrict the prospective bidders or
purchasers to Persons who will represent and agree that they are purchasing for
their own account, for investment, and not with a view to the distribution or
sale of any of the Collateral.  Upon any sale or other disposition pursuant to
this Security Agreement, the Collateral Agent shall have the right





                                      -25-
<PAGE>   26

to deliver, assign and transfer to the purchaser thereof the Collateral or
portion thereof so sold or disposed of and all proceeds thereof shall be
promptly distributed as set forth in Paragraph 18 hereof.  Each purchaser at
any such sale or other disposition shall hold the Collateral free from any
claim or right of whatever kind, including any equity or right of redemption of
the Company or any Borrowing Subsidiary, and the Company and the Borrowing
Subsidiaries specifically waive (to the extent permitted by law) all rights of
redemption, stay or appraisal which they have or may have under any rule of law
or statute now existing or hereafter adopted.  The Collateral Agent shall give
the Company or the applicable Borrowing Subsidiary only such notice and shall
publish such notice as may be required by the Illinois Uniform Commercial Code
or the Kentucky Commercial Code or by other applicable law of the intention to
make any such public or private sale or sale at broker's board or on a
securities exchange.  Any such public sale shall be held at such time or times
within the ordinary business hours and at such place or places permitted by the
Illinois Uniform Commercial Code or the Kentucky Commercial Code.  At any such
sale the Collateral may be sold in one lot as an entirety or in separate
parcels, as the Collateral Agent may determine.  The Collateral Agent may
adjourn any public or private sale or cause the same to be adjourned from time
to time by announcement at the time and place fixed for the sale, and such sale
may be made at any time or place to which the same may be so adjourned.  In
case of any sale of all or any part of the Collateral on credit or for future
delivery, (i) the Collateral so sold may be retained by the Collateral Agent
until the selling price is paid by the purchaser thereof, (ii) none of the
Secured Parties shall incur any liability in case of the failure of such
purchaser to take up and pay for the Collateral so sold, and (iii) in case of
any such failure, such Collateral may again be sold as provided herein.
Nothing contained in this Security Agreement shall prohibit any Lender or
Lenders from purchasing the Collateral at such sale.

     18.         Disposition of Proceeds.

                 "Net Proceeds" shall mean the proceeds realized upon the sale
or other disposition of any Collateral after deducting therefrom the payment of
the costs and expenses of such sale or disposition, including reasonable
compensation to the Collateral Agent's and Credit Agent's agents and counsel,
and all expenses,





                                      -26-
<PAGE>   27

liabilities and advances made or incurred by any Secured Party acting on
instructions of the Required Lenders.  All such costs and expenses shall be
deducted from the proceeds directly related thereto or, in the absence of any
such direct relationship, on a pro rata basis from all types of proceeds
recovered by the Collateral Agent.  The total of all Net Proceeds for all
categories of Collateral is referred to as "Aggregate Net Proceeds."  To the
extent the Credit Agent is holding any Net Proceeds (e.g. amounts held in the
Settlement Account), the Credit Agent shall notify the Collateral Agent of the
amount of such Net Proceeds in order to enable the Collateral Agent to
calculate the Aggregate Net Proceeds.  The Collateral Agent shall distribute to
the Credit Agent for the benefit of the Lenders an amount equal to the
Aggregate Net Proceeds held by the Collateral Agent.  The Credit Agent shall
notify the Collateral Agent in writing of the manner in which Aggregate Net
Proceeds shall be delivered to the Credit Agent (e.g. by providing wire
transfer instructions).

     19.         Waiver.  No Secured Party shall incur any liability as a
result of the sale of the Collateral, or any part thereof, at any public or
private sale.  The Company and each Borrowing Subsidiary each hereby waives any
claims it may have against any Secured Party arising by reason of the fact that
the price at which the Collateral may have been sold at such private sale was
less than the price which might have been obtained at a public sale or was less
than the aggregate amount of the Secured Debt then outstanding.

     20.         The Collateral Agent

                 (a)      Collateral Agent's Fee.  Compensation of the
Collateral Agent for its services hereunder and reimbursement for any expenses
incurred by it in the performance of its duties hereunder shall be paid by the
Company pursuant to a separate written agreement between the Collateral Agent
and the Company.

                 (b)      Actions by the Collateral Agent.  The obligations of
the Collateral Agent hereunder are only those expressly set forth herein.  The
Collateral Agent shall be entitled to (but shall not be obligated to) take or
refrain from taking any discretionary powers or actions under this Security
Agreement or any other Credit Document unless and until the Collateral Agent
shall have received the written direction to take or refrain from taking such
action





                                      -27-
<PAGE>   28

from the Required Lenders.  The Collateral Agent shall not be required to take
any action hereunder if it shall reasonably determine that by so doing it may
incur criminal or civil liability.

                 (c)      Consultation with Experts.  The Collateral Agent may
consult with legal counsel (who may be counsel for the Company), independent
public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken by it in good faith in accordance with
the advice of such counsel, accountants or experts.

                 (d)      Liability of Collateral Agent.

                 (1)      Neither the Collateral Agent nor any of its
         directors, officers, agents, or employees shall be liable for any
         action taken or not taken by it in connection herewith (i) with the
         consent or at the request of the Required Lenders or (ii) in the
         absence of its own gross negligence or willful misconduct.

                 (2)      The Collateral Agent shall not incur any liability by
         acting in reliance upon any notice, consent, certificate, statement,
         or other writing (which may be a bank wire, telex or similar writing)
         or telephone communication believed by it to be genuine or, in the
         case of a writing, to be signed by the proper party or parties.

                 (e)      Indemnification.  Subject to the limitations set
forth below, the Lenders shall indemnify the Collateral Agent (to the extent
not reimbursed by the Company) against any cost, expense (including reasonable
counsel fees and disbursements), claim, demand, action, loss or liability
(except such as result from the Collateral Agent's gross negligence or willful
misconduct) that the Collateral Agent may suffer or incur in connection with
this Security Agreement or any action taken or omitted by the Collateral Agent
hereunder (the "Indemnified Amount").  Any Indemnified Amount due to the
Collateral Agent shall be paid by the Lenders pro rata in accordance with their
respective Commitment Percentages.

                 (f)      Knowledge of Defaults.  The Collateral Agent shall
not be deemed to have knowledge or notice of the occurrence of any Event of
Default unless the Collateral Agent has received notice





                                      -28-
<PAGE>   29

from a Secured Party or the Company referring to the Credit Agreement, this
Security Agreement describing such Event of Default and stating that such
notice is a "Notice of Default."  Following receipt of a Notice of Default, the
Collateral Agent shall assume that the Event of Default is continuing until the
Collateral Agent receives written information to the contrary from the Credit
Agent.

                 (g)      Reports.  The Collateral Agent may, at its option
with the approval of the Company and the Credit Agent, alter the format of any
report required hereunder, provided such modified report contains the same
information previously furnished in the unmodified report.

                 (h)      Other Transactions with Company.  The Collateral
Agent and its Affiliates may accept deposits from, lend money to, and generally
engage in any kind of business with, the Company or any Subsidiary or Affiliate
of the Company as if it were not the Collateral Agent hereunder.

                 (i)      Resignation/Removal.  The Collateral Agent may resign
at any time by giving 90 days prior written notice thereof to the Credit Agent
and the Company.  The Collateral Agent agrees to resign within 60 days after
written notice by the Company requesting the resignation of the Collateral
Agent provided that no Event of Default has occurred and is continuing at the
time of such request.  In addition, in the event the Collateral Agent fails to
perform its obligations under this Security Agreement in any material manner
and fails to correct its performance within 30 days of receipt of written
notice of such failure given by the Credit Agent at the request of not less
than the Required Lenders, then the Collateral Agent may be removed upon 30
days written notice given by the Credit Agent at the direction of not less than
the Required Lenders.  Upon any such resignation or removal:  (i) so long as
there has not occurred and is continuing an Event of Default, the Company shall
appoint from among the Lenders (which appointment shall be subject to the
approval of the Required Lenders, such approval not to be unreasonably withheld
or delayed), a successor agent for such Collateral Agent, and (ii) following
the occurrence and during the continuance of an Event of Default, the Required
Lenders shall appoint from among the Lenders, a successor agent for such
Collateral Agent.  Following the appointment and acceptance of a successor
Collateral Agent the Credit Agent shall notify the Collateral Agent as to who
the successor Collateral





                                      -29-
<PAGE>   30

Agent is and the Collateral shall be transferred to the new Collateral Agent
within 30 days after such acceptance.  If the Company and/or the Required
Lenders, as applicable, are unable to agree on the appointment of a successor
agent prior to the expiration of any of the time periods set forth above, the
Credit Agent (or an Affiliate thereof designated by the Credit Agent) shall be
deemed a successor Collateral Agent until the appointment of and acceptance by
a different successor Collateral Agent, and the Collateral Agent shall be
permitted to transfer all the Collateral held by the Collateral Agent to the
Credit Agent (or an Affiliate thereof designated by the Credit Agent) within 30
days after the of the applicable time period set forth above.  Within 30 days
after the appointment of a successor Collateral Agent and the successor's
acceptance of such appointment, that successor Collateral Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Collateral Agent, and the retiring Collateral Agent shall be
discharged from its duties and obligations under this Security Agreement;
provided, however, that the retiring Collateral Agent shall not be discharged
from any liability as a result of its or its directors', officers', agents' or
employees' gross negligence or willful misconduct in connection with the
performance of its duties and obligations under this Security Agreement prior
to the effective date of its resignation or removal.  Notwithstanding the
foregoing, the Collateral Agent shall continue to hold the Pledged Items and
the security interest created hereunder for the benefit of the Secured Parties
until such Pledged Items and security interest have been effectively
transferred to the successor agent.  After the resignation or removal of any
Collateral Agent hereunder, the provisions of this Security Agreement shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was the Collateral Agent under this Security Agreement.

                 (j)      Representations and Warranties.  The Collateral Agent
hereby represents and warrants:

                 (1)      The Collateral Agent is a national banking
                 association validly existing, in good standing and authorized
                 to exercise its powers, rights and privileges and is qualified
                 to do business in all jurisdictions where necessary, and has
                 all requisite power and authority to perform all of its
                 obligations under this Security Agreement;

                 required hereby to be executed by the Collateral Agent have
                 been duly authorized by all necessary corporate action and do
                 not and will not violate any existing provision of any law,

                 determination or award currently in effect having
                 applicability to the Collateral Agent; and

confidentiality of all non-public information provided to it by the Company or
any Borrowing Subsidiary or by any other party on the Company's behalf in

advisors, (7) if such information has become public other than through
disclosure by the Collateral Agent or any of its Affiliates or any Lender, and
(8) in connection with any litigation involving the Collateral Agent or any of
its Affiliates.  Notwithstanding the foregoing, the Company authorizes the
Collateral Agent to disclose to any lending institution proposed by the Company
to become a Lender under the Credit Agreement or any prospective or actual
Participants such financial and other information in its possession (i) which

require unanimous approval of the Lenders).

     23.         Binding Upon Successors.  All rights of the Collateral Agent
and the Secured Parties under this Security Agreement shall inure to the
benefit of the Collateral Agent and the Secured Parties and their successors
and assigns, and all obligations of the Company and the Borrowing Subsidiaries

obligations under this Security Agreement without the consent of all the
Lenders.

contains the entire security agreement and collateral agency agreement with
respect to the Collateral among Secured Parties, the Company and the Borrowing
Subsidiaries and supersedes all prior written or oral agreements and

Subsidiary provided for in this Security Agreement have been specifically
negotiated by the parties with full cognizance and understanding of their
rights.  If any of the provisions of this Security Agreement shall be held

                            REQUIRED REVIEW STEPS


       1.      All submitted documents, are consistent with the related
               Collateral Transmittal as to borrower name, loan face amount,
               loan type and the Company's or Borrowing Subsidiary's loan
               number.

       2.      The note and mortgage/deed of trust each bears an original
               signature or signatures which appear to be those of the person
               or persons named as the maker and mortgagor/trustor, or, in the
               case of a certified copy of the mortgage/deed of trust, such
               copy bears what appears to be a reproduction of such signature
               or signatures.

       3.      Except for (a) the endorsement to the Company or applicable
               Borrowing Subsidiary of the note in the event such loan was
               purchased by the Company or a Borrowing Subsidiary and (b) the
               endorsement in blank of the note by an authorized signatory of
               the Company or the applicable Borrowing Subsidiary, neither the
               note, the mortgage/deed of trust, nor the assignment(s) of the
               mortgage/deed of trust contain any irregular writings which
               appear on their face to affect the validity of any such
               endorsement or to restrict the enforceability of the document on
               which they appear.

       4.      The note is endorsed in blank by an authorized signatory of the
               Company or the applicable Borrowing Subsidiary.

       5.      The assignment of the mortgage/deed of trust bears an original
               signature of an authorized signatory of the Company or the
               applicable Borrowing Subsidiary.

       6.      Such other review steps as the Collateral Agent, in its sole
               discretion, deems appropriate.

       Re:     Source One Mortgage Services Corporation

Ladies and Gentlemen:

       The undersigned, National City Bank of Kentucky (the "Collateral Agent")
acts in the capacity as Collateral Agent pursuant to:  (1) that certain Third
Amended and Restated Revolving Credit Agreement dated as of July __, 1997 (as
amended from time to time, the "Credit Agreement", and as capitalized terms not
otherwise defined herein are used with the same meaning as in the Credit
Agreement) by and among SOURCE ONE MORTGAGE SERVICES CORPORATION (the
"Company"), THE MORTGAGE AUTHORITY, ("TMA"), CENTRAL PACIFIC MORTGAGE COMPANY
("CPM"), the lenders participating therein (collectively, the "Lenders"), and
the FIRST NATIONAL BANK OF CHICAGO, as agent for the Lenders (the "Credit
Agent"), and (2) that certain Second Amended and Restated Security and
Collateral Agency Agreement (as amended from time to time, the "Security
Agreement") dated concurrently therewith among the Collateral Agent, the
Company, TMA, CPM and the Credit Agent.  TMA and CPM are each referred to
herein as a "Borrowing Subsidiary".

       The Collateral Agent represents and confirms that it has the power and
authority under the Credit Agreement and the Security Agreement to execute this
Custodial Agreement.  The Collateral Agent may execute any of its duties
hereunder by or through agents or attorneys-in-fact of whose appointment you
have been notified in writing.

       The Collateral Agent hereby appoints you and you hereby accept
appointment to act as agent, custodian and bailee for the benefit of the
Secured Parties (as defined in the Security Agreement) (in such capacity, the
"Approved MBS Custodian").  In such capacity, you agree to accept delivery only
on a free basis of certain mortgage-backed securities delivered to you from
time to time identified in a letter in the form attached hereto as Exhibit A
(all such mortgage-backed securities delivered to you and so 





                                      -54-
<PAGE>   55

identified being referred to herein as "Subject Securities").  This Custodial
Agreement governs your rights and responsibilities as Approved MBS Custodian
with respect to all Subject Securities.

       From time to time the security interest of the Collateral Agent may be
abated upon a "Positive Security Event" under the terms of the Credit Agreement
and the Security Agreement.  The Collateral Agent will promptly advise you of
any such abatement and issue directions to you regarding the effect of such
event on your duties and obligations hereunder.

       The Collateral Agent hereby directs you, as Approved MBS Custodian, to
hold or dispose of Subject Securities deposited with you only in accordance
with the instructions of a person described as an "Authorized Collateral Agent
Representative" on a schedule from time to time delivered to you by the
Collateral Agent (the initial list of such persons being attached hereto as
Schedule I) or otherwise as expressly permitted hereunder, including without
limitation the Company's or any Borrowing Subsidiary's right to direct the sale
or disposition of the Subject Securities as described in the following
paragraph.  You are authorized, directed and instructed to act upon all
instructions from persons reasonably believed by you to be genuine and
authorized.  Any instruction given hereunder may, in your discretion, be by
telegraph, cable, facsimile or electronic communication which is received by
you.

       All Subject Securities are to be held by you in a custodial account
(Account No. __________) maintained with you (the "MBS Custodial Account").
Unless and until you have received written notice to the contrary from the
Collateral Agent at the direction of the Required Lenders (which notice may be
by facsimile transmission) following an Event of Default, you may from time to
time deliver Subject Securities at the direction of the Company, to, but only
to, Approved Investors (as listed on a schedule of "Approved Investors"
delivered to you from time to time by an Authorized Collateral Agent
Representative) against payment of the purchase price therefor.
Notwithstanding the preceding sentence, even after your receipt of notice from
the Collateral Agent that an Event of Default exists, you may deliver Subject
Securities at the direction of the Company, but only to Approved Investors
pursuant to then-existing Approved Investor Commitments.  The proceeds of the
sale or other disposition of all Subject Securities are to be held by you in an
account (Account No. __________) maintained with you (the "Custodian Settlement
Account") and transferred by the end of each Business Day to Account No.
19-19210 maintained in the Credit Agent's name at The First National Bank of
Chicago (the "Settlement Account") as follows:

                         ______________________________
                         ______________________________
                         ______________________________






                                      -55-
<PAGE>   56

       By executing this Custodial Agreement the Company and the Borrowing
Subsidiaries confirm and the Collateral Agent, the Company and the Borrowing
Subsidiaries notify you that the Company and the Borrowing Subsidiaries have
assigned and granted to the Collateral Agent a security interest in and lien
upon all now existing and hereafter arising right, title and interest
of the Company and the Borrowing Subsidiaries in the MBS Custodial Account, the
Custodian Settlement Account and the Settlement Account and in any and all
investments and proceeds at any time held therein.

       Unless and until you have received written notice from an Authorized
Collateral Agent Representative (which notice may be by facsimile transmission)
that there has occurred an Event of Default or Default, you may, at your
election, elect to make advances against Subject Securities held by you in the
MBS Custodial Account pending their sale and delivery to a purchaser thereof,
in accordance with a repo line of credit established between you and the
Company; provided, however, that:  (1) any such repo line of credit shall be on
terms and conditions customary for similar lines of credit which you provide to
customers, including, without limitation, as to advance rate and interest
charge; (2) all advances to the Company under such repo line of credit (each, a
"Repo Advance") shall be transferred to the Custodian Settlement Account; and
(3) you hereby waive any and all rights of offset, counterclaim or other
recoupment rights which you may have with respect to any Repo Advance against
the MBS Custodial Account, the Custodian Settlement Account and any Subject
Securities or proceeds thereof at any time held therein (other than the Subject
Securities which are the subject of the Repo Advance).  If, but only if and
only to the extent there has been transferred to the Custodian Settlement
Account the proceeds of a given Repo Advance, the rights of the Collateral
Agent in the Subject Securities which are the subject of the Repo Advance are
hereby automatically subordinated to your rights therein as collateral security
for the repayment of such Repo Advance, and upon receipt of such proceeds in
the Settlement Account, such rights of the Collateral Agent shall be
automatically released.

       You shall be under no duty to take or omit to take any action with
respect to Subject Securities, except as specifically set forth in this
Agreement and the Operating Instructions attached hereto as Exhibit B, unless
specifically otherwise directed by the Collateral Agent and agreed to by you in
writing.  In the event that you shall be uncertain as to your duties or rights
hereunder, you shall be entitled to refrain from taking any action until you
shall be directed otherwise by an order of a court of competent jurisdiction.
In case you should agree to our request and on our behalf to appear in,
prosecute or defend any legal or equitable proceeding either in your own name
or in the name of your nominee, you shall first be indemnified to your
satisfaction (other than 






                                      -56-
<PAGE>   57

against your gross negligence and willful misconduct).

       By accepting delivery of any Subject Security, you shall be deemed to
have agreed to hold such Subject Security as Approved MBS Custodian hereunder,  
free and clear of all liens, claims, interests and rights of offset in your
favor or in favor of persons claiming through you, subject only to the rights
with respect to Repo Advances described above.  Until you have been notified in
writing (including by telecopier) by an Authorized Collateral Agent
Representative of the occurrence of an Event of Default, you are hereby
authorized to return Subject Securities to the issuer/transfer agent therefor at
the Company's written request in connection with the reissuance thereof in
smaller denominations; provided, however, that any delivery of Subject
Securities for reissuance shall be covered by a transmittal letter or other
written agreement instructing that the reissued securities be returned directly
to you.  In this connection, we acknowledge familiarity with the current
securities industry practice of delivering physical securities against later
payment on the delivery date. Notwithstanding our instructions to deliver
Subject Securities against payment, you are authorized to make delivery of such
physical securities against a temporary receipt (sometimes called a "window
ticket") in lieu of payment.  You agree to use your best efforts to obtain
payment therefor during the same business day, but we confirm our assumption of
all risks of payment for such deliveries.  You may accept certified checks in
payment for Subject Securities delivered on the Company's instruction and you
shall not be responsible for the risks of collectability of any such checks. 
YOU ARE HEREBY IRREVOCABLY INSTRUCTED BY THE COMPANY, EACH BORROWING SUBSIDIARY
AND THE COLLATERAL AGENT THAT ALL PROCEEDS RECEIVED FROM THE SALE OR OTHER
DISPOSITION OF SUBJECT SECURITIES AND ALL REPO ADVANCES, UNTIL OTHERWISE
NOTIFIED IN WRITING BY THE COLLATERAL AGENT, SHALL BE WIRED TO THE SETTLEMENT
ACCOUNT AS PROVIDED ABOVE.

       You will provide to the Collateral Agent on a daily basis at or before
9:30 a.m. (Chicago time) a report of the prior day's activity with respect to
the MBS Custodial Account, the Custodian Settlement Account and Repo Advances
made by you hereunder.

       You shall not be liable or accountable for any act or omission of
brokers, dealers or agents in connection with this Custodial Agreement.  In
carrying out your duties hereunder, you may use such methods or agencies as you
determine in your sole discretion, including your own facilities.

       You shall maintain regular business records documenting all instructions
transmitted to you through any authorized means and any response by you.  You
are authorized to electronically record any telephone communications with the
Company, any Borrowing Subsidiary or the Collateral Agent arising out of this
Custodial 






                                      -57-

Agreement.  Your records shall be determinative of the form, content
and time of all the Company's, the Borrowing Subsidiaries' and Collateral
Agent's instructions and any response from you.  The record of each instruction
and any response thereto shall be retained by you for at least ninety (90) days
following the date of the instruction.  Any claim against you for failure to
properly follow an instruction transmitted by the Company, any Borrowing
Subsidiary or the Collateral Agent must be made in writing and received by you
within sixty (60) days after the date such instruction was received by you.

       You shall give the Subject Securities that come into your possession
under this Custodial Agreement the same physical care and safeguards as are
afforded similar property owned by you; provided, however, your responsibility
hereunder is limited to losses occasioned directly by the gross negligence or
willful misconduct of your employees, to the extent of the market value of the
Subject Securities at the date of the discovery of such loss.  With respect to
any Subject Securities which you deliver for us to a third party, and with
respect to such delivery, you shall be deemed no more than an "intermediary" as
referenced in Section 8-306(3) of the New York Uniform Commercial Code, and the
only warranty given by you shall be the warranty provided in said Section
8-306(3).  In no event shall you be liable for any indirect, special or
consequential loss, even if you have been advised of the possibility of such
loss.  You may, at your option, make arrangements for insuring yourselves
against loss from any cause, but you shall not be under any obligation to insure
for our benefit.

       Except as expressly set forth above with respect to advances made by you
in connection with "late deliveries" and Repo Advances, none of the Subject
Securities held in the MBS Custodial Account, the funds held at any time in the
Custodian Settlement Account, the Subject Securities or any proceeds of the
sale or other disposition thereof will be subject to any right, charge,
security interest, lien, encumbrance or claim of any kind in your or your
creditors' favor.  Any claims for the payment of fees with respect to the safe
custody or administration of Subject Securities or for compensation, expenses,
commitments made by you upon instructions of the Collateral Agent,
reimbursement of taxes incurred by you for the account of the Collateral Agent,
any penalties incurred by or levied or assessed against you resulting from the
Collateral Agent's improper or incorrect instructions, or other liabilities of
the Collateral Agent to you, and for indemnity against any claim or liability
to which you are subjected by reason of any registration of Subject Securities
shall be enforceable solely against the Company and none of the Collateral
Agent, the Credit Agent or any Secured Party shall have any responsibility
therefor (except to the extent any of the foregoing are due to the gross
negligence or willful misconduct of the Collateral Agent, the Credit Agent or
any 






                                      -58-

Secured Party, as applicable).  The Collateral Agent, the Borrowing
Subsidiaries and the Company agree to make no claim against you except for any
such claims or liabilities arising, or claimed to have arisen, as a result of
your gross negligence or willful misconduct.

       The Operating Instructions attached hereto are hereby made part hereof
and any and all capitalized terms defined herein shall have the same meaning
when used therein.

       This Custodial Agreement contains the whole of the understanding between
you and the Collateral Agent concerning the subject matter hereof and no
provision hereof shall be modified or altered except in a writing signed by
both you and the Collateral Agent.

       This Custodial Agreement shall be governed by the laws of the State of
New York and shall be binding upon the Collateral Agent and upon its successors
and assigns and shall inure to your benefit and your successors and assigns and
shall be deemed continuing until terminated by either the Collateral Agent or
you upon at least sixty (60) days prior written notice to the other.

       This letter is made in triplicate and will become an agreement between
you and the Collateral Agent upon your acceptance hereof in the space provided
below at your offices in the State of New York.

on the Approved MBS Custodian's part constituting gross negligence or willful
misconduct, or (ii) any claim that is based on the Approved MBS Custodian's
warranty as provided in Section 8-306(3) of the New York Uniform Commercial

                            OPERATING INSTRUCTIONS


       These Operating Instructions are attached to and made a part of the
Custodial Agreement between National City Bank of Kentucky and
___________________, dated as of _______________, 199_ (as amended from time to
time, the "Custodial Agreement").  Terms defined therein shall have their same
meanings when used herein.

      1.       From time to time GNMA, FNMA and FHLMC Subject Securities will
be issued at the request of the Company or a Borrowing Subsidiary and credited
to your account with the Federal Reserve Bank of New York ("FRBNY") (in the
case of FNMA and FHLMC Subject Securities) or your account with the
Participants Trust Company ("PTC") (in the case of GNMA Subject Securities) (in
each case, to be held by you for the account of the Collateral Agent) in
accordance with the Code of Federal Regulations (in the case of FNMA and FHLMC
Subject Securities) or the rules of PTC (in the case of GNMA Subject
Securities).  Upon your receipt of confirmation that such Subject Securities
have been deposited into your account with FRBNY (in the case of FNMA and FHLMC
Subject Securities) or your account with PTC (in the case of GNMA Subject
Securities), you shall promptly issue to the Collateral Agent and the Company
your confirmation that (1) you have received such confirmation of the Fedwire
(in the case of FNMA and FHLMC Subject Securities, which confirmation will
include the number of Subject Securities deposited into your account with
FRBNY) or from PTC (in the case of GNMA Subject Securities), (2) you have made
appropriate entries on your books reflecting the interests of the Company or
the applicable Borrowing Subsidiary as beneficial owner and the Collateral
Agent as secured party with respect to such Subject Securities, and (3) there
are no security interests or any rights or claims of any third party in such
Subject Securities in your favor or known to you which have priority over the
security interest of the Collateral Agent in such Subject Securities.  You
shall be under no obligation to ensure or verify that Securities identified in
transmittal letters (in the form of Exhibit A to the Custodial Agreement) are
in fact credited to your account(s), but you shall be obligated only to report
your actual receipt of Subject Securities to the Collateral Agent and the
Company in accordance with the provision of this Instruction 1.

      2.       With respect to the delivery or transfer of Subject Securities
which you hold for the account of the Collateral Agent, you are hereby
authorized to act only upon instructions from the Collateral Agent or, to the
extent permitted by the Custodial Agreement, by the Company.  Upon notification
to you by the 






                                      -63-
<PAGE>   64

Collateral Agent at the direction of the Required Lenders following an "Event 
of Default" under the Credit Agreement, no third party, including without
limitation the Company and the Borrowing Subsidiaries, may direct you to make
any delivery or transfer of such Subject Securities other than Subject
Securities to be delivered pursuant to then-existing Approved Investor
Commitments.

      3.       The proceeds of redemptions, collections and other receipts,
including dividend and interest income, shall be credited to the Custodial
Settlement Account upon collection or payment.

      4.       You are to notify the Collateral Agent and the Company upon
receipt of notice by you of any call for conversion, redemption, subscription
rights or similar proceeding affecting the Subject Securities held in the
relevant account (any of the foregoing being referred to herein as "Account
Proceedings"), and shall take such action in respect thereof as you may be
directed in writing by the Collateral Agent; provided, however, that you shall
have no duty or responsibility to notify the Company or the Collateral Agent of
any Account Proceedings which do not appear in The Wall Street Journal (New
York Edition), The Standard & Poor's Called Bond Record for Preferred Stocks,
Financial Daily Called Bond Service, The Kenney Services or official
notifications from the Depository Trust Company or such other publications
which you may deem reasonable from time to time.  All solicitation fees payable
to you as agent in connection with such event will be retained by you unless
specifically agreed to the contrary by you.

      5.       You are authorized and empowered in the name and on behalf of
the Collateral Agent and the Company to execute any certificates of ownership
or other reports which you are or may hereafter be required to execute and
furnish under any regulation of the Internal Revenue Service, or other
authority of the United States, insofar as the same are required in connection
with any property which is now or may hereafter be in your possession by virtue
of the Custodial Agreement and these Operating Instructions, claiming no
exemptions on behalf of the Collateral Agent or the Company.  In the
preparation of such reports, the status of the Collateral Agent is to be
described as a bank, trust company or financial institution, as the case may
be, domiciled in the United States.  The Collateral Agent agrees to notify you
immediately in writing of any change in such status.

      6.       All mail communications which are to be furnished or forwarded
hereunder to the Collateral Agent or the Company shall be addressed to such
party at the last address on your records, provided that in case you in your
sole discretion shall determine that an emergency exists, you may use such
other means of communication as you shall deem advisable.

      7.       You are under no duty to supervise, recommend or advise 






                                      -64-
<PAGE>   65
the Collateral Agent relative to the investment, purchase, sale, retention
or other disposition of any property held hereunder unless specifically provided
for by the Custodial Agreement.

      8.       With respect to any direction to receive securities in
transactions not placed through you, you shall have no duty or responsibility
to advise the Company of non-receipt, or to take any steps to obtain delivery
of securities from any brokers or dealers.  All dealer concessions made to you
will be retained by you unless specifically agreed to the contrary by you.

      9.       Notwithstanding anything herein to the contrary, unless
instructions are received from the Collateral Agent, specifying a different
destination than the address listed on your records for the Collateral Agent,
within ten (10) days of the receipt of any termination notice, you shall have
the right to transfer all securities and other property held by you or any
depositary in connection with the Custodial Agreement or registered in your
name to the Collateral Agent at the address listed on your records.
