                    -------------------------------------------------------
     3.1  The Closing.
          ----------- 

          The purchase and sale of the Business Assets of each Seller (the
"Closing") shall take place concurrently at the offices of Rubin Baum Levin
Constant & Friedman, 30 Rockefeller Plaza, 29th Floor, New York, New York 10112,
at 10:00 A.M. on the third Business Day following the satisfaction or waiver of
all conditions to the obligations of the Designated Buyers and Sellers to
consummate the transactions contemplated hereby (other than conditions with
respect to actions the respective party will take at the Closing itself) or at
such other place and/or other date as the parties may mutually agree (the
"Closing Date").  In no event shall the Closing Date be later than September 1,
1996.  The parties hereto agree that the purchase of the Business Assets of one
Seller cannot be consummated unless the purchase of the Business Assets of the
other Seller is concurrently consummated hereunder.

     3.2  Purchase Price.
          -------------- 

                                      -16-
<PAGE>
 
     (a) Subject to any adjustment pursuant to Section 3.2(b) hereof, the
purchase price for the sale of NMPC's Business Assets (the "NMPC Purchase
Price") and the purchase price for the sale of EDDY'S Business Assets (the "EDDY
Purchase Price;" and collectively with the NMPC Purchase Price, the "Purchase
Price") shall be an aggregate of $55,638,000, to be allocated by the parties
hereto between the NMPC Purchase Price and the EDDY Purchase Price (the
"Allocated Purchase Prices") within twenty days after the date hereof (the
"Deadline"), plus in each case the assumption of liabilities provided for in
Section 3.3 hereof, payable at the Closing by the Applicable Designated Buyer by
wire transfer of immediately available funds in the amounts and to the
respective accounts of the Sellers to be furnished by the respective Sellers to
the Applicable Designated Buyer prior to the Closing Date.

          If the parties fail to agree on the Allocated Purchase Prices by the
Deadline, on the first Business Day thereafter Sellers and Designated Buyers
shall either agree upon a firm of certified public accountants to determine the
Allocated Purchase Prices or shall each select a firm of certified public
accountants of nationally recognized standing in order for such two firms to
select on the second Business Day after the Deadline a third firm of certified
public accountants to determine the Allocated Purchase Prices.  If by the end of
the fifth Business Day after the Deadline, a firm has not yet been selected
pursuant to the foregoing procedures to determine the Allocated Purchase

                                      -17-
<PAGE>
 
Prices, then the firm shall be a firm of certified public accountants designated
by the American Arbitration Association at the request of any party.  The firm
engaged shall be requested to determine the Allocated Purchase Prices no later
than the fifteenth Business Day after the Deadline, and its decision shall be
final and binding upon the parties.  The parties shall be responsible for their
respective expenses in connection with this determination, except that the fees
of the firm agreed upon by the parties (or otherwise designated to determine the
Allocated Purchase Prices in accordance herewith) shall be divided equally
between Designated Buyers, on the one hand, and Sellers, on the other.

     (b) Promptly following the Closing Date (but in any event no later than
seventy five days after the Closing Date) Sellers shall, at the expense of
Designated Buyers and Sellers to be shared equally, prepare a combined balance
sheet for Sellers' Businesses (after eliminating the Excluded Assets and the
Excluded Liabilities), as at the Closing Date (the "Closing Balance Sheet") in a
manner consistent with the preparation of the Pro Forma Financial Statements
which shall be reported on without qualification by the independent auditing
firm of one of the Sellers.  If Designated Buyers do not give written notice to
Sellers setting forth detailed objections to the Closing Balance Sheet (the
"Objection Notice") within 20 days of said delivery, it shall be final and
binding on the parties.  If there is a dispute between Sellers and Designated
Buyers with respect to the

                                      -18-
<PAGE>
 
Closing Balance Sheet and Sellers and Designated Buyers are unable to resolve
such dispute within 15 days of receipt of the Objection Notice, such dispute
shall be resolved as expeditiously as possible by a firm of certified public
accountants mutually acceptable to the parties.  If the parties are unable to
agree upon a firm of certified public accountants within 5 days, then Sellers
and Designated Buyers shall within 5 days thereafter, by notice to the other,
set forth the name of a firm of certified public accountants.  The two firms
designated by the parties shall as promptly as possible select a third firm of
certified public accountants to resolve the dispute; provided, however, that if
the firms are unable to agree upon a third firm within seven Business Days after
the second of such firms is selected or if Sellers or Designated Buyers fail to
select a firm, then the third firm of certified public accountants shall be a
firm of certified public accountants designated by the American Arbitration
Association at the request of any party.  The decision of the firm of certified
public accountants mutually acceptable to the parties (or such other firm of
certified public accountants designated in accordance herewith to resolve the
dispute) shall be final and binding upon Sellers and Designated Buyers and the
Closing Balance Sheet as approved by such firm of certified public accountants
shall be the Closing Balance Sheet hereunder.  The parties shall be responsible
for their respective expenses in connection with such resolution, except for the
fees of the firm of certified public accountants mutually acceptable to the par-

                                      -19-
<PAGE>
 
ties (or the third accounting firm designated in accordance herewith) which
shall be divided equally between Designated Buyers, on the one hand, and
Sellers, on the other.  In the event that the combined working capital of
Sellers' Businesses (computed by subtracting the current liabilities from the
current assets (excluding deferred taxes and eliminating Excluded Assets,
including, without limitation, prepaid insurance, and Excluded Liabilities), all
as set forth in the Closing Balance Sheet)), is greater or less than
$10,638,000, Designated Buyers shall pay to Sellers, in the aggregate, the
amount of such excess, allocated as specified by Sellers, or Sellers shall pay
to Designated Buyers, in the aggregate, the amount of such shortfall, allocated
as specified by Designated Buyers, in cash within five days after the delivery
of the Closing Balance Sheet.

Designated Buyer, in its sole discretion, may modify the terms and conditions of

     (b) Medical, Insurance and Other Benefits. (1)  (A)  All expenses or
         -------------------------------------                           
claims covered under medical, travel accident, accidental death and

incurred by Employees and their dependents before the Closing Date, irrespective
of the time at which claims are presented, are the responsibility of such Seller
and shall be paid directly by such Seller or its insurance carrier to such

provide Continued Employees and their dependents and may modify or terminate
such plan at any time; provided, however, that effective as of the Closing Date,

such coverage on reasonable terms.  Each respective Seller agrees to provide
Applicable Designated Buyer such information as it may request for purposes of

the Closing Date with respect to any Employees and their dependents.  Each
Designated Buyer shall fulfill all such obligations with respect to any
"qualifying event" that occurs after the Closing Date with respect to any
Continued Employees and their dependents.

(b)(4) shall require Applicable Designated Buyer to provide any severance pay
benefits, medical coverage, vacation, or other benefits to any employee or
former employee except as expressly provided elsewhere in this Agreement,
including this Section 6.1.  Except as expressly provided elsewhere in this
Agreement, including this Section 6.1, each Applicable Designated Buyer reserves
the sole right to design, structure, amend or terminate any severance plan,
medical plan, vacation policy, or other plan or policy as it sees fit.

          (5) With respect to Continued Employees, Applicable Designated Buyer
shall continue to apply the vacation policy of the respective Seller or any
Affiliate thereof that is currently in effect (the "Seller's Vacation Policy")
at least until December 31, 1996 so that each Continued Employee shall be
entitled to use any vacation time and receive any vacation pay to

                                      -57-

Affiliate thereof for purposes of all vacation policies of Applicable Buyer

permitted by law, the Applicable Designated Buyer shall cause each Continued
Employee to be granted credit for service with Seller or any affiliate thereof
for purposes of eligibility and vesting in such Designated Buyer's Plan.

Designated Buyer shall give notice of its intention to do so to the respective
Seller.  If such Seller shall notify the Applicable Designated Buyer that it
wishes to retain any of such files, lists, records, manuals or books of account
which such Designated Buyer intends to destroy, the Applicable Designated Buyer
shall (at such Seller's expense) deliver such files, lists,

     breach or (B) if the Closing shall not have occurred on or before September
     1, 1996, by reason of the failure of any condition precedent under Section

     itself breaching any representation, warranty, or covenant contained in
     this Agreement); and

          (iii) Sellers may terminate this Agreement by giving written notice to
     Designated Buyers at any time prior to the Closing (A) in the event Parent

from a willful breach of any party to this Agreement, such party shall be fully
liable for any and all losses and damages incurred or suffered by the other

             (1) Except for the representation and set forth in Sections 4.1(d),

             (3) The representations and warranties made by Sellers in Sections

          (b) Each of the parties acknowledges that there are no representations

indemnification, contribution or right over, or from and against, any Person who

<PAGE>
 
contribution from Persons other than a party hereto, but its failure to make any
such recovery shall not serve to limit or impair its rights under this Article
9.

     9.2  Seller's Indemnification.  Subject to the limitations and restrictions
          ------------------------                                              
contained elsewhere in this Article 9, each Seller hereby agrees (severally and
not jointly) to indemnify, defend and hold the Applicable Designated Buyer and
Parent, their Affiliates, successors and assigns and their respective
representatives (collectively, "Buyer's Indemnitees") harmless from and against
any and all losses that such Buyer's Indemnitees may at any time suffer or
incur, or become subject to, as a result of or in connection with (i) any breach
or inaccuracy of any of the representations and warranties made by such Seller
in or pursuant to this Agreement if asserted by Buyer's Indemnitees during the
period that such representations and warranties survive; (ii) any failure by
such Seller to carry out perform, satisfy and discharge any of its covenants,
agreements, undertakings, liabilities or obligations under this Agreement or
under any of the documents and instruments delivered by such Seller pursuant to
this Agreement; (iii) claims by third parties against the Applicable Designated
Buyer relating to the operation and ownership by such Seller of the Business
Assets, the performance by such Seller under the Assumed Liabilities, the
conduct of the business of such Seller prior to the Closing Date and the
performance by Seller under the Excluded Liabilities and (iv) indebtedness, if
any, of the Sellers which Applicable Designated

                                      -69-
<PAGE>
 
Buyer pays to BLM pursuant to the letter from Designated Buyers to BLM attached
hereto as Schedule 9.2.  Notwithstanding the foregoing, Sellers shall not be
required to indemnify Buyer's Indemnitees under this Section 9.2 (other than
under clause (iv) above) unless and until the aggregate amount of such losses
shall exceed $250,000 at which time Sellers will be obligated to indemnify
Buyer's Indemnitees for all additional losses in excess of $250,000; provided,
                                                                     -------- 
however, in no event shall Sellers be liable to Buyer's Indemnitees hereunder

(including pursuant to (iv) above) for an amount in excess of $5,000,000 (in the
aggregate for both Sellers and for Buyer's Indemnitees of both Designated
Buyers).

     9.3  Designated Buyer's Indemnification.  The Designated Buyers hereby
          ----------------------------------                               
jointly and severally agree to indemnify, defend and hold each Seller, its
Affiliates, successors and assigns and their respective representatives
(collectively, "Seller's Indemnitees") harmless from and against any and all
losses that Seller's Indemnitees may at any time suffer or incur, or become
subject to, as a result of or in connection with (i) any breach or inaccuracy of
any of the representations and warranties made by Parent or a Designated Buyer
in or pursuant to this Agreement; (ii) any failure of a Designated Buyer to
carry out, perform, satisfy and discharge any of its covenants, agreements,
undertakings, liabilities or obligations under this Agreement or under any of
the documents and instruments delivered by a Designated Buyer pursuant to this
Agreement; and (iii) claims by third par-

                                      -70-
<PAGE>
 
ties against a Seller or its Affiliates relating to the operation and ownership
by a Designated Buyer of the Business Assets, the performance by a Designated
Buyer under the Assumed Liabilities and the conduct of the business of a
Designated Buyer (so long as such claims or losses arise from events that
occurred after the Closing Date).

     9.4  Defense of Claims.  A Seller and a Designated Buyer shall each give
          -----------------                                                  
prompt notice to the other of any claim against the party giving notice which
might give rise to a claim based upon any indemnity contained herein.  The
notice shall set forth in reasonable detail the nature and basis of the claim
and the actual or estimated amount thereof.  The failure to provide such notice
promptly will not relieve the indemnifying party of its obligations under
Article 9 unless and only to the extent that the failure to give such notice
promptly materially prejudiced the ability of the indemnifying party to defend
against such claim.  In the event any action, suit or proceeding is brought
against a party with respect to which the other party hereto may have liability
under any indemnity contained herein, the indemnifying party shall have the
right, at its sole cost and expense, to defend such action in the name and on
behalf of the indemnified party with counsel reasonably satisfactory to the
indemnified party.  The parties hereto agree to render to each other such
assistance as may reasonably be required in order to ensure the proper and
adequate defense of any such action, suit or proceeding.  The indemnified party
shall have the right to partici-

                                      -71-
<PAGE>
 
pate, at its own expense and with counsel of its choosing, in the defense of any
claim against which it is indemnified hereunder and it shall be kept fully
informed with respect thereto.  The party seeking indemnification hereunder
shall not make any settlement of any claim which might give rise to liability of
another party under any indemnity contained herein without the prior written
consent of such other party, which consent shall not be unreasonably withheld.

     9.5  Guarantee.  NMPC covenants that on or prior to Closing, it will
          ---------                                                      
deliver to MI a guarantee of Cedar, in a form reasonably satisfactory to MI, of
NMPC's obligations under Section 9.2.  EDDY covenants that on or prior to
Closing, it will deliver to MII a guarantee of Trans-Resources, Inc. ("TRI"), in
a form reasonably satisfactory to MII, of EDDY's obligations under Section 9.2.

principal balance of all Syndicated Loans, Swingline Loans and Letter of Credit
Obligations would exceed the then applicable Maximum Commitment; provided

Bank's Three Year Commitment to all Three Year Commitments and/or each Bank's

          (a)  Notices.  Whenever the Borrowers desire a Syndicated Loan advance
               -------

     (confirmed immediately thereafter in writing) (a "Notice of Borrowing") on
                                                       -------------------     
     behalf of all Borrowers to the Agent in the form attached hereto as Exhibit
                                                                         -------

     Business Day of the requested advance in the case of Base Rate Loans and on
     the third Business Day prior to the requested advance in the case of
     Eurodollar Loans.  Each such notice shall be irrevocable and shall specify
     (i) that a Syndicated Loan advance is requested and indicating whether it
     is to be funded under the Three Year Facility or the 364 Day Facility, (ii)
     the date of the requested Syndicated Loan advance (which shall be a
     Business Day), (iii) the aggregate principal amount of Syndicated Loan
     advances requested, and (iv) whether the Syndicated Loan advance requested
     shall consist of Base Rate Loans, Eurodollar Loans, or a combination
     thereof, and if Eurodollar Loans, the Interest Periods with respect
     thereto.  If MCC shall fail to specify in any Notice of Borrowing (A) the
     type of Facility, then such notice shall be deemed a request for an advance
     under the Three Year Facility, or, if it has been fully funded, under the
     364 Day Facility, (B) an applicable Interest Period in the case of a
     Eurodollar Loan, then such notice shall be deemed to be a request for an
     Interest Period of one month, or (C) the type of Syndicated Loan requested,
     then such notice shall be deemed to be a request for a Base Rate Loan
     hereunder.  The Agent shall as promptly as practicable give each Bank
     notice of each requested Syndicated Loan advance, of such Bank's pro rata
     share thereof and of the other matters covered in the Notice of Borrowing.

          (b)  Minimum Amounts.  The aggregate minimum principal amount of each
               ---------------                                                 
     Syndicated Loan advance hereunder shall be not less than $2,500,000 (and
     integral multiples of $100,000.00 in excess thereof); provided, Eurodollar
     Loan advances shall be in the minimum amount of $2,500,000.00 and shall be
     in integral multiples of $250,000.00 in excess thereof.

          (c)  Advances.  Each Bank will make its pro rata share of each
               --------                                                 
     Syndicated Loan advance available to the Agent by 1:00 p.m. (Charlotte,
     North Carolina time) on date specified in the Notice of Borrowing by
     deposit in U.S. dollars of immediately available funds to account number
     0112500392 at the offices of the Agent in Nashville, Tennessee as provided
     in the signature pages, or at such other address as the Agent may designate
     in writing.  All Syndicated Loan advances shall be made by the Banks pro
     rata on the basis of each Bank's Three Year Commitment or 364 Day
     Commitment, as the case may be, to the total Three Year Commitments or 364
     Day Commitments, respectively, then in effect.  No Bank shall be
     responsible for the failure or delay by any other Bank in its obligation to
     make Syndicated Loan advances provided, however, that the failure of any
     Bank to fund its Commitments hereunder shall not relieve any other 

                                      17

     Bank of its Commitments hereunder. Unless the Agent has been notified by
     any Bank prior to the making of any such Syndicated Loan advance that such
     Bank does not intend to make available to the Agent its portion of the
     Syndicated Loan advance to be made on such date, the Agent may assume that
     such Bank has made such amount available to the Agent on the date of such
     Syndicated Loan advance, and the Agent, in reliance upon such assumption,
     may (in its sole discretion without any obligation to do so) make available
     to the Borrowers a corresponding amount. If such corresponding amount is
     not in fact made available to the Borrowers, the Agent shall be entitled to
     recover such corresponding amount from such Bank. If such Bank does not pay
     such corresponding amount forthwith upon the Agent's demand therefor, the
     Agent will promptly notify the Borrowers and the Borrowers shall
     immediately pay such corresponding amount to the Agent. The Agent shall
     also be entitled to recover from such Bank or the Borrowers, as the case
     may be, interest on such corresponding amount in respect of each day from
     the date such corresponding amount was made available by the Agent to the
     Borrowers to the date such corresponding amount is recovered by the Agent,
     at a per annum rate equal to (i) if paid by such Bank, within two Business
     Days of making such corresponding amount available to the Borrowers, the
     overnight Federal Funds Rate, and thereafter the Base Rate, and (ii) if
     paid by the Borrowers, the then applicable rate calculated in accordance
     with Section 2.4.

          (c)  Swingline Bank Notices.  At any time from the date on which a
               ----------------------                                       
     Swingline Loan is made until such Swingline Loan shall have been paid in
     full, the Swingline Bank may in its sole discretion, and the Borrowers
     hereby irrevocably authorize and empower (which power is coupled with an
     interest) the Swingline Bank to, deliver, on behalf of the Borrowers, to
     the Agent a notice of borrowing of Syndicated Loans that are Base Rate
     Loans in an amount equal to the then unpaid principal amount of such
     Swingline Loan together with all accrued and unpaid interest, which
     borrowing shall not be subject to the provisions of Section 2.8.  The
     proceeds of such Syndicated Loans shall be applied solely to refinance such
     Swingline Loan.  In the event that the power of the Swingline Bank to give
     such notice of borrowing on behalf of the Borrowers is terminated for any
     reason whatsoever (including a termination resulting from the occurrence of
     an event specified in Section 8.1.6 or 8.1.7 of Article VIII with respect
     to the Borrowers), or the Swingline Bank is otherwise precluded for any
     reason whatsoever from giving a notice of borrowing on behalf of the
     Borrowers as provided in the preceding sentence, each Bank shall, upon
     notice from the Swingline Bank, promptly purchase from the Swingline Bank a
     participation in (or, if and to the extent specified by the Swingline Bank,
     a direct interest in) such Swingline Loan in the amount of such Loan it
     would have been obligated to make pursuant to such notice of borrowing.
     Anything in Section 2.2(a) to the contrary notwithstanding, each Bank
     shall, not later than 4:00 p.m. (Charlotte, North Carolina time) on the
     Business Day on which such notice is given (if such notice is given by 2:15
     p.m. (Charlotte, North Carolina time)) or 9:00 a.m. (Charlotte, North
     Carolina time) on the next succeeding Business Day (if such notice is given
     after 2:15 p.m. (Charlotte, North Carolina time)), make available the
     amount of such Loan to be made by it (or the amount of the participation or
     direct interest to be purchased by it, as the case may be) to the Agent at
     the account specified in Section 2.2(c) and the amount so received by the
     Agent shall be made available to the Swingline Bank by depositing the same,
     in immediately available funds, in an account of the Swingline Bank at the
     office designated by the Swingline Bank.  Promptly following its receipt of
     any payment in respect of a Swingline Loan, the Swingline Bank 

                                      18
<PAGE>
 
     shall pay to each Bank that has acquired a participation in such Loan such
     Bank's proportionate share of such payment.

          Anything in this Agreement to the contrary notwithstanding (including
     in Section 2.8), the obligation of each Bank to make its Base Rate Loan (or
     purchase its participation or direct interest in the Swingline Loan, as the
     case may be) pursuant to this Section 2.2(d) is unconditional under any and
     all circumstances whatsoever and shall not be subject to set-off,
     counterclaim or defense to payment that such Bank may have or have had
     against the Borrowers, the Agent, Swingline Bank or any other Bank and,
     without limiting any of the foregoing, shall be unconditional irrespective
     of (i) the occurrence of any Event of Default or Potential Default, (ii)
     the financial condition of the Borrowers, any Subsidiary or Affiliate of
     the Borrowers, the Agent, the Swingline Bank or any other Bank or (iii) the
     termination or cancellation of the Commitments (provided that such
     Swingline Loan was made prior to the date of such termination or
     cancellation).  The Borrowers agree that any Bank so purchasing a
     participation (or direct interest) in such Swingline Loan may exercise all
     rights of set-off, bankers' lien, counterclaim or similar rights with
     respect to such participation as fully as if such Bank were a direct holder
     of a Swingline Loan in the amount of such participation.

          If any Bank shall default in its obligation to make its Base Rate Loan
     to refinance any Swingline Loan (or purchase its participation or direct
     interest in such Swingline Loan, as the case may be) pursuant to the first
     paragraph of this Section 2.2(d), then for so long as such default shall
     continue, the Agent shall at the request of the Swingline Bank, withhold
     from any payments received by the Agent under this Agreement or any Note
     for account of such Bank the amount so in default, and the Agent shall pay
     the same to the Swingline Bank up to the amount and in satisfaction of such
     defaulted obligation, which amount the Swingline Bank will apply to the
     repayment of the principal of such Swingline Loan (if such Bank defaulted
     in its obligation to make its Base Rate Loan) or otherwise to the purchase
     of the participation or direct interest to be purchased by such Bank.

     2.3  Repayment.  The Syndicated Loans hereunder shall be due and payable in
          ---------                                                             
full on their respective Termination Dates and in accordance with whether they
were advanced under the Three Year Facility or the 364 Day Facility.

     2.4  Interest.  Subject to the provisions of Section 3.1, Syndicated Loans
          --------

     consist of Base Rate Loans, at a per annum rate equal to the Base Rate plus
     the Applicable Base Rate Margin, said rate to change contemporaneously with
     any change in the Base Rate.

          (b)  Eurodollar Loans.  During such periods as Syndicated Loans shall

     date of this Agreement to but not including the Termination Date of the
     Three Year Facility in an aggregate principal amount at any one time
     outstanding up to but not exceeding the Swingline Sublimit; provided that
                                                                 --------     
     the Swingline Bank shall not make any Swingline Loan pursuant hereto if (i)

          (a)  Issuance. Subject to the terms and conditions hereof, the Letter
               --------                                                        
     of Credit Bank has issued the Letters of Credit described in Exhibit 2.7
                                                                  -----------
     hereof (which Letters of Credit shall be deemed issued and outstanding
     hereunder upon the effectiveness of this Loan Agreement) and the Letter of
     Credit Bank will from time to time issue standby letters of credit and
     commercial letters of credit from the Closing Date to, but not including,
     the Three Year Facility Termination Date as the Borrowers may request, each
     to be in a form acceptable to the Letter of Credit Bank (hereinafter the
     Letters of Credit described on Exhibit 2.7 and the standby letters of
                                    -----------                           
     credit and commercial letters of credit issued on and after the Closing
     Date pursuant to this Section 2.7, together with all extensions, renewals,
     modifications and replacements thereto, shall be referred to as the
     "Letters of Credit"); provided, however, the Letter of Credit Bank shall
      ------------------    --------  -------                                 
     issue any Letter of Credit to the extent that immediately after the
     issuance of such Letter of Credit the sum of the outstanding principal
     balance of all Syndicated Loans and Swingline Loans outstanding under the
     Three Year Facility plus the amount of all Letter of Credit Obligations
     would exceed the then aggregate Three Year Commitments of the Banks;
     provided further, the Letter of Credit Bank shall not issue any Letter of
     -------- -------                                                         
     Credit to the extent that immediately after the issuance of such Letter of
     Credit the Letter of Credit Obligations relating to all Letters of Credit
     would exceed $25,000,000; provided further, the Letters of Credit shall be
                               -------- -------                                
     issued solely for the general corporate purposes of the Borrowers and shall
     be jointly and severally binding on each of Borrowers, regardless of
     whether any application is signed by one or more of the Borrowers.  No
     Letter of Credit shall be automatically renewable or have an expiry date
     extending beyond the fifth (5th) Business Day preceding the Termination
     Date of the Three Year Facility.

          (b)  Notice.  The request for the issuance of a Letter of Credit shall
               ------                                                           
     be submitted to the Letter of Credit Bank and the Agent (if different) at
     least three Business Days prior to the requested date of issuance.  Upon
     issuance of a Letter of Credit, the Agent shall promptly notify the Banks
     of the amount and terms thereof.  The Letter of Credit Bank shall notify
     the Agent promptly of all payments, reimbursements, extensions,
     expirations, transfers and other activity with respect to outstanding
     Letters of Credit.  Upon the request of any Bank, the Agent shall promptly
     notify such Bank of all of such payments, reimbursements, expirations,
     transfers and other activity with respect to outstanding Letters of Credit.

          (c)  Participations.  Each Bank shall be deemed to have purchased,
               --------------                                               
     without recourse to the Letter of Credit Bank, a participation from the
     Letter of Credit Bank in each Letter of Credit issued or deemed issued
     hereunder, in each case in an amount equal to its pro rata share (based
     upon its Three Year Commitment to all Three Year Commitments) of the amount
     of such Letter of Credit.  Without limiting the scope and nature of each
     Bank's participation in any Letter of Credit, to the extent that the Letter
     of Credit Bank has not been reimbursed by the Borrowers for any payment
     required to be made by the Letter of Credit Bank under any Letter of
     Credit, each Bank shall pay to the Agent for payment to the Letter of
     Credit Bank each Bank's pro rata share of such unreimbursed drawing in same
     day funds on the day of notification by the Letter of Credit Bank of an
     unreimbursed drawing pursuant to the provisions of subsection 2.7(d) 

                                      21
<PAGE>
 
     (or on the next Business Day if such notification is made after 2:00 p.m.
     Charlotte time); provided, however, the Banks shall not be obligated to
     reimburse the Letter of Credit Bank as provided above to the extent that
     such reimbursement obligation has arisen solely on account of the gross
     negligence or willful misconduct of the Letter of Credit Bank, as
     determined by a court of competent jurisdiction. The obligation of each
     Bank to so reimburse the Letter of Credit Bank shall be absolute and
     unconditional and shall not be affected by the occurrence of a Potential
     Default, an Event of Default or any other occurrence or event. Any such
     reimbursement shall not relieve or otherwise impair the obligation of any
     Borrower to reimburse the Letter of Credit Bank under any Letter of Credit,
     together with interest as hereinafter provided.

          (d)  Reimbursement.  In the event of any drawing under any Letter of
               -------------                                                  
     Credit, the Letter of Credit Bank will promptly notify the Borrowers and
     the Agent.  Unless the Borrowers shall immediately notify the Letter of
     Credit Bank of their intent to otherwise reimburse the Letter of Credit
     Bank, the Borrowers shall be deemed to have jointly and severally requested
     a Base Rate Loan under the Three Year Facility in the amount of the
     drawing, the proceeds of which will be used to satisfy the reimbursement
     obligations of the Borrowers to the Letter of Credit Bank in connection
     with such drawing.  The Borrowers shall reimburse the Letter of Credit Bank
     on the day of such drawing under any Letter of Credit (either with the
     proceeds of a Syndicated Loan obtained hereunder or otherwise) in same day
     funds as provided in the Letter of Credit Application.  If for any reason
     the Borrowers cannot draw under the Three Year Facility or shall otherwise
     fail to reimburse the Letter of Credit Bank as provided hereinabove, the
     unreimbursed amount of such drawing shall bear interest at a per annum rate
     equal to the Base Rate plus 2%.  The Borrowers' reimbursement obligations
     hereunder shall be absolute, unconditional and joint and several under all
     circumstances irrespective of any rights of set-off, counterclaim or
     defense to payment any Borrower may claim or have against the Letter of
     Credit Bank, the Agent, the Banks, the beneficiary of any Letter of Credit
     or any other Person, including without limitation any defense based on any
     failure of the Borrowers to receive consideration or the legality,
     validity, regularity or unenforceability of the Letter of Credit.  The
     Letter of Credit Bank will promptly notify the Agent and the Agent will
     promptly notify the other Banks of the amount of any unreimbursed drawing
     and each Bank will promptly pay the Letter of Credit Bank for its pro rata
     share of such unreimbursed drawing as provided in subsection 2.7(c).
 
          (e)  Modification, Extension.  The issuance of any supplement,
               -----------------------                                  
     modification, amendment, renewal, or extension to any Letter of Credit
     shall, for purposes hereof, be treated in all respects the same as the
     issuance of a new Letter of Credit hereunder.

          (f)  Indemnification; Nature of Letter of Credit Bank's Duties. (1) In
               ---------------------------------------------------------
     addition to its other obligations under this Section 2.7, the Borrowers
     hereby agree to protect, indemnify, pay and save the Letter of Credit Bank
     and each Bank harmless from and against any and all claims, demands,
     liabilities, damages, losses, costs, charges and expenses (including
     reasonable attorneys' fees) that the Letter of Credit Bank or any Bank may
     incur or be subject to as a consequence, direct or indirect, of (A) the
     issuance of any Letter of Credit or (B) the failure of the Letter of Credit
     Bank to honor a drawing under a Letter of Credit as a result of any act or
     omission, whether rightful or wrongful, of any present or future de jure or
     de facto government or governmental authority (all such acts or omissions,
     herein called "Government Acts") or (C) any action or nonaction taken at
                    ---------------
     any Borrower's request with respect to any Letter of Credit.

                                      22
<PAGE>
 
          (2)  As between the Borrowers on the one hand and the Letter of Credit
     Bank and the Banks on the other hand, the Borrowers shall assume all risks
     of the acts, omissions or misuse of any Letter of Credit by the beneficiary
     thereof.  The Letter of Credit Bank and the Banks shall not be responsible:
     (A) for the form, validity, sufficiency, accuracy, genuineness or legal
     effect of any document submitted by any party in connection with the
     application for, issuance of and drawing under any Letter of Credit, even
     if it should in fact prove to be in any or all respects invalid,
     insufficient, inaccurate, fraudulent or forged; (B) for the validity or
     sufficiency of any instrument transferring or assigning or purporting to
     transfer or assign any Letter of Credit or the rights or benefits
     thereunder or proceeds thereof, in whole or in part, that may prove to be
     invalid or ineffective for any reason; (C) for the performance of any
     beneficiary of a Letter of Credit of its obligations to the Borrowers or
     any failure of any such beneficiary to comply fully with conditions
     required in order to draw upon a Letter of Credit; (D) for errors,
     omissions, interruptions or delays in transmission or delivery of any
     messages, by mail, cable, telegraph, telex or otherwise, whether or not
     they be in cipher; (E) for errors in interpretation of technical terms; (F)
     for any loss or delay in the transmission or otherwise of any document
     required in order to make a drawing under a Letter of Credit or of the
     proceeds thereof; and (G) for any consequences arising from causes beyond
     the control of the Letter of Credit Bank or any Bank, including, without
     limitation, any Government Acts.  None of the above shall affect, impair,
     or prevent the vesting or enforcement of the Letter of Credit Bank's or any
     Bank's rights or powers hereunder.

          (3)  In issuing each Letter of Credit, the Letter of Credit Bank is
     expressly authorized to make changes from the terms set forth in the
     request for such Letter of Credit as the Letter of Credit Bank, in its sole
     discretion, may deem advisable, provided that no such changes will vary the
     principal terms thereof.  Except as otherwise expressly agreed herein or in
     any particular instance, all Letters of Credit issued hereunder shall be
     subject to the "Uniform Customs and Practices for Documentary Credits"
     (1993 Revision), International Chamber of Commerce Publication No. 500.

          (4)  If there is any discrepancy between the documents accompanying a
     draft or other demand for payment or acceptance under a Letter of Credit
     and the specifications for such documents in the Borrowers' request for
     such letter of Credit or the Letter of Credit, and either (A) the Letter of
     Credit Bank delivers telephonic or written notice to MCC's principal office
     of such discrepancy, and the Borrowers do not deliver telephonic or written
     instruction to the Letter of Credit Bank's letter of credit department to
     dishonor the draft or demand by noon (Charlotte, North Carolina time) for
     the Letter of Credit Bank on the Business Day after the Business Day on
     which the Letter of Credit Bank shall have delivered notice to the
     Borrowers of the discrepancy, or (B) in the case of a commercial Letter of
     Credit, the Borrowers have obtained possession of the goods that are the
     subject of such Letter of Credit; then the Letter of Credit Bank may
     conclusively presume that the Borrowers have waived any objection to
     payment or acceptance, as the case may be, based on such discrepancy, and
     the Letter of Credit Bank may, but shall not be obligated to, honor the
     draft or other demand under the Letter of Credit (and may honor such draft
     after noon on such Business Day, if such Business Day is the last day to
     which the Letter of Credit Bank is entitled to defer honor of such draft
     under applicable law).  In such event, the Borrowers shall be liable to the
     
                                      23
<PAGE>
 
     Letter of Credit Bank pursuant to subsection 2.7(d) as if the discrepancy
     had not been in the documents.

          (5)  In furtherance and extension and not in limitation of the
     specific provisions hereinabove set forth, any action taken or omitted by
     the Letter of Credit Bank or any Bank, under or in connection with any
     Letter of Credit or the related documents, if taken or omitted in good
     faith, shall not put such Letter of Credit Bank or such Bank under any
     resulting liability to the Borrowers. It is the intention of the parties
     that this Loan Agreement shall be construed and applied to protect and
     indemnify the Letter of Credit Bank and the Banks against any and all risks
     involved in the issuance of the Letters of Credit, all of which risks are
     hereby assumed by the Borrowers, including, without limitation, whether
     rightful or wrongful, of any present or future Government Acts. The Letter
     of Credit Bank and the Banks shall not, in any way, be liable for any
     failure by the Letter of Credit Bank or anyone else to pay any drawing
     under any Letter of Credit as a result of any Government Acts or any other
     cause beyond the control of the Letter of Credit Bank.

          (6)  Nothing in this subsection (f) is intended to limit the
     reimbursement obligation of any Borrower contained in subsection 2.7(d).
     The obligations of the Borrowers under this subsection (f) shall survive
     the termination of this Loan Agreement.  No act or omissions of any current
     or prior beneficiary of a Letter of Credit shall in any way affect or
     impair the rights of the Letter of Credit Bank or any Bank to enforce any
     right, power or benefit under this Loan Agreement.

          (7)  Notwithstanding anything to the contrary contained in this
     subsection (f), the Borrowers shall have no obligation to indemnify any
     Letter of Credit Bank or any Bank in respect of any liability incurred by
     such Letter of Credit Bank or such Bank arising solely out of the gross
     negligence or willful misconduct of the Letter of Credit Bank or such Bank
     in connection with issuing a Letter of Credit, as the case may be, as
     finally determined by a court of competent jurisdiction.

     For purposes of the foregoing, the undisbursed amount of each Bank's Three
     Year Commitment shall mean, from time to time, the Three Year Commitment of
     such Bank minus such Bank's pro rata share of the then outstanding

     Facility (but not Swingline Loans) and the Letter of Credit Obligations.
     Said Non- Use Fee shall be calculated on a 360 day year counting the actual
     number of elapsed days.  Accrued fees shall be payable in arrears on each
     Quarterly Date and on the earlier of the date such Commitment is terminated
     and the Three Year Facility Termination Date.  In the event the Borrowers
     fail to timely furnish to Agent any Compliance Certificate and related

     Compliance Certificate and related financial statements are required to be
     delivered and shall remain in effect until the Borrowers furnish them to
     the Agent and the same are approved by the Agent.

          undisbursed amount of such Bank's 364 Day Commitment at a rate equal
          to one-tenth of one percent per annum (0.10%). Said fees shall be
          payable quarterly in arrears on each Quarterly Date and shall be
          calculated on a 360 day year counting the actual number of elapsed
          days. Any accrued and unpaid fees hereunder shall be paid on the
          earlier of the date such Commitment is terminated and the 364 Day
          Facility Termination Date.

          (c)  Letter of Credit Fees.  The Borrowers shall pay to the Agent for

     advance on such date of issuance) plus all commissions, charges, costs and
     expenses in the amounts customarily charged by the Letter of Credit Bank
     from time to time in like circumstances with respect to the issuance of
     each Letter of Credit and drawings and other transactions relating to such
     Letter of Credit.  In addition, Borrowers shall pay to the Agent for the
     account of each Bank a letter of credit fee in respect of each Letter of
     Credit on the daily average undrawn face amount of such Letter of Credit
     for the period from and including the date of issuance of such Letter of
     Credit to and including the date such Letter of Credit is drawn in full,
     expires or is terminated (such fee to be non-refundable, to be paid in
     arrears on each Quarterly Date and on the Termination Date of the Three
     Year Facility and to be calculated, for any day, after giving effect to any
     payments made under such Letter of Credit on such day) in an amount equal
     to (a) for the First Quarterly Period, 0.50% per annum, and (b) thereafter,
     1.75% per annum or, for any Quarterly Period prior to the first day of
     which (and in any event no later than 45 days after the end of the fiscal
     quarter most recently ended) the Borrowers have delivered to the Agent a

     All calculations of Letter of Credit fees shall be based on a 360 day year

     fail to timely furnish to Agent any Compliance Certificate and related
     financial statements as required by this Loan Agreement, then the maximum
     percentage rate for Letter of Credit Fees shall

     apply from the date such Compliance Certificate and related financial
     statements are required to be delivered and shall remain in effect until
     the Borrowers furnish them to the Agent and the same are approved by the
     Agent.

          (d)  Agent's Fees.  The Borrowers shall pay to the Agent, for its own
               ------------

     letter agreement dated October 17, 1995 by and between MCC and the Agent,
     as such agreement may be modified and supplemented from time to time, the
     terms and provisions of which letter agreement are incorporated herein by
     reference.

     2.10 Reduction of Commitment.  The Borrowers shall have the right to reduce
          -----------------------                                               
the amount of the aggregate Commitments, at any time upon three (3) Business
Days notice to the Agent, in any integral multiple of Ten Million Dollars
($10,000,000.00); provided that the Commitments may not be reduced to an amount
less than the aggregate amount of the Loans and Letters of Credit then
outstanding.  The Borrowers shall further have the right to specify how the
reduction shall be applied to reduce the Three Year Facility and the 364 Day
Facility; provided, if the Borrowers fail to specify, then the reduction shall
be made to each Facility pro rata based on the ratio of the amount of the Three
                         --------                                              
Year Commitments and/or 364 Day Commitments, as the case may be, to the then
Maximum Commitment.  Each such reduction shall, unless otherwise agreed in
writing, reduce each Bank's Commitments pro rata in accordance with its
                                        --------                       
percentage amount of all outstanding Three Year Commitments and its percentage
amount (if different) of all 364 Day Commitments.  Contemporaneously with each
such reduction, the Borrowers shall repay to the Agent for the account of each
Bank in accordance with the foregoing percentages the amounts, if any, by which
the then outstanding principal balance of each Note exceeds each Commitment as
so reduced.  After each such reduction:  (i) the Borrowers shall immediately pay
the Agent any Non-Use Fees provided for in Section 2.9 with respect to the
amount by which the Commitments are so reduced, but only with respect to the
time any such Commitment existed and only to the extent not previously paid;
(ii) the Non-Use Fees provided for in Section 2.9 shall be calculated with
respect to the aggregate Commitments as so reduced; and (iii) the Commitments
may not be increased without the written consent of the Banks.

     2.11 Liability.  The unconditional liability of each Borrower for the
          ---------                                                       
entire Obligations shall not be impaired by any event whatsoever, including, but
not limited to, the merger, consolidation, dissolution, cessation of business or
liquidation of any Borrower; the financial decline or bankruptcy of any
Borrower; the failure of any other party to guarantee the Obligations or to
provide collateral therefor; any Bank's or Agent's compromise or settlement with
or without release of any Borrower; any Bank's or Agent's release of any
collateral for the Obligations, with or without notice to Borrowers; any Bank's
or Agent's failure to file suit against any Borrower (regardless of whether
Borrower is becoming insolvent, is believed to be about to leave the state or
jurisdiction or any other circumstance); any Bank's or Agent's failure to give
any Borrower notice of default; the unenforceability of the Obligations against
any Borrower due to bankruptcy discharge, counterclaim or for any other reason;
any Bank's or Agent's acceleration of the Obligations at any time; the
extension, modification or renewal of the Obligations; any Bank's or Agent's
failure to undertake or exercise diligence in collection efforts against any
party or property; the termination of any relationship of any Borrower with any
other Borrower, including, but not limited to, any relationship of commerce or
ownership; any Borrower's change of name or use of any name other than the name
used to identify such Borrower in this Agreement; or any Borrower's use of the
credit extended for any purpose whatsoever.  Should the liability of any
Borrower hereunder for the entire amount of the 

                                      27
<PAGE>
 
Obligations be subject to avoidance or limitation, notwithstanding the contrary
agreement and intention of the parties hereto, under any state or federal
fraudulent conveyance law or other similar law that may be determined to be
applicable, then the liability of such Borrower shall be limited to the maximum
amount for which the Borrower may be liable without legal impairment.

Event of Default hereunder, and regardless of whether the Loans have been
accelerated or not, the principal of and, to the extent permitted by law,
interest on all Loans hereunder and any other amounts owing hereunder or under
the other Loan Documents shall bear interest, payable on demand, at a per annum
rate 2% greater than the rate which would otherwise be applicable.  Likewise,
the Letter of Credit fees due in respect of the daily average undrawn amount of
each Letter of Credit as specified in Section 2.9(c) above shall be increased by
two percent (2%) per annum upon the occurrence and during the continuation of an
Event of Default hereunder.

     3.2  Prepayments.
          ----------- 

          (a)  Voluntary Prepayments.  The Borrowers shall have the right to
               ---------------------                                        
     prepay Syndicated Loans in whole or in part from time to time without
     premium or penalty without prior notice with respect to Base Rate Loans and
     upon one Business Day's prior written notice or telephonic notice
     (confirmed immediately thereafter in writing) to the Agent with respect to
     all other Loans; provided, however, that each such partial prepayment shall
     be a minimum principal amount of $2,500,000; provided further, the
     Borrowers shall pay all amounts payable under Section 3.6 hereof in
     connection with any such prepayment.  Swingline Loans may be prepaid in
     whole or in part at any time in any integral multiples of $1,000.  Amounts
     prepaid on the Loans may be reborrowed in accordance with the provisions
     hereof, subject to the approval of the Swingline Bank on Swingline Loans.
     If the Borrowers shall fail to specify the manner of application,
     prepayments shall be applied first to Swingline Loans, second to Base Rate
     Loans and third to Eurodollar Loans (taken as a group) in direct order of
     their Interest Period maturities.

          (b)  Mandatory Prepayments.  If at any time the sum of the outstanding
               ---------------------                                            
     principal balances of the Syndicated Loans, Swingline Loans and Letter of
     Credit Obligations shall exceed the then applicable Maximum Commitment,
     then the Borrowers shall immediately pay the Agent for the account of the
     Banks an amount equal to such excess.  If at any time the sum of the
     outstanding principal balances of the Syndicated Loans, Swingline Loans and
     Letter of Credit Obligations advanced and outstanding under the Three Year
     Commitments shall exceed the sum of the then applicable Three Year
     Commitments, then the Borrowers shall immediately pay the Agent for the
     account of the Banks an amount equal to such excess.  If at any time the
     sum of the outstanding principal balances of the Syndicated Loans disbursed
     under the then applicable 364 Day 

                                      28
<PAGE>
 
     Commitments shall exceed the sum of the 364 Day Commitments, then the
     Borrowers shall immediately pay the Agent for the account of the Banks an
     amount equal to such excess.

     3.3  Conversion.  The Borrowers shall have the option, on any Business Day,
          ----------                                                            
to extend existing Syndicated Loans into a subsequent Interest Period or to
convert Syndicated Loans into Syndicated Loans of another type; provided,
                                                                -------- 
however, that (i) except as provided in Section 3.4, Eurodollar Loans may be
converted into Loans of another type only on the last day of an Interest Period
applicable thereto, (ii) Eurodollar Loans may be extended, and Loans may be
converted into Eurodollar Loans, only if no Potential Default or Event of
Default is in existence on the date of extension or conversion, (iii) Loans
extended as, or converted into, Eurodollar Loans shall be in such minimum
amounts as provided in Section 2.2(b), and (iv) any request for extension or
conversion of a Eurodollar Loan which shall fail to specify an Interest Period
shall be deemed to be a request for an Interest Period of one month.  Each such
extension or conversion shall be effected by the Borrowers by having MCC on
behalf of the Borrowers give written notice (or telephone notice promptly
confirmed in writing) to the Agent (including requests for extensions and
renewals, a "Notice of Conversion") prior to 11:00 a.m. (Charlotte, North
             --------------------                                        
Carolina time) on the Business Day of, in the case of existing Base Rate Loans,
and on the third Business Day prior to, in the case of existing Eurodollar
Loans, the date of the proposed extension or conversion, specifying the date of
the proposed extension or conversion, the Syndicated Loans to be so extended or
converted, the types of Loans into which such Syndicated Loans are to be
converted and, if appropriate, the applicable Interest Periods with respect
thereto.  Each request for extension or conversion shall be deemed to be a
reaffirmation by the Borrowers that no Potential Default or Event of Default
then exists and is continuing and that the representations and warranties set
forth in Article V are true and correct in all material respects as of the date
of such Notice of Conversion (except to the extent they relate to an earlier
period).  In the event the Borrowers fail to request extension or conversion of
any Eurodollar Loan in accordance with this Section, or any such conversion or
extension is not permitted or required by this Section, then such Syndicated
Loans shall be automatically converted into Base Rate Loans at the end of their
respective Interest Periods.  The Agent shall give each Bank notice as promptly
as practicable of any such proposed conversion affecting any Syndicated Loans.

     3.4  Illegality, etc.  In the event any Bank shall determine (which
          ---------------                                               
determination shall be final and conclusive and binding on all the parties
hereto absent manifest error):

          (a)  Unavailability.  On any date for determining the appropriate
               --------------                                              
     Adjusted Eurodollar Rate for any Interest Period, that by reason of any
     changes arising on or after the date of this Loan Agreement affecting the
     London interbank Eurodollar market, dollar deposits in the principal amount
     requested are not generally available in the London interbank Eurodollar
     market, and fair means do not exist for ascertaining the applicable
     interest rate on the basis provided for in the definition of Adjusted
     Eurodollar Rate; then Eurodollar Loans will no longer be available, and
     requests for a Eurodollar Loan shall be deemed requests for Base Rate
     Loans, until such time as such Bank shall notify the Borrowers that the
     circumstances giving rise thereto no longer exist.

          (b)  Illegality.  At any time, that the making or continuance of any
               ----------                                                     
     Eurodollar Loan has become unlawful by compliance by such Bank in good
     faith with any law, governmental rule, regulation, guideline or order (or
     would conflict with any such governmental rule, regulation, guideline or
     order not having the force of law even

                                      29
<PAGE>
 
     though the failure to comply therewith would not be unlawful), or has
     become impractical as a result of a contingency occurring after the date of
     this Loan Agreement which materially and adversely affects the London
     interbank Eurodollar market; then Eurodollar Loans will no longer be
     available, requests for Eurodollar Loans shall be deemed requests for Base
     Rate Loans and the Borrowers may, and upon direction of the Bank, shall, as
     promptly as possible and, in any event within the time period required by
     law, have any such Eurodollar Loans then outstanding converted into Base
     Rate Loans.

     3.5  Increased Costs and Reduced Return.
          ---------------------------------- 

          (a)  If any Bank shall have determined that the adoption or
     implementation of, or any change in, any law, rule, treaty or regulation,
     or any policy, guideline or directive of, or any change in the
     interpretation or administration thereof by, any court, central bank or
     other administrative or governmental authority, or the compliance by any
     Bank or any lending office of any Bank with any directive of or guideline
     from any central bank or other governmental authority or the introduction
     of or change in any accounting principles applicable to any Bank or any
     lending office of any Bank (in each case, whether or not having the force
     of law), shall (i) change the basis of taxation of payments to any Bank or
     any lending office of any Bank of any amounts payable hereunder (except for
     taxes on the overall income of any Bank or any lending office of any Bank),
     (ii) impose, modify or deem applicable any reserve, special deposit or
     similar requirement against any Loan or Letter of Credit or against assets
     of or held by, or deposits with or for the account of, or credit extended
     by, any Bank or any lending office of any Bank, or (iii) impose on any Bank
     or any lending office of any Bank any other condition regarding this Loan
     Agreement, and the result of any event referred to in clauses (i), (ii) or
     (iii) above shall be to increase the cost to any Bank or any lending office
     of any Bank of making any Loan or participating in a Letter of Credit,
     maintaining its Commitment to make any Loan, or to reduce any amount
     received or receivable by any Bank hereunder, then, upon demand by such
     Bank, the Borrowers shall pay to such Bank such additional amounts as will
     compensate such Bank for such increased costs or reductions in amount,
     together with interest on such additional amounts calculated from the date
     such costs or reductions are incurred.

          (b)  If any Bank shall have determined that any Capital Guideline or
     adoption or implementation of, or any change in, any Capital Guideline by
     the governmental authority charged with the interpretation or
     administration thereof, or compliance by any Bank or any lending office of
     such Bank with any Capital Guideline or with any request or directive of
     any such governmental authority with respect to any Capital Guideline, or
     the implementation of, or any change in, any applicable accounting
     principles (in each case, whether or not having the force of law), either
     (i) affects or would affect the amount of capital required or expected to
     be maintained by any Bank or any lending office of such Bank, and such Bank
     determines that the amount of such capital is increased as a direct or
     indirect consequence of any Loans made or maintained or any Commitment to
     make Syndicated Loans, or such Bank's or such lending office's other
     obligations hereunder, or (ii) has or would have the effect of reducing the
     rate of return on such Lender's or such lending office's capital to a level
     below that which such Bank could have achieved but for such circumstances
     as a consequence of any Loans made or maintained, or the Commitment to make
     Syndicated Loans, such Bank's or such lending office's other obligations
     hereunder (in each case, taking into consideration 

                                      30
<PAGE>
 
     the Bank's or such lending office's policies with respect to capital
     adequacy), then, upon demand by such Bank, the Borrowers shall pay to such
     Bank from time to time such additional amounts as will compensate such Bank
     for such cost of maintaining such increased capital or such reduction in
     the rate of return on the such Bank's or such lending office's capital.

          (c)  Upon determining in good faith that any additional amounts will
     be payable pursuant to this Section, any Bank will give prompt written
     notice thereof to the Agent and the Borrowers, which notice shall set forth
     the basis of the calculation of such additional amounts and, if requested
     by the Borrowers, supporting documentation therefore, although the failure
     to give any such notice shall not release or diminish any of the Borrowers'
     obligations to pay additional amounts pursuant to this Section; provided,
                                                                     --------
     however, the Borrowers shall not be obligated to pay any of such amounts to
     -------
     any such Bank until it receives the applicable notice from such Bank
     together with any requested supporting documentation. Determination by any
     Bank of amounts owing under this Section shall, absent manifest error, be
     final and conclusive and binding on the parties hereto. Failure on the part
     of any Bank to demand compensation for any period hereunder shall not
     constitute a waiver of such Bank's rights to demand any such compensation
     in such period or in any other period.

          (d)  The Borrowers will reimburse the Letter of Credit Bank on demand
     for all charges and expenses made or incurred by the Letter of Credit Bank
     in connection with each Letter of Credit including any increased expense to
     the Letter of Credit Bank resulting from the application of any tax (other
     than income tax), reserve requirement or deposit insurance premiums; the
     amount of such charges and expenses to be determined by the Letter of
     Credit Bank in good faith.

          (e)  All amounts payable under this Section 3.5 shall bear interest
     from the date that is ten (10) Business Days after the date of demand by
     any Bank until payment in full to such Bank at a per annum rate equal to
     the Base Rate plus 2%.

     3.6  Compensation.  The Borrowers shall compensate each Bank, upon its
          ------------                                                     
written request (which request shall set forth the basis for requesting such
compensation), for all reasonable losses, expenses and liabilities (including,
without limitation, any loss, expense or liability incurred by reason of the
liquidation or reemployment of deposits or other funds required by such Bank to
fund its Eurodollar Loans) which such Bank may sustain:

          (a)  if for any reason (other than a default by such Bank or Agent) a
     borrowing of Eurodollar Loans does not occur on a date specified therefor
     in a Notice of Borrowing or Notice of Conversion;

          (b)  if any repayment or conversion of any Eurodollar Loan occurs on a
     date which is not the last day of an Interest Period applicable thereto;

          (c)  if any prepayment of any Eurodollar Loan is not made on any date
     specified in a notice of prepayment given by the Borrowers; or

          (d)  as a consequence of any other default by the Borrowers to repay
     their Loans or any Letter of Credit when required by the terms of this Loan
     Agreement.

                                      31
<PAGE>
 
Calculation of all amounts payable to a Bank under this Section shall be made as
though such Bank has actually funded its relevant Eurodollar Loan through the
purchase of a Eurodollar deposit bearing interest at the Eurodollar Rate, in an
amount equal to the amount of that Loan, having a maturity comparable to the
relevant Interest Period and in the case of Eurodollar Loans, through the
transfer of such Eurodollar deposit from an offshore office of that Bank to a
domestic office of that Bank in the United States of America; provided, however,
                                                              --------  ------- 
that each Bank may fund each of its Eurodollar Loans in any manner it sees fit
and the foregoing assumption shall be utilized only for the calculation of
amounts payable under this Section.

     3.7  Taxes.  (a)  All payments made by the Borrowers hereunder, under the
          -----                                                               
Notes or under any Loan Document will be made without setoff, counterclaim,
deduction or other defense.  All such payments shall be made free and clear of
and without deduction for any present or future income, franchise, sales, use,
excise, stamp or other taxes, levies, imposts, deductions, charges, fees,
withholdings, restrictions or conditions of any nature now or hereafter imposed,
levied, collected, withheld or assessed by any jurisdiction (whether pursuant to
United States Federal, state, local or foreign law) or by any political
subdivision or taxing authority thereof or therein, and all interest, penalties
or similar liabilities, excluding taxes on the overall income of a Bank or any
lending office of such Bank, (such nonexcluded taxes are hereinafter
collectively referred to as the "Taxes").  If the Borrowers shall be required by
law to deduct or to withhold any Taxes from or in respect of any amount payable
hereunder, (i) the amount so payable shall be increased to the extent necessary
so that after making all required deductions and withholdings (including Taxes
on amounts payable to the Banks pursuant to this sentence) the Banks receive an
amount equal to the sum they would have received had no such deductions or
withholdings been made, (ii) the Borrowers shall make such deductions or
withholdings, and (iii) the Borrowers shall pay the full amount deducted or
withheld to the relevant taxation authority in accordance with applicable law;
provided, however, if any Bank subsequently recovers any of such deductions or
- --------  -------                                                             
withholdings, such Bank shall promptly refund to the Borrowers the amount of
such deductions or withholdings.  Whenever any Taxes are payable by a Borrower,
as promptly as possible thereafter, the Borrowers shall send the Banks and the
Agent an official receipt showing payment.  In addition, the Borrowers agree to
pay any present or future taxes, charges or similar levies which arise from any
payment made hereunder or from the execution, delivery, performance, recordation
or filing of, or otherwise with respect to, this Loan Agreement, the Notes or
any other Loan Document (hereinafter referred to as "Other Taxes").

          (b)  The Borrowers will indemnify the Banks for the amount of Taxes
     or Other Taxes (including, without limitation, any Taxes or Other Taxes
     imposed by any jurisdiction on amounts payable under this Section 3.7) paid
     by any Bank and any liability (excluding penalties, interest and expenses
     for nonpayment, late payment or otherwise) whether or not such Taxes or
     Other Taxes were correctly or legally asserted. This indemnification shall
     be paid within 30 days from the date on which such Bank makes written
     demand; provided, however, the Borrowers shall have the right to contest
     any such Taxes before any appropriate administrative agency or court of
     competent jurisdiction so long as such Bank is not adversely affected by
     any such contest, as reasonably determined by such Bank.

          (c)  Each Bank which is a foreign person (i.e., a Person other than
     a United States Person for United States Federal income tax purposes)
     hereby agrees that:

                                      32
<PAGE>
 
                    (1)  it shall, no later than the Closing Date (or, in the
               case of a Bank which becomes a party hereto pursuant to Section
               10.3(b) hereof after the Closing Date, the date upon which such
               Bank becomes a party hereto) deliver to the Borrowers through the
               Agent:

                         (A)  two accurate and complete signed originals of Form
               4224, or

                         (B)  two accurate and complete signed originals of Form
               1001, in each case indicating that such Bank is on the date of
               delivery thereof entitled to receive payments of principal,
               interest and fees for the account of such lending office or
               offices under this Loan Agreement free from withholding of United
               States Federal income tax;

                    (2)  if at any time such Bank changes its lending office or
               offices or selects an additional lending office, it shall, at the
               same time or reasonably promptly thereafter, deliver to the
               Borrowers through the Agent in replacement for, or in addition
               to, the forms previously delivered by it hereunder;

                         (A)  if such changed or additional lending office is
               located in the United States, two accurate and complete signed
               originals of Form 4224, or

                         (B)  otherwise, two accurate and complete signed
               originals of Form 1001,

               in each case indicating that such Bank is on the date of delivery
               thereof entitled to receive payments of principal, interest and
               fees for the account of such changed or additional lending office
               under this Loan Agreement free from withholding of United States
               federal income tax; and

                    (3)  it shall, promptly upon the Borrower's reasonable
               request to that effect, deliver to the Borrowers such other forms
               or similar documentation as may be required from time to time by
               any applicable law, treaty, rule or regulation in order to
               establish such Bank's tax status for withholding purposes.

               (d)  If the Borrowers fail to perform their obligations under
          this Section 3.7, the Borrowers shall indemnify the Banks for any
          incremental taxes, interest or penalties that may become payable as a
          result of any such failure.

          3.8  Change of Lending Office.  Each Bank agrees that, upon the
               ------------------------ 
occurrence of any event giving rise to the operation of Section 3.4(a) or (b)
or 3.7, it will, if requested by the Borrowers, use reasonable efforts (subject
to overall policy considerations of such Bank) to designate another lending
office for any Loans affected by such event, provided that such designation is
                                             -------- 
made on such terms that such Bank and its lending office suffer no disadvantage
(including, without limitation, no economic, legal or regulatory disadvantage),
with the object of avoiding the consequence of the event giving rise to the
operation of any such Section. Nothing in this Section shall affect or postpone
any of the obligations of the Borrowers or the right of any Bank provided in
Sections 3.4, 3.5, or 3.7.

                                      33

     3.9  Late Payment Fee.  Should any principal installment payment be in
          ----------------                                                 
default for more than 15 days, and if no default rate of interest has yet been
imposed, then there may be imposed, to the extent permitted by law, a
delinquency charge not to exceed 2% of such installment in default.  In
addition, at the Majority Banks' option, any overdue interest, fees and charges
may, for purposes of computing and accruing interest, be deemed to be a part of
the corresponding principal Obligation and interest shall accrue on a daily
compounded basis after such date (at the applicable rate, including any default
rate under Section 3.1) thereon.

     3.10 Payments and Computations.  Except as otherwise specifically provided
          -------------------------                                            
herein, all payments hereunder shall be made to the Agent in U.S. dollars in
immediately available funds at its offices in Charlotte, North Carolina, not
later than 1:00 p.m. (Charlotte, North Carolina time) on the date when due.
Payments received after such time shall be deemed to have been received on the
next succeeding Business Day.  The Agent will thereafter cause to be distributed
promptly like funds relating to the payment of principal or interest or fees
ratably to the Banks entitled to receive such payments in accordance with the
terms of this Loan Agreement.  Whenever any payment hereunder shall be stated to
be due on a day which is not a Business Day, the due date thereof shall be
extended to the next succeeding Business Day (subject to accrual of interest and
fees for the period of such extension), except that in the case of Eurodollar
Loans, if the extension would cause the payment to be made in the next following
calendar month, then such payment shall instead be made on the next preceding
Business Day.  All computations of interest and fees shall be made on the basis
of actual number of days elapsed over a year of 360 days.  Interest shall accrue
from and include the date of such Loan, but exclude the date of payment.

     3.11 Replacement or Removal of Bank.  In the event that either:
          ------------------------------                            

          (a)  any Bank or Banks refuse to consent to certain proposed changes,
     waivers or discharges which have been approved by the Majority Banks as
     provided in Section 10.6, or

          (b)  any Bank or Banks refuse to consent to any extension to a
     Termination Date with respect to the 364 Day Facility which the Majority
     Banks have agreed to extend, or

          (c)  the Agent receives one or more notices claiming compensation
     reimbursement or indemnity (each, a "Compensation Notice") pursuant to the
     provisions of Sections 3.4, 3.5 or 3.7 and the aggregate amount of all such
     compensation, reimbursement or indemnity payments made or required to be
     made by the Borrowers to such Bank pursuant to Sections 3.4, 3.5 or 3.7 is
     materially greater (as determined by the Borrowers in their reasonable
     judgment) than the weighted average amount of payments made or required to
     be made to the other Banks pursuant to Sections 3.4, 3.5 or 3.7 and/or such
     Bank refuses or is unable to change lending offices pursuant to Section 3.8
     after a request from the Borrowers to do so,

then, so long as no Potential Default or Event of Default shall have occurred
- ----                                                                         
and be continuing, the Borrowers may, within 60 days after any such refusal or
receipt of any such Compensation Notice, elect to terminate such Bank as a party
to this Loan Agreement; provided, the Borrowers may elect to terminate such Bank
under subparagraphs (a) or (b) above only if, together with its notice of
termination, it provides to the Agent a commitment from another 

                                      34
<PAGE>
 
financial institution meeting the criteria of an Eligible Assignee and otherwise
reasonably satisfactory to the Agent (a "Replacement Bank") to replace the
Commitment of the terminated Bank under this Loan Agreement on the terms and
conditions set forth herein. Under subparagraph (c) above, if any Bank to be
terminated has a Commitment which, together with the amount of any Commitment(s)
concurrently therewith to be reduced, aggregates 20% or less of the aggregate
Commitments, the Borrowers may elect either to replace such Bank with another
Replacement Bank or to reduce the Commitment by the amount of the Commitment of
such Bank. Under subparagraph (c) above, if any Bank to be terminated has a
Commitment which, together with the amount of any Commitment or Commitments
concurrently therewith to be reduced in accordance with this Section 3.11,
aggregates in excess of 20% of the aggregate Commitments, the Borrowers may
elect to terminate such Bank only if, together with its notice of termination,
they provide to the Agent a Commitment from a Replacement Bank to replace the
Commitment of the terminated Bank under this Loan Agreement on the terms and
conditions set forth herein. The Borrowers' election to terminate a Bank under
this Section 3.11 shall be set forth in a written notice from the Borrowers to
the Agent (with a copy to such Bank), setting forth (i) the basis for
termination of such Bank, (ii) that the Borrowers intends to replace such Bank
with a Replacement Bank together with the name of such Replacement Bank, and
(iii) the date (not later than 30 days after the date of such notice) when such
termination shall become effective (the "Termination Effective Date"). On the
Termination Effective Date, (x) the Replacement Bank shall pay the terminated
Bank an amount equal to all principal, interest, fees and other amounts owed to
such Bank (including, without limitation, any amounts owed under Sections 3.4,
3.5 or 3.7), through the date on which such termination becomes effective, and
(y) there shall have been received by the Agent all documents and supporting
materials necessary, in the reasonable judgment of the Agent to evidence the
substitution of the Replacement Bank for such Bank.

entitled to be secured as long as any such other Indebtedness shall be so
secured; provided, that this covenant shall not

or more of the voting power of MCC's capital stock, or with any Affiliate of MCC
or of any such holder, on terms that are materially less favorable to such
Borrower or that Subsidiary, as the case may be, than those which would be
obtained at the time from Persons who are not such a holder or an Affiliate;
provided, that the foregoing restriction shall not apply to any transaction
- --------

Borrower to any other Borrower or Subsidiary (other than NSI); (iv) Indebtedness

     7.11    Subsidiary Formation; Restrictions on Subsidiary Dividends.  Except
             ----------------------------------------------------------         
for a Subsidiary formed directly in connection with an Acquisition as to which
the provisions of Section 7.6 will apply, no Borrower or Subsidiary will form
any other Subsidiary unless simultaneously therewith the newly formed Subsidiary
delivers to the Banks an unconditional guaranty of the Obligations in form and
substance satisfactory to the Majority Banks, together with an opinion of
counsel with respect to the enforceability of same acceptable to the Majority
Banks.  Neither MCC nor any other Borrower will permit any Subsidiary (including
any Borrower which is a Subsidiary) to enter into any agreement prohibiting or
restricting the 

                                      50

             -------------------------                                         
independent effect so that if a particular action or condition is not permitted
by any of such covenants, the fact that it would be permitted by an exception
to, or be otherwise within the limitations of, another covenant shall not avoid
the occurrence of an Event of Default or Potential Default if such action is
taken or condition exists.

direction of the Majority Banks, shall, by written notice to the Borrowers take

Letter of Credit Obligations shall immediately become due and payable without
the giving of any notice or other action by Agent or the Banks.

                               AGENCY PROVISIONS
                               -----------------

     9.1    Appointment.  Each Bank hereby irrevocably designates and appoints
            -----------
the Agent to act for it as specified herein and the other Loan Documents, and
each such Bank hereby irrevocably authorizes the Agent, as the Agent for such
Bank, to take such action on its behalf under the provisions of this Loan
Agreement and the other Loan Documents and to exercise such powers and perform
such duties as are expressly delegated to the Agent by the terms hereof and of
the other Loan Documents, together with such other powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary elsewhere
herein and in the other Loan Documents, the Agent shall not have any duties or
responsibilities except those expressly set forth herein and therein, or any
fiduciary relationship with any Bank, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Loan Agreement or any of the other Loan Documents, or shall otherwise exist
against the Agent. The provisions of this Article are solely for the benefit of
the Agent and the Banks and the Borrowers shall not have any rights as a third
party beneficiary of the provisions hereof. In performing its functions and
duties under this Loan Agreement and the other Loan Documents, the Agent shall
act solely as Agent of the Banks and does not assume and shall not be deemed to
have assumed any obligation or relationship of agency or trust with or for the
Borrowers.

     9.2    Delegation of Duties.  The Agent may execute any of its respective
            --------------------                                              
duties hereunder or under the other Loan Documents by or through Agent or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
legal matters pertaining to such duties.  The Agent shall not be responsible for
the negligence or misconduct of any agents or attorneys-in-fact selected by it
with reasonable care except to the extent otherwise required by Section 9.3.

     9.3    Exculpatory Provisions.  Neither the Agent nor any of its respective
            ----------------------                                              
officers, directors, employees, agents, attorneys-in-fact or affiliates shall be
(a) liable for any action lawfully taken or omitted to be taken by them or such
Person under or in connection herewith or in connection with any of the other
Loan Documents (except for their or such Person's own gross negligence or
willful misconduct), or (b) responsible in any manner to any of the Banks for
any recitals, statements, representations or warranties made by the Borrowers
contained herein or in any of the other Loan Documents or in any certificate,
report, statement or other document referred to or provided for in, or received
by Agent under or in connection herewith or in connection with the other Loan
Documents, or enforceability or sufficiency herefor of any of the other Loan
Documents, or for any failure of any of the Borrowers to perform their
obligations hereunder or thereunder.  The Agent shall not be responsible to any
Bank for the effectiveness, genuineness, validity, enforceability,
collectibility or sufficiency of this Loan Agreement or any of the other Loan
Documents or for any representations, warranties, recitals or statements made
herein or therein or made in any written or oral statement or in any financial
or other statements, instruments, reports, certificates or any other documents
in connection herewith or therewith furnished or made by or on behalf of any
Borrower to the Agent or any Bank or be required to ascertain or inquire as to
the performance or observance of any of the terms, conditions, provisions,
covenants or agreements contained herein or therein or as to the use of the
proceeds of the Loans or of the existence or possible existence of any Potential
Default or Event of Default or to inspect the properties, books or records of
the Borrowers.

     9.4    Reliance on Communications.  The Agent shall be entitled to rely,
            --------------------------
and shall be fully protected in relying, upon any note, writing, resolution,
notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy,
telex or teletype message, statement, order or 

                                      54
<PAGE>
 
other document or conversation believed by it to be genuine and correct and to
have been signed, sent or made by the proper Person or Persons and upon advice
and statements of legal counsel (including, without limitation, counsel to the
Borrower), independent accountants and other experts selected by such Agent. The
Agent may deem and treat the Banks as the owner of their respective interests
hereunder for all purposes unless a written notice of assignment, negotiation or
transfer thereof shall have been filed with such Agent in accordance with this
Loan Agreement. The Agent shall be fully justified in failing or refusing to
take any action under this Loan Agreement or under any of the other Loan
Documents unless it shall first receive such advice or concurrence of the
Majority Banks as it deems appropriate or it shall first be indemnified to its
satisfaction by the Banks against any and all liability and expense which may be
incurred by them by reason of taking or continuing to take any such action.
Except as expressly provided to the contrary herein, the Agent shall in all
cases be fully protected in acting, or in refraining from acting, hereunder or
under any of the other Loan Documents in accordance with a request of the
Majority Banks (or to the extent specifically provided in Section 10.6, with a
request of all the Banks) and such request and any action taken or failure to
act pursuant thereto shall be binding upon all the Banks (including their
successors and assigns).

     9.5    No Default.  The Agent shall not be deemed to have knowledge or
            ----------
notice of the occurrence of any Potential Default or Event of Default hereunder
unless the Agent has received notice from a Bank or the Borrowers referring to
the Loan Document, describing such Potential Default or Event of Default and
stating that such notice is a "notice of default." In the event that the Agent
receives such a notice, the Agent shall give prompt notice thereof to the Banks.
The Agent shall take such action with respect to such Potential Default or Event
of Default as shall be directed by the Majority Banks; provided that, unless and
                                                       --------
until the Agent shall have received such directions, the Agent may (but shall
not be obligated to) take such action, or refrain from taking such action, with
respect to such Potential Default or Event of Default as it shall deem advisable
in the best interests of the Banks.

     9.6    Non-Reliance on Agent and Other Banks.  Each Bank expressly
            -------------------------------------                      
acknowledges that neither the Agent nor any of its respective officers,
directors, employees, agents, attorneys-in-fact or affiliates has made any
representations or warranties to them and that no act by the Agent or any
respective affiliate thereof hereinafter taken, including any review of the
affairs of the Borrowers, shall be deemed to constitute any representation or
warranty by the Agent to any Bank.  Each Bank represents to the Agent that it
has, independently and without reliance upon the Agent or any other Bank, and
based on such documents and information as it has deemed appropriate, made its
own appraisal of and investigation into the business, assets, operations,
property, financial and other conditions, prospects and creditworthiness of the
Borrowers and made its own decision to make its Loans hereunder and enter into
this Loan Agreement.  Each Bank also represents that it will, independently and
without reliance upon the Agent or any other Bank, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit analysis, appraisals and decisions in taking or not taking action
under this Loan Agreement, and to make such investigation as it deems necessary
to inform itself as to the business, assets, operations, property, financial and
other conditions, prospects and creditworthiness of the Borrowers.  Except for
notices, reports and other documents expressly required to be furnished to the
Banks by the Agent hereunder, the Agent shall not have any duty or
responsibility to provide any Bank with any credit or other information
concerning the business, operations, assets, property, financial or other
conditions, prospects or creditworthiness of the Borrowers which may come into
the possession of the Agent or any of its respective officers, directors,
employees, agents, attorneys-in-fact or affiliates.

                                      55

     9.7    Indemnification.  The Banks agree to indemnify the Agent in its
            ---------------                                                
capacity as such on a pro rata basis based upon the Commitment Percentages of
the Banks from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, reasonable expenses or
disbursements of any kind whatsoever which may at any time (including without
limitation at any time following the payment of the Obligations) be imposed on,
incurred by or asserted against the Agent in its capacity as such in any way
relating to or arising out of this Loan Agreement or the other Loan Documents or
any documents contemplated by or referred to herein or therein or the
transactions contemplated hereby or thereby or any action taken or omitted by
the Agent under or in connection with any of the foregoing; provided that no
                                                            --------        
Bank shall be liable for the payment of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements to the extent paid by the Borrowers or to the extent
resulting from the Agent's gross negligence or willful misconduct.  If any
indemnity furnished to the Agent for any purpose shall, in the opinion of the
Agent be insufficient or become impaired, the Agent may call for additional
indemnity and cease, or not commence, to do the acts indemnified against until
such additional indemnity is furnished.  The agreements in this Section shall
survive the payment of the Obligations and all other amounts payable hereunder
and under the other Loan Documents.

     9.8    Agent in its Individual Capacity.  The Agent and its respective
            --------------------------------                               
affiliates may make loans to, accept deposits from and generally engage in any
kind of business with the Borrowers as though the Agent were not an Agent
hereunder.  With respect to the Loans made hereunder, the Agent shall have the
same rights and powers under this Loan Agreement as any Bank and may exercise
the same as though it were not an Agent, and the terms "Bank" and "Banks" shall
include the Agent in its individual capacity.

     9.9    Successor Agent.  Agent may, at any time, resign as Agent hereunder
            ---------------                                                    
upon 30 days written notice to the Banks, and be removed as an Agent hereunder
with or without cause by the Majority Banks upon 30 days written notice to such
Agent.  Upon any such resignation or removal, the Majority Banks shall have the
right to appoint a successor Agent with the consent of the Borrowers, so long as
the Borrowers are not in default.  If no successor Agent shall have been so
appointed by the Majority Banks, and shall have accepted such appointment,
within 30 days after the notice of resigning Agent's resignation or the Majority
Banks, notice of removal, then the retiring Agent shall select a successor Agent
provided such successor Agent is a commercial bank organized under the laws of
the United States of America or of any State thereof and has a combined capital
and surplus of at least $400,000,000.  Upon the acceptance of any appointment as
an Agent hereunder by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Agent, and the retiring Agent shall be discharged from its
duties and obligations as Agent under this Loan Agreement and the other Loan
Documents and the provisions of this Section shall inure to its benefit as to
any actions taken or omitted to be taken by it while it was Agent under this
Loan Agreement.

such rights, upon the occurrence of an Event of Default, each Bank is authorized
at any time and from time to time, without presentment, demand, protest or other
notice of any kind (all of which rights being hereby expressly waived), to set-
off and to appropriate and apply any and all deposits (general or special) and
any other indebtedness at any time held or owing by such Bank (including,
without limitation, branches, agencies or Affiliates of such Bank wherever
located) to or for the credit or the account of the Borrowers against
obligations and liabilities of the Borrowers to such Bank hereunder, under the
Notes, the other Loan Documents or otherwise, irrespective of whether such Bank
shall have made any demand hereunder and although such obligations, liabilities
or claims, or any of them, may be contingent or unmatured, and any such set-off
shall be deemed to have been made immediately upon the occurrence of an Event of
Default even though such charge is made or entered on the books of such Bank
subsequent thereto. The Borrowers hereby agree that any Person purchasing a
participation in the Loans and Commitments hereunder pursuant to Section 10.3(c)
may exercise all rights of set-off with respect to its participation interest as
fully as if such Person were a Bank hereunder.

Bank shall, in a reasonably prompt fashion after it has engaged in any material
discussions with an Eligible Assignee that may lead to an assignment referred to

Agreement, together with copies of the most recent Financial Statements and such
other agreements, documents, instruments, certificates and information as it has
deemed appropriate to make its own credit analysis and decision to enter into

reliance upon Agent, such assigning Bank or any other Bank and based on such
agreements, documents, instruments, certificates and information as it shall
deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Loan Agreement and the other Loan
Documents; (vi) such assignee appoints and authorizes the Agent to take such

all the obligations which by the terms of this Loan Agreement and the other Loan

and Banks may treat each Person whose name is recorded in the Register pursuant
to the terms hereof as a Bank hereunder for all purposes of this Loan Agreement.
The Register shall be available for inspection by Borrowers, Subsidiaries and
Banks at any reasonable time and from time to time upon reasonable prior notice.

            (e)   Upon its receipt of an Assignment and Acceptance executed by
an assigning Bank and an Eligible Assignee and the required processing and
recordation fee, Agent shall, if such Assignment and Acceptance is duly
completed and is in the required form, (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the 

                                      58

of its Loans and Commitments, a new Note or Notes payable to the order of such
assignor in the appropriate principal amount(s) evidencing such assignor's Loans
and Commitments retained by it. Such new Note(s) shall be dated the date of the
surrendered Note(s) which they replace and shall otherwise be in substantially
the form of the surrendered Notes, as appropriate.

(not to be unreasonably withheld) and the Agent, sell participations to one or
more banks in all or a portion of its interests, rights and obligations under
this Loan Agreement (including all or a portion of its Loans or Commitments)
held by it; provided, however, that (i) such Bank shall remain a Bank for all

not constitute a Bank under this Loan Agreement, (ii) such Bank's obligations
under this Loan Agreement shall remain unchanged, (iii) such Bank shall remain
solely responsible to the other parties hereto for the performance of such
obligations, (iv) the participating banks or other entities shall be entitled to

extent as if they were Banks, except that no such participant shall be entitled
to receive any greater benefit pursuant to such Sections than its assignor Bank
would have been entitled to receive with respect to the rights participated, and
(v) Borrowers, Subsidiaries, Agent and the other Banks shall continue to deal
solely and directly with such Bank in connection with such Bank's interests,
rights and obligations under this Loan Agreement, and such Bank shall retain the
sole right to enforce the obligations of Borrowers and its Subsidiaries relating
to the Loans and to approve any amendment, modification or waiver of any
provision of this Loan Agreement, provided that such participation agreement may
                                  -------- ----
provide that such Bank will not agree to any amendment, modification or waiver
of this Loan Agreement or the other Loan Documents, without the consent of such
participant, that would (A) reduce the principal or the rate of interest payable
by Borrowers on any Loan or reduce any fees payable by Borrowers, (B) postpone
any date fixed for the payment of principal of or interest on the Loans or any
fees payable by Borrowers, (C) increase any Commitment of any Bank or subject
any Bank to any obligation to make Loans, or (D) amend Section 10.3 or any other

participation or proposed assignment or participation pursuant to this Section
10.3, disclose to the assignee or participant or proposed assignee or
participant any information relating to Borrowers or any Subsidiary on the Loan
Documents furnished to such Bank by or on behalf of the Borrowers or any
Subsidiary; provided, however, that, prior to any such disclosure, each such
            --------  -------
assignee or participant or proposed assignee or participant shall execute an
agreement whereby such assignee or participant shall agree (subject to customary
exceptions) to preserve the confidentiality of any non-public information
received from such Bank.

            (h)   Notwithstanding anything to the contrary contained in this
Section 10.3, any Bank may at any time or from time to time assign all or any
portion of its rights under this Loan Agreement with respect to its Loans,
Commitments and Notes to a Federal Reserve Bank. No such assignment shall
release the assigning Bank from its obligations under this Loan Agreement.

remedies provided herein are cumulative and not exclusive of any rights or
remedies which the Agent or any Bank would otherwise have.  No notice to or

effect and shall be construed without giving effect to the illegal, invalid or

     10.13  Entirety.  This Loan Agreement together with the other Loan
            --------

cash without recourse or warranty from the other Banks an interest in the
obligations of the Borrowers to such Banks in such amount as will result in a
proportional participation by all of the Banks in such amount, provided that if
                                                               --------

     costs, expenses and disbursements of any kind or nature whatsoever
     (including, 

                                      62
<PAGE>
 
     without limitation, the reasonable fees and disbursements of counsel for
     such Indemnitees in connection with any investigative, administrative or
     judicial proceeding, whether or not such Indemnitee shall be designated a
     party thereto), which may be imposed on, incurred by, or asserted against
     such Indemnitee by any Person, in any manner relating to or arising out of
     or pursuant to this Loan Agreement or by reason of any action taken by any
     of them in good faith in furtherance of the provisions of this Loan
     Agreement (the "Indemnified Liabilities"); provided, that the Borrowers
                                                --------
     shall have no obligation hereunder with respect to Indemnified Liabilities
     arising from (i) the gross negligence or willful misconduct of any such
     Indemnitee; (ii) any action between a Borrower and one or more Indemnitees
     in which such Borrower is the prevailing party; or (iii) any action between
     any Bank and assignee or participant of that Bank with respect to the
     matters contemplated by Section 10.3 hereof.

            (b)   Without limiting the generality of Section 10.16(a) hereof,
     the Borrowers unconditionally agree to forever indemnify, defend and hold
     harmless, and covenant not to sue for any claim for contribution against,
     the Banks and the Agent for any damages, costs, loss or expense, including
     without limitation, response, remedial or removal costs, arising out of any
     of the following: (i) any presence, release, threatened release or disposal
     of any hazardous or toxic substance or petroleum by any Borrower or
     otherwise occurring on or with respect to its property, (ii) the operation
     or violation of any environmental law, whether federal, state, or local,
     and any regulations promulgated thereunder, by any Borrower or otherwise
     occurring on or with respect to its property, (iii) any claim for personal
     injury or property damage in connection with any Borrower or otherwise
     occurring on or with respect to its property, and (iv) the inaccuracy or
     breach of any environmental representation, warranty or covenant by any
     Borrower made herein or in any loan agreement, promissory note, or any
     other instrument or document evidencing or securing any indebtedness,
     obligations or liabilities of any Borrower owing to the Banks or setting
     forth terms and conditions applicable thereto or otherwise relating
     thereto, except for damages arising from a Bank's willful misconduct or
     gross negligence. This indemnification shall survive the payment and
     satisfaction of all indebtedness, obligations and liabilities of the
     Borrowers owing to the Banks and the termination of this Loan Agreement,
     and shall remain in force beyond the expiration of any applicable statute
     of limitations and payment or satisfaction in full of any single claim
     under this indemnification. This indemnification shall be binding upon the
     successors and assigns of each Borrower and shall inure to the benefit of
     Banks, the Agent, and their directors, officers, employees, agents, and
     collateral trustees, and their successors and assigns.

            (c)   As soon as is practicable after receipt by an Indemnitee of
     notice of the making of any claim, the service of any complaint or the
     commencement of any action or proceeding (collectively, a "Claim") by any
     Person other than the Borrowers with respect to which indemnification is
     sought hereunder, the Indemnitees will notify the Borrowers in writing of
     such Claim, naming the counsel such Indemnitee proposes to use to defend
     against such Claim (but failure to so notify the Borrowers will not relieve
     the Borrowers from any liability which they may have hereunder or
     otherwise, except to the extent that such failure materially prejudices the
     Borrowers' rights). The Borrowers shall have the right to approve the
     counsel proposed to be used by such Indemnitee in the defense of such
     Claim, but such approval shall not be unreasonably delayed. Such counsel
     shall consist of a single firm for all Indemnitees unless counsel to any
     Indemnitee shall advise it in writing that a conflict of interest exists
     between it and one or more other Indemnitees in conducting the defense of
     such Claim that would make advisable or prudent the retaining of separate
     counsel for the defense of such Claim, in 

                                      63
<PAGE>
 
     which case an additional firm may be retained on behalf of each such
     Indemnitee so advised. The Borrowers shall also have the right to approve
     any proposed settlement of any such Claim, but such approval shall not be
     unreasonably withheld or delayed.

     10.17  Change in Accounting Principles.  If any change in accounting
            -------------------------------                              
principles from those used in the preparation of the Financial Statements
referred to in Subsection 5.3.1 is hereafter occasioned by the promulgation of
rules, regulations, pronouncements and opinions by or required by the Financial
Accounting Standards Board or the American Institute of Certified Public
Accountants or the Securities and Exchange Commission (or successors thereto or
agencies with similar functions) and results in a change in the method of
calculation of financial covenants, standards or terms found in Articles I, VI
and VII hereof, the parties hereto agree to enter into negotiations in order to
amend such provisions so as equitably to reflect such changes with the desired
result that the criteria for evaluating the Borrowers' financial condition shall
be the same after such changes in accounting principles as if such changes in
accounting principles had not been made.  Until such negotiations are completed
to the satisfaction of the Banks and the Borrowers and this Agreement amended to
reflect the results of such negotiations, such changes in accounting principles
shall not become effective for purposes of determining compliance with this
Agreement.

                                      64

     IN WITNESS WHEREOF, each of the parties hereto has caused a counterpart of
this Loan Agreement to be duly executed and delivered as of the date first above
written.
