Note II, and (d) all other fees, expenses and other similar amounts due under

occurred and be continuing, then the portion of the Remaining MTS Debt which
remains unpaid, together with all accrued but unpaid interest thereon, shall be
deemed satisfied on and as of September 1, 2006.  Upon the satisfaction of the
Remaining MTS Debt in the manner set forth above, the Borrowers shall have no
further Obligations to the Lender hereunder, except as expressly provided in
Sections 2.4(E)(iii) and 8.3 hereof.

         2.5     PLAN NOTE II.  At the Closing, the Borrowers shall execute and
deliver Plan Note II to the Lender to evidence the Borrowers' obligations to
repay a portion of the Original SouthTrust Indebtedness equal to $1,000,000.00.

                 (A)      Payment Terms.  Plan Note II shall be in the original
principal amount of $1,000,000.00, shall accrue interest at the Accrual Rate
(subject to forgiveness in certain events as set forth in Sections 2.5(E) and
2.6(A) hereof), and shall be paid as follows:

                          (i)     At the Closing, the Borrowers shall pay to 
         the Lender the sum of $250,000.00; and

                          (ii)    Borrowers shall pay to the Lender the sum of
         $500,000.00, (a) within seven (7) Business Days after receipt by any

         to the 1996 tax year and any prior tax year, or (b) on the Closing
         Date, if such refunds are received by the Borrowers prior to the
         Closing Date; and





                                       23
<PAGE>   28

                          (iii)   On the fifteenth (15th) day of March, 1997,
         and on the fifteenth (15th) day of each calendar month thereafter
         through and including March 15, 2002, the Borrowers shall pay to the
         Lender an amount equal to fifteen percent (15%) of the Excess Cash
         Flow for the calendar month immediately preceding the date of payment.

                 (B)      Discounted Pay-Off in Certain Events.
Notwithstanding the provisions of Section 2.5(A), if, on or prior to March 15,
1997, the payments theretofore received by the Lender under Plan Note II
aggregate $750,000.00, then, provided that no Major Default shall then have
occurred and be continuing under Plan Note II, under Plan Note I, under this
Agreement or under any of the Security Documents, the Borrowers shall not be
obligated to make any further payments under Plan Note II, and Plan Note II
shall be deemed fully satisfied, on and as of March 15, 1997 or, if earlier,
the date on which payments received by the Lender under Plan Note II aggregate
$750,000.00.

                 (C)      Satisfaction of Plan Note II Prior to Maturity Date
in Certain Events.  If the requirements of Section 2.5(B) are not satisfied,
but at any time prior to March 15, 2002, the payments theretofore received by
the Lender under Plan Note II aggregate $1,000,000.00, then, provided that no
Major Default shall then have occurred and be continuing under the Plan Notes,
under this Agreement or under any of the Security Documents, or under the
Plans, the Borrowers shall not be obligated to make any further payments under
Plan Note II, and Plan Note II shall be deemed fully satisfied, on and as of
the date on which the payments received by the Lender under Plan Note II
aggregate $1,000,000.00.

                 (D)      Optional Prepayment.  The Borrowers shall have the
right, at their option, without  premium or penalty, to prepay Plan Note II, in
whole but not in part, at any time; provided, that (i) at the time of any such
prepayment no default or Event of Default under this Agreement, under the Plan
Notes or under any of the Security Documents, or under the Plans, shall have
occurred and be continuing, and (ii) the Lender shall have received at least
thirty (30) days' prior written notice of each such prepayment.  Partial
prepayments shall not be permitted under Plan Note II, except that the
Borrowers may make partial prepayments of principal during the six (6) month
period ending on March 15, 1997, and if, as of March 15, 1997, the payments and
prepayments made by the Borrowers hereunder aggregate $750,000.00, such
payments will have the effect set forth in Section 2.5(B) hereof.

                 (E)      Satisfaction of Plan Note II on Maturity Date.  If
(i) all payments described in Section 2.5(A) are timely made and (ii) after
payment of the monthly installment of principal due on March 15, 2002, any
portion of the principal amount of Plan Note II remains unpaid, then, provided
that no Major Default shall have occurred and be continuing under the Plan
Notes, under this Agreement or under any of the Security Documents, then all
remaining principal, together with all accrued and unpaid interest under Plan
Note II, shall be deemed fully paid, and Plan Note II shall be deemed
satisfied, on and as of March 15, 2002.

         2.6     ADDITIONAL TERMS OF PLAN NOTES.

                 (A)      Interest at the Accrual Rate.  The Stated Principal
Amount of Plan Note I and the outstanding principal amount of Plan Note II
shall bear interest at the Accrual Rate, from the Petition Date until paid or
deemed satisfied in accordance with the terms of the Plan Notes and applicable
provisions of this Agreement.  If, however, the provisions of Sections 2.4 and
2.5 of this Agreement are fully and timely complied with, and provided that no
Major Default shall have occurred and be continuing under the Plan Notes, under
this Agreement or under any of the Security Documents, then the amount
representing the difference between (i) accrued interest on the Stated
Principal Amount of Plan Note I and the outstanding principal amount of Plan
Note II, at the Accrual Rate, and (ii) accrued interest on the Amortization
Principal Amount at the Pay Rate (or the Default Rate, as applicable) which has
been paid by the Borrowers hereunder and under the Plan Notes, shall be
forgiven on and as of the date or dates on which the then remaining Stated
Principal Amount of Plan Note I and the outstanding principal amount of Plan
Note II, as the case may be, are deemed satisfied in accordance with Sections
2.4 and 2.5 of this Agreement.

                 (B)      Calculation of Interest.  Interest with respect to
the Plan Notes shall be calculated and payable in the manner set forth in Plan
Note I and Plan Note II, respectively.

                 (C)      Default Rate.  At the option of the Lender, if any
installment of interest or principal under Plan Note I, or any payment of
principal under Plan Note II shall not be made as the same becomes due and
payable, interest shall be payable on the principal portion of such defaulted
payment and, to the extent permitted by law, on the interest portion of such
defaulted payment (if any), at the Default Rate, and, if any payment of
principal or interest shall not be made on the date on which any such payment
becomes due, interest shall be payable on the whole of the principal balance
then outstanding of the Stated Principal Amount under Plan Note I, or the then
outstanding balance of Plan Note II, as the case may be, at the Default Rate
for the subsequent duration of such default, whether or not acceleration has
occurred in accordance with Article VII hereof.

                 (D)      If, at any time, the Accrual Rate, the Pay Rate or
the Default Rate shall be deemed by any competent court of law, governmental
agency or tribunal to exceed the maximum rate of interest permitted by any
applicable Laws, then, for such time as such rates would be deemed excessive,
its application shall be suspended and there shall be charged instead the
maximum rate of interest permissible under such Laws, and any excess interest
or charges actually collected by the Lender shall be credited as a partial
prepayment of principal.

         2.7     PAYMENT TO THE LENDER.  All sums payable to the Lender
hereunder shall be paid directly to the Lender in United States Dollars and
immediately available funds at the place payment is due.  If the Lender shall
send the Borrowers statements of amounts due hereunder, such statements shall
be considered correct and conclusively binding on the Borrowers unless the
Borrowers notify the Lender to the contrary within thirty (30) days of their
receipt of any statement which they deem to be incorrect.  Alternatively, at
its sole discretion, the Lender may charge against any deposit account of any
of the Borrowers all or any part of any amount due hereunder.

ARTICLE 4.       COLLATERAL SECURITY

         4.1     COMPOSITION OF THE COLLATERAL; SECURITY INTERESTS GRANTED
PURSUANT TO ORIGINAL SOUTHTRUST LOAN DOCUMENTS.  The property in which a
security interest is granted or acknowledged pursuant to the provisions of
Section and  hereof or pursuant to the provisions of any Security Document is
herein collectively called the "Collateral."  The Collateral, together with all
of the Borrowers' other property of any kind held by the Lender, shall stand as
one general, continuing collateral security for all Obligations and, except as
expressly provided in Section 4.8 hereof, may be retained by the Lender until
all Obligations have been satisfied in full.  Each of the Borrowers hereby
acknowledges that, pursuant to the Original SouthTrust Loan Documents, each of
the Borrowers granted to the Lender valid, first priority security interests
and liens on all of the Collateral owned by them (or in which any of them has
any interest) as security for the Indebtedness and obligations evidenced by the
Original SouthTrust Loan Documents.  Each of the Borrowers hereby ratifies and
confirms the grant of such security interests and liens in favor of the Lender,
as security for all the Obligations.  Each of the Borrowers hereby agrees that
the provisions of Sections 4.2 and 4.3 hereof, in addition to providing for the
present grant of security interests and liens in the Collateral to secure the
full and prompt payment and performance of all Obligations, shall be construed
as (A) a ratification and restatement of their respective grants of security
interests and liens under and pursuant to the Original SouthTrust Loan 
Documents as security for the Obligations, and (B) a representation and 
warranty by Borrowers that all such security interests and liens remain in full
force and effect as of the Closing Date.

         4.2.    RIGHTS IN PROPERTY HELD BY THE LENDER.  As security for the
prompt satisfaction of all Obligations, each of the Borrowers hereby assigns,
transfers and sets over to the Lender all of the Borrowers' right, title and
interest in and to, and grants the Lender a lien on and a security interest in,
all amounts that may be owing from time to time by the Lender to the Borrowers
in any capacity, including, but without limitation, any balance or share
belonging to the Borrowers (or any of them) of any deposit or other account
with the Lender, which lien and security interest shall be independent of any
right of set-off which the Lender may have.

         4.3.    RIGHTS IN PROPERTY HELD BY ANY OF THE BORROWERS OR BY THE
LENDER.  As further security for the prompt satisfaction of all Obligations, in
addition to any other or further security provided under any of the Security
Documents, each of the Borrowers hereby assigns and transfers to the Lender all
of its right, title and interest in and to, and grants the Lender a lien upon
and security interest in, all of the following property and rights of such
Borrower, wherever located, whether now owned or hereafter acquired, together
with all replacements therefor and proceeds (including, but without limitation,

                                           thereof) in form satisfactory to the
                                           Lender as the Lender may, from time
                                           to time, specify;

                          4.5.1.2.         Pay, or reimburse the Lender for
                                           paying, all costs and taxes of

                                           Lender after the Lender determines
                                           in good faith that such filing or
                                           recording is necessary or desirable
                                           to perfect the Lender's security
                                           interest in the Collateral; and

                          4.5.1.3.         Take such other steps as the Lender
                                           may, from time to time, direct,
                                           including the noting of the Lender's
                                           lien on the Collateral and on any
                                           certificates of title therefor, all
                                           to perfect the Lender's security
                                           interest in the Collateral.

                 4.5.2.   In addition to the foregoing, and not in limitation
thereof:

                          4.5.2.1.         A carbon, photographic, or other

                                           be sufficient as a financing
                                           statement and may be filed in any
                                           appropriate office in lieu thereof;
                                           and

                          4.5.2.2.         To the extent lawful, the Borrowers
                                           hereby appoint the Lender as their
                                           respective attorney-in-fact (without
                                           requiring the Lender to act as such)
                                           to execute any financing statement
                                           in the name of any of the Borrowers,
                                           and to perform all other acts that
                                           the Lender deems appropriate to
                                           perfect and continue its security
                                           interest in, and to protect and
                                           preserve, the Collateral in
                                           accordance with the provisions of
                                           this Agreement.

         4.6.    LIEN WAIVERS.  Each of the Borrowers will use its best efforts
to cause each landlord of  all premises leased by such Borrower, and any
warehouseman or other bailee on whose premises any of the Collateral may be
located, to execute and deliver to the Lender instruments, in form and
substance satisfactory to the Lender, by which such mortgagee, landlord,
warehouseman, or bailee waives his or its rights, if any, in and to all Goods
composing a part of the Collateral.

         4.7.    CHATTEL PAPER OR INSTRUMENTS.  Each of the Borrowers will
deliver immediately to the Lender any Chattel Paper or Instruments arising out
of the Collateral usually, but not exclusively, as proceeds.  Further, the
parties hereby agree that such Chattel Paper or Instruments constitute original
Collateral rather than proceeds; but if proceeds, the Lender's security
interest created by this Agreement in the Chattel Paper or Instruments shall
not be claimed merely as proceeds.

of the Obligations.  In no event shall the Lender's release of its interest in
any Collateral, under this Section 4.8 or otherwise, constitute or be deemed to
constitute a waiver, release or modification of the Obligations of the
Borrowers hereunder or under the Plan Notes or of the obligations of the
Guarantor under the Guaranty, nor shall any such release of Collateral impair

Borrowers (or any of them)  contained herein or in any certificate or other

statement of material fact or omits to state a material fact necessary to make

material lease, contract, or other commitment thereof and no event has occurred
which, but for the giving of notice or the passage of time, or both, would
constitute a default;

used or employed in its business and products, each of which is listed on
EXHIBIT DD hereto and copies of which have been delivered to Lender; and

                 5.1.23.          Except as otherwise described on EXHIBIT EE

agreement relating to patents, trademarks or copyrights which could directly or
indirectly preclude or render impracticable the realization by the Lender of

remain no outstanding commitments hereunder.

Lender. Such policies shall contain a provision whereby they cannot be canceled
except after ten (10) days' written notice to the Lender.  Each of the
Borrowers will furnish to the Lender such evidence of insurance as the Lender
may require.  Each of the Borrowers hereby agrees that, in the event it fails

assigns to the Lender any returned or unearned premiums that may be due such
Borrower upon cancellation of any such policies for any reason whatsoever and
directs the insurers to pay the Lender any amounts so due at any time when an
Event of Default shall have occurred and be continuing.  The Lender is hereby
appointed the Borrowers' attorney-in-fact (without requiring the Lender to act
as such) to, from and after the occurrence and during the continuation of any
Event of Default, endorse any check which may be payable to any of the
Borrowers to collect such returned or unearned premiums or the proceeds of such
insurance, and any amount so collected may be applied by the Lender toward

paid when due, all taxes, water rates, assessments (including assessments for

property or which it is required to withhold and pay over, except that the
Borrowers shall be entitled to, in good faith and at their own expense,
diligently contest the same or the validity thereof by and in accordance with
appropriate legal proceedings, so long as such proceedings shall operate to
prevent (a) the collection of such taxes or levy upon and sale or forfeiture of
the subject property to satisfy such taxes or assessments and (b) the





                                       41

enforcement of such taxes or assessments against the Borrowers, or any of them,

therefor.

                 6.1.6.           Each of the Borrowers will take all necessary
steps to preserve its corporate existence and franchises and comply with all
present and future Laws applicable to it in the operation of its business, and
all material agreements to which it is subject.

                 6.1.7.           Each of the Borrowers will collect its

sound business practices.

                 6.1.9.           Each of the Borrowers will give immediate
notice to the Lender of: (1) any litigation proceeding in which it is a party
if an adverse decision therein would require it to pay over more than
$50,000.00 or deliver assets the value of which exceeds such sum (whether or
not the claim is considered to be covered by insurance); and (2) the
institution of any other suit or proceeding involving it that might materially
and adversely affect its operations, financial condition, property or business
prospects.

                 6.1.10.          Within ten (10) days of the Lender's request
therefor, each of the Borrowers will furnish the Lender with copies of federal
income tax returns filed by the Borrowers.

                 6.1.11.          Except when the amount thereof is being
contested in good faith by appropriate proceedings and with adequate reserves
therefor being set aside on the books of the Borrowers, each of the Borrowers
will pay when due (or within applicable grace periods) all Indebtedness, other
than ordinary trade debt, owed to third Persons and, with respect to
Indebtedness which constitutes ordinary trade debt, each of the Borrowers will
pay such Indebtedness within sixty (60) days of its due date.  If default be
made by any of the Borrowers in the payment of any principal (or installment
thereof) of, or interest on, any such Indebtedness, the Lender shall have the
right, in its sole and absolute discretion (but shall have no obligation), to
pay such interest or principal for the account of such Borrower and be
reimbursed by the Borrowers therefor.

                 6.1.12.          Each of the Borrowers will notify the Lender
immediately if it becomes aware of the occurrence of any Event of Default or of
any fact, condition or event that only with the giving of notice or passage of

material adverse change in the business prospects, financial condition
(including, without limitation, proceedings in bankruptcy, insolvency,
reorganization, or the

                                           such Indebtedness and such failure is
                                           based upon Lender's good faith

                                           otherwise prejudice the Lender's
                                           remaining rights hereunder, then the
                                           Lender's failure to grant such
                                           consent will not be, and will not be
                                           deemed to be, unreasonable; and

         obligations remain legally enforceable against such estate; or

                          (12)    A criminal investigation is commenced, in

         7.2.    ACCELERATION.

                 (A)      Automatic Acceleration.  Immediately and without
notice upon the occurrence of an Event of Default specified in Sections
7.1(A)(6), (A)(7) or (B)(6), all Obligations, whether arising hereunder, under
the Plan Notes or otherwise, shall immediately become due and payable without
further action of any kind on the part of the Lender, and the Lender may
exercise any rights or remedies available under this Agreement, the Security
Documents, at law or in equity.

                 (B)      Acceleration at the Option of the Lender. Upon the
occurrence of any Event of Default specified in Section 7.1 hereof, other than
Section 7.1(A)(6), (A)(7) or (B)(6), then at any time thereafter if any such
Event of Default shall then be continuing, the Lender may (1) declare all
Obligations (whether arising hereunder, under the Plan Notes or otherwise) to
be, whereupon the same shall become, immediately due and payable without
presentment, demand, protest or other notice of any kind, all of which are
hereby waived by the Borrowers, and (2) exercise any other rights or remedies
available under this Agreement, the Security Documents, at law or in equity.

                 (C)      Borrowers' Right to Obtain a Waiver of Events of
Default Other Than Major Defaults.  Upon the occurrence of any Event of Default
other than a Major Default, then, whether or not maturity of the Obligations
has been accelerated pursuant to Section 7.2(A) or (B), and whether or not the
Lender has commenced exercise of any of its rights or remedies hereunder, at
law or in equity, the Borrowers shall be entitled to obtain a waiver of such
Event of Default, but only in the manner, and within the time period, expressly
provided in this Section 7.2(C).  In order to obtain such a waiver, within
thirty (30) days after notice of the occurrence of such Event of Default from
the Lender, the Borrowers shall pay to the Lender an amount, in cash or other
immediately available funds, equal to the sum of:

                          (a) All of the then outstanding Amortization
                 Principal Amount under Plan Note I, together with all accrued
                 interest thereon at the Pay Rate (or the Default Rate, if
                 applicable),





                                       52
<PAGE>   57

                          (b) All amounts then outstanding (if any) under Plan
                 Note II, together with accrued interest thereon at the Default
                 Rate, if applicable, and

                          (c) All of the Lender's costs incurred as a result of
                 each such Event of Default, including, but without limitation,
                 all costs of acceleration of the Obligations, all fees and
                 expenses of counsel incurred in connection with the
                 enforcement of the Obligations, and all other costs and
                 expenses incurred in connection with the Lender's exercise of
                 any rights and remedies as a result of such Event of Default.

If, and only if, the amounts described in clauses (a), (b) and (c) above are
irrevocably paid to the Lender within the time period specified above, each
Event of Default (other than a Major Default) which exists at the time of such
payment shall be deemed to have been waived by the Lender, effective on the
date of such irrevocable payment; provided, that such waiver shall not extend
to any other Event of Default, or to the occurrence of any Event of Default
which may occur after any such payment.  Nothing contained in this Section
7.2(C) shall, or shall be deemed to, prevent or delay the exercise by the
Lender of any of its rights and remedies under this Agreement or the Security
Documents, at law or in equity, upon the occurrence of any Event of Default.
Notwithstanding any provision to the contrary contained in this Section 7.2(C),
the Borrowers' right to obtain a waiver of Events of Default (other than Major
Defaults) pursuant to this Section 7.2(C) shall automatically and immediately
expire upon the occurrence of any Major Default.

         7.3.    REMEDIES.

                 7.3.1.   Exercise of Remedies Generally.  After the occurrence
of any Event of Default under Section 7.1 or any acceleration under Section ,
the Lender shall have, in addition to the rights and remedies given it by this
Agreement and the Security Documents, all those allowed by all applicable Laws,
including, but without limitation, the Uniform Commercial Code as enacted in
any jurisdiction in which any Collateral may be located.  Without limiting the
generality of the foregoing, the Lender may immediately, without demand of
performance and without other notice (except as specifically required by this
Agreement or the Security Documents, or as required by Law and which cannot be
waived) or demand whatsoever to the Borrowers, all of which are hereby
expressly waived, and without advertisement, sell at public or private sale or
otherwise realize upon, in Birmingham, Alabama, or elsewhere, the whole or,
from time to time, any part of the Collateral, or any interest which the
Borrowers may have therein.  After deducting from the proceeds of sale or other
disposition of the Collateral all expenses (including all reasonable expenses
for legal services), the Lender shall apply such proceeds toward the
satisfaction of the Obligations which are then due, whether by acceleration
pursuant to Section  or otherwise, in such order as the Lender may elect.  Any
remainder of the proceeds after satisfaction in full of the Obligations shall
be distributed as required by applicable Laws.  Notice of any sale or other
disposition shall be given to the Borrowers at least five (5) days before the
time of any intended public sale or of the time after which any intended
private sale or other disposition of the Collateral is to be made, which the
Borrowers hereby agree shall be reasonable





                                       53
<PAGE>   58

notice of such sale or other disposition.  The Borrowers shall be liable for
any deficiency, jointly and severally.  The Borrowers agree to assemble, or to
cause to be assembled, at its own expense, the Collateral at such place or
places as the Lender shall designate.  At any such sale or other disposition,
the Lender may, to the extent permissible under applicable Laws, purchase the
whole or any part of the Collateral, free from any right of redemption on the
part of any of the Borrowers, which right is hereby waived and released.
Without limiting the generality of any of the rights and remedies conferred
upon the  Lender under this paragraph, the Lender may, to the full extent
permitted by applicable Laws:

                          7.3.1.1.         Enter upon the premises of any of
                                           the Borrowers, exclude therefrom the
                                           Borrowers or any Affiliate thereof,
                                           and take immediate possession of the
                                           Collateral, either personally or by
                                           means of a receiver appointed by a
                                           court of competent jurisdiction,
                                           using all necessary force to do so;

                          7.3.1.2.         At the Lender's option, use, operate,
                                           manage and control the Collateral in
                                           any lawful manner;

                          7.3.1.3.         Collect and receive all rents,
                                           income, revenue, earnings, issues
                                           and profits therefrom; and

                          7.3.1.4.         Maintain, repair, renovate, alter or
                                           remove the Collateral as the Lender
                                           may determine in its discretion.

                 7.3.2.   Agreement to Delay Exercising Certain Remedies in
Certain Events.  Notwithstanding the provisions of Section 7.3(A) hereof, the
Lender hereby agrees that, if an Event of Default, which does not constitute a
Major Default, occurs hereunder, then during the time period specified in
Section 7.2(C), the Lender will not (i) actually take possession or control of
any Collateral, (ii) dispose of any Collateral, (iii) direct the Borrowers'
Account debtors to make payments directly to the Lender, or (iv) exercise any
right of setoff with respect to any funds of Borrowers on deposit with the
Lender.  Nothing contained in this Section 7.3(B) shall, or shall be deemed to,
prevent or delay the Lender from commencing any action leading to the taking of
any actions described in items (i) through (iv), above, or from exercising any
of its other available rights or remedies, as a result of the occurrence of an
Event of Default, including, without limitation, the commencement of litigation
on the Plan Notes, the commencement of foreclosure proceedings, seeking the
appointment of a receiver, exercising its rights under the Guaranty, or
commencing involuntary bankruptcy proceedings against one or more of the
Borrowers.  Nothing contained in this Section 7.3(B) shall, or shall be deemed
to, prevent or delay the Lender from exercising any available rights and
remedies hereunder, under the Security Documents, at law or in equity
(including, without limitation, the rights and remedies described in items (i)
through (iv), above), upon the occurrence of any Major Default.

         7.4.    RIGHT OF SET-OFF.  Upon the occurrence of any Event of
Default, except as expressly provided in Section 7.3(B) hereof, the Lender may,
and is hereby authorized by the Borrowers, at any time and from time to time
thereafter, to the fullest extent permitted by





                                       54
<PAGE>   59

applicable Laws, and without advance notice to any of the Borrowers (any such
notice being expressly waived by the Borrowers), set-off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and any other Indebtedness at any time owing by the Lender to, or for the
credit or the account of, any of the Borrowers against any or all of the
Obligations of the Borrowers now or hereafter existing whether or not such
Obligations have matured and irrespective of whether the Lender has exercised
any other rights that it has or may have with respect to such Obligations,
including without limitation any acceleration rights.  The aforesaid right of
set-off may be exercised by the Lender against the Borrowers (or any of them)
or against any trustee in bankruptcy, debtor in possession, assignee for the
benefit of the creditors, receiver, or execution, judgment or attachment
creditor of any of the Borrowers, or such trustee in bankruptcy, debtor in
possession, assignee for the benefit of creditors, receiver, or execution,
judgment or attachment creditor, notwithstanding the fact that such right of
set-off shall not have been exercised by the Lender prior to the making, filing
or issuance, or service upon the Lender of, or of notice of, any such petition,
assignment for the benefit of creditors, appointment or application for the
appointment of a receiver or issuance of execution, subpoena, order or warrant.
The Lender agrees to promptly notify the Borrowers after any such set-off and
application, provided that the failure to give such notice shall not affect the
validity of such set-off and application.  The rights of the Lender under this
Section 7.4 are in addition to the other rights and remedies (including,
without limitation, other  rights of set-off) which the Lender may have.

         7.5.    WAIVER OF RIGHT TO STAY FORECLOSURE UPON OCCURRENCE OF MAJOR
DEFAULT.  In order to induce SouthTrust to enter into the transactions
contemplated in this Agreement and in the Plans, each of the Borrowers and the
Guarantor hereby waives any right or ability any of them may have to seek to
stop or stay a future foreclosure action brought by, or any other exercise of
legal or equitable rights or remedies by, the Lender upon the occurrence of any
one or more of the Major Defaults described in Section 7.1 (A), and each such
Borrower and the Guarantor hereby agree with, and for the benefit of, the
Lender, that they shall not be entitled to take any action to seek to stop or
stay any such exercise of Lender's remedies in any such event.

         7.6.    RELIEF FROM AUTOMATIC STAY. In order to induce SouthTrust to
enter into the transactions contemplated in this Agreement and in the Plans,
each of the Borrowers and the Guarantor hereby agrees that, in the event that
(A) any Bankruptcy Proceeding is filed by or against any of the Borrowers or
Guarantor, or which otherwise has jurisdiction over the Indebtedness evidenced
by the Plan Notes, this Agreement or the other Plan Documents (as defined in
the Plans), and (B) any such Bankruptcy Proceeding, or any action or omission
by any of the Borrowers or any Guarantor in connection therewith (including,
without limitation, any failure to timely comply with their payment or other
Obligations hereunder or under the Plan Notes), impairs or affects adversely
the Collateral or the rights and remedies of the Lender hereunder, then the
Lender automatically shall be entitled to relief from the automatic stay
provisions of Section 362 of the Bankruptcy Code or any successor or similar

         7.7.    ACKNOWLEDGMENT OF THE BORROWERS AND GUARANTOR.  The Borrowers
and the Guarantors hereby acknowledge that the provisions contained in Sections
7.5 and 7.6 were bargained for by the Lender, are required by the terms of the
Plans to be included in this Agreement, and are being relied upon by the Lender
in connection with its agreement to enter into the transactions contemplated by
this Agreement and the Plans.


ARTICLE 8.       MISCELLANEOUS


         8.1.    CONSTRUCTION.  The provisions of this Agreement shall be in
addition to those of any guaranty, pledge or security agreement, note or other
evidence of liability held by the Lender, all of which are incorporated herein
and shall be construed as complementary to each other.  Nothing herein
contained shall prevent the Lender from enforcing any or all other notes,
guaranty, pledge or security agreements in accordance with their respective
terms.

         8.2.    FURTHER ASSURANCE.  From time to time, the Borrowers will
execute and deliver to the Lender such additional documents and will provide
such additional information as the Lender may reasonably require to carry out
the terms of this Agreement and be informed of the status and affairs of the
Borrowers.

         8.3.    INDEMNITY.  The Borrowers hereby agree to indemnify the
Lender, all Participants, and its or their respective officers, directors,
agents and attorneys against, and to hold the Lender, all Participants, and all
such other persons harmless from, any claims, demands, liabilities, costs,
damages, and judgments (including, without limitation, liability under any
Environmental Laws and costs of defense and attorneys' fees) resulting from any
representation or warranty made by Borrowers or on Borrowers' behalf pursuant
to Article V of this Agreement having been false when made, or resulting from
Borrowers' breach of any of the covenants set forth in Article VI of this
Agreement.  This agreement of indemnity shall be a continuing agreement and
shall survive  payment of the Indebtedness evidenced by the Plan Notes and
termination of this Agreement.

         8.4.    ENFORCEMENT AND WAIVER BY THE LENDER.  The Lender shall have
the right at all times to enforce the provisions of this Agreement, the Plan
Notes, and the Security Documents in strict accordance with the terms hereof
and thereof, notwithstanding any conduct or custom on the part of the Lender in
refraining from so doing at any time or times.  The failure of the Lender at
any time or times to enforce its rights under such provisions, strictly in
accordance with the same, shall not be construed as having created a custom in
any way or manner contrary to specific provisions of this Agreement or as
having in any way or manner modified or waived the same. All rights and
remedies of the Lender are cumulative and concurrent and the exercise of one
right or remedy shall not be deemed a waiver or release of any other right or
remedy.

         8.5.    EXPENSES OF THE LENDER.  The Borrowers will, on demand,
reimburse the Lender for all expenses, including the fees and expenses of legal
counsel for the Lender, incurred (A) in connection with the preparation, and
negotiation of this Agreement and participation in the Closing, provided that
such fees and expenses of counsel shall not exceed $25,000.00, and (B) in





                                       56

connection with the administration, and any amendment, modification, renewal,
extension, or enforcement of this Agreement, the Plan Notes, the Security
Documents and any other documents related to this Agreement and the collection
or attempted collection of the Indebtedness evidenced by the Plan Notes.

this Agreement shall be in writing and shall be deemed delivered if delivered

applicable Laws, each of  the Borrowers:

                 8.7.1.   Waives: (1) protest of all commercial paper at any
time held by the Lender on which the Borrower is any way liable; and (2)
notice, after acceleration in the manner provided in Section , before exercise
by the Lender of the remedies of self-help, set-off, or of other summary
procedures permitted by any applicable Laws or by any agreement with any of the
Borrowers and except where required hereby or by any applicable Laws, notice of
any other action taken by the Lender; and

                 8.7.2.   Waives, in favor of the Lender and its successors and
assigns, any claims or defenses which any of the Borrowers or the Guarantor
have or may have with respect to this Agreement, the Plan Notes, the Original
SouthTrust Loan Documents or the Original SouthTrust Indebtedness, and each of
them hereby agrees further not to raise any such claims or defenses (if any)
against the Lender or its successors or assigns in any civil proceeding of any
kind or otherwise.

         8.8.    PARTICIPATION.  Notwithstanding any other provision of this
Agreement, each of the Borrowers understands that the Lender has heretofore
entered into, and may hereafter enter into, participation agreements with The
Daiwa Bank, Limited and other Participants, whereby the Lender has allocated or
will allocate certain percentages of the Obligations to them.  The Borrowers
acknowledge that, for the convenience of all parties, this Agreement is being
entered into with the Lender only and that its obligations under this Agreement
are undertaken for the benefit of, and as an inducement to each of any such
Participants as well as the Lender, and each of the Borrowers hereby grants to
each such Participant, to the extent of its participation in the Obligations,
the right to set off deposit accounts maintained by the Borrowers with such 
bank.

         8.9.    GOVERNING LAW.  This Agreement is entered into and performable
in Jefferson County, Alabama, and the substantive Laws of the United States and
the State of Alabama, without giving effect to its principles of conflict of
laws, shall govern the construction of this Agreement and the documents
executed and delivered pursuant hereto, and the rights and remedies of the
parties hereto and thereto, except to the extent that the location of any
Collateral in a state or jurisdiction other than Alabama requires that the
perfection of the Lender's security interest hereunder, and the enforcement of
certain of the Lender's remedies with respect to the Collateral, be governed by
the laws of such other state or jurisdiction.

         8.10.   SUBMISSION TO JURISDICTION; WAIVERS.
