                                    * * * * *

1.          THE ORIGINAL NOTES AND THE RECAPITALIZATION; THE NOTES; ADDITIONAL
            TRANSACTIONS

            Capitalized terms used in this Agreement shall have the meanings
assigned thereto in Section 9.

1.1.        The Original Notes.

            National Auto/Truckstops, Inc., a Delaware corporation ("National"),
is a wholly-owned Subsidiary of the Company. In order to provide the financing
for the acquisition of a truckstop network (the "National Network"), National
issued $65,000,000 aggregate principal amount of its 8.76% Senior Secured Notes
due 2002 (the "National Notes"). In order to provide the financing for the
acquisition of another truckstop network (the "TA Network" and, together with
the National Network, the "Network"), TA Operating Corporation, a Delaware
corporation ("TA"), which is a wholly-owned Subsidiary of the Company, issued
$25,000,000 aggregate principal amount of its Senior Secured Notes due 2002 (the
"TA Notes" and, together with the National Notes, the "Original Notes").

1.2.        The RECAPITALIZATION.

            In March 1997 the Company was recapitalized and restructured
pursuant to a series of transactions in which, inter alia, (a) TA became a
direct wholly-owned Subsidiary of the Company, (b) TA Franchise Systems Inc., a
Delaware corporation ("TAFSI"), became a direct wholly-owned Subsidiary of the
Company, (c) National and TA repaid certain outstanding Indebtedness, and (d)
the obligations of National in respect of the National Notes and TA in respect
of the TA Notes were discharged. The transactions described in the preceding
sentence are sometimes collectively referred to as the "Recapitalization".

            In order to finance the Recapitalization (i) the Company issued
$125,000,000 aggregate principal amount of its Senior Subordinated Notes due
2007 (the "Subordinated Notes"), 


                                      A-1
<PAGE>   13

(ii) $4,500,000 unpaid principal amount of TA Notes were redeemed, (iii) the
Company issued the Notes and the Floating Rate Notes in exchange for all
unredeemed Original Notes pursuant to the several Senior Secured Note Exchange
Agreements dated as of March 21, 1997 (the "Original Exchange Agreements")
between the Company and the institutional investors named in Schedule I thereto,
(iv) the Company entered into the Original Credit Agreement and borrowed
$80,000,000 under the Existing Term Loan Facility thereunder, and (v) the
Company made capital contributions or advances to National and TA in amounts
sufficient to enable National and TA to discharge their respective existing
Indebtedness and to pay accrued interest on the Original Notes, transaction
costs and other related expenses.

1.3.        The Notes.

            As part of the Recapitalization, the Company has duly authorized an
issue of its 8.94% Series I Senior Secured Notes due 2002 in an aggregate
principal amount of $35,500,000 (the "Notes"), each such note to mature, bear
interest and otherwise be substantially in the form of Exhibit A hereto. As used
herein, the term "Notes" shall include all notes originally issued pursuant to
this Agreement and the other agreements referred to in Section 4.27 and all
notes delivered in substitution or exchange for any of said notes and, where
applicable, shall include the singular number as well as the plural.

1.4.        Additional Transactions.

            Concurrently with the effectiveness of the Supplemental Agreement,
the Original Credit Agreement is being amended and restated in order to (a)
increase the commitments under the Term Loans by an aggregate amount of
$150,000,000 (the "Additional Term Loans"), (b) permit the Company to acquire
Burns' Travel Stops Division, (c) prepay the Floating Rate Notes pursuant to
Section 5.2 of the Original Exchange Agreements, (d) permit the Company under
certain conditions to effect the Additional Permitted Acquisition, (e) release
certain real property previously included in the Collateral and (f) effect other
amendments to the Original Credit Agreement. The transactions described in the
foregoing clauses (a) and (b), together with the amendment and restatement of
the Original Credit Agreement and the amendment to this Agreement pursuant to
the Supplemental 


                                      A-2
<PAGE>   14

Agreement, are referred to herein collectively as the "Additional Transactions".

            The proceeds of the Additional Term Loans to be made by the Lenders
are being used on and after the Restatement Closing Date solely to (i) fund the
cash purchase price of approximately $55,000,000 to be paid in connection with
the Burns Acquisition, (ii) prepay the Floating Rate Notes, (iii) fund up to
$30,000,000 of the cash purchase price to be paid in connection with the
Additional Permitted Acquisition, (iv) fund anticipated capital expenditures of
the Company and its Subsidiaries and (v) pay the fees and expenses incurred in
connection with the Additional Transactions.

1.5.        Security for the Notes.

            Effective as of the Restatement Closing Date, the Notes will be
unconditionally guaranteed by National, TA and TA Travel (individually, a
"Guarantor" and collectively with each other Person that is or becomes a party
to the Guarantee Agreement as a guarantor, and the permitted successors and
assigns of each such Person, the "Guarantors"), pursuant to an amended and
restated guarantee agreement, substantially in the form of Exhibit B-1 hereto,
between the Guarantors (other than TA Travel)and the Collateral Agent and a
guarantee agreement, substantially in the form of Exhibit B-2 hereto, between TA
Travel and the Collateral Agent (collectively, the "Guarantee Agreement").
Effective as of the Restatement Date, the Notes will be secured, equally and
ratably with the Term Facility and the Revolving Credit Facility (including the
Swingline Loans and the Letters of Credit) respectively provided pursuant to the
Credit Agreement, by the Security Documents, including, inter alia, (a)
mortgages, leasehold mortgages, deeds of trust and assignments of leases and
rents, substantially in the form of Exhibit C-1 hereto, from National or TA to
the Collateral Agent covering the Mortgaged Properties (collectively the
"Original Mortgages"), as respectively amended by any applicable Mortgage
Amendment (as so amended, the "Mortgages"), (b) the Airplane Mortgage,
substantially in the form of Exhibit C-2 hereto (b) an amended and restated
security agreement, substantially in the form of Exhibit D-1 hereto, between the
Company, the Guarantors (other than TA Travel) and TAFSI and the Collateral
Agent and a security agreement, substantially in the form of Exhibit D-2 hereto,
between the Company, TA Travel and the Collateral Agent (collectively, the
"Security Agreement"), (c) an amended and

between the Company, the Guarantors and TAFSI and the Collateral Agent (the
"Pledge Agreement"), (d) an amended and restated collateral assignment,
substantially in the form of Exhibit F hereto, from the Company, the Guarantors
and TAFSI to the Collateral Agent providing for the assignment to the Collateral
Agent of the Environmental Agreements, the Ancillary Agreements, the Franchise
Agreements, the Rate Protection Agreements and certain other agreements
specified in such Collateral Assignment (the "Collateral Assignment"), (e) one

5.          PREPAYMENT OF NOTES.

            In addition to the payment of the entire unpaid principal amount of
the Notes at the final maturity date thereof, the Company will make required,
and may make optional, prepayments of the Notes as hereinafter provided.

5.1.        Required Prepayment.

            On June 30, 2001, December 31, 2001 and June 30, 2002 the Company
will prepay $8,875,000 aggregate principal amount of the Notes (or, if less, the
unpaid balance thereof), at the principal amount to be prepaid, together with
accrued interest on such principal amount to the date of such prepayment,
without premium, whether or not any optional prepayment has been or is being
made pursuant to Section 5.2; provided that upon any partial prepayment of the
Notes pursuant to Section 5.3 or 5.4, 


                                      A-4
<PAGE>   16

the principal amount of each required prepayment of the Notes becoming due under
this Section 5.1 on and after the date of such partial prepayment shall be
reduced in the same proportion as the aggregate unpaid principal amount of the
Notes is reduced as a result of such partial prepayment.

5.2.        Optional Prepayments.

            The Company, upon not less than 10 or more than 30 days' prior
written notice of the date and amount of optional prepayment to the holders of
the Notes, may prepay at any time all or from time to time any part (in an
integral multiple of $1,000,000) of the Notes, upon payment of the principal
amount so to be prepaid, together with accrued interest on such principal amount
to the date of such prepayment and the Make-Whole Premium.

5.3.        Prepayments in Connection with Available Proceeds.

            (a) If at any time the Company shall have Available Proceeds (as
hereinafter defined), the Company will, promptly and in any event within five
days after such Available Proceeds are identified as such, give written notice
thereof to the holders of the Notes, which notice shall contain an irrevocable
offer by the Company to apply to the prepayment of the Notes (pro rata according
to the respective unpaid principal amounts of Notes held by each such holder) an
amount (rounded to the nearest $1,000) equal to such Available Proceeds, such
prepayment to be made on a date (the "Available Proceeds Prepayment Date")
specified in such notice (which date shall be not less than 10 days and not more
than 30 days after the date of such notice), in each case at the principal
amount so to be prepaid, together with accrued interest on such principal amount
to the Available Proceeds Prepayment Date but without premium. Each holder of a
Note may reject such offer (in whole but not in part with respect to any Note)
and shall be deemed to have rejected such offer unless such holder shall have
accepted such offer by notice delivered to the Company in writing or by telecopy
(or by telephone promptly confirmed in writing or by telecopy) at least three
Business Days prior to the Available Proceeds Prepayment Date. If any such
holder shall have rejected (or be deemed to have rejected) such prepayment
offer, such holder shall not be deemed to have waived its rights under this
Section 5.3 with respect to any later prepayment offer. A holder of more than
one Note may exercise its option under this Section in respect of all or any one
of its Notes. If any holder of Notes rejects or is 


                                      A-5
<PAGE>   17

deemed to have rejected such prepayment offer, then on the Available Proceeds
Prepayment Date the share of such Available Proceeds attributable to such Notes
shall be applied to the prepayment of obligations outstanding under the Credit
Agreement in accordance with paragraphs (e) and (f) of Section 2.13 thereof (or
the analogous provisions, if any, in respect of Refinancing Indebtedness).

            (b) The Company shall, not less than two Business Days prior to the
Available Proceeds Prepayment Date, deliver to each holder of Notes a notice
specifying (i) the aggregate principal amount of all Notes to be prepaid by the
Company on the Available Proceeds Prepayment Date, and (ii) the principal amount
of Notes held by such holder to be prepaid on the Available Proceeds Prepayment
Date.

            (c) [Intentionally Omitted].

            (d) In the case of any Prepayment Event or other event giving rise
to Available Proceeds, in respect of which the Company is required to prepay
Loans, Swingline Loans and Letters of Credit pursuant to Section 2.13 of the
Credit Agreement (or the analogous provisions in respect of Credit Agreement
Refinancing Indebtedness) prior to the Available Proceeds Prepayment Date, the
Company will, concurrently with such prepayment pursuant to the Credit Agreement
(or in respect of Credit Agreement Refinancing Indebtedness), make effective
provision whereby the Available Proceeds are placed in escrow with the
Collateral Agent until the Available Proceeds Prepayment Date whereupon such
amounts shall be applied to prepayments under this Section 5.3 (or the analogous
provisions in respect of Refinancing Indebtedness).

            (e) "Available Proceeds" means, at any date of determination,

            (i) in the case of Net Cash Proceeds resulting from a Prepayment
      Event, an amount equal to the Pro Rata Share of the holders of the Notes
      in respect of such Net Cash Proceeds, and

            (ii) in the case of any fiscal year of the Company, commencing with
      the fiscal year ending on December 31, 1999, for which Excess Cash Flow
      exists, 50% of Excess Cash Flow for such fiscal year less the portion, if
      any, of such percentage applied (or required concurrently to be applied)


                                      A-6
<PAGE>   18

      pursuant to Section 2.13(c) of the Credit Agreement (or the analogous
      provisions in respect of Credit Agreement Refinancing Indebtedness) to the
      prepayment of obligations under the Credit Agreement (or in respect of
      Credit Agreement Refinancing Indebtedness).

            The Company will furnish to the holders of the Notes, concurrently
with the financial statements and other information furnished pursuant to
Sections 6.4(a) and (b), a certificate of a Financial Officer of the Company
containing computations in reasonable detail showing whether any Available
Proceeds existed during the fiscal period covered by such financial statements
and the source of such Available Proceeds.

5.4.        Prepayment in Connection with a Change in Control.

            Promptly and in any event within five Business Days after the
occurrence of a Change in Control, the Company will give written notice thereof
to the holders of the Notes, which notice shall (a) describe the Change in
Control in reasonable detail and specify the Change in Control Prepayment Date
and the Response Date (as respectively defined below) in respect thereof, (b)
contain an irrevocable offer by the Company to prepay all Notes at the prices
specified below on the date therein specified (the "Change in Control Prepayment
Date"), which shall be not less than 20 nor more than 45 days after the date of
such notice, and (c) state that such offer is conditioned upon acceptance
thereof by the Required Holders. Each holder of a Note shall notify the Company
of such holder's acceptance or rejection of such offer by giving written notice
of such acceptance or rejection to the Company at least 10 days prior to the
Change in Control Prepayment Date (the "Response Date"). If the Required Holders
accept such offer, the Company shall, no later than two days after the Response
Date, send written notice of such acceptance to each holder of a Note which had
rejected such offer, which notice shall advise each such holder that it may, by
notice to the Company no later than five days prior to the Change in Control
Prepayment Date, rescind its prior rejection and accept such offer. The failure
by the holder of a Note to respond to such offer in writing on or before the
Response Date shall be deemed to be a rejection of such offer by such holder in
respect of such Change in Control. The Company shall (but only if the Required
Holders shall have accepted such offer as provided above) prepay on the Change
in Control Prepayment Date all of the Notes held by the holders as to which such
offer has 


                                      A-7
<PAGE>   19

been so accepted, at the unpaid principal amount of each such Note, together
with accrued interest thereon to the Change in Control Prepayment Date and the
Make-Whole Premium with respect to such Note. If the Required Holders fail to
accept such offer, such offer shall be deemed to be rejected (and any
acceptances thereof shall be ineffective) and the Company shall give written
notice thereof to the holders of all Notes no more than five days after the
Response Date. If any holder shall reject such prepayment offer and, if
applicable, not exercise its right to rescind such rejection, such holder shall
be deemed to have waived its rights under this Section 5.4 to require prepayment
of all Notes held by such holder in respect of such Change in Control but not in
respect of any subsequent Change in Control. A holder of more than one Note may
exercise its option under this Section 5.4 in respect of all or any one of such
Notes.

5.5.        Obligation to Prepay after Notice; Make-Whole Computation.

            The principal amount of the Notes designated for prepayment in any
notice of optional prepayment given pursuant to Section 5.2 shall become due and
payable on the date fixed for prepayment, together with accrued interest on such
principal amount to the date of such prepayment and the amount of any Make-Whole
Premium. Two Business Days prior to the date fixed for any prepayment under this
Agreement that includes a Make-Whole Premium, the Company will furnish to each
holder of a Note being so prepaid a certificate signed by a Financial Officer of
the Company setting forth in reasonable detail the computation and the
methodology and assumptions made in connection therewith and attaching a copy of
the source of the market data by which the Treasury Yield was determined in
connection with such computation.

5.6.        Application of Prepayments.

            Each prepayment of less than all outstanding Notes pursuant to
Section 5.1 or 5.2 shall be applied by the Company pro rata, as nearly as may
be, to all outstanding Notes according to the respective unpaid principal
amounts thereof.

5.7.        Note Purchase Prohibition.

            The Company will not, and will not permit any of its Affiliates to,
directly or indirectly acquire any Note, by purchase or otherwise, except (a) by
way of payment or prepayment 


                                      A-8
<PAGE>   20

thereof by the Company in accordance with the provisions of the Notes and of
this Agreement or (b) pursuant to an offer to purchase made by any such
Affiliate and which complies with the following conditions:

            (i) such offer shall require such Affiliate to purchase Notes on the
      same terms and conditions, pro rata among all Notes tendered; and

            (ii) such purchase shall not be made, directly or indirectly, in
      connection with and in anticipation of or in consideration of any waiver
      or amendment of any provision of this Agreement or any Transaction
      Document.

            Promptly and in any event within five Business Days after each such
purchase of Notes, the Company will furnish each holder of the Notes with a
certificate of a Financial Officer describing such purchase (including the
aggregate principal amount of Notes so purchased and the purchase price
therefor) and certifying that such purchase was made in compliance with the
requirements of this Section.

6.          AFFIRMATIVE COVENANTS.

            The Company covenants and agrees that, so long as any of the Notes

may be afforded by an "all risk" policy or a fire policy covering "special"
causes of loss, including building ordinance law endorsements; cause all such
policies to be endorsed or otherwise amended to include a "standard" or "New

insurance carrier shall not have received written notice from any holder of a
Note or the Collateral Agent that an Event of Default has occurred and, if

delivered to the Collateral Agent) together with evidence satisfactory to the
Collateral Agent of payment of the premium therefor; and cause each all risk
policy maintained by the Company or any Guarantor to be endorsed to provide for
a waiver by the related insurer of all its rights to recovery against any
Network Operator for damage covered by such policy. 

            (b) If at any time the area in which the Premises (as defined in the
Mortgages) are located is designated (i) a "flood hazard area" in any Flood

<PAGE>   23

be maintained under this Section 6.2 is taken out by the Company, any Guarantor
or any Network Operator; and promptly deliver to the Collateral Agent a
duplicate original copy of such policy or policies. 

            (e) Use its reasonable efforts to cause the Phase II Consultant (as
defined in the Environmental Agreements) to maintain, and name the Company as an
additional insured wherever permissible under the contracts of insurance,
coverage at levels at least as high as set forth in Schedule 6.2(e). 

            (f) In connection with the covenants set forth in this Section 6.2,
it is understood and agreed as follows: 

            (i) Neither the Noteholder nor the holders from time to time of the
      Notes, nor their agents or employees shall be liable for any loss or
      damage insured by the insurance policies required to be maintained under
      this Section 6.2, it being understood that (A) the Company shall look, and
      shall cause each Guarantor to look, solely to its insurance company or any
      other parties other than the aforesaid parties for the recovery of such
      loss or damage and (B) such insurance company shall have no rights of
      subrogation against the Noteholder or any such holder or their agents or
      employees. If, however, the insurance policies do not provide waiver of
      subrogation rights against such parties, as requested above, then the
      Company hereby agrees, to the extent permitted by law, to waive its right
      of recovery, if any, against the Noteholder, the holders from time to time
      of the Notes and their agents and employees.

            (ii) The designation of any form, type or amount of insurance
      coverage by the Noteholder, any holder of a Note or the Collateral Agent
      under this Section 6.2, shall in no event be deemed a representation,
      warranty or advice by the Noteholder, such holder or the Collateral Agent
      that such insurance is adequate for the purposes of the Company's and each
      Guarantor's business or the protection of the Company's and each
      Guarantor's properties and the Required Holders and the Collateral Agent
      shall have the right from time to time to require the Company to keep
      (and/or cause any Guarantor or the related Network Operator, if any, to
      keep) other insurance in such form and amount as the Required Holders or
      the Collateral Agent may reasonably request, provided that


                                      A-12
<PAGE>   24

      such insurance shall be obtainable on commercially reasonable terms. 

6.3.        Obligations and Taxes.

            Pay its Indebtedness and other obligations promptly and in
accordance with their terms and pay and discharge promptly when due all material
taxes, assessments and governmental charges or levies imposed upon it or upon
its income or profits or in respect of its property, before the same shall
become delinquent or in default, as well as all lawful claims for labor,
materials and supplies or otherwise that, if unpaid, might give rise to a Lien
upon such properties or any part thereof; provided, however, that such payment
and discharge shall not be required with respect to any such obligation, tax,
assessment, charge, levy or claim so long as the validity or amount thereof
shall be contested in good faith by appropriate proceedings and the Company, a
Guarantor or TAFSI, as applicable, shall have set aside on its books adequate
reserves with respect thereto in accordance with GAAP and such contest operates
to suspend collection of the contested obligation, tax, assessment or charge and
enforcement of a Lien and, in the case of a Mortgaged Property, there is no risk
of forfeiture of such property.

<PAGE>   93

      such Reportable Event or Reportable Events or the failure to make a

      Company, such Guarantor, TAFSI or such ERISA Affiliate does not have
      reasonable grounds for contesting such Withdrawal Liability or is not in
      fact contesting such Withdrawal Liability in a timely and appropriate
      manner and (iii) the amount of the Withdrawal Liability specified in such
      notice, when aggregated with all other amounts required to be paid to
      Multiemployer Plans in connection with Withdrawal Liabilities (determined
      as of the date or dates of such notification), either (a) is $2,000,000 or
      more and the Required Holders have reasonably determined that the Company,

      less than $2,000,000 and any payment due as a result of such liability
      remains unpaid 30 days after such payment is due;

            (l) the Company, any Guarantor, TAFSI or any ERISA Affiliate shall
      have been notified by the sponsor of a Multiemployer Plan that such
      Multiemployer Plan is in reorganization or is being terminated, within the
      meaning of Title IV of ERISA, if solely as a result of such reorganization
      or termination the aggregate annual contributions of the Company, each
      Guarantor, TAFSI and each ERISA Affiliate to all Multiemployer Plans that
      are then in reorganization or have been or are being terminated have been
      or will be increased over the amounts required to be contributed to such

      amount exceeding $2,000,000 and the Required Holders have reasonably


                                      A-82
<PAGE>   94

      determined that the Company, such Guarantor, TAFSI or such ERISA Affiliate

      contribution; (m) any material security interest purported to be created
      by any Security Document shall cease to be, or shall be asserted by the
      Company, any Guarantor or TAFSI not to be, a valid, perfected, first
      priority (except as otherwise expressly provided in this Agreement or such
      Security Document) security interest in the securities, assets or
      properties covered thereby, except to the extent that any such loss of
      perfection or priority results from the failure of the Collateral Agent to
      maintain possession of certificates representing securities pledged under
      the Pledge Agreement (except to the extent that such loss is covered by a
      lender's title insurance policy and the related insurer promptly after
      such loss shall have acknowledged in writing that such loss is covered by
      such title insurance policy);

            (n) any Financing Document shall not be for any reason or shall be

      terms;

            (o) the Obligations and the guarantees thereof pursuant to the

      subordination provisions of the Subordinated Notes, the Subordinated
      Guarantees and the Subordinated Note Indenture (or the provisions of the
      Subordinated Note Refinancing Indebtedness) or such subordination
      provisions shall be invalidated or otherwise cease to be a legal, valid
      and binding obligation of the parties thereto, enforceable in accordance
      with their terms; or

            (p) any material provision of the Guarantee Agreement or any other
      Financing Document shall cease to be in full force and effect and
      enforceable in accordance with its terms for any reason whatsoever or any
      Guarantor or TAFSI shall contest or deny in writing the validity or
      enforceability of any of its obligations under the Guarantee Agreement or
      any other Financing Document, as applicable, or the Notes shall cease to
      be entitled to the benefits of any 


                                      A-83
<PAGE>   95

      Security Document, this Agreement, or the Intercreditor Agreement for any
      reason whatsoever;

then (i) upon the occurrence of an Event of Default with respect to the Company
or any of its Subsidiaries described in subsection (g) or (h) above, the unpaid
principal amount of all Notes, together with the interest accrued thereon, shall
automatically become immediately due and payable, without presentment, demand,
protest or other requirements of any kind, all of which are hereby expressly
waived by the Company or (ii) upon the occurrence and continuance of any other
Event of Default, the Required Holders may, by written notice to the Company,
declare the unpaid principal amount of all Notes to be, and the same shall
forthwith become, due and payable, together with the interest accrued thereon
and, to the extent permitted by law, an amount equal to the Additional Amount
(as hereinafter defined) in respect of each such Note, provided that during the
existence of an Event of Default described in subsection (b) or (c) above with
respect to any Note, the holder of such Note may, by written notice to the
Company, declare such Note to be, and the same shall forthwith become, due and
payable, together with the interest accrued thereon and, to the extent permitted
by law, an amount equal to the Additional Amount. If any holder of any Note
shall exercise the option specified in the proviso to the preceding sentence,
the Company will forthwith give written notice thereof to the holders of all
other outstanding Notes and each such holder may (whether or not such notice is
given or received), by written notice to the Company, declare the unpaid
principal amount of all Notes held by it to be, and the same shall forthwith
become, due and payable, together with the interest accrued thereon and, to the
extent permitted by law, an amount equal to the Additional Amount. If all Notes
are accelerated as specified above, the Company will forthwith give written
notice thereof to any holder of an outstanding Note which has not given written
notice to the Company with respect to such acceleration.

            Notwithstanding the foregoing, in the event that a non-payment
default under subsection (a), (d) or (e) above is solely the result of any
Network Operator's failure to perform its obligations to any Guarantor pursuant
to any operating lease with such Guarantor permitted by Section 7.8, then, so
long as (i) there shall not be a similar failure by more than two other Network
Operators and (ii) such Guarantor has rights against such Network Operator with
respect to such default and has commenced


                                      A-84
<PAGE>   96

enforcement of its rights against such Network Operator (including compelling
such Network Operator to cure such default, exercising such Guarantor's
self-help remedies as landlord under such operating lease or terminating such
operating lease and taking possession of the premises within the time for cure
as provided herein) and the Required Holders, in their reasonable judgment, are
satisfied that such Guarantor is diligently and with best efforts prosecuting
such enforcement until cure of such default, no Event of Default shall be deemed
to have occurred hereunder with respect thereto.

            For purposes of this Section, the term "Additional Amount" means an
amount equal to the Make-Whole Premium that would be payable with respect to
such Note if the Company had elected to prepay such Note in full pursuant to
Section 5.2 on the date of acceleration.

            The provisions of this Section are subject, however, to the
condition that if, at any time after all Notes have been declared due and
payable as aforesaid by the Required Holders, the Company shall pay all arrears
of interest on the Notes and all payments on account of the principal of and
premium (if any) on the Notes which shall have become due otherwise than by
acceleration (with interest on such principal, premium (if any) and, to the
extent permitted by law, on overdue payments of interest, at the rate specified
in the Notes with respect to overdue payments) and all Events of Default (other
than nonpayment of principal of and accrued interest on Notes due and payable
solely by virtue of acceleration) shall be remedied or waived pursuant to
Section 13, then the holders of at least 75% of the aggregate unpaid principal
amount of the Notes at the time outstanding may, by written notice to the
Company, rescind and annul any such acceleration and its consequences; but no
such action shall affect any subsequent Default or Event of Default or impair
any right consequent thereon.

13.         AMENDMENT AND WAIVER.

            (a) Any provision of this Agreement or the Notes may, with the
consent of the Company, be amended or waived (either generally or in a
particular instance and either retroactively or prospectively), by one or more
substantially concurrent written instruments signed by the Required Holders
(subject to the 


                                      A-85
<PAGE>   97

provisions of the Intercreditor Agreement) provided, however, that

            (i) no such amendment or waiver shall

                  (A) change the rate or the time of payment of interest on any
            of the Notes, change the maturity of any of the Notes or affect the
            premium payable on any prepayment of a Note, modify any of the other
            provisions of this Agreement with respect to the payment or
            prepayment or purchase of any Note, modify this Section 13 or
            Section 14, reduce the percentage of the principal amount of the
            Notes the holders of which are required to approve any such
            amendment or effectuate any such amendment or effectuate any such
            waiver, or change the percentage of the principal of the Notes the
            holders of which are required to accelerate the maturity of the
            Notes or rescind any such acceleration, without the consent of the
            holders of all the Notes then outstanding, or

                  (B) modify the definition of "Make-Whole Premium" without the
            consent of the holder of each Note affected thereby, and

            (ii) no such waiver shall extend to or affect any obligation not
expressly waived or impair any right consequent thereon.
