when and as such Obligation becomes due and payable in accordance with the terms
of the Loan Agreement and the Notes, whether such Obligation is outstanding on
the date hereof or arises or is incurred hereafter. The guaranty hereby made by

and punctual payment by the Borrower of all of the Obligations in accordance
with the terms of the Loan Agreement and not of their collectibility only and is
in no way conditioned upon any requirement that the Bank first attempt to
collect any of the Obligations from the Borrower or resort to any other
security, collateral or other means of obtaining payment of any of the
Obligations which the Bank now has or may acquire after the date hereof, or upon
any other contingency whatsoever.

     Section 2.2. Payments. If the Borrower shall fail to make any payment of
any Obligation punctually when and as such obligation shall become due and
payable and such failure shall continue beyond the period of grace, if any,
applicable thereto, then the Guarantor hereby agrees to make such payment of
such Obligation, in funds immediately available to the Bank, upon written demand
by the Bank.

rights, remedies, powers and privileges of the Bank hereunder shall not in any
way be prejudiced or affected by an intermediate payment by the Borrower of any
part of the Obligations. This Guaranty and the obligations of the Guarantor
hereunder shall be in addition to and shall not in any way be prejudiced or
affected by any other collateral or other security or guarantees now or
hereafter held by the Bank for all or any part of the Obligations, and every
right, remedy, power or privilege given to the Bank hereunder shall be in
addition to and not a limitation of any and every other right, remedy, power or
privilege vested in the Bank under any other collateral. No assurances, security
or payment of any of the Obligations which is avoided under any enactment
relating to bankruptcy, liquidation or insolvency, and no release, settlement or
discharge given or made by the Bank on the faith of any such assurance, security
or payment shall prejudice or affect the right of the Bank to recover from the
Guarantor to the full extent of the guaranty hereby made by the Guarantor as if
such assurance, security, payment, release, settlement or discharge (as the case
may be) had never been given or made.

     Section 3. Demands for Payment. Each demand for payment pursuant to Section
2.2 hereof shall be made in accordance with the terms of Section 18 hereof.
Demands for payment hereunder may be made on any number of occasions. A dated
statement signed by an officer of the Bank and setting forth the amount of the
Obligations at the time owing to the Bank, or (as the case may be) setting forth
the amount of the obligations at the time owing by the Guarantor to the Bank
pursuant to Section 9 hereof, shall, save for manifest error, be prima facie
evidence thereof as between the Guarantor and the Bank in any legal proceedings
against the Guarantor in connection with this Guaranty.

     Section 4. Waivers of Notice, Assent, Etc. The Guarantor hereby waives
notice of acceptance of this Guaranty, notice of any and all loans or advances
made or other financial accommodations extended to the Borrower by the Bank
under the Loan Agreement, notice of the occurrence of any default or of any
demand upon the Borrower for any payment under the Loan Agreement, notice of any
action at any time taken or omitted by the Bank under or in respect of the Loan
Agreement or any of the Obligations, any requirement of diligence or to mitigate
damages and, generally, all demands, notices and other formalities of every kind
in connection with this Guaranty (except as otherwise expressly provided
hereby), the Loan Agreement or any of the Obligations. The Guarantor hereby
assents to, and waives notice of, any extension or postponement of

<PAGE>   5

                                      -5-

the time for the payment of any of the Obligations, the acceptance of any
partial payment thereon, any waiver, consent or other action or acquiescence by
the Bank at any time or times in respect of any default by the Borrower in the
performance or satisfaction of any term, covenant, condition or provision of the
Loan Agreement, any amendment, modification or waiver to the Loan Agreement, the
Notes or any other Loan Document, any and all other indulgences whatsoever by
the Bank in respect of any of the Obligations or otherwise, the taking,
addition, substitution or release, in whole or in part, at any time or times, of
any security for any of the Obligations, the addition, substitution or release,
in whole or in part, of any person or persons (other than the Borrower)
primarily or secondarily liable in respect of any of the Obligations or any
other events or circumstances which might constitute a legal or equitable
discharge of a surety or guaranty. Without limitation of the generality of the
foregoing, the Guarantor assents to any other action or delay in acting or
failure to act on the part of the Bank, including, without limitation, any
failure strictly or diligently to assert any right or pursue any remedy or to
mitigate damages or to comply fully with applicable laws or regulations
thereunder, which might, but for the provisions of this Section 4 hereof, afford
grounds for terminating, discharging or relieving the Guarantor, in whole or in
part, from any of its absolute and unconditional obligations hereunder, it being
the intention of the Guarantor that, so long as any of the Obligations remains
unsatisfied, the obligations of the Guarantor hereunder shall not be discharged
except by payment and then only to the extent of such payment. The obligations
of the Guarantor hereunder shall not be diminished or rendered unenforceable by
any bankruptcy, winding up, reorganization, arrangement, liquidation or similar
proceeding with respect to the Borrower, the Guarantor or the Bank. The guaranty
hereby made by the Guarantor shall continue in full force and effect
notwithstanding any absorption, merger, amalgamation or any other change
whatsoever in the name, membership, constitution or place of formation of the
Borrower, the Guarantor or the Bank.

     Section 5. Place and Mode of Payments. Each payment by the Guarantor under
or in respect of this Guaranty shall be made to the Bank in immediately
available and freely transferable funds at the Bank's office at One Federal
Street, Boston, Massachusetts 02110, Attention: Michael A. Palmer, Vice
President.

     Section 6. Set-off. Regardless of the adequacy of any collateral or other
means of obtaining prepayment of the Obligations, the Bank may at any time and
without prior notice to the Guarantor set-off the whole or any portion or
portions of any or all deposits and other sums credited by or due from the Bank
to the Guarantor against amounts payable under this

<PAGE>   6

                                      -6-

Guaranty, whether or not any other person or persons could also withdraw money
therefrom. The Bank will promptly thereafter notify the Guarantor of any such
set-off.

     Section 7. Freedom to Deal with Borrower and Other Banks. The Bank shall be
at liberty, without giving notice to or obtaining the assent of the Guarantor
and without relieving the Guarantor of any liability hereunder, to deal with the
Borrower and with each other party who now is or after the date hereof becomes
liable in any manner for any of the Obligations, in such manner as the Bank in
its sole discretion deems fit, and to this end the Guarantor agrees that the
Bank may in its sole discretion do any or all of the following things: (a)
extend credit, make loans and afford other financial accommodations to the
Borrower at such times, in such amounts and on such terms as the Bank may
approve, (b) vary the terms and grant extensions or renewals of any present or
future indebtedness or obligation to the Bank of the Borrower or of any such
other party, (c) grant time, waivers and other indulgences in respect thereto,
(d) vary, exchange, release or discharge, wholly or partially, or delay in or
abstain from perfecting and enforcing any security or guaranty or other means of
obtaining payment of any of the Obligations which the Bank now have or acquire
after the date hereof, (e) accept partial payments from the Borrower or any such
other party, (f) release or discharge, wholly or partially, any endorser or
guarantor, and (g) compromise or make any settlement or other arrangement with
the Borrower or any such other party.

     Section 8. Election of Remedies. This Guaranty may be enforced by the Bank
from time to time as often as occasion therefor may arise and without any
requirement on the part of the Bank first to exercise any rights against the
Borrower or any other person or to exhaust any remedies available to the Bank
against the Borrower or any other person or to resort to any collateral or
security for any of the Obligations which is in the possession or under the
control of the Bank or to resort to any other source or means of obtaining
payment or enforcing payment of the Obligations or any of them.

     Section 9. Expenses. The Guarantor hereby agrees to pay upon demand by the
Bank all reasonable out-of-pocket costs and expenses, including, but not limited
to, court costs and expenses and the fees and disbursements of lawyers, incurred
or expended by the Bank in connection with the enforcement of this Guaranty,
together with interest on amounts recoverable under this Section 9 hereof from
the time such amounts become due until payment at the rate applicable to amounts
overdue under the Loan

<PAGE>   7

                                      -7-

Agreement. The covenant contained in this Section 9 hereof shall survive the
payment in full of all of the Obligations.

     Section 10. Further Assurances. The Guarantor will, at any time and from
time to time, upon request by the Bank, take or cause to be taken any action and
execute and deliver such, if any, further documents as, in the reasonable
opinion of the Bank, are necessary in order to give full effect to this Guaranty
and to preserve the rights, powers, privileges and remedies of the Bank
hereunder.

     Section 11. Waiver of Certain Defenses. The Guarantor hereby absolutely and
irrevocably waives, to the fullest extent permitted by law, any and all defenses
which may now or hereafter exist in respect of its obligations hereunder by
virtue of any statute of limitations, stay or moratorium law or other similar
law now or hereafter in effect.

     Section 12. Unenforceability of Obligations Against Borrower, Etc. It is
hereby agreed as a separate and independent stipulation that, if for any reason
the Borrower ceases to have any legal obligation to discharge the Obligations or
any of them, or if any of the moneys included in the Obligations have become
irrecoverable from the Borrower by operation of law or for any other reason, or
if any of the Obligations become unenforceable against the Borrower by operation
of law or for any other reason, this Guaranty and the obligations of the
Guarantor hereunder shall nevertheless be binding on the Guarantor to the same
extent as if the Guarantor at all times prior to demand by the Bank for payment
hereunder had been, and at the time of, such demand was, the principal debtor on
all of such Obligations.

     Section 13. Amendments and Waivers. Neither this Guaranty nor any term
hereof may be changed, waived, discharged or terminated except by an instrument
in writing signed by the Bank and the Guarantor expressly referring to this
Guaranty and to the provisions so changed, waived, discharged or terminated. No
such waiver shall extend to or affect any obligation not expressly waived or
impair any right consequent thereon. No course of dealing by the Bank and no
delay or omission on the part of the Bank in exercising any right or remedy
hereunder shall operate as a waiver of that or any other right or remedy
hereunder or otherwise be prejudicial thereto.

     Section 14. Representations and Warranties of the Guarantor. The Guarantor
represents and warrants to the Bank that on and as of the date hereof:

     Borrower is a party has occurred during the fiscal year in question or
     exists at the date of such certificate or, if in the opinion of such firm a

when and as such Obligation becomes due and payable in accordance with the terms
of the Loan Agreement and the Notes, whether such Obligation is outstanding on
the date hereof or arises or is incurred hereafter. The guaranty hereby made by

any way be prejudiced or affected by an intermediate payment by the Borrower of
any part of the Obligations. This Guaranty and the obligations of the Guarantor
hereunder shall be in addition to and shall not in any way be prejudiced or
affected by any other collateral or other security or guarantees now or
hereafter held by the Bank for all or any part of the Obligations, and every
right, remedy, power or privilege given to the Bank hereunder shall be in
addition to and not a limitation of any and every other right, remedy, power or
privilege vested in the Bank under any other collateral. No assurances, security
or payment of any of the Obligations which is avoided under any enactment

or payment shall prejudice or affect the right of the Bank to recover from the
Guarantor to the full extent of the guaranty hereby made by the Guarantor as if
such assurance, security, payment, release, settlement or discharge (as the case
may be) had never been given or made.

         SECTION 3. Demands for Payment. Each demand for payment pursuant to
section 2.2 hereof shall be made in accordance with the terms of section 18
hereof. Demands for payment hereunder may be made on any number of occasions. A

the Obligations at the time owing to the Bank, or (as the case may be) setting
forth the amount of the obligations at the time owing by the Guarantor to the
Bank pursuant to section 9 hereof, shall, save for manifest error, be prima
facie evidence thereof as between the Guarantor and the Bank in any legal
proceedings against the Guarantor in connection with this Guaranty.

         SECTION 4. Waivers of Notice, Assent, Etc. The Guarantor hereby waives

action at any time taken or omitted by the Bank under or in respect of the Loan
Agreement or any of the Obligations, any requirement of diligence or to mitigate
damages and, generally, all demands, notices and other formalities of every kind

assents to, and waives notice of, any extension or postponement of

<PAGE>   5
                                      -5-

the time for the payment of any of the Obligations, the acceptance of any
partial payment thereon, any waiver, consent or other action or acquiescence by
the Bank at any time or times in respect of any default by the Borrower in the
performance or satisfaction of any term, covenant, condition or provision of the
Loan Agreement, any amendment, modification or waiver to the Loan Agreement, the
Notes or any other Loan Document, any and all other indulgences whatsoever by
the Bank in respect of any of the Obligations or otherwise, the taking,
addition, substitution or release, in whole or in part, at any time or times, of
any security for any of the Obligations, the addition, substitution or release,
in whole or in part, of any person or persons (other than the Borrower)
primarily or secondarily liable in respect of any of the Obligations or any
other events or circumstances which might constitute a legal or equitable
discharge of a surety or guaranty. Without limitation of the generality of the
foregoing, the Guarantor assents to any other action or delay in acting or
failure to act on the part of the Bank, including, without limitation, any
failure strictly or diligently to assert any right or pursue any remedy or to
mitigate damages or to comply fully with applicable laws or regulations
thereunder, which might, but for the provisions of this SECTION 4 hereof, afford
grounds for terminating, discharging or relieving the Guarantor, in whole or in
part, from any of its absolute and unconditional obligations hereunder, it being
the intention of the Guarantor that, so long as any of the Obligations remains
unsatisfied, the obligations of the Guarantor hereunder shall not be discharged
except by payment and then only to the extent of such payment. The obligations
of the Guarantor hereunder shall not be diminished or rendered unenforceable by
any bankruptcy, winding up, reorganization, arrangement, liquidation or similar
proceeding with respect to the Borrower, the Guarantor or the Bank. The guaranty
hereby made by the Guarantor shall continue in full force and effect
notwithstanding any absorption, merger, amalgamation or any other change
whatsoever in the name, membership, constitution or place of formation of the
Borrower, the Guarantor or the Bank.

         SECTION 5. Place and Mode of Payments. Each payment by the Guarantor

available and freely transferable funds at the Bank's office at One Federal
Street, Boston, Massachusetts 02110, Attention: Michael A. Palmer, Vice
President.

         SECTION 6. Set-off. Regardless of the adequacy of any collateral or
other means of obtaining prepayment of the Obligations, the Bank may at any time
and without prior notice to the Guarantor set-off the whole or any portion or
portions of any or all deposits and other sums credited by or due from the Bank
to the Guarantor against amounts payable under this

<PAGE>   6
                                      -6-

Guaranty, whether or not any other person or persons could also withdraw money
therefrom. The Bank will promptly thereafter notify the Guarantor of any such
set-off.

         SECTION 7. Freedom to Deal with Borrower and Other Banks. The Bank
shall be at liberty, without giving notice to or obtaining the assent of the
Guarantor and without relieving the Guarantor of any liability hereunder, to
deal with the Borrower and with each other party who now is or after the date
hereof becomes liable in any manner for any of the Obligations, in such manner
as the Bank in its sole discretion deems fit, and to this end the Guarantor
agrees that the Bank may in its sole discretion do any or all of the following
things: (a) extend credit, make loans and afford other financial accommodations
to the Borrower at such times, in such amounts and on such terms as the Bank may
approve, (b) vary the terms and grant extensions or renewals of any present or
future indebtedness or obligation to the Bank of the Borrower or of any such
other party, (c) grant time, waivers and other indulgences in respect thereto,
(d) vary, exchange, release or discharge, wholly or partially, or delay in or
abstain from perfecting and enforcing any security or guaranty or other means of
obtaining payment of any of the Obligations which the Bank now have or acquire
after the date hereof, (e) accept partial payments from the Borrower or any such
other party, (f) release or discharge, wholly or partially, any endorser or
guarantor, and (g) compromise or make any settlement or other arrangement with
the Borrower or any such other party.

         SECTION 8. Election of Remedies. This Guaranty may be enforced by the
Bank from time to time as often as occasion therefor may arise and without any
requirement on the part of the Bank first to exercise any rights against the
Borrower or any other person or to exhaust any remedies available to the Bank
against the Borrower or any other person or to resort to any collateral or
security for any of the Obligations which is in the possession or under the
control of the Bank or to resort to any other source or means of obtaining
payment or enforcing payment of the Obligations or any of them.

         SECTION 9. Expenses. The Guarantor hereby agrees to pay upon demand by
the Bank all reasonable out-of-pocket costs and expenses, including, but not
limited to, court costs and expenses and the fees and disbursements of lawyers,
incurred or expended by the Bank in connection with the enforcement of this
Guaranty, together with interest on amounts recoverable under this section 9
hereof from the time such amounts become due until payment at the rate
applicable to amounts overdue under the Loan

<PAGE>   7
                                      -7-

Agreement. The covenant contained in this section 9 hereof shall survive the
payment in full of all of the Obligations.

         SECTION 10. Further Assurances. The Guarantor will, at any time and
from time to time, upon request by the Bank, take or cause to be taken any
action and execute and deliver such, if any, further documents as, in the
reasonable opinion of the Bank, are necessary in order to give full effect to
this Guaranty and to preserve the rights, powers, privileges and remedies of the
Bank hereunder.

         SECTION 11. Waiver of Certain Defenses. The Guarantor hereby absolutely
and irrevocably waives, to the fullest extent permitted by law, any and all
defenses which may now or hereafter exist in respect of its obligations
hereunder by virtue of any statute of limitations, stay or moratorium law or
other similar law now or hereafter in effect.

         SECTION 12. Unenforceability of Obligations Against Borrower, Etc. It
is hereby agreed as a separate and independent stipulation that, if for any
reason the Borrower ceases to have any legal obligation to discharge the
Obligations or any of them, or if any of the moneys included in the Obligations
have become irrecoverable from the Borrower by operation of law or for any other
reason, or if any of the Obligations become unenforceable against the Borrower
by operation of law or for any other reason, this Guaranty and the obligations
of the Guarantor hereunder shall nevertheless be binding on the Guarantor to the
same extent as if the Guarantor at all times prior to demand by the Bank for
payment hereunder had been, and at the time of, such demand was, the principal
debtor on all of such Obligations.

         SECTION 13. Amendments and Waivers. Neither this Guaranty nor any term
hereof may be changed, waived, discharged or terminated except by an instrument

deficiency", as such term is defined in Section 302 of ERISA, whether or not
waived, or (c) terminate any such benefit plan in a manner which could result in

stores or other businesses which can reasonably be conducted at gasoline service
stations or convenience stores, except that the Guarantor may engage in any

         SECTION 18. Notices, Etc. (a) The Bank shall provide the Guarantor with
a copy of each notice sent to the Borrower pursuant to section 7 of the Loan
