of any event to Debentureholders when such notice is required to be given

nominal date.

an original, but all such counterparts shall together constitute but one and the
same document.

hereby appointed "Debenture Registrar" for the purpose of registering Debentures
and effecting transfers of Debentures as herein provided.

                  b. Upon surrender for transfer of any Debenture at the office

evidence to its satisfaction of the destruction, loss or theft of any Debenture
and (ii) such security or indemnity as may be required by it to save the Company
harmless, then, in the absence of notice to the Debenture Registrar that such
Debenture has been acquired by a bona fide purchaser, the Debenture Registrar
shall execute and deliver in lieu of any such destroyed, lost or stolen
Debenture, a new Debenture of like tenor and principal amount, bearing a number
not contemporaneously outstanding.

                  c. In case any such mutilated, destroyed, lost or stolen
Debenture has become or is about to become due and payable, or has been called

the Debenture Registrar may require the payment of a sum sufficient to cover any
tax or other governmental charge

therewith.

lost or stolen Debenture shall be at any time enforceable by anyone, and shall
be entitled to all the benefits of this Agreement equally and proportionately
with any and all other Debentures duly issued hereunder.

                  f. The provisions of this Section are exclusive and shall

Debenture shall (subject to Section 2.1.) carry all of the rights to interest

will duly and punctually pay the principal of and interest on the Debentures in
accordance with the terms of the Debentures and this Agreement.

                  b. Maintenance of Office. The Company will maintain an office
in the Place of Payment where Debentures may be presented or surrendered for
Payment, where Debentures may be presented or surrendered for transfer, exchange

interest of the Debentures shall be payable. The Company will give prompt
written notice of the location, and of any change in the location, of such

Company will, on or before each due date of the principal of or interest on any
of the Debentures, segregate and hold in trust for the benefit of the Holders of

herein provided. Any money then held by the Company, in trust for the payment of
the principal of or interest on any Debenture and remaining unclaimed for six
years after such principal or interest has become due and payable shall be paid
to the Company on Company request, or (if then held by the Company) shall be
discharged from such trust; and the holder of such Debenture shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Company as trustee of such trust money, shall thereupon
cease; provided, that, before making any such repayment, the Company shall send
notice to the persons entitled to such unclaimed money at their last address
appearing on the Debenture Register, unless previous communications forwarded to
such addresses have been returned unclaimed.

                  d. Payment of Taxes and Other Claims. The Company will pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent, (i) all taxes, assessments and governmental charges levied or
imposed upon it or upon its income, profits or property and (ii) all lawful
charges for labor, materials and supplies which, if unpaid, might by law become
a lien upon its property; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

                  e. Maintenance of Properties. The Company will cause all the
properties of the Company and of any Subsidiary, used or useful in the conduct
of the business of the Company or of

such Subsidiary, to be maintained and kept in good condition, repair and working
order and supplied with all necessary equipment and will cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof,
all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly and advantageously conducted
at all times; provided, however, that nothing in this Section shall prevent the
Company or any Subsidiary from discontinuing the operation and maintenance of
any of its properties if such discontinuance is, in the judgment of the Company
or such Subsidiary, respectively, desirable in the conduct of its business and
not disadvantageous in any material respect to the Debentureholders.

                  f. Corporate Existence. The Company will do or cause to be
done all things necessary to preserve and keep in full force and effect its
corporate existence, rights (charter and statutory) and franchises; provided,
however, that the Company shall not be required to preserve any right or
franchise if the Board of Directors shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Company,
and that the loss thereof is not disadvantageous in any material respect to the
Debentureholders.

                  g. Insurance. The Company will insure and keep insured, and
will cause each of its Subsidiaries to insure and keep insured, to a reasonable
amount with reputable insurance companies, so long as any of the Debentures
shall be outstanding, all property of a character usually insured by
corporations engaged in the same or a similar business against loss or damage of
the kinds customarily insured against by such corporations (including without
limitation against all tort or product liability claims) and carry, and cause
each of its Subsidiaries to carry, such other insurance, all in such amounts and
against such risks, as is usually carried by corporations engaged in the same or
a similar business or owning similar properties.

                  h. Authorization. The Company has the right and power and is
duly authorized and empowered to enter into, execute, deliver and perform the
Debentures, this Agreement and the Other Agreements executed concurrently
herewith. The execution, delivery and/or performance by the Company of the
Debentures, this Agreement and the other Agreements shall not, by the lapse of
time, the giving of notice or otherwise, constitute a violation of any
applicable law or a breach of any provision contained in the Articles of
Incorporation or Bylaws of the Company or contained in any agreement, instrument
or document to which the Company is now a party or by which it is otherwise
bound.

         Section 5.2. Negative Covenants. Without the Debentureholders' prior

discretion, give concurrently herewith or hereinafter, the Company covenants

the Debentureholders and their counsel) subordination agreements subordinating
their claims against the Company to the payment of the Liabilities.

                  e. Make any substantial change in the nature or scope of or
discontinue or dispose of any part of the Company's business.

         Section 5.3. Contesting Charges. Notwithstanding anything to the
contrary herein, the Company may dispute any Charges without prior payment
thereof, even if such non-payment may cause a lien to attach to the assets of
the Company, provided that the Company shall have given the Debentureholders
written notice of said dispute and shall be diligently contesting the same in
good faith in an appropriate proceeding and, provided further that, if the same
are in excess of $10,000 in the aggregate at any time or times hereinafter, the
Company has given the Debentureholders such additional collateral and assurances
that the Debentureholders, in their sole discretion, deems necessary under the
circumstances.

         Section 5.4. Payment of Charges. Subject to the provisions of Section
5.3 immediately above, the Company shall pay promptly when due all of the

Company shall so advise the Debentureholders thereof in writing and the
Debentureholders may, without waiving or releasing any obligation or liability
of the Company hereunder or any Event of Default, in their sole discretion, at
any time or times thereafter, make such payment, or any part thereof, or obtain
such discharge and take any other action with respect thereto which the
Debentureholders deem advisable. All sums so paid by the Debentureholders and
any expenses, including reasonable attorneys' fees, court costs, expenses and
other charges relating thereto, shall be payable, upon demand, by the Company to

the Collateral.

insurance and evidence of payment of all premiums therefor.

all sums required to be paid under the foregoing paragraphs a., b. and c., shall

right to institute any proceeding, judicial or otherwise, with respect to this
Agreement, or for the appointment of a receiver or trustee, or for any other

notice of a continuing Event of Default; it being understood and intended than
no one or more Debentureholders shall have any right in any manner whatever by
virtue of, or by availing of, any provision of this Agreement to affect, disturb
or prejudice the rights of any other Debentureholder, or to obtain or to seek to
obtain priority or preference over any other Debentureholder or to enforce any
right under this Agreement, except in the manner herein provided and for the
equal and ratable benefit of the Debentureholders.

         Section 6.6. Unconditional Right of Debentureholders to Receive
Principal and Interest. Notwithstanding any other provision in this Agreement
(but subject to Section 2.1.), the Holder of any Debenture shall have the right
which is absolute and unconditional to receive payment of the principal of and
interest on such Debenture on the respective Stated Maturities expressed in such
Debenture (or, in the case of redemption pursuant to Article Seven or Eight, on
the Redemption Date subject to the




<PAGE>   20
limitations of Article Seven or Eight) and to institute suit for the enforcement
of any such payment, and such right shall not be impaired without the consent of
such Holder.

         Section 6.7. Restoration of Rights and Remedies. If any Debentureholder
has instituted any proceeding to enforce any right or remedy under this
Agreement and such proceeding has been discontinued or abandoned for any reason,
or has been determined adversely to such Debentureholder, then and in every such
case the Company and the Debentureholders shall, subject to any determination in
such proceeding, be restored severally and respectively to their former
positions hereunder, and thereafter all rights and remedies of the
Debentureholders shall continue as though no such proceeding had been
instituted.

         Section 6.8. Rights and Remedies Cumulative. No right or remedy herein
conferred upon or reserved to the Debentureholders is intended to be exclusive
of any other right or remedy, and every right and remedy shall, to the extent
permitted by law, be cumulative and in addition to every other right and remedy
given hereunder or now or hereinafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise,
shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

         Section 6.9. Delay or Omission Not Waiver. No delay or omission of any
Debentureholder to exercise any right or remedy accruing upon any Event of
Default shall impair any such right or remedy or constitute a waiver of any such
Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Debentureholders may be exercised from time to
time, and as often as may be deemed expedient by the Debentureholders.

         Section 6.10. Waiver of Past Defaults. The Holders of the Debentures
may waive any past default hereunder and its consequences, except a default

                  a. In the payment of the principal of or interest on any
Debenture, or

                  b. In respect of a covenant or provision hereof which cannot
be modified or amended without the consent of the Holder of each Debenture
affected.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Agreement; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

         Section 6.11. Undertaking for Costs. All parties to this Agreement
agree, and each Debentureholder by his acceptance thereof shall be deemed to
have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Agreement, or in any suit against
the Company for any action taken or omitted by it, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by any Debentureholder(s), or to any suit
instituted by any Debentureholder(s) for the enforcement of the payment of the
principal or interest on any Debenture on or after the respective Stated
Maturities




<PAGE>   21
expressed in such Debenture for such principal or interest (or, in the case of
redemption, on or after the Redemption Date).

         Section 6.12. Waiver of Stay or Extension Laws. The Company covenants
(to the extent that it may lawfully do so) that it will not at any time insist
upon, or plead, or in any manner whatsoever claim or take the benefit or
advantage of, any stay or extension law wherever enacted, now or at any time
hereinafter in force, which may affect the covenants or the performance of this
Agreement; and the Company (to the extent that it may lawfully do so) hereby
expressly waives all benefits or advantage of any such law, and covenants that
it will not hinder, delay or impede the execution of any power herein granted to
the Company, but will suffer and permit the execution of every such power as
though no such law had been enacted.

         Section 6.13. Secured Creditor Status. If an Event of Default occurs
and is continuing, than and in every such case the Debentureholders shall have
all of the following rights and remedies;

                  a. All of the rights and remedies of a secured party under the
Uniform Commercial Code of the state where such rights and remedies are
asserted, or under other applicable law, all of which rights and remedies shall
be cumulative, and none exclusive, to the extent permitted by law, in addition
to any other rights and remedies contained in this Agreement and in all of the
Other Agreements.

                  b. The right to (i) enter upon the premises of the Company,
without any obligation to pay rent to the Company, through self-help and without
judicial process, without first obtaining a final judgment or giving the Company
notice and opportunity for a hearing on the validity of the Debentureholders'
claim and without any obligation to pay rent to the Company, or any other place
or places where the Collateral is located and kept, and remove the Collateral
therefrom to the premises of the Debentureholders or any agent of the
Debentureholders, for such time as the Debentureholders may desire, in order to
effectively collect or liquidate the Collateral and/or (ii) require the Company
to assemble the Collateral and make it available to the Debentureholders at a
place to be designated by the Debentureholders, in their sole discretion.

                  c. The right to sell or to otherwise dispose of all or any
Collateral in its then condition, or after any further manufacturing or
processing thereof, at public or private sale or sales, without such notice as
may be required by law, in lost or in bulk, for cash or on credit, all as the
Debentureholders, in their sole discretion may deem advisable; such sales may be
adjourned from time to time with or without notice. The Debentureholders hall
have the right to conduct such sales on the premises of the Company or elsewhere
and shall have the right to use such premises without charge for such sales for
such time or times as the Debentureholders may see fit. The Debentureholders are
hereby granted a license or other right to use, without charge, the Company's
labels, patents, copyrights, rights of use of any name, trade secrets, trade
names, trademarks and advertising matter, or any property of a similar nature,
as it pertains to the Collateral, in advertising for sale and selling and
Collateral and the Company's rights under all licenses and all franchise
agreements shall inure to the Company's benefit. The Debentureholders shall have
the right to sell, lease or otherwise dispose of the Collateral, or any part
thereof, for cash, credit or any combination thereof, the Debentureholders may
purchase all or any part of the collateral at public or, if permitted by law,
private sale and, in lieu of actual payment of such purchase price, may set off
the amount of such price against the Liabilities. The proceeds realized from the
sale of any Collateral shall be applied first to the reasonable costs,




<PAGE>   22
expenses and attorneys' fees and expenses incurred by the Company for collection
and for acquisition, completion, protection, removal, storage, sale and delivery
of the Collateral; second to interest due upon any of the Liabilities; and third
to the principal of the Liabilities. If any deficiency shall arise, the Company
shall remain liable to the Debentureholders therefor.

         d. Notice. Any notice required to be given by the Debentureholders of a
sale, lease other disposition of the Collateral or any other intended action by
the Debentureholders, deposited in the United States mail, postage prepaid and
duly addressed to the Company ten (10) days prior to such proposed action, shall
constitute commercially reasonable and fair notice to the Company.

         e. Appointment of Debentureholders as Company's Lawful Attorney. Upon
and after an Event of Default, the Company irrevocably designates, makes,
constitutes and appoints the Debentureholders (and all persons designated by the
Debentureholders) as the Company's true and lawful attorney (and agent-in-fact)
and the Debentureholders, or the Debentureholders' agent, may, without notice to
the Company, and at such time or times thereafter as the Debentureholders or
said agent, in their sole discretion, may determine, in the Debentureholders' or
