called the "Corporation"), for value received, hereby promises to pay
__________________________________________________, or registered assigns, the
principal sum of _________________________________________________ DOLLARS
($___________), in a single installment on August 31, 2009, or the next
preceding Business Day (as defined below) and to pay interest (computed on the
basis of a 360-day year consisting of twelve 30-day months) from the date hereof
on the unpaid principal amount hereof at the rate of 6% per annum, payable on
the last Business Day of March, June, September and December of each year (each
such day being an "Interest Payment Date") commencing on September 30, 1999,
until the principal amount hereof shall have become due and payable, whether at
maturity or by acceleration or otherwise, and thereafter at the rate of 12% per
annum on any overdue principal amount and (to the extent permitted by applicable
law) on any overdue interest until paid.

                  The payment of principal and interest on this Convertible
Debenture shall be in such currency of the United States of America as at the
time of payment shall be legal tender for payment of public and private debts.

                  For purposes of this Convertible Debenture, "Business Day"
shall mean any day other than a Saturday, Sunday or a legal holiday under the
laws of the State of New York.

                  1. CONVERTIBLE DEBENTURES. This Convertible Debenture is
issued pursuant to the Securities Purchase Agreement, dated as of August 18,
1999 (the "Purchase Agreement"),
<PAGE>   2
among the Corporation and the purchasers named therein, providing for, among
other things, the issuance of 6% Convertible Subordinated Debentures due August
31, 2009 in the aggregate principal amount of $150,000,000 (such 6% Convertible
Subordinated Debentures are referred to herein collectively as the "Convertible
Debentures").

                  2. TRANSFER OR EXCHANGE OF CONVERTIBLE DEBENTURES. The
Corporation shall keep at its office or agency maintained as provided in
subsection (a) of Section 8 a register in which the Corporation shall provide
for the registration of Convertible Debentures and for the registration of
transfer and exchange of Convertible Debentures. The holder of this Convertible
Debenture may, at its option, and either in person or by duly authorized
attorney, surrender the same for registration of transfer or exchange at the
office or agency of the Corporation maintained as provided in subsection (a) of
Section 8, and, without expense to such holder (except for taxes or governmental
charges imposed in connection therewith), receive in exchange therefor a
Convertible Debenture or Convertible Debentures in such denomination or
denominations as such holder may request, dated as of the date to which interest
has been paid on the Convertible Debenture or Convertible Debentures so
surrendered for transfer or exchange, for the same aggregate principal amount as
the then unpaid principal amount of the Convertible Debenture or Convertible
Debentures so surrendered for transfer or exchange, and registered in the name
of such person or persons as may be designated by such holder. Every Convertible
Debenture presented or surrendered for registration of transfer or exchange
shall be duly endorsed, or shall be accompanied by a written instrument of
transfer, satisfactory in form to the Corporation, duly executed by the holder
of such Convertible Debenture or his attorney, duly authorized in writing. Every
Convertible Debenture so made and delivered in exchange for this Convertible
Debenture shall in all other respects be in the same form and have the same
terms as this Convertible Debenture. No transfer or exchange of any Convertible
Debenture shall be valid unless made in the foregoing manner at such office or
agency.

                  3. LOSS, THEFT, DESTRUCTION OR MUTILATION OF CONVERTIBLE
DEBENTURE. Upon receipt of evidence satisfactory to the Corporation of the loss,
theft, destruction or mutilation of this Convertible Debenture, and, in the case
of any such loss, theft or destruction, upon receipt of an affidavit of loss
from the holder hereof reasonably satisfactory to the Corporation, or, in the
case of any such mutilation, upon surrender and cancellation of this Convertible
Debenture, the Corporation will make and deliver, in lieu of this Convertible
Debenture, a new Convertible Debenture of like tenor and unpaid principal amount
and dated as of the date to which interest has been paid on this Convertible
Debenture.

                  4. PERSONS DEEMED OWNERS; HOLDERS. The Corporation may deem
and treat the person in whose name any Convertible Debenture is registered as
the owner and holder of such Convertible Debenture for the purpose of receiving
payment of principal of and premium, if any, and interest on such Convertible
Debenture and for all other purposes whatsoever, whether or not such Convertible
Debenture shall be overdue. With respect to any Convertible Debenture at any
time outstanding, the term "holder," as used herein, shall be deemed to mean the
person in whose name such Convertible Debenture is registered as aforesaid at
such time.

                  5.  PREPAYMENTS.

                  (a) Mandatory Prepayment. Subject to the subordination
provisions of Section 14 hereof, in the event that the Corporation (i) shall
merge or consolidate with another corporation or entity (other than the
consolidation or merger of a wholly-owned subsidiary with or into the
Corporation or with or into any other wholly-owned subsidiary, and other than a
merger or consolidation involving the Corporation in which the holders of more
than 50% of the outstanding capital stock, on a fully-diluted basis, immediately
prior to such merger hold more than 50% of the outstanding capital stock of the
surviving corporation in any merger or consolidation, on a fully-diluted basis,
immediately after such merger or consolidation) or (ii) shall sell (including by
way of merger) more than 50% of the assets of the Corporation and its
subsidiaries, taken as a whole, in a single or series of related transactions,
the Corporation shall, at the option of the holder of each Convertible Debenture
then outstanding, prepay such Convertible Debenture at the principal amount
thereof, together with interest thereon to the date fixed for prepayment.

                  (b) Optional Prepayment. Upon notice given as provided in
Section 6, the Corporation may, at its option, at any time after August 31,
2001, prepay all, but not less than all, of the Convertible Debentures at the
principal amount thereof so to be prepaid, together with interest accrued
thereon to the date fixed for such prepayment.

                  (c) Non-impairment of Conversion Rights. Notwithstanding the
foregoing provisions of paragraphs (a) and (b), nothing in this Section 5 shall
impair the right of the holder hereof to convert all or any portion of this
Convertible Debenture into Common Stock in accordance with the provisions of
Section 15 hereof until such time as the amount to be prepaid by the Corporation
has been received by such holder.

                  6. NOTICE OF PREPAYMENT AND OTHER NOTICES. The Corporation
shall give written notice of prepayment of this Convertible Debenture or any
portion hereof pursuant to Section 5 not less than 15 or not more the 30 days
prior to the date fixed for such prepayment. Such notice of prepayment and all
other notices to be given to any holder of this Convertible Debenture shall be
given by registered or certified mail to the person in whose name this
Convertible Debenture is registered at its address designated on the register
maintained by the Corporation on the date of mailing such notice of prepayment
or other notice. Upon notice of prepayment being given as aforesaid, the
Corporation covenants and agrees that it will prepay, on the date therein fixed
for prepayment, this Convertible Debenture or the portion hereof, as the case
may be, so called for prepayment, at the principal amount thereof so called for
prepayment together with interest accrued thereon to the date fixed for such
prepayment.

                  7. INTEREST AFTER DATE FIXED FOR PREPAYMENT. If this
Convertible Debenture or a portion hereof is called for prepayment as herein
provided, this Convertible Debenture or such portion shall cease to bear
interest on and after the date fixed for such prepayment unless, upon
presentation for the purpose of prepayment, the Corporation shall fail to pay
this Convertible


                                       3
<PAGE>   4
Debenture or such portion, as the case may be, on such date, in which event this
Convertible Debenture or such portion, as the case may be, and, so far as may be
lawful, any overdue installment of interest thereon, shall bear interest on and
after the date fixed for such prepayment and until paid at the rate of 12% per
annum.

                  8. AFFIRMATIVE COVENANTS. The Corporation covenants and agrees
that, so long as any Convertible Debenture shall be outstanding:

                  (a) Maintenance of Office. The Corporation will maintain an
office or agency in the City of Brentwood, in the State of Tennessee (or such
other place in the United States of America as the Corporation may designate in
writing to the registered holder hereof), where the Convertible Debentures may
be presented for registration of transfer and for exchange as herein provided,
where notices and demands to or upon the Corporation in respect of the
Convertible Debentures may be served and where, at the option of the holders
thereof, the Convertible Debentures may be presented for payment. Until the
Corporation otherwise notifies the holders of the Convertible Debentures, said
office shall be the principal office of the Corporation in Brentwood, Tennessee.

                  (b) Payment of Taxes. The Corporation will promptly pay and
discharge or cause to be paid and discharged, before the same shall become in
default, all lawful taxes and assessments imposed upon the Corporation or any
subsidiary or upon the income and profits of the Corporation or any subsidiary,
or upon any property, real, personal or mixed, belonging to the Corporation or
any subsidiary, or upon any part thereof by the United States or any State
thereof, as well as all lawful claims for labor, materials and supplies, which,
if unpaid, would become a lien or charge upon such property or any part thereof;
provided, however, that the Corporation shall not be required to pay and
discharge or to cause to be paid and discharged any such tax, assessment,
charge, levy or claim (I) so long as both (x) the Corporation has set aside
adequate reserves for such tax, assessment, charge, levy or claim and (y)(i) the
Corporation shall be contesting the validity thereof in good faith by
appropriate proceedings or (ii) the Corporation shall, in its good faith
judgment, deem the validity thereof to be questionable and the party to whom
such tax, assessment, charge, levy or claim is allegedly owed shall not have
made written demand for the payment thereof or (II) where the failure to pay or
discharge would not have a material adverse effect on the Corporation and its
subsidiaries, taken as a whole (a "Material Adverse Effect").

                  (c) Corporate Existence. The Corporation will do or cause to
be done all things necessary and lawful to preserve and keep in full force and
effect its corporate existence, rights and franchises under the laws of the
United States or any State thereof or the District of Columbia; provided,
however, that nothing in this subsection (c) shall prevent (i) a consolidation
or merger of, or a sale, transfer or disposition of all or any substantial part
of the property and assets of, the Corporation, or (ii) the abandonment or
termination of any rights or franchises of the Corporation, if such abandonment
or termination is, in the good faith business judgment of


                                       4
<PAGE>   5
the Corporation, in the best interests of the Corporation or would not have a
Material Adverse Effect.

                  (d) Maintenance of Property. The Corporation will at all times
maintain and keep, or cause to be maintained and kept, in good repair, working
order and condition all significant properties of the Corporation used in the
conduct of the business of the Corporation, and will from time to time make or
cause to be made all needful and proper repairs, renewals, replacements,
betterments and improvements thereto, so that the business carried on in
connection therewith may be properly and advantageously conducted at all times;
provided, however, that nothing in this subsection (d) shall require (i) the
making of any repair or renewal or (ii) the continuance of the operation and
maintenance of any property or (iii) the retention of any assets, if such action
(or inaction) is, in the good faith business judgment of the Corporation, in the
best interests of the Corporation or would not have a Material Adverse Effect.

                  (e) Insurance. The Corporation will (i) keep adequately
insured, by financially sound and reputable insurers, all property of a
character usually insured by corporations engaged in the same or a similar
business similarly situated against loss or damage of the kinds customarily
insured against by such corporations and (ii) carry, with financially sound and
reputable insurers, such other insurance (including, without limitation,
liability insurance) in such amounts as are available at reasonable expense and
to the extent believed necessary in the good faith business judgment of the
Corporation.

                  (f) Keeping of Books. The Corporation will at all times keep
proper books of record and account in which proper entries will be made of its
transactions in accordance with generally accepted accounting principles
consistently applied.

                  (g) Notice of Default. If any one or more events which
constitute, or which with notice or lapse of time or both would constitute, an
Event of Default under Section 10 shall occur, or if the holder of any
Convertible Debenture shall demand payment or take any other action permitted
upon the occurrence of any such Event of Default, the Corporation shall
immediately after it becomes aware that any such event would with or without
notice or lapse of time or both constitute such an Event or that such demand has
been made or that any such action has been taken, give notice to the holder of
this Convertible Debenture, specifying the nature of such event or of such
demand or action, as the case may be; provided, however, that if such event, in
the good faith judgment of the Corporation, will be cured within ten Business
Days after the Corporation has knowledge that such event would, with or without
notice or lapse of time or both, constitute such an Event of Default, no such
notice need be given if such Event of Default shall be cured within such ten-day
period.

                  9. MODIFICATION BY HOLDERS; WAIVER. The Corporation may, with
the written consent of the holders of not less than 66 2/3% in principal amount
of the Convertible Debentures then outstanding, modify the terms and provisions
of the Convertible Debentures or the rights of the holders of the Convertible
Debentures or the obligations of the Corporation


                                       5
<PAGE>   6
thereunder, and the observance by the Corporation of any term or provision of
the Convertible Debentures may be waived with the written consent of the holders
of not less than 66 2/3% in principal amount of the Convertible Debentures then
outstanding; provided, however, that no such modification or waiver shall:

                  (a) change the maturity of any Convertible Debenture or reduce
         the principal amount thereof or reduce the rate or extend the time of
         payment of interest thereon or reduce the amount or change the time of
         payment of premium payable on any prepayment thereof without the
         consent of the holder of each Convertible Debenture so affected; or

                  (b) give any Convertible Debenture any preference over any
         other Convertible Debenture; or

                  (c) reduce the applicable aforesaid percentages of Convertible
         Debentures, the consent of the holders of which is required for any
         such modification.

                  Any such modification or waiver shall apply equally to all the
holders of the Convertible Debentures and shall be binding upon them, upon each
future holder of any Convertible Debenture and upon the Corporation, whether or
not such Convertible Debenture shall have been marked to indicate such
modification or waiver, but any Convertible Debenture issued thereafter shall
bear a notation referring to any such modification or waiver. Promptly after
obtaining the written consent of the holders as herein provided, the Corporation
shall transmit a copy of such modification or waiver to all the holders of the
Convertible Debentures at the time outstanding.

                  10. EVENTS OF DEFAULT. If any one or more of the following
events, herein called "Events of Default," shall occur, for any reason
whatsoever, and whether such occurrence shall, on the part of the Corporation,
be voluntary or involuntary or come about or be effected by operation of law or
pursuant to or in compliance with any judgment, decree or order of a court of
competent jurisdiction or any order, rule or regulation of any administrative or
other governmental authority and such Event of Default shall be continuing:

                  (a) default shall be made in the payment of the principal of
         any Convertible Debenture or the premium thereon, if any, when and as
         the same shall become due and payable, whether at maturity or at a date
         fixed for prepayment or by acceleration or otherwise; or

                  (b) default shall be made in the payment of any installment of
         interest on any Convertible Debenture according to its terms when and
         as the same shall become due and payable and such default shall
         continue for a period of 15 days; or

                  (c) (i) commencement of a voluntary case under the federal
         bankruptcy laws (as now or hereafter in effect), (ii) filing a petition

                                       6
<PAGE>   7
         laws, domestic or foreign, relating to bankruptcy, insolvency,
         reorganization, winding-up or composition for adjustment of debts,
         (iii) consenting to or failing to contest in a timely and appropriate
         manner any petition filed against it in an involuntary case under such
         bankruptcy laws or other laws, (iv) applying for or consenting to, or
         failing to contest in a timely and appropriate manner, the appointment
         of, or the taking of possession by, a receiver, custodian, trustee, or
         liquidator of itself or of a substantial part of its property, domestic
         or foreign, (v) admitting in writing its inability to pay its debts as
         they become due, (vi) making a general assignment for the benefit of
         creditors, or (vii) taking any corporate action for the purpose of
         authorizing any of the foregoing; or

                  (d) the entry of a decree or order by any court of competent
         jurisdiction in respect of the Corporation or any material subsidiary
         granting (i) relief in any involuntary case under the federal
         bankruptcy laws (as now or hereafter in effect) or under any other
         laws, domestic or foreign, relating to bankruptcy, insolvency,
         reorganization, winding up or adjustment of debts, or (ii) appointment
         of a trustee, receiver, custodian, liquidator or the like for the
         Corporation or any material subsidiary or for all or any substantial
         part of their respective assets, domestic or foreign, and such case or
         proceeding shall continue undismissed or unstayed for a period of 60
         consecutive days; or

                  (e) default as defined in any instrument evidencing Senior
         Obligations as defined in Section 14 hereof shall occur and as a result
         thereof the maturity of any such indebtedness shall have been
         accelerated so that the same shall have become due and payable prior to
         the date on which the same would otherwise have become due and payable
         and such acceleration shall not have been rescinded or annulled or any
         such indebtedness shall not have been paid at maturity;

then, the holder or holders of at least a majority in aggregate principal amount
of the Convertible Debentures at the time outstanding may, at its or their
option, by written notice to the Corporation, declare all the Convertible
Debentures to be, and all the Convertible Debentures shall thereupon be and
become, forthwith due and payable together with interest accrued thereon without
presentment, demand, protest or further notice of any kind, all of which are
expressly waived to the extent permitted by law; provided, however, that, upon
the occurrence and during the continuance of any of the events specified in
subsections (a) or (b) of this Section 10, the holder of any Convertible
Debenture at the time outstanding may, at its option by notice in writing to the
Corporation, declare any Convertible Debenture or Convertible Debentures then
held by it to be, and such Convertible Debenture or Convertible Debentures shall
thereupon be and become, forthwith due and payable together with interest
accrued thereon without presentment, demand, protest or further notice of any
kind, all of which are expressly waived to the extent permitted by law.
Notwithstanding the foregoing, nothing in this Section 10 shall impair the right
of the holder of this Convertible Debenture to convert all or any portion of
this Convertible Debenture into Common Stock in accordance with the provisions
of Section 15 hereof.


                                       7
<PAGE>   8
                  At any time after any declaration of acceleration has been
made as provided in this Section 10, the holders of at least 66-2/3% in
principal amount of the Convertible Debentures then outstanding may, by notice
to the Corporation, rescind such declaration and its consequences if (i) the
Corporation has paid all overdue installments of interest on the Convertible
Debentures and all principal (and premium, if any) that has become due otherwise
than by such declaration of acceleration; and (ii) all other defaults and Events
of Default (other than nonpayments of principal and interest that have become
due solely by reason of acceleration) shall have been remedied or cured or shall
have been waived pursuant to this paragraph; provided, however, that no such
rescission shall extend to or affect any subsequent default or Event of Default
or impair any right consequent thereon.

                  Without limiting the foregoing, the Corporation hereby waives
any right to trial by jury in any legal proceeding related in any way to this
Convertible Debenture or the Convertible Debentures and agrees that any such
proceeding may, if the holder so elects, be brought and enforced in the Supreme
Court of the State of New York or the United States District Court for the
Southern District of New York and the Corporation hereby waives any objection to
jurisdiction or venue in any such proceeding commenced in such court. The
Corporation further agrees that any process required to be served on it for
purposes of any such proceeding may be served on it, with the same effect as
personal service on it within the State of Delaware, by registered mail
addressed to it at its office or agency set forth in Section 19 for purposes of
notices hereunder.

                  11. SUITS FOR ENFORCEMENT. In case any one or more of the
Events of Default specified in Section 10 of this Convertible Debenture shall
happen and be continuing, the holder of this Convertible Debenture may proceed
to protect and enforce its rights by suit in equity, action at law and/or by
other appropriate proceeding, whether for the specific performance of any
covenant or agreement contained in this Convertible Debenture or in aid of the
exercise of any power granted in this Convertible Debenture, or may proceed to
enforce the payment of this Convertible Debenture or to enforce any other legal
or equitable right of the holder of this Convertible Debenture.

                  In case of any default under any Convertible Debenture, the
Corporation will pay to the holder thereof such amounts as shall be sufficient
to cover the out-of-pocket costs and expenses of such holder due to said
default, including, without limitation, collection costs and reasonable
attorneys' fees, to the extent actually incurred.

                  12. REMEDIES CUMULATIVE. No remedy herein conferred upon the
holder of this Convertible Debenture is intended to be exclusive of any other
remedy and each and every such remedy shall be cumulative and shall be in
addition to every other remedy given hereunder or now or hereafter existing at
law or in equity or by statute or otherwise.

                  13. REMEDIES NOT WAIVED. No course of dealing between the
Corporation and the holders of this Convertible Debenture or any delay on the
part of the holder hereof in


                                       8
<PAGE>   9
exercising any rights hereunder shall operate as a waiver of any right of any
holder of this Convertible Debenture.

                  14. SUBORDINATION. The Corporation covenants and agrees, and
the holder of this Convertible Debenture, by his, her or its acceptance thereof,
likewise covenants and agrees, that the indebtedness represented by this
Convertible Debenture and the payment of the principal of and interest on this
Convertible Debenture are hereby expressly made subordinate and subject in right
of payment to the prior payment in full of all Senior Obligations (as defined).
As used herein, "Senior Obligations" means the principal of (and premium, if
any) and interest on (a) all indebtedness of the Corporation (including
indebtedness of others guaranteed by the Corporation) other than the Convertible
Debentures, whether outstanding on the date of this Convertible Debenture or
thereafter created, incurred or assumed, which is (i) for money borrowed or (ii)
evidenced by a note or similar instrument given in connection with the
acquisition of any business, properties or assets of any kind, (b) any other
obligations included within the definition of "Debt" under the Indenture
relating to the Corporation's 8-3/4% Senior Subordinated Notes due November 1,
2005, whether outstanding on the date of this Convertible Debenture or
thereafter created, incurred or assumed, and (c) amendments, renewals,
extensions, modifications and refundings of any such indebtedness, unless in any
case in the instrument creating or evidencing any such indebtedness or pursuant
to which the same is outstanding it is expressly provided that such indebtedness
is not superior in right of payment to the Convertible Debentures.

                  (i) No payment or prepayment of any principal of or interest
         on account of and no repurchase, redemption or other retirement
         (whether at the option of the holder or otherwise) of, or any other
         payment of any nature with respect to this Convertible Debenture shall
         be made, if at the time of such payment, prepayment, repurchase,
         redemption or retirement or immediately after giving effect thereto (1)
         there shall exist a default in any payment with respect to any Senior
         Obligations, or (2) there shall have occurred an event of default
         (other than (A) a default in payment of the Senior Obligations or (B)
         an event of default with respect to the Senior Obligations resulting
         from a default arising under Section 10(a) or Section 10(b) hereof
         while the payment blockage contemplated by this clause (i) is in effect
         and solely as a result of such operation of this clause (i)) with
         respect to any Senior Obligations permitting the holder or holders
         thereof to require payment thereof (with notice, lapse of time, or
         both) and such event of default shall not have been cured or waived.

                  (ii) In the event of any dissolution, winding-up, liquidation,
         reorganization, arrangement, adjustment, protection, relief or
         composition of the Corporation or its debts, whether voluntary or
         involuntary or in bankruptcy, insolvency, receivership, arrangement,
         reorganization, relief or other proceedings or upon an assignment for
         the benefit of creditors or any other marshaling of the assets and
         liabilities of the Corporation or otherwise, then the holders of Senior
         Obligations shall be entitled to receive payment in full in cash of all
         Senior Obligations (including interest thereon accruing after the


                                       9
<PAGE>   10
         commencement of any such proceedings) before the holder of this
         Convertible Debenture is entitled to receive any payment on account of
         principal of, or interest upon, or any other payment of any nature with
         respect to, this Convertible Debenture, and to that end the holders of
         Senior Obligations shall be entitled to receive distributions of any
         kind or character, whether in cash or property or securities, that may
         be payable or deliverable in any such proceedings in respect of this
         Convertible Debenture, for application (in the case of cash) to or as
         collateral (in the case of non-cash property or securities) for the
         payment or prepayment of all Senior Obligations in full, after giving
         effect to any concurrent payment or distribution to the holders of such
         Senior Obligations.

                  (iii) In the event that this Convertible Debenture is declared
         due and payable before its expressed maturity because of the occurrence
         of an event of default (under circumstances when the provision of the
         foregoing paragraphs (i) or (ii) are not applicable), the holders of
         the Senior Obligations outstanding at the time that this Convertible
         Debenture becomes due and payable because of such occurrence of such an
         event of default shall be entitled to receive payment in full in cash
         of all Senior Obligations before the holder of this Convertible
         Debenture is entitled to receive any payment on account of the
         principal of or premium, if any, or interest on, or any other payment
         of any nature with respect to, this Convertible Debenture.

                  (iv) In the event that any of the events described in
         paragraphs (i), (ii) and (iii) shall occur and, notwithstanding the
         provisions of said paragraphs, any such payment or distribution of
         assets of the Corporation of any kind or character, whether in cash,
         property or securities, shall be received by the holder of this
         Convertible Debenture before all Senior Obligations are paid in full in
         cash, such payment or distribution shall be held in trust for the
         benefit of, and shall promptly be paid over or delivered to, the
         holders of such Senior Obligations or their representative or
         representatives, or to the trustee or trustees under any indenture
         pursuant to which any instruments evidencing any of such Senior
         Obligations may have been issued, as their respective interests may
         appear, for application (in the case of cash) to or as collateral (in
         the case of non-cash property or securities) for the payment or
         prepayment of all Senior Obligations remaining unpaid in full in
         accordance with their terms, after giving effect to any concurrent
         payment or distribution to the holders of such Senior Obligations.

                  (v) No holder of Senior Obligations shall be prejudiced in its
         right to enforce subordination of this Convertible Debenture by any act
         or failure to act on the part of the Corporation. The provisions of
         this Section 14 are intended to be for the benefit of, and shall be
         enforceable directly by, the holders of the Senior Obligations.

                  (vi) Any representative from time to time selected by the
         holders of the Senior Obligations (each such representative, a "Senior
         Debt Representative") is hereby irrevocably authorized and empowered
         (in its own name or in the name of the holders of this Convertible
         Debenture or otherwise), but shall have no obligation, to demand, sue


                                       10
<PAGE>   11
         for, collect and receive every payment or distribution referred to
         above in this Section 14 and give acquittance therefor and to file
         claims and proofs of claim and take such other action (including,
         without limitation, voting the indebtedness evidenced by this
         Convertible Debenture in any proceeding referred to in paragraph (ii)
         above or otherwise or enforcing any security interest or other lien
         securing payment of the indebtedness evidenced by this Convertible
         Debenture as it may deem necessary or advisable for the exercise or
         enforcement of any of the rights or interest of the holders or owners
         of the Senior Obligations or any Senior Debt Representative hereunder.

                  (vii) Each holder hereof shall duly and promptly take such
         action as any Senior Debt Representative may request (1) to collect the
         indebtedness evidenced by this Convertible Debenture for the account of
         the holders and owners of the Senior Obligations and the Senior Debt
         Representatives and to file appropriate claims or proofs of claim in
         respect of the indebtedness evidenced by this Convertible Debenture,
         (2) to execute and deliver to any Senior Debt Representative such
         powers of attorney, assignments or other instruments as it may request
         in order to enable it to enforce any and all claims with respect to,
         and any security interests and other liens securing payment of, the
         indebtedness evidenced by this Convertible Debenture, and (3) to
         collect and receive any and all payments or distributions that may be
         payable or deliverable upon or with respect to the indebtedness
         evidenced by this Convertible Debenture.

                  (viii) Each Senior Debt Representative is hereby authorized to
         demand specific performance of the provisions of this Section 14,
         whether or not the Corporation shall have complied with any of the
         provisions hereof applicable to it, at any time when the holder hereof
         shall have failed to comply with any of the provisions of this Section
         14 applicable to such holder. Each holder of this Convertible Debenture
         hereby irrevocably waives any defense based on the adequacy of a remedy
         at law that might be asserted as a bar to such remedy of specific
         performance. Each holder of this Convertible Debenture hereby
         acknowledges that the provisions of this Section 14 are intended to be
         enforceable at all times, whether before or after the commencement of a
         proceeding referred to in paragraph (ii) above.

                  (ix) Notwithstanding any other provision of this Convertible
         Debenture, until such time as the Senior Obligations shall have been
         paid in full in cash, no holder hereof may (1) ask, demand or sue for
         any payment, distribution or any other remedy in respect of the
         indebtedness evidenced hereby, (2) commence, or join with any other
         creditor (other than the holders of the Senior Obligations or any
         representative thereof) in commencing, any proceeding referred to in
         paragraph (ii) above or (3) declare any amount of the indebted ness
         evidenced hereby to be due and payable, in each case during the period
         (the "Remedy Standstill Period") lasting until the later of (i) May 22,
         2006 and (ii) one year after receipt of notice from any holder of any
         Senior Obligations or any Senior Debt Representative that the making of
         any payment with respect to this Convertible Debenture would be
         prohibited at such time by the provisions of paragraph


                                       11
<PAGE>   12
         (i) of this Section 14; provided, however, that the Remedy Standstill
         Period shall terminate automatically (a) upon the commencement of any
         proceeding referred to in paragraph (ii) above, (b) upon the
         acceleration of the maturity of the Senior Obligations or the
         institution of any foreclosure or other proceedings to enforce the
         payment of such obligations or (c) at such time as the making of any
         payment with respect to this Convertible Debenture would not be
         prohibited by the provisions of paragraph (i) of this Section 14
         (unless, in the case of (a) and (b) above, any such proceeding or
         acceleration shall be rescinded, in which event such Remedy Standstill
         Period shall automatically be reinstated as of the date of such
         rescission). Nothing contained herein shall affect the right of any
         holder of Senior Obligations or any Senior Debt Representative to give
         notice of any subsequent default under such obligations, including
         notice of the recurrence of a default previously cured or waived.

                  (x) Each holder hereof and the Corporation will, at the
         Corporation's expense and at any time and from time to time, promptly
         execute and deliver all further instruments and documents, and take all
         further action, that may be necessary or desirable, or that any
         representative of the holders of the Senior Obligations may request, in
         order to protect any right or interest granted or purported to be
         granted by the provisions of this Section 14 or to enable the holders
         of such Senior Obligations or such representative to exercise and
         enforce its rights and remedies hereunder.

                  (xi) All rights and interests under this Section 14 of the
         holders of the Senior Obligations or such representative, and all
         agreements and obligations of each of the holders hereof and the
         Corporation under this Section 14, shall remain in full force and
         effect irrespective of:

                           (1) any lack of validity or enforceability of any
                  agreement or instrument evidencing or relating to any Senior
                  Obligations;

                           (2) any change in the time, manner or place of
                  payment of, or in any other term of, or in the amount of, all
                  or any of the Senior Obligations, or any other amendment or
                  waiver of or any consent to departure from any agreement or
                  instrument evidencing or relating to any Senior Obligations;

                           (3) any exchange, release or non-perfection of any
                  collateral, or any release or amendment or waiver of or
                  consent to departure from any guaranty, for all or any of the
                  Senior Obligations; or

                           (4) any other circumstance that might otherwise
                  constitute a defense available to, or a discharge of, the
                  Corporation or a subordinated creditor.

                  (xii) The provisions of this Section 14 shall continue to be
         effective or be reinstated, as the case may be, if at any time any
         payment of any of the Senior


                                       12
<PAGE>   13
         Obligations is rescinded or must otherwise be returned by any holder of
         Senior Obligations or any Senior Debt Representative upon the
         insolvency, bankruptcy or reorganization of the Corporation or
         otherwise, all as though such payment had not been made.

                  (xiii) Each holder hereof and the Corporation hereby waive
         promptness, diligence, notice of acceptance and any other notice with
         respect to any of the Senior Obligations and this Section 14 and any
         requirement that any holder of Senior Obligations or any representative
         of such holder protect, secure, perfect or insure any security interest
         or lien on any property subject thereto or exhaust any right or take
         any action against the Corporation or any other person or entity or any
         collateral.

                  (xiv) No failure on the part of any holder of Senior
         Obligations or any representative of such holder to exercise, and no
         delay in exercising, any right hereunder shall operate as a waiver
         thereof; nor shall any single or partial exercise of any right
         hereunder preclude any other or further exercise thereof or the
         exercise of any other right. The remedies herein provided are
         cumulative and not exclusive of any remedies provided by law.

                  (xv) The provisions of this Section 14 constitute a continuing
         agreement and shall (1) remain in full force and effect until the
         Senior Obligations shall have been paid in full, (2) be binding upon
         the holders hereof and the Corporation and each of their respective
         successors and assigns, and (3) inure to the benefit of and be
         enforceable by each of the holders of Senior Obligations and their
         representatives, successors, transferees and assigns. Without limiting
         the generality of the foregoing clause (3), any holder of Senior
         Obligations may assign or otherwise transfer any note or other evidence
         of indebtedness held by it, or grant any participation in any of its
         rights or obligations under any agreement or instrument evidencing or
         relating to such Senior Obligations to any other person or entity, and
         such other person or entity shall thereupon become vested with all the
         rights in respect thereof granted to such holder herein or otherwise.

                  The provisions of this Section 14 are solely for the purpose
of defining the relative rights of the holders of Senior Obligations, on the one
hand, and each holder hereof, on the other hand, and nothing herein shall
impair, as between the Corporation and each of the holders hereof, the
obligation of this Corporation, which is unconditional and absolute, to pay the
principal of and interest hereon in accordance with their terms, nor shall
anything herein prevent each of the holders hereof from exercising all remedies
otherwise permitted by applicable law or this Convertible Debenture upon default
hereunder, subject to the rights as set forth above of holders of Senior
Obligations to receive cash, property or securities otherwise payable or
deliverable to each of the holders hereof.

                  Notwithstanding any provision contained herein to the
contrary, the indebtedness evidenced hereby shall not be subordinated to claims
of any trade creditors of the Corporation.

                  15.  CONVERSION.

                  (a) Optional Conversion. Subject to the terms and conditions
of this Section 15, the holder of this Convertible Debenture shall have the
right, at its option at any time, to convert all or any portion of the unpaid
principal amount of this Convertible Debenture into such number of fully paid
and nonassessable whole shares of Common Stock, $.01 par value, of the
Corporation ("Common Stock") as is obtained by dividing the principal amount of
this Convertible Debenture so to be converted by the conversion price of $11.25
per share or, if different, by the conversion price as last adjusted and in
effect at the date of such conversion (such price, or such price as last
adjusted, being referred to herein as the "Conversion Price"). Such right of
conversion shall be exercised by the holder hereof by giving written notice that
the holder elects to convert a stated unpaid principal amount of this
Convertible Debenture into Common Stock and by surrender of this Convertible
Debenture to the Corporation at its principal office (or such other office or
agency of the Corporation as the Corporation may designate by notice in writing
to the holder or holders of this Convertible Debenture) at any time during its
usual business hours on the date set forth in such notice, together with a
statement of the name or names (with address) in which the certificate or
certificates for shares of Common Stock shall be issued.

                  (b) Automatic Conversion. In the event that the average
closing price of the Common Stock over any 90-day period beginning on or after
August 31, 2002 exceeds 150% of the then applicable Conversion Price, then all
of the Convertible Debentures at the time issued and outstanding shall be
converted into shares of Common Stock in accordance with the terms of paragraph
(a) above, automatically and without action on the part of the holders of the
Convertible Debentures, with the same effect as if such Convertible Debentures
had been surrendered for conversion on such date by the holders thereof.

                  (c) Issuance of Certificates; Time Conversion Effected.
Promptly after (i) the receipt of the written notice referred to in paragraph
(a) above or (ii) the occurrence of the events described in paragraph (b) above,
as the case may be, and surrender of this Convertible Debenture, the Corporation
shall issue and deliver, or cause to be issued and delivered, to the holder,
registered in such name or names as such holder may direct, a certificate or
certificates for the number of whole shares of Common Stock issuable upon the
conversion of such unpaid principal amount of this Convertible Debenture. To the
extent permitted by law, such conversion shall be deemed to have been effected
and the Conversion Price shall be determined as of the close of business on the
date on which such written notice shall have been received by the Corporation
and this Convertible Debenture shall have been surrendered as aforesaid or the
last day of the 90-day period described in paragraph (b), as the case may be,
and at such time the rights of the holder of this Convertible Debenture, to the
extent of the principal amount thereof to be converted, shall cease, and the
person or persons in whose name or names any certificate or certificates for
shares of Common Stock shall be issuable upon such conversion shall be deemed to
have become the holder or holders of record of the shares represented thereby.


                                       14
<PAGE>   15
                  (d) Fractional Shares; Dividends; Partial Conversion. No
fractional shares shall be issued upon conversion of the principal amount of
this Convertible Debenture or any portion thereof, and no payment or adjustment
shall be made upon any conversion on account of any cash dividends on the Common
Stock issued upon such conversion. At the time of each conversion, the
Corporation shall pay in cash an amount equal to all interest accrued and unpaid
on the principal amount of this Convertible Debenture to be converted to the
date upon which such conversion is deemed to take place as provided in paragraph
(c) above. In case of the conversion of only a portion of the unpaid principal
amount of this Convertible Debenture, the holder hereof, at its option, may
require the Corporation to execute and deliver at the expense of the Corporation
(other than for transfer taxes, if any), upon surrender of this Convertible
Debenture, a new Convertible Debenture registered in the name of such person or
persons as may be designated by such holder for the principal amount of this
Convertible Debenture then remaining unpaid, dated as of the date to which
interest has been paid on the principal amount of this Convertible Debenture
then remaining unpaid, or may present this Convertible Debenture to the
Corporation for notation hereon of the payment of the portion of the principal
amount of this Convertible Debenture so converted. If any fractional interest in
a share of Common Stock would, except for the provisions of the first sentence
of this paragraph (d), be deliverable upon any such conversion, the Corporation,
in lieu of delivering the fractional share thereof, shall pay to the holder
surrendering this Convertible Debenture for conversion an amount in cash equal
to such fractional interest multiplied by the Conversion Price then in effect.

                  (e) Adjustment of Conversion Price upon Issuance of Common
Shares. If and whenever the Corporation shall issue or sell, or is in accordance
with subparagraphs (i) through (vii) deemed to have issued or sold, any shares
of its Common Stock for a consideration per share less than the Conversion Price
in effect immediately prior to the time of such issue or sale, then, forthwith
upon such issue or sale, the Conversion Price shall be reduced to the price
(calculated to the nearest cent) determined by dividing (x) an amount equal to
the sum of (1) the number of shares of Common Stock outstanding immediately
prior to such issue or sale (including as outstanding all shares of Common Stock
issuable upon conversion of outstanding Convertible Debentures) multiplied by
the then existing Conversion Price, and (2) the consideration, if any, received
by the Corporation upon such issue or sale, by (y) the total number of shares of
Common Stock outstanding immediately after such issue or sale (including as
outstanding all shares of Common Stock issuable upon conversion of outstanding
Convertible Debentures).

                  No adjustment of the Conversion Price, however, shall be made
in an amount less than $.01 per share, and any such lesser adjustment shall be
carried forward and shall be made at the time and together with the next
subsequent adjustment which together with any adjustments so carried forward
shall amount to $.01 per share or more.

                  For purposes of this subparagraph (e), the following
subparagraphs (i) to (vii) shall also be applicable:


                                       15
<PAGE>   16
                  (i) Issuance of Rights or Options. In case at any time the
         Corporation shall in any manner grant (whether directly or by
         assumption in a merger or otherwise) any rights to subscribe for or to
         purchase, or any options for the purchase of, Common Stock or any stock
         or securities convertible into or exchangeable for Common Stock (such
         rights or options being herein called "Options" and such convertible or
         exchangeable stock or securities being herein called "Convertible
         Securities") whether or not such Options, or the right to convert or
         exchange any such Convertible Securities are immediately exercisable,
         and the price per share for which Common Stock is issuable upon the
         exercise of such Options or upon conversion or exchange of such
         Convertible Securities (determined by dividing (x) the total amount, if
         any, received or receivable by the Corporation as consideration for the
         granting of such Options, plus the minimum aggregate amount of
         additional consideration payable to the Corporation upon the exercise
         of all such Options, plus, in the case of such Options which relate to
         Convertible Securities, the minimum aggregate amount of additional
         consideration, if any, payable upon the issue or sale of such
         Convertible Securities and upon the conversion or exchange thereof, by
         (y) the total maximum number of shares of Common Stock issuable upon
         the exercise of such Options or upon the conversion or exchange of all
         such Convertible Securities issuable upon the exercise of such Options)
         shall be less than the Conversion Price in effect immediately prior to
         the time of the granting of such Options, then the total maximum number
         of shares of Common Stock issuable upon the exercise of such Options or
         upon conversion or exchange of the total maximum amount of such
         Convertible Securities issuable upon the exercise of such Options shall
         be deemed to have been issued for such price per share as of the date
         of granting of such Options and thereafter shall be deemed to be
         outstanding. Except as otherwise provided in subparagraph (iii), no
         adjustment of the Conversion Price shall be made upon the actual issue
         of such Common Stock or of such Convertible Securities upon exercise of
         such Options or upon the actual issue of such Common Stock upon
         conversion or exchange of such Convertible Securities. If at the end of
         the period during which such Options or Convertible Securities are
         exercisable not all Options or Convertible Securities shall have been
         exercised or converted, the adjusted Conversion Price shall be
         immediately readjusted to what it would have been based upon the number
         of additional shares of Common Stock actually issued in respect of such
         Options and Convertible Securities.

                  (ii) Issuance of Convertible Securities. In case the
         Corporation shall in any manner issue (whether directly or by
         assumption in a merger or otherwise) or sell any Convertible
         Securities, whether or not the rights to exchange or convert thereunder
         are immediately exercisable, and the price per share for which Common
         Stock is issuable upon such conversion or exchange (determined by
         dividing (x) the total amount received or receivable by the Corporation
         as consideration for the issue or sale of such Convertible Securities,
         plus the minimum aggregate amount of additional consideration, if any,
         payable to the Corporation upon the conversion or exchange thereof, by
         (y) the total maximum number of shares of Common Stock issuable upon
         the conversion or exchange of all such Convertible Securities) shall be
         less than the Conversion Price in effect

         immediately prior to the time of such issue or sale, then the total
         maximum number of shares of Common Stock issuable upon conversion or
         exchange of all such Convertible Securities shall be deemed to have
         been issued for such price per share as of the date of the issue or
         sale of such Convertible Securities and thereafter shall be deemed to
         be outstanding, provided that (1) except as otherwise provided in
         subparagraph (iii) below, no adjustment of the Conversion Price shall
         be made upon the actual issue of such Common Stock upon conversion or
         exchange of such Convertible Securities and (2) if any such issue or
         sale of such Convertible Securities is made upon exercise of any Option
         to purchase any such Convertible Securities for which adjustments of
         the Conversion Price have been or are to be made pursuant to other
         provisions of this paragraph (e), no further adjustment of the
         Conversion Price shall be made by reason of such issue or sale. If at
         the end of the period during which such Convertible Securities are
         convertible not all Convertible Securities shall have been converted,
         the adjusted Conversion Price shall be immediately readjusted to what
         it would have been based upon the number of additional shares of Common
         Stock actually issued in respect of such Convertible Securities.

                  (iii) Change in Option Price or Conversion Rate. Upon the
         happening of any of the following events, namely, if the purchase price
         provided for in any Option referred to in subparagraph (i), the
         additional consideration, if any, payable upon the conversion or
         exchange of any Convertible Securities referred to in subparagraph (i)
         or (ii), or the rate at which any Convertible Securities referred to in
         subparagraph (i) or (ii) are convertible into or exchangeable for
         Common Stock shall change at any time (other than under or by reason of
         provisions designed to protect against dilution), the Conversion Price
         in effect at the time of such event shall forthwith be readjusted to
         the Conversion Price which would have been in effect at such time had
         such Options or Convertible Securities still outstanding provided for
         such changed purchase price, additional consideration or conversion
         rate, as the case may be, at the time initially granted, issued or
         sold; and on the expiration of any such Option or termination of any
         such right to convert or exchange such Convertible Securities, the
         Conversion Price then in effect hereunder shall forthwith be increased
         to the Conversion Price which would have been in effect at the time of
         such expiration or termination had such Option or Convertible
         Securities, to the extent outstanding immediately prior to such
         expiration or termination, never been issued, and the Common Stock
         issuable thereunder shall no longer be deemed to be outstanding. If the
         purchase price provided for in any such Option referred to in
         subparagraph (i) or the rate at which any Convertible Securities
         referred to in subparagraph (i) or (ii) are convertible into or
         exchangeable for Common Stock shall be reduced at any time under or by
         reason of provisions with respect thereto designed to protect against
         dilution, then, in case of the delivery of Common Stock upon the
         exercise of any such Option or upon conversion or exchange of any such
         Convertible Securities, the Conversion Price then in effect hereunder
         shall forthwith be adjusted to such respective amount as would have
         been obtained had such Option or Convertible Securities never been
         issued as to such Common Stock and had adjustments been made upon the
         issuance of the shares of


                                       17
<PAGE>   18
         Common Stock delivered as aforesaid, but only if as a result of such
         adjustment the Conversion Price then in effect hereunder is thereby
         reduced.

                  (iv) Stock Dividends. Without duplication of the adjustment
         contemplated by clause (f) below, in case the Corporation shall declare
         a dividend or make any other distribution upon any stock of the
         Corporation payable in Common Stock, Options or Convertible Securities,
         any Common Stock, Options or Convertible Securities, as the case may
         be, issuable in payment of such dividend or distribution shall be
         deemed to have been issued or sold without consideration.

                  (v) Consideration for Stock. In case any shares of Common
         Stock, Options or Convertible Securities shall be issued or sold for
         cash, the consideration received therefor shall be deemed to be the
         amount received by the Corporation therefor, without deduction
         therefrom of any expenses incurred or any underwriting commissions or
         concessions paid or allowed by the Corporation in connection therewith.
         In case any shares of Common Stock, Options or Convertible Securities
         shall be issued or sold for a consideration other than cash, the amount
         of the consideration other than cash received by the Corporation shall
         be deemed to be the fair value of such consideration as determined in
         good faith by the Board of Directors of the Corporation, without
         deduction of any expenses incurred or any underwriting commissions or
         concessions paid or allowed by the Corporation in connection therewith.
         In case any Options shall be issued in connection with the issue and
         sale of other securities of the Corporation, together compromising one
         integral transaction in which no specific consideration is allocated to
         such Options by the parties thereto, such Options shall be deemed to
         have been issued without consideration.

                  (vi) Record Date. In case the Corporation shall take a record
         of the holders of its Common Stock for the purpose of entitling them
         (x) to receive a dividend or other distribution payable in Common
         Stock, Options or Convertible Securities, or (y) to subscribe for or
         purchase Common Stock, Options or Convertible Securities, then such
         record date shall be deemed to be the date of the issue or sale of the
         shares of Common Stock deemed to have been issued or sold upon the
         declaration of such dividend or the making of such other distribution
         or the date of the granting of such right of subscription or purchase,
         as the case may be.

                  (vii) Treasury Shares. The number of shares of Common Stock
         outstanding at any given time shall not include shares owned or held by
         or for the account of the Corporation, and the disposition of any such
         shares shall be considered an issue or sale of Common Stock for the
         purposes of this paragraph (e).

                  (f) Subdivision or Combination of Stock. Without duplication
of the adjustment contemplated by clause (iv) of paragraph (e), in case the
Corporation shall at any time declare a dividend or make any other distribution
upon any stock of the Corporation payable in Common Stock or subdivide its
outstanding shares of Common Stock into a greater number of shares, the


                                       18
<PAGE>   19
Conversion Price in effect immediately prior to such subdivision shall be
proportionately reduced, and conversely, in case the outstanding shares of
Common Stock of the Corporation shall be combined into a smaller number of
shares, the Conversion Price in effect immediately prior to such combination
shall be proportionately increased.

                  (g) Certain Issues of Stock Excepted. Anything herein to the
contrary notwithstanding, the Corporation shall not make any adjustment of the
Conversion Price in the case of (i) the issuance of shares of Common Stock upon
conversion of Convertible Debentures; (ii) the issuance of Options or shares of
Common Stock to employees, directors or consultants of the Corporation or its
subsidiaries, either directly or pursuant to Options, pursuant to plans or
arrangements approved by the Board of Directors (or Compensation Committee
thereof) of the Corporation; (iii) the issuance of shares of Common Stock in
respect of any Convertible Securities or Options issued by the Corporation prior
to the date of this Convertible Debenture; or (iv) the issuance of shares of
Common Stock in connection with any acquisition, merger, consolidation, or other
business combination transaction.

                  (h) Reorganization or Reclassification. If any capital
reorganization or reclassification of the capital stock of the Corporation shall
be effected in such a way that holders of Common Stock shall be entitled to
receive stock, securities or assets with respect to or in exchange for Common
Stock, then, as a condition of such reorganization or reclassification, lawful
and adequate provisions shall be made whereby each holder of a Convertible
Debenture shall thereafter have the right to receive, upon the basis and upon
the terms and conditions specified herein and in lieu of the shares of Common
Stock of the Corporation immediately theretofore receivable upon the conversion
of such shares of stock, securities or assets as may be issued or payable with
respect to or in exchange for a number of outstanding shares of such Common
Stock equal to the number of shares of such stock immediately theretofore so
receivable had such reorganization or reclassification not taken place, and in
any such case appropriate provision shall be made with respect to the rights and
interests of such holder to the end that the provisions hereof (including
without limitation provisions for adjustments of the Conversion Price) shall
thereafter be applicable, as nearly as may be, in relation to any shares of
stock, securities or assets thereafter deliverable upon the exercise of such
conversion rights (including an immediate adjustment, by reason of such
reorganization or reclassification, of the Conversion Price to the value for the
Common Stock reflected by the terms of such reorganization or reclassification
if the value so reflected is less than the Conversion Price in effect
immediately prior to such reorganization or reclassification). In the event of a
merger or consolidation of the Corporation as a result of which a greater or
lesser number of shares of Common Stock of the surviving corporation are
issuable to holders of Common Stock of the Corporation outstanding immediately
prior to such merger or consolidation, the Conversion Price in effect
immediately prior to such merger or consolidation shall be adjusted in the same
manner as though there were a subdivision or combination of the outstanding
shares of Common Stock of the Corporation. The Corporation will not effect any
such consolidation, merger, or any sale of all or substantially all of its
assets or properties, unless prior to the consummation thereof the successor
corporation or other entity (if other than the Corporation) resulting from such
consolidation or merger or the


                                       19
<PAGE>   20
corporation purchasing such assets shall assume, by written instrument executed
and mailed or delivered to each holder of Convertible Debentures at the last
address of such holder appearing on the books of the Corporation, the obligation
to deliver to such holder such shares of stock, securities or assets as, in
accordance with the foregoing provisions, such holder may be entitled to
receive.

                  (i) Notice of Adjustment. Upon any adjustment of the
Conversion Price, then and in each such case the Corporation shall give written
notice thereof, by first class mail, postage prepaid, addressed to each holder
of Convertible Debenture at the address of such holder as set forth in the
register maintained by the Corporation for the registration of transfer and
exchange of Convertible Debentures, which notice shall state the Conversion
Price resulting from such adjustment, setting forth in reasonable detail the
method of calculation and the facts upon which such calculation is based.

                  (j) Other Notices. In case at any time:

                  (i) the Corporation shall declare any dividend upon its Common
         Stock payable in cash or stock or make any other distribution to the
         holders of its Common Stock;

                  (ii) the Corporation shall offer for subscription pro rata to
         the holders of its Common Stock any additional shares of stock of any
         class or other rights;

                  (iii) there shall be any capital reorganization or
         reclassification of the capital stock of the Corporation, or a
         consolidation or merger of the Corporation with, or a sale of all or
         substantially all its assets to, another corporation or other entity;
         or

                  (iv) there shall be a voluntary or involuntary dissolution,
         liquidation or winding-up of the Corporation;

then, in any one or more of said cases, the Corporation shall give, by first
class mail, postage prepaid, addressed to each holder of Convertible Debentures
at the address of such holder as set forth in the register maintained by the
Corporation for the registration of transfer and exchange of Convertible
Debentures, (A) at least 20 days' prior written notice of the date on which the
books of the Corporation shall close or a record shall be taken for such
dividend, distribution or subscription rights or for determining rights to vote
in respect of any such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding up, and (B) in the case of any such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding up, at least 20 days' prior written notice of the date
when the same shall take place. Such notice in accordance with the foregoing
clause (A) shall also specify, in the case of any such dividend, distribution or
subscription rights, the date on which the holders of Common Stock shall be
entitled thereto, and such notice in accordance with the foregoing clause (B)
shall also specify the date on which the holders of Common Stock shall be
entitled to exchange their Common Stock for securities or other property
deliverable upon such reorganization,


                                       20
<PAGE>   21
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up, as the case may be.

                  (k) Stock to Be Reserved. The Corporation will at all times
reserve and keep available out of its authorized Common Stock or its treasury
shares, solely for the purpose of issue upon the conversion of the Convertible
Debentures as herein provided, such number of shares of Common Stock as shall
then be issuable upon the conversion of the unpaid principal amount of all
outstanding Convertible Debentures. The Corporation covenants that all shares of
Common Stock which shall be so issued shall be duly and validly issued and fully
paid and nonassessable and free from all taxes, liens and charges with respect
to the issue thereof, and, without limiting the generality of the foregoing, the
Corporation covenants that it will from time to time take all such action within
its control as may be requisite to assure that the par value per share of the
Common Stock is at all times equal to or less than the effective Conversion
Price. The Corporation will take all such action as may be necessary to assure
that all such shares of Common Stock may be so issued without violation of any
applicable law or regulation, or of any requirements of any national securities
exchange upon which the Common Stock of the Corporation may be listed. The
Corporation will not take any action which results in any adjustment of the
Conversion Price if the total number of shares of Common Stock issued and
issuable after such action upon conversion of the Convertible Debentures would
exceed the total number of shares of Common Stock then authorized by the
Corporation's Certificate of Incorporation.

                  (l) Issue Tax. The issuance of certificates for shares of
Common Stock upon conversion of the Convertible Debentures shall be made without
charge to the holders thereof for any issuance tax in respect thereof, provided
that the Corporation shall not be required to pay any tax which may be payable
in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than that of the holder of the Convertible Debenture
the principal amount of which is being converted.

                  (m) Closing of Books. The Corporation will at no time close
its transfer books against the transfer of any Convertible Debenture or of any
shares of Common Stock issued or issuable upon the conversion of any Convertible
Debenture in any manner which interferes with the timely conversion of such
Convertible Debenture.

                  (n) Definition of Common Stock. As used in this Section 15,
the term "Common Stock" shall mean and include the Corporation's authorized
Common Stock, $.01 par value, as constituted on August 31, 1999, and shall also
include any capital stock of any class of the Corporation thereafter authorized
which shall not be limited to a fixed sum or percentage of par value in respect
of the rights of the holders thereof to participate in dividends or in the
distribution of assets upon the voluntary or involuntary liquidation,
dissolution or winding up of the Corporation.
