ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

        On July 24, 1998, Noble International, Ltd. (the "Company") consummated
the acquisition, through its wholly-owned subsidiary Noble Canada Holdings,
Ltd., a Nova Scotia corporation ("NCH"), and NCH's wholly-owned subsidiary Noble
Canada, Inc., an Ontario corporation ("Noble Canada"), of all of the outstanding
capital stock of Tiercon Holdings, Inc., an Ontario corporation ("Tiercon"),
including Tiercon's wholly-owned subsidiary Triam Automotive Canada, Inc., an
Ontario corporation ("Triam"). The aggregate consideration paid for the
acquisitions of Tiercon and Triam (collectively, the "Tiercon/Triam
Acquisition") consisted of approximately $32 million in cash and 80,000 shares
of Noble Canada's Class T Non-Voting Exchangeable Preferred Shares, which are
exchangeable for 80,000 shares of the Company's common stock, no par value
("Common Stock"). The cash portion of the Tiercon/Triam purchase price was
funded from the Company's line of credit with Comerica Bank (which was
subsequently reduced using proceeds from the Company's private offering of
debentures as described under Item 9 below).

        Triam is a Tier II supplier of injection molded plastic components to
the automotive industry. Triam's primary products are painted exterior body trim
components, such as rocker panels and body side moldings. For each of 1996 and
1997, Triam was named "Supplier of the Year" for exterior moldings by General
Motors Corporation ("GM"), placing Triam among the top 300 of GM's global
suppliers. Triam currently operates two leased facilities with an aggregate of
approximately 197,000 square feet in Stoney Creek, Ontario, Canada and has
approximately 255 employees. Triam operates approximately 24 high pressure
injection molding machines ranging in capacity from 80 tons to 3,300 tons.

ITEM 5.  OTHER EVENTS.

        Effective August 1, 1998, in connection with planned operational
changes, Christopher L. Morin resigned as a member of the Company's Board of
Directors and as Chief Operating Officer in order to assume a new position as
Chief Executive Officer of Noble Metal Technologies, Inc., the Company's
wholly-owned subsidiary. The vacancy left by Mr. Morin's resignation was filled
by the appointment of Lloyd P. Jones, III, the Company's President.

ITEM 9.  SALES OF EQUITY SECURITIES PURSUANT TO REGULATION S.

        The Company has offered, and will continue to offer for sale (the
"Offering") until August 31, 1998, subject to extension to September 15, 1998,
to persons who are not "United States persons" as that term is defined in Rule
902 of Regulation S promulgated under the Securities Act of 1933, as amended
(the "Act"), up to an aggregate of $40 million principal amount of 6%
Convertible Subordinated Debentures due 2005 (the "Debentures"). Initial
closings of the Offering 


                                       3
<PAGE>   4

were held on July 31 and August 10, 1998 resulting in gross proceeds to the
Company of $15.5 million and $5.25 million, respectively. The Debentures are
listed on Luxembourg Stock Exchange. BlueStone Capital Partners, L.P. and Robert
Fleming & Co. Limited, as placement agents, have and will receive fees equal to
6% of the gross proceeds of the Offering.

        The Debentures have and will be issued under an Indenture dated as of
July 23, 1998 (the "Indenture"), between the Company and American Stock Transfer
& Trust Company, as trustee (the "Trustee"). The Debentures are unsecured,
subordinated obligations of the Company limited (except for the PIK Debentures,
as defined below) to $40 million aggregate principal amount, and will mature on
July 31, 2005 (the "Maturity Date"). The Debentures bear interest at the rate of
6% per annum, payable semi-annually in arrears on January 31 and July 31 of each
year (each an "Interest Payment Date"), commencing January 31, 1999, subject to
increases in such interest rate based upon failure of the Company to comply with
certain covenants contained in the Registration Rights Agreement (as defined
below) until such covenants have been complied with, and at the rate of 10% per
annum on any overdue principal and (to the extent permitted by applicable law)
on any overdue interest, until paid in full. Interest on the Debentures accrues
from July 31, 1998 or from the most recent Interest Payment Date to which
interest has been paid or duly provided for. Interest is computed on the basis
of a 360-day year of twelve 30-day months. During the PIK Payment Period (the
36-month period expiring on July 31, 2001), the Company will issue to the
appropriate holders of the Debentures on each Interest Payment Date, by giving
notice to the Trustee to authenticate for original issue, PIK ("payment in
kind") Debentures, in lieu of cash interest, in integral multiples of $1,000 and
in an aggregate principal amount equal to the amount of cash interest that would
otherwise be paid to such holders on such Interest Payment Date. Each PIK
Debenture will be identical to, and immediately fungible with, the Debentures
originally issued in sales pursuant to the Offering. Each issuance of PIK
Debentures will be made pro rata with respect to the outstanding Debentures,
subject to the payments of cash in lieu of fractional PIK Debentures in the
event that any such payment of interest in PIK Debentures would result in the
issuance of a PIK Debenture which is less than $1,000 or an integral multiple of
$1,000. If the Company shall default in issuing any PIK Debentures on an
Interest Payment Date, the amount of interest evidenced thereby shall thereafter
be payable in cash. The Debentures have and will be sold in denominations of
$100,000 and integral multiples of $10,000 at a price equal to 100% of the
principal amount thereof plus accrued interest thereon, if any, from July 31,
1998, but are immediately transferrable (in book entry form only except in
limited circumstances) in principal denominations of $1,000 or integral
multiples thereof.

        The Debentures are subordinated in right of payment to the prior payment
in full of all existing and future Senior Indebtedness (as hereinafter defined)
of the Company. The term "Senior Indebtedness" includes all present and future
obligations incurred by the Company and/or any of its subsidiaries under any
loan or credit agreement with a bank or other institutional lender, under any
guarantee of such obligations, to finance the acquisition of capital assets, for
indebtedness to sellers in connection with the acquisition of businesses and
under capitalized leases.

        The Debentures are convertible into shares of Common Stock at $14.3125
per share (the "Conversion Price"), subject to adjustment upon the occurrence of
certain events, at any time commencing November 30, 1998 and prior to the close
of business on the Maturity Date, unless previously redeemed or repurchased.
Pursuant to a separate agreement (the "Registration Rights 


                                       4
<PAGE>   5

Agreement"), the Company has agreed, for the benefit of the holders of the
Debentures, that it will, at its cost, file a shelf registration statement (the
"Shelf Registration Statement") with the Securities and Exchange Commission (the
"Commission") with respect to resales of the shares of Common Stock issued or
issuable upon conversion of the Debentures by November 30, 1998. The
Registration Rights Agreement also provides that the Company will use its best
efforts to have such Shelf Registration Statement declared effective by the
Commission as soon as possible, and in no event later than January 31, 1999.
Further, the Company is required to use its best efforts to maintain such Shelf
Registration Statement continuously effective under the Act for a period of two
years from the final closing date of the Offering or a shorter period, which
will terminate when all of the shares of Common Stock issued upon conversion of
the Debentures have been sold pursuant to the Shelf Registration Statement or
Rule 144 under the Act, provided that the Company may suspend the use of the
Shelf Registration Statement for a period not to exceed 45 days in any 12 month
period for valid business reasons, including acquisitions and divestitures of
assets, filings with the Commission, pending corporate developments and similar
reasons.

        On January 31, 2004 and on each January 31 and July 31 thereafter, up to
and including the Maturity Date (each a "Principal Payment Date"), the Company
will cause to be redeemed for cash (at 100%) of the principal amount thereof,
together with accrued interest to the payment date), 25% of the aggregate
principal amount of the Debentures outstanding on each such date, except that
the last such payment (due on the Maturity Date) will be equal to the total
aggregate principal amount of the Debentures outstanding on, and interest
accrued as of, the Maturity Date. Each such redemption of Debentures will be
made pro rata with respect to the outstanding Debentures. In addition, the
Debentures are redeemable, at the option of the Company, at any time on or after
January 31, 2000, at an initial Redemption Price equal to 110.0% of the
principal amount thereof, reducing to a Redemption Price equal to 100.5% of the
principal amount thereof at any time after July 31, 2004, in each case, plus
accrued and unpaid interest to the Redemption Date. The Debentures may also be
redeemed, in whole but not in part, at the option of the Company, at a cash
Redemption Price equal to 100% of their principal amount plus accrued and unpaid
interest top the date of redemption upon the occurrence of certain changes in
United States federal income tax laws.

        Upon a change in control of the Company, each holder of Debentures has
the right during the 45-day period following notice thereof from the Company to
require the Company to repurchase all or a portion of such holder's Debentures
at a cash purchase price equal to 100% of the principal amount of such
Debentures, plus accrued and unpaid interest to the date of repurchase.

                right to indemnification may be reduced to the extent that such

                the defense, compromise or settlement of the Claim, provided

                Indemnified Party and provided the Indemnifying Party
                acknowledges in writing its obligation to indemnify the
                Indemnified Party in accordance with the terms contained in this
                Section in respect of that Claim.

        (c)     Upon the assumption of control of any Claim by the Indemnifying
                Party as set out in subsection (b), the Indemnifying Party shall
                diligently proceed with the defence, compromise or settlement of

                employment of counsel reasonably satisfactory to the Indemnified
                Party and, in connection therewith, the Indemnified Party shall
                cooperate fully, but at the expense of the Indemnifying Party
                with respect to any out-of-pocket expenses incurred, to make

                and witnesses under the Indemnified Party's control, make such
                assignments and take such other steps as in the opinion of
                counsel for the Indemnifying Party are reasonably necessary to
                enable the Indemnifying Party to conduct such defence.

        (d)     The Indemnified Party shall also have the right to participate
                in the negotiation, settlement or defence of any claim or demand
                at its own expense.

        (e)     The final determination of any Claim pursuant to this Section,
                including all related costs and expenses, will be binding and
                conclusive upon the Parties as to the validity or invalidity, as
                the case may be, of such Claim against the Indemnifying Party.

                provided in subsection (b), the Indemnified Party shall be
                entitled to make such settlement of the Claim as in its sole

        THIS AGREEMENT AMENDING THE SHARE PURCHASE AGREEMENT is
made the 24th day of July, 1998

BETWEEN:

               MAGNA INTERNATIONAL INC., a corporation governed by
               the laws of  Ontario, (the "Vendor"),


                                     - and -

               TIERCON HOLDINGS INC., a corporation governed by the laws of
               Ontario, (the "Purchaser").

RECITALS:

A. TRIAM Automotive Inc. ("TAI"), as vendor, and the Purchaser entered into a
share purchase agreement dated July 2, 1998 (the "Share Purchase Agreement")
with respect the sale by TAI to the Purchaser of all of the issued and
outstanding shares (the "Purchased Shares") in the capital of TRIAM Automotive
Canada Inc., a corporation governed by the laws of Ontario (the "Company").

B. TAI has transferred the Purchased Shares to the Vendor, and TAI has assigned
all of its rights and obligations under the Share Purchase Agreement to the
Vendor.

C. The Vendor and the Purchaser wish to record by this amending agreement
certain amendments to the Share Purchase Agreement and certain agreements which
have been entered into with respect to the terms of the closing of the purchase
and sale contemplated by the Share Purchase Agreement.

        NOW THEREFORE, in consideration of the closing of the purchase and sale
contemplated by the Share Purchase Agreement and for other valuable
consideration, the parties agree as follows:

1.      SHARE PURCHASE AGREEMENT DEFINITIONS

Unless defined in this Amending Agreement, all words in this Amending Agreement
beginning with an initial capital shall have the meaning ascribed to them in the
Share Purchase Agreement.


2.      AFFECT OF REDUCTION IN SHAREHOLDERS EQUITY


<PAGE>   2

        a.     The definition of "Shareholders Advances Purchase Price"
               contained in Section 1.1 shall be amended by removing the words "
               less the reduction in Shareholders Equity from $1,700,000, being
               the amount of Shareholders Equity as at 30 April 1998 as
               reflected on the Pro Forma Balance Sheet, to the amount of
               Shareholders Equity on the Effective Date".

        b.     Section 3.1 shall be amended to read:

               'The amount payable by the Purchaser for the Purchased Shares
               (the "Purchase Price"), exclusive of all applicable sales and
               transfer taxes, shall be the amount of $27,000,000 less the sum
               of $1,721,279 being a reasonable pre-estimate of the anticipated
               losses that will be suffered by the Business as a result of the
               current strikes affecting certain operations of General Motors.'

        c.     Section 3.7 (e) shall be amended by adding the words "or the
               Purchase Price, as the case may be," after the words
               "Shareholders Advances Price" in the second last line of Section
               3.7(e).

3.      AUDITED EFFECTIVE DATE BALANCE SHEET

If as a result of the audit of the Effective Date Balance Sheet the operating
loss of the Company from April 30, 1998 to the Effective Date is greater or less
than $553,119, then the Purchase Price for the Purchased Shares will be adjusted
by the amount of such difference (or the difference which may be determined
under Section 3.7 of the Share Purchase Agreement), and the Vendor or the
Purchaser, as the case may be, shall pay to the other by wire transfer of
immediately available funds, certified cheque or bank draft the amount by which
the Purchase Price is to be adjusted.

For greater certainty, the only objection which the Purchaser can make under
Section 3.7 to the Effective Date Balance Sheet is with respect to the amount of
the operating loss of the Company between April 30, 1998 and the Effective Date.

4.      DEFERRED TAXES

The Purchaser shall have no claim against the Vendor under any provision of the
Share Purchase Agreement by reason of the fact that the deferred taxes of the
Company as at the


<PAGE>   3

Effective Date or the Closing Date are greater than the amount reflected on the
Pro Forma Balance Sheet.


               IN WITNESS WHEREOF the Parties have duly executed this Agreement.

                                        MAGNA INTERNATIONAL INC.

Seller of the transactions contemplated hereby, have been duly and validly

delivered prior to Closing.

or regulation applicable to Tiercon or Seller, as the case may be, any material
agreement or instrument to which any of them is a party or by which any of them
or any of their properties are bound, or any order, judgment or decree of any
court or any governmental agency or body having jurisdiction over any of them or
their properties or in a breach or a default under any of their Charter
Documents. No consent, approval, order or authorization of, declaration or
filing with, any governmental authority or entity or other party is required to
be obtained or made by Tiercon in connection with the execution and delivery of

will not be void, voidable, discharged or otherwise affected by the change in

permitted, nor will agree to or permit, any amendment thereto or waiver of any
requirement thereof or default thereunder.

may incur, suffer or become liable for, directly or indirectly, as a result of
or in connection with:

                  (a) Any and all monetary damages or deficiency resulting from
         any misrepresentation, breach of warranty, and/or nonfulfillment of any
         agreement or covenant on the part of Tiercon or Seller, under this
         Agreement or resulting from any misrepresentation or omission from any

<PAGE>   16

                  (b) Any and all actions, suits, proceedings, demands,
         assessments, judgments, costs, and expenses including reasonable
         attorneys fees, incident to any of the foregoing;

provided, however, that within sixty (60) days after learning of the assertion
of any claim against which Noble and/or Acquisition claim indemnification
hereunder, Noble and/or Acquisition, as the case may be, shall notify Seller and
afford it the opportunity to assume the defense or monetary settlement thereof
at Seller's own expense with counsel of Seller's choosing, and Noble and/or
Acquisition, as the case may be, shall have cooperated fully to make available
to Seller all pertinent information under their control or in their possession.
Noble and Acquisition shall have the right to join in the defense of any such
claim with counsel of their own choosing and at their own expense.

         7.2 Indemnification of Seller. Acquisition hereby agrees to indemnify
and hold Seller, its successors and permitted assigns harmless from and against
any and all liability, loss, cost or expense which Seller may suffer or become
liable for as a result or in connection with:

                  (a) Any and all liabilities, obligations and claims, which
         arise from the operation of the business of Tiercon after the Closing
         Date, other than to the extent resulting from any malfeasance,
         misfeasance, negligence, or actions of Seller or any matter referred to
         in Section 7.1; and

                  (b) Any and all monetary damages or deficiency resulting from
         any misrepresentation, breach of warranty, and/or nonfulfillment of any
         agreement or covenant on the part of Noble and/or Acquisition under
         this Agreement or resulting from any misrepresentation or omission from
         any certificate, schedule, list, or other instrument to be furnished by
         Noble and/or Acquisition to Seller under this Agreement;

provided, however, that within sixty (60) days after learning of the assertion
of any claim against which a Seller claims indemnification hereunder, such
Seller shall notify Acquisition and afford it the opportunity to assume the
defense or monetary settlement thereof at its own expense with counsel of its
choosing, and such Seller shall have cooperated fully to make available to
Acquisition all pertinent information under its control or in its possession.
Seller shall have the right to join in the defense of any such claim with
counsel of its own choosing and at Seller's own expense.

         7.3 Failure to Provide Timely Notice. Notwithstanding the notice
requirements provided in Sections 7.1 and 7.2, the right to indemnification
under this Agreement shall not be affected by any failure to give or any delay
in giving such notice unless, and then only to the extent that, the rights and
remedies of the party to whom such notice was to have been given shall have been
prejudiced.

         7.4 Minimization of Indemnities. The parties hereto shall each use
reasonable efforts to minimize the obligation of the other to indemnify under
this Agreement, by, among other 



                  Stock Purchase Agreement (Tiercon), Page 16
<PAGE>   17

reasonable things and without limiting the generality of the foregoing, taking
such reasonable remedial action as it believes may minimize such obligation and
seeking to the maximum extent possible reimbursement from insurance carriers
under applicable insurance policies covering any such liability.

         7.5 Assignment of Claims. The parties agree that upon satisfaction of
the obligation to indemnify hereunder, and in consideration thereof, to assign
to the party making such payment or giving such credit, any and all claims,
causes of action and demands of whatever kind and nature which such indemnified
party may have against any person, firm or other entity giving rise to such
indemnified loss, and to reasonably cooperate in any efforts to recover
therefrom.

         7.6 Acquisition's Right to Settle Claims. After Closing,
notwithstanding anything herein contained to the contrary, in the event that, in
order to protect Tiercon and its business and assets after acquisition of the
Tiercon Shares by Acquisition hereunder, Acquisition shall desire to cause
Tiercon to settle any claims or actions, the defense of which Seller would
otherwise be entitled to assume pursuant to the provisions hereof, Acquisition
shall be entitled to cause Tiercon to so settle such claim or action, after
first giving Seller not less than five (5) days prior written notice of such
claim or action and the proposed settlement, and the terms of such settlement
shall be binding upon Seller so long as they are commercially reasonable.

notifying the Holders of the right to exercise the Exchange Right in respect of
the Exchangeable Shares held by a Holder.

         2.3 PURCHASE PRICE. The purchase price payable by Parent for each
Exchangeable Share to be purchased by Parent under the Exchange Right shall be
an amount per share equal to the Current Market Price, determined on the date
the Exchange Right is exercised pursuant to section 2.4 (the "Exchange Date"),
which shall be satisfied in full by the Corporation causing to be delivered to
each Holder one Parent Share, or, at a Holder's election, US $11.50 in cash
("Cash Compensation"); provided that, in the event that a Holder elects to
receive Cash Compensation in lieu of all or part of the Parent Shares to which
such Holder is entitled pursuant to this section, Corporation may elect, at its
sole discretion, to cause to be delivered to such Holder for each Exchangeable
Share one Parent Share instead of the Cash Compensation elected by such Holder.

         2.4 EXERCISE OF THE EXCHANGE RIGHT. Subject to the terms and conditions
herein set forth, a Holder shall be entitled, upon the occurrence and during the
continuance of a Default Event, to exercise the Exchange Right with respect to
all or any part of the Exchangeable Shares registered in the name of such Holder
on the books of the Corporation. To exercise the Exchange Right, the Holder
shall deliver to Parent, in person, by courier or by certified or registered
mail, at its principal office or at such other place as Parent may from time to
time designate by written notice to the Holders, the certificates representing
the Exchangeable Shares that such Holder desires Parent to purchase pursuant to
the Exchange Right, duly endorsed in blank, and accompanied by such other
documents and instruments as Parent may reasonably require together with:

                  (a) a duly completed form of notice of exercise of the
         Exchange Right, contained on the reverse of or attached to the
         Exchangeable Share certificates, stating (i) that the Holder thereby
         exercises the Exchange Right so as to require Parent to purchase from
         the Holder the number of Exchangeable Shares specified therein, (ii)
         that such Holder has good title to and owns all such Exchangeable
         Shares to be acquired by Parent free and clear of all Liens, (iii) the
         names in which the certificates representing Parent Shares issuable in
         connection with the exercise of the Exchange Right are to be issued,
         and (iv) the names and addresses of the Persons to whom such new
         certificates should be delivered;



                   Share Exchange Agreement (Tiercon), Page 4
<PAGE>   5

                  (b) payment (or evidence satisfactory to Parent of payment) of
         the taxes (if any) payable as contemplated by section 2.7 hereof; and

                  (c) a certificate or certificates of such Holder satisfactory
         to Parent attesting to such Holder's accredited investor status and
         investment intent.

         If only a part of the Exchangeable Shares represented by any
certificate or certificates delivered to Parent are to be purchased by Parent
under the Exchange Right, a new certificate for the balance of such Exchangeable
Shares shall be issued to the Holder at the expense of the Corporation.

         2.5 DELIVERY OF PARENT SHARES: EFFECT OF EXERCISE. Promptly after
receipt of the certificates, duly endorsed in blank, representing the
Exchangeable Shares in respect of which the Exchange Right was exercised
pursuant to section 2.4 hereof (together with such documents and instruments of
transfer and a duly completed form of notice of exercise of the Exchange Right
(and payment of taxes, if any, or evidence thereof in accordance with section
2.4 hereof)), Parent shall notify the Corporation of its receipt of the same
and, subject to section 1.5, Parent shall promptly thereafter deliver or cause
to be delivered to the Holder of such Exchangeable Shares (or to such other
Persons, if any, properly designated by such Holder) (i) the certificates for
the number of Parent Shares issuable in connection with the exercise of the
Exchange Right, which shares shall be duly issued as fully paid and
non-assessable and shall be free and clear of any Liens placed thereon by Parent
or the Corporation, if applicable, or (ii) the corresponding Cash Compensation,
as provided in this Agreement. Immediately upon the exercise of the Exchange
Right, as provided in section 2.4 hereof, the closing of the transaction of
purchase and sale contemplated by the Exchange Right shall be deemed to have
occurred, and the Holder of such Exchangeable Shares shall be deemed to have
transferred to Parent all of its right, title and interest in and to such
Exchangeable Shares free and clear of all Liens and shall cease to be a holder
of such Exchangeable Shares and shall not be entitled to exercise any of the
rights of a holder in respect thereof, other than the right to receive the
purchase price therefor, unless the requisite number of Parent Shares or Cash
Compensation, as the case may be, is not allotted, issued and/or delivered by
Parent to such Holder (or to such other Persons, if any, properly designated by
such Holder) within five Business Days of the Exchange Date, in which case the
rights of the Holder shall remain unaffected until such Parent Shares or Cash
Compensation are so allotted, issued and/or delivered by Parent and any such
cheque or property is so delivered and paid. Concurrently with such Holder
ceasing to be a holder of Exchangeable Shares, the Holder shall be considered
and deemed for all purposes to be a holder of Parent Shares delivered to such
Holder, if any, pursuant to the Exchange Right. The Board of Directors shall
sanction or approve any transfer of Exchangeable Shares made pursuant to an
exercise of the Exchange Right pursuant to the provisions hereof and such
sanction or approval shall be effective as at the closing of the transaction of
purchase and sale of Exchangeable Shares as provided in this section 2.5.

         2.6 STAMP OR OTHER TRANSFER TAXES. Upon any sale of Exchangeable Shares
to Parent pursuant to the Exchange Right, the share certificate or certificates
representing Parent Shares to be delivered in connection with the payment of the
purchase price therefor shall be issued in the name of the Holder of the
Exchangeable Shares so sold or in such names as such Holder may otherwise 


                   Share Exchange Agreement (Tiercon), Page 5
<PAGE>   6

direct in writing without charge to the Holder, provided, however, that such
Holder (a) shall pay (and neither Parent nor the Corporation shall be required
to pay) any documentary, stamp, transfer or other similar taxes that may be
payable in respect of any transfer involved in the issuance or delivery of such
shares to a Person other than such Holder or (b) shall establish to the
satisfaction of Parent and the Corporation that such taxes, if any, have been
paid.

         2.7 NOTICE OF DEFAULT EVENT. Immediately upon the occurrence of a
Default Event, the Corporation and Parent shall give written notice thereof to
the Holders. Such notice shall describe the event that has occurred and shall
specify that, pursuant to this Agreement, the Holders are currently entitled, or
may become entitled at a later date, to exercise the Exchange Right.

         2.8 QUALIFICATION OF PARENT SHARES. Parent shall use all reasonable
efforts to obtain all orders required from the applicable Canadian securities
authorities to permit the issuance of the Parent Shares upon any exchange of the
Exchangeable Shares for Parent Shares without registration or qualification
with, or approval of, or the filing of any document including any prospectus or
similar document, or the taking of any proceeding with, or the obtaining of any
order, ruling or consent from, any governmental or regulatory authority under
any Canadian federal or provincial law or regulation or pursuant to the rules
and regulations of any regulatory authority in Canada or the fulfilment of any
other legal requirement before such Parent Shares may be issued and delivered by
the Corporation or Parent to the holder thereof.

                     AMENDMENTS AND SUPPLEMENTAL AGREEMENTS

         3.1 AMENDMENTS, MODIFICATIONS, ETC. Except as provided for in section
3.2 hereof, this Agreement may not be amended or modified except by an agreement
in writing executed by the Corporation, Holdings, Parent and the Holder. Any
amendment or modification of this Agreement by the Corporation, Holdings, Parent
and the Holder shall bind the Holder, and the Corporation, Holdings, Parent and
the Holder shall be entitled to rely on such amendment or modification for all
purposes.

         3.2 CHANGES IN THE CAPITAL OF PARENT OR THE CORPORATION.
Notwithstanding section 3.1 hereof, at all times after the occurrence of any
Capital Reorganization (as such term is defined in the Exchangeable Share
Provisions), this Agreement shall forthwith be deemed to have been amended and
modified as necessary in order that it shall apply with full force and effect to
all new securities into which Parent Shares or the Exchangeable Shares or both
are so changed and the parties hereto shall execute and deliver an agreement
giving effect to and evidencing such necessary amendments and modifications.

                                    ARTICLE 4

entitled to transfer any Exchangeable Shares except as explicitly 


                   Share Exchange Agreement (Tiercon), Page 6
<PAGE>   7

permitted pursuant to the articles of incorporation of the Corporation. Parent
and the Board of Directors shall not sanction any transfer of Exchangeable
Shares (other than to Parent or any of its Affiliates pursuant to the provisions
hereof or the Exchangeable Share Provisions) unless, as a condition precedent to
any such transfer of Exchangeable Shares, the transferee, if it is not a party
to this Agreement, executes and delivers an agreement in form and containing
terms satisfactory to Parent and the Corporation, acting reasonably, whereby the
transferee shall become a party hereto and shall agree to be bound by the
provisions hereof as if the transferee was an original party hereto, and
thereupon the transferee shall have the same rights, and shall be subject to the
same obligations, as the transferor hereunder.

         ceasing to be a registered holder of Exchangeable Shares, be deemed to

the provision or provisions so held to be invalid, in the reasonable judgment of

         2.1      Demand Registration.

                  (a) Subject to paragraphs (c), (d) and (e) of this Section
         2.1, at any time and from time to time following the first anniversary
         of the execution and delivery of the Exchange Agreement, the
         Securityholder may make a written request for registration under the
         Securities Act of all or part of the Registrable Securities (a "Demand
         Registration"); provided, however, that:

                           (i) the Company will not be obligated to effect a
                  Demand Registration unless the aggregate value of the shares
                  proposed to be offered pursuant to a single registration by
                  the Securityholder equals or exceeds $500,000;

                           (ii) the Company will not be obligated to effect and
                  bear the cost of effecting a Demand Registration on more than
                  a total of one occasion; provided that if the Securityholder
                  or any other holders of Registrable Securities making a Demand
                  Registration agree to bear all administrative, filing and
                  professional costs of effecting such Demand Registration, then
                  the Company will be obligated to effect such Demand
                  Registration, but only on a total of one occasion; and

                           (iii) notwithstanding anything to the contrary in
                  clause (ii) above, the Company will not be obligated to effect
                  more than a total of two Demand Registrations.

Such request will specify the number of shares of Registrable Securities
proposed to be offered 


<PAGE>   5

for sale by the Securityholder and will also specify the intended method of
disposition thereof.

                  (b) If, in connection with any Demand Registration, the
         Company, the Securityholder or any other holders of Registrable
         Securities exercising registration rights also desire to sell shares of
         Common Stock and the managing Underwriter of such offering advises the
         Company, and the Securityholder in writing that the total number of
         shares requested to be so included in such registration exceeds the
         number of shares of Common Stock which can be sold in such offering or
         that the success or pricing of the offering would be materially and
         adversely affected by the inclusion of all of the shares of Common
         Stock requested to be so included, then the Company will include in
         such registration (i) first, the Registrable Securities requested to be
         included by the Securityholder and such other holders exercising
         registration rights, allocated pro rata among them in accordance with
         the number of Registrable Securities held by each of them so that the
         total number of Registrable Securities to be included in such offering
         for the account of all such Persons will not exceed the number
         recommended by such managing Underwriter, (ii) second, the shares of
         Common Stock the Company proposes to offer for sale, which number of
         shares to be registered will be reduced to the extent necessary to
         reduce the total number of shares to be included in such offering to
         the number recommended by such managing Underwriter and (iii) third,
         such number of other shares of Common Stock as the holders thereof
         desire to offer for sale and the Company and the managing Underwriter
         recommend be included in such offering.

                  (c) Notwithstanding the foregoing provisions of this Section
         2.1, the Securityholder may not request a Demand Registration (i) if a
         registration statement has been filed by the Company with the
         Commission, unless such registration statement has been withdrawn or
         has been effective for a period of at least 90 Calendar days, or (ii)
         if an underwritten offering of Common Stock (whether for the account of
         the Company or any other security holders) has been consummated within
         the preceding nine months; provided, however, the limitations in
         clauses (i) and (ii) of this sentence will not apply if the
         Securityholder was not given the opportunity, in accordance with
         Section 2.2, to include its Registrable Securities in the registration
         statement described in clause (i) or the underwritten offering
         described in clause (ii) (as applicable).

                  (d) Notwithstanding the foregoing provisions of this Section
         2.1, the Securityholder will not have the right to initiate or demand a
         registration hereunder unless it proposes to include therein
         Registrable Securities which it believes in good faith to have a value
         of at least $500,000.

                  (e) Notwithstanding the foregoing provisions of this Section
         2.1, in the event the Company receives notice of a Demand Registration,
         the Company may elect once, but only once, by written notice to the
         Securityholder within 20 days after receipt of such notice, to proceed
         with a registration of Common Stock for the Company's account in lieu
         of proceeding with the Demand Registration, in which case the
         provisions of Section 2.2 (and not this Section 2.1) will apply. If the
         Company exercises the right described in the preceding sentence, the
         Security Holders will not be deemed (for purposes of determining 



<PAGE>   6

         the number of future Demand Registrations that may be demanded under
         the terms of this Agreement) to have exercised the right to request a
         Demand Registration unless at least 80% of the Registrable Securities
         that the Securityholder desired to include in such registration were
         included pursuant to Section 2.2.

                  (f) The Securityholder shall be permitted to remove all or any
         part of the Registrable Securities held by the Securityholder from any
         Demand Registration at any time prior to the effective date of the
         registration statement covering such Registrable Securities; provided,
         however, if, as a result of the removal of such Registrable Securities,
         such registration statement is withdrawn by the Company, such Demand
         Registration shall nonetheless count as a Demand Registration for
         purposes of determining the number or future Demand Registration, which
         can be requested pursuant to Section 2.1(a) hereof, unless the
         Securityholder reimburses the Company for all Registration Expenses
         incurred by the Company in connection with such withdrawn Demand
         Registration.

         2.2      Piggyback Rights.

                  (a) If the Company proposes to file a registration statement
         under the Securities Act with respect to an offering of any shares of
         Common Stock (i) for its own account (other than a registration
         statement on Form S-4 or S-8 (or any substitute form that may be
         adopted by the Commission)) or (ii) for the account of any holder of
         its securities having registration rights under the terms of this
         Agreement or any other agreement with the Company, including without
         limitation a Demand Registration, then the Company will give written
         notice of such proposed offering to the Securityholder as soon as
         practicable (provided that the Securityholder will be given such notice
         not less than 20 calendar days prior to the deadline set by the Company
         for electing to include Registrable Securities in such offering), and
         such notice will offer such holders the opportunity, in accordance with
         Section 2.2(b), to register such number of shares of Registrable
         Securities as the Securityholder may request on the same terms and
         conditions as the registration of the Company's or such other holders'
         shares of Common Stock. If the Company so elects, the offering
         contemplated by this Section 2.2 will be in the form of an underwritten
         offering. The Company will select the managing Underwriter and any
         additional Underwriter in connection with the offering.

                  (b) Whenever the Company proposes to file a registration
         statement in accordance with Section 2.2(a), the Company will include
         in such registration all Registrable Securities which the
         Securityholder requests to be included therein; provided, however, that
         if the managing Underwriter of an underwritten offering under this
         Section 2.2 advises the Company and the Securityholder in writing that
         the total number of shares requested to be included in such
         registration exceeds the number of shares of Common Stock which can be
         sold in such offering or that the success or pricing of the offering
         would be materially and adversely affected by the inclusion of all of
         the shares of Common Stock requested to be included, then (except in
         the case of a Demand Registration, as to which Section 2.l(b) will
         govern), the Company will include in such 


<PAGE>   7

         registration (i) first, the shares of Common Stock the Company proposes
         to offer for sale for its own account, (ii) second, the Registrable
         Securities requested to be included by the Securityholder and any other
         holders of Registrable Securities exercising registration rights,
         allocated pro rata among them in accordance with the number of
         Registrable Securities held by each of them so that the total number of
         Registrable Securities to be included in such offering for the account
         of all such Persons will not exceed the number recommended by such
         managing Underwriter, and (iii) third; such number of other shares of
         Common Stock as the holders thereof desire to offer for sale and the
         Company and the managing Underwriter recommend be included in such
         offering.

                  (c) A request by the Securityholder to include Registrable
         Securities in a proposed underwritten offering pursuant to this Section
         2.2 will not be deemed to be a request for a Demand Registration
         pursuant to Section 2.1.

         2.3 Sale of Warrants to Underwriters. Notwithstanding anything in this
Agreement to the contrary (but subject to the last sentence of this Section
2.3), in the case of any offering subject to the provisions hereof which is an
underwritten offering, in lieu of exercising any warrant prior to or
simultaneously with the filing or the effectiveness of any registration
statement filed in connection therewith, the holder of such warrant may,
provided that the Company shall have been advised by the managing Underwriter
that such sale would not adversely affect the overall offering or pricing
thereof, sell such warrant or portion thereof to the underwriter or underwriters
of the offering being registered upon the undertaking of such underwriter or
underwriters to exercise such warrant or portion thereof before making any
distribution pursuant to such registration statement and to include the Common
Stock issued upon such exercise among the Registrable Securities being offered
pursuant to such registration statement. Subject to the next succeeding
sentence, the Company agrees to cause such Common Stock to be included among
tile Registrable Securities being offered pursuant to such registration
statement to be issued within such time as will permit such underwriter or
underwriters to make and complete the distribution contemplated by the
underwriting. In no event. however, shall the Company be required pursuant to
the provisions of this Section 2.3 to include in such registration statement
more shares of Common Stock than the holder of such warrant would otherwise be
entitled to include in such registration statement pursuant to the terms of this
Agreement.


                          III. REGISTRATION PROCEDURES

         3.1 Filings: information. Whenever the Securityholder (the "Registering
Securityholder") requests that any Registrable Securities be registered pursuant
to Article II, the Company will use its best efforts to effect the registration
of such Registrable Securities to the extent required by Article II, as promptly
as is practicable, and in connection with any such request:

                  (a) The Company will as expeditiously as possible prepare and
         file with the Commission a registration statement on any form for which
         the Company then qualifies and which counsel for the Company deems
         appropriate and available for the sale of the 


<PAGE>   8

         Registrable Securities to be registered thereunder in accordance with
         the intended method of distribution thereof, and use its best efforts
         to cause such filed registration statement to become and remain
         effective for a period of not less than 90 calendar days or, if less,
         the period required for such Registrable Securities to be sold;
         provided, however, that if the Company furnishes to the Registering
         Securityholder a certificate signed by the Company's Chief Executive
         Officer stating that the Board of Directors has determined that it
         would be materially detrimental or otherwise materially disadvantageous
         to the Company or its stockholders (whether because of any proposed
         material transaction or otherwise) for such a registration statement to
         be filed as expeditiously as possible, the Company will have a period
         of not more than 120 calendar days within which to file such
         registration statement measured from the date of the Company's receipt
         of the Registering Securityholder's request for registration;

                  (b) The Company will, if requested, prior to filing such
         registration statement or any amendment or supplement thereto, furnish
         to the Registering Securityholder and each applicable Underwriter, if
         any, copies thereof, and thereafter furnish to the Registering
         Securityholder and each such Underwriter, if any, such number of copies
         of such registration statement, amendment and supplement thereto (in
         each case including all exhibits thereto and documents incorporated by
         reference therein) and the prospectus included in such registration
         statement (including each preliminary prospectus) as the Registering
         Securityholder of each such Underwriter may reasonably request in order
         to facilitate the sale of the Registrable Securities;

                  (c) After the filing of the registration statement, the
         Company will promptly notify the Registering Securityholder of any stop
         order issued or, to the Company's knowledge, threatened to be issued by
         the Commission or any state, securities agency or authority and take
         all reasonable actions required to prevent the entry of such stop order
         or to remove it if entered;

                  (d) The Company will endeavor to qualify the Registrable
         Securities for offer and sale under such other securities or blue sky
         laws of such jurisdictions in the United States as the Registering
         Securityholder reasonably requests; provided, however, that the Company
         will not be required to (i).qualify generally to do business in any
         jurisdiction where it would not otherwise be required to qualify but
         for this subsection (d), (ii) subject itself to taxation in any such
         jurisdiction, or (iii) consent to general service of process in any
         such jurisdiction;

                  (e) The Company will as promptly as is practicable notify the
         Registering Securityholder, at any time when a prospectus relating to
         the sale of the Registrable Securities is required by law to be
         delivered in connection with sales by an Underwriter or dealer, of the
         occurrence of any event requiring the preparation of a supplement or
         amendment to such prospectus so that, as thereafter delivered to the
         purchasers of such Registrable Securities, such prospectus will not
         contain an untrue statement of a material fact or omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not 

<PAGE>   9

         misleading and promptly make available to the Registering
         Securityholder and to the Underwriters any such supplement or
         amendment. The Registering Securityholder agrees that, upon receipt of
         any notice from the Company of the occurrence of any event of the kind
         described in the preceding sentence, the Registering Securityholder
         will forthwith discontinue the offer and sale of Registrable Securities
         pursuant to the registration statement covering such Registrable
         Securities until receipt by the Registering Securityholder and the
         Underwriters of the copies of such supplemented or amended prospectus
         and, if so directed by the Company, the Registering Securityholder will
         deliver to the Company all copies, other than permanent file copies
         then in the Registering Securityholder possession, of the most recent
         prospectus covering such Registrable Securities at the time of receipt
         of such notice. In the event the Company gives such notice, the Company
         will extend the period during which such registration statement will be
         effective as provided in Section 3.1(a) by the number of days during
         the period from and including the date of the giving of such notice to
         the date when the Company will make available to the Registering
         Securityholder such supplemented or amended prospectus;

                  (f) The Company will enter into customary agreements
         (including in the case of an underwritten offering an underwriting
         agreement in customary form) and the Company and its officers will take
         such other actions as are reasonably required in order to expedite or
         facilitate the sale of such Registrable Securities, including
         participation in any "road show" undertaken in connection with such
         sale;

                  (g) The Company will furnish to the Registering Securityholder
         and to each Underwriter a signed counterpart, addressed to the
         Registering Securityholder or such Underwriter, of (i) an opinion or
         opinions of counsel to the Company and (ii) a comfort letter or comfort
         letters from the Company's independent public accountants, each in
         customary form and covering such matters of the type customarily
         covered by opinions or comfort letters, as the case may be, as the
         Registering Securityholder or the managing Underwriter may reasonably
         request;

                  (h) The Company will make generally available to its security
         holders, as soon as reasonably practicable, an earnings statement
         covering a period of 12 months, beginning within three months after the
         effective date of the registration statement, which earnings statement
         will satisfy the provisions of Section 11(a) of the 1933 Act and the
         rules and regulations either Commission thereunder;

                  (i) The Company will use its reasonable efforts to cause all
         such Registrable Securities to be listed on each securities exchange on
         which securities of the same class issued by the Company are then
         listed;

                  (j) The Company may require the Registering Securityholder
         promptly to furnish in writing to the Company such information
         regarding the Registering Securityholder, the plan of distribution of
         the Registrable Securities and other information as the Company may
         from time to time reasonably request or as may be legally required in
         connection with such registration. The furnishing of such information


<PAGE>   10

         will be a condition to the Company's obligations hereunder;

                  (k) The Company will notify the Registering Securityholder,
         its counsel and the managing underwriters, if any, as soon as possible
         and (if requested by any such Person) confirm such notice in writing,
         (i) when a prospectus relating to the Registrable Securities or any
         prospectus supplement or post-effective amendment has been filed and,
         with respect to a registration statement relating to the Registrable
         Securities or any post-effective amendment, when the same has become
         effective, (ii) of any request by the Commission for amendments or
         supplements to a registration statement relating to the Registrable
         Securities or related prospectus or for additional information, (iii)
         of the issuance by the Commission of any stop order suspending the
         effectiveness of a Registration Statement relating to the Registrable
         Securities or the initiation of any proceedings for that purpose, (iv)
         of the receipt by the Company of any notification with respect to the
         suspension of the qualification of any of the Registrable Securities
         for sale in any jurisdiction or the initiation or threatening of any
         proceeding for such purpose, and (v) of the Company's reasonable
         determination that a post-effective amendment to a registration
         statement relating to the Registrable Securities would be appropriate
         or that there exist circumstances not yet disclosed to the public which
         make further suits under such registration statement inadvisable
         pending such disclosure and post-effective amendment;

                  (l) Upon the occurrence of any event contemplated by paragraph
         (a) above, promptly prepare a supplement or post-effective amendment to
         the registration statement relating to the Registrable Securities or
         related prospectus or any document incorporated therein by reference or
         file any other required document so that (i) such registration
         statement will not contain any untrue statement of a material fact or
         omit to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading or (ii) as
         thereafter delivered to the purchasers of the registrable securities
         being sold thereunder, such prospectus will not include an untrue
         statement of a material fact or omit to state a material fact necessary
         in order to make the statements therein in light of the circumstances
         under which they were made, not misleading:

                  (m) Make every reasonable effort to obtain the withdrawal of
         any order suspending the effectiveness of a registration statement
         relating to the Registrable Securities, at the lifting at any
         suspension of the qualification of any of the Registrable Securities
         for sale in any jurisdiction, at the earliest possible moment;

                  (n) (i) If reasonably requested by the managing underwriter or
         any Registering Securityholder, promptly incorporate in a prospectus
         supplement or post-effective amendment such information concerning such
         Registering Securityholder, the managing underwriter or underwriters or
         the intended method of distribution as the managing underwriter or
         underwriters or the Registering Securityholder reasonably requests to
         be included therein and as is appropriate in the reasonable judgment of
         the Company including, without limitation, information with respect to
         the number of shares of the Registrable Securities being sold to such
         underwriter or underwriters, the purchase price being paid therefor by
         such underwriter or underwriters, the purchase price 

<PAGE>   11

         being paid therefor by such underwriter or underwriters and with
         respect to any other terms of the underwritten (or best efforts
         underwritten) offering of the Registrable Securities to be sold in such
         offering; and (ii) make all required filings of such prospectus
         supplement or post-effective amendment as promptly as practicable after
         being notified of the matters to be incorporated therein;

                  (o) Furnish to each Registering Securityholder and each
         managing underwriter, if any, without charge, one manually signed copy
         of the registration statement relating to the Registrable Securities
         and any post-effective amendments thereto, including financial
         statements and schedules and, upon request, all documents incorporated
         therein by reference and all exhibits (including those incorporated by
         reference);

                  (p) Provide a transfer agent and registrar for the Registrable
         Securities not later than the effective date of the registration
         statement relating to the Registrable Securities.

         3.2 Registration Expenses. Registration Expenses incurred in connection
with any registration made or requested to be made pursuant to Article II will
be borne by the Company, whether or not any such registration statement becomes
effective, to the extent permitted by applicable law. The Registering
Securityholder will pay, on a pro rata basis, any underwriting fees, discounts
or commissions attributable to the sale of the Registrable Securities.

         3.3 Indemnification by the Company. The Company agrees to indemnify and
hold harmless each Registering Securityholder, its officers, directors, members,
managers and agents, and each Person, if any, who controls each such Registering
Securityholder within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act from and against any and all losses, claims, damages,
liabilities and expenses caused by any untrue statement or alleged untrue
statement of a material fact contained in any registration statement or
prospectus relating to the Registrable Securities (as amended or supplemented if
the Company shall have furnished any amendments or supplements thereto) or any
preliminary prospectus, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages, liabilities or expenses are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information
furnished in writing to the Company by or on behalf of such Registering
Securityholder expressly for use therein; provided, however, that the foregoing
indemnity agreement with respect to any preliminary prospectus will not inure to
the benefit of any Registering Securityholder if a copy of the current
prospectus was not provided, in the manner required by applicable regulations,
to the applicable purchaser by such Registering Securityholder and such current
copy of the prospectus would have cured the defect giving rise to such loss,
claim, damage, liability or expenses. The Company also agrees to indemnify any
Underwriters of the Registrable Securities, their officers and directors and
each Person who controls such underwriters on substantially the same basis as
that of the indemnification of the Registering Securityholder provided in this
Section 3.3.


<PAGE>   12

         3.4 Indemnification by Registering Securityholder. Each Registering
Securityholder registering shares pursuant to Article II agrees, severally but
not jointly, to indemnify and hold harmless the Company, its officers and
Directors and each Person, if any, who controls the Company within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the foregoing indemnity from the Company to such Registering
Securityholder, but only with reference to information related to such
Registering Securityholder furnished in writing by or on behalf of such
Registering Securityholder expressly for use in any registration statement of
prospectus relating to the Registrable Securities, or any amendment or
supplement thereto or any preliminary prospectus; provided, however. that in no
event will the liability of any Registering Securityholder under this Section
3.4 be greater in amount than the dollar amount of the proceeds received by such
holder upon the sale of the Registrable Securities giving rise to such
indemnification obligation. Each such Registering Securityholder also agrees to
indemnify and hold harmless any Underwriters of the Registrable Securities,
their officers and directors and each Person who controls such Underwriters on
such terms as provided for in underwriting agreement relating to such offering.

         3.5 Conduct of Indemnification Proceedings. In case any proceeding
(including any governmental investigation) is instituted involving any person in
respect of which indemnity may be sought pursuant to Section 3.3 or Section 3.4,
such Person will promptly notify the Person against whom such indemnity may be
sought in writing and the indemnifying party upon request of the indemnified
party will retain counsel reasonably satisfactory to the indemnified party to
represent the indemnified party and any others the indemnifying party may
designate in such proceeding and will pay the fees and disbursements of such
counsel related to the proceeding; provided, however, that the failure to so
notify the indemnifying Person shall not relieve the indemnifying party from any
liability that it may otherwise have to such indemnified Person, except to the
extent the indemnifying Person shall have been materially prejudiced by such
failure. In any such proceeding, any indemnified party will have the right to
retain its own counsel, but the fees and expenses of such counsel will be at the
expense of such indemnified party unless (a) the indemnifying party and the
indemnified party have mutually agreed to the retention of such counsel or (b)
the named parties to any such proceeding (including any impleaded parties)
include both the indemnified party and the indemnifying party and representation
of both parties by the same counsel would be inappropriate due to actual of
potential differing interests between them, in which case the fees and expenses
of such counsel will be paid by the Company. It is understood that the
indemnifying party will not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) at any time for all such indemnified parties, and that all such
reasonable fees and expenses will be reimbursed as they are incurred. In the
case of the retention of any such separate firm for the indemnified parties,
such firm will be designated in writing by the indemnified parties. The
indemnifying party will not be liable for any settlement or any proceeding
effected without its consent, but if settled with such consent, or if there be a
final judgment for the plaintiff, the indemnifying party will indemnify and hold
harmless such indemnified parties from and against any loss or liability (to the
extent stated above) by reason of such settlement or judgment.


<PAGE>   13

         3.6      Contribution.

                  (a) If the indemnification provided for herein is for any
         reason unavailable to the indemnified parties in respect of any losses,
         claims, damages or liabilities referred to herein, then each such
         indemnifying party, in lieu of indemnifying such indemnified party,
         will contribute to the amount paid or payable by such indemnified party
         as a result of such losses, claims, damages or liabilities in such
         proportion as is appropriate to reflect the relative fault of the
         Company, the Registering Securityholder and any Underwriter in
         connection with the statements or omissions which resulted in such
         losses, claims, damages or liabilities, as well as any other relevant
         equitable considerations. The relative fault of the Company, the
         Registering Securityholder and the Underwriter will be determined by
         reference to, among other things, whether the untrue or alleged untrue
         statement of a material fact or the omission or alleged omission to
         state a material fact relates to information supplied by such party,
         and the parties' relative intent, knowledge, access to information and
         opportunity to correct or prevent such statement or omission.

                  (b) The Company and each Registering Securityholder agree that
         it would not be just and equitable if contribution pursuant to this
         Section 3.6 were determined by pro rata allocation (even if the
         Underwriters were treated as one entity for such purpose) or by any
         other method of allocation which does not take account of the equitable
         considerations referred to in the immediately preceding subsection. The
         amount paid or payable by an indemnified party as a result of the
         losses, claims, damages or liabilities referred to in the immediately
         preceding subsection will be deemed to include, subject to the
         limitations set forth above, any legal or other expenses reasonably
         incurred by such indemnified party in connection with investigating or
         defending any such action or claim. Notwithstanding the provisions of
         this Section 3.6, no Registering Securityholder will be required to
         contribute any amount by reason of such untrue or alleged untrue
         statement or omission or alleged omission in excess of the amount
         received by such Registering Securityholder upon the sale of the
         Registrable Securities giving rise to such contribution obligation. No
         person guilty of fraudulent misrepresentation (within the meaning of
         Section 11(f) of the Securities Act) will be entitled to contribution
         from any person who was not guilty of such fraudulent
         misrepresentation.

         3.7 Participation in Underwritten Registrations. Notwithstanding any
other provision of this Agreement, no Person may participate in any underwritten
registration hereunder unless such Person (a) agrees to sell such Person's
securities on the basis provided in any reasonable underwriting arrangements
approved by the Company or other Persons entitled hereunder to approve such
arrangements and (b) completes and executes all customary questionnaires, powers
of attorney, indemnities, underwriting agreements, "lock-up" agreements and
other documents reasonably required under the terms of such underwriting
arrangements and these registration rights.

         3.8 Rule 144. The Company will file any reports required to be filed by
it under the Securities Act and the Exchange Act and will take such further
action as any Securityholder may reasonably request to the extent required from
time to time to enable the Securityholder to sell 

<PAGE>   14

Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by Rule 144 under the Exchange Act, as
such Rule may be amended from time to time, or other appropriate rule or
regulation adopted by the Commission. Upon the request of any Securityholder,
the Company will deliver to the Securityholder a written statement as to whether
the Company has complied with such reporting requirements.

         3.9 Restrictions on Public Sale by Holders of Registrable Securities.

                  (a) If and to the extent requested by the managing Underwriter
         or Underwriters in the case of an underwritten Public Offering, each of
         the Securityholder agrees not to effect, except as part of such
         registration, any sale of the shares of Common Stock or a similar
         security of the Company, or any securities convertible into or
         exchangeable or exercisable for such securities during such time period
         (not to exceed 180 days) to which the Company agrees not to effect any
         sale of securities in connection therewith, or to which the Registering
         Securityholder agrees if the Company does not include any securities
         therein. In addition, each of the Securityholder agrees to execute any
         customary lock-up agreement reasonably requested by the managing
         Underwriter to confirm its agreement in accordance with the preceding
         sentence, but only if identical lock-up agreements are required of all
         Securityholder.

                  (b) Nothing in this Agreement will diminish or otherwise
         affect the restrictions on transfer contained in the Securityholder
         Agreement.

         3.10 Representation Concerning Future Registration Rights. Nothing in
this Agreement shall be deemed to limit in any way the right of the Company to
grant registration rights on the Company=s securities to any person at any time
prior to or subsequent to the execution of this Agreement.

               (e) Any request, demand, authorization, direction, notice,
consent, election, waiver or other Act of the Holder of any Security shall bind
every future Holder of the same Security appertaining thereto and the Holder of
every Security issued upon the registration of transfer thereof or in exchange

of such notice.

               Neither the failure to give notice nor any defect in any notice
to any Holder shall affect the sufficiency of any notice to any other Holder.
If, due to the suspension of publication of any Authorized Newspaper or
Authorized Newspapers or any other cause it shall be impracticable to publish
any notice as provided above, or if, due to the suspension of regular mail
service or any other cause it shall be impracticable to give notice by mail,
then such notification shall be given in a manner approved by the Trustee, which
approval shall not be unreasonably withheld, shall constitute sufficient notice
to such Holders for every purpose hereunder.

               Notice given pursuant to this Section shall be deemed to have
been given on the date such notice is published or mailed.

               Where this Indenture provides for notice, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders of Securities shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

               SECTION 1.07. EFFECT OF HEADINGS AND TABLE OF CONTENTS. The
Article and Section headings herein and the Table of Contents are for

directly by, the holders of Senior Indebtedness.

Payment Date, Redemption Date, Repurchase Date or Stated Maturity of any
Security or the last day on which a Holder of a Security has a right to convert
his Security shall not be a Business Day at a Place of Payment or Place of
Conversion, as the case may be, then (notwithstanding any other provision of
this Indenture or of the Securities) payment of interest or principal and
premium, if any, or delivery for conversion of such Security need not be made at
such Place of Payment or Place of Conversion, as the case may be, on or by such

Payment or Place of Conversion, as the case may be, with the same force and
effect as if made on the Interest Payment Date, Redemption Date or Purchase

no interest shall accrue on the amount so payable for the period from and after

Board, its Vice Chairman of the Board, its Chief Executive Officer, its
President or one of its Vice Presidents, under a facsimile of its corporate seal
reproduced thereon attested by its Secretary or one of its Assistant
Secretaries. Any such signature may be manual or facsimile.

               Securities bearing the manual or facsimile signature of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

               At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities executed by the
Company to the Trustee or to its order for authentication, together with a
Company Order for the authentication and delivery of such Securities, and the
Trustee or an Authenticating Agent in accordance with such Company Order shall
authenticate and make available for delivery such Securities as in this
Indenture provided and not otherwise. In connection with any Company Order for
authentication, an Officers' Certificate and Opinion of Counsel pursuant to
Section 1.02 shall not be required.

               No Security shall be entitled to any benefit under this Indenture
or be valid or obligatory for any purpose unless there appears on such Security
a certificate of authentication substantially in the form provided for execution
by the Trustee or an Authenticating Agent by manual signature of an authorized




                                       19
<PAGE>   26

signatory, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder. Each Security shall be dated the date of its
authentication.

               SECTION 2.04.  FORM.

               (a) FORMS GENERALLY. The Securities shall be in substantially the
forms set forth in Exhibits A and B hereto, the Trustee's certificates of
authentication shall be in substantially the form set forth in Exhibits A and B,
and the conversion notice shall be in substantially the forms set forth
in Exhibits A and B, each of which is hereby incorporated in and expressly made
part of this Indenture, with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture, and may have such letters, numbers or other marks of identification
and such legends or endorsements placed thereon as may be required to comply
with applicable law, including, without limitation, the United States Internal
Revenue Code of 1986, as amended (the "Code"), and the regulations thereunder,
the rules of any securities exchange, agreements to which the Company is subject
or as may, consistently herewith, be determined by the officers executing such
Securities, as evidenced by their execution thereof. The Global Security may be
printed, lithographed, typewritten, mimeographed or otherwise produced, as
determined by the officers of the Company executing such Security, as evidenced
by their execution thereof. The format and spacing of the text of the Global
Security may be varied to facilitate such production. Definitive Securities
shall be printed, lithographed or engraved or produced by any combination of
these methods on steel engraved borders or may be produced in any other manner
permitted by the rules of any securities exchange on which the Securities may be
listed, all as determined by the officers executing such Securities, as
evidenced by their execution thereof. The format and spacing of the text of a
Definitive Security may be varied to facilitate such production.

               (b) GLOBAL SECURITIES. Except as otherwise provided in this
Section 2.04(b), the Securities and PIK Securities, when issued, shall be issued
in the form of a Global Security, the form of which is set forth in Exhibit A.
Each Global Security shall be deposited on behalf of the subscribers for the
Securities represented thereby with a common depositary (the "Depositary"), for
credit to their respective accounts (or to such other accounts as they may
direct) at Morgan Guaranty Trust Company of New York, Brussels office, or its
successor as operator of the Euroclear Clearance System ("EUROCLEAR"), or Cedel
Bank, societe anonyme ("CEDEL"). The principal amount of the Global Security
evidencing Securities may be increased from time to time after the Initial
Closing Date by means of appropriate adjustments made on the records of the
Trustee or the 





                                       20
<PAGE>   27

Authenticating Agent, whereupon the Trustee or the Authenticating Agent will
instruct the Depositary or its authorized representative to make a corresponding
adjustment to its records, but in no event shall the principal amount as so
increased exceed U.S.$47,762,092 in the aggregate at any time.

               The Securities shall bear the legends set forth on their
respective forms in Exhibits A and B. The Trustee shall not issue any unlegended
Security until it has received an Officers' Certificate from the Company
directing it to do so.

               The Depositary or its nominee shall be the Holder of
the Global Security, and owners of beneficial interests in the Securities
represented by the Global Security shall hold such interests pursuant to the
Applicable Procedures. Any such owner's beneficial ownership of any such
Securities will be shown only on, and the transfer of such ownership interest
shall be effected only through, records maintained by EUROCLEAR or CEDEL.
Transfer of interests in the Global Security shall be subject to the provisions
of Section 2.05(b).

               Unless (A) the Depositary notifies the Company that it is
unwilling or unable to continue as the depositary for the Global Security, and a
successor depository is not appointed within 90 days of such notice, or (B) an
Event of Default has occurred and is continuing with respect to a Global
Security, owners of beneficial interests in a Global Security will not be
entitled to have any portions of such Global Security registered in their names,
will not receive or be entitled to receive physical delivery of Definitive
Securities and will not be considered the owners or holders of the Global
Security. Upon the occurrence of an event described in the preceding sentence,
the Depository shall cause the Global Security to be exchanged for Definitive
Securities as provided in the next paragraph.

               Definitive Securities issued in exchange for a Global Security
pursuant to the preceding paragraph, shall have an aggregate principal amount
equal to that of such Global Security or portion thereof to be so exchanged,
shall be registered in such names and be in such authorized denominations as the
Depositary shall designate and shall bear any legends required hereunder. Any
Global Security to be exchanged in whole shall be surrendered by the Depositary
to the Trustee, as Security Registrar. Upon any surrender of a Global Security,
the Trustee shall authenticate and deliver the Securities issuable on such
exchange to or upon the order of the Depositary or an authorized representative
thereof. In the event of the occurrence of any of the events specified in the
preceding paragraph, the Company will promptly make available to the Trustee a
reasonable supply of Definitive Securities.

               Except as otherwise set forth in this Indenture or a Global
Security, owners of beneficial interests in the Securities





                                       21
<PAGE>   28

evidenced by a Global Security will not be entitled to any rights under the
Indenture with respect to such Global Security, and the Depositary or its
nominee may be treated by the Company, the Trustee and any agent of the Company
or the Trustee as the owner and Holder of such Global Security for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Trustee or any such agent from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or its
nominee or impair, as between the Depositary or its nominee and such owners of
beneficial interests, the operation of the Applicable Procedures.

               SECTION 2.05.  REGISTRATION, REGISTRATION OF TRANSFER
AND EXCHANGE RESTRICTIONS ON TRANSFER.

               (a) The Company shall cause to be kept at the Corporate Trust
Office of the Trustee a register (the register maintained in such office and in
any other office or agency of the Company designated pursuant to Section 8.02
being herein sometimes collectively referred to as the "Security Register") in
which, subject to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Securities and of transfers of Securities.
The Trustee is hereby appointed Security Registrar (the "Security Registrar" or
"Registrar") for the purpose of registering Securities and transfers and
exchanges of Securities as herein provided.

               Upon surrender for registration of transfer of any Security at an
office or agency of the Company designated pursuant to Section 8.02 for such
purpose (a "Transfer Agent"), the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of any authorized denominations and of a
like aggregate principal amount and bearing such restrictive legends as may be
required by this Indenture.

               At the option of the Holder, and subject to the other provisions
of this Section 2.05, Securities may be exchanged for other Securities of any
authorized denominations and of a like aggregate principal amount, upon
surrender of the Global Security to be exchanged at any such office or agency.
Whenever any Securities are so surrendered for exchange, and subject to the
other provisions of this Section 2.05, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive. Every Security presented or surrendered for
registration of transfer or for exchange shall (if so required by the Company or
the Security Registrar) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed, by the Holder thereof or his attorney duly authorized
in writing.




                                       22
<PAGE>   29


               All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company, evidencing
the same debt, and subject to the other provisions of this Section 2.05,
entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

               No service charge shall be made for any registration of transfer
or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 2.04 or 10.02 (other than, in the case of
Securities, where Conversions Shares are to be issued or delivered in a name
other than that of the Holder of the Security) not involving any transfer.

               In the event of a redemption of the Securities in part, the
Company will not be required (a) to register the transfer of, or exchange, any
Security for a period of 15 days immediately preceding the date notice is given
identifying the serial numbers of the Securities called for such redemption or
(b) to register the transfer of, or exchange any Security, or portion thereof,
called for redemption.

               (b) Notwithstanding any other provisions of this Indenture or the
Securities, transfers of a Global Security and transfers and exchanges of
interests therein or of other Securities of the kind described in clauses (1)
and (2) below shall be made only in accordance with this Section 2.05(b).
Transfers and exchanges subject to this Section 2.05 shall also be subject to
the other provisions of this Indenture that are not inconsistent with this
Section 2.05.

                      (1)    A Global Security may not be transferred, in
whole or in part, to any Person other than the Depositary or a nominee thereof,
and no such transfer to any such other Person may be registered; provided, that
this Clause (1) shall not prohibit any transfer of a Security that is issued in
exchange for a Global Security but is not itself a Global Security. No transfer
of a Security to any Person shall be effective under this Indenture or the
Securities unless and until such Security has been registered in the name of
such Person. Nothing in this Section 2.05(b)(1) shall prohibit or render
ineffective any transfer of a beneficial interest in a Global Security effected
in accordance with the Applicable Procedures.

                      (2) In the event that a Global Security is exchanged for
Securities other than Global Securities, such other Securities may in turn be
exchanged (on transfer or otherwise) for Securities that are not Global
Securities or for beneficial interests in a Global Security (if any is then
outstanding) only





                                       23
<PAGE>   30

in accordance with such procedures as may be adopted by the Company and the
Trustee from time to time.

               As used in this Section 2.05, the term "transfer" encompasses any
sale, pledge, transfer or other disposition of a Security.

               (c) None of the Trustee, the Paying Agents, or the Registrar, nor
any of their agents, shall (1) have any duty to monitor compliance with or with
respect to any federal or state or other securities or tax laws or (2) have any
duty to obtain documentation on any transfers or exchanges other than as
specifically required hereunder.

               SECTION 2.06. MUTILATED, DESTROYED, LOST OR STOLEN SECURITIES. If
any mutilated Security is surrendered to the Trustee, the Company shall execute,
the Trustee or an Authenticating Agent shall authenticate and the Trustee shall
deliver in exchange therefor a new Security of like tenor and principal amount
and bearing a number not contemporaneously outstanding.

               If there be delivered to the Company and either to the Trustee:

               (1)  evidence to their satisfaction of the destruction,
loss or theft of any Security, and

               (2) such security, bond or indemnity as may be reasonably
satisfactory to the Company and the Trustee to save each of them and any agent
of either of them harmless,

then, in the absence of actual notice to the Company and the Trustee that such
Security has been acquired by a bona fide purchaser, the Company shall execute,
the Trustee or an Authenticating Agent shall authenticate and the Trustee shall
deliver, in lieu of any such destroyed, lost or stolen Security for a new
Security of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

               Upon the issuance of any new Security under this Section 2.06,
the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee and the Paying Agents
connected therewith).

               Every new Security issued pursuant to this Section 2.06 in lieu
of any mutilated, destroyed, lost or stolen Security shall constitute an
original additional contractual obligation of the Company, whether or not the
mutilated, destroyed, lost or stolen Security shall be at any time enforceable
by anyone, and





                                       24
<PAGE>   31

such new Security, shall be entitled to all the benefits of this Indenture
equally and proportionately with any and all other Securities duly issued
hereunder.

               The provisions of this Section 2.06 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies of any Holder with
respect to the replacement or payment of mutilated, destroyed, lost or stolen
Securities.

               SECTION 2.07. PAYMENT OF INTEREST, INTEREST RIGHTS PRESERVED.
Interest on any Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the immediately preceding Regular Record Date.

               On each Interest Payment Date during the PIK Payment Period, the
Company shall, in lieu of the payment of interest in cash, execute, and require
the Trustee (upon Company Order given not less than 10 days prior to such
Interest Payment Date) to authenticate for original issue, and issue to the
appropriate Holders, PIK Securities in an aggregate principal amount equal to
the amount of cash interest not paid on such Interest Payment Date. The issuance
of such PIK Securities shall constitute full payment of such interest. Each
issuance of PIK Securities in lieu of the payment of interest in cash shall be
made pro rata with respect to the Outstanding Securities; provided, however, in
the event that any such payment of PIK Securities would result in the issuance
of any PIK Security in a principal amount which is less than $1,000 or which is
not an integral multiple of $1,000 (such principal amount, if less than $1,000,
or, if such principal amount is greater than $1,000, the difference between such
principal amount and the highest integral multiple of $1,000 which is less than
such principal amount, being hereinafter referred to as a "Fractional Principal
Amount"), the Company shall cause the Paying Agent to pay the Holders otherwise
entitled to Fractional Principal Amounts of PIK Securities a payment in cash in
lieu thereof equal to, at the Company's option, either (a) each such Holder's
proportionate interest in the net proceeds from the sale or sales in the open
market by the Company, on behalf of all such Holders, of the aggregate of the
Fractional Principal Amounts or (b) the amount of such Holder's Fractional
Principal Amount. If the Company defaults in issuing the requisite PIK
Securities on an Interest Payment Date during the PIK Payment Period, the
Company will thereafter be obligated to pay the aggregate amount of accrued
interest required to be paid on such Interest Payment Date in cash as provided
below. PIK Securities shall be subject to all of the provisions of this
Indenture and, when issued, will be issued in the form of one Global Security
subject to the provisions of Section 2.04(b).




                                       25
<PAGE>   32

               Any interest on any Security which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date ("Defaulted
Interest") shall forthwith cease to be payable to the Holder of such Security on
the relevant Regular Record Date by virtue of having been Holder on such date,
and such Defaulted Interest (and interest on such Defaulted Interest to the
extent lawful) may be paid by the Company in any lawful manner not inconsistent
with the requirements of any securities exchange on which the Securities may be
listed and upon such notice as may be required by such exchange, if, after
notice given by the Company to the Trustee of the proposed payment pursuant to
this paragraph, such manner of payment shall be deemed practicable by the
Trustee. The Company may pay the Defaulted Interest to the persons who are
Holders of the Securities on a subsequent special record date ("Special Record
Date"). The Company shall fix or cause to be fixed any such Special Record Date
and payment date to the reasonable satisfaction of the Trustee and shall
promptly mail to each Holder of a Security a notice that states the special
record date, the payment date and the amount of defaulted interest to be paid.

               Subject to the foregoing provisions of this Section and Section
2.05, each Security delivered under this Indenture upon registration of transfer
of or in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

               In the case of any Security which is converted after any Regular
Record Date and on or prior to the next succeeding Interest Payment Date (other
than any Security whose Stated Maturity is prior to such Interest Payment Date),
interest payable on such Interest Payment Date shall be payable on such Interest
Payment Date notwithstanding such conversion, and such interest (whether or not
punctually paid or duly provided for) shall be paid to the Person in whose name
such Security (or one or more Predecessor Securities) is registered at the close
of business on such Regular Record Date. Except as otherwise expressly provided
in the immediately preceding sentence, in the case of any Security which is
converted, interest payable after the date of conversion of such Security shall
not be payable.

               SECTION 2.08. PERSONS DEEMED OWNERS. Prior to due presentment of
a Security for registration of transfer, and prior to the effective registration
of such transfer in the Security Register the Company, the Trustee and any agent
of the Company or the Trustee may treat the Person in whose name such Security
is registered as the owner of such Security for the purpose of receiving payment
of principal of, premium, if any, and (subject to Sections 2.05 and 2.07)
interest on such Security and for all other purposes whatsoever, whether or not
such Security be overdue, and neither the Company, the Trustee nor any agent of




                                       26
<PAGE>   33

the Company or the Trustee shall be affected by notice to the contrary.

               SECTION 2.09. CANCELLATION. All Securities surrendered for
payment, redemption, repurchase, registration of transfer or exchange or
conversion shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee. All Securities so delivered to the Trustee shall be
canceled promptly by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section 2.09,
except as otherwise permitted by this Indenture. Unless otherwise requested by
the Company and confirmed in writing, the Trustee shall, from time to time but
not less than once annually, destroy all canceled Securities and deliver to the
Company a certificate of destruction, which certificate shall specify the
number, principal amount and, the form of each canceled Security so destroyed.

               SECTION 2.10 COMPUTATION OF INTEREST. Interest on the Securities
shall be computed on the basis of a 360-day year of twelve 30-day months.

               SECTION 2.11. ISIN AND COMMON CODE NUMBERS. The Company in
issuing Securities may use "ISIN" and Common Code numbers (if then generally in
use), and, if so, the Trustee shall use such "ISIN" and Common Code numbers in
addition to serial numbers, in notices of redemption as a convenience to
Holders; provided that any such notice may state that no representation is made
as to the correctness of such ISIN and Common Code numbers either as printed on
the Securities or as contained in any notice of a redemption and that reliance
may be placed only on the serial or other identification numbers printed on the
Securities, and any such redemption or repurchase shall not be affected by any
defect in or omission in the ISIN or Common Code numbers.


                                   ARTICLE III

                               DEFAULTS, REMEDIES

               SECTION 3.01. EVENTS OF DEFAULT. "Event of Default", wherever
used herein, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be occasioned by the provisions of Article
XI or be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body):

               (a) default in the payment of any interest (including any
Additional Amount) upon any Security when it becomes due and





                                       27
<PAGE>   34

payable, and continuance of such default for a period of 30 days; or

               (b) default in the payment of the principal of any Security at
its Maturity; or default in the payment of the Redemption Price or Purchase
Price of any Security when the same becomes due (whether or not such payment is
prohibited by the provisions of this Indenture); or

               (c) the failure to deliver Conversion Shares (together with cash,
if any, in lieu of fractional shares) when such Conversion Shares (and cash, if
any, in lieu of fractional shares) are required to be delivered following the
conversion of a Security (or portion thereof) and continuation of such default
for a period of 10 days; or

               (d) the Company fails to perform or observe any covenant
contained in this Indenture or in the Securities (other than a covenant, the
default in the performance or observance of which is specifically dealt with
elsewhere in this Section), and continuance of such default for a period of 30
days after there has been given to the Company by the Trustee or to the Company
and the Trustee by the Holders of not less than 25% in principal amount of the
Outstanding Securities a written notice specifying such default; or

Subsidiary, whether such Indebtedness now exists or is created, incurred or
assumed by the Company or a Company Subsidiary after the Initial Closing Date,
which default is (i) caused by a failure to pay when due and after the
expiration of any applicable grace period, the principal of, premium, if any, or
interest on such Indebtedness or (ii) or is caused by the failure to comply with
any covenant or condition contained in any such mortgage, indenture, loan
agreement or other instrument if the effect of such default is to entitle (after
giving effect to any applicable notice or cure rights) the holders of such
Indebtedness (or a trustee of or for such holders) to then cause such
Indebtedness to become due prior to its stated maturity, or result in the
acceleration of the maturity of such Indebtedness and, in each case, the
principal amount of any such Indebtedness, together with the principal amount of
any other such Indebtedness under which there is a default or the maturity of
which has been so accelerated; or

               (f) a final judgment or judgments (other than any judgment as to
which a reputable insurance company has accepted full liability) for the payment
of money in excess of $1,000,000

commencing thereof, or a court of competent jurisdiction enters an order under
any Bankruptcy Law that (i) is for relief against the Company or a Company

               SECTION 3.02. ACCELERATION. If an Event of Default (other than an
Event of Default specified in clauses (g) and (h) of Section 3.01 hereof) occurs
and is continuing, the Trustee by notice to the Company, or the Holders of not
less than a majority in principal amount of the Outstanding Securities by notice
to the Company and the Trustee, may declare all the Securities to be due and
payable. Upon such declaration, the principal of, premium, if any, and accrued
and unpaid interest on the Securities shall be due and payable immediately. If
an Event of Default specified in clause (g) or (h) of Section 3.01 hereof
occurs, such an amount shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder of the Securities. The Holders of a majority in aggregate principal
amount of the Outstanding Securities by notice to the Trustee may rescind an
acceleration and its consequences if the rescission would not conflict with any
judgment or decree and if all existing Events of Default have been cured or
waived except nonpayment of principal or interest that has become due solely
because of the acceleration.

               SECTION 3.03. OTHER REMEDIES. If an Event of Default occurs and
is continuing, the Trustee may pursue any available remedy to collect the
payment of principal, premium, if any, or interest on the Securities or to
enforce the performance of any provision of the Securities or this Indenture.

               The Trustee may maintain a proceeding for any right or remedy
available to it even if it does not possess any of the Securities or does not
produce any of them in the proceeding. A delay or omission by the Trustee or any
Holder in exercising any right or remedy accruing upon an Event of Default shall
not impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default. All remedies are cumulative to the extent permitted by law.

               SECTION 3.04. WAIVER OF PAST DEFAULTS. The Holders of a majority
in aggregate principal amount of the Outstanding Securities by notice to the
Trustee may waive an existing Default or Event of Default and its consequences
other than (i) a continuing Default or Event of Default in the payment of
principal of, or interest on, any Security or (ii) a Default or Event of Default
in respect of a provision that under Section 6.02 cannot be amended without the
consent of each Holder affected thereby. When a Default or Event of Default is
waived, it is cured and ceases; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon.

               SECTION 3.05. APPLICATION OF MONEY COLLECTED. Any money collected
by the Trustee pursuant to this Article III shall be applied in the following
order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on





                                       30
<PAGE>   37

account of principal, premium, if any, or interest, upon presentation of the
Securities, or both, as the case may be, and the notation thereon of the payment
if only partially paid and upon surrender thereof if fully paid:

               FIRST:  To the payment of all amounts due the Trustee
under Section 4.07;

               SECOND:  To the payment of all Senior Indebtedness to
the extent required by Article XI.

               THIRD: To the payment of the amounts then due and unpaid for
principal, premium, if any, interest or Additional Amounts on the Securities in
respect of which or for the benefit of which such money has been collected,
ratably, without preference or priority of any kind, according to the amounts
due and payable on such Securities for principal, premium, if any, interest or
Additional Amounts, respectively; and

               FOURTH:  Any remaining amounts shall be repaid to the
Company.

               SECTION 3.06. LIMITATION ON SUITS. No Holder of any Security
shall have any right to institute any proceeding, judicial or otherwise, with
respect to this Indenture, or for the appointment of a receiver or trustee, or
for any other remedy hereunder, unless:

               (a)  such Holder has previously given written notice to
the Trustee of a continuing Event of Default;

               (b) the Holders of not less than 25% in principal amount of the
Outstanding Securities shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default in its own name as
Trustee hereunder;

               (c) such Holder or Holders have offered to the Trustee reasonable
indemnity against the costs, expenses and liabilities to be incurred in
compliance with such request;

               (d) the Trustee for 60 days after its receipt of such notice,
request and offer of indemnity has failed to institute any such proceeding; and

               (e) no direction inconsistent with such written request has been
given to the Trustee during such 60 day period by the Holders of a majority in
principal amount of the Outstanding Securities;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or





                                       31
<PAGE>   38

to obtain or seek to obtain priority or preference over any other of such
Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all such Holders.

               SECTION 3.07. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE
PRINCIPAL, PREMIUM AND INTEREST AND TO CONVERT. Notwithstanding any other
provision in this Indenture, the Holder of any Security shall have the right,
which is absolute and unconditional, to receive payment of the principal of,
premium, if any, and (subject to Section 2.07) interest on such Security on the
respective Stated Maturities expressed in such Security (or, in the case of
redemption or repurchase, on the Redemption Date or Purchase Date, as the case
may be), and to convert such Security in accordance with Article X, and to
institute suit for the enforcement of any such payment and right to convert, and
such rights shall not be impaired without the consent of such Holder.

               SECTION 3.08. RESTORATION OF RIGHTS AND REMEDIES. If the Trustee
or any Holder of a Security has instituted any proceeding to enforce any right
or remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, or has been determined adversely to the Trustee or to
such Holder, then and in every such case, subject to any determination in such
proceeding, the Company, the Trustee and the Holders of Securities shall be
restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and such Holders shall
continue as though no such proceeding had been instituted.

               SECTION 3.09. RIGHTS AND REMEDIES CUMULATIVE. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities in the last paragraph of Section 2.06, each right or
remedy herein conferred upon or reserved to the Trustee or to the Holders of
Securities is not 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 hereafter
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 3.10. CONTROL BY HOLDERS OF SECURITIES. The Holders of a
majority in principal amount of the Outstanding Securities shall have the right
to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee; provided that




                                       32
<PAGE>   39

               (a)  such direction shall not be in conflict with any
rule of law or with this Indenture;

               (b)  such direction shall not be unduly prejudicial to
the rights of other holders of the Securities; and

               (c) the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction.

               SECTION 3.11. UNDERTAKING FOR COSTS. All parties to this
Indenture agree, and each Holder of any Security, 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 Indenture, or in
any suit against the Trustee for any action taken, suffered or omitted by it as
Trustee, 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 3.11 shall not apply to any suit instituted by the Company, to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities, or to any suit instituted by any Holder of any Security
for the enforcement of the payment of the principal of, premium, if any, or
interest on any Security or the payment of on or after the respective Stated
Maturity or Maturities expressed in such Security (or, in the case of redemption
or repurchase, on or after the Redemption Date or Repurchase Date, as the case
may be) or for the enforcement of the right to convert any Security in
accordance with Article X.

               SECTION 3.12. 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 hereafter in force, which may affect the covenants or the performance
of this indenture; and the Company (to the extent that it may lawfully do so)
hereby expressly waives all benefit 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 Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

               SECTION 3.13. COLLECTION SUIT BY TRUSTEE. If an Event of Default
specified in Section 3.01(a) or (b) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole





                                       33
<PAGE>   40

amount then due and owing (together with interest on any unpaid interest to the
extent lawful) and the amount provided for in Section 4.07.

               SECTION 3.14. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may
file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Holders of the
Securities allowed in any judicial proceedings relative to the Company, its
creditors or its property and, unless prohibited by law or applicable
regulations, may vote on behalf of the Holders in any election of a trustee in
bankruptcy or other Person performing similar functions, and any Custodian in
any such judicial proceeding is hereby authorized by each Holder to make
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due
the Trustee under Section 4.07.

                                   ARTICLE IV

                                   THE TRUSTEE

               SECTION 4.01.  CERTAIN DUTIES AND RESPONSIBILITIES.

               (a)  Except during the continuance of an Event of
Default,

                      (i)  the Trustee undertakes to perform such duties
and only such duties as are specifically set forth in this Indenture, and no
implied covenants or obligations shall be read into this Indenture against the
Trustee; and

                      (ii)  in the absence of bad faith on its part, the
Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture;
but in the case of any such certificates or opinions which by any provision
hereof are specifically required to be furnished to the Trustee, the Trustee
shall be under a duty to examine the same to determine whether or not they
conform to the requirements of this Indenture, but not to verify the contents
thereof.

               (b) in case an Event of Default has occurred and is continuing,
the Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.




                                       34
<PAGE>   41

               (c) No provision of this Indenture shall be construed to relieve
the Trustee from liability for its own negligent action, its own negligent
failure to act, or its own wilful misconduct, except that

                      (i)  this paragraph (c) shall not be construed to limit
the effect of paragraph (a) of this Section;

                      (ii) the Trustee shall not be liable for any error of 
judgment made in good faith by a Responsible Officer, unless it shall be proved
that the Trustee was negligent in ascertaining the pertinent facts;

                      (iii)  the Trustee shall not be liable with respect to 
any action taken or omitted to be taken by it in good faith in accordance with
the direction of the Holders of a majority in principal amount of the
Outstanding Securities relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred upon the Trustee, under this Indenture;

                      (iv)  no provision of this Indenture shall require
the Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it; and

                      (v)  whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the
provisions of this Section.

               SECTION 4.02. NOTICE OF DEFAULTS. Within 90 days after the
occurrence of any default hereunder, the Trustee shall give to all Holders of
Securities, in the manner provided in Section 1.06, notice of such Default known
to the Trustee, unless such Default shall have been cured or waived; provided,
however, that in the case of any Default of the character specified in Section
3.01(d), no such notice to Holders of Securities shall be given until at least
30 days after the occurrence thereof.

               SECTION 4.03.  CERTAIN RIGHTS OF TRUSTEE.  Subject to
the provisions of Section 4.01:

               (a) the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, Officers' Certificate, other
certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, debenture, note, other evidence of indebtedness or other
paper or





                                       35
<PAGE>   42

document believed by it to be genuine and to have been signed or presented by
the proper party or parties;

               (b) any request or direction of the Company mentioned herein
shall be sufficiently evidenced by a Company Request or Company Order and any
resolution of the Board of Directors shall be sufficiently evidenced by a Board
Resolution;

               (c) whenever in the administration of this Indenture the Trustee
shall deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;

               (d) the Trustee may consult with counsel of its selection and the
advice of such counsel or any opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon;

               (e)  the Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Indenture at the request or direction
of any of the Holders of Securities pursuant to this Indenture, unless such

against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction;

               (f) the Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, other evidence of indebtedness or other paper or document, but
the Trustee may make such further inquiry or investigation into such facts or
matters as it may see fit, and, if the Trustee shall determine to make such
further inquiry or investigation, it shall be entitled to examine the books,
records and premises of the Company, personally or by agent or attorney;

               (g) the Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder;

               (h) the permissive right of the Trustee to take or refrain from
taking any actions enumerated in this Indenture shall not be construed as a duty
and the Trustee shall not be answerable in such actions other than for its own
negligence or wilful misconduct; and




                                       36
<PAGE>   43

               (i) the Trustee shall not be liable for any action taken,
suffered or omitted to be taken by it in good faith and reasonably believed by
it to be authorized or within the discretion or rights or powers conferred upon
it by the Indenture.

               SECTION 4.04. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF
SECURITIES. The recitals contained herein and in the Securities (except the
Trustee's certificates of authentication) shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture, of the Securities, or of the Common Stock issuable upon the
conversion of the Securities. The Trustee shall not be accountable for the use
or application by the Company of Securities or the proceeds thereof.

               SECTION 4.05. MAY HOLD SECURITIES, ACT AS TRUSTEE UNDER OTHER
INDENTURES. The Trustee, any Authenticating Agent, any Paying Agent, any
Conversion Agent or any other agent of the Company or the Trustee, in its
individual or any other capacity, may become the owner or pledgee of Securities
and may otherwise deal with the Company with the same rights it would have if it
were not Trustee, Authenticating Agent, Paying Agent, Conversion Agent or such
other agent.

               The Trustee may become and act as trustee under other indentures
under which other securities, or certificates of interest or participation in
other securities, of the Company are outstanding in the same manner as if it
were not Trustee hereunder.

               SECTION 4.06. MONEY HELD IN TRUST. Money held by the Trustee in
trust hereunder need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed in writing with the
Company.

               SECTION 4.07.  COMPENSATION AND REIMBURSEMENT.  The Company 
agrees:

               (a) to pay to the Trustee from time to time such compensation as
the Company and the Trustee shall agree upon in a separate written agreement for
all services rendered by it hereunder;

               (b) except as otherwise expressly provided herein, to reimburse
the Trustee upon its request for all reasonable expenses, disbursements and
advances incurred or made by the Trustee in accordance with any provision of
this Indenture (including the reasonable compensation and the expenses and
disbursements of its agents and counsel), except any such





                                       37
<PAGE>   44

expense, disbursement or advance as may be attributable to its negligence or bad
faith; and

               (c) to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense incurred without negligence or bad faith
on its part, arising out of or in connection with the acceptance or
administration of this trust, including the reasonable costs, expenses and
reasonable attorneys' fees of defending itself against any claim or liability in
connection with the exercise or performance of any of its powers or duties
hereunder.

               To secure the Company's payment obligations in this Section 4.07,
each of the Trustee and the Paying Agent and the Registrar (if the Trustee is
acting in such capacities) shall have a lien prior to the Securities on all
money or property held or collected by it, in its capacity as Trustee, Paying
Agent or Registrar, as the case may be, except money or property held in trust
to pay principal of or interest on particular Securities. To the extent the same
entity serves in different capacities, it may assert the lien on its behalf in
relation to each of those capacities.

               When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 3.01(g) or Section
3.01(h), the expenses (including the reasonable charges of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

               The provisions of this Section shall survive the termination of
this Indenture.

               SECTION 4.08. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY;
DISQUALIFICATION; CONFLICTING INTEREST. Any Successor Trustee hereunder shall at
all times be a corporation duly organized, validly existing and in good standing
under the laws of the jurisdiction of its organization, authorized under such
laws to exercise corporate trust powers having a combined capital and surplus of
at least $1,000,000, subject to supervision or examination by federal or state
authority, in good standing and having an established place of business in the
Borough of Manhattan, The City of New York. If such successor Trustee publishes
reports of condition at least annually, pursuant to law or to the requirements
of said supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. Neither the Company nor any Person directly or
indirectly controlling, controlled by, or under common control with the Company
shall serve as Trustee. If at any time any successor Trustee shall cease to be
eligible in 





                                       38
<PAGE>   45

accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article and a
successor shall be appointed pursuant to Section 4.09.

               SECTION 4.09. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.
(a) No resignation or removal of the Trustee and no appointment of a successor
Trustee pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 4.10.

               (b) The Trustee may resign at any time by giving written notice
thereof to the Company. If the instrument of acceptance by a successor Trustee
required by Section 4.10 shall not have been delivered to the Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

               (c) The Trustee may be removed at any time by Act of the Holders
of a majority in principal amount of the Outstanding Securities, delivered to
the Trustee and the Company. If the instrument of acceptance by a successor
Trustee required by Section 4.10 shall not have been delivered to the Trustee
within 30 days after the giving of such notice of removal, the removed Trustee
may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

               (d)  if at any time:

                      (i)  the Trustee shall cease to be eligible under
Section 4.08 and shall fail to resign after written request therefor by the
Company or by any Holder of a Security who has been a bona fide Holder of a
Security for at least six months,

                      (ii)  the Trustee shall become incapable of acting
or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of
its property shall be appointed or any public officer shall take charge or
control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation,

then, in any such case (A) the Company by a Board Resolution may remove the
Trustee, or (B) subject to Section 3.11, any Holder of a Security who has been a
bona fide Holder of a Security for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor Trustee.



                                       40
<PAGE>   46

               (e) If the Trustee shall resign, be removed or become incapable
of acting, or if a vacancy shall occur in the office of Trustee for any cause,
the Company, by a Board Resolution, shall promptly appoint a successor Trustee
and shall comply with the applicable requirements of this Section and Section
4.10. If within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 4.10, become the successor Trustee
and supersede the successor Trustee appointed by the Company. If no successor
Trustee shall have been so appointed by the Company or the Holders of Securities
and accepted appointment in the manner required by this Section and Section
4.10, any Holder of a Security who has been a bona fide Holder of a Security for
at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

               (f) The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to all
Holders of Securities in the manner provided in Section 1.06. Each notice shall
include the name of the successor Trustee and the address of its Corporate Trust
Office.

               SECTION 4.10 ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. Every
successor Trustee appointed hereunder shall execute, acknowledge and deliver to
the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder. Upon request of any such successor Trustee, the
Company shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts.

               No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

               SECTION 4.11. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS. Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder;
provided such corporation shall be otherwise qualified and eligible under this
Article, without, the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

               SECTION 4.12. AUTHENTICATING AGENTS. The Trustee may, with the
consent of the Company, appoint an Authenticating Agent or Agents acceptable to
the Company with respect to the Securities which shall be authorized to act on
behalf of the Trustee to authenticate Securities issued upon exchange or
substitution pursuant to this Indenture.

               Securities authenticated by an Authenticating Agent shall be 
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder, and every reference
in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
subject to acceptance by the Company and shall at all times be a corporation
organized and doing business under the laws of the United States of America, any
State thereof, the District of Columbia, England and Wales, or Luxembourg,
authorized under such laws to act as Authenticating Agent and subject to
supervision or examination by government or other fiscal authority. If at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 4.12, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section 4.12.

               Any corporation into which an Authenticating Agent may be merged
or converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall



                                       41
<PAGE>   48


continue to be an Authenticating Agent; provided such corporation shall be
otherwise eligible under this Section 4.12, without the execution or filing of
any paper or any further act on the part of the Trustee or the Authenticating
Agent.

               An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 4.12, the Trustee may appoint a successor
Authenticating Agent which shall be subject to acceptance by the Company. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 4.12.

               The Company agrees to pay to each Authenticating Agent from time
to time reasonable compensation for its services under this Section 4.12.

               If an Authenticating Agent is appointed with respect to the
Securities pursuant to this Section 4.12, the Securities may have endorsed
thereon, in addition to or in lieu of the Trustee's certification of
authentication, an alternative certificate of authentication in the form
indicated by the bracketed text appearing in the form of certificate of
authentication attached to Exhibits A and B hereto.

all the properties and assets of the Company in accordance with Section 5.01,
the successor Person formed by such consolidation or into which the Company is
merged, or to which such conveyance, transfer, sale, lease or other disposition
is made, shall succeed to, and be substituted for, and may exercise every right
and power of, the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein, and thereafter, except in
the case of a conveyance, transfer, sale, lease or other disposition, the
predecessor Person shall be relieved of all obligations and covenants under this
Indenture and the Securities.

or accepting the additional trusts created by any supplemental indenture
permitted by this Article or the modifications thereby of the trusts created by

Sections 4.01 and 4.03) shall be fully protected in relying upon, an Opinion of
Counsel stating that the execution of such supplemental indenture is authorized
or permitted by this Indenture, that such supplemental indenture has been duly
authorized, executed and delivered by the Company and constitutes a valid and
legally binding obligation of the Company enforceable against the Company in

               SECTION 6.05. NOTATION ON OR EXCHANGE OF SECURITIES. Securities
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article may, and shall if required by the Trustee, bear a

modified as to conform, in the opinion of the Company and the Trustee, to any
such supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding
Securities.

               SECTION 6.06. NOTICE OF SUPPLEMENTAL INDENTURES. Promptly after

               SECTION 7.02.  CALL, NOTICE AND PLACE OF MEETING.

               (a) The Trustee may at any time call a meeting of Holders of
Securities for any purpose specified in Section 7.01, to be held at such time
and at such place in the Borough of Manhattan, The City of New York, or in the
City of London, England, as the Trustee shall determine. Notice of every meeting
of Holders of Securities, setting forth the time and the place of such meeting
and in general terms the action proposed to be taken at such meeting, shall be
given, in the manner provided in Section 1.06, not less than 21 nor more than
180 days prior to the date fixed for the meeting.

               (b) In case at any time the Company, pursuant to a Board
Resolution, or the Holders of at least 25% in principal amount of the
Outstanding Securities shall have requested the Trustee to call a meeting of the
Holders of Securities for any purpose specified in Section 7.01, by written
request setting forth in reasonable detail the action proposed to be taken at
the meeting, and the Trustee shall not have made the first publication of the
notice of such meeting within 21 days after receipt of such request or shall not
thereafter proceed to cause the meeting to be held as provided herein, then the
Company or the Holders of Securities in the amount specified, as the case may
be, may determine the time and the place in the Borough of Manhattan, The City
of New York, or in the City of London, England, for such meeting and may call
such meeting for such purposes by giving notice thereof as provided in paragraph

               SECTION 7.03. PERSONS ENTITLED TO VOTE AT MEETINGS. To be
entitled to vote at any meeting of Holders of Securities, a Person shall be (a)
a Holder of one or more Outstanding Securities or (b) a Person appointed by an
instrument in writing (valid under the laws of the State of New York) as proxy

representatives of the Trustee and its counsel and any representatives of the
Company and its counsel.

               SECTION 7.04. QUORUM; ACTION. The Persons entitled to vote a
majority in principal amount of the Outstanding Securities shall constitute a

period of not less than 10 days as determined by the chairman of the meeting
prior to the adjournment of such meeting. In the absence of a quorum at any such
adjourned meeting, such adjourned meeting may be further adjourned for a period

adjournment of such adjourned meeting (subject to repeated applications of this
sentence). Notice of the reconvening of any adjourned meeting shall be given as
provided in Section 7.02(a), except that such notice need be given only once not
less than five days prior to the date on which the meeting is scheduled to be
reconvened. Notice of the reconvening of an adjourned meeting shall state
expressly the percentage of the principal amount of the Outstanding Securities
which shall constitute a quorum.

               Subject to the foregoing, at the reconvening of any meeting
adjourned for a lack of a quorum, the Persons entitled to vote a majority in
principal amount of the Outstanding Securities at the time shall constitute a
quorum for the taking of any action set forth in the notice of the original
meeting.

               At a meeting or an adjourned meeting duly reconvened and at which
a quorum is present as aforesaid, any resolution and all matters (except as
limited by the proviso to Section 6.02) shall be effectively passed and decided
if passed or decided by the Persons entitled to vote not less than a majority in
aggregate principal amount of Outstanding Securities represented and entitled to
vote at such meeting.

               Any resolution passed or decisions taken at any meeting
of Holders of Securities duly held in accordance with this Section shall be
binding on all the Holders of Securities, whether or not present or represented
at the meeting. The Trustee shall, in the name and at the expense of the
Company, notify all the Holders of Securities of any such resolutions or
decisions pursuant to Section 1.06.

               SECTION 7.05.  DETERMINATION OF VOTING RIGHTS; CONDUCT
AND ADJOURNMENT OF MEETINGS.

               (a) Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any
meeting of Holders of Securities in regard to proof of the holding of Securities
and of the



                                       48
<PAGE>   55


appointment of proxies and in regard to the appointment and duties of inspectors
of votes, the submission and examination of proxies, certificates and other
evidence of the right to vote, and such other matters concerning the conduct of
the meeting as it shall deem appropriate. Except as otherwise permitted or
required by any such regulations, the holding of Securities shall be proved in
the manner specified in Section 1.04 and the appointment of any proxy shall be
proved in the manner specified in Section 1.04.

               (b) The Trustee shall, by an instrument in writing, appoint a
temporary chairman (which may be the Trustee) of the meeting, unless the meeting
shall have been called by the Company or by Holders of Securities as provided in
Section 7.02(b), in which case the Company or the Holders of Securities calling
the meeting, as the case may be, shall in like manner appoint a temporary
chairman. A permanent chairman and a permanent secretary of the meeting shall be
elected by vote of the Persons entitled to vote a majority in principal amount
of the Outstanding Securities represented at the meeting.

               (c) At any meeting, each Holder of a Security or proxy shall be
entitled to one vote for each $1,000 principal amount of Securities held or
represented by such Holder; provided, however, that no vote shall be cast or
counted at any meeting in respect of any Security challenged as not outstanding
and ruled by the chairman of the meeting to be not Outstanding. The chairman of
the meeting shall have no right to vote, except as a Holder of a Security or
proxy.

               (d) Any meeting of Holders of Securities duly called pursuant to
Section 7.02 at which a quorum is present may be adjourned from time to time by
Persons entitled to vote a majority in principal amount of the Outstanding
Securities represented at the meeting, and the meeting may be held as so
adjourned without further notice.


                                  ARTICLE VIII

                                    COVENANTS

               SECTION 8.01. PAYMENT COVENANT. The Company covenants and agrees
that it will duly and punctually pay the principal of, premium, if any, and
interest (including Additional Amounts) on the Securities, the Purchase Price
upon repurchase and the Redemption Price upon redemption, in each case, in
accordance with the terms of the Securities and this Indenture. The amount
payable by the Company in respect of any Principal



                                       49
<PAGE>   56


Payment Date shall be automatically reduced by the principal amount of all
Securities or portions thereof to be redeemed on such Principal Payment Date
which shall have been surrendered for conversion on or before the close of
business on such Principal Payment Date.

               SECTION 8.02. MAINTENANCE OF OFFICE OR AGENCY. The Company will
maintain (A) in the City and State of New York, an office or agency where
Securities may be presented or surrendered for payment, where Securities may be
surrendered for registration of transfer or for exchange, where Securities may
be presented for conversion and (B) subject to applicable laws and regulations,
in a city in Western Europe, and for so long as the Securities are listed on the
Luxembourg Stock Exchange, in Luxembourg, a Paying Agent, Transfer Agent and
Conversion Agent for the Securities. The Trustee will act as "Registrar" and
initially as principal Paying Agent, Conversion Agent and Transfer Agent for the
Securities. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of any such office or agency. If at
any time the Company shall fail to maintain any such required office or agency
in respect of the Securities or shall fail to furnish the Trustee with the
address thereof, such presentations, and surrenders of Securities may be made
and notices and demands may be made or served at the Corporate Trust Office of
the Trustee.

               The Company may also from time to time designate one or more
other offices or agencies where the Securities may be presented or surrendered
for any or all of such purposes specified above in this Section and may
constitute and appoint one or more Paying Agents, Transfer Agents or Conversion
Agents for the payment of such Securities, in one or more cities, and may from
time to time rescind such designations and appointments; provided, however, that
no such designation, appointment or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the places set
forth in this Section 8.02. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location
of any such other office or agency. Unless and until the Company rescinds one or
more such appointments, the Company hereby appoints Banque Internationale a
Luxembourg S.A. as its Luxembourg Paying Agent, Transfer Agent and Conversion
Agent.

               SECTION 8.03. MONEY FOR SECURITY PAYMENTS TO BE HELD IN TRUST.

               (a) If the Company shall at any time act as its own Paying Agent
for Securities, it will, on or before each due date of the principal of,
premium, if any, or interest on any of the Securities, segregate and hold in
trust for the benefit of the Persons entitled thereto a sum sufficient to pay
the principal of, premium, if any, or interest so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein



                                       50
<PAGE>   57


provided, and will promptly notify the Trustee of its action or failure so to
act.

               Whenever the Company shall have one or more Paying Agents, it
will, one Business Day prior to each due date of the principal of, premium, if
any, or interest (including Additional Amounts) on any Securities, deposit with
a Paying Agent, in immediately available funds, a sum sufficient to pay the
principal of, premium, if any, or interest (including any Additional Amounts) so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act.

               The Company will cause each Paying Agent to execute and deliver
to the Trustee an instrument in which such Paying Agent shall agree with the
Trustee subject to the provisions of this Section, that such Paying Agent will:

                      (i)  hold all sums held by it for the payment of
principal of, premium, if any, or interest (including Additional Amounts) on
Securities in trust for the benefit of the Persons entitled thereto until such
sums shall be paid to such Persons or otherwise disposed of as herein provided;

                      (ii)  give the Trustee notice of any Default by
the Company (or any other obligor upon the Securities) in the
making of any payment of principal, premium or interest on the
Securities; and

                      (iii)  at any time during the continuance of any
such Default, upon the written request of the Trustee, forthwith pay to the
Trustee all sums so held in trust by such Paying Agent.

               The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent, and, upon such payments by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

               Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of, premium, if
any, or interest on any Security and remaining unclaimed for two years after
such principal, premium 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



                                       51
<PAGE>   58


Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, may, at the
expense of the Company, cause to be published once, in an Authorized Newspaper
in each Place of Payment, notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

               (b) Any payment to be made in respect of the Securities by the
Company to, or to the order of, any Paying Agent shall be in satisfaction pro
tanto of the obligations of the Company under the Securities. The Company shall
indemnify the Holders against any failure on the part of any Paying Agent to pay
any sum due in respect of the Securities and shall pay such sum to the Trustee
on demand. This indemnity constitutes a separate and independent obligation from
the other obligations of the Company under the Securities, shall give rise to a
separate and independent cause of action, will apply irrespective of any waiver
granted by the Trustee or any Holder and shall continue in full force and effect
despite any judgment, order, claim, or proof for a liquidated amount in respect
of any sum due under the indenture, the securities or any judgment or order.

               (c) Notwithstanding the fact that a Paying Agent is not obligated
to make any such payment, if a Paying Agent pays out any amount due under the
terms of the Securities on or after the due date therefor on the assumption that
the corresponding payment for such amount has been or will be made by the
Company and such payment has in fact not been so made by the Company prior to
the time that such Paying Agent makes such payment, then the Company shall, on
demand, reimburse such Paying Agent for the relevant amount, and pay interest to
such Paying Agent on such amount from the date on which it is paid out to the
date of reimbursement at a rate per annum equal to the cost to the Paying Agent
of funding the amount paid out, as certified by such Paying Agent and expressed
as a rate per annum.

               SECTION 8.04. ADDITIONAL AMOUNTS. The Company will pay to the
Holder of any Security, Additional Amounts as provided in the forms of Security
set forth in Exhibits A and B hereto. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of, or interest on, or
in respect of, any Security, such mention shall be deemed to include mention of
the payment of Additional Amounts provided for in this Section to the extent
that, in such context, Additional Amounts are, were or would be payable in
respect thereof pursuant to the provisions of this Section and express mention
of the payment of Additional Amounts (if applicable) in any provisions hereof
shall not be



                                       52
<PAGE>   59


construed as excluding Additional Amounts in those provisions hereof where such
express mention is not made.

               At least 10 days prior to January 31, 1999, or an earlier
Redemption Date or Purchase Date (and at least 10 days prior to each date of
payment of principal or interest after such date or such earlier Redemption Date
or Repurchase Date, if there has been any change with respect to the matters set
forth in the below-mentioned Officers' Certificate), the Company will furnish
the Trustee and the Company's Luxembourg Paying Agent with an Officers'
Certificate instructing the Trustee and such Paying Agent whether such payment
of principal of, or interest on, the Securities shall be made to Holders of
Securities who are United States Aliens without withholding for, or on account
of, any tax, assessment or other governmental charge described in the forms of
Securities set forth in Exhibits A and B hereto. If any such withholding shall
be required, then such Officers' Certificate shall specify by country the
amount, if any, required to be withheld on such payments to such Holders of
Securities and the Company will pay to the Trustee or the Luxembourg Paying
Agent the Additional Amounts required by this Section to be paid in the event of
any such withholding. The Company covenants to indemnify the Trustee and any
Paying Agent for, and to hold them harmless against any loss, liability or
expense arising out of or in connection with actions taken or omitted by any of
them in reliance on any Officers' Certificate furnished pursuant to this
Section, except to the extent such loss, liability or expense is attributable to
the Trustee's negligence or bad faith.

               SECTION 8.05.  PAYMENT OF TAXES AND OTHER CLAIMS.  The Company
will promptly pay or discharge, and will cause each Company Subsidiary to pay or
discharge, before the same may become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or such Company
Subsidiary, and (2) all claims for labor, materials and supplies which, if
unpaid, might by law become a Lien or charge upon the property of the Company;
provided, however, that neither the Company nor any Company Subsidiary shall be
required to pay or discharge, or cause to be paid or discharged, any such tax,
assessment, charge or claim (i) whose amount, applicability or validity is being
contested in good faith by appropriate proceedings, or (ii) if the effect of
such failure to pay or discharge would not have a material adverse effect on the
assets, business, operations, properties or condition (financial or otherwise)
of the Company and the Company Subsidiaries taken as a whole.

               SECTION 8.06. STATEMENT BY OFFICERS AS TO DEFAULT. The Company
shall deliver to the Trustee within 120 days after the end of each fiscal year
of the Company an Officers' Certificate stating that in the course of
performance by the signatories of their duties as such officers of the Company
they



                                       53
<PAGE>   60


would normally obtain knowledge of whether any Default exists and whether the
Company has kept, observed, performed and fulfilled its obligations under this
Indenture. Such Certificate shall further state, as to each such Officer signing
such Certificate, to the best of the knowledge of such Officer, as of the date
of such Officers' Certificate, (a) whether any such Default or Event of Default
exists and is continuing, (b) whether the Company during the preceding fiscal
year, complied with each and every covenant and obligation of the Company under
this Indenture and the Securities and (c) whether any Default or Event of
Default occurred during such preceding fiscal year and is continuing as of the
date of such Officer's Certificate. If the Officers signing the Certificate know
of such a Default or Event of Default, whether then existing or occurring during
such preceding fiscal year, the Officers' Certificate shall describe such
Default and its status with particularity. The Company shall also promptly
notify the Trustee if the Company's fiscal year is changed so that the end
thereof is on any date other than the then current fiscal year end date.

               The Company will deliver to the Trustee, forthwith upon becoming
aware of the existence of a Default, Event of Default or material adverse change
in the financial condition or results of operations of the Company and the
Company Subsidiaries, on a consolidated basis, an Officers' Certificate
specifying with particularity such Default, Event of Default or material adverse
change and further stating what action the Company has taken, is taking or
proposes to take with respect thereto.

               SECTION 8.07. BOOKS AND RECORDS. The Company shall, and shall
cause each of the Company Subsidiaries to, keep its books, records and accounts
in accordance with GAAP applied on a basis consistent with preceding years.

               SECTION 8.08. MAINTENANCE OF INSURANCE. The Company shall
maintain, and shall cause each Company Subsidiary to maintain, with financially
sound and responsible insurers, insurance with respect to its properties and
business against such casualties and contingencies and in such amounts as are
customary in the case of similarly situated corporations engaged in the same or
similar business.

               SECTION 8.09. MAINTENANCE OF CORPORATE EXISTENCE, PROPERTIES,
ETC. Except to the extent otherwise permitted by this Indenture, the Company
shall, and shall cause each Company Subsidiary to, (i) do or cause or cause to
be done all things reasonably necessary to preserve, renew and keep in full
force and effect its corporate existence, except that any Company Subsidiary may
merge with or into the Company or any other Company Subsidiary so long as the
surviving corporation of the Merger is the Company or a Company Subsidiary; (ii)
at all times maintain, preserve and protect all of its patents, trademarks,



                                       54
<PAGE>   61



service marks, trade names, service names, copyrights, licenses, permits
franchises and other rights, including distributorship and franchise agreements,
that continue to be useful in some material respect in the conduct of its
business; and (iii) preserve all the remainder of its property useful in the
conduct of its business and keep the same in good repair, working order and
condition (ordinary wear and tear excepted), and 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, that nothing in this Section 8.09 shall prevent the Company or any
Company Subsidiary from discontinuing the use, operation or maintenance of any
of such properties, or disposing of any of them, if such discontinuance or
disposal is, in the judgment of the Board of Directors or the board of directors
of such Company Subsidiary, or of any executive officer of the Company or such
Company Subsidiary, as applicable, having managerial responsibility for any such
property, desirable in the conduct of the business of the Company or such
Company Subsidiary.

               SECTION 8.10 TYPE OF BUSINESS. The Company shall, and shall cause
each Company Subsidiary to, remain in substantially the same businesses in which
the Company and the Company Subsidiaries are engaged as of the date of this
Indenture or in other types of businesses reasonably related or incidental
thereto, except to the extent that any such business of the Company or any
Company Subsidiary is continued by the Company or any other Company Subsidiary.

               SECTION 8.11. INVESTMENTS. The Company shall not, and shall not
permit any Company Subsidiary to, make or have outstanding any loan or advance
to, or own purchase or acquire any obligations (other than accounts receivable
generated in the ordinary course of business) or Securities of, or any interest
in, or make any capital contribution to or acquire all or substantially all of
the assets of, any other Person, other than: (a) strategic investments which in
the good faith business judgment of the Board of Directors of the Company or the
board of directors of the Company Subsidiary which proposes to make such
investment, as the case may be, are in furtherance of the business purposes of
the Company or the Company Subsidiary making such investment; (b) endorsement of
negotiable instruments for collection or deposit in the ordinary course of
business; (c) ownership of stock of the Company Subsidiaries; and (d) redemption
of the Securities as permitted by the Securities under this Indenture.

from the sale of the Securities as specified in the Offering Memorandum pursuant
to which the Securities were offered for sale.



                                       55
<PAGE>   62


               SECTION 8.13. DIVIDENDS, ETC. The Company will not declare or pay
any dividend on its capital stock (other than stock dividends), and, except as
expressly permitted by this Indenture and the Securities, the Company will not,
and will not permit any Company Subsidiary, to purchase, redeem, retire or
acquire any capital stock or securities of the Company, such Company Subsidiary
or another Company Subsidiary which is, directly or indirectly, convertible into
or exchangeable for capital stock of the Company, such Company Subsidiary or
another Company Subsidiary, or subordinated debt of the Company or such Company
Subsidiary or another Company Subsidiary (except in accordance with the
mandatory provisions of any securities which are or constitute convertible
securities or subordinated indebtedness of any such corporations), or any
option, warrant or other right of the Company to acquire any such capital stock,
convertible securities or subordinated debt; provided that the Company may
exercise its option pursuant to its July 1997 Shareholder Agreements with
certain employee-shareholders to purchase shares of Common Stock of the Company
held by any such shareholder upon death or termination of employment of such
shareholder, provided that at the time the Company may seek to exercise any such
option no Default or Event of Default shall have occurred and be continuing and
immediately after giving effect to the exercise by the Company of such option,
no Default or Event of Default shall have occurred and be continuing.

               SECTION 8.14. COMPLIANCE WITH LAWS, ETC. The Company will comply,
and will cause each of the Company Subsidiaries to comply, in all material
respects with all Requirements of Law and Contractual Obligations applicable to
or binding upon any of them.

               SECTION 8.15. TRANSACTIONS WITH AFFILIATES. The Company will not,
and will not permit any Company Subsidiary to, directly or indirectly purchase,
acquire or lease any property from, or sell, transfer or lease any property to,
or otherwise deal with, in the ordinary course of business or otherwise, any
Affiliate, except (a) upon terms not less favorable to Company or the Company
Subsidiary than if the Affiliate relationship did not exist and provided the
transaction is approved by a majority of the Independent Directors of the Board
of Directors of the Company; and (b) for the transactions and obligations
disclosed under "Certain Relationships and Related Transactions" in the
Company's Proxy Statement for its 1998 Annual Meeting of Shareholders.

               SECTION 8.16. LIMITATION ON LIENS. If the Company or any Company
Subsidiary shall at any time create, incur, assume or permit to exist any Lien
on any assets of the Company or such Company Subsidiary or any income or profits
therefrom, then the Company shall, prior to or simultaneously with the creation,
incurrence, assumption or commencement of existence of such Lien,



                                       56
<PAGE>   63


secure or cause to be secured the due and punctual payment of the principal of,
premium, if any, and interest on, and the Redemption Price and Purchase Price in
respect of the Securities, equally and ratably with any and all indebtedness
secured by such Lien; provided, however, that this covenant shall not apply in
the case of Liens arising in the ordinary course of business of the Company or a
Company Subsidiary, as applicable, or Liens on any assets of the Company or a
Company Subsidiary securing Senior Indebtedness.


                                   ARTICLE IX

                                   REDEMPTION

               SECTION 9.01. SELECTION OF SECURITIES TO BE REDEEMED. If the
Company, as permitted by the terms of the Securities, shall establish a
Redemption Date for the Securities, then, if less than all the Securities are to
be redeemed (as expressly permitted by the form of Securities set forth as
Exhibits A and B hereto), the Trustee shall select the Securities to be redeemed
on a pro rata basis, by lot or by such method as the Trustee shall deem fair and
appropriate. The Trustee shall make the selection not more than 60 days and not
less than 30 days before the Redemption Date from Outstanding Securities not
previously called for redemption. The Trustee may, by such method as it shall
deem fair and appropriate, select for redemption portions of the principal of
Securities that have denominations of $10,000 or integral multiples thereof.
Provisions of this Indenture that apply to Securities called for redemption also
apply to portions of Securities called for redemption. The Trustee shall notify
the Company promptly of the Securities or portions of Securities to be called
for redemption.

               If any Security selected for partial redemption is converted in
part after such selection, the converted portion of such Security shall be
deemed (so far as may be) to be the portion to be selected for redemption. The
Securities (or portions thereof) so selected shall be deemed duly selected for
redemption for all purposes hereof, notwithstanding that any such Security is
converted in whole or in part before the mailing of the notice of redemption.
Upon any redemption of less than all the Securities, the Company and the Trustee
may treat as an Outstanding Security any Security surrendered for conversion
during the period 15 days preceding the mailing of a notice of redemption and
need not treat as an Outstanding Security any Security authenticated and
delivered during such period in exchange for the unconverted portion of any
Security converted in part during such period.



                                       57
<PAGE>   64

               SECTION 9.02. NOTICE OF REDEMPTION. At least 30 days but not more
than 60 days before a Redemption Date, the Company shall give notice of
redemption in accordance with Section 1.06.

               All notices of redemption shall identify the Securities to be
redeemed and shall state:

               (a)  the Redemption Date;

               (b)  the Redemption Price;

               (c) if any Security is being redeemed in part, (i) the portion of
the principal amount of such Security to be redeemed and the aggregate principal
amount of Outstanding Securities after such partial redemption, (ii) the last
date on which exchanges or registration of transfers of Securities may be made
pursuant to Section 2.05 hereof and (iii) the serial numbers of the Securities
and the portions thereof called for redemption and that, after the Redemption
Date, upon cancellation of such Security, a new Security or Securities in
principal amount equal to the unredeemed portion will be issued in the name of
the Holder thereof;

               (d) the then current Conversion Price and the date on which the
right to convert Securities or portions thereof to be redeemed will expire and
the places where such Securities may be surrendered for conversion;

               (e)  the names and addresses of the Paying Agents;

               (f) that Securities called for redemption must be surrendered to
a Paying Agent outside the United States to collect the Redemption Price plus
accrued and unpaid interest;

               (g) on the Redemption Date, the Redemption Price and interest on
the Securities to be redeemed, accrued through the Redemption Date, will become
due and payable and that, unless the Company defaults in making such redemption
payment or the Paying Agents are prohibited from making such payment pursuant to
the terms of this Indenture, interest on Securities called for redemption ceases
to accrue on and after the earlier of the Redemption Date and the Conversion
Date;

               At the Company's request, the Trustee shall give notice of
redemption in the Company's name and at its expense.

               SECTION 9.03. EFFECT OF NOTICE OF REDEMPTION. Once notice of
redemption is mailed or otherwise provided, Securities called for redemption
become due and payable on the Redemption Date at the Redemption Price set forth
in the Security.



                                       58
<PAGE>   65

               SECTION 9.04. DEPOSIT OF REDEMPTION PRICE. Prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 8.03) money sufficient to pay the Redemption
Price of, and accrued interest up to, but not including, such Redemption Date,
in respect of, all Securities to be redeemed on such date (subject to the right
of holders of record on the relevant Record Date to receive interest due on an
Interest Payment Date) unless such Securities have theretofore converted into
Common Stock pursuant to the provisions hereof. The Trustee or such Paying Agent
shall return to the Company any money not required for that purpose.

               SECTION 9.05. SECURITIES REDEEMED IN PART. Upon cancellation of a
Security that is redeemed in part, the Company shall issue and the Trustee shall
authenticate for the Holder at the expense of the Company a new Security equal
in principal amount to the unredeemed portion of the Security surrendered.

               SECTION 9.06. PAYMENT OF REDEMPTION PRICE. In the event of a
redemption of Securities by the Company, the Company shall pay or cause to be
paid to the Trustee or any Paying Agent the Redemption Price; provided, however,
that installments of interest that mature on or prior to the Redemption Date
shall be payable in cash to the Holders of Securities to be redeemed, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Regular Record Date according to the terms and provisions of Article
II.


                                    ARTICLE X

                                   CONVERSION

               SECTION 10.01. CONVERSION RIGHT. A Holder of a Security may
convert the principal amount thereof (or any portion thereof that is an integral
multiple of $1,000) into fully paid and nonassessable shares of Common Stock of
the Company ("Conversion Shares") at any time on or after November 30, 1998 and
prior to the close of business (New York time) on the date of Maturity of such
Security, at the Conversion Price then in effect, except that, with respect to
any Security called for redemption or repurchase, such conversion right shall
terminate at the close of business on the Redemption Date or the Purchase Date,
as the case may be. The number of shares of Common Stock issuable upon
conversion of a Security shall be determined by dividing the principal amount of
the Security to be converted by the conversion price in effect on the Conversion
Date (the "Conversion Price").



                                       59
<PAGE>   66


               The initial Conversion Price is stated in the forms of the
Securities set forth in the Exhibits A and B hereto and is subject to adjustment
as provided in this Article X.

               Provisions of this Indenture that apply to conversion of all of a
Security also apply to conversion of a portion of it. A Holder of Securities is
not entitled to any rights of a holder of Conversion Shares until such Holder of
Securities has converted such Securities into Conversion Shares, and only to the
extent that such Securities are deemed to have been converted into Conversion
Shares under this Article X.

               SECTION 10.02. CONVERSION PRIVILEGE. To convert a Security, a
Holder must (1) complete and sign a notice of election to convert substantially
in the forms set forth in Exhibits A and B hereto (each, a "Conversion Notice"),
(2) surrender the Security to a Conversion Agent, (3) furnish appropriate
endorsements or transfer documents if required by the Registrar, Transfer Agent
or Conversion Agent and (4) pay any transfer or similar tax, if required. The
date on which the Holder satisfies all of those requirements is the conversion
date (the "Conversion Date"). As soon as practicable after the Conversion Date,
the Company shall deliver to the Holder through the Conversion Agent, a
certificate for the number of whole Conversion Shares issuable upon such
conversion and a check for any fractional Conversion Share determined pursuant
to Section 10.04 and (except as provided in the next paragraph) for interest on
such Security accrued through the Conversion Date. The person in whose name the
certificate for Conversion Shares is to be registered shall become the
shareholder of record on the Conversion Date and, as of the Conversion Date, the
rights of the Holder of the Securities shall cease as to the portion thereof so
converted; provided, however, that no surrender of a Security on any date when
the stock transfer books of the Company shall be closed shall be effective to
constitute the Person entitled to receive the Conversion Shares upon such
conversion as the shareholder of record of such shares of Common Stock on such
date, but such surrender shall be effective to constitute the Person entitled to
receive such Conversion Shares as the shareholder of record thereof for all
purposes at the close of business on the next succeeding day on which such stock
transfer books are open; provided further that such conversion shall be at the
Conversion Price in effect on the date that such Security shall have been
surrendered for conversion, as if the stock transfer books of the Company had
not been closed.

               No payment or adjustment will be made in respect of dividends or
distributions on Conversion Shares. If any Holder surrenders a Security for
conversion after the close of business on the Record Date for the payment of an
installment of interest and prior to the opening of business on the next
Interest Payment Date, then, notwithstanding such conversion, the interest
payable on such Interest Payment Date shall be paid to the Holder of such



                                       60
<PAGE>   67



Security on such Record Date. In such event, such Security, when surrendered for
conversion, must be accompanied by payment in funds acceptable to the Company of
an amount equal to the interest payable on such Interest Payment Date on the
portion so converted.

               If a holder converts more than one Security at the same time, the
number of whole Conversion Shares issuable shall be based on the total principal
amount of Securities converted.

               Upon surrender of a Security that is converted in part, the
Trustee shall authenticate for the Holder a new Security equal in principal
amount to the unconverted portion of the Security surrendered.

               SECTION 10.03. PARTIAL CONVERSION

               In the case of any Security which is converted in part only, upon
such conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Security or
Securities of authorized denomination in an aggregate principal amount equal to
the unconverted portion of the principal amount of such Security. A Security may
be converted in part, but only if the principal amounts of such Security, both
to be converted and to remain Outstanding after such conversion, equal
U.S.$10,000 or an integral multiple thereof.

               SECTION 10.04. FRACTIONS OF SHARES.

               No fractional Conversion Shares shall be issued upon conversion
of any Security. Instead of any fractional Conversion Share which would
otherwise be issuable upon conversion of any Security, the Company shall
calculate and pay a cash adjustment in respect of such fraction (calculated to
the nearest 1/100th of a Share) in an amount equal to the same fraction of the
Conversion Price per Conversion Share at the close of business on the Conversion
Date.

               SECTION 10.05. TAXES ON CONVERSIONS.

               The issuance of certificates for Conversion Shares upon the
conversion of any Security shall be made without charge to the converting Holder
for such certificates or for any tax in respect of the issuance of such
certificates, and such certificates shall be issued in the respective names of,
or in such names as may be directed by, the Holder or Holders of the converted
Security; provided, however, that in the event that certificates for Conversion
Shares are to be issued in a name other than the name of the Holder of the
Security converted, such Security, when surrendered for conversion, shall be
accompanied by an instrument of transfer, in form satisfactory to the



                                       61
<PAGE>   68


Company, duly executed by the Holder thereof or his duly authorized attorney;
and provided further, moreover, that the Company 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 such certificates in a name other than that of the Holder of
the converted Security, and the Company shall not be required to issue or
deliver such certificates unless or until the person or persons requesting the
issuance thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid
or is not applicable.

               SECTION 10.06. ADJUSTMENT OF CONVERSION PRICE.

               (a) In case the Company shall pay or make a dividend or other
distribution to all holders of any class of its capital stock in shares of
Common Stock, the Conversion Price in effect at the opening of business on the
day next following the date fixed for the determination of shareholders entitled
to receive such dividend or other distribution shall be reduced by multiplying
such Conversion Price by a fraction, of which the numerator shall be the number
of shares of Common Stock outstanding at the close of business on the date fixed
for such determination, and the denominator shall be the sum of the numerator
and the total number of shares constituting such dividend or other distribution,
such reduction to become effective immediately after the opening of business on
the day next following the date fixed for such determination. For the purposes
of this Section 10.06(a), the number of shares of Common Stock at any time
outstanding shall not include shares of Common Stock held in the treasury of the
Company. The Company will not pay any dividend or make any distribution on
shares of Common Stock held in the treasury of the Company.

               (b) In case the Company shall (by dividend or otherwise)
distribute to all holders of its Common Stock evidences of indebtedness or
assets (including stock or other securities and cash of the Company or any other
issuer, but excluding any regular cash dividends paid out of earned surplus and
any dividend or distribution referred to in Section 10.06(a)), the Conversion
Price shall be reduced so that the same shall equal the product of multiplying
the Conversion Price in effect immediately prior to the effectiveness of the
Conversion Price reduction contemplated by this Section 10.06(b) by a fraction,
of which the numerator shall be the current market price per share (determined
as provided in the next paragraph of this Section 10.06(b)) of the Common Stock
on the date of such effectiveness less the then fair market value of the portion
of the evidences of indebtedness or assets so distributed applicable to one
share of Common Stock, and the denominator shall be such current market price
per share of the Common Stock. Such reduction shall become effective immediately
prior to the opening of business on the day next following the date fixed for
the



                                       62
<PAGE>   69


payment of such distribution. Each reference to "fair market value" in this
Section 10.06 shall mean fair market value as reasonably determined in good
faith by the Board of Directors, whose determination shall be conclusive and
described in a Board Resolution filed with the Trustee.

               For the purpose of any computation under this Section 10.06, the
"current market price per share" of Common Stock on any date shall be calculated
by the Company and be deemed to be the average of the Daily Closing Prices Per
Share for each of the five consecutive Trading Days selected by the Company
commencing not more than 10 Trading Days before, and ending not later than, the
earlier of the day in question and the day before the "ex date" with respect to
any issuance or distribution requiring such computation. For purposes of this
paragraph, the term "ex date", when used with respect to any issuance or
distribution, means the first date on which the Common Stock trades regular way
on the applicable securities exchange or in the applicable securities market
without the right to receive such issuance or distribution.

               (c) In case the outstanding shares of Common Stock shall be
subdivided into a greater number of shares of Common Stock, the Conversion Price
in effect at the opening of business on the day following the day upon which
such subdivision becomes effective shall be proportionately reduced, and,
conversely, in case the outstanding shares of Common Stock shall each be
combined into a smaller number of shares of Common Stock, the Conversion Price
in effect at the opening of business on the day following the day upon which
such combination becomes effective shall be proportionately increased, such
reduction or increase, as the case may be, to become effective immediately after
the opening of business on the day following the day upon which such subdivision
or combination becomes effective.

               (d) If the Company shall issue or sell any shares of Common Stock
for a consideration per share less than the current market price per share in
effect immediately prior to the time of such issue (determined as provided in
Section 10.06(b)) or sale or for no consideration (excluding any event set forth
in Section 10.06 (a) or (b)), then, forthwith upon such issue or sale, the
Conversion Price shall be reduced to the consideration per share received by the
Company for the shares of Common Stock issued or sold; provided, however, that
the Conversion Price shall not be reduced by reason of (i) the exercise of any
options or warrants to purchase Common Stock which (A) are outstanding on the
date hereof or (B) are granted hereafter pursuant to a stock incentive plan for
the benefit of employees of the Company and Company Subsidiaries which has been
or may be adopted by the stockholders of the Company; or (ii) the issue or grant
of the options referred to in clause (i)(B) above; or (iii) any shares of Common
Stock, Convertible Securities or options or warrants to subscribe for or
purchase Common Stock or Convertible Securities issued by



                                       63
<PAGE>   70


the Company as consideration for the acquisition by the Company or any Company
Subsidiary of a controlling interest in another corporation or all or
substantially all of its assets by merger, purchase or otherwise. In no event
shall the Conversion Price be adjusted so that the Conversion Price per share is
less than the par value per share of the Common Stock.

               For purposes of this Section 10.06(d), the following shall be
applicable:

               (1) If the Company 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 warrants or options for the purchase of Common Stock or any
capital stock or securities convertible into or exchangeable for shares of
Common Stock (such convertible or exchangeable stock or securities being herein
called "Convertible Securities"), whether or not such rights, warrants or
options or the right to convert or exchange any such Convertible Securities are
immediately exercisable, and the price per share for which shares of Common
Stock are issuable upon the exercise of such rights, warrants or options or upon
conversion or exchange of such Convertible Securities shall be less than the
current market price per share in effect immediately prior to the time of the
granting of such rights, warrants or options, as the case may be, then the total
maximum number of shares of Common Stock issuable upon the exercise of such
rights, warrants or options or upon conversion or exchange of all such
Convertible Securities issuable upon the exercise of such rights, warrants or
options shall be deemed to be issued as of the date of the issuance of such
rights, warrants or options and the reduction set forth in Section 10.06(d), if
any, shall be effected as of such date. For the purpose of the preceding
sentence, the price per share for which shares of Common Stock are issuable upon
exercise of rights, warrants or options of the type described in the preceding
sentence or upon conversion or exchange of such Convertible Securities shall be
determined by dividing (i) the total amount (in each case as determined in good
faith by the Board of Directors pursuant to Section 10.06(d)(4)), if any,
received or receivable by the Company as consideration for the granting of such
rights, warrants or options, plus the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the exercise of such rights,
warrants or options, or plus, in the case of such rights, warrants or 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 (ii) the
total number of shares of Common Stock issuable upon the exercise of such
rights, warrants or options or upon the conversion or exchange, at such time of
all such Convertible Securities issuable upon the exercise of such rights,
warrants or options. Except as provided in clause (3) below, no further
adjustment of the Conversion Price shall be made upon the actual issue of such
shares of



                                       64
<PAGE>   71


Common Stock or of such Convertible Securities upon exercise of such rights,
warrants or options or upon the actual issuance of such shares of Common Stock
upon conversion or exchange of such Convertible Securities.

               (2) If the Company shall in any manner issue (whether directly or
by assumption in a merger or otherwise) or sell any Convertible Securities,
whether or not the right to exchange or convert thereunder is immediately
exercisable, and the price per share for which shares of Common Stock are
issuable upon such conversion or exchange (determined by dividing (i) the total
amount, if any, received or receivable by the Company as consideration for the
issue or sale of such Convertible Securities, plus the minimum aggregate amount
of additional consideration, if any, payable to the Company upon the conversion
or exchange thereof, by (ii) 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 current market price per share 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 be issued as of the date of the issuance of such
Convertible Securities and the reduction set forth in Section 10.06(d), if any,
shall be effected as of such date, (a) except as otherwise provided in clause
(3) below, no further adjustment of the Conversion Price shall be made upon the
actual issue of such shares of Common Stock upon conversion or exchange of such
Convertible Securities, and (b) if any such issue or sale of such Convertible
Securities is made upon exercise of any rights to subscribe for or to purchase
or any warrant or option to purchase any such Convertible Securities for which
adjustments of the Conversion Price have been or are to be made pursuant to the
provisions of clause (1) above, no further adjustment of the Conversion Price
shall be made by reason of such issue or sale.

               (3) Upon the happening of any of the following events, namely, if
the purchase price provided for in any right, warrant or option referred to in
clause (1) above, or the additional consideration, if any, payable upon the
conversion or exchange of any Convertible Securities referred to in clauses (1)
or (2) above, or the rate at which any Convertible Securities referred to in
clauses (1) or (2) above are convertible into or exchangeable for shares of
Common Stock, shall change (other than under or by reason of provisions designed
to protect against dilution), the Conversion Price then in effect hereunder
shall forthwith be readjusted (increased or decreased, as the case may be) to
the Conversion Price which would have been in effect at such time had such
rights, warrants or 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 they had initially been granted, issued or sold. On
the expiration of any such option or right referred to



                                       65
<PAGE>   72


in clause (1) above, or the termination of any such right to convert or exchange
any such Convertible Securities referred to in clauses (1) or (2) above, the
Conversion Price then in effect hereunder shall forthwith be readjusted
(increased or decreased, as the case may be) to the Conversion Price which would
have been in effect at the time of such expiration or termination had such
right, warrant, option or Convertible Securities, to the extent outstanding
immediately prior to such expiration or termination, never been granted, issued
or sold, and the shares of Common Stock issuable thereunder shall no longer be
deemed to be outstanding. If the purchase price provided for in any such right
or option referred to in clause (1), or the rate at which any Convertible
Securities referred to in clauses (1) or (2) are convertible into or
exchangeable for shares of 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 shares of Common Stock upon the
exercise of any such right, warrant or option or upon conversion or exchange of
any such Convertible Securities, the Conversion Price then in effect hereunder
shall, if not already adjusted, forthwith be adjusted to such amount as would
have been obtained had such right, warrant, option or Convertible Securities
never been issued as to such shares of Common Stock and had adjustments been
made upon the issuance of such shares of Common Stock delivered as aforesaid,
but only if as a result of such adjustment the Conversion Price then in effect
hereunder is thereby reduced.

               Notwithstanding the foregoing, if an adjustment has been made to
the Conversion Price as a result of the issuance of any class of rights,
warrants, options or Convertible Securities, and a portion of such class has
been exercised, converted or exchanged, then no increase in the Conversion Price
shall be made by reason of a subsequent change in the purchase price, or
conversion rate, as the case may be, or the expiration, of any such rights,
options or Convertible Securities remaining outstanding.

               (4) In case at any time shares of Common Stock or Convertible
Securities or any rights, warrants or options to purchase shares of Common Stock
or Convertible Securities, shall be issued or sold for cash, the consideration
therefor shall be the amount of such cash consideration. In case at any time any
shares of Common Stock, Convertible Securities or any rights, warrants or
options to purchase any such shares of Common Stock or Convertible Securities
shall be issued or sold for consideration other than cash, the amount of the
consideration other than cash received by the Company shall be deemed to be the
fair value of such consideration, as determined reasonably and in good faith by
the Board of Directors.

               (5) In case at any time any shares of Common Stock, Convertible
Securities or any rights, warrants or options to



                                       66
<PAGE>   73


purchase any shares of Common Stock or Convertible Securities shall be issued in
connection with any merger or consolidation in which the Company is the
surviving corporation, the amount of consideration received therefor shall be
deemed to be the fair market value, of such portion of the assets and business
of the nonsurviving corporation as the Board of Directors may reasonably
determine in good faith to be attributable to such shares of Common Stock,
Convertible Securities, rights or options, as the case may be.

               (6) In case at any time any rights, warrants or options to
purchase any shares of Common Stock or Convertible Securities shall be issued in
connection with the issue and sale of other securities of the Company, together
comprising one integral transaction in which no consideration is allocated to
such rights or options by the parties thereto, such rights, warrants or options
shall be deemed to have been issued without consideration; and if a specific
amount of consideration is allocated to such rights, warrants or options, such
rights, warrants or options shall be deemed to have been issued for such
consideration.

               (7) In the event of any consolidation or merger of the Company in
which stock or securities of another corporation are issued in exchange for
Common Stock of the Company or in the event of any sale of all or substantially
all of the assets of the Company in exchange for stock or other securities of
another corporation, the Company shall be deemed to have issued a number of
shares of its Common Stock for stock or securities of the other corporation
computed on the basis of the actual exchange ratio on which the transaction was
predicated and for a consideration equal to the fair market value on the date of
such transaction of such stock or securities of the other corporation, as
reasonably determined in good faith by the Board of Directors, and if any such
calculation results in adjustment of the Conversion Price, the determination of
the number of Conversion Shares receivable upon conversion of this Security
immediately prior to such merger, consolidation or sale, for purposes of Section
10.12, shall be made after giving effect to such adjustment of the Conversion
Price.

               (e) In case the Company shall fail to take a record of the
holders of its shares of Common Stock for the purpose of entitling them (i) to
receive a dividend or other distribution payable in shares of Common Stock or
Convertible Securities, or (ii) to subscribe for or purchase shares of Common
Stock 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 or Convertible
Securities deemed to have been issued or sold as a result of 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.

               SECTION 10.07. NO ADJUSTMENT UNDER CERTAIN CIRCUMSTANCES. No
adjustment in the Conversion Price shall be required unless such adjustment
would require an increase or decrease of at least one percent (1%) in the
Conversion Price; provided, however, that any adjustments which by reason of
this Section 10.07 are not required to be made shall be carried forward and
taken into account in any subsequent adjustment.

               SECTION 10.08. OTHER ADJUSTMENTS. In the event that, as a result
of an adjustment made pursuant to Section 10.06 hereof, the holder of any
Security thereafter surrendered for conversion shall become entitled to receive
any shares of capital stock of the Company other than shares of its Common
Stock, then, thereafter, the Conversion Price of such other shares so receivable
upon conversion of any Securities shall be subject to adjustment from time to
time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to Common Stock contained in this Article X.

               SECTION 10.09. ADJUSTMENTS FOR TAX PURPOSES. The Company may, at
its option, make such reductions in the Conversion Price, in addition to those
required by Section 10.06 hereof, as it determines to be advisable in order that
any stock dividend, subdivision of shares of Common Stock, distribution of
rights to purchase Common Stock or Convertible Securities or distribution of
Convertible Securities made by the Company to holders of Common Stock will not
be taxable to the recipients thereof.

               SECTION 10.10 NOTICE OF ADJUSTMENT. Whenever the Conversion Price
is adjusted, the Company shall give notice to the Holders in accordance with
Section 1.06 and file with the Trustee an Officers' Certificate briefly stating
the facts requiring the adjustment and the manner of computing it. The
certificate shall be conclusive evidence of the correctness of such adjustment.
Copies of such notice will be available to Holders on request at the office of
each Conversion Agent.

               SECTION 10.11.  NOTICE OF CERTAIN TRANSACTIONS.  In the event 
that:

                  (1) the Company takes any action which would require an 
adjustment in the Conversion Price;

                      (2)  the Company takes any action that would require a 
supplemental indenture pursuant to Section 10.12; or

                      (3)  there is a dissolution or liquidation of the 
Company;

a Holder of a Security may wish to convert such Security into shares of Common
Stock prior to the record date for or the



                                       68
<PAGE>   75


effective date of the transaction so that he may receive the rights, warrants,
securities or assets which a holder of shares of Common Stock on that date may
receive. Therefore, the Company shall give notice to the Holders in accordance
with Section 1.06 and to the Trustee stating the proposed record or effective
date, as the case may be. Failure to give such notice or any defect therein
shall not affect the validity of any transaction referred to in clause (1), (2)
or (3) of this Section 10.11.

               SECTION 10.12.  EFFECT OF RECLASSIFICATIONS, CONSOLIDATIONS, 
MERGERS OR SALES OF ASSETS. If any of the following shall occur, namely:

               (a) any reclassification or change of outstanding shares of
Common Stock issuable upon conversion of Securities (other than a change in par
value, or from par value to no par value, or from no par value to par value, or
as a result of a subdivision or combination);

               (b) any consolidation or merger to which the Company is a party
other than a merger in which the Company is the continuing corporation and which
does not result in any reclassification of, or change (other than a change in
name, or par value, or from par value to no par value, or from no par value to
par value or as a result of a subdivision or combination) in, outstanding shares
of Common Stock; or

               (c)    any sale or conveyance of all or substantially all
of the property or business of the Company and the Company
Subsidiaries as an entirety;

then the Company, or such successor or purchasing corporation, as the case may
be, shall, as a condition precedent to such reclassification, change,
consolidation, merger, sale or conveyance, execute and deliver to the Trustee a
supplemental indenture in form satisfactory to the Trustee providing that the
holder of each Security then outstanding shall have the right to convert such
Security into the kind and amount of shares of stock and other securities and
property (including cash) receivable upon such reclassification, change,
consolidation, merger, sale or conveyance by a holder of the number of shares of
Common Stock deliverable upon conversion of such Security immediately prior to
such reclassification, change, consolidation, merger, sale or conveyance. Such
supplemental indenture shall provide for adjustments of the Conversion Price
which shall be as nearly equivalent as may be practicable to the adjustments of
the Conversion Price provided for in this Article X. If, in the case of any such
consolidation, merger, sale or conveyance, the stock or other securities and
property (including cash) receivable thereupon by a holder of Common Stock
includes shares of stock or other securities and property of a corporation other
than the successor or purchasing corporation, as the case may be, in such



                                       69
<PAGE>   76



consolidation, merger, sale or conveyance, then such supplemental indenture
shall also be executed by such other corporation and shall contain such
additional provisions to protect the interests of the holders of the Securities
as the Board of Directors of the Company shall reasonably consider necessary by
reason of the foregoing. The provisions of this Section 10.12 shall similarly
apply to successive consolidations, mergers, sales or conveyances.

               In the event the Company shall execute a supplemental indenture
pursuant to this Section 10.12, the Company shall promptly file with the Trustee
an Officers' Certificate briefly stating the reasons therefor, the kind or
amount of shares of stock or securities or property (including cash) receivable
by Holders of the Securities upon the conversion of their Securities after any
such reclassification, change, consolidation, merger, sale or conveyance and any
adjustment to be made with respect thereto. Neither the Trustee nor any
Conversion Agent shall have any duty whatsoever to determine whether a
supplemental indenture under this Section 10.12 is required or what the
provisions of such supplemental indenture should be, but may accept as
conclusive evidence of the correctiveness of such provisions, an Opinion of
Counsel with respect thereto, which the Company shall cause to be furnished to
the Trustee upon request.

               SECTION 10.13. COMPANY TO RESERVE COMMON STOCK. The Company shall
at all times reserve and keep available, free from preemptive rights, out of its
authorized and unissued Common Stock, solely for the purpose of effecting the
conversion of Securities, the full number of shares then issuable upon the
conversion in full of all Outstanding Securities.


                                   ARTICLE XI

                                  SUBORDINATION

               SECTION 11.01. SECURITIES SUBORDINATE TO SENIOR INDEBTEDNESS. The
Company covenants and agrees, and each Holder of a Security, by his acceptance
thereof, likewise covenants and agrees, that, to the extent and in the manner
hereinafter set forth in this Article, the indebtedness represented by the
Securities and the payment of the principal of, premium, if any, accrued
interest on, the Redemption Price or Purchase Price in respect of, each and all
of the Securities are hereby expressly made subordinate and subject in right of
payment to the prior payment in full of all Senior Indebtedness.

               SECTION 11.02.  PAYMENT OVER OF PROCEEDS UPON
DISSOLUTION, ETC. Upon any distribution of assets of the Company
in the event of




                                       70
<PAGE>   77


               (a) any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding,
relative to the Company or to its creditors, as such, or to its assets, or

               (b) any liquidation, dissolution or other winding up of the
Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or

               (c) any assignment for the benefit of creditors or any other
marshalling of assets and liabilities of the Company, or

               (d) any other event which would constitute an Event of Default
specified in Section 3.01(g) or Section 3.01(h).

then, and in any such event, the holders of Senior Indebtedness
shall be entitled to receive

                      (1)    payment in full of all amounts due or to
become due on or in respect of all Senior Indebtedness, or provision shall be
made for such payment, before the Holders of the Securities are entitled to
receive any payment (other than Permitted Junior Securities) on account of the
principal of, premium if any, accrued interest on, Redemption Price, Purchase
Price or cash in lieu of fractional shares on conversion or in respect of the
Securities, and

                      (2)    any payment or distribution of any kind or
character, whether in cash, property or securities (other than Permitted Junior
Securities), which may be payable or deliverable in respect of the Securities in
any such case, proceeding, dissolution, liquidation or other winding up or
event, including any such payment or distribution which may be payable or
deliverable by reason of the payment of any other indebtedness of the Company
being subordinated to the payment of the Securities.

               In the event that, notwithstanding the foregoing provisions of
this Section, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities (other than Permitted Junior
Securities), including any such payment or distribution which may be payable or
deliverable by reason of the payment of any other indebtedness of the Company
being subordinated to the payment of the Securities, before all Senior
Indebtedness is paid in full, or payment thereof provided for, and if prior to
the time of such payment or distribution, the Trustee or such Holder shall have
received written notice from the Company or a holder of Senior Indebtedness of
the occurrence of any such event and the fact that the Senior Indebtedness has
not been paid in full, then, in such event, such payment or distribution shall
be paid over or delivered forthwith to the trustee in bankruptcy, receiver,
liquidating trustee, Custodian, assignee, agent or other Person



                                       71

<PAGE>   78

making payment or distribution of assets of the Company for application to the
payment of all Senior Indebtedness remaining unpaid, to the extent necessary to
pay, or provide for the payment of, all Senior Indebtedness in full, after
giving effect to any concurrent payment or distribution to or for the holders of
Senior Indebtedness.

               The consolidation of the Company with, or the merger of the
Company into, another person or the liquidation or dissolution of the Company
following the conveyance or transfer of its properties and assets substantially
as an entirety to another person upon the terms and conditions set forth in
Article V shall not be deemed a dissolution, winding up, liquidation,
reorganization, assignment for the benefit of creditors or marshalling of assets
and liabilities of the Company for the purposes of this Section if the Person
formed by such consolidation or into which the Company is merged or the Person
which acquires by conveyance or transfer such assets substantially as an
entirety, as the case may be, shall as part of such consolidation, merger,
conveyance or transfer, comply with the conditions set forth in Article V.

               SECTION 11.03. DEFAULT ON SENIOR INDEBTEDNESS. The Company may
not make any payment of the principal of, premium, if any, accrued interest on,
or the Redemption Price or Purchase Price in respect of, the Securities, nor may
the Company acquire any Securities for cash or property (except as otherwise
provided by Article X and other than for capital stock of the Company) if:

                      (1) a payment default on any Senior Indebtedness has 
occurred and is continuing beyond any applicable grace period with respect
thereto; or

                      (2) a default (other than a default referred to
in the preceding clause (1)) on any Senior Indebtedness occurs and is continuing
that permits holders of such Senior Indebtedness to accelerate the maturity
thereof and the default is the subject of judicial proceedings or the Company
receives a notice of default thereof from any Person who may give such notice
pursuant to the instrument evidencing or document governing such Senior
Indebtedness (a "Senior Indebtedness Default Notice").

               If the Company receives a Senior Indebtedness Default Notice,
then a similar notice received within nine months thereafter relating to the
same default on the same issue of Senior Indebtedness shall not be effective for
purposes of this Section 11.03. The Company may resume payment on the Securities
and may acquire Securities if and when:

               (a) the default referred to above is cured or waived as provided
or permitted in accordance with the terms of the applicable Senior Indebtedness;
or








                                       72
<PAGE>   79


               (b) in the case of a default referred to in clause (2) of the
preceding paragraph, 179 or more days pass after the receipt by the Company of
the Senior Indebtedness Default Notice described in clause (2) above; and

this Indenture otherwise permits the payment or acquisition at
that time.

               In the event that, notwithstanding the foregoing, the Company
makes a payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and the Trustee, subject to Sections 11.09
and 11.11, or such Holder receives written notice from the Company or a holder
of Senior Indebtedness prior to the receipt of such payment that any such
payment is prohibited, then, and in such event, such payment shall (to the
extent permitted by law) be paid over and delivered forthwith to the Company by
or on behalf of the Person holding such payment for the benefit of the holders
of the Senior Indebtedness.

               Nothing contained in this Article XI or elsewhere in this
Indenture or in any of the Securities shall prevent the conversion by a Holder
of any Securities into shares of Common Stock in accordance with the provisions
for conversion of such Securities set forth in this Indenture, including the
payment of cash in lieu of fractional shares of Common Stock in accordance with
Article XI, or in any of such Securities in the event of an occurrence of the
events described in this Section 11.04.

               The provisions of this Section shall not apply to any payment
with respect to which Section 11.02 would be applicable.

               SECTION 11.04. PAYMENT PERMITTED IF NO DEFAULT. Nothing contained
in this Article XI or elsewhere in this Indenture or in any of the Securities
shall prevent the Company, at any time except during the pendency of any case,
proceeding, dissolution, liquidation or other winding up, assignment for the
benefit of creditors or other marshalling of assets and liabilities of the
Company referred to in Section 11.02 or under the conditions described in
Section 11.03, from making payments at any time of the principal of, premium, if
any, accrued interest on, or the Redemption Price or Purchase Price, as the case
may be, in respect of the Securities.

               SECTION 11.05. SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR
INDEBTEDNESS. Subject to payment in full of all Senior Indebtedness to the
extent and in the manner set forth in this Article XI, the Holders of the
Securities shall be subrogated to the extent of the payments or distributions
made to the holders of such Senior Indebtedness pursuant to the provisions of
this Article (equally and ratably with the holders of all indebtedness of the
Company which by its express terms is subordinated to


                                       73
<PAGE>   80


indebtedness of the Company to substantially the same extent as the Securities
are subordinated and is entitled to like rights of subrogation) to the rights of
the holders of such Senior Indebtedness to receive payments or distributions of
cash, property and securities applicable to the Senior Indebtedness until the
principal amount of, premium, if any, accrued interest on, or the Redemption
Price or Purchase Price, in respect of, the Securities shall be paid in full.
For purposes of such subrogation, no payments or distributions to the holders of
the Senior Indebtedness of any cash, property or securities to which the Holders
of the Securities or the Trustee would be entitled, except for the provisions of
this Article, and no payments over pursuant to the provisions of this Article to
the holders of Senior Indebtedness by Holders of the Securities or the Trustee,
shall as among the Company, its creditors other than holders of Senior
Indebtedness and the Holders of the Securities, be deemed to be a payment or
distribution by the Company to or on account of the Senior Indebtedness.

               SECTION 11.06. PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS. The
provisions of this Article are and are intended solely for the purpose of
defining the relative rights of the Holders of the Securities, on the one hand,
and the holders of Senior Indebtedness, on the other hand. Nothing contained in
this Article or elsewhere in this Indenture or in the Securities is intended to
or shall (a) impair, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders of the Securities, the obligation of the
Company, which is absolute and unconditional (and which, subject to the rights
under this Article of the holders of Senior Indebtedness, is intended to rank
equally with all other general obligations of the Company), to pay to the
Holders of the Securities the principal of, premium, if any, accrued interest
on, or the Redemption Price or Purchase Price in respect of the Securities, as
and when the same shall become due and payable in accordance with the terms of
the Securities and this Indenture; or (b) affect the relative rights against the
Company of the Holders of the Securities and creditors of the Company other than
the holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of
any Security from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, under this
Article of the holders of Senior Indebtedness to receive cash, property and
securities otherwise payable or deliverable to the Trustee or such Holder.

               SECTION 11.07. TRUSTEE TO EFFECTUATE SUBORDINATION. Each Holder
of a Security, by his acceptance thereof, authorizes and directs the Trustee on
his behalf to take such action as may be necessary or appropriate to effectuate
the subordination provided in this Article and appoints the Trustee his
attorney-in-fact for any and all such purposes.

<PAGE>   81

               SECTION 11.08.  NO WAIVER OF SUBORDINATION PROVISIONS.
No right of any present or future holder of any Senior Indebtedness to enforce
subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company or by any act
or failure to act by any such holder, or by any non-compliance by the Company
with the terms, provisions and covenants of this Indenture, regardless of any
knowledge thereof any such holder may have or be otherwise charged with.

               Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article or
the obligations hereunder of the Holders of the Securities to the holders of
Senior Indebtedness, do any one or more of the following: (i) change the manner,
place or terms of payment or extend the time of payment of, or renew, increase
or alter, Senior Indebtedness, or otherwise amend or supplement in any manner
Senior Indebtedness or any instrument evidencing the same or any agreement under
which Senior Indebtedness is outstanding; (ii) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (iii) release any Person liable in any manner for the collection
of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights
against the Company and any other Person.

               SECTION 11.09. NOTICE TO TRUSTEE. The Company shall give prompt
written notice to a Responsible Officer of the Trustee of any fact known to the
Company which would prohibit the making of any payment to or by the Trustee in
respect of the Securities. Notwithstanding the provisions of this Article or any
other provision of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts which would prohibit the making of any
payment to or by the Trustee in respect of the Securities, unless and until the
Trustee shall have received written notice thereof from the Company or a holder
of Senior Indebtedness or from any trustee therefor; and, prior to the receipt
of any such written notice, the Trustee shall be entitled in all respects to
assume that no such facts exist.

               The Trustee shall be entitled to rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness (or a trustee therefor) to establish that such notice has been
given by a holder of Senior Indebtedness (or a trustee therefor). In the event
that the Trustee determines in good faith that further evidence is required with
respect to the right of any Person as a holder of Senior Indebtedness to
participate in any payment or distribution



                                       75
<PAGE>   82


pursuant to this Article, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article, and if such evidence
is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

               SECTION 11.10. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF
LIQUIDATING AGENT. Upon any payment or distribution of assets of the Company
referred to in this Article, the Trustee and the Holders of the Securities shall
be entitled to rely upon any final, nonappealable order or decree entered by any
court of competent jurisdiction in which such insolvency, bankruptcy,
receivership, liquidation, reorganization, dissolution, winding up or similar
case or proceeding is pending, or a certificate of the trustee in bankruptcy,
liquidating trustee, Custodian, receiver, assignee for the benefit of creditors,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders of Securities, for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of
the Senior Indebtedness and other indebtedness of the Company, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article.

               SECTION 11.11. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR
INDEBTEDNESS. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness and shall not be liable to any such holders if it
shall in good faith mistakenly pay over or distribute to Holders of Securities
or to the Company or to any other Person cash, property or securities to which
any holders of Senior Indebtedness shall be entitled by virtue of this Article
or otherWise. The Trustee shall not be charged with knowledge of the existence
of Senior Indebtedness or of any facts that would prohibit any payment hereunder
or that would permit the resumption of any such payment unless a Responsible
Officer of the Trustee shall have received notice to that effect at the address
of the Trustee set forth in Section 11.06. With respect to the holders of Senior
Indebtedness, the Trustee undertakes to perform or to observe only such of its
covenants or obligations as are specifically set forth in this Article XI and no
implied covenants or obligations with respect to holders of Senior Indebtedness
shall be read into this Indenture against the Trustee.

               SECTION 11.12. RIGHTS OF TRUSTEE AS HOLDER OF SENIOR
INDEBTEDNESS; PRESERVATION OF TRUSTEE'S RIGHTS. The Trustee in its individual
capacity shall be entitled to all the rights set forth in this Article with
respect to any Senior Indebtedness which may at any time be held by it, to the
same extent as any other holder of Senior Indebtedness, and nothing in this
Indenture shall deprive the Trustee of any of its rights as such holder. Nothing
in this Article shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 4.07.

               SECTION 11.13. ARTICLE X APPLICABLE TO PAYING AGENTS. In case at
any time any Paying Agent other than the Trustee shall have been appointed by
the Company and be then acting hereunder, the term "Trustee" as used in this
Article shall in such case (unless the context otherwise requires) be construed
as extending to and including such Paying Agent within its meaning as fully for
all intents and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee; provided, however, that Sections 11.09
and 11.11 shall not apply to the Company or any Affiliate of the Company if it
or such Affiliate acts as Paying Agent.


                                   ARTICLE XII

                         REPURCHASE ON CHANGE IN CONTROL

               SECTION 12.01. RIGHT TO REQUIRE REPURCHASE. In the event that a
Change in Control shall occur, then each Holder of Securities shall have the
right (the "Repurchase Right"), at such Holder's option, to require the Company
to repurchase, and upon the exercise of such Repurchase Right the Company shall
purchase, all of such Holder's Securities on the date (the "Purchase Date") that
is 45 days after the date of the Company Notice at a purchase price equal to
100% of the principal amount of the Securities to be repurchased plus accrued
and unpaid interest to the Purchase Date (the "Purchase Price"); provided,
however, that installments of interest on Securities whose Stated Maturity is on
or prior to the Purchase Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such on the
relevant Record Date according to their terms and the provisions of Section
2.07. Whenever in this Indenture there is a reference, in any context, to the
principal of any Security as of any time, such reference shall be deemed to
include reference to the Purchase Price payable in respect of such Security to
the extent that such Purchase Price is, was or would be so payable at such time,
and express reference to the Purchase Price in any provision of this Indenture
shall not be construed as excluding the Purchase Price in those provisions of
this Indenture where such express reference is not made.

<PAGE>   84

               SECTION 12.02. NOTICES; METHOD OF EXERCISING PURCHASE RIGHT, ETC.
(a) On or before the 30th day after the occurrence of a Change in Control, the
Company or, at the request and expense of the Company, the Trustee, shall give
to all Holders of Securities, in the manner provided in Section 1.06, notice
(the "Company Notice") of the occurrence of a Change in Control and of the
Repurchase Right set forth herein arising as a result thereof. The Company
shall, so long as the Debentures are listed on the Luxembourg Stock Exchange,
and the rules of such Stock Exchange so require, cause the Company Notice to be
published in an Authorized Newspaper in Luxembourg, and also deliver a copy of
such notice of a repurchase right to the Trustee.

               Each Company Notice shall include a form of change in control
purchase notice ("Change in Control Purchase Notice") to be completed by each
Holder and shall state:

               (i) the Purchase Date;

               (ii) the date by which the Repurchase Right must be exercised
("Repurchase Expiry Date");

               (iii) the Purchase Price;

               (iv) a description of the procedure which a Holder must follow to
exercise a Repurchase Right and the place or places where such Securities are to
be surrendered for payment of the Purchase Price;

               (v) that on the Purchase Date the Purchase Price will become due
and payable upon each such Security designated by the Holder to be repurchased,
and that interest thereon shall cease to accrue on and after the Repurchase
Expiry Date; and

               (vi) the Conversion Price then in effect, that at the close of
business on the Repurchase Expiry Date, the right to convert the principal
amount of the Securities to be repurchased will terminate, and the place or
places where such Securities may be surrendered for conversion.

               No failure of the Company to give the foregoing notices or defect
therein shall limit any Holder's right to exercise a Purchase Right or affect
the validity of the proceedings for the repurchase of Securities.

               If any of the foregoing provisions or other provisions of this
Article are inconsistent with applicable law, such law shall govern.

               (b) To exercise a Repurchase Right, a Holder of Securities shall
deliver, in accordance with the procedure set



                                       78
<PAGE>   85


forth in the Company Notice, on or before the 45th day after the date of the
Company Notice:

               (i) Change in Control Purchase Notice, which Notice shall set
forth:

                      (A) the name of the Holder;

                      (B) the principal amount of the Securities to be
repurchased; and

                      (C) a statement that an election to exercise the
Repurchase Right is being made thereby; and

               (ii) the Securities with respect to which the Repurchase Right is
being exercised, which shall be all of such Holder's Securities or any portion
thereof which is an authorized denomination of such Securities. Such Change in
Control Notice shall be irrevocable, except that the right of the Holder to
convert the Securities with respect to which the Repurchase Right is being
exercised shall continue until the close of business on the Purchase Date.

               (c) In the event a Repurchase Right shall be exercised in
accordance with the terms hereof, the Company shall pay or cause to be paid to
the Trustee or any Paying Agent the Purchase Price in cash for payment to the
Holder on the Purchase Date provided, however, that installments of interest
that mature on or prior to the Purchase Date shall be payable in cash to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of business on the relevant Regular Record Date according to
the terms and provisions of Article II.

               (d) If any Security (or portion thereof) surrendered for
repurchase shall not be so paid on the Purchase Date, the principal amount of
such Security (or portion thereof, as the case may be) shall, until paid, bear
interest from the Purchase Date at the rate borne by such Security, and each
Security shall remain convertible into Common Stock until the principal,
together with any accrued and unpaid interest thereon, of such Security (or
portion thereof, as the case may be) shall have been paid or duly provided for.


                                  ARTICLE XIII

                    SATISFACTION AND DISCHARGE OF INDENTURE;

                      (ii)  all such Securities not theretofore
delivered to the Trustee or the Paying Agent or its agent for cancellation
(other than Securities referred to in Section 13.01(a)(1) and (2) above):

                             (1) have become due and payable; or

                             (2)  have been called for redemption pursuant

Securities not theretofore delivered to the Trustee for cancellation, including
principal, premium, if any, and interest due or to become due to the Maturity
Date, Redemption Date or Purchase Date, as the case may be;

Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent herein provided for relating to the satisfaction and
discharge of this Indenture have been complied with.

               (b) all obligations of the Company in respect of the Securities
shall cease and be discharged, and the Holders of such Securities shall
thereafter be restricted exclusively to such funds for any and all claims of
whatsoever nature on their part under this Indenture or with respect to such

follows: on each January 31 and July 31 (each, a "Principal Payment Date"),
commencing on January 31, 2004, with the last principal installment being due on
July 31, 2005, the Company will cause to be paid to the Holder of record of this
Security as of the close of business on the Principal Payment Record Date
immediately preceding such Principal Payment Date, a sum in cash equal to 25% of
the aggregate principal amount of this Debenture outstanding on such Principal
Payment Date, except that the last such installment shall be equal to the
aggregate principal amount of the Debenture outstanding on July 31, 2005
(together with accrued interest thereon to such Principal Payment Date); and to
pay interest on the principal amount of this Security outstanding from time to
time from the Initial Closing Date or from the most recent Interest Payment Date
(as defined below) to which interest has been paid or duly provided for,
semiannually in arrears on January 31 and July 31 in each year (each, an
"Interest Payment Date"), commencing January 31, 1999, at the rate of 6% per
annum, until the principal hereof is due, and at the rate of 10% per annum on
any overdue principal and, to the extent permitted by law, on any overdue
interest until paid in full. The interest so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, as provided in the
Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest, which shall be the January 15 or July 15 (whether
or not a Business Day) next preceding such Interest Payment Date.

               As provided in the Indenture, on each Interest Payment Date
during the PIK Payment Period, interest then due shall be paid by the issuance
of PIK Debentures in an aggregate principal amount equal to the amount of cash
interest that would otherwise be paid on such Interest Payment Date, together
with a cash payment in lieu of any Fractional Principal Amount equal to, at the
Company's option, either (a) the Holder's proportionate interest in the net
proceeds from the sale or sales in the open market of the aggregate of the
Fractional Principal Amounts or (b) the amount of the Holder's Fractional
Principal Amount. Except as otherwise provided in the Indenture, any accrued
interest payable on an Interest Payment Date not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such Regular
Record Date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on



                                       2

a Special Record Date for the payment of such Defaulted Interest to be fixed by
the Company, notice whereof shall be given to Holders of Securities not less
than 10 days prior to such Special Record Date, or be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in the Indenture. Payments
of principal shall be made upon the surrender of this Security at the option of
the Holder at the office of the Paying Agent in Luxembourg, or at such other
office or agency of the Company as may be designated by it for such purpose in
the State of New York or Western Europe, in such coin or currency of The United
States of America as at the time of payment shall be legal tender for the
payment of public and private debts. Payment of interest on this Security may be
made by United States Dollar check drawn on a bank in the Borough of Manhattan,
The City of New York, mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register, or, upon written application
by the Holder to the Registrar setting forth wire instructions not later than
the relevant Record Date, if any, by wire transfer to a United States Dollar
account maintained by the Holder with a bank in the Borough of Manhattan, The
City of New York (provided that such Holder shall have furnished wire
instructions in writing to any Paying Agent no later than 15 days prior to the
relevant payment date).

               Each Holder of this Global Security, by acceptance hereof, agrees
that transfers of beneficial interests herein may be effected only through a
book entry system maintained by Euroclear or Cedel, and that ownership of a
beneficial interest in this Global Security shall be required to be reflected in
a book entry.

               1. The Company will pay to the Holder of this Security who is a
United States Alien (as defined below) such additional amounts ("Additional
Amounts") as may be necessary in order that every net payment of the principal
of, premium, if any, and interest on this Security (including payment on
redemption or repurchase), and any cash payments made in lieu of issuing
fractional Conversion Shares upon conversion of this Security, after deduction
or withholding for or on account of any present or future tax, assessment or
governmental charge imposed upon or as a result of such payment by the United
States or any political subdivision or taxing authority thereof or therein, will
not be less than the amount provided for in this Security to be then due and
payable; provided, however, that the foregoing obligation to pay Additional
Amounts will not apply to any one or more of the following:

                  (a) any tax, assessment or other governmental charge which 
would not have been so imposed but for (i) the existence of any present or
former connection between such Holder



                                       3
<PAGE>   93

or the beneficial owner (or between a fiduciary, settlor, beneficiary, member,
stockholder of or possessor of a power over such Holder, if such Holder is an
estate, a trust, a partnership or a corporation) and the United States or any
political subdivision or taxing authority thereof or therein, including, without
limitation, such Holder or beneficial owner (or such fiduciary, settlor,
beneficiary, member, stockholder or possessor) being or having been a citizen or

having been engaged in trade or business therein or being or having been present
therein, or having or having had an office, fixed place of business or permanent
establishment therein, (ii) such Holder's or beneficial owner's present or

United States tax purposes, or a corporation which accumulates earnings to avoid
United States federal income tax, (iii) such Holder or beneficial owner (or such
fiduciary, settlor, beneficiary, member, stockholder or possessor) is considered
as having made an election, the effect of which is to make payments of principal
of, premium, if any, and interest on this Security subject to United States
federal income tax; provided, however, if failure to make such election, would
result in a higher income tax liability related to this Security then such
Holder shall be deemed not to have made such election or (iv) such Holder's
status as a bank extending credit pursuant to a loan agreement entered into in
the ordinary course of business;

               (b) any tax, assessment or other governmental charge which would
not have been so imposed but for the presentation by the Holder of this Security
for payment on a date more than 10 days after the date on which such payment
became due and payable or the date on which payment thereof is duly provided,
whichever occurs later;

               (c) any estate, inheritance, gift, sales, transfer or personal or
intangible property or any similar tax, assessment or governmental charge;

               (d) any tax, assessment or other governmental charge which would
not have been imposed but for the failure to comply with any certification,
information, documentation or other reporting requirements concerning the
nationality, residence, identity or present or former connection with the United
States of the Holder or beneficial owner of this Security, if such compliance is
required by statute, regulation or ruling or other administrative action of the
United States or any political subdivision or taxing authority thereof or
therein as a precondition to relief or exemption from such tax, assessment or
other governmental charge;

               (e) any tax, assessment or other governmental charge which is
payable otherwise than by deduction or withholding from payments of principal
of, premium, if any, or interest on this Security;

               (f) any tax, assessment or other governmental charge imposed on
interest received by a Person holding, actually or constructively, 10% or more
of the total combined voting power of all classes of capital stock of the
Company entitled to vote;

               (g) any tax, assessment or other governmental charge required to
be withheld by any Paying Agent from any payment of the principal of, premium,
if any, or interest on this Security, if such payment can be made without such
withholding by any other Paying Agent;

               (h) any tax, assessment or other governmental charge imposed on a
Holder that is not a beneficial owner of this Security or that is a partnership
or a fiduciary, but only to the extent that any beneficial owner or beneficiary
or settlor with respect to the fiduciary or member of the partnership would not
have been entitled to the payment of Additional Amounts had the beneficial
owner, beneficiary, settlor or member directly received its beneficial or
distributive share of payments on this Security; and

               (i) any combination of items (a), (b), (c), (d), (e), (f), (g)
and (h) above.

               2. For purposes of this Security, "United States" means the

States Alien" means any Person that is, for United States federal income tax
purposes, (a) a foreign corporation; (b) a nonresident alien individual; (c) an
estate, the income of which is not subject to United States federal income
taxation (regardless of its source) or a trust, if a United States court is able
to exercise primary supervision over its administration and one or more United
States persons have the authority to control all substantial decisions of such
trust; (d) a "foreign trust" as defined in Section 7701(a)(31) of the Code; or
(e) a foreign partnership, one or more of the members of which is, for United

assessment or other governmental charge imposed by any government or any
political subdivision or taxing authority thereof or therein. Whenever in this
Security there is

                                [FORM OF REVERSE]


               1. This Security is one of a duly authorized issue of securities
of the Company designated as its 6% Convertible Subordinated Debentures due 2005
(herein called the "Securities"), limited in aggregate principal amount to
$47,762,092 (including PIK Debentures), issued and to be issued under an
Indenture, dated July 23, 1998 (herein called the "Indenture"), between the
Company and American Stock Transfer and Trust, as Trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the holders of Senior Indebtedness, and
the Holders of the Securities and of the terms upon which the Securities are,
and are to be, authenticated and delivered. The Securities are issuable in
registered form, without coupons, in denominations of $1,000 and integral
multiples of $1,000. A Holder may transfer or exchange Securities in accordance
with the Indenture. The Registrar or Transfer Agent may require a Holder, among
other things, to furnish appropriate endorsements or transfer documents or
certificates and to pay any taxes and fees required by law or permitted by the
Indenture.

               2. Prior to January 31, 2000, this Security will not be
redeemable at the option of the Company. On and after that date and prior to
Maturity, the Company may redeem this Security for cash in whole or in part (in
any integral multiple of $1,000), upon not less than 30 nor more than 60 days'
notice to the Holders of the Securities prior to the Redemption Date, at the
Redemption Prices of the Securities, expressed as a percentage of the principal
amount of the Securities to be redeemed, as set forth in the following table,
during each 12- month period beginning on the date specified in such table, in
each case plus accrued and unpaid interest to the Redemption Date (subject to
the right of Holders of record on the relevant Record Date to receive interest
due on an Interest Payment Date).

               In case of a redemption of the Securities in part,
selection of the Securities for redemption will be made by the




                                        1

<PAGE>   97


Trustee, on a pro rata basis, by lot or such other method as the Trustee shall
deem fair and appropriate.

               3. If as a result of any change in, or amendment to, the laws
(including any regulations or rulings promulgated thereunder) of the United
States or any political subdivision or taxing authority thereof or therein
affecting taxation, or any change in, or amendment to, the application or
official interpretation of such laws, regulations or rulings (collectively, a
"Tax Law Change"), the Company has or will become obligated to pay to the Holder
of any Security Additional Amounts (as described in Paragraph 1 on the face of
this Security) and such obligation cannot be avoided by the Company taking
reasonable measures available to it, then the Company may, at its option, redeem
the Securities in whole, but not in part, upon not less than 30 nor more than 90
days' notice to the Holders prior to the earliest date on which the Company
would be obligated to pay any such Additional Amounts were a payment in respect
of the Securities then due, provided that at the time such notice of redemption
is given, such obligation to pay such Additional Amounts remains in effect. Any
redemption of Securities pursuant to this Paragraph 3 shall be made at a
Redemption Price equal to 100% of the principal amount plus accrued and unpaid
interest to the Redemption Date and any Additional Amounts then payable. Prior
to the giving of any notice of redemption pursuant to this Paragraph, the
Company shall deliver to the Trustee (a) an Officers' Certificate stating that
the Company is entitled to effect such redemption and setting forth a statement
of facts showing that the conditions precedent to the right of the Company so to
redeem have occurred and (b) an Opinion of Counsel to the effect that the legal
conditions precedent to the right of the Company to effect such redemption have
occurred. In the case of the occurrence of a Tax Law Change, the Company's right
to redeem the Securities shall continue as long as the Company is obligated to
pay such Additional Amounts, notwithstanding that the Company shall have made
payments of Additional Amounts specified in such second paragraph.

               4. In the event of a redemption of less than all of the
Securities, the Company will not be required (a) to register the transfer or
exchange of Securities for a period of 15 days immediately preceding the date
notice is given identifying the serial numbers of the Securities called for such
redemption, or (b) to register the transfer or exchange of any Security, or
portion thereof, called for redemption.

               5. Securities shall be transferred to all beneficial owners in
exchange for their beneficial interests in a Global Security if (A) the
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for such Global Security, and a successor depositary is not appointed
by the



                                       2
<PAGE>   98


Company within 90 days of such notice, or (B) an Event of Default has occurred
and is continuing.

               6. In any case where the Stated Maturity for the payment of the
principal of, premium, if any, or interest, including Additional Amounts, on any
Security or the last day on which a Holder of a Security has a right to convert
his Security shall be, at any Place of Payment or Place of Conversion, as the
case may be, a day on which banking institutions at such Place of Payment or
Place of Conversion are authorized or obligated by law or executive order to
close, then payment of principal, premium, if any, or interest, including
Additional Amounts, or delivery for conversion of such Security need not be made
on or by such date at such place but may be made on or by the next succeeding
day at such place which is not a day on which banking institutions are
authorized or obligated by law or executive order to close, with the same force
and effect as if made on the date for such payment or the date fixed for
redemption, or by such last day for conversion, and no interest shall accrue on
the amount so payable for the period after such date.

               7. Subject to and upon compliance with the provisions of the
Indenture, the Holder of this Security is entitled, at its option, at any time
on and after November 30, 1998, and on or before the close of business on July
31, 2005 (the Stated Maturity of the principal amount of this Security), or in
case this Security or a portion hereof is called for redemption or the Holder
hereof has exercised his right to require the Company to repurchase this
Security or a portion thereof, then, in respect of this Security until and
including, but (unless the Company defaults in making the payment due upon
redemption or repurchase, as the case may be) not after, the close of business
on the Redemption Date or the Purchase Date, as the case may be, to convert this
Security (or any portion of the amount hereof that is an integral multiple of
$1,000) into fully paid and nonassessable shares of Common Stock of the Company
("Conversion Shares") at an initial Conversion Price of $14.3125 for each
Conversion Share (or at the then current adjusted Conversion Price, if an
adjustment has been made as provided in the Indenture) by surrender of this
Security, duly endorsed or assigned to the Company or in blank and, in case such
surrender shall be made during the period from the close of business of any
Regular Record Date next preceding any Interest Payment Date to the opening of
business on such Interest Payment Date ("Interest Period"), also accompanied by
payment in United States currency of an amount equal to the interest payable on
such Interest Payment Date on the principal amount of this Security then being
converted, and also a conversion notice duly executed, to the Company at Banque
International a Luxembourg S.A. in Luxembourg, or at such other office or agency
of the Company as may be designated by it for such purpose in the State of New
York or Western Europe (each a "Conversion Agent"); except that if this Security
or any portion hereof has been called for redemption




                                        3

<PAGE>   99

and, pursuant to Section 10.01 of the Indenture, as a result of such redemption
the right to convert this Security or such portion terminates after the Regular
Record Date preceding any Interest Payment Date and on or before such Interest
Payment Date, then, notwithstanding such conversion, the interest payable on
such Interest Payment Date will be paid to the registered Holder of this
Security on such Regular Record Date. In such event, this Security, when
surrendered for conversion, shall be accompanied by payment in United States
currency of an amount equal to the difference between (i) the interest on the
principal amount of this Security or such portion hereof payable on such
Interest Payment Date and (ii) the amount of accrued interest on the principal
amount of this Security or portion hereof to but not including the date of
conversion. Subject to the aforesaid requirement for payment and, in the case of
a conversion after the Regular Record Date preceding any Interest Payment Date
and on or before such Interest Payment Date, to the right of the Holder of this
Security (or any Predecessor Security) of record at such Regular Record Date to
receive an installment of interest (with certain exceptions provided in the
Indenture), payment shall be made on conversion, for interest accrued hereon
from the Interest Payment Date preceding the date of conversion to the
Conversion Date. No payment or adjustment is to be made for dividends on the
Common Stock issued on conversion hereof. The Company shall thereafter deliver
to the Holder the fixed number of Conversion Shares of Common Stock (together
with any cash adjustment, as provided in the Indenture) into which this Security
is convertible and such delivery will be deemed to satisfy the Company's
obligation to pay the principal amount of this Security.

               No fractions of shares or scrip representing fractions of shares
will be issued on conversion, but instead of any fractional interest (calculated
to the nearest 1/100th of a share) the Company shall pay a cash adjustment as
provided in the Indenture. The Conversion Price is subject to adjustment as
provided in the Indenture. In addition, the Indenture provides that in case of
certain consolidations or mergers to which the Company is a party or the
transfer of all or substantially all of the property and assets of the Company,
the Indenture shall be amended, without the consent of any Holders of
Securities, so that this Security, if then Outstanding, will be convertible
thereafter, during the period this Security shall be convertible as specified
above, only into the kind and amount of securities, cash and other property
receivable upon such consolidation, merger or transfer by a holder of the number
of shares of Common Stock of the Company into which this Security could have
been converted immediately prior to such consolidation, merger or transfer.

               8. If a Change in Control occurs, the Holder of this Security
shall have the right, in accordance with the provisions of the Indenture, to
require the Company to repurchase all or a





                                       4
<PAGE>   100


portion of such Holder's Securities specified in a Change in Control Purchase
Notice for cash at a Purchase Price equal to 100% of the principal amount
thereof plus accrued and unpaid interest to the Purchase Date, provided that any
portion of this Security to be repurchased is an authorized denomination.
Whenever in this Security there is a reference, in any context, to the principal
of any Security as of any time, such reference shall be deemed to include
reference to the Purchase Price payable in respect of such Security to the
extent that such Purchase Price is, was or would be so payable at such time, and
express reference of the Purchase Price in any provision of this Security shall
not be construed as excluding the Purchase Price in those provisions of this
Security when such express reference is not made.

               Within 30 days after the occurrence of a Change in Control, the
Company is obligated to give to all Holders of record of the Securities notice,
as provided in the Indenture (the "Company Notice"), of the occurrence of such
Change in Control and of the Repurchase Right arising as a result thereof. The
Company must also deliver a copy of the Company Notice to the Trustee. To
exercise the purchase right, a Holder of such Securities must deliver to the
Company (or an agent designated by the Company for such purpose), the Trustee
and any Paying Agent (including such agent in Luxembourg) on or before the 45th
day after the date of the Company Notice, a Change in Control Purchase Notice,
together with the Securities with respect to which the right is being exercised,
which Securities may be delivered to the Company's designated agent for such
purpose, or if no such agent has been appointed, to the Trustee or to the Paying
Agent in Luxembourg.

               Under the Indenture, a "Change in Control" of the Company is
deemed to have occurred at such time as (i) any person (as the term "person" is
used in Section 13(d)(3) or Section 14(d)(2) of the Exchange Act), other than
the Company, any Company Subsidiary, Robert J. Skandalaris or any employee
benefit plan of either the Company or any Company Subsidiary, files a Schedule
13D or 14D-1 under the Exchange Act (or any successor schedule, form or report)
disclosing that such person has become the beneficial owner of 50% or more of
the total voting power in the aggregate of all classes of capital stock of the
Company then outstanding normally entitled to vote in elections of directors,
with certain exceptions, or (ii) there shall be consummated any consolidation or
merger of the Company (a) in which the Company is not the continuing or
surviving corporation (other than any consolidation or merger effected primarily
to change the jurisdiction of incorporation of the Company) or (b) pursuant to
which the Common Stock would be converted into cash, securities or other
property, in each case, other than a consolidation or merger of the Company in
which the holders of Common Stock immediately prior to the consolidation or
merger have, directly or indirectly, at least a majority of the total voting
power in

the aggregate of all classes of capital stock of the continuing or surviving
corporation normally entitled to vote in elections of directors immediately
after the consolidation or merger. The Indenture does not permit the Board of
Directors to waive the Company's obligation to purchase Securities at the option
of a Holder in the event of a Change in Control of the Company.

               The Company will comply with the provisions of Rule 13e-4, Rule
14e-1 and any other tender offer rules under the Exchange Act which may then be
applicable, and will file Schedule 13E-4 or any other schedule required
thereunder in connection with any offer by the Company to purchase Securities at
the option of the Holders thereof upon a Change in Control.

               9. In the event of redemption, repurchase or conversion of this
Security in part only, a new Security or Securities for the unredeemed,
unrepurchased or unconverted portion hereof will be issued in the name of the
Holder hereof.

               10. Each Holder of this Security, by acceptance hereof,
acknowledges and agrees to the provisions of the Registration Rights Agreement
among the Company and the Placement Agents (the "Registration Rights
Agreement"), including, without limitation, the obligations of the Company to
pay interest on this Security at the increased rates specified therein upon the
occurrence of certain defaults by the Company in complying with certain
covenants contained in the Registration Rights Agreement and the obligations of
the Holders with respect to a "Shelf Registration Statement" and the
indemnification of the Company to the extent provided in the Registration Rights
Agreement.

               The following is a summary of the interest rate increase
provisions of the Registration Rights Agreement, which summary does not purport
to be complete and is subject to, and qualified in its entirety by reference to
the detailed provisions of the Registration Rights Agreement.

               The Company agrees, under the Registration Rights Agreement and
subject thereto, for the benefit of the Holders of the Securities and their
successors and transferees that (i) it will, at its cost, file a Shelf
Registration Statement with the Commission with respect to resales of Conversion
Shares by November 30, 1998, (ii) it will use its best efforts to have such
Shelf Registration Statement declared effective by the Commission by January 31,
1999, and (iii) it will use its best efforts to maintain such Shelf Registration
Statement continuously effective under the Securities Act to permit the
prospectus included the Shelf Registration Statement to be used by a holder of
Conversion Shares for a period of two years from the Final Closing Date or a
shorter period, which shorter period will terminate when all of the Conversion
Shares have been sold pursuant to the Shelf Registration Statement or Rule 144
under the Securities Act (the "Shelf Registration Period"), provided that the
Company may




                                        6

<PAGE>   102

suspend the use of the Shelf Registration Statement for a period not to exceed
45 days in any 12 month period (during the Shelf Registration Period) for valid
business reasons, including acquisitions and divestitures of assets, filings
with the Commission, pending corporate developments and similar reasons.

               If the Company defaults in complying with clause (i) above then,
at such time, the interest rate on the Securities (the "Initial Rate") will
increase by 25 basis points. Such increase will remain in effect until the date
on which such Shelf Registration Statement is filed, on which date the interest
rate on the Securities will revert to the Initial Rate (plus any increases in
the Initial Rate pursuant to the following sentence). If the Shelf Registration
Statement is not declared effective as provided in clause (ii) above, then, at
such time, and on each successive 30th day following such time, the interest
rate on the Securities (which interest rate will be the sum of the Initial Rate
plus any increase in such interest rate pursuant to a default in complying with
clause (i) above plus any increases pursuant to this sentence) will increase by
an additional 25 basis points; provided, however, that the Initial Rate will not
increase by more than 75 basis points pursuant to this sentence and will not
increase by more than 100 basis points pursuant to this sentence and a default
in complying with clause (i) above. Such increase or increases will remain in
effect until the date on which the Shelf Registration Statement is declared
effective, on which date the interest rate on the Securities will revert to the
Initial Rate. If the Company fails to keep the Shelf Registration continuously
effective or useable for the period specified in clause (iii) above, then at
such time as the Shelf Registration Statement is no longer effective or useable,
and on each successive 30th day following such time, and until the earliest of
(a) the date that the Shelf Registration Statement is again deemed effective,
(b) the date that is the second anniversary of the Final Closing Date (or, in
the event that Rule 144(k) under the Securities Act is amended to provide for a
shorter holding period, until the end of such shorter holding period), and (c)
the date as of which all the Conversion Shares have been sold pursuant to the
Shelf Registration Statement or Rule 144, the interest rate on the Securities
will increase by 25 basis points; provided that the interest rate on the
Securities will not increase by more than 100 basis points pursuant to a default
in compliance with clause (ii) above and this sentence. Such increase or
increases will remain effective until the Shelf Registration Statement is again
effective and useable in accordance with clause (iii) above, on which date, the
interest rate on the Securities will revert to the Initial Rate. Notwithstanding
anything to the contrary in the Registration Rights Agreement, a default in
compliance with clause (iii) above will not be deemed to have occurred and be
continuing by reason of a suspension in use of the Shelf Registration Statement
for valid business reasons to the extent set forth above.

               11. The indebtedness evidenced by this Security is, to the extent
and in the manner provided in the Indenture, subordinate and subject in right of
payment to the prior payment in full of all Senior Indebtedness of the Company,
and this Security is issued subject to such provisions of the Indenture with
respect thereto. Each Holder of this Security, by accepting the same, (a) agrees
to and shall be bound by such provisions, (b) authorizes and directs the Trustee
on his behalf to take such action as may be necessary or appropriate to
effectuate the subordination so provided and (c) appoints the Trustee his or its
attorney-in-fact for any and all such purposes.

               12. If an Event of Default shall occur and be continuing, the
principal of all the Securities, together with accrued interest to the date of
declaration, may be declared due and payable in the manner and with the effect
provided in the Indenture. Upon indefeasible payment in full in cash (i) of the
amount of principal so declared due and payable, together with accrued interest
to the date of declaration, and (ii) of interest on any overdue principal and
overdue interest, all of the Company's obligations in respect of the payment of
the principal of and interest on the Securities shall terminate.

               13. The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities under
the Indenture at any time by the Company and the Trustee with the written
consent of the Holders of a majority in principal amount of the Securities at
the time outstanding. The Indenture also contains provisions permitting the
Holders of a majority in principal amount of the Securities at the time
outstanding, on behalf of the Holders of all the Securities, to waive compliance
by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver
by the Holder of this Security shall be conclusive and binding upon such Holder
and upon all future Holders of this Security and of any Security issued in
exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Security or such other Security. Subject to certain
exceptions set forth in the Indenture, without the consent of any Holder, the
Company and the Trustee may amend the Indenture or the Securities to evidence
the succession of another Person to the Company and the assumption by such
successor to the covenants and obligations of the Company in the Indenture or
this Security, to cure any ambiguity, omission, defect or inconsistency, to add
guarantees or secure the Securities, to add to the covenants of the Company for
the benefit of Holders or to surrender any right or power conferred upon the
Company, to make provision with respect to conversion rights of Holders in
accordance with Section 10.12 of the Indenture, or to make certain changes in
the subordination provisions.

               14. No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of, premium,
if any, and interest on (including Additional Amounts, as described on the face
hereof) this Security at the times, places and rate, and in the currency herein
prescribed or to convert this Security as provided in the Indenture.

               15. As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of Securities is registrable on the
Security Register upon surrender of a Security for registration of transfer (a)
at the Corporate Trust Office of the Trustee or at such other office or agency
of the Company as may be designated by it for such purpose in the State of New
York, or (b) subject to any laws or regulations applicable thereto and to the
right of the Company to terminate the appointment of any Transfer Agent, at the
office of Banque Internationale a Luxembourg S.A. as the Company's Transfer
Agent in Luxembourg or at such other offices or agencies as the Company may
designate, duly endorsed by, or accompanied by a written instrument of transfer
in form satisfactory to the Company and the Registrar duly executed by, the
Holder thereof or his attorney duly authorized in writing, and thereupon one or
more new Securities, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees by
the Registrar. No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
recover any tax or other governmental charge payable in connection therewith.

               16. Securities in certificated form may be presented for transfer
(with the form of transfer endorsed thereon duly executed), at the offices of
any Transfer Agent or at the office of the Registrar, without service charge but
upon payment of any taxes and other governmental charges as provided in the
Indenture. The Trustee has initially been appointed as the Company's principal
Transfer Agent and Banque Internationale a Luxembourg S.A. in Luxembourg has
initially been appointed as the Company's Luxembourg Transfer Agent. Any
registration of transfer or exchange will be effected upon the Transfer Agent or
the Registrar, as the case may be, being satisfied with the documents of title
and identity of the person making the request and, upon registration of such
transfer in the Security Register, and subject to such reasonable regulations as
the Issuer may from time to time agree upon with the Transfer Agents and the
Registrar, all as described in the Indenture. Securities may be transferred in
whole or in part in the principal amount of $1,000 or an integral multiple of
$1,000. In the case of a partial transfer of Debentures, new Securities may be
obtained from the Transfer Agents as described in the Indenture.

               17. Prior to due presentation of a Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Security is registered, as the owner
thereof for all purposes, whether or not such Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

               18. THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, UNITED STATES OF
AMERICA, WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS.

received, hereby promises to pay to _______________ or registered assigns, the
principal sum of U.S. $___________ in installments as follows: on each January
31 and July 31 (each, a "Principal Payment Date") commencing on January 31,
2004, and with the final principal installment being due on July 31, 2005, the
Company will cause to be paid to the Holder of record of this Security as of the
close of business on the Principal Payment Record Date immediately preceding
such Principal Payment Date, a sum in cash equal to 25% of the aggregate
principal amount of this Debenture outstanding on such Principal Payment Date,
except that the last such installment shall be equal to the aggregate principal
amount of this Debenture outstanding on July 31, 2005 (together with accrued
interest thereon to such Principal Payment Date); and to pay interest on the
principal amount of this Security outstanding from time to time from the Initial
Closing Date or from the most recent Interest Payment Date (as defined below) to
which interest has been paid or duly provided for, semiannually in arrears on
January 31 and July 31 in each year (each, an "Interest Payment Date"),
commencing January 15, 1999, at the rate of 6% per annum, until the principal
hereof is due, and at the rate of 10% per annum on any overdue principal and, to
the extent permitted by law, on any overdue interest until paid in full. The
interest so payable, and punctually paid or duly provided for, on any Interest
Payment Date will, as provided in the Indenture, be paid to the Person in whose
name this Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest, which shall be
the January 15 or July 15 (whether or not a Business Day) next preceding such
Interest Payment Date.

               As provided in the Indenture, on each Interest Payment Date
during the PIK Payment Period, interest then due shall be paid by the issuance
of PIK Debentures in an aggregate principal amount equal to the amount of cash
interest that would otherwise be paid on such Interest Payment Date, together

Company's option, either (a) the Holder's proportionate interest in the net
proceeds from the sale or sales in the open market of the aggregate of the
Fractional Principal Amounts or (b) the amount of the Holder's Fractional
Principal Amount. Except as otherwise provided in the Indenture, any accrued
interest payable on an Interest Payment Date not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such Regular
Record Date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Company, notice whereof shall be given to Holders of Securities not less
than 10 days prior to such Special Record Date, or be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in

the Indenture. Payments of principal shall be made upon the surrender of this
Security at the option of the Holder at the office of the Paying Agent, or at
such other office or agency of the Company as may be designated by it for such
purpose in the Borough of Manhattan, The City of New York or Western Europe, in
such coin or currency of The United States of America as at the time of payment
shall be legal tender for the payment of public and private debts, or at such
other offices or agencies as the Company may designate. Payment of interest on
this Security may be made by United States Dollar check drawn on a bank in the
Borough of Manhattan, The City of New York, mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register, or, upon
written application by the Holder to the Registrar setting forth wire
instructions not later than the relevant Record Date, by wire transfer to a
United States Dollar account maintained by the Holder with a bank in the Borough
of Manhattan, The City of New York (provided that such Holder shall have
furnished wire instructions in writing to any Paying Agent no later than 15 days
prior to the relevant payment date).

               1. The Company will pay to the Holder of this Security who is a
United States Alien (as defined below) such additional amounts ("Additional
Amounts") as may be necessary in order that every net payment of the principal
of, premium, if any, and interest on this Security (including payment on
redemption or repurchase), and any cash payments made in lieu of issuing
fractional conversion Shares upon conversion of this Security, after deduction
or withholding for or on account of any present or future tax, assessment or
governmental charge imposed upon or as a result of such payment by the United
States or any political subdivision or taxing authority thereof or therein, will
not be less than the amount provided for in this Security to be then due and
payable; provided, however, that the foregoing obligation to pay Additional
Amounts will not apply to any one or more of the following:

                  (a) any tax, assessment or other governmental
charge which would not have been so imposed but for (i) the existence of any
present or former connection between such Holder or the beneficial owner (or
between a fiduciary, settlor, beneficiary, member, stockholder of or possessor
of a power over such Holder, if such Holder is an estate, a trust, a partnership
or a corporation) and the United States or any political subdivision or taxing
authority thereof or therein, including, without limitation, such Holder or
beneficial owner (or such fiduciary, settlor, beneficiary, member, stockholder
or possessor) being or having been a citizen or resident of the United States or
treated as a resident thereof, or being or having been engaged in trade or
business therein or being or having been present therein, or having or having
had an office, fixed place of business or permanent establishment therein, (ii)
such Holder's or beneficial owner's present or former status as a



                                       3

organization described in Section 1443 of the Code, a controlled foreign
corporation or a passive foreign investment company for United States tax
purposes, or a corporation which accumulates earnings to avoid United States
federal income tax, (iii) such Holder or beneficial owner (or such fiduciary,
settlor, beneficiary, member, stockholder or possessor) is considered as having
made an election, the effect of which is to make payments of principal of,
premium, if any, and interest on this Security subject to United States federal
income tax; provided, however, if failure to make such election, would result in
a higher income tax liability related to this Security then such Holder shall be
deemed not to have made such election, or (iv) such Holder's status as a bank
extending credit pursuant to a loan agreement entered into in the ordinary
course of business;

               (b) any tax, assessment or other governmental charge which would
not have been so imposed but for the presentation by the Holder of this Security
for payment on a date more than 10 days after the date on which such payment
became due and payable or the date on which payment thereof is duly provided,
whichever occurs later;

               (c) any estate, inheritance, gift, sales, transfer or personal or
intangible property or any similar tax, assessment or governmental charge;

               (d) any tax, assessment or other governmental charge which would
not have been imposed but for the failure to comply with any certification,
information, documentation or other reporting requirements concerning the
nationality, residence, identity or present or former connection with the United
States of the Holder or beneficial owner of this Security, if such compliance is
required by statute, regulation or ruling or other administrative action of the
United States or any political subdivision or taxing authority thereof or
therein as a precondition to relief or exemption from such tax, assessment or
other governmental charge;

               (e) any tax, assessment or other governmental charge which is
payable otherwise than by deduction or withholding from payments of principal
of, premium, if any, or interest on this Security;

               (f) any tax, assessment or other governmental charge imposed on
interest received by a Person holding, actually or constructively, 10% or more
of the total combined voting power of all classes of capital stock of the
Company entitled to vote;

               (g) any tax, assessment or other governmental charge required to
be withheld by any Paying Agent from any payment of



                                       4
<PAGE>   113

the principal of, premium, if any, or interest on this Security, if such payment
can be made without such withholding by any other Paying Agent;

               (h) any tax, assessment or other governmental charge imposed on a
Holder that is not a beneficial owner of this Security or that is a partnership
or a fiduciary, but only to the extent that any beneficial owner or beneficiary
or settlor with respect to the fiduciary or member of the partnership would not
have been entitled to the payment of Additional Amounts had the beneficial
owner, beneficiary, settlor or member directly received its beneficial or
distributive share of payments on this Security; and

               (i) any combination of items (a), (b), (c), (d), (e), (f), (g)

purposes, (a) a foreign corporation; (b) a nonresident alien individual; (c) an

assessment or other governmental charge imposed by any government or any
political subdivision or taxing authority thereof or therein. Whenever in this
Security there is a reference, in any context, to the payment of the principal

Amounts are, were or would be payable in respect of such Security and express
reference to the payment of Additional Amounts (if applicable) in any provisions
of this Security shall not be construed as excluding reference to Additional
Amounts in those provisions of this Security where such express reference is not
made.

                                [FORM OF REVERSE]


               1. This Security is one of a duly authorized issue of securities
of the Company designated as its 6% Convertible Subordinated Debentures due 2005
(herein called the "Securities"), limited in aggregate principal amount to
$40,000,000 (except for PIK Debentures issued pursuant to Section 2.07 of the
Indenture), issued and to be issued under an Indenture, dated July 23, 1998
(herein called the "Indenture"), between the Company and American Stock Transfer
and Trust, as Trustee (herein called the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the holders of Senior Indebtedness, and the Holders of the Securities and of the
terms upon which the Securities are, and are to be, authenticated and delivered.
The Securities are issuable in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000. A Holder may transfer
or exchange Securities in accordance with the Indenture. The Registrar or
Transfer Agent may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents or certificates and to pay any taxes and fees
required by law or permitted by the Indenture.

               2. Prior to January 31, 2000, this Security will not be
redeemable at the option of the Company. On and after that date and prior to
Maturity, the Company may redeem this Security for cash in whole or in part (in
any integral multiple of $1,000), upon not less than 30 nor more than 60 days'
notice to the Holders of the Securities prior to the Redemption Date, at the
Redemption Prices of the Securities, expressed as a percentage of the principal
amount of the Securities to be redeemed, as set forth in the following table,
during each 12- month period beginning on the date specified in such table, in
each case plus accrued and unpaid interest to the Redemption Date (subject to
the right of Holders of record on the relevant Record Date to receive interest
due on an Interest Payment Date).

               In case of a redemption of the Securities in part, selection of
the Securities for redemption will be made by the Trustee, on a pro rata basis,
by lot or such other method as the Trustee shall deem fair and appropriate.

               3. If as a result of any change in, or amendment to, the laws
(including any regulations or rulings promulgated thereunder) of the United
States or any political subdivision or taxing authority thereof or therein
affecting taxation, or any change in, or amendment to, the application or
official interpretation of such laws, regulations or rulings (collectively, a
"Tax Law Change"), the Company has or will become obligated to pay to the Holder
of any Security Additional Amounts (as described in Paragraph 1 on the face of
this Security) and such obligation cannot be avoided by the Company taking
reasonable measures available to it, then the Company may, at its option, redeem
the Securities in whole, but not in part, upon not less than 30 nor more than 90
days' notice to the Holders prior to the earliest date on which the Company
would be obligated to pay any such Additional Amounts were a payment in respect
of the Securities then due, provided that at the time such notice of redemption
is given, such obligation to pay such Additional Amounts remains in effect. Any
redemption of Securities pursuant to this Paragraph 3 shall be made at a
Redemption Price equal to 100% of the principal amount plus accrued and unpaid
interest to the Redemption Date and any Additional Amounts then payable. Prior
to the giving of any notice of redemption pursuant to this Paragraph, the
Company shall deliver to the Trustee (a) an Officers' Certificate stating that
the Company is entitled to effect such redemption and setting forth a statement
of facts showing that the conditions precedent to the right of the Company so to
redeem have occurred and (b) an Opinion of Counsel to the effect that the legal
conditions precedent to the right of the Company to effect such redemption have
occurred. In the case of the occurrence of a Tax Law Change, the Company's right
to redeem the Securities shall continue as long as the Company is obligated to
pay such Additional Amounts, notwithstanding that the Company shall have made
payments of Additional Amounts specified in such second paragraph.

               4. In the event of a redemption of less than all of the
Securities, the Company will not be required (a) to register the transfer or
exchange of Securities for a period of 15 days immediately preceding the date
notice is given identifying the serial numbers of the Securities called for such
redemption, or (b) to register the transfer or exchange of any Security, or
portion thereof, called for redemption.

<PAGE>   117


               5. In any case where the Stated Maturity for the payment of the
principal of, premium, if any, or interest, including Additional Amounts, on any
Security or the last day on which a Holder of a Security has a right to convert
his Security shall be, at any Place of Payment or Place of Conversion, as the
case may be, a day on which banking institutions at such Place of Payment or
Place of Conversion are authorized or obligated by law or executive order to
close, then payment of principal, premium, if any, or interest, including
Additional Amounts, or delivery for conversion of such Security need not be made
on or by such date at such place but may be made on or by the next succeeding
day at such place which is not a day on which banking institutions are
authorized or obligated by law or executive order to close, with the same force
and effect as if made on the date for such payment or the date fixed for
redemption, or by such last day for conversion, and interest shall accrue on the
amount so payable for the period after such date.

               6. Subject to and upon compliance with the provisions of the
Indenture, the Holder of this Security is entitled, at his option, at any time
on and after November 30, 1998, and on or before the close of business on July
31, 2005 (the Stated Maturity of the principal amount of this Security), or in
case this Security or a portion hereof is called for redemption or the Holder
hereof has exercised his right to require the Company to repurchase this
Security or a portion thereof, then, in respect of this Security until and
including, but (unless the Company defaults in making the payment due upon
redemption or repurchase, as the case may be) not after, the close of business
on the Redemption Date or the Purchase Date, as the case may be, to convert this
Security (or any portion of the amount hereof that is an integral multiple of
$1,000) into fully paid and nonassessable shares of Common Stock of the Company
("Conversion Shares") at an initial Conversion Price of $14.3125 for each
Conversion Share (or at the then current adjusted Conversion Price, if an
adjustment has been made as provided in the Indenture) by surrender of this
Security, duly endorsed or assigned to the Company or in blank and, in case such
surrender shall be made during the period from the close of business of any
Regular Record Date next preceding any



                                       3
<PAGE>   118


Interest Payment Date to the opening of business on such Interest Payment Date
("Interest Period"), also accompanied by payment in United States currency of an
amount equal to the interest payable on such Interest Payment Date on the
principal amount of this Security then being converted, and also a conversion
notice duly executed, to the Company at Banque International a Luxembourg S.A.
in Luxembourg, or at such other office or agency of the Company as may be
designated by it for such purpose in the State of New York or Western Europe
(each a "Conversion Agent"); except that if this Security or any portion hereof
has been called for redemption and, pursuant to Section 10.01 of the Indenture,
as a result of such redemption the right to convert this Security or such
portion terminates after the Regular Record Date preceding any Interest Payment
Date and on or before such Interest Payment Date, then, notwithstanding such
conversion, the interest payable on such Interest Payment Date will be paid to
the registered Holder of this Security on such Regular Record Date. In such
event, this Security, when surrendered for conversion, shall be accompanied by
payment in United States currency of an amount equal to the difference between
(i) the interest on the principal amount of this Security or such portion hereof
payable on such Interest Payment Date and (ii) the amount of accrued interest on
the principal amount of this Security or portion hereof to but not including the
date of conversion. Subject to the aforesaid requirement for payment and, in the
case of a conversion after the Regular Record Date preceding any Interest
Payment Date and on or before such Interest Payment Date, to the right of the
Holder of this Security (or any Predecessor Security) of record at such Regular
Record Date to receive an installment of interest (with certain exceptions
provided in the Indenture), payment shall be made on conversion, for interest
accrued hereon from the Interest Payment Date preceding the date of conversion
to the Conversion Date. No payment or adjustment is to be made for dividends on
the Common Stock issued on conversion hereof. The Company shall thereafter
deliver to the Holder the fixed number of Conversion Shares of Common Stock
(together with any cash adjustment, as provided in the Indenture) into which
this Security is convertible and such delivery will be deemed to satisfy the
Company's obligation to pay the principal amount of this Security.

               No fractions of shares or scrip representing fractions of shares
will be issued on conversion, but instead of any fractional interest (calculated
to the nearest 1/100th of a share) the Company shall pay a cash adjustment as
provided in the Indenture. The Conversion Price is subject to adjustment as
provided in the Indenture. In addition, the Indenture provides that in case of
certain consolidations or mergers to which the Company is a party or the
transfer of all or substantially all of the property and assets of the Company,
the Indenture shall be amended, without the consent of any Holders of
Securities, so that this Security, if then Outstanding, will be convertible
thereafter, during the period this Security shall be convertible as specified
above, only into the kind and amount of securities, cash and other property
receivable upon such consolidation, merger or transfer by a holder of the number
of shares of Common Stock of the Company into which this Security could have
been converted immediately prior to such consolidation, merger or transfer.

               7. If a Change in Control occurs, the Holder of this Security
shall have the right, in accordance with the provisions of the Indenture, to
require the Company to repurchase all or a portion of such Holder's Securities
specified in a Change in Control Purchase Notice for cash at a Purchase Price
equal to 100% of the principal amount thereof plus accrued and unpaid



                                       4
<PAGE>   119


interest to the Purchase Date, provided that any portion of this Security to be
repurchased is an authorized denomination. Whenever in this Security there is a
reference, in any context, to the principal of any Security as of any time, such
reference shall be deemed to include reference to the Purchase Price payable in
respect of such Security to the extent that such Purchase Price is, was or would
be so payable at such time, and express reference of the Purchase Price in any
provision of this Security shall not be construed as excluding the Purchase
Price in those provisions of this Security when such express reference is not
made.

               Within 30 days after the occurrence of a Change in Control, the
Company is obligated to give to all Holders of record of the Securities notice,
as provided in the Indenture (the "Company Notice"), of the occurrence of such
Change in Control and of the Repurchase Right arising as a result thereof. The
Company must also deliver a copy of the Company Notice to the Trustee. To
exercise the purchase right, a Holder of such Securities must deliver on or
before the 45th day after the date of the Company Notice, a Change in Control
Purchase Notice to the Trustee of the Holder's exercise of such right, together
with the Securities with respect to which the right is being exercised.

               Under the Indenture, a "Change in Control" of the Company is
deemed to have occurred at such time as (i) any person (as the term "person" is
used in Section 13(d)(3) or Section 14(d)(2) of the Exchange Act), other than
the Company, any Company Subsidiary, Robert J. Skandalaris or any employee
benefit plan of either the Company or any Company Subsidiary, files a Schedule
13D or 14D-1 under the Exchange Act (or any successor schedule, form or report)
disclosing that such person has become the beneficial owner of 50% or more of
the total voting power in the aggregate of all classes of capital stock of the
Company then outstanding normally entitled to vote in elections of directors,
with certain exceptions, or (ii) there shall be consummated any consolidation or
merger of the Company (a) in which the Company is not the continuing or
surviving corporation (other than any consolidation or merger effected primarily
to change the jurisdiction of incorporation of the Company) or (b) pursuant to
which the Common Stock would be converted into cash, securities or other
property, in each case, other than a consolidation or merger of the Company in
which the holders of Common Stock immediately prior to the consolidation or
merger have, directly or indirectly, at least a majority of the total voting
power in the aggregate of all classes of capital stock of the continuing or
surviving corporation normally entitled to vote in elections of directors
immediately after the consolidation or merger. The Indenture does not permit the
Board of Directors to waive the Company's obligation to purchase Securities at
the option of a Holder in the event of a Change in Control of the Company.

               The Company will comply with the provisions of Rule 13e-4, Rule
14e-1 and any other tender offer rules under the Exchange Act which may then be
applicable, and will file Schedule 13E-4 or any other schedule required
thereunder in connection with any offer by the Company to purchase Securities at
the option of the Holders thereof upon a Change in Control.

               8. In the event of redemption, repurchase or conversion of this
Security in part only, a new Security or Securities for the unredeemed,
unrepurchased or unconverted portion hereof will be issued in the name of the
Holder hereof.

               9. Each Holder of this Security, by acceptance hereof,
acknowledges and agrees to the provisions of the Registration Rights Agreement
among the Company and the Placement Agents (the "Registration Rights
Agreement"), including, without limitation, the obligations of the Company to
pay interest on this Security at the increased rates specified therein upon the
occurrence of certain defaults by the Company in complying with certain
covenants contained in the Registration Rights Agreement and the obligations of
the Holders with respect to a "Shelf Registration Statement" and the
indemnification of the Company to the extent provided in the Registration Rights
Agreement.

               The following is a summary of the interest rate increase
provisions of the Registration Rights Agreement, which summary does not purport
to be complete and is subject to, and qualified in its entirety by reference to
the detailed provisions of the Registration Rights Agreement.

               The Company agrees, under the Registration Rights Agreement and
subject thereto, for the benefit of the Holders of the Securities and their
successors and transferees that (i) it will, at its cost, file a Shelf
Registration Statement with the Commission with respect to resales of Conversion
Shares by November 30, 1998, (ii) it will use its best efforts to have such
Shelf Registration Statement declared effective by the Commission by January 31,
1999, and (iii) it will use its best efforts to maintain such Shelf Registration
Statement continuously effective under the Securities Act to permit the
prospectus included the Shelf Registration Statement to be used by a holder of
Conversion Shares for a period of two years from the Final Closing Date or a
shorter period, which shorter period will terminate when all of the Conversion
Shares have been sold pursuant to the Shelf Registration Statement or Rule 144
under the Securities Act (the "Shelf Registration Period"), provided that the
Company may suspend the use of the Shelf Registration Statement for a period not
to exceed 45 days in any 12 month period (during the Shelf Registration Period)
for valid business reasons, including acquisitions and divestitures of assets,
filings with the Commission, pending corporate developments and similar reasons.




                                       6
<PAGE>   121

               If the Company defaults in complying with clause (i) above then,
at such time, the interest rate on the Securities (the "Initial Rate") will
increase by 25 basis points. Such increase will remain in effect until the date
on which such Shelf Registration Statement is filed, on which date the interest
rate on the Securities will revert to the Initial Rate (plus any increases in
the Initial Rate pursuant to the following sentence). If the Shelf Registration
Statement is not declared effective as provided in clause (ii) above, then, at
such time, and on each successive 30th day following such time, the interest
rate on the Securities (which interest rate will be the sum of the Initial Rate
plus any increase in such interest rate pursuant to a default in complying with
clause (i) above plus any increases pursuant to this sentence) will increase by
an additional 25 basis points; provided, however, that the Initial Rate will not
increase by more than 75 basis points pursuant to this sentence and will not
increase by more than 100 basis points pursuant to this sentence and a default
in complying with clause (i) above. Such increase or increases will remain in
effect until the date on which the Shelf Registration Statement is declared
effective, on which date the interest rate on the Securities will revert to the
Initial Rate. If the Company fails to keep the Shelf Registration continuously
effective or useable for the period specified in clause (iii) above, then at
such time as the Shelf Registration Statement is no longer effective or useable,
and on each successive 30th day following such time, and until the earliest of
(a) the date that the Shelf Registration Statement is again deemed effective,
(b) the date that is the second anniversary of the Final Closing Date (or, in
the event that Rule 144(k) under the Securities Act is amended to provide for a
shorter holding period, until the end of such shorter holding period), and (c)
the date as of which all the Conversion Shares have been sold pursuant to the
Shelf Registration Statement or Rule 144, the interest rate on the Securities
will increase by 25 basis points; provided that the interest rate on the
Securities will not increase by more than 100 basis points pursuant to a default
in compliance with clause (ii) above and this sentence. Such increase or
increases will remain effective until the Shelf Registration Statement is again
effective and useable in accordance with clause (iii) above, on which date, the
interest rate on the Securities will revert to the Initial Rate. Notwithstanding
anything to the contrary in the Registration Rights Agreement, a default in
compliance with clause (iii) above will not be deemed to have occurred and be
continuing by reason of a suspension in use of the Shelf Registration Statement
for valid business reasons to the extent set forth above.

               10. The indebtedness evidenced by this Security is, to the extent
and in the manner provided in the Indenture, subordinate and subject in right of
payment to the prior payment in full of all Senior Indebtedness of the Company,
and this Security is issued subject to such provisions of the Indenture with
respect thereto. Each Holder of this Security, by accepting



                                       7
<PAGE>   122


the same, (a) agrees to and shall be bound by such provisions, (b) authorizes
and directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination so provided and (c) appoints the
Trustee his or its attorney-in-fact for any and all such purposes.

               11. If an Event of Default shall occur and be continuing, the
principal of all the Securities, together with accrued interest to the date of
declaration, may be declared due and payable in the manner and with the effect
provided in the Indenture. Upon the indefeasible payment in full in cash (i) of
the amount of principal so declared due and payable, together with accrued
interest to the date of declaration, and (ii) interest on any overdue principal
and overdue interest, all of the Company's obligations in respect of the payment
of the principal of and interest on the Securities shall terminate.

               12. The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities under
the Indenture at any time by the Company and the Trustee with the written
consent of the Holders of a majority in principal amount of the Securities at
the time outstanding. The Indenture also contains provisions permitting the
Holders of a majority in principal amount of the Securities at the time
outstanding, on behalf of the Holders of all the Securities, to waive compliance
by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver
by the Holder of this Security shall be conclusive and binding upon such Holder
and upon all future Holders of this Security and of any Security issued in
exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Security or such other Security. Subject to certain
exceptions set forth in the Indenture, without the consent of any Holder, the
Company and the Trustee may amend the Indenture or the Securities to evidence
the succession of another Person to the Company and the assumption by such
successor to the covenants and obligations of the Company in the Indenture or
this Security, to cure any ambiguity, omission, defect or inconsistency, to add
guarantees or secure the Securities, to add to the covenants of the Company for
the benefit of Holders or to surrender any right or power conferred upon the
Company, to make provision with respect to conversion rights of Holders in
accordance with Section 10.12 of the Indenture, or to make certain changes in
the subordination provisions.

               13. No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of, premium,
if any, and interest on (including Additional Amounts, as described on the face
hereof) this Security at the times, places and rate, and in



                                       8
<PAGE>   123


the currency herein prescribed or to convert this Security as provided in the
Indenture.

               14. As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of Securities is registrable on the
Security Register upon surrender of a Security for registration of transfer (a)
at the Corporate Trust Office of the Trustee or at such other office or agency
of the Company as may be designated by it for such purpose in the Borough of
Manhattan, The City of New York, or (b) subject to any laws or regulations
applicable thereto and to the right of the Company to terminate the appointment
of any Transfer Agent, at the office of Banque Internationale a Luxembourg S.A.,
as the Company's Transfer Agent in Luxembourg or at such other offices or
agencies as the Company may designate, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Registrar duly executed by, the Holder thereof or his attorney duly authorized
in writing, and thereupon one or more new Securities, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees by the Registrar. No service charge shall
be made for any such registration of transfer or exchange, but the Company may
require payment of a sum sufficient to recover any tax or other governmental
charge payable in connection therewith.

               15. Prior to due presentation of a Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Security is registered, as the owner
thereof for all purposes, whether or not such Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

               16. THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, UNITED STATES OF
AMERICA, WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS.

               (a) The Company shall prepare and, not later than November 30,
1998, shall file with the SEC, and thereafter shall use its best efforts to
cause to be declared effective under the Securities Act as soon as possible
thereafter, and in no event later than January 31, 1999, a Shelf Registration

described in the Shelf Registration Statement, which shall be substantially as
set forth on Exhibit A attached hereto and made a part hereof.

               (b) The Company shall use its best efforts to keep the Shelf

the Final Closing Date or such shorter period that will terminate when all the
Registrable Securities have been sold pursuant to the Shelf Registration
Statement or Rule 144 (in any such case, such period being called the "Shelf
Registration Period"). The Company shall be deemed not to have used its best

                                      -4-
<PAGE>   5

unless such action is (i) required by applicable law or (ii) pursuant to Section
2(c) hereof, and, in either case, so long as the Company promptly thereafter
complies with the requirements of Section 3(i) hereof, if applicable.

               (c) The Company may suspend the use of the Shelf Registration
Statement for a period not to exceed 45 days in any 12 month period for valid
business reasons (not including avoidance of the Company's obligations
hereunder), including the acquisition or divestiture of assets, public filings
with the SEC, pending corporate developments and similar events.

               3. Registration Procedures. In connection with any Shelf
Registration Statement, the following shall apply:

               (a) The Company shall ensure that (i) any Shelf Registration
Statement and any amendment thereto and any Prospectus forming part thereof and
any amendment or supplement thereto complies in all material respects with the
Securities Act and the rules and regulations thereunder, (ii) any Shelf
Registration Statement and any amendment thereto does not, when it becomes
effective, contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and (iii) any Prospectus forming part of the Shelf
Registration Statement, and any amendment or supplement to such Prospectus, does
not include an untrue statement of a material fact or omit to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

               (b) (1) The Company shall advise the Holders and, if requested by
such Holder, confirm such advice in writing:

                      (i) when a Shelf Registration Statement and any amendment
thereto has been filed with the SEC and when the Shelf Registration Statement or
any post-effective amendment thereto has become effective; and

                      (ii) of any request by the SEC for amendments or
supplements to the Shelf Registration Statement or the Prospectus included
therein or for additional information.

               (2) The Company shall advise the Holders and, if requested by any
such Holder, confirm such advice in writing:

               (i) of the issuance by the SEC of any stop order suspending the
               effectiveness of the Shelf Registration Statement or the
               initiation of any proceedings for that purpose;

               (ii) of the receipt by the Company of any notification with
               respect to the suspension of the qualification of 


                                      -5-
<PAGE>   6

               the securities covered by the Shelf Registration Statement for
               sale in any jurisdiction or the initiation or threatening of any
               proceeding for such purpose; and

               (iii) of the suspension of the use of the Prospectus pursuant to
               Section 2(c) hereof or of the happening of any event that
               requires the making of any changes in the Shelf Registration
               Statement or the Prospectus so that, as of such date, the
               statements therein are not misleading and do not omit to state a
               material fact required to be stated therein or necessary to make
               the statements therein not misleading (which advice shall be
               accompanied by an instruction to suspend the use of the
               Prospectus until the requisite changes have been made).

               (c) The Company shall use its reasonable best efforts to obtain
the withdrawal of any order suspending the effectiveness of any Shelf
Registration Statement at the earliest possible time.

               (d) The Company shall furnish to each Holder, without charge, at
least one copy of the Shelf Registration Statement in the form declared
effective by the SEC and any post-effective amendment thereto, including
financial statements and schedules (if incorporated by reference), and, if the
Holder so requests in writing, all exhibits (including those incorporated
therein by reference).

               (e) The Company shall, during the Shelf Registration Period,
deliver to each Holder, without charge, as many copies of the Prospectus
(including each preliminary Prospectus) included in such Shelf Registration
Statement and any amendment or supplement thereto as such Holder may reasonably
request; and the Company consents to the use, in compliance with the terms of
this Agreement, of the Prospectus or any amendment or supplement thereto by each
of the Holders of Registrable Securities in connection with the offering and
sale thereof.

               (f) Prior to any offering of Registrable Securities pursuant to
any Shelf Registration Statement, the Company shall register or qualify or
cooperate with the Holders thereof and their respective counsel in connection
with the registration or qualification of such securities for offer and sale
under the securities or blue sky laws of such jurisdictions in the United States
as any such Holders reasonably request in writing, and do any and all other acts
or things necessary or advisable to enable the offer and sale in such
jurisdictions of the Registrable Securities; provided, however, that the Company
will not be required to qualify generally to do business in any jurisdiction
where it is not then so qualified or to take any action which would subject it
to general service of process or to taxation in any such jurisdiction where it
is not then so subject.


                                      -6-
<PAGE>   7

               (g) The Company shall use its reasonable best efforts to as
promptly as practicable list the Registrable Securities on each national
securities exchange on which the Shares are then listed, subject to official
notice of issuance.

               (h) The Company shall cooperate with the Holders to facilitate
the timely preparation and delivery of certificates representing the Registrable
Securities free of any restrictive legends and in such denominations and
registered in such names as Holders may request prior to sales of Registrable
Securities pursuant to the Shelf Registration Statement.

               (i) Upon the occurrence of any event contemplated by paragraph
(b)(2)(iii) above, the Company shall, if required pursuant to the Act or
paragraph (b)(2)(iii) above, promptly prepare a post-effective amendment to the
Shelf Registration Statement or an amendment or supplement to the related
Prospectus or file any other required document so that, as thereafter delivered
to purchasers of the Registrable Securities, the Prospectus will not include an
untrue statement of a material fact or omit to state any material fact necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading.

               (j) The Company may require each Holder to furnish to the Company
with such information regarding the Holder and the distribution of such
securities as the Company may from time to time reasonably require for inclusion
in such Shelf Registration Statement. Any Holder who fails to provide such
information within a reasonable time after receiving such request shall not be
entitled to use the Prospectus.

               (k) The Company shall enter into such agreements and take all
other appropriate actions in order to expedite or facilitate the registration or
the disposition of the Registrable Securities.

               (l) The Company shall (i) make reasonably available for
inspection by the Holders, and any attorney, accountant or other agent retained
by the Holders, all relevant financial and other records, pertinent corporate
documents and properties of the Company and its subsidiaries in connection with
such Shelf Registration Statement as is customary for similar due diligence
examinations; and (ii) cause the Company's officers directors and employees to
supply all relevant information reasonably requested by the Holders or any such
attorney, accountant or agent in connection with such Shelf Registration
Statement as is customary for similar due diligence examinations; provided,
however, that any information that is designated in writing by the Company, in
good faith, as confidential at the time of delivery of such information shall be
kept confidential by the Holders or any such 


                                      -7-
<PAGE>   8

attorney, accountant or agent, unless disclosure thereof is made in connection
with a court proceeding or required by law, or such information has become
available (not in violation of this agreement) to the public generally or
through a third party without an accompanying obligation of confidentiality, and
the Company shall be entitled to request that such Holders sign a
confidentiality agreement to the foregoing effect.

               4. Use of Prospectus. The Holders may not use the Prospectus, in
each case after notice by the Company of the applicable event, (A) during any
period of suspension referred to in Section 2(c), (B) during any period when a
stop order is in effect as referred to in Section 3(b)(2)(i), (C) in the
applicable jurisdiction during any period when the qualification of the
Registrable Securities has been suspended in such jurisdiction, as referred to
in Section 3(b)(2)(ii), and (D) during any suspension period referred to in
Section 3(b)(2)(iii).

               5. Registration Expenses. The Company shall be responsible for,
and shall pay in due course, all Registration Expenses. The Company shall not be
responsible for the payment of any underwriting or brokerage fees and discounts.

               6.  Additional Interest Under Certain Circumstances.

               (a) Additional interest ("Additional Interest") with respect to
all of the outstanding Debentures (the "Outstanding Debentures") shall be
assessed as follows if any of the following events occur (each event described
in clauses (i) through (iii) below being hereinafter sometimes called a
"Registration Default"):

                      (i) if by November 30, 1998, the Shelf Registration
Statement has not been filed with the SEC;

                      (ii) if by January 31, 1999, the Shelf Registration
Statement has not been declared effective by the SEC; or

                      (iii) if after the Shelf Registration Statement is
declared effective, (A) such Registration Statement thereafter ceases to be
effective before the second anniversary of Final Closing Date (or, in the event
that Rule 144(k) under the Securities Act is amended to provide for a shorter
holding period, until the end of such shorter period) or the date as of which
all of the Registrable Securities are sold pursuant to the Shelf Registration
Statement or Rule 144; or (B) such Registration Statement or the related
prospectus may no longer be used because either (1) any event occurs as a result
of which the related Prospectus forming part of such Registration Statement
would include any untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not 


                                      -8-
<PAGE>   9

misleading, or (2) it shall be necessary to amend such Registration Statement or
supplement the related prospectus, to comply with the Securities Act or the
Exchange Act or the respective rules thereunder.

               (b) (i) If the Shelf Registration Statement has not been filed
with the SEC within the time period described in clause (a)(i) above, Additional
Interest shall accrue on the Outstanding Debentures over and above the interest
set forth in the title of the Outstanding Debentures as follows: the per annum
interest rate on the Outstanding Debentures will increase by 25 basis points,
such increase remaining in effect until the date on which such Shelf
Registration Statement is filed, on which date the interest rate on the
Outstanding Debentures will revert to the interest rate originally borne by the
Outstanding Debentures, plus any increase in such rate pursuant to clause
(b)(ii) below.

               (ii) If the Shelf Registration Statement has not been declared
effective by the SEC within the time period described in clause (a)(ii) above,
then, at such time and on each date that is the successive 30th day following
such time, the per annum interest rate on the Outstanding Debentures (which
interest rate will be the original interest rate on the Outstanding Debentures
plus any increase or increases in such interest rate pursuant to clause (b)(i)
above and pursuant to this clause) will increase by an additional 25 basis
points; provided, however, that the per annum interest rate may not increase by
more than 75 basis points pursuant to this clause and may not increase by more
than 100 basis points pursuant to this clause and clause (b)(i) above. Such
increase or increases will remain in effect until the date on which such Shelf
Registration Statement is declared effective, on which date the interest rate on
the Outstanding Debentures will revert to the interest rate originally borne by
the Outstanding Debentures, plus any Additional Interest that may be payable
pursuant to clause (b)(iii) below.

               (iii) If the Company fails to keep the Shelf Registration
Statement continuously effective or usable for the period specified in clause
(a)(iii) above, then at such time as the Shelf Registration Statement is no
longer effective or usable, as the case may be, and on each date thereafter that
is the successive 30th day subsequent to such time and until the earliest of (A)
the date that the Shelf Registration Statement is again deemed effective or
usable, as the case may be, (B) the date that is the second anniversary of the
Final Closing Date (or, in the event that Rule 144(k) under the Securities Act
is amended to provide for a shorter holding period, until the end of such
shorter period) and (C) the date as of which all of the Registrable Securities
have been sold pursuant to the Shelf Registration Statement or Rule 144, the per
annum interest rate on the Outstanding Debentures will increase by 25 basis
points; provided, however, that the per annum interest rate may not increase by
more than 100 basis points pursuant to this clause (b)(iii).


                                      -9-
<PAGE>   10

               (c) Anything herein contained to the contrary notwithstanding, a
Registration Default referred to in Section 6(a)(iii)(B) shall be deemed not to
have occurred and be continuing solely as a result of the suspension by the
Company of the use of the Shelf Registration Statement pursuant to the
provisions of Section 2(c) hereof.

               (d) Any amounts of Additional Interest due pursuant to clause
(b)(i), (b)(ii) or (b)(iii) of Section 6 above will be payable on the regular
interest payment dates with respect to the Outstanding Debentures. The amount of
Additional Interest will be determined by multiplying the applicable Additional
Interest rate by the principal amount of the Outstanding Debentures, multiplied
by a fraction, the numerator of which is the number of days such Additional
Interest rate was applicable during such period (determined on the basis of a
360-day year comprised of twelve 30-day months), and the denominator of which is
360.

                   7.  Indemnification and Contribution.

               (a) In connection with any Shelf Registration Statement, the
Company agrees to indemnify and hold harmless each Holder, each Affiliate of
such Holder, the directors, partners, officers, employees and agents of each
such Holder and each person who controls any such Holder within the meaning of
either the Securities Act or the Exchange Act against any and all losses,
claims, damages or liabilities, joint or several, to which they or any of them
may become subject under the Act, the Exchange Act or other Federal or state
statutory law or regulation, at common law or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of a material
fact contained in the Shelf Registration Statement as originally filed or in any
amendment thereof, or in any preliminary Prospectus or Prospectus, or in any
amendment thereof or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
agrees to reimburse each such indemnified party, as incurred, for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that (i) the Company will not be liable in any case to the extent that any such
loss, claim, damage or liability arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made
therein in reliance upon and in conformity with written information furnished to
the Company by or on behalf of any such Holder specifically for inclusion
therein, (ii) the Company will not be liable to any indemnified party under this
indemnity agreement with respect to any Shelf Registration 


                                      -10-

Statement or Prospectus to the extent that any such loss, claim, damage or
liability of such indemnified party results from the use of the Prospectus
during a period when the use of the Prospectus has been suspended in accordance
with Section 2(c) hereof, provided that Holders received prior notice of such
suspension; and (iii) the Company shall not be liable to any indemnified party
with respect to any preliminary Prospectus to the extent that any such loss,
claim, damage or liability of such indemnified party results from the fact that
such indemnified party sold Registrable Securities to a person as to whom there
was not sent or given, at or prior to the written confirmation of such sale, a
copy of the Prospectus or of the Prospectus as then amended or supplemented in
any case where such delivery is required by the Securities Act, if the loss,
claim, damage or liability of such indemnified party results from an untrue
statement or omission of a material fact contained in the preliminary Prospectus
which was corrected in the Prospectus or in the Prospectus as then amended or
supplemented. This indemnity agreement will be in addition to any liability
which the Company may otherwise have. The Company also agrees to indemnify and
provide contribution to each person who may be deemed to be an underwriter (for
purposes of the Securities Act) with respect to the Registrable Securities
("Underwriters"), their officers and directors, and each person who controls
each such Underwriter, on substantially the same basis as that of the
indemnification of and contribution to the Holders provided in this Section
7(a).

               (b) By its participation in the Shelf Registration Statement,
each Holder shall be deemed to have agreed to indemnify and hold harmless (i)
the Company, (ii) each of its directors, (iii) each of its officers who signs
such Shelf Registration Statement and (iv) each person who controls the Company
within the meaning of either the Act or the Exchange Act to the same extent as
the foregoing indemnity from the Company to each such Holder, but only with
respect to written information relating to such Holder furnished to the Company
by or on behalf of such Holder specifically for inclusion in the documents
referred to in the foregoing indemnity. This indemnity agreement will be in
addition to any liability which any such Holder may otherwise have. Each Holder
shall also be deemed to have agreed to indemnify and contribute to each
Underwriter, their officers and directors, and each person who controls each
such Underwriter, on substantially the same basis as that of the indemnification
of and contribution to the Company provided in this Section 7(b). Anything in
this Agreement contained to the contrary notwithstanding, the liability of each
Holder for indemnification or contribution hereunder shall be limited to the
amount of proceeds received by such Holder in the offering giving rise to such
liability.

               (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, 


                                      -11-
<PAGE>   12

such indemnified party will, if a claim in respect thereof is to be made against
the indemnifying party under this Section 7, notify the indemnifying party in
writing of the commencement thereof; but the failure so to promptly notify the
indemnifying party will not relieve the indemnifying party from liability under
Section 7(a) or 7(b) hereof unless and to the extent that it is materially
prejudiced thereby. The indemnifying party shall be entitled to appoint counsel
of the indemnifying party's choice at the indemnifying party's expense to
represent the indemnified party in any action for which indemnification is
sought (in which case the indemnifying party shall not thereafter be responsible
for the fees and expenses of any separate counsel retained by the indemnified
party or parties except as set forth below); provided, however, that such
counsel shall be reasonably satisfactory to the indemnified party.
Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel (and local counsel) if (i) the use of counsel chosen by the
indemnifying party to represent the indemnified party would present such counsel
with a conflict of interest, (ii) the actual or potential defendants in, or
targets of, any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, (iii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of the institution of such action or (iv) the
indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party. An indemnified party shall not
settle or compromise any action for which it seeks indemnification or
contribution hereunder without the prior written consent of the indemnifying
party, which consent shall not be unreasonably withheld. An indemnifying party
will not, without the prior written consent of the indemnified parties, settle
or compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding.

               (d) In the event that the indemnity provided in Section 7(a) or
7(b) is unavailable to or insufficient to hold harmless an indemnified party for
any reason, then each applicable indemnifying party, in lieu of indemnifying
such indemnified party, shall contribute to the aggregate losses, 


                                      -12-
<PAGE>   13

claims, damages and liabilities (including legal or other expenses reasonably
incurred in connection with investigating or defending same) (collectively
"losses") to which such indemnified party may be subject in such proportion as
is appropriate to reflect the relative benefits received by such indemnifying
party, on the one hand, and such indemnified party, on the other hand, from the
Shelf Registration Statement which resulted in such losses.

               (e) The provisions of this Section 7 shall remain in full force
and effect regardless of any investigation made by or on behalf of any Holder or
the Company or any other persons who are entitled to indemnification pursuant to
the provisions of this Section 7, and shall survive the sale by a Holder of
Registrable Securities pursuant to the Shelf Registration Statement.

               8. Rule 144. As long as the Company is subject to the reporting
requirements of Section 13 or 15 of the Exchange Act, the Company shall use its
best efforts to promptly file the reports required to be filed by it pursuant to
Section 13(a) or 15(d) of the Exchange Act and the rules and regulations adopted
by the SEC thereunder. If the Company is at any time not required to file such
reports, it shall promptly make publicly available such information as is
necessary to permit sales of the Conversion Shares pursuant to Rule 144. Upon
the request of any Holder, the Company shall deliver to such Holder a written
statement as to whether it has complied with such requirements.

               9. Amendments. This Agreement may not be amended, modified or
supplemented, and waivers of or consents to departures from the provisions of
this Agreement may not be given, unless it would not have an adverse effect upon
the rights of any of the Holders and the Company has obtained the consent of
Holders then owning a majority of the Registrable Securities. In connection with
the foregoing, the Company hereby acknowledges that pursuant to the terms of the
Subscription Agreement, each of the Placement Agents is empowered to act as
attorney-in-fact for the Holders and their transferees.

               10. Successors and Assigns. This Agreement shall inure to the
benefit of, and be binding upon, the Company, the Holders and the other persons
and entities described in Section 7 hereof and their respective successors,
assigns and transferees, including, without limitation and without the need for
an express assignment, subsequent Holders.

               11. Third Party Beneficiaries. The Holders from time to time
shall each be a third party beneficiary of the agreements of the Company
contained herein. Each of BlueStone and Fleming shall have the right, but not
the obligation, to enforce such agreements directly, to the extent it determines
(in its sole discretion), that such enforcement is necessary or desirable in
order to protect the rights of the Holders.

               12. Headings. The headings which are contained in this Agreement
are for the sole purpose of convenience of reference, and shall not limit or
otherwise affect the interpretation of any of the provisions hereof.

               13. Governing Law. This Agreement shall be governed by the laws
of the State of New York applicable to contracts made and to be wholly performed
therein.

               14. Notices. All notices and other communications hereunder shall
be in writing (which shall include publication), and shall be made by hand
delivery, registered first-class mail, telecopier or any courier providing
overnight delivery, (i) if to the Company or an Initial Holder, at the address
set forth in the Subscription Agreement, (ii) if to a Holder of Shares, to the
address set forth on the books and records of the Company, and (iii) if to a
Holder of Debentures (other than an Initial Holder), in the manner provided in
the Indenture. All such notices and other communications shall be deemed to have
been duly given upon receipt or as otherwise provided in the Indenture.

               15. Entire Agreement. This Agreement sets forth the entire
agreement of the Company with respect to the subject matter hereof.

               16. Severability. In the event that any one or more of the
provisions of this Agreement, or the application thereof in any circumstances,
is held invalid, illegal or unenforceable in any respect for any reason, the
validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions of this Agreement shall not be in any
way impaired or affected thereby.

               17. Further Assurances. The Company will from time to time after
the date hereof take any and all actions, and execute, acknowledge and deliver
any and all documents and instruments, at its cost and expense, as any Holder
may from time to time reasonably request in order to more fully perfect or
protect the rights intended to be granted to it hereunder.

               18. Interpretation. As used in this Agreement, unless the context
otherwise requires: words describing the singular number shall include the
plural and vice versa; words denoting any gender shall include all genders;
words denoting natural persons shall include corporations, partnerships and
other entities, and vice versa; and the words "hereof", "herein" and
"hereunder", and words of similar import, shall refer to this Agreement as a
whole, and not to any particular provision of this Agreement.

               19. Waiver. The failure of the Company or any Holder to at any
time enforce any of the provisions of this Agreement shall not be deemed or
construed to be a waiver of any such provision, nor to in any way affect the
validity of this Agreement or any provision hereof or the right of the Company
or any Holder to thereafter enforce each and every provision of this Agreement.

               IN WITNESS WHEREOF, the undersigned has duly executed and
delivered this Agreement as of the date above written:


                                            NOBLE INTERNATIONAL, LTD.


                                            By:

                                                                       EXHIBIT A


                              PLAN OF DISTRIBUTION

               The Registrable Securities may be sold by the Holders from time
to time to or through persons who may be deemed to be underwriters within the
meaning of the Securities Act, directly to other purchasers, or through agents.
The Shelf Registration Statement is not the exclusive means for resales of
Registrable Securities (e.g., they may be sold pursuant to Rule 144). The sale
of the Registrable Securities may be effected from time to time in one or more
transactions at a fixed price or prices (which may be changed), or at market
prices prevailing at the time of sale, at prices related to such prevailing
market prices, or at negotiated prices, on such national securities exchange on
which the Registrable Securities may be listed or have unlisted trading
privileges, or in negotiated transactions, or in a combination of such methods
of sale.
