                      AMENDMENTS TO THE ORIGINAL INDENTURE


         SECTION 4.1. Section 1.1 of the Original Indenture is hereby amended to
eliminate the following provisions:

         "Attributable Debt" means, as to any particular lease under which any
Person is at the time liable, at any date as of which the amount thereof is to
be determined, the total net amount of rent required to be paid by such Person
under such lease during the remaining term thereof, discounted from the
respective due dates thereof to such date at the Composite Rate. The net amount
of rent required to be paid under any such lease for any such period shall be
the aggregate amount of the rent payable by the lessee with respect to such
period after excluding amounts required to be paid on account of maintenance and
repairs, financing services, insurance, taxes, assessments, water or electrical
rates, contingent rents (such as those based on sales) and similar charges. In
the case of any lease which is terminable by the lessee upon the payment of a
penalty, such net amount shall also include the amount of such penalty, but no
rent shall be considered as required to be paid under such lease subsequent to
the first date upon which it may be so terminated.

         "Consolidated Net Tangible Assets" shall mean, at any date, the total
assets appearing on the consolidated balance sheet of the Issuer and its
consolidated Subsidiaries for the Issuer's most recently completed fiscal
quarter, prepared in accordance with generally accepted accounting principles,
less (a) all current liabilities shown on such balance sheet and (b) Intangible
Assets. "Intangible Assets" means the value (net of applicable reserves), as
shown on or reflected in such balance sheet, of: (i) all trade names,
trademarks, licenses, patents, copyrights and goodwill; (ii) organizational or
development costs; (iii) deferred charges (other than prepaid items such as
insurance, taxes, interest, commissions, rents and similar items and tangible
assets being amortized); and (iv) unamortized debt discount and expense, less
premium.

                                       -4-

   5



         "Debt" of any Person shall mean any debt for money borrowed which is
issued, assumed, incurred or guaranteed in any manner by such Person.

         "Exempted Debt" shall mean the sum of (a) Debt of the Issuer and its
Subsidiaries incurred after the date as of which this Indenture is dated and
secured by liens created, assumed or permitted to exist pursuant to Section
3.6(b) and (b) Attributable Debt of the Issuer and its Subsidiaries in respect
of all sale and leaseback transactions entered into pursuant to Section 3.6(d).

         "Mortgage" shall have the meaning set forth in Section 3.6(a).

         "Principal Manufacturing Property" shall mean any manufacturing plant
or any testing or research and development facility of the Issuer or a
Subsidiary located in the United States of America (other than its territories
and possessions) unless, in the opinion of the Board of Directors, such plant or
facility is not of material importance to the total business conducted by the
Issuer and its consolidated Subsidiaries. Principal Manufacturing Property shall
include, without limitation, additions, improvements, replacements, repairs,
fixtures, appurtenances or component parts of any such plant or facility
attaching to or required to be attached to property or assets pursuant to the
terms of any Mortgage (including, without limitation, pursuant to any
"after-acquired property" clause or similar term thereof).

         "Restricted Subsidiary" shall mean any Subsidiary that owns or is the
lessee of any Principal Manufacturing Property; provided, however, that the term
"Restricted Subsidiary" does not include any Subsidiary acquired or organized
for the purpose of acquiring the stock or business or assets of any Person other
than the Issuer or any Restricted Subsidiary, whether by merger, consolidation,
acquisition of stock or assets or similar transaction, so long as such
Subsidiary does not acquire all or any substantial part of the business or
assets of the Issuer or any other Restricted Subsidiary.

         SECTION 4.2. Section 3.6 of the Original Indenture is hereby amended
and restated in its entirety to read as follows:

         "SECTION 3.6.   Negative Pledge; Limitation on Sale and Leaseback
