         referred to in clause (iii)(A)(3) of this Section 2.1(c);

   7

         which (i) refer to a specific date, (ii) have been modified by
         transactions permitted pursuant to the Note Purchase Agreements, or
         (iii) have been specifically waived by the requisite percentage of the
         Noteholders).

SECTION 3. CONDITIONS TO EFFECTIVENESS OF THIS SECOND AMENDMENT.

               3.1. This Second Amendment shall not become effective until, and
shall become effective when, each and every one of the following conditions
shall have been satisfied:

               (a) executed counterparts of this Second Amendment, duly executed
         by the Company and the holders of at least 66-2/3% of the outstanding
         principal of the Notes, shall have been delivered to the Noteholders;

               (b) the Noteholders shall have received evidence satisfactory to
         them that the Third Amendment to the Bank Credit Agreement has been
         executed and delivered by the parties thereto; and

         in Section 2 hereof are true and correct on and with respect to the
         date hereof.

Upon receipt of all of the foregoing, this Second Amendment shall become
effective.

SECTION 4. WAIVER.

         The Company and its Subsidiaries have made certain investments which
were prohibited by the Bank Credit Agreement and which triggered events of
default under the Bank Credit Agreement. Pursuant to an amendment to the Bank
Credit Agreement, the investments were subsequently permitted and the events of
default triggered by such investments were waived. Upon and by virtue of this
Second Amendment becoming effective as herein contemplated, the Event of Default
under Section 11(f) of the Note Purchase Agreements, which Event of Default has
occurred solely as a result of the events of default under the Bank Credit
Agreement described above, and the failure of the Company to notify the
Noteholders of such Event of Default as required by Section 7.1(d) of the Note
Purchase Agreements, which failure also constitutes an Event of Default under
the Note Purchase Agreements, shall be deemed to have been waived by the
Noteholders. The Company understands and agrees that the waivers contained in
this Section 4 pertain only to the Default and Event of Default herein described
and to the extent so 





   8


described and not to any other Default or Event of Default which may exist
under, or any other matters arising in connection with, the Note Purchase
Agreements or to any rights which the Noteholders have arising by virtue of any
such other actions or matters.

SECTION 5. MISCELLANEOUS.

               5.1. This Second Amendment shall be construed in connection with
and as part of each of the Note Purchase Agreements, and except as modified and
expressly amended by this Second Amendment, all terms, conditions and covenants
contained in the Note Purchase Agreements and the Notes are hereby ratified and
shall be and remain in full force and effect.

               5.2. Any and all notices, requests, certificates and other
instruments executed and delivered after the execution and delivery of this
Second Amendment may refer to the Note Purchase Agreements without making
specific reference to this Second Amendment but nevertheless all such references
shall include this Second Amendment unless the context otherwise requires.

               5.3. The descriptive headings of the various Sections or parts of
this Second Amendment are for convenience only and shall not affect the meaning
or construction of any of the provisions hereof.

               5.4. THIS SECOND AMENDMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH NEW YORK LAW.

               5.5. The execution hereof by you shall constitute a contract
between us for the uses and purposes hereinabove set forth, and this Second
Amendment may be executed in any number of counterparts, each executed
counterpart constituting an original, but all together only one agreement.
