     Control Purchase Price pursuant to section 7 hereof or upon the Stated
     Maturity of this Security) or if interest (including semiannual, contingent
     or cash interest, if any) due hereon or any portion of such interest is not
     paid when due in accordance with this section, section 5 or section 11
     hereof, then in each such case the overdue amount shall, to the extent
     permitted by law, bear interest at the rate of 1.00% per annum, compounded
     semiannually, which interest shall accrue from the date such overdue amount
     was originally due to the date payment of such amount, including interest
     thereon, has been made or duly provided for. All such interest shall be
     payable on demand.

     Original Issue Discount (the difference between the Issue Price and the
     Principal Amount at Maturity of the Security), in the period during which a
     Security remains outstanding, shall accrue at 1.00% per annum, on a
     semiannual bond equivalent basis using a 360-day year composed of twelve

     Securities that are converted; provided, however that Securities
     surrendered for conversion during the period, in the case of interest in
     lieu of Original Issue Discount payable under section 11(a), semiannual
     interest payable under section 11(c) or cash interest payable under section
     1, from the close of business on any Regular Record Date immediately
     preceding any Interest Payment Date to the opening of business on such
     Interest Payment Date or, in the case of contingent interest, from the
     close of business on any date on which contingent interest accrues to the
     opening of business on the date on which such contingent interest is
     payable, shall be entitled to receive such interest in lieu of Original
     Issue Discount or semiannual, contingent or cash interest, as the case may
     be, payable on such Securities on the corresponding Interest Payment Date
     or the date on which such contingent interest is payable and (except
     Securities with respect to which the Company has mailed a notice of
     redemption) Securities surrendered for conversion during such periods must
     be accompanied by payment of an amount equal to the interest in lieu of
     Original Issue Discount or semiannual, contingent or cash interest with
     respect thereto that the registered Holder is to receive."

               (b)  The thirteenth paragraph of Section 9 of the Securities is
hereby amended by replacing it in its entirety with the following:

          at Maturity of such portion is $1,000 or an integral multiple of
          $1,000. No payment or adjustment will be made for dividends on the
          Common Stock except as provided in the Indenture. On conversion of a
          Security, that portion of accrued Original Issue Discount (or interest
          if the Company has exercised its option provided for in section 11(a)
          hereof or is required to pay interest pursuant to section 11(c)
          hereof) and cash interest payable pursuant to section 1 hereof
          attributable to the period from the Issue Date (or, if the Company has

          through the Conversion Date and (except as provided above) accrued
          contingent interest with respect to the converted Security shall not
          be cancelled, extinguished or forfeited, but rather shall be deemed to
          be paid in full to the Holder thereof through the delivery of the
          Common Stock (together with the cash payment, if any, in lieu of
          fractional shares) in exchange for the Security being converted
          pursuant to the terms hereof; and the fair market value of such shares
          of Common Stock (together with any such cash payment in lieu of
          fractional shares) shall be treated as issued, to the extent thereof,
          first in exchange for Original Issue Discount (or interest, if the
          Company has exercised its option provided for in section 11(a) hereof
          or is required to pay interest pursuant to section 11(c) hereof) and
          cash interest payable pursuant to section 1 hereof accrued through the
          Conversion Date and accrued contingent interest, and the balance, if
          any, of such fair market value of such Common Stock (and any such cash
          payment) shall be treated as issued in exchange for the Issue Price of
          the Security being converted pursuant to the provisions hereof."

               SECTION 3.06.   Amendments to Section 17 of the Securities. The
                               ------------------------------------------
first paragraph of Section 17 of the Securities is hereby amended by replacing
it in its entirety with the following:

          "Under the Indenture, Events of Default include (i) default in the
          payment of cash interest or contingent interest when the same becomes
          due and payable or of semiannual interest which becomes due and
          payable upon exercise by the Company of its option provided for in
          section 11(a) hereof or pursuant to section 11(c) hereof which default
          in any such case continues for 30 days; (ii) default in payment of the
          Principal Amount at Maturity (or, if the Securities have been
          converted to semiannual coupon notes following a Tax Event, the
          Restated Principal Amount), Issue Price plus accrued Original Issue
          Discount, Redemption Price, Purchase Price or Change in Control
          Purchase Price, as the case may be, in respect of the Securities when
          the same becomes due and payable; (iii) failure by the Company to
          comply with other agreements in the Indenture or the Securities,
          subject to notice and lapse of time; (iv) (a) failure of the Company
          to make any

                                        6



          payment by the end of any applicable grace period after maturity of
          Debt in an amount in excess of $10,000,000, or (b) the acceleration of
          Debt in an amount in excess of $10,000,000 because of a default with
          respect to such Debt without such Debt having been discharged or such
          acceleration having been cured, waived, rescinded or annulled, subject
          to notice and lapse of time; provided, however, that if any such
          failure or acceleration referred to in (a) or (b) above shall cease or
          be cured, waived, rescinded or annulled, then the Event of Default by
          reason thereof shall be deemed not to have occurred; and (v) certain
          events of bankruptcy or insolvency. If an Event of Default occurs and
          is continuing, the Trustee, or the Holders of at least 25% in
          aggregate Principal Amount at Maturity of the Securities at the time
          outstanding, may declare all the Securities to be due and payable
          immediately. Certain events of bankruptcy or insolvency are Events of
          Default which will result in the Securities becoming due and payable
          immediately upon the occurrence of such Events of Default."

               SECTION 3.07.   Notation on Securities. (a) The Securities, as
                               ----------------------
amended by the provisions of this First Supplemental Indenture, shall bear a
notation substantially to the following effect:
