equity interest in, the Parent and the Company that are authorized, or issued
and outstanding as of the date set forth in such Schedule. Except as set forth

                  -
any holders of any class of securities of the Parent or the Company, (b) no
                                                                      -

          -------------------
Parent and its Subsidiaries as at March 31, 2001 and March 31, 2000, and the
related consolidated statements of income and of cash flows for the fiscal years
ended on such dates, as filed by the Parent with the United States Securities
and Exchange Commission (and reported on by and accompanied by an unqualified
report from PricewaterhouseCoopers), present fairly, in all material respects,
the consolidated financial condition of the Parent and its Subsidiaries as at
such respective dates, and the consolidated results of its operations and its
consolidated cash flows for the respective fiscal years then ended. The
unaudited consolidated balance sheet of the Parent and its Subsidiaries as at

its consolidated cash flows for the nine-month period then ended (subject to the
omission of certain footnotes and normal year-end audit and other adjustments).

thereto, have been prepared in accordance with GAAP applied consistently
throughout the periods involved (except as approved by the Chief Financial
Officer of the Parent, and disclosed in any such schedules and notes, and except
that such unaudited financial statements do not contain certain footnotes). All
material Guarantee Obligations, material contingent liabilities and liabilities
for taxes, or all material long-term leases or unusual forward or long-term
commitments, including, without limitation, any interest rate or foreign
currency swap or exchange transaction or other obligation in respect of
derivatives, which according to GAAP must be reflected in such financial
statements or the notes thereto, are so reflected.

          ------------
Agreement and the other Transaction Agreements by the Parent, the Company and
the Subsidiaries of the Company, as appropriate, and the use of the proceeds of

                      ------------------------------------

     6.1 Interest Accrual. Interest on each Note shall be computed on the basis
         ----------------
of a three hundred sixty (360) day year of twelve (12) thirty (30) day months,
and shall accrue on the unpaid principal amount of such Note from time to time
outstanding from and including the date thereof at the rate (the "Interest
Rate") of twelve percent (12%) per annum, in arrears, semi-annually on each
March 31st and September 30th (each, an "Interest Payment Date") of each year
(commencing on the later of March 31, 2002 and the Interest Payment Date next
succeeding the date of issuance of such Note) until the Principal Amount of such
Note shall have become due and payable. Any overdue installment of interest or
payment of any Principal Amount (the due date of such installment or payment to
be determined without giving effect to any grace period) shall be payable upon
demand and shall bear interest at a rate per annum equal to the lesser of (a)
the highest rate allowed by applicable law and (b) the Interest Rate plus two
percent (2%).

     6.2 Payments.
         --------

         (a) Interest Payments. The Company shall pay the accrued and unpaid
             -----------------
interest on the Notes on each Interest Payment Date, without any presentment of
the Notes by the Holders thereof and without any notation of such payment being
made thereon. With respect to each Note, payments of accrued and unpaid interest
(each, an "Interest Payment") shall be made by the Company to the Holder of such
           ----------------
Note either (i) in cash or (ii), at the option of the Company, by the issuance
             -              --
of an additional Note (A) in the form Exhibit A hereto, with such changes
                       -
therefrom, if any, as may be approved by the Company and the Holder, (B)
                                                                      -
registered in the name of such Holder, (C) bearing interest at the Interest Rate
                                        -
and (D) having a face value equal to the amount of the Interest Payment
     -
applicable to such Note. In the event that an Interest Payment is made by the
Company through the issuance of an additional Note as provided in the previous
sentence, such Interest Payment shall be deemed paid in full and shall not
constitute an overdue installment of interest.

         (b) Payment of Principal Upon Maturity. With respect to each Note, on
             ----------------------------------
the Maturity Date, the Principal Amount of such Note shall become due and
payable and shall be paid by the Company, together with any accrued and unpaid
interest on such Note, to the Holder thereof in cash.

                                       14



         (c) Mechanism for Payments in Cash. Any cash payment required to be
             ------------------------------
made by the Company under this Article VI shall be made by wire transfer of
immediately available funds to an account designated in writing by the Holder to
whom such payment is due.

         (d) Payment on Business Day Only. If any payment due on, or with
             ----------------------------
respect to, any Note shall fall due on a day other than a Business Day, then
such payment shall be made on the next succeeding Business Day following the day
on which such payment shall have so fallen due, without including the additional
days elapsed in the computation of the interest payable on such succeeding
Business Day.

     6.3 Conversion.
         ----------

         (a) Subject to and upon compliance with the provisions of this Section
6.3, at the option of the Holder thereof, any Note may be converted into fully
paid and nonassessable shares (calculated as to each conversion to the nearest
1/100th of a share) of Common Stock at the Conversion Rate, determined as
hereinafter provided, in effect at the time of conversion. Such conversion right
shall commence on the initial issuance date of each Note and expire at the close
of business on the Maturity Date. In case a Note or portion thereof is called
for redemption at the election of the Company or the Holder thereof exercises
his right to require the Company to repurchase the Note following a Change of
Control, such conversion right in respect of the Note, or portion thereof so
called, shall expire at the close of business on the Business Day prior to the
Redemption Date or the Change of Control Payment Date, as the case may be,
unless the Company defaults in making the payment due upon redemption or
repurchase, as the case may be. The rate at which shares of Common Stock shall
be delivered upon conversion (the "Conversion Rate") shall be initially three
                                   ---------------
hundred thirty three and one-third (333.33) shares of Common Stock for each
$1,000 Principal Amount of Notes. The Conversion Rate shall be adjusted in
certain instances as provided in this Section 6.3. (For the purposes of this
Agreement, an "increase" or "decrease" in the Conversion Rate means that the
number of shares of Common stock issuable upon conversion of each $1,000 of
Principal Amount of the Notes shall be increased or decreased, as appropriate.)

         (b) Mechanics of Conversion.
             -----------------------

         (i) No fractional shares of Common Stock shall be issued upon
     conversion of any Note. In lieu of any fractional shares of Common Stock
     (or other property) to which a Holder would otherwise be entitled upon
     conversion of any Note (or specified portion thereof), the Company shall
     pay such Holder cash equal to such fraction multiplied by the Current
     Market Price per share of Common Stock on the day of conversion.

                                       15



         (ii)  Before any Holder of a Note shall be entitled to convert such
     Note into Common Stock, such Holder shall surrender such Note, duly
     endorsed in blank, to the Company at the principal executive office of the
     Company (or any transfer agent designated by the Company), accompanied by
     written notice to the Company (a copy of which shall also be delivered to
     the Parent) stating therein (A) that such Holder elects to convert all or a
                                  -
     specified percentage (based on the Principal Amount and any accrued but
     unpaid interest thereon) of such Note into shares of Common Stock in
     accordance with this Agreement and (B) the name or names of the Person or
                                         -
     Persons which such Holder wishes the certificate or certificates evidencing
     the Common Stock to be issued. The Company's or Parent's delivery to the
     Holder (or its designee in the notice of conversion) of the number of
     shares of Common Stock (and cash in lieu of fractions thereof) into which a
     Note is convertible will be deemed to satisfy the Company's obligation to
     pay the Principal Amount of (and accrued but unpaid interest on) the Note.
     The Parent and the Company shall, as soon as practicable thereafter, (x)
                                                                           -
     issue and deliver to such Holder (or to his nominee or nominees) a
     certificate or certificates representing the number of shares of Common
     Stock to which such Holder shall be entitled as aforesaid, (y) deliver to
                                                                 -
     such Holder (or to his nominee or nominees) cash in lieu of any fractional
     share and (z), if less than the full Principal Amount (and accrued but
                -
     unpaid interest) evidenced by such surrendered Note is being converted, a
     new Note, duly executed and delivered by the Company, with a Principal
     Amount equal to the Principal Amount of the Note surrendered for
     conversion, plus any accrued but unpaid interest thereon, minus the portion
     of such Principal Amount (and accrued but unpaid interest) converted to
     shares Common Stock. A Note may be converted in part, but only if the
     principal amount of such Note to be converted is any integral multiple of
     $1,000 and the principal amount of such Note to remain outstanding after
     such conversion is equal to $1,000 or any integral multiple of $1,000 in
     excess thereof.

         (iii) Any conversion made under this Agreement shall be deemed to have
     been made immediately prior to the close of business on the date of
     surrender of the Note to be converted, and at such time the rights of the
     Holders of such Notes shall cease, and the Person or Persons entitled to
     receive the Common Stock issuable upon such conversion shall be treated for
     all purposes by the Parent as the record holder or holders of such Common
     Stock as of such date.

         (c)   Anti-Dilution Adjustments. The Conversion Rate shall be subject
               -------------------------
to adjustments from time to time as follows:

         (i)   In case the Parent shall pay or make a dividend or other
     distribution on shares of any class of capital stock payable in shares of
     Common Stock, the Conversion Rate in effect at the opening of business on
     the day following the date fixed for the determination of shareholders
     entitled to receive

                                       16



     such dividend or other distribution shall be increased by dividing such
     Conversion Rate by a fraction of which (x) 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 (y) the denominator shall be the
                                                -
     sum of such number of shares and the total number of shares constituting
     such dividend or other distribution, such increase to become effective
     immediately after the opening of business on the day following the date
     fixed for such determination. If, after any such date fixed for
     determination, any dividend or distribution is not in fact paid, the
     Conversion Rate shall be immediately readjusted, effective as of the date
     the Board of Directors determines not to pay such dividend or distribution,
     to the Conversion Rate that would have been in effect if such determination
     date had not been fixed. For the purposes of this Section 6.3(c)(i), the
     number of shares of Common Stock at any time outstanding shall not include
     shares held in the treasury of the Parent but shall include shares issuable
     in respect of scrip certificates issued in lieu of fractions of shares of
     Common Stock.

         (ii) In case the Parent shall issue rights, options or warrants to all
     or substantially all holders of its Common Stock or to any other Person
     (whether or not other holders of its Common Stock receive any such rights,
     options or warrants) entitling them to subscribe for or purchase shares of
     Common Stock, or securities convertible into shares of Common Stock, at a
     price per share (such price per share, the "New Price Per Share") less than
     either (A) the Current Market Price per share of the Common Stock or (B)
             -                                                             -
     the Conversion Price in effect, on the date fixed for the determination of
     stockholders entitled to receive such rights, options or warrants or, in
     the case of any other issuance (an "Issuance"), on the date of such
                                         --------
     Issuance (other than any rights, options or warrants that by their terms
     will also be issued to any Holder upon conversion of a Note into shares of
     Common Stock without any action required by the Parent or any other
     Person), the Conversion Rate in effect at the opening of business on the
     day following the date fixed for such determination or the date of such
     Issuance, as the case may be, shall be increased by dividing such
     Conversion Rate by a fraction of which (x) the numerator shall be the
                                             -
     number of shares of Common Stock outstanding at the close of business on
     the date fixed for such determination or immediately prior to such
     Issuance, as the case may be, plus the number of shares of Common Stock
     which the aggregate of the offering price of the total number of shares of
     Common Stock so offered for subscription or purchase would purchase at (1)
                                                                             -
     if the New Price Per Share is less than both such Current Market Price and
     such Conversion Price, the higher of such prices or (2) if the New Price
                                                          -
     Per Share is less than either such Current Market Price or such Conversion
     Price but not both, such price that the New Price Per Share is less than,
     (y) the denominator shall be the number of shares of Common Stock
      -
     outstanding at the close of business on the date fixed for such
     determination or immediately prior to such Issuance, as the case may be,
     plus the number of shares of Common Stock so

                                       17



         offered for subscription or purchase, such increase to become effective
         immediately after the opening of business on the day following the date
         fixed for such determination or of such Issuance, as the case may be.
         If, after any such date fixed for determination or any Issuance, any
         such rights, options or warrants are not in fact issued, or are not
         exercised, prior to the expiration thereof, the Conversion Rate shall
         be immediately readjusted, effective as of the date such rights,
         options or warrants expire, or the date the Board of Directors of the
         Parent determines not to issue such rights, options or warrants, to the
         Conversion Rate that would have been in effect if the unexercised
         rights, options or warrants had never been granted or such
         determination date had not been fixed, as the case may be. For the
         purposes of this Section 6.3(c)(ii), the number of shares of Common
         Stock at any time outstanding shall not include shares held in the
         treasury of the Company but shall include shares issuable in respect of
         scrip certificates issued in lieu of fractions of shares of Common
         Stock.

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

               (iv) In case the Parent shall, by dividend or otherwise,
         distribute to all or substantially all holders of its Common Stock
         evidences of its indebtedness, shares of any class of capital stock or
         other property (including cash or assets or securities, but excluding
         (A) any rights, options or warrants referred to in Section 6.3(c)(ii)
          -
         and any other rights, options or warrants that by their terms will also
         be issued to any Holder upon conversion of a Note into shares of Common
         Stock without any action required by the Parent or any other Person,
         (B) any dividend or distribution referred to in Section 6.3(c)(i) and
          -
         (C) mergers or consolidations to which Section 6.3(i) applies), the
          -
         Conversion Rate shall be adjusted so that the same shall equal the rate
         determined by dividing the Conversion Rate in effect immediately prior
         to the close of business on the date fixed for the determination of
         stockholders entitled to receive such distribution by a fraction of
         which (x) the numerator shall be the Current Market Price per share of
         the Common Stock on the date fixed for such determination less the then
         fair market value (as determined by the Board of Directors of the
         Parent) of the portion of the assets, shares or evidences of
         indebtedness so distributed applicable

                                       18



         to one share of Common Stock and (y) the denominator shall be such
                                           -
         Current Market Price per share of the Common Stock, such adjustment to
         become effective immediately prior to the opening of business on the
         day following the date fixed for the determination of stockholders
         entitled to receive such distribution. If after any such date fixed for
         determination, any such distribution is not in fact made, the
         Conversion Rate shall be immediately readjusted, effective as of the
         date the Board of Directors of the Parent determines not to make such
         distribution, to the Conversion Rate that would have been in effect if
         such determination date had not been fixed.

               (v) The reclassification of Common Stock into securities other
         than Common Stock (other than any reclassification upon a consolidation
         or merger to which Section 6.3(i) applies) shall be deemed to involve
         (A) a distribution of such securities other than Common Stock to all
          -
         holders of Common Stock (and the effective date of such
         reclassification shall be deemed to be "the date fixed for the
         determination of stockholders entitled to receive such distribution"
         and "the date fixed for such determination" within the meaning of
         Section 6.3(c)(iv)), and (B) a subdivision or combination, as the case
                                   -
         may be, of the number of shares of Common Stock outstanding immediately
         prior to such reclassification into the number of shares of Common
         Stock outstanding immediately thereafter (and the effective date of
         such reclassification shall be deemed to be "the day upon which such
         subdivision becomes effective" or "the day upon which such combination
         becomes effective," as the case may be, and "the day upon which such
         subdivision or combination becomes effective" within the meaning of
         Section 6.3(c)(iii).

               (vi) In the case the Parent shall issue or sell any shares of New
         Common Stock for consideration per share (such price per share, the
         "New Issue Price") less than either (A) the Current Market Price per
          ---------------                     -
         share of Common Stock or (B) the Conversion Price in effect on the date
                                   -
         of and immediately prior to such issuance, then and in such event, the
         Conversion Rate shall be increased by dividing such Conversion Rate by
         a fraction of which (x) the numerator shall be the number of shares of
                              -
         Common Stock outstanding immediately prior to such issuance or sale
         plus the number of shares of Common Stock which the aggregate of the
         purchase price of the total number of shares of Common Stock so issued
         or sold would purchase at (1) if the New Issue Price is less than both
                                    -
         such Current Market Price and such Conversion Price, the higher of such
         prices or (2) if the New Issue Price is less than either such Current
                    -
         Market Price or such Conversion Price but not both, such price that the
         New Issue Price is less than and (y) the denominator shall be the
                                           -
         number of shares of Common Stock outstanding immediately prior to such
         issuance or sale plus the number of shares of Common Stock so issued or
         sold, such increase to become effective immediately after the
         consummation of such issuance or sale.

                                       19



               (vii)  For purposes of this Agreement, the term "`ex' date," when
         used with respect to any issuance or distribution, means the first date
         on which the Common Stock trades the regular way in the applicable
         securities market or on the applicable securities exchange without the
         right to receive such issuance or distribution.

               (viii) The Parent may make such increases in the Conversion Rate,
         for the remaining term of the Notes or any shorter term, in addition to
         those required by paragraphs (i), (ii), (iii), (iv), (v), and (vi) of
         this Section 6.3(c), as it considers to be advisable in order to avoid
         or diminish any income tax to any holders of shares of Common Stock
         resulting from any dividend or distribution of stock or issuance of
         rights or warrants to purchase or subscribe for stock or from any event
         treated as such for income tax purposes. The Parent shall have the
         power to resolve any ambiguity or correct any error in this paragraph
         (viii) and its actions in so doing shall, absent manifest error, be
         final and conclusive.

               (ix)   Notwithstanding the provisions of Section 6.3(c)(iv), in
         the event that the then fair market value (as so determined) of the
         portion of the shares of capital stock, evidences of indebtedness, cash
         or other assets, including securities so distributed applicable to one
         share of Common Stock is equal to or greater than the Current Market
         Price per share of the Common Stock, then, in lieu of the adjustments
         provided for by Section 6.3(c)(iv), as the case may be, adequate
         provision shall be made so that each Holder shall have the right to
         receive upon conversion of a Note (or any portion thereof) the amount
         of shares of capital stock, evidences of indebtedness, cash or other
         assets, including securities, such Holder would have received had such
         Holder converted such Note (or portion thereof) immediately prior to
         the date fixed for such determination.

               (d)    Notice of Adjustments of Conversion Rate. Whenever the
                      ----------------------------------------
Conversion Rate is adjusted as herein provided the Parent shall compute the
adjusted Conversion Rate in accordance with Section 6.3(c) and shall prepare a
certificate signed by a Responsible Officer setting forth the adjusted
Conversion Rate and showing in reasonable detail the facts upon which such
adjustment is based, and such certificate shall promptly be provided to the
Holder.

               (e)    Notice of Certain Corporate Action. In case:
                      ----------------------------------

               (i)    the Parent shall declare a dividend (or any other
         distribution) on its Common Stock; or

               (ii)   the Parent shall authorize the granting to all or
         substantially all of the holders of its Common Stock of, or otherwise
         authorize the issuance to any

                                       20



         other Person, rights, options or warrants to subscribe for or purchase
         any shares of capital stock of any class or of any other rights; or

               (iii) the Parent shall subdivide the outstanding shares of Common
         Stock into a greater number of shares; or

               (iv)  the Parent shall distribute, by dividend or otherwise, to
         all or substantially all of the holders of Common Stock evidences of
         its indebtedness, shares of any class of capital stock or other
         property (including, without limitation, cash, assets or securities),
         subject to the exceptions set forth on Section 6.3(c)(iv); or

               (v)   of any reclassification of the Common Stock, or of any
         consolidation, merger or share exchange to which the Parent is a party
         and for which approval of any stockholders of the Parent is required,
         or of the conveyance, sale, transfer or lease of all or substantially
         all of the assets of the Parent; or

               (vi)  of the voluntary or involuntary dissolution, liquidation or

the date on which a record is to be taken for the purpose of such dividend,
distribution, rights, options or warrants, or, if a record is not to be taken,

such dividend, distribution, rights, options or warrants are to be determined or
(y) the date on which such reclassification, consolidation, merger, conveyance,
transfer, sale, lease, dissolution, liquidation or winding up is expected to
become effective, and the date as of which it is expected that holders of Common
Stock of record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, conveyance, transfer, sale, lease, dissolution,
liquidation or winding up. Neither the failure to give such notice or the notice
referred to in the next sentence nor any defect therein shall affect the
legality or validity of the proceedings described in clauses (i) through (vi) of
this Section 6.3(e). The Parent shall provide to all Holders notice of any
tender offer by the Company or any of its Subsidiaries for all or any portion of
the Common Stock at or about the time that such notice of tender offer is
provided to the public generally.

               (f)   Company to Reserve Common Stock. The Parent shall at all
                     -------------------------------
times reserve and keep available, free from preemptive rights, out of its

               (g)   Taxes on Conversions. Except as provided in the next
                     --------------------
sentence, the Parent will pay any and all taxes and duties that may be payable
in respect of the issue or delivery of shares of Common Stock on conversion of
Notes pursuant hereto. The Parent shall not, however, be required to pay any tax
or duty which may be payable in respect of any transfer involved in the issue
and delivery of shares of Common Stock in a name other than that of the Holder
of the Note or Notes to be converted, and no such issue or delivery shall be
made unless and until the Person requesting such issue has paid to the Parent
the amount of any such tax or duty, or has established to the satisfaction of
the Parent that such tax or duty has been paid.

               (h)   Covenants as to Common Stock and Distribution in Respect
                     --------------------------------------------------------
Thereof.
- -------

               (i)   The Parent agrees that all shares of Common Stock that may
     be delivered upon conversion of Notes, upon such delivery, will have been
     duly authorized and validly issued and will be fully paid and nonassessable
     and, except as provided in Section 6.3(g), the Parent will pay all taxes,
     liens and charges with respect to the issue thereof.

               (ii)  The Parent will not pay any dividend or make any
     distribution on shares of Common Stock held in the treasury of the Parent.

               (iii) The Parent will not issue any rights, options or warrants
     in respect of shares of Common Stock held in the treasury of the Parent.

               (i)   Provision in Case of Consolidation, Merger or Sale of
                     -----------------------------------------------------
Assets. In case of any consolidation or merger of the Parent with or into any
- ------
other Person or any merger of another Person with or into the Parent (in either
case, other than a merger which does not result in any reclassification,
conversion, exchange or cancellation of outstanding shares of Common Stock of
the Parent) or any conveyance, sale, transfer or lease of all or substantially
all of the assets of the Parent, the Person formed by such consolidation or
resulting from such merger or which acquires such assets, as the case may be,
shall execute and deliver to each Holder an agreement providing that the Holder
of each Note then outstanding shall have the right thereafter, during the period
such Note shall be convertible as specified in this Section 6.3, to convert such
Note only into the kind and amount of securities, cash and other property
receivable upon such consolidation, merger, conveyance, sale, transfer or lease
by a holder of the number of shares of Common Stock of the Parent into which
such Note might have been converted immediately prior to such consolidation,
merger, conveyance, sale, transfer or lease, assuming such holder of Common
Stock (x) is not (A) a Person with which the Parent
       -          -

                                       22



consolidated or merged with or into or which merged into or with the Parent or
to which such conveyance, sale, transfer or lease was made, as the case may be
(a "Constituent Person"), or (B) an Affiliate of a Constituent Person and (y)

failed to exercise his or her rights of election, if any, as to the kind or
amount of securities, cash and other property receivable upon such
consolidation, merger, conveyance, sale, transfer or lease (provided that if the
kind or amount of securities, cash and other property receivable upon such
consolidation, merger, conveyance, sale, transfer, or lease is not the same for
each share of Common Stock held immediately prior to such consolidation, merger,
conveyance, sale, transfer or lease by others than a Constituent Person or an
Affiliate thereof and in respect of which such rights of election shall not have
been exercised ("Non-electing Share"), then for the purpose of this Section
                 ------------------
6.3(i) the kind and amount of securities, cash and other property receivable
upon such consolidation, merger, conveyance, sale, transfer or lease by the
holders of each Non-electing Share shall be deemed to be the kind and amount so
receivable per share by a plurality of the Non-electing Shares). Such agreement
shall provide for adjustments which, for events subsequent to the effective date
of such agreement, shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section 6.3. The above provisions of this
Section 6.3(i) shall similarly apply to successive consolidations, mergers,
conveyances, sales, transfers or leases.

               (j)   Rights Issued in Respect of Common Stock. Rights, options
                     ----------------------------------------
or warrants distributed by the Parent to all holders of Common Stock entitling
the holders thereof to subscribe for or purchase shares of the Parent's capital
stock (either initially or under certain circumstances), which rights or
warrants, until the occurrence of a specified event or events (each, a "Trigger
                                                                        -------

Stock,

               (ii)  are not exercisable, and

               (iii) are also issued in respect of future issuances of Common
Stock

shall not be deemed distributed for purposes of this Section 6.3 until the
occurrence of the earliest Trigger Event. In addition, in the event of any
distribution of rights or warrants, or any Trigger Event with respect thereto,
that shall have resulted in an adjustment to the Conversion Rate under this
Section 6.3, (A) in the case of any such rights or warrants which shall all have
              -
been redeemed or repurchased without exercise by any holders thereof, the
Conversion Rate shall be readjusted upon such final redemption or repurchase to
give effect to such distribution or Trigger Event, as the case may be, as though
it were a cash distribution, equal to the per share redemption or repurchase
price received by a holder of Common Stock with respect to such rights or
warrants (assuming such holder had retained such rights or warrants), made to
all holders of Common Stock as of the date of such redemption or repurchase, and
(B) in the case of any such rights or
 -

                                       23



warrants all of which shall have expired without exercise by any holder thereof,
the Conversion Rate shall be readjusted as if such issuance had not occurred.

               (k)   Conversion Rights Subject to Stockholder Vote. If, pursuant
to any Requirement of Law or rule or regulation of any securities exchange or
national securities quotation service, the stockholders of the Parent are
required to approve the issuance of shares of Common Stock issuable upon
conversion of the Notes under this Agreement, no Note may be converted until
such issuance upon conversion has been so approved at the next annual meeting of
the Parent's stockholders following the Closing Date or otherwise. At any time
prior to such approval, upon the written request of Holders of Notes holding, at
any time, eighty percent (80%) of the aggregate Principal Amount of the Notes
outstanding at such time, the Parent, at its own expense and as soon as
practicable following such request, shall obtain the written consent of its
stockholders to such issuance upon conversion of the Notes, prepare and file
with the SEC an information statement relating to such stockholder approval and
take all other actions as are necessary or advisable under any Requirement of
Law or otherwise in respect of the issuance of Common Stock upon conversion of
the Notes.

Redemption") the Notes at any time, in whole or in part, without penalty or
- ----------
premium, in a minimum aggregate Principal Amount of $1,000,000 (or, if the
aggregate outstanding principal amount of the Notes is less than $1,000,000 at
such time, then such Principal Amount) and in integral multiples of $1,000,000,
in each case for a redemption price equal to the aggregate Principal Amount of
the Notes so redeemed, together with accrued but unpaid interest on such
Principal Amount to the date of redemption (the "Redemption Date"), without
                                                 ---------------
penalty or premium.

               (b)   If the Company undertakes an Optional Redemption in
accordance with this Section 6.4, notice (a "Redemption Notice") shall be given
                                             -----------------
by the Company, at its own expense, to each Holder of Notes to be redeemed. The
Redemption Notice shall be sent by first class mail, postage prepaid, to such
Holder's address appearing in the Note Register, by the Company not less than
thirty (30) nor more than sixty (60) days prior to the expected Redemption Date.
The Redemption Notice shall state:

               (i)   the expected Redemption Date;

     Principal Amount plus accrued but unpaid interest thereon, the "Redemption

     -----

          (iv) the place where or manner in which the Notes to be redeemed are
     to be surrendered to the Company for payment; and

          (c)  In the case of any partial Optional Redemption, selection of the
Notes for redemption will be made not more than sixty (60) days prior to the
Redemption Date by the Company on a pro rata basis, by lot or by such other
                                    --- ----
method as the Company in its sole discretion shall deem to be fair and
appropriate, although no Note of $1,000 in Principal Amount or less will be
redeemed in part.

          (d)  If a Redemption Notice has been given in accordance with this
Section 6.4, such Notes (or the portions thereof to be redeemed) shall, on the
Redemption Date, become due and payable at the Redemption Price and from and
after such date (unless the Company defaults in the payment of the Redemption
Price) such Notes (or the portions thereof to be redeemed) shall cease to bear
interest. Upon surrender of such Notes for redemption in accordance with such
Redemption Notice, such Notes (or the portions thereof to be redeemed) shall be
paid by the Company at the Redemption Price. If any Note (or portion thereof)
called for redemption shall not be so paid upon surrender thereof for
redemption, such Note shall, until paid, bear interest from the Redemption Date
at the Interest Rate.

          (e)  If any Note is duly surrendered by its Holder for redemption only
in part, following the consummation of such redemption, the Company shall
execute and deliver to such Holder, without service charge, a new Note or Notes,
of any authorized denomination as requested by such Holder, in aggregate
principal amount equal to and in exchange for the unredeemed portion of the
Principal Amount of the Note so surrendered.

     6.5  Mandatory Offer to Repurchase Upon Change of Control.
          ----------------------------------------------------

          (a)  In the event of the obtaining of actual knowledge of a Change of

          (b)  In the event of a Change of Control, the Company will, within

any action of the Company, at least thirty (30) days prior to such Change of
Control), give notice of such Change of Control to each Holder of Notes. Such
notice shall contain an irrevocable

                                       25

less than all, of the Notes held by such Holder, in each case for a purchase

     fulfilled; and

          (vii) state that a failure to respond to the notice shall be deemed to
     be an acceptance of such offer.

If the Company shall not have received a written response to such notice from
any Holder of Notes within ten (10) days after the date of posting of such
notice to such Holder of Notes, then the Company shall immediately send a second
notice to each such Holder of Notes.

          (c)   In the event that the Company makes a repurchase offer to the

shall (i) repay in full all such Bank Indebtedness (if otherwise permitted
       -
hereby) or (ii) if no other action is required by the terms of such Bank
            --
Indebtedness, offer to repay in full all such Bank Indebtedness and repay the
Bank Indebtedness of each holder thereof who has accepted such offer or (ii)
                                                                         --

(i) cause a notice of such acceptance to be delivered to the Company not later
than thirty (30) days after the date of receipt by such Holder of the written
offer of such repurchase or (ii) unless such Holder subsequently delivers a
                             --

offer of repurchase within such period of thirty (30) days. To reject such offer
such Holder of Notes shall deliver a written notice of rejection of such offer.
If accepted, such offered repurchase shall be due and payable on the Change of

          (e) The obligation of the Company to purchase Notes pursuant to the
offers required by Section 6.5(b) and accepted in accordance with Section 6.5(d)
is subject to the occurrence of the Change of Control in respect of which such
offers and acceptances shall have been made. In the event that such Change of
Control does not occur prior to the Change of Control Payment Date in respect
thereof, such purchase shall be deferred until and shall be made on the date on
which such Change of Control occurs or, if the Company determines that efforts
to effect such Change of Control have ceased or have been abandoned, then such
offer, acceptances and obligation to purchase shall be deemed to have been
rescinded. The Company shall keep each Holder of Notes reasonably and timely
informed of (i) any such deferral of the date of purchase; (ii) the date on
             -                                              --

                                                                          ---

or regulations in connection with the repurchase of Notes pursuant to this
Section 6.5. To the extent that the provisions of any securities laws or

comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under this Section 6.5 by virtue
thereof.

that, in any case, such noncompliance, and any other such noncompliance with any

permitted by Section 8.1(b)(iv)) or, as the case may be, the Company or its
Subsidiary determines not to proceed with such financing or refinancing. In
connection with any such grant to the Secured Parties of a Lien of record on any
such real property in accordance with this Section 7.9(a), the Company or such
Subsidiary shall deliver or cause to be delivered to the Secured Parties any
surveys, title insurance policies, environmental reports and other documents in

the cost and availability of such surveys, title insurance policies,
environmental reports and other documents and whether the delivery of such
surveys, title insurance policies, environmental reports and other documents
would be customary in connection with such grant of such Lien in similar
circumstances).

          (b) With respect to any Person that, subsequent to the date hereof,
becomes a Domestic Subsidiary or Foreign Subsidiary Holdco (other than to the
extent that compliance with this Section 7.9(b) would have an adverse tax

     and Collateral Agreement) deliver to the Secured Parties the certificates
     (if any) representing such Capital Stock, together with undated stock
     powers executed and delivered in blank by a duly authorized officer of the

     the Guarantee and Collateral Agreement, in each case pursuant to
     documentation which is in form and substance reasonably satisfactory to the
     Secured Parties, and (B) to take all actions reasonably deemed by any

the Guarantee and Collateral Agreement as any Secured Party shall reasonably
deem necessary or reasonably advisable to grant to the Secured Parties a Lien on

requested by any Secured Party, one or more other Note Security Documents in
form and substance reasonably satisfactory to the Secured Parties and
substantially equivalent to one or more security documents in respect of such
Bank Indebtedness), which Lien securing the CD&R Notes shall be on terms no less
favorable to the Holders thereof than the terms of such Lien securing such Bank
Indebtedness shall be to the holders of such Bank Indebtedness (it being
understood that such Lien securing the CD&R Notes shall be subject to the
Intercreditor Agreement).

     7.11 Note Guarantors.
          ---------------

Significant Subsidiary Guarantor will automatically and unconditionally be
released from all obligations under its Springing Guarantee, and such Springing
Guarantee shall thereupon terminate and be discharged and of no further force or
effect, (i) concurrently with any sale or disposition (by merger or otherwise)
         -

Guarantor or any interest therein by the Company or a Restricted Subsidiary,
following which such Significant Subsidiary Guarantor is no longer a Restricted
Subsidiary of the Company for the purposes of this Agreement and with respect to
the Notes, (ii) pursuant to the terms of its Springing Guarantee, (iii) at any
            --                                                     ---
time that such Significant Subsidiary Guarantor is released from all of its
obligations under all of its Springing Guarantees of payment of Indebtedness

Obligations in respect of Transferred Notes then due and owing. Upon any such
occurrence specified in the preceding sentence, each Holder of Transferred Notes
shall execute any documents reasonably required in order to evidence such
release, discharge and termination of such Significant Subsidiary Guarantee (at
the expense of the Company).

such Incurrence. The principal amount of any Indebtedness Incurred to refinance
other Indebtedness, if Incurred in a different currency from the Indebtedness
being refinanced, shall be calculated based on the currency exchange rate
applicable to the currencies in

                                       47



which such respective Indebtedness is denominated that is in effect on the date
of such refinancing.

in right of payment to any other Indebtedness of the Company, unless such
Indebtedness so Incurred is subordinated in right of payment to the Notes on
terms no less favorable to the Holders than the terms on which it is
subordinated to such other Indebtedness. No Note Guarantor shall Incur any
Indebtedness that is subordinated in right of payment to any other Indebtedness
of such Note Guarantor, unless such Indebtedness so Incurred is subordinated in

     10.2 Acceleration of Maturity; Rescission and Annulment.
          --------------------------------------------------

          (a)  If an Event of Default (other than an Event of Default specified
in clauses 10.1(h) through (l) with respect to the Company) occurs and is
continuing, the Holders of at least a twenty five percent (25%) of the aggregate
Principal Amount of the

                                       65



outstanding Notes, by notice to the Company specifying the respective Event of
Default and that such notice is a "Notice of Acceleration," may declare the
principal of and accrued but unpaid interest on all the Notes to be due and
payable. Upon such declaration, such principal and interest will be due and
payable immediately.

          (b)   Notwithstanding subsection (a) of this Section 10.2, if an Event
of Default specified in clauses 10.1(h) through (l) with respect to the Company
occurs and is continuing, then the principal of and any accrued interest on the
outstanding Notes will ipso facto become and be immediately due and payable
                       ---- -----
without any declaration or other act on the part of any Holder.

          (c)   The Holders of a majority in aggregate Principal Amount of the
outstanding Notes may, by notice to the Company, 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. No such
rescission shall affect any subsequent Default or impair any right consequent
thereto.

          10.3  Unconditional Right of Holders to Receive Principal, Premium and
                ----------------------------------------------------------------
Interest. Notwithstanding any other provision of this Agreement or any other

of and all interest on the Note or Notes held by it on the Interest Payment
Dates and Stated Maturity expressed in such Note or Notes, and to institute suit
for the enforcement of any such payment on or after such Interest Payment Dates
and Stated Maturity, shall not be impaired without the consent of such Holder.

          10.4  Restoration of Rights and Remedies. If any Holder has instituted
                ----------------------------------
any proceeding to enforce any right or remedy under this Agreement and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to such Holder, then and in every such case the Company,
any other obligor upon the Notes and the Holders shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Holders shall continue as though no such proceeding had been instituted.

          10.5  Rights and Remedies Cumulative. No right or remedy herein
                ------------------------------
conferred upon the Holders is 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.

          10.6  Delay or Omission Not Waiver. No delay or omission of any Holder
                ----------------------------
to exercise any right or remedy accruing upon any Event of Default shall impair
any such

                                       66



right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article X or by law
to the Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Holders.

          10.7  Waiver of Past Defaults. The Holders of not less than a majority
                -----------------------
in aggregate Principal Amount of the outstanding Notes may, on behalf of the
Holders of all of the Notes, waive any past Default hereunder and its
consequences, except a Default in the payment of the principal of or interest on
any Note (which may only be waived with the consent of each Holder of Notes
directly affected), and except as may otherwise be provided in Section 13.7.
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose,
but no such waiver shall extend to any subsequent or other Default or Event of
Default or impair any right consequent thereon. In case of any such waiver, the
Company, each Note Guarantor, any other obligor upon the Notes and the Holders

               (a)  if since the beginning of such period the Company or any

Indebtedness after such Sale;

          (d)  if since the beginning of such period the Company or any
Restricted Subsidiary (by merger, consolidation or otherwise) shall have made an
Investment in any Person that thereby becomes a Restricted Subsidiary, or
otherwise acquired any company, any business or any group of assets constituting
an operating unit of a business, including any such Investment or acquisition
occurring in connection with a transaction causing a calculation to be made
hereunder (any such Investment or acquisition, a "Purchase"), Consolidated

Restricted Subsidiary or was merged or consolidated with or into the Company or
any Restricted Subsidiary, and since the beginning of such period such Person

have required an adjustment pursuant to clause (b), (c) or (d) above if made by

Sale, Purchase or other transaction, or the amount of income or earnings
relating thereto and the amount of Consolidated Interest Expense associated with

calculations in respect thereof (including without limitation in respect of
anticipated cost savings or synergies relating to any such Sale, Purchase or
other transaction) shall be as determined in good faith by a responsible
financial or accounting officer of the Company. If any Indebtedness bears a
floating rate of interest and is being given pro forma effect, the interest
expense on such Indebtedness shall be calculated as if the rate in effect on the
date of determination had been the applicable rate for the entire period (taking
into account any Interest Rate Agreement applicable to such Indebtedness). If
any Indebtedness bears, at the option of the Company or a Restricted Subsidiary,
a rate of interest based on a prime or similar rate, a eurocurrency interbank
offered rate or other fixed or floating rate, and such Indebtedness is being
given pro forma effect, the interest expense on such Indebtedness shall be
calculated by applying such optional rate as the Company or such Restricted
Subsidiary may designate. If any Indebtedness that is being given pro forma
effect was Incurred

                                       73



under a revolving credit facility, the interest expense on such Indebtedness
shall be computed based upon the average daily balance of such Indebtedness
during the applicable period. Interest on a Capitalized Lease Obligation shall
be deemed to accrue at an interest rate determined in good faith by a
responsible financial or accounting officer of the Company to be the rate of
interest implicit in such Capitalized Lease Obligation in accordance with GAAP.

misconduct of such Holder (or any of its respective directors, trustees,
officers, employees, agents, successors and assigns) or (B) claims made or legal
                                                         -
proceedings commenced against such Holder by any securityholder or creditor
thereof arising out of

                                      105



and based upon rights afforded any such securityholder or creditor solely in its
capacity as such.

          (b) Notwithstanding the foregoing provisions of Section 13.9(a),
except as provided in clauses (ii) and (iii) of Section 13.9(a) and subject to
the provisions of this Section 13.9(b), the Company shall have no obligation
under Section 13.9(a) to any Holder with respect to any withholding or deduction
required by any Governmental Authority to be made by the Company from any
payment by the Company to such Holder of principal of or interest on any Note,
for or on account of any tax, levy, impost or duty, or any charge or fee in the
nature of a tax, levy, impost or duty, that is imposed, levied, collected or
assessed by such Governmental Authority (a "withholding tax"). If any payment of
                                            ---------------
withholding tax shall be required by any Governmental Authority to be made by
the Company from any payment of principal of or interest on any Note, the
Company shall give notice thereof to the Holder of such Note no later than 15
Business Days prior to such payment. If any payment of withholding tax shall be
required by any Governmental Authority to be made by the Company from any
payment of principal of or interest on any Note in cash, a portion of such
payment of principal or interest equal to the amount of such withholding tax
paid to such Governmental Authority shall be deemed to have been paid to the
Holder of such Note for all purposes of this Agreement. If any payment of
withholding tax shall be required by any Governmental Authority to be made by
the Company from any payment of interest on any Note through the issuance of an
additional Note as provided in Section 6.2(a), the Company shall withhold and
reduce the face value of such additional Note by an amount equal to the amount
of such withholding tax paid to such Governmental Authority, and a portion of
such payment of interest equal to the amount of face value so withheld and
reduced shall be deemed to have been paid to the Holder of such Note for all
purposes of this Agreement, provided that the Parent shall, upon such
withholding and reduction of face amount, issue and deliver Warrants to the
Holder of such Note that entitle such Holder to purchase a number of shares of
Common Stock (or other property) that shall fairly compensate such Holder for
the loss of the conversion rights pursuant to Section 6.3 with respect to the
face amount of such additional Note so withheld and reduced, and with respect to
the face amount of any additional Notes that would have been issued in respect
of interest on any such additional Note if the face amount thereof had not been
so withheld and reduced, the provisions of such Warrants and the issuance and
delivery thereof to be effected as provided in Section 6.7, with such changes as
may be necessary or appropriate under the circumstances. The Company and the
relevant Holder shall use their respective good faith efforts to agree on the
number of such shares of Common Stock (or other property) and the provisions of
such Warrants. The Company and the relevant Holder shall use their respective
good faith efforts to avoid or minimize the payment of withholding tax from any
payment of principal of or interest on the Notes, provided that such Holder
shall not be required to (x) change its place of organization or any office or
                          -
other place of business thereof or (y) take other any action or refrain from
                                    -
taking any action, which action or inaction, in its reasonable judgment, would
be significantly disadvantageous to

                                      106



its business or operations or would require it to incur additional costs. Such
efforts shall include but not be limited to such Holder's provision of all
applicable withholding certificates, compliance certificates and representations
relating to status, subject to the proviso to the preceding sentence. Nothing in
this Section 13.9(b) shall be construed to require any Holder to disclose any of
such Holder's books, records or tax filings to the Company or any other party.

           (c) The agreements in this Section 13.9 shall survive repayment of
the Notes and all other amounts payable hereunder and the issuance of the
Warrants.

     13.10 Judgment Currency.
           -----------------

           (a) If for the purpose of obtaining judgment in any court it is
necessary to convert a sum due hereunder in one currency into another currency,
the parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which in accordance with normal
banking procedures each Holder could purchase the first currency with such other
currency in the City of New York, New York for the first currency on the
Business Day preceding the day on which final judgment is given.

           (b) The obligation of the Company in respect of any sum due from it
to any Holder hereunder shall, notwithstanding any judgment in a currency (the
"Judgment Currency") other than that in which such sum is denominated in

accordance with the applicable provisions of this Agreement (the "Agreement
                                                                  ---------
Currency"), be discharged only to the extent that on the Business Day following
- --------
receipt by such Holder of any sum adjudged to be so due in the Judgment Currency
such Holder may in accordance with normal banking procedures purchase the
Agreement Currency with the Judgment Currency; if the amount of Agreement
Currency so purchased is less than the sum originally due to such Holder in the
Agreement Currency, the Company agrees notwithstanding any such judgment to
indemnify such Holder against such loss, and if the amount of the Agreement
Currency so purchased exceeds the sum originally due to any Holder, such Holder
agrees to remit to the Company such excess.

maximum extent possible. In any event, the invalidity or unenforceability of any
provision of this Agreement in any jurisdiction shall not affect the validity or
enforceability of the remainder of this Agreement in that

                  Terms of Note Guarantees of Transferred Notes

     1.   Guarantees Generally.
          --------------------

     (a) Parent Guarantee. Parent, as a primary obligor and not merely as
         ----------------
surety, hereby irrevocably and fully and unconditionally Guarantees, on a senior
basis, the punctual payment when due, whether at the Maturity Date, by
acceleration or otherwise, of all monetary obligations of the Company under the
Agreement and the Transferred Notes, whether for principal of or interest on the
Transferred Notes, expenses, indemnification or otherwise (all such obligations
guaranteed by Parent being herein called the "Parent Guaranteed Obligations").
                                              -----------------------------

     (b) Note Guarantees. Any Significant Subsidiary Guarantor from time to time
         ---------------
party hereto, as primary obligor and not merely as surety, hereby jointly and
severally, irrevocably and fully and unconditionally Guarantees, on a senior
basis, the punctual payment when due, whether at the Maturity Date, by
acceleration or otherwise, of all monetary obligations of the Company under the
Agreement and the Transferred Notes, whether for principal of or interest on the
Transferred Notes, expenses, indemnification or otherwise (all such obligations
guaranteed by such Significant Subsidiary Guarantors being herein called the
"Springing Guaranteed Obligations").
 --------------------------------

     Any term or provision of the Agreement notwithstanding, each Springing
Guarantee shall not exceed the maximum amount that can be guaranteed by the
applicable Significant Subsidiary Guarantor without rendering the Springing
Guarantee, as it relates to such Significant Subsidiary Guarantor, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.

     (c) Further Agreements of Parent Guarantor and any Significant Subsidiary
         ---------------------------------------------------------------------
Guarantor. (i) Parent, in its capacity as guarantor of the Parent Guaranteed
- ---------
Obligations hereunder (in such capacity, the "Parent Guarantor") and any
                                              ----------------
Significant Subsidiary Guarantor from time to time party hereto (each of the
Parent Guarantor and any Significant Subsidiary Guarantor, a "Guarantor") each
                                                              ---------
hereby agrees that (to the fullest extent permitted by law) its obligations
hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Agreement, the Transferred Notes or the obligations of the
Company or any other Guarantor to the Holders of the Transferred Notes hereunder
or thereunder, the absence of any action to enforce the same, any waiver or
consent by any Holder of Transferred Notes with respect to any provisions hereof
or thereof, any release of any other Guarantor, the recovery of any judgment
against the Company, any action to enforce the same, whether or not a notation
concerning its respective Parent Guarantee or Springing Guarantee is made on any
particular Transferred Note, or any other circumstance that might otherwise
constitute a legal or equitable discharge or defense of a guarantor.



     (ii) Each Guarantor hereby waives (to the fullest extent permitted by law)
the benefit of diligence, presentment, demand of payment, filing of claims with
a court in the event of insolvency or bankruptcy of the Company, any right to
require a proceeding first against the Company, protest, notice and all demands
whatsoever and covenants that its Parent Guarantee or (except as otherwise
provided in Section 7.11(b) of the Agreement) Springing Guarantee, as the case
may be, will not be discharged except by complete performance of the obligations
contained in the Transferred Notes, the Agreement, and its Parent Guarantee or
Springing Guarantee, as the case may be. Such Parent Guarantee or Springing
Guarantee, as the case may be, is a guarantee of payment and not of collection.
Each Guarantor further agrees (to the fullest extent permitted by law) that, as
between it, on the one hand, and the Holders of the Transferred Notes, on the
other hand, subject to the provisions of this Annex A, (1) the maturity of the
                                                        -
obligations guaranteed by its Parent Guarantee or Springing Guarantee, as the
case may be, may be accelerated as and to the extent provided in Article X of
the Agreement for the purposes of such Parent Guarantee or Springing Guarantee,
as the case may be, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed by such
Parent Guarantee or Springing Guarantee, as the case may be, and (2) in the
                                                                  -
event of any acceleration of such obligations as provided in Article X of the
Agreement, such obligations (whether or not due and payable) shall forthwith
become due and payable by such Guarantor in accordance with the terms of the
provisions of this Annex A for the purpose of such Parent Guarantee or Springing
Guarantee, as the case may be. No Holder of Transferred Notes shall have any
obligation to enforce or exhaust any rights or remedies or to take any other
steps under any security for the Parent Guaranteed Obligations or the Springing
Guaranteed Obligations (collectively, the "Guaranteed Note Obligations") or
                                           ---------------------------
against the Company or any other Person or any property of the Company or any
other Person before the Holder of Transferred Notes is entitled to demand
payment and performance by any or all Guarantors of their obligations under
their respective Parent Guarantee or Significant Guarantees or under the
Agreement.

     (iii) The Parent Guarantee and, unless and until terminated in accordance
with Section 7.11(b) of the Agreement, any Springing Guarantee, shall remain in
full force and effect and continue to be effective should any petition be filed
by or against the Company for liquidation or reorganization, should the Company
become insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any significant part of the
Company's assets, and shall, to the fullest extent permitted by law, continue to
be effective or be reinstated, as the case may be, if at any time payment and
performance of the Transferred Notes are, pursuant to applicable law, rescinded
or reduced in amount, or must otherwise be restored or returned by any obligee
on such Transferred Notes, whether as a "voidable preference," "fraudulent
transfer" or otherwise, all as though such payment or performance had not been
made. In the event that any payment, or any part thereof, is rescinded, reduced,
restored or returned, the

                                       A-2



Transferred Notes shall, to the fullest extent permitted by law, be reinstated
and deemed reduced only by such amount paid and not so rescinded, reduced,
restored or returned.

     (d) Each Guarantor that makes a payment or distribution under the Parent
Guarantee or any Springing Guarantee, as the case may be, shall have the right
to seek contribution from the Company or any non-paying Guarantor that has also
Guaranteed the Guaranteed Note Obligations in respect of which such payment or
distribution is made, so long as the exercise of such right does not impair the
rights of the Holders of the Transferred Notes under the Parent Guarantee or
such Springing Guarantee.

     (e) Each Guarantor acknowledges that it will receive direct and indirect
benefits from the financing arrangements contemplated by the Agreement and that
its Parent Guarantee or its Springing Guarantee, as the case may be, and the
waiver set forth in Section 3 of this Annex A is knowingly made in contemplation
of such benefits.

     (f) Each Guarantor also hereby agrees to pay any and all reasonable
out-of-pocket expenses (including reasonable counsel fees and expenses) incurred
by the Holders of Transferred Notes in enforcing any rights under its Parent
Guarantee or its Springing Guarantee, as the case may be.

     2.   Continuing Guarantees. (a) The Parent Guarantee shall be a continuing
          ---------------------
Guarantee and shall (i) remain in full force and effect until payment in full of
                     -
the Principal Amount of all outstanding Transferred Notes (whether by payment at
maturity, purchase, redemption, defeasance, retirement or other acquisition) and
all other Parent Guaranteed Obligations then due and owing, (ii) be binding upon
                                                             --
Parent and (iii) inure to the benefit of and be enforceable by the Holders of
            ---
Transferred Notes and their permitted successors, transferees and assigns.

     (b) Each Springing Guarantee shall be a continuing Guarantee and shall (i)
                                                                             -
remain in full force and effect until payment in full of the principal amount of
all outstanding Transferred Notes (whether by payment at maturity, purchase,
redemption, defeasance, retirement or other acquisition) and all other
Guaranteed Obligations then due and owing, unless earlier terminated as provided
in Section 7.11(b) of the Agreement, (ii) be binding upon such Guarantor and
                                      --
(iii) inure to the benefit of and be enforceable by the Holders of the
 ---
Transferred Notes and their permitted successors, transferees and assigns.

     3.   Waiver of Subrogation. Each of the Parent Guarantor and each
          ---------------------
Significant Subsidiary Guarantor hereby irrevocably waives any claim or other
rights that it may now or hereafter acquire against the Company that arise from
the existence, payment, performance or enforcement of the Company's obligations
under the Transferred Notes and the Agreement or such Guarantor's obligations
under its Parent Guarantee or Springing Guarantee, as the case may be, and the
Agreement, including, without

                                       A-3



limitation, any right of subrogation, reimbursement, exoneration,
indemnification, and any right to participate in any claim or remedy of any
Holder of Transferred Notes against the Company, whether or not such claim,
remedy or right arises in equity, or under contract, statute or common law,
until the Agreement is discharged and all of the Transferred Notes are
discharged and paid in full. If any amount shall be paid to a Guarantor in
violation of the preceding sentence and the Transferred Notes shall not have
been paid in full, such amount shall have been deemed to have been paid to such
Guarantor for the benefit of, and held in trust for the benefit of, the Holders
of the Transferred Notes, and shall forthwith be paid to the Holders of
Transferred Notes to be credited and applied upon the Transferred Notes, whether
matured or unmatured, in accordance with the terms of the Agreement and this
Annex A.

     4.   Notation Not Required. Neither the Company nor any Guarantor shall be
          ---------------------
required to make a notation on the Transferred Notes to reflect the Parent
Guarantee or any Springing Guarantee or any such release, termination or
discharge thereof.

     5.   Successors and Assigns of the Parent Guarantor and the Other
          ------------------------------------------------------------
Guarantors. All covenants and agreements in the Agreement or the terms of this
- ----------
Annex A by each Guarantor shall bind its respective successors and assigns,
whether so expressed or not.

     6.   Execution and Delivery of Note Guarantees. Concurrently with the
          -----------------------------------------
execution and delivery of the instrument required to be delivered under Section
7.11(b) of the Agreement, the Company shall deliver to the Holders of
Transferred Notes an opinion of counsel (which counsel shall be reasonably
satisfactory to the Majority Transferred Note Holders) in form and substance
reasonably satisfactory to the Majority Transferred Note Holders to the effect
that such instrument has been duly authorized, executed and delivered by the
relevant Significant Subsidiary Guarantor and that, subject to the applicable
bankruptcy, insolvency, fraudulent transfer, fraudulent conveyance,
reorganization, moratorium and other laws now or hereafter in effect affecting
creditors' rights or remedies generally and the general principles of equity
(including standards of materiality, good faith, fair dealing and
reasonableness), whether considered in a proceeding at law or at equity such
instrument is a valid and binding agreement of such Significant Subsidiary
Guarantor, enforceable against such Significant Subsidiary Guarantor in
accordance with its terms.
