     WHEREAS, the Parent, the Company and the Investor desire to enter into this
Agreement to govern the terms of the CD&R Barbados Investment;

     NOW, THEREFORE, in consideration of the mutual premises, covenants,
representations and warranties made in this Agreement and of the mutual benefits
to be derived from this Agreement, the parties hereto agree as follows:

                                    Article I
                  Grant of the Right; Authorization, Issuance,
                     Purchase and Sale of Notes and Warrants

     1.1 Grant and Acceptance. The Company hereby grants to the Investor the
right to invest in Initial Notes an amount equal to the Net Cash Interest Amount
in respect of any cash interest paid by the Company and received by the Investor
in respect of interest owing by the Company to the Investor on any Senior
Subordinated Note Interest Payment Date for so long as the Investor owns any
Senior Subordinated Notes (with respect to each such Senior Subordinated Note
Interest Payment Date, an "Investment Right"), and the Investor hereby accepts
such Investment Right.

     1.2 Authorization of the Notes. The Company has authorized the issuance and
sale of the Notes on the terms set forth in this Agreement, to be designated as
Series 2-A through Series 2-K, with the Notes issued following the first

                                        2

<PAGE>

its Investment Right to be designated as Series 2-A and the Notes issued
following each exercise by the Investor of its Investment Right thereafter to be
designated with the following letter of the alphabet through and including the
letter "K". Any additional Notes issued pursuant to Section 6.2(a)(ii) shall
have the same designation as the Notes with respect to which such additional
notes were issued. The Notes shall be in the form of Exhibit A hereto, with such
changes therefrom, if any, as may be approved by the Company and the Investor.

     1.3 Authorization of Warrants. The Parent has authorized the issuance, upon
the redemption or repurchase of the Notes prior to the Maturity Date, of
warrants (each, a "Warrant") to purchase a number of newly-issued shares of
Common Stock equal to the number of shares of Common Stock into which the Notes
were convertible immediately prior to such redemption or repurchase, at the
exercise price per share equal to the Conversion Price, to be in the form of
Exhibit B hereto, with such changes therefrom, if any, as may be approved by the
Parent and the Holder of the Notes so redeemed or repurchased.

     1.4 Sale and Purchase of Notes. An Investment Right with respect to any
Senior Subordinated Note Interest Payment Date may be exercised by the Investor

and ending on the fifth (5/th/) Business Day following, each Senior Subordinated
Note Interest Payment Date occurring after the date hereof (each, an "Exercise
Period"), by written notice to the Company and the Appraiser, which notice shall
state (a) that the Investor has elected to exercise such Investment Right and
(b) the amount equal to the Net Cash Interest Amount being invested in Initial
Notes pursuant to such notice (an "Election Notice"). Following receipt of such
Election Notice, and subject to the terms and conditions of this Agreement, at
each Closing the Company will issue and sell to the Investor, and the Investor
will purchase from the Company, Initial Notes for a purchase price and in an
aggregate Principal Amount equal to the Net Cash Interest Amount with respect to
such Senior Subordinated Note Interest Payment Date (the "Purchase Price"). The
Investor agrees that the Investment Right will be exercised if, and only to the
extent required by, the terms of the Third Credit Agreement Amendment or any
agreement contemplated thereby.

exercised with respect to a Senior Subordinated Note Interest Payment Date
falling on November 15 of any year, the later to occur of (i) the fifth (5/th/)
Business Day after the final determination of the Conversion

other Business Day thereafter as may be agreed upon by the Parent, the Company

"Closing Date").

     2.2 Delivery of Initial Notes and Purchase Price. At each Closing, (a) the
Company will deliver the Initial Notes to the Investor in the form of a single
promissory note (or such greater number of promissory notes in denominations of
at least $1,000 and integral multiples thereof as the Investor may request), in
the form of Exhibit A hereto, with such changes therefrom, if any, as may be
approved by the Company and the Investor, dated the Closing Date and registered

Securities and Exchange Commission (and reported on by and accompanied by an
unqualified report from the Parent's independent public accountant), 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 for the most recent quarterly reporting period, and the
related unaudited consolidated statements of income and cash flows for the
interim quarterly fiscal period ended on such date, as filed by the Parent with
the United States Securities and Exchange Commission, on the basis disclosed in
the footnotes to such financial statements, present fairly, in all material
respects, the consolidated financial condition of the Parent and its
Subsidiaries as at such date, and the consolidated results of its operations and
its consolidated cash flows for the interim quarterly fiscal period then ended
(subject to the omission of certain footnotes and normal year-end audit and
other adjustments). All such financial statements, including the related
schedules and notes 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.

     3.5 Absence of Changes. Since the date of the most recent report filed by
Parent with the United States Securities and Exchange Commission on Form 10-Q or
Form 10-K, there has been no development or event relating to or affecting the
Parent, the Company or any Subsidiary of the Company which has had or would
reasonably be expected to have a Material Adverse Effect (after giving effect to
the Transactions).

Requirement of Law or any Contractual Obligation applicable to or binding upon
the Parent, the Company and any Subsidiary of the Company or any of their
respective properties or assets in any respect that would reasonably be expected
to have a Material Adverse Effect and (b) will not result in the creation or

     3.7  No Material Litigation. No litigation by, investigation by, or
proceeding of or before any arbitrator or any Governmental Authority is pending
or, to the knowledge of the Parent, the Company or any Subsidiary of the

as currently conducted, except for those United States trademarks, tradenames,
copyrights, technology, know-how and processes, the failure to own or license

claim has been asserted and is pending by any Person

                                        7

challenging or questioning the use of any Intellectual Property or the validity
or effectiveness of any Intellectual Property, nor does the Parent, the Company
or any Subsidiary of the Company know of any valid basis for any such claim and
to the knowledge of each of the Parent, the Company and the Subsidiaries of the

reasonably be expected to have a Material Adverse Effect.

     3.11 No Burdensome Restrictions. No Requirement of Law applicable to or
Contractual Obligation of any of the Parent, the Company and the Subsidiaries of
the Company would reasonably be expected to have a Material Adverse Effect.

or caused to be filed all United States federal income tax returns and all other
material tax returns which, to the knowledge of the Company, are required to be
filed and has paid all taxes shown to be due and payable on said returns or on
any assessments made against it or any of its property and all other taxes, fees

Authority (other than any (i) taxes, fees or other charges with respect to which
the failure to pay, in the aggregate, would not have a Material Adverse Effect
or (ii) taxes, fees or other charges the amount or validity of which are
currently being contested in good faith by appropriate proceedings and with
respect to which reserves in conformity with GAAP have been provided on the
books of the Parent, the Company or its Subsidiaries, as the case may be); no

                      The Convertible Notes; General Terms

     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 Specified Interest Rate
(the "Interest Rate"), 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, 2003 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

                                       15

<PAGE>

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 from the relevant
Interest Payment Date at the Interest Rate equal to the Interest Rate applicable
to such Note, (D) having a face value equal to the amount of the Interest
Payment applicable to such Note, and (E) having the Conversion Rate equal to the
Conversion Rate 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.

          (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 of any particular Note (the "Conversion Rate") shall be the Specified
Conversion Rate for such Note. 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.

          (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

                                       17

<PAGE>

     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 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
     the Current Market Price per share of the Common Stock 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

                                       18

<PAGE>

     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 such Current Market Price and (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 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,

                                       19

<PAGE>

     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 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 (other than pursuant to securities referred to in Section
     6.3(c)(ii)) for consideration per share (such price per share, the "New
     Issue Price") less than

                                       20

<PAGE>

     the Current Market Price per share of Common Stock, 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 such Current Market Price 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.

          (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.

     Notwithstanding the foregoing, the issuance of Notes or Warrants pursuant
to this Agreement shall not cause any anti-dilution adjustments to be made to
any other Notes or Warrants previously issued pursuant to this Agreement.

                                       21

<PAGE>

          (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 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
     winding up of the Parent;

then the Parent shall provide to all Holders, at least twenty (20) days (or ten
(10) days in any case specified in clause (i) or (ii) above) prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
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,
the date as of which the holders of Common Stock of record to be entitled to
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

                                       22

<PAGE>

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 authorized
but unissued Common Stock (including treasury stock), for the purpose of
effecting the conversion of Notes, the full number of shares of Common Stock
then issuable upon the conversion of all then outstanding Notes.

          (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

                                       23

<PAGE>

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 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
Event"):

          (i)   are deemed to be transferred with such shares of Common Stock,

          (ii)  are not exercisable, and

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

                                       24

<PAGE>

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 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 seek the written consent or approval
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.

     6.4  Optional Redemption.

          (a)  The Company may, at its option, redeem (each, an "Optional
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

                                       25

<PAGE>

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;

          (ii)  that such redemption is an Optional Redemption made pursuant to
     this Section 6.4;

          (iii) the Principal Amount of each Note to be redeemed plus the amount
     of the interest to be paid on each such Note, accrued to the Redemption
     Date (the Principal Amount plus accrued but unpaid interest thereon, the
     "Redemption Price");

          (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
Control Notice Event, the Company will, within three (3) Business Days after the

                                       26

<PAGE>

occurrence of such event, give notice of such Change of Control Notice Event to
each Holder of Notes. Each such notice shall (i) be dated the date of the
sending of such notice; (ii) refer to this Section 6.5; and (iii) specify, in
reasonable detail, the nature and date of the Change of Control Notice Event.

          (b)   In the event of a Change of Control, the Company will, within
three (3) Business Days after the occurrence of such event (or, in the case of
any Change of Control the consummation or finalization of which would involve
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 separate offer by the Company to each Holder
of Notes to repurchase all, but not less than all, of the Notes held by such
Holder, in each case for a purchase price equal to the aggregate Principal
Amount of Notes so repurchased, together with accrued but unpaid interest on
such Principal Amount to the date of repurchase, without penalty or premium.
Such payment shall occur on a date (the "Change of Control Payment Date")
specified in such notice that is not less than thirty (30) days and not more
than forty-five (45) days after the date of such notice. Each such notice shall:

          (i)   be dated the date of the sending of such notice;

          (ii)  specify, in reasonable detail, the nature and date of the Change
     of Control;

          (iii) specify the Change of Control Payment Date;

          (iv)  specify the Principal Amount of each Note outstanding;

          (v)   specify the interest that will be due on each Note offered to be
     repurchased, accrued to the Change of Control Payment Date;

          (vi)  certify that the conditions of this Section 6.5 have been
     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
Holders of the Notes in accordance with subsection (b) of this Section 6.5, but
at the time such offer is made the terms of any Bank Indebtedness restrict or
prohibit such

                                       27

<PAGE>

repurchase of Notes, then prior to the mailing of a notice to Holders in
accordance with subsection (b) of this Section 6.5, but in any event not later
than thirty (30) days following the date of any Change of Control (unless the
Company has exercised its right to redeem all the Notes under Section 6.4 or has
repurchased all the Notes under Section 6.6), the Company 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 (iii) obtain the requisite consent
under the agreements governing such Bank Indebtedness to permit the repurchase
of Notes as provided for in this Section 6.5.

          (d)  To accept such repurchase offer, a Holder of Notes shall either
(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
written notice of rejection to the Company, fail to respond to such written
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
Control Payment Date.

          (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
which such Change of Control and the purchase are expected to occur; and (iii)
any determination by the Company that efforts to effect such Change of Control
have ceased or been abandoned.

          (f)  The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
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
regulations conflict with provisions of this Section 6.5, the Company will
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.

     6.6  Mandatory Offer to Repurchase CD&R Barbados Notes Upon Disposition of
Assets.

          (a)  For purposes of this Section 6.6(a), the term "Mandatory 6.6(a)
Repurchase Event" shall mean:

          (i)  any sale, transfer or other disposition by the Company or any of
     its Subsidiaries of any real or personal, tangible or intangible, property
     of the Company or such Subsidiary (including, without limitation, any
     Capital Stock of a Subsidiary of the Company) to any Person (other than to
     the Company or any of its Restricted Subsidiaries) that is either (x) not
     permitted under the Credit Agreement as in effect on the Closing Date
     (giving effect to the Third Credit Agreement Amendment) but has been
     consented to by the requisite lenders under the Credit Agreement, or (y) is
     permitted under, but is subject to any mandatory prepayment requirement of,
     the Credit Agreement, or

          (ii) the recovery by the Company or any of its Subsidiaries of amounts
     owing to it under property insurance policies if the Company and its
     Subsidiaries have not commenced replacement of the property on account of
     which such amounts were paid within one year of the later of the date of
     the casualty to, or condemnation of, such property or the receipt of such
     Net Proceeds.

If, on any date during the Adjustment Period, the Company or any of its
Subsidiaries shall receive Net Proceeds from any Mandatory 6.6(a) Repurchase
Event, the Company shall give notice thereof to the Investor and any other
member of the CD&R Group that is a Holder. Such notice shall contain an
irrevocable separate offer by the Company to repurchase each such Holder's CD&R
Barbados Notes on the applicable Mandatory Repurchase Date (subject to prorating
as described in Section 6.6(d)), for a purchase price equal to the Principal
Amount of Notes so repurchased (plus accrued and unpaid interest on the
Principal Amount thereof so repurchased to the date of repurchase). The
aggregate purchase price to be so applied to repurchase CD&R Barbados Notes
(excluding accrued and unpaid interest) shall be equal to (x) the aggregate
amount of such Net Proceeds not previously applied to permanently prepay Bank
Indebtedness under the Credit Agreement minus (y) the aggregate amount of such
Net Proceeds required to be applied to repurchase Fund VI Notes pursuant to
Section 6.6(a) of the Fund VI Investment Agreement minus (z) the Reinvested
Amount related thereto; provided, however, that in no event shall the aggregate
amount of all Reinvested Amounts subtracted from such Net Proceeds received in
connection with asset dispositions described in clause (i) of the definition of
"Mandatory 6.6(a) Repurchase Event" exceed $10,000,000 in any fiscal year of the
Company.

          (b)  For purposes of this Section 6.6(b), the term "Mandatory 6.6(b)
Repurchase Event" shall mean:

                                       29

<PAGE>

          (i)  the sale, transfer or other disposition by the Company or any of
     its Subsidiaries of any real or personal, tangible or intangible, property
     of the Company or such Subsidiary (including, without limitation, any
     Capital Stock of a Subsidiary of the Company) to any Person (other than to
     the Company or any of its Restricted Subsidiaries) that is either (x) not
     permitted under the Credit Agreement (as in effect prior to giving effect
     to the Second Credit Agreement Amendment) but has been consented to by the
     requisite lenders under the Credit Agreement, or (y) is permitted under,
     but is subject to any mandatory prepayment requirement of, the Credit
     Agreement, or

          (ii) the recovery by the Company or any of its Subsidiaries of amounts
     owing to it under property insurance policies if the Company and its
     Subsidiaries have not commenced replacement of the property on account of
     which such amounts were paid within one year of the later of the date of
     the casualty to, or condemnation of, such property or the receipt of such
     Net Proceeds.

If, on any date other than during the Adjustment Period, the Company or any of
its Subsidiaries shall receive Net Proceeds from any Mandatory 6.6(b) Repurchase
Event, the Company shall give notice thereof to the Investor and any other
member of the CD&R Group that is a Holder. Such notice shall contain an
irrevocable separate offer by the Company to repurchase each such Holder's CD&R
Barbados Notes on the applicable Mandatory Repurchase Date (subject to prorating
as described in Section 6.6(d)), for a purchase price equal to the Principal
Amount of Notes so repurchased (plus accrued and unpaid interest on the
Principal Amount thereof so repurchased to the date of repurchase). The
aggregate purchase price to be so applied to repurchase CD&R Barbados Notes
(excluding accrued and unpaid interest) shall be equal to (x) the aggregate
amount of such Net Proceeds not previously applied to permanently prepay Bank
Indebtedness under the Credit Agreement minus (y) the aggregate amount of such
Net Proceeds required to be applied to repurchase Fund VI Notes pursuant to
Section 6.6(a) of the Fund VI Investment Agreement minus (z) the Reinvested
Amount related thereto; provided that, notwithstanding the foregoing, any such
repurchase of CD&R Barbados Notes shall only be required upon any such sale,
transfer, other disposition or recovery (A) described in subsections 14.5(h),
(j) or (k) of the Credit Agreement (as in effect prior to giving effect to the
Second Credit Agreement Amendment), to the extent the Net Proceeds received
therefrom, when aggregated with the Net Proceeds received from all such sales,
transfers, other dispositions or recoveries in the immediately preceding
twelve-month period and minus all applicable Reinvested Amounts relating to all
such Net Proceeds, exceed $5,000,000 or (B) described in subsection 14.5(f) of
the Credit Agreement (as in effect prior to giving effect to the Second Credit
Agreement Amendment), to the extent the Net Proceeds received from any one such
sale and minus the applicable Reinvested Amounts relating to such Net Proceeds
exceeds $5,000,000 or to the extent that Net Proceeds received therefrom, when
aggregated with the Net Proceeds received from all

                                       30

<PAGE>

such sales and minus all applicable Reinvested Amounts relating to all such Net
Proceeds, exceed $10,000,000.

          (c)  Any notice of the Company's offer to repurchase CD&R Barbados
Notes given pursuant to this Section 6.6 shall be given as promptly as
practicable (and in any event, within three (3) Business Days) following the
date of receipt of any such Net Proceeds (except that if any such Net Proceeds
are eligible to be reinvested in accordance with the definition of "Reinvested
Amount" in Section 6.6(e) and the Company has not elected to reinvest such
proceeds, such notice shall be given on the earlier of (i) the date on which the
certificate of a Responsible Officer of the Company to such effect is delivered
to the Investor in accordance with such definition and (ii) the last day of the
period within which a certificate setting forth such election is required to be
delivered in accordance with such definition). If the Company shall not have
received a written response to such notice from any Holder of CD&R Barbados
Notes within ten (10) days after the date of posting of such notice to such
Holder, then the Company shall immediately send a second notice to such Holder.

          (d)  To accept a repurchase offer under this Section 6.6, a Holder of
CD&R Barbados Notes shall 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. If accepted, such offered
repurchase shall be due and payable on the applicable Mandatory Repurchase Date
or, if later, five (5) Business Days after the date of delivery of such notice
of acceptance to the Company. If, upon the expiration of the period for which a
repurchase offer under this Section 6.6 remains open, the aggregate Principal
Amount of the CD&R Barbados Notes surrendered by Holders exceeds the amount of
Net Proceeds available for payment, the Company will select the CD&R Barbados
Notes to be purchased on a pro rata basis.

          (e)  As used in this Section 6.6, the following terms shall have the
following meanings:

     "Adjustment Period" means the period from the date of this Agreement to the
first date on or after June 30, 2003 on which no Bank Default Event has occurred

<PAGE>

any such cash proceeds in the nature of principal and interest payments on
account of promissory notes or similar obligations), received by the Company and
its Subsidiaries in connection with such event, minus (b) the sum, without
duplication, of (i) any taxes reasonably estimated to be payable to any federal,

recording tax expenses and other costs and expenses) actually incurred in
connection with such event which are paid or payable by the Company and its
Subsidiaries, (iii) the amount of such net cash proceeds which are attributable
to (and payable to) minority interests, (iv) the amount of any reserve
reasonably maintained by the Company and its Subsidiaries with respect to
indemnification obligations owing pursuant to the definitive documentation
pursuant to which such event is consummated (with any unused portion of such
reserve to constitute Net Proceeds on the date upon which the indemnification
obligations terminate or such reserve is reduced other than in connection with a
payment), (v) the amount of Indebtedness (other than intercompany Indebtedness)
of any Person, or secured by a Lien permitted hereunder on or that otherwise

a sale or other disposition of property or assets referred to in this Section
6.6, appropriate amounts to be provided by the Company or any of its

     "Reinvested Amount" means, with respect to any sale, transfer or other
disposition of property or assets of the Company or any of its Subsidiaries or
any recovery of amounts under any property insurance policies, that portion of
the Net Proceeds thereof as shall, according to a certificate of a Responsible

sale or other disposition, be reinvested in the business of the Company and its
Subsidiaries in a manner consistent with the terms of this Agreement within

of the Net Proceeds within, and is diligently pursuing such project during, the
period of three hundred sixty (360) days from the receipt of such Net Proceeds);
provided that if any such certificate of a Responsible Officer is not delivered
to the Investor on the date of such sale or other disposition, any Net Proceeds
of such sale or other disposition shall be promptly (x) deposited in a cash

                                       32

<PAGE>

with the terms of the Credit Agreement, to the extent then required thereby (it

for the Secured Parties pursuant to the terms of the Intercreditor Agreement),
or applied to prepay revolving credit borrowings under the Credit Agreement
pending delivery of such certificate, (y) deposited in a cash collateral account
established in accordance with the terms of the Fund VI Investment Agreement at

          (f)  The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to this
Section 6.6. 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 6.6 by virtue
thereof.

          (g)  The provisions of this Section 6.6 are in addition to and not in
limitation of the provisions of Section 8.4.

     6.7  Issuance of Warrants Upon Early Redemption or Repurchase.

          (a)  Upon the consummation of any redemption or repurchase of Notes
prior to the Maturity Date (whether pursuant to any provision of this Article
VI, Section 8.4 or otherwise), the Parent shall, at its own expense, execute,
issue and deliver Warrants to the Holders of the Notes so redeemed or
repurchased as provided by this Section 6.7. With respect to each Holder
receiving Warrants under this Section 6.7, the Warrants shall (a) be
substantially in the form of Exhibit B hereto, with such changes as may be
reasonably requested by such Holder and approved by the Parent, (b) expire on
the Maturity Date, (c) have an initial exercise price, subject to adjustment in
accordance with the terms of the warrant, equal to the Conversion Price in
effect immediately prior to such repurchase or redemption, and (d) entitle its
Holder to purchase a number of shares of Common Stock (or other property) equal
to the number of shares of Common Stock (or other property) into which such
Holder's Notes were convertible immediately prior to their redemption or
repurchase. Each Holder entitled to receive Warrants under this Section 6.7
shall receive them in the form of a single warrant certificate (or such greater
number of warrant certificates in denominations of at least 1,000 shares as such
Holder

                                       33

<PAGE>

may request), delivered by the Parent to the registered address of such Holder
in the Register of Holders maintained by the Company in accordance with Section
6.8.

          (b)  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 exercise of the Warrants, no Warrant may be exercised
until such issuance upon exercise has been so approved in connection with the
stockholder approval of the issuance of Common Stock upon conversion of the
Notes as contemplated by Section 6.3(k). At any time prior to such approval,
upon the written request of holders of the Warrants, 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 exercise of the
Warrants, 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 exercise of the Warrants.

     6.8 Register of Holders. The Company shall keep, or shall cause to be kept,
by a Transfer Agent for the Notes or otherwise, a register (the "Register of
Holders") for the registration and transfer of Notes, in which register the
Company shall record (a) the name, address and facsimile number of each Holder
(subject to change by such Holder in accordance with Section 13.1) and (b) the
details of each transfer of one or more Notes made in accordance with Section
6.9, including the name and address of each transferee of one or more Notes. The
Person in whose name any Note shall be properly registered shall be deemed and
treated as the owner and holder thereof for all purposes hereof, and the Company
shall not be affected by any notice or knowledge to the contrary, other than in
accordance with Section 6.9.

     6.9 Exchange of Notes Upon Transfer. Upon surrender of any Note to the
Company (or the Transfer Agent for the Notes, if any), duly endorsed or
accompanied by a written instrument of transfer duly executed by the Holder or
such Holder's attorney duly authorized in writing, the Company shall execute and
deliver a new Note or Notes in exchange therefor, in an aggregate principal
amount equal to the unpaid Principal Amount of the surrendered Note. Each new
Note shall (i) be registered in the name of such Person as the Holder may
request, (ii) be (A) dated and bear interest from the date to which interest had
been paid on the surrendered Note or (B) dated the date of the surrendered Note
if no interest shall have been paid thereon and (iii) carry the same rights to
unpaid interest and interest to accrue that were carried by the surrendered
Note. Notes shall not be transferred in denominations of less than $1,000,000,
provided that a Holder may transfer its entire holding of Notes regardless of
the principal amount of such Notes. Each Holder may transfer any Note (or any
portion thereof) to any Person without the Company's consent, provided that any
such transfer of Notes by the Investor or any Holder that is a member of the
CD&R Group to any Person not a member of the CD&R Group shall cause the Liens
and Guarantees established with respect to such Transferred

                                       34

<PAGE>

Notes in accordance with the Guarantee and Collateral Agreement or any other
Note Security Documents to be irrevocably released, discharged and of no further
force or effect with respect to such Transferred Notes. The Company shall pay
the cost of executing, issuing and delivering the new Note or Notes to the home,
office or custodian bank of (or other location designated by) the Holder
thereof, insured to the reasonable satisfaction of such Holder. The Company may
require payment of a sum sufficient to cover any stamp tax or governmental
charge imposed in respect of any transfer of Notes.

     6.10 Mutilated, Destroyed, Lost and Stolen Notes.

          (a)  If (i) any mutilated Note is surrendered to the Company, or the
Company receives evidence reasonably satisfactory to it of the destruction, loss
or theft of any Note and (ii), in the case of any destroyed, lost or stolen
Note, there is delivered to the Company such security or indemnity as may be
required to hold the Company harmless, then, in the absence of notice to the
Company that such Note has been acquired by a bona fide purchaser, the Company
shall execute and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Note, a new Note of like tenor and principal amount,
bearing a number not contemporaneously outstanding. The Company may require
payment of a sum sufficient to cover its reasonable expenses and any stamp tax
or governmental charge imposed in respect of such issuance of a new Note.

          (b)  Every new Note issued pursuant to this Section 6.10 in lieu of
any mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Agreement and, as appropriate, the
other Transaction Agreements equally and ratably with any and all other duly
issued Notes.

          (c)  The provisions of this Section 6.10 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Notes.

                                  Article VII
                      Affirmative Covenants of the Company

     The Company hereby agrees that, from and after the date hereof and until

deliver or cause to be delivered to the Secured Parties any surveys, title
insurance policies, environmental reports and other documents in connection with

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).

     Secured Party to be necessary or reasonably advisable to cause the Lien
     created by the Guarantee and Collateral Agreement to be duly perfected in

     be reasonably requested by any Secured Party.

          (c)  With respect to any Person that, subsequent to the date hereof,

directly by the Company or any of its Domestic Subsidiaries (other than Acterna
WG) (provided that in no event shall more than sixty-five percent (65%) of the
Capital Stock of any such Subsidiary be required to be so pledged; and it being
understood that such Lien shall be subject to the Intercreditor Agreement) and

Subsidiaries pursuant to Section 8.15 of the Guarantee and Collateral Agreement.

          (e)  Comply with subsection 14.15 of the Credit Agreement (entitled
Limitation on Inactive Subsidiaries) as in effect on the Closing Date.

     7.10 Liens. If after the date hereof, the Company or any of its
Subsidiaries creates or suffers to exist a Lien on any of their respective
properties or assets securing any Bank Indebtedness, then the Company shall, and
shall cause each such Subsidiary to, create a Lien on such property or assets
securing the CD&R Barbados Notes pursuant to the Guarantee and Collateral
Agreement (or, if 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 Barbados 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 Barbados
Notes shall be subject to the Intercreditor Agreement).

     7.11 Note Guarantors.

          (a)  From and after the date hereof, the Company will cause each
Subsidiary that Guarantees payment of any Bank Indebtedness to execute and
deliver to each Holder of CD&R Barbados Notes an instrument pursuant to which
such Subsidiary will Guarantee payment of the CD&R Barbados Notes pursuant to
the Guarantee and Collateral Agreement (or, if requested by any Secured Party,
one or more other Note Security Documents in form and substance reasonably
satisfactory to the Secured

                                       43

Parties), whereupon such Subsidiary will become a Note Guarantor for all
purposes under this Agreement.

          (b)  From and after the date hereof, the Parent shall Guarantee
payment of the Transferred Notes in accordance with the terms of Annex A hereto.
From and after the date hereof, the Company will cause each Domestic Subsidiary
that is a Significant Subsidiary and that Guarantees Indebtedness of the Company
(other than Bank Indebtedness), to execute and deliver to each Holder of
Transferred Notes an instrument pursuant to which such Subsidiary will Guarantee
payment of the Transferred Notes in accordance with the terms of Annex A hereto,
whereupon such Subsidiary will become a Note Guarantor in respect of the
Transferred Notes for all purposes under this Agreement, provided, however, each
such Guarantee in respect of a Transferred Note (a "Springing Guarantee") by a
Domestic Significant Subsidiary (a "Significant Subsidiary Guarantor") will be
subject to termination and discharge under the following circumstances: Each
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)
in accordance with the terms of this Agreement of any Significant Subsidiary
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
(other than Bank Indebtedness) of the Company, (iv) upon the merger or
consolidation of any Significant Subsidiary Guarantor with and into the Company
or another Significant Subsidiary Guarantor that is the surviving Person in such
merger or consolidation and (v) upon payment in full of the aggregate principal
amount of all Transferred Notes then outstanding and all other Guaranteed
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).

                        Negative Covenants of the Company

          (a)   The Company will not, and will not permit any Restricted
Subsidiary to, Incur any Indebtedness, provided, however, that the Company or

     owed, or other event, that results in such Restricted Subsidiary ceasing to
     be a Restricted Subsidiary or any other subsequent transfer of such
     Indebtedness (except to the Company or a Restricted Subsidiary) will be
     deemed, in each case, an Incurrence of such Indebtedness by the issuer
     thereof;

     represented by the Fund VI Notes, any Indebtedness represented by the

     related fees and expenses) or to refinance any such acquisition, merger or

          (c)   For purposes of determining compliance with, and the outstanding
principal amount of any particular Indebtedness Incurred pursuant to and in
compliance with, this Section 8.1, (i) any other obligation of the obligor on
such Indebtedness (or of any other Person who could have Incurred such
Indebtedness under this Section 8.1) arising under any Guarantee, Lien or letter
of credit, bankers' acceptance or other similar instrument or obligation
supporting such Indebtedness shall be disregarded to the extent that such
Guarantee, Lien or letter of credit, bankers' acceptance or other similar
instrument or obligation secures the principal amount of such Indebtedness; (ii)
in the event that Indebtedness meets the criteria of more than one of the types
of Indebtedness described in paragraph (b) of this Section 8.1, the Company, in
its sole discretion, shall classify such item of Indebtedness and only be
required to include the amount and type of

                                       47

GAAP.

          (d)  For purposes of determining compliance with any United States
dollar-denominated restriction on the Incurrence of Indebtedness denominated in
a foreign currency, the United States dollar-equivalent principal amount of such
Indebtedness Incurred pursuant thereto shall be calculated based on the relevant
currency exchange rate in effect on the date that such Indebtedness was
Incurred, in the case of term Indebtedness, or first committed, in the case of
revolving credit Indebtedness, provided that (i) the United States
dollar-equivalent principal amount of any such Indebtedness outstanding on May
21, 1998 shall be calculated based on the relevant currency exchange rate in
effect on May 21, 1998, (ii) if such Indebtedness is Incurred to refinance other
Indebtedness denominated in a foreign currency, and such refinancing would cause
the applicable United States dollar-denominated restriction to be exceeded if
calculated at the relevant currency exchange rate in effect on the date of such
refinancing, such United States dollar-denominated restriction shall be deemed
not to have been exceeded so long as the principal amount of such refinancing
Indebtedness does not exceed the principal amount of such Indebtedness being
refinanced and (iii) the United States dollar-equivalent principal amount of
Indebtedness denominated in a foreign currency and Incurred pursuant to the
Credit Agreement shall be calculated based on the relevant currency exchange
rate in effect on, at the Company's option, (x) May 21, 1998, (y) any date on
which any of the respective commitments under the Credit Agreement shall be
reallocated between or among facilities or subfacilities thereunder, or on which
such rate is otherwise calculated for any purpose thereunder, or (z) the date of
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 which such respective Indebtedness is
denominated that is in effect on the date of such refinancing.

          (e)  The Company shall not Incur any Indebtedness that is subordinated
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
right of payment to any Note Guarantee of such Note Guarantor on terms no less
favorable to the Holders than the terms on which it is subordinated to such
other Indebtedness.

in each case due within one year of the date of such acquisition or retirement);
or (iv) make any Investment (other than a Permitted Investment) in any Person

          1998 to the end of the most recent fiscal quarter ending prior to the
          date of such Restricted Payment for which consolidated financial
          statements of the Company are available (or, in case such Consolidated

          dividends, distributions, interest payments, return of capital,
          repayments of Investments or other transfers of assets to the Company
          or any Restricted Subsidiary from any Unrestricted Subsidiary, or (y)
          the redesignation of any Unrestricted Subsidiary as a Restricted
          Subsidiary (valued in each case as provided in the definition of

          duplication of any amount deducted in calculating the amount of
          Investments at any time outstanding included in the amount of
          Restricted Payments), an amount in the aggregate equal to the lesser
          of the return of capital, repayment or other proceeds with respect to
          all such Investments and the initial amount of all such Investments.

          (b)  The provisions of subsection (a) of this Section 8.2 will not

          (iv)  Investments or other Restricted Payments in an aggregate amount
     outstanding at any time not to exceed the amount of Excluded Contributions,

     assets from any Person in a Related Business or the merger or consolidation
     of such a Person into or with the Company or any Restricted Subsidiary

modification to an Initial Agreement (an "Amendment"), provided, however, that

determined in good faith by the Company);

          (d)  (i) that restricts in a customary manner the subletting,

the principal of or interest on the Notes, (ii) relating to any sale of
receivables by a Foreign Subsidiary that is a Restricted Subsidiary or (iii)
relating to Indebtedness of or a Financing Disposition to or by any Receivables

     Disposition at least equal to the fair market value of the shares and
     assets subject to such Asset Disposition, as such fair market value may be
     determined (and shall be determined, to the extent such Asset Disposition
     or any series of related Asset Dispositions involves aggregate
     consideration in excess of $10,000,000) in good faith by the Board of
     Directors, whose determination shall be conclusive (including as to the
     value of all non-cash consideration);

          (ii)  in the case of any Asset Disposition (or series of related Asset
     Dispositions) having a fair market value of $10,000,000 or more, at least
     seventy-five percent (75%) of the consideration therefor (excluding, in the
     case of an Asset Disposition (or series of related Asset Dispositions) of

          required by the provisions of this Agreement or the terms of the
          Credit Agreement or of Indebtedness of a Restricted Subsidiary that is
          not a Note Guarantor of any of the Notes), to prepay, repay or
          purchase the Notes, the Fund VI Notes, the Bank Indebtedness under the
          Credit Agreement or such Indebtedness of a Restricted Subsidiary (in
          each case other than Indebtedness owed to the Company or a Restricted
          Subsidiary) within 365 days after the date of such Asset Disposition
          or (2) to the extent the Company or such Restricted Subsidiary elects,
          to reinvest in Additional Assets (including by means of an investment

          limited to the repurchase, repayment or other acquisition or
          retirement of any Subordinated Obligations to the extent otherwise
          permitted hereby);

provided, however, that in connection with any prepayment, repayment or purchase

accrued and unpaid interest to the date of such purchase in accordance with the
procedures (including prorating in the event of oversubscription) set forth in
paragraph (e) of this Section 8.4. If the aggregate purchase price of the Notes
tendered pursuant to the Offer is less than the Net Available Cash allotted to
the purchase of Notes, the remaining Net Available Cash will be available to the
Company for use in accordance with clause (iii)(C) of the subsection (a) of this
Section 8.4. The Company shall not be required to make an Offer for Notes
pursuant to this Section 8.4 if the Net Available Cash available therefor (after
application of the proceeds as provided in clause (iii)(A) of the first
paragraph of this Section 8.4) is less than $15,000,000 for any particular Asset
Disposition (which lesser amounts shall be carried forward for purposes of
determining whether an Offer is required with respect to the Net Available Cash
from any subsequent Asset Disposition).

          (e)  The Company will, not later than five (5) days after the Company
becomes obligated to make an Offer pursuant to this Section 8.4, mail a notice
to each Holder stating: (i) that an Asset Disposition that requires the purchase
of a portion of the Notes has occurred and that such Holder has the right
(subject to the prorating described below) to require the Company, to purchase a
portion of such Holder's Notes at a purchase price in cash equal to one hundred
percent (100%) of the Principal Amount thereof, plus accrued and unpaid
interest, if any, to the date of purchase; (ii) the circumstances and relevant
facts and financial information regarding such Asset Disposition; (iii) the
repurchase date (which shall be no earlier than forty-five (45) days nor later
than sixty (60) days from the date such notice is mailed); (iv) the instructions
determined by the Company, consistent with this Section 8.4, that a Holder must
follow in order to have its Notes purchased; and (v) the amount of the Offer.
If, upon the expiration of the period for which the Offer remains open, the
aggregate Principal Amount of Notes surrendered by Holders exceeds the amount of
the Offer, the Company will select the Notes to be purchased on a pro rata
basis.

          (f)  The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to this
Section 8.4. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 8.4, the Company will
comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under this Section 8.4 by virtue
thereof.

          (g)  The provisions of this Section 8.4 are in addition to and not in
limitation of the provisions of Section 6.6.

not a Permitted Lien securing any liability or obligation, the Company shall,
and shall cause each such Subsidiary to, make effective provision to secure the
Indebtedness due under the CD&R Barbados Notes or, in respect of Liens on any
Subsidiary's property or assets, any Note Guarantee of such Subsidiary in
respect of the CD&R Barbados Notes, (i) equally and ratably with any such

"Initial Lien"), unless contemporaneously therewith effective provision is made
to secure the Indebtedness due under the Transferred Notes or, in respect of
Liens on any Restricted Subsidiary's property or assets, any Note Guarantee of

                                       59

<PAGE>

such Restricted Subsidiary in respect of the Transferred Notes, (i) equally and
ratably with any such obligation that ranks pari passu in right of payment with
the Transferred Notes or (ii) prior to any such obligation that by its terms is
expressly subordinated in right of payment to the Transferred Notes, in each
case for so long as such obligation is so secured by such Initial Lien. Any such
Lien thereby created in favor of the Transferred Notes or any such Note
Guarantee will be automatically and unconditionally released and discharged upon
(i) the release and discharge of the Initial Lien to which it relates, or (ii)
any sale, exchange or transfer to any Person not an Affiliate of the Company of
the property or assets secured by such Initial Lien, or of all of the Capital
Stock held by the Company or any Restricted Subsidiary in, or all or
substantially all the assets of, any Restricted Subsidiary creating such Lien.

     the terms of the Senior Subordinated Notes or the Senior Subordinated Note
     Indenture which (i) amends or modifies the subordination provisions
     contained in the Senior Subordinated Notes and the Senior Subordinated Note
     Indenture, (ii) shortens the fixed maturity or increases the principal
     amount of, or increases the rate or shortens the time of payment of

     prepayment or by acceleration or otherwise of the Indebtedness evidenced by
     the Senior Subordinated Notes or increases the amount of, or accelerates
     the time of payment of, any fees or other amounts payable in connection
     therewith to any holder of the Senior Subordinated Notes, (iii) relates to
     any material affirmative or negative covenants or any events of default or

     Holders.

     8.8  Limitation on Negative Pledge Clauses. The Company shall not, and
shall not permit any of its Subsidiaries to, directly or indirectly, enter into
any agreement which prohibits or limits the ability of the Company or any of its

its property or revenues, whether now owned or hereafter acquired, to secure the
obligations under the CD&R Barbados Notes or any Note Financing Document to the

consequences if the rescission would not conflict with any judgment or decree

upon the Holders is intended to be exclusive of any other right or remedy, and

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

Company from paying all or any portion of the principal of (or premium, if any)
or interest on the Notes contemplated herein or in the Notes or that may affect
the covenants or the performance of this Agreement.

<PAGE>

rise to the need to calculate the Consolidated Coverage Ratio involves a
Discharge of Indebtedness (in each case other than Indebtedness Incurred under
any revolving credit facility unless such Indebtedness has been permanently
repaid), Consolidated EBITDA and Consolidated Interest Expense for such period
shall be calculated after giving effect on a pro forma basis to such Discharge
of such Indebtedness, including with the proceeds of such new Indebtedness, as
if such Discharge had occurred on the first day of such period;

          (c) if since the beginning of such period the Company or any
Restricted Subsidiary shall have disposed of any company, any business or any
group of assets constituting an operating unit of a business (any such
disposition, a "Sale"), the Consolidated EBITDA for such period shall be reduced
by an amount equal to the Consolidated EBITDA (if positive) attributable to the

amount equal to the Consolidated EBITDA (if negative) attributable thereto for
such period and Consolidated Interest Expense for such period shall be reduced
by an amount equal to (i) the Consolidated Interest Expense attributable to any
Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased,
redeemed, defeased or otherwise acquired, retired or discharged with respect to
the Company and its continuing Restricted Subsidiaries in connection with such
Sale for such period (including but not limited to through the assumption of

Company and its continuing Restricted Subsidiaries are no longer liable for such
Indebtedness after such Sale;

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
EBITDA and Consolidated Interest Expense for such period shall be calculated
after giving pro forma effect thereto (including the Incurrence of any related
Indebtedness) as if such Purchase occurred on the first day of such period; and

          (e) if since the beginning of such period any Person became a
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
shall have Discharged any Indebtedness or made any Sale or Purchase that would
have required an adjustment pursuant to clause (b), (c) or (d) above if made by
the Company or a Restricted Subsidiary during such period, Consolidated EBITDA
and Consolidated

                                       74

<PAGE>

Interest Expense for such period shall be calculated after giving pro forma
effect thereto as if such Discharge, Sale or Purchase occurred on the first day
of such period.

For purposes of this definition, whenever pro forma effect is to be given to any
Sale, Purchase or other transaction, or the amount of income or earnings
relating thereto and the amount of Consolidated Interest Expense associated with
any Indebtedness Incurred or repaid, repurchased, redeemed, defeased or
otherwise acquired, retired or discharged in connection therewith, the pro forma
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 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.

Stock (other than Disqualified Stock) of the Company and (e) the amount of any
minority interest expense.

Company or a Restricted Subsidiary as a dividend or other distribution (subject,
in the case of a dividend or other distribution to a Restricted Subsidiary, to
the limitations contained in clause (c) below) and (ii) the Company's equity in
the net loss of such Person shall be included to the extent of the aggregate
Investment of the Company or any of its Restricted Subsidiaries in such Person;

          (b) any net income (loss) of any Person acquired by the Company or a

          (i)  No delay or omission of any Holder to exercise any right, remedy,

     13.8  Survival of Representations and Warranties. All representations and
warranties made hereunder, in the other Transaction Agreements and in any
certificate delivered pursuant hereto or in connection herewith shall survive

     13.9  Payment of Expenses and Taxes.

           (a)  The Company agrees (i) to pay or reimburse each Holder for all
its reasonable out-of-pocket costs and expenses incurred in connection with the
preparation and execution of, and any amendment, supplement or modification to,
or proposed amendment, supplement or modification to, this Agreement and the
other Transaction Agreements and any other documents prepared in connection
herewith or therewith, and the consummation and administration of the
transactions contemplated hereby and thereby, including, without limitation, the
reasonable fees and disbursements of counsel to the Holders; (ii) to pay or
reimburse each Holder for all its reasonable costs and expenses incurred in
connection with the enforcement or preservation of any rights under this
Agreement, the other Transaction Agreements and any such other documents,
including, without limitation, the reasonable fees and disbursements of counsel
to the Holders; (iii) to pay, indemnify, and hold each Holder harmless from, any
and all recording and filing fees and any and all liabilities with respect to,
or resulting from any delay in paying, stamp, excise and other similar taxes, if
any, which may be payable or determined to be payable in connection with the
execution and delivery of, or consummation or administration of any of the
transactions contemplated by, or any amendment, supplement or modification of,
or any waiver or consent under or in respect of, this Agreement, the other
Transaction Agreements and any such other documents and (iv) to pay, indemnify,
and hold harmless each Holder from and against any and all other liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever with respect to the
execution, delivery, enforcement, performance and administration of this
Agreement, the other Transaction Agreements and any such other documents, or the
use of the proceeds of the Notes, including, without limitation, any of the
foregoing relating to the violation of, noncompliance with or liability under,
any Environmental Law applicable to the operations of the Company, any of its
Subsidiaries or any of the Properties (all the foregoing in this clause (iv),
collectively, the "indemnified liabilities"), provided that the Company shall
have no obligation under this Section 13.9(a)(iv) to any Holder with respect to
indemnified liabilities arising from (A) the gross negligence or willful
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

                                       110

<PAGE>

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

                                       111

<PAGE>

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.

     13.11  Entire Agreement. This Agreement and the other Transaction
Agreements (when executed and delivered) constitute the entire agreement and
supersede all prior agreements and understandings, both written and oral,
between the parties with respect to the subject matter hereof and thereof.

     13.12  Severability. If any provision of this Agreement is held to be
invalid or unenforceable for any reason, it shall be adjusted rather than
voided, if possible, in order to achieve the intent of the parties hereto to the
maximum extent possible. In any event, the invalidity or unenforceability of any

                                                                         Annex A

                  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.

<PAGE>

     (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

<PAGE>

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

<PAGE>

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.

                   Series 2-[A][B][C][D][E][F][G][H][I][J][K]

No. [__________]
Date of Issuance:  [__________]

                                                                   $[__________]

         Acterna LLC (together with its successors and assigns, the "Company"),
a Delaware limited liability company wholly-owned and controlled by Acterna
Corporation (together with its successors and assigns, the "Parent"), hereby
promises to pay to [____________________], or registered assigns, the principal
sum of [____________________] United States Dollars ($[__________]) (the
"Principal Amount") on December 31, 2007 (the "Maturity Date") or, if such date
is not a Business Day, the next succeeding Business Day.

         1. Interest. The Company promises to pay interest semi-annually, in
arrears, on each March 31st and September 30th (each, an "Interest Payment
Date") of each year (commencing on the later of March 31, 2003 and the Interest
Payment Date next succeeding the date of issuance of this Note) at the rate of
[__] percent ([__]%) per annum (the "Interest Rate"), until the Principal Amount
of this Note shall have become due and payable. Interest on this Note shall be
computed on the basis of a three hundred sixty (360) day year of twelve (12)
thirty (30) day months. The interest payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Investment
Agreement, be paid to the Holder in whose name this Note is registered at the
close of business on the applicable Interest Payment Date. 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
(x) the highest rate allowed by applicable law and (y) the Interest Rate plus
two percent (2%).

         2. Method of Payment.

                (a) Payments of principal and accrued and unpaid interest on
         this Note 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.

                (b) Notwithstanding the foregoing, at the option of the Company,
         payments of accrued and unpaid interest may be made by the issuance of
         an additional Note (i) substantially in the form of this Note, (ii)
         registered in the name of the Holder, (iii) bearing interest at the
         Interest Rate and (iv) having a face value equal to the amount of the
         applicable interest payment. In the event that a payment of accrued and
         unpaid interest 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.

         3. The Investment Agreement. This Note is one of the duly-authorized
issue of Senior Secured Convertible Notes Due 2007, Series 2 of the Company

         4. Guarantees and Collateral. This Note is entitled to the benefits of
(a) certain Liens on certain assets and property of the Parent, the Company and
certain Subsidiaries of the Company and (b) Note Guarantees of the Parent and
certain Subsidiaries of the Company made for the benefit of the Holders.
Reference is made to the Investment Agreement and (if applicable) to the
Guarantee and Collateral Agreement referred to in the Investment Agreement.
Neither the Parent, the Company nor any Subsidiary of the Company shall be
required to make any notation on this Note to reflect any such Lien or Note
Guarantee or any release, termination or discharge thereof.

         5. Conversion.

                (a) Subject to and upon the terms set forth in the Investment
         Agreement, at the option of the Holder hereof, this 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 in effect at the time of conversion. Such
         conversion right shall commence on the initial issuance date of this
         Note and expire at the close of business on the Maturity Date. The rate
         at which shares of Common Stock shall be delivered upon conversion (the
         "Conversion Rate") shall be initially [_________________________]
         [(____)] shares of Common Stock for each $1,000 Principal Amount of
         Notes. The Conversion Rate will be adjusted by the Company in certain
         instances as provided in the Investment 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 this Note will be increased or decreased, as appropriate.)

                (b) In case this Note (or portion hereof) is called for
         redemption at the election of the Company or the Holder hereof
         exercises his right to require the Company to repurchase the Note
         following a Change of Control, the conversion right in respect of the
         Note, or portion thereof so called, will 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.

         6. Optional Redemption. Subject to and upon the terms set forth in the
Investment Agreement, the Company may, at its option, redeem (each, an "Optional
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

                                       3

Amount) and in integral multiples of $1,000,000, or in whole, in each case
together with accrued but unpaid interest on such Principal Amount to the date
of redemption.

         7. Repurchases. Subject to and upon the terms set forth in the
Investment Agreement, the Company shall offer to repurchase the Notes in the
event of a change of control and upon certain asset dispositions.

         8. Issuance of Warrants Upon Early Redemption or Repurchase. Subject to
and upon the terms set forth in the Investment Agreement, upon the consummation
of any redemption or repurchase of Notes prior to the Maturity Date (whether
pursuant to Article VI and Section 8.4 or otherwise), the Parent shall, at its
own expense issue and deliver Warrants to the Holders of the Notes so redeemed
or repurchased. Each Warrant shall (a) expire on the Maturity Date, (b) have an
initial exercise price, subject to adjustment in accordance with its terms,
equal to the Conversion Price in effect immediately prior to such repurchase or
redemption and (c) entitle its Holder to purchase a number of shares of Common
Stock (or other property) equal to the number of shares of Common Stock (or
other property) into which such Holder's Notes were convertible immediately
prior to their redemption or repurchase.

         9. Denominations; Transfer; Exchange. The Notes are in registered form
without coupons in denominations of at least $1,000. A Holder may transfer or
exchange Notes in accordance with the Investment Agreement, subject to the
limitations set forth in the Investment Agreement and provided that any transfer
of CD&R Barbados Notes by the Investor or any Holder that is a member of the
CD&R Group to any Person not a member of the CD&R Group shall cause certain
Liens and Guarantees established with respect to such CD&R Barbados Notes to be
released, discharged and of no further force or effect with respect to such
Notes. No charge shall be made by the Company for any transfer or exchange of
Notes, but the Company may require payment of a sum sufficient to cover any
stamp tax or other governmental charge that may be imposed in connection
therewith.

         10. Persons Deemed Owners. The registered Holder of this Note may be
treated as the owner of it for all purposes.

         11. Defaults and Remedies. If an Event of Default with respect to the
Notes occurs and is continuing, the Notes may become or be declared due and
payable immediately in the manner and with the effect provided in the Investment
Agreement.

         12. Amendment, Waiver. The Investment Agreement and the Notes may be
amended as specified in the Investment Agreement.
