                                   EXHIBIT 4.4

                      NON-QUALIFIED STOCK OPTION AGREEMENT
                      ------------------------------------

     THIS STOCK OPTION AGREEMENT (the "Agreement") entered into as of this 24th
day of August, 2001, between SFBC International, Inc. (the "Company") and Jerry
Seifer the "Employee"), an employee of the Company.

     WHEREAS, the Employee has acquired certain unvested stock options (the
"Options") from Roger Taft ("Taft") pursuant to an agreement with Taft which
Options were not issued under the Company's 1999 Stock Option Plan; and

     WHEREAS, under the terms of that agreement the Employee is required to
enter into a stock option agreement containing similar vesting terms to that
which Taft had with the Company.

     NOW THEREFORE, in consideration of the mutual covenants and promises
hereafter set forth and for other good and valuable consideration, the receipt
of which is hereby acknowledged, the parties hereto agree as follows:

     1. Acknowledgement of Options. The Company acknowledges that the Employee
        --------------------------
holds 62,500 Options, 32,500 exercisable at $6.00 per share and 30,000 at $7.50
per share, each Option to purchase one share of common stock.

     2. Vesting-When Exercisable.
        ------------------------

       (a) The Options shall vest over three years in five equal increments on
June 30 and December 31 of each year beginning December 31, 2001, as long as the
Employee remains employed on each applicable vesting date. In lieu of fractional
vesting, the number of Options shall be rounded up each time until fractional
Options are eliminated.

The vesting date of all Options shall accelerate in the event of any of the
following: (i) the Company is to merge or consolidate with or into any other
corporation or entity except a transaction where the Company is the surviving
corporation or a change of domicile merger or similar transaction exempt from
registration under the Securities Act of 1933, (ii) the sale of all or
substantially all of the Company's assets, (iii) the sale of at least 90% of the
outstanding common stock of the Company to a third party (subsections (i), (ii)
and (iii) collectively referred to as an "Acquisition"); or (iv) the Company is
dissolved. Upon a minimum of 20 days prior written notice to the Employee, the
exercisability of such Options shall commence two business days prior to the
earlier of (A) the scheduled closing of an Acquisition or proposed dissolution
or (B) the actual closing of an Acquisition or proposed dissolution.

       (b) Subject to Sections 2(c) and 3 of this Agreement, Options may be
exercised prior to vesting and remain exercisable through January 16, 2011.

       (c) However, notwithstanding any other provision of this Agreement, all

                                        1

<PAGE>

Options, whether vested or unvested shall be immediately forfeited in the event
of:

             (1) Termination of employment for any reason including without
cause and including, but not limited to, fraud, theft, employee dishonesty and
violation of Company policy;

             (2) Purchasing or selling securities of the Company without written
authorization in accordance with the Company's inside information guidelines
then in effect;

             (3) Breaching any duty of confidentiality including that required
by the Company's inside information guidelines then in effect;

             (4) Competing with the Company;

             (5) Being unavailable for consultation after leaving the Company's
employ if such availability is a condition of any agreement between the Company
and the Employee;

             (6) Recruitment of Company personnel after termination of
employment, whether such termination is voluntary or for cause;

             (7) Failure to assign any invention or technology to the Company if
such assignment is a condition of employment or any other agreements between the
Company and the Employee; or

             (8) A finding by the Company's Board that the Employee has acted
against the interests of the Company.

     3.  Termination of Relationship.
         ---------------------------

         (a) If for any reason, except death or disability as provided below,
the Employee ceases to act as an employee of the Company, all rights granted
hereunder shall terminate effective three months from the date the Employee
ceases to act as an employee, except as otherwise provided for herein.

         (b) If the Employee shall die while an employee of the Company, his
estate or any Transferee, as defined herein, shall have the right within one
year from the date of the Employee's death to exercise the Employee's vested
Options subject to Section 2(c). For the purpose of this Agreement, "Transferee"
shall mean a person to whom such shares are transferred by will or by the laws
of descent and distribution.

         (c) No transfer of the Options by the Employee by will or by the laws
of descent and distribution shall be effective to bind the Company unless the
Company shall have been furnished with written notice thereof and a copy of the
letters testamentary or such other evidence as the Board may deem necessary to
establish the authority of the state and the acceptance by the Transferee or
Transferees of the terms and conditions of the Options.

                                       2

<PAGE>

        (d) If the Employee becomes disabled while employed by the Company
within the meaning of Section 22(e)(3) of the Code, the three month period
referred to in Section 4(a) of this Agreement shall be extended to one year.

     4. Profits on the Sale of Certain Shares; Redemption. If any of the events
        -------------------------------------------------
specified in Section 2(c) of this Agreement occur within one year from the last
date of employment (the "Termination Date") (or such longer period required by
any written employment agreement), all profits earned from the sale of the
Company's securities, including the sale of shares of common stock underlying
Options, during the two-year period commencing one year prior to the Termination
Date shall be forfeited and forthwith paid by the Employee to the Company.
Further, in such event, the Company may at its option redeem shares of common
stock acquired upon exercise of Options. The Company's rights under this Section
4 do not lapse one year from the Termination Date but are a contract right
subject to any appropriate statutory limitation period.

     5. Method of Exercise. The Options shall be exercisable by a written notice
        ------------------
which shall:

        (a) state the election to exercise the Options, the number of shares to
be exercised, the person in whose name the stock certificate or certificates for
such shares of common stock is to be registered, his address and social security
number (or if more than one, the names, addresses and social security numbers of
such persons);

        (b) contain such representations and agreements as to the holder's
investment intent with respect to such shares of common stock as set forth in
Section 10 hereof;

        (c) be signed by the person or persons entitled to exercise the Options
and, if the Options are being exercised by any person or persons other than the
optionee, be accompanied by proof, satisfactory to counsel for the Company, of
the right of such person or persons to exercise the Options.

        (d) be accompanied by full payment of the purchase or exercise price
therefor in United States dollars by check.

     The certificate or certificates for shares of common stock as to which the
Options shall be exercised shall be registered in the name of the person or
persons exercising the Options.

     6. Sale of Shares Acquired Upon Exercise of Options. Any shares of the
        ------------------------------------------------
Company's common stock acquired pursuant to Options granted hereunder cannot be
sold by the Employee until at least one year elapses from the date of exercise,
unless a registration statement covering the sale of the common stock is in
effect.

     7. Adjustments. Upon the occurrence of any of the following events, the
        -----------
Employee's rights with respect to Options granted to him hereunder shall be
adjusted as hereinafter provided unless otherwise specifically provided in a
written agreement between the Employee and the Company relating to such Options:

                                       3

<PAGE>

        (a) If the shares of common stock shall be subdivided or combined into a
greater or smaller number of shares or if the Company shall issue any shares of
its common stock as a stock dividend on its outstanding common stock, the number
of shares of common stock deliverable upon the exercise of Options shall be
appropriately increased or decreased proportionately, and appropriate
adjustments shall be made in the purchase price per share to reflect such
subdivision, combination or stock dividend.

        (b) If the Company is to be consolidated with or acquired by another
entity pursuant to an Acquisition, the Board of any entity assuming the
obligations of the Company hereunder (the "Successor Board") shall either (i)
make appropriate provision for the continuation of such Options by substituting
on an equitable basis for the shares then subject to such Options the
consideration payable with respect to the outstanding shares of common stock in
connection with the Acquisition; or (ii) terminate all Options in exchange for a
cash payment equal to the excess of the fair market value of the shares subject
to such Options over the exercise price thereof.

        (c) In the event of a recapitalization or reorganization of the Company
(other than a transaction described in Section 7(b) above) pursuant to which
securities of the Company or of another corporation are issued with respect to
the outstanding shares of common stock, the Employee upon exercising Options
shall be entitled to receive for the purchase price paid upon such exercise the
securities he would have received if he had exercised his Options prior to such
recapitalization or reorganization.

        (d) Except as expressly provided herein, no issuance by the Company of
shares of common stock of any class or securities convertible into shares of
common stock of any class shall affect, and no adjustment by reason thereof
shall be made with respect to, the number or price of shares subject to Options.
No adjustments shall be made for dividends or other distributions paid in cash
or in property other than securities of the Company.

        (e) No fractional shares shall be issued and the Employee shall receive
from the Company cash in lieu of such fractional shares.

        (f) The Board or the Successor Board shall determine the specific
adjustments to be made under this Section 7, and its determination shall be
conclusive. If the Employee receives securities or cash in connection with a
corporate transaction described in Section 7(a), (b) or (c) above as a result of
owning such restricted common stock, such securities or cash shall be subject to
all of the conditions and restrictions applicable to the restricted common stock
with respect to which such securities or cash were issued, unless otherwise
determined by the Board or the Successor Board.

     8. Necessity to Become Holder of Record. Neither Employee nor his/her
        ------------------------------------
estate, as provided in Section 3(c), shall have any rights as a stockholder with
respect to any shares covered by the Options until such person shall have become
the holder of record of such shares. No adjustment shall be made for cash
dividends or cash distributions, ordinary or extraordinary, in respect of such
shares for which the record date is prior to the date on which he/she shall
become the holder of record thereof.

                                       4

<PAGE>

     9.  Reservation of Right to Terminate Relationship. Nothing contained in
         ----------------------------------------------
this Agreement shall restrict the right of the Company to terminate the
relationship of the Employee at any time, with or without cause. The termination
of the relationship of the Employee by the Company, regardless of the reason
therefor, shall have the results provided for in Sections 3 and 4 of this
Agreement.

     10. Conditions to Exercise of Options. In order to enable the Company to
         ---------------------------------
comply with the Securities Act of 1933 (the "Securities Act") and relevant state
law, the Company may require the Employee, his estate, or any Transferee, as a
condition of the exercising of the Options granted hereunder, to give written
assurance satisfactory to the Company that the shares subject to the Options are
being acquired for his own account, for investment only, with no view to the
distribution of same, and that any subsequent resale of any such shares either
shall be made pursuant to a registration statement under the Securities Act and
applicable state law which has become effective and is current with regard to
the shares being sold, or shall be pursuant to an exemption from registration
under the Securities Act and applicable state law.

     The Options are subject to the requirement that, if at any time the Board
shall determine, in its discretion, that the listing, registration, or
qualification of the shares of common stock subject to the Options upon any
securities exchange or under any state or federal law, or the consent or
approval of any governmental regulatory body, is necessary as a condition of, or
in connection with the issue or purchase of shares under the Options, the
Options may not be exercised in whole or in part unless such listing,
registration, qualification, consent or approval shall have been effected.

     11. Duties of Company. The Company shall at all times during the term of
         -----------------
Options:

         (a) Reserve and keep available for issue such number of shares of its
authorized and unissued common stock as will be sufficient to satisfy the
requirements of this Agreement;

         (b) Pay all original issue taxes with respect to the issue of shares
pursuant hereto and all other fees and expenses necessarily incurred by the
Company in connection therewith;

         (c) Use its best efforts to comply with all laws and regulations which,
in the opinion of counsel for the Company, shall be applicable thereto.

     12. Severability. In the event any parts of this Agreement are found to be
         ------------
void, the remaining provisions of this Agreement shall nevertheless be binding
with the same effect as though the void parts were deleted.

     13. Arbitration. Any controversy, dispute or claim arising out of or
         -----------
relating to this Agreement, or its interpretation, application, implementation,
breach or enforcement which the parties are unable to resolve by mutual
agreement, shall be settled by submission by either party of the controversy,
claim or dispute to binding arbitration in Miami-Dade County, Florida (unless
the parties agree in writing to a different location), before a single
arbitrator in accordance with the rules of the American Arbitration Association
then in effect. The decision and award made by the

Investment or acquisition of assets that would have required an adjustment
pursuant to clause (C) or (D) above if made by the Corporation or a Restricted
Subsidiary during such period, EBITDA and Consolidated Interest Expense for such
period shall be calculated after giving pro forma effect thereto as if such
Asset Sale, Investment or acquisition had occurred on the first day of such
period. For purposes of this definition whenever pro forma effect is to be given
to an acquisition of assets, the amount of income or earnings relating thereto
and the amount of Consolidated Interest Expense associated with any Indebtedness
incurred in connection therewith, the pro forma calculations shall be determined
in good faith by a responsible financial or accounting officer of the
Corporation. If any Indebtedness bears a floating rate of interest and is being

have no rights under this Indenture with respect to any Global Security held on
their behalf by the Depository, or the Trustee as its custodian, or under the
Global Security, and the Depository may be treated by the Corporation, the
Trustee and any agent of the Corporation or the Trustee as the absolute owner of
the Global Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Corporation, the Trustee or any Agent of the
Corporation or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by the Depository or impair, as between
the Depository and its Agent Members, the operation of customary practices
governing the exercise of the rights of a holder of any Security.

          (2) Transfers of the Global Security shall be limited to transfers in
whole, but, subject to the immediately succeeding sentence, not in part, to the
Depository, its successors or their respective nominees. Interests of beneficial
owners in the Global Security may be transferred or exchanged for Physical
Securities in accordance with the rules and procedures of the Depository and the
provisions of Section 2.09 hereof. In addition, Physical Securities shall be
transferred to all beneficial owners in exchange for their beneficial interests
in the Global Security if (i) the Depository notifies the Corporation that it is
unwilling or unable to continue as Depository for the Global Security and a
successor depositary is not appointed by the Corporation within 90 days of such
notice or (ii) an Event of Default has occurred and is

                                    18

continuing and the Registrar has received a written request from the Depository
to issue Physical Securities.

          (3) In connection with any transfer or exchange of a portion of the
beneficial interest in the Global Security to beneficial owners pursuant to
paragraph (2), the Registrar shall (if one or more Physical Securities are to be
issued) reflect on its books and records the date and a decrease in the
principal amount of the Global Security in an amount equal to the principal
amount of the beneficial interest in the Global Security to be transferred, and
the Corporation shall execute, and the Trustee shall authenticate and deliver,
one or more Physical Securities of like tenor and amount.

          (4) In connection with the transfer of the beneficial interests in the
entire Global Security to beneficial owners pursuant to paragraph (2), the
Global Security shall be deemed to be surrendered to the Trustee for
cancellation, and the Corporation shall execute, and the Trustee shall,
authenticate and deliver to each beneficial owner identified by the Depository
in exchange for its beneficial interest in the Global Security, an equal
aggregate principal amount of Physical Securities of authorized denominations.

          (5) The owner of a beneficial interest in the Global Security may
grant proxies and otherwise authorize any person, including Agent Members and
persons that may hold interests through Agent Members, to take any action which
a Holder is entitled to take under this Indenture or the Securities.

          SECTION 2.09 Special Transfer Provisions.
                       ---------------------------

          (1) Any Security authenticated and issued hereunder may be transferred
or otherwise exchanged as provided in Section 3.6 of the Exchange Agreement.

          (2) The following provisions shall apply with respect to the
registration of any proposed transfer of a Security:

          (a) If the proposed transferor is an Agent Member holding a beneficial
     interest in the Global Security, upon receipt by the Registrar of written
     instructions given in accordance with the Depository's and the Registrar's
     procedures, (i) the Registrar shall reflect on its books and records the
     date and if the transfer does not involve a transfer of outstanding
     Physical Securities) a decrease in the principal amount of the Global Note
     in an amount equal to the principal amount of the beneficial interest in
     the Global Note to be transferred, and (ii) the Corporation shall execute
     and the Trustee shall authenticate and deliver one or more Physical
     Securities of like tenor and amount.

          (b) If the proposed transferee is an Agent Member (and the Securities
     to be transferred consist of Physical Securities which after transfer are
     to be evidenced by an interest in the Global Security), upon receipt by the
     Registrar of written instructions given in accordance with the Depository's
     and the Security Registrar's procedures, (i) the Registrar shall reflect on
     its books and records the date and an increase in the principal amount of
     the Global Security in an amount equal to the principal amount of the
     Physical Securities to be transferred, and (ii) the Trustee shall cancel
     the Physical Securities so transferred.

                                    19

<PAGE>

          The Registrar shall retain copies of all letters, notices and other
written communications received pursuant to Section 2.08 hereof or this Section
2.09. The Corporation shall have the right to inspect and make copies of all
such letters, notices or other written communications at any reasonable time
during the Registrar's normal business hours upon the giving of reasonable
written notice to the Registrar.

          In connection with any transfer of the Securities, the Trustee, the
Registrar and the Corporation shall be entitled to receive, shall be under no
duty to inquire into, may conclusively presume the correctness of, and shall be
fully protected in relying upon the certificates, opinions and other information
referred to herein (or in the forms provided herein, attached hereto or to the
Securities, or otherwise) received from any Holder and any transferee of any
Security regarding the validity, legality and due authorization of any such
transfer, the eligibility of the transferee to receive such Security and any
other facts and circumstances related to such transfer.

          SECTION 2.10 Replacement Securities. If a mutilated Security is
                       ----------------------
surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Corporation shall
issue and the Trustee shall authenticate a replacement Security if the
requirements of Section 8-405 of the Uniform Commercial Code are met and the
Holder satisfies any other reasonable requirements of the Trustee. If required
by the Trustee or the Corporation, such Holder shall furnish an indemnity bond
sufficient in the judgment of the Corporation and the Trustee to protect the
Corporation, the Trustee, the Paying Agent, the Registrar and any co-registrar
from any loss which any of them may suffer if a Security is replaced. The
Corporation and the Trustee may charge the Holder for their expenses in
replacing a Security.

          Every replacement Security is an additional obligation of the
Corporation.

          SECTION 2.11 Outstanding Securities. Securities outstanding at any
                       ----------------------
time are all Securities authenticated by the Trustee except for those canceled
by it and those delivered to it for cancellation and those described in this
Section as not outstanding. A Security does not cease to be outstanding because
the Corporation or an Affiliate of the Corporation holds the Security.

          If a Security is replaced pursuant to Section 2.10, it ceases to be
outstanding unless the Trustee and the Corporation receive proof satisfactory to
them that the replaced Security is held by a bona fide purchaser.

          If the Paying Agent (other than the Corporation or a Subsidiary) holds
in trust, in accordance with this Indenture, on a redemption date or maturity
date money sufficient to pay all amounts payable on that date with respect to
the Securities (or portions thereof) and is not prohibited from paying such
money to the Holders thereof pursuant to the terms of this Indenture, then on
and after that date such Securities (or portions thereof) cease to be
outstanding and interest on them ceases to accrue.

          If a Security is called for redemption or if it matures in less than a
year and if the Corporation has satisfied its obligation to pay the Security in
accordance with Article 9 of this Indenture, the Corporation and the Trustee
need not treat the Security as outstanding in

                                    20

<PAGE>

determining whether Holders of the required principal amount of Securities have
concurred in any direction, waiver or consent.

          SECTION 2.12 Temporary Securities. Until definitive Securities are
                       --------------------
ready for delivery, the Corporation may prepare and the Trustee shall
authenticate temporary Securities. Temporary Securities shall be substantially
in the form of definitive Securities but may have variations that the
Corporation considers appropriate for temporary Securities. Without unreasonable
delay, the Corporation shall prepare and the Trustee, upon receipt of the
Corporation's written order signed by two Officers which shall specify the
amount of definitive Securities to be authenticated, and the date thereof, shall
authenticate definitive Securities and deliver them in exchange for temporary
Securities.

          SECTION 2.13 Cancellation. The Corporation at any time may deliver
                       ------------
Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for transfer,
exchange or payment. The Trustee and no one else shall cancel and destroy
(subject to the record retention requirements of the Exchange Act) all
Securities surrendered for transfer, exchange, payment or cancellation and
deliver a certificate of such destruction to the Corporation unless the
Corporation directs the Trustee to deliver canceled Securities to the
Corporation. The Corporation may not issue new Securities to replace Securities
it has redeemed, paid or delivered to the Trustee for cancellation.

          SECTION 2.14 Additional Securities. Additional Securities issued
                       ---------------------
pursuant to this Indenture and the Securities shall be governed by and entitled
to the benefits of this Indenture and the Security Agreement, shall be issued in
substantially the form of Exhibit A hereto, and shall be subject to the same
terms (including the rate of interest) as the Securities originally issued
hereunder, except, as the case may be, with respect to the issue date, the
principal amount and the payment of interest scheduled to be paid prior to or on
the date of issuance of such additional Securities. The Corporation shall notify
the Trustee in writing of its election to pay interest on the Securities on any
payment date in additional Securities at least five but not more than thirty
days prior to the record date for the payment date.

          SECTION 2.15 Defaulted Interest. If the Corporation defaults in a
                       ------------------
payment of interest on the Securities, it shall pay the defaulted interest
(plus, to the extent permitted by applicable law, interest on such defaulted
interest at the rate borne by the Securities plus 1%) in any lawful manner to
the persons who are Securityholders on a subsequent special record date, which
date shall be at least five business days prior to the special payment date. The
Corporation shall fix the special record date and special payment date, which
special record date shall be at least 10 days before the special payment date,
and the Corporation, or the Trustee in the name of and at the expense of the
Corporation, shall promptly mail to each Securityholder a notice that states the
special record date, the special payment date and the amount of defaulted
interest to be paid.

          SECTION 2.16 CUSIP Numbers. The Corporation in issuing the Securities
                       -------------
may use "CUSIP" numbers (if then generally in use) and, if so, the Trustee shall
use "CUSIP" numbers in notices of redemption or notices of optional prepayment,
as the case may be, as a convenience to Holders; provided, however, that any
such notice may state that no representation is made as to the correctness of
such numbers either as printed on the Securities or as contained

                                    21

<PAGE>

in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall
not be affected by any defect in or omission of such numbers.

                                   ARTICLE 3

                       Application of Available Cash Flow
                       ----------------------------------

          SECTION 3.01 General. (a) Except as expressly provided in this
                       -------
Indenture or the Securities, and subject to the provisions of Article 12 hereof,
all payments of the principal of, and accrued interest on, the Securities shall
be made solely out of Available Cash Flow of the Corporation in the manner and
to the extent provided below. Each Securityholder, by accepting a Security,
acknowledges and agrees to the limitations on payment of the Securities set
forth herein.

          (b) Not less than 5 days prior to each payment date on the Securities,
the Corporation shall furnish to the Trustee a statement containing a
calculation in reasonable detail of the Available Cash Flow with respect to such
payment date and setting forth (i) the amount of such Available Cash Flow to be
applied to the payment of the Senior Discount Notes in accordance with the Note
Purchase Agreement for Senior Discount Notes, (ii) the amount to be applied to
the payment of accrued interest on the Securities pursuant to Section 3.02(a),
(iii) the amount to be applied to the prepayment of principal of the Securities
pursuant to Section 3.03, and (iv) the amount of any additional Securities to be
issued in payment of accrued interest pursuant to Section 3.02(b).

          SECTION 3.02 Application of Available Cash Flow. (a) Subject to the
                       ----------------------------------
provisions of Article 12 hereof, on each payment date specified in the
Securities, the Corporation shall apply 100% of the Available Cash Flow received
by the Corporation during the semi-annual period ended on the December 31 or
June 30 next preceding such payment date (i) first to be the payment of all
amounts due the Trustee hereunder, and then (ii) to the payment of accrued
interest on the Securities (to the extent of such Available Cash Flow) and the
balance to the prepayment of principal pursuant to Section 3.03. Notwithstanding
the foregoing, the Corporation may retain an amount equal to 5% of Available
Cash Flow on each payment date to establish a working capital reserve (the
"Reserve"), until it has accumulated an aggregate of $2.5 million, and
thereafter 100% of such Available Cash Flow shall be applied in accordance with
this Section 3.02.

          (b) If Available Cash Flow (less the Reserve) on any payment date
would be insufficient to make such payment in full, the Corporation shall issue
additional Securities (valued at 100% of the principal amount thereof) in an
aggregate amount equal to the aggregate amount of interest otherwise payable in
cash on such date. Such additional Securities shall be issued in accordance with
Section 2.14 hereof.

          (c) If, and to the extent that, Available Cash Flow for any period
includes Net Available Cash attributable to an Asset Sale involving ADSC, the
provisions of Section 3.02 and Article 12 hereof and not of Section 5.05 shall
govern the application of such Net Available Cash by the Corporation.

                                       22

<PAGE>

          SECTION 3.03 Mandatory Prepayment. If, with respect to any payment
                       --------------------
date specified in the Securities, after application of Available Cash Flow as
provided in paragraph (a) of Section 3.02, there remains any balance (in excess
of $10,000) of such Available Cash Flow, subject to the provisions of Article 12
hereof, the Corporation shall apply such balance to the pro rata prepayment of
the outstanding principal of the Securities. The Trustee shall promptly notify
each Holder of any such prepayment of principal of the Securities held by such
Holder.

          SECTION 3.04 Obligation to Pay Securities in Cash at Maturity.
                       ------------------------------------------------
Notwithstanding anything contained in this Indenture or the Securities, subject
to the provisions of Article 12 hereof, the full amount of all interest accrued
on, and the principal amount of, the Securities shall be payable in cash without
regard to the source of such cash or the amount of Available Cash Flow on the
maturity date of the Securities, whether at the stated maturity on the Maturity
Date, or upon acceleration or otherwise.

                                   ARTICLE 4

                                   Redemption
                                   ----------

          SECTION 4.01 Notices to Trustee. If the Corporation elects to redeem
                       ------------------
Securities pursuant to paragraph 7 of the Securities, it shall notify the
Trustee in writing of the redemption date and the principal amount of Securities
to be redeemed.

          The Corporation shall give the notices provided for in this Section at
least 60 days before the redemption date, unless the Trustee consents to a
shorter period. Such notice shall be accompanied by an Officers' Certificate and
an Opinion of Counsel from the Corporation that such redemption will comply with
the conditions contained herein.

          If less than all the Securities are to be redeemed, the record date
relating to such redemption shall be selected by the Corporation and given by
notice to the Trustee, which record date shall be not less than 15 days after
the date of notice to the Trustee.

          SECTION 4.02 Selection of Securities To Be Redeemed. If less than all
                       --------------------------------------
the Securities are to be redeemed, the Trustee shall select the Securities to be
redeemed pro rata or by lot or by a method that complies with applicable legal
and securities exchange requirements, if any. The Trustee shall make the
selection from outstanding Securities not previously called for redemption. The
Trustee may select for redemption portions of the principal of Securities that
have denominations larger than $1,000, subject to the restriction that
Securities and portions of Securities the Trustee selects shall be in amounts of
$1,000 or a whole multiple of $1,000. Securities in denominations of $1,000 or
less may only be redeemed in whole. Provisions of this Indenture that apply to
Securities called for redemption also apply to portions of Securities called for
redemption. The Trustee shall notify the Corporation promptly of the Securities
or portions of Securities to be redeemed.

          SECTION 4.03 Notice of Redemption. At least 30 days but not more than
                       --------------------
60 days before a date for redemption of Securities, the Corporation shall mail a
notice of redemption by first-class mail to each Holder of Securities to be
redeemed.

          The notice shall identify the Securities to be redeemed and shall
state:

                                       23

<PAGE>

          (1) the redemption date;

          (2) the redemption price;

          (3) the name and address of the Paying Agent;

          (4) that Securities called for redemption must be surrendered to the
     Paying Agent to collect the redemption price;

          (5) if less than all the outstanding Securities are to be redeemed,
     the identification and principal amounts of the particular Securities to be
     redeemed;

          (6) that, unless the Corporation defaults in making such redemption
     payment, interest on Securities called for redemption ceases to accrue on
     and after the redemption date;

          (7) the paragraph of the Securities and/or Section of this Indenture
     pursuant to which the Securities called for redemption are being redeemed;
     and

          (8) the CUSIP number, provided that no representation is made as to
     the correctness or accuracy of the CUSIP number, if any, listed in such
     notice or printed on the Securities.

          At the Corporation's request, the Trustee shall give the notice of
redemption in the Corporation's name and at the Corporation's expense. In such
event the Corporation shall provide the Trustee with the information required by
clauses (1) through (4) and (7).

          SECTION 4.04 Effect of Notice of Redemption. Once notice of redemption
                       ------------------------------
is mailed, Securities called for redemption become due and payable on the
redemption date and at the redemption price stated in the notice. Upon surrender
to the Paying Agent, such Securities shall be paid at the redemption price
stated in the notice, plus accrued interest to the redemption date. Failure to
give notice or any defect in the notice to any Holder shall not affect the
validity of the notice to any other Holder.

          SECTION 4.05 Deposit of Redemption Price. Prior to 10:00 a.m. New York
                       ---------------------------
City time on the redemption date, the Corporation shall deposit with the Paying
Agent (or if the Corporation or a Subsidiary is the Paying Agent, shall
segregate and hold in trust) money, in immediately available funds, sufficient
to pay the redemption price of and accrued interest on all Securities to be
redeemed on that date other than Securities or portions of Securities called for
redemption which have been delivered by the Corporation to the Trustee for
cancellation.

          SECTION 4.06 Securities Redeemed in Part. Upon surrender to the
                       ---------------------------
Trustee at the Corporate Trust Office of a Security that is redeemed in part,
the Trustee shall authenticate for the Holder (at the Corporation's expense) a
new Security equal in principal amount to the unredeemed portion of the Security
surrendered.

                                    ---------

          SECTION 5.01 Payment of Securities. The Corporation shall promptly pay
                       ---------------------
the principal of and interest on the Securities not later than 11:00 a.m. New
York City time on the dates and in the manner provided in the Securities and in
this Indenture. Principal and interest (including any redemption price) shall be
considered paid on the date due if the Trustee or the Paying Agent (other than
the Corporation or a Subsidiary) holds on such date as of 11:00 a.m. New York
City time money in U.S. dollars sufficient to pay all principal and interest
(including any redemption price) then due and the Trustee or the Paying Agent is
not prohibited from paying such money to the Holders on that date pursuant to
the terms of this Indenture; provided, however, that, in the event of payment of
interest through the issuance of additional Securities as set forth in the
Securities, interest shall be considered paid on the date due if such additional
Securities are issued on that date.

          The Corporation shall pay interest on overdue principal (including any
redemption price) at the rate borne by the Securities plus 1% per annum, and it
shall pay interest on overdue installments of interest at the same rate to the
extent lawful.

          SECTION 5.02 SEC Reports. The Corporation shall file with the Trustee
                       -----------
within 15 days after it files them with the SEC copies of the annual report and
of the information, documents and other reports (or copies of such portions of
any of the foregoing as the SEC may by rules and regulations prescribe) which
the Corporation is required to file with the SEC pursuant to Section 13 or 15(d)
of the Securities Exchange Act of 1934. In the event the Corporation is at any
time no longer subject to the reporting requirements of Section 13 or 15(d) of
the Securities and Exchange Act of 1934, it shall continue to file with the SEC
and provide the Trustee with reports containing substantially the same
information as would have been required to be filed with the SEC with respect to
financial statements, management's discussion and analysis and a discussion of
significant changes in the business and financial condition of the Corporation
had the Corporation continued to have been subject to such reporting
requirements. In such event, such reports shall be provided at the times the
Corporation would have been required to provide reports had it continued to have
been subject to such reporting requirements. Subsequent to qualification of the
Indenture under the TIA, the Corporation also shall comply with the other
provisions of TIA Section 314(a).

          SECTION 5.03 Limitation on Indebtedness. (a) The Corporation shall
                       --------------------------
not, and shall not permit any of its Restricted Subsidiaries to, issue, assume,
guarantee, incur or otherwise become liable for (collectively, "Incur") any
Indebtedness; provided, however, that: (i) the Corporation may Incur
Indebtedness which is expressly subordinate and junior in right of payment to
the Notes; and (ii) the Corporation and its Restricted Subsidiaries may Incur
Indebtedness if, on the date of Incurrence, the Consolidated Coverage Ratio
would be at least equal to 3.00 to 1.00.

          (b) Notwithstanding the foregoing paragraph (a), the Corporation and
its Restricted Subsidiaries may Incur the following Indebtedness:

     Securities;

               (ii) Existing Indebtedness;

               (iii) Indebtedness owed by any Restricted Subsidiary to the
     Corporation or to another Restricted Subsidiary, or owed by the Corporation
     to any Restricted Subsidiary; provided, however, that any such Indebtedness
     shall be at all times held by a Person which is either the Corporation or a
     Restricted Subsidiary of the Corporation;

               (iv) Indebtedness of the Corporation or any Restricted Subsidiary
     arising with respect to Interest Rate Agreement Obligations and Currency
     Agreement Obligations Incurred for the purpose of fixing or hedging
     interest rate risk or currency risk;

               (v) Indebtedness represented by performance, completion,
     guarantee, surety and similar bonds provided by the Corporation or any
     Restricted Subsidiary in the ordinary course of business;

               (vi) Indebtedness Incurred by the Corporation or any of its
     Restricted Subsidiaries constituting reimbursement obligations with respect
     to letters of credit or other instruments issued in the ordinary course of
     business, including without limitation letters of credit in respect of
     workmen's compensation claims or self-insurance or securing obligations of
     the Corporation or any Restricted Subsidiary under operating leases;
     provided that upon drawing of such letters of credit or other instrument
     such drawings are reimbursed within 30 days following demand for
     reimbursements;

               (vii) Indebtedness Incurred in connection with or given in
     exchange for the renewal, extension, modification, amendment, refunding,
     defeasance, refinancing or replacement (a "refinancing") of any of the
     Securities or any Existing Indebtedness or any Indebtedness issued after
     the Issue Date and not Incurred in violation of the Indenture ("Refinancing
     Indebtedness"); provided, however, that (a) the principal amount of such
     Refinancing Indebtedness shall not exceed the principal amount (or accreted
     amount, if less) of the Indebtedness so refinanced at the time outstanding
     (or obtainable under any outstanding revolving credit or similar agreement)
     (plus the premiums paid in connection therewith and the reasonable expenses
     incurred in connection therewith), provided further, that in the case of a
     refinancing of Indebtedness under a revolving credit or similar agreement,
     if the agreement has been terminated prior to the date of such refinancing
     and all Indebtedness thereunder been repaid, the amount of such Refinancing
     Indebtedness shall not exceed the maximum amount obtainable under such
     agreement at the time of termination thereof; (b) with respect to
     Subordinated Indebtedness being refinanced, the Stated Maturity of the
     Refinancing Indebtedness shall be not earlier than the Stated Maturity of
     the Indebtedness being refinanced, and such Refinancing Indebtedness shall
     have an Average Life at the time such Refinancing Indebtedness is incurred
     that is equal to or greater than the remaining Average Life of the
     Indebtedness being Refinanced; (c) with respect to Subordinated
     Indebtedness of the Corporation being refinanced, such Refinancing
     Indebtedness shall rank no more senior than, and shall be at

                                       26

<PAGE>

     least as subordinated in right of payment to the Securities as the
     Indebtedness being refinanced; and (d) the obligor on such Refinancing
     Indebtedness shall be the obligor on the Indebtedness being refinanced or
     the Corporation or another Restricted Subsidiary;

               (viii) Indebtedness of the Corporation or any Restricted
     Subsidiary (a) representing Capital Lease Obligations and (b) in respect of
     Purchase Money Obligations for property acquired in the ordinary course of
     business, which taken together do not exceed $3 million in aggregate amount
     at any time outstanding;

               (ix) Indebtedness of Foreign Subsidiaries of the Corporation not
     to exceed a principal amount outstanding at any time of $5 million in the
     aggregate for all Foreign Subsidiaries; and

               (x) Guarantees by the Corporation or any Restricted Subsidiary of
     Indebtedness of the Corporation or any Restricted Subsidiary that was
     permitted to be Incurred pursuant to another provision of this covenant;

               (xi) Indebtedness of a Restricted Subsidiary engaged in providing
     lease or similar financing to customers of the Corporation or its
     Restricted Subsidiaries, not exceeding 7.5% of Consolidated Total Assets;

               (xii) Indebtedness of the Corporation or any Restricted
     Subsidiary Incurred pursuant to the Hillside Agreement, including without
     limitation any Guarantee of such Indebtedness Incurred pursuant to such
     Agreement; and

               (xiii) Indebtedness of the Corporation or any Restricted
     Subsidiary in addition to that described in clauses (i) through (xii)
     above, and any refinancings of such Indebtedness, so long as the aggregate
     principal amount of all such Indebtedness Incurred pursuant to this clause
     (xii) does not exceed at any time outstanding $15 million plus 75% of the
     amount by which accounts receivable (net of reserves) of the Corporation
     and its Restricted Subsidiaries (as shown in the Corporation's most recent
     consolidated balance sheet) exceeds $15 million.

          Any Indebtedness of a Person existing at the time such Person becomes
a Restricted Subsidiary (whether by merger, consolidation, acquisition or

Restricted Subsidiary at the time it becomes a Restricted Subsidiary.

          SECTION 5.04 Limitation on Restricted Payments. The Corporation will
                       ---------------------------------
not, and will not permit any Restricted Subsidiary to, directly or indirectly,
make any Restricted Payment (including any Restricted Investment), unless at the
time of and immediately after giving effect to the proposed Restricted Payment
(with the value of any such Restricted Payment, if other than cash, to be
determined reasonably and in good faith by the Board of Directors of the
Corporation), (i) no Default or Event of Default shall have occurred and be
continuing or would occur as a consequence thereof, (ii) the Corporation could
Incur at least $1.00 of additional Indebtedness pursuant to the first paragraph
under Section 5.03 and (iii) the aggregate amount of all Restricted Payments
made after the Issue Date shall not exceed the sum of (a) an amount equal to 50%
of the Corporation's aggregate cumulative Consolidated Net Income accrued on a

                                       27

<PAGE>

cumulative basis during the period (treated as one accounting period) beginning
on January 1, 1998 and ending on the last day of the fiscal quarter of the
Corporation immediately preceding the date of such proposed Restricted Payment
(or, if such aggregate cumulative Consolidated Net Income for such period shall
be a deficit, minus 100% of such deficit), plus (b) (x) the aggregate amount of
all Net Proceeds received since the Issue Date by the Corporation from the
issuance and sale (other than to a Restricted Subsidiary) of Capital Stock
(other than Disqualified Stock), and (y) an amount equal to the amount (as shown
on the Corporation's most recent consolidated balance sheet, prepared in
accordance with GAAP) of all Indebtedness or Disqualified Stock that, after the
Issue Date, is converted into or exchanged for Capital Stock of the Corporation
(other than Disqualified Stock) (less the amount of any cash or property
distributed by the Corporation upon such conversion or exchange), plus (c) the
amount of the net reduction in Investments by the Corporation or its Restricted
Subsidiaries in Unrestricted Subsidiaries resulting from (x) the payment of
dividends or the repayment in cash of the principal of loans or the net proceeds
from the sale of the Capital Stock or assets of such Unrestricted Subsidiaries
or other cash return on such Investment, in each case to the extent received by
the Corporation or any Restricted Subsidiary of the Corporation, (y) the release
or extinguishment of any guarantee of Indebtedness of any Unrestricted
Subsidiary, and (z) the redesignation of Unrestricted Subsidiaries as Restricted
Subsidiaries of the Corporation (valued as provided in the definition of
"Investment"), such aggregate amount of the net reduction in Investments not to
exceed the amount of Restricted Investments previously made by the Corporation
or any Restricted Subsidiary of the Corporation in such Unrestricted
Subsidiaries, which amount was included in the calculation of the amount of
Restricted Payments. For purposes of the foregoing clause (c), the Corporation
shall be deemed to have made a Restricted Investment under the Indenture in an
amount equal to any cash contribution made or subscribed for by the Corporation
on or immediately prior to the Issue Date to one or more Unrestricted
Subsidiaries.

          In addition, so long as there is no Default or Event of Default
continuing, the following payments and other actions shall be expressly
permitted notwithstanding anything contained in the covenant described above
(collectively, "Permitted Payments"):

               (i) the payment of any dividend within 60 days after the date of
     declaration thereof, if at such declaration date such payment would have
     been permitted under the Indenture and such payment shall be deemed to have
     been paid on such date of declaration for purposes of clause (iii) of the
     preceding paragraph;

               (ii) the redemption, repurchase, retirement or other acquisition
     of any Capital Stock or any Indebtedness of the Corporation that is

     Restricted Subsidiary) of Capital Stock of the Corporation (other than any
     Disqualified Stock);

               (iii) any purchase or defeasance of Subordinated Indebtedness to
     the extent required upon a Change of Control or Asset Sale (as defined
     herein) by this Indenture or other agreement or instrument pursuant to
     which such Subordinated Indebtedness was issued, but only if the
     Corporation (x) in the case of a Change of Control, has complied with its
     obligations under Section 5.10 or (y) in the case of an

                                    28

<PAGE>

     Asset Sale has applied the Net Available Cash from such Asset Sale in
     accordance with the provisions of Section 5.05 of this Indenture;

               (iv) any Restricted Investments made with the proceeds of the
     substantially concurrent sale of Capital Stock (other than Disqualified
     Stock);

               (v) Restricted Investments in any Unrestricted Subsidiary engaged
     in providing lease or similar financing to customers of the Corporation and

     after the Issue Date and outstanding on the date of determination does not
     exceed the greater of $5 million or 7.5% of Consolidated Total Assets;

               (vi) the repurchase of Capital Stock of the Corporation

     Corporation or its Subsidiaries pursuant to the terms of an employee
     benefit plan or employment agreement or similar arrangement; provided that
     an aggregate amount of all such repurchases (net of repayments or
     cancellations of indebtedness as a result of such repurchases) shall not
     exceed $1 million in any fiscal year;

               (vii) the redemption or repurchase of the Corporation's
     Noncumulative Redeemable Preferred Stock at a price not to exceed 100% of
     liquidation value; provided, however, that the aggregate amount of all
     payments pursuant to this clause (vii) shall not exceed 100% of cumulative
     Consolidated GAAP Net Income accrued during the period from January 1, 1998
     to the date of payment (treated as one accounting period); and

               (viii) Restricted Payments (other than a dividend or other
     distribution declared on any Capital Stock of the Corporation or a payment
     to purchase, redeem or otherwise acquire or retire for value any Capital
     Stock of the Corporation) not to exceed $1 million in the aggregate.

          For purposes of clause (iii) of the first paragraph of this covenant,
Permitted Payments made pursuant to clauses (i), (vi) and (vii) of the
immediately preceding paragraph shall be included (without duplication) as
Restricted Payments made since the Issue Date.

          SECTION 5.05 Limitation on Asset Sales. (a) The Corporation will not,
                       -------------------------
and will not permit any Restricted Subsidiary to, make any Asset Sale unless (i)
the Corporation or such Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the fair market
value of the assets or other property sold or disposed of in the Asset Sale and
(ii) at least 75% of such consideration consists of either cash or Cash
Equivalents, provided, however, that, at the option of the Corporation, clause
(ii) shall not be applicable to Asset Sales (or portions of Asset Sales) to the
extent the Corporation shall apply cash and Cash Equivalents available from
other sources to make any required Asset Sale Offer as if 75% of such
consideration had consisted of cash and Cash Equivalents.

                                       29

<PAGE>

          For the purposes of this covenant, the following will be deemed to be
cash: (x) the assumption by the transferee of Indebtedness of the Corporation or
Indebtedness of any Restricted Subsidiary of the Corporation and the release of
the Corporation or such Restricted Subsidiary from all liability on such
Indebtedness in connection with such Asset Sale (in which case the Corporation
shall, without further action, be deemed to have applied such assumed
Indebtedness in accordance with clause (A) of the preceding paragraph) and (y)
securities received by the Corporation or any Restricted Subsidiary of the
Corporation from the transferee that are promptly (and in any event within 120
days) converted by the Corporation or such Restricted Subsidiary into cash.

          (b) Subject to the provisions of Article 12 hereof, within 365 days
after any Asset Sale, the Corporation may elect to apply the Net Available Cash
from such Asset Sale to (i) permanently reduce or redeem any Senior Debt of the
Corporation or a Restricted Subsidiary and/or (ii) make an Investment in, or
acquire assets and properties that will be used in the business of the
Corporation and its Restricted Subsidiaries, and (iii) any balance of such Net
Available Cash exceeding $10 million and not applied or invested as provided in
clauses(i) and (ii) within 365 days of such Asset Sale, will be deemed to
constitute "Excess Proceeds" and shall be applied to make an offer to purchase
Securities to the holders of the Securities. Pending the final application of
any such Net Available Cash, the Corporation may temporarily invest such Net
Available Cash in cash or Cash Equivalents.

          (c) In the event of an Asset Sale that requires the purchase of
Securities pursuant to clause (b)(iii) above, the Corporation will be required
to purchase Securities tendered pursuant to an offer by the Corporation for the
Securities (the "Offer") at a purchase price of 100% of their principal amount
plus accrued and unpaid interest, if any, to the purchase date in accordance
with the procedures (including prorating in the event of oversubscription) set
forth in Section 5.05(d) below. If the aggregate purchase price of the
Securities tendered pursuant to the Offer is less than the Net Available Cash
allotted to the purchase of the Securities, the Corporation will apply the
remaining Net Available Cash to general corporate purposes not prohibited by
this Indenture. Upon the consummation of any Asset Sale Offer, the amount of
Excess Proceeds shall be deemed to be reset to zero.

          (d) (1) Promptly, and in any event within 10 days after the
Corporation becomes obligated to make an offer, the Corporation shall be
obligated to deliver to the Trustee and send, by first-class mail to each
Holder, a written notice stating that the Holder may elect to have his
Securities purchased by the Corporation either in whole or in part (subject to
the prorationing as hereinafter described in the event the Offer is
oversubscribed) in integral multiples of $1,000 of principal amount, at the
applicable purchase price. The notice shall specify a purchase date of not less
than 30 days nor more than 60 days after the date of such notice (the "Purchase
Date") and shall contain such information concerning the business of the
Corporation which the Corporation in good faith believes will enable such
Holders to make an informed decision (which at a minimum will include (1) the
most recently filed Annual report on 10-K (including audited consolidated
financial statements) of the Corporation, the most recent subsequently filed
Quarterly Report on Form 10-Q and any Current Report on Form 8-K of the
Corporation filed subsequent to such Quarterly report, other than Current
Reports describing Asset Sale otherwise described in the offering materials (or
corresponding successor reports), (ii) a description of material developments in
the Corporation's business subsequent to the date of

                                       30

<PAGE>

the latest of such reports, and (iii) if material, appropriate pro forma
financial information and all instructions and materials necessary to tender
Securities pursuant to the Offer, together with the information contained in
clause (3).

               (2) Not later than the date upon which the written notice of an
Offer is delivered to the Trustee as provided below, the Corporation shall
deliver to the Trustee an Officers' Certificate as to (i) the amount of the
Offer (the "Offer Amount"), (ii) the allocation of the Net Available Cash from
the Asset Sale pursuant to which such Offer is being made and (iii) the
compliance of such allocation with the provisions of Section 5.05(a). On such
date, the Corporation shall also irrevocably deposit with the Trustee or with a
paying agent (or, if the Corporation is acting as its own paying agent,
segregate and hold in trust) in cash or Cash Equivalents maturing on the day
prior to the Purchase Date or on the Purchase Date if funds are immediately
available by open of business an amount equal to the Offer Amount to be held for
payment in accordance with the provisions of this Section. Upon the expiration
of the period for which the Offer remains open (the "Offer Period"), the
Corporation shall deliver to the Trustee or the Paying Agent for cancellation
the Securities or portions thereof which have been properly tendered to and are
to be accepted by the Corporation. The Trustee shall, on the Purchase date, mail
or deliver payment to each tendering Holder in the amount of the purchase price.
In the event that the aggregate purchase price of the Securities delivered by
the Corporation to the Trustee is less than the Offer Amount, the Trustee shall
deliver the excess to the Corporation immediately after the expiration of the
Offer Period for application in accordance with this Section.

               (3) Holders electing to have a Security purchased will be
required to surrender the Security, with an appropriate form duly completed, to
the Corporation at the address specified in the notice at least three Business
Days prior to the Purchase Date. Holders will be entitled to withdraw their
election if the Trustee or the Corporation receives not later than one Business
day prior to the Purchase Date, a telegram, telex, facsimile transmission or
letter setting forth the name of the Holder, the principal amount of the
Security which was delivered for purchase by the Holder and a statement that
such Holder is withdrawing his election to have such Security purchased. If at
the expiration of the Offer Period the aggregate principal amount of Securities
surrendered by Holders exceeds the Offer Amount, the Corporation shall select
the Notes to be purchased on a pro rata basis (with such adjustments as may be
deemed appropriate by the Corporation so that only Securities in denominations
of $1,000 or integral multiples thereof, shall be purchased). Holders whose
Securities are purchased only in part will be issued new Securities equal in
principal amount to the unpurchased portion of the Securities surrendered.

               (4) At the time the Corporation delivers Securities to the
Trustee which are to be accepted for the purchase, the Corporation will also
deliver an Officers' Certificate stating that such Securities are to accepted by
the Corporation pursuant to and in accordance with the terms of this Section. A
Security shall be deemed to have been accepted for purchase at the time the
Trustee, directly or through an agent, mails or delivers payment therefor to the
surrendering Holder.

          (e) The Corporation will comply, to the extent applicable, with the
requirements of Section 14 (e) of the Exchange Act and any other applicable
securities laws or

                                       31

regulations in connection with the repurchase of Securities pursuant to this
Indenture and will not be deemed to have breached its obligations under this
Indenture by virtue thereof.

          SECTION 5.06 Limitation on Liens. The Corporation will not, and will
                       -------------------
not permit any Restricted Subsidiary to, directly or indirectly, Incur or suffer
to exist any Lien securing any Indebtedness (other than (1) Indebtedness under
this Indenture and Indebtedness described in paragraphs (a)(ii) and (b)(ii),
(vi), (vii)(to the extent the Refinanced Indebtedness was secured by a Lien
permitted by this Indenture), (xi), (xii) and (xiii) of the provisions of
Section 5.03 of this Indenture; and (2) Indebtedness of an Acquired Person
existing at the date such Person became a Restricted Subsidiary, and any
refinancing thereof, provided however, that such Lien is not applicable to any
Person or the properties or assets of any Person, other than the Acquired Person
) on any asset now owned or hereafter acquired unless the Securities are equally
and ratably secured thereby.

          SECTION 5.07 Limitation on Dividends and Other Payment Restrictions
                       ------------------------------------------------------
Affecting Restricted Subsidiaries. The Corporation will not, and will not permit
---------------------------------
any Restricted Subsidiary to, directly or indirectly, create or otherwise cause
or suffer to exist or become effective any consensual encumbrance or restriction
on the ability of any Restricted Subsidiary to (i) pay dividends or make any
other distributions to the Corporation or any other Restricted Subsidiary on its
Capital Stock, or pay any Indebtedness owed to the Corporation or any other
Restricted Subsidiary, make loans or advances to the Corporation or any other
Restricted Subsidiary or (iii) transfer any of its properties or assets to the
Corporation or any other Restricted Subsidiary, except for such encumbrances or
restrictions existing under or by reason of

          (1) any agreement or instrument evidencing or governing any Existing
     Indebtedness and any refinancings thereof;

          (2) applicable law;

          (3) any instrument governing Indebtedness or Capital Stock of an
     Acquired Person acquired by the Corporation or any of its Restricted
     Subsidiaries as in effect at the time of such acquisition or any
     refinancing thereof; provided, however, that such restriction is not
     applicable to any Person, or the properties or assets of any Person, other
     than the Acquired Person;

          (4) by reason of customary non-assignment provisions in leases entered
     into in the ordinary course of business and consistent with past practices;

          (5) Purchase Money Indebtedness for property acquired in the ordinary
     course of business that only impose restrictions on the property so
     acquired;

          (6) an agreement for the sale or disposition of the Capital Stock or
     assets of such Restricted Subsidiary; provided, however, that such
     restriction is only applicable to such Restricted Subsidiary or assets, as
     applicable, and such sale or disposition otherwise is permitted under
     Section 5.05 of this Indenture;

                                     32

<PAGE>

          (7) Refinancing Indebtedness permitted under the Indenture; provided,
     however, that the restrictions contained in the agreements governing such
     Refinancing Indebtedness are not materially more restrictive in the
     aggregate than those contained in the agreements governing the Indebtedness
     being refinanced immediately prior to such refinancing;

          (8) the Indenture and the Securities; arising or agreed to in the
     ordinary course of business, not relating to any Indebtedness, and that do
     not, individually or in the aggregate, detract from the value of property
     or assets of the Corporation or any Restricted Subsidiary in any manner
     material to the Corporation or any Restricted Subsidiary; or

          (9) any instrument governing Indebtedness of a Foreign Subsidiary
     which is permitted by the terms of the Indenture.

          Nothing contained in this Section 5.07 shall prevent the Corporation
or any Restricted Subsidiary from (1) creating, incurring, assuming or suffering
to exist any Liens otherwise permitted in the Section 5.06 covenant or (2)
restricting the sale or other disposition of property or assets of the
Corporation or any of its Restricted Subsidiaries that secure Indebtedness of
the Corporation or any of its Restricted Subsidiaries.

          SECTION 5.08 Limitation on Transactions with Affiliates. The
                       ------------------------------------------
Corporation will not, and will not permit any Restricted Subsidiary to, directly
or indirectly, enter into any transaction or series of related transactions
(including, without limitation, the sale, purchase, exchange or lease of assets,
property or services) with any Affiliate of the Corporation (other than the
Corporation or a Restricted Subsidiary) unless (1) such transaction or series of
transactions is on terms that are not materially less favorable to the
Corporation or such Restricted Subsidiary, as the case may be, than would be
available in a comparable transaction in arm's-length dealings with an unrelated
third party, and (2) the Corporation delivers to the Trustee, with respect to
any transaction or series of related transactions involving aggregate payments
in excess of $5.0 million, an Officers' Certificate certifying that such
transaction or series of related transactions has been approved by a majority of
the members of the Board of Directors of the Corporation and evidenced by a
resolution of the Board of Directors set forth in an Officers' Certificate.
Notwithstanding the foregoing, this covenant will not apply to

               (i) employment agreements, compensation or employee benefit
     arrangements, stock options or stock purchase plans or agreements with or
     for the benefit of any officer, director or employee of the Corporation

     of Directors of the Corporation (including loans and stock repurchase
     arrangements thereunder, customary fringe benefits and including
     reimbursement or advancement of out of pocket expenses, loans to officers,
     directors and employees in the ordinary course of business, reasonable fees
     paid to directors who are not employees of the Corporation, and director's

     receivable or inventory to one or more Unrestricted Subsidiaries engaged in
     financing receivables for the benefit of the Corporation or in providing
     lease or similar financing to customers of the Corporation;

               (iv) any Restricted Payment not prohibited by the provisions of
     Section 5.04 of this Indenture;

               (v) transactions permitted by, and complying with, the provisions
     of Section 6.01 of this Indenture;

               (vi) any sale or issuance of Capital Stock (other than
     Disqualified Stock) of the Corporation;

               (vii) the grant or performance of registration rights with
     respect to securities of the Corporation;

               (viii) transactions under and pursuant to the Sherborne
     Agreement; and

               (ix) transactions in which the Corporation or any of its
     Restricted Subsidiaries delivers to the Trustee an opinion from an
     independent nationally recognized financial advisor stating that such
     transaction is fair to the Corporation or such Restricted Subsidiary from a
     financial point of view and meets the requirements of clauses (1) and (2)
     above.

          SECTION 5.09 Limitation on Designation of Unrestricted Subsidiaries.
                       ------------------------------------------------------
The Corporation will not designate any Subsidiary of the Corporation (other than
a newly created Subsidiary in which no Investment in excess of $1,000 has
previously been made) as an "Unrestricted Subsidiary" under the Indenture (a
"Designation") after the Issue Date unless:

          (a) no Default shall have occurred and be continued at the time of or
     after giving effect to such Designation; and

          (b) the Corporation would not be prohibited under the Indenture from
     making an Investment at the time of Designation in an amount (the
     "Designation Amount") equal to the fair market value of such Restricted
     Subsidiary on such date.

          In the event of any such Designation, the Corporation shall be deemed
to have made an Investment constituting a Restricted Payment pursuant to the
provisions of Section 5.04 of this Indenture for all purposes of the Indenture
in the Designation Amount. Neither the Corporation nor any Restricted Subsidiary
shall at any time (x) provide a Guarantee of or similar undertaking (including
any undertaking, agreement or instrument evidencing such Indebtedness)with
respect to any Indebtedness of an Unrestricted Subsidiary; provided that the
Corporation and its Restricted Subsidiaries may pledge Capital Stock or
Indebtedness of any Unrestricted Subsidiary on a nonrecourse basis such that the
pledgee has no claim whatsoever against the Corporation other than to obtain
such pledged property or (y) be directly or indirectly liable for any
Indebtedness of any Unrestricted Subsidiary, except to the extent permitted
under the provisions of Section 5.04 of this Indenture.

                                       34

<PAGE>

          The Corporation may not revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation"), unless:

          (c) no Default shall have occurred and be continuing at the time of
     and after giving effect to such Revocation; and

          (d) all Liens and Indebtedness of such Unrestricted Subsidiary
     outstanding immediately following such Revocation shall be deemed to have
     been incurred at such time and shall have been permitted to be incurred for
     all purposes of the Indenture.

          All Designations and Revocations must be evidenced by Board
Resolutions delivered to the Trustee certifying compliance with the foregoing
provisions.

          SECTION 5.10 Change of Control. (a) Upon a Change of Control, each
                       -----------------
Holder shall have the right to require that the Corporation repurchase such
Holder's Securities at a purchase price in cash equal to 101% of the principal
amount thereof plus accrued and unpaid interest, if any, to the date of purchase
(subject to the right of Holders of record on a record date to receive interest
on the relevant payment date), in accordance with the terms contemplated in
Section 5.10(b).

          (b) Within 30 days following any Change of Control, the Corporation
shall mail a notice to each Holder with a copy to the Trustee stating:

          (1) that a Change of Control has occurred and that such Holder has the
     right to require the Corporation to purchase such Holder's Securities at a
     purchase price in cash equal to 101% of the principal amount thereof plus
     accrued and unpaid interest, if any, to the date of purchase (subject to
     the right of Holders of record on a record date to receive interest on the
     relevant payment date);

          (2) the repurchase date (which shall be no earlier than 30 days nor
     later than 60 days from the date such notice is mailed); and

          (3) the procedures determined by the Corporation, consistent with this
     Section, that a Holder must follow in order to have its Securities
     purchased.

          (c) Holders electing to have a Note purchased will be required to
surrender the Security, with an appropriate form duly completed, to the
Corporation at the address specified in the notice at least three Business Days
prior to the purchase date. Holders will be entitled to withdraw their election
if the Trustee or the Corporation receives not later than three Business Days
prior to the purchase date, a telegram, telex, facsimile transmission or letter
setting forth the name of the Holder, the principal amount of the Security which
was delivered for purchase by the Holder and a statement that such Holder is
withdrawing his election to have such Security purchased.

          (d) On the purchase date, all Securities to be purchased by the
Corporation under this Section shall be delivered to the Trustee for
cancellation, and the Corporation shall pay the purchase price plus accrued and
unpaid interest, if any, to the Holders entitled thereto.

                                       35

          (e) The Corporation shall 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 Securities pursuant to this
Section. To the extent that the provisions of any securities laws or regulations
conflict with provisions of this Section, the Corporation shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Section by virtue thereof.

          SECTION 5.11 Compliance Certificate; Notice of Defaults. The
                       ------------------------------------------
Corporation shall deliver to the Trustee within 120 days after the end of each
fiscal year of the Corporation an Officers' Certificate stating that in the
course of the performance by the signers of such Certificate of their duties as
Officers of the Corporation they would normally have knowledge of any Default by
the Corporation and whether or not the signers know of any Default or Event of
Default that occurred during such period. If they do know of such a Default or
Event of Default, the certificate shall describe the Default or Event of
Default, its status and what action the Corporation is taking or proposes to
take with respect thereto.

          Promptly after an Officer of the Corporation obtains knowledge of a
Default or Event of Default under this Indenture, the Corporation will deliver
to the Trustee an Officers' Certificate specifying such Default or Event of
Default and what action the Corporation is taking or proposes to take with
respect thereto.

          SECTION 5.12 Further Instruments and Acts. The Corporation will, upon
                       ----------------------------
request of the Trustee, execute and deliver such further instruments and do such
further acts as may be reasonably necessary or proper to carry out more
effectively the purposes of this Indenture.

     not the Corporation) shall assume by supplemental indenture all the
     obligations of the Corporation under the Securities and this Indenture;

     Default shall have happened and be continuing;

     with this Indenture. The Trustee shall be entitled to rely conclusively
     upon such Officers' Certificate and Opinion of Counsel.

          SECTION 7.01 Events of Default. An "Event of Default" occurs if:
                       -----------------

          (1) the Corporation defaults in the payment of interest on any
     Security when the same becomes due and payable, and such default continues
     for a period of 30 days;

          (2) the Corporation (i) defaults in the payment of the principal of

     hereof and in the Security Agreement and the Default continues for a period

     days after the notice specified below;

          (6) a default or event of default (as such term is defined in the
     instrument or agreement under which any Indebtedness is issued) occurs
     under any instrument under which there may be issued or by which there may
     be secured or evidenced any Indebtedness of the Corporation or any
     Significant Subsidiary (other than Indebtedness of a Restricted Subsidiary
     incurred pursuant to Section 5.03) and the holders of such Indebtedness
     have accelerated such Indebtedness or any default occurs in the payment of
     the principal amount of such Indebtedness at final maturity if the total of
     all such

                                    37

<PAGE>

     Indebtedness which has been so accelerated and all such Indebtedness which
     is overdue shall exceed $5,000,000 or its foreign currency equivalent at
     the time, and there shall have been a failure to obtain rescission or
     annulment of all such accelerations or to pay in full the amount in default
     (together with any applicable interest) by the later of the expiration of
     any applicable grace period or 10 days after the notice specified below;

          (7) any judgment or decree for the payment of money in excess of $5.0
     million or its foreign currency equivalent at the time is entered against
     the Corporation or any Significant Subsidiary, remains outstanding for a
     period of 60 days after the entry of such judgment or decree and is not
     discharged, waived or the execution thereof stayed within 10 days after the
     notice specified below;

          (8) the Corporation or any Significant Subsidiary pursuant to or
     within the meaning of any Bankruptcy Law:

               (A) commences a voluntary case;

               (B) consents to the entry of an order for relief against it in an
          involuntary case;

               (C) consents to the appointment of a Custodian of it or for any

               (D) makes a general assignment for the benefit of its creditors;
          or takes any comparable action under any foreign laws relating to
          insolvency; or

          (9) a court of competent jurisdiction enters an order or decree under
     any Bankruptcy Law that:

               (A) is for relief against the Corporation or any Significant
          Subsidiary in an involuntary case;

               (B) appoints a Custodian of the Corporation or any Significant
          Subsidiary or for any substantial part of its property; or

               (C) orders the winding up or liquidation of the Corporation or
          any Significant Subsidiary;

or any similar relief is granted under any foreign laws; and the order or decree
remains unstayed and in effect for 60 days.

          The term "Bankruptcy Law" means Title 11, United States Code, or any
similar Federal or state law for the relief of debtors. The term "Custodian"
means any receiver, trustee, assignee, liquidator, custodian or similar official
under any Bankruptcy Law.

          A Default under clause (5), (6) or (7) is not an Event of Default
until the Trustee or the Holders of at least 25% in principal amount of the
Securities notify the Corporation of the Default and the Corporation does not
cure such Default within the time specified after receipt of

                                       38

<PAGE>

such notice. Such notice must specify the Default, demand that it be remedied
and state that such notice is a "Notice of Default".

          The Corporation shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any event which with the giving of notice and the lapse of time would become an
Event of Default under clause (1), (2), (3), (4), (5), (6) or (7) hereof, its
status and what action the Corporation is taking or proposes to take with
respect thereto.

          The Trustee shall not be charged with knowledge of any Default or
Event of Default unless written notice thereof shall have been given to a Trust
Officer at the Corporate Trust Office of the Trustee by the Corporation or any
other Person.

          SECTION 7.02 Acceleration. If an Event of Default (other than an Event
                       ------------
of Default specified in Section 7.01(8) or (9) with respect to the Corporation)
occurs and is continuing, the Trustee by notice to the Corporation, or the
Holders of at least 25% in principal amount of the Securities by notice to the
Corporation and the Trustee may declare the principal of and accrued interest on
all the Securities to be due and payable. Upon such a declaration, such
principal and interest shall be due and payable immediately. If an Event of
Default specified in Section 7.01(8) or (9) with respect to the Corporation
occurs, the principal of and all accrued interest on the Securities shall ipso
facto become immediately due and payable without any declaration or other action
on the part of the Trustee or any Securityholders. The Holders of a majority in
principal amount of the Securities by notice to the Trustee may rescind an
acceleration and its consequences if the rescission would not conflict with any
judgment or decree and if all existing Events of Default have been cured or
waived except nonpayment of principal or interest that has become due solely
because of acceleration. No such rescission shall affect any subsequent Default
or Event of Default or impair any right consequent thereto.

          SECTION 7.03 Other Remedies. If an Event of Default occurs and is
                       --------------
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture or of the Security Agreement.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

          SECTION 7.04 Waiver of Past Defaults. The Holders of a majority in
                       -----------------------
principal amount of the Securities by notice to the Trustee may waive an
existing Default or Event of Default and its consequences except (i) a Default
in the payment of the principal or interest on a Security or (ii) a Default in
respect of a provision that under Section 10.02 cannot be amended without the
consent of the Securityholders affected. When a Default is waived, it is deemed
cured, but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any consequent right.

                                       39

<PAGE>

          SECTION 7.05 Control by Majority. The Holders of a majority in
                       -------------------
principal amount of the Securities may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on it. However, the Trustee may refuse
to follow any direction that conflicts with law or this Indenture or, subject to
Section 8.01, that the Trustee determines is unduly prejudicial to the rights of
other Securityholders or would involve the Trustee in personal liability;
provided, however, that the Trustee may take any other action deemed proper by
the Trustee that is not inconsistent with such direction. Prior to taking any
action hereunder, the Trustee shall be entitled to indemnification satisfactory
to it in its sole discretion against all losses and expenses caused by taking or
not taking such action.

          SECTION 7.06 Limitation on Suits. A Securityholder may not pursue any
                       -------------------
remedy with respect to this Indenture or the Securities unless:

          (1) the Holder gives to the Trustee written notice stating that an
     Event of Default is continuing;

          (2) the Holders of at least 25% in principal amount of the Securities
     make a written request to the Trustee to pursue the remedy;

          (3) such Holder or Holders offer and, if requested, provide to the
     Trustee reasonable security or indemnity against any loss, liability or
     expense;

          (4) the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer and, if requested, provision of
     security or indemnity; and

          (5) the Trustee has not received from the Holders of a majority of
     principal amount of the Securities a direction inconsistent with the
     request during such 60-day period.

          A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over another
Securityholder.

          SECTION 7.07 Rights of Holders To Receive Payment. Notwithstanding any
                       ------------------------------------
other provision of this Indenture, the right of any Holder to receive payment of
principal of and interest on the Securities held by such Holder, on or after the
respective due dates expressed in the Securities, or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

          SECTION 7.08 Collection Suit by Trustee. If an Event of Default in
                       --------------------------
payment of interest or principal specified in Section 7.01(1) or (2) occurs and
is continuing, the Trustee may recover judgment in its own name and as trustee
of an express trust against the Corporation for the whole amount of principal
and interest remaining unpaid and the amounts provided for in Section 8.07.

          SECTION 7.09 Trustee May File Proofs of Claim. Subject to Section
                       --------------------------------
7.05, the Trustee may file such proofs of claim and other papers or documents
and take other action including participating as a member (voting or otherwise)
of any committee of creditors

                                       40

<PAGE>

appointed in the matter as may be necessary or advisable in order to have the
claims of the Trustee and the Securityholders allowed in any judicial
proceedings relative to the Corporation, its creditors or its property and,
unless prohibited by law or applicable regulations, may vote on behalf of the
Holders in any election of a trustee in bankruptcy or other person performing
similar functions, and any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make payments to the Trustee and, in the event that
the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due it for the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due
the Trustee under Section 8.07.

          SECTION 7.10 Priorities. If the Trustee collects any money pursuant to
                       ----------
this Article, it shall pay out the money in the following order:

          FIRST: to the Trustee for amounts due under Section 8.07;

          SECOND: to Securityholders for amounts due and unpaid on the
          Securities for principal and interest, ratably, without preference or
          priority of any kind, according to the amounts due and payable on the
          Securities for principal and interest, respectively; and

          THIRD: to the Corporation.

          The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section. At least 15 days before such record
date, the Corporation shall mail to each Securityholder and the Trustee a notice
that states the record date, the payment date and amount to be paid.

          SECTION 7.11 Undertaking for Costs. In any suit for the enforcement of
                       ---------------------
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section does not apply to a suit by the
Trustee, a suit by a Holder pursuant to Section 7.07 or a suit by Holders of
more than 10% in principal amount of the Securities.

          SECTION 7.12 Waiver of Stay or Extension Laws. The Corporation (to the
                       --------------------------------
extent it may lawfully do so) shall not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Corporation
(to the extent that it may lawfully do so) hereby expressly waives all benefit
or advantage of any such law; and shall not hinder, delay or impede the
execution of any power herein granted to the Trustee, but shall suffer and
permit the execution of every such power as though no such law had been enacted.

          SECTION 8.01 Duties of Trustee. (a) If an Event of Default has
                       -----------------
occurred and is continuing, the Trustee shall exercise its rights and powers and
use the same degree of care and skill in its exercise as a prudent person would
exercise or use in the circumstances in the conduct of such person's own
affairs.

          (b) Except during the continuance of an Event of Default known to the
Trustee:

          (1) the duties of the Trustee shall be determined solely by the
     express provisions of this Indenture and the Trustee need perform only
     those duties that are specifically set forth in this Indenture and no
     others and no implied covenants or obligations shall be read into this
     Indenture; and

          (2) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. However,
     the Trustee shall examine the certificates and opinions to determine
     whether or not they conform to the requirements of this Indenture.

          (c) The Trustee shall not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

          (1) this paragraph does not limit the effect of paragraph (b) of this
     Section;

          (2) the Trustee shall not be liable for any error of judgment made in
     good faith by a Trust Officer unless it is proved that the Trustee was
     negligent in ascertaining the pertinent facts; and

          (3) the Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction in

receives written notice of or has actual knowledge thereof.

          (h) No provision of this Indenture or the Security Agreement shall
require the Trustee to expend or risk its own funds or otherwise incur financial
liability in the performance of any of its duties hereunder or in the exercise
of any rights or powers if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risks or liabilities
is not reasonably assured to it.

          (i) Every provision of the Indenture relating to the conduct or
affecting the liability or affording protection to the Trustee shall be subject
to the provisions of this Section and to the applicable provisions of the TIA.

          SECTION 8.02 Rights of Trustee. (a) The Trustee may conclusively rely
                       -----------------

powers provided that the Trustee's conduct does not constitute negligence or bad
faith.

demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer.

          SECTION 8.03 Individual Rights of Trustee. The Trustee in its

individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Corporation or its Affiliates with the same
rights it would have if it were not Trustee. However, if the Trustee acquires
any conflicting interest it must eliminate such conflict within 90 days, apply
to the Commission for permission to continue as Trustee or resign. Any Paying
Agent, Registrar or co-registrar may do the same with like rights. However, the
Trustee must comply with Sections 8.10 and 8.11.

Securities or in the Securities other than the Trustee's certificate of
authentication.

          SECTION 8.05 Notice of Default. If a Default or an Event of Default
                       -----------------
occurs and is continuing and the Trustee has knowledge of such event, the
Trustee shall mail to each Securityholder notice of the Default or Event of
Default within 90 days after the occurrence thereof, unless such Default or
Event of Default has been cured. Except in the case of a Default in payment of
principal of or interest on any Security, the Trustee may withhold the notice if
and as long as a committee of its Trust Officers in good faith determines that
withholding the notice is in the interests of Securityholders.

          SECTION 8.06 Reports by Trustee to Holders. Within 60 days after each
                       -----------------------------
May 15 beginning with the May 15 following the date of this Indenture, the
Trustee if required by TIA Section 313(a) shall mail to each Securityholder a
brief report dated as of May 15 that complies with TIA Section 313(a). The
Trustee also shall comply with TIA Section 313(b).

          A copy of each report at the time of its mailing to Securityholders
shall be filed with the SEC and each stock exchange on which the Securities are
listed. The Corporation agrees promptly to notify the Trustee whenever the
Securities become listed on any stock exchange and of any delisting thereof.

          SECTION 8.07 Compensation and Indemnity. The Corporation shall pay to
                       --------------------------
the Trustee from time to time reasonable compensation for its services. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Corporation shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it in
addition to the compensation for its services. Such expenses shall include the
reasonable compensation and expenses, disbursements and advances of the
Trustee's agents and counsel. The Corporation shall indemnify the Trustee
against any and all loss, liability or expense (including attorneys' fees)
incurred by it without negligence or bad faith on its part in connection with
the administration of this trust and the performance of its duties hereunder.
The Trustee shall promptly notify the Corporation promptly of any claim for
which it may seek indemnity. Failure by the Trustee to so notify the Corporation
shall not relieve the Corporation of its obligations hereunder. The Corporation
shall defend the claim and the Trustee may have separate counsel and the
Corporation shall pay the fees and expenses of such counsel. The Corporation
need not reimburse any expense or indemnify against any loss or liability
incurred by the Trustee through negligence or bad faith.

          To secure the Corporation's payment obligations in this Section, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee, except that held in trust to pay principal of and
interest on particular Securities. Such Lien shall survive the satisfaction and
discharge of this Indenture.

          The Corporation's payment obligations pursuant to this Section shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of an Event of Default specified in subsection 7.01(6) or (7),
the expenses are intended to constitute expenses of administration under the
Bankruptcy Law.

          SECTION 8.08 Replacement of Trustee. The Trustee may resign at any
                       ----------------------
time by so notifying the Corporation. The Holders of a majority in principal
amount of the Securities

                                       44

<PAGE>

may remove the Trustee by so notifying the Trustee in writing and may appoint a
successor Trustee. The Corporation may remove the Trustee if:

          (1) the Trustee fails to comply with Section 8.10;

          (2) the Trustee is adjudged a bankrupt or insolvent;

          (3) a receiver or other public officer takes charge of the Trustee or
     its property; or

          (4) the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason (the Trustee in such event being referred to
herein as the retiring trustee) the Corporation shall promptly appoint a
successor Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Corporation. Immediately after
receiving such acceptance, the retiring Trustee shall transfer all property held
by it as Trustee to the successor Trustee, subject to the lien provided for in
Section 8.07, the resignation or removal of the retiring Trustee shall then
become effective, and the successor Trustee shall have all the rights, powers
and duties of the Trustee under this Indenture. A successor Trustee shall mail
notice of its succession to each Securityholder.

          If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Corporation or
the Holders of a majority in principal amount of the Securities may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

          If the Trustee fails to comply with Section 8.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

          SECTION 8.09 Successor Trustee by Merger. If the Trustee consolidates
                       ---------------------------
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

          In case at the time such successor or successors by merger, conversion
or consolidation to the Trustee shall succeed to the trusts created by this
Indenture any of the Securities shall have been authenticated but not delivered,
any such successor to the Trustee may adopt the certificate of authentication of
any predecessor trustee, and deliver such Securities so authenticated; and in
case at that time any of the Securities shall not have been authenticated, any
successor to the Trustee may authenticate such Securities either in the name of
any predecessor hereunder or in the name of the successor to the Trustee; and in
all such cases such certificates shall have the full force which it is anywhere
in the Securities or in this Indenture provided that the certificate of the
Trustee shall have.

          SECTION 8.10 Eligibility; Disqualification. The Trustee shall at all
                       -----------------------------

times satisfy the requirements of TIA Section 310(a)(1). The Trustee shall have
a combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
Section 310(b), including the optional provision permitted by the second
sentence of TIA Section 310(b)(9); provided, however, that there shall be
excluded from the operation of TIA Section 310(b)(2) any indenture or indentures
under which other securities or certificates of interest or participation in
other securities of the Corporation are outstanding if the requirement for such
exclusions set forth in TIA Section 310(b)(1) are met.

          SECTION 8.11 Preferential Collection of Claims Against Corporation.
                       -----------------------------------------------------
The Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated.

                                   ARTICLE 9

                     Satisfaction and Discharge of Indenture
                     ---------------------------------------

          SECTION 9.01 Discharge of Liability on Securities; Defeasance. (a)
                       ------------------------------------------------
When (i) the Corporation delivers to the Trustee all outstanding Securities
(other than Securities replaced pursuant to Section 2.10) for cancellation or
(ii) all outstanding Securities have become due and payable and the Corporation
irrevocably deposits with the Trustee funds sufficient to pay at maturity or
upon redemption all outstanding Securities including interest thereon if any
(other than Securities replaced pursuant to Section 2.10), and if in either case
the Corporation pays all other sums payable hereunder by the Corporation, then
this Indenture shall, subject to Sections 9.01(c) and 9.06, cease to be of
further effect. Upon satisfaction of the conditions set forth herein and upon
the Corporation's request (and at the Corporation's expense), the Trustee shall
acknowledge satisfaction and discharge of this Indenture on demand of the
Corporation accompanied by an Officers' Certificate and an Opinion of Counsel
and at the cost and expense of the Corporation.

          (b) Subject to Sections 9.01(c), 9.02 and 9.06, the Corporation at any
time may terminate (i) all its obligations under the Securities and this
Indenture ("legal defeasance option") or (ii) its obligations under Sections
5.02 through 5.12 and Section 6.01(a)(iii) and the operation of Sections
7.01(3), 7.01(4), 7.01(5), 7.01(6) and 7.01(7)(with respect to Significant
Subsidiaries) ("covenant defeasance option"). The Corporation may exercise its
defeasance option notwithstanding its prior exercise of its covenant defeasance
option.

          If the Corporation exercises its legal defeasance option, the
Securities may not be accelerated because of an Event of Default. If the
Corporation exercises its covenant defeasance option, the Securities, may not be
accelerated because of an Event of Default specified in Sections 7.01(3), (4),
(5), (6) and (7) (with respect to Significant Subsidiaries) or because of the
failure of the Corporation to comply with Section 6.01(a)(iii).

          Before or after a deposit, the Corporation may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article 4.

                                       46

<PAGE>

          Upon satisfaction of the conditions set forth herein and upon request
of the Corporation, the Trustee shall acknowledge in writing the discharge of
those obligations that the Corporation terminates.

          (c) Notwithstanding clauses (a) and (b) above, the Corporation's
obligations in Sections 2.03, 2.04, 2.05, 2.08, 2.09, 8.07, 8.08, 9.04, 9.05 and
9.06 shall survive until the Securities have been paid in full. Thereafter the
Corporation's obligations in Sections 8.07, 9.04 and 9.05 shall survive.

          SECTION 9.02 Conditions to Defeasance. The Corporation may exercise
                       ------------------------
its legal defeasance option or its covenant defeasance option only if:

          (1) the Corporation irrevocably deposits in trust with the Trustee
     money or U.S. Government Obligations for the payment of principal and
     interest on the Securities to maturity or redemption, as the case may be;

          (2) the Corporation delivers to the Trustee a certificate from a
     nationally recognized firm of independent accountants expressing their
     opinion that the payments of principal and interest when due and without
     reinvestment on the deposited U.S. Government Obligations plus any
     deposited money without investment will provide cash at such times and in
     such amounts (but not more than such amounts) as will be sufficient to pay
     principal and interest when due on all the Securities to maturity or
     redemption, as the case may be;

          (3) 123 days pass after the deposit is made and during the 123 day
     period no Event of Default specified in Section 7.01(7) or (8) (without
     giving effect to the period of time referred to therein) occurs which is
     continuing at the end of the period;

          (4) no Default or Event of Default has occurred and is continuing on
     the date of such deposit and after giving effect thereto and is not
     prohibited by Article 12;

          (5) the Corporation delivers to the Trustee an Opinion of Counsel to
     the effect that the trust resulting from the deposit does not constitute,
     or is qualified as, a regulated investment Corporation under the Investment
     Corporation Act of 1940;

          (6) In the case of the legal defeasance option, the Corporation shall
     have delivered to the Trustee an Opinion of Counsel stating that (i) the
     Corporation has received from, or there has been published by, the Internal
     revenue Service a ruling, or (ii) since the date of this Indenture there
     has been a change in the applicable Federal income tax law, in either case
     to the effect that, and based thereon such Opinion of Counsel shall confirm
     that, the Security holders will not recognize income, gain or loss for
     Federal income tax purposes as a result of such defeasance and will be
     subject to Federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such defeasance had not
     occurred;

          (7) in the case of the covenant defeasance option, the Corporation
     shall have delivered to the Trustee an opinion of Counsel to the effect
     that the Securityholders will not recognize income, gain or loss for
     Federal income tax purposes as a result of such

                                    47

<PAGE>

     covenant defeasance and will be subject to Federal income tax on the same
     amounts, in the same manner and at the same times as would have been the
     case if such covenant defeasance had not occurred; and

          (8) the Corporation delivers to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent to
     the defeasance and discharge of the Securities as contemplated by this
     Article 9 have been complied with.

          SECTION 9.03 Application of Trust Money. The Trustee shall hold in
                       --------------------------
trust money or U.S. Government Obligations deposited with it pursuant to Section
9.02. It shall apply the deposited money and the money from U.S. Government
Obligations through the Paying Agent and in accordance with this Indenture to
the payment of principal of and interest on the Securities. Money and securities
so held in trust are not subject to Article 12.

          SECTION 9.04 Repayment to Corporation. The Trustee and the Paying
                       ------------------------
Agent shall promptly turn over to the Corporation upon request any excess money
or securities held by them at any time.

          Subject to any applicable abandoned property law, the Trustee and the
Paying Agent shall pay to the Corporation upon request any money held by them
for the payment of principal or interest that remains unclaimed for two years
and, thereafter, Securityholders entitled to the money must look to the
Corporation for payment as general creditors.

          SECTION 9.05 Indemnity for Government Obligations. The Corporation
                       ------------------------------------
shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against deposited U.S. Government Obligations or the
principal and interest received on such U.S. Government Obligations.

          SECTION 9.06 Reinstatement. If the Trustee or Paying Agent is unable
                       -------------
to apply any money or U.S. Government Obligations in accordance with Article 9
by reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Corporation's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Article 9 until such time as the Trustee or Paying Agent is
permitted to apply all such money or U.S. Government Obligations in accordance
with this Article 9; provided, however, that if the Corporation has made any
payment of interest on or principal of any Securities because of the
reinstatement of its obligations, the Corporation shall be subrogated to the
rights of the Holders of such Securities to receive such payment from the money
or U.S. Government Obligations held by the Trustee or Paying Agent.

                       Amendments, Supplements and Waivers
                       -----------------------------------

          SECTION 10.01 Without Consent of Holders. The Corporation and the
                        --------------------------
Trustee may amend or supplement this Indenture or the Securities or the Security
Agreement without notice to or consent of any Securityholder:

                                       48

<PAGE>

          (1) to cure any ambiguity, omission, defect or inconsistency;

          (2) to comply with Article 6;

          (3) to provide for uncertificated Securities in addition to or in
     place of certificated Securities;

          (4) to add to the covenants of the Corporation for the benefit of the
     Holders or to surrender any right or power herein conferred upon the
     Corporation;

          (5) to comply with any requirements of the SEC in connection with the
     qualification of the Indenture under the TIA; or

          (6) to make any change that does not materially adversely affect the
     legal rights of any Securityholder under this Indenture.

          Upon the Corporation's request, after receipt by the Trustee of a
resolution of the Board of Directors authorizing the execution of any amended or
supplemental indenture, the documents described in Section 10.06 hereof, the
Trustee shall join with the Corporation in the execution of any amended or
supplemental indenture authorized or permitted by the terms of this Indenture
and to make any further appropriate agreements and stipulations that may be
contained in any such amended or supplemental indenture, but the Trustee shall
not be obligated to enter into an amended or supplemental indenture that affects
its own rights, duties or immunities under this Indenture or otherwise.

          SECTION 10.02 With Consent of Holders. The Corporation may amend or
                        -----------------------
supplement this Indenture or the Securities or the Security Agreement without
notice to any Securityholder but with the written consent of the Holders of at
least a majority in principal amount of the Securities. The Holders of a
majority in principal amount of the Securities may waive any past default or
compliance by the Corporation with any provision of this Indenture or the
Securities or the Security Agreement without notice to any Securityholder.
However, without the consent of each Securityholder affected, an amendment,
supplement or waiver, including a waiver pursuant to Section 7.04, may not:

          (1) reduce the amount of Securities whose Holders must consent to an
     amendment, supplement or waiver;

          (2) reduce the rate of or extend the time for payment of interest on
     any Security;

          (3) reduce the principal of or extend the fixed maturity of any
     Security;

          (4) reduce the premium payable upon the redemption of any Security or
     change the time whereby any Security may be redeemed in accordance with
     Article 4;

          (5) make any Security payable in money other than that stated in the
     Security;

          (6) make any change in Section 7.04 or 7.07 or this Section; or

                                       49

<PAGE>

          (7) waive any Default in the payment of principal of or interest on
     any Security.

          Upon the Corporation's request and after receipt by the Trustee of a
resolution of the Board of Directors authorizing the execution of any
supplemental indenture, evidence of the Holders' consent, and the documents
described in Section 10.06 hereof, the Trustee shall join with the Corporation
in the execution of any amended or supplemental indenture unless such amended or
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise, in which case the Trustee may in its
discretion, but not be obligated to, enter into such amended or supplemental
indenture.

          It shall not be necessary for the consent of the Holders under this
Section 10.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

          After an amendment under this Section becomes effective, the
Corporation shall mail to Securityholders a notice briefly describing such
amendment. The failure to give such notice to all Securityholders, or any defect
therein, shall not impair or affect the validity of an amendment otherwise
validly adopted under this Section 10.02.

          SECTION 10.03 Compliance with Trust Indenture Act. Every amendment to
                        -----------------------------------
or supplement of this Indenture or the Securities shall comply with the TIA as
then in effect.

          SECTION 10.04 Revocation and Effect of Consents. A consent to an
                        ---------------------------------
amendment, supplement or waiver by a Holder of a Security shall bind the Holder
and every subsequent Holder of that Security or portion of the Security that
evidences the same debt as the consenting Holder's Security, even if notation of
the consent is not made on the Security. However, any such Holder or subsequent
Holder may revoke the consent as to such Holder's Security or portion of the
Security if the Trustee receives the notice of revocation before the date the
amendment, supplement or waiver becomes effective. After an amendment,
supplement or waiver becomes effective in accordance with Section 10.01 or
10.02, it shall bind every Securityholder.

          The Corporation may, but shall not be obligated to, fix a record date
for the purpose of determining the Securityholders entitled to give their
consent or take any other action described above or required or permitted to be
taken pursuant to this Indenture. If a record date is fixed, then
notwithstanding the immediately preceding paragraph, those Persons who were
Securityholders at such record date (or their duly designated proxies), and only
those Persons, shall be entitled to give such consent or to revoke any consent
previously given or to take any such action, whether or not such Persons
continue to be Holders after such record date. No such consent shall be valid or
effective for more than 120 days after such record date.

          SECTION 10.05 Notation on or Exchange of Securities. If an amendment,
                        -------------------------------------
supplement or waiver changes the terms of a Security, the Trustee may require
the Holder of the Security to deliver it to the Trustee. The Trustee may place
an appropriate notation on the Security regarding the changed terms and return
it to the Holder. Alternatively, if the

                                       50

<PAGE>

Corporation or the Trustee so determines, the Corporation in exchange for the
Security shall issue and the Trustee shall authenticate a new Security that
reflects the changed terms.

          SECTION 10.06 Trustee To Sign Amendments. The Trustee shall sign any
                        --------------------------
amendment, supplement or waiver authorized pursuant to this Article if the
amendment, supplement or waiver does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may but need
not sign it. In signing such amendment, supplement or waiver the Trustee shall
be entitled to receive an indemnity satisfactory to it and to receive, and
(subject to Section 8.01) shall be fully protected in relying upon, an Officers'
Certificate and an Opinion of Counsel stating that such amendment, supplement or
waiver is authorized or permitted by this Indenture.

          SECTION 10.07 Payment for Consent. Neither the Corporation nor any
                        -------------------
Affiliate of the Corporation shall, directly or indirectly, pay or cause to be
paid any consideration, whether by way of interest, fee or otherwise, to any
Holder for or as an inducement to any consent, waiver or amendment of any of the
terms or provisions of this Indenture or the Securities unless such
consideration is offered to be paid to all Holders that so consent, waive or
agree to amend in the time frame set forth in solicitation documents relating to
such consent, waiver or agreement.

                            Concerning the Collateral
                            -------------------------

          SECTION 11.01 Security Agreement. To secure the due and punctual
                        ------------------
payment of the principal of and interest on the Securities when and as the same
shall be due and payable, whether on a payment date, at maturity, by
acceleration or otherwise, and interest on the overdue principal of and interest
(to the extent permitted by law), if any, on the Securities and performance of
all other obligations of the Corporation to the Holders or the Trustee under
this Indenture and the Securities, according to the terms hereunder or
thereunder, the Corporation has simultaneously with the execution of this
Indenture granted a security interest to the Trustee, as Collateral Agent, of
its right, title and interest in and to the Collateral pursuant to the Security
Agreement in the manner and to the extent therein provided. The Trustee is
hereby authorized ands directed to execute and deliver such Security Agreement
in the form presented to it. Each Holder, by accepting a Security, authorizes
the Trustee to enter into and perform the Security Agreement, and agrees to all
of the terms and provisions of the Security Agreement, as the same may be in
effect or may be amended from time to time pursuant to its terms and the terms
hereof. The Corporation will execute, acknowledge and deliver to the Trustee, as
the Collateral Agent, such further assignments, transfers, assurances or other
instruments as the Trustee may require or request, and will do or cause to be
done all such acts and things as may be necessary or proper, or as may be
reasonably required by the Trustee, as the Collateral Agent, including the
furnishing of an Opinion of Counsel, to assure and confirm to the Trustee, as
the Collateral Agent the security interest in the Collateral contemplated
hereby, by the Security Agreement, or by any part thereof, as from time to time
constituted, so as to render the same available for the security and benefit of
this Indenture and of the Securities secured hereby, according to the intent and
purposes herein expressed.

          SECTION 11.02 Payment of Expenses. On demand of the Trustee, the
                        -------------------
Corporation forthwith shall pay or satisfactorily provide for payment of
reasonable compensation, reimbursement of expenses and indemnification of the
Trustee as Collateral Agent, and all such sums shall be a lien upon the
Collateral and shall be secured thereby.

          SECTION 11.03 Opinions as to Recording, etc. If this Indenture is
                        -----------------------------
being qualified under the TIA:

          (a) the Corporation shall furnish to the Trustee, promptly after the
     execution of this Indenture on the Security Agreement, an Opinion of
     Counsel either stating that in the opinion of such Counsel the actions
     necessary to be taken with respect to the recording, registering and filing

                                  Subordination
                                  -------------

          SECTION 12.01 Agreement to Subordinate. The Corporation agrees, and
                        ------------------------
each Securityholder by accepting a Security agrees, that the indebtedness
evidenced by the Securities is subordinated in right of payment, to the prior
payment in full of the Senior Discount Notes, and that the subordination is for
the benefit of the holders of the Senior Discount Notes.

          SECTION 12.02 Liquidation; Dissolution; Bankruptcy. Upon any
                        ------------------------------------
distribution to creditors of the Corporation in a liquidation, dissolution or
winding up of the Corporation or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Corporation or its property:

          (1) holders of the Senior Discount Notes shall be entitled to receive
     cash payment in full of the principal of, interest on and all other
     obligations due in respect of the Senior Discount Notes (including, to the
     extent permitted by applicable law, interest on or after the commencement
     of a bankruptcy, reorganization, insolvency, receivership or similar
     proceeding relating to the Corporation or its property, whether or not
     representing an allowed claim in such proceeding) before the
     Securityholders shall be entitled to receive any payments of principal of
     or premium, if any, or interest on or other obligations due in respect of
     the Securities; and

          (2) until the principal of, interest on and all other obligations due
     in respect of the Senior Discount Notes have been paid in full in cash, any
     distribution of cash, securities or other property to which Securityholders
     would be entitled but for this Article shall be made to the holders of the
     Senior Discount Notes as their interests may appear.

          SECTION 12.03 Corporation Not to Make Payments With Respect to
          --------------------------------------------------------------
Securities While Senior Discount Notes are Outstanding. The principal of,
------------------------------------------------------
interest on and all other obligations due in respect of the Senior Discount
Notes shall first be paid in full in cash, before any payment (including any
payment as a result of any acceleration of the Securities) is made on account of
the principal of or premium, if any, or interest on, or other obligations due in
respect of the Securities or on account of the purchase, redemption, defeasance
or other acquisition in respect of any of the Securities.

          SECTION 12.04 Subordination of Security Interest. The security
                        ----------------------------------
interest in the Collateral granted to the Trustee for the benefit of the
Securityholders as security for the payment of the Securities shall be, in all
respects, subject, junior and subordinate to the security interest in the
Collateral granted to holders of the Senior Discount Notes or to any agent
acting on behalf of the holders of the Senior Discount Notes, notwithstanding
anything to the contrary contained in any agreement or filing to which the
Trustee or any Securityholder may now or hereafter be a party, and irrespective
of the time, order or method of attachment or perfection of any financing
statements or other security interests or any defect or deficiency or alleged
defect or deficiency in any of the foregoing. The proceeds of any sale,
disposition or other realization upon all or any part of the Collateral, after
satisfaction of the expenses of the collection of such Collateral and the
enforcement of the rights of the holders of the Senior Discount Notes in such

                                       53

<PAGE>

Collateral, shall be applied to the payment in fall in cash of the principal of,
interest on and all other obligations due in respect of the Senior Discount
Notes before the Securityholders shall be entitled to receive any portion of
such proceeds in respect of the Securities. The security interest priorities
provided in this Article shall not be altered or otherwise affected by any
amendment, modification, supplement, extension, renewal, restatement or
refinancing of either the Senior Discount Notes or the Securities, nor by any
action or inaction which the holders of the Senior Discount Notes, any agent
acting on behalf of the holders of the Senior Discount Notes, the Trustee or any
Securityholder may take or fail to take in respect of the Collateral. The
Trustee (for itself and on behalf of the Securityholders) agrees that it will
not contest the validity, perfection, priority or enforceability of the security
interests in the Collateral of the holders of the Senior Discount Notes or of
any agent acting on behalf of the holders of the Senior Discount Notes, or the
respective priorities of the security interests securing the Senior Discount
Notes and the Securities set forth in this Article, or the validity or
reasonableness of any act or omission by the holders of the Senior Discount
Notes or by any agent acting on behalf of the Senior Discount Notes, including,
without limitation, the timing, method, or manner of collecting or otherwise
realizing upon the Collateral. As between the holders of the Senior Discount
Notes and the Securityholders, the terms of this Article shall govern even if
part or all of the Senior Discount Notes or the security interests securing
payment and performance thereof are not perfected or are avoided, disallowed,
set aside or otherwise invalidated in any judicial proceeding or otherwise.

          SECTION 12.05 Acceleration of Securities. If payment of the Securities
                        --------------------------
is accelerated because of an Event of Default, the Corporation shall promptly
notify holders of the Senior Discount Notes of the acceleration.

          SECTION 12.06 When Distribution Must Be Paid Over. If a distribution
                        -----------------------------------
is made to Securityholders that, because of this Article, should not have been
made to them, the Securityholders who receive the distribution shall hold the
same in trust for the holders of the Senior Discount Notes and shall pay it over
to the holders of the Senior Discount Notes as their interests may appear.

          SECTION 12.07 Notice by Corporation. The Corporation shall promptly
                        ---------------------
notify the Trustee and the Paying Agent of any facts known to the Corporation
that would cause a payment of principal of or premium, if any, or interest on
the Securities to violate this Article.

          SECTION 12.08 Subrogation. After the principal of, interest on and all
                        -----------
other obligations due in respect of the Senior Discount Notes has been paid in
full and until the Securities are paid in full, Securityholders shall be
subrogated to the rights of holders of the Senior Discount Notes to receive
distributions applicable to the Senior Discount Notes to the extent that
distributions otherwise payable to the Securityholders have been applied to the
payment of the Senior Discount Notes. A distribution made under this Article to
holders of the Senior Discount Notes which otherwise would have been made to
Securityholders is not, as between the Corporation and Securityholders, a
payment by the Corporation on the Senior Discount Notes.

          SECTION 12.09 Relative Rights. This Article defines the relative
                        ---------------
rights of Securityholders and holders of the Senior Discount Notes. Nothing in
this Indenture shall:

                                       54

<PAGE>

          (1) impair, as between the Corporation and Securityholders, the
     obligation of the Corporation, which is absolute and unconditional, to pay
     principal of and premium, if any, and interest on the Securities in
     accordance with their terms;

          (2) affect the relative rights of Securityholders and creditors of the
     Corporation, other than holders of the Senior Discount Notes; or

          (3) prevent the Trustee or any Securityholder from exercising its
     available remedies upon a Default, subject to the rights of holders of the
     Senior Discount Notes to receive distributions otherwise payable to
     Securityholders.

If the Corporation fails because of this Article to pay principal of or premium,
if any, or interest on a Security on the due date, such failure shall
nevertheless be deemed a Default.

          SECTION 12.10 Subordination May Not Be Impaired by Corporation. No
                        ------------------------------------------------
right of any holder of the Senior Discount Notes, or any agent acting on behalf
of the Senior Discount Notes, to enforce the subordination of the indebtedness
evidenced by the Securities or the subordination of the security interest
securing the Securities, shall be impaired by any act or failure to act by the
Corporation or by its failure to comply with the terms of this Indenture.

          SECTION 12.11 Effectuation of Subordination by Trustee. Each
                        ----------------------------------------
Securityholder, by acceptance of a Security, authorizes and directs the Trustee
on behalf of such Securityholder to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee attorney-in-fact for such Securityholder for any and all
such purposes.

                        12% Senior Secured Note Due 2008

          Capitalized terms used herein without definition shall have the
meanings ascribed to them in the Indenture dated as of February 22, 2002 between
Ampex Corporation, a Delaware corporation (the "Corporation"), and State Street
Bank and Trust Company, a Massachusetts trust company, as trustee ("Trustee"),
as amended from time to time in accordance with its terms (the "Indenture"), to
which Indenture reference is hereby made for a statement of respective rights,
limitations of rights, duties, obligations and immunities thereunder of the
Corporation, the Trustee and the Holders of the Securities, and of the terms
upon which the Securities are, and are to be, authenticated and delivered.

1.   Interest
     --------

          The Corporation promises to pay interest on the principal amount of
this Security at the rate per annum shown above solely out of Available Cash
Flow for the six-month period ending December 31 or June 30 of each year next
preceding the applicable payment date. If with respect to any payment date, the
Available Cash Flow would be insufficient to make such payment in cash, the
Corporation shall issue additional Securities in an aggregate amount equal to
the amount of the interest otherwise payable on such payment date in accordance
with Section 2.14 of the Indenture; provided, however, that, payment of accrued
and unpaid interest on the Securities at the stated maturity or upon
acceleration shall be due and payable in cash only. Additional Securities shall
be governed by, and entitled to the benefits of, the Indenture. The Corporation
will pay interest to Holders of record at the close of business on the February
1st and August 1st immediately preceding the payment date on February 15 and
August 15 of each year, commencing August 15, 2002. Interest on the Securities
will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the Issue Date. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

2.   Mandatory Prepayment
     --------------------

          In addition to interest payments as set forth in paragraph 1 above,
the Securities are subject to mandatory prepayment payable out of Available Cash
Flow under the circumstances set forth in Section 3.03 of the Indenture.

3.   Method of Payment
     -----------------

          The Corporation will pay interest on the Securities (except defaulted
interest) or make mandatory prepayment, as the case may be, to the persons who
are registered holders of Securities at the close of business on the February 1
or August 1 next preceding the payment date even if Securities are canceled
after the record date and on or before the payment date. Holders must surrender
Securities to a Paying Agent to collect amounts due upon final maturity of the
Securities. The Corporation will pay principal and interest in (other than
interest payable in additional Securities as provided above) money of the United
States that at the time of payment

                                        2

<PAGE>

is legal tender for payment of public and private debts. However, the
Corporation may pay principal and interest by check payable in such money. It
may mail an interest check to a Holder's registered address. At its option, the
Corporation may pay principal and interest by wire transfer to an account
designated in writing by the Holder.

4.   Paying Agent and Registrar
     --------------------------

          Initially, Trustee will act as Paying Agent and Registrar. The
Corporation may appoint and change any Paying Agent, Registrar or co-registrar
without prior notice to any holder, but will promptly notify the Trustee of any
change. The Corporation or any of its Subsidiaries may act as Paying Agent,
Registrar or co-registrar.

5.   Indenture
     ---------

          The Corporation issued the Securities under the Indenture. The terms
of the Securities include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code
Section 77aaa-77bbbb) as in effect on the date of the Indenture (the "Act"). The
Securities are subject to all such terms, and Securityholders are referred to
the Indenture and the Act for a statement of those terms.

          The Securities are general obligations of the Corporation limited to
$50,000,000 aggregate principal amount (subject to Section 2.11 of the
Indenture) plus additional Securities issuable in payment of interest as
provided hereunder. The Indenture imposes certain limitations on the payment of
dividends and other distributions by the Corporation and certain of its
Subsidiaries, the sale or transfer of assets, the sale or transfer of shares of
stock of certain of its Subsidiaries, the incurrence of debt by the Corporation
and certain of its Subsidiaries and transactions with affiliates.

6.   Subordination
     -------------

          The Securities are subordinated to the prior payment in full of
certain Senior Discount Notes as provided in Article 12 of the Indenture.

7.   Optional Redemption
     -------------------

          Subject to the prior payment of the Senior Discount Notes, the
Corporation may redeem the Securities at any time as a whole, or from time to
time in part, at a redemption price equal to 100% of the principal amount to be
redeemed plus accrued interest to the redemption date.

8.   Notice of Redemption
     --------------------

          Notice of redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each Holder of Securities to be redeemed
at the Holder's registered address. If money sufficient to pay the redemption
price and accrued interest on all Securities to be redeemed on the redemption
date is deposited with the Paying Agent prior to the redemption date, on and
after such date interest ceases to accrue on such Securities or portions of
them.

                                        3

<PAGE>

Securities in denominations larger than $1,000 may be redeemed in part but only
in whole multiples of $1,000.

9.   Security
     --------

          The Securities are secured by a lien on the Collateral (subject to the
rights of the holders of the Senior Discount Notes granted pursuant to a Senior
Security Agreement) pursuant to a Security Agreement described in the Indenture.

10.  Denominations; Transfer; Exchange
     ---------------------------------

          The Securities are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the Indenture. The Registrar may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
and to pay any taxes and fees required by law or permitted by the Indenture. The
Registrar need not transfer or exchange any Securities selected for redemption
(except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or any Securities for a period of 15 days before a
selection of Securities to be redeemed or before an payment date.

11.  Persons Deemed Owners
     ---------------------

          The registered holder of this Security may be treated as the owner of
it for all purposes.

12.  Unclaimed Money
     ---------------

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Corporation at its request unless an abandoned property law designates another
person. After any such payment, Holders entitled to the money must look only to
the Corporation (unless abandoned property law designates another person) and
not to the Trustee for payment.

13.  Satisfaction and Discharge of Indenture
     ---------------------------------------

          On the terms and subject to certain conditions specified in the
Indenture, the Corporation will be discharged from the Indenture and the
Securities (other than certain specified provisions) or will be discharged from
certain covenants under the Indenture and the Securities upon deposit with the
Trustee of moneys or U.S. Government Obligations sufficient to pay at maturity
or upon redemption all Securities not previously delivered to the Trustee for
cancellation, including principal and accrued interest and all other sums then
payable by the Corporation under the Indenture.

14.  Amendment, Supplement, Waiver
     -----------------------------

          Subject to certain exceptions, (i) the Indenture or the Securities may
be amended or supplemented with the written consent of the Holders of at least a
majority in principal amount outstanding of the Securities, and (ii) any past
default or noncompliance with any

                                        4

<PAGE>

provision may be waived with the written consent of the Holders of a majority in
principal amount outstanding of the Securities. Subject to certain exceptions,
without the consent of any Securityholder, the Corporation and the Trustee may
amend or supplement the Indenture or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 6 of the Indenture,
or to provide for uncertificated Securities in addition to or in place of
certificated Securities or to make any change that does not adversely affect the
rights of any Securityholder.

15.  Defaults and Remedies
     ---------------------

          Each of the following is an Event of Default: default for 30 days in
payment of any interest on the Securities; default in payment of any principal
of the Securities when the same becomes due and payable at stated maturity, upon
redemption, upon declaration or otherwise; failure by the Corporation for 30
days after notice to the Corporation by the Trustee or to the Corporation and
the Trustee by the Holders of at least 25% aggregate principal amount of the
Securities to comply with certain covenants and agreements in the Indenture
relating to the payment of dividends and other distributions by the Corporation
and Subsidiaries, the sale or transfer of assets, the incurrence of debt by the
Corporation and Subsidiaries, transactions with affiliates and certain mergers,
consolidations and transfers of assets; failure by the Corporation for 60 days
after notice to the Corporation by the Trustee or to the Corporation and the
Trustee by the Holders of at least 25% aggregate in principal amount of the
Securities to comply with certain other covenants and agreements in the
Indenture and the Securities; failure of the Corporation to receive the Minimum
Available Cash Flow; certain payment defaults with respect to other indebtedness
of the Corporation or certain of its Subsidiaries, or other defaults resulting
in the acceleration of such other indebtedness, where the aggregate of such
indebtedness exceeds $5,000,000; and certain events of bankruptcy or insolvency.
If an Event of Default occurs and is continuing, the Holders of at least 25% in
principal amount of the Securities may declare the principal of and accrued
interest on all the Securities to be due and payable immediately.
Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in principal amount of the Securities
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Securityholders notice of any continuing Default or Event of
Default (except a Default in payment of principal or interest) if it determines
that withholding notice is in their interest.

16.  Trustee Dealings with the Corporation
     -------------------------------------

          Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Corporation or its affiliates and may otherwise deal with the
Corporation or its affiliates with the same rights it would have if it were not
Trustee.

                                        5

<PAGE>

17.  No Recourse Against Others
     --------------------------

          A director, officer, employee or stockholder, as such, of the
Corporation and the Trustee shall not have any liability for any obligations of
the Corporation under the Securities or the Indenture or for any claim based on,
in respect of or by reason of such obligations or their creation. By accepting a
Security, each Securityholder waives and releases all such liability. The waiver
and release are part of the consideration for the issue of the Securities.

18.  Authentication
     --------------

          This Security shall not be valid until authenticated by the manual
signature of the Trustee or an authenticating agent on the other side of this
Security.

19.  Abbreviations
     -------------

          Customary abbreviations may be used in the name of a Securityholder or
an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with right of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

20.  CUSIP Numbers
     -------------

          Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Corporation has caused CUSIP numbers to
be printed on the Securities and has directed the Trustee to use CUSIP numbers
in notices of redemption as a convenience to Security holders. No representation
is made as to the accuracy of such numbers either as printed on the Securities
or as contained in any notice of redemption and reliance may be placed only on
the other identification numbers placed thereon.

          The Corporation will furnish to any Securityholder upon written
request and without charge to such Holder a copy of the Indenture which has in
it the text of this Security in larger type. Requests may be made to: Ampex
Corporation, 135 East 57th Street, New York, New York 10022, Attention of Vice
President.
