                                   ARTICLE 1



                  Definitions and Incorporation by Reference
                  ------------------------------------------


           SECTION 1.01.  Definitions.
                          ------------

          "Additional Assets" means (a) any Property (other than cash, cash
equivalents and securities) to be owned by the Company or any Restricted
Subsidiary and used in a Related Business; or (b) Capital Stock of a Person that
becomes a Restricted Subsidiary as a result of the acquisition of such Capital
Stock by the Company or another Restricted Subsidiary from any Person other than
an Affiliate of the Company; provided, however, that, in the case of clause (b),
                             --------  -------                                  
such Restricted Subsidiary is primarily engaged in a Related Business.

          "Affiliate" of any specified Person means (a) any other Person

common control with such specified Person or (b) any other Person who is a
director or officer of (i) such specified Person, (ii) any Subsidiary of such
specified Person or (iii) any Person described in clause (a) above. For the
purposes of this definition, "control" when used with respect to any Person
means the power to direct the management and policies of such Person, directly

or otherwise; and the terms "controlling" and "controlled" have meanings
correlative to the foregoing. For purposes of Section 4.06, Section 4.07 and the
definition of "Additional Assets" only, "Affiliate" shall also mean any
beneficial owner of shares representing 5% or more of the total voting power of
the 

 
                                                                               2

Voting Stock (on a fully diluted basis) of the Company or of rights or
warrants to purchase such Voting Stock (whether or not currently exercisable)

Initial Securities and the Exchange Securities are set forth in Appendix A,
which is hereby incorporated in and expressly made a part of this Indenture. The
Initial Securities of each series and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit 1 to Appendix A
which is hereby incorporated in and expressly made a part of this Indenture.
The Exchange Securities and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A, which is hereby incorporated in and
expressly made a part of this Indenture.  The Securities may have notations,
legends or endorsements required by law, stock exchange rule, agreements to
which the Company is subject, if any, or usage, provided that any such notation,
                                                --------                        
legend or endorsement is in a form reasonably acceptable to the Company.  Each
Security shall be dated the date of its authentication.  The terms of the
Securities set forth in Exhibit 1 to Appendix A and Exhibit A are part of the
terms of this Indenture.

          (b)  Upon their original issuance, Rule 144A Securities shall be
issued in the form of one or more Global Notes registered in the name of the
Depository or its nominee and deposited with the Trustee, as custodian for the
Depository, duly executed by the Company and authenticated by the Trustee, for
credit by the Depository to the respective accounts of beneficial owners of the
Securities represented thereby (or such other accounts as they may direct).
Such Global Notes are collectively herein called the "Rule 144A Global Note".
Upon their original issuance, Regulation S Securities shall, to the extent
required pursuant to paragraph (C)(3)(ii)(B) of Rule 903 under Regulation S
under the Securities Act, be issued in the form of one or more temporary Global
Notes (the "Temporary Regulation S Global Notes") and, to the extent permitted
pursuant to paragraph (C)(3)(ii)(B) of such Rule 903, shall be issued initially
in the form of one or more permanent Global Notes (the "Permanent Regulation S
Global Notes"), in each case registered in the name of the Depository or its
nominee and deposited with the Trustee as custodian for the Depository, duly
executed by the Company and authenticated by the Trustee, for credit to the
Agent Member accounts at the Depository of Euroclear and/or Cedel for further
credit by Euroclear and Cedel, as the case may be, to the 

 
                                                                              33

respective accounts of the beneficial owners of the Securities represented
thereby (or such other accounts as they may direct). Interests in the Temporary
Regulation S Global Notes may only be held by the Agent Members of the
Depository for Euroclear and Cedel.

          SECTION 2.03.  Execution and Authentication.  Two Officers shall sign
                         -----------------------------                         
the Securities for the Company by manual or facsimile signature.  The Company's
seal shall be impressed, affixed, imprinted or reproduced on the Securities
and may be in facsimile form.

          If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall
be valid nevertheless.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a written order of the
Company signed by two Officers or by an Officer and either an Assistant
Treasurer or an Assistant Secretary of the Company for the authentication and
delivery of such Securities, and the Trustee in accordance with such written
order of the Company shall authenticate and deliver such Securities.

          A Security shall not be valid until an authorized officer or signatory
of the Trustee manually signs the certificate of authentication on the Security.
The signature shall be conclusive evidence that the Security has been
authenticated under this Indenture.

          The Trustee may appoint an authenticating agent reasonably acceptable
to the Company to authenticate the Securities. Unless limited by the terms of
such appointment, an authenticating agent may authenticate Securities whenever
the Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as any Registrar, Paying Agent or agent for service of notices and
demands.

          SECTION 2.04.  Registrar and Paying Agent.  The Company shall maintain
                         ---------------------------                            
in the Borough of Manhattan, the City of New York, an office or agency where
Securities may be presented for registration of transfer or for exchange (the
"Registrar") and an office or agency where Securities may be presented for
payment (the "Paying Agent"). The Registrar 

 
                                                                              34

shall keep a register of the Securities and of their transfer and exchange. The
Company may have one or more co-registrars and one or more additional paying
agents. The term "Paying Agent" includes any additional paying agent.

          The Company may also from time to time designate one or more other
offices or agencies (in or outside the Borough of Manhattan, the City of Mew
York) where the Securities may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations; provided, however,
                                                              --------  ------- 
that no such designation or recision shall in any manner relieve the Company of
its obligation to maintain an office or agency in the Borough of Manhattan, the
City of New York, for such purposes. The Company will give written notice to the
Trustee of any such designation or recision and of any change in the location of
any such other office or agency.

          The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the name and address of any such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any of its domestically incorporated Wholly Owned Subsidiaries may
act as Paying Agent, Registrar, co-registrar or transfer agent. The Company may
change any Paying Agent or Registrar upon notice to the Trustee but without
notice to any Holder.

          The Company initially appoints the Trustee as Registrar and Paying
Agent in connection with the Securities.

          SECTION 2.05.  Paying Agent To Hold Money in Trust.  No later than
                         ------------------------------------               
11:00 a.m., New York City time, on or prior to each due date of the principal
and interest on any Security, the Company shall deposit with the Paying Agent,
on such due date, a sum sufficient to pay such principal and interest then so
becoming due. The Company shall require each Paying Agent (other than the
Trustee) to agree in writing that the Paying Agent shall hold in trust for the
benefit of Securityholders or the Trustee all money held by the Paying Agent for
the payment of principal of or interest on the Securities and shall notify the
Trustee of any default by the Company in making any such payment. If the Company
or a Wholly Owned Subsidiary acts as Paying Agent, 

 
                                                                              35

it shall segregate the money held by it as Paying Agent and hold it as a
separate trust fund. The Company at any time may require a Paying Agent to pay
all money held by it to the Trustee and to account for any funds disbursed by
the Paying Agent. Upon complying with this Section, the Paying Agent shall have
no further liability for the money delivered to the Trustee.

          SECTION 2.06.  Securityholder Lists.  The Trustee shall preserve in as
                         ---------------------                                  
current a form as is reasonably practicable the most recent list available to
it of the names and addresses of Securityholders. If the Trustee is not the
Registrar, the Company shall furnish to the Trustee, in writing at least five
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Securityholders.

          SECTION 2.07.  Replacement Securities.  If a mutilated Security is
                         -----------------------                            
surrendered to the Registrar or if the Holder of a Security claims that such
Security has been lost, destroyed or wrongfully taken, the Company 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 and the Company. If required by
the Trustee or the Company, such Holder shall furnish an indemnity bond
sufficient in the judgment of the Company and the Trustee to protect the
Company, 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 Company and
the Trustee may charge the Holder for their expenses in replacing a Security.

          Every replacement Security is an additional obligation of the Company.

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
of mutilated, lost, destroyed or wrongfully taken Securities.

          SECTION 2.08.  Outstanding Securities.  Securities outstanding at any
                         -----------------------                               
time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancelation and those described in this Section
as not outstanding. A Security does not cease to be outstanding because the
Company or an Affiliate of the Company holds the Security.

 
                                                                              36

          If a Security is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a bona fide purchaser.

          If the Paying Agent segregates and holds in trust, in accordance with
this Indenture, on a redemption date or maturity date money sufficient to pay
all principal and interest payable on that date with respect to the Securities
(or portions thereof) to be redeemed or maturing, as the case may be, and the
Paying Agent is not prohibited from paying such money to the Securityholders on
that date 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.

          SECTION 2.09.  Temporary Securities.  Until definitive Securities are
                         ---------------------                                 
ready for delivery, the Company 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 Company considers
appropriate for temporary Securities. Every such temporary Security shall be
authenticated upon the same conditions and in substantially the same manner,
and with the same effect, as the definitive Securities. Without unreasonable
delay, the Company shall prepare and the Trustee shall authenticate definitive
Securities and deliver them in exchange for temporary Securities. Such exchange
shall be made by the Company at its own expense and without any charge therefor.
Until so exchanged, the temporary Securities shall in all respects be entitled
to the same rights, privileges and benefits under this Indenture as definitive
Securities authenticated and delivered hereunder.

          SECTION 2.10.  Cancelation.  The Company at any time may deliver
                         ------------                                     
Securities to the Trustee for cancelation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of 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 registration of transfer, exchange, payment or
cancelation and deliver a certificate of such destruction to the Company, unless
the Company directs the Trustee to deliver canceled Securities to the Company.
If the Company shall acquire any of the Securities, such acquisition shall not
operate as a redemption or satisfaction of the Debt represented by such
Securities unless and until the same are delivered to the Trustee for
cancelation. The Company may 

 
                                                                              37

not issue new Securities to replace Securities it has redeemed, paid or
delivered to the Trustee for cancelation.

          SECTION 2.11.  Defaulted Interest.  If the Company defaults on a
                         -------------------                              
payment of interest on the Securities, the Company shall pay defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner. The Company may pay the defaulted interest to the persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail to each
Securityholder a notice that states the special record date, the payment date
and the amount of defaulted interest to be paid. Notwithstanding the foregoing,
any interest which is paid prior to the expiration of the grace period provided
for in Section 6.01(1) hereof shall be paid to the Holders of the Securities as
of the regular record date for which interest has not been paid.

          SECTION 2.12.  CUSIP Numbers.  The Company 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 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 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

                                  ----------



          SECTION 3.01.  Notices to Trustee.  If the Company redeems Securities
                         -------------------                                   
pursuant to paragraph 5 of the Securities, it shall notify the Trustee in
writing of the redemption date, the principal amount of Securities to be
redeemed and whether such redemption is being made pursuant to paragraph 5(a) or
5(b) of the Securities.

          In the event of a redemption pursuant to paragraph 5(a) of the
Securities, the Company shall give each notice to the Trustee provided for in
this Section at least 45 days before the redemption date unless the Trustee
consents to a shorter period.  In the event of a redemption 

 
                                                                              38

pursuant to paragraph 5(b) of the Securities, the Company shall give the notice
to the Trustee provided for in this Section no later than 5:00 p.m., New York
City time, on April 10, 1998. Any notice pursuant to this Section shall be
transmitted by facsimile and confirmed with a Trust Officer by telephone. Such
notice shall be accompanied by an Officers' Certificate and an Opinion of
Counsel from the Company to the effect that such redemption will comply with the
conditions herein. Such Officers' Certificate shall, in addition, specify the
redemption price of the Securities.

          SECTION 3.02.  Selection of Securities To Be Redeemed.  If less than
                         ---------------------------------------              
all the Securities are to be redeemed at any time, selection of Securities for
redemption may be made by the Trustee in compliance with the requirements of
the principal national securities exchange, if any, on which the Securities are
listed, or, if the Securities are not so listed, on a pro rata basis, by lot or
by such other method that the Trustee shall deem fair and appropriate (and in a
manner that complies with applicable legal 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. Securities and portions
of them the Trustee selects shall be in amounts of $1,000 or a whole multiple of
$1,000. 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 Company and, unless the Trustee is acting as such, the
Registrar, promptly of the Securities or portions of Securities to be redeemed.

          SECTION 3.03.  Notice of Redemption.  The Company shall mail a notice
                         ---------------------                                 
of redemption by first-class mail to each Holder of Securities to be redeemed
(i) in the case of a redemption under paragraph 5(a) of the Securities at least
30 days but not more than 60 days before a date for redemption of Securities,
and (ii) in the case of a redemption under paragraph 5(b) of the Securities on
April 10, 1998.

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

          (1)  the redemption date;

          (2)  the redemption price, or the calculation thereof described in
     paragraph 5 of the Securities;

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

 
                                                                              39

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

          (5)  if fewer 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 Company defaults in making such redemption
     payment or the Paying Agent is prohibited from making such payment pursuant
     to the terms of this Indenture, interest on Securities (or portion thereof)
     called for redemption ceases to accrue on and after the redemption date;
     and

          (7)  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 Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with the information required by this
Section.

          In the event of a redemption pursuant to paragraph 5(b) of the
Securities, the Company will, on April 10, 1998, cause a notice of such
redemption to be sent at least once to the Dow Jones News Service or similar
business news service in the United States.

          SECTION 3.04.  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, and from
and after such redemption date (unless the Company shall default on the payment
of the redemption price and accrued interest) such Securities shall cease to
bear interest. 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 (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date that
is on or prior to the date of redemption). 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 3.05.  Deposit of Redemption Price.  No later than 11:00 a.m.,
                         ----------------------------

Agent, shall segregate and hold in trust) money sufficient to pay the redemption
price of and accrued interest (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date that is on or prior to the date of redemption) 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 Company to the Trustee for
cancelation. All money earned on funds held in trust by the Trustee or any
Paying Agent and any excess or remaining funds shall be remitted to the Company.
In the event of a redemption pursuant to paragraph 5(b) of the Securities,
Holding will, on April 10, 1998, deposit with (and not withdraw) the Trustee (or
a paying agent designated by the Trustee) money sufficient to pay the redemption
price. The Trustee (or the paying agent) will invest such funds in cash or
Temporary Cash Investments as directed in writing by the Company pending
distribution to Holders on April 24, 1998. The Trustee (or the paying agent)
shall not be accountable or liable for any losses from the sale or depreciation
in value of such investments.

          Subject to any applicable abandoned property law, the Trustee and the
Paying Agent shall pay to the Company upon request any money held by them for
the payment of the redemption price of and accrued interest, if any, on the
Securities that remains unclaimed for two years (or if then held by the Company
or a Wholly Owned Subsidiary in trust for the payment thereof), shall be
discharged from such trust, and, thereafter, Securityholders entitled to the
money must look to the Company for payment as general creditors; provided,
                                                                 --------

such repayment shall at the expense of the Company cause to be mailed to each
such Holder a notice that said moneys have not been so applied and that after a
date named therein any unclaimed balance of said moneys then remaining will be
returned to the Company.

          SECTION 3.06.  Securities Redeemed in Part.  Upon surrender of a
                         ----------------------------                     
Security that is redeemed in part, the Company shall execute and the Trustee
shall authenticate for the Holder (at the Company's expense) a new Security
equal in principal amount to the unredeemed portion of the Security surrendered.

 
                                                                              41

          SECTION 4.01.  Payment of Securities.  The Company shall promptly pay
                         ----------------------                                
the principal of and interest on the Securities on the dates and in the manner
provided in the Securities and in this Indenture. Principal and interest shall
be considered paid on the date due if on such date the Trustee or the Paying
Agent holds in accordance with this Indenture money sufficient to pay all
principal and interest then due and the Trustee or the Paying Agent, as the case
may be, is not prohibited from paying such money to the Securityholders on that
date pursuant to the terms of this Indenture.

          The Company shall pay interest on overdue principal at the rate
specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

          SECTION 4.02.  SEC Reports.  Notwithstanding that the Company may not

be subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, the Company shall file with the Commission and provide the Trustee, Holders
of Securities and, upon request, security analysts of prospective holders of the
Securities with such annual reports and such information, documents and other
reports as are specified in Sections 13 and 15(d) of the Exchange Act and
applicable to a U.S. corporation subject to such Sections, such information,
documents and reports to be so filed and provided at the times specified for the
filing of such information, documents and reports under such Sections; provided,
                                                                       -------- 
however, that the Company shall not be so obligated to file such information,

filings. The Company shall file with the Commission and provide the Trustee,
Holders of Securities and, upon request, security analysts of prospective
holders of the Securities with the information, documents and reports described

          SECTION 4.03.  Limitation on Debt.  The Company shall not, and shall
                         -------------------                                  
not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Debt
unless, after giving pro forma effect to the application of the proceeds
thereof, no Default or Event of Default would occur as a consequence of such
Incurrence or be continuing following such Incurrence and either (a) after
giving effect to the 

 
                                                                              42

Incurrence of such Debt and the application of the proceeds thereof, the
Consolidated Interest Coverage Ratio would be greater than 1.75 to 1.00 if such
Debt is Incurred from the Issue Date through April 15, 2000, and 2.00 to 1.00 if
such Debt is Incurred thereafter or (b) such Debt is Permitted Debt.

     Notwithstanding paragraphs (j) and (k) of the definition of "Permitted
Debt", (a) the Company shall not, and shall not permit any Restricted Subsidiary
to, Incur any Debt pursuant to such paragraphs if the proceeds thereof are used,
directly or indirectly, to Refinance any Subordinated Obligations unless such
Debt shall be subordinated to the Securities to at least the same extent as such
Subordinated Obligations and (b) the Company shall not permit any Restricted
Subsidiary to Incur any Debt pursuant to such paragraphs if the proceeds thereof
are used, directly or indirectly, to Refinance any Subordinated Obligations.

           SECTION 4.04.  Limitation on Restricted Payments. (a) The Company
                          ---------------------------------
shall not make, and shall not permit any Restricted Subsidiary to make, directly
or indirectly, any Restricted Payment if at the time of, and after giving pro
forma effect to, such proposed Restricted Payment,

          (i)   a Default or Event of Default shall have occurred and be
     continuing,

          (ii)  the Company could not Incur at least $1.00 of additional Debt
     pursuant to clause (a) of the first paragraph of Section 4.03 or

          (iii) the aggregate amount of such Restricted Payment and all other
     Restricted Payments declared or made since the Issue Date (the amount of
     any Restricted Payment, if made other than in cash, to be based upon Fair
     Market Value) would exceed an amount equal to the sum of:

               (A)  50% of the aggregate amount of Consolidated Net Income
          accrued during the period (treated as one accounting period) from the
          beginning of the fiscal quarter during which the Issue Date occurs to
          the end of the most recent fiscal quarter ending at least 45 days
          prior to the date of such Restricted Payment (or if the aggregate
          amount of Consolidated Net Income for such period shall be a deficit,
          minus 100% of such deficit),

 
                                                                              43

               (B)  Capital Stock Sale Proceeds,

               (C)  the amount by which Debt of the Company Incurred after the
          Issue Date is reduced on the Company's balance sheet upon the
          conversion or exchange (other than by the Company or a Subsidiary of
          the Company) subsequent to the Issue Date of any Debt (other than
          Subordinated Obligations) of the Company for Capital Stock (other than
          Disqualified Stock) of the Company (less the amount of any cash or
          other Property distributed by the Company or any Restricted Subsidiary
          upon such conversion or exchange), and

               (D)  an amount equal to the sum of (1) the net reduction in
          Investments in any Person other than the Company or a Restricted
          Subsidiary resulting from dividends, repayments of loans or advances
          or other transfers of Property, in each case to the Company or any
          Restricted Subsidiary from such Person, to the extent such dividends,
          repayments or transfers do not increase the amount of Permitted
          Investments permitted to be made pursuant to clause (i) of the
          definition thereof and (2) the portion (proportionate to the Company's
          equity interest in such Unrestricted Subsidiary) of the Fair Market
          Value of the net assets of an Unrestricted Subsidiary at the time such
          Unrestricted Subsidiary is designated a Restricted Subsidiary;
          provided, however, that the foregoing sum shall not exceed, in the
          --------  -------                                                 
          case of any Person, the amount of Investments previously made (and
          treated as a Restricted Payment) by the Company or any Restricted
          Subsidiary in such Person, and

               (E)  $7.5 million.

(b)  Notwithstanding the foregoing limitation, the Company may:

          (i)  pay dividends on its Capital Stock within 60 days of the
     declaration thereof if, on said declaration date, such dividends could have
     been paid in compliance with this Indenture; provided, however, that at the
                                                  --------  -------             
     time of such payment of such dividend, no other Default or Event of Default
     shall have occurred and be continuing (or result therefrom); provided
                                                                  --------

          (ii)   purchase, repurchase, redeem, legally defease, acquire or
     retire for value Capital Stock of the Company or Subordinated Obligations
     in exchange for, or in an amount not in excess of the proceeds of the
     substantially concurrent sale of, Capital Stock of the Company (other than
     Disqualified Stock and other than Capital Stock issued or sold to a
     Subsidiary of the Company or an employee stock ownership plan or trust
     established by the Company or any of its Subsidiaries for the benefit of
     their employees); provided, however, that (1) such purchase, repurchase,
                       --------  -------                                     
     redemption, legal defeasance, acquisition or retirement shall be excluded
     in the calculation of the amount of Restricted Payments and (2) the Capital
     Stock Sale Proceeds from such exchange or sale shall be excluded from the
     calculation pursuant to clause (a)(iii)(B) above;

          (iii)  purchase, repurchase, redeem, legally defease, acquire or
     retire for value any Subordinated Obligations in exchange for, or in an
     amount not in excess of the proceeds of the substantially concurrent sale
     of, Permitted Refinancing Debt; provided, however, that such purchase,
                                     --------  -------                     
     repurchase, redemption, legal defeasance, acquisition or retirement shall

          (iv)   purchase, repurchase, redeem, legally defease, acquire or
     retire for value, or pay dividends or make loans to Holding to enable
     Holding substantially concurrently therewith to purchase, repurchase,
     redeem, legally defease, acquire or retire for value, shares of, or options
     to purchase shares of, common stock of the Company or Holding from
     employees or former employees of the Company, Holding or any of their
     Subsidiaries (or their estates or beneficiaries thereof) upon death,
     disability, retirement or termination pursuant to the terms of the
     agreements (including employment agreements) or plans (or amendments
     thereto) approved by the Board or Directors or the board of directors of
     Holding, as the case may be, under which such individuals purchase or sell,
     or are granted the option to purchase or sell, shares of such common stock;
     provided, however, that (1) the aggregate amount of such purchases,
     --------  -------
     repurchases, redemptions, defeasances, acquisitions or retirements shall
     not exceed $1.0 million in any year or $5.0 million during the term of the
     Securities, except that (x) such amounts shall be increased by the
     aggregate 

 
                                                                              45

     net amount of cash received by the Company after the Issue Date from the
     sale of such shares to, or the exercise of options to purchase such shares
     by, employees of the Company, Holding or any of their Subsidiaries and (y)
     the Company may forgive or return Employee Notes without regard to the
     limitation set forth in clause (iv)(1) above and such forgiveness or return
     shall not be treated as a Restricted Payment for purpose of determining
     compliance with such clause (iv)(1) and (2) such purchases, repurchases,
     defeasances, acquisitions or retirements (but not forgiveness or return of
     Employee Notes) shall be included in the calculation of the amount of
     Restricted Payments;

          (v)  purchase or redeem Subordinated Obligations pursuant to asset
     sale or change of control provisions contained in the governing instrument
     relating thereto; provided, however, that (i) no offer or purchase
                       --------  -------                               
     obligation may be triggered in respect of any such Subordinated Obligation
     unless a corresponding obligation also arises with respect to the
     Securities and (ii) in any event, no repurchase or redemption of any such
     Subordinated Obligation may be consummated unless and until the Company
     shall have satisfied all repurchase obligations with respect to any
     required purchase offer made with respect to the Securities; provided,
                                                                  -------- 
     however, that such purchases or redemptions shall be included in the
     -------                                                             
     calculation of the amount of Restricted Payments; and

          (vi) make payments to Helen Hudson Lovaas pursuant to the Merger
     Agreement in an aggregate amount not to exceed $1.1 million in any fiscal
     year or $3.3 million during the term of the Securities (plus, in each case,
     interest due on the unpaid portion of such required payments in accordance
     with the Merger Agreement); provided, however, that such payments shall be
                                 --------  -------                             
     excluded in the calculation of the amount of Restricted Payments.

          (c)  In computing Consolidated Net Income of the Company under
paragraph (a) above, (1) the Company shall use audited financial statements for
the portions of the relevant period for which audited financial statements are
available on the date of determination and unaudited financial statements and
other current financial data based on the books and records of the Company for
the remaining portion of such period and (2) the Company shall be permitted to
rely in good faith on the financial statements 

 
                                                                              46

and other financial data derived from the books and records of the Company that
are available on the date of determination. If the Company makes a Restricted
Payment which, at the time of the making of such Restricted Payment, would in
the good faith determination of the Company be permitted under the requirements
of this Indenture, such Restricted Payment shall be deemed to have been made in
compliance with this Indenture notwithstanding any subsequent adjustments made
in good faith to the Company's financial statements affecting Consolidated Net
Income of the Company for any period.

          SECTION 4.05.  Limitation on Restrictions on Distributions from
                         ------------------------------------------------
Restricted Subsidiaries.  The Company shall not, and shall not permit any
- ------------------------                                                 
Restricted Subsidiary to, directly or indirectly, create or otherwise cause or
suffer to exist any consensual restriction on the right of any Restricted
Subsidiary to (a) pay dividends, in cash or otherwise, or make any other
distributions on or in respect of its Capital Stock, or pay any Debt or other
obligation owed, to the Company or any other Restricted Subsidiary (except, with
respect to restrictions on dividends of non-cash Property, as permitted pursuant
to clause (ii) of the next sentence), (b) make any loans or advances to the
Company or any other Restricted Subsidiary or (c) transfer any of its Property
to the Company or any other Restricted Subsidiary. The foregoing limitations
will not apply (i) with respect to clauses (a), (b) and (c), to restrictions (A)
in effect on the Issue Date, (B) pursuant to the Credit Facility, (C) relating
to Debt of a Restricted Subsidiary and existing at the time it became a
Restricted Subsidiary if such restriction was not created in connection with or
in anticipation of the transaction or series of transactions pursuant to which
such Restricted Subsidiary became a Restricted Subsidiary or was acquired by the
Company or (D) which result from the Refinancing of Debt Incurred pursuant to an
agreement referred to in clause (i)(A) or (B) above or in clause (ii)(A) or (B)
below, provided such restriction is no less favorable to the holders of
Securities than those under the agreement evidencing the Debt so Refinanced, and
(ii) with respect to clause (c) only, to restrictions (A) relating to Debt that
is permitted to be Incurred and secured without also securing the Securities
equal and ratable treatment pursuant to Section 4.03 and Section 4.10 that limit
the right of the debtor to dispose of the Property securing such Debt, (B)
encumbering Property at the time such Property was acquired by the Company or
any Restricted Subsidiary, so long as such restriction relates solely to the
Property so acquired and was not created in connection with or in 

 
                                                                              47

anticipation of such acquisition, (C) resulting from customary provisions
restricting subletting or assignment of leases or customary provisions in other
agreements that restrict assignment of such agreements or rights thereunder or
(D) customary restrictions contained in asset sale agreements limiting the
transfer of such Property pending the closing of such sale.

          SECTION 4.06.  Limitation on Asset Sales.  (a) The Company shall not,
                         --------------------------                            
and shall not permit any Restricted Subsidiary to, directly or indirectly,
consummate any Asset Sale unless (i) the Company or such Restricted Subsidiary
receives consideration at the time of such Asset Sale at least equal to the Fair
Market Value of the Property subject to such Asset Sale; (ii) at least 75% of
the consideration paid to the Company or such Restricted Subsidiary in
connection with such Asset Sale is in the form of cash or cash equivalents or
the assumption by the purchaser of liabilities of the Company or any Restricted
Subsidiary (other than liabilities that are by their terms subordinated to the
Securities) as a result of which the Company and the Restricted Subsidiaries are
no longer obligated with respect to such liabilities; and (iii) the Company
delivers an Officers' Certificate to the Trustee certifying that such Asset Sale
complies with the foregoing clauses (i) and (ii).

     (b)  The Net Available Cash (or any portion thereof) from Asset Sales may
be applied by the Company or a Restricted Subsidiary, to the extent the Company
or such Restricted Subsidiary elects (or is required by the terms of any Debt):
(i) to prepay, repay, legally defease or purchase Senior Debt of the Company or
any Restricted Subsidiary (excluding, in any such case, Disqualified Stock and
Debt owed to the Company or an Affiliate of the Company); or (ii) to reinvest in
Additional Assets (including by means of an Investment in Additional Assets by a
Restricted Subsidiary with Net Available Cash received by the Company or another
Restricted Subsidiary); provided, however, that in connection with any
                        --------  -------                             
prepayment, repayment, legal defeasance or purchase of Debt pursuant to clause
(i) above, the Company or such Restricted Subsidiary shall retire such Debt and
shall cause the related loan commitment (if any) to be permanently reduced by an
amount equal to the principal amount so prepaid, repaid, legally defeased or
purchased.

     (c)  Any Net Available Cash from an Asset Sale not applied in accordance
with the preceding paragraph within twelve months from the date of the receipt
of such Net Available Cash shall constitute "Excess Proceeds." When the
aggregate amount of Excess Proceeds exceeds $10.0 million 

 
                                                                              48

(taking into account income earned on such Excess Proceeds, if any), the Company
will be required to make an offer to purchase (the "Prepayment Offer") the
Securities which offer shall be in the amount of the Excess Proceeds, on a pro
rata basis according to principal amount, at a purchase price equal to 100% of
the principal amount thereof plus accrued and unpaid interest thereon, if any,
to the purchase date (subject to the right of holders of record on the relevant
record date to receive interest due on the relevant interest payment date) in
accordance with the procedures (including prorating in the event of
oversubscription) set forth in this Indenture. To the extent that any portion of
the amount of Net Available Cash remains after compliance with the preceding
sentence and provided that all holders of Securities have been given the
opportunity to tender their Securities for purchase in accordance with this
Indenture, the Company or such Restricted Subsidiary may use such remaining
amount for any purpose permitted by this Indenture and the amount of Excess
Proceeds will be reset to zero.

          (d)(1)  Within five business days after the Company is obligated to
make a Prepayment Offer as described in the preceding paragraph, the Company
shall send a written notice, by first-class mail, to the Trustee and the Holders
of Securities (the "Prepayment Offer Notice"), accompanied by such information
regarding the Company and its Subsidiaries as the Company in good faith believes
will enable such Holders to make an informed decision with respect to such
Prepayment Offer. The Prepayment Offer Notice shall state (i) that the Company
is offering to purchase Securities pursuant to the provisions of this Indenture,
(ii) that any Security (or any portion thereof) accepted for payment (and duly
paid on the Purchase Date) pursuant to the Prepayment Offer shall cease to
accrue interest on the Purchase Date, (iii) that any Securities (or portions
thereof) not properly tendered shall continue to accrue interest, (iv) the
purchase price and purchase date, which shall be, subject to any contrary
requirements of applicable law, a Business Day no earlier than 30 days nor later
than 60 days after the date the Prepayment Offer Notice is mailed (the "Purchase
Date"), (v) the aggregate principal amount of Securities to be purchased, (vi) a
description of the procedures which Holders of Securities must follow in order
to tender their Securities and the procedures that Holders of Securities must
follow in order to withdraw an election to tender their Securities for payment
and (vii) all other instructions and materials necessary to enable Holders to
tender Securities pursuant to the Prepayment Offer.

 
                                                                              49

          (2)  Not later than the date upon which written notice of a Prepayment
Offer is delivered to the Trustee as provided above, the Company shall deliver
to the Trustee an Officers' Certificate as to (i) the amount of the Prepayment
Offer (the "Offer Amount"), (ii) the allocation of the Net Available Cash from
the Asset Sales pursuant to which such Prepayment Offer is being made and (iii)
the compliance of such allocation with the provisions of Section 4.06(a). On
such date or prior to the Purchase Date, the Company shall also irrevocably
deposit with the Trustee or with the Paying Agent (or, if the Company or a
Wholly Owned Subsidiary is the Paying Agent, shall segregate and hold in trust)
in cash or Temporary Cash Investments, maturing on the last 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 Prepayment Offer remains open (the "Offer Period"), the
Company shall deliver to the Trustee for cancelation the Securities or portions
thereof which have been properly tendered to and are to be accepted by the
Company. The Trustee or the Paying Agent 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
Company to the Trustee is less than the Offer Amount, the Trustee or the Paying
Agent shall deliver the excess to the Company immediately after the expiration
of the Offer Period for application in accordance with this Section.

          (3)  Holders electing to have a Security purchased shall be required
to surrender the Security, with an appropriate form duly completed, to the
Company or its agent at the address specified in the notice at least three
Business Days prior to the Purchase Date. Holders shall be entitled to withdraw
their election if the Trustee or the Company 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
Company shall select the Securities to be purchased on a pro rata basis (with
such adjustments as may be deemed appropriate by the Company so that only
Securities in denominations of $1,000, or integral multiples thereof, shall be
purchased). Holders whose Securities are purchased 

 
                                                                              50

only in part shall be issued new Securities equal in principal amount to the
unpurchased portion of the Securities surrendered.

          (4)  At the time the Company delivers Securities to the Trustee which
are to be accepted for purchase, the Company shall also deliver an Officers'
Certificate stating that such Securities are to be accepted by the Company
pursuant to and in accordance with the terms of this Section 4.06. A Security
shall be deemed to have been accepted for purchase at the time the Trustee or
the Paying Agent mails or delivers payment therefor to the surrendering Holder.

          (e)  The Company 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 as described
above. To the extent that the provisions of any securities laws or regulations
conflict with the provisions relating to the Prepayment Offer, the Company shall
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations described above by virtue thereof.

          SECTION 4.07.  Limitation on Transactions with Affiliates.  (a) The
                         -------------------------------------------         
Company shall not, and shall not permit any Restricted Subsidiary to, directly
or indirectly, conduct any business or enter into or suffer to exist any
transaction or series of transactions (including the purchase, sale, transfer,
assignment, lease, conveyance or exchange of any Property or the rendering of
any service) with, or for the benefit of, any Affiliate of the Company (an
"Affiliate Transaction"), unless (a) the terms of such Affiliate Transaction are
(i) set forth in writing, (ii) in the interest of the Company or such Restricted
Subsidiary, as the case may be, and (iii) no less favorable to the Company or
such Restricted Subsidiary, as the case may be, than those that could be
obtained in a comparable arm's-length transaction with a Person that is not an
Affiliate of the Company, (b) if such Affiliate Transaction involves aggregate
payments or value in excess of $2.5 million, the Board of Directors (including a
majority of the disinterested members of the Board of Directors, if any)
approves such Affiliate Transaction and, in its good faith judgment, believes
that such Affiliate Transaction complies with clauses (a) (ii) and (iii) of this
paragraph as evidenced by a Board Resolution promptly delivered to the Trustee
and (c) if such Affiliate Transaction involves aggregate payments or value in
excess of $5.0 million, the 

 
                                                                              51

Company obtains a written opinion from an Independent Appraiser to the effect
that the consideration to be paid or received in connection with such Affiliate
Transaction is fair, from a financial point of view, to the Company or such
Restricted Subsidiary, as the case may be and a copy of the written opinion is

          (i)    any transaction or series of transactions between the Company
     and one or more Restricted Subsidiaries or between two or more Restricted
     Subsidiaries in the ordinary course of business; provided that no more than
                                                      --------

     as the Board of Directors in good faith shall have approved the terms
     thereof and deemed the services theretofore or thereafter to be performed
     for such compensation to be fair consideration therefor;

          (iv)   loans and advances to employees made in the ordinary course of
     business and consistent with the past practices of the Company or such
     Restricted Subsidiary, as the case may be; provided, that such loans and

                                                                   --------     
     the Company may receive Employee Notes in an aggregate principal amount not
     in excess of $1.0 million at any one time outstanding;

          (vii)  the payment of dividends in kind in respect of (i) the Mirror
     Preferred Stock or (ii) any other Preferred Stock issued in compliance with
     this Section; and

          (viii) a proportionate split of, or a common stock dividend payable
     on, the common stock of the Company.

          SECTION 4.08.  Limitation on Issuance or Sale of Capital Stock of
                         --------------------------------------------------
Restricted Subsidiaries.  The Company shall not (a) sell, pledge, hypothecate or
- ------------------------                                                        
otherwise dispose of any shares of Capital Stock of a Restricted Subsidiary or
(b) permit any Restricted Subsidiary to, directly or indirectly, issue or sell
or otherwise dispose of any shares of its Capital Stock, other than (i)
directors' qualifying shares, (ii) to the Company or a Wholly Owned Subsidiary
or (iii) a disposition of 100% of the shares of Capital Stock of a Restricted
Subsidiary that complies with Section 4.06.

          SECTION 4.09.  Repurchase at the Option of Holders Upon a Change of
                         ----------------------------------------------------
Control.  (a)  Upon the occurrence of a Change of Control, each holder of
- --------                                                                 
Securities shall have the right to require the Company to repurchase all or any
part of such holder's Securities pursuant to the offer described below (the
"Change of Control Offer") at a purchase price (the "Change of Control Purchase
Price") equal to 101% of the principal amount thereof, plus accrued and unpaid
interest thereon, if any, to the purchase date (subject to the right of holders
of record on the relevant record date to receive interest due on the relevant
interest payment date).

          (b)  Within 30 days following any Change of Control, the Company shall
(a) cause a notice of the Change of Control Offer to be sent at least once to
the Dow Jones News Service or similar business news service in the United States

Control Offer is being made pursuant to this Section and that all Securities
timely tendered will be accepted for payment; (ii) the Change of Control
Purchase Price and the purchase date, which shall be, subject to any contrary
requirements of applicable law, a business day no earlier than 30 days nor later

respect to pro forma historical income, cash flow and capitalization after
giving effect to the Change of 

 
                                                                              53

Control); (iv) that any Security (or portion thereof) accepted for payment (and
duly paid on the Change of Control Payment Date) pursuant to the Change of
Control Offer shall cease to accrue interest on the Change of Control Payment
Date; (v) that any Securities (or portions thereof) not properly tendered shall
continue to accrue interest; (vi) the procedures that Holders of Securities must
follow in order to tender their Securities (or portions thereof) for payment and
the procedures that Holders of Securities must follow in order to withdraw an
election to tender Securities (or portions thereof) for payment; and (vii) all
other instructions and materials necessary to enable Holders to tender
Securities pursuant to the Change of Control Offer.

          (c)  Holders electing to have a Security purchased shall be required
to surrender the Security, with an appropriate form duly completed, to the
Company or its agent at the address specified in the notice at least three
Business Days prior to the Change of Control Payment Date. Holders shall be
entitled to withdraw their election if the Trustee or the Company receives not
later than one Business Day prior to the Change of Control Payment 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. Holders whose Securities are purchased only in part
shall be issued new Securities equal in principal amount to the unpurchased
portion of the Securities surrendered.

          (d)  On or prior to the Change of Control Payment Date, the Company
shall irrevocably deposit with the Trustee or with the Paying Agent (or, if the
Company or any of its Wholly Owned Subsidiaries is acting as the Paying Agent,
segregate and hold in trust) in cash an amount equal to the Change of Control
Payment payable to the Holders entitled thereto, to be held for payment in
accordance with the provisions of this Section.

          (e)  On the Change of Control Payment Date, the Company shall deliver
to the Trustee the Securities or portions thereof which have been properly
tendered to and are to be accepted by the Company for payment. The Trustee or
the Paying Agent shall, on the Change of Control Payment Date, mail or deliver
payment to each tendering Holder of the Change of Control Payment. In the event
that the aggregate Change of Control Payment is less than the amount delivered
by the Company to the Trustee or the Paying Agent,

 
                                                                              54

the Trustee or the Paying Agent, as the case may be, shall deliver the excess to
the Company immediately after the Change of Control Payment Date.

          (f)  At the time the Company delivers Securities to the Trustee which
are to be accepted for purchase, the Company shall also deliver an Officers'
Certificate stating that such Securities are to be accepted by the Company
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 or the
Paying Agent mails or delivers payment therefor to the surrendering Holder.
Unless the Company defaults in the payment of the Change of Control Payment,
each Security accepted for payment pursuant to the Change of Control Offer shall
cease to accrue interest on and after the Change of Control Payment Date.

          (g)  The Company shall comply, to the extent applicable, with the
requirements of Rule 14(e) under the Exchange Act and any other securities laws
or regulations thereunder in connection with the purchase 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 Company 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 4.10.  Limitation on Liens.  The Company shall not, and shall
                         --------------------                                  
not permit any Restricted Subsidiary to, directly or indirectly, Incur or suffer
to exist, any Lien (other than Permitted Liens) upon any of its Property
(including Capital Stock of a Restricted Subsidiary), whether owned at the Issue
Date or thereafter acquired, or any interest therein or any income or profits
therefrom, unless (i) if such Lien secures Subordinated Debt, the Securities are
secured on an equal and ratable basis with such Debt and (ii) if such Lien
secures Subordinated Obligations, such Lien shall be subordinated to a Lien
securing the Securities in the same Property as that securing such Lien to the
same extent as such Subordinated Obligations are subordinated to the Securities.

          SECTION 4.11.  Compliance Certificate.  The Company shall deliver to
                         -----------------------                              
the Trustee within 120 days after the end of each fiscal year of the Company an
Officers' Certificate stating that in the course of the performance by the
signers of their duties as Officers of the Company they would normally have
knowledge of any Default and whether or 

 
                                                                              55

not the signers know of any Default that occurred during such period. If they
do, the certificate shall describe the Default, its status and what action the
Company is taking or proposes to take with respect thereto. The Company also
shall comply with TIA (S) 314(a)(4).

          SECTION 4.12.  Further Instruments and Acts.  Upon request of the
                         -----------------------------                     
Trustee, the Company shall execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more
effectively the purpose of this Indenture.

          SECTION 4.13.  Designation of Restricted and Unrestricted
                         ------------------------------------------
Subsidiaries.  The Board of Directors may designate any Subsidiary of the
- -------------                                                            
Company which is not designated as a Restricted Subsidiary under the 9 1/8%
Indenture to be an Unrestricted Subsidiary if (a) the Subsidiary to be so
designated does not own any Capital Stock or Debt of, or own or hold any Lien on
any Property of, the Company or any other Restricted Subsidiary, (b) the
Subsidiary to be so designated is not obligated under any Debt, Lien or other
obligation that, if in default, would result (with the passage of time or notice
or otherwise) in a default on any Debt of the Company or of any Restricted
Subsidiary and (c) either (i) the Subsidiary to be so designated has total
assets of $1,000 or less or (ii) such designation is effective immediately upon
such entity becoming a Subsidiary of the Company. Unless so designated as an
Unrestricted Subsidiary, any Person that becomes a Subsidiary of the Company
will be classified as a Restricted Subsidiary; provided, however, that such
                                               --------  -------           
Subsidiary shall not be designated a Restricted Subsidiary and shall be
automatically classified as an Unrestricted Subsidiary if either of the
requirements set forth in clauses (x) and (y) of the immediately following
paragraph will not be satisfied after giving pro forma effect to such
classification. Except as provided in the first sentence of this paragraph, no
Restricted Subsidiary may be redesignated as an Unrestricted Subsidiary.

     The Board of Directors may designate any Unrestricted Subsidiary to be a
Restricted Subsidiary if, immediately after giving pro forma effect to such
designation, (x) the Company could Incur at least $1.00 of additional Debt
pursuant to clause (a) of the first paragraph of Section 4.03 and (y) no Default
or Event of Default shall have occurred and be continuing or would result
therefrom.

     Any such designation or redesignation by the Board of Directors will be
evidenced to the Trustee by filing with 

 
                                                                              56

the Trustee a Board Resolution giving effect to such designation or
redesignation and an Officers' Certificate (a) certifying that such designation
or redesignation complies with the foregoing provisions and (b) giving the
effective date of such designation or redesignation, such filing with the
Trustee to occur within 45 days after the end of the fiscal quarter of the
Company in which such designation or redesignation is made (or, in the case of a
designation or redesignation made during the last fiscal quarter of the
Company's fiscal year, within 90 days after the end of such fiscal year).

          SECTION 4.14.  Limitation on Holding's Business. The Company shall use
                         ---------------------------------                      
its best efforts to cause Holding not to, directly or indirectly, engage in any
business or activity other than the ownership of Capital Stock of the Company
and business activities incidental thereto.

          SECTION 5.01.  When Company May Merge or Transfer Assets.  (a)  The
                         ------------------------------------------          
Company shall not merge, consolidate or amalgamate with or into any other Person
(other than a merger of a Wholly Owned Subsidiary into the Company) or sell,
transfer, assign, lease, convey or otherwise dispose of all or substantially all
its Property in any one transaction or series of transactions unless:  (i) the
Company shall be the surviving Person (the "Surviving Person") or the Surviving
Person (if other than the Company) formed by such merger, consolidation or
amalgamation or to which such sale, transfer, assignment, lease, conveyance or
disposition is made shall be a corporation organized and existing under the laws
of the United States of America, any State thereof or the District of Columbia;
(ii) the Surviving Person (if other than the Company) expressly assumes, by
supplemental indenture in form satisfactory to the Trustee, executed and
delivered to the Trustee by such Surviving Person, the due and punctual payment
of the principal of, and premium, if any, and interest on, all the Securities,
according to their tenor, and the due and punctual performance and observance of
all the covenants and conditions of this Indenture to be performed by the
Company; (iii) in the case of a sale, transfer, assignment, lease, conveyance or
other disposition of all or substantially all the Property of the Company, such
Property shall have been transferred as an entirety or virtually as an entirety
to one Person; (iv) immediately before and after giving effect 

 
                                                                              57

to such transaction or series of transactions on a pro forma basis (and
treating, for purposes of this clause (iv) and clauses (v) and (vi) below, any
Debt which becomes, or is anticipated to become, an obligation of the Surviving
Person or any Restricted Subsidiary as a result of such transaction or series of
transactions as having been Incurred by the Surviving Person or such Restricted
Subsidiary at the time of such transaction or series of transactions), no
Default or Event of Default shall have occurred and be continuing; (v)
immediately after giving effect to such transaction or series of transactions on
a pro forma basis, the Company or the Surviving Person, as the case may be,
would be able to Incur at least $1.00 of additional Debt under clause (a) of the
first paragraph of Section 4.03; provided, however, that this clause (v) shall
                                 --------  -------                            
not apply to a merger between the Company and a Wholly Owned Subsidiary of the
Company or Holding incorporated in another state of the United States solely for
the purpose of reincorporating the Company as long as the total amount of Debt
of the Company and its Restricted Subsidiaries is not increased as a result
thereof; and (vi) the Company shall deliver, or cause to be delivered, to the
Trustee, in form and substance reasonably satisfactory to the Trustee, an
Officers' Certificate and an Opinion of Counsel, each stating that such
transaction and the supplemental indenture, if any, in respect thereto comply
with this Section and that all conditions precedent herein provided for relating
to such transaction have been satisfied and that the supplemental indenture, if
any, has been duly authorized, executed and delivered and is enforceable against
the Surviving Person.

          (b)  The Surviving Person shall succeed to, and be substituted for,
and may exercise every right and power of the Company under this Indenture, but
the predecessor Company in the case of a sale, transfer, assignment, lease,
conveyance or other disposition shall not be released from the obligation to pay
the principal of, and premium, if any, and interest on, the Securities.

          SECTION 6.01.  Events of Default.  The following events shall be
                         ------------------                               
"Events of Default":

          (1)  the Company defaults in any payment of inter  est on the
     Securities when the same becomes due and payable, whether or not such
     payment shall be 

 
                                                                              58

     days;

          (2)  the failure to make the payment of any principal of or premium,
     if any, on any of the Securities when the same become due and payable at
     its Stated Maturity, upon acceleration, redemption, optional redemption,
     upon required repurchase or otherwise, whether or not such payment shall be
     prohibited by Article 10;

          (3)  the Company fails to comply with Article 5;

          (4)  the Company fails to comply with any other covenant or agreement
     in the Securities or in this Indenture (other than a failure which is the
     subject of the foregoing clause (1), (2) or (3)), or Holding engages at any
     time, directly or indirectly, in any business or activity other than
     ownership of Capital Stock of the Company and business activities
     incidental thereto, and continuance of such failure, or occurrence, for a
     period of 30 days after the notice specified below;

          (5)  default by the Company or any Restricted Subsidiary under any
     Debt of the Company or any Restricted Subsidiary which results in
     acceleration of the stated maturity of such Debt, or the failure to pay
     such Debt at final maturity, in an aggregate amount greater than $7.5
     million or its foreign currency equivalent at the time;

          (6)  any judgment or judgments for the payment of money in an
     aggregate amount in excess of $7.5 million (or its foreign currency
     equivalent at the time) shall be rendered against the Company or any
     Restricted Subsidiary and shall not be waived, satisfied or discharged for
     any period of 30 consecutive days during which a stay of enforcement shall
     not be in effect;

          (7)  the Company 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;

 
                                                                              59

               (C)  consents to the appointment of a Custodian of it or for any
          substantial part of its property; or

               (D)  makes a general assignment for the benefit of its creditors;

     or takes any comparable action under any foreign laws relating to
     insolvency;

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

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

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

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

               (D)  grants any similar relief under any foreign laws;

     and in each such case the order or decree remains unstayed and in effect
     for 60 days; or

          The foregoing shall constitute Events of Default whatever the reason
for any such Event of Default and whether it is voluntary or involuntary or is
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body.

          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 (4) is not an Event of Default until the
Trustee or the Holders of at least 25% in aggregate principal amount of the
outstanding Securities notify the Company (and in the case of such notice by
Holders, the Trustee) in writing of such Default and the Company does not cure
such Default within the time specified after receipt of such notice.  Such
notice must specify the 

 
                                                                              60

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

          The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default and event which with the giving of notice or the lapse of
time would become an Event of Default, its status and what action the Company is
taking or proposes to take with respect thereto.

          SECTION 6.02.  Acceleration.  If an Event of Default (other than an
                         -------------                                       
Event of Default specified in Section 6.01(7) or (8)) occurs and is continuing,
the Trustee by notice to the Company, or the Holders of at least 25% in
aggregate principal amount of the Securities then outstanding by notice to the
Company and the Trustee, may declare the principal amount of all the Securities
then outstanding, plus accrued but unpaid interest to be due and payable.  Upon
such a declaration, such principal shall be due and payable immediately.  If an
Event of Default specified in Section 6.01(7) or (8) occurs, the principal of
the Securities shall automatically and without any action by the Trustee or any
Holder, become immediately due and payable.  The Holders of a majority in
aggregate principal amount of the outstanding Securities by notice to the
Trustee and the Company may rescind and annul any declaration of acceleration 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, premium or interest that has become due solely because of the
acceleration. No such rescission shall affect any subsequent Default or impair
any right consequent thereto.

          SECTION 6.03.  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.

          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.

 
                                                                              61

          SECTION 6.04.  Waiver of Defaults.  The Holders of a majority in
                         -------------------                              
aggregate principal amount of the Securities by notice to the Trustee may waive,
on behalf of the Holders of all outstanding Securities, a past or an existing
Default and its consequences or compliance with any provision of this Indenture
or the Securities except (i) a Default in the payment of the principal of or
interest on a Security or (ii) a Default in respect of a provision that under
Section 9.02 cannot be amended without the consent of each Securityholder
affected.  When a Default is waived, it is deemed cured and not to have occurred
for every purpose of this Indenture and the Securities, but no such waiver shall
extend to any subsequent or other Default or impair any consequent right.

          SECTION 6.05.  Control by Majority.  The Holders of a majority in
                         --------------------                              
aggregate 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 the Trustee with respect to the
Securities.  However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture or, subject to Section 7.01, 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 reasonable indemnity against all losses and
expenses caused by taking or not taking such action.

          SECTION 6.06.  Limitation on Suits.  A Securityholder may not pursue
                         --------------------                                  
any remedy with respect to this Indenture or the Securities unless:

          (1) such Holder shall have previously given to the Trustee written
     notice of a continuing Event of Default;

          (2) the Holders of at least 25% in aggregate principal amount of the
     Securities then outstanding shall have made a written request, and such
     Holder of or Holders shall have offered reasonable indemnity, to the
     Trustee to pursue such proceeding as trustee; and

          (3) the Trustee has failed to institute such proceeding and has not
     received from the Holders of at least a majority in aggregate principal
     amount of the Securities outstanding a direction inconsistent with 

 
                                                                              62

     such request, within 60 days after such notice, request and offer.

          The foregoing limitations on the pursuit of remedies by a
Securityholder shall not apply to a suit instituted by a Holder of Securities
for the enforcement of payment of the principal of or interest on such Security
on or after the applicable due date specified in such Security. 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 6.07.  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 this 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 6.08.  Collection Suit by Trustee.  If an Event of Default
                         ---------------------------                        
specified in Section 6.01(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
Company for the whole amount then due and owing (together with interest on any
unpaid interest to the extent lawful) and the amounts provided for in Section
7.07.

          SECTION 6.09.  Trustee May File Proofs of Claim. The Trustee may file
                         ---------------------------------                     
such proofs of claim and other papers or documents 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 Company, 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, is empowered to participate as a member,
voting or otherwise, of any official committee of creditors appointed in such
matter, 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 reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and its counsel, and any
other amounts due the Trustee under Section 7.07.

 
                                                                              63

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

          SECTION 6.10.  Priorities.  If the Trustee collects any money or
                         -----------                                       
property pursuant to this Article 6, it shall pay out the money or property in
the following order:

          FIRST:  to the Trustee for amounts due under Section 7.07;

          SECOND:  to holders of Senior Debt of the Company to the extent
     required by Article 10;

          THIRD:  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

          FOURTH:  to the Company.

          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 Company shall mail to each Securityholder and the Trustee a notice
that states the record date, the payment date and amount to be paid.

          SECTION 6.11.  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, the Company, a suit by a Holder pursuant to Section 6.07 or a suit by
Holders of more than 10% in aggregate principal amount of the Securities.

          SECTION 6.12.  Waiver of Stay or Extension Laws. The Company (to the
                         ---------------------------------                    
extent it may lawfully do so) shall not 

 
                                                                              64

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 Company (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.

                                   ARTICLE 7

                                    Trustee
                                    -------

          SECTION 7.01.  Duties of Trustee.  (a)  If an Event of Default has
                         ------------------                                 
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the conduct of such Person's own affairs.

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

          (1) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture and no implied covenants or
     obligations shall be read into this Indenture against the Trustee; 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, but shall not be obligated to verify the contents thereof.

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

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

 
                                                                              65

          (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
     received by it pursuant to Section 6.05.

          (d)  Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section.

          (e)  The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

          (f)  Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

          (g)  No provision of this Indenture 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 of its
rights or powers, if it shall have reasonable grounds to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

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

          SECTION 7.02.  Rights of Trustee.  (a)  The Trustee may rely on any
                         ------------------                                  
document reasonably believed by it to be genuine and to have been signed or
presented by the proper person.  The Trustee need not investigate any fact or
matter stated in the document.

          (b)  Before the Trustee acts or refrains from acting, it may require
an Officers' Certificate or an Opinion of Counsel.  The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on the
Officers' Certificate or Opinion of Counsel.

          (c)  The Trustee may act through agents and shall not be responsible
for the misconduct or negligence of any 

 
                                                                              66

agent (other than an agent who is an employee of the Trustee) appointed with due
care.

          (d)  The Trustee shall not be liable for any action it takes or omits
to take in good faith which it reasonably believes to be authorized or within
its rights or powers; provided, however, that the Trustee's conduct does not
                      --------  -------                                     
constitute wilful misconduct or negligence.

          (e)  The Trustee may consult with counsel, and the written advice or
written opinion of counsel with respect to legal matters relating to this
Indenture and the Securities shall be full and complete authorization and
protection from liability in respect to any action taken, omitted or suffered by
it hereunder in good faith and in accordance with such advice or opinion of such
counsel.

          (f)  Unless otherwise specifically provided herein, any demand,
request, direction or notice from the Company shall be sufficient if signed by
an Officer of the Company.

          (g)  The Company, the Paying Agent, the Registrar, the Trustee and any
agent of the Company, the Paying Agent, the Registrar or the Trustee may deem
and treat the Person in whose name any Security is registered as the absolute
owner of such Security for the purpose of receiving payment of or on account of
the principal of and, subject to the provisions of this Indenture, interest on
such Security and for all other purposes; and neither the Company, the Paying
Agent, the Registrar nor the Trustee nor any agent of the Company, the Paying
Agent, the Registrar or the Trustee shall be affected by any notice to the
contrary.

          SECTION 7.03.  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 Company or its Affiliates with the same rights
it would have if it were not Trustee.  Any Paying Agent, Registrar or co-
registrar may do the same with like rights. However, the Trustee must comply
with Sections 7.10 and 7.11.

          SECTION 7.04.  Trustee's Disclaimer.  The Trustee shall not be
                         ---------------------                          
responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Securities, it shall not be accountable for the Company's
use of the proceeds from the Securities, and it shall not be responsible for any
statement of the Company in this Indenture or in any document issued in
connection with the 

 
                                                                              67

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

          SECTION 7.05.  Notice of Defaults.  If a Default occurs and is
                         -------------------                            
continuing and if it is known to the employees of the Trustee with
responsibility for the Securities, the Trustee shall mail to each Securityholder
notice of the Default within 90 days after it is known to such employees of the
Trustee or written notice of it is received by the Trustee.  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 so long as a committee of its Trust Officers in
good faith determines that withholding the notice is in the interests of
Securityholders.

          SECTION 7.06.  Reports by Trustee to Holders.  As promptly as
                         ------------------------------                
practicable after each May 15 beginning with May 15, 1999, and in any event
prior to July 15 in each year, the Trustee shall mail to each Securityholder a
brief report dated as of May 15 each year that complies with TIA (S) 313(a), if
and to the extent required by said subsection. The Trustee also shall comply
with TIA (S) 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 (if any) on which the
Securities are listed. The Company agrees to notify promptly the Trustee
whenever the Securities become listed on any stock exchange and of any delisting
thereof.

          SECTION 7.07.  Compensation and Indemnity.  The Company 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 Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it,
including costs of collection, 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, counsel, accountants and
experts.  The Company shall indemnify the Trustee against any and all loss,
liability or expense (including reasonable attorneys' fees, but excluding any
franchise taxes imposed on the Trustee and any taxes based on the income of the
Trustee) incurred by it in connection with the acceptance and administration of
this trust, including the reasonable costs and expenses of enforcing this
Indenture against the Company (including Section 7.07) and of defending itself
against any claim (including any claim asserted by the Company) and the

 
                                                                              68

performance of its duties hereunder.  The Trustee shall notify the Company
promptly of any claim for which it may seek indemnity.  Failure by the Trustee
to so notify the Company shall not relieve the Company of its obligations
hereunder, except to the extent such failure shall have materially prejudiced
the Company.  The Company shall defend the claim and the Trustee shall cooperate
in the defense. If the Trustee is advised by counsel in writing that it may have
available to it defenses which are in conflict with the defenses available to
the Company, then the Trustee may have separate counsel and the Company shall
pay the reasonable fees and expenses of such counsel.  The Company need not
reimburse any expense or indemnify against any loss, liability or expense
incurred by the Trustee or any of its agents, counsel, accountants or experts
which is judicially determined to be the result of the Trustee's or any such
agent's, counsel's, accountant's or expert's own wilful misconduct, negligence
or bad faith.  The Company need not pay for any settlement made by the Trustee
without the Company's consent, such consent not to be unreasonably withheld or
delayed.

          The Trustee's right to receive payment of any amounts due under this
Section 7.07 shall not be subordinated to any other liability or indebtedness of
the Company (even though the Securities may be so subordinated).

          To secure the Company'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 other than money or property held in trust to pay
principal of and interest on particular Securities.

          The Company's payment obligations pursuant to this Section shall
survive the discharge of this Indenture.  When the Trustee incurs expenses after
the occurrence of a Default specified in Section 6.01(7) or (8), the expenses
are intended to constitute expenses of administration under the Bankruptcy Law.

          SECTION 7.08.  Replacement of Trustee.  The Trustee may resign at any
                         -----------------------                               
time by so notifying the Company. The Holders of a majority in aggregate
principal amount of the Securities may remove the Trustee by so notifying the
Trustee and may appoint a successor Trustee.  The Company shall remove the
Trustee if:

          (1) the Trustee fails to comply with Section 7.10;

          (2) the Trustee is adjudged bankrupt or insolvent;

 
                                                                              69

          (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, is removed by the Company or by the Holders of
a majority in aggregate principal amount of the Securities and such Holders do
not reasonably promptly appoint a successor Trustee, 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 Company shall promptly appoint a
successor Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company.  Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture.  The successor Trustee shall mail a notice of its
succession to Securityholders.  The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.07.

          If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of 10% in aggregate 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 7.10, any Securityholder
who has been a bona fide Holder of a Security for at least six months may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

          Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 7.07 shall continue for the
benefit of the retiring Trustee.

          SECTION 7.09.  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 or banking
association without any further act shall be the successor Trustee.

 
                                                                              70

          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
such 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 7.10.  Eligibility; Disqualification.  The Trustee shall at
                         ------------------------------                      
all times satisfy the requirements of TIA (S) 310(a). 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
(S) 310(b), subject to the penultimate paragraph thereof; provided, however,
                                                          --------  ------- 
that there shall be excluded from the operation of TIA (S) 310(b)(1) any
indenture or indentures under which other securities or certificates of interest
or participation in other securities of the Company are outstanding if the
requirements for such exclusion set forth in TIA (S) 310(b)(1) are met.

          SECTION 7.11.  Preferential Collection of Claims Against Company.  The
                         --------------------------------------------------     
Trustee shall comply with TIA (S) 311(a), excluding any creditor relationship
listed in TIA (S) 311(b).  A Trustee who has resigned or been removed shall be

                       Discharge of Indenture; Defeasance
                       ----------------------------------

          SECTION 8.01.  Discharge of Liability on Securities; Defeasance.  (a)
                         -------------------------------------------------      
When (i) the Company delivers to the Trustee all outstanding Securities (other
than Securities replaced pursuant to Section 2.07) for cancelation or (ii) all
outstanding Securities have become due and payable, whether at maturity or as a
result of the mailing of a notice of redemption pursuant to Article 3 and the
Company irrevocably deposits with the Trustee funds sufficient to pay at
maturity or upon redemption all outstanding Securities, including interest
thereon to maturity or such redemption date (other than Securities replaced
pursuant to 

 
                                                                              71

Section 2.07), and if in either case the Company pays all other sums payable
hereunder by the Company, then this Indenture shall, subject to Sections
8.01(c), cease to be of further effect. The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of the Company
accompanied by an Officers' Certificate and an Opinion of Counsel and at the
cost and expense of the Company.

          (b)  Subject to Sections 8.01(c) and 8.02, the Company at any time may
terminate (i) all its obligations under the Securities and this Indenture
("legal defeasance option") or (ii) its obligations under Sections 4.02, 4.03,
4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.13 and 4.14 the operation of
Sections 6.01(4) (to the extent relating to such other Sections), 6.01(5),
6.01(6), 6.01(7) and 6.01(8) (but, in the case of Sections 6.01(6) and (7), with
respect only to Significant Subsidiaries), its obligations under Sections
5.01(a)(iv), 5.01(a)(v) and the related operation of Section 6.01(3) ("covenant
defeasance option").  The Company may exercise its legal defeasance option
notwithstanding its prior exercise of its covenant defeasance option.

          If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of an Event of Default with respect
thereto.  If the Company exercises its covenant defeasance option, payment of
the Securities may not be accelerated because of an Event of Default specified
in Sections 6.01(3) and 6.01(4) (with respect to the provisions of Articles 4
and 5 referred to in the immediately preceding paragraph) and Sections 6.01(5),
6.01(6), 6.01(7) and 6.01(8) (but, in the case of Sections 6.01(6) and (7), with
respect only to Significant Subsidiaries).

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

          (c)  Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.04, 2.05, 2.06, 2.07, 7.07, 7.08, 8.05 and 8.06 and
Appendix A shall survive until the Securities have been paid in full.
Thereafter, the Company's obligations in Sections 7.07 and 8.05 shall survive.

 
                                                                              72

          SECTION 8.02.  Conditions to Defeasance.  The Company may exercise its
                         -------------------------                              
legal defeasance option or its covenant defeasance option only if:

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

          (2) the Company 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 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 Default specified in Section 6.01(6) or (7) with respect to the
     Company occurs which is continuing at the end of the period;

          (4) the deposit does not constitute a default under any other material
     agreement binding on the Company and is not prohibited by Article 10;

          (5) the Company 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 company under the Investment Company
     Act of 1940;

          (6) in the case of the legal defeasance option, the Company shall have
     delivered to the Trustee an Opinion of Counsel stating that (i) the Company
     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 Securityholders 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;

 
                                                                              73

          (7) in the case of the covenant defeasance option, the Company 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 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 Company 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
     8 have been complied with.

          Opinions of Counsel required to be delivered to the Trustee may have
assumptions customary for opinions of the type required and counsel delivering
such Opinions of Counsel may rely on certificates of the Company or government
or other officials customary for opinions of the type required, including
certificates certifying as to matters of fact, including that various financial
covenants have been complied with.

          Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article 3.

          SECTION 8.03.  Application of Trust Money.  The Trustee shall hold in
                         ---------------------------                           
trust money or U.S. Government Obligations deposited with it pursuant to this
Article 8.  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 10.

          SECTION 8.04.  Repayment to Company.  The Trustee and the Paying Agent
                         ---------------------                                  
shall promptly turn over to the Company 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 Company upon request any money held by them for
the payment of principal or interest that remains unclaimed for two years (or if
then held by the Company or a Wholly Owned Subsidiary in trust for the payment
thereof), shall be discharged from such trust, and, thereafter, Securityholders
entitled to the 

 
                                                                              74

money must look to the Company for payment as general creditors; provided,
                                                                 -------- 
however, that the Trustee or such Paying Agent before being required to make 
- -------                                                             
any such repayment, may at the expense of the Company cause to be mailed to each
such Holder a notice that said moneys have not been so applied and that after a
date named therein any unclaimed balance of said moneys then remaining will be
returned to the Company.

          SECTION 8.05.  Indemnity for Government Obligations.  The Company
                         -------------------------------------             
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 8.06.  Reinstatement.  If the Trustee or Paying Agent is
                         --------------                                   
unable to apply any money or U.S. Government Obligations in accordance with this
Article 8 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 Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article 8 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 8;  provided, however, that, if the
                                               ---------  -------              
Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Company 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
                                  ----------

          SECTION 9.01.  Without Consent of Holders.  The Company and the
                         ---------------------------                     
Trustee may amend this Indenture or the Securities without notice to or consent
of any Securityholder:

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

          (2) to comply with Article 5;

 
                                                                              75

          (3) to provide for uncertificated Securities in addition to or in
     place of certificated Securities (provided that the uncertificated
     Securities are issued in registered form for purposes of Section 163(f) of
     the Code, or in a manner such that the uncertificated Securities are
     described in Section 163(f)(2)(B) of the Code);

          (4) to make any change in Article 10 that would limit or terminate the
     benefits available to any holder of Senior Debt of the Company (or
     Representatives therefor) under Article 10;

          (5) to secure the Securities;

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

          (7) to comply with any requirements of the SEC in connection with
     qualifying, or maintaining the qualification of, this Indenture under the
     TIA; or

          (8) to make any change that does not adversely affect the rights of
     any Securityholder in any material respect.

          An amendment under this Section may not make any change that adversely
affects the rights under Article 10 of any holder of Senior Debt then
outstanding unless the holders of such Senior Debt (or their Representative)
consent in writing to such change, it being understood that any amendment the
purpose of which is to permit the Incurrence of additional Debt shall not be
construed as impairing the rights of the holders of Senior Debt pursuant to such
subordination provisions.

          After an amendment under this Section becomes effective, the Company
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 under this Section.

          SECTION 9.02.  With Consent of Holders.  The Company and the Trustee
                         ------------------------                             
may amend this Indenture or the Securities without notice to any Securityholder
but with the written consent of the Holders of at least a majority in aggregate
principal amount of the Securities.  However, 

 
                                                                              76

without the consent of each Holder of an outstanding Security affected thereby
an amendment or waiver may not:

          (1) reduce the amount of Securities whose holders must consent to an
     amendment 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 Stated Maturity of any
     Security,

          (4) make any Security payable in money other than that stated in the
     Security,

          (5) impair the right of any holder of the Securities to receive
     payment of principal of and interest on such holder's Securities on or
     after the due dates therefor or to institute suit for the enforcement of
     any payment on or with respect to such holder's Securities,

          (6) release any security interest that may have been granted in favor
     of the holders of the Securities,

          (7) reduce the premium payable upon the redemption or repurchase of
     any Security, or change the time at which any Security may be redeemed, as
     described under Article 3,

          (8) reduce the premium payable upon a Change of Control or, at any
     time after a Change of Control or Asset Sale has occurred, change the time
     at which the Change of Control Offer or Prepayment Offer relating thereto
     must be made or at which the Securities must be repurchased pursuant to
     such Change of Control Offer, or

          (9) make any change to the subordination provisions of this Indenture
     that would adversely affect the holders of the Securities.

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

          An amendment under this Section may not make any change that adversely
affects the rights under Article 10 of any holder of Senior Debt then
outstanding unless the 

 
                                                                              77


holders of such Senior Debt (or their Representative) consent in writing to such
change, it being understood that any amendment the purpose of which is to permit
the Incurrence of additional Debt shall not be construed as impairing the rights
of the holders of Senior Debt pursuant to such subordination provisions.

          After an amendment under this Section becomes effective, the Company
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 under this Section.

          SECTION 9.03.  Compliance with Trust Indenture Act.  Every amendment
                         ------------------------------------                 
to this Indenture or the Securities shall comply with the TIA as then in effect.

          SECTION 9.04.  Revocation and Effect of Consents and Waivers.  A
                         ----------------------------------------------   
consent to an amendment or a 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 or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such
Holder's Security or portion of the Security if the Trustee receives the notice
of revocation before the date the amendment or waiver becomes effective. After
an amendment or waiver becomes effective, it shall form a part of this Indenture
for all purposes and shall bind every Securityholder. An amendment or waiver
becomes effective upon the execution of such amendment or waiver by the Trustee.

          The Company 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 9.05.  Notation on or Exchange of Securities.  If an amendment
                         --------------------------------------       
changes the terms of a Security, the 

 
                                                                              78

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 Company or the Trustee
so determines, the Company in exchange for the Security shall issue and the
Trustee shall authenticate a new Security that reflects the changed terms.
Failure to make the appropriate notation or to issue a new Security shall not
affect the validity of such amendment.

          SECTION 9.06.  Trustee To Sign Amendments.  The Trustee shall sign any
                         ---------------------------                            
amendment authorized pursuant to this Article 9 if such amendment 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 the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.01) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture.

          SECTION 9.07.  Payment for Consent.  Neither the Company nor any
                         --------------------                             
Affiliate of the Company 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.

          SECTION 10.01.  Agreement To Subordinate.  The Company agrees, and

each Securityholder by accepting a Security agrees, that the Securities are
subordinated obligations of the Company and that the Debt evidenced by the
Securities is subordinated in right of payment, to the extent and in the manner
provided in this Article 10, to the payment when due of all Senior Debt of the
Company and that the subordination is for the benefit of and enforceable by the
holders of such Senior Debt.  The Securities shall in all respects rank pari
                                                                        ----

only Senior Debt of the Company shall be senior to the Securities in

accordance with the provisions set forth herein. All provisions of this Article
10 shall be subject to Section 10.12.

          SECTION 10.02.  Liquidation, Dissolution, Bankruptcy.  Upon any 
                          -------------------------------------          
payment or distribution of the assets of the Company upon a total or partial
liquidation, dissolution or winding up of the Company or in a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to the
Company or its property:

          (1) holders of Senior Debt of the Company shall be entitled to receive
     payment in full in cash of such Senior Debt before Securityholders shall be
     entitled to receive any payment of principal of or interest on the
     Securities, except that Holders of Securities may receive and retain shares
     of stock and any debt securities that are subordinated to Senior Debt to at
     least the same extent as the Securities; and

          (2) until such Senior Debt is paid in full in cash, any distribution
     to which Securityholders would be entitled but for this Article 10 shall be
     made to holders of such Senior Debt as their interests may appear.

          SECTION 10.03.  Default on Senior Debt.  The Company may not pay the
                          -----------------------                             
principal of or interest on the Securities or make any deposit pursuant to
Section 8.01 and may not repurchase, redeem or otherwise retire any Securities
(collectively, "pay the Securities") if (a) any principal, premium or interest
in respect of any Senior Debt is not paid within any applicable grace period
(including at maturity) or (b) any other default on Senior Debt occurs and the
maturity of such Senior Debt is accelerated in accordance with its terms unless,
in either case, (i) the default has been cured or waived and any such
acceleration has been rescinded or (ii) such Senior Debt has been paid in full
in cash; provided, however, that the Company may pay the Securities without
         --------  -------                                                 
regard to the foregoing if the Company and the Trustee receive written notice
approving such payment from the Representative of each issue of Designated
Senior Debt.  During the continuance of any default (other than a default
described in clause (a) or (b) of the preceding sentence) with respect to any
Designated Senior Debt pursuant to which the maturity thereof may be accelerated
immediately without further notice (except notice required to effect the
acceleration) or the expiration of any applicable grace period, the Company may
not pay the Securities for a period (a "Payment Blockage

notice of such default from the Representative of the holders of such Designated
Senior Debt specifying an election to effect a Payment Blockage Period (a
"Payment Blockage Notice") and ending 179 days thereafter (unless such Payment
Blockage Period is earlier terminated (a) by written notice to the Trustee and
the Company from the Representative which gave such Payment Blockage Notice, (b)
because such default is no longer continuing or (c) because such Designated
Senior Debt has been repaid in full in cash). Unless the holders of such
Designated Senior Debt or the Representative of such holders have accelerated
the maturity of such Designated Senior Debt and not rescinded such acceleration,
the Company may (unless otherwise prohibited as described in the first sentence
of this paragraph) resume payments on the Securities after the end of such
Payment Blockage Period. Not more than one Payment Blockage Notice with respect
to all issues of Designated Senior Debt may be given in any consecutive 360-day
period, irrespective of the number of defaults with respect to one or more
issues of Designated Senior Debt during such period.

          SECTION 10.04.  Acceleration of Payment of Securities.  If payment of
                          --------------------------------------               
the Securities is accelerated because of an Event of Default, the Company or the
Trustee shall promptly notify the holders of the Designated Senior Debt (or
their Representatives) of the acceleration.  If payment of the Securities is
accelerated when any Designated Senior Debt is outstanding, the Company may not
pay the Securities until three Business Days after the Representatives of all
issues of Designated Senior Debt receive notice of such acceleration and,
thereafter, may pay the Securities only if this Indenture otherwise permits
payment at that time.

          SECTION 10.05.  When Distribution Must Be Paid Over.  If a
                          ------------------------------------      
distribution is made to Securityholders that because of this Article 10 should
not have been made to them, the Securityholders who receive the distribution
shall hold it in trust for holders of Senior Debt of the Company and pay it over
to them as their interests may appear.

          SECTION 10.06.  Subrogation.  After all Senior Debt of the Company is
                          ------------                                         
paid in full in cash and until the Securities are paid in full, Securityholders
shall be subrogated to the rights of holders of such Senior Debt to receive
distributions applicable to such Senior Debt.  A distribution made under this
Article 10 to holders of such Senior Debt which otherwise would have been made
to 

 
                                                                              81

Securityholders is not, as between the Company and Securityholders, a payment
by the Company on such Senior Debt.

          SECTION 10.07.  Relative Rights.  This Article 10 defines the relative
                          ----------------                                      
rights of Securityholders and holders of Senior Debt of the Company.  Nothing in
this Indenture shall:

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

          (2) prevent the Trustee or any Securityholder from exercising its
     available remedies upon a Default or an Event of Default, subject to the
     rights of holders of Senior Debt of the Company to receive distributions
     otherwise payable to Securityholders.

          SECTION 10.08.  Subordination May Not Be Impaired by Company.  No
                          ---------------------------------------------    
right of any holder of Senior Debt of the Company to enforce the subordination
of the Debt evidenced by the Securities shall be impaired by any act or failure
to act by the Company or by its failure to comply with this Indenture.

          SECTION 10.09.  Rights of Trustee and Paying Agent.  Notwithstanding
                          -----------------------------------                 
Section 10.03, the Trustee or Paying Agent may continue to make payments on the
Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Trust Officer receives notice
satisfactory to it that payments may not be made under this Article 10. The
Company, the Registrar or co-registrar, the Paying Agent, a Representative or a
holder of Senior Debt may give the notice; provided, however, that, if an issue
                                           --------  -------                   
of Senior Debt of the Company has a Representative, only the Representative may
give the notice.

          The Trustee in its individual or any other capacity may hold Senior
Debt of the Company with the same rights it would have if it were not Trustee.
The Registrar and co-registrar and the Paying Agent may do the same with like
rights.  The Trustee shall be entitled to all the rights set forth in this
Article 10 with respect to any Senior Debt of the Company which may at any time
be held by it, to the same extent as any other holder of such Senior 

 
                                                                              82

Debt; and nothing in Article 7 shall deprive the Trustee of any of its rights as
such holder. Nothing in this Article 10 shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 7.07.

          SECTION 10.10.  Distribution or Notice to Representative. Whenever a
                          -----------------------------------------            
distribution is to be made or a notice given to holders of Senior Debt of the
Company, the distribution may be made and the notice given to their
Representative (if any).

          SECTION 10.11.  Article 10 Not To Prevent Events of Default or Limit
                          ----------------------------------------------------
Right To Accelerate.  The failure to make a payment pursuant to the Securities
- --------------------                                                          
by reason of any provision in this Article 10 shall not be construed as
preventing the occurrence of a Default. Nothing in this Article 10 shall have
any effect on the right of the Securityholders or the Trustee to accelerate the
maturity of the Securities.

          SECTION 10.12.  Trust Moneys Not Subordinated. Notwithstanding
                          ------------------------------                
anything contained herein to the contrary, payments from money or the proceeds
of U.S. Government Obligations held in trust under Article 8 by the Trustee for
the payment of principal of and interest on the Securities shall not be
subordinated to the prior payment of any Senior Debt or subject to the
restrictions set forth in this Article 10, and none of the Securityholders shall
be obligated to pay over any such amount to the Company or any holder of Senior
Debt of the Company or any other creditor of the Company.

          SECTION 10.13.  Trustee Entitled To Rely.  Upon any payment or
                          -------------------------                     
distribution pursuant to this Article 10, the Trustee and the Securityholders
shall be entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 10.02
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representatives for the holders of Senior Debt
of the Company for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of such Senior Debt and
other Debt of the Company, the amount thereof or payable thereon, the amount or
amounts paid or distributed thereon and all other facts pertinent thereto or to
this Article 10. In the event that the Trustee determines, in good faith, that
evidence is required with respect to the right of any Person as a holder of
Senior Debt of the Company to participate in any payment 

 
                                                                              83

or distribution pursuant to this Article 10, the Trustee may request such Person
to furnish evidence to the reasonable satisfaction of the Trustee as to the
amount of such Senior Debt held by such Person, the extent to which such Person
is entitled to participate in such payment or distribution and other facts
pertinent to the rights of such Person under this Article 10, and, if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment. The provisions of Sections 7.01 and 7.02 shall be applicable to all
actions or omissions of actions by the Trustee pursuant to this Article 10.

          SECTION 10.14.  Trustee To Effectuate Subordination. Each
                          ------------------------------------      
Securityholder by accepting a Security authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination between the Securityholders and the holders of
Senior Debt of the Company as provided in this Article 10 and appoints the
Trustee as attorney-in-fact for any and all such purposes.

          SECTION 10.15.  Trustee Not Fiduciary for Holders of Senior Debt.  The
                          -------------------------------------------------     
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior
Debt and shall not be liable to any such holders if it shall mistakenly pay over
or distribute to Securityholders or the Company or any other Person, money or
assets to which any holders of Senior Debt of the Company shall be entitled by
virtue of this Article 10 or otherwise.

          SECTION 10.16.  Reliance by Holders of Senior Debt on Subordination
                          ---------------------------------------------------
Provisions.  Each Securityholder by accepting a Security acknowledges and agrees
- -----------                                                               
that the foregoing subordination provisions are, and are intended to be, an
inducement and a consideration to each holder of any Senior Debt of the Company,
whether such Senior Debt was created or acquired before or after the issuance of
the Securities, to acquire and continue to hold, or to continue to hold, such
Senior Debt and such holder of such Senior Debt shall be deemed conclusively to
have relied on such subordination provisions in acquiring and continuing to
hold, or in continuing to hold, such Senior Debt.

 
                                                                              84
