                                    PART II
 
                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Under Section 145 of the Delaware General Corporation Law ("DGCL"), a
corporation may indemnify its directors, officers, employees and agents and
its former directors, officers, employees and agents and those who serve, at
the corporation's request, in such capacities with another enterprise, against
expenses (including attorneys' fees), as well as judgments, fines and
settlements in nonderivative lawsuits, actually and reasonably incurred in
connection with the defense of any action, suit or proceeding in which they or
any of them were or are made parties or are threatened to be made parties by
reason of their serving or having served in such capacity. The DGCL provides,
however, that such person must have acted in good faith and in a manner such
person reasonably believed to be in (or not opposed to) the best interests of
the corporation and, in the case of a criminal action, such person must have
had no reasonable cause to believe his or her conduct was unlawful. In
addition, the DGCL does not permit indemnification in an action or suit by or
in the right of the corporation, where such person has been adjudged liable to
the corporation, unless, and only to the extent that, a court determines that
such person fairly and reasonably is entitled to indemnity for costs the court
deems proper in light of liability adjudication. Indemnity is mandatory to the
extent a claim, issue or matter has been successfully defended.
 
  The Restated Certificate contains provisions that provide that no director
of the Company shall be liable for breach of fiduciary duty as a director
except for (1) any breach of the directors' duty of loyalty to the Company or
its stockholders; (2) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of the law; (3) liability under
Section 174 of the DGCL; or (4) any transaction from which the director
derived an improper personal benefit. The Restated Certificate contains
provisions that further provide for the indemnification of directors and
officers to the fullest extent permitted by the DGCL. Under the Bylaws of the
Company, the Company is required to advance expenses incurred by an officer or
director in defending any such action if the director or officer undertakes to
repay such amount if it is determined that the director or officer is not
entitled to indemnification. In addition, the Company has entered into
indemnity agreements with each of its directors pursuant to which the Company
has agreed to indemnify the directors as permitted by the DGCL. The Company
has obtained directors and officers liability insurance against certain
liabilities, including liabilities under the Securities Act.

 (B) FINANCIAL STATEMENT SCHEDULES.
 
  The following financial statement schedule is filed herewith:
 
    Schedule II--Valuation and Qualifying Accounts
 
  Schedules not listed above have been omitted because they are inapplicable
or the information required to be set forth therein is provided in the
Consolidated Financial Statements of the Company or notes thereto.
 
ITEM 22. UNDERTAKINGS
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
  The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of this Registration Statement through
the date of responding to the request.
 
  The undersigned registrant hereby undertakes to supply by means of a post-
effective amendment all information concerning a transaction, and the company
being acquired involved therein, that was not the subject of and included in
this Registration Statement when it became effective.
 
  The undersigned registrant hereby undertakes that for purposes of
determining any liability under the Securities Act, the information omitted
from the form of prospectus filed as part of this Registration Statement in
reliance upon Rule 430A and contained in a form of prospectus filed by the
registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities
Act shall be deemed to be part of this Registration Statement as of the time
it was declared effective.
 
  The undersigned registrant hereby undertakes that for the purpose of
determining any liability under the Securities Act, each post-effective
amendment that contains a form of prospectus shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
 
  The undersigned registrant hereby undertakes to file, during any period in
which offers or sales are being made, a post-effective amendment to this
Registration Statement;
 
    (i) to include any prospectus required by Section 10(a)(3) of the
  Securities Act of 1933 (the "Securities Act");
 
    (ii) to reflect in the prospectus any facts or events arising after the
  effective date of this Registration Statement (or the most recent post-
  effective amendment hereof) which, individually or in the aggregate,
  represents a fundamental change in the information set forth in this
 
                                     II-11
<PAGE>
 
  Registration Statement. Notwithstanding the foregoing, any increase or
  decrease in volume of securities offered (if the total dollar value of
  securities offered would not exceed that which was registered) and any
  deviation from the low or high end of the estimated maximum offering range
  may be reflected in the form of prospectus filed with the Securities and
  Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the
  changes in volume and price represent no more than a 20% change in the
  maximum aggregate offering price set forth in the "Calculation of
  Registration Fee" table in this Registration Statement when it becomes
  effective; and
 
     (iii) to include any material information with respect to the plan of
  distribution not previously disclosed in this Registration Statement or any
  material change to such information in this Registration Statement.
 
  The undersigned registrant hereby undertakes to remove from registration by
means of a post-effective amendment any of the securities being registered
which remain unsold at the termination of the offering.

signing such instrument or instruments. Proof of execution of any such

4.02, 4.03 and 4.04 hereof) and the Trustee, on receipt of a Company Order
requesting such action, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when (a) either (i) all
outstanding Notes have been delivered to the Trustee for cancellation or (ii)
all such Notes not theretofore delivered to the Trustee for cancellation (A)
have become due and payable, (B) will become due and payable at their Stated
Maturity within one year or (C) are to be called for redemption within one year
under irrevocable arrangements satisfactory to the Trustee for the giving of
notice of redemption by the Trustee in the name, and at the expense, of the
Company, and the Company, in the case of (A), (B) or (C) above, has irrevocably
deposited or caused to be deposited with the Trustee as trust funds in trust for
the purpose an amount sufficient to pay and discharge the entire indebtedness on
such Notes, for principal (and premium, if any) and interest to the date of such

Stated Maturity or Redemption Date, as the case may be, together with
irrevocable instructions from the Company in form and substance satisfactory to
the Trustee directing the Trustee to apply such funds to the payment thereof;
(b) the Company has paid or caused to be paid all other sums payable hereunder
by the

                                      25
<PAGE>
 
Company; and (c) the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of this
Indenture have been complied with.  Notwithstanding the satisfaction and

the Company to the Trustee under Section 7.07 hereof, and, if money shall have
been deposited with the Trustee in trust for the Holders pursuant to this
Section 1.06, the obligations of the Trustee under this Section 1.06 and Section
4.03 hereof shall survive.

    All money deposited with the Trustee pursuant to this Section 1.06 shall be
held in trust and applied by it, in accordance with the provisions of the Notes
and this Indenture, to the payment, either directly or through any Paying Agent,
to the Persons entitled thereto, of the principal (and premium, if any) and
interest for the payment of which such money has been deposited with the
Trustee.  If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with this Section 1.06 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 Notes shall
be revived and reinstated as though no deposit had occurred pursuant to this
Section 1.06 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
Section 1.06; provided that, if the Company has made any payment of interest on
or principal of any Notes because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the cash or U.S. Government Obligations held by the
Trustee or Paying Agent.

Common Stock in a Strategic Equity Investment on or before July 15, 2000, in
which case the Company may, at its option, use all or a portion of any such net
proceeds to redeem Notes in a principal amount of up to an aggregate amount
equal to 33 1/3% of the original principal amount of the Notes, provided,
however, that Notes in an amount equal to at least 66 2/3% of the original
principal amount of the Notes remain outstanding after such redemption.  Such
redemption must occur on a Redemption Date within 90 days of any such sale and
upon not less than 30 nor more than 60 days' notice by mail to each Holder of

Change of Control (as defined in the Indenture) occurs, (ii) the CCI Transaction

                                      32
<PAGE>
 
not consummated by the Termination Date (as defined in the Indenture) or is
terminated prior to such date, or (iii) certain Excess Proceeds are available to
the Company as a result of any Asset Sale, the Company shall be required to make
a Change of Control Offer, a CCI Transaction Put Option Offer or an Asset Sale
Offer, as the case may be, for all or a specified portion of the Notes.

          [If not a Global Security insert -- In the event of redemption or
purchase pursuant to an Asset Sale Offer of this Note in part only, a new Note
or Notes of like tenor for the unredeemed or unpurchased portion hereof will be
issued in the name of the Holder hereof upon the cancellation hereof.]

          [If a Global Security insert -- In the event of a deposit or
withdrawal of an interest in this Note (including upon an exchange, transfer,
redemption or repurchase of this Note in part only) effected in accordance with
the Applicable Procedures, the Note Registrar, upon receipt of notice of such
event from the Depositary's custodian for this Note, shall make an adjustment on
its records to reflect an increase or decrease of the outstanding principal
amount of this Note resulting from such deposit or withdrawal, as the case may
be.]

          If an Event of Default shall occur and be continuing, the principal of
all the Notes may be declared due and payable in the manner and with the effect
provided in the Indenture.

          The Indenture contains provisions for defeasance at any time of (i)
the entire indebtedness of this Note, or (ii) certain restrictive covenants and
Events of Default with respect to this Note, in each case upon compliance with
certain conditions set forth therein.

          Unless the context otherwise requires, the Original Notes (as defined
in the Indenture) and the Exchange Notes (as defined in the Indenture) shall
constitute one series for all purposes under the Indenture, including without
limitation, amendments, waivers, redemptions, Change of Control Offers, CCI
Transaction Put Option Offers and Asset Sale Offers.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Notes under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Notes at the time outstanding.
The Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Notes at the time outstanding,
on behalf of the Holders of all the Notes, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences.  Any such consent or waiver by the Holder of
this Note shall be conclusive and binding upon such Holder and upon all future
Holders of this Note and of any Note issued upon the registration of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Note.

          No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Note at the times, place and rate, and in the coin or currency,
herein prescribed.

therein set forth, the transfer of this Note is registrable in the Note
Register, upon surrender of this Note for registration of transfer at the office
or agency of the Company in the Borough of Manhattan, The City of New York, New
York, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Note Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Notes, of authorized denominations and like tenor and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

          The Notes are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, Notes are
exchangeable for a like tenor and aggregate principal amount of Notes of a
different authorized denomination, as requested by the Holder surrendering the
same.

          No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

          Prior to due presentment of this Note for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Note is registered as the owner hereof for all
purposes, whether or not this Note be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

of twelve 30-day months; provided, however, that Special Interest shall be
computed on the basis of a 365-or 366-day year, as the case may be, and the

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

     This is one of the Notes referred to in the within-mentioned Indenture.

                                         Authorized Signatory

     SECTION 2.05.   Execution and Authentication.  The aggregate principal
                     ----------------------------                          
amount of Notes outstanding at any time shall not exceed $225,000,000.  The
Notes shall be executed on behalf of the Company by its Chief Executive Officer,
its President or any Executive Vice President and shall be attested by the
Company's Secretary or one of its Assistant Secretaries, in each case by manual
or facsimile signature.

     The Notes shall be authenticated by manual signature of an authorized
officer of the Trustee and shall not be valid for any purpose unless so
authenticated.

     In case any officer of the Company whose signature shall have been placed
upon any of the Notes shall cease to be such officer of the Company before
authentication of such Notes by the Trustee and the issuance and delivery
thereof, such Notes may, nevertheless, be authenticated by the Trustee and
issued and delivered with the same force and effect as though such Person had
not ceased to be such officer of the Company.

     Notwithstanding any other provision hereof, the Trustee shall authenticate
and deliver Notes only upon receipt by the Trustee of an Officers' Certificate
complying with Section 10.04 hereof with respect to satisfaction of all
conditions precedent contained in this Indenture to authentication and delivery
of such Notes.

     Upon compliance by the Company with the provisions of the previous
paragraph, the Trustee shall, upon receipt of a Company Order requesting such
action, authenticate Notes for original issuance in an aggregate principal
amount not to exceed $225,000,000.  Such Company Order shall specify the amount
of Notes to be authenticated and the date on which the Notes are to be
authenticated and shall further provide instructions concerning registration,
amounts for each Holder and delivery.

     A Note shall not be valid or entitled to any benefit under this Indenture
or obligatory for any purpose unless executed by the Company and authenticated
by the manual signature of the Trustee as provided herein.  The signature of an
authorized officer of the Trustee shall be conclusive evidence, and the only
evidence, that such Note has been authenticated and delivered under this
Indenture.

                                      38
<PAGE>
 
     The Trustee may appoint an authenticating agent reasonably acceptable to
the Company to authenticate the Notes.  Unless limited by the terms of such
appointment, an authenticating agent may authenticate Notes whenever the Trustee
may do so.   Each reference in this Indenture to authentication by the Trustee
includes authentication by such agent.   Any authenticating agent of the Trustee
shall have the same rights hereunder as any Registrar or Paying Agent.  The
Trustee shall not be liable for any failure to act of the authenticating agent
in performing any duty either required herein or authorized herein to be
performed by such person in accordance with the Indenture.

      SECTION 2.06.   Note Registrar and Paying Agent.  The Company shall
                      -------------------------------                    
maintain, pursuant to Section 4.02 hereof, an office or agency where the Notes
may be presented for registration of transfer or for exchange.  The Company
shall cause to be kept at such office a register (the register maintained in
such office being herein sometimes referred to as the "Note Register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
provide for the registration of Notes and of transfers of Notes entitled to be
registered or transferred as provided herein.  The Trustee, at its Corporate
Trust Office, is initially appointed "Note Registrar" for the purpose of
registering Notes and transfers of Notes as herein provided.  The Company may,
upon written notice to the Trustee, change the designation of the Trustee as
Note Registrar and appoint another Person to act as Note Registrar for purposes
of this Indenture.  If any Person other than the Trustee acts as Note Registrar,
the Trustee shall have the right at any time, upon reasonable notice, to inspect
or examine the Note Register and to make such inquiries of the Note Registrar as
the Trustee shall in its discretion deem necessary or desirable in performing
its duties hereunder.

     The Company shall enter into an appropriate agency agreement with any
Person designated by the Company as Note Registrar or Paying Agent that is not a
party to this Indenture, which agreement shall incorporate the provisions of the
Trust Indenture Act and shall implement the provisions of this Indenture that
relate to such Note Registrar or Paying Agent.  Prior to the designation of any
such Person, the Company shall, by written notice (which notice shall include
the name and address of such Person), inform the Trustee of such designation.
If the Company fails to maintain a Note Registrar or Paying Agent, the Trustee
shall act as such.

     Upon surrender for registration of transfer of any Note at an office or
agency of the Company designated for such purpose, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Initial Notes or Exchange Notes, as
the case may be, of any authorized denomination or denominations, of like tenor
and aggregate principal amount, all as requested by the transferor.

     Every Note presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company, the Trustee or the Note
Registrar) be duly endorsed, or be accompanied by a duly executed instrument of
transfer in form satisfactory to the Company,

liability for the money delivered to the Trustee.

     SECTION 2.08.  Registration, Registration of Transfer and Exchange.
                     --------------------------------------------------- 

     (a) At the option of the Holder, and subject to the other provisions of

of the Notes to be exchanged at such office or agency.  Whenever any Notes are
so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Notes which the Holder making the exchange is
entitled to receive.

shall be the valid obligations of the Company, evidencing the same debt, and

exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Note Registrar duly executed, by the Holder thereof or his
attorney duly authorized in writing.

exchange any Note during a period beginning at the opening of business 15 days
before the day of the mailing of a notice of redemption of Notes selected for
redemption under Section 3.03 and ending at the close of business on the day of

     at any time to transfer such interest to a Person who wishes to acquire the
     same in the form of a beneficial interest in the Regulation S Global
     Security, such transfer may be effected only in accordance with the
     provisions of this Clause (b)(i) and Clause (b)(vii) below and subject to

     account and (B) a Regulation S Certificate, satisfactory to the Trustee and
     duly executed by the owner of such beneficial interest in the Restricted

     (iv)   Regulation S Non-Global Security to Restricted Global Security or
            ---------------------------------------------- ------------------

- ----------------------------                                               
Holder of a Regulation S Note (other than a Global Security) wishes at any time

                                      42
<PAGE>
 
(b)(iv) and Clause (b)(vii) below and subject to the Applicable Procedures.
Upon receipt by the Trustee, as Note Registrar, of (A) such Regulation S Note as

Global Security may be transferred, in whole or in part, to a Person who takes
delivery in the form of another Note that is not a Global Security as provided
in Section 2.08(a), provided that, if the Note to be transferred in whole or in
part is a Restricted Note, or is a Regulation S Note and the transfer is to

     (vi)  Exchanges between Global Security and Non-Global Security.  A
           ---------------------------------------------------------    
beneficial interest in a Global Security may be exchanged for a Note that is not

interest is a beneficial interest in the Restricted Global Security, or if such
interest is a beneficial interest in the Regulation S Global Security and such
exchange is to occur during the Restricted Period, then such interest shall be
exchanged for a Restricted Note (subject in each case to Section 2.08(c)).  A

                      ----------------------------------------------- ---------
     or Cedel during Restricted Period.  The Company shall use its best efforts

     to cause the Depositary to ensure that, until the expiration of the
     Restricted Period, beneficial interests in the Regulation S Global Security
     may be held only in or through accounts maintained at the Depositary by
     Euroclear or Cedel (or by Agent Members acting for the account thereof),
     and no person shall be entitled to effect any transfer or exchange that
     would result in any such interest being held otherwise than in or through
     such an account; provided that this Clause (b)(vii) shall not prohibit any
     transfer or exchange of such an interest in accordance with Clause (b)(ii)
     or (vi) above.

     (c) Securities Act Legends.  Rule 144A Notes, Other Notes and their
         ----------------------                                         
respective Successor Notes shall bear a Restricted Note Legend, and the
Regulation S Notes and their Successor Notes shall bear a Regulation S Legend,
subject to the following:

               (i)   subject to the following Clauses of this Section 2.08(c), a
     Note or any portion thereof which is exchanged, upon transfer or otherwise,
     for a Global Security or any portion thereof shall bear the Securities Act
     Legend borne by such Global Security while represented thereby;

               (ii)  subject to the following Clauses of this Section 2.08(c), a
     new Note which is not a Global Security and is issued in exchange for
     another Note (including a Global Security) or any portion thereof, upon
     transfer or otherwise, shall bear the Securities Act Legend borne by such
     other Note, provided that, if such new Note is required pursuant to Section
     2.08(b)(v) or (vi) to be issued in the form of a Restricted Note, it shall
     bear a Restricted Note Legend and, if such new Note is so required to be
     issued in the form of a Regulation S Note, it shall bear a Regulation S
     Legend;

               (iii)  Registered Notes shall not bear a Securities Act Legend;

               (iv)   at any time after the Notes may be freely transferred
     without registration under the Securities Act or without being subject to
     transfer restrictions pursuant to the Securities Act, a new Note which does
     not bear a Securities Act Legend may be issued in exchange for or in lieu
     of a Note (other than a Global Security) or any portion thereof which bears
     such a legend if the Trustee has received an Unrestricted Note Certificate,
     satisfactory to the Trustee and duly executed by the Holder of such
     legended Note or his attorney duly authorized in writing, and after such
     date and receipt of such certificate, the Trustee shall authenticate and
     deliver such a new Note in exchange for or in lieu of such other Note as
     provided in this Article II;

               (v)    a new Note which does not bear a Securities Act Legend may
     be issued in exchange for or in lieu of a Note (other than a Global
     Security) or any portion thereof which bears such a legend if, in the
     Company's judgment, placing such a legend upon such new Note is not
     necessary to ensure compliance with the registration requirements of the
     Securities Act, and the Trustee, at the direction of the

                                      44
<PAGE>
 
      Company, shall authenticate and deliver such a new Note as provided in
      this Article II; and

               (vi)  notwithstanding the foregoing provisions of this Section
     2.08(c), a Successor Note of a Note that does not bear a particular form of
     Securities Act Legend shall not bear such form of legend unless the Company
     has reasonable cause to believe that such Successor Note is a "restricted
     security" within the meaning of Rule 144, in which case the Trustee, at the
     direction of the Company, shall authenticate and deliver a new Note bearing
     a Restricted Note Legend in exchange for such Successor Note as provided in
     this Article II.

     (d) The provisions of Clauses (1), (2), (3), (4) and (5) below shall apply
only to Global Securities:

         (1) Each Global Security authenticated under this Indenture shall be
     registered in the name of the Depositary or a nominee thereof and delivered
     to the Depositary or a nominee thereof or custodian therefor, and each such
     Global Security shall constitute a single Note for all purposes of this
     Indenture.

         (2) Notwithstanding any other provision in this Indenture, no Global
     Security may be exchanged in whole or in part for Notes registered, and no
     transfer of a Global Security in whole or in part may be registered, in the
     name of any Person other than the Depositary or a nominee thereof unless
     (i) the Depositary notifies the Company that it is unwilling or unable to
     continue as a depositary for such Global Security or if at any time the
     Depositary ceases to be a clearing agency registered under the Exchange
     Act, and a successor depositary is not appointed by the Company within 90
     days, (ii) the Company executes and delivers to the Trustee a notice that
     such Global Security shall be so transferable, registrable and
     exchangeable, and such transfer shall be registrable or (iii) there shall
     have occurred and be continuing an Event of Default with respect to the
     Notes represented by such Global Security.

         (3) If any Global Security is to be exchanged for other Notes or
     cancelled in whole, it shall be surrendered by or on behalf of the
     Depositary or its nominee to the Trustee, as Note Registrar, for exchange
     or cancellation as provided in this Article II. If any Global Security is
     to be exchanged for other Notes or cancelled in part, or if another Note is
     to be exchanged in whole or in part for a beneficial interest in any Global
     Security, then either (i) such Global Security shall be so surrendered for
     exchange or cancellation as provided in this Article II or (ii) the
     principal amount thereof shall be reduced or increased by an amount equal
     to the portion thereof to be so exchanged or cancelled, or equal to the
     principal amount of such other Note to be so exchanged for a beneficial
     interest therein, as the case may be, by means of an appropriate adjustment
     made on the records of the Trustee, as Note Registrar, whereupon the
     Trustee, in accordance with the Applicable Procedures, shall instruct the
     Depositary or its authorized representative to make a corresponding
     adjustment to

                                      45
<PAGE>
 
     its records. Upon any such surrender or adjustment of a Global Security,
     the Trustee shall, subject to Section 2.08(d)(2) and as otherwise provided
     in this Article II, authenticate and deliver any Notes issuable in exchange
     for such Global Security (or any portion thereof) to or upon the order of,
     and registered in such names as may be directed by, the Depositary or its
     authorized representative. Upon the request of the Trustee in connection
     with the occurrence of any of the events specified in the preceding
     paragraph, the Company shall promptly make available to the Trustee a
     reasonable supply of Notes that are not in the form of Global Securities.
     The Trustee shall be entitled to rely upon any order, direction or request
     of the Depositary or its authorized representative which is given or made
     pursuant to this Article II if such order, direction or request is given or
     made in accordance with the Applicable Procedures.

         (4) Every Note authenticated and delivered upon registration of
     transfer of, or in exchange for or in lieu of, a Global Security or any
     portion thereof, whether pursuant to this Section, Section 2.05, 2.09,
     3.06, 4.07, 4.08, 4.09 or 9.06 or otherwise, shall be authenticated and
     delivered in the form of, and shall be, a Global Security, unless such Note
     is registered in the name of a Person other than the Depositary or a
     nominee thereof.

         (5) None of the Company, the Trustee, any agent of the Trustee, any
     Paying Agent or the Note Registrar will have any responsibility or
     liability for any aspect of the Depository's records (or the records of the
     participant of such Depository) relating to or payments made on account of
     beneficial ownership interests of a Global Security or for maintaining,
     supervising or reviewing any records of the Depository relating to such
     beneficial ownership interests.

     SECTION 2.09.  Replacement Notes.  If any mutilated Note is surrendered to
                    -----------------                                          
the Trustee, the Company shall execute and upon its written request the Trustee
shall authenticate and deliver, in exchange for any such mutilated Note, a new
Note containing identical provisions and of like principal amount, bearing a
number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Note and (ii) such
security or indemnity as may be required by them to save either of them and any
agent of each of them harmless, then, in the absence of notice to the Company or
the Trustee that such Note has been acquired by a bona fide purchaser, the
Company shall execute and upon its request the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Note, a new Note
containing identical provisions and of like principal amount, bearing a number
not contemporaneously outstanding.

                                      46
<PAGE>
 
     In case any such mutilated, destroyed, lost or stolen Note has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Note, pay such Note.

     Upon the issuance of any new Note under this Section 2.09, the Company may
require the payment by the Holder of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

     Every new Note issued pursuant to this Section 2.09 in lieu of any
destroyed, lost or stolen Note shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Note shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all
other Notes duly issued hereunder.

     The provisions of this Section 2.09 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

     SECTION 2.10.  Outstanding Notes.  Notes outstanding at any time are all
                    -----------------                                        
Notes authenticated by the Trustee except for those canceled by it, those
delivered to it for cancellation and those described in this Section 2.10 as not
outstanding.  A Note does not cease to be outstanding because the Company or an
Affiliate of the Company holds such Note.

     If a Note is replaced pursuant to Section 2.09 hereof, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that such replaced Note 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, premium, if any, and interest payable on that date with respect to
the Notes (or portions thereof) to be redeemed or maturing, as the case may be,
then on and after that date such Notes (or such portions thereof) shall cease to
be outstanding and interest on them shall cease to accrue.

     In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent or any amendment,
modification or other change to this Indenture, Notes held or beneficially owned
by the Company or a Restricted Subsidiary of the Company or by an Affiliate of
the Company or a Restricted Subsidiary of the Company or by agents of any of the
foregoing shall be disregarded, except that for the purposes of determining
whether the Trustee shall be protected in relying on any such direction, waiver
or consent or any amendment, modification or other change to this Indenture,
only Notes which a Trust Officer knows are so owned shall be so disregarded.
Notes so owned which have been pledged in good faith shall not be disregarded if
the

                                      47
<PAGE>
 
pledgee establishes to the satisfaction of the Trustee such pledgee's right so
to act with respect to the Notes and that the pledgee is not the Company or an
Affiliate of the Company or any of their agents.

     SECTION 2.11.  Temporary Notes.  Pending the preparation of definitive
                    ---------------                                        
Notes, the Company may execute, and the Trustee shall authenticate, temporary
notes ("Temporary Notes") which are printed, lithographed, or otherwise
produced, substantially of the tenor of the definitive Notes in lieu of which
they are issued and with such appropriate insertions, omissions, substitutions
and other variations.

     If Temporary Notes are issued, the Company shall cause definitive Notes to
be prepared without unreasonable delay.  After the preparation of definitive
Notes, the Temporary Notes shall be exchangeable for definitive Notes upon
surrender of the Temporary Notes to the Trustee, without charge to the Holder.
Until so exchanged, Temporary Notes will evidence the same debt and will be
entitled to the same benefits under this Indenture as the definitive Notes in
lieu of which they have been issued.

     SECTION 2.12.  Cancellation.  The Company at any time may deliver Notes to
                    ------------                                               
the Trustee for cancellation.  The Note Registrar and the Paying Agent shall
forward to the Trustee any Notes surrendered to them for registration of
transfer, exchange, purchase or payment.  The Trustee shall cancel all Notes
surrendered for registration of transfer, exchange, purchase, payment or
cancellation and shall destroy such canceled Notes unless the Company shall by
Company Order otherwise direct. The Company may not issue new Notes to replace
Notes that have been delivered to the Trustee for cancellation.

     SECTION 2.13.  Payment of Interest; Interest Rights Preserved.  Interest
                    ----------------------------------------------           
on any Note which is payable, and is punctually paid or duly provided for, on
any Interest Payment Date shall be paid to the Person in whose name such Note is
registered at the close of business on the Regular Record Date for such interest
payment, which shall be the December 30 or June 30 (whether or not a Business
Day) immediately preceding such Interest Payment Date.

     Any interest on any Note which is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date (herein called "Defaulted
Interest") shall forthwith cease to be payable to the registered Holder on the
relevant Regular Record Date, and, except as hereinafter provided, such
Defaulted Interest, and any interest payable on such Defaulted Interest, may be
paid by the Company, at its election, as provided in clause (a) or (b) below:

        (a) The Company may elect to make payment of any Defaulted Interest, and
     any interest payable on such Defaulted Interest, to the Persons in whose
     names the Notes are registered at the close of business on a Special Record
     Date for the payment of such Defaulted Interest, which shall be fixed in
     the following manner. The Company shall notify the Trustee in writing of
     the amount of Defaulted Interest

                                      48
<PAGE>
 
     proposed to be paid on the Notes and the date of the proposed payment, and
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as provided in this Clause. Thereupon the Trustee
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which shall be not more than 15 calendar days and not less than 10 calendar
     days prior to the date of the proposed payment and not less than 10
     calendar days after the receipt by a Trust Officer of the Trustee of the
     notice of the proposed payment. The Trustee shall promptly notify the
     Company of such Special Record Date and, in the name and at the expense of
     the Company, shall cause notice of the proposed payment of such Defaulted
     Interest and the Special Record Date therefor to be sent, first class mail,
     postage prepaid, to each Holder at such Holder's address as it appears in
     the Note Register, not less than 10 calendar days prior to such Special
     Record Date. Notice of the proposed payment of such Defaulted Interest and
     the Special Record Date therefor having been mailed as aforesaid, such
     Defaulted Interest shall be paid to the Persons in whose names the Notes
     are registered at the close of business on such Special Record Date and
     shall no longer be payable pursuant to the following clause (b).

        (b) The Company may make payment of any Defaulted Interest, and any
     interest payable on such Defaulted Interest, on the Notes in any other
     lawful manner not inconsistent with the requirements of any securities
     exchange on which the Notes may be listed, and upon such notice as may be
     required by such exchange, if, after notice given by the Company to the
     Trustee of the proposed payment pursuant to this clause, such manner of
     payment shall be deemed practicable by the Trustee.

     Subject to the foregoing provisions of this Section 2.13, each Note
delivered under this Indenture upon registration of transfer of, or in exchange
for, or in lieu of, any other Note, shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Note.

     SECTION 2.14.  Authorized Denominations.  The Notes shall be issuable in
                    ------------------------                                 
minimum denominations of $1,000 and any integral multiple thereof.

     SECTION 2.15.  Computation of Interest.  Interest on the Notes shall be
                    -----------------------                                 
computed on the basis of a 360-day year of twelve 30-day months; provided that
Special Interest shall be computed on the basis of a 365- or 366-day year, as
the case may be, and the number of days actually elapsed from the date Special
Interest commences to accrue to but not including the date on which Special
Interest ceases to accrue.

     SECTION 2.16.  Persons Deemed Owners.  Prior to the due presentation for
                    ---------------------                                    
registration of transfer of any Note, the Company, the Trustee, the Paying
Agent, the Note

                                      49
<PAGE>
 
Registrar or any co-registrar may deem and treat the person in whose name Note
is registered as the absolute owner of such Note for the purpose of receiving
payment of principal of, premium, if any, and interest on such Note and for all
other purposes whatsoever, whether or not such Note is overdue, and none of the
Company, the Trustee, the Paying Agent, the Note Registrar or any co-Registrar
shall be affected by notice to the contrary.

     SECTION 2.17.  CUSIP Numbers.  The Company, in issuing the Notes, may use
                    -------------                                             
"CUSIP" and "ISIN" numbers for each series of Notes and, if so, the Trustee
shall use the relevant CUSIP and ISIN numbers in any notices to Holders as a
convenience to such Holders; provided that any such notice may state that no
representation is made as to the correctness or accuracy of the CUSIP and ISIN
numbers printed in the notice or on the Notes and that reliance may be placed
only on the other identification numbers printed on the Notes.  The Company
shall promptly notify the Trustee of any change in any CUSIP or "ISIN" numbers
used.

     SECTION 2.18.  Holder 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 Holders and shall otherwise comply with Trust Indenture
Act (S) 312(a).  If the Trustee is not the Note Registrar, the Company shall
furnish to the Trustee as of each Regular Record 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 Holders,
including the aggregate principal amount of Notes held by each Holder.

                                 ARTICLE III.

                                  REDEMPTION

     SECTION 3.01.  Notice to Trustee.  If the Company elects to redeem Notes
                    -----------------                                        
pursuant to paragraph two or three of the reverse side of the Notes, it shall
notify the Trustee in writing of the Redemption Date and the principal amount of
Notes to be redeemed.  The Company shall give each such notice to the Trustee at
least 60 calendar days prior to the Redemption Date unless the Trustee consents
in writing to a shorter period.  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 any conditions to such redemption set
forth herein and in the Notes.

     SECTION 3.02.  Selection of Notes to be Redeemed.  If less than all the
                    ---------------------------------                       
Notes are to be redeemed at any time, the Trustee shall select the Notes to be
redeemed by lot, on a pro rata or other basis as it shall deem fair and
appropriate; provided that the Trustee may select for redemption in part only
Notes in denominations larger than $1,000.  In selecting Notes to be redeemed
pursuant to this Section 3.02, the Trustee shall make such adjustments,
reallocations and eliminations as it shall deem proper so that the principal
amount of each Note to be redeemed shall be $1,000 or an integral multiple
thereof, by increasing,

                                      50
<PAGE>
 
decreasing or eliminating any amount less than $1,000 which would be allocable
to any Holder.  If the Notes to be redeemed are Certificated Notes, the
Certificated Notes to be redeemed shall be selected by the Trustee by prorating,
as nearly as may be, the principal amount of Certificated Notes to be redeemed
among the Holders of Certificated Notes registered in their respective names.
The Trustee in its discretion may determine the particular Notes (if there are
more than one) registered in the name of any Holder which are to be redeemed, in
whole or in part. Provisions of this Indenture that apply to Notes called for
redemption also apply to portions of Notes called for redemption.  The Trustee
shall notify the Company promptly of the Notes or portions of Notes to be
redeemed.

     SECTION 3.03.  Notice of Redemption.  At least 30 calendar days but not
                    --------------------                                    
more than 60 calendar days before a Redemption Date, the Company shall send a
notice of redemption, first class mail, postage prepaid, to Holders of Notes to
be redeemed at the addresses of such Holders as they appear in the Note
Register.

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

        (a)  the Redemption Date;

        (b) the Redemption Price (and shall specify the portion of such
     Redemption Price that constitutes the amount of accrued and unpaid interest
     to be paid, if any);

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

        (d) that the Notes called for redemption must be surrendered to the
     Paying Agent to collect the Redemption Price;

        (e) if any Note is being redeemed in part, the portion of the principal
     amount of such Note to be redeemed and that, after the Redemption Date, a
     new Note or Notes in principal amount equal to the unredeemed portion will
     be issued;

        (f) if fewer than all the outstanding Notes are to be redeemed, the
     identification and principal amounts of the particular Notes to be
     redeemed;

        (g) that, unless the Company defaults in making the redemption payment,
     interest on the Notes (or portions thereof) called for redemption shall
     cease and such Notes (or portions thereof) shall cease to accrue interest
     on and after the Redemption Date;

        (h) the paragraph of the Notes pursuant to which the Notes are being
     called for redemption; and

        (i) any other information necessary to enable Holders to comply with the
     notice of redemption.

                                      51
<PAGE>
 
     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 3.03 in
a timely manner.

     SECTION 3.04.  Effect of Notice of Redemption.  Once notice of redemption
                    ------------------------------                            
is mailed, Notes called for redemption shall become due and payable on the
Redemption Date and at the Redemption Price stated in such notice.  Upon
surrender to the Paying Agent, such Notes shall be paid at the Redemption Price
stated in such notice.  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.  On or prior to 10:00 a.m.,
                    ---------------------------                             
New York City time, on each Redemption Date, the Company shall deposit with the
Paying Agent (or, if the Company, one of its Subsidiaries or any of their
Affiliates is the Paying Agent, the Paying Agent shall segregate and hold in
trust for the benefit of the Holders) money, in federal or other immediately
available funds, sufficient to pay the Redemption Price on all Notes to be
redeemed on that date other than Notes or portions of Notes called for
redemption on such date which have been delivered by the Company to the Trustee
for cancellation.

     So long as the Company complies with the preceding paragraph and the other
provisions of this Article III, interest on the Notes to be redeemed on the
applicable Redemption Date shall cease to accrue from and after such date and
such Notes or portions thereof shall be deemed not to be entitled to any benefit
under this Indenture except to receive payment of the Redemption Price on the
Redemption Date.  If any Note called for redemption shall not be so paid upon
surrender for redemption, then, from the Redemption Date until such principal is
paid, interest shall be paid on the unpaid principal and, to the extent
permitted by law, on any accrued but unpaid interest thereon, in each case at
the rate prescribed therefor by such Notes.

     SECTION 3.06.  Notes Redeemed in Part.  Upon surrender and cancellation of
                    ----------------------                                     
a Note that is redeemed in part, the Company shall issue and the Trustee shall
authenticate and deliver to the surrendering Holder (at the Company's expense) a
new Note equal in principal amount to the unredeemed portion of the Note
surrendered and canceled; provided that each such Note shall be in a principal
amount of $1,000 or an integral multiple thereof.


                                  ARTICLE IV.

                                   COVENANTS

     SECTION 4.01.  Payment of Notes.  The Company shall promptly pay the
                    ----------------                                     
principal of, premium, if any, and interest on, the Notes on the dates and in
the manner provided in the Notes and in this Indenture.  Principal, premium and
interest shall be considered paid on

                                      52
<PAGE>
 
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, premium
and interest then due.

     To the extent lawful, the Company shall pay interest on (i) any overdue
principal of (and premium, if any, on) the Notes, at the interest rate borne on
the Notes, plus 1% per annum, and (ii) Defaulted Interest (without regard to any
applicable grace period), at the same rate.  The Company's obligation pursuant
to the previous sentence shall apply whether such overdue amount is due at its
Stated Maturity, as a result of the Company's obligations pursuant to Section
3.05, Section 4.07, Section 4.08 or Section 4.09 hereof, or otherwise.

     SECTION 4.02.  Maintenance of Office or Agency.  The Company shall
                    -------------------------------                    
maintain in the Borough of Manhattan, The City of New York, an office or agency
where Notes may be presented or surrendered for payment, where Notes may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Company in respect of the Notes and this Indenture may be
served.  The Company shall give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency.  If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee its agent to
receive all presentations, surrenders, notices and demands.

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

     SECTION 4.03.  Money for the Note Payments to be Held in Trust.  If the
                    -----------------------------------------------         
Company, any Subsidiary of the Company or any of their respective Affiliates
shall at any time act as Paying Agent with respect to the Notes, such Paying
Agent shall, on or before each due date of the principal of (and premium, if
any) or interest on any of the Notes, segregate and hold in trust for the
benefit of the Persons entitled thereto money sufficient to pay the principal
(and premium, if any) or interest so becoming due until such money shall be paid
to such Persons or otherwise disposed of as herein provided, and shall promptly
notify the Trustee of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents with respect to
the Notes, it shall, prior to or on each due date of the principal of (and
premium, if any) or interest on any of the Notes, deposit with a Paying Agent a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such

                                      53
<PAGE>
 
Paying Agent is the Trustee) the Paying Agent shall promptly notify the Trustee
of the Company's action or failure so to act.

     SECTION 4.04.  Corporate Existence.  Subject to the provisions of Article
                    -------------------                                       
IV and Article V hereof, the Company shall do or cause to be done all things
necessary to preserve and keep in full force and effect the corporate existence,
rights (charter and statutory) and franchises of the Company and each of its
Restricted Subsidiaries; provided that the Company and any such Restricted
Subsidiary shall not be required to preserve the corporate existence of any such
Restricted Subsidiary or any such right or franchise if the Board of Directors
shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company and provided further that any Restricted
Subsidiary may consolidate with, merge into, or sell, convey, lease or otherwise
dispose of all of its property and assets to the Company or any wholly owned
Restricted Subsidiary.

     SECTION 4.05.  Maintenance of Property.  The Company shall cause all
                    -----------------------                              
Property used or useful in the conduct of its business or the business of any of
its Restricted Subsidiaries and material to the Company and its Restricted
Subsidiaries taken as a whole to be maintained and kept in good condition,
repair and working order and supplied with all necessary equipment and shall
cause to be made all necessary repairs, renewals, replacements, betterments and
improvements thereof, all as, in the judgment of the Company, may be necessary
so that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided that nothing in this Section
4.05 shall prevent the Company from discontinuing the operation or maintenance
of any of such Property if such discontinuance is, in the judgment of the
Company, desirable in the conduct of its business or the business of any of its
Restricted Subsidiaries.

     SECTION 4.06.  Payment of Taxes and Other Claims.  The Company shall pay
                    ---------------------------------                        
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all material taxes, assessments and governmental charges levied
or imposed upon the Company or any of its Restricted Subsidiaries or upon the
income, profits or Property of the Company or any of its Restricted Subsidiaries
and (b) all material lawful claims for labor, materials and supplies which, if
unpaid, might by law become a Lien upon the Property of the Company or any of
its Restricted Subsidiaries; provided that the Company shall not be required to
pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings upon stay of execution or the enforcement
thereof and for which adequate reserves in accordance with GAAP or other
appropriate provision has been made.

     SECTION 4.07.  Repurchase at the Option of Holders upon a Change of
                    ----------------------------------------------------
Control.  (a) Upon the occurrence of a Change of Control, each Holder shall have

thereof), plus accrued and unpaid interest, if any, to the Change of Control
Payment Date.

     (b) Within 30 calendar days of the date of any Change of Control, the
Company, or the Trustee at the request and expense of the Company, shall send to

     the address specified in the notice, prior to the close of business on the
     third Business Day preceding the Change of Control Payment Date;

        (vi) that any Holder shall be entitled to withdraw such election if the

     SECTION 4.08.  Repurchase at the Option of Holders upon Failure to
                    ---------------------------------------------------
Consummate the CCI Transaction.
- ------------------------------ 
 
     (a) If the CCI Transaction is not consummated by March 31, 1998 (or, if the
CCI Transaction has not been consummated by March 31, 1998 solely as a result of
CCI having failed to receive all required regulatory approvals or consents, by
May 30, 1998) (the "Termination Date") or is terminated prior to such date, each
Holder shall have the right to require the Company to purchase such Holder's
Notes, in whole or in part, in a principal amount that is an integral multiple
of $1,000 (the "CCI Transaction Put Option"), pursuant to the offer described in
Section 4.08(b) hereof ("CCI Transaction Put Option Offer"), at a purchase price
(the "CCI Transaction Purchase Price") in cash equal to 100 percent of the
principal amount of such Notes (or portions thereof), plus accrued and unpaid
interest, if

                                      56
<PAGE>
 
any, to the CCI Transaction Put Option Exercise Date (as defined herein).  If
the CCI Transaction is consummated on a date subsequent to the Termination Date
and such consummation date is the date of, or prior to, the date of receipt by
the Paying Agent of such Holder's notice of intention to exercise the CCI
Transaction Put Option, such Holder shall be deemed to have waived its right to
exercise its CCI Transaction Put Option, notwithstanding the date of such
Holder's notice or the date of mailing of such notice.
 
     (b) If the CCI Transaction is not consummated by the Termination Date
or is terminated on a date prior thereto, the Company or Trustee, at the request
and expense of the Company, shall, within fifteen (15) days following the
Termination Date (in the event of the non-consummation of the CCI Transaction)

Indenture.

     The Company shall deliver written notice to the Trustee within 30 calendar
days after any executive officer of the Company becomes aware of the occurrence

Event of Default specified in Section 6.01(g) or Section 6.01(h) hereof) occurs
and is continuing, then and in every such case, the Trustee by a notice in
writing to the Company may, and at the direction of the Holders of not less than
25 percent of the outstanding aggregate principal amount of Notes by a notice in
writing to the Company and the Trustee, shall declare the Default Amount and any
accrued and unpaid interest on all Notes then outstanding to be immediately due

hereof occurs, the Default Amount and any accrued and unpaid interest on all
Notes then outstanding shall

                                      79
<PAGE>
 
ipso facto become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder of Notes.

          In the event of a declaration of acceleration because an Event of
Default set forth in Section 6.01(e) hereof has occurred and is continuing, such
declaration of acceleration shall be automatically rescinded and annulled if the
event of default triggering such Event of Default pursuant to Section 6.01(e)
hereof shall be remedied, or cured, or waived by the holders of the relevant
Indebtedness, within 60 calendar days after such event of default; provided no
judgment or decree for the payment of the money due on the Notes has been
obtained by the Trustee as hereinafter in this Article VI provided.

          At any time after a declaration of acceleration with respect to Notes
has been made and before a judgment or decree for payment of the money due has
been obtained by the Trustee as hereinafter in this Article VI provided, the
Holders of a majority in principal amount of the outstanding Notes, by written
notice to the Company and the Trustee, may rescind and annul such declaration
and its consequences if,

                                 (a) the Company has paid or deposited with the
Trustee a sum sufficient to pay:

                                 (i) all overdue installments of interest on all
Notes,

          (ii) the principal of (and premium, if any, on) any Notes which have
become due otherwise than by such declaration of acceleration and interest
thereon at the rate or rates prescribed therefor in such Notes,

          (iii)  to the extent that payment of such interest is lawful, interest
on the Defaulted Interest at the rate prescribed therefor in the Notes and this
Indenture, and

          (iv)  all moneys paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel and all other amounts due to the Trustee pursuant to
Section 7.07 hereof; and

          (b) all Events of Default with respect to the Notes, other than the
non-payment of the principal of Notes which have become due solely by such
declaration of acceleration, have been cured or waived by the Holders as
provided herein.

                                 No such rescission shall affect any subsequent
Default or impair any right consequent thereon.

          SECTION 6.03.  Other Remedies.  The Company covenants that if an Event
                         --------------                                         
of Default specified in Section 6.01(a) or Section 6.01(b) occurs the Company
shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the
Holders, the whole amount

                                      80
<PAGE>
 
then due and payable on the Notes for principal (and premium, if any) and
interest and, to the extent that payment of such interest shall be legally
enforceable, interest upon the overdue principal (and premium, if any) and upon
Defaulted Interest, at the rate or rates prescribed therefor in such Notes; and,
in addition thereto, such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel and
all other amounts due to the Trustee pursuant to Section 7.07 hereof.

          If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may and, at the
direction of the Holders of not less than a majority of the outstanding
aggregate principal amount of the Notes, shall institute a judicial proceeding
for the collection of the sums so due and unpaid, and may prosecute such
proceeding to judgment or final decree, and may enforce the same against the
Company or any other obligor upon such Notes and collect the moneys adjudged or
decreed to be payable in the manner provided by law out of the Property and
assets of the Company or any other obligor upon such Notes, wherever situated.

          If an Event of Default with respect to the Notes occurs and is
continuing, the Trustee may in its discretion proceed to protect and enforce its
rights and the rights of the Holders by such appropriate judicial proceedings as
the Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

a majority in principal amount of the outstanding Notes may, on behalf of the
Holders of all the Notes, waive any past Default and its consequences under this
Article VI, except a Default (a) in the payment of the principal of (or
premium, if any) or interest on, any Note, or (b) in respect of a covenant or
provision hereof which under Section 9.02 hereof cannot be modified or amended
without the consent of the Holders of each outstanding Note affected.

          SECTION 6.05.  Control by Majority.  The Holders of not less than a
                         -------------------                                 
majority in principal amount of the outstanding Notes shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee; provided that

          (a) such direction shall not be in conflict with any rule of law or
with this Indenture or unduly prejudicial to the rights of other Holders and
would not subject the Trustee to personal liability, and

          (b) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction.

          SECTION 6.06.  Limitation on Suits.  No Holder of Notes shall have any

right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless:

          (a) such Holder has previously given written notice to the Trustee of
a continuing Event of Default with respect to the Notes;

          (b) the Holders of not less than 25 percent in principal amount of the
outstanding Notes shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default in its own name as Trustee
hereunder;

          (c) such Holder or Holders have offered and, if requested, provided to
the Trustee security or indemnity satisfactory to the Trustee in its reasonable
discretion against the costs, expenses and liabilities to be incurred in
compliance with such request;

          (d) the Trustee for 30 calendar days after its receipt of such notice,
request and offer of indemnity has failed to institute any such proceeding; and

          (e) no direction inconsistent with such written request has been given
to the Trustee during such 30-day period by the Holders of a majority in
principal amount of the outstanding Notes;

in any event, it being understood and intended that no one or more Holders of
Notes shall have any right in any manner whatever by virtue of, or by availing
of, any provision of this Indenture to affect, disturb or prejudice the rights
of any other Holders of Notes, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all Holders of Notes.

payment of principal of (premium, if any) and interest on the Notes held by such
Holder, on or after the respective due dates expressed in the Notes or the
redemption dates or purchase dates provided for therein, or to bring suit for
the enforcement of any such payment on or after such respective dates, shall be
absolute and unconditional and shall not be impaired or affected without the
consent of such Holder.

          SECTION 6.08.  Trustee May File Proofs of Claim.  In case of the
                         --------------------------------                 
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceedings, or any voluntary or involuntary case under United States bankruptcy
laws, as now or hereafter constituted, relative to the Company or any other
obligor upon the Notes or the Property and assets of the Company or of such
other obligor

                                      82

or their creditors, the Trustee (irrespective of whether the principal of such
Notes shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise, (i) to file and
prove a claim for the whole amount of principal (and premium, if any) and
interest owing and unpaid in respect of the Notes, to file such other papers or
documents and to take such other actions, including participating as a member or

of the Trustee, its agents and counsel and all other amounts due to the Trustee
pursuant to Section 7.07 hereof) and of the Holders allowed in such judicial
proceeding, and (ii) to collect and receive any moneys or other Property payable
or deliverable on any such claims and to distribute the same; and any receiver,
assignee, trustee, custodian, liquidator, sequestrator (or other similar
official) in any such proceeding is hereby authorized by each Holder to make
such 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 counsel, and any other amounts due the
Trustee under Section 7.07 hereof.  Nothing contained herein 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 Notes 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 6.09.  Priorities.  Any money collected by the Trustee
                         ----------

suit instituted by the Trustee, to any suit instituted by any Holder, or group
of Holders, holding in the aggregate more than 10 percent in principal amount of
the outstanding Notes, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of (or premium, if any) or interest

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.

prosecuted and enforced by the Trustee without the possession of any of the
Notes or the production thereof in any proceeding relating thereto, and any such
proceeding instituted by the Trustee shall be brought in its own name, as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Notes.

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

provided in Section 2.09 hereof, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders is intended to be exclusive of any
other right or remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

          SECTION 6.15.  Delay or Omission Not Waiver.  No delay or omission of
                         ----------------------------                          
the Trustee or of any Holder of any Note to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article VI or by law to the Trustee or to

and is continuing, the Trustee shall exercise the rights and powers vested in it
by this Indenture and shall 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 of which a
Trust Officer has actual knowledge: (i) 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 (ii) 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; provided that in
the case of any such certificates or opinions that by any provision of this
Indenture are specifically required to be furnished to the Trustee, the Trustee
shall examine such certificates and opinions to determine whether or not they
conform to the requirements of this Indenture.
 
          (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct; provided that:  (i) this paragraph (c) shall not limit the effect of
paragraph (b) of this Section 7.01; (ii) 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 (iii) the
Trustee shall not be

                                      85

liable with respect to any action it takes or omits to take in good faith in

          (e) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur any 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 for believing that
repayment of such funds or adequate indemnity against such risk of liability is
not reasonably assured to it.

          (f) 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 Article VII and to the provisions of the Trust
Indenture Act.

          SECTION 7.02.  Rights of Trustee.   (a)  The Trustee may rely on any

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 any
Officers' Certificate or Opinion of Counsel.

for the misconduct or negligence of any such agent; provided that such agent was
appointed with due care by the Trustee.

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

Event of Default under Section 6.01(c), 6.01(d), 6.01(e) or 6.01(f) hereof, of
the identity of any Restricted Subsidiary or of the existence of any Change of
Control or Asset Sale unless either (i) a Trust Officer shall have actual
knowledge thereof, or (ii) the Trustee shall have received notice thereof in
accordance with Section 10.02 hereof from the Company or any Holder of Notes.

          (f) The Trustee may consult with counsel and the written advice of

investigation, it shall be entitled to examine the books, records and premises
of the Company, personally or by agent or attorney.

the Trustee, or exercising any trust or power conferred upon the Trustee, under
this Indenture.

Agent or Note Registrar, in its individual or any other capacity, may become the
owner or pledgee of Notes and may otherwise deal with the Company or its
Affiliates with the same rights it would have if it were not Trustee, Paying

                         ------------------                                    
occurrence of any Default hereunder known to a Trust Officer with respect to the

addresses appear in the Note Register, notice of such Default hereunder known to
the Trustee, unless such Default shall have been cured or waived; provided that,

such notice if and so long as the board of directors, the executive committee or
a trust committee of directors and/or Trust Officers of the Trustee in good
faith determine that the withholding of such notice is in the interest of the
Holders.

          SECTION 7.06.  Preservation of Information; Reports by Trustee to
                         --------------------------------------------------
Holders.  (a) The Company shall furnish or cause to be furnished to the Trustee:
- -------

preceding such Interest Payment Date, and

          (ii) at such other times as the Trustee may request in writing, within
30 calendar days after the receipt by the Company of any such request, a list of
similar form and content as of a date not more than 15 calendar days prior to
the time such list is furnished;

provided that if and so long as the Trustee shall be the Note Registrar for the
Notes, no such list need be furnished with respect to the Notes.

          (b) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 7.06(a) hereof and the
names and addresses of Holders received by the Trustee in its capacity as Note
Registrar, if so acting.  The Trustee may destroy any list furnished to it as

          (c) Holders may communicate as provided in Section 312(b) of the Trust
Indenture Act with other Holders with respect to their rights under this
Indenture or under the Notes.

          (d) Each Holder of Notes, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee shall
be held accountable by reason of the disclosure of any such information as to
the names and addresses of the Holders in accordance with this Section 7.06,
regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing any material pursuant
to a request made under this Section 7.06.

          (e) Within 60 calendar days after April 15 of each year commencing
with the year 1998, the Trustee shall transmit by mail to all Holders of Notes,
a brief report dated as of such April 15 if and to the extent required under
Section 313(a) of the Trust Indenture Act.

          (f) The Trustee shall comply with Sections 313(b) and 313(c) of the
Trust Indenture Act.

          (g) A copy of each report described in Section 7.06(e) hereof shall,
at the time of its transmission to Holders, be filed by the Trustee with each

Trustee of any stock exchange upon which the Notes are listed.

          SECTION 7.07.  Compensation and Indemnity.  The Company shall pay to
                         --------------------------                           
the Trustee from time to time reasonable compensation for its services. The
Company shall reimburse the Trustee upon request for all reasonable out-of-
pocket expenses incurred or

                                      88
<PAGE>
 
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 and counsel.  The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust.

          The Company shall indemnify the Trustee for, and hold it harmless
against, any and all loss, liability or expense (including reasonable attorneys'
fees) arising out of or incurred by it in connection with the acceptance or
administration of the trust created by this Indenture and the performance of its
duties hereunder, except as set forth in the next paragraph.  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.  The Company shall defend any such claim and the
Trustee shall cooperate in the defense of such claim.  The Trustee may have
separate counsel and the Company shall pay the reasonable fees and expenses of
such counsel.  The Company need not pay for any settlement made without its
consent, which consent shall not be unreasonably withheld.

          The Company need not reimburse any expense or indemnify against any
loss, liability or expense incurred by the Trustee through the Trustee's own
willful misconduct, negligence or bad faith.

          To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a Lien prior to the Notes on all money or property held or
collected by the Trustee other than money or property held in trust to pay
principal of, premium, if any, and interest on, particular Notes.

          The Company's payment obligations pursuant to this Section 7.07 shall
survive the resignation or removal of the Trustee and discharge of this
Indenture.  Subject to any other rights available to the Trustee under
applicable bankruptcy law, when the Trustee incurs expenses after the occurrence
of a Default specified in Section 6.01(g) or Section 6.01(h) hereof, the
expenses are intended to constitute expenses of administration under bankruptcy
law.

          SECTION 7.08.  Replacement of Trustee.  (a)  No resignation or removal
                         ----------------------                                 
of the Trustee and no appointment of a successor Trustee pursuant to this
Article VII shall become effective until the acceptance of appointment by the
successor Trustee under this Section 7.08.

          (b) The Trustee may resign at any time by giving written notice
thereof to the Company.  If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 calendar days after the
giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.


                                      89
<PAGE>
 
          (c) The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the outstanding Notes, delivered to the Trustee
and to the Company.

          (d)  If at any time:

               (i) the Trustee shall fail to comply with Section 310(b) of the
          Trust Indenture Act after written request therefor by the Company or
          by any Holder who has been a bona fide Holder of a Note for at least
          six months, unless the Trustee's duty to resign is stayed in
          accordance with the provisions of Section 310(b) of the Trust
          Indenture Act; or

               (ii) the Trustee shall cease to be eligible under Section 7.10
          hereof and shall fail to resign after written request therefor by the
          Company or by any such Holder; or

               (iii) the Trustee shall become incapable of acting or a decree or
          order for relief by a court having jurisdiction in the premises shall
          have been entered in respect of the Trustee in an involuntary case
          under the United States bankruptcy laws, as now or hereafter
          constituted, or any other applicable Federal or state bankruptcy,
          insolvency or similar law; or a decree or order by a court having
          jurisdiction in the premises shall have been entered for the
          appointment of a receiver, custodian, liquidator, assignee, trustee,
          sequestrator (or other similar official) of the Trustee or of its
          Property and assets or affairs, or any public officer shall take
          charge or control of the Trustee or of its Property and assets or
          affairs for the purpose of rehabilitation, conservation, winding up or
          liquidation; or

               (iv) the Trustee shall commence a voluntary case under the United
          States bankruptcy laws, as now or hereafter constituted, or any other
          applicable Federal or state bankruptcy, insolvency or similar law or
          shall consent to the appointment of or taking possession by a
          receiver, custodian, liquidator, assignee, trustee, sequestrator (or
          other similar official) of the Trustee or its Property and assets or
          affairs, or shall make an assignment for the benefit of creditors, or
          shall admit in writing its inability to pay its debts generally as
          they become due, or shall take corporate action in furtherance of any
          such action,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to the Notes, or (ii) subject to Section 6.10 hereof, any
Holder who has been a bona fide Holder of a Note for at least six months may, on
behalf of such Holder and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee for the Notes.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by or pursuant to a Board Resolution, shall promptly appoint a
successor Trustee.  If, within one year after such

                                      90
<PAGE>
 
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee shall be appointed by the Holders of a majority in principal
amount of the outstanding Notes delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with this Section 7.08, become the successor
Trustee and to that extent replace any successor Trustee appointed by the
Company.  If no successor Trustee shall have been so appointed by the Company or
the Holders and shall have accepted appointment in the manner hereinafter
provided, any Holder that has been a bona fide Holder of a Note for at least six
months may, subject to Section 6.10 hereof, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee and each appointment of a successor Trustee by mailing written
notice of such resignation, removal and appointment by first class mail, postage
prepaid, to the Holders as their names and addresses appear in the Note
Register.  Each notice shall include the name of the successor Trustee with
respect to the Notes and the address of its Corporate Trust Office.

          (g) In the event of an appointment hereunder of a successor Trustee,
each such successor Trustee so appointed shall execute, acknowledge and deliver
to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee but, on request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee, and shall duly assign, transfer and
deliver to such successor Trustee all Property and money held by such former
Trustee hereunder, subject to its Lien, if any, provided for in Section 7.07
hereof.

          (h) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in Section 7.08(g) hereof.

          (i) No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article VII and under the Trust Indenture Act.

          SECTION 7.09.  Successor Trustee by Merger.  Any corporation into
                         ---------------------------                       
which the Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any corporation
succeeding to all or substantially all of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder; provided that such
corporation shall be otherwise qualified and eligible under this Article VII and
under the

                                      91
<PAGE>
 
Trust Indenture Act, without the execution or filing of any paper or any further
act on the part of any of the parties hereto.  In case any Notes shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Notes so authenticated with the same effect
as if such successor Trustee had itself authenticated such Notes.  In the event
that any Notes shall not have been authenticated by such predecessor Trustee,
any such successor Trustee may authenticate and deliver such Notes, in either
its own name or that of its predecessor Trustee, with the full force and effect
which this Indenture provides for the certificate of authentication of the
Trustee.

          SECTION 7.10.  Eligibility; Disqualification. There shall at all times
                         -----------------------------

          the United States of America, any State or Territory thereof or the
          District of Columbia, authorized under such laws to exercise corporate
          trust powers, and subject to supervision or examination by Federal,
          State, Territorial or District of Columbia authority, or

               (ii) a corporation or other Person organized and doing business

          subject to supervision or examination by authority of such foreign
          government or a political subdivision thereof substantially equivalent
          to supervision or examination applicable to United States
          institutional trustees,

in either case having a combined capital and surplus of at least $25,000,000.

          If such Person publishes reports of condition at least annually,
pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section 7.10, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.
Neither the Company nor any Affiliate of the Company shall serve as Trustee
hereunder. If at any time the Trustee shall cease to be eligible to serve as
Trustee hereunder pursuant to the provisions of this Section 7.10, it shall
resign immediately in the manner and with the effect specified in this Article
VII.

          If the Trustee has or shall acquire any "conflicting interest" within
the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the
Company shall in all respects comply with the provisions of Section 310(b) of
the Trust Indenture Act.  Nothing herein shall prevent the Trustee from filing
with the Commission the application referred to in the penultimate paragraph of
Section 310(b) of the Trust Indenture Act.

discharged from its obligations with respect to such Notes as provided in this
Section 8.02 on and after the date the conditions set forth in Section 8.04
hereof are satisfied (hereinafter called "Defeasance").  For this purpose, such
Defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by such Notes and to have satisfied all its
other obligations under such Notes and this Indenture insofar as such Notes are

          Subject to compliance with this Article VIII, the Company may exercise
its option to have this Section 8.02 applied to the outstanding Notes (in whole
and not in part) notwithstanding the prior exercise of its option to have
Section 8.03 hereof applied to such Notes.

          SECTION 8.03.  Covenant Defeasance.  Upon the Company's exercise of
                         -------------------                                 
its option to have this Section 8.03 applied to the outstanding Notes (in whole
and not in part), (i) the Company shall be released from its obligations under
Section 5.01(c) and (d), Sections 4.05 through 4.19, inclusive, and any covenant
added to this Indenture subsequent to the Issue Date pursuant to Section 9.01
hereof, (ii) the occurrence of any event specified in Section 6.01(c) or Section
6.01(d) hereof, with respect to any of Section 5.01(c) and (d), Sections 4.05
through 4.19, inclusive, and any covenant added to this Indenture subsequent to
the Issue Date pursuant to Section 9.01 hereof, shall be deemed not to be or
result in an Event of Default, in each case with respect to such Notes as
provided in this Section 8.03 on and after the date the conditions set forth in
Section 8.04 hereof are satisfied (hereinafter called "Covenant Defeasance").
For this purpose, such Covenant Defeasance means that, with respect to such
Notes, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such specified
Section (to the extent so specified in the case of Sections 6.01(c) and 6.01(d)
hereof), whether directly or indirectly by reason of any reference elsewhere
herein to any such Section or by reason of any reference in any such Section to
any other provision herein or in any other document; but the remainder of this
Indenture and such Notes shall be unaffected thereby.

          SECTION 8.04.  Conditions to Defeasance or Covenant Defeasance.  The
                         -----------------------------------------------      
following shall be the conditions to the application of Section 8.02 or Section
8.03 hereof to the outstanding Notes:

          (a)  The Company shall irrevocably have deposited or caused to be
deposited with the Trustee as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to the benefits of the Holders of such Notes, (i) money in an amount, or (ii)
U.S. Government Obligations which through the scheduled payment of principal and
interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment, money in an amount, or
(iii) a combination thereof, in each case sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or any such other qualifying trustee)
to pay and discharge, the principal of and any installment of interest on such
Notes on the respective Stated Maturities thereof, in accordance with the terms
of this Indenture and such Notes.

          (b)  In the event of an election to have Section 8.02 hereof apply to
the outstanding Notes, 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

                                      94
<PAGE>
 
applicable Federal income tax law, in either case (i) or (ii) to the effect
that, and based thereon such opinion shall confirm that, the Holders of such
Notes will not recognize gain or loss for Federal income tax purposes as a
result of the deposit, Defeasance and discharge to be effected with respect to
such Notes and will be subject to Federal income tax on the same amount, in the
same manner and at the same times as would be the case if such deposit,
Defeasance and discharge were not to occur.

          (c)  In the event of an election to have Section 8.03 hereof apply to
the outstanding Notes, the Company shall have delivered to the Trustee an
Opinion of Counsel reasonably acceptable to the Trustee to the effect that the
Holders of such Notes will not recognize gain or loss for Federal income tax
purposes as a result of the deposit and Covenant Defeasance to be effected with
respect to such Notes and will be subject to Federal income tax on the same
amount, in the same manner and at the same times as would be the case if such
deposit and Covenant Defeasance were not to occur.

          (d)  No Default or Event of Default with respect to the outstanding
Notes shall have occurred and be continuing at the time of such deposit after
giving effect thereto or at any time on or prior to the 91st calendar day after
the date of such deposit (it being understood that this condition shall not be
deemed satisfied until after such 91st calendar day).

          (e)  Such Defeasance or Covenant Defeasance shall not cause the
Trustee to have a conflicting interest within the meaning of the Trust Indenture
Act (assuming for the purpose of this clause (e) that all Notes are in default
within the meaning of such Act).

          (f)  Such Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a default under, any other agreement or
instrument to which the Company is a party or by which it is bound.

          (g)  Such Defeasance or Covenant Defeasance shall not result in the
trust arising from such deposit constituting an investment company within the
meaning of the Investment Company Act of 1940, as amended, unless such trust
shall be registered under such Act or exempt from registration thereunder.

          (h)  The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent with respect to such Defeasance or Covenant Defeasance have been
complied with.

          SECTION 8.05.  Deposited Money and U.S. Government Obligations to be
                         -----------------------------------------------------
Held in Trust; Miscellaneous Provisions.  All money and U.S. Government
- ---------------------------------------                                
Obligations (including the proceeds thereof) deposited with the Trustee pursuant
to Section 8.04 hereof in respect of the outstanding Notes shall be held in
trust and applied by the Trustee, in accordance with the provisions of such
Notes and this Indenture, to the payment, either directly or through any such
Paying Agent as the Trustee may determine, to the Holders of such Notes, of all

                                      95
<PAGE>
 
sums due and to become due thereon in respect of principal and any premium and
interest, but money so held in trust need not be segregated from other funds
except to the extent required by law.  The Company shall pay and indemnify the
Trustee against any tax, fee or other charge imposed on or assessed against the
U.S. Government Obligations deposited pursuant to Section 8.04 hereof or the
principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of outstanding
Notes.

          Anything in this Article VIII to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company Order
any money or U.S. Government Obligations held by it as provided in Section 8.04
hereof which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof that would then be required to be
deposited to effect the Defeasance or Covenant Defeasance, as the case may be,
with respect to the outstanding Notes.

          The Trustee and the Paying Agent shall pay to the Company upon written
request any money held by them for the payment of principal, premium, if any, or
interest that remains unclaimed for two years; provided that the Trustee or such
                                               --------                         
Paying Agent before being required to make any payment may cause to be published
at the expense of the Company once in a newspaper of general circulation in the
City of New York or mail to each Holder entitled to such money at such Holder's
address (as set forth in the Note Register) notice that such money remains
unclaimed and that after a date specified therein (which shall be at least 30
days from the date of such publication or mailing) any unclaimed balance of such
money then remaining will be repaid to the Company.  After payment to the
Company, Holders entitled to such money must look to the Company for payment as
general creditors unless an applicable law designates another Person, and all
liability of the Trustee and such Paying Agent with respect to such money shall
cease.

          SECTION 8.06.  Reinstatement.  If the Trustee or Paying Agent is
                         -------------                                    
unable to apply any money in accordance with this Article VIII with respect to
any Notes by reason of any order or judgement of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application then
the obligations under this Indenture and such Notes from which the Company has
been discharged or released pursuant to Sections 8.02 or 8.03 hereof shall be
revived and reinstated as though no deposit had occurred pursuant to this
Article VIII with respect to such Notes, until such time as the Trustee or
Paying Agent is permitted to apply all money held in trust pursuant to Section
8.05 hereof with respect to such Notes in accordance with this Article VIII;
provided that if the Company makes any payment of principal of or any premium or
interest on any such Note following such reinstatement of its obligations, the
Company shall be subrogated to the rights (if any) of the Holders of such Notes
to receive such payment from the money so held in trust.

                                  AMENDMENTS

          SECTION 9.01.   Without Consent of Holders.   The Company and the
                          --------------------------                       
Trustee may, at any time, and from time to time, without notice to or consent of
any Holder of Notes, enter into one or more indentures supplemental hereto, in

          (e)  to evidence and provide for the acceptance of appointment
hereunder of a successor Trustee; or

          (f)  to secure the Notes; or

          (g)  to cure any ambiguity herein, or to correct or supplement any
provision hereof which may be inconsistent with any other provision hereof or to
add any other provisions with respect to matters or questions arising under this
Indenture; provided that such actions shall not adversely affect the interests
           --------                                                           
of the Holders of Notes in any material respect; or

          (h)  to comply with the requirements of the Commission in order to
effect or maintain the qualification of this Indenture under the Trust Indenture
Act.

          SECTION 9.02.  With Consent of Holders.  With the consent of the
                         -----------------------                          
Holders of not less than a majority in principal amount of the outstanding
Notes, by Act of said Holders delivered to the Company and the Trustee, the
Company and the Trustee may enter into one or more indentures supplemental
hereto for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of modifying in any
manner the rights of the Holders; provided that no such supplemental indenture
shall, without the consent of the Holder of each outstanding Note,

                                      97
<PAGE>
 
          (a)  change the Stated Maturity of the principal of, or any
installment of interest on, any Note, or alter the redemption provisions
thereof, or reduce the principal amount thereof (or any premium, if any), or the
interest thereon, that would be due and payable upon Maturity thereof, or change
the place of payment where, or the coin or currency in which, any Note or any
premium or interest thereon is payable, or impair the right to institute suit
for the enforcement of any such payment on or after the Maturity thereof; or

          (b)  reduce the percentage in principal amount of the outstanding
Notes, the consent of whose Holders is required for any such supplemental
indenture; or

          (c)  modify any of the provisions of Section 6.04 hereof, except to
increase any percentage set forth therein or to provide that certain other
provisions of this Indenture cannot be modified or waived without the consent of
the Holder of each outstanding Note affected thereby; or

          (d)  subordinate in right of payment, or otherwise subordinate, the
Notes to any other Indebtedness; or

          (e)  modify any of the provisions of this Section 9.02, except to
increase any percentage set forth herein or to provide that certain other
provisions of this Indenture cannot be modified or waived without the consent of
the Holder of each outstanding Note affected thereby.

          It shall not be necessary for any Act of Holders under this Section
9.02 to approve the particular form of any proposed supplemental indenture, but
it shall be sufficient if such Act shall approve the substance thereof.

          SECTION 9.03.  Effect of Supplemental Indentures.  Upon the execution
                         ---------------------------------                     
of any supplemental indenture under this Article IX, this Indenture shall be
modified in accordance therewith, and such supplemental indenture shall form a
part of this Indenture for all purposes; and every Holder of Notes theretofore
or thereafter authenticated and delivered hereunder shall be bound thereby.

          SECTION 9.04.  Compliance with Trust Indenture Act.  Every amendment
                         -----------------------------------                  
or supplement to this Indenture or the Notes shall comply with the Trust
Indenture Act as then in effect.

          SECTION 9.05.  Revocation and Effect of Consents and Waivers.  A
                         ---------------------------------------------    
consent to an amendment, supplement or a waiver by a Holder of a Note shall bind
the Holder and every subsequent Holder of such Note or portion of such Note that
evidences the same debt as the consenting Holder's Note, even if notation of the
consent or waiver is not made on such Note; provided that any such Holder or
                                            --------                        
subsequent Holder may revoke the consent or waiver as to such Holder's Note or
portion of such Note if the Trustee receives the notice of

                                      98
<PAGE>
 
revocation at least one day prior to the date the amendment, supplement or
waiver becomes effective.  After an amendment, supplement or waiver becomes
effective pursuant to this Article IX, it shall bind every Holder.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders 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 Holders 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
calendar days after such record date.

          SECTION 9.06.  Notation on or Exchange of Notes.  If a supplemental
                         --------------------------------                    
indenture changes the terms of a Note, the Trustee may require the Holder
thereof to deliver such Note to the Trustee.  The Trustee may place an
appropriate notation on such Note regarding the changed terms and return it to
the Holder.  Alternatively, if the Company or the Trustee so determines, the
Company in exchange for such Note shall issue and the Trustee shall authenticate
a new Note that reflects the changed terms.  Failure to make the appropriate
notation or to issue a new Note shall not affect the validity of such amendment
or supplement.

          SECTION 9.07.  Trustee to Execute Supplemental Indentures.  The
                         ------------------------------------------      
Trustee shall execute any supplemental indenture authorized pursuant to this
Article IX if such supplemental indenture does not adversely affect the rights,
duties, liabilities or immunities of the Trustee. If it does, the Trustee may,
but shall not be required to, execute such supplemental indenture.  In executing
any supplemental indenture, the Trustee shall be (subject to Section 7.01
hereof) fully protected in relying upon an Officers' Certificate and an Opinion
of Counsel, which shall not be at the expense of the Trustee, stating that the
execution of such supplemental indenture is authorized or permitted by this
Indenture.

                          ----------------------------                       
that any provision of this Indenture limits, qualifies or conflicts with the
duties imposed by, or with another provision (an "incorporated provision")
included in this Indenture by operation of, Sections 310 to 318, inclusive, of
the Trust Indenture Act, such imposed duties or incorporated provision shall
control.

          SECTION 10.02.  Notices.  Any notice or communication shall be in

notice or communication mailed to a Holder shall be sent to the Holder by first
class mail, postage prepaid, at the Holder's address as it appears in the Note
Register and shall be duly given if so sent within the time prescribed.  Failure
to mail a notice or communication to a Holder or any defect in it shall not
affect its sufficiency with respect to other Holders.  If a notice or
communication is mailed to the Company, the Trustee or a Holder in the manner
provided above, it is duly given, whether or not the addressee receives it.  In
case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give notice by mail to Holders, then
such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

          SECTION 10.03.  Certificate and Opinion as to Conditions Precedent.
                          --------------------------------------------------

certificate or opinion with respect to compliance with a covenant or condition
provided for in this Indenture (other than pursuant to Section 4.20 hereof)
shall include: (a) a statement that the individual making such certificate or
opinion has read such covenant or condition; (b) a brief statement as to the

or investigation as is necessary to enable such person to express an informed
opinion as to whether or not such covenant or condition has been complied with;
and (d) a statement as to whether or not, in the opinion of such individual,
such covenant or condition has been complied with; provided that, with respect
to matters of fact, an Opinion of Counsel may rely on an Officers' Certificate
or certificates of public officials.

          SECTION 10.05.  Rules by Trustee, Paying Agent and Note Registrar.
                          -------------------------------------------------  
The Trustee may make reasonable rules for action by or a meeting of Holders, and
any Note Registrar and Paying Agent may make reasonable rules for their
functions; provided that no such rule shall conflict with terms of this
Indenture or the Trust Indenture Act.

on the next succeeding day that is a Business Day, and no interest shall accrue
with respect to that payment during the intervening period.  If a regular record
date is a date that is not a Business Day, such record date shall not be
affected.

of, such obligations or their creation, solely by reason of its past, present or
future status as a controlling Person, director, officer, employee, incorporator

          (ii)   keep the Registered Exchange Offer open for not less than 30
     days and not more than 45 days after the date notice thereof is mailed to

     New Securities equal in principal amount to the Securities of such Holder

          (e)    The Purchasers and the Company acknowledge that, pursuant to
interpretations by the Commission's staff of Section 5 of the Act, and in the
absence of an applicable exemption therefrom, each Exchanging Dealer is required

     Prospectus forming a part of the Exchange Offer Registration Statement, and

     Statement continuously effective under the Act during the Exchange Offer
     Registration Period for delivery by Exchanging Dealers in connection with
     sales of New Securities received pursuant to the Registered Exchange Offer,
     as contemplated by Section 4(h) below.

          (f)    In the event that any Purchaser determines that it is not
eligible to participate in the Registered Exchange Offer with respect to the
exchange of Securities constituting any portion of an unsold allotment, at the
request of such Purchaser, the Company shall issue and deliver to such Purchaser
or the party purchasing New Securities registered under a Shelf Registration
Statement as contemplated by Section 3 hereof from such Purchaser, in exchange
for such Securities, a like principal amount of New Securities. The Company
shall seek to cause the CUSIP Service Bureau to issue the same CUSIP number for
such New Securities as for New Securities issued pursuant to the Registered
Exchange Offer.

applicable interpretations thereof by the Commission's staff, the Company
determines upon advice of its outside counsel that it is not permitted to effect
the Registered Exchange Offer as contemplated by Section 2 hereof, or (ii) for
any other reason the Exchange Offer Registration Statement has not been filed
with the Commission within 60 days of the Closing Date, or (iii) for any other
reason the Registered Exchange Offer is not consummated within 180 days of the
Closing Date, or (iv) any Purchaser so requests with respect to Securities held
by it following consummation of the Registered Exchange Offer, or (v) in the
case of any Purchaser that participates in the Registered Exchange Offer or
acquires New Securities pursuant to Section 2(f) hereof, such Purchaser does not
receive freely tradeable New Securities in exchange for Securities constituting
any portion of an unsold allotment (it being understood that, for purposes of
this Section 3, (x) the requirement that a Purchaser deliver a Prospectus
containing the information required by Items 507 and/or 508 of Regulation S-K
under the Act in connection with sales of New Securities acquired in exchange
for such Securities shall result in such New Securities being not "freely
tradeable" but (y) the requirement that an Exchanging Dealer deliver a
Prospectus in connection with sales of New Securities acquired in the Registered
Exchange Offer in exchange for Securities acquired

as a result of market-making activities or other trading activities shall not
result in such New Securities being not "freely tradeable"), the following
provisions shall apply:

          (a) The Company shall as promptly as practicable (but in no event more
than 30 days after so required or requested pursuant to this Section 3), file
with the Commission and thereafter shall use its best efforts to cause to be
declared effective under the Act a Shelf Registration Statement relating to the
offer and sale of the Securities or the New Securities, as applicable, by the
Holders from time to time in accordance with the methods of distribution elected
by such Holders and set forth in such Shelf Registration Statement; provided,
                                                                    -------- 
that with respect to New Securities received by a Purchaser in exchange for
Securities constituting any portion of an unsold allotment, the Company may, if
permitted by current interpretations by the Commission's staff, file a post-
effective amendment to the Exchange Offer Registration Statement containing the
information required by Regulation S-K Items 507 and/or 508, as applicable, in
satisfaction of its obligations under this paragraph (a) with respect thereto,
and any such Exchange Offer Registration Statement, as so amended, shall be
referred to herein as, and governed by the provisions herein applicable to, a
Shelf Registration Statement.

          (b) The Company shall use its best efforts to keep the Shelf
Registration Statement continuously effective in order to permit the Prospectus
forming part thereof to be usable by Holders for a period of two years from the
date the Shelf Registration Statement is declared effective by the Commission or
such shorter period that will terminate when all the Securities or New
Securities, as applicable, covered by the Shelf Registration Statement have been
sold pursuant to the Shelf Registration Statement (in any such case, such period
being called the "Shelf Registration Period").  The Company shall be deemed not
to have used its best efforts to keep the Shelf Registration Statement effective
during the requisite period if it voluntarily takes any action that would result
in Holders of securities covered thereby not being able to offer and sell such
securities during that period, unless (i) such action is required by applicable
law, or (ii) such action is taken by the Company in good faith and for valid
business reasons (not including avoidance of the Company's obligations
hereunder), including the acquisition or divestiture of assets, so long as the
Company promptly thereafter complies with the requirements of Section 4(k)
hereof, if applicable.

          (c) No Holder of Securities may include any of its Securities in any
Shelf Registration Statement pursuant to this
<PAGE>
 
                                                                               8

Agreement unless such Holder furnishes to the Company in writing, within 10 days
after receipt of a request therefor, such information as the Company may
reasonably request for use in connection with any Shelf Registration Statement
or Prospectus or preliminary Prospectus included therein, and each such Holder
agrees to furnish promptly to the Company all information required to be
disclosed in order to make the information previously furnished to the Company
by such Holder not materially misleading.

          4.   Registration Procedures.  In connection with any Shelf
               -----------------------

     contain an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading and (iii) any Prospectus forming part of any
     Registration Statement, and any amendment or supplement to such Prospectus,
     does not include an untrue statement of a material fact or omit to state a
     material fact necessary in order to make the statements, in the light of

     Registration Statement, the Holders of securities covered thereby, and, if
     requested by you or any such Holder, confirm such advice in writing:

               (i)   when a Registration Statement and any amendment thereto has

Dealer, confirm such advice in writing:

               (i)   of the issuance by the Commission of any stop order
          suspending the effectiveness of the Registration Statement or the
          initiation of any proceedings for that purpose;

               (ii)  of the receipt by the Company of any notification with
          respect to the suspension of the qualification of the securities
          included therein for sale in any jurisdiction or the initiation or
          threatening of any proceeding for such purpose; and

               (iii) of the happening of any event that requires the making of
          any changes in the Registration Statement or the Prospectus so that,
          as of such date, the statements therein are not misleading and do not
          omit to state a material fact required to be stated therein or
          necessary to make the statements therein (in the case of the
          Prospectus, in light of the circumstances under which they were made)
          not misleading (which advice shall be accompanied by an instruction to
          suspend the use of the Prospectus until the requisite changes have
          been made).

of any order suspending the effectiveness of any Registration Statement at the
earliest possible time.

          5.   Registration Expenses.  The Company shall bear all expenses
               ---------------------                                      
incurred in connection with the performance of its obligations under Sections 2,
3 and 4 hereof and, in the event of any Shelf Registration Statement, will
reimburse the Holders for the reasonable fees and disbursements of one firm or
counsel designated by the Majority Holders to act as counsel for the Holders in
connection therewith, and, in the case of any Exchange Offer Registration
Statement, will reimburse the Purchasers for the reasonable fees and
disbursements of counsel acting in
<PAGE>
 
                                                                            15

connection therewith.  Notwithstanding the foregoing, the Holders of any
Securities or New Securities being registered on the Shelf Registration
Statement shall pay all agency or brokerage fees and commissions and
underwriting discounts and commissions attributable to the sale of such
Securities or New Securities and the fees and disbursements of any counsel
retained by such Holders other that counsel referred to above.

          6.   Indemnification and Contribution.
               -------------------------------- 

          (a)  In connection with any Registration Statement, the Company agrees
     to indemnify and hold harmless each Holder of securities covered thereby
     (including each Purchaser and, with respect to any Prospectus delivery as
     contemplated in Section 4(h) hereof, each Exchanging Dealer), the
     directors, officers, employees and agents of each such Holder and each
     person who controls any such Holder within the meaning of either the Act or
     the Exchange Act against any and all losses, claims, damages or
     liabilities, joint or several, to which they or any of them may become
     subject under the Act, the Exchange Act or other Federal or state statutory
     law or regulation, at common law or otherwise, insofar as such losses,
     claims, damages or liabilities (or actions in respect thereof) arise out of
     or are based upon any untrue statement or alleged untrue statement of a
     material fact contained in the Registration Statement as originally filed
     or in any amendment thereof, or in any preliminary Prospectus or
     Prospectus, or in any amendment thereof or supplement thereto, or arise out
     of or are based upon the omission or alleged omission to state therein a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, and agrees to reimburse each such
     indemnified party, as incurred, for any legal or other expenses reasonably
     incurred by them in connection with investigating or defending any such
     loss, claim, damage, liability or action; provided, however, that the 
                                               -----------------
     Company will not be liable in any case to the extent that any such
     loss, claim, damage or liability arises out of or is based upon any such
     untrue statement or alleged untrue statement or omission or alleged
     omission made therein in reliance upon and in conformity with written
     information furnished to the Company by or on behalf of any such Holder
     specifically for inclusion therein. This indemnity agreement will be in
     addition to any liability which the Company may otherwise have.

     The Company also agrees to indemnify or contribute to Losses of, as
     provided in Section 6(d), any underwriters of Securities registered under a
     Shelf Registration Statement,
<PAGE>
 
                                                                            16

     their officers and directors and each person who controls such underwriters
     on substantially the same basis as that of the indemnification of the
     Purchaser and the selling Holders provided in this Section 6(a) and shall,
     if requested by any Holder, enter into an underwriting agreement reflecting
     such agreement, as provided in Section 4(q) hereof.

          (b) Each Holder of securities covered by a Registration Statement
     (including each Purchaser and, with respect to any Prospectus delivery as
     contemplated in Section 4(h) hereof, each Exchanging Dealer) severally
     agrees to indemnify and hold harmless (i) the Company, (ii) each of its
     directors, (iii) each of its officers who signs such Registration Statement
     and (iv) each person who controls the Company within the meaning of either
     the Act or the Exchange Act to the same extent as the foregoing indemnity
     from the Company to each such Holder, but only with reference to written
     information relating to such Holder furnished to the Company by or on
     behalf of such Holder specifically for inclusion in the documents referred
     to in the foregoing indemnity. This indemnity agreement will be in addition
     to any liability which any such Holder may otherwise have.

          (c) Promptly after receipt by an indemnified party under this Section
     6 or notice of the commencement of any action, such indemnified party will,
     if a claim in respect thereof is to be made against the indemnifying party
     under this Section 6, notify the indemnifying party in writing of the
     commencement thereof; but the failure so to notify the indemnifying party
     (i) will not relieve it from liability under paragraph (a) or (b) above
     unless and to the extent it did not otherwise learn of such action and such
     failure results in the forfeiture by the indemnifying party of substantial
     rights and defenses and (ii) will not, in any event, relieve the
     indemnifying party from any obligations to any indemnified party other than
     the indemnification obligation provided in paragraph (a) or (b) above. The
     indemnifying party shall be entitled to appoint counsel of the indemnifying
     party's choice at the indemnifying party's expense to represent the
     indemnified party in any action for which indemnification is sought (in
     which case the indemnifying party shall not thereafter be responsible for
     the fees and expenses of any separate counsel retained by the indemnified
     party or parties except as set forth below); provided, however, that such
                                                  --------  -------  
     counsel shall be satisfactory to the indemnified party. Notwithstanding the
     indemnifying party's election to appoint counsel to represent the
     indemnified party in an action, the indemnified party shall
<PAGE>
 
                                                                              17



     have the right to employ separate counsel (including local counsel), and
     the indemnifying party shall bear the reasonable fees, costs and expenses
     of such separate counsel (and local counsel) if (i) the use of counsel
     chosen by the indemnifying party to represent the indemnified party would
     present such counsel with a conflict of interest, (ii) the actual or
     potential defendants in, or targets of, any such action include both the
     indemnified party and the indemnifying party and the indemnified party
     shall have reasonably concluded that there may be legal defenses available
     to it and/or other indemnified parties which are different from or
     additional to those available to the indemnifying party, (iii) the
     indemnifying party shall not have employed counsel satisfactory to the
     indemnified party to represent the indemnified party within a reasonable
     time after notice of the institution of such action or (iv) the
     indemnifying party shall authorize the indemnified party to employ separate
     counsel at the expense of the indemnifying party. An indemnifying party
     will not, without the prior written consent of the indemnified parties,
     settle or compromise or consent to the entry of any judgment with respect
     to any pending or threatened claim, action, suit or proceeding in respect
     of which indemnification or contribution may be sought hereunder (whether
     or not the indemnified parties are actual or potential parties to such
     claim or action) unless such settlement, compromise or consent includes an
     unconditional release of each indemnified party from all liability arising
     out of such claim, action, suit or proceeding.

           (d)  In the event that the indemnity provided in paragraph (a) or (b)
     of this Section 6 is unavailable to or insufficient to hold harmless an
     indemnified party for any reason, then each applicable indemnifying party,
     in lieu of indemnifying such indemnified party, shall have a joint and
     several obligation to contribute to the aggregate losses, claims, damages
     and liabilities (including legal or other expenses reasonably incurred in
     connection with investigating or defending same) (collectively "Losses") to
     which such indemnified party may be subject in such proportion as is
     appropriate to reflect the relative benefits received by such indemnifying
     party, on the one hand, and such indemnified party, on the other hand, from
     the Initial Placement and the Registration Statement which resulted in such
     Losses; provided, however, that in no case shall any Purchaser or any
             --------  -------         
     subsequent Holder of any Security or New Security be responsible, in the
     aggregate, for any amount in excess of the purchase discount or commission
     applicable to such Security, or in the case of a New
<PAGE>
 
                                                                              18

     Security, applicable to the Security which was exchangeable into such New
     Security, as set forth on the cover page of the Final Memorandum, nor shall
     any underwriter be responsible for any amount in excess of the underwriting
     discount or commission applicable to the securities purchased by such
     underwriter under the Registration Statement which resulted in such Losses.
     If the allocation provided by the immediately preceding sentence is
     unavailable for any reason, the indemnifying party and the indemnified
     party shall contribute in such proportion as is appropriate to reflect not
     only such relative benefits but also the relative fault of such
     indemnifying party, on the one hand, and such indemnified party, on the
     other hand, in connection with the statements or omissions which resulted
     in such Losses as well as any other relevant equitable considerations.
     Benefits received by the Company shall be deemed to be equal to the sum of
     (x) the total net proceeds from the Initial Placement (before deducting
     expenses) as set forth on the cover page of the Final Memorandum and (y)
     the total amount of additional interest which the Company was not required
     to pay as a result of registering the securities covered by the
     Registration Statement which resulted in such Losses. Benefits received by
     the Purchasers shall be deemed to be equal to the total purchase discounts
     and commissions as set forth on the cover page of the Final Memorandum, and
     benefits received by any other Holders shall be deemed to be equal to the
     value of receiving Securities or New Securities, as applicable, registered
     under the Act. Benefits received by any underwriter shall be deemed to be
     equal to the total underwriting discounts and commissions, as set forth on
     the cover page of the Prospectus forming a part of the Registration
     Statement which resulted in such Losses. Relative fault shall be determined
     by reference to whether any alleged untrue statement or omission relates to
     information provided by the indemnifying party, on the one hand, or by the
     indemnified party, on the other hand. The parties agree that it would not
     be just and equitable if contribution were determined by pro rata
     allocation or any other method of allocation which does not take account of
     the equitable considerations referred to above. Notwithstanding the
     provisions of this paragraph (d), no person guilty of fraudulent
     misrepresentation (within the meaning of Section 11(f) of the Act) shall be
     entitled to contribution from any person who was not guilty of such
     fraudulent misrepresentation. For purposes of this Section 6, each person
     who controls a Holder within the meaning of either the Act or the Exchange
     Act and each director, officer, employee and agent of such Holder shall
     have the
<PAGE>
 
                                                                              19

     same rights to contribution as such Holder, and each person who controls
     the Company within the meaning of either the Act or the Exchange Act, each
     officer of the Company who shall have signed the Registration Statement and
     each director of the Company shall have the same rights to contribution as
     the Company, subject in each case to the applicable terms and conditions of
     this paragraph (d).

           (e)  The provisions of this Section 6 will remain in full force and
     effect, regardless of any investigation made by or on behalf of any Holder
     or the Company or any of the officers, directors or controlling persons
     referred to in Section 6 hereof, and will survive the sale by a Holder of
     securities covered by a Registration Statement.

           7.   Underwritten Offerings.  No Holder may participate in any
                ----------------------                                   
underwritten Shelf Registration Statement hereunder unless such Holder (i)
agrees to sell such Holder's Securities on the basis provided in any
underwriting arrangements entered into in connection therewith and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

           8.   Miscellaneous.
                ------------- 

           (a)  No Inconsistent Agreements.  The Company has not, as of the date
                --------------------------                                      
     hereof, entered into, nor shall it, on or after the date hereof, enter
     into, any agreement with respect to its securities that is inconsistent
     with the rights granted to the Holders herein or otherwise conflicts with
     the provisions hereof.

           (b)  Amendments and Waivers.  The provisions of this Agreement, 
                ----------------------
     including the provisions of this sentence, may not be amended, qualified,
     modified or supplemented, and waivers or consents to departures from the
     provisions hereof may not be given, unless the Company has obtained the
     written consent of the Holders of at least a majority of the then
     outstanding aggregate principal amount of Securities (or, after the
     consummation of any Exchange Offer in accordance with Section 2 hereof, of
     Securities and New Securities); provided that, with respect to any matter
                                     --------
     that directly or indirectly affects the rights of any Purchaser hereunder,
     the Company shall obtain the written consent of each such Purchaser against
     which such amendment, qualification, supplement, waiver or consent is to be
     effective. Notwithstanding the foregoing (except the foregoing proviso), a
     waiver or consent to departure from
<PAGE>
 
                                                                              20

     the provisions hereof with respect to a matter that relates exclusively to
     the rights of Holders whose securities are being sold pursuant to a
     Registration Statement and that does not directly or indirectly affect the
     rights of other Holders may be given by the Majority Holders, determined on
     the basis of securities being sold rather than registered under such
     Registration Statement.

           (c)  Notices.  All notices and other communications provided for or
                -------

           holder to the Company in accordance with the provisions of this
           Section 7(c), which address initially is, with respect to each
           Holder, the address of such Holder maintained by the Registrar under
           the Indenture, with a copy in like manner to Salomon Brothers Inc;

                (2)  if to you, initially at the respective addresses set forth
           in the Purchase Agreement; and

           All such notices and communications shall be deemed to have been duly
     given at the time delivered by hand, if personally delivered, five business
     days after being deposited in the mail, postage prepaid, if mailed; when
     answered back, if telexed; when receipt acknowledged, if telecopied; and on
     the next business day, if timely delivered to an air courier guaranteeing
     overnight delivery.

           The Purchasers or the Company by notice to the other may designate
     additional or different addresses for subsequent notices or communications.

           (d)  Successors and Assigns.  This Agreement shall inure to the 
                ----------------------
     benefit of and be binding upon the successors and assigns of each of the
     parties, including, without the need for an express assignment or any
     consent by the Company thereto, subsequent Holders of Securities and/or New

     Agreement to any Holder of Securities and/or New Securities and any such

                  [FORM OF OFFERING MEMORANDUM DESCRIPTION OF
                            REGISTRATION AGREEMENT]



                      EXCHANGE OFFER; REGISTRATION RIGHTS



          The Company and the Initial Purchasers will enter into the
Registration Agreement on or prior to the Closing Date.  The Company will agree,
pursuant to the Registration Agreement with the Initial Purchasers, for the
benefit of the holders, that the Company will, at its cost, (i) no later than 60
days after the Closing Date file the Exchange Offer Registration Statement with
the Commission relating to the Registered Exchange Offer to exchange the Notes
for Exchange Notes having terms substantially identical in all material respects
to the Notes (except that the Exchange Notes will not contain terms with respect
to transfer restrictions) and (ii) use its best efforts to cause the Exchange
Offer Registration Statement to be declared effective under the Securities Act
not later than 150 days after the Closing Date. Upon the effectiveness of the
Exchange Offer Registration Statement, the Company will offer the Exchange Notes
in exchange for surrender of the Notes.  The Company will keep the Registered
Exchange Offer open for not less than 30 days and not more than 45 days (or
longer if required by applicable law) after the date notice of the Registered
Exchange Offer is mailed to the holders. For each Note surrendered to the
Company pursuant to the Registered Exchange Offer, the holder of such Note will
receive an Exchange Note having a principal amount equal to that of the
surrendered Note.  Interest on each Exchange Note will accrue from the last
Interest Payment Date on which interest was paid on the Note surrendered in
exchange therefor, or, if no interest has been paid on such Note, from the date
of its original issue. Under existing Commission interpretations, the Exchange
Notes would be freely transferable by holders other than affiliates of the
Company after the Registered Exchange Offer without further registration under
the Securities Act if the holder of the Exchange Notes represents that it is
acquiring the Exchange Notes in the ordinary course of its business, that it has
no arrangement or understanding with any person to participate in the
distribution of the Exchange Notes and that it is not an affiliate of the
Company, as such terms are interpreted by the Commission; provided that broker-
dealers ("Participating Broker-Dealers") receiving Exchange Notes in the
Registered Exchange Offer will have a prospectus delivery requirement with
respect to

                                                                               2

resales of such Exchange Notes.  The Commission has taken the position that
Participating Broker-Dealers may fulfill their prospectus delivery requirements
with respect to Exchange Notes (other than a resale of an unsold allotment from
the original sale of the Notes) with the prospectus contained in the Exchange
Offer Registration Statement.  Under the Registration Agreement, the Company is
required to allow Participating Broker-Dealers and other persons, if any, with
similar prospectus delivery requirements to use the prospectus contained in the
Exchange Offer Registration Statement in connection with the resale of such
Exchange Notes.

          A holder of Notes (other than certain specified holders) who wishes to
exchange such Notes for Exchange Notes in the Registered Exchange Offer will be
required to represent that any Exchange Notes to be received by it will be
acquired in the ordinary course of its business, and that at the time of the
commencement of the Registered Exchange Offer it has no arrangement or
understanding with any person to participate in the distribution (within the
meaning of the Securities Act) of the Exchange Notes and that it is not an
"affiliate" of the Company, as defined in Rule 405 of the Securities Act, or if
it is an affiliate, that it will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable.

          In the event that applicable interpretations of the staff of the
Commission do not permit the Company to effect such a Registered Exchange Offer,
or if for any other reason the Registered Exchange Offer is not consummated
within 180 days after the Closing Date, or if the Initial Purchasers so request
with respect to Notes not eligible to be exchanged for Exchange Notes in the
Registered Exchange Offer, or if any holder of Notes does not receive freely
tradeable Exchange Notes in the Registered Exchange Offer, the Company will, at
its cost, (a) as promptly as practicable, file a Shelf Registration Statement
covering resales of the Notes or the Exchange Notes, as the case may be, (b) use
its best efforts to cause the Shelf Registration Statement to be declared
effective under the Securities Act and (c) keep the Shelf Registration Statement
effective until two years after its effective date or such shorter period ending
when all resales of Notes or Exchange Notes covered by such Shelf Registration
Statement have been made.  The Company will, in the event a Shelf Registration
Statement is filed, among other things, provide to each holder for whom such
Shelf Registration Statement was filed copies of the prospectus which is a part
of the Shelf Registration Statement, notify each such holder when the Shelf
Registration Statement has become effective and take certain other actions as
are required to permit unrestricted

                                                                               3

resales of the Notes or the Exchange Notes, as the case may be. A holder selling
such Notes or Exchange Notes pursuant to the Shelf Registration Statement
generally would be required to be named as a selling security holder in the
related prospectus and to deliver a prospectus to purchasers, will be subject to
certain of the civil liability provisions under the Securities Act in connection
with such sales and will be bound by the provisions of the Registration
Agreement which are applicable to such holder (including certain indemnification
obligations).

          If (i) within 60 days after the Closing Date, neither the Exchange
Offer Registration Statement nor the Shelf Registration Statement has been filed
with the Commission; (ii) within 150 days after the Closing Date the Exchange
Offer Registration Statement has not been declared effective; (iii) within 180
days after the Closing Date, neither the Registered Exchange Offer has been
consummated nor the Shelf Registration Statement has been declared effective; or
(iv) after either the Exchange Offer Registration Statement or the Shelf
Registration Statement has been declared effective, such Registration Statement
thereafter ceases to be effective or usable (subject to certain exceptions) in
connection with resales of Notes or Exchange Notes in accordance with and during
the periods specified in the Registration Agreement, Special Interest will
accrue and be payable semi-annually on the Notes and the Exchange Notes (in
addition to the stated interest on the Notes and the Exchange Notes) from and
including the date on which any such Registration Default shall occur to but
excluding the date on which all Registration Defaults have been cured.  Special
Interest will accrue and be payable semi-annually at a rate of 0.50% per annum
during the 90-day period immediately following the occurrence of any
Registration Default and shall increase by 0.25% per annum at the end of each
subsequent 90-day period, but in no event shall such rate exceed 2.00% per annum
in the aggregate regardless of the number of Registration Defaults.

          The summary herein of certain provisions of the Registration Agreement
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, all the provisions of the Registration Agreement, a
copy of which is available upon request to the Company.

Each broker-dealer that receives New Securities for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Securities.  The Letter of Transmittal
states that by so acknowledging and by delivering a prospectus, a broker-dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act.  This Prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of New
Securities received in exchange for Securities where such New Securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities.  The Company has agreed that, starting on the Expiration
Date (as defined herein) and ending on the close of business on the first
anniversary of the Expiration Date, it will make this Prospectus available to
any broker-dealer for use in connection with any such resale.  See "Plan of
Distribution."

Each broker-dealer that receives New Securities for its own account in exchange
for Securities, where such Securities were acquired by such broker-dealer as a
result of market-making activities or other trading activities, must acknowledge
that it will deliver a prospectus in connection with any resale of such New
Securities.  See "Plan of Distribution."

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

     Each broker-dealer that receives New Securities for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Securities.  This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of New Securities received in
exchange for Securities where such Securities were acquired as a result of
market-making activities or other trading activities.  The Company has agreed
that, starting on the Expiration Date and ending on the close of business on the
first anniversary of the Expiration Date, it will make this Prospectus, as
amended or supplemented, available to any broker-dealer for use in connection
with any such resale.

          The Company will not receive any proceeds from any sale of New
Securities by broker-dealers.  New Securities received by broker-dealers for
their own account pursuant to the Exchange Offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the New Securities or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices.  Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer and/or the purchasers of any such New
Securities.  Any broker-dealer that resells New Securities that were received by
it for its own account pursuant to the Exchange Offer and any broker or dealer
that participates in a distribution of such New Securities may be deemed to be
an "underwriter" within the meaning of the Securities Act and any profit of any
such resale of New Securities and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act.  The Letter of Transmittal states that by acknowledging that it will
deliver and by delivering a prospectus, a broker-dealer will not be deemed to
admit that it is an "underwriter" within the meaning of the Securities Act.

          For a period of 1 year after the Expiration Date, the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company has agreed to pay all expenses
incident to the Exchange Offer (including the expenses of one counsel for the
<PAGE>
 
holders of the Securities) other than commissions or concessions of any brokers
or dealers and will indemnify the holders of the Securities (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.

and/or 508.]

If the undersigned is not a broker-dealer, the undersigned represents that it is
not engaged in, and does not intend to engage in, a distribution of New

the Securities to be exchanged for New Securities were acquired by it as a
result of market-making activities or other trading activities and acknowledges
that it will deliver a prospectus in connection with any resale of such New
Securities; however, by so acknowledging and by delivering a prospectus, the
undersigned will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.
