                             UNDERWRITING AGREEMENT

                                 August 21, 1997

MERRILL LYNCH & CO.

Ladies and Gentlemen:

         United  States  Cellular  Corporation,   a  Delaware  corporation  (the
"Company"),  proposes to issue and sell up to $400,000,000  aggregate  principal
amount of its senior debt securities (the "Debt  Securities") from time to time,
in or pursuant to one or more offerings on terms to be determined at the time of
sale.

         The Debt  Securities  will be  issued  in one or more  series as senior
indebtedness (the "Debt  Securities")  under an indenture,  dated as of July 31,
1997 (the  "Indenture"),  between  the Company  and The First  National  Bank of
Chicago, as trustee (the "Trustee"). Each series of Debt Securities may vary, as
applicable,  as to title,  aggregate  principal amount,  rank,  interest rate or
formula and timing of payments thereof,  stated maturity date, redemption and/or
repayment  provisions,  sinking fund  requirements  and any other variable terms
established by or pursuant to the applicable Indenture.

         Whenever the Company  determines to make an offering of Debt Securities
through Merrill Lynch & Co., Merrill Lynch, Pierce,  Fenner & Smith Incorporated
("Merrill  Lynch"),  or through  an  underwriting  syndicate  managed by Merrill
Lynch,  the Company will enter into an  agreement  (each,  a "Terms  Agreement")
providing for the sale of such Debt Securities to, and the purchase and offering
thereof  by,  Merrill  Lynch and such other  underwriters,  if any,  selected by
Merrill  Lynch (the  "Underwriters",  which term shall  include  Merrill  Lynch,
whether acting as sole Underwriter or as



                                       -1-

<PAGE>



a member of an underwriting  syndicate,  as well as any Underwriter  substituted
pursuant to Section 10 hereof).  The Terms Agreement relating to the offering of
Debt Securities shall specify the aggregate  principal amount of Debt Securities
to be  issued  (the  "Underwritten  Securities"),  the name of each  Underwriter
participating  in such offering  (subject to substitution as provided in Section
10 hereof) and the name of any  Underwriter  other than Merrill  Lynch acting as
co-manager in connection with such offering,  the aggregate  principal amount of
Underwritten   Securities  which  each  such  Underwriter  severally  agrees  to
purchase, whether such offering is on a fixed or variable price basis and, if on
a fixed  price  basis,  the  initial  offering  price,  the  price at which  the
Underwritten Securities are to be purchased by the Underwriters, the form, time,
date and place of delivery and payment of the  Underwritten  Securities  and any
other  material  variable  terms  of  the  Underwritten  Securities.  The  Terms
Agreement,  which shall be  substantially  in the form of Exhibit A hereto,  may
take the form of an exchange of any standard  form of written  telecommunication
between the Company and Merrill Lynch, acting for itself and, if applicable,  as
representative  of  any  other  Underwriters.   Each  offering  of  Underwritten
Securities  through Merrill Lynch as sole Underwriter or through an underwriting
syndicate  managed  by  Merrill  Lynch  will be  governed  by this  Underwriting
Agreement, as supplemented by the applicable Terms Agreement.

         The Company has filed with the Securities and Exchange  Commission (the
"Commission")  a  registration  statement  on Form S-3 (No.  333-32521)  for the
registration of the Debt Securities under the Securities Act of 1933, as amended
(the "1933 Act"),  and the offering thereof from time to time in accordance with
Rule 415 of the rules and regulations of the Commission  under the 1933 Act (the
"1933 Act Regulations"). Such registration statement has been declared effective
by the  Commission  and the  Indenture has been duly  qualified  under the Trust
Indenture  Act of 1939,  as amended (the "1939 Act"),  and the Company has filed
such post-effective amendments thereto as may be required prior to the execution
of the applicable  Terms  Agreement and each such  post-effective  amendment has
been declared  effective by the Commission.  Such registration  statement (as so
amended, if applicable),  including the information, if any, deemed to be a part
thereof  pursuant to Rule  430A(b) of the 1933 Act  Regulations  (the "Rule 430A
Information")  or Rule  434(d)  of the  1933  Act  Regulations  (the  "Rule  434
Information"),  is referred to herein as the "Registration  Statement";  and the
final prospectus and the final prospectus supplement relating to the offering of
the Underwritten Securities,  in the form first furnished to the Underwriters by
the  Company  for  use in  connection  with  the  offering  of the  Underwritten
Securities,  are collectively referred to herein as the "Prospectus";  provided,
however,   that  all  references  to  the   "Registration   Statement"  and  the
"Prospectus" shall also be deemed to include all documents  incorporated therein
by reference  pursuant to the  Securities  Exchange Act of 1934, as amended (the
"1934 Act"), prior to the execution of the applicable Terms Agreement; provided,
further, that if the Company files a registration  statement with the Commission
pursuant  to  Rule  462(b)  of  the  1933  Act  Regulations  (the  "Rule  462(b)
Registration   Statement"),   then,   after  such  filing,   all  references  to
"Registration  Statement"  shall  also be  deemed  to  include  the Rule  462(b)
Registration  Statement;  and provided,  further,  that if the Company elects to
rely  upon  Rule  434 of the  1933  Act  Regulations,  then  all  references  to
"Prospectus" shall also be deemed to include the final or preliminary prospectus
and the applicable term sheet or abbreviated  term sheet (the "Term Sheet"),  as
the case may be, in the form first furnished to the  Underwriters by the Company
in reliance upon Rule 434 of the 1933 Act



                                       -2-

<PAGE>



Regulations,  and all references in this  Underwriting  Agreement to the date of
the Prospectus shall mean the date of the Term Sheet. A "preliminary prospectus"
shall  be  deemed  to refer  to any  prospectus  used  before  the  Registration
Statement became effective and any prospectus that omitted,  as applicable,  the
Rule 430A  Information,  the Rule 434  Information  or other  information  to be
included upon pricing in a form of prospectus filed with the Commission pursuant
to Rule 424(b) of the 1933 Act Regulations and was used after such effectiveness
and prior to the execution and delivery of the applicable Terms  Agreement.  For
purposes of this  Underwriting  Agreement,  all  references to the  Registration
Statement,  Prospectus, Term Sheet or preliminary prospectus or to any amendment
or supplement to any of the foregoing  shall be deemed to include any copy filed
with the Commission  pursuant to its  Electronic  Data  Gathering,  Analysis and
Retrieval system ("EDGAR").

         All references in this Underwriting  Agreement to financial  statements
and schedules and other information which is "contained," "included" or "stated"
(or other references of like import) in the Registration  Statement,  Prospectus
or preliminary prospectus shall be deemed to mean and include all such financial
statements  and  schedules  and  other  information  which  is  incorporated  by
reference in the Registration  Statement,  Prospectus or preliminary prospectus,
as the case may be, prior to the execution of the  applicable  Terms  Agreement;
and all references in this  Underwriting  Agreement to amendments or supplements
to the  Registration  Statement,  Prospectus or preliminary  prospectus shall be
deemed to mean and include the filing of any  document  under the 1934 Act which
is  incorporated  by  reference in the  Registration  Statement,  Prospectus  or
preliminary  prospectus,  as  the  case  may  be,  after  the  execution  of the
applicable Terms Agreement.

         SECTION 1.          Representations and Warranties.

         (a) The Company  represents  and warrants to Merrill  Lynch,  as of the
date hereof, and to each Underwriter named in the applicable Terms Agreement, as
of the date  thereof,  and as of the Closing  Time (as  defined  below) (in each
case, a "Representation Date") as follows:

                  (i) The  Company  meets the  requirements  for use of Form S-3
         under the 1933 Act.  The  Registration  Statement  (including  any Rule
         462(b) Registration  Statement) has become effective under the 1933 Act
         and no stop order  suspending  the  effectiveness  of the  Registration
         Statement (or such Rule 462(b) Registration  Statement) has been issued
         under  the  1933 Act and no  proceedings  for that  purpose  have  been
         instituted  or are pending or, to the  knowledge  of the  Company,  are
         contemplated  by the  Commission,  and any  request  on the part of the
         Commission  for  additional  information  has been  complied  with.  In
         addition, the Indenture has been duly qualified under the 1939 Act.

                  At the respective times the Registration  Statement (including
         any  Rule  462(b)   Registration   Statement)  and  any  post-effective
         amendments  thereto  (including the filing of the Company's most recent
         Annual Report on Form 10-K with the  Commission  (the "Annual Report on
         Form 10-K"))  became  effective and at each  Representation  Date,  the
         Registration   Statement   (including  any  Rule  462(b)   Registration
         Statement) and any amendments thereto



                                       -3-

<PAGE>



         complied and will comply in all material respects with the requirements
         of the 1933 Act and the 1933 Act  Regulations  and the 1939 Act and the
         rules and  regulations of the Commission  under the 1939 Act (the "1939
         Act  Regulations") and did not and will not 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.  At the date of the  Prospectus  and at the  Closing  Time,
         neither the  Prospectus  nor any  amendments  and  supplements  thereto
         included  or will  include an untrue  statement  of a material  fact or
         omitted or will omit to state a  material  fact  necessary  in order to
         make the statements  therein,  in the light of the circumstances  under
         which they were made,  not  misleading.  If the Company  elects to rely
         upon Rule 434 of the 1933 Act Regulations, the Company will comply with
         the requirements of Rule 434.

                  Each  preliminary  prospectus and prospectus  filed as part of
         the  Registration  Statement  as  originally  filed  or as  part of any
         amendment  thereto,  or filed  pursuant to Rule 424 under the 1933 Act,
         complied  when so  filed  in all  material  respects  with the 1933 Act
         Regulations  and  each   preliminary   prospectus  and  the  Prospectus
         delivered to the  Underwriters  for use in connection with the offering
         of  Underwritten  Securities  will,  at the time of such  delivery,  be
         identical to any  electronically  transmitted copies thereof filed with
         the  Commission  pursuant to EDGAR,  except to the extent  permitted by
         Regulation S-T.  Notwithstanding the foregoing, the representations and
         warranties  in this  subsection  shall  not apply to  statements  in or
         omissions from the  Registration  Statement or the  Prospectus  made in
         reliance  upon and in  conformity  with  information  furnished  to the
         Company in writing by any  Underwriter  through Merrill Lynch expressly
         for use in the Registration Statement or the Prospectus.

                  (ii) The documents  incorporated  or deemed to be incorporated
         by reference in the Registration  Statement and the Prospectus,  at the
         time they were or hereafter are filed with the Commission, complied and
         will comply in all material  respects with the requirements of the 1934
         Act and the rules and  regulations  of the Commission  thereunder  (the
         "1934  Act  Regulations")  and,  when  read  together  with  the  other
         information in the Prospectus, at the date of the Prospectus and at the
         Closing  Time did not and will not  include  an untrue  statement  of a
         material  fact or omit to state a material  fact  necessary in order to
         make the statements  therein,  in the light of the circumstances  under
         which they were made, not misleading.

                  (iii) The accountants who certified the Company's consolidated
         financial   statements   and  supporting   schedules   included  in  or
         incorporated  by  reference  into the  Registration  Statement  and the
         Prospectus  are  independent  public  accountants  with  respect to the
         Company and its  consolidated  subsidiaries as required by the 1933 Act
         and the 1933 Act Regulations.

                  (iv)     The consolidated financial statements of the Company 
         and its subsidiaries included in the Registration Statement and the 
         Prospectus present fairly the financial position



                                       -4-

<PAGE>



         and results of  operations  of the Company  and its  subsidiaries  on a
         consolidated  basis  at the  respective  dates  or for  the  respective
         periods  to which  they  apply;  such  financial  statements  have been
         prepared in accordance with generally  accepted  accounting  principles
         applied  on  a  consistent  basis  throughout  the  respective  periods
         involved and such  financial  statements  have been  prepared,  and the
         combined   financial   statements  of  the  Los  Angeles  SMSA  Limited
         Partnership,  the Nashville/Clarksville MSA Limited Partnership and the
         Baton Rouge MSA Limited Partnership (collectively, the "Cellular System
         Partnerships")   included  in  the   Registration   Statement  and  the
         Prospectus  have been  properly  compiled from the amounts and notes of
         the underlying  separate audited  financial  statements of the Cellular
         System  Partnerships,  in each case in compliance  with the  applicable
         accounting requirements of the 1933 Act and the 1933 Act Regulations or
         the 1934 Act and the 1934 Act Regulations,  as the case may be; and the
         supporting  schedules  included in the Registration  Statement  present
         fairly the  information  required to be stated  therein.  The  selected
         financial data and the summary  financial  information  included in the
         Prospectus  present fairly the information  shown therein and have been
         compiled  on a basis  consistent  with  that of the  audited  financial
         statements  included in the Registration  Statement and the Prospectus.
         In addition,  any pro forma financial statements of the Company and its
         subsidiaries and the related notes thereto included in the Registration
         Statement  and the  Prospectus  present  fairly the  information  shown
         therein,  have been prepared in accordance with the Commission's  rules
         and guidelines with respect to pro forma financial  statements and have
         been  properly  compiled  on  the  bases  described  therein,  and  the
         assumptions  used in the  preparation  thereof are  reasonable  and the
         adjustments  used  therein  are  appropriate  to  give  effect  to  the
         transactions and circumstances referred to therein.

                  (v)  Since the  respective  dates as of which  information  is
         given in the  Registration  Statement  and the  Prospectus,  except  as
         otherwise stated therein, (A) there has been no material adverse change
         in the condition,  financial or otherwise, or in the earnings, business
         affairs or  business  prospects  of the  Company  and its  consolidated
         subsidiaries  considered as one  enterprise,  whether or not arising in
         the ordinary  course of business,  (B) there have been no  transactions
         entered  into by the  Company or any of its  consolidated  subsidiaries
         other than those in the ordinary  course of business which are material
         to the  Company and its  consolidated  subsidiaries  considered  as one
         enterprise,  and (C) there has been no dividend or  distribution of any
         kind declared,  paid or made by the Company on any class of its capital
         stock.

                  (vi) The  Company  has been duly  incorporated  and is validly
         existing as a corporation  in good standing under the laws of the State
         of Delaware,  and has corporate  power and authority to own,  lease and
         operate its  properties and to conduct its business as described in the
         Prospectus and to enter into and perform its  obligations  under, or as
         contemplated  under,  this  Underwriting  Agreement and the  applicable
         Terms Agreement. The Company is duly qualified as a foreign corporation
         to transact  business and is in good standing in each  jurisdiction  in
         which it owns or leases substantial  properties or in which the conduct
         of its business requires such  qualification,  except where the failure
         to be so qualified



                                       -5-

<PAGE>



         or in good  standing  would not have a material  adverse  affect on the
         Company and its consolidated subsidiaries considered as one enterprise.

                  (vii) Each  consolidated  subsidiary  of the  Company has been
         duly  incorporated  and is validly  existing as a  corporation  in good
         standing under the laws of the jurisdiction of its  incorporation,  has
         the  corporate  power  and  authority  to own,  lease and  operate  its

         unfavorable decision,  ruling or finding,  would result in any material

         incorporated  by reference  therein,  none of the Company or any of its
         consolidated  subsidiaries  has  received  any  notice  of  proceedings
         relating to the  revocation or  modification  of any such  certificate,
         authority,  license or permit which, singly or in the aggregate, if the
         subject  of  any  unfavorable  decision,   ruling  or  finding,   would
         materially and adversely affect the condition,  financial or otherwise,
         or the earnings,  business affairs or business prospects of the Company

         its  consolidated  subsidiaries  and good title to all other properties
         owned by them that are  material to the business of the Company and its

         sublease.

                  (xix) The  Underwritten  Securities being sold pursuant to the
         applicable Terms Agreement, upon issuance, will be excluded or exempted
         under, or beyond the purview of, the Commodity Exchange Act, as amended

         Underwritten  Securities as herein  contemplated and the application of
         the net proceeds  therefrom as described in the Prospectus will not be,

representation and warranty by the Company to each Underwriter as to the matters
covered thereby on the date of such certificate and, unless subsequently amended
or supplemented, at each Representation Date subsequent thereto.

         SECTION 2.        Sale and Delivery to the Underwriters; Closing.

         (a)  The  several  commitments  of the  Underwriters  to  purchase  the

agreements  herein  contained  and shall be subject to the terms and  conditions
herein set forth.

         (b) Payment of the purchase price for the Underwritten Securities shall
be made at the  office  of  Merrill  Lynch & Co.,  5500  Sears  Tower,  Chicago,
Illinois 60606, and delivery of the certificates for the Underwritten Securities
shall be made against payment  therefor at the office of Merrill Lynch,  Pierce,

authorized  Merrill Lynch, for its account,  to accept delivery of, receipt for,
and make payment of the purchase price for, the Underwritten Securities which it
has  severally  agreed  to  purchase.  Merrill  Lynch,  individually  and not as
representative  of the  Underwriters,  may (but shall not be obligated  to) make
payment of the purchase price for the Underwritten Securities to be purchased by
any Underwriter  whose funds have not been received by the Closing Time but such
payment shall not relieve such Underwriter from its obligations hereunder.

         (a) The  Company,  subject  to  Section  3(b),  will  comply  with  the
requirements  of Rule 430A of the 1933 Act  Regulations  and/or  Rule 434 of the
1933   Act   Regulations,   if  and  as   applicable,   and  will   notify   the
representative(s)  of the  Underwriters  immediately,  and confirm the notice in
writing,  of (i)  the  effectiveness  of  any  post-effective  amendment  to the
Registration  Statement  or the filing of any  supplement  or  amendment  to the
Prospectus,  (ii) the receipt of any  comments  from the  Commission,  (iii) any
request by the Commission for any amendment to the Registration Statement or any
amendment or supplement to the  Prospectus or for  additional  information,  and
(iv)  the  issuance  by  the  Commission  of  any  stop  order   suspending  the
effectiveness  of the  Registration  Statement  or of any  order  preventing  or
suspending the use of any  preliminary  prospectus,  or of the suspension of the
qualification  of the  Underwritten  Securities  for  offering  or  sale  in any
jurisdiction,  or of the initiation or threatening of any proceedings for any of
such purposes.  The Company will promptly effect the filings necessary  pursuant
to Rule 424 and will take such steps as it deems necessary to ascertain promptly
whether the  Prospectus  transmitted  for filing under Rule 424 was received for
filing by the  Commission  and, in the event that it was not,  it will  promptly
file the Prospectus.  The Company will make every  reasonable  effort to prevent
the  issuance of any stop order and, if any stop order is issued,  to obtain the
lifting thereof at the earliest possible moment.

         (b) The Company will give Merrill Lynch notice of its intention to file
or prepare any amendment to the  Registration  Statement  (including  any filing
under Rule 462(b) of the 1933 Act Regulations), any Term Sheet or any amendment,
supplement  or revision to either the  prospectus  included in the  Registration
Statement at the time it became effective or to the Prospectus, whether pursuant
to the 1933 Act,  the 1934 Act or  otherwise,  will furnish  Merrill  Lynch with
copies of any such documents a reasonable  amount of time prior to such proposed
filing or use, as the case may be, and will not file or use any such document to
which Merrill Lynch or counsel for the Underwriters shall reasonably object.

         (c)      The Company has furnished or will deliver to Merrill Lynch and
counsel for the Underwriters, without charge, as many signed copies of the 
Registration Statement as originally filed and of each amendment thereto 
(including exhibits filed therewith or incorporated by reference therein and 
documents incorporated or deemed to be incorporated by reference therein) as 
Merrill Lynch has requested or shall reasonably request, and as many signed 
copies of all consents and certificates of experts as Merrill Lynch has 
requested or shall reasonably request, and will also deliver to Merrill Lynch, \
without charge, a conformed copy of the Registration Statement as originally 
filed and of each amendment thereto (without exhibits) for each of the 
Underwriters.  The



                                      -11-

<PAGE>



Registration  Statement and each amendment thereto furnished to the Underwriters
will be identical to any  electronically  transmitted  copies thereof filed with
the Commission  pursuant to EDGAR,  except to the extent permitted by Regulation
S-T.

         (d) The Company will deliver to each  Underwriter,  without charge,  as
many copies of each  preliminary  prospectus as such  Underwriter may reasonably
request,  and the Company hereby consents to the use of such copies for purposes
permitted by the 1933 Act. The Company will furnish to each Underwriter, without
charge,  during the period when the Prospectus is required to be delivered under
the 1933 Act or the 1934 Act,  such number of copies of the  Prospectus  as such
Underwriter  may  reasonably  request.  The  Prospectus  and any  amendments  or
supplements  thereto  furnished  to the  Underwriters  will be  identical to any
electronically  transmitted copies thereof filed with the Commission pursuant to
EDGAR, except to the extent permitted by Regulation S-T.

         (e) The  Company  will  comply  with  the  1933  Act and the  1933  Act
Regulations  and the 1934 Act and the 1934 Act  Regulations  so as to permit the
completion of the distribution of the Underwritten Securities as contemplated in
this  Underwriting  Agreement  and the  applicable  Terms  Agreement  and in the
Registration Statement and the Prospectus. If at any time when the Prospectus is
required  by the 1933 Act or the 1934 Act to be  delivered  in  connection  with
sales of the  Securities,  any event shall occur or  condition  shall exist as a
result of which it is necessary,  in the opinion of counsel for the Underwriters
or for the  Company,  to amend  the  Registration  Statement  in order  that the
Registration  Statement will not 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  or to amend  or  supplement  the
Prospectus in order that the Prospectus will not include an untrue  statement of
a material fact or omit to state a material fact  necessary in order to make the
statements therein not misleading in the light of the circumstances  existing at
the time it is  delivered to a purchaser,  or if it shall be  necessary,  in the
opinion of such counsel, at any such time to amend the Registration Statement or
amend or supplement the Prospectus in order to comply with the  requirements  of
the 1933 Act or the 1933 Act Regulations,  the Company will promptly prepare and
file with the Commission,  subject to Section 3(b), such amendment or supplement
as may be  necessary  to  correct  such  statement  or  omission  or to make the
Registration Statement or the Prospectus comply with such requirements,  and the
Company will furnish to the Underwriters,  without charge, such number of copies
of such amendment or supplement as the Underwriters may reasonably request.

         (f) The Company  will use its best  efforts,  in  cooperation  with the

                           (xix) The Company is not,  and upon the  issuance and
                  sale of the Underwritten Securities as herein contemplated and
                  the application of the net proceeds  therefrom as described in
                  the Prospectus will not be, an "investment company" within the
                  meaning of the Investment Company Act of 1940, as amended (the
                  "1940 Act").

                           (xx)  To  such  counsel's  knowledge,  there  are  no
                  statutes or  regulations  that are required to be described in
                  the Prospectus that are not described as required.

                           (xxi)  To  such  counsel's  knowledge,   neither  the
                  Company nor any of the Direct  Subsidiaries is in violation of
                  its charter or by-laws and no default by the Company or any of
                  its consolidated subsidiaries exists in the due performance or
                  observance of any material obligation,  agreement, covenant or
                  condition contained in any contract, indenture, mortgage, loan
                  agreement,  note,  lease or other agreement or instrument that
                  is described or referred to in the  Registration  Statement or
                  the  Prospectus  or filed or  incorporated  by reference as an
                  exhibit to the Registration Statement.

         Such opinion of Sidley & Austin shall  additionally  state that nothing
has  come  to  their  attention  that  has  caused  them  to  believe  that  the
Registration Statement (including any Rule 426(b) Registration Statement) or any
post-effective  amendment  thereto (except for financial  statements,  including
notes  thereto,  and  supporting  schedules  and other  financial  data included
therein or omitted therefrom and for the Form T-1, as to which no belief need be
expressed),  at the time the Registration  Statement  (including any Rule 462(b)
Registration  Statement) or any post-effective  amendment thereto (including the
filing of the Company's  Annual Report on Form 10-K with the Commission)  became
effective or at the date of the applicable Terms Agreement,  contained an untrue
statement of a material  fact or omitted to state a material fact required to be
stated  therein or necessary to make the  statements  therein not  misleading or
that the Prospectus or any amendment or supplement thereto (except for financial
statements, including notes thereto, and supporting



                                      -18-

<PAGE>



schedules and other financial data included therein or omitted therefrom,  as to
which no belief need be expressed),  at the time the  Prospectus was issued,  at
the time any such  amended  or  supplemented  prospectus  was  issued  or at the
Closing  Time,  included or includes an untrue  statement of a material  fact or
omitted  or  omits  to  state a  material  fact  necessary  in order to make the
statements  therein,  in the light of the  circumstances  under  which they were
made,  not  misleading.  Such counsel may also state that they have relied as to
materiality,  to the  extent  they deem  appropriate  in  accordance  with their
professional responsibilities, upon the judgment of officers and representatives
of the Company.

         Such opinion shall be limited to the laws of the State of New York, the
State of Illinois,  the General Corporation Law of the State of Delaware and the
federal law of the United States (other than the  Communications Act of 1934, as
amended (the "Communications  Act"), and the rules and regulations  thereunder).
In rendering such opinion,  such counsel may rely, as to matters governed by the
Communications Act and the rules and regulations  thereunder upon the opinion of
Koteen and Naftalin delivered to the Underwriters  pursuant to subsection (b)(2)
of this  Section.  Such  counsel  may also state that,  insofar as such  opinion
involves factual matters, they have relied, to the extent they deem proper, upon
certificates of officers of the Company and its subsidiaries and certificates of
public officials.

                  (2) The  opinion,  dated as of  Closing  Time,  of Koteen  and
         Naftalin,  special  counsel  to the  Company,  in  form  and  substance
         reasonably satisfactory to counsel for the Underwriters,  to the effect
         that:

                           (i)  No  filing  with,  or  authorization,  approval,
                  consent, license, order, registration, qualification or decree
                  of, the Federal  Communications  Commission  (the  "FCC"),  is
                  necessary or required for the due authorization,  execution or
                  delivery by the Company of this Underwriting  Agreement or the
                  applicable  Terms  Agreement  or for  the  performance  by the
                  Company of the transactions contemplated under the Prospectus,
                  this  Underwriting  Agreement,  such  Terms  Agreement  or the
                  Indenture.

                           (ii) The execution and delivery of this  Underwriting
                  Agreement,  the applicable  Terms Agreement and the Indenture,
                  the issuance of the Underwritten Securities, the compliance by
                  the Company  with all of the  provisions  of the  Underwritten
                  Securities, the Indenture, this Underwriting Agreement and the
                  applicable   Terms  Agreement  and  the  consummation  of  the
                  transactions   contemplated   herein,   therein   and  in  the
                  Registration  Statement  and  the  Prospectus  (including  the
                  issuance and sale of the Underwritten  Securities as described
                  under the caption "Use of  Proceeds")  do not and will not, to
                  such  counsel's  knowledge,  conflict  with or  result  in any
                  violation  of,  or  the  creation  of  any  lien,   charge  or
                  encumbrance upon, the property or assets of the Company or, to
                  such counsel's knowledge, its consolidated subsidiaries, under
                  the  Communications  Act or any  rule,  regulation,  judgment,
                  order or  administrative  or court decree  issued,  enacted or
                  promulgated thereunder;  neither will any such action conflict
                  with  or  have  a  material  adverse  effect  on  any  of  the
                  certificates, authorities, licenses or permits, if any, issued
                  or to



                                      -19-

<PAGE>



                  be issued  by the FCC to the  Company  or,  to such  counsel's
                  knowledge, any of the Company's consolidated subsidiaries that
                  enable  them to  carry  on the  business  and  operations  now
                  operated by them and which are material to the business of the
                  Company and its  consolidated  subsidiaries  considered as one
                  enterprise.

                           (iii) The information in the  Registration  Statement
                  (or any  post-effective  amendment  thereto) or the Prospectus
                  purporting   to  describe  FCC   regulatory   matters  or  the
                  Communications  Act, to the extent that it constitutes matters
                  of law, summaries of legal matters or legal  conclusions,  has
                  been  reviewed by such  counsel and is correct in all material
                  respects.

         Such  opinion  of Koteen and  Naftalin  shall  additionally  state that
nothing has come to their  attention  that has caused  them to believe  that the
descriptions of FCC regulatory  matters and the  Communications Act contained in
the Registration Statement (including any Rule 426(b) Registration Statement) or
any post-effective amendment thereto (except for financial statements, including
notes thereto,  and supporting  schedules included therein or omitted therefrom,
as to which no belief need be expressed), at the time the Registration Statement
(including  any  Rule  462(b)  Registration  Statement)  or  any  post-effective
amendment  thereto  (including the filing of the Company's Annual Report on Form
10-K with the  Commission)  became  effective  or at the date of the  applicable
Terms Agreement,  contained an untrue statement of a material fact or omitted to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein not  misleading or that the  descriptions  of FCC regulatory
matters and the  Communications Act contained in the Prospectus or any amendment
or supplement thereto (except for financial  statements including notes thereto,
and supporting  schedules included therein or omitted therefrom,  as to which no
belief need be expressed),  at the time the  Prospectus was issued,  at the time
any such amended or  supplemented  prospectus was issued or at the Closing Time,
included or includes an untrue  statement of a material fact or omitted or omits
to state a material fact necessary in order to make the statements  therein,  in
the light of the circumstances under which they were made, not misleading.

                  (3) The opinion,  dated as of Closing Time, of Mayer,  Brown &
         Platt, counsel for the Underwriters, together with signed or reproduced
         copies of such letter for each of the other Underwriters,  with respect
         to the matters set forth in (i) (insofar as it relates to the existence
         and good standing of the Company),  (ii), (v), (vi), (viii), (ix), (x),
         (xii)  (solely  as  to  the   information  in  the   Prospectus   under
         "Description of Debt Securities" or any caption  purporting to describe
         any such Debt  Securities),  (xvii) and the  penultimate  paragraph  of
         subsection (b)(1) of this Section. In giving such opinion, such counsel
         may rely, as to all matters governed by the laws of jurisdictions other
         than the law of the  State of New  York,  the  State of  Illinois,  the
         federal law of the United States and the General Corporation Law of the
         State of Delaware, upon the opinions of counsel satisfactory to Merrill
         Lynch.  Such  counsel  may also state  that,  insofar  as such  opinion
         involves  factual  matters,  they have relied,  to the extent they deem
         proper,   upon   certificates  of  officers  of  the  Company  and  its
         subsidiaries and certificates of public officials.

         (c) At Closing  Time there  shall not have been,  since the date of the
applicable Terms Agreement or since the respective dates as of which information
is given in the  Prospectus,  any  material  adverse  change  in the  condition,
financial  or  otherwise,  or in the  earnings,  business  affairs  or  business
prospects  of the Company and its  subsidiaries  considered  as one  enterprise,
whether or not arising in the  ordinary  course of business,  and Merrill  Lynch
shall  have  received  a  certificate   of  the  Chairman,   President  or  Vice
President-Finance  of the  Company and of the  Controller  or  Treasurer  of the
Company, dated as of Closing Time, to the effect that (i) there has been no such
material  adverse  change  with  respect  to the  Company  and its  subsidiaries
considered as one enterprise, (ii) the representations and warranties in Section
1(a) are true and  correct  with the same force and  effect as though  expressly
made at and as of  Closing  Time,  (iii)  the  Company  has  complied  with  all
agreements and satisfied all conditions on its part to be performed or satisfied
at or prior to Closing Time, and (iv) no stop order suspending the effectiveness
of the  Registration  Statement  has been  received  by the  Company  or, to the
Company's knowledge,  issued and, to the Company's knowledge, no proceedings for
that purpose have been initiated or threatened by the Commission.

         (d) At the time of the  execution of the  applicable  Terms  Agreement,
Merrill Lynch shall have  received from Arthur  Andersen LLP a letter dated such
date, in form and substance  satisfactory to Merrill Lynch, together with signed
or  reproduced  copies  of  such  letter  for  each of the  other  Underwriters,
containing  statements  and  information  of the  type  ordinarily  included  in
accountants'  "comfort  letters" to  underwriters  with respect to the financial
statements  and certain  financial  information  contained  in the  Registration
Statement and the Prospectus.

         (e) At Closing  Time,  Merrill  Lynch shall have  received  from Arthur
Andersen  LLP a  letter,  dated as of  Closing  Time,  to the  effect  that they
reaffirm the statements made in the letter furnished  pursuant to subsection (d)
of this Section,  except that the specified date referred to shall be a date not
more than three business days prior to Closing Time.

         (f) At  Closing  Time  counsel  for the  Underwriters  shall  have been
furnished with such  documents and opinions as they may  reasonably  require for
the  purpose  of  enabling  them to  pass  upon  the  issuance  and  sale of the
Underwritten Securities, as contemplated herein, and related proceedings,  or in
order to evidence the accuracy of any of the  representations or warranties,  or
the fulfillment of any of the conditions,  herein contained; and all proceedings
taken  by  the  Company  in  connection  with  the  issuance  and  sale  of  the
Underwritten  Securities shall be reasonably  satisfactory in form and substance
to Merrill Lynch and counsel for the Underwriters.

         (g) At Closing Time, the Underwritten Securities shall have the ratings
accorded by any "nationally  recognized  statistical  rating  organization",  as
defined  by the  Commission  for  purposes  of Rule  436(g)(2)  of the  1933 Act
Regulations (a "NRSRO"), if and as specified in the applicable Terms Agreement.

         (h) At  Closing  Time,  the  Underwritten  Securities  shall  have been
approved for listing,  subject  only to official  notice of issuance,  if and as
specified in the applicable Terms Agreement.




                                      -21-

         (i)  If the  Registration  Statement  or an  offering  of  Underwritten
Securities  is required  to be and has been filed with the NASD for review,  the
NASD shall not have raised any objection that remains unresolved at Closing Time
with respect to the fairness and  reasonableness  of the underwriting  terms and
arrangements.

         If any  condition  specified  in  this  Section  shall  not  have  been
fulfilled when and as required to be fulfilled,  this Underwriting Agreement and
the applicable  Terms  Agreement may be terminated by Merrill Lynch by notice to
the Company at any time at or prior to Closing Time and such  termination  shall
be without  liability  of any party to any other  party  except as  provided  in
Section  4 and  except  that  Sections  1, 6, 7 and 8  shall  survive  any  such
termination and remain in full force and effect.

         SECTION 6.        Indemnification.

         (a) The Company agrees to indemnify and hold harmless each  Underwriter
and each person,  if any, who  controls  any  Underwriter  within the meaning of
Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

                  (i) against  any and all loss,  liability,  claim,  damage and
         expense whatsoever, as incurred, arising out of any untrue statement or
         alleged   untrue   statement  of  a  material  fact  contained  in  the
         Registration  Statement (or any amendment thereto),  including the Rule
         430A Information and the Rule 434 Information  deemed to be part of the
         Registration  Statement,  if  applicable,  or the  omission  or alleged
         omission  therefrom of a material fact required to be stated therein or
         necessary to make the statements  therein not misleading or arising out
         of any untrue  statement or alleged untrue statement of a material fact
         contained  in any  preliminary  prospectus  or the  Prospectus  (or any
         amendment or  supplement  thereto) or the omission or alleged  omission
         therefrom of a material fact  necessary in order to make the statements
         therein,  in the light of the circumstances under which they were made,
         not misleading;

                  (ii) against any and all loss,  liability,  claim,  damage and
         expense whatsoever,  as incurred, to the extent of the aggregate amount
         paid  in  settlement  of  any  litigation,   or  any  investigation  or
         proceeding by any governmental agency or body, commenced or threatened,
         or any  claim  whatsoever  based  upon any  such  untrue  statement  or
         omission or any such alleged  untrue  statement  or omission;  provided
         that  (subject to Section 6(d) below) any such  settlement  is effected
         with the written consent of the Company; and

                  (iii)  against  any and all  expense  whatsoever,  as incurred
         (including,  subject to Section 6(c) hereof, the fees and disbursements
         of  counsel   chosen  by  Merrill   Lynch),   reasonably   incurred  in
         investigating,  preparing or defending  against any litigation,  or any
         investigation  or  proceeding  by  any  governmental  agency  or  body,
         commenced or threatened,  or any claim  whatsoever  based upon any such
         untrue statement or omission, or any such



                                      -22-

<PAGE>



         alleged untrue statement or omission, to the extent that any such 
         expense is not paid under(i) or (ii) above;

provided, however, that (A) this indemnity agreement does not apply to any loss,
liability,  claim,  damage or expense to the  extent  arising  out of any untrue
statement or omission or alleged  untrue  statement or omission made in reliance
upon and in conformity with written information  furnished to the Company by any
Underwriter  through  Merrill  Lynch  expressly  for  use  in  the  Registration
Statement (or any amendment  thereto),  including the Rule 430A  Information and
the Rule 434  Information  deemed to be a part thereof,  if  applicable,  or any
preliminary  prospectus  or the  Prospectus  (or  any  amendment  or  supplement
thereto)  and (B) this  indemnity  agreement,  with  respect to any  preliminary
prospectus, does not apply to any loss, liability, claim, damage or expense if a
copy of the  Prospectus (as then amended or  supplemented,  if the Company shall
have furnished any amendments or supplements  thereto to an Underwriter) was not
sent or given by or on behalf of such  Underwriter  to the person  asserting any
such loss, liability,  claim, damage or expense if such is required by law at or
prior to the written confirmation of the sale of such Underwritten Securities to
such person and if the Prospectus (as so amended or supplemented) would have, as
determined by a court of competent jurisdiction, cured the defect giving rise to
such loss, liability, claim, damage or expense.

         (b) Each  Underwriter  severally  agrees to indemnify and hold harmless
the Company, each of the Company's directors, each of the Company's officers who
signed the  Registration  Statement,  and each person,  if any, who controls the
Company  within  the  meaning of Section 15 of the 1933 Act or Section 20 of the
1934  Act  against  any and all  loss,  liability,  claim,  damage  and  expense
described in the  indemnity  contained in  subsection  (a) of this  Section,  as
incurred,  but only with respect to untrue  statements or omissions,  or alleged
untrue  statements  or  omissions,  made in the  Registration  Statement (or any
amendment  thereto),  including  the  Rule  430A  Information  and the  Rule 434
Information  deemed to be a part  thereof,  if  applicable,  or any  preliminary
prospectus  or the  Prospectus  (or any  amendment  or  supplement  thereto)  in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company by such  Underwriter  through  Merrill  Lynch  expressly  for use in the
Registration Statement (or any amendment thereto) or such preliminary prospectus
or the Prospectus (or any amendment or supplement thereto).

         (c) Each indemnified  party shall give notice as promptly as reasonably
practicable to each  indemnifying  party of any action  commenced  against it in
respect of which indemnity may be sought hereunder,  but failure to so notify an
indemnifying  party shall not relieve such indemnifying party from any liability
hereunder to the extent it is not materially  prejudiced as a result thereof and
in any event shall not relieve it from any liability which it may have otherwise
than on account of this indemnity agreement.  In case any such action is brought
against any indemnified  party,  and it notifies the  indemnifying  party of the
commencement  thereof,  the  indemnifying  party will be entitled to participate
therein,  and to the extent that it may elect by written notice delivered to the
indemnified  party  promptly  after  receiving  the  aforesaid  notice from such
indemnified  party,  to assume the  defense  thereof,  with  counsel  reasonably
satisfactory  to  such  indemnified  party,  provided,   however,  that  if  the
defendants (including any impleaded defendants) in any such action



                                      -23-

<PAGE>



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, the indemnified
party or parties shall have the right to select separate  counsel.  Upon receipt
of notice from the indemnifying  party to such indemnified party of its election
so to assume the defense of such action and approval by the indemnified party of
counsel,  the indemnifying  party will not be liable to such  indemnified  party
under this Section 6 for any legal fees or other expenses  subsequently incurred
by such  indemnified  party in  connection  with the defense  thereof other than
reasonable  costs of investigation  unless (i) the indemnified  party shall have
employed  separate  counsel in accordance with the proviso to the next preceding
sentence (it being understood,  however,  that the indemnifying party shall not,
in connection  with any one action or separate but similar or related actions in
the  same  jurisdiction   arising  out  of  the  same  general   allegations  or
circumstances,  be liable for the fees and  expenses  of more than one  separate
counsel (plus any local  counsel)  representing  the  indemnified  parties under
Section 6(a) who are parties to such action);  (ii) the indemnifying party shall
not have employed counsel  reasonably  satisfactory to the indemnified  party to
represent  the  indemnified  party  within a  reasonable  time  after  notice of
commencement of the action;  or (iii) the indemnifying  party has authorized the
employment  of  counsel  for  the  indemnified  party  at  the  expense  of  the
indemnifying party; and except that, if clause (i) or (iii) is applicable,  such
liability shall be only in respect of the counsel referred to in such clause (i)
or (iii). No indemnifying party shall,  without the prior written consent of the
indemnified  parties,  settle  or  compromise  or  consent  to the  entry of any
judgment with respect to any litigation,  or any  investigation or proceeding by
any  governmental  agency  or  body,  commenced  or  threatened,  or  any  claim
whatsoever in respect of which  indemnification  or contribution could be sought
under this Section 6 or Section 7 hereof (whether or not the indemnified parties
are actual or potential parties thereto), unless such settlement,  compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

         (d) If at any time an indemnified party shall have requested in writing
an indemnifying  party to reimburse the indemnified  party for fees and expenses
of  counsel,  such  indemnifying  party  agrees  that it shall be liable for any
settlement of the nature  contemplated by Section 6(a)(ii)  effected without its
written consent if (i) such settlement is entered into after the later of (A) 45
days after such  indemnified  party has mailed (by registered or certified mail,
postage  prepaid) the  aforesaid  request to each of the Notice  Recipients  (as
defined below) and (B) if the indemnifying party has not given written notice to
such  indemnified  party  of the  receipt  by  such  indemnifying  party  of the
aforesaid  request,  30  days  after  such  indemnified  party  has  mailed  (by
registered or certified mail,  postage prepaid) a second such request to each of
the Notice Recipients,  provided that such second request is not mailed prior to
the 46th day after the request  referred to in subclause (i)(A) above is mailed,
(ii) such  indemnifying  party shall have  received  notice of the terms of such
settlement  at least 30 days prior to such  settlement  being  entered  into and
(iii) such  indemnifying  party shall not have reimbursed such indemnified party
in  accordance  with  such  request  prior  to  the  date  of  such  settlement.
Notwithstanding  the  immediately   preceding  sentence,   if  at  any  time  an
indemnified party



                                      -24-

<PAGE>



shall have requested an indemnifying  party to reimburse the  indemnified  party
for fees and expenses of counsel,  an indemnifying party shall not be liable for
any settlement of the nature  contemplated by Section 6(a)(ii)  effected without
its consent if such indemnifying  party (i) reimburses such indemnified party in
accordance  with such  request to the  extent it  considers  such  request to be
reasonable  and  (ii)  provides   written  notice  to  the   indemnified   party
substantiating  the unpaid  balance as  unreasonable,  in each case prior to the
date of such settlement.  The Notice Recipients are the Chairman, the President,
the Chief  Financial  Officer  and the  Secretary  of the  Company and the Chief
Financial Officer and the Secretary of Telephone and Data Systems, Inc. ("TDS").
Requests mailed pursuant to this Section 6(d) to (i) the Chairman, the President

States Cellular Corporation,  8410 West Bryn Mawr, Suite 700, Chicago,  Illinois
60631-3486,  (ii) the  Secretary  of the  Company  shall be mailed to Stephen P.

         SECTION 7. Contribution. If the indemnification provided for in Section
6 hereof is for any reason  unavailable to or  insufficient  to hold harmless an
indemnified  party in respect of any  losses,  liabilities,  claims,  damages or
expenses referred to therein,  then each indemnifying  party shall contribute to
the aggregate amount of such losses,  liabilities,  claims, damages and expenses
incurred by such  indemnified  party, as incurred,  (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company, on the one
hand,  and the  Underwriters,  on the  other  hand,  from  the  offering  of the
Underwritten  Securities  pursuant to the applicable  Terms Agreement or (ii) if
the  allocation  provided by clause (i) is not permitted by  applicable  law, in
such  proportion  as is  appropriate  to reflect not only the relative  benefits
referred to in clause (i) above but also the relative  fault of the Company,  on
the one hand, and the  Underwriters,  on the other hand, in connection  with the
statements  or omissions  which  resulted in such losses,  liabilities,  claims,
damages or expenses, as well as any other relevant equitable considerations.

         The relative benefits received by the Company, on the one hand, and the
Underwriters,  on the  other  hand,  in  connection  with  the  offering  of the
Underwritten  Securities  pursuant to the applicable  Terms  Agreement  shall be
deemed to be in the same  respective  proportions as the total net proceeds from
the  offering  of  such  Underwritten  Securities  (before  deducting  expenses)
received  by the  Company and the total  underwriting  discount  received by the
Underwriters,  in each case as set forth on the cover of the Prospectus,  or, if
Rule 434 is used,  the  corresponding  location on the Term  Sheet,  bear to the
aggregate initial public offering price of such  Underwritten  Securities as set
forth on such cover.

         The  relative  fault  of  the  Company,   on  the  one  hand,  and  the
Underwriters,  on the other hand,  shall be  determined  by reference  to, among
other things,  whether any such untrue or alleged untrue statement of a material
fact or omission or alleged omission to state a material fact relates to



                                      -25-

<PAGE>



information  supplied by the  Company or by the  Underwriters  and the  parties'
relative intent, knowledge,  access to information and opportunity to correct or
prevent such statement or omission.

         The  Company and the  Underwriters  agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata
allocation  (even  if the  Underwriters  were  treated  as one  entity  for such
purpose) or by any other method of allocation which does not take account of the
equitable  considerations  referred  to above in this  Section 7. The  aggregate
amount of losses,  liabilities,  claims,  damages  and  expenses  incurred by an
indemnified  party and  referred  to above in this  Section 7 shall be deemed to
include any legal or other  expenses  reasonably  incurred  by such  indemnified
party in investigating,  preparing or defending  against any litigation,  or any
investigation  or proceeding by any  governmental  agency or body,  commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

         Notwithstanding  the provisions of this Section 7, no Underwriter shall
be required to contribute  any amount in excess of the amount by which the total
price at which the Underwritten Securities underwritten by it and distributed to
the public were  offered to the public  exceeds the amount of any damages  which
such Underwriter has otherwise been required to pay by reason of any such untrue
or alleged untrue statement or omission or alleged omission.

         No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

         For purposes of this  Section 7, each  person,  if any, who controls an
Underwriter  within  the  meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such Underwriter, and
each  director  of the  Company,  each  officer  of the  Company  who signed the
Registration Statement, and each person, if any, who controls the Company within
the  meaning  of  Section 15 of the 1933 Act or Section 20 of the 1934 Act shall
have  the  same  rights  to  contribution  as  the  Company.  The  Underwriters'
respective  obligations to contribute  pursuant to this Section 7 are several in
proportion to the aggregate  principal  amount of  Underwritten  Securities  set
forth opposite their respective names in the applicable Terms Agreement, and not
joint.

         SECTION  8.  Representations,  Warranties  and  Agreements  to  Survive
Delivery.  All  representations,  warranties  and  agreements  contained in this
Underwriting  Agreement  or the  applicable  Terms  Agreement,  or  contained in
certificates  of officers of the  Company or any of its  subsidiaries  submitted
pursuant hereto or thereto, shall remain operative and in full force and effect,
regardless  of any  investigation  made by or on  behalf of any  Underwriter  or
controlling  person,  or by or on  behalf  of the  Company,  and  shall  survive
delivery of and payment for the Underwritten Securities.

         SECTION 9.        Termination of Agreement.

         (a)  This  Underwriting   Agreement  (excluding  the  applicable  Terms
Agreement)  may be  terminated  for any reason at any time by the  Company or by
Merrill  Lynch  upon  the  giving  of 30  days'  prior  written  notice  of such
termination to the other party hereto.

         (b) Merrill Lynch may  terminate the  applicable  Terms  Agreement,  by
notice to the Company, at any time at or prior to the Closing Time, if (i) there
has been,  since the time of  execution  of such  Terms  Agreement  or since the
respective  dates  as of which  information  is  given  in the  Prospectus,  any
material  adverse  change in the  condition,  financial or otherwise,  or in the
earnings,  business  affairs  or  business  prospects  of the  Company  and  its
subsidiaries  considered  as  one  enterprise,  whether  or not  arising  in the
ordinary  course of business,  or (ii) there has  occurred any material  adverse
change in the  financial  markets in the United  States or, if the  Underwritten
Securities include Debt Securities denominated or payable in, or indexed to, one
or more foreign or composite currencies, in the international financial markets,
or any outbreak of hostilities or escalation thereof or other calamity or crisis
or any change or  development  involving  a  prospective  change in  national or
international  political,  financial  or economic  conditions,  in each case the
effect of which is such as to make it, in the  reasonable  judgment  of  Merrill
Lynch,  impracticable  to  market  the  Underwritten  Securities  or to  enforce
contracts for the sale of the Underwritten  Securities,  or (iii) trading in any
securities  of the  Company  has been  suspended  or  materially  limited by the
Commission or the American Stock  Exchange,  or if trading  generally on the New
York Stock  Exchange or the American  Stock  Exchange or in the Nasdaq  National
Market has been  suspended or materially  limited,  or minimum or maximum prices
for trading have been fixed, or maximum ranges for prices have been required, by
either of said  exchanges or by such system or by order of the  Commission,  the
NASD or any other governmental  authority, or (iv) a banking moratorium has been
declared  by either  Federal  or New York  authorities  or, if the  Underwritten
Securities include Debt Securities denominated or payable in, or indexed to, one
or more foreign or composite  currencies,  by the  relevant  authorities  in the
related foreign country or countries, or (v) there has occurred,  since the time
of execution of such Terms  Agreement,  a downgrading  in, or withdrawal of, the
rating  assigned to the  Underwritten  Securities or any of the Company's  other
debt securities by a NRSRO, or any such NRSRO shall have publicly announced that
it has under  surveillance  or review with possible  negative  implications  its
rating  of the  Underwritten  Securities  or any of  the  Company's  other  debt
securities.

         (c) If this Underwriting Agreement or the applicable Terms Agreement is
terminated  pursuant  to this  Section  9,  such  termination  shall be  without
liability  of any  party to any other  party  except as  provided  in  Section 4
hereof,  and  provided  further that  Sections 1, 6, 7 and 8 shall  survive such
termination and remain in full force and effect.

         SECTION 10. Default by One or More of the Underwriters.  If one or more
of the Underwriters  shall fail at the Closing Time to purchase the Underwritten
Securities which it or they are obligated to purchase under the applicable Terms
Agreement (the "Defaulted Securities"), then Merrill Lynch and the Company shall
each have the right, within 24 hours thereafter, to make



                                      -27-

<PAGE>



arrangements for one or more of the  non-defaulting  Underwriters,  or any other
underwriters  reasonably  acceptable to Merrill Lynch,  to purchase all, but not
less than all, of the Defaulted Securities in such amounts as may be agreed upon
and upon the terms herein set forth;  if, however,  Merrill Lynch shall not have
completed such arrangements within such 24-hour period, then:

         (a) if the aggregate principal amount of Defaulted  Securities does not
exceed 10% of the aggregate  principal  amount of Underwritten  Securities to be
purchased  on such date  pursuant to such Terms  Agreement,  the  non-defaulting
Underwriters shall be obligated, severally and not jointly, to purchase the full
amount thereof in the proportions that their respective underwriting obligations
under  such  Terms  Agreement  bear  to  the  underwriting  obligations  of  all
non-defaulting Underwriters, or

         (b) if the aggregate  principal amount of Defaulted  Securities exceeds
10% of the aggregate principal amount of Underwritten Securities to be purchased
on such date  pursuant  to such  Terms  Agreement,  such Terms  Agreement  shall
terminate without liability on the part of any non-defaulting Underwriter.

         No  action  taken  pursuant  to  this  Section  10  shall  relieve  any
defaulting Underwriter from liability in respect of its default.

         In the event of any such default which does not result in a termination
of the  applicable  Terms  Agreement,  either Merrill Lynch or the Company shall
have the right to postpone  the Closing  Time for a period not  exceeding  seven
days in order to effect any required  changes in the  Registration  Statement or
the Prospectus or in any other documents or arrangements.

         SECTION 11. Notices.  Except as otherwise provided in Section 6(d), all
notices  and other  communications  hereunder  shall be in writing  and shall be
deemed to have been duly given if mailed or  transmitted by any standard form of
telecommunication.  Notices to the  Underwriters  shall be  directed  to Merrill
Lynch at  Merrill  Lynch & Co.,  5500  Sears  Tower,  Chicago,  Illinois  60606,
attention  of Steve  Moss;  notices to the  Company  shall be  directed to it at
United States Cellular  Corporation,  8410 West Bryn Mawr,  Suite 700,  Chicago,
Illinois 60631-3486; Attention: Senior Vice President-Finance and Treasurer.

         SECTION 12.  Parties.  This  Underwriting  Agreement and the applicable
Terms  Agreement  shall each inure to the benefit of and be binding upon Merrill
Lynch,  the Company,  and,  upon  execution of such Terms  Agreement,  any other
Underwriters and their respective successors.  Nothing expressed or mentioned in
this  Underwriting  Agreement  or such Terms  Agreement  is intended or shall be
construed to give any person,  firm or corporation,  other than the Underwriters
and the Company and their respective  successors and the controlling persons and
officers and directors referred to in Sections 6 and 7 and their heirs and legal
representatives,  any legal or  equitable  right,  remedy  or claim  under or in
respect of this Underwriting  Agreement or such Terms Agreement or any provision
herein  or  therein  contained.  This  Underwriting  Agreement  and  such  Terms
Agreement and all conditions  and provisions  hereof and thereof are intended to
be for the sole



                                      -28-

<PAGE>



and  exclusive  benefit of the parties  hereto and thereto and their  respective
successors,  and said  controlling  persons and officers and directors and their
heirs and legal representatives, and for the benefit of no other person, firm or
corporation.  No purchaser of Underwritten Securities from any Underwriter shall
be deemed to be a successor by reason merely of such purchase.

         SECTION 13.  GOVERNING LAW AND TIME.  THIS UNDERWRITING AGREEMENT
AND ANY APPLICABLE TERMS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

         SECTION 14.  Effect of Headings.  The Article and

         adversely  affect  the  interests  of any  Holders of  Securities  then
         Outstanding).

         All  Securities  of any one series and  Coupons,  if any,  appertaining
thereto  shall be  substantially  identical,  except  in the case of  Registered
Securities  as to  denomination  and except as may  otherwise  be provided by or
pursuant to the Board Resolution or Officers'  Certificate  referred to above or
as set  forth in any  indenture  supplemental  hereto  referred  to  above.  All
Securities  of any one  series  need not be  issued  at the same time and may be
issued from time to time,  consistent  with the terms of this  Indenture,  if so
provided by or pursuant to such Board Resolution,  such Officers' Certificate or
in any such indenture supplemental hereto.

         SECTION 2.4 Authentication  and Delivery of Securities.  The Issuer may
from time to time deliver  Securities  of any series,  having  attached  thereto
appropriate  Coupons,  if  any,  executed  by  the  Issuer  to the  Trustee  for
authentication, together with the applicable documents referred to below in this
Section,  and  the  Trustee  shall  thereupon   authenticate  and  deliver  such
Securities to or upon the order of the Issuer (contained in the Issuer Order

                                      -13-

referred to below in this Section) or pursuant to such procedures  acceptable to
the Trustee and to such  recipients as may be specified  from time to time by an
Issuer  Order.  If so  provided  in or  pursuant  to  the  Board  Resolution  or
supplemental  indenture  establishing the Securities of any series, the maturity
date,  original  issue date,  interest rate and any other terms of any or all of
the Securities of such series and the Coupons, if any,  appertaining thereto may
be  determined by or pursuant to such Issuer Order and  procedures.  If provided
for in such  procedures,  such Issuer  Order may  authorize  authentication  and
delivery pursuant to oral or electronic instructions from the Issuer or its duly
authorized agent, which instructions shall be promptly confirmed in writing.  In
authenticating  such  Securities and accepting the  additional  responsibilities
under this  Indenture  in relation  to such  Securities,  the  Trustee  shall be
entitled to receive (but, in the case of subparagraphs 2, 3 and 4 below, only at
or  before  the time of the  first  request  of the  Issuer  to the  Trustee  to
authenticate  Securities  of such  series) and (subject to Section 6.1) shall be
fully  protected  in relying  upon,  unless and until such  documents  have been
superseded or revoked:

                  (1) an Issuer Order requesting such authentication and setting
         forth delivery  instructions if the securities and the Coupons, if any,
         are not to be delivered to the Issuer,  provided that,  with respect to
         Securities of a series subject to a Periodic Offering,  (a) such Issuer
         Order may be  delivered  by the Issuer to the Trustee at any time prior
         to the  delivery  to the Trustee of the  Securities  of such series for
         authentication  and delivery,  (b) the Trustee shall  authenticate  and
         deliver the  Securities of such series for original  issue from time to
         time,  in an aggregate  principal  amount not  exceeding  the aggregate
         principal  amount  established  for such series,  pursuant to an Issuer
         Order or pursuant to such  procedures  acceptable to the Trustee as may
         be specified  from time to time by an Issuer Order,  (c) if so provided
         in or  pursuant  to the  Board  Resolution  or  supplemental  indenture
         establishing the Securities of such series, the maturity date, original
         issue  date,  interest  rate and any  other  terms of any or all of the
         Securities  of such  series  may be  determined  by an Issuer  Order or
         pursuant to such procedures and (d) if provided for in such procedures,
         such Issuer Order may authorize authentication and delivery pursuant to
         oral or electronic  instructions from the Issuer or its duly authorized
         agent, which instructions shall be promptly confirmed in writing;

                  (2)  any  Board  Resolution,   Officers'   Certificate  and/or
         executed supplemental  indenture referred to in Sections 2.1 and 2.3 by
         or  pursuant  to which the forms  and terms of the  Securities  of such
         series and the Coupons, if any, were established;

                                      -14-

<PAGE>



                  (3) an Officers'  Certificate  setting forth the form or forms
         and terms of the  Securities  of such series and the  Coupons,  if any,
         stating  that  such  form or forms  and  terms  have  been  established
         pursuant to Sections  2.1 and 2.3 and comply with this  Indenture,  and
         covering such other matters as the Trustee may reasonably request; and

                  (4) at the option of the Issuer, either an Opinion of Counsel,
         or a  letter  addressed  to the  Trustee  permitting  it to  rely on an
         Opinion of Counsel, substantially to the effect that:

                           (a) the forms of the  Securities  of such  series and
                  the Coupons, if any, have been duly authorized and established
                  in conformity with the provisions of this Indenture;

                           (b) in the  case  of an  underwritten  offering,  the
                  terms  of  the  Securities  of  such  series  have  been  duly
                  authorized and  established in conformity  with the provisions
                  of this Indenture, and, in the case of an offering that is not
                  underwritten,  certain terms of the  Securities of such series
                  have  been  established  pursuant  to a Board  Resolution,  an
                  Officers'   Certificate   or  a   supplemental   indenture  in
                  accordance with the provisions of this Indenture and when such
                  other  terms as are to be  established  pursuant  to an Issuer
                  Order or  procedures  set forth in an Issuer  Order shall have
                  been   established,   all  such  terms  will  have  been  duly
                  authorized  by the  Issuer and will have been  established  in
                  conformity with the provisions of this Indenture;

                           (c)  when  the  Securities  of  such  series  and the
                  Coupons,  if  any,  have  been  executed  by  the  Issuer  and
                  authenticated by the Trustee in accordance with the provisions
                  of this  Indenture  and  delivered to and duly paid for by the
                  purchasers thereof, they will have been duly issued under this
                  Indenture and will be valid and legally binding obligations of
                  the Issuer,  enforceable in accordance  with their  respective
                  terms, subject to bankruptcy,  insolvency,  reorganization and
                  other laws of general  applicability  relating to or affecting
                  the enforcement of creditors' rights and to general principles
                  of  equity,  and  will be  entitled  to the  benefits  of this
                  Indenture;

                           (d) the  execution and delivery by the Issuer of, and
                  the  performance by the Issuer of its obligations  under,  the
                  Securities  and  Coupons,  if any,  will  not  contravene  any
                  provision of applicable law or the

                                      -15-

<PAGE>



                  certificate of  incorporation  or by-laws of the Issuer or, to
                  the best knowledge of such counsel, (i) any agreement or other
                  instrument  binding upon the Issuer or any of its subsidiaries
                  that  is  material   to  the  Issuer  and  its   subsidiaries,
                  considered as one enterprise,  or (ii) any judgment,  order or
                  decree  of any  governmental  body,  agency  or  court  having
                  jurisdiction over the Issuer or any of its subsidiaries; and

                           (e)  no  consent,  approval,  authorization,   order,
                  registration  or  qualification  of or with  any  governmental
                  agency or body having jurisdiction over the Issuer is required
                  for the  execution  and  delivery  of the  Securities  of such
                  series  by the  Issuer,  except  such  as have  been  obtained
                  (except  that  no  opinion  need  be  expressed  as  to  state
                  securities or Blue Sky laws).

                  The  Trustee  shall have the right to decline to  authenticate
and  deliver  any  Securities  of any series  under  this  Section  (other  than
Securities  the  forms  and  terms of  which  shall  have  been  established  by
supplemental  indenture) if the Trustee,  being  advised by counsel,  determines
that such  action may not  lawfully  be taken by the Issuer or if the Trustee in
good faith by its board of directors or board of trustees,  executive  committee
or a trust  committee  of  directors,  trustees or Responsible  Officers  shall
determine  that such action  would  expose the Trustee to personal  liability to
existing  Holders or would affect the  Trustee's  rights,  duties or  immunities
under the Securities of any such series, this Indenture or otherwise.

                  If the Issuer shall establish pursuant to Section 2.3 that the
Securities  of a series  are to be issued in the form of one or more  Registered
Global  Securities,  then the Issuer  shall  execute and the Trustee  shall,  in
accordance  with this  Section and the Issuer Order with respect to such series,
authenticate and deliver one or more Registered Global Securities that (i) shall
be in an aggregate  amount equal to the aggregate  principal amount specified in
such  Issuer  Order,  (ii)  shall be  registered  in the name of the  Depositary
therefor  or its  nominee,  (iii)  shall be  delivered  by the  Trustee  to such
Depositary or pursuant to such  Depositary's  instructions and (iv) shall bear a
legend substantially to the following effect:  "Unless and until it is exchanged
in whole or in part for Securities in definitive  registered form, this Security
may not be transferred except as a whole by the Depositary to the nominee of the
Depositary  or by a nominee  of the  Depositary  to the  Depositary  or  another
nominee  of  the  Depositary  or by the  Depositary  or any  such  nominee  to a
successor Depositary or a nominee of such successor Depositary."

                  Each  Depositary  designated  pursuant to Section 2.3 must, at
the time of its designation and at all times while it serves as Depositary, be a
clearing  agency  registered  under the  Exchange  Act and any other  applicable
statute or regulation.

                  SECTION 2.5 Execution of Securities.  The Securities  shall be
signed  on  behalf  of the  Issuer  by both  (a) its  Chairman  of the  Board of
Directors or its President or any Vice President (whether or not designated by a
number or  numbers  or a word or words  added  before  or after the title  "Vice
President") and (b) by its Treasurer or any Assistant Treasurer or its Secretary
or any  Assistant  Secretary,  under its  corporate  seal (except in the case of
Coupons) which may, but need not, be attested. Such signatures may be the manual
or facsimile signatures of the present or any future such officers.  The seal of
the  Issuer  may be in the form of a  facsimile  thereof  and may be  impressed,
affixed, imprinted or otherwise reproduced on the Securities.  Typographical and
other minor errors or defects in any such  reproduction  of the seal or any such
signature shall not affect the validity or  enforceability  of any Security that
has been duly authenticated and delivered by the Trustee.  The Coupons,  if any,
applicable to the Securities of any series shall bear the facsimile signature of
the Treasurer or any Assistant Treasurer of the Issuer.

         In case any  officer  of the Issuer who shall have so signed any of the
Securities  or  Coupons,  if any,  shall  cease to be such  officer  before  the
Security  or Coupon so signed  (or the  Security  to which the  Coupon so signed
appertains)  shall be authenticated  and delivered by the Trustee or disposed of
by the Issuer,  such Security or Coupon  nevertheless may be  authenticated  and
delivered or disposed of as though the person who signed such Security or Coupon
had not ceased to be such officer of the Issuer;  and any Security or Coupon may
be so signed on behalf of the Issuer by such  persons  as, at the actual date of
the  execution of such Security or Coupon,  shall be the proper  officers of the
Issuer, although at the date of the execution and delivery of this Indenture any
such person was not such an officer.

                  SECTION  2.6   Certificate   of   Authentication.   Only  such
Securities as shall bear thereon a certificate of  authentication  substantially
in the  form  hereinbefore  recited,  executed  by  the  Trustee  by the  manual
signature of one of its authorized  officers,  shall be entitled to the benefits
of this Indenture or be valid or obligatory for any purpose.  No Coupon shall be
entitled to the benefits of this  Indenture or shall be valid and obligatory for
any purpose until the  certificate  of  authentication  on the Security to which
such  Coupon  appertains  shall  have been duly  executed  by the  Trustee.  The
execution of such certificate by the Trustee upon any Security executed by the

                                      -17-

<PAGE>



Issuer shall be conclusive  evidence that the Security so authenticated has been
duly  authenticated  and delivered  hereunder and that the Holder is entitled to
the benefits of this Indenture.

                  SECTION 2.7 Denomination  and Date of Securities,  Payments of
Interest.  The  Securities  of each  series  shall  be  issuable  as  Registered
Securities  or   Unregistered   Securities  in   denominations   established  as
contemplated by Section 2.3 or, with respect to the Registered Securities of any
series,  if not so  established,  in  denominations  of $1,000 and any  integral
multiple thereof. If denominations of Unregistered  Securities of any series are
not so established, such Securities shall be issuable in denominations of $1,000
and  $5,000.  The  Securities  of each  series  shall be  numbered,  lettered or
otherwise  distinguished  in such manner or in accordance  with such plan as the
officers of the Issuer executing the same may determine with the approval of the
Trustee, as evidenced by the execution and authentication thereof.

                  Each  Registered  Security  shall  be  dated  the  date of its
authentication.  Each Unregistered  Security shall be dated as established in or
pursuant  to the Board  Resolution  or  supplemental  indenture  referred  to in
Section 2.3. The Securities of each series shall bear interest, if any, from the
date,  and  such  interest  shall  be  payable  on  the  dates,  established  as
contemplated by Section 2.3.

                  Except as may  otherwise  be  established  pursuant to Section
2.3,  the  Person  in whose  name  any  Registered  Security  of any  series  is
registered at the close of business on any Record Date applicable to such series
with respect to any  interest  payment date for such series shall be entitled to
receive  the  interest,   if  any,   payable  on  such  interest   payment  date
notwithstanding  any transfer or exchange of such Registered Security subsequent
to the Record Date and prior to such interest payment date, except if and to the
extent  the Issuer  shall  default in the  payment of the  interest  due on such
interest payment date, in which case such defaulted  interest may, at the option
of the  Issuer,  be paid to the Persons in whose  names  Outstanding  Registered
Securities  of  such  series  are  registered  at the  close  of  business  on a
subsequent  special Record Date (which shall be not less than five Business Days
prior to the date of payment of such defaulted  interest)  established by notice
given  by mail by or on  behalf  of the  Issuer  to the  Holders  of  Registered
Securities  of such  series  not less  than 15 days  preceding  such  subsequent
special  Record  Date.  The term  "Record  Date",  as used with  respect  to any
interest payment date (except a special Record Date set for payment of defaulted
interest) for the Securities of any series, shall mean the date specified as

                                      -18-

<PAGE>



such in the terms of the  Registered  Securities of such series  established  as
contemplated by Section 2.3.

                  SECTION 2.8  Registration, Transfer and Exchange.  The
Issuer will keep, or cause to be kept, at the Corporate Trust Office or at 
another office or agency to be maintained for the purpose as provided in Section
3.2, for each series of Securities a register (the "Security Register") in 
which, subject to such reasonable regulations as it may prescribe, it will
provide for the registration of Registered Securities of such series and the
registration of transfer of Registered Securities of such series. The Security 
Register shall be in written form in the English language or in any other form 
capable of being converted into such form within a reasonable time.  At all 
reasonable times such register not maintained by the Trustee shall be open for
inspection by the Trustee.  Unless and until otherwise determined by the Issuer 
pursuant to Section 2.3, the Security Register with respect to each series of 
Registered Securities shall be kept solely at the Corporate Trust Office and, 
for this purpose, the Trustee shall be designated the "Security Registrar".

                  Upon due  presentation  for  registration  of  transfer of any
Registered  Security of any series at any office or agency to be maintained  for
the purpose as provided in Section 3.2 for such series, the Issuer shall execute
and the Trustee shall  authenticate and deliver in the name of the transferee or
transferees  a new  Registered  Security or  Registered  Securities  of the same
series,  maturity date and interest rate in authorized  denominations for a like
aggregate principal amount.

                  Unregistered  Securities  (except  for  any  temporary  global
Unregistered  Securities)  and  Coupons  (except  for  Coupons  attached  to any
temporary global Unregistered Securities) shall be transferable by delivery.

                  At the option of the Holder thereof,  Registered Securities of
any series (other than a Registered Global Security,  except as set forth below)
may be  exchanged  for one or more  Registered  Securities  of  such  series  in
authorized  denominations for a like aggregate  principal amount, upon surrender
of such  Registered  Securities  to be  exchanged  at the office or agency to be
maintained for such purpose in accordance with Section 3.2 and upon payment,  if
the  Issuer  shall so  require,  of the  charges  hereinafter  provided.  If the
Securities of any series are issued in both  registered and  unregistered  form,
except as otherwise  specified for a particular  series pursuant to Section 2.3,
at the option of the Holder thereof,  Unregistered  Securities of any series may
be  exchanged   for   Registered   Securities   of  such  series  in  authorized
denominations for a like aggregate principal amount, upon surrender of such

                                      -19-

<PAGE>



Unregistered Securities to be exchanged at the office or agency to be maintained
for  such  purpose  in  accordance  with  Section  3.2,  with,  in the  case  of
Unregistered  Securities that have Coupons  attached,  all unmatured Coupons and
all matured Coupons in default thereto  appertaining,  and upon payment,  if the
Issuer shall so require, of the charges hereinafter  provided.  At the option of
the Holder  thereof,  if Unregistered  Securities of any series,  maturity date,
interest  rate and  original  issue date are issued in more than one  authorized
denomination,  except as otherwise specified for a particular series pursuant to
Section  2.3,  such   Unregistered   Securities   may  be  exchanged  for  other
Unregistered  Securities of such series in authorized  denominations  for a like
aggregate principal amount, upon surrender of such Unregistered Securities to be
exchanged  at the  office  or  agency  to be  maintained  for  such  purpose  in
accordance with Section 3.2 or as specified for a particular  series pursuant to
Section 2.3,  with,  in the case of  Unregistered  Securities  that have Coupons
attached,  all  unmatured  Coupons  and all matured  Coupons in default  thereto
appertaining,  and upon payment,  if the Issuer shall so require, of the charges
hereinafter  provided.  Unless  otherwise  specified  for  a  particular  series
pursuant  to  Section  2.3,  Registered  Securities  of any  series  may  not be
exchanged for  Unregistered  Securities of such series.  Whenever any securities
are so surrendered for exchange, the Issuer shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive. All Securities and Coupons surrendered upon any exchange or
transfer provided for in this Indenture shall be promptly cancelled and disposed
of (subject to the record  retention  requirements  of the Exchange  Act) by the
Trustee and the Trustee will deliver a certificate of disposition thereof to the
Issuer.

         All  Registered  Securities  presented  for  registration  of transfer,
exchange,  redemption  or  payment  shall (if so  required  by the Issuer or the
Trustee) be duly  endorsed  by, or be  accompanied  by a written  instrument  or
instruments of transfer in form  satisfactory to the Issuer and the Trustee duly
executed by, the Holder or his attorney duly authorized in writing.

         The Issuer may require  payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any exchange or
registration of transfer of Securities.  No service charge shall be made for any
such transaction.

         The Issuer  shall not be required to (a) issue,  exchange or register a
transfer of any  Securities of any series for a period of 15 days next preceding
the first mailing or  publication  of notice of redemption of Securities of such
series to be redeemed,  (b) exchange or register the transfer of any  Securities
selected,

                                      -20-

<PAGE>



called or being called for redemption,  in whole or in part, except, in the case
of any  Security  to be  redeemed  in part,  the  portion  thereof  not so to be
redeemed or (c)  register the transfer of or exchange any Security if the Holder
thereof has  exercised  his right,  if any, to require the Issuer to  repurchase
such Security, in whole or in part, except the portion of such Security required
to be repurchased.

         Notwithstanding  any other provision of this Section,  unless and until
it is  exchanged in whole or in part for  Securities  in  definitive  registered
form,  a  Registered  Global  Security  representing  all  or a  portion  of the
Securities  of a  series  may  not  be  transferred  except  as a  whole  by the
Depositary for such  Registered  Global Security to a nominee of such Depositary
or by a nominee of such Depositary to such Depositary or another nominee of such
Depositary or by such  Depositary or any such nominee to a successor  Depositary
for such Registered Global Security or a nominee of such successor Depositary.

         If at any time a Depositary for any  Registered  Securities of a series
represented by one or more Registered Global Securities notifies the Issuer that
it is  unwilling  or  unable  to  continue  as  Depositary  for such  Registered
Securities  or if at any time any such  Depositary  shall no longer be  eligible
under Section 2.4, the Issuer shall appoint a successor  Depositary with respect
to the Registered Securities held by such Depositary.  If a successor Depositary
is not  appointed by the Issuer  within 90 days after the Issuer  receives  such
notice or becomes aware of such ineligibility, the Registered Securities of such
series  shall  no  longer  be  represented  by one  or  more  Registered  Global
Securities  held by such  Depositary,  and the  Issuer  shall  execute,  and the
Trustee,  upon receipt of an Issuer Order for the authentication and delivery of
definitive  Securities of such series, shall authenticate and deliver Securities
of such series in definitive  registered form without Coupons, in any authorized
denominations and in an aggregate principal amount equal to the principal amount
of the  Registered  Global  Security or  Securities  held by such  Depositary in
exchange for such Registered Global Security or Securities.

         Within seven days after the occurrence of an Event of Default specified
in  clause  (a),  (b) or (c) of  Section  5.1  with  respect  to any  series  of
Securities  that is, in whole or in part,  represented  by a  Registered  Global
Security,  the Issuer shall  execute,  and the Trustee  shall  authenticate  and
deliver,  Securities  of such  series  in  definitive  registered  form  without
coupons,  in any authorized  denominations and in an aggregate  principal amount
equal to the principal  amount of the Registered  Global  Security or Securities
representing   Registered  Securities  of  such  series  in  exchange  for  such
Registered Global Security or Securities.

                                      -21-

<PAGE>



         The Issuer may at any time and in its sole  discretion  determine  that
the Registered  Securities of a particular series shall no longer be represented
by a Registered  Global Security or Securities.  In such event, the Issuer shall
execute, and the Trustee, upon receipt of an Issuer Order for the authentication
and delivery of definitive  Securities of such series,  shall  authenticate  and
deliver,  Securities  of such  series  in  definitive  registered  form  without
Coupons,  in any authorized  denominations and in an aggregate  principal amount
equal to the principal  amount of the Registered  Global  Security or Securities
representing   Registered  Securities  of  such  series  in  exchange  for  such
Registered Global Security or Securities.

         If so specified  by the Issuer  pursuant to Section 2.3 with respect to
Securities of a particular  series  represented by a Registered Global Security,
the Depositary for such Registered Global Security may surrender such Registered
Global Security in exchange in whole or in part for Securities of such series in
definitive  registered  form on such terms as are  acceptable  to the Issuer and
such  Depositary.  Thereupon,  the Issuer shall  execute,  and the Trustee shall
authenticate and deliver:

                  (i)  to  each  Person  specified  by  such  Depositary  a  new
         Registered  Security or  securities of such series,  in any  authorized
         denominations  requested  by such  Person,  in an  aggregate  principal
         amount equal to, and in exchange for, such Person's beneficial interest
         in the Registered Global Security; and

                  (ii) to such Depositary a new Registered  Global Security in a
         denomination  equal to the difference  between the principal  amount of
         the surrendered  Registered Global Security and the aggregate principal
         amount of Registered Securities authenticated and delivered pursuant to
         clause (i) above.

                  Upon  the  exchange  of any  Registered  Global  Security  for
Securities  in  definitive   registered  form  without  Coupons,  in  authorized
denominations,  such Registered Global Security shall be canceled by the Trustee
or an agent of the Issuer or the Trustee.  Securities in  definitive  registered
form  without  Coupons  issued in  exchange  for a  Registered  Global  Security
pursuant  to  this  Section  shall  be  registered  in  such  names  and in such
authorized  denominations as the Depositary for such Registered Global Security,
pursuant to instructions from its direct or indirect  participants or otherwise,
shall instruct the Trustee or an agent of the Issuer or the Trustee. The Trustee
or such agent shall deliver such  Securities to or as directed by the Persons in
whose names such Securities are so registered.

                  All  Securities  issued upon any  registration  of transfer or
exchange of Securities shall be valid obligations of the Issuer,  evidencing the
same debt,  and  entitled  to the same  benefits  under this  Indenture,  as the
Securities surrendered upon such registration of transfer or exchange.

                  Notwithstanding  anything herein or in the terms of any series
of Securities to the contrary,  none of the Issuer,  the Trustee or any agent of
the Issuer or the Trustee (any of which, other than the Issuer, shall rely on an
Officers'  Certificate  and an Opinion of Counsel) shall be required to exchange
any  Unregistered  Security for a  Registered  Security if such  exchange  would
result in adverse  Federal income tax  consequences  to the Issuer (such as, for
example,  the inability of the Issuer to deduct from its income, as computed for
Federal  income  tax  purposes,   the  interest   payable  on  the  Unregistered
Securities) under then applicable United States Federal income tax laws.

                  SECTION 2.9  Mutilated,  Defaced,  Destroyed,  Lost and Stolen
Securities.  In  case  any  temporary  or  definitive  Security  or  any  Coupon
appertaining  to any Security shall become  mutilated,  defaced or be destroyed,
lost or stolen,  the Issuer shall execute,  and upon receipt of an Issuer Order,
the Trustee  shall  authenticate  and deliver a new Security of the same series,
maturity date,  interest rate and original issue date, bearing a number or other
distinguishing  symbol  not  contemporaneously   outstanding,  in  exchange  and
substitution  for  the  mutilated  or  defaced  Security,  or in  lieu of and in
substitution  for the  Security  so  destroyed,  lost or  stolen,  with  Coupons
corresponding  to the  Coupons  appertaining  to the  Securities  so  mutilated,
defaced,  destroyed,  lost or stolen,  or in  exchange or  substitution  for the
Security to which such  mutilated,  defaced,  destroyed,  lost or stolen  Coupon
appertained,  with Coupons appertaining thereto  corresponding to the Coupons so
mutilated, defaced, destroyed, lost or stolen. In every case the applicant for a
substitute Security or Coupon shall furnish to the Issuer and to the Trustee and
any agent of the Issuer or the  Trustee  such  security or  indemnity  as may be
required by them to indemnify  and defend and to save each of them harmless and,
in every case of destruction,  loss or theft,  evidence to their satisfaction of
the  destruction,  loss or theft of such Security or Coupon and of the ownership
thereof  and, in the case of  mutilation  or  defacement,  shall  surrender  the
Security and related Coupons to the Trustee or such agent.

                  Upon the issuance of any  substitute  Security or Coupon,  the
Issuer may  require the  payment 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 or its agent) connected
therewith. In case any Security or Coupon which has matured or is about to

                                      -23-

<PAGE>



mature or has been  called for  redemption  in full shall  become  mutilated  or
defaced or be destroyed,  lost or stolen,  the Issuer may,  instead of issuing a
new or  substitute  Security,  pay or  authorize  the payment of the same or the
relevant Coupon (without  surrender thereof except in the case of a mutilated or
defaced Security or Coupon),  if the applicant for such payment shall furnish to
the Issuer and to the Trustee  and any agent of the Issuer or the  Trustee  such
security or indemnity as may be required by them to save each of them  harmless,
and, in every case of destruction, loss or theft, evidence to their satisfaction
of the  destruction,  loss  or  theft  of such  Security  or  Coupon  and of the
ownership thereof and, in the case of mutilation or defacement,  shall surrender
the Security and related Coupons to the Trustee or such agent.

         Every  substitute  Security or Coupon of any series issued  pursuant to
the  provisions  of this Section by virtue of the fact that any such Security or
Coupon is destroyed,  lost or stolen shall constitute an additional  contractual
obligation of the Issuer, whether or not the destroyed,  lost or stolen Security
or Coupon  shall be at any time  enforceable  by anyone and shall be entitled to
all the benefits of (but shall be subject to all the  limitations  of rights set
forth in) this  Indenture  equally  and  proportionately  with any and all other
Securities or Coupons of such series duly authenticated and delivered hereunder.
All  Securities  and Coupons shall be held and owned upon the express  condition
that,  to the extent  permitted by law, the foregoing  provisions  are exclusive
with respect to the  replacement  or payment of mutilated,  defaced,  destroyed,
lost or stolen  Securities  and  Coupons  and shall  preclude  any and all other
rights or remedies  notwithstanding  any law or statute  existing  or  hereafter
enacted to the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

         SECTION 2.10  Cancellation  of  Securities;  Disposition  Thereof.  All
Securities and Coupons  surrendered  for payment,  redemption,  registration  of
transfer or exchange,  or for credit against any payment in respect of a sinking
or analogous  fund, if  surrendered  to the Issuer or any agent of the Issuer or
any agent of the  Trustee,  shall be  delivered  to the Trustee or its agent for
cancellation or, if surrendered to the Trustee,  shall be canceled by it; and no
Securities  or  Coupons  shall be issued  in lieu  thereof  except as  expressly
permitted by any of the provisions of this  Indenture.  The Trustee or its agent
shall  dispose of canceled  Securities  and  Coupons  held by it (subject to the
record retention  requirements of the Exchange Act) and deliver a certificate of
disposition  to the Issuer.  If the Issuer or its agent shall acquire any of the
Securities  or Coupons,  such  acquisition  shall not operate as a redemption or
satisfaction of the indebtedness represented by such Securities

                                      -24-

<PAGE>



or Coupons unless and until the same are delivered to the Trustee or its agent
for cancellation.

         SECTION  2.11  Temporary   Securities.   Pending  the   preparation  of
definitive  Securities  for any  series,  the Issuer may execute and the Trustee
shall  authenticate and deliver  temporary  Securities for such series (printed,
lithographed,  typewritten  or  otherwise  reproduced,  in  each  case  in  form
satisfactory  to the  Trustee).  Temporary  Securities  of any  series  shall be
issuable as Registered Securities without coupons, or as Unregistered Securities
with or without coupons attached thereto,  of any authorized  denomination,  and
substantially  in the form of the definitive  Securities of such series but with
such  omissions,  insertions and variations as may be appropriate  for temporary
Securities,  all as may be determined by the Issuer with the  concurrence of the
Trustee as evidenced by the  execution  and  authentication  thereof.  Temporary
Securities  may contain such  references to any  provisions of this Indenture as
may be appropriate. Every temporary Security shall be executed by the Issuer and
be  authenticated  by the Trustee upon the same conditions and in  substantially
the same manner,  and with like effect,  as the definitive  Securities.  Without
unreasonable  delay  the  Issuer  shall  execute  and shall  furnish  definitive
Securities of such series and thereupon temporary Registered  Securities of such
series  may be  surrendered  in  exchange  for  such  definitive  Securities  in
registered  form without  charge at each office or agency to be  maintained  for
such purpose in  accordance  with  Section 3.2 and, in the case of  Unregistered
Securities,  at any  office or  agency  to be  maintained  for such  purpose  as
specified  pursuant to Section  2.3,  and the  Trustee  shall  authenticate  and
deliver  in  exchange  for such  temporary  Securities  of such  series an equal
aggregate  principal  amount  of  definitive  Securities  of the same  series in
authorized  denominations  and, in the case of Unregistered  Securities,  having
attached  thereto any  appropriate  Coupons.  Until so exchanged,  the temporary
Securities  of any series  shall be  entitled  to the same  benefits  under this
Indenture as definitive  Securities of such series, unless otherwise established
pursuant  to Section  2.3.  The  provisions  of this  Section are subject to any
restrictions or limitations on the issue and delivery of temporary  Unregistered
Securities  of any  series  that may be  established  pursuant  to  Section  2.3
(including any provision that  Unregistered  Securities of such series initially
be issued in the form of a single global  Unregistered  Security to be delivered
to a depositary or agency  located  outside the United States and the procedures
pursuant to which  definitive  Unregistered  Securities  of such series would be
issued in exchange for such temporary global Unregistered Security).

                                  ARTICLE THREE

                             COVENANTS OF THE ISSUER
                             -----------------------

         SECTION 3.1 Payment of Principal and Interest. The Issuer covenants and
agrees  for the  benefit  of each  series  of  Securities  that it will duly and
punctually  pay or cause to be paid the  principal  of, and interest on, each of
the  Securities of such series  (together with any  additional  amounts  payable
pursuant  to the  terms  of such  Securities)  at the  place or  places,  at the
respective  times  and in the  manner  provided  in such  Securities  and in the
Coupons,  if any,  appertaining  thereto and in this Indenture.  The interest on
Securities with Coupons attached  (together with any additional  amounts payable
pursuant  to  the  terms  of  such  Securities)   shall  be  payable  only  upon
presentation and surrender of the several Coupons for such interest installments
as are evidenced thereby as they severally mature. If any temporary Unregistered
Security provides that interest thereon may be paid while in temporary form, the
interest  on  any  such  temporary  Unregistered  Security  (together  with  any
additional  amounts  payable  pursuant to the terms of such  Security)  shall be
paid, as to the installments of interest  evidenced by Coupons attached thereto,
if any,  only upon  presentation  and  surrender  thereof,  and, as to the other
installments  of interest,  if any,  only upon  presentation  of such  temporary
Unregistered  Security for notation thereon of the payment of such interest,  in
each case  subject to any  restrictions that may be  established  pursuant  to
Section 2.3. The interest on Registered Securities (together with any additional
amounts payable pursuant to the terms of such Securities)  shall be payable only
to or upon the written  order of the Holders  thereof  and, at the option of the
Issuer  (unless  otherwise  specified in such  Securities),  may be paid by wire
transfer or by mailing  checks for such interest  payable to or upon the written
order of such  Holders at their last  addresses  as they appear on the  registry
books of the Issuer.

         Principal and interest  shall be considered  paid on the date due if on
such  date the  Trustee  or the  paying  agent  holds in  accordance  with  this
Indenture  money  sufficient  to pay all principal and interest then due and the
Trustee or the paying agent,  as the case may be, is not prohibited  pursuant to
the terms of this  Indenture  from paying such money to the  Securityholders  on
that date.

         SECTION  3.2  Offices  for  Payments,  etc.  So long as any  Registered
Securities are outstanding hereunder, the Issuer will maintain in the Borough of
Manhattan,  The City of New  York,  an office  or  agency  where the  Registered
Securities of each series may be presented for payment,  where the Securities of
each series may be presented for exchange as in this Indenture provided and

                                      -26-

<PAGE>



where the Registered Securities of each series may be presented for registration
of transfer as in this Indenture provided.

         In the event that the Issuer shall issue any  Unregistered  Securities,
it will  maintain  one or more  offices or agencies in a city or cities  located
outside the United States  (including any city in which such an office or agency
is required to be maintained  under the rules of any stock exchange on which the
Securities of any series are listed) where the Unregistered Securities,  if any,
of each series and Coupons,  if any,  appertaining  thereto may be presented for
payment.  No payment on any  Unregistered  Security  or Coupon will be made upon
presentation of such Unregistered  Security or Coupon at an office or agency of
the Issuer within the United States, nor will any payment be made by transfer to
an account in, or by mail to an address in, the United States unless pursuant to
applicable United States laws and regulations then in effect such payment can be
made  without  adverse  tax  consequences  to the  Issuer.  Notwithstanding  the
foregoing,  payments  in Dollars on  Unregistered  Securities  of any series and
Coupons  appertaining  thereto  which are  payable in Dollars  may be made at an
office or agency of the Issuer maintained in the Borough of Manhattan,  The City
of New York,  if such payment in Dollars at each office or agency  maintained by
the Issuer outside the United States for payment on such Unregistered Securities
is illegal or  effectively  precluded  by  exchange  controls  or other  similar
restrictions.

         The Issuer will maintain in the Borough of  Manhattan,  The City of New
York,  an office or agency  where  notices  and demands to or upon the Issuer in
respect of the  Securities of any series,  the Coupons  appertaining  thereto or
this Indenture may be served.

         The Issuer will give to the Trustee  written  notice of the location of
each such  office or agency and of any change of location  thereof.  In case the
Issuer shall fail to maintain  any office or agency  required by this Section to
be located in the Borough of  Manhattan,  The City of New York, or shall fail to
give such notice of the  location or of any change in the location of any of the
above offices or agencies, presentations and demands may be made and notices may
be served at the Corporate Trust Office of the Trustee.

         The  Issuer  may from  time to time  designate  one or more  additional
offices  or  agencies  where  the  Securities  of any  series  and  any  Coupons
appertaining thereto may be presented for payment,  where the Securities of such
series may be presented for exchange as in this Indenture provided and where the
Registered  Securities  of such  series may be  presented  for  registration  of
transfer  as in this  Indenture  provided,  and the Issuer may from time to time
rescind any such  designation;  provided,  however,  that no such designation or
rescission shall in any manner

                                      -27-

<PAGE>



relieve the Issuer of its  obligation to maintain any office or agency  required
to be provided for in this Section.  The Issuer will give to the Trustee  prompt
written notice of any such designation or rescission thereof.

                  SECTION  3.3  Appointment  to  Fill a  Vacancy  in  Office  of
Trustee. The Issuer, whenever necessary to avoid or fill a vacancy in the office
of Trustee,  will appoint, in the manner provided in Section 6.10, a Trustee, so
that  there  shall at all  times be a Trustee  with  respect  to each  series of
Securities hereunder.

                  SECTION 3.4 Paying Agents. Whenever the Issuer shall appoint a
paying  agent  other than the  Trustee  with  respect to the  Securities  of any
series, it will cause such paying agent to execute and deliver to the Trustee an
instrument  in which such agent  shall  agree with the  Trustee,  subject to the
provisions of this Section:

                  (a) that it will hold all sums  received  by it as such  agent
         for the payment of the  principal of or interest on the  Securities  of
         such series (whether such sums have been paid to it by the Issuer or by
         any other  obligor on the  Securities  of such series) in trust for the
         benefit of the Holders of the Securities of such series and the Coupons
         appertaining thereto, if any, or of the Trustee, and

                  (b) that it will give the Trustee notice of any failure by the
         Issuer (or by any other  obligor on the  Securities  of such series) to
         make any payment of the  principal of or interest on the  Securities of
         such series when the same shall be due and payable, and

                  (c)  that at any  time  during  the  continuance  of any  such
         failure  referred  to in the  foregoing  paragraph  (b),  it will  upon
         written request of the Trustee forthwith pay to the Trustee all sums so
         held in trust by such agent.

                  The Issuer will, on or prior to each due date of the principal
of or interest on the Securities of any series,  deposit with the paying agent a
sum  sufficient  to pay such  principal or interest so becoming due, and (unless
such paying agent is the Trustee) the Issuer will promptly notify the Trustee of
any failure to take such action.

                  If the Issuer  shall act as its own paying  agent with respect
to the  Securities  of any  series,  it will,  on or before each due date of the
principal of or interest on the Securities of such series, set aside,  segregate
and hold in trust for the  benefit  of the  Holders  of the  Securities  of such
series or the

                                      -28-

<PAGE>



Coupons, if any,  appertaining thereto a sum sufficient to pay such principal or
interest so becoming  due.  The Issuer will  promptly  notify the Trustee of any
failure to take such action.

                  Anything in this section to the contrary notwith standing, but
subject  to  Section  10.1,  the  Issuer  may at any time,  for the  purpose  of
obtaining a satisfaction and discharge with respect to one or more or all series
of Securities hereunder, or for any other reason, pay or cause to be paid to the
Trustee  all sums held in trust for any such  series by the Issuer or any paying
agent  hereunder,  as  required  by this  Section,  such  sums to be held by the
Trustee upon the trusts herein contained.

                  Anything in this Section to the contrary notwithstanding, the
agreement  to hold sums in trust as provided  in this  Section is subject to the
provisions of Sections 10.3 and 10.4.

                  SECTION 3.5  Written  Statement  to  Trustee.  The Issuer will
deliver to the Trustee on or before April 30 in each year  (beginning with April
30, 1998) an  Officers'  Certificate  (which need not comply with Section  11.5)
stating that in the course of the  performance by the signers of their duties as
officers of the Issuer they would  normally have knowledge of any default by the
Issuer in the performance of any covenants contained in this Indenture,  stating
whether or not they have  knowledge of any such  default and, if so,  specifying
each such default of which the signers have knowledge and the nature thereof.

                  SECTION 3.6  Limitation on Secured Debt. So long as any of the
Securities remain  Outstanding,  the Issuer will not create or incur any Secured
Debt  without  in any such  case  effectively  providing  concurrently  with the
creation  or  incurrence  of any such  Secured  Debt  that the  Securities  then
Outstanding (together with, if the Issuer shall so determine,  any other Debt of
or  guaranteed  by the  Issuer  ranking  equally  with the  Securities  and then
existing or thereafter  created) shall be secured  equally and ratably with (or,
at the option of the Issuer,  prior to) such Secured  Debt,  unless  immediately
after the  incurrence  of such  Secured  Debt (and  after  giving  effect to the
application of the proceeds, if any, therefrom),  the aggregate principal amount
of all such Secured Debt, together with the aggregate amount of Capitalized Rent
in respect of Sale and  Leaseback  Transactions  (other than Sale and  Leaseback
Transactions described in clauses (a) to (e), inclusive, of Section 3.7), would
not exceed  10% of  Consolidated  Capitalization;  provided,  however,  that the
foregoing  restrictions  shall not apply to,  and  there  shall be  excluded  in
computing  Secured  Debt for the  purpose  of such  restrictions,  Secured  Debt
secured by:


                                      -29-

<PAGE>



                  (a) Liens on property  existing at the time of acquisition of
         such  property by the Issuer,  or Liens to secure the payment of all or
         any part of the purchase  price of property  acquired or constructed by
         the Issuer (including any improvements to existing property) created at
         the  time of or  within  270 days  following  the  acquisition  of such
         property by the Issuer, or Liens to secure any Secured Debt incurred by
         the Issuer  prior to, at the time of or within 270 days  following  the
         acquisition  of such  property,  which Secured Debt is incurred for the
         purpose of  financing  all or any part of the purchase  price  thereof;
         provided,  however, that in the case of any such acquisition,  the Lien
         shall  not  apply  to any  property  theretofore  owned  by the  Issuer
         (including property transferred by the Issuer to any subsidiary of the
         Issuer in  contemplation  of or in connection with the creation of such
         Lien) or to any  property  of the  Issuer  other than the  property  so
         acquired (other than, in the case of  construction or improvement,  any
         theretofore  unimproved  real property or portion  thereof on which the
         property so constructed, or the improvement, is located);

                  (b) Liens on  property  of a Person (i)  existing  at the time
         such  Person is merged into or  consolidated  with the Issuer or at the
         time of a sale,  lease  or other  disposition  of the  properties  of a
         Person as an entirety  or substantially as an entirety to the Issuer,
         (ii)  resulting  from  such  merger,  consolidation,   sale,  lease  or
         disposition  by virtue of any Lien on  property  granted  by the Issuer
         prior to such merger,  consolidation,  sale,  lease or disposition (and
         not in contemplation thereof or in connection therewith) which applies
         to  after-acquired  property of the Issuer or (iii) resulting from such
         merger, consolidation, sale, lease or disposition pursuant to a Lien or
         contractual  provision  granted or entered into by such Person prior to
         such merger, consolidation,  sale, lease or disposition (and not at the
         request of the Issuer); provided,  however, that any such Lien referred
         to in clause (i) shall not apply to any  property  of the Issuer  other
         than the property subject thereto at the time such Person or properties
         were  acquired  and any such Lien  referred  to in clause (ii) or (iii)
         shall not apply to any  property of the Issuer  other than the property
         so acquired;

                  (c)  Liens existing on the date of this Indenture;

                  (d) Liens in favor of a government or  governmental  entity to
         secure  partial   progress,   advance  or  other  payments,   or  other
         obligations,  pursuant to any contract or statute or to secure any Debt
         incurred  for the purpose of  financing  all or any part of the cost of
         acquiring, constructing or improving the property subject to such Liens

                                      -30-

<PAGE>



         (including,  without  limitation,  Liens  incurred in  connection  with
         pollution control, industrial revenue, private activity bond or similar
         financing);

                  (e) Liens arising by reason of deposits with, or the giving of
         any form of security to, any governmental agency or any body created or
         approved by law or governmental  regulation,  which Lien is required by
         law or governmental regulation as a condition to the transaction of any
         business  or the  exercise  of any  privilege,  franchise,  license  or
         permit;

                  (f) Liens for taxes,  assessments or  governmental  charges or
         levies not yet  delinquent or  governmental  charges or levies  already
         delinquent,  the validity of which charge or levy is being contested in

         with legal  proceedings so long as such proceedings are being contested
         in good faith and, in the case of judgment liens,  execution thereon is
         stayed and for which any reserves required in accordance with generally
         accepted accounting principles have been established; and

                  (h) any  extension,  renewal  or  replacement  (or  successive
         extensions,  renewals or  replacements) in whole or in part of any Lien
         referred to in the foregoing clauses (a) to (g),  inclusive;  provided,
         however,  that the  principal  amount of Secured Debt  secured  thereby
         shall not exceed the principal  amount of Secured Debt secured  thereby
         at the time of such extension,  renewal or  replacement,  and that such
         extension,  renewal or replacement shall be limited to all or a part of
         the property  which  secured the Lien so extended,  renewed or replaced
         (plus improvements to such property).

                  SECTION 3.7 Limitation on Sale and  Leaseback.  So long as any
of the Securities  remain  outstanding,  the Issuer will not enter into any Sale
and Leaseback Transaction unless immediately thereafter (and after giving effect

Capitalized  Rent in respect of Sale and Leaseback  Transactions,  together with
the  aggregate  principal  amount of all Secured  Debt (other than  Secured Debt
described in clauses (a) to (h),  inclusive,  of Section 3.6),  would not exceed

         existing  property)  or entered into prior to, at the time of or within
         270 days after the acquisition or construction of such property,  which
         Sale and  Leaseback  Transaction  is  entered  into for the  purpose of
         financing all or part of the purchase or  construction  price  thereof;
         provided, however, that in the case of any such acquisition,  such Sale

         the  Issuer to a  subsidiary  of the Issuer in  contemplation  of or in
         connection  with such Sale and  Leaseback  Transaction  or involve  any
         property of the Issuer other than the property so acquired (other than,

         the  properties  of a Person  as an  entirety  or  substantially  as an
         entirety to the Issuer;

                  (c) any Sale and Leaseback  Transaction in which the lessor is
         a  government  or  governmental  entity  and which  Sale and  Leaseback
         Transaction  is entered  into to secure  partial  progress,  advance or
         other  payments,  or other  obligations,  pursuant  to any  contract or
         statute or to secure any Debt incurred for the purpose of financing all
         or any part of the  cost of  constructing  or  improving  the  property
         subject  to such Sale and  Leaseback  Transaction  (including,  without
         limitation, Sale and Leaseback Transactions incurred in connection with
         pollution control, industrial revenue, private activity bond or similar
         financing);

                  (d)  any  Sale  and   Leaseback   Transaction   involving  the

         or  replacements) in whole or in part of a lease pursuant to a Sale and
         Leaseback  Transaction referred to in the foregoing clauses (a) to (c),
         inclusive;  provided,  however,  that such lease extension,  renewal or
         replacement  shall be limited  to all or any part of the same  property
         leased  under  the  lease  so  extended,   renewed  or  replaced  (plus
         improvements to such property); and

                  (e) any Sale and  Leaseback  Transaction  the net  proceeds of
         which are at least equal to the fair value (as  determined by the Board
         of  Directors)  of the  property  leased  pursuant  to  such  Sale  and
         Leaseback Transaction, so long as

                                      -32-

<PAGE>



         within  270  days of the  effective  date of such  Sale  and  Leaseback
         Transaction,  the Issuer applies (or  irrevocably  commits to an escrow
         account for the purpose or purposes  hereinafter  mentioned)  an amount
         equal to the net  proceeds of such Sale and  Leaseback  Transaction  to
         either (x) the purchase of other property  having a fair value at least
         equal  to the  fair  value  of the  property  leased  in such  Sale and
         Leaseback Transaction and having a similar utility and function, or (y)
         the  retirement or repayment  (other than any  mandatory  retirement or
         repayment at maturity) of (i) Securities, (ii) other Funded Debt of the
         Issuer which ranks prior to or on a parity with the Securities or (iii)
         indebtedness of any subsidiary of the Issuer maturing by its terms more
         than one  year  from its  date of  issuance  (notwithstanding  that any
         portion of such  indebtedness  is included in current  liabilities)  or
         preferred  stock of any  subsidiary  of the Issuer (other than any such
         indebtedness  owed to or  preferred  stock  owned by the  Issuer or any
         subsidiary of the Issuer); provided,  however, that in lieu of applying
         an amount  equivalent  to all or any part of such net  proceeds to such
         retirement  or  repayment  (or  committing  such an amount to an escrow
         account  for such  purpose),  the  Issuer may  deliver  to the  Trustee
         Outstanding  Securities  and  thereby  reduce  the amount to be applied
         pursuant  to (y) of this  clause  (e) by an  amount  equivalent  to the
         aggregate principal amount of the Securities so delivered.

                             ISSUER AND THE TRUSTEE
                    ----------------------------------------

                  SECTION 4.1 Issuer to Furnish  Trustee  Names and Addresses of
Securityholders. The Issuer and any other obligor on the Securities covenant and
agree that they will  furnish or cause to be  furnished to the Trustee a list in
such form as the Trustee may  reasonably  require of the names and  addresses of
the Holders of the Registered Securities of each series:

                  (a)  semi-annually and not more than 15 days after each Record
         Date for the payment of interest on such Registered  Securities,  as of
         such Record Date and on dates to be determined  pursuant to Section 2.3
         for non-interest bearing Registered Securities, in each year, and

                  (b) at such other times as the Trustee may request in writing,
         within 30 days after receipt by the Issuer of any such request, as of a

<PAGE>



         15 days prior to the time such information is furnished,

provided that if and so long as the Trustee shall be the Security  Registrar for
such series and all of the Securities of such series are Registered  Securities,
such list shall not be required to be furnished.

                  SECTION 4.2  Preservation  and  Disclosure of  Securityholders
Lists.  (a) The Trustee  shall  preserve,  in as current a form as is reasonably
practicable,  all  information  as to the names and  addresses of the Holders of
each  series of  Registered  Securities  (i)  contained  in the most recent list
furnished to it as provided in Section 4.1,  (ii) received by it in the capacity
of Security  Registrar  for such series,  if so acting,  and (iii) filed with it
within the two preceding years pursuant to Section  4.4(c)(ii).  The Trustee may
destroy any list  furnished  to it as provided in Section 4.1 upon  receipt of a
new list so furnished.

                  (b) In case three or more Holders of  Securities  (hereinafter
referred to as "applicants")  apply in writing to the Trustee and furnish to the
Trustee  reasonable  proof that each such  applicant  has owned a Security for a
period of at least six months preceding the date of such  application,  and such
application states that the applicants desire to communicate with other Holders
of Securities of a particular series (in which case the applicants must all hold
Securities  of such  series) or with Holders of all  Securities  with respect to
their rights under this Indenture or under such Securities and such  application
is accompanied by a copy of the form of proxy or other  communication which such
applicants  propose to transmit,  then the Trustee  shall,  within five Business
Days after the receipt of such application, at its election, either

                  (i)  afford  to  such  applicants  access  to the  information
         preserved at the time by the Trustee in accordance  with the provisions
         of subsection (a) of this Section, or

                  (ii) inform such  applicants as to the  approximate  number of
         Holders of Registered  Securities  of such series or of all  Registered
         Securities, as the case may be, whose names and addresses appear in the
         information  preserved at the time by the Trustee,  in accordance  with
         the provisions of such subsection (a) and as to the approximate cost of
         mailing to such  Holders the form of proxy or other  communication,  if
         any, specified in such application.

<PAGE>



                  If the Trustee  shall  elect not to afford to such  applicants
access to such information,  the Trustee shall, upon the written request of such
applicants,  mail to each  Holder of such  series or all  Holders of  Registered
Securities,  whose name and address appears in the information  preserved at the
time by the Trustee in accordance  with the provisions of such  subsection (a) a
copy of the  form of proxy or other  communication  which is  specified  in such
request,  with  reasonable  promptness  after a  tender  to the  Trustee  of the
material to be mailed and of  payment,  or  provision  for the  payment,  of the
reasonable  expenses of mailing,  unless  within five days after such tender the
Trustee shall mail to such  applicants  and file with the  Commission,  together
with a copy of the  material  to be mailed,  a written  statement  to the effect
that, in the opinion of the Trustee,  such mailing would be contrary to the best
interests  of the  Holders of  Registered  Securities  of such  series or of all
Registered  Securities,  as the  case  may  be,  or  would  be in  violation  of
applicable law. Such written  statement shall specify the basis of such opinion.
If the Commission, after opportunity for a hearing upon the objections specified
in the written statement so filed,  shall enter an order refusing to sustain any
of such objections or if, after the entry of an order  sustaining one or more of
such  objections,  the Commission  shall find,  after notice and opportunity for
hearing,  that all the objections so sustained have been met, and shall enter an
order so  declaring,  the Trustee shall mail copies of such material to all such
Holders with reasonable promptness after the entry of such order and the renewal
of such tender;  otherwise  the Trustee  shall be relieved of any  obligation or
duty to such applicants respecting their application.

                  (c) Each and  every  Holder  of  Securities  and  Coupons,  by
receiving  and  holding the same,  agrees  with the Issuer and the Trustee  that
neither  the Issuer nor the  Trustee  nor any agent of the Issuer or the Trustee
shall be held accountable by reason of the disclosure of any such information as
to the names and addresses of the Holders of  Securities in accordance  with the
provisions  of  subsection  (b) of this  Section,  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
such subsection (b).

                  (d) The Issuer shall upon written  request to the Trustee (or,
if  applicable,  the  Security  Registrar)  be entitled to receive a list of the
Holders of any and all series of Registered Securities.

         such  report,  with  a  brief  description  of  any  property  held  as

                  (e) (i) a default occurs under any instrument  (including this
         Indenture)  under which there is at the time  outstanding,  or by which
         there may be secured or evidenced,  any  indebtedness of the Issuer for
         money  borrowed by the Issuer  (other than  non-recourse  indebtedness)
         which results in acceleration (whether by declaration or automatically)
         of,  or  the  nonpayment  at  maturity  (after  giving  effect  to  any
         applicable grace period) of, such indebtedness in an aggregate amount

         exceeding   $30,000,000   or,  if   greater,   2%  of   Consolidated
         Capitalization,  in which case the Issuer shall immediately give notice
         to the  Trustee of such acceleration  or  non-payment  and (ii) there
         shall have been a failure to cure such default or to discharge all such
         defaulted  indebtedness  within  ten days after  notice  thereof to the
         Issuer by the  Trustee or to the Issuer and the  Trustee by the Holders
         of at least 25% in principal  amount of the Securities then Outstanding
         (excluding,  if such  defaulted  indebtedness  includes  any  series of
         Securities,  such series of Securities) and such acceleration shall not
         be  rescinded  or  annulled;  provided,  however,  that  it  shall  not
         constitute  an Event of  Default  hereunder  as long as the  Issuer  is
         contesting  any such  default  or  acceleration  in good  faith  and by
         appropriate proceedings; or

                  (f) a court having  jurisdiction in the premises shall enter a
         decree or order for relief in  respect of the Issuer in an  involuntary
         case under any applicable  bankruptcy,  insolvency or other similar law
         now or hereafter  in effect,  or  appointing  a receiver,  liquidator,
         assignee,  custodian,  trustee or sequestrator (or similar official) of
         the Issuer or for any  substantial  part of the property of the Issuer,
         or ordering the winding up or liquidation of the affairs of the Issuer,
         and such  decree or order  shall  remain  unstayed  and in effect for a
         period of 60 consecutive days; or

                  (g) the  Issuer  shall  commence  a  voluntary  case under any
         applicable bankruptcy, insolvency or other similar law now or hereafter
         in  effect,  or  consent  to the  entry of an order  for  relief  in an

         substantial  part of the  property of the  Issuer,  or make any general
         assignment for the benefit of creditors; or

                  (h) any other Event of Default  provided in or pursuant to the
         supplemental  indenture or Board Resolution  establishing the terms of
         such series of  Securities as provided in Section 2.3 or in the form of
         Security for such series.

If an Event of Default  described in clause (a), (b) or (c) shall have  occurred
and be continuing  with respect to the  Securities of any series,  then,  and in
each and every such case,  unless the principal of all of the Securities of such
series  shall have  already  become due and  payable,  either the Trustee or the
Holders

                                      -40-

<PAGE>



of not less than 25% in aggregate  principal  amount of the  Securities  of such
series then Outstanding,  by notice in writing to the Issuer (and to the Trustee
if  given  by  such  Holders),  may  declare  the  entire  principal  of all the
Securities of such series then  Outstanding and the interest  accrued thereon to
be due and payable  immediately,  and upon any such  declaration  the same shall
become  immediately due and payable.  If an Event of Default described in clause
(d) or (h) (if the Event of Default  under either clause is with respect to less
than all series of the Securities then  Outstanding)  shall have occurred and be
continuing  with respect to the  Securities  of one or more series,  then and in
each and every such case,  unless the principal of all of the Securities of such
series  shall have  already  become due and  payable,  either the Trustee or the
Holders of not less than 25% in aggregate  principal amount of the Securities of
all series affected thereby then Outstanding (voting as one class), by notice in
writing to the Issuer (and to the Trustee if given by such Holders), may declare
the entire  principal of all the  Securities  of all such  affected  series then
Outstanding and the interest accrued thereon to be due and payable  immediately,
and upon any such declaration the same shall become immediately due and payable.
If an Event of Default  described  in clause (d) or (h) (if the Event of Default
under  either  clause  is  with  respect  to  all  series  of  Securities   then
Outstanding)  or described in clause (e) shall have occurred and be  continuing,
then,  and in  each  and  every  such  case,  unless  the  principal  of all the
Securities shall have already become due and payable,  either the Trustee or the
Holders of not less than 25% in aggregate principal amount of all the Securities
then Outstanding  (voting as one class), by notice in writing to the Issuer (and
to the Trustee if given by such  Holders),  may declare the entire principal of
all the Securities then Outstanding and interest accrued thereon,  if any, to be
due and payable immediately, and upon any such declaration the same shall become
immediately due and payable.  If an Event of Default  described in clause (f) or
(g) shall have occurred and be continuing, the principal and interest on all the
Securities  then  Outstanding  shall thereby become and be  immediately  due and
payable  without any  declaration or other act on the part of the Trustee or any
Securityholders.

                  The foregoing paragraph,  however, is subject to the condition
that if, at any time after the principal of the Securities of one or more series
shall have been so declared due and  payable,  and before any judgment or decree
for the  payment  of the  moneys  due shall  have been  obtained  or  entered as
hereinafter  provided,  the Issuer shall pay or shall deposit with the Trustee a
sum  sufficient  to pay  all  matured  installments  of  interest  upon  all the
Securities  of such series and the  principal of all  Securities  of such series
which shall have become due otherwise than by  acceleration  (with interest upon
such  principal  and, to the extent that payment of such interest is enforceable
under

                                      -41-

<PAGE>



applicable law, on overdue installments of interest at the same rate as the rate
of  interest  (or Yield to  Maturity,  in the case of  Original  Issue  Discount
Securities)  specified in the  Securities  of such  series,  to the date of such
payment or deposit) and such amount as shall be sufficient  to cover  reasonable
compensation to the Trustee,  its agents,  attorneys and counsel,  and all other
expenses and liabilities incurred,  and all advances made, by the Trustee except
as a result of  negligence  or bad  faith,  and if any and all Events of Default
under this Indenture with respect to such series,  other than the non-payment of
the  principal  of  Securities  of such  series  which  shall have become due by
acceleration,  shall have been cured,  waived or otherwise  remedied as provided
herein--then,  and in every such case,  the Holders of a majority  in  aggregate
principal  amount of all the Securities of such affected series then Outstanding
(voting  as one  class,  except in the case of Events of  Default  described  in
clauses  (a),  (b) and (c) of such  paragraph,  in which  case  each  series  of
Securities as to which such an Event of Default  shall have occurred  shall vote
as a separate  class),  by written notice to the Issuer and to the Trustee,  may
waive all  defaults  with  respect  to such  series and  rescind  and annul such
declaration  and its  consequences,  but no  such  waiver  or  rescission  and
annulment shall extend to or shall affect any subsequent default or shall impair
any right consequent thereon.

                  For all  purposes  under this  Indenture,  if a portion of the
principal of any Original Issue Discount  Securities shall have been accelerated
and declared due and payable pursuant to the provisions  hereof,  then, from and
after such declaration, unless such declaration has been rescinded and annulled,
the principal amount of such Original Issue Discount Securities shall be deemed,
for all purposes hereunder, to be such portion of the principal thereof as shall
be due and payable as a result of such acceleration, and payment of such portion
of the  principal  thereof  as shall  be due and  payable  as a  result  of such
acceleration,  together  with  interest,  if any,  thereon and all other amounts
owing  thereunder,  shall  constitute  payment  in full of such  Original  Issue
Discount Securities.

                  SECTION 5.2 Collection of Indebtedness by Trustee; Trustee May
Prove Debt.  The Issuer  covenants that (a) in case default shall be made in the
payment of any  installment  of interest on any of the  Securities of any series
when such  interest  shall have become due and payable,  and such default  shall
have  continued for a period of 30 days, or (b) in case default shall be made in
the payment of all or any part of the principal of any of the  Securities of any
series when the same shall have  become due and  payable,  whether at  maturity,
upon  redemption,  by  declaration  or  otherwise  -- then,  upon  demand of the
Trustee,  the Issuer  will pay to the  Trustee for the benefit of the Holders of
the Securities of such series the whole amount

                                      -42-

<PAGE>



that then shall have become due and payable on all  Securities  of such  series,
including  all Coupons,  for  principal  or  interest,  as the case may be (with
interest  to the date of such  payment  upon the overdue  principal  and, to the
extent that payment of such interest is  enforceable  under  applicable  law, on
overdue  installments  of interest at the same rate as the rate of interest  (or
Yield to Maturity,  in the case of Original Issue Discount Securities) specified
in the Securities of such series); and in addition thereto,  such further amount
as shall be sufficient to cover the costs and expenses of collection,  including
reasonable  compensation to the Trustee, its agents,  attorneys and counsel, and
any expenses and  liabilities  incurred,  and all advances  made, by the Trustee
except as a result of its negligence or bad faith.

                  Until such demand is made by the  Trustee,  the Issuer may pay
the  principal of and interest on the  Securities of such series to the Holders,
whether or not the Securities of such series be overdue.

                  In case the Issuer  shall fail  forthwith  to pay such amounts
upon such  demand,  the  Trustee,  in its own name and as  trustee of an express
trust, shall be entitled and empowered to institute any action or proceedings at
law or in  equity  for the  collection  of the sums so due and  unpaid,  and may
prosecute any such action or  proceedings  to judgment or final decree,  and may
enforce any such  judgment or final decree  against the Issuer or other  obligor
upon the Securities of such series and collect in the manner provided by law out
of the  property  of the Issuer or other  obligor  upon the  Securities  of such
series, wherever situated the moneys adjudged or decreed to be payable.

                  In case there  shall be pending  proceedings  relative  to the
Issuer or any other obligor upon the  Securities of any series under Title 11 of
the United  States  Code or any other  applicable  Federal or state  bankruptcy,
insolvency or other  similar law, or in case a receiver,  assignee or trustee in
bankruptcy or reorganization,  liquidator,  sequestrator  or similar  official
shall have been appointed for or taken  possession of the Issuer or its property
or such other obligor, or in case of any other comparable  judicial  proceedings
relative to the Issuer or such other obligor, or to the creditors or property of
the Issuer or such other  obligor,  the  Trustee,  irrespective  of whether  the
principal  of the  Securities  of any series  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  pursuant to the  provisions of this Section,
shall  be  entitled  and  empowered,  by  intervention  in such  proceedings  or
otherwise:

                  (a) to file and prove a claim or claims  for the whole  amount
         of the principal and interest (or, if the  Securities of any series are
         Original Issue Discount

         Securities, such portion of the principal amount as may be specified in
         the terms of such series) owing and unpaid in respect of the Securities
         of each  series,  and to file such other  papers or documents as may be
         necessary or  advisable  in order to have the  claims of the  Trustee
         (including  any claim for  reasonable  compensation to the Trustee and
         its  agents,  attorneys  and  counsel,  and  for  reimbursement  of all
         expenses  and  liabilities  incurred,  and all  advances  made,  by the
         Trustee,  except as a result of  negligence  or bad  faith)  and of the
         Securityholders  allowed in any judicial  proceedings  relative to the
         Issuer or such other  obligor,  or to the  creditors or property of the
         Issuer or such other obligor,

                  (b) unless  prohibited by applicable law and  regulations,  to
         vote on behalf of the Holders of the  Securities  of each series in any
         election   of  a  trustee  or  a  standby   trustee   in   arrangement,
         reorganization,   liquidation   or  other   bankruptcy   or  insolvency
         proceedings  or  person  performing  similar  functions  in  comparable
         proceedings, and

                  (c) to  collect  and  receive  any  moneys  or other  property
         payable  or  deliverable  on any such  claims,  and to  distribute  all
         amounts received with respect to the claims of the  Securityholders and
         of the Trustee on their behalf; and any trustee, receiver,  liquidator,
         custodian or other similar official is hereby authorized by each of the
         Securityholders to make payments to the Trustee, and, in the event that
         the Trustee  shall  consent to the making of  payments  directly to the
         Securityholders,  to  pay to the  Trustee  such  amounts  as  shall  be
         sufficient to cover  reasonable  compensation  to the Trustee,  and its
         agents,  attorneys and counsel,  and all other expenses and liabilities
         incurred,  and all advances  made, by the Trustee except as a result of
         negligence or bad faith.

                  Nothing  herein  contained  shall be deemed to  authorize  the
Trustee to  authorize  or consent to or vote for or accept or adopt on behalf of
any Holder any plan of  reorganization,  arrangement,  adjustment or composition
affecting the Securities of any series 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  except, as aforesaid,  to vote for the election of a trustee in
bankruptcy or similar person.

                  All  rights of  action  and of  asserting  claims  under  this
Indenture,  or under any of the Securities of any series or Coupons appertaining
thereto, may be enforced by the Trustee

                                      -44-

<PAGE>



without  the  possession  of any of the  Securities  of such  series or  coupons
appertaining thereto or the production thereof on any trial or other proceedings
relative thereto,  and any such action or proceedings  instituted by the Trustee
shall be  brought  in its own  name as  trustee  of an  express  trust,  and any
recovery of judgment, subject to the payment of the expenses,  disbursements and
compensation of the Trustee and its agents,  attorneys and counsel, shall be for
the ratable benefit of the Holders of the Securities or Coupons  appertaining to
such Securities in respect of which such action was taken.

                  In any  proceedings  brought  by the  Trustee  (and  also  any
proceedings  involving the  interpretation of any provision of this Indenture to
which the Trustee  shall be a party) the Trustee  shall be held to represent all
the Holders of the  Securities  and Coupons  appertaining  thereto in respect to
which  action was taken,  and it shall not be  necessary  to make any Holders of
such Securities or Coupons parties to any such proceedings.

                  SECTION 5.3 Application of Proceeds.  Any moneys  collected by
the Trustee  pursuant to this Article in respect of the Securities of any series
shall be  applied  in the  following  order  at the  date or dates  fixed by the
Trustee and, in case of the  distribution of such moneys on account of principal
or  interest,   upon   presentation  of  the  several   Securities  and  Coupons
appertaining thereto in respect of which moneys have been collected and stamping
(or otherwise  noting)  thereon the payment,  or issuing  Securities of the same

only partially paid, or upon surrender thereof if fully paid:

                  FIRST:  To the  payment of costs and  expenses  of  collection
         applicable to such series,  including  reasonable  compensation  to the
         Trustee and its agents,  attorneys  and counsel and of all expenses and
         liabilities incurred, and all advances made, by the Trustee except as a
         result of negligence or bad faith;

                  SECOND: In case the principal of the Securities of such series
         in respect of which  moneys have been  collected  shall not have become
         and be  then  due  and  payable,  to the  payment  of  interest  on the
         Securities  of such  series in default in the order of the  maturity of
         the  installments  of such interest,  with interest (to the extent that
         such  interest  has been  collected  by the  Trustee)  upon the overdue
         installments  of interest at the same rate as the rate of interest  (or
         Yield to Maturity,  in the case of Original Issue Discount  Securities)
         specified in such  Securities,  such payments to be made ratably to the
         Persons entitled thereto, without discrimination or preference;

<PAGE>



                  THIRD:  In case the principal of the Securities of such series
         in respect of which moneys have been collected shall have become and be
         then due and payable, to the payment of the whole amount then owing and
         unpaid  upon  all the  Securities  of such  series  for  principal  and
         interest, with interest upon the overdue principal,  and (to the extent
         that such  interest has been  collected  by the  Trustee)  upon overdue
         installments  of interest at the same rate as the rate of interest  (or
         Yield to Maturity,  in the case of Original Issue Discount  Securities)
         specified in the  Securities  of such  series;  and in case such moneys
         shall be insufficient to pay in full the whole amount so due and unpaid
         upon  the  Securities  of  such  series,  then to the  payment  of such
         principal  and  interest,  without  preference or priority of principal
         over interest, or of interest over principal,  or of any installment of
         interest over any other installment of interest,  or of any Security of
         such series  over any other  Security  of such  series,  ratably to the
         aggregate of such principal and accrued and unpaid interest; and

                  FOURTH:  To the payment of the remainder, if any,
         to the Issuer or any other person lawfully entitled
         thereto.

                  SECTION 5.4 Suits for Enforcement. In case an Event of Default
has  occurred,  has not been  waived and is  continuing,  the Trustee may in its
discretion  proceed  to protect  and  enforce  the  rights  vested in it by this
Indenture by such  appropriate  judicial  proceedings  as the Trustee shall deem
most  effectual to protect and enforce any of such  rights,  either at law or in
equity or in bankruptcy or otherwise,  whether for the specific  enforcement  of
any covenant or agreement  contained in this Indenture or in aid of the exercise
of any  power  granted  in this  Indenture  or to  enforce  any  other  legal or
equitable right vested in the Trustee by this Indenture or by law.

                  SECTION  5.5   Restoration   of  Rights  on   Abandonment   of
Proceedings. In case the Trustee shall have proceeded to enforce any right under
this Indenture and such  proceedings  shall have been  discontinued or abandoned
for any reason,  or shall have been determined  adversely to the Trustee,  then,
and  in  every  such  case,  the  Issuer  and  the  Trustee  shall  be  restored
respectively  to their former  positions and rights  hereunder,  and all rights,
remedies  and powers of the Issuer,  the Trustee and the  Securityholders  shall
continue as though no such proceedings had been taken.

                  SECTION 5.6  Limitations on Suits by Securityholders.
No Holder of any Security of any series or of any Coupon

                                      -46-

<PAGE>



appertaining  thereto  shall  have any  right by virtue  or by  availing  of any
provision of this  Indenture to institute  any action or proceeding at law or in
equity or in  bankruptcy  or  otherwise  upon or under or with  respect  to this
Indenture, or for the appointment of a trustee, receiver, liquidator,  custodian
or other similar official or for any other remedy hereunder,  unless such Holder
previously  shall have given to the Trustee written notice of default and of the
continuance  thereof, as hereinbefore  provided,  and unless also the Holders of
not less  than 25% in  aggregate  principal  amount  of the  Securities  of each
affected  series  then  Outstanding  (determined  as provided in Section 5.1 and
voting as one  class)  shall  have made  written  request  upon the  Trustee  to
institute such action or  proceedings  in its own name as trustee  hereunder and
shall have  offered to the Trustee such  reasonable  indemnity as it may require
against the costs,  expenses and  liabilities to be incurred  therein or thereby
and the Trustee for 60 days after its receipt of such notice,  request and offer
of indemnity shall have failed to institute any such action or proceeding and no
direction  inconsistent  with such written  request shall have been given to the
Trustee  pursuant to Section 5.9; it being  understood  and intended,  and being
expressly  covenanted  by the taker and Holder of every  Security or Coupon with
every other  taker and Holder and the  Trustee,  that no one or more  Holders of
Securities of any series or Coupons appertaining thereto shall have any right in
any manner  whatever by virtue or by availing of any provision of this Indenture
to affect,  disturb or prejudice the rights of any other Holder of Securities or
Coupons  appertaining  thereto,  or to obtain or seek to obtain priority over or
preference  to any  other  such  Holder  or to  enforce  any  right  under  this
Indenture,  except in the manner herein provided and for the equal,  ratable and
common benefit of all Holders of Securities of the affected  series and Coupons.
For the protection and  enforcement of the provisions of this Section,  each and
every  Securityholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

                  SECTION  5.7  Unconditional   Right  of   Securityholders   to
Institute Certain Suits.  Notwithstanding  any other provision in this Indenture
and any  provision of any  Security,  the right of any Holder of any Security or
Coupon to receive  payment of the  principal of and interest on such Security or
Coupon on or after  the  respective  due dates  expressed  in such  Security  or
Coupon, or to institute suit for the enforcement of any such payment on or after
such respective dates,  shall not be impaired or affected without the consent of
such Holder.

                  SECTION 5.8 Powers and Remedies Cumulative;  Delay or Omission
Not Waiver of Default.  Except as  provided in the last  sentence of Section 2.9
and subject to Section 5.6, no right or remedy herein conferred upon or reserved
to the Trustee or to the

<PAGE>



Holders of  Securities or Coupons 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.

                  No  delay or  omission  of the  Trustee  or of any  Holder  of
Securities or Coupons to exercise any right or power  accruing upon any Event of
Default  occurring and  continuing  as aforesaid  shall impair any such right or
power or shall be  construed  to be a waiver of any such  Event of Default or an
acquiescence  therein; and, subject to Section 5.6, every power and remedy given
by this  Indenture or by law to the Trustee or to the Holders of  Securities  or
Coupons  may be  exercised  from  time to time,  and as often as shall be deemed
expedient, by the Trustee or by the Holders of Securities or Coupons.

                  SECTION 5.9 Control by Holders of Securities. The Holders of a
majority in aggregate principal amount of the Securities of each series affected
at the time Outstanding (determined as provided in Section 5.1 and voting as one
class) 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  upon the Trustee  with  respect to the  Securities  of such
affected  series by this  Indenture;  provided that such direction  shall not be
otherwise  than in accordance  with law and the provisions of this Indenture and
provided  further that  (subject to the  provisions  of Section 6.1) the Trustee
shall have the right to decline to follow  any such  direction  if the  Trustee,
being  advised by counsel,  shall  determine  that the action or  proceeding  so
directed  may not lawfully be taken or if the Trustee in good faith by its board
of  directors,  its  executive  committee  or a trust  committee of directors or
Responsible  Officers  of  the  Trustee  shall  determine  that  the  action  or
proceedings so directed would involve the Trustee in personal  liability or that
the actions or forbearances  specified in or pursuant to such direction would be
unduly prejudicial to the interests of Holders of the Securities of all affected
series not joining in the giving of said  direction,  it being  understood  that
(subject to Section 6.1) the Trustee shall have no duty to ascertain  whether or
not such actions or forbearances are unduly prejudicial to such Holders.

                  Nothing  in this  Indenture  shall  impair  the  right  of the
Trustee in its  discretion  to take any action  deemed proper by the Trustee and
which is not inconsistent with such direction or directions by Securityholders.

                  SECTION 5.10 Waiver of Past Defaults. Prior to the declaration
of  acceleration  of the maturity of any  Securities as provided in Section 5.1,
the Holders of a majority in aggregate principal amount of the Securities of all
series at the time  Outstanding  with  respect to which a default or an Event of
Default shall have occurred and be continuing (determined as provided in Section
5.1 and voting as one class) may on behalf of the  Holders of all such  affected
Securities  waive any past  default  or Event of  Default  with  respect to such
series  described  in Section 5.1 and its  consequences,  except a default or an
Event of Default in respect of a covenant or provision hereof or of any Security
which  cannot be modified  or amended  without the consent of the Holder of each
Security  affected.  In the case of any such waiver, the Issuer, the Trustee and
the Holders of all such  affected  Securities  shall be restored to their former
positions and rights hereunder, respectively; but no such waiver shall extend to
any subsequent or other default or impair any right consequent thereon.

                  Upon any such waiver, such default shall cease to exist and be
deemed to have been  cured and not to have  occurred,  and any Event of  Default
arising  therefrom shall be deemed to have been cured,  and not to have occurred
for every  purpose of this  Indenture;  but no such waiver  shall  extend to any
subsequent or other  default or Event of Default or impair any right  consequent
thereon.

                  SECTION  5.11  Trustee  to Give  Notice  of  Default,  But May
Withhold in Certain  Circumstances.  The Trustee shall, within 90 days after the
occurrence  of a default  with  respect to the  Securities  of any series,  give
notice of all  defaults  with respect to such series known to the Trustee (i) if
any Unregistered Securities of such series are then Outstanding,  to the Holders
thereof by publication at least once in each  Authorized  Newspaper with respect
to such  series and (ii) to all  Holders  of  Securities  of such  series in the
manner and to the extent  provided in Section  4.4(c),  unless in each case such
defaults  shall have been cured before the mailing or publication of such notice
(the term "default" for the purpose of this Article being hereby defined to mean
any event or  condition  which is, or with notice or lapse of time or both would
become,  an Event of Default);  provided that,  except in the case of default in
the payment of the principal of or the interest on any of the Securities of such
series,  or in the payment of any sinking fund installment or analogous  payment
on such series, the Trustee shall be protected in withholding such notice if and
so long as the board of directors,  the executive committee or a trust committee
of  directors  or trustees  and/or  Responsible  Officers of the Trustee in good
faith  determines that the withholding of such notice is in the interests of the
Securityholders of such series.

                  SECTION 5.12 Right of Court to Require  Filing of  Undertaking
to Pay  Costs.  All  parties to this  Indenture  agree,  and each  Holder of any
Security or Coupon by his  acceptance  thereof  shall be deemed to have  agreed,
that any court may in its discretion require, in any suit for the enforcement of
any right or remedy under this  Indenture or in any suit against the Trustee for
any action taken,  suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an  undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs,  including  reasonable
attorneys' fees,  against any party litigant in such suit,  having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Trustee,   to  any  suit   instituted   by  any   Securityholder   or  group  of
Securityholders  of  any  series  holding  in the  aggregate  more  than  10% in
aggregate  principal amount of the Securities of such series, or, in the case of
any suit  relating to or arising  under clause (d) or (g) of Section 5.1 (if the
suit relates to the  Securities of more than one but less than all series),  10%
in aggregate  principal  amount of the Securities then  outstanding and affected
thereby,  or, in the case of any suit relating to or arising under clause (d) or
(g) (if the suit relates to all the Securities then Outstanding),  or clause (e)
or (f) of Section 5.1, 10% in aggregate  principal amount of all Securities then
Outstanding, or to any suit instituted by any Securityholder for the enforcement
of the payment of the principal of or the interest (including interest evidenced
by any  Coupon)  on any  Security  on or after  the due date  expressed  in such
Security or Coupon or any date fixed for redemption.


                                   ARTICLE SIX

                             CONCERNING THE TRUSTEE
                             ----------------------

                  SECTION 6.1 Duties and Responsibilities of the Trustee; During
Default;  Prior to Default. The Trustee,  prior to the occurrence of an Event of
Default with  respect to the  Securities  of a  particular  series and after the
curing or waiving of all Events of Default  which may have occurred with respect
to such  series,  undertakes  to perform such duties and only such duties as are
specifically  set  forth in this  Indenture.  In case an Event of  Default  with
respect to the  Securities  of a particular  series has occurred  (which has not
been cured or waived),  the Trustee  shall  exercise with respect to such series
such of the rights and powers vested in it by this  Indenture,  and use the same
degree of care and skill in their  exercise,  as a prudent man would exercise or
use under the circumstances in the conduct of his own affairs.

                  No provision of this  Indenture  shall be construed to relieve
the Trustee from  liability  for its own  negligent  action,  its own  negligent
failure to act or its own wilful misconduct, except that

                  (a)  prior  to the  occurrence  of an Event  of  Default  with
         respect to the Securities of any series and after the curing or waiving
         of all such Events of Default  which may have  occurred with respect to
         such series:

                           (i) the duties and  obligations  of the Trustee  with
                  respect to the  Securities  of such series shall be determined
                  solely by the express  provisions of this  Indenture,  and the
                  Trustee shall not be liable except for the performance of such
                  duties and obligations 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 the part of the
                  Trustee, the Trustee may conclusively rely, as to the truth of
                  the statements and the  correctness of the opinions  expressed
                  therein,   upon  any  statements,   certificates  or  opinions
                  furnished to the Trustee and conforming to the requirements of
                  this  Indenture;  but in the  case  of  any  such  statements,
                  certificates  or opinions  which by any  provision  hereof are
                  specifically  required to be  furnished  to the  Trustee,  the
                  Trustee shall be under a duty to examine the same to determine
                  whether  or not  they  conform  to the  requirements  of  this
                  Indenture;

                  (b) the Trustee  shall not be liable for any error of judgment
         made in good faith by a Responsible Officer or Responsible  Officers of
         the Trustee,  unless it shall be proved that the Trustee was  negligent
         in ascertaining the pertinent facts; and

                  (c) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance  with an
         appropriate  direction of the Holders  pursuant to Section 5.9 relating
         to the time,  method and place of  conducting  any  proceeding  for any
         remedy  available  to the  Trustee,  or  exercising  any trust or power
         conferred upon the Trustee, under this Indenture.

                  None  of the  provisions  contained  in this  Indenture  shall
require the Trustee to expend or risk its own funds or otherwise  incur personal
financial  liability in the  performance of any of its duties or in the exercise
of any of its  rights  or  powers,  if there  shall be  reasonable  grounds  for
believing  that the repayment of such funds or adequate  indemnity  against such
liability is not reasonably assured to it.

                  SECTION 6.2 Certain Rights of the Trustee.  Subject to Section
6.1:

                  (a) the Trustee may rely and shall be  protected  in acting or
         refraining  from acting upon any resolution,  Officers'  Certificate or
         other certificate,  statement,  instrument,  opinion,  report,  notice,
         request,  consent,  order, bond, debenture,  note, Coupon,  security or
         other paper or  document  believed by it to be genuine and to have been
         signed or presented by the proper party or parties;

                  (b) any  request,  direction,  order or demand  of the  Issuer
         mentioned  herein  shall  be  sufficiently  evidenced  by an  Officers'
         Certificate  (unless  other  evidence  in  respect  thereof  be  herein
         specifically prescribed);  and any resolution of the Board of Directors
         may be  evidenced  to the Trustee by a copy  thereof  certified  by the
         secretary or an assistant secretary of the Issuer;

                  (c) the  Trustee  may  consult  with  counsel  and any written
         advice  or  any  Opinion  of  Counsel   shall  be  full  and   complete
         authorization  and protection in respect of any action taken,  suffered
         or omitted to be taken by it hereunder in good faith and in  accordance
         with such advice or Opinion of Counsel;

                  (d) the Trustee  shall be under no  obligation to exercise any
         of the trusts or powers vested in it by this  Indenture at the request,
         order or direction of any of the Holders  pursuant to the provisions of
         this  Indenture,  unless such Holders shall have offered to the Trustee
         reasonable indemnity against the costs,  expenses and liabilities which
         might be incurred therein or thereby;

                  (e) the  Trustee  shall not be liable for any action  taken or
         omitted  by it in good faith and  believed  by it to be  authorized  or
         within  the  discretion,  rights  or powers  conferred  upon it by this
         Indenture;

                                      -52-

<PAGE>



                  (f)  prior  to the  occurrence  of an Event  of  Default  with
         respect to the Securities of any series and after the curing or waiving
         of all such Events of Default,  the Trustee  shall not be bound to make
         any  investigation  into the facts or matters stated in any resolution,
         certificate,  statement,  instrument, opinion, report, notice, request,
         consent,  order, approval,  appraisal,  bond, debenture,  note, Coupon,
         security or other paper or document  unless  requested in writing so to
         do by the  Holders of not less than a majority in  aggregate  principal
         amount of the  Securities  of all  affected  series  then  Outstanding;
         provided that, if the payment  within a reasonable  time to the Trustee
         of the costs,  expenses or  liabilities  likely to be incurred by it in
         the making of such investigation is, in the opinion of the Trustee, not
         reasonably assured to the Trustee by the security afforded to it by the
         terms of this Indenture,  the Trustee may require reasonable  indemnity
         against  such  costs,   expenses  or  liabilities  as  a  condition  to
         proceeding;  the reasonable  expenses of every such investigation shall
         be paid by the  Issuer or, if paid by the  Trustee,  shall be repaid by
         the Issuer upon demand; and

                  (g) the  Trustee  may  execute  any of the  trusts  or  powers
         hereunder  or perform  any duties  hereunder  either  directly or by or
         through  agents or  attorneys  not  regularly  in its  employ,  and the
         Trustee shall not be  responsible  for any  misconduct or negligence on
         the part of any such agent or  attorney  appointed  with due care by it
         hereunder.

                  SECTION 6.3 Trustee Not Responsible for Recitals,  Disposition
of Securities or Application of Proceeds Thereof.  The recitals contained herein
and in the  Securities,  except the Trustee's  certificates  of  authentication,
shall be taken as the  statements  of the  Issuer,  and the  Trustee  assumes no
responsibility   for  the   correctness  of  the  same.  The  Trustee  makes  no
representation  as to the validity or  sufficiency  of this  Indenture or of the
Securities  or Coupons.  The  Trustee  shall not be  accountable  for the use or
application by the Issuer of any of the Securities or of the proceeds thereof.

                  SECTION 6.4 Trustee and Agents May Hold Securities or Coupons;
Collections,  etc. The Trustee or any agent of the Issuer or the Trustee, in its
individual or any other capacity,  may become the owner or pledgee of Securities
or Coupons with the same rights it would have if it were not the Trustee or such
agent and,  subject to Sections 6.8 and 6.13, may otherwise deal with the Issuer
and receive, collect, hold and retain collections

                                      -53-

<PAGE>



from the Issuer with the same rights it would have if it were not the Trustee or
such agent.

                  SECTION 6.5 Moneys Held by Trustee.  Subject to the provisions
of Section 10.4, all moneys received by the Trustee shall, until used or applied
as herein  provided,  be held in trust  for the  purposes  for  which  they were
received,  but need not be  segregated  from  other  funds  except to the extent
required by mandatory  provisions  of law.  Neither the Trustee nor any agent of
the Issuer or the  Trustee  shall be under any  liability  for  interest  on any
moneys received by it hereunder.

                  SECTION 6.6  Compensation and  Indemnification  of Trustee and
Its Prior Claim. The Issuer covenants and agrees to pay to the Trustee from time
to time, and the Trustee shall be entitled to,  reasonable  compensation  (which
shall not be limited by any provision of law in regard to the  compensation of a
trustee of an express  trust),  and the  Issuer  covenants  and agrees to pay or
reimburse   the  Trustee   upon  its  request  for  all   reasonable   expenses,
disbursements  and advances incurred or made by or on behalf of it in accordance
with  any  of  the  provisions  of  this  Indenture  (including  the  reasonable
compensation and the expenses and disbursements of its counsel and of all agents
and  other  persons  not  regularly  in its  employ)  except  any such  expense,
disbursement  or  advance  as may arise from its  negligence  or bad faith.  The
Issuer also  covenants  to  indemnify  the Trustee  for, and to hold it harmless
against, any loss, liability or expense incurred without negligence or bad faith
on  its  part  arising  out  of  or  in  connection   with  the   acceptance  or
administration  of  this  Indenture  or the  trusts  hereunder  and  its  duties
hereunder,  including  the costs and  expenses of  defending  itself  against or
investigating  any claim or liability in the premises.  The  obligations  of the
Issuer under this Section to compensate  and indemnify the Trustee and to pay or
reimburse the Trustee for expenses,  disbursements and advances shall constitute
additional  indebtedness  hereunder  and  shall  survive  the  satisfaction  and
discharge of this  Indenture.  Such  additional  indebtedness  shall be a senior
claim to that of the Securities upon all property and funds held or collected by
the Trustee as such,  except  funds held in trust for the benefit of the Holders
of particular  Securities or Coupons, and the Securities are hereby subordinated
to such senior claim.

                  SECTION 6.7 Right of Trustee to Rely on Officers' Certificate,
etc.  Subject to Sections  6.1 and 6.2,  whenever in the  administration  of the
trusts of this Indenture the Trustee shall deem it necessary or desirable that a
matter be proved or  established  prior to taking or  suffering  or omitting any
action  hereunder,  such matter  (unless  other  evidence in respect  thereof be
herein  specifically  prescribed) may, in the absence of negligence or bad faith
on the part of the Trustee, be deemed to

                                      -54-

<PAGE>



be conclusively proved and established by an Officers'  Certificate delivered to
the Trustee, and such certificate,  in the absence of negligence or bad faith on
the part of the  Trustee,  shall be full  warrant to the  Trustee for any action
taken,  suffered  or omitted by it under the  provisions  of this  Indenture  in
reliance thereon.

                  SECTION 6.8 Qualification of Trustee;  Conflicting  Interests.
The Trustee shall be disqualified only where such  disqualification  is required
by Section 310(b) of the Trust Indenture Act.  Nothing shall prevent the Trustee
from filing with the  Commission  the  application  referred to in the second to
last paragraph of Section 310(b) of the Trust Indenture Act.

                  SECTION 6.9 Persons Eligible for Appointment as Trustee. There
shall at all times be a Trustee  hereunder for each series of  Securities  which
shall be a corporation organized and doing business under the laws of the United
States of America or of any State  thereof or the District of Columbia  having a
combined  capital and surplus of at least  $50,000,000,  and which is authorized
under such laws to exercise corporate trust powers and is subject to supervision
or  examination  by Federal,  State or District of Columbia  authority.  If such
corporation 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,  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.  In case at any time the
Trustee  shall cease to be eligible in  accordance  with the  provisions of this
Section,  the Trustee shall resign immediately in the manner and with the effect
specified in Section 6.10.

                  SECTION 6.10 Resignation and Removal; Appointment of Successor
Trustee. (a) The Trustee, or any trustee or trustees hereafter appointed, may at
any time  resign  with  respect  to one or more or all series of  Securities  by
giving written  notice of resignation to the Issuer and (i) if any  Unregistered
Securities of a series affected are then  Outstanding,  by giving notice of such
resignation  to the  Holders  thereof  by  publication  at  least  once  in each
Authorized  Newspaper  with  respect to such  series,  (ii) if any  Unregistered
Securities of a series affected are then Outstanding,  by mailing notice of such
resignation to the Holders thereof who have filed their names and addresses with
the  Trustee  pursuant  to  Section  4.4(c)(ii)  at  such  addresses  as were so
furnished to the Trustee and (iii) by mailing notice of such  resignation to the
Holders of the then Outstanding Registered Securities of each series affected at
their  addresses as they shall appear on the Security  Register.  Upon receiving
such  notice of  resignation,  the Issuer  shall  promptly  appoint a  successor
trustee or trustees with respect to the applicable

                                      -55-

<PAGE>



series by written instrument,  in duplicate,  executed by authority of the Board
of Directors,  one copy of which  instrument shall be delivered to the resigning
Trustee  and one copy to the  successor  trustee or  trustees.  If no  successor
trustee  shall have been so appointed  with respect to any series and shall have
accepted  appointment  within  30 days  after  the  mailing  of such  notice  of
resignation,   the  resigning  trustee  may  petition  any  court  of  competent
jurisdiction for the appointment of a successor  trustee,  or any Holder who has
been a bona fide Holder of a Security or  Securities of such series for at least
six months may,  subject to the  provisions  of Section  5.12, on behalf of such
Holder  and all  others  similarly  situated,  petition  any such  court for the
appointment of a successor trustee. Such court may thereupon, after such notice,
if any, as it may deem proper and prescribe, appoint a successor trustee.

                   (b)  In case at any time any of the following shall occur:

                   (i) the Trustee  shall fail to comply with the  provisions of
         Section  6.8 with  respect to any series of  Securities  after  written
         request  therefor  by the  Issuer or by any  Holder who has been a bona
         fide Holder of a Security or Securities of such series for at least six
         months; or

                  (ii) the Trustee shall cease to be eligible in accordance with
         the  provisions  of Section 6.9 and shall fail to resign after  written
         request therefor by the Issuer or by any such Holder; or

                  (iii) the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or  insolvent,  or a receiver or  liquidator of the
         Trustee or of its property  shall be appointed,  or any public  officer
         shall  take  charge or control of the  Trustee  or of its  property  or
         affairs for the purpose of rehabilitation, conservation or liquidation;
         or

                   (iv) the Issuer shall elect to remove the  Trustee,  provided
         that no Event  of  Default,  or event  which  following  notice  or the
         passage of time or both would  constitute  an Event of  Default,  shall
         then exist with respect to the Securities or series thereof as to which
         the Trustee shall be removed and such removal does not adversely affect
         the interests of any Holder of such Securities or series;

then,  in any such case,  the Issuer may remove the Trustee  with respect to the
Securities of any or all series, as appropriate, and appoint a successor trustee
for such series by written

                                      -56-

<PAGE>



instrument, in duplicate,  executed by order of the Board of Directors, one copy
of which instrument shall be delivered to the Trustee so removed and one copy to
the  successor  trustee or trustees,  or,  subject to the  provisions of Section
5.12,  any Holder who has been a bona fide Holder of a Security or Securities of
such series 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.  Such court may
thereupon,  after such  notice,  if any,  as it may deem  proper and  prescribe,
remove the Trustee and appoint a successor trustee.

                  (c) Any  resignation or removal of the Trustee with respect to
any series of Securities and any appointment of a successor trustee with respect
to such series  pursuant to any of the  provisions  of this Section shall become
effective upon acceptance of appointment by the successor trustee as provided in
Section 6.11.

                  SECTION 6.11  Acceptance of Appointment by Successor  Trustee.
Any  successor  trustee  appointed  as provided in Section  6.10 shall  execute,
acknowledge  and  deliver  to  the  Issuer  and to its  predecessor  trustee  an
instrument accepting such appointment  hereunder,  and thereupon the resignation
or removal of the predecessor  trustee with respect to all applicable  series of
Securities  shall  become  effective  and such  successor  trustee,  without any
further act, deed or  conveyance,  shall become vested with all rights,  powers,
trusts and duties  with  respect to such  applicable  series of its  predecessor
hereunder,  with like effect as if  originally  named as trustee for such series
hereunder;  but,  nevertheless,  on the written  request of the Issuer or of the
successor trustee,  upon payment of its charges then unpaid, the trustee ceasing
to act shall,  subject to Section 10.4,  pay over to the  successor  trustee all
moneys at the time  held by it  hereunder  for the  benefit  of such  applicable
series and shall execute,  acknowledge and deliver an instrument transferring to
such successor trustee all such rights,  powers, trusts and duties. Upon request
of any such successor trustee,  the Issuer shall execute and acknowledge any and
all  instruments  in  writing  for  more  fully  and  certainly  vesting  in and
confirming to such  successor  trustee all such rights,  powers and trusts.  Any
trustee  ceasing  to act  shall,  nevertheless,  retain a prior  claim  upon all
property  or funds held or  collected  by such  trustee  for the benefit of such
applicable  series to secure any amounts then due it pursuant to the  provisions
of Section 6.6.

                  If a  successor  trustee  is  appointed  with  respect  to the
Securities  of one  or  more  (but  less  than  all)  series,  the  Issuer,  the
predecessor  trustee and each  successor  trustee so  appointed  shall  execute,
acknowledge  and deliver an indenture  supplemental  hereto which shall  contain
such provisions as shall be deemed

                                      -57-

<PAGE>



necessary or desirable to confirm that all the rights, powers, trusts and duties
of such  predecessor  trustee with respect to the Securities of any series as to
which such  predecessor  trustee is not retiring  shall continue to be vested in
such predecessor  trustee, and to add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the  administration
of the trusts  hereunder  by more than one  trustee,  it being  understood  that
nothing herein or in such supplemental  indenture shall constitute such trustees
as  co-trustees of the same trust and that each such trustee shall be trustee of
a separate trust or trusts under this indenture.

                  No successor  trustee with respect to any series of Securities
shall accept  appointment as provided in this Section unless at the time of such
acceptance  such  successor  trustee shall be qualified  under the provisions of
Section 6.8 and eligible under the provisions of Section 6.9.

                  Upon  acceptance of  appointment  by any successor  trustee as
provided  in this  Section,  the Issuer  shall give  notice  thereof  (a) if any
Unregistered  Securities  of a  series  affected  are then  Outstanding,  to the
Holders  thereof by publication of such notice at least once in each  Authorized
Newspaper with respect to such series,  (b) if any Unregistered  Securities of a
series  affected  are then  Outstanding,  to the Holders  thereof who have filed
their names and  addresses  with the Trustee  pursuant to Section  4.4(c)(ii) by
mailing  such notice to such  Holders at such  addresses as were so furnished to
the Trustee (and the Trustee shall make such information available to the Issuer
for such purpose) and (c) to the Holders of Registered Securities of each series
affected,  by mailing  such notice to such  Holders at their  addresses  as they
shall appear on the Security  Register.  If the  acceptance  of  appointment  is
substantially  contemporaneous with the resignation,  then the notice called for
by the preceding  sentence may be combined with the notice called for by Section
6.10. If the Issuer fails to give such notice within 10 days after acceptance of
appointment  by the successor  trustee,  the successor  trustee shall cause such
notice to be given at the expense of the Issuer.

                  SECTION 6.12 Merger,  Conversion,  Consolidation or Succession
to Business of Trustee.  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 the corporate  trust  business of the
Trustee,  shall be the  successor of the Trustee  hereunder,  provided that such
corporation  shall be qualified under the provisions of Section 6.8 and eligible
under the provisions of Section 6.9, without the execution or filing of any

                                      -58-

<PAGE>



paper or any further act on the part of any of the parties hereto, anything 
herein to the contrary notwithstanding.

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

                  SECTION 6.13  Preferential  Collection  of Claims  Against the
Issuer.  (a) Subject to the provisions of this Section,  if the Trustee shall be
or shall become a creditor, directly or indirectly, secured or unsecured, of the
Issuer within three months prior to a default,  as defined in subsection  (c) of
this  Section,  or  subsequent  to such a default,  then,  unless and until such
default  shall be  cured,  the  Trustee  shall  set  apart and hold in a special
account  for  the  benefit  of the  Trustee  individually,  the  Holders  of the
Securities and Coupons and the holders of other indenture securities (as defined
in such subsection (c)):

                  (1) an amount  equal to any and all  reductions  in the amount
         due and owing upon any claim as such  creditor in respect of  principal
         or interest  affected  after the beginning of such three months' period
         and valid as against  the Issuer  and its other  creditors,  except any
         such  reduction  resulting  from  the  receipt  or  disposition  of any
         property  described  in  clause  (2) of this  subsection,  or from  the
         exercise of any right of set-off which the Trustee could have exercised
         if a petition  in  bankruptcy  had been filed by or against  the Issuer
         upon the date of such default; and

                  (2) all  property  received  by the  Trustee in respect of any
         claim as such creditor, either as security therefor, or in satisfaction
         or composition thereof, or otherwise, after the beginning of such three
         months' period, or an amount equal to the proceeds of any such property
         if disposed of, subject,  however, to the rights, if any, of the Issuer
         and its other creditors in such property or such proceeds.


                                      -59-

                  Nothing herein contained,  however,  shall affect the right of
the Trustee:

                  (A) to retain for its own account (i) payments made on account
         of any such claim by any person  (other  than the Issuer) who is liable
         thereon,  (ii) the  proceeds of the bona fide sale of any such claim by
         the Trustee to a third person,  and (iii)  distributions  made in cash,
         securities  or other  property in respect of claims  filed  against the
         Issuer  in   bankruptcy  or   receivership   or  in   proceedings   for
         reorganization  pursuant  to  Title  11 of the  United  States  Code or
         applicable state law;

                  (B) to realize, for its own account, upon any property held by
         it as security for any such claim,  if such  property was so held prior
         to the beginning of such three months' period;

                  (C) to realize, for its own account, but only to the extent of
         the  claim  hereinafter  mentioned,  upon  any  property  held by it as
         security  for any such  claim,  if such  claim  was  created  after the
         beginning of such three  months'  period and such property was received
         as security therefor  simultaneously with the creation thereof,  and if
         the Trustee  shall  sustain the burden of proving that at the time such
         property was so received the Trustee had no reasonable cause to believe
         that a default as defined in subsection (c) of this Section would occur
         within three months; or

                  (D) to receive  payment on any claim referred to in clause (B)
         or (C) of this subsection,  against the release of any property held as
         security  for such claim as  provided in such clause (B) or (C), as the
         case may be, to the extent of the fair value of such property,

                  For  the  purposes  of  clauses  (B),  (C) and  (D),  property
substituted  after the beginning of such three months'  period for property held
as security at the time of such  substitution  shall,  to the extent of the fair
value of the property  released,  have the same status as the property released,
and, to the extent that any claim  referred to in any of such clauses is created
in renewal of or in substitution for or for the purpose of repaying or refunding
any  pre-existing  claim of the Trustee as such creditor,  such claim shall have
the same status as such pre-existing claim.

                  If the Trustee  shall be  required  to account,  the funds and
property  held  in such  special  account  and the  proceeds  thereof  shall  be
apportioned  among the Trustee,  the Holders and the holders of other  indenture
securities in such manner that the Trustee, the Holders and the holders of other
indenture

                                      -60-

<PAGE>



securities  realize,  as a result of  payments  from such  special  account  and
payments  of  dividends  on claims  filed  against the Issuer in  bankruptcy  or
receivership  or in proceedings for  reorganization  pursuant to Title 11 of the
United  States  Code or  applicable  State  law,  the same  percentage  of their
respective claims, figured before crediting to the claim of the Trustee anything
on account of the  receipt  by it from the Issuer of the funds and  property  in
such  special  account  and before  crediting  to the  respective  claims of the
Trustee,  the Holders and the holders of other indenture securities dividends on
claims filed against the Issuer in bankruptcy or  receivership or in proceedings
for reorganization  pursuant to Title 11 of the United States Code or applicable
State law, but after crediting  thereon  receipts on account of the indebtedness
represented  by their  respective  claims from all sources  other than from such
dividends  and from the funds and property so held in such special  account.  As
used in this paragraph  with respect to any claim,  the term  "dividends"  shall
include  any  distribution   with  respect  to  such  claim,  in  bankruptcy  or
receivership  or in proceedings for  reorganization  pursuant to Title 11 of the
United States Code or applicable State law, whether such distribution is made in
cash, securities or other property,  but shall not include any such distribution
with respect to the secured  portion,  if any, of such claim. The court in which
such bankruptcy,  receivership or proceeding for reorganization is pending shall
have  jurisdiction  (i) to  apportion  among the  Trustee,  the  Holders and the
holders of other indenture securities, in accordance with the provisions of this
paragraph,  the funds and property held in such special account and the proceeds
thereof, or (ii) in lieu of such apportionment,  in whole or in part, to give to
the provisions of this paragraph due  consideration  in determining the fairness
of the  distributions to be made to the Trustee,  the Holders and the holders of
other indenture  securities with respect to their  respective  claims,  in which
event it shall not be  necessary  to  liquidate  or to appraise the value of any
securities or other property held in such special account or as security for any
such claim, or to make a specific  allocation of such  distributions  as between
the secured and  unsecured  portions of such  claims,  or otherwise to apply the
provisions of this paragraph as a mathematical formula.

                  Any  Trustee  who has  resigned  or  been  removed  after  the
beginning of such  three-months'  period shall be subject to the  provisions  of
this subsection as though such  resignation or removal had not occurred.  If any
Trustee  has  resigned  or  been  removed   prior  to  the   beginning  of  such
three-months'  period,  it shall be subject to the provisions of this subsection
if and only if the following conditions exist:

                  (i)      the receipt of property or reduction of claim
         which would have given rise to the obligation to account, if

                                      -61-

<PAGE>



         such Trustee had continued as trustee, occurred after the beginning of
         such three-months' period; and

                  (ii) such receipt of property or  reduction of claim  occurred
         within three months after such resignation or removal.

                  (b)      There shall be excluded from the operation of this
         Section a creditor relationship arising from:

                           (1)  ownership or acquisition of securities issued
         under any indenture or any security or securities having a maturity
         of one year or more at the time of acquisition by the Trustee;

                           (2)  advances   authorized  by  a   receivership   or
         bankruptcy court of competent jurisdiction or by this Indenture for the
         purpose of preserving any property which shall at anytime be subject to
         the lien of this Indenture or of  discharging  tax liens or other prior
         liens or  encumbrances  thereon,  if notice of such  advance and of the
         circumstances   surrounding   the  making   thereof  is  given  to  the
         Securityholders  at the  time  and  in  the  manner  provided  in  this
         Indenture;

                           (3)  disbursements  made in the  ordinary  course  of
         business in the capacity of trustee under an indenture, transfer agent,
         registrar,  custodian,  paying agent,  fiscal agent or  depositary,  or
         other similar capacity;

                           (4) an  indebtedness  created as a result of services
         rendered or premises rented or an  indebtedness  created as a result of
         goods or securities sold in a cash transaction as defined in subsection
         (c)(3) of this Section;

                           (5) the ownership of stock or of other  securities of
         a corporation  organized  under the  provisions of Section 25(a) of the
         Federal  Reserve  Act, as amended,  which is directly or  indirectly  a
         creditor of the Issuer; or

                           (6)  the   acquisition,   ownership,   acceptance  or
         negotiation   of  any  drafts,   bills  of  exchange,   acceptances  or
         obligations which fall within the  classification  of  self-liquidating
         paper as defined in subsection (c)(4) of this Section.

                  (c)      As used in this Section:

                           (1) the term "default" shall mean any failure to make
         payment  in  full  of the  principal  of or  interest  upon  any of the
         Securities or upon the other indenture securities

                                      -62-

<PAGE>



         when and as such principal or interest becomes due and payable;

                           (2) the term "other indenture  securities" shall mean
         securities upon which the Issuer is an obligor (as defined in the Trust
         Indenture Act of 1939)  outstanding under any other indenture (i) under
         which the  Trustee  is also  trustee,  (ii) which  contains  provisions
         substantially  similar  to the  provisions  of  subsection  (a) of this
         Section  and  (iii)  under  which a  default  exists at the time of the
         apportionment of the funds and property held in said special account;

                           (3)  the  term  "cash  transaction"  shall  mean  any
         transaction in which full payment for goods or securities  sold is made
         within seven days after delivery of the goods or securities in currency
         or in checks or other  orders  drawn upon banks or bankers  and payable
         upon demand;

                           (4) the term "self-liquidating  paper" shall mean any
         draft, bill of exchange, acceptance or obligation which is made, drawn,
         negotiated  or incurred by the Issuer for the purpose of financing  the
         purchase, processing,  manufacture, shipment, storage or sale of goods,
         wares or merchandise and which is secured by documents evidencing title
         to,  possession of, or a lien upon, the goods,  wares or merchandise or
         the receivables or proceeds  arising from the sale of the goods,  wares
         or  merchandise  previously  constituting  the  security,  provided the
         security is received by the Trustee simultaneously with the creation of
         the  creditor  relationship  with the Issuer  arising  from the making,
         drawing,  negotiating  or  incurring  of the draft,  bill of  exchange,
         acceptance or obligation; and

                           (5)   the term "Issuer" shall mean any obligor upon
         the Securities.

                  SECTION 6.14  Appointment of Authenticating Agent.  As
long as any Securities of a series remain Outstanding, the Trustee may, by
an instrument in writing, appoint with the approval of the Issuer an 
authenticating agent (the "Authenticating Agent") which shall be authorized
to act on behalf of, but subject to the direction of, the Trustee to
authenticate Securities of such series, including Securities issued upon 
exchange, registration of transfer, partial redemption or pursuant to Section
2.9.   Securities of such series so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee.  Whenever reference is made in
this Indenture to the authentication and delivery of Securities of any series
by the Trustee or to the Trustee's certificate of

                                      -63-

<PAGE>



authentication,  such reference  shall be deemed to include  authentication  and
delivery on behalf of the Trustee by an Authenticating Agent for such series and
a certificate of authentication executed on behalf of the Trustee by such Authen
ticating Agent.  Such  Authenticating  Agent shall at all times be a corporation
organized and doing  business  under the laws of the United States of America or
of any State thereof or of the District of Columbia  authorized  under such laws
to exercise corporate trust powers,  having a combined capital and surplus of at
least  $5,000,000  (determined  as provided  in Section 6.9 with  respect to the
Trustee)  and  subject  to  supervision  or  examination  by  Federal  or  State
authority.

                  Any  corporation  into which any  Authenticating  Agent may be
merged or converted  or with which it may be  consolidated,  or any  corporation
resulting   from  any  merger,   conversion  or   consolidation   to  which  any
Authenticating  Agent shall be a party,  or any  corporation  succeeding  to the
corporate agency or corporate trust business of any Authenticating  Agent, shall
be the  successor  to such  Authenticating  Agent with  respect to all series of
Securities for which it served as Authenticating  Agent without the execution or
filing  of any  paper  or any  further  act on the part of the  Trustee  or such
Authenticating Agent.

                  Any  Authenticating  Agent  may at any  time,  and if it shall
cease to be  eligible  hereunder  shall,  resign  by  giving  written  notice of
resignation  to the  Trustee  and to the  Issuer.  The  Trustee  may at any time
terminate  the  agency  of any  Authenticating  Agent by giving  written  notice
thereof to such  Authenticating  Agent and the  Issuer.  Upon  receiving  such a
notice of  resignation  or upon such a  termination,  or in case at any time any
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions  of this  Section,  the Trustee shall upon receipt of an Issuer Order
appoint  a  successor  Authenticating  Agent and  shall  provide  notice of such
appointment to all Holders of Securities  affected  thereby in the manner and to
the  extent  provided  in Section  6.11 with  respect  to the  appointment  of a
successor  trustee.  Any successor  Authenticating  Agent upon acceptance of its
appointment  hereunder shall become vested with all rights, powers and duties of
its  predecessor  hereunder,  with  like  effect  as if  originally  named as an
Authenticating Agent.

                  Sections  6.2,  6.3,  6.4,  6.6 (except for the last  sentence
thereof) and 7.3 shall be applicable to any Authenticating Agent.

                                  ARTICLE SEVEN

                         CONCERNING THE SECURITYHOLDERS
                         ------------------------------

                  SECTION 7.1 Evidence of Action Taken by  Securityholders.  Any
request,  demand,  authorization,  direction,  notice,  consent, waiver or other
action provided by this Indenture to be given or taken by a specified percentage
in  aggregate  principal  amount of the  Holders  of one or more  series  may be
evidenced by one or more  instruments of  substantially  similar tenor signed by
such  specified  percentage  of  Holders  in  person  or by agent or proxy  duly
appointed in writing;  and, except as herein otherwise expressly provided,  such
action shall become  effective when such instrument or instruments are delivered
to the Trustee.

                  SECTION 7.2 Proof of Execution of  Instruments  and of Holding
of  Securities.  Subject to Sections 6.1 and 6.2,  proof of the execution of any
instrument  by a Holder or his  agent or proxy  shall be  sufficient  if made in
accordance  with such  reasonable  rules and regulations as may be prescribed by
the Trustee or in such manner as shall be satisfactory  to the Trustee.  Subject
to  Sections  6.1 and 6.2,  proof of the  holding  by any  Person  of any of the
Securities of any series shall be sufficient if made in the following manner:

                  (a) The ownership of an  Unregistered  Security of any series,
         or of any Coupon attached thereto at its issuance,  and the identifying
         number of such Security and the date of such  ownership,  may be proved
         by the  production  of such  Security  or  Coupon  or by a  certificate
         executed by any trust company,  bank,  banker or recognized  securities
         dealer,  wherever situated,  if such certificate shall be deemed by the
         Trustee to be satisfactory.  Each such  certificate  shall be dated and
         shall state that on the date thereof a Security of such series  bearing
         a specified  identifying number was deposited with or exhibited to such
         trust  company,  bank,  banker or recognized  securities  dealer by the
         person named in such certificate. Any such certificate may be issued in
         respect of one or more  Unregistered  Securities  of one or more series
         specified  therein.  The  ownership  by the  Person  named  in any such
         certificate of any  Unregistered  Security  specified  therein shall be
         presumed to continue  unless at the time of any  determination  of such
         ownership  and  holding (1)  another  certificate  bearing a later date
         issued in respect of such Security shall be produced, (2) such security
         shall be produced by some other Person or (3) such Security  shall have
         ceased to be Outstanding.

         Subject to Sections 6.1 and 6.2, the fact and date of the execution of
         any such instrument and the ownership, amount

                                      -65-

<PAGE>



         and  numbers  of any  Unregistered  Securities  may also be  proven  in
         accordance  with  such  reasonable  rules  and  regulations  as  may be
         prescribed  by the Trustee for any series or in any other  manner which
         the Trustee may deem sufficient.

                  (b) In the case of  Registered  Securities,  the  ownership of
         such  Securities  shall be  proved  by the  Security  Register  or by a
         certificate of the Security Registrar.

                  SECTION 7.3 Holders to be Treated as Owners.  The Issuer,  the
Trustee and any agent of the Issuer or the Trustee may deem and treat the Person
in whose name any Security of any series shall be  registered  upon the Security
Register for such series as the absolute owner of such Security  (whether or not
such Security shall be overdue and  notwithstanding any notation of ownership or
other writing thereon) for the purpose of receiving  payment of or on account of
the principal of and, subject to the provisions of this Indenture,  interest on
such Security and for all other  purposes;  and none of the Issuer,  the Trustee
and any agent of the Issuer or the  Trustee  shall be  affected by any notice to
the contrary. The Issuer, the Trustee and any agent of the Issuer or the Trustee
may treat the Holder of any  Unregistered  Security and the Holder of any Coupon
as the absolute owner of such  Unregistered  Security or Coupon  (whether or not
such  Unregistered  Security  or Coupon  shall be  overdue)  for the  purpose of
receiving payment thereof or on account thereof and for all other purposes;  and
none of the Issuer, the Trustee and any agent of the Issuer or the Trustee shall
be affected by any notice to the contrary. All such payments so made to any such
Person, or upon his order, shall be valid, and, to the extent of the sum or sums
so paid,  effectual to satisfy and discharge  the  liability for moneys  payable
upon any such Security or Coupon.

                  SECTION 7.4 Securities Owned by Issuer Deemed Not Outstanding.
In determining  whether the Holders of the requisite  aggregate principal amount
of Outstanding Securities of one or more series have concurred in any direction,
consent or waiver under this Indenture, Securities which are owned by the Issuer
or any other obligor on the Securities with respect to which such  determination
is being made or by any Person directly or indirectly  controlling or controlled
by or under  direct or  indirect  common  control  with the  Issuer or any other
obligor on the Securities with respect to which such determination is being made
shall be disregarded  and deemed not to be  Outstanding  for the purposes of any
such  determination,  except  that for the  purpose of  determining  whether the
Trustee shall be protected in relying on any such direction,  consent or waiver,
only  Securities  which the Trustee knows are so owned shall be so  disregarded.
Securities so owned which have been pledged in good faith may be

                                      -66-

<PAGE>



regarded as Outstanding if the pledgee  establishes to the  satisfaction  of the
Trustee the pledgee's  right so to act with respect to such  Securities and that
the pledgee is not the Issuer or any other  obligor upon such  Securities or any
Person  directly or indirectly  controlling  or controlled by or under direct or
indirect common control with the Issuer or any other obligor on such Securities.
In case of a dispute  as to such  right,  the  advice of  counsel  shall be full
protection  in respect of any decision  made by the Trustee in  accordance  with
such  advice.  Upon  request of the  Trustee,  the Issuer  shall  furnish to the
Trustee   promptly  an  Officers'   Certificate   listing  and  identifying  all
Securities,  if any,  known  by the  Issuer  to be  owned  or held by or for the
account of any of the above described Persons;  and, subject to Sections 6.1 and
6.2,  the Trustee  shall be entitled to accept  such  Officers'  Certificate  as
conclusive  evidence  of the  facts  therein  set forth and of the fact that all
securities  not listed  therein  are  Outstanding  for the  purposes of any such
determination.

                  SECTION 7.5  Right of Revocation of Action Taken.  At
any time prior to (but not after) the evidencing to the Trustee, as provided in 
Section 7.1, of the taking of any action by the Holders of the requisite 
percentage in aggregate principal amount of the Securities of one or more 
series, as the case may be, specified in this Indenture in connection with such
action, any Holder of a Security the serial number of which is shown by the
evidence to be included among the serial numbers of the Securities the Holders 
of which have consented to such action may, by filing written notice at the 
Corporate Trust Office and upon proof of ownership as provided in Section 7.2, 
revoke such action so far as concerns such Security.  Except as aforesaid,
any such action taken by the Holder of any Security of any series shall be 
conclusive and binding upon such Holder and upon all future Holders and owners 
of such Security and of any Securities of such series issued in exchange or 
substitution therefor or on registration of transfer thereof, irrespective of 
whether or not any notation in regard thereto is made upon any such Security. 
Any action taken by the Holders of the requisite percentage in aggregate 
principal amount of the Securities of one or more series, as the case may be, 
specified in this Indenture in connection with such action shall be conclusively
binding upon the Issuer, the Trustee and the Holders of all the Securities of
such series.

                  With  respect to  Registered  Securities,  the Issuer may, but
shall not be obligated to, fix a record date for the purpose of determining  the
Securityholders  entitled  to give  their  consent  or  take  any  other  action
described above. If a record date is fixed, then notwithstanding the immediately
preceding paragraph those Persons who were Holders of such Registered Securities
at such record date (or their duly designated proxies), and only

                                      -67-

<PAGE>



those  Persons,  shall be entitled to give such consent or to revoke any consent
previously  given or to take any such  action  with  respect to such  Registered
Securities, whether or not such Persons continue to be Holders after such record
date.  No such consent  shall be valid or effective for more than 120 days after
such record date.

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

                  SECTION  8.1  Supplemental   Indentures   Without  Consent  of
Securityholders.  The Issuer,  when  authorized  by a resolution of the Board of
Directors  (which  resolution  may provide  general terms or parameters for such
action and may provide that the specific  terms of such action may be determined
in accordance  with or pursuant to an Issuer  Order),  and the Trustee may, from
time  to  time  and  at any  time,  enter  into  an  indenture  or  indentures
supplemental  hereto  (which  shall  conform  to the  provisions  of  the  Trust
Indenture Act of 1939 as in force at the date of the execution  thereof) for one
or more of the following purposes:

                  (a)      subject to Section 3.6, to convey, transfer,
         assign, mortgage or pledge to the Trustee as security for
         the Securities of one or more series any property or assets;

                  (b)      to add guarantees with respect to the Securities
         of one or more series;

                  (c) to evidence the  succession of another  corporation to the
         Issuer, or successive successions,  and the assumption by the successor
         corporation of the covenants,  agreements and obligations of the Issuer
         pursuant to Article Nine;

                  (d) to  add  to the  covenants  of  the  Issuer  such  further
         covenants, restrictions, conditions or provisions as the Issuer and the
         Trustee  shall  consider  to be for the  protection  of the  Holders of
         Securities of any series or Coupons  appertaining  thereto, and to make
         the  occurrence,  or the  occurrence and  continuance,  of a default in
         complying with any such additional covenant, restriction,  condition or
         provision an Event of Default  permitting the enforcement of all or any
         of the several remedies provided in this Indenture as herein set forth;
         in respect of any such additional covenant,  restriction,  condition or
         provision,  such  supplemental  indenture  may provide for a particular
         period of grace after  default  (which  period may be shorter or longer
         than that allowed in the case of other  defaults) or may provide for an
         immediate  enforcement  upon such an Event of  Default or may limit the
         remedies available to the

                                      -68-

<PAGE>



         Trustee  upon  such an Event of  Default  or may limit the right of the
         Holders of a majority in aggregate  principal  amount of the Securities
         of such series to waive such an Event of Default;

                  (e) to cure any  ambiguity  or to  correct or  supplement  any
         provision  contained herein or in any supplemental  indenture which may
         be defective or inconsistent with any other provision  contained herein
         or in any supplemental  indenture,  or to make such other provisions as
         the Issuer  may deem  necessary  or  desirable,  provided  that no such
         action  shall  adversely  affect the  interests  of the  Holders of the
         Securities of any series or the Coupons appertaining thereto;

                  (f)      to establish the form and terms of the securities
         of any series or of the Coupons appertaining to such
         Securities, as permitted by Sections 2.1 and 2.3;

                  (g) to evidence and provide for the  acceptance of appointment
         hereunder by a successor  trustee with respect to the Securities of one
         or more  series and to add to or change any of the  provisions  of this
         Indenture  as shall be  necessary  to  provide  for or  facilitate  the
         administration of the trusts hereunder by more than one trustee, all as
         provided in Section 6.11;

                  (h) to provide for uncertificated Securities in addition to or
         in  place  of  certificated  Securities;  provided,  however,  that the
         uncertificated Securities are issued in registered form for purposes of
         Section 163(f) of the Internal Revenue Code of 1986, as amended,  or in
         a manner  such that the  uncertificated  Securities  are  described  in
         Section  163(f)(2)(B) of the Internal Revenue Code of 1986, as amended;
         and

                  (i)      to comply with any requirements of the Commission
         in connection with qualifying this Indenture under the Trust
         Indenture Act of 1939.

                  The  Trustee is hereby  authorized  to join with the Issuer in
the  execution  of  any  such  supplemental   indenture,  to  make  any  further
appropriate  agreements and stipulations  which may be therein  contained and to
accept the conveyance,  transfer, assignment, mortgage or pledge of any property
or assets  thereunder,  but the Trustee shall not be obligated to enter into any
such  supplemental  indenture which affects the Trustee's own rights,  duties or
immunities under this Indenture or otherwise.

                  Any supplemental indenture authorized by the provisions
of this Section may be executed without the consent of the

                                      -69-

<PAGE>



Holders of any of the Securities at the time Outstanding, notwithstanding any of
the provisions of Section 8.2.

                  SECTION   8.2   Supplemental   Indentures   With   Consent  of
Securityholders.  With the consent  (evidenced as provided in Article  Seven) of
the Holders of not less than a majority  in  aggregate  principal  amount of the
Securities of all series at the time Outstanding  affected by such  supplemental
indenture (voting as one class), the Issuer,  when authorized by a resolution of
the Board of Directors (which resolution may provide general terms or parameters
for such action and may provide  that the  specific  terms of such action may be
determined in accordance  with or pursuant to an Issuer order),  and the Trustee
may,  from time to time and at any time,  enter into an indenture or  indentures
supplemental  hereto  (which  shall  conform  to the  provisions  of the Trust
Indenture  Act of 1939 as in  force at the date of  execution  thereof)  for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the  provisions  of this  Indenture  or of any  supplemental  indenture or of
modifying in any manner the rights of the Holders of the Securities of each such
series or of the Coupons appertaining to such Securities;  provided that no such
supplemental indenture shall (a) extend the time of payment of the principal, or
any installment of the principal, of any Security or reduce the principal amount
thereof,  or reduce the rate,  alter the method of  computation  of the rate, or
extend the time of payment of interest thereon,  or reduce any amount payable on
the redemption  thereof,  or make the principal  thereof or the interest thereon
payable in any coin or currency  other than that  provided in such  Security and
the  Coupons,  if any,  appertaining  thereto  or in  accordance  with the terms
thereof,  or reduce the amount of the  principal of an Original  Issue  Discount
Security  that would be due and payable  upon an  acceleration  of the  maturity
thereof  pursuant to Section 5.1 or the amount  thereof  provable in bankruptcy,
pursuant to Section 5.2, or alter the  provisions of Section 11.11 or 11.12,  or
impair or affect the right to  institute  suit for the payment  thereof when due
or, if such Security  shall so provide,  any right of repayment at the option of
the Holder,  in each case without the consent of the Holder of each  Security so
affected,  or (b) reduce the percentage in principal  amount of the  Outstanding
Securities of the affected series,  the consent of whose Holders is required for
any  such  supplemental  indenture  or for  any  waiver  provided  for  in  this
Indenture, without the consent of the Holders of each Security so affected.

                  A  supplemental  indenture  which  changes or  eliminates  any
covenant or other  provision of this Indenture which has expressly been included
solely for the benefit of one or more series of  Securities,  or which  modifies
the  rights of the  Holders  of  Securities  of such  series  or of the  Coupons
appertaining  to such  Securities  with respect to such  covenant or  provision,
shall

                                      -70-

<PAGE>



be deemed not to affect  the  rights  under  this  Indenture  of the  Holders of
Securities of any other series or of the Coupons pertaining to such Securities.

                  Upon  the  request  of  the  Issuer,  accompanied  by a  Board
Resolution  complying  with the first  paragraph of this Section and evidence of
the  consent  of the  Holders  of the  Securities  as  aforesaid  and such other
documents,  if any, as may be required by Section  7.1,  the Trustee  shall join
with the Issuer in the  execution  of such  supplemental  indenture  unless such
supplemental  indenture  affects the Trustee's own rights,  duties or immunities
under  this  Indenture  or  otherwise,  in  which  case the  Trustee  may in its
discretion,  but  shall  not be  obligated  to,  enter  into  such  supplemental
indenture.

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

                  Promptly  after the execution by the Issuer and the Trustee of
any  supplemental  indenture  pursuant to the  provisions of this  Section,  the
Trustee  shall  give  notice  thereof  (i) to the  Holders  of then  Outstanding
Registered  Securities  of each  series  affected  thereby,  by mailing a notice
thereof by  first-class  mail to such  Holders at their  addresses as they shall
appear on the Security Register, (ii) if any Unregistered Securities of a series
affected  thereby are then  Outstanding,  to the Holders  thereof who have filed
their names and addresses with the Trustee  pursuant to Section  4.4(c)(ii),  by
mailing a notice thereof by  first-class  mail to such Holders at such addresses
as were so furnished to the Trustee and (iii) if any Unregistered  Securities of
a series  affected  thereby are then  Outstanding,  to all Holders  thereof,  by
publication of a notice thereof at least once in each Authorized  Newspaper with
respect to such series,  and in each case such notice shall set forth in general
terms the substance of such supplemental indenture. Any failure of the Issuer to
give such notice, or any defect therein,  shall not, however,  in any way impair
or affect the validity of any such supplemental indenture.

                  SECTION  8.3  Effect  of  Supplemental  Indenture.   Upon  the
execution of any supplemental  indenture pursuant to the provisions hereof, this
Indenture  shall be and be deemed  to be  modified  and  amended  in  accordance
therewith and the respective rights, limitations of rights, obligations,  duties
and immunities  under this Indenture of the Trustee,  the Issuer and the Holders
of Securities of each series  affected  thereby shall  thereafter be determined,
exercised and enforced  hereunder subject in all respects to such  modifications
and  amendments,  and all the  terms  and  conditions  of any such  supplemental
indenture shall be and be

                                      -71-

<PAGE>



deemed to be part of the terms and conditions of this Indenture for any and
all purposes.

                  SECTION 8.4  Documents  to Be Given to Trustee.  The  Trustee,
subject to the  provisions  of Sections  6.1 and 6.2,  may receive an  Officers'
Certificate  and  an  Opinion  of  Counsel  as  conclusive   evidence  that  any
supplemental  indenture  executed  pursuant to this  Article  complies  with the
applicable provisions of this Indenture.

                  SECTION 8.5 Notation on Securities in Respect of  Supplemental
Indentures.  Securities  of any series  authenticated  and  delivered  after the
execution  of any  supplemental  indenture  pursuant to the  provisions  of this
Article  may bear a notation  in form  approved  by the Trustee as to any matter
provided for by such supplemental indenture. If a supplemental indenture changes
the terms of a Security,  the Trustee may require the Holder of such Security to
deliver it to the Trustee,  and the Trustee may place an appropriate notation on
the  Security  regarding  the  changed  terms  and  return  it to  such  Holder.
Alternatively,  if the Issuer or the Trustee shall so determine,  new Securities
of any series so modified  as to conform,  in the opinion of the Trustee and the
Issuer, to any modification of this Indenture contained in any such supplemental
indenture  may be  prepared  by the  Issuer,  authenticated  by the  Trustee and
delivered in exchange for the  Securities of such series then  Outstanding.  Any
failure to make any such notation or to issue a new Security shall not, however,
in any way impair or affect the validity of any such  supplemental  indenture or
any such Security the terms of which are changed.

                  SECTION 9.1 Covenant of Issuer Not to Merge, Consolidate, Sell
or Convey Property Except Under Certain  Conditions.  Nothing  contained in this
Indenture or in any of the  Securities  shall prevent any  consolidation  of the
Issuer with, or merger of the Issuer into, any other Person or Persons  (whether
or not affiliated with the Issuer),  or successive  consolidations or mergers to
which the Issuer or its successor or successors shall be a party or parties,  or
shall prevent any sale,  lease or conveyance of the property of the Issuer as an
entirety or substantially as an entirety;  provided, that, and the Issuer hereby
covenants  and  agrees,  upon any such  consolidation,  merger,  sale,  lease or
conveyance, the due and punctual payment of the principal of and interest on all
the Securities,  according to their tenor, and the due and punctual  performance
and observance of all of the covenants, conditions and other obligations of this

Indenture and the Securities to be performed or observed by the Issuer, shall be
expressly  assumed,  by  supplemental  indenture  satisfactory  in  form  to the
Trustee,  executed  and  delivered  to the Trustee by the Person  formed by such
consolidation,  or into which the Issuer shall have been merged,  or which shall
have acquired such property;  provided,  further, that the Person formed by such
consolidation or into which the Issuer is merged or the Person which acquired by
conveyance or sale, or which leases,  the properties and assets of the Issuer as
an  entirety  or  substantially  as an  entirety  shall be  either  (i) a Person
organized and existing under the laws Of the United States, any state thereof or
the District of Columbia or (ii) a Person  organized and existing under the laws
of Canada,  Japan,  Australia,  New Zealand, any Specified European Nation or of
any political  subdivision  of any thereof and such Person  undertakes to pay to
the Holders of Securities  any  additional  amounts as may be necessary in order
that every net payment of principal of and interest,  if any, on the Securities,
after withholding for or on account of any present or future tax,  assessment or
governmental  charge imposed upon such Holder  (except for a tax,  assessment or
charge imposed solely as a result of a connection  between the recipient and the
jurisdiction imposing such tax assessment or charge) by reason of or as a result
of such payment being made by an entity which is not a Person existing under the
laws of the United States or any state thereof or the District of Columbia, will
not be less than the amount  provided for in the  Securities  to be then due and
payable;  and provided,  further,  that immediately  after giving effect to such
transaction  (and  treating any Secured Debt or Sale and  Leaseback  Transaction
which becomes an obligation of the resulting,  surviving or transferee Person as
a result of such  transaction  as having been  incurred or entered  into by such
Person  at the time of such  transaction),  no Event  of  Default,  and no event
which,  after notice or lapse of time or both, would become an Event of Default,
shall have happened and be continuing.

                  SECTION 9.2  Securities to be Secured in Certain  Events.  If,
upon any such consolidation or merger of the Issuer or upon any such sale, lease
or conveyance of the property of the Issuer as an entirety or  substantially  as
an entirety to any other Person,  any property  owned by the Issuer  immediately
prior thereto  would  thereupon  become  subject to any Lien (unless the Secured
Debt in respect of such Lien could have been incurred by the Issuer  without its
being required by the provisions of Section 3.6 to secure the Securities equally
and ratably with (or prior to) such Secured Debt), the Issuer, prior to any such
consolidation,   merger,   sale,  lease  or  conveyance,   will  by  indenture
supplemental hereto secure the Securities (together with, if the Issuer shall so
determine, any other Debt incurred,  assumed or guaranteed by the Issuer ranking
equally with, or prior to, the  Securities,  whether then existing or thereafter
created) by a

                                      -73-

<PAGE>



direct  Lien on such  property,  prior to all Liens  other than any  theretofore
existing thereon.

                  SECTION 9.3 Successor Person  Substituted for Issuer.  In case
of any consolidation,  merger,  sale, lease or conveyance referred to in Section
9.1, and following  such an assumption by the successor  Person,  such successor
Person shall succeed to and be substituted for the Issuer,  with the same effect
as if it had been named herein.

                  Such  successor  Person may cause to be signed,  and may issue
either in its own name or in the name of the  Issuer  prior to such  succession,
any or all of the Securities issuable hereunder which theretofore shall not have
been signed by the Issuer and  delivered to the Trustee;  and, upon the order of
such  successor  Person,  instead of the  Issuer,  and subject to all the terms,
conditions  and  limitations  in this  Indenture  prescribed,  the Trustee shall
authenticate  and shall deliver any Securities  which previously shall have been
signed  and  delivered  by  the  officers  of the  Issuer  to  the  Trustee  for
authentication,  and any Securities which such successor Person thereafter shall
cause to be signed and  delivered  to the Trustee for that  purpose.  All of the
Securities  so issued shall in all respects have the same legal rank and benefit
under this  Indenture as the  Securities  theretofore  or  thereafter  issued in
accordance with the terms of this Indenture as though all of such Securities had
been issued at the date of the execution hereof.

                  In case of any  such  consolidation,  merger,  sale,  lease or
conveyance  such changes in  phraseology  and form (but not in substance) may be
made in the Securities thereafter to be issued as may be appropriate.

                  In the  event of any such  sale or  conveyance  (other  than a
conveyance  by way of lease),  the Issuer or any  successor  Person  which shall
theretofore  have become such in the manner  described in this Article  shall be
discharged  from all  obligations  and  covenants  under this  Indenture and the
Securities and may be liquidated and dissolved.

                  SECTION  9.4  Officers'  Certificate  and  Opinion  of Counsel
Delivered to Trustee. The Trustee, subject to the provisions of Sections 6.1 and
6.2, may receive an Officers' Certificate and an Opinion of Counsel each stating
that any such consolidation,  merger,  sale, lease or conveyance,  that any such
assumption,  that any such supplemental  indenture and that any such liquidation
or dissolution, complies with the applicable provisions of this Indenture.

at any time (a) the Issuer shall have paid or caused to be paid the principal of

including all Coupons  appertaining  thereto (other than  Securities and Coupons
appertaining  thereto which have been  destroyed,  lost or stolen and which have
been replaced or paid as provided in Section 2.9), in accordance  with the terms
of this Indenture and such Securities or (b) as to Securities and Coupons not so
paid,  the Issuer  shall have  delivered  to the  Trustee for  cancellation  all
Securities of each series theretofore authenticated and all Coupons appertaining

thereto at  maturity;  and if, in the case of (a),  (b) or (c), the Issuer shall
also pay or cause to be paid all other sums  payable  hereunder  by the  Issuer,
then this  Indenture  shall,  subject  to Section  10.6,  cease to be of further

Issuer accompanied by 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, and at the
cost and expense of the Issuer,  shall execute proper instruments  acknowledging

the  Trustee,  at the cost and expense of the  Issuer,  shall,  at the  Issuer's
request, execute proper instruments acknowledging the same, if:

                  (a) the Issuer shall have  irrevocably  deposited or caused to
         be irrevocably  deposited with the Trustee as a trust fund specifically
         pledged as security  for, and  dedicated  solely to, the benefit of the
         Holders  of the  Securities  of such  series and  Coupons  appertaining
         thereto (i) cash in an amount, or (ii) Government Obligations, maturing
         as to principal  and interest at such times and in such amounts as will
         insure  the  availability  of  cash,  or (iii) a  combination  thereof,
         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 (A) the principal and interest
         on all  Securities of such series and Coupons  appertaining  thereto on
         each date that such  principal  or  interest is due and payable and (B)
         any mandatory sinking fund or analogous  payments on the dates on which
         such payments are due and payable in accordance  with the terms of this
         Indenture and the Securities of such series;

                  (b) no Event of Default or event  which,  with notice or lapse
         of time or both,  would  become an Event of Default with respect to the
         Securities  of such series shall have occurred and be continuing on the
         date of such deposit or,  insofar as clauses (e) and (f) of Section 5.1
         are  concerned,  at any time  during the period  ending on the 91st day
         after the date of such deposit (it being understood that this condition
         shall not be deemed satisfied until the expiration of such period);

                  (c) such deposit, defeasance and discharge shall not result in
         a breach or violation of, or constitute a default under, this Indenture
         or any other  agreement or instrument to which the Issuer is a party or
         by which it is bound;

                  (d) such deposit, defeasance and discharge shall not cause any
         Securities  of such  series  then  listed  on any  national  securities
         exchange registered under the Exchange Act to be delisted;

                  (e) the Issuer shall have  delivered to the Trustee an Opinion
         of Counsel (which counsel shall be counsel  selected by the Issuer with
         national  recognition  in  matters  of  federal  income tax law) to the
         effect  that  either  (A)  there  has been a change  in the  applicable
         Federal  income tax law or (B) the Issuer has received  from,  or there
         has been  published  by, the Internal  Revenue  Service a ruling to the
         effect that, and in any such case referred to in clause (A)

                                      -77-

<PAGE>



         or (B) such Opinion of Counsel  shall confirm that based  thereon,  the
         Holders of the Securities of such series then  Outstanding  and Coupons
         appertaining  thereto  will  not  recognize  income,  gain or loss  for
         Federal income tax purposes as a result of such deposit, defeasance and
         discharge  and  will be  subject  to  Federal  income  tax on the  same
         amounts,  in the same  manner  and at the same times as would have been
         the case if such  deposit,  defeasance  and discharge had not occurred;
         and

                  (f)  the  Issuer  shall  have  delivered  to  the  Trustee  an
         Officers'  Certificate and an Opinion of Counsel, each stating that all
         conditions  precedent  herein  provided for relating to the  defeasance
         contemplated by this paragraph have been complied with.

                  (C) The Issuer shall be released  from its  obligations  under
Sections  3.5,  3.6 and 3.7 and  Article  Nine  (other than the first and second
provisos of Section 9.1 with respect to the  Securities  of a particular  series
and any  Coupons  appertaining  thereto  Outstanding)  on and after the date the
conditions set forth below are satisfied  (hereinafter,  "covenant defeasance").
Covenant  defeasance  means that, with respect to the Outstanding  Securities of
such  series,  the Issuer may omit to comply with and shall have no liability in
respect of any term,  condition or limitation set forth in Sections 3.5, 3.6 and
3.7 and Article Nine,  whether directly or indirectly by reason of any reference
elsewhere  herein to any such Section or Article,  by reason of any reference in
such  Section  or  Article  to any  other  provision  herein or by reason of any
reference  to any such  Section  or  Article  in any  other  document,  and such
omission to comply shall not  constitute  an Event of Default  under Section 5.1
with respect to the Outstanding  Securities of such series, but the remainder of
this Indenture and other Outstanding  Securities and Coupons shall be unaffected
thereby.  The following shall be the conditions to application of this paragraph
(C):

                  (a) the Issuer shall have  irrevocably  deposited or caused to
         be irrevocably  deposited with the Trustee as a trust fund specifically
         pledged as security  for, and  dedicated  solely to, the benefit of the
         Holders  of the  Securities  of such  series and  Coupons  appertaining
         thereto,  (i)  cash  in an  amount,  or  (ii)  Government  Obligations,
         maturing as to principal and interest at such times and in such amounts
         as will  insure  the  availability  of  cash,  or  (iii) a  combination
         thereof,  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 (A) the principal and interest
         on all  Securities of such series and Coupons  appertaining  thereto on
         each date that such principal or interest is due and

                                      -78-

<PAGE>



         payable and (B) any mandatory sinking fund or analogous payments on the
         dates on which such payments are due and payable in accordance with the
         terms of this Indenture and the Securities of such series;

                  (b) no Event of Default or event  which,  with notice or lapse
         of time or both,  would  become an Event of Default with respect to the
         Securities  of such series shall have occurred and be continuing on the
         date of such deposit or,  insofar as clauses (e) and (f) of Section 5.1
         are concerned, at any time during the period ending on the 91st day
         after the date of such deposit (it being understood that this condition
         shall not be deemed satisfied until the expiration of such period);

                  (c) such deposit and covenant defeasance shall not result in a
         breach or violation of, or constitute a default  under,  this Indenture
         or any other  agreement or instrument to which the Issuer is a party or
         by which it is bound;

                  (d) such deposit and covenant  defeasance  shall not cause any
         Securities  of such  series  then  listed  on any  national  securities
         exchange registered under the Exchange Act to be delisted;

                  (e) the Issuer shall have  delivered to the Trustee an Opinion
         of Counsel (which counsel shall be counsel  selected by the Issuer with
         national  recognition  in  matters  of  federal  income tax law) to the
         effect  that  the  Holders  of  the  Securities  of  such  series  then
         Outstanding and Coupons appertaining thereto will not recognize income,
         gain or loss for  Federal  income  tax  purposes  as a  result  of such
         deposit and covenant  defeasance  and will be subject to Federal income
         tax on the same  amounts,  in the same  manner and at the same times as
         would have been the case if such  deposit and covenant  defeasance  had
         not occurred; and

                  (f)  the  Issuer  shall  have  delivered  to  the  Trustee  an
         Officers'  Certificate and an Opinion of Counsel, each stating that all
         conditions  precedent  herein  provided for  relating to such  covenant
         defeasance have been complied with.

                  SECTION 10.2  Application  by Trustee of Funds  Deposited  for
Payment of Securities.  Subject to Section 10.4,  all moneys  deposited with the
Trustee  pursuant to Section 10.1 in respect of the Outstanding  Securities of a
particular  series and the Coupons  appertaining  thereto shall be held in trust
and applied by it to the  payment,  either  directly or through any paying agent
(including  the Issuer acting as its own paying  agent),  to the Holders of such
Securities and Coupons of all sums due and to

                                      -79-

<PAGE>



become  due  thereon  for  principal  and  interest;  but such money need not be
segregated from other funds except to the extent required by law.

                  SECTION  10.3  Repayment  of Moneys Held by Paying  Agent.  In
connection with the satisfaction and discharge of this Indenture with respect to
the Securities of any series, all moneys then held by any paying agent under the
provisions of this  Indenture  with respect to such series of Securities  shall,
upon demand of the Issuer,  be paid to the  Trustee  and  thereupon  such paying
agent shall be released from all further liability with respect to such moneys.

                  SECTION 10.4 Return of Moneys Held by Trustee and Paying Agent
Unclaimed for Two Years. Any moneys deposited with or paid to the Trustee or any
paying agent for the payment of the  principal of or interest on any Security of
any  series or  Coupons  appertaining  thereto  and not  applied  but  remaining
unclaimed  for two years  after the date upon which such  principal  or interest
shall have become due and payable, shall, upon the written request of the Issuer
and unless otherwise  required by mandatory  provisions of applicable escheat or
abandoned or unclaimed  property  law, be repaid to the Issuer by the Trustee or
such paying  agent,  and the Holder of the  Securities of such series and of any
Coupons  appertaining  thereto  shall,  unless  otherwise  required by mandatory
provisions  of  applicable  escheat or  abandoned or  unclaimed  property  laws,
thereafter  look only to the Issuer  for any  payment  which such  Holder may be
entitled to collect,  and all  liability of the Trustee or any paying agent with
respect to such  moneys  shall  thereupon  cease;  provided,  however,  that the
Trustee or such paying agent,  before being  required to make any such repayment
with  respect  to moneys  deposited  with it for any  payment  (a) in respect of
Registered Securities of any series, shall at the expense of the Issuer, mail by
first-class  mail to Holders of such Securities at their addresses as they shall
appear on the  Security  Register  for the  Securities  of such  series,  (b) in
respect of  Unregistered  Securities of any series,  shall at the expense of the
Issuer,  mail by first-class  mail to Holders of such  Securities who have filed
their names and  addresses  with the Trustee  pursuant to Section  4.4(c)(ii) at
such  addresses  as were so  furnished  to the  Trustee  and (c) in  respect  of
Unregistered  Securities of any series, shall at the expense of the Issuer cause
to be published once, in each Authorized  Newspaper with respect to such series,
notice that such moneys remain and that, after a date specified  therein,  which
shall not be less than 30 days from the date of such mailing or publication, any
unclaimed balance of such moneys then remaining will be repaid to the Issuer.

                  SECTION 10.5  Indemnity for Government Obligations.
The Issuer shall pay and indemnify the Trustee against any tax,

                                      -80-

<PAGE>



fee or other charge imposed on or assessed  against the  Government  Obligations
deposited  pursuant to Section  10.1 or the  principal  or interest  received in
respect of such  Government  Obligations,  other than any such tax, fee or other
charge  which by law is for the  account of the  Holders of the  Securities  and
Coupons for whose benefit such Government Obligations are held.

                  SECTION 10.6. Reinstatement. If the Trustee or paying agent is
unable to apply any  money or  Government  Obligation  in  accordance  with this
Article  10 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 Issuer's  obligations  under this
Indenture  and the  Securities  shall be  revived  and  reinstated  as though no
deposit had occurred  pursuant to this Article 10 until such time as the Trustee
or paying agent is permitted to apply all such money or  Government  Obligations
in accordance with this Article 10; provided,  however,  that, if the Issuer has
made any payment of interest on or  principal of any  Securities  because of the
reinstatement of its obligations, the Issuer shall be entitled, at its election,
(a) to receive from the Trustee or paying agent, as applicable,  that portion of
such money or Government  Obligations equal to the amount of such payment or (b)
to be subrogated to the rights of the Holders of such Securities to receive such
payment from the money or Government  Obligations  held by the Trustee or paying
agent.

                            MISCELLANEOUS PROVISIONS
                            ------------------------

                  SECTION  11.1   Incorporators,   Stockholders,   Officers  and
Directors of Issuer Exempt from Individual Liability.  No recourse under or upon
any obligation,  covenant or agreement  contained in this  Indenture,  or in any
Security or Coupon, or because of any indebtedness  evidenced thereby,  shall be
had against any  incorporator,  as such, or against any past,  present or future
stockholder,  officer or director,  as such, of the Issuer or of any  successor,
either  directly or through the Issuer or any successor,  under any rule of law,
statute or  constitutional  provision or by the enforcement of any assessment or
by any legal or equitable  proceeding or  otherwise,  all such  liability  being
expressly  waived and  released  by the  acceptance  of the  Securities  and the
Coupons  appertaining  thereto  by  the  Holders  thereof  and  as  part  of the
consideration  for the  issue of the  Securities  and the  Coupons  appertaining
thereto.

                  SECTION 11.2  Provisions of Indenture for the Sole Benefit
of Parties and Holders of Securities and Coupons.  Nothing in this Indenture,
in the Securities or Coupons

                                      -81-

<PAGE>



appertaining thereto,  expressed or implied,  shall give or be construed to give
to any person,  firm or  corporation,  other than the  parties  hereto and their
successors  and the Holders of the  Securities or Coupons,  if any, any legal or
equitable  right,  remedy or claim under this Indenture or under any covenant or
provision herein contained, all such covenants and provisions being for the sole
benefit of the  parties  hereto and their  successors  and of the Holders of the
Securities or Coupons, if any.

                  SECTION  11.3  Successors  and  Assigns  of  Issuer  Bound  by
Indenture.  All the  covenants,  stipulations,  promises and  agreements in this
Indenture  contained by or on behalf of the Issuer shall bind its successors and
assigns, whether so expressed or not.

                  SECTION  11.4  Notices  and  Demands  on Issuer,  Trustee  and
Holders of Securities  and Coupons.  Any notice or demand which by any provision
of this  Indenture is required or permitted to be given or served by the Trustee
or by any Holder of Securities of any series or Coupons  appertaining thereto to
or upon the  Issuer  may be given or  served  in  person  or by being  deposited
postage prepaid in the United States mail, first-class mail (except as otherwise
specifically provided herein), addressed (until another address of the Issuer is
filed by the Issuer with the  Trustee) to United  States  Cellular  Corporation,
8410 West Bryn Mawr Avenue, Suite 700, Chicago, Illinois 60631- 3486, Attention:
Chief Financial Officer. Any notice, direction,  request or demand by the Issuer
or any Holder of Securities of any series or Coupons  appertaining thereto to or
upon the Trustee may be given or served in person or by being deposited  postage
prepaid  in the United  States  mail,  first-class  mail  (except  as  otherwise
specifically  provided herein),  addressed (until another address of the Trustee
is filed by the Trustee  with the  Issuer) to One First  National  Plaza,  Suite
0216, Chicago,  Illinois 60670-0126,  Attention:  Corporate Trust Services.  Any
notice  required  or  permitted  to be given or served  by the  Issuer or by the
Trustee to or upon (i) any Holders of Registered Securities of any series or any
Holders of Unregistered Securities who have filed their names and addresses with
the  Trustee  pursuant  to Section  4.4(c)(ii),  may be given or served by being
deposited  in the United  States  mail,  first-class  mail  (except as otherwise
specifically provided herein), addressed at their addresses as they shall appear
on the Security  Register or at the addresses so filed,  respectively,  and (ii)
any Holders of other  Unregistered  Securities,  by publication at least once in
each Authorized Newspaper with respect to such series.

                  In any case where notice to the Holders of Securities is given
by mail,  neither the failure to mail such notice,  nor any defect in any notice
so mailed, to any particular Holder

                                      -82-

<PAGE>



shall affect the sufficiency of such notice with respect to other Holders. Where
this Indenture  provides for notice in any manner,  such notice may be waived in
writing by the person  entitled to receive such notice,  either  before or after
the event,  and such waiver shall be the  equivalent of such notice.  Waivers of
notice by Holders shall be filed with the Trustee,  but such filing shall not be
a condition  precedent to the validity of any action taken in reliance upon such
waiver.

                  In case, by reason of the suspension of or  irregularities  in
regular mail  service,  it shall be  impracticable  to mail notice to the Issuer
when such  notice is  required to be given  pursuant  to any  provision  of this
Indenture,  then any  manner  of  giving  such  notice  as  shall be  reasonably
satisfactory  to the Trustee  shall be deemed to be a sufficient  giving of such
notice.

                  SECTION 11.5 Officers'  Certificates  and Opinions of Counsel;
Statements to be Contained Therein. Upon any application or demand by the Issuer
to the Trustee to take any action under any of the provisions of this Indenture,
the Issuer shall  furnish to the Trustee an Officers'  Certificate  stating that
all conditions precedent provided for in this Indenture relating to the proposed
action have been  complied  with and an Opinion of Counsel  stating  that in the
opinion of such counsel all such  conditions  precedent have been complied with,
except  that in the case of any  such  application  or  demand  as to which  the
furnishing of such documents is  specifically  required by any provision of this
Indenture  relating to such  particular  application  or demand,  no  additional
certificate or opinion need be furnished.

                  Each certificate or opinion provided for in this Indenture and
delivered to the Trustee with respect to compliance with a condition or covenant
provided for in this  Indenture  shall  include (a) a statement  that the person
making such  certificate  or opinion has read such covenant or condition,  (b) a
brief statement as to the nature and scope of the  examination or  investigation
upon which the statements or opinions  contained in such  certificate or opinion
are based, (c) a statement that, in the opinion of such person, he has made such
examination  or  investigation  as is  necessary  to enable  him 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
person, such condition or covenant has been complied with.

                  Any  certificate,  statement  or  opinion of an officer of the
Issuer may be based, insofar as it relates to legal matters,  upon a certificate
or opinion of or representations by counsel,  unless such officer knows that the
certificate or opinion of or

                                      -83-

<PAGE>



representations  with  respect  to  the  matters  upon  which  his  certificate,
statement or opinion may be based as aforesaid are erroneous, or in the exercise
of reasonable  care should know that the same are  erroneous.  Any  certificate,
statement  or opinion of counsel may be based,  insofar as it relates to factual
matters,  information  with respect to which is in the possession of the Issuer,
upon the certificate,  statement or opinion of or  representations by an officer
or officers  of the Issuer,  unless  such  counsel  knows that the  certificate,
statement or opinion or  representations  with respect to the matters upon which
his  certificate,  statement or opinion may be based as aforesaid are erroneous,
or in the exercise of reasonable care should know that the same are erroneous.

                  Any  certificate,  statement  or  opinion of an officer of the
Issuer or of counsel may be based,  insofar as it relates to accounting matters,
upon a certificate or opinion of or  representations by an accountant or firm of
accountants in the employ of the Issuer,  unless such officer or counsel, as the
case may be,  knows that the  certificate  or opinion  or  representations  with
respect to the  accounting  matters  upon which his  certificate,  statement  or
opinion  may  be  based  as  aforesaid  are  erroneous,  or in the  exercise  of
reasonable care should know that the same are erroneous.

                  Any certificate or opinion of any  independent  firm of public
accountants  filed with and  directed to the Trustee  shall  contain a statement
that such firm is independent.

                  SECTION 11.6 Payments Due on Saturdays,  Sundays and Holidays.
If the date of maturity of interest on or  principal  of the  Securities  of any
series or any coupons  appertaining  thereto or the date fixed for redemption or
repayment  of any such  Security  or Coupon  shall not be a Business  Day,  then
payment of interest or principal  need not be made on such date, but may be made
on the next succeeding Business Day with the same force and effect as if made on
the date of  maturity  or the date fixed for  redemption  or  repayment,  and no
interest shall accrue for the period after such date.

                  SECTION 11.7 Conflict of Any Provision of Indenture with Trust
Indenture Act of 1939. If and to the extent that any provision of this Indenture
limits,  qualifies or conflicts with another  provision  which is required to be
included  herein by the Trust  Indenture  Act of 1939 (as it may be amended from
time to time), such required provision shall control.

                  SECTION 11.8 Illinois Law to Govern.  This  Indenture and each
Security and Coupon shall be deemed to be a contract under the laws of the State
of Illinois, and for all purposes shall be construed in accordance with the laws
of such State,

                                      -84-

except as may otherwise be required by mandatory provisions of law.

                  SECTION 11.9  Counterparts.  This Indenture may be executed in
any  number  of  counterparts,  each of  which  shall be an  original;  but such
counterparts shall together constitute but one and the same instrument.

                  SECTION  11.10  Effect of  Headings.  The  Article and Section
headings herein and the Table of Contents are for convenience only and shall not
affect the construction hereof.

                  SECTION  11.11  Securities  in a Foreign  Currency  or in ECU.
Unless otherwise specified in or pursuant to a Board Resolution,  a supplemental
indenture or an  Officers'  Certificate  delivered  pursuant to Section 2.3 with
respect to a  particular  series of  securities,  whenever  for purposes of this
Indenture  any action may be taken by the Holders of a specified  percentage  in
aggregate  principal  amount  of  Securities  of one or more  series at the time
Outstanding  and, at such time,  there are Outstanding  Securities of any series
which are denominated in a Foreign Currency (including ECUs), then the principal
amount of Securities of such series which shall be deemed to be Outstanding  for
the purpose of taking such action  shall be the amount of Dollars  that could be
obtained  for such  amount at the Market  Exchange  Rate.  For  purposes of this
Section, Market Exchange Rate shall mean the noon Dollar buying rate in New York
City for cable  transfers of such  Foreign  Currency as published by the Federal
Reserve Bank of New York;  provided,  however,  that in the case of ECUs, Market
Exchange Rate shall mean the rate of exchange  determined  by the  commission of
the European Communities (or any successor thereto) as published in the Official
Journal  of  the  European   Communities  (such  publication  or  any  successor
publication,  the "Journal").  If such Market Exchange Rate is not available for
any reason with respect to such Foreign Currency or ECUs, the Trustee shall use,
in its sole discretion and without  liability on its part, such quotation of the
Federal  Reserve Bank of New York or, in the case of ECUs,  the rate of exchange
as published in the Journal, as of the most recent available date, or quotations
or, in the case of ECUs,  rates of exchange  from one or more major banks in The
City of New York or in the country of issue of the Foreign Currency in question,
which  for  purposes  of the ECU  shall  be  Brussels,  Belgium,  or such  other
quotations  or, in the case of ECU,  rates of exchange as the Trustee shall deem
appropriate.  The  provisions of this  paragraph  shall also apply in connection
with any other action taken by the Holders of  Securities  pursuant to the terms
of this Indenture, including without limitation Section 5.1.

                  All decisions and determinations of the Trustee regarding 
the Market Exchange Rate or any alternative

                                      -85-

<PAGE>



determination  provided  for in the  preceding  paragraph  shall  be in its sole
discretion  and shall,  in the absence of manifest  error,  be conclusive to the
extent permitted by law for all purposes and irrevocably binding upon the Issuer
and all Holders.

                  SECTION 11.12 Judgment  Currency.  The Issuer  agrees,  to the
fullest extent that it may  effectively do so under  applicable law, that (a) if
for the purpose of  obtaining  judgment in any court it is  necessary to convert
the sum due in respect of the principal of or interest on the  Securities of any
series (the  "Required  Currency")  into a currency in which a judgment  will be
rendered (the "Judgment Currency"),  the rate of exchange used shall be the rate
at which,  in  accordance  with normal  banking  procedures,  the Trustee  could
purchase  in The City of New  York  the  Required  Currency  with  the  Judgment
Currency on the day on which final unappealable judgment is entered, unless such
day is not a New York  Banking  Day, in which case,  to the extent  permitted by
applicable  law,  the rate of  exchange  used  shall be the  rate at  which,  in
accordance  with normal  banking  procedures,  the Trustee could purchase in The
City of New York the Required  Currency  with the  Judgment  Currency on the New
York Banking Day next preceding the day on which final unappealable  judgment is
entered and (b) its obligations  under this Indenture and the Securities of such
series to make payments in the Required  Currency (i) shall not be discharged or
satisfied by any tender,  or any recovery  pursuant to any judgment  (whether or
not entered in  accordance  with clause  (a)),  in any  currency  other than the
Required  Currency,  except to the extent  that such  tender or  recovery  shall
result in the effective  receipt by the payee of the full amount of the Required
Currency  expressed  to be payable in  respect of such  payments,  (ii) shall be
enforceable as an  alternative or additional  cause of action for the purpose of
recovering in the Required  Currency the amount, if any, by which such effective
receipt  shall  fall  short of the  full  amount  of the  Required  Currency  so
expressed  to be payable  and (iii)  shall not be  affected  by  judgment  being
obtained  for any other  sums due under  this  Indenture.  For  purposes  of the
foregoing,  "New York Banking Day" means any day except a Saturday,  Sunday or a
legal holiday in The City of New York or a day on which banking  institutions in
The City of New York are  authorized  or required by law or  executive  order to
close.


                                 ARTICLE TWELVE

                   REDEMPTION OF SECURITIES AND SINKING FUNDS
                   ------------------------------------------

                  SECTION 12.1 Applicability of Article.  The provisions of this
Article shall be applicable to the Securities of any series which are redeemable
before their maturity or to any sinking fund for the retirement of Securities of
a series except

                                      -86-

<PAGE>



as otherwise specified as contemplated by Section 2.3 for Securities of any
series.

                  SECTION 12.2 Notice of Redemption; Partial Redemptions. Notice
of  redemption  to the  Holders  of  Registered  Securities  of any series to be
redeemed  as a whole  or in part  shall  be  given  by  mailing  notice  of such
redemption by first class mail,  postage prepaid,  at least 30 days and not more
than 60 days prior to the date fixed for  redemption,  to such  Holders at their
last addresses as they shall appear upon the registry books for such Securities.
Notice of redemption to the Holders of Unregistered  Securities of any series to
be redeemed as a whole or in part, who have filed their names and addresses with
the Trustee pursuant to Section 4.4(c)(ii),  shall be given by mailing notice of
such redemption by first class mail,  postage prepaid,  at least 30 days and not
more than 60 days prior to the date  fixed for  redemption,  to such  Holders at
such addresses as were so furnished to the Trustee (and, in the case of any such
notice given by the Issuer, the Trustee shall make such information available to
the Issuer  for such  purpose).  Notice of  redemption  to all other  Holders of
Unregistered  Securities  of any series shall be  published  in each  Authorized
Newspaper with respect to such series once in each of three successive  calendar
weeks,  the first  publication to be not less than 30 days nor more than 60 days
prior to the date fixed for redemption. Any notice which is mailed in the manner
herein provided shall be conclusively  presumed to have been duly given, whether
or not the Holder  receives the notice.  Failure to give notice by mail,  or any
defect in the notice to the Holder of any Security of any series  designated for
redemption  as a  whole  or in  part,  shall  not  affect  the  validity  of the
proceedings for the redemption of any other Security of such series.

                  The notice of redemption to each such Holder shall specify the
principal  amount of each  Security  of such  series  held by such  Holder to be
redeemed,  the date fixed for  redemption,  the redemption  price,  the place or
places of payment,  that payment will be made upon presentation and surrender of
such Securities and, in the case of Securities with Coupons attached thereto, of
all Coupons  appertaining  thereto maturing after the date fixed for redemption,
that such  redemption is pursuant to the mandatory or optional  sinking or other
analogous fund, or both, if such be the case, that interest  accrued to the date
fixed for redemption will be paid as specified in such notice, that on and after
said date interest  thereon or on the portions thereof to be redeemed will cease
to accrue (unless the Issuer defaults in making such  redemption  payment or the
paying agent is  prohibited  from making such  payment  pursuant to the terms of
this  Indenture)  and that no  representation  is made as to the  correctness or
accuracy of the CUSIP  number,  if any,  listed in such notice or printed on the
Securities. In case any Security is to be redeemed in part only,

                                      -87-

<PAGE>



the notice of redemption shall state the portion of the principal amount thereof
to be redeemed and shall state that on and after the date fixed for  redemption,
upon surrender of such Security,  a new Security or Securities of such series in
authorized  denominations  for  an  aggregate  principal  amount  equal  to  the
unredeemed portion thereof will be issued.

                  The notice of  redemption  of  Securities  of any series to be
redeemed  at the  option of the  Issuer  shall be given by the Issuer or, at the
Issuer's  request,  by the Trustee in the name and at the expense of the Issuer,
in which case the Issuer will provide the Trustee with the information  required
to be included in such notice by the preceding paragraph.

                  On or before the  redemption  date  specified in the notice of
redemption  given as provided in this Section,  the Issuer will deposit with the
Trustee or with one or more  paying  agents  (or, if the Issuer is acting as its
own paying agent, set aside,  segregate and hold in trust as provided in Section
3.4) an amount of money  sufficient  to  redeem on the  redemption  date all the
Securities  of any series so called for  redemption  (other than  Securities  or
portions of Securities  called for  redemption  which have been delivered by the
Issuer to the Trustee  for  cancellation  as  provided  in Section  12.5) at the
applicable  redemption  price,  together with accrued interest to the date fixed
for redemption. The Issuer will deliver to the Trustee at least 70 days prior to
the date fixed for  redemption  an Officers'  Certificate  stating the aggregate
principal  amount of Securities of each series and, if  applicable,  the Tranche
(as hereinafter  defined) to be redeemed.  In case of a redemption at the option
of the Issuer prior to the expiration of any restriction on such redemption, the
Issuer  shall  deliver  to the  Trustee,  prior to the  giving of any  notice of
redemption to Holders pursuant to this Section, an Officers' Certificate stating
that such restriction has been complied with. If less than all the Securities of
like tenor and terms of any series (a "Tranche") are to be redeemed, the Trustee
shall select the  particular  Securities of such Tranche to be redeemed pro rata
or by lot or by a method that complies with the applicable  legal and securities
exchange  requirements,  if  any,  and  that  the  Trustee  considers  fair  and
appropriate  and in accordance  with the methods  generally  used at the time of
selection by fiduciaries in similar circumstances. Securities may be redeemed in
part in multiples equal to the minimum authorized denomination for Securities of
such series or any multiple thereof. If less than all Securities of unlike tenor
and terms of a series are to be redeemed,  the particular  Tranche of Securities
to be  redeemed  shall be selected by the  Issuer.  The Trustee  shall  promptly
notify the  issuer in writing of the  Securities  of such  series  selected  for
redemption and, in the case of any Securities  selected for partial  redemption,
the principal amount thereof to be redeemed. For all purposes of

                                      -88-

<PAGE>



this Indenture,  unless the context otherwise requires,  all provisions relating
to the  redemption of Securities of any series shall relate,  in the case of any
Security  redeemed  or to be  redeemed  only  in  part,  to the  portion  of the
principal amount of such Security which has been or is to be redeemed.

                  SECTION 12.3 Payment of Securities  Called for Redemption.  If
notice of redemption  has been given as provided in Section 12.2, the Securities
or portions of Securities  specified in such notice shall become due and payable
on the date and at the place stated in such notice at the applicable  redemption
price,  together with interest accrued to the date fixed for redemption,  and on
and after said date  (unless  the Issuer  shall  default in the  payment of such
Securities at the applicable redemption price, together with interest accrued to
said date)  interest on the  Securities  or portions of Securities so called for
redemption shall cease to accrue,  the unmatured Coupons,  if any,  appertaining
thereto  shall be void and,  except as provided in Sections  6.5 and 10.4,  such
Securities  shall  cease  from and after the date  fixed  for  redemption  to be
entitled  to any  benefit or  security  under this  Indenture,  and the  Holders
thereof  shall have no right in respect of such  Securities  except the right to
receive the applicable  redemption price thereof and unpaid interest to the date
fixed for  redemption.  On  presentation  and surrender of such  Securities at a
place of payment  specified in said notice,  together with all Coupons,  if any,
appertaining  thereto  maturing  after  the  date  fixed  for  redemption,  such
Securities or the specified  portions  thereof shall be paid and redeemed by the
Issuer at the  applicable  redemption  price,  together  with  interest  accrued
thereon to the date fixed for  redemption;  provided  that  payment of  interest
becoming due on or prior to the date fixed for redemption  shall be payable,  in
the case of  Securities  with Coupons  attached  thereto,  to the Holders of the
Coupons for such interest upon  surrender  thereof or, in the case of Registered
Securities,  to the Holders of such Registered  Securities registered as such on
the relevant  Record Date,  subject to the terms and  provisions of Sections 2.3
and 2.7.

                  If any  Security  called for  redemption  shall not be so paid
upon surrender thereof for redemption,  the principal shall,  until paid or duly
provided for,  bear  interest from the date fixed for  redemption at the rate of
interest  or  Yield  to  Maturity  (in the case of an  Original  Issue  Discount
Security) borne by such Security.

                  If any Security with Coupons  attached  thereto is surrendered
for redemption and is not accompanied by all appurtenant  Coupons maturing after
the date fixed for  redemption,  the surrender of such missing Coupon or Coupons
may be waived by the Issuer and the  Trustee,  if there be  furnished to each of
them

                                      -89-

<PAGE>



such security or indemnity as they may require to save each of them harmless.

                  Upon  presentation of any Security  redeemed in part only, the
Issuer shall execute and the Trustee shall authenticate and deliver to or on the
order of the Holder  thereof,  at the expense of the Issuer,  a new  Security or
Securities of such series,  of  authorized  denominations,  in principal  amount
equal to the unredeemed portion of the Security so presented.

                  SECTION 12.4 Exclusion of Certain  Securities from Eligibility
for Selection for Redemption.  Securities shall be excluded from eligibility for
selection for redemption if they are identified by registration  and certificate
number in an  Officers'  Certificate  delivered  to the Trustee at least 40 days
prior to the last date on which notice of redemption may be given as being owned
of record and  beneficially  by, and not pledged or hypothecated  by, either (a)
the  Issuer  or  (b)  an  entity  specifically   identified  in  such  Officers'
Certificate  as directly or  indirectly  controlling  or  controlled by or under
direct or indirect common control with the Issuer.

                  SECTION 12.5 Mandatory and Optional Sinking Funds. The minimum
amount of any sinking fund payment  provided for by the terms of the  Securities
of any series is herein referred to as a "mandatory  sinking fund payment",  and
any payment in excess of such  minimum  amount  provided for by the terms of the
Securities  of any series is herein  referred to as an  "optional  sinking  fund
payment".  The date on which a  sinking  fund  payment  is to be made is  herein
referred to as the "sinking fund payment date".

                  In lieu of  making  all or any part of any  mandatory  sinking
fund payment with respect to any series of Securities in cash, the Issuer may at
its option (a) deliver to the  Trustee  Securities  of such  series  theretofore
purchased  or  otherwise  acquired  (except  upon  redemption  pursuant  to  the
mandatory  sinking fund) by the Issuer or receive credit for Securities of such
series (not previously so credited)  theretofore purchased or otherwise acquired
(except  as   aforesaid)  by  the  Issuer  and  delivered  to  the  Trustee  for
cancellation  pursuant to Section 2.10, (b) receive credit for optional  sinking
fund payments (not  previously so credited) made pursuant to this Section or (c)
receive  credit for  Securities  of such series  (not  previously  so  credited)
redeemed by the Issuer through any optional  redemption  provision  contained in
the terms of such series.  Securities so delivered or credited shall be received
or credited by the Trustee at the sinking  fund  redemption  price  specified in
such Securities.


                                      -90-

<PAGE>



                  On or before the 60th day next  preceding  each  sinking  fund
payment date for any series, the Issuer will deliver to the Trustee an Officers'
Certificate (which need not contain the statements required by Section 11.5) (a)
specifying the portion of the mandatory sinking fund payment due on such date to
be  satisfied  by payment of cash and the portion to be  satisfied  by credit of
Securities  of such series and the basis for such credit,  (b) stating that none
of the  Securities  of such series to be so  credited  has  theretofore  been so
credited,  (c) stating  that no defaults in the payment of interest or Events of
Default with respect to such series have occurred (which have not been waived or
cured) and are continuing  and (d) stating  whether or not the Issuer intends to
exercise  its right to make an optional  sinking  fund payment on such date with
respect to such  series  and,  if so,  specifying  the  amount of such  optional
sinking  fund  payment  which the  Issuer  intends  to pay on or before the next
succeeding  sinking fund payment  date.  Any  Securities of such series to be so
credited  and required to be delivered to the Trustee in order for the Issuer to
be entitled to credit  therefor as  aforesaid  which have not  theretofore  been
delivered to the Trustee shall be delivered for cancellation pursuant to Section
2.10 to the Trustee with such  Officers'  Certificate  (or  reasonably  promptly
thereafter if acceptable to the Trustee).  Such Officers'  Certificate  shall be
irrevocable,  and upon its  receipt  by the  Trustee  the  Issuer  shall  become
unconditionally  obligated  to make all the cash  payments  or other  deliveries
therein  referred  to, if any,  on or before the next  succeeding  sinking  fund
payment date.  Failure of the Issuer, on or before any such 60th day, to deliver
such Officers'  Certificate and Securities  (subject to the parenthetical in the
immediately  preceding sentence) specified in this paragraph,  if any, shall not
constitute  a default  but  shall  constitute,  on and as of such 60th day,  the
irrevocable  election of the Issuer that (i) the mandatory  sinking fund payment
for such series due on the next  succeeding  sinking  fund payment date shall be
paid entirely in cash without the option to deliver or credit Securities of such
series in respect thereof and (ii) the Issuer will make no optional sinking fund
payment with respect to such series on such date as provided in this Section.

                  If the sinking fund payment or payments (mandatory or optional
or both) to be made in cash on the next  succeeding  sinking  fund  payment date
plus any unused  balance of any  preceding  sinking fund  payments  made in cash
shall exceed $50,000 (or the equivalent thereof in any Foreign Currency or ECU),
or any lesser sum in Dollars (or the equivalent  thereof in any Foreign Currency
or ECU),  if the Issuer shall so request with respect to the  Securities  of any
particular  series,  such cash shall be applied on the next  succeeding  sinking
fund  payment  date  to the  redemption  of  Securities  of such  series  at the
applicable sinking fund redemption price,  together with accrued interest to the
date fixed for redemption. If such amount shall be $50,000

                                      -91-

<PAGE>



(or the  equivalent  thereof  in any  Foreign  Currency  or ECU) or less and the
Issuer makes no such request, then such amount shall be carried over until a sum
in excess of $50,000 (or the equivalent  thereof in any Foreign currency or ECU)
is available.  The Trustee shall select, in the manner provided in Section 12.2,
for redemption on such sinking fund payment date a sufficient  principal  amount
of Securities of such series to absorb said cash, as nearly as may be, and shall
(if requested in writing by the Issuer)  inform the Issuer of the serial numbers
of the Securities of such series (or portions  thereof) so selected.  Securities
shall be excluded from eligibility for redemption under this Section if they are
identified by registration  and certificate  number in an Officers'  Certificate
delivered to the Trustee at least 40 days prior to the sinking fund payment date
as being owned of record and beneficially by, and not pledged or hypothecated by
either (a) the Issuer or (b) an entity specifically identified in such Officers'
Certificate  as directly or  indirectly  controlling  or  controlled by or under
direct or indirect common control with the Issuer. The Trustee,  in the name and
at the expense of the Issuer (or the Issuer,  if it shall so request the Trustee
in writing),  shall cause notice of redemption of the  Securities of such series
to be given in  substantially  the manner provided in Section 12.2 (and with the
effect provided in Section 12.3) for the redemption of Securities of such series
in part at the option of the Issuer. The amount of any sinking fund payments not
so applied or allocated to the  redemption of Securities of such series shall be
added to the next cash sinking fund payment for such series and,  together  with
such  payment,  shall be  applied  in  accordance  with the  provisions  of this
Section. Any and all sinking fund moneys held on the stated maturity date of the
Securities of a particular series (or earlier, if such maturity is accelerated),
which are not held for the payment or  redemption  of  particular  Securities of
such  series,  shall be  applied,  together  with other  moneys,  if  necessary,
sufficient  for the purpose,  to the payment of the principal of and interest on
the Securities of such series at maturity.

                  Unless otherwise  provided for, on or before each sinking fund
payment  date,  the Issuer  shall pay to the Trustee in cash or shall  otherwise
provide for the payment of all interest accrued to the date fixed for redemption
on Securities to be redeemed on such sinking fund payment date.

                  The  Trustee   shall  not  redeem  or  cause  to  be  redeemed
Securities  of any  series  with  sinking  fund  moneys  or give any  notice  of
redemption  of  Securities  of such series by  operation of the sinking fund for
such series  during the  continuance  of a default in the payment of interest on
the  Securities  of such series or of any Event of Default  with respect to such
series except that, if notice of redemption of any Securities of such

                                      -92-

<PAGE>



series shall  theretofore  have been given, the Trustee shall redeem or cause to
be redeemed  such  Securities,  provided  that the Trustee or one or more paying
agents shall have received from the Issuer a sum sufficient for such redemption.
Except as aforesaid,  any moneys in the sinking fund for such series at the time
when any such default or Event of Default shall occur, and any moneys thereafter
paid into the sinking fund,  shall,  during the  continuance  of such default or
Event of Default,  be deemed to have been collected  under Article Five and held
for the payment of all Securities of such series.  In case such Event of Default
shall have been waived as provided  in Section  5.10 or the default  cured on or
before the 60th day preceding  any sinking fund payment date,  such moneys shall
thereafter be applied on such sinking fund payment date in accordance  with this
Section to the redemption of Securities of such series.

                 The Company will pay interest from the later of     or the most
recent Interest  Payment Date (as defined below) to which interest has been paid
or duly provided for, semi-annually on    and       of each year, beginning

                                   % Notes due


                  This Note is one of a duly authorized issue of debt securities
of the Company (herein called the "Securities"), issuable in one or more series,
unlimited in aggregate  principal amount except as may be otherwise  provided in
respect of the Securities of a particular series,  issued and to be issued under
and pursuant to an Indenture dated as of       (herein called the  "Indenture"),
duly executed and delivered by the Company to The First National Bank of 
Chicago,  as Trustee (the "Trustee"),  and is one of a series limited in 
aggregate  principal amount to $    and designated as     % Notes due  
(herein  called  the  "Notes").  Reference  is  hereby  made to the
Indenture for a description of the rights,  limitations of rights,  obligations,
duties and immunities  thereunder of the Trustee, the Company and the Holders of
Securities (including Holders of the Notes).

                  The Notes are  redeemable,  in whole or in part, at the option
of the  Company at any time on or after      at a  redemption  price equal to
100% of the principal  amount of the Notes to be redeemed,  plus accrued
interest thereon, if any, to the date of redemption.

                  Notice of any  redemption  will be mailed at least 30 days but
not more than 60 days before the redemption  date to each Holder of the Notes to
be redeemed.

                  In case of any partial redemption,  selection of the Notes for
redemption  will be made by the Trustee on a pro rata  basis,  by lot or by such
other  method as the  Trustee in its sole  discretion  shall deem to be fair and
appropriate,  although no Note of $1,000 in principal amount at maturity or less
shall be  redeemed  in part.  If any Note is to be  redeemed  in part only,  the
notice of  redemption  relating  to such Note  shall  state the  portion  of the
principal  amount  thereof to be  redeemed.  A new Note in  principal  amount at
maturity equal to the unredeemed  portion  thereof will be issued in the name of
the Holder thereof upon cancellation of the original Note.

                  The Notes are not subject to any sinking fund.

                  The Notes  are  subject  to  defeasance  at the  option of the

except as provided in the Indenture and subject to certain  limitations  therein
set forth, no Global Security shall be exchangeable or transferrable.

                  If an Event of  Default  (as  defined in the  Indenture)  with
respect to the Notes  shall  occur and be  continuing,  the  principal  plus any
accrued  interest  may be  declared  due and  payable in the manner and with the
effect and subject to the conditions provided in the Indenture.

                  The   Indenture   permits  the   amendment   thereof  and  the
modification  of the rights and obligations of the Company and the rights of the
Holders  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
Securities  then  Outstanding of all series which are affected by such amendment
or  modification,  except that certain  amendments which do not adversely affect
the rights of any Holder of the  Securities  may be made without the approval of
Holders of the Securities. No amendment or modification may, among other things,
extend the time of payment of the principal, or any installment of the principal
of any Security,  reduce the principal amount thereof, reduce the rate or extend
the time of payment of any interest thereon, or reduce the aforesaid majority in
aggregate  principal  amount of  Securities  of any  series,  the consent of the
Holders of which is required for any such amendment or modification, without the
consent of each Security holder affected.

                  Notwithstanding   any   provision  in  the  Indenture  or  any
provision of this Note,  the Holder of this Note shall have the right,  which is
