financed through a $1.2 million escrow deposit, $.3 million in prepaid LMA fees,
the forgiveness of a $.1 million note payable and available cash.

(as  defined  in  the  Merger   Agreement)  of   approximately   $64.0  million,

                    AMENDMENT TO AGREEMENT AND PLAN OF MERGER


     This Amendment (this "Amendment"), dated as of July 3, 1996, is made by and
between American Radio Systems Corporation, a Delaware corporation ("American"),
and Henry  Broadcasting  Company,  a California  corporation (the "Company" and,
together with American, the "parties"), to the Agreement and Plan of Merger (the
"Merger Agreement"),  dated as of March 21, 1996, by and between the Company and
American.

                                    RECITALS

     WHEREAS,  the parties  wish to amend and waive  certain  provisions  of the
Merger Agreement; and

     WHEREAS,  the Board of  Directors  of each of the Company and  American has
heretofore  authorized the respective  officers of the company and American,  to
the extent permitted by law to amend and waive the Merger Agreement;

     NOW,  THEREFORE,  in consideration of the foregoing Recitals and the mutual
representations,  warranties,  covenants and  agreements  set forth herein,  the
parties  hereto,  intending to be legally bound, do hereby covenant and agree as
follows:

     1. Defined  Terms.  Capitalized  terms used in this  Amendment that are not
otherwise defined herein shall have the respective  meanings prescribed therefor
in the Merger Agreement.

     2. Section 1071  Acquisitions by American.  American agrees,  to the extent
permitted by the Code, to acquire  sufficient radio broadcast  stations prior to
December 31, 1996 and allocate not less than $5,300,000 of the purchase price of
such stations to the Company in order to enable it to take  advantage of Section
1071 of the Code.

     3. Transfer by Buckley of Shares to Employees.

     American consents to the Company,  prior to the Closing,  issuing shares of
the Company Common Stock to key employees of the Company as follows:

                                                         Number of Shares of
         Name of Transferee                              Company Common Stock

         Caroline J. Erwin                                      3.75
         Jeffrey D. Salgo                                       3.75
         Alvin L. Smith                                         3.75
         Sean C. Buckley                                        3
         Courtney R. Zitelli                                    0.75


                                       -1-


<PAGE>



Accordingly,  the Company will have 1,015  shares,  the other 1,000 shares being
owned by Charlton H. Buckley ("Buckley").

     The Merger  Agreement  shall be, and it hereby is,  deemed to be amended so
that  in each  instance  in  which a  reference  is  made to the  term  "Company
Stockholder"  it shall be  amended  to read the  "Company  Stockholders",  which
shall,  where the  context so  dictates,  refer to all persons  holding  Company
Common  Stock at the time of Closing as set forth  above.  For all  purposes  of
Sections  7.2(l) and 7.2(m),  Article 9 and  elsewhere  in the Merger  Agreement
where it is evident that the reference to "the Company  Stockholder" refers only
to  Buckley,  however,  then the  Merger  Agreement  shall be, and it hereby is,
deemed amended to read so that it refers to "Charlton H. Buckley."

     4. Portland Condominium Not Part of Assets to be Acquired by American.  The
real property described in subparagraph 6 of Section 4.5(b) of the Final Company
Disclosure Statement described as "American Plaza Towers condominium family unit
lot 2022 and  garage  units  GU-149 and GU-151  located  at  2221/2022  SW First
Avenue, Portland,  Oregon 97201" was and is not the property of the Company, was
and is owned by Buckley as an individual,  and was and is not part of the assets
of the Company being acquired by American as a result of the Merger.

     5.  Closing  Date.  The Closing  Date shall be July 3, 1996 and the Company
hereby  waives  any  requirements  of  notice  from  American  pursuant  to  the
provisions of Section 1.3 of the Merger Agreement.

     6. Effective  Time. The Effective Time shall be the filing of a Certificate
of Merger in  accordance  with the DGCL with the Secretary of State of Delaware;
provided,  however,  that notwithstanding the foregoing,  the parties agree that
for financial  reporting  purposes the Merger shall be deemed to be effective as
of the opening of business on July 1, 1996.  The parties  agree to the filing of
the Certificate of Merger of Henry  Broadcasting  Co. and American Radio Systems
Corporation  (the  "Certificate  of Merger")  with the Office of the  California
Secretary  of State after the Closing  Date,  but within six months  thereafter,
subject to the  understanding  that under the California  Corporations  Code the
effective  date of the Merger  shall be the date such  Certificate  of Merger is
effective under the laws of the State of Delaware.

     7. Amendment of Section 3.1(b) of the Merger Agreement.

     (a) The first sentence of Section 3.1(b) of the Merger  Agreement  shall be
amended by deleting the number "$8,000,000" inserting in lieu thereof the number
"$11,000,000".

     (b) The second sentence of Section 3.1(b) of the Merger  Agreement shall be
amended to delete the words "Common Stock  Consideration"  and inserting in lieu
thereof the words "Cash Consideration".

     (c) The provisions of Section  3.1(b) of the Merger  Agreement with respect
to the definition of the term "Current  Market Price" shall be amended to delete
the phrase "the day  immediately  preceding  such date," and  inserting  in lieu
thereof the words "June 28, 1996,".


                                       -2-


<PAGE>

     8. Amendment of Section 7.1(f) of the Merger  Agreement.  Section 7.1(f) of
the Merger Agreement shall be amended to read in its entirety as follows:

               (f) American or one of its  Subsidiaries  shall have entered into
          agreements, in form and substance reasonably satisfactory to American,
          to acquire (i) the following real property  interests of Affiliates of
          the Company for consideration in addition to the Merger  Consideration
          as follows:  (A) the  building  and real  property  located at 1110 E.
          Olive Street, Fresno,  California, for $1,000,000 and (B) the building
          and real property located at 2040 SW First Avenue,  Portland,  Oregon,
          for $1,000,000 and (ii) an option to acquire  approximately  650 acres
          of land  located on Box  Springs  Mountain in San  Bernardino  County,
          California for $1,000,000, such option to be effective for a period of
          five (5) years  following the Closing Date,  and including  management
          rights which would allow the Company to retain and be responsible  for
          all income and expenses at such property.

     9.  Contribution  of Property to the  Company.  On or prior to the Closing,
Buckley  and any other  Affiliate  of the  Company  having any  right,  title or
interest  thereto  shall  have  transferred  to the  Company,  at no cost to the
Company,  all radio  station  equipment  used by or useful to  KSKS(FM)/KMJ(AM),
Fresno,  California,  in which they have any right, title or interest,  free and
clear of all Liens,  and the  representations  and warranties of the Company set
forth in Section  4.5 of the Merger  Agreement  shall be deemed to apply to such
equipment.

     10. Current Asset Distribution.  The Merger Agreement is amended, including
without limitation Section 4.16, to permit the Company to distribute to Buckley,
all cash and  accounts  receivable  of the  Company,  subject,  however,  to his
payment of all accounts  payable and other current  liabilities,  as of the time
immediately  prior to the Effective  Time, it being  understood,  however,  that
American  shall  act as  agent  for,  and  at the  expense  of,  Buckley  in the
collection of such accounts receivable and remit them to him as collected in the
ordinary course of business;  provided,  however, that American may, in its sole
and absolute discretion, resign at any time from acting in such capacity.

     11. Amendments of Closing Conditions.

          (a) Section 7.2(d) of the Merger  Agreement shall be amended to insert

     deleted in their entirety.

          (c) Section 7.3(b) of the Merger  Agreement shall be amended to delete
     the phrase "and of FCC counsel for American,  in form,  scope and substance
     reasonably satisfactory to the Company and its counsel".

     12. Reaffirmation of Merger Agreement;  Incorporation of Provisions. Except
as expressly amended, waived or modified by this Agreement, the Merger Agreement
is hereby reaffirmed by the parties, and the same shall remain in full force and
effect.  The provisions of Article 10 of the Merger  Agreement are  incorporated
herein by reference with the same force and effect as though set forth herein in
their entirety.

     13. Counterparts.  This Agreement may be executed in several  counterparts,
each of which shall be deemed an original, but all of which shall constitute one
and the same instrument, binding upon all of the parties.

         The Company hereby agrees with the several Purchasers as follows:

         2.   Representations  and  Warranties  of  the  Company.   The  Company
represents and warrants to, and agrees with, the several Purchasers that:

                  (a) A preliminary  offering  circular and an offering circular
         relating to the Offered Securities to be offered by the Purchasers have
         been prepared by the Company.  Such preliminary  offering  circular and
         offering  circular,  as  supplemented as of the date of this Agreement,
         together with the  documents  listed in Schedule B hereto and any other
         document  approved  by the  Company  for  use in  connection  with  the
         contemplated   resale  of  the  Offered   Securities  are   hereinafter
         collectively  referred to as the  "Offering  Document".  On the date of
         this  Agreement,  the  Offering  Document  does not  include any untrue
         statement  of a  material  fact or  omit to  state  any  material  fact
         necessary in order to make the statements  therein, in the light of the
         circumstances under which they were made, not misleading. The preceding
         sentence does not apply to statements in or omissions from the Offering
         Document based upon written information furnished to the Company by any
         Purchaser through CS First Boston  Corporation  ("CSFBC")  specifically
         for use  therein,  it being  understood  and agreed  that the only such
         information  is that  described  as such in  Section  7(b).  Except  as
         disclosed in the Offering Document, on the date of this Agreement,  the
         Company's  Annual  Report  on Form 10-K most  recently  filed  with the
         Securities  and  Exchange   Commission  (the   "Commission")   and  all
         subsequent  reports  (collectively,  the "Exchange Act Reports")  which
         have  been  filed  by the  Company  with  the  Commission  or  sent  to
         stockholders  pursuant  to the  Securities  Exchange  Act of 1934  (the
         "Exchange Act") do not include any untrue  statement of a material fact
         or omit to state any  material  fact  required to be stated  therein or
         necessary  to  make  the  statements  therein,  in  the  light  of  the
         circumstances  under  which  they  were  made,  not  misleading.   Such
         documents,  when they were filed with the Commission,  conformed in all
         material respects to the requirements of the Exchange Act and the rules
         and regulations of the Commission thereunder.

                  (b) The Company has been duly  incorporated and is an existing
         corporation  in good standing  under the laws of the State of Delaware,
         with power and authority  (corporate  and other) to own its  properties
         and conduct its business as described in the Offering Document; and the
         Company is duly  qualified to do business as a foreign  corporation  in
         good  standing in all other  jurisdictions  in which its  ownership  or
         lease  of  property  or the  conduct  of  its  business  requires  such
         qualification.

                  (c) Each subsidiary of the Company has been duly  incorporated
         and is an existing  corporation  in good standing under the laws of the
         jurisdiction of its incorporation,  with power and authority (corporate
         and other) to own its  properties and conduct its business as described
         in the Offering  Document;  and each  subsidiary of the Company is duly
         qualified to do business as a foreign  corporation  in good standing in
         all other  jurisdictions in which its ownership or lease of property or
         the conduct of its business  requires  such  qualification;  all of the
         issued and outstanding  capital stock of each subsidiary of the Company
         has been duly  authorized  and  validly  issued  and is fully  paid and
         nonassessable;  and,  except  for the  pledge  pursuant  to the  Credit
         Agreement,  the capital stock of each subsidiary  owned by the Company,
         directly   or  through   subsidiaries,   is  owned  free  from   liens,
         encumbrances and defects.

                  (d) The  Offered  Preferred  Stock and all  other  outstanding
         shares of capital stock of the Company have been duly  authorized;  all
         outstanding  shares of Class A Common Stock and other  capital stock of

         binding  obligation of the Company  enforceable in accordance  with its
         terms,   subject  to  bankruptcy,   insolvency,   fraudulent  transfer,
         reorganization,  moratorium  and similar laws of general  applicability
         relating  to or  affecting  creditors'  rights  and to  general  equity
         principles;  upon  issuance by the  Depositary  on each Closing Date of

                  (f) The Indenture has been duly authorized by the Company; the

         laws of  general  applicability  relating  to or  affecting  creditors'

                  (p) Except as disclosed in the Offering Document,  neither the
         Company nor any of its subsidiaries is in violation of any statute, any

         claim   relating   to  any   environmental   laws,   which   violation,
         contamination,   liability  or  claim  would  individually  or  in  the

         subsidiaries  taken as a whole;  and the  Company  is not  aware of any
         pending investigation which might lead to such a claim.

                  (q) Except as disclosed in the Offering Document, there are no
         pending actions, suits or proceedings against or affecting the Company,
         any of its subsidiaries or any of their respective proper ties that, if

         condition  (financial  or other),  business,  properties  or results of
         operations  of the Company and its  subsidiaries  taken as a whole,  or
         would  materially  and  adversely  affect the ability of the Company to

         operations  and cash flows for the periods  shown,  and such  financial
         statements have been prepared in conformity with the generally accepted

         basis;  and the  assumptions  used in preparing the estimated pro forma

         financial statement amounts.

                  (s) Except as disclosed in the  Offering  Document,  since the
         date  of  the  latest  audited  financial  statements  included  in the
         Offering  Document there has been no material  adverse change,  nor any
         development or event involving a prospective  material  adverse change,
         in the condition (financial or other), business,  properties or results
         of  operations  of the Company and its  subsidiaries  taken as a whole,
         and, except as disclosed in or  contemplated by the Offering  Document,
         there has been no dividend or distribution  of any kind declared,  paid
         or made by the Company on any class of its capital stock.

                  (t) The Company is not an open-end  investment  company,  unit
         investment  trust or face-  amount  certificate  company  that is or is
         required  to  be  registered  under  Section  8 of  the  United  States
         Investment  Company Act of 1940 (the "Investment  Company Act"), nor is

         national securities exchange registered under Section 6 of the Exchange
         Act or quoted in a U.S. automated inter-dealer quotation system.

         meaning of Rule 502(c) under the  Securities Act or (B) with respect to
         any  such  securities  sold in  reliance  on Rule 903 of  Regulation  S
         ("Regulation  S") under the  Securities  Act, by means of any  directed

accumulated  dividends,  if any, from June 25, 1996, the  respective  numbers of
Firm  Securities  set forth  opposite  the names of the  several  Purchasers  in
Schedule A hereto.

         The Company will deliver against payment of the purchase price the Firm

made by the  Purchasers in Federal (same day) funds by official  check or checks
or wire transfer to an account previously  designated to CSFBC by the Company at
a bank  acceptable  to CSFBC  drawn to the order of the Company at the office of

notice and the  Purchasers  agree,  severally and not jointly,  to purchase such
Optional  Securities.  Such  Optional  Securities  shall be  purchased  from the
Company for the account of each  Purchaser in the same  proportion as the number
of Firm Securities set forth opposite such Purchaser's name in Schedule A hereto
bears to the total number of Firm Securities  (subject to adjustment by CSFBC to
eliminate fractions) and may be purchased by the Purchasers only for the purpose
of  covering  over-allotments  made in  connection  with  the  sale of the  Firm
Securities.  No Optional  Securities  shall be sold or delivered unless the Firm
Securities previously have been, or simultaneously are, sold and delivered.  The
right  to  purchase  the  Optional  Securities  or any  portion  thereof  may be

on behalf of the  several  Purchasers  but shall not be later  than  seven  full

is given.  The Company will deliver  against  payment of the purchase  price the
Optional Securities being purchased on each Optional Closing Date in the form of
one or more permanent  global  Securities in definitive form (each, an "Optional
Global  Security")  deposited  with  the  Depositary  as  custodian  for DTC and
registered  in the name of Cede & Co.,  as  nominee  for DTC.  Payment  for such
Optional  Securities shall be made by the Purchasers in Federal (same day) funds
by official check or checks or wire transfer to an account previously designated
to CSFBC by the Company at a bank  acceptable to CSFBC drawn to the order of the
Company at the above  office of  Sullivan &  Cromwell,  against  delivery to the
Depositary as custodian for DTC of the Optional Global  Securities  representing
all of the Optional Securities being purchased on such Optional Closing Date.

         Notwithstanding the foregoing,  any Offered Securities sold in reliance
on Regulation S or sold to  Institutional  Accredited  Investors (as hereinafter
defined)  pursuant  to  Section  4(c)  shall  be  issued  in  definitive,  fully
registered  form and shall  bear the legend  relating  thereto  set forth  under

same  manner  as any  Offered  Securities  to be  purchased  by  the  Purchasers
hereunder  and to be offered and sold by them in reliance on Rule 144A under the
Securities Act.

         Institutional  Accredited  Investor in accordance  with subsection (c),
         such Purchaser will have sent to each distributor, dealer or person

         affiliates  has not  entered  and will not enter  into any  contractual
         arrangement   with  respect  to  the  distribution  of  the  Restricted
         Securities  except for any such  arrangements with the other Purchasers
         or  affiliates  of the  other  Purchasers,  or with the  prior  written
         consent of the Company.

         5.  Certain  Agreements  of the  Company.  The Company  agrees with the
several Purchasers that:

                  (a) The Company will advise CSFBC  promptly of any proposal to
         amend or  supplement  the  Offering  Document  and will not effect such
         amendment or supplementation  without CSFBC's consent.  If, at any time
         prior to the completion of the resale of the Offered  Securities by the
         Purchasers, any event occurs as a result of which the Offering Document
         as then amended or supplemented  would include an untrue statement of a
         material fact or omit to state any material fact  necessary in order to
         make the statements  therein,  in the light of the circumstances  under
         which they were made, not misleading,  the Company promptly will notify
         CSFBC of such event and promptly will prepare,  at its own expense,  an
         amendment or supplement  which will correct such statement or omission.
         Neither CSFBC's consent to, nor the Purchasers' delivery to offerees or
         investors  of, any such  amendment  or  supplement  shall  constitute a
         waiver of any of the conditions set forth in Section 6.

                  (b)  The  Company   will   furnish  to  CSFBC  copies  of  any
         preliminary offering circular, the Offering Document and all amendments
         and  supplements to such  documents,  in each case as soon as available
         and in such quantities as CSFBC requests,  and the Company will furnish
         to CSFBC on the date hereof five copies of the Offering Document signed
         by a duly authorized officer of the Company,  one of which will include
         the independent  accountants'  reports therein  manually signed by such
         independent accountants. At any time when the Company is not subject to
         Section 13 or 15(d) of the  Exchange  Act,  the Company  will  promptly
         furnish or cause to be furnished to CSFBC (and,  upon request,  to each
         of the other  Purchasers)  and, upon request of holders and prospective
         purchasers of the Offered Securities,  the Offered Preferred Stock, the
         Exchange  Debentures  and the  Underlying  Shares,  to such holders and
         purchasers,  copies of the  information  required  to be  delivered  to
         holders and prospective  purchasers of such securities pursuant to Rule
         144A(d)(4)  under  the  Securities  Act  (or  any  successor  provision
         thereto)  in order to permit  compliance  with Rule 144A in  connection
         with resales by such holders of such  securities.  The Company will pay
         the expenses of printing and  distributing  to the Purchasers (and such
         holders and prospective purchasers) all such documents.

                  (c) The  Company  will  arrange for the  qualification  of the
         Offered  Securities for sale and the determination of their eligibility
         for  investment  under  the laws of such  jurisdictions  in the  United
         States  and  Canada  as  CSFBC   designates   and  will  continue  such
         qualifications  in effect  so long as  required  for the  resale of the
         Offered  Securities by the  Purchasers,  provided that the Company will
         not be  required  to  qualify  as a  foreign  corporation  or to file a
         general  consent  to  service  of  process in any such state or subject
         itself to taxation generally in any jurisdiction.

                  (d) During the period of five  years  hereafter,  the  Company
         will  furnish  to  CSFBC  and,  upon  request,  to  each  of the  other
         Purchasers, as soon as practicable after the end of each fiscal year, a
         copy of its  annual  report  to  stockholders  for such  year;  and the
         Company will furnish to CSFBC and, upon  request,  to each of the other
         Purchasers  (i) as soon as  available,  a copy of each  report  and any
         definitive  proxy  statement of the Company  filed with the  Commission
         under the Exchange Act or mailed to stockholders; and (ii) from time to
         time,  such  other  information  concerning  the  Company  as CSFBC may
         reasonably request.

                  (e) During the  period of three  years  after the later of the
         First  Closing Date and the last  Optional  Closing  Date,  the Company
         will, upon request,  furnish to CSFBC, each of the other Purchasers and
         any  holder of  Restricted  Securities  a copy of the  restrictions  on
         transfer applicable to the Restricted Securities.

         under the Securities  Act) to, resell any of the Restricted  Securities
         that have been reacquired by any of them.

                  (g) During the  period of three  years  after the later of the
         First Closing Date and the last Optional Closing Date, the Company will
         not be or become, an open-end investment company, unit investment trust
         or  face-amount  certificate  company  that  is  or is  required  to be
         registered  under Section 8 of the Investment  Company Act, and is not,
         and will not be or become, a closed-end  investment company required to
         be registered, but not registered, under the Investment Company Act.

                  (h) The  Company  will  pay  all  expenses  incidental  to the
         performance of its obligations under this Agreement,  the Indenture and
         the  Deposit  Agreement,  including  (i) the fees and  expenses  of the
         Trustee,  the registrar,  transfer and conversion  agent of the Offered
         Preferred Stock, the Depositary and their professional  advisers;  (ii)
         all expenses in connection with the execution,  issue,  authentication,
         packaging  and  initial  delivery  of  the  Offered   Securities,   the

         thereto,  and any other document relating to the issuance,  offer, sale
         and delivery of the Offered  Securities,  the Offered  Preferred Stock,
         the Underlying  Shares and the Exchange  Debentures;  (iii) the cost of
         qualifying the Offered  Securities for trading in the PORTAL market and
         any expenses incidental  thereto;  and (iv) the cost of any advertising

         disbursements of counsel) incurred in connection with  qualification of
         the Offered Securities for sale under the laws of such jurisdictions in
         the United  States and Canada as CSFBC  designates  and the printing of
         memoranda  relating thereto,  for any fees charged by investment rating

         prospective  purchasers  of the  Offered  Securities  and for  expenses
         incurred  in  distributing   preliminary  offering  circulars  and  the

                  (i) In connection  with the  offering,  until CSFBC shall have

         resale of the  Offered  Securities,  neither the Company nor any of its
         affiliates has or will, either alone or with one or more other persons,
         bid  for  or  purchase  for  any  account  in  which  it or  any of its
         affiliates has a beneficial interest any, Offered  Securities,  Offered
         Preferred  Stock,  Underlying  Shares  or  Exchange  Debentures  or any
         securities  of the same  class as any of the  foregoing  (collectively,
         "Subject  Securities")  or attempt to induce any person to purchase any
         Subject Securities;  and neither it nor any of its affiliates will make
         bids or  purchases  for the purpose of creating  actual,  or  apparent,
         active trading in, or of raising the price of, any Subject Securities.

                  (j) The  Company  will  comply  with the terms of the  Deposit

         the prior written  consent of CSFBC,  except for any such offer,  sale,
         contract  to  sell,  pledge  or  other  disposition  of (i)  any of the
         Restricted  Securities,   (ii)  securities  issued  or  delivered  upon

         sell,  pledge or  otherwise  dispose of,  directly or  indirectly,  any
         securities under circumstances where such offer, sale, pledge, contract
         or  disposition  would cause the exemption  afforded by Section 4(2) of
         the  Securities  Act or the safe harbor of  Regulation S thereunder  to
         cease  to be  applicable  to the  offer  and  sale  of  the  Restricted
         Securities.

         6. Conditions of the Obligations of the Purchasers.  The obligations of
the several Purchasers to purchase and pay for the Restricted Firm Securities on
the First Closing Date and for the Optional  Securities on each Optional Closing
Date will be subject to the accuracy of the  representations  and  warranties on
the part of the Company herein, to the accuracy of the statements of officers of
the Company and the Depositary  made pursuant to the provisions  hereof,  to the
performance  by the Company of its  obligations  hereunder  and to the following
additional conditions precedent:

                  (a) The  Purchasers  shall have  received a letter,  dated the
         date of this  Agreement,  of Deloitte & Touche LLP confirming that they
         are  independent  public  accountants  under  rule 101 of the  American
         Institute of Certified Public Accountants Code of Professional Conduct,
         and its interpretation and rulings.

                  (b)   Subsequent   to  the  execution  and  delivery  of  this
         Agreement,  there  shall  not  have  occurred  (i) any  change,  or any
         development or event involving a prospective  change,  in the condition
         (financial or other), business,  properties or results of operations of
         the Company or its subsidiaries which, in the judgment of a majority in
         interest of the Purchasers including CSFBC, is material and adverse and
         makes it impractical  or inadvisable to proceed with  completion of the
         offering or the sale of and payment  for the Offered  Securities;  (ii)
         any  downgrading in the rating of any debt securities of the Company by
         any "nationally recognized statistical rating organization" (as defined
         for purposes of Rule 436(g) under the  Securities  Act),  or any public
         announcement  that any such  organization  has  under  surveillance  or
         review its rating of any debt  securities of the Company (other than an
         announcement with positive implications of a possible upgrading, and no
         implication  of a  possible  downgrading,  of such  rating);  (iii) any
         suspension or limitation of trading in securities  generally on the New
         York Stock  Exchange,  or any setting of minimum  prices for trading on
         such exchange or on the Nasdaq  National  Market,  or any suspension of
         trading of any  securities  of the  Company on any  exchange  or in the
         over-the-counter  market;  (iv) any banking moratorium declared by U.S.
         Federal or New York  authorities;  or (v) any outbreak or escalation of
         major  hostilities  in  which  the  United  States  is  involved,   any
         declaration  of war by  Congress or any other  substantial  national or
         international  calamity or emergency  if, in the judgment of a majority
         in interest of the Purchasers  including  CSFBC, the effect of any such
         outbreak,  escalation,  declaration,  calamity  or  emergency  makes it
         impractical or  inadvisable to proceed with  completion of the offering
         or sale of and payment for the Offered Securities.

                  (c) The Purchasers shall have received an opinion,  dated such
         Closing Date, of Sullivan & Worcester,  counsel for the Company, to the
         effect set forth in Schedule D hereto.

                                       11



<PAGE>




                  (d) The Purchasers shall have received an opinion,  dated such
         Closing Date, of Dow, Lohnes & Albertson,  FCC counsel for the Company,
         to the effect set forth in Schedule E hereto.

                  (e)  The  Purchasers  shall  have  received  from  Sullivan  &
         Cromwell,  counsel for the Purchasers,  such opinion or opinions, dated
         such Closing Date,  with respect to the  incorporation  of the Company,
         the  validity of the Offered  Securities,  the Offering  Document,  the
         exemption  from  registra  tion for the offer  and sale of the  Offered
         Securities by the Company to the several  Purchasers and the resales by
         the several Purchasers as contemplated hereby and other related matters
         as CSFBC may  require,  and the Company  shall have  furnished  to such
         counsel such documents as they request for the purpose of enabling them
         to pass upon such matters.

                  (f) The Purchasers  shall have received a  certificate,  dated
         such Closing  Date, of the Chief  Executive  Officer of the Company and
         the Chief Financial  Officer of the Company in which such officers,  to
         the best of their knowledge after reasonable investigation, shall state
         that  the  representations  and  warranties  of  the  Company  in  this
         Agreement are true and correct,  that the Company has complied with all
         agreements  and satisfied all conditions on its part to be performed or
         satisfied  hereunder  at or  prior  to such  Closing  Date,  and  that,
         subsequent to the date of the most recent  financial  statements in the
         Offering  Document there has been no material  adverse change,  nor any
         development or event involving a prospective  material  adverse change,
         in the condition (financial or other), business,  properties or results
         of  operations  of the  Company and its  subsidiaries  taken as a whole
         except as set forth in or contemplated  by the Offering  Document or as
         described in such certificate.

                  (g) The  Purchasers  shall have received a letter,  dated such
         Closing Date, of Deloitte & Touche LLP which meets the  requirements of
         subsection (a) of this Section, except that the specified date referred
         to in such  subsection  will be a date not more than five days prior to
         such Closing Date for the purposes of this subsection.

                  (h) The Company and the  Depositary  shall have  executed  and
         delivered the Deposit Agreement (in form and substance  satisfactory to
         CSFBC) and the Deposit Agreement shall be in full force and effect.

                  (i) The  Depositary  shall  have  furnished  or  caused  to be
         furnished to the Purchasers a certificate  satisfactory to CSFBC of one
         of its  authorized  officers with respect to the deposit with it of the
         Offered  Preferred  Stock against  issuance of the Depositary  Receipts
         evidencing the Offered  Securities being sold on such Closing Date, the
         execution,  issuance,  countersignature and delivery of such Depositary
         Receipts  pursuant  to the  Deposit  Agreement  and such other  matters
         related thereto as CSFBC reasonably requests.

The Company  will  furnish the  Purchasers  with such  conformed  copies of such
opinions,  certificates,  letters and  documents  as the  Purchasers  reasonably
request.  CSFBC may in its sole  discretion  waive on  behalf of the  Purchasers
compliance with any conditions to the  obligations of the Purchasers  hereunder,
whether in respect of an Optional Closing Date or otherwise.

         7. Indemnification and Contribution. (a) The Company will indemnify and
hold harmless each Purchaser against any losses, claims, damages or liabilities,
joint or  several,  to which  such  Purchaser  may  become  subject,  under  the
Securities Act or the Exchange Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue  statement or alleged  untrue  statement  of any  material  fact
contained in the Offering Document,  or any amendment or supplement  thereto, or
any related preliminary  offering circular or the Exchange Act Reports, or arise
out of or are based upon the  omission or alleged  omission  to state  therein a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading, and will

                                       12



<PAGE>



reimburse each Purchaser for any legal or other expenses  reasonably incurred by
such  Purchaser in  connection  with  investigating  or defending any such loss,
claim,  damage,  liability or action as such  expenses are  incurred;  provided,
however, that the Company will not be liable in any such case to the extent that
any such  loss,  claim,  damage or  liability  arises out of or is based upon an
untrue  statement or alleged untrue statement in or omission or alleged omission
from any of such  documents  in reliance  upon and in  conformity  with  written
information furnished to the Company by any Purchaser through CSFBC specifically
for use therein,  it being  understood and agreed that the only such information
consists of the information described as such in subsection (b) below.

                  (b) Each Purchaser  will  severally and not jointly  indemnify
and hold harmless the Company against any losses, claims, damages or liabilities
to which  the  Company  may  become  subject,  under the  Securities  Act or the
Exchange  Act  or  otherwise,   insofar  as  such  losses,  claims,  damages  or
liabilities  (or actions in respect  thereof) arise out of or are based upon any
untrue  statement or alleged untrue  statement of any material fact contained in
the Offering Document,  or any amendment or supplement  thereto,  or any related
pre liminary offering  circular,  or arise out of or are based upon the omission
or the alleged  omission to state therein a material fact  necessary in order to
make the statements  therein, in the light of the circumstances under which they
were made, not misleading,  in each case to the extent,  but only to the extent,
that such untrue  statement or alleged  untrue  statement or omission or alleged
omission was made in reliance  upon and in conformity  with written  information
furnished to the Company by such Purchaser  through CSFBC  specifically  for use
therein,  and will reimburse any legal or other expenses  reasonably incurred by
the Company in connection with investi gating or defending any such loss, claim,
damage,  liability or action as such expenses are incurred,  it being understood
and agreed that the only such information furnished by any Purchaser consists of
the following  information in the Offering Document  furnished on behalf of each
Purchaser:  the last  paragraph at the bottom of the cover page  concerning  the
terms of the offering by the Purchasers,  the legend concerning  over-allotments
and  stabilizing  on the inside front cover page and the  material  relationship
disclosure  appearing  in  the  ninth  paragraph  under  the  caption  "Plan  of
Distribution".

                  (c) Promptly after receipt by an indemnified  party under this
Section of notice of the  commencement  of any action,  such  indemnified  party
will, if a claim in respect thereof is to be made against the indemnifying party
under  subsection  (a)  or (b)  above,  notify  the  indemnifying  party  of the
commencement  thereof; but the omission so to notify the indemnifying party will
not relieve it from any  liability  which it may have to any  indemnified  party
otherwise  than under  subsection  (a) or (b) above.  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 wish, jointly with any other indemnifying
party  similarly  notified,   to  assume  the  defense  thereof,   with  counsel
satisfactory to such  indemnified  party (who shall not, except with the consent
of the  indemnified  party,  be counsel to the  indemnifying  party),  and after
notice from the indemnifying  party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party will not be liable to such
indemnified   party  under  this  Section  for  any  legal  or  other   expenses
subsequently  incurred by such indemnified  party in connection with the defense
thereof other than reasonable  costs of  investigation.  No  indemnifying  party
shall,  without the prior written consent of the indemnified  party,  effect any
settlement  of any  pending  or  threatened  action  in  respect  of  which  any
indemnified  party is or could have been a party and  indemnity  could have been
sought  hereunder by such indemnified  party unless such settlement  includes an
unconditional release of such indemnified party from all liability on any claims
that are the subject matter of such action.

                  (d) If the  indemnification  provided  for in this  Section is
unavailable  or  insufficient  to  hold  harmless  an  indemnified  party  under
subsection (a) or (b) above,  then each  indemnifying  party shall contribute to
the amount paid or payable by such indemnified  party as a result of the losses,
claims, damages or liabilities referred to in subsection (a) or (b) above (i) in
such proportion as is appropriate to reflect the relative  benefits  received by
the Company on the one hand and the Purchasers on the other from the offering of
the Offered Securities or (ii) if the allocation provided by clause (i) above 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 Purchasers on the other in
connection with the statements

                                       13



<PAGE>



or omissions  which resulted in such losses,  claims,  damages or liabilities as
well as any other  relevant  equitable  considerations.  The  relative  benefits
received by the Company on the one hand and the Purchasers on the other shall be
deemed to be in the same  proportion as the total net proceeds from the offering
(before deducting  expenses) received by the Company bear to the total discounts
and  commissions  received  by  the  Purchasers  from  the  Company  under  this
Agreement.  The relative  fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged  omission to state a material  fact  relates to  information
supplied by the Company or the  Purchasers  and the  parties'  relative  intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
untrue  statement  or  omission.  The amount paid by an  indemnified  party as a
result of the losses,  claims,  damages or liabilities  referred to in the first
sentence  of this  subsection  (d) shall be deemed to include any legal or other
expenses  reasonably  incurred  by such  indemnified  party in  connection  with
investigating  or  defending  any action or claim  which is the  subject of this
subsection  (d).  Notwithstanding  the  provisions  of this  subsection  (d), no
Purchaser  shall be required to contribute any amount in excess of the amount by
which  the total  price at which the  Offered  Securities  purchased  by it were
resold exceeds the amount of any damages which such Purchaser has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged  omission.  The  Purchasers'  obligations  in this  subsection (d) to
contribute are several in proportion to their  respective  purchase  obligations
and not joint.

                  (e) The obligations of the Company under this Section shall be
in addition to any  liability  which the  Company may  otherwise  have and shall
extend, upon the same terms and conditions, to each person, if any, who controls
any Purchaser  within the meaning of the Securities Act or the Exchange Act; and
the obligations of the Purchasers under this Section shall be in addition to any
liability  which the respective  Purchasers may otherwise have and shall extend,
upon the same terms and  conditions,  to each  person,  if any, who controls the
Company within the meaning of the Securities Act or the Exchange Act.

         8. Default of  Purchasers.  If any Purchaser or  Purchasers  default in
their obligations to purchase Offered  Securities  hereunder on either the First
Closing Date or any Optional  Closing Date and the  aggregate  number of Offered
Securities  that such  defaulting  Purchaser or Purchasers  agreed but failed to
purchase does not exceed 10% of the total number of Offered  Securities that the
Purchasers  are  obligated  to purchase  on such  Closing  Date,  CSFBC may make
arrangements  satisfactory  to the  Company  for the  purchase  of such  Offered
Securities by other  persons,  including any of the  Purchasers,  but if no such
arrangements are made by such Closing Date, the non-defaulting  Purchasers shall
be obligated severally, in proportion to their respective commitments hereunder,
to purchase the Offered  Securities that such defaulting  Purchasers  agreed but
failed to purchase on such  Closing  Date.  If any  Purchaser or  Purchasers  so
default and the  aggregate  number of Offered  Securities  with respect to which
such  default or defaults  occur  exceeds  10% of the total  number of shares of
Offered Securities that the Purchasers are obligated to purchase on such Closing
Date and arrangements satisfac tory to CSFBC and the Company for the purchase of
such Offered Securities by other persons are not made within 36 hours after such
default,  this  Agreement will  terminate  without  liability on the part of any
non-defaulting  Purchaser  or the  Company,  except  as  provided  in  Section 9
(provided that if such default occurs with respect to Optional  Securities after
the First  Closing  Date,  this  Agreement  shall not  terminate  as to the Firm
Securities or any Optional Securities  purchased prior to such termination).  As
used in this Agreement, the term "Purchaser" includes any person substituted for
a  Purchaser  under this  Section.  Nothing  herein  will  relieve a  defaulting
Purchaser from liability for its default.

         9. Survival of Certain Representations and Obligations.  The respective
indemnities, agreements, representations, warranties and other statements of the
Company  or its  officers  and of the  several  Purchasers  set forth in or made
pursuant to this Agreement  will remain in full force and effect,  regardless of
any investigation,  or statement as to the results thereof, made by or on behalf
of any  Purchaser,  the  Company  or any of  their  respective  representatives,
officers or directors or any controlling  person,  and will survive  delivery of
and payment for the Offered Securities. If this Agreement is terminated pursuant
to Section 8 or if for any reason the purchase of the Offered  Securities by the
Purchasers  is not  consummated,  the Company shall remain  responsible  for the
expenses to be paid or reimbursed by it pursuant to Section 5 and the respective
obligations

                                       14



<PAGE>



of the Company and the  Purchasers  pursuant to Section 7 shall remain in effect
and if any Offered Securities have been purchased  hereunder the representations
and  warranties  in  Section 2 and all  obligations  under  Section 5 shall also
remain in effect. If the purchase of the Offered Securities by the Purchasers is
not  consummated  for any reason other than solely because of the termination of
this Agreement  pursuant to Section 8 or the occur rence of any event  specified
in clause  (iii),  (iv) or (v) of Section 6(b),  the Company will  reimburse the
Purchasers for all out-of-pocket  expenses  (including fees and disbursements of
counsel)  reasonably  incurred by them in  connection  with the  offering of the
Offered Securities.

         10. Notices.  All  communications  hereunder will be in writing and, if
sent to the Purchasers will be mailed, delivered or telegraphed and confirmed to
the Purchasers,  c/o CS First Boston  Corporation,  Park Avenue Plaza, New York,
N.Y. 10055,  Attention:  Investment  Banking  Department--Transactions  Advisory
Group, or, if sent to the Company, will be mailed,  delivered or telegraphed and
confirmed to it at 116 Huntington Avenue, Boston, MA 02116, Attention: Steven B.
Dodge;  provided,  however, that any notice to a Purchaser pursuant to Section 7
will be mailed, delivered or telegraphed and confirmed to such Purchaser.

         11.  Successors.  This  Agreement  will inure to the  benefit of and be
binding  upon  the  parties  hereto  and  their  respective  successors  and the
controlling  persons referred to in Section 7, and no other person will have any
right or obligation hereunder, except that holders and prospective purchasers of
Offered Securities,  Offered Preferred Stock, Exchange Debentures and Underlying
Shares shall be entitled to enforce the agreements  for their benefit  contained
in the second and third  sentences of Section 5(b) hereof against the Company as
if such holders were parties hereto.

         12.  Counterparts.  This  Agreement  may be  executed  in any number of
counterparts,  each of which  shall be  deemed to be an  original,  but all such
counterparts shall together constitute one and the same Agreement.

         13.  Applicable Law. This Agreement shall be governed by, and construed
in  accordance  with,  the  laws of the  State  of New York  without  regard  to
principles of conflicts of laws.

         The Company hereby  submits to the  non-exclusive  jurisdiction  of the
Federal and state  courts in the Borough of Manhattan in The City of New York in
any suit or  proceeding  arising  out of or relating  to this  Agreement  or the
transactions contemplated hereby.

                    Letter of Independent Public Accountants
                           Referred to in Section 6(a)


                           (i) they have performed the  procedures  specified by
                  the American  Institute of Certified Public  Accountants for a
                  review  of  interim  financial  information  as  described  in

                           included in the Offering  Document or in the Exchange

                  except  where  the  failure  to  be  so  qualified  would  not
                  individually  have a material adverse effect on the Company or

Offered Securities or the Offered Preferred Stock by the Company or the issuance
and  delivery of the  Exchange  Debentures  or the  Underlying  Shares,  and the
compliance with the terms and provisions  thereof,  the offering  thereof by the
Purchasers,  the  effectiveness  of  the  Credit  Agreement  Amendment  and  the
execution,  delivery and performance of the Indenture, the Deposit Agreement and
this Agreement;

         (ii) The  execution,  delivery  and  performance  by the Company of the
Indenture,  the  Deposit  Agreement,  this  Agreement  and the Credit  Agreement
Amendment  and the issuance and sale of the Offered  Securities  and the Offered
Preferred Stock and the issuance and delivery of the Exchange Debentures and the
Underlying  Shares and the compliance  with the respective  terms and provisions
thereof,  and the offering thereof by the Purchasers,  do not violate any of the
terms or provisions of (i) the  Communications Act or (ii) those radio broadcast
licenses that are held by the Company or any subsidiary of the Company;

         (iii)  Neither the Offering  Document nor the Exchange Act Report as of
the date of the Offering  Document  and as of the date  hereof,  with respect to
statements of federal broadcast  communications  law or legal conclusions solely
with  respect to  federal  broadcast  communications  law  contained  any untrue
statement of a material fact or omitted to state any material fact  necessary in
order to make such  statements  or  conclusions,  in light of the  circumstances
under which they were made, not misleading;

         (iv) The statements set forth under "Risk Factors - Factors Relating to
American and its Business Regulatory Matters" and "Business - Federal Regulation
of Radio  Broadcasting"  in the portion of the Offering  Document  preceding the
Annexes and in "Business - Federal Regulation of Radio  Broadcasting" in Annex A
of the  Offering  Document,  insofar  as they are,  or refer to,  statements  of
federal  broadcast  communications  law, or legal  conclusions  with  respect to
federal  broadcast  communications  law,  have been  reviewed  by us and,  taken

knowledge  (a) there is no  administrative  proceeding  pending  before  the FCC
against the radio broadcast stations described in the Offering Document as being
licensed to the Company or a  subsidiary  of the Company  which,  if  determined
adversely,  could  reasonably be expected to have a material adverse effect upon
any of the  Company's  radio  broadcast  stations,  and (b) the radio  broadcast
licenses issued by the FCC for such radio  broadcast  stations are in full force
and effect in that,  except as may be described in the Offering  Document,  they
are held by a subsidiary  of the Company,  are  currently  effective and are not
subject  to any  special  conditions  (other  than  those  conditions  of a type
customarily  imposed under the general  rules,  regulations  and policies of the
FCC) that would  materially  and  adversely  affect the  operation of such radio
broadcast stations as currently operated.

described  in the  Confidential  Offering  Circular  (the  "Offering  Circular")
relating to the offering.

         We hereby confirm that:

                  (i) we are an "accredited investor" within the meaning of Rule
         501(a)(1), (2) or (3) under the Securities Act of 1933, as amended (the
         "Securities  Act"), or any entity in which all of the equity owners are
         accredited  investors within the meaning of Rule 501(a)(l),  (2) or (3)
         under the Securities Act (an "Institutional Accredited Investor");

                  (ii) (A) any purchase of the  Securities by us will be for our
         own  account  or for the  account  of one or more  other  Institutional
         Accredited  Investors  or a  fiduciary  for the  account of one or more
         trusts, each of which is an "accredited investor" within the meaning of
         Rule  501(a)(7)  under  the  Securities  Act and for  each of  which we
         exercise sole investment  discretion or (B) we are a "bank", within the
         meaning of Section  3(a)(2) of the  Securities  Act, or a "savings  and
         loan association" or other institution  described in Section 3(a)(5)(A)
         of the Securities  Act, that is acquiring the Securities as a fiduciary
         for the account of one or more  institutions for which we exercise sole
         investment discretion;

                  (iii) in the event that we purchase any of the Securities,  we
         will acquire  Securities  having a minimum  purchase  price of not less
         than $100,000 for our own account or for any separate account described
         above for which we are acting;

                  (iv) we have  acknowledge  and  experience  in  financial  and
         business matters that we are capable of evaluating the merits and risks
         of purchasing the Securities;

                  (v)  we are  not  acquiring  the  Securities  with  a view  of
         distribution  thereof or with any  present  intention  of  offering  or
         selling  any of the  Securities,  except in  accordance  with Rule 144A
         under the Securities Act or in offshore transactions in accordance with

                  (vi) we have received a copy of the Offering Circular relating
         to the  offering of the  Securities  and  acknowledge  that we have had
         access to such financial and other information,  and have been afforded
         the opportunity to ask such questions of  representatives of the Issuer
         and receive  answers  thereto,  as we deem necessary in connection with
         our decision to purchase the Securities.

         We understand  that the  Securities  are being offered in a transaction
not involving any public offering within the Untied States within the meaning of
the  Securities  Act and  that  the  Securities  have  not  been and will not be
registered  under the Securities Act or any state  securities law, and we agree,
on our own  behalf  and on  behalf of each  account  for  which we  acquire  any
Securities,  that if in the  future  we decide to  resell,  pledge or  otherwise
transfer such  Securities,  such Securities may be offered,  resold,  pledged or
otherwise  transferred  only  (i) to a person  who we  reasonably  believe  is a
"qualified  institutional  buyer" (as defined in Rule 144A under the  Securities
Act) in a transaction meeting the requirements of Rule 144A, (ii) in an offshore
transaction meeting the requirements of Rule 904 under the Securities Act, (iii)
pursuant to an exemption from registration  under the Securities Act provided by
Rule 144 thereunder (if available),  (iv) pursuant to an effective  registration
statement  under the Securities Act, or (v) to the Issuer and (vi) in each case,
in accordance  with any  applicable  securities  laws of any State of the United
States  or other  applicable  jurisdiction.  We agree to notify  any  purchaser,
pledgee or transferee of such Securities of the restrictions  referred to in (i)
through (vi) above.  We understand that the registrar and transfer agent for the
Securities  will not be required  to accept for  registration  of  transfer  any
Securities acquired by us, except upon presentation of evidence  satisfactory to
the Issuer and the transfer  agent that the foregoing  restrictions  on transfer
have been complied with. We further  understand that any Securities  acquired by
us (other than pursuant to Rule 144A) will be in the form of definitive physical
certificates  and that  such  certificates  will  bear a legend  reflecting  the
substance of this paragraph.

         We  acknowledge  that you,  the Issuer  and  others  will rely upon our
confirmations, acknowledgements and agreements set forth herein, and we agree to
notify  you  promptly  in writing if any of our  representations  or  warranties
herein cease to be accurate and complete.

         THIS LETTER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF
CONFLICTS OF LAWS.

         The Trustee  may  appoint an  authenticating  agent  acceptable  to the
Issuer  to  authenticate  Securities.   Unless  limited  by  the  term  of  such
appointment,  an authenticating  agent may authenticate  Securities whenever the
Trustee may do so. Each  reference in this  Indenture to  authentication  by the
Trustee includes  authentication by such agent. An authenticating  agent has the
same rights as an Agent to deal with the Issuer or an Affiliate of the Issuer.

         The  Securities  shall be  issuable  only in regis  tered form  without
coupons and only in denominations of $1,000 and any integral multiple thereof.

         SECTION 2.3 Registrar,  Paying Agent and Conver sion Agent.  The Issuer
shall maintain in The Borough of Manhattan in The City of New York, New York, an
office or agency where  Securities may be presented for registration of transfer
or for  exchange  ("Registrar"),  an  office  or  agency  where  Securities  may
presented for payment ("Paying Agent"), an office or agency where Securities may
be presented for conversion  ("Conversion  Agent") and an office or agency where
notices and demands to or upon the Issuer in respect of the  Securities and this
Indenture may be served.  The Registrar  shall keep a register of the Securities
and of  their  transfer  and  exchange.  The  Issuer  may  appoint  one or  more
co-Registrars,  one or more additional  Paying Agents and one or more additional
Conversion Agents, which may be inside or outside The Borough of Manhattan.  The
term "Registrar" includes any co-Registrar, the term "Paying Agent" includes any
additional Paying Agent and the term "Conversion  Agent" includes any additional
Conversion  Agent.  The  Issuer  may  change  any  Registrar,  Paying  Agent  or
Conversion Agent without notice to any Holder. If the Issuer fails to appoint or
maintain  another  person as Registrar,  Paying Agent or Conversion  Agent,  the
Trustee shall act as such.  The Issuer or any Affiliate of the Issuer may act as
Registrar or Conversion  Agent.  Except for purposes of Article Nine, the Issuer
or any Affiliate of the Issuer may act as Paying Agent.

Agent  not a  party  to  this  Indenture.  The  agreement  shall  implement  the
provisions  of this  Indenture  that  relate to such  Agent.  The  Issuer  shall
promptly  notify the Trustee of the name and address of any Agent not a party to
this  Indenture.  If the Issuer  fails to maintain a  Registrar,  Paying  Agent,
Conversion  Agent or agent for service of notices and demands,  or fails to give
the foregoing notice, the Trustee shall act as such.


                                      -13-

         The Issuer initially  appoints the Trustee as Registrar,  Paying Agent,
Conversion Agent and agent for service of notices and demands.

         SECTION  2.4 Paying  Agent to Hold Money in Trust.  Not later than each
due date of the  principal  of or interest on any  Securities,  the Issuer shall
deposit  with the Paying  Agent a sum of money in  immediately  available  funds
sufficient to pay such principal or interest so becoming due. Subject to Section
9.2, the Paying Agent shall hold in trust for the benefit of  Securityholders or
the Trustee all money held by the Paying  Agent for the payment of  principal of
or interest on the  Securities,  and shall  notify the Trustee of any default by
the Issuer in making any such  payment.  If the  Issuer or an  Affiliate  of the
Issuer  acts as  Paying  Agent,  it  shall  on or  before  each  due date of the
principal of or interest on any Securities  segregate the money and hold it as a
separate  trust fund.  The Issuer at any time may require a Paying  Agent to pay
all money held by it to the Trustee,  and the Trustee may at any time during the
continuance of any default, upon written request to a Paying Agent, require such
Paying Agent to  forthwith  pay to the Trustee all sums so held in trust by such
Paying Agent. Upon doing so, the Paying Agent (other than the Issuer) shall have
no further liability for the money.

         SECTION 2.5 Holder Lists.  The Trustee  shall  preserve in as current a
form as is reasonably  practicable  the most recent list  available to it of the
names and  addresses of the Holders.  If the Trustee is not the  Registrar,  the
Issuer shall promptly  furnish to the Trustee on or before each interest payment
date and at such other  times as the  Trustee  may  request in writing a list in
such form and as of such date as the  Trustee  may  reasonably  require  for the
names and addresses of the Holders.

         SECTION 2.6 Transfer and Exchange.  When a Security is presented to the
Registrar  with a request to register a transfer  thereof,  the Registrar  shall
register the transfer as requested,  and, when  Securities  are presented to the
Registrar  with a request  to  exchange  them for an equal  principal  amount of
Securities  of other  authorized  denominations,  the  Registrar  shall make the
exchange as requested; provided that every Security presented or surrendered for
registration of transfer or exchange shall be duly endorsed or be accompanied by
a written  instrument  of  transfer in form  satisfactory  to the Issuer and the
Registrar duly executed by the Holder thereof or his attorney duly authorized in
writing.  To permit  registration  of transfers and exchanges,  the Issuer shall
execute and the Trustee shall authenticate Securities at the

                                      -14-



<PAGE>



Registrar's request. The Issuer shall not be required (i) to issue, register the
transfer of or exchange  Securities  during a period beginning at the opening of
business on a Business Day 15 days before the day of any selection of Securities
for redemption under Section 11.2 and ending at the close of business on the day
of  selection,  or (ii) to register  the transfer of or exchange any Security so
selected for redemption in whole or in part,  except the  unredeemed  portion of
any Security  being  redeemed in part. Any exchange or transfer shall be without
charge,  except that the Issuer may require payment of a sum sufficient to cover
any tax or other  governmental  charge that may be imposed in relation  thereto,
but this  provision  shall not apply to any exchange  pursuant to Section 7.5 or
11.2. Prior to due presentment for registration of transfer of any Security, the
Trustee,  any Agent and the  Issuer  may deem and treat the Person in whose name
any  Security is  registered  as the  absolute  owner of such  Security  for the
purpose of receiving  payment of principal of and interest on such  Security and
for all other purposes whatsoever,  whether or not such Security is overdue, and
none of the Trustee,  any Agent or the Issuer shall be affected by notice to the
contrary.

         SECTION  2.7  Replacement  Securities.   If  a  mutilated  Security  is
surrendered  to the  Trustee,  or if the  Holder of a Security  claims  that the
Security has been lost,  destroyed or wrongfully  taken,  and neither the Issuer
nor the Trustee has received  notice that such  Security has been  acquired by a
bona fide purchaser, the Issuer shall issue and the Trustee shall authenticate a
replacement  Security  if the  requirements  of  Section  8-405  of the New York
Uniform  Commercial  Code, as in effect on the date of this Indenture,  are met,
and there shall have been  delivered  to the Issuer and the Trustee  evidence to
their satisfaction of the loss,  destruction or theft of any Security if such is
the case.  An indemnity  bond may be required that is sufficient in the judgment
of the Issuer and the Trustee to protect  the  Issuer,  the Trustee or any Agent
from any loss which any of them may suffer if a Security is replaced. The Issuer
may charge the Holder for its expenses  (including  the fees and expenses of the
Trustee) in replacing a Security.  Every  replacement  Security is an additional
obligation of the Issuer.  The  provisions of this Section 2.7 are exclusive and
shall preclude all other rights and remedies with respect to the  replacement or
payment of mutilated, destroyed, lost or stolen Securities.

         SECTION 2.8 Outstanding  Securities.  The Securities Outstanding at any
time are all of the Securities  authenticated  by the Trustee,  except for those
canceled by

                                      -15-



<PAGE>



it, those delivered to it for  cancellation  and those described in this Section
2.8 as not Outstanding.

         If a Security  is  replaced  pursuant  to Section  2.7, it ceases to be
Outstanding  until  the  Trustee  receives  proof  satisfactory  to it that  the
replaced Security is held by a bona fide purchaser.

         If the  Paying  Agent  (other  than the Issuer or an  Affiliate  of the
Issuer) holds on a redemption date or maturity date money  sufficient to pay the
principal of and accrued  interest on Securities  payable on that date,  then on
and after that date such Securities cease to be Outstanding and interest on them
ceases to accrue.

         Subject to Section  6.4,  a Security  does not cease to be  Outstanding
because the Issuer or an Affiliate of the Issuer holds the Security.

         SECTION 2.9  Temporary  Securities.  Until defini tive  Securities  are
ready for  delivery,  the Issuer may prepare and,  upon the order of the Issuer,
the Trustee shall authenticate temporary Securities.  Temporary Securities shall
be  substantially  in the form of definitive  Securities but may have variations
that  the  Issuer  considers  appropri  ate for  temporary  Securities.  Without
unreasonable  delay, the Issuer shall prepare and the Trustee shall authenticate
definitive Securities in exchange for temporary Securities. Until such exchange,
temporary  Securities  shall  be  entitled  to the  same  rights,  benefits  and
privileges as definitive Securities.

         SECTION  2.10  Cancellation.   The  Issuer  at  any  time  may  deliver
Securities  to the Trustee for  cancellation.  The  Registrar,  Paying Agent and
Conversion Agent shall forward to the Trustee any Securities surrendered to them
for transfer, exchange, payment or conversion. The Trustee and no one else shall
cancel all Securities surrendered for transfer, exchange, payment, conversion or
cancellation.  The Issuer may not issue new Securities to replace  Securities it
has paid or  delivered  to the  Trustee  for  cancellation  or which  have  been
converted.  All  canceled  Securities  shall be held by the  Trustee  and may be
destroyed (and, if so destroyed,  certification  of their  destruction  shall be
delivered  to the  Issuer),  unless the Issuer  shall direct in writing that the
canceled Securities be returned to it.

         SECTION 2.11 Defaulted Interest. If the Issuer defaults in a payment of
interest on the  Securities,  it shall pay the defaulted  interest in any lawful
manner plus,

                                      -16-



<PAGE>



to the extent lawful, interest payable on the defaulted interest, to the persons
who are Holders on a  subsequent  special  record  date,  which date shall be at
least five  Business  Days prior to the payment  date,  in each case at the rate
provided  in the  Securities  and in Section  3.1.  The Issuer  shall,  with the
consent of the Trustee,  fix or cause to be fixed each such special  record date
and payment date. At least 15 days before a special  record date, the Issuer (or
the Trustee in the name of and at the  expense of the Issuer)  shall mail to the
Holders a notice that states the special record date,  the related  payment date
and the amount of such interest to be paid.

         SECTION 2.12 CUSIP  Numbers.  The Issuer in issuing the  Securities may
use "CUSIP"  numbers (if then  generally in use),  and, if so, the Trustee shall
use  "CUSIP"  numbers in notices of  redemption  as a  convenience  to  Holders;
provided that any such notice may state that no representation is made as to the
correctness  of such numbers either as printed on the Securities or as contained
in any notice of  redemption  and that  reliance may be placed only on the other
identification numbers printed on the Securities,  and any such redemption shall
not be affected by any defect in or omission of such numbers.

         SECTION  2.13  Transfer  Restrictions.  Securities  shall be stamped or
otherwise be imprinted with the legends containing the transfer restrictions set
forth on the face of the text of the  Securities  attached  as Exhibit A hereto.
The legends so provided on the face of the text of the Securities may be removed

years from the later of issuance of the  Security or the date such  Security (or
any  predecessor) was last acquired from an "affiliate" of the Issuer within the
meaning of Rule 144 under the Securities  Act or (ii) in connection  with a sale
made  pursuant  to the  volume  (and other  restrictions)  of Rule 144 under the
Securities Act following two years from such time,  provided that, if the legend
is removed and the  Security is  subsequently  held by such an  affiliate of the
Issuer, the legend shall be reinstated.

                                    COVENANTS

         SECTION 3.1 Payment of Principal and Interest. The Issuer covenants and
agrees that it will duly and  punctually  pay or cause to be paid the  principal
of, and  interest  on,  each of the  Securities  at the place or places,  at the
respective  times  and  in  the  manner  provided  in the  Securities  and  this
Indenture.  Each instalment of interest on the Securities may be paid by mailing
checks for such interest  payable to or upon the written order of the Holders of
Securities  entitled  thereto as they shall appear on the registry  books of the
Issuer.

         SECTION 3.2 Written  Statement  to Trustee.  The Issuer will deliver to
the  Trustee,  within 120 days after the end of each  fiscal  year of the Issuer
ending after the date  hereof,  an  Officers'  Certificate,  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 or  non-compliance  by
the Issuer in the perfor  mance or  fulfillment  of any  covenant,  agreement or
condition  contained  in  this  Indenture,  stating  whether  or not  they  have
knowledge of any such default or non-compliance (without regard to any period of
grace or requirement of notice provided hereunder),  and, if so, specifying each
such  default or  non-compliance  of which the signers  have  knowledge  and the
nature thereof.

         SECTION 3.3 Corporate  Existence.  Subject to Article Eight, the Issuer
will do or cause to be done all things  necessary  to preserve  and keep in full
force and effect its corporate existence,  rights and franchises;  provided that
the Issuer shall not be required to preserve its corporate existence or any such
right or franchise if the Issuer shall determine that the  preservation  thereof
is no longer  desirable in the conduct of its business and that the loss thereof
is not disadvantageous in any material respect to the Holders of the Securities.

         SECTION 3.4 Reports by the Issuer.  The Issuer  covenants  to file with
the  Trustee,  within 15 days after the Issuer is required to file the same with
the SEC,  copies of the annual reports and of the  information,  documents,  and
other reports (or copies of such portions of any of the foregoing as the SEC may
from time to time by rules and  regulations  prescribe)  which the Issuer may be
required  to file with the SEC  pursuant  to Section 13 or Section  15(d) of the
Exchange Act, or if the Issuer is not required to file  information,  documents,
or reports pursuant to either of

                                      -18-



<PAGE>



such  sections,  then to file with the  Trustee,  in  accordance  with rules and
regulations  prescribed from time to time by the SEC, such of the  supplementary
and periodic information,  documents, and reports which may be required pursuant
to  Section 13 of the  Exchange  Act;  or, in  respect of a security  listed and
registered on a national  securities  exchange or on NASDAQ as may be prescribed
from time to time in such rules and regulations.  At any time when the Issuer is
not subject to Section 13 or 15(d) of the Exchange  Act, upon request of Holders
and  prospective  purchasers of Securities or the Class A Common Stock  issuable
upon  conversion  thereof,  the  Issuer  will  promptly  furnish  or cause to be
furnished to such holders and prospective purchasers,  copies of the information
required to be  delivered  to such holders and  prospective  purchasers  of such
securities  pursuant  to  Rule  144A(d)(4)  under  the  Securities  Act  (or any
successor  provision  thereto) in order to permit  compliance  with Rule 144A in
connection with resales by such holders of such securities.  The Issuer will pay
the  expenses of  printing  and  distributing  to such  holders and  prospective
purchasers all such documents.

         SECTION  3.5  Waiver of Usury  Defense.  The Issuer  covenants  (to the
extent that it may lawfully do so) that it shall not assert, plead (as a defense
or otherwise) or in any manner  whatsoever  claim (and shall actively resist any
attempt  to  compel  it to  assert,  plead  or  claim)  in any  action,  suit or
proceeding that the interest rate on the Securities  violates  present or future
usury or other laws  relating to the interest  payable on any  Indebtedness  and
shall not  otherwise  avail  itself  (and shall  actively  resist any attempt to
compel it to avail itself) of the benefits or advantages of any such laws.

         SECTION  3.6  Payment of Excess  Cash  Dividends.  If the Issuer  shall
declare and pay cash  dividends on its Class A Common Stock in an annualized per
share amount which exceeds the greater of (i) the annualized per share amount of
the immediately preceding cash dividend on its Class A Common Stock (as adjusted
to reflect any of the events  listed in  Sections  13.4 or 13.5) and (ii) 15% of
the  Last  Sale  Price  of the  Class  A  Common  Stock  as of the  Trading  Day
immediately  preceding the date of  declaration  of such dividend (the per share
amount of any such per share  excess,  to the  extent of such per share  excess,
being  herein  called an "Excess  Amount"),  then in any such event the  Holders
shall have the right to receive, and the Issuer will pay to each such Holder, at
the time of the payment of such Class A Common Stock  dividend,  an amount equal
to such Excess Amount  (calculated on the basis of the number of shares of Class
A Common Stock that would have been issued to a Holder upon

                                      -19-

conversion  of the  Securities  held by such  Holder on the record  date for the
payment of such dividend)  unless the Holder converts and receives such dividend
as a holder of Class A Common Stock.

                           REMEDIES OF THE TRUSTEE AND
                       SECURITYHOLDERS ON EVENT OF DEFAULT

         SECTION 4.1 Event of Default Defined; Accelera tion of Maturity; Waiver
of Default.  "Event of Default"  with respect to  Securities  where used herein,
means  each  one of the  following  events  which  shall  have  occurred  and be
continuing  (whatever  the reason for such Event of Default and whether it shall
be occasioned by the provisions of Article Twelve or be voluntary or involuntary
or be effected by operation of law or pursuant to any judgment,  decree or order
of any  court  or any  order,  rule  or  regulation  of  any  administrative  or
governmental body):

                  (a) default in the payment of any  instalment of interest upon
         any of the  Securities  as and  when  the  same  shall  become  due and
         payable, and continuance of such default for a period of 30 days; or

                  (b) default in the payment of all or any part of the principal
         of or premium,  if any, upon any of the Securities as and when the same
         shall become due and payable either at maturity, upon any redemption or
         acceleration, by declaration or otherwise; or

                  (c)  failure  on the part of the  Issuer to observe or perform
         any other of the  covenants or  agreements on the part of the Issuer in
         the Securities or in this  Indenture  contained for a period of 60 days
         after the date on which written notice specifying such failure, stating
         that such notice is a "Notice of Default"  hereunder and demanding that
         the Issuer  remedy the same,  shall  have been given by  registered  or
         certified mail, return receipt requested, to the Issuer by the Trustee,
         or to the  Issuer  and the  Trustee  by the  Holders of at least 25% in
         aggregate principal amount of the Outstanding Securities; or

                  (d) a court having  jurisdiction in the premises shall enter a
         decree or order for relief in  respect of the Issuer in an  involuntary
         case or proceeding  under any applicable  Federal or State  bankruptcy,
         insolvency, reorganization or other similar law now or hereafter in

                                      -20-



<PAGE>



         effect,  or a decree  or order  adjudging  the  Issuer  a  bankrupt  or
         insolvent,   approving   as   properly   filed   a   petition   seeking
         reorganization, assignment, adjustment or composition of, or in respect
         of, the Issuer under any applicable  Federal or State law or appointing
         a receiver, liquidator,  assignee, custodian, trustee, sequestrator (or
         similar  official)  of the  Issuer or for any  substantial  part of its
         property or ordering the winding up or liquidation of its affairs,  and
         such decree or order shall  remain  unstayed and in effect for a period
         of 60 consecutive days; or

                  (e) the Issuer shall  commence a voluntary  case or proceeding
         under  any  applicable   Federal  or  State   bankruptcy,   insolvency,
         reorganization  or other similar law now or hereafter in effect, or any
         other case or proceeding to be adjudicated a bankrupt or insolvent,  or
         consent to the entry of an order for relief in an  involuntary  case or
         proceeding   under  any   applicable   Federal  or  State   bankruptcy,
         insolvency,  reorganization or other similar law or to the commencement
         of any  bankruptcy or insolvency  case or proceeding  against it, or to
         the  filing  by  it  of  a  petition  or  answer  or  consent   seeking
         reorganization or relief under any applicable  Federal or State law, or
         consent to the filing of such petition or to the  appointment or taking
         possession by a receiver, liquidator,  assignee, cus todian, trustee or
         sequestrator (or similar official) of the Issuer or for any substantial
         part of its prop erty, or make any general  assignment  for the benefit
         of creditors, or the admission by it in writing of its inability to pay
         its debts  generally  as they become  due,  or the taking of  corporate
         action by the Issuer in furtherance of any such action.

         If an Event of Default  occurs and is  continuing  with  respect to the
Securities,  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 the Securities
then  Outstanding  hereunder,  by notice in writing  to the  Issuer  (and to the
Trustee if given by  Securityholders),  may declare the entire  principal of all
the  Securities  and  the  interest  accrued  thereon,  to be  due  and  payable
immediately, and upon any such declaration the same shall become immediately due
and payable.  This provision,  however,  is subject to the condition that if, at
any time after the principal of the  Securities  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

                                      -21-



<PAGE>



shall pay or shall deposit with the Trustee a sum  sufficient to pay all matured
installments  of interest upon all the  Securities  and the principal of any and
all Securities 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 applicable law, on overdue  installments of interest,  at the
same rate as the rate of interest  specified in the  Securities,  to the date of
such  payment  or  deposit)  and such  amount  as shall be  sufficient  to cover
reasonable  compensation  to the Trustee  and each  predecessor  Trustee,  their
respective agents, attorneys and counsel, and all other expenses and liabilities
incurred,  and all advances  made, by the Trustee and each  predecessor  Trustee
except as a result of  negligence  or bad  faith,  and if any and all  Events of
Default under the Indenture,  other than the  non-payment of the interest on and
principal of Securities which shall have become due by acceleration,  shall have
been cured,  waived or otherwise remedied as provided  herein--then and in every
such case of such a cure the  Holders  of a  majority  in aggre  gate  principal
amount of the Securities then  Outstanding,  by written notice to the Issuer and
to the Trustee,  may waive all  defaults 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.

         SECTION 4.2 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 instalment of interest on any of the Securities  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 or premium,  if any, on any of the Securities  when the
same shall have  become  due and  payable,  whether  upon  maturity  or upon any
redemption or 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
the whole  amount  that then  shall  have  become  due and  payable  on all such
Securities for principal, premium, if any, 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
specified in the Securities);  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  and each  predecessor  Trustee,  their
respective  agents,  attorneys  and  counsel,  and any expense and liabili  ties
incurred,  and all advances  made, by the Trustee and each  predecessor  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  premium,  if  any,  and  interest  on the  Securities  to the
registered Holders, whether or not the Securities 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 Securi
ties and collect in the manner provided by law out of the property of the Issuer
or other obligor upon the Securities,  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  under Title 11 of the United States Code
or any other applicable Federal or state bankruptcy, insolvency,  reorganization
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 other obligor upon the Securities,  or to the creditors or property of
the Issuer or such other  obligor,  the  Trustee,  irrespective  of whether  the
principal of the Securities  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 principal, premium, if any, and interest owing and unpaid in respect
         of the Securities, and to file such other papers or documents as may be
         necessary  or  advisable  in order to have the  claims of the  Trustees
         (including  any claim for  reasonable  compensation  to the Trustee and
         each predecessor  Trustee,  and their respective agents,  attorneys and
         counsel,   and  for  reimbursement  of  all  expenses  and  liabilities
         incurred, and all advances made, by the

                                      -22-



<PAGE>



         Trustee and each predecessor Trustee,  except as a result of negligence
         or bad  faith)  and  of the  Securityholders  allowed  in any  judicial
         proceedings   relative  to  the  Issuer  or  other   obligor  upon  the
         Securities, 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  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,  or
         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,
         each  predecessor  Trustee and their respective  agents,  attorneys and
         counsel,  and all other  expenses  and  liabilities  incurred,  and all
         advances made, by the Trustee and each predecessor  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
Securityholder  any plan of reorganization,  arrangement,  adjustment or caption
affecting the  Securities or the rights of any Holder  thereof,  or to authorize
the  Trustee to vote in respect of the claim of any  Securityholder  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,  may be  prosecuted  and  enforced  by the Trustee
without the possession of any of the Securities 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

                                      -23-



<PAGE>



Trustee,  each predecessor  Trustee and their  respective  agents and attorneys,
shall be for the ratable benefit of the Holders of the Securities.

         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 in respect of which such action was taken, and it shall not be
necessary to make any Holders of the Securities parties to any such proceedings.

         SECTION  4.3  Application  of  Proceeds.  Any moneys  collected  by the
Trustee  pursuant to this Article in respect of  Securities  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  stamping  (or  otherwise  noting)
thereon the  payment,  or issuing  Securities  in reduced  principal  amounts in
exchange for the presented  Securities if only partially paid, or upon surrender
thereof if fully paid:

               FIRST:  To the payment of costs and  expenses,  including any and
          all amounts due the Trustee  under  Section  5.5;  

               SECOND:  Subject to Article Twelve herein,  in case the principal
          of the  Securities  shall not have become and be then due and payable,
          to the payment of interest on the  Securities  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  specified  in the  Securities,  such  payments to be made
          ratably to the person  entitled  thereto,  without  discrimination  or
          preference;

               THIRD: Subject to Article Twelve herein, in case the principal of
          the Securities shall have become and shall be then due and payable, to
          the  payment of the whole  amount  then owing and unpaid  upon all the
          Securities for principal, premium, if any, and interest, with interest
          upon the overdue  principal  and  premium,  if any, 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
          specified  in the  Securities;  and  in  case  such  moneys  shall  be
          insufficient  to pay in full the whole  amount so due and unpaid  upon
          the Securities,

                                      -24-

         then to the payment of such principal,  premium,  if any, and interest,
         without preference or priority of principal (and premium,  if any) over
         interest,  or of interest over principal  (and premium,  if any), or of
         any instalment of interest over any other instalment of interest, or of
         any Security over any other Security,  ratably to the aggregate of such
         principal, premium, if any, 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  4.4 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 4.5  Restoration of Rights or Abandonment  of  Proceedings.  In
case the Trustee or any Securityholder 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
or to  such  Securityholder,  then  and  in  every  such  case,  subject  to any
determination   in  such   proceeding,   the   Issuer,   the   Trustee  and  the
Securityholders  shall be restored  severally and  respectively  to their former
positions and rights hereunder,  and thereafter all rights,  remedies and powers
of the Issuer, the Trustee and the  Securityholders  shall continue as though no
such proceedings had been taken.

         SECTION 4.6 Limitations on Suits by Security holders.  No Holder of any
Security  shall have any right by virtue or by availing of any provision of this
Indenture to institute any action or proceeding,  judicial or otherwise,  at law
or in equity or in bankruptcy or otherwise upon or under or with respect to this
Indenture, or for the appoint ment 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 a continuing Event
of Default as herein before provided, and unless also the Holders of not less

                                      -25-



<PAGE>



than 25% in aggregate  principal amount of the securities then Outstanding 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 45 days
after its  receipt of such  notice,  request and offer of  indemnity  shall have
failed to institute any such action or proceedings and no direction inconsistent
with such  written  request  shall have been given to the  Trustee  pursuant  to
Section 4.9; it being understood and intended, and being expressly covenanted by
the Holder of every  Security with every other Holder of the  Securities and the
Trustee,  that no one or more Holders of Securities  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 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.  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  4.7  Unconditional   Right  of  Security  holders  to  Receive
Principal,  Premium and  Interest,  to Convert and to Institute  Certain  Suits.
Notwithstanding  any other  provision in this Indenture and any provision of any
Security, the right, subject to Article 12 herein, of any Holder of any Security
to receive payment of the principal of and premium, if any, and interest on such
Security on or after the respective due dates expressed in such Security (or, in
the case of redemption,  on the Redemption Date), or to convert such Security in
accordance  with Article  Thirteen,  or to institute suit for the enforcement of
any such payment on or after such  respective  dates,  or for the enforcement of
such conversion right,  shall not be impaired or affected without the consent of
such Holder.

         SECTION  4.8 Powers and  Remedies  Cumulative;  Delay or  Omission  Not
Waiver of Default. Except as provided in Sections 2.7, no right or remedy herein
conferred upon or reserved to the Trustee or to the  Securityholders 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

                                      -26-



<PAGE>



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 any of the
Securities  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 4.6, every power and remedy given
by this  Indenture  or by law to the  Trustee or to the  Securityholders  may be
exercised from time to time, and as often as shall be deemed  expedient,  by the
Trustee or by the Securityholders, as the case may be.

         SECTION  4.9 Control by  Securityholders.  The Holders of a majority in
aggregate  principal amount of the Securities at the time Outstanding shall have
the right to direct the time, method, and place of conducting any proceeding for
any remedy available to the Trustee,  or exercising any trust or power conferred
on the Trustee;  provided  that 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 5.1) 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 expose
the Trustee to personal  liability  or if the Trustee in good faith by its board
of directors or the  executive  committee  thereof  shall so determine  that the
actions or  forbearances  specified  in or pursuant to such  direction  would be
unduly  prejudicial to the interests of Holders of the Securities not joining in
the giving of said direction,  it being understood that (subject to Section 5.1)
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 by Securityholders.

         SECTION 4.10 Waiver of Past Defaults.  Prior to the  declaration of the
maturity of the Securities as provided in Section 4.1, the Holders of a majority
in aggregate  principal  amount of the Securities at the time Outstanding may on
behalf of the Holders of all the  Securities  waive any past default or Event of
Default  hereunder  and its  consequences,  except a  default  in  respect  of a
covenant or provision hereof which cannot be modified

                                      -27-



<PAGE>



or  amended  without  the  consent  of the  Holder  of  each  Security  affected
(including,  without  limitation,  the  provisions  with  respect  to payment of
principal of and premium,  if any, and interest on such Security or with respect
to conversion of such Security).

         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  4.11  Trustee to Give Notice of Default,  But May  Withhold in
Certain Circumstances.  The Trustee shall, at the Issuer's expense,  transmit to
the Holders of Securities,  as the names and addresses of such Holders appear on
the registry  books,  notice by mail of all defaults known to the Trustee,  such
notice to be  transmitted  within 90 days after the occurrence  thereof,  unless
such  defaults  shall have been cured before the giving of such notice (the term
"default" or "defaults" for the purposes of this Section 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 premium, if any, or interest on any of the
Securities,  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.

         SECTION  4.12 Right of Court to Require  Filing of  Undertaking  to Pay
Costs.  All parties to this Indenture  agree, and each Holder of any Security 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 other
than the Trustee 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 including the Trustee,
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

                                      -28-



<PAGE>



instituted  by any  Securityholder  or group of  Securityholders  holding in the
aggregate more than 10% in aggregate  princi pal amount of the Securities at the
time  Outstanding,  or to any  suit  instituted  by any  Securityholder  for the
enforcement of the payment of the principal of or interest on any Security on or
after the due date expressed in such Security or for the  enforcement of a right
to convert any Security in accordance with Article Thirteen.

         SECTION 4.13 Waiver of Stay or Extension Laws. The Issuer covenants (to
the extent that it may lawfully do so) that it will not at any time insist upon,
or plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay or extension  law  wherever  enacted,  now or at any time  hereafter in
force, which may affect the covenants or the performance of this Indenture;  and
the Issuer (to the extent that it may  lawfully do so) hereby  expressly  waives
all benefit or advantage of any such law and covenants  that it will not hinder,
delay or impede the  execution of any power herein  granted to the Trustee,  but
will suffer and permit the  execution  of every such power as though no such law
had been enacted.

                             CONCERNING THE TRUSTEE

         SECTION 5.1 Duties and Responsibilities of the Trustee; During Default;
Prior to Default.  With respect to the Holders of Securities  issued  hereunder,
the Trustee, prior to the occurrence of an Event of Default and after the curing
or  waiving  of all Events of Default  which may have  occurred,  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  has
occurred  (which has not been cured or waived),  the Trustee shall exercise 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 or bad faith, except that

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


                                      -29-



<PAGE>



                           (i) the duties and  obligations  of the Trustee  with
                  respect  to  Securities  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 correct ness of the opinions  expressed
                  therein,   upon   any   resolution,    statement,    officer's
                  certificate,  or any other certificate,  instrument or opinion
                  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 the
         direction  of Holders  pursuant  to Section  4.9  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 ground for believing that the
repayment  of such funds or adequate  indemnity  against  such  liability is not
reasonably assured to it.

         SECTION 5.2 Certain Rights of the Trustee. Subject to Section 5.1:


                                      -30-



<PAGE>



                  (a) the Trustee may rely and shall be  protected  in acting or
         refraining from acting upon any resolu tion,  Officers'  Certificate or
         any other certificate,  statement, instrument, opinion, report, notice,
         request,  direction,  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 advice or
         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  Securityholders  pursuant  to the
         provisions of this Indenture,  unless such  Securityholders  shall have
         offered to the Trustee  reasonable  security or  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,
         suffered  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;

                  (f) prior to the  occurrence of an Event of Default  hereunder
         and after the curing or waiver of all 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  then
         Outstanding, but the Trustee, in its

                                      -31-



<PAGE>



         discretion,  may make such further inquiries or investigation into such
         facts or matters as it may see fit, and, if the Trustee shall determine
         to make such inquiry or investigation,  it shall be entitled to examine
         the books,  records and premises of the Issuer,  personally or by agent
         or attorney;  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  expenses  or  liabili  ties  as a
         condition  to  proceeding;   the  reasonable  expenses  of  every  such
         examination  shall be paid by the Issuer or, if paid by the  Trustee or
         any predecessor 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  5.3 Trustee  Not  Responsible  for  Recitals,  Disposition  of
Securities or Application of Proceeds Thereof. The recitals contained herein and
in the Securi ties, 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
Securi ties. 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 5.4 Trustee and Agents May Hold Securities;  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  with the same
rights it would have if it were not the  Trustee  or such agent and,  subject to
Section 5.8, may otherwise deal with the Issuer and receive,  collect,  hold and
retain collections from the Issuer with the same rights it would have if it were
not the Trustee or such agent.

         SECTION 5.5 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

                                      -32-



<PAGE>



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  and each  predecessor  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 and each predecessor  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 but not limited to the costs and expenses of
defending itself against or investigating  any claim or liability in connec tion
with the exercise or performance of any of its powers or duties  hereunder.  The
obligations  of the Issuer under this Section to  compensate  and  indemnify the
Trustee and each  predecessor  Trustee and to pay or  reimburse  the Trustee and
each  predecessor  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 payment of principal of
or interest on particular Securities, and the Securities are hereby subordinated
to such senior claim.  When the Trustee incurs  expenses or renders  services in
connection  with an Event of Default  specified in Section 4.1 or in  connection
with Article  Four  hereof,  the expenses  (including  the  reasonable  fees and
expenses of its  counsel)  and the  compensation  for the service in  connection
therewith  are  intended  to  constitute  expenses of  administration  under any
bankruptcy law.

         SECTION  5.6 Right of Trustee to Rely on  Officers'  Certificate,  etc.
Subject to Sections 5.1 and 5.2, 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 be conclusively  proved and established by an
Officers' Certificate delivered

                                      -33-



<PAGE>



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 upon the
faith thereof.

         SECTION 5.7 Persons  Eligible for  Appointment as Trustee.  The Trustee
hereunder shall at all times be a corporation organized and doing business under
the laws of the  United  States of America  or of any State or the  District  of
Columbia.  The Trustee and its direct  parent shall at all times have 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 5.8.

         SECTION 5.8 Resignation and Removal;  Appointment of Successor Trustee.
(a) The Trustee may at any time resign by giving  written  notice of resignation
to the Issuer.  Upon  receiving  such notice of  resignation,  the Issuer  shall
promptly  appoint a  successor  trustee  by  written  instrument  in  duplicate,
executed by authority  of the Board of  Directors,  one copy of each  instrument
shall be  delivered  to the  resigning  Trustee  and one  copy to the  successor
trustee.  If no successor trustee shall have been so appointed and have accepted
appointment  within 30 days after the giving of such notice of resignation,  the
resigning  trustee may  petition  any court of  competent  jurisdiction  for the
appointment of a successor  trustee,  or any Security holder who has been a bona
fide Holder of a Security or Securities for at least six months may,  subject to
the  provisions of Section  4.12, on behalf of himself 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) (1) At any time  prior to the  Exchange  Date or (2) if at any time
any of the following shall occur:


                                      -34-



<PAGE>



                (i) the  Trustee  shall fail to comply  with the pro  visions of
         Section  5.7 after  written  request  therefor  by the Issuer or by any
         Securityholder  who  has  been a bona  fide  Holder  of a  Security  or
         Securities for at least six months; or

               (ii) the Trustee  shall became  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;

then,  in any such case in (1) or (2)(i) or (ii),  the  Issuer  may  remove  the
Trustee and appoint a successor  trustee by written  instrument,  in  duplicate,
executed by order of the Board of  Directors  of the  Issuer,  one copy of which
instrument  shall be  delivered  to the  Trustee so removed  and one copy to the
successor trustee (provided that in the case of (1) such removal and appointment
of a successor must become  effective  prior to the Exchange  Date),  or, in the
case of (2)(i) or (ii) and  subject  to the  provisions  of  Section  4.12,  any
Securityholder  who has been a bona fide Holder of a Security or Securities  for
at least six months may on behalf of himself 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) The  Holders of a majority  in  aggregate  principal  amount of the
Securities  at the time  Outstanding  may at any time  remove  the  Trustee  and
appoint a successor  trustee by  delivering  to the  Trustee so removed,  to the
successor  trustee so appointed  and to the Issuer the evidence  provided for in
Section 6.1 of the action in that regard taken by the Securityholders.

         (d) Any  resignation or removal of the Trustee and any appointment of a
successor  trustee  pursuant to any of the  provisions of this Section 5.8 shall
become  effective upon  acceptance of  appointment  by the successor  trustee as
provided in Section 5.9.

         (e) The Issuer  shall give notice of each resigna tion and each removal
of the Trustee and each  appointment of a successor  trustee by mailing  written
notice of such event by first-class  mail,  postage  prepaid,  to the Holders of
Securities affected as their names and addresses appear in

                                      -35-



<PAGE>



the  Security  register,  provided  that if such  removal and  appointment  of a
successor  occurs prior to the Exchange  Date,  such notice shall be so given on
the Exchange Date.  Each notice shall include the name of the successor  trustee
and the address of its principal corporate trust office.

         SECTION  5.9  Acceptance  of  Appointment  by Succes sor  Trustee.  Any
successor trustee appointed as provided in Section 5.8 shall execute 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 shall become effective and such successor trustee,  without
any  further  act,  deed or  conveyance,  shall  become  vested with all rights,
powers, duties and obligations of its predecessor hereunder, with like effect as
if originally named as trustee herein; 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 9.4, pay over to
the  successor  trustee  all moneys at the time held by it  hereunder  and shall
execute and deliver an instrument  transferring  to such  successor  trustee all
such rights, powers, duties and obligations.  Upon request of any such successor
trustee,  the Issuer shall execute any and all  instruments  in writing for more
fully and certainly vesting in and confirming to such successor trustee all such
rights and powers.  Any  trustee  ceasing to act shall,  nevertheless,  retain a
prior claim upon all  property  or funds held or  collected  by such  trustee to
secure any amounts then due it pursuant to the provisions of Section 5.5.

         Upon  acceptance of appointment  by a successor  trustee as provided in
this Section 5.9, the Issuer shall mail notice  thereof by  first-class  mail to
the Holders of  Securities  at their last  addresses as they shall appear in 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 5.8. If
the  Issuer  fails to mail  such  notice  within  10 days  after  acceptance  of
appointment  by the successor  trustee,  the successor  trustee shall cause such
notice to be mailed at the expense of the Issuer.

         SECTION  5.10  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 cor porate trust  business of the
Trustee, shall be the successor

                                      -36-



<PAGE>



of the Trustee  hereunder  without the  execution  or filing of any paper or any
further act on the part of any of the  parties  hereto,  anything  herein to the
contrary notwithstanding; provided that such corporation shall be eligible under
the provisions of Section 5.7.

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


                                   ARTICLE SIX

                         CONCERNING THE SECURITYHOLDERS

         SECTION 6.1 Evidence of Action Taken by Security holders.  Any request,
demand,  authorization,  direction,  notice,  consent,  waiver  or other  action
provided  by this  Indenture  to be given or  taken  by  Securityholders  may be
embodied in and evidenced by one or more  instruments of  substantially  similar
tenor  signed by such  Securityholders  in person or by agent 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.  Proof of execution of any such  instrument or of a writing  appointing
any such  agent  shall be  sufficient  for any  purpose  of this  Indenture  and
(subject to  Sections  5.1 and 5.2)  conclusive  in favor of the Trustee and the
Issuer, if made in the manner provided in this Article.

         SECTION  6.2  Proof of  Execution  of  Instruments  and of  Holding  of
Securities.  Subject to Sections 5.1 and 5.2, the fact and date of the execution
of any instrument by any  Securityholder or his agent or proxy, or the authority
of such an agent or proxy to execute such an instrument may be

                                      -37-



<PAGE>



proved  (i)  by  the  affidavit  of a  witness  of  such  execution,  (ii)  by a
certificate  of a notary  public  (or other  officer  authorized  by law to take
acknowledgments of deeds) as to such execution, or (iii) in accordance with such
reasonable  rules and regulations as may be prescribed by the Trustee or in such
manner as shall be  reasonably  satisfactory  to the  Trustee.  The  holding  of
Securities  shall be proved by the Security  register or by a certificate of the
registrar thereof.

         SECTION 6.3 Holders to Be Treated as Owners.  Prior to due  presentment
of a Security for registration of transfer,  the Issuer, the Trustee,  any Agent
and any agent of the  Issuer  or the  Trustee  may deem and treat the  person in
whose name any Security  shall be registered  upon the Security  register 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  neither the Issuer nor the Trustee nor any Agent or 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.

         SECTION  6.4  Securities  Owned by Issuer  Deemed Not  Outstanding.  In
determining whether the Holders of the requisite principal amount of Outstanding
Securities  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  or any  Affiliate  of the Issuer or of such other  obligor  shall be
disregarded  and  deemed  not to be  Outstanding  for the  purpose  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.  Securi
ties so  owned  which  have  been  pledged  in good  faith  may be  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 the  Securities or any Affiliate of
the Issuer or of such other obligor.  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

                                      -38-



<PAGE>



Officers'  Certificate listing and identifying all Securi ties, 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 5.1 and 5.2, 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 purpose of any such determination.

         SECTION 6.5 Right of Revocation  of Action Taken.  At any time prior to
(but not after) the  evidencing  to the Trustee,  as provided in Section 6.1, of
the taking of any action by the Holders of the percentage in aggregate principal
amount of the  Securities  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 holding as provided in this  Article,
revoke such action so far as concerns  such  Security.  Except as afore said any
such action taken by the Holder of any Security  shall be conclusive and binding
upon such Holder and upon all future  Holders and owners of such Security and of
any Securities issued in exchange or substitution therefor or on registration or
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
percentage in aggregate  principal  amount of the  Securities  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.

         SECTION 6.6 Record Date for Consents  and Waivers.  The Issuer may, but
shall not be obligated to, direct the Trustee to establish a record date for the
purpose of determining  the Persons  entitled to (i) waive any past default with
respect to the Securities in accordance  with Section 4.10,  (ii) consent to any
supplemental  indenture in accordance with Section 7.2 or (iii) waive compliance
with  any  term,  condition  or  provision  of any  covenant  hereunder  (if the
Indenture should expressly provide for such waiver).  If a record date is fixed,
the Holders of Securities on such record date, or their duly designated proxies,
and any such Persons, shall be entitled to waive any such past default,  consent
to any such  supplemental  indenture  or waive  compliance  with any such  term,
condition or provision,  whether or not such Holder  remains a Holder after such
record date; provided,  however,  that unless such waiver or consent is obtained
from the Holders,  or duly designated proxies, of the requisite principal amount
of Outstanding

                                      -39-



<PAGE>



Securities  prior to the date which is the 90th day after such record date,  any
such waiver or consent previously given shall  automatically and without further
action by any Holder be cancelled and of no further effect.


                                  ARTICLE SEVEN

                             SUPPLEMENTAL INDENTURES

         SECTION 7.1 Supplemental Indentures Without Consent of Securityholders.
The Issuer,  when authorized by a resolution of its Board of Directors,  and the
Trustee  may from  time to time  and at any  time  enter  into an  indenture  or
indentures supplemental hereto for one or more of the following purposes:

               (a) to  convey,  transfer,  assign,  mortgage  or  pledge  to the
          Trustee as security for the Securities any property or assets;  

               (b) 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 Eight;

               (c) to add to the covenants of the Issuer such further covenants,
          restrictions,  conditions or provisions  (including without limitation
          provisions  necessary or desirable to qualify this Indenture under the
          Trust Indenture Act of 1939, or any successor statute,  as may then be
          in effect) as its Board of Directors and the Trustee shall consider to
          be for the protection or benefit of the Holders of Securities,  and to
          make the occurrence,  or the occurrence and continu ance, of a default
          in  any  such  additional  covenants,   restrictions,   conditions  or
          provisions an Event of Default  permitting  the  enforcement of all or
          any of the several  remedies  provided in this Indenture as herein set
          forth;  provided,  that in respect of any such addi  tional  covenant,
          restriction,  condition or provision such  supplemental  indenture may
          provide for a particu lar 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 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 to waive
          such an Event of Default;

                                      -40-



<PAGE>



               (d) 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  provision in
          regard to matters or questions  arising under this  Indenture or under
          any  supplemental  indenture  as  the  Board  of  Directors  may  deem
          necessary or desirable,  provided that no such action shall  adversely
          affect the interests of the Holders of the Securities;

               (e) to provide for  adjustment of conversion  rights  pursuant to
          Section 13.5; or

               (f) to evidence the removal or resignation of the Trustee and the
          appointment  of a successor  Trustee or  Trustees  pursuant to Article
          Five.

         The Trustee is hereby  authorized  to join 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  thereunder,  but the
Trustee  shall not be  obligated to enter into any such  supplemental  indenture
which  affects  adversely  the  Trustee's  own  rights,  duties,  immunities  or
liabilities under this Indenture or otherwise.

         Any supplemental indenture authorized by the provisions of this Section
7.1 may be executed  without the consent of the Holders of any of the Securities
at the time Outstanding, notwithstanding any of the provisions of Section 7.2.

         SECTION 7.2  Supplemental  Indentures with Consent of  Securityholders.
With the consent  (evidenced  as provided in Article  Six) of the Holders of not
less than a majority in aggregate principal amount of the Securities at the time
Outstanding  (or, prior to any exchange of Securities for Convertible  Preferred
Stock,  with  the  consent  of  holders  of  not  less  than a  majority  of the
Outstanding shares of Convertible  Preferred Stock), the Issuer, when authorized
by a resolution  of its Board of  Directors,  and the Trustee may,  from time to
time and at any time, enter into an indenture or indentures  supplemental hereto
for the  purpose  of adding  any  provisions  to or  changing  in any  manner or
eliminating  any of the  provisions  of this  Indenture  or of any  supplemental
indenture  or of  modifying  in any  manner  the  rights of the  Holders  of the
Securities;  provided,  that no such supplemental indenture shall (a) extend the
final

                                      -41-



<PAGE>



maturity of any Security,  or reduce the principal amount thereof or premium, if
any,  thereon,  or reduce the rate or extend  the time of  payment  of  interest
thereon, or any premium payable upon the redemption thereof, or change the place
of payment where,  or the coin or currency in which,  any principal,  premium or
interest is payable,  or reduce or alter the method of calculation of any amount
payable  on  redemption  or  repayment  thereof  (or the time at which  any such
redemption  may be  made),  or  impair  or  adversely  affect  the  right of any
Securityholder  to  institute  suit for the  payment  or  conversion  thereof or
adversely  affect the right to convert the Securities in accordance with Article
Thirteen,  in each case,  without the consent of the Holder of each  Security so
affected;  provided, no consent of any Holder of any Security shall be necessary
under  this  Section  7.2 to  permit  the  Trustee  and the  Issuer  to  execute
supplemental  indentures  pursuant to Section  7.1(e) and  Section  13.5 of this
Indenture;  or (b)  reduce  the  aforesaid  percentage  in  principal  amount of
Outstanding Securities,  the consent of the Holders of which is required for any
such supplemental indenture, without the consent of the Holders of each Security
so affected;  or (c) reduce the percentage of Securities necessary to consent to
waive any past default under this Indenture to less than a majority, without the
consent  of the  Holders  of  each  Security  so  affected,  or (d)  modify  the
provisions of Article Twelve hereof or any other  provision  hereof  relating to
subordination  of the  Securities in any manner  adverse to the  Securityholders
without the consent of the Holder of each  Security so  affected,  or (e) modify
any of the  provisions of this Section or Section  4.10,  except to increase any
such percentage provided in either such Section or to provide that certain other
provisions of this Indenture cannot be modified or waived without the consent of
the Holder of each Security affected thereby.

         Upon the request of the Issuer,  accompanied  by a copy of 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),
certified by the Secretary or an Assistant Secretary of the Issuer,  authorizing
the execution of any such supplemental  indenture,  and upon the filing with the
Trustee of evidence of the consent of  Securityholders  and other documents,  if
any,  required by Section  6.1,  the  Trustee  shall join with the Issuer in the
execution of such  supplemental  indenture  unless such  supplemental  indenture
adversely  affects the Trustee' own rights,  duties,  immunities or  liabilities
under this Indenture or otherwise,

                                      -42-



<PAGE>



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 Securityholders  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 Issuer
shall mail a notice thereof by first-class  mail to the Holders of Securities at
their  addresses  as they  shall  appear on the  registry  books of the  Issuer,
setting forth in general terms the substance of such supplemental indenture. Any
failure of the Issuer to mail such  notice,  or any defect  therein,  shall not,
however,  in any way  impair or affect  the  validity  of any such  supplemental
indenture.

         SECTION 7.3 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
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  deemed  to be part of the
terms and conditions of this Indenture for any and all purposes.

         SECTION 7.4 Documents to be Given to Trustee.  The Trustee,  subject to
the provisions of Sections 5.1 and 5.2, may receive an Officers' Certificate and
an  Opinion  of  Counsel  as  conclusive  evidence  that any  such  supplemental
indenture complies with the applicable provisions of this Indenture.

         SECTION  7.5  Notation  on  Securities   in  Respect  of   Supplemental
Indentures.  Securities  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 the Issuer or the Trustee shall so  determine,  new
Securities  so  modified  as to  conform,  in the opinion of the Trustee and the
Board of Directors,  to any modification of this Indenture contained in any such
supplemental indenture may

                                      -43-



<PAGE>



be prepared  by the  Issuer,  authenticated  by the  Trustee  and  delivered  in
exchange for the Securities then Outstanding.


                                  ARTICLE EIGHT

                    CONSOLIDATION, MERGER, SALE OR CONVEYANCE

         SECTION 8.1 Covenant Not to Merge, Consolidate, Sell or Convey Property
Except Under Certain Conditions.

         The Issuer may not  consolidate  or merge with or into  (whether or not
the Issuer is the Surviving Person), or sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its properties or assets in one
or more related transactions, to another Person (each a "Disposition"), unless:

         (i) the Surviving  Person is a corporation  organized or existing under
         the laws of the United  States,  any state  thereof or the  District of
         Columbia;

         (ii) the  Surviving  Person (if other than the Issuer)  assumes all the
         obligations of the Issuer under the Securities and this Indenture,  and
         makes provision for conversion  rights in accordance with Section 13.5,
         pursuant to a supplemental indenture in a form reasonably  satisfactory
         to the Trustee; and

         (iii) immediately after such Disposition,  no Event of Default or event
         that,  after the giving of notice or the passage of time or both, would
         be an Event of Default, shall have occurred and be continuing.

         SECTION 8.2 Successor Corporation or Entity Substituted. In case of any
such consolidation, merger, sale or conveyance, and following such an assumption
by the successor  corporation,  partnership or limited liability  company,  such
successor corporation, partnership or limited liability company shall succeed to
and be substituted for the Issuer,  with the same effect as if it had been named
herein.

         Such successor  corporation,  partnership or limited  liability company
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

                                      -44-



<PAGE>



of such successor corporation, partnership or limited liability company, 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 corporation, partnership or limited liability company 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  corporation,  partnership or limited
liability  company  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 8.3 Opinion of Counsel to Trustee. The Trustee,  subject to the
provisions  of Sections 5.1 and 5.2, may receive an Opinion of Counsel  prepared
in  accordance   with  Section  10.5  as  conclusive   evidence  that  any  such
consolidation,  merger, sale, lease or conveyance,  and any such assumption, and
any such liquidation or dissolution,  complies with the applicable provisions of
this Indenture.


                                  ARTICLE NINE

                           SATISFACTION AND DISCHARGE
                         OF INDENTURE; UNCLAIMED MONEYS


         SECTION 9.1 Satisfaction and Discharge of Indenture. If at any time (a)
the Issuer shall have paid or caused to be paid the principal of and premium, if
any, and interest on all the Securities then Outstanding hereunder,  as and when
the same  shall  have  become  due and  payable,  or (b) the  Issuer  shall have

authenticated (other

interest at such times and in such  amounts as will insure the  availability  of
cash,  or 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 the  principal of and
interest on all  Securities on each date that such  principal or interest is due
and payable;  and if, in any such case, the Issuer shall also pay or cause to be
paid all other sums payable  hereunder by the Issuer,  then this Indenture shall
cease to be of  further  effect  (except  as to (i)  rights of  registration  of
transfer,  conversion  and exchange of  Securities,  and the  Issuer's  right of
optional  redemption  contemplated in clause  (c)(i)(y) above (but not otherwise
and not  including  the Holders'  right of  redemption  contemplated  by Article
Fourteen), (ii) substitution of apparently mutilated,  defaced,  destroyed, lost
or stolen  Securities,  (iii)  rights of the  Holders of  Securities  to receive
payments of principal thereof and premium,  if any and interest thereon upon the
original stated due dates therefor (but not upon acceleration), (iv) the rights,
obli gations and  immunities  of the Trustee  hereunder,  including any right to
compensation  and  indemnification  under Section 5.5, and (v) the rights of the
Holders of  Securities as  beneficiaries  hereof with respect to the property so
deposited with the Trustee payable to all or any of them),  and the Trustee,  on
demand of the Issuer  accompanied by an Officers'  Certificate and an Opinion of
Counsel  stating that the provisions of this Section have been complied with and
at the  cost  and  expense  of the  Issuer,  shall  execute  proper  instruments
acknowledging  such  satisfaction of and discharging  this Indenture,  provided,
that the rights of Holders of the  Securities  to receive  amounts in respect of
principal of, premium, if any, and interest on the Securities held by them shall
not be delayed  longer  than  required  by  then-applicable  mandatory  rules or
policies of any securities  exchange upon which the  Securities  are listed.  In
addition, in connection with the satisfaction

                                      -46-



<PAGE>



and discharge  pursuant to clause (c)(i)(y) above, the Trustee shall give notice
to the Holders of  Securities of such  satisfaction  and  discharge.  The Issuer
agrees to reimburse the Trustee for any costs or expenses thereafter  reasonably
and properly incurred and to compensate the Trustee for any services  thereafter
reasonably  and  properly  rendered  by the  Trustee  in  connection  with  this
Indenture or the Securities.

         Notwithstanding  the satisfaction and discharge of this Indenture,  the
obligations of the Issuer to the Trustee under Section 5.5 shall survive.

         SECTION 9.2  Application  by Trustee of Funds  Deposited for Payment of
Securities. Subject to Section 9.4, all moneys and securities deposited with the
Trustee  pursuant to Section 9.1 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 the particular Securities for
the payment or redemption of which such moneys or Securities have been deposited
with the  Trustee of all sums due and to become due thereon  for  principal  and
interest;  but such moneys or securities need not be segregated from other funds
except to the extent required by law.

         SECTION 9.3  Repayment of Moneys Held by Paying  Agent.  In  connection
with  the   satisfaction  and  discharge  of  this  Indenture  with  respect  to
Securities,  all moneys then held by any Paying  Agent under the  provisions  of
this Indenture shall,  upon demand of the Issuer, be repaid to it or paid to the
Trustee  and  thereupon  such Paying  Agent  shall be released  from all further
liability with respect to such moneys.

         SECTION 9.4 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 premium, if any, or interest on any
Security and not applied but  remaining  unclaimed  for two years after the date
upon which such principal, premium 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 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

                                      -47-



<PAGE>



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,  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 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,  any  unclaimed  balance of such money then
remaining will be repaid to the Issuer.

         SECTION 9.5 Indemnity for U.S. Government Obligations. The Issuer shall
pay and indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the U.S. Government  Obligations  deposited pursuant to Section
9.1 or the principal or interest received in respect of such obligations.

Directors of Issue Exempt from Individual  Liability.  No recourse under or upon
any obliga tion,  covenant or agreement  contained in this Indenture,  or in any
Security, 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 partner or member 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  by  the  Holders  thereof  and  as  part  of the
consideration for the issue of the Securities.

         SECTION 10.2  Provisions  of Indenture  for the Sole Benefit of Parties

implied,  shall  give or be  construed  to give to any  Person,  other  than the
parties hereto and their  successors and the holders of Senior  Indebtedness and
the Holders of the  Securities,  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,  the holders of Senior Indebtedness and the Holders of the
Securities.

         SECTION 10.3  Successors and Assigns of Issuer Bound by Indenture.  All
the covenants, stipulations, promises and agreements in this Indenture contained
by or in behalf of the Issuer shall bind its successors and assigns,  whether so
expressed or not.

         SECTION   10.4   Notices   and   Demands   on   Issuer,   Trustee   and
Securityholders.  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 the Holders
of  Securities  to or on the  Issuer  may be given or served by being  deposited
postage  prepaid,  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 American Radio Systems Corporation,  116 Huntington Avenue,
Boston, MA 02116, Attention:  Chief Financial Officer and Secretary. Any notice,
direction,  request or demand by the Issuer or any Securityholder to or upon the
Trustee  shall be  deemed  to have  been  sufficiently  given  or made,  for all
purposes, if given or made at the Corporate Trust Office,  Attention:  Corporate
Trustee Administration Department.

         Where this Indenture provides for notice to Holders,  such notice shall
be sufficiently given (except as otherwise  specifically  provided herein) if in
writing,  and mailed,  first-class  postage  prepaid,  to each  Holder  entitled
thereto, at his last address as it appears in the Security register. In any case
where  notice to  Holders  is given by mail,  neither  the  failure to mail such
notice,  nor any defect in any notice so mailed,  to any particular Holder 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 irregu  larities in regular
mail  service,  it shall be  impracticable  to mail  notice  to the  Issuer  and
Securityholders  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
satisfactory  to the Trustee  shall be deemed to be a sufficient  giving of such
notice.

         SECTION 10.5 Officers' Certificates and Opinions of Counsel; Statements

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  represen  tations  by  counsel,  unless  such  officer  knows  that  the
certificate 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 counsel may be based,  insofar as it

the date of maturity of interest on or principal of the  Securities  or the date
fixed for redemp tion or  repayment  of any Security or the last date on which a
Holder  of  Securities  has a right to  convert  his  Securities  shall not be a
Business Day, then  (notwithstanding any other provision of this Indenture or of
the Securities) payment of interest or principal or conversion of the Securities
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 or on such last day for  conversion,  and
no interest shall accrue for the period after such date.

         list of  similar  form and  content  as of a date not more than 15 days
         prior to the time such list is furnished;

excluding from any such list names and addresses  received by the Trustee in the

         SECTION 10.8 New York Law to Govern.  This  Indenture and each Security

         SECTION 10.9 Counterparts. This Indenture may be executed in any number

together constitute but one and the same instrument.

         SECTION  10.10  Effect of  Headings.  The Article and Section  headings
herein and the Table of Contents are for  convenience  only and shall not affect

                            REDEMPTION OF SECURITIES

         SECTION 11.1 Right of Optional  Redemption;  Prices.  The Issuer at its
option  may,  at any time,  redeem  all,  or from time to time any part of,  the
Securities upon payment of the optional  Redemption Prices set forth in the form
of Security attached as Exhibit A hereto,  together with accrued interest to the
date fixed for redemption.

         SECTION  11.2  Notice of  Redemption;  Partial  Redemptions.  Notice of
redemption  to the  Holders of  Securities  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 of  Securities at their last  addresses as they shall
appear upon the registry books.  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 designated for redemption as a whole or
in part,  shall not affect the validity of the proceedings for the redemption of
any other Security.

         The  notice  of  redemption  to each  such  Holder  shall  specify  the
principal  amount of each Security held by such Holder to be redeemed,  the date
fixed for redemption (the "Redemption  Date"), the applicable  Redemption Price,
the place or places of payment,  that payment will be made upon presentation and
surrender  of such  Securities,  that  interest  accrued  to the date  fixed for
redemption  will be paid as  specified in said notice and that on and after said
date  interest  thereon or on the portions  thereof to be redeemed will cease to
accrue, and shall also specify the Conversion

                                      -52-



<PAGE>



Price then in effect and the date on which the right to convert such  Securities
or the portions  thereof to be redeemed will expire.  In case any Security is to
be redeemed in part only 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 in principal  amount equal to the unredeemed  portion thereof will be
issued.

         The notice of  redemption of Securities 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.

         At least one Business Day prior to 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 2.3) an amount of money suffi cient to redeem on the Redemption Date all
the  Securities  so  called  for  redemption   (other  than  those   theretofore
surrendered for conversion pursuant to Article 13) at the appropriate Redemption
Price,  together  with  accrued  interest  to and  including  the date fixed for
redemption.  If any Security called for redemption is converted pursuant hereto,
any money  deposited  with the Trustee or any Paying Agent or so segregated  and
held in trust for the  redemption of such  Security  shall be paid to the Issuer
upon the Issuer's request,  or, if then held by the Issuer,  shall be discharged
from  such  trust.  If less  than  all the  outstanding  Securi  ties  are to be
redeemed,  the Issuer will  deliver to the Trustee at least 10 days prior to the
date of making of the notice of redemption an Officers'  Certificate stating the
aggregate principal amount of Securities to be redeemed.

         If less than all the Securities  are to be redeemed,  the Trustee shall
select,  by lot, pro rata or by such other  manner as it shall deem  appropriate
and fair,  Securities  to be  redeemed  in whole or in part.  Securities  may be
redeemed in part in multiples equal to the minimum  authorized  denomination for
Securities or any multiple thereof. The Trustee shall promptly notify the Issuer
in writing of the  Securities  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 this  Indenture,  unless the  context  otherwise
requires,  all provisions relating to the redemption of Securities shall relate,
in the case of any  Security  redeemed  or to be redeemed  only in part,  to the
portion of

                                      -53-



<PAGE>



the principal  amount of such Security  which has been or is to be redeemed.  If
any Security selected for partial redemption is surrendered for conversion after
such selection,  the converted  portion of such Security shall be deemed (so far
as may be) to be the portion  selected for  redemption.  Upon any  redemption of
less than all the Securities,  for purposes of the selection for redemption, the
Issuer and the  Trustee  may treat as  Outstanding  Securities  surrendered  for
conversion  during the period of 15 days next  preceding the mailing of a notice
of redemption,  and need not treat as Outstanding any Security authenticated and
delivered  during  such period in exchange  for the  unconverted  portion of any
Security converted in part during such period.

         SECTION 11.3 Payment of Securities Called for Redemption.  If notice of
redemption  has been given as above  provided,  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 and including the date fixed for redemption, and on and
after  said date  (unless  the  Issuer  shall  default  in the  payment  of such
Securities at the 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 and such  Securities  shall cease from and after the close
of  business  on the  Business  Day  immediately  prior  to the date  fixed  for
redemption to be convertible pursuant to the provisions of Article 13 or, except
as  provided  in  Sections  2.4 and 9.4,  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 and including the date fixed for  redemption.  On
presentation and surrender of such Securities at a place of payment specified in
said notice, said 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 and  including  the date  fixed  for  redemption,
provided that any payment of interest becoming due on or prior to the date fixed
for redemption shall be payable to the Holders of such Securities  registered as
such on the relevant  record date subject to the terms and provisions of Section
2.11 hereof.

         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 specified in such Security and such Security shall remain

                                      -54-



<PAGE>



convertible pursuant to the provisions of Article 13 until the principal of such
Security shall have been paid or duly provided for.

         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  authorized  denominations,  in  principal  amount  equal to the
unredeemed portion of the Security so presented.

         SECTION  11.4  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 a written statement signed by an authorized  officer of the Issuer and
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 directly or indirectly  controlling or
controlled by or under direct or indirect common control with the Issuer.

                           SUBORDINATION OF SECURITIES

         SECTION 12.1 Securities Subordinate to Senior Indebtedness.  The Issuer
covenants and agrees, and each Holder of a Security,  by his acceptance thereof,
likewise covenants and agrees, that, to the extent and in the manner hereinafter
set forth in this  Article  (subject to the  provisions  of Article  Nine),  the
payment of the principal of (and  premium,  if any) and interest on each and all
of the Securities are hereby  expressly made subordinate and subject in right of
payment to the prior payment in full of all Senior Indebtedness.

         SECTION 12.2.  Payment Over of Proceeds Upon  Dissolution,  Etc. In the
event  of  (a)  any  insolvency  or  bankruptcy  case  or  proceeding,   or  any
receivership, liquidation, reorganization or other similar case or proceeding in
connection therewith, relative to the Issuer or to its creditors, as such, or to
its  assets,  or (b) any  liquidation,  dissolution  or other  winding up of the
Issuer,  whether  voluntary  or  involuntary  and  whether  or  not  involv  ing
insolvency or bankruptcy,  or (c) any assignment for the benefit of creditors or
any other marshalling of assets or

                                      -55-



<PAGE>



liabilities of the Issuer,  then and in any such event  specified in (a), (b) or
(c)  above  (each  such  event,  if  any,  herein  sometimes  referred  to  as a
"Proceeding")  the  holders of Senior  Indebtedness  will be first  entitled  to
receive  payment in full of all amounts due or to become due on or in respect of
all Senior Indebtedness, or provision shall be made for such payment, in cash or
Cash Equivalents or otherwise in a manner  satisfactory to the holders of Senior
Indebtedness,  before the Holders of the  Securities are entitled to receive any
payment or distribution of any kind or character, on account of principal of (or
premium,  if  any)  or  interest  on or  other  obligations  in  respect  of the
Securities  or on  account  of  any  purchase,  redemption  (including,  without
limitation, any redemption pursuant to Article Fourteen) or other acquisition of
Securities  by the Issuer or any  Subsidiary  of the Issuer (all such  payments,
distributions,  purchases,  redemptions  and  acquisitions  herein  referred to,
individually and collectively,  as a "Securities Payment"),  and to that end the
holders of Senior Indebtedness shall be entitled to receive,  for application to
the payment thereof,  any Securities Payment which may be payable or deliverable
in respect of the Securities in any such Proceeding.

         In the event that,  notwithstanding  the  foregoing  provisions of this
Section, the Trustee receives payment or distribution of assets of the Issuer of
any kind or  character,  before all the Senior  Indebtedness  is paid in full in
cash or Cash Equivalents,  then and in such event such Securities  Payment shall
be paid over or  delivered  forthwith  to the trustee in  bankruptcy,  receiver,
liquidating trustee,  custodian,  assignee, agent or other Person making payment
or  distribution  of assets of the Issuer for  application to the payment of all
Senior Indebtedness  remaining unpaid, to the extent necessary to pay the Senior
Indebtedness in full in cash or Cash Equivalents.

         For  purposes  of  this  Article  only,   the  words  "any  payment  or
distribution of any kind or character,  whether in cash, property or securities"
shall not be deemed to include a payment or  distribution of stock or securities
of the  Issuer  provided  for by a  plan  of  reorganization  or  readjust  ment
authorized  by an order or  decree  of a court of  competent  jurisdiction  in a
reorganization  proceeding  under any applicable  bankruptcy law or of any other
corporation  provided for by such plan of reorganization  or readjustment  which
stock or securities are subordinated in right of payment to all then outstanding
Senior  Indebtedness  to at  least  the same  extent  as the  Securities  are so
subordinated as provided in this Article; provided that (1) if a new

                                      -56-



<PAGE>



corporation results from such  reorganization or readjustment,  such corporation
assumes any Senior  Indebtedness not paid in full in cash or Cash Equivalents in
connection with such  reorganization  or readjustment  and (2) the rights of the
holders  of such  Senior  Indebtedness  are not,  without  the  consent  of such
holders,  altered by such  reorganization or readjustment.  The consolidation of
the  Issuer  with,  or the  merger of the  Issuer  into,  another  Person or the
liquidation or dissolution of the Issuer following the conveyance or transfer of
all or substantially  all of its properties and assets as an entirety to another
Person  upon the terms and  conditions  set forth in Article  Eight shall not be
deemed a Proceeding  for the  purposes of this  Section if the Person  formed by
such  consolidation  or into  which the  Issuer is  merged or the  Person  which
acquires by conveyance or transfer such properties and assets as an entirety, as
the case may be, shall, as a part of such consolidation,  merger,  conveyance or
transfer, comply with the conditions set forth in Article Eight.

         SECTION  12.3  Payments  to  Securityholders.  No payment on account of
principal  of or premium or interest on the  Securities  shall be made if at the
time of such payment or immediately  after giving effect thereto (1) there shall
exist a default in any payment  with respect to any Senior  Indebtedness  or (2)
there shall have occurred a default (as defined in such Senior  Indebtedness  or
in the instrument  under which the same is outstanding,  other than a default in
the  payment of amounts due  thereon)  with  respect to any Senior  Indebtedness
permitting the holders thereof, whether with notice, upon the passage of time or
both, to accelerate the maturity  thereof,  and such default shall not have been
cured or waived or shall not have ceased to exist.

         In the event that,  notwithstanding  the  foregoing,  the Company shall
make any  Securities  Payment to the  Trustee or any  Holder  prohibited  by the
foregoing provisions of this Section, then and in such event, subject to Section
12.4, such payment shall be paid over and delivered  forthwith to the holders of
the Senior Indebtedness remaining unpaid, or any trustee therefor, to the extent
necessary  to  pay  in  full  in  cash  and  Cash  Equivalents  all  the  Senior
Indebtedness.

         The  provisions  of this  Section  shall not apply to any payment  with
respect to which Section 12.2 would be applicable.

         SECTION 12.4 Payment Permitted If No Default. Nothing contained in this
Article or elsewhere in this Indenture or in any of the Securities shall prevent
(a) the Issuer, at any time except during the pendency of any

                                      -57-



<PAGE>



Proceeding  referred to in Section  12.2 or under the  conditions  described  in
Section 12.3,  from making  Securities  Payments,  or (b) the application by the
Trustee of any money  deposited with it hereunder to Securities  Payments or the
retention of such  Securities  Payment by the  Holders,  if, at the time of such
application  by the  Trustee,  it did not have  knowledge  that such  Securities
Payment would have been prohibited by the provisions of this Article.


         SECTION 12.5  Subrogation to Rights of Holders of Senior  Indebtedness.
Subject  to the  payment  in full of all  amounts  due or to become due on or in
respect of Senior  Indebtedness,  or the provision for such payment,  in cash or
Cash Equivalents or otherwise in a manner  satisfactory to the holders of Senior
Indebtedness,  the Holders of the  Securities  shall be subrogated  (equally and
ratably with the holders of all  Indebtedness of the Issuer which by its express
terms is subordinated to  Indebtedness of the Issuer to  substantially  the same
extent as the  Securities are  subordinated  to the Senior  Indebtedness  and is
entitled  to  like  rights  of   subrogation   by  reason  of  any  payments  or
distributions made to holders of such Senior  Indebtedness) to the rights of the
holders of such Senior  Indebtedness to receive  payments and  distributions  of
cash,  property and securities  applicable to the Senior  Indebtedness until the
principal of (and premium,  if any) and interest on the Securities shall be paid
in full. For purposes of such  subrogation,  no payments or distributions to the
holders of the Senior  Indebtedness of any cash, property or securities to which
the Holders of the  Securities or the Trustee  would be entitled  except for the
provisions of this Article,  and no payments over pursuant to the  provisions of
this Article to the holders of Senior  Indebtedness by Holders of the Securities
or the Trustee,  shall, as among the Issuer, its creditors other than holders of
Senior Indebtedness and the Holders of the Securities, be deemed to be a payment
or distribution by the Issuer to or on account of the Senior Indebtedness.

         SECTION  12.6  Provisions   Solely  to  Define  Relative  Rights.   The
provisions  of this  Article  are and are  intended  solely  for the  purpose of
defining the  relative  rights of the Holders on the one hand and the holders of
Senior  Indebtedness  on the other hand.  Nothing  contained  in this Article or
elsewhere  in this  Indenture or in the  Securities  is intended to or shall (a)
impair,  as among  the  Issuer,  its  creditors  other  than  holders  of Senior
Indebtedness  and the Holders of the  Securities,  the obligation of the Issuer,
which is absolute and unconditional, to pay to the Holders of the Securities the
principal of (and premium, if any) and

                                      -58-



<PAGE>



interest on the  Securities as and when the same shall become due and payable in
accordance  with their  terms;  or (b) affect the  relative  rights  against the
Issuer of the Holders of the  Securities  and creditors of the Issuer other than
the holders of Senior Indebtedness;  or (c) prevent the Trustee or the Holder of
any Security from exercising all remedies otherwise  permitted by applicable law
upon default under this  Indenture,  subject to the rights,  if any,  under this
Article of the holders of Senior  Indebtedness  to receive  cash,  property  and
securities otherwise payable or deliverable to the Trustee or such Holder.

         SECTION  12.7  Trustee to  Effectuate  Subordination.  Each Holder of a
Security by his  acceptance  thereof  authorizes  and directs the Trustee on his
behalf to take such action as may be necessary or  appropriate to effectuate the
subordination   provided  in  this   Article  and   appoints   the  Trustee  his
attorney-in-fact for any and all such purposes.

         SECTION 12.8. No Waiver of  Subordination  Provisions.  No right of any
present or future holder of any Senior Indebtedness to enforce  subordination as
herein  provided  shall at any time in any way be  prejudiced or impaired by any
act or failure to act on the part of the Issuer or by any act or failure to act,
in good faith, by any such holder,  or by any  noncompliance  by the Issuer with
the  terms,  provisions  and  covenants  of this  Indenture,  regardless  of any
knowledge thereof any such holder may have or be otherwise charged with.

         Without in any way limiting the generality of the foregoing  paragraph,
the  holders  of  Senior  Indebtedness  may,  at any time and from time to time,
without  the  consent  of or  notice  to  the  Trustee  or  the  Holders  of the
Securities,  without  incurring  responsibility to the Holders of the Securities
and without  impairing or releasing the subordina  tion provided in this Article
or the obligations  hereunder of the Holders of the Securities to the holders of
Senior Indebtedness, do any one or more of the following: (i) change the manner,
place or terms of payment or extend the time of payment  of, or renew,  increase
or alter,  Senior  Indebtedness,  or otherwise amend or supplement in any manner
Senior Indebtedness or any instrument evidencing the same or any agreement under
which Senior  Indebtedness  is outstand  ing;  (ii) sell,  exchange,  release or
otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness;  (iii)  release any Person liable in any manner for the payment or
collection of Senior Indebtedness;  and (iv) exercise or refrain from exercising
any rights against the Issuer and any other Person.

         SECTION 12.9.  Notice to Trustee.  The Issuer shall give prompt written
notice to the Trustee of any fact known to the Issuer  which would  prohibit the
making  of any  payment  to or by the  Trustee  in  respect  of the  Securities.
Notwithstanding  the  provisions of this Article or any other  provision of this
Indenture,  the Trustee shall not be charged with  knowledge of the existence of
any facts which would prohibit the making of any payment to or by the Trustee in
respect of the  Securities,  unless and until the  Trustee  shall have  received
written  notice  thereof from the Issuer or a holder of Senior  Indebtedness  or
from any trustee therefor; and, prior to the receipt of any such written notice,
the Trustee,  subject to the provisions of Section 5.1, shall be entitled in all
respects  to assume that no such facts  exist;  provided,  however,  that if the
Trustee shall not have received the notice provided for in this Section at least
three  Business  Days prior to the date upon which by the terms hereof any money
may become payable for any purpose (including,  without limitation,  the payment
of the principal of (and premium,  if any) or interest on any  Security),  then,
anything  herein  contained to the contrary  notwithstanding,  the Trustee shall
have full power and authority to receive such money and to apply the same to the
purpose  for which  such money was  received  and shall not be  affected  by any
notice to the contrary  which may be received by it within three  Business  Days
prior to such date.

         Subject to the  provisions  of Article 5, the Trustee shall be entitled
to rely on the  delivery  to it of a  written  notice  by a Person  representing
himself  to be a holder  of  Senior  Indebtedness  (or a  trustee  therefor)  to
establish that such notice has been given by a holder of Senior Indebtedness (or
a trustee therefor). In the event that the Trustee determines in good faith that
further evidence is required with respect to the right of any Person as a holder
of Senior Indebtedness to participate in any payment or distribution pursuant to
this  Article,  the Trustee may request  such Person to furnish  evidence to the
reasonable  satisfaction of the Trustee as to the amount of Senior  Indebtedness
held by such Person,  the extent to which such Person is entitled to participate
in such payment or  distribution  and any other facts pertinent to the rights of
such Person  under this  Article,  and if such  evidence is not  furnished,  the
Trustee may defer any payment to such Person pending  judicial  determination as
to the right of such Person to receive such payment.

         SECTION 12.10. Reliance on Judicial Order or Certificate of Liquidating
Agent.  Upon any payment or  distribution of assets of the Issuer referred to in
this  Article,  the  Trustee,  subject to the  provisions  of Article 5, and the
Holders of the  Securities  shall be  entitled  to rely upon any order or decree
entered  by any court of  competent  jurisdiction  in which such  Proceeding  is
pending,  or a certificate of the trustee in bankruptcy,  receiver,  liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other Person
making such payment or distribution,  delivered to the Trustee or to the Holders
of  Securities,  for  the  purpose  of  ascertaining  the  Persons  entitled  to
participate  in  such  payment  or  distribution,  the  holders  of  the  Senior
Indebtedness and other indebtedness of the Issuer, the amount thereof or payable
thereon,  the amount or amounts paid or distributed  thereon and all other facts
pertinent thereto or to this Article.

         SECTION   12.11.   Trustee   Not   Fiduciary   for  Holders  of  Senior
Indebtedness.  The Trustee shall not be deemed to owe any fiduciary  duty to the
holders of Senior Indebtedness and shall not be liable to any such holders if it
shall in good faith  mistakenly  pay over or distribute to Holders of Securities
or to the Issuer or to any other Person cash,  property or  securities  to which
any holders of Senior  Indebtedness  shall be entitled by virtue of this Article
or otherwise.

         SECTION  12.12.  Rights of  Trustee  as Holder of Senior  Indebtedness;
Preservation of Trustee's Rights.  The Trustee in its individual  capacity shall
be  entitled  to all the rights set forth in this  Article  with  respect to any
Senior  Indebtedness  which may at any time be held by it, to the same extent as
any other holder of Senior  Indebtedness,  and nothing in this  Indenture  shall
deprive the Trustee of any of its rights as such holder.

         Nothing in this  Article  shall apply to claims of, or payments to, the
Trustee under or pursuant to Article 5.

         SECTION 12.13. Article Applicable to Paying Agents. In case at any time
any Paying Agent other than the Trustee shall have been  appointed by the Issuer
and be then acting  hereunder,  the term "Trustee" as used in this Article shall
in such case (unless the context  otherwise  requires) be construed as extending
to and  including  such Paying Agent within its meaning as fully for all intents
and  purposes as if such Paying  Agent were named in this Article in addition to
or in place of the Trustee;  provided,  however,  that  Section  12.12 shall not
apply to the Issuer or any Affiliate of the Issuer if it or such  Affiliate acts
as Paying Agent.

         SECTION 12.14.  Securities Not Superior to Senior  Subordinated  Notes.
The  Securities  shall not be superior in right of payment to, and shall be on a
parity with or subordinated to (depending on the issuer's election in accordance
with the  definition  of Senior  Indebtedness  herein),  the  Issuer's 9% Senior
Subordinated Notes due 2006 issued pursuant to the Senior Note Indenture and all
amounts payable pursuant to such Notes and the Senior Note Indenture.

                                ARTICLE THIRTEEN

                            CONVERSION OF SECURITIES

         SECTION 13.1 Conversion  Privilege.  A Holder of a Security may convert
it into Class A Common  Stock of the Issuer at any time prior to maturity at the
conversion  price then in effect,  except  that,  with  respect to any  Security
called for  redemption,  such  conversion  right shall terminate at the close of
business on the  Business  Day  immediately  preceding  the  Redemption  Date or
Repurchase  Date  (unless  the Issuer  shall  default  in making the  redemption
payment then due, in which case the conversion right shall terminate on the date
such default is cured and, if applicable,  the provisions of Section 14.2(d) are
satisfied).  The  number  of  shares  of  Class A  Common  Stock  issuable  upon
conversion of a Security is determined as follows:  divide the principal  amount
to be converted by the Conversion  Price in effect on the Conversion Date; round
the result to the nearest 1/100th of a share.

         The initial Conversion Price is stated in paragraph 5 of the reverse of
the Securities and is subject to adjustment as provided in this Article Thirteen
(which initial  Conversion  Price shall be equal to the conversion  price of the
Convertible Preferred Stock in effect on the Exchange Date).

         A Holder may  convert a portion  of a  Security  equal to $1,000 or any
integral multiple thereof. Provisions of this Indenture that apply to conversion
of all of a Security also apply to conversion of a portion of it.

         SECTION 13.2 Exercise of Conversion Privilege. In order to exercise the
conversion privilege, the Holder of any Security to be converted shall surrender
such  Security  to the Issuer at any time  during  usual  business  hours at its
office or agency  maintained  for the  purpose as  provided  in this  Indenture,
accompanied by a fully executed written notice,  in  substantially  the form set
forth on the reverse of the Security, that the Holder elects to convert such

                                      -62-



<PAGE>



Security  or a stated  portion  thereof  constituting  a multiple of the minimum
authorized  denomination  thereof,  and,  if such  Security is  surrendered  for
conversion  during the period  between  the close of business on any record date
for such  Security and the opening of business on the related  interest  payment
date (unless such Security shall have been called for redemption on a Redemption
Date or Repurchase  Date within such period or on such interest  payment  date),
accom panied also by payment of an amount equal to the interest  payable on such
interest  payment  date on the portion of the  principal  amount of the Security
being surrendered for conversion.  A Holder of any Security on a record date for
such Security who converts such  Security on the related  interest  payment date
will receive the interest payable on such Security,  and such converting  Holder
need not include a payment for any such interest upon surrender of such Security
for conversion. Such notice shall also state the name or names (with address) in
which the certificate or  certificates  for shares of Class A Common Stock shall
be issued.  Securities  surrendered for conversion  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.
As promptly as practicable after the receipt of such notice and the surrender of
such  Security as  aforesaid,  the Issuer  shall,  subject to the  provisions of
Section 13.7,  issue and deliver at such office or agency to such Holder,  or on
his written order, a certificate or  certificates  for the number of full shares
of Class A Common Stock issuable on such  conversion of Securities in accordance
with the  provisions  of this Article and cash,  as provided in Section 13.3, in
respect of any  fraction of a share of Class A Common Stock  otherwise  issuable
upon such  conversion.  Such  conversion  shall be deemed to have been  effected
immediately  prior to the close of business on the date (herein called the "Date
of  Conversion") on which such notice shall have been received by the Issuer and
such  Security  shall  have been  surrendered  as  aforesaid,  and the Person or
Persons in whose name or names any  certificate  or  certificates  for shares of
Class A Common Stock shall be issuable upon such  conversion  shall be deemed to
have  become on the Date of  Conversion  the  holder or holders of record of the
shares represented thereby;  provided,  however,  that any such surrender on any
date  when  the  stock  transfer  books of the  Issuer  shall  be  closed  shall
constitute  the  person or persons  in whose  name or names the  certificate  or
certificates  for such  shares are to be issued as the  recordholder  or holders
thereof for all purposes at the opening of business on the next  succeeding  day
on which such stock transfer books are open but such conversion shall

                                      -63-



<PAGE>



nevertheless  be at the  Conversion  Price in effect at the close of business on
the date when such Security shall have been so  surrendered  with the conversion
notice.  In the case of  conversion  of a  portion,  but  less  than  all,  of a
Security,  the Issuer shall  execute,  and the Trustee  shall  authenticate  and
deliver to the Holder  thereof,  at the  expense of the  Issuer,  a Security  or
Securities in the aggregate  principal amount of the unconverted  portion of the
Security surrendered.  Except as otherwise expressly provided in this Indenture,
no payment or adjustment  shall be made for interest accrued on any Security (or
portion  thereof)  converted or for  dividends or  distributions  on any Class A
Common Stock issued upon conversion of any Security;  provided, however, that in
the case of any Securities  which are converted after the close of business on a
relevant  record date and on or prior to the next  succeeding  interest  payment
date,  installments of interest which are due and payable on the next succeeding
interest   payment  date  shall  be  payable  on  such  interest   payment  date
notwithstanding such conversion (unless such Security shall have been called for
redemption on a Redemption  Date or Repurchase  Date after the close of business
on such  record  date and prior to the  opening  of  business  on such  interest
payment date) and such interest (whether or not punctually paid or duly provided
for) shall be paid to the Holder of such  Securities  registered  as such at the
close of business on the relevant record date according to their terms.

         SECTION 13.3 Fractional  Shares.  Except as pro vided below, the Issuer
will not issue  fractional  shares of Class A Common  Stock upon  conversion  of
Securities.  In lieu thereof,  in the sole discretion of the Board of Directors,
either (a) such  fractional  interest  will be rounded  up to the  nearest  full
share, or (b) an appropriate  amount will be paid in cash by the Issuer,  unless
payment in cash is  prohibited  by the terms of the  Issuer's  Indebtedness,  in
which case  fractional  shares may be issued.  If the Issuer shall deliver cash,
such cash shall be in the amount of the fair market value (as  determined by the
Board of Directors) of such fractional interest. If more than one Security shall
be surrendered for conversion at one time by the same Holder, the number of full
shares  issuable upon  conversion  thereof shall be computed on the basis of the
aggregate  number  of  Securities,  or  the  specified  portions  thereof  to be
converted, so surrendered.

         SECTION 13.4 Adjustment of Conversion Price. The Conversion Price shall
be subject to adjustment from time to time as follows:


                                      -64-



<PAGE>



                  (a) In case the  Issuer  shall  (1) pay a  dividend  or make a
         distribution on Class A Common Stock in shares of Class A Common Stock,
         (2)  subdivide  its  outstanding  shares of Class A Common Stock into a
         greater number of shares or (3) combine its outstanding shares of Class
         A Common Stock into a smaller number of shares, the Conversion Price in
         effect  immediately  prior to such action shall be adjusted as provided
         below so that the Holder of any  Security  thereafter  surrendered  for
         conversion shall be entitled to receive the number of shares of Class A
         Common Stock which he would have been  entitled to receive  immediately
         following  such action had such  Security  been  converted  immediately
         prior thereto. An adjustment made pursuant to this subsection (a) shall
         become  effective  immedi ately,  except as provided in subsection  (e)
         below,  after the record date in the case of a dividend or distribution
         and shall become effective  immediately after the effective date in the
         case of a subdivision or combination.

                  (b) In case the Issuer shall issue rights, warrants or options
         to all  holders  of Class A Common  Stock  entitling  them for a period
         expiring within 45 days after the record date therefor to subscribe for
         or  purchase  shares of Class A Common  Stock at a price per share less
         than the  current  market  price per share (as  determined  pursuant to
         subsection  (d) below) of the Class A Common  Stock on the record  date
         mentioned  below,  the  Conversion  Price shall be adjusted to a price,
         computed  to the nearest  cent,  so that the same shall equal the price
         determined by multiplying:

                           (1)      the Conversion Price in effect
                  immediately prior to the date of issuance of such
                  rights, warrants or option by a fraction, of which

                           (2) the  numerator  shall be (A) the number of shares
                  of Class A Common Stock outstanding on the date of issuance of
                  such  rights,  warrants or options  immediately  prior to such
                  issuance,  plus (B) the number of shares  which the  aggregate
                  offering  price of the total  number of shares so offered  for
                  subscription or purchase would purchase at such current market
                  price  (determined by multiplying  such total number of shares
                  by the exercise price of such rights,  warrants or options and
                  dividing  the  product  so  obtained  by such  current  market
                  price), and of which


                                      -65-



<PAGE>



                           (3) the denominator shall be (A) the number of shares
                  of Class A Common Stock outstanding on the date of issuance of
                  such rights,  warrants or options,  immediately  prior to such
                  issuance,  plus (B) the number of additional shares of Class A
                  Common  Stock  which  are  so  offered  for   subscription  or
                  purchase.

                  Such adjustment shall become effective immedi ately, except as
         provided  in  subsection  (e)  below,  after  the  record  date for the
         determination of Holders  entitled to receive such rights,  warrants or
         options.

               (c) In case the Issuer shall distribute to all holders of Class A
          Common Stock evidences of Indebtedness,  equity securities  (including
          equity  interests  in the  Issuer's  Subsidiaries)  other than Class A
          Common Stock or other  assets  (other than cash  dividends),  or shall
          distribute to all holders of Class A Common Stock rights,  warrants or
          options to subscribe to  securities  (other than those  referred to in
          subsection  (b) above and  dividends and  distributions  in connection
          with the liquidation,  dissolution or winding up of the Issuer),  then
          in each such case the  Conversion  Price shall be adjusted so that the
          same shall equal the price  determined by  multiplying  the Conversion
          Price in effect  immediately prior to the date of such distribution by
          a fraction of which the  numerator  shall be the current  market price
          per share  (determined  as  provided in  subsection  (d) below) of the
          Class A Common Stock on the record date mentioned  below less the then
          fair market  value (as  determined  by the Board of  Directors,  whose
          determination  shall be conclusive evidence of such fair market value,
          and  described  in a Board  Resolution  filed with the Trustee) of the
          portion of the assets, evidences of Indebtedness and equity securities
          so distributed  or of such  subscription  rights,  warrants or options
          applicable  to one  share of Class A Common  Stock,  and of which  the
          denominator  shall be such current market price per share of the Class
          A Common Stock.  For the purposes of this subsection (c), in the event
          of a  distribution  of shares of capital stock or other  securities of
          any  Subsidiary as a dividend on shares of Class A Common  Stock,  the
          then  fair  market  value  of  the  shares  of  other   securities  so
          distributed  shall be deemed to be the  market  value  (determined  as
          provided  above) of such shares or other  securities.  Such adjustment
          shall become effective  immediately,  except as provided in subsection
          (e) below, after the record date for the determination of stockholders
          entitled to receive such distribution.

                  (d) For the purpose of any computation  under  subsections (b)
         and (c) above,  the  current  market  price per share of Class A Common
         Stock on any date  shall be deemed to be the  average  of the Last Sale
         Prices  of a share  of Class A Common  Stock  for the five  consecutive
         Trading  Days  commencing  not more than 20 Trading  Days  before,  and
         ending not later than, the earlier of the date in question and the date
         before  the "ex" date with  respect  to the  issuance  or  distribution
         requiring such  computation.  For purposes of this paragraph,  the term
         "'ex' date",  when used with  respect to any issuance or  distribution,
         means the first date on which the Class A Common Stock  trades  regular
         way on the principal national  securities exchange on which the Class A
         Common  Stock is listed or  admitted to trading (or if not so listed or
         admitted  on NASDAQ or a  similar  organization  if NASDAQ is no longer
         reporting  trading  information)  without  the  right to  receive  such
         issuance or distribution.

                  (e) In any case in which this  Section  shall  require that an
         adjustment be made immediately follow ing a record date, the Issuer may
         elect to defer the  effectiveness  of such  adjustment (but in no event
         until a date later than the effective  time of the event giving rise to
         such  adjustment),  in which case the Issuer shall, with respect to any
         Security  converted  after such record date and before such  adjustment
         shall have become  effective (i) defer making any cash payment pursuant
         to Section 13.3 or issuing to the Holder of such Security the number of
         shares of Class A Common  Stock and other  capital  stock of the Issuer
         issuable  upon such  conversion  in  excess of the  number of shares of
         Class A Common  Stock and other  capital  stock of the Issuer  issuable
         thereupon  only  on  the  basis  of  the  Conversion   Price  prior  to
         adjustment,  and (ii) not later  than five  Business  Days  after  such
         adjustment  shall  have  become  effective,  pay  to  such  Holder  the
         appropriate  cash  payment  pursuant to Section  13.3 and issue to such
         Holder the additional  shares of Class A Common Stock and other capital
         stock of the Issuer issuable on such conversion.

                  (f) No adjustment in the Conversion Price shall be required if
         Securityholders  are to participate  in the  transaction on a basis and
         with  notice  that the  Board of  Directors  determines  to be fair and
         appropri ate in light of the basis and notice on which holders

                                      -67-



<PAGE>



         of Class A Common Stock participate in the transaction. In addition, no
         adjustment  in the  Conversion  Price  shall be  required  unless  such
         adjustment  would require an increase or decrease of at least 1% in the
         Conversion  Price;  provided,  that any adjustments  which by reason of
         this  subsection  (f) are not  required  to be made  shall  be  carried
         forward  and taken  into  account  in any  subsequent  adjustment.  All
         calculations under this Article shall be made to the nearest cent or to
         the nearest one-hundredth of a share, as the case may be.

                  (g)  Whenever  the  Conversion  Price is  adjusted  as  herein
         provided,  the Issuer shall promptly (i) file with the Trustee and each
         conversion agent an Officers'  Certificate setting forth the Conversion
         Price after such adjustment and setting forth in reasonable  detail the
         facts  requiring  such  adjustment  and the  calculations  on which the
         adjustment is based, which certificate shall be conclusive  evidence of
         the correctness of such adjustment and which shall be made available by
         the Trustee to the Holders of Securities for inspection  thereof,  (ii)
         mail or cause to be mailed a notice of such  adjustment,  setting forth
         the  adjusted  Conversion  Price and the date on which such  adjustment
         became  or  becomes  effective,  to each  Holder of  Securities  at his
         address as the same appears on the registry books of the Issuer.

         To the extent permitted by law, the Issuer from time to time may reduce
the  Conversion  Price by any amount for any period of at least 20 days,  if the
Board of Directors has made a determination  that such reduction would be in the
best interests of the Issuer,  which determination shall be conclusive.  In such
case,  the  Issuer  shall  give at least 15 days'  notice of the  reduction.  In
addition,  at its option,  the Issuer may make such  reduction in the Conversion
Price as the Board of Directors  deems advisable to avoid or diminish any income
tax to  holders  of  Class  A  Common  Stock  resulting  from  any  dividend  or
distribution  of stock (or rights to acquire stock) or from any event treated as
such for income tax purposes.

         SECTION  13.5   Continuation   of  Conversion   Privilege  in  Case  of
Reclassification,  Reorganization,  Change,  Merger,  Consolidation  or  Sale of
Assets.  If any transaction shall occur,  including  without  limitation (i) any
recapitalization  or  reclassification  of shares of Class A Common Stock (other
than a change in par value,  or from par value to no par  value,  or from no par
value to par value,  or as a result of a subdivision or combination of the Class
A Common Stock), (ii) any consolidation or merger of the Issuer with or into

                                      -68-



<PAGE>



another  person or any merger of another  person  into the Issuer  (other than a
consolidation or merger that does not result in a reclassification,  conversion,
exchange or cancellation of Class A Common Stock), (iii) any sale or transfer of
all or  substantially  all of the assets of the Issuer,  or (iv) any  compulsory
share  exchange,  pursuant to any of which holders of Class A Common Stock shall
be  entitled  to  receive  other  securities,   cash  or  other  property,  then
appropriate  provision  shall be made so that the Holder of each  Security  then
Outstanding  shall have the right  thereafter to convert such Security only into
the kind and amount of the  securities,  cash or other  property that would have
been receivable  upon such  recapitalization,  reclassification,  consolidation,
merger,  sale, transfer or share exchange by a holder of the number of shares of
Class A Common Stock issuable upon conversion of such Security immediately prior
to  such  recapitalization,   reclassification,   consolidation,  merger,  sale,
transfer  or share  exchange,  after  giving  effect  to any  adjustment  in the
conversion price in accordance with Article Fourteen hereof.  The company formed
by such consolidation or resulting from such merger or that acquires such assets
or that acquires the Issuer's shares,  as the case may be, shall make provisions
in its certificate of incorporation or other  constituent  document to establish
such right.  Such  certificate of incorporation  or other  constituent  document
shall provide for adjustments  that, for events subsequent to the effective date
of such certificate of incorporation or other constituent documents, shall be as
nearly equivalent as may be practicable to the relevant adjustments provided for
in Section 13.4 and in this Section.

         SECTION 13.6 Notice of Certain Events. In case:

                  (a)  the  issuer  shall  declare  a  dividend  (or  any  other
         distribution)  payable to the  holders of Class A Common  Stock  (other
         than cash dividends and dividends payable in Class A Common Stock); or

                  (b) the Issuer shall  authorize the granting to the holders of
         Class A Common Stock of rights, warrants or options to subscribe for or
         purchase  any  shares  of stock of any  class or of any  other  rights,
         warrants or options; or

                  (c) the Issuer shall authorize any reclassifica tion or change
         of the Class A Common Stock (other than a subdivision or combination of
         its  outstanding  shares  of  Class A Common  Stock or a change  in par
         value,  or from par value to no par value,  or from no par value to par
         value), or any consolidation or merger to which the

                                      -69-



<PAGE>



         Issuer is a party and for which  approval  of any stock  holders of the
         Issuer is required,  or the sale or conveyance of all or  substantially
         all the property or business of the Issuer; or

               (d)  there  shall  be  proposed  any  voluntary  or   involuntary
          dissolution, liquidation or winding-up of the Issuer:

then,  the Issuer shall cause to be filed with the  Trustee,  and, if other than
the Corporate  Trust Office of the Trustee,  at the office or agency  maintained
for the purpose of conversion of the  Securities as provided in Section 2.3, and
shall  cause to be mailed to each  Holder of  Securities,  at his  address as it
shall appear on the registry books of the Issuer, as promptly as possible but in
any event at least 20 days before the date hereinafter specified (or the earlier
of the dates  hereinafter  specified,  in the  event  that more than one date is
specified),  a notice  stating  the date on which (1) a record is expected to be
taken for the  purpose  of such  dividend,  distribution,  rights,  warrants  or
options,  or if a record is not to be taken, the date as of which the holders of
Class A Common  Stock of record to be entitled to such  dividend,  distribution,
rights or warrants are to be determined,  or (2) such reclassification,  change,
consolidation,  merger, sale, transfer, conveyance, dissolution,  liquidation or
winding-up is expected to become  effective and the date, if any is to be fixed,
as of which it is expected  that holders of Class A Common Stock of record shall
be entitled to exchange  their shares of Class A Common Stock for  securities or
other property deliverable upon such  reclassification,  change,  consolidation,
merger, sale, transfer, conveyance, dissolution, liquidation or winding-up.

         SECTION  13.7  Taxes  on  Conversion.  The  issuance  and  delivery  of
certificates  for shares of Class A Common  Stock on  conversion  of  Securities
shall be made without  charge to the  converting  Holder of Securities  for such
certificates  or for any  documentary,  stamp or  similar  taxes  payable to the
United  States of  America  or any  political  subdivision  or taxing  authority
thereof in respect of the issuance or delivery of such  certificates;  provided,
however,  that the  Issuer  shall  not be  required  to pay any tax which may be
payable in respect of any transfer  involved in the issuance of certificates for
shares of Class A Common  Stock,  and no such  issue or  delivery  shall be made
unless and until the Person  requesting  such issue or delivery  has paid to the
Issuer the amount of any such tax or has established, to the satisfaction of the
Issuer, that such tax has been paid.

         SECTION  13.8  Issuer  to  Provide  Class A Common  Stock.  The  Issuer
covenants that it will reserve and keep available,  free from preemptive rights,
out of its authorized but unissued shares,  solely for the purpose of issue upon
conversion of Securities as herein provided, sufficient shares of Class A Common
Stock to provide for the conversion of the Securities  from time to time as such
Securities are presented for conversion.

         If any shares of Class A Common Stock to be reserved for the purpose of
conversion of Securities  hereunder require registration with or approval of any
governmental  authority under any Federal or State law before such shares may be
validly issued or delivered upon  conversion,  then the Issuer covenants that it
will in good faith and as  expeditiously  as  possible  endeavor  to secure such
registration or approval, as the case may be; provided, however, that nothing in
this Section shall be deemed to affect in any way the  obligations of the Issuer
to convert Securities into Class A Common Stock as provided in this Article.

         Before taking any action which would cause an  adjustment  reducing the
Conversion  Price below the then par value, if any, of the Class A Common Stock,
the Issuer will take all corporate  action which may, in the Opinion of Counsel,
be necessary  in order that the Issuer may validly and legally  issue fully paid
and  non-assessable  shares of Class A Common Stock at such adjusted  Conversion
Price.

         The Issuer  covenants that all shares of Class A Common Stock which may
be issued  upon  conversion  of  Securities  will upon issue be duly and validly
issued and fully paid and  non-assessable  by the Issuer and free of  preemptive
rights  and that,  if the Class A Common  Stock is then  listed on any  national
securities  exchange  or quoted on NASDAQ,  the  shares of Class A Common  Stock
which may be issued upon  conversion of Securities  will be similarly  listed or
quoted at the time of such issuance.

         The Issuer  covenants  that,  upon  conversion  of Securities as herein
provided,  there will be credited to Class A Common  Stock par capital  from the
consideration  for which the shares of Class A Common Stock  issuable  upon such
conversion  are issued an amount per share of Class A Common  Stock so issued as
determined  by the Board of  Directors,  which amount shall not be less than the
amount  required by law and by the Issuer's  certificate  of  incorporation,  as
amended,  as in effect on the date of such conversion.  For the purposes of this
covenant the net  proceeds  received by the Issuer from the issuance and sale of
the Convertible

                                      -71-



<PAGE>



Preferred  Stock  exchanged  for  the  Securities   converted,   less  any  cash
conversion,  shall be deemed to be the  amount  of  consideration  for which the
shares of Class A Common Stock issuable upon such conversion are issued.

         SECTION 13.9 Disclaimer of Responsibility for Certain Matters.  Neither
the Trustee nor any  Conversion  Agent or agent of the Trustee shall at any time
be under any duty or  responsibility  to any Holder of  Securities  to determine
whether  any facts exist which may  require  any  adjustment  of the  Conversion
Price,  or with  respect to the  Officers'  Certificate  referred  to in Section
13.4(g),  or with  respect to the nature or extent of any such  adjustment  when
made, or with respect to the method  employed,  or herein or in any supplemental
indenture  provided to be employed,  in making the same. Neither the Trustee nor
any  Conversion  Agent nor any agent of the Trustee  shall be  accountable  with
respect to the validity, registration, listing, or value (or the kind or amount)
of any shares of Class A Common  Stock,  or of any  securities  or cash or other
property,  which may at any time be issued or delivered  upon the  conversion of
any  Security;  and  neither  the  Trustee  nor any agent of the Trustee nor any
Conversion  Agent makes any  representation  with respect  thereto.  Neither the
Trustee  nor any  Conversion  Agent  nor  any  agent  of the  Trustee  shall  be
responsible  for any failure of the Issuer to make any cash payment or to issue,
register  the transfer of or deliver any shares of Class A Common Stock or stock
certificates or other  securities or property upon the surrender of any Security
for the purpose of  conversion  or,  subject to Sections  5.1 and 5.2, to comply
with any of the covenants of the Issuer contained in this Article.

         SECTION  13.10 Return of Funds  Deposited  for  Redemption of Converted
Securities.  Any funds which at any time shall have been deposited by the Issuer
or on its behalf with the Trustee or any other  Paying  Agent for the purpose of
paying the  principal of and interest on any of the  Securities  and which shall
not be required for such purposes  because of the conversion of such Securities,
as  provided in this  Article,  shall  after such  conversion,  upon the written
request  of the  Issuer,  be repaid to the  Issuer by the  Trustee or such other
paying agent.

                                ARTICLE FOURTEEN

                           RIGHT TO REQUIRE REDEMPTION

         SECTION  14.1 Right to Require  Redemption.  If at any time there shall
occur any Change in Control (as defined  below) of the Issuer,  then each Holder
shall have the right, at such Holder's option,  to require the Issuer to redeem,
and upon the exercise of such right the Issuer shall redeem,  all or any part of
such Holder's Securities that is $1,000 or any integral multiple thereof, on the
date (the "Repurchase Date") that is 45 days after the date of the Issuer Notice
(as defined  below) at a price in cash equal to the  principal  amount  thereof,
plus  accrued  and  unpaid  interest  to the  Repurchase  Date (the  "Repurchase
Price").

         SECTION 14.2 Notices;  Method of Exercising  Redemption Right, etc. (a)
Unless  the  Issuer  shall  have  theretofore  called  for  redemption  all  the
Securities then Outstanding  pursuant to Article Eleven of the Indenture,  on or
before the 30th day after the occurrence of a Change in Control,  the Issuer or,
at the request of the Issuer,  the Trustee,  shall mail to all holders of record
of the Securities a notice (the "Issuer Notice") of the occurrence of the Change
in Control  and of the  redemption  right set forth  herein  arising as a result
thereof in the manner  provided  in Section  10.4 of the  Indenture.  The Issuer
shall  also  deliver  a copy of the  Issuer  Notice to the  Trustee  prior to or
promptly after the mailing of such Issuer Notice.

         Each Issuer Notice shall state:

               (1) the Repurchase Date;

               (2) the date by which the  Securities  with respect to which such
          right is being exercised and the  irrevocable  written notice referred
          to in Section 14.2(b) must be delivered to the Trustee;

               (3) the Repurchase Price and accrued interest, if any;

               (4) a description of the procedure  which a Holder must follow to
          exercise  a  redemption  right  including  a form  of the  irrevocable
          written notice referred to in Section 14.2(b); and

               (5) the  Conversion  Price then in effect,  the date on which the
          right to convert the principal amount of the Securities to be redeemed
          will  terminate and the place or places where such  Securities  may be
          surrendered for conversion.

                                      -73-



<PAGE>


         No  failure  of the  Issuer to give the  Issuer  Notice  or any  defect
therein shall limit any Holder's right to exercise a redemption  right or affect
the validity of the proceedings for the redemption of Securities.

         (b) To  exercise a  redemption  right,  a Holder  shall  deliver to the
Trustee  on or  before  the 30th day  after the date of the  Issuer  Notice  (i)
irrevocable  written notice of the Holder's exercise of such right, which notice
shall set forth  the name of the  Holder,  the  amount of the  Securities  to be
redeemed  (which shall be in any authorized  denomination),  a statement that an
election to exercise the  redemption  right is being made thereby,  and (ii) the
Securities with respect to which the redemption right is being  exercised,  duly
endorsed for transfer to the Issuer.  Securities held by a securities depositary
may be  delivered  in such other  manner as may be agreed to by such  securities
depositary and the Issuer. Such written notice shall be irrevocable.  Subject to
the  provisions of paragraph (d) below,  Securities  surrendered  for redemption
together with such irrevocable written notice shall cease to be convertible from
the date of  delivery of such  notice.  If the  Repurchase  Date falls after the
record date and before the following interest payment date, any Securities to be
redeemed  must be  accompanied  by  payment of an amount  equal to the  interest
thereon  which the  registered  Holder  thereof is to  receive on such  interest
payment date, and,  notwithstanding such redemption,  such interest payment will
be made by the Issuer to the registered  Holder thereof on the applicable record
date.

         (c) In the event a redemption  right shall be  exercised in  accordance
with the terms hereof,  the Issuer shall pay or cause to be paid the  Repurchase
Price in cash, to the Holder on the Repurchase Date.

         (d) If any Security surrendered for redemption shall not be so redeemed
on the Repurchase  Date, such Security shall be convertible at any time from the
Repur chase Date until redeemed and, until  redeemed,  continue to bear interest
to the extent  permitted by applicable law from the Repurchase  Date at the same
rate borne by such Security. The Issuer shall pay to the Holder of such Security
the  additional  amount  arising as a result of the  provisions  of this Section
14.2(d) at the same time that it pays the  Repurchase  Price,  and if applicable
such Security shall remain convertible into Class A Common Stock until the

                                      -74-



<PAGE>



Repurchase  Price plus any additional  amounts owing on such Security shall have
been paid or duly provided for.

         (e)  Any  Security  which  is to be  redeemed  only in  part  shall  be
surrendered  at any office or agency of the Issuer  designated  for that purpose
pursuant to Section 2.3 (with,  if the Issuer or the  Trustee so  requires,  due
endorsement by, or a written  instrument of transfer in form satisfactory to the
Issuer and the Trustee duly executed by, the Holder thereof or his attorney duly
authorized  in writing),  and the Issuer shall  execute,  and the Trustee  shall
authenticate  and deliver to the Holder of such Security without service charge,
a new Security or  Securities,  of any authorized  denomination  as requested by
such  Holder,  in  aggregate  principal  amount equal to and in exchange for the
unredeemed portion of the Security so surrendered.

         SECTION 14.3 Definition of Change in Control.

         A "Change in Control" is deemed to have occurred when (i) any Person or
group (as the term  "person" or "group" is used in Section  13(d)(3) or 14(d)(2)
of the  Exchange  Act) other than  Stephen B.  Dodge,  Thomas H.  Stoner,  their
Related Parties or any person employed by the Issuer in a management capacity as
of June 19,  1996 (or any group in which any of them is a member,  collectively,
"a Permitted Owner") acquires  beneficial  ownership of, directly or indirectly,
shares of capital  stock of the Issuer  sufficient  to  entitle  such  person to
exercise more than 50% of the total voting power of all classes of capital stock
entitled  to vote in  elections  of  directors  (whether by means of an exchange
offer,   liquidation,   tender  offer,   consolidation,   merger,   combination,
reclassification,  recapitalization  or  otherwise),  or (ii) the Issuer  sells,
leases,  exchanges  or  transfers  (in one  transaction  or  series  of  related
transactions)  all or substantially all of its assets to any person or group (as
the term  "person"  or "group" is used in Section  13(d)(3)  or  14(d)(2) of the
Exchange Act), other than to one or more Permitted Owners.

         SECTION 14.4 Limitation on Right to Require Redemption. Notwithstanding
anything  herein to the  contrary,  no Holder  shall  have any right to  require
redemption  pursuant to this Article  Fourteen if either (i) the Last Sale Price
(or if on any such  Trading  Day the Class A Common  Stock is not  quoted by any
organization referred to in the definition of Last Sale Price, the fair value of

                          [FORM OF REVERSE OF SECURITY]

                       American Radio Systems Corporation

                 7% Convertible Subordinated Debentures Due 2011



         This Security is one of a duly  authorized  issue of debt securities of
the Issuer,  limited to up to the  aggregate  principal  amount of  $137,500,000
(except as otherwise  provided in the Indenture defined below),  issued or to be
issued  pursuant to an  indenture  dated as of June 25, 1996 (the  "Indenture"),
duly executed and delivered by the Issuer to Bank of Montreal Trust Company,  as
Trustee  (the  "Trustee").  Reference  is hereby made to the  Indenture  and all
indentures supplemental thereto for a description of the rights,  limitations of
rights, obligations, duties and immunities thereunder of the Trustee, the Issuer
and the Holders (the word "Holders" or "Holder"  meaning the registered  Holders
or  registered  Holder)  of the  Securities.  Capitalized  terms  used  but  not
otherwise  defined  herein  shall  have the  meanings  assigned  thereto  in the
Indenture.

         In case an Event of Default,  as defined in the  Indenture,  shall have
occurred and be  continuing,  the principal of all the  Securities  and interest
accrued  thereon may be  declared  due and  payable,  in the manner and with the
effect, and subject to the conditions,  provided in the Indenture. The Indenture
provides that in certain  events a  declaration  of default,  a default,  or the
consequences  of either of them may be waived by the  Holders of a  majority  in
aggregate  principal amount of the Securities then outstanding  except a default
in the payment of  principal  of or  premium,  if any, or interest on any of the
Securities or in respect of the  conversion of any of the  Securities.  Any such
consent or waiver by the Holder of this Security  (unless revoked as provided in
the  Indenture)  shall be  conclusive  and binding upon such Holder and upon all
future  Holders and owners of this Security and any Security which may be issued
in exchange or substitution hereof,  whether or not any notation thereof is made
upon this Security or such other Securities.

         The Indenture  permits the Issuer and the Trustee,  without the consent
of any of the Holders  under the  circumstances  described in Section 7.1 of the
Indenture,  and with the  consent of the  Holders of not less than a majority in
aggregate principal amount of the Securities at the time outstanding,  evidenced
as in the Indenture  provided,  to execute  supplemental  indentures  adding any
provisions to or

                                       -4-



<PAGE>



changing in any manner or eliminating  any of the provisions of the Indenture or
of any  supplemental  indenture  or  modifying  in any  manner the rights of the
Holders of the Securities;  provided,  that no such supplemental indenture shall
(a) extend the final  maturity of any Security,  or reduce the principal  amount
thereof or premium,  if any,  thereon,  or reduce the rate or extend the time of
payment of interest thereof,  or any premium payable on the redemption  thereof,
or change the place of payment  where,  or the coin or  currency  in which,  any
principal,  premium or  interest  is  payable,  or reduce or alter the method of
computation  of any amount  payable on redemption  thereof (or the time at which
such  redemption  may be made),  or impair or adversely  affect the right of any
Securityholder  to  institute  suit for the  payment  or  conversion  thereof or
adversely  affect the right to convert the Securities  into Class A Common Stock
of the Issuer,  in each case,  without the consent of the Holder of the Security
so  affected;  provided,  no  consent  of any  Holder  of any  Security  will be
necessary  to  permit  the  Trustee  and  the  Issuer  to  execute  supplemental
indentures under the  circumstances  provided in Section 7.1(e) and Section 13.5
of the  Indenture;,  or (b) reduce the aforesaid  percentage of Securities,  the
consent of the Holders of which is required for any such supplemental indenture,
without the consent of the Holders of each  Security so affected,  or (c) reduce
the  percentage  of  Securities  necessary  to consent to waive any past default
under the Indenture to less than a majority,  without the consent of the Holders
of each  Security so affected,  or (d) modify the  provisions  of the  Indenture
relating  to  subordination  of the  Securities  in any  manner  adverse  to the
Securityholders  without the consent of the Holder of each security so affected,
or (e) modify any of the  provisions of the Indenture  relating to  supplemental
indentures  or waivers  of past  defaults,  except to  increase  any  percentage
provided for in Section 4.10 or Section 7.2 of the  Indenture or to provide that
certain other  provisions of the Indenture  cannot be modified or waived without
the consent of the Holder of each Security affected thereby.

                  The Indebtedness evidenced by the Securities is, to the extent
         and in the manner provided in the Indenture,  expressly subordinate and
subject  in  right  of  payment  to the  prior  payment  in full  of all  Senior
Indebtedness of the Issuer as defined in the Indenture,  whether  outstanding at
the date of the  Indenture or thereafter  incurred,  and this Security is issued
subject to the provisions of the Indenture  with respect to such  subordination.
Each Holder of this  Security,  by  accepting  the same,  agrees to and shall be
bound by such  provisions  and authorizes the Trustee in his behalf to take such
action as may be necessary or

                                                  -5-

appropriate to effectuate the subordination so provided and appoints the Trustee
his attorney-in-fact for such purpose.

         Subject to the provisions of the Indenture, the Holder of this Security
has the right, at his option, at any time until and including, but not after the
close of business on, June 30, 2011  (except  that,  in case this  Security or a
portion  hereof  shall  be  called  for  redemption  and the  Issuer  shall  not
thereafter  default in making due  provision  for the payment of the  redemption
price,  such right shall terminate with respect to this Security or such portion
hereof at the close of business on the  Business Day prior to the date fixed for
redemption),  to convert the principal of this Security,  or any portion thereof
which  is  $1,000  or an  integral  multiple  of  $1,000,  into  fully  paid and
non-assessable  shares of Class A Common  Stock of the  Issuer,  as said  shares
shall be constituted at the date of conversion, at the conversion price of $____
in principal  amount of Securities  for each share of such Class A Common Stock,
or at the adjusted  conversion  price in effect at the date of  conversion if an
adjustment  has  been  made,  determined  as  provided  in the  Indenture,  upon
surrender  of this  Security to the Issuer at the office or agency of the Issuer
maintained  for that purpose in the Borough of Manhattan,  The City of New York,
together with a fully executed notice substantially in the form set forth at the
foot hereof that the Holder  elects so to convert this  Security (or any portion
hereof  which is an  integral  multiple  of  1,000)  and,  if this  Security  is
surrendered  for  conversion  during the period between the close of business on
March 15,  June 15,  September  15 or December 15 in any year and the opening of
business on the following March 31, June 30, September 30 or December 31 and has
not been called for  redemption  on a redemption  date within such period (or on
such March 31, June 30,  September 30 or December 31), or within five days after
such period,  accompanied by payment of an amount equal to the interest  payable
on such March 31, June 30,  September 30 or December 31 on the principal  amount
of the Security  being  surrendered  for  conversion.  Except as provided in the
preceding  sentence or as  otherwise  expressly  provided in the  Indenture,  no
payment  or  adjustment  shall be made on account  of  interest  accrued on this
Security  (or portion  thereof) so  converted  or on account of any  dividend or
distribution on any such Common Stock issued upon conversion,  but the Holder of
record of this Security on March 15, June 15,  September 15 or December 15 shall
be entitled to receive  interest on such  Security on the  succeeding  March 15,
June 15,  September 15 or December 15  notwithstanding  the  conversion  of such
Security  prior to such March 31, June 30,  September  30 or December  31. If so
required by the Issuer or the Trustee, this Security, upon

                                       -6-



<PAGE>



surrender  for  conversion  as  aforesaid,  shall  be duly  endorsed  by,  or be
accompanied by instruments of transfer, in form satisfactory to the Issuer, duly
executed by, the Holder or by his duly authorized attorney. The conversion price
from  time to time in  effect  is  subject  to  adjustment  as  provided  in the
Indenture.  No  fractions  of shares will be issued on  conversion.  In the sole
discretion of the Board of Directors,  any fractional interest may be rounded up
to the  nearest  full  share,  or an  adjustment  in cash  will be made  for any
fractional  interest,  in either case in accordance  with and as provided in the
Indenture.

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

         The  Securities  are issuable  only as  registered  Securities  without
coupons in denominations of $1,000 and any integral multiple of $1,000.

         In the manner and subject to the limitations provided in the Indenture,
this  Security  may  be  exchanged  for a like  aggregate  principal  amount  of
Securities of other authorized denominations.

         Upon due presentment  for  registration of transfer of this Security at
the above-mentioned office or agency of the Issuer, a new Security or Securities
of authorized  denominations,  for a like aggregate  principal  amount,  will be
issued to the transferee as provided in the  Indenture.  No service charge shall
be made for any such  transfer,  but the  Issuer  may  require  payment of a sum
sufficient to cover any tax or other governmental  charge that may be imposed in
relation thereto.

         The  Securities may be redeemed at the option of the Issuer as a whole,
or from time to time in part, on and after July 15, 1999,  upon mailing a notice
of such  redemption  not less  than 30 nor more  than 60 days  prior to the date
fixed for  redemption  to the  Holders  of  Securities  to be  redeemed,  all as
provided in the  Indenture,  at the following  redemption  prices  (expressed in
percentages of the principal amount) together in each case with accrued interest
to the date fixed for redemption:

         If at any time  there  shall  occur any Change in Control as defined in
the  Indenture  with  respect to the Issuer,  each Holder of  Securities  shall,
except as otherwise provided in the Indenture,  have the right, at such Holder's
option but subject to the conditions set forth in the Indenture,  to require the
Issuer to redeem on the  Repurchase  Date as defined in the Indenture all or any
part of such Holder's  Securities that is $1,000 or an integral multiple thereof
at a Repurchase  Price equal to the principal  amount thereof,  plus accrued and
unpaid interest, if any, up to but excluding the Repurchase Date.

due on redemption, interest on this Security (or portion hereof if this Security
is  redeemed  in part)  shall  cease to  accrue  upon the date  duly  fixed  for
redemption of this  Security (or portion  hereof if this Security is redeemed in
part).

         The Issuer,  the Trustee and any authorized  agent of the Issuer or the
Trustee may deem and treat the registered Holder hereof as the absolute owner of
this Security (whether or not this Security shall be overdue and notwithstanding
any notation of ownership or other writing  hereon made by anyone other than the
Issuer or the Trustee or any authorized agent of the Issuer or the Trustee), for
the purpose of receiving  payment of, or on account of, the principal hereof and
premium,  if any, and,  subject to the  provisions on the face hereof,  interest
hereon and for all other  purposes,  and  neither the Issuer nor the Trustee nor
any  authorized  agent of the Issuer or the  Trustee  shall be  affected  by any
notice to the contrary.

         No  recourse  shall  be had  for the  payment  of the  principal  of or

shown on, and the transfer of such ownership shall be effected through,  records
maintained by (i) DTC or its nominee for such DTC Receipt,  or (ii) institutions
that have accounts with DTC.

          If DTC subsequently  ceases to make its book-entry  settlement  system
available for the Receipts,  the Company may instruct the  Depositary  regarding
making  other  arrangements  for  book-entry  settlement.  In the event that the
Receipts are not eligible for, or it is no longer necessary to have the Receipts
available in book-entry form, the Depositary shall provide written  instructions
to DTC to deliver to the Depositary for  cancellation  the DTC Receipt,  and the
Company shall instruct the Depositary to deliver to the beneficial owners of the
Depositary Shares previously evidenced by the DTC Receipt definitive Receipts in
physical form evidencing such Depositary Shares.  Such definitive Receipts shall
be in substantially the form annexed hereto

                                       -4-



<PAGE>



as Exhibit A with appropriate insertions, modifications and
omissions, as hereafter provided.

          The  beneficial  owners of Depositary  Shares shall,  except as stated
above with respect to Depositary  Shares in book-entry  form  represented by the
DTC Receipt,  be entitled to receive Receipts in physical,  certificated form as
herein provided.

          The Receipts shall be typewritten, in the case of the DTC Receipt, and
otherwise  shall,  upon notice by the Company to the  Depositary,  be definitive
Receipts  which  shall  be  engraved,   printed  or  typewritten  and  shall  be
substantially  in the form set  forth  in  Exhibit  A  annexed  to this  Deposit
Agreement,   with  appropriate  insertions,   modifications  and  omissions,  as
hereinafter  provided.  The DTC Receipt shall bear such legend or legends as may
be  required  by DTC in order for it to accept  the  Depositary  Shares  for its
book-entry  settlement system.  Until such time as the Receipts are so engraved,
printed  or  typewritten  in  accordance  with  the  preceding   sentence,   the
Depositary, upon the written order of the Company or any holder of Stock, as the
case may be,  delivered in  compliance  with  Section  2.02,  shall  execute and
deliver  temporary  Receipts  which  are  printed,  lithographed,   typewritten,
mimeographed or otherwise  substantially of the tenor of the definitive Receipts
in lieu  of  which  they  are  issued  and  with  such  appropriate  insertions,
omissions,  substitutions  and other  variations as the persons  executing  such
Receipts may determine,  as evidenced by their  execution of such  Receipts.  If
temporary  Receipts  are  issued,  the  Company  and the  Depositary  will cause
definitive  Receipts  to be  prepared  without  unreasonable  delay.  After  the
preparation of definitive Receipts, the temporary Receipts shall be exchangeable
for  definitive  Receipts  upon  surrender  of  the  temporary  Receipts  at the
Depositary's   Office,   without  charge  to  the  holder.  Upon  surrender  for
cancellation of any one or more temporary Receipts, the Depositary shall execute
and deliver in  exchange  therefor  definitive  Receipts  representing  the same
number of Depositary Shares as represented by the surrendered  temporary Receipt
or Receipts.  Such exchange  shall be made at the Company's  expense and without
any charge  therefor  to the holder of the  Receipts.  Until so  exchanged,  the
temporary  Receipts shall in all respects be entitled to the same benefits under
this Deposit Agreement, and with respect to the Stock, as definitive Receipts.

          Receipts shall be executed by the  Depositary by the manual  signature
of a duly authorized  officer of the Depositary;  provided,  that such signature
may be a facsimile

                                       -5-



<PAGE>



if a Registrar  for the  Receipts  (other than the  Depositary)  shall have been
appointed  and such  Receipts are  countersigned  by manual  signature of a duly
authorized  officer  of the  Registrar.  No  Receipt  shall be  entitled  to any
benefits under this Deposit  Agreement or be valid or obligatory for any purpose
unless it shall have been executed manually by a duly authorized  officer of the
Depositary or, if a Registrar for the Receipts (other than the Depositary) shall
have been  appointed,  by manual or  facsimile  signature  of a duly  authorized
officer  of the  Depositary  and  countersigned  manually  by a duly  authorized
officer of such Registrar. The Depositary shall record on its books each Receipt
so signed  and  delivered  as  hereinafter  provided.  The  manual or  facsimile
signatures of individuals who were at any time proper officers of the Depositary
or the  Registrar,  as the case may be,  shall  constitute  adequate  signatures
hereunder,  notwithstanding  that such individuals or any of them have ceased to
hold such offices prior to the delivery of Receipts  bearing such  signatures or
did not hold such offices on the date of delivery of such Receipts.

          Except as the Depositary may otherwise determine, Receipts shall be in
denominations of any number of whole Depositary Shares.

          Receipts may be endorsed with or have incorporated in the text thereof
such legends or recitals or changes not inconsistent with the provisions of this
Deposit  Agreement as may be required by the National  Association of Securities
Dealers  Inc. in order for the  Receipts to be  tradeable on PORTAL or as may be
required for the Receipts to be  tradeable  on any other  market  developed  for
trading of securities pursuant to Rule 144A under the Securities Act or required
to comply with any applicable law or any regulation thereunder or with the rules
and regulations of any securities  exchange upon which the Stock, the Depositary
Shares or the  Receipts  may be listed or to conform with any usage with respect
thereto,  or to indicate any special  limitations or  restrictions  to which any
particular Receipts are subject.

          Subject to any  limitations  set forth in a Receipt or in this Deposit
Agreement,  title to a Receipt (and to the Depositary  Shares  evidenced by such
Receipt)  which is  properly  endorsed  or  accompanied  by a properly  executed
instrument of transfer,  shall be  transferable by delivery with the same effect
as in the  case  of a  negotiable  instrument;  provided,  however,  that  until
transfer of a Receipt  shall be  registered  on the books of the  Depositary  as
provided in Section 2.04, the Depositary may,

                                       -6-


<PAGE>



notwithstanding  any notice to the contrary,  treat the record holder thereof at
such time as the  absolute  owner  thereof  for the purpose of  determining  the
person  entitled to  distributions  of  dividends  or other  distributions,  the
exercise of conversion  rights, the exchange of Depositary Shares for Stock, the
right to exchange  Receipts  pursuant to Section 2.10 or to any notice  provided
for in this Deposit Agreement and for all other purposes.

          The  Depositary  (and any  Registrar  acting on its behalf) shall not,
prior to the  removal of the  legends set forth on Exhibit A pursuant to Section
2.12 hereof,  register the transfer of any Receipt by an Accredited  Investor or
an Offshore  Investor  except upon the  delivery by the  Accredited  Investor or
Offshore Investor to the Depositary of such  certification and other evidence as
the  Depositary  may  reasonably  require to confirm that the proposed  transfer
complies with the resale  restrictions stated in the restrictive legend included
on the form of Receipt set forth as Exhibit A hereto.

          SECTION 2.02. Deposit of Stock;  Execution and Delivery of Receipts in
Respect Thereof.  Subject to the terms and conditions of this Deposit Agreement,
the Company or an Original Purchaser may from time to time deposit shares of the
Stock with the  Depositary  under this  Deposit  Agreement  by  delivery  to the
Depositary of the  certificate  or  certificates  for the Stock to be deposited,
properly endorsed or accompanied,  if required by law or by the Depositary, by a
duly executed instrument of transfer or endorsement, in form satisfactory to the
Depositary,  together  with all such  certifications  as may be  required by the
Depositary in accordance  with the  provisions  of this Deposit  Agreement,  and
together  with a written order of the Company or an Original  Purchaser,  as the
case may be,  directing  the  Depositary  to execute and deliver to, or upon the
written  order of,  the  person or  persons  stated in such  order a Receipt  or
Receipts for the number of Depositary Shares representing such deposited Stock.

          Deposited  Stock shall be held by the  Depositary at the  Depositary's
Office or at such other place or places as the Depositary shall determine.

          Upon receipt by the  Depositary of a certificate or  certificates  for
Stock deposited in accordance with the provisions of this Section, together with
the other documents  required as above  specified,  and upon  recordation of the
Stock on the books of the Company in the name of the  Depositary or its nominee,
the Depositary,  subject to the terms and conditions of this Deposit  Agreement,
shall

                                       -7-


<PAGE>



execute  and  deliver,  to or upon  the  order  of the  Company  or an  Original
Purchaser,   a  Receipt  or  Receipts  for  the  number  of  Depositary   Shares
representing  the Stock so deposited and registered in such name or names as may
be requested by the Company or such Original  Purchaser.  The  Depositary  shall
execute and deliver such Receipt or Receipts at the Depositary's  Office or such
other  offices,  if any,  as the  Depositary  may  designate.  Delivery at other
offices shall be at the risk and expense of the person requesting such delivery.
The DTC Receipt  shall provide that it shall  evidence the  aggregate  amount of
Depositary  Shares from time to time  indicated in the records of the Depositary
and that the aggregate amount of Depositary Shares evidenced thereby may from to
time be  increased or  decreased  by making  adjustments  on such records of the
Depositary.

          Other   than  in  the   case  of   splits,   combinations   or   other
reclassifications  affecting  the Stock,  or in the case of  dividends  or other
distributions of Stock, if any, there shall be deposited hereunder not more than
137,500 shares of Stock.

          SECTION  2.03.  Redemption  of Stock.  Whenever  the Company  shall be
permitted  and shall  elect to redeem  shares  of Stock in  accordance  with the
provisions of the Certificate,  it shall (unless  otherwise agreed to in writing
with the Depositary)  give the Depositary not more than 30 days' or less than 60
days' notice of the date of such proposed  redemption of Stock and of the number
of such  shares held by the  Depositary  to be so  redeemed  and the  applicable
redemption  price,  as set  forth  in the  Certificate,  which  notice  shall be
accompanied by a certificate  from the Company  stating that such  redemption of
Stock is in accordance  with the provisions of the  Certificate.  On the date of
such  redemption,  provided that the Company shall then have paid in full to the
Depositary  the redemption  price of the Stock to be redeemed,  plus any accrued
and  unpaid  dividends  thereon,  in  accordance  with  the  provisions  of  the
Certificate,  the  Depositary  shall  redeem  the  number of  Depositary  Shares
representing  such Stock.  The  Depositary  shall mail  notice of the  Company's
redemption  of Stock and the proposed  simultaneous  redemption of the number of
Depositary  Shares  representing  the Stock to be redeemed by first-class  mail,
postage  prepaid,  not less than 30 and not more than 60 days  prior to the date
fixed for  redemption  of such  Stock and  Depositary  Shares  (the  "Redemption
Date"),  to the Record Holders of the Receipts  evidencing the Depositary Shares
to be so  redeemed,  at the  addresses  of such  holders  as they  appear on the
records  of the  Depositary;  but  neither  failure  to mail any such  notice of
redemption of Depositary Shares to one or more such

                                       -8-


<PAGE>



holders nor any defect in any notice of redemption  of Depositary  Shares to one
or more such  holders  shall  affect  the  sufficiency  of the  proceedings  for
redemption  as to the other  holders.  Each such  notice  shall  state:  (i) the
Redemption  Date;  (ii) the number of  Depositary  Shares to be redeemed and, if
less than all the Depositary  Shares held by any such holder are to be redeemed,
the number of such  Depositary  Shares  held by such  holder to be so  redeemed;
(iii) the redemption price;  (iv) the place or places where Receipts  evidencing
Depositary Shares are to be surrendered for payment of the redemption price; (v)
the then current  conversion  price;  and (vi) that  dividends in respect of the
Stock  represented by the Depositary  Shares to be redeemed will cease to accrue
on such Redemption Date. In case less than all the outstanding Depositary Shares
are to be redeemed, the Depositary Shares to be so redeemed shall be selected by
lot or pro rata as may be determined by the Depositary to be equitable.

          Notice having been mailed by the  Depositary  as  aforesaid,  from and
after the  Redemption  Date (unless the Company shall have failed to provide the
funds  necessary to redeem the Stock  evidenced by the Depositary  Shares called
for  redemption)  (i) dividends on the shares of Stock so called for  redemption
shall cease to accrue after such date, (ii) the Depositary Shares being redeemed
from such proceeds shall be deemed no longer to be outstanding, (iii) all rights
of the holders of Receipts  evidencing such Depositary  Shares (except the right
to receive the redemption price) shall, to the extent of such Depositary Shares,
cease and terminate,  and (iv) upon surrender in accordance with such redemption
notice  of the  Receipts  evidencing  any  such  Depositary  Shares  called  for
redemption  (properly  endorsed or assigned for transfer,  if the  Depositary or
applicable law shall so require),  such  Depositary  Shares shall be redeemed by
the Depositary at a redemption price per Depositary Share equal to 1/20th of the
redemption  price per share paid in  respect of the shares of Stock so  redeemed
plus all  money and  other  property,  if any,  represented  by such  Depositary
Shares,  including all amounts paid by the Company in respect of dividends which
on the Redemption Date have accumulated on the shares of Stock to be so redeemed
and have not theretofore been paid.

          If fewer than all of the Depositary  Shares evidenced by a Receipt are
called for redemption, the Depositary will deliver to the holder of such Receipt
upon its surrender to the Depositary,  together with the redemption  payment,  a
new Receipt evidencing the Depositary Shares evidenced by such prior Receipt and
not called for redemption.

          SECTION  2.04.  Transfer  of  Receipts.   Subject  to  the  terms  and
conditions of this Deposit Agreement (including,  without limitation,  the final
paragraph of Section 2.01), the Depositary shall register on its books from time
to time transfers of Receipts upon any surrender thereof by the holder in person
or by a duly authorized attorney, properly endorsed or accompanied by a properly
executed instrument of transfer and any necessary certifications.  Thereupon the
Depositary shall execute a new Receipt or Receipts evidencing the same aggregate
number of  Depositary  Shares as those  evidenced  by the  Receipt  or  Receipts
surrendered and deliver such new Receipt or Receipts to or upon the order of the
person entitled thereto.

          SECTION 2.05.  Split-ups and  Combinations  of Receipts;  Surrender of
Receipts and  Withdrawal  of Stock.  Upon  surrender by a holder of a Receipt or
Receipts at the Depositary's Office or at such other offices as it may designate
for the  purpose of  effecting  a split-up  or  combination  of such  Receipt or
Receipts,  the Depositary shall execute and deliver a new Receipt or Receipts in
the authorized denomination or denominations requested, evidencing the aggregate
number of Depositary Shares evidenced by the Receipt or Receipts surrendered. In
connection  with any  split-up or  combination  pursuant to this  paragraph  not
involving a transfer of  Receipts,  the  Depositary  shall not be  obligated  to
obtain any certification or endorsement  otherwise required by the terms of this
Deposit Agreement.

          Any holder of a Receipt or Receipts  representing  any number of whole
shares of Stock or his duly  authorized  attorney may withdraw the Stock and all
money and other  property,  if any,  represented  thereby by  surrendering  such
Receipt or Receipts,  at the Depositary's Office or at such other offices as the
Depositary  may designate  for such  withdrawals.  If such  holder's  Depositary
Shares are being held by DTC or its  nominee  pursuant  to  Section  2.01,  such
holder shall  request,  in  accordance  with and subject to the  limitations  in
Section 2.11,  withdrawal from the book-entry system of the number of Depositary
Shares specified in the preceding  sentence.  Thereafter,  without  unreasonable
delay,  the Depositary  shall deliver to such holder or to the person or persons
designated by such holder as hereinafter provided, the number of whole shares of
Stock and all money and other  property,  if any,  represented by the Receipt or
Receipts so  surrendered  for  withdrawal,  but holders of such whole  shares of
Stock will not  thereafter  be entitled to deposit  such Stock  hereunder  or to
receive Depositary Shares therefor. If a Receipt delivered by the holder to the

                                      -10-


<PAGE>



Depositary  in  connection  with  such  withdrawal  shall  evidence  a number of
Depositary Shares in excess of the number of Depositary Shares  representing the
number of whole shares of Stock to be so withdrawn,  the Depositary shall at the
same time,  in addition  to such number of whole  shares of Stock and such money
and other property, if any, to be so withdrawn,  deliver to such holder, or upon
his  order or to the  person  or  persons  stated in the  order,  a new  Receipt
evidencing such excess number of Depositary  Shares. In no event will fractional
shares of Stock be  distributed  by the  Depositary.  Delivery  of the Stock and
money and other  property  being  withdrawn  may be made by the delivery of such
certificates,  documents of title and other  instruments  as the  Depositary may
deem appropriate.

          Stock  delivered  pursuant to the preceding  paragraph may be endorsed
with or have  incorporated  in the text  thereof  such  legends or  recitals  or
changes not inconsistent with the provisions of this Deposit Agreement as may be
required to comply with any applicable  law or any  regulation  thereunder or to
conform  with any  usage  with  respect  thereto,  or to  indicate  any  special
limitations or restrictions to which any particular shares of Stock are subject.

          If the Stock and the money and other property  being  withdrawn are to
be delivered to a person or persons  other than the Record Holder of the Receipt
or Receipts being surrendered for withdrawal of Stock, such holder shall execute
and deliver to the  Depositary a written order so directing the  Depositary  and
the  Depositary  may require  that the Receipt or Receipts  surrendered  by such
holder for  withdrawal of such shares of Stock be properly  endorsed in blank or
accompanied by a properly executed instrument of transfer in blank. In addition,
if the Record Holder of the Receipt being surrendered for withdrawal of Stock is
an Accredited Investor or an Offshore Investor, the Depositary shall not deliver
the Stock to, and such Stock shall not be  registered in the name of, any person
other  than such  Accredited  Investor  or  Offshore  Investor  except  upon the
delivery by such Accredited  Investor or Offshore  Investor to the Depositary of
such  certification and other evidence as the Depositary may reasonably  require
to confirm  that the proposed  transfer  complies  with the resale  restrictions
stated in the  restrictive  legend  included on the form of Receipt set forth as
Exhibit A hereto.

          Delivery  of the  Stock and the  money  and  other  property,  if any,
represented  by  Receipts  surrendered  for  withdrawal  shall  be  made  by the
Depositary at the Depositary's Office, except that, at the request, risk and

                                      -11-


<PAGE>



expense of the holder  surrendering such Receipt or Receipts and for the account
of the holder  thereof,  such delivery may be made at such other place as may be
designated by such holder.

          SECTION  2.06.  Limitations  on  Execution  and  Delivery,   Transfer,
Surrender  and Exchange of Receipts.  As a condition  precedent to the execution
and  delivery,  transfer,  split-up,  combination,  surrender or exchange of any
Receipt,  the  Depositary,  any of the  Depositary's  Agents or the  Company may
require payment to it of a sum sufficient for the payment (or, in the event that
the Depositary or the Company shall have made such payment, the reimbursement to
it) of any  charges or expenses  payable by the holder of a Receipt  pursuant to
Section 5.07 (or reasonably satisfactory evidence that such charges and expenses
have been paid), may require the production of evidence satisfactory to it as to
the identity and  genuineness  of any signature and may also require  compliance
with such  regulations,  if any, as the  Depositary or the Company may establish
consistent with the provisions of this Deposit Agreement.

          The deposit of Stock may be refused,  the delivery of Receipts against
Stock may be suspended,  the registration of transfer of Receipts may be refused
and the registration of transfer,  surrender or exchange of outstanding Receipts
may be suspended  during (i) any period when the register of stockholders of the
Company is closed or (ii) if required by law or any  government or  governmental
body or commission or (iii) under any provision of this Deposit Agreement or the
Purchase Agreement.

          The  transfer or  surrender of Receipts by  Accredited  Investors  and
Offshore  Investors  shall,  in addition to the foregoing  limitations,  also be
subject to the applicable  restrictions stated in the final paragraph of Section
2.01 and the penultimate paragraph of Section 2.05.

          SECTION  2.07.  Lost  Receipts,  etc.  In case  any  Receipt  shall be
mutilated,  destroyed,  lost or stolen,  the  Depositary  may in its  discretion
execute  and  deliver  a  Receipt  of  like  form  and  tenor  in  exchange  and
substitution for such mutilated  Receipt,  or in lieu of and in substitution for
such  destroyed,  lost or stolen  Receipt,  upon (i) the  filing  by the  holder
thereof with the Depositary of evidence  satisfactory  to the Depositary of such
destruction or loss or theft of such Receipt, of the authenticity thereof and of
his or her  ownership  thereof  and (ii) the  furnishing  to the  Depositary  of
reasonable indemnification satisfactory to it.

<PAGE>



          SECTION 2.08.  Cancellation  and Destruction of Surrendered  Receipts.
All Receipts physically  surrendered to the Depositary or any Depositary's Agent
shall be cancelled by the Depositary.  Except as prohibited by applicable law or
regulation,  the  Depositary is authorized to destroy all Receipts so cancelled.
Any Receipt  evidenced in  book-entry  form shall be deemed  cancelled  when the
Depositary  has caused  the amount of  Depositary  Shares  evidenced  by the DTC
Receipt to be reduced in proportion to the number of Depositary Shares evidenced
by the surrendered Receipt.

          SECTION 2.09.  Conversion  Rights.  Receipts may be  surrendered  with
written  instructions  to the  Depositary  to instruct  the Company to cause the
conversion  of any  specified  number  of whole or  fractional  shares  of Stock
represented  by the  Depositary  Shares  evidenced  thereby into whole shares of
Common  Stock  at the  conversion  price  then in  effect  for the  Stock  (and,
therefore,  for the Depositary  Shares)  specified in the  Certificate,  as such
conversion price may be adjusted by the Company from time to time as provided in
the Certificate.  Subject to the terms and conditions of this Deposit  Agreement
and the  Certificate,  a holder of a Receipt or Receipts  evidencing  Depositary
Shares  representing  whole or  fractional  shares of Stock may  surrender  such
Receipt or  Receipts to the  Depositary  at the  Depositary's  Office or to such
office or to such  Depositary's  Agents as the Depositary may designate for such
purpose,  together  with (i) a notice of conversion  thereof duly  completed and
executed  (a  "Notice  of  Conversion"),  and (ii) any  payment  in  respect  of
dividends  required  by the  fourth  paragraph  of this  Section  2.09,  thereby
directing the  Depositary to instruct the Company to cause the conversion of the
number of shares or  fractions  thereof of  underlying  Stock  specified in such
Notice  of  Conversion  into  whole  shares of Common  Stock.  If such  holder's
Depositary Shares are being held by DTC or its nominee pursuant to Section 2.01,
such  holder  shall  request,  pursuant  to Section  2.11,  withdrawal  from the
book-entry system the number of Depositary Shares to be converted.  In the event
that a holder  delivers to the  Depositary  for conversion a Receipt or Receipts
which in the aggregate are convertible  into less than one whole share of Common
Stock,  the holder shall receive  payment in lieu of such  fractional  shares of
Common Stock  otherwise  issuable in accordance  with the last paragraph of this
Section 2.09.

          Upon receipt by the Depositary of a Receipt or Receipts, together with
a Notice of Conversion, duly completed and executed, directing the Depositary to
instruct the Company to cause the conversion of a specified number of

                                      -13-

<PAGE>



shares or fractions  thereof of Stock, the Depositary shall instruct the Company
(i) to cause the conversion of the Depositary  Shares  evidenced by the Receipts
so  surrendered  for conversion as specified in the written Notice of Conversion
to the Depositary and (ii) to cause the delivery to the holders of such Receipts
a certificate  or  certificates  evidencing the number of whole shares of Common
Stock, and the amount of immediately available funds, if any, to be delivered to
the holders of Receipts  surrendered for conversion in payment of any fractional
shares of Common Stock  otherwise  issuable.  The Company shall,  as promptly as
practicable  after receipt  thereof,  cause the delivery of (i) a certificate or
certificates  evidencing  the number of whole  shares of Common Stock into which
the Stock  represented  by the  Depositary  Shares  evidenced by such Receipt or
Receipts has been  converted,  and (ii) any money or other property to which the
holder is entitled. The person or persons in whose name or names any certificate
or  certificates  for  shares  of  Common  Stock  shall be  issuable  upon  such
conversion shall be deemed to have become the holder or holders of record of the
shares represented  thereby at the close of business on the date such Receipt or
Receipts shall have been  surrendered to and a Notice of Conversion  received by
the  Depositary,  unless the stock transfer books of the Company shall be closed
on that  date,  in which  event such  person or persons  shall be deemed to have
become such holder or holders of record on the next succeeding day on which such
stock transfer books are open.  Upon such  conversion,  the Depositary (i) shall
deliver to the holder a Receipt  evidencing the number of Depositary  Shares, if
any,  which such holder has elected not to convert  evidenced by such Receipt or
Receipts in excess of the number of Depositary Shares  representing  Stock which
has been so  converted,  (ii) shall cancel the  Depositary  Shares  evidenced by
Receipts  surrendered for conversion and (iii) shall deliver for cancellation to
the  transfer  agent  for the  Stock  the  shares  of Stock  represented  by the
Depositary Shares evidenced by the Receipts so surrendered and so converted.

          If any  Stock  shall  be  called  by the  Company  for  redemption  or
exchange,  the Depositary  Shares  representing such Stock may be converted into
Common Stock as provided in this Deposit  Agreement  until and  including,  but,
except as may be provided in the  Certificate,  not after, the close of business
on the day prior to the Redemption Date or the close of business on the Exchange
Date, as the case may be, unless the Company shall default in making  payment of
the cash  redemption  price or the delivery of the Exchange  Debentures,  as the
case may be,  and the  payment  of other  amounts,  if any,  payable  upon  such
redemption or exchange,  in which case the Depositary  Shares  representing such
Stock

                                      -14-


<PAGE>



may continue to be  converted  into Common  Stock until and  including,  but not
after, the close of business on the date on which the Company makes full payment
of the cash redemption price or delivery of the Exchange  Debentures and payment
of other amounts,  if any,  payable on such redemption or exchange,  as the case
may be. Upon receipt by the Depositary of a Receipt or Receipts, together with a
properly  completed and executed  Notice of Conversion,  representing  any Stock
called for  redemption or exchange,  the shares of Stock held by the  Depositary
represented by such Depositary Shares for which conversion is requested shall be
deemed to have been received by the Company for conversion.

          Upon any conversion of the Stock underlying the Depositary  Shares, no
allowance, adjustment or payment shall be made with respect to accrued dividends
upon such Stock except that if any holder of a Receipt  surrenders  such Receipt
with  instructions  to the Depositary  for  conversion of the  underlying  Stock
evidenced  thereby  during  the  period  between  the close of  business  on any
dividend record date and the opening of business on the  corresponding  dividend
payment date (except  shares called for  redemption on a Redemption  Date during
such period or shares being  exchanged on an Exchange  Date during such period),
such Receipt must be accompanied by a payment equal to the dividend thereon,  if
any,  which the holder of record of such  Receipt is entitled to receive on such
dividend payment date in respect of the underlying Stock to be converted.

          Upon the  conversion  of any  shares of Stock for which a request  for
conversion has been made by the holder of Depositary  Shares  representing  such
shares,  all  dividends  in respect of such  Depositary  Shares  shall  cease to
accrue, such Depositary Shares shall be deemed no longer outstanding, all rights
of the holder of the Receipt with respect to such Depositary  Shares (except the
right to  receive  the  Common  Stock,  any cash  payable  with  respect  to any
fractional  shares of Common  Stock as provided  herein and any cash  payable on
account  of accrued  dividends  in  respect  of the Stock so  converted  and any
Receipts evidencing Depositary Shares not so converted) shall terminate, and the
Receipt  evidencing such Depositary Shares shall be cancelled in accordance with
Section 2.08 hereof.

          No fractional shares of Common Stock shall be issuable upon conversion
of Stock underlying the Depositary  Shares except as hereinafter  provided.  If,
except for the provisions of this Section 2.09 and the  Certificate,  any holder
of Receipts  surrendered  with  instructions to the Depositary for conversion of
the underlying Stock would be

                                      -15-

entitled to a fractional share of Common Stock upon such conversion, the Company
shall cause to be delivered to such holder an amount,  in immediately  available
funds, for such fractional share based upon the last reported sale price then in
effect  for  the  Common  Stock  on  such  date  computed  as set  forth  in the
Certificate  unless  payment in cash is prohibited by the terms of the Company's
indebtedness,  in which case  fractional  shares  will be issued or, at the sole
option of the Company, such fractional shares shall be rounded up to the nearest
full share.

          SECTION  2.10.  Exchange.  On the  Exchange  Date,  provided  that the
Company shall then have delivered to the Depositary the Exchange  Debentures and
the aggregate  amount of cash  required to pay any accrued and unpaid  dividends
and cash in respect of any principal amount of Exchange Debentures less than the
minimum denomination that is issuable and payable with respect to the Stock then
deposited with the Depositary,  the Depositary  shall deliver to each holder the
proportionate  amount  of  such  Exchange  Debentures  (subject  to the  minimum
denomination  requirements of such Exchange Debentures referred to below in this
Section  2.10)  and cash so  delivered  to the  Depositary  in  respect  of such
holder's Depositary Shares.

          The Depositary  shall, as directed by the Company,  mail,  first class
postage prepaid,  notice of such Exchange of Stock and the proposed simultaneous
exchange of the  Depositary  Shares,  not less than 30 and not more than 60 days
prior to the  Exchange  Date.  Such notice shall be mailed to each holder at the
address of such holder as the same appears on the records of the  Depositary  at
the close of business on the second business day immediately  preceding the date
on which the mailing of such notices is commenced;  but neither  failure to mail
any such notice to one or more holders nor any defect in any notice shall affect
the sufficiency of the  proceedings for the exchange.  The Company shall provide
the Depositary with such notice,  and each such notice shall state: the Exchange
Date;  that  all  outstanding  shares  of  Stock on the  Exchange  Date  will be
exchanged for Exchange Debentures; that all outstanding Depositary Shares on the
Exchange Date will in turn be exchanged for such Exchange Debentures; the amount
of accrued and unpaid dividends, if any, payable with respect to each Depositary
Share to be so exchanged;  the place or places where Receipts to be so exchanged
are to be  surrendered  for  exchange;  that  dividends  in respect of the Stock
represented by the Depositary Shares to be so exchanged shall cease to accrue at
the  close of  business  on the day  prior to the  Exchange  Date;  the  minimum
principal amount in which Exchange Debentures shall be issued; the

                                      -16-


<PAGE>



then current  conversion price and the last date on which Depositary  Shares may
be converted;  and such additional  information as the Company in its discretion
deems appropriate.

          From and after the  Exchange  Date,  the  Depositary  Shares  shall be
deemed no longer to be  outstanding  and all rights of the  holders of  Receipts
evidencing  such  Depositary  Shares  (except the right to receive the  Exchange
Debentures  and any cash payable upon the Exchange)  shall cease and  terminate.
Upon  surrender,  in  accordance  with the  notice  specified  in the  preceding
paragraph,  of the Receipts evidencing such Depositary Shares (properly endorsed
or assigned for transfer,  if the Depositary shall so require), a holder of such
Receipts  shall  receive for such  holder's  Depositary  Shares,  subject to the
following  sentence,  the Exchange  Debentures  issued in exchange for the Stock
represented by such Depositary  Shares,  and an amount of cash equal to the cash
for accrued and unpaid dividends,  if any, delivered in respect of the exchanged
Stock  represented by such Depositary  Shares. An amount of cash will be paid to
holders in respect of any  principal  amount of  Exchange  Debentures  otherwise
issuable which is less than $1,000, or such other minimum  denomination as shall
be  specified  in  the  notice  referred  to in  the  preceding  paragraph.  The
Depositary  shall,  at the  written  direction  of the  Company,  sell  Exchange
Debentures  delivered  by the  Company  in  exchange  for Stock  that  shall not
otherwise  be  distributable  to holders of  Depositary  Shares  because of such
minimum  denomination  and shall  distribute the proceeds  thereof in payment of
cash amounts  payable to holders of Depositary  Shares pursuant to the preceding
sentence.  The foregoing shall be subject further to the terms and conditions of
the Certificate.

          SECTION  2.11.   Exchange  of  Book-Entry  Receipts  and  Receipts  in
Physical, Certificated Form. Beneficial interests in Depositary Shares evidenced
by a DTC Receipt may only be exchanged  for  Receipts in physical,  certificated
form upon the transfer of such beneficial  interest by a holder thereof pursuant
to Regulation S under the Securities Act. Subject to the terms and conditions of
this Deposit  Agreement,  upon such  transfer,  the  beneficial  interest  being
transferred  in the DTC Receipt may not continue to be held in  book-entry  form
through DTC and,  in exchange  therefor,  the  Depositary  shall (i) execute and
deliver a Receipt in physical,  certificated  form  evidencing  such  Depositary
Shares;  (ii) follow the  procedures  set forth in paragraph 19 of the Letter of
Representations  attached  hereto as Exhibit B for the purpose of  reducing  the
number of Depositary Shares evidenced by the DTC Receipt; and (iii) following

                                      -17-


<PAGE>



such  reduction,  execute  and  deliver  to or upon the  order of the  person or
persons  named in such order a Receipt  or  Receipts  registered  in the name or
names  requested by such person and  evidencing  in the  aggregate the number of
Depositary  Shares  equal to the  reduction  in the number  evidenced by the DTC
Receipt  subject,  however,  in the case of  Accredited  Investors  and Offshore
Investors to the final  paragraph of Section 2.01. The Depositary may require in
such written  instructions any  certification or representation as it shall deem
necessary to comply with applicable law.

          Depositary  Shares  initially sold to Accredited  Investors or sold to
Offshore  Investors  pursuant to Regulation S under the  Securities Act shall be
issued in physical,  certificated form. Receipts in physical,  certificated form
may only be exchanged for beneficial interests in Depositary Shares evidenced by
a DTC Receipt (a) upon the transfer of any such Receipts initially sold pursuant
to Regulation S under the  Securities  Act (i) to a QIB in reliance on Rule 144A
under the  Securities  Act or (ii) following the expiration of the 40-day period
following  the last issue date for the Stock issued to cover over  allotments or
(b) upon the  transfer  of any such  Receipts  initially  sold to an  Accredited
Investor to a QIB in reliance on Rule 144A under the Securities Act.  Subject to
the terms and  conditions of this Deposit  Agreement,  upon any such transfer of
such  Receipts,  duly endorsed or  accompanied  by  appropriate  instruments  of
transfer,  in  form  satisfactory  to the  Depositary,  including  any  required
certifications,  following  receipt by the  Depositary  of written  instructions
directing  the  Depositary  to adjust its  records to reflect an increase in the
aggregate amount of Depositary  Shares evidenced by the DTC Receipt  (including,
without  limitation,  information  regarding the DTC  participant  account to be
credited with such  increase),  and upon payment of the fees and expenses of the
Depositary,  the  Depositary  shall cancel such Receipt or Receipts in physical,
certificated  form and shall follow the  procedures set forth in paragraph 20 of
the Letter of  Representations  attached  hereto as Exhibit B for the purpose of
reflecting such increase in the number of Depositary Shares evidenced by the DTC
Receipt.

          SECTION 2.12. Removal of Legends.  The legends provided on the face of
the text of the  Receipts  attached as Exhibit A hereto may be removed  from any
Receipt, upon receipt by the Depositary of a written order signed in the name of
the  Company by its  Chairman of the Board,  its Chief  Executive  Officer,  its
President,  a Chief Operating Officer, a Vice President,  or its Chief Financial
Officer, and, without duplication, by its Treasurer, an Assistant

                                      -18-


<PAGE>



Treasurer,  its  Controller,  its  Secretary or an Assistant  Secretary,  of the
Issuer,  (i) three  years from the later of  issuance of the Receipt or the date
such Receipt (or any  predecessor)  was last acquired from an "affiliate" of the
Company  within  the  meaning  of Rule 144 under the  Securities  Act or (ii) in
connection with a sale made pursuant to the volume (and other  restrictions)  of
Rule 144 under the Securities  Act following two years from such time,  provided
that, if the legend is removed and the Receipt is  subsequently  held by such an
affiliate of the Company, the legend shall be reinstated.

                                   ARTICLE III

                             Certain Obligations of
                       Holders of Receipts and the Company

          SECTION 3.01. Filing Proofs,  Certificates and Other Information.  Any
holder  of a Receipt  may be  required  from time to time to file such  proof of
residence,  or other matters or other information,  to execute such certificates
and to make such representations and warranties as the Depositary or the Company
may  reasonably  deem  necessary or proper.  The  Depositary  or the Company may
withhold  the  delivery,  or delay the  registration  of  transfer,  redemption,
conversion  or  exchange,  of  any  Receipt  or  the  withdrawal  of  the  Stock
represented  by  the  Depositary   Shares   evidenced  by  any  Receipt  or  the
distribution of any dividend or other  distribution or the sale of any rights or
of the proceeds thereof or the exercise of any conversion rights as specified in
Section 2.09 until such proof or other information is filed or such certificates
are executed or such representations and warranties are made.

          SECTION  3.02.  Payment of Charges and  Expenses.  Holders of Receipts
shall be obligated to make  payments to the  Depositary  of certain  charges and
expenses,  as  provided  in Section  5.07,  or provide  reasonably  satisfactory
evidence that such charges and expenses have been paid. Registration of transfer
of any Receipt,  conversion  rights or any  withdrawal of Stock and all money or
other property,  if any,  represented by the Depositary Shares evidenced by such
Receipt may be refused  until any such payment due is made,  and any  dividends,
interest  payments or other  distributions  may be withheld and such  conversion
right  may be  refused  or any  part  of or all  the  Stock  or  other  property
represented  by  the  Depositary  Shares  evidenced  by  such  Receipt  and  not
theretofore  sold may be sold  for the  account  of the  holder  thereof  (after
attempting  by reasonable  means to notify such holder prior to such sale),  and
such dividends,  interest payments or other distributions or the proceeds of any
such

                                      -19-


<PAGE>



sale may be applied to and payment of such  charges or  expenses,  the holder of
such Receipt remaining liable for any deficiency.

          SECTION 3.03.  Warranty as to Stock. The Company hereby represents and
warrants that the Stock,  when issued,  will be validly  issued,  fully paid and
nonassessable  and that any  preemptive  rights have been validly  waived.  Such
representation  and  warranty  shall  survive  the  deposit of the Stock and the
issuance of Receipts.

          SECTION  3.04.   Warranty  as  to  Receipts.   The  Depositary  hereby
represents and warrants that the Receipts,  when issued, will be validly issued,
fully paid and nonassessable. Such representation and warranty shall survive the
deposit of the Stock and the issuance of Receipts.

          SECTION 3.05. Covenants and Warranties as to Common Stock. The Company
covenants that it will keep reserved or otherwise  available a sufficient number
of  authorized  and  unissued   shares  of  Common  Stock  to  meet   conversion
requirements in respect of the Stock and that it will give written notice to the
Depositary  of any  adjustments  in the  conversion  price  as set  forth in the
Certificate.  The Company  represents  and warrants that the Common Stock issued
upon conversion of Stock,  when issued,  will be validly issued,  fully paid and
non-assessable.

                                   ARTICLE IV

                        The Deposited Securities; Notices

          SECTION  4.01.  Cash  Distributions.  Whenever  the  Depositary  shall
receive any cash dividend or other cash distribution on the Stock, including any
cash  received  upon  redemption  of the Stock  pursuant  to Section  2.03 or an
Exchange  pursuant to Section 2.10  (subject in each case to the  provisions  of
Section  2.09),  the  Depositary  shall,  subject  to  Sections  3.01 and  3.02,
distribute  to Record  Holders of Receipts on the record date fixed  pursuant to
Section  4.04 such  amounts  of such sum as are,  as nearly as  practicable,  in
proportion  to the  respective  numbers of  Depositary  Shares  evidenced by the
Receipts held by such holders;  provided,  however,  that in case the Company or
the  Depositary  shall be required to withhold and shall  withhold from any cash
dividend or other cash  distribution in respect of the Stock  represented by the
Receipts  held by any  holder an amount on account  of taxes,  the  amount  made
available  for  distribution  or  distributed  in respect of  Depositary  Shares
represented by such Receipts shall be reduced accordingly.

                                      -20-


<PAGE>



The Depositary shall distribute or make available for distribution,  as the case
may be, only such amount,  however, as can be distributed without attributing to
any holder of Depositary  Shares a fraction of one cent,  and any balance not so
distributable  shall be held by the Depositary  (without  liability for interest
thereon)  and shall be added to and be treated as part of the next sum  received
by  the  Depositary  for   distribution  to  Record  Holders  of  Receipts  then
outstanding.

          SECTION  4.02.  Distributions  Other  than  Cash,  Depositary  Shares,
Rights, Preferences or Privileges. Except in the case of real property, whenever
the  Depositary  shall  receive  any  distribution  other than cash,  Depositary
Shares, rights,  preferences or privileges upon the Stock, the Depositary shall,
subject to Sections 3.01 and 3.02,  distribute to Record  Holders of Receipts on
the record date fixed pursuant to Section 4.04 such amounts of the securities or
property  (other  than  real  property)  received  by it as are,  as  nearly  as
practicable,  in  proportion  to the  respective  numbers of  Depositary  Shares
evidenced by the Receipts held by such holders in any manner that the Depositary
may deem equitable and practicable for accomplishing  such  distribution.  If in
the  opinion  of  the  Depositary  after  consultation  with  the  Company  such
distribution cannot be made proportionately among such Record Holders, or if for
any other reason  (including any requirement  that the Company or the Depositary
withhold an amount on account of taxes) the Depositary deems, after consultation
with the Company, such distribution not to be feasible, the Depositary may, with
the  approval  of the  Company,  adopt  such  method as it deems  equitable  and
practicable for the purpose of effecting such  distribution,  including the sale
(at public or private sale) of the securities or property thus received,  or any
part thereof, at such place or places and upon such terms as it may deem proper.
The net proceeds of any such sale shall,  subject to Sections  3.01 and 3.02, be
distributed  or made  available  for  distribution,  as the case may be,  by the
Depositary to Record Holders of Receipts as provided by Section 4.01 in the case
of a distribution  received in cash. The Company shall not make any distribution
of such  securities  unless the Company  shall have  provided the  Depositary an
opinion of counsel stating that such  securities have been registered  under the
Securities Act or do not need to be so registered.

          SECTION 4.03. Subscription Rights,  Preferences or Privileges.  If the
Company  shall at any time offer or cause to be offered to the  persons in whose
names Stock is recorded on the books of the Company any rights,  preferences  or
privileges to subscribe for or to purchase any securities

                                      -21-


<PAGE>



or any rights,  preferences  or  privileges  of any other  nature,  such rights,
preferences  or privileges  shall in each such instance be made available by the
Depositary  to the Record  Holders of Receipts in such manner as the  Depositary
may  determine,  either  by  the  issue  to  such  Record  Holders  of  warrants
representing  such rights,  preferences or privileges or by such other method as
may be deemed  appropriate by the Depositary in its discretion with the approval
of the Company; provided,  however, that (i) if at the time of issue or offer of
any such rights,  preferences or privileges the Depositary determines that it is
not  feasible,  or the Company  determines  that it is not lawful,  to make such
rights,  preferences or privileges available to holders of Receipts by the issue
of warrants or otherwise,  or (ii) if and to the extent so instructed by holders
of  Receipts  who  do  not  desire  to  exercise  such  rights,  preferences  or
privileges,  then  the  Depositary,  in its  discretion  (with  approval  of the
Company, in any case where the Depositary has determined that it is not feasible
to make such rights,  preferences or privileges  available),  may, if applicable
laws  or the  terms  of such  rights,  preferences  or  privileges  permit  such
transfer, sell such rights, preferences or privileges at public or private sale,
at such  place or places  and upon  such  terms as it may deem  proper.  The net
proceeds  of any  such  sale  shall,  subject  to  Sections  3.01 and  3.02,  be
distributed by the Depositary to the Record Holders of Receipts entitled thereto
as provided by Section 4.01 in the case of a distribution received in cash.

          If any action under the laws of any  jurisdiction or any  governmental
or administrative authorization, consent or permit is required in order for such
rights,  preferences  or privileges to be made available to holders of Receipts,
the Company agrees with the Depositary  that the Company will use its reasonable
business  efforts to take such action or obtain such  authorization,  consent or
permit sufficiently in advance of the expiration of such rights,  preferences or
privileges  to enable  such  holders to exercise  such  rights,  preferences  or
privileges.

          SECTION  4.04.  Notice of Dividends,  etc.;  Fixing of Record Date for
Holders of Receipts. Whenever any cash dividend or other cash distribution shall
become payable or any distribution  other than cash shall be made, or if rights,
preferences  or  privileges  shall at any time be offered,  with  respect to the
Stock,  or whenever the  Depositary  shall receive  notice of (i) any meeting at
which holders of the Stock are entitled to vote or of which holders of the Stock
are  entitled  to notice,  or (ii) any  election  on the part of the  Company to
redeem, or issue Exchange Debentures in exchange for, any shares of the Stock

                                      -22-


<PAGE>



or (iii) whenever the Depositary and the Company shall decide it is appropriate,
the Depositary shall in each such instance fix a record date (which shall be the
same date as the record date fixed by the Company with respect to the Stock) for
the  determination  of the holders of Receipts  who shall be entitled to receive
such  dividend,  distribution,  rights,  preferences  or  privileges  or the net
proceeds of sales thereof,  or to give  instructions  for the exercise of voting
rights at any such  meeting,  or who shall be entitled to notice of such meeting
or for any other  reasons  which  the  Company  and the  Depositary  shall  deem
appropriate.

          SECTION 4.05. Voting Rights.  Upon receipt of notice of any meeting at
which the holders of Stock are entitled to vote, the Depositary  shall,  as soon
as practicable thereafter, mail to the Record Holders of Receipts a notice which
shall contain (i) such information as is contained in such notice of meeting and
(ii) a  statement  that the  holders of Receipts at the close of business on the
relevant record date may, subject to any applicable  restrictions,  instruct the
Depositary as to the exercise of the voting  rights  pertaining to the amount of
Stock  represented by their respective  Depositary  Shares (including an express
indication  that  instructions  may  be  given  to  the  Depositary  to  give  a
discretionary  proxy to a person  designated  by the  Company) and (iii) a brief
statement  as to the manner in which such  instructions  may be given.  Upon the
written  request of the holders of Receipts on the  relevant  record  date,  the
Depositary  shall vote or cause to be voted, in accordance with the instructions
set forth in such requests, the maximum number of shares of Stock represented by
the  Depositary  Shares  evidenced  by all  Receipts as to which any  particular
voting  instructions are received.  The Company hereby agrees to take all action
which  may be  deemed  necessary  by the  Depositary  in  order  to  enable  the
Depositary to vote such Stock or cause such Stock to be voted. In the absence of
specific  instructions from the holder of a Receipt, the Depositary will abstain
from voting  (but,  at its  discretion,  not from  appearing at any meeting with
respect to such Stock unless  directed to the contrary by the holders of all the
Receipts)  to the  extent  of the Stock  represented  by the  Depositary  Shares
evidenced by such Receipt.

          Holders  of  Receipts  shall  also be  entitled  to  vote  on  certain
amendments to the Deposit Agreement pursuant to Section 6.01 hereof.

          SECTION   4.06.   Changes   Affecting    Deposited    Securities   and
Reclassifications,  Recapitalization,  etc.  Upon any  change  in par or  stated
value, split-up,

                                      -23-



<PAGE>



combination  or  any  other   reclassification   of  the  Stock,   or  upon  any
recapitalization,  reorganization, merger, amalgamation or consolidation or sale
of all or substantially  all of the Company's assets affecting the Company or to
which it is a party, the Depositary shall, upon the instructions of the Company,
and in  such  manner  as the  Depositary  may  deem  equitable,  (i)  make  such
adjustments  as are  certified by the Company in (x) the fraction of an interest
represented  by one  Depositary  Share in one share of Stock or (y) the ratio of
the redemption  price per Depositary Share to the redemption price of a share of
Stock,  in each case as may be  necessary  fully to reflect  the effects of such
change in par or stated value,  split-up,  combination or other reclassification
of Stock, or of such recapitalization,  reorganization,  merger, amalgamation or
consolidation  and (ii) treat any  securities  which  shall be  received  by the
Depositary  in exchange for or upon  conversion of or in respect of the Stock as
new deposited  securities  so received in exchange for or upon  conversion or in
respect of such Stock.  In any such case the Depositary  may in its  discretion,
with the approval of the Company,  execute and deliver additional  Receipts,  or
may call for the surrender of all  outstanding  Receipts to be exchanged for new
Receipts specifically describing such new deposited securities.

          SECTION 4.07.  Inspection of Reports.  The  Depositary  shall,  during
normal business hours and upon reasonable notice,  make available for inspection
by holders of Receipts at the Depositary's  Office,  and at such other places as
it may from time to time deem advisable, any reports and communications received
from the Company which are received by the Depositary as the holder of Stock and
made generally available to the holders of Stock.

          SECTION  4.08.  Lists of Receipt  Holders.  Promptly upon request from
time to time by the Company,  the Depositary shall furnish to it a list, as of a
recent date, of the names,  addresses  and holdings of Depositary  Shares of all
persons in whose names Receipts are registered on the books of the Depositary.

          SECTION 4.09. Withholding. Notwithstanding any other provision of this
Deposit  Agreement,  in the  event  that  the  Depositary  determines  that  any
distribution  of  securities  or other  property is subject to any tax which the
Depositary  is  obligated to withhold,  the  Depositary  may dispose of all or a
portion of such  securities or other property in such amounts and in such manner
as the Depositary  deems  necessary and practicable to pay such taxes, by public
or private sale, and the Depositary shall

                                      -24-


<PAGE>



distribute  the net  proceeds  of any  such  sale  or the  balance  of any  such
securities  or other  property  after  deduction of such taxes to the Holders of
Receipts  entitled thereto in proportion to the number of Depositary Shares held
by them respectively.

                                    ARTICLE V

                        The Depositary, the Depositary's
                      Agents, the Registrar and the Company

          SECTION 5.01.  Maintenance of Offices,  Agencies and Transfer Books by
the  Depositary;  Registrar.  Upon  execution  of this  Deposit  Agreement,  the
Depositary  shall  maintain  at the  Depositary's  Office,  facilities  for  the
execution and delivery, registration and registration of transfer, surrender and
exchange of Receipts,  and at the offices of the  Depositary's  Agents,  if any,
facilities for the delivery, registration of transfer, surrender and exchange of
Receipts, all in accordance with the provisions of this Deposit Agreement.

          The Depositary shall keep books at the Depositary's Office which shall
reflect  registration  and  registration of transfer of Receipts,  split-ups and
combinations  and  conversions  of  Depositary  Shares  and  which  books at all
reasonable times shall be open for inspection by the Record Holders of Receipts;
provided,  that any such holder  requesting to exercise such right shall certify
to the Depositary that such inspection shall be for a proper purpose  reasonably
related to such person's  interest as an owner of Depositary Shares evidenced by
the Receipts.

          The  Depositary  may  close  such  books  only  when the  register  of
stockholders of the Company is closed.

          The  Depositary  may,  with the  approval  of the  Company,  appoint a
Registrar for  registration of the Receipts or the Depositary  Shares  evidenced
thereby.  Such  Registrar  (which may be the  Depositary  if so permitted by the
requirements  of  such  Exchange)  may be  removed  and a  substitute  Registrar

the Depositary's  Agents,  the Registrar or the Company.  Neither the Depositary

any  other  governmental  authority  or,  in the  case  of the  Depositary,  the
Depositary's  Agent or the  Registrar,  by reason of any  provision,  present or
future, of the Company's Restated Certificate of Incorporation,  as from time to
time amended (including the Certificate),  or by reason of any act of God or war
or other circumstance  beyond the control of the relevant party, the Depositary,
the  Depositary's  Agent,  the  Registrar  or the Company  shall be prevented or
forbidden  from,  or subjected to any penalty on account of, doing or performing
any act or thing which the terms of this Deposit Agreement provide shall be done
or performed; nor shall the Depositary, any Depositary's Agent, any Registrar or
the  Company  incur  liability  to any holder of a Receipt  (i) by reason of any
nonperformance or delay,  caused as aforesaid,  in the performance of any act or
thing which the terms of this Deposit  Agreement provide shall or may be done or
performed,  or (ii) by reason of any exercise  of, or failure to  exercise,  any
discretion  provided for in this Deposit  Agreement  except,  in the case of any
such  exercise or failure to exercise  discretion  not caused as  aforesaid,  if
caused by the gross  negligence or willful  misconduct of the party charged with
such exercise or failure to exercise.

          SECTION 5.03.  Obligations of the Depositary,  the Depositary's Agents
and the Registrar.  Neither the Depositary  nor any  Depositary's  Agent nor any
Registrar  nor the  Company  assumes any  obligation  or shall be subject to any
liability under this Deposit Agreement to holders of Receipts other than for its
gross negligence or willful misconduct.

          Neither the  Depositary nor any  Depositary's  Agent nor any Registrar
nor the Company shall be under any obligation to appear in,  prosecute or defend
any action,  suit or other  proceeding in respect of the Stock,  the  Depositary
Shares or the  Receipts  which in its  opinion  may  involve  it in  expense  or
liability unless indemnity  satisfactory to it against all expense and liability
be furnished as often as may be required.

          Neither the  Depositary nor any  Depositary's  Agent nor any Registrar
nor the  Company  shall be liable for any action or any  failure to act by it in
reliance upon the written advice of legal counsel or accountants, or information
from any person  presenting  Stock for  deposit,  any holder of a Receipt or any
other  person  believed  by it in  good  faith  to be  competent  to  give  such
information. The Depositary and any Depositary's Agent and any Registrar and the
Company  may each rely and shall each be  protected  in acting  upon any written
notice, request, direction or other

                                      -26-

document  believed by it to be genuine and to have been signed or  presented  by
the proper party or parties.

          The Depositary  shall not be responsible  for any failure to carry out
any  instruction  to vote any of the shares of Stock or for the manner or effect
of any such vote made, as long as any such action or non-action is in good faith
and  does  not  result  from  gross  negligence  or  willful  misconduct  of the
Depositary.  The Depositary  undertakes,  and any Registrar shall be required to
undertake,  to perform such duties and only such duties as are  specifically set
forth in this Deposit  Agreement,  and no implied covenants or obligations shall
be read into this Deposit Agreement against the Depositary or any Registrar. The
Depositary  will indemnify the Company against any liability which may arise out
of acts performed or omitted by the Depositary or the Depositary's Agents due to
its or their gross  negligence or bad faith.  The Depositary,  the  Depositary's
Agents,  and any  Registrar  may own and deal in any class of  securities of the
Company and its  affiliates  and in  Receipts.  The  Depositary  may also act as
transfer  agent or  registrar  of any of the  securities  of the Company and its
affiliates.

          SECTION 5.04.  Resignation and Removal of the Depositary;  Appointment
of Successor  Depositary.  The  Depositary  may at any time resign as Depositary
hereunder by notice of its  election so to be  delivered  to the  Company,  such
resignation to take effect upon the  appointment  of a successor  Depositary and
its acceptance of such appointment as hereinafter provided.

          The  Depositary may at any time be removed by the Company by notice of
such removal  delivered to the Depositary,  such removal to take effect upon the
appointment of a successor  Depositary and its acceptance of such appointment as
hereinafter provided.

          In case at any time the Depositary acting hereunder shall resign or be
removed prior to the termination of this Deposit  Agreement,  the Company shall,
within 60 days after the delivery of the notice of  resignation  or removal,  as
the case may be, appoint a successor Depositary,  which shall be a bank or trust
company having its principal office in the United States of America and having a
combined capital and surplus of at least $50,000,000. If no successor Depositary
shall have been so appointed and have accepted  appointment within 60 days after
delivery  of such  notice,  the  resigning  or removed  Depositary  may,  at the
Company's  expense,  petition  any  court  of  competent  jurisdiction  for  the
appointment of a successor Depositary.  Every successor Depositary shall execute
and

                                      -27-


<PAGE>



deliver to its predecessor and to the Company an instrument in writing accepting
its appointment hereunder, and thereupon such successor Depositary,  without any
further act or deed,  shall  become  fully  vested with all the rights,  powers,
duties and  obligations  of its  predecessor  and for all purposes  shall be the
Depositary under this Deposit Agreement,  and such predecessor,  upon payment of
all sums due it and on the written  request of the  Company,  shall  execute and
deliver an instrument  transferring  to such  successor all rights and powers of
such predecessor hereunder,  shall duly assign,  transfer and deliver all right,
title and  interest in the Stock and any moneys or property  held  hereunder  to
such successor, and shall deliver to such successor a list of the Record Holders
of all outstanding Receipts. Any successor Depositary shall promptly mail notice
of its appointment to the Record Holders of Receipts.

            Any corporation into or with which the Depositary may be
merged,  consolidated  or converted  shall be the  successor of such  Depositary
without the  execution  or filing of any document or any further act, and notice
thereof  shall  not  be  required  hereunder.   Such  successor  Depositary  may
authenticate  the Receipts in the name of the  predecessor  Depositary or in the
name of the successor Depositary.

          SECTION 5.05.  Corporate Notices and Reports.  The Company agrees that
it will  transmit  to the  Record  Holders  of  Receipts,  in  each  case at the
addresses  furnished  to it  pursuant to Section  4.08,  all notices and reports
(includ ing, without limitation,  financial  statements) required by law, by the
rules of any national  securities  exchange upon which the Stock, the Depositary
Shares or the Receipts are listed or by the Company's  Restated  Certificate  of
Incorporation,  as from time to time amended (including the Certificate),  to be
furnished by the Company to holders of Stock.  Such  transmission will be at the
Company's expense.  At any time when the Company is not subject to Section 13 or
15(d) of the  Securities  Exchange  Act of 1934,  as amended,  the Company  will
promptly  furnish or cause to be furnished,  upon request of holders of Receipts
and prospective purchasers of Depositary Shares, to such holders and prospective
purchasers,  copies of the  information  required to be delivered to holders and
prospective  purchasers of such securities pursuant to Rule 144A(d)(4) under the
Securities  Act  (or  any  successor  provision  thereto)  in  order  to  permit
compliance  with Rule 144A in  connection  with  resales by such holders of such
securities.  The Company will pay the expenses of printing and  distributing  to
such holders and prospective purchasers all such documents.

          SECTION  5.06.  Indemnification  by the  Company.  The  Company  shall
indemnify the Depositary,  any Depositary's Agent and any Registrar against, and
hold each of them harmless from, loss, liability or expense (including the costs
and  expenses of  defending  itself)  which may arise out of acts  performed  or
omitted in connection with this Deposit Agreement,  as amended,  supplemented or
modified  from  time  to  time,  and the  Receipts  (i) by the  Depositary,  any
Registrar or any of their respective agents (including any Depositary's  Agent),
except for any liability arising out of gross negligence,  willful misconduct or
bad faith on the respective parts of any such person or persons,  or (ii) by the
Company or any of its  agents,  or (b) the offer,  sale or  registration  of the
Receipts or the Stock pursuant to the provisions  hereof. The obligations of the
Company  set forth in this  Section  5.06 shall  survive any  succession  of any
Depositary, Registrar or Depositary's Agent. The costs and expenses of enforcing
this right of indemnification shall also be paid by the Company.

          SECTION 5.07. Taxes or Other Governmental  Charges.  The Company shall
pay all transfer and other taxes and  governmental  charges  arising solely from
the existence of the depositary arrangements.  The Company shall pay all charges
of the  Depositary in connection  with the initial  deposit of the Stock and the
initial issuance of the Depositary Shares, redemption of the Stock at the option
of the  Company  and all  withdrawals  of  shares  of the  Stock  by  owners  of
Depositary Shares.  All other transfer and other taxes and governmental  charges
shall be at the expense of holders of Depositary Shares. If a holder of Receipts
requests  the  Depositary  to perform  duties not  required  under this  Deposit
Agreement,  the  Depositary  shall  notify  the  holder  of  the  cost  of  this
performance  of such  duties.  Such  holder  will be liable for the  charges and
expenses  related to such  performance.  All other  charges and  expenses of the
Depositary and any Depositary's Agent hereunder and of any Registrar (including,
in each case, fees and expenses of counsel) incident to the performance of their
respective  obligations  hereunder will be paid upon  consultation and agreement
between  the  Depositary  and the  Company  as to the  amount and nature of such
charges and expenses (except those expenses  pursuant to the second paragraph of
Section 2.05 and Section 2.09,  which  expenses shall be paid by such holders of
the Depositary  Shares).  The Depositary shall present its statement for charges
and expenses to the Company  once every three months or at such other  intervals
as the  Company and the  Depositary  may agree.  The  Company  agrees to pay (or
reimburse  the  Depositary)  for all  reasonable  costs  with  regard to mailing
notices to holders.

                            Amendment and Termination

          SECTION 6.01.  Amendment.  The form of the Receipts and any provisions
of this  Deposit  Agreement  may at any time and from time to time be amended by
agreement  between the Company and the  Depositary in any respect which they may
deem necessary or desirable; provided, however, that no such amendment which (i)
shall  adversely  alter the rights of the  holders of  Receipts or (ii) would be
inconsistent  with the rights granted to the holder of the Stock pursuant to the
Purchase  Agreement or the Certificate  shall be effective unless such amendment
shall have been approved by the holders of at least a majority of the Depositary
Shares then outstanding.  Every holder of an outstanding Receipt at the time any
such amendment  becomes  effective  shall be deemed,  by continuing to hold such
Receipt,  to consent and agree to such  amendment and to be bound by the Deposit
Agreement as amended thereby.

          SECTION 6.02. Termination. This Deposit Agreement may be terminated by
the Company or the Depositary only after (i) all outstanding  Depositary  Shares
shall have been  redeemed  pursuant  to Section  2.03 or  exchanged  pursuant to
Section 2.10, (ii) there shall have been made a final distribution in respect of
the Stock in connection with any  liquidation,  dissolution or winding up of the
Company  and such  distribution  shall have been  distributed  to the holders of
Depositary  Shares  pursuant to Section 4.01 or 4.02, as applicable,  (iii) upon
consent of holders of  Receipts  representing  not less than  two-thirds  of the
Depositary Shares then outstanding or (iv) the Company shall have exchanged each
share of  Stock  for  shares  of  Common  Stock or  shall  have  exchanged  each
Depository Share for Exchange Debentures.

          Whenever the Deposit  Agreement has been terminated  pursuant to (iii)
above, the Depositary will mail notice of such termination to the Record Holders
of all Depositary  Shares then outstanding at least 30 days and not more than 60
days  prior to the date  fixed in that  notice for  termination  of the  Deposit
Agreement.  If any  Depositary  Shares  remain  outstanding  after  the  date of
termination,   the  Depositary  thereafter  will  discontinue  the  transfer  of
Depositary  Shares,  will  suspend the  distribution  of dividends to the owners
thereof,  and will not give any  further  notices  (other  than  notice  of such
termination)  or perform any further acts under this Deposit  Agreement,  except
that the Depositary will continue (i) to collect  dividends on the Stock and any
other distributions with

                                      -30-

<PAGE>



respect  thereto,  (ii) to  deliver  or cause to be  delivered  shares of Stock,
together with such dividends and distributions,  or principal and interest,  and
the net  proceeds  of any  sales of  rights,  preferences,  privileges  or other
property   (other  than  real  property)  in  exchange  for  Depositary   Shares
surrendered.  At any time  after the  expiration  of two years  from the date of
termination,  the  Depositary  may sell the  Stock  then held by it at public or
private sale, at such place or places and upon such terms as it deems proper and
may  thereafter  hold the net proceeds of any such sale,  without  liability for
interest,  for the pro rata benefit of the owners of the Depositary Shares which
have not theretofore been surrendered.  Subject to applicable  escheat laws, any
monies set aside by the  Company in respect of any payment  with  respect to the
Stock represented by the Depositary Shares, or dividends thereon,  and unclaimed
at the end of two years from the date upon which such payment is due and payable
shall revert to the general  funds of the  Company,  after which  reversion  the
holders of such  Depositary  Shares shall look only to the general  funds of the
Company for the payment thereof.

          Upon the termination of this Deposit  Agreement,  the Company shall be
discharged  from all  obligations  under this Deposit  Agreement  except for its
obligations to the Depositary,  any  Depositary's  Agent and any Registrar under
Sections 5.06 and 5.07.

                                  Miscellaneous

          SECTION 7.01. Counterparts.  This Deposit Agreement may be executed in
any  number of  counterparts,  and by each of the  parties  hereto  on  separate
counterparts,  each of which counterparts, when so executed and delivered, shall
be deemed an original, but all such counterparts taken together shall constitute
one and the same instrument.

          SECTION 7.02. Exclusive Benefit of Parties.  This Deposit Agreement is
for the exclusive  benefit of the parties  hereto,  including the holders of the
Receipts, and their respective successors hereunder,  and shall not be deemed to
give  any  legal or  equitable  right,  remedy  or  claim  to any  other  person
whatsoever.

been duly given if personally  delivered or sent by mail or by telegram or telex
confirmed  by letter,  addressed  to such  Record  Holder at the address of such
Record  Holder as it appears on the books of the  Depositary,  or if such holder
shall have filed with the Depositary a written request that notices intended for
such holder be mailed to some other address,  at the address  designated in such
request.

          Delivery  of a notice  sent by mail or by  telegram  or telex shall be
deemed to be effected at the time when a duly  addressed  letter  containing the
same (or a  confirmation  thereof in the case of a telegram or telex message) is
deposited,  postage prepaid,  in a post office letter box. The Depositary or the
Company may, however, act upon any telegram or telex message received by it from
the other or from any holder of a Receipt, notwithstanding that such telegram or
telex message shall not subsequently be confirmed by letter or as aforesaid.

          SECTION 7.05.  Depositary's  Agents.  The  Depositary may from time to
time appoint  Depositary's  Agents to act in any respect for the  Depositary for
the purposes of this Deposit  Agreement  and may at any time appoint  additional
Depositary's Agents and vary or terminate the

                                      -32-

from time to time shall be parties to this Deposit  Agreement and shall be bound
by and be entitled to the benefit of all of the terms and conditions  hereof and
of the  Receipts by  acceptance  of delivery  thereof  without the  necessity of
executing a counterpart hereof.

          SECTION 7.07.  Governing Law. This Deposit  Agreement and the Receipts
and all rights hereunder and thereunder and provisions  hereof and thereof shall
be governed by, and construed in accordance  with,  the laws of the State of New
York without regard to principles of conflict of laws.

                            PREFERENCES AND RIGHTS OF

                       AMERICAN RADIO SYSTEMS CORPORATION

                   7% CONVERTIBLE EXCHANGEABLE PREFERRED STOCK


          American   Radio   Systems   Corporation,   a   Delaware   corporation
(hereinafter called, the "Corporation"),  pursuant to Section 151 of the General
Corporation Law of the State of Delaware,  does hereby make this  Certificate of
Designation  and does hereby  state and certify that  pursuant to the  authority
expressly  vested in the Board of Directors of the  Corporation  by the Restated
Certificate of Incorporation  of the Corporation  (the "Restated  Certificate"),
the Board of Directors of the Corporation duly adopted the following resolution:

          RESOLVED,  that  pursuant to Article Four of the Restated  Certificate
(which  authorizes  1,000,000  shares of preferred stock,  $.01 par value),  the
Board  of  Directors  of  the  Corporation   hereby  fixes  the  voting  powers,
designations  and  preferences,  and the relative,  participating,  optional and
other special  rights,  and the  qualifications,  limitations  and  restrictions
thereof, of a series of Convertible Exchangeable Preferred Stock.

          RESOLVED,  that each share of the Convertible  Exchangeable  Preferred
Stock shall rank equally in all  respects and shall be subject to the  following
provisions:

          SECTION 1. Designation;  Rank. This series of Preferred Stock shall be
designated 7% Convertible Exchangeable Preferred Stock, par value $.01 per share
(the "Convertible  Preferred Stock"). The Convertible Preferred Stock will rank,
with  respect  to  dividend  rights and rights on  liquidation,  winding-up  and
dissolution, (i) senior to all classes of Common Stock of the Corporation,  each
other class of capital stock or series of preferred stock  established after the
date  hereof by the Board of  Directors  of the  Corporation  (or, to the extent
permitted by the General Corporation Law of the State of Delaware, the Executive
Committee  thereof) (the "Board") which does not expressly provide that it ranks
senior to or on a parity  with the  Convertible  Preferred  Stock as to dividend
rights and  rights on  liquidation,  winding-up  and  dissolution  (collectively
referred to with the Common Stock of the  Corporation  as "Junior  Securities");
(ii) on a parity with each other class of capital stock or series of preferred

                                      



<PAGE>



stock issued by the Corporation  established after the date hereof by the Board,
which  expressly  provides  that  such  series  will  rank on a parity  with the
Convertible  Preferred  Stock as to dividend  rights and rights on  liquidation,
winding-up and dissolution  (collectively  referred to as "Parity  Securities");
and (iii)  junior to each other  class of capital  stock or series of  preferred
stock  established  after  the  date  hereof  by the  Board  the  terms of which
specifically  provide  that  such  series  will rank  senior to the  Convertible
Preferred Stock as to dividend rights and rights on liquidation,  winding-up and
dissolution (collectively referred to as "Senior Securities").

          SECTION 2. Authorized  Number.  The number of shares  constituting the
Convertible Preferred Stock shall be 137,500 shares.

          SECTION 3. Dividends.  Holders of shares of the Convertible  Preferred
Stock will be entitled to receive,  when, as and if declared by the Board out of
funds of the  Corporation  legally  available for payment,  cash dividends at an
annual rate of 7%, payable  quarterly in arrears on March 31, June 30, September
30 and December 31 of each year,  commencing  September 30, 1996.  Each dividend
will be payable to holders of record as they appear on the stock  transfer books
of the  Corporation  on a record  date,  not more  than 60 nor less than 10 days
before the payment date,  fixed by the Board.  Dividends will be cumulative from
the date of original  issuance of the  Convertible  Preferred  Stock.  Dividends
payable on the Convertible Preferred Stock for each full dividend period will be
computed by  annualizing  the  dividend  rate and  dividing  by four.  Dividends
payable for any period less than a full dividend  period will be computed on the
basis of a 360-day year  consisting of twelve  30-day  months.  The  Convertible
Preferred  Stock will not be entitled to any dividend,  whether payable in cash,
property or stock, in excess of full cumulative  dividends.  No interest, or sum
of money in lieu of  interest,  will be payable in  respect of any  accrued  and
unpaid dividends.

          No full  dividends  may be declared or paid or funds set apart for the
payment  of  dividends  on any Parity  Securities  for any  period  unless  full
cumulative  dividends  shall have been paid or set apart for such payment on the
Convertible  Preferred Stock. If full dividends are not so paid, the Convertible
Preferred  Stock shall share dividends pro rata with the Parity  Securities.  No
dividends may be paid or set apart for such payment on Junior Securities (except
dividends on Junior Securities in additional shares of Junior Securities) and no
Junior  Securities  may be  repurchased,  redeemed or otherwise  retired nor may
funds be

                                       -2-


<PAGE>



set apart for payment with respect thereto, if full dividends have not been paid
on the Convertible Preferred Stock.

          SECTION  4.  Liquidation  Rights.  In the  event of any  voluntary  or
involuntary  liquidation,  dissolution or winding up of the Corporation,  before
any  payment  or  distribution  of  assets  is  made on any  Junior  Securities,
including,  without limitation,  Common Stock of the Corporation, the holders of
Convertible Preferred Stock shall receive a liquidation preference of $1,000 per
share and shall be entitled to receive an amount equal to all accrued and unpaid
dividends  through  the date of  distribution,  and the  holders  of any  Parity
Securities  shall be entitled to receive an amount equal to the full  respective
liquidation  preferences  (including any premium) to which they are entitled and
shall receive an amount equal to all accrued and unpaid  dividends  with respect
to their respective  shares through and including the date of distribution.  If,
upon such a voluntary or involuntary  liquidation,  dissolution or winding up of
the  Corporation,  the assets of the Corporation are insufficient to pay in full
the amounts described above as payable with respect to the Convertible Preferred
Stock and any Parity Securities,  the holders of the Convertible Preferred Stock
and such Parity Securities will share ratably in any such distribution of assets
of  the  Corporation  first  in  proportion  to  their  respective   liquidation
preferences  until such  preferences are paid in full, and then in proportion to
their respective  amounts of accrued but unpaid dividends.  After payment of any
such  liquidation  preference and accrued  dividends,  the shares of Convertible
Preferred  Stock  will  not be  entitled  to any  further  participation  in any
distribution of assets by the  Corporation.  Neither the sale or transfer of all
or  substantially  all  the  assets  of  the  Corporation,  nor  the  merger  or
consolidation  of the  Corporation  into or with any other  corporation or other
entity or a merger of any other  corporation  or other  entity  with or into the
Corporation,  will be deemed to be a  liquidation,  dissolution or winding up of
the Corporation.

          SECTION 5. Voting Rights.  (a) In addition to such other vote, if any,
as may be required by Delaware  law or provided by the  resolution  creating any
other  series of  preferred  stock to the extent such  resolution  refers to the
Convertible  Preferred  Stock,  so long as any shares of  Convertible  Preferred
Stock are  outstanding,  the vote or consent of the holders of a majority of the
outstanding  shares of Convertible  Preferred  Stock and any Parity  Securities,
voting  together as a single class (with each share being entitled to the number
of votes otherwise

                                       -3-


<PAGE>



specified, if so specified, for such securities) without regard to series, shall
be necessary to (i) issue,  authorize or increase the  authorized  amount of, or
issue, authorize or increase the authorized amount of any obligation or security
convertible  into or  evidencing  a right to  purchase,  any  class or series of
Senior  Securities,  (ii)  increase or  decrease  the par value of the shares of
Convertible Preferred Stock or (iii) alter or change the powers, preferences, or
special rights of the shares of Convertible Preferred Stock so as to affect them
adversely.

          (b) Prior to the Debenture  Exchange Date (as defined in Section 10(a)
below),  the Corporation  shall not amend or modify the Indenture (as defined in
Section 10(a) below),  without the affirmative  vote or consent of holders of at
least a majority  of the  outstanding  shares of  Convertible  Preferred  Stock,
voting together as a single class;  provided,  however, that the Corporation and
the Trustee (as defined in Section 10(a) below) shall be permitted,  without any
vote or consent of such holders,  to effect any amendments to the Indenture that
could have been effected  under the Indenture  without the consent of holders of
Exchange  Debentures  (as  defined  in  Section  10(a)  below)  if any  Exchange
Debentures were then outstanding.

          (c) (i) In the  event  that  dividends  on the  Convertible  Preferred
Stock, if any are then outstanding,  remain unpaid in cash in an amount equal to
six full quarterly dividends,  the maximum authorized number of directors of the
Corporation will be increased by two and holders of Convertible  Preferred Stock
shall be entitled to vote their shares of Convertible  Preferred Stock, together
with the holders of any Parity  Securities  upon which like  voting  rights have
been conferred and are exercisable,  in accordance with the procedures set forth
below,  to elect, as a class,  an additional two directors;  provided,  however,
that (x) holders of Convertible Preferred Stock and such Parity Securities shall
not  elect  as  director  any  individual  who if so  elected  would  cause  the
Corporation to be in violation of the Communications Act of 1934, as amended, or
the rules and regulations of the Federal Communications  Commission (the "FCC"),
and  (y) if the  exercise  of  such  right  by the  holders  of the  Convertible
Preferred Stock and such Parity Securities would cause the Corporation or any of
its  subsidiaries  not to  qualify  for a  license  granted  by the FCC  that is
necessary for the continued  operation of the Corporation or such  subsidiaries,
the Board shall be  increased,  and such holders shall be entitled to vote their
shares to elect only such lesser number,  including  zero, of directors as would
not result in the  Corporation  or such  subsidiaries  not  qualifying  for such
license. So long as

                                       -4-


<PAGE>



any shares of Convertible  Preferred Stock shall be outstanding,  the holders of
Convertible  Preferred Stock shall retain the right to vote and elect,  with the
holders of any such Parity  Securities,  voting together as a single class (with
each share being  entitled to the number of votes  otherwise  specified for such
securities)  without  regard  to  series,  such  number of  directors  until all
dividends on the Convertible  Preferred Stock, if any are then outstanding,  are
paid in full or declared and set aside for payment.  Such period is  hereinafter
referred to as a "default period".

          (ii) So long as any shares of  Convertible  Preferred  Stock  shall be
outstanding,  during any default  period,  such  voting  right of the holders of
Convertible  Preferred  Stock may be exercised  initially  at a special  meeting
called  pursuant  to  subparagraph  (iii)  below  or at any  annual  meeting  of
stockholders.  The  absence of a quorum of holders of Common  Stock or any class
thereof  shall not affect the  exercise of such voting  rights by the holders of
Convertible Preferred Stock and Parity Securities.

          (iii)  Unless the holders of  Convertible  Preferred  Stock and Parity
Securities so entitled,  if any are then  outstanding,  have, during an existing
default period,  previously exercised their right to elect directors,  the Board
may order, or any  stockholder or stockholders  owning in the aggregate not less
than 5% of the outstanding shares of Convertible Preferred Stock and such Parity
Securities,  taken  together as a single  class,  may request,  the calling of a
special  meeting of  holders  of  Convertible  Preferred  Stock and such  Parity
Securities, if any are then outstanding, which meeting shall thereupon be called
by the Chairman of the Board,  the President,  a Vice President or the Secretary
of the  Corporation.  Notice of such meeting and of any annual  meeting at which
holders of Convertible  Preferred Stock and such Parity  Securities are entitled
to vote  pursuant to this  paragraph  shall be given to each holder of record of
Convertible  Preferred  Stock by mailing a copy of such notice to such holder at
such  holder's last address as the same appears on the stock  transfer  books of
the  Corporation.  Such meeting shall be called for a time not later than twenty
(20) days  after such order or  request,  or, in default of the  calling of such
meeting  may be called on  similar  notice by any  stockholder  or  stockholders
owning  in  the  aggregate  not  less  than  5% of  the  outstanding  shares  of
Convertible  Preferred  Stock and such Parity  Securities,  taken  together as a
single class.  Notwithstanding the provisions of this paragraph, no such special
meeting shall be called during the period within ninety (90) days

                                       -5-


<PAGE>



immediately preceding the date fixed for the next annual
meeting of stockholders.

          (iv) During any  default  period,  the holders of Common  Stock of the
Corporation, and other classes of stock of the Corporation, if applicable, shall
continue  to be  entitled  to elect all of the  directors  unless  and until the
holders of Convertible  Preferred Stock and Parity  Securities so entitled shall
have exercised their right to elect two directors  voting as a class,  after the
exercise  of  which  right  (x) the  directors  so  elected  by the  holders  of
Convertible  Preferred Stock and such Parity Securities shall continue in office
until the earlier of (A) such time as their  successors  shall have been elected
by such holders or (B) the expiration of the default period, and (y) any vacancy
in the Board may be filled by vote of the remaining  director or  directors,  if
any,  theretofore  elected by the holders of the class or classes of stock which
elected the director whose office shall have become  vacant.  References in this
paragraph to directors  elected by the holders of a particular  class or classes
of stock shall include  directors  elected by such director or directors to fill
vacancies as provided in clause (y) of the foregoing sentence.

          (v) Immediately upon the expiration of a default period, (x) the right
of the holders of Convertible  Preferred  Stock to elect  directors shall cease,
(y) the term of office of any  directors  elected by the holders of  Convertible
Preferred Stock and such Parity  Securities as a class shall terminate,  and (z)
the  number of  directors  shall be such  number as may be  provided  for in the
Restated  Certificate or bylaws of the Corporation  irrespective of any increase
made pursuant to the  provisions of  subparagraph  (i) of this  paragraph  (such
number being subject,  however,  to change  thereafter in any manner provided by
law or in the Restated Certificate or bylaws of the Corporation).

          SECTION 6. Conversion.

          (a) Right to Convert.  Each share of Convertible  Preferred Stock will
be  convertible at any time at the option of the holder thereof into such number
of whole  shares of Class A Common  Stock,  par  value  $.01 per  share,  of the
Corporation  (the  "Class  A  Common  Stock")  as  is  equal  to  the  aggregate
liquidation  preference of the shares of Convertible Preferred Stock surrendered
for conversion  divided by the  conversion  price of $42.50 per share of Class A
Common Stock, subject to adjustment as described below (the "Conversion Price").
Holders of  Convertible  Preferred  Stock will not be entitled to any payment or
adjustment on account of accrued and unpaid dividends upon conversion of

                                       -6-


<PAGE>



the  Convertible   Preferred  Stock.  Shares  of  Convertible   Preferred  Stock
surrendered for conversion  during the period after any dividend  payment record
date and prior to the  corresponding  dividend  payment date (unless such shares
shall have been called for redemption on a redemption date within such period or
on such dividend payment date) must be accompanied by payment of an amount equal
to the dividend payable on such shares on such dividend payment date.  Shares of
Convertible  Preferred Stock called for redemption will not be convertible after
the  close  of  business  on the  business  day  preceding  the date  fixed  for
redemption,  unless the Corporation defaults in payment of the redemption price.
No  fractional  shares  of Class A Common  Stock  will be  issued as a result of
conversion,  but in lieu  thereof,  an amount equal to the fair market value (as
determined  by the Board,  whose good faith  determination  shall be  conclusive
evidence of such fair market value, and described in a board resolution) of such
fractional  interest will be paid in cash by the Corporation,  unless payment in
cash is prohibited by the terms of the Corporation's indebtedness, in which case
fractional  shares will be issued or, at the sole discretion of the Corporation,
such fractional shares will be rounded up to the nearest full share.

         (b)  Anti-dilution  Provisions.  The  Conversion  Price is  subject  to
adjustment from time to time as follows:

          (i) In  case  the  Corporation  shall  (1)  pay a  dividend  or make a
     distribution on Class A Common Stock in shares of Class A Common Stock, (2)
     subdivide  its  outstanding  shares of Class A Common  Stock into a greater
     number of shares or (3)  combine its  outstanding  shares of Class A Common
     Stock  into a smaller  number of  shares,  the  Conversion  Price in effect
     immediately  prior to such action  shall be  adjusted as provided  below so
     that the holder of any Convertible  Preferred Stock thereafter  surrendered
     for conversion shall be entitled to receive the number of shares of Class A
     Common  Stock  which  such  holder  would  have been  entitled  to  receive
     immediately   following  such  action  had  such  security  been  converted
     immediately prior thereto. An adjustment made pursuant to this subparagraph
     (i) shall become effective immediately,  except as provided in subparagraph
     (v) below,  after the record date in the case of a dividend or distribution
     and shall become effective immediately after the effective date in the case
     of a subdivision or combination.

          (ii) Except as otherwise  provided in subparagraph (vi) below, in case
     the Corporation  shall issue rights,  warrants or options to all holders of
     Class A Common

                                       -7-

<PAGE>



     Stockentitling  them (for a period  expiring  within  forty-five  (45) days
     after the record date  therefor)  to  subscribe  for or purchase  shares of
     Class A Common  Stock at a price per share  less  than the  Current  Market
     Price per share (as  defined  in  subparagraph  (iv)  below) of the Class A
     Common Stock on the record date mentioned below, the Conversion Price shall
     be adjusted to a price,  computed  to the  nearest  cent,  so that the same
     shall equal the price determined by multiplying:

                    (1) the Conversion Price in effect  immediately prior to the
               date of  issuance  of  such  rights,  warrants  or  options  by a
               fraction, of which

                    (2) the numerator shall be (A) the number of shares of Class
               A  Common  Stock  outstanding  on the  date of  issuance  of such
               rights,  warrants or options  immediately prior to such issuance,
               plus (B) the number of shares which the aggregate  offering price
               of the total  number of shares so  offered  for  subscription  or
               purchase would purchase at such Current Market Price  (determined
               by  multiplying  such  total  number  of shares by the sum of the
               exercise price of such rights,  warrants or options plus the fair
               market value of any  consideration  paid to the  Corporation  for
               such  rights,  warrants  or options and  dividing  the product so
               obtained by such Current Market Price), and of which

                    (3) the  denominator  shall be (A) the  number  of shares of
               Class A Common Stock  outstanding on the date of issuance of such
               rights, warrants or options,  immediately prior to such issuance,
               plus (B) the number of additional  shares of Class A Common Stock
               which are so offered for subscription or purchase.

               Such adjustment shall become effective immediately, except as
          provided  in  subparagraph  (v) below,  after the record  date for the
          determination of holders entitled to receive such rights,  warrants or
          options.

               (iii) Except as otherwise provided in subparagraph (vi) below, in
          case the Corporation  shall distribute to substantially all holders of
          Class A Common Stock  evidences  of  indebtedness,  equity  securities
          (including equity interests in the Corporation's  subsidiaries)  other
          than Class A Common Stock or other assets (other

                                       -8-

<PAGE>



          than cash dividends), or shall distribute to substantially all holders
          of Class A Common  Stock  rights,  warrants or options to subscribe to
          securities  (other than those referred to in subparagraph (ii) above),
          then in each such case the Conversion  Price shall be adjusted so that
          the  same  shall  equal  the  price   determined  by  multiplying  the
          Conversion  Price  in  effect  immediately  prior  to the date of such
          distribution by a fraction of which the numerator shall be the Current
          Market Price per share (as defined in subparagraph  (iv) below) of the
          Class A Common Stock on the record date mentioned  below less the then
          fair  market  value  of  the  portion  of  the  assets,  evidences  of
          indebtedness   and  equity   securities  so  distributed  or  of  such
          subscription  rights,  warrants or options  applicable to one share of
          Class A Common  Stock,  and of  which  the  denominator  shall be such
          Current  Market Price per share of the Class A Common  Stock.  For the
          purposes of this subparagraph (iii), in the event of a distribution of
          shares of capital  stock or other  securities  of any  subsidiary as a
          dividend on shares of Class A Common Stock, the then fair market value
          of the shares or other securities so distributed shall be deemed to be
          the market value of such shares or other  securities.  Such adjustment
          shall become effective immediately, except as provided in subparagraph
          (v) below, after the record date for the determination of stockholders
          entitled to receive such distribution.

               (iv) For the purpose of any computation under  subparagraphs (ii)
          and (iii) above, the Current Market Price per share of Common Stock on
          any date shall be deemed to be the  average of the Last Sale Prices of
          a share of Class A Common Stock for the five (5)  consecutive  Trading
          Days  commencing  not more than twenty (20) Trading  Days before,  and
          ending not later than,  the  earlier of the date in  question  and the
          date before the "ex" date with respect to the issuance or distribution
          requiring  such  computation.  For  purposes  of this  Certificate  of
          Designation,  the term (i) "Last Sale Price" means the last sale price
          of the Class A Common Stock as reported on the composite  tape for New
          York Stock  Exchange  listed  stocks (or if not listed or  admitted to
          trading on such exchange,  then on the principal  national  securities
          exchange  on which the Class A Common  Stock is listed or  admitted to
          trading,  or, if not listed or  admitted  to  trading on any  national
          securities exchange,  on NASDAQ or a similar organization if NASDAQ is
          no longer reporting  information) on the last Trading Day prior to the
          date in question or if no such sale takes place on such day,

                                       -9-


<PAGE>



          the last sale price for such day shall be the  average of the  closing
          bid and asked prices regular way on the New York Stock Exchange (or if
          not  listed or  admitted  to  trading  on such  exchange,  then on the
          principal  national  securities  exchange  on which the Class A Common
          Stock is listed or admitted to trading,  or, if not listed or admitted
          to trading on any national securities exchange, on NASDAQ or a similar
          organization  if NASDAQ is no longer  reporting  information)  on such
          day;  (ii)  "Trading  Day"  means  each  Monday,  Tuesday,  Wednesday,
          Thursday and Friday,  other than any day on which  securities  are not
          traded on the  applicable  securities  exchange  or in the  applicable
          securities  market;  and (iii) "'ex' date",  when used with respect to
          any issuance or distribution,  means the first date on which the Class
          A Common Stock trades regular way on the principal national securities
          exchange  on which the Class A Common  Stock is listed or  admitted to
          trading  (or if not so  listed  or  admitted  on  NASDAQ  or a similar
          organization  if NASDAQ is no longer  reporting  trading  information)
          without the right to receive such issuance or distribution.

               (v) In any case in  which  this  Section  shall  require  that an
          adjustment  be  made   immediately   following  a  record  date,   the
          Corporation  may elect to defer the  effectiveness  of such adjustment
          (but in no event  until a date  later than the  effective  time of the
          event giving rise to such  adjustment),  in which case the Corporation
          shall,  with respect to any security  converted after such record date
          and before  such  adjustment  shall have  become  effective  (a) defer
          making any cash payment or issuing to the holder of such  security the
          number  of shares of  Common  Stock  and  other  capital  stock of the
          Corporation  issuable upon such  conversion in excess of the number of
          shares of Common  Stock and  other  capital  stock of the  Corporation
          issuable  thereupon only on the basis of the Conversion Price prior to
          adjustment,  and (b) not later than five (5) business  days after such
          adjustment  shall  have  become  effective,  pay to  such  holder  the
          appropriate  cash  payment  and issue to such  holder  the  additional
          shares of Common  Stock and  other  capital  stock of the  Corporation
          issuable on such conversion.

               (vi) No adjustment in the  Conversion  Price shall be required if
          securityholders   are  offered  the  right  to   participate   in  the
          transaction  on a basis and with notice that the Board  determines  in
          good faith to be fair and appropriate in light of the basis and notice
          on which holders of Class A Common Stock participate in

                                      -10-

<PAGE>



         the  transaction.  In addition,  no adjustment in the Conversion  Price
         shall be required unless such  adjustment  would require an increase or
         decrease of at least 1% in the  Conversion  Price;  provided,  however,
         that any adjustments  which by reason of this subparagraph (vi) are not
         required to be made shall be carried  forward and taken into account in
         any subsequent adjustment. All calculations under this Section shall be
         made to the nearest cent or to the nearest one-hundredth of a share, as
         the case may be.

                   (vii)  Whenever  the  Conversion  Price is adjusted as herein
         provided,  the Corporation shall promptly mail or cause to be mailed to
         each holder of Convertible  Preferred Stock at such holder's address as
         the same  appears  on the stock  transfer  books of the  Corporation  a
         notice  setting forth the  Conversion  Price after such  adjustment and
         setting forth in reasonable  detail the facts requiring such adjustment
         and the  calculations  on which the  adjustment is based,  which notice
         shall be conclusive evidence of the correctness of such adjustment.

                  (viii) To the extent  permitted by law, the  Corporation  from
         time to time may  reduce  the  Conversion  Price by any  amount for any
         period of at least  twenty (20) days (or such other  period as may then
         be required by applicable  law), if the Board has made a  determination
         in good faith that such reduction would be in the best interests of the
         Corporation,  which determination shall be conclusive.  No reduction in
         the  Conversion  Price  pursuant  to  this  subparagraph  shall  become
         effective unless the Corporation  shall have mailed a notice,  at least
         fifteen  (15)  days  prior  to the  date on  which  such  reduction  is
         scheduled  to  become  effective,  to  each  holder  of  shares  of the
         Convertible  Preferred Stock. Such notice shall be given by first class
         mail, postage prepaid,  at such holder's address as the same appears on
         the stock  transfer books of the  Corporation.  Such notice shall state
         the amount per share by which the Conversion  Price will be reduced and
         the period for which such reduction will be in effect.

                    (ix) At its option,  the Corporation may make such reduction
         in the Conversion  Price,  in addition to those  otherwise  required by
         this  Section,  as the Board deems  advisable  to avoid or diminish any
         income  tax to  holders  of Class A  Common  Stock  resulting  from any
         dividend or  distribution of stock (or rights to acquire stock) or from
         any event treated as such for income tax purposes;  provided,  however,
         that any such reduction

                                      -11-


<PAGE>



         shall not be  effective  until  written  evidence  of the action of the
         Board  authorizing  such reduction shall be filed with the secretary of
         the Corporation and notice thereof shall have been given by first class
         mail,  postage  prepaid,  to each  holder of shares of the  Convertible
         Preferred  Stock at such  holder's  address as the same  appears on the
         stock transfer books of the Corporation.

          (c) Consolidation, Merger or Sale of Assets

          If any transaction shall occur,  including without  limitation (i) any
recapitalization  or  reclassification  of shares of Class A Common Stock (other
than a change in par value,  or from par value to no par  value,  or from no par
value to par value,  or as a result of a subdivision or combination of the Class
A Common Stock),  (ii) any  consolidation  or merger of the Corporation  with or
into another person or any merger of another person into the Corporation  (other
than a merger that does not result in a reclassification,  conversion,  exchange
or cancellation  of Class A Common Stock),  (iii) any sale or transfer of all or
substantially all of the assets of the Corporation, or (iv) any compulsory share
exchange,  pursuant  to which  any  holders  of Class A  Common  Stock  shall be
entitled to receive other securities,  cash or other property,  then appropriate
provision  shall  be made so that  the  holder  of  each  share  of  Convertible
Preferred Stock then outstanding shall have the right thereafter to convert such
share only into the kind and amount of the  securities,  cash or other  property
that would have been  receivable upon such  recapitalization,  reclassification,
consolidation,  merger,  sale,  transfer,  or share  exchange by a holder of the
number of shares of Class A Common Stock issuable upon  conversion of such share
of  Convertible  Preferred  Stock  immediately  prior to such  recapitalization,
reclassification, consolidation, merger, sale, transfer or share exchange, after
giving effect to any  adjustment  in the  Conversion  Price in  accordance  with
Section 9 hereof,  and the  Corporation  shall not enter  into any such  merger,
consolidation  or sale,  unless  the  person  formed  by such  consolidation  or
resulting  from such merger or that  acquires  such assets or that  acquires the
Corporation's  shares,  as  the  case  may  be,  shall  make  provisions  in its
certificate of  incorporation  or other  constituent  document to establish such
right.  Such certificate of incorporation  or other  constituent  document shall
provide for  adjustments  that,  for events  subsequent to the effective date of
such certificate of incorporation or other  constituent  documents,  shall be as
nearly equivalent as may be practicable to the relevant adjustments provided for
in this Section.

                                      -12-

          (d) Accrued  Dividends.  Dividends  shall cease to accrue on shares of
the Convertible  Preferred Stock  surrendered for conversion into Class A Common
Stock.

          (e)  Mechanics  of  Conversion.   Before  any  holder  of  Convertible
Preferred  Stock  shall be  entitled  to convert the same into shares of Class A
Common  Stock  or  other  securities,  cash or  other  property  and to  receive
certificates  or other  evidences  of  ownership  therefor,  such  holder  shall
surrender the certificate or certificates for the Convertible Preferred Stock to
be converted, duly endorsed, at the office of the Corporation or of any transfer
agent for the Convertible  Preferred Stock, and shall give written notice to the
Corporation  at such  office that such  holder  elects to convert the same.  The
Corporation shall,  within ten (10) days after such delivery,  issue and deliver
at such  office to such  holder of the  Convertible  Preferred  Stock (or to any
other person specified in the notice delivered by such holder), a certificate or
certificates  for the  number  of  shares  of  Class A  Common  Stock  or  other
securities,  cash or other  property to which such  holder  shall be entitled as
aforesaid and a check payable to the holder for any cash amounts  payable as the
result of a conversion into  fractional  shares of Class A Common Stock or other
securities.  Such conversion shall be deemed to have been made immediately prior
to the  close  of  business  on the  date of such  surrender  of the  shares  of
Convertible Preferred Stock to be converted,  and the person or persons entitled
to receive  the shares of Class A Common  Stock  issuable  upon such  conversion
shall be treated for all purposes as the record holder or holders of such shares
of Class A Common Stock on such date. In case any  certificate for shares of the
Convertible  Preferred  Stock shall be surrendered for conversion of only a part
of the shares represented thereby, the Corporation shall deliver within ten (10)
days at such  office  to or upon the  written  order of the  holder  thereof,  a
certificate or  certificates  for the number of shares of Convertible  Preferred
Stock represented by such surrendered certificate which are not being converted.
Notwithstanding  the foregoing,  the Corporation shall not be obligated to issue
certificates  or other  evidences of ownership  evidencing the shares of Class A
Common  Stock or other  securities  issuable  upon such  conversion  unless  the
certificates  evidencing the Convertible Preferred Stock are either delivered to
the  Corporation or its transfer agent or the  Corporation or its transfer agent
shall  have  received   evidence   satisfactory   to  it  evidencing  that  such
certificates  have  been  lost,  stolen  or  destroyed  and the  holder  of such
Convertible   Preferred   Stock  executes  an  agreement   satisfactory  to  the
Corporation to indemnify the Corporation from any loss incurred by it in

                                      -13-


<PAGE>



connection  with  such  certificates  and,  if  requested  by  the  Corporation,
furnishes an indemnity bond of a recognized  insurance  company in an amount and
on terms  satisfactory  to the  Corporation  with respect to any such loss.  The
issuance of  certificates  or other  evidences of ownership of shares of Class A
Common  Stock  or  other  securities  issuable  upon  conversion  of  shares  of
Convertible  Preferred  Stock  shall be made  without  charge to the  converting
holder  for any tax  imposed  in  respect  of the  issuance  thereof;  provided,
however,  that the Corporation shall not be required to pay any tax which may be
payable with  respect to any transfer  involved in the issue and delivery of any
certificate  or other  evidence  of  ownership  in a name other than that of the
holder of the shares of Convertible Preferred Stock being converted.

          (f)  No   Impairment.   The   Corporation   will  not,   through   any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities  or any other  voluntary  action,  avoid or seek to avoid the
observance  or  performance  of any of the  terms to be  observed  or  performed
hereunder by the Corporation,  but will at all times in good faith assist in the
carrying  out of all the  provisions  of this Section 6 and in the taking of all
such  action  as may be  necessary  or  appropriate  in  order  to  protect  the
conversion  rights of the holders of the  Convertible  Preferred  Stock  against
impairment.

          SECTION  7.  (a)  Optional  Redemption.   After  July  15,  1999,  the
Corporation may, at its option,  redeem all or from time to time any part of the
shares of Convertible  Preferred Stock, out of funds legally available therefor,
upon  giving  a  notice  of  redemption  as set  forth  below  at the  following
redemption prices per share (expressed as a percentage of the $1,000 liquidation
preference  thereof),  plus an amount equal to accrued and unpaid dividends,  if
any, up to but excluding the date fixed for  redemption,  if redeemed during the
twelve-month period commencing  immediately after July 15 of the years indicated
below:

                                                    Redemption
               Year                                    Price

               1999..............................      104.9%
               2000..............................      104.2
               2001..............................      103.5
               2002..............................      102.8
               2003..............................      102.1
               2004..............................      101.4
               2005..............................      100.7
               2006 and thereafter...............      100.0

                                      -14-


<PAGE>




          If  fewer  than  all  of the  outstanding  shares  of the  Convertible
Preferred Stock are to be redeemed, the number of shares to be redeemed shall be
determined  by the Board in good  faith and the  shares to be  redeemed  will be
determined  pro rata as nearly as  practicable,  or by such other  method as the
Board may determine to be fair and appropriate.  In the event that any quarterly
dividends  payable  on the  Convertible  Preferred  Stock  are in  arrears,  the
Convertible Preferred Stock may not be redeemed unless all outstanding shares of
Convertible  Preferred  Stock are  simultaneously  redeemed  or the  outstanding
shares of the Convertible Preferred Stock are redeemed on a pro rata basis.

          Notice of redemption shall be given by mail, not less than thirty (30)
nor more than sixty (60) days prior to the date fixed for redemption thereof, to
each record holder of the shares of Convertible  Preferred  Stock to be redeemed
at the address of such holder in the stock  register  of the  Corporation.  If a
notice of redemption  has been given,  from and after the  specified  redemption
date  (unless  the  Corporation  defaults  in making  payment of the  redemption
price),  dividends on the  Convertible  Preferred Stock so called for redemption
will cease to accrue,  such shares  will no longer be deemed to be  outstanding,
and all rights of the holders thereof as stockholders of the Corporation (except
the right to receive the redemption price) will cease.

          SECTION 8. Payment of Excess Cash Dividends.  If the Corporation shall
declare and pay cash  dividends on the Class A Common Stock in an annualized per
share amount which exceeds the greater of (i) the annualized per share amount of
the immediately preceding cash dividend on the Class A Common Stock (as adjusted
to reflect any of the events  described in Section 6 hereof) and (ii) 15% of the
Last Sale Price of the Class A Common  Stock as of the Trading  Day  immediately
preceding the date of  declaration of such dividend (the per share amount of any
such  excess,  to the  extent of such  excess,  being  herein  called an "Excess
Amount"),  then in any such event the holders of the Convertible Preferred Stock
then outstanding  shall have the right to receive,  and the Corporation will pay
to each such  holder,  at the time of the  payment  of the Class A Common  Stock
dividend,  an amount equal to such Excess  Amount (on the basis of the number of
shares of Class A Common  Stock that would have been  issued to such holder upon
conversion of the Convertible  Preferred Stock held by such holder on the record
date for the payment of such dividend).

          SECTION 9. Change in Control.  If there occurs a Change in Control (as
hereinafter defined) with respect to

                                      -15-


<PAGE>



the  Corporation,  then shares of Convertible  Preferred  Stock may be converted
(the "Special Conversion  Rights"),  at the option of the holders thereof at any
time from the date of such Change in Control until the  expiration of forty-five
(45) days after the date of the Conversion  Notice (as defined below),  into the
number of shares of Class A Common Stock  determined  by dividing (i) the $1,000
liquidation  preference of the  Convertible  Preferred  Stock,  plus accrued and
unpaid dividends,  if any, up to but excluding the date of the Change in Control
by (ii) the Special Conversion Price (as defined below). The "Special Conversion
Price"  shall be an amount  equal to the  greater of (i) the average of the Last
Sale  Prices of a share of Class A Common  Stock  for the last five (5)  Trading
Days  before  the  Change  in  Control  or (ii) 66 2/3% of the Last  Sale  Price
(adjusted for any stock splits or  combinations)  of the Class A Common Stock as
of the date  immediately  prior to the filing of this Certificate of Designation
with the Secretary of State of Delaware.

          Within five (5) days after the occurrence of a Change in Control,  the
Corporation  shall give notice of the occurrence of the Change in Control and of
the Special Conversion Rights set forth herein in accordance with the procedures
set forth below to each holder of a share of  Convertible  Preferred  Stock (the
"Conversion Notice").

          Each Conversion Notice shall state:

               (1) that a Change in Control has occurred  (and shall specify the
          date of occurrence),  and that the holder's Special  Conversion Rights
          may be exercised in accordance with this Section;

               (2) the expiration date of the Special  Conversion Rights and the
          Special Conversion Price;

               (3) that a holder of a share of Convertible Preferred Stock which
          desires to exercise the Special  Conversion  Rights must deliver on or
          before  the  fifth  day prior to the  expiration  date of the  Special
          Conversion  Rights written  notice to the  Corporation of the holder's
          exercise of such option, together with the certificate evidencing such
          holder's  shares with respect to which the option is being  exercised,
          duly endorsed for transfer;

               (4) the applicable  Special  Conversion  Price and the Conversion
          Price;

                                      -16-


<PAGE>



               (5) a description of the procedures which a holder must follow to
          exercise its Special Conversion Rights;

               (6) that  holders of shares of the  Convertible  Preferred  Stock
          electing to have such shares  converted  will be required to surrender
          the certificates evidencing such shares of Convertible Preferred Stock
          for delivery of shares of Class A Common Stock; and

               (7) that the Corporation has the right, at its option, to pay any
          holder electing to exercise the Special Conversion Rights an amount of
          cash equal to the $1,000 liquidation preference,  plus an amount equal
          to any accrued and unpaid dividends, in which event no conversion into
          Class A Common Stock will occur.

          The  Conversion  Notice  shall be given by first class  mail,  postage
paid, to the holders of record of the shares of the Convertible  Preferred Stock
at their  respective  addresses as the same shall  appear on the stock  transfer
books of the Corporation.

          No failure of the Corporation to give the foregoing  Conversion Notice
shall limit any holder's right to exercise its Special Conversion Rights.

          Exercise of the Special  Conversion Rights by the holder of a share of
Convertible Preferred Stock will be irrevocable. The Corporation shall not enter
into  any  consolidation,  merger  or  sale  of  assets  unless,  in  connection
therewith,  the holders of Convertible  Preferred Stock exercising their Special
Conversion Rights will be entitled to receive the same consideration as received
for the  number of shares of Class A Common  Stock into  which  their  shares of
Convertible  Preferred  Stock would have been converted  pursuant to the Special
Conversion  Rights. The Special Conversion Rights are in addition to the regular
conversion rights that apply to the Convertible Preferred Stock.

          The  Corporation  may,  at its  option,  elect to pay  holders  of the
Convertible Preferred Stock exercising their Special Conversion Rights an amount
in cash equal to the $1,000 liquidation  preference of the Convertible Preferred
Stock, plus an amount equal to any accrued and unpaid  dividends,  if any, up to
but  excluding  the date of the Change in Control,  in which event no conversion
pursuant to the exercise of the Special Conversion Rights will occur,

                                      -17-

unless the Corporation defaults in making payment of such amount.

          A "Change in Control" is deemed to have  occurred  when (i) any person
or group other than one or more of Steven B.  Dodge,  Thomas H.  Stoner,  any of
their  affiliates  or any person  employed by the  Corporation  in a  management
capacity  as of June 19,  1996 (or any  group of which  any of them is a member,
collectively, a "Permitted Owner") acquires beneficial ownership of, directly or
indirectly,  shares of capital  stock of the  Corporation  sufficient to entitle
such person to exercise  more than 50% of the total  voting power of all classes
of capital stock entitled to vote in elections of directors (whether by means of
an  exchange   offer,   liquidation,   tender  offer,   consolidation,   merger,
combination,  reclassification,  recapitalization  or  otherwise),  or (ii)  the
Corporation  sells,  leases,  exchanges or transfers  (in one  transaction  or a
series of related  transactions)  all or substantially  all of its assets to any
person or group (in each  instance,  as the term  "person" or "group" is used in
Section  13(d)(3)  or  14(d)(2)  of the  Securities  Exchange  Act of  1934,  as
amended), other than one or more Permitted Owners.

          SECTION 10. Exchange Provisions.  (a) Shares of Convertible Stock will
be exchangeable at the option of the Corporation, out of funds legally available
therefor,  in whole but not in part,  on any March 31, June 30,  September 30 or
December 31 commencing June 30, 1997 (a "Debenture Exchange Date"),  through the
issuance of the  Corporation's 7% Convertible  Subordinated  Debentures due 2011
(the  "Exchange  Debentures")  in  redemption  of and in exchange  for shares of
Convertible  Preferred  Stock,  in the manner  provided in this  Section 10. The
Exchange Debentures will be subject to the terms and conditions of the indenture
dated June 25, 1996 (the "Indenture") between the Corporation and the Trustee, a
copy of which is on file at the principal  executive offices of the Corporation.
The  "Trustee"  is Bank of  Montreal  Trust  Company  or any  successor  Trustee
appointed in accordance with the terms of the Indenture.

          (b)  Holders of the  Convertible  Preferred  Stock will be entitled to
receive  Exchange  Debentures at the rate of $1,000 principal amount of Exchange
Debentures for each share of Convertible  Preferred Stock.  Such exchange may be
made  only if,  at the time of the  exchange,  (i)  there  shall be no  dividend
arrearage  (including the dividend payable on the date of exchange) on shares of
Convertible Preferred Stock, and (ii) no Event of Default (as defined in the

                                      -18-


<PAGE>



Indenture) under the Indenture shall have occurred and be continuing.

          (c) The  Corporation  will  mail  notice  of its  intention  to redeem
through such an exchange to each holder of record of the  Convertible  Preferred
Stock not less  than  thirty  (30) nor more than  sixty  (60)  days  before  the
Debenture Exchange Date. Such notice shall be given by first class mail, postage
prepaid,  to the holders of record of shares of Convertible  Preferred  Stock at
their respective  addresses as the same shall appear on the stock transfer books
of the Corporation,  specifying the Debenture  Exchange Date and the place where
certificates for shares of Convertible Preferred Stock are to be surrendered for
Exchange  Debentures  and stating that  dividends  on shares of the  Convertible
Preferred Stock will cease to accrue on the Debenture Exchange Date, but neither
failure to mail such notice,  nor any defect therein or in the mailing  thereof,
to any  particular  holder  shall  affect the  sufficiency  of the notice or the
validity of the proceedings for exchange with respect to the other holders.  Any
notice  which was mailed in the manner  herein  provided  shall be  conclusively
presumed to have been duly given whether or not the holder  receives the notice.
If notice of exchange has been given  pursuant to this  subsection  then (unless
the  Corporation  defaults in issuing  Exchange  Debentures  in exchange for the
Convertible Preferred Stock or fails to pay or set aside for payment accrued and
unpaid  dividends on the Convertible  Preferred Stock as set forth in subsection
(d) below and  notwithstanding  that any  certificates for shares of Convertible
Preferred  Stock  have not  been  surrendered  for  exchange)  on the  Debenture
Exchange  Date the  holders  of  Convertible  Preferred  Stock  will cease to be
stockholders with respect to such shares and will have no interests in or claims
against the Corporation by virtue thereof (except the right to receive  Exchange
Debentures  in  exchange  therefor  and  accrued  and  unpaid  dividends  on the
Convertible  Preferred  Stock to the Debenture  Exchange  Date) and will have no
voting,  conversion or other rights with respect to such shares,  and all shares
of Convertible Preferred Stock will no longer be outstanding.

          Upon the surrender (and  endorsement,  if required by the Corporation)
in  accordance  with such notice of the  certificate  for shares of  Convertible
Preferred Stock,  such certificates  shall be exchanged for Exchange  Debentures
and such  accrued  and unpaid  dividends  in  accordance  with this  subsection.
Notwithstanding  the  foregoing,  if notice of redemption  and exchange has been
given  pursuant  to this  subsection  and any  holder of  shares of  Convertible
Preferred Stock shall, prior to the close of business on the fifth day

                                      -19-

Convertible Preferred Stock held by such holder (accompanied by a certificate or
certificates for such shares, duly endorsed or assigned to the Corporation,  and
any necessary transfer tax payment, as required by Section 6 hereof),  then such
exchange  shall not become  effective  with respect to such shares and any funds
which have been deposited by the  Corporation,  or on its behalf,  with a paying
agent or segregated and held in trust by the  Corporation for the redemption and

          (d) No shares of  Convertible  Preferred  Stock may be  exchanged  for
Exchange Debentures unless the Corporation has paid or set aside for the benefit
of the  holders  of the  Convertible  Preferred  Stock all  accrued  and  unpaid
dividends on the Convertible Preferred Stock to the Debenture Exchange Date.

          SECTION 11. Status of Reacquired  Shares. If shares of the Convertible

Section 10 hereof,  the shares so converted,  redeemed or exchanged shall,  upon
compliance with any statutory requirements,  assume the status of authorized but
unissued shares of preferred stock of the Corporation.

          SECTION  12.  Reserved  Shares.  So long as any shares of  Convertible
Preferred Stock remain outstanding,  the Corporation agrees to keep reserved for
issuance in connection with the conversion of the Convertible Preferred Stock at
all times a number of authorized but unissued  shares of Class A Common Stock at
least  equal to the  number  of  shares of Class A Common  Stock  issuable  upon
conversion (including, without limitation, as a consequence of the anti-dilution

outstanding at such time.

          SECTION  13.  Notices.  All  notices,   requests,  demands  and  other
communications  hereunder  shall be in writing  and shall be deemed to have been
duly given if delivered by hand or by first class mail, postage prepaid, or when

or  prospectively)  with the written  consent of the Corporation and the vote or
consent  of the  holders of a majority  of the shares of  Convertible  Preferred
Stock then outstanding, and any amendment or waiver so effected shall be binding
upon the Corporation and all holders of the Convertible Preferred Stock.
