                          General Corporation Law of Nevada

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


    Each of Charles W. Ergen, President, and David K. Moskowitz, the Senior
Vice President, General Counsel and Secretary of EchoStar Communications
Corporation (the "Issuer"), a corporation organized and existing under the
General Corporation Law of the State of Nevada, does hereby certify that
pursuant to authority conferred upon the Board of Directors of the Issuer by its
Articles of Incorporation and pursuant to the provisions of Section 78.1955 of
the General Corporation Law of the State of Nevada, the Board of Directors, on
October 27, 1997, adopted the following resolution establishing the Issuer's
63/4% Series C Cumulative Convertible Preferred Stock, which resolution remains
in full force and effect.  Certain capitalized terms used herein are defined in
Article 11.

    RESOLVED, that pursuant to the authority vested in the Board of
    Directors of the Corporation by the Articles of Incorporation, the
    Board of Directors does hereby provide for the issue of a series of
    Preferred Stock, $0.01 par value, of the Corporation, to be designated
    "6 3/4% Series C Cumulative 


                                      -1-



    Convertible Preferred Stock" (referred to herein as the "Series C 
    Preferred Stock"), having the number of shares and, to the extent that 
    the designations, powers, preferences and relative and other special 
    rights and the qualifications, limitations and restrictions of such 
    Series C Preferred Stock are not stated and expressed in the Articles of 
    Incorporation, the powers, preferences and relative and other special 
    rights and the qualifications, limitations and restrictions thereof, as 
    follows:

1   DESIGNATION AND NUMBER OF SHARES

    1.1  The series will be known as the 6 3/4% Series C Cumulative Convertible
Preferred Stock.

    1.2  The Series C Preferred Stock will be a series consisting of 2,300,000
shares of the authorized but unissued preferred stock of this corporation (the
"Issuer").

2   DIVIDENDS

    2.1  Holders of Series C Preferred Stock will be entitled to receive, when,
as and if declared by the Board of Directors, out of funds legally available
therefor, dividends on the Series C Preferred Stock at a rate per annum equal
to 6 3/4% of the liquidation preference per share.

         (a)  All dividends will be cumulative, whether or not earned or
declared, on a quarterly basis on February 1, May 1, August 1, and November 1 of
each year, commencing February 1, 2000 (each such date being referred to herein
as a "Dividend Payment Date").  Each distribution in the form of a dividend
shall be payable in arrears to Holders of record as they appear on the stock
books of the Issuer on each record date as established by the Board of Directors
of the Issuer (the "Dividend Payment Record Date") not more than 60 nor less
than ten days preceding a Dividend Payment Date.

         (i) Dividends payable on the Series C Preferred Stock for each full
    dividend period will be computed by dividing the annual dividend rate by
    four.  Dividends payable on the Series C Preferred Stock 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.  

         (ii) The Series C Preferred Stock will not be entitled to any dividend
    whether payable in cash, property or securities, in excess of the full
    cumulative dividends.


                                      -2-



         (iii) No interest, or sum of money in lieu of interest, will be
    payable in respect of any accumulated and unpaid dividends.

         (b)  Dividends, to the extent declared by the Issuer's Board of
Directors, may, at the option of the Issuer, be paid in cash, by delivery of
fully paid and nonassessable shares of Class A Common Stock, or a combination
thereof.  If the Issuer elects to pay dividends in shares of Class A Common
Stock, the number of shares of Class A Common Stock to be distributed will be
calculated by dividing such payment by 95% of the Market Value as of the
Dividend Payment Record Date.

    2.2  (a) Subject to this Section 2.2, 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:

              (i) full cumulative dividends on the Series C Preferred Stock
    shall have been or contemporaneously are declared and paid in full through
    the immediately preceding Dividend Payment Date, and

              (ii) if the dividend on the Parity Securities is declared as
    payable in cash, a sum in cash is set apart for the next succeeding payment
    on the Series C Preferred Stock at the next succeeding Dividend Payment
    Date.

If full dividends are not so paid, the Series C Preferred Stock will share
dividends pro rata with any Parity Securities.

         (b)  No dividends may be paid or set apart for payment on Parity
Securities or Junior Securities, except dividends:

              (i)  on Junior Securities payable in additional shares of Junior
    Securities, and 

              (ii) on Parity Securities payable in additional shares of Parity
    Securities or Junior Securities,

provided, however, that, notwithstanding the provisions of Sections 2.2(a)(ii),
2.2(b)(i) and 2.2(b)(ii), whether or not full dividends have been or will be
paid in cash on the shares of the Series C Preferred Stock, the Issuer shall be
entitled to declare and pay cash dividends on Parity Securities and Junior
Securities to the extent that


                                      -3-



              (1)  the funds for such cash dividend payments are derived,
    directly or indirectly, from the proceeds of an offering of Parity
    Securities or Junior Securities with respect to which such cash dividends
    are to be paid (or a concurrent offering of related securities), and

              (2)  provided that in connection with such offering it is
    disclosed to the purchasers of such Parity Securities or Junior Securities,
    as the case may be, in an offering memorandum, prospectus, or similar
    communication, that a portion of the proceeds thereof may be used for the
    payment of cash dividends on such securities (any transaction in which the
    Issuer obtains the right to make cash dividend payments on Parity
    Securities or Junior Securities pursuant to Clauses 2.2(b)(1) and 2.2(b)(2)
    being referred to as a "Self-Funding Event").

         (c) No Junior Securities or Parity Securities may be repurchased,
redeemed or otherwise retired nor may funds be set apart for payment with
respect thereto if full cumulative and unpaid dividends have not been paid in
cash on the Series C Preferred Stock through the immediately preceding Dividend
Payment Date or contemporaneously provided for; provided that, notwithstanding
the foregoing: 

              (i) cash dividends may be paid on Parity Securities and Junior
    Securities to the extent permitted by Section 2.2(b), and

              (ii) the Issuer may repurchase, redeem or otherwise retire or set
    aside funds for those purposes with respect to any Parity Securities or
    Junior Securities in exchange for or out of the net proceeds of the
    substantially concurrent sale (other than to a Subsidiary of the Issuer) of
    other Parity Securities or Junior Securities, as the case may be, of the
    Issuer.

         (d)  Reserved.

         (e)  Notwithstanding the foregoing, if full dividends have not been
declared and paid or set apart on the Series C Preferred Stock and any other
Parity Securities, dividends may be declared and paid on the Series C Preferred
Stock and such other Parity Securities so long as the dividends are declared and
paid PRO RATA so that the amounts of dividends declared per share on the Series
C Preferred Stock and such other Parity Securities will in all cases bear to
each other the same ratio that accrued and unpaid dividends per share on the
shares of the Series C Preferred Stock and such other Parity Securities bear to
each other; provided, that if such dividends are paid in cash on the other
Parity Securities, dividends will also be paid in cash on the Series C Preferred
Stock.


                                      -4-



         (f)  (i)  Except as provided in Clause (ii) of this Section 2.2(f),
the Holders of shares of the Series C Preferred Stock at the close of business
on a Dividend Payment Record Date will be entitled to receive the dividend
payment on those shares on the corresponding Dividend Payment Date
notwithstanding the subsequent conversion thereof or the Issuer's default in
payment of the dividend due on that Dividend Payment Date.  (ii)   Holders of
shares called for redemption on a Redemption Date which falls between the
Dividend Payment Record Date and the Dividend Payment Date will be entitled to
receive such dividend on such Redemption Date and will not be entitled to such
payment pursuant to Clause (i) hereof.  (iii)  Except as provided in Clauses (i)
and (ii) of this Section 2.2(f), the Issuer shall make no payment or allowance
for unpaid dividends, whether or not in arrears, on converted shares or for
dividends on the shares of Class A Common Stock issued upon conversion.

3   RANKING

    3.1  The Series C Preferred Stock will, with respect to dividend
distributions and distributions upon the liquidation, winding-up or dissolution
of the Issuer, rank:

         (a) senior to all classes of Common Stock and (except as described in
Sections 3.3 and 3.4, below) to each series of preferred stock existing on the
date of this Certificate of Designation and each other class of capital stock or
series of preferred stock issued by the Issuer, which is established after the
date of this Certificate of Designation, the terms of which do not expressly
provide that such class or series will rank senior to or on a parity with the
Series C Preferred Stock as to dividend distributions and distributions upon the
liquidation, winding-up or dissolution of the Issuer (collectively, with the
Common Stock, referred to as the "Junior Securities");

         (b) subject to certain conditions, on a parity with any class of
capital stock or series of preferred stock issued by the Issuer, which is

Directors, the terms of which expressly provide that such class or series will
rank on a parity with the Series C Preferred Stock as to dividend distributions

Securities"); and

stock or series of preferred stock issued by the Issuer, which is established
after the date of this Certificate of Designation by the Board of Directors, the
terms of which expressly provide that such class or series will rank senior to
the Series C Preferred Stock as to dividend distributions and distributions upon

incorporation to authorize one or more additional series of preferred stock,
file certificates of designation, and issue without restriction, from time to
time, any series of Junior Securities, Parity Securities or Senior Securities.

Security.

    3.4  The Issuer's Series B Preferred Stock is hereby designated a Senior
Security.

4   CONVERSION.

    4.1(a)  Each Holder of Series C Preferred Stock shall have the right, at
its option, at any time and from time to time to convert, subject to the terms
and provisions of this Section 4, any or all of such Holder's shares of Series C
Preferred Stock.  In such case, the shares of Series C Preferred Stock shall be
converted into such number of fully paid and nonassessable shares of Class A
Common Stock as is equal, subject to Section 4.6, to:

    THE PRODUCT of the number of shares of Series C Preferred Stock being so
    converted MULTIPLIED BY 

    THE QUOTIENT OF (i) the Liquidation Preference DIVIDED BY (ii) the
    Conversion Price then in effect,

except that with respect to any share which shall be called for redemption such
right shall terminate at the close of business on the second Business Day
preceding the Redemption Date unless the Issuer shall default in making the
payment due upon redemption thereof.

         (b)  The conversion right of a Holder of Series C Preferred Stock
shall be exercised by the Holder by the surrender of the certificates
representing shares to be converted to the Issuer or to the Transfer Agent
accompanied by the Conversion Notice.

    Date, each converting Holder of Series C Preferred Stock shall be deemed to
    be the Holder of record of Class A Common Stock issuable upon conversion of
    such 


                                      -6-



    Holder's Series C Preferred Stock notwithstanding that the share register of
    the Issuer shall then be closed or that certificates representing such 
    Class A Common Stock shall not then be actually delivered to such person.

         (ii) Upon notice from the Issuer, each Holder of Series C Preferred
    Stock so converted shall promptly surrender to the Issuer or the Transfer
    Agent certificates representing the shares so converted (if not previously
    delivered), duly endorsed in blank or accompanied by proper instruments of
    transfer.

         (iii) On any Conversion Date, all rights with respect to the shares of
    Series C Preferred Stock so converted, including the rights, if any, to
    receive notices, will terminate, except the rights of Holders thereof
    to:(1) receive certificates for the number of shares of Class A Common
    Stock into which such shares of Series C Preferred Stock have been
    converted;(2) the payment in cash or shares of Class A Common Stock of any
    accumulated and unpaid dividends accrued thereon pursuant to Section 4.2
    hereof; and (3) exercise the rights to which they are entitled as Holders
    of Class A Common Stock.

         (c)  If the Conversion Date shall not be a Business Day, then such
conversion right shall be deemed exercised on the next Business Day.

    4.2    When shares of Series C Preferred Stock are converted pursuant to
this Section 4, all accumulated and unpaid dividends (whether or not declared or
currently payable) on the Series C Preferred Stock so converted to (and not
including) the Conversion Date shall be due and payable, at the Issuer's option,

         (a)  in cash; 

         (b)  in a number of fully paid and nonassessable shares of Class A
Common Stock equal to the quotient of (i)  the amount of accumulated and unpaid
dividends payable to the Holders of Series C Preferred Stock hereunder, DIVIDED
BY (ii) 95% of the Market Value for the period ending on the Conversion Date; or

         (c)  a combination thereof.

    4.3  The Conversion Price shall be subject to adjustment if any Conversion
Price Adjustment Event described in Section 4.3(a) occurs.  The adjustment will
be accomplished from time to time as described in Section 4.3(b).

         (a)  In case the Issuer shall at any time or from time to time:


                                      -7-



         (i) make a redemption payment or pay a dividend (or other distribution)
    payable in shares of Class A Common Stock to all Holders of any class of
    Capital Stock of the Issuer (other than the issuance of shares of Class A
    Common Stock in connection with the payment in redemption for, of dividends
    on, or the conversion of the Series C Preferred Stock);

         (ii) make any issuance to all Holders of shares of Common Stock of
    rights, options or warrants entitling them to subscribe for or purchase

    shares of Common Stock at less than Market Value as of the date of
    conversion or exchange; PROVIDED, HOWEVER, that no adjustment shall be made
    with respect to such a distribution to the extent the Holder of shares of
    Series C Preferred Stock would be entitled to receive such rights, option
    or warrants upon conversion at any time of shares of Series C Preferred
    Stock into Class A Common Stock and PROVIDED FURTHER that if such options
    or warrants are only exercisable upon the occurrence of certain triggering
    events, then the Conversion Price will not be adjusted until such
    triggering events occur,

         (iii) any subdivision, combination or reclassification of any class of
    Common Stock,

         (iv) any distribution consisting exclusively of cash (excluding any
    cash distributed upon a merger or consolidation to which Section 4.5
    applies) to all Holders of shares of any class of Common Stock (which
    distribution is not also being made to the holders of the Series C
    Preferred Stock based on the number of shares of Class A Common Stock into
    which the Series C Preferred Stock is then convertible unless the Class A
    Common Stock does not share PRO RATA in such distribution) in an aggregate
    amount that, combined together with (1) all other such all-cash
    distributions made within the then-preceding 12-months in respect of which

    adjustment has been made, exceeds 15% of the Issuer's Market Capitalization
    on the record date of such distribution,

         (v) the completion of a tender or exchange offer made by the Issuer or
    any of its Subsidiaries for shares of any class of Common Stock that
    involves an aggregate consideration that, together with (1) any cash and
    other consideration payable in a tender or exchange offer by the Issuer or
    any of its Subsidiaries for 


                                      -8-



    shares of any class of Common Stock expiring within the then-preceding 
    12-months in respect of which no adjustment has been made and (2) the 
    aggregate amount of any such all-cash distributions referred to in (iv) 
    above to all Holders of shares of any class of Common Stock within the 
    then-preceding 12-months in respect of which no adjustments have been 
    made, exceeds 15% of the Issuer's Market Capitalization just prior to the 
    expiration of such tender offer, or

         (vi) a distribution to all Holders of any class of Common Stock (which
    distribution is not also being made to the holders of the Series C
    Preferred Stock based on the number of shares of Class A Common Stock into

    rights, options, warrants and distributions referred to above).

(1) For example, where X=12 million shares, and 500,000 shares are being issued
in the Conversion Price Adjustment Event (Y=12,500,000), and CP is $32.00, the
Adjusted Conversion Price (ACP) is $30.72.

(2) For example, where X=12 million shares, and U=500,000 shares, MV is $40,
ExP is $35, and CP is $32.00, the Adjusted Conversion Price (ACP) is $31.83.  If
ExP is $0, the Adjusted Conversion Price (ACP) is $30.72.

(3) For example, where Cash distributed equals $20,000,000, Market
Capitalization equals $100,000,000 (15%MC=$15,000,000), CP equals $32.00 and
there are 2,000,000 shares of Series C Preferred Stock outstanding (C), the
Adjusted Conversion Price (ACP) is $29.50.

                                     -11-


     pursuant to the following formula:  CP-((TPur MULTIPLIED BY 
     (TOff/S-MV))/(#SH-TPur))=ACP.(4)

     There will be no adjustment to the Conversion Price pursuant to Clause

     Conversion Price in effect immediately before such event shall be adjusted
     pursuant to the following formula:  CP-(Value/#SH)=ACP.(5)

An adjustment made pursuant to this Section 4.3 shall become effective: (x) 
in the case of a Conversion Price Adjustment Event described in Section 
4.3(a)(i), (ii), (iv) or (vi), immediately following the close of business on 
the record date for the determination of Holders of Common Stock entitled to 
participate in such event; or (y) in the case of a Conversion Price 
Adjustment Event described in Section 4.3(a)(iii), the close of business on 
the day upon which such corporate action becomes effective; or (z) in the 
case of a Conversion Price Adjustment Event described in Section 4.3(a)(v), 
the close of business on the day of the completion of such tender offer or 
exchange offer.

         (c) Notwithstanding anything herein to the contrary, no adjustment 
under this Section 4.3 need be made to the Conversion Price unless such 
adjustment would require an increase or decrease of at least 1% of the 
Conversion Price then in effect.  Any lesser adjustment shall be carried 
forward and shall be made at the time, if ever, of and together with the next 
subsequent adjustment, which, together with any adjustment or adjustments so 
carried forward, shall amount to an increase or decrease of at least 1% of 
such Conversion Price.

         (d) Notwithstanding anything to the contrary contained in this 
Certificate of Designation, no Conversion Price adjustment will be made as a 
result of the issuance of Class A Common Stock on conversion of the Series A 
Preferred Stock, Series C Preferred Stock, or the Class B Common Stock.  

- -------------
(4) For example, where TOff/S is $45.00 at a time when MV is $35, CP equals
$32.00, 1,000,000 shares were purchased in the tender offer (TPur), and there
were 12,000,000 shares of the class outstanding (#SH), the Adjusted Conversion
Price (ACP) is $31.09.

(5) For example, where CP is $32.00, Value equals $1,500,000, and there were
12,000,000 shares of the class outstanding (#SH), ACP is $31.875.

                                     -12-


         (e)  Each event requiring adjustment to the Conversion Price shall 
require only a single adjustment even though more than one of the adjustment 
clauses set forth in Section 4.3(a), Section 4.4, or Section 4.5, may be 
applicable to such Conversion Price Adjustment Event.  

         (f)  If the Issuer shall take a record of the Holders of any class 
of its Capital Stock for the purpose of entitling them to receive a dividend 
or other distribution which would otherwise constitute a Conversion Price 
Adjustment Event, and shall thereafter and before the distribution to 
stockholders thereof legally abandon its plan to pay or deliver such dividend 
or distribution, then thereafter no adjustment in the Conversion Price then 
in effect shall be required by reason of the taking of such record.

         (g)  Upon any increase or decrease in the Conversion Price, then, 
and in each such case, the Issuer promptly shall deliver to each registered 
Holder of Series C Preferred Stock a certificate signed by an authorized 
officer of the Issuer, setting forth in reasonable detail the event requiring 
the adjustment and the method by which such adjustment was calculated and 
specifying the increased or decreased Conversion Price then in effect 
following such adjustment.

         (h)  The Issuer reserves the right to make such reductions in the 
Conversion Price in addition to those required in the foregoing provisions as 
it considers to be advisable in order that any event treated for Federal 
income tax purposes as a dividend of stock or stock rights will not be 
taxable to the recipients.  In the event the Issuer elects to make such a 
reduction in the Conversion Price, the Issuer will comply with the 
requirements of Rule 14e-1 under the 1934 Act, and any other securities laws 
and regulations thereunder if and to the extent that such laws and 
regulations are applicable in connection with the reduction of the Conversion 
Price.

    4.4  In the event the Issuer distributes rights or warrants (other than 
those referred to in Section 4.3(a)(ii)) pro rata to all Holders of shares of 
any class of Common Stock, so long as any such rights or warrants have not 
expired or been redeemed by the Issuer, the Holder of any Series C Preferred 
Stock surrendered for conversion will, in the discretion of the Issuer and 
subject to the last paragraph of this Section 4.4, be entitled to receive 
upon such conversion, in addition to the shares of Common Stock then issuable 
upon such conversion (the "Conversion Shares"), a number of rights or 
warrants to be determined as follows:  

         (a)  if such conversion occurs on or prior to the date for the 
distribution to the Holders of rights or warrants of separate certificates 
evidencing such rights or warrants (the "Distribution Date"), the same number 
of rights or warrants to which a Holder of a 

                                     -13-


number of shares of Common Stock equal to the number of Conversion Shares is 
entitled at the time of such conversion in accordance with the terms and 
provisions applicable to the rights or warrants, and

         (b)  if such conversion occurs after such Distribution Date, the 
same number of rights or warrants to which a Holder of the number of shares 
of common stock of EchoStar into which such Series C Preferred Stock was 
convertible immediately prior to such Distribution Date would have been 
entitled on such Distribution Date in accordance with the terms and 
provisions of and applicable to the rights or warrants.  

    In the event the Holders of the Series C Preferred Stock are not entitled 
to receive such rights or warrants pursuant to Section 4.4(a) or 4.4(b), the 
Conversion Price will be subject to adjustment upon any declaration or 
distribution of such rights or warrants pursuant to Section 4.3, above.

    4.5(a)  In case of:

         (i) any capital reorganization or reclassification or other change of
    outstanding 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 

         (ii) any consolidation or merger of the Issuer with or into another
    Person (other than a consolidation or merger in which the Issuer is the
    resulting or surviving Person and which does not result in any
    reclassification or change of outstanding Class A Common Stock), or 

         (iii) any sale or other disposition to another Person of all or
    substantially all of the assets of the Issuer (other than the sale,
    transfer, assignment or distribution of shares of capital stock or assets
    to a Subsidiary) 

(any of the events described in Section 4.5(a) being referred to in this 
Section 4.5 as a "Transaction"), then the adjustment described in Section 
4.5(b) will be made.

         (b) Each share of Series C Preferred Stock then outstanding shall, 
without the consent of any Holder of Series C Preferred Stock, become 
convertible only into the kind and amount of shares of stock or other 
securities (of the Issuer or another issuer) or property or cash receivable 
upon such Transaction by a Holder of the number of shares of Class A Common 
Stock into which such share of Series C Preferred Stock could have been 
converted immediately prior to such Transaction after giving effect to any 
adjustment event.  

                                     -14-


         (c) The provisions of this Section 4.5 and any equivalent thereof in 
any such certificate similarly shall apply to successive Transactions.  The 
provisions of this Section 4.5 shall be the sole right of Holders of Series C 
Preferred Stock in connection with any Transaction and such Holders shall 
have no separate vote thereon.

    4.6  In the case of any distribution by the Issuer to its stockholders of 
substantially all of its assets, each Holder of Series C Preferred Stock will 
participate PRO RATA in such distribution based on the number of shares of 
Class A Common Stock into which such Holders' shares of Series C Preferred 
Stock would have been convertible immediately prior to such distribution.

    4.7  If, as a result of any Conversion Price Adjustment Event, a Holder 
of the Series C Preferred Stock becomes entitled to receive upon conversion 
shares of two or more classes of Capital Stock, the Issuer shall determine 
the reasonable allocation of the adjusted Conversion Price between the 
classes of Capital Stock.  After such allocation, the Conversion Price of 
each class of Capital Stock shall thereafter be subject to adjustment on 
terms comparable to the Series C Preferred Stock in this Article 4.

    4.8  The Issuer shall at all times reserve and keep available for 
issuance upon the conversion of the Series C Preferred Stock, such number of 
its authorized but unissued shares of Class A Common Stock as will from time 
to time be sufficient to permit the conversion of all outstanding shares of 
Series C Preferred Stock, and shall take all action required to increase the 
authorized number of shares of Class A Common Stock if at any time there 
shall be insufficient authorized but unissued shares of Class A Common Stock 
to permit such reservation or to permit the conversion of all outstanding 
shares of Series C Preferred Stock.

    4.9  The issuance or delivery of certificates for Class A Common Stock 
upon the conversion of shares of Series C Preferred Stock shall be made 
without charge to the converting Holder of shares of Series C Preferred Stock 
for such certificates or for any tax in respect of the issuance or delivery 
of such certificates or the securities represented thereby, and such 
certificates shall be issued or delivered in the respective names of, or in 
such names as may be directed by, the Holders of the shares of Series C 
Preferred Stock converted; 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 and delivery of any such certificate in a name other 
than that of the Holder of the shares of Series C Preferred Stock converted, 
and the Issuer shall not be required to issue or deliver such certificate 
unless or until the Person or Persons requesting the issuance or delivery 
thereof shall have paid to the Issuer the amount of such tax or shall have 
established to the reasonable satisfaction of the Issuer that such tax has 
been paid.

                                     -15-


5   OPTIONAL REDEMPTION OF SERIES C PREFERRED STOCK

    5.1  (a) Shares of the Series C Preferred Stock will not be redeemable
prior to November 1, 2000.

         (b) After October 31, 2000, the Series C Preferred Stock may be 
redeemed, in whole or in part, at the option of the Issuer, in cash, by 
delivery of fully paid and nonassessable shares of Class A Common Stock or a 
combination thereof, upon not less than 20 days' notice nor more than 60 
days' notice, during the twelve-month periods commencing on November 1 of the 
years indicated below, at the following Redemption Prices per share, plus in 
each case all accumulated and unpaid dividends to the Redemption Date:

     YEAR                                                    REDEMPTION
     ----                                                 PRICE PER SHARE
                                                          ---------------
     2000 ...............................................     $51.929    
     2001 ...............................................     $51.447    
     2002 ...............................................     $50.965

     2004 and thereafter  ...............................     $50.000   
     --------------------------------------------------------------------
     --------------------------------------------------------------------

         (c)  In the event that fewer than all the outstanding shares of the 
Series C Preferred Stock are to be redeemed, the shares to be redeemed will 
be determined pro rata or by lot.

         (d)  If the Issuer elects to pay the Redemption Price in shares of 
Class A Common Stock, the number of shares of Class A Common Stock to be 
distributed will be calculated by dividing the aggregate Redemption Price 
payable to any Holder by 95% of the Market Value as of the Redemption Notice 
Date.

         (e)  From and after the applicable Redemption Date (unless the 
Issuer shall be in default of payment of the Redemption Price), dividends on 
the shares of the Series C Preferred Stock to be redeemed on such Redemption 
Date shall cease to accumulate, such shares shall no longer be deemed to be 
outstanding, and all rights of the Holders thereof as stockholders of the 
Issuer (except the right to receive the Redemption Price) will cease.

                                     -16-



    5.2  If any dividends on the Series C Preferred Stock are in arrears, no
shares of the Series C Preferred Stock will be redeemed unless all outstanding
shares of the Series C Preferred Stock are simultaneously redeemed.

    5.3  In the event the Issuer shall elect to redeem shares of the Series C
Preferred Stock pursuant to Section 5.1 hereof, the Issuer must provide the
Holders with the Redemption Notice as described in Section 5.1(b), and:

         (a)   (i) On or before any Redemption Date, each Holder of shares of
    Series C Preferred Stock to be redeemed shall surrender the certificate or
    certificates representing such shares of Series C Preferred Stock (properly
    endorsed or assigned for transfer, if the Issuer shall so require and the
    Redemption Notice shall so state), to the Issuer or the Redemption Agent
    (if appointed) in the manner and at the place designated in the Redemption
    Notice.

         (ii)  On the first Business Day following the Redemption Date, the
    Issuer or the Redemption Agent, as applicable, shall pay or deliver to the
    Holder, whose name appears on such certificate or certificates as the owner
    thereof, the full Redemption Price due such Holder in cash, in fully paid
    and nonassessable shares of Class A Common Stock or in a combination
    thereof.  

         (iii) The shares represented by each certificate to be surrendered
    shall be automatically (and without any further action of the Issuer or the
    Holder) canceled as of the Redemption Date whether or not certificates for
    such shares are returned to the Issuer and returned to authorized but
    unissued shares of preferred stock of no series.

         (iv)  If fewer than all the shares represented by any such certificate
    are to be redeemed, a new certificate shall be issued representing the
    unredeemed shares, without costs to the Holder, together with the amount of
    cash, if any, in lieu of fractional shares to the extent the Issuer is
    legally and contractually entitled to pay cash for said fractional shares. 
    If the Issuer is not entitled to pay cash for fractional shares, it shall
    pay cash to the Holder for the fractional shares when it becomes legally
    and contractually able to pay such cash.

         (b)  If a Redemption Notice shall have been given as provided in
Section 5.1, dividends on the shares of Series C Preferred Stock so called for
redemption shall cease to accrue, such shares shall no longer be deemed to be
outstanding, and all rights of the Holders thereof as stockholders of the Issuer
with respect to shares so called for redemption (except for the right to receive
from the Issuer the Redemption Price) shall 


                                      -17-



cease (excluding any right to receive the dividend payment on shares called 
for redemption whether the Redemption Date falls between the Dividend Payment 
Record Date and the Dividend Payment Date) either (i) from and after the 
Redemption Date (unless the Issuer shall default in the payment of the 
Redemption Price, in which case such rights shall not terminate at such time 
and date) or (ii) if the Issuer shall so elect and state in the Redemption 
Notice, from and after the time and date (which date shall be the Redemption 
Date or an earlier date not less than 20 days after the date of mailing of 
the Redemption Notice) on which the Issuer shall irrevocably deposit in trust 
for the Holders of the shares to be redeemed with a designated Redemption 
Agent as paying agent sufficient to pay at the office of such paying agent, 
on the Redemption Date, the Redemption Price.  Any money or shares of Class A 
Common Stock so deposited with such Redemption Agent which shall not be 
required for such redemption shall be returned to the Issuer forthwith.  
Subject to applicable escheat laws, any moneys or shares of Class A Common 
Stock so set aside by the Issuer and unclaimed at the end of one year from 
the Redemption Date shall revert to the general funds of the Issuer, after 
which reversion the Holders of such shares so called for redemption shall 
look only to the general funds of the Issuer for the payment of the 
Redemption Price without interest. Any interest accrued on funds held by the 
Redemption Agent shall be paid to the Issuer from time to time.

         (c)  In the event that fewer than all the outstanding shares of the
Series C Preferred Stock are to be redeemed, the shares to be redeemed shall be
determined pro rata or by lot, as determined by the Issuer, except that the
Issuer may redeem such shares held by any Holder of fewer than 100 shares (or
shares held by Holders who would hold fewer than 100 shares as a result of such
redemption), as may be determined by the Issuer.

         (d)  If any Holder whose shares of Series C Preferred Stock are called
for redemption pursuant to this Article 5 fails to surrender the certificate
representing such shares (or fails to arrange for the appropriate book-entry
transfer if a global certificate has been issued), such Holder shall not be
entitled to receive payment of the redemption price until the certificate has
been surrendered for cancellation or the appropriate book-entry transfer is
made.  Such Holder will not be entitled to receive any interest on the
Redemption Price from the Redemption Date.


                                      -18-



6   CHANGE OF CONTROL

    6.1  (a) In the event of a Change of Control, Holders shall, if the Market
Value at such time is less than the Conversion Price, have a one time option,
upon not less than 30 days' notice nor more than 60 days' notice, to convert all
of their outstanding shares of Series C Preferred Stock into shares of Class A
Common Stock at an adjusted Conversion Price equal to the greater of:

         (i) the Market Value as of the Change of Control date and 

         (ii) $13.00.

         (b)  In lieu of issuing the shares of Class A Common Stock issuable
upon conversion in the event of a Change of Control, the Issuer may, at its
option, make a cash payment equal to the Market Value of such Class A Common
Stock otherwise issuable.

    6.2  The foregoing provision is not waivable by the Issuer.

7   LIQUIDATION PREFERENCE

    7.1  Upon any voluntary or involuntary liquidation, dissolution or
winding-up of the Issuer, Holders of the Series C Preferred Stock will be
entitled to be paid, out of assets of the Issuer available for distribution the
Liquidation Preference per share plus an amount in cash equal to all accumulated
and unpaid dividends thereon to the date fixed for liquidation, dissolution or
winding-up (including an amount equal to a prorated dividend for the period from
the last dividend payment date to the date fixed for liquidation, dissolution or
winding-up), before any distribution is made on any Junior Securities,
including, without limitation, the common stock.  

    7.2  If, upon any voluntary or involuntary liquidation, dissolution or
winding-up of the Issuer, the amounts payable with respect to the Series C
Preferred Stock and all other Parity Securities are not paid in full, the
Holders of the Series C Preferred Stock and the Parity Securities will share
equally and ratably in any distribution of assets of the Issuer in proportion to
the full Liquidation Preference and accumulated and unpaid dividends to which
each is entitled.  

    7.3  After payment of the full amount of the Liquidation Preference and
accumulated and unpaid dividends to which they are entitled, the Holders of
shares of the Series C Preferred Stock will not be entitled to any further
participation in any distribution of assets of the Issuer.  


                                      -19-



    7.4  Neither the sale, conveyance, exchange or transfer (for cash, shares
of stock, securities or other consideration) of all or substantially all of the
property or business of the Issuer (other than in connection with the winding up
of its business) nor the merger or consolidation of the Issuer with or into any
other corporation will be deemed to be a dissolution, liquidation, or
winding-up, voluntary or involuntary, of the Issuer.

8   VOTING RIGHTS

    8.1  Holders of the Series C Preferred Stock have no voting rights with
respect to general corporate matters except as provided by law or as set forth

    8.2  If dividends on the Series C Preferred Stock are in arrears and unpaid

separately as a class with the shares of any other preferred stock or preference
securities having similar voting rights will be entitled at the next regular or
special meeting of stockholders of the Issuer to elect two directors of the
Issuer.  Such voting rights will continue only until such time as the dividend
arrearage on the Series C Preferred Stock has been paid in full.

    8.3  The affirmative vote or consent of the Holders of at least 66-2/3% of
the outstanding Series C Preferred Stock will be required for:

         (a) the issuance of any class of Senior Securities or Parity Securities

Securities or Parity Securities) (other than additional shares of Series B
Preferred Stock or Parity Securities with an aggregate liquidation preference,
at any one time outstanding, not to exceed $100 million), and

         (b) amendments to the Issuer's Articles of Incorporation that would
affect adversely the rights of Holders of the Series C Preferred Stock,
including, without limitation, 

         (i) any increase in the authorized number of shares of Series C
    Preferred Stock and 

         (ii) the issuance of any shares of Series C Preferred Stock in excess
    of the number of shares of such stock authorized in this Certificate of
    Designation.  

In all such cases each share of Series C Preferred Stock shall be entitled to
one vote.

    8.4  Except as set forth in this Certificate of Designation,


                                      -20-

Securities, Parity Securities or Senior Securities or 

         (b) an increase or decrease in the amount of authorized capital stock
of any class, including any preferred stock, 

shall not require the consent of the Holders of the Series C Preferred Stock and
shall not be deemed to affect adversely the rights, preferences, privileges or
voting rights of Holders of shares of the Series C Preferred Stock.

    8.5  Any exercise of the voting rights contained herein will be subject to
applicable provisions of the Communications Act including, without limitation,
the requirements of prior approval for transfer of control or assignment of
Title III licenses (as that term is defined in the Communications Act).

9   NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES, INCORPORATORS AND
    STOCKHOLDERS.

    9.1  No director, officer, employee, incorporator or stockholder of the
Issuer or any of its Affiliates, as such, shall have any liability for any
obligations of the Issuer and any of its Affiliates under the Series C Preferred
Stock or the Certificate of Designation or for any claim based on, in respect
of, or by reason of, such obligations or their creation.  Each Holder of the
Series C Preferred Stock waives and releases all such liability.  The waiver and
release are part of the consideration for issuance of the Series C Preferred
Stock.

10  AMENDMENT, SUPPLEMENT AND WAIVER

    10.1 Without the consent of any Holder of the Series C Preferred Stock, the
Issuer may amend or supplement this Certificate of Designation to cure any

Stock, to provide for the assumption of the Issuer's obligations to Holders of
the Series C Preferred Stock in the case of a merger or consolidation, to make

rights under this Certificate of Designation of any such Holder.
