                       PURSUANT TO SECTION 78.1955 OF THE
                             Nevada Revised Statutes

         I, David K. Moskowitz, the Senior Vice President, General Counsel and
Secretary of EchoStar Communications Corporation (the "Issuer"), a corporation
organized and existing under the laws of the State of Nevada, do hereby certify
that pursuant to authority conferred upon the Board of Directors of the Issuer
by its Amended and Restated Articles of Incorporation and pursuant to the
provisions of Section 78.1955 of the Nevada Revised Statutes, the Issuer's Board
of Directors, on December 12, 2001, adopted the following resolution
establishing the Issuer's Series D Mandatorily Convertible Participating
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 Amended and Restated 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 "Series D Mandatorily Convertible Participating Preferred
         Stock" (referred to herein as the "Series D 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 D Preferred
         Stock are not stated and expressed in the Amended and Restated Articles
         of Incorporation, the powers, preferences and relative and other
         special rights and the qualifications, limitations and restrictions
         thereof, as follows:

ARTICLE 1 DESIGNATION AND NUMBER OF SHARES

         SECTION 1.1 The series will be known as the "Series D Mandatorily
Convertible Participating Preferred Stock".

         SECTION 1.2 The Series D Preferred Stock will be a series consisting of
5,760,479 shares of the authorized but unissued preferred stock of the Issuer.

<PAGE>

ARTICLE 2 DIVIDENDS AND DISTRIBUTIONS

         SECTION 2.1 The Holders of shares of Series D Preferred Stock shall be
entitled to receive, when and as declared by the Board of Directors, but only
out of funds legally available therefor, dividends or distributions on each date
that dividends or other distributions (including any distributions of Capital
Stock, evidences of indebtedness, other securities or any other assets) are
payable or distributable on or in respect of Class A Common Stock of the Issuer,
in an amount per whole share of Series D Preferred Stock equal to the aggregate
amount (in cash, securities or other property) of dividends or other
distributions that would be payable on such date to a Holder of that number of
shares of Common Stock into which one share of Series D Preferred Stock shall be
convertible at the Conversion Rate (defined below). Each such dividend or
distribution shall be paid to each Holder of record of shares of Series D
Preferred Stock on the record date, not exceeding sixty days preceding such
payment date, fixed for the purpose by the Board of Directors in advance of
payment of each particular dividend or distribution (which record date shall be
the same date as the record date for the corresponding payment of dividends or
distributions on the Class A Common Stock). Any share of Series D Preferred
Stock originally issued after a dividend or distribution record date and on or
prior to the dividend or distribution payment date to which such record date
relates shall not be entitled to receive the dividend or distribution payable on
such dividend or distribution payment date or any amount in respect of the
period from the date of such issuance to such dividend or distribution payment
date. Holders of shares of Series D Preferred Stock shall not be entitled to any
dividends or distributions, whether payable or distributable in cash, property
or stock, in excess of full dividends or distributions as herein provided.

         SECTION 2.2 So long as any shares of Series D Preferred Stock shall be
outstanding, no dividend shall be declared or paid or set aside for payment or
other distribution declared or made upon the Common Stock or upon any other
stock ranking junior to the Series D Preferred Stock as to dividends or
distribution of assets upon Liquidation, nor shall any Common Stock nor any
other stock of the Issuer ranking junior to or on a parity with the Series D
Preferred Stock as to dividends or distribution of assets upon Liquidation be
redeemed, purchased or otherwise acquired for any consideration (or any monies
be paid to, set aside or made available for a sinking fund for the redemption of
any shares of any such stock) by the Issuer (except by conversion into or
exchange for stock of the Issuer ranking junior to the Series D Preferred Stock
as to distribution of assets upon Liquidation), unless, in each case, the full
dividends (including the dividend to be due upon payment of such dividend,
distribution, redemption, purchase or other acquisition) on all outstanding
shares of Series D Preferred Stock shall have been, or shall then be, paid.

ARTICLE 3 RANKING

         The preferences of each share of Series D Preferred Stock as to
distribution of assets upon Liquidation shall be in every respect on a parity
with the preferences of every

                                       2
<PAGE>

other share of capital stock of the Issuer which is not specifically made senior
or junior to the Series D Preferred Stock as to distribution of assets upon
Liquidation. The rights of the Common Stock will be junior to the Series D
Preferred stock as to distributions upon Liquidation to the extent herein
provided.

ARTICLE 4 OPTIONAL CONVERSION AND CONVERSION PROCEDURES

         SECTION 4.1 (a) Each Holder of Series D 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 Article 4, any or all of such Holder's shares
of Series D Preferred Stock. In such case, each whole share of Series D
Preferred Stock shall be converted into ten (10) fully paid and nonassessable
shares of Class A Common Stock (the "Conversion Rate").

                  (b) The conversion right of a Holder of Series D 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.

                  (i) Immediately prior to the close of business on the
         Conversion Date, each converting Holder of Series D Preferred Stock
         shall be deemed to be the Holder of record of Class A Common Stock
         issuable upon conversion of such Holder's Series D 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 D
         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 D 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 D Preferred
         Stock have been converted; (2) the payment in cash or shares of Class A
         Common Stock of any declared and unpaid dividends and distributions
         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.

         SECTION 4.2 (a) When shares of Series D Preferred Stock are converted
pursuant to this Article 4, any declared and unpaid dividends and distributions
on the Series D Preferred

                                       3
<PAGE>

Stock so converted to which the Holder of such Series D Preferred Stock is
entitled in accordance with Section 2.1 hereof, to (but not including) the
Conversion Date, shall be due and payable, at the Issuer's option,

                  (i) in cash;

                  (ii) in a number of fully paid and nonassessable shares of
         Class A Common Stock equal to the quotient obtained by dividing (A) the
         amount of declared and unpaid dividends payable to the Holder of Series
         D Preferred Stock so converted by (B) 95% of the current market price,
         determined in accordance with subsection (b) below, on the Conversion
         Date; or

                  (iii) a combination thereof.

                  (b) The current market price per share of Class A Common Stock
on any date shall be deemed to be the average of the Daily Market Prices for the
ten (10) consecutive trading days ending on the last full trading day on the
exchange or market referred to in determining such Daily Market Prices prior to
the time of determination.

                  (c) No payment or adjustment shall be made by the Issuer upon
any conversion of Series D Preferred Stock on account of any dividends or
distributions on the Class A Common Stock or other securities issued upon
conversion.

         SECTION 4.3 (a) In case the Issuer shall (i) subdivide its outstanding
shares of Common Stock into a greater number of shares of Common Stock or (ii)
combine its outstanding shares of Common Stock into a smaller number of shares
of Common Stock, the Issuer shall effect the same subdivision, combination or
similar change with respect to the Series D Preferred Stock of the Issuer as is
made with respect to the Common Stock such that the Holder of any share of
Series D Preferred Stock thereafter surrendered for conversion shall be entitled
to receive the number of shares of Common Stock which such Holder would have
owned immediately following such action had such shares of Series D Preferred
Stock been converted immediately prior thereto. Any adjustment made pursuant to
this subsection (a) shall become effective immediately 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) Except as permitted in Article 6 with respect to a Change
of Control Transaction, in case of any consolidation of the Issuer with, or
merger of the Issuer into, any other Person, or any merger of another Person
into the Issuer, or any statutory exchange of securities with another
corporation (including any exchange effected in connection with a merger of a
third corporation into the Issuer), or any sale, conveyance or transfer of all
or substantially all of the assets of the Issuer (in each case other than any
such consolidation, merger, statutory exchange, sale, conveyance or transfer
that does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock), appropriate provision shall
be made in the agreement governing any such consolidation, merger, statutory
exchange, sale, conveyance or transfer so that the holder of each share of
Series D Preferred Stock

                                       4
<PAGE>

outstanding immediately prior to the consummation of such consolidation, merger,
statutory exchange, sale, conveyance or transfer shall have the right thereafter
to convert such share into the kind and amount of securities, cash or other
property receivable upon such consolidation, merger, statutory exchange, sale,
conveyance or transfer by a Holder of the number of shares of Class A Common
Stock into which such share of Series D Preferred Stock might have been
converted immediately prior to such consolidation, merger or statutory exchange,
assuming such Holder of Class A Common Stock failed to exercise his rights of
election, if any, as to the kind or amount of securities, cash or other property
receivable upon such consolidation, merger, statutory exchange, sale, conveyance
or transfer (provided that if the kind or amount of securities, cash or other
property receivable upon such consolidation, merger, statutory exchange, sale,
conveyance or transfer is not the same for each share of Class A Common Stock in
respect of which such rights of election shall not have been exercised
("non-electing share"), then for the purpose of this subsection (b) the kind and
amount of securities, cash or other property receivable upon such consolidation,
merger, statutory exchange, sale, conveyance or transfer for each non-electing
share shall be deemed to be the kind and amount so receivable per share by a
plurality of the non-electing shares). Thereafter, the holders of the Series D
Preferred Stock shall be entitled to appropriate adjustments with respect to
their conversion rights to the end that the provisions set forth in this Section
4.3 shall correspondingly be made applicable, as nearly equivalent as
practicable, in relation to any shares of stock or other securities or other
property thereafter deliverable on the conversion of the Series D Preferred
Stock. The provisions of this subsection (b) shall similarly apply to successive
consolidations, mergers or statutory exchanges. The provisions of this
subsection (b) shall not apply to the Merger or any of the other transactions or
actions provided for by the Transaction Agreements (as such term is defined in
the Implementation Agreement).

         SECTION 4.4 The Issuer shall at all times reserve and keep available
for issuance upon the conversion of the Series D 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
D 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
D Preferred Stock.

         SECTION 4.5 The issuance or delivery of certificates for Class A Common
Stock upon the conversion of shares of Series D Preferred Stock shall be made
without charge to the converting Holder of shares of Series D 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 D 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

                                       5
<PAGE>

Series D 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 or is not payable.

ARTICLE 5 MANDATORY CONVERSION

         SECTION 5.1 (a) Subject to Section 5.1(b), each share of Series D
Preferred Stock shall be automatically converted into ten (10) fully paid and
nonassessable shares of Class A Common Stock, upon the occurrence of any of the
following events or dates (each, a "Conversion Trigger Event"), without any
action on the part of any Holder:

                  (i) the effective time of the Merger provided for in Article I
         of the Merger Agreement;

                  (ii) on the first date that the sum of (A) the number of
         shares of Class A Common Stock into which the shares of Series D
         Preferred Stock then held of record and beneficially by the Initial
         Holder are convertible on such date and (B) the number of shares of
         Class A Common Stock, if any, theretofore received by the Initial
         Holder upon conversion of shares of Series D Preferred Stock, for which
         shares of Class A Common Stock the Initial Holder shall continue to be
         the record and beneficial owner as of the date of any determination
         under this clause (ii), shall cease to constitute 51% or more of the
         aggregate number of shares of Class A Common Stock into which the
         shares of Series D Preferred Stock issued to the Initial Holder on the
         Issuance Date were convertible into on such date (as such aggregate
         number may be adjusted from time to time as necessary to reflect
         appropriately any stock splits, subdivisions, combinations and similar
         changes to the Capital Stock of the Issuer);

                  (iii) the purported sale, assignment, transfer or other
         disposition of a share of Series D Preferred Stock or beneficial
         ownership thereof by the Initial Holder to any Person other than a
         Permitted Transferee; or

                  (iv) January 22, 2007;

unless such share of Series D Preferred Stock shall have earlier have been
converted in accordance with Article 4 hereof or this Article 5. For purposes of
this Section 5.1 and Section 13.2, the terms "beneficial owner" and
"beneficially" shall be construed in accordance with Rule 13d-3 under the
Exchange Act.

                  (b) Any such conversion pursuant to Section 5.1(a) shall be
effected (i) in the case of the Conversion Trigger Event in clause (i) of
Section 5.1(a), immediately prior to the effective time of the Merger; (ii) in
the case of the Conversion Trigger Event in clause (ii) or (iv) thereof, on the
date specified therein, and (iii) in the case of the Conversion Trigger Event in
clause (iii) thereof, immediately prior to such sale, transfer or other
disposition. Any conversion effected pursuant to clause (iii) of Section 5.1(a)
shall apply only to such share or shares of Series D Preferred Stock as are so
sold, transferred or otherwise disposed of. Any conversion pursuant to clause
(ii) or (iii) of

                                       6
<PAGE>

Section 5.1(a) shall become effective notwithstanding any failure by the Initial
Holder to notify the Issuer of any change in ownership pursuant to Section 13.2
hereof.

                  (c) For purposes of this Section 5.1, the "Initial Holder"
shall be deemed to include any Permitted Transferee of the Initial Holder which
is then a Holder of any shares of Series D Preferred Stock.

         SECTION 5.2 (a) Upon notice from the Issuer, each Holder of Series D
Preferred Stock converted in accordance with Section 5.1 hereof 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.

                  (b) Upon any conversion of shares of Series D Preferred Stock
in accordance with Section 5.1 hereof, all rights with respect to the shares of
Series D Preferred Stock so converted, including the rights of a Holder, if any,
to receive notices, will terminate, except the rights of Holders thereof to: (i)
receive certificates for the number of shares of Class A Common Stock into which
such shares of Series D Preferred Stock have been converted; (ii) the payment in
cash or shares of Class A Common Stock of any declared and unpaid dividends and
distributions accrued thereon to (but not including) the date of such conversion
pursuant to Section 4.2 hereof; and (iii) exercise the rights to which they are
entitled as Holders of Class A Common Stock.

ARTICLE 6 CHANGE OF CONTROL

         SECTION 6.1 (a) Without limiting the rights of Holders of shares of
Series D Preferred Stock pursuant to Article 4, in the event that a Change of
Control Transaction shall occur, the Holders shall be entitled to be paid in
full, to the extent of funds legally available therefor, an amount in cash per
share of Series D Preferred Stock equal to the Liquidation Preference, plus any
declared and unpaid dividends accrued thereon to (but not including) the Change
in Control Date (as defined in Section 6.1(d)).

                  (b) If the Surviving Corporation, if any, resulting from any
Change of Control Transaction shall be a Person other than the Issuer, the
Surviving Corporation shall execute and deliver an agreement for the benefit of
the Holders of the Series D Preferred Stock providing that each Holder of
outstanding shares of Series D Preferred Stock immediately prior to the Change
of Control Transaction shall thereafter have the right to demand payment from
the Surviving Corporation of the amounts payable to such Holder pursuant to
Section 6.1(a), with respect to such Holder's shares of Series D Preferred
Stock.

                  (c) Immediately prior to the consummation of a Change in
Control Transaction, all shares of Series D Preferred Stock shall cease to be
outstanding, the Holders thereof shall cease to be stockholders with respect to
such shares and all rights

                                       7
<PAGE>

with respect to such shares of Series D Preferred Stock, including the rights of
a Holder, if any, to convert such shares and to receive notices, will terminate,
except the rights of a Holder thereof to receive payment of the amount due to
such Holder pursuant to Section 6.1(a) with respect to such Holder's shares of
Series D Preferred Stock.

                  (d) Upon notice from the Issuer (or the Surviving Corporation,
if applicable) of the occurrence of a Change in Control Transaction, which
notice shall include the date on which the Change in Control Transaction
occurred (the "Change of Control Date") and the amount per share of Series D
Preferred Stock outstanding immediately prior to such Change in Control
Transaction payable pursuant to Section 6.1(a), each Holder of Series D
Preferred Stock shall promptly surrender to the Issuer or the Transfer Agent the
certificates formerly representing such Series D Preferred Stock (if not
previously delivered), duly endorsed in blank or accompanied by proper
instruments of transfer, and the Issuer or the Surviving Corporation, as the
case may be, shall pay to the surrendering Holder promptly after such surrender
all amounts payable in respect of the shares of Series D Preferred Stock
represented by such surrendered certificate.

ARTICLE 7 LIQUIDATION

         SECTION 7.1 In the event of any Liquidation the Holders of shares of
Series D Preferred Stock shall be entitled, before any distribution or payment
is made on any date to the Holders of the Common Stock or any other stock of the
Issuer ranking junior to the Series D Preferred Stock as to distribution of
assets upon Liquidation, to be paid in full the greater of (i) an amount per
share of Series D Preferred Stock equal to the Liquidation Preference, plus any
declared and unpaid dividends thereon from the date fixed for payment of such
dividends to the date fixed for Liquidation and (ii) an amount per share of
Common Stock to which such Holders of shares of Series D Preferred Stock would
have been entitled upon Liquidation if such Holders had converted such shares of
Series D Preferred Stock into Class A Common Stock immediately prior to the date
fixed for Liquidation. If such payment shall have been made in full to all
Holders of shares of Series D Preferred Stock, then the Holders of shares of
Series D Preferred Stock as such shall have no right or claim to any of the
remaining assets of the Issuer.

         SECTION 7.2 If the assets of the Issuer available for distribution to
the Holders of shares of Series D Preferred Stock upon any Liquidation shall be
insufficient to pay in full all amounts to which such Holders shall be entitled
pursuant to Section 7.1, no such distribution shall be made on account of any
shares of any other class or series of Preferred Stock ranking on a parity with
the Series D Preferred Stock as to distribution of assets upon Liquidation
unless proportionate distributive amounts shall be paid on account of all
outstanding shares of Series D Preferred Stock, ratably in proportion to the
full distributable amounts for which Holders of all such parity shares are
respectively entitled upon such Liquidation.

incorporation of the Issuer, the Holders of Series D Preferred Stock shall have
no voting rights other than such voting rights as are expressly provided in
Sections 8.2, 8.3 and 8.4.

         SECTION 8.2 A Holder of Series D Preferred Stock shall be entitled to
vote on any matter on which the Holders of Class A Common Stock are entitled to
vote. With respect to any such matter, each Holder of Series D Preferred Stock
shall be entitled to one vote for each whole share of Class A Common Stock that
would be issuable to such Holder upon the conversion of all the shares of Series
D Preferred Stock held by such Holder on the record date for the determination
of stockholders entitled to vote and, subject to Sections 8.3 and 8.4, the
Holders of Series D Preferred Stock shall vote together as a single class with
