                                    CONTINGENT VALUE RIGHTS AGREEMENT (this
                           "Agreement") dated as of January 22, 2002, between
                           ECHOSTAR COMMUNICATIONS CORPORATION, a Nevada
                           corporation (the "Company"), and VIVENDI UNIVERSAL,
                           S.A., a societe anonyme organized under the laws of
                           France (the "Investor").

                  WHEREAS, pursuant to the Investment Agreement dated as of
December 14, 2001 (the "Investment Agreement"), between the Company and the
Investor, and as a condition to the willingness of the Investor to enter into
the Investment Agreement, the Company has agreed to issue and deliver to the
Investor, upon consummation of the transactions contemplated by the Investment
Agreement, one contingent value right having the terms set forth in this
Agreement (the "CVRs") for each share of Class A common stock, par value $0.01
per share, of the Company ("Class A Common Stock", which term shall include any
class of capital stock of the Company into which the Class A Common Stock may be
reclassified, converted or exchanged as contemplated by Section 1.06) issuable
upon the conversion of shares of Series D mandatorily convertible participating
preferred stock, par value $0.01 per share, of the Company (the "Preferred
Stock") purchased by the Investor pursuant to the Investment Agreement;

                  WHEREAS the Company has duly authorized the creation and issue
of the CVRs, and to provide therefor the Company has duly authorized the
execution and delivery of this Agreement; and

                  WHEREAS, all things necessary have been done to make the CVRs
the valid obligations of the Company and to make this Agreement a valid
agreement of the Company, in each case in accordance with the terms of this
Agreement.

                  NOW, THEREFORE, in consideration of the premises and the
consummation of the transactions contemplated by this Agreement and the
Investment Agreement and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:

                                   ARTICLE I

                                Terms of the CVRs

                  SECTION 1.01. Issuance and Delivery of the CVRs; Form of CVRs.
Effective upon the consummation of the issuance, sale and delivery of the
Preferred Stock to the Investor pursuant to the Investment Agreement, there
shall be issued and delivered to the Investor pursuant to this Agreement,
without any further action on the part of the Company or the Investor, that
number of CVRs as is equal to the number of shares of Class A Common Stock into
which the Preferred Stock is convertible as of the closing date of the purchase
and sale pursuant to the Investment Agreement (the "Initial CVR Amount"). The
CVRs shall be in uncertificated form and shall be evidenced by Schedule I
hereto, and the number of CVRs initially indicated on Schedule I shall be equal
to the Initial CVR Amount. The number of CVRs indicated on Schedule I as being
outstanding and owned by the Investor or its wholly owned




                                                                               2


subsidiaries shall be adjusted from time to time (i) in accordance with Section
1.04, based on sales of Class A Common Stock by the Investor or its wholly owned
subsidiaries and (ii) pursuant to the provisions of Section 1.06. The number of
CVRs indicated on Schedule I shall be considered to be "held" by the Investor or
its wholly owned subsidiary and "outstanding", notwithstanding the fact that the
CVRs are in uncertificated form.

                  The Company acknowledges that pursuant to Section 7.01(a) of
the Investment Agreement, the Investor has assigned the right to receive the
CVRs to Financiere De Videocommunication, its indirect wholly owned subsidiary.

                  SECTION 1.02. Maturity Date; CVR Payment Calculation. The
Company shall pay to the Investor on the date (the "Maturity Date") that is the
earliest to occur of:

                  (i) 36 months following the consummation of the merger (the
         "Merger") provided for in Article I of the Agreement and Plan of Merger
         dated as of October 28, 2001, by and between the Company and Hughes
         Electronics Corporation, a Delaware corporation ("Hughes"), as amended
         as of the date of this Agreement (as it may be amended from time to
         time, the "Merger Agreement");

                  (ii) 30 months following the acquisition by the Company of all
         of Hughes's indirect equity interests in PanAmSat Corporation, a
         Delaware corporation ("PanAmSat"), pursuant to the terms of the Stock
         Purchase Agreement dated as of October 28, 2001, among the Company,
         Hughes, Hughes Communications Galaxy, Inc., Hughes Communications
         Satellite Services, Inc. and Hughes Communications, Inc. (as it may be
         amended from time to time, the "PanAmSat Stock Purchase Agreement"); or

                  (iii) 30 months following the termination of the Merger
         Agreement and the termination of the PanAmSat Stock Purchase Agreement
         (with (a) any termination of the PanAmSat Stock Purchase Agreement by
         the Company upon written notice to the other parties thereto in
         accordance with the terms thereof being deemed a termination thereof,
         (b) any termination of the PanAmSat Stock Purchase Agreement by mutual
         agreement of Hughes and the Company in accordance with the terms
         thereof being deemed a termination thereof and (c) any purported
         termination of the PanAmSat Stock Purchase Agreement by Hughes upon
         written notice to the Company in accordance with the terms thereof
         being deemed a termination thereof, unless as promptly as practicable
         after the Company's receipt of Hughes's notice purporting to terminate
         the PanAmSat Stock Purchase Agreement, the Company notifies Hughes in
         writing that it objects to such purported termination, in which case
         such purported termination shall not be deemed a termination of the
         PanAmSat Stock Purchase Agreement hereunder until the earliest to occur
         of (1) the date on which Company notifies Hughes in writing that the
         Company is no longer contesting such purported termination, (2) the
         date on which a court of competent jurisdiction issues a final,
         non-appealable order to the effect that Hughes's purported termination
         was in accordance with the terms of the PanAmSat Stock Purchase
         Agreement and (3) the date that is 30 months after the date of Hughes's
         written notice purporting to terminate the PanAmSat Stock Purchase
         Agreement)




                                                                               3



(such 30- or 36-month period, as applicable, being referred to as the
"Protection Period"), for each outstanding CVR held by the Investor and its
wholly owned subsidiaries on the Maturity Date, the amount (payable as set forth
in Section 1.07), if any, as determined by the Company, by which (x) the
Reference Price (as defined below) exceeds (y) the Volume Weighted Average Price
(as defined below) of Class A Common Stock for the 20 trading days ended five
trading days prior to the Maturity Date (the "20-Day Average Price"); provided,
however, that the maximum payment in respect of each CVR shall be (i) if on or
prior to the Maturity Date, the Merger has been consummated, an amount equal to
15% of the Reference Price and (ii) if on the Maturity Date, the Merger has not
been consummated, an amount equal to 35% of the Reference Price (such 15% amount
or 35% amount, as applicable, the "Payment Cap"), and, upon the payment in full
of any such amount, all of the CVRs then outstanding and this Agreement shall
thereupon automatically terminate and become null and void without any further
action on the part of any party hereto, and the holders thereof and the parties
hereto shall have no further rights with respect thereto or hereto. Such
determination by the Company absent manifest error shall be final and binding on
the Company and the Investor. The term "Reference Price" shall mean $26.0395,
which amount shall be subject to adjustment from time to time as set forth in
Section 1.06, and all references in this Agreement, whether or not expressly so
stated, shall be to the Reference Price then in effect. The term "Volume
Weighted Average Price" shall mean, with respect to the Class A Common Stock on
any trading day, the volume weighted average price per share for the regular
trading session (defined as 9:30 a.m. through 4:00 p.m., Eastern Time) during
such trading day, as published by Bloomberg (or its successor corporation) on
page "AQR" (or its successor page), or if not published by Bloomberg (or its
successor corporation), on such national securities market or exchange upon
which the volume weighted average price per share for the Class A Common Stock
is reported for such trading day, or if the volume weighted average price per
share for the Class A Common Stock is not reported on a national securities
market or exchange for such trading day, as determined in good faith by the
board of directors of the Company.

                  SECTION 1.03. Roll-Over of the CVRs Upon Consummation of the
Merger; Change of Control Transactions During the Protection Period. (a)
Roll-Over Upon Merger. Upon consummation of the Merger, this Agreement and the
CVRs shall become obligations of the surviving corporation in the Merger (the
"Surviving Corporation"), and at all times thereafter all references herein (i)
to Class A Common Stock, shall be deemed to be references to the Class A common
stock, par value $0.01 per share, of the Surviving Corporation into which each
share of Class A Common Stock shall be converted at the effective time of the
Merger and (ii) to the Company, shall be to the Surviving Corporation.

                  (b) Change of Control Transactions; Acceleration Election. If
         at any time during the Protection Period the Company proposes to enter
         into a Change of Control Transaction (as defined below), the Company
         shall, as soon as practicable following the first public disclosure of
         such Change of Control Transaction but in no event less than five
         business days prior to the consummation thereof (or such lesser period
         as the Company has knowledge of the proposed consummation), provide
         written notice to the Investor of its intention to enter into such
         Change of Control Transaction, which notice shall specify the date on
         which such Change of Control Transaction is expected to be consummated.
         If the Investor so elects by providing written notice (an "Acceleration
         Election") to the Company no more than two business days prior to the
         expected date of



                                                                               4


         consummation of such Change of Control Transaction (as specified in the
         Company's notice to the Investor), the Company shall pay to the
         Investor on the date of consummation of such Change of Control
         Transaction (the "Change of Control Date"), for each outstanding CVR
         held by the Investor and its wholly owned subsidiaries on the Change of
         Control Date, the amount (payable as set forth in Section 1.07), if
         any, as determined by the Company, by which (x) the Reference Price
         exceeds (y) the 20-Day Average Price (with the 20-Day Average Price
         calculated as if the Change of Control Date were the Maturity Date),
         subject to the Payment Cap, and, upon the payment in full of any such
         amount, all of the CVRs then outstanding and this Agreement shall
         thereupon automatically terminate and become null and void without any
         further action on the part of any party hereto, and the holders thereof
         and the parties hereto shall have no further rights with respect
         thereto or hereto. Such determination by the Company absent manifest
         error shall be final and binding on the Company and the Investor. If
         the Investor does not make an Acceleration Election, the terms of
         Article IV shall, if applicable, apply by their terms to such Change of
         Control Transaction. The term "Change of Control Transaction" shall
         mean any merger, consolidation, tender offer, statutory share exchange
         or sale, lease or transfer of all or substantially all of the Company's
         assets or similar transaction or group of related transactions, in each
         case to which the Company is a party (or, in the case of a tender
         offer, in which capital stock of the Company is the subject security),
         the consummation of which results in a Change of Control (as defined
         below); provided that (a) neither the Merger nor any of the
         transactions provided for by the Merger Agreement or the other
         Transaction Agreements (as such term is defined in the Implementation
         Agreement dated as of October 28, 2001, among the Company, Hughes and
         General Motors Corporation, a Delaware corporation, as amended as of
         the date of this Agreement and as it may be amended from time to time),
         shall constitute a Change of Control Transaction; and (b) the
         consummation of the transactions contemplated by the PanAmSat Stock
         Purchase Agreement, including any issuance of shares of Class A Common
         Stock in connection therewith, shall not constitute a Change of Control
         Transaction. The term "Change of Control" shall mean (a) any
         transaction or series of related transactions (including a tender
         offer, merger or consolidation) the result of which is that holders of
         outstanding voting capital stock of the Company immediately prior to
         such transaction or series of related transactions hold, directly or
         indirectly, capital stock of the surviving person in such transaction
         or series of related transactions (or any ultimate parent thereof)
         representing less than 50% of the voting power in the election of
         members of the board of directors (or comparable governing body) of all
         outstanding capital stock of such surviving person (or such ultimate
         parent) immediately after such transaction or series of related
         transactions; or (b) the sale, lease or transfer of all or
         substantially all of the Company's assets to any "person" or "group",
         within the meaning of Section 13(d)(3) and 14(d)(2) of the Securities
         Exchange Act of 1934, as amended (the "Exchange Act"), or any successor
         provision to either of the foregoing, including any group acting for
         the purpose of acquiring, holding or disposing of securities within the
         meaning of Rule 13d-5(b)(1) under the Exchange Act, other than to any
         subsidiary or subsidiaries of the Company.



                                                                               5


                  SECTION 1.04. CVRs Not Transferable. The CVRs shall not be
transferable other than from the Investor to a wholly owned subsidiary of the
Investor or from a wholly owned subsidiary of the Investor to the Investor or
another wholly owned subsidiary of the Investor. Upon the sale, transfer or
other disposition by the Investor or a wholly owned subsidiary of the Investor
(other than to the Investor or a wholly owned subsidiary of the Investor) of any
shares of Class A Common Stock that were issued upon the conversion of shares of
Preferred Stock or upon consummation of the Merger, that number of CVRs as is
equal to the number of shares of Class A Common Stock so sold, transferred or
otherwise disposed of shall thereupon automatically terminate and become null
and void, and the Investor (or such wholly owned subsidiary) shall have no
further rights with respect thereto.

                  SECTION 1.05. Early Termination of CVRs. If the Volume
Weighted Average Price of the Class A Common Stock exceeds 120% of the Reference
Price on each trading day for 90 consecutive calendar days (x) if the event the
occurrence of which caused the Protection Period to commence was the
consummation of the Merger in accordance with Section 1.02(i), at any time
during the 30-month period beginning on the date that is six months after the
date on which the Merger was consummated and ending on the Maturity Date and (y)
if the commencement of the Protection Period was caused by the occurrence of the
events listed in either Section 1.02(ii) or Section 1.02(iii), at any time
during the Protection Period, in either such case all of the CVRs then
outstanding and this Agreement shall thereupon automatically terminate and
become null and void without any further action on the part of any party hereto,
and the holders thereof and the parties hereto shall have no further rights with
respect thereto or hereto.

                  SECTION 1.06. Antidilution. If the Company shall at any time
(whether before or after consummation of the Merger) in any manner subdivide (by
stock split, stock dividend or otherwise) or combine (by reverse stock split or
otherwise) the number of outstanding shares of Class A Common Stock or effect a
merger, consolidation, statutory share exchange or other similar transaction in
which shares of Class A Common Stock are reclassified, converted into or
exchanged for a different number of shares of Class A Common Stock or shares of
capital stock of a different class, the number of outstanding CVRs shall
thereupon automatically be similarly subdivided, combined or changed and the
Reference Price shall thereupon automatically be appropriately adjusted (in the
case of a merger, consolidation, statutory share exchange or other similar
transaction, based on the relevant exchange ratio). Upon consummation of the
Merger, the number of outstanding CVRs and the Reference Price will
automatically be adjusted to reflect the exchange of Class A Common Stock for
Class A Common Stock of the Surviving Corporation based on the following
formulas:

                  (i) the number of CVRs shall be adjusted by multiplying the
         number of outstanding CVRs immediately prior to the consummation of the
         Merger by the Class A Exchange Ratio (as such term is defined in the
         Merger Agreement); and

                  (ii) the Reference Price shall be adjusted by dividing the
         Reference Price in effect immediately prior to the consummation of the
         Merger by the Class A Exchange Ratio (as such term is defined in the
         Merger Agreement).



                                                                               6


                  SECTION 1.07. Payment Terms. Payments of any amounts in
respect of the CVRs shall be made, in the Company's sole discretion, subject to
Section 2.02, (i) in cash by wire transfer of immediately available funds to a
bank account designated in writing by the Investor, (ii) by the issuance and
delivery to the Investor of the number of shares of Class A Common Stock
obtained by dividing (x) the payment amount by (y) the product of (I) the 20-Day
Average Price applicable to such payment and (II) 0.95 or (iii) in cash and
shares of Class A Common Stock (with the number of shares of Class A Common
Stock to be issued and delivered being determined by subtracting from the total
payment amount the amount paid in cash and dividing that amount by the product
of (I) the 20-Day Average Price applicable to such payment and (II) 0.95). No
fractional shares of Class A Common Stock shall be issued to any holder of CVRs
in respect of any payment made in the form of shares of Class A Common Stock.
Instead of any fractional shares of Class A Common Stock that would otherwise be
issuable to any such holder, the Company shall pay to such holder in respect of
such fractional interest in an amount in cash equal to the product of (x) such
fractional interest and (y) the 20-Day Average Price applicable to such payment.

                  SECTION 1.08. No Interest on CVR Payments. Other than in the
case of interest on the Default Amount (as defined in Section 3.01) with respect
to any CVR, which shall be calculated in accordance with Section 3.01, no
interest shall accrue on any amounts payable with respect to the CVRs.

                  SECTION 1.09. Determination that No Payment is Due. If the
Company determines that no amount is payable with respect to the CVRs to the
holders thereof on the Maturity Date, the Change of Control Date (if an
Acceleration Election shall have been made by the Investor with respect thereto)
or the Default Payment Date (as defined in Section 3.01), as the case may be,
the Company shall give written notice of such determination to the Investor.
Upon making such determination, absent manifest error, the CVRs and this
Agreement shall terminate and become null and void without any further action on
the part of any party hereto, and the holders thereof and the parties hereto
shall have no further rights with respect thereto or hereto. The failure to give
such notice or any defect therein shall not affect the validity of such
determination.

                                   ARTICLE II

                                    Covenants

                  SECTION 2.01. Payment of Amounts, if any, to Holders of CVRs.
The Company will duly and punctually pay the amounts, if any, in the manner
provided for in Section 1.07, payable with respect to the CVRs in accordance
with the terms of this Agreement.

                  SECTION 2.02. Reservation of Class A Common Shares. The
Company shall be permitted to pay any amounts in respect of CVRs in shares of
Class A Common Stock pursuant to Section 1.07 only if (i) it has reserved for
issuance and delivery upon maturity or early settlement of the CVRs such number
of shares of Class A Common Stock as shall be issuable upon maturity or early
settlement of the CVRs and (ii) the Investor shall have received an opinion from
counsel to the Company, dated the date of such issuance and delivery and


                                                                               6


addressed to the Investor, in form and substance reasonably acceptable to the
Investor, as to the validity of the securities so issued and delivered. All such
shares of Class A Common Stock shall be duly authorized and, when issued, shall
be validly issued, fully paid and nonassessable, free and clear of all liens,
security interests, charges and other encumbrances, and will not have been
issued in violation of any preemptive or similar rights.

                  SECTION 2.03. Antimanipulation. (a) During the period
commencing 180 calendar days prior to the Maturity Date and ending on the date
that is 30 trading days prior to the Maturity Date (the "Limited Sale Period"),
in addition to any restrictions on sales arising under the federal securities
laws or other applicable laws, the Investor shall not, and shall not permit any
of its subsidiaries or controlled affiliates to, sell (including any
constructive sale by means of a hedging, derivative or similar transaction)
shares of Class A Common Stock (i) on any trading day (x) on which the opening
bid with respect to the Class A Common Stock is lower than the closing price on
the preceding trading day by 2% or more or $0.50 or more, whichever is more
restrictive or (y) in an amount greater than the sum of (I) 3.75% of the trading
volume of the Class A Common Stock on the preceding trading day and (II) 3.75%
of the trading volume of the Class A Common Stock during the first half of the
trading day on the date of sale or (ii) during the last hour of trading on any
trading day. In addition, all sales of Class A Common Stock by the Investor and
its subsidiaries and controlled affiliates during the Limited Sale Period (i)
shall comply with the volume limitations required by Rule 144 under the
Securities Act of 1933, as amended (the "Securities Act"), (ii) shall be
effected by means of "brokers' transactions" (as such term is used in Rule 144
under the Securities Act), (iii) shall not constitute the opening transaction in
the security on any trading day and (iv) shall not be at a price that is less
than the prevailing market price (the lowest current independent published bid).

                  (b) During the period commencing 30 trading days prior to the
         Maturity Date and ending on the Maturity Date (the "Restricted
         Period"), (i) the Investor shall not, and shall not permit any of its
         subsidiaries or controlled affiliates to, sell (including any
         constructive sale by means of a hedging, derivative or similar
         transaction), in open market transactions, privately negotiated
         transactions or otherwise, any Class A Common Stock and (ii) the
         Company shall not, and shall not permit any of its subsidiaries or
         controlled affiliates to, repurchase or redeem (or publicly announce an
         intention or plan to repurchase or redeem), or otherwise acquire, in
         open market purchases, privately negotiated transactions or otherwise,
         any Class A Common Stock or Class C common stock, par value $0.01 per
         share, of the Surviving Corporation (the "Class C Common Stock"), or
         any securities convertible into or exchangeable for, Class A Common
         Stock or Class C Common Stock, other than privately negotiated
         repurchases or redemptions of Class C Common Stock.

                  (c) Notwithstanding anything to the contrary in this Section
         2.03, the Investor and its affiliates shall be permitted to sell Class
         A Common Stock (i) during the Restricted Period or (ii) in an amount
         greater than that permitted during the Limited Sale Period, in each
         case if the Investor gives the Company at least 3 business days prior
         notice of its intention to do so. Upon the first to occur of any sales
         that are the subject of such notice or any such sales for which notice
         is not provided in violation of this Section 2.03(c), all of the CVRs
         then outstanding and this Agreement shall thereupon automatically
         terminate and become null and void without any further action on the
         part of any party



                                                                               8



         hereto, and the holders thereof and the parties hereto shall have no
         further rights with respect thereto or hereto.

                  SECTION 2.04. Certain Notices. (a) Subject to Section 2.03(c),
as soon as practicable after the Investor or any of its wholly owned
subsidiaries has sold, transferred or otherwise disposed of any Class A Common
Stock, the Investor shall inform the Company of such sale, transfer or other
disposition by written notice in substantially the form attached as Exhibit A
hereto. Schedule I hereto shall thereupon be adjusted to reduce the number of
outstanding CVRs in accordance with Section 1.04.

                  (b) Whenever an adjustment is made pursuant to Section 1.06,
         the Company shall promptly prepare a certificate setting forth such
         adjustment and a brief statement of the facts accounting for such
         adjustment and shall as promptly as practicably thereafter deliver such
         certificate to the Investor. Any such adjustment absent manifest error
         shall be final and binding on the Company and the Investor. Schedule I
         hereto shall thereupon be adjusted to indicate the number of
         outstanding CVRs after giving effect to such subdivision, combination
         or change, and to indicate the Reference Price then in effect.

                  (c) If an early termination of the CVRs occurs pursuant to,
         and in accordance with, the provisions of Section 1.05, the Company
         shall promptly provide the Investor with written notice of such
         occurrence, together with all information reasonably necessary for the
         Investor to confirm such occurrence.

                  (d) Notwithstanding anything to the contrary in this Section
         2.04, any reduction in the number of outstanding CVRs in accordance
         with Section 1.04, any adjustment to the number of outstanding CVRs or
         the Reference Price in accordance with Section 1.06, or any early
         termination of the CVRs in accordance with Section 1.05 shall, in each
         case, automatically occur upon the happening of the event giving rise
         to such reduction, adjustment or termination, regardless of whether the
         Company has received or given notice of such event or revised Schedule
         I as provided for in this Section 2.04.

                                  ARTICLE III

              Remedies of the Holders of CVRs on Event of Defaults

                  SECTION 3.01. Event of Default Defined; Acceleration of
Maturity. "Event of Default", with respect to CVRs, means any 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 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) the Company shall default in the payment of all or any
         part of the amounts payable in respect of the CVRs as and when the same
         shall become due and payable either at the Maturity Date, or the Change
         of Control Date or otherwise; or





                                                                               9


                  (b) a court of competent jurisdiction shall enter a decree or
         order for relief in respect of the Company in an involuntary case under
         any applicable bankruptcy, insolvency or other similar law now or
         hereafter in effect, or appointing a receiver, liquidator, assignee,
         custodian, trustee or sequestrator (or similar official) of the Company
         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 days; or

                  (c) the Company shall commence a voluntary case under any
         applicable bankruptcy, insolvency or other similar law now or hereafter
         in effect, or consent to the entry of an order for relief in an
         involuntary case under any such law, or consent to the appointment of
         or taking possession by a receiver, liquidator, assignee, custodian,
         trustee or sequestrator (or similar official) of the Company or for any
         substantial part of its property, or make any general assignment for
         the benefit of creditors.

If an Event of Default occurs and is continuing, then, and in each and every
such case, unless all of the CVRs shall have already become due and payable or
have expired or terminated, the Investor by notice in writing to the Company may
declare all CVRs then outstanding to be due and payable immediately (the date of
such notice being the "Default Payment Date"), and upon any such declaration the
Default Amount (as defined below) for each such CVR shall become immediately due
and payable and, thereafter, shall bear interest, calculated at the interest
rate from time to time announced by Citibank, N.A., as its prime rate plus 2%,
until payment is made to the Investor on behalf of the holders of all CVRs then
outstanding, and, upon the payment in full of any such amount, all of the CVRs
then outstanding and this Agreement shall thereupon automatically terminate and
become null and void without any further action on the part of any party hereto,
and the holders thereof and the parties hereto shall have no further rights with
respect thereto or hereto. The term "Default Amount" shall mean (i) with respect
to an Event of Default described in clause (a) of the first sentence of this
Section 3.01, the amount (payable as set forth in Section 1.07) that shall have
become due and payable at the Maturity Date or the Change of Control Date, as
the case may be and (ii) with respect to an Event of Default described in
clauses (b) or (c) of the first sentence of this Section 3.01, the amount
(payable as set forth in Section 1.07), if any, as determined by the Company
(which determination absent manifest error shall be final and binding on the
Company and the Investor), by which (x) the Reference Price exceeds (y) the
20-Day Average Price (with the 20-Day Average Price calculated as if the Default
Payment Date were the Maturity Date), subject to the Payment Cap.

                  SECTION 3.02. Remedies Cumulative; Delay or Omission Not
Waiver of Default. No right or remedy herein conferred upon the Investor is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy. No delay or omission of the
Investor to exercise any right or power accruing upon any Event of Default
occurring and continuing as set forth in Section 3.01 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.



                                                                              10


                                   ARTICLE IV

                      Other Change of Control Transactions

                  SECTION 4.01. Company May Merge, Etc. (a) If at any time prior
to the beginning of the Protection Period the Company proposes to enter into a
Change of Control Transaction in which the capital stock of the Company is
exchanged for or changed into other stock or securities or the Investor does not
make an Acceleration Election pursuant to Section 1.03 in connection with a
Change of Control Transaction during the Protection Period, the Company shall
not consummate such Change of Control Transaction, unless:

                  (i) the surviving person in such Change of Control
         Transaction, or any ultimate parent thereof, if not the Company (the
         "Surviving Person"), is a corporation, partnership or trust organized
         and existing under the laws of the United States of America, any state
         thereof or the District of Columbia and expressly assumes the
         obligation to pay all amounts payable in respect of the CVRs and the
         performance of every covenant of this Agreement on the part of the
         Company to be performed or observed;

                  (ii) immediately after giving effect to such transaction and
         treating any indebtedness which becomes an obligation of the Surviving
         Person, the Company or any subsidiary of the Surviving Person or the
         Company as a result of such transaction as having been incurred by the
         Surviving Person, the Company or such subsidiary at the time of such
         transaction, no Event of Default shall have happened and be continuing;
         and

                  (iii) the Company has delivered to the Investor a certificate
         signed by the chief executive officer or the chief financial officer of
         the Company in his or her capacity as such an officer stating that such
         Change of Control Transaction complies with this Article IV and that
         all conditions precedent herein provided for relating to such
         transaction have been complied with.

                  (b) Nothing in this Section 4.01 shall affect the right of the
Investor to make an Acceleration Election pursuant to Section 1.03 with respect
to any Change of Control Transaction proposed during the Protection Period, and,
if the Investor does not make such an Acceleration Election, the provisions of
Section 1.06 shall apply to such Change of Control Transaction in accordance
with their terms.

                  SECTION 4.02. Successor Substituted. Upon the consummation of
any Change of Control Transaction in accordance with Section 4.01 in which the
Company is not the surviving person in such Change of Control Transaction or the
ultimate parent thereof, the Surviving Person shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under
this Agreement with the same effect as if the Surviving Person had been named as
the Company herein and, thereafter, the predecessor person shall be relieved of
all obligations and covenants under this Agreement and the CVRs.

                  SECTION 4.03. Termination. This Agreement shall terminate and
be of no further force and effect without any further action on the part of any
party hereto automatically upon the termination of all outstanding CVRs in
accordance with the terms hereof.


                                                                              11
