following:

                  (a) the release or waiver, by operation of law or otherwise,
of the performance or observance by the Issuer of any express or implied
agreement, covenant, term or condition relating to the Common Securities to be
performed or observed by the Issuer;

                  (b) the extension of time for the payment by the Issuer of all

the terms of the Common Securities or the extension of time for the performance
of any other obligation under, arising out of, or in connection with, the Common
Securities (other than an extension of time for payment of Distributions, that
results from the extension of any interest payment period on the Debentures
permitted by the Indenture);


                                       3

sale of any collateral, receivership, insolvency, bankruptcy, assignment for the

                  (e) any invalidity of, or defect or deficiency in the Common
Securities;

                  (f) the settlement or compromise of any obligation guaranteed
hereby or hereby incurred; or

                  (g) any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a guarantor, it being
the intent of this Section 2.04 that the obligations of the Guarantor hereunder
shall be absolute and unconditional under any and all circumstances.

                  There shall be no obligation of the Holders or any other
Person to give notice to, or obtain consent of, the Guarantor with respect to
the happening of any of the foregoing.

                  SECTION 2.05 The Guarantor expressly acknowledges that any
Holder may institute a legal proceeding directly against the Guarantor to
enforce its rights under this Common Securities Guarantee, without first
instituting a legal proceeding against the Issuer or any other Person.

                  SECTION 2.06 This Common Securities Guarantee creates a
guarantee of payment and not of collection. This Common Securities Guarantee
will not be discharged except by payment of the Guarantee Payments in full
(without duplication of amounts theretofore paid by the Issuer) or upon
distribution of Debentures to Holders as provided in the Declaration.

                  SECTION 2.07 The Guarantor shall be subrogated to all (if any)
rights of the Holders against the Issuer in respect of any amounts paid to such
Holders by the Guarantor under this Common Securities Guarantee and shall have
the right to waive payment by the Issuer pursuant to Section 2.01; provided,
however, that the Guarantor shall not (except to the extent required by
mandatory provisions of law) be entitled to enforce or exercise any rights which
it may acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Common Securities
Guarantee, if, at the time of any such payment, any amounts are due and unpaid
under this Common Securities Guarantee. If any amount shall be paid to


                                       4
   6
the Guarantor in violation of the preceding sentence, the Guarantor agrees to
hold such amount in trust for the Holders and to pay over such amount to the
Holders.

                  SECTION 2.08 The Guarantor acknowledges that its obligations
hereunder are independent of the obligations of the Issuer with respect to the
Common Securities and that the Guarantor shall be liable as principal and as
debtor hereunder to make Guarantee Payments pursuant to the terms of this Common
Securities Guarantee, notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 2.04 hereof.

                  SECTION 2.09 The Guarantor acknowledges its obligation to
issue and deliver Class A common stock upon the conversion of the Common
Securities.

                  SECTION 2.10 The Holders of a majority in liquidation amount
of Common Securities may by vote, on behalf of the Holders of all of the Common
Securities, waive any past Guarantee Event of Default and its consequences. Upon
such waiver, any such Guarantee Event of Default shall cease to exist, and any
Guarantee Event of Default arising therefrom shall be deemed to have been cured,
for every purpose of this Common Securities Guarantee, but no such waiver shall
extend to any subsequent or other default or Guarantee Event of Default or
impair any right consequent thereon.

                                   ARTICLE III

                  SECTION 3.01 So long as any Common Securities remain
outstanding, if (i) there shall have occurred and be continuing a Debenture
Event of Default, a Declaration Event of Default or an event that, with the
giving of notice or the lapse of time or both, would constitute a Debenture
Event of Default or a Declaration Event of Default or (ii) a selection by the
Guarantor of a Deferral Period as provided in the Indenture and such period, or
any extension thereof, shall be continuing, then (a) the Guarantor shall not
declare or pay any dividend on, or make any distributions with respect to, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
its capital stock (other than stock dividends paid by the Guarantor which
consist of the stock of the same class as that on which the dividend is being
paid), (b) the Guarantor shall not make any payment of interest, principal or
premium, if any, on or repay, repurchase or redeem any debt securities issued by
the Guarantor which rank pari passu with or junior in interest to the Debentures
and (c) shall not make any guarantee payments with respect to any guarantee by
the Guarantor of the debt securities of any subsidiary of the Guarantor if such
guarantee ranks pari passu with or junior in interest to the Debentures (in each
case, other than (A) dividends or distributions in the Guarantor's common stock,
(B) any declaration of a dividend in connection with the implementation of a
stockholders' rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto, (C)
payments under the Guarantee, (D) purchases or acquisitions of shares of the
Guarantor's common stock in connection with the satisfaction by the Guarantor of
its obligations under any employee benefit plan or any other contractual
obligation of the Guarantor (other than a contractual obligation ranking
expressly by its terms pari passu with or junior in interest


                                       5
   7
to the Debentures), (E) as a result of a reclassification of the Guarantor's
capital stock or the exchange or conversion of one class or series of the
Guarantor's capital stock for another class or series of the Guarantor's capital
stock or (F) the purchase of fractional interests in shares of the Guarantor's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged).

                  SECTION 3.02 This Common Securities Guarantee will constitute
an unsecured obligation of the Guarantor and will rank subordinate to all
Secured Senior Debt of the Guarantor to the same extent that the Debentures (as
defined in the Indenture) are subordinated pursuant to the Indenture.

                                   ARTICLE IV

                  SECTION 4.01 This Common Securities Guarantee shall terminate
upon (i) full payment of the amount payable upon redemption of the Common
Securities, (ii) the distribution of the Guarantor's Class A common stock to the
Holders in respect of the conversion of the Common Securities into the
Guarantor's Class A common stock, (iii) the distribution of the Debentures to
the Holders in exchange for all of the Common Securities or (iv) full payment of
the amounts payable in accordance with the Declaration upon liquidation of the
Issuer. Notwithstanding the foregoing, this Common Securities Guarantee will
continue to be effective or will be reinstated, as the case may be, if at any
time any Holder of Common Securities must restore payment of any sums paid under
the Common Securities or under this Common Securities Guarantee.

                  SECTION 5.01 All guarantees and agreements contained in this

                  SECTION 5.02 Except with respect to any changes which do not

be required), this Common Securities Guarantee may only be amended with the
prior approval of the Holders of a majority in liquidation amount of the
outstanding Common Securities. The provisions of Section 12.02 of the
Declaration with respect to meetings of Holders of the Securities apply to the
giving of such approval.
