Official Unsecured Creditors Committee 

Ladies
and Gentlemen, 

        The
purpose of this letter agreement (the "Agreement") is to confirm certain agreements among: Comcast Cable Communications, Inc.
("Comcast"), Cox Communications Inc., ("Cox"), Rogers Cable Inc.,
("Rogers"), Insight Communications Company, L.P., Insight Communications Midwest, LLC and Insight Kentucky Partners II, L.P.
("Insight"), Mediacom LLC and Mediacom Broadband LLC and affiliates ("Mediacom"), and Midcontinent
Communications ("Midcontinent Cable") (collectively, the "MSO Customers") the Official Committee of
Unsecured Creditors appointed in At Home Corporation's Chapter 11 bankruptcy case (the "Committee"), and At Home Corporation, a Delaware corporation,
(the "Company"). 

        As
the recipients of this letter are aware, the Company is a debtor in possession in bankruptcy. On September 28, 2001, the Company filed a petition for reorganization under
Chapter 11 of the United States Bankruptcy Code (the "Bankruptcy Code") before the United States Bankruptcy Court, Northern District of California, (the
"Bankruptcy Court") Case No. 01-32495. 

        During
the Term (as defined below) the Company will operate solely for the purpose of continuing to provide the @Home Service (as defined below) and providing Transition Services (as
defined below) to the MSO Customers, after which time the Company intends to cease operations. As a result, the Company and the MSO Customers now desire to provide continuing @Home Service to the MSO
Customers and to facilitate the MSO Customers' transitions on a "market by market" and/or "primary hub by primary hub" basis of their respective high speed Internet service customers from the @Home
Service to a service provided by or on behalf of such MSO Customer, upon the terms and subject to
the conditions set forth in this Agreement. As used in this Agreement, the entities set forth above shall have the meanings provided above, and the following terms shall have the following meanings: 

        "@Home Service" shall mean with respect to an MSO Customer, the high speed Internet service offered by the Company to such MSO Customer as
of November 30, 2001, including, without limitation, provisioning new customers, provided, however, that (i) there will be no provisioning of new customers in new markets or in existing
markets during the ten days preceding the scheduled transition of customers off the Company's network in that market, and (ii) If the Company must incur any new capital costs in order to
satisfy its obligations with respect to provisioning new customers, the Company agrees to promptly notify such MSO Customer of the costs involved. If the Company and such MSO Customer are unable to
mutually agree on the need, amount or payment of such new capital costs, then unless such provisioning is technically impossible without incurring new capital expenditures; Company agrees that,
notwithstanding such failure to agree, it will continue to provision new customers (without making new capital expenditures) as requested by such MSO Customer and such MSO Customer acknowledges that
the quality of the @Home Service may diminish by the addition of such new customer; 

        "AT&T" shall mean AT&T Corp., its affiliates and subsidiaries (other than the Company) and its officers and directors, agents,
representatives and advisors; 

        "Broadband Content and Broadband Portal" shall mean web content located at home.excite.com and home.excite.ca;  provided, however, it shall not include the following services: member services, email, newsgroups, and
webspace; 

        "Distribution Agreements" shall mean, with respect to an MSO Customer, the agreements pursuant to which the Company has provided the @Home
Service to such MSO Customer and rejected by the Company pursuant to that certain order of the Bankruptcy Court, dated November 30, 2001; 

        "Operating Plan" shall have the meaning set out in Article 1.3; 

 

        "Term" shall mean the period from and including December 1, 2001, through and including February 28, 2002; and 

        "Transition Services" shall mean the services provided by the Company as set out in Article 1 of this Agreement. 

	1.
	Transition Services

	1.1
	During
the Term, the Company will provide the @Home Service and Transition Services to the MSO Customers pursuant to the terms set out in this Agreement. The parties acknowledge, that
the Company currently expects that it will not continue to provide the Broadband Content and Broadband Portal during the Term. During the Term, nothing shall prohibit any MSO Customer from offering or
providing any high speed Internet access service to its customers.

	1.2
	The
Transition Services require that, during the Term, the Company: (A) provide the @Home Service on an uninterrupted basis to each market of each MSO Customer as set out in
the Operating Plan; and (B) reasonably cooperate with the MSO Customers to facilitate transitions of each MSO Customer's high speed Internet service customers from the @Home Service to a
service provided by or on behalf of such MSO Customer on a "market by market" and/or "primary hub by primary hub" basis. Subject to Article 1.7 of this Agreement, the parties agree that the
schedule and mode of such transition shall be as agreed in the Operating Plan (as hereinafter defined). Notwithstanding the foregoing, any MSO Customer may transition any of its markets before the
date scheduled for the transition of such market as provided for in the Operating Plan, so long as such early transition does not adversely affect any other MSO Customer;  provided however, that to the
extent that any such MSO Customer executes such an early transition, the Company shall have no obligation to incur any
costs or to provide any Transition Services to such MSO Customer in such market; however, nothing herein shall prohibit the Company from providing transition assistance to such MSO Customer in such
market.

	1.3
	During
the Term, the Transition Services will include but are not necessarily limited to: (i) transfers of subscriber data owned by an MSO Customer (including without
limitation e-mail, webspace, and mailbox account information) reasonably requested by such MSO Customer and transfers of subscriber data not owned by an MSO Customer reasonably requested
by such MSO Customer, provided that all such transfers of subscriber data not owned by such MSO Customer shall comply with all applicable legislation and privacy policies; (ii) 
e-mail forwarding for each MSO Customer's @Home Service customers after any such customer is transitioned from the @Home Service to a service provided by or on behalf of such MSO Customer
until the end of the Term; (iii) URL redirects for each MSO Customer's @Home Service customers after any such customer is transitioned from the @Home Service to a service provided by or on
behalf of such MSO Customer until the end of the Term; (iv) timely transfer of IP addresses necessary to facilitate the transitions; (v) participation in a communications plan with each
MSO Customer's @Home Service customers, which may include, among other things, banner messages and email messages explaining the transition from the @Home Service to a service provided by or on behalf
of such MSO Customer; and (vi) access through the Company's firewall for high speed Internet access customers of any MSO Customer in order to facilitate such customers' use of the Company's
subapplications during the Term, provided that such MSO Customer has provided the Company with a list of such customers and so long as such access is technically feasible and will not cause a breach
of the Company's network, to be determined in the Company's sole discretion after consultation with such MSO Customer. 

2

 

	1.4
	During
the Term, the Company, the MSO Customers and the Committee shall use their respective best efforts to agree to an operating plan to provide the Transition Services on or before
December 7, 2001 (the "Operating Plan"); such Operating Plan may only be amended or modified by all of the parties.

	1.5
	During
the Term, subject to Articles 1.1 and 1.2, the Transition Services shall be provided as mutually agreed upon by the MSO Customers and the Company;  provided that the Company and each of the MSO Customers
shall provide authorized representatives of the Company and each of the MSO Customers, as
appropriate, with reasonable access to the other's facilities, equipment and personnel to the extent necessary to perform the services contemplated in this Agreement.

	1.6
	Commencing
on the date hereof and during the Term, the Company shall begin using all reasonable efforts to cooperate with the MSO Customers to facilitate a transition of their
respective high speed Internet service customers from the @Home Service to a service provided by or on behalf of such MSO Customer, in accordance with the Operating Plan, on a "market by market"
and/or "primary hub by primary hub" basis.

	1.7
	During
the Term, the parties acknowledge that the provision of the Transition Services by the Company may require the license of certain intellectual property rights owned or licensed
by the Company to each of the MSO Customers at no cost to the Company or to the MSO Customer, and that the payments by the MSO Customers hereunder include a payment in respect of such license. The
parties agree to use commercially reasonable efforts to promptly take all required actions to make effective any required licenses or sublicenses.

	1.8
	During
the Term, the parties agree to use their commercially reasonable efforts to cooperate with one another to facilitate the provision of the Transition Services in a manner that
assists the Company in reducing its costs and creates economic efficiencies for the Company by considering the Company's concurrent transition of several MSO Customers to services provided by or on
behalf of such MSO Customer. In furtherance and not in limitation of the foregoing, the Company agrees, when appropriate and commercially reasonable for the Company, to enter into Internet traffic
peering agreements with each of the MSO Customers for the purpose of reducing each party's costs. 

	2.
	Payment

	2.1
	Promptly
upon issuance of the order of the Bankruptcy Court substantially similar to that set forth in Exhibit 2.1, each MSO Customer will pay to the Company for the @Home
Service and Transition Services the amount set forth in Exhibit 2.1 (in an aggregate amount not less than US$355,000,000) with respect to such MSO Customer (the
"Transition Fee"). The Company will be allowed to access and to use these Transition Fees for Company purposes only as follows:

	(a)
	Provided
that the Company has not materially breached its obligations hereunder, prior to approval of this Agreement by the Bankruptcy Court the Company will be allowed to access and
use US$2,000,000 per day.

	(b)
	Provided
that the Company has not materially breached its obligations hereunder, from and after the day on which the Bankruptcy Court approves this Agreement, the Company will be
allowed to access and use for Company purposes, for the remainder of the Term, US$3,944,445 per day up to the total amount of the Transition Fees. On February 28, 2002, in addition to the other
withdrawals hereunder, and provided that the Company has not materially breached its obligations hereunder, the Company will be allowed to withdraw the
remaining funds in the Transition Fees account, including any accrued interest. 

3

 

	2.2
	All
payments shall be made by wire transfer of same day funds. 

	3.

EXHIBIT 10.1(19)    
  

EXECUTION  

 
  FOURTH AMENDMENT AGREEMENT    
  

        This Fourth Amendment Agreement dated as of December 11, 2001 ("Amendment") is entered into with reference to (a) the Second Amended and Restated
Loan Agreement dated as of April 10, 2000 (the "Second Amended and Restated Loan Agreement") and (b) the 364-Day Loan Agreement dated as of April 6, 2001 (the
"364-Day Loan Agreement" and, together with the Second Amended and Restated Loan Agreement, the "Loan Agreements"), in each case among MGM MIRAGE, a Delaware corporation (formerly known as
MGM Grand, Inc. and referred to herein as "Borrower"), MGM Grand Atlantic City, Inc., a New Jersey corporation ("Atlantic City"), MGM Grand Detroit, LLC, a Delaware limited liability
company ("Detroit"), as Co-Borrowers, the Banks named therein, and Bank of America, N.A., as Administrative Agent. The Second Amended and Restated Loan Agreement has previously been
amended by Amendment Agreements dated as of September 6, 2000, December 21, 2000 and April 6, 2001; the 364-Day Loan Agreement has not previously been amended.
Borrower, Atlantic City, Detroit and the Administrative Agent, acting on behalf of the Requisite Banks under each of the Loan Agreements, hereby agree to amend each of the Loan Agreements as follows: 

        1.    Definitions.    Capitalized terms used herein but not defined are used with the
meanings set forth for those terms in the Loan Agreements. 

        2.    Restricted Subsidiaries\Midwest Gaming Subsidiaries.    Section 1.1 of each
of the Loan Agreements is hereby amended by adding thereto a new definition of "Midwest Gaming Subsidiaries" and by
amending the definition of "Restricted Subsidiary" to read in full as follows (with the added text shown as double underscored bold for the convenience of the reader): 

        "Midwest Gaming Subsidiaries" means one or more Subsidiaries of Borrower collectively formed or acquired for
the purpose of design, development, construction, ownership and operation of a single gaming resort or gaming complex (in each case which may include related hotel, entertainment, and restaurant
operations) in the Midwest United States, and pure holding companies for such Subsidiaries, in each case which, following their designation by Borrower as Unrestricted Subsidiaries, engage in no other
substantial operations and own no other substantial asset. 

        "Restricted Subsidiary" means each Subsidiary of Borrower  other than (a) the Australia Companies, Detroit Temporary, Monorail, Subsidiaries formed
under the Laws of foreign
nations whose only tangible assets are located in foreign nations, and pure holding companies for such foreign Subsidiaries (including without limitation MGM Grand South Africa, Inc., a Nevada
corporation) owning as their sole asset the stock or other securities and obligations thereof, and (b) each Midwest Gaming Subsidiary which is designated in
writing by Borrower to the Administrative Agent as an Unrestricted Subsidiary substantially contemporaneously with its formation or acquisition, provided that no such designation may be made when any
Default or Event of Default exists. As of the Closing Date, Victoria Partners, a Nevada general partnership, is 50% owned by Borrower, and is therefore not a
Subsidiary of Borrower. It is also understood that Marina District Development Holding Co., LLC, a New Jersey limited liability company, the 100% owner of Marina
District Development Company, LLC, a New Jersey limited liability company doing business as "The Borgata," is also only 50% owned by Borrower and therefore is not a Subsidiary of
Borrower."

        3.    Leverage Kicker.    Section 1.1 of each of the Loan Agreements is further
amended by amending the definitions of "Base Rate Margin" and "Eurodollar Margin" to add the following text thereto: 

"
provided that, during each Pricing Period which begins following December 31, 2001 and which begins immediately
following the last day of a Fiscal Quarter upon which the Leverage Ratio exceeds 6.25:1.00, the interest rate margins set forth above shall be increased by 10.0 basis points above the interest rate
margins otherwise applicable during such Pricing Period." 

        4.    Technical Amendment to Funded Debt Definition.    Section 1.1 of each of the
Loan Agreements is further amended so that the definition of "Funded Debt" reads in full as follows (with the deleted text shown as stricken and the added text shown as double underscored bold for the
convenience of the reader): 

"  Funded Debt" means, as of any date of determination, the  sum (without duplication) of (a) all principal Indebtedness
of Borrower and its Restricted Subsidiaries for borrowed
money ( including debt
securities issued by Borrower or any of its Restricted Subsidiaries) on that date ( other than any such Indebtedness to the
extent it has been legally or contractually defeased or is the subject of a deposit in Cash or Cash Equivalents for the purpose of defeasing the same in accordance with its terms),  plus
(b) the aggregate amount of all Capital Lease Obligations of Borrower and its Restricted Subsidiaries on that
date, plus (c) obligations in respect of letters of credit or other similar instruments which support Indebtedness
of the type described in clause (a) (except as limited by the definition of Indebtedness), to the extent of the amount drawable under such letters of credit or similar instruments,  provided
that no Guaranty Obligation by Borrower or its Restricted Subsidiaries of the Indebtedness of another Person shall
be deemed to be Funded Debt except to the extent that Generally Accepted Accounting Principles require that Guaranty Obligation to be set forth on a
combined balance sheet of Borrower and its Restricted Subsidiaries (and not merely
as a footnote) as the exposure of Borrower and its Restricted Subsidiaries with respect thereto. 

        5.    Amendment to Section 6.8—Leverage Ratio.    Section 6.8
of each of the Loan Agreements is hereby amended to read in full as follows: 

        "6.8 Leverage Ratio.    Permit the Leverage Ratio, as of any Fiscal Quarter described below to be
greater than the ratio set forth below opposite that Fiscal Quarter: 

	Fiscal Quarters Ending

        6.    Amendment to Section 6.9—Interest Charge Coverage
Ratio.    Section 6.9 of each of the Loan Agreements is hereby amended to read in full as follows: 

        "
6.9 Interest Charge Coverage Ratio.    Permit the Interest Charge Coverage Ratio as of the last
day of any Fiscal Quarter described below, to be less than the ratio set forth opposite that Fiscal Quarter: 

	Fiscal Quarters Ending

3.00:1.00	
."

        7.    New Section 6.10—Certain Covenants Contingent Upon the Leverage
Ratio.    Each of the Loan Agreements is hereby amended to add a new Section 6.10 thereto, to read in full as follows: 

        "
6.10 Certain Covenants Contingent Upon Leverage Ratio.    During each Restricted Period, Borrower
shall not, and shall not permit its Restricted Subsidiaries to: 

        (a)  Make
or declare any Distribution consisting of a dividend in Cash or Cash Equivalents to Borrower's shareholders; 

        (b)  Make
or commit to make any Restricted Expenditure which: 

          (i)  to
the extent that the Trigger Date occurs prior to December 31, 2002, and when aggregated with all other Restricted Expenditures made or committed to be made
during the period between the Trigger Date and December 31, 2002, would exceed the sum of (x) $550,000,000  plus (y) the net
cash proceeds to Borrower (after transactional expenses) from the issuance of equity securities
during the period between December 1, 2001 and the date of the Restricted Expenditure; or 

        (ii)  in
any event, when aggregated with all other Restricted Expenditures made or committed to be made during such period, would exceed, during the four consecutive Fiscal
Quarter period commencing immediately following the Trigger Date, the sum of: 

        (x)  $650,000,000;
plus

        (y)  the
net cash proceeds to Borrower (after transactional expenses) from the issuance of equity securities during the period between December 1, 2001 and the last
day of such period, provided that to the extent that the addition of any such net cash proceeds is required to assure
compliance by Borrower with this covenant, such net cash proceeds may be added only during the first Fiscal Quarter when required and the three immediately succeeding Fiscal Quarters; 

        (c)  Repurchase,
redeem, retire, prepay or acquire, in each case prior to the date when due, any Subordinated Obligations,  provided that Borrower may refinance any Subordinated Obligations to the extent
consummated using the proceeds of other
concurrently issued Subordinated Obligations; or 

        (d)  Enter
into any Guaranty Obligation with respect to Indebtedness which results in the aggregate principal amount of the potential liability of Borrower and its Restricted

        "Common Stock" means Borrower's common stock having ordinary voting power. 

        "Excess Acquisition Cost" means, in respect of each Acquisition made or committed to be made by Borrower or
its Restricted Subsidiaries during a Restricted Period, that portion of the consideration for such Acquisition which is not Common Stock (including consideration consisting of any assumption of
Indebtedness) which results in the Acquisition Cost Ratio for that Acquisition being in excess of the ratio set forth below opposite the Fiscal Quarter during which such Acquisition is consummated: 

	Fiscal Quarters Ending
 
	 	Maximum Ratio
	 
	December 31, 2001	 	5.25:1.00

Expenditures (including any Maintenance Capital Expenditure, but excluding that portion of any Capital Expenditure which is properly treated as capitalized
interest under Generally Accepted Accounting Principles); 

        (b)  Distributions
other than those consisting of a dividend in Cash or Cash Equivalents to Borrower's shareholders; 

        (c)  Investments
in any Person which is not a wholly-owned Subsidiary of Borrower; and 

        (d)  Acquisitions,
to the extent of any Excess Acquisition Cost. 

        "Restricted Period" means the period beginning on (a) the day immediately following any Trigger Date
and ending on (b) the last day of the first subsequent Fiscal Quarter upon which the Leverage Ratio is equal to or less than 5.50:1.00. 

        "Target EBITDA" means, in respect of each Person or assets which are the subject of any Acquisition, the  lesser of: 

        (a)  the
EBITDA of the Person acquired (or associated with the assets so acquired) for the most recent twelve month period for which relevant financial statements are
available on the date of the consummation of such Acquisition; and 

        (b)  the
projected EBITDA of such Person (or associated with the assets so acquired) for the twelve month period following the consummation of such Acquisition, after giving

purchasing efficiencies and other operational savings;

each case as certified to the Administrative Agent by Borrower in a writing delivered to the Administrative Agent. 

        "Trigger Date" means the last day of each and any Fiscal Quarter occurring on or after December 31,
2001, upon which the Leverage Ratio exceeds 5.50:1.00. 

        8.    Conditions Precedent.    The effectiveness of this Amendment shall be conditioned

time) on November 28, 2001, and (iii) an arrangement fee for the sole account of the Lead Arranger in an amount set forth in a letter agreement between Borrower and the Lead Arranger. 

        9.    Representation and Warranty.    Borrower and each of the Co-Borrowers
represents and warrants to the Administrative Agent and the Banks that no Default or Event of Default has occurred and remains continuing, and that each of the representations and warranties of
