Termination of Existing Commitments:  AOL’s purchase commitment respecting Commitment Ports and Uncommitted Ports set forth in the letter agreement dated October 13, 2005 between Level 3 and America Online, Inc. (“2005 Purchase Commitments”) shall be terminated as of September 30, 2006 and shall thereafter have no further force or effect.

Revised Purchase Commitment:  In place of the 2005 Purchase Commitments, AOL commits that it will maintain the Committed Percentage (as defined below) of AOL’s Total AOL Dial-up Hours (as defined below) with Level 3 under the Managed Modem Agreement (the “Purchase Commitment”) during each of (i) October 1, 2006 – December 31, 2006; (ii) January 1, 2007 – June 30, 2007; (iii) July 1, 2007 – December 31, 2007; and (iv) January 1, 2008 – June 30, 2008) (each a “Commitment Period” and collectively the “2006 through 2008 Commitment Periods”). The Committed Percentage shall be: (i) as of October 1, 2006, January 1, 2007, July 1, 2007 and January 1, 2008, the percentage of AOL’s Total AOL Dial-up Hours then supported on the Level 3 network (provided that if such percentage is greater than [****] percent [****], the Commitment Percentage shall be capped at [****]), of which percentage AOL will notify Level 3, with supporting documentation, on or before, as applicable, October 15, 2006, January 15, 2007, July 15, 2007 and January 15, 2008, provided that (ii) when the total percentage of AOL’s Total AOL Dial-up Hours then supported on the Level 3 network reaches [****], the Committed Percentage shall be [****] as of the start of the next Commitment Period and for each Commitment

Period thereafter. “Total AOL Dial-up Hours” shall mean the aggregate number of dial-up service hours delivered by AOL in the United States to all of AOL’s dial-up access vendors, including Level 3, during the applicable Commitment Period, minus Excluded Hours (as defined in Section 4 below). AOL agrees that it will not to resell Managed Modern Service to non-affiliated third parties on a wholesale or stand alone basis without the advance written consent of Level 3 and that if it sells or otherwise provides Managed Modem Service to affiliated third parties, that it shall restrict such affiliated third parties from reselling the Managed Modem Service on a wholesale or stand alone basis.

Excluded Hours:  Total AOL Dial-up Hours in excess of: i) [****] each month for the remainder of 2006; ii) [****] each month in 2007; and iii) [****] each month in 2008 shall be excluded from Total AOL Dial-up Hours (“Excluded Hours”).

Distribution of Traffic:  With respect to Managed Modem Service traffic that applies to the Purchase Commitment, [****] However, the parties acknowledge that the ratio of Tier 1 to the combined Tier 2 and Tier 3 traffic on the Level 3 network may change over time as a natural result of non uniform rates of broadband adoption across Tier 1, Tier 2 and Tier 3 and the attrition of AOL service subscribers. The list of rate centers (“Rate Centers”) and associated Tiers is listed in Exhibit A attached hereto.

Incentive Discount:  Provided that AOL delivers over [****] percent [****] of the Total AOL Dial-up Hours to Level 3 during the fourth calendar quarter of 2006 (i.e., from October 1, 2006-December 31, 2006), Level 3 will issue AOL a [****] credit on its February 2007 invoice for Managed Modem Service. If on October 1, 2006 the percentage of AOL’s Total AOL Dial-up Hours then supported on the Level 3 network is less than [****] percent [****], then Level 3 agrees to issue the credit on its February 2007 invoice as stated above notwithstanding AOL’s failure to achieve the [****] threshold.

Commitment Validation:  By the 15^th day of the next month following the end of each applicable Commitment Period as set forth in Section 3 of this Letter Agreement, AOL shall present Level 3 with a written certification and supporting documentation which demonstrates to Level 3’s reasonable satisfaction that Total AOL Dial-up Hours in the Commitment Period exceeded the Purchase Commitment. Level 3 reserves the right to audit AOL’s relevant books and records to verify AOL’s satisfaction of the Purchase Commitment in any Commitment Period and AOL’s achievement of the incentive discount described in Section 6 of this Letter Agreement. If at the end of a Commitment Period, AOL has failed to satisfy the Purchase Commitment, ▇▇▇▇▇ ▇ ▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇ ▇▇▇ ▇▇▇▇▇ ▇▇▇ ▇▇▇▇▇ ▇ a shortfall fee equal to [****].

Upon expiration of the Term, AOL will have the option to renew the Managed Modem Agreement, as amended, including but not limited to by this Letter Agreement, for one (1) additional year under the then-current terms and conditions, including Purchase Commitment level and pricing. For avoidance of doubt, in the event AOL elects to extend the Managed Modem Agreement for an additional one year period, such one year period will be divided into biannual Commitment Periods. Upon expiration of termination of the Managed Modem Agreement, AOL shall be entitled to the post-expiration transition assistance described in Section

13 of Amendment No. 1 to the Managed Modem Agreement for a period of time not to exceed [****] (“Transition Assistance”).

The implementation plan will include the obligation of AOL to: (i) obtain and provide to ▇▇▇▇▇ ▇ promptly following the date of this Letter Agreement (if not already provided) all necessary letters of authority (LOAs) required to port-in to ▇▇▇▇▇ ▇ all [****] telephone numbers (identified in Exhibit “D” hereto) associated with AOLs existing dial-up network services provider, including LOAs between (a) AOL’s current dial-up network services vendor for which telephone numbers will be ported to Level 3 and (b) such vendor’s underlying suppliers, authorizing the transfer of such telephone numbers to Level 3; provided, however, that: (a) AOL reserves the right to withdraw telephone numbers from the list of LOAs and remove such telephone numbers from the implementation plan on 60 days prior written notice from AOL to Level 3 and b) AOL may only withdraw telephone numbers under subpart (a) immediately above where the remaining telephone numbers (after such withdrawals) will accommodate the below milestone percentages; (ii) not delay the porting-in of telephone numbers or the migration of traffic to Level 3; and (iii) reasonably cooperate with Level 3 upon request in such porting and migration efforts as respects AOL’s current dial up access provider.

For example, if AOL’s demand in Market A increases by 1,000 ports while demand decreases by 500 ports in Market B and another 500 ports in Market C, AOL may reallocate the

ports from Markets B and C to Market A without any relocation or installation fees related to such [****] ports.
