 EXECUTION COPY 
  

	 	b.	Revised Port Commitments 

 From the
Effective Date of this Letter Agreement, the parties agree to the following commitment levels in lieu of the above2: 
  

	 	i.	 AOL shall purchase from and maintain with Level 3, [****] ports per month through December 31, 2006, subject to the decommissioning rights set forth in
Section 6 below (the “Commitment Ports”). 

  

	 	ii.	 All ports in excess of the Commitment Ports being purchased as of the Effective Date (i.e., over [****] ports) shall not be subject to a term commitment
by AOL and shall be maintained on an uncommitted basis, subject to the decommissioning rights set from the Section 6 below (the “Uncommitted Ports”). The number of Uncommitted Ports is [****]. 

  

	3.	 Term.  The Commitment Ports and the Uncommitted Ports shall be provided to AOL by Level 3 through December 31, 2006
(“Term”), subject to (a) the decommissioning rights set forth in Section 6 below; and (b) the Transition Assistance described in Section 13 of Amendment 1 to the Managed Modem Agreement dated March 29, 2002
following expiration or termination. 

  

	4.	 Pricing.  The Port Charge for all ports shall remain [****] per port per month through December 31, 2005 with the exception of the
[****] ports purchased under Amendment No. 2 to the Managed Modem Agreement, for which the Port Charge shall remain [****] through December 31, 2005. Beginning January 1, 2006, the Port Charge shall adjust as follows:

  

						
	Ports	  	Monthly Price per Port from
1/1/2006	 	 	Number of Ports
	 Commitment
Ports
	  	[	****] 	 	 Applies to ports 1 through
[****]

	 Commitment Ports
	  	[	****] 	 	 Applies to port [****] through
[****]

	 Uncommitted

terms set forth in Section 2.2(b) of the Managed Modem Agreement. 

  

	6.	Decommissioning Process. 

 The decommissioning process stated below is in lieu of AOL’s decommissioning rights as stated in the Managed Modem Agreement. 
  

	 	a.	 Uncommitted Ports: Prior to January 1, 2006, AOL may decommission Uncommitted Ports by porting the telephone number associated with such ports to
AOL’s designees. AOL will provide Level 3 advance notice of the telephone numbers that will be ported from Level 3 to AOL’s designees with the port quantities associated with each telephone number that will be decommissioned following the
porting of such numbers. Upon completion of a telephone number being ported to AOL’s designee, the associated port quantities shall be decommissioned immediately and billing for such ports shall cease. From January 1, 2006, AOL may
decommission any Uncommitted Ports upon thirty (30) days prior written notice.

	By agreement of the parties, AOL decommissioned [****] of the ports identified in Section 2(a) above prior to the parties’ execution of this Letter Agreement.

 EXECUTION COPY 
  

	 	b.	Commitment Ports: 

 i.    [****] Commitment Ports.    From January 1, 2006, AOL may decommission the ports priced at [****] (referenced in Section 4 above (the “[****] Commitment Ports”))
pursuant to the terms of the Managed Modem Agreement. 
 ii.    [****] Commitment
Ports.    From January 1, 2006, AOL may decommission the ports priced at [****] Commitment Ports (referenced in Section 4 above (the “[****] Commitment Ports”)) based on the same percentage as the monthly
decline in the total amount of AOL’s dial-up traffic across all third party networks between calendar months, if any. The monthly percentage decline in AOL traffic will be determined based on the average daily hours of dial-up traffic across
all AOL third party dial-up access networks (“Average Daily Hours”), based on the following formula: 
 [****] 

AOL will have the right to decommission any physical ports on the Level 3 network as of the 15th day of the calendar month following the measurement periods outlined above. 
 On or about the first day of each calendar month, AOL will provide a non-binding estimate of the anticipated Average
Daily Hours, Monthly Percentage Decline, and Monthly Decommissioning Amount for the most recent month. By the 15th day of the month, AOL will provide formal notice of the actual number of ports to be decommissioned for the month as determined based upon the actual Average Daily Hours, Monthly Percentage Decline and Monthly
Decommissioning Amount calculations for the most recent month (and will provide Level 3 with the Average Daily Hours and the Monthly Percentage Decline used in such determination). Any such ports shall be considered cancelled (and billing shall
cease) as of the 15th day of that month. 
 For example, if Average Daily Hours across all third party networks is [****] in March of 2006 and Average Daily Hours across all third
party networks is [****] in April of 2006, the Monthly Percentage Decline in hours is [****] during the month of April 2006. AOL would therefore have a right to decommission [****] of the then current number of [****] Commitment Ports (such that if
there were [****] Commitment Ports, AOL could decommission [****] of them). On or about May 

			
		  	EXECUTION COPY

  
 
1, 2006, AOL would provide a non-binding estimate of the anticipated Average Daily Hours and Monthly Percentage Decline for the Month of April and the
expected port decommissioning amount (if any). AOL would then provide a formal notice by May 15, 2006 with the quantity and location of ports to be decommissioned with effect from May 15, 2006 (and will provide Level 3 with the Average
Daily Hours and the Monthly Percentage Decline used in determining the quantity of ports to be decommissioned). From May 15, 2006, AOL would retain [****] ports at [****]/port/month. 
 iii) Ports decommissioned under sub-part 6(b)(ii) above may not then be used to effectuate a decommissioning under sub-part 6(b)(i) above.
Level 3 shall have the audit rights stated in Section 2.2(e) of the Managed Modem Agreement to verify the foregoing calculations. 
  

	7.	 Managed Modem Services Agreement.    All ports provided by Level 3 to AOL after the Effective Date of this Letter
Agreement will (a) be identified according to a market designation (where multiple rate centers are pooled into each market designation); (b) be managed as a single Level 3 network (i.e., where Level 3 has migrated the Dial-Up Access
Services previously managed at the rate center level and provided under the Network Services Agreement to the Level 3 network); and (c) shall be governed by the terms of this Letter Agreement and the terms of the Managed Modem Agreement.

  

	8.	 Invoicing.    AOL will pay the monthly invoice for the Managed Modem Services in full by the end of the month provided that AOL
receives an accurate invoice for the Managed Modem Services by the first day of such month. Level 3 will continue to invoice AOL in arrears for [****] ports that contribute to the Commitment Ports and in advance for all other Managed
Modem Services (i.e., the remaining [****] Commitment Ports and the Uncommitted Ports). 

  

	9.	 ICG Ports.    The [****] ports purchased by AOL under the ICG Network Services Agreement, as amended (and subsequently assigned
to Level 3) are not affected by this Letter Agreement. 

  

	10.	 Order of Precedence.    Except as provided herein, the terms of this Letter Agreement shall govern all ports purchased by AOL
from Level 3 as of the Effective Date. In the event the terms of this Letter Agreement conflict with the terms of the Managed Modem Agreement, the terms of this Letter Agreement shall govern. 

 If you are in agreement with the foregoing, please execute one copy of this letter and return it to the undersigned at your earliest convenience.

	 	Re:	 Amended and Restated Agreement for Delivery of Service between Level 3 Communications, LLC (“Level 3”) and America Online, Inc. effective as of
April 18, 2000, as amended (the “Managed Modem Agreement”); and 

 Network Services
Agreement between AOL and BBN Corporation (predecessor to Genuity Solutions Inc. (“Genuity”)) effective as of December 31, 1999, as amended (the “Genuity Network Services Agreement”); and  
 Network Services Agreement between AOL and ICG Telecom Group, Inc. effective as of March 6, 2002 and which has been assigned to
Level 3, as amended (the “ICG Network Services Agreement”) (collectively with the Managed Modem Agreement and Genuity Network Services Agreement, the “Narrowband Agreements”). 
 Dear Kevin: 
 This letter memorializes our agreement
concerning certain commitments under the Narrowband Agreements (the “Letter Agreement”). Capitalized terms used but not defined herein shall have the meanings set forth in the Managed Modem Agreement. 
  

	 	1.	 Name Change:  The parties acknowledge that the legal entity formerly known as America Online, Inc., a Delaware corporation, has changed its name
to AOL LLC (“AOL”), a Delaware limited liability company, and that all references in the Narrowband Agreement to “America Online, Inc.”: or “AOL” refer to AOL LLC. 

  

	 	2.	 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.

  

	 	3.	 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 

  

 1 

	 	 
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. 

  

	 	4.	 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”). 

  

	 	5.	 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. 

  

	 	6.	 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.

  

	 	7.	 Commitment Validation:  By the 15th 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, Level 3 shall assess and AOL shall pay Level 3 a shortfall fee equal to [****]. 

  

	 	8.	 Term; Renewal; Transition Assistance:  The Term of the Managed Modem Agreement will extend through June 30, 2008. 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

  

 2 

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

  

	 	9.	 Pricing:  The Port Charge shall be revised such that (i) from and after the date of this Letter Agreement, AOL’s first [****] ports
shall have a Monthly Price per port of [****], the next [****] ports shall have a Monthly Price per port of [****], and additional ports (excluding the ports being delivered under the ICG Network Services Agreement (the “ICG Ports”) shall
have a Monthly Price per Port of [****] from and after the date those incremental ports are installed and the telephone numbers associated with those ports are ported-in to the Level 3 network; and (ii) from July 1, 2006, all ports
(excluding the ICG Ports) shall have a monthly Port Charge of [****]. 

  

	 	10.	 Termination of Network Services Agreements:  As of the date of this Letter Agreement respecting the Genuity Network Services Agreement and as of
July 1, 2006 respecting the ICG Network Services Agreement, such agreements shall be terminated and any services provided there under which were not previously governed by the Managed Modem Agreement shall be governed by the Managed Modem
Agreement as amended. 

  

	 	11.	 Implementation Milestones:  The parties will mutually agree on an implementation plan to migrate traffic from an existing AOL dial-up network
services vendor to the Level 3 network. The implementation plan will include the obligation of AOL to: (i) obtain and provide to Level 3 promptly following the date of this Letter Agreement (if not already provided) all necessary letters of
authority (LOAs) required to port-in to Level 3 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. The parties acknowledge and agree that Subsection (i)(a) above has been completed by AOL and no further obligations
exists. As part of the joint implementation plan, the parties have agreed upon certain milestones dates that Level 3 shall endeavor to meet related to the migration of traffic and Level 3’s ability to successfully port-in telephone numbers and
associated traffic from AOL’s third-party dial-up network services provider, as stated in the chart below. The percentages stated in the chart below shall be the percentage of AOL’s Total AOL Dial-up Hours corresponding to each Rate Center
(and telephone number) as such Rates Centers and telephone numbers are identified in Exhibit “D.” To determine the total percentage of overall Total AOL Dial-up Hours successfully ported-in to the Level 3 network (and whether the below
milestones have been achieved) for each telephone number identified in Exhibit “D” successfully ported-in to Level 3, the corresponding “% of AOL Traffic” stated in Exhibit “D” shall be added together (the
“Percentage”).

 3 

	 	*	 Percentages noted will adjust for telephone numbers that AOL removes from the LOA lists and implementation plan based on the corresponding “% of AOL
Traffic” stated in Exhibit “D”. 

 Respecting the milestones stated above
for July 1, 2006 and August 1, 2006, Level 3 and AOL agree that the [****] telephone numbers (identified as being “subject to the 3rd party LEC carve-out” in Exhibit “D”) are intended to be ported to satisfy such milestones. In the event the
July 1, 2006 and August 1, 2006 milestones stated above are not met for reasons (i) within AOL’s control or (ii) due to the unreasonable delay of the underlying carriers that supply any of such [****] telephone numbers and
services to AOL’s existing dial-up network services provider in porting-out such telephone numbers to Level 3 based on conflicting customer of record information, the July 1, 2006 and August 1, 2006 milestone will be reduced according
to the “% of AOL Traffic associated with the impacted telephone numbers as stated in Exhibit “D”. In the event the milestones stated above are otherwise not met for reasons not within AOL’s control, AOL shall be entitled, as its
sole remedy for such failure, to a service credit calculated as follows: [****] Level 3 will provide such credits in the month in which AOL provides notification of Total AOL Dial-up Hours as stated in part (b) immediately above. Level 3
reserves the right to audit AOL’s relevant books and records to verify the information AOL has supplied in connection with the foregoing. For avoidance of doubt, the foregoing limitation applies solely with respect to the monetary remedy
available under this Section 11 and AOL is not limited with respect to other remedies provided under the Managed Modem Agreement and this Letter of Agreement, including but not limited to Level 3’s indemnification obligations and AOL’s
rights to terminate Services, to the extent such remedies are triggered by events that also trigger by Level 3’s failure to reach the milestones. 
  

	 	12.	 Monthly Port Volume Adjustments:  The existing Decommissioning Process described in the letter agreement dated October 13, 2005, shall be
deleted and replaced with the following: Beginning October 1, 2006, AOL will provide Level 3 with a non-binding, rolling 90-day forecast of the forecasted quantity of ports needed by AOL for delivery by Level 3 in each “Market” (as such
Markets are identified in Exhibit C hereto). On the first day of each month, AOL will provide a binding notification to Level 3 of the quantity of ports to be added to or removed from each Market on the first day of the next subsequent calendar
month. For example, on July 1st, AOL will provide a non-binding forecast for
anticipated port demand in July, August and September. On August 1st, AOL will (a)
provide Level 3 with a binding notification of the quantity of ports to be added or removed from each Market effective September 1st, and (b) a forecast for anticipated port demand in August, September and October). 

  

	 	13.	 Port Move Rights:  In order to satisfy the Purchase Commitment, as part of the advance forecasting process and notification of monthly port
quantities and associated hours, AOL, subject to other requirements of this Letter Agreement, will have the ability (on five business days prior written notice to Level 3) to redeploy ports across Markets, without any port relocation and/or
installation fee, in order to align the supply of ports with changes in demand across those Markets. 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 

  

 4 

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

  

	 	14.	 ICG Ports:  AOL agrees to renew for a term commencing July 1, 2006 and ending June 30, 2007 (the “ICG Term”) [****]
ICG Ports more specifically to be identified on Exhibit “B” and attached hereto by June 15, 2006 (the “ICG Ports”), such ports to be delivered under the Managed Modem Agreement. The pricing for such ICG Ports shall be
as follows, based on the “Pricing Bracket” of each port identified in Exhibit “B”: 

 Pricing Bracket 1
– [****] ports: [****]/Port/month 
 Pricing Bracket 2 – [****] ports: [****]/Port/month 
 Pricing Bracket 3 – [****] ports: [****]/Port/month 
 Pricing Bracket 4 – [****] ports: [****]/Port/month 
 Respecting the ICG Ports,
Section 12 of this Letter Agreement shall not apply, and Section 13 of this Letter Agreement shall apply, provided that AOL may only move ports within Pricing Brackets (and not between them). For avoidance of doubt, upon expiration of the
ICG Term, AOL shall be entitled to Transition Assistance with respect to the affected ICG Ports. 
  

	 	15.	 Toll Free Managed Modem Services:  The toll free modem service being provided to AOL by Level 3 pursuant to i) the Amendment to the Global
Master Services Agreement for Colocation Space effective as of May 16, 2005 between Level 3 and America Online, Inc., and ii) Amendment No. 6 to Network Services Agreement by and between America Online, Inc and Level 3 Communications, LLC
(successor to Genuity Services, Inc. (BBN Corporation) dated March 21, 2005, shall be further amended to extend the term of such services to be co-terminus with the expiration of the Managed Modem Agreement.

 [****] 
  

	 	17.	 Market Conversion:  Level 3 will use commercially reasonable efforts to complete the conversion from Rate Center-level management of the network
to Market-level management by June 1, 2006. 

  

	 	18.	 Monthly Invoicing:  The [****] ICG Ports and the first [****] other ports will continue to be billed monthly in arrears through the Term (stated
in Section 8 of this Letter Agreement). All other ports will be billed monthly in advance through the Term. 

  

	 	19.	 [****]:  The last sentence of Section 2.2(a) of the Managed Modem Agreement will be modified by changing the number [****].

  

	 	20.	 [****]:  Section 2.2(b) of the Managed Modem Agreement ([****]) is hereby deleted. 

  

	 	21.	 Conversion of Usage Based Ports:  Where this Letter Agreement contemplates the conversion of ports sold on a usage basis to ports charged on a
monthly basis (and vise versa) using an effective monthly usage rate of [****] hours, AOL agrees to review such effective monthly usage rate upon Level 3’s request (but not more often than once per calendar quarter) and adjust the monthly usage
rate to be consistent with AOL’s actual usage of Level 3 fixed rate ports. 

  

	 	22.	 Other existing terms and conditions:  All other terms and conditions in the Managed Modem Agreement, as amended, not specifically addressed
herein will remain in effect. In the event of 

  

 7 

	 	 
any conflicts between the terms of the Managed Modem Agreement and this Letter Agreement, the terms of this Letter Agreement shall govern.

  

	 	23.	 Definitive Agreement:  The parties will work in good faith to complete the terms of a single, new definitive managed modem network services
agreement that will replace/supersede all prior documentation (i.e., prior Level 3, ICG, and Genuity agreements and subsequent letter agreements, amendments, including toll-free dial access, etc.) including the Managed Modem Agreement.

 If you are in agreement with the foregoing, please execute one copy of this letter and return it to the undersigned at
your earliest convenience.
