 3. Amendment to Section 2.6. Section 2.6 of the Term Loan Agreement is hereby amended by
deleting such section in its entirety and substituting in lieu thereof the following: 
 “2.6 Optional
Prepayments. (a) The Borrower may not optionally prepay the Loans at any time prior to the first anniversary of the Closing Date or at any time from and including the Second Amendment Effective Date to but not including the third
anniversary of the Closing Date. The Borrower may at any time and from time to time other than during the periods referred to in the immediately preceding sentence prepay the Loans, in whole or in part, without premium or penalty (except as
otherwise provided herein), upon irrevocable notice delivered to the Administrative Agent no later than 11:00 A.M., New York City time, three Business Days prior thereto in the case of Eurodollar Loans and no later than 11:00 A.M., New York City
time, one Business Day prior thereto in the case of Base Rate Loans, which notice shall specify the date and amount of such prepayment and whether such prepayment is of Eurodollar Loans or Base Rate Loans; provided, that if a Eurodollar Loan
is prepaid on any day other than the last day of the Interest Period applicable thereto, the Borrower shall also pay any amounts owing pursuant to Section 2.16. Upon receipt of any such notice the Administrative Agent shall promptly notify each
Lender thereof. If any such notice is given, the amount specified in such notice shall be due and payable on the date specified therein, together with accrued interest to such date on the amount prepaid. Partial prepayments of Loans shall be in an
aggregate principal amount of $1,000,000 or a whole multiple thereof. 
 (b) Each optional prepayment in respect of the Loans
on or prior to the fifth anniversary of the Closing Date shall be accompanied by a prepayment fee equal to (i) if such prepayment is made (x) on or after the first anniversary of the Closing Date (or on or after the Closing Date in the
case of a prepayment upon a Change of Control) and prior to the second anniversary of the Closing Date or (y) at any time on or after the third anniversary of the Closing Date (or on or after the Second Amendment Effective Date in the case of a
prepayment upon a Change of Control) and prior to the fourth anniversary of the Closing Date, 3% of the principal amount that is the subject of such prepayment, and (ii) if such prepayment is made (x) on or after the second anniversary of
the Closing Date and prior to the Second Amendment Effective Date or (y) at any time on or after the fourth anniversary of the Closing Date and on or prior to the fifth anniversary of the Closing Date, 2% of the principal amount that is the
subject of such prepayment. For purposes of this Section, any prepayment of the Loans upon the refinancing thereof (whether with proceeds of equity or Indebtedness) or upon the occurrence of a Change of Control, or if the Commitments have
automatically terminated and the Loans hereunder have immediately become due and payable pursuant to Section 7 hereof, shall be deemed to be an optional prepayment and entitle the Lender to a Prepayment Premium thereon (to the extent such
prepayment occurs on or prior to the fifth anniversary of the Closing Date). Any prepayment pursuant to Section 2.6(b) after the fifth anniversary of the Closing Date may be made without premium or penalty. 
 (c) Notwithstanding Section 2.6(a) hereof, if any or all of the Loans are prepaid for any reason other than pursuant to
Section 2.7(a) and Section 2.7(b) (it being 

  

 3 








 
understood that prepayment fees with respect to Section 2.7(b) are addressed in Section 2.7(d)) (including, without limitation, due to the
Commitments having automatically terminated and the Loans hereunder having immediately become due and payable pursuant to Section 7 hereof), at any time prior to February 18, 2008, a prepayment fee equal to 5% of the principal amount that
is the subject of such prepayment shall accompany such prepayment.” 
 4. Amendment to Section 2.7(d). Section 2.7(d)
of the Term Loan Agreement is hereby amended by deleting such subsection in its entirety and substituting in lieu thereof the following: 
 “(d) Any prepayment pursuant to Section 2.7(b) on or prior to the fifth anniversary of the Closing Date shall be accompanied by a prepayment fee equal to (i) if such prepayment is made (x) on or
after the first anniversary of the Closing Date and prior to the second anniversary of the Closing Date, 3% of the principal amount of such accepted prepayment or (y) on or after the second anniversary of the Closing Date and prior to the
Second Amendment Effective Date, 2% of the principal amount of such accepted prepayment, or (ii) if such prepayment is made (x) at any time on or after the Second Amendment Effective Date and prior to the third anniversary of the Closing
Date, 5% of the principal amount of such accepted payment, (y) at any time on or after the third anniversary of the Closing Date and prior to the fourth anniversary of the Closing Date, 3% of the principal amount of such accepted prepayment, or
(z) at any time on or after the fourth anniversary of the Closing Date and on or prior to the fifth anniversary of the Closing Date, 2% of the principal amount of such accepted prepayment. Any prepayment pursuant to Section 2.7(b) after
the fifth anniversary of the Closing Date may be made without premium or penalty.” 
 5. Amendment to Section 6.2(b).
Section 6.2(b) of the Term Loan Agreement is hereby amended by (i) deleting clause (ix) and substituting in lieu thereof the following new clause (ix): 
 “(ix) Indebtedness (other than Priority Indebtedness) of Parent or any Restricted Subsidiary of Parent not otherwise permitted
hereunder in an aggregate principal amount which, when aggregated with the principal amount of all other Indebtedness then outstanding and incurred on or after January 16, 2004 pursuant to this clause (ix), clause (ix) of Section 1011
of the Senior Note Indenture or clause (xi) below, does not exceed $200,000,000 at any one time outstanding;”, 
 (ii) deleting the period at the
end of clause (x) and substituting in lieu thereof the following: “; and” and (iii) adding the following new clause (xi): 
 “(xi) Indebtedness of the New Notes Issuer and the New Notes Guarantors in respect of the New Notes (and guarantees thereof) in an aggregate principal amount not to exceed, when combined with any outstanding
principal amount of Indebtedness issued under clause (ix) above, $200,000,000; provided, that (i) the New Notes are issued (A) to refinance or refund or in exchange for then outstanding debt securities of Parent, the Borrower
or a Restricted Subsidiary of Parent or (B) for general corporate purposes, other 

  

 4 








 
than (x) acquisitions (other than acquisitions of subscribers), (y) asset purchases (other than asset purchases constituting the purchase of
subscribers) and (z) dividends paid to a Person other than the Borrower or a Guarantor, (ii) the New Notes do not have any scheduled amortization, do not mature and do not have any mandatory prepayments (other than customary asset sale and
change of control offer requirements), in each case, prior to the date that is at least 91 days following the final maturity of the Loans and (iii) do not have terms and conditions which are materially more restrictive taken as a whole than the
terms and conditions of this Agreement.” 
 6. Amendment to Section 6.12. Section 6.12 of the Term Loan Agreement is
hereby amended by deleting such section in its entirety and substituting in lieu thereof the following: 
 “6.12.
Restriction on Certain Purchases of Indebtedness. No Restricted Subsidiary shall purchase the New Notes or any Indebtedness of Parent or Borrower evidenced by securities that were previously issued or the subject of one or more transactions
registered under the Securities Act of 1933, as amended, except with the net proceeds of, or in exchange for, Indebtedness incurred under Section 6.2(b)(xi).” 
 7. Amendment to Section 7. Section 7 of the Term Loan Agreement is hereby amended by deleting the final paragraph thereof and substituting in lieu thereof the following: 
 “then, and in any such event, (A) if such event is an Event of Default specified in clause (i) or (ii) of paragraph (f) above
with respect to the Borrower, automatically the Commitments shall immediately terminate and the Loans hereunder (with accrued interest thereon) and all other amounts owing under this Agreement and the other Loan Documents, including, without
limitation, any Prepayment Premium payable under Sections 2.6 or 2.7 hereof, shall immediately become due and payable, and (B) if such event is any other Event of Default, with the consent of the Required Lenders, the Administrative Agent may,
or upon the request of the Required Lenders, the Administrative Agent shall, by notice to the Borrower, declare the Loans hereunder (with accrued interest thereon) and all other amounts owing under this Agreement and the other Loan Documents,
including, without limitation, any Prepayment Premium payable under Sections 2.6 or 2.7 hereof, to be due and payable forthwith, whereupon the same shall immediately become due and payable. 
 For the avoidance of doubt, if an Event of Default occurs, then, upon acceleration of the Loans, a premium equivalent to the Prepayment
Premium that would be payable by the Company pursuant to Sections 2.6 or 2.7 hereof upon the date of such prepayment shall also become and be immediately due and payable, to the extent permitted by law, anything in this Agreement to the contrary
notwithstanding (it being understood that any Prepayment Premium owing hereunder shall be calculated according to the date the Loans are repaid and not the date of acceleration).” 
 8. Waiver. The Lenders hereby waive any Default or Event of Default resulting from the Borrower’s failure to deliver the documents required
by Section 5.2(b) of the 

  

 5 








 
Credit Agreement for each of the fiscal quarters ended during the period from September 30, 2005 through September 30, 2006, and any failure to
deliver a notice of Default or Event of Default as a result of such failure. 
 9. Conditions to Effectiveness. This Amendment shall

 (a) This Amendment, duly executed and delivered by a duly authorized officer of each of Parent and the Borrower; 
 (b) An Acknowledgment and Consent, substantially in the form of Exhibit D hereto, duly executed and delivered by each Guarantor;

paid by the Borrower for which invoices have been presented supported by customary documentation (including reasonable fees, disbursements and other charges of counsel to the Administrative Agent and the Lenders, as set forth in paragraph 11 below),
on or before the Amendment Effective Date. 
 10. Representations and Warranties. Parent and the Borrower hereby represent and warrant
to the Administrative Agent and each Lender that (before (other than the events specified in paragraph 8 above) and after giving effect to this Amendment): 
 (a) No Default or Event of Default has occurred and is continuing; and 
 (b) Each of the
representations and warranties made by the Loan Parties in the Loan Documents are true and correct in all material respects on and as of the Amendment Effective Date as if made on and as of such date (except that any representation or warranty which
by its terms is made as of an earlier date shall be true and correct in all material respects as of such earlier date). 
 11. Payment of
Fees and Expenses. 
 (a) In the event that the Required Lenders and the Borrower execute and deliver the Amendment, the
Borrower shall pay to the Administrative Agent, for the ratable benefit of the Lenders consenting to the Amendment on or prior to February 22, 2007, an amendment fee in the amount of 1.50% on the principal amount of each such Lender’s
outstanding Loans immediately prior to the Amendment Effective Date, payable on the Amendment Effective Date.

contemplated hereby. 
 12. Limited Effect. Except as expressly provided hereby, all of the terms and provisions of the Term Loan
Agreement and the other Loan Documents are and shall remain in full force and effect. The amendments contained herein shall not be construed as a waiver or amendment of any other provision of the Term Loan Agreement or the other Loan Documents or
for any purpose except as expressly set forth herein or a consent to any further or future action on the part of the Borrower that would require the waiver or consent of the Administrative Agent or the Lenders. 
 13. GOVERNING LAW; Miscellaneous. (a) THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE
