 [FORM OF REVERSE SIDE OF SENIOR NOTE] 

5 1⁄2% Senior Notes due 2021 

1. Interest  
 Mediacom Broadband LLC, a
Delaware limited liability company, and Mediacom Broadband Corporation, a Delaware corporation (such entities, and their successors and assigns under the Indenture hereinafter referred to, being herein called the “Issuers”), jointly and
severally promise to pay interest on the principal amount of this Note as described below. 
 Interest on the
5 1⁄2% Senior Notes due 2021 (the “Notes”) will accrue at a rate of 5 1⁄2% per annum, payable semiannually, to Holders of record on each April 1 and October 1 immediately preceding the interest payment date on April 15 and October 15 of each year during which
any portion of the Notes shall be outstanding (each an “Interest Payment Date”), commencing October 15, 2014. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 

2. Additional Interest  
 The Holder of
this Note is entitled to the benefits of the Registration Rights Agreement dated as of March 17, 2014 by and among the Issuers and the initial purchasers of the Notes. Capitalized terms used in this paragraph 2 but not defined herein have the
meanings assigned to them in the Registration Rights Agreement. In the event that (i) neither the Exchange Offer Registration Statement nor the Shelf Registration Statement has been filed with the Commission on or prior to the 210th day following the date of the original issuance of the Notes, (ii) the Exchange Offer Registration Statement has not been declared effective on or prior to the 330th day following the date of the original issuance of the Notes, (iii) the Registered Exchange Offer has not been consummated on or prior to the
360th day following the date of the original issuance of the Notes, (iv) notwithstanding the fact that the Issuers have or may consummate a Registered Exchange Offer, the Issuers are required
to file a Shelf Registration Statement and such Shelf Registration Statement is not filed on or prior to the 210th day following the date when the Issuers first become obligated to file such Shelf
Registration Statement, (v) notwithstanding the fact that the Issuers have or may consummate a Registered Exchange Offer, the Issuers are required to file a Shelf Registration Statement and such Shelf Registration Statement is not declared
effective on or prior to the 330th day following the date when the Issuers first become obligated to file such Shelf Registration Statement, or (vi) after the Exchange Offer Registration
Statement or the Shelf Registration Statement has been declared effective, such Registration Statement thereafter ceases to be effective or usable in connection with exchanges or resales, as the case may be, of the Notes at any time that the Issuers
are obligated to maintain the effectiveness thereof pursuant to the Registration Rights Agreement (each such event referred to in clauses (i) through (vi) above being referred to herein as a “Registration Default”), interest
(“Additional Interest”) shall accrue (in addition to stated interest on the Notes) from and including the date on which the first such Registration Default shall occur to but excluding the date on which all Registration Defaults have been
cured, at a rate per annum equal to 0.25% of the principal amount of the Notes; provided, however, that such rate per annum shall increase by an additional 0.25% per annum from and including the 91st day after the first such Registration Default (and each successive 91st day thereafter) unless and until all Registration Defaults have been
cured; provided further, however, that in no event shall the Additional Interest accrue at a rate in excess of 1.00% per annum. The Additional Interest will be payable in cash semiannually in arrears each Interest Payment Date.
The Trustee is not responsible for ascertaining if any Additional Interest is payable under the Registration Rights Agreement. If any Additional Interest is required to be paid, the Issuers will provide the Trustee with an Officers’
Certificate, on or before the relevant Interest Payment Date, setting forth the amount of Additional Interest payable on such Interest Payment Date. Whenever in this Note or in the Indenture a reference is made to interest on the Notes, such
reference shall be deemed to also be a reference to Additional Interest, if any, due on the Notes. 

  
 -32- 








 3. Method of Payment  

By at least 10:00 a.m. (New York City time) on the date on which any principal of, premium, if any, or interest on the Notes is due and
payable, the Issuers shall irrevocably deposit with the Paying Agent via wire transfer of immediately available funds money sufficient to pay such principal, premium, if any, and/or interest. The Issuers will pay interest (except defaulted interest)
to the Persons who are registered Holders of Notes at the close of business on the Regular Record Date next preceding the Interest Payment Date even if the Notes are cancelled, repurchased or redeemed after the record date and on or before the
Interest Payment Date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuers will pay principal, premium, if any, and interest in money of the United States that at the time of payment is legal tender for payment
of public and private debts. All payments with respect to Global Notes and certificated Notes the Holders of which have given written wire transfer instructions to the Paying Agent by no later than five Business Days prior to the relevant payment
date shall be required to be made by wire transfer of immediately available funds to the accounts specified by the Holders thereof. 
 4. Trustee, Paying
Agent and Registrar  
 Law Debenture Trust Company of New York, a New York banking corporation (“Trustee”), will act as
Trustee, and initially as Paying Agent and Note Registrar. The Issuers may appoint and change any Paying Agent, Note Registrar or co-registrar without notice to any Holder of the Notes. 

5. Indenture  
 The Issuers issued the
Notes under an Indenture dated as of March 17, 2014 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), among the Issuers and the Trustee. The terms of the Notes include
those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) (the “TIA”). Capitalized terms used herein and not defined herein have the meanings
ascribed thereto in the Indenture. The Notes are subject to all such terms, and Holders of the Notes are referred to the Indenture and the TIA for a statement of those terms. 

The Notes are unsecured senior obligations of the Issuers initially limited to $200,000,000, and, subject to compliance with the covenants
contained in the Indenture, including Section 1008 as a new Incurrence of Indebtedness by the Issuers, the Issuers may issue Additional Notes having substantially identical terms and conditions as the Initial Notes in unlimited principal
amounts. This Note is one of the Initial Notes referred to in the Indenture. The Notes include the Notes and any Exchange Notes issued in exchange for the Initial Notes or Additional Notes pursuant to the Indenture. The Initial Notes, the Additional
Notes and the Exchange Notes are treated as a single class of securities under the Indenture. The Indenture imposes certain limitations on the Incurrence of Indebtedness by the Issuers, and the Issuers’ Restricted Subsidiaries, the payment of
dividends on, and the purchase or redemption of Equity Interests of Mediacom Broadband LLC and its Restricted Subsidiaries, the sale or transfer of assets, investments of Mediacom Broadband LLC and its Restricted Subsidiaries and transactions with
Affiliates. In addition, the Indenture limits the ability of Mediacom Broadband LLC and its Restricted Subsidiaries to restrict distributions and dividends from Restricted Subsidiaries. 

  
 -33- 








 6. Optional Redemption  

Except as set forth below, the Notes are not redeemable prior to April 15, 2017. Thereafter, the Notes will be redeemable, in whole or in
part, from time to time at the option of the Issuers, on not less than 30 and not more than 60 days’ notice prior to the redemption date by first class mail to each Holder to be redeemed at such Holder’s address appearing in the Note
Register maintained by the Note Registrar at the following redemption prices (expressed as percentages of principal amount) if redeemed during the twelve-month period beginning with April 15 of the year indicated below, in each case together
with accrued and unpaid interest and Additional Interest, if any, thereon to the date of redemption: 
  

					
	 Period
	  	Redemption Price	 
	 2017
	  	 	102.750	% 
	 2018
	  	 	101.375	% 
	 2019 and thereafter
	  	 	100.000	% 

 Notwithstanding the foregoing, at any time prior to April 15, 2017, the Issuers may also redeem the
Notes, in whole or in part from time to time, at the option of the Issuers, upon not less than 30 and not more than 60 days’ notice prior to the redemption date by first class mail to each Holder to be redeemed at such Holder’s address
appearing in the register of Notes maintained by the Note Registrar, at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest and Additional Interest, if
any, thereon, to the date of redemption. 
 In addition, at any time and from time to time, on or prior to April 15, 2017, the Issuers
may redeem up to 40% of the original principal amount of the Notes (calculated to give effect to any issuance of Additional Notes) with the Net Cash Proceeds of one or more Equity Offerings, at a redemption price in cash equal to 105.500% of the
principal to be redeemed plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of redemption; provided that at least 60% of the original principal amount of the Notes (as so calculated) remains outstanding
immediately after each such redemption. Any such redemption will be required to occur within 90 days following the closing of any such Equity Offering. 

7. Selection  
 If fewer than all the
Notes are to be redeemed, the Trustee will select the Notes to be redeemed, if the Notes are listed on a national securities exchange, in accordance with the rules of such exchange or, if the Notes are not so listed, on a pro rata basis or by
lot or by such other method that the Trustee deems to be fair and equitable to Holders; provided that, if a partial redemption is made with the proceeds of any Equity Offering, selection of the Notes or portions thereof for redemption shall
be made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to DTC procedures). If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state
the portion of the principal amount thereof to be redeemed and a new Note or Notes in principal amount equal to the unredeemed principal portion thereof will be issued; provided that no Notes of a principal amount of $2,000 or less shall be
redeemed in part. On and after the redemption date, interest will cease to accrue on Notes or portions thereof called for redemption as long as the Issuers have deposited with the Paying Agent for the Notes funds in satisfaction of the applicable
redemption price pursuant to the Indenture. 

  
 -34- 








 8. Change of Control  

Upon the occurrence of a Change of Control, each Holder shall have the right to require the Issuers to repurchase all or any part of such
Holder’s Notes pursuant to a Change of Control Offer at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase (subject to the right of Holders of
record on the relevant record date to receive interest due on the relevant Interest Payment Date). 
 9. Denominations; Transfer; Exchange  

The Notes are in registered form without coupons in denominations of principal amount of $2,000 and integral multiples of $1,000 in excess
thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Note Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. The Note Registrar need not register the transfer of or exchange of (i) any Note selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) for a
period beginning 15 days before the mailing of a notice of redemption of Notes to be redeemed and ending on the date of such selection or (ii) any Notes for a period beginning 15 days before an Interest Payment Date and ending on such Interest
Payment Date. 
 10. Persons Deemed Owners  

The registered Holder of this Note may be treated as the owner of it for all purposes. 

11. Unclaimed Money  
 If money for the
payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Issuers at their written request unless an abandoned property law designates another Person. After any such payment,
Holders entitled to the money must look only to the Issuers and not to the Trustee for payment. 
 12. Defeasance  

Subject to certain conditions set forth in the Indenture, the Issuers at any time may terminate some or all of their obligations under the
Notes and the Indenture if the Issuers deposit with the Trustee money or U.S. Government Obligations for the payment of principal, premium, if any, and interest on the Notes to redemption or maturity, as the case may be. The Issuers in their sole
discretion can defease the Notes. 
 13. Amendment, Waiver  

Subject to certain exceptions set forth in the Indenture, (i) the Indenture, the Notes or the Restricted Subsidiary Guarantees may be
amended with the written consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and (ii) any default or noncompliance with any provision may be waived with the consent of the Holders of a
majority in principal amount of the outstanding Notes. Without the consent of any Noteholder, the Issuers and the Trustee may amend the Indenture or the Notes to cure any ambiguity, omission, defect or inconsistency, or to comply with Article Eight
of the Indenture, or to provide for uncertificated Notes in addition to or in place of certificated Notes or to add guarantees with respect to the Notes or to secure the Notes, or to add additional covenants or surrender rights and powers conferred
on the Issuers, or to comply with any request of the SEC in connection with qualifying the Indenture under the TIA, or to make any change that does not adversely affect the rights of any Noteholder, or to conform the text of the Indenture or the
Notes to any provision of the “Description of the Notes” in the Offering Memorandum. 

  
 -35- 








 14. Defaults and Remedies  

Under the Indenture, Events of Default include (i) a default in the payment of principal of, or premium, if any, on the Notes when due at
their Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise, (ii) a default in any payment of interest or Additional Interest, if any, on the Notes when due, continued for 30 days, (iii) the
failure by either of the Issuers or the Guarantors to comply for 60 days after written notice by Holders of not less than 25% in principal amount of the Notes then outstanding with any other covenant, representation, warranty or other agreement
contained in the Indenture or the Notes, (iv) default in the payment at maturity (continued for the longer of any applicable grace period, extension, forbearance or other similar period or 30 days) of any Indebtedness aggregating $25,000,000 or
more of the Issuers or any Significant Subsidiary or any group of Restricted Subsidiaries of Mediacom Broadband LLC which, if merged into each other, would constitute a Significant Subsidiary, or the acceleration of any such Indebtedness which
default shall not be cured or waived, or such acceleration shall not be rescinded or annulled, within 30 days after written notice thereof by the Holders of not less than 25% in principal amount of the Notes then outstanding, (v) any final
judgment or judgments for the payment of money in excess of $25,000,000 (net of amounts covered by insurance) is rendered against the Issuers or a Significant Subsidiary or any group of Restricted Subsidiaries of Mediacom Broadband LLC, which, if
merged into each other, would constitute a Significant Subsidiary, and such judgment or judgments remain undischarged for any period of 60 consecutive days, during which a stay of enforcement of such judgment shall not be in effect, or (vi) the
guarantee of any Guarantor ceasing to be in full force and effect (except as contemplated by the terms of the Indenture). Certain events of bankruptcy or insolvency are Events of Default which will result in the Notes being due and payable
immediately upon the occurrence of such Events of Default. The failure by any Restricted Subsidiary Guarantee to be in full force and effect (except as contemplated by the terms thereof) or any Guarantor to deny or disaffirm its obligations under
the Indenture or any Restricted Subsidiary Guarantee shall also be an Event of Default. 
 If an Event of Default occurs and is continuing
(other than an Event of Default resulting from certain events of bankruptcy, insolvency or reorganization), the Trustee or the Holders of not less than 25% in principal amount of the outstanding Notes may declare the principal of and accrued and
unpaid interest, if any, on all the Notes to be due and payable immediately. Upon such a declaration, such principal and accrued and unpaid interest shall be due and payable immediately. Under limited circumstances, the Holders of a majority in
principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences. Notwithstanding the foregoing, in the case of an Event of Default resulting from certain events of bankruptcy, insolvency or
reorganization, all outstanding Notes shall be due and payable immediately without further action or notice. 
 Holders of the Notes may not
enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority
in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default in payment
of principal or of premium, if any, or interest or Additional Interest, if any, on the Notes) if the Trustee determines that withholding notice is in the best interest of the Holders.

 ARTICLE THREE 

THE NOTES 
 SECTION 301.
Title and Terms. 
 The aggregate principal amount of Notes which may be authenticated and delivered under this Indenture on the date
of this Indenture is limited to $200,000,000 aggregate principal amount at maturity of Initial Notes. The Notes may be issued in more than one series. All Notes of any one series shall be substantially identical except as to denomination. 

The Issuers may from time to time after the date of this Indenture issue additional Notes (the “Additional Notes”) having
substantially identical terms and conditions to the Initial Notes in unlimited principal amount so long as (i) the Incurrence of Indebtedness represented by such Additional Notes is at such time permitted by Section 1008 and (ii) such
Additional Notes are issued in compliance with the other applicable provisions of this Indenture. Any Additional Notes shall constitute part of the same issue as the Initial Notes offered on the date of this Indenture and shall be treated as Notes
for all purposes of this Indenture. With respect to any Additional Notes issued after the date of this Indenture (except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant
to Section 304, 305, 306, 307, 310, 906, 1012, 1013 or 1108, pursuant to an Exchange Offer), there shall be established (a) in or pursuant to a Committee Resolution and (b)(i) set forth or determined in the manner provided in an
Officer’s Certificate or (ii) established pursuant to one or more indentures supplemental hereto, prior to the issuance of such Additional Notes: 

(i) whether such Additional Notes shall be issued as part of a new or existing series of Notes and the title of such Additional
Notes (which shall distinguish the Additional Notes of the series from Notes of any other series); 
 (ii) the aggregate
principal amount of such Additional Notes which may be authenticated and delivered under this Indenture, 
 (iii) the issue
price and issuance date of such Additional Notes, including the date from which interest on such Additional Notes shall accrue; and 

(iv) if applicable, that such Additional Notes shall be issuable in whole or in part in the form of one or more Global Notes
and, in such case, the respective depositaries for such Global Notes, the form of any legend or legends which shall be borne by such Global Notes; and any circumstances in which any such Global Notes may be exchanged in whole or in part for
Additional Notes registered, or any transfer of such Global Notes in whole or in part may be registered, in the name or names of Persons other than the depositary for such Global Notes or a nominee thereof. 

If any of the terms of any Additional Notes are established by action taken pursuant to a Committee Resolution, a copy of an appropriate
record of such action shall be certified by the Secretary or any Assistant Secretary of the Issuers and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate or the indenture supplemental hereto setting forth the
terms of the Additional Notes. 

  
 -43- 








 The Initial Notes and the Additional Notes shall be known and designated as the “5 1⁄2% Senior Notes due 2021,” and the Exchange Notes shall be known and designated as the “5 1⁄2% Senior Notes due 2021,” in each case, of the Issuers. Interest on the Notes will accrue at a rate per annum of
5 1⁄2% and will be payable semiannually in cash and in arrears to the Holders of record on each April 1 and October 1 immediately preceding the
interest payment date on April 15 and October 15 of each year during which any portion of the Notes shall be outstanding (each, an “Interest Payment Date”), commencing October 15, 2014. Interest on the Notes will accrue from
the most recent interest payment date to which interest has been paid or, if no interest has been paid, from March 17, 2014. All references to the principal amount of the Notes herein are references to the principal amount at final maturity.
Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months, until the principal thereof is paid or duly provided for Interest on any overdue principal, interest (to the extent lawful) or premium, if any, shall be
payable on demand. 
 The principal of (and premium, if any) and interest on the Notes shall be payable at the office or agency of the
Issuers maintained for such purpose in the Borough of Manhattan, The City of New York, or at such other office or agency of the Issuers as may be maintained for such purpose; provided, however, that, at the option of the Issuers,
interest may be paid by check mailed to addresses of the Persons entitled thereto as such addresses shall appear on the Note Register. 

Holders shall have the right to require the Issuers to purchase their Notes, in whole or in part, in the event of a Change of Control pursuant
to Section 1012 and in connection with an Excess Proceeds Offer as provided in Section 1013. 
 The Notes shall be redeemable as
provided in Article Eleven and in the Notes. 
 SECTION 302. Denominations. 

The Notes shall be issuable only in fully registered form, without coupons, and only in denominations of $2,000 and any integral multiples of
$1,000 in excess thereof. 
 SECTION 303. Execution, Authentication, Delivery and Dating. 

The Notes shall be executed by each of the Issuers by two Officers. The signature of any Officer on the Notes may be manual or facsimile
signatures of the present or any future such authorized officer and may be imprinted or otherwise reproduced on the Notes. 
 Notes bearing
the manual or facsimile signatures of individuals who were at any time the proper officers of the Issuers (or in the case of Mediacom Broadband LLC, of its sole member) shall bind the Issuers, notwithstanding that such individuals or any of them
have ceased to hold such offices prior to the authentication and delivery of such Notes or did not hold such offices at the date of such Notes. 

At any time and from time to time after the execution and delivery of this Indenture, the Issuers may deliver Initial Notes or Additional
Notes executed by the Issuers to the Trustee for authentication, together with an order for the authentication and delivery of such Notes (the “Authentication Order”) directing the Trustee to authenticate the Notes and certifying that all
conditions precedent to the issuance of Notes contained herein have been fully complied with, and the Trustee in accordance with such Authentication Order shall authenticate and deliver such Initial Notes or Additional Notes. Upon receipt of the
Authentication Order, the Trustee shall authenticate for original issue Exchange Notes; provided that such Exchange Notes shall be issuable only upon the valid surrender for cancellation of Initial Notes or Additional Notes of a like
aggregate principal amount. The Trustee shall be entitled to receive an Officers’ Certificate and an Opinion of Counsel of the Issuers that it may reasonably request in connection with such authentication of Notes. Such order shall specify the
amount of Notes to be authenticated and the date on which the original issue of Initial Notes, Additional Notes or Exchange Notes is to be authenticated. 

  
 -44- 








 Each Note shall be dated the date of its authentication. 

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that
such Note has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. 
 In case either of the
Issuers, pursuant to Article Eight, shall be consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise dispose of substantially all of its assets to any Person, and the successor Person resulting from such
consolidation, or surviving such merger, or into which such Issuer shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid, shall have executed an indenture supplemental hereto
with the Trustee pursuant to Article Eight, any of the Notes authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may, from time to time, at the request of the successor Person, be
exchanged for other Notes executed in the name of the successor Person with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Notes surrendered for such exchange and of like principal amount;
and the Trustee, upon the Issuers’ Request of the successor Person, shall authenticate and deliver Notes as specified in such request for the purpose of such exchange. If Notes shall at any time be authenticated and delivered in any new name of
a successor Person pursuant to this Section 303 in exchange or substitution for or upon registration of transfer of any Notes, such successor Person, at the option of the Holders but without expense to them, shall provide for the exchange of
all Notes at the time outstanding for Notes authenticated and delivered in such new name. 
 The Trustee may appoint an authenticating agent
acceptable to the Issuers to authenticate Notes on behalf of the Trustee. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such authenticating agent. An authenticating agent has the same rights as any Note Registrar or Paying Agent to deal with the Issuers and their Affiliates hereunder. 

SECTION 304. Temporary Notes. 

Pending the preparation of definitive Notes, the Issuers may execute, and upon Authentication Order the Trustee shall authenticate and deliver,
temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination. Temporary Notes shall be substantially of the tenor of the definitive Notes in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as conclusively evidenced by their execution of such Notes. 

If temporary Notes are issued, the Issuers will cause definitive Notes to be prepared without unreasonable delay. After the preparation of
definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Issuers designated for such purpose pursuant to Section 1002, without charge to the Holder.
Upon surrender for cancellation of any one or more temporary Notes, the Issuers shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Notes of authorized denominations. Until so
exchanged, the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as definitive Notes. 

  
 -45- 








 SECTION 305. Registration, Registration of Transfer and Exchange. 

The Issuers shall cause to be kept at the Office of the Note Registrar a register (the register maintained in such office or in any other
office or agency designated pursuant to Section 1002 being herein sometimes referred to as the “Note Register”) in which, subject to such reasonable regulations as they may prescribe, the Issuers shall provide for the registration of
Notes and of transfers of Notes. The Note Register shall be in written form or any other form capable of being converted into written form within a reasonable time. At all reasonable times, the Note Register shall be open to inspection by the
Trustee. Law Debenture Trust Company of New York is hereby initially appointed as security registrar (in which capacity, together with any successor of Law Debenture Trust Company of New York in such capacity, the “Note Registrar”) for the
purpose of registering Notes and transfers of Notes as herein provided. 
 Upon surrender for registration of transfer of any Note at the
office or agency of the Issuers designated pursuant to Section 1002, the Issuers shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized
denomination or denominations of a like aggregate principal amount. 
 Furthermore, any Holder of a Global Note shall, by acceptance of such
Global Note, agree that transfers of beneficial interest in such Global Note may be effected only through a book-entry system maintained by the Holder of such Global Note (or its agent), and that ownership of a beneficial interest in the Note shall
be required to be reflected in a book entry. 
 At the option of the Holder, Notes may be exchanged for other Notes of any authorized
denomination (not less than $2,000) and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange (including an exchange of Initial Notes or
Additional Notes for Exchange Notes), the Issuers shall execute, and the Trustee shall upon receipt of an Authentication Order and any other documents required to be delivered to the Trustee pursuant to Section 303 in connection with
authentication of Notes, authenticate and deliver, the Notes which the Holder making the exchange is entitled to receive; provided that (i) no exchange of Initial Notes for Exchange Notes shall occur until an Exchange Offer Registration
Statement shall have been declared effective by the SEC, the Trustee shall have received an Officers’ Certificate confirming that the Exchange Offer Registration Statement has been declared effective by the SEC and the Initial Notes to be
exchanged for the Exchange Notes shall be cancelled by the Trustee and (ii) no exchange of Additional Notes for Exchange Notes shall occur until a registration statement shall have been declared effective by the SEC, the Trustee shall have
received an Officers’ Certificate confirming that the registration statement has been declared effective by the SEC and the Additional Notes to be exchanged for the Exchange Notes shall be cancelled by the Trustee. 

All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Issuers, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. 

Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Issuers or the Note Registrar)
be duly endorsed, or be accompanied by a written instrument of transfer, in form satisfactory to the Issuers and the Note Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. 

No service charge shall be made for any registration of transfer or exchange or redemption of Notes, but the Issuers may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Section 304, 906, 1012, 1013 or 1108, not involving any
transfer. 

  
 -46- 








 The Note Register shall be in written form in the English language or in any other form including
computerized records, capable of being converted into such form within a reasonable time. 
 SECTION 306. Book-Entry Provisions for
Global Notes. 
 (a) Each Global Note initially shall (i) be registered in the name of the Depositary for such Global Note or the
nominee of such Depositary, (ii) be delivered to the Trustee as custodian for such Depositary and (iii) bear legends as set forth in Section 202. 

(b) Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any
Global Note held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Note, and the Depositary may be treated by the Issuers, the Trustee and any agent of the Issuers or the Trustee as the absolute owner of such
Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuers, the Trustee or any agent of the Issuers or the Trustee from giving effect to any written certification, proxy or other authorization
furnished by the Depositary or shall impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note. 

(c) Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to the Depositary, its successors
or their respective nominees. Interests of beneficial owners in a Global Note may be transferred in accordance with the rules and procedures of the Depositary and the provisions of Section 307. If required to do so pursuant to any applicable
law or regulation, beneficial owners may obtain Notes in definitive form (“Certificated Notes”) in exchange for their beneficial interests in a Global Note upon written request in accordance with the Depositary’s and the Note
Registrar’s procedures. In addition, Certificated Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Note if (i) the Depositary notifies the Issuers that it is unwilling or unable to
continue as Depositary for such Global Note or the Depositary ceases to be a clearing agency registered under the Exchange Act, at a time when the Depositary is required to be so registered in order to act as Depositary, and in each case a successor
depositary is not appointed by the Issuers within 90 days of such notice or (ii) an Event of Default has occurred and is continuing and the Note Registrar has received a request from the Depositary. 

(d) In connection with any transfer of a portion of the beneficial interest in a Global Note pursuant to subsection (b) of this Section to
beneficial owners who are required to hold Certificated Notes, the Note Registrar shall reflect on its books and records the date and a decrease in the principal amount of such Global Note in an amount equal to the principal amount of the beneficial
interest in the Global Note to be transferred, and the Issuers shall execute, and the Trustee shall authenticate and deliver, one or more Certificated Notes of like tenor and amount. 

(e) In connection with the transfer of an entire Global Note to beneficial owners pursuant to subsection (b) of this Section, such Global
Note shall be deemed to be surrendered to the Trustee for cancellation, and the Issuers shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in
such Global Note, an equal aggregate principal amount of Certificated Notes of authorized denominations. 
 (f) Any Certificated Note
delivered in exchange for an interest in a Global Note pursuant to subsection (c) or subsection (d) of this Section shall, except as otherwise provided by paragraph (c) of Section 307, bear the applicable legend regarding
transfer restrictions applicable to the Certificated Note set forth in Section 202. 

  
 -47- 








 (g) The registered Holder of a Global Note may grant proxies and otherwise authorize any person,
including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes. 

SECTION 307. Special Transfer Provisions.

reliance on Rule 144A and acknowledges that it has received such information regarding the Issuers as the undersigned has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is
relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; 
 (ii) a
transfer of a Rule 144A Note or an Institutional Accredited Investor Note or a beneficial interest therein to an institutional accredited investor shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set

(iii) a transfer of a Rule 144A Note or an Institutional Accredited Investor Note or a beneficial interest therein to a
Non-U.S. Person shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth in Section 309 from the transferor and, if requested by the Issuers or the Trustee, the delivery of certification and/or
other information satisfactory to each of them; and

provided by Rule 144A; 
 (ii) a transfer of a Regulation S Note or a beneficial interest therein to an institutional
accredited investor shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth in Section 308 from the proposed transferee and, if requested by the Issuers or the Trustee, the delivery of
certification and/or other information satisfactory to each of them; 
 (iii) a transfer of a Regulation S Note or a
beneficial interest therein to a Non-U.S. Person shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth in Section 309 from the transferor and, if requested by the Issuers or the Trustee,

transfer, exchange or replacement of Notes not bearing the Private Placement Legend, the Note Registrar shall deliver Notes that do not bear the Private Placement Legend. Upon the transfer, exchange or replacement of Notes bearing the Private
Placement Legend, the Note Registrar shall deliver only Notes that bear the Private Placement Legend unless there is delivered to the Note Registrar an Opinion of Counsel reasonably satisfactory to the Issuers and the Trustee to the effect that
neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act. 

(d) General. By its acceptance of any Note bearing the Private Placement Legend, each Holder of such a Note acknowledges the
restrictions on transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Note only as provided in this Indenture.

dates on which the Distribution Compliance Period terminates. 
 The Note Registrar shall retain copies of all letters, notices and other
written communications received pursuant to Section 306 or this Section 307. The Issuers shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of
reasonable written notice to the Note Registrar. 
 (f) No Obligation of the Trustee. 

(i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in the
Depositary or other Person with respect to any ownership interest in the Notes, with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof or with respect to the delivery to any participant,
member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and
all payments to be made to Holders under the Notes shall be given or made only to the registered Holders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note in global form
shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustee may rely and shall be fully protected and indemnified pursuant to Section 607 in relying upon information furnished by
the Depositary with respect to any beneficial owners, its members and participants. 
 (ii) The Trustee shall have no obligation or duty to
monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including without limitation any transfers between or
among Depositary participants, members or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation of evidence as are expressly required by, and to do so if and when expressly required by, the
terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

The undersigned represents and warrants to you that: 

(1) We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the
Securities Act of 1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of an institutional “accredited investor,” and we are acquiring the Notes not with a view to, or for offer or sale in
connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Notes and invest in or
purchase securities similar to the Notes in the normal course of our business. We and any accounts for which we are acting are each able to bear the economic risk of our or its investment. 

(2) We understand that the Notes have not been registered under the Securities Act and, unless so registered, may not be sold
except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Notes to offer, sell or otherwise transfer such Notes prior to the expiration of the holding period
applicable thereto under Rule 144(k) under the Securities Act which is applicable to this security (the “Resale Restriction Termination Date”) other than (1) to the Issuers or their respective Subsidiaries, (2) so long as this
security is eligible for resale pursuant to Rule 144A under the Securities Act (“Rule 144A”), to a person who the seller reasonably believes is a “qualified institutional buyer” within the meaning of Rule 144A purchasing for its
own account or for the account of a qualified institutional buyer, in each case to whom notice is given that the resale, pledge or other transfer is being made in reliance on Rule 144A (as indicated by the box checked by the transferor on the
certificate of transfer on the reverse of the security if this security is not in book-entry form), (3) inside the United States to an institutional “accredited investor” (as defined in Rule 501(a) (1), (2), (3) or (7) under
the Securities Act) that, prior to such transfer, furnishes to the Trustee a signed letter containing various representations and agreements (the form of which letter can be obtained from the trustee), (4) to a non-“U.S. Person” in an
“offshore transaction” (as such terms are defined in Regulation S under the Securities Act) in accordance with Regulation S under the Securities Act (as indicated by the box checked by the transferor on the certificate of transfer on the
reverse of the security if the security is not in book-entry form), (5) pursuant to any other available exemption from the registration requirements of the Securities Act, including the exemption provided by Rule 144 under the Securities Act,
if available, or (6) pursuant to an effective registration statement under the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of its property or the property of such investor account or
accounts be at all times within its or their control, and subject to the right of the Issuers or the Trustee for the Notes prior to any such sale, pledge or other transfer pursuant to clause (5) above to require the delivery of an opinion of
counsel, certifications and/or other information satisfactory to each of them.

	 	Re:	Mediacom Broadband LLC and Mediacom Broadband 

 Corporation (the “Issuers”) 5 1⁄2% Senior Notes due 2021 (the “Notes”) 
 Ladies and
Gentlemen: 
 In connection with our proposed sale of $            aggregate
principal amount of the Notes, we confirm that such sale has been effected pursuant to and in accordance with Regulation S under the United States Securities Act of 1933, as amended (the “Securities Act”), and, accordingly, we represent
that: 
 (a) the offer of the Notes was not made to a person in the United States; 

(b) either (i) at the time the buy order was originated, the transferee was outside the United States or we and any person
acting on our behalf reasonably believed that the transferee was outside the United States or (ii) the transaction was executed in, on or through the facilities of a designated off-shore securities market and neither we nor any person acting on
our behalf knows that the transaction has been pre-arranged with a buyer in the United States; 
 (c) no directed selling
efforts have been made in the United States in contravention of the requirements of Rule 903(b) or Rule 904(b) of Regulation S, as applicable; and 

(d) the transaction is not part of a plan or scheme to evade the registration requirements of the Securities Act. 

In addition, if the sale is made during a distribution compliance period and the provisions of Rule 903(c)(3) or Rule 904(c)(1) of Regulation
S are applicable thereto, we confirm that such sale has been made in accordance with the applicable provisions of Rule 903(c)(3) or Rule 904(c)(1), as the case may be.

 You and the Issuers are entitled to rely upon this letter and are irrevocably authorized to
produce this letter or a copy hereof to any interested party in any administrative or legal proceedings or official inquiry with respect to the matters covered hereby. Terms used in this certificate have the meanings set forth in Regulation S.

 SECTION 310. Mutilated, Destroyed, Lost and Stolen Notes. 

If (i) any mutilated Note is surrendered to the Trustee, or (ii) the Issuers and the Trustee receive evidence to their satisfaction
of the destruction, loss or theft of any Note, and there is delivered to the Issuers and the Trustee such security or indemnity, in each case, as may be required by them to save each of them harmless, then, in the absence of notice to the Issuers or
the Trustee that such Note has been acquired by a bona fide purchaser, the Issuers shall execute and upon Authentication Order the Trustee shall authenticate and deliver, in exchange for any such mutilated Note or in lieu of any such destroyed, lost
or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously outstanding. 
 In case any such
mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Issuers in their discretion may, instead of issuing a new Note, pay such Note. 

Upon the issuance of any new Note under this Section, the Issuers may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) in connection therewith. 

Every new Note issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Issuers and any other obligor upon the Notes, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture
equally and proportionately with any and all other Notes duly issued hereunder. 
 The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes. 

SECTION 311. Payment of Interest; Interest Rights Preserved. 

Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name such Note (or one or more predecessor Notes) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Issuers maintained for such purpose pursuant to Section 1002;
provided, however, that each installment of interest may at the Issuers’ option be paid by (i) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to
Section 312, to the address of such Person as it appears in the Note Register or (ii) wire transfer to an account located in the United States maintained by the payee. Whenever in this Indenture or the Notes a reference is made to interest
on the Notes, such reference shall be deemed to also be a reference to Additional Interest, if any, due on the Notes. 

  
 -53- 








 Any interest on any Note which is payable, but is not paid when the same becomes due and payable
and such nonpayment continues for a period of 30 days shall forthwith cease to be payable to the Holder on the Regular Record Date by virtue of having been such Holder, and such defaulted interest and (to the extent lawful) interest on such
defaulted interest at the rate borne by the Notes (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) shall be paid by the Issuers, at their election in each case, as provided in clause
(a) or (b) below: 
 (a) The Issuers may elect to make payment of any Defaulted Interest to the Persons in whose
names the Notes (or their respective predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuers shall notify the Trustee
in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date (not less than 30 days after such notice) of the proposed payment (the “Special Interest Payment Date”), and at the same time the Issuers shall
deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment,
such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a record date (the “Special Record Date”) for the payment of such
Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the Special Interest Payment Date and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly
notify the Issuers of such Special Record Date, and in the name and at the expense of the Issuers, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be
given in the manner provided for in Section 106, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having
been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the close of business on such Special Record Date and shall
no longer be payable pursuant to the following clause (b). 
 (b) The Issuers may make payment of any Defaulted Interest in
any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuers to the Trustee of the
proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the foregoing
provisions of this Section, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such
other Note. 
 SECTION 312. Persons Deemed Owners. 

Prior to the due presentment of a Note for registration of transfer, the Issuers, the Trustee and any agent of the Issuers or the Trustee may
treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of (and premium, if any) and (subject to Sections 305 and 311) interest on such Note and for all other purposes
whatsoever, whether or not such Note be overdue, and none of the Issuers, the Trustee nor any agent of the Issuers or the Trustee shall be affected by notice to the contrary. 

  
 -54- 








 SECTION 313. Cancellation. 

All Notes surrendered for payment, redemption, registration of transfer, exchange or cancellation shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. All Notes surrendered for payment, redemption, registration of transfer, exchange or cancellation to the Trustee shall promptly be cancelled by it. If the Issuers
shall acquire any of the Notes other than as set forth in the first sentence of this Section 313, the acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are
surrendered to the Trustee for cancellation pursuant to this Section 313. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by this Indenture. All
cancelled Notes held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures. 
 SECTION 314.
Computation of Interest. 
 Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. 

SECTION 315. CUSIP Numbers. 

The Issuers in issuing Notes may use “CUSIP” numbers (if then generally in use) in addition to serial numbers; if so, the Trustee
shall use such “CUSIP” numbers in addition to serial numbers in notices of redemption and repurchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such
CUSIP numbers, either as printed on the Notes or as contained in any notice of a redemption or repurchase and that reliance may be placed only on the serial or other identification numbers printed on the Notes, and any such redemption or repurchase
shall not be affected by any defect in or omission of such CUSIP numbers. The Issuers will promptly notify the Trustee of any change in the CUSIP numbers. 

SECTION 316. Note Registrar and Paying Agent. 

The Issuers may have one or more co-registrars and one or more additional paying agents. The term “Note Registrar” includes any
co-registrar, and the term “Paying Agent” includes any additional paying agent. 
 The Issuers shall enter into an appropriate
agency agreement with any Note Registrar or Paying Agent not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuers shall notify
the Trustee of the name and address of any such agent. The Issuers may appoint and change any Paying Agent, Note Registrar or co-registrar without notice to any Holder of the Notes. If the Issuers fail to appoint or maintain another entity as Note
Registrar or Paying Agent, the Trustee shall act as such. Mediacom Broadband LLC or any of its Subsidiaries may act as Paying Agent or Note Registrar.

 ARTICLE FOUR 

SATISFACTION AND DISCHARGE 

SECTION 401. Satisfaction and Discharge of Indenture. 

This Indenture shall upon the Issuers’ Request cease to be of further effect (except as to surviving rights of registration of transfer or
exchange of Notes expressly provided for herein or pursuant hereto) and the Trustee, at the expense of the Issuers, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture when 

(i) either 

(A) all Notes theretofore authenticated and delivered (other than (1) Notes which have been lost, stolen or destroyed and
which have been replaced or paid as provided in Section 310 and (2) Notes for whose payment money has theretofore been deposited in trust with the Trustee or any Paying Agent or segregated and held in trust by the Issuers and thereafter
repaid to the Issuers or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or 

(B) all Notes not theretofore delivered to the Trustee for cancellation 

(1) have become due and payable by reason of the making of a notice of redemption or otherwise; or 

(2) will become due and payable at their Stated Maturity within one year; or 

(3) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Issuers, 
 and the Issuers in the case of (1), (2) or (3) above,
have irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose an amount in cash or U.S. Government Obligations sufficient, in the opinion of a nationally recognized firm of independent public
accountants selected by the Issuers, to pay and discharge the entire indebtedness on such Notes not theretofore delivered to the Trustee for cancellation, for principal of (and premium, if any) and interest to the date of such deposit (in the case
of Notes which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; 
 (ii) no
Default or Event of Default with respect to this Indenture or the Notes shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit and such deposit will not result in a breach or violation of, or
constitute a default under, any other instrument or agreement to which the Issuers is a party or by which it is bound; 

(iii) the Issuers have paid or caused to be paid all sums payable hereunder by the Issuers in connection with all the Notes
including all fees and expenses of the Trustee; 

  
 -56- 








 (iv) the Issuers have delivered irrevocable instructions to the Trustee to apply
the deposited money toward the payment of such Notes at maturity or the Redemption Date, as the case may be; and 
 (v) the
Issuers have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture and the termination of the
Issuers’ obligation hereunder have been satisfied. 
 Notwithstanding the satisfaction and discharge of this Indenture, the obligations
of the Issuers to the Trustee under Section 607 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (i) of this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive any such satisfaction and discharge. 
 SECTION 402. Application of Trust Money. 

Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall
be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuers acting as their own Paying Agent) as the Trustee may determine,
to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law. 

If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 401 by reason of
any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuers’ obligations under this Indenture and the Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Section 401; provided that if the Issuers have made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of its obligations, the
Issuers shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent. 

ARTICLE FIVE 
 REMEDIES

 SECTION 501. Events of Default. 

“Event of Default,” wherever used herein, means any one of the following events (whatever the reason for such Event of Default and

(i) a default in the payment of principal of or premium on any Note when due at its Stated Maturity, upon optional redemption,

if any, on any Note when due, continued for 30 days;

(iv) default in the payment at maturity (continued for the longer of any applicable grace, extension, forbearance or other
similar period or 30 days) of any Indebtedness aggregating $25,000,000 or more of the Issuers or any Significant Subsidiary or any group of Restricted Subsidiaries of Mediacom Broadband LLC which, if merged into each other, would constitute a
Significant Subsidiary, or the acceleration of any such Indebtedness which default shall not be cured or waived, or such acceleration shall not be rescinded or annulled, within 30 days after the written notice thereof by the Holders of not less than
25% in principal amount of the Notes then outstanding; 
 (v) any final judgment or judgments for the payment of money in
excess of $25,000,000 (net of amounts covered by insurance) is rendered against the Issuers or any Significant Subsidiary or any group of Restricted Subsidiaries of Mediacom Broadband LLC, which, if merged into each other, would constitute a
Significant Subsidiary, and shall not be discharged for any period of 60 consecutive days, during which a stay of enforcement of such judgment shall not be in effect; 

(vi) either of the Issuers or a Significant Subsidiary or any group of Restricted Subsidiaries of Mediacom Broadband LLC which,
if merged into each other, would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law: 

(A) commences a voluntary case; 

(B) consents to the entry of an order for relief against it in an involuntary case; 

(C) consents to the appointment of a custodian of it or for all or substantially all of its property; 

(D) makes a general assignment for the benefit of its creditors; 

or takes any comparable action under any foreign laws relating to insolvency; or 

(vii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(A) is for relief against either of the Issuers or any Significant Subsidiary or any group of Restricted Subsidiaries of
Mediacom Broadband LLC which, if merged into each other, would constitute a Significant Subsidiary, in an involuntary case; 

(B) appoints a custodian of either of the Issuers or any Significant Subsidiary or any group of Restricted Subsidiaries of
Mediacom Broadband LLC which, if merged into each other, would constitute a Significant Subsidiary, for all or substantially all of its property; or 

  
 -58- 








 (C) orders the winding up or liquidation of either of the Issuers or any
Significant Subsidiary or any group of Restricted Subsidiaries of Mediacom Broadband LLC which, if merged into each other, would constitute a Significant Subsidiary; 

and, in the case of each of clauses (A), (B) and (C), such order or decree remains unstayed and in effect for 60 consecutive days; or any
similar relief is granted under any foreign laws relating to insolvency and the applicable order or decree remains unstayed and in effect for 90 consecutive days; or 

(viii) the guarantee of any Guarantor ceases to be in full force and effect (except as contemplated by the terms of this
Indenture) or any Guarantor denies or disaffirms its obligations under this Indenture or the guarantee of such Guarantor. 
 The Issuers are
required to deliver to the Trustee, within 120 days after the end of each fiscal year of Mediacom Broadband LLC, in accordance with Section 1016, an Officers’ Certificate stating whether or not the signers know of any Event of Default, a
description of the Event of Default and its status and what action the Issuers are taking or propose to take in respect thereof. 
 If a
Default occurs and is continuing and is known to the Trustee, the Trustee must mail to each Holder, in accordance with Section 602, notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of
principal of, premium, if any, or interest on any Note, the Trustee may withhold notice if and so long as it in good faith determines that withholding notice is in the interests of the Holders of the Notes. 

SECTION 502. Acceleration of Maturity; Rescission and Annulment. 

If an Event of Default (other than by reason of an Event of Default specified in clause (vi) or (vii) of the first paragraph of
Section 501) occurs and is continuing, the Trustee or the Holders of not less than 25% in principal amount of the Notes then outstanding may declare the principal and accrued and unpaid interest on all the Notes to be due and payable
immediately, by a notice in writing to the Issuers (and to the Trustee if given by Holders). Upon the effectiveness of such declaration, such principal will be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of
Default specified in clause (vi) or (vii) of the first paragraph of Section 501 occurs and is continuing, then the principal amount of all the Notes shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder. 
 The Holders of a majority in principal amount of the Notes then
outstanding by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived (except nonpayment of principal,
interest and premium, if any, that has become due solely because of acceleration). The Trustee may rely upon such notice of rescission without any independent investigation as to the satisfaction of the conditions in the preceding sentence. No such
rescission shall affect any subsequent Default or impair any right consequent thereto. 
 SECTION 503. Collection of Indebtedness and
Suits for Enforcement by Trustee. 
 If an Event of Default specified in clause (i) or (ii) of the first paragraph of
Section 501 occurs and is continuing, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree
and may enforce the same against the Issuers or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Issuers or any other obligor upon the Notes, wherever
situated. 

  
 -59- 








 If an Event of Default occurs and is continuing the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders under this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy, subject however to Section 513. No recovery of any such judgment upon any property of the Issuers shall affect
or impair any rights, powers or remedies of the Trustee or the Holders. 
 SECTION 504. Trustee May File Proofs of Claim. 

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Issuers or any other obligor, upon the Notes or the property of the Issuers or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Issuers for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by
intervention in such proceeding or otherwise, 
 (i) to file and prove a claim for the whole amount of principal (and
premium, if any), interest and Additional Interest, if any, owing and unpaid in respect of the Notes, to take such other actions (including participating as a member, voting or otherwise, of any official committee of creditors appointed in such
matter) and to file such other papers or documents and take such other actions as the Trustee (including, participation as a member of any creditors committee) may deem necessary or advisable in order to have the claims of the Trustee (including any

(ii) the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default, or (iii) if the Default that is the basis for such Event of Default has been cured.

in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of
an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder or group of Holders, holding in the aggregate more than
10% in principal amount of the outstanding Notes, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or interest or Additional Interest, if any, on any Note on or after the respective Stated Maturities

of a majority in principal amount of the outstanding Notes delivered to the Issuers and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the
successor Trustee appointed by the Issuers. If no successor Trustee shall have been so appointed by the Issuers or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Note for at
least six months may, at the expense of the Issuers on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

duties of the retiring Trustee; but, on request of the Issuers or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Notwithstanding the replacement of the Trustee pursuant to this Section 610,
the Issuers’ obligations under Section 607 shall continue for the benefit of the retiring Trustee with regard to expenses and liabilities incurred by it and compensation earned by it prior to such replacement or otherwise under this
Indenture. Upon request of any such successor Trustee, the Issuers shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts.

merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided
such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had
itself authenticated such Notes. In case at that time any of the Notes shall not have been authenticated, any successor Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee. In
all such cases such certificates shall have the full force and effect which this Indenture provides for the certificate of authentication of the Trustee shall have; provided, however, that the right to adopt the certificate of
authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Any application by the Trustee for written instructions from the Issuers may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. Subject to Section 610, the Trustee shall not be liable for any action taken
by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any officer of the Issuers actually
receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions

in connection with a tender offer or exchange offer for the Notes), the Issuers, the Guarantors and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each
outstanding Note affected thereby (with respect to any Notes held by a nonconsenting Holder of the Notes): 
 (i) change or
extend the fixed maturity of any Notes, reduce the rate or extend the time of payment of interest or Additional Interest thereon, reduce the principal amount thereof or premium, if any, thereon or change the currency in which the Notes are payable;

Additional Interest on the Notes, may be waived with the consent of Holders of at least a majority in aggregate principal amount of the Notes at the time outstanding. The consent of the Holders is not necessary under this Indenture to approve the
particular form of any proposed amendment or supplemental indenture. It is sufficient if such consent approves the substance of the proposed amendment or supplemental indenture. 

SECTION 903. Execution of Supplemental Indentures. 

The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee’s own rights, duties
or immunities, as determined by the Trustee in its sole discretion under this Indenture or otherwise. In signing or refusing to sign any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this
Indenture. 
 SECTION 904. Effect of Supplemental Indentures. 

Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such

Issuers, and the Issuers shall issue and the Trustee shall authenticate a new Note that reflects the changed terms, the cost and expense of which will be borne by the Issuers in exchange for outstanding Notes.

 SECTION 907. Notice of Supplemental Indentures. 

Promptly after the execution by the Issuers and the Trustee of any supplemental indenture pursuant to the provisions of Section 902, the
Issuers shall give notice thereof to the Holders of each outstanding Note affected, in the manner provided for in Section 106, setting forth in general terms the substance of such supplemental indenture. The failure to give such notice to all
the Holders, or any defect therein, will not impair or affect the validity of the supplemental indenture. 
 SECTION 908. Treasury
Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver, consent
or notice, Notes owned by any Issuer or any of its Affiliates shall be considered as though they are not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or
consent, only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so considered. Each Issuer shall notify the Trustee, in writing, when it or any of its Affiliates repurchases or otherwise acquires Notes and of the
aggregate principal amount of such Notes so repurchased or otherwise acquired. 
 ARTICLE TEN 

COVENANTS  
 SECTION
1001. Payment of Principal, Premium, if Any, and Interest. 
 The Issuers, as joint and several obligors, covenant and agree for the
benefit of the Holders that they will duly and punctually pay the principal of (and premium, if any) and interest and Additional Interest, if any, on the Notes in accordance with the terms of the Notes and this Indenture. 

SECTION 1002. Maintenance of Office or Agency. 

The Issuers will maintain in the Borough of Manhattan, The City of New York, an office or agency where the Notes may be presented or
surrendered for payment, where, if applicable, the Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Issuers in respect of the Notes and this Indenture may be served. The principal
corporate trust office of the Trustee at 400 Madison Avenue, 4th Floor, New York, New York 10017, shall be such office or agency of the Issuers, unless the Issuers shall designate and maintain
some other office or agency for one or more of such purposes. The Issuers will give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Issuers shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office, and the Issuers hereby appoint the Trustee as their agent to
receive all such presentations, surrenders, notices and demands. 
 The Issuers may also from time to time designate one or more other
offices or agencies (in or outside of The City of New York) where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind any such designation; provided, however, that no such
designation or rescission shall in any manner relieve any Issuer of its obligation to maintain an office or agency in The City of New York for such purposes. The Issuers will give prompt written notice to the Trustee of any such designation or
rescission and any change in the location of any such other office or agency. 

  
 -75- 








 SECTION 1003. Money for Note Payments to Be Held in Trust. 

If the Issuers shall at any time act as their own Paying Agent, they will, on or before each due date of the principal of (or premium, if any)
or interest on any of the Notes, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal of (or premium, if any) or interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and will promptly notify the Trustee of their action or failure to so act. 
 Whenever the Issuers
shall have one or more Paying Agents for the Notes, they will, on or before each due date of the principal of (or premium, if any) or interest on any Notes, deposit with a Paying Agent a sum in same day funds (or New York Clearing House funds if
such deposit is made prior to the date on which such deposit is required to be made) that shall be available to the Trustee by 10:00 a.m. Eastern Standard Time on such due date sufficient to pay the principal (and premium, if any) or interest (and
Additional Interest, if any) so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Issuers will promptly notify the Trustee of
such action or any failure to so act. 
 The Issuers will cause each Paying Agent (other than the Trustee) to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: 

(i) hold all sums held by it for the payment of the principal of (and premium, if any) or interest (and Additional Interest, if
any) on Notes in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 

(ii) give the Trustee notice of any default by the Issuers (or any other obligor upon the Notes) in the making of any payment
of principal (and premium, if any) or interest (and Additional Interest, if any); and 
 (iii) at any time during the
continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 

The Issuers may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or
direct (pursuant to a written direction signed by two Officers of each Issuer) any Paying Agent to pay, to the Trustee all sums held in trust by the Issuers or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon
which such sums were held by the Issuers or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums. 

Any money deposited with the Trustee or any Paying Agent, or by the Issuers, in trust for the payment of the principal of (or premium, if any)
or interest (or Additional Interest, if any) on any Note and remaining unclaimed for two years after such principal, premium, interest or Additional Interest has become due and payable shall be paid to the Issuers on the Issuers’ Request, or
(if then held by the Issuers) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent
with respect to such trust money, and all liability of the Issuers as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment to the Issuers,
may at the expense of the Issuers cause to be published once, in a leading daily newspaper (if practicable, The Wall Street Journal (Eastern Edition)) printed in the English language and of general circulation in New York City, notice that
such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Issuers.

 SECTION 1004. Corporate Existence. 

Subject to Article Eight, the Issuers will do or cause to be done all things necessary to preserve and keep in full force and effect their
limited liability company or corporate existence, as the case may be, and that of each Restricted Subsidiary and the limited liability company or corporate rights, as the case may be (charter and statutory), licenses and franchises of the Issuers
and each Restricted Subsidiary; provided, however, that the Issuers shall not be required to preserve any such existence (except the Issuers) right, license or franchise if the Executive Committee of Mediacom Broadband LLC shall
determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuers and each of Mediacom Broadband LLC’s Restricted Subsidiaries, taken as a whole, and that the loss thereof is not, and will not be,
disadvantageous in any material respect to the Holders. 
 SECTION 1005. Payment of Taxes and Other Claims. 

The Issuers will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (i) all material taxes,
assessments and governmental charges levied or imposed upon the Issuers or any Subsidiary or upon the income, profits or property of the Issuers or any Subsidiary and (ii) all lawful claims for labor, materials and supplies, which, if unpaid,
might by law become a material liability or lien upon the property of the Issuers or any Restricted Subsidiary; provided, however, that the Issuers shall not be required to pay or discharge or cause to be paid or discharged any such
tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings and for which appropriate reserves, if necessary (in the good faith judgment of management of the Issuers) are being
maintained in accordance with GAAP. 
 SECTION 1006. Compliance with Laws. 

The Issuers shall comply, and shall cause each of their respective Restricted Subsidiaries to comply, with all applicable statutes, rules,
regulations, orders and restrictions of the United States of America, all states and municipalities thereof, and of any governmental regulatory authority, in respect of the conduct of their respective businesses and the ownership of their respective
properties, except for such non-compliances as would not in the aggregate have a material adverse effect on the financial condition or results of operations of the Issuers and their respective Restricted Subsidiaries, taken as a whole. 

SECTION 1007. Limitation on Restricted Payments. 

(a) So long as any of the Notes remain outstanding, Mediacom Broadband LLC shall not, and shall not permit any Restricted Subsidiary to, make
any Restricted Payment if: (i) at the time of such proposed Restricted Payment, a Default or Event of Default shall have occurred and be continuing or shall occur as a consequence of such Restricted Payment; (ii) immediately after giving
effect to such proposed Restricted Payment, Mediacom Broadband LLC would not be able to Incur $1.00 of additional Indebtedness under the Debt to Operating Cash Flow Ratio of the first paragraph of Section 1008, or (iii) immediately after

market value thereof on the date of such Restricted Payment (without giving effect to subsequent changes in value) as determined in good faith by the Executive Committee, whose determination shall be conclusive and evidenced by a Committee
Resolution) would exceed an amount equal to the difference between (a) the Cumulative Credit and (b) 1.2 times Cumulative Interest Expense.

 Broadband LLC or any of its Restricted Subsidiaries, on the one hand, and Mediacom Communications or any of its

Notwithstanding the foregoing, any transaction (or series of related transactions) entered into by Mediacom Broadband LLC or any Restricted Subsidiary with any Affiliate without complying with the foregoing provisions of this Section 1009 shall
not constitute a violation of the provisions of this Section 1009 if Mediacom Broadband LLC or such Restricted Subsidiary would be permitted to make a Restricted Payment pursuant to paragraph (a) of Section 1007 at the time of the
completion of such transaction (or series of related transactions) in an amount equal to the fair market value of such transaction (or series of related transactions), as determined in good faith by the Executive Committee, whose determination shall

provisions of this Section 1010, (vi) existing agreements as in effect on the date of this Indenture and as amended, modified, extended, renewed, refunded, refinanced, restated or replaced from time to time, provided that any such
agreement as so amended, modified, extended, renewed, refunded, refinanced, restated or replaced is not materially more restrictive, taken as a whole, as to the Specified Actions than such agreement as in effect on the date of this Indenture;

equitable to Holders. Upon completion of the Excess Proceeds Offer, the amount of Excess Proceeds shall be reset to zero.

formed Subsidiary or a Person becoming a Subsidiary through merger or consolidation or Investment therein) as an “Unrestricted Subsidiary” under this Indenture (a “Designation”) only if: (a) no Default or Event of Default
shall have occurred and be continuing at the time of or after giving effect to such Designation; (b) at the time of and after giving effect to such Designation, Mediacom Broadband LLC would be able to Incur $1.00 of additional Indebtedness
under the Debt to Operating Cash Flow Ratio under the first paragraph of Section 1008; and (c) Mediacom Broadband LLC would be permitted to make a Restricted Payment at the time of Designation (assuming the effectiveness of such
Designation) pursuant to paragraph (a) of Section 1007 in an amount (the “Designation Amount”) equal to Mediacom Broadband LLC’s proportionate interest in the fair market value of such Subsidiary on such date (as determined
in good faith by the Executive Committee, whose determination shall be conclusive and evidenced by a Committee Resolution). Notwithstanding the foregoing, neither Mediacom Broadband Corporation nor any of its Subsidiaries may be designated as
Unrestricted Subsidiaries. 

  
 -89- 








 (b) At the time of Designation all of the Indebtedness of such Unrestricted Subsidiary shall
consist of, and shall at all times thereafter consist of, Non-Recourse Indebtedness, and neither Mediacom Broadband LLC nor any Restricted Subsidiary shall at any time have any direct or indirect obligation to: (x) make additional Investments

(z) be party to any agreement, contract, arrangement or understanding with any Unrestricted Subsidiary unless the terms of any such agreement, contract, arrangement or understanding are no less favorable to Mediacom Broadband LLC or such
Restricted Subsidiary than those that might be obtained, in light of all the circumstances, at the time from Persons who are not Affiliates of Mediacom Broadband LLC. If, at any time, any Unrestricted Subsidiary would violate the foregoing
requirements, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary shall be deemed to be Incurred as of such date.

Default or Event of Default shall have occurred and be continuing at the time of or after giving effect to such Revocation; (b) at the time of and after giving effect to such Revocation, Mediacom Broadband LLC would be able to Incur $1.00 of
additional Indebtedness under the Debt to Operating Cash Flow Ratio of the first paragraph of Section 1008; and (c) all Liens and Indebtedness of such Unrestricted Subsidiary outstanding immediately following such Revocation would, if
Incurred at such time, have been permitted to be Incurred for all purposes of this Indenture. 
 (d) All Designations and Revocations must be
evidenced by Committee Resolutions delivered to the Trustee certifying compliance with the foregoing provisions. 
 ARTICLE ELEVEN

 REDEMPTION OF NOTES 

SECTION 1101. Optional Redemption. 

The Notes may or shall, as the case may be, be redeemed, as a whole or from time to time in part, subject to the conditions and at the
redemption prices specified in the Form of Note (Section 203), together with accrued and unpaid interest and Additional Interest, if any, thereon to the date of redemption. 

SECTION 1102. Applicability of Article. 

Redemption of Notes at the election of the Issuers or otherwise, as permitted or required by any provision of this Indenture, shall be made in
accordance with such provision and this Article. 
 SECTION 1103. Election to Redeem; Notice to Trustee. 

The election of the Issuers to redeem any Notes pursuant to Section 1101 shall be evidenced by a Committee Resolution. In case of any
redemption at the election of the Issuers, the Issuers shall, at least 90 days prior to the date of redemption (the “Redemption Date”) fixed by the Issuers (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee
of such Redemption Date and of the principal amount of Notes to be redeemed and shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Notes to be redeemed pursuant to Section 1104. 

  
 -90- 








 SECTION 1104. Selection by Trustee of Notes to Be Redeemed. 

If fewer than all the Notes are to be redeemed, the Trustee will select the Notes to be redeemed, if the Notes are listed on a national
securities exchange, in accordance with the rules of such exchange or, if the Notes are not so listed, on a pro rata basis or by lot or by such other method that the Trustee deems to be fair and equitable to Holders; provided that, if a
partial redemption is made with the proceeds of any Equity Offering, selection of the Notes or portions thereof for redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable
(subject to the procedures of the Depositary). If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed and a new Note or Notes in principal
amount equal to the unredeemed principal portion thereof will be issued; provided, that no Notes of a principal amount of $2,000 or less shall be redeemed in part. On and after the Redemption Date, interest will cease to accrue on Notes or
portions thereof called for redemption as long as the Issuers have deposited with the Paying Agent for the Notes funds in satisfaction of the applicable redemption price pursuant to this Indenture. 

The Trustee shall promptly notify the Issuers in writing of the Notes selected for redemption and, in the case of any Notes selected for
partial redemption, the principal amount thereof to be redeemed. 
 For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to redemption of Notes shall relate, in the case of any Note redeemed or to be redeemed only in part, to the portion of the principal amount of such Note which has been or is to be redeemed. 

SECTION 1105. Notice of Redemption. 

Notice of redemption shall be given in the manner provided for in Section 106 not less than 30 nor more than 60 days’ prior to the
Redemption Date by first class mail to each Holder of Notes to be redeemed at such Holder’s address appearing in the Note Register. The Trustee shall give notice of redemption in the Issuers’ name and at the Issuers’ expense;
provided, however, that the Issuers shall deliver to the Trustee, at least 45 days prior to the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee), an Officers’ Certificate requesting that the Trustee
give such notice and setting forth the information to be stated in such notice as provided in the following items. 
 All notices of
redemption shall state: 
 (i) the Redemption Date, 

(ii) the redemption price and the amount of accrued interest to the Redemption Date payable as provided in Section 1107,
if any, 
 (iii) if less than all outstanding Notes are to be redeemed, the identification of the particular Notes (or
portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption, 

(iv) in case any Note is to be redeemed in part only, the notice which relates to such Note shall state that on and after the
Redemption Date, upon surrender of such Note, the Holder will receive, without charge, a new Note or Notes of authorized denominations for the principal amount thereof remaining unredeemed, 

(v) that on the Redemption Date the redemption price (and accrued interest, if any, to the Redemption Date payable as provided
in Section 1107) will become due and payable upon each such Note, or the portion thereof, to be redeemed, and, unless the Issuers defaults in making the redemption payment, that interest on Notes called for redemption (or the portion thereof)
will cease to accrue on and after said date, 

  
 -91- 








 (vi) the place or places where such Notes are to be surrendered for payment of
the redemption price and accrued interest, if any, 
 (vii) the name and address of the Paying Agent, 

(viii) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price, 

(ix) the CUSIP number, and that no representation is made as to the accuracy or correctness of the CUSIP number, if any, listed
in such notice or printed on the Notes, and 
 (x) the paragraph of the Notes or Section of this Indenture pursuant to which
the Notes are to be redeemed. 
 SECTION 1106. Deposit of Redemption Price. 

Prior to any Redemption Date, the Issuers shall deposit with the Paying Agent (or, if the Issuers are acting as their own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the redemption price of, and accrued interest on, all the Notes which are to be redeemed on that date. Promptly after the calculation of the
redemption price, the Issuers will give the Trustee and the Paying Agent notice thereof. 
 SECTION 1107. Notes Payable on Redemption
Date. 
 Notice of redemption having been given as aforesaid, the Notes so to be redeemed shall, on the Redemption Date, become due and
payable at the redemption price therein specified (together with accrued interest, if any, to the Redemption Date), and from and after such date (unless the Issuers shall default in the payment of the redemption price and accrued interest) such
Notes shall cease to bear interest. Upon surrender of any such Note for redemption in accordance with said notice, such Note shall be paid by the Issuers at the redemption price, together with accrued interest, if any, to the Redemption Date;
provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Notes, or one or more predecessor Notes, registered as such at the close of business on the
relevant Regular Record Date or Special Record Date, as the case may be, according to their terms and the provisions of Section 311. 

If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until
paid, bear interest from the Redemption Date at the rate borne by the Notes. 
 SECTION 1108. Notes Redeemed in Part. 

Any Note which is to be redeemed only in part (pursuant to the provisions of this Article) shall be surrendered at the office or agency of the
Issuers maintained for such purpose pursuant to Section 1002 (with, if the Issuers or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuers and the Trustee duly executed by, the
Holder thereof or such Holder’s attorney duly authorized in writing), and the Issuers shall execute, and the Trustee shall authenticate and deliver to the Holder of such Note at the expense of the Issuers, a new Note or Notes, of any authorized
denomination as requested by such Holder, in an aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered, provided, that each such new Note will be in a principal amount of
$2,000 or integral multiples of $1,000 in excess thereof.

 ARTICLE TWELVE 

DEFEASANCE AND COVENANT DEFEASANCE 

SECTION 1201. The Issuers’ Option to Effect Defeasance or Covenant Defeasance. 

The Issuers may, at their option, at any time, with respect to the Notes, elect to have either Section 1202 or Section 1203 be
applied to all outstanding Notes upon compliance with the conditions set forth in this Article Twelve. The Issuers in their sole discretion can defease the Notes. 

SECTION 1202. Legal Defeasance and Discharge. 

Upon the Issuers’ exercise under Section 1201 of the option applicable to this Section 1202, the Issuers shall be deemed to have
been discharged from any and all obligations with respect to all outstanding Notes on the date the conditions set forth in Section 1204 are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means
that the Issuers shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 1205 and the other
Sections of this Indenture referred to in (i) and (ii) below, and to have satisfied all its other obligations under such Notes and this Indenture insofar as such Notes are concerned (and the Trustee, at the expense of the Issuers, shall
execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of outstanding Notes to receive, solely from the trust fund described
in Section 1204 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any, on) and interest on such Notes when such payments are due, (ii) the Issuers’ obligations with respect to such
Notes under Sections 304, 305, 310, 1002 and 1003, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder, and the Issuers’ obligations in connection therewith and (iv) this Article Twelve. 

If the Issuers exercise their Legal Defeasance option, payment of the Notes may not be accelerated because of an Event of Default. 

Subject to compliance with this Article Twelve, the Issuers may exercise their option under this Section 1202 notwithstanding the prior
exercise of their option under Section 1203 with respect to the Notes. 
 SECTION 1203. Covenant Defeasance. 

Upon the Issuers’ exercise under Section 1201 of the option applicable to this Section 1203, the Issuers may terminate
(i) its obligations under any covenant contained in Sections 1007 through 1015 and Section 1017, (ii) the operation of Section 501(iv), Section 501(v), Section 501(vi) (with respect only to Significant Subsidiaries),
Section 501(vii) (with respect only to Significant Subsidiaries) and Section 501(iii) (with respect to the covenants described in clause (i) above) and (iii) the limitations contained in Sections 801(iii) and 801(iv)
(hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not to be “outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be outstanding for accounting purposes). If the Issuers exercise their covenant
defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified under Section 501(iv), (v), (vi) (with respect only to Significant Subsidiaries), (vii) (with respect only to Significant
Subsidiaries) and Section 501(viii) (with respect to the covenants described in clause (i) above) or because of the failure of the Issuers to comply with Section 801(iii) and 801(iv). For this purpose, such Covenant Defeasance means
that, with respect to the outstanding Notes, the Issuers may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under
Section 501(iii), but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. 

  
 -93- 








 SECTION 1204. Conditions to Legal Defeasance or Covenant Defeasance. 

The following shall be the conditions to application of either Section 1202 or Section 1203 to the outstanding Notes:

for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not
occurred;

Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;

or similar laws affecting creditors’ rights generally under any applicable U.S. federal or state law, and that the Trustee has a perfected security interest in such trust funds for the ratable benefit of the Holders and (B) such Legal
Defeasance or Covenant Defeasance, as the case may be, will not require registration of the Issuers, the Trustee or the trust fund under the Investment Company Act of 1940, as amended or the Investment Advisors Act of 1940, as amended; 

(vii) The Issuers shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by

 Subject to the provisions of the last paragraph of Section 1003, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1205, the “Trustee”) pursuant to Section 1204 in respect of the
outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuers acting as their own Paying

nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent defeasance
or covenant defeasance, as applicable, in accordance with this Article.

 ARTICLE THIRTEEN

 RESTRICTED SUBSIDIARY GUARANTEE 

SECTION 1301. Unconditional Guarantee. 

Each Guarantor hereby unconditionally, jointly and severally, guarantees to each Holder of a Note authenticated and delivered by the Trustee
and to the Trustee and its successors and assigns that: the principal of and interest and Additional Interest, if any, on the Notes shall be promptly paid in full when due, subject to any applicable grace period, whether at maturity, by acceleration
or otherwise, and interest and Additional Interest, if any, on the overdue principal, premium, if any, and interest on any overdue interest on the Notes and all other obligations of the Issuers to the Holders or the Trustee hereunder or under the
Notes shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; subject, however, to the limitations set forth in Section 1303. Each Guarantor hereby agrees that its obligations hereunder shall be
unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of the any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or
thereof, the recovery of any judgment against the Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenants that the
Restricted Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in the Notes, this Indenture, and this Restricted Subsidiary Guarantee. If any Holder or the Trustee is required by any court or
otherwise to return to the Issuers, any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuers or any Guarantor, any amount paid by the Issuers to any Guarantor to the Trustee or such Holder,
this Restricted Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other
hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Five for the purpose of this Restricted Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration in respect of such obligations as provided in Article Five, such obligations (whether or not due and payable) shall forthwith become due and
payable by each Guarantor for the purpose of this Restricted Subsidiary Guarantee. 
 SECTION 1302. Severability. 

In case any provision of this Article Twelve and the Restricted Subsidiary Guarantee shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

  
 -96- 








 SECTION 1303. Limitation of Guarantor’s Liability. 

Each Guarantor, and by its acceptance hereof each Holder and the Trustee, hereby confirms that it is the intention of all such parties that the
guarantee by such Guarantor pursuant to its Restricted Subsidiary Guarantee not constitute a fraudulent transfer or conveyance for purposes of title 11 of the United States Code, as amended, the Uniform Fraudulent Conveyance Act, the Uniform
Fraudulent Transfer Act or any similar U.S. Federal or state or other applicable law or that the obligations of such Guarantor under Section 1301 would otherwise be held or determined to be void, invalid or unenforceable on account of the
amount of its liability under said Section 1301. To effectuate the foregoing intention, the Holders and such Guarantor hereby irrevocably agree that the obligations of such Guarantor under the Restricted Subsidiary Guarantee shall be limited to
the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of
such other Guarantor under its Restricted Subsidiary Guarantee or pursuant to Section 1304, result in the obligations of such Guarantor under the Restricted Subsidiary Guarantee not constituting such fraudulent transfer or conveyance and not
being held or determined to be void, invalid or unenforceable. 
 SECTION 1304. Contribution. 

In order to provide for just and equitable contribution among the Guarantors, the Guarantors agree, inter se, that in the event any payment or
distribution is made by any Guarantor (a “Funding Guarantor”) under the Restricted Subsidiary Guarantee, such Funding Guarantor shall be entitled to a contribution from all other Guarantors in a pro rata amount, based on the net assets of
each Guarantor (including the Funding Guarantor), determined in accordance with GAAP, subject to Section 1303, for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Issuers’ obligations with respect
to the Notes or any other Guarantor’s obligations with respect to the Restricted Subsidiary Guarantee. 
 SECTION 1305. Additional
Guarantors. 
 Any Restricted Subsidiary which is required pursuant to Section 1017 to become a Guarantor shall (a) execute and
deliver to the Trustee a supplemental indenture in form and substance reasonably satisfactory to the Trustee which subjects such Restricted Subsidiary to the provisions of this Indenture as a Guarantor and pursuant to which such Restricted
Subsidiary agrees to guarantee to each Holder of a Note the payment of amounts due in respect of the Notes in accordance with the provisions of this Indenture, and (b) cause to be delivered to the Trustee an Opinion of Counsel to the effect
that such supplemental indenture has been duly authorized and executed by such Restricted Subsidiary and constitutes the legal, valid, binding and enforceable obligation of such Restricted Subsidiary (subject to such customary exceptions concerning
fraudulent conveyance laws, creditors’ rights and equitable principles). 
 SECTION 1306. Subordination of Subrogation and Other
Rights. 
 Each Guarantor hereby agrees that any claim against the Issuers that arises from the payment, performance or enforcement of
such Guarantor’s obligations under its Restricted Subsidiary Guarantee or this Indenture, including, without limitation, any right of subrogation, shall be subject and subordinate to, and no payment with respect to any such claim of such
Guarantor shall be made before, the payment in full in cash of all outstanding Notes in accordance with the provisions provided therefor in this Indenture.
