 (iv) If the Issuers shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Issuers may, at their option, by or pursuant to a Committee
Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Issuers shall have no obligation to do so. Notwithstanding TIA
§ 316(c), such record date shall be the record date specified in or pursuant to such Committee Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and
not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of
record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date
shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. 
 (v) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof (including in accordance with Section 310) in respect of anything done, omitted or suffered to be done by the Trustee, any Paying Agent or the Issuers in reliance
thereon, whether or not notation of such action is made upon such Note.

 SECTION 105. Notices, Etc., to Trustee and the Issuers. 

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with, 
 (1) the Trustee by any Holder or by the
Issuers or any other obligor on the Notes shall be sufficient for every purpose hereunder if in writing and delivered in person, mailed by first class mail (registered or certified, return receipt requested) or overnight air courier guaranteeing
next day delivery, or transmitted by facsimile, to the Trustee and received at its Corporate Trust Office, Attention: Corporate Trust Administration (facsimile number (212)-750-1361). Any such request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document given to the Trustee shall be sent in duplicate to the Paying Agent if the Paying Agent is not the Trustee, or 

(2) the Issuers by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein
expressly provided) if in writing and delivered in person, mailed by first class mail (registered or certified, return receipt requested) or overnight air courier guaranteeing next day delivery, or transmitted by facsimile, to the Issuers addressed
to them and received at the address of their principal office specified in the first paragraph of this Indenture (or, in the case of facsimile, at facsimile number (845) 695-2669), Attention: General Counsel, or at any other address (or
facsimile number) previously furnished in writing to the Trustee by the Issuers. 
 In the event any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other document is transmitted by facsimile as provided in the foregoing paragraph, the sender shall promptly deliver to the recipient, at the recipient’s address specified
above, an original copy of such request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document; provided that the failure to so deliver such original copy shall not affect the sufficiency of the
facsimile transmittal. 
 SECTION 106. Notice to Holders; Waiver. 

Where this Indenture provides for notice of any event to Holders by the Issuers or the Trustee, such notice shall be sufficiently given
(unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder, at his address as it appears in the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed
for the giving of such notice. Neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Any notice mailed to a Holder in the
manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such waiver. 
 In case by reason of the suspension of or irregularities in
regular mail service or by reason of any other cause, it shall be impracticable to mail notice of any event to Holders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as
shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice for every purpose hereunder. 

  
 -22-

 If the Issuers mail any notice or communication to any Holder, they shall mail a copy to the
Trustee at the same time. 
 SECTION 107. Effect of Headings and Table of Contents. 

The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

 SECTION 108. Successors and Assigns. 
 All covenants and agreements in this Indenture by the Issuers shall bind each of their successors and assigns, whether so expressed or not. 

SECTION 109. Separability Clause. 
 In case any provision in this Indenture or in the Notes 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. 
 SECTION 110. Benefits of Indenture. 

Nothing in this Indenture or in the Notes, express or implied, shall give to any Person (other than the parties hereto, any agent and
their successors hereunder and each of the Holders) any benefit or any legal or equitable right, remedy or claim under this Indenture. 
 SECTION 111. Governing Law. 
 THIS INDENTURE AND THE NOTES SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK EXCLUDING (TO THE GREATEST EXTENT PERMISSIBLE BY LAW) ANY RULE OF LAW THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF NEW YORK.

APPLICABLE, BE GOVERNED BY SUCH PROVISIONS. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE U.S. FEDERAL COURTS, IN EACH CASE SITTING IN THE BOROUGH OF MANHATTAN, AND WAIVES ANY
OBJECTION AS TO VENUE OR FORUM NON CONVENIENS. 
 SECTION 112. Legal Holidays. 

In any case where any interest payment date, any date established for payment of Defaulted Interest pursuant to Section 311 or
Redemption Date or Stated Maturity of any Note shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Notes) payment of principal (or premium, if any) or interest need not be made on such date, but may be
made on the next succeeding Business Day with the same force and effect as if made on the interest payment date or date established for payment of Defaulted Interest pursuant to Section 311, Redemption Date, or at the Stated Maturity or
maturity; provided that no interest shall accrue on the payment so deferred for the period from and after such interest payment date, Redemption Date or date established for payment of Defaulted Interest pursuant to Section 311, Stated
Maturity or maturity, as the case may be, to the next succeeding Business Day.

 SECTION 113. No Personal Liability of Directors, Officers, Employees, Stockholders or
Incorporators. 
 No manager, director, officer, employee, member, shareholder, partner or incorporator of either Issuer or
any Subsidiary, as such, shall have any liability for any obligations of the Issuers under the Notes, this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note
waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of the Notes. 

SECTION 114. Counterparts. 
 This Indenture may be signed in any number of counterparts each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same Indenture.

purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes. 
 SECTION 115. Communications by Holders with Other Holders.

The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot Act, the Trustee, like all financial
institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account with the
Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the U.S.A. Patriot Act.

 [FORM OF REVERSE SIDE OF SENIOR NOTE] 

6 
3/8% Senior Notes due 2023 

 

	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 6 3/8% Senior Notes due 2023 (the “Notes”) will accrue at a rate of 6 3/8% per annum, payable semiannually, to Holders of record on each March 15 and September 15 immediately preceding the interest payment date on April 1 and October 1 of each year
during which any portion of the Notes shall be outstanding (each an “Interest Payment Date”), commencing April 1, 2013. 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 August 28, 2012 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 August 28, 2012 (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 $300,000,000, 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.

	6.	Optional Redemption

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 1 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:

 Notwithstanding the foregoing, at any time prior to April 1, 2018, 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 October 1, 2015,
the Issuers may redeem up to 35% 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
106.375% 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 65% 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 

  
 -35-

 
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. 
  

	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. 

  
 -36-

	15.	Trustee Dealings with the Issuers 

 Subject to certain limitations set forth in the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with
and collect obligations owed to it by the Issuers or their affiliates and may otherwise deal with the Issuers or their affiliates with the same rights it would have if it were not Trustee. 

 

	16.	No Recourse Against Others 

A manager, director, officer, employee, member, shareholder, partner or incorporator of either Issuer or any Subsidiary, as such, shall
not have any liability for any obligations of the Issuers under the Notes or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. By accepting a Note, each Noteholder waives and releases all
such liability.

U/G/M/A (=Uniform Gift to Minors Act). 
  

	19.	CUSIP Numbers 

 Pursuant
to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuers have caused CUSIP numbers to be printed on the Notes and have directed the Trustee to use CUSIP numbers in notices of redemption as a
convenience to Holders of the Notes. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed
thereon.

 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 $300,000,000 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. 
 The
Initial Notes and the Additional Notes shall be known and designated as the “6 3/8% Senior Notes due 2023,” and the Exchange Notes shall be known and designated as the “6 3/8% Senior Notes due 2023,” in each case, of the Issuers. Interest on the Notes will accrue at a rate per annum of
6 3/8% and will be payable semiannually in cash and in arrears to the Holders of record on each March 15 and September 15

  
 -43-

 
immediately preceding the interest payment date on April 1 and October 1 of each year during which any portion of the Notes shall be outstanding (each, an “Interest Payment
Date”), commencing April 1, 2013. 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 August 28, 2012. 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

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.

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

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.

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.

 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.

 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.

 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.

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

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:

Mediacom Broadband LLC which, if merged into each other, would constitute a Significant Subsidiary, in an involuntary case;

 -58-

 (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. 
 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 

  
 -59-

 
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 claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the
Holders allowed in such judicial proceeding, and 
 (ii) to collect and receive any moneys or other property
payable or deliverable on any such claims and to distribute the same; 
 and any custodian in any such judicial proceeding is hereby authorized
by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of such Holders, vote for the
election of a trustee in bankruptcy or other similar official. 
 SECTION 505. Trustee May Enforce Claims Without Possession
of Notes. 
 All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee
without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes in respect of which such judgment has
been recovered. 

  
 -60-

 SECTION 506. Application of Money Collected. 

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

 FIRST: To the payment of all amounts due the Trustee under Section 607; 

SECOND: To the payment of the amounts then due and unpaid for principal of (and premium and Additional Interest, if any)

Additional Interest, if any), and interest, respectively; and 
 THIRD: The balance, if any, to the Person or
Persons entitled thereto, including the Issuers or any other obligor on the Notes, as their interests may appear or as a court of competent jurisdiction may direct, provided that all sums due and owing to the Holders and the Trustee have been
paid in full as required by this Indenture. 
 SECTION 507. Limitation on Suits. 

Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no Holder may pursue any remedy with
respect to this Indenture or the Notes unless: 
 (i) such Holder has previously given the Trustee notice that an
Event of Default is continuing; 
 (ii) Holders of at least 25% in principal amount of the outstanding Notes have
requested the Trustee to pursue the remedy; 
 (iii) such Holders have offered the Trustee security or indemnity
satisfactory to it against any loss, liability or expense; 
 (iv) the Trustee has not complied with such request
within 60 days after the receipt of the request and the offer of security or indemnity; and 
 (v) the Holders of
a majority in principal amount of the outstanding Notes have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period. 

it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture or any Note to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture or any Note, except in the
manner herein provided and for the equal and ratable benefit of all the Holders. 

  
 -61-

 SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and
Interest. 
 Notwithstanding any other provision in this Indenture the Holder of any Note shall have the right, which is
absolute and unconditional, to receive payment, as provided herein (including, if applicable, Article Eleven) and in such Note of the principal of (and premium, if any) and (subject to Section 311) interest and Additional Interest, if any, on
such Note on the respective Stated Maturities expressed in such Note (or, in the case of redemption or repurchase, on the applicable Redemption Date or applicable repurchase date) and to institute suit for the enforcement of any such payment, and
such rights shall not be impaired without the consent of such Holder. 
 SECTION 509. Restoration of Rights and Remedies.

 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Issuers, any other obligor on the
Notes, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been
instituted. 
 SECTION 510. Rights and Remedies Cumulative. 

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last
paragraph of Section 310, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy. 
 SECTION 511. Delay or Omission Not Waiver.

 No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
 SECTION 512. Control by Holders.

 Subject to Section 908, the Holders of a majority in principal amount of the outstanding Notes are given the right to
direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee, provided that 

(i) such direction shall not be in conflict with any rule of law or this Indenture; 

(ii) the Trustee need not take any action which might be unduly prejudicial to the rights of any other Holder or would
involve the Trustee in personal liability; and 
 (iii) subject to the provisions of TIA § 315, the Trustee
may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 

  
 -62-

 Prior to taking any action under this Indenture, the Trustee shall be entitled to
indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 
 SECTION 513. Waiver of Past Defaults. 
 Subject to Sections 508 and 902, the
Holders of a majority in aggregate principal amount of the outstanding Notes (including consents obtained in connection with a tender offer or exchange offer for the Notes) may on behalf of the Holders of all the Notes, by written notice to the
Trustee, waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of interest or Additional Interest, if any, on or the principal of, any such Note held
by a non-consenting Holder, or in respect of a covenant or a provision which cannot be amended or modified without the consent of the Holders of each outstanding Note affected thereby. 

In the event that any Event of Default specified in clause (iv) of the first paragraph of Section 501 shall have occurred and
be continuing, such Event of Default and all consequences thereof (including without limitation any acceleration or resulting payment default) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the
Holders of the Notes, if within 30 days after such Event of Default arose (i) the Indebtedness that is the basis for such Event of Default has been discharged, or (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. 
 Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend
to any subsequent or other Default or Event of Default or impair any right consequent thereon. 
 SECTION 514. Undertaking
for Costs. 
 All parties to this Indenture agree, and each Holder of any Note by his acceptance thereof shall be deemed to
have agreed, that any court may 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 expressed in such Note (or, in the case of redemption, on or after the applicable Redemption Date).

such corporation or its parent holding company publishes reports of condition at least annually, pursuant to law or to the requirements of federal, state, territorial or District of Columbia supervising or examining authority, then for the purposes
of this Section 608, the combined capital and surplus of such corporation or its parent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall
cease to be eligible in accordance with the provisions of this Section 608, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 

SECTION 609. Resignation and Removal; Appointment of Successor. 

(a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective
until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of this Section. 

(b) The Trustee may resign at any time by giving written notice thereof to the Issuers. Upon receiving such notice of resignation, the
Issuers shall promptly appoint a successor trustee by written instrument executed by authority of the Executive Committee, a copy of which shall be delivered to the resigning Trustee and a copy to the successor trustee. If an instrument of
acceptance required by this Section shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition, at the expense of the Issuers, any court of competent jurisdiction
for the appointment of a successor Trustee. 
 (c) The Trustee may be removed at any time by Act of the Holders of not less than
a majority in principal amount of the outstanding Notes, delivered to the Trustee and to the Issuers. The Trustee so removed may, at the expense of the Issuers, petition any court of competent jurisdiction for the appointment of a successor Trustee
if no successor Trustee is appointed within 30 days of such removal. 
 (d) If at any time: 

(i) the Trustee shall fail to comply with the provisions of TIA § 310(b) after written request therefor by the
Issuers or by any Holder who has been a bona fide Holder of a Note for at least six months, or 
 (ii) the
Trustee shall cease to be eligible under Section 608 and shall fail to resign after written request therefor by the Issuers or by any Holder who has been a bona fide Holder of a Note for at least six months, or 

(iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a custodian of the
Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 

then, in any such case, (A) the Issuers, by a Committee Resolution, may remove the Trustee, or (B) subject to TIA § 315(e), any Holder who has
been a bona fide Holder of a Note for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

  
 -68-

 (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, the Issuers, by a Committee Resolution, shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee shall be appointed by Act of the Holders 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. 
 (f) The Issuers shall give notice of each resignation and each removal of the Trustee and each appointment of a
successor Trustee to the Holders of Notes in the manner provided for in Section 106. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. 

SECTION 610. Acceptance of Appointment by Successor. 
 Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Issuers and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or
removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and 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. 
 No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. 

SECTION 611. Merger, Conversion, Consolidation or Succession to Business. 

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from
any 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 

  
 -69-

 
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. 
 SECTION 612.
Trustee’s Application for Instructions from the Issuers. 
 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 response to such application specifying the action to be taken or omitted.

of the then outstanding Notes (including consents obtained 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):

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 supplemental indenture shall form a part of this Indenture for all

SECTION 906. Reference in Notes to Supplemental Indentures. 

Notes authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may bear a notation in form

 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. 

  
 -74-

 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. 
 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 

  
 -75-

 
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) 

  
 -76-

 
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 giving effect to any such Restricted Payment, the aggregate of all Restricted Payments which shall have been made on or after
the Existing Notes Build-Up Date (the amount of any Restricted Payment, if other than cash, to be based upon the fair 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. 
 (b) The provisions of paragraph (a) of this Section 1007 shall not prevent any of the following, each of
which shall be given independent effect: (1) the retirement of any of Mediacom Broadband LLC’s Equity Interests in exchange for, or out of the proceeds of, the substantially concurrent sale (other than to a Subsidiary of Mediacom Broadband
LLC or an employee stock ownership plan or to a trust established by Mediacom Broadband LLC or any Subsidiary of Mediacom Broadband LLC for the benefit of its employees) of Equity Interests (other than Equity Interests issued in connection with the
AT&T Acquisitions Contributions) in Mediacom Broadband LLC; (2) the payment of any dividend or distribution on, or the redemption of, Equity Interests within 60 days after the date of declaration of such dividend or

  
 -77-

 
distribution or the giving of formal notice of such redemption, if at the date of such declaration or giving of such formal notice such payment or redemption would comply with the provisions of
this Indenture; (3) Investments constituting Restricted Payments made as a result of the receipt of non-cash consideration from any Asset Sale made pursuant to and in compliance with the provisions described under Section 1013;
(4) payments of compensation to officers, directors and employees of Mediacom Broadband LLC or any Restricted Subsidiary so long as the Executive Committee or the manager of Mediacom Broadband LLC in good faith shall have approved the terms
thereof; (5)(a) the payment of dividends on any Equity Interests in Mediacom Broadband LLC following the issuance thereof in an amount per annum of up to 6% of the net proceeds received by Mediacom Broadband LLC from an Equity Offering of such
Equity Interests and (b) the payment of cash dividends on the amount of the Mediacom Broadband Preferred Membership Interest at a rate not to exceed 6% per annum; (6)(a) the payment of management fees, and any related reimbursement of

 Mediacom Broadband LLC
shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, engage in any transaction (or series of related transactions) involving in the aggregate $5,000,000 or more with any Affiliate unless such transaction (or series
of related transactions) shall have been approved pursuant to a Committee Resolution rendered in good faith by the Executive Committee or, if applicable, a committee comprising the disinterested members of the Executive Committee, which approval in
each case shall be conclusive, to the effect that such transaction (or series of related transactions) is (a) in the best interest of Mediacom Broadband LLC or such Restricted Subsidiary and (b) upon terms which would be obtainable by
Mediacom Broadband LLC or such Restricted Subsidiary in a comparable arm’s-length transaction with a Person which is not an Affiliate, except that the foregoing shall not apply in the case of any of the following transactions (the

(iii) the payment of compensation (including, without limitation, amounts paid pursuant to employee benefit plans) for the personal services of, and indemnity provided on behalf of, officers, members, directors and employees of Mediacom

services theretofore or thereafter to be performed for such compensation or fees to be fair consideration therefor; (iv) any payments for goods or services purchased in the ordinary course of business, upon terms which would be obtainable by
Mediacom Broadband LLC or a Restricted Subsidiary in a comparable arm’s-length transaction with a Person which is not an Affiliate; (v) any transaction pursuant to any agreement with any Affiliate in effect on the date of this Indenture
(including, but not limited to, the Management Agreements, the Operating Agreement and other agreements relating to the payment of management fees, acquisition fees and expense reimbursements), including, without limitation, any amendments thereto
entered into after the date of this Indenture, provided that the terms of any such amendment are not less favorable to Mediacom Broadband LLC than the terms of the relevant agreement in effect prior to any such amendment, as determined in
good faith by the Executive Committee whose determination shall be conclusive and evidenced by a Committee Resolution; (vi) any transaction or series of transactions between Mediacom Broadband LLC or any of its Restricted Subsidiaries, on the
one hand, and Mediacom Communications or any of its direct or indirect Subsidiaries, on the other hand, which relate to (a) the sharing of centralized services, personnel, facilities, headends and plant, (b) the joint procurement of goods
and services, (c) the allocation of costs and expenses (other than taxes based on income) and (d) matters reasonably related to any of the foregoing, in each case, which are undertaken pursuant to an established plan of Mediacom

Subsidiaries involved in such transaction or series of transactions; provided that, in the case of this clause (vi), such plan shall have been approved pursuant to a Committee Resolution, rendered in good faith by the Executive Committee,

 -82-

 
Mediacom Communications and each such other Subsidiary of Mediacom Communications, on the other hand; and (vii) the receipt from any Affiliate of any payment, Investment, distribution, loan
or other extension of credit or any other consideration if the payment or making thereof would, if made by Mediacom Broadband LLC or by any Restricted Subsidiary to an Affiliate thereof, constitute a Specified Affiliate Transaction under any of the

Restricted Subsidiary to, directly or indirectly, engage in any transaction (or series of related transactions) involving in the aggregate (y) $25,000,000 or more in all instances except in the case of Asset Sales or Asset Swaps and (z) $50,000,000

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 be conclusive and
evidenced by a Committee Resolution. In such a case, Mediacom Broadband LLC or such Restricted Subsidiary, as the case may be, shall be deemed to have made a Restricted Payment in an amount equal to the fair market value of such transaction for
purposes of the calculation of Restricted Payments pursuant to clause (iii) of paragraph (a) of Section 1007.

Mediacom Broadband LLC shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or

encumbrances or restrictions existing under or by reason of: (i) Acquired Indebtedness or any other agreement or instrument of any Restricted Subsidiary existing at the time such Person became a Restricted Subsidiary, provided that such
encumbrances or restrictions were not created in anticipation of such Person becoming a Restricted Subsidiary and are not applicable to Mediacom Broadband LLC or any other Restricted Subsidiary, (ii) refinancing Indebtedness permitted by clause
(g) of the second paragraph under Section 1008; provided that the terms and conditions of any such encumbrances or restrictions are not materially more restrictive, taken as a whole, than those under the

  
 -83-

 
Indebtedness being refinanced, (iii) customary provisions restricting the assignment of any contract or interest of Mediacom Broadband LLC or any Restricted Subsidiary, (iv) this
Indenture or any other indenture governing debt securities that are not materially more restrictive, taken as a whole, than those contained in this Indenture, (v) the Subsidiary Credit Facility and the Future Subsidiary Credit Facilities;

such Future Subsidiary Credit Facility (“Comparable Restriction Provisions”); and provided, further, that if Mediacom Broadband LLC shall conclude in its sole discretion based on then prevailing market conditions that it is
not in the best interest of Mediacom Broadband LLC and the Restricted Subsidiaries to comply with the foregoing proviso, the failure to include Comparable Restriction Provisions in the agreements relating to such Future Subsidiary Credit Facility
shall not constitute a violation of the 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; (vii) applicable law; (viii) Capitalized Lease Obligations, mortgage financings or purchase money obligations, in each case that impose restrictions on the property purchased or leased of the nature
described in clause (d) above; (ix) any agreement for the sale or other disposition of a Restricted Subsidiary that restricts distributions by that Restricted Subsidiary pending its sale or other disposition; (x) Liens securing
Indebtedness otherwise permitted to be incurred under the provisions of Section 1011 that limit the right of the debtor to dispose of the assets subject to such Liens; (xi) provisions limiting the disposition or distribution of assets or
property in joint venture agreements, asset sale agreements, stock sale agreements and other similar agreements entered into (I) in the ordinary course of business or (II) with the approval of the Executive Committee of Mediacom Broadband LLC,

therewith effective provision is made to secure the Notes equally and ratably with such secured Indebtedness. This restriction does not, however, apply to Indebtedness secured by: (i) Liens, if any, in effect on the date of this Indenture;
(ii) Liens in favor of governmental bodies to secure progress or advance payments; (iii) Liens on Equity Interests or other assets existing at the time of the acquisition thereof (including, without limitation, acquisition through merger

determining in clause (ii) above the percentage of cash consideration received by Mediacom Broadband LLC or any Restricted Subsidiary, the amount of any (x) liabilities (as shown on Mediacom Broadband LLC’s or such Restricted
Subsidiary’s most recent balance sheet) of Mediacom Broadband LLC or any Restricted Subsidiary that are actually assumed by the transferee in such Asset Sale and from which Mediacom Broadband LLC and the Restricted Subsidiaries are fully
released shall be deemed to be cash, and (y) securities, notes or other similar obligations received by Mediacom Broadband LLC or such Restricted Subsidiary from such transferee that are immediately converted (or are converted within 30 days of
the related Asset Sale) by Mediacom Broadband LLC or such Restricted Subsidiary into cash shall be deemed to be cash in an amount equal to the net cash proceeds realized upon such conversion. 

(b) If the Issuers are required to make an Excess Proceeds Offer within 30 days following the Reinvestment Date, the Issuers shall send
by first class mail, postage prepaid, to the Trustee at its Corporate Trust Office and to each Holder of the Notes, at the address appearing in the register of the Notes maintained by the Note Registrar, a notice stating, among other things:
(1) that such Holders have the right to require the Issuers to apply the Excess Proceeds to repurchase such Notes at a purchase price in cash equal to 100% of the principal amount thereof plus accrued and unpaid interest and Additional
Interest, if any, thereon to the date of purchase; (2) the purchase date, which shall be a Business Day no earlier 

  
 -86-

 
than 30 days nor later than 60 days from the date such notice is mailed; (3) the instructions, determined by the Issuers, that each Holder must follow in order to have such Notes
repurchased; and (4) the calculations used in determining the amount of Excess Proceeds to be applied to the repurchase of such Notes. If the aggregate principal amount of Notes surrendered by Holders thereof exceeds the amount of Excess
Proceeds, the Trustee shall select the Notes to be purchased on a pro rata basis or by lot or by such other method that the Trustee deems to be fair and equitable to Holders. Upon completion of the Excess Proceeds Offer, the amount of Excess
Proceeds shall be reset to zero. 
 (c) The Issuers shall comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section 1013. 
 (d) Notwithstanding the foregoing, Mediacom Broadband LLC or any Restricted Subsidiary shall be permitted to consummate an Asset Swap if (i) at the time of entering into the related Asset Swap
Agreement or immediately after giving effect to such Asset Swap no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof and (ii) such Asset Swap shall have been approved in good faith by the
Executive Committee, whose approval shall be conclusive and evidenced by a Committee Resolution, which states that such Asset Swap is fair to Mediacom Broadband LLC or such Restricted Subsidiary, as the case may be, from a financial point of view.

 SECTION 1014. Reports. 
 Commencing with the fiscal quarter of the Issuers ending on September 30, 2012, whether or not the Issuers are subject to Section 13(a) or 15(d) of the Exchange Act or any successor provision
thereto, the Issuers shall file with the SEC (if permitted by SEC practice and applicable law and regulations) so long as the Notes are outstanding the annual reports, quarterly reports and other periodic reports which the Issuers would have been
required to file with the SEC pursuant to Section 13(a) or 15(d) or any successor provision thereto if the Issuers were so subject on or prior to the respective dates (the “Required Filing Dates”) by which the Issuers would have been
required to file such documents if the Issuers were so subject. The Issuers shall also in any event within 15 days of each Required Filing Date (whether or not permitted or required to be filed with the SEC) file with the Trustee, copies of the
annual reports, quarterly reports and other documents described in the preceding sentence. In addition, for so long as any Notes remain outstanding and prior to the later of the consummation of the Exchange Offer and the effectiveness of the Shelf
Registration Statement, if required, the Issuers shall furnish to Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

 Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s
receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuers’ compliance with any of its covenants hereunder (as to which the Trustee is
entitled to conclusively rely exclusively on Officers’ Certificates). 
 SECTION 1015. Limitation on Business Activities
of Mediacom Broadband Corporation.

any material obligations, engage in any trade or business, or conduct any business activity, other than the issuance of Equity Interests to Mediacom Broadband LLC or any Wholly Owned Restricted Subsidiary, the Incurrence of Indebtedness as a
co-obligor or guarantor of Indebtedness Incurred by Mediacom Broadband 

  
 -87-

 
LLC, including the Notes and the Exchange Notes, if any, that is permitted to be Incurred by Mediacom Broadband LLC under Section 1008 (provided that the net proceeds of such Indebtedness
are retained by Mediacom Broadband LLC or loaned to or contributed as capital to one or more of the Restricted Subsidiaries other than Mediacom Broadband Corporation), and activities incidental thereto. Neither Mediacom Broadband LLC nor any
Restricted Subsidiary shall engage in any transactions with Mediacom Broadband Corporation in violation of the immediately preceding sentence. 
 SECTION 1016. Statement by Officers as to Default. 
 (a) The Issuers will
deliver to the Trustee, within 120 days after the end of each fiscal year, an Officers’ Certificate, signed by, at a minimum, the principal executive officer, principal financial officer or principal accounting officer of each Issuer, and
otherwise meeting the requirements of Section 314(a)(4) of the Trust Indenture Act, stating that a review of the activities of the Issuers and the Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of
the signing Officers with a view to determining whether they have kept, observed, performed and fulfilled, and have caused each of the Restricted Subsidiaries to keep, observe, perform and fulfill its obligations under this Indenture and further
stating, as to each such Officer signing such certificate, that, to the best of his or her knowledge, the Issuers during such preceding fiscal year have kept, observed, performed and fulfilled, and have caused each of the Restricted Subsidiaries to
keep, observe, perform and fulfill each and every such covenant contained in this Indenture and no Event of Default occurred during such year and at the date of such certificate there is no Event of Default which has occurred and is continuing or,
if such signers do know of such Event of Default, the certificate shall describe its status with particularity and shall state what action the Issuers are taking or propose to take in respect thereof and that, to the best of his or her knowledge, no
event has occurred and remains by reason of which payments on the account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action each is taking or proposes to
take with respect thereto. The Officers’ Certificate shall also notify the Trustee should either or both of the Issuers elect to change the manner in which either of them fix their fiscal year end. For purposes of this Section 1016(a),
such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture. 
 (b)
When any Default has occurred and is continuing under this Indenture, or if the trustee for or the holder of any other evidence of Indebtedness of the Issuers or any Significant Subsidiary gives any notice or takes any other action with respect to a
claimed Default (other than with respect to Indebtedness in the principal amount of less than $25,000,000), the Issuers shall deliver to the Trustee by registered or certified mail or facsimile transmission (to be followed promptly by delivery of
the original copy thereof) an Officers’ Certificate specifying such event, notice or other action within five Business Days of its occurrence. 
 SECTION 1017. Limitation on Guarantees of Certain Indebtedness. 
 (a)
Mediacom Broadband LLC shall not (i) permit any Restricted Subsidiary to guarantee any Indebtedness of either Issuer other than the Notes (the “Other Indebtedness”) or (ii) pledge any inter-company Indebtedness representing
obligations of any of its Restricted Subsidiaries to secure the payment of Other Indebtedness, in each case unless such Restricted Subsidiary, the Issuers and the Trustee execute and deliver a supplemental indenture pursuant to Section 901
causing such Restricted Subsidiary to guarantee (the “Restricted Subsidiary Guarantee”) the Issuers’ obligations under this Indenture and the Notes to the same extent that such Restricted Subsidiary guaranteed the Issuers’
obligations under the Other Indebtedness (including waiver of subrogation, if any). Thereafter, such Restricted Subsidiary shall be a Guarantor for all purposes of this Indenture. 

  
 -88-

 (b) The guarantee of a Restricted Subsidiary shall be released upon: (i) the sale of
all of the Equity Interests, or all or substantially all of the assets, of the applicable Guarantor (in each case other than to Mediacom Broadband LLC or a Subsidiary); (ii) the designation by Mediacom Broadband LLC of the applicable Guarantor
as an Unrestricted Subsidiary pursuant to Section 1018; or (iii) the release of the guarantee of such Guarantor with respect to the obligations which caused such Guarantor to deliver the Restricted Subsidiary Guarantee in accordance with
the preceding paragraph, in each case in compliance with this Indenture (including, without limitation, in the event of a sale of Equity Interests or assets described in clause (i) above, that the Net Cash Proceeds are applied in accordance
with the requirements of Section 1013). 
 (c) The Trustee shall, at the sole cost and expense of the Issuers, upon receipt
of a request by the Issuers accompanied by an Officers’ Certificate certifying as to the compliance with paragraph (b) of this Section and, with respect to clause (i) or (ii) of paragraph (b) of this Section, upon receipt at
the reasonable request of the Trustee of an Opinion of Counsel that the provisions of this Section have been complied with, deliver an appropriate instrument evidencing such release. Any Guarantor not so released remains liable for the full amount
of principal of and interest on the Notes and the other obligations of the Issuers provided herein. 
 SECTION 1018.
Designation of Unrestricted Subsidiaries. 
 (a) Mediacom Broadband LLC may designate any Subsidiary (including, without
limitation, any newly acquired or newly 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. 
 (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 (other than Permitted Investments) in any Unrestricted Subsidiary; or (y) maintain or preserve the financial condition of any Unrestricted Subsidiary or cause any Unrestricted Subsidiary to achieve any specified levels of
operating results; or (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. 

(c) Mediacom Broadband LLC may revoke any Designation of a Subsidiary as an Unrestricted Subsidiary (a “Revocation”) if:
(a) no Default or Event of Default shall have occurred and be 

  
 -89-

 
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. 
 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. 

  
 -90-

 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, 
 (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. 

  
 -91-

 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. 

  
 -92-

 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:

the outstanding Notes will not recognize income, gain or loss 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; 
 (iii) Mediacom Broadband LLC shall have
delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, the Holders of the outstanding Notes will not recognize income, gain or loss

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;

 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

 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 Thirteen 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. 
 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 

  
 -96-

 
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.
