 (REVERSE OF SECURITY) 

COMCAST CORPORATION 
 4.450% Note
Due 2047 
 1.    Interest. 

COMCAST CORPORATION, a Pennsylvania corporation (the “Issuer”), promises to pay interest on the principal amount of this
Security at the rate per annum shown above. Cash interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from March 14, 2017. The Issuer will pay interest semi-annually
in arrears on each Interest Payment Date, commencing September 15, 2017. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

The Issuer shall pay interest on overdue principal from time to time on demand at the rate borne by the Securities and on overdue installments
of interest (without regard to any applicable grace periods) to the extent lawful. 
 2.    Method of Payment. 

The Issuer shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of
business on the Interest Record Date immediately preceding the Interest Payment Date notwithstanding any transfer or exchange of such Security subsequent to such Interest Record Date and prior to such Interest Payment Date. If any Interest Payment
Date, principal payment date, date of redemption or other payment date with respect to the Securities is not a Business Day (as defined below), the required payment of principal, premium, if any, or interest will be due on the next succeeding
Business Day as if made on the date that such payment was due, and no interest will accrue on that payment for the period from and after that Interest Payment Date, principal payment date, date of redemption or other payment date, as the case may
be, to the date of that payment on the next succeeding Business Day. Holders must surrender Securities to The Bank of New York Mellon (the “Trustee”) to collect principal payments. The Issuer shall pay principal and interest in
money of the United States that at the time of payment is legal tender for payment of public and private debts (“U.S. Legal Tender”). The payments of interest, and any portion of the principal shall be made by the Paying Agent, upon
receipt from the Issuer of immediately available funds by 4:00 p.m., London time one Business Day prior to the payment due date (or such other time as may be agreed to between the Issuer and the Paying Agent), directly to a Holder (by Federal funds
wire transfer or otherwise) if the Holder has delivered written instructions to the Paying Agent 15 days prior to such payment date requesting that such payment will be so made and designating the bank account to which such payments shall be so made
and in the case of payments of principal surrenders the same to the Trustee in exchange for a Security or Securities aggregating the same principal amount as the unredeemed principal amount of the Securities surrendered. All payment dates with
respect to the Securities, whether upon maturity, on any redemption date or on any Interest Payment Date, shall be determined in accordance with the time-zone applicable to The City of New York. 







 “Business Day” means any day, other than a Saturday or Sunday, which is not a
day on which banking institutions in The City of New York, London or Taipei, are authorized or required by law, regulation or executive order to close. 

3.    Paying Agent. 

Initially, The Bank of New York Mellon, London Branch will act as Paying Agent. The Issuer may change any Paying Agent without notice to the
Holders. 
 4.    Indenture. 

The Issuer issued the Securities under an Indenture dated as of September 18, 2013 by and among the Issuer, the guarantors named therein
and the Trustee, as amended by the First Supplemental Indenture dated as of November 17, 2015 by and among the Issuer, the guarantors named therein (the “Guarantors”) and the Trustee (together, the
“Indenture”). Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities 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. Sections 77aaa-77bbbb) (the “TIA”), as in effect on the date of the Indenture until such time as the Indenture is qualified under the TIA, and thereafter as in effect on the date on which the
Indenture is qualified under the TIA. Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and Holders of Securities are referred to the Indenture and the TIA for a statement of them. To the extent the terms
of the Indenture and this Security are inconsistent, the terms of the Indenture shall govern. 
 5.    Guarantees. 

Each Guarantor has irrevocably, fully and unconditionally guaranteed, jointly and severally, on an unsecured basis, the full and punctual
payment (whether at maturity, upon redemption or otherwise) of the principal of and interest on, and all other amounts payable under, the Securities, and the full and punctual payment of all other amounts payable by the Issuer under the Indenture,
subject to certain terms and conditions set forth in the Indenture. 
 6.    Denominations; Transfer; Exchange. 

The Securities are in registered form, without coupons, in denominations of $100,000 and multiples of $1,000 in excess thereof. A Holder shall
register the transfer of or exchange of Securities in accordance with the Indenture. The Issuer may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar
governmental charges payable in connection therewith as permitted by the Indenture. The Issuer is not required to transfer or exchange any Security selected for redemption during a period of fifteen (15) days before the electronic delivery or
mailing of a notice of redemption. 

  
 2 








 7.    Persons Deemed Owners. 

The registered Holder of a Security shall be treated as the owner of it for all purposes. 

8.    Unclaimed Funds. 

If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the
Issuer at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease. 

9.    Legal Defeasance and Covenant Defeasance. 

The Issuer and the Guarantors may be discharged from their respective obligations under the Securities and under the Indenture with respect to
the Securities except for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Securities and in the Indenture with respect to the Securities, in each case upon satisfaction of certain
conditions specified in the Indenture. 
 10.    Amendment; Supplement; Waiver. 

Subject to certain exceptions, the Securities and the provisions of the Indenture relating to the Securities may be amended or supplemented
with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding, and any existing Default or Event of Default or compliance with certain provisions may be waived with the consent of the
Holders of a majority in aggregate principal amount of the Securities then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Securities to, among other things, cure any
ambiguity, defect or inconsistency, provide for uncertificated Securities in addition to or in place of certificated Securities or comply with any requirements of the Commission in connection with the qualification of the Indenture under the TIA, or
make any other change that does not adversely affect the rights of any Holder of a Security. 
 11.    Restrictive
Covenants. 
 The Indenture contains certain covenants that, among other things, limit the ability of the Issuer and the Guarantors to incur
liens securing indebtedness, or to enter into sale and leaseback transactions, and of the Issuer to merge or sell all or substantially all of its assets. The limitations are subject to a number of important qualifications and exceptions. The Issuer
must annually report to the Trustee on compliance with such limitations. 
 12.    Optional Redemption. 

The Issuer will have the right at its option to redeem any of the Securities, in whole but not in part, on each March 15 on or after
March 15, 2020, on at least 30 days, 

  
 3 








 
but not more than 60 days, prior notice electronically delivered or mailed to the registered address of each Holder of the Securities, at a Redemption Price equal to 100% of the principal amount
of the Securities being redeemed plus any accrued interest to, but not including, the date of redemption. 

13.    Redemption for Tax Reasons. 

The Issuer will have right to redeem the Securities, in whole but not in part, on not less than 10 nor more than 60 days prior notice, at a
redemption price equal to 100% of their principal amount, together with any accrued and unpaid interest to, but not including, the date of redemption if, as a result of any change in, or amendment to, the laws (or any regulations or rulings
promulgated under the laws) of the United States (or any taxing authority in the United States), or any change in, or amendments to, an official position regarding the application or interpretation of such laws, regulations or rulings, which change
or amendment is announced or becomes effective on or after February 15, 2017, the Issuer becomes or, based upon a written opinion of independent counsel selected by the Issuer, will become obligated to pay additional amounts as described in
Section 14 herein under the heading “Payment of Additional Amounts.” 
 14.    Payment of Additional
Amounts. 
 The Issuer, will, subject to the exceptions and limitations set forth below, pay as additional interest on the Securities such
additional amounts as are necessary in order that the net payment by the Issuer or its paying agent of the principal of and interest on the Securities to a Holder who is not a United States person (as defined below), after withholding or deduction
for any present or future tax, assessment or other governmental charge (“Tax”) imposed by the United States or a taxing authority in the United States, will not be less than the amount provided in the Securities to be then due and
payable; provided, however, that the foregoing obligation to pay additional amounts shall not apply: 
 1.    to any Tax
that is imposed by reason of the Holder (or the beneficial owner for whose benefit such Holder holds the Securities), or a fiduciary, settlor, beneficiary, member or shareholder of the Holder if the Holder is an estate, trust, partnership or
corporation, or a person holding a power over an estate or trust administered by a fiduciary Holder, being considered as:

loan agreement entered into in the ordinary course of its trade or business; 
 2.    to any Holder that is not the sole
beneficial owner of the Securities, or a portion of the Securities, or that is a fiduciary, partnership or limited liability company, but only to the extent that a beneficial owner with respect to the Holder, a beneficiary or settlor with respect to
the fiduciary, or a beneficial owner or member of the partnership or limited liability company would not have been entitled to the payment of an additional amount had the beneficiary, settlor, beneficial owner or member received directly its
beneficial or distributive share of the payment; 
 3.    to any Tax that would not have been imposed but for the failure
of the Holder or any other person to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the Holder or beneficial owner of the
Securities, if compliance is required by statute, by regulation of the United States or any taxing authority therein or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such Tax;

9.    to any Tax imposed under Sections 1471 through 1474 of the Code (or any amended or successor provisions), any
current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement
entered into in connection with the implementation of such sections of the Code; or

bankruptcy Event of Default with respect to the Issuer or any of the Guarantors occurs and is continuing, all the Securities shall be immediately due and payable immediately in the manner and with the effect provided in the Indenture without any
notice or other action on the part of the Trustee or any Holder. Holders of Securities may not enforce the Indenture, the Securities or the Guarantees except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture, the
Securities or the Guarantees unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Securities then outstanding to
direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Securities notice of certain continuing Defaults or Events of Default if it determines that withholding notice is in their interest.

 16.    Trustee Dealings with Issuer. 

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal
with the Issuer as if it were not the Trustee. 
 17.    No Recourse Against Others. 

No stockholder, director, officer, employee or incorporator, as such, of the Issuer, any Guarantor or any successor Person thereof shall have
any liability for any obligation under the Securities, the Guarantees or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder of a Security by accepting a Security waives and
releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities. 

18.    Authentication. 

This Security shall not be valid until the Trustee manually signs the certificate of authentication on this Security.
