Item 4. Description of Securities

     The Comcast Corporation 1990 Restricted Stock Plan, as amended and restated
(the "Plan"), allows participants to elect to defer the receipt of restricted
stock to which restrictions have lapsed pursuant to the terms of an award and
the Plan (the "Deferral



Elections"). The following description of the Deferral Elections which may be
made pursuant to the Plan is qualified by reference to the Plan, which is
included as an exhibit to this Registration Statement. The shares of Class A
Special Common Stock, $1.00 par value (the "Common Stock") issuable under the
Plan are not described herein as they are registered pursuant to Section 12 of
the 1934 Act. Capitalized terms used in this Item 4 and not otherwise defined in
this Registration Statement shall have the respective meanings assigned to such
terms in the Plan. The Deferral Elections will be unsecured obligations of the
Registrant to pay the shares deferred in accordance with the terms of the Plan.
The Plan is administered by the Subcommittee on Performance Based Compensation
of the Compensation Committee of the Board of Directors of the Registrant (the
"Plan Administrator").

     Under the Plan, the Registrant will provide certain eligible management
employees with the opportunity to defer receipt of Common Stock, to which
forfeiture restrictions may lapse for a period of two to ten years from the
vesting date. A Deferral Election must generally be filed by the last day of the
second calendar year that precedes the vesting date. If restrictions on an award
of restricted stock do not lapse before the distribution date identified in a
Deferral Election because of a failure to satisfy any condition precedent, a
Deferral Election will be null and void. If applicable restrictions on Common
Stock may lapse within the same plan year as the plan year in which the award is
granted, an election to defer receipt of those shares will be effective if it is
filed on or before the earlier of the 30/th/ day following the date of grant or
the last day of the month that precedes the month on which the applicable
restrictions may lapse. The plan year is from January 3 to the next January 2.
Participants in the Plan may elect to re-defer receipt of any previously
deferred shares for an additional period of two to ten years if the election to
defer receipt is made on or before June 30/th/ of the calendar year preceding
the year in which the shares would otherwise be paid.

     Shares subject to a Deferral Election will be distributed by the Registrant
in accordance with the Plan. In general, if a participant's employment
terminates before the end of a deferral period, the participant will receive his
or her shares on the date stated in the Deferral Election form. However, if a
participant dies before the end of a deferral period, his or her estate or
beneficiary may elect to: (1) defer the payment date for two years from the
scheduled payment date, provided that the payment date may not be extended for
more than five years from the date of death or (2) accelerate the payment date
to the January 2 of the calendar year beginning after his or her death. If a
participant becomes disabled before the scheduled payment date, he or she may
elect to accelerate the payment to January 2 of the calendar year beginning
after he or she becomes disabled. If a participant retires before the end of a
deferral period, he or she may elect to defer the payment date for two years
from the scheduled payment date, provided that the payment date may not be
extended for more than five years from the date of retirement. The Plan
Administrator has the authority to determine whether the termination of a
participant's employment is a "retirement."

     The right to receive shares of Common Stock deferred under the Plan will at
all times represent the general obligation of the Registrant. Each participant
will be a general creditor of the Registrant with respect to his or her Deferral
Elections. Nothing contained in the Plan will be deemed to create an escrow,
trust, custodial account or fiduciary relationship of any kind. Furthermore,
nothing contained in the Plan or an award of restricted stock will be construed
to eliminate any priority or preferred position of a grantee in a bankruptcy
matter with

                                       -2-



respect to a claim for wages. The right to receive shares subject to a Deferral
Election will not be subject in any manner to attachment or other legal process,
nor is such right subject to anticipation, alienation, sale, transfer,
assignment or encumbrance.

     The Board of Directors of the Registrant has the authority to terminate the
Plan at any time. Furthermore, the Plan may be amended by the Board of Directors
or the Plan Administrator at any time. No award of restricted stock granted
under the Plan will be affected by any such termination or amendment without a
participant's written consent.

Item 5. Interests of Named Experts and Counsel

     None

Item 6. Indemnification of Directors and Officers

     Sections 1741 through 1750 of Subchapter D, Chapter 17, of the Pennsylvania
Business Corporation Law of 1988 (the "BCL") contain provisions for mandatory
and discretionary indemnification of a corporation's directors, officers and
other personnel, and related matters.

     Under Section 1741, subject to certain limitations, a corporation has the
power to indemnify directors and officers under certain prescribed circumstances
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred in connection with an action or
proceeding, whether civil, criminal, administrative or investigative, to which
any of them is a party by reason of his being a director, officer, employee or
agent of the corporation or serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise if he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
corporation and, with respect to any criminal proceeding, has no reasonable
cause to believe his conduct was unlawful. Under Section 1743, indemnification
is mandatory to the extent that the director, officer, employee or agent has
been successful on the merits or otherwise in defense of any action or
proceeding relating to third-party or derivative actions if the appropriate
standards of conduct are met.

     Section 1742 provides for indemnification in derivative actions except in
respect of any claim, issue or matter as to which the person has been adjudged
to be liable to the corporation unless and only to the extent that the proper
court determines upon application that, despite the adjudication of liability
but in view of all the circumstances of the case, the person is fairly and
reasonably entitled to indemnity for the expenses that the court deems proper.

     Section 1744 provides that, unless ordered by a court, any indemnification
under Section 1741 or 1742 shall be made by the corporation as authorized in the
specific case upon a determination that the representative met the applicable
standard of conduct set forth in those sections and such determination shall be
made: (1) by the board of directors by majority vote of a quorum of directors
not parties to the action or proceeding; (2) if a quorum is not obtainable and a
majority of disinterested directors so directs, by independent legal counsel; or
(3) by the shareholders.

                                       -3-



     Section 1745 provides that expenses incurred by an officer, director,
employee or agent in defending a civil or criminal action or proceeding may be
paid by the corporation in advance of the final disposition of such action or
proceeding upon receipt of an undertaking by or on behalf of such person to
repay such amount if it shall ultimately be determined that he is not entitled
to be indemnified by the corporation.

     Section 1746 provides generally that except in any case where the act or
failure to act giving rise to the claim for indemnification is determined by the
court to have constituted willful misconduct or recklessness, the
indemnification and advancement of expenses provided by this Subchapter of the
BCL shall not be deemed exclusive of any other rights to which a person seeking
indemnification or advancement of expenses may be entitled under any bylaw,
agreement vote of shareholders or disinterested directors or otherwise, both as
to action in his official capacity and as to action in another capacity while
holding that office. Section 1746 also provides that a corporation may create a
fund of any nature which may, but need not be, under the control of a trustee,
or otherwise secure or insure in any manner its indemnification obligations.

     Section 1747 grants a corporation the power to purchase and maintain
insurance on behalf of any director or officer against any liability incurred by
him in his capacity as officer or director, whether or not the corporation would
have the power to indemnify him against that liability under this Subchapter of
the BCL.

     Sections 1748 and 1749 extend the indemnification and advancement of
expenses provisions contained in Sections 1741 through 1750 of the BCL to
successor corporations in fundamental changes and to representatives serving as
fiduciaries of employee benefit plans.

     Section 1750 provides that the indemnification and advancement of expenses
provided by, or granted pursuant to, Sections 1741 through 1750 of the BCL
shall, unless otherwise provided when authorized or ratified, continue as to a
person who has ceased to be a director, officer, employee or agent and shall
inure to the benefit of the heirs and personal representatives of such person.

     Section 7-2 of the Registrant's By-laws provides that the Registrant will
indemnify any director or officer of the Registrant to the fullest extent
permitted by Pennsylvania law against all expense, liability and loss reasonably
incurred or suffered by such person in connection with any threatened pending or
completed action, suit or proceeding (a "Proceeding") involving such person by
reason of the fact that he or she is or was a director or officer of the
Registrant or is or was serving at the request or for the benefit of the
Registrant in any capacity for another corporation or other enterprise. No
indemnification pursuant to Section 7-2 may be made, however, in any case where
the act or failure to act giving rise to the claim for indemnification is
determined by a court to have constituted willful misconduct or recklessness.

     Section 7-2 further provides that the right to indemnification includes the
right to have the expenses incurred by the indemnified person in defending any
Proceeding paid by the Registrant in advance of the final disposition of the
Proceeding to the fullest extent permitted by Pennsylvania law. In addition,
Section 7-2 provides that the Registrant may purchase and maintain insurance for
the benefit of any person on behalf of whom insurance is permitted to be

                                       -4-



purchased by Pennsylvania law against any expense, liability or loss whether or
not the Registrant would have the power to indemnify such person under
Pennsylvania or other law. The Registrant may also purchase and maintain
insurance to insure its indemnification obligations, whether arising under the
By-laws or otherwise. Furthermore, Section 7-2 states that the Registrant may
create a fund of any nature or otherwise may secure in any manner its
indemnification obligations, whether arising under the By-laws or otherwise.
Indemnification pursuant to Section 7-2 shall continue as to an indemnified
person who has ceased to be a director or officer and shall inure to the benefit
of his heirs, executors and administrators.

     Section 7-3 of the Registrant's By-laws states that the provisions of the
By-laws relating to indemnification constitute a contract between the Registrant
and each of its directors and officers which may be modified as to any director
and officer only with that person's consent or as provided in Section 7-3.
Furthermore, any repeal or amendment of the indemnification provisions of the
By-laws adverse to any director or officer will apply only on a prospective
basis. In addition, no repeal or amendment of the By-laws may affect the
indemnification provisions of the By-laws so as to limit indemnification or the
advancement of expenses in any manner unless adopted by (a) the unanimous vote
of the directors of the Registrant then serving or (b) the affirmative vote of
shareholders entitled to cast at least 80% of the votes that all shareholders
are entitled to cast in the election of directors, provided that no such
amendment will have a retroactive effect inconsistent with the preceding
sentence.

     The Registrant has purchased directors and officers liability insurance for
its directors and officers.

Item 9. Undertakings

     The undersigned registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made
pursuant to this Registration Statement, a post-effective amendment to this
Registration Statement:

         (i)   To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

         (ii)  To reflect in the prospectus any facts or events arising after
the effective date of this Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in aggregate, represent
a fundamental change in the information set forth in this Registration
Statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which is registered) and any deviation from the low or high end of
the estimated maximum range may be reflected in the form of prospectus filed
with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in
volume and price represent no more than 20 percent change in the maximum
aggregate offering price set forth in "Calculation of Registration Fee" table in
the effective registration statement;

         (iii) To include any material information with respect to the plan of
distribution not previously disclosed in this Registration Statement or any
material change to such information in this Registration Statement;

     provided, however, that paragraphs (i) and (ii) above do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant to
Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated
by reference in this Registration Statement.

     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in this Registration Statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

                                       -6-



     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                                       -7-
