1.   CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

     Basis of Presentation
     The condensed  consolidated  balance sheet as of December 31, 1997 has been
     condensed from the audited  consolidated balance sheet as of that date. The
     condensed consolidated balance sheet as of March 31, 1998 and the condensed
     consolidated  statements of operations and accumulated  deficit and of cash
     flows for the three months ended March 31, 1998 and 1997 have been prepared
     by Comcast  Corporation  (the  "Company")  and have not been audited by the
     Company's  independent   auditors.  In  the  opinion  of  management,   all
     adjustments (which include only normal recurring  adjustments) necessary to
     present fairly the financial position, results of operations and cash flows
     as of March 31, 1998 and for all periods presented have been made.

     Certain information and note disclosures normally included in the Company's
     annual financial  statements prepared in accordance with generally accepted
     accounting  principles  have been  condensed  or omitted.  These  condensed
     consolidated  financial  statements  should be read in conjunction with the
     financial  statements and notes thereto included in the Company's  December
     31, 1997 Annual Report on Form 10-K filed with the  Securities and Exchange
     Commission.  The results of operations  for the period ended March 31, 1998
     are not necessarily indicative of operating results for the full year.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     New Accounting Pronouncement
     In June 1997, the Financial  Accounting Standards Board issued Statement of
     Financial Accounting  Standards ("SFAS") No. 130, "Reporting  Comprehensive
     Income."  This  statement,  which  establishes  standards for reporting and
     disclosure  of  comprehensive  income,  is effective for interim and annual
     periods beginning after December 15, 1997. The Company adopted SFAS No. 130
     effective  January 1, 1998. Total  comprehensive  loss for the three months
     ended  March  31,  1998  and  1997  was $6.7  million  and  $77.2  million,
     respectively.  Total  comprehensive  income  (loss)  includes  net  (loss),
     unrealized  gains (losses) on marketable  securities  and foreign  currency
     translation gains (losses) for the periods presented.

     Loss for Common Stockholders Per Common Share
     Loss for common  stockholders  per common share is computed by dividing net
     loss, after deduction of preferred stock dividends, by the weighted average
     number of common shares outstanding during the period.

     For the three months ended March 31, 1998 and 1997, the Company's potential
     common  shares of 43.3  million  shares  and 39.4  million  shares  have an
     antidilutive  effect on loss for common  stockholders per common share and,
     therefore,  have not been used in determining  the total  weighted  average
     number of common shares outstanding.

     Reclassifications
     Certain  reclassifications  have  been  made to the  prior  year  condensed
     consolidated  financial statements to conform to those classifications used
     in 1998.

3.   SIGNIFICANT EVENTS

     Sale of Comcast UK Cable
     On  February  4,  1998,  Comcast UK Cable  Partners  Limited  ("Comcast  UK
     Cable"),  a  consolidated  subsidiary  of  the  Company,   entered  into  a
     definitive  agreement  to be  acquired  by  NTL  Incorporated  ("NTL"),  an
     alternative  telecommunications  company  in  the  United  Kingdom  ("UK").
     Pursuant to certain  conditions,  the Company may receive up to 4.8 million
     shares of NTL common  stock in exchange for all of the shares of Comcast UK
     Cable  held by the  Company  (the "NTL  Transaction").  Certain  conditions
     agreed to in the NTL Transaction restrict the Company's ability to sell the
     NTL common  stock to be received for a period of 180 days after the closing
     of the NTL  Transaction.  The NTL Transaction is expected to close in 1998,
     subject to the receipt of necessary  regulatory and shareholder  approvals,
     the consent of the  bondholders of Comcast UK Cable and NTL, as well as the
     consent of certain NTL bank lenders. As of March 31, 1998 and for the three
     months then  ended,  the assets and  revenues  of Comcast UK Cable  totaled
     $857.5 million and $29.0 million, respectively.

     AT&T Acquisition of TCGI
     On January 8, 1998,  AT&T  Corporation  ("AT&T")  entered into a definitive
     merger agreement with Teleport  Communications  Group, Inc. ("TCGI").  Upon
     closing of the merger (the "AT&T Transaction"),  the Company is expected to
     receive 24.2 million shares of  unregistered  AT&T common stock in exchange
     for all of the  shares of TCGI held by the  Company  (see Note 4). The AT&T
     shares to be received  are subject to certain  rights which would allow the
     Company to effect a registration of such shares.  These registration rights
     are subject to  postponement  by AT&T and other  rights of AT&T which could
     delay a registration for a period greater than one year from the closing of
     the AT&T  Transaction.  The AT&T  Transaction is expected to close in 1998,
     subject to the receipt of necessary regulatory and shareholder approvals.

     Equity Method
     The Company records its proportionate interests in the net income (loss) of
     substantially  all of its  investees,  other  than  the UK  Investees  (see
     below), three months in arrears.  The Company holds interests  representing
     less than 20% of the total  outstanding  ownership  interests in certain of
     its equity  method  investees.  The equity method of accounting is utilized
     for  these  investments  based  on the  type of  investment  (e.g.  general
     partnership interest), board representation, participation in a controlling
     investor group,  significant  shareholder  rights or a combination of these
     and  other  factors.   The  Company's   recorded   investments  exceed  its
     proportionate  interests in the book value of the  investees' net assets by
     $95.8 million as of March 31, 1998 (primarily  related to its investment in
     Sprint PCS (see  below)).  Such excess is being  amortized to equity in net
     income  or  loss,  primarily  over a  period  of  twenty  years,  which  is
     consistent with the estimated lives of the underlying  assets. The original
     cost of  investments  accounted for under the equity method  totaled $1.356
     billion and $1.454  billion as of March 31,  1998 and  December  31,  1997,
     respectively.

          the Company accounted for its investment in E! Entertainment under the
          equity method since the date of initial  investment  (the  "Cumulative
          Charge").    Since   the   Company's   proportionate   share   of   E!
          Entertainment's  cumulative  losses  was in  excess  of the  Company's
          historical cost basis in E! Entertainment and as the Company was under
          no contractual obligation to fund the losses of E! Entertainment,  the
          Cumulative  Charge was limited to the Company's  historical cost basis
          of $12.1  million.  Such amount is included in equity in net losses of

     Sprint  PCS.   The  Company,   Tele-Communications,   Inc.   ("TCI"),   Cox
     Communications, Inc. ("Cox") and Sprint Corporation ("Sprint," and together
     with the Company, TCI and Cox, the "Parents"),  and certain subsidiaries of
     the  Parents  (the   "Partner   Subsidiaries"),   engage  in  the  wireless
     communications  business  through a limited  partnership  known as  "Sprint
     Spectrum" or "Sprint PCS." The Company made its initial  investment in 1994
     and, as of March 31, 1998, holds a general and limited partnership interest
     of 15% in Sprint PCS. The  Company's  investment in Sprint PCS is accounted
     for under the equity  method  based on the  Company's  general  partnership
     interest and its representation on the partnership's board.

     The Partner  Subsidiaries have committed to contribute $4.2 billion in cash
     to Sprint PCS through 1999, of which the Company's share is $630.0 million.
     Of this funding requirement,  the Company has made total cash contributions
     to Sprint  PCS of  $609.5  million  through  April 30,  1998.  The  Company
     anticipates  that Sprint PCS'  capital  requirements  over the next several
     years will be significant.  Requirements in excess of committed capital may
     be funded by Sprint PCS  through  external  financing,  including,  but not
     limited to, vendor financing,  bank financing and securities offered to the
     public.

     The  proposed  budget for 1998 for Sprint PCS has not yet been  approved by
     the partnership  board, which has resulted in the occurrence of a "Deadlock
     Event" as of January 1, 1998 under the partnership  agreement.  If the 1998
     proposed budget is not approved through resolution  procedures set forth in
     the partnership  agreement,  certain specified  buy/sell  procedures may be
     triggered  which may result in an increase in or the sale of the  Company's
     interest, or, in limited circumstances, the sale of Sprint PCS. Discussions
     among the partners about  restructuring  their  interests in Sprint PCS are
     ongoing.  However,  there is no certainty the discussions  will result in a
     change to the partnership structure.

     TCGI.  In  November  1997,  TCGI filed a  registration  statement  with the
     Securities and Exchange Commission to sell 7.3 million shares of TCGI Class
     A Stock  (the  "TCGI  Offering").  As a result  of the TCGI  Offering,  the
     Company  recognized a $59.6 million increase in its proportionate  share of
     TCGI's net assets as a gain from equity offering of affiliate. Such pre-tax
     gain is included  in the  Company's  condensed  consolidated  statement  of
     operations  and  accumulated  deficit for the three  months ended March 31,
     1998 as the Company  records its  proportionate  share of TCGI's net losses
     one quarter in arrears.

     As of March 31, 1998,  the Company owns 25.6 million shares of TCGI Class B
     Stock representing a 20.1% voting interest and a 14.7% equity interest (see
     Note 3). The Company  continues  to account for its  interest in TCGI under
     the equity method based on its voting interest  maintained through the TCGI
     Class B Stock,  its  representation  on TCGI's board of  directors  and its
     participation in a TCGI stockholder  agreement granting certain rights to a
     control group.

     UK Investees.  As of March 31, 1998,  Comcast UK Cable (see Note 3) holds a
     27.5% interest in Birmingham Cable Corporation Limited and a 50.0% interest
     in Cable London PLC.

     Comcast-Spectacor.  Effective  January 1,  1998,  the  Company's  condensed
     consolidated   financial   statements   include  the  accounts  of  Comcast
     Spectacor,  L.P.  ("Comcast-Spectacor"),  an affiliate previously accounted
     for under the equity method, due to certain call rights held by the Company
     which became exercisable effective January 16, 1998.

     Other.  The Company's other equity investees  include  investments in cable
     communications   (including   Garden  State   Cablevision   L.P.,  a  cable
     communications  company  serving more than 209,000  subscribers as of March
     31, 1998 in the State of New Jersey),  direct broadcast  satellite  ("DBS")
     services via Primestar  (see below),  cellular/PCS  telecommunications  and
     content providers.  The Company does not consider these other equity method
     investments to be individually  significant to its  consolidated  financial
     position, results of operations or liquidity.

     Restructuring of Primestar's Operations.  As of March 31, 1998, the Company
     held a 10.4% general and limited partnership interest in PRIMESTAR Partners
     L.P.  ("Primestar"),  which  is  principally  engaged  in the  business  of
     acquiring,  originating and/or providing  television  programming  services
     delivered by satellite  through a network of  distributors,  including  the
     Company, throughout the United States ("US").

     The Company,  through a wholly owned subsidiary,  distributed the Primestar
     DBS service (the "Primestar Service") to subscribers within specified areas
     of 19 states in the US. As of March 31,  1998,  the  Company  provided  the
     Primestar Service to more than 189,000 subscribers.

     On February 6, 1998,  the Company  entered  into a Merger and  Contribution
     Agreement (the "Merger and Contribution  Agreement") with Primestar and the
     affiliates  of each of the  other  partners  of  Primestar,  including  TCI
     Satellite Entertainment, Inc. ("TSAT"), a publicly-traded company, pursuant
     to which the Company's DBS operations,  the Company's partnership interests
     in Primestar and the Primestar partnership interests and the DBS operations
     of the other  partners of Primestar  were to be  consolidated  into a newly
     formed  company  ("New  Primestar").  Under  the  terms of the  Merger  and
     Contribution Agreement,  which closed on April 1, 1998, in exchange for the
     Company's DBS operations and equity  interest in Primestar,  New Primestar,
     through a series of  transactions,  assumed  $74.7 million of the Company's
     debt and the Company  received 9.5% of New Primestar  common  equity,  both
     subject to adjustment  based on the number of the Company's  subscribers to
     the Primestar Service,  inventory amounts and other factors.  Subsequent to
     the Merger and Contribution Agreement, New Primestar repaid indebtedness of
     $74.7 million to the Company. Subject to receipt of regulatory approval and
     other  conditions,  TSAT  will  merge  with  and into  New  Primestar  in a
     transaction in which TSAT's outstanding common shares will be exchanged for
     common  shares of New  Primestar.  As of March  31,  1998 and for the three
     months then ended,  the assets and revenues of the Company's DBS operations
     totaled $148.1 million and $33.7 million, respectively.

     In June 1997, Primestar entered into an agreement with The News Corporation
     Limited, MCI  Telecommunications  Corporation and American Sky Broadcasting
     LLC ("ASkyB"),  pursuant to which Primestar (or, under certain  conditions,
     New Primestar)  will acquire  certain  assets  relating to a high-power DBS
     business (the "ASkyB Transaction"). In exchange for such assets, ASkyB will
     receive  non-voting  securities of New Primestar  that will be  convertible
     into  non-voting  common stock of New  Primestar,  and,  accordingly,  will
     reduce  the  Company's   common   equity   interest  in  New  Primestar  to
     approximately 7% on a fully diluted basis, subject to adjustment.

     The ASkyB Transaction is expected to close in 1998,  subject to the receipt
     of all  necessary  governmental  and  regulatory  approvals,  including the
     approval  of  the  Federal  Communications  Commission.  There  can  be  no
     assurance  that such  approvals  will be  obtained.  On May 12,  1998,  the
     Antitrust  Division of the  Department  of Justice filed a Complaint in the
     United  States  District  Court for the  District  of  Columbia  seeking to
     permanently enjoin the ASkyB Transaction, or, in the alternative, requiring
     that the cable stockholders of New Primestar, including the Company, divest
     their ownership interests in New Primestar.

     Fair Value Method
     The Company  holds  unrestricted  equity  investments  in certain  publicly
     traded  companies,  with an  historical  cost of $132.1  million and $130.0
     million as of March 31,  1998 and  December  31,  1997,  respectively.  The
     Company has recorded these  investments,  which are classified as available
     for sale,  at their  estimated  fair  values of $458.3  million  and $346.5
     million as of March 31,  1998 and  December  31,  1997,  respectively.  The
     unrealized  pre-tax  gains as of March 31,  1998 and  December  31, 1997 of
     $326.2 million and $216.5 million, respectively,  have been reported in the
     Company's   condensed   consolidated   balance  sheet  as  a  component  of
     stockholders'  equity, net of related deferred income tax expense of $114.1
     million and $75.8 million, respectively.

5.   LONG-TERM DEBT

     Redemption of 1 1/8% Debentures
     In March 1998,  the Company  completed the redemption of its $541.9 million
     principal amount 1 1/8% discount  convertible  subordinated  debentures due
     2007 (the "1 1/8%  Debentures").  The Company issued 10.4 million shares of
     its  Class A  Special  Common  Stock  upon  conversion  of  $540.2  million
     principal amount of 1 1/8% Debentures  while $1.7 million  principal amount
     of 1 1/8% Debentures was redeemed for cash at a redemption price of 67.112%
     of  the  principal   amount,   together  with  accrued  interest   thereon.
     Stockholders'  equity was increased by the full amount of 1 1/8% Debentures
     converted plus accrued interest,  less unamortized debt acquisition  costs.
     Unamortized  debt  acquisition  costs  related  to  the 1  1/8%  Debentures
     redeemed for cash were not significant. The issuance of the

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

Overview

The Company has  experienced  significant  growth in recent  years both  through
strategic  acquisitions and growth in its existing  businesses.  The Company has
historically  met its cash  needs for  operations  through  its cash  flows from
operating   activities.   Cash   requirements   for   acquisitions  and  capital
expenditures have been provided through the Company's  financing  activities and
sales of long-term  investments,  as well as its existing cash, cash equivalents
and short-term investments.

General Developments of Business

See Note 3 to the Company's condensed consolidated financial statements included
in Item 1.

Liquidity and Capital Resources

Cash, Cash Equivalents and Short-term Investments
The  Company  has  traditionally  maintained  significant  levels of cash,  cash
equivalents  and  short-term   investments  to  meet  its  short-term  liquidity
requirements.  Cash, cash equivalents and short-term investments as of March 31,
1998 were $703.0 million.  As of March 31, 1998, $442.9 million of the Company's
cash,  cash  equivalents  and  short-term  investments  is  restricted to use by
subsidiaries of the Company under contractual or other  arrangements,  including
$164.1 million which is restricted to use by Comcast UK Cable  Partners  Limited
("Comcast UK Cable"), a consolidated subsidiary of the Company.

The Company's cash  equivalents and short-term  investments are recorded at cost
which  approximates  their  fair  value.  As  of  March  31,  1998,   short-term
investments have a weighted average maturity of approximately three months.

Investments
See Notes 3 and 4 to the Company's condensed  consolidated  financial statements
included in Item 1.

The Company does not have any significant  contractual  commitments with respect
to any of its investments.  However, to the extent the Company does not fund its
investees'  capital  calls,  it  exposes  itself to  dilution  of its  ownership
interests. The Company continually evaluates its existing investments as well as
new investment opportunities.

Financing
Other  than the  acquisition  of the  cable  television  operations  of the E.W.
Scripps  Company in  November  1996,  the Company  has  historically  utilized a
strategy of  financing  its  acquisitions  through  senior debt at the  acquired
operating  subsidiary level.  Additional financing has also been obtained by the
Company through the issuance of subordinated  debt at the  intermediate  holding
company and parent  company  levels and through  public  offerings of subsidiary
stock and debt  instruments.  As of March 31, 1998 and December  31,  1997,  the
Company's  long-term debt,  including  current  portion,  was $6.756 billion and
$6.691 billion,  respectively,  of which 21.7% and 17.1%,  respectively,  was at
variable  rates. As of April 30, 1998,  certain  subsidiaries of the Company had
unused  lines of credit of $1.228  billion.  The  availability  and use of these
unused  lines of credit is  restricted  by the  covenants  of the  related  debt
agreements and to subsidiary  general purposes and dividend  declaration.  As of
March 31, 1998 and December 31, 1997, the Company's  effective  weighted average
interest  rate  on  its  long-term  debt   outstanding   was  8.42%  and  8.36%,
respectively.

In March 1998,  the  Company  completed  the  redemption  of its $541.9  million
principal amount 1 1/8% discount  convertible  subordinated  debentures due 2007
(the "1 1/8% Debentures"). The Company issued 10.4 million shares of its Class A
Special  Common Stock upon  conversion of $540.2 million  principal  amount of 1
1/8%  Debentures  while $1.7 million  principal  amount of 1 1/8% Debentures was
redeemed  for cash at a  redemption  price of 67.112% of the  principal  amount,
together with accrued interest  thereon.  Stockholders'  equity was increased by
the full amount of 1 1/8%  Debentures  converted  plus  accrued  interest,  less
unamortized debt acquisition  costs.  Unamortized debt acquisition costs related
to the 1 1/8% Debentures redeemed for cash were not significant. The issuance of
the Company's Class A Special

                          QUARTER ENDED MARCH 31, 1998


Common  Stock  upon  conversion  of the 1 1/8%  Debentures  had no impact on the
Company's  condensed  consolidated  statement  of cash flows due to its  noncash
nature.

                            -------------------------

The telecommunications  industry,  including cable and cellular  communications,
and the electronic  retailing industry are experiencing  increasing  competition
and rapid technological changes. The Company's future results of operations will
be affected by its  ability to react to changes in the  competitive  environment
and by its ability to implement new technologies.  However, the Company believes
that competition,  technological  changes and its history of significant  losses
will not significantly affect its ability to obtain financing.

The Company  believes  that it will be able to meet its  current  and  long-term
liquidity and capital  requirements,  including fixed charges,  through its cash
flows from operating  activities,  existing cash, cash  equivalents,  short-term
investments and lines of credit and other external financing.

Statement of Cash Flows

Cash and cash  equivalents  increased  $257.4  million as of March 31, 1998 from
December  31,  1997 and  increased  $123.6  million  as of March  31,  1997 from
December 31, 1996. Changes in cash and cash equivalents resulted from cash flows
from operating, financing and investing activities which are explained below.

Net cash provided by operating  activities amounted to $303.1 million and $197.4
million for the three  months ended March 31, 1998 and 1997,  respectively.  The
increase of $105.7 million is  principally  due to the increase in the Company's
operating  income  before   depreciation  and  amortization   (see  "Results  of
Operations")  and  changes  in  working  capital  as a result  of the  timing of
receipts  and  disbursements,  including  the  effects of the  consolidation  of
Comcast  Spectacor,  L.P.  ("Comcast-Spectacor")  effective January 1, 1998 (see
Note 4 to the Company's condensed  consolidated financial statements included in
Item  1)  and  the  acquisition  of  E!  Entertainment  Television,   Inc.  ("E!
Entertainment") on March 31, 1997 (the "E! Acquisition").

Net cash provided by financing  activities  was $215.0 million and $85.2 million
for the three  months  ended March 31, 1998 and 1997,  respectively.  During the
three months  ended March 31,  1998,  the Company  borrowed  $965.2  million and
repaid $746.8 million of its long-term  debt,  primarily in connection  with the
refinancing  of certain  subsidiary  indebtedness  in March 1998.  In  addition,
during the three months ended March 31, 1998,  the Company had net  issuances of
$5.8 million of its common stock and paid cash  dividends of $8.9 million on its
common  stock and Class A Preferred  Stock.  During the three months ended March
31, 1997,  the Company  borrowed  $192.8  million,  including  $132.8 million in
connection  with the E!  Acquisition,  and repaid $90.9 million of its long-term
debt.  In addition,  during the three  months ended March 31, 1997,  the Company
made net repurchases of $7.0 million of its common stock and paid cash dividends
of $7.9 million on its common stock and Class A Preferred Stock.

Net cash used in investing  activities was $260.7 million and $159.0 million for
the three months ended March 31, 1998 and 1997,  respectively.  During the three
months ended March 31,  1998,  net cash used in  investing  activities  includes
acquisitions, net of cash acquired, of $136.9 million, investments in affiliates
of $58.3 million and capital expenditures of $199.1 million,  offset by proceeds
from the sales of  short-term  investments  and call options of $152.7  million.
During  the three  months  ended  March  31,  1997,  net cash used in  investing
activities includes the E! Acquisition, net of cash acquired, of $116.5 million,
investments  in affiliates of $32.4 million and capital  expenditures  of $180.0
million,  offset  by  proceeds  from  the  sales  of  short-term  and  long-term
investments  and a  distribution  from an  investee  of $150.4  million  and the
repayment  of a $25.2  million  loan to Sprint PCS (see Note 4 to the  Company's
condensed consolidated financial statements included in Item 1).

Results of Operations

The effects of the Company's recent acquisitions, as well as increased levels of
capital  expenditures,  were to increase  the  Company's  revenues  and expenses
resulting  in  increases  in  its  operating  income  before   depreciation  and
amortization,  depreciation expense,  amortization expense and interest expense.
In addition, the Company's equity in net losses of

certain of the Company's equity investees (see "Consolidated Analysis").

(1)  Operating income before  depreciation and amortization is commonly referred
     to in the Company's  businesses as "operating  cash flow."  Operating  cash
     flow is a measure of a company's  ability to  generate  cash to service its
     obligations, including debt service obligations, and to finance capital and
     other  expenditures.  In part due to the  capital  intensive  nature of the
     Company's  businesses  and the  resulting  significant  level  of  non-cash
     depreciation  expense  and  amortization  expense,  operating  cash flow is
     frequently  used  as one of  the  bases  for  comparing  businesses  in the
     Company's industries, although the Company's measure of operating cash flow
     may not be  comparable  to similarly  titled  measures of other  companies.
     Operating  cash flow does not purport to  represent  net income or net cash
     provided  by  operating  activities,  as  those  terms  are  defined  under
     generally accepted accounting  principles,  and should not be considered as
     an  alternative  to such  measurements  as an  indicator  of the  Company's
     performance.  See  "Statement  of Cash Flows" above for a discussion of net
     cash provided by operating activities.

Of the $40.1 million  increase in service income for the three month period from
1997 to 1998, $8.5 million is attributable to subscriber  growth,  $24.3 million
relates to changes in rates,  $3.9  million is  attributable  to growth in cable
advertising sales and $3.4 million relates to other product offerings.

Of the $21.0 million increase in operating,  selling, general and administrative
expenses  for the  three  month  period  from  1997 to 1998,  $13.2  million  is
attributable  to  increases  in the  costs of cable  programming  as a result of
changes in rates,  subscriber  growth and  additional  channel  offerings,  $2.0
million is attributable to growth in advertising  sales and $5.8 million results
from  increases in the cost of labor,  other volume  related  expenses and costs
associated with new product offerings. It is anticipated that the Company's cost
of cable  programming  will  increase in the future as cable  programming  rates
increase and additional sources of cable programming become available.

</TABLE>

The increase in net sales from  electronic  retailing  of $64.9  million for the
three month period from 1997 to 1998 is primarily attributable to the effects of
a 7.5%  increase in the average  number of homes  receiving  QVC services in the
United  States  ("US")  and a 13.7%  increase  in the  average  number  of homes
receiving QVC services in the United Kingdom ("UK").

                          QUARTER ENDED MARCH 31, 1998


The  increase  in cost of goods  sold from  electronic  retailing  is  primarily
related to the growth in net sales.

Of the increase in operating,  selling,  general and administrative  expenses of
$9.2  million for the three  month  period  from 1997 to 1998,  $6.3  million is
attributable  to higher  variable  costs  associated  with the increase in sales
volume and $2.8 million is  attributable  to increased  personnel and facilities
based costs  associated  with Studio Park,  QVC's new production and warehousing
facility which was opened in the fourth quarter of 1997. The remaining  increase
is primarily  attributable to expansion in the UK and Germany,  partially offset
by savings in marketing and promotional costs in the US.

</FN>
</TABLE>

Of the $1.3 million  increase in service  income for the three month period from
1997 to 1998,  $2.2 million is  attributable to subscriber  growth,  offset,  in
part, by a decrease of $0.9 million primarily  attributable to the increased use
of  promotional  and free  minute  plans  offered to  subscribers.  These  plans
generally have higher access fees and increase the minutes of use per subscriber
while lowering the average rate per minute of use.

The $0.5 million  decrease in  operating,  selling,  general and  administrative
expenses for the three month period from 1997 to 1998 is primarily  attributable
to  improved  bad debt  experience  as a result of  stronger  credit  procedures
offset,  in part, by an increase in commission  costs associated with more gross
sales in 1998.

Consolidated Analysis

The $41.6 million  increase in  depreciation  expense for the three month period
from  1997  to  1998  is  primarily  attributable  to  the  effects  of  capital
expenditures,  increased  losses  on  asset  disposals  in  connection  with the
Company's domestic cable communications rebuild activities and the consolidation
of Comcast-Spectacor.

The $13.3 million  increase in  amortization  expense for the three month period
from 1997 to 1998 is primarily  attributable to the effects of the consolidation
of Comcast-Spectacor.

The $14.3 million  increase in interest  expense for the three month period from
1997 to 1998 is attributable  to the effects of capitalized  interest during the
three months ended March 31, 1997, the consolidation of  Comcast-Spectacor,  the
E!  Acquisition  and an increase in the  Company's  effective  weighted  average
interest rate, offset, in part, by lower levels of debt outstanding. The Company
anticipates  that,  for  the  foreseeable  future,  interest  expense  will be a
significant  cost to the Company and will have a significant  adverse  effect on
the  Company's  ability to realize net  earnings.  The Company  believes it will
continue to be able to meet its obligations through its ability both to generate
operating  income before  depreciation  and  amortization and to obtain external
financing.

In March 1998,  the Company sold call  options  relating to its  investments  in
Tele-Communications,  Inc.  ("TCI"),  TCI Ventures Group, Inc. and Liberty Media
Group common stock  (together,  the "TCI  Stock") for $20.7  million.  Such call
options expire between March and September  1999.  During the three months ended
March 31, 1998, the Company

                          QUARTER ENDED MARCH 31, 1998


recorded  $14.6  million of  investment  expense  related to the increase in the
value of the call  options.  In  addition,  as of March 31,  1998,  the  Company
recorded an unrealized gain related to the TCI Stock, net of deferred income tax
expense,  of  $27.6  million  to  its  condensed   consolidated  balance  sheet,
representing the increase in fair value of the TCI Stock during the three months
ended March 31, 1998. In February 1997, the Company sold options to acquire 25.0
million shares of Nextel Communications,  Inc. ("Nextel") common stock to Nextel
for $25.0  million and  recognized  a pre-tax gain of $5.0  million.  In January
1997, the Company sold 1.27 million shares of Time Warner,  Inc. ("Time Warner")
common stock,  representing  the Company's  entire interest in Time Warner,  for
$48.6 million and recognized a pre-tax loss of $3.8 million. The pre-tax gain on
the sale of the Nextel  options and the pre-tax  loss on the sale of Time Warner
common stock are included in net  investment  expense  (income) in the Company's
condensed  consolidated  statement of operations and accumulated deficit for the
three months ended March 31, 1997.

The $59.6 million  increase in equity in net losses of affiliates  for the three
month  period from 1997 to 1998 is  primarily  due to the  effects of  increased
losses  incurred by Sprint  PCS.  Based on Sprint PCS'  current  operations  and
business plan, the Company  anticipates that its  proportionate  share of Sprint
PCS' losses will be  significant  in future periods (see Note 4 to the Company's
condensed  consolidated financial statements included in Item 1). As a result of
the E!  Acquisition,  the Company recorded a charge  representing the cumulative
amount  that  would  have  been  recorded  had  the  Company  accounted  for its
investment in E! Entertainment under the equity method since the date of initial
investment (the "Cumulative Charge"). Since the Company's proportionate share of
E!  Entertainment's  cumulative losses was in excess of the Company's historical
cost  basis in E!  Entertainment  and as the  Company  was under no  contractual
obligation to fund the losses of E!  Entertainment,  the  Cumulative  Charge was
limited to the Company's historical cost basis of $12.1 million.  Such amount is
included  in  equity in net  losses of  affiliates  in the  Company's  condensed
consolidated  statement  of  operations  and  accumulated  deficit for the three
months ended March 31, 1997.

In  November  1997,  Teleport   Communications  Group,  Inc.  ("TCGI")  filed  a
registration  statement with the Securities and Exchange  Commission to sell 7.3
million shares of TCGI Class A Stock (the "TCGI  Offering").  As a result of the
TCGI  Offering,   the  Company  recognized  a  $59.6  million  increase  in  its
proportionate  share of TCGI's  net  assets as a gain from  equity  offering  of
affiliate. Such pre-tax gain is included in the Company's condensed consolidated
statement of operations and accumulated deficit for the three months ended March
31, 1998 as the Company records its proportionate share of TCGI's net losses one
quarter in arrears.

The $11.4 million decrease in other expense for the three month period from 1997
to 1998 is primarily  attributable to the effects of fluctuations in the foreign
currency exchange rate.

The $9.3 million  decrease in income tax expense for the three month period from
1997 to 1998 is  primarily  a  result  of the  effects  of the  increase  in the
Company's loss before income tax expense and minority  interest and decreases in
non-deductible  foreign  losses  and  non-deductible  equity  in net  losses  of
affiliates.

The $6.8 million  decrease in minority  interest for the three month period from
1997 to 1998 is  primarily  attributable  to the  effects  of changes in the net
income   (loss)  of   Comcast   UK  Cable   and  QVC,   the   consolidation   of
Comcast-Spectacor and the E! Acquisition.

For the three months ended March 31, 1998 and 1997, the Company's  earnings (net
loss plus income tax expense, equity in net losses of affiliates,  fixed charges
(interest  expense) and  distributions  from  investees) were $199.0 million and
$150.4 million, respectively. Such earnings were adequate to cover the Company's
fixed  charges  (including  interest  capitalized  of $8.6 million for the three
months ended March 31, 1997) of $147.6  million and $141.9 million for the three
months  ended  March 31,  1998 and 1997,  respectively.  Fixed  charges  include
non-cash interest  expense,  net of interest  capitalized,  of $14.5 million and
$17.0 million for the three months ended March 31, 1998 and 1997, respectively.

The  Company  believes  that  its  losses  will  not  significantly  affect  the
performance of its normal business activities because of its existing cash, cash
equivalents and short-term investments, its ability to generate operating income
before  depreciation  and  amortization  and  its  ability  to  obtain  external
financing.

The  Company  believes  that  its  operations  are not  materially  affected  by
inflation.
