Combined Returns for the Taxable Year ending December 31, 1998 by their original
due  date.  For  purposes  of this  Section  4.2,  cooperation  includes  making
available all  instructions,  workpapers,  research,  data and notes of any kind
required for the completion of the Combined Return,  as well as making available
personnel to assist in



    










the combination effort. Personnel requirements, including the use of third party
contractors,  will be  negotiated  and agreed upon  between U S WEST and New U S
WEST.  Interviewing and hiring of third-party  contractors will be done jointly,
and costs of these  contractors  will be shared  equally.  Any software  license
costs  specifically  related to a separate entity shall be borne by that entity.
Where software license costs are not discernible as separate entity costs,  such
software  license  costs  will be shared  equally.  Due  dates  for  information
required for Combined  Returns will be  negotiated  between U S WEST and New U S
WEST and good faith efforts will be made to meet those dates.

                  4.3 Separate  Returns.  Any Separate  Return shall be prepared
and  caused to be filed by the  entity  required  by law to file  such  Separate
Return.

                  4.4  Cooperation;  Maintenance  and Retention of Records.  U S
WEST and New U S WEST shall,  and shall cause the MediaOne Group and the New U S
WEST Group  respectively  to, provide the requesting  party with such assistance
and  documents as may be reasonably  requested by such party in connection  with
(i) the preparation of any Tax Return, (ii) the conduct of any Proceeding, (iii)
any matter relating to Taxes of any member of the U S WEST  Consolidated  Group,
the New U S WEST Group or the MediaOne Group and (iv) any other matter that is a
subject of this Agreement. New U S WEST and U S WEST shall retain or cause to be
retained all Tax Returns,  schedules and workpapers, and all material records or
other  documents  relating  thereto,  until the  expiration  of the  statute  of
limitations  (including any waivers or extensions  thereof) of the Taxable Years
to which such Tax Returns and other documents  relate or until the expiration of
any  additional  period that any party  reasonably  requests,  in writing,  with
respect to specific material records or documents.  A party intending to destroy
any material  records or documents shall provide the other party with reasonable
advance notice and the  opportunity  to copy or take  possession of such records
and  documents.  The  parties  hereto  will  notify each other in writing of any
waivers or extensions of the applicable  statute of limitations  that may affect
the period for which the foregoing records or other documents must be retained.

                                    ARTICLE V

                         REFUNDS, AUDITS AND ADJUSTMENTS

                  5.1 Refunds of Taxes. Except as provided in Section 5.2 below,
New U S WEST  shall be  entitled  to all  Refunds  relating  to Taxes  (plus any
interest   thereon  received  with  respect  thereto  from  the  applicable  Tax
Authority)  for which New U S WEST is or may be liable  pursuant  to Articles II
and III of  this  Agreement,  and U S WEST  shall  be  entitled  to all  Refunds
relating to Taxes (plus any interest  thereon received with respect thereto from
the applicable Tax Authority) for which U S WEST is or may be liable pursuant to
the



    









provisions of Articles II and III of this Agreement.  A party receiving a Refund
to which  another  party is entitled  pursuant to this  Agreement  shall pay the
amount to which such other party is entitled (plus any interest thereon received
with respect  thereto from the applicable  Tax  Authority)  within ten (10) days
after the receipt of the Refund.

                  5.2 Carrybacks. (a) The carryback of any loss, credit or other
Tax attribute in any Post-Separation  Taxable Period shall be in accordance with
the provisions of the Code and Treasury  Regulations (and any applicable  state,
local or foreign laws or regulations).

                  (b) In the  event  that the New U S WEST  Group  realizes  any
loss, credit or other Tax attribute in any Post-Separation  Taxable Period, such
group  may  elect  to  carry  back  such  loss,  credit  or Tax  attribute  to a
Pre-Separation  Taxable  Period.  U S WEST shall  cooperate with New U S WEST in
seeking from the  appropriate  Tax  Authority any Refund that  reasonably  would
result  from such  carryback.  New U S WEST shall be  entitled to any Refund (or
other Tax  benefit)  realized by the  MediaOne  Group  (including  any  interest
thereon received from such Tax Authority) attributable to such carryback, within
ten (10)  business  days after such Refund (or other Tax  benefit) is  received;
provided,  however,  that U S WEST shall be entitled to any Refund (or other Tax
benefit)  that  results  from the  carryback  of a loss,  credit  or  other  Tax
attribute  by the MediaOne  Group from a Post-  Separation  Taxable  Period to a
Pre-Separation Taxable Period.

                  (c) Except as  otherwise  provided by  applicable  law, if the
MediaOne Group and the New U S WEST Group both may carry back a loss,  credit or
other Tax attribute to the same  Pre-Separation  Taxable Period,  any Refund (or
other Tax benefit)  resulting  therefrom shall be allocated between U S WEST and
New U S WEST  proportionately  based on the relative  amounts of the Refunds (or
other Tax  benefits)  to which the  MediaOne  Group and the New U S WEST  Group,
respectively,  would  have  been  entitled  had its  carrybacks  been  the  only
carrybacks to such Taxable Year.

                  (d) To the extent that the amount of a Refund to which a party
is entitled under this Section 5.2 is reduced by the applicable Tax Authority as
a result of the  offset of such  amount  against  a Tax  Liability  of the other
party, as allocated  under this Agreement,  the party which receives the benefit
of such offset shall  appropriately  compensate  the other party within ten (10)
days of receipt of such benefit.

                  5.3  Federal Audits and Adjustments.

                  (a)  Notification of Audit.  Each of U S WEST and New U S WEST
shall  give  written  notice  to the  other  party of any  audit of the U S WEST
Consolidated Group Tax Return for any Pre-Separation  Taxable Period or Straddle
Period within ten (10) business



    









days  after  receipt of written  notification  of such audit from the IRS.  Such
notice shall include a copy of the notification received from the IRS.

                  (b) Statute of  Limitations.  Any  extension of the statute of
limitations  for any  Pre-Separation  Taxable Period or Straddle Period shall be
with the mutual  agreement of U S WEST and New U S WEST.  Any dispute  regarding
the extension of the statute of limitations shall be resolved in accordance with
Section 6.13 of this Agreement.

                  (c)  Audit  Activity.  Each of U S WEST and New U S WEST  will
coordinate its respective  efforts with respect to audits of any  Pre-Separation
Taxable  Period  and any  Straddle  Period and will  furnish  the other with all
necessary  workpapers  and records to respond to audit  inquiries.  New U S WEST
will be responsible as agent for the U S WEST Consolidated  Group for day-to-day
contact with IRS agents  assigned to such audits.  U S WEST will be  responsible
for  responding to audit  inquiries  regarding  issues  primarily  affecting Tax
Liabilities  of the MediaOne  Group,  but will act through New U S WEST,  rather
than directly contacting the IRS with respect to such matters.

                  (d) Notification.  New U S WEST will provide timely reports to
U S WEST detailing significant activities,  information requests,  issues raised
or  resolved,  and any other  relevant  information,  such reports to be no less
frequent than quarterly.

                  (e) Proposed  Adjustments.  New U S WEST shall notify U S WEST
of any Adjustment to the U S WEST Consolidated Group Tax Returns within ten (10)
business days after receipt of notification of such Adjustment from the IRS. New
U S WEST  shall  include  in its  notice to U S WEST a copy of the  notification
received from the IRS.

                    (i)  Agreed  Issues.  New U S WEST will not  enter  into any
               agreement  with  the IRS as agent  for the U S WEST  Consolidated
               Group with respect to any Adjustment  without the written consent
               of U S WEST,  in those  cases where the  MediaOne  Group would be
               liable  for  more  than 50% of the  proposed  Tax  Liability  (as
               allocated under this Agreement)  attributable to such Adjustment.
               For purposes of this paragraph,  all determinations shall be made
               separately for each Adjustment.

                    (ii)  Unagreed  Issues.  In the  event U S WEST  and New U S
               WEST, as the case may be, do not agree to all  Adjustments  for a
               Taxable Year,  decisions  regarding the  procedures and preferred
               forum for contesting Adjustments on unagreed issues shall be made
               by whichever  of the MediaOne  Group or the New U S WEST Group is
               responsible  for more than 50% of the  cumulative  Tax  Liability
               attributable to such  Adjustments.  The party making the decision
               shall  consult  in good  faith  with the  other  party  and shall
               promptly notify the other party of its decision.



      











                    (iii)  Consent  Not  Required.   Notwithstanding  any  other
               provision  of this  Agreement,  if the IRS notifies U S WEST that
               the IRS will deal directly  with the MediaOne  Group with respect
               to its Tax  Liability,  U S WEST shall have full authority to act
               for the MediaOne  Group and resolve any issue  affecting  its Tax
               Liability  without  the  consent  of New U S WEST.  U S WEST will
               provide New U S WEST with a timely  report  summarizing  any such
               audit  activity,   such  report  to  be  no  less  frequent  than
               quarterly.

                  (f) Federal Refund  Claims.  If the New U S WEST Group desires
to file a claim for Refund  with  respect  to a Taxable  Year for which it was a
member of the U S WEST  Consolidated  Group,  it shall prepare and submit to U S
WEST the claim  for  Refund  and a  statement  specifying  the date on which the
statute of  limitations  for filing the Refund claim will expire.  U S WEST will
file the Refund  claim prior to the date  specified as the last day to claim the
Refund  if such a filing  is  commercially  reasonable,  and will take any other
appropriate action at New U S WEST's request necessary to secure the Refund.

                  (g) Litigation. Subject to the balance of this Section 5.3(g),
U S WEST and New U S WEST  jointly  shall  conduct all  Proceedings  relating to
Adjustments of the MediaOne Group and the U S WEST Group as allocated under this
Agreement.  U S WEST shall  have the  ability  to  control  the  conduct of such
Proceedings  with  respect to issues  relating  to an  Adjustment  for which the
MediaOne  Group would be liable for more than 50% of the proposed Tax  Liability
(as allocated under this Agreement)  attributable  to such  Adjustment.  New U S
WEST shall have the  ability to control  the  conduct of such  Proceedings  with
respect to issues  relating  to an  Adjustment  for which the New U S WEST Group
would be liable for more than 50% of the proposed Tax  Liability  (as  allocated
under  this  Agreement)  attributable  to such  Adjustment.  The party  with the
ability to control the conduct of all or a portion of the  Proceedings  pursuant
to this Section  5.3(g) shall consult in good faith with the other party,  which
other party shall be entitled to participate in all conferences,  meetings,  and
other matters related to the resolution of such Proceedings.

                  5.4  Audits and Adjustments Related to Combined Returns.

                  (a)  Notification of Audit.  Each of U S WEST and New U S WEST
shall give written  notice to the other party of any audit of a Combined  Return
for any  Pre-Separation  Taxable  Period  or  Straddle  Period  within  ten (10)
business  days after  receipt of written  notification  of such audit from a Tax
Authority.  Such notice shall include a copy of the  notification  received from
the relevant Tax Authority.

                  (b) Statute of  Limitations.  Any  extension of the statute of
limitations  for any  Pre-Separation  Taxable Period or Straddle Period shall be
with the mutual agreement of














U S WEST and New U S WEST. Any dispute regarding the extension of the statute of
limitations shall be resolved in accordance with Section 6.13 of this Agreement.

                  (c)  Audit  Activity.  Each of U S WEST and New U S WEST  will
coordinate its respective  efforts with respect to audits of Combined Returns of
any  Pre-Separation  Taxable Period and any Straddle Period and will furnish the
other with all necessary  workpapers and records to respond to audit  inquiries.
New U S WEST will be responsible as agent for any Combined Return for day-to-day
contact  with state Tax  Authorities  regarding  such  audits.  U S WEST will be
responsible  for  responding  to  audit  inquiries  regarding  issues  primarily
affecting Tax  Liabilities of the MediaOne  Group,  but will act through New U S
WEST,  rather than directly  contacting the  appropriate  Tax  Authorities  with
respect to such matters.

                  (d) Notification.  With respect to a Combined Return,  New U S
WEST will provide timely reports to U S WEST detailing  significant  activities,
information  requests,  issues  raised  or  resolved,  and  any  other  relevant
information, such reports to be no less frequent than quarterly.

                  (e) Proposed  Adjustments.  New U S WEST shall notify U S WEST
of any  Adjustment  to a Combined  Return  within ten (10)  business  days after
receipt  of  notification  of such  Adjustment  from the  applicable  state  Tax
Authority.  New U S WEST  shall  include in its notice to U S WEST a copy of the
notification received from such Tax Authority.

                        (i)  Agreed Issues. New U S WEST will not enter into any
agreement  with a state Tax  Authority as agent for U S WEST with respect to any
Adjustment in connection with a Combined Return without the written consent of U
S WEST in such cases where the MediaOne  Group would be liable for more than 50%
of the proposed Tax Liability (as allocated under this Agreement) at issue.  For
purposes of this paragraph, all determinations shall be made separately for each
Adjustment.

                       (ii)  Unagreed Issues.  In the event U S WEST and New U S
WEST,  as the case may be, do not agree to all  Adjustments  with  respect  to a
Combined  Return for a Taxable  Year,  decisions  regarding the  procedures  and
preferred  forum for contesting  Adjustments on unagreed issues shall be made by
whichever of the  MediaOne  Group or the New U S WEST Group is  responsible  for
more than 50% of the cumulative Tax Liability  attributable to such Adjustments.
The party making the decision  shall  consult in good faith with the other party
and shall promptly notify the other party of its decision.















                  (f) State Refund Claims.  If the New U S WEST Group desires to
file a claim for  Refund  with  respect  to a Taxable  Year for which it filed a
Combined  Return,  it shall  prepare and submit to U S WEST the claim for Refund
and a  statement  specifying  the date on which the statute of  limitations  for
filing the Refund claim will  expire.  U S WEST will file the Refund claim prior
to the date  specified if such filing is  commercially  reasonable and will take
any other  appropriate  action at New U S WEST's request necessary to secure the
Refund.

                  (g) State  Tax  Litigation.  Subject  to the  balance  of this
Section 5.4(g),  U S WEST and New U S WEST jointly shall conduct all Proceedings
relating  to  Adjustments  of the  MediaOne  Group  and the  New U S WEST  Group
allocated  under this Agreement in connection with a Combined  Return.  U S WEST
shall have the ability to control the conduct of such  Proceedings  with respect
to issues relating to an Adjustment for which the MediaOne Group would be liable
for more  than 50% of the  proposed  Tax  Liability  (as  allocated  under  this
Agreement) attributable to such Adjustment.  New U S WEST shall have the ability
to control the conduct of such Proceedings with respect to issues relating to an
Adjustment for which the New U S WEST Group would be liable for more than 50% of
the proposed Tax Liability (as allocated under this  Agreement)  attributable to
such  Adjustment.  The party with the ability to control the conduct of all or a
portion of the Proceedings pursuant to this Section 5.4(g) shall consult in good
faith with the other party,  which other party shall be entitled to  participate
in all  conferences,  meetings,  and other matters  related to the resolution of
such Proceedings.

                  5.5 Separate Return Matters.  The New U S WEST Group and the
MediaOne  Group  will  be   responsible   for  and  manage  their respective
Separate Return Proceedings.

                  5.6 Payment of Costs. All costs incurred,  whether external or
internal  (such  as  in-house  tax  and  legal  department  salaries  and  other
personnel),  with  respect  to a  Proceeding  shall be borne by the  party  with
respect to which the costs  relate.  All other costs  relating to Tax Returns or
Proceedings not otherwise  provided for in this Agreement shall be allocated 50%
to the New U S WEST Group and 50% to the MediaOne Group.

all of which shall constitute one and the same original.

Agreement  nor any of the rights,  interest or  obligations  hereunder  shall be
assigned by any of the parties hereto  without the prior written  consent of the

court of competent jurisdiction may enforce such restriction













to the maximum  extent  permitted  by law,  and each party  hereby  consents and
agrees that such scope may be judicially modified  accordingly in any proceeding
brought to enforce such restriction.

only upon the occurrence of the Separation.


                  IN WITNESS  WHEREOF,  each of the  Parties has caused this Tax
Sharing  Agreement to be executed on its behalf by its officers  thereunto  duly
authorized, all as of the day and year first written above.
