Periods and any Straddle Period shall be allocated to the New U S WEST Group 
and the MediaOne Group in accordance with the Code and Treasury Regulations 
(and any applicable state, local and foreign laws or regulations).  U S WEST

the Separation Date, or shall jointly estimate such amounts which are not 
determinable as of the Separation Date, and hereby agree to compute all Tax 
Liabilities for Taxable Years ending after the Separation Date consistently

non-federal Taxes by or to a Tax Authority as taxable or deductible, as the

U S WEST, as agent for U S WEST, will be responsible for the filing of the 
Combined Returns for the Taxable Years ended December 31, 1997 and ending 
December 31, 1998 and, at the request of U S WEST, shall use its best efforts 
to file any 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 

                                      10



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 

                                      11



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 

                                      12



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.

                                      13



               (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 

                                      14



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.

                                      15



          (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.

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

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.
