                  AGREEMENT AND PLAN OF MERGER, dated as of May 16, 1999,
between U S WEST, Inc., a Delaware corporation ("U S WEST"), and Global Crossing
Ltd., a Bermuda company ("Global").

                              W I T N E S S E T H


                  WHEREAS, the Boards of Directors of U S WEST and Global have
each determined that it is in the best interests of their respective
stockholders that U S WEST and Global combine their businesses and enter into
this Agreement.

                  WHEREAS, the Boards of Directors of U S WEST and Global have
each determined that the mergers and the other transactions contemplated hereby
are consistent with, and in furtherance of, their respective business strategies
and goals and have each approved the mergers contemplated hereby.


                  WHEREAS, for U.S. federal income tax purposes, it is intended
that the transactions to be effected pursuant to this Agreement shall constitute
a tax-free exchange or series of exchanges.


                  WHEREAS, U S WEST has entered into a Tender Offer and Purchase
Agreement dated as of the date hereof pursuant to which U S WEST will commence a
tender offer (the "U S WEST Tender Offer") for up to 39,259,305 shares of common
stock, par value $0.01 per share of Global ("Global Common Stock"), at a net
price per share in cash of $62.75, subject to the terms and conditions thereof.


                  WHEREAS, the parties hereto intend that the transactions
contemplated hereby shall be accounted for using the purchase method of
accounting with U S WEST as the acquiror.


                  NOW, THEREFORE, in consideration of the foregoing and the
mutual covenants and agreements herein contained, and intending to be legally
bound hereby, the parties hereto hereby agree as follows:


                                   ARTICLE I

                                  THE MERGERS

          Section 1.1 Formation of Subsidiaries; The Mergers. (a) Promptly
following the date hereof, U S WEST and Global will form a corporation under
Delaware Law ("Parent"). Parent will initially be owned equally by U S WEST and
Global. The Certificate of Incorporation of Parent will provide that Parent will
have authority to issue two classes of common stock as follows: subject to
Section 7.24, (i) one class of common stock that will reflect the local service
provider business of Parent, including all of U S WEST's assets, liabilities and
business operations (other than its data, wireless and internet yellow pages
directory assets and liabilities) plus the local exchange assets, liabilities
and 

 
business operations of Frontier Corporation, a New York corporation ("Frontier")
(the "Parent Class A Common Stock"), and (ii) a second class of common stock
that will reflect the global service provider business of Parent, including all
of the assets, liabilities, and business operations of Global and Frontier
(other than Frontier's local exchange assets, liabilities and business
operations) plus U S WEST's data, wireless and internet yellow pages assets,
liabilities and business operations (the "Parent Class B Common Stock"). The
terms of the Parent Class A Common Stock and Parent Class B Common Stock will be
as set forth in Exhibit A. The Certificate of Incorporation of Parent will
contain such other provisions as are customary for public companies including a
classified Board of Directors. Parent will also adopt an appropriate shareholder
rights agreement. Promptly following the incorporation of Parent, U S WEST and
Global will cause Parent to form (i) a wholly-owned subsidiary under Delaware
Law ("U S WEST Merger Sub"), and (ii) if necessary to consummate the transaction
contemplated by the Election, as defined herein, a wholly-owned subsidiary under
Delaware Law or under the laws of such other jurisdiction as necessary to
consummate the transaction contemplated by the Election ("Global Merger Sub").
Parent, U S WEST Merger Sub and Global Merger Sub will be formed solely to
facilitate the Mergers (as defined below) and will conduct no business or
activity prior to the Effective Time other than in connection with the Mergers.
U S WEST and Global will (i) cause Parent, U S WEST Merger Sub and Global Merger
Sub to execute and deliver a joinder to this Agreement pursuant to Section 251
of Delaware Law, (ii) execute a formal written consent under Section 228 of
Delaware Law as all of the stockholders of Parent, approving the execution,
delivery and performance of this Agreement by Parent, (iii) cause Parent to
execute a formal written consent under Section 228 of Delaware Law as the sole
stockholder of U S WEST Merger Sub, approving the execution, delivery and
performance of this Agreement by U S WEST Merger Sub, and (iv) cause Parent to
execute a formal written consent under Bermuda Law (or similar required
documentation under the relevant jurisdiction) as the sole stockholder of Global
Merger Sub, approving the execution, delivery and performance of this Agreement
by Global Merger Sub.

                  (b) At the Effective Time, (i) U S WEST Merger Sub shall be
merged with and into U S WEST in accordance with Delaware Law, whereupon the
separate existence of U S WEST Merger Sub shall cease, and U S WEST shall be the
surviving corporation (the "U S WEST Merger"), and (ii) at Global's reasonable
election (the "Election") either (A) Global shall "discontinue" under the laws
of Bermuda and continue in, and be subject to, the laws of the United States or
any other jurisdiction and Global Merger Sub shall immediately thereafter be
merged into Global with Global as the surviving corporation, (B) Global shall
enter into a scheme of arrangement under the laws of Bermuda pursuant to which
the shares of Global shall be exchanged for shares of Parent, or (C) Global
Merger Sub shall be amalgamated with and into Global in accordance with Bermuda
Law, whereupon the separate existence of Global Merger Sub shall cease, and
Global shall continue in the form of the amalgamated company (any of the
transactions described in the immediately preceding clauses (A), (B) or (C), the
"Global Merger" and together with the U S WEST Merger, the "Mergers"); provided
in any case that the Election shall not cause a failure to satisfy the
conditions contained in Sections 8.2(d) or 8.3(d), and provided further that if
the Election would cause a failure to satisfy the conditions contained in
Section 8.2(d) or 8.3(d), the parties agree to use commercially reasonable
efforts to restructure the Mergers or take other steps in accordance with this
Section 1.1(b) to the extent such 

                                      -2-

 
restructuring or other steps would allow the conditions contained in Sections
8.2(d) and 8.3(d) to be satisfied. U S WEST and Global are sometimes
collectively referred to herein as the "Surviving Corporations". U S WEST Merger
Sub and Global Merger Sub are sometimes collectively referred to herein as the
"Merged Corporations". U S WEST and Global, as well as Parent, U S WEST Merger
Sub, Global Merger Sub and any other Person which may become a party to this
Agreement after the date of this Agreement, are herein referred to collectively
as the "Parties" and each individually as a "Party."

          Section 1.2 Effective Time. As promptly as practicable after the
satisfaction or waiver of the conditions set forth in Article VIII hereof and
the consummation of the Closing referred to in Section 7.3(a) hereof, the
Parties shall cause the Mergers to be consummated by (i) filing a Certificate of
Merger (the "Delaware Certificate") with the Secretary of State of the State of
Delaware with respect to the U S WEST Merger, in such form as is required by,
and executed in accordance with, the relevant provisions of Delaware Law, and
(ii) taking such actions as may be necessary to consummate the transaction
contemplated by the Election (the "Election Transaction Filings"). The effective
time of the U S WEST Merger specified in the Delaware Certificate shall also be
the effective time of the Global Merger specified in the applicable Election
Transaction Filing. The term "Effective Time" shall mean the effective time of
the U S WEST Merger and the Global Merger.

          Section 1.3 Effect of the Mergers. At the Effective Time, the effect
of the U S WEST Merger and the Global Merger shall be as provided in the
applicable provisions of Delaware Law and the laws of the relevant jurisdiction
or jurisdictions of Global, respectively. Without limiting the generality of the
foregoing, and subject thereto, at the Effective Time (i) all the property,
rights, privileges, powers and franchises of U S WEST and U S WEST Merger Sub
shall continue with, or vest in, as the case may be, U S WEST as the Surviving
Corporation in the U S WEST Merger, and all debts, liabilities and duties of U S
WEST and U S WEST Merger Sub shall continue to be, or become, as the case may
be, the debts, liabilities and duties of U S WEST as the Surviving Corporation
in the U S WEST Merger and (ii) all the property, rights, privileges, powers and
franchises of Global and Global Merger Sub shall continue with, or vest in, as
the case may be, Global as the Surviving Corporation in the Global Merger, and
all debts, liabilities and duties of Global and Global Merger Sub shall continue
to be, or become, as the case may be, the debts, liabilities and duties of
Global as the Surviving Corporation in the Global Merger. As of the Effective
Time, the Surviving Corporations shall be direct wholly-owned subsidiaries of
Parent.

          Section 1.4 Subsequent Actions. If, at any time after the Effective
Time, any Surviving Corporation shall consider or be advised that any deeds,
bills of sale, assignments, assurances or any other actions or things are
necessary or desirable to continue in, vest, perfect or confirm of record or
otherwise in such Surviving Corporation their respective right, title or
interest in, to or under any of the rights, properties, privileges, franchises
or assets of either of its constituent corporations acquired or to be acquired
by such Surviving Corporation as a result of, or in connection with, the Mergers
or otherwise to carry out this Agreement, then the officers and directors of
such Surviving Corporation shall be directed and authorized to execute and
deliver, in the name and on behalf of either of such constituent corporations,
all such deeds, bills of sale, assignments and assurances and to take and do, in
the name and on behalf of each of such corporations or otherwise, all such other
actions and things as may be necessary or desirable to 

                                      -3-

 
vest, perfect or confirm any and all right, title and interest in, to and under
such rights, properties, privileges, franchises or assets in such Surviving
Corporation or otherwise to carry out this Agreement.

                                  ARTICLE II

                    EFFECT OF MERGERS ON STOCK AND OPTIONS

          Section 2.1   Conversion of Securities.  The manner and basis of
converting the shares of common stock of Global and Global Merger Sub and U S
WEST and U S WEST Merger Sub, as well as options, warrants and other rights to
purchase or otherwise acquire shares of common stock of Global or shares of
common stock of U S WEST, at the Effective Time, by virtue of the Mergers and
without any action on the part of any of the Parties or the holder of any of
such securities, shall be as hereinafter set forth in this Article II.


          Section 2.2 Conversion. (a) Each share of Global Common Stock and each
share of common stock, par value $.01 per share, of U S WEST ("U S WEST Common
Stock") issued and outstanding immediately prior to the Effective Time
(excluding shares of Global Common Stock held in the treasury of Global or owned
by U S WEST or any of its Subsidiaries and shares of U S WEST Common Stock held
in the treasury of U S WEST or owned by Global or any of its Subsidiaries
(collectively, the " Disqualified Shares")), and all rights in respect thereof,
shall at the Effective Time forthwith cease to exist and be converted into and
become exchangeable for a number of shares of Parent Class A Common Stock and a
number of shares of Parent Class B Common Stock determined as provided in this
Section 2.2.

          (b) Each option, warrant and other right issued and outstanding
immediately prior to the Effective Time to purchase or otherwise acquire Global
Common Stock (each a "Global Right") or U S WEST Common Stock (each a "U S WEST
Right") (other than Global Rights owned by U S WEST or any of its Subsidiaries
and U S WEST Rights owned by Global or any of its Subsidiaries (collectively,
the "Disqualified Rights")) shall at the Effective Time no longer be options,
warrants or rights to purchase or otherwise acquire Global Common Stock or U S
WEST Common Stock, as applicable, and shall become options, warrants or rights,
as applicable, to purchase or otherwise acquire a number of shares of Parent
Class A Common Stock and Parent Class B Common Stock, determined as provided in
this Section 2.2 on the same terms and conditions that would have applied to the
purchase or other acquisition of Global Common Stock or U S WEST Common Stock,
as applicable; provided, that the exercise price of any such option, warrant or
right shall be adjusted as provided in Section 2.2(g). Prior to the Effective
Time, the compensation committee of both U S WEST and Global will review the
Global Rights and U S WEST Rights, as applicable, with a view to providing
incentives for and retaining employees for Parent. U S WEST and Global shall
take all such steps as may be required to cause consummation of the transactions
contemplated by this Section 2.2(b) and any other disposition of U S WEST and
Global equity securities (including derivative securities) or acquisitions of
Parent equity securities (including derivative securities) in connection with
this Agreement by each individual who (x) is a director or officer of U S WEST
or Global or (y) at

                                      -5-

 
the Effective Time, will become a director or officer of Parent, to be exempt
under Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as
amended, such steps to be taken in accordance with the No-Action Letter dated
January 12, 1999, issued by the SEC to Skadden, Arps, Slate, Meagher & Flom LLP.

                  (c) Each holder of record of Global Common Stock and/or Global
Rights (other than Global Common Stock which is Disqualified Stock and Global
Rights which are Disqualified Rights) immediately prior to the Effective Time
shall be entitled to make a number of elections for shares of Parent Class B
Common Stock and/or Parent Class A Common Stock equal to the sum of the number
of shares of Global Common Stock held by such holder at the Effective Time and
the number of shares of Global Common Stock issuable pursuant to Global Rights
held by such holders at the Effective Time. Each holder of record of U S WEST
Common Stock and/or U S WEST Rights (other than U S WEST Common Stock which is
Disqualified Stock and U S WEST Rights which are Disqualified Rights)
immediately prior to the Effective Time shall be entitled to make a number of
elections for shares of Parent Class B Common Stock and/or Parent Class A Common
Stock equal to the product of the Conversion Ratio (as defined below) multiplied
by the number of shares of U S WEST Common Stock held by such holder at the
Effective Time and the number of shares of U S WEST Common Stock issuable
pursuant to U S WEST Rights held by such holders at the Effective Time. The
"Conversion Ratio" shall be equal to the quotient (rounded to the nearest
1/10,000) of (A) the sum of (i) the fully diluted number of shares of Global
Common Stock outstanding on the date hereof (based on the treasury method of
accounting assuming the price of Global Common Stock at the close of trading on
May 13, 1999), plus (ii) the product of the fully diluted number of shares of
Frontier common stock outstanding (based on the treasury method of accounting
assuming the price of Frontier common stock as of the close of trading on the
day prior to consummation of the transactions contemplated by the Frontier
Merger Agreement) on the date of the closing pursuant to the Frontier Merger
Agreement multiplied by the Exchange Ratio (as defined in the Frontier Merger
Agreement) determined as of the date of such closing, less (iii) 39,259,305
divided by (B) the fully diluted number of shares of U S WEST Common Stock
outstanding on the date hereof (based on the treasury method of accounting
assuming the price of U S WEST Common Stock at the close of trading on May 13,
1999). Each election may be made for Parent Class B Common Stock or Parent Class
A Common Stock. A holder holding both Global Common Stock and Global Rights
and/or U S WEST Common Stock and U S WEST Rights shall have the right to
separately elect with respect to such common stock and rights. Each election
made (or, pursuant to Section 2.4, deemed to be made) for Parent Class B Common
Stock shall be an election for a number of shares of Parent Class B Common Stock
equal to a quotient the numerator of which is the sum of 1 plus the Class B to
Class A Value Ratio (as defined in Section 7.17) and the denominator of which is
the Class B to Class A Value Ratio. Each election made (or, pursuant to Section
2.4 deemed to be made) for Parent Class A Common Stock shall be an election for
a number of shares of Parent Class A Common Stock equal to the sum of 1 plus the
Class B to Class A Value Ratio.

                  (d) If the aggregate number of shares of Parent Class B Common
Stock elected (or deemed to be elected) pursuant to Sections 2.2(c) and 2.4
equals the aggregate number of elections that may be made pursuant to Section
2.2(c) by all holders of Global Common Stock and Global Rights and U S WEST
Common Stock and U S WEST Rights (the "Number of Group Shares") and the
aggregate number of shares of Parent Class A Common 

                                      -6-

 
Stock elected (or deemed to be elected) pursuant to Sections 2.2(c) an 2.4
equals the Number of Group Shares, then (i) the shares of Global Common Stock as
to which each holder of record of Global Common Stock is entitled to make an
election pursuant to Section 2.2(c) shall be converted into and exchangeable
for, and the Global Rights as to which each holder of record of Global Rights is
entitled to make an election pursuant to Section 2.2(c) shall become options,
warrants or rights, as applicable, to purchase or otherwise acquire, the number
of shares of Parent Class B Common Stock and the number of shares of Parent
Class A Common Stock elected (or deemed to be elected) by such holder pursuant
to Sections 2.2(c) and 2.4 and (ii) the shares of U S WEST Common Stock as to
which each holder of record of U S WEST Common Stock is entitled to make an
election pursuant to Section 2.2(c) shall be converted into and exchangeable
for, and the U S WEST Rights as to which each holder of record of U S WEST
Rights is entitled to make an election pursuant to Section 2.2(c) shall become
options, warrants or rights, as applicable, to purchase or otherwise acquire,
the number of shares of Parent Class B Common Stock and the number of shares of
Parent Class A Common Stock elected (or deemed to be elected) by such holder
pursuant to Sections 2.2(c) and 2.4.

                  (e) If the aggregate number of shares of Parent Class B Common
Stock elected (or deemed to be elected) pursuant to Sections 2.2(c) and 2.4
exceeds the Number of Group Shares, then (A) the shares of Global Common Stock
as to which each holder of record of Global Common Stock is entitled to make an
election pursuant to Section 2.2(c) shall be converted into and exchangeable
for, (B) the shares of U S WEST Common Stock as to which each holder of record
of U S WEST Common Stock is entitled to make an election pursuant to Section
2.2(c) shall be converted into and exchangeable for, (C) the Global Rights as to
which each holder of record of Global Rights is entitled to make an election
pursuant to Section 2.2(c) shall become options, warrants or rights, as
applicable, to purchase or otherwise acquire, and (D) the U S WEST Rights as to
which each holder of record of U S WEST Rights is entitled to make an election
pursuant to Section 2.2(c) shall become options, warrants or rights, as
applicable, to purchase or otherwise acquire:

                   (i)    a number of shares of Parent Class B Common Stock 
equal to the product of the number of shares of Parent Class B Common Stock
elected (or deemed to be elected) by such holder pursuant to Sections 2.2(c) and
2.4, multiplied by the quotient of the Number of Group Shares divided by the
aggregate number of shares of Parent Class B Common Stock elected (or deemed to
be elected) pursuant to Sections 2.2(c) and 2.4,

                   (ii)   the number of shares of Parent Class A Common Stock
elected (or deemed to be elected) by such holder pursuant to Sections 2.2(c) and
2.4, and

                  (iii)   a number of shares of Parent Class A Common Stock
equal to the product of the Class B to Class A Value Ratio multiplied by the
difference between the number of shares of Parent Class B Common Stock elected
(or deemed to be elected) by such holder pursuant to Sections 2.2(c) and 2.4 and
the number of shares of Parent Class B Common Stock allocated to such holder
pursuant to clause (i) of this sentence.

                 (f) If the aggregate number of shares of Parent Class A Common
Stock elected (or deemed to be elected) pursuant to Sections 2.2(c) and 2.4
exceeds the Number of 

                                      -7-

 
Group Shares, then (A) the shares of Global Common Stock as to which each holder
of record of Global Common Stock is entitled to make an election pursuant to
Section 2.2(c) shall be converted into and exchangeable for, (B) the shares of U
S WEST Common Stock as to which each holder of record of U S WEST Common Stock
is entitled to make an election pursuant to Section 2.2(c) shall be converted
into and exchangeable for, (C) the Global Rights as to which each holder of
record of Global Rights is entitled to make an election pursuant to Section
2.2(c) shall become options, warrants or rights, as applicable, to purchase or
otherwise acquire, and (D) the U S WEST Rights as to which each holder of record
of U S WEST Rights is entitled to make an election pursuant to Section 2.2(c)
shall become options, warrants or rights, as applicable, to purchase or
otherwise acquire:

                   (i)   a number of shares of Parent Class A Common Stock equal
to the product of the number of shares of Parent Class A Common Stock elected
(or deemed to be elected) by such holder pursuant to Sections 2.2(c) and 2.4,
multiplied by the quotient of the Number of Group Shares divided by the
aggregate number of shares of Parent Class A Common Stock elected (or deemed to
be elected) pursuant to Sections 2.2(c) and 2.4,

                  (ii)   the number of shares of Parent Class B Common Stock
elected (or deemed to be elected) by such holder pursuant to Sections 2.2(c) and
2.4, and


                  (iii)   a number of shares of Parent Class B Common Stock
equal to the product of the quotient of 1 divided by the Class B to Class A
Value Ratio multiplied by the difference between the number of shares of Parent
Class A Common Stock elected (or deemed to be elected) by such holder pursuant
to Sections 2.2(c) and 2.4, and the number of shares of Parent Class A Common
Stock allocated to such holder pursuant to clause (i) of this sentence.

                  (g) Commencing immediately after the Effective Time, each
certificate which, immediately prior to the Effective Time, represented issued
and outstanding shares of Global Common Stock or U S WEST Common Stock shall
evidence ownership of Parent Class A Common Stock and Parent Class B Common
Stock on the basis hereinbefore set forth. Commencing immediately after the
Effective Time, each option, warrant or other right which, immediately prior to
the Effective Time, represented the right to purchase or otherwise acquire
shares of Global Common Stock or U S WEST Common Stock shall evidence the right
to purchase or otherwise acquire shares of Parent Class A Common Stock and
Parent Class B Common Stock on the basis hereinabove set forth and otherwise,
subject to Section 2.6, on the same terms and conditions that would have applied
to the purchase or other acquisition of Global Common Stock or U S WEST Common
Stock, as applicable; provided that the exercise price shall be allocated to the
purchase of Parent Class B Common Stock and Parent Class A Common Stock in
proportion to the Class B to Class A Value Ratio.

                  (h)    For all purposes of this Agreement, unless otherwise
specified, all shares held by employee stock ownership plans or other pension or
deferred compensation plans of Global or U S WEST (i) shall be deemed to be
issued and outstanding, (ii) shall not be deemed to be held in the treasury of
Global or U S WEST respectively, and (iii) shall be subject to the election
rights and procedures described in Sections 2.2(c) and 2.4.

                                      -8-

 
                  (i) Under Bermuda law (or the law of the relevant
jurisdiction) within one month of receiving notice of the meeting of the Global
stockholders which is to consider the Global Merger, a Global stockholder is
entitled to apply to the Bermuda Court (or may be entitled under the laws of the
relevant jurisdiction) for an appraisal of the fair value of his shares. Prior
to the Effective Time, and within one month of the Bermuda Court (or the court
of the relevant jurisdiction) appraising the fair value of such shares, Global
shall cause Frontier to pay to the dissenting stockholder an amount equal to the
value of his shares as appraised by the Bermuda Court (or the court of the
relevant jurisdiction) or alternatively may terminate this Agreement as provided
in Section 9.1(f) hereof. After the Effective Time, where the Bermuda Court (or
the court of the relevant jurisdiction) has appraised the shares of a dissenting
stockholder of Global and the amount paid to such dissenting stockholder in the
Global Merger was less than the amount appraised by the Bermuda Court (or the
court of the relevant jurisdiction), Global, as the Surviving Corporation in the
Global Merger, shall cause Frontier to pay to such stockholder the difference in
value. If any former shareholder of Frontier seeks appraisal of his Global
shares and becomes entitled to be paid the value of his shares, Global shall
cause such cash payment to be made by Frontier.

          Section 2.3  Common Stock of Merged Corporations. (a) At the Effective
Time, each share of common stock, par value $.01 per share, of Global Merger Sub
issued and outstanding immediately prior to the Effective Time, and all rights
in respect thereof, shall, without any action on the part of Parent, be
automatically converted into one share of common stock, par value $.01 per
share, of Global as the Surviving Corporation of the Global Merger.

                 (b)   At the Effective Time, each share of common stock, par
value $.01 per share, of U S WEST Merger Sub issued and outstanding immediately
prior to the Effective Time, and all rights in respect thereof, shall, without
any action on the part of Parent, be automatically converted into one share of
common stock, par value $.01 per share, of U S WEST as the Surviving Corporation
of the U S WEST Merger.

          Section 2.4 Election Procedures; Exchange of Shares. (a) Not later
than thirty (30) days prior to the anticipated Effective Time or such other date
as the Parties may agree in writing, Global shall fix a record date (which may
be the record date for the stockholders meeting contemplated by Section 7.2 if
such meeting date is anticipated to be within ten (10) days of the Effective
Time) for determining which of its stockholders and holders of Global Rights
shall be entitled to elect to make the election contemplated by Section 2.2(c)
and shall cause a Notice and Form of Election (the "Form of Election") together
with a letter of transmittal to be mailed to the holders of record of shares of
Global Common Stock as of such record date and holders of record of Global
Rights as of such record date. Holders of record of both Global Common Stock and
Global Rights shall receive a Form of Election relating to such Global Common
Stock and a separate Form of Election relating to such Global Rights. Global
shall also cause the Form of Election together with a letter of transmittal to
be mailed to each person to whom a share of Global Common Stock or a Global
Right is issued subsequent to such record date. The election contemplated by
Section 2.2(c) shall be made by holders of shares of Global Common Stock and
Global Rights by delivering the Form of Election to the exchange agent mutually
chosen by Global and U S WEST to act as exchange agent hereunder (the "Exchange
Agent"). Such election shall be made in terms of the percentage (in increments
of one percent (1%)) of each holder's elections that such holder seeks to make
for shares of Parent 

                                      -9-

 
Class B Common Stock and/or shares of Parent Class A Common Stock. To be
effective, a Form of Election must be properly completed, signed and submitted
to the Exchange Agent by 5:00 p.m. (New York City time) on the last business day
prior to the Effective Time or such other time and date as the Parties may agree
(the "Election Deadline"), and accompanied by (1) other than in the case of
Global Rights, (x) the certificates as to which the election is being made, or
(y) an appropriate guarantee of delivery of such certificates as set forth in
such Form of Election from a firm which is a member of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.,
or a commercial bank or trust company having an office or correspondent in the
United States; provided, however, that such certificates are in fact delivered
to the Exchange Agent within three (3) NYSE trading days after the date of
execution of such guarantee of delivery (a "Guarantee of Delivery"), and (2) a
properly completed and signed letter of transmittal. Failure to deliver
certificates covered by a Guarantee of Delivery within three (3) New York Stock
Exchange ("NYSE") trading days after the date of execution of such Guarantee of
Delivery shall be deemed to invalidate any otherwise properly made election.
Parent will have the discretion, which it may delegate in whole or in part to
the Exchange Agent, to determine whether Forms of Election have been properly
completed, signed and submitted or revoked and to disregard immaterial defects
in Forms of Election. The good faith decision of Parent (or the Exchange Agent)
in such matters shall be conclusive and binding. Neither Parent nor the Exchange
Agent will be under any obligation to notify any Person of any defect in a Form
of Election submitted to the Exchange Agent. Any Form of Election may be changed
or revoked prior to the Election Deadline. In the event a Form of Election is
revoked prior to the Election Deadline, Parent shall, or shall cause the
Exchange Agent to, if applicable, cause the certificates representing the shares
of the Global Common Stock or Global Rights covered by such Form of Election to
be promptly returned without charge to the Person submitting the Form of
Election upon written request to that effect from such Person. For purposes
hereof, if a holder of Global Common Stock or Global Rights does not submit a
Form of Election which is received by the Exchange Agent prior to the Election
Deadline (including a holder who submits and then revokes his or her Form of
Election and does not resubmit a Form of Election which is timely received by
the Exchange Agent), if a holder of Global Common Stock submits a Form of
Election without the corresponding certificates or a Guarantee of Delivery or if
the Exchange Agent cannot reasonably determine the election preference of a
holder of Global Common Stock or Global Rights submitting a Form of Election,
then such holder shall be deemed to have elected shares of Parent Class B Common
Stock and shares of Parent Class A Common Stock in the same proportion as the
holders of Global Common Stock who actually made (and were not merely deemed to
have made) elections pursuant to Section 2.2(c) and this Section 2.4.

                  (b) Subject to the terms and conditions hereof, Parent shall
cause the Exchange Agent to effect the exchange of Global Common Stock for the
Parent Class B Common Stock and/or Parent Class A Common Stock in accordance
with the provisions of this Article II. From time to time after the Effective
Time, Parent shall deposit, or cause to be deposited, with the Exchange Agent
certificates representing Parent Class A Common Stock and Parent Class B Common
Stock for conversion of Global Common Stock in accordance with the provisions of
Section 2.2 hereof (such certificates, together with any dividends or
distributions with respect thereto, being herein referred to as the "Global
Exchange Fund"). Commencing immediately after the Effective Time and until the
appointment of the Exchange Agent shall be terminated, each holder of a
certificate or certificates theretofore representing Global Common 

                                     -10-

 
Stock may surrender the same to the Exchange Agent, and, after the appointment
of the Exchange Agent shall be terminated, any such holder may surrender any
such certificate to Parent. Such holder shall be entitled upon such surrender to
receive in exchange therefor a certificate or certificates representing the
number of full shares of Parent Class A Common Stock and Parent Class B Common
Stock into which the Global Common Stock theretofore represented by the
certificate or certificates so surrendered shall have been converted in
accordance with the provisions of Sections 2.2 and 2.4 hereof, together with a
cash payment in lieu of fractional shares, if any, in accordance with Section
2.6 hereof, and all such shares of Parent Class A Common Stock and Parent Class
B Common Stock so issued shall be deemed to have been issued at the Effective
Time. Until so surrendered and exchanged, each outstanding certificate which,
prior to the Effective Time, represented issued and outstanding Global Common
Stock shall be deemed for all corporate purposes of Parent, other than the
payment of dividends and other distributions, if any, to evidence ownership of
the number of full shares of Parent Class A Common Stock and Parent Class B
Common Stock into which the Global Common Stock theretofore represented thereby
shall have been converted at the Effective Time. Unless and until any such
certificate theretofore representing Global Common Stock is so surrendered, no
dividend or other distribution, if any, payable to the holders of record of
Parent Class A Common Stock and Parent Class B Common Stock as of any date
subsequent to the Effective Time shall be paid to the holder of such certificate
in respect thereof. Upon the surrender of any such certificate theretofore
representing Global Common Stock, however, the record holder of the certificate
or certificates representing shares of Parent Class A Common Stock and Parent
Class B Common Stock issued in exchange therefor shall receive from the Exchange
Agent, or from Parent, as the case may be, payment of the amount of dividends
and other distributions, if any, which as of any date subsequent to the
Effective Time and until such surrender shall have become payable with respect
to such number of shares of Parent Class A Common Stock and Parent Class B
Common Stock ("Pre-Surrender Global Dividends"). No interest shall be payable
with respect to the payment of Pre-Surrender Global Dividends upon the surrender
of certificates theretofore representing Global Common Stock. After the
appointment of the Exchange Agent shall have been terminated, any holders of
certificates representing Global Common Stock which have not received payment of
Pre-Surrender Global Dividends shall look only to Parent for payment thereof.
Notwithstanding the foregoing provisions of this Section 2.4(b), neither the
Exchange Agent nor any Party shall be liable to a holder of Global Common Stock
for any Parent Class A Common Stock and Parent Class B Common Stock, any
dividends or distributions thereon or any cash payment for fractional shares as
contemplated by Section 2.6 delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law.

                  (c) Not later than thirty (30) days prior to the anticipated
Effective Time or such other date as the Parties may agree in writing, U S WEST
shall fix a record date (which may be the record date for the stockholders'
meeting contemplated by Section 7.2 if such meeting date is anticipated to be
within ten (10) days of the Effective Time) for determining which of its
stockholders and holders of U S WEST Rights shall be entitled to elect to make
the election contemplated by Section 2.2(c) and shall cause a Form of Election
together with a letter of transmittal to be mailed to the holders of record of
shares of U S WEST Common Stock as of such record date and holders of record of
U S WEST Rights as of such record date. Holders of record of both U S WEST
Common Stock and U S WEST Rights shall receive a form of Election relating to

                                     -11-

 
such U S WEST Common Stock and a separate form of Election relating to such U S
WEST Rights. U S WEST shall also cause the Form of Election together with a
letter of transmittal to be mailed to each person to whom a share of U S WEST
Common Stock or a U S WEST Right is issued subsequent to such record date. The
election contemplated by Section 2.2(c) shall be made by holders of shares of U
S WEST Common Stock and U S WEST Rights by delivering the Form of Election to
the Exchange Agent. Such election shall be made in terms of the percentage (in
increments of one percent (1%)) of each holder's elections that such holder
seeks to make for shares of Parent Class B Common Stock and/or shares of Parent
Class A Common Stock. To be effective, a Form of Election must be properly
completed, signed and submitted to the Exchange Agent by 5:00 p.m. (New York
City time) on the Election Deadline, and accompanied by (1) other than in the
case of U S WEST Rights, (x) the certificates as to which the election is being
made, or (y) an appropriate Guarantee of Delivery of such certificates as set
forth in such Form of Election, and (2) a properly completed and signed letter
of transmittal. Failure to deliver certificates covered by a Guarantee of
Delivery within three (3) NYSE trading days after the date of execution of such
Guarantee of Delivery shall be deemed to invalidate any otherwise properly made
election. Parent will have the discretion, which it may delegate in whole or in
part to the Exchange Agent, to determine whether Forms of Election have been
properly completed, signed and submitted or revoked and to disregard immaterial
defects in Forms of Election. The good faith decision of Parent (or the Exchange
Agent) in such matters shall be conclusive and binding. Neither Parent nor the
Exchange Agent will be under any obligation to notify any Person of any defect
in a Form of Election submitted to the Exchange Agent. Any Form of Election may
be changed or revoked prior to the Election Deadline. In the event a Form of
Election is revoked prior to the Election Deadline, Parent shall, or shall cause
the Exchange Agent to, if applicable, cause the certificates representing the
shares of the U S WEST Common Stock or U S WEST Rights covered by such Form of
Election to be promptly returned without charge to the Person submitting the
Form of Election upon written request to that effect from such Person. For
purposes hereof, if a holder of U S WEST Common Stock or U S WEST Rights does
not submit a Form of Election which is received by the Exchange Agent prior to
the Election Deadline (including a holder who submits and then revokes his or
her Form of Election and does not resubmit a Form of Election which is timely
received by the Exchange Agent), if a holder of U S WEST Common Stock submits a
Form of Election without the corresponding certificates or a Guarantee of
Delivery or if the Exchange Agent cannot reasonably determine the election
preference of a holder of U S WEST Common Stock or U S WEST Rights submitting a
Form of Election, then such holder shall be deemed to have elected shares of
Parent Class A Common Stock and shares of Parent Class B Common Stock in the
same proportion as the holders of U S WEST Common Stock who actually made (and
were not merely deemed to have made) elections pursuant to Section 2.2(c), and
this Section 2.4.

                  (d) Subject to the terms and conditions hereof, Parent shall
cause the Exchange Agent to effect the exchange of U S WEST Common Stock for the
Parent Class B Common Stock and Parent Class A Common Stock in accordance with
the provisions of this Article II. From time to time after the Effective Time,
Parent shall deposit, or cause to be deposited, with the Exchange Agent
certificates representing Parent Class A Common Stock and Parent Class B Common
Stock for conversion of U S WEST Common Stock in accordance with the provisions
of Section 2.2 hereof (such certificates, together with any dividends or
distributions with respect thereto, being herein referred to as the "U S WEST
Exchange Fund"). Commencing immediately after the Effective Time and until the
appointment of the Exchange Agent shall be terminated, each holder of a
certificate or certificates theretofore representing 

                                     -12-

 
U S WEST Common Stock may surrender the same to the Exchange Agent, and, after
the appointment of the Exchange Agent shall be terminated, any such holder may
surrender any such certificate to Parent. Such holder shall be entitled upon
such surrender to receive in exchange therefor a certificate or certificates
representing the number of full shares of Parent Class A Common Stock and Parent
Class B Common Stock into which the U S WEST Common Stock theretofore
represented by the certificate or certificates so surrendered shall have been
converted in accordance with the provisions of Sections 2.2 and 2.4 hereof,
together with a cash payment in lieu of fractional shares, if any, in accordance
with Section 2.6 hereof, and all such shares of Parent Class A Common Stock and
Parent Class B Common Stock so issued shall be deemed to have been issued at the
Effective Time. Until so surrendered and exchanged, each outstanding certificate
which, prior to the Effective Time, represented issued and outstanding U S WEST
Common Stock shall be deemed for all corporate purposes of Parent, other than
the payment of dividends and other distributions, if any, to evidence ownership
of the number of full shares of Parent Class A Common Stock and Parent Class B
Common Stock into which the U S WEST Common Stock theretofore represented
thereby shall have been converted at the Effective Time. Unless and until any
such certificate theretofore representing U S WEST Common Stock is so
surrendered, no dividend or other distribution, if any, payable to the holders
of record of Parent Class A Common Stock and Parent Class B Common Stock as of
any date subsequent to the Effective Time shall be paid to the holder of such
certificate in respect thereof. Upon the surrender of any such certificate
theretofore representing U S WEST Common Stock, however, the record holder of
the certificate or certificates representing shares of Parent Class A Common
Stock and Parent Class B Common Stock issued in exchange therefor shall receive
from the Exchange Agent, or from Parent, as the case may be, payment of the
amount of dividends and other distributions, if any, which as of any date
subsequent to the Effective Time and until such surrender shall have become
payable with respect to such number of shares of Parent Class A Common Stock and
Parent Class B Common Stock ("Pre-Surrender U S WEST Dividends"). No interest
shall be payable with respect to the payment of Pre-Surrender U S WEST Dividends
upon the surrender of certificates theretofore representing U S WEST Common
Stock. After the appointment of the Exchange Agent shall have been terminated,
any holders of certificates representing U S WEST Common Stock which have not
received payment of Pre-Surrender Dividends shall look only to Parent for
payment thereof. Notwithstanding the foregoing provisions of this Section
2.4(d), neither the Exchange Agent nor any Party shall be liable to a holder of
U S WEST Common Stock for any Parent Class A Common Stock and Parent Class B
Common Stock, any dividends or distributions thereon or any cash payment for
fractional shares as contemplated by Section 2.6 delivered to a public official
pursuant to any applicable abandoned property, or escheat or similar law.

                  (e) Notwithstanding anything herein to the contrary,
certificates surrendered for exchange by any affiliate of Global or U S WEST
shall not be exchanged until Parent shall have received a signed agreement from
such affiliate as provided in Section 7.14 hereof.

                  (f) Any portion of the Global Exchange Fund and U S WEST
Exchange Fund which remains undistributed for six (6) months after the Effective
Time shall be delivered to Parent, upon demand, and any holders of Global Common
Stock and U S WEST Common Stock who have not theretofore complied with the
provisions of this Article II shall thereafter look only to Parent for
satisfaction of their claims for Parent Class A Common Stock or Parent Class B

                                     -13-

 
Common Stock and any Pre-Surrender Global Dividends or Pre-Surrender U S WEST
Dividends.

          Section 2.5 Transfer Books. (a) The stock transfer books of Global
shall be closed at the Effective Time and no transfer of any Global Common Stock
will thereafter be recorded on any of such stock transfer books. In the event of
a transfer of ownership of Global Common Stock that is not registered in the
stock transfer records of Global at the Effective Time, a certificate or
certificates representing the number of full shares of Parent Class A Common
Stock and Parent Class B Common Stock into which such Global Common Stock shall
have been converted shall be issued to the transferee and a cash payment in the
amount of Pre-Surrender Global Dividends, if any, in accordance with Section
2.4(b) hereof, if the certificate or certificates representing such Global
Common Stock is or are surrendered as provided in Section 2.4 hereof,
accompanied by all documents required to evidence and effect such transfer and
by evidence of payment of any applicable stock transfer tax.

                  (b) The stock transfer books of U S WEST shall be closed at
the Effective Time and no transfer of any U S WEST Common Stock will thereafter
be recorded on any of such stock transfer books. In the event of a transfer of
ownership of U S WEST Common Stock that is not registered in the stock transfer
records of U S WEST at the Effective Time, a certificate or certificates
representing the number of full shares of Parent Class A Common Stock and Parent
Class B Common Stock into which such U S WEST Common Stock shall have been
converted shall be issued to the transferee and a cash payment in the amount of
Pre-Surrender U S WEST Dividends, if any, in accordance with Section 2.4(d)
hereof, if the certificate or certificates representing such U S WEST Common
Stock is or are surrendered as provided in Section 2.4 hereof, accompanied by
all documents required to evidence and effect such transfer and by evidence of
payment of any applicable stock transfer tax.

          Section 2.6 No Fractional Share Certificates. (a) No scrip or
fractional share certificate for Parent Class A Common Stock or Parent Class B
Common Stock will be issued upon the surrender for exchange of certificates
evidencing Global Common Stock or U S West Common Stock or upon exercise of
Global Rights or U S WEST Rights, and an outstanding fractional share interest
will not entitle the owner thereof to vote, to receive dividends or to any
rights of a stockholder of Parent or of a Surviving Corporation with respect to
such fractional share interest.

                  (b) As promptly as practicable following the Effective Time,
the Exchange Agent shall determine the excess of (i) the number of full shares
of Parent Class A Common Stock and Parent Class B Common Stock to be issued and
delivered to the Exchange Agent pursuant to Section 2.4 hereof, over (ii) the
aggregate number of full shares of Parent Class A Common Stock and Parent Class
B Common Stock to be distributed to holders of Global Common Stock and U S WEST
Common Stock pursuant to Section 2.4 hereof (such excess being herein called the
"Excess Shares"). Following the Effective Time, the Exchange Agent, as agent for
the holders of Global Common Stock and U S WEST Common Stock, shall sell the
Excess Shares at then prevailing prices on the NYSE or the Nasdaq National
Market ("Nasdaq"), all in the manner provided in Section 2.6(c).

                                     -14-

 
                  (c) The sale of the Excess Shares by the Exchange Agent shall
be executed on the NYSE or Nasdaq and shall be executed in round lots to the
extent practicable. The Exchange Agent shall use all reasonable efforts to
complete the sale of the Excess Shares as promptly following the Effective Time
as, in the Exchange Agent's reasonable judgment, is practicable consistent with
obtaining the best execution of such sales in light of prevailing market
conditions. Until the net proceeds of such sale or sales have been distributed
to the holders of Global Common Stock and U S WEST Common Stock, the Exchange
Agent will hold such proceeds in trust for the holders of Global Common Stock
and U S WEST Common Stock (the "Common Shares Trust"). The Exchange Agent shall
determine the portion of the Common Shares Trust to which each holder of Global
Common Stock and U S West Common Stock shall be entitled, if any, by multiplying
(i) the amount of the aggregate net proceeds comprising the Common Shares Trust
resulting from the sale of shares of Parent Class B Common Stock by a fraction
the numerator of which is the amount of fractional Parent Class B Common Stock
interests to which such holder of Global Common Stock or U S WEST Common Stock
is entitled (after taking into account all shares of Global Common Stock and/or
U S West Stock, as applicable, held at the Effective Time by such holder) and
the denominator of which is the aggregate amount of fractional Parent Class B
Common Shares interests to which all holders of Global Common Stock and U S West
Common Stock are entitled and (ii) the amount of the aggregate net proceeds
comprising the Common Shares Trust resulting from the sale of shares of Parent
Class A Common Stock by a fraction the numerator of which is the amount of
fractional Parent Class A Common Stock interests to which such holder of Global
Common Stock or U S WEST Common Stock is entitled (after taking into account all
shares of Global Common Stock and/or U S West Stock, as applicable, held at the
Effective Time by such holder) and the denominator of which is the aggregate
amount of fractional Parent Class A Common Shares interests to which all holders
of Global Common Stock and U S West Common Stock are entitled.

                  (d) Notwithstanding the provisions of subsections (b) and (c)
of this Section 2.6, Parent may decide, at its option, exercised prior to the
Effective Time, in lieu of the issuance and sale of Excess Shares and the making
of the payments contemplated in such subsections, that Parent shall pay to the
Exchange Agent an amount sufficient for the Exchange Agent to pay each holder of
Global Common Stock and U S WEST Common Stock the amount such holder would have
received pursuant to Section 2.6(c) assuming that the sales of Parent Class A
Common Stock and Parent Class B Common Stock were made at a price equal to the
average of the closing prices of the Parent Class A Common Stock or Parent Class
B Common Stock, as applicable, on the New York Stock Exchange or on Nasdaq, as
applicable, for the ten consecutive trading days immediately following the
Effective Time and, in such case, all references herein to the cash proceeds of
the sale of the Excess Shares and similar references shall be deemed to mean and
refer to the payments calculated as set forth in this subsection (d). In such
event, Excess Shares shall not be issued or otherwise transferred to the
Exchange Agent pursuant to Section 2.4(b) or 2.4(d) hereof.

                  (e) As soon as practicable after the determination of the
amount of cash, if any, to be paid to holders of Global Common Stock and U S
WEST Common Stock with respect to any fractional share interests, the Exchange
Agent shall make available such amounts, net of any required withholding and net
of fees and expenses, to such holders of Global Common Stock and U S WEST Common
Stock, subject to and in accordance with the terms of Section 2.4 hereof.

                                     -15-

 
                  (f) Following the Effective Time, upon the exercise of any
Global Right or U S WEST Right entitling the holder thereof to purchase a
fractional share of Parent Class A Common Stock or Parent Class B Common Stock,
Parent will, in lieu of issuing a fractional share Certificate therefor, pay to
such holder the value of such fractional interest as determined based on the
closing price on the trading day immediately preceding the date of exercise of a
share of Parent Class B Common Stock or Parent Class A Common Stock, as
applicable, on the New York Stock Exchange, Nasdaq or such other principal
security exchange on which the Parent Class A Common Stock and Parent Class B
Common Stock shall then be trading, or, if not so traded, based on such price as
shall be determined by, or pursuant to authority delegated by, the Board of
Directors of Parent.

          Section 2.7 Certain Adjustments. (a) If between the date hereof and
the Effective Time, the outstanding shares of Global Common Stock shall be
changed into a different number of shares by reason of any reclassification,
recapitalization, split-up, combination or exchange of shares, or any dividend
payable in stock or other securities shall be declared thereon with a record
date within such period, then the Conversion Ratio shall be adjusted accordingly
to provide to the holders of Global Common Stock the same economic effect as
contemplated by this Agreement prior to such reclassification, recapitalization,
split-up, combination, exchange or dividend.

                  (b) If between the date hereof and the Effective Time, the
outstanding shares of U S WEST Common Stock shall be changed into a different
number of shares by reason of any reclassification, recapitalization, split-up,
combination or exchange of shares, or any dividend payable in stock or other
securities shall be declared thereon with a record date within such period, then
the Conversion Ratio shall be adjusted accordingly to provide to the holders of
U S WEST Common Stock the same economic effect as contemplated by this Agreement
prior to such reclassification, recapitalization, split-up, combination,
exchange or dividend.

                                  ARTICLE III

                            [INTENTIONALLY OMITTED]


                                  ARTICLE IV

                   REPRESENTATIONS AND WARRANTIES OF GLOBAL

                  Global hereby represents and warrants as of the date hereof to
U S WEST as follows:

          Section 4.1 Organization and Qualification; Subsidiaries. Global and
each of its Significant Subsidiaries is a corporation duly organized, validly
existing and in good standing under the laws of its jurisdiction of
incorporation or organization. Each of the Global Subsidiaries which is not a
Significant Subsidiary is duly organized, validly existing and in good standing
under the laws of its jurisdiction of incorporation or organization, except for
such failure which, when taken together with all other such failures, would not
reasonably be expected to have a Material Adverse Effect on Global. Each of
Global and its Subsidiaries has the requisite corporate power and authority and
any necessary Permit to own, operate or lease the properties that it purports to
own, operate or lease and to carry on its business as it is now being 

                                     -16-

 
conducted, and is duly qualified as a foreign corporation to do business, and is
in good standing, in each jurisdiction where the character of its properties
owned, operated or leased or the nature of its activities makes such
qualification necessary, except for such failure which, when taken together with
all other such failures, would not reasonably be expected to have a Material
Adverse Effect on Global.

          Section 4.2  Certificate of Incorporation and Byelaws. Global has
heretofore furnished, or otherwise made available, to U S WEST a complete and
correct copy of the Certificate of Incorporation and the Byelaws, each as
amended to the date hereof, of Global and each of its Significant Subsidiaries.
Such Certificates of Incorporation and Byelaws are in full force and effect.
Neither Global nor any of its Significant Subsidiaries is in violation of any of
the provisions of its respective Certificate of Incorporation or, in any
material respect, its Byelaws.

          Section 4.3  Capitalization. (a) The authorized capital stock of
Global consists solely of 600,000,000 shares of Global Common Stock, of which,

22,033,758 shares were held in the treasury of Global, (iii) 33,382,907 shares
were issuable upon the exercise of options outstanding under the Global option
plans listed on Schedule 4.3 hereto, and (iv) (A) 12,500,012 shares were
issuable upon the exercise of warrants expiring August 13, 2003, exercisable at
$9.50 per share of Global Common Stock, and (B) 5,108,358 shares were issuable
upon the exercise of warrants expiring August 13, 2008, exercisable at $9.50 per
share of Global Common Stock (collectively, the "Global Warrants"). Except as
set forth on Schedule 4.3 or in connection with the transactions contemplated by
the Frontier Merger Agreement or, after the date hereof, as permitted by Section
6.2 hereof, (i) since May 13, 1999, no shares of Global Common Stock have been
issued, except upon the exercise of options and warrants described in the
immediately preceding sentence, and (ii) there are no outstanding Global Equity
Rights. For purposes of this Agreement, Global Equity Rights shall mean
subscriptions, options, warrants, calls, commitments, agreements, conversion
rights or other rights of any character (contingent or otherwise) to purchase or
otherwise acquire from Global or any of Global's Subsidiaries at any time, or
upon the happening of any stated event, any shares of the capital stock or other
voting or non-voting securities of Global ("Global Equity Rights"). Schedule 4.3
hereto sets forth a complete and accurate list of all outstanding Global Equity
Rights as of May 13, 1999. Since May 13, 1999, no Global Equity Rights have been
issued except as set forth on Schedule 4.3 or in connection with the
transactions contemplated by the Frontier Merger Agreement or, after the date
hereof, as permitted by Section 6.2 hereof.

          (b)  Except as set forth on Schedule 4.3, or, after the date hereof,
as permitted by Section 6.2 hereof, there are no outstanding obligations of
Global or any of Global's Subsidiaries to repurchase, redeem or otherwise
acquire any shares of capital stock of Global.

          (c)  All of the issued and outstanding shares of Global Common Stock
are validly issued, fully paid and nonassessable.

          (d) Except as disclosed on Schedule 4.1 hereto, all the outstanding
capital stock of each of Global's Significant Subsidiaries which is owned by
Global is duly authorized, validly issued, fully paid and nonassessable, and is
owned by Global free and clear of any liens, security 

                                     -17-

 
interest, pledges, agreements, claims, charges or encumbrances except for any
liens, security interest, pledges, agreements, claims, charges or encumbrances
which are granted to secure indebtedness permitted by Section 6.2. Except as
hereafter issued or entered into in accordance with Section 6.2 hereof, there
are no existing subscriptions, options, warrants, calls, commitments,
agreements, conversion rights or other rights of any character (contingent or
otherwise) to purchase or otherwise acquire from Global or any of Global's
Subsidiaries at any time, or upon the happening of any stated event, any shares
of the capital stock or other voting or non-voting securities of any Global
Subsidiary, whether or not presently issued or outstanding (except for rights of
first refusal to purchase interests in Subsidiaries which are not wholly-owned
by Global), and there are no outstanding obligations of Global or any of
Global's Subsidiaries to repurchase, redeem or otherwise acquire any shares of
capital stock or other voting or non-voting securities of any of Global's
Subsidiaries, other than such as would not, individually or in the aggregate,
have a Material Adverse Effect on Global. Except for (i) its Subsidiaries, (ii)
immaterial amounts of equity securities, (iii) investments of Persons in which
Global has less than a five percent (5%) interest, and (iv) equity interests
disclosed on Schedule 4.3 hereto or hereafter acquired as permitted under
Section 6.2 hereof, Global does not directly or indirectly own any equity
interest in any other Person.

          (e)    No bonds, debentures, notes or other indebtedness of Global
having the right to vote on any matters on which shareholders may vote are
issued or outstanding except for any securities issued after the date hereof in
accordance with Section 6.2.

          Section 4.4 Authority Relative to this Agreement. Global has the
necessary corporate power and authority to enter into this Agreement and,
subject to obtaining any necessary stockholder approval of the Global Merger and
this Agreement, to carry out its obligations hereunder. The execution and
delivery of this Agreement by Global and the consummation by Global of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Global, subject to the approval of this
Agreement by Global's stockholders required by Bermuda Law. This Agreement has
been duly executed and delivered by Global and, assuming the due authorization,
execution and delivery thereof by the other Parties, constitutes a legal, valid
and binding obligation of Global, enforceable against it in accordance with its
terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium
or other laws relating to or affecting the rights and remedies of creditors
generally and to general principles of equity (regardless of whether considered
in a proceeding in equity or at law).

          Section 4.5 No Conflict; Required Filings and Consents. (a) Except as
described in subsection (b) below, the execution and delivery of this Agreement
by Global does not, and the performance of this Agreement by Global will not,
(i) violate or conflict with the Certificate of Incorporation or Byelaws of
Global, (ii) conflict with or violate any law, regulation, court order, judgment
or decree applicable to Global or any of its Significant Subsidiaries or by
which any of their respective property is bound or affected, (iii) violate or
conflict with the Certificate of Incorporation or Byelaws of any of Global's
Subsidiaries, or (iv) result in any breach of or constitute a default (or an
event which with notice or lapse of time or both would become a default) under,
or give to others any rights of termination or cancellation of, or result in the
creation of a lien or encumbrance on any of the properties or assets of Global
or any of its Subsidiaries pursuant to, result in the loss of any material
benefit under, or require 

                                     -18-

 
the consent of any other party to, any contract, instrument, Permit, license or
franchise to which Global or any of its Significant Subsidiaries is a party or
by which Global, any of such Subsidiaries or any of their respective property is
bound or affected, except, in the case of clauses (ii), (iii), and (iv) above,
for conflicts, violations, breaches, defaults, rights, results or consents
which, individually or in the aggregate, would not have a Material Adverse
Effect on Global.

          (b) Except for applicable requirements, if any, of state, District of
Columbia, or foreign regulatory laws and commissions, the Federal Communications
Commission, the Exchange Act, the premerger notification requirements of the HSR
Act, filing and recordation of appropriate Mergers or other documents as
required by Delaware Law and Bermuda Law and any filings required pursuant to
any state securities or "blue sky" laws or the rules of any applicable stock
exchanges, neither Global nor any of its Significant Subsidiaries is required to
submit any notice, report or other filing with any Governmental or Regulatory
Authority in connection with the execution, delivery or performance of this
Agreement. Except as set forth in the immediately preceding sentence, no waiver,
consent, approval or authorization of any Governmental or Regulatory Authority
is required to be obtained by Global or any of its Significant Subsidiaries in
connection with its execution, delivery or performance of this Agreement.

          Section 4.6 SEC Filings; Financial Statements. (a) Global has filed
all forms, reports and documents required to be filed with the Securities and
Exchange Commission (the "SEC") since January 1, 1998, and has heretofore
delivered or made available to U S WEST, in the form filed with the SEC,
together with any amendments thereto, its (i) Annual Report on Form 10-K for the
fiscal year ended December 31, 1998, (ii) all proxy statements relating to
Global's meetings of stockholders (whether annual or special) held since January
1, 1998, (iii) Quarterly Reports on Form 10-Q for the fiscal quarters ended
March 31, June 30 and September 30, 1998, and (iv) all other reports or
registration statements filed by Global with the SEC since January 1, 1998
(collectively, the "Global SEC Reports"). The Global SEC Reports (i) were
prepared substantially in accordance with the requirements of the Securities Act
or the Exchange Act (as defined in Article X hereof), as the case may be, and
the rules and regulations promulgated under each of such respective acts, and
(ii) did not at the time they were filed contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

          (b) The financial statements, including all related notes and
schedules, contained in the Global SEC Reports (or incorporated by reference
therein) fairly present the consolidated financial position of Global and its
Subsidiaries as at the respective dates thereof and the consolidated results of
operations and cash flows of Global and its Subsidiaries for the periods
indicated in accordance with GAAP applied on a consistent basis throughout the
periods involved (except for changes in accounting principles disclosed in the
notes thereto) and subject in the case of interim financial statements to normal
year-end adjustments.

          Section 4.7 Absence of Certain Changes or Events. Except as disclosed
in the Global SEC Reports filed prior to the date hereof and on Schedule 4.7,
since December 31, 1998, and except as permitted by this Agreement or consented
to hereunder, Global and its 

                                     -19-

 
Subsidiaries have not incurred any material liability, except in the ordinary
course of their businesses consistent with their past practices, and there has
not been any change, or any event involving a prospective change, in the
business, financial condition or results of operations of Global or any of its
Subsidiaries which has had, or is reasonably likely to have, a Material Adverse
Effect on Global, and Global and its Subsidiaries have conducted their
respective businesses in the ordinary course consistent with their past
practices.

          Section 4.8 Litigation. There are no claims, actions, suits,
proceedings or investigations pending or, to Global's Knowledge, threatened
against Global or any of its Subsidiaries, or any properties or rights of Global
or any of its Subsidiaries, before any Governmental or Regulatory Authority as
to which there is a reasonable likelihood of an adverse judgment or
determination against Global or any of its Subsidiaries, except for those that
are not, individually or in the aggregate, reasonably likely to have a Material
Adverse Effect on Global or prevent, or materially delay the ability of Global
to consummate the transactions contemplated by this Agreement. With respect to
tax matters, litigation shall not be deemed threatened unless a tax authority
has delivered a written notice of deficiency to Global or any of its
Subsidiaries.

          Section 4.9 No Violation of Law; Permits. The business of Global and
its Subsidiaries is not being conducted in violation of any statute, law,
ordinance, regulation, judgment, order or decree of any Governmental or
Regulatory Authority (including, without limitation, any stock exchange or other
self-regulatory body) ("Legal Requirements"), or in violation of any permits,
franchises, licenses, privileges, immunities, approvals, certificates, orders,
authorizations or consents that are granted by any Governmental or Regulatory
Authority (including, without limitation, any stock exchange or other
self-regulatory body) ("Permits"), except for possible violations none of which,
individually or in the aggregate, would reasonably be expected to have a
Material Adverse Effect on Global. Except as disclosed in Global SEC Reports and
as set forth on Schedule 4.9 hereto, no investigation, review or proceeding by
any Governmental or Regulatory Authority (including, without limitation, any
stock exchange or other self-regulatory body) with respect to Global or its
Subsidiaries in relation to any alleged violation of law or regulation is
pending or, to Global's Knowledge, threatened, nor has any Governmental or
Regulatory Authority (including, without limitation, any stock exchange or other
self-regulatory body) indicated an intention to conduct the same, except for
such investigations which, if they resulted in adverse findings, would not
reasonably be expected to have, individually or in the aggregate, a Material
Adverse Effect on Global. Except as set forth in the Global SEC Reports and on
Schedule 4.9 hereto, neither Global nor any of its Subsidiaries is subject to
any cease and desist or other order, judgment, injunction or decree issued by,
or is a party to any written agreement, consent agreement or memorandum of
understanding with, or is a party to any commitment letter or similar
undertaking to, or is subject to any order or directive by, or has adopted any

is considering issuing or requesting any of the foregoing. None of the
representations and warranties made in this Section 4.9 are being made with
respect to Environmental Laws.

          Section 4.10 Joint Proxy Statement. None of the information supplied

          Section 4.11 Employee Matters; ERISA.  Except as set forth on Schedule
4.11:


          (a) Schedule 4.11 contains a true and complete list of all employee
benefit plans covering present or former employees or directors of Global and of
each of its Subsidiaries or their beneficiaries, or providing benefits to such
persons in respect of services provided to any such entity, or with respect to
which Global or any of its Subsidiaries has, or has had, an obligation to
contribute or any other liability, including, but not limited to, any employee
benefit plans within the meaning of Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), any deferred compensation,
bonus, stock option, restricted stock, incentive, profit sharing, retirement,
savings, medical, health, life insurance, disability, sick leave, cafeteria or
flexible spending, vacation, unemployment compensation, severance or change in
control agreements, arrangements, programs, policies or plans and any other
benefit arrangements or payroll practice (collectively, the "Global Benefit
Plans"), whether funded or unfunded, insured or uninsured, written or unwritten.

          (b) All contributions and other payments required to be made by Global
or any of its Subsidiaries to or under any Global Benefit Plan (or to any person
pursuant to the terms thereof) have been made or the amount of such payment or
contribution obligation has been reflected in the Global Financial Statements.

          (c) Each of the Global Benefit Plans intended to be "qualified" within
the meaning of Section 401(a) of the Code has been determined by the Internal
Revenue Service (the "IRS") to be so qualified, and, to Global's Knowledge, no
circumstances exist that could reasonably be expected by Global to adversely
affect such qualification. Global is in compliance in all material respects
with, and each of the Global Benefit Plans complies in form with, and is and has
been operated in all material respects in compliance with, all applicable Legal
Requirements, including, without limitation, ERISA and the Code. No assets of
Global or any of its Subsidiaries are subject to liens arising under ERISA or
the Code on account of any Global 

                                     -21-

 
Benefit Plan, neither Global nor any of its Subsidiaries has been required to
provide any security under Sections 401(a)(29) or 412(f) of the Code, or under
Section 307 of ERISA, and no event has occurred that could give rise to any such
lien or a requirement to provide such security.

          (d) With respect to the Global Benefit Plans, individually and in the
aggregate, no event has occurred and, to Global's Knowledge, there does not now
exist any condition or set of circumstances, that could subject Global or any of
its Subsidiaries to any material liability arising under the Code, ERISA or any
other applicable Legal Requirements (including, without limitation, any
liability to any such plan or the Pension Benefit Guaranty Corporation (the
"PBGC")), or under any indemnity agreement to which Global or any of its
Subsidiaries is a party, excluding liability for benefit claims and funding
obligations payable in the ordinary course. No Global Benefit Plan subject to
Title IV of ERISA has terminated, nor has a "reportable event" (within the
meaning of Section 4043 of ERISA) occurred with respect to any such plan (other
than such events with respect to which the reporting requirement has been waived
by regulation).

          (e) None of the Global Benefit Plans that are "welfare plans" within
the meaning of Section 3(1) of ERISA (i) provide for any post-employment or
retiree benefits other than continuation coverage required to be provided under
Section 4980B of the Code, Part 6 of Title I of ERISA, or applicable state law,
or (ii) has provided any disqualified benefit, within the meaning of Section
4976 of the Code, with respect to which an excise tax has been, or could be,
imposed.

          (f) Global has made available to U S WEST a true and correct copy of
each current or last, in the case where there is no current, expired, collective
bargaining agreement to which Global or any of its Subsidiaries is a party or
under which Global or any of its Subsidiaries has obligations and copies of the
following documents with respect to each Global Benefit Plan, where applicable;
(i) all plan documents governing such plan and the most recent summary plan
description furnished to employees, (ii) the three (3) most recent annual
reports filed with the IRS, (Form 5500-series), including all schedules and
attachments thereto, (iii) each related trust agreement or other funding
arrangement (including all amendments to each such agreement), (iv) the most
recent determination of the IRS with respect to the qualified status of such
Global Benefit Plan, and any currently-pending application for such a letter,
(v) the most recent actuarial report or valuation, and (vi) written descriptions
of unwritten Global Benefit Plans.

          (g) Except as set forth on Schedule 4.11 hereto as made available to U
S WEST prior to the date hereof, (i) the consummation or announcement of any
transaction contemplated by this Agreement will not (either alone or upon the
occurrence of any additional or further acts or events) result in any (A)
payment (whether of severance pay or otherwise) becoming due from Global or any
of its Subsidiaries to any officer, employee, former employee or director
thereof or to the trustee under any "rabbi trust" or similar arrangement, (B)
benefit under any Global Benefit Plan being established or becoming accelerated,
vested or payable, or (C) "reportable event" (as defined in Section 4043 of
ERISA) with respect to a Global Benefit Plan subject to Title IV of ERISA, and
(ii) neither Global nor any of its Subsidiaries is a party to (A) any
management, employment, deferred compensation, severance (including any payment,
right or benefit resulting from a change in control), bonus or other contract
for personal services with any current or former officer, director or employee
(whether or not characterized as a plan for 

                                     -22-

 
purposes of ERISA), (B) any consulting contract with any person who prior to
entering into such contract was a director or officer of Global or any of its
Subsidiaries, or (C) any plan, agreement, arrangement or understanding similar
to any of the items described in clause (ii)(A) or (B) of this sentence.

          (h) The consummation or announcement of any transaction contemplated
by this Agreement will not (either alone or upon the occurrence of any
additional or further acts or events) result in the disqualification of any of
the Global Benefit Plans intended to be qualified under, result in a prohibited
transaction or breach of fiduciary duty under, or otherwise violate, ERISA or
the Code.

          (i) Neither Global nor any of its Subsidiaries nor any of their
directors, officers, employees or agents, nor any "party in interest" or
"disqualified person", as such terms are defined in Section 3 of ERISA and
Section 4975 of the Code, with respect to any Global Benefit Plan, has engaged
in or been a party to any "prohibited transaction", as such term is defined in
Section 4975 of the Code or Section 406 of ERISA which is not otherwise exempt,
which could result in the imposition of either a penalty assessed pursuant to
Section 502(i) of ERISA or a tax imposed by Section 4975 of the Code upon Global
or its Subsidiaries, or which could constitute a breach of fiduciary duty which
could result in liability on the part of Global or any of its Subsidiaries.

          (j) No Global Benefit Plan has incurred any "accumulated funding
deficiency" (as defined in Section 412 of the Code or Part 3 of Title I of
ERISA), whether or not waived. Neither Global nor any of its Subsidiaries has
incurred, and none of such entities reasonably expects to incur, any material
liability to the PBGC with respect to any Global Benefit Plan. Neither Global
nor any of its Subsidiaries is a party to, contributes to, or is required to
contribute to, and neither has incurred or reasonably expects to incur, any
withdrawal liability with respect to, any "multiemployer plan" (as defined in
Section 3(37) of ERISA). No Global Benefit Plan is a "multiple employer plan",
within the meaning of the Code or ERISA.

          Section 4.12 Labor Matters.  Neither Global nor any of its
Subsidiaries is the subject of nor is there pending or threatened, to Global's
Knowledge, any material proceeding asserting that it or any of its Subsidiaries
has committed an unfair labor practice or seeking to compel it to bargain with
any labor union or labor organization, except in each case as would not,
individually or in the aggregate, be reasonably likely to have a Material
Adverse Effect on Global.

          Section 4.13 Environmental Matters. Except for such matters that,
individually or in the aggregate, are not reasonably likely to have a Material
Adverse Effect on Global, or would not otherwise require disclosure pursuant to
the Securities Act, (i) each of Global and its Subsidiaries has complied and is
in compliance with all applicable Environmental Laws (as defined below); (ii)
the properties currently owned or operated by it or any of its Subsidiaries
(including soils, groundwater, surface water, buildings or other structures) are
not contaminated with any Hazardous Substances (as defined below); (iii)
Hazardous Substances were not present, disposed, released or otherwise deposited
on, under, at or from the properties formerly owned or operated by it or any of
its Subsidiaries during the period of ownership or operation by it or any of its
Subsidiaries; (iv) neither it nor any of its Subsidiaries is subject to

                                     -23-

 
liability for any Hazardous Substance disposal or contamination on any third
party property; (v) neither it nor any of its Subsidiaries has been associated
with any release or threat of release of any Hazardous Substance; (vi) neither
it nor any of its Subsidiaries has received any notice, demand, threat, letter,
claim or request for information alleging that it or any of its Subsidiaries may
be in violation of or liable under any Environmental Law (including any claims
relating to electromagnetic fields or microwave transmissions); (vii) neither it
nor any of its Subsidiaries is subject to any orders, decrees, injunctions or
other arrangements with any Governmental or Regulatory Entity or is subject to
any indemnity or other agreement with any third party relating to liability
under any Environmental Law or relating to Hazardous Substances; and (viii)
there are no circumstances or conditions involving it or any of its Subsidiaries
that could reasonably be expected to result in any claims, liability,
investigations, costs or restrictions on the ownership, use, or transfer of any
of its properties pursuant to any Environmental Law.

              As used herein and in Section 5.13, the term "Environmental Law"
means any federal, state, local, foreign or other law (including common law),
statutes, ordinances or codes relating to: (A) the protection, investigation or
restoration of the environment, health, safety or natural resources, (B) the

Chase Securities, Inc., the arrangements with which have been disclosed to U S

banking or other fee or commission in connection with the transactions
contemplated by this Agreement based upon arrangements made by or on behalf of

                                     -24-

 
          Section 4.17 Tax Matters. Except as set forth on Schedule 4.17
attached hereto and except to the extent that the failure of the following
representations to be true would not have a Material Adverse Effect on Global:

          (a)    All Tax Returns required to be filed by Global or its
Subsidiaries on or prior to the Effective Time have been or will be timely filed
with the appropriate Governmental or Regulatory Authorities and are or will be
correct in all material respects, and all material taxes due by Global or its
Subsidiaries on or prior to the Effective Time have been or will be timely paid;

          (b)    All unpaid Taxes in respect of Global or its Subsidiaries with
respect to taxable periods ending on or prior to the Effective Time or with
respect to taxable periods that begin before the Effective Time and end after

such period ending at the Effective Time, have been or will be adequately
reflected as a liability on the books of Global or its Subsidiaries on or prior
to the Effective Time;

          (c)    There are no liens (except for statutory liens for current
Taxes not yet due and payable) against any domestic or foreign assets of Global
or any of its Subsidiaries resulting from any unpaid Taxes;

          (d)    No audit or other proceeding with respect to Taxes due from

all right, title and interest in, or a valid and binding license to use, all
Intellectual Property (as defined below) that is individually or in the
aggregate material to the conduct of the businesses of Global and its
Subsidiaries taken as a whole ("Global Intellectual Property"). Neither Global
nor any Subsidiary of Global is or is alleged to be in default (or with the
giving of notice or lapse of time or both, would be in default) in any material
respect under any license to use Global Intellectual Property, such Intellectual
Property is not being infringed by any third party, and neither Global nor any
Subsidiary of Global is infringing any Intellectual Property of any third party,
except for such defaults and infringements which, individually or in the
aggregate, are not having and could not be reasonably expected to have a
Material Adverse Effect on Global and its Subsidiaries, taken as a whole. Except
as disclosed on Schedule 4.18, there are no (i) circumstances which, with the
giving of notice or the lapse of time, or both, or the failure of Global to act
in a timely fashion, would cause the loss or materially impair the value or
validity of any Global Intellectual Property, or (ii) notices of any material
claim of infringement with respect to any item of Global Intellectual Property,
or notices of any contested patent or other contested item of Global
Intellectual Property except for such circumstances or notices which would not
have a Material Adverse Effect on Global. Global and its Subsidiaries have taken
all reasonable actions necessary to protect, maintain and safeguard the Global
Intellectual Property, including without limitation the Global Intellectual
Property that is confidential in nature, and have executed all 

                                     -25-

 
necessary agreements in connection therewith except where failure to take such
actions or execute such agreements would not have a Material Adverse Effect on
Global. For purposes of this Agreement, "Intellectual Property" means patents
and patent rights, trademarks and trademark rights, trade names and trade name
rights, service marks and service mark rights, copyrights and copyright rights,
trade secret and related non-disclosure rights, and all other proprietary
intellectual property, and all pending applications for and registrations of any
of the foregoing.

          Section 4.19 Insurance. Each of Global and each of its Significant
Subsidiaries is insured with financially responsible insurers in such amounts
and against such risks and losses as are customary for companies conducting the
business as conducted by Global and its Subsidiaries during such time period.
Since January 1, 1998, neither Global nor any of its Subsidiaries has received
notice of cancellation or termination with respect to any material insurance
policy of Global or its Subsidiaries which has not been cured. The insurance
policies of Global and its Subsidiaries are valid and enforceable policies.

          Section 4.20 Ownership of Securities. As of the date hereof, neither
Global nor, to Global's Knowledge, any of its affiliates or associates (as such
terms are defined under the Exchange Act), (a)(i) beneficially owns, directly or
indirectly, or (ii) is party to any agreement, arrangement or understanding for
the purpose of acquiring, holding, voting or disposing of, in each case, shares
of capital stock of U S WEST, which in the aggregate represent ten percent (10%)
or more of the outstanding shares of U S WEST Common Stock (other than shares

retired without consideration pursuant to Section 2.3(a) hereof.

          Section 4.21 Certain Contracts. All material contracts required to be
described in Item 601(b)(10) of Regulation S-K to which Global or its
Subsidiaries is a party or may be bound have been filed as exhibits to, or
incorporated by reference in, Global's Annual Report on Form 10-K for the year
ended December 31, 1998. All contracts, licenses, consents, royalty or other
agreements which are material to Global and its Subsidiaries, taken as a whole,
to which Global or any of its Subsidiaries is a party (the "Global Contracts")
are valid and in full force and effect on the date hereof except to the extent
they have previously expired in accordance with their terms or to the extent
that such invalidity would not have a Material Adverse Effect on Global, and, to
Global's Knowledge, neither Global nor any of its Subsidiaries has violated any
provision of, or committed or failed to perform any act which with or without
notice, lapse of time or both would constitute a default under the provisions
of, any Global Contract, except for defaults which, individually and in the
aggregate, would not reasonably be expected to result in a Material Adverse
Effect on Global.

          Section 4.22 Licenses. Global and each of its Subsidiaries are the
authorized legal holders or otherwise have rights to all material Permits and
licenses and operating rights necessary for the operation of their businesses as
presently operated (collectively, the "Global Licenses"). All Global Licenses
were duly obtained and are validly issued and in full force and effect. Global
is in compliance in all respects with the Communications Act of 1934, as

                                     -26-

 
amended, and the rules, regulations and policies of the FCC and all applicable
Governmental or Regulatory Authorities, except where such failure to comply
would not have a Material Adverse Effect on Global. There is not now pending
and, to Global's Knowledge, there is not threatened in each case as of the date
hereof, any action by or before the FCC or any Governmental or Regulatory
Authority to revoke, suspend, cancel, rescind or modify in any material respect
any of the Global Licenses.

          Section 4.23 Year 2000. Global has (i) initiated a review and
assessment of all areas within its and each of its existing Subsidiaries'
business and operations that could be adversely affected by a failure of any of
its Systems to be Year 2000 Compliant (as defined below), (ii) developed a plan
and timeline for addressing Year 2000 compliance on a timely basis, and (iii) to
date, implemented that plan in accordance with that timetable. Subject to the
qualification contained in the Global SEC Reports, based on the foregoing, to
Global's Knowledge, all Systems that are material to its or any of its
Subsidiaries' business or operations are reasonably expected on a timely basis
to be Year 2000 Compliant.

          Section 4.24 Foreign Corrupt Practices and International Trade
Sanctions. To Global's Knowledge, neither Global, nor any of its Subsidiaries,
nor any of their respective directors, officers, agents, employees or any other
Persons acting on their behalf has, in connection with the operation of their
respective businesses, (i) used any corporate or other funds for unlawful
contributions, payments, gifts or entertainment, or made any unlawful
expenditures relating to political activity to government officials, candidates
or members of political parties or organizations, or established or maintained
any unlawful or unrecorded funds in violation of Section 104 of the Foreign
Corrupt Practices Act of 1977, as amended, or any other similar applicable
foreign, federal or state law, (ii) paid, accepted or received any unlawful
contributions, payments, expenditures or gifts, or (iii) violated or operated in
non-compliance with any export restrictions, anti-boycott regulations, embargo
regulations or other applicable domestic or foreign laws and regulations, except
in each case where there would be no Material Adverse Effect on Global.

March 31, 1999 and (iv) all other reports or registration statements filed by U
S WEST with the SEC since January 1, 1996 (collectively, the "U S WEST SEC

accordance with the requirements of the Securities Act or the Exchange Act, as
the case may be, and the rules and regulations promulgated under each of such
respective acts, and (ii) did not at the time they were filed contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading.

          (b) The financial statements, including all related notes and
schedules, contained in the U S WEST SEC Reports (or incorporated by reference
therein) fairly present the consolidated financial position of U S WEST and its
Subsidiaries as at the respective dates thereof and the consolidated results of
operations and cash flows of U S WEST and its Subsidiaries for the periods
indicated in accordance with GAAP applied on a consistent basis throughout the
periods involved (except for changes in accounting principles disclosed in the

year-end adjustments.

in the U S WEST SEC Reports filed prior to the date hereof and on Schedule 5.7,
since December 31, 1998, and except as permitted by this Agreement or consented

liability, except in the ordinary 

                                     -30-

 
course of their businesses consistent with their past practices, and there has
not been any change, or any event involving a prospective change, in the
business, financial condition or results of operations of U S WEST or any of its
Subsidiaries which has had, or is reasonably likely to have, a Material Adverse
Effect on U S WEST, and U S WEST and its Subsidiaries have conducted their
respective businesses in the ordinary course consistent with their past
practices.

          Section 5.8 Litigation. There are no claims, actions, suits,
proceedings or investigations pending or, to U S WEST's Knowledge, threatened
against U S WEST or any of its Subsidiaries, or any properties or rights of U S
WEST or any of its Subsidiaries, before any Governmental or Regulatory Authority
as to which there is a reasonable likelihood of an adverse judgment or
determination against U S WEST or any of its Subsidiaries, except for those that
are not, individually or in the aggregate, reasonably likely to have a Material
Adverse Effect on U S WEST, or prevent or materially delay the ability of U S
WEST to consummate the transactions contemplated by this Agreement, except as
set forth on Schedule 5.8 hereto. With respect to tax matters, litigation shall
not be deemed threatened unless a tax authority has delivered a written notice
of deficiency to U S WEST or any of its Subsidiaries.

          Section 5.9 No Violation of Law; Permits. The business of U S WEST and
its Subsidiaries is not being conducted in violation of any Legal Requirements
or in violation of any Permits, except for possible violations none of which,
individually or in the aggregate, would reasonably be expected to have a
Material Adverse Effect on U S WEST. Except as disclosed in U S WEST SEC Reports
and as set forth in the U S WEST SEC Reports and on Schedule 5.9 hereto, no
investigation, review or proceeding by any Governmental or Regulatory Authority
(including, without limitation, any stock exchange or other self-regulatory
body) with respect to U S WEST or its Subsidiaries in relation to any alleged
violation of law or regulation is pending or, to U S WEST's Knowledge,
threatened, nor has any Governmental or Regulatory Authority (including, without
limitation, any stock exchange or other self-regulatory body) indicated an
intention to conduct the same, except for such investigations which, if they
resulted in adverse findings, would not reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect on U S WEST Except
as set forth in the U S WEST SEC Reports and on Schedule 5.9 hereto, neither U S
WEST nor any of its Subsidiaries is subject to any cease and desist or other
order, judgment, injunction or decree issued by, or is a party to any written
agreement, consent agreement or memorandum of understanding with, or is a party
to any commitment letter or similar undertaking to, or is subject to any order
or directive by, or has adopted any board resolutions at the request of, any
Governmental or Regulatory Authority that materially restricts the conduct of
its business or which would reasonably be expected to have a Material Adverse
Effect on U S WEST, nor has U S WEST or any of its Subsidiaries been advised
that any Governmental or Regulatory Authority is considering issuing or
requesting any of the foregoing. None of the representations and warranties made
in this Section 5.9 are being made with respect to Environmental Laws.

          Section 5.10 Joint Proxy Statement. None of the information supplied
or to be supplied by or on behalf of U S WEST for inclusion or incorporation by
reference in the Registration Statement will, at the time the Registration
Statement becomes effective under the Securities Act, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. None of the
information supplied 

                                     -31-

 
or to be supplied by or on behalf of U S WEST for inclusion or incorporation by
reference in the Joint Proxy Statement will, at the dates mailed to stockholders
and at the times of the Global stockholders' meeting and the U S WEST
stockholders' meeting, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
are made, not misleading. The Registration Statement and the Joint Proxy
Statement (except for information relating solely to Global) will comply as to
form in all material respects with the provisions of the Securities Act and the
Exchange Act and the rules and regulations promulgated thereunder.

          Section 5.11  Employee Matters; ERISA. Except as set forth on Schedule
5.11:


                  (a) Schedule 5.11 contains a true and complete list of all
employee benefit plans covering present or former employees or directors of U S
WEST and of each of its Subsidiaries or their beneficiaries, or providing
benefits to such persons in respect of services provided to any such entity, or
with respect to which U S WEST or any of its Subsidiaries has, or has had, an
obligation to contribute or any other liability, including, but not limited to,
any employee benefit plans within the meaning of Section 3(3) of ERISA, any
deferred compensation, bonus, stock option, restricted stock, incentive, profit
sharing, retirement, savings, medical, health, life insurance, disability, sick
leave, cafeteria or flexible spending, vacation, unemployment compensation,
severance or change in control agreements, arrangements, programs, policies or
plans and any other benefit arrangements or payroll practice (collectively, the
"U S WEST Benefit Plans"), whether funded or unfunded, insured or uninsured,
written or unwritten.

                  (b) All contributions and other payments required to be
made by U S WEST or any of its Subsidiaries to or under any U S WEST Benefit
Plan (or to any person pursuant to the terms thereof) have been made or the
amount of such payment or contribution obligation has been reflected in the U S
WEST Financial Statements.

                  (c) Each of the U S WEST Benefit Plans intended to be
"qualified" within the meaning of Section 401(a) of the Code has been determined
by the IRS to be so qualified, and, to U S WEST's Knowledge, no circumstances
exist that could reasonably be expected by U S WEST to adversely affect such
qualification. U S WEST is in compliance in all material respects with, and each
of the U S WEST Benefit Plans complies in form with, and is and has been
operated in all material respects in compliance with, all applicable Legal
Requirements, including, without limitation, ERISA and the Code. No assets of U
S WEST or any of its Subsidiaries are subject to liens arising under ERISA or
the Code on account of any U S WEST Benefit Plan, neither U S WEST nor any of
its Subsidiaries has been required to provide any security under Sections
401(a)(29) or 412(f) of the Code, or under Section 307 of ERISA, and no event
has occurred that could give rise to any such lien or a requirement to provide
such security.

                  (d) With respect to the U S WEST Benefit Plans, individually
and in the aggregate, no event has occurred and, to U S WEST's Knowledge, there
does not now exist any condition or set of circumstances, that could subject U S
WEST or any of its Subsidiaries to any material liability arising under the
Code, ERISA or any other applicable Legal Requirements (including, without
limitation, any liability to any such plan or the PBGC), or under any 

                                     -32-

 
indemnity agreement to which U S WEST or any of its Subsidiaries is a party,
excluding liability for benefit claims and funding obligations payable in the
ordinary course. No U S WEST Benefit Plan subject to Title IV of ERISA has
terminated, nor has a "reportable event" (within the meaning of Section 4043 of
ERISA) occurred with respect to any such plan (other than such events with
respect to which the reporting requirement has been waived by regulation).

                  (e) None of the U S WEST Benefit Plans that are "welfare
plans" within the meaning of Section 3(1) of ERISA (i) provides for any post-
employment or retiree benefits other than continuation coverage required to be
provided under Section 4980B of the Code, Part 6 of Title I of ERISA or
applicable state law, or (ii) has provided any disqualified benefit, within the
meaning of Section 4976 of the Code, with respect to which an excise tax has
been, or could be, imposed.

                  (f) U S WEST has made available to Global a true and correct
copy of each current or last, in the case where there is no current, expired
collective bargaining agreement to which U S WEST or any of its Subsidiaries is
a party or under which U S WEST or any of its Subsidiaries has obligations and
copies of the following documents with respect to each U S WEST Benefit Plan,
where applicable, (i) all plan documents governing such plan and the most recent
summary plan description furnished to employees, (ii) the three (3) most recent
annual reports filed with the IRS, (Form 5500-series), including all schedules
and attachments thereto, (iii) each related trust agreement or other funding
arrangement (including all amendments to each such agreement), (iv) the most
recent determination of the IRS with respect to the qualified status of such U S
WEST Benefit Plan, and any currently-pending application for such a letter, (v)
the most recent actuarial report or valuation, and (vi) written description of
unwritten U S WEST Benefit Plans.

                  (g) Except as set forth on Schedule 5.11 hereto as made
available to Global prior to the date hereof, (i) the consummation or
announcement of any transaction contemplated by this Agreement will not (either
alone or upon the occurrence of any additional or further acts or events) result
in any (A) payment (whether of severance pay or otherwise) becoming due from U S
WEST or any of its Subsidiaries to any officer, employee, former employee or
director thereof or to the trustee under any "rabbi trust" or similar
arrangement, (B) benefit under any U S WEST Benefit Plan being established or
becoming accelerated, vested or payable, or (C) "reportable event" (as defined
in Section 4043 of ERISA) with respect to a U S WEST Benefit Plan subject to
Title IV of ERISA, and (ii) neither U S WEST nor any of its Subsidiaries is a
party to (A) any management, employment, deferred compensation, severance
(including any payment, right or benefit resulting from a change in control),
bonus or other contract for personal services with any current or former
officer, director or employee (whether or not characterized as a plan for
purposes of ERISA), (B) any consulting contract with any person who prior to
entering into such contract was a director or officer of U S WEST or any of its
Subsidiaries, or (C) any plan, agreement, arrangement or understanding similar
to any of the items described in clause (ii)(A) or (B) of this sentence.

                  (h)  The consummation or announcement of any transaction
contemplated by this Agreement will not (either alone or upon the occurrence of
any additional or further acts or events) result in the disqualification of any
of the U S WEST Benefit Plans intended to be 

                                     -33-

 
qualified under, result in a prohibited transaction or breach of fiduciary duty
under, or otherwise violate, ERISA or the Code.

          (i) Neither U S WEST nor any of its Subsidiaries nor any of their
directors, officers, employees or agents, nor any "party in interest" or
"disqualified person", as such terms are defined in Section 3 of ERISA and
Section 4975 of the Code, with respect to any U S WEST Benefit Plan, has engaged
in or been a party to any "prohibited transaction", as such term is defined in
Section 4975 of the Code or Section 406 of ERISA, which is not otherwise exempt,
which could result in the imposition of either a penalty assessed pursuant to
Section 502(i) of ERISA or a tax imposed by Section 4975 of the Code upon U S
WEST or its Subsidiaries, or which could constitute a breach of fiduciary duty
which could result in liability on the part of U S WEST or any of its
Subsidiaries.

          (j) No U S WEST Benefit Plan has incurred any "accumulated funding
deficiency" (as defined in Section 412 of the Code or Part 3 of Title I of
ERISA), whether or not waived. Neither U S WEST nor any of its Subsidiaries has
incurred, and none of such entities reasonably expects to incur, any material
liability to the PBGC with respect to any U S WEST Benefit Plan. Neither U S
WEST nor any of its Subsidiaries is a party to, contributes to, or is required
to contribute to, and neither has incurred or reasonably expects to incur, any
withdrawal liability with respect to, any "multiemployer plan" (as defined in
Section 3(37) of ERISA). No U S WEST Benefit Plan is a "multiple employer plan",
within the meaning of the Code or ERISA.

          Section 5.12   Labor Matters. Except as set forth on Schedule 5.12,
neither U S WEST nor any of its Subsidiaries is the subject of any material
proceeding asserting that it or any of its Subsidiaries has committed an unfair
labor practice or seeking to compel it to bargain with any labor union or labor
organization, nor is any such proceeding pending or, to U S WEST's Knowledge,
threatened, except in each case as would not, individually or in the aggregate,
be reasonably likely to have a Material Adverse Effect on U S WEST.

          Section 5.13 Environmental Matters. Except for such matters that,
individually or in the aggregate, are not reasonably likely to have a Material
Adverse Effect on U S WEST, or would not otherwise require disclosure pursuant
to the Securities Act, or are listed on Schedule 5.13 hereto, (i) each of U S
WEST and its Subsidiaries has complied and is in compliance with all applicable
Environmental Laws (as defined below); (ii) the properties currently owned or
operated by it or any of its Subsidiaries (including soils, groundwater, surface
water, buildings or other structures) are not contaminated with any Hazardous
Substances (as defined below); (iii) Hazardous Substances were not present,
disposed, released or otherwise deposited on, under, at or from the properties
formerly owned or operated by it or any of its Subsidiaries during the period of
ownership or operation by it or any of its Subsidiaries; (iv) neither it nor any
of its Subsidiaries is subject to liability for any Hazardous Substance disposal
or contamination on any third party property; (v) neither it nor any of its
Subsidiaries has been associated with any release or threat of release of any
Hazardous Substance; (vi) neither it nor any of its Subsidiaries has received
any notice, demand, threat, letter, claim or request for information alleging
that it or any of its Subsidiaries may be in violation of or liable under any
Environmental Law (including any claims relating to electromagnetic fields or
microwave transmissions); (vii) neither it nor any of its Subsidiaries is
subject to any orders, decrees, 

                                     -34-

 
injunctions or other arrangements with any Governmental or Regulatory Entity or
is subject to any indemnity or other agreement with any third party relating to
liability under any Environmental Law or relating to Hazardous Substances; and
(viii) there are no circumstances or conditions involving it or any of its
Subsidiaries that could reasonably be expected to result in any claims,
liability, investigations, costs or restrictions on the ownership, use, or
transfer of any of its properties pursuant to any Environmental Law.

          Section 5.14 Board Action; Vote Required; U S WEST Rights Plan;
Applicability of Section 203. (a) The Board of Directors of U S WEST has
unanimously determined that the transactions contemplated by this Agreement are
in the best interests of U S WEST and its stockholders and has resolved to
recommend to such stockholders that they vote in favor thereof.

          (b) The approval of this Agreement by a majority of the votes
entitled to be cast by all holders of U S WEST Common Stock is the only vote of
the holders of any class or series of the capital stock of U S WEST required to
approve this Agreement, the Mergers and the other transactions contemplated
hereby.

          (c) The provisions of Section 203 of Delaware Law will not, assuming
the accuracy of the representations contained in Section 4.20 hereof (without
giving effect to the knowledge qualification therein), apply to this Agreement
or any of the transactions contemplated hereby.

          (d) The Board of Directors of U S WEST have taken all actions
necessary to render Article IX of the U S WEST Certificate of Incorporation
inapplicable to the transactions contemplated hereby.

          (e) The Rights Agreement dated as of June 1, 1998 between U S WEST and
State Street Bank and Trust Company has been amended so as to provide that none
or Global or any of its Subsidiaries will be an "Acquiring Person" thereunder.

          Section 5.15  Opinion of Financial Advisor. U S WEST has received
the opinion of Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill
Lynch"), dated the date hereof, to the effect that, as of such date, the
Conversion Ratio is fair from a financial point of view to the holders of U S
WEST Common Stock.

         Section 5.16   Brokers. Except for Merrill Lynch, the arrangements
with which have been disclosed to Global prior to the date hereof, who has been
engaged by U S WEST, no broker, finder or investment banker is entitled to any
brokerage, finder's, investment banking or other fee or commission in connection
with the transactions contemplated by this Agreement based upon arrangements
made by or on behalf of U S WEST or any of its Subsidiaries.

         Section 5.17   Tax Matters. Except as set forth on Schedule 5.17
attached hereto and except to the extent that the failure of the following
representations to be true would not have a Material Adverse Effect on U S WEST:

                 (a)    All Tax Returns required to be filed by U S WEST or
its Subsidiaries on or prior to the Effective Time have been or will be timely
filed with the appropriate 

                                     -35-

 
Governmental or Regulatory Authorities and are or will be correct in all
material respects, and all material taxes due by U S WEST or its Subsidiaries on
or prior to the Effective Time have been, or will be, timely paid;

                  (b)      All unpaid Taxes in respect of U S WEST or its
Subsidiaries with respect to taxable periods ending on or prior to the Effective
Time or with respect to taxable periods that begin before the Effective Time and
end after the Effective Time, to the extent such Taxes are attributable to the
portion of such period ending at the Effective Time, have been or will be
adequately reflected as a liability on the books of U S WEST or its Subsidiaries
on or prior to the Effective Time;

                  (c)      There are no liens (except for statutory liens for
current Taxes not yet due and payable) against any domestic or foreign assets of
U S WEST or any of its Subsidiaries resulting from any unpaid Taxes;

                  (d)      No audit or other proceeding with respect to Taxes
due from U S WEST or any of its Subsidiaries, or any Tax Return of U S WEST or
any of its Subsidiaries is pending, threatened in writing, or being conducted by
any Governmental or Regulatory Authority.

                  (e)      No extension of the statute of limitations on the
assessment of any Taxes has been granted by U S WEST or any of its Subsidiaries
and is currently in effect.

          Section 5.18 Intellectual Property. U S WEST and its Subsidiaries have
all right, title and interest in, or a valid and binding license to use, all
Intellectual Property that is individually or in the aggregate material to the
conduct of the businesses of U S WEST and its Subsidiaries taken as a whole ("U
S WEST Intellectual Property"). Neither U S WEST nor any Subsidiary of U S WEST
is or is alleged to be in default (or with the giving of notice or lapse of time
or both, would be in default) in any material respect under any license to use U
S WEST Intellectual Property, such Intellectual Property is not being infringed
by any third party, and neither U S WEST nor any Subsidiary of U S WEST is
infringing any Intellectual Property of any third party, except for such
defaults and infringements which, individually or in the aggregate, are not
having and could not be reasonably expected to have a Material Adverse Effect on
U S WEST. Except as disclosed in Schedule 5.18, there are no (i) circumstances
which, with the giving of notice or the lapse of time, or both, or the failure
of U S WEST to act in a timely fashion, would cause the loss or materially
impair the value or validity of any U S WEST Intellectual Property, or (ii)
notices of any material claim of infringement with respect to any item of U S
WEST Intellectual Property, or notices of any contested patent or other
contested item of Intellectual Property except for such circumstances or notices
which would not have a Material Adverse Effect on U S WEST. U S WEST and its
Subsidiaries have taken all reasonable actions necessary to protect, maintain
and safeguard the U S WEST Intellectual Property, including without limitation
the U S WEST Intellectual Property that is confidential in nature, and have
executed all necessary agreements in connection therewith except where the
failure to take such actions or execute such agreements would not have a
Material Adverse Effect on U S WEST.

          Section 5.19  Insurance. Except as set forth on Schedule 5.19 hereto,
each of U S WEST and each of its Significant Subsidiaries is insured with
financially responsible 

                                     -37-

 
insurers in such amounts and against such risks and losses as are customary for
companies conducting the business as conducted by U S WEST and its Subsidiaries
during such time period. Except as set forth on such Schedule 5.19, since
January 1, 1998, neither U S WEST nor any of its Subsidiaries has received
notice of cancellation or termination with respect to any material insurance
policy of U S WEST or its Subsidiaries which has not been cured. The insurance
policies of U S WEST and its Subsidiaries are valid and enforceable policies.

          Section 5.20 Ownership of Securities. Except as set forth on Schedule
5.20, as of the date hereof, neither U S WEST nor, to U S WEST's Knowledge, any
of its affiliates or associates (as such terms are defined under the Exchange
Act), beneficially owns, directly or indirectly, or is party to any agreement,
arrangement or understanding for the purpose of acquiring, holding, voting or
disposing of, in each case, shares of capital stock of Global, which in the
aggregate represent ten percent (10%) or more of the outstanding shares of
Global Common Stock (other than shares held by U S WEST Benefit Plans). Except
as set forth on Schedule 5.20 hereto, U S WEST owns no shares of Global Common
Stock described in the parenthetical clause of Section 2.2(a) hereof which would
be canceled and retired without consideration pursuant to Section 2.3(a) hereof.

          Section 5.21 Certain Contracts. All material contracts required to be
described in Item 601(b)(10) of Regulation S-K to which U S WEST or its
Subsidiaries is a party or may be bound have been filed as exhibits to, or
incorporated by reference in, U S WEST's Annual Report on Form 10-K for the year
ended December 31, 1998. All contracts, licenses, consents, royalty or other
agreements which are material to U S WEST and its Subsidiaries, taken as a
whole, to which U S WEST or any of its Subsidiaries is a party (the "U S WEST
Contracts") are valid and in full force and effect on the date hereof except to
the extent they have previously expired in accordance with their terms or to the
extent such invalidity would not have a Material Adverse Effect on U S WEST,
and, to U S WEST's Knowledge, neither U S WEST nor any of its Subsidiaries has
violated any provision of, or committed or failed to perform any act which with
or without notice, lapse of time or both would constitute a default under the
provisions of, any U S WEST Contract, except for defaults which, individually
and in the aggregate, would not reasonably be expected to result in a Material
Adverse Effect on U S WEST.

          Section 5.22 Licenses. U S WEST and each of its Subsidiaries are the
authorized legal holders or otherwise has rights to all material Permits and
licenses and operating rights necessary for the operation of their businesses as
presently operated (collectively, the "U S WEST Licenses"). All U S WEST
Licenses were duly obtained and are validly issued and in full force and effect.
U S WEST is in compliance in all respects with the Communications Act of 1934,
as amended, and the rules, regulations and policies of the FCC and all
applicable Governmental or Regulatory Authorities except for such failure to
comply which would not have a Material Adverse Effect on U S WEST. There is not
now pending and, to U S WEST's Knowledge, there is not threatened, in each case
as of the date hereof, any action by or before the FCC or any Governmental or
Regulatory Authority to revoke, suspend, cancel, rescind or modify in any
material respect any of the U S WEST Licenses.

          Section 5.23 Year 2000. U S WEST has (i) initiated a review and
assessment of all areas within its and each of its existing Subsidiaries'
business and operations that could be 

                                     -37-

 
adversely affected by a failure of any of its Systems to be Year 2000 Compliant
(as defined below), (ii) developed a plan and timeline for addressing Year 2000
compliance on a timely basis, and (iii) to date, implemented that plan in
accordance with that timetable. Subject to the qualification contained in the U
S WEST SEC Reports, based on the foregoing, to U S WEST's Knowledge, all Systems
that are material to its or any of its Subsidiaries' business or operations are
reasonably expected on a timely basis to be Year 2000 Compliant.

          Section 5.24 Foreign Corrupt Practices and International Trade
Sanctions. To U S WEST's Knowledge, neither U S WEST, nor any of its
Subsidiaries, nor any of their respective directors, officers, agents, employees
or any other Persons acting on their behalf has, in connection with the
operation of their respective businesses, (i) used any corporate or other funds
for unlawful contributions, payments, gifts or entertainment, or made any
unlawful expenditures relating to political activity to government officials,
candidates or members of political parties or organizations, or established or
maintained any unlawful or unrecorded funds in violation of Section 104 of the
Foreign Corrupt Practices Act of 1977, as amended, or any other similar
applicable foreign, federal or state law, (ii) paid, accepted or received any
unlawful contributions, payments, expenditures or gifts, or (iii) violated or
operated in noncompliance with any export restrictions, anti-boycott
regulations, embargo regulations or other applicable domestic or foreign laws
and regulations except in each case which would not have a Material Adverse
Effect on U S WEST.

                  (a) From and after the date hereof, Global and U S WEST shall
not nor shall they permit any of their respective Subsidiaries to, nor shall
they authorize or permit any of their respective officers, directors or
employees or any investment banker, financial advisor, attorney, accountants or
other representatives retained by them or any of their respective Subsidiaries
to, directly or indirectly through another person, (i) solicit, initiate or
encourage (including by way of furnishing information), or knowingly take any
other action designed to facilitate, any Alternative Transaction (as hereinafter
defined), or (ii) participate in any discussions regarding any Alternative
Transaction; provided, however, that if, at any time prior to the time the
Global Stockholders' Approval or the U S WEST Stockholders' Approval, as the
case may be, is obtained, the Board of Directors of Global or U S WEST, as the
case may be, determines in good faith, after receipt of advice from outside
counsel, that the failure to provide such information or to participate in such
negotiations or discussions would result in a reasonable likelihood that such
Board of Directors would breach their fiduciary duties to stockholders under
applicable law, Global or U S WEST, as the case may be, may, in response to a
proposal that has been determined by it to be a Global Superior Proposal (as
defined in Section 7.2 hereof) or a U S WEST Superior Proposal (as defined in
Section 7.2 hereof), as the case may be, that was not solicited by it and that
did not otherwise result from a breach of this Section 6.3, and subject to the
Party receiving such proposal giving the other Party at least two business days
written notice of its intention to do so, (x) furnish information with respect
to Global or U S WEST, as the case may be, to any person pursuant to a customary
confidentiality agreement containing terms no less restrictive than the terms of
the Confidentiality Agreement (as defined in Section 7.5(b) hereof), provided
that a copy of all such information is delivered simultaneously to the other
Party, and (y) engage in negotiations regarding such proposal. Each of Global
and U S WEST shall promptly notify the other orally and in writing of any
request for information or of any proposal in connection with an Alternative
Transaction, the material terms and conditions of such request or proposal
(including a copy thereof, if in writing, and all other documentation and any
related correspondence) and the identity of the person making such request or
proposal. 

                                     -42-

 
Each of Global and U S WEST will keep the other Party reasonably
informed of the status and details (including amendments or proposed amendments)
of such request or proposal on a current basis. Each of Global and U S WEST each
immediately cease and terminate any existing solicitation, initiation,
encouragement activity, discussion or negotiation with any persons conducted
heretofore by them or their representatives with respect to the foregoing.

                  (b) Each of Global and U S WEST (i) agrees not to release any
Third Party (as defined in Section 6.3(c)) from, or waive any provision of, or
fail to enforce, any standstill agreement or similar agreement to which it is a
party related to, or which could affect, an Alternative Transaction and agrees
that either Party shall be entitled to enforce the other Party's rights and
remedies under and in connection with such agreements and (ii) acknowledges that
the provisions of clause (i) are an important and integral part of this
Agreement. Nothing contained in this Section 6.3 or in Section 7.2 shall
prohibit either Party (i) from taking and disclosing to its stockholders a
position contemplated by Rule 14e-9 or Rule 14e-2(a) promulgated under the
Exchange Act, or (ii) from making any disclosure to its stockholders if, in the
good faith judgment of the Board of Directors of such Party, after receipt of
advice from outside counsel, failure to disclose would result in a reasonable
likelihood that such Board of Directors would breach its duties to such Party's
stockholders under applicable law.

                  (c) For purposes of this Agreement, "Alternative Transaction"
means a proposal or intended proposal, regarding any of (i) a transaction or
series of transactions pursuant to which any person (or group of persons) other
than a Party and its Subsidiaries (a "Third Party") acquires or would acquire,
directly or indirectly, beneficial ownership (as defined in Rule 13d-3 under the
Exchange Act) of more than twenty percent (20%) of the outstanding shares of
Global or U S WEST, as the case may be, whether from Global or U S WEST or
pursuant to a tender offer or exchange offer or otherwise, (ii) any acquisition
or proposed acquisition of, or business combination with, Global or any of its
Significant Subsidiaries or U S WEST or any of its Significant Subsidiaries, as
the case may be, by a merger or other business combination (including any
so-called "merger-of-equals" and whether or not Global or any of its Significant
Subsidiaries or U S WEST or any of its Significant Subsidiaries, as the case may
be, is the entity surviving any such merger or business combination), or (iii)
any other transaction pursuant to which any third party acquires or would
acquire, directly or indirectly, control of assets (including for this purpose
the outstanding equity securities of Subsidiaries of Global or U S WEST, as the
case may be, and any entity surviving the merger or business combination
including any of them) of Global or any of its Subsidiaries or U S WEST or any
of its Subsidiaries, as the case may be, for consideration equal to twenty
percent (20%) or more of the fair market value of all of the outstanding shares
of Global Common Stock or all of the outstanding shares of U S WEST Common
Stock, as the case may be, on the date of this Agreement.

          Section 6.4 Subsequent Financial Statements. Prior to the Effective
Time, each of Global and U S WEST (a) will consult with the other prior to
making publicly available its financial results for any period and (b) will
consult with the other prior to the filing of, and will timely file with the
SEC, each Annual Report on Form 10-K, Quarterly Report on Form 10-Q and Current
Report on Form 8-K required to be filed by such Party under the Exchange Act and
the rules and regulations promulgated thereunder and will promptly deliver to
the other copies of each such report filed with the SEC. As of their respective
dates, none of such reports 

                                     -43-

 
shall contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The respective audited financial statements and unaudited interim
financial statements of each of Global and U S WEST, as the case may be,
included in such reports will fairly present the financial position of such
Party and its Subsidiaries as at the dates thereof and the results of their
operations and cash flows for the periods then ended in accordance with GAAP
applied on a consistent basis and, subject, in the case of unaudited interim
financial statements, to normal year-end adjustments and any other adjustments
described therein.

          Section 6.5 Control of Operations.  Nothing contained in this
Agreement shall give U S WEST, directly or indirectly, the right to control or
direct Global's operations prior to the Effective Time. Nothing contained in
this Agreement shall give Global, directly or indirectly, the right to control
or direct U S WEST's operations prior to the Effective Time. Prior to the
Effective Time, each of U S WEST and Global shall exercise, consistent with the
terms and conditions of this Agreement, complete control and supervision over
their respective operations.

                             ADDITIONAL AGREEMENTS

          Section 7.1 Joint Proxy Statement and the Registration Statement. (a)
As promptly as practicable after the execution and delivery of this Agreement
but in no event later than August 31, 1999, U S WEST and Global shall cause
Parent to, and Parent shall, prepare and file with the SEC the Registration
Statement, provided that such Registration Statement shall in no event be filed
prior to the mailing of the joint proxy statement in connection with the
Frontier Merger, and they shall use all reasonable efforts to have the
Registration Statement declared effective by the SEC under the Securities Act,
and the Parties shall prepare and file with the SEC, and shall use all
reasonable efforts to have cleared by the SEC, and promptly thereafter shall
mail to the holders of record of shares of U S WEST Common Stock and Global
Common Stock, the Joint Proxy Statement; provided, however, that Global and U S
WEST shall not mail or otherwise furnish the Joint Proxy Statement to their
respective stockholders unless and until:

                   (i)  they have received notice from the SEC that the
         Registration Statement is effective under the Securities Act;

                   (ii)  Global shall have received a letter of its independent
         accountants, dated a date within two (2) business days prior to the
         date of the first mailing of the Joint Proxy Statement, and addressed
         to Global, in form and substance reasonably satisfactory to Global and
         customary in scope and substance for "cold comfort" letters delivered
         by independent public accountants in connection with registration
         statements on Form S-4 with respect to the financial statements of U S
         WES included in the Joint Proxy Statement and the Registration
         Statement; and

                   (iii) U S WEST shall have received a letter of its
         independent accountants, dated a date within two (2) business days
         prior to the date of the first mailing of the Joint 

                                     -44-

 
         Proxy Statement, and addressed to U S WEST, in form and substance
         reasonably satisfactory to U S WEST and customary in scope and
         substance for "cold comfort" letters delivered by independent public
         accountants in connection with registration statements on Form S-4 with
         respect to the financial statements of Global included in the Joint
         Proxy Statement and the Registration Statement.

                  (b)      The Parties will cooperate in the preparation of the
Joint Proxy Statement and the Registration Statement and in having the
Registration Statement declared effective as soon as practicable.

          Section 7.2 Global and U S WEST Stockholders' Meetings and
Consummation of the Mergers. (a) As promptly as practicable after the
Registration Statement is declared effective under the Securities Act (but in
any event not prior to consummation of the Frontier Merger), Global shall duly
give notice of, convene and hold a meeting of its stockholders (the "Global
Stockholders' Meeting") in accordance with Bermuda Law for the purpose of
obtaining the approval of Global stockholders required to approve this Agreement
and the transactions contemplated hereby (the "Global Stockholder Approval") and
shall, subject to the provisions of Section 7.2(b) hereof, through its Board of
Directors, recommend to its stockholders the approval of this Agreement and the
transactions contemplated hereby and shall use its best efforts to obtain the
Global Stockholder Approval.

                  (b) Neither the Board of Directors of Global nor any committee
thereof shall (i) except as expressly permitted by this Section 7.2(b),
withdraw, qualify or modify, or propose publicly to withdraw, qualify or modify,
in a manner adverse to U S WEST, the approval or recommendations of such Board
of Directors or such committee of the approval of this Agreement and the
transactions contemplated hereby, (ii) approve or recommend, or propose publicly
to approve or recommend, any Alternative Transaction, or (iii) cause Global to
enter into any letter of intent, agreement in principle, acquisition agreement
or other similar agreement (each a "Global Acquisition Agreement") related to
any Alternative Transaction. Notwithstanding the foregoing, in the event that
prior to the time the Global Stockholder Approval is obtained, the Board of
Directors of Global determines in good faith, after it has received a Global
Superior Proposal (as defined below) and after receipt of advice from outside
counsel, that the failure to do so would result in a reasonable likelihood that
the Board of Directors of Global would breach its fiduciary duties to Global
stockholders under applicable law, then the Board of Directors of Global may
(subject to this and the following sentences) inform Global stockholders that it
no longer believes that the transactions contemplated by this Agreement are
advisable and no longer recommends approval of this Agreement and the
transactions contemplated hereby (a " Global Subsequent Determination"), but
only at a time that is after the fifth business day following U S WEST's receipt
of written notice advising U S WEST that the Board of Directors of Global has
received a Global Superior Proposal specifying the material terms and conditions
of such Global Superior Proposal (and including a copy thereof with all
accompanying documentation, if in writing), identifying the person making such
Global Superior Proposal and stating that it intends to make a Global Subsequent
Determination. After providing such notice, Global shall provide a reasonable
opportunity to U S WEST to make such adjustments in the terms and conditions of
this Agreement as would enable Global to proceed with its recommendation to its
stockholders without a Global Subsequent Determination; provided, however, that
any such adjustment shall be at the 

                                     -45-

 
discretion of the Parties at the time. For purposes of this Agreement, a "Global
Superior Proposal" means any proposal (on its most recently amended or modified
terms, if amended or modified) made by a Third Party to enter into an
Alternative Transaction which the Board of Directors of Global determines in its
good faith judgment (based on, among other things, the advice of a financial
advisor of nationally recognized reputation) to be more favorable to Global's
stockholders than the transactions contemplated by this Agreement taking into
account all relevant factors (including whether, in the good faith judgment of
the Board of Directors of Global, after obtaining the advice of a financial
advisor of nationally recognized reputation, the Third Party is reasonably able
to finance the transaction, and any proposed changes to this Agreement that may
be proposed by U S WEST in response to such Alternative Transaction).

                  (c) As promptly as practicable after the Registration
Statement is declared effective under the Securities Act, U S WEST shall duly
give notice of, convene and hold a meeting of its stockholders (the "U S WEST
Stockholders' Meeting") in accordance with Delaware Law for the purposes of
obtaining the approval of U S WEST Stockholders required to approve this
Agreement and the transactions contemplated hereby (the "U S WEST Stockholder
Approval") and shall, subject to the provisions of Section 7.2(d) hereof,
through its Board of Directors, recommend to its stockholders the approval and
adoption of this Agreement and the transactions contemplated hereby and shall
use its best efforts to obtain the U S WEST Stockholder Approval.

                  (d) Neither the Board of Directors of U S WEST nor any
committee thereof shall (i) except as expressly permitted by this Section
7.2(d), withdraw, qualify or modify, or propose publicly to withdraw, qualify or
modify, in a manner adverse to Global, the approval or recommendation of such
Board of Directors or such committee of this Agreement or the transactions
contemplated hereby, (ii) approve or recommend, or propose publicly to approve
or recommend, any Alternative Transaction, or (iii) cause U S WEST to enter into
any letter of intent, agreement in principle, acquisition agreement or other
similar agreement (each, a "U S WEST Acquisition Agreement") related to any
Alternative Transaction. Notwithstanding the foregoing, in the event that prior
to the time U S WEST Stockholder Approval is obtained, the Board of Directors of
U S WEST determines in good faith, after it has received a U S WEST Superior
Proposal (as defined below) and after receipt of advice from outside counsel,
that the failure to do so would result in a reasonable possibility that the
Board of Directors of U S WEST would breach its fiduciary duties to U S WEST
stockholders under applicable law, then the Board of Directors of U S WEST may
(subject to this and the following sentences) inform U S WEST stockholders that
it no longer believes that the transactions contemplated by this Agreement are
advisable and no longer recommends approval of this Agreement and the
transactions contemplated hereby (a "U S WEST Subsequent Determination"), but
only at a time that is after the fifth business day following Global's receipt
of written notice advising Global that the Board of Directors of U S WEST has
received a U S WEST Superior Proposal specifying the material terms and
conditions of such U S WEST Superior Proposal (and including a copy thereof with
all accompanying documentation, if in writing), identifying the person making
such U S WEST Superior Proposal and stating that it intends to make a U S WEST
Subsequent Determination. After providing such notice, U S WEST shall provide a
reasonable opportunity to Global to make such adjustments in the terms and
conditions of this Agreement as would enable U S WEST to proceed with its
recommendation to its stockholders without a U S WEST Subsequent Determination;
provided, however, that any such adjustment 

                                     -46-

 
shall be at the discretion of the Parties at the time. For purposes of this
Agreement a "U S WEST Superior Proposal" means any proposal (on its most
recently amended or modified terms, if amended or modified) made by a Third
Party to enter into an Alternative Transaction which the Board of Directors of U
S WEST determines in its good faith judgment (based on, among other things, the
advice of a financial advisor of nationally recognized reputation) to be more
favorable to U S WEST's stockholders than the transactions contemplated by this
Agreement, taking into account all relevant factors (including whether, in the
good faith judgment of the Board of Directors of U S WEST, after obtaining the
advice of a financial advisor of nationally recognized reputation, the Third
Party is reasonably able to finance the transaction, and any proposed changes to
this Agreement that may be proposed by Global in response to such Alternative
Transaction).

          Section 7.3 Additional Agreements. (a) Upon the terms and subject to
the conditions hereof and as soon as practicable after the conditions set forth
in Article VIII hereof have been fulfilled or waived, each of the Parties,
including, without limitation, Parent, U S WEST Merger Sub and Global Merger Sub
when they become parties hereto, shall execute in the manner required by
Delaware Law and Bermuda Law and deliver to and file with the Secretary of State
of the State of Delaware and with the Registrar of Companies in Bermuda such
instruments and agreements as may be required by Delaware Law and Bermuda Law
and the Parties shall take all such other and further actions as may be required
by law to make the Mergers effective. Prior to the filings referred to in this
Section 7.3(b), a closing (the "Closing") will be held at the offices of
Cadwalader, Wickersham & Taft (or such other place as the Parties may agree) for
the purpose of confirming all the foregoing. The Closing will take place upon
the fulfillment or waiver of all of the conditions to closing set forth in
Article VIII of this Agreement, or as soon thereafter as practicable (the date
of the Closing being herein referred to as the "Closing Date").

          (b) Each of the Parties will comply in all material respects with all
applicable laws and with all applicable rules and regulations of any
Governmental or Regulatory Authority, in connection with its execution, delivery
and performance of this Agreement and the transactions contemplated hereby. Each
of the Parties agrees to use all commercially reasonable efforts to obtain in a
timely manner all necessary waivers, consents and approvals and to effect all
necessary registrations and filings, and to use all commercially reasonable
efforts to take, or cause to be taken, all other actions and to do, or cause to
be done, all other things necessary, proper or advisable to consummate and make
effective as promptly as practicable the transactions contemplated by this
Agreement. Without limiting the generality of the foregoing, each of Global and
U S WEST shall promptly prepare and file a Premerger Notification in accordance
with the HSR Act, shall promptly comply with any requests for additional
information, and shall use its commercially reasonable efforts to obtain
termination of the waiting period thereunder as promptly as practicable.

          Section 7.4  Notification of Certain Matters. Each of Global and U S
WEST shall give prompt notice to the other of the following:
                       
          (a) the occurrence or nonoccurrence of any event (including, without
limitation, with respect to Global, the transactions contemplated by the
Frontier Merger Agreement) whose occurrence or nonoccurrence would be likely to
cause either (i) any

                                     -47-

 
representation or warranty contained in this Agreement to be untrue, inaccurate
or incomplete in any material respect at any time from the date hereof to the
Effective Time, in which case such Party shall promptly update and deliver to
the other Party any Schedules hereto which require an update to remain true,
accurate and complete, or (ii) directly or indirectly, any Material Adverse
Effect on such Party;

                  (b)    any material failure of such Party, or any officer,
director, employee or agent of any thereof, to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder;

                  (c)      any facts relating to such Party which would make it
necessary or advisable to amend the Joint Proxy Statement or the Registration
Statement in order to make the statements therein not misleading or to comply
with applicable law; provided, however, that the delivery of any notice pursuant
to this Section 7.4 shall not limit or otherwise affect the remedies available
hereunder to the Party receiving such notice; and

                  (d)      its becoming aware of any fact, event or other
information which reveals or indicates that the consummation of the Mergers
would or may result in any illegality, forfeiture or loss on the part of either
Parent, U S WEST or any of its Subsidiaries, or Global or any of its
Subsidiaries.

          Section 7.5 Access to Information. (a) From the date hereof to the
Effective Time, each of Global and U S WEST shall, and shall cause its
respective Subsidiaries, and its and their officers, directors, employees,
auditors, counsel and agents to afford the officers, employees, auditors,
counsel and agents of the other Party reasonable access during regular business
hours to such Party's and its Subsidiaries' officers, employees, auditors,
counsel, agents, properties, offices and other facilities and to all of their
respective books and records, and shall furnish the other with all financial,
operating and other data and information as such other Party may reasonably
request.

                  (b) Each of Global and U S WEST agrees that all non-public,
confidential information so received from the other Party shall be deemed
received pursuant to the confidentiality agreement, dated as of May 3, 1999,
between Global and U S WEST (the "Confidentiality Agreement") and such Party
shall, and shall cause its Subsidiaries and each of its and their respective
officers, directors, employees, financial advisors, attorneys, accountants,
consultants and agents ("Party Representatives ), to comply with the provisions
of the Confidentiality Agreement with respect to such information, and the
provisions of the Confidentiality Agreement are hereby incorporated herein by
reference with the same effect as if fully set forth herein.

                  (c) Global shall use its commercially reasonable efforts to
allow U S WEST and its Party Representatives such access to Frontier and its
Party Representatives and Frontier's books and records and facilities as is
allowed Global in connection with the Frontier Acquisition, subject to the
execution of a confidentiality agreement acceptable to Frontier.

          Section 7.6  Public Announcements.  Global and U S WEST shall develop
a joint communications plan and each Party shall use all reasonable efforts to
ensure that all press 

                                     -48-

 
releases and other public statements with respect to the transactions
contemplated hereby shall be consistent with such joint communications plan or,
to the extent inconsistent therewith, shall have received the prior written
approval of the other Parties.

          Section 7.7 Cooperation. (a) Upon the terms and subject to the
conditions hereof, each of the Parties agrees to use its commercially reasonable
efforts to take or cause to be taken all actions and to do or cause to be done
all things necessary, proper or advisable to consummate the transactions
contemplated by this Agreement and shall use its commercially reasonable efforts
to obtain all necessary waivers, consents and approvals from any Governmental or
Regulatory Authority or other Person, and to effect all necessary filings under
the Securities Act, the Exchange Act and the HSR Act. Global and U S WEST agree
to abide by and comply with any conditions that may be imposed by any
Governmental or Regulatory Authority as a condition of its waiver, consent or
approval, including, without limitation, any conditions which are necessary in
order to be in compliance with Section 271 of the Telecommunications Act of 1996
("Section 271 Compliance"). The Parties shall (i) cooperate in responding to
inquiries from, and making presentations to, Governmental or Regulatory
Authorities; (ii) promptly inform the other Party of any material oral or
written communication received by such Party from, or given by such party to any
Governmental or Regulatory Authority and of any material communication received
or given in connection with any proceeding by a private Party, in each case
regarding any of the transactions contemplated hereby; and (iii) consult with
each other in advance of any meeting or conference with, or of making any filing
or other written submission to, any such Governmental or Regulatory Authority
or, in connection with any proceeding by a private party, with any other Person,
and to the extent permitted by the applicable Governmental or Regulatory
Authority or other Person, give the other Party the opportunity to attend and
participate in such meetings and conferences, or to review and approve any such
filing or other written submission, in each case regarding the Mergers. U S WEST
and Global shall cooperate with each other, and use their respective
commercially reasonable efforts to take or cause to be taken and to do or cause
to be done all things necessary, proper or advisable to ensure compliance with
the Telecommunications Act of 1996, including, without limitation, the amendment
of this Agreement as may be necessary, proper or advisable in order to ensure
such compliance.

                  (b)  Notwithstanding subsection (a), U S WEST and Global shall
use their reasonable best efforts to secure or obtain any Required Regulatory
Approvals, including, without limitation, certificates for operating rights and
licenses for use of spectrum.

                  (c)  Each of U S WEST and Global shall cooperate with each
other to eliminate or reduce to the extent possible any illegality, forfeiture
or loss of which one may have notified the other pursuant to Section 7.4(d) in
order to permit the consummation of the Mergers.

          Section 7.8 Indemnification, Directors' and Officers' Insurance. For a
 period of six (6) years after the Effective Time, (a) U S WEST and Global shall
 maintain in effect the current provisions regarding indemnification of officers
 and directors contained in the charter and bylaws of U S WEST and Global and
 each of their respective Subsidiaries and any directors, officers or employees
 indemnification agreements of U S WEST and Global and their respective
 Subsidiaries, (b) U WEST and Global shall maintain in effect the current
 policies of directors' and officers' liability insurance and fiduciary
 liability insurance maintained by 

                                     -49-

 
 U S WEST and Global, respectively, (provided that U S WEST may substitute
 therefor policies of at least the same coverage and amounts containing terms
 and conditions which are, in the aggregate, no less advantageous to the insured
 in any material respect) with respect to claims arising from facts or events
 which occurred on or before the Effective Time, and (c) U S WEST and Global
 shall indemnify the directors and officers of U S WEST and Global,
 respectively, to the fullest extent to which U S WEST and Global are permitted
 to indemnify such officers and directors under their respective charters and
 bylaws and applicable law.

          Section 7.9  Employee Benefit Plans.  Except as otherwise provided
herein or set forth on Schedule 6.2, Global and U S WEST agree that, unless
otherwise mutually agreed, they (or their Subsidiaries, as applicable) may, but
shall have no obligation to, maintain the U S WEST Benefit Plans and the Global
Benefit Plans as separate plans after the Effective Time with respect to
employees covered by such plans immediately prior to the Effective Time.

          Section 7.10  Officers of Parent. Solomon D. Trujillo and Robert
Annunziata shall hold the position of Co-Chairmen of Parent, and they each shall
also hold the position of Co-Chief Executive Officers of Parent. The Co-Chief
Executive Officers of Parent shall appoint the senior management of Parent
following the Effective Time.


          Section 7.11  Stock Exchange Listing.  Each of the Parties shall use
its reasonable best efforts to obtain, prior to the Effective Time, the approval
for listing on the NYSE or Nasdaq, effective upon official notice of issuance,
of the shares of Parent Class A Common Stock and Parent Class B Common Stock.


          Section 7.12  Post-Mergers Parent Board of Directors; Executive
Committee. (a) At the Effective Time, the total number of persons serving on the
Board of Directors of Parent shall be twenty two (22) (unless otherwise agreed
in writing by Global and U S WEST prior to the Effective Time). The persons to
serve initially on the Board of Directors of Parent at the Effective Time shall
be selected as follows: ten (10) directors shall be designated by each of U S
WEST and Global, and the remaining two (2) directors shall be designated by U S
WEST and shall be independent directors not affiliated with U S WEST or Global
in any manner; provided, however, that the additional two (2) directors shall be
reasonably satisfactory to Global. Each such person shall serve as a director
until their successor is elected or appointed in accordance with the Bylaws of
Parent and qualified.

          (b) The Board of Directors of Parent shall have at the Effective Time
an Executive Committee, which shall be comprised of three (3) directors
designated by U S WEST and three (3) directors designated by Global, and which
shall exercise the authority granted to it by the Bylaws of Parent. Each of
Global and U S WEST shall take such action as shall reasonably be deemed by
either thereof to be advisable to give effect to the provisions set forth in
this section, including but not limited, to incorporating such provisions in the
Bylaws of Parent in effect at the Effective Time. The Bylaws of Parent shall
provide that the executive committee will have the full powers which may be
granted to it by the Board of Directors under Delaware Law, except as otherwise
provided by resolutions of the Board of Directors.

          Section 7.13 No Shelf Registration. Parent shall not be required to
amend or maintain the effectiveness of the Registration Statement for the
purpose of permitting resale of 

                                     -50-

 
the shares of Parent Class A Common Stock or Parent Class B Common Stock
received pursuant hereto by the Persons who may be deemed to be "affiliates" of
Global or U S WEST within the meaning of Rule 145 promulgated under the
Securities Act. The shares of Parent Class A Common Stock or Parent Class B
Common Stock issuable upon exercise of options pursuant to Section 2.8 or
Section 3.8 hereof shall be registered under the Securities Act and such
registration shall be effective at the time of issuance.

          Section 7.14 Affiliates. Each of Global and U S WEST (i) has disclosed
to the other on Schedule 7.14 hereof all persons who are, or may be, as of the
date hereof its Affiliates for purposes of Rule 145 under the Securities Act,
and (ii) shall use all reasonable efforts to cause each person who is identified
as an "affiliate" of it on Schedule 7.14 to deliver to the other as promptly as
practicable but in no event later than the Closing Date, a signed agreement
substantially in the form previously agreed to by Global and U S WEST. Global
and U S WEST shall notify each other from time to time of any other persons who
then are, or may be, such an "affiliate" and use all reasonable efforts to cause
each additional person who is identified as an "affiliate" to execute a signed
agreement as set forth in this Section 7.14.

          Section 7.15 Blue Sky.  Global and U S WEST will use their best
efforts to obtain prior to the Effective Time all necessary state securities or
"blue sky" Permits and approvals required to permit the distribution of the
shares of Parent Class A Common Stock or Parent Class B Common Stock to be
issued in accordance with the provisions of this Agreement.


          Section 7.16 Tax-Free Exchange.  Each of the Parties will use its
reasonable efforts, and each agrees to cooperate with the other and provide each
other with such documentation, information and materials, as may be reasonably
necessary, proper or advisable, to cause the transactions to be effected
pursuant to this Agreement to qualify for U.S. federal income tax purposes as a
tax-free exchange or a series of exchanges.

          Section 7.17 Determination of Class B to Class A Value Ratio. At such
time as may be agreed by U S WEST and Global, but in no event later than sixty
(60) days prior to the anticipated Effective Time, U S WEST and Global will each
retain, and provide relevant information to, a nationally recognized investment
banking firm (each, an "appraiser") to determine the "Class B to Class A Value
Ratio". The Class B to Class A Value Ratio shall be determined by dividing the
"Global Value" by the "Local Value" (rounded to the nearest 1/10,000). The
Global Value shall represent the fully distributed equity value of the Global
Group (as such term is defined for the purposes of such determination pursuant
to Section 7.24), and the Local Value shall represent the fully distributed
equity value of the Local Group (as such term is defined for the purposes of
such determination pursuant to Section 7.24), in each case, calculated as if
each such group were an independent, publicly traded and widely held company.
Global and U S WEST shall instruct the appraisers to meet and work together for
a period of two weeks to resolve their differences, if any, as to the
calculation of such ratios. If the appraisers are able to resolve their
difference as to such calculations during such period, then the joint decision
of the appraisers will be the Class B to Class A Value Ratio. If the difference
between the determinations submitted by each appraiser is less than 10.0 percent
of the lowest of such determinations, then the 

                                     -51-

appraisers will in turn select a third nationally recognized banking firm to
make such determination. The average of the determinations submitted by the
appraisers shall be the Class B to Class A Value Ratio. If the difference
between the determinations submitted by each appraiser equals or exceeds 10.0
percent of the lowest of such determinations, then the appraisers will in turn
select a third nationally recognized investment banking firm to make such
determination. The average of the determinations provided by such third firm and
the determination submitted by the appraiser retained by Global or U S WEST that
is closest to the determination provided by such third firm shall be the Class B
to Class A Value Ratio; provided, however, that the Class B to Class A Value
Ratio shall not be less than the lower of the proposed Class B to Class A Value
Ratios submitted by the appraisers nor greater than the higher of the proposed
Class B to Class A Value Ratios submitted by the appraisers.

                  In determining the Class B to Class A Value Ratio, each
appraiser (including any third investment banking firm engaged as provided above
in this Section 7.17) will employ methodologies and analyses consistent with
those traditionally utilized by investment banking firms in performing public
company valuations including:

                   (i)  reviewing publicly available information concerning the
proposed businesses, assets and liabilities of such groups,

                   (ii) reviewing other financial information concerning the
proposed businesses, assets and liabilities of such groups, including financial
forecasts to be provided by Global and U S WEST management relating to the
proposed businesses, assets and liabilities of such groups, respectively,
including any costs or benefits accruing to such groups as a result of the
Mergers as well as the intercompany relationships between the Global Group and
the Local Group,

                   (iii) performing reasonable due diligence, including
discussing the proposed businesses, assets and liabilities of such groups with
officers of Global and U S WEST, and

                   (iv)  considering such other information, financial studies,
analyses, investigations and financial, economic and market criteria that the
appraiser deems relevant.

Such valuations will not give effect to any tracking stock, initial public
offering, shareholder concentration or other similar factors that may adversely
impact the Global Value or Local Value. Global and U S WEST shall each use
reasonable best efforts to supply to the appraisers such information, analyses
and access to books, records and personnel as the appraisers may reasonably
request. The fees and expenses of the third appraiser will be split evenly
between U S WEST and Global.

          Section 7.18 Permitted Acquisitions. During the period from the date
of this Agreement through the Closing Date, each of Global and U S WEST may
engage in acquisition transactions taking the form of a stock acquisition, asset
acquisition, merger or similar type form of transaction ("Acquisitions");
provided, however, that such transactions comply with this Section 7.18. Each of
Global and U S WEST may engage in Acquisitions having an aggregate consideration
value of $3 billion (including assumptions of debt) and in the case of Global
except as set forth on Schedule 7.18. Any Acquisition in excess of such amount
shall require the prior written consent of the other party.

                                     -52-

 
          Section 7.19 Certain Transactions. (a) Global will (i) use its
reasonable best efforts to close the transactions contemplated by the Frontier
Merger Agreement (the "Frontier Acquisition") in accordance with the terms
thereof, (ii) not take any action which would materially adversely impact the
timing of the closing of the transactions contemplated by the Frontier Merger
Agreement or the ability of Global to satisfy the conditions precedent to the
closing of the transactions contemplated by the Frontier Merger Agreement, and
(iii) not waive or amend any material economic provision of the Frontier Merger
Agreement without the prior written approval of U S WEST; provided, however,
that, without U S WEST's consent, Global may increase the merger consideration
in the Frontier Merger in the event an Acquisition Proposal (as defined in the
Frontier Merger Agreement) is made to Frontier, but, if the increase is in cash,
not in excess of the amount then available for acquisitions set forth in Section
7.18 hereof which shall thereafter reduce the amounts available for acquisition.

                  (b) Global will use its reasonable efforts to close the
transactions contemplated by the agreement governing Global's acquisition (the
"C&W Acquisition Agreement") of Cable & Wireless Global Marine ("C&W") in
accordance with the terms thereof, and (ii) not take any action which would
materially adversely impact the timing of the closing of the transactions
contemplated by the C&W Acquisition Agreement or the ability of Global to
satisfy the conditions precedent to the closing of the transactions contemplated
by the C&W Acquisition Agreement.

          Section 7.20 Interim Dividend Policy. Global shall not, without the
prior written consent of U S WEST, declare, set aside or pay any dividend or
distribution payable in cash, stock, property or otherwise (a "Dividend") with
respect to shares of Global Common Stock. U S WEST shall be permitted, without
the prior written consent of Global, to declare and pay Dividends with respect
to shares of U S WEST Common Stock in the ordinary course of business and in a
manner consistent with past practice not in excess of $0.75 per quarter. In
addition, U S WEST may declare and pay to stockholders of record on the date
immediately prior to the Effective Time (i) a special dividend of $1.00 per
share and (ii) the pro rata portion of the then regular quarterly dividend
through such date.

          Section 7.21 Subsidiary Definition. Upon consummation of the Frontier
Acquisition and the C&W Acquisition, Frontier and C&W shall each be a Subsidiary
of Global for all purposes of this Agreement; provided that (i) in no event
shall Global be required to make or be deemed to be required to make any
representation and warranty pursuant to Article V or Section 9.3 regarding
Frontier, C&W or any of their respective subsidiaries if such representation and
warranty was not made or given to Global in connection with the consummation of
the Frontier Acquisition, in the case of Frontier and its Subsidiaries, and the
acquisition of C&W, in the case of C&W and its Subsidiaries, and (ii) no breach
of a representation and warranty shall be deemed to exist by reason of the
failure of any Schedule referred to in Article V which requires disclosure of
specified information concerning Global Subsidiaries to include responsive
disclosure concerning Frontier, C&W or any of their respective subsidiaries.

          Section 7.22  Exchange Procedures. If, in consultation with Nasdaq and
the NYSE, the parties determine that the procedures contemplated by Section 2.4
may interfere with the orderly market trading of the Global Common Stock and/or
U S WEST Common Stock or 

                                     -53-

 
may otherwise be inadvisable, then the parties shall negotiate in good faith to
provide for alternative procedures.


         Section 7.23    Services Agreement. U S WEST and Global will use
reasonable best efforts to enter into a retail marketing and services agreement
within thirty (30) days of the date of this Agreement covering the marketing of
U S WEST's services and the purchase by U S WEST of Global's services. U S WEST
and Global further agree to use reasonable best efforts to enter into an arms-
length agreement to form and operate outside of U S WEST's service territory a
data-focused competitive local exchange carrier.

          Section 7.24 Certain Definitions. No later than the time the Parties
engage the appraisers pursuant to Section 7.17, U S WEST and Global will agree
on the definitions of Global Group and Local Group (as such terms are
contemplated to be used for purposes of Parent's Certificate of Incorporation)
to be used for purposes of the determination of the Class B to Class A Value
Ratio and for purposes of Parent's Certificate of Incorporation, which
determination shall, to the extent practicable, be made consistent with the
present intent of the parties as set forth in Section 1.1.


                                 ARTICLE VIII

                          CONDITIONS TO THE MERGERS 

          Section 8.1  Conditions to Obligations of Each Party to Effect the

by the requisite vote of the stockholders of Parent, in each case in accordance
with Delaware Law and Bermuda Law and the rules of the Nasdaq and the NYSE, as

                 (b) Legality.  No federal, state or foreign statute,
rule, regulation, executive order, decree or injunction shall have been enacted,
entered, promulgated or enforced by any Governmental or Regulatory Authority
which is in effect and has the effect of (i) making either of the Mergers
illegal or otherwise prohibiting the consummation of either of the Mergers, or
(ii) creating a Material Adverse Effect on Global, or on U S WEST;

                 (c) HSR Act. Any waiting period applicable to the consummation
of the Mergers under the HSR Act shall have expired or been terminated;

                  (d) Regulatory Matters. All Permits from, approvals of, or
declarations or filings with, and all expirations of waiting periods imposed by,

complied in all material respects with all agreements and covenants required by

non-recognition transaction for both Global and Parent. In rendering such
opinion, Skadden, Arps, Slate, Meagher & Flom LLP may require and rely upon
representations and covenants including those contained in

U S WEST, provided that Global has received an opinion of Skadden, Arps, Slate,
Meagher & Flom LLP, dated prior to the Effective Time, that there exists a

warranty expressly speaks as of an earlier date, in which case it shall be true
and correct as of such date) except (i) for changes permitted under Section 6.2
hereof or otherwise contemplated by this Agreement, and (ii) for such failures
to be true and correct which in the aggregate would not reasonably be expected
to result in a Material Adverse Effect on Global.

                  (b) Agreements, Covenants. Global shall have performed or

the aggregate, results or would reasonably be expected to result in a Material
Adverse Effect on U S WEST, either with or without including its ownership of
Global and its Subsidiaries after the Merger, or a material adverse effect on
the consummation of the transactions contemplated hereby.

                  (c) Certificates. U S WEST shall have received a certificate
of an executive officer of Global to the effect set forth in paragraphs (a) and
(b) above.

Cadwalader, Wickersham & Taft, special counsel to U S WEST, dated as of the
Effective Time, in form and substance reasonably satisfactory to U S WEST,
substantially to the effect that, on the basis of the facts, representations and
assumptions set forth or referred to in such opinion, the consummation of the
transactions to be effected pursuant to this Agreement (including the

U S WEST completed on June 12, 1998, to become taxable, including taxability
pursuant to Section 355(e) of the Code, (ii) constitute for U.S. federal income
tax purposes a tax-free exchange of shares of U S WEST Common stock for shares
of Parent Common Stock, and (iii) be a non-recognition transaction as to U S
WEST and Parent. Additionally, in the event the opinion referred to in Section
8.2(d)(ii) is not rendered with respect to Global or Parent, then U S WEST shall
not be obligated to effect the Mergers, notwithstanding a waiver of the
condition referred to in such clause by Global, provided that U S WEST has
received an opinion of Cadwalader, Wickersham & Taft, dated prior to the
Effective Time, that there exists a substantial likelihood of a Tax liability
that would represent a Material Adverse Effect to Global or Parent, as the case
may be. In rendering the opinion referred to in the first sentence of this
subsection (d), Cadwalader, Wickersham & Taft may require and rely upon
representations and covenants including those contained in certificates of
officers of Parent, U S WEST and Global and others.

                  (e) Affiliate Agreements.  U S WEST shall have received

other hardware, software and systems with which such Systems normally operate
and interact, including on-site backup, hot-site companion and disaster recovery
systems, as well as properly recording, retaining and manipulating such date
data; provided, however, that such other hardware, software and Systems are
themselves Year 2000 Compliant.
