         The summary descriptions contained in this Report of certain agreements
and documents are qualified in their entirety by reference to the complete texts
of such agreements and documents filed as Exhibits hereto,  which agreements and
documents are hereby incorporated herein by reference.

Item 1.  Security and issuer.

         This statement  relates to the Class A Common Stock, $.01 par value per
share (the "Class A Common  Stock"),  of Teleport  Communications  Group Inc., a
Delaware  corporation  (the "Issuer").  The principal  executive  offices of the
Issuer are at One Teleport Drive, Staten Island, New York 10311-1011.

         Each share of Class A Common Stock  entitles the holder to one vote and
each  share of Class B Common  Stock  entitles  the  holder  to 10 votes on each
matter to be voted upon by the holders of the Common  Stock.  The holders of the
shares of Class A Common Stock and Class B Common Stock vote as one class on all
matters  to be voted on by  stockholders,  including,  without  limitation,  the
election of  directors  and any  proposed  amendment to the Amended and Restated
Certificate  of  Incorporation  of the Issuer that would increase the authorized
number  of shares of Common  Stock or any class  thereof  or any other  class or
series of stock or  decrease  the  number of  authorized  shares of any class or
series of stock (but not below the number thereof then  outstanding),  except as
required by the Delaware  General  Corporation Law and except that, for a period
of five years from the date of the filing of the  Issuer's  Amended and Restated
Certificate  of  Incorporation,  so long as the holders of Class B Common  Stock
represent at least 50% of the voting power of the outstanding  Common Stock, the
approval of the  holders of a majority  of the Class B Common  Stock is required
for the Company to provide (i) wireless  communications  services that use radio
spectrum  for  cellular,   personal   communications   service  (PCS),  enhanced
specialized mobile radio (ESMR), paging, mobile telecommunications and any other
voice or data wireless services whether fixed or mobile; provided, however, that
the  Issuer may  provide  and brand  telecommunications  products  and  services
delivered    via    point-to-point    microwave    transmissions;    and    (ii)
telecommunications  services to residences;  provided,  however, that the Issuer
may provide telecommunications  services to residences to the extent required by
a regulatory authority having jurisdiction over the Issuer's business, including
requirements  of the Issuer's local  exchange  carrier  certificates  and common
carrier  obligations,  if any, or in any geographic  area in which such services
are offered as of July 1, 1996,  but only to the extent of the services  then so
offered.

Item 2.  Identity and background.

         This statement is filed pursuant to Reg.  ss.13(d)-1(f)(1) on behalf of
the following persons, who are collectively  referred to as the "Filing Persons"
and sometimes individually referred to as a "Filing Person":

         Continental Cablevision,  Inc., a Delaware corporation ("Continental"),

Officer of Continental  beneficially  owns 45,207,362  shares of Common Stock of
Continental, which represents approximately 31.86% of the aggregate voting power
of the outstanding capital stock of Continental, and, accordingly, may be deemed
to be a "controlling person" of Continental.

         Cox Teleport Partners,  Inc., a Delaware  corporation ("Cox Teleport"),
holds stock of the Issuer  reported  herein and is a wholly owned  subsidiary of

subsidiary of Cox Investment  Company,  Inc., a Delaware  corporation  ("CICI"),

which  is a  wholly  owned  subsidiary  of Cox  Enterprises,  Inc.,  a  Delaware
corporation  ("CEI").  As a trustee of the Barbara Cox Anthony Atlanta Trust and
of the Dayton Cox Trust A, Anne Cox Chambers exercises beneficial ownership over
an aggregate of approximately  69.6% of the outstanding capital stock of CEI. As
a trustee of the Anne Cox Chambers  Atlanta Trust and of the Dayton Cox Trust A,
Barbara  Cox  Anthony  exercises  beneficial  ownership  over  an  aggregate  of
approximately 69.6% of the outstanding capital stock of CEI. Thus, Mrs. Chambers
and Mrs.  Anthony  share  ultimate  control over CEI.  Cox is the fifth  largest
operator  of  cable  television  systems  in the  United  States  and is a fully
integrated,   diversified  media  and  broadband   communications  company  with
operations and investments in three related areas: (i) U.S. broadband  networks;
(ii) United Kingdom broadband networks; and (iii) cable television  programming.

CEI are publishing, cable television,  broadcasting and automobile auctions. The
principal office and business address of Cox Teleport, Cox, CHI, CICI and CEI is
1400 Lake Hearn Drive, Atlanta, Georgia 30319.

         Comcast  Corporation,  a Pennsylvania  corporation  ("Comcast"),  holds
stock of the Issuer  reported herein through a wholly owned  subsidiary  Comcast
Teleport,  Inc.  ("Comcast  Teleport"),  a  Delaware  corporation.   Comcast  is
principally  engaged  in the  development,  operation  and  management  of wired
telecommunications  including cable television and telephone services;  wireless
telecommunications include cellular,  personal communication services and direct
to home satellite television,  and content through programming  investments with
its principal office and business  located at 1500 Market Street,  Philadelphia,
PA 19102-2148.  As of February 29, 1996, Sural Corporation ("Sural"), a Delaware
corporation,  owned  1,845,037  shares  of  Class  A  Common  Stock  of  Comcast
Corporation.  Mr.  Ralph J.  Roberts,  and  members of his family own all of the
voting  securities of Sural.  Pursuant to Rule 13d-3 of the Securities  Exchange
Act of 1934, as amended (the  "Exchange  Act"),  Mr. Roberts is deemed to be the
beneficial  owner of the shares of Class A Common  Stock  owned by Sural.  As of
February 29, 1996,  Sural was the sole owner of Comcast's  Class B Common Stock.
Pursuant  to Rule 13d-3 of the  Exchange  Act,  Mr.  Roberts is deemed to be the
beneficial  owner of the shares of Class B Common  Stock  owned by Sural.  Since
each share of Class B Common Stock is entitled to 15 votes,  the shares of Class
A Common Stock and Class B Common Stock owned by Sural constitute  approximately
79% of the voting  power of the two classes of  Comcast's  voting  Common  Stock
combined.  The Class B Common Stock is  convertible on a  share-for-share  basis
into  Class A Common  Stock or Class A Special  Common  Stock.  If Sural and Mr.
Roberts  were to  convert  the Class B Common  Stock  which  they are  deemed to
beneficially own into Class A Common Stock,  Mr. Roberts would  beneficially own
11,507,232  shares of Class A Common Stock  (approximately  24.6% of the Class A
Common Stock).

         Tele-Communications,  Inc., a Delaware corporation  ("TCI"),  currently
holds the stock of the Issuer  reported  herein through an indirect  subsidiary,
TCI Teleport,  Inc., a Colorado  corporation.  TCI is principally engaged in the
construction,  acquisition,  ownership and operation of cable television systems
and the provision of  satellite-delivered  video entertainment,  information and
home  shopping   programming  services  to  various  video  distribution  media,
principally  cable  television  systems.  Its principal  office and business are
located at 5619 DTC Parkway, Englewood, Colorado 80111.

         Information  concerning  the  executive  officers and  directors of the
Filing Persons and the persons  controlling such Filing Persons,  if any, is set
forth in Exhibit 99.2 to this statement.  Unless  otherwise set forth in Exhibit
99.2,  each of such executive  officers and directors is a citizen of the United
States.  None of the Filing  Persons  nor, to the best of their  knowledge,  any
person named in Exhibit 99.2 to this  statement,  during the last five years (i)
has been convicted in a criminal  proceeding  (excluding  traffic violations and
similar  misdemeanors);  or (ii)  has been a party  to a civil  proceeding  of a
judicial or  administrative  body of competent  jurisdiction  and as a result of
such proceeding was or is subject to a judgment, decree or final order enjoining
future violations of, or prohibiting or mandating activities subject to, federal
or state securities laws or finding any violation with respect to such laws.

         A joint filing agreement among the Filing Persons is attached hereto as

Item 3.  Source and amount of funds or other consideration.

         Prior to the initial  public  offering of 27,025,000  shares of Class A
Common Stock by the Issuer (the "Offering"),  the Issuer was owned by the Filing
Persons  (TCI  (30%),  Cox (30%),  Comcast  (20%) and  Continental  (20%)).  The
business was operated through the Issuer and, beginning in 1992, TCG Partners, a
New York general  partnership  owned by the Filing Persons prior to the Offering
in the same  percentages  as the Issuer.  The Issuer,  TCG Partners,  the Filing
Persons and other cable operators  invested in  partnerships  (the "Local Market
Partnerships") to develop and operate local  telecommunications  networks, which
were  managed by the  Issuer.  Prior to the  Offering,  the Filing  Persons  (i)
exchanged their interests in TCG Partners and the Local Market  Partnerships and
(ii) contributed outstanding indebtedness owed by the Issuer to them in exchange
for shares of Class B Common Stock, $.01 par value per share, of the Issuer (the
"Class B Common Stock" and,  together with the Class A Common Stock, the "Common
Stock"))   in  a   reorganization   of  the   Teleport-related   entities   (the
"Reorganization")  pursuant to a Reorganization  Agreement (the  "Reorganization
Agreement").  The Filing  Persons  received the  following  numbers of shares of
Class B Common Stock in exchange for such partnership interests and indebtedness
in the Reorganization:

               Continental                        11,761,260
               Cox                                18,045,594
               Comcast                            11,621,988
               TCI                                27,821,388

         Also, pursuant to the Reorganization Agreement,  prior to the Offering,
each share of common stock of the Issuer  outstanding  immediately  prior to the
Reorganization  was automatically  converted into shares of Class B Common Stock
on a 42,000 for 1 basis.  The Filing Persons  received the following  numbers of
shares of Class B Common Stock in exchange for their  existing  shares of common
stock:

               Continental                        14,000,070
               Cox                                21,042,000
               Comcast                            14,000,070
               TCI                                20,958,000

As part  of the  Reorganization,  TCI  also  acquired  beneficial  ownership  of
1,011,528  shares  of Class A Common  Stock in  consideration  for two  proposed
transfers to the Issuer of certain Local Market  Partnership  interests  that it
has acquired or expects to acquire from an unrelated third party.

         Shortly after the Offering,  pursuant to the Reorganization  Agreement,
the Issuer redeemed from  Continental  7,975,738  shares of Class B Common Stock
received by Continental in the  Reorganization at a price per share equal to the
initial public offering price of the Class A Common Stock in the Offering,  less
underwriting  discounts  and a pro rata  portion of the  registration  fees,  or
approximately  $15.17 per share.  Continental  also  acquired  in the  Offering,
through  Continental  Investments,  75,000 shares of Class A Common Stock at the
initial public offering price of $16.00 per share.  The purchase was made out of
funds provided from working  capital.  The information  required to be disclosed
under  Item 3 for the  persons  named in  Exhibit 2 to this  Report is listed on
Exhibit 2 hereto and is incorporated herein by reference.

Item 4.  Purpose of transaction.

         The Reorganization was necessary to simplify the ownership structure of
the Issuer in preparation  for the Offering.  Prior to the Offering,  the filing
persons owned 100% of the outstanding common stock of Issuer. As a result of the
Offering  and the  Reorganization,  the  Filing  Persons,  who  hold  all of the
outstanding  Class B Common Stock and control  approximately 98% of the combined
voting  power of the  Issuer's  outstanding  Common  Stock,  generally  have the
collective  ability to  control  all  matters  requiring  stockholder  approval,
including the nomination and election of directors.

         The  Filing  Persons  have  entered  into  the  Amended   Stockholders'
Agreement,  as defined below,  which provides that the Board of Directors of the
Issuer will  consist of 13  directors  and that at each annual  meeting at which
directors  are  elected,  the Filing  Persons will vote their shares in favor of
nominees for director to be designated as follows:  (i) the Filing  Persons will
designate  10  nominees  (with the right of a holder of Class B Common  Stock to
designate one or more nominees depending on the percentage of the Class B Common
Stock held by it), (ii) the Board of Directors of the Issuer will  designate the
Chief  Executive  Officer  of the  Issuer  as a  nominee  and (iii) the Board of
Directors,  with the  unanimous  approval of the holders of Class B Common Stock
that have the right to  designate  nominees  for  director,  will  designate  by
unanimous  consent two  individuals  who are neither  employed by nor affiliated
with the Issuer or any holder of Class B Common Stock as nominees for  director.
Continental does not currently have any right to designate a director.  See Item
6. Except as noted below, none of such persons,  or to the best of such person's
knowledge,  any of its executive officers,  directors or controlling persons has
any present  plans or  proposals  which  relate to or would result in any of the
following:

         (a) The  acquisition  by any  person of  additional  securities  of the
Issuer or the disposition of securities of the Issuer;

         (b)  An  extraordinary   corporate  transaction,   such  as  a  merger,
reorganization or liquidation, involving the Issuer or any of its subsidiaries;

         (c) A sale or transfer of a material  amount of assets of the Issuer or
any of its subsidiaries;

         (d) Any change in the present  board of directors or  management of the
Issuer,  including  any  plans or  proposals  to  change  the  number or term of
directors or to fill any existing vacancies on the board;

         (e) Any  material  change in the  present  capitalization  or  dividend
policy of the Issuer;

         (f) Any other  material  change in the  Issuer's  business or corporate
structure;

         (g)   Changes  in  the   Issuer's   charter,   bylaws  or   instruments
corresponding  thereto or other  actions  which may impede  the  acquisition  of
control of the Issuer by any person;

         (h) Causing a class of  securities  of the Issuer to be delisted from a
national  securities  exchange or to cease to be  authorized  to be quoted in an
inter-dealer quotation system of a registered national securities association;

         (i) A class of equity  securities of the Issuer  becoming  eligible for
termination  of  registration  pursuant to Section  12(g)(4)  of the  Securities
Exchange Act of 1934, as amended, or

         (j) Any action similar to any of those enumerated above.

         Continental  has  recently  announced  that  it  has  entered  into  an
agreement  pursuant  to which it will  merge  with and into U S WEST,  Inc.  The
Department  of Justice and  Continental  are  currently  engaged in  discussions
regarding  such merger and, as a result,  Continental  may be required to divest
its  interest  in the Issuer  within a time frame to be agreed  upon,  but which
would not be earlier than June 30, 1997.

         Although  directors of the Issuer who are also  directors,  officers or
employees  of the Filing  Persons  or any of their  respective  affiliates  have
certain  fiduciary  obligations to the Issuer under Delaware law, such directors
and the Filing Persons,  as the controlling  stockholders of the Issuer,  are in
positions that may create conflicts of interest with respect to certain business

CUSIP No. 879463 107                                        Page 14 of 18 Pages


opportunities  available to and certain  transactions  involving the Issuer. The
Filing Persons have not adopted any special voting  procedures to deal with such
conflicts of interest and there can be no assurance  that any such conflict will
be resolved in favor of the Issuer.  In this regard,  the  Issuer's  Amended and
Restated  Certificate of Incorporation  provides that the Issuer may not provide
certain (i) wireless  communications  services (other than products and services
delivered via  point-to-point  microwave and  milliwave  transmissions)  or (ii)
telecommunications  services to residences  until,  in each case, the earlier of
the date  that is five  years  after  the  filing of its  Amended  and  Restated
Certificate of  Incorporation or the date on which the holders of Class B Common
Stock no longer  represent at least 50% of the voting  power of the  outstanding
Common Stock of the Company,  without the  affirmative  vote of the holders of a
majority of the Class B Common Stock, subject to certain exceptions.

         As  described  in Item 6 below,  pursuant to the Amended  Stockholders'
Agreement,  a holder of Class B Common Stock  generally is entitled to designate
one  director  nominee for each 9% of the  outstanding  shares of Class B Common
Stock held by it and its affiliates.  The holders of the Class A Common Stock do
not  have the  right,  as a class,  under  the  Issuer's  Amended  and  Restated
Certificate of Incorporation or the Amended Stockholders'  Agreement to nominate
any individuals for election to the Board of Directors. Three current members of
the Board of  Directors  are the  designees  of Cox,  three such members are the
designees of TCI and two are designees of Comcast. In addition,  each of Cox and
TCI has the right to and will designate an additional director.

         Affiliates of TCI, Cox and Comcast, which collectively will designate a
majority of the  directors of the Issuer,  together  with an affiliate of Sprint
Corporation  ("Sprint"),  have formed Sprint Spectrum,  a partnership created to
provide certain wireless  telecommunications  services.  The investments by TCI,
Cox and  Comcast  in Sprint  Spectrum  and in the  Issuer  may  encourage  these
companies to promote  arrangements  between the Issuer and Sprint  Spectrum.  As
recently as January  1996,  TCI, Cox and Comcast  expressed  their  intention to
attempt to  integrate  the  business of the Issuer  with the  business of Sprint
Spectrum.  At present,  TCI,  Cox and Comcast  are not in any  discussions  with
Sprint or Sprint Spectrum with respect to the Issuer.

         Except as otherwise disclosed in this Report, no Filing Person has made
any decision  concerning its course of action with respect to the Issuer. Any of
the Filing  Persons  could  decide,  depending on market and other  factors,  to
dispose of shares of the  Issuer's  Common  Stock  beneficially  owned by it, to
acquire  additional  Common Stock or other equity  securities of the Issuer,  to
seek a strategic or other partner to share its interest in the Issuer or to take
any other available course of action. In this regard, each of the Filing Persons
intends to  continuously  review its  investment in the Issuer.  In reaching any
conclusion as to its future course of action,  each Filing Person will take into
consideration  various  factors,   including  without  limitation  the  Issuer's
business and financial  condition and prospects,  other developments  concerning
the Issuer,  the effect of legal and regulatory  requirements  applicable to the
Issuer and the Filing  Person,  other  business  opportunities  available to the
Filing Person,  developments  with respect of the business of the Filing Person,
developments  in  the  cable   television  and   telecommunications   industries
generally, general economic conditions and money and stock market conditions.

Item 5.  Interest in securities of the issuer.

         (a) The following table  indicates,  with respect to each Filing Person
and the  Filing  Persons  collectively  as a group,  (i) the number of shares of
Class A Common  Stock  currently  owned,  (ii) the  number  of shares of Class A
Common Stock that may be acquired  within 60 days as a result of the  conversion
on a one for one basis of shares of Class B Common Stock currently owned,  (iii)
the total number of shares of Class A Common  Stock owned,  treating the Class B
Common Stock  currently  owned as if it had been  converted  into Class A Common
Stock, and (iv) the percentage of Class A Common Stock  represented by the total
number of  shares of Class A Common  Stock  owned,  treating  the Class B Common
Stock as if it had been  converted  into Class A Common  Stock.  The  percentage
ownership for the Filing  Persons as a group assumes the conversion of shares of
Class B Common Stock into Class A Common Stock by all members of the group.  The
percentage  ownership  for each Filing  Person  assumes  conversion by only that
stockholder.  As a group,  the Filing Persons control  approximately  98% of the

due to the  existence  of  the  voting  arrangements  contained  in the  Amended

existence of the restrictions on transfer contained in the Amended Stockholders'

Item 6.  Contracts, arrangements, understandings or relationships
             with respect to securities of the issuer.

         Wholly owned  subsidiaries of each of the Filing Persons and the Issuer
are parties to an Amended and Restated Stockholders'  Agreement dated as of June
26, 1996 (the  "Amended  Stockholders'  Agreement").  The Amended  Stockholders'
Agreement  provides that at each annual meeting of the Issuer's  stockholders at
which  directors are elected,  the holders of the Class B Common Stock will vote
their  shares  of  Class A Common  Stock  and  Class B Common  Stock in favor of
nominees for directors to be  designated as follows:  (i) the holders of Class B
Common Stock will  designate ten nominees (with the right of a holder of Class B

Common Stock to designate  one or more nominees  depending on the  percentage of
the Class B Common Stock held by it),  (ii) the Board of Directors of the Issuer
will designate by unanimous consent the Chief Executive Officer of the Issuer as
a nominee and (iii) the Board of Directors  with the  unanimous  approval of the
holders of Class B Common  Stock that have the right to  designate  nominees for
director  shall  designate  two  individuals  who are  neither  employed  by nor
affiliated with the Issuer or any holder of Class B Common Stock as nominees for
director.  Under the Amended Stockholders' Agreement, a holder of Class B Common
Stock generally is entitled to designate one director nominee for each 9% of the
outstanding  shares of Class B Common Stock held by it and its  affiliates.  The
holders of the Class A Common Stock do not have the right, as a class, under the
Issuer's  Amended  and  Restated  Certificate  of  Incorporation  or the Amended
Stockholders' Agreement to nominate any individuals for election to the Board of
Directors.  Three current members of the Board of Directors are the designees of
Cox,  three such  members  are the  designees  of TCI and two are  designees  of
Comcast. In addition, each of Cox and TCI has the right to and will designate an
additional director.  Continental does not currently have any right to designate
a director.

         The Amended  Stockholders'  Agreement prohibits any transfer of Class B
Common Stock held by the parties thereto,  unless expressly  permitted under the
terms  thereof.  Parties to the Amended  Stockholders'  Agreement  have  certain
rights of first offer and rights of first  refusal  thereunder  with  respect to
proposed sales of the Class B Common Stock.

         Each holder of Class B Common Stock has the right to sell all or a part
of  its  Class  B  Common  Stock  upon  receiving  a bona  fide  offer  from  an
unaffiliated third party, subject to giving notice to the other holders of Class
B Common Stock who have  designated  at least one  director,  which notice shall
contain  an offer to sell such  stock to such  other  holders  of Class B Common
Stock on the terms and  conditions  set forth in the offer from the third party.
Subject to certain limitations,  the non-selling holders of Class B Common Stock
have the right to purchase  pro rata all,  but not less than all, of the Class B
Common Stock offered.  If the non-selling holders of Class B Common Stock do not
purchase all of the Class B Common Stock offered,  the offering holders of Class
B Common Stock may sell the Class B Common Stock to the third party on the terms
contained  in the  offer  made to the  other  holders  of Class B Common  Stock.
However,  unless the amount of Class B Common Stock is sufficient to entitle the
transferee to designate a nominee for director  under the Amended  Stockholders'
Agreement (i.e., the total percentage of Class B Common Stock that would be held
by the  transferee  and certain of its  affiliates is at least nine percent) and
the transferee agrees to become a party to the Amended Stockholders'  Agreement,
any Class B Common  Stock  included in the stock being sold must be converted to
Class A Common Stock.

         If any party  desires to convert Class B Common Stock to Class A Common
Stock,  it must first  offer  that stock to the other  holders of Class B Common
Stock who have  designated at least one  director.  If such other holders do not
elect to buy such  stock,  then such  stock can be  converted  to Class A Common
Stock and sold by the selling stockholder free of restrictions under the Amended
Stockholders' Agreement.

         The  parties  to  the  Amended  Stockholders'   Agreement  have  demand
registration  rights on the following  terms:  (i) no demand may be made for the
first six months after the  Offering,  (ii) such parties  collectively  have the
right to make one demand per year (with any such party  having the right to make
such  demand),  (iii) the amount which can be sold pursuant to any demand may be
limited if the managing  underwriter selected by the Issuer with the approval of
the party to the Amended  Stockholders'  Agreement that has included the largest
number of shares in the registration  advises the Issuer that marketing  factors
require a limitation of the number of shares to be underwritten  and (iv) if the
amount  determined  pursuant to clause (iii) is less than the  aggregate  amount
which such parties want to sell in such offering,  each such party will have the
right to sell its pro rata  portion of the maximum  amount;  provided,  however,
that  during  the period  ending 42 months  after the date of the  Offering,  if
Continental  is subject to a  regulatory  requirement  as a result of its merger
with U S WEST,  Inc.  to reduce  or  eliminate  its  investment  in the  Issuer,
Continental  will have a priority  claim in specified  percentages on the amount
specified in clause  (iii) above and the balance  will be split  proportionately
among the other  stockholders  which  are a party to the  Amended  Stockholders'
Agreement.  The parties to the Amended Stockholders'  Agreement participating in

the  registration  must  reimburse  the  Issuer for its  out-of-pocket  expenses
incurred  in  connection  with  any  such  demand   registration.   The  Amended
Stockholders  Agreement will  terminate  when the aggregate  voting power of the
Class B Common Stock  represents less than 30% of the aggregate  voting power of
all outstanding Common Stock.

Agreement  contained  herein is  qualified  in its  entirety by reference to the

          (a) Any  agreement  by a  Consenting  Stockholder  herein  to vote its
shares of Common Stock in a certain manner shall be deemed, in each instance, to
include an agreement by that  Consenting  Stockholder to use its best efforts to
take all actions  necessary  to call,  or cause the Company and the  appropriate

special meeting of stockholders or to act by written consent.

          (b)  When  any  action  is  required  to  be  taken  by  a  Consenting
Stockholder pursuant to this Agreement,  such Consenting  Stockholder shall take

SECTION 2 BOARD OF DIRECTORS AND STOCKHOLDERS

          2.1 Composition of the Board.

               (a) The Board shall consist of thirteen directors. Individuals to
serve on the Board shall be  nominated in  accordance  with this  Agreement  and
nomination  procedures  established by the Board, the Company's  By-Laws and the
rules  and   regulations  of  the  SEC  and  the  principal  stock  exchange  or
association,  if any, on which the Common  Stock is listed.  Directors  shall be
elected in  accordance  with the  Company's  Certificate  of  Incorporation  and
By-Laws and the General Corporation Law of Delaware.

               (b) No  Consenting  Stockholder  shall  nominate  or vote for any
individual to serve as a director of the Company except an individual designated
pursuant to the  provisions of this Section  2.1(b) or Section 2.3. A Consenting
Stockholder may nominate for election as a director any individual designated by
such Consenting Stockholder pursuant to Section 2.1(b)(i), Section 2.1(b)(iv) or
Section 2.3 or any individual  designated  pursuant to Section 2.1(b)(ii) if, in
any such case,  such  individual was not duly nominated in connection  with such
election by the Board or a  nominating  committee  of the Board  pursuant to the
Company's nomination  procedures.  Each Consenting  Stockholder hereby agrees to
vote all shares of Common Stock owned by such  Consenting  Stockholder  to cause
the election to the Board of the individuals  designated in accordance with this
Section  2.1(b) and Section 2.3. For purposes of this  Agreement,  an individual
designated  in accordance  with this Section  2.1(b) or Section 2.3 to which the
foregoing covenants in this Section

                                      - 7 -

2.1(b)  apply is  referred  to as an  "Agreed  Nominee."  For  purposes  of this
Agreement,  each  Consenting  Stockholder  none of the Controlled  Affiliates of
which is also a Consenting  Stockholder and each group of two or more Consenting
Stockholders  that are  Controlled  Affiliates of each other shall  constitute a
"Consenting Stockholder Group."

                    (i) Subject to Section 2.1(c),  each Consenting  Stockholder
Group shall have the right to designate a number of Agreed Nominees equal to the
largest  integer that is less than or equal to its  Adjusted  Class B Percentage
divided by nine percent.  A Consenting  Stockholder  Group's  "Adjusted  Class B
Percentage"  equals  the  number,  designated  as a  percentage,  determined  by
dividing  (x) the  aggregate  number of shares of Class B Common  Stock owned by
such Consenting Stockholder Group by (y) the aggregate number of shares of Class
B Common Stock  outstanding  (but  excluding  all shares of Class B Common Stock
owned by Continental and its Controlled Affiliates if the Consenting Stockholder
Group that includes Continental is not at such time entitled to designate one or
more Agreed Nominees pursuant to Section 2.1(c));

                    (ii) The CEO shall be an Agreed Nominee;

                    (iii) Two individuals nominated by the Board or a nominating
committee of the Board to be Independent  Directors  shall be Agreed Nominees if
(A) such  individuals  were  nominated  by the  Board and all  individuals  then
serving on the Board who were  Agreed  Nominees  pursuant  to Section  2.1(b)(i)
voted  for  their  nomination  or  (B)  such  individuals  were  nominated  by a
nominating  committee  of the Board,  the  members of the  nominating  committee
included at least one Agreed Nominee  previously  designated by each  Consenting
Stockholder  Group  pursuant  to  Section  2.1(b)(i)  and  each  member  of  the
nominating  committee who was an Agreed  Nominee  pursuant to Section  2.1(b)(i)
voted for their nomination;  as used herein,  an "Independent  Director" means a
director  who is neither  employed  by nor  affiliated  with the  Company or any
Consenting Stockholder; and

                    (iv) If the  number of  Agreed  Nominees  designated  by the
Consenting  Stockholder Groups pursuant to Section 2.1(b)(i) and pursuant to any
prior  application  of this Section  2.1(b)(iv) is less than ten, the Consenting
Stockholder Group (other than (A) the Consenting Stockholder Group that includes
Continental if such Consenting Stockholder Group is not entitled to designate an
Agreed  Nominee as a result of Section  2.1(c) and (B) a Consenting  Stockholder
Group  that  designated  an  additional  Agreed  Nominee  pursuant  to  a  prior
application of this Section  2.1(b)(iv))  that then has the smallest  difference
between its Adjusted Class B Percentage and the next highest  integral  multiple
of 9% shall designate an additional Agreed Nominee.

               (c)  After  the  earlier  to occur of a Public  Offering  and the
consummation of the U S West Transaction,  the Consenting Stockholder Group that
includes  Continental  shall only be  entitled to  designate  one or more Agreed
Nominees pursuant to Section 2.1(b) if:

                    (i) no Affiliate of Continental is a local exchange carrier;

                    (ii) the Company  shall have  received an opinion from a law
firm  reasonably   acceptable  to  the  Consenting   Stockholders   (other  than
Continental) to the effect that such Consenting  Stockholder Group's designation
of an Agreed  Nominee  and such  person's  serving as a director  of the Company
would not violate any law, rule or  regulation or any order,  award or decree of
any governmental body or administrative  authority,  including the Department of
Justice; and

                    (iii) a majority of the Board (excluding any director of the
Company who was an Agreed Nominee designated by the Consenting Stockholder Group
that  includes  Continental)   approves  such  Consenting   Stockholder  Group's
designation of one or more Agreed  Nominees in accordance with the provisions of
Section 2.1(b).

               (d) The Consenting  Stockholder Groups shall initially  designate
Agreed Nominees and the Consenting Stockholders shall cause such Agreed Nominees
to be elected as directors promptly following the date hereof to serve until the
next  annual  meeting  of the  stockholders  of  the  Company.  Thereafter,  the
Consenting  Stockholder  Groups shall  designate  Agreed  Nominees prior to each
annual meeting of the stockholders of the Company in a manner that is consistent
with the Company's  nomination  procedures and the rules and  regulations of the
SEC and the principal stock exchange or association, if any, on which the Common
Stock is listed.

          2.2 Removal of Directors.

               (a) Each Consenting  Stockholder  shall vote all shares of Common
Stock owned by it for the removal  (with or without  cause) of any  director who
was an Agreed Nominee  designated by a Consenting  Stockholder Group pursuant to
Section  2.1(b)(i),  Section  2.1(b)(iv)  or  Section  2.3(c) if the  Consenting
Stockholder  Group that so  designated  such Agreed  Nominee (i)  requests  such
removal by notice to the other  Consenting  Stockholders,  (ii) ceases to hold a
number  of  shares  of  Class  B  Common  Stock  that  entitle  such  Consenting
Stockholder  Group  to  designate  the  number  of  Agreed  Nominees  previously
designated  by such  Consenting  Stockholder  Group  pursuant to Section  2.1(b)
(except  that,  upon any such  reduction  in its  ownership of shares of Class B
Common Stock, such Consenting Stockholder Group shall

                                      - 9 -


<PAGE>



be  entitled  to  identify a number of such  directors  who shall not be removed
pursuant to this clause  (ii) equal to the number of Agreed  Nominees  that such
Consenting  Stockholder  is then  entitled  to  designate  pursuant  to  Section
2.1(b)(i) and Section  2.1(b)(iv)),  or (iii) is no longer entitled to designate
any Agreed Nominees pursuant to Section 2.1(c).

               (b) Each Consenting  Stockholder  shall vote all shares of Common
Stock  owned by it for the  removal  of an  individual  designated  as an Agreed
Nominee pursuant to Section  2.1(b)(ii) and thereafter  elected as a director if
such individual ceases to serve as CEO for any reason.

               (c) An Independent Director may be removed in accordance with the
Company's Certificate of Incorporation and By-laws.

          2.3  Vacancies.  If,  as a result of  death,  disability,  retirement,
resignation,  removal (with or without cause) or otherwise  there shall exist or
occur any vacancies on the Board,  individuals to fill such  vacancies  shall be
nominated  and  elected  in the manner  provided  in this  Agreement  and in the
Company's Certificate of Incorporation and By-laws. Agreed Nominees with respect
to an election to fill any such vacancies shall be designated as follows:

               (a) in the case of the CEO, the  successor CEO shall be an Agreed
Nominee;

               (b)  in  the  case  of an  Independent  Director,  an  individual
nominated in the manner described in Section 2.1(b)(iii); and

               (c) in all other cases,  by the Consenting  Stockholder  Group or
Consenting  Stockholder  Groups that,  under  Section 2.1, are then  entitled to
designate  a greater  number of Agreed  Nominees  than the  number of  directors
currently  sitting  on the  Board who are  Agreed  Nominees  designated  by such
Consenting   Stockholder  Group  (by  each  such  Consenting  Stockholder  Group
according to the number of additional  Agreed Nominees that each such Consenting
Stockholder Group is so entitled to designate).

          2.4  Conflicting   Charter  or  By-law  Provisions.   Each  Consenting
Stockholder  shall  vote its  shares of Common  Stock,  and shall take all other
actions necessary, to ensure that the Company's Certificate of Incorporation and
By-laws  facilitate  and do not at any time conflict with the provisions of this
Agreement.

assign, grant a participation in or option with respect to, pledge,  encumber or

Class B Common Stock  except in a  transaction  that is  expressly  permitted by
Section 3.3 or in compliance  with Section 3.4, 3.5 or 3.6, as  applicable.  Any
attempt to sell,  transfer,  assign,  grant a  participation  in or option  with
respect  to,  pledge,  encumber or  otherwise  dispose of, or convert to Class A
Common  Stock,  any  shares  of Class B Common  Stock in a manner  that does not
comply with this Agreement shall be ineffective.

               (b) Except as expressly  permitted or required by this Agreement,
(i) each Consenting Stockholder shall be the record and beneficial owner of such
shares of Class B Common Stock indicated in the Company's records as being owned
by such Consenting Stockholder, in each case free and clear of any pledge, lien,
security interest, charge, claim, equity, option or encumbrance of any kind, and
(ii) no Consenting  Stockholder  shall enter into any  agreement or  arrangement
with respect to the exercise of its rights to  designate  Agreed  Nominees or to
request the  removal of a director  pursuant  to this  Agreement  (other than an
agreement or arrangement solely among Consenting  Stockholders that are included
in the same Consenting Stockholder Group); provided, however, that the foregoing
shall not be construed to limit the ability of a Consenting Stockholder to enter
into agreements with respect to the voting of its shares of Common Stock pending
a sale of such stock permitted by Section 3.1(a) or to enter into agreements not
inconsistent  with this  Agreement that restrict such  Consenting  Stockholder's
ability to transfer shares of Class B Common Stock.

               (c) Each Consenting  Stockholder agrees that no Indirect Transfer
shall occur with respect to such Consenting Stockholder except for:

                    (i) an  Indirect  Transfer  in  connection  with the sale or
other  disposition to the transferee or its Controlled  Affiliate  (including by

               (d) a transfer by TCI Teleport,  Inc. of shares of Class B Common
Stock to the Company pursuant to Section 3.4 of the Reorganization Agreement.

          3.4 Conversion of Class B Common Stock to Class A Common Stock;  Right
of First Offer.

               (a) Except as expressly  permitted  pursuant to Section 3.5(c) or
Section  3.6,  no  Consenting  Stockholder  shall  convert any shares of Class B
Common Stock to Class A Common Stock prior to the  consummation of the Company's
initial Public Offering.  After the consummation of the Company's initial Public
Offering,  if a Consenting  Stockholder (a "Converting  Stockholder") desires to
convert  all or any  portion  of its  shares of Class B Common  Stock to Class A
Common  Stock,  it shall first deliver to each other  Designating  Stockholder a
written  notice (a "First Offer Notice of Sale") of its  intention to so convert
such shares of Class B Common Stock (the "First Offer  Shares").  The Converting
Stockholder shall not convert any of its shares of Class B Common Stock to Class
A Common  Stock  unless and until it has  delivered a First Offer Notice of Sale
with respect to such shares to such other Designating  Stockholders  pursuant to
this Section 3.4 and otherwise  complied with the provisions of this Section 3.4
(except as expressly  permitted  pursuant to Section 3.5(c) or Section 3.6). The
First Offer Notice of Sale shall contain the Converting  Stockholder's  offer to
sell the First Offer Shares to such other  Designating  Stockholders  at a price
per share equal to the Market  Price as of the date of the First Offer Notice of
Sale (which price shall,  unless otherwise agreed by the Converting  Stockholder
and the Designating  Stockholders  accepting such offer, be payable in cash). As
used in this  Section 3.4,  the  "Qualifying  First Offer  Amount"  means,  with
respect to any First  Offer  Notice of Sale,  the  amount,  if any, by which the
number of First  Offer  Shares  specified  in such  First  Offer  Notice of Sale
exceeds two percent of the number of shares of Common Stock  outstanding  at the
time such First Offer Notice of Sale is delivered  (or such lesser amount as may
be specified in the First Offer Notice of Sale or as may  otherwise be agreed to
by the Converting Stockholder).

                    (i) If a  Designating  Stockholder  desires to accept all or
any  portion  of the  offer  set forth in a First  Offer  Notice  of Sale,  such
Designating Stockholder (a "First Offer Electing Stockholder") shall, within ten
Business  Days of  receipt  of such  First  Offer  Notice  of Sale,  notify  the
Converting  Stockholder  of its  intention to acquire First Offer Shares and the
number of such shares it desires to  acquire,  and deliver a copy of such notice
to each other Designating Stockholder.

                    (ii) If, after giving  effect to any  amendment to any First
Offer Electing Stockholder's notice

                                     - 13 -

pursuant to Section 3.4(a)(iii), the First Offer Electing Stockholders desire to
acquire,  in the  aggregate,  either (x) all the First  Offer  Shares,  or (y) a
number of First Offer  Shares that is not more than the  Qualifying  First Offer
Amount,  then the First  Offer  Electing  Stockholders  shall  have the right to
acquire,  in the case of clause (x),  all the First Offer Shares or, in the case
of clause (y), the number of shares that the First Offer  Electing  Stockholders
desire to acquire (such shares that the First Offer Electing  Stockholders  have
the right to acquire, the "Allocable First Offer Shares"),  allocated among them
as follows (or in such other manner as the First Offer Electing Stockholders may
agree):

                         (A) the Allocable First Offer Shares shall be allocated
among the First  Offer  Electing  Stockholders  pro rata (based on the number of
shares of Class B Common Stock owned by each of them) until all of the Allocable
First Offer Shares have been allocated or any First Offer  Electing  Stockholder
has been  allocated the number of First Offer Shares that it desires to acquire,
as specified in its notice to the  Converting  Stockholder,  as it may have been
amended pursuant to Section 3.4(a)(iii);

                         (B)  if  all  Allocable  First  Offer  Shares  are  not
allocated  pursuant to paragraph (A) or any prior  application of this paragraph
(B),  any  Allocable  First  Offer  Shares that were not  allocated  pursuant to
paragraph (A) or any prior  application of this paragraph (B) shall be allocated
among the First Offer Electing Stockholders (other than any First Offer Electing
Stockholder  that has been  allocated  the number of First Offer  Shares that it
desires to acquire, as specified in its notice to the Converting Stockholder, as
it may have been amended pursuant to Section 3.4(a)(iii)) pro rata (based on the
number of shares of Class B Common Stock owned by each of them); and

                         (C)  if  all  Allocable  First  Offer  Shares  are  not
allocated  pursuant to paragraph (A) and any prior application of paragraph (B),
any Allocable  First Offer Shares that were not allocated  pursuant to paragraph
(A) and any prior  application of paragraph (B) shall be allocated by continuing
to apply paragraph (B) as required.

                    (iii) If the First  Offer  Electing  Stockholders  desire to
acquire,  in the  aggregate,  less than all of the First Offer Shares,  then the
Converting  Stockholder  shall so notify the First Offer  Electing  Stockholders
and:

                         (A) subject to Section 3.4(a)(iii)(B), each First Offer
Electing  Stockholder  shall  have the  right,  by  written  notice  sent to the
Converting  Stockholder  (with a copy of such  notice to each other  Designating
Stockholder)  within  five  days  after  its  receipt  of the  notice  from  the
Converting

Stockholder  pursuant  to this  Section  3.4(a)(iii)  to  amend  the  notice  it
delivered  pursuant to  3.4(a)(i)  to  increase or decrease  the number of First
Offer Shares that it desires to purchase;

                         (B) notwithstanding Section  3.4(a)(iii)(A),  no notice
by any First Offer  Electing  Stockholder  pursuant to this Section  3.4(a)(iii)
shall  constitute an amendment of the notice it delivered  pursuant to 3.4(a)(i)
if the number of shares that the First Offer  Electing  Stockholders  originally
desired to acquire, in the aggregate,  as specified in their notices pursuant to
3.4(a)(i)  was less than or equal to the  Qualifying  First Offer Amount and the
number of shares that the First Offer Electing Stockholders subsequently desired
to acquire,  in the  aggregate,  as specified in their notices as proposed to be
amended  pursuant to this Section  3.4(a)(iii),  was greater than the Qualifying
First Offer  Amount but less than all the First Offer  Shares;  if this  Section
3.4(a)(iii)(B)  applies,  the First Offer Electing  Stockholders  shall have the
right to acquire the number of shares that the First Offer Electing Stockholders
originally  desired to acquire,  allocated among them in accordance with Section
3.4(a)(ii);

                         (C) if,  after  giving  effect to any  amendment to any
First Offer Electing  Stockholder's notice pursuant to this Section 3.4(a)(iii),
the First  Offer  Electing  Stockholders  desire to acquire,  in the  aggregate,
either (x) all the First Offer  Shares,  or (y) a number of First  Offer  Shares
that is not more than the  Qualifying  First Offer Amount,  then the First Offer
Electing  Stockholders  shall have the right to  acquire,  in the case of clause
(x),  all the First Offer  Shares or, in the case of clause  (y),  the number of
shares that the First Offer Electing  Stockholders desire to acquire,  allocated
among them in accordance with Section 3.4(a)(ii);

                         (D) if,  after  giving  effect to any  amendment to any
First Offer Electing  Stockholder's  notice pursuant to this Section 3.4(a)(iii)
(but subject to Section  3.4(a)(iii)(B)),  the First Offer Electing Stockholders
desire to acquire,  in the  aggregate,  a number of First  Offer  Shares that is
greater than the Qualifying First Offer Amount but less than all the First Offer
Shares, then the Converting  Stockholder's offer of the First Offer Shares shall
be  deemed  rejected  in full as of the  last  day  for a First  Offer  Electing
Stockholder to amend its notice pursuant to this Section 3.4(a)(iii); and

                         (E) if,  after  giving  effect to any  amendment to any
First Offer Electing  Stockholder's notice pursuant to this Section 3.4(a)(iii),
the First Offer Electing  Stockholders  desire to acquire,  in the aggregate,  a
number of First Offer Shares that is less than or equal to the Qualifying  First
Offer Amount, then the Converting  Stockholder's offer of the First Offer Shares
shall be deemed accepted as to the number

                                     - 15 -


<PAGE>



of First  Offer  Shares  that the First Offer  Electing  Stockholders  desire to
acquire  (and the First  Offer  Electing  Stockholders  shall  have the right to
acquire such shares as provided in Section  3.4(a)(iii)(C))  and shall be deemed
rejected with respect to that portion of the First Offer Shares that exceeds the
number of First Offer Shares that the First Offer Electing  Stockholders  desire
to acquire as of the last day for a First Offer  Electing  Stockholder  to amend
its notice pursuant to this Section 3.4(a)(iii).

                    (iv)   Notwithstanding  the  foregoing  provisions  of  this
Section  3.4(a),  the allocation of Allocable First Offer Shares among the First
Offer Electing Stockholders shall be subject to Section 3.7(a).

               (b) If (i) the Converting  Stockholder's offer of the First Offer
Shares is rejected (in whole or in part) as provided in Section 3.4(a),  or (ii)
the purchase of the First Offer Shares is not consummated  within the period set
forth in Section  3.7(b) for any  reason  other than a breach by the  Converting
Stockholder of any of its covenants,  representations  or warranties  that are a
condition to consummation of such purchase, then, beginning on the date that the
Converting  Stockholder's  offer of the First Offer Shares is deemed rejected or
the day  following  the last day of the period set forth in Section  3.7(b),  as
applicable (such applicable date, the "Free- to-Convert  Date"),  the Converting
Stockholder  shall have the right to convert the First Offer Shares with respect
to which the  Converting  Stockholder's  offer was  rejected  or the First Offer
Shares that were not purchased within the period set forth in Section 3.7(b), as
applicable (such First Offer Shares, the "Free-to-Convert Shares"), to shares of
Class A Common  Stock at any time  prior to the later of (i) the  ninetieth  day
after the Free-to-Convert  Date, or (ii) if prior to or within ten Business Days
after the  Free-to-Convert  Date the Converting  Stockholder  either  delivers a
Demand Notice  pursuant to Section 4.1 or submits a written  request in response
to a Company Notice pursuant to Section 4.1 with respect to the  registration of
the shares of Class A Common Stock into which the Free-to-Convert  Shares may be
converted,  either (A) the date on which the registration statement filed by the
Company with respect to such shares of Class A Common Stock becomes effective or
(B) the date on which such registration  statement is withdrawn,  as applicable.
If the Converting  Stockholder does not convert the Free-to- Convert Shares into
shares Class A Common Stock during the  applicable  period,  the  procedure  set
forth  above with  respect to the First  Offer  Notice of Sale shall be repeated
with respect to any subsequent  proposed  conversion of shares of Class B Common
Stock to shares of Class A Common Stock by the Converting Stockholder.

          3.5 Right of First Refusal.

               (a) If a Consenting  Stockholder (a "Selling Stockholder") or its
Parent or other Controlled Affiliate shall receive at any time a bona fide offer
in writing,  which the  Selling  Stockholder  or its Parent or other  Controlled
Affiliate  proposes to accept (a "Third Party  Offer"),  from a third party (the
"Third  Party  Offeror")  to acquire all or part of its shares of Class B Common
Stock (the "First Refusal  Shares") or to effect an Indirect  Transfer (in which
case the "First Refusal  Shares" shall be all the shares of Class B Common Stock
owned by the Selling Stockholder), the Selling Stockholder shall deliver to each
other  Designating  Stockholder  (the "First Refusal  Stockholders") a notice (a
"First Refusal Notice of Sale")  containing a copy of the Third Party Offer, the
identity  of the Third  Party  Offeror  and an offer to sell the  First  Refusal
Shares to the First  Refusal  Stockholders  on the following  terms:  (i) if the
Third Party Offer  contemplates  a purchase of the First  Refusal  Shares by the
Third  Party  Offeror  for  consideration  consisting  solely of cash,  then the
Selling  Stockholder's  offer shall be to sell the First Refusal Shares for cash
in an amount  equal to the purchase  price  specified  in, and  otherwise on the
terms and conditions  contained in, the Third Party Offer, and (ii) if the Third
Party Offer contemplates an acquisition of the First Refusal Shares by the Third
Party Offeror for consideration any portion of which is not cash or if the Third
Party Offer  contemplates an Indirect Transfer,  then the Selling  Stockholder's
offer shall be to sell the First  Refusal  Shares for cash in an amount equal to
the fair market value of the First  Refusal  Shares (as  determined  pursuant to
Section 3.5(d)) and otherwise on the terms and conditions contained in the Third
Party Offer.  The First Refusal  Notice of Sale shall specify the price at which
the First Refusal Shares are offered, as provided in the preceding sentence.  No
Consenting  Stockholder  shall  sell or assign,  or offer to sell or assign,  or
otherwise  dispose of any of its shares of Class B Common  Stock  (other  than a
disposition  pursuant to Section 3.3, 3.4 or 3.6) or permit an Indirect Transfer
to occur with respect to such  Consenting  Stockholder  (other than  pursuant to
Section 3.1(c)(i)), unless and until such Consenting Stockholder has delivered a
First  Refusal  Notice of Sale with respect to such shares to the First  Refusal
Stockholders  pursuant  to this  Section  3.5 and  otherwise  complied  with the
provisions of this Section 3.5. The First Refusal  Stockholders shall enter into
an appropriate  confidentiality  agreement  reasonably  requested by the Selling
Stockholder with respect to the Third Party Offer.

                    (i) If a First Refusal  Stockholder desires to accept all or
any portion of the offer set forth in a First  Refusal  Notice of Sale as to any
part of the First  Refusal  Shares,  such First  Refusal  Stockholder  (a "First


                                     - 17 -


<PAGE>


Refusal  Electing  Stockholder")  shall,  within ten Business Days of receipt of
such  First  Refusal  Notice of Sale,  notify  the  Selling  Stockholder  of its
intention  to acquire  First  Refusal  Shares  and the number of such  shares it
desires  to  acquire,  and  deliver a copy of such  notice to each  other  First
Refusal Stockholder.

                    (ii) If the First Refusal  Electing  Stockholders  desire to
acquire,  in the  aggregate,  all of the First  Refusal  Shares,  then the First
Refusal  Electing  Stockholders  shall have the right to  acquire  all the First
Refusal Shares,  allocated among them as follows (or in such other manner as the
First Refusal Electing Stockholders may agree):

                         (A) the First Refusal  Shares shall be allocated  among
the First Refusal Electing  Stockholders pro rata (based on the number of shares
of Class B Common  Stock owned by each of them)  until all of the First  Refusal
Shares have been allocated or any First Refusal  Electing  Stockholder  has been
allocated  the number of First  Refusal  Shares that it desires to  acquire,  as
specified in its notice to the Selling Stockholder,  as it may have been amended
pursuant to Section 3.5(a)(iii);

                         (B) if all  First  Refusal  Shares  are  not  allocated
pursuant to paragraph (A) or any prior  application  of this  paragraph (B), any
First Refusal  Shares that were not  allocated  pursuant to paragraph (A) or any
prior  application  of this  paragraph  (B) shall be  allocated  among the First
Refusal Electing Stockholders (other than any First Refusal Electing Stockholder
that has been  allocated the number of First  Refusal  Shares that it desires to
acquire, as specified in its notice to the Selling  Stockholder,  as it may have
been amended  pursuant to Section  3.5(a)(iii)) pro rata (based on the number of
shares of Class B Common Stock owned by each of them); and

                         (C) if all  First  Refusal  Shares  are  not  allocated
pursuant to paragraph (A) and any prior  application of paragraph (B), any First
Refusal  Shares that were not allocated  pursuant to paragraph (A) and any prior
application of paragraph (B) shall be allocated by continuing to apply paragraph
(B) as required.

                    (iii) If the First Refusal Electing  Stockholders  desire to
acquire,  in the aggregate,  less than all of the First Refusal Shares, then the
Selling Stockholder shall so notify the First Refusal Electing Stockholders and:

                    (A) each First Refusal Electing  Stockholder  shall have the
right,  by written notice sent to the Selling  Stockholder  (with a copy of such
notice to each other Designating Stockholder) within five days after its receipt
of the notice from the Selling Stockholder pursuant to this Section

                                     - 18 -

3.5(a)(iii)  to amend its notice to increase the number of First Refusal  Shares
that it desires to purchase;

                    (B) if,  after giving  effect to any  amendment to any First
Refusal Electing Stockholder's notice pursuant to this Section 3.5(a)(iii),  the
First Refusal Electing Stockholders desire to acquire, in the aggregate,  all of
the First Refusal Shares,  then the First Refusal  Electing  Stockholders  shall
have the right to acquire all the First Refusal Shares,  allocated among them in
accordance with Section 3.5(a)(ii); and

                    (C) if,  after giving  effect to any  amendment to any First
Refusal Electing Stockholder's notice pursuant to this Section 3.5(a)(iii),  the
First Refusal Electing  Stockholders desire to acquire,  in the aggregate,  less
than all of the First Refusal Shares,  then the Selling  Stockholder's  offer of
the First Refusal Shares shall be deemed rejected as of the last day for a First
Refusal  Electing  Stockholder  to amend its  notice  pursuant  to this  Section
3.5(a)(iii).

                    (iv)   Notwithstanding  the  foregoing  provisions  of  this
Section  3.5(a),  the  allocation  of the First  Refusal  Shares among the First
Refusal Electing Stockholders shall be subject to Section 3.7(a).

               (b) If (i) the Selling  Stockholder's  offer of the First Refusal
Shares is rejected as provided in Section  3.5(a),  or (ii) the  purchase of the
First Refusal Shares is not  consummated  within the period set forth in Section
3.7(b) for any reason other than a breach by the Selling  Stockholder  of any of
its  covenants,   representations   or  warranties   that  are  a  condition  to
consummation  of such  purchase,  then the  Selling  Stockholder  shall have the
right,  at any time during the sixty-day  period  beginning on the date that the
Seller Stockholder's offer of the First Refusal Shares is deemed rejected or the
day  following  the last day of the  period  set  forth in  Section  3.7(b),  as
applicable,  to enter into a binding  agreement to sell all of the First Refusal
Shares  to  the  Third  Party  Offeror,  or  to  effect  the  Indirect  Transfer
contemplated  by the Third Party Offer,  as applicable,  in either case on terms
and  conditions no less  favorable in the  aggregate to the Selling  Stockholder
(and, in the case of an Indirect  Transfer,  its Parent) than those set forth in
the Third Party Offer, and thereafter (within the period specified below in this
Section  3.5(b))  to sell all of the First  Refusal  Shares  to the Third  Party
Offeror  or effect  the  Indirect  Transfer,  as  applicable,  pursuant  to such
agreement.  The Selling  Stockholder shall, as promptly as practicable and prior
to the closing of such sale or Indirect  Transfer,  provide to the First Refusal
Stockholders a copy of the agreement for the sale of the First Refusal Shares so
as to permit the First Refusal  Stockholders  to confirm for themselves that the


                                     - 19 -


<PAGE>


terms and conditions of such sale are not less favorable in the aggregate to the
Selling Stockholder (and, in the case of an Indirect Transfer,  its Parent) than
those set forth in the Third Party Offer.  If the Selling  Stockholder  does not
enter into such an agreement during such sixty-day period, or does not close the
sale thereunder within the period provided in Section 3.7(b),  the procedure set
forth above with respect to the First  Refusal  Notice of Sale shall be repeated
with respect to any subsequent proposed sale, assignment or other disposition of
shares of Common Stock by the Selling Stockholder.

               (c) If the First Refusal  Shares  include a sufficient  number of
shares of Class B Common  Stock to entitle the holder  thereof to  designate  at
least one Agreed Nominee under Section 2.1, then the Selling  Stockholder  shall
have the right to sell to the Third Party  Offeror such shares of Class B Common
Stock or permit the Indirect  Transfer,  as applicable,  without converting such
shares to Class A Common Stock so long as (i) in the case of a sale of the First
Refusal  Shares,  the Third Party Offeror assumes the obligations of the Selling
Stockholder under this Agreement and, if it is then in effect,  the Supplemental
Agreement with respect to such shares and becomes a party to this Agreement and,
if it is then in effect, the Supplemental Agreement,  and (ii) in the case of an
Indirect Transfer,  the Third Party Offeror,  upon taking control of the Selling
Stockholder, causes the Selling Stockholder to confirm in writing the continuing
validity and  effectiveness  of its  obligations  under this  Agreement  and the
Supplemental  Agreement. If the First Refusal Shares do not include a sufficient
number  of shares of Class B Common  Stock to  entitle  the  holder  thereof  to
designate at least one Agreed  Nominee  under Section 2.1, or if the Third Party
Offeror refuses to become a party to this Agreement or, if it is then in effect,
the  Supplemental  Agreement,  then  the  Selling  Stockholder  shall,  prior to
transferring  the First  Refusal  Shares to the Third Party Offeror or effecting
the Indirect Transfer, as applicable, convert all shares of Class B Common Stock
included in the First Refusal  Shares to Class A Common Stock and shall not have
the right to sell Class B Common  Stock to the Third Party  Offeror or to permit
the  Indirect  Transfer  while the Selling  Stockholder  holds shares of Class B
Common Stock. The conversion of shares of Class B Common Stock to Class A Common
Stock pursuant to the foregoing  sentence shall not be subject to the provisions
of Section 3.3, 3.4 or 3.6. If the Third Party  Offeror  receives only shares of
Class A Common  Stock,  then it shall not be  required to become a party to this
Agreement and shall not become a party to this  Agreement  except as provided in
the following sentence. If the Third Party Offeror receives only shares of Class
A Common Stock and such shares  represent at least five percent of the number of
shares of Common Stock then  outstanding,  then it shall have the right,  at its
option, to become a party to this Agreement.

               (d) Before  submitting a First Refusal Notice of Sale pursuant to
Section 3.5(a) in response to a Third Party Offer that  contemplates  (i) a sale
of  the  First  Refusal  Shares  in  conjunction  with  other  assets,  (ii)  an
acquisition  of  the  First  Refusal  Shares  by the  Third  Party  Offeror  for
consideration  any portion of which is not cash or (iii) an  Indirect  Transfer,
the Selling  Stockholder and the other Designating  Stockholders shall cause (A)
if the Third  Party Offer  contemplates  a sale of the First  Refusal  Shares in
conjunction with other assets,  the total  consideration  specified in the Third
Party  Offer to be  allocated  between the First  Refusal  Shares and such other
assets,  (B) if the Third Party Offer  contemplates  an acquisition of the First
Refusal Shares by the Third Party Offeror for consideration any portion of which
is not cash or if the Third Party Offer contemplates an Indirect  Transfer,  the
fair market value of the First  Refusal  Shares to be  determined,  in each case
pursuant to this Section 3.5(d):

                    (i) The  Selling  Stockholder  shall  deliver  to each other
Designating Stockholder a notice stating that the Selling Stockholder intends to
deliver a First Refusal  Notice of Sale to which this Section 3.5(d) applies and
identifying  an appraiser (the "First  Appraiser")  who has been retained by the
Selling Stockholder to allocate the total  consideration  specified in the Third
Party  Offer  or to  conduct  an  appraisal  of the  First  Refusal  Shares,  as
applicable,  pursuant to this Section 3.5(d). Within ten Business Days after its
receipt of the Selling  Stockholder's notice pursuant to the preceding sentence,
the Designating  Stockholder (other than the Selling Stockholder) that, together
with its Controlled  Affiliates,  owns the greatest  number of shares of Class B
Common  Stock,  shall  send a notice to the  Selling  Stockholder  and the other
Designating Stockholders identifying a second appraiser (the "Second Appraiser")
who shall be retained  by the Selling  Stockholder  to make such  allocation  or
conduct such appraisal, as applicable, pursuant to this Section 3.5(d).

                    (ii) The First  Appraiser  and the  Second  Appraiser  shall
submit their independent determinations of the amount of consideration allocable
to the First  Refusal  Shares  or the fair  market  value of the  First  Refusal
Shares,  as  applicable,  within  thirty days after the date on which the Second
Appraiser is retained.  If the respective  determinations of the First Appraiser
and  the  Second  Appraiser  vary  by  less  than  ten  percent  of  the  higher
determination, the amount of consideration allocable to the First Refusal Shares
or the fair  market  value of the  First  Refusal  Shares,  as  applicable,  for
purposes of Section 3.5(a), shall be the average of the two determinations.

                    (iii)  If  the  respective   determinations   of  the  First
Appraiser  and the Second  Appraiser  vary by ten  percent or more of the higher
determination, the two Appraisers shall promptly designate a third appraiser

                                     - 21 -


<PAGE>



(the "Third  Appraiser"),  who shall be retained by the Selling  Stockholder  to
make an allocation or conduct an appraisal  pursuant to this Section 3.5(d). The
First  Appraiser and the Second  Appraiser  shall be  instructed  not to, and no
party  to this  Agreement  or any  Controlled  Affiliate  of any  party  to this
Agreement  shall,  provide  any  information  to the Third  Appraiser  as to the
determinations  of the First  Appraiser  and the Second  Appraiser  or otherwise
influence the Third  Appraiser's  determination  in any way. The Third Appraiser
shall submit its  determination of the amount of consideration  allocable to the
First Refusal  Shares or the fair market value of the First Refusal  Shares,  as
applicable,  within  thirty days after the date on which the Third  Appraiser is
retained.  If a  Third  Appraiser  is  retained,  the  amount  of  consideration
allocable  to the First  Refusal  Shares or the fair  market  value of the First
Refusal Shares, as applicable,  for purposes of Section 3.5(a),  shall equal the
average of the two  closest of the three  determinations,  except  that,  if the
difference  between the highest and middle  determinations  is no more than 105%
and  no  less  than  95%  of  the  difference  between  the  middle  and  lowest
determinations,  then the amount of consideration allocable to the First Refusal
Shares or the fair market value of the First Refusal Shares, as applicable,  for
purposes of Section 3.5(a), shall equal the middle determination.

                    (iv) Any appraiser  retained pursuant to this Section 3.5(d)
shall  be  nationally  recognized  as being  qualified  and  experienced  in the
appraisal of assets  comparable to the First Refusal  Shares and, if applicable,
any other assets proposed to be sold pursuant to the Third Party Offer and shall
not be an Affiliate of any party to this Agreement. All fees and expenses of any
appraiser  retained pursuant to this Section 3.5(d) shall be paid by the Selling
Stockholder.

                    (v) In  determining  the  fair  market  value  of the  First
Refusal Shares, if applicable,  each appraiser retained pursuant to this Section
3.5(d) shall:  (A) assume that the fair market value of the applicable  asset is
the price at which the asset would  change hands  between a willing  buyer and a
willing  seller,  neither  being  under any  compulsion  to buy or sell and each
having  reasonable  knowledge  of  all  relevant  facts;  (B)  assume  that  the
applicable  asset would be sold for cash; and (C) use valuation  techniques then
prevailing in the relevant industry.

          3.6 Pre-IPO Right of First Offer.

               (a) If  the  Company's  initial  Public  Offering  has  not  been
consummated by September 30, 1996, then each Consenting  Stockholder  shall have
the right,  at any time  thereafter  but prior to the  consummation  of a Public
Offering  (the  "Pre-IPO   Period"),   to  deliver  to  the  other   Designating


                                     - 22 -

Stockholders a notice (a "Pre-IPO  Notice of Sale" and,  together with the First
Offer  Notice of Sale and the First  Refusal  Notice of Sale,  the  "Notices  of
Sale") of such Consenting  Stockholder's  intention to sell, assign or otherwise
dispose  of the  shares of Class A Common  Stock  into  which all or part of its
shares of Class B Common Stock may be converted (the "Pre-IPO  Offered  Shares,"
and,  together  with the First Offer Shares and the First  Refusal  Shares,  the
"Offered Shares"). Such Consenting Stockholder (the "Pre-IPO Offeror") shall not
sell or assign,  or offer to sell or assign,  or otherwise dispose of any of its
shares of Class B Common  Stock  (other than a  disposition  pursuant to Section
3.3, 3.4 or 3.5),  or convert  such shares into shares of Class A Common  Stock,
unless and until it has delivered a Pre-IPO  Notice of Sale with respect to such
shares to the other  Designating  Stockholders  pursuant to this Section 3.6 and
otherwise  complied with the provisions of this Section 3.6. Such Pre-IPO Notice
of Sale shall contain the Pre-IPO  Offeror's  offer to sell the Pre-IPO  Offered
Shares to the other  Designating  Stockholders,  and shall specify the terms and
conditions of such sale,  including the number of Pre-IPO Offered Shares and the
price per Pre-IPO Offered Share (which price shall,  unless  otherwise agreed by
the Pre-IPO  Offeror and the Designating  Stockholders  accepting such offer, be
payable in cash).

                    (i) If any of the other Designating  Stockholders desires to
accept all or any  portion  of the offer set forth in a Pre-IPO  Notice of Sale,
such Designating  Stockholder (a "Pre-IPO  Electing  Stockholder"  and, together
with the  First  Offer  Electing  Stockholders  and the First  Refusal  Electing
Stockholders,  the "Electing  Stockholders")  shall, within ten Business Days of
receipt  of such  Pre-IPO  Notice of Sale,  notify  the  Pre-IPO  Offeror of its
intention  to acquire  Pre-IPO  Offered  Shares and the number of such shares it
desires to acquire,  and deliver a copy of such notice to each other Designating
Stockholder.

                    (ii) If the Pre-IPO Electing Stockholders desire to acquire,
in the aggregate,  all of the Pre-IPO Offered Shares,  then the Pre-IPO Electing
Stockholders  shall have the right to acquire  all the Pre-IPO  Offered  Shares,
allocated among them as follows (or in such other manner as the Pre-IPO Electing
Stockholders may agree):

                    (A) the Pre-IPO  Offered Shares shall be allocated among the
Pre-IPO Electing Stockholders pro rata (based on the number of shares of Class B
Common Stock owned by each of them) until all of the Pre-IPO Offered Shares have
been allocated or any Pre-IPO Electing Stockholder has been allocated the number
of Pre-IPO Offered Shares that it desires to acquire, as specified in its notice
to the  Pre-IPO  Offeror,  as it may  have  been  amended  pursuant  to  Section
3.6(a)(iii);

                    (B) if all Pre-IPO Offered Shares are not allocated pursuant
to paragraph (A) or any prior  application  of this  paragraph  (B), any Pre-IPO
Offered  Shares that were not  allocated  pursuant to paragraph (A) or any prior
application of this paragraph (B) shall be allocated among the Pre-IPO  Electing
Stockholders  (other  than  any  Pre-IPO  Electing  Stockholder  that  has  been
allocated the number of Pre-IPO  Offered  Shares that it desires to acquire,  as
specified  in its notice to the  Pre-IPO  Offeror,  as it may have been  amended
pursuant  to  Section  3.6(a)(iii))  pro rata  (based on the number of shares of
Class B Common Stock owned by each of them); and

                    (C) if all Pre-IPO Offered Shares are not allocated pursuant
to paragraph (A) and any prior application of paragraph (B), any Pre-IPO Offered
Shares  that  were  not  allocated  pursuant  to  paragraph  (A) and  any  prior
application of paragraph (B) shall be allocated by continuing to apply paragraph
(B) as required.

                    (iii)  If  the  Pre-IPO  Electing   Stockholders  desire  to
acquire, in the aggregate, less than all of the Pre-IPO Offered Shares, then the
Pre-IPO Offeror shall so notify the Pre- IPO Electing Stockholders and:

                    (A) each Pre-IPO Electing  Stockholder shall have the right,
by written  notice  sent to the Pre-IPO  Offeror  (with a copy of such notice to
each other  Designating  Stockholder)  within five days after its receipt of the
notice from the Pre-IPO  Offeror  pursuant to this Section  3.6(a)(iii) to amend
its notice to increase the number of Pre-IPO  Offered  Shares that it desires to
purchase;

                    (B) if, after giving  effect to any amendment to any Pre-IPO
Electing Stockholder's notice pursuant to this Section 3.6(a)(iii),  the Pre-IPO
Electing  Stockholders desire to acquire,  in the aggregate,  all of the Pre-IPO
Offered Shares,  then the Pre-IPO Electing  Stockholders shall have the right to
acquire all the Pre-IPO Offered Shares,  allocated among them in accordance with
Section 3.6(a)(ii); and

                    (C) if, after giving  effect to any amendment to any Pre-IPO
Electing Stockholder's notice pursuant to this Section 3.6(a)(iii),  the Pre-IPO
Electing Stockholders desire to acquire, in the aggregate,  less than all of the
Pre-IPO Offered Shares,  then the Pre-IPO Offeror's offer of the Pre-IPO Offered
Shares  shall be  deemed  rejected  as of the last  day for a  Pre-IPO  Electing
Stockholder to amend its notice pursuant to this
Section 3.6(a)(iii).

                    (iv)   Notwithstanding  the  foregoing  provisions  of  this
Section  3.6(a),  the allocation of the Pre-IPO Offered Shares among the Pre-IPO
Electing Stockholders shall be subject to Section 3.7(a).

               (b) If (i) the Pre-IPO  Offeror's  offer of the  Pre-IPO  Offered
Shares is rejected as provided in Section  3.6(a),  or (ii) the  purchase of the
Pre-IPO Offered Shares is not consummated within the period set forth in Section
3.7(b) for any reason  other than a breach by the Pre-IPO  Offeror of any of its
covenants, representations or warranties that are a condition to consummation of
such purchase, then the Pre-IPO Offeror shall have the right, at any time during
the sixty-day period  beginning on the date that the Pre-IPO  Offeror's offer of
the Pre-IPO  Offered Shares is deemed rejected or the day following the last day
of the period set forth in Section 3.7(b), as applicable, to convert all Class B
Common Stock included in the Pre-IPO  Offered Shares to Class A Common Stock and
to enter into a binding  agreement  to sell all of such shares of Class A Common
Stock  to a third  party  on  terms  and  conditions  no less  favorable  in the
aggregate to the Pre-IPO  Offeror than those set forth in the Pre- IPO Notice of
Sale and thereafter  (within the period  specified below in this Section 3.6(b))
to sell all of such shares of Class A Common Stock to such third party  pursuant
to such  agreement.  In no event  shall the  Pre-IPO  Offeror  have the right to
transfer any shares of Class B Common Stock  pursuant to this Section 3.6 except
to the Pre-IPO Electing Stockholders.  The Pre-IPO Offeror shall, as promptly as
practicable  and  prior  to the  closing  of such  sale,  provide  to the  other
Designating  Stockholders  a copy of the  agreement  for the sale of the Pre-IPO
Offered  Shares so as to permit the  Designating  Stockholders  to  confirm  for
themselves  that the terms and conditions of such sale are not less favorable in
the aggregate to the Pre-IPO  Offeror than those set forth in the Pre-IPO Notice
of Sale.  If the Pre-IPO  Offeror does not enter into such an  agreement  during
such sixty-day  period,  or does not close the sale thereunder within sixty days
after the execution of such an agreement  (subject to extension for a maximum of
180 additional days to the extent required to obtain all required  governmental,
regulatory  and other third party  consents and  approvals),  the  procedure set
forth above with  respect to the Pre-IPO  Notice of Sale shall be repeated  with
respect to any  subsequent  proposed  sale,  assignment or other  disposition of
shares of Common Stock by such Pre-IPO Offeror during the Pre-IPO Period.

               (c) If, during the sixty-day  period after the  expiration of the
relevant period set forth in Section 3.6(b), the Pre-IPO Offeror receives a bona
fide offer in writing from any third party to purchase only a part of the shares
of Class A Common Stock into which the Pre-IPO  Offered  Shares may be converted
or to purchase  all of the shares of Class A Common Stock into which the Pre-IPO
Offered  Shares may be converted on terms and  conditions  less favorable in the
aggregate to the Pre- IPO Offeror than those set forth in the Pre-IPO  Notice of

Sale, and the Pre-IPO Offeror desires to accept such offer,  the Pre-IPO Offeror
shall  give  notice  of  the  terms  of  such  offer  to the  other  Designating
Stockholders  and the  procedure  set forth  above with  respect to the  initial
Pre-IPO Notice of Sale shall be repeated with respect to such offer.

          3.7 Terms and  Conditions  of Sales  Pursuant to Sections 3.4, 3.5 and
3.6.

               (a) The  acquisition  by any  Electing  Stockholder  (the "Excess
Shares  Stockholder"),  as a result of its election to exercise  rights  granted
pursuant to Section  3.4(a),  3.5(a) or 3.6(a),  of any shares of Class B Common
Stock (the "Excess  Shares")  which,  when added to the shares of Class B Common
Stock held by such  Electing  Stockholder  immediately  prior to such  election,
would cause its  percentage  of the total  outstanding  Class B Common  Stock to
exceed 49% shall be subject to the  application of this Section  3.7(a).  If, in
connection with any offer made pursuant to Section 3.4(a), 3.5(a) or 3.6(a), any
Electing Stockholder would, but for the application of this Section 3.7(a), have
the right to acquire Excess Shares, then (i) the Excess Shares Stockholder shall
have the right to acquire that number of Excess Shares which,  when added to the
shares of Class B Common Stock held by the Excess Shares Stockholder immediately
prior to such  election,  would cause its  percentage  of the total  outstanding
Class B Common Stock to equal 49% and (ii) each Electing  Stockholder other than
the Excess  Shares  Stockholder  shall  have the right to  acquire  its pro rata
portion  (based on the number of shares of Class B Common  Stock owned by it and
the  number  of  shares  of Class B  Common  Stock  owned  by all such  Electing
Stockholders other than the Excess Shares Stockholder), or such other portion as
such other Electing  Stockholders may agree among  themselves,  of the remaining
Excess  Shares;  provided,   however,  that  if  there  are  two  Excess  Shares
Stockholders in connection with any election to exercise rights granted pursuant
to Section 3.4(a),  3.5(a) or 3.6(a),  then each Excess Shares Stockholder shall
have the right to acquire that number of Excess Shares which,  when added to the
shares  of  Class  B  Common  Stock  held  by  such  Excess  Shares  Stockholder
immediately  prior to such  election,  would cause its  percentage  of the total
outstanding  Class B Common Stock to equal 49% and any  remaining  Excess Shares
shall be split  equally  between such Excess  Shares  Stockholders.  Each Excess
Shares  Stockholder  shall have the right to acquire  any  portion of the Excess
Shares which the other Electing Stockholders have not agreed to acquire.

               (b) Any  purchase  and sale of Common  Stock  pursuant to Section
3.4, 3.5 or 3.6 shall be subject to the following terms and conditions:

                    (i) the selling  Consenting  Stockholder shall represent and
warrant that the buying Consenting Stockholders will receive good and valid

                                     - 26 -

title to the Offered Shares,  free and clear of all security  interests,  liens,
claims, pledges, options, rights of first refusal, limitations on voting rights,
charges and other  encumbrances of any nature  whatsoever except as set forth in
this  Agreement and except for  governmental,  regulatory  and other third party
consents  and  approvals  required  for  transfers  of shares  of  Common  Stock
generally;

                    (ii)  closing of the  purchase  and sale shall be subject to
the satisfaction of following conditions:

                    (A)   all    applicable    waiting    periods    under   the
Hart-Scott-Rodino  Antitrust Improvements Act of 1976, as amended, and the rules
and regulations promulgated thereunder, shall have expired or been terminated;

                    (B)  all  governmental   approvals  and  other  third  party
consents  expressly  required with respect to the transactions to be consummated
at such closing  shall have been  obtained,  to the extent the failure to obtain
such approvals or consents would prevent the Converting Stockholder, the Selling
Stockholder or the Pre-IPO  Offeror,  as the case may be, from performing any of
its material obligations under the transaction  documents or would result in any
materially  adverse  change in, or materially  adverse  effect on, the business,
assets,  results of operations,  financial condition or prospects of the Company
and the Persons controlled by the Company taken as a whole;

                    (C) there shall be no preliminary or permanent injunction or
other order by any court of competent  jurisdiction  restricting,  preventing or
prohibiting  the  consummation  of the  transactions  to be  consummated at such
closing;

                    (D)  the  representation  and  warranty  of  the  Converting
Stockholder,  the Selling  Stockholder or the Pre- IPO Offeror,  as the case may
be, contemplated by clause (i) of this sentence shall be true and correct at the
closing of such sale with the same force and effect as if then made; and

                    (iii) The closing of any  purchase  and sale of Common Stock
pursuant to Section 3.4, 3.5 or 3.6 shall take place as promptly as practicable,
but in any event within sixty days after the acceptance of the applicable offer,
subject to extension for a maximum of one hundred eighty  additional days to the
extent required to obtain all required governmental,  regulatory and other third
party consents and approvals.

               (c) In  furtherance  of the rights set forth in Sections 3.4, 3.5
and 3.6, the Company agrees that, on reasonable notice following the delivery of
a Notice of Sale, at reasonable times and without  interfering with the business


                                     - 27 -


<PAGE>


or operations of the Company,  it will assist the  Converting  Stockholder,  the
Selling Stockholder or the Pre-IPO Offeror, as the case may be, in obtaining all
necessary consents to any disposition of the Offered Shares.

          3.8 Transferee Consenting Stockholders.

               (a)  A   Consenting   Stockholder   shall   remain  a  Consenting
Stockholder  for so long as it owns any Class B Common Stock  regardless  of the
percentage of Class B Common Stock it may own from time to time.  Any transferee
of a  Consenting  Stockholder  required  to  become  a party  to this  Agreement
pursuant  to Section  3.3 or Section  3.5(c) of this  Agreement  shall  become a
Consenting  Stockholder  by delivering to the Company (which shall promptly send
notice thereof to the Consenting  Stockholders) a counterpart  signature page to
this  Agreement and, if it is then in effect,  the  Supplemental  Agreement.  No
further action by the Company or the Consenting  Stockholders  shall be required
for such  person to become a party to this  Agreement.  Following  any  Indirect
Transfer permitted by this Agreement, the Consenting Stockholder with respect to
which such Indirect  Transfer has occurred shall confirm to the other Consenting
Stockholders  in  writing  the  continuing  validity  and  effectiveness  of its
obligations under this Agreement and, if it is then in effect,  the Supplemental
Agreement.

               (b) If TCI Communications, Inc. elects in accordance with Section
3.4(a) of the  Reorganization  Agreement to cause shares of Class B Common Stock
allocable to the Viacom Interests (as defined in the  Reorganization  Agreement)
to be  issued  to a  Subsidiary  of TCI  Communications,  Inc.  other  than  TCI
Teleport, Inc., such Subsidiary shall become a party to this Agreement and shall
become a  Consenting  Stockholder  by  delivering  to the Company  (which  shall
promptly  send notice  thereof to the  Consenting  Stockholders)  a  counterpart
signature page to this Agreement and, if it is then in effect,  the Supplemental
Agreement.

          3.9 Continental  Waiver.  Continental agrees to consent to any request
for a waiver from the transfer restrictions contained in this Section 3 which is
requested by  Consenting  Stockholders  that hold at least fifty  percent of the
outstanding shares of Class B Common Stock held by Consenting Stockholders other
than Continental,  so long as Continental is offered the same opportunity either
(as determined by the Consenting Stockholders that made such request):

               (a) to  participate  in the  transfer  for which  such  waiver is
requested  on a pro rata basis  (based on the ratio that the number of shares of
Class B Common Stock subject to such request bears to the total number of shares
of Class B Common Stock held by all Consenting Stockholders other than

                                     - 28 -


<PAGE>



Continental),  and on the same terms and conditions,  as the proposed transferor
or transferors with respect to which such request is made; or

               (b) to  receive  cash in  exchange  for  shares of Class B Common
Stock in an amount  equal to the fair  market  value of the  consideration  that
Continental  would have been  entitled  to receive  upon the  transfer of a like
number of shares of Class B Common  Stock had  Continental  participated  in the
transfer  for which such waiver is requested on a pro rata basis as described in
Section  3.9(a);  for purposes of this Section  3.9(b),  if the transferors in a
transaction with respect to which such a request is made contribute their shares
of Class B Common  Stock to an entity and receive  capital  contribution  credit
therefor  in an amount  determined  by arms'  length  negotiations  between  the
transferors and one or more Persons that are not Affiliates of the  transferors,
then the fair market value of the consideration received by the transferors with
respect  to such  contribution  shall  be equal to the  amount  of such  capital
contribution  credit  and  the  fair  market  value  of the  consideration  that
Continental  would have been  entitled  to receive  had it  participated  in the
transaction shall be proportionate to that received by the transferors (based on
the relative numbers of shares of Class B Common Stock involved).

          3.10 Cooperation.  Each Consenting  Stockholder shall use commercially
reasonable efforts to cooperate with any transferring  Consenting Stockholder in
connection  with its efforts to  transfer  any  interest in its Common  Stock in
accordance  with the  provisions of this Section 3, including  making  qualified
personnel available for attending hearings and meetings respecting any consents,
approvals and  authorizations  required for such transfer and, at the request of
the transferring Consenting Stockholder, making all filings with, and giving all
notices to, third parties and governmental  authorities that may be necessary or
reasonably  required to be made or given by such of the Consenting  Stockholders
in order to effect the contemplated  transfers.  Subject to the other provisions
of this  Section,  no  Consenting  Stockholder  shall  take any action to delay,
impair  or  impede  the  receipt  of  any   required   consents,   approvals  or
authorizations.  "Commercially reasonable efforts" as used in this Section shall
not require any party to undertake  extraordinary  or  unreasonable  measures to
obtain any consents, approvals or other authorizations, including requiring such
party to make any material  expenditures  (other than normal  filing fees or the
like) or to accept any material changes in the terms of the contract, license or

SECTION 4         REGISTRATION RIGHTS

          4.1 Demand Registrations.

               (a) Requests for  Registration.  At any time after the date which
is six months after the closing of the Company's  initial Public  Offering,  any
stockholder  of the Company  which is a party to this  Agreement  (an  "Eligible
Holder")  may  request  that the  Company  effect  the  registration  under  the
Securities  Act of all or part of its shares of Class A Common Stock  (including
shares of Class A Common Stock  issuable  upon  conversion  of shares of Class B
Common  Stock held by it) for sale in the manner  specified in such  request.  A
stockholder  that previously  owned shares of Class B Common Stock but ceased to
be a Consenting  Stockholder upon the conversion of its shares of Class B Common
Stock to shares of Class A Common  Stock  shall  continue  to be a party to this
Agreement  so long as it owns any shares of Class A Common  Stock and  therefore
shall be an Eligible  Holder.  Such request shall be made by furnishing  written
notice thereof (a "Demand  Notice") to the Company,  setting forth the number of
shares of Class A Common Stock  requested  to be  registered  and such  Eligible
Holder's preferred method of distribution.  Within ten days after receipt of any
Demand  Notice,  the Company shall give written  notice of such Demand Notice to
all other  Eligible  Holders.  Following  receipt  of a Demand  Notice  from the
Company (the "Company  Notice"),  each such other  Eligible  Holder may give the
Company a written request to register any or all of such Eligible Holder's Class
A  Common  Stock  (including  shares  of  Class A  Common  Stock  issuable  upon
conversion  of shares of Class B Common  Stock  held by it) in the  registration
described in the Company  Notice,  provided  that such written  request is given
within  fifteen  days after the date on which the Company  Notice is given (with
such  request  stating (i) the number of shares of Class A Common Stock to be so
included,  (ii) such other Eligible Holder's preferred method of distribution of
such shares and (iii) any other  information that the Company Notice  reasonably
requests  be  included  in  such  notice  from  such   Eligible   Holder).   All
registrations  requested  pursuant to this Section 4.1(a) are referred to herein
as "Demand  Registrations." The Company shall not be required to effect a Demand
Registration  unless  the  aggregate  number of  shares of Class A Common  Stock
demanded to be so  registered is at least two percent of the number of shares of
Common  Stock  then  outstanding  (the  "Minimum  Condition").  If  the  Minimum
Condition is met, then, subject to Sections 4.1(b), 4.1(c) and 4.1(f) below, the
Company  shall,  as  soon  as  practicable,  file  with  the  SEC  and  use  all
commercially  reasonable  efforts to cause to become  effective  as  promptly as
practicable,  a Registration  Statement  which shall cover the shares of Class A
Common Stock requested to be registered pursuant to such Demand Notices.

<PAGE>



               (b) Number of Demand  Registrations.  Once a Demand  Registration
has been effected, the Company shall not be obligated to register Class A Common
Stock pursuant to another Demand  Registration prior to the expiration of twelve
months from the date on which the  previous  Demand  Registration  was  declared
effective;  provided,  however,  that a registration  will not count as a Demand
Registration  unless it has become  effective,  and such  effectiveness has been
maintained  under  the  Securities  Act (and  not  subject  to any  stop  order,
injunction or other order or requirement of the SEC or other governmental agency
or court for any  reason)  for the  period  specified  in Section  4.3(b).  Each
Eligible  Holder  may,  before any  Registration  Statement  becomes  effective,
withdraw its shares of Class A Common Stock from inclusion  therein if the terms
of the proposed  distribution are not  satisfactory to such Eligible Holder.  If
after giving effect to such  withdrawal or  withdrawals  of shares from a Demand
Registration  the  Minimum  Condition  would no longer be  satisfied,  then such
Registration  Statement shall be withdrawn.  A registration that is withdrawn at
the request of the Eligible Holders that demanded such Demand  Registration will
not count as a Demand Registration.

               (c) Restrictions on  Registrations.  The Company may postpone for
up to three  months  after  its  receipt  of a Demand  Notice  the  filing  of a
registration  statement  for a Demand  Registration  if the  Company  reasonably
believes that such Demand  Registration  would have a material adverse effect on
any proposal or plan by the Company or any of its  Subsidiaries to engage in any
financing, acquisition of assets (other than in the ordinary course of business)
or any merger, consolidation,  tender offer or other significant transaction and
notifies the Eligible Holders in writing of such postponement; provided that the
Company  shall have the right to so postpone such filing or  effectiveness  only
one time during any period of twelve consecutive months; and provided,  further,
that the three-month  limitation  contained above in this Section 4.1(c) and the
limitation contained in the first proviso to this Section 4.1(c) shall not apply
if the shares  proposed to be registered by the Eligible  Holder  furnishing the
applicable Demand Notice could then be sold without restrictions  (including any
volume limitation) under the Securities Act.

               (d) Underwriting.

                    (i) Subject to Section 4.1(e), the distribution of the Class
A Common Stock covered by the Demand  Registration shall be effected by means of
a firm  commitment  underwriting,  and  the  right  of any  Eligible  Holder  to
registration  pursuant to this Section 4 shall be conditioned upon such Eligible
Holders'  participation in such  underwriting and the inclusion of such Eligible
Holder's Class A Common Stock in the  underwriting  (unless  otherwise  mutually


                                     - 31 -


<PAGE>


agreed by a majority in interest  of the other  Eligible  Holders) to the extent
provided herein.  The Company  (together with all Eligible Holders  proposing to
distribute  their Class A Common Stock  through such  underwriting)  shall enter
into an underwriting  agreement in customary form with a managing underwriter of
nationally  recognized  standing  selected for such  underwriting by the Company
with the approval of the Eligible Holder that has included the largest number of
shares  in  the  Demand   Registration,   such   approval  not  to  be  withheld
unreasonably.  No Eligible  Holder may  participate  in any Demand  Registration
unless such  Eligible  Holder (A) agrees to sell its Class A Common Stock on the
basis provided in such underwriting agreement and (B) completes and executes all
questionnaires,  powers of attorney,  indemnities and other  documents  required
under the terms of such underwriting agreement.

                    (ii)  Notwithstanding any other provision of this Section 4,
if the  managing  underwriter  advises the Company and the  Eligible  Holders in
writing that marketing  factors  require a limitation of the number of shares to
be underwritten,  then the managing  underwriter may exclude shares requested to
be included in such Demand Registration.  The number of shares of Class A Common
Stock that may be included in the Demand  Registration and underwriting shall be
allocated  among  the  Eligible  Holders  who  have  requested  registration  in
accordance  with the  provisions  of  Section  4.1(f).  No Class A Common  Stock
excluded from the underwriting by reason of the managing underwriter's marketing
limitation shall be included in such Demand Registration.

                    (iii)  If any  Eligible  Holder  participating  in a  Demand
Registration disapproves of the terms of the underwriting, such person may elect
to withdraw therefrom by written notice to the Company, the managing underwriter
and the other Eligible Holders. If by such withdrawal a greater number of shares
of Class A Common Stock held by other  Eligible  Holders may be included in such
Demand Registration (up to the maximum of any limitation imposed by the managing
underwriter), then the Company shall offer to all Eligible Holders participating
in the Demand  Registration  the right to include  additional  shares of Class A
Common  Stock,  which  additional  shares shall be allocated  among the Eligible
Holders who have  requested  registration  in accordance  with the provisions of
Section 4.1(f).

               (e) Shelf  Registration.  If at the time of a Demand Notice,  the
Company  is  eligible  to file a  registration  statement  on  Form  S-3 (or any
equivalent  successor form),  then Eligible Holders who hold at least 51% of the
shares of Class A Common Stock which are to be included in a Demand Registration
may  request  that the  Demand  Registration  be  effected  pursuant  to a shelf
registration under Rule 415 of the Securities Act; provided,  however,  that (i)


                                     - 32 -


<PAGE>


if  the  Company  shall  reasonably   determine,   after  consultation  with  an
independent investment banking firm of nationally recognized standing, that such
method of distribution  would adversely affect the public market for the Class A
Common  Stock,  then the  Company  shall not be  obligated  to effect the Demand
Registration  pursuant to such method of distribution,  and (ii) during the term
of any such shelf  registration,  the Company may require from time to time that
the  Eligible  Holders  refrain  from  selling  pursuant  to  such  registration
statement  under  the  circumstances,  in the  manner  and for the  time  period
described in Section 4.1(c).

               (f)   Allocation   among  Eligible   Holders.   If  the  managing
underwriter  imposes a limit on the number of shares of Class A Common  Stock to
be included in the Demand Registration, then each Eligible Holder shall have the
right to include in such Demand  Registration up to its pro rata share (based on
the ratio that the number of shares of Class A Common Stock  proposed to be sold
by it bears to the total number of shares of Class A Common Stock proposed to be
sold by all  Eligible  Holders  who have  elected to  participate  in the Demand
Registration)  of the  maximum  number  of  shares  permitted  by  the  managing
underwriter to be included in the Demand  Registration  (the "Maximum  Amount");
provided,  however,  that, if and to the extent that Continental is then subject
to a  regulatory  requirement  as a result of the U S West  Transaction  that it
reduce or eliminate its  investment in the Company,  during the period ending on
the date which is thirty months after the date of the Company's  initial  Public
Offering,  Continental  shall  have the right (to the  extent it has  elected to
participate in such Demand  Registration) to include in the Demand  Registration
up to  one-half  of the Maximum  Amount,  and the balance of the Maximum  Amount
shall be allocated among the other  participating  Eligible  Holders pro rata as
provided in the main clause of this sentence;  and provided,  further,  that, if
and to the extent that  Continental is then subject to a regulatory  requirement
as a  result  of the U S West  Transaction  that  it  reduce  or  eliminate  its
investment in the Company, during the twelve-month period commencing on the date
which is thirty months after the date of the Company's  initial Public Offering,
Continental shall have the right (to the extent it has elected to participate in
such  Demand  Registration)  to include in the  Demand  Registration  all of the
Maximum Amount, and any portion of the Maximum Amount that exceeds the number of
shares that Continental  elects to include in the Demand  Registration  shall be
allocated among the other participating Eligible Holders pro rata as provided in
the main clause of this sentence.

               (g) Inclusion of Shares by Company.  If the managing  underwriter
has not limited the number of shares of Class A Common Stock to be  underwritten
or if the number of shares  which the  Eligible  Holders  have  requested  to be
registered  is less  than the  Maximum  Amount,  then the  Company  may  include
securities for its own account or for the account of others in such Demand 

                                     - 33 -


<PAGE>



Registration  if the managing  underwriter so agrees and if the number of shares
of Class A Common Stock held by Eligible Holders which would otherwise have been
included  in such  Demand  Registration  and  underwriting  will not  thereby be
limited.  The  inclusion  of such  shares  shall  be on the  same  terms  as the
registration  of shares  held by the  Eligible  Holders.  In the event  that the
managing  underwriter  excludes  some of the  securities to be  registered,  the
securities to be sold for the account of the Company and any other holders shall
be excluded in their  entirety  prior to the  exclusion of any shares of Class A
Common Stock of the Eligible Holders.

          4.2 Lockup  Agreements.  Each Eligible Holder agrees not to effect any
public sale or other  distribution of Class A Common Stock during the seven days
prior to the effective  date of any Public  Offering or Demand  Registration  or
during the ninety-day  period beginning on such effective date (except in either
case as part of such Demand  Registration and except that Continental  shall not
be prohibited from effecting any such public sale or other  distribution  during
such  period  after the  effective  date of a Public  Offering  not  being  made
pursuant to a Demand  Registration  if it is required to sell within such period
by any regulatory  requirement resulting from the U S West Transaction),  unless
the managing underwriter  otherwise agrees. The Company agrees not to effect any
public sale or other  distribution of Class A Common Stock during the seven days
prior to the effective date of any Demand  Registration or during the ninety-day
period  beginning on such  effective date (except in either case as part of such
Demand  Registration or pursuant to  registrations  on Form S-8 or any successor
form), unless the managing underwriter otherwise agrees.

          4.3 Registration Procedures.  Whenever the Company is obligated by the
provisions of this Agreement to effect a  registration  of any shares of Class A
Common  Stock  under the  Securities  Act,  the Company  shall use  commercially
reasonable  efforts to effect  such  registration  and the sale of the shares of
Class A Common Stock covered  thereby in accordance  with the intended method of
disposition  thereof,  and pursuant thereto the Company will as expeditiously as
possible:

               (a) prepare and file with the SEC a  registration  statement with
respect to such shares and use all commercially reasonable efforts to cause such
registration  statement to become and remain effective for such period as may be
reasonably necessary to effect the sale of such securities, not to exceed ninety
days;

               (b) prepare and file with the SEC such amendments and supplements
to such registration  statement and the prospectus used in connection  therewith
as may be  necessary to keep such  registration  statement  effective  until the


                                     - 34 -


<PAGE>


sooner to occur of the sale of all such shares or the  ninetieth  day  following
the effective date of such registration statement and comply with the provisions
of the Securities Act with respect to the disposition of all securities  covered
by such  registration  statement  during  such  period  in  accordance  with the
intended  methods  of  disposition  by the  sellers  thereof  set  forth in such
registration statement;

               (c) furnish to each Eligible Holder  participating in such Demand
Registration  and the  underwriters  such number of copies of such  registration
statement,  each amendment and supplement  thereto,  the prospectus  included in
such  registration  statement  (including each preliminary  prospectus) and such
other documents as such seller or underwriters  may reasonably  request in order
to facilitate the sale of the shares being sold;

               (d) use all reasonable  efforts to register or qualify the shares
being sold under such other securities or blue sky laws of such jurisdictions as
any seller  reasonably  requests  and do any and all other acts and things which
may be reasonably necessary or advisable to enable such seller to consummate the
disposition in such jurisdictions of the shares owned by such seller;  provided,
however,  that the Company  will not be required to (i) qualify  generally to do
business in any jurisdiction where it would not otherwise be required to qualify
but for this subparagraph, (ii) conform its capitalization or the composition of
its assets to the  securities  or blue sky laws of such  jurisdictions  or (iii)
consent to general service of process in any such jurisdiction;

               (e)  cause  all  such  shares  to be  listed  or  authorized  for
quotation on each  securities  exchange or automated  quotation  system on which
similar securities issued by the Company are then listed or quoted;

               (f) notify each seller of such  shares,  promptly  after it shall
receive notice thereof, of the time when such registration  statement has become
effective or a supplement to any prospectus  forming a part of such registration
statement has been filed;

               (g) notify  each  seller of such shares of any request by the SEC
for the amending or supplementing of such  registration  statement or prospectus
or for additional information;

               (h) prepare and file with the SEC,  promptly  upon the request of
any seller of such shares,  any amendments or  supplements to such  registration
statement or prospectus which, in the opinion of counsel selected by the holders
of a majority of the shares being  registered,  is required under the Securities
Act in connection with the distribution of shares by such seller;

                                     - 35 -


<PAGE>




               (i)  prepare and  promptly  file with the SEC each  amendment  or
supplement to such  registration  statement or prospectus as may be necessary to
correct any  statements or omissions if, at the time when a prospectus  relating
to such  securities is required to be delivered  under the  Securities  Act, any
event  shall have  occurred  as the result of which any such  prospectus  or any
other  prospectus  as then in effect  would  include  an untrue  statement  of a
material  fact or  omit  to  state  any  material  fact  necessary  to make  the
statements  therein,  in the light of the circumstances in which they were made,
not misleading; and

               (j) advise each seller of such  shares,  promptly  after it shall
receive notice or obtain knowledge thereof, of the issuance of any stop order by
the SEC  suspending  the  effectiveness  of such  registration  statement or the
initiation or  threatening  of any  proceeding for such purpose and promptly use
commercially  reasonable efforts to prevent the issuance of any stop order or to
obtain its withdrawal if such stop order should be issued.

          4.4  Expenses.  Each  Eligible  Holder that  participates  in a Demand
Registration  (including  a  Demand  Registration  that is  withdrawn  prior  to
becoming effective) shall pay all underwriting discounts and commissions and any
transfer taxes  attributable to the sale of such Eligible  Holder's shares,  the
fees and expenses of counsel for such Eligible Holder,  any other  out-of-pocket
expenses of such Eligible Holder  incurred in connection with its  participation
in such Demand  Registration and its pro rata share (based on the ratio that the
number  of  shares  of Class A Common  Stock to be sold by it bears to the total
number of shares of Class A Common Stock to be sold by all Eligible  Holders who
have elected to participate  in the Demand  Registration)  of any  out-of-pocket
expenses incurred by the Company in connection with such Demand Registration.

          4.5 Preparation of Registration Statement. Each Eligible Holder agrees
to furnish to the Company  such written  information  concerning  such  Eligible
Holder as may  reasonably  be  requested  by the Company  which is  necessary in
connection with any Demand Registration.

          4.6 Indemnification.

               (a) In the event that the Company  effects a registration  of any
shares owned by an Eligible  Holder,  such Eligible  Holder shall  indemnify and
hold the Company,  and each of its  directors  and officers and each person,  if
any, who controls the Company within the meaning of the federal  securities laws
(the "Company Indemnified Parties") harmless against all losses, liabilities and


                                     - 36 -


<PAGE>


expenses  of any nature  whatsoever  which the Company  Indemnified  Parties may
incur as a result of or arising  out of or based upon any  untrue  statement  or
alleged  untrue  statement  of a material  fact  contained  in the  registration
statement  filed by the Company  (including  any  prospectus  contained  in such
registration  statement and any post-effective  amendment or supplement thereto)
or as a result  of or  arising  out of or based  upon the  omission  or  alleged
omission  to  state  therein  a  material  fact  necessary  in order to make the
statements  therein,  in the light of the  circumstances  under  which they were
made,  not  misleading,  which untrue  statement  or omission or alleged  untrue
statement or omission was made in such  registration  statement  (including  any
prospectus  contained  in such  registration  statement  and any  post-effective
amendment  or  supplement  thereto)  in  reliance  upon and in  conformity  with
information  furnished  in  writing  by or behalf of such  Eligible  Holder  for
inclusion  therein;  provided,  however,  that such Eligible Holder shall not be
liable to the extent that the losses,  liabilities  or expenses  arise out of or
are based  upon (i) the use by the  Company or  another  Eligible  Holder of any
prospectus  after such time as the  obligation  of the  Company to keep the same
effective  and  current  has  expired or (ii) the use by the  Company or another
Eligible  Holder of any prospectus  after such time as such Eligible  Holder has
advised the Company that the filing of a post-effective  amendment or supplement
thereto is required with respect to any information contained in such prospectus
concerning  such  Eligible  Holder,  except  such  prospectus  as so  amended or
supplemented.

               (b) In the event that the Company  effects a registration  of any
shares owned by an Eligible  Holder,  the Company shall  indemnify and hold such
Eligible Holder, and each of its directors and officers and each person, if any,
who controls the Eligible  Holder  within the meaning of the federal  securities
laws (the  "Stockholder  Indemnified  Parties")  harmless  against  all  losses,
liabilities  and  expenses  of any  nature  whatsoever  which  such  Stockholder
Indemnified Parties may incur as a result of or arising out of or based upon any
untrue statement or alleged untrue statement of a material fact contained in the
registration  statement filed by the Company (including any prospectus contained
in such registration  statement and any  post-effective  amendment or supplement
thereto)  or as a result of or  arising  out of or based  upon the  omission  or
alleged  omission to state therein 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,  provided,  however,
that the  Company  will not be liable in any such  case to the  extent  that the
losses,  liabilities  or expenses  arise out of or are based upon (i) any untrue
statement  or  omission or alleged  untrue  statement  or omission  made in such
registration  statement (including any prospectus contained in such registration
statement and any post-effective amendment or supplement thereto)  in reliance


                                     - 37 -


<PAGE>


upon and in conformity with information  furnished in writing by or on behalf of
such  Eligible  Holder  to the  Company  for  inclusion  therein  in  connection
therewith,  (ii) the use of any prospectus  after such time as the obligation of
the Company to keep the same effective and current has expired, or (iii) the use
of any prospectus after such time as the Company has advised the Eligible Holder
that the filing of a post-effective amendment or supplement thereto is required,
except such prospectus as so amended or supplemented.

               (c)  With  respect  to the  indemnities  provided  above  in this
Section 4.6, an indemnified  party shall, with respect to any claim made against
such indemnified  party,  notify the indemnifying party in writing of the nature
of the  claim as soon as  practicable  but not more  than  ten  days  after  the
indemnified party shall have received notice of the assertion thereof before any
court or  governmental  authority.  The failure by an indemnified  party to give
notice as provided in the foregoing  sentence shall not relieve the indemnifying
party of its  obligations  under  this  section  except to the  extent  that the
failure  results in the failure of actual notice to the  indemnifying  party and
the  indemnifying  party is  damaged  solely as a result of the  failure to give
notice.  Upon  receipt of notice by an  indemnifying  party from an  indemnified
party of the assertion of any such claim,  the  indemnifying  party shall employ
counsel  reasonably  acceptable  to the  indemnified  party and shall assume the
defense of such  claim.  The  indemnified  party  shall have the right to employ
separate  counsel and to participate  in (but not control) any such action,  but
the fees and expenses of such counsel  shall be the expense of such  indemnified
party unless (i) the  employment of counsel by such  indemnified  party has been
authorized by the indemnifying party, (ii) the indemnified party shall have been
advised by its counsel in writing  that there is a conflict of interest  between
the indemnifying  party and the indemnified  party in the conduct of the defense
of such action (in which case the indemnifying party shall not have the right to
direct the defense of such action on behalf of the  indemnified  party) or (iii)
the  indemnifying  party shall not in fact have  employed  counsel to assume the
defense of such  action,  in each of which  cases the fees and  expenses of such
counsel shall be at the expense of the indemnifying party. An indemnifying party
shall not be liable for any settlement of an action effected without its written
consent  (which consent shall not be  unreasonably  withheld).  No  indemnifying
party will consent to entry of any judgment or enter into any  settlement  which
does not include as an unconditional  term thereof the giving by the claimant or
plaintiff to such  indemnified  party of a release from all liability in respect
of such action.

SECTION 5 ADDITIONAL AGREEMENTS

          5.1 Confidentiality.

               (a) Each Consenting Stockholder agrees that it will not, directly
or indirectly, without the prior written consent of the Company, use or disclose
to any person, firm or corporation, any information, trade secrets, confidential
customer  information,  technical  data or know-how  relating  to the  products,
processes, methods, equipment or business practices of the Company or any of its
Subsidiaries,  except  (a) to the  extent  any of the  foregoing  is or  becomes
available to the public other than as a result of disclosure by such  Consenting
Stockholder  or any of its  Affiliates or the  directors,  officers,  employees,
agents, advisors and controlling persons of it or any of its Affiliates,  (b) as
necessary to effect a transaction  under and in compliance  with Section 3 or 4,
(c) as may be required by law and (d) as any Consenting Stockholder may disclose
to its lenders,  rating agencies and business,  legal and financial advisors. In
the event any Consenting Stockholder is required by applicable law or regulation
or by legal  process to  disclose  any of the  foregoing,  it will  provide  the
Company and other Consenting  Stockholders  with prompt notice thereof to enable
them to seek an appropriate protective order. The covenants made by a Consenting
Stockholder  in this  Section  5.1 shall  continue  to apply for a period of two
years after such Consenting Stockholder ceases to be a Consenting Stockholder.

               (b) At any time  that the  Continental  Merger  Agreement  or any
other agreement with respect to a U S West Transaction is in effect,  and at any
time after the consummation of the U S West  Transaction,  the Company shall not
provide to Continental,  and Continental shall not request from the Company, any
strategic  or  confidential   information  about  the  Company  or  any  of  its
Subsidiaries or Affiliates (other than annual and quarterly financial statements
prepared by the Company);  provided, however, that, notwithstanding this Section
5.1(b),  a director of the Company who was an Agreed  Nominee  designated by the
Consenting  Stockholder  Group that  includes  Continental  shall be entitled to
receive any  information  that is furnished to the  directors of the Company (in
their capacities as directors of the Company) to the extent that a director of a
Delaware   corporation  is  entitled  to  such  information  under  the  General
Corporation Law of Delaware.

          5.2 Issuance of Additional  Class B Common Stock.  Without the consent
of each  Designating  Stockholder,  the Company  shall not issue any  additional
shares of Class B Common Stock other than shares of Class B Common Stock issued:

               (a) in connection with a stock split;

                                     - 39 -

          6.4 Entire Agreement. As of the date hereof, this Agreement,  together
with the Supplemental Agreement and the Reorganization Agreement, represents the
entire  understanding  of the parties  with  reference  to the matters set forth
herein. This Agreement  supersedes,  from and after the date hereof with respect
to all periods  commencing on or after the date hereof, the Amended and Restated
Stockholders'  Agreement dated as of May 5, 1993, as amended,  among the Company
and the  Consenting  Stockholders,  and  all  prior  negotiations,  discussions,
correspondence,  communications  and prior agreements among the parties relating
to the subject matter herein. Neither the Company nor any Consenting Stockholder
shall have any rights  after the date of this  Agreement  under the  Amended and
Restated Stockholders' Agreement dated as of May 5, 1993, as amended.

          6.5 Amendment and Waiver.  Subject to Section 3.8, this  Agreement may
not be amended or  modified in any respect  except by an  instrument  in writing
signed by all of the parties  hereto.  Any failure of any party hereto to comply
with any obligation, covenant, agreement or condition contained herein may

                                     - 42 -


<PAGE>



be waived by the party or parties  entitled to the  benefits  thereof,  but such
waiver or  failure  to  insist  upon  strict  compliance  with such  obligation,
covenant,  agreement or condition  shall not operate as a waiver of, or estoppel
with respect to, any subsequent or other failure.

          6.6 Governing Law. This Agreement  shall be governed by, and construed
in accordance  with,  the laws of the State of Delaware  (without  regard to its
laws pertaining to conflicts of law) applicable to contracts  executed in and to
be performed entirely in such state.

          6.7 Severability.  If any term or other provision of this Agreement is
invalid,  illegal or  incapable  of being  enforced by any rule of law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the  economic or legal  substance  of
the  transactions  contemplated  hereby is not affected in any manner adverse to
any party. Upon such  determination that any term or other provision is invalid,
illegal or incapable of being  enforced,  the parties hereto shall  negotiate in
good faith to modify this  Agreement so as to effect the original  intent of the
parties as  closely  as  possible  in an  acceptable  manner to the end that the
transactions contemplated hereby are fulfilled to the greatest extent possible.

          6.8 Consent to Jurisdiction; Specific Performance.

               (a) Each Consenting Stockholder hereby irrevocably submits to the
non-exclusive  jurisdiction of any Delaware State or Federal court in any action
or proceeding arising out of or relating to this Agreement,  and each Consenting
Stockholder  hereby irrevocably agrees that all claims in respect of such action
or proceeding  may be heard and  determined  in such  Delaware  State or Federal
court. Each Consenting  Stockholder  hereby  irrevocably  waives, to the fullest
extent it may  effectively  do so, the defense of an  inconvenient  forum to the
maintenance of such action or proceeding.

               (b)  Nothing in this  Section  6.8 shall  affect the right of any
party to serve legal process in any other manner  permitted by law or affect the
right of any party to bring any action or proceeding  against any other party or
its  property  in the  courts  of  any  other  jurisdictions.  The  consents  to
jurisdiction set forth in this Section 6.8 shall not constitute general consents
to service of  process  in the State of  Delaware,  shall have no effect for any
purpose except as provided in this Section 6.8 and shall not be deemed to confer
rights on any Person other than the parties to this Agreement.

               (c) Without  intending to limit the remedies  available to any of
the parties hereto, each of the parties

                                     - 43 -


<PAGE>



hereto  acknowledges  and agrees that a  violation  by such party of any term of
this Agreement will cause the other parties hereto  irreparable injury for which
an adequate remedy at law is not available.  Therefore, the parties hereto agree
that each such party shall be entitled to an  injunction,  restraining  order or
other  form of  equitable  relief  from  any  court  of  competent  jurisdiction
restraining  any other party  hereto from  committing  any breach or  threatened
breach  of,  or  otherwise  specifically  to  enforce,  any  provision  of  this
Agreement.

          6.9  Counterparts.  This  Agreement  may be  executed  in one or  more
counterparts,  each of  which  shall  be an  original,  but all of  which  taken
together shall constitute one and the same agreement.

          6.10  Headings.  The section  headings used in this  Agreement are for
reference  purposes only and shall not affect the meaning or  interpretation  of
any term or provision of this Agreement.

                                     - 44 -
