                               TCI WIRELINE, INC.


                        OPTION TO PURCHASE COMMON STOCK


                 THIS AGREEMENT ("AGREEMENT") is made as of the 1st day of
December, 1996, by and among TCI WIRELINE, INC., a Delaware corporation (the
"COMPANY"), "GRANTEE" and, for purposes of paragraphs 11(b) and 11(c) only,
TELE-COMMUNICATIONS, INC., a Delaware corporation ("TCI").

                 The Company is on the date hereof a subsidiary of TCI.  The
Board of Directors of the Company ("COMPANY BOARD") and the Board of Directors
of TCI have each determined that it is in the best interests of the Company to
grant Grantee the rights and option set forth herein in order to provide
Grantee with additional remuneration for services rendered to the Company and
its predecessors, to encourage Grantee to remain in the employ of TCI and/or
one or more of its Subsidiaries, including the Company, and to provide
additional incentive to Grantee by increasing Grantee's proprietary interest in
the continued success and progress of the Company. Capitalized terms used
herein and not otherwise defined are defined in paragraph 18 below.

                 Accordingly, the Company, Grantee and, for purposes of
paragraphs 11(b) and 11(c) only,  TCI hereby agree as follows:

         1.      GRANT OF OPTION; OPTION TERM.  The Company hereby grants to
Grantee the right and option (the "OPTION"), on the terms and subject to the
conditions set forth herein, to purchase the Option Shares from the Company for
a price per Option Share equal to the Option Price.  The Option Price and
Option Shares are subject to adjustment pursuant to paragraph 9 below.  Subject
to paragraph 2, the Option shall be exercisable in whole at any time and in
part from time to time during the period commencing on the date hereof and
expiring at 5:00 p.m., Denver, Colorado time ("CLOSE OF BUSINESS") on the tenth
anniversary of the Determination Date, or such earlier date as the Option may
be terminated pursuant to paragraph 6 or paragraph 9(c) (the "OPTION TERM").

         2.      CONDITIONS OF EXERCISE; VESTING.  Except as otherwise provided
in the last sentence of this paragraph 2 or in paragraph 9(c), the Option shall
not be exercisable until the first anniversary of the Determination Date, and,
from the first anniversary of the Determination Date to the fifth anniversary
of the Determination Date, the Option shall be exercisable only to the extent
the Option Shares have become available for purchase in accordance with the
following schedule:

</TABLE>

         Notwithstanding the foregoing, all Option Shares shall become
available for purchase if during the Option Term (i) Grantee's employment with
the TCI Group shall terminate by reason of (x) termination by the TCI Group
without Cause, (y) termination by Grantee for Good Reason or (z) Disability,
(ii) Grantee's employment shall terminate pursuant to provisions of a written
employment agreement, if any, between Grantee and the applicable member(s) of
the TCI Group which expressly permits Grantee to terminate such employment upon
the occurrence of specified events (other than the giving of notice and passage
of time) or (iii) Grantee dies while employed by the TCI Group.  A change of
employment is not a termination of employment within the meaning of this
paragraph 2, provided that, after giving effect to such change, Grantee is an
employee of, or becomes or continues to be a consultant to, any member of the
TCI Group.

         3.      MANNER OF EXERCISE.  The Option may be exercised only by
delivering to the Company all of the following and shall be considered
exercised (as to the number of shares specified in the notice referred to in
clause (a) below)) on the later of (i) the first business day on which the
Company has received all of the following deliveries and (ii) the date of
exercise designated in the written notice referred to in clause (a) below (or
if such date is not a business day, the first business day thereafter):

                 (a)      written notice, in such form as the Company Board may
         reasonably require, stating that Grantee is exercising the Option and
         setting forth the date of such exercise, the number of Option Shares
         to be purchased, the aggregate Option Price to be paid for such Option
         Shares in accordance with this Agreement and the manner in which such
         payment is being made ("OPTION EXERCISE NOTICE");

                 (b)      payment of the Option Price for each Option Share to
         be purchased upon such exercise, in cash or in such other form or
         combination of forms of payment contemplated by paragraph 10, together
         with payment of, or other provision acceptable to the Company Board
         for, any and all withholding taxes required to be withheld by the
         Company upon such exercise, in accordance with paragraph 4;

                 (c)      any other documentation that the Company Board may
         reasonably require (including, without limitation, proof satisfactory
         to the Company Board that the Option is then exercisable for the
         number of Option Shares set forth in such notice); and





                                       2
<PAGE>   3
                 (d)      evidence satisfactory to the Company Board that
         Grantee is validly and simultaneously exercising the same proportion
         of the stock option granted to him by TCI Telephony Services, Inc.
         pursuant to that certain option agreement, dated as of the date
         hereof, among TCI Telephony Services, Inc., Grantee and TCI, as the
         same may hereafter be amended, modified or supplemented from time to
         time or, if said stock option has been superseded by the option
         contemplated by Exhibit B to said option agreement, then evidence
         satisfactory to the Company Board that Grantee is simultaneously
         exercising the same proportion of the latter option.

         4.      WITHHOLDING FOR TAXES.  It shall be a condition precedent to
any exercise of the Option that Grantee make provision acceptable to the
Company for the payment or withholding of any and all federal, state and local
taxes required to be withheld by the Company to satisfy the tax liability
associated with such exercise, as determined by the Company Board.

         5.      DELIVERY BY THE COMPANY.  As soon as practicable after receipt
of all the items required by paragraph 3 with respect to any exercise of the
Option, and subject to the withholding referred to in paragraph 4, the Company
shall deliver or cause to be delivered to Grantee certificates issued in
Grantee's name for the number of whole Option Shares purchased upon such
exercise.  If delivery is by mail, delivery of Option Shares shall be deemed
effected for all purposes when the Company or a stock transfer agent of the
Company shall have deposited the certificates in the United States mail,
addressed to Grantee, and any cash payment (for fractional shares or otherwise)
shall be deemed effected when a Company check, payable to Grantee and in an
amount equal to the amount of the cash payment, shall have been deposited in
the United States mail, addressed to Grantee, in each case in accordance with
paragraph 12.

         6.      EARLY TERMINATION OF OPTION.  Unless otherwise determined by
the Company Board in its sole discretion, the Option shall terminate, prior to
the expiration of the ten-year period provided for in paragraph 1, as follows:

                 (a)      If Grantee's employment with the TCI Group terminates
         other than (i) by Grantee with Good Reason, (ii) by reason of
         Grantee's death or Disability,  (iii) with the written consent of the
         applicable member(s) of the TCI Group, (iv) without such consent if
         such termination is pursuant to provisions of a written employment
         agreement, if any, between Grantee and the applicable member(s) of the
         TCI Group which expressly permits Grantee to terminate such employment
         upon the occurrence of specified events (other than the giving of
         notice and passage of time), or (v) by the TCI Group with or without
         Cause, then the Option shall terminate at the Close of Business on the
         first business day following the expiration of the 90-day period
         beginning on the date of termination of Grantee's employment;

                 (b)      If Grantee dies while employed by the TCI Group, or
         prior to the expiration of a relevant period of time during which the
         Option remains exercisable as provided in this





                                       3
<PAGE>   4
         paragraph 6, the Option shall terminate at the Close of Business on
         the first business day following the expiration of the one-year period
         beginning on the date of death;

                 (c)      If Grantee's employment with the TCI Group terminates
         by reason of Disability, then the Option shall terminate at the Close
         of Business on the first business day following the expiration of the
         one-year period beginning on the date of termination of Grantee's
         employment;

                 (d)      If Grantee's employment with the TCI Group is
         terminated by the TCI Group for Cause, then the Option shall terminate
         immediately upon such termination of Grantee's employment; and

                 (e)      If Grantee terminates his employment with the TCI
         Group (i) with Good Reason,  (ii) with the written consent of the
         applicable member(s) of the TCI Group or (iii) pursuant to provisions
         of a written employment agreement, if any, between Grantee and the
         applicable member(s) of the TCI Group which expressly permits Grantee
         to terminate such employment upon the occurrence of specified events
         (other than the giving of notice and passage of time), or if the TCI
         Group terminates Grantee's employment with the TCI Group without
         Cause, then the Option Term shall not terminate prior to the end of
         the ten-year period provided for in paragraph 1, except as otherwise
         provided for in paragraph 6(b) or 9(c).

         In any event in which the Option remains exercisable for a period of
time following the date of termination of Grantee's employment as provided
above, the Option may be exercised during such period of time only to the
extent it was exercisable as provided in paragraph 2 or paragraph 9(c) on such
date of termination of Grantee's employment.  A change of employment is not a
termination of employment within the meaning of this paragraph 6, provided
that, after giving effect to such change, Grantee is an employee of, or becomes
or continues to be a consultant to, any member of the TCI Group.  Anything
contained herein to the contrary notwithstanding, the Option shall in any event
terminate upon the expiration of the ten-year period provided for in paragraph
1, if not theretofore terminated.

         7.      NONTRANSFERABILITY OF OPTION.  During Grantee's lifetime, the
Option is not and shall not be transferable (voluntarily or involuntarily)
other than pursuant to a Domestic Relations Order and, except as otherwise
required pursuant to a Domestic Relations Order, is exercisable only by Grantee
or Grantee's court appointed legal representative.  Grantee may designate a
beneficiary or beneficiaries to whom the Option shall pass upon Grantee's death
and may change such designation from time to time by filing a written
designation of beneficiary or beneficiaries with the Company on the form
annexed hereto as Exhibit A or such other form as may be prescribed by the
Company Board, provided that no such designation shall be effective unless so
filed prior to the death of Grantee.  If no such designation is made or if the
designated beneficiary does not survive Grantee's death, the Option shall pass
by will or the laws of descent and distribution.  Following Grantee's death,
the Option, if otherwise exercisable, may be exercised by the person to whom
the Option





                                       4
<PAGE>   5
passes according to the foregoing, and such person shall be deemed to be
Grantee for purposes of any applicable provisions of this Agreement.

         8.      NO SHAREHOLDER RIGHTS; NO GUARANTEE OF EMPLOYMENT.  (a)
Grantee shall not be deemed for any purpose to be, or to have any of the rights
of, a stockholder of the Company with respect to any Option Shares unless and
until such Option Shares have been issued to Grantee by the Company.  The
existence of this Agreement or the Option shall not affect in any way the right
or power of the Company or its stockholders to accomplish any corporate act.

                 (b)      Nothing contained in this Agreement, and no action by
the Company or the Company Board with respect hereto, shall confer or be
construed to confer on Grantee any right to continue in the employ of the TCI
Group or any member thereof or interfere in any way with the right of TCI, the
Company or any employing member of the TCI Group to terminate Grantee's
employment at any time, with or without Cause, except as otherwise expressly
provided in any written employment agreement between the applicable member(s)
of the TCI Group and Grantee.

         9.      ADJUSTMENTS; ACCELERATION.  (a) If, after December 31, 1996,
the Company (i) pays a dividend or makes a distribution on the Company Common
Stock in shares of Company Common Stock; (ii) subdivides the outstanding shares
of Company Common Stock into a greater number of shares or (iii) combines the
outstanding shares of Company Common Stock into a smaller number of shares,
then this Option and the number of Option Shares and the Option Price per share
in effect immediately prior to the opening of business on the record date for
such dividend or distribution or the effective date of such subdivision or
combination shall be adjusted so that Grantee upon exercise thereafter of the
Option may receive the number of shares of Company Common Stock that Grantee
would have owned immediately following such event if Grantee had exercised the
Option immediately prior to the record date for, or effective date of, as the
case may be, such event. The adjustment contemplated by the preceding sentence
shall be made successively whenever any event listed above shall occur.  For a
dividend or distribution, the adjustment shall become effective immediately
after the record date for the dividend or distribution.  For a subdivision or
combination, the adjustment shall become effective immediately after the
effective date of the subdivision or combination.

                 (b)      The Option shall also be subject to adjustment
(including, without limitation, as to the number of Option Shares and the
Option Price per share) in the sole discretion of the Company Board and in such
manner as the Company Board may deem equitable and appropriate in connection
with the occurrence of any of the following events after December 31, 1996 that
affects the Company Common Stock such that an adjustment would be required in
order to preserve the benefits or potential benefits intended to be made
available under this Agreement: any dividend or distribution on the Company
Common Stock in shares of the Company's capital stock (other than Company
Common Stock); any reclassification of the Company Common Stock into shares of
the Company's capital stock (other than a reclassification by way of an
Approved Transaction); any extraordinary cash dividend; any distribution of any
rights, warrants or options to holders of Company Common Stock; any
distribution of any assets or debt securities (other than cash dividends





                                       5
<PAGE>   6
or distributions that are not extraordinary cash dividends); any
recapitalization, reorganization, split up or spin off; and any merger,
consolidation or binding share exchange that reclassifies or changes the
outstanding Company Common Stock or other similar corporate event (other than
those which constitute Approved Transactions).  Notwithstanding the foregoing,
in the event of any reclassification or recapitalization of the Company Common
Stock into two or more classes or series of common stock with different voting
rights (however the same may be effected), no adjustment to the Option shall be
required that would entitle Grantee to receive shares of any class or series of
common stock of the Company other than the class or series with the fewest
number of votes per share.  Adjustments to the Option Price shall be made on a
per share basis so that the aggregate remaining Option Price is unchanged.

                 (c)      The Company Board may at any time in its sole
discretion determine that the Option shall become exercisable in full, without
regard to paragraph 2, whether immediately, upon the occurrence of specified
events, or otherwise.  Without limiting the generality of the foregoing, in the
event of any Board Change, Control Purchase or Approved Transaction that occurs
with respect to TCI following December 31, 1996 and prior to the earlier of
such time as the Company ceases to be a Subsidiary of TCI or such time as the
Company becomes a Public Company, the Option shall become exercisable in full,
without regard to paragraph 2, effective upon the Board Change or Control
Purchase or immediately prior to consummation of the Approved Transaction, as
applicable (or at such earlier time as the Company Board in its sole discretion
may determine); provided, however, that to the extent not theretofore exercised
the Option shall terminate upon the first to occur of the consummation of the
Approved Transaction or the expiration or early termination of the Option Term.
In the event that (i) at any time after December 31, 1996 while the Company is
a Subsidiary of TCI, an Approved Transaction occurs with respect to the Company
after giving effect to which the Company will cease to be a Subsidiary of TCI
or (ii) an Approved Transaction, Board Change or Control Purchase occurs with
respect to the Company at a time following December 31, 1996 that the Company
is no longer a Subsidiary of TCI, then, in any such case,  the Option shall
become exercisable in full, without regard to paragraph 2, effective upon the
Board Change or Control Purchase or immediately prior to consummation of the
Approved Transaction, as applicable (or at such earlier time as the Company
Board in its sole discretion may determine); provided, however, that to the
extent not theretofore exercised the Option shall terminate upon the first to
occur of the consummation of the Approved Transaction or the expiration or
early termination of the Option Term.  Notwithstanding the foregoing, the
Company Board may, in its discretion, determine that the Option will not become
exercisable on an accelerated basis in connection with an Approved Transaction
and/or will not terminate if not exercised prior to consummation of the
Approved Transaction, if the Board or the surviving or acquiring corporation,
as the case may be, shall have taken or made effective provision for the taking
of such action as in the opinion of the Company Board is equitable and
appropriate to substitute a new stock option for the Option evidenced by this
Agreement or to assume this Agreement and the Option evidenced hereby and in
order to make such new or assumed stock option, as nearly as may be
practicable, equivalent to the Option evidenced by this Agreement as then in
effect (but before giving effect to any acceleration of the exercisability
hereof unless otherwise determined by the Company Board), taking into account,
to the extent applicable, the kind and amount of securities, cash or other
assets





                                       6
<PAGE>   7
into or for which the Company Common Stock may be changed, converted or
exchanged in connection with the Approved Transaction.

                 (d)      All actions taken by the Company Board with respect
to the Option pursuant to this paragraph 9 shall be consistent with any actions
taken by the Company Board with respect to the Other Options.  When an
adjustment to the Option pursuant to paragraph 9(a) or 9(b) becomes effective
immediately after the record date for an event, the Company may defer until the
occurrence of such event issuing to Grantee the additional shares of Company
Common Stock (or cash, securities or other property) issuable or deliverable
upon any exercise of the Option after such record date and before the
occurrence of such event by reason of the adjustment required by such event
over and above the shares of Company Common Stock that would have been issuable
upon such exercise absent such adjustment.

         10.     MANNER OF PAYMENT.  The method or methods of payment of the
Option Price for the shares of Company Common Stock to be purchased upon
exercise of the Option and any amounts required by paragraph 4 shall consist of
(i) cash, (ii) check, (iii) promissory note in such form and with such security
as shall be acceptable to the Company Board in its sole discretion (except that
this method of payment will not be available for amounts required by paragraph
4), (iv) whole shares of Company Common Stock already owned by Grantee, (v) the
withholding of shares of Company Common Stock issuable upon exercise of the
Option, (vi) the delivery, together with a properly executed exercise notice,
of irrevocable instructions to a broker to deliver promptly to the Company the
amount of sale or loan proceeds required to pay the purchase price (except that
this method of payment will not be available until the Company is a Public
Company), or (vii) any combination of the foregoing methods of payment, as
Grantee may elect and shall designate in the Option Exercise Notice, subject,
however, to any restrictions or limitations of applicable law or of any
agreement evidencing indebtedness of the Company for borrowed money.   Any
shares of Company Common Stock delivered or withheld in payment of any amount
due hereunder shall be valued for such purposes (i) if the Option is exercised
prior to such time as the Company is a Public Company, at the Appraised Public
Trading Value of such shares on the applicable date of exercise of the Option,
determined as provided in paragraph 11(c), and (ii) if the Option is exercised
when the Company is a Public Company, at the Fair Market Value of such shares
on the applicable date of exercise of the Option.

         11.     RESTRICTIONS IMPOSED BY LAW; CERTAIN PUT RIGHTS; APPRAISAL
PROCEDURES. (a) Grantee acknowledges that neither the Option nor any of the
Option Shares has been registered under the Securities Act of 1933 and that the
Option Shares may not be transferred in the absence of such registration or the
availability of an exemption therefrom under such Act or the rules and
regulations of the Securities and Exchange Commission promulgated thereunder.
Neither the Company nor any other person shall have any obligation to register
any Option Shares, or any transfer of Option Shares, under the Securities Act
of 1933, the Exchange Act or any other state or federal securities law.
Certificates representing Option Shares purchased by Grantee hereunder may bear
such restrictive and other legends as counsel for the Company shall require in
order to insure compliance with any such law or any rule or regulation
promulgated thereunder.  Grantee agrees that Grantee





                                       7
<PAGE>   8
will not exercise the Option (and that the Company shall not be obligated to
deliver any Option Shares upon any exercise of the Option) if counsel for the
Company determines that such exercise or delivery would violate any applicable
law or any rule or regulation of any governmental authority, or any rule or
regulation of, or agreement of the Company with, any securities exchange or
association upon which the Company Common Stock is listed or quoted.  The
Company shall in no event be obligated to take any affirmative action in order
to cause the exercise of the Option or the resulting delivery of the shares of
Company Common Stock to comply with any such law, rule, regulation or
agreement.  Without limiting the generality of the foregoing, but subject to
paragraph 11(b), Grantee acknowledges and agrees that unless and until the
Company becomes a Public Company or, if earlier, ceases to be a Subsidiary of
TCI, the Option Shares may not be transferred to any person (other than to
Grantee's designated beneficiary pursuant to paragraph 7 upon Grantee's death)
without the prior written consent of TCI.

                 (b)      In the event that the Company has not become a Public
Company on or before February 1, 2001, Grantee shall have the right, by written
notice given to TCI at any time thereafter, to require TCI to purchase all, and
not less than all, the Option Shares for a purchase price equal to the
Appraised Public Trading Value of the Option Shares determined as provided in
paragraph 11(c) (the "PUT RIGHT"); provided, however, that the Put Right shall
expire upon the first to occur of the Company's becoming a Public Company and
the Company's ceasing to be a Subsidiary of TCI; and, provided, further, that
if Grantee dies prior to February 1, 2001, the Put Right shall become
exercisable by his beneficiary or beneficiaries pursuant to paragraph 7 or his
heirs, devisees or distributees, as applicable, from and after the date of
Grantee's death.  Grantee's notice of the exercise of his Put Right (the "PUT
EXERCISE NOTICE") shall set forth the number of Option Shares then owned by
Grantee and/or that remain subject to the Option and shall contain the
information required by paragraph 11(c).  In the event that any Option Shares
remain subject to the Option, Grantee shall exercise the balance of the Option
in full prior to the closing of the purchase pursuant to the Put Right.  If the
Put Right is exercised, TCI shall have the right to pay the purchase price for
the Option Shares in cash, shares of Tele-Communications, Inc. Series A TCI
Group Common Stock, $1.00 par value per share, or any successor class or series
of TCI's common stock, or if any class or series of TCI's common stock is
hereafter created that is intended to track the separate performance of
specified assets or businesses of TCI that include assets and businesses of the
Company, shares of such class or series (and if more than one series of such
"tracking stock" is created with different voting rights, the series with the
lower voting rights) (collectively the "TCI STOCK"), or any combination of cash
and shares of TCI Stock as TCI may elect.  If TCI elects to pay all or any
portion of the purchase price for the Option Shares in shares of TCI Stock,
said shares shall be valued for such purpose on the basis of the average of the
daily Closing Prices of the TCI Stock during the period of 10 consecutive
trading days commencing 20 trading days prior to the closing of such purchase.
The closing of the purchase of the Option Shares pursuant to this paragraph
11(b) shall occur on the 10th day following the receipt by Grantee and TCI of
notice pursuant to paragraph 11(c) of the final determination of the Appraised
Public Trading Value of the Option Shares (or on such other date as the parties
may agree).  At the closing, if TCI has elected to pay all or a portion of the
purchase price in shares of TCI Stock, it shall enter into a registration
rights agreement with Grantee, providing Grantee registration rights with
respect to the shares so delivered on the terms and subject to the conditions
contained in TCI's standard form of such agreement with such variations as the
parties agree.

                 (c)      Grantee's Put Exercise Notice and any Option Exercise
Notice that provides for the delivery or withholding of shares of Company
Common Stock as a manner of payment of the Option Price or of amounts required
under paragraph 4 shall identify the Public Appraiser selected by Grantee to
make the determination of Appraised Public Trading Value ("FIRST APPRAISER").
Within 10 days after receipt of the Put Exercise Notice or Option Exercise
Notice, as applicable, TCI or the Company, as applicable, shall notify Grantee
in writing of the Applicable Person's selection of a Public Appraiser (the
"SECOND APPRAISER").  The First Appraiser and the Second Appraiser shall each
submit its determination of the Appraised Public Trading Value of the Option
Shares to Grantee and the Applicable Person within 30 days of the date of its
selection.  If the respective determinations of Appraised Public Trading Value
by such Public Appraisers vary by less than 10% of the higher determination,
then the Appraised Public Trading Value shall be the average of the two
determinations.  If such determinations vary by ten (10%) or more of the higher
determination, the two Public Appraisers shall promptly designate a third
Public Appraiser (the "THIRD APPRAISER").  Neither Grantee nor the Applicable
Person shall provide, and the First Appraiser and Second Appraiser shall be
instructed not to provide, any information to the Third Appraiser as to the
determination of the First Appraiser and Second Appraiser or otherwise
influence such Third Appraiser's determination.  The Third Appraiser shall
submit its determination of the Appraised Public Trading Value to Grantee and
the Applicable Person within 30 days of the date of its selection.  The
Appraised Public Trading Value shall be equal to the average of the two closest
of the three determinations, provided 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, the Appraised
Public Trading Value shall be equal to the middle determination.  The Public
Appraisers shall jointly notify the Applicable Person and Grantee in writing of
their final determination of the Appraised Public Trading Value of the Option
Shares within five (5) days thereafter.  Grantee and the Applicable Person
shall each pay the fees and expenses of his or its own Public Appraiser and
one-half of the fees and expenses of the Third Appraiser, if any.
