</Table>

Notwithstanding the foregoing, (i) all L Options will become exercisable on the
date of the Grantee's termination of employment if (A) the Grantee's employment
with the Company and its Subsidiaries terminates by reason of Disability or (B)
the Grantee dies while employed by the Company or a Subsidiary, and (ii) if the
Grantee's employment with the Company and its Subsidiaries is terminated by the
Company or a Subsidiary without Cause (as determined in the sole discretion of
the Committee), any L Options that otherwise would become exercisable during the
remainder of the calendar year in which the Grantee's employment with the
Company and its Subsidiaries is terminated will become exercisable on the date
of the Grantee's termination of employment.

     (b) To the extent the L Options become exercisable, such L Options may be
exercised in whole or in part (at any time or from time to time, except as
otherwise provided herein) until expiration of the Term or earlier termination
thereof.

     (c) The Grantee acknowledges and agrees that the Committee, in its
discretion and as contemplated by Section 3.3 of the Plan, may adopt rules and
regulations from time to time after the date hereof with respect to the exercise
of the L Options and that the exercise by the Grantee of L Options will be
subject to the further condition that such exercise is made in accordance with
all such rules and regulations as the Committee may determine are applicable
thereto.

     4. MANNER OF EXERCISE. L Options will be considered exercised (as to the
number of L Options specified in the notice referred to in Section 4(a) below)
on the latest of (i) the date of exercise designated in the written notice
referred to in Section 4(a) below, (ii) if the date so designated is not a
Business Day, the first Business Day following such date or (iii) the earliest
Business Day by which the Company has received all of the following:

     (a) Written notice, in such form as the Committee may require, containing
such representations and warranties as the Committee may require and
designating, among other things, the date of exercise and the number of shares
of L Stock ("Option Shares") to be purchased;

                                       3
<Page>

     (b) Payment of the Base Price for each Option Share to be purchased in any
(or a combination) of the following forms: (A) cash, (B) check or (C) 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 (and, if applicable the
Required Withholding Amount, as described in Section 5 below); and

     (c) Any other documentation that the Committee may reasonably require.

     5. MANDATORY WITHHOLDING FOR TAXES. The Grantee acknowledges and agrees
that the Company will deduct from the shares of L Stock otherwise payable or
deliverable upon exercise of any L Options that number of shares of L Stock
(valued at their Fair Market Value on the date of exercise) that is equal to the
amount of all federal, state and local taxes required to be withheld by the
Company upon such exercise, as determined by the Committee (the "Required
Withholding Amount"). If the Grantee elects to make payment of the Base Price by
delivery 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,
such instructions may also include instructions to deliver the Required
Withholding Amount to the Company. In such case, the Company will notify the
broker promptly of the Committee's determination of the Required Withholding
Amount.

     6. PAYMENT OR DELIVERY BY THE COMPANY. As soon as practicable after receipt
of all items referred to in Section 4, and subject to the withholding referred
to in Section 5, the Company will deliver or cause to be delivered to the
Grantee certificates issued in the Grantee's name for the number of shares of L
Stock purchased by exercise of L Options, and (ii) any cash payment to which the
Grantee is entitled in lieu of a fractional share of L Stock, as provided in
Section 2 above. Any delivery of shares of L Stock will be deemed effected for
all purposes when certificates representing such shares have been delivered
personally to the Grantee or, if delivery is by mail, when the stock transfer
agent of the Company has deposited the certificates in the United States mail,
addressed to the Grantee, and any cash payment will be deemed effected when a
check from the Company, payable to the Grantee and in the amount equal to the
amount of the cash payment, has been delivered personally to the Grantee or
deposited in the United States mail, addressed to the Grantee.

     7. EARLY TERMINATION OF L OPTIONS. Unless otherwise determined by the
Committee in its sole discretion, the L Options will terminate, prior to the
expiration of the Term, at the time specified below:(a) Subject to Section 7(b),
if the Grantee's employment with the Company and its Subsidiaries is terminated
other than (i) by the Company or a Subsidiary (whether for Cause or without
Cause) or (ii) by reason of death or Disability, then the L Options will
terminate at the Close of Business on the first Business Day following the
expiration of the 90-day period which began on the date of termination of the
Grantee's employment.

     (b) If the Grantee dies (i) while employed by the Company or a Subsidiary,
or prior to the expiration of a period of time following termination of the
Grantee's employment during which the L Options remain exercisable as provided
in Section 7(a) or Section 7(c), as

                                       4
<Page>

applicable, the L Options will terminate at the Close of Business on the first
Business Day following the expiration of the one-year period which began on the
date of the Grantee's death, or (ii) prior to the expiration of a period of time
following termination of the Grantee's employment during which the L Options
remain exercisable as provided in Section 7(d), the L Options will terminate at
the Close of Business on the first Business Day following the expiration of (A)
the one-year period which began on the date of the Grantee's death or (B) the
Special Termination Period, whichever period is longer.

     (c) Subject to Section 7(b), if the Grantee's employment with the Company
and its Subsidiaries terminates by reason of Disability, then the L Options will
terminate at the Close of Business on the first Business Day following the
expiration of the one-year period which began on the date of termination of the
Grantee's employment.

     (d) If the Grantee's employment with the Company and its Subsidiaries is
terminated by the Company or a Subsidiary without Cause (as determined in the
sole discretion of the Committee), the L Options will terminate at the Close of
Business on the first Business Day following the expiration of the Special
Termination Period. The Special Termination Period is the period of time
beginning on the date of the Grantee's termination of employment and continuing
for the number of days that is equal to the sum of (a) 90, plus (b) 180
multiplied by the Grantee's total Years of Continuous Service. A Year of
Continuous Service means a consecutive 12-month period, measured by the
Grantee's hire date (as reflected in the payroll records of the Company or a
Subsidiary) and the anniversaries of that date, during which the Grantee is
employed by the Company or a Subsidiary without interruption. For purposes of
determining the Grantee's Years of Continuous Service, Grantee's employment with
the Company's former parent, AT&T Broadband LLC, formerly known as
Tele-Communications, Inc. ("TCI"), and any predecessor of the Company or TCI
will be included, provided that the Grantee's hire date with the Company or a
Subsidiary occurred within 30 days following the Grantee's termination of
employment with TCI or such predecessor. If the Grantee was employed by a
Subsidiary at the time of such Subsidiary's acquisition by the Company, the
Grantee's employment with the Subsidiary prior to the acquisition date will not
be included in determining the Grantee's Years of Continuous Service unless the
Committee, in its sole discretion, determines that such prior employment will be
included.

     (e) If the Grantee's employment with the Company and its Subsidiaries is
terminated by the Company for Cause, then the L Options will terminate
immediately upon such termination of the Grantee's employment.

     In any event in which L Options remain exercisable for a period of time
following the date of termination of the Grantee's employment as provided above,
the L Options may be exercised during such period of time only to the extent the
same were exercisable as provided in Section 3 above on such date of termination
of the Grantee's employment. Unless the Committee otherwise determines, a change
of the Grantee's employment from the Company to a Subsidiary or from one
Subsidiary to another Subsidiary will be a termination of employment within the
meaning of this Section 7. Notwithstanding any period of time referenced in this

                                       5
<Page>

Section 7 or any other provision of this Section 7 that may be construed to the
contrary, the L Options will in any event terminate upon the expiration of the
Term.

     8. NONTRANSFERABILITY. During the Grantee's lifetime, the L Options are not
transferable (voluntarily or involuntarily) other than pursuant to a Domestic
Relations Order and, except as otherwise required pursuant to a Domestic
Relations Order, are exercisable only by the Grantee or the Grantee's court
appointed legal representative. The Grantee may designate a beneficiary or
beneficiaries to whom the L Options will pass upon the Grantee's death and may
change such designation from time to time by filing a written designation of
beneficiary or beneficiaries with the Committee on the form annexed hereto as
Exhibit B or such other form as may be prescribed by the Committee, provided
that no such designation will be effective unless so filed prior to the death of
the Grantee. If no such designation is made or if the designated beneficiary
does not survive the Grantee's death, the L Options will pass by will or the
laws of descent and distribution. Following the Grantee's death, the L Options,
if otherwise exercisable, may be exercised by the person to whom such option or
right passes according to the foregoing and such person will be deemed the
Grantee for purposes of any applicable provisions of this Agreement.

     9. NO STOCKHOLDER RIGHTS. Prior to the exercise of L Options in accordance
with the terms and conditions set forth in this Agreement, the Grantee will 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 shares of L Stock, nor will the existence of
this Agreement affect in any way the right or power of the Company or any
stockholder of the Company to accomplish any corporate act, including, without
limitation, the acts referred to in Section 10.16 of the Plan.

     10. ADJUSTMENTS. If the outstanding shares of L Stock are subdivided into a
greater number of shares (by stock dividend, stock split, reclassification or
otherwise) or are combined into a smaller number of shares (by reverse stock
split, reclassification or otherwise), or if the Committee determines that any
stock dividend, extraordinary cash dividend, reclassification, recapitalization,
reorganization, split-up-spin-off, combination, exchange of shares, warrants or
rights offering to purchase any shares of L Stock, or other similar corporate
event (including mergers or consolidations other than those which constitute
Approved Transactions, which shall be governed by Section 10.1(b) of the Plan)
affects shares of L Stock such that an adjustment is required to preserve the
benefits or potential benefits intended to be made available under this
Agreement, then the L Options will be subject to adjustment (including, without
limitation, as to the number of L Options and the Base Price per share of such L
Options) in the sole discretion of the Committee and in such manner as the
Committee may deem equitable and appropriate in connection with the occurrence
of any of the events described in this Section 10 following the Vesting
Anniversary Date.

     11. RESTRICTIONS IMPOSED BY LAW. Without limiting the generality of Section
10.8 of the Plan, the Grantee will not exercise the L Options, and the Company
will not be obligated to make any cash payment or issue or cause to be issued
any shares of L Stock, if counsel to the Company determines that such exercise,
payment or issuance would violate any

                                       6
<Page>

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 shares of L Stock are listed or quoted. The Company
will in no event be obligated to take any affirmative action in order to cause
the exercise of the L Options or the resulting payment of cash or issuance of
shares of L Stock to comply with any such law, rule, regulation or agreement.

     12. NOTICE. Unless the Company notifies the Grantee in writing of a
different procedure, any notice or other communication to the Company with
respect to this Agreement will be in writing and will be delivered personally or
sent by United States first class mail, postage prepaid and addressed as

     13. AMENDMENT. Notwithstanding any other provision hereof, this Agreement
may be supplemented or amended from time to time as approved by the Committee as
contemplated in Section 10.7(b) of the Plan. Without limiting the generality of
the foregoing, without the consent of the Grantee,

     (a) this Agreement may be amended or supplemented from time to time as
approved by the Committee (i) to cure any ambiguity or to correct or supplement
any provision herein which may be defective or inconsistent with any other
provision herein, or (ii) to add to the covenants and agreements of the Company
for the benefit of the Grantee or surrender any right or power reserved to or
conferred upon the Company in this Agreement, subject to any required approval
of the Company's stockholders and, provided, in each case, that such changes or
corrections will not adversely affect the rights of the Grantee with respect to
the Award evidenced hereby, or (iii) to make such other changes as the Company,
upon advice of counsel, determines are necessary or advisable because of the
adoption or promulgation of, or change in or of the interpretation of, any law
or governmental rule or regulation, including any applicable federal or state
securities laws; and

     (b) subject to any required action by the Board or the stockholders of the
Company, the L Options granted under this Agreement may be canceled by the
Company and a new Award made in substitution therefor, provided that the Award
so substituted will satisfy all of the requirements of the Plan as of the date
such new Award is made and no such action will adversely affect any L Options to
the extent then exercisable.

any employing Subsidiary to terminate the Grantee's employment at any time, with
or without cause, subject to the provisions of any employment agreement between

Agreement, (i) no right or benefit under this Agreement will be subject to

</Table>

                                       2
<Page>

Notwithstanding the foregoing, (i) all L SARs will become exercisable on the
date of the Grantee's termination of employment if (A) the Grantee's employment
with the Company and its Subsidiaries terminates by reason of Disability or (B)
the Grantee dies while employed by the Company or a Subsidiary, and (ii) if the
Grantee's employment with the Company and its Subsidiaries is terminated by the
Company or a Subsidiary without Cause (as determined in the sole discretion of
the Committee), any L SARs that otherwise would become exercisable during the
remainder of the calendar year in which the Grantee's employment with the
Company and its Subsidiaries is terminated will become exercisable on the date
of the Grantee's termination of employment.

          (b) To the extent the L SARs become exercisable, such L SARs may be
exercised in whole or in part (at any time or from time to time, except as
otherwise provided herein) until expiration of the Term or earlier termination
thereof.

          (c) The Grantee acknowledges and agrees that the Committee may, in its
discretion and as contemplated by Section 3.3 of the Plan, adopt rules and
regulations from time to time after the date hereof with respect to the exercise
of the L SARs and that the exercise by the Grantee of L SARs will be subject to
the further condition that such exercise is made in accordance with all such
rules and regulations as the Committee may determine are applicable thereto.

     4. MANNER OF EXERCISE. L SARs will be considered exercised (as to the
number of L SARs specified in the notice referred to in Section 4(a) below) on
the latest of (i) the date of exercise designated in the written notice referred
to in Section 4(a) below, (ii) if the date so designated is not a Business Day,
the first Business Day following such date or (iii) the earliest Business Day by
which the Company has received all of the following:

          (a) Written notice, in such form as the Committee may require,
containing such representations and warranties as the Committee may require and
designating, among other things, the date of exercise and the number of L SARs
to be exercised; and

          (b) Any other documentation that the Committee may reasonably require.

     5. MANDATORY WITHHOLDING FOR TAXES. The Grantee acknowledges and agrees
that the Company will deduct from the shares of L Stock otherwise deliverable
upon exercise of any L SARs a number of shares of L Stock (valued at their Fair
Market Value on the date of exercise) that is equal to the amount of all
federal, state and local taxes required to be withheld by the Company upon such
exercise, as determined by the Company (the "Required Withholding Amount").

     6. DELIVERY BY THE COMPANY. As soon as practicable after receipt of all
items referred to in Section 4, and subject to the withholding referred to in
Section 5, the Company will deliver or cause to be delivered to the Grantee the
amount of consideration determined under the final sentence of Section 2 above,
which consideration shall consist of shares of L Stock (valued at their Fair
Market Value on the date of exercise), except as provided in the Plan with
respect to

                                       3
<Page>

fractional shares. Any delivery of shares of L Stock will be deemed effected for
all purposes when certificates representing such shares have been delivered
personally to the Grantee or, if delivery is by mail, when the stock transfer
agent of the Company has deposited the certificates in the United States mail,
addressed to the Grantee, and any cash payment will be deemed effected when a
check from the Company, payable to the Grantee and in the amount equal to the
amount of the cash payment, has been delivered personally to the Grantee or
deposited in the United States mail, addressed to the Grantee.

     7. EARLY TERMINATION OF L SARS. Unless otherwise determined by the
Committee in its sole discretion, the L SARs will terminate, prior to the
expiration of the Term, at the time specified below:

          (a) Subject to Section 7(b), if the Grantee's employment with the
Company and its Subsidiaries is terminated other than (i) by the Company or a
Subsidiary (whether for Cause or without Cause) or (ii) by reason of death or
Disability of the Grantee, then the L SARs will terminate at the Close of
Business on the first Business Day following the expiration of the 90-day period
which began on the date of termination of the Grantee's employment.

          (b) If the Grantee dies (i) while employed by the Company or a
Subsidiary, or prior to the expiration of a period of time following termination
of the Grantee's employment during which the L SARs remain exercisable as
provided in Section 7(a) or Section 7(c), as applicable, the L SARs will
terminate at the Close of Business on the first Business Day following the
expiration of the one-year period which began on the date of the Grantee's
death, or (ii) prior to the expiration of a period of time following termination
of the Grantee's employment during which the L SARs remain exercisable as
provided in Section 7(d), the L SARs will terminate at the Close of Business on
the first Business Day following the expiration of (A) the one-year period which
began on the date of the Grantee's death or (B) the Special Termination Period,
whichever period is longer.

          (c) Subject to Section 7(b), if the Grantee's employment with the
Company and its Subsidiaries terminates by reason of Disability, then the L SARs
will terminate at the Close of Business on the first Business Day following the
expiration of the one-year period which began on the date of termination of the
Grantee's employment.

          (d) If the Grantee's employment with the Company and its Subsidiaries
is terminated by the Company or a Subsidiary without Cause (as determined in the
sole discretion of the Committee), the L SARs will terminate at the Close of
Business on the first Business Day following the expiration of the Special
Termination Period. The Special Termination Period is the period of time
beginning on the date of the Grantee's termination of employment and continuing
for the number of days that is equal to the sum of (a) 90, plus (b) 180
multiplied by the Grantee's total Years of Continuous Service. A Year of
Continuous Service means a consecutive 12-month period, measured by the
Grantee's hire date (as reflected in the payroll records of the Company or a
Subsidiary) and the anniversaries of that date, during which the Grantee is
employed by the Company or a Subsidiary without interruption. For purposes of
determining the Grantee's Years of Continuous Service, Grantee's employment with
the Company's former parent, AT&T Broadband LLC, formerly known as
Tele-Communications, Inc. ("TCI"), and any predecessor of the Company or TCI
will be included, provided that the

                                       4
<Page>

Grantee's hire date with the Company or a Subsidiary occurred within 30 days
following the Grantee's termination of employment with TCI or such predecessor.
If the Grantee was employed by a Subsidiary at the time of such Subsidiary's
acquisition by the Company, the Grantee's employment with the Subsidiary prior
to the acquisition date will not be included in determining the Grantee's Years
of Continuous Service unless the Committee, in its sole discretion, determines
that such prior employment will be included.

          (e) If the Grantee's employment with the Company and its Subsidiaries
is terminated by the Company for Cause, then the L SARs will terminate
immediately upon such termination of the Grantee's employment.

     In any event in which L SARs remain exercisable for a period of time
following the date of termination of the Grantee's employment as provided above,
the L SARs may be exercised during such period of time only to the extent the
same were exercisable as provided in Section 3 above on such date of termination
of the Grantee's employment. Unless the Committee otherwise determines, a change
of the Grantee's employment from the Company to a Subsidiary or from one
Subsidiary to another Subsidiary will be a termination of employment within the
meaning of this Section 7. Notwithstanding any period of time referenced in this
Section 7 or any other provision of this Section 7 that may be construed to the
contrary, the L SARs will in any event terminate upon the expiration of the
Term.

     8. AUTOMATIC EXERCISE OF L SARS. Immediately prior to the termination of L
SARs as provided in Section 7(a), 7(b), 7(c) or 7(d) above or upon expiration of
the Term, all remaining L SARs then exercisable will be deemed to have been
exercised by the Grantee. Notwithstanding any other provision of this Agreement,
no exercise of LSARs will be deemed to occur upon termination of the Grantee's
employment for Cause.

     9. NONTRANSFERABILITY. During the Grantee's lifetime, L SARs are not
transferable (voluntarily or involuntarily) other than pursuant to a Domestic
Relations Order and, except as otherwise required pursuant to a Domestic
Relations Order, are exercisable only by the Grantee or the Grantee's court
appointed legal representative. The Grantee may designate a beneficiary or
beneficiaries to whom the L SARs will pass upon the Grantee's death and may
change such designation from time to time by filing a written designation of
beneficiary or beneficiaries with the Committee on the form annexed hereto as
Exhibit B or such other form as may be prescribed by the Committee, provided
that no such designation will be effective unless so filed prior to the death of
the Grantee. If no such designation is made or if the designated beneficiary
does not survive the Grantee's death, the L SARs will pass by will or the laws
of descent and distribution. Following the Grantee's death, the L SARs, if
otherwise exercisable, may be exercised by the person to whom such right passes
according to the foregoing and such person will be deemed the Grantee for
purposes of any applicable provisions of this Agreement.

     10. NO SToCKHOLDER RIGHTS. The Grantee will not, by reason of the Award
granted under this Agreement, be deemed for any purpose to be, or to have any of
the rights of, a stockholder of the Company or of the Company with respect to
any shares of L Stock, nor will the existence of this Agreement affect in any
way the right or power of the Company or its stockholders to accomplish any
corporate act, including, without limitation, the acts referred to in Section
11.16 of the Plan.

                                       5
<Page>

     11. ADJUSTMENTS. If the outstanding shares of L Stock are subdivided into a
greater number of shares (by stock dividend, stock split, reclassification or
otherwise) or are combined into a smaller number of shares (by reverse stock
split, reclassification or otherwise), or if the Committee determines that any
stock dividend, extraordinary cash dividend, reclassification, recapitalization,
reorganization, split-up-spin-off, combination, exchange of shares, warrants or
rights offering to purchase any L Stock, or other similar corporate event
(including mergers or consolidations other than those which constitute Approved
Transactions, which shall be governed by Section 11.1(b) of the Plan) affects
shares of L Stock such that an adjustment is required to preserve the benefits
or potential benefits intended to be made available under this Agreement, then
the L SARs will be subject to adjustment (including, without limitation, as to
the number of L SARs and the Base Price per share of such L SARs) in the sole
discretion of the Committee and in such manner as the Committee may deem
equitable and appropriate in connection with the occurrence of any of the events
described in this Section 11 following the Vesting Anniversary Date.

     12. RESTRICTIONS IMPOSED BY LAW. Without limiting the generality of Section
11.8 of the Plan, the Grantee will not exercise the L SARs , and the Company
will not be obligated to make any cash payment or issue or cause to be issued
any shares of L Stock, if counsel to the Company determines that such exercise,
payment or issuance 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 shares of L
Stock are listed or quoted. The Company will in no event be obligated to take
any affirmative action in order to cause the exercise of the L SARs or the
resulting payment of cash or issuance of L Stock to comply with any such law,
rule, regulation or agreement.

     13. NOTICE. Unless the Company notifies the Grantee in writing of a
different procedure, any notice or other communication to the Company with
respect to this Agreement will be in writing and will be delivered personally or
sent by United States first class mail, postage prepaid and addressed as
follows:

          Liberty Media Corporation

          Englewood, Colorado 80112

Agreement will be in writing and will be delivered personally, or will be sent

has received written notification from the Grantee of a change of address.

     14. AMENDMENT. Notwithstanding any other provision hereof, this Agreement
may be supplemented or amended from time to time as approved by the Committee as
contemplated in Section 11.7(b) of the Plan. Without limiting the generality of
the foregoing, without the consent of the Grantee,

                                       6
<Page>

approved by the Committee (i) to cure any ambiguity or to correct or supplement
any provision herein which may be defective or inconsistent with any other
provision herein, or (ii) to add to the covenants and agreements of the Company
for the benefit of the Grantee or surrender any right or power reserved to or
conferred upon the Company in this Agreement, subject to any required approval
of the Company's stockholders and, provided, in each case, that such changes or
corrections will not adversely affect the rights of the Grantee with respect to
the Award evidenced hereby, or (iii) to make such other changes as the Company,
upon advice of counsel, determines are necessary or advisable because of the
adoption or promulgation of, or change in or of the interpretation of, any law
or governmental rule or regulation, including any applicable federal or state
securities laws; and

          (b) subject to any required action by the Board or the stockholders of
the Company, the L SARs granted under this Agreement may be canceled by the
Company and a new Award made in substitution therefor, provided that the Award
so substituted will satisfy all of the requirements of the Plan as of the date
such new Award is made and no such action will adversely affect any L SARs to
the extent then exercisable.

     15. GRANTEE EMPLOYMENT. Nothing contained in this Agreement, and no action
of the Company or the Committee with respect hereto, will confer or be construed
to confer on the Grantee any right to continue in the employ of the Company or
any of its Subsidiaries or interfere in any way with the right of the Company or
any employing Subsidiary to terminate the Grantee's employment at any time, with
or without cause, subject to the provisions of any employment agreement between
the Grantee and the Company or any Subsidiary.

     16. NONALIENATION OF BENEFITS. Except as provided in Section 9 of this
Agreement, (i) no right or benefit under this Agreement will be subject to
anticipation, alienation, sale, assignment, hypothecation, pledge, exchange,
transfer, encumbrance or charge, and any attempt to anticipate, alienate, sell,
assign, hypothecate, pledge, exchange, transfer, encumber or charge the same
will be void, and (ii) no right or benefit hereunder will in any manner be
liable for or subject to the debts, contracts, liabilities or torts of the
Grantee or other person entitled to such benefits.

accordance with, the internal laws of the State of Colorado. Each party
irrevocably submits to the general jurisdiction of the state and federal courts
