discretion reasonably applied, such activities do not interfere with the
Employee's obligations under this Agreement, the Company is given prior
written notice of Employee's desire to engage in such activities, and to the
extent such business activities constitute a business opportunity of the
Company, the Company has elected not to pursue such activities.

     4.   COMPENSATION.

          (a)  BASE COMPENSATION. During the Term, the Company shall pay to
Employee a salary in the amount of $3,000.00 per month, subject to annual

and to the further qualifications set forth on Exhibit A hereto. During each
12 month period of Employee's employment Employee shall be entitled to two (2)
weeks of paid vacation.

          (c)  BONUS.  To the extent that the total annual compensation of
Employee for the initial four year Term is less than $51,000.00 per year,
Employee shall receive a bonus payment equal to the difference between the
actual annual compensation and $51,000.00. However, the bonus will be paid,
only if and to the extent that the Partnership repays all principal owing to

of $550,000.00, but which may reach $1,050,000.00.

     5. INVENTIONS AND PATENTS. Employee agrees that all intellectual property

Company's business, or are created with the use of the facilities or materials
of the Company.

     6.   CONFIDENTIALITY AND COMPETITIVE ACTIVITIES.

          (a)  CONFIDENTIALITY. In view of the fact that Employee's work with
the Company will bring him into close contact with many confidential affairs
of the Company, including matters of a business nature such as information
about costs, profits, markets, sales, trade secrets, potential patents and
other business ideas, customer lists, plans for future developments, business
opportunities, and information of any other kind not known within any industry
in which the Company operates (hereinafter, collectively, "Confidential
Matters"), Employee agrees:

               (i) To keep secret all Confidential Matters of the Company and
of any subsidiaries and affiliates of the Company and not to disclose them to
anyone outside of the Company or its subsidiaries or affiliates, or otherwise
use them or use his knowledge of them for his own benefit, including, without
limitation, use of the trade names or trademarks of the Company, either during
or after the Term, except with the Company's prior written consent; and

<PAGE>

               (ii) To deliver promptly to the Company at the termination of
the Term, or at any time the Company may request, all memoranda, notices,
records, reports and other documents (and all copies thereof) relating to the
business of the Company or any of its subsidiaries or affiliates, including,
but not limited to, Confidential Matters, which he may then possess or have
under his control.

          Notwithstanding any of the foregoing, the term "Confidential
Matters" does not include information which (i) Employee is compelled to
disclose by judicial or administrative process, or in the opinion of his
counsel, by other mandatory requirements of law, or (ii) is or becomes
generally available to the public other than as a result of any disclosure by
Employee.

     (b)  COMPETITIVE ACTIVITIES. During Employee's employment and for a
period of (i) six (6) months following the effective date of a termination of
Employee's employment "without cause", or as a result of his disability, (ii)
eighteen (18) months following the effective date of a termination of
Employee's employment in the event Employee resigns or is terminated for
Cause, Employee shall not, directly or indirectly, or through any subsidiary
or affiliate, own, consult, advise, manage, operate, join, or control, or
participate in the ownership, management, operation, or control of, or be
connected with in any manner (including but not limited to acting as an
employee or independent contractor), any business, person, firm, or
corporation, which (i) provides or intends to provide the same services as the
Company or is otherwise competitive with the Company's products or services;
or (ii) is engaged in or intends to engage in any line(s) of business that
would be competitive with any other lines of business that the Company has
made a decision to engage in prior to the termination of Employee's employment
with the Company. This covenant is made to protect the Company's proprietary
and confidential information. In addition, the covenant is made
contemporaneously with and as independent consideration for, the execution of
the Agreement of Limited Partnership of Rackspace, Ltd. of which Employee is a
limited partner. Due to the nature of the Company's business (which involves
internet products and services), it is not practical to impose a geographical
limitation on the prohibitions contained herein. At the end of the Employee's
employment, the Company shall provide the Employee with a written list of the
business activities which the Company is engaged in or which the Company has
made a decision to become engaged in.

     If any covenant contained in this Section 6(b), or any part thereof, is
hereafter construed to be invalid or unenforceable, the same shall not affect
the remainder of the covenant or covenants, which shall be given full effect,
without regard to the invalid portion or portions. If any covenant in this
Section 6(b), or any part thereof, is held to be unenforceable because of its
duration or its geographic scope, the parties agree that the court making such
determination shall have the power to reduce the duration and/or area of such
covenant to the longest duration and to the greatest geographical scope which
is permitted, and, in said reduced form, such covenant shall then be enforced.

     7.   REMEDIES FOR BREACH. Notwithstanding the provisions of Section 10
hereof, if Employee breaches, or threatens to breach, any of the provisions of
Section 6 hereof, the Company shall have the following rights and remedies,
in addition to any others, each of which shall be independent of the other and
severally enforceable:

<PAGE>

          (i) The right to have the provisions of Section 6 of this Agreement
specifically enforced by any court having equity jurisdiction, it being
acknowledged and agreed that any such breach or threatened breach will cause
irreparable injury to the Company and that monetary damages will not provide
an adequate remedy to the Company;

          (ii) The right to obtain an injunction to prevent the Employee from
taking actions prohibited by this Agreement without the requirement of posting
a bond, it being acknowledged and agreed that any such breach or threatened
breach will cause irreparable injury to the Company and that monetary damages
will not provide an adequate remedy to the Company;

          (iii) The right and remedy to require Employee to pay all damages
resulting from such breach; and

          (iv) The right to terminate Employee's employment for "Cause"

period.

          (b)  TERMINATION FOR CAUSE. The Company may terminate Employee's

his duties, or (ii) the engaging by Employee in conduct that is materially and
demonstrably injurious to the Company, monetarily or otherwise, which shall be
deemed to include violating any material term of this Agreement.

notice to Employee of the specific action proposed to be taken and the grounds
therefor and a reasonable opportunity for Employee to respond thereto to the
Company and to cure such situation.

terminate Employee's employment at any time without Cause by giving at least
thirty (30) days prior written notice to Employee of the Company's election to

employment at the end of the four year initial term (whether with or without
cause) or any time after the four year initial term, Employee shall only be
entitled to his salary and benefits through the date of termination and no
more. If the Company terminates the Employee's employment without Cause during
the initial four year Term or in the event that Employee's employment is
terminated due to Disability during the initial four year Term, and the

<PAGE>

     4.   COMPENSATION.

          (a)  BASE COMPENSATION. During the Term, the Company shall pay to

Company's business, or are created with the use of the facilities or materials
of the Company.

     6.   CONFIDENTIALITY AND COMPETITIVE ACTIVITIES.

          (a)  CONFIDENTIALITY. In view of the fact that Employee's work with
the Company will bring him into close contact with many confidential affairs of
the Company, including matters of a business nature such as information about
costs, profits, markets, sales, trade secrets, potential patents and other
business ideas, customer lists, plans for future developments, business
opportunities, and information of any other kind not known within any industry
in which the Company operates (hereinafter, collectively, "Confidential
Matters"), Employee agrees:

          (i)  To keep secret all Confidential Matters of the Company and of any
subsidiaries and affiliates of the Company and not to disclose them to anyone
outside of the Company or its subsidiaries or affiliates, or otherwise use them
or use his knowledge of them for his own benefit, including, without limitation,
use of the trade names or trademarks of the Company, either during or after the
Term, except with the Company's prior written consent; and

<PAGE>

          (ii) To deliver promptly to the Company at the termination of the
Term, or at any time the Company may request, all memoranda, notices, records,
reports and other documents (and all copies thereof) relating to the business of
the Company or any of its subsidiaries or affiliates, including, but not limited
to, Confidential Matters, which he may then possess or have under his control.

     Notwithstanding any of the foregoing, the term "Confidential Matters" does
not include information which (i) Employee is compelled to disclose by judicial
or administrative process, or in the opinion of his counsel, by other mandatory
requirements of law, or (ii) is or becomes generally available to the public
other than as a result of any disclosure by Employee.

     (b)  COMPETITIVE ACTIVITIES. During Employee's employment and for a
period of(i) six (6) months following the effective date of a termination of
Employee's employment "without cause", or as a result of his disability, (ii)
eighteen (18) months following the effective date of a termination of
Employee's employment in the event Employee resigns or is terminated for
Cause, Employee shall not, directly or indirectly, or through any subsidiary
or affiliate, own, consult, advise, manage, operate, join, or control, or
participate in the ownership, management, operation, or control of, or be
connected with in any manner (including but not limited to acting as an
employee or independent contractor), any business, person, firm, or
corporation, which (i) provides or intends to provide the same services as the
Company or is otherwise competitive with the Company's products or services;
or (ii) is engaged in or intends to engage in any line(s) of business that
would be competitive with any other lines of business that the Company has
made a decision to engage in prior to the termination of Employee's employment
with the Company. This covenant is made to protect the Company's proprietary
and confidential information. In addition, the covenant is made
contemporaneously with and as independent consideration for, the execution of
the Agreement of Limited Partnership of Rackspace, Ltd. of which Employee is a
limited partner. Due to the nature of the Company's business (which involves
internet products and services), it is not practical to impose a geographical
limitation on the prohibitions contained herein. At the end of the Employee's
employment, the Company shall provide the Employee with a written list of the
business activities which the Company is engaged in or which the Company has
made a decision to become engaged in.

     If any covenant contained in this Section 6(b), or any part thereof; is
hereafter construed to be invalid or unenforceable, the same shall not affect
the remainder of the covenant or covenants, which shall be given full effect,
without regard to the invalid portion or portions. If any covenant in this
Section 6(b), or any part thereof, is held to be unenforceable because of its
duration or its geographic scope, the parties agree that the court making such
determination shall have the power to reduce the duration and/or area of such
covenant to the longest duration and to the greatest geographical scope which is
permitted, and, in said reduced form, such covenant shall then be enforced.

     7.   REMEDIES FOR BREACH. Notwithstanding the provisions of Section 10
hereof, if Employee breaches, or threatens to breach, any of the provisions of
Section 6 hereof, the Company shall have the following rights and remedies, in
addition to any others, each of which shall be independent of the other and
severally enforceable:

taking actions prohibited by this Agreement without the requirement of posting a
bond, it being acknowledged and agreed that any such breach or threatened breach

provide an adequate remedy to the Company;

          (iii) The right and remedy to require Employee to pay all damages
resulting from such breach; and

          (iv)  The right to terminate Employee's employment for "Cause"

then that controversy or claim will be mediated within one month of its
identification by the parties.
