     Each Partner agrees to cooperate with the tax matters partner and to do
or refrain from doing any or all things reasonably required by said Partner to
conduct such proceedings. In the event that said Partner, while acting as the
"tax matters partner," ceases to be the General Partner for any reason, the
remaining Partners shall immediately elect a substitute tax matters partner
who shall be the "tax matters partner" of the Partnership.

     SECTION 3.9    BANK ACCOUNTS. The General Partner shall establish one or
more bank accounts in the name of the Partnership into which all funds of the
Partnership shall be deposited. No other funds shall be deposited or commingled
in these accounts. Partnership funds may be withdrawn from the accounts upon the
signature of the General Partner, or its designee, for the purpose of paying the
debts of the Partnership, reimbursing the General Partner for expenses incurred
pursuant to Section 3.11, distributing Cash Available for Distribution to the
Partners, or any other purpose authorized under this Agreement.

     SECTION 3.10   BOOKS AND RECORDS. The General Partner, on behalf of the
Partnership, shall keep and maintain at the principal office of the
Partnership the following records:

          a.   List of Partners. A current list that states the name and
mailing address of each Partner, the Ownership Percentage Interest in the
Partnership owned by each Partner; the number of Units owned by Limited Partner

          b.   Tax Returns. Copies of the Partnership's federal, state, and
local information or income tax returns for each of the Partnership's six most
recent tax years.

          c.   Agreement. A copy of this Agreement and the Certificate of
Limited Partnership; copies of any restatements of this Agreement; and
executed copies of any powers of attorney under which this Agreement, the
Certificate of Limited Partnership, and all amendments or restatements thereto
have been executed.

          d.   Books. Correct and complete books and records of account of the
Partnership.

Each of the Partners agree to furnish the General Partner all documents
regarding costs and expenses and other financial information which are
necessary to maintain such records. Any Partner (or their duly authorized
representatives), on written request to the General Partner, stating the
purpose, may examine and copy, at any reasonable time, for any proper purpose,
and at the Partner's expense, these records and other information kept by the
General Partner on behalf of the Partnership. However, under no circumstances
shall the Partnership or the General Partner have the obligation to provide
information regarding the Partnership to any Limited Partner, except to the
extent that such information is requested for a proper purpose and the General
Partner determines that the disclosure of such information will not harm the
Partnership. The above notwithstanding, if a Class A Limited Partner is no
longer employed by the Partnership, then he (and any transferee or assignee of
such Class A Limited Partner) shall lose his rights to review the books of the
Partnership, to receive any reports from the Partnership and any other right
of a Limited Partner other than the right to receive the distributions and
allocations from the Partnership at such times as those distributions and
allocations may be made by the Partnership. However, at the Class A Limited
Partner's sole cost and expense, at the request of such Class A Limited
Partner, the Partnership shall have the books and records of the Partnership
audited to determine whether or not the Partnership has properly made
distributions and allocations to such Class A Limited Partner. If the audit

                                     12

<PAGE>

determines that such distributions and allocations have been improperly made,
and such discrepancy is at least a 5% difference between the proper allocation
or distribution, and the allocation or distribution made by the General
Partner, then the Partnership shall pay the cost of the audit.

     SECTION 3.11   REIMBURSEMENT OF GENERAL PARTNER. The General Partner is
entitled to be reimbursed for reasonable out-of-pocket costs and expenses
incurred by the General Partner on behalf of the Partnership; provided that if
any costs and expenses are incurred to reimburse any Related Party of the
General Partner, Miller, Weston or Trout, the transaction giving rise to such
reimbursement shall have been made on terms no less favorable to the
Partnership than could be reasonably expected to be obtained from a third
party. Without the approval of the Class A Limited Partners, the General
Partner will not be reimbursed for any of its overhead costs and expenses.

                                      ARTICLE 4.

     RIGHTS, PROHIBITIONS, AND LIABILITIES OF LIMITED PARTNERS

     SECTION 4.1    RIGHTS OF LIMITED PARTNERS. The Limited Partners shall be
entitled to the rights provided by the Act, as the same may be lawfully
modified by the terms of this Agreement.

     SECTION 4.2    PROHIBITIONS WITH RESPECT TO LIMITED PARTNERS. The Limited
Partners shall not have the right to:

          a.   Participate in the control of the business affairs of the
Partnership except as expressly provided herein; transact any business on
behalf of or in the name of the Partnership; or have any power or authority to
bind or obligate the Partnership;

          b.   Have their original investments, if any, repaid (i) until the
Partnership is dissolved, all Partnership liabilities have been paid or funds
have been set aside therefor, and compliance with the provisions for
dissolution hereunder cause such repayment, or (ii) unless the terms of the
Act, as the same may be lawfully modified by the terms of this Agreement, are
complied with and the same require such repayment, except that distributions
authorized by Section 7.2 hereof shall be made from time to time and may in
some cases represent a return of a Limited Partners' original investment; or

          c.   Sell or assign any of such Limited Partner's interest in the
Partnership, except as expressly provided herein.

     SECTION 4.3    LIABILITIES OF LIMITED PARTNERS. A Limited Partner shall
not be personally liable for any amounts other than the amounts subscribed by
such Limited Partner to the capital of the Partnership, and shall not be
liable for any debts, obligations or losses of the Partnership or of the
General Partner.

<PAGE>

     SECTION 4.4    DEFICIT CAPITAL ACCOUNTS. The Limited Partners shall not
be obligated to restore the amount of any deficit balance in their respective
Capital Accounts, as such term is hereinafter defined, upon the liquidation of
their interest in the Partnership or upon the liquidation of the Partnership
itself.

     SECTION 4.5    LOANS TO THE PARTNERSHIP. Trout agrees to cause the
Partnership to be lent up to $1,050,000.00, $550,000.00 of which is
non-discretionary as further described below and $500,000.00 of which shall
be to fund positive circumstances; provided that Trout, in its sole
discretion determines that such $500,000.00 is needed by the Partnership and
that such loan can be prudently made by the lender. Such loan or loans will
bear interest at the annual rate of 8% interest compounded annually. No
payments of principle or interest will be due for the first three years from
the date funds are first advanced. Beginning in the fourth year monthly
payments of principal and interest will be due and payable based upon an
amortization of the principle and accrued interest (as of the end of the
third year) over the following five years. Such loan or loans will be fully
secured by the assets of the Partnership. The loan or loans may be prepaid at
anytime by the Partnership without penalty. Upon the execution of this
Agreement, not less than $150,000.00 will be advanced to the Partnership by
Exeter Financial, LC pursuant to this Section 4.5. Within six months of the
execution of this Agreement, Trout will cause Exeter Financial LC to advance
an additional advance of $400,000.00 to the Partnership. These two initial
advances shall not be subject to Trout's discretion. Any guaranty by Trout of
the Partnership's debts and obligations shall be treated as an advance under
this paragraph, provided that no interest shall be paid to Trout in respect
of the guaranteed amount unless Trout is forced to pay on the guaranty.

     SECTION 4.6    LIFE INSURANCE. The Partnership will purchase a key-man
policy in the amount of $1,250,000 for Yoo. The policy shall be structured to
require, that upon the death of Yoo, Trout is paid $200,000 of the proceeds,
the Partnership's lender (as referenced in Section 4.5) receives the remaining
proceeds up to the amount owing under its loan to the Partnership (and such
amount will fully discharge such loan as well as any obligation of Trout to
cause additional funds to be loaned to the Partnership pursuant to Section 4.5
above), and any remainder is paid to the Partnership.

     SECTION 4.7    LOCATION FOR SERVERS. Trout agrees to use its reasonable
best efforts to secure a location for the Partnership's data center and
offices at favorable rent.

                                      ARTICLE 5.

General Partner to Additional Limited Partners in accordance with the terms of
this Agreement. In the event Additional Limited Partners are admitted to the
Partnership in accordance with the terms of this Agreement, the Ownership
Percentage Interests of each Partner shall be adjusted pro rata, and the
Ownership Percentage Interests of such Additional Limited Partner(s) shall be
established by the General Partner, as provided herein. The General Partner's
rights hereunder are not intended to reduce the General Partner's fiduciary
duty to the Limited Partners.

     SECTION 5.2    CAPITAL CONTRIBUTIONS.

capital to the Partnership except as otherwise provided in this Agreement.

or to receive any distribution from the Partnership, except as specifically
provided herein.

                         ALLOCATIONS OF INCOME, GAIN AND LOSS

     SECTION 6.1    ALLOCATION OF PARTNERSHIP NET INCOME AND GAIN. All
Partnership net income and gain for each tax year of the Partnership will be
allocated as follows:

FIRST:    LOSS RECAPTURE ALLOCATION. To the Limited Partners in an amount equal
          to the cumulated amount of any Specially Allocated Losses.

SECOND:   REGULAR ALLOCATION. The remainder, to all the Partners in accordance
          with their Ownership Percentage Interests in the Partnership.

     SECTION 6.2    ALLOCATION OF PARTNERSHIP LOSSES. All Partnership losses
shall be allocated among the Partners in accordance with their Ownership
Percentage Interests in the Partnership until the Capital Accounts of all
Limited Partners other than Trout, are reduced to zero (the "Regular Loss
Allocation"). To the extent that the Capital Account balances of all the
Limited Partners other than Trout are zero, any additional losses (the
"Specially Allocated Losses") will be allocated to Trout (and its assigns).

     SECTION 6.3    SPECIAL TAX ALLOCATIONS. Notwithstanding anything to the
contrary in this Agreement, the Partnership shall make the following tax
allocations if so required by the Code or Regulations:

          SECTION 704(C) PROVISIONS. Upon the sale of the Partnership property
          contributed by a Partner (or any property received in exchange for
          such property), the resulting gain or loss shall be allocated to that
          Partner and/or to any transferee of any interest in the Partnership
          from such Partner for income tax purposes as provided in Section
          704(c) of the Code and applicable Regulations.

          QUALIFIED INCOME OFFSET. Any Partner who unexpectedly receives an
          adjustment, allocation, or distribution described in subparagraphs
          (4), (5) or (6) of Treas. Reg. Section 1.704-1(b)(2)(ii)(d), which
          adjustment, allocation or distribution creates or increases a deficit
          balance in that Partner's Capital Account, shall be allocated items
          of book income and gain in an amount and manner sufficient to
          eliminate the deficit balance in that Partner's Capital Account so
          created or increased as quickly as possible in accordance with
          Treas. Reg. Section 1.704-1(b) (2)(ii)(d) and its requirements for
          a "qualified income offset."

          MINIMUM GAIN CHARGEBACK. If Regulations relating to Section 704(b) of
          the Code require a Minimum Gain Chargeback to cause the allocations
          under Section 3.1 of this Agreement to have substantial economic
          effect, the tax

                                     16

<PAGE>

          allocations described in Section 3.1 shall be adjusted to accommodate
          the necessary Minimum Gain Chargeback.

                                      ARTICLE 7.

                                    DISTRIBUTIONS

     SECTION 7.1    GENERAL. The General Partner shall cause the Partnership
to distribute cash for Tax Distributions to the Partners on an annual basis.
However, to the extent the Partnership incurs losses, no Tax Distributions
will be made until the cumulated net income and gain of the Partnership
exceeds the cumulated amount of such losses. Otherwise, the Partnership will
only distribute cash to the extent that the General Partner determines that
such cash is not needed for Partnership operations and expansion, working
capital and contingencies ("Cash Available for Distribution").

     SECTION 7.2    DISTRIBUTION OF CASH AVAILABLE FOR DISTRIBUTION. To the
extent that Tax Distributions or distributions of Cash Available for
Distribution are made by the Partnership, such distributions shall be made as
follows:

FIRST:    TAX DISTRIBUTIONS. Tax Distributions shall be made to the Partners in
          an amount equal to the amount of any federal income tax estimated by
          the General Partner to be incurred by the Partners (such estimate to
          be made on the assumption that all of the Partners will be taxed at
          the highest marginal tax rate applicable to individuals, which is
          currently 39.59%) on their allocable share of any net income or gain
          from the Partnership which is recognized for federal income tax
          purposes during the prior year and not otherwise distributed to the
          Partners. However, to the extent the Partnership incurs losses, no
          Tax Distributions will be made until the cumulated net income and
          gain of the Partnership exceeds the cumulated amount of such losses.
          Tax Distributions shall be made not later than February 28th of each
          year.

SECOND:   REGULAR DISTRIBUTIONS. Regular Distributions of the remaining Cash
          Available for Distribution shall be made to all the Partners in
          accordance with their Capital Accounts.

                                      ARTICLE 8.

                                 DISPOSITION OF UNITS

     SECTION 8.1    REPURCHASE OF CLASS A LIMITED PARTNERS' UNITS BY
PARTNERSHIP. As set forth below and subject to the limitations set forth
herein, the Partnership will have the right to purchase all or a portion (as
described in more detail below) of Condon and

                                     17

<PAGE>

Elmendorf's Units (and they shall have the obligation to sell such Units) in
the event that either of them are no longer employed by the Partnership,
whether as a result of death, resignation, termination for cause, termination
without cause, disability or otherwise; provided that the triggering event
(end of employment) occurs prior to the end of the four year employment term
(as set forth in the employment agreement between each of Condon and Elmendorf
and the Partnership (the "Employment Agreements")). Notwithstanding the
foregoing, the Partnership will not have the right to purchase Elmendorf's and
Condon's Units under this Section 8.1 if the termination of their employment
occurs on or after January 1, 2003. To the extent that: (i) the right to
purchase arises prior to January 1, 2001 and arises out of the resignation or
termination for "cause" (as defined in the Employment Agreements), the
purchase price for Condon or Elmendorf's Units will be the book value of the
Units, (ii) the right to purchase arises at any time and arises out of the
termination of employment without "cause" (as defined in the Employment
Agreements) the purchase price will be the greater of the fair market value
(with no minority ownership or control discount applied) for the Units being
sold (determined by an independent appraiser, who is either (a) selected by
the mutual agreement of the Partner whose Units are being repurchased and the
Partnership, (b) a "big six" accounting firm selected by the Partnership
(provided such accounting firm is not utilized by the Partnership, the General
Partner, Weston or Miller or any Related Party of the foregoing), or, (c) a
third party independent appraiser designated by a "big six" accounting firm
selected by the Partnership (provided such accounting firm is not utilized by
the Partnership, the General Partner, Weston or Miller or any Related Party of
the foregoing)), or the amount of the respective annual salaries of Elmendorf
or Condon, as to Units sold by each of them, respectively, (iii) the right to
purchase arises under any other event, the purchase price will be the fair
market value for the Units being sold (with no minority ownership or control
discount applied), as determined by an independent appraiser selected in
accordance with the provision set forth above. Payment for the Units shall be
20% in cash and the remainder paid pursuant to a promissory note bearing
interest at the rate of 8%, fully amortized over four years. However, in the
event that the purchase arises out of the termination without "cause", 30%
will be paid in cash and the balance will be paid over three years on the
other terms described in the preceding sentence. The Partnership's right to
purchase all of Condon's and Elmendorf's Units in the event that their
employment ends prior to January 1, 2003 is limited by the following: (A) If
(i) Condon or Elmendorf, as the case may be, provides the Partnership with 45
days prior written notice of his election to resign and such resignation takes
place on or after January 1, 2001, or (ii) prior to January 1, 2001, Condon or
Elmendorf dies, becomes disabled, or is terminated by the Partnership without
cause, Elmendorf or Condon, as the case may be, may elect to retain up to
fifty percent (50%)of his Units, (B) To the extent that the termination of
employment occurs after January 1, 2001, Condon or Elmendorf, as the case may
be, may elect to retain that percentage of his Units which is determined by
dividing the number of months that Condon or Elmendorf, as the case may be, is
employed by the Partnership from January 1,1999, by 48. The Partnership shall
have the exact same rights with respect to Yoo and Yoo shall have the exact
same obligations as set forth above, except that if prior to January 1, 2002,
Yoo is terminated for "cause" (as defined in the Employment Agreement between
the Partnership and Yoo) or Yoo resigns prior to January 1, 2002 (or Yoo
otherwise resigns at anytime without giving 45 days prior written notice), the
Partnership will have the right to purchase

                                     18

<PAGE>

all of his Units at book value, and if Yoo is terminated without "cause" (as
defined in the Employment Agreement), the purchase price for his Units will be
the greater of the fair market value (as determined by an independent
appraiser selected in the method described above and with no minority
ownership or control discount applied) of his Units being sold or an amount
equal to 1.5 multiplied by Yoo's annual salary in effect immediately prior to
then end of his employment. With respect to Condon and Elmendorf, the
Partnership, to the extent it desires to exercise its right to purchase their
Units, must purchase all of the Units which are subject to the right of
purchase. With respect to Yoo, the Partnership, to the extent that it desires
to exercise its right to purchase his Units, may purchase less than all of the
Units which are subject to the right of purchase. However, the Partnership may
not elect to leave Yoo with a de minimis number of Units. The book value and
fair market value of Units subject to sale to the Partnership, shall be
determined as of the end of the last fiscal quarter of the Partnership
immediately prior to the end of employment, provided that the appraiser shall
be entitled to take into consideration any events occurring after the last
fiscal quarter which may have a material effect on the fair market value of
the Units, including the departure of any key employee.  The above
notwithstanding, in the event of a merger or other business combination, sale
of all or substantially all of the Partnership's assets or in the event that
the Partnership (or a successor entity created for the purpose of making a
public offering) completes a public offering underwritten by a nationally
recognized underwriter and raises more than $10,000,000.00 for the Partnership
(or the successor entity), all the rights of the Partnership to repurchase the
Yoo's Elmendorf's and Condon's Units shall automatically terminate. In order
to clarify the rights of the Partnership described in this Section 8.1,
Exhibit B is attached hereto to outline the rights and obligations of the
parties.

     SECTION 8.2    PROHIBITED DISPOSITIONS. Elmendorf, Yoo and Condon
(collectively, the "Class A Partners") shall not make any sale, transfer,
pledge, assignment or other disposition of any of their Units which may be
purchased by the Partnership pursuant to the Partnership's rights under
Section 8.1 above.  Therefore, as to each Class A Limited Partner, for so long
as the Partnership has the right to acquire any of such Class A Partners'
Units in the event that he is no longer employed by the Partnership, no
disposition of those Units which may be acquired by the Partnership may be
made by such Class A Partner. In any circumstances where the prior two
sentences do not restrict the transfer of the Units owned by the Class A
Partners, no Limited Partner (including any assignee of a Limited Partner)
other than Trout may propose to make any sale, transfer, pledge, assignment or
other disposition of all or any part of their Units or other Limited
Partnership interests (such interests referred to as the "Units Offered for
Sale") except in exchange for cash or a combination of cash and promissory
notes. Prior to making such disposition, the Class A Limited Partner (the
"Selling Partner") shall first offer his or her Units Offered for Sale to
Trout under the same terms and conditions as the proposed sale (the "Terms of
Sale"). Such offer shall be in writing and delivered to Trout, along with the
name of the proposed purchaser of the Units Offered for Sale. The Selling
Partner shall provide to Trout all information regarding the proposed sale and
the proposed purchaser, as may be reasonably requested by Trout. Trout shall
have four business (4) days from the receipt of such written offer to (i)
elect in writing to purchase all of such Units Offered for Sale, and (ii) make
available to the Selling Partner at the offices of the General Partner, an
amount equal to ten

                                     19

<PAGE>

(10%) percent of the purchase price of the Units Offered for Sale as a
non-refundable deposit. Payment for the Units Offered for Sale shall be made
in accordance with the Terms of Sale. If Trout does not elect to purchase all
the Units Offered for Sale, the Selling Partner shall be free to sell all, but
not less than all of such Units Offered for Sale for a period of sixty (60)
days after the expiration of the Trout's option, provided that any such sale
must be made under the same terms and conditions as the Terms of Sale and to
the proposed purchaser named in the Terms of Sale. The Selling Partner shall
provide all information relating to the transferee of the Units Offered for
Sale which is reasonably requested by the General Partner. Trout and Macroweb
may not propose to make any sale, transfer (which shall include a merger,
statutory exchange, consolidation of either Trout or Macroweb), pledge,
assignment or other disposition of all or any part of their Units or other
interests in the Partnership (such interests desired to be sold, transferred,
pledged or assigned are referred to as the "Controlling Units offered for
Sale") except by sale of cash or a combination of cash and promissory notes.
Prior to making such disposition, Trout or Macroweb, as the case may be, shall
first offer the Controlling Units Offered for Sale to the Class A Limited
Partners, in proportion to their Ownership Interests in the Partnership under
the same terms and conditions as the proposed sale (the "Terms of Sale").
Trout and/or Macroweb shall provide to the Class A Limited Partners all
available information regarding the proposed sale and the proposed purchaser,
as may be reasonably requested by the Class A Limited Partners.  The Class A
Limited Partners shall have four (4) business days from the receipt of such
written offer to (i) elect in writing to purchase all of the Controlling Units
Offered for Sale (in proportion to their Ownership Interests in the
Partnership, or in whatever other proportion they may otherwise agree), and
(ii) make available to Trout and Macroweb at the offices of the General
Partner, an amount equal to ten (10%) percent of the purchase price of the
Controlling Units Offered for Sale as a non-refundable deposit; provided that,
in lieu of such deposit, the Class A Limited Partners may pledge (under a
pledge agreement acceptable to Trout or Macroweb, as the case may be) their
Units as security for their obligation to pay an amount equal to 10% of the
purchase price of the Controlling Units Offered for Sale as a non-refundable
deposit. Payment for the Controlling Units Offered for Sale shall be made in
accordance with the Terms of Sale. In addition, to the extent that the Terms
of Sale require a note or notes, the Class A Limited Partners, to the extent
they desire to purchase all of the Controlling Units Offered for Sale, shall
be required to demonstrate that they have at least the same credit worthiness
as the proposed purchaser. If the Class A Limited Partners do not elect to
purchase all of the Controlling Units Offered for Sale or cannot demonstrate
the same credit worthiness as the proposed purchaser under Terms of Sale which
include a note or notes, Trout and/or Macroweb, as the case may be, shall be
free to sell all the Controlling Units Offered for Sale for a period of sixty
(60) days after the expiration of the Class A Limited Partners' option,
provided that any such sale must be made under the same terms and conditions
as the Terms of Sale.  Trout shall provide all information relating to the
transferee of the Controlling Units Offered for Sale which is reasonably
requested by the General Partner. Except as specifically allowed under this
Agreement, no Limited Partner may sell, assign, transfer, mortgage, encumber,
hypothecate, pledge or otherwise dispose of all or any part of such Limited
Partner's interests in the Partnership and any attempt to take such action and
any purported separate sale, transfer, assignment, mortgage, encumbrance,
hypothecation, pledge, or other disposition by any Limited Partner shall be
void. In the event of any sale, transfer,

                                     20

<PAGE>

assignment or other disposition which is not made in accordance with this
Agreement, and without herein recognizing such as being permitted or valid,
the Limited Partner making the same shall remain and continue to be liable for
the performance of all of its obligations hereunder and the Partnership shall
continue to make any distributions, if any, to said Limited Partner. All
subsequent owners of any Units, or other Limited Partnership interests
hereunder shall hold same subject to all the terms and provisions hereof. To
the extent that the provisions of this Section 8.2 and the other provisions of
this Agreement are followed incident to any sale of Units, the transferee of
such Units shall become a Substitute Limited Partner of the Partnership with
the written consent of the General Partner, which consent shall not be
withheld or delayed. With respect to any transfer of all of the Units and
interests in the Partnership held by Macroweb, the transferee shall become the
substitute General Partner of the Partnership, provided that the provisions of
this Section 8.2 and all other provisions of this Agreement are followed
incident to the sale of such Units and interests.

     SECTION 8.3    TRANSFERS TO A FAMILY MEMBER. Any Limited Partner shall be
permitted to transfer his or her Units or other Limited Partnership interests
to a Family Member or a trust established for the benefit of a Family Member
("Trust") without subjecting such Units to the right of first refusal contained
in Section 8.2 above, provided that written notice of such transfer is
provided to the General Partner at least thirty (30) days prior to the
transfer. However, no such Family Member or Trust shall become a Substitute
Limited Partner without the express written consent of the General Partner and
the Approval of the Class A Limited Partners, which consent may be arbitrarily
withheld. It is expressly agreed that Trout may transfer its Units to Miller,
Weston or any of their Family Members or a trust established for the benefit
of a Family Member.

     SECTION 8.4    TRANSFER OF UNITS. Each Partner affirms that he/she/it has
purchased and now holds his, her or its Units for his, her or its own account,
solely for investment and not with any intention of distributing, dividing, or
reselling the same. In addition to other restrictions on transfer contained in
this Agreement, the Units and any other Limited Partnership interests may be
assigned, pledged, or subjected to a security interest (collectively referred
to as "disposition") only if:

          a.   Such disposition is consistent with such affirmation;

          b.   The transferee of such disposition is not a competitor of the
Partnership;

          c.   Except with respect to a transfer to a Family Member or a trust
established for the benefit of a Family Member, such Partner has first offered
to sell the Units or other Limited Partnership interests in accordance with
Section 8.2 above; and

          d.   The following conditions to such disposition have been met,
unless such conditions have been waived in writing by the General Partner in its
sole discretion which discretion, may be arbitrarily exercised:

                                     21

<PAGE>

               (i)  the transferee has delivered an instrument reasonably
          satisfactory to the General Partner which accepts and adopts the
          terms and provisions of this Agreement, including the assumption of
          all obligations of the transferor to the Partnership and an
          agreement to be subject to all transfer restrictions applicable to
          his/her or its transferor;

               (ii) the transferor has delivered to the General Partner an
          opinion of counsel, who is reasonably satisfactory to the General
          Partner, in form and substance satisfactory to counsel designated by
          the General Partner to the effect that the tax status of the
          Partnership will not be adversely affected by the transfer;

               (iii) the transferor has delivered to the General Partner an
          opinion of counsel, who is reasonably satisfactory to the General
          Partner, in form and substance satisfactory to counsel designated by
          the General Partner to the effect that neither the assignment nor any
          offering in connection therewith violates any provision of any
          federal or state securities or comparable law;

               (iv) the General Partner has determined that the transfer would
          not cause a termination of the Partnership within the meaning of
          Section 708(b) of the Code; and

               (v)  the transferor pays for all expenses incurred by the
          Partnership in connection with such disposition.

     It is further expressly provided herein that the Partners shall not make
any transfer, assignment, lease, or gift of any interest in the Partnership to
a "tax exempt entity" as that term is defined in the Code which would cause
such tax exempt entity to become directly or indirectly a Partner in the
Partnership. Any such transfer to such a tax exempt entity shall be void.

     SECTION 8.5    PARALLEL EXIT. No Partner (including any transferee or
assignee)or any Family Member or trust established for the benefit of a Family
Member which has received Units from a Partner (a "Transferee"), may sell any
of their Units without first offering to all of the Limited Partners
(including any Additional Limited Partners), the right to participate in such
transfer, on a pro rata basis, on the same terms and conditions as the
proposed sale by the Partner or Transferee seeking to transfer Units. Before
making any sale the Partner or any Transferee shall provide each of the other
Limited Partners and any Additional Limited Partners with written notice of
the date and terms of the proposed sale and each of the other Limited Partners
and the Additional Limited Partners shall each have the right to sell his or
her Units or other Limited Partnership interests pursuant to such sale in an
amount equal to the Units subject to purchase, multiplied by a fraction, the
numerator of which shall be the Ownership Percentage Interests held by such
Limited Partner or Additional Limited Partner, as the case may be, and the
denominator of which is the total amount of the Ownership Percentage Interests
held by all the Partners electing to participate in such sale.  Any Limited

                                     22

<PAGE>

Partner or Additional Limited Partner who elects to participate in such sale,
shall be required to irrevocably make its election within four business days
of receipt of written notice from the Limited Partner or Transferee.
Notwithstanding the foregoing, any purchase of less than all of the Units
elected to be sold as provided above, shall be made from all parties
participating in the sale, pro rata, based on the number of Units to be sold
by each. The provisions of this Section 8.5 will not apply to any involuntary
sale of Units, such as a sale under the terms of a pledge or security
agreement, nor does this provision apply to any transfer to a Family Member
of a Limited Partner or a trust established for the benefit of a Family
Member of a Limited Partner.

     SECTION 8.6    STATUS OF TRANSFEREE. The transfer by a Limited Partner of
his/her or its Units, or other Limited Partnership interests shall not
constitute the person acquiring such Units, or other Limited Partnership
interests, to become a Substitute Limited Partner, except with the express
written consent of the General Partner. Such consent may not be withheld if
all of the requirements for transfer which are set forth herein have been met.
No such substitution shall become effective until such transferee and all of
the Partners, (either individually or through their agent or attorney in fact,
including the General Partner as such attorney-in-fact) execute all
amendments, certificates and other documents and perform all acts relating to
such substitution which the General Partner deems appropriate to comply with
applicable requirements of law so as to preserve the limited liability status
of the Partnership upon the completion of such substitution under the laws of
the jurisdictions in which the Partnership is doing business. Without in any
way limiting the power of attorney contained in Article 12, each Partner
agrees upon request of the General Partner to execute such amendments,
certificates or other documents and perform such acts.

     SECTION 8.7    EFFECTIVE TIME OF TRANSFER. A purported transfer of a
Unit(s), or any other Limited Partnership interest shall be valid as to the
Partnership and the General Partner on the first day of the month following
the month in which the foregoing conditions have been met (whereupon the
General Partner shall cause the name of the transferee to be registered as the
holder of such Unit or Units upon the records maintained for that purpose as
provided in Section 3.12).

     SECTION 8.8    SUBDIVIDED UNITS PROHIBITED. Without the written consent
of the General Partner, which may be arbitrarily withheld, Limited Partners
shall not be permitted to sell, transfer, assign, convey, give, donate or
bequeath a fractional part of a Unit, or other fractional part of a Limited
Partnership interest, except to the extent such fractional part was issued as
such upon the formation of the Partnership.

     SECTION 8.9    TRANSFER TO BELL AND GRUBBS. Notwithstanding anything
herein to the contrary, Yoo is specifically authorized to transfer and assign
5000 Units to Brian Bell and 5000 Units to Edwin Grubbs, and Yoo agrees to
make such assignment as soon as practicable after the execution of this
Agreement. The General Partner specifically consents to such alignment and
such assignment shall not be subject to the rights of first refusal contained
in Section 8.2; however, the parties shall be required to comply with the
requirements of Section 8.3. Brian Bell and Edwin Grubbs shall be assignees
only and shall not become Substitute

                                     23

Limited Partners.

                                      ARTICLE 9.

                             ADDITIONAL LIMITED PARTNERS

     SECTION 9.1    ADMISSION OF NEW PARTNERS. In order to raise additional
capital for the Partnership, the General Partner is authorized to admit
Additional Limited Partners and to sell additional Units and other Limited
Partnership interests in the Partnership, under such terms and conditions as
may be negotiated by the General Partner in an arms-length transaction
consistent with the General Partner's fiduciary duty to the Partnership.
However, unless and until at least $1,050,000 has been loaned to the
Partnership pursuant to Trout's obligations under Section 4.5 above (i)
neither Trout, Macroweb, Miller, Weston or any of their Related Parties may be
sold additional Units and other Limited Partnership interests in the
Partnership, and (ii) no sale of the Partnership's Units will be made without
the Approval of the Class A Limited Partners.  Incident to admitting
Additional Limited Partners and notwithstanding anything in this Agreement to
the contrary, the terms of this Agreement may be amended by the General
Partner without the consent of the Limited Partners in order to provide for
the rights and duties of such Additional Limited Partners. In the event
Additional Limited Partners are admitted to the Partnership by the General
Partner, the Ownership Percentage Interests of each existing Partner shall be
adjusted on a pro rata basis and the Ownership Percentage Interests of such
Additional Limited Partner shall be established by the General Partner.

     SECTION 9.2    PREEMPTIVE RIGHTS. To the extent that the General Partner
proposes to sell additional Units or other Limited Partnership interests or
securities exercisable for or convertible into such Units or other Limited
Partnership Interests as permitted in Section 9.1 above for cash, the General
Partner shall first offer such Limited Partnership interests to all the
Partners and each Partner shall be entitled to purchase an amount of such
Limited Partnership interests in proportion to the Ownership Percentage
Interest of each Partner. Upon receipt of the offer, to the extent that any of
the Limited Partners desire to accept the offer they must, within four
business days of receipt of the offer, (i) notify the General Partner in
writing of acceptance, and (ii) deposit 10% of the purchase price with the
Partnership.

     SECTION 9.3    INTERESTS GRANTED TO KEY PERSONNEL. In order to attract
qualified personnel or to reward personnel (collectively, "Key Personnel') for
their efforts, the General Partner has the right to grant Units and Limited
Partnership interests and options to acquire Units and Limited Partnership
interests to such persons in exchange for their future services. The grant of
such Limited Partnership interests shall not be subject to the preemptive
rights provided for in Section 9.2 above. Incident to granting any such
Limited Partnership interests and notwithstanding anything in this Agreement
to the contrary, the terms of this Agreement may be amended by the General
Partner without the consent of the Limited Partners in order to provide for
the rights and duties of such additional Limited Partners. In the event such
Additional Limited Partners are admitted to the Partnership by the General
Partner, the Ownership Percentage Interests of each existing Partner shall be
adjusted on a pro rata basis

                                     24

<PAGE>

and the Ownership Percentage Interests of such Additional Limited Partners
shall be established by the General Partner. The above notwithstanding, unless
the Approval of the Class A Limited Partners is obtained, the General Partner
shall not, in any calendar year of the Partnership, grant to Key Personnel
Units, Limited Partnership interests or options to acquire the same, to the
extent that the aggregate amount of such Units, Limited Partnership interests
and options to acquire the same, constitute more than 10% of the outstanding
Units of the Partnership at the beginning of such calendar year.

                                    ARTICLE 10.

                           TERMINATION, DEATH, BANKRUPTCY

     SECTION 10.1   TERMINATION OF AGREEMENT. Upon dissolution of the
Partnership and termination of this Agreement, the General Partner or the
liquidator, as the case may be, shall promptly liquidate the affairs of the
Partnership by discharging all debts and liabilities of the Partnership and by
distributing all remaining assets in cash or in kind, or partly in cash and
partly in kind, in accordance with Sections 11.2 and 11.3 hereof.

     SECTION 10.2   NO RECOURSE. Upon liquidation and termination of the
Partnership, each Limited Partner shall look solely to the assets of the
Partnership for the return of his investment, and such Limited Partner shall
have no recourse or further right or claim in connection therewith against the
General Partner or any other Limited Partner. In winding up the affairs of the
Partnership and distributing its assets, the General Partner or liquidator, as
the case may be, shall set up a reserve to meet any contingent or unforeseen
liabilities or obligations and deposit funds for such purpose, together with
funds held by the Partnership for distribution to Partners which remain
unclaimed after a reasonable period of time, with an escrow agent for the
purpose of disbursing such reserves and funds. The General Partner or
liquidator, as the case may be, shall have sole discretion in establishing and
maintaining such reserves and the amount thereof. The escrow agent is
authorized and directed at the expiration of such period as the liquidator
shall deem advisable, to distribute the balance thereafter remaining in the
manner provided in Article 11.

     SECTION 10.3   DEATH, INCAPACITY OR BANKRUPTCY. The death, legal
incapacity or bankruptcy of a Limited Partner (or, in the case of a Limited
Partner that is a partnership, joint venture, association, corporation or
trust, in its insolvency, dissolution or bankruptcy) shall not dissolve nor
terminate the Partnership. In such event, the personal representative,
guardian or other successor in interest of such Limited Partner shall have the
rights of a Limited Partner for the sole purpose of settling the estate of
such Limited Partner and may sell or transfer the Unit(s) of such Limited
Partner only pursuant to the provisions of Article 8.

                                     ARTICLE 11.

                              DISSOLUTION AND WINDING UP

     SECTION 11.1   DISSOLUTION. The Partnership shall be dissolved only upon
the happening of any of the following events:

          a.   The expiration of the term of the Partnership set forth in
Section 2.5 hereof;

          b.   Any disposition by the Partnership of all or substantially all
of its assets;

          c.   The General Partner elects to dissolve (provided such election
takes place after January 1, 2001); or

          d.   The withdrawal, termination (by the filing of articles of
dissolution of the General Partnership if it is a limited liability company)
or bankruptcy of the General Partner, unless the Partnership is continued
pursuant to the written consent of the Limited Partners owning at least 15% of
the Ownership Percentage Interests of all the Partners.

Upon dissolution, the General Partner or liquidator, as the case may be, shall
proceed with reasonable promptness to liquidate the business of the
Partnership. The Partners shall share in the profits and losses of the
business during the period of liquidation pursuant to the provisions of
Article 6.

     SECTION 11.2   DISTRIBUTION UPON LIQUIDATION. Upon dissolution and
termination of the Partnership, any proceeds of liquidation shall be applied
in the following order of priority and according to the following procedures:

          a.   To pay debts and liabilities of the Partnership (including
loans or advances by the Partners) not otherwise adequately provided for by
reserves held by the Partnership, and the expenses of liquidation;

          b.   To set up reasonable reserves for any remaining contingent or
unforeseen liabilities of the Partnership not otherwise provided for, to be
maintained in a regular trust fund account for a reasonable period of time and
if any excess funds thereafter remain, then to be distributed pursuant to this
Section 11.2;

          c.   After giving effect to all contributions and all prior
distributions, and after all Net Income, Net Loss and other items have been
allocated in accordance with Article 6, to the Partners in accordance with and
to the extent of their respective positive Capital Accounts; and

                                     26

<PAGE>

          d.   Liquidating distributions shall then be made to and among the
Partners based upon their distribution rights provided for in Section 7.2.
PURSUANT TO SECTION 4.4 HEREOF, IF ANY PARTNER HAS A DEFICIT BALANCE IN THE
PARTNER'S CAPITAL ACCOUNT FOLLOWING LIQUIDATION OF THE PARTNER'S INTEREST AS
DETERMINED AFTER TAKING INTO ACCOUNT ALL CAPITAL ACCOUNT ADJUSTMENTS FOR THE
PARTNERSHIP'S TAXABLE YEAR IN WHICH SUCH LIQUIDATION OCCURS, SAID PARTNER
SHALL NOT BE OBLIGATED TO RESTORE THE AMOUNT OF SUCH DEFICIT BALANCE TO THE
PARTNERSHIP. It is the express intention of the Partners to override the
holding of PARK CITIES CORPORATION V. BYRD, 534 S.W.2d 668 (Tex. 1976), as
contemplated herein, and to satisfy the economic effect requirements of
Subchapter K of the Code by the use of the qualified income offset provided
in Section 6.3 hereof.

     SECTION 11.3   LIQUIDATION. The General Partner shall act as liquidator,
except in the event of the withdrawal, dissolution or bankruptcy of the
General Partner, in which case a Majority in Interest of the Limited Partners
shall appoint one or more liquidators. A reasonable time shall be allowed for
the orderly liquidation of the assets of the Partnership and the discharge of
liabilities to creditors so as to enable the liquidator to minimize the normal
losses attendant upon the liquidation. Each of the Partners shall be furnished
with a statement which shall set forth the assets and liabilities of the
Partnership as of the date of complete liquidation.

     SECTION 11.4   GAINS OR LOSSES IN PROCESS OF LIQUIDATION. Any property
distributed in kind in liquidation shall be treated as though the property
were sold at its fair market value and the cash proceeds were distributed. The
difference between the value of the property distributed in kind and its book
value shall be treated as a gain or loss on sale of the property and shall be
credited to or charged against the interest of the Partners in the proportions
set forth in Article 6. In the event there is Partnership property which has
not been sold and the undivided interests distributed to the respective
Partners, such property will be distributed subject to such liens,
encumbrances, restrictions, contracts, obligations, commitments or
undertakings as existed with respect to such property at the time acquired by
the Partnership or were subsequently created or entered into by the
Partnership, and otherwise not released or terminated.

                                     ARTICLE 12.

                                  POWER OF ATTORNEY

     SECTION 12.1   APPOINTMENT OF GENERAL PARTNER. By execution hereof, the
Limited Partners, irrevocably constitutes and appoints the General Partner as
each such Limited Partner's true and lawful attorney-in-fact and agent with
full power and authority to act in his, her or its name and place in
executing, filing and recording (i) any documents or statements required to
change the registered office and/or registered agent of the Partnership, (ii)
this Agreement and the Certificate of Limited Partnership, (iii) any
amendments or restatements

                                     27

<PAGE>

to the Certificate of Limited Partnership required to reflect the admission of
a new General Partner, the withdrawal of a General Partner, a change in name
of the Partnership or other proper amendments made in accordance with Article
13, (iv) a certificate of cancellation upon the completion of the winding up
of the Partnership, (v) any documents or certificates required by law to merge
the Partnership with another limited partnership or other entity as permitted
by this Agreement, (vi) any documents or certificates required to be filed as
a result of the admission of additional or substitute General Partners or
Limited Partners, (vii) any amendments to this Agreement incident to admitting
new Limited Partners in accordance with Article 9 of this Agreement, and
(viii) any amendments to this Agreement which do not affect the rights and
obligations of the Partners but are made to correct a mistake or an omission
to this Agreement. Each Limited Partner further authorizes such
attorney-in-fact to take any further action which such attorney-in-fact shall
consider necessary or advisable in connection with any of the foregoing,
hereby giving such attorney-in-fact full power and authority to do and perform
each and every act or thing whatsoever requisite or advisable to be done in
and about the foregoing as fully and to the same extent as each such Limited
Partner might or could do if personally present, hereby ratifying and
confirming all that such attorney-in-act shall lawfully do or cause to be done
by virtue hereof; provided, that in no event may the attorney-in-fact utilize
this power of attorney to cast any vote or consent of the undersigned other
than as to matters with respect to which the attorney-in-fact is specifically
authorized so to act hereunder or which the undersigned has consented to in
writing. Each Limited Partner has and does hereby agree to execute any and all
additional forms, documents or instruments as may be reasonably necessary or
required by each Limited Partner to evidence this power of attorney.

     This power of attorney is coupled with an interest, is irrevocable,
survives the death, incompetency, termination or dissolution of any Limited
Partner, and is binding on any assignee of all or part of a Partnership
interest hereunder. Each Limited Partner agrees to be bound by any
representation made by the attorney-in-fact acting in good faith pursuant to
such power of attorney, and hereby waives any and all defenses which may be
available to protest, negate or disaffirm the actions of the attorney-in-fact
taken in good faith under such power of attorney.

                                    ARTICLE 13.

                                     AMENDMENTS

     SECTION 13.1   AUTHORITY TO AMEND. Except as otherwise expressly provided
for herein, this Agreement may be amended with the consent of the General
Partner and the Approval of the Class A Limited Partners.

     SECTION 13.2   NOTICE OF AMENDMENTS. A copy of any amendment to be
approved by the Limited Partners shall be mailed in advance to such Limited
Partners.

                                MERGER OF PARTNERSHIP

     Pursuant to the Act, and with the prior written consent the General
Partner the Partnership may adopt a plan of merger and may merge with one or
more domestic or foreign limited partnerships, corporations, general
partnerships, limited liability companies, associations or other legal entity
organized pursuant to the laws of the state of Texas or any other state to the
extent of such laws or the constituent documents of such entity would permit
such entity to enter into a merger with the Partnership. The approval of the
Class A Limited Partners shall be required to approve such merger unless all
of the holders of Units will receive the same form and amount of consideration
per Unit, or if any holders are given an option as to the form and amount of
consideration to be received, all holders are given the same option.

                                     ARTICLE 15.

                                   PUBLIC OFFERING

     Notwithstanding anything herein to the contrary, the General Partner is
authorized, without the consent of the Limited Partners, to cause the
Partnership to merge with a new corporation or to contribute all of the
Partnership's assets and liabilities to a new corporation, incident to a
public offering of the stock of such successor entity, provided that the
offering raises at least $10,000,000. In such event, the Partnership will be
terminated and each Partner will receive, incident to such merger or transfer,
shares of stock in the successor entity, in proportion to each Partner's
respective positive Capital Account balance adjusted by treating the
Partnership as having liquidated and gains and losses allocated in accordance
with Section 11.4 hereof.

                              PROTECTION OF PARTNERSHIP
                          INFORMATION/BUSINESS OPPORTUNITIES

     All Partners, and their respective officers, directors, members, managers
and employees (including Miller and Weston) acknowledge and agree that the
Partnership has and will continue to develop proprietary information which is
essential for the success of the Partnership. Such information, includes but
is not limited to marketing plans, strategies, financial data, customer lists,
supplier lists, source code, business ideas (collectively, the "Confidential
Information'), whether oral or embodied in documents (including writings,
drawings, graphs, charts, photographs, phonorecords, video recordings, and
other data compilations from which information can be obtained) or tangible
things. The Partners agree to keep the Confidential Information secret at all
times, and not to disclose such information to any third party without the
consent of the General Partner. The Partners and their

                                     29

<PAGE>

respective officers, directors, members, managers and employees (including
Miller and Weston) all agree, and shall be prohibited from using the
Confidential Information for any purpose other than the purpose of the
Partnership.

     All of the Partners, for so long as they own Units or Limited Partnership
interests (whether directly or indirectly), agree to promptly bring to the
attention of the General Partner and the Partnership, any business opportunity
which become known to them which relates to the business of the Partnership.
The above notwithstanding, the parties acknowledge that Weston and Miller
shall have no duty to bring any business opportunity to the Partnership unless
the business opportunity relates to Partnership's core business activity at
the time, which is currently, commercially developing the Concept. Pursuant to
a separate agreement between the Partnership, Weston and Miller, Weston and
Miller have agreed that they will not compete with the core business
activities of the Partnership for so long as they control the General Partner
and for a period of one year after they lose control of the General Partner.

     SECTION 16.1   LIABILITY OF GENERAL PARTNER. The General Partner, its
officers, directors, representatives, employees and agents shall not be liable
to the Partnership or to the Limited Partners for losses sustained or
liabilities incurred as a result of any error in judgment or mistake of law or
fact (including simple negligence) or for any act done or omitted to be done
in good faith in conducting the Partnership business, unless such error,
mistake, act or omission was performed or omitted fraudulently or in bad faith
or constituted gross negligence or self-dealing.

     SECTION 16.2   INDEMNIFICATION OF THE GENERAL PARTNER. THE PARTNERSHIP
SHALL INDEMNIFY THE GENERAL PARTNER, ITS OFFICERS, DIRECTORS, REPRESENTATIVES,
EMPLOYEES AND AGENTS (collectively referred to as the "GENERAL PARTNER" for

PARTNERSHIP, OR OTHERWISE ACTING AS THE GENERAL PARTNER OF THE PARTNERSHIP, TO
THE MAXIMUM EXTENT PERMITTED UNDER THE ACT OR OTHERWISE BY TEXAS LAW, BUT ONLY
TO THE EXTENT THAT THE SAME WERE NOT CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF THE GENERAL PARTNER.

                              FIRST AMENDMENT TO
                        AGREEMENT OF LIMITED PARTNERSHIP

                                      OF

                               RACKSPACE, LTD.

     This First Amendment to Agreement of Limited Partnership of
(hereinafter referred to as the "Agreement") is made effective the 29th day
of September, 1999 (the "Effective Date"), Rackspace, Ltd. (the
"Partnership"), Macroweb, LC, a Texas limited liability company (the "General
Partner" or "Macroweb"), Trout, Ltd, a Texas limited partnership ("Trout"),
Richard Yoo ("Yoo"), Patrick Condon ("Condon") and Dirk Elmendorf
("Elmendorf) (Macroweb, Trout, Yoo, Condon and Elmendorf are sometimes
referred to herein as the "Partners"). This Agreement amends the Agreement of
Limited Partnership between the parties hereto dated December 29, 1999 (the
"Partnership Agreement").

     WHEREAS, Exeter Financial, LC ("Exeter") advanced $1,050,000.00 to the
Partnership pursuant to the Credit Agreement dated December 29, 1999; and

     WHEREAS, Trout caused Exeter to commit to advance the Partnership an
additional $500,000 over the next six months, as needed by the Partnership
(the "Second Financial Commitment") of which $225,000.00 has been advanced to
the Partnership as of the date of this Agreement, which commitment is set
forth in the agreement entitled "Second Financial Commitment" of even date
herewith;

     WHEREAS, as of the Effective Date of this Amendment, the Partnership
owes Exeter $1,308,139.73 (principal and interest)(the "Outstanding
Balance"); and

     WHEREAS, incident to obtaining the Second Financial Commitment, the
Partnership and the Partners have agreed to convert $1,050,000.00 of the
outstanding principal balance and $32,531.51 of accrued but unpaid interest
(the "Converted Debt") to equity in the Partnership; and

     WHEREAS, Trout has acquired the right to receive the Converted Debt
from Exeter and therefore the $1,082,531.51 of contributed capital resulting
from the conversion will be credited to Trout's capital account and Trout's
Ownership Percentage Interest will be increased pursuant to the provisions
set forth below.

     NOW, THEREFORE, FOR AND IN CONSIDERATION OF THE MUTUAL PROMISES HEREIN
MADE, THE PARTIES AGREE AS FOLLOWS:

     1. DEBT CONVERSION.  Trout represents and warrants that it owns the
Converted Debt pursuant to an agreement between Trout and Exeter whereby
Trout purchased the converted Debt from Exeter and as represented by Exeter
under the Second Financial Commitment. Trout hereby contributes the Converted
Debt to the Partnership and as a result, (i) Trout's capital

<PAGE>

account is increased by $1,082,531.51 and (ii) Trout receives an additional
190,476.19 Units in the Partnership.

     2. RESULT OF DEBT CONVERSION.  The Partners and the Partnership agree
that as a result of the Debt Conversion, the Partners (and assignees), the
number of Units owned by them and their respective Ownership Percentage
Interests are as follows:

<TABLE>
<CAPTION>

     Partner                      Units                    Ownership Percentage Interest
     -------                      -----                    -----------------------------
<S>                          <C>                           <C>
     Macroweb                       1,000 Units                     .084%
     Trout                     699,476.19 Units                   58.756%
     Yoo                          360,000 Units                    30.24%
     Condon                        80,000 Units                     6.72%
     Elmendorf                     40,000 Units                     3.36%

     Bell (assignee only)           5,000 Units                      .42%

Total Units Outstanding      1,090,476.19 Units                   100.00%

</TABLE>

     3. Capital Contribution of Trout.  Under the Partnership Agreement,
Trout agreed to initially contribute $200,000.00 to the Partnership, but
mistakenly contributed $192,369 rather than $200,000.00. The Partnership and
Trout agree that, as of the date hereof, Trout owes the Partnership $8,090.95
($7,631.00 principal and $495.95 interest)(the "Amount Owed"). Trout agrees
to pay the Amount Owed to the Partnership within 30 days of the date hereof.

     Executed by the Partners and the Partnership this 11 day of November,
1999, but made effective on the date first stated above.

                           AGREEMENT OF LIMITED PARTNERSHIP

                                          OF

                                   RACKSPACE, LTD.

     This Second Amendment to Agreement of Limited Partnership of Rackspace,
Ltd. (hereinafter referred to as the "Second Amendment") is made effective
the 30th day of November, 1999 (the "Effective Date"), by and among
Rackspace, Ltd. (the "Partnership"), Macroweb, LC, a Texas limited liability
company (the "General Partner" or "Macroweb"), Trout, Ltd., a Texas limited
partnership ("Trout'), Richard Yoo ("Yoo"), Patrick Condon ("Condon") and

sometimes referred to herein as the "Existing Partners"), and Isom Capital
Partners I, L.P. ("Isom"), First Inning Investors, L.P. ("First Inning"), The
Hamilton Companies LLC, a Colorado limited liability company ("Hamilton"),
Weston Investment Interests, LLC, a Nevada limited liability company ("Weston
Entity"), and MiniPat & Company, Ltd., a Texas limited partnership
("MiniPat"). This Second Amendment amends the Agreement of Limited
Partnership dated December 29, 1999 between the Existing Partners
(hereinafter referred to as the "Agreement" or "Partnership Agreement").
Except as amended by this Second Amendment and by the First Amendment to
Agreement of Limited Partnership of Rackspace, Ltd., the terms of the
Partnership Agreement shall continue in full force and effect. Capitalized
terms used herein shall, unless otherwise specified, have the meanings
assigned to them in the Partnership Agreement.

     WHEREAS, Trout, the Class B Limited Partner, desires to purchase
additional Units in the Partnership;

     WHEREAS, Isom, First Inning, Hamilton, Weston Entity, and MiniPat desire
to purchase Units in the Partnership and to become Limited Partners in the
Partnership pursuant to the terms hereof.;

     WHEREAS, the Partnership and the Existing Partners desire to have Trout,

in the Partnership as set forth herein and to have such persons become
Limited Partners of the Partnership.

     NOW, THEREFORE, FOR AND IN CONSIDERATION OF THE MUTUAL PROMISES HEREIN
MADE, THE PARTIES AGREE AS FOLLOWS:

     1.   ADMISSION OF NEW PARTNERS. Upon the execution of this Second
Amendment by all the parties hereto, Isom, First Inning, Hamilton, Weston
Entity, and MiniPat shall become Additional Limited Partners of the
Partnership as "Class C Limited Partners," having the rights and interests
set forth in this Second Amendment. For the purposes of the Partnership
Agreement, the

SECOND AMENDMENT TO AGREEMENT
OF LIMITED PARTNERSHIP OF RACKSPACE, LTD.                                      1

<PAGE>

Class C Limited Partners are included in the definition of "Partner" and
"Limited Partner." The Units issued to MiniPat pursuant to this Second
Amendment shall not be subject to the repurchase and sale provisions of
Section 8.1 hereof, even though MiniPat is owned or controlled by Condon.

     2.   INCREASE IN NUMBER OF UNITS. Section 5.2 of the Partnership
Agreement permits the General Partner to issue up to Ten Million Units to
Additional Limited Partners. The parties agree to increase the number of
Units which may be issued under Sections 5.2 and 9.1 of the Partnership
Agreement by the General Partner to One Hundred Million Units. In addition,
the number of Units outstanding as of the date of this Second Amendment
(1,190,476.19) shall be split on a 10 for 1 basis such that number of Units
outstanding shall be increased by a multiple often to 11,904,761.9 (prior to
the issuance of the additional Units contemplated herein) and the number of
Units (and options to acquire Units) which may be issued or granted by the
General Partner to Key Personnel under Section 9.3 is increased by a multiple
of ten.

     The term "Unit" in the Partnership Agreement shall be amended to read:
"Unit. A unit of ownership in the Partnership initially represents a .00001%
Ownership Percentage Interest and the rights and interests of a Partner under
this Agreement, subject to adjustment upon the issuance of additional Units;
provided that all Units at any time outstanding shall represent the same
fractional parts of the Ownership Percentage Interests of the Limited
Partners.

     3.   CONTRIBUTION OF CAPITAL.

          a.   Upon the execution of this Second Amendment, Isom, First
Inning, Trout and Condon shall contribute the amounts set forth below to the
Partnership (the "New Contributions to Capital"):

<TABLE>

     <S>                 <C>
     Isom:               $2,560,000.00
     First Inning:       $1,300,000.00
     Hamilton:           $  500,000.00
     Weston Entity:      $  750,000.00
     Trout:              $  500,000.00
     Condon:             $  200,000.00

     Total Contribution: $5,810,000.00

</TABLE>

     The $500,000.00 contributed by Trout consists of conversion of existing
debt of the Partnership in that amount (including principal and interest)
(the "Existing Debt"). All other contributions are made in cash, except for
the Weston Entity contribution which is being made in the form of a
short-term promissory note. The Existing Debt constitutes advances made by
Exeter Financial, LC to the Partnership. By separate agreement, Trout has
acquired from Exeter Financial, LC the right to be repaid the Existing Debt.
Contemporaneously with the execution of this Second Amendment, Trout and
Exeter Financial, LC have delivered a certificate evidencing that no sums are
owed to either of them by the Partnership for advances made by either of
Trout or Exeter

OF LIMITED PARTNERSHIP OF RACKSPACE, LTD.                                      2

Financial, LC. The $500,000.00 contribution by Trout satisfies and discharges
the obligation of Exeter to advance $500,000.00 to advance such sum to the
Partnership pursuant to the Second Financial Commitment dated September 29,
1999.

     b.   Contemporaneously with the $1,300,000.00 contribution made by
First Inning, the Partnership shall enter into the agreement ("Option
Agreement") attached hereto as EXHIBIT A entitled "Option for Investment"
with First Inning's general partner, Trango Capital L.L.C. ("Trango"),
pursuant to which Trango has the right, but not the obligation to contribute
$800,000.00 to the Partnership and receive Units as a Class C Limited
Partner. The purchase price per Unit acquired by Trango will be $2.10 per
Unit subject to adjustment as provided in the Option Agreement. The parties
expressly agree that upon the Closing (as defined in the) Option Agreement,
Trango shall acquire additional Units in accordance with the Option
Agreement. At such time, the General Partner, at its option, shall have the
right to revalue the Partnership property in accordance with Treasury
Regulation 1.704-1(b)(2)(iv)(f).

          c.   At any time on or prior to January 17, 2000 (the "Expiration
Date"), Hamilton shall have the option, but not the obligation, to contribute
an additional $500,000.00 to the Partnership and receive additional Units as
a Class C Limited Partner. The purchase price per Unit pursuant to this
option shall be $2.10 per Unit. The issuance of these Units shall not be
subject to the preemptive rights in Section 9.2 of the Partnership Agreement.
The option shall be exercisable by Hamilton delivering to the General Partner
written notice of such exercise at any time before the Expiration Date.  If
this option shall be exercised subsequent to any recapitalization, merger,
consolidation, combination or exchange of Units, reorganization or
liquidation of the Partnership occurring after the date hereof, as a result
of which securities of any class shall be issued in respect of outstanding
Units, Hamilton shall receive, for the aggregate price paid upon such
exercise, the aggregate number and class of securities which Hamilton would
have received if this option had been exercised immediately prior to such
recapitalization, merger, consolidation, combination or exchange of Units,
reorganization or liquidation.

     This option shall not be transferable or assignable by Hamilton, except
upon the prior written consent of the General Partner which consent may be
withheld in the General Partner's sole discretion.

     4.  ADJUSTMENT TO CAPITAL ACCOUNTS. The parties to this Second Amendment
have made a determination that the fair market value of the assets of the
Partnership, immediately prior to the contributions required by this Second
Amendment, is $25,000,000.00 (the "Current Valuation"). However, the parties
further agree that the value of the assets is extremely speculative and may
in fact be substantially more or substantially less than $25,000,000.00. The
number of Units received by Isom, First Inning, Trout, Hamilton, Weston
Entity, and MiniPat are based upon the parties' mutual determination that the
value of the Partnership's assets immediately prior to closing of the sale of
such additional Units is $25,000,000.00. The Capital Accounts of each of the
Existing Partners shall be adjusted in accordance with Treasury Regulation
1.704-1(b)(2)(iv)(f) to reflect the Current Valuation as follows:

     arising from the transactions contemplated by the Second

     Amendment (including, without limitation, any cancellation of
     indebtedness income of the Partnership resulting from Trout's
     acquisition of the right to be repaid the Existing Debt (as defined in
     the Second Amendment) and the contribution of such right to the
     Partnership pursuant to Section 3 of the Second Amendment) shall be
     deemed to have been realized and recognized by the Partnership on or
     before the date of the Second Amendment and shall be allocated solely to
     the Existing Partners.

          SECTION 6.2    ALLOCATIONS OF PARTNERSHIP NET INCOME FOR PERIODS AFTER
     THE SECOND AMENDMENT. Partnership net income (determined for purposes of
     maintaining the Partners' Capital Accounts and after any allocations for
     such taxable year or period pursuant to Section 6.4) allocable to
     taxable years or periods beginning after the date of the Second
     Amendment shall be allocated to the Partners as follows:

               (a)  First, to the General Partner until the cumulative
          allocations of net income made to the General Partner pursuant to
          this Section 6.2(a) equal the cumulative allocations of net loss
          previously made to the General Partner pursuant to the proviso
          clause of Section 6.3(b);

               (b)  Second, to the Limited Partners in proportion to and to
          the extent of the excess, if any, of (i) the cumulative allocations
          of net loss previously made to them pursuant to Section 6.3(b),
          over (ii) the cumulative allocations of net income previously made
          to them pursuant to this Section 6.2(b); and

               (c)  Third, to the Partners in proportion to their Ownership
          Percentage Interests.

          SECTION 6.3 ALLOCATIONS OF PARTNERSHIP NET LOSS FOR PERIODS AFTER
     THE SECOND AMENDMENT. Partnership net loss (as determined for purposes
     of maintaining the Partners' Capital Accounts and after any allocations
     for such taxable year or period pursuant to Section 6.4) allocable to
     taxable years or periods beginning after the date of the Second
     Amendment shall be allocated to the Partners as follows:

               (a)  First, to the Partners in proportion to and to the extent
          of the excess, if any, of (i) the cumulative allocations of net
          income previously made to them pursuant to Section 6.2(c), over
          (ii) the cumulative allocations of net loss previously made to them
          pursuant to this Section 6.3(a); and

               (b)  Second, to the Partners in accordance with their

          such loss allocation would cause or increase a deficit balance in
          any Limited Partner's Capital Account (after adjustment for any
          applicable increases described in the penultimate sentences of
          Treasury regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5) and
          after any applicable decreases described in Treasury regulations
          Sections 1.704-1(b)(2)(ii)(d)(4), (5) and (6)

          (hereinafter, a Partner's "Adjusted Capital Account"), the amount
          thereof shall instead be allocated to Limited Partners with
          positive Adjusted Capital Accounts, if any, in proportion to and to
          the extent of their positive Adjusted Capital Accounts, and the
          balance, if any, shall be allocated to the General Partner.

          SECTION 6.4    SPECIAL ALLOCATIONS OF ITEMS OF PARTNERSHIP INCOME,
     GAIN, LOSS AND DEDUCTION FOR PERIODS AFTER THE SECOND AMENDMENT. Before
     giving effect to allocations of net income or net loss for a taxable
     year or period pursuant to Sections 6.2 and 6.3, the following items of
     Partnership income, gain, loss and deduction (determined for purposes of
     maintaining the Partners' Capital Accounts) shall be specially allocated
     to the Partners, as follows and in the following order of priority:

               (a)  If there is a net decrease in "partnership minimum gain"
          (as defined in Treasury regulations Section 1.704-2(d)), items of
          income and gain (determined in accordance with Treasury regulations
          Section 1.704-2(f)(6))) shall, to the extent required by the
          Treasury regulations, be specially allocated to the Partners in an
          amount equal to each Partner's share of the net decrease in
          partnership minimum gain (determined in accordance with Treasury
          regulations Section 1.704-2(g)). This Section 6.4(a) shall be
          applied consistently with, and subject to the exceptions contained
          in, the minimum gain chargeback requirements of Treasury
          regulations Section 1.704-2(f).

               (b)  If there is a net decrease in "partner nonrecourse debt
          minimum gain" (as defined in Treasury regulations Section
          1.704-2(i)(2)), items of income and gain (determined in accordance
          with the provisions of Treasury regulations Section 1.704-2(i)(4))
          shall, to the extent required by the Treasury regulations, be
          specially allocated to the Partners in an amount equal to each
          Partner's share of the net decrease in partner nonrecourse debt
          minimum gain (determined in accordance with the provisions of
          Treasury regulations Section 1.704-2(i)(5)). This Section 6.4(b)
          shall be applied consistently with, and subject to the exceptions
          contained in, the partner nonrecourse debt minimum gain chargeback
          requirements of Treasury regulations Section 1.704-2(i)(4).

               (c)  if a Partner unexpectedly receives any adjustment,
          allocation or distribution described in Treasury regulations
          Sections 1.704-1(b)(2)(ii)(d)(4), (5) or (6) that causes or
          increases a deficit balance in the Partner's Adjusted Capital
          Account, items of income and gain shall be specially allocated to
          the Partner in an amount and manner sufficient to eliminate, to the
          extent required by the Treasury regulations, such deficit balance
          in the Partner's Adjusted Capital Account as quickly as possible,
          provided that an allocation pursuant to this Section 6.4(c) shall
          be made only to the extent that the Partner has a deficit balance
          in its Adjusted Capital Account after all other allocations
          provided for in this Article IV have been tentatively made as if
          this Section 6.4(c) were not in this Agreement. This Section 6.4(c)
          shall be interpreted

          consistently with the "qualified income offset" provisions of Treasury
          regulations Section 1.704-1(b)(2)(ii)(d).

               (d) If any Partner has a deficit balance in its Capital
          Account at the end of any taxable year or period that is in excess
          of the sum of any amount the Partner is obligated to restore
          pursuant to this Agreement and any amount the Partner is treated as
          obligated to restore pursuant to the penultimate sentences of
          Treasury regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5),
          items of income and gain in the amount of such excess shall be
          specially allocated to the Partner as quickly as possible, provided
          that an allocation pursuant to this Section 6.4(d) shall be made
          only to the extent of any such excess determined after all other
          allocations provided for in this Article IV have been tentatively
          made as if Section 6.4(c) and this Section 6.4(d) were not in this
          Agreement.

               (e)  "Nonrecourse deductions" (as defined in Treasury
          regulations Section 1.704-2(c)) shall be specially allocated to,
          and "excess nonrecourse liabilities" (as defined in Treasury
          regulations Section 1.752-3(a)(3)) shall be shared among, the
          Partners in proportion to their Ownership Percentage Interests.

               (f)  "Partner nonrecourse deductions" (as defined in Treasury
          regulations Section 1.704-2(i)(2)) shall be specially allocated to
          the Partners who bear the economic risk of loss for the liability
          to which those deductions are attributable, determined in
          accordance with the principles of Treasury regulations Section
          1.704-2(i)(l).

               (g) To the extent an adjustment to the adjusted tax basis of
          any Partnership asset under Code Sections 734(b) or 743(b) is
          required to be taken into account in determining Capital Accounts
          under Treasury regulations Section 1.704-1(b)(2)(iv)(m), the amount
          of the Capital Account adjustment shall be treated as an item of
          income (if positive) or loss (if negative) and shall be specially
          allocated to the Partners consistent with the manner in which their
          Capital Accounts are required to be adjusted by such Treasury
          Regulation.

               (h)  To minimize any distortions in the manner that the
          Partners would have shared Partnership distributions if the special
          allocations required by Sections 6.4(a) through (g) had not been
          part of this Agreement, the General Partner shall specially
          allocate to the Partners offsetting items of income, gains, loss or
          deduction so that the net amounts allocated to each Partner
          pursuant to Section 6.2, Section 6.3 and this Section 6.4 will, to
          the extent reasonably possible, equal the net amounts that would
          have been allocated to each Partner pursuant to Sections 6.2 and
          6.3 had Sections 6.4(a)-(g) not been part of this Agreement. In
          exercising its authority hereunder, the General Partner may
          consider any expected future allocations pursuant to Sections
          6.4(a) and 6.4(b) that are likely to offset other allocations made
          pursuant to Sections 6.4(a) through 6.4(g).

          SECTION 6.5    ALLOCATIONS FOR FEDERAL INCOME TAX PURPOSES.

               (a)  Except as provided in Section 6.5(b), for each taxable
          year or period of the Partnership, items of taxable income, gain,
          loss and deduction of the Partnership, determined solely for
          federal income tax purposes, shall be allocated to the Partners in
          the same manner as each correlative item of income, gain, loss,
          and deduction is allocated to the Partners pursuant to Sections
          6.1 through 6.4.

               (b)  In accordance with Section 704(c) of the Code and the
          Treasury regulations thereunder, solely for federal income tax
          purposes, items of taxable income, gain, loss and deduction with
          respect to any Partnership asset other than money that has been
          contributed to the Partnership or revalued on the books of the
          Partnership shall be allocated among the Partners in a manner that
          takes into account the difference, at the time of contribution or
          revaluation, between the adjusted tax basis of the asset and the
          amount by which it is carried on the books of the Partnership for
          purposes of maintaining the Partner's Capital Accounts. Such
          allocations shall be made utilizing the "Remedial Method" described
          in Treasury regulations Section 1.704-3(d). Allocations pursuant to
          this Section 6.5 are solely for federal income tax purposes and
          shall not affect the Partners' Capital Accounts.

          SECTION 6.6.   VARYING INTERESTS. To reflect the varying interests
     of the Partners during any taxable year, net income or net loss and
     items of income, gain, loss and deduction of the Partnership shall be
     determined on a daily, monthly or other basis using any convention or
     method permitted under Code Section 706 and the Treasury regulations
     thereunder, provided that gain or loss arising from dispositions of
     Partnership assets shall be allocated to the Partners on the date of the
     disposition. Notwithstanding the foregoing, for the Partnership's 1999
     taxable year such items shall be allocated as follows:

               a.   The Partnership's books shall be closed as of June 30,
          1999, and net income or net loss and items of income, gain, loss
          and deduction of the Partnership for the period ending on June 30,

          6.1, be allocated to the persons who were Partners during such
          period by assigning an equal portion of each such item to each day
          in such period and allocating the amount assigned to each day among
          the persons who were Partners on such day in accordance with the
          provisions of this Agreement in effect on such day.

     7.   CERTAIN DEFINED TERMS. The defined terms: Loss Recapture
Allocation, Regular Allocation, Regular Loss Allocation and Specially
Allocated Losses contained in Article I of the Partnership Agreement are
deleted.

     8.   DISTRIBUTIONS. Section 7.2 of the Partnership Agreement is amended
and restated in its entirety as follows:

          SECTION 7.2    DISTRIBUTIONS OF CASH AVAILABLE FOR DISTRIBUTION. To
     the extent that Tax Distributions or distributions of Cash Available for
     Distribution are made by the Partnership, such distributions shall be made
     as follows:

     FIRST:         TAX DISTRIBUTIONS. Tax Distributions shall be made to the
                    Partners in an amount equal to the amount of any federal
                    income tax estimated by the General Partner to be incurred
                    by the Partners (such estimate to be made on the assumption
                    that all of the Partners will be taxed at the highest
                    marginal federal income tax rate applicable to individuals,
                    which is currently 39.59%) on their allocable share of any
                    net income or net gain from the Partnership which is
                    recognized for federal income tax purposes during the prior
                    year and not otherwise distributed to the Partners.
                    However, to the extent that a Partner has been allocated
                    losses, no Tax Distributions will be made to the Partner
                    until the cumulative net income and gain of the Partnership
                    allocated to the Partner exceeds the cumulative amount of
                    losses allocated to the Partner. Tax Distributions shall be
                    made not later than February 28th of each year. To the
                    extent the Partnership makes Tax Distributions, subsequent
                    distributions that would have been made pursuant to Sections
                    7.2 Second and 11.2(c) shall first be made among the
                    Partners in a manner that, to the extent possible, will
                    cause the cumulative distributions pursuant to Article 7 and
                    Section 11.2(c) to each Partner to be equal to the amount
                    that would have been distributed to each Partner had Section
                    7.2 First not been part of this Agreement; and
                    notwithstanding Sections 4.4 and 11.2(c) to the contrary,
                    the amount of any such excess distributions to a Partner
                    remaining upon liquidation of the Partnership or the
                    Partner's interest in the Partnership shall be immediately
                    repaid to the Partnership by the Partner for distribution to
                    the other Partners.

     SECOND:        REGULAR DISTRIBUTIONS.  Regular Distributions of the
                    remaining Cash Available for Distribution shall be made to
                    all the Partners in accordance with their Ownership
                    Percentage Interests.

     9.   RIGHTS AND OBLIGATIONS OF CLASS C PARTNERS. The Class C Limited
Partners shall have all of the rights and all of the obligations which apply
to Limited Partners. In addition, the following terms shall apply:

SECOND AMENDMENT TO AGREEMENT
OF LIMITED PARTNERSHIP OF RACKSPACE, LTD.                                     10

<PAGE>

          a.   SECTION 3.2. Section 3.2 of the Partnership Agreement
restricts the General Partner from taking certain actions without the
approval of the Class A Limited Partners (the "Restricted Acts"). Section
3.2 is hereby amended to require the General Partner to obtain the "Approval
of the Class C Limited Partners" before taking the Restricted Act in
question, in addition to the approval of the Class A Limited Partners.

     For the purposes of this Second Amendment, the "Approval of the Class C
Limited Partners" shall mean the approval of 65% of Limited Partners Interest
held by the Class C Limited Partners. A Class C Limited Partner's approval or
consent shall be pursuant to a vote or written consent as provided in Section
16.9.

          b.   SECTION 3.3 Section 3.3 addresses when the General Partner may
be removed or replaced. The parties agree that in the event the General
Partner may be removed and replaced under Section 3.3(a), such removal and
replacement shall require the Approval of the Class A Limited Partners and
the Class C 3 Limited Partners, but at all times subject to the rights
contained in Section 3.3 of the General Partner to reverse the transaction
giving rise to the removal. Provided, however, at any time the General
Partner may be removed upon the approval of 60% of the Limited Partners
Interests. In the event of the dissolution, bankruptcy or resignation of the
General Partner under Section 3.3(b), where a successor General Partner is
appointed which is not owned 100% by Graham M. Weston ("Weston") and Morris
A. Miller ("Miller"), the new General Partner will be selected by and with
the Approval of the Class A Limited Partners and the Class C Limited Partners.

          c.   SECTION 8.2 (RESTRICTIONS ON TRANSFER).  Section 8.2 of the
Partnership Agreement is amended to read in its entirety as follows:

     SECTION 8.2    PROHIBITED DISPOSITIONS.

                         a.   CLASS A PARTNER RESTRICTION.  The Class A Limited
          Partners shall not make any sale, transfer, pledge, assignment or
          other disposition of any of their Units which may be purchased by the
          Partnership pursuant to the Partnership's rights under Section 8.1
          above.  Therefore, as to each Class A Limited Partner, for so long as
          the Partnership has the right to acquire any of such Class A Partners'
          Units in the event that he is no longer employed by the Partnership,
          no disposition of those Units which may be acquired by the Partnership
          under Section 8.1 may be made by such Class A Partner.

                         b.   TRANSFERS PROHIBITED. Except as specifically
          allowed under this Agreement, no Limited Partner may sell, assign,
          transfer, mortgage, encumber, hypothecate, pledge or otherwise dispose
          of all or any part of such Limited Partner's interests in the
          Partnership and any attempt to take such action and any purported
          separate sale, transfer, assignment, mortgage, encumbrance,

SECOND AMENDMENT TO AGREEMENT
OF LIMITED PARTNERSHIP OF RACKSPACE, LTD.                                     11

<PAGE>

          hypothecation, pledge, or other disposition by any Limited Partner
          shall be void. In the event of any sale, transfer, assignment or other
          disposition which is not made in accordance with this Agreement, and
          without herein recognizing such as being permitted or valid, the
          Limited Partner making the same shall remain and continue to be liable
          for the performance of all of its obligations hereunder and the
          Partnership shall continue to make any distributions, if any, to said
          Limited Partner.  All subsequent owners of any Units, or other Limited
          Partnership interests hereunder shall hold same subject to all the
          terms and provisions hereof. To the extent that the provisions of this
          Section 8.2 and the other provisions of this Agreement are followed
          incident to any sale of Units, the transferee of such Units shall
          become a Substitute Limited Partner of the Partnership with the
          written consent of the General Partner, which consent shall not be
          withheld or delayed. With respect to any transfer of all of the Units
          and interests in the Partnership held by Macroweb, the transferee
          shall become the substitute General Partner of the Partnership,
          provided that the provisions of this Section 8.2 and all other
          provisions of this Agreement are followed incident to the sale of such
          Units and interests.

                         c.   RIGHT OF FIRST REFUSAL. Subject to transfers of
          Units of the Class A Limited Partner in accordance with Section 8.1
          above, no Limited Partner (including any assignee of a Limited
          Partner) may propose to make any sale, transfer, pledge, assignment or
          other disposition of all or any part of their Units or other Limited
          Partnership interests (such interests referred to as the "Units
          Offered for Sale") except in exchange for cash or a combination of
          cash and promissory notes. Prior to making such disposition, the
          Limited Partner desiring to make such sale (the "Selling Partner")
          shall first offer his or her Units Offered for Sale to each of the
          other Limited Partners under the same terms and conditions as the
          proposed sale (the "Terms of Sale"). Such offer shall be in writing
          (the "Offer Notice") and delivered to the other Partners, along with
          the name of the proposed purchaser of the Units Offered for Sale. The
          Selling Partner shall provide to the other Partners all information
          regarding the proposed sale and the proposed purchaser, as may be
          reasonably requested by the other Partners. For a period of 15
          Business Days after the date of the Offer Notice is given, a Partner
          may accept the Selling Partner's offer with respect to the portion of
          the Units Offered for Sale that corresponds to the ratio of the
          accepting Partner's Limited Partners interest to the Limited Partners
          Interest of all the other Partners (other than the Selling Partner) by
          giving written notice

SECOND AMENDMENT TO AGREEMENT
OF LIMITED PARTNERSHIP OF RACKSPACE, LTD.                                     12

<PAGE>

          of such acceptance to the Selling Partner and the General Partner.
          Beginning with the expiration of 15 Business Days after the date
          the Offer Notice is given and ending on the 20th Business Day after
          the date the Offer Notice was given, the Partnership or the General
          Partner may, in the sole discretion of the General Partner, accept
          the Seller's offer with respect to all of the remaining portion of
          the Units Offered for Sale by giving written notice of such
          acceptance to the Seller and the other Partners. Unless the other
          Partners and the Partnership (in the aggregate) accept the Seller's
          offer with respect to all of the Units Offered for Sale, the
          Selling Partner's offer shall be deemed rejected in its entirety.
          Upon an election to purchase all of such Units Offered for Sale as
          provided above, the purchasing Partners (and the Partnership as the
          case may be) shall make available to the Selling Partner at the
          offices of the General Partner, an amount equal to ten (10%)
          percent of the purchase price of the Units Offered for Sale as a
          non-refundable deposit. In addition, to the extent that the Terms
          of Sale require a note or notes, the accepting Limited Partners
          shall be required to demonstrate that they have at least the same
          credit worthiness as the proposed purchaser. Payment for the Units
          Offered for Sale shall be made in accordance with the Terms of
          Sale. If the Partners and the Partnership do not elect to purchase
          all the Units Offered for Sale, the Selling Partner shall be free
          to sell all, but not less than all of such Units Offered for Sale
          for a period of sixty (60) days after the expiration of the option
          of the other Partners, provided that any such sale must be made
          under the same terms and conditions and to the same purchaser as
          described in the Terms of Sale. The Selling Partner shall provide
          all information relating to the transferee of the Units Offered for
          Sale which is reasonably requested by the General Partner.

          d.   SECTION 8.3 (TRANSFERS TO A FAMILY MEMBER). Section 8.3 of the
Partnership Agreement is amended to read in its entirety as follows:

          Any Limited Partner shall be permitted to transfer his or her Units or
          other Limited Partner Interests to (i) a Family Member or a trust
          established for the benefit of a Family Member ("Trust"), (ii)
          Affiliates of the Limited Partner, (iii) to the General Partner, (iv)
          to the Partnership, (v) to Persons to whom the interest is transferred
          by reason by the Limited Partner's death or involuntarily by operation
          of law, or (vi) pursuant to a transfer in accordance with the
          provisions of Section 8.2. However, no such transferee shall become a
          Substitute Limited Partner except in accordance with Section 8.6 of
          the Partnership Agreement. It is expressly agreed that

SECOND AMENDMENT TO AGREEMENT
OF LIMITED PARTNERSHIP OF RACKSPACE, LTD.                                     13

<PAGE>

          Trout may transfer its Units to Miller, Weston or any of their Family
          Members or a trust established for the benefit of a Family Member.

In addition, the definition of "Affiliate" shall be amended to read in its
entirety:

                         "AFFILIATE" means a Person who directly or indirectly
          controls, is controlled by, or is under common control with, the
          Person referred to. For this purpose, "control" means the ability to
          direct or cause the direction of the management or affairs of a
          Person, whether through the ownership of voting securities, by
          contract or otherwise.

               e.   SECTION 13.1 (AMENDMENTS TO PARTNERSHIP AGREEMENT). In
such instances when Section 13.1 of the Partnership Agreement requires the
Approval of the Class A Limited Partners, the General Partner shall be
required to obtain both the Approval of the Class A Limited Partners and the
Approval of the Class C Limited Partners. In addition Section 13.1 is further
amended to add a second sentence to read in its entirety: "The consent of
each Limited Partner must be obtained for any amendment which would
materially affect the Limited Partner's rights to distributions (other than
by virtue of additional Capital Contributions by other Partners), its
obligations for Capital Contributions, adversely affect its limited liability
as a Limited Partner, modify the provisions of this SECTION 13.1, or lower
the threshold required by the Partnership Agreement or the Act for obtaining
the vote, consent or approval of the Limited Partners with respect to any
action or undertaking."

               f.   ARTICLE 14 (MERGER OF PARTNERSHIP). The last sentence of
Article 14 Merger of Partnership is deleted and the following shall be added
in its place: "The Approval of the Class A Limited Partners and the Approval
of the Class C Limited Partners shall be required to approve such merger,
unless all of the holders of Units will be given the same or substantially
the same rights as they have pursuant to this Second Amendment (including,
without limitation, preferences, rights of first refusal, options, conversion
rights, preemptive rights, voting rights, or registration rights). Provided,
however, no Approval of the Class A Limited Partners nor Class C Limited
Partners shall be required for a transaction to convert the Partnership to a
corporation (whether by virtue of merger, conversion or other transaction)
which is consummated solely for the purpose of changing the form of entity
used to conduct business of the Partnership, so long as the Limited Partners
have the same or substantially the same rights, obligations and interests in
the new entity as they enjoyed as Partners of the Partnership, including,
without limitation, preferences, rights of first refusal, options, conversion
rights, preemptive rights, voting rights and registration rights, but
excluding any rights to limit the General Partner as provided in Section 3.2
of the Partnership Agreement. In the event any transaction pursuant to this
Article 14 results in the termination of the Partnership, each Partner will
receive, incident to such merger or other transaction, shares of stock in the
successor entity, in proportion to each Partner's then current respective
positive Capital Account balance, as adjusted by treating the Partnership as
having liquidated and gains and losses allocated in accordance with Section
11.4 hereof."

          g.   ARTICLE 15 (PUBLIC OFFERING). Article 15 is amended to read in
its entirety:

          "Notwithstanding anything herein to the contrary, the Partners agree
          that incident to an initial public offering of the securities of the
          Partnership or any successor entity, which raises at least
          $10,000,000.00, the following rights contained in this Agreement shall
          be terminated: (i) preemptive rights, (ii) parallel exit rights, (iii)
          rights of first refusal, and (iv) transfer restrictions (other than as
          required by applicable securities laws)."

          h.   REPRESENTATION ON BOARD OF DIRECTORS.  If the Partnership
converts to a corporation, limited liability company or other entity (whether
by virtue of corporate reorganization, merger, conversion or
otherwise)(herein referred to as the "Successor Entity"): (i) the Class C
Limited Partners, for so long as the Class C Limited Partners hold at least
10% of the equity interests (capital stock, membership interests or
otherwise) of the Successor Entity, they shall have the right to designate
one director or manager of such entity; (ii) Hamilton, for so long as
Hamilton holds at least 2.5% of the equity interests (capital stock,
membership interests or otherwise) of the Successor Entity (either directly
or indirectly through their limited partner interest in Isom), it shall have
the right to designate one director or manager of such entity; and (iii)
Trout, for so long as Trout holds at least 20% of the equity interest
(capital stock, member interest or otherwise) of the Successor Entity, it
shall have the right to designate up to five (5) directors or managers of
such entity. Provided, however, should Hamilton not exercise its option to
purchase $500,000.00 in additional Units prior to the Expiration Date, as
provided in Section 3.c. of this Second Amendment, then its right to
designate a director or manager shall be subject to termination in the
discretion of the Partnership or the Successor Entity. Provided, further,
should Trout elect to waive its right to designate any directors (so that it
has no right to designate any director or manager) in connection with a sale
of securities of the Partnership or Successor Entity which raises
$10,000,000.00 or more, then the Class C Limited Partners and Hamilton will
agree to waive their designation right as well. There shall be not more than
7 directors or managers of the Successor Entity, except upon the consent of
the Class C Limited Partners and Hamilton (so long as Hamilton has a
designation right). The designation of the director or manager by the Class C
Limited Partners shall be determined by a vote of 65% of the Class C Limited
Partners other than Hamilton for so long as Hamilton has a right to designate
a director or manager, and thereafter upon the Approval of the Class C
Limited Partners (including Hamilton).

     10.  DISSOLUTION (SECTION 11.1.c.).  Section 11.1.c. of the Partnership
Agreement is amended in its entirety to read:

                         c.   The General Partner, upon approval of a Majority
          in Interest of the Limited Partners, elects to dissolve (provided such
          election takes place after January 1, 2001).

     11.  MEETING & VOTING OF LIMITED PARTNERS. Section 16.9 of the Partnership
Agreement is amended to read in its entirety as follows:

     SECTION 16.9.  MEETINGS & VOTING BY LIMITED PARTNERS.

                         a.   MEETINGS. Within a reasonable time after each
          fiscal year and at such other times as the General Partner, in its
          sole discretion, shall determine, the General Partner shall call a
          meeting of the Partners for the purpose of discussing the affairs
          of the Partnership and acting on any matter permitted or required
          by this Agreement or the Act to be acted on by the Limited
          Partners. The General Partner shall give not less than ten days
          prior written notice of the meeting, specifying the time and
          location of the meeting and the matters to be discussed or acted
          upon. Meetings may be held at any time during normal business hours
          and at any place within San Antonio, Texas as the General Partner
          may select. Partners may waive notice of or attendance at the
          meeting and may vote in Person, by proxy, by delivering a signed
          written consent specifying its vote for or against a matter to the
          General Partner at or prior to the meeting, or by telephone or
          other electronic communication device. Attendance at a meeting
          shall constitute waiver of notice of the meeting. The General
          Partner or its designee shall chair the meeting and may conduct the
          meeting under such rules as it may reasonably select.

                         b.   VOTING BY LIMITED PARTNERS. Unless by vote
          pursuant to a meeting called in accordance with SECTION 16.9.a, a
          Limited Partner's approval or consent shall be conveyed in writing
          to the General Partner not later than 15 Business Days after the
          date the approval or consent was requested by the General Partner.
          A failure to respond in any such time period shall constitute a
          consent or approval which is consistent with the General Partner's
          recommendation with respect to the proposal. If the General Partner
          receives the necessary vote, approval or consent of the Limited
          Partners to any action, the General Partner shall be authorized and
          empowered to implement such action without further authorization by
          the Limited Partners. The Limited Partners shall have the right to
          consent, approve or vote with respect to a matter only as
          specifically reserved for their consent, approval or vote pursuant
          to this Agreement or any nonvariable provision of the Act. Unless
          otherwise required by this Agreement or any nonvariable provision
          of the Act, the vote, consent or approval of the Limited Partners on
          any matter required or permitted to be submitted to their vote,
          consent or

SECOND AMENDMENT TO AGREEMENT
OF LIMITED PARTNERSHIP OF RACKSPACE, LTD.                                     16

          approval shall be had only by a Majority in Interest of the Limited
          Partners.

                    c.   TIME PERIODS FOR CONSENTS. Notwithstanding anything
          in the Agreement to the contrary, the Class C Limited Partners
          shall not have less than 15 Business Days to make any election or
          give any consent, whether in connection with the election to
          exercise preemptive rights, parallel exit rights or otherwise. In
          the case of exercise of preemptive rights under Section 9.2 of the
          Agreement, the 15 Business Days time period shall commence to run
          upon the Limited Partners' receipt from the General Partner of a
          description (containing all material terms) of the proposed
          offering giving rise to the preemptive rights.  The term "Business
          Day" as used in this Agreement shall mean Monday through Friday,
          except any of those days in any week in which the national banks of
          the U.S.A. are closed for business.

     12.  TAX PROVISIONS. Incident to a sale of Units in compliance with the
terms of the Partnership Agreement, upon request of the transferring Partner,
the General Partner shall, to the extent permitted by law, make the
appropriate election to adjust the basis of Partnership properties pursuant
to Code Sections 754, 755, 734(b) and 743(b), or comparable provisions of
state or local law, in connection with transfers of interests and Partnership
distributions; PROVIDED, HOWEVER, that the General Partner, as a condition to
making any such election, may require any Partner or transferee requesting
such election to pay or make adequate provisions for payment of the
reasonable costs and expenses incurred by the Partnership in making and as a
consequence of making such election.

     13.  REGISTRATION RIGHTS. The Class C Limited Partners and Trout shall
be granted demand and piggy-back registration rights for the Units acquired
pursuant to this Second Amendment, as more particularly set forth in that
certain Registration Rights Agreement by and among the Partnership, the Class
C Limited Partners and Trout entered into contemporaneously with this Second
Amendment.

     14.  PARTIES BOUND. The Class C Limited Partners agree, that by
executing this Second Amendment, they are bound to the terms contained herein
as well as the terms contained in the Partnership Agreement as if they had
become direct signatories to the Partnership Agreement.

     15.  RELATED PARTIES. The parties to the Second Amendment acknowledge
that the Weston Entity may meet the definition of a Related Party of Weston
under the terms of the Partnership Agreement. To the extent that the Weston
Entity does meet the definition of a Related Party of Weston, with the
respect to the issuance of Units to the Weston Entity pursuant to the terms
of this Second Amendment, the parties agree to waive the requirements of
Section 3.2(a) of the Partnership Agreement.

SECOND AMENDMENT TO AGREEMENT
OF LIMITED PARTNERSHIP OF RACKSPACE, LTD.                                     17

<PAGE>

     16.  KEY MAN LIFE INSURANCE. For a period of two (2) years, the
Partnership shall maintain Key Man Life Insurance on the life of Graham M.
Weston in an amount of not less than $4,000,000.00.

     17.  OPTIONS TO KEY PERSONNEL.

          a.   Section 9.3 to of the Partnership Agreement permits the
General Partner to issue Units and options to acquire Units to Key Personnel.
The Partners desire to cap the number of Units, Limited Partnership
Interests, or options to acquire the same at 10% of the outstanding Units.
Therefore, the last sentence of Section 9.3 is hereby amended to read in its
entirety: "The above notwithstanding, except upon the Approval of the Class A
Limited Partners and the Approval of the Class C Limited Partners (including
the affirmative approval of Isom), the General Partner shall not grant to any
Key Personnel, any Units, Limited Partnership Interests, or options to
acquire the same, to the extent that the aggregate amount of all such
interests granted to Key Personnel would (if fully exercised) constitute more
than 10% of the then outstanding number of Units or Limited Partners
Interests of the Partnership." All the options contemplated to be granted to
the Certain Key Employees (as defined below) and First Inning pursuant to
this Second Amendment and the Option Agreement shall be counted towards the
10% cap on such interests.

          b.   Currently, Richard Yoo ("Yoo"), Pat Condon ("Condon") and Dirk
Elmendorf ("Elmendorf") are subject to employment agreements with the
Partnership and are paid annualized salaries of $3,000.00 per month, with the
right to receive an annual bonus of $15,000.00 to the extent that the
Partnership has repaid all principal owing to Exeter Financial, LC. If the
bonus were paid and spread throughout the year, the monthly salary of Yoo,
Condon and Elmendorf would be $4,250.00. Miller and Weston are employees at
will and are not currently being paid a salary, but may be paid an annual
salary not in excess of $100,000 in 2000, $110,000 in 2001 and $121,000 in
2002.  The parties agree that the General Partner may issue options to Yoo,
Condon, Elmendorf, Miller and Weston (collectively "Certain Key Personnel")
to acquire Units, in lieu of their salary, in accordance with the following
general terms, SUBJECT TO execution of definitive option agreements:

               (i) Yoo, Condon and Elmendorf may elect at the beginning of
each calendar quarter, during 2000, to forgo some or all of their monthly
salary and earn the right to receive options to acquire Units. Each of Yoo,
Condon and Elmendorf, to the extent that any of them elect not to continue
their salary at $3,000 per month for the next twelve months and not receive a
bonus (or elect to receive such amount less than $4,250 per month) he will
earn options to acquire such number of Units determined by dividing the
difference between $12,750 (3 months salary and imputed bonus amount) and the
actual cash salary and bonus paid to them in the applicable quarter of 2000,
by the Fair Market Unit Value. The "Fair Market Unit Value" shall mean $2.10
through December 31, 2000, and thereafter shall be determined on each
calendar quarter to be the lesser of: (i) 120 times the gross revenues of the
Partnership for the month immediately preceding the month of determination
and then divided by the number of Units outstanding; or (ii) the highest
sales price of any Units sold by the Partnership, if any, during any of the
four months immediately preceding determination.

SECOND AMENDMENT TO AGREEMENT
OF LIMITED PARTNERSHIP OF RACKSPACE, LTD.                                     18

<PAGE>

               (ii) Weston and Miller may elect at the beginning of each
calendar quarter (or for the entire year at their election), during 2000,
2001 and 2002 to forgo some or all of their monthly salary and earn the right
to receive options to acquire Units. Miller and Weston, to the extent that
they elect not to receive any salary (or to the extent that elect to receive
part cash, then the difference between the cash compensation received and the
applicable compensation level for that year) they will receive options to
acquire such number of Units determined by dividing the difference between
the amount of their monthly salary earned for such quarter and the amount of
the cash salary, if any, actually paid to them in the applicable quarter, by
the Fair Market Unit Value.

               (iii) The foregoing options to Certain Key Personnel shall be
earned and calculated on a quarterly basis throughout the year and granted at
the end of each year. The exercise price of the options shall be $.01 per
Unit (payable in cash or netted out of the number of Units granted). The
options shall be subject to forfeiture by each of the Certain Key Personnel
if their employment with the Partnership (or any successor entity) is
terminated voluntarily or involuntarily, for cause, or without cause, prior
to June 30, 2001, unless employment is terminated due to death, disability,
or in connection with the sale of substantially all the ownership interests
or assets of the Partnership (whether by sale, merger or other transaction)
to a third party.  In the event of such forfeiture, the terminated employee
shall be entitled to receive the salary he would have received during the
time of employment but for his election to earn the options.

          c.   The option agreements for the Certain Key Personnel (including
amendments, as necessary, to the employment agreements of Yoo, Condon and
Elmendorf) shall contain the terms as outlined in Section 17(b)(i), (ii)
and (iii) above, be in a form acceptable to the General Partner and shall
contain anti-dilutions provisions, forfeiture provisions upon termination of
employment or competition with the Partnership, and other provisions which
are customary and reasonable.

     18.  ASSIGNMENT OF CERTAIN RIGHTS.  Notwithstanding anything in the
Partnership Agreement or this Second Amendment to the contrary, a Limited
Partner which has executed this Second Amendment may assign any right of
first refusal, preemptive right or other right to acquire Units to any (i)
current limited partner, partner, shareholder or member of such Limited
Partner, or an Affiliate of such Person, or an entity controlled by such
Persons or their Affiliates, or (ii) another Person upon the prior consent of
the General Partner in the General Partner's sole discretion (a "Current
Affiliate") and provide the General Partner written notice of such assignment
within five (5) Business Days. Upon any such assignment, the Current
Affiliate shall be subject to the rights, obligations, and restrictions
provided in the Partnership Agreement (as amended) with respect to exercising
any such rights and becoming a Limited Partner or Substitute Limited Partner.

     19.  REPRESENTATION. The parties to this Second Amendment acknowledge
that the law firm of Matthews and Branscomb, P.C. has assisted in the
preparation of this document on behalf of and as counsel for Trout, Ltd. and
the General Partner, and further acknowledge that the Partnership will pay
the fees and expenses associated with such services.

<PAGE>

                               THIRD AMENDMENT TO
                        AGREEMENT OF LIMITED PARTNERSHIP

                                       OF

                                 RACKSPACE, LTD.

         This Third Amendment to Agreement of Limited Partnership of
Rackspace, Ltd. (hereinafter referred to as the "Third Amendment") is made
this 22nd day of February, 2000, by and among Rackspace, Ltd. (the
"Partnership"), Macroweb, LC, a Texas limited liability company (the "General
Partner" or "Macroweb"), Trout, Ltd., a Texas limited partnership ("Trout"),
Richard Yoo ("Yoo"), Patrick Condon ("Condon") and Dirk Elmendorf
("Elmendorf"), Isom Capital Partners I, L.P. ("Isom"), First Inning
Investors, L.P. ("First Inning"), The Hamilton Companies LLC, a Colorado
limited liability company ("Hamilton"), Weston Investment Interest, L.L.C., a
Nevada limited liability company ("Weston Entity"), MiniPat & Company, Ltd.,
a Texas limited partnership ("MiniPat")(Macroweb, Trout, Yoo, Condon,
Elmendorf, Isom, First Inning, Hamilton, Weston Entity and MiniPat are
sometimes referred to herein as the "Existing Partners") and 2M Technology
Ventures, L.P. (the "New Partner" or "2M"). This Third Amendment amends the
Agreement of Limited Partnership dated December 29, 1998, as amended on
September 29, 1999 (the "First Amendment") and again on November 30, 1999
(the "Second Amendment," and collectively, hereinafter referred to as the
"Agreement" or "Partnership Agreement"). Except as amended by this Third
Amendment, the Second Amendment and the First Amendment to Agreement of
Limited Partnership of Rackspace, Ltd., the terms of the Partnership
Agreement shall continue in full force and effect. Capitalized terms used
herein shall, unless otherwise specified, have the meanings assigned to them
in the Partnership Agreement.

         WHEREAS, Hamilton has exercised its right to contribute an
additional $500,000.00 to the Partnership and thereby receive an additional
238,095.24 Units to be held as a Class C Limited Partner; and

         WHEREAS, 2M desires to contribute $250,000.00 to the Partnership, to
become a Class C Limited Partner and to receive 119,047.62 Units in
accordance with the terms of this Agreement.

         WHEREAS, the Partnership and the Existing Partners desire to have 2M
make an investment in the Partnership as set forth herein and to have it
become a Limited Partner of the Partnership.

         NOW, THEREFORE, FOR AND IN CONSIDERATION OF THE MUTUAL PROMISES
HEREIN MADE, THE PARTIES AGREE AS FOLLOWS:

         1. ADMISSION OF NEW PARTNER. Upon the execution of this Third
Amendment by all the parties hereto, effective January 21, 2000 2M shall
become an Additional Limited Partner of the

<PAGE>

Partnership as a "Class C Limited Partner," having the rights and interests
of a Class C Limited Partner as set forth in the Second Amendment except as
otherwise provided herein.

         2. CONTRIBUTION OF CAPITAL.

            a.  Upon the execution of this Third Amendment, 2M shall
contribute $250,000.00 to the Partnership (the "New Contribution to Capital")
and effective January 21st, 2000 shall be deemed to have received 119,047.62
Units as a Class C Limited Partner.

            b.  On January 21st, 2000 Hamilton contributed an additional
$500,000.00 to the Partnership and received 238,095.24 additional Units as a
Class C Limited Partner.

         3. CAPITAL ACCOUNTS. The parties to this Third Amendment have made a
determination that the fair market value of the assets of the Partnership,
immediately prior to the contributions by Hamilton and 2M described in 2
above, was $30,810,000.00 (the "Valuation"). However, the parties further
agree that the value of the assets is extremely speculative and may in fact
be substantially more or substantially less than $30,810,000.00. The number
of Units received by Hamilton and 2M are based upon the parties' mutual
determination that the value of the Partnership's assets immediately prior to
closing of the sale of such additional Units is $30,810,000.00. The parties
agree as of and immediately prior to January 21, 2000, the Partners' Capital
Accounts shall be adjusted to reflect the Valuation and the Partners'
distributive shares of tax items shall be determined all in accordance with
Treasury Regulation 1.704-1(b)(2)(iv)(f) and (g). The parties further agree
that immediately prior to any subsequent contribution to the Partnership or
distribution from the Partnership, Capital Accounts shall be adjusted in
accordance with the provisions of Code Section 704(b) and the Regulations,
including Treasury Regulation 1.704-1(b)(2)(iv)(f) and (g).

         4. OWNERSHIP PERCENTAGES AND UNITS. As a result of the contributions
of capital set forth in paragraph 3 above, the Ownership Percentage Interests
and number of Units held by each Partner is as follows:

                                 FOURTH AMENDMENT TO
                           AGREEMENT OF LIMITED PARTNERSHIP

                                          OF

                                   RACKSPACE, LTD.

       This Fourth Amendment to Agreement of Limited Partnership of Rackspace,
Ltd. (hereinafter referred to as the ("Fourth Amendment") is made effective the
27 day of March, 2000 (the "Effective Date"), by and among Rackspace, Ltd. (the
"Partnership"), Macroweb, LC, a Texas limited liability company (the "General
Partner" or "Macroweb"), Trout, Ltd., a Texas limited partnership ("Trout"),
Richard Yoo ("Yoo"), Patrick Condon ("Condon"), Dirk Elmendorf ("Elmendorf"),

Partners"), Norwest Venture Partners VII, L.P. ("Norwest"), Red Hat, Inc. ("Red
Hat") and Tailwind Capital Partners 2000, L.P. ("Thomas Weisel").  This Fourth
Amendment amends the Agreement of Limited Partnership dated December 29, 1998,
as amended on September 29, 1999 (the "First Amendment"), on November 30, 1999
(the "Second Amendment") and again on February 22, 2000 (the "Third Amendment")
(collectively, hereinafter referred to as the "Agreement" or  the  "Partnership
Agreement"). Except as amended by this Fourth Amendment, the Third Amendment,
the Second Amendment and the First Amendment to Agreement of Limited Partnership
of Rackspace, Ltd., the terms of the Partnership Agreement shall continue in
full force and effect.  Capitalized terms used herein shall, unless otherwise
specified, have the meanings assigned to them in the Partnership Agreement.

       WHEREAS,  Norwest desires to contribute $5,750,000, to become  a Class C
Limited Partner and to receive Units in accordance with the terms of this
Agreement.

       WHEREAS, Red Hat desires to contribute $2,000,000, to become a Class C

Agreement.

       WHEREAS, Thomas Weisel desires to contribute $300,000, to become a Class

<PAGE>

       WHEREAS, the Partnership and the Existing Partners desire to have
Norwest,  Red Hat and Thomas Weisel invest in the Partnership as set forth
herein and to have them become Limited Partners of the Partnership.

       NOW, THEREFORE, FOR AND IN CONSIDERATION OF THE MUTUAL PROMISES HEREIN
MADE, THE PARTIES AGREE AS FOLLOWS:

       1.     ADMISSION OF NEW PARTNERS.  Upon the execution of this Fourth
Amendment by all the parties hereto, effective the date set forth above,
Norwest,  Red Hat and Thomas Weisel shall become Additional Limited Partners of
the Partnership as  "Class C Limited Partners",  having the rights and interests
of  Class C Limited Partners as set forth in the Second Amendment except as
otherwise provided herein. For the purposes hereof, references to the "Partners"
or the "Limited Partners" shall include Norwest, Red Hat and Thomas Weisel.

       2.     CONTRIBUTION OF CAPITAL/WARRANTS.  Upon the execution of this
Fourth Amendment,  (i) Norwest shall contribute $5,750,000 to the Partnership
and shall receive 1,015,901 Class C Units to be held as a Class C Limited
Partner,  (ii) Red Hat shall contribute $2,000,000 to the Partnership and shall
receive 353,356.89 Class C Units to be held  as  a Class C Limited Partner, and
Thomas Weisel shall contribute $300,000 to the Partnership and shall receive
53,003.53 Class C Units to be held as a Class C Limited Partner (collectively,
the "New Contributions to Capital).  In addition, Norwest shall receive a
warrant (the "Norwest Warrant") to purchase an amount of Class C Units (which
have the same rights and obligations as the Units initially purchased by
Norwest), determined by dividing $3,000,000 by the greater of the $18.24 or the
mid-point in the filing range (the "Mid-point") set forth in the preliminary
prospectus (commonly referred to as the "red herring") which is first circulated
by the Company.  After the Mid-point is established, the warrant may be
exercised at anytime before one year after the date of issuance, unless the
Mid-point is not established within four months of the date hereof, in which
case it may be exercised after four months from the date of issuance.  A copy of
the warrant is attached as Exhibit A.

       3.     CAPITAL ACCOUNTS.   The parties to this Fourth Amendment have made
a determination that the fair market value of the assets of the Partnership,
immediately prior to the contributions by Norwest, Red Hat and Thomas Weisel
described in 2 above, was $85,000,000.00 (the "Valuation"). However, the parties
further agree that the value of the assets is extremely speculative and may in
fact be substantially more or substantially less than $85,000,000.   The number
of Units received by Norwest, Red Hat and Thomas Weisel is  based upon the
parties' mutual determination that the value of the Partnership's assets
immediately prior to the Effective Date, was $85,000,000. The parties agree as
of and immediately prior to the Effective Date, the Partners' Capital Accounts
shall be adjusted to reflect the Valuation and the Partners' distributive shares
of tax items shall be determined all in accordance with Treasury Regulation
1.704-1(b)(2)(iv)(f) and (g).   The parties further agree that immediately prior
to any subsequent contribution to the Partnership or distribution from the
Partnership, Capital Accounts shall be adjusted in accordance with the
provisions of Code Section 704(b) and the Regulations,  including  Treasury
Regulation 1.704-1(b)(2)(iv)(f) and (g). The Capital Accounts of all of the
Partners as of the Effective Date are as set forth on Exhibit "B" attached
hereto.

       5.     NEW INVESTORS.  It is expressly agreed that the General Partner
may cause the Partnership to issue up to  530,035.34 Class C Units (the
"Additional Units") to one or more additional persons or entities (the "New
Investors") and to admit them as Class C Limited Partners, provided that the
aggregate purchase price per Unit is not less than $5.66 per Unit.  In addition,
the General Partner may cause the Partnership to issue a warrant to the New
Investors with the same terms as contained in the Norwest Warrant, including
terms as to amount of Units subject to purchase, price, and the time period in
which it may be exercised.   It is the intention of the parties hereto that such
New Investors shall have the benefits and obligations of the Class C Limited
Partners, except to the extent limited by paragraph 7 below,  and that they may
become signatories to this Agreement without any further consent or agreement of
the parties to this agreement.  To the extent that such New Investors become
parties to this agreement, the schedule set forth in paragraph 4 above shall be
appropriately

                                          3
<PAGE>

adjusted and the capital accounts of all the Partners will be "booked-up" in
accordance with paragraph 3 above at the time of the investment to reflect the
valuation of the Partnership at that time.  To the extent that the New Investors
are admitted to the Partnership, for the purposes hereof, references to the
"Partners" or the "Limited Partners" shall include the New Investors.

       6.     WAIVER OF PRE-EMPTIVE RIGHTS.  The parties to this Agreement
hereby waive any pre-emptive rights that they may have to acquire Units issued
by the Partnership, but only with respect to the Units issued by the Partnership
which are set forth in 4 above, Units issued upon options in effect prior to the
date hereof, or Units issued to New Investors under paragraph 5 above, and not
with respect to any Units issued by the Partnership after the date of this
Agreement.  In addition, with respect to the Units purchased by Norwest, Red
Hat, Thomas Weisel and the New Investors, if any, the parties hereto waive any
rights of first refusal which may exist with respect to the resale of those
Units by any of them.

       7.     RIGHT TO APPOINT DIRECTORS.  Notwithstanding Section 9(h) of the
Second Amendment to the Agreement of Limited Partnership of Rackspace, Ltd. to
the contrary, Norwest, Red Hat, Thomas Weisel and the New Investors, if any,
shall not have the right to participate with the other Class C Limited Partners
in designating one director or manager of the Successor Entity under the terms
set forth in such Section 9(h), nor for the purposes of Section 9(h) shall
Norwest's, Red Hat's, Thomas Weisel's or the New Investors equity interest in
the Partnership be included in determining whether the Class C Limited Partners
hold 10% of the equity interests of the Successor Entity.

       8.     PARTIES BOUND/ADDITIONAL AGREEMENTS.  The parties hereto agree
that Norwest, Red Hat, Thomas Weisel and the New Investors, if any,  by
executing this Fourth Amendment, are bound to and have the benefit of the terms
contained herein as well as the terms contained in the First Amendment, the
Second Amendment, the Third Amendment and the Partnership Agreement as if they
had become direct signatories to such agreements.

       9.     REPRESENTATION.  The parties to this Fourth Amendment acknowledge
that the law firm of Matthews and Branscomb, P.C. has assisted in the
preparation of this document on behalf of and as counsel for Trout, Ltd. and the
General Partner, and further acknowledge that the Partnership will pay the fees
and expenses associated with such services.

       10.    MULTIPLE COUNTERPARTS.   This Fourth Amendment may be executed in
one or more  counterparts, each of which shall be deemed an original but all of
which together will constitute one and the same instrument.

                                    WARRANT

     This Agreement (herein the "AGREEMENT") is entered into effective the
30th day of November, 1999 (herein the "EFFECTIVE DATE"), by and between
RACKSPACE, LTD. (herein "RACKSPACE"), a Texas limited partnership whose sole
general partner is Macroweb, LC, a Texas limited liability company, and
TRANGO CAPITAL, L.L.C., a Texas limited liability company (herein "TRANGO").

     WHEREAS, Rackspace is in the business of offering web-server hosting
services through the leasing of internet servers, bandwidth, connectivity and
administration of all aspects of servers; and

     WHEREAS, Trango is the sole general partner of First Inning Investors,
L.P., a Texas limited partnership (herein "FIRST INNING"); and

     WHEREAS, contemporaneous with the execution of this Agreement, First
Inning is investing One Million Three Hundred Thousand and No/100 Dollars
($1,300,000.00) in Rackspace (herein the "FIRST INVESTMENT"), which
investment is being made, in part, in consideration for the agreement of
Rackspace to provide to Trango a warrant to make a substantial additional
investment in Rackspace, all as provided herein;

     NOW, THEREFORE, in consideration of the premises herein set out, and Ten
Dollars and other valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, Rackspace and First Inning agree as follows:

1.   OPTION TO INVEST.

     Trango will have the option (but not the obligation) to acquire all (but
not less than all) of the Option Interest (as hereinafter defined) in
consideration for the payment to Rackspace of the Purchase Price (as
hereinafter defined) (herein the "OPTION TO INVEST"). If Trango exercises
such Option to Invest, it shall acquire the Option Interest through a new
limited partnership to be formed, of which Trango will be sole general
partner, which will be pursuant to a limited partnership agreement on
substantially the same terms as the Agreement of Limited Partnership of First
Inning, with the limited partners being one or more of the Limited Partners
of First Inning and/or Melvin Lachman, the specific limited partners and the
percentage of ownership of each shall be determined by Trango, in its sole
and absolute discretion (herein "FIRST INNING II").

<PAGE>

2.   EXERCISE OF OPTION.

     The Option to Invest may be exercised by Trango providing to Rackspace
written notice of the exercise by Trango of such option (herein the "NOTICE OF
EXERCISE") at any time from the Effective Date hereof through 5 p.m., CST, on
December 31, 2001 (herein the "OPTION PERIOD").

3.   PURCHASE PRICE.

     The Purchase Price for the Option Interest is Eight Hundred Thousand and
No/100 Dollars ($800,000.00), to be paid by First Inning II to Rackspace at the
Closing (as hereinafter defined).

4.   OPTION INTEREST.

     4.1  For purposes of this Agreement:

          (a)  The interest acquired by First Inning for the First Investment,
     as subsequently altered by virtue of any merger, exchange or dilution for
     other investment in Rackspace (or its successor-in-interest), if any, is
     herein referred to as the "INITIAL INVESTMENT";

          (b)  The OPTION INTEREST, as that term is used in this Agreement,
     shall be an interest equal to 61.5385% (that is, $800,000 DIVIDED BY
     $1,300,000) of the then Initial Investment (that is, of the same quality
     and character of investment in the same entity [e.g., undivided limited
     partnership interest, or shares in corporation, or membership interests in
     a limited liability company] but only 61.5385% of the equity interest
     represented by the First Investment at the time of exercise of the Option).

     4.2  In consideration for the payment of the Purchase Price by First
Inning II as herein provided, at the Closing, Rackspace will transfer and
assign the Option Interest to First Inning II, free and clear of any liens or
encumbrances.

     4.3  The Option Interest will have all of the rights and privileges
generally available to other Limited Partners of Rackspace.

5.   CLOSING.

     The Closing shall occur at the offices of Rackspace within ten (10)
business after the Notice of Exercise is delivered by Trango to Rackspace.

<PAGE>

6.   SALE OR MERGER.

     6.1  In the event that, during the Option Period while Trango has not yet
exercised the Option to Invest, all or substantially all of the ownership/equity
interests (i.e., undivided limited partnership, or shares in a corporation, or
membership interests in a limited liability company, as the case may be) in
Rackspace, or all or substantially all of the assets of Rackspace, are to be
sold, then Rackspace will provide to Trango not less than fifteen (15) business
days prior written notice of such sale and the terms and provisions of such sale
(herein the "NOTICE OF INTENT TO SELL"), and Trango will be entitled to exercise
the Option to Invest prior to consummation of such sale, and the Option Interest
acquired by First Inning II will participate fully and ratably (that is, with
all other ownership/equity interests) in such sale; provided, however, if Trango
fails to exercise the Option to Invest within such 15 business days and
consummate the purchase of the Option Interest within such 15 days, then the
Option to Invest will lapse and be of no further force and effect.

     6.2  In the event that during the Option Period while Trango has not yet
exercised the Option to Invest, Rackspace contemplates a merger or exchange
which will result in the then owners of the ownership/equity in Rackspace
receiving ownership/equity in any other entity, then Rackspace will provide
to Trango not less than fifteen (15) business days prior written notice of
such merger or exchange and the terms and provisions of such merger or
exchange (therein the "NOTICE OF INTENT TO SELL"), and Trango will be
entitled to exercise the Option to Invest prior to consummation of such
merger or exchange, and the Purchase Price paid by First Inning II will be
taken into consideration in valuation of the assets of Rackspace in
determining the valuation to be used in such merger or exchange, and the
Option Interest acquired by First Inning II will participate fully and
ratably (that is, with all other ownership/equity interests) in such sale or
exchange; provided, however, if Trango fails to exercise the Option to Invest
within such fifteen (15) business days, the Option to Invest will NOT lapse
prior to the end of the Option Period and the Option Interest will be in the
proportionate interest (i.e., 61.5385%) of the interest received and
thereafter held in exchange for the Initial Investment.

7.   ACCESS TO BOOKS AND RECORDS.

     From the Effective Date hereof until the expiration of the Option Period:

          (a)  Trango (though its designated representative or agent) will be
     provided access from time to time to the books and records of Rackspace
     during normal business hours, and upon not less than 48 hours prior written
     notice, for the purpose of determining the financial condition of and value
     of interests in Rackspace; and

          (b)  Rackspace will provide to Trango copies of all unaudited and/or
     audited operating statements and financial statements (monthly, quarterly
     and/or annually) as Rackspace shall prepare or have prepared for the
     benefit of its management, lender(s) or partners.

8.   REPRESENTATIONS AND WARRANTIES OF RACKSPACE.

     8.1  Rackspace does hereby make the following representations and
warranties to Trango, and will again at the Closing make the following

     is a party (including, without limitation, its partnership agreement), the
     effect of which will materially adversely affect performance by Rackspace
